RESUMEN

Isolated fallopian tube torsion (IFTT) is a rare pathology that causes acute abdomen in women, it is even less common in pediatric patients. We present a case of an 11-year-old girl who presented with abdominal pain 24 hours of evolution, the diagnosis could not be specified with cabinet methods, so the definitive diagnosis was made using a diagnostic laparoscopy. A necrotic hemorrhagic tubal cyst was found. A left salpingectomy had to be performed due to necrosis. Early diagnosis can have a positive impact on the fertility of these patients.

RESUMEN

BACKGROUND: Hypocalcemia is a common complication of total thyroidectomy; transient hypocalcemia has been reported in up to 68% of the patients. MATERIALS AND METHODS: Chart review of all patients undergoing total thyroidectomy from 2016 to 2020. Clinical, biochemical, and pathological information was registered. We sought correlations between the different variables and the occurrence of post-operative hypocalcemia. This is a retrospective study carried out at a tertiary care teaching hospital. OBJECTIVES: The aim of the study was to ascertain the incidence of hypocalcemia after thyroidectomy and to establish potential clinical and pathological risk factors for its development. RESULTS: Three hundred and thirty-seven patients were included in this study (78% female), with a median age of 47 years. The majority (75%) harbored thyroid neoplasms. Post-operative hypocalcemia developed in 43 patients (12.7%). On bivariate analysis, the most significant risk factor was an intraoperative injury of the parathyroid glands (OR = 2.49, 95% CI = 1.11-5.59), followed by a surgical time > 2.5 h (OR = 2.0, 95% CI = 1.03-4.19), concomitant lymph node dissection (OR = 2.45, 95% CI = 1.2-4.9), and placement of drains (OR = 2.40, 95% CI = 1.19-4.87). Only parathyroid injury remained statistically significant on multivariable analysis. CONCLUSIONS: The most significant risk factor for the development of post-operative hypocalcemia after thyroidectomy is injury of the parathyroid glands, which is usually noticed by the surgeon.

INTRODUCCIÓN: La hipocalcemia es una complicación común después de una tiroidectomía; la hipocalcemia transitoria ha sido reportada hasta en el 68% de los pacientes posoperados. MATERIALS Y MÉTODOS: Revisión de expedientes de pacientes a los cuales se les realizo una tiroidectomía total entre el 2016 y 2020. La información clínica, bioquímica y patológica fue recopilada. Se busco una correlación entre las variables y el desarrollo de hipocalcemia. Es un estudio retrospectivo en un hospital escuela de atención terciaria. OBJETIVOS: Determinar la incidencia de hipocalcemia pos-tiroidectomía y establecer posibles factores de riesgo clínicos y patológicos para desarrollarlo. RESULTADOS: Se incluyeron 337 pacientes en este estudio (78% mujeres), con edad media de 47 años. La mayoría (75%) presentaron neoplasias tiroideas. Cuarenta y tres pacientes desarrollaron hipocalcemia (12.7%). En el análisis bivariado el factor de riesgo mas importante fue la lesión de paratiroides (RM = 2.49, IC95% = 1.11-5.59), seguido por un tiempo quirúrgico > 2.5 horas (RM = 2.0, IC 95% = 1.03­4.19), disección linfática (RM = 2.45, IC95% = 1.2-4.9) y la colocación de drenajes (RM = 2.40, IC95% = 1.19-4.87). Únicamente la lesión de paratiroides mantuvo significancia en el análisis multivariado. CONCLUSIONES: La lesión de paratiroides es el factor de riesgo mas grande para desarrollar hipocalcemia y generalmente es identificado por el cirujano.

RESUMEN

Pericarditis is usually a complication of viral or bacterial infection. In addition, it can be associated to systemic diseases such as autoimmune disorders, rheumatic fever, cancer, tuberculosis and AIDS. It can also be related to familial Mediterranean fever, an autosomic recessive inflammatory disease, characterized by fever, abdominal pain, and pleuritis mainly seen in persons from the Mediterranean area. In this study, we described the evolution and treatment response to colchicine in three patients with pericarditis associated to familial Mediterranean fever. Two of the patients had a pericardiectomy showing in their biopsy nonspecified inflammatory changes. Later their diagnosis were confirmed by genetic markers, echocardiogram and EKG. They were treated with antiviral and antibiotics without any improvement; subsequently they had good results with colchicine.
