Acute suppurative thyroiditis is uncommon in children. The relative rarity of thyroid infection is thought to reflect its complete fibrous encapsulation, generous vascular and lymphatic supply and high local iodine level. The bacterial involvement include the normal oropharyngeal microflora, and broad spectrum antibiotic therapy including anaerobic coverage should be utilized initially. We have experienced three cases of acute suppurative throiditis. All of them had painfull swelling on anterior cervical area and diagnosed by clinical and radiological features. Since two of them occured repeatedly, we report with brief review of literatures.

Hyperglycemia is a well-recognized side effect of L-asparaginase in remission induction therapy of acute lymphocytic leukemia. Since hyperglycemia has preceded fatal diabetic ketoacidosis or hyperosmotic nonketotic coma in some patients, early detection and treatment of this complication are important. We determined retrospectively the risk of hyperglycemia in 117 patients with leukemia who had received L-asparaginase (& prednisolone). The results were as follows: 1) Twenty (17%) of the 117 patients developed hyperglycemia. 2) Of 47 female patients, 13 developed hyperglycemia, contrast with only 7 of 70 male patients(P<0.05). 3) All 2 obese patients developed hyperglycemia, contrast with 18 of 115 non obese patients (P<0.05). 4) Of 16 patients with a history of previous administration of L-asparaginase 6 (42%) developed hyperglycemia, contrast with only 14 (11%) of the remaining 101 patients (P<0.05). 5) Of the remaining factors analyzed-age, leukocyte counts, family history, dose of L-asparaginase-non had a statistically important influence on the development of hyperglycemia. 6) The mean glucose concentration at onset was 355+/-197.5mg/dl in patient who developed hyperglycemia with peak concentration of 404+/-253.6mg/dl. Hyperglycemia developed between 3 to 20 days after administration of L-asparaginase, and the duration of hyperglycemia was 6.90+/-5.54 days. Since hyperglycemia developed inevitably in a certain proportion of patients given L-asparaginase, we recommend blood glucose monitoring in patients with the risk factors.

Clinical study was done on 119 patients with atrial fibrillation in the aspect of underlying diseases, particulary. The results were as follow : 1) In the underlying diseases of atrial finbrillation, rheumatic heart disease, hepertension and ischemic heart disease were common, which occupied 27.8%, 22.7% and and 15.1%, respectly. No apparent underlying disease was found in 21.0%, but in the transient atrial fibrillation, no apparent underlying disease in 42.9%. 2) There were no significant correlations between the ventricular rate, amplitude of f wave and underlying diseases of atrial fibrillation. 3) Complications were found in 29.4% of all cases, such as congestive heart failure(22.7%), embolism(6.7%). Otherwise, atrial fibrillation without underying cardiovascular diseases, congestive heart failure was found only(7.7%).

Primary localized amyloidosis of the urinary tract is very rare disease. A 72-year-old man, with a history of urethral injury, had a stricture of the anterior urethra about 6cm in length. A segmental resection of urethra and urethroplasty, with penile skin flap, was performed. The resected urethral segment was diagnosed as urethral amyloidosis. There was no involvement of amyloidosis oin the other organs (heart, gastrointestinal system, joint, kidney, skin etc) and no underlying disease (multiple myelomas, rheumatism, cancer, chronic inflammation etc). Also, a 75-year-old woman, with a history of intermittent gross hematuria, had a stricture of the lower ureter. During diagnostic ureteroscopy, there was an irregular mucosal change of her lower ureter. An intraoperative biopsy showed ureteral amyloidosis. Here, we report on these two cases of primary amyloidosis of the urinary tract.

PURPOSE: To study the effects of growth hormone(GH) treatment on glucose metabolism and insulin resistance in children with idiopathic short stature(ISS). METHODS: Glucose and insulin concentrations were measured during oral glucose tolerance test (OGTT) before and after GH treatment(0.6-0.7 IU/kg/week) in 20 patients with ISS. Insulin resistance was assessed by homeostasis model assessment(HOMA). RESULTS: During OGTT, the mean blood glucose level did not show any significant changes after GH treatment. However, mean blood insulin levels of fasting and 30 minutes of OGTT showed significant increases after GH treatment, accompanying significant increases of insulin resistance. There was no difference in change of glucose, insulin levels and insulin resistance before and after GH treatment between two groups of body mass indices(BMI) of 25< and >25. There also was no significant difference between two groups of with and without family histories of diabetes mellitus (DM). There was no case of newly developed impaired glucose tolerance, fasting glucose tolerance, nor newly developed DM. CONCLUSION: GH treatment with doses of 0.6-0.7 IU/kg/week for mean 9.6 months in patients with ISS did not show any significant changes in blood glucose levels during OGTT. However, GH treatments induced considerably higher fasting insulin levels compared to pretreatment, resulting in statistically higher insulin resistance. Higher BMI and family history of DM did not induce any significant changes in glucose, insulin level and insulin resistance after GH treatment than the other groups.

Mechanical thrombectomy using a stent retriever is a widely-used technique for recanalizing occluded cerebral arteries in acute ischemic stroke. Although rare, inadvertent stent detachment has primarily been reported with earlier stent retriever designs. We present 2 cases of inadvertent stent detachment with the pRESET stent. In the first case, an elderly patient presented with right middle cerebral artery occlusion and experienced stent detachment during the second retrieval. Despite this, successful recanalization was achieved through balloon angioplasty. In the second case, an elderly patient experienced stent detachment after the third retrieval, and recanalization of the M1 segment was unsuccessful due to the inability to pass the microcatheter. The first patient had a modified Rankin scale (mRS) score of 3, while the second had a poor prognosis with an mRS score of 5. These cases highlight that inadvertent stent detachment can impact outcomes, and balloon angioplasty may serve as a useful salvage therapy.

This study was done to characterize the natural course of C-peptide levels in patients with type 1 diabetes and identify distinguishing characters among patients with lower rates of C-peptide decline. A sample of 95 children with type 1 diabetes was analyzed to retrospectively track serum levels of C-peptide, HbA1c, weight, BMI, and diabetic complications for the 15 yr after diagnosis. The clinical characteristics were compared between the patients with low and high C-peptide levels, respectively. The average C-peptide level among all patients was significantly reduced five years after diagnosis (P < 0.001). The incidence of diabetic ketoacidosis was significantly lower among the patients with high levels of C-peptide (P = 0.038). The body weight and BMI standard deviation scores (SDS) 15 yr after diagnosis were significantly higher among the patients with low C-peptide levels (weight SDS, P = 0.012; BMI SDS, P = 0.044). In conclusion, C-peptide level was significantly decreased after 5 yr from diagnosis. Type 1 diabetes patients whose beta-cell functions were preserved might have low incidence of diabetic ketoacidosis. The declines of C-peptide level after diagnosis in type 1 diabetes may be associated with changes of body weight and BMI.

Recently limb sparing surgery is accepted as an alternative method in the management of muskuloskeletal tumors of the extremity without undue compromise to the patient s life. But the limb sparing procedure results in large osseous and soft tissue defects. To fill these defect, several options have been used such as tumor prosthesis, temporary spacer with cementation, allograft, and autograft(fresh, autoclaved, low heat treated, and extracorporeal irradiated). To identify the indica- tions ot' individual option, we studied 66 cases of musuloskeletal tumors of extremity which were treated with wide or marginal resection and reconstructive surgery from June, 1990 to June, 1997, in which 48 cases were osteosarcomas, 3 chondrosarcomas, 2 synovial sarcomas. I liposarcoma, 1 giant cell tumor, I malignant lymphoma, and 10 metastatic bone tumors. The location of the lesion were distal femur in 24, proximal tibia in 24, proximal femur in 9, proximal humerus in 6, tibial midshaft in 1. distal radius in 1, and calcaneus in 1. In Enneking stages about primary bone tumors 6 cases were IIA, 42 IIB, and 8 III. We reconstructed the osseous defect with tumor prosthesis in 22 cases, temporary spacer in 9(later, 4 cases was changed to tumor prosthesis for staged operation), allograft in 25, and autograft in 14(low heat treated in 2, irradiated in 12). Total functional result by Enneking system was 71.5% . 80.8% with tumor prosthesis, 50.5% with temporary spacer, 70% with allograft, 75.3% with autograft. Infections were occurred in 18% of the patients treated with tumor prosthesis, 34% with allograft, 0% with temporary spacer or low heated autograft, and 18% with irradiated autograft. Delayed union or nonunion was occurred in l5% of the patients treated with allograft, 40% with autograft. There were 2 cases of metal failure and 2 cases of graft fracture using autograft. In conclusion, we propose that the indication of the tumor prosthesis is for the skeletally matured patient, patient with high-grade malignant tumor, older patients, and patient who have limited life expectancy. The reconstruction with allograft have several advantages for the patients with henign bone tumor and locally aggressive or low-grade malignant tumor. The temporary spacer may be used as staged operations for the skeletally immature patient and patient who have an extreme hone and soft tissue defects after limb sparing operation. The recycling autograft may be applied to the patients at any age with minimal bony involvement of tumor. The low heat treated autograft may be useful in the patients requiring intercalary reconstruction, and the irradiated autograft may he useful in the patients with periarticular involvement.
