We present an interesting case of a 49-year-old woman with hypothermia and associated Osborn waves (also called J waves) on ECG. She was found on the floor of her home and difficult to arouse. On arrival to the emergency department (ED), her rectal temperature was 87.5°F. ⋯ She was extubated and was transferred to the medical floor for continued supportive care. Osborn waves on ECG resolved within 12 h of achieving normal range body temperature. The patient was eventually discharged home with medical follow-up.

Vaccine failure is a rare condition and the need to investigate a primary immunodeficiency is controversial. We present the case of a 4-year-old boy, with complete antipneumococcal vaccination, who had necrotising pneumonia with pleural effusion and severe pancytopaenia with need for transfusion. A vaccine-serotype Streptococcus pneumoniae was isolated in the blood culture. ⋯ Dyskeratosis congenita is an inherited disorder that causes shortening or dysfunction of telomeres, affecting mainly rapidly dividing cells (particularly in the skin and haematopoietic system). It leads to bone marrow failure, combined immunodeficiency and predisposition to cancer. The confirmation of this diagnosis allows genetic counselling and medical monitoring of these patients, in order to detect early complications such as bone marrow aplasia or malignancies.

Patients with attacks of re-entrant supraventricular tachycardia (SVT) frequently present to the emergency department (ED). The Valsalva manoeuvre (VM) is the most effective and safe vagal manoeuvre and advocated as the first-line treatment in stable patients but has a relatively low cardioversion success rate. Improving its efficacy would reduce patients' exposure to the side effects and complications of second-line treatments and has other potential benefits. We describe a modification to the VM, which is currently being studied, and present the case of a 23-year-old patient who was successfully treated with this modified VM after a previous near-fatal complication of direct current (DC) cardioversion.

Obesity is an important risk factor for cardiovascular morbidity and mortality. In the UK, one in four people are considered overweight or obese and that number is expected to rise to one in three by 2020. Employees of the National Health Service (NHS) are no exception with up to half of healthcare workers considered overweight or obese. ⋯ Weight gain has been reported during the Christmas period albeit not as much as was traditionally believed according to the results of recent research. Conversely, weight loss has been reported in Muslims who fast during the Islamic month of Ramadan; however, this amount tends to be modest and weight gradually returns to pre-Ramadan status according to a meta-analysis of the literature. We report a case of an NHS healthcare worker - which is the first of its kind that illustrates the role that fasting and other factors have played a role in causing dramatic oscillations in his weight.

Chest X-ray in a 17-year-old boy, presenting with haemoptysis, revealed a radiopaque foreign body (FB) in the right lower lobe. There was no history of aspiration. CT located the needle-shaped FB in the right posterobasal lower lobe segment bronchus. ⋯ In delayed diagnosis of a tracheobronchial FB, CT scan is not only necessary to localise the FB but also to depict or rule out secondary pulmonary changes. Nevertheless, radiolucent components of a metallic FB might be invisible even in CT, leading to underestimation of its size and extension. Late diagnosis complicates removal of tracheobronchial foreign bodies and may even necessitate open surgery, including pulmonary resections.
