Purpose : Bell's palsy is defined as an idiopathic facial nerve paralysis of sudden onset. In spite of intensive clinical and experimental investigation, there is still uncertainty in the incidence, etiology, and preferred mode of treatment in children. The objective of this study was to analyze clinical outcome and prognosis of children with Bell' palsy. Methods : We analyzed 61 cases of Bell's palsy diagnosed at the Department of Wonkwang University Hospital from January 1998 to July 2006. The inclusion criteria were any children with acute isolated unilateral lower motor neuron type of facial nerve palsy. The clinical findings and investigations were reviewed including age, sex, affected site, seasonal incidence and result of steroid treatment. Chi-square and Fisher's exact test was used to compare clinical outcome between duration of complete recovery and age. Results : There was no difference in incidence according to sex or age. Incidence was higher in summer and winter. There was no difference in complete recovery rate and duration between steroid treated group and control group. In the group of children younger than 6 years, duration of complete recovery was shorter than older children. Conclusion : We found increasing the incidence of Bell's palsy in summer and winter. Children younger than 6 years had shorter duration in complete recovery.

Purpose: Supraventricular arrhythmia is a well-known complication of cardiothoracic surgery, and is common in patients wirth underlying cardiovascular disease. Also, it's treatment and prognosis are well known. However the incidence, the contributing factors, and the prognosis for supraventricular arrhythmias in noncardiothoracic surgical patients are less well known. This study was undertaken to investigate the incidence, the clinical presentation, the prognosis, and the factors comtributing to the prognosis for supraventricular arrhythmia in the surgical intensive care unit. Methods: We performed a retrospective study of 34 patients with newly developed or aggravated supraventricular arrhythmias in the surgical intensive care unit between March 2004 and February 2005. The incidence, the risk factors, and the prognosis of supraventricular arrhythmias were analyzed. Results: During a 12month period, the incidence of supraventricular arrhythmia was 1.79% (34/1896). Most patients had pre-existing cardiovascular disease and sepsis. The mortality rate was 29.4%, and the most common cause of death was multiple organ failure due to septic shock. The mean value of the APACHE II score was 20.9, and the surgical intensive care unit and the hospital lengths of stay were 9.9 days and 25.8 days, respectively. The APACHE II score measured when the arrhythmia developed was a significant factor in predicting mortality, Conclusion: Supraventricular arrhythmias result in increased mortality and increased length of stay in both the surgical intensive care unit and the hospital. The arrhythmia itself did not cause death, but a high APACHE II score incicated a poor prognosis. This may reflect the severity of the illness rather than an independent contributor to mortality.

Background: Bell's palsy (BP) is the most common cause of unilateral lower motor facial palsy. Recurrent paralysis of the facial nerve is unusual and reported in only 7-8%. Methods: A total of 394 consecutive patients with acute BP patients were enrolled at Daegu Catholic University Hospital from July 2005 to September 2012. We classified the patients into two groups-single BP and recurrent BP-and compared them by patient characteristics, clinical features, MRI findings, electrophysiologic findings and prognosis. The degree of BP was graded according to the House and Brackmann facial nerve grading system. Results: Recurrent BP was observed in 31 (7.9%) patients. The number of recurrence was varied from 2 to 5. The recurrent BP (9.7%) had more incidence of family history and MRI enhancement than those of single BP (2.2%, p=0.047). The single BP (63.4%) had better recovery than recurrent BP (45.2%, p=0.045). Conclusions: The recurrent BP had more incidence of family history, MRI enhancement and poor prognosis than the single BP.

Objective : The incidence of primary CNS lymphoma(PCNSL) has been increasing recently. The purpose of this study is to establish of prognostic factors and treatment options for PCNSL. Methods : Thirty-one PCNSL patients were treated in our institute between 1985 and 1997. All patients were histologically confirmed via stereotactic biopsy or open biopsy. The authors retrospectively analyzed clinical characteristics of PCNSL and prognostic factors, including histological cell types, immunohistological cell types and treatment options of PCNSL. Our data were statistically analyzed using Kaplan Meier survival curve and multivariated ANOVA test. Results : The clinical and radiological characteristics of PCNSL were resembled to those of other reports. The most common histological subtype was diffuse large cell type(55.5%). In immunohistolgical study, the incidence of T-cell lymphoma(35.7%) was very higher than that of others. The radiotherapy could prolonged patients' survival(p=0.021). One-year and 3-year survival rate of PCNSL were 66.9% and 45.9%, respectively. One-year survival rate of B cell and T cell lymphoma were 72.7% and 50.0%, respectively. The patients with B-cell lymphoma showed better prognosis than patients with T-cell lymphoma(p=0.049). Conclusion : On the basis of our data, active radiotherapy could prolong patients' survival. the T-cell lymphoma revealed higher incidence than those of other reports and had poor prognosis than that of B cell lymphoma.

Nocardiosis is an uncommon opportunistic bacterial infection which becomes a significant health problem due to its increasing incidence and high mortality rate. However, many nocardiosis patients are underdiagnosed by physicians. To summarize the clinical characteristics and management of nocardiosis would help with better diagnosis and prognosis of nocardiosis. This retrospective study was conducted based on the medical records of nocardiosis patients between January 2015 and December 2021 in a tertiary hospital in China. Overall, 44 nocardiosis patients with 54 specimens were included. The patients consisted of 26 males and 18 females with a mean age of 50.4 ± 13.2 years. Among 44 patients, 26 (59.1%) were previously given immunosuppressive therapy. Connective tissue diseases (CTDs) were the most common underlying disease (16/44). The most frequent infection sites were the lungs (17/44) and skin or soft tissues (8/44). Common symptoms included cough (23/44), expectoration (18/44), fever (15/44), and subcutaneous abscesses (15/44). Forty-five out of 54 specimens (83.3%) required over 48 hours of culture time for nocardiosis detection. Thirty-six patients were cured or improved, 5 patients were discharged from the hospital due to poor prognosis, and 1 patient died. The average diagnosis time of poor prognosis cases was 19.7 days, which was significantly longer than those of improved or cured patients (7.3 days). Immunosuppressed patients comprise a large part of nocardiosis cases, which is worth attention in clinical practice. Early diagnosis, specifically through prolonged cultivation time of specimen, could help achieve better prognosis of nocardiosis patients.

Purpose: This study aimed to evaluate the clinical features of children who have survived a water submersion incident, and to identify risk factors for prognosis. Methods: We retrospectively reviewed the medical records of patients who experienced submersion between January 2005 and December 2014. The patients were classified into 2 groups, according to complications, and prognostic factors were evaluated. Results: During the study period, 29 children experienced submersion (20 boys and 9 girls; mean age, $83.8{\pm}46.4$ months). Submersion occurred most commonly in the summer, with the peak incidence in August. The most frequent Szpilman clinical score was grade 5 (13 patients; 44.8%), followed by grade 6 (7 patients; 24.1%), and grades 1 or 2 (3 patients; 10.3%). Five children (17.2%) in the poor prognosis group died or had hypoxic ischemic encephalopathy, and the overall mortality rate was 6.9%. Poor prognosis after submersion was associated with lower consciousness levels (P=0.003), higher Szpilman scores (P=0.007), greater need for intubation and mechanical ventilator support (P=0.001), and longer duration of oxygen therapy (P=0.015). Poor prognosis was also associated with lower bicarbonate levels (P=0.038), as well as higher sodium, aspartate transaminase (AST), and alanine transaminase (ALT) levels (P=0.034, P=0.006, and P=0.005, respectively). Szpilman clinical scores were positively correlated with consciousness levels (r=0.489, P=0.002) and serum liver enzyme levels (AST and ALT; r=0.521, P=0.004). Conclusion: We characterized the prognostic factors associated with submersion outcomes, using the Szpilman clinical score, which is comparable to consciousness level for predicting mortality.

Purpose: Recently, the incidence of malignant melanoma has been steadily increasing. Malignant melanoma is already known to have poorer prognosis than other primary skin cancers. Despite the poor prognosis, it is relatively less known to the public so that a number of patients visit hospital carrying advanced stage tumor. Yet, extensive study about malignant melanoma is currently insufficient, and specific guidelines and statistical figures in Korea are almost inexistent. Therefore, authors reviewed patients with malignant melanoma who have visited our hospital for last 14 years. Methods: Between January 1994 and January 2008, 62 patients were diagnosed with malignant melanoma at our hospital. A retrospective study was performed with data from patients' charts and biopsy results. Annual incidence, mean age of onset, gender, tumor location, tumor thickness, pathologic ulceration, clinicopathologic subtype, and clinical AJCC stage were evaluated. Analysis of factors associated with survival were performed using the Cox proportional hazard model. Kaplan - Meier method was used to generate survival curves. Results: Clinicopathologic features of 62 patients (32 male, 30 female) with average age of 57 years were evaluated. Most lesions were found in lower limb, and the most common subtype was acral lentiginous melanoma. We could also find that age, tumor thickness, and clinical stage were the only significant prognostic factors. Conclusion: Clinicopathologic features of malignant melanoma were analyzed in this study, but the result is not ready to be generalized because the number of cases is too small. Further study must be performed to report clinical guidelines for prognosis and treatment for malignant melanoma patients in Korea.

Objective : The authors analyzed the incidence, the cause and the prognosis of hydrocephalus following aneurysmal subarachnoid hemorrhage to evaluate the risk factors of hydrocephalus and to provide the proper treatment method for hydrocephalus following aneurysmal subarachnoid hemorrhage. Methods : The 505 cases of subarachnoid hemorrhage followed by aneurysmal surgery from January 1990 to May 1999, were divided into shunt group and shunt-free group and we were reviewed for the clinical status, Fisher's grade, brain CT findings and prognosis. Results : The incidence of acute hydrocephalus was 37.2% of patients and 18.9% to developed chronic hydrocephalus. Shunt surgery due to chronic hydrocephalus was required in 6.5% of patients. We found following variables were significantly related to shunt-dependent hydrocephalus : high Hunt-Hess and Fisher grade, initial CT findings of intraventricular hemorrahge, posterior circulation aneurysm, preoperative rebleeding, delayed ischemic deficits, and initial high ventricular size index. There were no statistically significant relationships between shunt-dependent hydrocephalus and patient age or sex, timing of operation. The previous hypertension was not related to shunt dependent hydrocephalus. Prognosis in shunt group showed poor result. Conclusion : The risk factors of hydrocephalus following aneurysmal subarachnoid hemorrhage are high Hunt-Hess grade, high Fisher's grade, aneurysms of posterior circulations, preoperative aneurysmal rebleeding, delayed ischemic deficits, initial CT findings of intraventricular hemorrahge and initially increased ventricular size. The patients with these factors should the carefully observed and managed accordingly due to poor prognosis related to hydrocephalus requiring shunt operation.

The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass screening program. Cervical cancer prognosis is good due to an effective treatment such as surgery or radiation therapy, concurrent chemotherapy in the early stage. However, it is still a poor prognosis when advanced stage or recurrent. Some studies said that combined oriental and western medicine can improve the survival, quality of life, immune function, and decrease side effects in cervical cancer. In the western medical part, clinical practice guideline was published in 2006, 2007 and 2010 in Korea. In China, oriental medicine clinical practice guideline have been published in 2014. But there is no Korean medicine clinical practice guideline. This study will introduce the methods of diagnosis and the medical therapeutics which is commonly utilized for cervical cancer in Korea, and existing Korean medicine clinical practice guideline for Disease Analysis and Treatment (辨證論治). This study will be a meaningful study to establish clinical practice guidelines of Korean Medicine for cervical cancer.

Purpose: We aimed to study the relationship between thrombocytosis and clinical features of gastric cancerfocussing on platelet counts and gastric cancer progression through different TNM stages. Methods: According to the normal range of platelet count in our institution, 1,596 patients were divided to two groups: a thrombocytosis group (120 patients, > $400{\times}1000/{\mu}L$) and a control group (1,476 patients, ${\leq}400{\times}1000/{\mu}L$). Results: The incidence of thrombocytosis was 7.5%. Higher platelet counts were observed in patients with older age, larger tumor size, deeper invasion, lymph node metastasis, distant metastasis and advanced TNM stage. In multivariate logistic regression, tumor size, depth of tumor invasion, lymph node metastasis and TNM stage were independent risk factors for thrombocytosis of gastric cancer patients. On prognostic analysis, age, tumor size, tumor location, histologic type, depth of tumor invasion, lymph node metastasis, distant metastasis and TNM stage and platelet count were important factors. Tumor size, invasion depth, lymph node metastasis, TNM stage and the platelet count were independent prognostic factors. Conclusion: Thrombocytosis is associated with clinical features of gastric cancer patients and correlates with a poor prognosis.
