ABSTRACT
Myopericytoma is a rare tumor that arises from perivascular myoid cells. Intravascular myopericytoma is an exceptionally rare subtype with a small number of cases reported. Here, we describe the case of a 31-year-old woman who presented with a lump on the dorsum of the right foot for nine months. Imaging indicated that the lesion is in close proximity to the dorsalis pedis vessels. Following surgical excision, the histological analysis revealed a benign neoplasm arising within a vein wall with features of vascular and pericytic differentiation. When using immunohistochemistry, the blood vessels were highlighted by the cluster of differentiation (CD) 31 and smooth muscle actin (SMA) with negative staining for pancytokeratins. These features led to the diagnosis of intravascular myopericytoma.
ABSTRACT
A closed fifth metacarpal neck fracture is a frequently encountered upper limb fracture that occurs when the bone breaks right below the little finger's knuckle. At the moment, there is no agreement on the best way to treat these fractures. This research seeks to look at the efficacy of buddy taping versus reduction and casting for non-operative management of uncomplicated closed fifth metacarpal neck fractures. A systematic review of PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed Central (PMC), and the Cochrane Library databases was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to find relevant studies about buddy taping versus reduction and casting for non-operative management. Disabilities of the arm, shoulder, and hand (DASH) score; satisfaction score; visual analog scale (VAS); range of motion (ROM); strength; and other outcomes were reported in this study. We used Review Manager 5.4 (The Cochrane Collaboration, London, UK) for the meta-analysis. Seven trials with a total of 454 patients were considered in the review and four in the quantitative analysis. All the included studies were randomized controlled trials (RCTs). Our study concluded that buddy taping was effective for improving pain, range of motion, and strength. The DASH score and satisfaction score didn't show any significant difference. Thus, we recommend the use of buddy taping rather than plaster and immobilization for the management of uncomplicated closed fifth metacarpal neck fractures.
ABSTRACT
Sickle Cell Disease (SCD) is a disease that affects many around the world and often accounts for frequent hospital admissions every year, secondary to uncontrolled pain. Marijuana is increasingly being used for its medicinal ability to treat pain in chronic medical conditions. Therefore, it is imperative to determine how effective it would be in providing pain relief to patients with SCD. We systematically screened five databases for relevant data: PubMed, Medline, PubMed Central (PMC), Cochrane Library, and Google Scholar. The inclusion and exclusion criteria were implemented. A quality appraisal was then done using the Cochrane Bias assessment for randomized controlled trials (RCTs), Newcastle-Ottawa tool for observational studies, and Scale for the Assessment of Narrative Review Articles (SANRA) checklist for traditional review articles. From seven articles, information was gathered; one systematic review, one RCT, two surveys, one cross-sectional study, one retrospective study, and one questionnaire-based study. Our review concluded that based on the literature assessed, marijuana use in SCD patients either worsened their painful crises or offered little to no help compared to opioids or hydroxyurea usage. There were limited RCTs published in addition to papers investigating the long-term effects of marijuana use in SCD. We hope that further data is gathered in these areas to sufficiently address whether cannabis use is efficacious for pain relief in patients with SCD.
ABSTRACT
It has been recommended that adults sleep a minimum of seven hours of sleep every night to maintain holistic health and well-being. A considerable fraction of the adult population suffers from sleep deprivation and related disorders. The stress of modern-day living may be the cause of this curtailment of sleep duration. The primary purpose of this study was to investigate the effects of reduced sleep on the development of insulin resistance and explore the possible mechanisms linking the two. We utilized databases like such as PubMed, PubMed Central (PMC), and Medical Literature Analysis and Retrieval System Online (MEDLINE) to systematically screen papers using keywords and Medical Subject Heading (MeSH) terms. A few articles were also retrieved from Cochrane Library. We applied inclusion/exclusion criteria after screening papers via title and abstracts. A quality appraisal check was doneperformed, and ten 10 related studies were strictly reviewed. Short sleep duration was significantly associated with insulin resistance. Inflammatory markers such as C-reactive protein (CRP) and serum amyloid A (SAA), biomarkers such as glucagon-like peptide-1 (GLP-1), and circadian misalignment may play a significant role in the pathogenesis of this association. To prevent metabolic complications such as type- 2 diabetes, adequate sleep (more than seven hours per night) is required in the adult population. The causal relationship between sleep deprivation and insulin resistance is multifactorial, and further studies are warranted to understand these mechanisms better.
ABSTRACT
Chronic lymphocytic leukaemia (CLL) is one of the most common haematological malignancies worldwide, with an increasing prevalence in the elderly population. Obinutuzumab is a type II anti-CD20 monoclonal antibody which showed superiority over rituximab in combination chemotherapy with chlorambucil for the treatment of CLL in the CLL11 trial (NCT01010061) and is becoming part of standard first line treatment for CLL in the elderly based on its potent efficacy and benign safety profile. We report the case of a chemotherapy naive patient who develop tumour lysis syndrome despite appropriate prophylaxis, and had partial remission of her disease after receiving only the initial test dose of obinutuzumab. LEARNING POINTS: Chemotherapy-induced tumour lysis syndrome is a serious complication that can occur after even a small dose of chemotherapy.Chronic lymphocytic leukaemia patients with strongly positive CD20 cells can be more sensitive to obinutuzumab chemotherapy.
ABSTRACT
BACKGROUND: The management of major omphalocoele and large incisional hernias is a common problem and constitutes a great challenge for paediatric surgeons. In most cases, the abdominal cavity is so small and does not allow immediate reduction. Prosthetic materials are becoming increasingly popular for such repair, but direct contact between the bowel and these synthetic materials carries the risk of adhesions and intestinal obstruction. The relatively new PROCEED mesh with absorbable layer in contact with the bowel and another polypropylene non-absorbable layer against the abdominal wall may not produce such adhesions. The aim of this study is to evaluate the feasibility and outcome of this relatively new prosthetic mesh for repair of ventral hernia . PATIENTS AND METHODS: Between June 2009 and December 2012, a pilot study was conducted on 22 cases with large ventral hernias subjected to open surgical repair using PROCEED mesh. The inclusion criterion was cases with large ventral hernias (>4 cm). The evaluating parameters were all the early and late postoperative complications. RESULTS: The defect size ranged from 5 to 12 cm. The early postoperative complication (≤1 month) was seroma discharged from the wound in four cases, while the late complications were recurrent herniation and stitch sinus that occurred in three cases. No manifestations of intestinal obstruction, enterocutaneous fistula or mortality were encountered in any of the 22 cases. CONCLUSION: The use of PROCEED composite mesh in ventral hernias is feasible and has minimal complication rates.
