The purpose of this study was examine the general characteristics of relapsed pulmonary tuberculous patients (i.e. age, sex, weight, occupation, previous forms of treatment, drug sensitivity, and the frequency of relapse) in order to improve future treatments of tuberculosis as well as to perpetuate health education. The data was obtained from the medical records of 186 relapsed pulmonary tuberculosis patients who were registered for treatment at various public health offices in Seoul during the year of 1994. The major findings obtained from the study were as follows; 1) The male to female ratio of relapsed pulmonary tuberculous patients was about 7:3, more specifically 23.7% of the men and 30.9% of the women were between 20 and 29 years of age. 2) Comparing initial less aggravated states to relapsed states, patients with minimal X-ray findings later proved moderately advanced X-ray findings. Furthermore, patients with negative sputum AFB findings later proved positive sputum AFB findings. 3) Of the 186 patients studied, 91.9% suffered, relapse and 8.1% suffered 2 or more relapses. Of the patients who suffered at least 1 relapse, 54.8% received short-term treatment, 26.9% received long-term treatment, and 18.3% received treatment of an unknown during their initial tuberculosis treatment periods. 4) fifty five point four percent of the patients had no reaction to the drug treatment(not available), 25.9% of the patients had sensitive reaction to the drug treatment, 18.7% of the patients had resistant reaction to the- drug treatment. Drug resistance was higher in patients that exhibited positive X-ray findings as well as in patients that exhibited positive sputum AFB findings. furthermore, patients receiving treatment of an unknown nature(35.5%) exhibited higher drug resistance than those receiving short-term treatment(13.6%) and long-term treatment(17.0%). 5) Of the 160 patients who suffered relapses, 8.8% suffered a relapse within 1 year after treatment and 91.2% suffered a relapse at least 1 year after treatment. Furthermore, our study showed that women, under 30, who received short-term treatment and encounterd complications during their primary treatment suffered relapses faster than any other groups studied. In addition, minimal X-ray findings and sputum AFB findings were not correlated to the time relapse occured. Therefore, the seater efforts are needed to prevent relapsed pulmonary tuberculosis.

An 8-month-old domestic shorthair cat presented with decreased activity and anorexia. Diagnostic imaging revealed cranial mediastinal mass and enlarged mesenteric lymph nodes. Fine needle aspirates showed a marked increase in malignant lymphocytes. Multicentric lymphoma (stage V-b) was diagnosed. The cat treated with COP protocol chemotherapy, and complete remission was induced. CNS relapse developed 314 days after the initiation of chemotherapy. Treatment with rescue protocol greatly reduced the clinical signs for a short period. The cat was in partial remission for 33 days and overall survival time was 383 days. Multicentric T-cell lymphoma with brain involvement was confirmed after necropsy by histopathology and immunohistochemistry.

The purpose of the current report is to present 6-year long-term stability and 10-year follow-up data for an adult patient who was treated with a tongue elevator for relapsed anterior open-bite. The 19-year-old male patient presented with the chief complaint of difficulty in chewing his food. Collectively, clinical and radiographic examinations revealed an anterior open-bite, low tongue posture, and tongue-tie. The patient opted for orthodontic treatment alone, without any surgical procedure. A lingual frenectomy was recommended to avoid the risk of relapse, but the patient declined because he was not experiencing tongue discomfort. Initial treatment of the anterior open-bite with molar intrusion and tongue exercises was successful, but relapse occurred during the retention period. A tongue elevator was used for retreatment, because the approach was minimally invasive and suited the patient's requirements regarding discomfort, cost, and time. The appliance changed the tongue posture and generated an altered tongue force, which ultimately resulted in intrusive dentoalveolar effects, and a subsequent counterclockwise rotation of the mandible. The results showed long-term stability and were maintained for six years through continual use of the tongue elevator. The results of this case indicated that a tongue elevator could be used not only as an alternative treatment for open-bite, but also as an active retainer.

Purpose : Focal segmental glomerulosclerosis(FSGS) is known to have a poor prognosis and a poor response to treatment. We performed a combination therapy of plasmapheresis, steroid pulse and immunoglobulin in 4 patients with relapsed steroid dependent(SD) or steroid resistant(SR) FSGS after steroid pulse therapy. Materials and Methods : 8 cycles of plasmapheresis were performed in 4 patients with biopsy proven FSGS who had relapsed after steroid pulse therapy from March 1988 to July 2002. Clinical findings and treatment courses were reviewed retrospectively. Results : Among the 4 patients, there were 3 males and 1 female. After 8 cycles of plasmapheresis, clinical remissions were obtained. Two of the four patients had two relapses and received 2 more cycles of plasmapheresis which resulted in remissions. One of these patients had two further relapses and was treated with oral steroid resulting in clinical remission. Three patients have maintained normal serum creatinine level and glomerular filtration rates during the follow-up period of 10 years, and the other 1 patient for 5 months. Conclusion : A combination therapy of plasmapheresis, steroid pulse and immunoglobulin led to a complete remission in patients with FSGS who were SD or SR and was effective in maintaining normal renal function.

Purpose: The ischial area is by far the most common site of pressure sores found in wheel chair bound paraplegic patients, because greatest pressure is exerted from the body on this area in a sitting position. Even after a series of successful pressure sore treatments, the site is very prone to relapse by the simplest ordinary tasks of everyday life. Therefore, it is crucial to preserve the main pedicle during primary surgery. Various surgical procedures employed to treat pressure sores such as myocutaneous flap and perforator flap have been introduced. After introduction of ischial sore treatment using the inferior gluteal artery perforator (IGAP) has been made, the authors experienced favorable clinical results of patients who have undergone IGAP flap procedure in a three year time period. Methods: A total of 17 patients received IGAP flap surgery in our hospital from January 2003 to May 2006, among which 14 of them being males and 3 females. Surgery was performed on the same site again in 6(35%) patients who had originally relapsed after receiving the conventional method of pressure sore surgery. Patients' average age was 49.4(27-71) years old. Most of the patients were paraplegic(11 cases, 65%) and others were either quadriplegic(4 cases, 23%) or ambulatory(2 cases, 12%). Based on hospital records and clinical photographs, we have attempted to assess the feasibility and practicability of the IGAP flap procedure through comparative analysis of several parameters: size of defective area, treatment modalities, occurrence of relapses, complications, and postoperative treatments. Results: The average follow-up duration of 17 subjects was 25.4 months(5-42 months). All flaps survived without any necrosis. Six cases were relapsed cases from conventional surgical procedures. All of them healed well during our follow-up study. Postoperative complications such as wound dehiscence and fistula developed in some subjects, but all were well healed through secondary treatment. A total of 2 cases relapsed after surgery. Conclusion: The inferior gluteal artery perforator flap is an effective method that can be primarily applied in replacement to the conventional ischial pressure sore reconstructive surgery owing to its many advantages: ability to preserve peripheral muscle tissue, numerous possible flap designs, relatively good durability, and the low donor site morbidity rate.

The period from .1959 to 1976, authors experienced 13 cases of thymoma at the Department of Thoracic and Cardiovascular Surgery in National Medical Center. Ten patients were male, and 3 patients were female.Main complaints were cough 76.9%, dyspnea, 69.2%, chest pain 61.6%, myasthenia gravis 23.1 % and S.V.S 23.1%. All of them located anterior mediastinum. 7 cases were benign and 6 cases were malignant. Lymphocytic type was 5 cases, epithelial type 3 case,spindle cell type 1 case, mixed type 2 cases, cystic type 1 case and seminomatous type 1 case. All cases were surgically approached but in malignant cases, only 1 case was palliatively removed and followed radiation therapy. 4 cases were made only biopsy, among them, obstained good response with radiation therapy in seminomatous type case. In benign cases, excellent result was obtained but 2 cases which were combined myasthenia gravis were relapsed the symptoms.

A 5-year-old neutered female Dachshund dog presented with a 3-month history of hyperthermia, skin lesions, and shifting lameness. Based on physical examination, blood tests, urinalysis, and radiographs, the dog was diagnosed with systemic lupus erythematosus. Clinical signs improved after administration of prednisolone and cyclosporine but relapsed after the prednisolone was reduced due to side effects. Oral levamisole was commenced and the other immunosuppressants were tapered over a period of 2 months and then stopped. Levamisole was retained as the sole therapy for an additional 2 months. Six months after discontinuation of all treatment, the patient remained in remission.

To find out the differences between periodontal ligament cells (PDL cells) and gingival fibroblast cells (GFB cells), alkaline phosphatase, a marker enzyme for osteoblast, was used to measure the activities and $^{45}CaCl_2$ isotope was used to find out cellular and release of $^{45}Ca$, a requisite for bone formation,. PDL cells and GFB cells from 1 to 5 passages were also measured in alkaline phosphatase activity assay. By the use of above methods, followings were concluded that the PDL cells and the GFB cells have characteristics that are different from each other. In that PDL cells showed large amount of calcium uptake and large amount of calcium release in initial stage, they seem to possess characteristics which are similar to osteoblast-like cells. 1. The PDL cells, in contrast to the gingival fibroblast, showed exceedingly high alkaline phosphatase activity which was highest at the second passage, decreasing thereon. But gingival fibroblasts cells showed no distinct differences in alkaline phosphatase activity as the passage were elapsed. 2. For both PDL cells and GF cells, the $^{45}Ca$ uptake was greatest at 2 hours period. The PDL cells showed higher measuring than GFB cells through out the whole time period. 3. Whereas the GFB cells showed slow increase of $^{45}Ca$ release as time relapsed, the PDL cells showed rapid increase of $^{45}Ca$ release.

Objective: The purpose of this study was to evaluate the effectiveness of middle meningeal artery embolization (MMAE) in elderly high-risk patients with symptomatic chronic subdural hematoma (CSDH) in terms of reduction in hematoma volume and recurrence rate. Methods: We retrospectively reviewed data prospectively collected from nine patients who underwent 13 MMAE for CSDH between June 2017 and May 2022. The volume of the subdural hematoma was measured using a computer-aided volumetric analysis program. Hematoma volume changes during the follow-up period were analyzed and clinical outcomes were evaluated. Results: The mean follow-up period was 160 days (range, 46-311 days). All procedures were technically successful and there were no procedure-related complications. Of the 13 MMAE, 84% (11 out of 13 hemispheres) showed mean 88% of reduction on follow-up volumetric study with eight cases of complete resolution. There was one refractory case with MMAE which had been performed multiple burr-hole trephinations, for which treatment was completed by craniotomy and meticulous resection of multiple pseudomembranes. There was no recurrent case during the follow-up period, except for refractory case. Conclusions: MMAE for CSDH in selected high-risk elderly patients and relapsed patients might be effective. Despite the small cohort, our findings showed a high rate of complete resolution with no complications. Further prospective randomized trials are warranted to evaluate its usefulness as a primary treatment option for CSDH.

Nephrotic syndrome (NS) is a common chronic disease in children; in 90 percent of cases, the condition is primary (idiopathic). Toxic nephropathy can be induced by herbal medicines, and is mainly manifested as tubulointerstitial nephritis and rarely, as glomerulopathy. Here in, we describe two cases of steroid-sensitive NS, which developed after the patients received herbal medicines. A 5-year-old boy and an 8-year-old girl were separately admitted within a short time period with acute onset of generalized edema, proteinuria, hypoalbuminemia, and hypercholesterolemia. Each patient had previously taken herbal medicine, which had been prescribed by different oriental medical clinics for different conditions. The patients were diagnosed with herbal medicine-induced NS and were treated empirically by a standard steroid therapy, with subsequent resolution of their NS. One patient relapsed, but her NS again responded to steroid therapy. We described two unusual cases of prototypical pediatric, steroid-sensitive NS, which was presumed to be minimal-change disease that developed after the administration of herbal medicines. We also reviewed the literature.
