Description of Simulium damascenoi (Diptera: Simuliidae) male and the black-fly species from the State of Amapá, Brazil

Five species are included in the Simulium siolii group, which is placed in the subgenus Psaroniocompsa (Diptera: Simuliidae). Of these five species, only two (Simulium siolii Py-Daniel and Simulium tergospinosum Hamada) have been described in all their life stages, except eggs. Knowledge of the taxonomic characters of all life stages of a species is important in order to clarify interspecific and higher-level taxonomic relationships. The objectives of the present study are to describe the male of Simulium damascenoi Py-Daniel, to provide a list of black-fly species their bionomics and distributions in the state of Amapá, Brazil, and to provide an identification key for larvae and pupae for these species.

Description of the female of Sciopemyia servulolimai (Damasceno & Causey) (Diptera: Psychodidae)

The female of Sciopemyia servulolimai (Damasceno & Causey), based on three specimens captured during an epidemiological research project in the state of Ceará, Brazil, is described and illustrated for the first time.

Taxonomic studies on Culex (Melanoconion) coppenamensis Bonne-Wepster & Bonne (Diptera: Culicidae), and description of two new species from Brazil

Two new species,Culex (Melanoconion) alinkios and Culex (Melanoconion) symbletos are described and defined based on morphological features of the male genitalia. The former is from Vale do Ribeira, Atlantic Forest, southeastern of the state of São Paulo, Brazil, and belongs to the Bastagarius subgroup. The latter is from the Parque Nacional do Jaú, state of Amazonas, Brazil, and belongs to the Inhibitator subgroup and is similar to Cx. mesodenticulatus Galindo and Mendez. Diagnostic characters for the identification of the adult males of the species are provided. Two morphological forms (Form 1 and 2), which are similar to Cx. coppenamensis, were also found in the Parque Nacional do Jaú. Form 1 is described and compared with the new species from Vale do Ribeira and Form 2.

Respiratory syncytial virus infections during an epidemic period in Salvador, Brazil: viral antigenic group analysis and description of clinical and epidemiological aspects

Acute respiratory infections (ARI) caused by respiratory syncytial virus (RSV) were studied in 482 children from Salvador, BA, Brazil, over a period of 12 months. The epidemic period of RSV infections in Salvador occurred from February (summer) to August (winter), with peaks in May, June, and July. The grouping characteristics of 84 RSV present in nasopharyngeal secretions of children seen at a reference university hospital were analyzed. RSV represented 17.4% of all cases and 54.5% of the positive samples. Sixty-four RSV strains were assigned to group A and 14 to group B. Both groups circulated in the five months of the epidemic period studied. Infections by both groups of RSV were more frequent in children up to one year of age. The incidence of RSV ARI was slightly more frequent in males, although group B had more infected females.

The subgenus Scaptia (Lepmia) fairchild: redescription of females and description of a male (Diptera: Tabanidae: Pangoniinae)

The subgenus Scaptia (Lepmia) Fairchild, known only from mountanous areas of Southeast of Brazil, is redescribed and illustrated. It is contrasted with similar species of Scaptia (Pseudoscione). It is more similar to the Australian Myioscaptia and Plinthina than to the other New World Scaptia subgenera.

Terrestrial mammal feces: a morphometric summary and description

The study of feces of terrestrial mammals brings out biological and ecological data such as the species presence, diet, behaviour, territory, parasitic fauna, and home-range use, which can be applied for conservation projects and support paleoecological research that use coprolites as the main source of study. Although the new biotechnological techniques allow more accurate data, the diagnosis based on morphometric analyses permits the primary identification of the taxonomic group origin to support the best choice of subsequent analyses. We present the compilation list of fecal shape and measurements available in the literature published in North America, Eastern and Southern Africa, Europe, and new data from Brazil. Shape and diameters are the best characteristics for taxonomic identification. Feces were assembled in 9 groups that reflect the Order, sometimes the Family, and even their common origin.

Ultrasound-guided suprascapular nerve block, description of a novel supraclavicular approach.

BACKGROUND AND OBJECTIVES: The suprascapular nerve (SSN) block is frequently performed for different shoulder pain conditions and for perioperative and postoperative pain control after shoulder surgery. Blind and image-guided techniques have been described, all of which target the nerve within the supraspinous fossa or at the suprascapular notch. This classic target point is not always ideal when ultrasound (US) is used because it is located deep under the muscles, and hence the nerve is not always visible. Blocking the nerve in the supraclavicular region, where it passes underneath the omohyoid muscle, could be an attractive alternative. METHODS: In the first step, 60 volunteers were scanned with US, both in the supraclavicular and the classic target area. The visibility of the SSN in both regions was compared. In the second step, 20 needles were placed into or immediately next to the SSN in the supraclavicular region of 10 cadavers. The accuracy of needle placement was determined by injection of dye and following dissection. RESULTS: In the supraclavicular region of volunteers, the nerve was identified in 81% of examinations (95% confidence interval [CI], 74%-88%) and located at a median depth of 8 mm (interquartile range, 6-9 mm). Near the suprascapular notch (supraspinous fossa), the nerve was unambiguously identified in 36% of examinations (95% CI, 28%-44%) (P < 0.001) and located at a median depth of 35 mm (interquartile range, 31-38 mm; P < 0.001). In the cadaver investigation, the rate of correct needle placement of the supraclavicular approach was 95% (95% CI, 86%-100%). CONCLUSIONS: Visualization of the SSN with US is better in the supraclavicular region as compared with the supraspinous fossa. The anatomic dissections confirmed that our novel supraclavicular SSN block technique is accurate.

Description of Micropygomyia (Silvamyia) echinatopharynx sp. nov. (Diptera: Psychodidae) a new species of phlebotomine sand fly from the State of Tocantins, Brazil

During a study of the phlebotomines of the Brazilian state of Tocantins, a new species was discovered in Porto Nacional county, here described as Micropygomyia (Silvamyia) echinatopharynx sp. nov. This is only the second species of the subgenus Micropygomyia (Silvamyia) to be described.

The Genus Cyclospora (Apicomplexa: Eimeriidae), with a description of Cyclospora schneideri n.sp. in the snake Anilius scytale scytale (Aniliidae) from Amazonian Brazil: a review

A review is made of the recorded species of the coccidian genus Cyclospora and major events leading up to the discovery of C. cayetanensis, which is responsible for serious outbreaks of diarrhoea in man and is one of the aetiological agents of "traveller's diarrhoea". Humans appear to be the specific hosts, with the entire life-cycle in the intestine: to date there is no convincing evidence that the disease is a zoonosis. A description is given of oocysts and endogenous stages of C. schneideri n.sp., in the snake Anilius scytale scytale. Sporulation is exogenous and completed after about one week at 24-26º. Mature oocysts 19.8 × 16.6 (15.1 × 13.8-25.7 × 20.1), shape-index 1.2 (1.0-1.3): no oocyst residuum or polar bodies. Oocyst wall a single colourless, smooth layer with no micropyle: it is rapidly deformed or broken. Sporocysts 13.6 × 9.4 (11.3 × 8.3-15.1 × 9.9), shape-index 1.4 (1.2-1.5) with an inconspicuous Stieda body. Sporozoites 11-13 × 2.5-3. Endogenous stages are intracytoplasmic in the epithelial cells of the small intestine and with the characters of the Eimeriorina.

Inventory and description of disease management programs in Switzerland

Background: Disease management, a system of coordinated health care interventions for populations with chronic diseases in which patient self-care is a key aspect, has been shown to be effective for several conditions. Little is known on the supply of disease management programs in Switzerland. Objectives: To systematically search, record and evaluate data on existing disease management programs in Switzerland. Methods: Programs met our operational definition of disease management if their interventions targeted a chronic disease, included a multidisciplinary team and lasted at least 6 months. To find existing programs, we searched Swiss official websites, Swiss web-pages using Google, medical electronic database (Medline), and checked references from selected documents. We also contacted personally known individuals, those identified as possibly working in the field, individuals working in major Swiss health insurance companies and people recommended by previously contacted persons (snow ball strategy). We developed an extraction grid and collected information pertaining to the following 8 domains: patient population, intervention recipient, intervention content, delivery personnel, method of communication, intensity and complexity, environment and clinical outcomes (measures?). Results: We identified 8 programs fulfilling our operational definition of disease management. Programs targeted patients with diabetes, hypertension, heart failure, obesity, alcohol dependence, psychiatric disorders or breast cancer, and were mainly directed towards patients. The interventions were multifaceted and included education in almost all cases. Half of the programs included regularly scheduled follow-up, by phone in 3 instances. Healthcare professionals involved were physicians, nurses, case managers, social workers, psychologists and dietitians. None fulfilled the 6 criteria established by the Disease Management Association of America. Conclusions: Our study shows that disease management programs, in a country with universal health insurance coverage and little incentive to develop new healthcare strategies, are scarce, although we may have missed existing programs. Nonetheless, those already implemented are very interesting and rather comprehensive. Appropriate evaluation of these programs should be performed in order to build upon them and try to design a generic disease management framework suited to the Swiss healthcare system.

Description of Pintomyia (Pifanomyia) brazilorum sp. nov. a new fossil species from the Dominican Republic (Diptera: Psychodidae: Phlebotominae)

A sand fly fossil was found in amber, a vegetal resin, which allows all the external phlebotomine structures to be seen. The piece that contains the new species is 14 mm long ´ 8 mm wide ´ 3 mm high. All the structures from the head, thorax, and abdomen were examined under the microscope and measured with a calibrated micrometric eye-piece. The morphological aspects of the new species suggest its inclusion in the Pintomyia genus, Pifanomyia subgenus though it is not possible to include it in any of the series known for this subgenus. The presence of two atrophied spines on the gonostyles and gonocoxites without tufts of setae permit the exclusion of the new species from the other species of the subgenus Pifanomyia. The new species is named Pintomyia (Pifanomyia) brazilorum sp. nov.

Tabanidae (Diptera) of Amazônia XX: description of Tabanus pseudonebulosus n.sp.

Tabanus pseudonebulosus, new species, is described based on 217 female specimens and 5 males collected in Venezuela (Guarico, Aguaio, Santa Elena, and Palmarito) and in Brazil (Pará: Santana do Araguaia, Serra das Andorinhas in São Geraldo do Araguaia, Serra Norte Carajás and Gorotire; Amazonas: Canutama; Mato Grosso do Sul: Corumbá), mostly in open vegetation, scrub forest and in rocky environments. Observed intraspecific variation in the specimens is presented and related to collection localities, and morphological differences are diagnosed in relation to the similar species Tabanus nebulosus DeGeer 1776 and T. importunus Wiedemann 1828. Morphometrical data and indices for specimens in different localities are provided. Drawings and photo of the new species are presented.

Pâturages et pelouses oligotrophes calcicoles du Haut-Jura vaudois: description et écologie

Oligotrophic, lowland and montane meadows and pastures in the Jura Mountains have been well studied, but little is known about subalpine pastures and meadows, especially in Western Switzerland. This paper describes the different types of calcicolous, oligotrophic pastures and meadows found in the "Parc jurassien vaudois" (canton of Vaud). Eight plant communities are described: Gentiano-Brometum acinetosum at montane and Alchemillo-Seslerietum prunelletosum at subalpine altitudes, Alchemillo- Seslerietum festucetosum on shallower soil, Sedo-Poetum acinetosum on very shallow soil, Ranunculi- Agrostietum traunsteineretosum on clayey soil on southern exposures, Seslerio-Laserpitietum on steep and stony southern exposed slopes, a Festuca pulchell a and Pulsatilla alpina community on northern exposed scree, and Laserpitio-Calama- grostietum on more stable scree. Many of these meadows and pastures are very species-rich and deserve protection. Two floristic comparisons complete this paper. The first looks at the transition zone between montane pastures (Mesobromion) and subalpine pastures (Seslerion), and sets the limit around 1350 m, with some variation due to aspect and soil. The second compares the main subalpine pasture community (Alchemillo- Seslerietum prunelletosum) in the Jura Mountains with its vicariant (Seslerio-Caricetum sempervirentis) in the Alps.
