Infantile hypertrophic pyloric stenosis: a single institution’s experience

Background/purpose Infantile hypertrophic pyloric stenosis (IHPS) is said to be relatively common in the western world, but its incidence in the Kingdom of Saudi Arabia is unknown. We set out to study the incidence of IHPS in children presenting at our hospital and review the clinical presentation and treatment outcomes of such patients.Patients and methods A retrospective chart review of all cases with IHPS admitted to a tertiary hospital, Riyadh Military Hospital, over 18 years (1990–2008) was conducted. Diagnosis was confirmed by ultrasonography according to the length of the pyloric channel and thickness of the pyloric muscles. An analysis of demographic data, clinical presentation, diagnostic modality, and associated congenital anomalies was carried out. Operative technique, postoperative course, and complication rates were identified.Results The review of the medical records showed 22 patients with a diagnosis of IHPS. The incidence rate of IHPS was 1.4/10 000 live births. Demographically, most cases presented in the first month of life. It is more common in boys. In all, 55% of infants were first borns. Clinically, nonbilious projectile vomiting was the main symptom. Mild dehydration was found in half of the cases with alkalotic changes. Ultrasonography was the main diagnostic modality in 82% of cases. Others were diagnosed by contrast study. Open Ramstedt pyloromyotomy was the surgical approach in 20 (91%) cases and the laparoscopic approach in 2 cases (9%). Fourteen (14%) patients had an associated congenital inguinal hernia. The mean length of hospital stay was 5.5 days. The most common postoperative complication was wound infection in 4.5% of patients. Incidence of IHPS had obvious seasonal association.Conclusion Incidence of IHPS at our hospital (the biggest hospital in the Kingdom of Saudi Arabia with an annual birth record of 14 000) is far less common than international incidences reported in North America and Europe. More reports from Saudi Arabia, the Middle East, and Asia are recommended to support the rarity of IHPS in this region of the world. Seasonal variation suggests a possible etiological role for environmental factors. It is of practical use for both epidemiologists and clinicians for future comparability.Keywords: incidence, infantile pyloric stenosis, risk factor

Self-reported use of anti-malarial drugs and health facility management of malaria in Ghana

<p>Abstract</p> <p>Objective</p> <p>To assess the appropriateness of self-reported use of anti-malarial drugs prior to health facility attendance, and the management of malaria in two health facilities in Ghana.</p> <p>Method</p> <p>A structured questionnaire was used to collect data from 500 respondents who were diagnosed clinically and/or parasitologically for malaria at Agogo Presbyterian Hospital and Suntreso Polyclinic, both in the Ashanti Region of Ghana. Collected information included previous use of anti-malarial drugs prior to attending the health facilities, types of drugs used, how the drugs were used, and the sources of the drugs. In addition, the anti-malarial therapy given and outcomes at the two health facilities were assessed.</p> <p>Results</p> <p>Of the 500 patients interviewed, 17% had severe malaria, 8% had moderate to severe malaria and 75% had uncomplicated malaria. Forty three percent of the respondents had taken anti-malarial drugs within two weeks prior to hospital attendance. The most commonly used anti-malarials were chloroquine (76%), sulphadoxine-pyrimethamine (9%), herbal preparations (9%) and amodiaquine (6%). The sources of these medicines were licensed chemical sellers (50%), pharmacies (21%), neighbouring clinics (9%) or "other" sources (20%) including left-over medicines at home. One hundred and sixty three (77%) of the 213 patients who had used anti-malarial drugs prior to attending the health facilities, used the drugs inappropriately. At the health facilities, the anti-malarials were prescribed and used according to the national standard treatment guidelines with good outcomes.</p> <p>Conclusion</p> <p>Prevalence of inappropriate use of anti-malarials in the community in Ghana is high. There is need for enhanced public health education on home-based management of malaria and training for workers in medicine supply outlets to ensure effective use of anti-malaria drugs in the country.</p

The Role of Individual Variables, Organizational Variables and Moral Intensity Dimensions in Libyan Management Accountants’ Ethical Decision Making

This study investigates the association of a broad set of variables with the ethical decision making of management accountants in Libya. Adopting a cross-sectional methodology, a questionnaire including four different ethical scenarios was used to gather data from 229 participants. For each scenario, ethical decision making was examined in terms of the recognition, judgment and intention stages of Rest’s model. A significant relationship was found between ethical recognition and ethical judgment and also between ethical judgment and ethical intention, but ethical recognition did not significantly predict ethical intention—thus providing support for Rest’s model. Organizational variables, age and educational level yielded few significant results. The lack of significance for codes of ethics might reflect their relative lack of development in Libya, in which case Libyan companies should pay attention to their content and how they are supported, especially in the light of the under-development of the accounting profession in Libya. Few significant results were also found for gender, but where they were found, males showed more ethical characteristics than females. This unusual result reinforces the dangers of gender stereotyping in business. Personal moral philosophy and moral intensity dimensions were generally found to be significant predictors of the three stages of ethical decision making studied. One implication of this is to give more attention to ethics in accounting education, making the connections between accounting practice and (in Libya) Islam. Overall, this study not only adds to the available empirical evidence on factors affecting ethical decision making, notably examining three stages of Rest’s model, but also offers rare insights into the ethical views of practising management accountants and provides a benchmark for future studies of ethical decision making in Muslim majority countries and other parts of the developing world

Monocytes and neutrophils expressing myeloperoxidase occur in fibrous caps and thrombi in unstable coronary plaques

<p>Abstract</p> <p>Background</p> <p>Myeloperoxidase (MPO) -containing macrophages and neutrophils have been described at sites of plaque rupture. The presence of these cells in precursor lesions to acute rupture (thin cap atheroma, or vulnerable plaque) and within thrombi adjacent to ruptures has not been described, nor an association with iron-containing macrophages within unstable plaques.</p> <p>Methods</p> <p>We studied 61 acute ruptures, 15 organizing ruptures, 31 thin cap fibroatheromas, and 28 fibroatheromas from 72 sudden coronary death victims by immunohistochemical and histochemical techniques. Inflammatory cells were typed with anti-CD68 (macrophages), anti-BP-30 (neutrophil bactericidal glycoprotein), and anti-MPO. Iron was localized by Mallory's Prussian blue stain. In selected plaques alpha smooth muscle actin (DAKO, Carpinteria, CA, clone M0851) was performed.</p> <p>Results</p> <p>MPO positive cells were present in 79% of ruptured caps, 28% of thin cap fibroatheroma, and no fibroatheromas; neutrophils were present in 72% of ruptures, 8% of thin cap fibroatheromas, and no fibroatheromas. Iron containing foam cells were present in the caps of 93% of acute ruptures, of 85% of organizing ruptures, 20% of thin cap atheromas, and 10% of fibroatheromas. MPO positive cells were more frequent in occlusive than non-occlusive thrombi adjacent to ruptures (p = .006) and were more numerous in diabetics compared to non-diabetics (p = .002)</p> <p>Conclusion</p> <p>Unstable fibrous caps are more likely to contain MPO-positive cells, neutrophils, and iron-containing macrophages than fibrous caps of stable fibroatheromas. MPO-positive cells in thrombi adjacent to disrupted plaques are associated with occlusive thrombi and are more numerous in diabetic patients.</p

The effect of household heads training on long-lasting insecticide-treated bed nets utilization: a cluster randomized controlled trial in Ethiopia

<p>Abstract</p> <p>Background</p> <p>Long-lasting insecticide-treated bed nets (LLITN) have demonstrated significant impact in reducing malaria-related childhood morbidity and mortality. However, utilization of LLITN by under-five children is not satisfactory in many sub-Saharan African countries due to behavioural barriers. Previous studies had focused on the coverage and ownership of LLITN. The effect of skill-based training for household heads on LLITN utilization had not yet been investigated. A cluster-randomized trial on the effect of training of household heads on the use of LLITN was done in Ethiopia to fill this knowledge gap.</p> <p>Methods</p> <p>The study included 22 (11 intervention and 11 control) villages in southwest Ethiopia. The intervention consisted of tailored training of household heads about the proper use of LLITN and community network system. All households in each group received free LLITN. Data were collected at baseline, six and 12 months of the follow up periods. Utilization of LLITN in the control and intervention villages was compared at baseline and follow up periods.</p> <p>Results</p> <p>A total of 21,673; 14,735 and 13,758 individuals were included at baseline, sixth and twelfth months of the project period. At the baseline survey, 47.9% of individuals in the intervention villages and 68.4% in the control villages reported that they had utilized LLITN the night before the survey. At the six month, 81.0% of individuals in the intervention villages and 79.3% in the control villages had utilized LLITN. The utilization of LLITN in all age groups in the intervention villages was increased by 17.7 percentage point (95% CI 9.7-25.6) at sixth month and by 31.0 percentage point (95% CI 16.9-45.1) at the twelfth month. Among under-five children, the LLITN utilization increased by 31.6 percentage point (95% CI 17.3-45.8) at the sixth month and 38.4 percentage point (95% CI 12.1-64.7) at the twelfth months of the project period.</p> <p>Conclusion</p> <p>Household level skill-based training has demonstrated a marked positive effect in the utilization of LLITN. The effect of the intervention steadily increased overtime. Therefore, distribution of LLITN should be accompanied by a skill-based training of household heads to improve its utilization.</p> <p>Trail registration</p> <p>Australian New Zealand Clinical Trials Registry (ACTR number: <a href="http://www.anzctr.org.au/ACTRN12610000035022.aspx">ACTRN12610000035022</a>).</p

The effect of household heads training about the use of treated bed nets on the burden of malaria and anaemia in under-five children: a cluster randomized trial in Ethiopia

<p>Abstract</p> <p>Background</p> <p>Long-lasting insecticide-treated bed nets (LLITN) have demonstrated a significant effect in reducing malaria-related morbidity and mortality. However, barriers on the utilization of LLITN have hampered the desired outcomes. The aim of this study was to assess the effect of community empowerment on the burden of malaria and anaemia in under-five children in Ethiopia.</p> <p>Methods</p> <p>A cluster randomized trial was done in 22 (11 intervention and 11 control) villages in south-west Ethiopia. The intervention consisted of tailored training of household heads about the proper use of LLITN and community network system. The burden of malaria and anaemia in under-five children was determined through mass blood investigation at baseline, six and 12 months of the project period. Cases of malaria and anaemia were treated based on the national protocol. The burden of malaria and anaemia between the intervention and control villages was compared using the complex logistic regression model by taking into account the clustering effect. Eight Focus group discussions were conducted to complement the quantitative findings.</p> <p>Results</p> <p>A total of 2,105 household heads received the intervention and the prevalence of malaria and anaemia was assessed among 2410, 2037 and 2612 under-five children at baseline, six and 12 months of the project period respectively. During the high transmission/epidemic season, children in the intervention arm were less likely to have malaria as compared to children in the control arm (OR = 0.42; 95%CI: 0.32, 0.57). Symptomatic malaria also steadily declined in the intervention villages compared to the control villages in the follow up periods. Children in the intervention arm were less likely to be anaemic compared to those in the control arm both at the high (OR = 0.84; 95%CI: 0.71, 0.99)) and low (OR = 0.73; 95%CI: 0.60, 0.89) transmission seasons.</p> <p>Conclusion</p> <p>Training of household heads on the utilization of LLITN significantly reduces the burden of malaria in under-five children. The Ministry of Health of Ethiopia in collaboration with other partners should design similar strategies in high-risk areas to control malaria in Ethiopia.</p> <p>Trial registration</p> <p>Australia and New Zealand Clinical Trials Register (ANZCTR): <a href="http://www.anzctr.org.au/ACTRN12610000035022.aspx">ACTRN12610000035022</a></p
