BACKGROUND: We evaluated the effectiveness of isolation measures using cohorting rooms and antimicrobial use in reducing the isolation rate of methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Acinetobacter baumannii (MDR-AB). METHODS: Four cohorting rooms (16 beds) for patients colonized or infected with multidrug-resistant organisms (MDRO) have been created in the general wards of our 894-bed hospital since October 2003. We prospectively evaluated the isolation rates of MRSA and MDR-AB, and amount of antimicrobial use during the 8-year study period. We also investigated the relationship between antimicrobial use density (AUD) and the isolation rates of MRSA and MDR-AB. RESULTS: After creating cohorting rooms, the isolation rates of MRSA decreased from 1.56 cases per 1,000 patient-days from 2004-2005 to 1.24 from 2006-2007 (P=0.57). The isolation rates of MDR-AB also decreased from 0.72 from 2004-2005 to 0.36 from 2010-2011 (P<0.01). The mean quarterly AUDs of glycopeptides and carbapenems were 30.17+/-6.80 and 19.5+/-7.10, respectively. There were no significant correlations between AUD values and the isolation rate of MRSA or MDR-AB. CONCLUSION: This study suggests that isolation measures using cohorting rooms to help limit the transmission of MDRO infection and colonization, especially MDR-AB, in resource-limited settings is feasible and efficacious.

For the physical characterization of neutron beam, dosimetric measurements had been performed to obtain physical data of KCCH cyclotron-produced neutrons for clinical use. The results are presented and compared with the data of other institutions from the literatures. The central aixs percent depth dose, build-up curves and open and wedge isodose curve values are intermediate between that of a 4 and 6 MV X-ray. The build-up level of maximum dose was at 1.35 cm and entrance dose was approximately 40%. Flatness of the beam was 9% at Dmax and less than+/-3% at the depth of 80% isodose line. Penumbra begond the 20% line is wider than corresponding photon beam. The output factors ranged 0.894 for 6 x 6 cm field to 1.187 for 30 x 30 cm field. gamma contamination of neutron beam was 4.9% at 2 cm depth in 10 x10 cm field.

OBJECTIVE: Incidence of chronic subdural hematoma (CSDH) is gradually increasing in young adults for several reasons. In this study, we aimed to identify features of CSDH noted in young adults that distinguish the disease from CSDH diagnosed in the elderly. METHODS: One hundred eighty-two patients with CSDH who underwent a total of 218 surgical procedures between January 2003 and February 2010 were retrospectively reviewed with regard to clinical presentation, radiographic results and prognosis including recurrence. To compare younger patients with the elderly, patients were divided into three groups on the basis of age (Group A: < or =40, Group B: 41-64, Group C: > or =65 years). RESULTS: Group A showed a male predominance (p=0.0001), lower rate of recurrence (p=0.0012), shorter symptom duration (p=0.035), and fewer leading signs such as hemispheric symptoms (p=0.005) compared to Groups B and C. Radiologic findings such as maximal hematoma thickness (p<0.0001) and degree of midline shift (p=0.028) were less severe in Group A than Groups B and C. Alcoholism was the most prevalent illness in all three groups. When exempting infants with hematologic malignancy, non-recurrence, previous trauma history, headache as leading symptom, and no mortality were all common in younger adults (all p<0.05). CONCLUSION: Young adults with CSDH show less severe clinical and radiologic features as well as fewer recurrences than noted in the elderly population. Even if a clinician's index of suspicion of CSDH in young adults complaining of headache is not high, meticulous radiologic surveillance could find CSDH, leading to satisfactory results including less frequent recurrence.

Posterior interosseous nerve(PIN) syndrome is an entrapment of the deep branch of the radial nerve just distal to the elbow joint. It is caused by acute trauma or masses compressing the nerve. We report an unusual case of PIN syndrome with wrist drop caused by compression of the nerve by anomalous vascular leash. The patient has recovered with the surgical decompression of the offending vessels and arcade of Frohse.

OBJECTIVE: Recently, the definition of occult osteoporotic vertebral fracture has been established, and its clinical significance has come to our interest. We report the effect of early percutaneous vertebroplasty in occult osteoporotic vertebral fracture. METHODS: From January 2006 to January 2008, we performed percutaneous vertebroplasty for 50 levels in 47 patients. 21 levels (21 patients) of them were classified into occult osteoporotic vertebral fracture group, 29 levels (26 patients) were categorized into control group (not occult osteoporotic vertebral fracture) by the Pham T..s criteria. We obtained VAS score and measured the compression ratio at first hospital day and 1 day, 1 month, 3 months after procedure. RESULTS: There are noticeable improvements in VAS score. The mean VAS score at admission was 6.44 in occult group and 6.15 in control group, which changed 2.23 in occult group and 2.68 in control group after procedure. The compression rate was 1.008, 1.018, 1.016 in occult group and 0.862, 0.891, 0.881 in control group at admission and 1 month, 3 months after procedure. The conservative effect for vertebral height was higher than control group (p=0.011). CONCLUSION: Percutaneous vertebroplasty in occult osteoporotic compression fracture provided significant pain relief and conservative effect for vertebral height. It is probable that it can lower the rate of secondary adjacent vertebral compression fracture.

Vasospasm has been known as one of the most potent causes of delayed ischemic neurologic deficits (DINDs) after aneurysmal subarachnoid hemorrhage (SAH). An established effective therapy for vasospasm has been used in preventing cerebral ischemia. Nevertheless, several reports suggested the possibility that there may be other causes of DINDs from the cases which couldn't be explained by hemodynamic vasospasm. Authors experienced two cases of thromboembolic infarction as a cause of DINDs after aneurysmal SAH. We propose that thromboembolism can be a considerable cause of DINDs independent of hemodynamic vasospasm.

Approximately one-third of patients with Crohn's disease do not respond to conventional treatments, and some experience significant adverse effects, such as serious infections and lymphoma, and many patients require surgery due to complications. Increasing evidence suggests that specific changes in the composition of gut microbiota, termed as dysbiosis, are a common feature in patients with inflammatory bowel disease (IBD). Dysbiosis can lead to activation of the mucosal immune system, resulting in chronic inflammation and the development of mucosal lesions. Recently, fecal microbiota transplantation, aimed at modifying the composition of gut microbiota to overcome dysbiosis, has become a potential alternative therapeutic option for IBD. Herein, we present a patient with Crohn's colitis in whom biologic therapy failed previously, but clinical remission and endoscopic improvement was achieved after a single fecal microbiota transplantation infusion.

OBJECTIVE: Acute cerebral infarction is often accompanied by transtentorial herniation which can be fatal. The aim of this study is to determine the timing of surgical intervention and prognostic factors in patients who present with acute cerebral infarction. METHODS: We reviewed retrospectively 23 patients with acute cerebral infarction, who received decompressive craniectomy or conservative treatment from January 2002 to December 2004. We divided patients into two groups according to the treatment modalities (Group 1: conservative treatment, Group 2: decompressive craniectomy). In all patients, the outcome was quantified with Glasgow Outcome Scale and Barthel Index. RESULTS: Of the 23 patients, 11 underwent decompressive craniectomy. With decompressive craniectomy at the time of loss of pupillary light reflex, we were able to prevent death secondary to severe brain edema in all cases. Preoperative Glasgow Coma Scale and loss of pupillary light reflex were significant to the clinical outcome statistically. With conservative treatment, 9 of the 12 patients died secondary to transtentorial herniation. The clinical outcomes of remaining 3 patients were poor. CONCLUSION: This study confirms the value of life-saving procedure of decompressive craniectomy after acute cerebral infarction. We propose that the loss of pupillary light reflex should be considered one of the most important factors to determine the timing of the decompressive craniectomy.

OBJECTIVE: Neurosurgeons occasionally advocated intraoperative ventriculostomy to prevent traumatic brain retraction because of severe brain swelling in an acute stage of aneurysmal subarachnoid hemorrhage (SAH) surgery. The authors investigated the impact of the intraoperative ventriculostomy on the occurrence of shunt-dependent hydrocephalus in acute SAH. METHODS: The data of 141 ruptured aneurysm patients who underwent aneurysmal neck clipping in an acute stage were retrospectively reviewed. The patients were divided into three groups according to the cerebrospinal fluid (CSF) drainage amount via intraoperative ventriculostomy. Group 1 (n=44) included the patients who were not performed the intraoperative ventriculostomy, Group 2 (n=34) consisted of patients who were drained the CSF less than 40 cc (< 40 cc) via intraoperative ventriculostomy, and Group 3 (n=63) drained the CSF more than 40 cc (> or = 40 cc). By using statistical methods, the authors analyzed the influences of various variables including Hunt-Hess grade, Fisher grade, Glasgow coma scale, Glasgow outcome scale, presence of acute hydrocephalus and intraventricular hemorrhage (IVH) at admission on the occurrence of hydrocephalus. And also, we analyzed the relationships among the cisternal drainage, lamina terminalis fenestration, and the shunt-dependent hydrocephalus. RESULTS: Concerning the amount of CSF drainage via intraoperative ventriculostomy, the incidence of shunt-dependent hydrocephalus did not show any difference in three groups (p=0.146). Presence of the acute hydrocephalus, lamina terminalis fenestration, and cisternal drainage did not exert any influence on the incidence of shunt-dependent hydrocephalus, respectively (p=0.124, p=0.168, p=0.452). However, the incidence of shunt-dependent hydrocephalus in patients who had IVH at admission was significantly higher than in who did not have (p=0.010). CONCLUSIONS: Routine intraoperative ventriculostomy dose not increase the incidence of shunt-dependent hydrocephalus. Moreover, it obtains an adequate intraoperative brain relaxation, which results in the decrease of the brain retraction injury and the operation time.
