[Abdominoscrotal hydrocele: a problem in differential diagnosis]. / Hidrocele abdominoescrotal: problema de diagnóstico diferencial.

Abdominoscrotal hydrocele represents a very rare eventuality in childhood; nowadays, only 14 cases have been reported in the world literature and the present case is the first one in our country. In this patient the coexistence of a small scrotal hydrocele and cystic mass at the right side is described. The results of the studies and exams are showed, and the type of the surgical excision and its findings are commented. Three theories are the most cited in order to explain its genesis, but the one supported by Laplace's law is very scientific and convincing. At the light of the different cases reported in the literature, a suggested classification is discussed and different entities are analysed in order to get a differential diagnosis; finally, the idoneous surgical therapy is reviewed.

[Comparative study in the management of pleural effusion]. / Estudio comparativo en el manejo del derrame pleural.

At the Pediatric Surgery Department of the Hospital de Especialidades of the I.M.S.S. at Puebla, 40 patients with thoracic empyema were studied appreciating some clinical, radiologic and bacteriological variables; they were divided into two groups: 16 cases who had a thoracotomy and decortication and 24 with a conservative management. The hemithorax of the right side was the most affected, and the complications more often seen were the pachypleuritis, pneumatoceles and the persistence of a bronchopleural fistula. The operated group recovered without sequelae, having been hospitalized for 38.9 days average. The second group was discharged around the second week of treatment, without fever or respiratory symptoms even with an "abnormal" X-ray film. Every patient was checked clinically and radiologically every month, noticing, that the pachypleuritis and cysts were disappearing in a progressive way, lasting 6 to 8 months for complete recovery in all of the patients.

[Syndrome of the 1st and 2nd branchial arches. Report of 3 cases]. / Síndrome del primero y segundo arcos branquiales. Communicación de tres casos

Three newborn babies were studied in our hospital with the following associated unilateral deformities: macrostomia, hemignathia and anomalies of the external ear. The main symptom was the inability for suction causing some weight loss. These cases could be logically named "syndrome of the first and second branchial arches" because of their common origin. We discuss the pathogenesis and the differences with other diseases including those of hereditary origin. The initial management is discussed.
