A 22-year-old man was referred to our clinic with a 7-year history of episodes of severe vomiting interspersed with symptom-free periods. We saw another patient, a 22-year-old woman, after she had been admitted for the second time with dehydration and hypokalaemia following severe vomiting. We saw a third patient, a 25-year-old woman with a personality disorder and cannabis addiction, after she had gone to the casualty department following several days of persistent excessive vomiting. ⋯ A subgroup of chronic frequent cannabis users suffer from this syndrome, which can appear for the first time several years after initial cannabis use. The exact mechanism of origin is unknown, though various theories exist. In the case of unexplained chronic symptoms of nausea and vomiting our advice is always to question the patient about substance misuse, and showering and bathing habits.

Case Reports[Popliteal artery entrapment syndrome: suggestions for diagnostic and therapeutic clues].
The popliteal artery entrapment syndrome (PAES) is a rare cause of lower-leg claudication due to an anatomic anomaly along the course of the popliteal artery and sometimes, the vein. In the absence of an anatomic anomaly, it is termed 'functional entrapment'. We present 3 patients: a 13-year-old boy with PAES caused by an anomaly of a tendon, a 46-year-old soldier with functional PAES and a 36-year-old male with venous entrapment. ⋯ In healthy individuals, however, vascular occlusion or stenosis on imaging during provocation testing is considered a physiological finding. Surgery is justified in symptomatic as well as asymptomatic patients with an anatomic anomaly. Surgical exploration of the popliteal fossa should also be considered in patients with functional entrapment, since continuing entrapment may lead to damage of the arterial wall.

Phlebitis is a very common complication of the use of intravenous catheters. Two patients with an i.v. catheter complicated by thrombophlebitis are described. Patient A was immunocompromised due to chronic lymphatic leukaemia and developed septic thrombophlebitis with positive blood cultures for S. ⋯ Risk factors include: female sex, previous episode of phlebitis, insertion at (ventral) forearm, emergency placement and administration of antibiotics. Until recently, routine replacement of peripheral intravenous catheters after 72-96 h was recommended, but randomised controlled trials have not shown any benefit of this routine. A recent Cochrane Review recommends replacement of peripheral intravenous catheters when clinically indicated only.

[Procedural sedation with propofol in non-painful interventions in children].
Propofol is the sedative of choice in our hospital for all procedural sedations in children older than 3 months. Data were collected from all patients who underwent PSA with propofol in the period from November 2007 to December 2009. The procedure was performed by a paediatrician experienced in airway management, sedation and paediatric IC, and a specialized nurse. Patient characteristics, American Society of Anesthesiologists (ASA) classification, vital parameters and propofol dosage were registered on specially designed forms. Patient data were analyzed and compared with data from a non-matched historical cohort of patients who in the past had undergone PSA with chloral hydrate. ⋯ The results suggest that propofol can be used safely and is effective for procedural sedation in selected children, provided that PSA is performed by experienced and trained staff.

Case Reports[A woman with acute loss of vision and a mass in her neck].
A 64-year-old woman had acute central vision loss of her left eye. She also had a pulsating mass in the left side of her neck. It appeared the vision loss was caused by a thromboembolism that originated from an aneurysm of the left carotid artery.
