We present a case of a case of a man in his 70s on multiple medications (including treatment of ischemic heart disease and diabetes who developed significant rhabdomyolysis, complicated by acute kidney injury (AKI) and encephalopathy, while using a compounded medication for weight loss. The patient was admitted to the intensive care unit and progressed favourably after haemodialysis and supportive care. Information regarding the ingestion of weight-loss drugs was unknown at the time of admission and was only discovered after resolution of encephalopathy, raising the possibility of toxin-associated rhabdomyolysis. This case emphasises the need for a thorough clinical history and scrutiny of the safety of weight-loss prescriptions, including preparations that comprise a combination of drugs and supplements that may adversely interact with chronic medications, especially in polymedicated patients.

Septic arthritis (SA) is a serious infection of the joint which can lead to irreversible destruction of the joint.We report a case of right hip SA with septic pulmonary embolism following a complicated dental extraction in a woman in her early 40s with sickle cell trait (SCT).The patient presented with severe right thigh pain and left jaw pain.Initial workup revealed raised C reactive protein and positive blood cultures. Right hip joint SA was confirmed following intraoperative joint aspiration. The patient had right hip debridement with long-term intravenous antibiotics.The incidence of SA in adults with sickle cell disease is low: 0.3% in a study in France and Brazil and 10.3% incidence of haematogenous osteoarticular infection in children with SCT in West Africa.

Paradoxical masseteric bulging refers to an unexpected occurrence of masseter muscle bulging or protrusion following the administration of botulinum toxin injections, contrary to the anticipated muscle weakening effect. It may occur secondary to toxin failing to diffuse through the entire masseter muscle due to the presence of an inferior tendon structure within the superficial masseter that divides it into a superficial and deep belly. We report a clinical case of paradoxical masseteric bulging in a female in her late 40s who developed this adverse effect within a week of her masseter botulinum neurotoxin type A injections. We also describe the masseter two-site injection technique for the management of this complication.

PYROXD1-associated myopathy is a rare genetic form of limb-girdle muscular dystrophy (LGMD) with only 23 previous cases having been reported in the literature. The exact role of PYROXD1 in the pathophysiology of LGMD remains unclear. We describe two brothers who presented to the neuromuscular clinic with progressive weakness of their upper and lower limbs over the preceding decades. Our case highlights how recent advancements in genetic sequencing have revolutionised the diagnostic classification process for LGMD and provided opportunities to establish diagnoses for previously unclassified myopathies. We also illustrate how the increased adoption of muscle MRI to identify disease and target muscle biopsy can provide better quality and more informative samples for classification. Finally, our report details the clinical and histopathological findings found in both cases adding valuable data to the currently limited information published on PYROXD1-associated myopathy.

We present the case of an elderly man with a small-joint polyarthritis, accompanied by pitting oedema, involving hands and feet, raising clinical suspicion of remitting seronegative symmetrical synovitis with pitting oedema (RS3PE). Treatment with corticosteroids was initiated with significant improvement, but unacceptable iatrogeny ensued, and tapering was not possible without disease flare-up. A trial of tocilizumab allowed disease activity control, slow weaning of corticosteroids and, ultimately, its suspension. RS3PE is a rare rheumatological entity, initially thought to be a variant of rheumatoid arthritis (RA), with shared traits with polymyalgia rheumatica (PMR), and other seronegative spondyloarthropathies, thereby implying a shared pathophysiological background. Elevated levels of interleukin 6 (IL-6) are found in patients with RA, have shown to mirror disease activity in PMR and have also been described in the serum and synovial fluid of patients with RS3PE. Tocilizumab, an anti-IL-6 receptor antibody, shows auspicious results in several other rare rheumatic diseases other than RA.

Idiopathic inflammatory myopathies are neuromuscular disorders characterised by muscle weakness and histologically inflammation within the muscle. Dermatomyositis and polymyositis are highly associated with a wide range of cancers, especially in antitranscriptional intermediary factor-1 (TIF1)-gamma-positive myositis. We present a case of paraneoplastic dermatomyositis in a patient with a medical history of a FIGO stage 1B1 cervical squamous cell carcinoma. Anti-TIF1-gamma autoantibodies were detected by myositis lineblot analysis and a PET-CT scan revealed an abnormality positioned at the right ovary. She underwent laparoscopic exploration and pathological analysis of the PET-positive abnormality showed a lymphogenic metastasis of a squamous cell carcinoma, competitive with cervical carcinoma recurrence. She started chemoradiation as curative oncological treatment. The dermatomyositis was successfully treated with high-dose corticosteroids. Physicians should be aware of the association between myositis and the increased risk of malignancies.

Myofibrillar myopathies (MFMs) are a group of rare genetic disorders that affect the function of skeletal, cardiac and smooth muscle.MFM exhibits a considerable degree of clinical heterogeneity. In numerous instances of MFM, muscle weakness is the predominant manifestation. Certain MFM subtypes are distinguished by respiratory and cardiac impairment.There is little information available about anaesthetic management in MFM, and even less is known about obstetric anaesthesia.A successful case of a patient with MFM undergoing a caesarean section under combined neuraxial anaesthesia is reported. The patient experienced no complications, and functional recovery was swift.

A young male presented with intermittent high-grade fever, asymmetric polyarthritis and erythematous, tender nodules over left shin for 2 months duration. He had a history of alcohol dependence with multiple episodes of acute pancreatitis. With polyarthritis progressing relentlessly, unresponsive to non-steroidal anti-inflammatory drugs and steroids, a provisional diagnosis of sarcoidosis was considered. Indeed, he was treated with azathioprine and rituximab with no effect. Biopsy of the skin nodule revealed subcutaneous fat necrosis, foam cells, deposition of eosinophilic amorphous material and calcification. Synovial fluid aspiration from the arthritic knee obtained purulent but surprisingly culture-negative material, rich in triglycerides. Abdominal CT confirmed chronic pancreatitis. Final diagnosis of pancreatitis, panniculitis and polyarthritis (PPP) syndrome was made. He underwent surgical pancreatic ductal drainage leading to complete remission of symptoms. PPP syndrome triad occurs due to leakage of pancreatic enzymes into systemic circulation and subsequent fat necrosis. Surgical drainage of pancreatic duct is often curative.
