Tuberculous pericarditis: three cases and brief review.

Tuberculous pericarditis is a form of extrapulmonary tuberculosis that is considered unusual in western coun-tries. Diagnosis is often challenging, while proper treatment has a major impact on prognosis. We present three interesting cases, with complicated or unusual manifestations of tuberculous pericarditis: a patient with cardiac tamponade as the initial manifestation of tuberculosis; a patient progressing to constriction despite adequate treatment; and a patient receiving anti-TNFalpha, who developed pericarditis in the context of immune reconstitution inflammatory syndrome. We briefly review the clinical features of tuberculous pericarditis, whilst our main focus is on the available diagnostic techniques and treatment aspects. In conclusion, tuberculous pericarditis remains an active thread in the western world. A high index of suspicion combined with the use of all available diagnostic techniques are important to increase diagnostic yield. Prompt and effective treatment is essential to reduce morbidity and mortality.

Bronchobiliary fistulae due to echinococcosis.

OBJECTIVE: A bronchobiliary fistula (BBF) is a rare complication of echinococcosis due to rupture of hydatid cysts located at the upper surface of the liver to the bronchial tree. We present our experience in treating this uncommon and dangerous entity. MATERIAL: During the last 20 years, 21 patients, ten men and 11 women ranging in age from 26 to 83 years with a BBF were treated in our department. They presented dyspnea, biloptysis, cough or fever. Diagnostic imaging studies have been very helpful in identifying the communication and in delineating its location. The disease was limited to the liver in 11 cases, whereas in the rest ten cases, both liver and lung were involved. RESULTS: Right thoracotomy was the approach of choice. Our strategy consisted of adequate evacuation of the intrahepatic cysts, obliteration of the cyst space, freeing the adherent lung, dissection and closure of the BBF. Two deaths occurred due to anaphylactic shock and cardiac insufficiency. Follow up at 7-12 years did not reveal any recurrence. CONCLUSION: Although the incidence of echinococcosis has been decreased, the BBF still remains a serious complication with a high morbidity and mortality. Early diagnosis and management of septic associated complications are essential.

Management of esophageal foreign bodies: a retrospective review of 400 cases.

OBJECTIVE: A retrospective study was conducted in 400 patients with esophageal foreign bodies (EFB) to assess characteristics of EFB and methods of treatment. METHODS: From 1962 through 1998, 400 patients with EFB were treated in our department on an emergency basis. There were 202 men (50%) and 198 women (49.6%) ranging in age from 1.5 to 95 years. The main symptoms patients complained of were difficulty in swallowing and pain. Detailed anamnesis, oropharynx and hypopharynx examination and finally radiological examination were the diagnostic tools. The location of the FB was in the cervical esophagus in 57% of cases, in the thoracic one in 26% and at the cardioesophageal junction in 17%. The most common objects found were bones, morsels, coins and needles. RESULTS: The treatment consisted of rigid esophagoscopy under general anesthesia in 343 (85.7%) of our cases. In 57 cases (14.3%) other means such as flexible esophagoscopy, Fogarty or Foley catheters and bougienage turned to be very useful. Only 12 patients (3%) were led to surgery because either extraction was impossible or perforation was present. No major complications occurred in the surgical group, whereas in the group of rigid esophagoscopy, there was one iatrogenous esophageal perforation that presented with empyema thoracis successfully treated. Finally, there was a case of an aortoesophageal fistula with mortal outcome perioperatively. CONCLUSIONS: (1) Esophagoscopy is a reliable method in the treatment of EFB impaction. (2) Alternative methods such as bougienage, etc., can be used only in selected cases with smooth foreign bodies. (3) Surgical treatment is unavoidable in cases of irretrievable EFB or esophageal perforation.
