Septic arthritis of the knee and necrotizing fasciitis in a young immunocompetent adult: a case report / Hayatul Najaa Miptah … [et al.]

Septic arthritis is uncommon in immunocompetent young adults. It typically presents in individuals with underlying risk factors. Isolation of Group A Streptococcus (GAS) as the causative agent of septic arthritis is usually associated with autoimmune diseases, chronic skin infections or trauma. Here we report a case of a young lady who is immunocompetent without any prior history of trauma, who presented with an abrupt onset of left knee pain and swelling to the emergency department. An initial diagnosis of acute gout was made and she was treated with non-steroidal anti-inflammatory drug (NSAID). She presented again two days later to a primary care clinic with worsening knee pain and severe left calf pain. A clinical diagnosis of septic arthritis was suspected and the patient was urgently referred to the Orthopaedic team. Synovial fluid from the knee joint aspiration showed growth of GAS. A diagnosis of necrotizing fasciitis was also made as the culture taken from the left calf during incision and drainage (I&D) procedure showed a mixed growth. She eventually underwent surgical debridement twice, together with the administration of several courses of intravenous antibiotics leading to her full recovery after 45 days. This case demonstrates the challenge in making a prompt diagnosis of septic arthritis and probable Type II necrotizing fasciitis in an immunocompetent adult without underlying risk factors. Any delay in diagnosis and treatment would have increased the risk of damage to her knee joint and this may be fatal even in a previously healthy young adult

Adult ileocolic intussusception secondary to ileocaecal valve polyp

Intussusception is relatively common in children, but it is a rare cause of abdominal pain and intestinal obstruction in adults. The aetiology, clinical presentation and management of this condition differs in adults and children. Preoperative clinical diagnosis is usually difficult due to the non-specific and intermittent nature of the symptoms. Ultrasound and computed tomography can be helpful in establishing the diagnosis. We present a case of adult ileocolic intussusception with classical radiological signs and operative findings. In adults the diagnosis of intussusception should be considered in a case of intermittent abdominal pain, especially with clinical signs of intermittent bowel obstruction

A systematic review and meta-analysis of the prevalence of dyslipidaemia among adults in Malaysia

Abstract Dyslipidaemia is an established cardiovascular risk factor. This study aimed to determine the pooled prevalence of dyslipidaemia in Malaysian adults. A systematic review and meta-analysis of all cross-sectional, longitudinal observational studies which reported the prevalence of elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), and reduced high-density lipoprotein cholesterol (HDL-c) in adults 18 years old and older, was conducted. A comprehensive search of PubMed and Cochrane Central Register of Controlled Trials (which included Medline, EMBASE and major trial registers) from inception to October 18, 2022, was performed. Risk-of-bias was evaluated using the Johanna-Briggs Institute Prevalence Critical Appraisal Tool, while certainty of evidence was assessed using an adapted version of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. Random-effects meta-analyses were performed using MetaXL. This report follows the PRISMA reporting guidelines. The protocol was registered with PROSPERO (CRD42020200281). 26 556 studies were retrieved and 7 941 were shortlisted initially. From this, 70 Malaysian studies plus two studies from citation searching were shortlisted; 46 were excluded, and 26 were included in the review (n = 50 001). The pooled prevalence of elevated TC (≥ 5.2 mmol/L), elevated LDL-c (≥ 2.6 mmol/L), elevated TG (≥ 1.7 mmol/L), and low HDL-c (< 1.0 mmol/L in men and < 1.3 mmol/L in women) were 52% (95% CI 32–71%, I2 = 100%), 73% (95% CI 50–92%, I2 = 100%), 36% (95% CI 32–40%, I2 = 96%), and 40% (95% CI 25–55%, I2 = 99%), respectively. This review found that the prevalence of all dyslipidaemia subtypes is high in Malaysian adults. Ongoing efforts to reduce cardiovascular diseases in Malaysia should integrate effective detection and treatment of dyslipidaemia
