Epidemiological survey of skin diseases in schoolchildren living in the Purus Valley (Acre State, Amazonia, Brazil).

A total of 9,955 schoolchildren aged 6-16 years have been examined in a tropical region. The prevalence of dermatosis varied from 21 to 87% in the municipalities surveyed. The most common dermatoses were pediculosis (prevalence 50%), nevi (16.8%), pityriasis versicolor (13.2%), pyoderma (12.2%), pityriasis alba (9.9%), dermatophytosis (6.2%), viral dermatosis (6.2%), scabies (3.0%) and acne vulgaris (2.7%). The prevalence of angular stomatitis, miliaria rubra, candidiasis, piedra nigra, keratosis pilaris, ephelides and geographic tongue is lower but still relatively high. Females had higher rates of pediculosis capitis and males higher prevalence of pityriasis alba. The prevalence of pityriasis versicolor, pigmented nevus and scabies was similar in males and females. Folliculitis, macular pigmented nevi and especially pityriasis versicolor tended to increase with age. Leprosy is hyperendemic in the surveyed area and its rate in the schoolchildren examined was 0.08%. Population movement (urbanization), socioeconomic situation, living conditions, promiscuity, and lack of hygiene may be the cause of such high prevalence and of association of two or more skin conditions. Climatic conditions might have enhanced the prevalence of certain dermatoses (pityriasis versicolor, dermatophytosis, piedra nigra, candidiasis, miliaria rubra).

Proposed modifications to 1982 ACR classification criteria for systemic lupus erythematosus: serositis criterion.

The SLICC group believed that the definition of pleuritis should be expanded to include new pleural thickening and pericarditis to include characteristic history. Furthermore, SLICC suggested the addition of abdominal serositis to the current serositis criterion, manifested as either diffuse abdominal pain, with rebound or guarding, and/or ascites or bowel wall edema in the absence of other causes. Abdominal serositis can be secondary to either acute or chronic lupus peritonitis, with the former usually presenting as acute, generalized pain, and the latter as painless ascites.

Review of ACR renal criteria in systemic lupus erythematosus.

The American College of Rheumatology renal criteria require re-evaluation to incorporate recent advances in the classification of glomerulonephritidies. Renal biopsy is now common and safely performed by experienced nephrologists in community as well as academic settings. The optimal criterion is renal histopathology findings of an immune complex mediated glomerulonephritis as interpreted by an experienced pathologist employing accepted criteria. Renal biopsies should be analysed by routine histopathology, immunofluorescent and electron microscopy. Rating of activity and chronicity should be noted. Secondary criteria for patients unable to undergo renal biopsy includes a combination of findings. These include proteinuria, hypocomplementemia, elevated anti-dsDNA antibodies and an active urine sediment. Proteinuria is a nonspecific finding and, most importantly, can be associated with a number of comorbidities including diabetes, hypertension and atherosclerotic disease. Persistent proteinuria > 0.5 g per day or a spot protein to creatine ratio of > 0.5 should be accompanied by an additional feature supporting active lupus such as positive serologies (hypocomplementemia and/or elevated anti-dsDNA antibodies) and/or active urinary sediment. Similarly, active urinary sediment should be accompanied by the additional criterion of proteinuria to meet renal criteria. Decline in renal function is not a reliable criterion given the numerous medications, comorbidities and other clinical circumstances which may result in this feature.

ACR classification criteria for systemic lupus erythematosus: complement components.

Complement is involved in the pathogenesis of systemic lupus erythematosus (SLE) and has also a seemingly paradoxical protective role in the development of the disease. Low levels of components within the classical pathway of complement especially C1q, C4 and C3 have a high specificity for SLE diagnosis and should be considered as promising for inclusion in classification criteria of SLE.

Geriatric education across 94 million acres: adapting conference programming in a rural state.

Montana, a predominantly rural state, with a unique blend of geography and history, low population density, and cultural diversity represents the challenges for program development and implementation across remote areas. The paper discusses two statewide multidisciplinary geriatric education programs for health professionals offered by the recently established Montana Geriatric Education Center (MTGEC); use of telecommunications technology; collaborations with Geriatric Education Centers (GECs) and the Montana Healthcare Telemedicine Alliance (MHTA); and training outcomes, insights, and implications for continuing education of health professionals who practice in hard-to-reach regions. In addition, data from a statewide needs assessment are presented specific to preferred format. The MTGEC training model that combined traditional classroom and videoconference increased attendance by twofold and may be adapted in other regions to train providers in remote areas of the U.S.

[Psychiatric disorders in patients with diabetes type 2 at medical care and training district of Rio Branco-Acre, Brazil].

INTRODUCTION: Studies have established higher prevalence of psychiatric disorders in diabetic patients. OBJECTIVE: To describe the socio-demographic and clinic characteristics and to compare the frequency of them in the diabetic and non-diabetic populations. METHOD: Transversal study with comparing groups. Eighty four diabetic patients were compared with similar number of non-diabetic gathered with respect to gender, age and place of residency. RESULTS: Generalised Anxiety Disorder was frequent in both groups: 73.8% in diabetics and 65.5% in non-diabetics. The Phobic-Anxious Disorders represented 42.8% in diabetic group and 31.5% in non-diabetic. The rates of Mood Disorders were 53.5% in diabetics and 29.1% in non-diabetics, where only the categories Suicidal Risk (p=0.03) and Past Hypo-Maniac Episode (p=0.006) were of statistical significance for diabetics. CONCLUSION: anxiety and mood disorders were the most frequent, and predominant in diabetic patients.

[Acute Chagas cardiopathy. A systematic study of the intracardiac excitatory-conduction and autonomic nervous systems in an autochthonous case in Acre].

The histopathology of the heart is described in an acute case of Chagas' disease (DC). Lesions involving the conducting system (SC) and the autonomic intracardiac nervous system (SNAIC) are emphasized. Light microscopy showed acute pan-carditis with plenty of Trypanosoma cruzi amastigotes within heart muscle cells. Multiple inflammatory foci were found in the SC with parasitic nests within the atrioventricular node and left his bundle. There were also severe atrial periganglionitis and perineuritis with or without peripheral involvement of those structures. Apparently there was no cardiac neuronal depopulation. The epidemiological study suggested transmission through Rhodnius pictipes. To the best of our knowledge, this is the first reported case of acute DC from the Amazonian basin with systematized microscopy study of the SC and SNAIC.

The Acre Project: the epidemiology of malaria and arthropod-borne virus infections in a rural Amazonian population.

The authors describe the baseline malaria prevalence and arbovirus seroprevalence among 467 subjects in an ongoing cohort study in rural Amazonia. Most subjects (72.2%) reported one or more previous episodes of malaria, and 15.6% had been hospitalized for malaria, but only 3.6% of individuals five years or older had malaria parasites detected by microscopy (10 with Plasmodium vivax and 4 with P. falciparum). Antibodies to Alphavirus, Orthobunyavirus, and/or Flavivirus were detected by hemagglutination inhibition (HI) in 42.6% of subjects aged five years or older, with a higher seropositivity rate among males (49.2%) than females (36.2%). Since 98.9% of subjects had been immunized for yellow fever, the presence of cross-reactive antibodies to dengue and other Flaviviruses cannot be ruled out, but at least 12 subjects (3.3%) with IgM antibodies to dengue virus detected by ELISA had a putative recent exposure to this virus.
