BACKGROUND: To report the radiological and clinical outcomes of internal fixation using distal clavicle hook plates for distal clavicle fractures. METHODS: From April 2008 to December 2012, 32 patients with distal clavicle fractures underwent surgery using an AO hook plate. The reduction was qualified and evaluated according to the radiological findings. The evaluation of the clinical outcomes was performed with the University of California at Los Angeles (UCLA) score, the Korean Shoulder score, and the visual analogue scale (VAS) pain score. RESULTS: By radiological evaluation, we found that 31 of 32 patients showed anatomical reduction and solid bone union. Although we obtained satisfactory UCLA scores, Korean Shoulder Scale scores, and VAS pain scores, 12 cases of complications were present. We found 4 cases of osteolysis of the acromion, 1 case of nonunion, 3 cases of periprosthetic fractures, 3 cases of subacromial pain, and 1 case of skin irritation. We performed re-operations in 2 patients. CONCLUSIONS: To avoid complications associated with clavicle hook plates, choosing the appropriate hook size and bending of the hook according to the slope of the acromion undersurface is critical. Also, we believe that early removal of clavicle plates may help reduce complications.

Acinetobacter species encounters frequently with clinical specimens and now accounts for a substantial proportion of endemic nosocomial infections in Korea. Recent trends indicate that the antimicrobial resistant strains of Acinetobacter species are increasing. Sixty-one strains were isolated from specimens of patients suspected of nosocomial infections during 1991 to 1996. At present, phenotypic identification of Acinetobacter using biochemical test may not be reliable and resulted in the difficulty to clarify the source of infections and epidemiological study of hospital-acquired infections. Aware of the importance of rational taxonomic proposal for these isolates, correct species identification of these organisms by molecular typing method was carried out. A total of fifty-four strains of A. calcoaceticus-A. baumannii complex species which were identified to genospecies 2 and 13 by biochemical characteristics was subjected to identify by ribotyping using restriction endonuclease EcoRI, ClaI, and SalI. Of fifty-four strains, twenty-five strains were identified as A. baumannii (genospecies 2) and twenty-one strains as genospecies 13, and six strains changed to genospecies 3, and the rest two strains were confirmed as A. haemolyticus (genospecies 4). This result suggests that the ribotyping may be of value for identification of genospecies and epidemiological information of Acinetobacter strains.

OBJECTIVES: Causes of diverse clinical sourses of patients with chronic hepatitis B virus(HBV) infection are not fully-known. The host immune response to HBV antigen and the appearance of mutant viruses are believed to be important factors. To determine whether appearance of precore and core mutant viruses are related to the clinical course of the patients, we analysed the entire core region of viral DNA in 7 HBV chronic carriers. METHODS: Serum was obtained from 7 patients(3 chronic active hepatitis, 4 CAH with cirrhosis) and pre-C and core region of HBV were amplified by polymerase chain reaction, then directly sequenced. RESULT: In all 7 HBV DNA there was a point mutation from T to C at nucleotide 2104 of core region, and each DNA also contained 6 to 17 variable point mutations at different nucleotides yielding various amino acid substitution. One of DNA had a point mutation from A to G at nucleotide 1898, converting tryptophan(TGG) to a stop codon(TAG). Two cases of deletion mutations covered C-region segment ranging from nucleotide 2142 to 2306 and one case of deletion covered pre-C region ranging from nucleotide 1815 to 1843. CONCLUSION: Three out of seven DNA contained mutational sites coincided with known immunodominant T cell epitopes and rest of the mutational sites could also affect the antigenecity of the HBV. Therefore, mutant HBV could after the host immune response, and may modulate the clinical course of infection.
