Purpose: To report our experience of treatment of rotator cuff tear and evaluate the mid-term outcome. Materials and Methods: We have performed 50 cases of mini-open rotator cuff repair from March 1996 to March 1999. Male to female ratio was 34：16, the average age 46.5(23∼57) years old, mean follow-up period was 78(62∼93) months. All-arthroscopic repair and open repair cases were excluded. Mean symptomatic period was 12.5(6∼38) months, operation was indicated in cases of no improvement by 6 months of conservative management. Preoperative simple radiographs and Magnetic resonance arthrography were obtained in all cases. We also observed the inflammation, synovitis, thickness of tear and associated pathology intraoperatively. We evaluated pain, function, and range of motion by UCLA score. Results: Overall UCLA score was mean 29.5 points. Excellent 25, good 18, poor 7 cases. Mean pain score was improved 2.6 to 7.5, 44 cases(88%) were improved and 6 cases(12%) were not improved. Mean functional score was improved 3.4 to 8.5, and activity at follow up, 25 cases(50%) were same, 8 cases(14%) were above, 17 cases(34%) were below compared with preoperative level. Mean active forward flexion was preoperative 112° to postoperative 160°, forward flexion strength was improved 3.8 to 4.7. 43 cases(86%) of patients were satisfied at the result, 7 cases(14%) were not satisfied or aggravated. Results: Mini-open rotator cuff repair was effective method in treating rotator cuff tear.

Background: Geladas (Theropithecus gelada), endemic to Ethiopia, are distributed closely related to the escarpments and gorge systems of the country, and large populations are found in the Simien Mountain National Park. This study was conducted in Eastern Tigray, Northern Ethiopia, from February 2018 to August 2019 in order to determine population size and composition of geladas. Total count method was used to estimate the population structure of geladas. Observations of the group of geladas based on body size and morphological characteristics were used to classify age and sex categories of the population. SPSS Version 20 was used to analyze the data. Chi-square test was used to compare sex ratio of geladas and population size among the counting sites between wet and dry seasons. Results: A total of 112 and 99 individual of geladas were counted during wet and dry seasons, respectively. Of the average gelada population recorded in this study, 11.4% were adult males, 30.3% were adult females, 12.8% were sub-adult males, 25.6% were sub-adult females, and 19.9% were unidentified juveniles. However, there was no statistically significant difference among the various age and sex groups of geladas counted during wet and dry season (χ² = 2.6, DF = 4, P > 0.05). Variations of group size along seasons were observed in this study. Sex ratio of adult male to adult female was 1:2.6 and 1:2.7 during the dry and wet seasons, respectively. Conclusion: Very small gelada population size was recorded in the current study. An average of 105.5 geladas was recorded during the study period. As this is the first report of gelada population in escarpments of Eastern Tigray, population trend of the geladas cannot decide based on the current study.

Objective : The treatment of giant cell tumor (GCT) is mainly performed surgically. However, GCT in spine seems difficult to treat because of the limited surgical accessibility and proximity. In this report, we analyzed the outcome of GCT treatment in spine. Methods : Between 2000 and 2012, 19 patients received treatment for GCT in spine. Median age at their first diagnosis was 31 years, 10 patients were male, and 9 female. Fourteen tumors were located in the sacrum, 1 in cervical, 1 in thoracic and 3 in lumbar spine. As primary treatment, gross total removal (GTR) was done in 6 patients, and subtotal removal (STR) in 13 patients. Radiation therapy (RT) as an adjuvant therapy was performed in 2 cases in GTR group and 10 cases in STR group. Results : During the follow-up, 7 patients had local recurrence (36.8%). The average period until recurrence after primary treatment was 14 months. No recurrence was detected in GTR group. Recurrence was noted in 7 out of 13 patients who underwent STR. These differences were statistically significant (p=0.024). A median of recurrence free period (RFP) was 84 months. Also average RFP of the RT group was 112 months, and non-RT group was 65 months. These differences were statistically significant (p=0.041). Conclusion : Treatment of choice for GCT in spine is a complete removal of tumor without neurological deficits. In case of incomplete removal, radiation therapy may be a useful adjuvant treatment modality.

A 16-month old boy was referred to our hospital for evaluation of recurrent generalized tonic clonic seizures. Metabolic evaluation revealed significant hyperammonemia ($1,112\;{\mu}g/dl$). Amino acid/acylcarnitine screening using tandem mass spectrometry showed markedly increased plasma levels of citrulline ($1,350\;{\mu}M/l$) with undetectable levels of arginine and arginosuccinic acid. Urinary excretion of citrulline was markedly increased ($38,617\;{\mu}M/g$ creatinine). Brain MRI findings showed diffuse high-signal intensity lesions, that involved gray and white matter in both frontal lobes and insula with edematous changes; these findings were consistent with the acute stage of citrullinemia (CTLN). Mutation analysis of the argininosuccinate synthetase (ASS) gene, in this patient, showed a Gly324Ser mutation in exon 13, and a 67-bp duplication mutation in exon 15 (c.1128-6_1188dup67). The patient was confirmed as having late-onset CTLN1 and treated with anticonvulsants, lactulose enema, protein restricted diet and arginine. Here we describe a case of late-onset CTLN1 in a patient by biochemical analyses and ASS gene mutation confirmation. This is the first report of a Korean patient with late-onset CTLN1 confirmed by ASS gene mutation identification.

Objectives : The aim of this study was to investigate whether and how the symptoms of adult attention deficit hyperactivity disorder (ADHD) affect the stress and depressive symptoms in Korean soldiers. Methods : Data were collected on 131 subjects through self-report using the Korean Adult Attention-Deficit/Hyperactivity Disorder Scale (K-AADHDS), Center for Epidemiological Studies Depression Scale (CES-D), Korean Wender Utah Rating Scale (K-WURS), and the Brief Encounter Psychosocial Instrument (BEPSI-K). Student t-tests, Pearson Correlation, Logistic regression, and Path analysis were performed. Results : The scores related to adult ADHD symptoms on the K-AADHDS and K-WURS were correlated with stress scores on the BEPSI-K (r=0.529, p<0.001 and r=0.484, p<0.001) and with depressive symptoms on the CES-D (r=0.686, p<0.001 and r=0.628, p<0.001). Scores related to adult ADHD on the K-AADHDS were the most significant risk factors for stress (O.R=1.198, 95% CI=1.104-1.299), and depressive symptoms (O.R=1.306, p95% CI=1.112-1.534). Path analysis on depressive symptoms showed that adult ADHD symptoms affected stress and depressive symptoms. Conclusion : The results suggest that it may be important to consider the evaluation and treatment of adult ADHD in soldiers. Prospective studies with larger numbers of subjects are warranted to further explore the relevance of the present results.

It is rare for low-grade gliomas to disseminate to the leptomeninges. However, low-grade gliomas with dissemination to the leptomeninges have been occasionally reported in children, and have generally been associated with local recurrence. A 16-year-old boy sought evaluation for diplopia and gait disturbance. A brain magnetic resonance imaging (MRI) revealed pontine mass, which was proved to be fibrillary astrocytoma on biopsy, later. Radiation therapy (5400 cGy) was given and the patient's symptoms were improved. He was followed-up radiologically for brain lesion. Seven months after diagnosis he complained of back pain and gait disturbance. A brain MRI showed a newly-developed lesion at the left cerebellopontine angle without an interval change in the primary lesion. A spinal MRI demonstrated leptomeningeal dissemination of the entire spine. Radiation therapy (3750 cGy) to the spine, and adjuvant chemotherapy with a carboplatin plus vincristine regimen were administered. However, he had a progressive course with tumoral hemorrhage and expired 13 months after diagnosis. We report an unusual case of a low-grade brainstem glioma with spinal dissemination, but without local recurrence, and a progressive course associated with hemorrhage.

Extended follow-up of Hodgkin lymphoma (HL) survivors indicates that these patients are at high risk of secondary malignant neoplasms (SMNs) contributing to increased morbidity and mortality. This study examined the characteristics of HL survivors who developed SMNs with the aim to report any correlation with radiotherapy (RT) dose. In this retrospective multi-center cohort study of HL patients treated between 1990 and 2011 at three major teaching hospitals in Lebanon, classification was into two groups including those treated with combined modality (RT and chemotherapy-CHT) and those treated with CHT alone. Approval from the University Institutional Review Board (IRB) was obtained. Of the 112 patients evaluated, 52.7% (59) received the combined modality while 47.3% (53) received CHT alone. There were 6 cases of SMNs in the combined modality cohort and 5 cases in the CHT cohort. The mean RT dose in the combined modality cohort was 34.5 Gray (Gy) ($SD{\pm}5.3$). A statistically significant increase (1.5 fold) in the risk of developing SMNs was observed among patients who received a dose higher than 41 Gy compared to a dose between 20 to 30 Gy (OR= 1.5; 95% confidence interval= 0.674 to 3.339, p=0.012). The risk of SMNs was not significantly higher among patients who received extended field compared to involved field RT (p=0.964). This study showed that the risk of developing SMNs is higher among patients treated with RT dose greater than 31 Gy, independent of the RT type used.

Objectives: The purpose of this study is to investigate the various postpartum symptoms and the relevant factors. So it can provide fundamental data about postpartum health care. In conclusion, we can prevent and manage the postpartum disease by using this data. Methods: The subject of the present study was 94 women (63 women who completed vaginal delivery and 31 women who delivered by cesarean section) who completed labor between November 1, 2013 and January 31, 2016, at the clinic of OB&GYN. They have been taking good care of their health at postpartum clinic in Andong Woori Women Hospital. We investigated the various symptoms and situation which occurred from the moment of hospital to postnatal admission health care period, and Korean medical doctor examined the patients through the four examination methods. We classified the symptoms by maternal age, the frequency of maternal childbirth, the method of delivery, the delivery season, the term of pregnancy, the body weight of infant, the weight change of mother and the way of feeding. Results: There were no remarkable corelation in the frequency of symptoms according to maternal age, the way of delivery, the delivery season, the change of weight before and after of delivery, gestational weeks at delivery, the manner of feeding and the body weight of infants except for the frequency of maternal childbirth. Conclusion: The symptoms of hemorrhoids, the feeling of coldness and chilliness increased with increasing the frequency of maternal childbirth. Other circumstances, there was no relationship with symptoms of postpartum.
