Pseudotumor de pisiforme: a propósito de 1 caso

Se presenta 1 caso de pseudotumor del pisiforme con dolor crónico en eminencia hipotenar y compresión del nervio cubital en un varón de 33 años. El diagnóstico histológico definitivo fue de callo hipertrófico con degeneración cartilaginosa focal del hueso pisiforme. Se presupone el origen laboral de la lesión, secundaria a microtraumatismos repetidos por martillo neumático. Se practicó exéresis simple del hueso, con un resultado excelente a los 6 meses. Los autores piensan que el tratamiento de elección hubiera sido la inmovilización precoz al comienzo de la sintomatología.A case of pseudotumor of the pisiform vvith cronic pain in the hipothenar eminence and compression neuropathy of the ulnar nerve in Guyon's canal in a 33 year old man is reported. Pathologic diagnosis was consistent vvith hypertrophic fracture callus and focal degenerative changes in the articular surface of the pisiform. Repetitive minor trauma in his job as a miner, while using pneumatic hammer is presumed to be the main etiologic factor. Simple excision of the pisiform was performed vvith excelent functional result at 6 months. The authors believe that early inmobilization when the symptoms started, vvould have been the ideal treatmen

Body composition in breast cancer survivors in Sonorenses women

INTRODUCTION: Breast cancer is the most common type of cancer in the worldwide. In the same sense, this disease is one of the most common cancers affecting Mexican women. In the year 2014 in México, there were 11,372 new cases of breast cancer with an incidence rate of 22.56 per 100,000 in habitants older than 10 years. Women with breast cancer are often subjected to an operation due to this affectation which decreases its functionality and body composition. PURPOSE: To examine the body composition in breast cancer survivors in a sample of women from Hermosillo, Sonora, México. METHODS: This study was a cross-sectional descriptive study design. 21 women with breast cancer who had been operated on left arm and had been recruited at one university-based exercise program for breast cancer survivors in Hermosillo, Sonora, México. Body composition (BC) was measured. The right arm non-operated was considered as control. Statistical difference between the operated versus non-operated arm were determined with t-student test for independent samples. RESULTS: In the present study, body fat (1719.1 ± 456.7 vs. 1819.8 ± 467.9 grams, p ≤ 0.05), lean mass (1960.2 ± 308.7 vs. 2151.5 ± 313.5 grams, p ≤ 0.05) and total body mass (3679.3 ± 643.3 vs. 3971.1 ± 675.9 grams, p ≤ 0.05) of the left operated arm of women who breast cancer survivors were significantly lower than the mean of the right non-operated arm. CONCLUSION: Breast cancer survivors’ women who have underwent an operation on their left arm sowed a lower percentage of fat, fat mass and total mass compared to their non-operate arm. The present study underline the importance to apply rehabilitation or exercise program focused to reduce the changes in the body composition

VO2peak and Watt exercise testing: arm crank vs cycle ergometry

INTRODUCTION: Multiple sclerosis is a disease of the central nervous system that primarily affects the strength and functional capacity of the lower extremities. PURPOSE: The objectives of the present study were evaluate VO2peak and the power output (W) during a leg and an arm test performance in relapsing-remitting multiple sclerosis (MS) versus healthy people (HP). METHODS: Twelve women (age 45.8 ± 11.8 yr) with MS (EDSS 3.3 ± 1.8) and twelve women (age 45.6 ± 10.7 yr) HP were included in this study. They underwent two incremental exercise tests on an electromechanical braked arm crank ergometer and on an electromagnetic braked leg cycling ergometer separately. A computerized gas analysis system collected and analyzed gas exchange during the two kinds of testing. The statistical analysis was determined with the Wilcoxon test. RESULTS: First, VO2peak (21.5 ± 5.9 vs. 30.5 ± 4.8 ml·kg·min-1, p = 0.001) y W (84.5 ± 30.1 vs. 141.0 ± 13.7, Watt, p =0.0001) during cycle ergometer test were significantly lower in MS compared with HP. Similarly, the VO2peak in MS during arm crank was significantly lower (16.7 ± 5.4 vs. 23.4 ± 5.1 ml·kg·min-1, p = 0.023) compared with HP. However, the power generated by the arm was not different between the groups. CONCLUSION: The patients with MS during leg ergometer test showed a lower VO2peak. In the same sense, the patients with MS showed lower VO2peak in the test performed with the arms. Interestingly, the power generated with arms was similar in the two groups. These results indicate, that the patients with MS reflect a greater affectation to produce high loads of physical work with legs but not with arms. Further research is suggested where both the lower and upper extremities are involved to improve the processes of rehabilitation in MS

The feeding of American plaice (Hippoglossoides platessoides), Redfish (Sebastes marinus) and Cod (Gadus morhua) in the Flemish Cap during July 1988

A randomly stratified bottom-trawl survey was realized in the Flemish Cap (NAFO Div. 3M) in July 1988. The stomach contents of three species were studied: 320 of American plaice (Hippoglossoides platessoides), 203 of redfish (Sebastes Marinus) and 468 of cod (Gadus morhua). The cod specimens were classified taking into account age groups; in the case of other species by length classes. The food items, the prey occurrence index and the diversity index were determined too. The Schoener overlap index was calculated to study the intraspecific diet overlap in cod and the interspecific diet overlap between the three species. The relation between predator size (cod) and prey size (redfish) was also studied

DEPM 2014. Preliminary Egg Results for the Atlanto-Iberian Sardine ICES VIII and IXa

The triennial DEPM for estimation of sardine spawning biomass for the Atlanto-Iberian stock areas IXa – VIIIc and VIIIb up to 45 º N took place in the S and W (IPMA) from 15th March to 26th April and in the N (Galicia, Cantabrian Sea and French coast, IEO) between 29th March and 21st April. The whole area was surveyed however the Portuguese survey occurred much later than usual and suffered several interruptions; part of IPMA´s DEPM survey was conducted simultaneously to the acoustics survey onboard the same vessel. The number of fishing samples was maintained at levels similar to other years but it was evident that sardine schools were less available than during previous surveys in particular in the western and northern shores. Preliminary estimates highlighted a sharp decrease in egg production from 2011 to 2014; this pattern was particularly clear in the northern stratum

No evidence that wild red deer (Cervus elaphus) on the Iberian Peninsula are a reservoir of Mycobacterium avium subspecies paratuberculosis infection

The potential role of red deer (Cervus elaphus) as a reservoir of Mycobacterium avium subspecies paratuberculosis (MAP) infection is largely unknown. A total of 332 wild red deer were investigated using post-mortem examination, bacteriology and serology. Only three animals (1.12%) were found to have lesions on histopathological examination and no MAP bacteria were recovered on culture. The results suggest it is unlikely that wild red deer make a significant contribution to the maintenance of MAP infection in the region. The cross-reactivity of the ELISAs used indicates this diagnostic modality is ineffective in the detection of MAP infection in this species. The implications of these results for the control of this important pathogen in both livestock and wildlife are discussed.This research was supported by MCINN Grants AGL2008-03875/FEDER and FP7EU/TB-STEP-212414.Peer Reviewe
