Radiolucent Pure Matrix Stones on Computed Tomography Scan, Arising in Patient with Type I Diabetes and Chronic Kidney Disease: A Case Report / 가정의학회지

Kidney matrix stones are a rare form of calculi, which are challenging to diagnose. Matrix stones consist of a proteinaceous material which has a radiolucent appearance that might be overlooked on imaging. Recently, endourological intervention has been the standard treatment method for matrix stones. We report a case of urinary matrix stones in a patient with type 1 diabetes mellitus and chronic kidney disease, in whom the stones formed into a pure matrix and were not visualized in the computed tomography scan. The stones were found after additional work-up, and they were managed using a transureteral stone basket, not through endourological intervention.

Regression of a Mucosa-Associated Lymphoid Tissue Lymphoma of the Urinary Bladder After Helicobacter pylori Eradication Therapy in an Elderly Patient

Primary low-grade lymphoma of the mucosa-associated lymphoid tissue (MALT) type lymphoma of the bladder is rare. A relationship between MALT lymphoma of the urinary bladder and chronic cystitis has been proposed by some reports. Additionally a relationship between MALT lymphoma of the urinary bladder and Helicobacter pylori has been reported. Here we present a case of regression of urinary bladder MALT lymphoma after antibiotic therapy, using H. pylori eradication protocol in an elderly patient, who had a high risk of treatment related mortality in curative systemic chemotherapy. The patient is a 74-year-old woman who had a history of chronic cystitis. She was diagnosed with stage IIA primary MALT lymphoma of the urinary bladder and was treated with H. pylori eradication triple therapy for 2 weeks. After 2 months, there was a marked regression of the bladder MALT lymphoma lesion in a computed tomography scan of the abdomen.

Four Cases of Carbapenem-Resistant Enterobacteriaceae Infection from January to March in 2014 / 가정의학회지

Infection with carbapenem-resistant Enterobacteriaceae (CRE) and other multidrug resistant bacteria has increased rapidly in Korea. The Korea Centers for Disease Control and Prevention reported 1,609 cases of CRE infection in the country in 2013. The risk factors for CRE infection include history of treatment with antibiotics such as cephalosporins or carbapenem, trauma, diabetes, cancer, and history of ventilator support. Herein, we report four cases of CRE infection seen during a 3-month period in our hospital in 2014. CRE infection is associated with a high mortality rate of 30% to 50%, even with combination antibiotic therapy. Prevention of CRE infection in hospital settings is fundamental to controlling its transmission. Key preventive measures include, contact precautions, hand hygiene, education of healthcare personnel, screening for CRE when indicated, and exercising discretion in prescribing carbapenem or cephalosporins.

Intramedullary Ependymoma in the Spinal Cord: A Report of Two Cases / 대한정형외과학회잡지

We have experienced two cases of the intramedullary ependymomas in the cervicothoracic and thoracolumbar spinal cord. The myelographic studies showed complete block or fusiform filling defect of the dye and they were treated by total laminectomy with excision of the tumor mass. The histological studies verified them ependymomas and the patients have shown good improvement of the neurological defecits in postoperative period.

Extension Contracture of Both Hip Joints Secondary to Congenital Fibrous Bands of Both Gluteus Maximus Muscles: Case Report / 대한정형외과학회잡지

Congenital fibrous bands may be found at the gluteus maximus, the gluteus medius,thequadriceqs,the triceps and the deltoideus muscles. Congenital fibrous bands of both gluteus maximus muscles are rare and cause extension contracture of the hip joints. We experienced a case of congenital fibrous bands of both gluteus maximus muscles associated with severe limited flexion of both hips. Almost full flexion of both hips was obtained by excision of the congenital fibrous bands.

A Study on the Myelography with Water Soluble Medium, Metrizamide (Amipaque) / 대한정형외과학회잡지

A total 48 cases of myelography using Metrizamide were performed between August 1981 and July 1983 at the department of Orthopedic Surgery, Kwangju Christian Hospital. Of these cases, H.N.P was 26, tuberculous spondylitis 16, spondylolisthesis 4, and multiple sclero-sis 2 cases. The advantages of this study were as folows: 1. Complications were minimal in most of the cases except a slight headache. 2. Large amount of infusion was possible. 3. Rootlet was clearly seen. 4. Removal of dye was not necessary. 5. It gave a good contrast for the radiologic study.

Curettage & Acrylic Cementation in Surgery of Giant Cell Tumors of Bone / 대한정형외과학회잡지

3 cases of giant cell tumor in the distal femur or upper tibia were treated by curettage and acrylic cement packing between October 1978 and May 1981. All were females. The postoperative courses were satisfactory with no recurrence or malignant change for periods of 16 months to 30 months. In one case, acrylic cement reinforced with tantalum wire was used because it is superior to acrylic cement alone in mechanical properties. The adventages of this method are: 1. The cautery effect of setting cement. 2. Avoidence of the need for large quantities of cancellous bone 3. The possibility of incorporating a prosthesis if the lesion is extensive. 4. Rapid mobilization. 5. Ease of early diagnosis of recurrence.

The use of Methylmethacrylate as an Adjunct in the Internal Fixation of metastatic Femoral Shaft Fracture / 대한정형외과학회잡지

This report deals with a 49-year-old male farmer who had a pathological fraeture. of the right femoral shaft due to metastatic carcinoma from the middle lobe of the right lung. The lesion of the femur was resected en-bloc and bone stabilization of the fractured bone was obtained by an intramedullary Kiintscher nail plus cement fixation. Two weeks later, a right middle and lower lobectomy was done. Microscopic examination of both specimens from right femur and lung revealed poorly differentiated squamous cell carcinoma. The postoperative course was satisfactory with no recurrence for period of 26 months.
