ABSTRACT
La perforación gástrica neonatal es una patología rara pero potencialmente mortal; su recurrencia es aún más rara, son escasos los reportes en la literatura internacional. Se presenta el caso de una recién nacida prematura (32 semanas) y bajo peso al nacer (1725g) que el primer día de vida presentó una perforación gástrica corregida quirúrgicamente y al cuarto día postoperatorio es reintervenida con presunción diagnóstica de dehiscencia de rafía gástrica, hallándose una nueva perforación gástrica, la cual fue reparada quirúrgicamente. En ambas ocasiones la intervención quirúrgica fue temprana. La evolución posterior y desenlace fueron favorables.
Neonatal gastric perforation is a rare but potentially fatal pathology; its recurrence is even more infrequent, and there are few reports in the international literature. We present the case of a premature newborn (32 weeks) and low birth weight (1725g) who, on the first day of life, presented a surgically corrected gastric perforation and on the fourth postoperative day was re-operated with a presumed diagnosis of gastric raffia dehiscence, finding a new gastric perforation, which was surgically repaired. On both occasions, the surgical intervention was early. The subsequent evolution and outcome were favorable.
ABSTRACT
Resumen El tumor miofibroblástico inflamatorio (TMI) es una patología muy poco frecuente. Los TMI localizados en laringe pueden ocasionar disfonía o sensación de cuerpo extraño. El diagnóstico se realiza a través de pruebas de imagen y visualización directa con obtención de muestras para estudio histopatológico. Presentamos el caso de una mujer de 43 años, con antecedentes personales de carcinoma indiferenciado de nasofaringe, tratado con radioterapia y quimioterapia, que acude a revisiones periódicas en consulta de otorrinolaringología. Se objetiva por nasofibroscopia una lesión rugosa en cuerda vocal izquierda. Se realiza biopsia con fibroscopio de canal, compatible con tumoración fusocelular atípica, con áreas celulares y mixoides, sospechosa de malignidad, con necesidad de completar estudio inmunohistoquímico. En comité de tumores de cabeza y cuello se decide cirugía programada (laringectomía supracricoidea con cricohioidoepiglotopexia) y posterior tratamiento adyuvante con quimioterapia y/o radioterapia, según resultados del estudio histopatológico. Como conclusión, el TMI es una patología que se encuentra predominantemente en el pulmón, siendo rara la afectación laríngea. Su pronóstico es favorable y el diagnóstico histopatológico es de vital importancia. El diagnóstico correcto va seguido de una escisión local amplia para prevenir la recurrencia, sin embargo, el tratamiento debe adaptarse a la ubicación del tumor y al estado del paciente.
Abstract Inflammatory myofibroblastic tumor (IMT) is a very rare pathology. IMTs located in the larynx can cause dysphonia or foreign body sensation. The diagnosis is made through imaging tests and direct visualization and confirmation with samples for histopathological study. We present the case of a 43-year-old woman with a personal history of undifferentiated carcinoma of the nasopharynx treated with radiotherapy and chemotherapy, who attended periodic check-ups in an otolaryngology clinic. A rough granulomatous lesion was observed by nasofibrolaryngoscopy in the left vocal cord. A canal fibroscope biopsy is performed, compatible with an atypical spindle cell tumor, with cellular and myxoid areas, suspicious of malignancy, requiring an immunohistochemical study to be completed. The head and neck tumor committee decides on scheduled surgery (supracricoid laryngectomy with cricohyoidoepiglottopexy) and subsequent adjuvant treatment with chemotherapy and/or radiotherapy, according to the results of the histopathological study. As a conclusion finally, the IMT is a pathology found predominantly in the lung, laryngeal involvement being rare. Its prognosis is favorable and the histopathological diagnosis is of vital importance to be able to be differentiated from other malignant neoplasms. The correct diagnosis is followed by a wide local excision to prevent recurrence, however, treatment must be tailored to the location of the tumor and the condition of the patient.

Background: Pulmonary diseases are common among HIV infected patients. The prevalence of the different diseases varies greatly. Aim: To identify the different pulmonary diseases that affect a Chilean population of HIV infected patients and to identify factors associated with in hospital mortality. Material and methods: Retrospective review of the clinical records of all HIV infected patients with lung diseases discharged from our institution during a period of 3.5 years. Collection of demographic and biomedical data. Results: One hundred seventy one patients (aged 35.7 years, 86% men) had 236 episodes of lung diseases. Only 13.5% of the patients were receiving antiretroviral therapy and 18% were on pneumocystis prophylaxis. Infectious diseases accounted for 87% of the discharges, neoplasm for 5.1%. Pneumocystis jirovecii infection was responsible for 37.7% of the episodes, community acquired pneumonia was seen in 24.1% and mycobacterial diseases in 14.4%. Two or more conditions were present in 13.6%. Death during hospital stay occurred in 19.5%. Multivariate analysis identified pneumothorax as the only significant independent predictor of in-hospital mortality in patients with pneumocystis pneumonia, while nosocomial pneumonia was the only predictor of death among patients with non-pneumocystis pulmonary diseases. Conclusions: Infectious diseases were the main cause of hospitalization among Chilean HIV infected patients. Mortality among these patients remains high. Appropriate antiretroviral therapy and prophylaxis may alter pulmonary disease prevalence in the future. Every effort should be made to avoid the development of pneumothorax and nosocomial pneumonia.

Solid and papillary epithelial tumor of the pancreas occurs mainly in young women and its main characteristic is the appearance of an abdominal mass which progressively increases in size. The radiologic, surgical and pathological correlation shows that it is a tumor of low grade malignancy with a favorable prognosis, after therapy and according to the location of the tumor. The authors report the clinical history of the first two confirmed cases of this entity in Panama, which occurred in 1985 and 1992, respectively, in women less than 25 years of age
