Systemic Hormonal Unloading (SHU) in secondary hypertension: Addressing the long-term adverse cardiovascular outcomes

@#Excess hormone production from adrenal tumors caused by primary hyperaldosteronism or pheochromocytoma are common etiologies for secondary hypertension. Studies have shown that sustained long-term circulating hormones in excess affect the blood vessels and cardiac structures. Inflammation of cardiomyocytes leads to fibrosis and eventual cardiomyopathy and is clinically presented as arrhythmia, nonfatal myocardial infarction, heart failure, or even death. The tissue changes and/or impaired cardiac function are reversible if early diagnosis and removal of the adrenal tumor by unilateral adrenalectomy is done. However, the condition becomes challenging if the adrenal lesions are bilateral. This article introduces the concept of systemic hormonal unloading and will discuss the philosophy of quality of life in managing bilateral adrenal disease.

Influencing factors of survival of patients with airway stenosis requiring clinical interventions after lung transplantation / 器官移植

Objective To analyze the influencing factors of survival of patients with airway stenosis requiring clinical interventions after lung transplantation. Methods Clinical data of 66 patients with airway stenosis requiring clinical interventions after lung transplantation were retrospectively analyzed. Univariate and multivariate Cox’s regression models were adopted to analyze the influencing factors of survival of all patients with airway stenosis and those with early airway stenosis. Kaplan-Meier method was used to calculate the overall survival and delineate the survival curve. Results For 66 patients with airway stenosis, the median airway stenosis-free time was 72 (52,102) d, 27% (18/66) for central airway stenosis and 73% (48/66) for distal airway stenosis. Postoperative mechanical ventilation time [hazard ratio (HR) 1.037, 95% confidence interval (CI) 1.005-1.070, P=0.024] and type of surgery (HR 0.400, 95%CI 0.177-0.903, P=0.027) were correlated with the survival of patients with airway stenosis after lung transplantation. The longer the postoperative mechanical ventilation time, the higher the risk of mortality of the recipients. The overall survival of airway stenosis recipients undergoing bilateral lung transplantation was better than that of their counterparts after single lung transplantation. Subgroup analysis showed that grade 3 primary graft dysfunction (PGD) (HR 4.577, 95%CI 1.439-14.555, P=0.010) and immunosuppressive drugs (HR 0.079, 95%CI 0.022-0.287, P<0.001) were associated with the survival of patients with early airway stenosis after lung transplantation. The overall survival of patients with early airway stenosis after lung transplantation without grade 3 PGD was better compared with that of those with grade 3 PGD. The overall survival of patients with early airway stenosis after lung transplantation treated with tacrolimus was superior to that of their counterparts treated with cyclosporine. Conclusions Long postoperative mechanical ventilation time, single lung transplantation, grade 3 PGD and use of cyclosporine may affect the survival of patients with airway stenosis after lung transplantation.

Chronic Bi-Maxillary Osteomyelitis Caused by Actinomycetes in a Patient with Severe COVID-19 / Osteomyelitis bi-maxilar crónica causada por Actinomycetes en un paciente con COVID-19 severo

Abstract Osteomyelitis is defined as the inflammation of the either medullary, cortical, or cancellous bone, including nerves and blood vessels, causing necrosis and bone sequestrum formation; this condition has become a rare pathology, and odontogenic infections are considered the most frequent causal factor. This case shows a patient with bi-maxillary osteomyelitis caused by Actinomyces spp, which was worsened for severe COVID-19 infection. Patient was submitted at surgery as, amplified total bilateral maxillectomy through the surgical technique Weber-Fergusson, and prolonged use of combination of antibiotics, achieved a good recovery. Two years later follow- up, the patient no show imaging or clinical evidence of the infection of osteomyelitis. The present case shows an interesting relationship between a rare infection and its association with COVID-19.

Resumen La osteomielitis se define como la inflamación del hueso medular, cortical o esponjoso, incluyendo nervios y vasos sanguíneos, causando necrosis y formación de secuestro óseo; esta condición es una patología rara, y las infecciones odontogénicas son consideradas como el factor causal más frecuente. En este caso, se muestra un paciente con osteomielitis bi-maxilar causada por Actinomyces spp, la cual empeoró por la infección de COVID-19 severo. El paciente fue sometido a una cirugía, maxilectomía bilateral total amplificada, a través de la técnica quirúrgica de Weber- Fergusson, y el uso prolongado de una combinación de antibióticos, logrando una buena recuperación. A los 2 años de seguimiento, el paciente no mostró evidencia clínica o imagenológica de la infección de osteomielitis. El presente caso muestra una interesante relación entre una infección rara y su asociación con COVID-19.

Menopausia quirúrgica en pacientes con mutación BRCA, el papel de la terapia hormonal / Surgical Menopause in Patients with BRCA Mutation, the Role of Hormone Therapy

Introducción: las mujeres con mutación BRCA1/2 (mBRCA) tienen un riesgo aumentado de desarrollar cáncer de mama (CM) y ovario (CO). La salpingo-oforectomía bilateral (SOB) se asocia con la reducción del riesgo del 80% para CO y un 50% para CM. Se recomienda realizarla entre los 35 y 40 años. Como consecuencia se produce una menopausia prematura, con un impacto negativo sobre la calidad de vida por la presencia de síntomas climatéricos, aumento del riesgo de enfermedad cardiovascular, osteoporosis y riesgo de alteración cognitiva. La terapia hormonal (THM) es el tratamiento más eficaz para la prevención de estos síntomas. Estado del arte: distintos estudios han demostrado un mayor riesgo de CM en mujeres posmenopáusicas que reciben THM en particular con terapia combinada, estrógeno + progesterona (E+P). Según el metanálisis de Marchetti y cols., en las mujeres portadoras de mBRCA que recibieron THM, no hubo diferencias en el riesgo de CM comparando E solo con E+P. En el estudio de Kotsopoulos, incluso se encontró un posible efecto protector en aquellas que usaron E solo. Otro estudio en portadoras sanas demostró que, en las mujeres menores de 45 años al momento de la SOB, la THM no afectó las tasas de CM. Sin embargo, en las mujeres mayores de 45 años, las tasas de CM fueron más altas. Como el esquema de E+P se asocia con un mayor riesgo relativo (RR) de CM, las dosis de progestágenos utilizados se deberían limitar, eligiendo derivados naturales de progesterona, de uso intermitente para disminuir la exposición sistémica. Según diferentes guías internacionales, a las portadoras de mBRCA sanas que se someten a una SOB se les debe ofrecer THM hasta la edad promedio de la menopausia. Conclusión: la menopausia prematura disminuye la expectativa de vida; es por ello que una de las herramientas para mejorar y prevenir el deterioro de la calidad de vida es la THM. El uso de THM a corto plazo parece seguro para las mujeres portadoras de mBRCA que se someten a una SOB antes de los 45 años, al no contrarrestar la reducción del riesgo de CM obtenida gracias a la cirugía.

Introduction: women with BRCA1/2 (mBRCA) mutation have an increased risk of developing breast (BC) and ovarian (OC) cancer. Bilateral salpingo-oophorectomy (BSO) is associated with an 80% risk reduction for OC and 50% for BC. The recommended age for this procedure is 35 to 40 years. The consequence is premature menopause, which hurts the quality of life due to the presence of climacteric symptoms, increased risk of cardiovascular disease, osteoporosis, and a higher risk of cognitive impairment. Hormone therapy (MHT) is the most effective treatment for preventing these symptoms. State of the art: different studies have shown an increased risk of BC in postmenopausal women receiving MHT, particularly with combined therapy, estrogen + progesterone (E+P). According to the meta-analysis by Marchetti et al., in women carrying mBRCA who received MHT, there was no difference in the risk of BC compared to E alone with E+P. In the Kostopoulos study, there was also a possible protective effect in those who used E alone. Another study in healthy carriers showed that in women younger than 45 years at the time of BSO, MHT did not affect BC rates. However, in women older than 45 years, BC rates were higher. As the E+P scheme is associated with a higher RR of BC, the doses of progestogens should be limited, choosing natural progesterone byproducts of intermittent use to decrease systemic exposure. According to various international guidelines, healthy mBRCA carriers undergoing BSO should be offered MHT until the average age of menopause. Conclusion: premature menopause decreases life expectancy, which is why one of the tools to improve and prevent deterioration of quality of life is MHT. Short-term use of MHT appears safe for women with mBRCA who undergo BSO before age 45 as it does not counteract the reduction in the risk of MC obtained by surgery. (AU)

Bilateral Variation of the Vertebral Artery: Report of a Case and its Clinical Implication / Variación Bilateral de la Arteria Vertebral; Reporte de un Caso y su Implicancia Clínica

SUMMARY: There are many reports on anatomical variations of the vertebral arteries, which may be related to origin, trajectory, caliber, and side. Bilateral variations are less frequent, however, and less common are bilateral variants that differ from each other. The aim of this work was to report the presence of a bilateral variation of the vertebral artery and its functional and clinical implications. Dissection of a female cadaver, fixed in 10 % buffered formaldehyde, which had not undergone any previous surgeries in the study area and had anatomical variations in both vertebral arteries. In each one, follow-up was done from its origin to its end, determining its trajectory, diameters, branching, and anatomical relations. A left vertebral artery was found, starting in the aortic arch and making a sinuous trajectory of 4 curvatures to enter the transverse foramen of C4. The right vertebral artery began as the first branch of the subclavian artery. Its initial trajectory was rectilinear, followed by a right concave curve, a 360° loop that included a second ascending curve, and ended straight before entering the transverse foramen of C6. The coexistence of bilateral variations in the vertebral arteries is possible. This atypical situation can potentially generate vascular and neurological pathologies, but with different symptoms and causes. Knowing these variations and deliberately searching for them will enable the specialist to make a suitable differential diagnosis.

Existen múltiples reportes sobre variaciones anatómicas de las arterias vertebrales, las que se pueden relacionar con origen, trayecto, calibre y lateralidad. Sin embargo, las variaciones bilaterales son menos frecuentes, y menos común es que las variantes bilaterales sean diferentes entre ellas. El objetivo de este trabajo fue reportar la presencia de una variación bilateral de la arteria vertebral y su implicancia funcional y clínica. Disección en un cadáver de sexo femenino, fijado en formaldehido tamponado al 10 %, el cual no presentaba intervenciones quirúrgicas previas en la región de estudio y que tenía variaciones anatómicas en ambas arterias vertebrales. En cada una se realizó seguimiento desde su origen hasta su terminación, pudiendo determinar su trayecto, diámetros, ramificaciones y relaciones anatómicas. Se encontró una arteria vertebral izquierda originada en el arco aórtico, que realizaba un trayecto sinuoso de 4 curvaturas e ingresaba al foramen transverso de C4. La arteria vertebral derecha se originaba como primera rama de la arteria subclavia. Su trayecto inicial era rectilíneo seguido por una curva de concavidad derecha, un loop (giro) de 360° que incluía una segunda curva ascendente y terminaba en dirección recta antes de ingresar al foramen transverso de C6. La coexistencia de variaciones bilaterales en las arterias vertebrales es posible. Esta situación atípica, potencialmente puede generar en la persona patologías neurológicas de origen vascular, pero con sintomatología y causas diferentes. Conocer estas variaciones y realizar una búsqueda intencionada de ellas permitirá el especialista realizar un adecuado diagnóstico diferencial.

Spontaneous bilateral pneumothorax in a previously healthy COVID-19 patient: A case report

Coronavirus disease 2019 (COVID-19) is commonly linked with mild cough, fever, and shortness of breath symptoms. However, there have been reports of pneumothorax, which particularly occurred at least 1 week following symptom onset in elderly COVID-19 patients. Spontaneous pneumothorax (SP) is an uncommon but possibly fatal complication of COVID-19 pneumonia and is rarely reported in non-intubated patients. We report a case of a healthy, non-smoker 35-year-old young woman who presented with a 7-day cough, fever, and sudden shortness of breath. She was diagnosed with severe COVID-19 pneumonia, experienced a right SP, and developed a second pneumothorax on the contralateral side. She improved gradually following chest tube insertion in the right lung and conservative management for the left pneumothorax.

Split cricoideo anterior posterior: una novedosa técnica para evitar la traqueotomía en parálisis cordal bilateral en pacientes pediátricos / Posterior anterior cricoid split: a cutting-edge technique to avoid tracheostomy in bilateral cordal paralysis in pediatric patients

Introducción: La parálisis cordal bilateral en aducción es la segunda causa de estridor congénito y genera una grave obstrucción de la vía aérea, debutando con estridor. La traqueotomía ha sido durante mucho tiempo el gold estándar para el tratamiento de esta afección, no exenta de complicaciones. Existen procedimientos que intentan evitar la traqueotomía, como el split cricoideo anterior posterior endoscópico (SCAPE). Objetivo: Presentar experiencia con SCAPE en pacientes pediátricos como tratamiento alternativo de parálisis cordal bilateral en aducción. Material y Método: Análisis retrospectivo de los resultados quirúrgicos obtenidos en pacientes con parálisis cordal bilateral en aducción tratados con SCAPE entre enero de 2016 y diciembre de 2019 en el Hospital Guillermo Grant Benavente de Concepción, Chile. Resultados: Siete pacientes se sometieron a SCAPE. Todos los pacientes presentaban insuficiencia respiratoria severa, cinco requirieron asistencia ventilatoria mecánica. Seis pacientes tenían el diagnóstico de parálisis cordal bilateral (PCB) congénita y uno PCB secundaria a tumor de tronco cerebral. Cuatro pacientes presentaron comorbilidad de la vía aérea: dos pacientes presentaron estenosis subglótica grado I y dos pacientes presentaron laringomalacia que requirió manejo quirúrgico. Los días promedio de intubación fueron once días. Ningún paciente requirió soporte ventilatorio postoperatorio, sólo un paciente recibió oxigenoterapia nocturna debido a hipoventilación secundaria a lesión de tronco. Ningún paciente ha presentado descompensación respiratoria grave. Un 40% ha recuperado movilidad cordal bilateral. Conclusión: Split cricoideo anteroposterior endoscópico es una alternativa eficaz para tratar el PCB en pacientes pediátricos. Nuestro estudio evidencia que es una alternativa a la traqueotomía, con excelentes resultados y menor morbimortalidad.

Introduction: Bilateral vocal fold paralysis in adduction is the second cause of congenital stridor and generates a serious obstruction of the airway. Tracheostomy has long been the gold standard for the treatment of this condition, but it has inherent complications. There are procedures that try to avoid tracheotomy, such as the endoscopic anterior posterior cricoid split (EAPCS). Aim: Present our experience with EAPCS in pediatric patients as a treatment for bilateral vocal fold paralysis in adduction. Material and Method: Retrospective analysis of the surgical results obtained in patients with bilateral vocal cord paralysis in adduction treated with EAPCS between January 2016 and December 2019 at Guillermo Grant Benavente Hospital in Concepción, Chile. Results: Seven patients underwent EAPCS. All patients had severe respiratory failure, five required mechanical ventilation assistance. Six patients were diagnosed with congenital bilateral cord palsy (BCP) and one BCP secondary to a brainstem tumor. Four patients had airway comorbidity: two patients had grade I subglottic stenosis and two patients had laryngomalacia that required surgical management. The average days of intubation were eleven days. No patient required post op invasive/non-invasive ventilation, only one patient received nocturnal oxygen therapy due to hypoventilation secondary to trunk injury. None of the patients has presented severe respiratory decompensation. Forty percent have recovered bilateral chordal mobility. Conclusion: SCAPE is a cutting-edge and effective alternative to treat PCB in pediatric patients. Our study shows that it is an alternative to tracheotomy, with excellent results and lower morbidity and mortality.

Músculo Esternal Bilateral, Descripción de un Caso e Implicancias Clínicas / Bilateral Sternal Muscle, Description of a Case and Clinical Implications

El músculo esternal corresponde a una variante muscular supernumeraria de la musculatura torácica, cuya descripción más antigua se remonta al año 1604. A lo largo de la historia ha sido denominado músculo "epiesternal", "preesternal", "recto torácico" o "recto esternal". Se ubica entre la fascia superficial y el músculo pectoral mayor, tiene una prevalencia de entre 3 % y 8 % en la población general, se presenta de forma unilateral o bilateral exhibiendo una alta variabilidad interracial y puede ser motivo de dilemas diagnósticos durante cirugías y exámenes de imagen. Disección en un cadáver adulto de sexo masculino. Se encontraron dos músculos esternales conectados superiormente por un tendón central. El músculo esternal derecho se extendía desde el manubrio esternal hasta el séptimo cartílago costal derecho. El músculo esternal izquierdo se extendía desde el manubrio esternal hasta el sexto cartílago costal izquierdo. Su inervación estaba dada por ramos cutáneos anteriores de los nervios intercostales y su vascularización por ramas perforantes provenientes de los vasos torácicos internos. El músculo esternal presenta una alta variabilidad morfológica y su prevalencia se ve influenciada por factores raciales. Conocer esta variación muscular enriquece la capacidad diagnóstica y quirúrgica reduciendo la posibilidad de iatrogenia.

SUMMARY: The sternal muscle corresponds to a supernumerary muscle variant of the thoracic musculature, whose oldest description dates to 1604. Throughout history it has been called the "episternal", "presternal", "rectus thoracis" or "rectus sternalis" muscle. It is located between the superficial fascia and the pectoralis major muscle, has a prevalence of between 3 % and 8 % in the general population, presents unilaterally or bilaterally, exhibits a high interracial variability and can be the cause of diagnostic dilemmas during surgery and imaging examinations. Dissection in an adult male cadaver. Two sternal muscles were found connected superiorly by a central tendon. The right sternal muscle extended from the sternal manubrium to the right seventh costal cartilage. The left sternal muscle extended from the sternal manubrium to the left sixth costal cartilage. The innervation was given by anterior cutaneous branches of the intercostal nerves and the vascularization by perforating branches coming from the internal thoracic vessels. The sternal muscle presents a high morphological variability and the prevalence is influenced by racial factors. Knowing this muscle variation enriches the diagnostic and surgical capacity, reducing the possibility of iatrogenesis.

Exploring the Bilateral Comparisons of Articular Surfaces of Talus: An Observational Study at Tertiary Health Care Center in Pune City

Background: The existing conclusive data show variations in the subtalar joint regarding its morphological features and articulation of bones. Inadequate studies exist on the morphometry of articular surfaces of the talus which may help in surgical interventions and development of implants and prostheses in diverse populations. Purpose: The current study was undertaken to conduct a bilateral comparison of parameters of articulating surfaces of talus. Material and Methods: An observational study design was carried out at one of the private medical colleges in the Pune district of Maharashtra. A total of 100 (fifty-one from right side and forty-nine left-sided tali) dry human talar bones were collected and various dimensions of articular surfaces of bones were measured by Digital Vernier Caliper and Ruler. The data analysis was performed and results were tabulated and presented graphically. Results: There was a statistically significant difference (p<0.05) in bilateral measurements of lateral articular surface height (LASH) of talar bones. The difference was not significant (p>0.05) for all other parameters. Conclusions: The study inferences can be applied as a guide and baseline information for surgical measures, inflammatory disease management, and forensic anthropologists.

A novel two-surgeon technique of simultaneous bilateral cataract surgery with complete delinking

Though technological advancements have transcended beyond expectation, phacoemulsification remains a challenge in uncooperative patients, where the procedure may be contemplated under general anesthesia, with simultaneous bilateral cataract surgery (SBCS) being the surgery of choice. In this manuscript, we have reported a novel two-surgeon technique of SBCS on a 50-year-old mentally subnormal patient. Under general anesthesia, two surgeons performed phacoemulsification simultaneously, using two separate microscopes, irrigation lines, phaco machines, instruments, and assistants. Intraocular lens (IOL) implantation was performed in both eyes (OU). The patient had a visual recovery from 5/60, N36 in OU preoperatively to 6/12, N10 in OU on post-operative day 3 and 1 month, with no complications. This technique can potentially reduce the risk of endophthalmitis, repeated and prolonged anesthesia, and the number of hospital visits. To the best of our knowledge, this two-surgeon technique of SBCS has never been reported in the literature.

Disposición hacia la colaboración médica internacional en estudiantes de Estomatología de ocho universidades cubanas / Willingness towards international medical collaboration in dental students from eight Cuban universities

Introducción: Cuba se ha caracterizado por enviar a diversos países delegaciones de salud, llamadas "misiones médicas". Sin embargo, el interés de los futuros profesionales de formar parte de esas delegaciones no se ha investigado. Objetivos: Caracterizar la disposición hacia la colaboración médica internacional e identificar los factores asociados en estudiantes cubanos de Estomatología. Métodos: Se realizó una investigación transversal, analítica de datos secundarios, en estudiantes de todos los años del curso académico 2018-2019, pertenecientes a ocho universidades.

Color vision and contrast sensitivity likewise showed significant improvement. Conclusions: Simultaneous bilateral lens surgery in hyperopic patients, contributes significantly to the improvement of vision in quantity and quality, thus allowing recovery of quality of life(AU)

Manejo quirúrgico de bad split bilateral en cirugía ortognática / Surgical management of bilateral bad split during orthognathic surgery

El bad split es un término clínico que refiere a una fractura no planificada que ocurre al momento de realizar una osteotomía sagital de rama mandibular (OSRM). Afecta aproximadamente al 2,3% de los pacientes y se han descrito factores de riesgo tales como la presencia de terceros molares mandibulares, edad avanzada al momento de la cirugía, técnica de osteotomía inadecuada, entre otros. Se recomienda efectuar manio-bras preventivas para evitar la aparición de patrones de fractura no deseados al realizar la OSRM. Sin embargo, al momento de pesquisar un bad split, éste debe ser tratado por un equipo capacitado y de manera oportuna para evitar retardo en la consolidación, infecciones y secuestros óseos que puedan comprometer los resultados de la cirugía. En este artículo se presenta el manejo de un caso clínico de bad split bilateral intraoperatorio por el Servicio de Cirugía Maxilofacial del Hospital San José, enfatizando su tratamiento quirúrgico.

Bad Split is a clinical term referring to an unplanned fracture that occurs during the bilateral sagittal split osteotomy (BSSO). It affects approximately 2,3% of the patients undergoing orthognathic surgery and several risk factors have been described such as the presence of mandibular third molars, advanced age at the moment of orthognathic surgery, inadequate osteotomy technique, etc. Preventive maneuvers are recommended in order to avoid the appearance of undesired fracture patterns during BSSO. However, if a bad split is detected it must be managed and treated by a qualified team to avoid further complications such as delayed bone consolidation, bone infection and necrosis. In this article we present the management of a case of bilateral bad split by the Maxillofacial Surgery Service of Hospital San José, emphasizing on its surgical treatment.

Introducción: El síndrome de Vogt-Koyanagi-Harada pertenece a los síndromes uveomeníngeos y es una de las principales enfermedades que amenazan la visión. Se caracteriza por una uveítis bilateral que se asocia frecuentemente con manifestaciones neurológicas, auditivas y tegumentarias. Recientemente un fenotipo particular de engrosamiento macular se ha descrito como desprendimiento bacilar asociado a esta enfermedad. Objetivo: Describir el desprendimiento bacilar de la retina mediante la tomografía de coherencia óptica de dominio espectral en un caso de Vogt Koyanagi Harada en fase uveítica. Presentación de caso: Paciente femenina de 46 años de edad atendida en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" con disminución de agudeza visual en ambos ojos y panuveitis bilateral. Fue diagnosticada con síndrome de Vogt-Koyanagi-Harada en su fase uveítica aguda con presencia de manifestaciones neurológicas y desprendimiento de la capa bacilar de la retina identificado mediante la tomografía de coherencia óptica de dominio espectral. Conclusiones: El síndrome de Vogt-Koyanagi-Harada aguda y el desprendimiento bacilar de la capa de la retina pueden diferenciarse de otros signos mediante la tomografía de coherencia óptica de dominio espectral. Su desaparición pudiera tener una relación con la mejoría de la agudeza visual(AU)

Introduction: Vogt-Koyanagi-Harada syndrome belongs to the uveomeningeal syndromes and is one of the major vision-threatening diseases. It is characterized by bilateral uveitis, which is frequently associated with neurological, auditory and integumentary manifestations. Recently a particular phenotype of macular thickening has been described as bacillary detachment associated with this disease. Objective: To describe bacillary retinal detachment using spectral domain optical coherence tomography in a case of Vogt Koyanagi Harada in uveitic phase. Case presentation: 46-year-old female patient attended at the Cuban Institute of Ophthalmology "Ramón Pando Ferrer" with decreased visual acuity in both eyes and bilateral panuveitis. She was diagnosed with Vogt-Koyanagi-Harada syndrome in its acute uveitic phase with presence of neurological manifestations and detachment of the bacillary layer of the retina identified by spectral domain optical coherence tomography. Conclusions: Acute Vogt-Koyanagi-Harada syndrome and bacillary retinal layer detachment can be differentiated from other signs using spectral-domain optical coherence tomography. Their disappearance could be related to the improvement of visual acuity(AU)

Bilateral acute depigmentation of the iris determined in two cases after COVID-19 infection

Bilateral acute depigmentation of the iris (BADI) is a rare disease characterized by iris atrophy. Although it can be self-limiting, it is sometimes progressive and can lead to glaucoma and severe vision loss. Two female patients were admitted to our clinic because of a change in iris color following coronavirus disease 2019 (COVID-19) infection. After the exclusion of other etiologies in the eye examination, BADI was diagnosed in both cases. Thus, it was shown that COVID-19 may also be involved in the etiology of BADI.

Diagnóstico y tratamiento quirúrgico de una paciente con una neoplasia trofoblástica gestacional / Diagnosis and surgical treatment of a patient with gestational trophoblastic neoplasia

Resumen ANTECEDENTE: La neoplasia trofoblástica gestacional forma parte del grupo de afecciones derivadas de la proliferación anómala del trofoblasto con capacidad para invasión y metástasis. CASO CLÍNICO: Paciente de 42 años, asintomática, con sospecha ecográfica de mola hidatiforme. El legrado uterino y el estudio anatomopatológico confirmaron el diagnóstico de mola hidatiforme completa. Con la cuantificación consecutiva de tres elevaciones de la β-HCG se diagnosticó: neoplasia trofoblástica gestacional. Se estadificó en estadio I, bajo riesgo y ante el deseo genésico satisfecho la paciente aceptó la histerectomía más salpingectomía bilateral. En el seguimiento posterior la paciente se encontró asintomática, con determinaciones seriadas de b-HCG negativa y ecografías vaginales sin hallazgos. CONCLUSIÓN: La histerectomía con salpingectomía bilateral puede ser el tratamiento definitivo en casos seleccionados de neoplasia trofoblástica. La evidencia disponible es escasa, por lo que es necesario seguir investigando en este campo.

Abstract BACKGROUND: Gestational trophoblastic neoplasia is one of a group of conditions resulting from abnormal trophoblast proliferation with capacity for invasion and metastasis. CLINICAL CASE: 42-year-old asymptomatic patient with ultrasound suspicion of hydatidiform mole. Uterine curettage and anatomopathological study confirmed the diagnosis of complete hydatidiform mole. With the consecutive quantification of three elevations of β-HCG a diagnosis of gestational trophoblastic neoplasia was made. It was staged as stage I, low-risk, and the patient agreed to hysterectomy plus bilateral salpingectomy. At subsequent follow-up the patient was found to be asymptomatic, with negative serial determinations of β-HCG and vaginal ultrasound scans without findings. CONCLUSION: Hysterectomy with bilateral salpingectomy may be the definitive treatment in selected cases of trophoblastic neoplasia. The available evidence is scarce and further research is needed in this field.

Embarazo ectópico tubárico bilateral simultaneo, a propósito de una caso

Los embarazos ectópicos se producen en 1 de cada 150 gestaciones, siendo una entidad patológica frecuente, sin embargo el embarazo ectópico bilateral simultaneo es un evento muy raro. El presenta caso trata de una paciente de 34 años de edad derivada de centro de salud de área rural con el diagnostico preliminar de: embarazo de 8 semanas de gestación por FUM, además de hemorragia de la primera mitad del embarazo. Posterior a realizar un ultrasonografía se concluye con imágenes sugestivas de Gestación ectópica anexial derecha, realizándose una intervención quirúrgica de la paciente, encontrándose en ambos anexos tumoraciones negruzcas, confirmándose en el servicio de patología un embarazo ectópico tubárico bilateral simultaneo. El cuadro clínico es prácticamente el mismo que en el embarazo ectópico unilateral, sin embargo el diagnóstico del embarazo tubárico bilatera resulta de gran dificultad, el tratamiento laparoscópico de la sospecha de embarazo tubárico suele ser el método más frecuente para el diagnóstico de embarazo tubárico bilateral.

Ectopic pregnancies occur in 1 in 150 pregnancies, being a frequent pathological entity, however simultaneous bilateral ectopic pregnancy is a very rare event. The case presented deals with a 34-year-old patient, referred to a health center in a rural area with the preliminary diagnosis of: pregnancy of 8 weeks of gestation due to FUM, in addition to hemorrhage in the first half of the pregnancy. After performing an ultrasonography, images suggestive of a right adnexal ectopic pregnancy were concluded, performing a surgical intervention on the patient, finding blackish tumors in both annexes, confirming a simultaneous bilateral tubal ectopic pregnancy in the pathology service. The clinical picture is practically the same as in unilateral ectopic pregnancy, however the diagnosis of bilateral tubal pregnancy is very difficult, laparoscopic treatment of suspected tubal pregnancy is usually the most frequent method for the diagnosis of bilateral tubal pregnancy.

Comparison of prophylactic ipsilateral and bilateral central lymph node dissection in papillary thyroid carcinoma: a meta-analysis

Abstract Objective: The scope of surgical resection for paratracheal (level VI) lymph nodes in patients with Papillary Thyroid Carcinoma (PTC) remains debatable. The aim of our study was to evaluate the effectiveness and safety of prophylactic ipsilateral Central Neck lymph node Dissection (CND) versus bilateral CND at the time of total thyroidectomy for Clinically Node-negative (cN0) unilateral PTC. Methods: A systematic retrieval of electronic databases, including Pubmed, Web of Science, and the China Journal Net, was conducted from January 1990 to September 2021. Outcome data of interest included transient hypoparathyroidism, permanent hypoparathyroidism, transient Recurrent Laryngeal Nerve (RLN) injury, permanent RLN injury and local recurrence. We constructed the summary Odds Ratios (ORs) and 95% Confidence Intervals (CIs) for every study with either fixed or random effect models. Results: A full total of 1792 patients from 6 studies were enrolled. Our meta-analysis showed that transient hypoparathyroidism was significantly more frequent in bilateral CND group (OR = 0.58; 95% CI 0.44-0.76). The prevalence of permanent hypoparathyroidism was significantly higher in bilateral CND group patients compared to those in ipsilateral CND group (OR = 0.26; 95% CI 0.15-0.45). On the other hand, our meta-analysis indicated that there were no significant differences in the incidence of transient RLN injury, permanent RLN injury and local recurrence. Conclusions: Compared with bilateral CND, the rate of temporary and permanent hypoparathyroidism in ipsilateral CND is lower, but the local recurrence is similar. It may be presumptuous to suggest that ipsilateral CND is an adequate treatment for cN0 unilateral PTC.

Prise en charge des lithiases submandibulaires bilatérales au service de stomatologie et chirurgie maxillo-faciale du CHU de Treichville à propos d'un cas management / Bilateral submandibular lithiasis in the department of stomatology and maxillofacial surgery at Treichville University Hospital: A Case Report

Introduction : La lithiase est la plus courante des affections salivaires chez l'adulte. Elle touche principalement la glande submandibulaire. L'atteinte isolée d'une glande est habituelle. Cependant, la lithiase simultanée des deux glandes submandibulaires est moins fréquente. L'objectif était de décrire à partir de l'observation d'un cas, les caractéristiques physiopathologiques, diagnostiques et thérapeutiques de la lithiase submandibulaire bilatérale. Observation : Une patiente de 53 ans, commerçante a consulté en Mars 2022 au Service de Stomatologie et Chirurgie Maxillo-faciale du CHU de Treichville pour une tuméfaction submandibulaire bilatérale. Cette tuméfaction évoluait depuis un an et augmentait de volume au cours des repas. Les antécédents familiaux ont mis en évidence une lithiase submandibulaire bilatérale chez une tante. L'examen clinique a retrouvé une tumeur submandibulaire droite et gauche. L'échographie submandibulaire était en faveur d'une lithiase submandibulaire bilatérale. Une submandibulectomie bilatérale a été réalisée. Aucune complication post opératoire n'a été observée et la patiente est sortie de l'hôpital après deux jours d'hospitalisation. Discussion : Les antécédents familiaux de sialolithiase suggèrent la recherche d'une origine génétique ou familiale de la lithiase bilatérale des glandes submandibulaires, s'il n'existe pas une étiologie évidente ou probable. Conclusion : La lithiase submandibulaire bilatérale est un fait clinique rare mais qu'il faut savoir rechercher même en cas de lithiase submandibulaire isolée.

Introduction: Lithiasis is the most common salivary disease in adults. It mainly affects the submandibular gland. Isolated involvement of one gland is common. However, simultaneous lithiasis of both submandibular glands is less frequent. The objective was to describe, from the observation of a case, the physio-pathological, diagnostic, and therapeutic characteristics of bilateral submandibular lithiasis. Observation: A shopkeeper of 53 years old, consulted a doctor for bilateral submandibular swelling in March 2022 at the Stomatology and Maxillofacial Surgery at Treichville University Hospital. That swelling has been developing for a year. The family history revealed bilateral submandibular lithiasis in an aunt. Clinical examination showed a right and left submandibular tumor that gained volume during meals. The submandibular ultrasound showed bilateral submandibular lithiasis. A bilateral sub-mandibulectomy was performed. No postoperative complications were observed, and the patient was discharged after a two-day hospital stay. Discussion: In the absence of an obvious or probable etiology, a family history of sialolithiasis suggests a genetic or familial origin for bilateral submandibular gland lithiasis. Conclusion: Bilateral submandibular lithiasis is a rare clinical finding but should be investigated even in cases of isolated submandibular lithiasis
