ABSTRACT
BACKGROUND: Irritable bowel syndrome is a common gastrointestinal disorder, and its prevalence and demographics have been evaluated by different methodologies with varying results. AIM: To evaluate irritable bowel syndrome demographic and prevalence characteristics utilizing a web-enabled panel. METHODS: From an existing 150 000-member panel, 31 829 individuals were randomly selected and sent screening questionnaires to evaluate irritable bowel syndrome symptoms. Individuals who agreed to participate and completed the screening questionnaire received a second questionnaire related to a diagnosis of irritable bowel syndrome, a more detailed symptom description, and additional burden of illness data. RESULTS: Irritable bowel syndrome prevalence was 7%. Prevalence was higher in women vs. men, unmarried individuals vs. married individuals and unemployed individuals vs. employed individuals. Of those completing the second questionnaire, 51% had seen their physicians for irritable bowel syndrome symptoms in the past year and most had an episode within the past 3 months. During the past year, approximately half of the participants had used a prescription medication, and over 90% had used an over-the-counter medication for irritable bowel syndrome. Participants with irritable bowel syndrome demonstrated quality-of-life reductions relative to norms of the United States population. CONCLUSIONS: Web-enabled data collection represents a novel tool for rapidly surveying a large population of individuals with irritable bowel syndrome symptoms.

A longitudinal study was conducted over a 1-year period in six selected villages in Petauke and Katete districts in the Eastern Province of Zambia. Starting in November 1997, 50 animals were sampled at random at each village every 2 months. The parasitological prevalence of trypanosomosis was determined by the haematocrit centrifugation buffy-coat technique, supplemented with thick and thin Giemsa-stained blood films. Serum samples also were collected for anti-trypanosomal antibody determination by indirect enzyme-linked immunosorbent assay. Parasitological prevalence was highly variable between villages and between visits (range: 0-28.6%; median: 3.1%). Seroprevalence was also variable between villages (range: 0-80.8%; median: 50%), but was less variable between visits. Average annual parasitological prevalence and average annual seroprevalence for each village were highly correlated [R(2)(adjustedford.f.)=0.89, p<0.01]. Seroprevalence measured on any single visit to a study village was better than parasitological prevalence as a predictor of average annual parasitological prevalence.

Over a five year period, the South Carolina Health Connection Project has evolved to multi-site, multi-organization community-base collaborative initiative. From this project over $60,000.00 in funds have been secured. However, when costing the human resources and many other in-kind contributions involved in the SCHC Projects activities, the Project can modestly be valued at nearly $200,000.00. The efforts of a few have been shared with others, who also shared the resources with others, and the health promotion empowerment cycle continues. We believe the South Carolina Health Connection is an exemplary of a Community Health Promotion Partnership Model. We hope you will agree!

OBJECTIVE: The aim of this study was to evaluate the relationships between age, health status, access to care, and breast and cervical cancer screening among multiethnic elderly and nonelderly women. METHODS: A structured telephone survey of a quota sample of 1,420 New York City women from four Hispanic groups (Columbian, Dominican, Puerto Rican, Ecuadorian) and three black groups (U.S., Caribbean, and Haitian) was performed. Outcome measures included "ever" and "recent" self-reported use of mammography, clinical breast examination (CBE), and Pap smears. Logistic regression models assessed the predictors of screening use. RESULTS: Having a regular source of care significantly predicted all screening use for both elderly and nonelderly, controlling for ethnicity, sociodemographics, health status, access to care, proportion of life in the United States, and cancer attitudes. Elderly women (>/=65 years) were significantly less likely to have ever had (OR = 0.79, 95% CI 0.65-0. 96) and to have recently had (OR = 0.67, 95% CI 0.57-0.79) Pap smears than younger women, controlling for the other variables; being elderly also tended to be an independent predictor of ever and recent mammography and CBE use. Interestingly, there was a trend for health status to act differently in predicting Pap smear use for the two age groups. For younger women, being in poor health increased the odds of Pap smear screening, while for elderly women, being in good health increased the odds of screening. CONCLUSIONS: Elderly women reported being screened less than younger women; interactions between health status and age need further exploration.

The indirect enzyme-linked immunosorbent assay (ELISA) for the detection of anti-trypanosomal antibodies in bovine serum was adapted for use with dried blood spots on filter paper. Absorbance (450 nm) results for samples were expressed as percent positivity, i.e. percentage of the median absorbance result of four replicates of the strong positive control serum. The antibody-ELISA was evaluated in Zambia for use in epidemiological surveys of the prevalence of tsetse-transmitted bovine trypanosomosis. Known negative samples (sera, n = 209; blood spots, n = 466) were obtained from cattle from closed herds in tsetse-free areas close to Lusaka. Known positive samples (sera, n = 367; blood spots, n = 278) were obtained from cattle in Zambia's Central, Lusaka and Eastern Provinces, diagnosed as being infected with Trypanosoma brucei, T. congolense, or T. vivax using the phase-contrast buffy-coat technique or Giemsa-stained thick and thin blood smears. For sera (at a cut-off value of 23.0% positivity) sensitivity and specificity were 86.1 and 95.2%, respectively. For bloodspots (at a cut-off value of 18.8% positivity) sensitivity and specificity were 96.8 and 95.7%, respectively. The implications of persistence of antibodies following treatment or self-cure are discussed.

Optimal pain management is essential in blunt trauma patients sustaining significant chest trauma. The purpose of this randomized prospective trial was to measure the difference in pulmonary function in nonintubated patients with unilateral multiple rib fractures receiving two modalities of pain relief: systemic narcotic medications alone or local anesthetics given by intrapleural catheter (IPCs). Forty-two patients were randomized to receive systemic narcotic medications or IPCs for pain control. The patients with IPCs statistically had more compromised pulmonary function as measured by forced vital capacity (FVC) on admission; however, they tended toward a greater objective improvement of FVC on discharge. When analyzing a cohort of severely impaired patients (initial FVC < 20%), half of the systemic medication patients compared to only 10% of the IPC group failed and required another mode of therapy. Catheter complications were minor and did not contribute to overall morbidity. The IPC patients had fewer failures than the systemic medication patients.

We report on 14 patients with instability of the cervical spine secondary to rheumatoid arthritis treated by fusion using a combination of traditional bone grafting techniques and methylmethacrylate bone cement. Successful fusion was achieved in all cases with few complications. The high infection rate reported by other authors was avoided by reducing the bulk of the cement mass and the use of antibiotic impregnated cement. We recommend this method of fusion to all orthopaedic surgeons involved in the treatment of patients with rheumatoid arthritis.

The radiolabeled monoclonal antibody 791T/36 raised against a human osteosarcoma was injected into 20 patients with known or suspected bone tumors. Gamma camera images were acquired at 48 or 72 hours after injection, and assessed for antibody localization. Positive images were obtained in all five osteosarcomas and four other primary malignant sarcomas. Two of the four other primary bone tumors gave positive images. Three patients with trauma had negative images as did one patient with Paget's disease. Two patients with suppurative disease gave positive images. The antibody localized in the majority of malignant sarcomas tested. In one tumor where tissue was available, a tumor:non-tumor ratio of 2.8:1 was measured. Repeat imaging was performed in five patients. Immunoscintigraphy using the monoclonal antibody 791T/36 has shown tumor localization in patients with bone and soft tissue sarcomas.

Immunoscintigraphy using radioisotope-labelled monoclonal antibody prepared against osteosarcoma 791T cells was used to detect a primary osteosarcoma. The eight-centimetre tumour was detected using rectilinear scintigraphy of 131I-labelled antibodies. Image enhancement was achieved by subtraction of blood-pool radioactivity labelled with technetium-99m. The ratio of tumour to non-tumour uptake of radioactivity (5:1) suggested that antibody targeting of therapeutic agents is feasible.

A study was conducted to evaluate the result of treating closed fractures of the femoral shaft by simple traction in a busy General Hospital with a view to reducing some of te complications experienced in conventional traction splintage devices and to obtaining early discharge from hospital. Functional bracing was used when possible for fractures in the middle of the shaft. Over a two-year-period 45 patients were studied. The preliminary findings indicate that simple skeletal traction applied to fractures of the shaft of the femur gives satisfactory results, reduces the complications of conventional management in a Thomas's splint and shortens the time in hospital. Supplementary functional bracing applied between the fourth and seventh weeks allows this earlier discharge.
