Authors report two cases of hypothermic patients with Osborne's J wave on electrocardiogram. A 46-year-old male with liver cirrhosis was brought to the emergency room by ambulance due to comatous mental status. On exammination, the body temperature was below 35 degree C. By rewarming using warm normal saline intravenous infusion and hot pack application on the chest, his body temperature rose up to 36 degree C and regained consciousness. Later, he expired with afterdrop phenomenon. Another 41-year-old stuporous quadriplegic male with post-traumatic cerebral palsy was brought to the emergency room by his family complaining weakness and vomiting. On exammination, the body temperature was below 35degree C. He was rewarmed using warm normal saline intravenous infusion and hot pack application on the chest. However, he could not regain his normal body temperature and expired due to irreversible shock.

Undifferentiated sarcoma is one of the rare primary malignant tumor of the liver typically occur ring in later childhood. It has also been referred to embryonal sarcoma or malignant mesenchymoma. In Korea, three child and two adult cases have been reported to date in liter ature. We experienced a case of undifferentiated sarcoma in a 65- year- old female who presented with abdominal pain and right upper quadrant mass . Contrast-enhanced abdominal CT scan revealed a well demarcated mass with low at tenuation and sept ation at left lobe of the liver and the mass showed hypovas cular pattern on hepatic angiography. On cross section, the tumor was well demarcated from the adjacent liver by afibr ouspseudocapsule and showed cystic degener ation. Pathologically, the tumor was consistent with an undifferentiated sarcoma of the liver.

Herpes simplex virus (HSV) is a recognized cause of gastrointestinal infection in immunodeficient patients. Although a few cases of HSV gastritis and colitis in immunocompromised patients have been reported, there are no reports of HSV duodenitis in patients with Crohn's disease (CD). A 74-year-old female was admitted with general weakness and refractory epigastric pain. She had been diagnosed with CD three years ago. Esophagogastroduodenoscopy (EGD) revealed diffuse edematous and whitish mucosa with multiple erosions in the duodenum. Considering the possibility of viral co-infection, cytomegalovirus (CMV) immunohistochemical staining, PCR, and cultures of duodenal biopsies were performed, all of which were negative with the exception of the isolation of HSV in culture. After administration of intravenous acyclovir for 1 week, follow-up EGD showed almost complete resolution of the lesions and the patient's symptoms improved. In CD patients with refractory gastrointestinal symptoms, HSV, as well as CMV, should be considered as a possible cause of infection, so that the diagnosis of viral infection is not delayed and the appropriate antiviral treatment can be initiated.

A 39-year-old man with a history of hypertension for 10 years and 10 pack-years smoking, was admitted with dyspnea and generalized edema. On admission, renal insufficiency accompanied with nephrotic syndrome was diagnosed. Even on careful examination including history, blood chemistry test, and fundoscopic examination, no clinical evidence of diabetes was found. Renal biopsy findings, which strongly resembled that of diabetic nodular glomerulosclerosis in microscopic features, showed glomerular hypertrophy and nodular mesangeal sclerosis. Additional immunohistochemistry and ultrastructural investigations excluded other possible diseases that should be differentiated; membranoproliferative glomerulonephritis, thrombotic microangiopathy, amyloidosis, monoclonal immunoglobulin deposition disease, fibrillary glomerulonephritis, and immunotactoid glomerulopathy. Idiopathic nodular glomerulosclerosis is histopathologically similar to nodular diabetic glomerulosclerosis but is unusually developed in persons with hypertension and smoking history. Though there were three reports about cases of nodular glomerulosclerosis in the Korean literature, the cases were related to hepatitis B virus or diabetic retinopathy without overt diabetes. We report a rare case of idiopathic nodular glomerulosclerosis that was related to hypertension and smoking without other medical history.

The incidence of heterotopic ossification in adolescents appears to be lower than in adults. There exist very few reports of heterotopic ossification with total bony ankylosis in child or adolescent populations. We describe a case of total bony ankylosis of the elbow secondary to heterotopic ossification, in a 14-year-old female. Total ankylosis of the elbow at 45 degrees of flexion was noted 6 months post-surgery, and complete surgical excision of the heterotopic mass was performed. After an additional one-time dose of radiation therapy and nonsteroidal anti-inflammatory drug medication, full range of motion was obtained without any recurrence or other complications, up to the last follow-up of 30 months.

PURPOSE: To investigate the incidence and associated factors of delirium after orthopedic surgery. MATERIALS AND METHODS: A total of 2,122 cases, who were older than 20 years and underwent orthopedic surgery at a single medical center during a one year period were included. Among them, 132 patients who were diagnosed with delirium after surgery under the Diagnostic and Statistical Manual of Mental Disorders-V criteria and medicated under the consultation of a psychiatrist were included in the study The differences in the incidence of delirium and several affecting factors were analyzed. RESULTS: The overall incidence of delirium after surgery was 6.2% (132 in 2,122 cases). The mean age of the delirium group was 77.4 years (range, 54–92 years), which was higher than that of the non-delirium group (58.1 years). The percentage of women in the delirium group was 63.6% (84 in 132 cases), which was higher than that of the women in the non-delirium group (49.0%). The incidence of delirium after surgery was 9.3% (85 in 916 cases) due to trauma and 3.9% (47 in 1206 cases) due to disease. The incidence of postoperative delirium according to the surgical region was 29.2% (7 in 24 cases) in two or more regions, 13.7% (72 in 526 cases) in the hip, and 9.6% (14 in 146 cases) in the spine, 3.5% (20 in 577 cases) in the knee-lower leg, 2.5% (5 in 199 cases) in the foot-ankle, 2.4% (11 in 457 cases) in the shoulder-elbow, and 1.6% (3 in 189 cases) in the forearm-wrist-hand. Delirium occurred more rapidly in women and surgery due to disease, and the duration of delirium was longer in patients with dementia and major depressive disorders. CONCLUSION: The incidence of postoperative delirium was high in cases of surgery due to trauma and in cases of surgery in two or more sites. The incidence of postoperative delirium according to a single surgical region was higher in the order of the hip, spine, and knee. Active intervention is needed regarding the correctable risk factor.

Rectus muscle hematoma is uncommon condition, caused by a tear in an epigastric vessel. Most cases were caused by direct trauma or anticoagulation therapy. In addition, it has been frequently associated with other conditions such as coughing, sneezing, vomiting, pregnancy, hypertension, prior paracentesis or laparotomy, excessive retraction in surgery. There are several reports of rectus muscle hematoma in renal failure, but no report has come out with CAPD patients in Korea. We herein present a case of rectus muscle hematoma due to severe cough in end-stage renal disease patient on CAPD.

The purpose of this study is to evaluate prospectively the effect of different bonding systems and retention grooves on the clinical performance of resin restorations in non-carious cervical lesions (NCCLs). Thirty-nine healthy adults who had at least 2 NCCLs in their premolar areas were included in this study. One hundred and fifty teeth were equally assigned to six groups: (A) Scotchbond Multi-Purpose (SBMP, 3M ESPE, St. Paul, MN, USA, 4th generation bonding system) without retention grooves; (B) SBMP with retention grooves; (C) BC Plus (Vericom Co., Anyang, Gyeonggido, Korea, 5th generation bonding system) without retention grooves; (D) BC Plus with retention grooves; (E) Adper Prompt (3M ESPE, Seefeld, Germany, 6th generation bonding system) without retention grooves; (F) Adper Prompt with retention grooves. All cavities were filled with a hybrid composite resin, Denfil (Vericom Co., Anyang, Gyeonggido, Korea) by one operator. Restorations were evaluated at baseline and at 6-month recall, according to the modified USPHS (United States Public Health Service) criteria. Additionally, clinical photographs were taken and epoxy resin replicas were made for SEM evaluation. At 6-month recall, there were some differences in the number of alpha ratings among the experimental groups. But, despite the differences in the number of alpha ratings, there was no significant difference among the 3 adhesive systems (p > 0.05). There was also no significant difference between the groups with or without mechanical retention (p > 0.05). Follow-ups for longer periods than 6 months are needed to verify the clinical performance of different bonding systems and retention grooves.

Gallbladder (GB) cancer occurs predominately as a biliary tract malignant tumor. It generally has a very poor prognosis, and early detection is often difficult. A variety of carcinogens have been implicated as an important cause for GB cancer. Benzene is a well-known carcinogen for hematologic malignancy, and its casual relationship with GB cancer has been suggested. We report a case of two patients who had operated a laundry cleaning facility together and later simultaneously got GB cancer after prolonged benzene exposure.
