Rare, potentially fatal, poorly understood propofol infusion syndrome.
We present the case of a 7-year old boy with traumatic brain injury who received propofol during 38 h. Thirty-six hours after cessation of propofol infusion asystole occurred. After immediate mechanical and medical resuscitation, unreactive dilated pupils were observed. ⋯ In this case, metabolic acidosis, cardiac failure, rhabdomyolysis, and renal failure are in accordance with the symptoms of propofol infusion syndrome (PRIS), while seizure, brain edema, and transtentorial herniation could be caused by traumatic brain injury. However, it may be assumed that the entire clinical picture was caused by PRIS. This view could be explained by a common loss of function of ryanodine receptors in patients presenting with PRIS.

Ingestion of a foreign body unmasks an asymptomatic small bowel carcinoid tumor.
Bowel obstruction is a common surgical admission around the world. On the other hand, small intestinal tumors, such as midgut carcinoid, are uncommon neoplasms and an infrequent cause of intestinal obstruction leading to hospitalization. ⋯ Narrowing of the small bowel due to a neoplasm can prohibit the passage of an accidentally ingested foreign object and produce an obstruction that neither the neoplasm nor the foreign body could have produced alone. We hereby report a case in which an accidentally ingested piece of foreign material leads to the finding of a small, early stage, asymptomatic, midgut carcinoid cancer in the proximal ileum that would have otherwise eluded detection for several years.

Severe gastroenteritis as presentation of a primary cytomegalovirus infection in an immunocompetent woman.
In immunocompetent hosts, symptomatic cytomegalovirus (CMV) infection occurs in around 10% and has traditionally been considered to have a benign, self-limiting course. Active CMV infection in immunocompetent subjects is very rare. However, manifestations of CMV infection in immunocompromised hosts have been extensively reported. We present a case of a 58-year-old immunocompetent woman with a primary cytomegalovirus infection which presented as a severe gastroenteritis and hepatitis.

Case ReportsTransient loss of consciousness in a patient with a Brugada like ECG.
Syncope in a patient with a Brugada syndrome channelopathy carries significant prognostic implications and warrants consideration of implantable cardioverter defibrillator (ICD) implantation. We report a case of a 62-year-old gentleman who presented with a transient loss of consciousness and an electrocardiogram (ECG) suggestive of type 1 Brugada syndrome. Further investigation revealed evidence of a silent myocardial infarction and negative ventricular tachycardia stimulation and Ajmaline testing. Careful review of the ECG's subsequently showed the type 1 pattern was present in only V1.

Dexmedetomidine for an awake fiber-optic intubation of a parturient with Klippel-Feil syndrome, Type I Arnold Chiari malformation and status post released tethered spinal cord presenting for repeat cesarean section.
Patients with Klippel-Feil Syndrome (KFS) have congenital fusion of their cervical vertebrae due to a failure in the normal segmentation of the cervical vertebrae during the early weeks of gestation and also have myriad of other associated anomalies. Because of limited neck mobility, airway management in these patients can be a challenge for the anesthesiologist. We describe a unique case in which a dexmedetomidine infusion was used as sedation for an awake fiber-optic intubation in a parturient with Klippel-Feil Syndrome, who presented for elective cesarean delivery. ⋯ Klippel-Feil Syndrome (KFS) is a rare congenital disorder for which the true incidence is unknown, which makes it even rare to see a parturient with this disease. Patients with KFS usually have other congenital abnormalities as well, sometimes including the whole thoraco-lumbar spine (Type III) precluding the use of neuraxial anesthesia for these patients. Obstetric patients with KFS can present unique challenges in administering anesthesia and analgesia, primarily as it relates to the airway and dexmedetomidine infusion has shown promising result to manage the airway through awake fiberoptic intubation without any adverse effects on mother and fetus.
