Orthopaedic wire has been used widely as a good internal fixator in cases of fracture, the ligament reconstruction, and for the stabilization of cervical spine. But if it is used inappropriately, a wire can be easy to fail by elongation, untwisting, or breakage. Among them, the most common failure of wire is breakage. To clarify the mechanism and the causes of wire failure, the authors analysed serial roentgenograms and scanning electronmicroscopic findings of broken wire in total 13 cases, which were experienced at the department of orthopaedic surgery, St. Mary's Hospital, Catholic University Medical College From January 1981 to December 1987. The results obtained were as follows :1. The mechanism of wire failure were classified into the 4 types ; minor continual flexing motion in 6 cases, repeated minor back and forth torsion in 1 case, tension failure in 2 cases and combined type in 4 cass. 2. The causes of wire failure were in appropriate use and inadequte application, a lack of s ufficient mechanical strength, micromotion due to inadequate postoperative imm obilization, early mobilization before tissue healing as well as certain injuries to the wire during handling in operation.

The fifty gastrointestinal polyps, which were removed endoscopically frorn 47 patients at the Seoul National Univeraity. Hospital from January, 1978 to September, 1983, were reviewed with regard to the clinical and pathological features. The observed data are as follows; 1) Fifty polyps were reoved from 10 patients with gastric polyps and 37 patients with colonic polyps. Out of 37 patients 26 were male and 21 female, the sex ratio being 1.2: 1. 2) The gastric polyps were located in the body and antrum and 90 per cent of the colonic polyps were found in the left colon, especially in the rectosigmoid colon. 3) Out of the 10 gastric ployps snared, 8 could be retrivevd, 2 being lost. The histological examination showed that 3 were hyperplastic polyps, 2 gastritis verrucosa, 1 inflammatory polyp and the remaining 1 revealed intramucosel carcinoma with borderline epithelium. 4) Fourty polypectomies were performed in 37 patients with colonic polyps. Histological examination revealed that 24(60%) were adenomatous polyps, 9(22.5%) retention polyp, 4 (10.0%) inflammatory polyp and 3(7. 5%) Peutz-Jegher's poIyps. Among the adenomatous polys, 4 cases were complicated with focal adenocarcinoma. 5) Except the 2 cases of post-polypectomy bleeding, no other complication was encountered. The one case of hemorrhage after gastric polypectomy was treated with transfusion of 2 pints of whole blood, and the other case after colonic polypectomy required exploratory laparotomy because of inability of bleeding control by electrocoagulation.

Artichia with papular lesions is a rare congenit,al disease characteriezed by the association of alopecia and papular lesions. We report a case of atrichia with papular lesions in 12-year-old. Alopecia of the scalp and eye brows were present at birth. Nurnerous papular lesions are presentation the trunk, buttock and inguinal area. The histopathologic iinding of a papular lesion showed ker till-filled cyst, and eruptive vellous hair cyst. The patient showed reticulat.ed hyperpigmentation on the hands and feet in addition to the characteristic feature of atriclia with papular lesions.

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

Morquio's syndrome is a very rare disease, which is characterized by dwarfism, flattening of the vertebral body, marked spinal kyphosis, widespread affection of the epiphyses and normal intelligence. The authors experienced a case of Morquio's syndrome with typical clinical and radiological findings. The patient underwent bilateral supracondylar varus osteotomies for severe genu valgum deformities.

We reviewed thrity-one cases of unstable tibial fractures treated with Ilizarov method from January 1991 to December 1992. We attained satisfactory bony union in all cases without bone graft(Average time 19.2 weeks). There were numbers of complications, but its were soluble and careful management & numbers of minor surgery were needed to prevent & solve such complications. Post-op immediate weight bearing and ROM exercise were possible and showed no difficulty in getting mainteance of reduction & fracture healing, and serious joint ankylosis was not developed. In conclusions, Ilizarov method is an excellent treatment in getting reduction, maintenance of reduction, early ambulation and fracture healing in the cases of unstable tibia fractures.

The authors analysed 261 cases of mycoplasmal pneumonia in children who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis in 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinini titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (P>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. the mean duration of admission by the type of pneumonia was lobar, lobar (10.71+/-3.40), interstitial (8.78+/-2.14), and bronchopneumonia (8.83+/-2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.
