An epidemiological investigation of 878 workers(male 812, female 66) who suffered from low back injury(LBI) in some workplace of Pusan city from January 1 to December 31 in 1992 was carried out to obtain the various informations of the prevention and management in the occupational low back pain(LBP). The results were summarized as follows: 1. The mean age of LBP workers was 39.3±10.4(18-67) in male 48.5±12.6(21-69) in female workers. And the most common age groups were the 4th decade in male and the 6th decade in female workers. 2. In the frequency distribution of LBI according to the kind of industry, manufacturing industry was most frequent, and industry of construction, transport-storage-communication were the next in order. Among manufacturing industry, LBI of metallic products and machinery was the most frequent. 3. The occupational frequency of LBP was technical worker, monotonous worker, driver of automobile, driver of heavy equipment and office worker in order. 4. The cumulative percentage of LBI was 6.9% at the first day of employment and 90.8% until 10 years after employment. 5. The mean working duration from employment to onset of injury was 1081 days(about 2.9 years) and the working duration according to occupation was the shortest in driver of heavy equipment(502 days) and longest in office worker(1982 days). 6. The careless handling of object was the most common cause of LBI, and fall down, slip down, collision and traffic accidents were the next in order. 7. The most common cause of LBI according to occupation was traffic accident in driver of automobile, fall down in driver of heavy equipment and careless handling of object in office worker respectively. 8. The case of localized LBI were 517(58.9%) and the cases of LBI combined with other injuries, such as head, neck, trunk, arm or leg, were 361(41.1%) 9. Lumbar sprain was the most frequent diagnosis of LBI, and Herniated Nucleus Pulposus(HNP) and lumbar fracture were the next in order. 10. In multiple injuries, LBI combined with multiple body injury was the most frequent, and the next was LBI combined with arm and leg, with trunk, with head and with neck in order. 11. LBI combined with multiple body injury was the main injury in fall down, slip down and traffic accident, and lumbar sprain was the main injury in careless handling of object.

We evaluated median value and lower confidence limit of total serum IgE level in each age group of 1,493 pure atopic dermatitis patient without respiratory atopic diseases. The results were as follows . 1. The median value of total serum IgE level of each age group in patients with atopic dermatitis distributed from 56.5 IU/@Ll to 660It.J/C. The distributions of the median value of total serum IgE levels of total patients with atopic dermatitis, total male patients with atopic dermatitis, and total female patients with atopic dermatitis were 185 IU/C, 220 IUj'@C, and 165 IUj'C. There was no statistical significance of median value of total serum IgE level between mole patients and female patients. 2. The 95% and 99% lower confidence limit(one-sided) of total serum IgE level of ea.ch age group in patients with atopic dermatitis distributed from 32.6 IU /n4 to 287IU/v4 and from 31 IU/m0 to 202 IU4. The 95% lower confidence limit (one-sided) of total serum IgE level of total patients with atopic dermatitis, tatal male patients with atopic dermatitis, and. total female patients with atopic dermatitis were 170 II.J/m0, 185 IU,m/l, and 133 IUm/l. The 99% lower confidence limit.(one-sided) of total serum IgE level of total patient with atopic dermatitis, total male patient with atopic dermatitis, and total female patients with atopic dermatitis were 165 IU/ml, 180 IU/ml, and 125 IU/ml.

Ankle fractures in children often involve the physis. They are of particular importance because partial or entire growth arrest can occur and result in significant complications. We followed thirty-four ankle fracture involving distal physis of tibia and fibula for more than 1 year and analyzed them using the modified Salter-Harris classification, the Dias-Tachdjian classification and the type of fracture (closed or open), Complications occurred in eight cases (23.5%) – two of twenty-six closed fractures (7.7%) and six of eight open fractures (75%). The complications were more significant in open fractures. Angular deformity (5 cases), limb-length discrepancy (4 cases), incongruity of the joint surface (2 cases), fibular overgrowth (2 cases) and synostosis (1 case) occurred alond or combined. In three cases of them we performed surgical management (bone bridge resection or/and supramalleolar corrective osteotomy) and had satisfactory results. This study suggests that the incidence of complications is difficult to anticipate, but is correlated with severity of initial injuries of growth plate and soft tissue, and is much higher in open fracture. After physeal injury, children should be followed until skeletal maturity and the severe deformities can be prevented by early detection and correction of growth plate disturbance.

BACKGROUND: Androgenetic alopecia is a common problem, affecting approximately 50 percent of men and perhaps many women, over the age of 40 in Caucasians. There have been several reports about the prevalence and types of androgenet clopecia in the general population of Caucasians however the prevalence and types of and renetic alopecia has not been reported in the general population of Korea. OBJECTIVE: Our purpose was to ascertain the prevalence ar d ypes of androgenetic alopecia in Koreans and to compare it with that of the Caueasian. METHODS: A survey on the prevalence and clinical types of aidrogenetic alopecia was conducted by one dermatologet from July to September, 1993. The total number of subjects was 1224 males and 1094 females. RESULTS: The following esults were obtained from this sudy l. In men, the prevalence rate of androgenetic alopecia increased steadily with advancing age and the prevalence rate of more advanced degrees of alepcia(types V, VI and VII) remained relatively low until the seventh decade of life. The preralence rates until the age of sixties in Korean men were lower than that of the white and is pattern became closer with that of the white after the seventies. 2. In Korean women, the prevalence rate of androgenetic was lower than that of the white until fifties and it increased markedly after sixties. CONCLUSION: The prevalence rate of androgenetic alopecia in Korean was lower than that of the Caucasian. Our data adicates that Korean men have a late onset of baldness and more preservation of the frontal hair line with decreased frequencyte frontoparitetal loss than the Caucasian.

Ectopic pregnancy refers to gestation in which the fertilized ovum implants on any other tissure than tbe mucus membrane lining the uterine cavity. Cornual (intertitial) pegnancy is a relatively uncommon but potentially catastrophic form of ectopic pregnancy, defined as implantation in the intramural portion of a fallopian tube. A hydatidiform mole usually occupies the uterine cavity but it's occurrence in the uterine tube is extremely rare. Only a few cases of primary hydatidifm mole of the tube have been reported. We experienced a case of ectopic hydatidiform mole in the uterine cornua and so present it with brief review of literatures.

PURPOSE: To report a case of an acquired dacryocystocele successfully treated with bicanalicular silicone intubation and to review relating literature. CASE SUMMARY: A 17-year-old girl visited our clinic with tearing of both eyes since birth and a mass on the right medial canthal area for 2 years. A firm, non-tender mass with a well-demarcated border was palpated in the subcutaneous level just inferior to the right medial canthal ligament. Lacrimal irrigation via the lower punctums showed reflux through the opposite punctums without nasal passage in both of her eyes. Computed tomographic scan showed a widening of the right lacrimal sac fossa and bony nasolacrimal canal and a 16 x 18 mm sized cyst-like mass in the right lacrimal sac. The patient was diagnosed with right acquired dacryocystocele associated with bilateral congenital nasolacrimal duct obstructions. After opening of the obstructed common canaliculus using a fine lacrimal probe, silicone intubation was performed. The tearing symptom improved and the mass disappeared during the subsequent follow-up period of 1 year. CONCLUSIONS: When only accompanied by distal nasolacrimal duct obstruction, acquired dacryocystocele can be inferred to be associated with congenital nasolacrimal duct obstruction. Subsequently, bicanalicular silicone intubation can be considered as a treatment of choice.

Sjogren-Larsson syndrome is a rare autosomal recessive neurocutaneous disorder due to a deficiency of the fatty aldehyde dehydrogenase. It consists of ichthyosis, spastic di- or quardriplegia and mental retardation. We report a case of a 9-year-old boy who was suspected to have Sjogren-Larsson syndrome. He had congenital ichthyosis, spastic diplegia and mental retardation. In addition, there was macular degeneration on the fundus. His neurological symptoms were improved after selective posterior rhizotomy and rehabilitation therapy. However, the dermatological problem did not subside with conservative treatment.

PURPOSE: To compare the results of posterior cruciate ligament reconstructions by tibial inlay and tibial tunnel techniques. MATERIALS AND METHODS: Despite of conservative treatment, all patients (31 cases) had pain and grade 2 or more posterior instability. Posterior drawer test and posterior drawer stress radiography were performed. Clinically, Lysholm knee score and Tegner activity score were evaluated. RESULTS: In the tibial tunnel group, posterior drawer test demonstrated grade 1 instability in 7 cases, grade 2 in 4 cases, and grade 3 in 1 case at the last follow-up. In the tibial inlay group, there was grade 1 instability in 14 cases and grade 2 in 5 cases. On posterior drawer stress radiography, the mean side-to-side difference in measurement of the tibial tunnel group improved from 12.4 mm preoperatively to 4.0 mm at follow-up, and that of the tibial inlay group improved from 11.8 mm to 2.9 mm. Lysholm knee score and Tegner activity score improved to 86.8 points and 5.83 points, respectively, in the tibial tunnel group, and to 88.2 points and 5.84 points, in the tibial inlay group. CONCLUSION: PCL reconstruction with the tibial inlay technique tends to maintain better posterior stability, but there is no statistically significant difference between the two techniques. Further study may be required.

Eccrine poroma is a benign skin appendage tumor originating from the intradermal part of the sweat duct. It is found commonly on the hairless surface of the feet, although eccrine poroma of the hands, head, trunk, and legs have been reported. Histopathologically, the tumor extends from the lower portion of the epidermis into the dermis as broad, anastomosing bands. The tumor cells are smaller than squamous cells, having a uniform cuboidal appearance and a round, deeply basophilic nucleus, connected by intercellular bridges. In eccrine poromas, narrow ducta1 lumina and occasional cystic spaces are found within the tumor bands, but a large cystic space is very unusual. We report a case of eccrine poroma with a large cystic space extending from epidermis into the reticular dermis.

Segmental neurofibromatosis is a rare disorder characterized by cafe-au-lait spots and neurofibrobmas, or only neurofibroma, limited to one region of the body. Disease-associated systemic involvement is uncommon. Most patients with segmental neurofibromatosis do not have a family history of neurofibromatosis. In Korea, there have been 3 reported cases of segmental neurofibromatosis. None of them had caf6-au-fait spots, systemic involvement, or family history. This report describes a case of segmental neurofibromatosis in a 25-year-old woman who had Becker's nevus-like cafe-au-lait spots and this was linked to the presence of Fanconi's syndrome in a second degree relative of the patient.
