Pyoderma gangrenosum (PG) is a reactive non-infectious inflammatory dermatosis falling under the spectrum of the neutrophilic dermatoses. There are several subtypes, with 'classical PG' as the most common form in approximately 85% cases. This presents as an extremely painful erythematous lesion which rapidly progresses to a blistered or necrotic ulcer. ⋯ Treatment of PG remains largely anecdotal, with no national or international guidelines, and is selected according to severity and rate of progression. Despite being a well-recognised condition, there is often a failure to make an early diagnosis of PG. This diagnosis should be actively considered when assessing ulcers, as prompt treatment may avoid the complications of prolonged systemic therapy, delayed wound healing and scarring.

Interpreting pleural fluid results correctly requires an awareness of the possible aetiologies of a pleural effusion and an understanding of the reliability of the outcome of each investigation. All results must be interpreted within each different clinical context and knowledge of the pitfalls for each test is necessary when the diagnosis is unclear. This review aims to discuss the common aetiologies of a pleural effusion and some of the pitfalls in interpretation that can occur when the diagnosis is unclear.

Obesity is a major health and economic crisis facing the modern world. It is associated with excess mortality and morbidity and is directly linked to common conditions such as type 2 diabetes mellitus, coronary heart disease and sleep apnoea. The management of obesity and its associated complications has evolved in recent years, with a shift towards more definitive strategies such as bariatric surgery. This review encompasses the dietary, pharmacological and surgical strategies currently available for the management of obesity.

The use of regular infusions of immunoglobulin is well established as a treatment for patients with antibody deficiency and for patients requiring immunomodulation. Although efficacy is believed to be equivalent for the different immunoglobulin products, it is generally regarded as best practice not to switch from one product to another unless there is a clinical reason to change. Changes in commissioning guidance and issues with the supply of some immunoglobulin products to the UK resulted in a requirement for a significant number of patients to switch between immunoglobulin products in 2017-2018. ⋯ Results from 30 immunology centres reported a total of 802 immunoglobulin product switches. Twelve reactions were recorded, none of which required admission to hospital, one patient was treated with oral corticosteroids, the others required either no treatment or treatment with oral antihistamines. This review of immunoglobulin product switch reactions gives a clearer indication regarding the safety of product switching than has previously been published.

Case Reports
Lesson of the month 2: Fever, arthralgias and hyperkeratotic, scaling and fissuring eruptions of the hands.
A 56-year-old male hairdresser, presented with fever and arthralgias. He had a worsening 'eczematous' palmar rash which had been attributed to irritation from colouring products used in his work. On examination, hyperkeratotic, fissuring eruptions were noted on the palmar side of his fingers and lung auscultation revealed crackles on both lower lobes. ⋯ This is a characteristic semiology reminiscent of hands of manual workers, resembling hand eczema. 'Mechanic's hands', fever, arthralgias, lung findings and elevated serum muscle enzymes raised the possibility of antisynthetase syndrome. Testing for myositis autoantibodies revealed anti-Jo-1 and anti-Ro52 reactivity supporting the diagnosis. Greater awareness of the typical clinical feature of 'mechanic's hands' will allow for earlier diagnosis and appropriate treatment in patients with antisynthetase syndrome.
