BACKGROUND:Sushi suffocation is relatively uncommon, and it is an unignorable cause of sudden death; however, no reports on sushi suffocation have been published. METHODS:A 60-year-old man was referred to our hospital for post resuscitative intensive care. He had choked on sushi and collapsed in the dining room of a mental hospital. A nursing assistant summoned a physician who attempted to extract the sushi. External cardiac massage was initiated after 7 minutes had elapsed and followed by endotracheal intubation. Return of spontaneous circulation was achieved after 7 minutes of resuscitation. A bronchoscopy demonstrated a large amount of shari in the trachea and right bronchus, which was removed with alligator forceps and a wire basket. RESULTS:Neurological recovery was evident on day 2 of admission. He was transferred back to the mental hospital with no neurological complications. CONCLUSION:Emergency physicians should consider sushi suffocation, including its clinical features and management.

BACKGROUND: Although non-thyroidal illness syndrome (NTIS) is considered a negative prognostic factor, the alterations in free triiodothyronine (fT3) levels in trauma patients requiring massive transfusion have not been reported. METHODS: A prospective observational study comparing 2 groups of trauma patients was conducted. Group M comprised trauma patients requiring massive transfusions (>10 units of packed red blood cells) within 24 hours of emergency admission. Group C comprised patients with an injury severity score >9 but not requiring massive transfusions. Levels of fT3, free thyroxine (fT4), and thyroid-stimulating hormone (TSH) were evaluated on admission and on days 1, 2, and 7 after admission. The clinical backgrounds and variables measured including total transfusion amounts were compared and the inter-group prognosis was evaluated. Results are presented as mean±standard deviation. RESULTS: Nineteen patients were enrolled in each group. In both groups, 32 were men, and the mean age was 50±24 years. In group C one patient died from respiratory failure. The initial fT3 levels in group M (1.95±0.37 pg/mL) were significantly lower than those in group C (2.49±0.72 pg/mL;P<0.01) and remained low until 1 week after admission. Initial inter-group fT4 and TSH levels were not significantly different. TSH levels at 1 week (1.99±1.64 μIU/mL) were higher than at admission (1.48±0.5 μIU/mL) in group C (P<0.05). CONCLUSION: Typical NTIS was observed in trauma patients requiring massive transfusions. When initial resuscitation achieved circulatory stabilization, prognosis was not strongly associated with NTIS.

BACKGROUND: In approximately 20% of patients, necrotizing pancreatitis is complicated with severe acute pancreatitis, with high morbidity and mortality rates. Minimally invasive step-up approach is both safe and effective, but sometimes requires multiple access sites. METHODS: A 62-year-old woman was admitted with diabetic ketoacidosis, and initial computed tomography (CT) revealed no evidence of acute pancreatitis. She was clinically improved with insulin therapy, fluid administration, and electrolyte replacement. However, on the 14th day of admission, she developed a high-grade fever, and CT demonstrated evidence of acute necrotizing pancreatitis with a large collection of peripancreatic fluid. Percutaneous transgastric drainage was performed and a 14 French gauge (Fr) pigtail catheter was placed 1 week later, which drained copious pus. Because of persistent high-grade fever and poor clinical improvement, multiple 8 and 10 Fr pigtail catheters were placed via the initial drainage route, allowing the safe and effective drainage of the extensive necrotic tissue that was occupying the bilateral anterior pararenal space. RESULTS: After drainage, the patient recovered well and the last catheter was removed on day 123 of admission. CONCLUSIONS: Multiple percutaneous drainage requires both careful judgment and specialist skills. The perforation of the colon and small bowel as well as the injury of the kidney and major vessels can occur. The current technique appears to be safe and minimally invasive compared with other drainage methods in patients with extended, infected necrotic pancreatic pseudocysts.

BACKGROUND:Splenectomy in patients with liver cirrhosis (LC) is expected to become more common owing to its efficacy on portal hemodynamics. In this report we describe an alarming case of group B streptococcus (GBS) infection after splenectomy in a patient with LC. METHODS:A 72-year-old woman with a history of LC was admitted to our emergency department because of respiratory failure. The patient had received left lateral segmentectomy of the liver and splenectomy three months before admission. Pulmonary examination revealed significant wheezing during inspiration and expiration, but no crackles and stridor. Chest radiography and CT showed no infiltrates. A presumptive diagnosis of bronchial asthma caused by upper respiratory infection was made. Four days after admission, GBS infection was confirmed by blood culture and penicillin G was administered. Antibiotics were given intravenously for a total of 12 days. RESULTS:The patient was discharged on the 12th day after admission. CONCLUSIONS:Although efficacy of splenectomy in patients with LC has been reported, immune status should be evaluated for a longer period. Patients who have undergone splenectomy are highly susceptible to bacteria; moreover, LC itself is an independent risk factor for mortality in patients with sepsis. Since prophylaxis against GBS has not been established, immediate action should be taken. Emergency physicians should be aware of invasive GBS infection in the context of the critical risk factors related to splenectomy and LC, particularly the expected increase of splenectomy performed in LC patients.
