Isolated hepatic tuberculosis in a transplanted liver.

BACKGROUND: The incidence of tuberculosis (TB) has been increasing, especially in immunocompromised patients. It was reported that the overall incidence of TB in solid-organ transplant recipients is 0.8%. Hepatic graft TB was reported once before in a child, who underwent living-related hepatic graft transplantation. CASE REPORT: A 43-year-old man underwent orthotropic liver transplantation (OLT) in October 1999. His pre-transplant work-up was negative for TB (history and PPD skin test). He developed an episode of acute rejection which responded to steroids. He was discharged home on December 1999 with normal liver function tests (LFT). His LFT remained normal during January 2000, but his serum transaminases were found elevated on February 2000 (aspartate aminotransferase [AST] 206, alanine aminotransferase [ALT] 266). A liver biopsy then showed no evidence of TB or cytomegalovirus disease. The patient continued to have stable elevation of his serum AST and ALT until late March 2000 when a repeat liver biopsy showed caseating granuloma. The patient was started on anti-TB medications, with which he was compliant. By mid-May 2000 he was doing well, with significant reduction in his transaminase levels (AST 72, ALT 79). A retrospective inquiry about the donor revealed that he was a healthy young man from India, who died in a road traffic accident. CONCLUSION: To our knowledge our patient appears to be the first case reported of isolated hepatic TB in the OLT patient population. It is likely that the allograft was infected prior to transplantation and the disease was reactivated nearly 3 months after the procedure.

Consanguineous marriage in an urban area of Saudi Arabia: rates and adverse health effects on the offspring.

The objective of this cross-sectional study was to determine the pattern and time trend of consanguineous marriage and its adverse health effects on the offspring in Dammam city, Eastern Province, in the Kingdom of Saudi Arabia. This city is known to attract Saudis from different parts of the country because it is in the heart of this industrial region. Five primary health care centers were randomly selected from different sectors of the city in addition to the city's only Maternity and Children's Hospital. For inclusion in the study a wife must have at least one pregnancy that terminated in either full term liveborn baby, still birth, or abortion. A total of 1307 ever-married Saudis completed a pre-structured questionnaire during an interview. The rate of consanguineous marriage was 52.0% with an average inbreeding coefficient of 0.0312. First-cousin marriages were the commonest (39.3%) of all matings. The consanguineous groups had a significantly higher number of pregnancies. The mean birth weight of the offspring of consanguineous couples was not statistically significant being less than that of the non-consanguineous. However, within the consanguineous groups the more closely related couples had smaller babies on average. No significant differences were noted for the rates of inherited diseases and reproductive wastage. The rate of consanguineous marriage in this city was high and so was the inbreeding coefficient. These figures place this nation among the countries with a high rate of consanguineous marriages. A nationwide study to determine accurately the relationship between consanguinity and inherited diseases has much to commend it.

An overview of breast cancer.

Breast cancer is a major health problem in many parts of the world. Its impact in Saudi Arabia will be more obvious when the national data is released from the National Cancer Registry (NCR) in the near future. It is the most common cancer referred to the King Faisal Specialist Hospital and Research Centre (KFSH&RC). This is a retrospective review of all female breast cancer cases treated at KFSH&RC over a 15-year period. Patients were divided into two groups at the time of their referral to KFSH&RC: metastatic and nonmetastatic. We describe the demographic data, cancer-related information and the treatments offered to all patients. Comparisons were made between Saudi and non-Saudi, and the Saudis were examined in relation to their region of referral and observed to see if any changes occurred during the study period. As well, we tried to compare our results with experience elsewhere. A total of 1584 female breast cancer patients were treated at KFSH&RC between 1975 and 1991. Early breast cancer (Stages I, II) represented 36%, while 64% presented with advanced or metastatic disease (Stages III, IV). The majority of patients were premenopausal (64%). For patients with Stages I-III (1005), mastectomy was performed in 85% and lymph node dissection in 93%. Only 30% had no pathologic lymph node involvement and in 49% of the patients, lymph node dissection was adequate (>/= 10 nodes removed). Estrogen and progesterone receptors were known in 30% of the patients. Sixty-two percent and 72% of patients referred from the central region and the northern region had Stages II and III, respectively. For the non-Saudis, we observed more premenopausal patients (76%) and fewer Stage III. At 15 years, the relapse-free survival in Stages I, II and III was 33%, 36% and 18%, and the overall survival was 80%, 64% and 45%, respectively. Breast cancer in this population affects younger patients (premenopausal) and a higher proportion present with metastatic or locally advanced disease. Management strategies should incorporate conservative surgery when appropriate, and adequate lymph node dissection. This should be coupled with increasing public awareness and education and institution of screening programs. Overall survival is clearly linked to the stage of the disease.

Bilateral chylothorax following neck dissection.

BACKGROUND: Bilateral chylothorax, as a complication of neck dissection, is extremely rare, and was first described in 1907. Ten cases are reported in the literature. METHODS: This presentation illustrates an additional case of bilateral chylothorax occurring after neck dissection. Anatomic and physiologic considerations are presented and possible mechanisms of pathogenesis are discussed. RESULTS: Chylothorax has two major complications: respiratory and metabolic. The modern concepts of treatment are summarized. CONCLUSIONS: After neck dissection, the clinician should suspect chylothorax if the patient had respiratory embarrassment and an abnormal chest x-ray postoperatively.
