RESUMEN

Introducción: el envenenamiento por mordedura de ofidios es reconocido como un problema de salud pública según la Organización Mundial de la Salud. La baja incidencia sumada a la diversidad de presentaciones clínicas, edades, topografías afectadas, así como los diferentes protocolos en la bibliografía existente sobre algunos aspectos del tratamiento, hacen difícil el manejo sistematizado de estos pacientes. El objetivo de este trabajo es realizar una revisión sistemática de la literatura sobre mordedura de serpientes en pacientes pediátricos con afectación en mano y miembro superior, haciendo hincapié en la conducta frente las complicaciones loco-regionales. Por importancia y frecuencia destacamos al síndrome compartimental, las flictenas y las infecciones. Metodología: se realizó una búsqueda bibliográfica en MedLine/PubMed con las palabras clave: "Snake Bite hand Children" y "Snake Bite compartimental syndrome". Se incluyeron los artículos publicados en los últimos 10 años (2012 al 2022). Resultados: la búsqueda de artículos ante las palabras "Snake Bite hand Children" resultó en 20 articulos y la busqueda ante las palabras "Snake Bite compartimental syndrome" derivó en 34. Luego de aplicar los criterios de inclusión y exclusión se obtuvieron 30 artículos para el análisis. Conclusiones: la población pediátrica se encuentra más expuesta a las mordeduras por serpientes y a su vez a presentar lesiones más severas. El tratamiento del síndrome compartimental continúa siendo un tema de debate. El veneno inoculado puede simular un síndrome compartimental que puede revertir sin fasciotomías con el tratamiento adecuado. Igualmente, ante síntomas y signos claros de síndrome compartimental se sugiere realizar fasciotomías frente a las graves secuelas potenciales. Ante la aparición de flictenas, el destechado cuidadoso de la misma es un tratamiento adecuado. La mayoría de los autores coinciden con el tratamiento profiláctico con antibioticoterapia.

Introduction: Ophidian bite poisoning is recognized as a public health problem by the World Health Organization. The low incidence added to the diversity of clinical presentations, ages, affected topographies, as well as the different protocols in the existing literature on some aspects of treatment, make the systematized management of these patients difficult. The aim of this work is to carry out a systematic review of the literature on snakebite in pediatric patients with hand and upper limb involvement, with emphasis on the management of loco-regional complications. In terms of importance and frequency, we highlight compartment syndrome, phlyctenas and infections. Methodology: a literature search was carried out in MedLine/PubMed with the keywords: "Snake Bite hand Children" and "Snake Bite compartment syndrome". Articles published in the last 10 years (2012 to 2022) were included. Results: the search for articles with the words "Snake Bite hand Children" resulted in 20 articles and the search for the words "Snake Bite compartment syndrome" resulted in 34 articles. After applying the inclusion and exclusion criteria, 30 articles were obtained for the analysis. Conclusions: the pediatric population is more exposed to snake bites and in turn to present more severe lesions. The treatment of compartment syndrome continues to be a subject of debate. Inoculated venom can simulate a compartment syndrome that can be reversed without fasciotomies with proper treatment. Likewise, in the presence of clear symptoms and signs of compartment syndrome, fasciotomies are suggested because of the serious sequelae generated. In the event of the appearance of phlyctenas, careful unroofing of the phlyctenas would be an appropriate treatment. Most authors agree with prophylactic treatment with antibiotic therapy.

Após a aplicação dos critérios de inclusão e exclusão, foram obtidos 30 artigos para análise. Conclusões: a população pediátrica está mais exposta às picadas de cobra e, por sua vez, a lesões mais graves. O tratamento da síndrome compartimental continua a ser motivo de debate. O veneno inoculado pode simular uma síndrome de compartimento que pode ser revertida sem fasciotomias com tratamento apropriado. Da mesma forma, se houver sinais e sintomas claros de síndrome compartimental, são sugeridas fasciotomias por causa das severas seqüelas. Se as flectenas aparecerem, o desenrolamento cuidadoso das flectenas seria um tratamento apropriado. A maioria dos autores concorda com o tratamento profilático com a antibioticoterapia.

RESUMEN

Abstract Objective To evaluate the epidemiologic profile, the time until care, and the type of conduct taken regarding patients who are victims of accidents with circular saws and their resulting injuries, and to make a comparison with the literature. Methods A cross-sectional descriptive study reviewing the medical records of patients cared for from April to December 2018, analyzing age, gender, injured side, affected fingers, month and time of the accident, type of injuries, procedures performed in the emergency room, time elapsed between trauma and admission to the operating room, and reapproach during hospitalization. Results A total of 54 male patients aged between 15 and 72 years were care for. The left side was more affected, and the most frequent type of lesion involved the thumb, which had to be amputated in many cases. In total, 23 patients underwent reimplantation, 3 of which were macroreimplantations. Regarding the time of trauma, 26 cases occurred between noon and 4 p.m., and the time elapsed between the accident and the admission to the operating room was ≥ 6 hours in 84% of the patients. Conclusion Circular saw lesions are predominantly severe, with a potential for leaving permanent sequelae, and they affect mainly the thumb. The characterization of the type of injury and the initial care conditions obtained in the present study may contribute to the policy of prevention and care of patients who are victims of circular saw injuries. Level of Evidence IV; Case Series.

RESUMEN

OBJECTIVES: Machinery injuries account for a substantial share of traumatic upper limb injuries (TULIs) affecting young active individuals. This study is based on the hypothesis that there is an important relationship between the improper use of power saws and TULIs. The aim of the study is to assess the prevalence and epidemiology of TULIs caused by power saws and determine the risks related to power saw use. METHODS: A cross-sectional evaluation of medical records from a two-year period was performed. Patients sustaining TULIs related to power saws were analyzed. Data on the epidemiology, site of injury, mechanism of trauma, technical specifications of the tool, cutting material, personal protective equipment, time lost and return to work were obtained. RESULTS: A database search retrieved 193 TULI records, of which 104 were related to power saws. The majority of patients were male (102/104; 98.1%), right-handed (97/104; 93.3%), and manual workers (46/104; 44.2%), with an average age of 46.8 years. The thumb was the most frequently injured site (32/93; 34.4%). Most of the injuries were caused by manual saws (85/104; 81.7%), and masonry saws accounted for 68.2% (58/85) of the cases. Masonry saws improperly used for woodwork resulted in 86.2% (50/58) of the injuries. TULI caused by masonry saws was 5 times higher in manual workers than in other patients. In addition, masonry saws had a risk of kickback 15 times higher than that of other saws, and the risk of injury increased by 5.25 times when the saws were used improperly for wood cutting. CONCLUSIONS: The profile of TULIs related to power saws was demonstrated and was mainly associated with manual saws operated by manual workers that inappropriately used masonry saws for woodworking.

RESUMEN

Snakebites by aglyphous or opisthoglyphous snakes are common in Brazil. We report a case of snakebite by the opisthoglyphous Erythrolamprus aesculapii. The victim presented with pain, edema, and bleeding at the bite site, along with erythema, similar to a Bothrops envenomation. In this type of snakebite, if the snake is not brought to the hospital, the victim may receive unnecessary serum therapy, with the risk of adverse reactions to the antivenom. The possibility of reducing after-effects with anti-inflammatory drugs and early antibiotic therapy for secondary infection need to be further investigated, preferably in multicenter studies, while observing good clinical practice.

RESUMEN

This is a case report of a bite by an Opisthoglyphous snake Thamnodynastes pallidus (Linnaeus, 1758) in an undergraduate herpetologist observed at the Universidade Federal da Paraiba (Rio Tinto, PB, Brazil). The female victim was bitten in her left hand between the index finger and the middle finger and presented symptoms of local envenomation such as bleeding, itching, pain in the wound and swelling. The patient was first seen at the University and afterwards at home during the 36 hours following the incident, when the symptoms disappeared. This is the first case report of an accident by T. pallidus in a human being in Brazil.

RESUMEN

BACKGROUND: Acute upper extremity injuries remain one of the most common consultations in the emergency departments for plastic surgery services. These injuries can affect a person's quality of life and negatively affect work-related or social interactions if not properly managed. We aim to evaluate our experience and management in a specialized referral center in Mexico City. METHODS: A retrospective review was performed. All patients with hand trauma managed by our service from July 2010 to June 2015 were included; their demographic characteristics were described as well as the most common patterns of injury, management, and outcome. RESULTS: A total of 4751 patients with injuries in the upper extremities were included, 77% were males with a mean age of presentation of 26.9 ± 17.9 years; the age group most commonly affected was between 16 to 30 years (39%); 54% of the cases affected the right hand. Lacerative wounds were the most common mechanism of injury (60.7%), followed by blunt trauma (28.7%). Management was surgical in 87% of the cases. CONCLUSIONS: Upper extremity trauma encompasses a wide range of clinical presentations, from simple lacerations to catastrophic injuries that require extensive or multiple reconstructive procedures. The clear understanding of the trauma mechanisms and how they are related with certain patterns of injury might maximize awareness and guide a surgeon's management effectively.

RESUMEN

Several interleukin 6 gene (IL6) polymorphisms are implicated in susceptibility to rheumatoid arthritis (RA). It has not yet been established with certainty if these polymorphisms are associated with the severe radiographic damage observed in some RA patients, particularly those with the development of joint bone ankylosis (JBA). The objective of the present study was to evaluate the association between severe radiographic damage in hands and the -174G/C and -572G/C IL6 polymorphisms in Mexican Mestizo people with RA. Mestizo adults with RA and long disease duration (>5 years) were classified into two groups according to the radiographic damage in their hands: a) severe radiographic damage (JBA and/or joint bone subluxations) and b) mild or moderate radiographic damage. We compared the differences in genotype and allele frequencies of -174G/C and -572G/C IL6 polymorphisms (genotyped using polymerase chain reaction-restriction fragment length polymorphism) between these two groups. Our findings indicated that the -174G/C polymorphism of IL6 is associated with severe joint radiographic damage [maximum likelihood odds ratios (MLE_OR): 8.03; 95%CI 1.22-187.06; P = 0.03], whereas the -572G/C polymorphism of IL6 exhibited no such association (MLE_OR: 1.5; 95%CI 0.52-4.5; P = 0.44). Higher anti-cyclic citrullinated peptide antibody levels were associated with more severe joint radiographic damage (P = 0.04). We conclude that there is a relevant association between the -174G/C IL6 polymorphism and severe radiographic damage. Future studies in other populations are required to confirm our findings.

RESUMEN

According to the International Atomic Energy Agency (IAEA), a relatively significant number of radiological accidents have occurred in recent years mainly because of the practices referred to as potentially high-risk activities, such as radiotherapy, large irradiators and industrial radiography, especially in gammagraphy assays. In some instances, severe injuries have occurred in exposed persons due to high radiation doses. In industrial radiography, 80 cases involving a total of 120 radiation workers, 110 members of the public including 12 deaths have been recorded up to 2014. Radiological accidents in industrial practices in Brazil have mainly resulted in development of cutaneous radiation syndrome (CRS) in hands and fingers. Brazilian data include 5 serious cases related to industrial gammagraphy, affecting 7 radiation workers and 19 members of the public; however, none of them were fatal. Some methods of reconstructive dosimetry have been used to estimate the radiation dose to assist in prescribing medical treatment. The type and development of cutaneous manifestations in the exposed areas of a person is the first achievable gross dose estimation. This review article presents the state-of-the-art reconstructive dosimetry methods enabling estimation of local radiation doses and provides guidelines for medical handling of the exposed individuals. The review also presents the Chilean and Brazilian radiological accident cases to highlight the importance of reconstructive dosimetry.

RESUMEN

Every year 10 to 20 cases of snake bites are reported on the Caribbean island of Martinique. The only snake involved, Bothrops lanceolatus, is endemic on the island, and its bite may lead to systemic multifocal thrombotic complications in the'absence of the monospecific antivenom. Between January 1988 and January 2009, more than 250 snake bites have been reported, and five patients were treated with hyperbaric oxygen (HBO2) therapy for local complications. The patients were male, bitten on the leg or the hand, and presented with severe complications such as necrotizing soft tissue infections, compartment syndrome or abscesses despite prompt wound care and administration of antivenomous serum. Outcomes were favorable for these five patients, except for one who was left with a functional defect of the hand. Although snake bites are not part of the currently recommended indications for HBO2 therapy, local complications, namely compartment syndrome, necrotizing soft tissue infections and enhancement of healing in selected problem wounds, are approved uses of HBO2 therapy as defined by the Hyperbaric Oxygen Therapy Committee and would benefit from prospective studies.

RESUMEN

High-voltage electric injuries have many manifestations, and an important complication is the damage of the central/peripheral nervous system. The purpose of this work was to assess the upper limb dysfunction in patients injured by high-voltage current. The evaluation consisted of analysis of patients' records, cutaneous-sensibility threshold, handgrip and pinch strength and a specific questionnaire about upper limb dysfunctions (DASH) in 18 subjects. All subjects were men; the average age at the time of the injury was 38 years. Of these, 72% changed job/retired after the injury. The current entrance was the hand in 94% and grounding in the lower limb in 78%. The average burned surface area (BSA) was 8.6%. The handgrip strength of the injured limb was reduced (p<0.05) and so also that of the three pinch types. The relationship between the handgrip strength and the DASH was statistically significant (p<0.001) as well as the relationship between the three pinch types (p

RESUMEN

Injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in humans. The phylum Echinoderma include more than 6000 species of starfish, sea urchins, sand dollars, and sea cucumbers some of which have been found responsible for injuries to humans. Initial injuries by sea urchins are associated with trauma and envenomation, but later effects can be observed. Sea urchin granuloma is a chronic granulomatous skin disease caused by frequent and successive penetration of sea urchin spines which have not been removed from wounds. The authors report a typical case of sea urchin granuloma in a fisherman and its therapeutic implications.
