Handgrip strength predicts pressure ulcers in patients with hip fractures

Objective: Pressure ulcer (PU) is a frequent complication of hip fracture. Studies were carried out to identify the risk factors of PU development after hip fractures. The objective of the study was to determine the role of anthropometric measurements and handgrip strength as predictors of PUs in patients with hip fractures during their hospital stay and 30 d after discharge, which has not yet been established.Methods: Ninety-two consecutive patients with hip fractures who were older than 65 y old and admitted to an orthopedic unit were prospectively evaluated. Within the first 72 h of admission, each patient's characteristics were recorded, anthropometric measurements were taken (circumferences of the arm, waist, thigh, calf, triceps, and biceps and subscapular and suprailiac skinfolds), handgrip strength was measured, and blood samples were collected. PU evaluations were performed during the hospital stay and 30 d after hospital discharge.Results: Three patients were excluded because of PUs before hospitalization. Eighty-nine patients (average age 80.6 +/- 7.5 y) were studied; 70.8% were women, and 49.4% developed PUs during their hospital stay. In a univariate analysis, length of hospital stay (P = 0.001) and handgrip strength (P = 0.02), but not body circumferences and skinfolds, were associated with PUs during a hospital stay. Only handgrip strength (P = 0.007) was associated with PUs 30 d after hospital discharge. In a multivariate analysis, only handgrip strength was found to predict PU development at these points.Conclusion: Handgrip strength was found to predict PU development in patients with hip fractures during their hospital stay and 30 d after discharge.

Avaliação radiográfica de cães com displasia coxofemoral tratados pela sinfisiodese púbica

Avaliou-se a progressão dos sinais radiográficos de cães com displasia coxofemoral ou potencialmente displásicos tratados pela técnica da sinfisiodese púbica. Foram utilizados 14 cães, seis machos e oito fêmeas, com idades entre quatro e seis meses. Após exame físico, procedeu-se ao exame radiográfico para avaliação da articulação coxofemoral, segundo padrão estabelecido pelo Colégio Brasileiro de Radiologia Veterinária. Três deles foram também avaliados pelo método PennHIP. Pelo histórico clínico, nove (64%) animais foram trazidos por manifestarem sinais de dificuldade locomotora com os membros pélvicos, manifestada especialmente por claudicação unilateral ou bilateral e dificuldade de se levantar. Cinco (36%) cães não tinham qualquer sinal clínico, e em quatro (29%) realizou-se o exame radiográfico como prevenção. O sinal físico mais evidente foi dor à palpação da articulação coxofemoral, e dois (14%) cães apresentaram sinal de Ortolani positivo. Com exceção de um cão que apresentou infecção nos pontos cutâneos, todos os demais evoluíram sem complicações no período pós-operatório. Radiograficamente houve progressão das lesões articulares em seis (43%) animais e oito (57%) mantiveram a classificação inicial. Concluiu-se que cães tratados pela sinfisiodese púbica não apresentam melhora dos sinais radiográficos iniciais.

Acetabular deepening in the treatment of severe canine hip dysplasia

Uma técnica para restituir a anatomia acetabular com aprofundamento da cavidade acetabular e reconstrução do ligamento da cabeça do fêmur e da cápsula articular, foi testada em nove cães, de raças de grande porte, portadores de displasia coxofemoral grave com subluxação acentuada ou luxação. O procedimento cirúrgico foi constituído de duas fases. Inicialmente, foi realizada a pectineotomia bilateral em todos os cães. A segunda intervenção nos mesmos cães incluiu abordagem e aprofundamento do acetábulo, reconstrução do ligamento da cabeça do fêmur e da cápsula. em geral, 30 dias após a cirurgia, os cães apoiavam o membro operado para se locomover. Com exceção de dois cães, todos os outros recuperaram a função locomotora do membro pélvico dentro de 60-90 dias. É concluído que a técnica de acetabuloplastia é uma boa alternativa para o tratamento da displasia coxofemoral grave.

Maxillo-mandibular counter-clockwise rotation and mandibular advancement with TMJ Concepts (R) total joint prostheses Part III - Pain and dysfunction outcomes

47 end-stage TMJ patients with high occlusal plane angulation, treated with TMJ custom-fitted total joint prostheses and simultaneous maxillo-mandibular counter-clockwise rotation were evaluated for pain and dysfunction presurgery (T1) and at the longest follow-up (T2). Patients subjectively rated their facial pain/headache, TMJ pain, jaw function, diet and disability. Objective functional changes were determined by measuring maximum interincisal opening (MIO) and laterotrusive movements. Patients were divided according to the number of previous failed TMJ surgeries: Group 1 (0-1), Group 2 (2 or more). Significant subjective pain and dysfunction improvements (37-52%) were observed (<0.001). MIO increased 14% but lateral excursion decreased 60%. The groups presented similar absolute changes, but Group 2 showed more dysfunction at T1 and T2. For patients who did not receive fat grafts around the prostheses and had previous failure of proplast/teflon and or silastic TMJ implants, more than half required surgery for TMJ debridement and removal of foreign body giant cell reaction and heterotopic bone formation. End-stage TMJ patients can be treated in one operation with TMJ custom-made total joint prostheses and maxillo-mandibular counter-clockwise rotation, for correction of dentofacial deformity and improvement in pain and TMJ dysfunction; Group 1 patients had better results than Group 2 patients.

Medical conditions and body pain in patients presenting orofacial pain

OBJETIVO: Verificar a frequência de problemas médicos autorrelatados e a frequência de áreas de dor no corpo em pacientes com dor orofacial, comparando-os a pacientes submetidos a tratamento odontológico de rotina. MÉTODOS: Os dados foram coletados dos arquivos da Clínica de Dor Orofacial (Grupo A, n=319) e de clínicas de tratamento odontológico rotineiro (Grupo B, n=84) da Faculdade de Odontologia de Araraquara, São Paulo, Brasil. Os indivíduos responderam a questionários e preencheram um mapa corporal indicando os locais de dor. RESULTADOS: O teste de Mann-Whitney demonstrou que o Grupo A apresentou uma média de relatos de problemas médicos superior ao Grupo B (p=0,004). Para ambos os grupos, o teste de correlação de Pearson demonstrou correlação positiva entre os problemas médicos e a frequência de áreas dolorosas (respectivamente, 0,478, p=0,001 e 0,246, p=0,000). CONCLUSÕES: O Grupo A relatou maior número de problemas médicos e houve correlação positiva entre a frequência desses problemas e a de áreas de dor para ambos os grupos.

Carprofen and buprenorphine prevent hyperalgesia in a model of inflammatory pain in cats

A model of nociceptive threshold determination was developed for evaluation of NSAID analgesia in cats. In a crossover study, eight cats received carprofen (4 mg/kg), buprenorphine (0.01 mg/kg) or saline (0.3 ml) subcutaneously before intradermal kaolin injection on the antebrachium to induce mild inflammation. Pressure thresholds were measured at the injected site using blunt-ended pins advanced by manual inflation of a bladder within a bracelet. Bladder pressure was recorded as threshold (PT) at the behavioural end point. Baseline PT were recorded before kaolin injection (time 0). PT was measured at 2-10 h intervals for 52 h. PT below the lower 95% confidence interval (CI) of baseline values indicated hyperalgesia. After saline, hyperalgesia was detected from 2-6 h, 22-26 h, and at 30 and 36 h. After carprofen, PT remained within the 95% CI. After buprenorphine, PT remained within the 95% CI except at 2 h. Carprofen and to some extent buprenorphine, prevented inflammatory hyperalgesia.

Thermography and ultrasonography in back pain diagnosis of equine athletes

The object of the current study was to evaluate the efficacy of thermography and ultrasonography in the diagnosis of thoracolumbar lesions in Quarter Horse athletes and associate the different types of lesions found with the athletic modality practiced. Twenty-four horses were admitted to the Surgery Service for Large Animals of the Veterinary and Animal Science Faculty, UNESP, Botucatu, Brazil, with complaints of back problems. All the horses were submitted for physical examinations to confirm the existence of thoracolumbar alterations and then for thermography and ultrasonography Thermography was used to map the lesioned areas of this region and ultrasonography for lesion characterization. The lesions found were supraspinous desmitis, interspinous desmitis, dorsal intervertebral osteoarthritis, and impingement of the spinous processes or kissing spines. The existence of a relation between the type of event practiced by the horse and the type of lesion found was determined. In horses that competed in the barrel race, a predominance of lesions in the thoracic caudal, thoracolumbar, and cranial lumbar regions occurred, with intervertebral osteoarthritis and interspinous desmitis being the most common. In cutting horses, most of the lesions were observed in the caudal lumbar region, whereas horses competing in reining showed a preferential location for lesions in the middle lumbar, with a predominance of supraspinous desmitis and myositis. Thermography associated with ultrasonography was shown to be efficient in the diagnosis of the thoracolumbar lesions of these horses.
