PURPOSE: This study was performed to evaluate the width of symphysis pubis and its radiographic appearance in different age and sex, and it was aimed to establish a radiographic diagnosis criteria for diastasis of the joint. MATERIALS AND METHODS: The width and the appearance of symphysis pubis were observed by pelvic X-ray in 92 males and 169 females who had no history of any joint disease. The mean width of symphysis pubis was calculated and data were analyzed by age, sex and parity using student t-test. RESULTS: The mean width of symphysis pubis was 2.88+/-0.71 mm in male group and was 3.24+/-0.68 mm in female group. It was 3.34+/-0.84 mm in parturient and 2.82+/-0.55 mm in nullipara and the difference between these two groups was significant (P<0.05). Osteoarthritic changes were noted in most cases over 60 irrespective of sex. CONCLUSIONS: Based on the results from this study and reported value of physiological relaxation of symphysis pubis through pregnancy and labor, a separation over 6 mm and/or a vertical migration over 3mm can be diagnosed as diastasis of symphysis pubis. This criteria would facilitate the earlier diagnosis of relaxation and separation of this joint by labor or trauma.

BACKGROUND: Despite the development of empiric antibiotics in treatment of neutropenic fever(NF) in pediatric cancer patients, bacterial infection is still the most important cause of death in these patients. In this study the authors analyzed clinical characteristics and tried to find out the possible risk factors of the pediatric cancer patients who succumbed to the documented bacterial infection after episodes of neutropenic fever. METHODS: 17 pediatric cancer patients expired after episodes of neutropenic fever(NF) in the pediatric department of Asan Medical Center from Mar. 1990 to Feb. 1996 were grouped by the results of bacterial culture. 7 cases (Group A) had documented bacterial culture results and 10 cases (Group B) had negative culture results. The clinical characteristics of these two groups were analyzed retrospectively. RESULTS: There were no differences in the types of cancer between the two groups. All the documented bacteria were gram negative organisms and all cultured from the blood. There were no differences between the two groups in the treatment duration, known risk factors of infection before and at the onset of fever, antibiotics administered, and interval from the onset of NF to the administration of antibiotics. The response rate of initial empiric antibiotics was lower in group A(14%) compared to Group B(40%), even though all the cultured organisms except 2 cases in Group A were sensitive to initial empirical antibiotics. Septic shock was the cause of death in 86% of Group A patients, but only in 10% of Group B patients. The other causes of death were progression of cancer, bleeding, hepatic failure, adult respiratory distress syndrome and multiple organ failure, which showed no difference between the 2 groups. The interval from the onset of fever to death was significantly shorter in Group A(6.2+/-2.3 days) compared to Group B(24.9+/-18.6 days). CONCLUSIONS: Bacterial infection is still the most frequent cause of death after NF. Most patients succumbed to the documented bacterial infection showed rapid progression of bacteremia to septic shock despite administration of sensitive antibiotics. The known risk factors of infection before the onset of NF and other treatment factors shows no differences between the two groups in this study. These results suggest that the bacteremia is obvious risk factor of poor outcome after NF episode, and antibiotics alone may be insufficient to prevent the rapid progression of septic shock in these patients.

BACKGROUND: Hemophagocytic lymphohistiocytosis(HLH) is a rare and fatal disorder in children. Recently its clinical characteristics and etiology of uncontrolled activation of cellular immune system in genetically predirected patients have keen elucidated. The authors analyzed the clinical characteristics and response to immunosuppressive agents of HLH patients in single institute. METHODS: The authors retrospectively analyzed various clinical data including CSF and bone marrow examination at diagnosis and follow up period in the 6 patients who were diagnosed as HLH at Asan Medical Center during last 2 years. Antithymocyte globulin(ATG : 10 mg/kg/day) and methylprednisolone(methyl-PD: 5 mg/kg/day) for 5 consecutive days as induction treatment and cyclosporin A(CsA) as maintenance treatment after induction with weekly intrathecal methotrexate for 5-6 weeks were given to the recently diagnosed 3 patients. RESULTS: All the patients except one were infants. Persistent fever, hepatosplenomegaly and pancytopenia were observed in all the patients. Family history of suspicious HLH was observed in 4 patients(67%). The characteristic elevated serum triglyceride(TG) level and/or decreased fibrinogen level were noted in all. Mild to moderate CSF pleocytosls with increased lymphocytes and monocytes was also observed in all during the disease course. Variable degree of nonqr-Langerhans cell histiocytic infiltration and hemophagocytosis were observed in all the cases. Of the 3 patients treated with ATG and methyl-PD, one achieved complete remission and the others achieved partial remission within 2 weeks of treatment, but all expired after 5 months, remission with CsA. Regardless of treatment regimen, all the 6 patients expired due to CNS sequelae of HLH. CONCLUSIONS: HLH mainly developed in infants. Persistant fever, hepatosplenomegaly and pancytopenia were observed in most cases with the characteristic change of serum TG and/or fibrinogen level. HLH should be included in the differential diagnosis in patients with these features especially when the family history of suspicious HLH is present, and histologic comfirmation of HLH could be easily accomplished with bone marrow study in most cases. Remission induction of HLH could be achieved with immunosuppressive treatment but it was difficult to maintain long term remission.

BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

BACKGROUND: To evaluate the effect of preoperative fatty degeneration of deltoid and teres minor muscles on the clinical outcome in patient with reverse total shoulder arthroplasty (RTSA). METHODS: Nineteen patients with RTSA were enrolled. The mean follow-up period was 16.1 months. The fatty degeneration of three distinct parts in each deltoid and the teres minor muscle was measured using a preoperative magnetic resonance imaging. Postoperatively, the muscle strengths for forward elevation (FE), abduction (Abd), and external rotation (ER) were measured using a myometer at the last follow-up. The parameters for clinical outcome were Constant Score (CS) and Korean Shoulder Score (KSS). RESULTS: The number of cases was 10 in group 1 and 9 in group 2. The strength of FE and Abd were significantly higher in group 1 (p<0.001 and p<0.001, respectively), and the strength of ER was not different significantly between two groups (p=0.065). For the clinical outcome, both CS and KSS were higher in group 1 (p=0.002 and p=0.002, respectively). The number of patients in group A was 11, and group B was 8. Although there was not a significant difference in terms of FE and Abd between group A and B (p=0.091, p=0.238), ER was significantly higher in group A (p=0.012). We did not find a significant difference in the clinical scores (CS, p=0.177 and KSS, p=0.238). CONCLUSIONS: These findings suggest the importance of a preoperative evaluation of the fatty degeneration of deltoid and teres minor muscles for predicting postoperative strength and clinical outcome.

BACKGROUND: Some research viewed that effective dietary therapy was enough to control proper blood glucose level, but in the most patient, dietary therapy was not practiced and the most difficult part of managing their diabetes. The purpose of this research study was to investigate dietary practice adherence and perceived barriers among the elderly diabetes. METHODS: The survey was mailed to 852 persons with diabetes member via diabetic educator of 156 hospitals or clinics and 24 health centers. Questionnaire had background information of patients, meal regularity, food intake as a dietary practice adherence, barriers of 36 items which have 3 areas such as motive/attitude, knowledge, authority/resource. We asked the person with diabetes to rate barrier to dietary practice adherence. 432 questionnaire were returned the response. we selected 69 persons who were over 65 year old. RESULTS: 1) meal regularity was more satisfactory than food intake. 2) deficit of meal regularity were evening snack and resonable spacing between evening meal and evening snack. 3) deficit of food intake was serving of milk. 4) main barrier to dietary practice adherence was that of knowledge. CONCLUSION: For practice effectively dietary therapy to elderly diabetes, individual consultation or small group education must be pursued and more easily educational skills should be required.

For the evaluation of children with urinary tract infection, the effective diagnostic approach with appropriate imaging studies may be one of the most important process. But there is no definitely standardized method to evaluate these children. The author analysed the radiologic findings on 88 consecutive children with recurrent urinary tract infection to investigate the diagnostic efficacy of abdominal ultrasonography compared to conventional excretory urography and determine logical sequence of uroradiologic study in children with urinary tract infection. The results were as follows: 1 Of all the children studied, there were 37 cases of vesicoureteral reflux (VUR) with or without another urologic abnormalities such as posterior urethral valve and double collecting system, 32 cases of ureteropelvic junction obstruction (UPJ obstruction) and 1 case of multicystic kidney. 2. All cases with UPJ obstruction and multicystic kidney were diagnosed with abdominal ultrasonography. But excretory urography did not detect 2 cases of mild UPJ obstruction due to intermittent hydronephrosis 3. Of 37 cases with VUR, 3 cases were not detected with abdominal ultrasonography and 5 cases were not detected with excretory urography 4. Of all the cases studied, 18 cases did not have any anatomical abnormalities. In these cases, abnormal findings on excretory urography and ultrasonography were detected in 2 and 3 cases, respectively 5. In the evaluation of anatomical abnormalities in the patient of recurrent UTI, combined radiologic study of ultrasonography and voiding cystourethrography has the same efficacy as excretory urography and voiding cystourethrography. These results suggest that abdominal ultrasonography may be more effective than excretory urography in the evaluation of children with urinary tract infection. And both ultrasonography and excretory urography are relatively insensitive for detecting reflux and its sequel. So in the evaluation of children with urinary tract infection, voiding cystourethrography and ultrasonography should be performed initially. And excretory urography could be performed for selected cases.

It has been postulated that programmed cell death via apoptosis may be critical for remodelling of glomeruli after inflammatory injury. To understand the regulatory mechanism of apoptosis in experimental crescentic glomerulonephritis (CGN), we examined the MIB-1 score (proliferation index, PI) and apoptotic index during the progression of experimental CGN to end-stage renal failure. CGN was induced in New Zealand White rabbits by administration of guinea pig anti-GBM IgG after sensitization with guinea pig IgG and their kidneys were analyzed for the development of crescents through sequential renal biopsies. Serum creatinine levels progressively increased in a time course until day 45. The PI in glomeruli, tubular epithelial cells, and interstitium progressively increased during the progression of experimental CGN. The mean numbers of MIB-1 positive intraglomerular nuclei (PI) were significantly correlated with degrees of crescent formation and the numbers of apoptotic cells in the glomeruli, tubules, and interstitium. Significant apoptosis was present from day 1 (15.8 10.16 cells/glomerular cross section) and increased in number with the proliferative lesions as glomerular inflammation continued. Moreover, apoptosis increased during the resolution of the glomerular inflammation, and many apoptotic cells were present in the sclerotic lesions in day 17 (18.6 12.99 cells/glomerular cross section). As glomerular inflammation subsided, cellular crescents progressed to fibrous crescents with a reduction of cellularity by day 45. On day 45, the glomerular PI and the numbers of apoptotic cells were markedly decreased. The correlations found in CGN between the creatinine level and the percentage of crescents, between the percentage of crescent and PI, and between the PI and number of apoptotic cells support the hypothesis that there is a change in the glomerular and tubulo-interstitial apoptosis under pathologic conditions. These findings indicate that apoptosis plays an essential role in the resolution of intra- and extraglomerular inflammation and in the elimination of glomerular cells within the sclerotic regions for progressive CGN. The regulation of the apoptotic phenomenon and increased PI during CGN may be important in the progression of glomerular inflammation and the development of pathologic glomerular sclerosis.
