ABSTRACT

Introducción: La prevalencia del cáncer de tiroides es del 4 al 7%, en Ecuador alcanza una tasa de 16/100.000 habitantes, en la mayoría de casos requiere resolución quirúrgica asociando una tasa de complicaciones del 2 al 15%, de estas la hipocalcemia representa al menos el 10.9%. El objetivo del presente estudio fue evaluar la utilidad de la medición de la hormona paratiroidea sérica (PTH) como predictor de hipocalcemia posterior a tiroidectomía. Métodos: Se realizó un estudio transversal analítico de pacientes con tiroidectomía en el Hospital Metropolitano de Quito, en el periodo enero del 2017 a diciembre del 2019. Se analizaron variables demográficas, clínicas, quirúrgicas y complicaciones. Se comparó la relación de la PTH con la presencia de hipocalcemia clínica, serológica o ambas mediante RP, sensibilidad, especificidad, VPP, VPN, LR. Otras variables confusoras se analizaron mediante regresión logística multinomial comparando sus OR. Resultados: Se incluyeron 212 registros, 15.6% hombres y 84.4% mujeres, con promedio de 52.1 años. La indicación principal de tiroidectomía fue por Carcinoma papilar 123 (58.0%). Las complicaciones fueron el 22.7%. Un total de 48 pacientes desarrollaron hipocalcemia. Los niveles de PTH < 10 ng/l predicen la hipocalcemia con sensibilidad de 0.55, especificidad 0.78, VPP: 43%, VPN: 85%, RP fue 2.91 (IC 95% 1.06 - 8.01). Conclusiones: La cuantificación de PTH en 10 ng/l o menos, es útil para predecir hipocalcemia clínica en los pacientes sometidos a tiroidectomía total.


Introduction: The prevalence of thyroid cancer is from 4 to 7%; in Ecuador, it reaches a rate of 16/per 100,000 inhabitants; in most cases, it requires surgical resolution associated with a complication rate of 2 to 15%, of this hypocalcemia represents at least minus 10.9%. This study aimed to evaluate the usefulness of measuring serum parathyroid hormone (PTH) as a predictor of hypocalcemia after thyroidectomy. Methods: An analytical cross-sectional study of patients with thyroidectomy was carried out at the Metropolitan Hospital of Quito from January 2017 to December 2019. Demographic, clinical, surgical, and complication variables were analyzed. PTH's relationship with clinical or serological hypocalcemia or both was compared using PR, sensitivity, specificity, PPV, NPV, and LR. Other confounding variables were analyzed using multinomial logistic regression comparing their ORs. Results: A total of 212 records were included, 15.6% men and 84.4% women, with an average age of 52.1 years. The main indication for thyroidectomy was papillary carcinoma 123 (58.0%). Complications were 22.7%. A total of 48 patients developed hypocalcemia. PTH levels < 10 ng/l predict hypocalcemia with a sensitivity of 0.55, specificity of 0.78, PPV: 43%, NPV: 85%, and PR was 2.91 (95% CI 1.06 - 8.01). Conclusions: PTH quantification of 10 ng/l or less helps predict clinical hypocalcemia in patients undergoing total thyroidectomy.

ABSTRACT

INTRODUCTION: Kidney transplantation (KT) is the renal replacement therapy (RRT) of choice for patients with chronic kidney disease (CKD). However, not every KT is successful and some patients persist on RRT. OBJECTIVE: To model a logistic regression with pre- and post-KT risk covariates capable of predicting secondary allograft dysfunction in need of RRT or reaching stage V of CKD until the first six months post-KT. METHODS: Cohort with KT recipients from Northeastern Brazil. Medical records of KT performed between 2011-2018 were analyzed. KT-recipients with insufficient data or who abandoned follow-up were excluded. The covariables analyzed were: demographic; infectious; pre- and post-KT comorbidities; panel reactive-antibodies; number of HLA mismatches; acute rejection episodes mediated by T-cell (ACR) or antibodies (AAR) six months after KT; and laboratory tests six months after KT. RESULTS: Covariates with higher risk for the analyzed outcomes six months after KT were: elderly KT recipients (OR:1.41; CI95%:1.01-1.99), time between onset of RRT and KT (ΔT-RRT&KT)>10years (OR:3.54; CI95%:1.27-9.87), diabetes mellitus (DM) pre-KT (OR:3.35; CI95%:1.51-7.46), pyelonephritis (OR:2.45; CI95%:1.24-4.84), polyomavirus nephropathy (OR:4.99; CI95%:1.87-13.3), AAS (OR:4.82; CI95%:1.35-17.2), 24h-proteinuria ≥300mg/24h (OR:5.05; CI95%:2.00-12.7) and serum calcium (Ca) <8.5mg/dL (OR:4.72; CI95%:2.00-11.1). The multivariate model presented an accuracy of 88.1% and the mean variance inflation factor is 1.81. CONCLUSION: Elderly-recipients, ΔT-RRT&KT>10 years, pre-KT DM, and post-KT aggressions until six months (pyelonephritis, polyomavirus nephropathy, ABMR, 24h-proteinuria≥300mg/24h, and Ca<8.5mg/dL) are associated with high predictive power for secondary allograft dysfunction in need of RRT or reaching CKD stage V until the first six months post-KT.


INTRODUÇÃO: Transplante renal (TR) é a terapia renal substitutiva (TRS) de escolha para pacientes com doença renal crônica (DRC). Entretanto, nem todo TR é bem-sucedido e alguns pacientes persistem em TRS. OBJETIVO: Modelar uma regressão logística com covariáveis de risco pré e pós-TR preditora da disfunção secundária do aloenxerto com necessidade de TRS ou alcance ao estágio V da DRC até os primeiros seis meses pós-TR. MÉTODOS: Coorte com receptores transplantados realizado em hospital no Nordeste brasileiro. Analisou-se registros médicos dos TR realizados entre 2011-2018. Receptores com dados insuficientes ou que abandonaram seguimento foram excluídos. Foram analisadas covariáveis: demográficas; infecciosas; comorbidades pré e pós-TR; painel de reatividade; incompatibilidades de HLA; episódios de rejeições agudas mediadas por células-T ou por anticorpos; exames laboratoriais seis meses pós-TR. RESULTADOS: Receptores idosos (OR:1,41; IC95%:1,01-1,99), tempo entre início da TRS e TR (∆T-TRS&TR)>10 anos (OR:3,54; IC95%:1,27-9,87), diabetes mellitus (DM) pré-TR (OR:3,35; IC95%:1,51-7,46), pielonefrite (OR:2,45; IC95%:1,24-4,84), nefropatia por poliomavírus (OR:4,99; IC95%:1,87-13,3), RAMA (OR:4,82; IC95%:1,35-17,2), proteinúria de 24h (Pt24h) ≥300mg/24h (OR:5,05; IC95%:2,00-12,7) e cálcio sérico (Ca)<8,5mg/dL (OR:4,72; IC95%:2,00-11,1) foram identificadas como covariáveis de maior risco para os desfechos analisados até seis meses pós-TR. O modelo multivariado apresentou acurácia de 88,1% e fator de inflação da variância médio de 1,81. CONCLUSÃO: Receptores idosos, ∆T-TRS&TR>10anos, DM pré-TR e agressões até seis meses pós-TR (pielonefrite, nefropatia por poliomavírus, RAMA, Pt24h≥300mg/24h e Ca<8,5mg/dL), apresentam alto poder preditivo para disfunção secundária do aloenxerto com necessidade de TRS ou alcance ao estágio V da DRC até os primeiros seis meses pós-TR.

ABSTRACT

INTRODUCCIÓN: el hipoparatiroidismo es la alteración causada por hipofunción de las glándulas paratiroides y la causa más común es la posquirúrgica. OBJETIVO: conocer la incidencia de hipocalcemia dentro de las 72 horas del postoperatorio y de hipoparatiroidismo permanente de tiroidectomías en nueve años. SUJETOS Y MÉTODO: estudio observacional, descriptivo y retrospectivo de pacientes con tiroidectomías entre enero de 2011 y diciembre de 2019 en el Hospital de Clínicas. Se dividió la muestra por grupos etarios, se consideró hipocalcemia a valores ≤8,5 mg/dl e hipoparatiroidismo permanente cuando persistían por lo menos un año luego de cirugía. RESULTADOS: fueron 202 pacientes, 182 mujeres y 20 hombres, media de edad ± ES para mujeres 47.3±1.2 años y para hombres 55.1±3.4. El 61,5% presentó hipocalcemia en las primeras 72 horas del postoperatorio: 60,2% de mujeres y 71,4% de hombres (p=0.42). El 79% fueron hipocalcemias asintomáticas, 7,5% tuvo síntomas y 13,5% sin datos. El signo de Trousseau fue negativo 68% y positivo en 9%. Respecto a la patología hubo 107 resultados benignos, 94 malignos. CONCLUSIONES: el 90% fueron mujeres, 6 de cada 10 presentaron hipocalcemia en las primeras 72hs, en la gran mayoría fueron asintomáticas y tuvieron signo de Trousseau negativo. No hubo correlación entre hipocalcemia con edad, sexo, duración o tiempo de la cirugía, ni resultado de patología. La incidencia de hipoparatiroidismo transitorio fue 75,7% y permanente 7,3%. Cuando no hubo hipoparatiroidismo transitorio tampoco hubo hipoparatiroidismo permanente.


INTRODUCTION: hypoparathyroidism is the alteration caused by hypofunction of the parathyroid glands and the most common cause is post-surgery. OBJECTIVE: to know the incidence of hypocalcaemia within 72 hours of the postoperative period and of permanent hypoparathyroidism of thyroidectomies in nine years. SUBJECTS AND METHOD: observational, descriptive and retrospective study of patients with thyroidectomies between January 2011 and December 2019 at Clinical's Hospital. The sample was divided by age groups, hypocalcemia was considered at values ≤8.5 mg/dl and permanent hypoparathyroidism when they persisted for at least one year after surgery. RESULTS: there were 202 patients, 182 women and 20 men, mean age ± SE for women 47.3±1.2 years and for men 55.1±3.4. 61.5% presented hypocalcaemia in the first 72 hours after surgery: 60.2% of women and 71.4% of men (p=0.42). 79% were asymptomatic hypocalcemia, 7.5% had symptoms and 13.5% without data. Trousseau's sign was negative in 68% and positive in 9%. Regarding the pathology, there were 107 benign results, 94 malignant. CONCLUSIONS: 90% were women, 6 out of 10 presented hypocalcemia in the first 72 hours, the vast majority were asymptomatic and had a negative Trousseau sign. There was no correlation between hypocalcaemia with age, sex, duration or time of surgery, or pathology result. The incidence of transient hypoparathyroidism was 75.7% and permanent 7.3%. When there was no transient hypoparathyroidism, there was also no permanent hypoparathyroidism.

ABSTRACT

Introducción. La hipocalcemia es la complicación más frecuente de la tiroidectomía. La profilaxis con calcio/calcitriol es una alternativa costo-efectiva, sencilla y expedita para disminuir esta situación, sin alterar la función paratiroidea residual. Lo que no está claro es si hay superioridad de una dosis frente a otra, por lo que el objetivo de este estudio fue evaluar el comportamiento entre diferentes esquemas de profilaxis para hipocalcemia. Métodos. Estudio de cohorte retrospectivo de adultos operados en un hospital de cuarto nivel, entre febrero de 2017 y diciembre de 2020. Se calculó la tasa de síntomas, la hipocalcemia e hipercalcemia bioquímica en el control postquirúrgico durante las siguientes dos semanas. Se hizo análisis bivariado y multivariado entre dosis de calcio/calcitriol, otros factores asociados y los desenlaces mencionados. Resultados. Se incluyeron 967 pacientes. El 10 % presentaron síntomas. No hubo diferencias significativas en el calcio sérico del control posquirúrgico entre los grupos con distintas dosis de calcio. La dosis de carbonato de calcio >3600 mg/día y el calcio en las primeras 24 horas de cirugía se asociaron a la presencia de síntomas. La dosis de calcitriol <1 mcg/día y el bocio aumentaron el riesgo de hipocalcemia bioquímica, mientras que la dosis de 1,5 mcg/día lo disminuyó. Ninguna variable evaluada se asoció a hipercalcemia bioquímica. Conclusiones. Podemos establecer que dosis altas de carbonato de calcio no se asocian con menos hipocalcemia bioquímica, lo cual está a favor de usar dosis intermedias (3600 mg/día). De forma similar, la dosis de calcitriol de 1,5 mcg/día disminuye el riesgo de este desenlace. La identificación de variables que aumentan o disminuyen el riesgo de hipocalcemia posterior a tiroidectomía, como bocio o el nivel de calcio en las primeras 24 horas para este estudio, pueden determinar ajustes individuales en la dosis rutinaria profiláctica de calcio/calcitriol.


Introduction. Hypocalcemia is the most frequent complication of thyroidectomy. Calcium/calcitriol prophylaxis is a cost-effective, simple and expeditious alternative to reduce this situation, without altering residual parathyroid function. It is not clear whether there is superiority of one dose over another, so the objective of this study was to evaluate the behavior between prophylaxis doses for hypocalcemia. Methods. Retrospective cohort study of adults operated in a fourth level hospital, between February 2017 and December 2020. The rate of symptoms, biochemical hypocalcemia and hypercalcemia was calculated in the post-surgical control during the following two weeks. Bivariate and multivariate analyses were performed between calcium/calcitriol dose, other associated factors, and the mentioned outcomes. Results. Out of the 967 patients included, 10% presented symptoms. There were no significant differences in postoperative control serum calcium between the groups with different doses of calcium. The dose of calcium carbonate > 3600 mg/day and calcium in the first 24 hours of surgery were associated with the presence of symptoms. The dose of calcitriol <1 mcg/day and goiter increased the risk of biochemical hypocalcemia, while the dose of 1.5 mcg / day decreased it. No variable evaluated was associated with biochemical hypercalcemia. Conclusion. We can establish that high doses of calcium are not less associated with biochemical hypocalcemia, which is in favor of intermediate doses (i.e. 3600mg/day). In a similar way, the calcitriol dose of 1.5mcg/day decreases the risk of this outcome. The identification of variables that increase or decrease the risk of this complication (goiter or the 24h serum calcium in this study) can decide settings in the rutinary prophylactic dose of calcium/calcitriol.

ABSTRACT

Introducción: Los inhibidores de la bomba de protones son fármacos usados en múltiples gastropatías. El omeprazol pertenece a este grupo de medicamentos y es aprobado y catalogado como indispensable por la Organización Mundial de la Salud. Esto ha causado que su uso se vuelva constante y hasta cierto punto equívoco. Pese a ser medicamentos seguros muestran efectos secundarios, dentro de los cuales uno ocasional es el trastorno hidroelectrolítico. Objetivo: Presentar un caso clínico en el cual se constató la presencia de efectos secundarios tras el uso de un fármaco de uso constante por la comunidad médica: el omeprazol. Caso clínico: Se presenta a continuación el caso clínico de un paciente masculino con antecedente de hipertensión arterial y gastropatía crónica que muestra uso por 8 años consecutivos de inhibidores de la bomba de protones, al cual se le diagnostica hipomagnesemia e hipocalcemia. Se obtuvieron resultados de laboratorio normales tras administración de suplementos orales y uso de ranitidina con supresión de terapéutica con omeprazol. Conclusiones: Un control constante de los fármacos que usan los pacientes crónicos es fundamental en atención primaria de salud. El uso de inhibidores de la bomba de protones se ha convertido en rutinario y es necesario corroborar siempre la dosis y el tiempo de uso de los fármacos además de la relación con otros medicamentos que use el paciente(AU)


Introduction: Proton-pump inhibitors are drugs used in multiple gastropathies. Omeprazole belongs to this group of medicines; it is approved and classified as essential by the World Health Organization. This has permitted for its use to become constant and, to some extent, misleading. Despite being safe drugs, they show side effects, among which an occasional one is fluid and electrolyte disorders. Objective: To present a clinical case in which the occurrence of side effects was verified after the administration of a drug constantly used by the medical community. Clinical case: The following is a clinical case of a male patient with a history of arterial hypertension and chronic gastropathy, characterized by the usage of proton-pump inhibitors for eight consecutive years, diagnosed with hypomagnesemia and hypocalcemia. Normal laboratory results were obtained after oral supplementation and usage of ranitidine with suppression of omeprazole therapy. Conclusions: Constant control of the drugs used by chronic patients is essential in primary health care. The usage of proton-pump inhibitors has become a routine. It is always necessary to check the dose and time for using the drugs as well as the relationship with other drugs used by the patient(AU)

ABSTRACT

Abstract Background: To the best of our knowledge, there are studies related to QT and QTc interval in patients with hypocalcemia, but there are no studies evaluating T wave peak and end interval (Tp-e interval), Tp-e/QT and Tp-e/QTc ratios used to evaluate cardiac arrhythmia risk and ventricular repolarization changes rates. Objectives: Therefore, we aimed to investigate whether there is a change in Tp-e interval, Tp-e/QT and Tp-e/QTc ratios in patients with hypocalcemia. Methods: Retrospectively, 29 patients with hypocalcemia in the emergency department were included in the study. Twenty-nine patients with similar age and sex distribution were included in the study as the control group. All patients underwent 12-lead electrocardiography (ECG). In addition to routine measurements, Tp-e interval, Tp-e/QT and Tp-e/QTc ratios were measured on ECG. The study data were grouped as patients with and without hypocalcemia. Results: The mean age of the patients was 66.24 ± 4.95 years. QTc interval, Tp-e interval and Tp-e/QTc values were found to be significantly higher in patients with hypocalcemia (p <0.001 for each). QTc interval, Tp-e interval and Tp-e/QTc ratio showed a significant negative correlation with calcium levels. Conclusion: Tp-e interval and Tp-e/QTc ratios are significantly increased in patients with hypocalcemia compared to those without hypocalcemia and this can be used more effectively in the follow-up of cardiac fatal arrhythmias.

ABSTRACT

RESUMEN La hipomagnesemia es un trastorno electrolítico asociado con la disminución de los aportes nutricionales, las pérdidas gastrointestinales y la depuración renal del magnesio, un catión divalente que, al tener una mayor concentración a nivel intracelular, dificulta el análisis de su déficit absoluto y el establecimiento de una adecuada corrección que supla las pérdidas y los requerimientos diarios que son aproximadamente 360 mg por día. Es por esto que el conocimiento de las etiologías de la hipomagnesemia, al igual que el cálculo de la fracción excretada de magnesio y la medición de la magnesiuria en 24 horas, son herramientas útiles para establecer pautas adecuadas de corrección continua de magnesio con el fin de evitar las complicaciones asociadas con su toxicidad o una corrección deficiente que perpetúe dicho trastorno electrolítico, lo cual puede generar una sintomatología tan grave como la tetania o la insuficiencia respiratoria. La paciente descrita, en ausencia de estado de choque o trastorno ácido base, requirió ingreso a la unidad de cuidados intensivos para ventilación mecánica invasiva y corrección de sus trastornos electrolíticos asociados con la colitis ulcerativa (hipocalcemia, hipocalemia e hipomagnesemia).


SUMMARY Hypomagnesemia is an electrolyte disorder associated with decreased nutritional intake, gastrointestinal losses, and renal clearance of magnesium, a divalent cation that, having a higher concentration at the intracellular level, makes it difficult to analyze its absolute deficit and establish an adequate correction that supplies daily losses and requirements; For this reason, knowledge of the etiologies of hypomagnesemia, as well as the calculation of the excreted fraction of magnesium and measurement of magnesiuria in 24 hours, are useful tools to establish adequate guidelines for continuous magnesium correction, in order to avoid complications associated with its toxicity or poor correction that perpetuates this electrolyte disorder, and generates the appearance of symptoms as severe as tetany and ventilatory failure. These severe manifestations were present in the patient described, who, in the absence of shock or base acid disorder, required admission to the intensive care unit for invasive mechanical ventilation and correction of their electrolyte disorders associated with ulcerative colitis (hypocalcemia, hypokalemia, and hypomagnesemia).

ABSTRACT

Abstract Introduction: Hypocalcemia is one of the most common complications after total thyroidectomy. Preoperative serum vitamin D concentration has been postulated as a risk factor for this complication. However, the subject is still controversial and the role of vitamin D in the occurrence of hypocalcemia remains uncertain. Objective: To evaluate the capability of preoperative vitamin D concentrations in predicting post-total thyroidectomy hypocalcemia. Methods: Forty-seven total thyroidectomy patients were prospectively evaluated for serum 25(OH) vitamin D, calcium and parathyroid hormone before surgery, Calcium every 6 hours, and parathyroid hormone 8 hours post-operatively. Patients were divided according to postoperative corrected calcium into groups without (corrected calcium ≥8.5 mg/dL) and with hypocalcemia (corrected calcium <8.5 mg/dL), who were then evaluated for preoperative 25(OH) vitamin D values. Results: A total of 72.3% of cases presented altered 25(OH) vitamin D preoperative serum concentrations and 51% evolved with postoperative hypocalcemia. The with and without hypocalcemia groups did not differ for preoperative 25(OH) vitamin D (p = 0.62). Univariate analysis showed that age (p = 0.03), postoperative PTH concentration (p = 0.02), and anatomopathological diagnosis of malignancy (p = 0.002) were predictors of postoperative hypocalcemia. In multivariate analysis only parathyroid hormone in postoperative (p = 0.02) was associated with post-total thyroidectomy hypocalcemia. Conclusion: Preoperative serum concentrations of 25(OH) vitamin D were not predictors for post-total thyroidectomy hypocalcemia, whereas postoperative parathyroid hormone influenced the occurrence of this complication.


Resumo Introdução: A hipocalcemia é uma das complicações mais comuns após a tireoidectomia total. A concentração sérica de vitamina D tem sido apontada como fator de risco para essa complicação. No entanto, o assunto ainda é controverso e o papel da vitamina D na ocorrência de hipocalcemia permanece incerto. Objetivo: Avaliar se os níveis pré-operatórios de vitamina D são capazes de predizer a hipocalcemia pós-tireoidectomia total. Método: Quarenta e sete pacientes com tireoidectomia total foram avaliados prospectivamente quanto aos níveis séricos de 25(OH)vitamina D, cálcio e paratormônio antes da cirurgia, cálcio a cada 6 horas e paratormônio 8 horas após a cirurgia. Os pacientes foram divididos de acordo com o cálcio corrigido no pós-operatório em grupos sem (cálcio corrigido ≥ 8,5 mg/dL) e com hipocalcemia (cálcio corrigido < 8,5 mg/dL), que foram avaliados em relação aos valores pré-operatórios de 25(OH)vitamina D. Resultados: 72,3% dos casos apresentaram concentrações séricas pré-operatórias alteradas de vitamina D- 25 hidroxi e 51% desenvolveram hipocalcemia no pós-operatório. Os grupos com e sem hipocalcemia não diferiram para a 25(OH)vitamina D pré-operatório (p = 0,62). A análise univariada mostrou que a idade (p = 0,03), a concentração de paratormônio no pós-operatório (p = 0,02) e o diagnóstico anatomopatológico de malignidade (p = 0,002) foram preditores de hipocalcemia no pós-operatório. Na análise multivariada, apenas o paratormônio no pós-operatório (p = 0,02) foi associado a hipocalcemia pós-tireoidectomia total. Conclusão: As concentrações séricas pré-operatórias de 25(OH)vitamina D não foram preditores de hipocalcemia pós-tireoidectomia total, enquanto o paratormônio pós-operatório influenciou a ocorrência dessa complicação.

ABSTRACT

SUMMARY Pseudohypoparathyroidism comprehends an assorted group of genetically rare disorders that share end-organ resistance to parathyroid hormone. Genetic and epigenetic modifications on guanine nucleotide-binding protein alpha-stimulating gene locus are the most common underlying mechanisms associated with pseudohypoparathyroidism. Biochemical and molecular analysis stratify pseudohypoparathyroidism into types 1A, 1B, 1C, and 2. We describe an unusual case of sporadic pseudohypoparathyroidism type 1B. A 34-year-old Caucasian woman was admitted to the emergency department, with persistent asthenia, limb paresthesias, and tactile hyposensitivity. Her physical examination, previous personal and family histories were unsuspicious, except for mild, intermittent and self-limited complaints of paresthesia during her two pregnancies, but no detailed workup was done. No typical features of Albright hereditary osteodystrophy were observed. The initial laboratory investigation showed elevated parathyroid hormone level (311.2 pg/mL), hypocalcemia (albumin-corrected serum calcium 4.3 mg/dL), hypocalciuria, hyperphosphatemia, hypophosphaturia, and vitamin D deficiency. Combined calcium, vitamin D, and magnesium supplementation was commenced, with symptomatic and analytical improvement. Albeit resolution of vitamin D deficiency, the patient relapsed with mild and intermittent lower limb paresthesias. Pseudohypoparathyroidism was confirmed by molecular identification of the 3-kb STX16 deletion. The treatment was readjusted, and one year later, symptomatic remission was attained. Clinical and biochemical features, and their respective course, along with lack of distinctive features of Albright hereditary osteodystrophy pointed to pseudohypoparathyroidism type 1B. A careful follow-up is needed to avoid complications and recurrence. Once correction of hypocalcemia and hyperphosphatemia is achieved, with no reported complications and recurrence, a good prognosis is anticipated, comparable to the general population.

ABSTRACT

Resumen Objetivo: Evaluar la asociación entre el valor de PTH medido a las 6 h posoperatorias de los pacientes sometidos a una tiroidectomía total, y la presentación de hipocalcemia en las primeras 24 h posoperatorias. Materiales y Método: Estudio analítico retrospectivo que utiliza una base de datos de 173 pacientes operados de tiroidectomía total entre enero de 2016 a diciembre de 2018 en el Hospital Militar de Santiago (HMS). Se revisaron datos demográficos y perioperatorios. Se utilizó curva ROC para evaluar la asociación entre PTH e hipocalcemia en nuestros pacientes. Resultados: 106 pacientes que cumplen criterios de inclusión. Promedio de PTH 30,5 (1,4-169), 58% presentó hipocalcemia, solo 17 pacientes fueron sintomáticos. PTH promedio en pacientes sintomáticos fue de 7,8 pg/ml. Curva ROC con área bajo la curva de 0,83 (0,75-0,92). Considerando valores útiles para la práctica clínica, una PTH menor a 6,3 (valor más bajo en nuestro laboratorio), tiene sensibilidad de 97%. El valor 18 de PTH (límite inferior del rango de normalidad del laboratorio) se obtiene 88,89% de sensibilidad con 66,07% de especificidad. Y con un valor de 47 pg/ml, se obtiene con un 91% de especificidad para predecir pacientes que no tendrían hipocalcemia. Conclusión: Con un valor de PTH disminuido bajo su valor normal, se puede decir que el riesgo de tener hipocalcemia es sobre el 80%, por lo que se debería iniciar tratamiento profiláctico y desistir del alta. En cambio, para definir un valor superior sobre el cual dar de alta precoz con seguridad, faltan más estudios.


Aim: To evaluate the association between PTH (parathormone) value measured at 6 hours postoperatively of patients submitted to total thyroidectomy, and the presentation of hypocalcemia in the first 24 hours. Materials and Method: Retrospective study of 173 patients with total thyroidectomy between January 2016 to December 2018 in HMS. Demographic and perioperative data were reviewed. The ROC curve was used to evaluate the association between PTH and hypocalcemia in our patients. Results: 106 patients meet inclusion criteria. Average of PTH 30.5 (1.4-169), 58% presented hypocalcemia, 17 patients were symptomatic. ROC curve with area under the curve of 0.83 (0.75-0.92) was obtained considering useful values for clinical practice, a PTH less than 6.3 (lowest value in our laboratory), has 97% sensitivity to predict hypocalcemia. If we use the value 18 we obtain 88.89% sensitivity with 66.07% specificity. And with a value of 47, it is obtained with 91% specificity to predict patients who would not have hypocalcemia Conclusion: With a PTH value decreased below its normal value, it can be said that the risk of having hypocalcemia is over 80%, so that prophylactic treatment should be initiated. To define a value on which to register early with security, more study is needed.

ABSTRACT

Introducción. La hipocalcemia posterior a tiroidectomía total es una complicación frecuente en la cirugía de tiroides. La hormona paratiroidea ha demostrado ser un predictor confiable para detectar los pacientes con alto riesgo de hipocalcemia significativa y la consecuente necesidad de administrar suplemento de calcio. El objetivo de este estudio fue determinar el tiempo óptimo de medición de la paratohormona para dicho fin. Métodos. Estudio prospectivo realizado en dos instituciones de nivel III en Popayán, Colombia, entre abril de 2016 y febrero de 2018, en el cual se midieron niveles de paratohormona prequirúrgico, a las 0, 2, 4 y 12 horas del postoperatorio, y se compararon con los valores obtenidos a los 3 meses de seguimiento en pacientes sometidos a tiroidectomía total. Se consideró como grupos de riesgo y con necesidad de suplemento de calcio un valor de paratohormona menor de 10 pg/ml o una disminución mayor del 80 % con respecto al valor prequirúrgico. Resultados. Se incluyeron 34 pacientes intervenidos. Tomando como umbral un valor menor de 10 pg/ml, la medición de paratohormona a las 4 horas fue sensible y específica (60 y 93,1 % respectivamente). Para una disminución mayor del 80 % con respecto al valor prequirúrgico, la sensibilidad fue del 60 % y la especificidad del 96,5 %, presentando un valor predictivo positivo de 75 % y negativo del 93,3 %, con una p < 0,001. Discusión. Una disminución mayor del 80 % del valor de paratohormona prequirúrgico medida a las 4 horas después de la tiroidectomía total permite identificar aquellos pacientes con alto riesgo de hipocalcemia significativa, que requieren administración temprana de suplementos de calcio, comparado con la determinación de la disminución a las 0, 2 y 12 horas postoperatorias


Introduction.Hypocalcemia after total thyroidectomy is a common complication in thyroid surgery.Parathyroid hormone has been shown to be a reliable predictor for detectingpatients with at high risk ofsignificant hypocalcemia and the consequent need for calcium supplementation. The objective of this study was to determine the optimal time for measuring parathormone for this purpose.Methods.Prospective study carried out in two level 3 institutions in Popayán, Colombia, between April 2016 and February 2018, in which levels of preoperative parathormone were measured at 0, 2, 4 and 12 hours postoperatively, and compared with the values obtained at 3 months of follow-up in patients undergoing total thyroidectomy. A parathormone value less than 10 pg/ml or a decrease greater than 80% with respect to the pre-surgical value was considered as risk groups and in need of calcium supplementation.Results. Thirty-four operated patients were included. Taking as a threshold a value of less than 10 pg/ml, the measurement of parathormone at 4 hours was sensitive and specific (60% and 93.1%, respectively). For a decrease greater than 80% with respect to the presurgical value, the sensitivity was 60% and the specificity was 96.5%, presenting a positive predictive value of 75% and a negative predictive value of 93.3% (p <0.001).Discussion.A decrease of more than 80% in the preoperative parathyroid hormone value measured at 4 hours after total thyroidectomy allows the identification of those patients at high risk of significant hypocalcaemia, who require early administration of calcium supplements, compared with the determination of the decrease at 0, 2 and 12 hours postoperatively

ABSTRACT

Resumen: Introducción: la hipovitaminosis D se encuentra ampliamente extendida a nivel mundial, con consecuencias clínicas a nivel óseo y extraóseo. Entre los factores que la causan se encuentran los antiepilépticos (AE). En Uruguay no se conoce su prevalencia en niños ni en pacientes que reciben AE. Objetivos: conocer la prevalencia de hipovitaminosis D de niños y adultos en un prestador de salud y compararla con la prevalencia en pacientes bajo tratamiento con AE. Método: estudio descriptivo, transversal, realizado entre marzo y diciembre de 2017. Las variables analizadas fueron: niveles de vitamina D, calcio, fósforo, fosfatasa alcalina y parathormona intacta. Se consideró insuficiencia de vitamina D niveles menores de 30 ng/ml y déficit niveles menores de 20 ng/ml. Resultados: se incluyeron 113 pacientes, 60 niños y 53 adultos. La prevalencia global de insuficiencia de vitamina D fue de 89% y déficit de 60%. En niños expuestos a AE, la media de vitamina D fue 17,5 ng/ml, y en niños no expuestos 19,6 ng/ml. En adultos la media de vitamina D fue de 18,1 en expuestos a AE y 16,9 en no expuestos. La diferencia de medias no fue estadísticamente significativa en niños ni en adultos. Se observaron niveles de calcemia significativamente descendidos en niños y adultos con AE. Conclusiones: la insuficiencia de vitamina D fue cercana a 90% y el déficit superó el 50%. No se encontraron diferencias significativas entre grupos en hipovitaminosis D, pero se observaron niveles de calcemia reducidos en los expuestos a AE. Es necesario continuar analizando los factores que la causan y sus consecuencias clínicas.


Summary: Introduction: hypovitaminosis D is a highly spread condition worldwide, with clinical consequences that affect bone directly, among other manifestations. Antiepileptic drugs are among factors that cause this deficiency. In Uruguay, there is no information about hypovitaminosis D in children or patients who receive antiepileptic drugs. Objectives: to learn about the prevalence of hypovitaminosis D in children and adults in a health institution and to compare it with the prevalence in patients receiving antiepileptic drugs. Method: descriptive, transversal study conducted from March through December, 2017. The following variables were analysed: vitamin D, calcium, phosphorous, alkaline phosphatase and intact parathyroid hormone. Vitamin D insufficiency was defined as vitamin D levels of less than 30 ng per mL and deficiency as D levels of less than 20 ng per mL. Results: 113 patients were included in the study, 60 of which were children and 53 adults. Global prevalence of vitamin D insufficiency was 89% and deficiency was 60%. In children taking antiepileptic drugs, the average vitamin D value was 17.5 ng/ml and it was 19.6 ng/ml for those not exposed to those drugs. In adults, the average vitamin D value was 18.1 in the population taking antiepileptic drugs and 16.9 in patients not taking that medication. The difference between average values was not statistically significant in children or adults. Calcemia levels observed were significantly lower in both children and adults taking antiepileptic drugs. Conclusions: vitamin D insufficiency was close to 90% and deficiency was over 50%. No significant differences were found between hypovitaminosis D groups, although reduced calcemia was observed in patients exposed to antiepileptic drugs. Further studies are necessary to analyse factors that cause this condition and its clinical consequences.


Resumo: Introdução: a hipovitaminose D está amplamente difundida em todo o mundo, com consequências clínicas a nível ósseo e extraósseo. Entre os fatores que a causam estão os medicamentos antiepilépticos (AE). No Uruguai, sua prevalência em crianças ou em pacientes adultos recebendo AE não é conhecida. Objetivos: conhecer a prevalência de hipovitaminose D em crianças e adultos em um prestador de serviços de saúde e compará-la com a prevalência em pacientes em tratamento com AE. Método: estudo transversal descritivo realizado entre março e dezembro de 2017. As variáveis analisadas foram: níveis de vitamina D, cálcio, fósforo, fosfatase alcalina e paratormona intacta. Níveis menores que 30 ng / ml e níveis de déficit menores que 20 ng / ml foram considerados como insuficiência de vitamina D. Resultados: foram incluídos 113 pacientes, 60 crianças e 53 adultos. A prevalência global de insuficiência de vitamina D foi de 89% e déficit de 60%. Em crianças expostas à AE, a média de vitamina D foi de 17,5 ng / ml e em crianças não expostas de 19,6 ng / ml. Em adultos, a média de vitamina D foi de 18,1 nos expostos ao AE e de 16,9 nos não expostos. A diferença nas médias não foi estatisticamente significativa nas crianças nem nos adultos. Níveis de cálcio significativamente diminuídos foram observados em crianças e adultos com EA. Conclusões: a insuficiência de vitamina D foi próxima a 90% e o déficit ultrapassou 50%. Não foram encontradas diferenças significativas entre os grupos na hipovitaminose D, mas níveis reduzidos de cálcio foram observados naqueles expostos a EA. É necessário continuar analisando os fatores que o causam e suas consequências clínicas.

ABSTRACT

Introducción: revisión narrativa que explica el panorama actual de la hipocalcemia y el hipoparatiroidismo como complicaciones de la tiroidectomía, su diagnóstico y tratamiento; con una descripción de las nuevas estrategias de prevención y tratamiento. Métodos: los motores de búsqueda utilizados fueron PubMed, Clinical Key, Embase, Cochrane y Lilacs, se incluyeron referencias en español e inglés, publicadas entre 2016 y 2020. Los artículos seleccionados se revisaron utilizando CONSORT, STROBE o PRISMA, según el caso. Resultados: fueron seleccionados 35 artículos que tenían relación directa con el tema, entre ellos: metanálisis, revisiones sistemáticas, estudios prospectivos y observacionales, revisiones narrativas y consensos de expertos, procedentes de los cinco continentes. La hipocalcemia y el hipotiroidismo en sus dos formas se relacionan con la afectación de la vascularización de las glándulas paratiroides o su exérecis accidental, existiendo factores predisponentes propios del paciente, derivados de la técnica quirúrgica o la característica patológica de la lesión en el tiroides. Como estrategias de prevención disponemos de herramientas ópticas para definir en el perioperatorio la disposición de las paratiroides; además existe la posibilidad de autotrasplantarlas al identificarlas en la pieza anatómica. El mejor marcador del estado metabólico del calcio es la PTHi. Conclusiones: la preservación de las paratiroides y de su irrigación es la mejor estrategia para prevenir los trastornos posoperatorios del calcio


Introduction: narrative review explaining the current picture of hypocalcemia and hypoparathyroidism as complications of thyroidectomy, describing new strategies employed for their diagnosis and treatment. Methods: searches in the PubMed, Clinical Key, Embase, Cochrane and Lilacs databases; references in Spanish and English, published between 2016 and 2020 were included. The selected articles were reviewed using CONSORT, STROBE or PRISMA, as appropriate. Results: 35 articles directly related with the topic were selected, including meta-analyses, systematic reviews, prospective and observational studies, narrative reviews and expert consensus, on all five continents. The two forms of hypocalcemia and hypoparathyroidism can result from devascularization or accidental removal of the parathyroid glands, patient-specific factors, or from the surgical technique or the pathological characteristics of the thyroid lesion. Preventive strategies include the use of optical tools for preoperative determination of parathyroid glands location; as well as the possibility of autotransplantation after confirming parathyroid tissue in the biopsy specimen. The best marker of calcium metabolism is iPTH. Conclusions: preservation of the parathyroid glands and their irrigation is the best strategy to prevent postoperative calcium disorders.

ABSTRACT

INTRODUCTION@#Dengue is one of the causes of morbidity and mortality among pediatric patients. Calcium has been shown to play a role in the myocardial function of the patient and is a potential cause of mortality among dengue patients. This study aimed to determine the accuracy of hypocalcemia in predicting the severity of dengue among pediatric patients.@*METHODS@#This is a systematic review and meta-analysis of published studies identified through an electronic literature search using PubMed/Medline, Cochrane Library, Herdin, Google Scholar, and hand search. Validity was assessed using the Cochrane risk of bias tool. Statistical analysis of the diagnostic test accuracy review was done using Review Manager 5.4.1 with the random effects model. Results showed sensitivity and specificity of hypocalcemia in severe dengue with a 95% confidence interval. The predictive values and likelihood ratios were also computed.@*RESULTS@#Four studies were analyzed. The mean serum total and ionized calcium levels of patients were decreased among the severe dengue group. Data showed that there is a 74% sensitivity (95% CI = 0.58, 0.84) and 75% specificity (95% CI = 0.67, 0.81) with a positive predictive value of 67% and a negative predictive value of 90.7%.@*CONCLUSION@#This systematic review and meta-analysis showed that hypocalcemia may be a useful tool to predict severe dengue fever. However, further analysis is needed to strengthen the the diagnostic accuracy of hypocalcemia.

ABSTRACT

In this study we evaluated the effects of the prepartum anionic diet on the electrolyte balance and calcemia of high producing dairy cows in the first days of lactation, and investigated the impact on the frequency of subclinical hypocalcemia (SCH). Sixty healthy Holstein cows, producing 30 kg of milk/day, handled in intensive system (compost barn), were distributed in groups (n=15) according to lactation order: first, second, third, and fourth to sixth. In the last three weeks before calving they received a diet with negative DCAD (-6mEq/100g DM) and high chloride content. After calving, they received a diet with positive DCAD (18mEq/100g DM). Urine pH was measured before calving. Serum Na+, Cl-, K+, and total Ca concentrations, and the strong ion difference (SID3) were determined in samples taken soon after calving (0h), 24, 48, 72 and 96h after. The frequencies of SCH were determined considering the critical value of 2.125mmol/L (8.5mg/dL). Two-way repeated measures ANOVA and chi-square test were used for comparisons. The cows eliminated acidic urine before calving. Na+, K+, Cl-, and SID3 values did not differ between groups. Na+ and K+ did not vary between days; Cl- was elevated at calving and decreased until 72h; and SID3 was reduced at calving and increased up to 48h. The Ca levels were reduced until 24h and increased up to 72h. Cows of third and fourth to sixth lactations presented lower values up to 24h. SCH was observed in almost half of the cows (43.3% to 55%) until 48h. The maintenance of hypocalcemia for three or more consecutive days occurred in 53.3% of third and fourth to sixth lactations cows. Ingestion of a high chloride prepartum anionic diet led to hyperchloremic acidosis and this imbalance was reversed on the second postpartum day. The induced effects on electrolyte and acid-base balances were not able to prevent the occurrence of SCH in the first days of lactation.(AU)


Os objetivos do estudo foram avaliar os efeitos que a dieta aniônica pré-parto provoca sobre o equilíbrio eletrolítico e sobre a calcemia de vacas leiteiras de alta produção nos primeiros dias de lactação, e verificar o impacto sobre a frequência da hipocalcemia subclínica (HSC). Sessenta fêmeas hígidas HPB, com produção de 30 kg de leite/dia, manejadas em sistema intensivo (compost barn), foram distribuídas por grupos (n=15) de acordo com a ordem de lactação: primeira, segunda, terceira e quarta a sexta. Nas três semanas pré-parto receberam dieta com DCAD negativa (-6mEq/100g MS) e teor de cloreto elevado. Após o parto receberam dieta com DCAD positiva (18mEq/100g MS). O pH da urina foi mensurado antes do parto. As concentrações séricas de Na+, Cl-, K+ e Ca total e a diferença de íons fortes (SID3) foram determinadas em amostras colhidas ao parto (0h), 24, 48, 72 e 96h após. As frequências de HSC foram determinadas considerando-se o valor crítico de 2,125mmol/L (8,5mg/dL). ANOVA de medidas repetidas e teste de qui-quadrado foram empregados para as comparações. As vacas eliminavam urina ácida antes do parto. Os valores de Na+, K+, Cl- e SID3 não diferiram entre os grupos. Na+ e K+ não variaram entre os dias; Cl- era elevado ao parto e diminuiu até 72h; e SID3 era reduzida ao parto e aumentou até 48h. A calcemia era reduzida até 24h e se elevou até 72h. Vacas de terceira e de quarta a sexta lactações apresentaram valores mais baixos até 24h. A HSC foi observada em quase metade das vacas (43,3% a 55%) até 48h. A manutenção de hipocalcemia por três ou mais dias seguidos ocorreu em 53,3% das vacas de terceira e de quarta a sexta lactações. A ingestão de dieta aniônica pré-parto com alto teor de cloreto provocou acidose hiperclorêmica e este desequilíbrio se reverteu no segundo dia pós-parto. Os efeitos induzidos sobre os equilíbrios eletrolítico e ácido base não foram capazes de prevenir a ocorrência de HSC nos primeiros dias da lactação.(AU)

ABSTRACT

SUMMARY INTRODUCTION: Obesity is a growing public health problem associated with many comorbid diseases. The aim of this study was to evaluate the relationship between body mass index and complications of thyroidectomy. METHODS: Patients who underwent total thyroidectomy between January 2015 and December 2018 were enrolled. Patients were divided into two groups, i.e., BMI <25 (group A) and BMI≥ 25 (group B). Demographics, operative time, and complications were retrospectively reviewed. RESULTS: The study included 145 patients (66 in Group A and 79 in Group B). There was no significant difference between the two groups in terms of age (p=0.330) and gender (p=0.055). No surgical site infection and bleeding complications were observed in any patients. The mean operative time was 148.4 minutes (90-235) in Group A and 153.4 minutes (85-285) in Group B (p=0.399). Transient hypocalcemia was observed in 25 (37.9%) patients in group A, and 23 (29.1%) patients in Group B (p = 0.291). Permanent hypocalcemia was not observed in any patient in group A, and in 2 patients in Group B (2.5%) (p = 0.501). Transient recurrent nerve palsy was observed in 1 (1.5%) patient in Group A and in 3 (3.8%) patients in Group B (p=0.626). None of the patients had permanent recurrent nerve palsy. Parathyroid autotransplantation was performed on 1 patient (1.5%) in group A and on 7 (8.9%) patients in Group B (p=0.055). CONCLUSION: We think there is no relationship between a high BMI and thyroidectomy complications, and surgery can also be performed safely in this patient group.


RESUMO INTRODUÇÃO: A obesidade é um crescente problema de saúde pública associado a muitas doenças comórbidas. O objetivo deste estudo foi avaliar a relação entre o índice de massa corporal e as complicações da tireoidectomia. MÉTODOS: Os pacientes submetidos a tireoidectomia total entre janeiro de 2015 e dezembro de 2018 foram incluidos. Os pacientes foram divididos em dois como IMC <25 (grupo A) e IMC . 25 (grupo B). Demografia, tempo operatorio e complicacoes revisadas retrospectivamente. RESULTADOS: O estudo incluiu 145 pacientes (66 no grupo A e 79 no grupo B). Não houve diferença significativa entre os dois grupos em termos de idade (p = 0,033) e sexo (p = 0,055). Nenhuma infecção do sítio cirúrgico e complicações hemorrágicas foram observadas em nenhum paciente. O tempo operatório médio foi de 148,4 minutos (90-235) no grupo A e 153,4 minutos (85-285) no grupo B (p = 0,399). Hipocalcemia transitória foi observada em 25 (37,9%) pacientes do grupo A e 23 (29,1%) do grupo B (p = 0,291). Hipocalcemia permanente não foi observada em nenhum paciente do grupo A e em 2 pacientes do grupo B (2,5%) (p = 0,501). Paralisia nervosa recorrente transitória foi observada em 1 (1,5%) paciente no grupo A e em 3 (3,8%) pacientes no grupo B (p = 0,626). Nenhum dos pacientes apresentou paralisia nervosa recorrente permanente. O autotransplante de paratireóide foi realizado em 1 paciente (1,5%) no grupo A e em 7 (8,9%) pacientes no grupo B (p = 0,055). CONCLUSÃO:: Acreditamos que não há relação entre um IMC alto e as complicações da tireoidectomia e a cirurgia pode ser realizada com segurança também neste grupo de pacientes.
