Video-assisted thoracoscopy for diaphragmatic plication: experimental study in a canine model.

BACKGROUND: Plication of a nonfunctional hemidiaphragm usually restores altered ventilatory mechanics. This study compared two techniques in performing diaphragmatic plication: video-assisted thoracoscopy (group A) and thoracotomy (group B). MATERIALS AND METHODS: Twenty dogs with induced paralysis of the right hemidiaphragm were randomly assigned to one of the two groups. Evaluations were performed before and after plication of the respiratory frequency (f) and lung area (LA) of the affected side. Operative time, time to resumption of walking, ingestion of fluids and solid food, pain intensity, and postoperative complications were measured. RESULTS: Group A had less pain after the surgery (P < 0.0001), earlier fluid ingestion (P < 0.05), and earlier resumption of walking (P < 0.019). Four weeks after the procedure, LA was similar in both groups, while a significant decrease in f was recorded in group A (P < 0.02). The remaining evaluated variables showed no differences. CONCLUSION: Both approaches were effective. Pain recorded in the postoperative period was less and recovery was faster in group A. Complications and surgical times were similar. The video-assisted thoracoscopy is a safe and efficient option for performing diaphragmatic plication in dogs.

Exogenous lipoid pneumonia superinfected with acid-fast bacilli in infants: a report of nine cases.

Super-infection of an exogenous lipoid pneumonia by nontuberculous mycobacteria has been described in the literature. It produces a distinctive histologic picture with suppurative, noncaseating granulomas surrounding lipid vacuoles containing acid-fast bacilli. Mainly isolated cases have been found, but seldom in children. We describe a series of 9 children with similar histological findings. All our patients were under 1 year of age, malnourished, and with chronic respiratory symptoms. The diagnosis, based on the characteristic histology with acid-fast rods, was established at autopsy in 4 cases, on lobectomy specimens in 4 and by open lung biopsy in 1. Mycobacterium fortuitum-chelonei was cultured in 1 case. Gastro-esophageal reflux was documented in all 4 cases in which it was explored. Aspiration of lipid gastric contents or of oil given as medication can result in exogenous lipoid pneumonia, which in turn becomes super-infected with mycobacteria. Recognition of the distinctive histology permits the diagnosis of this complication.

[Clinicopathologic cases].

The clinicopathologic conference (CPC) was introduced by Dr. Richard C. Cabot at the Massachusetts General Hospital in the U.S. early in the past century. In a short time, it became one of the most popular medical teaching tools in the world. Despite certain differences between beside diagnosis and CPC diagnosis, the latter is a valuable teaching exercise. During the past few decades, interest in CPCs has declined due to several issues: excessive concern with anatomic diagnosis at the expense of molecular pathogenesis and pathophysiology; emphasis on uncommon diseases; the pathologist being considered an adversary who enjoys demonstrating clinical discussion errors; autopsies failing to reveal abnormalities in physiopathologic disorders and it is not rare to fail to reveal cause of death, and the fact that very few cases are true diagnostic problems, due to advances in diagnostic techniques. In addition, with the decline of interest in autopsies during the past years, in several CPCs, many final diagnosis is performed by biopsy, laboratory tests, or imaging studies. The ideal CPC case to conserve the educational role of this exercise is an autopsy case with adequated clinical, laboratory and/or imaging studies.
