BACKGROUND: The purpose of this study was to investigate the outcomes after fixation using a 3.5-mm locking compression plate (LCP) hook plate for isolated greater tuberosity (GT) fractures of the proximal humerus. METHODS: We evaluated the postoperative radiological and clinical outcomes in nine patients who were followed up at least 1 year with isolated GT fractures. Using the deltopectoral approach, we fixed the displaced GT fragments with a 3.5-mm LCP hook plate (Synthes, West Chester, PA, USA). Depending on the fracture patterns, the hook plate was fixed with or without augmentation using either tension suture or suture anchor fixation. RESULTS: All the patient showed successful bone union. The mean time-to-union was 11 weeks. The radiological and clinical outcomes at the final follow-up were generally satisfactory. The mean visual analogue scale for pain, the University of California at Los Angeles score, the American Shoulder and Elbow Surgeons score, and the subjective shoulder value were 1.4, 30.3, 84.3, and 82.2%, respectively. The mean active forward flexion, abduction, external rotation, and internal rotation of the shoulder were 156.7°, 152.2°, 61.1°, and the 10th thoracic vertebral level, respectively. Only one patient presented with a postoperative complication of shoulder stiffness. The patient was treated through arthroscopic capsular release on the 5th postoperative month. CONCLUSIONS: We conclude that fixation using 3.5-mm LCP hook plates for isolated GT fractures of the proximal humerus is a useful treatment method that provides satisfactory clinical and radiological outcomes.

BACKGROUND: Discrepancies exist in the existing researches regarding the association between social capital and self-efficacy, and most of these researches have been done in developed countries. The aims of this study were to assess the independent association between individual social capital and self-efficacy and to assess the associations between individual social capital, self-efficacy and self-rated health. METHODS: Data were obtained from the Gyeongnam health survey (6,500 persons) conducted in 2008. A self-administered questionnaire was additionally administered to gather information on demographic variables, health behaviors, chronic diseases, self-efficacy, social capital, and self-rated health status. Total study population was 3,843 as those with chronic diseases were excluded. RESULTS: In males, trust was positively associated with confidence and preference to task difficulty, and participation was negatively associated with confidence and positively associated with regulation and preference to task difficulty. In females, trust was positively associated with confidence and preference to task difficulty and negatively associated with regulation. Participation was positively associated with preference to task difficulty. In males, the odds for self-rated health status was better for persons with confidence (95% confidence interval, CI 1.088-1.705), trust (95% CI 1.172-1.821) and participation (95% CI 1.268-2.117). In females, the odds for self-rated health status was better for those with confidence (95% CI 1.250-1.803), preference of task difficulty (95% CI 1.019-1.683) and participation (95% CI 1.024-1.555). CONCLUSIONS: High social capital measured at an individual level may promote self-efficacy and health status.

3.The Treatment Results in Site of Tibia Fracture Treated with Interlocking Intramedullary Nail.
Keimyung Medical Journal 2014;33(1):10-15
Intramedullary nailing is the treatment of choice for most diaphyseal fractures of the tibia. The purpose of this study is to evaluate the result of tibia fractures treated with interlocking intramedullary nail, according to different sites of fractures. From september 2004 to august 2012, 106 cases of tibia fracture with a minimum follow up until bony union were selected and analyzed retrospectively. The mean follow-up period of the patients was 24.5 months. The location of fractures were divided into three groups, proximal (n = 18), mid (n = 42), distal (n = 46). Delayed union, mal-alignment and additional operation were investigated. The number of angle change over 5 degrees in the coronal plane and 10 degrees in the sagittal plane were 7 cases in proximal, 7 cases in mid, and 12 cases in distal with statistic significance. And an additional operation was required in 6 patients in proximal fracture, 2 patients in mid fracture, and 7 patients in distal fracture during bony union. Conclusively, intramedullary nailing in proximal and distal tibia fracture showed higher delayed union rate and could result in excessive angle change due to mal-alignment. Therefore, proximal level or distal level tibia fractures need more accurate reduction of fracture than midshaft level would need more accurate reduction of fracture and observe bony union through regularly radiography examination.

PURPOSE: To evaluate the characteristics and relationship between peripapillary choroidal thickness (pCT), lamina cribrosa thickness (LCT), and peripapillary outer retinal layer thickness (pORT) as determined using spectral domain optical coherence tomography (SD-OCT) enhanced depth imaging (EDI). METHODS: In total, 255 participants were included (87 healthy subjects, 87 glaucoma suspects (GS), and 81 glaucoma cases). The pORT, defined as the thickness between the posterior outer plexiform layer and the retinal pigment epithelium (RPE) interface, and the pCT, between the outer margin of the RPE and the choroidal-scleral interface, were manually measured using EDI scanning of the circumpapillary retinal nerve fiber layer (RNFL). LCT was determined by EDI scanning of the optic nerve head (ONH). Baseline characteristics, including axial length (AXL) and the SD-OCT measurements of the participants, were compared among the three groups. The correlation between putative factors and pCT was determined using univariate and multivariate linear regression analyses. RESULTS: In all three groups, both pORT and pCT were thinnest in the inferior area among the four quadrants. In the healthy group, the mean peripapillary RNFL, pORT, and LCT were significantly greater in comparison with those of the GS and glaucoma groups (p < 0.001, p < 0.038, and p < 0.001, respectively). The pCT demonstrated no significant differences among the three groups (p = 0.083). Only age and AXL were associated with pCT by multivariate analysis. CONCLUSIONS: The pCT is substantially thinner in the inferior area of the ONH. In addition, the pCT demonstrates the strongest correlation with age and AXL, but was not associated with glaucoma or LCT.

PURPOSE: To investigate the clinical characteristics of first-degree relatives with primary open-angle glaucoma (POAG). METHODS: Forty-four POAG patients (22 pairs of eyes from 2 first-degree relatives) were followed for an average of 3.3 years. Baseline characteristics and follow-up data were analyzed. Baseline data consisted of baseline intraocular pressure (IOP), central corneal thickness (CCT), spherical equivalent, visual field mean deviation (VF MD) and average retinal nerve fiber layer (RNFL) thickness measured using optical coherence tomography (OCT). Follow-up data consisted of mean follow-up IOP, mean IOP reduction from baseline (%) and progression rates determined by linear regression analysis of either VF MD value or OCT RNFL thickness. Mean data of both eyes and the worse eye were compared between first-degree relatives of the same family. RESULTS: Among the 22 families, 16 pairs of eyes were from parent/offspring and 6 from siblings. No difference in mean baseline IOP and CCT were found between first-degree relatives. The older patients in parent-offspring families showed significantly more advanced glaucoma in terms of both VF and RNFL thickness, but were less myopic; however, no differences in variables were found between relatives in the 6 families composed of siblings. Among the 22 families, worse baseline VF MD was observed in younger patients compared with the older patients in 4 families. Mean follow-up IOP, mean IOP reduction from baseline, and progression rate did not differ between the older and the younger patient in each family. CONCLUSIONS: In our study, similar characteristics in terms of baseline IOP, IOP response to medication, and glaucoma progression rate were found in members of the same family. However, in some of the families, the younger patient had poorer baseline severity and more aggressive characteristics compared with the older patient, suggesting the clinical course of the disease may vary among first-degree relatives.

Retrospective analysis of 46 patients with intracerebral hematoma showed that the attack was most frequent in sixth decade and more prevalent in female. The most common cause of the attack was hypertension(80%) and the site of hemorrhage was putamen 32%, thalamic area 15%, subcortical area 7%, cerebellum 17%, ventricle 3%, and brain stem 4%. Mortality of total cases was 36% and there was no difference of mortality in both conservatively or operatively treated group(38% in conservative group, and 35% in operative group). The prognosis of the patient was unfavorable in the group of poor pretreatment Glasgow coma scale(GCS) and those of cases demonstrated more than 30cc of hematoma on computerized tomography(CT) of the brain. The improvement of GCS after management was better in operative group than in the conservative group.

The surgical results of 1500 patients with intracranial aneurysms operated in the neurosurgical department of our university hospital during the 17 year period from 1978 to 1994 were analysed with regard to the preoperative neurological status, preoperative CT findings and timing of surgical intervention. On the follow up examinations taken between 6 months to 9 years after operations, 1115 patients(74.3%) were classified as those having a good recovery, but 206 patients(13.7%) and 88 patients(5.9%) suffered some morbidity(fair and poor outcome respectively), and 91 patients(6.1%) died. Surgical results for the patients with good neurological status at admission were generally good: good outcome for the patients with Hunt and Hess grade 1 was 87.8% and that for those with grade 2 was 80.9%, while it was 29.6% and 6.7% for patients with grade 4 and 5, respectively. There was no difference of the rate of good outcome between early(0 to 3 days after bleeding) and late surgery(14 days or more after subarachnoid hemorrhage) groups, if poor graded cases were excluded from the early surgery group. Outcome was worse if the surgery was performed during the period between 4th and 10th days after initial bleeding. The major causes of unfavorable outcome(poor and dead) were initial hemorrhagic insults and delayed ischemic deficits. For further improvement of the overall surgical outcome, several factors must be concerned. First, early surgical intervention is recommended in good grade patients on admission but it should probably be delayed in patients with poor grades. Second, active management of poor grade patients should be scrutinized. Third, incidence of delayed ischemia may be lowered with positive consideration and preventive treatment towards vasospasm.

Background:
Pheochromocytoma and paragangliomas (PPGL) are hereditary in approximately 30% to 40% cases. With the advancement of genetic analysis techniques, including next-generation sequencing (NGS), there were attempts to classify PPGL into molecular clusters. With NGS being applied to clinical settings recently, we aimed to review the results of genetic analysis, including NGS, and investigate the association with clinical characteristics in Korean PPGL patients.
Methods:
We reviewed the medical records of PPGL patients who visited Severance hospital from 2006 to 2019. We documented the clinical phenotype of those who underwent targeted NGS or had known germline mutations of related genes.
Results:
Among 57 PPGL patients, we found 28 pathogenic germline mutations of susceptibility genes. Before the targeted NGS was implemented, only obvious syndromic feature lead to the Sanger sequencing for the specific genes. Therefore, for the exact prevalence, only patients after the year 2017, when targeted NGS was added, were included (n=43). The positive germline mutations were found in 14 patients; thus, the incidence rate is 32.6%. Patients with germline mutations had a higher likelihood of family history. There were significant differences in the type of PPGLs, percentage of family history, metastasis rate, presence of other tumors, and biochemical profile among three molecular clusters: pseudohypoxic tricarboxylic acid cycle-related, pseudohypoxic von Hippel-Lindau (VHL)/endothelial PAS domain-containing protein 1-related, and kinase-signaling group. Germline mutations were identified in seven PPGL-related genes (SDHB, RET, VHL, NF1, MAX, SDHA, and SDHD).
Conclusion
We report the expected prevalence of germline mutations in Korean PPGL patients. NGS is a useful and accessible tool for genetic analysis in patients with PPGLs, and further research on molecular classification is needed for precise management.
