BACKGROUND: Puerperal sepsis is a life-threatening condition caused by infection that can rapidly progress to multisystem infection and toxin-mediated shock. Symmetrical peripheral gangrene is defined as symmetrical distal ischemic damage in two or more sites in the absence of major vascular occlusive disease. The syndrome is devastating and rare. In this study, we introduce a case of puerperal septicemia complicated by symmetrical peripheral gangrene.
METHODS: A 23-year-old woman delivered a live female infant vaginally after cervical balloon dilatation at 39 weeks of gestation. Persistent hyperthermia developed on the first postpartum day. After experiencing ventricular fibrillation, acute liver failure, and acute pulmonary edema, she developed blackened extremities on the 5th postpartum day.
METHODS: Puerperal septicemia complicated by symmetrical peripheral gangrene.
METHODS: Upon transfer to our hospital, the patient was enrolled in the intensive care unit and underwent anti-infective and amputation surgery.
RESULTS: After the surgery, the patient recovered well and was successfully discharged from the hospital.
CONCLUSIONS: Early detection and timely treatment is the best way to reduce the mortality and sequelae of puerperal sepsis. Physicians should be alert to the possibility of comorbid symmetrical peripheral gangrene when sepsis patients present with hepatic impairment.

Persistent sciatic artery is a rare anatomic variation due to the lack of regression during fetal development, associated sometimes with abnormalities of the iliofemoral arterial axis and predisposing the patients to aneurysm formation and thromboembolism, which can compromise the limb. In our department, we assisted a 59-year-old male with an acute limb ischemia as result of an incidental finding of a thrombosed persistent sciatic artery aneurysm.

Aplasia cutis congenita (ACC) is a rare congenital disorder characterised by localised or widespread absence of skin mainly affecting the scalp. Bilateral involvement of both the upper and lower extremities is uncommon. This is a case report of a rare congenital disorder. The patient was a 26-hour-old male baby admitted with extensive absence of skin on the lower and upper extremities. He was co-managed conservatively with the plastic surgical team for ACC group VII. The lesions were healing satisfactorily until 12 days into the admission when the parents signed against medical advice despite counselling. ACC with involvement of both upper and lower extremities is a rare presentation that responds to conservative treatment. The report emphasises the need for a legal framework for physicians to override the decision of the caregiver not in the best interest of a child.

A 74-year-old woman taking dulvalumab for lung adenocarcinoma developed muscle tonicity in the extremities and trunk. Painful paroxysmal muscle spasms with profuse sweating were frequently observed, and surface electromyography showed simultaneous contraction of the active and antagonist muscles. Blood tests were strongly positive for anti-amphiphysin antibodies, and stiff-person syndrome (SPS) was diagnosed. Intravenous immunoglobulin therapy and clonazepam were initiated, and the paroxysmal painful muscle spasms disappeared. As the primary tumor was under control, and the onset occurred approximately six weeks after the resumption of immune checkpoint inhibitors, we considered SPS to be an immune-related adverse event. Although extremely rare, it should be considered a neuromuscular disease that can occur in association with immune checkpoint inhibitors.

BACKGROUND: During the wars in Afghanistan and Iraq most injuries to service members involved the musculoskeletal system. These wounds often occurred around joints, and in some cases result in traumatic arthrotomy-a diagnosis that is not always clear, especially when there is no concomitant articular fracture. The aim of the present study is to evaluate the diagnosis and treatment of peri-articular blast injuries without fracture.
METHODS: The study cohort included 12 consecutive patients (12 involved extremities) who sustained peri-articular blast wounds of the extremities without fractures. The diagnosis of penetrating articular injury was based on clinical examination, radiographic findings, or aspiration. A peri-articular wound was defined as any wound, or radio-opaque blast fragment, within 5 cm of a joint. The New Injury Severity Score (NISS) was calculated for each patient. Four patients had upper, and 8 patients had lower extremity injuries. Nine of 12 patients had joint capsular penetration and underwent joint irrigation and debridement.
RESULTS: Two patients had retained intra-articular metal fragments. One patient had soft tissue blast wounds within 5 cm of a joint but did not have joint capsule penetration. There were no significant differences (p = 0.23) between the distribution of wounds to upper versus lower extremities. However, there were a significantly greater number of blast injuries attributed to Improvised Explosive Devices (IEDs) than from other blast mechanisms (p = 0.01).
CONCLUSIONS: Extremity blast injuries in the vicinity of joints involving only soft tissues present a unique challenge in surgical management. A high index of suspicion should be maintained for joint capsular penetration so that intra-articular injuries may be appropriately treated.

Necrotising fasciitis (NF) is a life-threatening bacterial infection characterised by rapid tissue destruction, which can have severe consequences if not recognised early and treated promptly. It is most commonly caused by group A streptococcus entering the body through breaks in the skin. This case report describes a patient who presented with systemic signs of infection, including right axillary pain, following a recent intramuscular injection. Clinical examination and radiological findings were consistent with NF, and surgical exploration confirmed the diagnosis of thoracic NF. The patient underwent extensive surgical debridement, intensive care management and subsequent reconstructive surgery. This report highlights the importance of early recognition of NF and that this condition is not limited to the limbs but may also affect the torso. It employs consideration of all portals of potential bacterial entry that may prompt a differential of NF through thorough history taking. This case encourages healthcare professionals to maintain awareness of skin infections as a potential though rare complication of procedures such as injections hence the continued value of aseptic techniques to minimise risk. Finally, it emphasises that prompt diagnosis, appropriate antibiotic therapy and immediate surgical intervention remain crucial in managing NF and improving patient outcomes.

We explored the first evidence of a single-session neuromuscular biofeedback effect on motor unit properties, neuromuscular activation, and the Achilles tendon (AT) length 12 days after undergoing AT surgical repair. We hypothesized that immediate neuromuscular biofeedback enhances motor unit properties and activation without causing AT lengthening. After 12 days AT surgical repair, Medial Gastrocnemius (MG) motor unit decomposition was performed on a 58-year-old male before and after a neuromuscular biofeedback intervention (surface electromyography (sEMG) and ultrasonography), involving unressited plantar flexion. The analysis included motor unit population properties, sEMG amplitude, force paradigm, and AT length. There were increased MG motor unit recruitment, peak and average firing rate, coefficient of variation, and sEMG amplitude, and decreased recruitment and derecruitment threshold in the repaired AT limb. The non-injured limb increased the motor unit recruitment, and decreased the coefficient of variation, peak and average firing rate, inter-pulse interval, derecruitment threshold and sEMG amplitude. The AT length experienced -0.4 and 0.3 cm changes in the repaired AT and non-injured limb, respectively. This single-session neuromuscular biofeedback 12 days after AT surgery shows evidence of enhanced motor unit properties and activation without signs of AT lengthening when unresisted plantar flexion is performed in the repaired AT limb.

Extramammary Paget disease is a rare dermatological condition resembling Paget disease that occurs most commonly in the anogenital area and axilla. We present the case of an elderly male who had come with complaints of an itchy, erythematous and raised lesion in the perianal region for 3 months that did not respond to antifungals. A biopsy was taken from the lesion site and the diagnosis was confirmed by histopathological examination. It is important to be aware of conditions like extramammary Paget disease when an elderly individual presents with a non-specific pruritic lesion in the perianal area that is non-responsive to treatment; the diagnosis of which can be made only by doing a biopsy from the concerned site. This highlights the importance of histopathological examination in such ambiguous cases.

Major extremity fractures are serious limb injuries often including notable soft-tissue injury with possible injuries to the head, chest, or abdomen. High-energy traumatic fractures carry a high risk of surgical site infections even with use of systemic antibiotics and techniques in risk reduction. The American Academy of Orthopaedic Surgeons released a clinical practice guideline in 2023 based on current literature on the prevention of surgical site infections after major extremity trauma. The case presented in this article is an example to demonstrate the clinical application of these guidelines.
