Hepatitis C virus infection and related liver disease in children of mothers with antibodies to the virus

Objective: To evaluate the clinical, biochemical, and virologic features associated with hepatitis C virus (HCV) infection acquired early in life from mothers with antibodies to HCV (anti-HCV).Study design: Multicenter prospective-retrospective study in Italian children.Patients: Two groups of children were investigated. Group 1 included 14 infants, born to mothers with anti-HCV but without human immunodeficiency virus infection, who became seropositive for HCV RNA during the first year of life and were thus considered infected. Group 2 included 16 children with chronic hepatitis C, aged 1 ½ to 14 years, whose mothers were the unique potential source of infection. Both groups were followed for 12 to 48 months.Methods: Alanine transaminase (ALT), anti-HCV, and HCV RNA were investigated by the polymerase chain reaction on entry to the study and during follow-up.Results: All children in group 1 had anti-HCV throughout follow-up, and all had ALT abnormalities, ranging from 1.5 to 10.5 times the normal value during the first 12 months. During further follow-up, 5 of 10 children had HCV RNA with abnormal ALT values, 3 had a return to normal of the ALT values but continued to have viremia, and 2 eventually had normal ALT values and clearance of HCV RNA. Of the 16 children in group 2, all were free of symptoms and 62% had only slight ALT elevations; 7 who underwent liver biopsy had histologic features of minimal or moderate hepatitis.Conclusions: HCV infection acquired early in life from mothers with anti-HCV is usually associated with biochemical features of liver damage during the first 12 months of life. Progression to chronicity seems to occur in the majority of cases, although HCV-associated liver disease is likely to be mild throughout infancy and childhood. (J Pediatr 1997;130:990-3)     

Quality of life in tuberculosis: Patient and provider perspectives

Tuberculosis (TB) is a persistent problem in the United States; however, little is known about its impact on functioning and quality of life (QOL) among people with TB. The purpose of this study is to describe the impact of TB on patients' QOL by using focus groups to assess the domains of QOL that are affected. Participants included patients (n = 10) who received treatment for active TB and physicians (n = 4) and nurses (n = 9) caring for patients with TB at a public health clinic in Baltimore, Maryland. TB affected all predicted domains of QOL, including general health perceptions, somatic sensation, psychological health, spiritual well-being, and physical, social and role functioning. Social stigmatization, isolation, pill burden, long duration of therapy, sexual dysfunction, loss of income, and fear were additional specific problems related to TB. Surprisingly, 11% (33) of the comments described benefits of TB illness, including increased spirituality and improved life perspectives. In addition, four additional QOL domains and three elements of treatment specific to TB which substantially impact QOL were identified. While patients and clinicians both identified issues in many areas of QOL, only patients mentioned the impact on sexual function, spirituality and improved life perspectives. Despite available curative therapy, TB and its treatment still have significant short and long-term consequences on patients' QOL.     

Epidemiology of Travelers— Diarrhea: Details of a Global Survey

Background Recent epidemiologic data on travelers— diarrhea (TD) are essential for the evaluation of conventional and future prophylactic and therapeutic measures.
Methods To determine the epidemiology, including risk factors, impact and quality-of-life evaluation of TD, a cross-sectional survey was conducted over 12 months at the airports of Mombasa (Kenya), Goa (India), Montego Bay (Jamaica) and Fortaleza (Brazil) by distributing questionnaires to visitors just prior to their flying home. The study period was March 1996 to July 1998.
Results Overall, 73,630 short-term visitors completed a questionnaire. The total diarrhea attack rate varied between a high of 54.6% in Mombasa and a low of 13.6% in Fortaleza, but only between 31.5% and 5.4% of all travelers had classic TD. The 14-day incidence rates varied between 19.5% and 65.7%. Few travelers meticulously avoided potentially dangerous food items, although in India and Kenya most travelers avoided those considered most dangerous. Risk factors were stays exceeding 1 week, age between 15 and 30 years, and residence in the UK. The impact, measured as incapacity or quality-of-life scores, was very considerable.
Conclusions TD continues to affect vacationers and business travelers as frequently as it did some 20 years ago. Compliance with recommendations to reduce exposure to pathogens by avoiding dangerous food items is poor among travelers from all countries. Implementation of food safety education programs may be difficult to achieve.

Factor Structure of the Urdu Version of the Spence Children's Anxiety Scale in Pakistan

Spence Children's Anxiety Scale (SCAS) is one of the most commonly used self-report questionnaires to measure symptoms of anxiety disorders in adolescents. Despite its common use, studies that examine the psychometric properties of SCAS in Pakistan is lacking. Therefore, the purpose of this study was to examine the psychometric properties of the Urdu translated version of the SCAS among adolescents in Pakistan. A total of 1277 students (708 boys and 569 girls), aged 13 to17 years, who had been recruited from 13 schools in Rawalpindi, Pakistan participated in the study. The mean overall anxiety score was significantly higher in girls than males on all the SCAS subscales except for obsessive compulsive disorder. The internal consistency of the Urdu SCAS was good. Confirmatory factor analyses supported six separate factor structures. Results of the study are discussed with reference to the sociocultural milieu of Pakistan and culture sensitive conceptualization of anxiety and its subtypes.
