Objetivo: Determinar a prevalência da automedicação em crianças e adolescentes dos municípios de Limeira e Piracicaba (SP), correlacionando-a a indicadores sociodemográficos e utilização de serviços de saúde (pública ou privada).Métodos: Estudo descritivo tipo inquérito populacional domiciliar de uma amostra aleatória simples de ambos os municípios, constituída de 772 moradores procedentes de 85 setores censitários selecionados por meio de amostragem por conglomerado. Critérios de inclusão: idade ≤ 18 anos; entrevista obrigatória com um dos responsáveis legais; ter consumido pelo menos um medicamento nos 15 dias prévios à data da entrevista. Segundo a orientação de uso de medicamentos, os participantes foram divididos em dois grupos de estudo: automedicação (orientação leiga) e prescrição médica. Foram realizados testes de associação linear, análise descritiva das variáveis e regressão logística múltipla. Resultados:A prevalência da automedicação foi de 56,6%. Os principais responsáveis e indutores da automedicação foram as mães (51%) e funcionários de farmácia (20,1%). Os principais grupos de medicamentos administrados na automedicação foram: analgésicos/antipiréticos e antiinflamatórios não-hormonais (52,9%); medicações de ação nos tratos respiratório (15,4%) e gastrointestinal (9,6%); e antibióticos sistêmicos (8,6%). As situações que mais motivaram a automedicação foram afecções respiratórias (17,2%), febre (15%) e cefaléia (14%). Indivíduos na faixa etária de 7-18 anos (razão de chances = 2,81) e usuários de serviços públicos de saúde (razão de chances = 1,52) apresentaram risco aumentado de automedicação. Conclusões:A prevalência da automedicação em crianças e adolescentes foi alta, reforçando a necessidade de intervenção das autoridades de saúde na prevenção desses agravos. Results:The prevalence of self-medication was 56.6%. Mothers (51%) and drugstore employees (20.1%) were most frequently responsible for self-medication. The main groups of self-prescribed drugs were: analgesic/antipyretic and non-hormonal antiinflammatory drugs (52.9%); drugs acting on the respiratory tract (15.4%) and gastrointestinal drugs (9.6%); and systemic antibiotics (8.6%). The situation that most commonly motivated selfmedication were respiratory diseases (17.2%), fever (15%), and headache (14%). Subjects in the age group of 7-18 years (odds ratio = 2.81) and public health care users (odds ratio = 1.52) showed increased risk for self-medication. Conclusions:The prevalence of self-medication in children and adolescents was high, which reinforces the need for public health interventions aiming at preventing this practice.J Pediatr (Rio J). 2007;83(5):453-458: Children, adolescents, drugs, self-medication, pharmacoepidemiology.
From January, 1984 to December, 1996, 422 patients (ages 9 m-99 y, median 29 y) were admitted after being bitten by spiders which were brought and identified as Phoneutria spp. Most of the bites occurred at March and April months (29.2%), in the houses (54.5%), during the day (76.5%), and in the limbs (feet 40.9%, hands 34.3%). Upon hospital admission, most patients presented only local complaints, mainly pain (92.1%) and edema (33.1%) and were classified as presenting mild (89.8%), moderate (8.5%) and severe (0.5%) envenomation. Few patients (1.2%) did not present signs of envenomation. Severe accidents were only confirmed in two children (9 m, 3 y). Both developed acute pulmonary edema, and the older died 9 h after the accident. Patients more than 70 year-old had a significantly greater (p<0.05) frequency of moderate envenomations compared to the 10-70-year-old individuals. Proceedings to relief local pain were frequently performed (local anesthesia alone 32.0%, local anesthesia plus analgesics 20.6% and oral analgesics alone 25. 1%). Only 2.3% of the patients (two cases classified as severe and eight as moderate, eight of them in children) were treated with i.v. antiarachnid antivenom. No antivenom early reaction was observed. In conclusion, accidents involving the genus Phoneutria are common in the region of Campinas, with the highest risk groups being children under 10 years of age and adults over 70 years of age. Cases of serious envenomation are rare (0.5%).
SUMMARY From February, 1981 to May, 2001, 63 children under 15 y old (ages 2 -15 y, median = 8 y, mean ± 1 SD = 8 ± 3 y) presenting 70 episodes of Paracoccidioidomycosis were admitted. The main clinical manifestations and laboratory features observed upon admission were: lymph node enlargement (87.1%), fever (75.7%), weakness (48.6%), pallor (41.4%), hepatomegaly (40%), splenomegaly (35.7%), anemia (90%), hypergammaglobulinemia (88.5%), eosinophilia (75.5%) and hypoalbuminemia (72.5%). Moderate to severe malnutrition was detected in 35.7% of the episodes (Gomez's criterion). Radiographic and technetium studies showed bone lesions in 20 of the episodes, most of them being multiple lytic lesions, involving both long (70%) and plain bones (30%). First line treatment consisted of an association of sulfametoxazole-trimethoprin, which was used, exclusively, in 50 episodes. Follow-up of hemoglobin levels, number of eosinophils in the peripheral blood, albumin and gammaglobulin serum levels revealed significant sequential improvement one and six months after hospital admission, being quite useful to evaluate treatment effectiveness. Six patients died (9.3%) and four developed sequelae (6.3%) . In conclusion, the juvenile and disseminated forms can be observed in about 70% of the episodes of PCM occurring in children younger than 15 y old, most of them presenting with a febrile lymphoproliferative syndrome associated to anemia, eosinophilia and hypergammaglobulinemia.
From January 1984 to May 1994, 17 of 239 children under 15 years old stung by Tityus serrulatus (15.1%) or Tityus bahiensis (84.9%) presented severe envenoming. Of these 17 patients (1-11 years old; median = 2 yr) 14 were stung by T. serrulatus and three by T. bahiensis. All of them received scorpion antivenom i.v. at times ranging from 45 min. to 5 h after the accident (median = 2 h). On admission, the main clinical manifestations and laboratory and electrocardiographic changes were: vomiting (17), diaphoresis (15), tachycardia (14), prostration (10), tachypnea (8), arterial hypertension (7), arterial hypotension (5), tremors (5), hypothermia (4), hyperglycemia (17), leukocytosis (16/16), hypokalemia (13/17), increased CK-MB enzyme activity (> 6% of the total CK, 11/12), hyperamylasemia (11/14), sinusal tachycardia (16/17) and a myocardial infarction-like pattern (11/17). Six patients stung by T. serrulatus had depressed left ventricular systolic function assessed by means of echocardiography. Of these, five presented pulmonary edema and four had shock. A child aged two-years old presented severe respiratory failure and died 65 h after being stung by T. serrulatus. Severe envenomations caused by T. serrulatus were 26.2 times more frequent than those caused by T. bahiensis (p < 0.001).
From January, 1984 to March, 1999, 31 children under 15 y old (ages 1-14 y, median 8 y) were admitted after being bitten by rattlesnakes (Crotalus durissus ssp). One patient was classified as "dry-bite", 3 as mild envenoming, 9 as moderate envenoming and 18 as severe envenoming. Most patients had neuromuscular manifestations, such as palpebral ptosis (27/31), myalgia (23/31) and weakness (20/31). Laboratory tests suggesting rhabdomyolysis included an increase in total blood creatine kinase (CK, 28/29) and lactate dehydrogenase (LDH, 25/25) levels and myoglobinuria (14/15). The main local signs and symptoms were slight edema (20/31) and erythema (19/31). Before antivenom (AV) administration, blood coagulation disorders were observed in 20/25 children that received AV only at our hospital (incoagulable blood in 17/25). AV early reactions were observed in 20 of these 25 cases (9/9 patients not pretreated and 11/16 patients pretreated with hydrocortisone and histamine H1 and H2 antagonists). There were no significant differences in the frequency of patients with AV early reactions between the groups that were and were not pretreated (Fisher's exact test, p = 0.12). Patients admitted less than and more than 6 h after the bite showed the same risk of developing severe envenoming (Fisher's exact test, p = 1). No children of the first group (< 6 h) showed severe complications whereas 3/6 children admitted more than 6 h post-bite developed acute renal failure. Patients bitten in the legs had a higher risk of developing severe envenoming (Fisher's exact test, p = 0.04). There was a significant association between both total CK and LDH blood enzyme levels and severity (p < 0.001 for CK and p < 0.001 for LDH; Mann-Whitney U test). No deaths were recorded.
Most coral snake bites reported in Brazil were caused by M. corallinus and M. frontalis, with several patients showing signs of acute myasthenia. Serious complications such as paralysis with respiratory failure were observed but comparatively rare. The deaths occurred where respiratory support (mechanical ventilation) was unavailable when needed.
From January, 1984 to March, 1999, 73 children under 15 y old (ages 1-14 y, median 9 y) were admitted after being bitten by snakes of the genus Bothrops. Twenty-six percent of the children were classified as mild envenoming, 50.7% as moderate envenoming and 20.6% as severe envenoming. Two patients (2.7%) showed no signs of envenoming. Most of the patients presented local manifestations, mainly edema (94.5%), pain (94.5%) ecchymosis (73.9%) and blisters (11%). Local and/or systemic bleeding was observed in 28.8% of the patients. Before antivenom (AV) administration, blood coagulation disorders were observed in 60.7% (incoagulable blood in 39.3%) of the 56 children that received AV only in our hospital. AV early reactions, most of which were considered mild, were observed in 44.6% of these cases (in 15/30 patients not pretreated and in 10/26 patients pretreated with hydrocortisone and histamine H1 and H2 antagonists). The main clinical complications observed were local infection (15.1%), compartment syndrome (4.1%), gangrene (1.4%) and acute renal failure (1.4%). No deaths were recorded. There were no significant differences with regard to severity of envenoming versus the frequency of blood coagulation disorders among the three categories of envenoming (p = 0.75) or in the frequency of patients with AV early reactions between the groups that were and were not pretreated (p = 0.55). The frequency of local infection was significantly greater in severe cases (p < 0.001). Patients admitted more than 6 h after the bite had a higher risk of developing severe envenoming (p = 0.04).
