Ketotifen, a benzocycloheptathiophene, has an orally effective antiallergic as well as antihistaminic properties. In pervious studies, Ketotifen has shown encouraging results on patient with allergic rhinitis, either perennial or seasonal. 39 patients with allergic rhinitis had been treated with Ketotifen 1 mg twice daily for 8 weeks. And we obtained following results. 1) The efficacy rate in sneezing attack was 73.5%, in nasal discharge 71%, in nasal obstruction 58%. 2) Some improvements in at least one of three-major symptoms were noted within 1 week in 30.7%, within 2 weeks in 55.8%, within 3 weeks in 66.7%, within 8 weeks in 87.2%. 3) Physical findings such as colour, swelling of turbinate, character of rhinorrhea were not improved significantly. 4) Side effect was observed only in one patient with abdominal pain and diarrhea, which was subsided after interruption of administration. These results suggested that Ketotifen was effective in treatment of allergic rhinitis.

BACKGROUND: The purpose of our study was to evaluate the accuracy of reduction based on postoperative computed tomography (CT) images after arthroscopic stabilization using tightrope system for unstable distal clavicle fracture. METHODS: Twelve patients with distal clavicle fracture combined with coracoclavicular (CC) ligament injury (type II, V) who received arthroscopically assisted fixation using a flip button device were evaluated for accuracy of reduction using 3-dimensional postoperative CT scan by measuring the degree of distal clavicular angulation and clavicular shortening. RESULTS: Immediate postoperative plain radiograph confirmed restoration of the CC distance (CCD) in 10 patients. At final follow-up, the CCD remained reduced anatomically on plain radiographs in these patients. All patients showed excessive posterior angulation and shortening compared to the opposite side. The average Constant score recovered to 94.8 at final follow-up. CONCLUSIONS: Indirect reduction and arthroscopic subacromial approach with flip button fixation of unstable distal clavicle fractures demonstrated favorable clinical results despite unavoidable posterior angulation of distal clavicle and shortening the total length of clavicle.

PURPOSE: Laparoscopy-assisted distal gastrectomy (LADG) is gaining wider acceptance for the treatment of early gastric cancer. However, firm evidence supporting the long-term outcome after LADG for gastric cancer is unknown. This study compared long-term quality of life after LADG versus an open distal gastrectomy (ODG) for early gastric cancer. METHODS: This study included 29 patients who underwent LADG and 57 patients who underwent ODG for the treatment of stage I gastric cancer. Quality of life was evaluated based on the Korean version of EORTC QLQ-C30 (version 3.0) and EORTC QLQ-STO22 one year after surgery. All patients underwent a Billroth II gastrectomy for stage I gastric cancer between January 2003 and December 2004. RESULTS: A total of 86 (58%) out of 154 patients responded to the questionnaire. Demographic features showed no difference between the two groups of patients for age, sex, depth of invasion, lymph node metastasis except for tumor size and the number of retrieved lymph nodes. The mean score for global health status was not statistically different (LADG, 60.3+/-20.4 vs ODG, 57+/-20.6; P=0.413). The total score of 21 items related to stomach cancer (EORTC QLQ-STO22) also was not statistically different (LADG, 68.9+/-64.9 vs ODG, 94.5+/-97.3; P=0.340). CONCLUSION: Based on the results of the Korean version of EORTC QLQ-C 30 (version 3.0) and EORTC QLQ-STO22, LADG does not seem to have any long-term benefit over ODG on 'quality of life'.

Accurate diagnosis and management of a femoral vascular injury is important as it is a life-threatening injury with high morbidity and mortality. This is the case of a 75-year-old man admitted to the emergency room with trauma to the right groin due to a horse fall. Computed tomography showed active bleeding of the femoral artery without pelvic or femoral fracture. We inserted a stent-graft, but hypotension persisted. Exploration of the groin was completed, and the bleeding from the external iliac vein was identified and repaired. In conclusion, vascular injury is rare in groin trauma without associated fracture, however, arterial and venous injury should not be completely ruled out. Endovascular therapy is worth recommending as a quicker and safer management than surgery in patients with active bleeding in the femoral artery. However, the possibility of combined injury of the femoral vein should be suspected in case of ongoing hemodynamic instability.

Arteriovenous fistulae(AVF) are well documented complications of percutaneous renal biopsy. Between August 1995 and April 1997, we prospectively studied 280 consecutive ultransound-guided percutaneous renal biopsies to evaluate the incidence of post-biopsy AVF and its natural course. All biopsies patients were monitored through a routine follow-up echo-color popple sonography at post-biopsy 1, 7, 14 and 30 days. The 28 patients(10%) out of 280 consecutive percutaneous renal biopses were diagnosed to have AVF. There was no differences in the incidence of AVF between native and transplanted kidney biopsy. Most AVF were small(<2cm) and caused minimal or no symptoms. AVF was accompanied with large hematoma(thickness above 2cm) was observed in 9 cases(53%) of 17 native kidneys and none in 10 transplanted kidneys. This difference was statistically significant(P=0.008). At follow-up, AVF resolved spontaneously in 24 cases(87%). In two patients(7.1%) required superselective arterial embolization, one develoved spontaneous rupture of AVF, and one had persistence of AVF over 12 months. We concluded that color Doppler sonography provides a good, non-invasive and safe method for diagnosis and follow up of post-biopsy AVF.

Arachnoid cyst develops due to cerebrospinal fluid increase in the subarachnoid space and is mostly located in the middle cranial fossa, which may be associated with non-specific symptoms such as headache, unsteadiness and ataxia. However, it rarely occurs in the posterior cranial fossa and is mostly asymptomatic. When symptoms do develop, they are usually headache and psychomotor retardation, which make diagnosis very difficult. Diagnosis is generally made through magnetic resonance imaging and surgical treatment is indicated for cases where there are displacement and compression of its surrounding neurovascular component, and aggravation of symptoms. We present a case of unilateral sudden hearing loss possibly developing from an arachnoid cyst in the posterior cranial fossa with a review of literatures.

PURPOSE: Phenylbutyrate is an effective redifferentiating agent in several human cancers. Recently phenylbutyrate has been reported to inhibit histone deacetylase activity. We investigated the effects of sodium 4-henylbutyrate (Na-4-PB) on cell proliferation in a human pancreatic cancer cell line. METHODS: A human pancreatic cancer cell line, Aspc-1 was purchased from Korean Cell Line Bank. Antiproliferative effects of sodium 4-phenylbutyrate were measured by MTT assay and their mechanisms were evaluated by apoptosis assay and cell cycle analysis. RESULTS: After 3 days of treatment with Na-4-PB at the concentration of 2.5, 5, 7.5, and 10 mM, relative growth inhibition compared to control was 21.3+/-8.3% (mean+/-SD), 37.8+/-2.3%, 46.7+/-0.5%, and 56.7+/-1.7% respectively (p < 0.05). Antiproliferative effect of Na-4-PB was also time-dependent. Combination treatment with Na-4-PB and troglitazone, a PPARg agonist, increased antiproliferative effects but was not synergistic. After 48 hour treatment with Na-4-PB, early apoptotic cell population in control, 2.5, and 5 mM of Na-4-PB was 29.6%, 44.2%, and 65.9%, respectively. After 24 hour treatment with Na-4- PB, G0/G1 phase population in control, 2.5, and 5 mM of Na-4-PB was 55.0%, 67.4%, and 65.8%, respectively. CONCLUSION: Na-4-PB inhibited pancreatic cancer cell proliferation by inducing apoptosis and cell cycle arrest at G0/G1 phase in time- and dose-dependent manner. Combination treatment with Na-4-PB and other chemotherapeutic agents such as troglitazone, a PPARg agonist, can enhance antiproliferative effects. Na-4-PB might be a promising potential therapeutic agent for patients with pancreatic cancer.

PURPOSE: Tumor necrosis factor-alpha(TNF-alpha) is a pro-inflammatory cytokine that has been implicated in the pathogenesis of cardiovascular disease. Serum levels of TNF-alpha are elevated in many human cardiac related pathogenic conditions, including heart failure. It is well known that TNF-alpha inhibits myocardial contractility and induces apoptosis of adult rat cardiomyocytes via stimulation of TNF receptor 1. But pathophysiologically relevant low levels of TNF-alpha can not induce apoptosis of neonatal cardiomyocytes. So, we evaluated the effects of different concentrations of TNF-alpha in cultured rat neonatal cardiomyocytes : apoptosis or necrosis. METHODS: Neonatal ventricular myocytes were isolated from 3-day-old rats by stepwise collagenase dissociation, and the cells were cultured for 3 days. After that, cardiomyocytes were treated with low(25 ng/mL) and high(250 ng/mL) concentration of TNF-alpha for 48 hours. Apoptosis was determined by terminal deoxynucleotidyl transfer-mediated end labelling(TUNEL) staining, and cell viability was evaluated by lactate dehydrogenase(LDH) measurements using cell culture supernatants. RESULTS: Low dose TNF-alpha did not induce apoptosis compared with controls(10.5 +/- 3.5% : 10.4 +/- 4.3%). And high dose TNF-alpha also did not induce significant apoptosis(10.2 +/- 3.6% : 10.4 +/- 4.3%). There was no detectable morphological changes of cardiomyocytes after low and high concentration of TNF-alpha treatment. LDH levels after TNF-alpha treatment was not significant compared with control(control : low : high, 3.2 +/- 0.1% : 3.1 +/- 0.2% : 3.3 +/- 0.3%). CONCLUSIONS: Our results suggest that high concentration of TNF-alpha alone can not induce apoptosis and significant cytotoxicity in neonatal rat cardiomyocytes.
