Using a flap in a large wound with a very small area of exposed vital structures may be an excessive intrusion and cause unnecessary donor site morbidity. Dermal matrix (DuraGen) was applied onto critical areas where bone or tendons were exposed and a split skin graft was placed thereon. All patients had satisfactory wound closure without the need for a flap. DuraGen appears to be a safe, single-stage alternative, to a flap for the healing of complex wounds.
Hydroxyuria is a common medication for treating blood system diseases, but ulcers in the lower limbs caused by this medication are often rare and not often suspected. We reported an elderly patient with lower limb ulcers caused by hydroxyurea treatment for primary thrombocytosis. When hydroxide is used, close observation of skin lesions and prompt handling of any skin disruption should prevent ulcers.
Recent data have demonstrated the changing epidemiology of primary pyomyositis worldwide. Our hospital-based retrospective study investigated the clinical and microbiological spectrum of primary pyomyositis between 2013 and 2021 in PGIMER (Chandigarh), India. Over a quarter had predisposing conditions, mainly diabetes mellitus and immunosuppressive therapy. Fever, muscle pain, local swelling and breathlessness were the usual presentations, with quadriceps, iliopsoas and gluteal muscles commonly affected. Staphylococcus aureus was the predominant cause, with c.50% methicillin-resistant strains. Almost two-thirds presented with metastatic infection (stage 3 pyomyositis), frequently with septic lung emboli. Patients with methicillin-sensitive and resistant Staphylococcus aureus had a similar incidence of metastatic infection. In-hospital mortality was c.10% and was strongly associated with a high international normalised ratio. Primary pyomyositis remains a significant problem, with a dramatic increase in community-associated methicillin-resistant Staphylococcus aureus.
Acute kidney injury in the Tropics is strikingly different from that in developed countries in terms of aetiology and presentation. Moreover, there are radical differences between the developed world and the economically poorer regions within the tropics. Infections are the number one cause leading to significant mortality. This article reviews the most common causes of acute kidney injury in the Tropics and describes its management briefly.
