Granulomatous hepatitis following open heart surgery with cardiopulmonary bypass.

BACKGROUND: Cardiopulmonary bypass (CPB) initiates an inflammatory cascade, predisposing the patient to a number of infections. The stress of surgery and anaesthesia further expose the patient to a variety of non-infectious complications. We report a group of patients who developed granulomatous disease after open heart surgery. METHODS: We retrospectively analysed a subset of patients who developed a syndrome of fever, jaundice and hepatomegaly after open heart surgery. We recruited age- and sex-matched controls who underwent open heart surgery during the same period (July 2002-July 2004). Details of demographic profiles, diagnostic evaluation and drug treatment were noted and compared between the two groups using the SPSS software. RESULTS: Five patients were identified to have the specific syndrome of high grade intermittent fever with jaundice and hepatomegaly with investigations revealing an intrahepatic cholestasis. A detailed evaluation revealed granulomas in tissue specimens of the bone marrow and/or liver in these patients. An extensive evaluation for an alternative aetiological agent was non-contributory. CONCLUSION: We found granulomatous hepatitis in 5 patients following open heart surgery and they were given conventional antituberculous therapy to which they responded. It is possible that in these patients, tuberculosis was re-activated from a dormant focus due to a period of transient immunodeficiency caused by an extracorporeal circulation.

An outbreak of post-streptococcal reactive arthritis.

We describe an outbreak of an illness with fever, mono-, pauci- or polyarticular arthritis, and high antideoxyribonuclease B (ADNB) titres in 11 patients. Two patients had concomitant non-purulent conjunctivitis and one had endogenous endophthalmitis. There was no clinical or echocardiographic (6 patients) evidence of carditis. Blood culture grew Group A beta haemolytic streptococci in one patient. A simultaneous synovial fluid culture in this patient and similar cultures in four more patients yielded no microorganism. Most patients recovered completely, but one developed rheumatoid factor negative spondyloarthropathy. Monoarticular arthritis in several patients, the absence of carditis, and the presence of high ADNB titres without high anti-streptolysin O titres indicate that this was not acute rheumatic fever but post-streptococcal reactive arthritis (PSRA).

Epithelioid haemangioma (benign haemangioendothelioma of bone)--a case report.

A case of epithelioid Haemangioma of the femur is presented. The patient, a 29 year old woman, was treated by curettage and bone grafting, following which two "recurrent" tumours appeared. These were successfully removed by repeat curettage.

Multicentric giant cell tumour of bone--a report of two cases.

Two cases of metachronous multicentric giant cell tumour of bone are reported. One patient had tumours in the tibia and the femur, the second tumour appearing five years after the first. The other patient developed tumours in the tibia and the radius, the second tumour appearing two years and nine months after the first. The metachronous tumours, in both cases, were clinically and radiologically more aggressive than the initial tumours. Treatment with curettage and bone grafting proved to be ineffective for these tumours and en-bloc excision was required for cure.

A bypass technique for aneurysms of descending aorta.

Uniformity of opinion does not exist regarding optimal surgical strategy for descending aortic aneurysms. We present a surgical technique for bypass during aortic cross clamp while operating on such aneurysms. Five patients have undergone surgery using this technique. All of them are alive, doing well with no complications.
