Are hospitals prepared to support newborn survival? – an evaluation of eight first‐referral level hospitals in Kenya*

Objective To assess the availability of resources that support the provision of basic neonatal care in eight first‐referral level (district) hospitals in Kenya. Methods We selected two hospitals each from four of Kenya’s eight provinces with the aim of representing the diversity of this part of the health system in Kenya. We created a checklist of 53 indicator items necessary for providing essential basic care to newborns and assessed their availability at each of the eight hospitals by direct observation, and then compared our observations with the opinions of health workers providing care to newborns on recent availability for some items, using a self‐administered structured questionnaire. Results The hospitals surveyed were often unable to maintain a safe hygienic environment for patients and health care workers; staffing was insufficient and sometimes poorly organised to support the provision of care; some key equipment, laboratory tests, drugs and consumables were not available while patient management guidelines were missing in all sites. Conclusion Hospitals appear relatively poorly prepared to fill their proposed role in ensuring newborn survival. More effective interventions are needed to improve them to meet the special needs of this at‐risk group.     

Hydrocelectomy: a proxy for hydrocele prevalence in coastal Kenya

To assess the value of hydrocelectomy as an indicator of the prevalence of lymphatic filariasis, the frequency of hydrocelectomy was investigated in five hospitals in an area of coastal Kenya where filariasis is endemic. Two of the hospitals studied (Kinango and Msambweni) were in Kwale district, two (Kilifi and Malindi) in Kilifi district and one (the Coast Provincial General Hospital) in Mombasa. Surgical operations performed between January 1991 and August 1993 were tallied from the main theatre registers. Additionally, admission files for hydrocelectomy patients were examined prospectively between September 1993 and February 1994, to obtain age profiles. Hydrocelectomies accounted for 27.6%, 16.6%, 13.6%, 4.3% and 2.0% of the major operations (totalling 6339) recorded in Kinango, Msambweni, Kilifi, Malindi and Coast Provincial General Hospital, respectively. The proportion of operations involving hydrolectomy was significantly higher in the two hospitals in Kwale district, in the southern part of the study area, than in the two hospitals in Kilifi district, in the northern part (23.4%, with 95% confidence intervals of 20.9%-25.9%, v. 10.3%, with 95% confidence intervals of 8.7%-11.9%; P < 0.001). The generally high frequencies of hydrocelectomy in the study area are evidence of the heavy social and economic burden imposed by hydrocele-attributable morbidity and its management. The age distribution pattern of the hydrocelectomy patients paralleled that of the individuals with hydrocele in the surrounding area.     

Role of antispasmodics in the treatment of irritable bowel syndrome

Irritable bowel syndrome (IBS) is a long-lasting, relapsing disorder characterized by abdominal pain/discomfort and altered bowel habits. Intestinal motility impairment and visceral hypersensitivity are the key factors among its multifactorial pathogenesis, both of which require effective treatment. Voltage-gated calcium channels mediate smooth muscle contraction and endocrine secretion and play important roles in neuronal transmission. Antispasmodics are a group of drugs that have been used in the treatment of IBS for decades. Alverine citrate, a spasmolytic, decreases the sensitivity of smooth muscle contractile proteins to calcium, and it is a selective 5-HT_1A receptor antagonist. Alverine, in combination with simethicone, has been demonstrated to effectively reduce abdominal pain and discomfort in a large placebo-controlled trial. Mebeverine is a musculotropic agent that potently blocks intestinal peristalsis. Non-placebo-controlled trials have shown positive effects of mebeverine in IBS regarding symptom control; nevertheless, in recent placebo-controlled studies, mebeverine did not exhibit superiority over placebo. Otilonium bromide is poorly absorbed from the GI tract, where it acts locally as an L-type calcium channel blocker, an antimuscarinic and a tachykinin NK2 receptor antagonist. Otilonium has effectively reduced pain and improved defecation alterations in placebo-controlled trials in IBS patients. Pinaverium bromide is also an L-type calcium channel blocker that acts locally in the GI tract. Pinaverium improves motility disorders and consequently reduces stool problems in IBS patients. Phloroglucinol and trimethylphloroglucinol are non-specific antispasmodics that reduced pain in IBS patients in a placebo-controlled trial. Antispasmodics have excellent safety profiles. T-type calcium channel blockers can abolish visceral hypersensitivity in animal models, which makes them potential candidates for the development of novel therapeutic agents in the treatment of IBS.     

Implementation of a structured paediatric admission record for district hospitals in Kenya – results of a pilot study

Background  

The structured admission form is an apparently simple measure to improve data quality. Poor motivation, lack of supervision, lack of resources and other factors are conceivably major barriers to their successful use in a Kenyan public hospital setting. Here we have examined the feasibility and acceptability of a structured paediatric admission record (PAR) for district hospitals as a means of improving documentation of illness.     

Detection of virulence-related genes by multiplex PCR in multidrug-resistant diarrhoeagenic Escherichia coli isolates from Kenya and Japan

We compared serotypes, drug susceptibility and presence of virulence-related genes in diarrhoeagenic Escherichia coli isolates from children < 5 years from Kenya (n = 82) and Japan (n = 47). Multiplex PCR was used to detect genes coding for enteroaggregative adherence (aggR), heat-stable toxin (st), heat-labile toxin (It), verotoxin (vt), attaching and effacing mechanism (eaeA), enteroaggregative E. coli heat-stable enterotoxin 1 (astA) and enteroinvasive mechanism (invE). Kenyan E. coli O-serotypes were more diverse than those from Japan (29 vs. 12 serotypes) and exhibited high level multidrug resistance to World Health Organization (WHO) recommended antibiotics. Resistance rates to tetracycline, ampicillin and sulphamethoxazole-trimethoprim were 70.7, 65.9 and 68.3% respectively, but resistance to sulphamethoxazole-trimethoprim among the E. coli isolates from Japan was low (21%). Kenyan isolates harboured virulence-related genes in high frequency (82.9%) compared to those from Japan (25.5%) with aggR and astA being the most frequently detected genes. The presence of multiple virulence genes was associated with multidrug resistance and this merits further investigation.     

Psychosocial issues in adolescents with cancer

Cancer in adolescents is uncommon and when it occurs raises a number of unique challenges for both the patient and their families. Adolescence is a period of time of significant physical and emotional changes and a diagnosis of cancer during this time has a major impact on their psychological and physical development. In this review we will look at the psychosocial issues facing adolescents who have cancer. We will address adolescent development, issues related to informed consent and assent, initial responses to the diagnosis of cancer, quality of life and the experience of the adolescent with cancer, psychological adjustment, support systems, body image issues, sexuality, education, hope, and treatment compliance.     

Single nucleotide polymorphisms in nucleotide excision repair genes,cancer treatment,and head and neck cancer survival

Purpose

Head and neck cancers (HNC) are commonly treated with radiation and platinum-based chemotherapy, which produce bulky DNA adducts to eradicate cancerous cells. Because nucleotide excision repair (NER) enzymes remove adducts, variants in NER genes may be associated with survival among HNC cases both independently and jointly with treatment.

Methods

Cox proportional hazards models were used to estimate race-stratified (White, African American) hazard ratios (HRs) and 95 % confidence intervals for overall (OS) and disease-specific (DS) survival based on treatment (combinations of surgery, radiation, and chemotherapy) and 84 single nucleotide polymorphisms (SNPs) in 15 NER genes among 1,227 HNC cases from the Carolina Head and Neck Cancer Epidemiology Study.

Results

None of the NER variants evaluated were associated with survival at a Bonferroni-corrected alpha of 0.0006. However, rs3136038 [OS HR = 0.79 (0.65, 0.97), DS HR = 0.69 (0.51, 0.93)] and rs3136130 [OS HR = 0.78 (0.64, 0.96), DS HR = 0.68 (0.50, 0.92)] of ERCC4 and rs50871 [OS HR = 0.80 (0.64, 1.00), DS HR = 0.67 (0.48, 0.92)] of ERCC2 among Whites, and rs2607755 [OS HR = 0.62 (0.45, 0.86), DS HR = 0.51 (0.30, 0.86)] of XPC among African Americans were suggestively associated with survival at an uncorrected alpha of 0.05. Three SNP-treatment joint effects showed possible departures from additivity among Whites.

Conclusions

Our study, a large and extensive evaluation of SNPs in NER genes and HNC survival, identified mostly null associations, though a few variants were suggestively associated with survival and potentially interacted additively with treatment.
