Ethnic and age-related fat free mass loss in older Americans: The Third National Health and Nutrition Examination Survey (NHANES III)

Background  

Although age-related loss of fat free mass (FFM) is well known, there is paucity of data on national estimates, and on the differential influence of ethnicity on the decline in FFM with increasing age. We determined whether age-related loss in FFM and fat free mass index (FFMI) vary by gender and or ethnicity, using representative data from the Third National Health and Nutrition Examination Survey (NHANES III).     

Candidaemia in a large teaching hospital: a clinical audit

BACKGROUND: Candidaemias are associated with significant morbidity and mortality. The British Society of Medical Mycology and Infectious Diseases Society of America recently published audit standards, to address the changing epidemiology of candidaemia and to improve outcomes. AIM: To investigate the local epidemiology of candidaemia and the standard of care in a large teaching hospital. DESIGN: Retrospective audit. METHODS: Data were obtained for all candidaemia episodes over the 4-year period ending July 2004, from the medical and nursing notes, laboratory computer and patient administration system. RESULTS: We identified 92 episodes in 90 patients. The main predisposing factors were being on an intensive care unit, having a central venous catheter, and (for neonates) prematurity. Central venous catheters were removed at a mean 1.8 days following candidaemia; 79% (37/47) were removed within 48 h (the audit standard). Identification and susceptibility tests were performed for 94.7% of isolates. All were susceptible to amphotericin B; 87% were susceptible to fluconazole. Antifungal treatment was started within 24 h of a positive blood culture in 84% of episodes. Initial antifungal therapy was appropriate in 95% (61/64) of treated cases. Most patients (81%) who survived or completed their intended course of treatment before death received at least 2 weeks treatment. However, only 45% of those transferred to other hospitals had accompanying guidance on the intended further duration of therapy. Thirty-day mortality was 41%. After adjustment for age, the presence of Candida-related complications was associated with an odds ratio for mortality of 6.5 (95% CI 1.2-36.5, p = 0.03). DISCUSSION: Overall the audit standards set by the BSMM and IDSA were met, and discrepancies did not lead to a change in outcome. Improved intravenous catheter care, a more pro-active approach to searching for complications, and improvement in the inter-hospital transfer process, will assist in reducing morbidity and mortality.     

Anogenital warts in Northern Nigeria: A ten-year Review

Background:

Anogenital warts are a common cause of morbidity affecting mainly the productive age group of the economy. Paucity of data in Nigeria necessitated this study.

Materials and Methods:

The pathology records of anogenital warts diagnosed in the Department of Pathology, Ahmadu Bello University Zaria between 1^st January 2000 and 31^st December 2009 were reviewed.

Results:

A total of 68 warts were diagnosed within the study period with anogenital warts constituting 39.7%. Majority of cases (62%) were in the 20-39 years age group (range: 5–50 years) and vulva was the most common site affected.

Conclusion:

Genital warts are common in our environment, biopsy of suspicious lesions is recommended for diagnostic yield.     

Serum alpha-fetoprotein level is higher in hepatitis C than hepatitis B infected chronic liver disease patients

Background:

The frequency of raised serum alpha-fetoprotein may vary in relation to hepatitis B or C infection in chronic liver disease (CLD). The study evaluated the frequency of hepatitis B and C in patients with chronic liver disease and correlated the levels of serum alpha-fetoprotein with hepatitis B and C infection in the patients.

Materials and Methods:

Eighty-six patients with CLD were recruited for the study. Fifty subjects, with no CLD were used as control. Hepatitis B surface Antigen (HBsAg) and hepatitis C antibody were determined using enzyme-linked immunosorbent assay (ELISA) technique (Human diagnostics, Germany and HCV Murex 40 Anhet laboratories, USA) while liver function tests were evaluated using express plus chemistry auto analyzer. Alpha-fetoprotein was assayed using ELECSYS 1010 auto analyser.

Results:

There were 60 males and 26 females, with a mean age of 46 + 6.5 years, while the controls were 25 males and 25 females with a mean age of 41 ± 2.5 years. Thirty-six subjects (41.7%) were seropositive for HBsAg while 24 (27.9%) were seropositive for Hepatitis C Virus (HCV) antibody. The mean alpha fetoprotein level was 359 ± 9.9 ng/mL while mean control value was 1.93 ± 0.24 ng/mL. Liver function test parameters were elevated compared with control subjects (P < 0.001). The increase in serum alpha-fetoprotein was higher (P < 0.001) in HCV than HBsAg positive patients.

Conclusion:

Serum alpha-fetoprotein level was highest in HCV compared to HBsAg positive and hepatitis negative patients with CLD.
