Puncture wounds by driftwood catfish during bucket baths: Local habits of riverside people and fish natural history in the Amazon

Objective. - To assess the prevalence of stings by small spiny driftwood catfish (carataí) of the genus Centromochlus (Auchenipteridae) accidentally caught in buckets during bucket bathing by riverside people along the Brazilian Amazon and to determine the probability of catching specimens of these fish during random throws of a bucket into the river. Methods. - We interviewed 27 adult residents living at the confluence of the Negro and Solimões rivers in Brazil regarding whether or not they had ever been stung by driftwood catfish while bucket bathing. To assess the likelihood of catching catfish in bathing buckets, we randomly threw a typical plastic bucket used for bathing in 4 series of 10 throws into the river at dusk or night around a floating house. Results. - Seventeen of the 27 subjects (63%) reported being injured by driftwood catfish during bucket bathing. Three individuals (17.6%) had been injured 2 to 3 times, totaling 23 puncture accidents. All stings occurred at dusk or early night. In the 4 series of 10 bucket throws, we caught 3 driftwood catfish (in 1 series we did not catch any fish). Thus, the chance of catching a driftwood catfish in a single bucket throw at dusk was slightly less than 10%. Conclusions. - The prevalence of stings by driftwood catfish to people bucket bathing in this section of the Brazilian Amazon is high, partly because of the relatively high chances of catching these small catfish during random throws of a bathing bucket into the river.

Work and injuries in dancers: Survey of a professional dance company in Brazil

This study examined the daily life and most important physical injuries suffered and reported by the dancers of a professional (contemporary) dance company in S (a) over tilde $o Paulo, Brazil. Through an observational, cross,sectional, retrospective procedure using a questionnaire that collected qualitative and quantitative data, we were able to gather information on 30 dancers who collaborated with the survey. We determined that the injuries considered as most important by dancers were those that prevented dance activity during some months. These injuries occurred mainly during rehearsals (which is the activity occuppying, the most time on the schedule). Articular injuries were the most frequent and mainly involved the knee and ankle. They were related to classical technique, in which most of the company's artists started their dance careers. Medical care usually was sought within 1 day, and the prescribed treatment resolved the problem, but the injury cause was not identified in all cases.

Childhood trauma in substance use disorder and depression: An analysis by gender among a Brazilian clinical sample

Objective: In this study, we compared the frequency and intensity of childhood traumas in alcohol- or other drug-dependent patients, in patients with depression, and in a control group without psychiatric diagnoses. Methods: The study had a retrospective design of a clinical sample of men and women from the groups listed above. They were evaluated by the same standardized instrument: the Childhood Trauma Questionnaire.. Results: A higher frequency and intensity of emotional, physical, and sexual abuse were found in alcohol- and other drug-dependent patients than in patients with depression, who, in turn, presented significantly higher proportions than the control group. In all of the cases, the frequency was higher among women than men. Conclusion: Because of the high frequency and intensity of childhood traumas among alcohol- or other drug-dependent patients and depressed patients, the assessment of problems due to childhood traumas among these patients is essential to a better understanding of the etiology of those disorders and to their treatment. © 2010 Elsevier Ltd.

Infecções cutâneas e acidentes por animais traumatizantes e venenosos ocorridos em aquários comerciais e domésticos no Brasil: descrição de 18 casos e revisão do tema

FUNDAMENTOS: O aquarismo a cada dia ganha novos adeptos no Brasil. Impulsionado por belos peixes e objetos de decoração, o hábito pode trazer problemas como infecções e envenenamentos por diversos animais. OBJETIVOS: Demonstração dos animais causadores e dos quadros clínicos envolvidos com estes acidentes, das infecções cutâneas encontradas após traumas e das medidas terapêuticas e preventivas para controle do problema, pouco conhecido pela população em geral. MÉTODOS: Utilizou-se um estudo prospectivo para a detecção de acidentes por animais e infecções ocorridas após traumas em aquários. Estes dados serviram de base para um estudo epidemiológico, clínico e terapêutico sobre o problema. RESULTADOS: em cerca de 300 acidentes por animais aquáticos, 12 ou 4% do total foram causados por animais venenosos em aquários. Cinco infecções bacterianas e uma fúngica foram identificadas após traumas em aquários. CONCLUSÕES: Os acidentes em aquários domésticos e comerciais são relativamente comuns e podem acarretar infecções cutâneas e ferimentos por animais venenosos ou traumatizantes. Os proprietários de aquários na maioria das vezes não têm informações sobre estes acidentes. Os autores fornecem as espécies de microorganismos e animais mais freqüentemente envolvidas com ferimentos e as medidas terapêuticas e preventivas adequadas ao manejo do problema.

HIPERTERMIA EM RATOS INDUZIDA PELA LESAO ELETROLITICA DO MESENCEFALO: PARTICIPACAO DAS PROSTAGLANDINAS

The present studies were conducted to determine the role of prostaglandins in the etiology of a rise of body temperature observed in rats after electrolytic lesion made on the dorsal mesencephalic areas. This hyperthermia was abolished by intraperitoneal administration of indomethacin, an inhibitor of prostaglandins synthesis. These results strengthen the suggestion of a similar mechanism for both neurogenic hyperthermia and the fevers produced by pyrogens. However, until further experiments are carried out, the possibility of lesion in producing hyperthermia by different mechanisms cannot be ruled out.

Attack upon a bather by a swordfish: A case report

We report a case of a bather injured by a swordfish in shallow water off the coast of southern Brazil. The victim suffered multiple injuries from the fish's bill, including a puncture wound of his left knee and the tip of the bill remaining as a foreign body. The victim made a full recovery after field management and conservative care. The potential factors leading to this most unusual attack are discussed. © 2009 Wilderness Medical Society.

Occurrence of traumatic dental injury in cases of domestic violence

The purpose of this study was to investigate the prevalence and types of traumatic dental injuries in situations of domestic violence. A coross-sectional study was conducted and data were collected from the police occurrence records to domestic physical aggression between 2001 and 2005. Of the 1,844 subjects who underwent medical evaluation, 15 had information pertaining to traumatic dental injuries. From the medical records, the forensic medical reports completed by the forensic medical experts who examined the victims after the aggression were reviewed and data of individuals with dental injuries (e.g., fractures, luxation and avulsion) were collected. In the selected sample, there was a predominance of individuals with injuries to the head and neck region (38.7%), and the frequency of traumatic dental injuries among all injuries to the head and neck region was 2.0%. The most frequently injured teeth were the maxillary incisors (31.8%), followed by the mandibular incisors (27.3%) and the maxillary canines (9.1%). In 31.8% of the injured teeth, the forensic experts did not specify the nomenclature. Of the dental trauma cases, 59.1% were fractures, 27.2% were luxations and 13.7% were avulsions. In conclusion, domestic violence was an important etiologic factor of traumatic dental injury. The aggression in all cases occurred in the form of punches and slaps. Fracture was the most common type of traumatic dental injury, and the most frequently injured teeth were the incisors.

Avaliação dos parâmetros gasométricos dos traumatizados durante o atendimento pré-hospitalar móvel

OBJECTIVE: To evaluate gasometric differences of severe trauma patients requiring intubation in prehospital care. METHODS: Patients requiring airway management were submitted to collection of arterial blood samples at the beginning of pre-hospital care and at arrival at the Emergency Room. We analyzed: Glasgow Coma Scale, respiratory rate, arterial pH, arterial partial pressure of CO2 (PaCO2), arterial partial pressure of O2 (PaO2), base excess (BE), hemoglobin O2 saturation (SpO2) and the relation of PaO2 and inspired O2 (PaO2/FiO2). RESULTS: There was statistical significance of the mean differences between the data collected at the site of the accident and at the entrance of the ER as for respiratory rate (p = 0.0181), Glasgow Coma Scale (p = 0.0084), PaO2 (p <0.0001) and SpO2 (p = 0.0018). CONCLUSION: tracheal intubation changes the parameters PaO2 and SpO2. There was no difference in metabolic parameters (pH, bicarbonate and base excess). In the analysis of blood gas parameters between survivors and non-survivors there was statistical difference between PaO2, hemoglobin oxygen saturation and base excess.

Orientações de alta: cartões padronizados ajudam na compreensão dos pacientes do pronto socorro?

OBJECTIVE: To determine whether the addition of discharge standard illustrated cards improves understanding of patients in the emergency room. METHODS: We conducted a prospective, randomized, interventional study with 228 patients discharged from the emergency department. All patients were interviewed and tested for the level of understanding of discharge instructions. Some of them received the intervention, with the standard cards, and another did not, constituting the control group. RESULTS: The average of followed discharge guidelines of the group that received the cards was higher than the control group, with statistical significance (p=0.009). When segregated by age, the group between 16 and 35 years of both sexes had the best average of followed guidelines, statistically, than the average of the control group (p=0.01). The difference between the mean orientations between the control group and the card for patients undergoing procedures was statistically significant (p=0.02); as for the stratification according to the number of procedures, the significance increases when that is equal to 1 (p=0.001) and decreased the more procedures were carried out. CONCLUSION: The introduction of discharge standard orientation cards was associated with improvement in the understanding of patients. Without replacing the verbal directions, which establishes dialogue and doctor-patient bonding, cards appear as auxiliary elements, facilitating understanding and care guidelines.

A lei seca cumpriu sua meta em reduzir acidentes relacionados à ingestão excessiva de álcool?

OBJECTIVE: To assess whether the Brazilian Driving Dry Law reached its goal after the three years following its enactment. METHODS: We onnducted a retrospective study of patients with craniofacial fractures who underwent surgery at a university hospital in two periods: before the Law (2005 to 2008) and after the Law (2008 to 2011). RESULTS: 265 patients (220 men and 45 women) were operated on during this period, 149 (56%) before and 116 (44%) after the Law, which indicates a reduction in the number of traumatisms (p=0.04). The age range between 19 and 40 years predominated in both periods. The main causes of traumas were car accidents, physical aggression and falls. Alcohol abuse was identified in 15.4% patients before and 19% patients after the enactment. The jaw and the maxillo-zygomatic complex were the most affected bones. CONCLUSION: The drop in the number of polytraumatized patients operated on at this institution in the three years following the Driving Dry Law was 22%, which is below the expected and desired percentage. These results must be compared to those of different services offering the same attendance type in order to compile data and enlarge statistics. The low index of reduction in the number of traumatisms and the report of alcohol abuse by several patients at the moment of trauma, even after the law, evidence the need of adopting stricter measures to control and punish violators.
