The pulmonary cavernous hemangioma is usually from birth and there may be without symptoms until adulthood. Larger or multiple pulmonary angiomata with considerable pulmonary arteriovenous shunts may cause cyanosis, finger clubbing, dyspnea and frequently accompanyingbruit. Recently, we experienced a case of cavernous hemangioma of the lung. A 34-year-old woman was admitted to our hospital for surgical evaluation of a 4 cm solitary, round nodule in the right upper lobe on the chest X-ray and CT scan. She had no symptoms. Laboratory findings are within normal limits except for elevated glucose levels. At surgery, the mass was well encapsulated and easily excised from the peripheral portion of the posterior segment of the right upper lobe. Grossly, it consisted of a 4 cm in diameter, round, soft, sponge-like, hemorrhagic, slightly lobulated mass with a smooth external surface. Microscopically, the mass was composed of vessels, which were thin walled, dilated and filled with blood. The wall of the abnormal vessels was thin and composed of endothelium and fibrous connective tissue with only a little smooth muscle. Immunohistochemically, the wall of the dilated abnormal vessesls showed negative reaction for cytokeratin(low and high) and epithelial membrane antigen but weakly positive reaction for UEA-1 in focal areas.

Recently, next generation sequencing (NGS) has received attention as the ultimate genotyping method to overcome the limitations of capillary electrophoresis (CE)-based short tandem repeat (STR) analysis, such as the limited number of STR loci that can be measured simultaneously using fluorescent-labeled primers and the maximum size of STR amplicons. In this study, we analyzed 15 autosomal STR markers via the NGS method and evaluated their effectiveness in STR analysis. Using male and female standard DNA as single-sources and their 1:1 mixture, we sequentially generated sample amplicons by the multiplex polymerase chain reaction (PCR) method, constructed DNA libraries by ligation of adapters with a multiplex identifier (MID), and sequenced DNA using the Roche GS Junior Platform. Sequencing data for each sample were analyzed via alignment with pre-built reference sequences. Most STR alleles could be determined by applying a coverage threshold of 20% for the two single-sources and 10% for the 1:1 mixture. The structure of the STR in each allele was accurately determined by examining the sequences of the target STR region. The mixture ratio of the mixed sample was estimated by analyzing the coverage ratios between assigned alleles at each locus and the reference/variant ratios from the observed sequence variations. In conclusion, the experimental method used in this study allowed the successful generation of NGS data. In addition, the NGS data analysis protocol enables accurate STR allele call and repeat structure determination at each locus. Therefore, this approach using the NGS system will be helpful to interpret and analysis the STR profiles from singe-source and even mixed samples in forensic investigation.

Purpose:
This study assessed the results of surgical treatment for Neer type-II and type-V unstable distal clavicle fractures via hybrid fixation with a locking compression plate and finger trap wire.
Materials and Methods:
From September 2016 to April 2018, 15 patients treated for Neer type-II and type-V unstable distal clavicle fractures using hybrid fixation were analyzed retrospectively. The clinical results were analyzed based on the radiological healing time, range of motion of the shoulder joint, American Shoulder and Elbow Society (ASES) score, and the University of California at Los Angeles (UCLA) shoulder score.
Results:
The range of motion of the shoulder joint completely recovered to the normal range within 9.2 weeks on average (6−24 weeks). Furthermore, the follow-up of the clinical trial showed excellent results, including an ASES score of 98.5±2.3 and an UCLA score of 34.2±1.3. In addition, fracture union was successfully achieved in all cases, and was identified during week 15 on average.
Conclusion
For the treatment of unstable distal clavicle fractures, hybrid fixation is a useful surgical method with excellent clinical outcomes through rapid recovery of the range of motion of the shoulder joint after surgery.

PURPOSE: The purpose of the study is to investigate the correlation between the symptoms and the incidence of anatomical variant without mucosal abnormality. MATERIALS AND METHODS: Out of 892 patients with CT performed for the evaluation of sinus disease symptoms between March 1991 and March 1993, we observed the anatomic variations in 82 symptomatic patients without mucosal abnormality(male:female=43:39, mean age 36. 4 years). The control group included 88 patients with facial bone CT performed for the evaluation of trauma during the same period while patients with recent paranasal sinusitis were excluded. (male:female=76:12, mean age 22. 4 years). The scouis were performed with 5-ram section thickness from posterior margin of sphenoid sinus to anterior margin of posterior ethmoid and then with 3 mm thickness from anterior margin of posterior ethmoid to anterior margin of frontal sinus. The artatomic variations included nasoseptal deviation, concha bullosa, Hailer cells, Agger nasi cells, etc. RESULTS: The anatomic variations were demonstrated in 71 our of 82 symptomatic patients(86. 5%), whereas they were seen 26 of 88 patients(29. 5%) in control group. CONCLUSION: Our data suggest that there is a possible causal relationship between anatomic variations and symptomas. Even though without accompaning mucosal abnormalities, anatomic variations could contribute simply to its symptomas. ^natomic variants may obstruct or narrow the airway, leading to turbulating air flow or interrupting ucociliary movement, and finally may produce a series os symptoms.

STATEMENT OF PROBLEM: A number of studies about the nano-treated surfaces of implants have been conducting along with micro-treated surfaces of implants. PURPOSE: The purpose of this study was to get information for the clinical use of nano-treated surfaces compared with micro-treated surfaces by measuring removal torque and analyzing histological characteristics after the placement of various surface-treated implants on femurs of dogs. MATERIAL AND METHODS: Machined surface implants were used as a control group. 4 nano-treated surface implants and 3 micro-treated surface implants [resorbable blast media surface (RBM), sandblast and acid-etched surface (SAE), anodized RBM surface] were used as experimental groups. Removal torque values of implants were measured respectively and the histological analyses were conducted on both 4weeks and 8weeks after implant surgery. The surfaces of removed implants after measuring removal torque values were observed by scanning electron microscopy (SEM) at 8 weeks. RESULTS: 1. Removal torque values of the nano-treated groups were lower than those of micro-treated groups. 2. Removal torque values were similar in the anodized RBM surface groups. 3. On the histological views, there was much of bone formation at 8 weeks, but there was no difference between 4 and 8 weeks, and between the types of implant surfaces as well. CONCLUSION: It is suggested that implant topography is more effective in removal torque test than surface chemistry. To get better clinical result, further studies should be fulfilled on the combined effect of surface topography and chemistry for the implant surface treatments.

Granulocytic sarcoma is an uncommon extramedullary localized tumor composed of granulocytic precursor cells. The majority of cases have been reported in association with acute myeloid leukemia(AML) especially in children, but infrequently may occur in patients with myeloproliferative disorders or myelodysplastic syndromes. Most common sites of involvement were bone, soft tissue, lymph nodes and skin, but gastrointestinal tract, testis, central nervous system are also involved rarely. We present an unusual case of granulocytic sarcoma of the intracranium and the retro-orbital soft tissue occurring in a patient with concurrent myelodysplastic syndrome, diagnosed by brain magnetic resonance images and ultrasound guided needle biopsy.
