OBJECTIVE: The purpose of this study was to review the safety and durability of aneurysms treated with stent-assisted coiling of ruptured anterior communicating artery aneurysms with small parent vessels (< 2.0 mm). METHODS: Retrospective review of all ruptured aneurysm treated with stent assisted endovascular coiling between March 2005 and March 2009 at our institution was conducted. We report 11 cases of the Neuroform stent placement into cerebral vessels measuring less than 2.0 mm in diameter (range, 1.3-1.9 mm) in anterior cerebral artery. Clinical follow-up ranged from 3 to 12 months and imaging follow-up was performed with cerebral angiography at 6 months and 12 months after discharge. RESULTS: Complete occlusion was achieved in 10 patients, and a remnant neck was evident in one. No stent displacement or no dislodgement occurred during stent placement. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. We performed follow-up angiography in all patients at 6 months and/or 12 months from the first procedure. The follow-up angiographic data showed successfully results except one in-stent stenosis case. All patients improved clinical performances except one patient with severe vasospasm who showed poor clinical condition initially. CONCLUSION: We have safely and successfully treated 11 vessels smaller than 2.0 mm in diameter with self-expanding stents with good short and intermediate term results. More clinical data with longer follow-ups are needed to establish the role of stent-assisted coiling in ruptured aneurysms with small parent vessels.

Authors presented the serial changes of brain MRI findings in two cases of cryptococcal meningitis. The MRI findings of the first patient (53-year-old female) consisted of dilated Virchow-Robin spaces, leptomeningeal enhancement, cryptococcomas and hydrocephalus. Dilated Virchow-Robin spaces were noted on the first MR obtained 33 days after symptom onset. The size and number of dilated Virchow-Robin space gradually decreased since 119 days after symptom onset (62 days after treatment). Faint leptomeningeal enhancement was found at cerebellar region on the first MRI, which became more distinct and intense on the day 119, probably due to improper treatment. The leptomeningeal enhancement decreased on the day 156. Mild hydrocephalus was noted on MRI obtained 70 days after symptom onset, which markedly aggravated on the day 119. It decreased after steroid therapy alone. Enhancing crytococcomas of variable size were noted at the right temporal lobe and cerebellum on MRI of the day 119, which decreased in size and number on the day 156. On the day 295 MRI showed nearly disppearance of the dilated Virchow-Robin space, but faint leptomeningeal enhancement, cerebellar crytococcomas and hydrocephalus still remained. The MRI findings of the second patient (36-year-old female) showed the findings similar to those of the first patient. Initial MRI obtained 18 days after symptom onset showed no abnormal findings. Dilated Virchow-robin spaces were noted on the day 36 (13 days after treatment onset), which nearly disappeared on the day 109. Enhancing cryptococcomas in both basal ganglia and cerebral cortex and leptomeningeal enhancement were noted on MRI of the day 136. Both cryptococcomas and leptomeningeal enhancement decreased in size and enhancing degree on the day 157. Hydrocephalus was noted on the day 109.

Percutaneous biliary drainage is an effective new nonsurgical method for combined external/internal catheterdecompression of obstructed extrahepatic bile ducts. Molnar and Stockum, and more recently others, have reportedsucdess utilizing this approach to establish biliary drainage in patients with obstructive jaundice. Percutaneousbiliary drainage was performed in 9 patients with obstructive jaundice. Internal drainage was accomplished in 4patients (44.4%), and external drainage in 5 patients (55.6%). Major complications occurred in 2 patients; bileleakage, one; sepsis, one. Minor complications occurred in 7 patients; mild or high fever, 5 cases; transienthemobilia, 2 cases. The catheter management problems encoutered including pain, catheter dislodgement ormigration, lumen occulusion, and external bile leakage.

OBJECTIVE: We analyzed the main causes leading to a poor outcome (severe disability, a vegetative state and death) following surgical treatment for ruptured intracerbral aneurysms. METHODS: Between January 1994 and December 2007, we maintained a retrospective database of 339 patients who underwent surgical clipping. The various causes we investigated were the technical problems during operation, the initial SAH or ICH, vasospasm, hydrocephalus and the post-operative medical complications. The clinical outcome was assessed according to the Glasgow Coma Scale (GOS). RESULTS: There were 263 cases of good outcomes (77.6%) and 76 cases of poor outcomes (22.4%). The three main causes of a poor outcome were 1) preoperative causes such as the direct insult of the initial SAH and ICH in 21 cases (27.6%), 2) intra-operative causes such as the technical problems during dissection and clipping of the aneurysm neck in 29 cases (38.2%) and 3) postoperative causes such as clinical vasospasm in 16 cases (21.1%). The mean follow-up period was 17.6 months (range : 2 months to 9 years). CONCLUSION: A meticulous neck dissection and complete obliteration of the aneurysm preserving parent arteries and perforators are the most effective and prime methods that surgeons can employ to reduce the rate of poor outcomes when performing ruptured aneurysm surgery.

A quantitative assessment of the testicular biopsy, and serum hormone levels( testosterone, prolactin, and follicle-stimulating and luteinizing hormones) were studied in 10 spinal cord injured men and comparison of these parameters to normal controls were performed. The mean number of Sertoli cells, mature spermatids, tubular diameter and tubular wall thickness were determined in both groups and analyzed. In the spinal cord injury group the mean number of mature spermatids per tubule was significantly lower and the mean number of Sertoli cells per tubule was significantly higher than in controls(p<0.05). Serum testosterone and luteinizing hormone values were significantly higher in the spinal cord injury group than in controls(p<0.05). These significant differences of the quantitative parameters of the testicular biopsy and hormonal values that may contribute to the reproductive dysfunction.

OBJECTIVE: This study was investigated on the relationship the degrees of proteinuria with the maternal characteristics, maternal and the neonatal outcomes. The correlation between the result of single urine protein- to-creatinine ratio and the amount of 24 hour urine protein was also investigated. METHODS: From December 1999 to June 2002, 63 patients were enrolled in this study. They were divided into two groups by the degree of proteinuria at 24 hour urine, single urine and dip stick test, respectively. Each two groups was compared with the maternal characteristics, gestational age, the maternal and the neonatal outcomes. The correlation between single urine protein-to-creatinine ratio and the amount of 24 hour urine protein was analyzed statistically. RESULTS: Each two groups of single urine and dip stick test had no differences in maternal characteristics, gestational age, maternal and the neonatal outcomes. However, in two of 24 hour urine, massive proteinuria group had poor maternal and neonatal outcomes compared with control group (p value 0.01). Single urine protein-to-creatine ratio and the amount 24 hour urine protein had borderline correlation (p value 0.064). CONCLUSION: The presence of proteinuria influences on maternal and neonatal outcomes. Moreover, the massive proteinuria group had more maternal and neonatal complication than control group. The result of single urine protein-to-creatine ratio had borderline correlation with the amount of protein in 24 hour urine collection.

Background: Prevention of chronic diseases such as hypertension and diabetes is important, but few studies have identified barriers to healthy lifestyle practices among adults in their 30-50s. Therefore, this study is intended to be used as basic data for establishing a prevention and control strategy for chronic diseases. Methods: This study is a qualitative content analysis study using the focus group interview methodology. According to the inductive content analysis method, data were analyzed through the steps of ‘making sense of the data and whole’, ‘open coding’, ‘grouping’, ‘categorization’, and ‘abstraction’. Results: The categories of barriers to healthy lifestyle practice were derived as follows. ‘Low interest in health care’ in the intrapersonal domain, ‘absence of an assistant’ in the interpersonal domain, ‘organizational environment in which it is difficult to a healthy lifestyle practice’ in the organizational domain, ‘lack of infrastructure’ and ‘restrictions on use of public health centers’ in the community domain. Conclusions For the prevention and management of chronic diseases, adults in their 30-50s should be encouraged to take an interest in healthy lifestyle practices and increase their will. For healthy lifestyle practice, it is necessary to allow family members and friends to participate as helpers. In addition, at work, employers should pay attention to workers' health management, adjust working hours, and reduce the burden of company dinner to create an organizational environment for healthy lifestyle practice. Lastly, infrastructure such as public sports facilities should be additionally expanded, and the contents of public health centers' programs should be promoted.

OBJECTIVE: This study was designed to examine swallowing function of 16 head and neck surgical patients who had postoperative swallowing difficulties and to identify the relationship between the physiologic causes of aspiration and the surgical procedure in each patient. METHOD: Group A was five patients who had partial pharyngolaryngectomy due to hypopharyngeal cancer, Group B was nine patients who had wide excision due to oral cavity cancer, and Group C was two patients who had supraglottic horizontal laryngectomy due to supraglottic laryngeal cancer. Their swallowing function was evaluated with videofluoroscopic swallowing study (VFSS). RESULTS: Aspiration occurred in 40% of patients with partial pharyngolaryngectomy, 44% of patients with wide excision, and 100% of patients with supraglottic horizontal laryngectomy. Group A showed swallowing difficulty because of reduced laryngeal closure and reduced pharyngeal peristalsis. Group B showed swallowing difficulty because of reduced pharyngeal peristalsis, reduced laryngeal function, and impaired tongue control. Group C showed swallowing difficulty for impaired tongue control, reduced laryngeal function, reduced pharyngeal peristalsis, and late swallowing reflex. Most of the patients who had had head and neck cancer surgery can regain normal swallowing function after adequate swallowing rehabilitation. CONCLUSION: Each group of head and neck surgical patients had different cause of swallowing difficulty. The knowledge of the determinant component of swallowing pathophysiology is important for successful swallowing rehabilitation.

Purpose: Laparoscopic colorectal surgery is technically demanding and needs a longer learning curve than open surgery. HALS (hand-assisted laparoscopic surgery) is a useful alternative to conventional laparoscopic surgery (CLS) because of its palpability and hand dissection. We compared the learning curves between HALS and CLS for colorectal surgery. Methods: A prospective study without randomization was conducted with the participation of two colorectal surgeons who had not experienced a laparoscopic colorectal operation. The collected data included operative features, oncologic outcomes, and early clinical outcomes. Fifty patients were enrolled in each group, the HALS group and the CLS group. Results: None of the operations converted to open surgery. The operative time was significantly shorter in the HALS group than in the CLS group (149.6+/-34.6 minutes versus 179.1+/-36.5 minutes, P<0.001). On a subgroup analysis of the operative time in the anterior resection, the operative time was consistent after the 13th operation in HALS group. However, in CLS group, there was a continuous fluctuation of the operative time until 25 cases. In regard to the oncologic outcome, the numbers of total harvested lymph nodes and the proximal and the distal margins in the anterior resection showed no statistical differences (P=0.400, P=0.908, and P=0.073, respectively). The early clinical results were similar in both groups. Conclusions: In the learning curve study, the HALS group had a shorter operative time and reached a learning curve plateau earlier than the CLS group. Other parameters, such as the oncologic results and the early postoperative clinical outcomes, showed no differences between the two groups.
