In Albright's hereditary osteodystrophy (AHO) including the syndromes of pseudohypoparathyroidism (PHP) and pseudopseudohypoparathyroidism (PPHP), multiple areas of intracutaneous ossification are often encountered. The characteristic features are short stature, round face, short neck, obesity, cutaneous ossifications, and various skeletal anomalies including short metacarpal and metatarsal bones, curve of radius, and brachydactyly. The patient was a 10-month-old male infant. He presented slightly depressed erythematous hard plaques on the left upper chest and left thigh. We had taken biopsies from both skin lesions, confirming cutaneous ossification or bone formation. He also had the characteristic features of AHO. He had a history of admission due to patent ductus arteriosus and atrial septal defect. The laboratory results showed slightly decreased calcium, increased phosphorus and PTH levels. The patient received no specific corrective measures because his calcium and phosphorus levels were not far from normal values until newly developed similar skin lesions appeared.

The employment of segmental pedicle screw instrumentation has greatly enhanced the correction of scoliotic deformity. However there is still much controversy on the ability of the system to correct the rotational deformity. This prospective study with 12 idiopathic throacic scoliosis patients subjected to segmental pedicle screw instrumentation was performed to determine the effect of the system on the rotational deformity of idiopathic throacic scoliosis. In addition to the standing films to measure the magnitude of scoliotic curvatures, preand postoperative CT were utilized for the measurement and comparison of angle of rotation relative to the sagittal plane(RAsag.), relative rotation with reference to the upper and lower end vertebrae(RAend), relative rotation with reference to the sacrum(RAsac.), frontal translation(TF) and sagittal translation(TS) for the apical vertebrae. Despite the high correction rate obtained in the frontal plane(average 71.1%) and normalization of sagittal contour, the rotational corrections were statistically insignificant in all parameters and showed no significant correlation to the correction of the curvatures nor horizontal plane displacement as represented by the frontal and sagittal displacement. In conclusions, the segmental pedicle screw instrumentation with rod derotation does not produce significant derotation by itself.

OBJECTIVE: Using the standardization of disease diagnosis of disease, and surgical procedures, the authors have made a clinical application for the analysis of inpatient data with the ability to search for information pertinent for writing of clinical articles. METHODS: A client-server system and database software was developed for networking. For clinical application, a computerized daily report has been developed. Data from Neurosurgical patients admitted at Soonchunyang University Hospital from January to December 1998 were analyzed with this system. Data for clinical articles was obtained using the search mode, information such as orbital infarction syndrome following intracranial aneurysm surgery and epidemiological analysis or geriatric neurosurgical patients. RESULTS: For the daily report it takes approximately 10 minutes to input the patients demographic information, name of disease, diagnosis and surgical procedure. The daily report also numbers and sorts the inpatients according to large categories of diagnosis, reports the ratio between inpatients and operative patients. The annual report that was obtained was very accurate and gave rapid statistics for the one year. By retrospective study for the past 18 years, we calculated the incidence of orbital infarction syndrome following intracranial aneurysm surgery as 1.4%, and also estimated the population of geriatric inpatients as 18.3% by retrospective study. CONCLUSIONS: It has been found to be most useful to make a daily and annual report for tracking and research purposes. For use in clinical articles, it can be possible to do a search of the patients using the standardized disease, diagnosis and neurosurgical procedures application and obtain pertinent information in a timely manner.

OBJECTIVE: The the international classification of disease and surgical procedure has been found to be a lengthy and time-consuming text for use by neurosurgeons. A more subject matter related classification system is needed for use by this specialty. The author has developed a more comprehensive and standardized classification system specified for diagnosis of neurological disease and neurosurgical procedures. METHODS: Standardization of disease was completed by modifying the name of disease according to that which was used for daily report past 10 years, and from textbook of neurosurgery. The fields of international coding are continued in each. Neurosurgical procedures were designated and modified according to Current Procedure Terminology 96. Client-server system will be used for networking and database software applications have been developed. RESULTS: Disease was classified in 14 large categories and 379 subcategories. Diagnosis was classified in 12 large categories and 43 subcategories. Neurosurgical procedure has 20 large and 202 subcategories. The international coding system such as ICD-10 and ICD-9CM is maintained for the diagnosis and procedures to each category. CONCLUSIONS: It could be possible to make and use a standardized database model of disease, diagnosis and neurosurgical procedures to be used by physician.

The purpose of this study was to estimate the prevalence and to identify risk factors of overweight among preschool children in Korea. The study subjects were 750 children, aged 2-6, attending child care centers in Korea. A measurement of the height and weight of the children, as well as collection of wide range of variables including general characteristics, and potential factors related with dietary habit for children and their parents, were conducted. Overweight was defined based on more than 110% of ideal body weight. A logistic regression analysis was adopted to identify the factors associated with overweight. Subjects were classified into three categories according to the obesity index : underweight(PIBW<90%, n=34), normal(90%< or =PIBW<110%, n=577), and overweight(PIBW> or =110%, n=139). The overall prevalence of overweight and underweight of the subjects were 21.3% and 4.0% of the boys and 15.5% and 5.1% of the girls respectively. Parent's obesity was associated with a higher risk of overweight on girls. Subjects o the third quartile(girls) and fourth quartile(boys) of income level had a substantially higher risk of overweight than did those in the first quartile. Fast eating, overeating, and food prejudice were also associated with an increased risk of overweight. The results of a logistic regression analysis showed that the eating habits and food preferences of the children were the most influencial factors on overweight. These finding may imply the importance of early stage nutrition education on rational dietary habit to prevent prevailing obesity of preschool in Korea.

It has been known that right side bypass tract ablation is more difficult and has higher recurrence rate than that of left side bypass tract, and often associated with atrioventricular block in patients with septal bypass tract. Multielectrode basket catheter (MBC) allows simultaneous rapid acquisition of numerous electrical signals generated by a selected surface area or volume of myocardium. We experienced two cases of successful catheter ablation of atrioventricular reentrant tachycardia by right septal bypass tract which were mapped by MBC with greater ease.

OBJECTIVE: Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement.METHODS: In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height of the PLL and compared them with other landmarks such as the disc and the pedicle.RESULTS: Horizontally, at the upper margin of the disc, the central portion of the superficial PLL covered 17.8–36.9% of the disc width and the fan-like portion of the PLL covered 63.9–76.7% of the disc width. At the level of the median portion of the disc, the PLL covered 69.1–74.5% of the disc width. Vertically, at the level of the medial margin of the pedicle, the fan-like portion of the PLL covered 23.5–29.9% of the disc height. In general, a significant difference in length was not found in the right-left and male-female comparisons.CONCLUSION: This study presents the morphometric data on the pattern of intervertebral disc displacement and helps to improve the knowledge of the surgical anatomy of the lumbar PLL.

Pachydermodactyly is a form of digital dermal fibromatosis of unknown etiology, characterized by asymptomatic soft tissue swelling on the lateral aspects of the proximal interphalangeal joints of the hands. It usually affects young men and often associated with repetitive mechanical trauma. As a rule, it is a benign condition and a specific therapy or extensive investigation is not necessary in most cases. However, pachydermodactyly is not well recognized by physician. So it can be confused with other rheumatic conditions, such as rheumatoid arthritis or juvenile idiopathic arthritis. A prompt diagnosis is crucial for preventing inappropriate or possible toxic treatment. We describe a case of pachydermodactyly in a 20-year-old military man, who had painless swellings of the hand joints.
