Study Design: A retrospective, matched cohort study of a prospective database.Purpose: To evaluate the efficacy and safety of the Cervision system (Spinologics, Montreal, Canada), a new shoulder traction device that improves the fluoroscopic visualization of the lower cervical spine using caudal traction of the shoulders out of the radiographic field.Overview of Literature: Operating at a wrong level is a common error that may be committed by nearly 50% of surgeons during their career. Intraoperative fluoroscopy of the cervical vertebrae is an extremely important step in cervical spine surgery. Optimal lateral cervical radiography of the C1–T1 vertebrae is not always possible due to overlap of the shoulders.Methods: In this study, a group of patients (n=33, device group) underwent surgery with the new device used to apply caudal traction to both shoulders, and another group of patients (n=33, matched control group) had surgery with the tape traction. Data about the lowest vertebra visible on lateral fluoroscopic view, installation time, skin irritation under the traction area, and postoperative brachial palsy were recorded, and these parameters were analyzed using the <i>t</i>-test.Results: The mean numbers of visible cervical vertebra were 6.3±0.41 in the device group and 5.6±0.32 in the matched control group (<i>p</i> <0.01, unpaired <i>t</i>-test). The mean installation times were 83.9±5.15 minutes in the device group and 73.7±6.32 minutes in the matched control group (<i>p</i> <0.02). Seven patients from the matched control group presented with skin irritation. However, none of the patients from the device group had the condition (p =0.005, Pearson chi-square test). Postoperative brachial palsy was not observed in both groups.Conclusions: The Cervision system is more effective and superior to tape traction in pulling the shoulders down to improve the visualization of the cervical vertebra on lateral fluoroscopic view during cervical spine surgery.

In this comparative study with a control group of prisoners, psychiatric morbidity was measured in two groups of sentenced prisoners, each group completing the GHQ-30 and 21-item Beck Depression Inventory (BDI). Group 1 consisted of 40 segregated HIV-positive prisoners and group 2 a matched control group in the main prison who had no history of HIV seropositivity. All members of group 1 had a history of intravenous drug abuse. The mean GHQ-30 and BDI scores were significantly higher in group 1, and 90% of group 1 were psychiatric ‘cases’ compared with just over 42% of group 2. Levels of psychiatric morbidity present in a third group, consisting of HIV-positive prisoners who had not been segregated (prison authorities were unaware of their seropositivity) are an interesting pointer for further research.

1 The relationship between plasma chlorpropamide concentration and thyroid function was examined in 87 maturity onset diabetic patients receiving chronic therapy. 2 Although plasma chlorpropamide concentration was weakly negatively correlated with serum thyroxine (r= 0.33, P< 0.01) the mean serum thyroxine and thyrotrophin (TSH) were not different from that of a matched control group of diabetics treated with diet alone. 3 Serum thyroxine was negatively correlated with the duration of diabetes in both groups. 4 These results suggest that chlorpropamide does not have a clinically significant antithyroid effect.

In several previous studies it has been shown that the mean tremor amplitude displayed by morbidly anxious patients is greater than that of normal control subjects. The most detailed experiments were those carried out by Redfearn (1957). He compared the findings obtained in groups of male morbidly anxious patients and controls, and in addition to confirming the existence of a difference in tremor amplitude, he reported that the tremor of male anxious patients showed a greater degree of accentuation of the 8–10 c/sec. components than the tremor of a matched control group. Halliday and Redfearn (1956) compared the tremor spectra obtained from normal male and female subjects, and found that the curve for men was similar to that for women.

Abstract Introduction Handball is a contact sport which involves throwing and jumping, exposing players to serious physical stress. There is a high risk of injuries leading to possible long-term sequelae. The aim of this study was to assess the incidence of musculoskeletal injuries in elite male handball players compared with an age-matched control group. Patients and methods Former elite handball players, who had played on the Swiss national team between 1980 and 1985, answered a questionnaire about injuries, surgical interventions and their current health status. A total of 34 athletes were compared with 58 age-matched volunteers, who only engaged in recreational sports or no sports at all. Results The mean age of the athletes was 58.4 years (range 52–68 years) and did not differ significantly from the mean age of the control group of 58.7 years (range 53–69 years). In the control group, 70 % engaged in recreational sports. There was no statistical difference regarding the life-long incidence of shoulder injuries and surgical interventions, sequelae or persistent shoulder pain. Athletes had more interventions after elbow injuries (0.09 vs. 0, p = 0.047), but the difference with respect to chronic pain or late sequelae was not statistically significant. For knee injuries, there were no significant differences regarding the incidence of injuries or interventions, the prevalence of secondary consequences or persistent pain. Concerning the foot and ankle, there was a significantly higher incidence of injuries (0.5 vs. 0.03, p < 0.001) and interventions (0.5 vs. 0.09, p < 0.001) in athletes, but no statistical difference regarding sequelae or persistent pain. Overall quality of life had identical ratings in both groups (athletes mean 85.9 %, controls mean 85.8 %). Discussion Top handball players did not sustain more shoulder or knee injuries than the age-matched control group. The elbow was more at risk in these top athletes, but long-term consequences appeared to be less severe. The most distinctive difference was seen in foot and ankle injuries. Conclusions A career as an elite handball player had no adverse effect on the overall quality of life of elite handball players 25 to 30 years after retiring from professional sports.

At the Dr. Sami Ulus Children's Hospital Ankara, Turkiye, 20 patients, twelve being between 6 months-2 year old and eight being between 2-4 years, with their first febrile convulsions (FC) were examined for serum IgG, IgA, IgM levels during the period of March 1989-]uly 1989. Twenty healthy children were used as controls, seven being between 6 months-2 years old and thirteen being between 2-6 years. The serum IgG, IgA and IgM levels of the patients between 6 months-2 years were 805.000 + 307.8984 mg/ dl, 49.7167 + 27.9807 mg/dl and i55.1833 + 62.9696 mg/dl respecttvelly. The serum IgG, IgA and IgM levels of the patients between 2-4 years were : 989.1250 ± 314.5359 mg/dl, 92.6125 ± 34.5663 mg/dl and 159.8750 ± 45.6647 mg.ldl respectivelly. The mean IgA levels of the 12 FC patients between 6 months-2years were 49.7167 ± 27.9807 mg/dl and the mean level of IgA in the age matched control group was 81.0427± 31.3551 mg/dl and the difference between them was statistically significant (p <0. 005). We conclude that FC under 2 years of age is associated with low serum IgA levels.

Abstract In recognition of the GSA’s 75th Anniversary “Why Age Matters” we celebrate the 7th anniversary of the Gerofit dissemination initiative. Gerofit is an exercise and health promotion program for older Veterans that has been declared a Veterans Health Administration (VA) “Best Practice” and been disseminated to 17 VA’s across the country. Over 7000 Veterans have participated in Gerofit initiated programs and have reported robust outcomes including improved quality of life, physical and mental health, and high levels of satisfaction with the programs. For this symposium, we focus on newly acquired program outcomes that emphasize the importance of fitness as we age. The first paper compares hospitalization and emergency room visits between individuals participating in Gerofit for 12 months compared to a matched control group. The second paper describes four-year trajectories of physical performance to highlight the impact of becoming fit over expected normative trajectories. The third paper examines outcomes of a home-based geriatric walking clinic. The fourth paper describes the impact of exercise adherence on chronic pain. The fifth paper describes changes in medication utilization compared to a matched control group following 12-months of supervised exercise. These papers highlight the importance of fitness as a contributor to overall health during the aging process and celebrates that fitness matters, no matter when you start!

Group Survival

PURPOSE Recent studies indicate that BRCA1 breast and ovarian tumors may have an advantageous survival. In this population-based study, the survival of carriers of a mutated BRCA1 gene was investigated. PATIENTS AND METHODS The survival of 71 BRCA1-associated cancer patients (33 breast cancer, seven breast and ovarian cancer, and 31 ovarian cancer patients from 21 families with BRCA1 germline mutations) diagnosed after 1958 was compared with that of a population-based comparison group that consisted of all other invasive breast (n = 28,281) and ovarian (n = 7,011) cancers diagnosed during 1958 to 1995, as well as an age- and stage-matched control group. RESULTS No apparent survival advantage was found for BRCA1-associated breast cancers upon direct comparison. After adjustment for age and calendar year of diagnosis, survival was equal to or worse than that of the comparison group (hazards ratio [HR], 1.5; 95% confidence interval [CI], 0.9 to 2.4). In comparison with an age- and stage-matched control group, survival again appeared equal or worse (HR, 1.5; 95% CI, 0.6 to 3.7). For BRCA1-associated ovarian cancers, an initial survival advantage was noted that disappeared with time. Due to this time dependency, multivariate analyses cannot adequately be analyzed. Compared with the age- and stage-matched control group, survival again appeared equal or worse (HR, 1.2; 95% CI, 0.5 to 2.8). CONCLUSION The results suggest that survival for carriers of a BRCA1 mutation may be similar, or worse than, that for breast and ovarian cancer in general. This finding is in accordance with the adverse histopathologic features observed in BRCA1 tumors and underlines the need for surveillance in families that carry a BRCA1 mutation.

We investigated the effects of nutrient intake timing on glycogen accumulation and its related signals in skeletal muscle after an exercise that did not induce large glycogen depletion. Male ICR mice ran on a treadmill at 25 m/min for 60 min under a fed condition. Mice were orally administered a solution containing 1.2 mg/g carbohydrate and 0.4 mg/g protein or water either immediately (early nutrient, EN) or 180 min (late nutrient, LN) after the exercise. Tissues were harvested at 30 min after the oral administration. No significant difference in blood glucose or plasma insulin concentrations was found between the EN and LN groups. The plantaris muscle glycogen concentration was significantly (p < 0.05) higher in the EN group—but not in the LN group—compared to the respective time-matched control group. Akt Ser473 phosphorylation was significantly higher in the EN group than in the time-matched control group (p < 0.01), while LN had no effect. Positive main effects of time were found for the phosphorylations in Akt substrate of 160 kDa (AS160) Thr642 (p < 0.05), 5'-AMP-activated protein kinase (AMPK) Thr172 (p < 0.01), and acetyl-CoA carboxylase Ser79 (p < 0.01); however, no effect of nutrient intake was found for these. We showed that delayed nutrient intake could not increase muscle glycogen after endurance exercise which did not induce large glycogen depletion. The results also suggest that post-exercise muscle glycogen accumulation after nutrient intake might be partly influenced by Akt activation. Meanwhile, increased AS160 and AMPK activation by post-exercise fasting might not lead to glycogen accumulation.

SynopsisIn 17 benzodiazepine (BDZ) dependent in-patients a CT scan was performed before initiation of withdrawal therapy. The evaluation of the ventricular to brain ratio (VBR) by standardized and computerized measurements revealed significantly higher mean VBRs for both high-and low-dose BDZ-dependent patients compared to the mean VBR of an age- and sex-matched control group. In addition, the mean VBR of high-dose BDZ-dependent patients (N = 8) was significantly higher than the mean VBR of low-dose BDZ-dependent patients (N = 9). This difference could not be accounted for by the age of the patients or duration of BDZ-dependency and, therefore, suggests a dose-dependent effect of BDZs on the enlargement of internal CSF-spaces. On the other hand, higher values for the width of external CSF-spaces were found to be related to increasing age of the patients and duration of BDZ-dependency.
