A nineteen year-old boy with progressive enlargement of the joints and distal extremities, clubbing, coarse facial features and hyperhidrosis was investigated. In physical examination, thickening of the scalp with furrowing (cutis verticis gyrata) and greasy thickening of skin (pachyderma) was prominent. His endocrine profile was normal. Radiological studies demonstrated bilateral symmetrical periosteal new bone formation with acroosteolysis and incidental microadenoma of pituitay gland. After extensive investigation to exclude systemic and endocrine causes, the patient was diagnosed as pachydermoperiostosis (PDP). PDP is a rare syndrome manifested clinically by finger clubbing, extremity enlargement, hypertrophic skin changes, and periosteal bone formation. The pathogenesis of the disorder has not been clarified though few endocrine abnormalities were seen. To aware of these clinical phenotype would help to differentiate PDP from acromegaly.

BACKGROUND: During laryngoscopy, force applied to the soft tissue are assumed to cause circulatory response. The aim of the study was to evaluate this circulatory response and to analyze the relationship between the intensity of the force and the magnitude of the associated circulatory responses. METHODS: Sixty-three healthy patients, aged 17 to 29 years, were randomly allocated to one of three groups according to the three different subjective forces applied intentionally. Subjects in group 1 received minimal force enough to stimulate circulatory response, but not enough to expose the glottis. Group 2 received the optimal force necessary to expose the glottic opening. Group 3 received excessive force to expose the glottic opening. The axial forces of the laryngoscope handle with a Macintosh blade were measured during a ten-second laryngoscopy, and peak force, mean force, and area under the curve were calculated. Then, arterial pressure and heart rate were recorded after the laryngoscopy at 30 seconds intervals for 3 minutes. The data was compared among groups and with the baseline post-induction values. RESULTS: No significant difference was found in heart rate and blood pressure at each interval among the three groups, with increasing arterial pressure and heart rate after the laryngoscopy. Blood pressure and heart rate were maintained high, being progressively higher in the groups receiving a higher force. CONCLUSIONS: We conclude that little association was found between the force and the magnitude of circulatory response although higher forces cause longer circulatory responses.

Familial adenomatous polyposis (FAP) is an hereditary autosomal dominant disease characterized by development of hundreds to thousands of adenomatous polyps in the colon and rectum. The common symptoms are bloody stool, diarrhea, and abdominal pain. The average age at onset of symptoms is 33 years. Because of inevitable progression to malignancy, it is necessary to remove the entire colonic and rectal mucosa. Current surgical options are total proctocolectomy with permanent ileostomy, trans-abdominal colectomy with ileorectal anastomosis (IRA), and restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Recently IPAA can give optimum control of colorectal polyposis in FAP patients with an acceptable incidence of postoperative complications and satisfactory functional results. We experienced one case of FAP who had malignacy in the remained rectum after subtotal colectomy. IPAA was done and the result was satisfactory.

PURPOSE: To investigate the localization and functional lateralization of the supplementary motor area (SMA) in motor activation tests in comparison to that of the primary motor area. MATERIALS AND METHODS: Seven healthy volunteers obtained echoplanar imaging blood oxygen level dependent technique. This study was carried on 1.5T Siemens Magneton Vision system with the standard head coil. Parameters of EPI were followed as ; TR/TE; 1.0/66.0 msec. flip angle : 90degree, field of view : 22cmx22cm, matrix : 128x128, slice number/slice thickness/gap : 10/4mm/0.8mm with fat suppression technique. Motor task as finger opposition in each hand consisted of 3 sets of alternative rest and activation periods. Postprocessing were done on Stimulate 5.0 by using cross-correlation statistics. To compare the functional lateralization of the SMA in the right and left hand tests, each examination was evaluation for the percent change of signal intensity and the number of activated voxels both in the SMA and in the primary motor area. Hemispheric asymmetry was defined as difference of summation of the activated yokels between each hemisphere. RESULTS: Percent change of signal intensity in the SMA (2.49-3.06%) is lower than that of primary motor area(4.4-7.23%). Percent change of signal intensity including activated voxels were observed almost equally in the right and left SMA. As for summation of activated voxels primary motor area had significant difference between each hemisphere but not did the SMA. CONCLUSION: Preferred contralateral dominant hemisphere and hemispheric asymmetry were detected in the primary motor area but not in the SMA.

The Meckel's cave is a dural recess containing trigeminal nerve and ganglion, extending from the posterior fossa into the middle cranial fossa. Using MRI, internal architecture in the Meckel's cave can be discernible, even a small nodule within it can be detected. There are a wide spectrum of disease process occurring in and or in the vicinity of the Meckel's cave. Disease can be classified into pathology of the trigeminal nerve proper, within the trigeminal cistern and outside the trigeminmal cistern. These classification depending on the location will aid in interpretation of pathology of Meckel's cave. We will demonstrate the MR anatomy and various pathologies of the Meckel's cave.

PURPOSE: To see the stability and error in the diffusion-weighted magnetic resonance (MR) imaging technique in the experimental models and to observe the signal intensities in the early cerebral lesions of the animal models. MATERIALS AND METHODS: Diffusion coefficients of acetone and distilled water were measured by diffusion-weighted MR image and were compared with actual values. Differentiation of diffusion from perfusion were done at the resin flow phantom. The signal intensities caused by early parenchymal changes were measured in normal, hypovolemic, and embolic, and dead animal models by using diffusion-weighted image and compared with pathoIogic finding and vital staining. RESULTS: Diffusion coefficients of acetone and distilled water were 4.48 x 10-3 and 2.72 x 10-3 which were very close to the actual values. Diffusion-weighted MR image obtained at flow phantom was not affected by flow (perfusion) at the 100-400 of b-factor range. Animal study done at that b-factor range revealed a significant signal difference between the left and right sides only at the embolic model induced by polyvinyl alchol particles (p<0.05). These changes were not detected in microscopic finding but could be identified in vital staining. CONCLUSION: Diffusion-weighted MR image can be used to detect early parenchymal change when the appropriate b-factor range was applied.

The complications following the use of laryngeal mask(LM) are usually mild and cause clinical problems rarely. However, as the use of LM increases, it seems important to know the common injuries, symptoms, and factors relevant to complications from its use. We investigated prospectively the influence of age, sex, height, weight, duration of LM placement, presence of blood tinged on LM and coughing on LM placement, use of anticholinergics, anticholinesterase, and opioid on the mucosal injuries and patient symptoms in 97 healthy adult patients undergoing elective surgery by the indirect laryngoscopy and questionnaire 8~24 hours after surgery. The upper airway symptoms were throat discomfort(22.7%), and sore throat(10.3%). The findings of mucosal injuries were erythema(27%), edema(5%), and petechial hematoma(2%). The mucosal injuries were centered around the pharynx and the epiglottis(63.6% of total mucosal injuries), and 17 of 21 patients who were observed to have mucosal injuries complained upper airway symptoms. These resuts suggest that the pharynx and epiglottis are most vulnerable to injuries and most common sites causing upper airway symptoms from the LM placement. Vocal cord erythema was found in 8.2% of patients, which was seemed to be due to the grates of the LM aperture. The severity of the mucosal injuries was correlated to the severity of upper airway symptoms(P < 0.05, r=0.464). Male sex, presence of blood on LM, and the longer duration of LM placement were associated with a relatively high incidence of mucosal injuries, and the longer duration of LM placement with that of upper airway symptoms(P < 0.05). After above variables were controlled for, presence of blood on LM was a precipitating factor in mucosal injuries and the longer duration of LM placement was precipitating factor in symptoms(P < 0.05). We failed to find a significant correlation of duration of LM placement with the severity of mucosal injuries or symptoms.

BACKGROUND/AIMS: Despite recent advances in liver surgery, complication and mortality rate in hepatectomy are still high compared to other abdominal surgeries. Intraoperative stress such as bleeding, vascular occlusion, excessive mobilization and prolonged operation time is the most important factor in postoperative complications. Anterior approach avoiding hepatic mobilization and vascular occlusion in right hepatic lobectomy is a useful method for decreasing intraoperative stress. We investigated the effectiveness of anterior approach in right hepatic lobectomy. METHODS: We studied 33 cases of right hepatic lobectomy for malignant tumor between January 1993 and June1997. Thre were 13 cases of Anterior approach (group A) and 20 cases of classic right hepatic lobectomy (group B). We analyzed liver function test, arterial ketone body ratio(AKBR), operation time, blood transfusion during operation, hospital stay, and postoperative complications. RESULTS: Total bilirubin levels at first and seventh postoperative days were 2.1+/-0.6mg/dl, 0.9+/-0.2mg/dl in group A and 2.7+/-1.3mg/dl, 1.0+/-0.3mg/dl in group B. AST were 189+/-65.3 IU/L, 43+/-13.5 IU/L in group A and 325+/-67.8 IU/L, 51+/-18.2 IU/L in group B. ALT were 169+/-30.5 IU/L, 52+/-17.4 IU/L in group A and 295+/-70.3 IU/L, 52+/-16.6 IU/L in group B. AKBR at intraoperative and immediate postoperative period were 0.58+/-0.06, 0.62+/-0.03 in group A and 0.38+/-0.04, 0.40+/-0.08 in group B. Neither operation time (in group A : 380.5+/-61.1 minutes, in group B : 342.9+/-54.8 minutes), transfusion volume during operation (group A : 1222+/-802cc, group B : 1410+/-476cc), nor hospital stay (group A : 22.8+/-3.5 days, group B : 19.1+/-1.4 days) were different between the two groups. Complication rate was lower in group A compared to that of group B (30.8% vs. 40.0%). There was 1 mortality in group B and no mortality in group A. CONCLUSIONS: It is suggested that right hepatic lobectomy through the anterior approach is a useful surgical procedure to reduce intraoperative surgical stress and postoperative complications.
