OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.

Neonatal acute suppurative parotitis is rare. Staphylococcus aureus is the most common pathogen and antibiotic treatment is the first line therapy. Here, we report a case of acute suppurative parotitis caused by Escherichia coli in a 7­day­old male with febrile sensation, parotid swelling, and purulent discharge from the Stensen duct who was treated successfully with intravenous antibiotics. To the best of our knowledge, this is the first case of neonatal suppurative parotitis caused by E. coli in Korea.

BACKGROUND: The start-up behavior of syringe and syringe pump is known to be one of the causes of inaccurate intravenous infusion. This study evaluated the method of priming the infusion system (PRIMING), and its impact on the target-controlled infusion (TCI) of two remifentanil diluents. METHODS: PRIMING was performed using an evacuation of 2.0 ml to the atmosphere prior to TCI. Forty-eight TCI, using 50 microg/ml (Remi50) or 20 microg/ml (Remi20) of diluents, were performed targeting 4.0 ng/ml of effect-site concentration (Ceff), with PRIMING or not. The gravimetrical measurements of the delivered infusates reproduced actual Ceff. The bolus amount and time to reach 95% target were compared. RESULTS: Without PRIMING, Remi50 infused less bolus (43 +/- 23 %) than Remi20 (19 +/- 9 %) (P = 0.003), and showed more delayed increase of Ceff (11.2 +/- 4.0 min) than Remi20 (7.4 +/- 0.4 min) (P = 0.028). However, PRIMING significantly decreased the deficit of the bolus (2 +/- 1%), as well as the delay of the increase of Ceff in Remi50 (1.2 +/- 0.2 min) (both P < 0.001). In addition, with PRIMING, the start-up bolus showed minimal difference to the nominal bolus (1 and 2%), and Ceff were increased to 4.0 +/- 0.1 ng/ml at the expected time of peak effect, irrespective of the diluents. CONCLUSIONS: Proper operation of the syringe pump used in the priming of the syringe may be helpful in reduction of the inaccuracy of TCI, particularly during the early phase of infusion, or the infusion of a more concentrated diluent.

Although technological advances and clinical studies on stem cells have been increasingly reported in stroke, research targeting hemorrhagic stroke is still lacking compared to that targeting ischemic stroke. Studies on hemorrhagic stroke are also being conducted, mainly in the USA and China. However, little research has been conducted in Korea. In reality, stem cell research or treatment is unfamiliar to many domestic neurosurgeons. Nevertheless, given the increased interest in regenerative medicine and the increase of life expectancy, attention should be paid to this topic. In this paper, we summarized pre-clinical rodent studies and clinical trials using stem cells for hemorrhagic stroke. In addition, we discussed results of domestic investigations and future perspectives on stem cell research for a better understanding.

In human, Human Papilloma Virus(HPV) is associated with benign squamous tumors in a variety of body sites. But the relationship between HPV infection and malignant epithelial lesions is not clear. Esophageal squamous papilloma is relatively rare tumor but it is reported with increasing frequency recently. We reviewed twenty six patients of esophageal papilloma diagnosed by endoscopic biopsy from 1990 to 1994. The results are as follows; The peak age is fifth decade, men and women ratio is 1: 1.2. Most papillomas located in distal esophagus and have no specific symptoms related to papilloma. All case are sessile form and no malignant change in follow up endoscopy.

BACKGROUND: Video-assisted sympathicotomy is a safe and effective method for the treatment of essential hyperhidrosis with immediate symptomatic improvement. However, this is offset by the occurrence of a high rate of side-effects, such as embarrassing compensatory hyperhidrosis. Therefore, by comparing and assessing the relationship between temperature change measured by DITI (digital infrared thermographic imaging) and clinical results according to the level and extent of sympathicotomy in essential hyperhidrosis. we tried to obtain a more precisely and objectively, the distribution and degree of compensatory sweating by DITI and also for ascertaining the clinical usefulness. MATERIAL AND METHOD: From January 2000 to June 2002, the thoracoscopic sympathicotomy was performed in 28 patients suffering from essential hyperhidrosis in Dept. of Thoracic and Cardiovascular Surgery, Wonkwang University Hospital. The patients were divided into four groups, Group I: patients having undergone T2 sympathicotomy, Group II: patients having undergone T3 sympathicotomy, Group III: patients having undergone T3,4 sympathicotomy, and Group IV: patients having undergone T2,3,4 sympathicotomy. The parameters were composed of the satisfaction rate of treatment, the degree of compensatory and plantar sweating, and temperature changes of entire body measured by DITI RESULT: There was no difference in age and follow-up period among the groups. All of the treated patients obtained satisfactory alleviation of essential hyperhidrosis in immediate postoperative period. However, the rate of long-term satisfaction were 85.8%, 85.8%, 42.9%, and 28.6% in group I, II, III, and IV (p<0.05). More than embarrassing compensatory sweating was present in 14.2%, 14.2%, 57.1%, 71.4% in group I, II, III, and IV (p<0.05) In regard to plantar sweating, decrease in sweating was expressed in each of four groups, but was not significant between groups. An apparent increase of temperature measured by DITI indicated sufficient denervation and predicted long-lasting relief of essential hyperhidrosis and also decrease in temperature of trunk and lower extremity by DITI had correlated well with postoperative satisfaction, and also postoperative compensatory sweating. CONCLUSION: We suggested that the incidence and degree of compensatory sweating was closely related to the site and the extent of thoracic sympathicotomy. Resection of the lower interganglionic neural fiber of the second thoracic sympathetic ganglion on the third rib is the most practical and minimally invasive treatment than other surgical methods. We were also to anticipated the distribution and degree of compensatory sweating by DITI precisely and objectively and for ascertaining the clinical usefulness.

PURPOSE: Inguino-femoral hernias in women are less common than that in a man, and we have had limited experience for hernia repair in women. The purpose of this study was to evaluate the characteristics of inguino-femoral hernias in females and to establish the choice of specific treatment for inguino-femoral hernia in females. METHODS: This retrospective study was based on the medical records of 566 patients who underwent 657 cases of herniorrhaphies for treating inguino-femoral hernia in adult females from January 1998 to June 2006. We evaluated the incidence of hernia, the operative technique and the length of the operation, the complications and the postoperative recurrence rate. The operative findings and median time to reoperation for a recurrent hernia were also evaluated. RESULTS: During the 8.5-year period, we performed 2,931 herniorrhaphies in 2,274 patients. Of these, 657 herniorrhaphies were done in females (22.4%). The types of hernia in females were indirect inguinal hernia (67.3%), direct inguinal hernia (10.2%), the pantaloon type (10%) and femoral hernia (14.9%). Femoral hernia was more frequent in females (14.9%) compared to males (3.5%) (P<0.001). The overall rate of reoperation due to incarceration in the females was higher (2.5%) than that in the men (1.1%)(P<0.001). Femoral hernias in females was found at reoperation in 39.7% compared with 17.2% in the males (P<0.001). CONCLUSION: The incidence of inguino-femoral hernia in females was higher than the results of most published studies and the reoperation rate was higher in females. The increased frequency of femoral hernia at reoperation in females suggests avoiding injuries to the posterior wall of the inguinal canal and the need for exploration of the femoral canal at the time of the primary operation.

STUDY DESIGN: A retrograde study of metal failures at thoracolumbar spinal fractures fixed using pedicle screws. OBJECTIVES: The predictability and usefulness of the McCormack's classifications for metal failures was compared with Magerl's classifications. SUMMARY OF LITERATURE REVIEW: The load sharing classification was introduced to predict metal failure after short-segmental pedicle screw fixation by McCormack. However, its reliability is uncertain. MATERIALS AND METHODS: From July 2000 to July 2003, this study examined the plain radiographs and CT images of 31 out of 46 patients who underwent posterior stabilization using pedicle screws for thoracolumbar fractures and could be followed up at least 1 year. Fractures were classified utilizing Denis's, Magerl's, and McCormack's systems. RESULTS: As a result of analysis of relation between metal failure and classification system by Magerl or McCormack, there was no significant difference in its distribution. There was no correlation between the fixation range and metal failures in type C3 fractures, but there was a correlation between short fixation and metal failures in rotational burst fractures in short fixation. CONCLUSIONS: In order to prevent metal failures after fixing thoracolumbar spinal fractures by pedicle screws, the stability should be evaluated using Magerl's classification and McCormack's total score. In addition, in cases of type C3 fractures according to the Magerl's classification, reconstructions should be carried out with a long segment fixation or anterior supporting bone grafts, particularly when McCormack's total score is greater than 7.

PURPOSE:Carotid endarterectomy may benefit patients with bilateral carotid stenosis by improving cerebrovascular hemodynamics of ipsilateral as well as contralateral cerebral hemispheres. We investigated cerebrovascular hemodynamics after carotid endarterectomy in patients with contralateral carotid occlusion by acetazolamide stress brain SPECT. MATERIALS AND METHODS: Subjects were 14 symptomatic patients (all men, mean age 66 yrs) with carotid stenosis (> 50%) with contralateral carotid occlusion. Acetazolamide stress Tc-99m ECD brain SPECTs were performed within 2 weeks before and after carotid endarterectomy using one day protocol. Cerebral blood flow (CBF) and cerebrovascular reserve (CVR) were assessed visually. In 12 patients, correlation between the patency of proximal anterior cerebral or anterior communicating arteries (A1/A-comm) and the improvement of CBF or CVR after endarterectomy was assessed. RESULTS: Preoperative SPECT showed reduced CBF in 2 ipsilateral and 10 contralateral hemispheres. CVR was reduced in 4 ipsilateral and 9 contralateral hemispheres. Of 12 hemispheres with reduced CBF, 2 hemispheres (16.7%) showed improvement of CBF after endarterectomy. However, reduced CVR was improved in all 4 ipsilateral and 7 of 9 (78%) of contralateral hemispheres after endarterectomy. Three of 4 with stenotic A1/A-comm and 4 of 8 with patent A1/A-comm had reduced contralateral CVR. Reduced contralateral CVR improved in all 3 patients with stenotic A1/A-comm and 3 of 4 with patent A1/A-comm. CONCLUSION: Acetazolamide stress brain SPECT demonstrated improvement of compromised cerebrovascular reserve in not only ipsilateral but also contralateral hemispheres of patients with contralateral carotid occlusion after carotid endarterectomy, and may, therefore, be useful for evaluating cerebral blood flow and cerebrovascular reserve after carotid endarterectomy.
