BACKGROUND: The duration of immobilization after arthroscopic rotator cuff repair and the optimal time to commence rehabilitation are still the subject of ongoing debates. This study was undertaken to evaluate the functional outcome and rotator cuff healing status after arthroscopic rotator cuff repair by comparing early and delayed rehabilitation. METHODS: Totally, 76 patients with small, medium, and large sized rotator cuff tears underwent arthroscopic repair using the suture-bridge technique. In early rehabilitation group, 38 patients commenced passive range of motion at postoperative day 2 whereas 38 patients assigned to the delayed rehabilitation group commenced passive range of motion at postoperative week 3. At the end of the study period, clinical and functional evaluations (Constant score, the University of California, Los Angeles [UCLA] shoulder score) were carried out, subsequent to measuring the range of motion, visual analogue scale for pain, and isokinetic dynamometer test. Rotator cuff healing was confirmed by magnetic resonance imaging at least 6 months after surgery. RESULTS: No significant difference was obtained in range of motion and visual analogue scale between both groups. Functional outcomes showed similar improvements in the Constant score (early: 67.0–88.0; delayed: 66.9–91.0; p<0.001) and the UCLA shoulder score (early: 20.3–32.3; delayed: 20.4–32.4; p<0.001). Furthermore, rotator cuff healing showed no significant differences between the groups (range, 6–15 months; average, 10.4 months). CONCLUSIONS Delayed passive rehabilitation does not bring about superior outcomes. Therefore, early rehabilitation would be useful to help patients resume their daily lives.

Worldwide, caffeine is among the most commonly used stimulatory substances. Unfortunately, significant caffeine consumption is associated with several adverse effects, ranging from sleep disturbances (including insomnia) to cardiovascular problems. This study investigates whether treatment with the Evodia rutaecarpa aqueous extract (ERAE) from berries and its major molecular component, evodiamine, can reduce the adverse caffeine-induced sleep-related and excitation effects. We combined measurements from the pentobarbital-induced sleep test, the open field test, and the locomotor activity test in mice that had been dosed with caffeine. We found that ERAE and evodiamine administration reduced the degree of caffeine-induced sleep disruption during the sleep test. Additionally, we found that evodiamine significantly inhibits caffeine-induced excitation during the open field test, as well as decreasing hyperlocomotion in the locomotor activity test. Additional in vitro experiments showed that caffeine administration decreased the expression of γ-aminobutyric acid (GABA)(A) receptor subunits in the mouse hypothalamus. However, evodiamine treatment significantly reversed this expression reduction. Taken together, our results demonstrate that ERAE and its major compound, evodiamine, provide an excellent candidate for the treatment or prevention of caffeine-induced sleep disturbances and excitatory states, and that the mechanism of these beneficial effects acts, at least in part, through the GABA(A)-ergic system.

BACKGROUND: In a gynecologic cone biopsy, fentanyl is commonly used with propofol for its analgesic effect, but it has many side effects, such as bradycardia, respiratory depression and hypotension. A subanesthetic dose of ketamine has an analgesic effect and minimal cardiovascular effects. We wanted to know whether ketamine can be safely used with propofol in a gynecologic cone biopsy instead of fentanyl. METHODS: Forty woman patients were randomly allocated to two groups. All patients were anesthesized with a propofol infusion. Fentanyl 1mug/kg IV was injected 2 minutes before LMA (laryngeal mask airway) insertion in group I, ketamine 0.25 mg/kg IV was injected also in group II. Blood pressure and heart rate were measured before fentanyl or ketamine injection, 1 minute, 3 minutes and 5 minutes after LMA insertion, and during the operation. A numerical rating scale (NRS) for pain and other side effects were checked for 24 hours after the operation. RESULTS: There were no significant differences between the two groups in blood pressure, heart rate, NRS and side effects, but a more stable systolic blood pressure in the ketamine group occured. CONCLUSIONS: For a gynecologic cone biopsy, propofol anesthesia combined with fentanyl or ketamine was not different for stable cardiovascular results, postoperative pain relief and side effects. Therefore, ketamine as an analgesic combined with propofol could replace fentanyl in gynecologic cone biopsy anesthesia.

BACKGROUND: Human papillomavirus (HPV) infection is the main cause of cervical cancer and with the advent of genotype specific vaccines, there is increased need for accurate, broad-spectrum and high-throughput methods for HPV genotyping. A MALDI-TOF mass spectrometry (MS)-based restriction fragment mass polymorphism (RFMP) assay has proven to accurately and reliably genotype a wide variety of HPV. METHODS: We evaluated the clinical utility of the RFMP assay in HPV genotyping by testing a total of 2,689 specimens taken from liquid-based cytology, which was composed of normal cytology, atypical squamous cells of undetermined significance (ASCUS), low grade squamous intraepithelial lesion (LSIL), high grade squamous intraepithelial lesion (HSIL) and invasive squamous cervical cancer (SCC). RESULTS: Overall HPV positive rate of total specimens was 32.5% and the high-risk positivity was 16.4%. The HPV positive rates were increased as increasing severity level of cervical lesion. Predominant high-risk HPV genotypes were found as following order; 52 (18.6%), 16 (13.7%), 18 (3.8%), 58 (3.4%), 56 (2.6%) and 31 (2.5%). The high-risk HPV positivities according to cytologic diagnosis were 10.7% (238/2229), 31.7% (76/240), 50.0% (88/176), 86.0% (37/43), 100% (1/1) in normal, ASCUS, LSIL, HSIL and SCC subgroups, respectively. The concordance rate and Kappa value between sequencing and RFMP assays were 96.6% and 0.932 (95%CI: 0.908-0.956). CONCLUSIONS: The RFMP HPV genotyping assays showed high concordance with sequencing. The assay is simple, and can accurately detect and identify HPV genotypes in samples with various levels of cytological lesions. The results demonstrated that RFMP assay should be clinically suitable for HPV genotyping in laboratories.

Inflammatory bowel disease is associated with extraintestinal manifestations involving almost every organ system in the body. Crohn's disease (CD) appears to be more commonly associated with an inflammatory myopathy than ulcerative colitis. However, myopathy of the thigh in patients with CD is rare. We report an unusual site of necrotizing myositis in a patient with CD. A 23-year-old woman presented with swelling and pain at the left popliteal area that had lasted for 1 week. Twenty-two months before admission, she had presented with pyoderma gangrenosum on the left upper chest and was diagnosed with CD. A magnetic resonance imaging scan of her leg revealed diffuse swelling in the left semimembranous muscle and biceps femoris muscle that was compatible with myositis, and a cystic lesion in the distal portion of the semimembranous muscle. The findings from semimembranous muscle biopsy were also consistent with necrotizing myositis. In conclusion, myositis, although rare, can be an extraintestinal manifestation of CD.

OBJECTIVES: The current study investigated the risk of smartphone addiction among children and adolescents with or without attention-deficit hyperactivity disorder (ADHD), risk of depression, anxiety, and self-esteem using the Smartphone Addiction Scale Proneness, Kovac's Children's Depression Inventory, State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale, commonly used in clinical medicine. METHODS: Ninety five students with ADHD who visited psychiatry outpatient clinics completed the questionnaire. At the same time, 592 middle and high school students living in a similar area regardless of ADHD diagnosis, completed the questionnaire as control subjects. RESULTS: Overall, 40.0% of 95 ADHD and 12.8% of 592 control subjects were classified as the smartphone addiction proneness group, 26.3% of the ADHD subjects and 8.3% of the control group were classified as the depression group, and 32.6% of the ADHD subjects and 16.2% of the control group were classified as the anxiety group. Significant differences were observed between the two groups. CONCLUSION: The results of this study suggest that ADHD subjects are more prone to smartphone addiction, becoming depressed or anxious than those in the control group. From this study, we could suggest that students with ADHD are more easily affected by smartphone addiction than normal control subjects. In addition, we might understand how some psychiatric problems like depression, anxiety, and low self-esteem are related to ADHD and smartphone addiction.

BACKGROUND: Osteoporosis in men is an important public health problem. Because of the tendency of the numbers of the elderly population to increase, and age-specific incidence of fractures, it is inevitable that the health burden due to fractures will increase. Chronic alcoholism is associated with other risk factors, such as poor nutrition, leanness, liver disease, malabsorption, vitamin D deficiency, hypogonadism, hemosiderosis, parathyroid dysfunction and tobacco use, and these may contribute to the pathogenesis of bone disease related to alcoholism. Chronic alcohol intake may reduce bone density, but can also increase bone density. It is well established that liver disease also induces bone density changes, thus it is difficult to distinguish the role of liver disease from that of alcohol itself in the bone alterations occurring in patients with chronic alcohol consumption. Chronic male alcoholics, not having liver cirrhosis were studied to assess the effect of chronic alcohol consumption on their bone mineral density. METHODS: The study subjects comprised of 18 chronic heavy drinkers of more than 40 g of alcohol per day for at least 3 years and 18 age-matched controls who drank less than 20 g of alcohol per day. The serum and urinary parameters of bone and mineral metabolism were determined. The bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry at four axial sites (lumbar spine, femoral neck, Ward's triangle and trochanter). RESULTS: The alcoholic and control patients drank an average of 97.6 g and 7.2 g of alcohol per day. Osteocalcin, a marker of bone formation, was slightly decreased in alcoholic patients, and deoxypyridinoline, a marker of bone resorption, was slightly increased, but the difference was not statistically significant (p> 0.05). There were no differences between the two groups in the levels of free testosterone, estradiol, 25 (OH) vitamin D and parathyroid hormone. The Ward's triangle and trochanter BMDs of the femur were significantly lower in the alcoholics than the controls, and lumbar spine BMD was decreased in proportion to the total alcohol intake in the alcoholics (r=-0.625, p=0.01). CONCLUSION: We suggest that chronic alcohol consumption induces low bone density in the femur Ward's triangle and trochanter. There was also a significant inverse correlation between the lumbar spine BMD and the total amount of alcohol consumed. Large scaled randomized and prospective studies are needed to clarify the pathogenesis of alcohol-induced osteoporosis.

BACKGROUND: Currently, combined spinal-epidural anesthesia (CSE) is frequently administered, especially in obstetrics and orthopedic surgery. The aim of this study is to determine the appropriate concentration of bupivacaine to use with epidural volume extension that is suitable for total knee replacement during CSE. METHODS: Eighty patients (ASA physical status I and II) scheduled for totalknee replacement were randomly allocated to four groups of 20 patients each: All patients intrathecally received 2 ml of 0.5% hyperbaric bupivacaine. After fixation of spinal anesthesia, the groups received the following treatments. Group S patients received a 10 ml administration of normal saline for 15 min followed by a continuous 10 ml/hr epidural infusion. Group B1 patients received a 10 ml administration of 0.125% bupivacaine for 15 min followed by a continuous 10 ml/hr epidural infusion. Group B2 patients received a 10 ml administration of 0.25% bupivacaine for 15 min followed by a continuous 10 ml/hr epidural infusion. Group B3 patients received a 10 ml administration of 0.5% bupivacaine for 15 min followed by a continuous 10 ml/hr epidural infusion. RESULTS: The incidence of intraoperative movement in group S and group B1 patients were significantly greater than the incidence for group B2 and B3 patients. The incidence of intraoperative pain in group S patients was significantly greater than for patients in any of the other groups. CONCLUSIONS: We conclude that it is necessary to administer more than a 0.25% concentration of epidural bupivacaine load and provide continuous administration after a spinal block during total knee replacement.

BACKGROUND: Osteoporosis in men is an important public health problem. Because of the incremental tendency of elderly population and age-specific incidence of fracture, it is inevitable that the health burden of fracture will increase. Also, the mortality of fracture in men is higher than in women. Alcohol consumption is a risk factor for osteoporosis based on the frequent finding of a low bone mass decreased bone formation rate and increased fracture incidence in alcoholics. Chronic alcohol consumption may reduce bone density but also increase bone density. It has been well established that liver cirrhosis also induces bone density changes and thus it is difficult to distinguish the role of liver disease from that of alcohol itself in bone alterations occurring in patients with chronic alcohol consumption. So we studied male chronic alcoholics which did not have liver cirrhosis to assess the effect of chronic alcohol consumption on bone mineral density. METHODS: We studied 18 chronic heavy drinkers of more than 40 g/day for at least 5 years and age-matched 18 control groups who had drunk alcohol less than 20 g/day. Serum and urinary parameters of bone and mineral metabolism were determined. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry at four axial sites (lumbar spine, femoral neck, ward's triangle and trochanter). RESULTS: Alcoholic patients drank alcohol 97.7 g/day. Osteocalcin, a marker of bone formation, was slight decreased in alcoholic patients and deoxypyridinoline, a marker of bone resorption, was slight increased but not statistically significant (p > 0.05). The levels of 25-(OH)-vit D, parathyroid hormone, free testosterone, estradiol were not different between the two groups. Ward's triangle and trochanter BMD of femur were significantly lower than controls and L-spine BMD decreased parallel with total alcohol intake amount in the alcoholics (r=-0.62, p < 0.05). CONCLUSION: We suggest that chronic alcohol consumption induced low bone density on femur ward and trochanter. And there was significant inverse correlation between L-spine BMD and total alcohol consumption amount. The large scaled randomized and prospective studies are needed to clarify the pathogenesis of alcohol-induced male osteoporosis.
