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.

Long-term treatment of cultured bovine adrenal medullary chromaffin (BAMC) cells with arachidonic acid $(100\;{\mu}M),$ angiotesnin II (100 nM), prostaglandin $E_2\;(PGE_2;\;10\;{\mu}M),$ veratridine $(2\;{\mu}M)$ or KCl (55 mM) for 24 hrs increased both norepinephrine and epinephrine levels in the supernatant. Pretreatment with staurosporine (10 nM), a protein kinase C (PKC) inhibitor, completely blocked increases of norepinephrine and epinephrine secretion induced by arachidonic acid, angiotensin II, $PGE_2,$ veratridine or KCl. In addition, K252a, another PKC inhibitor whose structure is similar to that of staurosporine, effectively attenuated both norepinephrine and epinephrine secretion induced by arachidonic acid. However, K252a did not affect the catecholamine secretion induced by angiotensin II, $PGE_2,$ veratridine or KCl. Our results suggest that staurosporine may inhibit long-term catecholamine secretion induced by various secretagogues in a mechanism other than inhibiting PKC signaling. Furthermore, long-term secretion of catecholamines induced by arachidonic acid may be dependent on PKC pathway.

Objectives: To identify the factors affecting long-term adherence to methylphenidate treatment in children with attention-deficit hyperactivity disorder (ADHD). Methods: A retrospective medical record review of 239 ADHD patients (mean age $9.3{\pm}2.6$ years, range 6.0-17.4 years) who had visited the child and adolescent psychiatry clinic at a university hospital, in Seoul, Korea from March 2005 to February 2008. Subjects were diagnosed as ADHD based on the criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders 4th edition, text revision version (DSM-IV-TR) and underwent neuropsychological tests including the continuous performance test (CPT). Treatment discontinuation was defined as the last prescription date when the medication possession rate (MPR) became less than 0.80. Subjects were divided into three groups and labeled as Group I, non-adherence without pharmacotherapy, Group II, non-adherence with short-term pharmacotherapy, and Group III, adherence with long-term pharmacotherapy. Results: Ninety (37.7%) patients were grouped as non-adherent (Groups I+II) and 149 (62.3%) as adherent (Group III). The adherence group exhibited lower intelligence, higher symptom severity, and a higher number of comorbid psychiatric disorders than controls. The use of stimulants was significantly associated with long-term adherence to treatment. Additionally, the duration of interval between the date of the first visit and the date of the first prescription was positively associated with long-term adherence. Conclusion: About two-thirds of patients diagnosed as ADHD adhered to the treatment six months after the first visit. With respect to patient evaluation and the development of treatment strategies, factors affecting early drop-out and longer follow-up must be considered.

The purpose of this study was the long-term clinical and radiological evaluation of conservatively treated condylar fractures in children. This study was therefore undertaken to analyze the long-term effects of treating condylar fractures in children with conservative therapy in order to resolve the controversial question of whether complete remodeling occurs in this age or, if not, whether it is more likely to be associated with certain types of fracture or with other factors. This study was based on a series of 11 consecutive children and adolescents, aged between 3 and 15 years, with fractures of the condylar process who had been treated with conservative therapy at the Department of Oral & Maxillofacial surgery, Inha University Hospital, Inchon, Korea. All patients underwent a clinical investigation with special emphasis on Temporomandibular joint function and facial asymmetry. The patients also underwent a radiologic investigation, focusing on fracture remodeling and symmetry of mandible. It consists of panoramic radiograph, PA & lateral cephalogram and 3-D CT. No patient described impaired temporomandibular joint(TMJ) function or pain on the affected side. 2 of 8 (25%) unilateral and 1 bilateral fractures show slight facial asymmetry. Despite apparently excellent recovery of function, there were marked remodeling changes evident on the CT scan. Such changes are not usually evident on panoramic radiograph. Radiologic investigation showed incomplete remodelling(54.5%) and asymmetry of the mandible (27.3%) in some patients. Conservative treatment of condyle fracture in children results in satisfactory long-term outcome of jaw function despite a relative high frequency of radiologically noted aberrations.

Objectives: This case report describes the effect of complex Korean medical treatment on the clinical symptoms of a patient with fibromyalgia syndrome (FMS). Methods: A 60-year-old female woman diagnosed with FMS in 2015 was prescribed Youngsunjaetong-em-hap-Sopunghwalhyeol-tang from 2 May 2023 to 20 June 2023 to reduce excessive sweating and widespread pain. With the same objective, acupuncture, moxibustion, and cupping treatment were administered from 23 May 2023 to 11 June 2023. Changes in excessive sweating and widespread pain were recorded 2 months post-treatment. Results: Treatment with Youngsunjaetong-em-hap-Sopunghwalhyeol-tang led to a considerable improvement in clinical symptoms after 2 months, especially excessive sweating and widespread pain compared to the baseline parameters of the first visit. In addition, no adverse effects, such as liver injury or decreased kidney function, were recorded during the herbal medicine treatment. Conclusion: This case report points to the use of complex Korean medical treatment as a therapeutic option for the management of FMS.

Objective : Meningiomas represent 18-20% of all intracranial tumors and have a 20-50% 10-year recurrence rate, despite aggressive surgery and irradiation. Hydroxyurea, an inhibitor of ribonucleotide reductase, is known to inhibit meningioma cells by induction of apoptosis. We report the long-term follow-up result of hydroxyurea therapy in the patients with recurrent meningiomas. Methods : Thirteen patients with recurrent WHO grade I or II meningioma were treated with hydroxyurea (1000 $mg/m^2/day$ orally divided twice per day) from June 1998 to February 2012. Nine female and 4 male, ranging in age from 32 to 83 years (median age 61.7 years), were included. Follow-up assessment included physical examination, computed tomography, and magnetic resonance imaging (MRI). Standard neuro-oncological response criteria (Macdonald criteria) were used to evaluate the follow-up MRI scans. The treatment was continued until there was objective disease progression or onset of unmanageable toxicity. Results : Ten of the 13 patients (76.9%) showed stable disease after treatment, with time to progression ranging from 8 to 128 months (median 72.4 months; 6 patients still accruing time). However, there was no complete response or partial response in any patients. Three patients had progressive disease after 88, 89, 36 months, respectively. There was no severe (Grade III-IV) blood systemic disorders and no episodes of non-hematological side effects. Conclusion : This study showed that hydroxyurea is a modestly active agent against recurrent meningiomas and can induce long-term stabilization of disease in some patients. We think that hydroxyurea treatment is well tolerated and convenient, and could be considered as an alternative treatment option in patients with recurrent meningiomas prior to reoperation or radiotherapy.

Purpose: To investigate the surgical, perfusion, and molecular characteristics of glioblastomas which influence long-term survival after treatment, and to explore the association between MR perfusion parameters and the presence of MGMT methylation and 1p/19q deletions. Materials and Methods: This retrospective study was approved by our institutional review board. A total 43 patients were included, all with pathologic diagnosis of glioblastoma with known MGMT methylation and 1p/19q deletion statuses. We divided these patients into long-term (${\geq}60\;months$, n = 7) and short-term (< 60 months, n = 36) survivors, then compared surgical extent, molecular status, and rCBV parameters between the two groups using Fisher's exact test or Mann-Whitney test. The rCBV parameters were analyzed according to the presence of MGMT methylation and 1p/19q deletions. We investigated the relationship between the mean rCBV and overall survival using linear correlation. Multivariable linear regression was performed in order to find the variables related to overall survival. Results: Long-term survivors (100% [7 of 7]) demonstrated a greater percentage of gross total or near total resection than short-term survivors (54.5% [18 of 33]). A higher prevalence of 1p/19q deletions was also noted among the long-term survivors (42.9% [3 of 7]) than the short-term survivors (0.0% [0 of 36]). The rCBV parameters did not differ between the long-term and short-term survivors. The rCBV values were marginally lower in patients with MGMT methylation and 1p/19q deletions. Despite no correlation found between overall survival and rCBV in the whole group, the short-term survivor group showed negative correlation ($R^2=0.181$, P = 0.025). Multivariable linear regression revealed that surgical extent and 1p/19q deletions, but not rCBV values, were associated with prolonged overall survival. Conclusion: While preoperative rCBV and 1p/19q deletion status are related to each other, only surgical extent and the presence of 1p/19q deletion in GBM patients may predict long-term survival.

Although pathogenesis of human rheumatoid arthritis (RA) remains unclear, arthritogenic T cells and downstream signaling mediators have been shown to play critical roles. An increasing numbers of therapeutic options have been added for the effective control of RA. Nevertheless, there is still a category of patients that fails treatment and suffers from progressive disease. The recently developed immunosuppressant CP-690550, a small molecule JAK kinase inhibitor, has been implicated as an important candidate treatment modality for autoimmune arthritis. In this study, we evaluated the therapeutic effect of CP-690550 on established arthritis using an SKG arthritis model, a pathophysiologically relevant animal model for human RA. CP-690550 treatment revealed remarkable long-term suppressive effects on SKG arthritis when administered to the well-advanced disease (clinical score 3.5~4.0). The treatment effect lasted at least 3 more weeks after cessation of drug infusion, and suppression of disease was correlated with the reduced pro-inflammatory cytokines, including IL-17, IFN-${\gamma}$, and IL-6 and increased level of immunoregulatory IL-10.

Objectives: The purpose of this study is to understand the experience of traffic accident patients with serious injury treated with Traditional Korean Medicine (TKM). Methods: This study was conducted on the basis of grounded theory. We recruited 10 participants who had been hospitalized in Dongguk University Bundang Oriental Hospital after traffic accident. Raw data was collected by in-depth interview, and analyzed by using constant comparison. The coding(open-axial-selective) was performed in order to create paradigm and theoretical model, which can explain main theme of this study. Results: Core phenomenon of this study was 'Experiencing TKM treatment as an alternative' and core category was 'Searching for the answer to the management of traffic accident sequela through TKM treatment' Conclusions: For patients with serious injury, 'Experiencing TKM treatment as an alternative' has meaning as the following: First, The absence of accurate radiography and surgical management makes it hard for patients to choose Korean medicine hospital immediately after traffic accident. Second, Effectiveness of TKM treatment should be evaluated in the long term. Third, TKM treatment is superior to Western medicine treatment in managing long-term patients who suffered from serious injury involved in traffic accident. Finally, Cooperative service of the Western medicine and TKM will provide more satisfactory medical care for traffic accident patients.

Background: Olfactory dysfunction, including anosmia and hyposmia is difficult to treat. Although the mechanism is not well known, stellate ganglion block (SGB) is used to treat olfactory dysfunction. There are no prior studies on the long-term effects of SGB on olfactory dysfunction. The purpose of this study was to evaluate the continuity of therapeutic effects and patient satisfaction with SGB treatment. Methods: This was a follow-up study carried out via a telephonic survey. The olfactory function of the patient was evaluated using a visual analog scale (VAS). We checked VAS three times: VAS-I (pre-treatment VAS), VAS-A (post-treatment VAS), and VAS-C (VAS at follow up telephone survey). We divided the subjects into 2 groups according to their responsiveness to SGB: the responsive (R group) and the unresponsive groups (UR group). Patient satisfaction was evaluated using a Likert scale. Results: Out of the 40 subjects, 37 responded to the telephone survey. In the UR group, there was difference in the olfactory function. However, in the R group, there were significant VAS differences; VAS-I was $9.6{\pm}0.7$, VAS-A was $5.1{\pm}4.2$, and VAS-C was $2.7{\pm}$2.7 (P < 0.05). On the Likert scale, patient satisfaction was as follows: grade 1, 17 patients (45.9%); grade 2, 6 patients (16.2%); grade 3, 6 patients (16.2%); and grade 4, 8 patients (21.6%). Conclusions: SGB is a safe, long-lasting, and effective therapeutic modality for olfactory dysfunction treatment.
