Effect of Weight Change on Markers of Bone Turnover and Phosphorus Excretion.

There is little information about how weight change in horses impacts bone turnover and the metabolism of minerals associated with bone. This study evaluated weight change in mature horses as a factor that could alter bone turnover and fecal P output. Fifteen horses (555 ± 8 kg) were assigned to three treatments: weight loss (LO; n = 5), weight maintenance (MA; n = 5), and weight gain (GA; n = 5). Diets contained 75%, 100%, and 145% of maintenance digestible energy requirements for the three treatments, respectively, but contained similar amounts of protein and minerals. At the end of the weight change period (27 ± 6 d), blood samples were analyzed for bone biomarkers and a 5-day total fecal collection was conducted to measure fecal mineral output. Horses fed the MA diet had an average daily weight change that was not different from either the GA or LO treatments, while weight change was different between the GA group and the LO group (0.49 kg/d vs. -1.16 kg/d; P = .017). Weight change was negatively correlated with cross-linking C-terminal telopeptides of type-I collagen, a biomarker of bone resorption (r = -0.62; P = .014) and tended to be positively correlated with bone alkaline phosphatase, a biomarker of bone formation (r = 0.48; P = .068). Also, fecal P output tended to be lower in GA than in LO horses (P = .085), while MA was intermediate and not different, suggesting that weight loss was increasing bone resorption, resulting in a tendency for higher P loss from the body. Weight change in horses can influence bone metabolism as well as mineral excretion.

[The Body Dysmorphic Disorder in Plastic Surgery - A Systematic Review of Screening Methods]. / Die körperdysmorphe Störung in der Plastischen Chirurgie ­ Eine systematische Übersicht der Screening-Methoden.

BACKGROUND: The body dysmorphic disorder (BDD) is considered to be a sub-form of somatoform disorders. BDD can express itself in a delirious experience, an excessive evaluation and employment of the external appearance, in particular the face. Preliminary results suggest that individuals with BDD do not benefit from plastic surgery, so that aesthetic surgery often results in aggravation of their symptoms. Thus, the identification of signs for a BDD is crucial, whether a patient should be operated plastically-aesthetically. This overview explains the often difficult diagnostics of the BDD by summarizing the current literature on its screening. STUDY DESIGN: Systematic overview METHODS: An electronic search was conducted in the German and English-language literature in order to identify all screening instruments for the BDD. The specific development RESULTS: Six different screening instruments were identified for the BDD. Only two of these were evaluated in a cosmetic setting: the "Body Dysmorphic Disorder Questionnaire Dermatology Version" (BDDQ-DV) and the "Dysmorphic Concern Questionnaire" (DCQ). The influence on the subjective results after a plastic-aesthetic procedure was measured only for the DCQ. CONCLUSION: The limited availability of validated screening instruments for BDD in plastic surgery is markedly in contrast to the supposedly high prevalence of the disease of 2.4 %. Among the currently used screening tools, the BDDQ-DV and the DCQ appear to be most suitable. Further research efforts are needed to establish better screening methods for the BDD in the plastic surgical patient population and to examine the effects of BDD on treatment results.

The Role of Current Techniques and Concepts in Peripheral Nerve Repair.

Patients with peripheral nerve injuries, especially severe injury, often face poor nerve regeneration and incomplete functional recovery, even after surgical nerve repair. This review summarizes treatment options of peripheral nerve injuries with current techniques and concepts and reviews developments in research and clinical application of these therapies.

Utilização de contrairritante no tratamento da fixação dorsal de patela intermitente em equinos: relato de casos / The use of counterirritant in the treatment of upward fixation of intermittent patella in horses: case report

Em nove equinos atendidos por apresentarem fixação dorsal de patela intermitente, optou-se pela aplicação de 2mL de contrairritante na região subcutânea, ao longo dos ligamentos patelares medial e intermédio. No período de 12 a 48h após a aplicação, os animais apresentaram aumento de volume e de temperatura local, sensibilidade dolorosa à palpação e relutância à locomoção. Após esse período, os sinais clínicos de inflamação e fixação dorsal de patela foram gradativamente diminuindo até o sétimo dia, em sete dos nove animais avaliados. Após a remissão dos sinais de inflamação, dois animais não responderam ao tratamento, sendo necessária a repetição em um dos casos e realização de desmotomia patelar medial no outro. A aplicação de contrairritante foi eficaz na remissão do sinal clínico de fixação dorsal da patela intermitente. Comparativamente às técnicas cirúrgicas para a correção da enfermidade descritas na literatura, o tratamento promoveu melhora precoce dos sinais, curto período de convalescência e praticidade na realização.

Nine horses were admitted showing intermittent lameness due to upward fixation of the patella (UFP) and were injected with 2mL of counter-irritant subcutaneously, through the middle and medial patellar ligaments. From 12 to 48 hours after application, these animals showed increased volume and local temperature, painful response to palpation and reluctance to bear weight. Subsequently, the inflammatory signs were gradually decreasing until the seventh day, along with signs of UFP in seven of the nine animals. After remission of inflammatory signs, two of the nine horses did not respond to the treatment. In these two animals, one horse needed a repeated counter-irritant injection and the other received the medial patellar desmotomy. The use of counter-irritant was effective in the remission of clinical signs of UFP. In comparison with the surgical techniques described in literature used to correct this disease, the proposed treatment promoted early improvement of clinical signs, short term recovery and was easily performed.

Smoke-free legislation and charitable gaming in Kentucky.

OBJECTIVE: To determine the effect of municipal smoke-free laws in Kentucky on gross and/or net revenues from charitable gaming activities. Between January 2000 and June 2007, 13 Kentucky communities implemented smoke-free legislation; only three specifically exempted charitable gaming facilities and compliance in several communities was not consistent. Kentucky is a tobacco-growing state that has the highest smoking rate in the United States. DESIGN: A fixed-effects time series design to estimate the impact of municipal smoke-free laws on charitable gaming. SETTING: 13 Kentucky counties that implemented smoke-free laws during the study period of January 2000 through June 2007. SUBJECTS: All charitable gaming facilities in 13 counties in which a smoke-free ordinance was enacted during the study period. MAIN OUTCOME MEASURES: Gross and net revenues from charitable gaming activities in each county for each quarter of the study period, obtained from the Kentucky Department of Charitable Gaming. RESULTS: When controlling for economic variables, county-specific effects and time trends using a robust statistical framework, there was no significant relation between smoke-free laws and charitable gaming revenues. Municipal smoke-free legislation had no effect on charitable gaming revenues. CONCLUSIONS: No significant harm to charitable gaming revenues was associated with the smoke-free legislation during the 7.5-year study period, despite the fact that Kentucky is a tobacco-producing state with higher-than-average smoking rates.

The stability of health status measurement (SF-36) in a working population.

This study tests the stability of health status measurement (SF-36) in a working population. A total of 4,225 employees from two sectors (one state agency, one private company) enrolled in three health plans at Trigon BlueCross/BlueShield of Virginia. An eight-dimension short-form health survey (SF-36) was first tested on a cross-sectional basis for its validity. Then, a panel study was established to test for the stability of health status instrument over time. Structural equation modeling built on equality constraint conditions was the statistical technique for this study. Data were collected through two-wave mail surveys. Both comprehensive (original eight scales) and parsimonious (revised five scales) models of health status were found fit into the data quite well. Furthermore, the revised parsimonious model was shown highly stable over time. Within a working population aged 18 to 64, people are relatively healthy. Their perception of health issues is reflected mainly on "physical health status," as indicated by physical functionings or role limitations. The high stability of revised health status model warrants the possibility of using a more concise health status instrument for the majority of people in working force.

Evaluation of the total cost of treating elderly hypertensive patients with ACE inhibitors: a comparison of older and newer agents.

We compared total costs and adherence to the regimen of older versus newer angiotensin-converting enzyme (ACE) inhibitors for the treatment of elderly patients with hypertension. A computer search using the data base of a health care insurer identified 6176 subjects age 65 years or older who had ICD-9 coding for hypertension only and had a new prescription for an ACE inhibitor dispensed between April 1, 1992, and January 31, 1993. Subjects receiving concurrent antihypertensive drugs were included. Total cost of therapy included acquisition costs for the ACE inhibitors and concurrent antihypertensive agents, and nondrug costs. Other costs were laboratory tests, hospitalization, and clinic visits associated with monitoring outcomes of antihypertensive therapy. Total median cost per month was greater for older than for newer agents, $59.82 versus $53.09 (p<0.0009). The mean percentage of patients complying with therapy as determined by refill data was greater with newer than with older agents, 66% versus 58% (p<0.0001). Based on our results, newer ACE inhibitors should be first-line antihypertensive therapy in elderly patients. They also should be considered for elderly patients who are unresponsive to older ACE inhibitors.
