A novel bacteriophage, designated as VPP97, that infects the strains of Vibiro parahaemolyticus (hallophilic, Gram-negative bacterium) isolated most commonly from marine environments, has been discovered, and several of its properties have been determined. The plaques were clear and sized 0.6-1.0 mm in diameter. The virion forms a single band on 70% sucrose gradient and p1.50 CsC1 gradient by sucrose gradient centrifugation and CsCI gradient centrifugation respectively. It has a hexagonal head and a relatively long tail, as shown by electron microscopy. Vibrio alginolyticus, Vibrio fluvialis and Vibrio furnissii were also sensitive to this phage It was almost totally inactivated at 70 degree C and at pH below 5 or over 10. The nucleic acid of VPP97 is composed of DNA. The VPP97 had 9 specific structural proteins sized between 21.5 kDa and 97.4 kDa on SDS-PAGE. When V. parahaemolyticus cultures were treated with either phage VPP97 or one of the several antibiotics for 2 hours, the viable number of V. parahaemolyticus treated with the phage VPP97 is lower than that treated with chloramphenicol, erythromycin or penicillin, but not lower than that treated with tetracycline. Mice that have responded to the phage treatment revealed the lower numbers of V. parahaemolyticus in small intestine and less damage on small intestine compared to the untreated mice. Therefore, we suggest that the phage treatment appears effective to the infection by V. parahaemolyticus.

BACKGROUND: Although a history of febrile convulsion (FC) is common in epilepsy patients, the preferential associa-tion of febrile convulsion with temporal lobe epilepsy (TLE) is not clear. METHODS:We obtained the FC data from "Paik and Bongsang hospital" epilepsy clinic. We classified epilepsy syndromes into generalized epilepsy (GE), temporal lobe epilepsy (TLE), extratemporal epilepsy (ETLE), unclassified partial and undetermined epilepsy by standardized criteria. The incidence of antecedent FC was evaluated in relation to the epilepsy classifications. We calculated kappa values for inter and intra observer reliability for the classifications of epilepsy syndromes. RESULTS: The agreement of epilepsy classifications were reliable (intra-observer kappa value=0.78, inter-observer kappa value=0.77). Thirteen percent of the studied patients (72/537) had a history of FC and 38% of FC (27/72) were complex types of FC. TLE was more likely to be preceded by FC 25% (42/166) than ETLE 6% (12/189), p<0.05 or GE 13% (12/93), p<0.05 and 85% of complex FC (23/27) preceded TLE. GE however, was more likely to have non-complex FC 100% (12/12) than partial epilepsy 55% (32/58), p<0.05. CONCLUSIONS We therefore conclude and agree that FC should be preferentially associated with TLE.

OBJECTIVE: Panic disorder has been suggested to be divided into the respiratory and non-respiratory subtypes in terms of its clinical presentations. The present study aimed to investigate whether there are any differences in treatment response and clinical characteristics between the respiratory and non-respiratory subtypes of panic disorder patients. METHODS: Among the 48 patients those who completed the study, 25 panic disorder patients were classified as the respiratory subtype, whereas 23 panic disorder patients were classified as the non-respiratory subtype. All patients were treated with escitalopram or paroxetine for 12 weeks. We measured clinical and psychological characteristics before and after pharmacotherapy using the Panic Disorder Severity Scale (PDSS), Albany Panic and Phobic Questionnaire (APPQ), Anxiety Sensitivity Index-Revised (ASI-R), State-Trait Anxiety Inventory (STAI-T, STAI-S), Hamilton Anxiety Rating Scale (HAM-A), and Hamilton Depression Rating Scale (HAM-D). RESULTS: The prevalence of the agoraphobia was significantly higher in the respiratory group than the non-respiratory group although there were no differences in gender and medication between the two groups. The respiratory group showed higher scores on the fear of respiratory symptoms of the ASI-R. In addition, after pharmacotherapy, the respiratory group showed more improvement in panic symptoms than the non-respiratory group. CONCLUSION: Panic disorder patients with the respiratory subtype showed more severe clinical presentations, but a greater treatment response to SSRIs than those with non-respiratory subtype. Thus, classification of panic disorder patients as respiratory and non-respiratory subtypes may be useful to predict clinical course and treatment response to SSRIs.

Korean Journal of Anesthesiology 2020;73(6):518-524
Background:
The effects of anesthetic techniques on postdural puncture backache (PDPB) have not been specifically evaluated. The purpose of this study was to compare the incidence and severity of PDPB between median and paramedian techniques.
Methods:
Patients were randomized to receive spinal anesthesia by either a median (Group M, n = 50) or paramedian (Group P, n = 50) approach.We recorded each patient’s personal number of puncture attempts, surgical position, and operation duration. We investigated the incidence and intensity of back pain 1 day, 1 week, and 1, 2, and 3 months postoperatively.
Results:
The overall incidence of PDPB was higher in the Group M (18/50, 36%) than in the Group P (8/50, 16%) (P =0.023). Twenty-four hours after surgery, 8 patients in Group M and 6 patients in Group P complained of back pain, and the average numeric rating scale (NRS) pain scores showed no evidence of differences. Seven days after the surgery, 16 patients in the Group M and 5 patients in the Group P complained of pain (P = 0.007); their NRS scores did not significantly differ. After 1 month, 5 patients in the Group M and 1 patient in the Group P complained of pain. Only one patient in each group complained of pain after 3 months.
Conclusions
The results of this study suggest that spinal anesthesia using the paramedian approach reduces the incidence of PDPB during the early postoperative period.

Grisel’s syndrome is a non-traumatic atlantoaxial rotatory subluxation for which the underlying mechanism has not yet been identified. It is known to occur following upper respiratory infections, tonsillitis, ear, nose, and throat (ENT) surgeries such as tonsillectomy and adenoidectomy. The diagnosis of Grisel’s syndrome can be made by plain x-ray, CT scanning, and/or MRI scanning. The first choice of treatment is conservative therapy such as bed rest, muscle relaxation, analgesic therapy, antibiotics, and simple traction. While Grisel’s syndrome occurs rarely, delayed treatment may lead to neurological complications or requires surgical treatment. Early diagnosis and treatment are important in preventing fatal outcome. We report the case of a 9-year-old male who developed Grisel’s syndrome after tonsillectomy and adenoidectomy.

Pure dislocation of 1st carpometacarpal (CMC) joint is uncommon and may be missed initially. The neglected dislocation of 1st CMC joint can be reduced by open method and required capsular repair or ligament reconstruction for stability of 1st CMC joint. We experienced the patient with an old dislocation of 1st CMC joint which was recognized 9 months after the injury. Open reduction was impossible, therefore we treated by the trapezial excision and ligament reconstruction tendon interposition arthroplasty, resulting in painless functional joint.

PURPOSE: In this study, brazing characteristics of ZrO2 and Ti-6Al-4V brazed joints with increasing temperature were investigated. MATERIALS AND METHODS: The sample size of the ZrO2 was 3 mm x 3 mm x 3 mm (thickness), and Ti-6Al-4V was 10 mm (diameter) x 5 mm (thickness). The filler metal consisted of Ag-Cu-Sn-Ti was prepared in powder form. The brazing sample was heated in a vacuum furnace under 5 x 10(-6) torr atmosphere, while the brazing temperature was changed from 700 to 800degrees C for 30 min. RESULTS: The experimental results shows that brazed joint of ZrO2 and Ti-6Al-4V occurred at 700 - 800degrees C. Brazed joint consisted of Ag-rich matrix and Cu-rich phase. A Cu-Ti intermetallic compounds and a Ti-Sn-Cu-Ag alloy were produced along the Ti-6Al-4V bonded interface. Thickness of the reacted layer along the Ti-6Al-4V bonded interface was increased with brazing temperature. Defect ratios of ZrO2 and Ti-6Al-4V bonded interfaces decreased with brazing temperature. CONCLUSION: Thickness and defect ratio of brazed joints were decreased with increasing temperature. Zirconia was not wetting with filler metal, because the reaction between ZrO2 and Ti did not occur enough.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 2007;34(3):314-318
PURPOSE: Pressure sore wound develops inevitably in long-term, immobilized and hospitalized patients. Sore wound infection is common problem and makes healing process difficult. We aimed to identify the pathogens of the purulent discharge in sore wound and to obtain information for appropriate antibiotics through a sensitivity test METHODS: The bacteriologic study was made on 120 cases of patients who admitted or visited our hospital from 2004 January to 2005 December for sore wound treatment. Culture material was collected in BBL transport media with cotton swab and cultured by MacConkey agar plate. The method of MIC by VITEK and Microscan was used for sensitivity test. RESULTS: Among 120 specimens, organisms were isolated from 77(64.2%) cases. Gram positive organisms were cultured in 73 specimens, Gram negative organisms in 46 specemens, and fungi in 2 specimens. Mixed infection by Gram (+) and Gram (-) bacteria were observed in 34 specimens. Among them, S. aureus was the most common isolate in 24(31.2%) patients and 10 (13.0%) S. Aureus isolates were MRSA. The most prevalent Gram-negative organism was Escherichia coli in 20 patients(25.9%). Vancomycin and teicoplanin showed highest sensitivity to Gram-positive organisms and imipenem and amikacin to Gram-negative organisms. CONCLUSION: Pressure sore wound demands consideration of multimodal therapeutic aspects and these findings would be useful informations to physicians, nurses and clinical assistants in understanding the nature of sore wound and selecting appropriate antibiotics.
