BACKGROUND: This study aimed to investigate bradycardia as an adverse effect after administration of dexmedetomidine during 33degrees C target temperature management. METHODS: A retrospective study was conducted on patients who underwent 33degrees C target temperature management in the emergency department during a 49-month study period. We collected data including age, sex, weight, diagnosis, bradycardia occurrence, target temperature management duration, sedative drug, and several clinical and laboratory results. We conducted logistic regression for an analysis of factors associated with bradycardia. RESULTS: A total of 68 patients were selected. Among them, 39 (57.4%) showed bradycardia, and 56 (82.4%) were treated with dexmedetomidine. The odds ratio for bradycardia in the carbon monoxide poisoning group compared to the cardiac arrest group and in patients with higher body weight were 7.448 (95% confidence interval [CI] 1.834-30.244, p = 0.005) and 1.058 (95% CI 1.002-1.123, p = 0.044), respectively. In the bradycardia with dexmedetomidine group, the infusion rate of dexmedetomidine was 0.41 +/- 0.15 microg/kg/h. Decisions of charged doctor's were 1) slowing infusion rate and 2) stopping infusion or administering atropine for bradycardia. No cases required cardiac pacing or worsened to asystole. CONCLUSIONS: Despite the frequent occurrence of bradycardia after administration of dexmedetomidine during 33degrees C target temperature management, bradycardia was completely recovered after reducing infusion rate or stopping infusion. However, reducing the infusion rate of dexmedetomidine lower than the standard maintenance dose could be necessary to prevent bradycardia from developing in patients with higher body weight or carbon monoxide poisoning during 33degrees C targeted temperature management.

BACKGROUND: There are many rating scales for assessment of geriatrics. But each of these scales were not sufficient to evaluate comprehensive geriatric assessment, physical and psychologic efforts for care. METHODS: We developed new scales to comprehensive geriatric assessment for care of geriatric patients. The Geriatrics Physical Support Scale(GPSS) evaluates physical effort consists of 10 areas and the Geriatrics Global Support Scale(GGSS) evaluates general condition of patients consist of 6 areas. Eighty probable and possible AD patients received the Clinical Dementia Rating Rating Scale(CDR), Korearn version of Mini-Mental State Examination(K-MMSE), Barthel Activity of Daily Living Index(B-ADL) GPSS, GGSS. We tested internal consistency, correlation among dementia rating scales. RESULTS: The GPSS correlated to CDR -0.63(p<0.01), B-ADL -0.90(p<0.01) and the GGSS correlated to CDR -0.60(p<0.01), B-ADL -0.75(p<0.01). The internal consistency were 0.69(GGSS), 0.92(GPSS). CONCLUSION: The Geriatrics Global Support Scale evaluate general condition of patients and the Geriatrics Physical Support Scale evaluate physical efforts needed for care of geriatric patients. These scales an also brief and easy rating scales to grade degree of caregiver`s burden.

BACKGROUND: The purpose of this study was to determine the tibial fixation strength provided by different intraosseous soft tissue graft lengths within the tibial tunnel. METHODS: Porcine tibial bones and digital flexor tendons were used for testing. Bone mineral densities of proximal tibial medial condyles were measured, and two-strand tendon bundles of 8 mm diameter were used. An intraosseous graft length of 2 cm was used in group 1 (n = 10), and a graft length of 4 cm was used in group 2 (n = 10). Tunnels were 4 cm in length and 8 mm in diameter. Tibial fixation was performed using a suture tied around a screw post with a washer and an additionally inserted 7 x 20 mm bioabsorbable screw. After applying preconditioning loading of 10 cycles, 1,000 cycles between 70-220 N were applied at a frequency of 1 Hz. Graft slippage and total graft movement were recorded. Ultimate tensile strength was measured by pull-out testing at an Instron crosshead speed of 1,000 mm/min. RESULTS: No significant intergroup difference was found for total graft movement after cyclic loading (slippage in group 1, 1.2 mm and group 2, 1.2 mm, respectively, p = 0.917; and total graft movement in group 1, 3.3 mm and group 2, 2.7 mm, respectively, p = 0.199). However, mean ultimate tensile strength in group 2 was significantly higher than that in group 1 (group 1, 649.9 N; group 2, 938 N; p = 0.008). CONCLUSIONS: In a porcine model, ultimate tensile strength was greater for a 4 cm long intraosseous flexor tendon in the tibial tunnel. However, no intergroup difference in graft slippage or total graft movement was observed. The results show that a 2 cm intraosseous graft length in the tibial tunnel is safe and has sufficient strength (> 450 N) for adequate rehabilitation after anterior cruciate ligament reconstruction.

There have been very few reports on reflex seizures induced by writing. Complex precipitating behaviors such as calculation, writing, copying of complicated figure, and spatial construction have been recognized as triggering factor of epileptic seizures. We report a case of a patient with a very unusual form of complex reflex epilepsy in which seizures are usually induced by writing or spatial construction. Neurological examination was normal and brain magnetic resonance imaging showed mild brain atrophy without focal lesion. During long-term video-EEG monitoring, she was instructed to write a letter with the right hand. About 20 minutes after writing, she experienced similar aura and motion arrest and then showed an elevation of bilateral upper extremities like myoclonic jerk followed by generalized tonic clonic seizure. On ictal EEG, spike and wave complexes appeared from both centroparietal region followed by 10 Hz rhythmic activities for 20 seconds. Interictal EEG was normal. Ictal-interictal subtraction image of brain SPECT (99mTc-HMPAO) showed hyperperfusion in the middle frontal gyrus and precentral gyrus of left frontal lobe and superior and inferior frontal gyrus of right frontal lobe. We suggest that this reflex epilepsy might be originated from both central areas with maximum on the left side. Oxcarbazepine was effective in controlling this reflex epileptic seizure.

PURPOSE: To evaluate incidentally observed thickened mucosa of paranasal sinuses on brain MRI of patients without evidence of sinusitis. MATERIALS AND METHODS: We reviewed brain MRI of 82 adults aged over 20 ; 45 were males and 37 were females. Brain axial MRI was obtained from the hard palate with 8mm thickness and 2mm gap. The mucosal thickness of incidentally observed paranasal sinuses seen on brain MRI was measured at the mostly thickened portion by T2- and T1-weighted images. RESULTS: The mean mucosal thickness at the most thickened portion of paranasal sinuses, regardless of their location was 3.5mm with S.D. of 1.5mm. The mucosal thickening was observed more commonly in maxillary (79 patients, mean 3.0mm, S.D. 1.4mm) and ethmoid sinuses (80 patients,mean 2.7mm, S.D. 1.1mm) than in sphenoid (39 patients, mean 1.6mm, S.D. 1.4mm) or frontal sinuses (38 patients, mean 1.9mm, S.D. 1.4mm). CONCLUSION: Mucosal thickening of up to 6.5mm was a common finding on brain MRI of patients without evidence of sinusitis ; accuracy was 95%.

We investigated the synergistic apoptotic effects of co-treatments with Chios gum mastic (CGM) and eugenol on G361 human melanoma cells. An MTT assay was conducted to investigate whether this co-treatment efficiently reduces the viability of G361 cells compared with each single treatment. The induction and augmentation of apoptosis were confirmed by DNA electrophoresis, Hoechst staining, and analyses of DNA hypoploidy. Western blot analysis and immunofluorescent staining were also performed to evaluate expression and translocation of apoptosis-related proteins following CGM and eugenol co-treatment. Proteasome activity and mitochondrial membrane potential (MMP) changes were also assayed.The results indicated that the co-treatment of CGM and eugenol induces multiple pathways and processes associated with an apoptotic response in G361 cells. These include nuclear condensation, DNA fragmentation, a reduction in MMP and proteasome activity, an increase of Bax and decrease of Bcl-2, a decreased DNA content, cytochrome c release into the cytosol, the translocation of AIF and DFF40 (CAD) into the nucleus, and the activation of caspase-9, caspase-7, caspase-3, PARP and DFF45 (ICAD). In contrast, separate treatments of 40 microg/ml CGM or 300 microM eugenol for 24 hours did not induce apoptosis. Our present data thus suggest that a combination therapy of CGM and eugenol is a potential treatment strategy for human melanoma.

Tuberculous menigitis is relatively common disease and delay in treatment is associated with many neurologic sequelae. Of the neurologic disorder, diabets insipidus is extreamly rare. Diabetes insipidus is a syndrome characterized by the excretion of abnormally large volumes of dilute urine. It is divided into central diabets insipidus, nephrogenic diabetes insipidus, primary polydipsia and gestational daibetes insipidus. In this four type of diabetes insipidus, central diabetes insipidus is a polyuric disorder results from a lack of sufficient antidiuretic hormone to effect appropriate concentration of the urine for water conservration. We report a 25-year old male who had prolonged head ache and subsequently followed by polyuria. He was dia gonsed as the tuberculous meningitis by laboratory find ing and smear of CSF, and diagnosed central diabetes insipidus by serum osmolality & Na+ & AVP (arginine va sopressin), urine osmolality & specific gravity, adminis tration of vasopressin. He maintained the water balance of body by administration of vasopressin, but without im provement of mental status, sudden cardiac arrest occurs on 20th hospital day

PURPOSE: We evaluate the short-term clinical outcome of arthroscopic rotator cuff tendon repair with suture-bridge technique in patients with full thickness rotator cuff tear. MATERIALS AND METHODS: 29 (male:17, female:12) consecutive shoulders treated with this index procedure and early rehabilitation were enrolled. Mean age was 56.4 years (range, 34~73 years) and mean follow-up period was 13 months (range, 12-15 months). Clinical outcomes were evaluated by using the University of California Los Angeles (UCLA) score, the Korean Shoulder Scoring System (KSS) and Visual Analogue Scale (VAS). Postoperative cuff integrity was evaluated through magnetic resonance imaging (MRI) and categorized by Sugaya classification. RESULTS: Postoperative UCLA scores improved from16.4 to 31.6 (p< 0.05) and KSS scores showed 88 at 6 months and 92 at last follow up. Preoperative VAS score was 8.6, which was decreased to 2.1 at 3 months and 1.4 at 6 months postoperatively. 28 patients (96.5%) had increase in range of motion. The follow up MRI was taken in 15 shoulders and the cuff integrity was type I in 6 cases, type II in 7, type III in 1 and type V in 1 by Sugaya classification. CONCLUSION: Arthroscopic suture-bridge technique resulted in good or excellent clinical outcome in 96.5% of the cases, so we think this technique is one of the reliable procedure for full-thicknes rotator cuff tear.

PURPOSE: Men with documented chronic prostatitis, with elevated serum prostate specific antigen (PSA), were investigated to assess whether treatment lowers serum PSA and thus avoids unnecessary biopsies. MATERIALS AND METHODS: The medical records of 46 men who presented with serum PSA higher than 4ng/ml, and subsequently diagnosed with chronic prostatitis, were retrospectively reviewed. After the administration of antibiotics and anti-inflammatory drugs for 4 to 8 weeks, the follow-up PSA levels were determined, and those with levels higher than 4ng/ml underwent a prostate biopsy. RESULTS: The mean PSA level decreased 61% from 11.66ng/ml before, to 3.79ng/ml after, treatment (p<0.001). In 30 patients the serum PSA level decreased to below 4ng/ml (mean 1.69), with these patients no longer having an indication for a prostate biopsy. In the remaining 16 patients the serum PSA level remained elevated above 4ng/ml, so they underwent a prostate biopsy. Pathological study revealed benign prostatic hyperplasia in 11 cases and prostate cancer in 5. The PSA level in patients associated with benign prostatic hyperplasia decreased 61.9% with treatment, from 19.96 to 7.88ng/ml (p=0.006) and the PSA in those associated with prostate cancer decreased 30.6% with treatment, from 12.85 to 7.32ng/ml (p<0.05). CONCLUSIONS: This study demonstrates that chronic prostatitis can cause elevation of serum PSA levels, and when identified, antibiotics and anti-inflammatory treatment can lower these levels and an unnecessary prostate biopsy can be avoided.
