Bilateral dilation of the urinary tract due to iliopsoas pyomyositis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pyomyositis is an acute bacterial infection of the skeletal muscles that arises from hematogenous spread and is caused predominantly by Gram-positive cocci.</p> <p>Case presentation</p> <p>We report a case of iliopsoas pyomyositis in a 25-year-old Greek Caucasian woman with a history of intravenous drug use. Her condition was complicated by bilateral dilation of the ureters and renal calyces as a result of mechanical pressure from inflammation and edema of the involved muscle. The patient did not present aggravation of renal function and was treated successfully solely with intravenous antibiotics, without surgical intervention. This is the first case report describing iliopsoas pyomyositis with reversible bilateral dilation of the urinary tract that was treated successfully with intravenous antibiotics, without surgical intervention.</p> <p>Conclusion</p> <p>We present the first described case of iliopsoas pyomyositis with reversible bilateral hydroureteronephrosis that was treated successfully with intravenous antibiotics, without the necessity of surgical intervention. To our knowledge, this is the first report of its kind in the literature regarding an unexpected event in the course of treating a patient with iliopsoas pyomyositis, and it should be of particular interest to different clinical medical specialties such as internal medicine, infectious disease and urology.</p

TB infection prevention and control experiences of South African nurses - a phenomenological study

<p>Abstract</p> <p>Background</p> <p>The tuberculosis (TB) epidemic in South Africa is characterised by one of the highest levels of TB/HIV co-infection and growing multidrug-resistant TB worldwide. Hospitals play a central role in the management of TB. We investigated nurses' experiences of factors influencing TB infection prevention and control (IPC) practices to identify risks associated with potential nosocomial transmission.</p> <p>Methods</p> <p>The qualitative study employed a phenomenological approach, using semi-structured interviews with a quota sample of 20 nurses in a large tertiary academic hospital in Cape Town, South Africa. The data was subjected to thematic analysis.</p> <p>Results</p> <p>Nurses expressed concerns about the possible risk of TB transmission to both patients and staff. Factors influencing TB-IPC, and increasing the potential risk of nosocomial transmission, emerged in interconnected overarching themes. Influences related to the healthcare system included suboptimal IPC provision such as the lack of isolation facilities and personal protective equipment, and the lack of a TB-IPC policy. Further influences included inadequate TB training for staff and patients, communication barriers owing to cultural and linguistic differences between staff and patients, the excessive workload of nurses, and a sense of duty of care. Influences related to wider contextual conditions included TB concerns and stigma, and the role of traditional healers. Influences related to patient behaviour included late uptake of hospital care owing to poverty and the use of traditional medicine, and poor adherence to IPC measures by patients, family members and carers.</p> <p>Conclusions</p> <p>Several interconnected influences related to the healthcare system, wider contextual conditions and patient behavior could increase the potential risk of nosocomial TB transmission at hospital level. There is an urgent need for the implementation and evaluation of a comprehensive contextually appropriate TB IPC policy with the setting and auditing of standards for IPC provision and practice, adequate TB training for both staff and patients, and the establishment of a cross-cultural communication strategy, including rapid access to interpreters.</p

Guideline for the treatment of myelodysplastic syndromes (MDS) in South Africa

The original publication is available at http://www.samj.org.zaIntroduction. Myelodysplastic syndromes (MDS) encompass a heterogeneous group of clonal haematopoietic disorders characterised by chronic and progressive cytopenias resulting from ineffective haematopoiesis. Treatment is complicated by differences in disease mechanisms in different subgroups, variable clinical phenotypes and risk of progression to acute myeloid leukaemia. Rationale. Changes in disease classification, prognostic scoring systems, the availability of novel treatment options and the absence of South African guidelines for the diagnosis and management of these complex disorders underpinned the need for the development of these recommendations. Methods. These recommendations are based on the opinion of a number of experts in the field from the laboratory as well as clinical settings and came from both the private and institutional academic environments. The most recent literature as well as available guidelines from other countries were discussed and debated at a number of different meetings held over a 2-year period. Results. A comprehensive set of recommendations was developed focusing on risk stratification, supportive management and specific treatment. Novel agents and their indications are discussed and recommendations are made based on best available evidence and taking into account the availability of treatments in South Africa. Conclusion. Correct diagnosis, risk stratification and appropriate therapeutic choices are the cornerstones of success in the management of patients with MDS.Publishers' Versio

Identifying contextual determinants of problems in tuberculosis care provision in South Africa: a theory-generating case study

Background: Despite progress towards End TB Strategy targets for reducing tuberculosis (TB) incidence and deaths by 2035, South Africa remains among the top ten high-burden tuberculosis countries globally. A large challenge lies in how policies to improve detection, diagnosis and treatment completion interact with social and structural drivers of TB. Detailed understanding and theoretical development of the contextual determinants of problems in TB care is required for developing effective interventions. This article reports findings from the pre-implementation phase of a study of TB care in South Africa, contributing to HeAlth System StrEngThening in Sub-Saharan Africa (ASSET)—a five-year research programme developing and evaluating health system strengthening interventions in sub-Saharan Africa. The study aimed to develop hypothetical propositions regarding contextual determinants of problems in TB care to inform intervention development to reduce TB deaths and incidence whilst ensuring the delivery of quality integrated, person-centred care. Methods Theory-building case study design using the Context and Implementation of Complex Interventions (CICI) framework to identify contextual determinants of problems in TB care. Between February and November 2019, we used mixed methods in six public-sector primary healthcare facilities and one public-sector hospital serving impoverished urban and rural communities in the Amajuba District of KwaZulu-Natal Province, South Africa. Qualitative data included stakeholder interviews, observations and documentary analysis. Quantitative data included routine data on sputum testing and TB deaths. Data were inductively analysed and mapped onto the seven CICI contextual domains. Results: Delayed diagnosis was caused by interactions between fragmented healthcare provision; limited resources; verticalised care; poor TB screening, sputum collection and record-keeping. One nurse responsible for TB care, with limited integration of TB with other conditions, and policy focused on treatment adherence contributed to staff stress and limited consideration of patients’ psychosocial needs. Patients were lost to follow up due to discontinuity of information, poverty, employment restrictions and limited support for treatment side-effects. Infection control measures appeared to be compromised by efforts to integrate care. Conclusions: Delayed diagnosis, limited psychosocial support for patients and staff, patients lost to follow-up and inadequate infection control are caused by an interaction between multiple interacting contextual determinants. TB policy needs to resolve tensions between treating TB as epidemic and individually-experienced social problem, supporting interventions which strengthen case detection, infection control and treatment, and also promote person-centred support for healthcare professionals and patients

AIDS defining lymphomas in the era of highly active antiretroviral therapy (HAART) - An African perspective

The intermediate to high grade B-cell non-Hodgkin lymphomas are now one of three malignant AIDS defining conditions. The others being Kaposi's sarcoma and cervical carcinoma. While co-infection with oncogenic agents including the human herpes 8 or Epstein-Barr virus offer targets in preventive treatment strategies for these AIDS defining lymphomas (ADL), administration of highly active antiretroviral therapy leading to immune reconstitution permits use of standard or even high-dose cytotoxic drug regimens with curative intent. It is not certain whether this should be done concomitantly or sequentially. Additional benefit may derive from infusional or high-dose chemotherapy regimens depending on the histological subtype while use of monoclonal antibodies such as rituximab or immunohaematopoietic stem cell transplantation needs to be further evaluated within controlled studies. Socio-economic considerations have an impact especially in resource limited settings while availability of tools for appropriate geno-phenotypic diagnosis and immunological monitoring such as the CD4 cell count will play an important role in the risk stratification as well as disease management. While it is generally accepted that the impact of HAART has an overall benefit both in incidence and treatment outcome in ADL, the expanded access to HAART programs are falling short of all targets in Africa. Accordingly focus is given to some of these controversies, including epidemiology, pathogenesis, clinical features, therapeutic options and ethical considerations. © 2007 Elsevier Ltd.

Use of novel proteosome inhibitors as a therapeutic strategy in lymphomas current experience and emerging concepts

Precedent from preclinical experiments coupled with two pivotal phase 2 studies in myeloma has focused attention on a potential role for ubiquitin-proteasome pathway in modulating a number of events that occur commonly in the neoplastic process involving proteins in the regulation of cells cycling, growth and differentiation. This influence is vested in the proteasomes which are large complexes of proteolytic enzymes responsible for degradation of many of these intracellular messengers. Logically interest has centred on molecules having the capacity to influence, by degradation, such molecules and although a number of agents are in development bortezomib is the only one currently in clinical use. Velcade, formerly PS-341, is a novel dipeptide boronic acid capable of reversibly inhibiting the 26S proteasome through a range of activities. The latter are anti-proliferative and proapoptotic with the latter blocking nuclear transcription via NF-κ B in addition to down regulating adhesion and inhibiting angiogenesis. Additional changes are mediated in protein folding within the endoplasmic reticulum and contribute to cell death. These concepts are given focus by considering their introduction into treatment of lymphoreticular malignancy. © 2007.Articl
