Trastorno de identidad de género. Parte II: terapia endocrinológica en el proceso de readecuación corporal / Gender identity disorder. Part II: endocrine therapy in the process of body readjustment

Endocrinology step of transgender readjustment therapy is made according to previously published in the part 1 of article: “gender identity disorder in rev. chil. endocrinol. diabetes 2015, 8 (4): 167-173.During started puberty in Tanner stage 2-3, the persistence of the experience that their identity male or female gender is not coherent with its bodily, authorize to start the endocrinological therapy, as an important step of body readjusting. In the process of transition from male to female or female to male, should stop pubertal development, what we do with GNRH analogues: intramuscle leuprolideor triptorelin 11.25 mg. every 12 weeks or with medroxyprogesterone acetate 150 mg. monthly. This process continues until 16 years, adding antiandrogen, preferably spironolactone in the process of body readjusting of male to female. At 16 years old, starts the cross hormonal therapy to masculinizing or feminizing. Maintaining gonadotrophin suppression, female to male, testosterone undecanoate or other injectable testosterone esters is administered, customizing the date of administration and inMale to female, daily use of oral estradiol valerate or transdermal gel. Plasma levels of estradiol andtestosterone should not be located in high or supraphysiological range to avoid thromboembolism or polycythemia risk in those who receive testosterone. Should to be explained the time to obtain the bodily effects, achieving a realistic attitude of the goals and the need for regular checks. Attendance to emotional changes, mainly to meet the social gender role. The laboratory, metabolic, hormonal, hemogram and electrolytic changes are evaluated. To be indicated bone densitometry and study images of internal genitals and breasts are necesary...

Vigilancia de tuberculosis en el Servicio de Salud Viña del Mar-Quillota entre los años 1999-2008: estudio longitudinal de tendencia / Surveillance of Tuberculosis in Health Service of Viña del Mar-Quillota, Chile from 1999 to 2008

Trend in Tuberculosis (TB) rates and association of factors affecting the outcome of this disease were assessed in the Health Service of Viña del Mar-Quillota, Chile from 1999 to 2008. Study of 1291 TB patients by the years 1999 to 2008. We evaluated incidence and mortality rate per 100,000 inhabitants, pulmonary / extrapulmonary ratio, presence of HIV, death and site of infection. It was found a decreasing trend in the incidence rate (p < 0.001 R² = 0.97) and association between the presence of HIV and case fatality rate (p < 0.001). It was not found association between site of disease and mortality rate (p = 0.3) nor a decreasing trend in mortality (p = 0.116) and pulmonary/extrapulmonary ratio (p = 0.194). There is a decreasing trend in the incidence rate of TB patients which reflects a well-functioning system of control and surveillance; the presence of HIV is associated with death because of this it should be considered in clinical management of TB.

Se evalúa la tendencia de las tasas de incidencia de tuberculosis (TBC) y de factores asociados al desenlace de esta enfermedad, en el Servicio de Salud Viña del Mar-Quillota durante los años 1999 2008. Estudio de 1.291 pacientes con TBC entre los años 1999-2008. Se evalúa tasa de incidencia y mortalidad por 100.000 habitantes, razón de casos pulmonares/extrapulmonares, presencia de VIH, tasa de letalidad y localización de la infección. Se observa una tendencia decreciente en la tasa de incidencia (p <0,001; R² = 0,97) y asociación entre presencia de VIH y fallecer (p < 0,001). No se observa asociación entre localización de la enfermedad y fallecimiento (p = 0,3), ni tendencia decreciente en la tasa de mortalidad (p = 0,116) ni en la razón de casos pulmonares/extrapulmonares (p = 0,194). La tendencia decreciente de la tasa de incidencia de TBC refleja un buen funcionamiento del sistema de control y vigilancia. La infección por VIH se asocia con mayor riesgo de muerte por lo que debe considerarse en el enfrentamiento clínico de la TBC.

Síndrome de carcinoide con manifestación inicial a nivel valvular cardíaco: a raíz de un caso clínico / Carcinoid syndrome presenting as valvular diseas: report of one case

Carcinoid syndrome is observed in one third of carcinoid tumors and usually appears when there are liver metastases. One of the main complications of this syndrome is the appearance of tricuspid or pulmonary valvular disease. We report a 56 years old male presenting with malaise and a weight loss of 10 kg. On physical examination, a heart murmur suspicious of a double tricuspid lesion was found. The echocardiogram was suggestive of a carcinoid valvular disease. The abdominal CAT scan showed a small bowel tumor. Urinary 5-hydroxy-indol- acetic acid values were highly elevated. The patient was subjected to excision of the distal ileum, liver metastasectomy and hemicolectomy. The pathological study of the surgical piece confirmed the diagnosis of carcinoid tumor. Two years after surgery, the patient is in stable conditions.

Asociación entre infección por virus de la Hepatitis B y Poliarteritis nodosa / Association between Hepatitis B virus infection and Polyarteritis Nodosa

Introducción: la Poliarteritis nodosa (PAN) se define como una vasculitis necrotizante que compromete a las arterias de mediano calibre, y causa un compromiso sistémico. Existe una asociación entre la PAN y la infección por el virus de la Hepatitis B, en relación principalmente con el depósito de inmunocomplejos virales circulantes. Las manifestaciones clínicas son inespecíficas y requiere un alto índice de sospecha. Se han usado varios regímenes de inmunosupresores (corticoides-ciclofosfamida) plasmaféresis y drogas antivirales, con respuestas variables. Objetivo: presentación de un caso clínico de PAN asociado con infección por virus de Hepatitis B, y revisión de la literatura. Caso clínico: paciente masculino de 40 años, con manifestaciones severas de Poliartritis nodosa, asociado con infección por Hepatitis B. Conclusiones: la PAN es una enfermedad poco frecuente, la asociación con infección por Hepatitis B está bien documentada y las estrategias terapéuticas difieren de las de la PAN clásica. Es una patología potencialmente fatal cuando no se reconoce y trata adecuadamente

Backgraound: Polyarteritis nodosa (PAN) is defined by a necrotizing vasculitis of medium sized arteries that causes a systemic inflammatory disease. There is an association between PAN and hepatitis B virus (HBV) infections, related mostly with viral circulting immune complexes. Clinical manifestations are not specific and require a high index of suspicion. Several immunosuppressive regimens (corticoids-ciclophosphamide), plasmapheresis and antiviral drugs have been used with varying response. Objective: Report of a clinical case of PAN associated with Hepatitis B virus infection and review of the literature. Case-reporte: A 40 year old man with severe manifestations of Polyarteritis nodosa, associated with Hepatitis B infection. Conclusions: PAN is uncommon disease, the association with hepatitis B virus infection is well documented, and the treatment strategies differs from the classic PAN. It is a potentially fatal disease when unrecognized and untreated

Osteomalacia hipofosfatémica secundaria a sarcoma de muslo: caso clínico / Hypophosphatemic osteomalacia secondary to a sarcoma: report of one case

Tumor induced osteomalacia is uncommon and is characterized by an isolated and not PTH dependent reduction in tubular phosphate reabsorption. This alteration is produced by phosphaturic factors, such as fibroblast growth factor-23 (FGF-23) that are secreted by tumors. We report a 41 years old female presenting with joint pain and progressive loss of muscle strength in the lower limbs. Initial laboratory assessment showed hypophosphatemia, elevated alkaline phosphatases, normal intact parathormone levels, low levels of 25 hydroxy vitamin D and an elevated 24 h phosphaturia. Bone mineral density showed spine and femoral neck osteopenia. A positron emission tomography (PET) revealed a right thigh tumor with lung metastases. Its biopsy disclosed a fibrosarcoma. FGF-23 levels, measured by ELISA were markedly elevated. The patient was discharged with palliative measures.

Riesgo obstétrico y perinatal en embarazadas mayores de 35 años / Perinatal risk in pregnant women of 35 years and older

Antecedentes: El embarazo en edades tardías es una condición que ha aumentado en los últimos años. Objetivo: Evaluar el riesgo materno y perinatal en embarazadas mayores de 35 años. Método: Estudio de cohorte retrospectiva de todos los embarazos atendidos en el hospital Dr. Gustavo Fricke de Viña del Mar, entre enero de 2001 y diciembre de 2006. Se excluyeron menores de 20 años. Se analizaron variables maternas y perinatales. Resultados: En el período hubo 16.338 partos, 10,9 por ciento fueron en mujeres entre 35 y 39 años y 3,6 por ciento en embarazadas de 40 años o más. Un 27,2 por ciento de los embarazos fue en primigestas. La comparación entre embarazadas de 20-34 años y de 35-39 años mostró mayor frecuencia de hipertensión arterial crónica, hospitalización durante el embarazo, diabetes, preeclampsia, hemorragia del tercer trimestre, parto cesárea, hemorragia puerperal, menor peso del recién nacido, y defectos congénitos, entre otros. Hubo mayor frecuencia de rotura prematura de membranas al analizar las mayores de 40 años. Las primigestas tuvieron mayor frecuencia de obesidad, preeclampsia, diabetes, hospitalización del recién nacido, y hemorragia puerperal. Al realizar una regresión logística para determinar influencia de la edad, se apreció que el riesgo de comorbilidades y eventos adversos maternos y fetales aumentaba proporcionalmente con la edad. Conclusión: La edad materna se asoció significativamente en forma independiente con resultados maternos y perinatales adversos. Hubo mayor riesgo para la mayoría de las variables analizadas en embarazadas de 35 años o más.

Background: Pregnancy in elderly ages is a condition that has been rising in the last years. Objective: To evaluate the maternal and perinatal risk of pregnant over the 35 years-old. Methods: Retrospective cohort study of all pregnant women attended in Dr. Gustavo Fricke Hospital, Viña del Mar, from January 2001 to December 2006. Patients under 20 years were excluded. Maternal and perinatal variables were analyzed. Results: 16,338 childbirths were analyzed, 10.9 percent were in women between 35 and 39 years, and 3.6 percent in women of 40 years or more. A 27.2 percent of the pregnancy was the first gestation. A greater frequency of chronic hypertension, hospitalization during pregnancy, diabetes, preeclampsia, third trimester hemorrhage, cesarean section, postpartum hemorrhage, low birth weight, and congenital defects, among others, were found when comparing pregnant of 20-34 years-old with pregnant of 35-39 years-old. Elevated frequencies of premature rupture of fetal membranes were found in women over 40 years. First gestation women had higher frequency of obesity, preeclampsia, and hospitalization during pregnancy, diabetes and postpartum hemorrhage. Using logistic regression to determinate the influence of age, we determine that the risk of co morbidity and maternal and fetal adverse events, increase according to age. Conclusion: Maternal age was associated independently and significantly with adverse maternal and perinatal results. Major risk was observed for the majority of the variables analyzed in pregnant of 35 years or more.

Aumento del daño en el ADN y estrés oxidativo en espermatozoides de pacientes con oligozoospermia idiopática y antecedentes de criptorquidismo / Extent of sperm DNA damage in spermatozoa from men examined for infertility. Relationship with oxidative stress

Background: Cryptorchidism and oligozoospermia are clinical conditions closely associated with impaired fertility. Oxidative stress and related sperm DNA damage have been identified as significant causes of male infertility. Aim: To determine the extent of sperm nuclear DNA damage in patients affected with idiopathic oligozoospermia or undescended testes and to examine its relationship with oxidative stress. Patients and methods: We studied 20 patients with idiopathic oligozoospermia and 18 with undescended testes (who previously underwent orchiopexy) and 25 normozoospermic healthy controls. All subjects underwent semen analysis. Sperm DNA damage was evaluated by the sperm chromatin structure assay/flow cytometry (SCSA-FCM) and by the dUTP-biotin nick end labeling (TUNEL) assay. Levels of reactive oxygen species (ROS) and total antioxidant capacity (TAC) were assessed by a chemiluminescence assay. Results: DFI (percentage of sperm with denatured DNA) values and percentage of TUNEL positive cells were significantly greater in patients with oligozoospermia (DFI: 28.8±5.6; TUNEL+: 26.9±3.0) or cryptorchidism (DFI: 26.4±10.1; TUNEL+: 29.1±3.9), compared with controls (DFI: 7.1±0.9; TUNEL+: 14.2±1.2). Similarly, both groups of patients had significantly higher (p <0.01) levels of ROS. TAC levels did not differ between control and patient groups, suggesting that the DNA damage occurs before spermiation. Conclusions: Sperm DNA damage is significantly increased in men with idiopathic oligozoospermia and in cryptorchid subjects. The finding of increased ROS levels may indicate that seminal oxidative stress may be involved in the pathogenesis of sperm DNA damage in these patients.

Histerectomía obstétrica en el Hospital de Puerto Montt, 2000-2005 / Obstetric hysterectomy in the Puerto Montt Hospital, 2000-2005

Se presenta la revisión de 25 pacientes con histerectomía obstétrica (HO) periparto ocurridas en el Hospital de Puerto Montt en el período 2000 - 2005. En 24 casos (96 por ciento) el parto fue por operación cesárea. El riesgo de HO periparto es 56 veces mayor en los partos cesárea que en los partos vaginales. Las principales causas de interrupción fueron cicatriz de 2 o más cesáreas en las cesáreas electivas y en las cesáreas urgentes la metrorragia del tercer trimestre. La principal causa clínica de HO es el acretismo placentario en 12 casos (48 por ciento) seguido de atonía uterina en 8 casos (32 por ciento). El estudio histológico se hizo en el 76 por ciento de los casos de los cuales el 80 por ciento confirma acretismo placentario. La HO total se realizó en 13 casos (52 por ciento) y subtotal en 12 casos (48 por ciento). El tiempo operatorio promedio fue de 124,3 + - 37,8 minutos. El hematocrito post operatorio tiene un descenso menor en las pacientes con HO subtotal que en la total (p< 0,05). La principal complicación fue la lesión vesical, que ocurrió en mayor proporción en el grupo de la HO total versus la subtotal (3:1), sin diferencias significativas. No se registró muerte materna asociadas a HO; hubo 4 muertes neonatales, 3 en relación a sufrimiento fetal agudo por metrorragia del tercer trimestre y 1 por infección ovular.

Hiperparatiroidismo primario con compromiso esquelético grave: Un caso de carcinoma paratiroideo / Primary hyperparathyroidism with severe skeletal involvement in one patient with parathyroid carcinoma

Parathyroid carcinoma is an uncommon cause of primary hyperparathyroidism; however, when this condition is severe, cancer must be suspected. We report on a 28-year-old male with severe hypercalcemia, cachexia, acute pancreatitis, urolithiasis, anemia and a severe skelletal involvement with multiple fractures. The patient had a 4-cm parathyroid tumor, that was surgically excised, along with the ipsilateral thyroid lobe. During the postoperative period, he had a severe and prolonged hungry bone syndrome, with a slow recovery of fractures, with functional and anatomical sequelae in the extremities. PTH levels were adequate for the serum calcium during the 16 months of follow-up.

Cortisol y dehidroepiandrosterona nocturnos como marcadores pronósticos en pacientes críticos / Nocturnal cortisol and dehydroepiandrosterone like prognostic markers in critical patients

El cortisol plasmático guarda correlación con la severidad y duración del estado crítico, y el papel de la Dehidroepiandrosterona sulfato (DHEA-S) no ha sido identificado claramente. El paciente crítico muestra una activación máxima inicial del eje suprarrenal, si la situación crítica se prolonga, se puede producir una insuficiencia suprarrenal relativa. Midiendo cortisol y DHEA-S durante la noche de las 24 primeras horas críticas se podría hacer más evidente esta insuficiencia resultando una mejor correlación entre estas hormonas, APACHE II y mortalidad. Diseño: Estudio observacional en pacientes críticos de la UTI del Hospital de Urgencia Asistencia Pública. Cuarenta y ocho (48) pacientes (30 hombres y 18 mujeres) sin antecedentes de: insuficiencia suprarrenal, uso de fenitoína, anticonvulsivantes, rifampicina, ketoconazol, corticosteroides, síndrome de Cushing, patología pituitaria, daño hepático crónico, insuficiencia renal crónica, alcoholismo activo crónico o readmisiones. EL APACHE II fue evaluado al ingreso. Cortisol y DHEA-S fueron medidos a las 00.00 de las primeras 24 h de su ingreso a UTI. Resultados: EL APACHE II (25,1±6,7 contra 16,3±7, p=0,001) y edad (59,5±15,8 contra 44,4±18,1, p 0,011) fueron significativamente más elevados en los fallecidos. En los fallecidos el cortisol mostró una tendencia a niveles más elevados. El DHEA-S mostró niveles considerablemente más altos en los sobrevivientes (5450,9±3824,0 contra 2980,3±2159,3 p= 0,03) junto como el índice DHEA-S/cortisol (12,66±14,19 contra 3,91±4,06, p= 0,004). Conclusiones: La tendencia a niveles más altos de cortisol nocturno observado en las 24 primeras horas induce para pensar que la insuficiencia suprarrenal relativa no desempeñaría un papel en las 24 primeras horas del estado crítico. Los niveles de DHEA-S y el índice DHEA-S/Cortisol son marcadores de sobrevida en nuestra población estudiada.

We hope, based on our review, to desing and to excuse more powerful studies and programs aimed to help in the solution to this problem.

Estado de salud periodontal en diabéticos tipo 1, de 18 a 30 años de edad, de Santiago de Chile / Periodontal disease in Chilean type I diabetic patients between 18 and 30 years old

Background: The prevalence of periodontal diseases, gingivitis and periodontitis, is higher in diabetic patients and can have severe functional and esthetic consequences early in their lives. Aim: To evaluate the prevalence of periodontal disease in type 1 diabetics, aged between 18 and 30 years old, living in Santiago de Chile. Subjects and methods: One hundred male and female type 1 diabetics were examined. Glycated hemoglobin A1c, microalbuminuria, and fundoscopy were assessed in a sample of 52 subjects, separated in two groups according to the presence of periodontal disease. Results: The prevalence of gingivitis was 22 percent, periodontitis 41 percent. Only 37 percent of subjects were free of periodontal disease. When compared with patients without periodontal disease, in the group of patients with the disease there was a higher proportion of subjects with diabetes lasting more than 10 years (28 and 55 percent respectively) and a higher proportion of patients with chronic complications of diabetes (42 and 58 percent respectively). Conclusions: A high prevalence of periodontal diseases was observed in this sample of diabetic patients. A long history of diabetes and the presence of chronic complications were risk factors for these diseases in the analyzed sample

Tratamiento del hirsutismo con espironolactona y con espironolactona más dexametasona / Treatment of hirsutism with spironolactone and with spironolactone plus dexamethasone

Background: Spironolactone has an anti androgenic effect, inhibiting the binding of androgens to their receptor. This antagonistic effect is the basis for the use of spironolactone in the treatment of hirsutism. Aim: To study the effectiveness and safety of spironolactone in the treatment of hirsute women and of the association of spironolactone plus dexamethasone in the treatment of hirsutism with glucocorticoid sensitive hyperandrogenism. Patients and method: Sixteen women (group 1) with peripheral hirsutism (defined as those with normal androgens levels, normal menstrual cycles and ovulation) and 24 women (group 2) with glucocorticoid sensitive hyperandrogenic hirsutism were studied. Group 1 was treated with spironolactone 50 mg bid and group 2 with same spironolactone dose plus dexamethasone 0.5 mg at 23 h during one month and 0.25 mg thereafter. Patients were followed during one year. Results: After one year of treatment, a 54 percent reduction in Moncada hirsutism escore was observed in group 1 and 52 percent reduction in group 2. Observed secondary effects of spironolactone were increases in diuresis, fatigability, acne aggravation and seborrhea in two patients. Two additional patients had spotting. No secondary effect attributable to glucocorticoid use were observed. Conclusions: Spironolactone is effective and safe in the treatment of hirsutism. Androgenic supression did no increases its effectiveness, underscoring the peripheral anti androgenic activity os spironolactone

Validez de la medición rutinaria del calcio sérico / Assessment of rutinary serum calcium measurement

Subjects and methods: Serum calcium was measured in 731 subjects participating in a preventive medical examination, using an automated colorimetric method. Serum albumin was also measured. In 31 randomly chosen serum samples, calcium was also measured by atomic absorption spectrometry. Normal serum calcium ranges were established as the mean ñ 1.34 SD of the sample. Results: Mean serum calcium was 9 ñ 0.7 mg/dl, serum albumin was 4.3 ñ 0.5 g/dl and albumin corrected calcium levels were 8.7 ñ 0.7 mg/dl. Excluding lipemic sera, colorimetric calcium measurement had a correlation of 6.0 with atomic absorption spectrometry and a reliability of 17.9 percent. Using the proposed normal ranges (7.3 - 10.6 mg/dl), the frequency of hypercalcemia and hypocalcemia was 0.14 and 0.4 percent respectively. Conclusions: Most subjects found to have hyper or hypocalcemia in this study were asymptomatic
