Erdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis with multi-organ involvement. Bones, cardiovascular system, central nervous system, kidney, skin and many different organs can be involved but laryngeal involvement has not been reported in literatures. The diagnosis of ECD was based on clinical manifestations and immunohistochemical findings including CD68(+), CD1a(-) and S100(-). Currently, Interferon-a is the most extensively studied agent in the treatment of ECD and serves as the 1st line of treatment. Surgical resection of involved lesions can be tried but it leads to temporary improvement. A 60-year-old man visited with respiratory symptoms because of ECD with laryngeal involvement. We resected the obstructive lesion to relieve the symptoms. Tissue biopsy gave a diagnosis of ECD. As it is rare to encounter ECD involving the larynx, we report this case with a review of literatures.

The gastrointestinal polyp is a premalignant lesion in varying degree. According to the size, the pathology and the location of polyps, it should be removed. Polyps in the gastrointestinal tract can be removed by surgical excision, electrosurgery, cryotherapy, regional radiotherapy and laser therapy with some limitations. Considerable advance in therapeutic endoscopy as well as in diagnostic endoscopy along with newly developed instruments has now made it possible to excise gastrointestinal polyps by means of high frequency generator. We have underwent endoscopic polypectomy, strip biopsy and "O" ring ligation on gastric polyps in 112 patients who visited in this hospital from July l988 to January 1994, and the clinical characteristics including histopathology has been evaluated. Removed polyps were variable in size from less than 0.5 cm up to 4cm. Finally, we concluded that endoscopic polypectomy is a safe and relativly simple procedure and postpolypectomy complication can be considerably reduced by conservative antiulcer therapy.

Effect of acetylcholine(ACh) and McN-A-343 on porcine coronary artery and rabbit thoracic aorta were investigated in isolated preparations with or without intact endothelium. In the porcine coronary artery, ACh produced concentration dependent contraction which was greater in rings without the endothelium than in intact endothelial rings, but McN-A-343 did not alter the basel tension in both tissues. ACh relaxed contraction induced by 5-hydroxytryptamine(5-HT) in only intact endothelial rings, while NcN-A-343 inhibited the 5-HT induced tension in both preparations dose dependently. Carbachol elicited a prominent contraction in both tissues. The carbacol-induced tension was markedly inhibited by McN-A-343 in either rings with or without endothelium, while ACh contracted further the tension. ACh and McN-A-343 did not after the KCi induced tension, but clearly potentiated the contraction induced by Bay K 8644 in intact endothelial rings. In rabbit thoracic aorta, ACh elicited contraction in a concentration-dependent fashion which was potentiated by removal of endothelium, but McN-A-343 did not affect the basal tension of both rings. ACh inhibited the 5-HT-induced contraction in only intact endothelial ring, but McN-A-343 did not change the contraction of both rings. Conclusively, ACh produces endothelium-dependent relaxation in both arteries, while McN-A-343 elevated endothelium-independent inhibition to 5-HT or carbachol-induced tension.

PURPOSE: We tried to understand the effects of the derotational closing wedge Akin osteotomy during the operation for the hallux valgus with pronation of great toe. MATERIALS AND METHODS: Eighty five patients who had undergone Akin osteotomy among the eighty seven patients who had been treated with Scarf osteotomy with hallux valgus were included in this study. Derotational supination was added on the medial closing wedge Akin osteotomy at the base of proximal phalanx and it was secured with K-wire, headless screw or staple. We measured and analyzed pre- and post-operative hallux primus valgus angle and hallux pronational rotatory angle. RESULTS: The hallux primus valgus angle improved an average of 14+/-2.98 degrees to -1+/-1.68 degrees with the hallux pronational rotatory angle respectively from 24.8+/-7.64 degrees to 4.7+/-4.22 degrees. CONCLUSIONS: After the metatarsal osteotomy for the treatment of the hallux valgus with the pronation of great toe, derotational closing wedge Akin osteotomy can give us a belief that it can correct the hallux primus valgus angle and hallux pronational rotatory angle also and it can be a helpful method for minimizing the recurrence rate of the hallux valgus deformity.

Symphysis pubis separation is an uncommon but not rare complication of delivery. Characteristic symptoms of symphyseal separation include suprapubic pain and tenderness which radiate to the back or legs, difficult ambulation, and bladder dysfunction. Clinical history, presenting symptoms, and response to therapy are sufficient to make the diagnosis, although radiographic documentation of symphyseal separation by x-ray or ultrasound are frequently used to confirm the diagnosis. The underlying etiology of symptomatic symphyseal separation has not been fully elucidated. Associations with macrosomia, pathological joint loosening, and increased force placed on the pelvic ring have been suggested as possible etiologies. Conservative therapy, including bed rest, pelvic binders, ambulation devices, and mild analgesics usually result in complete recovery within 4-16 weeks. Our experience of three cases of peripartum symphysis pubis separation delivered from 1998 to 1999 were reviewed with related articles.

We have analysed 111 cases of subdural hygroma that were development after various neurosurgical conditions including head injuries. The results were summarized as follows. 1) The peak incidence was the age of 50's and occured most frequently in male. 2) Causes were head injuries(91 cases), traumatic intracranial hematoma removal(10 cases), operation for intracranial aneurysms(4 cases), hypertensive intracerebral hemorrhage evacuation(2 cases), ventriculoperitoneal shunt(2 cases), brian tumor removal(1 cases), arachnoid cyst excision(1 cases), and cerebral infarction(1 cases). 3) Acute subdural hematoma was most often associated with complex subdural hygrom. 4) Clinical manifestations were headache, altered mental state, disorientation, nausea in order. 5) Operation were underwent in 27 cases and surgical complications were reaccumulation and pneumocephalus in order. 6) Mortality rate was 6.3%. 7) The prognois of the simple hygroma was very good, but the complex was not.

BACKGROUND: We purposed to systemically review studies investigating the prophylactic effect of both pharmacological and non-pharmacological modalities against rocuronium induced withdrawal movement (RIWM) in the Korean population. METHODS: Literature search was performed using MEDLINE, EMBASE, CENTRAL, Koreamed, KMBASE, KISS and RISS up to March 2014. Randomized controlled trials (RCTs) comparing pharmacological and non-pharmacological interventions with placebo aimed for the Korean population were included. Outcome measures were the incidence and severity of RIWM. We conducted subgroup analyses according to each intervention method. RESULTS: Data were analyzed from 41 RCTs totaling 4,742 subjects. The overall incidence of RIWM was about 80% (range 56-100%). Incidence and severity of RIWM were significantly reduced with lidocaine (risk ratio [RR] 0.60, 95% CI 0.49-0.74; standardized mean difference [SMD] -0.74, 95% CI -1.05 to -0.44), opioids (RR 0.28, 95% CI 0.18-0.44; SMD -1.71, 95% CI -2.09 to -1.34) and hypnotics (RR 0.36, 95% CI 0.25-0.52; SMD -2.20, 95% CI -2.62 to -1.79). Regardless of tourniquet use, lidocaine showed a prophylactic effect against incidence and severity of RIWM: tourniquet (RR 0.36, 95% CI 0.21-0.62; SMD -1.51, 95% CI -2.15 to -0.86); non-tourniquet (RR 0.58, 95% CI 0.47-0.71; SMD -0.74, 95% CI -1.05 to -0.44). Dilution and slow injection of rocuronium decreased incidence and severity of RIWM: dilution (RR 0.47, 95% CI 0.39-0.56; SMD -1.64, 95% CI -2.47 to -0.81); slow injection (RR 0.34, 95% CI 0.17-0.70; SMD -2.13, 95% CI -2.74 to -1.51). CONCLUSIONS: The greater part of pharmacological and non-pharmacological interventions showed prophylactic effect against the incidence and severity of RIWM in the Korean population.
