RESUMO
Citrus leprosis is a viral disease vectored by the mites Brevipalpus californicus and Brevipalpus yothersi. This work aimed to determine the potential areas for establishment of both mites and viruses in Mexico, based on the geographical distribution of the hosts and the climatic suitability for the vectors. Life tables of both mites were constructed to determine their thermal requirements-base temperature and degree-days required to complete life cycle-and population growth parameters-net reproduction rate, generation time, and intrinsic growth rate. For this, the mites were confined in Citrus aurantium fruits at 20, 22.5, 25 or 30 °C, 60 ± 5% RH and L14:D10 h photoperiod. Maps were generated where the climatic suitability for establishment of the mites and the citrus leprosis viruses was estimated in citrus-producing municipalities. The climatic suitability was determined through historical temperature records to calculate the potential number of generations per year, and ecological niche modeling based on collecting localities and bioclimatic variables using the algorithm Maxent. The base temperature was 9.5 °C for B. californicus and 10.2 °C for B. yothersi; degree-days required to reach adulthood were 372.1 and 331.7 °C, respectively. Potential sites for establishment of B. yothersi are mostly lowlands, whereas for B. californicus they are both lowlands and highlands. Temperature data indicate that B. californicus has fewer sites where it can develop > 16 generations per year than B. yothersi. According to our results, the sites where citrus leprosis is most likely to present high incidence are the sweet orange cultivars bordering the Gulf of Mexico.

ABSTRACT Objective: To determine the incidence and rate of disc degeneration adjacent to a lumbar fusion, as well as to analyze possible risk factors for its development. Methods: A retrospective study of a level of evidence IIB case series of 125 patients diagnosed with lumbar canal stenosis and spondylolisthesis, who underwent surgery from January 2011 to December 2016, with subsequent instrumentation and posterolateral fusion and outpatient follow-up in which the symptomatology and radiographic findings were evaluated to establish the diagnosis and management. Results: Twelve patients with adjacent segment disease were identified, with an incidence of 9.6%, higher both among female patients and in the seventh decade of life. The most frequent pathology was canal stenosis (42.4%), the most affected level was L4 / L5, and the procedure most associated with the prevalence of adjacent level degeneration was L4-L5 posterior transpedicular instrumentation. Conclusions: Sagittalization of the facet joint was a constant factor in all patients with involvement of the adjacent disc. The main clinical findings were treatment-resistant root pain and radiographic alterations characterized by spondylolisthesis, facet osteoarthritis and intervertebral disc herniation. Level of Evidence IIB; Retrospective study.

ABSTRACT Objective: The objective of this longitudinal retrospective study is to assess the efficacy and safety of total lumbar disc replacement in patients with degenerative discopathy (L3-L4, L4-L5, L5-S1). Methods: One hundred and forty-three patients with low back pain, with or without radiculopathy, who met the radiographic criteria underwent anterior arthroplasty between 2000 and 2016. The Oswestry disability index (ODI), the visual analog scale (VAS), patient satisfaction, success criteria, disc height, and range of motion of the operated segment were evaluated preoperatively and at 3, 6, 12, and 24 months following surgery. Results: There were 50 men and 93 women, with an average age of 39.5 years, 13 patients (9%) with previous discectomy. The arthroplasty was performed at level L5-S1 in 97 patients (67.8%), at level L4-L5 in 45 patients (31.5%), and at level L3-L4 in 1 patient. Between the preoperative period and 24 months following surgery, the ODI decreased by 53.86%, the VAS for low back pain decreased by 63.83%, and low back pain with radiculopathy decreased by 60.20%, all statistically significant (p ≤ 0.5). Eighty-two percent of the patients were completely satisfied and 18% were satisfied. There was an average increase in disc height of 12 mm (p <0.001). The range of motion of the affected segment increased by 4° to 7° after surgery (p <0.004). Conclusions: Lumbar arthroplasty of a segment is recommended as an effective treatment for patients with degenerative disc disease with low back pain with or without a root component who meet the inclusion criteria.

Reproductive phenology is an important trait subjected to natural selection. Current horses in America belong to the Palearctic original populations after being introduced by European colonizers. Photoperiod variation is the main environmental factor for the adjustment of reproductive timing in horses, but is absent in equatorial areas. Here we hypothesize that seasonality of green-grass availability may influence breeding phenology in equatorial regions. We used data of 929 services to mares from 2006 to 2011 in a thoroughbred equine exploitation in Ecuador that experienced strong grass seasonality. Actual births could not be used to infer natural phenology because they were influenced by management decisions. Instead, we used variations in the probability of pregnancy after a service as a measure of the natural tendency of mares to show breeding phenology. We found that although managers tended to schedule pregnancies in two periods within the year, mares were more prone to become pregnant after the increase in grass greenness that takes place at the beginning of the year (February). Our finding has potential applications to improve the success of services and the welfare of animals, by providing green-grass stimuli in the appropriate season.

Horse reproduction tends to be seasonal. The main adjusting factor in their original temperate ranges is photoperiod variation, although it is absent in equatorial areas where horses were introduced by European colonizers. Hence, dates of reproduction in these areas may be influenced by factors affecting mares' conditions and the success of foaling. Here we study reproductive timing in Creole horses in Ecuador reared in an extensive production system. We found that foaling peaked in August. Mares' conditions showed one peak in June-July, before the start of the breeding season, and another in December, and it was highly variable along the year. Mares' conditions increased after a period of vegetation growth and thus appeared negatively associated with the increment of grass greenness (normalized difference vegetation index data). Seasonal flooding of some pasturelands during March and April appeared to seriously impair mares' conditions and probably influenced the timing of foaling toward the dry season. Our results evidenced that horse breeding in these equatorial areas tended to be seasonal and point to some key factors that influence phenology by affecting body condition of mares, which may have implications for horse biology and management.

ABSTRACT Objective: To analyze the functional outcome of surgical treatment of cervical spondylotic myelopathy. Methods: A retrospective study involving 34 patients with CSM, operated from January 2014 to June 2015. The neurological status was assessed using the Nurick and modified Japanese Orthopedic Association (mJOA) scales preoperatively and at 12 months. Sex, age, time of evolution, affected cervical levels, surgical approach and T2-weighted magnetic resonance hyperintense signal were also evaluated. Results: A total of 14 men and 20 women participated. The mean age was 58.12 years. The average progression time was 12.38 months. The preoperative neurological state by mJOA was mild in 2 patients, moderate in 16 and severe in 16, with a mean of 11.44 points. The preoperative Nurick was grade II in 14 patients, grade III in 8, grade IV in 10 and grade V in 2. The T2-weighted hyperintense signal was documented in 18 patients (52.9%). The functional outcome according to the mJOA recovery rate was good in 15 patients (44.1%) and poor in 19 (55.9%). The degree of Nurick recovery was good in 20 (58.8%) and poor in 14 (41.2%). Conclusions: Decompressive surgery of the spinal cord has been shown to be effective in the treatment of cervical spondylotic myelopathy in well-selected patients. Although it is suggested that there are certain factors that correlate with functional outcome, we believe that more prospective randomized studies should be conducted to clarify this hypothesis.
RESUMO Objetivo: Analisar o resultado funcional do tratamento cirúrgico da mielopatia espondilótica cervical. Métodos: Estudo retrospectivo envolvendo 34 pacientes com MEC submetidos a cirurgia de janeiro de 2014 a junho 2015. O estado neurológico foi avaliado utilizando as escalas de Nurick e da Japanese Orthopaedic Association modificada (mJOA) no pré-operatório e aos 12 meses. Sexo, idade, tempo de evolução, níveis cervicais afetados, via de acesso cirúrgico e sinal de hiperintensidade na ressonância magnética ponderada em T2 também foram avaliados. Resultados: Foram incluídos 14 homens e 20 mulheres. A média de idade foi 58,12 anos. O tempo médio de progressão foi 12,38 meses. O estado neurológico pré-operatório por mJOA foi leve em 2 pacientes, moderado em 16 e grave em 16, com média de 11,44 pontos. O Nurick pré-operatório foi de grau II em 14 pacientes, grau III em 8, grau IV em 10 e grau V en 2. O sinal de hiperintensidade em T2 foi documentado em 18 pacientes (52,9%). O resultado funcional de acordo com a taxa de recuperação mJOA foi bom em 15 pacientes (44,1%) e ruim em 19 (55,9%); o grau de recuperação de Nurick foi bom em 20 (58,8%) e ruim em 14 (41,2%). Conclusões: A cirurgia descompressiva da medula espinal demonstrou ser eficaz no tratamento de mielopatia espondilótica cervical em pacientes bem selecionados. Embora se sugira que há certos fatores que se correlacionam com o resultado funcional, acreditamos que mais estudos prospectivos e randomizados devem ser conduzidos para esclarecer esta hipótese.

The purpose of this study was to assess the internal consistency and stability of the Five-Point Test (FPT), developed by Regard, Strauss, and Knapp (1982). A test of non-verbal fluency, the FPT is an executive measure that may be particularly useful in the evaluation of individuals with presumed frontal lobe damage. In the internal consistency study, 209 healthy participants were administered the FPT. A split-half analysis revealed a correlation of .80 for unique designs, and .48 for perseverative errors. In the stability study, 142 healthy participants were administered the FPT on two occasions with a mean interval of 37.8 days. Across the two administration periods, a test-retest correlation of .78 for unique designs and .51 for perseverative errors was found. When the mean performances were compared across administration periods, significant differences were found for unique designs, but not for percentage of perseverative errors. Taken together, the results of the two studies suggest that the internal consistency and stability coefficients of the FPT are acceptable for unique designs but low for the percentage of perseverative errors.

We report a case of botryomycosis and intestinal strongyloidiasis in apatient with HTLV-1 infection. A 23 year-old female patient from Ayacucho, came with a history of a right foot tumor and chronic foot ulcers. The diagnosis of botryomycosis was established by biopsy of the lesion. Because the mild eosinophilia, a microscopic examination of stools was performed and Strongyloides stercoralis rhabditiform larva were found. HTLV-1 ELISA test, performed in order to discharge association with strongyloidiasis, was positive. The clinical presentation, physiopathology of the botryomycosis and the role of the HTLV-1 infection and strongyloidiasis as predisposing factors for botryomycosis are discussed.
