BACKGROUND: Kirschner's wire (K-wire) transfixation and locking hook plate fixation techniques are widely used in the treatment of acute acromioclavicular joint (ACJ) dislocation. The purpose of this study was to compare the clinical and radiologic outcomes between K-wires transfixation and a locking hook plate fixation technique. METHODS: Seventy-seven patients with acute ACJ dislocation managed with K-wire (56 shoulders) and locking hook plate (21 shoulders) were enrolled for this study. The mean follow-up period was 61 months. RESULTS: At the last follow-up, the shoulder rating scale of the University of California at Los Angeles (UCLA) was higher in patients treated with locking hook plate than with K-wires (33.2 +/- 2.7 vs. 31.3 +/- 3.4, p=0.009). In radiologic assessments, coracoclavicular distance (CCD) (7.9 mm vs. 7.7 mm, p=0.269) and acromioclavicular distance (ACD) (3.0 mm vs. 1.9 mm, p=0.082) were not statistically different from contralateral unaffected shoulder in locking hook plate fixation group, but acromioclavicular interval (ACI) was significant difference. However, there were significant differences in ACI, CCD, and ACD in K-wire fixation group (p<0.001). Eleven complications (20%) occurred in K-wire transfixation group and 2 subacromial erosions on computed tomography scan occurred in locking hook plate fixation group. CONCLUSIONS: ACJ stabilization was achieved in acute ACJ dislocations treated with K-wires or locking hook plates. Locking hook plate can provide higher UCLA shoulder score than K-wire and maintain CCD, and ACD without ligament reconstruction. K-wire transfixation technique resulted in a higher complication rate than locking hook plate.

This is a clinical study of 30 cases of congenital malformation of ileum at Severance hospital from 1966 to 1975. They were confirmed after operation and the results were summarized as follows; 1. Total number of patients was 30 cases including 25 males 5 females. Among them 20 cases were included at pediatric agr from birth to 15 years of age. The most frequent occurrence was within 1 month of age with 11 cases. 2. Confirmed diagnesis after operation were 3 cases of ileal duplication,3 cases of ileal stenosis, 2 cases of ileal atresia, 1 cases of ileal hypoplasia, and 21 cases of Meckel's diverticulum. 3. Except for Meckel's diverticuium all the patients were studied which simple abdominal X-ray, which revealed complete and partial intestinal obstruction. Among them 4 cases were found microeolon and narrowing of distal 1 cases of ileum at 1 cases of ileal atresia and 2 cases. 4. After operation, 26 of 30 cases were recovered but 3 cases (atsesia 1, stenosis 1, and hypoplasia 1) were discharged with complications. And 1 case of multiple ileal stencelsdied of sepsis and wound infection.

A case of cryptococal hepatitis in a 4-year-old girl was presented with a brief review of the literature. She was admitted with the chief complaints of jaundice, abdominal pain, and semicomatose mental state. Treatment was started including dexamethasone under impression of fulminant hepatitis. During treatment massive G-I bleeding appeared which required eleven pints of blood and 20 days for control. Upper G-I series revealed duodenal ucer. And explolparotomy was performed because of free air in the peritoneum. Operative liver biopsy done at that time revealed many cryptococci in the biopsy tissue. Therefore we treated her with-5-fluorocytosine and the result was good. Follow-up of her for a year and half revealed that she was in here good general condition. Therefore we consider that secondary change in liver such as cirrhosis has not yet occurred in her.

BACKGROUND/AIMS: The efficacy of standard triple therapy (STT) in treating Helicobacter pylori infection has decreased. Many investigators have attempted to increase the eradication rate. We investigated the outcomes of concomitant therapy (CT) and STT combined with probiotics (STP) as a first-line treatment for H. pylori infection. METHODS: We reviewed the medical records of 361 patients who received either STP (n=286) or CT (n=75). The STP group received STT combined with a probiotic preparation for 1 week. The CT group received STT and metronidazole for 1 week. RESULTS: The intention-to-treat and per-protocol eradication rates were 83.6% (95% confidence interval [CI], 79.0 to 87.7) and 87.1% (95% CI, 81.2 to 89.7) in the STP group and 86.7% (95% CI, 78.7 to 93.3) and 91.4% (95% CI, 83.6 to 97.1) in the CT group (p=0.512 and p=0.324), respectively. The frequency of adverse effects was higher in the CT group (28.2%) than in the STP group (12.8%) (p=0.002). CONCLUSIONS: STP and CT are encouragingly efficacious as first-line treatments for H. pylori infection. Therefore, adding probiotics to STT may be a feasible option to avoid side effects.

Purpose: Cone beam computed tomography (CBCT) is widely used to evaluate the temporomandibular joint (TMJ). For the three-dimensional (3D) assessment of the TMJ, segmentation of the mandibular condyle and articular fossa is essential. This study aimed to perform deep learning-based 3D segmentation of the mandibular condyle on CBCT images and evaluate the performance of the segmentation. Methods: CBCT scan data from 99 patients (mean age: 53.3±19.2 years) diagnosed with TMJ disorders were analyzed. From the CBCT images, sagittal, coronal, and axial planes showing the mandibular condyle were selected and combined to form two-dimensional (2D) images. The U-Net deep learning model was used to exclusively segment the mandibular condyle area from the 2D images. From these results, 3D images of the mandibular condyle were reconstructed. Accuracy, precision, recall, and the Dice coefficient were calculated to appraise segmentation performance in each plane. Results: The average Dice coefficient was 0.92 for the coronal and axial planes and 0.82 for the sagittal plane. The CBCT image-based segmentation performance of the mandibular condyle in the coronal and axial planes exceeded that in the sagittal plane. The sharpness and uniformity of the 2D images affected segmentation performance, with segmentation errors more likely occurring in non-uniform images. Certain segmentation errors were corrected through software processing. Finally, the segmented mandibular condyle images were applied to the CBCT data to reconstruct a 3D TMJ model. Conclusions Mandibular condyle 3D segmentation on CBCT images using U-Net may help evaluate and diagnose TMJ disorders. The proposed segmentation method may assist clinicians in efficiently analyzing CBCT images, particularly in cases involving anatomical abnormalities.

Collagenous colitis is an uncommon condition charaeterized clinically by diarrhea and weight loss and histologically by thickening of the subepithelial collagen band with chromic inflammation. Laboratory tests of blood, urine and stool, and colonscopic findings are usually normal. The etiology of collagenous colitis is unknown. We report a case of collagenous colitis improved after treatment with sulfasalazine with review of literatures.

Behcet's disease is characterized by recurrent orogenital ulcers and ocular and cutaneous inflammatory lesions. It is a multisystem disorder affecting the skin, mucous membrane, eyes, joints, CNS and blood vessels. The vascular involvements consist of thrombophlebitis, arterial occlusion and arterial aneurysm. Rupture of large artery aneurysm is the leading cause of death in patients with Behcet's disease and surgical treatment is necessary. But, surgical treatment is often difficult and may lead to formation of further false aneurysms at the site of vascular anastomosis. Endovascular stent-graft placement emerged as an alternative treatment that is less invasive with a lower risk. We report a case of the aneurysm of right common iliac artery associated with Behcet's disease. Percutaneous stent-graft placement was attempted and successfully controlled aneurysmal manifestations.

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

OBJECTIVES:It was reported that fatigue was the seventh most common symptom in primary care and 24% of the general adult population had fatigue lasting 2 weeks or longer in the united states. No medical cause was found in 59% to 64% of those persons. Chronic fatigue syndrome is chracterized by debilitating fatigue of at least 6 months duration accompanied by other symptoms such as fever, pharyngitis, painful lymph nodes, headache, myalgia, sleep disturbances, neurocognitive complaints, and depression. Idiopathic chronic fatigue is defined as clinically evaluated, unexplained chronic fatigue that fails to meet criteria for the chronic fatigue syndrome. The objectives of this study were to determine the prevalence of idiopathic chronic fatigue and chronic fatigue syndrome (CFS) in Korea and to analysis the symptoms of those patients. METHODS: Five hundred thirty persons who visited Korea university hospital health management center between March 1998 and June 1998 were participated in the study. The questionnaire made according to the Centers for Disease Control and Prevention criteria was administerd and patients with idiopathic chronic fatigue and chronic fatigue syndrome were diagnosed by this questionnaire, physical examination and laboratory tests. RESULTS: Ten persons(1.9%) met the criteria for chronic fatigue syndrome. and 115 persons (21.7%) met the criteria for idiopathic chronic fatigue. The symptoms in patients with chronic fatigue syndrome were memory loss or forgetfullness(90%), sore throat(20%), painful lymph node(30%), myalgia(80%), multiple arthralgia(20%), headache(50%), unrefreshing sleep(100%), postexertional malaise(90%). CONCLUSION: Persons who met the criteria for chronic fatigue syndrome were found in 1.9%. The incidence of chronic fatigue syndrome in our study was high, compared with previous studies.
