Eosinophilic cholecystitis is a rare disease characterized by transmural leukocyte infiltration composed of more than 90% eosinophils. Eosinophilic cholecystitis is clinically indistinguishable from ordinary cholecystitis, and as a rule it leads to cholecystectomy. We report a case of idiopathic eosinophilic cholecystitis treated with steroids. A 75-year-old woman presented with a classic history of acute cholecystitis and a peripheral eosinophilia of 41.8%. There was no evidence of allergy or parasitic infestation. An abdominal ultrasonography and computed tomography (CT) scan showed an edematous, thickened gallbladder wall, but no gallstones. There was no evidence of eosinophilic infiltration in other organs. Cholecystectomy was not performed because the patient refused surgical management. However, fever, abdominal pain, and peripheral eosinophilia persisted despite antibiotic and conservative therapy. Therefore, we attempted treatment with prednisolone. A week later, the symptoms disappeared and the peripheral eosinophilia normalized.

Human sparganosis is caused by the larval tapeworm of genus Spirometra. This parasite commonly invades subcutaneous tissues and muscles. However, infection in the pleural cavity is rare. A 65-year-old male patient, who had undergone surgical excision of subcutaneous masses due to a parasite infection (presumed to have been sparganosis) approximately 10 years ago, showed pleural effusion and peripheral eosinophilia. The anti-sparganum specific IgG antibody levels in the serum and pleural fluid were significantly higher than the normal control levels. Three consecutive doses of praziquantel (75 mg/kg/day) were administered for control of pleural effusion and peripheral eosinophilia. In this patient, sparganosis was suspected, and the probable cause of the infection was ingestion of raw snakes and frogs. Immunoserologic tests using ELISA can be helpful in diagnosis of pleural sparganosis and praziquantel is suggested as an alternative treatment for surgically unresectable cases.

A choledochocele is an expanded sac of the duodenal side of the distal common bile duct (CBD), and is categorized as a type III choledochal cyst. Unlike other choledochal cysts, it can be easily overlooked because of its very low prevalence, non-specific clinical symptoms, and lack of distinctive radiological findings. However, a patient having a repeated pancreaticobiliary disorder with an unknown origin, frequent abdominal pain after cholecystectomy, or repeated non-specific gastrointestinal symptoms can be suspected as having a choledochocele, and a more accurate diagnosis can be achieved via endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound. Because it rarely becomes malignant, a choledochocele can be treated via endoscopic sphincterotomy (EST) and surgical treatment. The authors were able to diagnose choledochocele accompanied by a stone in a patient admitted to the authors' hospital due to cholangitis and pancreatitis. The patient's condition was suspected to have been caused by a distal CBD stone detected via multiple detector computed tomography and ERCP, and was successfully treated via EST.

The common cause of tracheoesophageal fistula(T-E fistula) after tracheal intubation is ulceration and necrosis of the posterior wall of trachea by compression pressure generated by cuff. We experienced a young woman sustaining a T-E fistula which was found on the 12th day of intubation for cardiopulmonary resuscitation. Because spontaneous closure of the fistula is far uncommon, operative closure should be aimed for and should be done as soon as diagnosis is conformed. We delayed operative closure because of poor general condition of the patient. In spite of delayed reconstruction, the tracheal reconstruction itself was successful, but the patient died of peritonitis induced sepsis on the postoperative 41th day.

As in other domains, artificial intelligence is becoming increasingly important in medicine. In particular, deep learning-based pattern recognition methods can advance the field of pathology by incorporating clinical, radiologic, and genomic data to accurately diagnose diseases and predict patient prognoses. In this review, we present an overview of artificial intelligence, the brief history of artificial intelligence in the medical domain, recent advances in artificial intelligence applied to pathology, and future prospects of pathology driven by artificial intelligence.

Intramural pregnancy on a cesarean section scar is one of the rarest forms of ectopic pregnancy that may cause serious complications such as uterine rupture and massive bleeding. The common treatment in the past was laparotomy, but today early diagnosis is available thanks to the development of image diagnostic technology and, as a consequence, cases of less invasive conservative management are reported. Using vaginal ultrasonography and MRI, we made an early diagnosis on a case of intramural pregnancy on the scar of a previous cesarean section. We injected methotrexate locally into the gestational sac, and the intramural pregnancy was completely cured. Thus, here we report this case with a brief review of relevant literature.

Mediastinal hemangioma is a rare tumor and only few cases have been reported in the literatures. We have experienced one case of cavernous hemangioma occuring at the superior vena cana. The patient was a thrity-five year old female with no specific symtoms except palpable cystic mass in the right cervical area. A routine chest radiography showed an upper mediastinal mass. Computed Tomography showed about 4x5 cm sized cystic mass communicating to the superior vena cava 2 cm above of the veno-atrial junction. After the evaluation, surgical excision was performed and the pathologic diagnosis was confirmed to cavernous hemangioma. Postoperative course was uneventful and the patient has been followed up without any problems.

BACKGROUND: Etomidate is used as a fast-acting hypnotic with few cardiovascular effects to induce anesthesia in patients with a poor cardiovascular reserve. The bispectral index (BIS) has been suggested to be a measure of the depth of anesthesia and correlates well with the level of consciousness. This study examined the population pharmacokinetics and pharmacodynamics of etomidate using nonlinear mixed effect (NONMEM) modeling and sigmoid Emax modeling. METHODS: Eighteen middle aged adults, with ASA physical status I or II, who were scheduled for elective surgery, were included. 0.2% etomidate was administerd at 150 ml/h until the patients lost consciousness. The patient recovered spontaneously until they regained consciousness, as determined by a verbal response. The BIS was determined and arterial blood samples were collected. The plasma concentrations were measured with high performance liquid chromatograhy (HPLC). NONMEM was used for population pharmacokinetic and sigmoid Emax model for pharmacodynamic analysis. RESULTS: The induction dose for the loss of eyelid reflexes was 0.38 mg/kg. The induction time from drug infusion to the loss of eyelash reflexes was approximately 3.5 minutes. This study took approximately 8.5 minutes from the start of drug infusion to the recovery of consciousness. The pharmacokinetic parameters were t(1/2alpha) = 1.1 min, t(1/2beta) = 1.9 min, t(1/2gamma) = 106.5 min, k(21) = 0.36 L/min, k(31) = 0.009 L/min, V(1) = 6.43 L, V(area) = 426 L, C(l) = 2.77 L/min. The pharmacodynamics were keo = 0.40 L/min, CE(50) = 1.0 microgram/mL, E(0) = 94, E(max) = 94 and gamma = 1.2. The performance error for the etomidate concentration was 0.14+/-0.99 (typical prediction) and -0.03+/-0.40 (individual prediction) and -0.09+/-1.00 and -0.001+/-0.13 for the BIS score. CONCLUSIONS: When compared with other previously published data, our pharmacokinetic parameters demonstrated a shorter half lives, a larger volume of distribution, and an increased clearance with significant interindividual differences. The pharmacodynamics showed a large interindividual variability. The reason for discrepancy might be the relatively short sampling time. However, further study will be warranted to improve the model performance in the future.
