Considerations about the recommendations of the Commission on the Limits of the Continental Shelf on the Amazon fan

In 2004, Brazil submitted to the Commission on the Limits of the Continental Shelf (CLCS) a Submission for the outer limit of the Brazilian continental shelf for its extension beyond the limits of 200 nautical miles. In 2007, the CLCS presented its recommendations, however it did not recommend four areas proposed by Brazil, the Amazon Fan among them. The objective of this study is to present the main legal and technical aspects of the controversy about the Amazon Fan, in order to evaluate some alternatives for a future submission, new or revised.

TWO NEW RECORDS OF Isomyia paurogonita FANG AND FAN, 1986 AND Sumatria latifrons Malloch, 1926 (DIPTERA: CALLIPHORIDAE) FROM NORTHERN THAILAND, WITH REVISED KEY TO THE SPECIES OF Isomyia

During the annual fly survey at Doi Nang Kaew in Doi Saket District, Chiang Mai Province of Thailand in 2011, Isomyia paurogonitaFang & Fan, 1986 (Diptera: Calliphoridae) and Sumatria latifrons Malloch, 1926 (Diptera: Calliphoridae) were collected for the first time in Thailand. They are the rare species of the subfamily Rhiniinae (tribe Cosminini). Prior to this finding, fifteen species of Isomyia and two species of Sumatriawere recorded from Thailand. Therefore, 96 blow fly species have been found in this country. These new locality records of both flies are very important for further research on their biology and ecology in Thailand.

India's homosexual discrimination and health consequences

A large number of countries worldwide have legalized homosexual rights. But for 147 years, since when India was a British colony, Section 377 of the Indian Penal Code defines homosexuality as a crime, punishable by imprisonment. This outdated law violates the fundamental rights of homosexuals in India. Despite the fact that literature drawn from Hindu, Buddhist, Muslim, and modern fiction testify to the presence of same-sex love in various forms, homosexuality is still considered a taboo subject in India, by both the society and the government. In the present article, the continuation of the outdated colonial-era homosexuality law and its impact on the underprivileged homosexual society in India is discussed, as well as consequences to this group's health in relation to HIV infection.

Life expectancy without depression increases among Brazilian older adults

ABSTRACT OBJECTIVE To estimate life expectancy with and without depressive symptoms in older adults for the years 2000 and 2010. METHODS We evaluated individuals aged 60 years or older (n = 1,862 in 2000 and n = 1,280 in 2010), participants of the Saúde, Bem-Estar e Envelhecimento (SABE – Health, Wellbeing and Aging) study in in Sao Paulo, Southeastern Brazil. Depression was measured using the shorter version of the Geriatric Depression Scale (GDS-15); respondents scoring ≥ 6 were classified as having depression. Estimates of life expectancy with and without depression were obtained using the Sullivan method. RESULTS Data from 2000 indicate that 60-year-old men could expect to live, on average, 14.7 years without depression and 60-year-old women could expect to live 16.5 years without depression. By 2010, life expectancy without depression had increased to 16.7 years for men and 17.8 years for women. Expected length of life with depression differed by sex, with women expected to live more years with depression than men. CONCLUSIONS Between 2000 and 2010, life expectancy without depression in Sao Paulo increased. However, older adults in Brazil, especially older women, still face a serious burden of mental illness.

Hemorrhagic syndrome and Acute renal failure in a pregnant woman after contact with Lonomia caterpillars: a case report

A case of a 37-week pregnant woman who developed a hemorrhagic syndrome and acute renal failure after contact with Lonomia caterpillars is reported. The accident also initiated labour and the patient gave birth to an alive child. Some pathophysiological aspects of the genital bleeding and of the acute renal failure are discussed.

Clinical and epidemiological features of definitive and presumed loxoscelism in São Paulo, Brazil

A retrospective study analysed 359 proven or presume cases of loxoscelism seen at the Hospital Vital Brazil, Instituto Butantan, São Paulo, Brazil, between 1985 and 1996. The spider was identified in 14%. The bites occurred predominantly in the urban areas (73%) between September and February. Patients > 14 years were commonest inflicted (92%) and 41% were bitten while getting dressed. Only 11% sought medical care within the first 12 hours post bite. Cutaneous loxoscelism was the commonest form presenting (96%); commonest manifestations were: pain (76%), erythema (72%), edema with enduration (66%), ecchymosis (39%). Skin necrosis occurred in 53% of patients, most frequently seen on trunk, tigh and upper arm, and when patients seek medical care more than 72 hours after bite. Local infection was detected in 12 patients (3%). Hemolysis was confirmed in 4 cases (1.1%). Generalised cutaneous rash, fever and headache were also observed in 48% of the total of patients. None of them had acute renal failure or died. Treatment usually involved antivenom administration (66%), being associated with corticosteroids (47%) or dapsone (30%). Presumptive diagnosis of loxoscelism may be established based on clinical and epidemiological findings. Further investigations are required to prove the value of antivenom and other treatment schedules.

Envenomation by Micrurus coral snakes in the Brazilian Amazon region: report of two cases

Two cases of proven coral snake bites were reported in Belém, Pará State, Brazil. The first case was a severe one caused by Micrurus surinamensis. The patient required mechanical ventilation due to acute respiratory failure. The second case showed just mild signs of envenomation caused by Micrurus filiformis. Both patients received specific Micrurus antivenom and were discharged without further complications. Coral snake bites are scarcely reported in the Amazon region and there is a broad spectrum of clinical manifestations, varying from extremely mild to those which may rapidly lead to death if the patient is not treated as soon as possible.

Provas de atividade inflamatória no pênfigo foliáceo endêmico

O pênfigo foliáceo endêmico (PFE) é uma afecção onde fenômenos auto-imunes são freqüentemente relacionados com sua patogênese. Abordaram-se neste estudo, alguns testes laboratoriais freqüentemente alterados em outras doenças auto-imunes. Foram estudados em 20 pacientes com PFE a presença ou alterações de fator antinúcleo (FAN), fator reumatóide (FR), proteína C-reativa (PCR), velocidade de hemossedimentação (VHS), eletroforese de proteínas e o número totalde leucócitos. Encontrou-se PCR positiva em mais de 65 % dos casos, leucocitose moderada na maioria dos pacientes, VHS aumentada e alterações discretas da análise de proteínas do sangue. O FAN e o FR apresentaram-se negativos em todos os casos. Embora estes exames sejam considerados inespecíficos, o seu estudo associado ao quadro clínico pode colaborar no acompanhamento do PFE.

Freqüência e implicações dos auto-anticorpos em hepatites agudas virais

Existem interações entre viroses hepatotrópicas e o sistema imunológico do hospedeiro que podem influenciar na patogenicidade da agressão hepática. O objetivo deste trabalho foi investigar a freqüência de auto-anticorpos na fase aguda da hepatite viral, sua relação com atividade bioquímica, gravidade da doença e cronicidade. Foram estudados 156 pacientes com hepatite aguda viral de 1992 a 2000. Destes, 32% tiveram infecção por vírus A, 31% por vírus B, 8% por vírus C, 3% tiveram hepatite E e 24% não A-E. Na fase aguda, 20,5% apresentaram FAN e 14,8% antimúsculo liso positivos. Na convalescença, 6,4% persistiram com FAN e 3,9% com antimúsculo liso positivos. Pacientes que persistiam com anticorpos detectáveis não apresentavam níveis de transaminases e bilirrubinas significativamente diferentes daqueles com auto-anticorpos negativos. Concluindo, os anticorpos que aparecem na fase inicial da infecção são transitórios e não têm implicação prognóstica.

Enterobius vermicularis infection is well controlled among preschool children in nurseries of Taipei City, Taiwan

INTRODUCTION: Whether Enterobius vermicularis (pinworm) infections among preschool children in Taipei City had truly declined was investigated. METHODS: A total of 6,661 preschool children from 28 nurseries were randomly selected from 4 major geographic districts in Taipei City to examine the status of pinworm infection by using adhesive thin cellophane tape swab method. RESULTS: The overall prevalence of pinworm infection was 0.5% (30/6,661). Boys (0.6%; 21/3,524) had higher prevalence than girls (0.3%; 9/3,137) (p=0.06). Southern district (0.6%; 10/1,789) showed insignificantly higher prevalence than Western district (0.2%; 1/606) (p=0.22). CONCLUSIONS: Pinworm screening program remains necessary for some parts of Taipei City.

Toxoplasma gondii infection: seroprevalence and associated risk factors among primary schoolchildren in Lagos City, Southern Nigeria

INTRODUCTION: Toxoplasma gondii infection has been described as the most widespread zoonotic infection of humans and other animals. Information concerning T. gondii infection among schoolchildren is unavailable in Lagos City, Nigeria. METHODS: This cross-sectional study investigated the seroprevalence and risk factors associated with T. gondii infection among primary schoolchildren (PSC) from a community located in the center of Lagos, southern Nigeria, from November 2013 to March 2014. A total of 382 PSC were screened for the presence of sera anti-T. gondii antibodies using a latex agglutination test (TOXO Test-MT, Tokyo, Japan). A cutoff titer of ≥ 1:32 was considered positive, while titers ≥ 1:1,024 indicated high responders. Questionnaires were also used to obtain data on possible risk factors from parents/guardians. RESULTS: The overall seroprevalence was 24% (91/382), and 83.5% (76/91) of seropositive PSC were classified as high responders. Among the risk factors tested, including contact with cats and soil, consumption of raw meat and vegetables, and drinking unboiled water, none showed statistical significance after multivariate adjustment. No associations were observed among age, gender, body mass index (BMI), and parents' occupation/educational level. CONCLUSIONS: The findings in this study show evidence of active infection, and hence, there is need for urgent preventive measures in this city. Further investigation is required to clarify the transmission routes. Policy makers also need to initiate prevention and control programs to protect pregnant women and immunocompromised patients in particular because they are more severely affected by T. gondii infection.

Small mammal abundances in isolated and non-isolated primary forest reserves near Manaus, Brazil

Abundances of msmall terrestrial mammals were estimated in 10 and 100-ha, isolated and non-isolated primary forest reserves near, Manaus, Brazil between October 1983 and March 1984. The smalt mammal abundance pattern In a 10 ha reserve isolated fan appoximately three years differed significantly from that in othen reserves, primarily due to higher capture rates of Marmosa cinerea, Rhipidomys mastacalis, and Onyzomys paricola in the isolated reserve. Viet type and re-invasion potential may be important factors the small mammal communities in forest patches. Variation the small mammal community among othen reserves was pnimanlty due to variatton In the abundances of Proechimys and 0. capito. At least pant of this vantation was attributable to temporal efects, but variation due to reserve effects also was suggested. Small mammals were much more abundant in the reserves during the present study than in 1982.

Cardiac tamponade in systemic lupus erythematosus. Report of four cases

OBJECTIVE: To report and assess the incidence of cardiac tamponade in systemic lupus erythematosus as a cardiac manifestation of the disease. METHODS: We reviewed the medical records of 325 patients diagnosed with systemic lupus erythematosus according to the American Rheumatism Association and their complementary laboratory tests compatible with cardiac tamponade. RESULTS: In the 325 medical recors reviewed, we found 108 patients with pericardial effusions corresponding to 33.2% of the total and 54% of the patients studied in the active phase of the disease. Clinical assessment and transthoracic echocardiogram allowed the clinical diagnosis of cardiac tamponade in only 4 (1.23%) patients, 3 of whom were females, white, with ages ranging from 25 to 44 years. The pericardial fluid was hemorrhagic or serosanguineous with high levels of FAN and positivity for LE cells. In the treatment, we successfully used pericardicentesis associated with high doses of corticosteroids. In clinical and laboratory follow-up performed for a period of 3 years, neither recrudescence of the pericardial effusion nor evolution to constriction occurred. CONCLUSION: Even though rare (1.23%), cardiac tamponade in patients with systemic lupus erythematosus has a benign evolution when properly treated, according to our experience.
