Fournier's gangrene (FG) is a synergistic polymicrobial gangrenous infection of the perineum, scrotum and penis which is characterised by obliterative endarteritis of the subcutaneous arteries, resulting in gangrene of the subcutaneous tissue and the overlying skin. FG affects all ages and both genders, with a male preponderance. It is a rare but life-threatening disease, and despite therapeutic advances in recent years, the mortality rate is 3%-67%, with an incidence of 1:7500-1:750,000. ⋯ Treatment of FG is based on a multimodal approach which includes intensive fluid resuscitation to stabilise the patient and correction of electrolyte imbalance, if any. This is followed by extensive debridements and resections in order to remove all necrotic and infected tissue, wide spectrum antibiotics and reconstructive surgery, whenever required. However, despite all the advances in treatment today, FG remains a surgical emergency, hence, early recognition with aggressive haemodynamic stabilisation, parenteral broad spectrum antibiotics and urgent surgical debridement are the mainstay of treatment.

ReviewThe surgical management of Spitz naevi and atypical spitzoid neoplasms: A review of the literature.
Melanocytic lesions with spitzoid differentiation represent a difficult management paradigm. Spitzoid lesions form a spectrum of distinct entities encompassing Spitz naevi, atypical Spitz naevi and spitzoid melanoma which range from benign to malignant. ⋯ We review the literature in terms of the newer histological tools available to more explicitly classify these lesions which may have an impact on the clinical care that these patients receive. The article also examines the controversy which surrounds the role of sentinel lymph node biopsy (SLNB) and completion lymph node dissection in the management of melanocytic proliferations with Spitz differentiation.

Despite the medical hazards of obesity, recent reports examining body mass index (BMI) show an inverse relationship with morbidity and mortality in the surgical patient. This phenomenon is known as the 'obesity paradox'. The aim of this review is to summarize both the literature concerned with the obesity paradox in the surgical setting, as well as the theories explaining its causation. ⋯ Patients at the extremes of BMI, both the underweight and the morbid obese, seem to have the highest postoperative morbidity and mortality hazard, which even persists at long-term. The cause of the obesity paradox is probably multi-factorial. This offers potential for future research in order to improve outcomes for persons on both sides of the 'optimum BMI'.

Thyroid incidentalomas are commonly found on cross-sectional imaging of the neck and they are equally likely to be malignant as palpable thyroid nodules. Guidelines on their management are conflicting. Ultrasonography cannot accurately differentiate benign from malignant thyroid nodules and fine needle aspiration biopsy should be used selectively to avoid over-diagnosis and over-treatment. ⋯ Whether this is clinically important is controversial as it is generally agreed that the natural history of small incidental thyroid cancers is indolent. However a subset may have a more aggressive behaviour and it is not currently possible to predict whether a malignant incidentaloma will progress to clinical disease or remain latent. In this article we review the evidence-base around the current guidelines for investigating thyroid incidentalomas and suggest a practical approach to their management.
