Urinary schistosomiasis on Pemba Island: low-cost diagnosis for control in a primary health care setting

In the 1970s and early 1980s indirect diagnosis of urinary schistosomiasis, using urinalysis reagent strips for proteinuria and haematuria, was proposed as a possible alternative to the more accurate but very time-consuming parasitological methods. The recent experience o f the Schistosomiasis Control Programme for Pemba Island, which used a combination of (1) observations o f grossly bloody urine specimens, (2) results from reagent strips for measuring haematuria, and (3) treatment with praziquantel, is the first large-scale example o f a simple, inexpensive and promising alternative for controlling the morbidity caused by this parasite.     

Oral health care in private and small long-term care facilities: a qualitative study

Objective: Elderly people who are institutionalised receive qualified care. Among the services supplied, oral health care has not always been a priority. The aim of this study was to identify the characteristics of oral health care provided to the elderly residents in long‐term care facilities (LTC) in Porto Alegre/RS city. Methods: Twelve private and small‐size LTCs (less than 20 residents) participated in this study. All supervisors and 36 carers were interviewed. The data obtained were organised according to the offer of oral health under the following categories: responsibility for oral care, oral care routines, difficulties carrying out oral care routines. Results: The procedures used most often in order of frequency were tooth brushing, prostheses cleaning, use of mouthwashes, soaking of prostheses and cleaning of the tongue. Among the difficulties mentioned were the high cost of dental assistance, the lack of co‐operation both by family members and by the elderly themselves, the oral and general health status of the elderly and the limited time available for carers to carry out the tasks. Oral care is conducted empirically, and the responsibility is left to the carers. Conclusions: Analysis of the statements given reveals that oral care does not follow any kind of protocol or standardisation. The persistence of this situation could lead to unsatisfactory oral health care in private and small LTC facilities.     

Counselling in a general practice setting: controlled study of health visitor intervention in treatment of postnatal depression.

OBJECTIVE--To determine whether counselling by health visitors is helpful in managing postnatal depression. DESIGN--Controlled, random order trial. SETTING--Health centres in Edinburgh and Livingston. PATIENTS--Sixty women identified as depressed by screening at six weeks post partum and by psychiatric interview at about 13 weeks post partum. Five women did not wish to participate, and a further five did not complete the trial. Age, social and obstetric factors, and diagnosis were similar in women who completed the trial and those who withdrew. INTERVENTION--Eight weekly counselling visits by health visitors who had been given a short training in counselling for postnatal depression. END POINT--Reduction of depression. MEASUREMENTS and main results--Standardised psychiatric interviews and a 10 point self report scale were used to identify depression before and after intervention. The psychiatrist was not told to which group women were allocated. After three months 18 (69%) of the 26 women in the treatment group had fully recovered compared with nine (38%) of the 24 in the control group. The difference between the groups was thus 32% (95% confidence interval 5 to 58). CONCLUSIONS--Counselling by health visitors is valuable in managing non-psychotic postnatal depression.     

Utilization of herpes simplex PCR assays for cerebrospinal fluid in a pediatric health care setting

An assessment was made of the utilization and impact of a diagnostic polymerase chain reaction (PCR) assay for the diagnosis of herpes simplex viruses (HSV) 1 and 2 in cerebrospinal fluid of children who attended a Canadian pediatric referral centre. One hundred and three assays were performed on specimens from 103 patients during the period August 1997 to September 1998. Patient ages ranged from newborn to 16 years. Indications for HSV PCR included seizures with or without fever (56.3%), aseptic meningitis (16.5%), and encephalopathy with or without fever (10.7%). Only 2 of 103 (1.9%) assays were positive, including one each for HSV1 and HSV2. Control specimens that were seeded with virus indicated inhibition for 24.3, 8.8, and 6.8% of assays for HSV1, HSV2, and both HSV1 and HSV2, respectively. The mean turn-around time for HSV PCR was 2.5 days, and 90.3% were completed in less than 5 days. Acyclovir was administered to 78.6% of the patients overall; the results of the HSV PCR impacted on the treatment courses for 36 individuals. Nevertheless, 16.5% of patients continued to receive extended courses of antiviral therapy despite negative HSV PCR assays. Although it is desirable to decrease the frequency of PCR inhibitions and to further decrease the interval to assay completion, HSV PCR does have a significant impact on antiviral use in this setting.     

The social network around influenza vaccination in health care workers: a cross-sectional study

Background

Influenza vaccination coverage remains low among health care workers (HCWs) in many health facilities. This study describes the social network defined by HCWs’ conversations around an influenza vaccination campaign in order to describe the role played by vaccination behavior and other HCW characteristics in the configuration of the links among subjects.

Methods

This study used cross-sectional data from 235 HCWs interviewed after the 2010/2011 influenza vaccination campaign at the Hospital Clinic of Barcelona (HCB), Spain. The study asked: “Who did you talk to or share some activity with respect to the seasonal vaccination campaign?” Variables studied included sociodemographic characteristics and reported conversations among HCWs during the influenza campaign. Exponential random graph models (ERGM) were used to assess the role of shared characteristics (homophily) and individual characteristics in the social network around the influenza vaccination campaign.

Results

Links were more likely between HCWs who shared the same professional category (OR 3.13, 95% CI?=?2.61–3.75), sex (OR 1.34, 95% CI?=?1.09–1.62), age (OR 0.7, 95% CI?=?0.63–0.78 per decade of difference), and department (OR 11.35, 95% CI?=?8.17–15.64), but not between HCWs who shared the same vaccination behavior (OR 1.02, 95% CI?=?0.86–1.22). Older (OR 1.26, 95% CI?=?1.14–1.39 per extra decade of HCW) and vaccinated (OR 1.32, 95% CI?=?1.09–1.62) HCWs were more likely to be named.

Conclusions

This study finds that there is no homophily by vaccination status in whom HCWs speak to or interact with about a workplace vaccination promotion campaign. This result highlights the relevance of social network analysis in the planning of health promotion interventions.
