Acidentes na infância atendidos no pronto socorro de pediatria do Hospital das Clínicas de Botucatu que motivaram internação

Accidents represent a major public health problem as they are frequent, preventable, and account for high morbidity and mortality rates. Children are the most vulnerable to accidents due to their inherent characteristics, and as a result of their physical, sensorial, psychomotor and cognitive limitations, which will only develop with time. Watchfulness and careful attention are of paramount importance, especially as children develop locomotor skills that are accompanied by curiosity about their surroundings. Child accidents, particularly those that could have been avoided, are the accidents most commonly seen in emergency and urgency departments. Urgency and emergency departments are the greatest allies in the attention to pediatric accidents as they offer adequate, immediate and specific high complexity care to patients at risk, viewing their vital stabilization. Investigating the causes and consequences of this insult is essential to establish a diagnosis and to contribute for the adoption of measures of prevention, control, and assistance. To identify the epidemiologic characteristics of the accidents involving children that received care at the pediatric emergency department of Botucatu Medical School Hospital and required hospitalization. This quantitative, retrospective, descriptiveanalytic epidemiologic study included all children aged 0-14 years who had had an accident and were seen at the Pediatric Emergency Department of Botucatu Medical School Hospital of São Paulo State University/UNESP between January 1/2008 and December 31/2009. A total of 227 medical charts were reviewed and 178 (78.4%) patients were included in this study. Of these, 116 (65.1%) were males and 62 (34.8%) were females. Children aged 5 - 9 years (38.9%) were the most affected, followed by those aged 10 - 14 years (37.5%). Fractures occurred in 138 (77.5%) of the cases, followed by foreign bodies...

Broncoscopia flexível como primeira opção para a remoção de corpo estranho das vias aéreas em adultos

OBJETIVO: Determinar a taxa de sucesso da broncoscopia flexível como primeira opção na remoção de corpos estranhos das vias aéreas em adultos. MÉTODOS: Estudo retrospectivo de todos os pacientes adultos (acima de 18 anos) com aspiração de corpo estranho submetidos a broncoscopia no Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo, em São Paulo (SP). RESULTADOS: A amostra foi constituída por 40 pacientes adultos, com média de idade de 52 anos (variação: 18-88 anos). A mediana do tempo de permanência do corpo estranho na via aérea foi de 15 dias (variação: 12 h a 10 anos). Todos os pacientes foram submetidos primeiramente a broncoscopia flexível diagnóstica. A retirada do corpo estranho por meio de broncoscopia flexível foi bem-sucedida em 33 dos pacientes (82,5%). Em 1 paciente, um objeto metálico alojado na árvore brônquica distal requereu o uso de fluoroscopia. Seis pacientes (15%) foram submetidos a broncoscopia rígida devido a dispneia induzida por corpo estranho traqueal, em 2, e porque o corpo estranho era muito grande para as pinças flexíveis, em 4. A broncoscopia falhou em apenas 1 paciente, que portanto necessitou de broncotomia. CONCLUSÕES: Embora a broncoscopia rígida seja considerada o padrão ouro na remoção de corpos estranhos na via aérea, nossa experiência mostrou que a broncoscopia flexível pode ser utilizada segura e eficientemente no diagnóstico e tratamento de pacientes adultos estáveis.

Influence of Helmet Use in Facial Trauma and Moderate Traumatic Brain Injury Victims of Motorcycle Accidents

Objective: The objective of this research was to study the influence of the use of helmet in facial trauma victims of motorcycle accidents with moderate traumatic brain injury. Methods: We retrospectively reviewed the incidence of facial injuries in helmeted and nonhelmeted victims with moderate traumatic brain injury at a referral trauma hospital. Results: The sample consisted of 272 patients predominantly men (94.5%) and between 21 and 40 years old (62.9%). The majority of patients were using helmet (80.1%). The occurrence of facial fractures was most frequent for zygomatic bone (51.8%), followed by mandible (18.8%) and nasal bones (9.2%). Conclusions: Individuals in the most productive age group are most affected, which causes a great loss to financial and labor systems. It is important to take measures to alert the public regarding the severity of injuries likely to occur in motorcycle-related accidents and ways to prevent them.

Dangerous waters: outbreak of eye lesions caused by fresh water sponge spicules

Purpose To describe an extremely uncommon outbreak of eye lesions in a specific area of the Brazilian Amazonia. Methods Prospective noncomparative case series. Fifty-nine patients who developed eye lesions after swimming in the Araguaia river of Tocantins state in Brazil were examined. A team of ophthalmologists equipped with a slit-lamp, gonioscopic lenses, and indirect ophthalmoscopy performed full eye examination. Analysis of the flora and fauna of the river water was undertaken by a group of experts. Results and Conclusions Eighty-three eyes were affected. The most common lesions were corneal opacities seen in 34 eyes and conjunctival nodules diagnosed in 12 eyes. Severe visual acuity loss was detected in seven children with unilateral anterior chamber lesions. Spicules of the sponge species Drulia uruguayensis and Drulia ctenosclera were found inside three blind eyes that have been enucleated for diagnostic purposes. All eye lesions could be attributed to an outbreak of foreign bodies from fresh water sponges. Organic enrichment of the water resulting from the absence of sanitation probably was the key factor, which initiated a cycle of ecological imbalance that provoked human disease.

Bacterial colonization and infection of electrophysiological cardiac devices detected with sonication and swab culture

Electrophysiological cardiac devices are increasingly used. The frequency of subclinical infection is unknown. We investigated all explanted devices using sonication, a method for detection of microbial biofilms on foreign bodies.

A review of full-body radiography in nontraumatic emergency medicine

This paper reports on the application of full-body radiography to nontraumatic emergency situations. The Lodox Statscan is an X-ray machine capable of imaging the entire body in 13 seconds using linear slit scanning radiography (LSSR). Nontraumatic emergency applications in ventriculoperitoneal (VP) shunt visualisation, emergency room arteriography (ERA), detection of foreign bodies, and paediatric emergency imaging are presented. Reports show that the fast, full-body, and low-dose scanning capabilities of the Lodox system make it well suited to these applications, with the same or better image quality, faster processing times, and lower dose to patients. In particular, the large format scans allowing visualisation of a greater area of anatomy make it well suited to VP shunt monitoring, ERA, and the detection of foreign bodies. Whilst more studies are required, it can be concluded that the Lodox Statscan has the potential for widespread use in these and other nontraumatic emergency radiology applications.

Injuries due to sharp trauma detected by post-mortem multislice computed tomography (MSCT): a feasibility study

Modern cross-sectional imaging techniques are being increasingly implemented in forensic pathology. In order to assess the practicability of such a method, namely post-mortem multislice computed tomography (MSCT) in cases of fatal cut and stab injuries, 12 corpses underwent such an examination prior to forensic autopsy. The questions regarding detection of foreign bodies, wound channels, skeletal and organ injuries, as well as the cause of death were addressed at MSCT and autopsy. The results of the two techniques revealed that post-mortem MSCT a useful tool in the assessment of such injuries.

Nail surgery

Nail surgery is a special branch of hand and dermatologic surgery. It is not widely performed, and many physicians do not feel at ease to perform it. The objective of this contribution is to give a short overview of the most important surgical procedures in clinical practice. References from the literature and the author's own experiences are condensed to describe what a dermatologic practitioner with knowledge of the nail and some surgical skills can perform. Nail surgery is a precise technique that requires careful administration and attention to details. Proper patient preparation starts with a patient history to identify potential contraindications and to prevent unnecessary complications. The author recommends isopropyl alcohol scrub and chlorhexidine for disinfection and ropivacaine 1% for anesthesia. The technique used for anesthesia depends on the type of surgery. Surgical procedures are described for diagnostic biopsies, nail avulsion in general, onychogryposis, paronychia treatment, hematomas and bone fracture due to trauma, removal of subungual foreign bodies, ingrowing nails, pincer nails, warts, ungual fibrokeratomas, digital myxoid pseudocyst, subungual exostoses, and various tumors. If performed correctly with adequate skills, nail surgery will lead to functionally and aesthetically satisfying results in the majority of instances.

Body weight estimation based on postmortem CT data-validation of a multiplication factor

Postmortem computed tomography (pmCT) is increasingly applied in forensic medicine as a documentation and diagnostic tool. The present study investigated if pmCT data can be used to estimate the corpse weight. In 50 forensic cases, pmCT examinations were performed prior to autopsy and the pmCT data were used to determine the body volume using an automated segmentation tool. PmCT was performed within 48 h postmortem. The body weights assessed prior to autopsy and the body volumes assessed using the pmCT data were used to calculate individual multiplication factors. The mean postmortem multiplication factor for the study cases was 1.07 g/ml. Using this factor, the body weight may be estimated retrospectively when necessary. Severe artifact causing foreign bodies within the corpses limit the use of pmCT data for body weight estimations.

Esophageal hiatal hernia in three exotic felines--Lynx lynx, Puma concolore, Panthera leo.

Hiatal hernia was diagnosed in three exotic felines-lynx (Lynx lynx), cougar (Puma concolore), and lion (Panthera leo). All cats had a history of anorexia. Thoracic and abdominal radiographs showed evidence of a soft tissue mass within the caudal mediastinum suggestive of a hiatal hernia in all animals. A barium esophagram was performed in one case. All animals underwent thoracic or abdominal surgery for hernia reduction. Surgical procedures included: intercostal thoracotomy with herniorrhaphy and esophagopexy (lynx and cougar), and incisional gastropexy (lion). Concurrent surgical procedures performed were gastrotomy for gastric foreign body removal and jejunostomy tube placement. Clinical signs related to the hiatal hernia disappeared after surgery and recurrence of signs was not reported for the time of follow-up.

Mortes por Asfixias com Alimentos em Crianças: Aspectos Médico Legais da Sufocação Direta por Engasgamento

The asphyxia by suffocation (choking) with foreign bodies are dramatic. Among these, the choking with food are responsible for most of these deaths. Children under four years old are particularly vulnerable due to not having a well-developed posterior dentition. The paper presents the report of two cases of suffocation with food and discusses some legal medical concepts, warning of the further prevention of such cases.

Anterior ophthalmic imaging

Improvements in imaging chips and computer processing power have brought major advances in imaging of the anterior eye. Digitally captured images can be visualised immediately and can be stored and retrieved easily. Anterior ocular imaging techniques using slitlamp biomicroscopy, corneal topography, confocal microscopy, optical coherence tomography (OCT), ultrasonic biomicroscopy, computerised tomography (CT) and magnetic resonance imaging (MRI) are reviewed. Conventional photographic imaging can be used to quantify corneal topography, corneal thickness and transparency, anterior chamber depth and lateral angle and crystalline lens position, curvature, thickness and transparency. Additionally, the effects of tumours, foreign bodies and trauma can be localised, the corneal layers can be examined and the tear film thickness assessed. © 2006 The Authors.
