Stroke is a debilitating complication of cardiac surgery. Many intraoperative and postoperative factors predict the likelihood of post-cardiac surgery stroke. We evaluated preoperative parameters, seeking correlations with adverse neurological outcome following cardiac surgery. We investigated the possibility of preoperative carotid ultrasonography to select patients for carotid endarterectomy pre- or intraoperatively. ⋯ The stage of cardiac disease (risk factor level, ejection fraction and presence of carotid stenosis) correlates with stroke and may predict an adverse neurological outcome.

Tuberculosis involving the thyroid gland is a rare occurrence. We report a case of cytologically-diagnosed thyroid gland tuberculosis in a 21-year-old man who presented with thyroid swelling of short duration, and describe the magnetic resonance (MR) imaging appearances of the lesion, which to our knowledge, has not been previously described. We also report a rare complication of abscess formation in the track of the fine needle aspiration. The intermediate signal intensity of the lesions on both T1- and T2-weighted MR images may provide a clue about tuberculosis, as clinical suspicion is low due to the rarity of the disease.

Case Reports
Tenosynovial giant cell tumour of the posterior cruciate ligament and its arthroscopic treatment.
Tenosynovial giant cell tumours originate from synovial tissues of the joints, tendon sheaths, mucosal bursas or fibrous tissues adjacent to tendons. Tenosynovial giant cell tumours are rarely intra-articular. We report a giant cell tumour of the tendon sheath arising from the posterior cruciate ligament diagnosed by magnetic resonance imaging and resected arthroscopically in a 54-year-old woman.

Noninvasive ventilation (NIV) with continuous positive airway pressure (CPAP) has been shown to decrease endotracheal intubation and mortality in patients with acute cardiogenic pulmonary oedema (ACPE). The Three Interventions in Cardiogenic Pulmonary Oedema showed no advantage of NIV over standard medical therapy. This meta-analysis is an update on the efficacy and safety of two different forms of NIV (noninvasive pressure support ventilation [NIPSV] vs. CPAP) in patients with ACPE. ⋯ NIPSV appears to be as safe and efficacious as CPAP, if titrated rather than fixed pressures are employed.
