OBJECTIVE: The patients with spinal cord injury (SCI) suffered by a lot of complications that influence the quality of life both physically and mentally. The purpose of this study was to evaluate the epidemiology of patients with spinal cord injury in incidence of the complication according to the injury level and period. METHOD: Retrospective study was done in 554 patients with SCI who discharged from Yonsei University Medical Center from January, 1987 to December, 1996. We investigated the incidence of each complication such as respiratory, cardiovascular, genitourinary, musculoskeletal, and dermatologic complications according to the neurologic level and each period (1987~1991, 1992~1996). RESULTS: Among the 554 cases, urologic complication (40.3%) was the most common complication followed by dermatologic (39.0%), musculoskeletal (33.6%), cardiovascular (27.1%) and so on. The most common complications of each system were autonomic dysreflexia (13.2%) in cardiovascular, pneumonia (9.6%) in respiratory, contracture (27.8%) in musculoskeletal, urinary tract infection (34.3%) in urologic, hemorrhoid in gastrointestinal, and central pain (24.0%) in neurogenic complications. The most common site of pressure sore was sacral area (58.9%). There was no significant difference in each complication according to the injury period. CONCLUSION: Urologic complication was the most prevalent in patients with SCI followed by dermatologic, musculoskeletal and so on. These basic results would be helpful for prevention and management of the complication of SCI.

OBJECTIVE: To find out the changes of the plantar pressure distribution of foot and the pathway of center of pressure (COP) in normal preschool children with age. METHOD: Thirty-eight normal children aged 1 to 6 were participated in this study. We divided into three groups according to the age. Foot contact area, pressure of the foot and pathway of COP were measured using F-scan in-shoe measuring system (Tekscan Inc.) during the gait. RESULTS: The ratio of midfoot contact width to forefoot contact width was decreased with age (p<0.05). And the relative pressure of the medial midfoot was decreased with age (p<0.05). In the analysis of COP, the ratio of anteroposterior length of COP to total contact length was significantly increased (p<0.05), and the ratio of mediolateral width of COP to forefoot contact width was tend to decrease. CONCLUSION: We can identify the characteristics and changes of the foot pressure distribution and the pathway of COP in preschool children with normal foot using F-scan system. These quantitative data of foot scan are useful for evaluating the foot pathology in preschool children during the gait.

Bronchopulmonary Sequestration*

Purpose: To assess the prevalence and progression of a stage 0 macular hole in the fellow eye of patients with an idiopathic full-thickness macular hole.
Methods: The fellow eyes of 189 patients who underwent idiopathic full-thickness macular hole surgery were examined by biomicroscopy and spectral domain-optical coherence tomography (SD-OCT). A subset of 21 fellow eyes with a stage 0 macular hole was observed. Changes in the macular hole were evaluated by biomicroscopy and SD-OCT for an average of 29 months.
Results: Among the 21 eyes, 15 showed no change in perifoveal vitreous detachment (71.4%). Two eyes (9.5%) developed complete vitreofoveal separation, and one of the two developed a separation after progression to stage 1A. Among 21 eyes, 5 (23.8%) developed above stage 1A, and one of the five progressed to stage 1B after five years, which was successfully treated with vitrectomy and gas tamponade.
Conclusions Perifoveal vitreous detachment in the fellow eye on SD-OCT, defined as a stage 0 macular hole, occurred at an earlier phase than stage 1A macular holes and may progress to an advanced stage. Therefore, patients who undergo macular hole surgery and have a stage 0 macular hole or perifoveal vitreous detachment in the fellow eye should be followed closely.

Malignant tumors of the maxilla represent about 3-4% of head and neck malignant neoplasm and the origins are maxillary gingiva, hard palate and maxillary sinus. We are to investigate clinical features and results according to various treatment modalities of maxillary malignant tumor to get information for better treatment results. Sixty patients with malignant maxillary tumors treated at Yonsei medical center from 1992 to 1997 were studied retrospectively. They are evaluated according to clinical signs & symptoms, stages at first diagnosis, primary site, histopathologic features, treatment method, recurrence and survival rate with clinical records, biopsy results and CT radiograph. The most common primary site was maxillary sinus and most common histopathology was squamous cell carcinoma. The local recurrence rate was 18% at 5 years, neck failure was 3% and distant metastasis was 18%. Overall survival rate was 78% at 2 years and 69% at 5 years. Failure at primary site is the main problem in the curative treatment. So, to improve survival in these patients efforts should be directed toward improvement of local control.

PURPOSE: To identify risk factors that affect the development of type 2 retinopathy of prematurity (ROP) and progression to type 1 or threshold ROP requiring treatment. METHODS: The medical records of premature infants born with a birth weight ≤1,500 g or a gestational age ≤32 weeks were retrospectively reviewed. Potential risk factors were divided into systemic and ophthalmic factors and analyzed by univariate and multivariate logistic regression analyses. RESULTS: Three hundred and twenty-four eyes met the screening criteria. Among them, 41 eyes (12.65%) progressed to type 2 ROP and 21 eyes (6.48%) received treatment after progression to type 1 or threshold ROP. The systemic risk factor associated with progression from type 2 ROP was periventricular leukomalacia and the ophthalmic factor was the existence of nasal ROP at the time of diagnosis of type 2 ROP. CONCLUSIONS: Careful examination was needed when type 2 ROP with periventricular leukomalacia or nasal ROP developed because there was a high probability of progression and treatment.

PURPOSE: Whereas sexual function has long been assumed to be an important component of adult men's lives, the impact of sexual dysfunction has not been estimated in parallel to other modern disease entities. We compared the seriousness of erectile dysfunction (ED) with that of other diseases by use of self-administered questionnaires. MATERIALS AND METHODS: Between January 2012 and July 2012, 434 healthy male volunteers (group 1) and 263 ED patients (group 2) were enrolled. The questionnaire consisted of the following: "If you must undergo only one disease in all your life, which disease could you select among these items or ED?" The comparative disease entities included hypertension, diabetes mellitus (oral hypoglycemic agent/insulin injection), hemodialysis, myocardial infarction, herpes zoster, chronic sinusitis, chronic otitis media, gastric cancer (early/late), lung cancer (early/late), liver cancer (early/late), and dementia. RESULTS: Group 1 recognized ED as being a more serious disease than hypertension, diabetes mellitus (oral hypoglycemic agent), herpes zoster, chronic sinusitis, and chronic otitis media. In comparison, group 2 recognized ED as being a more serious condition than diabetes mellitus (insulin injection) and dementia (p<0.001 and p<0.001, respectively). In particular, ED was deemed to be more serious than hemodialysis, gastric cancer (early), lung cancer (early), and liver cancer (early) by men in group 2 in their 30s to 40s, and these results were statistically significant compared with the same age subgroups in group 1 (p<0.001, p<0.007, p<0.02, and p<0.007, respectively). CONCLUSIONS: In contrast with their healthy counterparts, Korean men with ED recognized ED as being as serious as hemodialysis, dementia, and early stage cancer, which reflects the severe bother of ED in Korean patients.

Infertility due to ejaculatory failure and poor semen quality is a main problem for sexual dysfunction of spinal cord injured (SCI) men. A 27-year-old paraplegic man who wished to father children was induced to repeated ejaculations for eight times with a rectal probe electrical stimulation at one or two weekly interval. For the 4th to 8th stimulations, the subject took pseudoephedrine 20 mg, three times a day orally to improve the semen quality. We report a triplet childbirth between the SCI man and his healthy wife through the ejaculatory stimulations in conjuction with advanced reproductive techniques such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).
