The major objective of this research is to identify those hospital characteristics that best explain cost variation among hospitals and to formulate linear models that can predict hospital costs. Specific emphasis is placed on hospital output, that is, the identification of diagnosis related patient groups (DRGs) which are medically meaningful and demonstrate similar patterns of hospital resource consumption. A casemix index is developed based on the DRGs identified. Considering the common problems encountered in previous hospital cost research, the following study requirements are established for fulfilling the objectives of this research: 1. Selection of hospitals that exercise similar medical and fiscal practices. 2. Identification of an appropriate data collection mechanism in which demographic and medical characteristics of individual patients as well as accurate and comparable cost information can be derived. 3. Development of a patient classification system in which all the patients treated in hospitals are able to be split into mutually exclusive categories with consistent and stable patterns of resource consumption. 4. Development of a cost finding mechanism through which patient groups' costs can be made comparable across hospitals. A data set of Medicare patients prepared by the Social Security Administration was selected for the study analysis. The data set contained 27,229 record abstracts of Medicare patients discharged from all but one short-term general hospital in Connecticut during the period from January 1, 1971, to December 31, 1972. Each record abstract contained demographic and diagnostic information, as well as charges for specific medical services received. The "AUTOGRP System" was used to generate 198 DRGs in which the entire range of Medicare patients were split into mutually exclusive categories, each of which shows a consistent and stable pattern of resource consumption. The "Departmental Method" was used to generate cost information for the groups of Medicare patients that would be comparable across hospitals. To fulfill the study objectives, an extensive analysis was conducted in the following areas: 1. Analysis of DRGs: in which the level of resource use of each DRG was determined, the length of stay or death rate of each DRG in relation to resource use was characterized, and underlying pattern of the relationships among DRG costs were explained. 2. Exploration of resource use profiles of hospitals; in which the magnitude of differences in the resource uses or death rates incurred in the treatment of Medicare patients among this study hospitals was explored. 3. Casemix analysis; in which four types of casemix-related indices were generated, and the significance of these indices in the explanation of hospital costs was examined. 4. Formulation of linear models to predict hospital costs of Medicare patients; in which nine independent variables(i.e., casemix index, hospital size, complexity of service, teaching activity, location, casemix-adjusted death rate index, occupancy rate, and casemix-adjusted length of stay index) were used for determining factors in hospital costs. Results from the study analysis indicated that: 1. The system of 198 DRGs for Medicare patient classification was demonstrated not only as a strong tool for determining the pattern of hospital resource utilization of Medicare patients, but also for categorizing patients by their severity of illness. 2. The weighted mean total case cost(TOTC) of the study hospitals for Medicare patients during the study years was $1127.02 with a standard deviation of $117.20. The hospital with the highest average TOTC ($1538.15) was 2.08 times more expensive than the hospital with the lowest average TOTC ($745.45). The weighted mean per total cost (DTOC) of the study hospitals for Medicare patients during the study years was $107.98 with a standard deviation of $15.18. The hospital with the highest average DTOC ($147.23) was 1.87 times more expensive than the lowest average DTOC($78.49). 3. The linear models for each of the six types of hospital costs were formulated using the casemix index and the eight other hospital variables as the determinants. These models explained variable to the extent of 68.7 percent of total case cost (TOTC), 63.5 percent of room and board cost (RMC), 66.2 percent of total ancillary service cost (TANC), 66.3 percent of per diem total cost (DTOC), 56.9 percent of per diem room and board cost (DRMC), and 65.5 percent of per diem ancillary service cost (DTANC). The casemix index alone explained approximately one half of inter-hospital cost variation; 59.1 percent for TOTC and 44.3 percent for DTOC. These results demonstrate that the casemix index is the most important determinant of inter-hospital cost variation. Future research and policy implications in regard to the results of this study is envisioned in the following three areas: 1. Utilization of casemix-related indices in the Medicare data systems. 2. Refinement of data for hospital cost evaluation. 3. Development of a system for reimbursement and cost control in hospitals.

One of the most important aspect of hemophilia is repeated bleeding into the joint. The frequency of such hemorrhages varies with the severity of the disease. In moderate or severe cases, repeated hemorrhages result in considerable impairment of joint structure and function: Contractures and gross deformity are frequent end result. This paper described a case of hemophilia A, 24-year-old male, who developed deformity of the shoulder, elbow, ankle and knee joint because of repeated hemoarthrosis. Author attempted to treat this patient by transfusion of fresh whole blood and traction, which resulted in some clinical improvement.

Vertebral pedicle screws have been widely used for secure posterior spinal fixation. When postoperative CT scan films were made, the blurring of pedicle screws were observed and we could not figure nut the exact diameter of screw and canal encroachment. There is no information in the difference hetween actual diameter and measured diameter of pedcile screws in CT yet. In this study, we try to find out partial voiume averaging artifact of pedicle screws made of stainless steel and titanium. Partial volume averaging artifact occurs when the shape of an object changes within the thickness of the CT slice or when a relatively small object is only partially included within the slice. Four pig cadaveric spinal column including 6 vertebrae each were prepared and CT scans were performed after insertion of C-D screws(stainless steel) to the left and TSRH screws(titanium) to the right pedicle. Another CT scans were performed after insertion of C-D screws to the right and TSRH screws to the left pedicle. The third CT scans were made after removal of all the pedicle screws. Actual C-D screw diameter was 6mm and CT scanned diameter was 8. I 6+/-0.66mm. Actual TSRH diameter was 6.5 mm and CT scanned diameter was 6.59+/-0.34mm. In conclusion, stainless steel has more partial volume averaging artifact than titanium. Safety margin of pedicle screw made of stainless steel is about 2mm and that of titanium is about 1 mm.

Infantile hypertrophic pyloric stenosis(IHPS), which occurs three of 1,000 live births, is a major cause of 1 nonbilious vomiting of early infancy but its etiology and pathogenesis are still obscure. The operation of pyloromyotomy as described by Ramstedt in 1912 remains the standard of care for the treatment of IHPS. From January 1993 to October 1996, 35 infants with IHPS were surgically treated and the following results were obtained. 1. Thirty-five patients comprised 32 males and 3 females, and the ratio of male to female was 10.7:1. 2. The most prevalent age group was between 2 weeks and 8 weeks. 3. Of 35 infants, first born babies were 23 cases(65.7%). 4. Breast feeding was in 23 cases(65.7%). 5. The body weight percentile at admission was lower than 50 percentile in all 35 cases. 11. A total of seven associated anomalies were noted in six patients. 12. All 35 cases were treated with Fredet-Ramstedt pyloromyotomy. 13. There were postoperative complications of wound infection in 2 cases. Intermittent nonprojectile vomiting was presented in 8 cases(22.9%) after operation, but one of them was relieved in 13 days and the rest were relieved within one week by adjustment of oral intake.

Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection (prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricture, impacted stone, Cunningham clamp or condom catheter) and trauma (instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors, 1) a ureteral or bladder calculus that is lodged in the urethra 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum combined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

Pseudohypoparathyroidism(PHP) is an inherited metabolic disorder characterized by hypocalcemia, hyperphosphatemia and an impaired phosphaturic response to exogenous parathormone(PTH), which are caused by end organ resistance to the action of PTH. Most of these patients have, in addition, the skeletal abnormalities of Albright hereditary osteodystrophy. We report two cases of PHP, suspicious type Ia, in sibling who were presented with multiple subcutaneous soft tissue calcification similar to that seen in tumoral calcinosis and had short stature, round face, brachydactyly and metabolic abnormalities(hypocalcemia, hyperphosphatemia, increased serum PTH, and decreased 24hr urinary basal cAMP)

Immunosuppressive therapy based on the use of antilymphocyte globulin (ALG) has become standard therapy for patients with splastic anemia who are not eligible for bone marrow transplantation. In this study, T cell subsets before and after ALG therapy, hematologic responses, complications and prognostic factors were analysed. Eleven (42%) out of twenty-six patients treated with ALG showed response, but two patients showed relapse. Most of the response (9 cases) was noticed within 6 months after the initiation of ALG therapy (median: 3 months). The main complications of ALG therapy were fever (91%), thrombocytopenia (86%), neutropenia (63%), and serum sickness (56%). Four patients were died just ALG therapy because of serum sickness (2 cases), intracranial hemorrhage (1 case), and shock (1 case). Short interval from diagnosis to treatment suggested to show good response (P=0.0575), but it was not significant statistically. Lymphocyte subsets were measured in the blood of 23 patients. Helper T/suppressor T cell ratio (T4/T8 ratio) at the initiation of ALG therapy (day 0) was higher significantly in patients who were responded (P=0.0299). The patients who showed above 1.0 of T4/T8 ratio on day 0 might be speculated good response (P=0.032). More difference of T4/T8 ratio between day 14 after ALG therapy and day 0 might show good response (P=0.0673). Then the actuarial probability of survival at 3 years in patients treated with ALG was 77%. Our data suggest that ALG therapy may be used as an alternative treatment to bone marrow transplantation, and T4/T8 ration of peripheral blood at the initiation of therapy may be used as one of the prognostic factors.
