Ecological distribution of the shrimp Pleoticus muelleri (Bate, 1888) (Decapoda : Penaeoidea) in southeastern Brazil

The abundance and ecological distribution of the shrimp Pleoticus muelleri as a function of certain environmental factors were investigated from January 1998 through December 1999 in the region of Ubatuba, São Paulo, Brazil. The collections were made monthly in the bays of Ubatumirim (UBM), Ubatuba (UBA) and Mar Virado (MV). Each bay was divided into six sampling transects, four transects parallel to the shoreline and two near the rocky shores on the opposite side. We employed a commercial shrimp boat equipped with two double-rig nets. A total of 6252 shrimp were collected, including 3321 from MV, 1467 from UBM, and 1464 from UBA. Most of the shrimp were caught in the deeper, higher-salinity areas. The high abundance of P. muelleri observed in the southern part of the region studied was related to a sediments with a higher percentage of silt and clay. The numbers of P. muelleri were positively correlated with periods of cooler temperatures. Thus, temperature and the type of sediment were determinant factors in the distribution of P. muelleri in this region.

Treatment of urinary stress incontinence by intravaginal electrical stimulation and pelvic floor physiotherapy

Treatment of urinary stress incontinence (USI) by intravaginal electrical stimulation (IES) and pelvic floor physiotherapy represents an alternative to other therapies. The purpose of this work was to evaluate the effectiveness of this treatment inpatients with urinary incontinence. From January 1998 to May 2000, 30 women (mean age 54 years) were studied. All patients had USI and 70% urge incontinence; average follow-up was 7 months. Selection criteria were based on clinical history, objective evaluation of perineal musculature by perineometry, and urodynamics. The treatment protocol consisted of three sessions of IES per week for 14 weeks using INNOVA equipment. Physiotherapy was initiated in the fifth week of IES. A significant decrease in the number of micturitions and urgency was observed after treatment (P<0.01). The pad test showed a reduction in urinary leakage from 13.9 to 5.9 g after treatment (P<0.01). Objective evaluation of perineal muscle strength showed a significant improvement in all patients after treatment (P<0.01). A positive correlation was observed between maximum flow rate (Q(max)) and all three variables: urethral pressure profile at rest and on straining (stop test), and abdominal leak-point pressure (ALPP). A positive correlation was also observed between ALPP and the stop test. Over 100 different surgical and conservative treatments have been tried to manage USI. The majority of these procedures reveal that despite progress already made in this area, there is no ideal treatment. Satisfactory results can be achieved with this method, especially with patients who are reluctant to undergo surgery because of personal or clinical problems.

Inter and intraspecific variation on reproductive phenology of the Brazilian Atlantic forest Rubiaceae: Ecology and phylogenetic constraints

The reproductive phenology of seven species of Rubiaceae from the Brazilian Atlantic rain forest was compared to evaluate the occurrence of phylogenetic constraints on flowering and fruiting phenologies. Since phenological patterns can be affected by phylogenetic constraints, we expected that reproductive phenology would be similar among plants within a family or genus, occurring during the same time (or season) of the year. Observations on flowering and fruiting phenology were carried out monthly, from December 1996 to January 1998, at Núcleo Picinguaba, Parque Estadual da Serra do Mar, Ubatuba, São Paulo State, Brazil. Nine phenological variables were calculated to characterize, quantify and compare the reproductive phenology of the Rubiaceae species. The flowering patterns were different among the seven species studied, and the Kruskal-Wallis test indicated significant differences in flowering duration, first flowering, peak flowering and flowering synchrony. The peaks and patterns of fruiting intensity were different among the Rubiaceae species studied and they differed significantly from conspecifics in the phenological variables fruiting duration, fruiting peak date, and fruiting synchrony (Kruskal-Wallis test). Therefore, we found no evidence supporting the phylogenetic hypotheses, and climate does not seem to constrain flowering and fruiting patterns of the Rubiaceae species in the understory of the Atlantic forest.

Reproductive biology of the shrimp Rimapenaeus constrictus (Decapoda, Penaeidae) in the ubatuba region of Brazil

Sexual maturity, temporal reproductive pattern, and recruitment of juveniles were examined for the shrimp Rimapenaeus constrictus at three different bays in the Ubatuba region (Mar Virado, Ubatuba, and Ubatumirim), State of São Paulo (23°S 45°W). Monthly samples were taken from January 1998 to December 1999. The presence or absence of mating plugs (associated with mating and insemination) and ovarian maturity were used to examine breeding in adult females. The whole sample comprised 3863 females and 1468 males. Estimates of size (carapace length) at the onset of sexual maturity were 7.0 mm and 7.8 mm for males and females, respectively. Higher percentage of females bearing ripe gonads was observed during spring and summer over the course of the study, contrasting to the low proportion in fall 1998 and winter 1999. Juvenile shrimps were sampled year-round. These results suggest a continuous reproductive pattern for R. constrictus. Mating, spawning, and juvenile recruitment took place mostly in shallow waters up to 20-m depths in the study region. Warm to mild temperatures may favour the spawning pattern observed in this species. The classical paradigm of continuous reproduction at lower latitudes, with increased seasonality of breeding period at higher latitudes, seems to apply to this species.

Diphyllobothriasis, Brazil

Cases of human diphyllobothriasis have been reported worldwide. Only 1 case in Brazil was diagnosed by our institution from January 1998 to December 2003. By comparison, 18 cases were diagnosed from March 2004 to January 2005. All patients who became infected ate raw fish in sushi or sashimi.

Missing association between telomerase activity and clinicopathological features in patients with early stage carcinoma of the cervix

Objectives: This study was undertaken to evaluate the association between the telomerase activity in the tumor and clinicopathological findings in patients with stage IB-IIA (FIGO) carcinoma of the cervix. Methods: Thirty-eight patients with carcinoma of the cervix submitted to radical hysterectomy were prospectively from January 1998 to November 2001. Samples from the tumor were taken and analyzed by the telomerase PCR-TRAP-ELISA kit. Clinicopathological characteristics such as age, stage, tumor size, grade of differentiation, lymphatic vascular space invasion (LVSI), parametrial involvement and status of pelvic lymph nodes were also recorded. Results: Patient's mean age was 49.3 ± 1.99 years (29-76 years). The clinical stage (FIGO) was IB in 35 patients (92.1%) and IIA in 3 patients (7.9%). The histological classification identified squamous cell carcinoma in 33 patients (86.8%) and adenocarcinoma in 5 patients (13.2%). There was no association between age, clinical stage, histological classification, tumor size, grade of differentiation and presence of LVSI with tumoral telomerase activity. The telomerase activity was not associated with the presence of vaginal involvement (P = 0.349), parametrium involvement (P = 0.916), pelvic lymph node metastasis (P = 0.988) or tumoral recurrence (P = 0.328) in patients with carcinoma of the cervix. Conclusions: Telomerase activity in the tumor is not associated with clinicopathological findings or tumor recurrence in patients with early stage cervical carcinoma. © 2006 Springer-Verlag.

Species distribution and susceptibility profile of Candida species in a Brazilian public tertiary hospital

Background. Species identification and antifungal susceptibility tests were carried out on 212 Candida isolates obtained from bloodstream infections, urinary tract infections and dialysis-associated peritonitis, from cases attended at a Brazilian public tertiary hospital from January 1998 to January 2005. Findings. Candida albicans represented 33% of the isolates, Candida parapsilosis 31.1%, Candida tropicalis 17.9%,Candida glabrata 11.8%, and others species 6.2%. In blood culture, C. parapsilosis was the most frequently encountered species (48%). The resistance levels to the antifungal azoles were relatively low for the several species, except for C. tropicalis and C. glabrata. Amphotericin B resistance was observed in 1 isolate of C. parapsilosis. Conclusions. The species distribution and antifungal susceptibility herein observed presented several epidemiological features common to other tertiary hospitals in Latin American countries. It also exhibited some peculiarity, such as a very high frequency of C. parapsilosis both in bloodstream infections and dialysis-associated peritonitis. C. albicans also occurred in an important number of case infections, in all evaluated clinical sources. C. glabrata presented a high proportion of resistant isolates. The data emphasize the necessity to carry out the correct species identification accompanied by the susceptibility tests in all tertiary hospitals. © 2010 Bagagli et al; licensee BioMed Central Ltd.

Psychosocial impact on anophthalmic patients wearing ocular prosthesis

The aim of this study was to assess the improvement in psychosocial awareness of anophthalmic patients wearing ocular prostheses and its relationship with demographic characteristics, factors of loss/treatment, social activity, and relationship between professional and patient. Surveys including a form for evaluation of psychosocial pattern were conducted with 40 anophthalmic patients rehabilitated with ocular prosthesis at the Center of Oral Oncology in the authors' dental school from January 1998 to November 2010. The improvement in psychosocial awareness was assessed by comparing the perception of some feelings reported in the period of eye loss and currently. Wilcoxon tests were applied for comparison of patients' perception between the periods. χ2 tests were used to assess the relationship between the improvement in psychosocial awareness and the variables of the study. In addition, the logistic regression model measured this relationship with the measure of odds ratio. The feelings of shame, shyness, preoccupation with hiding it, sadness, insecurity and fear were significant for improvement in psychosocial awareness. It was concluded that the anophthalmic patients wearing an ocular prosthesis has significant improvement in psychosocial awareness after rehabilitation. © 2012 International Association of Oral and Maxillofacial Surgeons.

Estudo comparativo da distribuição espaço-temporal da precipitação na Amazônia Oriental

Este trabalho utilizou os dados de precipitação do período de janeiro de 2000 a setembro de 2007 da torre micrometeorológica localizada na Estação Científica Ferreira Pena (ECFP) em Caxiuanã e foram comparados com o algoritmo 3B42 que combina dados de satélites no canal de microoondas para ajustar aqueles do canal infravermelho. Adicionalmente foi feita uma análise da distribuição temporal e espacial da precipitação na Amazônia Oriental utilizando os dados de cinco algoritmos estimadores de precipitação: O Geostationary Environmental SalellitePrecipitation lndex (GPI); o 3B42; 3A12 e 3A25 que são os algoritmos provenientes dos sensores de microondas e do radar meteorológico à bordo do satélite Tropical Rainfall MeasuringMission (TRMM); e o Global Precipitation Climatology Center (GPCC) de janeiro de 1998 a dezembro de 2007. A comparação entre o algoritmo 3B42 com os dados do pluviógrafo da torre mostrou que o estimador 3B42 superestima a precipitação em relação aos dados da torre para todo o período de estudo. Os períodos mais chuvosos foram os trimestres de março-abril-maio (MAM) e dezembro-janeiro-feveireiro (DJF) e os períodos menos chuvosos foram setembro-outubro-novembro (SON) e junho-julho-agosto (JJA). Esta sazonalidade da precipitação se apresenta principalmente devido à influência da Zona de Convergência Intertropical (ZCIT), que contribui de maneira apreciável para a modulação da estação chuvosa na região. A comparação trimestral entre o algoritmo 3B42 e pluviógrafo da torre, mostra que o algoritmo 3B42 superestimou (subestimou) a precipitação em relação ao pluviógrafo em MAM e JJA (DJF e SON); e DJF é o trimestre que apresenta as estimativas de precipitação com valores mais aproximados a precipitação medida na torre micrometeorológica de Caxiuanã. Na média mensal o 3B42 subestima a precipitação de outubro a janeiro e superestima em relação as dados medidos na torre, de março a agosto. O algoritmo3B42 superestimou (subestimou) a precipitação noturna (matutina e vespertina) do ciclo diurno em relação ao pluviógrafo da torre, nas vizinhanças de Caxiuanã. No entanto ambos estimadores mostraram que em média o horário de maior precipitação é por volta das 1800hora local (HL). Além disso, as análises do ciclo diurno médio sazonal indicam que em DJF nos horários de 0900 HL, 1500 HL e 1800HL têm os valores de precipitação estimada pelo algoritmo3B42 mais aproximados aos valores da precipitação medida pontualmente em Caxiuanã. Os meses de novembro a fevereiro têm um máximo principal de precipitação no período vespertino, tanto na torre como no algoritmo 3B42. No período de maio à julho o horário os máximos diurnos de precipitação passam do período da tarde para os da noite e madrugada,modificando o ciclo diurno em comparação aos demais meses. A comparação entre os cinco algoritmos na Amazônia Oriental mostrou diferentes comportamentos entre os estimadores. O algoritmo GPI subestimou s precipitação em relação aos demais algoritmos na região costeira do Amapá e Guiana Francesa e superestimou na região central da Amazônia. Tanto o algoritmo 3A12 quanto o 3A25 apresentaram menor precipitação que os demais algoritmos. O algoritmo 3842, por ser uma combinação de várias estimativas baseadas no canal de microondas e infravermelho, apresenta padrões semelhantes a Figueroa e Nobre (1990). No entanto, o GPCC mostra menos detalhes na distribuição espacial de precipitação nos lugares onde não há pluviômetros como, por exemplo, no Noroeste do Pará. As diferenças entre os algoritmos aqui considerados podem estar relacionados com as características de cada algoritmo e/ou a metodologia empregada. As comparações pontuais de precipitação de um pluviômetro com a média numa área com dados provenientes de satélites podem ser a explicação para as diferenças entre os estimadores nos trimestres ou ciclo diurno. No entanto não se descartam que essas diferenças sejam devidas à diferente natureza da precipitação entre as subregiões, assim como a existência de diferentes sistemas que modulam o ciclo diurno da precipitação na Amazônia Oriental.
