Erysipelothrix rhusiopathiae endocarditis diagnosed by broad range 16s rRNA PCR gene sequencing.

Erysipelothrix rhusiopathiae (E. rhusiopathiae) is a rare occupational opportunistic Gram-positive bacillus. Infections caused by E. rhusiopathiae are principally a sequel of occupational and recreational exposures to infected animals. Infective endocarditis is a classic, albeit it infrequent, manifestation of invasive infection with this bacterium. We present a case of E. rhusiopathiae mitral valve endocarditis in a farmer with psoriasis presented with acute intractable heart failure requiring valve replacement surgery. E. rhusiopathiae was identified by 16S rRNA-based gene sequencing from culture-negative, surgically excised mitral valve leaflets.

Transplant tourism and invasive fungal infection.

BACKGROUND: Deceased and live-related renal transplants (RTXs) are approved procedures that are performed widely throughout the world. In certain regions, commercial RTX has become popular, driven by financial greed. METHODS: This retrospective, descriptive study was performed at the Royal Hospital from 2013 to 2015. Data were collected from the national kidney transplant registry of Oman. All transplant cases retrieved were divided into two groups: live-related RTX performed in Oman and commercial-unrelated RTX performed abroad. These groups were then divided again into those with and without evidence of fungal infection, either in the wound or renal graft. RESULTS: A total of 198 RTX patients were identified, of whom 162 (81.8%) had undergone a commercial RTX that was done abroad. Invasive fungal infections (IFIs) were diagnosed in 8% of patients who had undergone a commercial RTX; of these patients, 76.9% underwent a nephrectomy and 23.1% continued with a functioning graft. None of the patients with RTXs performed at the Royal Hospital contracted an IFI. The most common fungal isolates were Aspergillus species (including Aspergillus flavus, Aspergillus fumigatus, Aspergillus nidulans, and Aspergillus nigricans), followed by Zygomycetes. However, there was no evidence of fungal infection including Aspergillus outside the graft site. Computed tomography (CT) findings showed infarction of the graft, renal artery thrombosis, aneurysmal dilatation of the external iliac artery, fungal ball, or just the presence of a perigraft collection. Of the total patients with IFIs, 23.1% died due to septic shock and 53.8% were alive and on hemodialysis. The remaining 23.1% who did not undergo nephrectomy demonstrated acceptable graft function. CONCLUSIONS: This is the largest single-center study on commercial RTX reporting the highest number of patients with IFI acquired over a relatively short period of time. Aspergillus spp were the main culprit fungi, with no Candida spp being isolated. A high index of suspicion might be the most reasonable means to reduce the possible very poor outcomes. Improving legal transplant programs and strengthening the associated laws could prevent commercial transplant tourism.

Nurses' perceptions of the challenges related to the Omanization policy.

BACKGROUND: Human resource development has become a major concern in Oman since the inception of the 'Omanization' policy in 1988. The main goal of this policy was to replace the expatriate nursing workforce with similarly qualified local nurses to develop a sustainable workforce and achieve self-reliance. AIM: The aim of this study is to explore the nurses' perceptions of Omanization policy. METHODS: A qualitative research design was used and 16 Omani registered nurses and 26 student nurses were interviewed in depth. Transcribed data were analysed using content analysis. RESULTS: Two main themes emerged from the data: 'Challenges of sustaining the local nursing workforce' and 'Challenges of educational preparation for local nurses'. The participants agreed that Omanization benefited national development, social stability and ensuring local workforce. The challenges faced were cultural and work life balance, preparation of nurses and pace of replacement. CONCLUSION: The participants were concerned that the pace of replacement could leave behind a marked experience gap. A slow-phased approach to Omanization of the nursing workforce was recommended by the participants. LIMITATIONS: Results obtained from this study reflect the perceptions and voices of student nurses and registered nurses only from the Institute of Nursing and Oman Ministry of Health. IMPLICATIONS FOR NURSING EDUCATION AND POLICY: A policy of this magnitude requires gradual establishment. The upgrading of the nursing education to degree level, continuous professional development, mentoring and role modeling of expert nurses should be established to prepare local nurses for the localization of the nursing workforce.

Sickle cell anemia and α-thalassemia: a modulating factor in homozygous HbS/S patients in Oman.

We report the general phenotype severity and the hematological presentation in a cohort of 125 sickle cell anemia (SCA) patients with identical homozygous HbS/S genotype and categorized by identical ß(S) haplotype, both with and without alpha thalassemia. No clear general phenotype correlation was found when patients were compared regardless of the haplotype but overall, patients with homozygous alpha thalassemia (α-/α-) had the highest Hb, HCT, RBC and the lowest MCV, MCH and MCHC levels. When patients with identical haplotype were compared, the mildest hematological and clinical conditions were observed in patients of the Asian/Asian haplotype, also known as Arab-Indian haplotype, and carriers of α-thalassemia, suggesting an additional ameliorating effect of alpha thalassemia. In conclusion, our results show that alpha thalassemia improves the hematological conditions but amelioration of the general disease severity is only noticed when compared in cohorts of the same haplotype.

Profile of acute poisoning cases presenting to health centres and hospitals in Oman.

A simple pro forma was used for a retrospective study of poisoning cases at 45 health institutions in Oman during January-December 2000. No deaths were recorded among 2009 cases of acute poisoning. A quarter of all cases (55.8% of paediatric cases) were children aged 1-4 years. The largest category (59.5%) was animal bites and stings: 25.4% undiagnosed, 19.7% scorpion stings, 7.6% bee, spider or wasp stings and 6.8% snake bites. Next highest (38.5%) was ingestion of substances: 18.2% pharmaceuticals, 8.2% food and 4.7% household products. Most drug-related cases were due to paracetamol. Suicide attempts were recorded for 6.0%. Collection of poisoning data through a central registry system is needed for the implementation and future assessment of prevention programmes.
