The Ilizarov technique for gradual distraction osteogenesis was developed in the 1950s. A correctly performed osteotomy is essential to the success of distraction osteogenesis and prepares for limb lengthening. Between Sept. of 1991 and 1994, thirty-four patients were treated by Ilizarov technique at St. Benedict Hosp. and Gang-Dong Hosp.. And then assigned to two separate groups : a corticotomy group (group A) and osteotomy group (group B; osteotomy with Gigli saw or osteotomy with multiple drill holes and osteotome). The regenerate segments were evaluated weekly for the first six weeks after operation. After the initial six-week evaluation period, observations of these segments were continued through a series of monthly radiographs. Distraction began on postoperative day seven in group A and on day eleven in group B; and continued at a rate of 1 mm/day and a frequency of 4 times/day. Group A displayed new bone formation earlier than group B: group A's mean was 16.5 ± 4.9 days, while B's mean was 25.3 ± 4.6 days. The first bridging callus occurred earlier in group A than it did in group B: A's mean was time of 36.7 ± 9.9 days, while B's mean was 44.0 ± 7.9 days. There was no significant difference between groups A & B in terms of first cortical formation : A's mean was 86.9 ± 24.0 days, and B's mean was 100.6 ± 25.2 days. There was no significant difference between groups A & B in terms of the bone healing index : A's mean was 41.6 ± 13.5 days and B's mean was 41.15 ± 8.10 days.

Pathological study was performed on the 135 cases (137 lesion) of early gastric cancer (EGC) diagnosed during the period from 1970 to 1988. The gastrectomy specimens were obtained from Pusan National University Hospital and Pusan Paik Hospital. The statistical analysis was applied on the point of pathological and epidemiological aspects. The results obtained were summarized as follows: 1) The proportion of patients with EGC of all gastric cancer diagnosed in Pusan area during the period of 1970 to 1974 was 1.3%, those during 1975 to 1979 was 1.7%, those during 1980 to 1984 was 7.8%, and those during 1985 to 1988 was 20.0% respectively. 2) The model age group was 6th decade in both sexes. The average age of patients with EGC was 50. 1-year-old in men and 47. 9-year-old in women respectively. The sex ratio (M/F) was 2 : 1 but it was lower for young people than for old people. 3) The proportion of sites involved by the EGC in the stomach was as follows : the antrum 61%, the body 39%, and the cardia and fundus 0.01%. The intestinal type cancer more frequently involved the lower portion than the upper portion of the stomach. 4) Regarding the distribution of the gross types of EGC, the elevated group (Type I, IIa) accounted for 14%, the flat type (Type IIb) accounted for 4%, and the depressed group (Type IIc, III) accounted for 82%. There was no correlation between the gross type and the depth of the lesion. The elevated group was more frequent in intestinal type than in diffuse type. 5) The size distribution of the EGC was as follows : 46% of the lesions were smaller than 2.0 cm in diameter, 47% were between 2.1 to 5.0 cm, and 7% were larger than 5.1 cm. There was no correlation between the size of the lesion and the gross type. 6) The intestinal type of EGC was 77 lesions (56.2%) and the diffuse type 60 lesions (43.8%). The ratio of both types (I/D) was 1.3 : 1, and it was lower for younger people than for old people. 7) Ten of 135 cases (7%) had lymph node metastases. The metastatic rate of EGC confined to submucosa was much higher than that of EGC confined to mucosa only, but the metastatic rate was not related with the size of the lesion.

BACKGROUND: To identify the prevalence and related factors for vitamin D deficiency in the patients who admitted to the medical intensive care unit (ICU) of a Korean tertiary care hospital. METHODS: We retrospectively analyzed the data from ICU patients requiring mechanical ventilation (MV) for a period of > 48 h to identify the prevalence and associated factors for vitamin D deficiency. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D [25(OH)D] level < 20 ng/mL. RESULTS: Among 570 patients admitted to the ICU, 221 were enrolled in the study, 194 in the vitamin D deficient group and 27 in the non-deficient group. Prevalence of vitamin D deficiency in critically ill patients was 87.8%. The patient age was lower in the vitamin D deficient group compared with the non-deficient group (64.4 ± 15.4 vs. 71.0 ± 9.6 years, p = 0.049). A higher acute physiology and chronic health evaluation II (APACHE II) score (odds ratio [OR] 1.23, 95% confidence interval [CI] 1.10-1.37) and chronic illness (OR 3.12, 95% CI 1.08-9.01) were associated with vitamin D deficiency after adjusting for age and body mass index. Clinical outcomes of duration of MV, ICU stay, and 28- and 90-day mortality rates were not significantly different between the vitamin D deficient and nondeficient groups. CONCLUSIONS: Vitamin D deficiency was common in critically ill patients, particularly among younger patients. Higher APACHE II score and chronic illness were associated with vitamin D deficiency.

Most of the breast cancer revealed mass and/or microcalcifications on mammography. We analyzed morphologic characteristics of the masses and microcalcifications on mammography which confirmed as breast cancer pathologically. Of all 54 cases, 4 patients (7%) showed microcalcification only, 27 patients (50%), mass only, and the other 23 patients (43%), both microcalcification and mass on the mammography. The margin of the breast mass were ill-defined in 37 cases, well-defined in 8 cases, and well-defined with surrounding infiltration in 5 cases. The morphologic characteristics of the microcalcification were punctate-linear-V shape in 11 patients, punctate-linear shape in 9 patients, and punctate shape in 7 patients.

Myotonic dystrophy is the most common systemic disease causing myotonia. We report the case of respiratory failure in a patient with myotonic dystrophy after laparoscopic cholecystectomy. We carried out neurologic testing, electromyography and DNA testing in this patient and electromyography in the family of the patient. Through electromyography and DNA testing, this patient was diagnosed with myotonic dystrophy type I. Myotonic dystrophy is characterized by gradual decline of muscle tone and myotonia. It is important that this disease be excluded through preoperative history taking, physical examination and family history taking.

Kerion celsi is severe inflammatory type of tinea capitis. It occurs almost exclusively in pre-pubertal children. We report a case of Kerion celsi occuring in a 79-year-old woman. Culture of infected hair on Sabouraud glucose agar showed Microsporum canis Farnily history and fungus study suggested the importance of indirect route in Microsporum canis infection.
