Posterior canal benign paroxysmal positional vertigo (PCBPPV) is the most common disease among patients who visited the st. Carollo hospital dizziness center with the head suddenly feeling rolling or rotational dizziness caused by head and body movements. Most patients showed improvements in symptoms after a single treatment. On the other hand, there are more causes requiring multiple treatments. This study examined the factors affecting the canalithiasis repositioning maneuver for symptom recovery of dizziness, which is posterior BPPV. Dizziness patients who visited the dizziness center of PCBPPV were classified. From March 2008 to November 2010, the cure rate of 165 posterior BPPVs patients was investigated. The success rate after the first, second, third, and further treatments was 57.6%, 17.6%, 10.3%, and 14.5%, respectively. The factors affecting treatment of PCBPPVs included traumatic, medical disease, cerebral infarction, small vessel disease, vestbro basilar artery insufficiency (VBI), cerebrovascular disease, brain disease, and vestibuloplasty (P<0.05). Vomiting, nausea, and syncope can be treated easily by considering the factors affecting these treatments. If the related diseases are combined with the treatment of the canalithiasis repositioning maneuver for symptom recovery of dizziness, the results will show an improvement in daily life that is free from painful dizziness.

Purpose: To evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) for postoperative pain after surgery around ankle. Materials and Methods: We included 21 patients who performed an operation around ankle from 2009 to 2013. 4 times ESWT were applied to the patients who have tenderness more than visual analog scale (VAS) point 4. We evaluated the VAS at each sessions and final follow-up, and American Orthopedic Foot and Ankle Society ankle-hindfoot score (AFOAS) was checked at preoperative and final follow-up. Patient's satisfaction and complications were surveyed. Results: Preoperative VAS was mean 4.7, postoperative pain VAS was mean 6.0 at 4.5 months follow-up. The VAS after ESWT each session at 1, 2, 3 weeks and final follow-up were 4.8, 3.2, 2.3, 2.9, respectively. Mean final follow-up period was 9.4 months. Final VAS were significantly decreased (p<0.001). Final VAS were increased from VAS at last session of ESWT, however, not significant (p=0.189). AOFAS significantly improved from preoperative 60 to final follow-up 86 (p<0.001). Excellent was 12 patients (57%), good was 4 patients (19%), no change was 3 patients (14%) and poor was 2 patients (9%). 1 patient complained a dizziness and nausea during ESWT. Conclusion: ESWT for postoperative pain after ankle surgery shows satisfactory pain reduction in 76% of all patients without severe complication.

Imidapril(Tanatril$^{(R)}$), a newly developed ACE inhibitor, has been used to treat hypertension and congestive heart failure. This study was designed to assess the antihypertensive effect and safety of Imidapril(Tanatril$^{(R)}$) in patients with essential hypertension. 5-10mg of imidapril(Tanatril$^{(R)}$) was administered once a day in 30 patients with essential hypertension and followed up for 8 weeks. We tested the drug's effectiveness, safety, and the incidence of imidapril induced dry coughs. After 8 weeks of treatment with imidapril, 76.2%(16/21) of patients showed lowered blood pressure and 47.6% showed normal blood pressure. The overall incidence of adverse effects was 33.3%(7/21), and among these adverse effects, dry cough was shown in only 9.5%. Thus, we concluded that imidapril(Tanatril$^{(R)}$) is as safe and effective as other ACE inhibitors, especially with imidapril showing very little incidence of dry cough compared to other ACE inhibitors.

This study was conducted to evaluate the effect of the antenatal ambroxol administration to mothers who were in danger of imminent preterm delivery in preventing the neonatal respiratory distress syndrome(RDS). Forty-two preterm newborn infants who were delivered at Yeungnam University Hospital from January 1996 to December 1997 were divided into two groups, 21 in ambroxol-treated group and 21 in control group. Six cases of the respiratory distress syndrome were developed from 21 ambroxol-treated infants, but 13 cases of RDS, from 21 control infants. This result indicated a significant reduction of the occurrence of RDS by antenatal administration o[ ambroxol (p<0.05). There were no differences in the occurrence of adverse effects of ambroxol in mothers between the two groups. There was also no difference between pre- and post-treatment hematologic and biochemical parameters in ambroxol-treated group. In conclusion, when premature delivery is expected, the administration of ambroxol before delivery enhances lung maturation in premature newborn infants and prevents the occurrence of respiratory distress syndrome without significant adverse effects.

Purpose : To assess the feasibility and the toxicity of the neoadjuvant chemotherapy on the treatment of patients with locoregionally advanced nasopharyngeal carcinoma. Methods and Materials : We analyzed 77 previously untreated and histologically confirmed advanced stage nasopharyngeal carcinoma patients treated with neoadjuvant chemotherapy followed by radiation therapy at the Seoul National University Hospital between 1984 and 1996. The stage distribution was as follows : AJCC stage III-2, stage IV-75. Sixty-six patients received infusion of 5-FU (1000 mg/m$^2$, on Day 1$\~$5) and cisplatin (100 mg/m$^2$, on Day 1), eleven patients received infusion of 5-FU (1000 mg/m$^2$, on Day 1 $\~$5) and carboplatin (300 mg/m$^2$, on Day 1) as neoadjuvant chemotherapy Prior to radiation therapy. The median follow-up for surviving patients was 44 months. Results : The overall chemotherapy response rates were 87$\%$. The toxicities of chemotherapy were mild. Only 3 patients experienced Grade 3 toxicities (1 for cytopenia, 2 for nause/vomiting). The degree of radiation induced mucositis was not severe, and ten patients developed Grade 2 mucositis. The 5-year overall survival rates were 68$\%$ and the 5-year disease free survival rates were 65$\%$. The 5-year freedom from distant metastasis rates were 82$\%$ and 5-year locoregional control rates were 75$\%$. Conclusion : This single institution experience suggests that neoadjuvant chemotherapy improves overall survival and disease free survival for patients with advanced stage nasopharyngeal carcinoma without increase of toxicity.

Purpose: The aim of this study was to compare quality of life of long-term survivors after a subtotal or a total gastrectomy for gastric cancer. Materials and Methods: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire and QLQ-STO22 questionnaire were used to assess quality of life of 166 patients on their 5th annual follow-ups after gastrectomy for gastric cancer. One hundred twenty-six patients underwent a subtotal gastrectomy and 40 patients a total gastrectomy. Results: The subtotal gastrectomy group revealed a trend to have better quality of life in functional scales (physical, role, emotional, cognitive and social), fatigue, pain, dyspnea, diarrhea and financial difficulties. The total gastrectomy group showed a trend to have better quality of life in the global health status and quality of life, nausea and vomiting, insomnia, appetite loss and constipation. In all scales of the EORTC QLQ-STO22, the subtotal gastrectomy group had a trend to have better quality of life. However these did not reach the statistical significance. Conclusion: Surgeons may not limit the extent of resection concerning long-lasting poor quality of life. Oncologically sound resection is recommended.

This is a report of gastric metastases secondary from a primary small cell carcinoma of the lung in two men. Blood-borne metastatic involvement of the stomach by cancer is a rare entity. According to the reports in the literature the prevalence of metastasis to the stomach occurs in 0.4% and the most common cell type of the primary lung carcinoma is large cell type(3.7%) followed by adenocarcinoma(2.4%), small cell carcinoma(1.7%) and squamous cell carcinoma(0.7%). The most common tumors that spread to the stomach through the blood stream are malignant melanoma, breast carcinoma and lung carcinoma. Most of the gastrointestinal tract metastases had no specific symptoms because of its submucosal involvement. The prognosis was poor and the mean survival period from the onset of symptoms was 49 days. The first patient was a 56-year-old man who had primary lung carcinoma with brain metastasis. Gastroscopic findings showed two elevated mass lesions in the anterior wall of the mid body with central ulcer and the posterior wall of the fundus with intact surface mucosa. Pathologic examination of stomach tissue revealed small cell type tumor cells infiltrate in the stomach wall segmentally without destruction of the glands. The second patient was a 67-year-old man who had no other evidence of the distant metastasis. Gastroscopic findings showed a huge, oval shaped, ulcerofungating mass with deep penetrating central ulcer coated with dirty exudate in the anterior wall from mid to upper body of the stomach, and thickened elevated rugal folds in the posterior wall of the fundus. Pathologic examination of stomach tissues revealed the small cell type tumor cells showing small smudged nucleus infiltrate into the mucosa of the stomach and the architecture of mucosa intact. We report the two cases of metastatic gastric cancer from the primary small cell lung carcinoma with the literature review.

오디는 옛부터 보혈자음(補血滋陰), 생진윤조(生津閏操), 현훈이명(眩最耳鳴), 심계실면(心悸失眠), 수발조백(鬚髮早白) 등을 치료하는 효능을 가진다고 알려져 있다. 상심자(桑 子)라 하여 뽕나무 열매로서 한방에서 상심(桑 ), 상실(桑實), 오심(烏 ), 흑심(黑 ) 등으로 지칭되며, 뽕나무과(Moraceae)에 속하는 뽕나무(Morus alba L)의 성숙한 과실로 취화과(聚花果)에 속하며 작은 수과(瘦果)가 많이 모여 이루어진 장원형으로 길이 1 내지 2 cm, 지름 0.5 내지 0.8 cm이며 황갈색, 갈홍색 또는 암자색을 띠고 짧은 줄기가 있다. 작은 수과(瘦果)는 난원형으로 조금 납작한 편이며, 길이는 약 2 mm, 너비는 약 1 mm 이고 육질의 화편(花片) 4개가 둘러싸고 있다. 그러나 아직까지는 오디에 대하여 자연과학적인 연구방법을 이용하여 구체적으로 연구된 바가 많지 않다. 또한 이의 생리활성 성분에 대해서도 그 작용과 연관지어 보고된 바가 많지 않다. 뇌졸중 가운데 뇌조직으로 가는 혈액 공급의 감소 혹은 차단으로 발생되는 허혈성 뇌졸중(ischemic stroke)은 전체 뇌졸중 환자의 약 80%정도를 차지하고 있으나 아직까지 뇌신경세포 손상기전의 복잡성 등으로 뇌졸중으로 발생하는 뇌신경세포의 손상을 보호해 줄 수 있는 물질이 개발되어 있지 못한 실정이다. 한편, 천연물로부터 뇌허혈 보호작용을 가지는 물질의 도출은 주로 한방에서 처방을 중심으로 이루어지고 있으며, 따라서 처방으로부터 신경보호작용을 가지는 물질의 도출은 그 처방에 함유되어 있는 각종 생약이 갖는 다양한 활성으로 인해 어려운 점이 있으며, 비록 효과가 있다고 하더라도 과학적인 입증자료가 매우 미비한 실정이다. 이에 본 연구에서는 위에 언급된 자료를 토대로 오디추출물이 뇌허혈에 효과가 있을 것이라는 가정하에 in vitro system을 이용하여 오디추출물의 신경보호작용기전을 검색하고자 DPPH radical 의 생성억제효과, PC12 cell line을 이용한 산화적 스트레스에 의한 오디추출물의 방어효과, LSP에 의하여 활성화된 BV-2 cell에 미치는 영향 등을 검색하였다. 오디의 DPPH 소거활성은 단일화랍물인 bacicalein과 유사한 효과를 나타냈으며 PC12 cell line을 이용한 산화적 스트레스에 의한 오디의 방어 효과는 LDH activity를 행한 결과 농도 의존적으로 LDH 유리 량을 감소시켰다. 뇌손상시에 오디추출물의 염증방어 효과를 관찰하기 위하여 microglial cell line인 BV2 세포주를 선택하여 배양한 후 LPS로 자극을 준 후 일차적인 염증지표인 NO양을 측정한 결과 BV2 cell에 LPS 100 ng/ml을 처리하는 경우 nitrite량이 유의적으로 증가하였는데 이때 오디추출물을 1, 5, 10 ug/ml의 용량으로 처리하는 경우 역시 저농도에서 NO생성량을 감소시켰다. 정리해보면 뽕나무과 식물인 오디는 신경보호효과가 있는 것으로 사료되는데 이러한 효과는 아마도 오디의 항산화효과에 기인한 것으로 추정된다.

Purpose : We evaluated clinical presentations of brain abscesses, including predisposing factors, causative organisms, and mortality rate in neonates and children. Methods : We retrospectively reviewed the medical charts of neonates and children with brain abscesses treated at Severance Hospital from January 1997 through December 2006. Results : Among 27 neonates and children with brain abscesses, overall mortality was 22 % and 38% of survivors developed neurologic sequelae. The mortality rate was 38% in 8 infants with brain abscesses. The most common location of brain abscesses were frontal and parietal lobes, followed by temporal lobe. There were 7 cases with multiple brain abscesses. Streptococci (33%), Staphylococci (27%), and Gram-negative enterics (20%) were commonly isolated. The common predisposing conditions were neurosurgical procedure (30 %), cyanotic congenital heart disease (15%), and sinusitis/otitis (7%). Fever (74%), headache (37%), nausea/vomiting (33%), and altered mental status (33%) occurred commonly. Compared with children older than 1 year of age, infants were associated with multiple brain abscesses (63%, P=0.011) and high rates of death or neurologic sequelae (88%, P= 0.033). Conclusion : We should have a high index of suspicion in order to recognize the condition as early as possible, especially in infancy with brain abscesses who presents vague or nonspecific symptoms and signs.
