Recently, the detection of traumatic intracerebral hematoma has been greatly expedited by the advent of computed tomography. However, Traumatic Basal Ganglia Hematoma(TBGH) has remained rare and its prognosis has been regarded as poor. The authors obtained following results from the analysis of clinical features and outcome on 50 cases of TBGH who has been treated at the department of neurosurgery, Wonju Christian Hospital from January, 1984 to June, 1988. 1) The incidence of TBGH was 2% of all head-injured patients. 2) The average age of patient was 26.6 years, and the most common cause was motorvehicular accident(80%). 3) The clinical features revealed mental deterioration on 44 cases, followed by motor weakness(23 cases), and decerebrate rigidity(16 cases). 4) The frequent location of hematoma was putamen(27 cases, >50%), internal capsule(9 cases, 14%). 5) The combined lesion showed mostly lower GCS(Glasgow Coma Scale) than solitary lesion(P<0.001). 6) The groups of both GCS above 8(P<0.001) and small hematoma volume below < 15ml(P<0.001) showed relatively good outcome.

PURPOSE: Sentinel lymph node (SLN) biopsy has become a new standard procedure in the treatment of patients with early breast cancer. Furthermore, many institutions have begun offering the sentinel lymph node biopsy without simultaneous axillary dissection as a possible standard procedure when the SLN was free from tumors. For appropriate intraoperative decision making on the presence of cancer cells in axillary lymph nodes, a fast and accurate method to assess the SLN is required. The authors performed a prospective investigation of the relative merits of rapid cytokeratin immunohistochemical (IHC) staining of the SLN removed during the operations of breast cancer patients. METHODS: Between December 2002 and August 2003, 38 patients with T1and T2 breast cancer were enrolled after undergoing successful sentinel lymph node biopsy. A total of 60 sentinel lymph nodes (mean number, 1.58) were biopsied and first examined by hematoxylin-eosin (H&E) staining. All the tumor free sentinel lymph nodes by H&E stained section were immunostained for cytokeratin using a rapid immunohistochemical assay (Cytokeratin (PAN), 1:50, Newcastle, UK) during the operation. Finally, the sentinel lymph nodes were submitted for paraffin embedding and serial section after surgery. Both H&E stained and cytokeratin immunostained sections were also performed. RESULTS: This technique has a turnaround time of less than 20 minutes during the operation. Rapid IHC staining revealed 4 positive sentinel lymph nodes that were negative for metastasis by H&E staining. Among these false negative 4 cases, two cases had problems with the frozen section of H&E staining and the other 2 cases had problems due to micrometastasis. This study showed a sensitivity of 88.89%, a specificity of 100%, an accuracy of 98.33%, and a negative predictive value of 98.08%. The false-negative case (1 of 52), which was negative on H&E staining and rapid IHC staining during the operation, was disclosed as positive only after a serial permanent section examination with IHC stain. CONCLUSION: The introperative examination of sentinel lymph nodes is a highly accurate and effective way of predicting the axillary lymph node status of patients with breast cancers. This may be a promising technique in deciding whether to spare axillary lymph node dissection for the patient in the operating room.

BACKGROUND: The bone graft for the alveolar cleft has been accepted as one of the essential treatments for cleft lip patients. Precise preoperative measurement of the architecture and size of the bone defect in alveolar cleft has been considered helpful for increasing the success rate of bone grafting because those features may vary with the cleft type. Recently, some studies have reported on the usefulness of three-dimensional (3D) computed tomography (CT) assessment of alveolar bone defect; however, no study on the possible implication of the cleft type on the difference between the presumed and actual value has been conducted yet. We aimed to evaluate the clinical predictability of such measurement using 3D CT assessment according to the cleft type. METHODS: The study consisted of 47 pediatric patients. The subjects were divided according to the cleft type. CT was performed before the graft operation and assessed using image analysis software. The statistical significance of the difference between the preoperative estimation and intraoperative measurement was analyzed. RESULTS: The difference between the preoperative and intraoperative values were -0.1+/-0.3 cm3 (P=0.084). There was no significant intergroup difference, but the groups with a cleft palate showed a significant difference of -0.2+/-0.3 cm3 (P<0.05). CONCLUSIONS: Assessment of the alveolar cleft volume using 3D CT scan data and image analysis software can help in selecting the optimal graft procedure and extracting the correct volume of cancellous bone for grafting. Considering the cleft type, it would be helpful to extract an additional volume of 0.2 cm3 in the presence of a cleft palate.

The purpose of our study was to analyze the incidence of incidental thyroid cancers which were detected by simultaneous sonographic examination of breast and thyroid glands. Between January 2001 and March 2004, 518 patients were diagnosed with breast cancer after modified radical mastectomy (n=369) or breast conserving surgery (n=149). We screened thyroid glands when we examined breast for diagnosis and follow-up after surgery. If we found the sonographic finding of suspicious for malignancy in thyroid, we immediately performed ultrasound-guided fine needle aspiration biopsy (FNAB). Forty-two cases showed suspicious sonographic findings and of those, 18 cases (42.9%) were determined to have suspicious malignant cytology by ultrasound guided FNAB. Among 518 breast cancers, total 13 cases (2.5%) were diagnosed with papillary carcinoma after thyroidectomy. The mean longest diameter of the thyroid masses was 9.9mm (range 1-30mm). Six cases (6/13, 46.2%) were diagnosed as simultaneous breast and thyroid cancers, and the rest of the thyroid cancers were detected after 6 to 33 months (mean 16.5 months) after surgery. In conclusion, the patients with breast cancer had a high incidence (2.5%) of thyroid cancer. Sonographic screening is useful for the early detection of thyroid cancer.

Diversities of Korean species belonging to the genus Volvariella have been studied through forty five dried specimens collected throughout the Korean peninsula for 28 years, from 1972 to 2000, and preserved in NIAST's herbarium. We have found one unrecorded species of the genus Volvariella in Korea: V. villosavolva (Lloyd) Sing, Stirp Taylori Korean common names were designated. Ten species of the genus Volvariella including the recorded Korean species of Volvariella have been identified and the keys to the species were constructed.

BACKGROUND: Sleep is an essential restorative physiologic phenomenon. Impaired sleep results in significant negative effect to the health. Symptoms like sleep initiation difficulty, frequent awakening, severe snoring have related to poor sleep quality. We studied frequency and compared the characteristics of common sleep disorders at family practice. METHODS: We surveyed patients over 18 years of age and their guardians who visited 16 familial practices for 6 days. We investigated sleep characteristics, frequency of sleep disorder and associated factors by questionnaires and analyzed by frequency analysis, Spearman's correlation coefficient, multiple logistic regression. RESULTS: We enrolled 1,117 participants. Older participants were more likely to report early sleep onset and off time, short sleep duration. Mean number of awakening during a typical night is 1.69. Female complained difficulties in initiation and maintenance of sleep more than male. A total of 32.5% had these insomnia symptoms and related to hypertension, stroke, stress, arthralgia, depression, urological disorder. 31.1% had excessive daytime sleepiness, related to stress, arthralgia, depression. Loud snoring and gasp for breath showed positive correlation between male, high BMI. Disrupted sleep over 3 times was related to old age, female, diabetes, hypertension, stroke, stress, arthralgia, depression. Restless leg syndrome were high in elderly, high BMI, stress, arthralgia and depression. CONCLUSION: About one in three who visit in primary medical practice have sleep disorder symptoms like insomnia, daytime fatigue, snoring. 3% of them have gasp for breath, 8% have restless leg syndrome.

BACKGROUND: Though leptin, the adipocytes-derived hormone, plays an important role in obesity, it can act as a growth factor for several cancers including gastrointestinal malignancies. Based on this background, we investigated whether leptin expression correlated with the clinicopathological characteristics or disease outcome in patients with colon cancer. We immunohistochemically analyzed the expression of leptin in a "colon adenoma-carcinoma sequence" in the normal colon mucosa, an adenomatous polyp and adenocarcinoma tissue, from a surgical resection for each patient. METHODS: We collected samples from 24 patients with a colorectal adenocarcinoma that was removed in either a total colectomy or hemicolectomy, and who presented with an adenomoatous polyp and an adenocarcinoma in the same surgical specimen. Leptin expression was assessed using immunohistochemical methods and was evaluated by grading the staining intensity as 0, +1, +2, +3. RESULTS: Whereas leptin expression was observed in 4.2% (1/24) of the normal colon mucosa, adenomatous polyps and adenocarcinomas showed 33.3% (8/24) and 50.0% (12/24) expression of leptin, respectively (p<0.05), suggesting that leptin expression in the adenomatous polyps and adenocarcinomas was higher than in the normal colon mucosa (p<0.05). There was no significant difference in leptin expression between the adenomatous polyps and adenocarcinomas, statistically. There was no relationship between leptin expression and patients age, sex, BMI (body mass index), cancer stage, and lymph node metastasis. However, the tumor size in the positive leptin expression group was larger than in the negative leptin expression group (5.6+/-2.2 cm vs 3.9+/-1.4 cm; p<0.05) CONCLUSIONS: Since leptin expression in adenomatous polyps and adenocarcinomas was higher than in the normal colon mucosa and leptin expression significantly correlated with the tumor size, leptin might play a role in the development of an adenomatous polyp and an adenocarcinoma in the colon. However, leptin does not contribute to the progression of colon adenoma, and further evaluation studies will be required.

Dieulafoy's lesion is an exposed submucosal artery associated with a minute mucosal defect in the stomach, and it is a rare cause of profuse, but intermittent gastrointestinal bleeding. Less commonly, similar lesions have been identified in the duodenum, jejunum, colon, and in rare cases, the rectum. Only four cases of rectal Dieulafoy's lesion have been reported in English Medical literature: one case involved a child, two in otherwise healthy young men, and one in on elderly man. In this report, two elderly men are described, who suffered an massive hematochezia from a small rectal mucosal defect with a visible vessel. Control of the bleeding was successfully achieved with on endoscopic sclerotherapy or hemoclipping. The fact that rectal Dieulafoy disease is one of the causes of massive hematochezia should serve as a reminder in future cases, especially involving alcoholics and elderly men.

PURPOSE: This randomized phase III study was designed to compare the efficacy and safety of irinotecan plus cisplatin (IP) over etoposide plus cisplatin (EP) in Korean patients with extensive-disease small-cell lung cancer (SCLC). MATERIALS AND METHODS: Patients were randomly assigned to receive IP, composed of irinotecan 65 mg/m2 intravenously on days 1 and 8+cisplatin 70 mg/m2 intravenously on day 1 every 3 weeks, or EP, composed of etoposide 100 mg/m2 intravenously on days 1, 2, 3+cisplatin 70 mg/m2 intravenously on day 1, every 3 weeks for a maximum of six cycles, until disease progression, or until unacceptable toxicity occurred. The primary endpoint was overall survival. RESULTS: A total of 362 patients were randomized to IP (n=173) and EP (n=189) arms. There were no significant differences between IP and EP arms for the median overall survival (10.9 months vs. 10.3 months, p=0.120) and the median progression-free survival (6.5 months vs. 5.8 months, p=0.115). However, there was a significant difference in response rate (62.4% vs. 48.2%, p=0.006). The pre-planned subgroup analyses showed that IP was associated with longer overall survival in male (11.3 months vs. 10.1 months, p=0.036), < 65 years old (12.7 months vs. 11.3 months, p=0.024), and Eastern Cooperative Oncology Group performance status 0/1 (12.4 months vs. 10.9 months, p=0.040) patient groups. The severity of treatment-related adverse events such as grade 3/4 anemia, nausea and diarrhea was more frequent in patients treated with IP. CONCLUSION: The IP chemotherapy did not significantly improve the survival compared with EP chemotherapy in Korean patients with extensive-disease SCLC.
