BACKGROUND: Video assisted thoracic sympathectomy or sympathicotomy is a safe and effective therapy for the treatment of palmar hyperhidrosis with immediate symptomatic imporvement. However the degree of satisfaction may diminish with time due to cmpensatory sweating or excessive hand dryness. Therefore by comparing and assessing the degree of symptomatic improvement or compensatory sweating following sympathectomy or sympathicotomy at various levels we aim to determine the optimal level of sympathetic nerve block which will result in minimal side effects and maximal benefit. MATERIAL AND METHOD: Among 194 patients having undergone video assisted thoracic sympathectomy or sympathicotomy between January 1996 and June 1999, 137 patients who responded to either telephone interview or questionnaire were included in the current study. The patients were divided into three groups. Group I(n=61) ; patients having undergone T2,3,4 sympathectomy group II(35) ; patients having undergone T2 sympathicotomy and group III(41) ; patients having undergone limited T2 sympathicotomy which consist of block of interganglionic neuronal fiber on the third rib. The parameters studied comprised of pre- and post-operative palmar temperature change treatment satisfaction the degree of compensatory sweating or discomfort from palmar dryness postoperative complication and changes in plantar sweating. RESULT: There was no difference in age and sex among the groups and the mean postoperative elevation in palmar temperature was 21.59degrees C without any differences among the groups. Patients expressing satisfaction were 65.6%, 62.9% and 90.24% in groups I, II and III, respectively(p<0.05) Moderate to severe compensatory sweating was present in 65.6% 51.4%, and 24.39%, in group I, II, and III, respectively (p<0.05) Slight but comfortable amount of palmar humidness was expressed in decreasing order group III(41.6%) group I(24.6%) and group II(5.7%) (p<0.05) Ineffectiveness or recurrence was present in 5patients in group I(8.2%) 1 patient in group II(2.9%) and none in group III. With regards to plantar sweating decrease in sweating was expressed in 43 patients(31.4%) while similar degree of sweating in 61 patients(44.5%) and increase in sweating in another 33 patinets(24.1%). CONCLUSION: Limited T2 sympathicotomy resection of the lower interganglionic neuronal fiber of the second sympathetic ganglion on the third rib showed immediate effect in palmar hyperhidrosis and caused lesser compensatory sweating and hand dryness.

PURPOSE: We evaluated the MR and CT findings of the masticator space lesions in order to identify the differences among the malignant and benign tumors and infectious conditions. MATERIALS AND METHODS: MR and CT findings in 46 cases with proven masticator space lesions were reviewed retrospectively. We analysed the involvement of masticator muscles, adjacent spaces, orbit and intracrahium, homogeneity, necrosis, cystic changes, growth patterns, calcifications, enhancement patterns, MR signal intensity, and CT attenuation. RESULTS: Among the 29 cases of malignant tumors, seven cases were mandibular tumors including four chondrosarcomas, and 22 cases were extramandibular tumors. Malignant tumors of mandibular origin showed large masses with severe bone destruction and epicenter of mandible. Extramandiblular malignant tumors showed the epicenter out of the mandible and less severe bone destruction than mandibular tumors: Among the nine benign tumors, four cases were ameloblastomas which showed the well-defined masses and the expansion of the mandible, and four cases were extramandibular tumors which showed well-marginated extramandibular masses with no bone destruction. Among the eight infectious conditions, five cases were mandibular osteomyelitis with or without abscess formations, and the other three cases were infections from adjacent soft tissue or limited to the soft tissue. CONCLUSION: By careful observations of growth patterns, involvement of the masticator and adjacent spaces, bone changes, and epicenter of the lesions, one can discriminate a mandibular lesion from an extramandibular lesion. With this approach, it is thought to be easier to suggest a dignosis among a wide spectrum of masticator lesions.

Primary amenorrhea due to intrasella arachnoid cyst is a very rare disease and require careful and frequent evaluation because may produce intracranial hemorrhage, elevated intracranial pressure and rapid expansion. Surgical intervention is needed only when visual disturbance, hypopituitarism or enlarging lesion is shown. Thus, we present a case of primary amenorrhea due to intrasella arachnoid cyst which was resected through the transsphenoidal approach.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

BACKGROUND: Video-assisted thoracic surgery (VATS) is being used as a therapeutic modality in many diseases in which thoracotomy has been used. We studied that the VATS can substitute the thoracotomy in benign esophageal disease. MATERIAL AND METHOD: Group I (n=18) underwent video-assisted thoracic surgery, and group II (n=19) thoracotomy. Group I includes 14 leiomyomas and 4 achalasias. Group II includes 16 leiomyomas and 3 achalasias. Operative technique is enucleation in the leiomyoma and modified Heller's myotomy in the achalasia. Analyzing factors of operation-efficacy are anesthetic time, operation time, hospital stay, chest tube drainage amount and chest tube removal day. The degree of the postoperative pain is assessed by the frequency of opioid analgesics injection. RESULT: There was no death in both groups. There were 5 complications in the group I and 2 in the group II. Prolonged pleural effusion and restenosis of achalasia occurred to 1 patient in each group. In the group I, there were 1 temporaty vocal cord palsy and 2 mucosal tear leading to thoracotomy. There were no differences in anesthesia time, operation time, hospital stay, total chest tube drainage amount, chest tube removal day and frequency of opioid analgesics injection. The amount of the chest tube drainage at POD 1 day was significantly lower in group I (155.6+/-77.8cc) than in group II (572.8+/-280.1cc) (p<0.05). CONCLUSION: The results of our data showed that video-assisted thoracic surgery for benign esophageal disease is as effective as thoracotomy and in addition, cosmetic effect is much better. We concluded VATS may be a substitute for thoracotomy in benign esophageal disease.

BACKGROUND: Sensitive skin is largely agreed to be a lay term used by individuals who have reduced tolerance to frequent or prolonged use of cosmetics and toiletries, with symptoms ranging from subjective neurosensory forms of discomfort such as stinging, burning, itching, tightness and smarting sensations to visible signs of irritation such as erythema and scaling. Although the concept of sensitive skin is intriguing to many dermatologists, the diagnosis is dependant on self-perceived symptoms. Models to define sensitive skin are not standardized, and the term sensitive skin can be misleading. OBJECTIVE: The purpose of this study was to evaluate difference of influence to skin barrier function between corrosive and non-corrosive agents in sensitive skin. METHODS: 0.1%, 0.25%, 0.5%, 2% solution of sodium lauryl sulfate (SLS) and 1%, 2.5%, 5%, 20% solution of nonanoic acid (NAA) were applied on volar forearm skin for 24 hours in healthy controls and self-perceived sensitive skin subjects without underlying problems. Clinical score, transepidermal water loss (TEWL), and erythema-index (E-index) were compared between healthy controls and the sensitive skin group. RESULTS: Clinical scores, TEWL values and E-indices showed a rising curve concentration for each irritant in a similar pattern. There were no significant differences in clinical score and TEWL value between non-sensitive and sensitive skin. In contrast, E-indices evaluated from sensitive skin subjects were much higher than those in a healthy controls. CONCLUSION: An elevated TEWL value indicates barrier impairment. An increase in the erythema parameter shows that cutaneous vascular reactions have an unspecifically exaggerated reaction to various irritants and this induces multifarious inflammatory reactions and vasodilation. Therefore, the results of this study suggest that sensitive skin without underlying disease is derived from cutaneous vascular hyperreactivity and various inflammatory reactions, rather than barrier impairment.

PURPOSE: We investigated the causative organism and its antibiotic susceptibility of community acquired urinary tract infection (UTI) in children at a secondary hospital to test the adequacy of the current guidelines. METHODS: Children diagnosed with UTI at the Department of Pediatrics, Kwandong University Myongji Hospital by pyuria and bacterial growth of greater than 1.0x10(5) CFU/mL on clean catch midstream urine from January 2005 to December 2008 were studied retrospectively. The epidemiologic data, causative organism, and the antibiotic susceptibility were analyzed. RESULTS: Sixty two children were diagnosed with sixty four cases of UTI's. Two bacteria were isolated in one case and thus data on 65 urine cultures were analyzed. The male:female ratio was 1.6:1 and 78.1% were less than 12 months of age. Escherichia coli was the predominant cause consisting of 53 cases (82.8%) of the cases. K. pneumoniae (5), Enterobacter (4), Enterococcus (1), beta-streptococcus (1), Diphtheroides (1) were isolated. The antibiotic resistance of E. coli were as follows; ampicillin 69.8%, cefotaxime 1.9%, gentamicin 15.1%, amikacin 0.0%, levofloxacin 1.9%, and trimethoprim/sulfamethoxazole 26.4%. Only one case of the E. coli was extended spectrum beta-lactamase (ESBL) positive. CONCLUSION: Compared to prior reports from other tertiary hospitals in Korea, E. coli was the predominant cause in childhood UTI and the rate of ESBL positivity was low. The antibiotic resistance was also different compared to prior reports. We conclude that a difference in the cause and antibiotic resistance of childhood UTI exists between centers and this should be taken into consideration when prescribing antibiotics for childhood UTIs.

We report a case of accidental epidural ephedrine injection. A 29-year-old male with left femoral artery occlusion was scheduled for thromboembolectomy. The operation was performed under epidural anesthesia. During the operation, ephedrine (30 mg/6 ml) was accidentally injected through epidural catheter instead of ropivacaine (45 mg/6 ml). Following the incident, we injected normal saline (10 ml) in the epidural space to dilute the solution. The patient had no complaint but blood pressure rose to 165/115 mmHg transiently. We observed the patient closely in recovery room and no further complication was found. In previous reports, various attempts have been tried to manage such incidents, but no definitive treatment for accidental injection is known. We present this case to remind the importance of confirming the drug everytime before injection.

PURPOSE: The objective of this study was to evaluate the initial fixation strength of press-fit technique compared with titanium and biodegradable interference screws in ACL reconstruction using bone-patellar tendon-bone grafts. MATERIALS AND METHODS: Fifty porcine lower limbs were used. The graft in the press-fit group was harvested with a hollow oscillating saw to obtain a consistent and complete circular shape and that in the interference screw group was obtained with a conventional oscillating saw. With preload of 20 N, the specimens underwent 250 loading cycles between 0-2 mm of displacement. Thereafter, the specimens were loaded to failure after restoration of the preload. RESULTS: During the cyclic loading, none of press-fit or interference screw fixations failed and there was no significant difference in maximum loads between the groups. In groups of press-fit fixation with diameter of bone plug being larger that that of the femoral tunnel by 1.4 mm, the ultimate failure load was comparable with that of the titanium or biodegradable interference screw groups. The complete circular shape and increased diameter of the bone plug seemed to contribute the strong initial fixation. CONCOUSION: Press-fit fixation technique provides a secure and consistent fixation strength comparable with the metal or biodegradable interference screws.
