Opportunities and barriers to effective operation and maintenance of public toilets in informal settlements: perspectives from toilet operators in Kampala

Although classified by the Joint Monitoring Programme (JMP) as unimproved sanitation facilities, public toilets still play a critical role in eliminating open defecation in informal settlements. We explored perspectives of toilet operators on opportunities and barriers to operation and maintenance (O&M) of public toilets in informal settlements. A cross-sectional study design was used. Up to 20 in-depth interviews were used to obtain data on the experiences of public toilet operators. Thematic content analysis was used.

Ressults show that opportunities for improving O&M include; operation of public toilets is a source of livelihood; operators are knowledgeable on occupational risks, and the community is involvedin sanitation activities. Barriers to effective O&M include; high operation costs, failure to break even and a lack of investments in occupational health Therefore, there is need to recognise the significance of public toilets as a viable alternative to open defecation in areas where ownership of private sanitation facilities is difficult. Failure to observe the health and safety of toilet operators may further compromise O&M.     

Atrial fibrillation, ischaemic heart disease, and the risk of death in patients with heart failure.

AIMS: Atrial fibrillation (AF) is a risk factor for death in patients with a myocardial infarction, but highly variable results are reported in patients with heart failure. We studied the prognostic impact of AF in heart failure patients with and without ischaemic heart disease. METHODS AND RESULTS: During a period of 2 years, 3587 patients admitted to hospital because of heart failure were included in this study. All patients were examined by echocardiography and the presence of AF was recorded. Follow-up was available for 8 years. Twenty four percent of those discharged alive from hospital had AF. After 4 and 8 years of follow-up, mortality was higher in patients with AF than in patients without, 56 vs. 52% and 77 vs. 73%, respectively. Cox multivariable regression analysis showed a small but significant importance of AF for long-term mortality [hazard ratio (HR) 1.12, 95% confidence limits (CI), 1.02-1.23, P=0.018]. There was a significant interaction between the importance of AF and the presence of ischaemic heart disease (P=0.034). In patients with AF at the time of discharge and ischaemic heart disease, HR was 1.25 (95% CI: 1.09-1.42) and P<0.001; in patients with AF at discharge and without ischaemic heart disease, HR was 1.01 (95% CI: 0.88-1.16) and P=0.88. CONCLUSION: AF is associated with increased risk of death only in patients with ischaemic heart disease. This finding may explain the variable results of studies of the prognosis associated with AF in heart failure.     

Electromyography Before and After Treatment of TMJ Dysfunction

The patient described in this article suffered from pain in the right side of her face for five years before she saw the authors. Earlier treatment with medication and neurosurgery had not been successful. The authors used electromyography to examine the disturbed muscle function and to investigate a possible cause for the pain in the muscles of mastication. The silent periods of the patient's muscles were measured before and after treatment, since it is known from the literature that the EMG silent periods may be elongated in patients with TMJ dysfunction or occlusal irregularities. The coordination of both heads of this patient's lateral pterygoid muscles were bilaterally investigated before and after treatment. Treatment consisted of splint therapy and selective grinding. Oral rehabilitation was also undertaken, beginning three months after the disappearance of the patient's symptoms.     

Severe complex regional pain syndrome type II after radial artery harvesting

The radial artery is increasingly used as a coronary bypass graft. We report on a patient who developed a severe complex regional pain syndrome type II--also called causalgia--after radial artery harvesting. After an odyssey of diagnostic and presumed therapeutic procedures, she underwent surgical revision of the left forearm. Intraoperatively, a titanium clip in close neighborhood to the superficial radial nerve affecting the perineurium was found and removed, and more distally, a small neurinoma (3 by 4 mm) was resected. Despite presumed successful operation, symptoms did not improve. The patient presumably remains unable to use her left arm and hand.     

Bronchogenic cyst —cause of refractory wheezing in infancy

A 11/2-year-old male child with past history of recurrent wheezing presented with a severe and refractory episode following a peanut aspiration. A bronchoscopy was done and the peanut removed. However, as the wheezing persisted a detailed evaluation was done which revealed a bronchogenic cyst. Surgical excision of the cyst was done and the child improved symptomatically. Congenital lesions need to be ruled out in infants and children with persistent and refractory wheezing     

Biapical cannulation for biventricular support with the pneumatically driven Excor system

We report on a 41-year old patient who underwent implantation of an Excor biventricular assist system. Both ventricles were cannulated on the apical aspect with left ventricular apex cannulas. The cannulation technique is described.     

Clinical quality indicators of venous leg ulcers: development, feasibility, and reliability

In the clinical setting, diagnosis and treatment of venous leg ulcers can vary considerably from patient to patient. The first step to reducing this variation is to document venous leg ulcer care through use of quantitative scientific documentation principles. This requires the development of valid and reliable evidence-based quality indicators of venous leg ulcer care. A Scandinavian multidisciplinary, cross-sectional panel of wound healing experts developed clinical quality indicators on the basis of scientific evidence from the literature and subsequent group nominal consensus of the panel; an independent medical doctor tested the feasibility and reliability of these clinical indicators, assessing the quality of medical technical care on 100 consecutive venous leg ulcer patients. Main outcome measures were healing, recurrence, pain, venous disease diagnosis, differential diagnosis and treatment, and inter- and intra-rater reliability. The indicators proved feasible and reliable to measure (inter-rater kappa = 0.79, P < 0.01 and intra-rater kappa = 0.89, P < 0.1). Within 3 months of initial examination, venous etiology was verified by duplex in 61 of the 98 participating patients (62%) and 31 (32%) were assessed for venous surgery. Distal arterial pressure was measured following initial examination in 33 of the patients (34%). All patients (100%) were prescribed compression therapy. Of the 98 patients, 11 (11%) had ulcers recur in 3 months and 72 (73%) healed in 12 months, which is in line with the literature. It is feasible to reliably measure the quality of medical technical venous leg ulcer care in the clinical setting using a few strategic clinically relevant indicators of quality.
