Caso clínico: agenesia pericárdica, diagnóstico imagenológico de una patología infrecuente / Clinical case: pericardial agenesis, radiological diagnosis of a rare disease

Resumen: La agenesia pericárdica congénita es una condición infrecuente, que generalmente cursa de forma asintomática y es diagnosticada como hallazgo radiológico. Sin embargo, se describe la asociación con malformaciones cardiacas y herniaciones del miocardio con el subsiguiente riesgo de muerte súbita. La radiografía de tórax es un pilar fundamental para la sospecha diagnóstica. Presentamos un caso clínico de una paciente de 11 años que consulta por dolor torácico y disnea, que frente a los hallazgos típicos en radiografía de tórax se sospecha agenesia pericárdica, posteriormente confirmada con TC y RM.

Abstract: Congenital pericardial agenesis is an infrequent but usually asymptomatic condition, and is diagnosed as an incidental radiological finding. However, the association with cardiac malformations and myocardial herniation with the subsequent risk of sudden death has been reported. Chest plain films are a fundamental tool to raise the diagnostic suspicion. We present a clinical case of an 11-year-old patient who consulted for chest pain and dyspnea, in which, with the typical findings on chest radiography, pericardial agenesis was suspected and later confirmed by CT and MRI.

Síndrome de hiper IgE, una enfermedad poco frecuente en edad adulta: Reporte de un caso / Hyper-immunoglobulin E syndrome: Report of one case

The Hyperimmunoglobulin E syndrome (HIES) is a rare sporadic or autosomal dominant immune and connective tissue disorder characterized by chronic eczema, cutaneous abscesses, pneumonias, invasive infections, high levels of Immunoglobulin E, primary teeth retention and bone abnormalities. We report a 24-year-old male with a history of cutaneous abscesses and esophageal candidiasis. He was admitted due to a left gluteal cellulitis. During the fifth day of hospitalization he presented a distal necrosis of the fourth finger of the right hand. Laboratory results showed high levels of IgE and positive cryoglobulins. The patient was discharged and was admitted again five days later with a new gluteal abscess. IgE levels were even higher. Applying Grimbacher scale, the diagnosis of Hyperimmunoglobulin E syndrome was reached.

Características clínicas y metabólicas de síndrome de ovario poliquístico en la ciudad de Temuco / Clinical and metabolic characteristics of polycystic ovary syndrome in the city of Temuco

Polycystic Ovarian Syndrome (PCOS) is the most common endocrine disorder, its etiologyis multifactorial. It is associated with multiple metabolic abnormalities. Objective: To evaluate statistical association between the clinical characteristics of patients diagnosed with PCOS. Patients and Methods: Descriptive study, 121 patients between 13 and 44 years with PCOS were included, and their clinical characteristics, blood glucose, insulin, lipid profile and calculated HOMA were evaluated. Data was analyzed with Chi2, considering p < 0.05 as statistically significant. Results: Mean age 25,5 years, 12,5 years menarche. 22 percent with a history of abortion. Mean BMI 31,4. Acanthosis nigricans was presented in 58,6 percent. Average Glucose 96,5 mg/dl. Insulin resistance (IR) was found in 79.3 percent. Average HOMA 4,5. 64 percent of patients with IR presented Acanthosis nigricans (p = 0.002).It showed direct relationship between BMI and RI (p 0.000). 38,8 percent had dysglycemia. RI was found in 78,7 percent of patients with dysglycemia (p 0.8). Lipid profile was measured in 78 patients, of whom 40 percent had total cholesterol above 200 mg/dl, 49 percent hypertriglyceridemia and high LDL in 13 percent of cases. Conclusions: The data reported are similar to those reported in the international literature. Ourpopulation has obesity and dyslipidemia figures higher than those reported in national studies. The menarche occurs at a younger age while the prevalence of dyslipidemia and RI is greater than the general population, forming a higher risk group...
