Transarterial chemoembolization (TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). The most common complications after TACE are non-specific symptoms called post-embolization syndrome, such as abdominal pain or fever. Rare complications, such as liver failure, liver abscess, sepsis, pulmonary embolism, cholecystitis, can also occur. On the other hand, gallbladder perforation is quite rare. This paper reports a case of gallbladder perforation following TACE. A 76-year-old male with a single 9-cm-sized HCC underwent TACE. Five days after TACE, he developed persistent right upper quadrant pain and ileus. An abdomen CT scan confirmed gallbladder perforation with bile in the right paracolic gutter and pelvic cavity. Percutaneous transhepatic gallbladder drainage was performed with the intravenous administration of antibiotics. After 1 month, the patient underwent right hemihepatectomy and cholecystectomy. Physicians should consider the possibility of gallbladder perforation, which is a rare complication after TACE, when unexplained abdominal pain persists.

PURPOSE: There has been various reports on the inverse association between coffee consumption and serum gamma-glutamyltransferase(GGT) activity in the general population of Western countries. However, this association is uncertain in the communities in which coffee consumption is less popular. So we tried to identify this association in men of rural area in Korea. METHODS: We examined the association between coffee consumption and serum GGT activity in cross-sectional study involving 379 male population health examinees aged 40 years and older from rural areas in Kyungnam prefecture in Korea. Those who perceived their health status as poor were excluded. Possible confounding effects of age, body mass index, alcohol consumption and cigarette smoking were controlled by multiple regression analysis and analysis of covariance. RESULTS: In multiple regression analysis, serum GGT activity was positively associated with alcohol intake, body mass index(P<0.001) and was negatively associated with coffee consumption(P=0.022), whereas no significant association was observed in cigarette smoking(P=0.094). Adjusted serum GGT activity level at the coffee consumption level of 0, one and two or more cups a day was 37.6 U/l, 35.9 U/l and 26.8 U/l respectively(Ptrend=0.008). CONCLUSION: Decreased serum GGT activity appears to be associated with coffee consumption in men of rural area, and further studies on the interrelationships among coffee consumption, alcohol intake and obesity will be necessary.

With the increasing use of primary hip arthroplasty for management of intertrochanteric fractures, firm fixation and union of the greater trochanteric (GT) fragment are required during hip arthroplasty for management of intertrochanteric fractures. Various methods have been suggested to address this issue. However, displacement of the GT is a frequent occurrence. We have introduced a cement-filling technique for performance of hip arthroplasty of the proximal femur for achievement of immediate firm fixation of the GT. Cement filling during performance of hip arthroplasty for management of femoral intertrochanteric fractures is a valuable technique for preventing displacement of the GT and to encourage early mobilization.

OBJECTIVE: Workload is known to affect the hypothalamus-pituitary-adrenal axis. Although many studies had revealed that job stress related factors could affect the neuroendocrine system among blue-collar workers, these studies had limitations as they had not evaluated the workload by objective methods which took into consideration individual physiological differences. This study was conducted to evaluate the effects of physical workload adjusted job stress on cortisol regulation by using objective tools for workers having various job tasks. METHODS: Among 110 foundry workers, shipyard workers, and fine machine assemblers for whom saliva samples were obtained, 102 without any past history of conditions that could affect hormonal regulation such as diabetes, and hypertension were included in this study. Among the 102 study participants, 15 workers whose saliva for morning or afternoon or heart rate monitoring data was not attained were excluded from the final analysis. Workload was evaluated by RHR (relative heart rate) using a heart rate monitor, and job stress was evaluated by Karasek's Job Content Questionnaire. Saliva samples were gathered during 8 - 9 am and 5 - 6 pm, and salivary cortisol levels were analysed by radioimmunoassay. RESULTS: After adjusting several variables which could effect cortisol secretion including job stress, among the higher RHR group morning salivary cortisol level was increased (beta=60.32, S.E.=26.35, p=0.0266), afternoon salivary cortisol level was decreased (beta=-7.43, S.E.=29.73, p=0.8044), and salivary cortisol level difference between morning and afternoon was increased (beta=72.10, SE=35.50, p=0.0509). CONCLUSIONS: As physical workload increases morning cortisol level, which is caused by the effect of arousal, and decreases afternoon cortisol level, which is caused by exhaustion, physical workload enlarges the width of diurnal cortisol variance. Therefore, physical exhaustion due to excessive workload could have adverse effects on the neuroendocrine system.

PURPOSE: We wanted to compare the clinical and radiological results of surgical treatment of acetabular both column fracture according to the fixation method. MATERIALS AND METHODS: Between 1986 and 2008, 55 patients who underwent surgical treatment for acetabular both column fracture were clinically and radiologically evaluated after a minimum follow-up of one year. Of 55 patients, 29 cases were operated with a cerclage wire or cable (group I) and 26 cases were operated with a plate and screw (group II). The surgical approach, the intra- and post-operative complications and the reduction quality were compared between the two groups. The clinical and radiological results were analyzed according to the criteria reported by Matta. RESULTS: There were 14 (48.3%)/20 (76.9%) cases of anatomical reduction, 12 (41.4%)/6 (23.1%) cases of imperfect reduction, 1/0 case of poor reduction and 2/0 cases of surgical secondary incongruence, respectively. Thirty three patients of 34 anatomically reduced patients showed excellent clinical results and the anterior and posterior combined approach was frequent in group I. There were no differences between the two groups for the complications, although intraoperative complication was more frequent in group II and postoperative complication was more frequent in group I. CONCLUSION: The clinical and radiological results of surgical treatment in patients with both column fracture were satisfactory in both groups. However, the concerns related to the surgical approach and complications will require a randomized prospective study.

PURPOSE: The purpose of this study was to observe and compare the changes in the patterns of hemodynamic and blood profiles on the circuit of Extra-corporeal life support system (ECLS) by using a dual pulsatile pump (T-PLS). METHODS: An acute heart failure model using partial pulmonary artery banding was constructed in 12 piglets (20 -25kg). The animals were divided into centrifugal (n=6) and dual pulsatile pump (n=6) group. Each animal was placed on an ECLS system with a membrane oxygenator bypassing the right atrium and the aorta for 2 hours under general anesthesia. The parameters mainly observed were intra-circuit pressure changes, arterial pulsatility (pulse pressure), plasma free hemoglobin, hemodynamic changes, and other blood profiles. The parameters obtained just prior to the bypass were compared with the corresponding parameters obtained two hours after the bypass. RESULTS: Before bypass, the parameters were statistically the same between the groups. Two hours after the bypass, no significant differences were observed between the groups in ABGA, VBGA, AST/ALT, BUN/Cr, and electrolytes; the plasma free hemoglobin was 14.8+/-4.7 g/dl in the dual pulsatile group and 19.1+/-9.1 g/dl in the centrifugal group (p=NS). The pulse pressure was higher in the dual pulsatile pump than in the centrifugal pump group (35+/-8 vs. 11+/-7 mmHg, p=0.0253 mmHg). The highest circuit pressure was generated at the inlet of the membrane oxygenator and was higher in the dual pulsatile group than in the centrifugal group (173+/-12 mmHg vs. 222+/-8 mmHg, p=0.0000). CONCLUSION: The results demonstrate that a dual pulsating mechanism lessens blood cell trauma while providing physiologic pulsatile blood flow. The ECLS system using a dual pulsatile pump (T-PLS) can be useed as an effective and safe driving motor for an ECLS.

Neurogenic tumors of the brachial plexus region are relatively rare. We report a recent experience of schwannoma of the right brachial plexus in the inferior trunk, which was successfully treated by microsurgical resection. A 38-year- old man presented a dysesthetic pain in the supraclavicular area and the right forearm of C6, 7 dermatome. Rubbery hard mass was palpated in the right supraclavicular area and magnetic resonance imaging showed a well circumscribed, well enhanced ovoid mass with cystic degeneration on the right brachial plexus portion. The patient underwent complete removal of the mass through the anterior cervicothoracic (modified Dartevelle) approach. At the postoperative 3 months, there is no neurologic deficit.

Acute otitis media (AOM) is one of the most common childhood infectious diseases. Despite antibiotic treatment for AOM, AOM and its complication still continue to develop. Acute mastoiditis is a serious complication of AOM and epidural abscess constitutes the commonest of all intracranial complication of AOM. Neurological complication of acute mastoiditis are rare but can be life threatening. Their presentation may be masked by the use of antibiotics. We report the rare case of acute otitis media progressing to acute mastoiditis, epidural abscess formation and lateral sinus thrombophlebitis caused by Streptococcus pneumoniae in a child. She was admitted with acute otitis media with fever. Despite proper antibiotics, acute mastodititis and epidural abscess were developed, and after surgical drainage and antibiotics therapy she was recovered without sequalae.

PURPOSE: Acute appendicitis is one of the most common surgical emergencies worldwide. Laparoscopic appendectomy (LA) is being accepted as the 'gold standard' surgery for simple acute appendicitis over open appendectomy (OA); however, for complicated appendicitis, no consensus has been reached with regard to which produces better outcomes. METHODS: We analyzed the data of patients who were diagnosed as complicated appendicitis, older than 18 years old, and underwent LA or OA from January 2008 to December 2012. A total of 2,173 patients had acute appendicitis during this period and 461 (21.2%) of them had complicated appendicitis; 335 patients were finally enrolled and divided into LA (280), OA (49), and Converted to open Appendectomy (CA) groups (6), respectively. Age, sex, preoperative WBC, operating time, stapler usage, time to diet and discharge, total cost and complication among the three groups were analyzed. RESULTS: No significant differences were observed in sex, age, history of abdominal surgery, preoperative WBC, and total cost. Shorter operating time (62.3+/-30.0 vs 87.3+/-40.2, p=0.000), shorter time to diet (2.7+/-2.2 vs 3.7+/-1.6, p=0.001), shorter postoperative stay (4.8+/-2.6 vs 7.1+/-2.5, p=0.000), shorter duration of pain (3.4+/-1.7 vs 5.6+/-2.8, p=0.000), and less frequent usage of pain killer (68.2% vs 89.1%, p<.001) were observed in the laparoscopic group. Complication rate was significantly lower in the LA group (4.6% vs 18.4%, p=0.002). CONCLUSION: Results of this study provide clinical evidence that laparoscopic surgery is a feasible and safe surgical modality for complicated appendicitis. Conduct of more reliable, large scaled, randomized prospective study will be necessary in order to prove the superiority of laparoscopic surgery for complicated appendicitis.
