Carbon monoxide is colorless, oolorless, tasteless and non-irritating gas produced by the incomplete combustion of carbonaceous rnaterial. It combines with hemoglobin and displaces oxygen because the affinity of hemoglobin for carbon monoxide is two hundred times greater than oxygen. Symptoma and signs of carbon monoxide poisoning include headache, nausea, vomiting, dizziness, collapse, unconsciousness, blindness, convulsion, coma and skin lesions. Recently we have observed seven patients with carbon monoxide poisoning who expressed cutaneous syrnptoms. In this work we investigated the pathogenesis of cutaneous manifestations of carbon monoxide poisoning through clinical, histologic and electronmicroscopic study. The results are summarized as follows: 1. Mental states of the patients were comatose in two, Semicomatcse in two, stuporous in two, and drowsy in one patient. In routine laboratory tests, we observed elevated blood sugar in six, elevated sorum creatinine phosphokinase in four and abnormal findings in urinalysis in all patients. 2. Cutaneous lesions were vesicobullae, plaque or swelling, erythema, gangrene and 'ulceration in order of frequency and located in the dependent areas in six caies. 3. Histopathologically, the sites of the bullae were subepidermal in four cases and intraepidermal in. one case and there was one case with ulceration. 4. In electronmicroscopic findings, secretory and ductal cells showed degenerative

Lipomas are common soft tissue that are usually located in the subcutaneous tissue. And intramuscular lipomas commonly arise in the upper and lower extremities, where they usually involve the large muscles. Intramuscular lipoma, also referred to as an infiltrating lipoma, is an unusual benign slow growing tumor composed of mature fat cell interdigitating with skeletal muscle. However, intramuscular lipomas are exceedingly rare in the face. We have been experienced a case intramuscular lipoma that located in the malar area. Because of the rarity of these tumors and their propensity to recur without adequate surgery, the case report is presented here. Achievement of surgical margin is essential as the recurrent rate may be as high as 15% to 62.5% without complete excision.

This study was to evaluate the clinical usefulness of 99m Tc-MDP bone scintigraphy for assessing vascular ingrowth into the ocular implants after enucleation and evisceration. Twenty four patients(M:F=7:17, mean age:36), with a coralline hydroxyapatite after uncomplicated enucleation or evisceration surgery were studied. Uptake ratio was also calculated by measuring the implants activity(H)and contralateral orbit activity(N). Grading score and uptake ratio were compared with clinical outcome of vascularization. Additionally, we also analyzed the vascularization status as time lapse between primary surgery and scintigraphic study and surgical methods. The degree of grade and uptake ratio were inversely correlated with vascular ingrowth. Higher than grade 2 or greater than 1.56 in H/N ratio seemed to be an indicator for better prognosis. 99m Tc-MDP bone scintigraphy can be a useful method to evaluate the vascularized status of implants. Adequate time for 99m Tc-MDP bone scintigraphy after enucleation and evisceration was 11~20 weeks.

PURPOSE: To report a case of unilateral oculomotor nerve palsy with synergistic divergence. METHODS: A 30-year-old man presented with outward and downward deviation of the right eye, ptosis of both eyes, and abnormal eyeball movement on left gaze since birth. His corrected visual acuity was 0.1 in the right eye and 0.7 in the left eye, indicating amblyopia in the right eye. Both eyes had high myopia of 10 diopter. In the primary position, there was a right exotropia of 70 prism diopter (PD) and hypotropia of 20 PD at both near and distance, accompanying ptosis of both eyes. Ocular motility examination revealed the absence of adduction in the right eye and the supraduction difficulties in both eyes, with a simultaneous abduction of both eyes on levoversion. The electrooculographic record of the patient showed that the movement of the right eye is always opposite to that of the left eye on levoversion. We performed lateral rectus recession 10 mm, medial rectus tucking 8 mm, and inferior rectus recession 3 mm in the right eye. Postoperatively, exotropia and hypotropia was reduced to each 10 PD and 4 PD, but there was no improvement of synergistic divergence. RESULTS: This case is thought to be a synergistic divergence combined with the oculomotor nerve palsy. The horizontal muscle surgery reduced the exotropia but did not improve the synergistic divergence in this patient.

PURPOSE: We assessed the feasibility and efficacy of a laparoscopic approach in surgically managing various conditions of the acute abdomen. METHODS: This report presents preliminary data from our ongoing prospective study. Sixty patients underwent a diagnostic or a therapeutic laparoscopy for acute or subacute abdominal conditions between July 1997 and September 1998. RESULTS: Conditions were classified into trauma (n=8), peritonitis (n=41), and obstruction (n=11). Trauma included 5 blunt (2 small bowel perforations, 1 spleen rupture, 2 mesenteric ruptures) and 3 stab injuries. Peritonitis included 23 duodenal ulcer perforations, 10 acute cholecytitis/empyema, 3 colon perforations, 1 tuberculous peritonitis, 1 ectopic pregnancy, 1 ruptured corpus luteum, 1 appendicitis, and 1 ruptured liver abscess. Obstruction included 5 intussusceptions (4 Children, 1 adult), 2 intestinal adhesions; and 4 congenital hypertropic pyloric stenoses. Among the 54 cases of therapeutic laparoscopy, 9 cases were converted during the procedure (conversion rate: 16.7%). There were 2 intraoperative (bowel perforation) and 4 postoperative (1 subphrenic abscess, 1 incomplete adhesiolysis, 1 port site hernia, 1 port-site seroma) complications. CONCLUSION: Our preliminary data may justify further clinical study to clarify the role of laparoscopy in managing acute or subacute abdominal conditions.

BACKGROUND AND OBJECTIVES: One of problems for the management of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) is the difficulty of determining the affected ear using Ewald's second law. The purpose of this study is to develop the new "Bow and Lean Test (BLT)" to determine easily the affected ear of HSC-BPPV and evaluate its efficiency. MATERIALS AND METHOD: We compared the efficiency between the classical method and BLT in 26 patients with HSC-BPPV. The classical method is based on Ewald??s second law comparing the intensity of nystagmus or symptoms in head roll test. BLT is based on the direction of both "bowing nystagmus" and "leaning nystagmus" at head's bowing and leaning state on sitting position. The affected ear is the same direction of bowing nystagmus in canalolithiasis and the same direction of leaning nystagmus in cupulolithiasis. RESULTS: In 26 patents (15 canalolithiasis, 11 cupulolithiasis), 3 (11.5%) patients did not show a prominent affected ear in the classical method, and 7 (26.9%) patients showed the different affected ear between two methods. All 10 patients were successfully treated with just one trial of barbecue rotation based on the affected ear in BLT. Three patients did not show any bowing or leaning nystagmus. The side with canal paresis in all 4 patients, who showed significant canal paresis in bithermal caloric tests, was equal to the affected ear based on BLT. CONCLUSION: "Bow and Lean Test" (also called "Choung's test") is a new method which can easily determine the affected ear of HC-BPPV.
