Scabies: a clinical update.

Scabies is the most common neglected tropical disease with cutaneous manifestations, disproportionately affecting socially disadvantaged populations living in overcrowded settings. Scabies infestation is characterised by a generalised intractable pruritus, and is often complicated by secondary bacterial infection, which can lead to a range of complications. Scabies is a clinical diagnosis and requires an adequate degree of suspicion. The use of dermoscopy may improve diagnostic accuracy. In Australia, the first-line treatment recommended for scabies is topical permethrin 5% cream, applied to the whole body and repeated in one week. Oral ivermectin is subsidised by the Pharmaceutical Benefits Scheme with streamlined authority for patients who have completed and failed treatment with topical therapy, have a contraindication to topical treatment or have crusted scabies. Early identification and prompt initiation of treatment is key to minimise the disease burden of scabies.

Increasing the uptake of Intermittent Preventive Treatment of malaria in pregnancy using Sulfadoxine-Pyrimethamine (IPTp-SP) through seasonal malaria chemoprevention channel delivery: protocol of a multicenter cluster randomized implementation trial in Mali and Burkina Faso.

BACKGROUND: The uptake of Intermittent Preventive Treatment of malaria in pregnancy using Sulfadoxine-Pyrimethamine (IPTp-SP) remains unacceptably low, with more than two-thirds of pregnant women in sub-Saharan Africa still not accessing the three or more doses recommended by the World Health Organisation (WHO). In contrast, the coverage of Seasonal Malaria Chemoprevention (SMC), a more recent strategy recommended by the WHO for malaria prevention in children under five years living in Sahelian countries with seasonal transmission, including Mali and Burkina-Faso, is high (up to 90%). We hypothesized that IPTp-SP delivery to pregnant women through SMC alongside antenatal care (ANC) will increase IPTp-SP coverage, boost ANC attendance, and increase public health impact. This protocol describes the approach to assess acceptability, feasibility, effectiveness, and cost-effectiveness of the integrated strategy. METHODS AND ANALYSIS: This is a multicentre, cluster-randomized, implementation trial of IPTp-SP delivery through ANC + SMC vs ANC alone in 40 health facilities and their catchment populations (20 clusters per arm). The intervention will consist of monthly administration of IPTp-SP through four monthly rounds of SMC during the malaria transmission season (July to October), for two consecutive years. Effectiveness of the strategy to increase coverage of three or more doses of IPTp-SP (IPTp3 +) will be assessed using household surveys and ANC exit interviews. Statistical analysis of IPT3 + and four or more ANC uptake will use a generalized linear mixed model. Feasibility and acceptability will be assessed through in-depth interviews and focus group discussions with health workers, pregnant women, and women with a child < 12 months. DISCUSSION: This multicentre cluster randomized implementation trial powered to detect a 45% and 22% increase in IPTp-SP3 + uptake in Mali and Burkina-Faso, respectively, will generate evidence on the feasibility, acceptability, effectiveness, and cost-effectiveness of IPTp-SP delivered through the ANC + SMC channel. The intervention is designed to facilitate scalability and translation into policy by leveraging existing resources, while strengthening local capacities in research, health, and community institutions. Findings will inform the local national malaria control policies. TRIAL REGISTRATION: Retrospectively registered on August 11th, 2022; registration # PACTR202208844472053.

Experience of dermatologic biologic therapy use and associated opportunistic infection management in Australia's tropical north.

BACKGROUND/OBJECTIVES: Royal Darwin Hospital (RDH) is the sole public dermatology service in the Northern Territory (NT). Prescription of biologic therapies (BT) in the NT is uniquely challenging, with remote populations carrying a high tropical disease burden. The aim of this audit is to examine the demographics and outcomes of patients on BT for dermatologic conditions. METHODS: Retrospective case note review of patients receiving BT through the RDH Dermatology department between August 2021 and October 2023. Data analysed were demographics, location, dermatological diagnosis and serology status. RESULTS: In this audit, 115 patients were included. Age range of 13-91 years, mean of 51.1 years (±14.7), 52 (45.2%) patients were female and 8 (7.8%) identified as First Nations Australian. A large geographical area was serviced, with a primary address between 1 and 1496 km from RDH. Eighteen patients (15.7%) have discontinued BT completely. There was a statistically significant relationship between cessation of BT and increased distance of primary residence from RDH (p < 0.0007). Eighteen patients (15.7%) required management of infections identified in opportunistic infection screening. These infections were strongyloidiasis, tuberculosis, melioidosis and hepatitis B. CONCLUSIONS: There is significant anxiety surrounding BT and tropical infections, including in returning travellers in southern Australian states. There has been particular interest in strongyloidiasis infection, as dupilumab acts on the Th2 immunity mechanism critical to parasitic infection response. This audit exhibits the unique experience of dermatological care in a tropical setting, demonstrating how BT can be used safely and how, when identified, these tropical infections can be successfully managed.

Preclinical testing of expired antivenoms and its uses in real-world experience: a systematic review.

INTRODUCTION: Limited access to antivenoms is a global challenge in treating snakebite envenoming. In emergency situations where non-expired antivenoms are not readily available, expired antivenoms may be used to save lives with the risk of deteriorating quality, efficacy and safety. Therefore, we aimed to systematically review and summarise the sparse preclinical evidence of neutralising efficacy of expired antivenoms and real-world experience of using expired antivenoms in humans. METHODS: We searched for articles published until 1 March 2023 in PubMed, Scopus, Web of Science and Embase. Studies demonstrating the preclinical studies evaluating expired antivenoms or studies describing the real-world experience of using expired antivenoms were included. Narrative synthesis was applied to summarise the evidence of expired antivenoms. RESULTS: Fifteen studies were included. Ten were preclinical studies and five were real-world experiences of using expired antivenoms in humans. The expired duration of antivenoms in the included studies ranged from 2 months to 20 years. The quality of expired antivenoms was evaluated in one study, and they met the standard quality tests. Five studies demonstrated that the expired antivenoms' immunological concentration and venom-binding activity were comparable to non-expired ones but could gradually deteriorate after expiration. Studies consistently exhibited that expired antivenoms, compared with non-expired antivenoms, were effective when stored in proper storage conditions. The safety profile of using expired antivenoms was reported in two included studies. However, it was inconclusive due to limited information. CONCLUSION: Even though the quality and efficacy of expired antivenoms are comparable to non-expired antivenoms in preclinical studies, the information is limited in terms of real-world experiences of using expired antivenoms and their safety. Therefore, the use of expired antivenoms may be generally inconclusive due to scarce data. Further investigations may be needed to support the extension of antivenoms' expiration date according to their potential efficacy after expiration.

Scoring systems for prediction of malaria and dengue fever in non-endemic areas among travellers arriving from tropical and subtropical areas.

BACKGROUND: Fever is a common symptom among travellers returning from tropical/subtropical areas to Europe, and promptly distinguishing severe illnesses from self-limiting febrile syndromes is important but can be challenging due to non-specific clinical presentation. METHODS: A cross-sectional study enrolled adults and children who sought care during 2015-2020 at Karolinska University Hospital, Stockholm, Sweden with fever within 2 months after returning from travel to a tropical/subtropical area. Data on symptoms and laboratory parameters were prospectively and retrospectively collected. Two separate scoring systems for malaria and dengue were developed based on backward elimination regressions. RESULTS: In total, 2113 adults (18-94 years) and 202 children (1-17 years) were included, with 112 (4.8%) confirmed malaria by blood thick smear and 90 (3.9%) PCR/serology dengue-positive cases. Malaria was more likely in a patient who had visited sub-Saharan Africa and presented with combination of thrombocytopenia, anaemia and fever ≥39.5°C. Leucopenia, muscle pain and rash after travelling to Asia or South/Latin America indicated high probability of dengue. Two scoring systems with points between 0 and 7 for prediction of malaria or dengue were created based on the above predictors. Scores ≥3 indicated >80% sensitivity and specificity for malaria and >90% specificity for dengue in children and adults (area under the curve (AUC) for dengue: 0.92 in adults (95% CI 0.90 to 0.95) and 0.95 in children (95% CI 0.88 to 1.0); AUC for malaria: 0.93 in adults (95% CI 0.91 to 0.96) and 0.88 in children (95% CI 0.78 to 0.99)). Internal validation of optimism and overfitting was managed with bootstrap. CONCLUSION: The presented scoring systems provide novel tools for structured assessment of patients with tropical fever in a non-endemic area and highlight clinical signs associated with a potential severe aetiology to direct the need for microbial investigation.

Tropical Diseases in Okinawa: Overview and Emerging Infectious Diseases.

Okinawa prefecture is at risk for emerging infectious diseases due to its subtropical climate and its location within the Indo-Pacific region. Understanding the existing vectors and infectious agents contextualizes current threats, guides treatment, and informs prevention, and may be of unique concern in the setting of complex emergencies.

The Pathology of the Brain Eating Amoeba Naegleria fowleri.

The genus Naegleria is a taxonomic subfamily consisting of 47 free-living amoebae. The genus can be found in warm aqueous or soil habitats worldwide. The species Naegleria fowleri is probably the best-known species of this genus. As a facultative parasite, the protist is not dependent on hosts to complete its life cycle. However, it can infect humans by entering the nose during water contact, such as swimming, and travel along the olfactory nerve to the brain. There it causes a purulent meningitis (primary amoebic meningoencephalitis or PAME). Symptoms are severe and death usually occurs within the first week. PAME is a frightening infectious disease for which there is neither a proven cure nor a vaccine. In order to contain the disease and give patients any chance to survival, action must be taken quickly. A rapid diagnosis is therefore crucial. PAME is diagnosed by the detection of amoebae in the liquor and later in the cerebrospinal fluid. For this purpose, CSF samples are cultured and stained and finally examined microscopically. Molecular techniques such as PCR or ELISA support the microscopic analysis and secure the diagnosis.

Clinical Manifestations and Genomic Evaluation of Melioidosis Outbreak among Children after Sporting Event, Australia.

Melioidosis, caused by the environmental gram-negative bacterium Burkholderia pseudomallei, usually develops in adults with predisposing conditions and in Australia more commonly occurs during the monsoonal wet season. We report an outbreak of 7 cases of melioidosis in immunocompetent children in Australia. All the children had participated in a single-day sporting event during the dry season in a tropical region of Australia, and all had limited cutaneous disease. All case-patients had an adverse reaction to oral trimethoprim/sulfamethoxazole treatment, necessitating its discontinuation. We describe the clinical features, environmental sampling, genomic epidemiologic investigation, and public health response to the outbreak. Management of this outbreak shows the potential benefits of making melioidosis a notifiable disease. The approach used could also be used as a framework for similar outbreaks in the future.

The aetiology and incidence of infective endocarditis in people living with rheumatic heart disease in tropical Australia.

PURPOSE: To define the incidence and microbiological aetiology of infective endocarditis (IE) in patients with rheumatic heart disease (RHD) in tropical Australia. METHODS: A retrospective study that examined all episodes of IE between January 1998 and June 2021 among individuals on the RHD register in Far North Queensland, Australia. RESULTS: There were 1135 individuals with a diagnosis of RHD on the register during the study period, representing 10962 patient-years at risk. Overall, there were 18 episodes of definite IE occurring in 16 individuals, although only 7 episodes occurred in native valves (11 occurred in prosthetic valves) equating to 0.7 episodes of native valve IE/1000 patient-years. No patient with mild RHD - and only one child with RHD - developed IE during the study period. Despite the study's tropical location, the causative organism was usually typical skin or oral flora. Among individuals with an indication for benzathine penicillin G (BPG) prophylaxis, only 1/6 episodes of IE due to a penicillin-susceptible organism received BPG in the month before presentation. CONCLUSION: Although RHD predisposes individuals to IE, the absolute risk of IE in native valve disease in tropical Australia is low and might be reduced further by improved adherence to secondary BPG prophylaxis.

Transplantation and immigration: Comparing infectious complications and outcomes between foreign-born and US-born kidney transplant recipients in Minnesota.

BACKGROUND: Foreign-born kidney transplant recipients (FBKTRs) are at increased risk for reactivation of latent infections that may impact outcomes. We aimed to compare the etiology of infections and outcomes between FBKTR and United States KTRs (USKTR). METHODS: We performed a retrospective study of patients who underwent kidney transplantation between January 1, 2014 and December 31, 2018 at two transplant centers in Minnesota. Frequency and etiology of infections as well as outcomes (graft function, rejection, and patient survival) at 1-year post-transplant between FBKTR and USKTR were compared. RESULTS: Of the 573 transplant recipients, 124 (21.6%) were foreign-born and 449 (78.4%) US-born. At least one infection occurred in 411 (71.7%) patients (38.2% bacterial, 55% viral, 9.4% fungal). Viral infections were more frequent in FBKTR, particularly BK viremia (38.7% vs. 21.2%, p < .001). No statistical differences were found for bacterial or fungal infections; no parasitic infections were identified in either group. No geographically-restricted infections were noted aside from a single case of Madura foot in a FBKTR. Rejection episodes were more common in USKTR (p = .037), but stable/improving graft function (p = .976) and mortality (p = .451) at 1-year posttransplantation were similar in both groups. After adjusting for covariates, previous transplantation was associated with a higher number of infections (IRR 1.35, 95% confidence intervals 1.05-1.73, p = .020). CONCLUSION: Although viral infections were more frequent in FBKTR, overall frequency and etiology of most infections and outcomes were similar between FBKTR and USKTR suggesting that comprehensive transplant care is providing timely prevention, diagnosis, and treatment of latent infections in FBKTR.

Opsoclonus-myoclonus syndrome caused by organophosphate poisoning.

Opsoclonus-myoclonus syndrome is a combination of involuntary, arrhythmic, conjugate saccadic eye movements with myoclonus. The most common cause in adults is paraneoplastic encephalitis. Rarer causes include infections such as scrub typhus, and toxins such as organophosphates and cocaine. Organophosphates are one of the common poisonings in tropical countries such as India, causing both central and peripheral nervous system manifestations. We describe a middle-aged male farmer with unexplained altered consciousness and respiratory depression. After 2 days, he developed opsoclonus-myoclonus, and then bronchorrhoea and bradycardia, raising suspicion of organophosphate poisoning. After we had identified a very low serum cholinesterase concentration, he disclosed having consumed organophosphates.

[Caregiving in an exceptional environment: the military operating theater nurse in a tropical zone]. / Soignant en milieu d'exception : l'infirmier de bloc opératoire militaire en zone tropicale.

The profession of operating theater nurse in the French Armed Forces Medical Corps is often little-known. Called upon to serve in mainland France, but also deployed on overseas operations, they provide medical and surgical support to the French armed forces. Personal qualities - human, physical and technical - are essential to adapt to the environmental constraints of this isolated post.

Molecular Surveillance for Imported Antimicrobial Resistant Plasmodium falciparum, Ontario, Canada.

Single-nucleotide polymorphisms at several loci have been correlated with Plasmodium falciparum drug resistance. We examined the prevalence of resistance markers in P. falciparum from imported malaria cases in Canada during 3 time periods, 2008-2009, 2013-2014, and 2017-2018. We evaluated single-nucleotide polymorphisms at atpase6 (pfATPase6), pfcrt (chloroquine resistance transporter), cytb (cytochrome b), dhfr (dihydrofolate reductase), dhps (dihydropteroate synthetase), mdr1 (multidrug resistance protein) and mdr1 copy number, and kelch13 (kelch protein gene on chromosome 13). Over time, we observed increasing mutant genotypes for dhfr S108N and dhps A613T and decreasing mutant genotypes for mdr1 N86Y, D1246Y, pfcrt K76T, and pfcrt 74-75; we identified no kelch13 mutations. We observed fewer mutations indicative of chloroquine resistance over time, which may reflect reduced chloroquine pressure in specimens from travelers to Africa. Mutations conferring proguanil resistance increased over time. Minor genotypes confirm the heterogeneous nature of infection and may affect treatment success.

Barriers to seeking health care among returning travellers with malaria: A systematic review.

OBJECTIVE: To identify barriers to seeking health care among returning travellers with malaria with the aim of developing targeted interventions that improve early health care-seeking behaviour, diagnosis and treatment. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review of published medical literature, selecting studies that investigated and reported barriers to seeking health care among returning travellers and migrants with malaria. In total, 633 articles were screened, of which four studies met the inclusion criteria after a full-text review. RESULTS: The four studies reported barriers to seeking healthcare among returning travellers in China, the United States, Thailand and the Dominican Republic. Three studies had an observational design. The identified barriers were summarised based on the appraisal delay, illness delay and utilisation delay stages. During appraisal delays, low awareness of malaria was the most significant factor. Once the patient assessed that he or she was ill, belonging to a specific minority ethnicity, being infected with P. vivax and receiving a low level of social support were predictors of delayed health care-seeking. Finally, the most significant factor associated with utilisation delays was the monetary cost. CONCLUSION: The health care-seeking behaviour of returning travellers with malaria should be further investigated and improved. Addressing the identified barriers and gaps in health care-seeking behaviour among returning travellers with malaria, particularly among groups at high risk of travel-associated infections, is important to prevent severe disease and deaths as well as secondary transmission and epidemics.

Challenges in diagnosing fever in traveler returning from tropical ares - is it dengue or chikungunya? Case report.

Arthropod-borne viral infections caused by dengue virus (DENV) and chikungunya virus (CHIKV) are prevalent in the same regions and are spread by the same mosquito type (Aedes) and have similar clinical manifestations. This study emphasized the challenges of diagnosing fever in a patient returning from a tropical area. We report a case of a 52-year-old patient who presented with fever, myalgia, and headache after travelling to Laos and Thailand. After ten days of the disease, the diagnosis of chikungunya was made. Recent travel history should be a standard part of assessment when consulting febrile patients and is essential for further diagnosis. Malaria should permanently be excluded from travellers returning from tropical regions with fever. In the differential diagnosis, dengue, chikungunya, and other mosquito-borne infections should be considered. Patients wishing to travel to such areas need to be educated beforehand on the necessary preventative measures.

Increased Incidence of Melioidosis in Far North Queensland, Queensland, Australia, 1998-2019.

During January 1998-December 2019, the annual incidence of melioidosis in Far North Queensland, Queensland, Australia, more than doubled. Because climate and prevalence of predisposing medical conditions remained stable during that time, we hypothesize that the increased incidence was caused by urban expansion and increased construction, resulting in greater exposure to Burkholderia pseudomallei.

Spatial analysis of tuberculosis cure in primary care in Rio de Janeiro, Brazil.

BACKGROUND: Tuberculosis (TB) presents a high burden of disease and is considered a global emergency by the World Health Organization (WHO), as the leading cause of death from infectious disease in adults. TB incidence is related directly to access to health services and socioeconomic determinants and inequality. Providing primary care settings can lead to improved access, shorter waiting times for patients, and enhanced TB case detection. The article aims to identify the spatial and temporal risk areas for TB and the relationship between TB cure and primary healthcare coverage from 2012 to 2014 in Rio de Janeiro, Brazil. METHODS: A cross-sectional study was conducted in Rio de Janeiro, Brazil. All cases of TB reported to the Information System on Diseases of Notification (SINAN) from 2012 to 2014 were included. Socioeconomic variables from the 2010 Brazilian national census were also added. Socioeconomic variables were selected from multivariate analysis using principal factors analysis. Spatial association was verified with generalized additive model (GAM). It was possible to identify areas at higher risk of failure to cure TB. RESULTS: TB rates showed strong positive spatial autocorrelation. TB cure rate varied according to schooling (individuals with complete secondary schooling had higher cure rates than illiterate individuals; OR 1.72, 95% CI 1.30-2.29), alcohol consumption (OR 0.47, 95% CI 0.35-0.64), contact investigation (OR 2.00, 95% CI 1.56-2.57), positive HIV serology (OR 0.31, 95% CI 0.23-0.42), and census tracts with higher elderly rates (OR 9.39, 95% CI 1.03-85.26). Individuals who had been covered by primary healthcare (PHC) for 35 to 41 months had 1.64 higher odds of cure, compared to those with no PHC coverage (95% CI 1.07-2.51). CONCLUSION: A comprehensive risk map was developed, allowing public health interventions. Spatial analysis allowed identifying areas with lower odds of TB cure in the city of Rio de Janeiro. TB cure was associated statistically with time of coverage by primary healthcare. TB cure rate also varied according to sociodemographic factors like schooling, alcohol abuse, and population density. This methodology can be generalized to other areas and/or other public health problems. HIGHLIGHTS: We studied standardized municipal TB cure rates in an area of social inequality in Brazil. TB rates showed strong positive spatial autocorrelation. Higher rates were associated with population density and socioeconomic conditions. Illiterate individuals were less likely to achieve TB cure. TB cure was less likely in individuals with HIV and alcohol abuse. TB cure was greater in areas with high primary healthcare coverage.

Review on therapeutic targets for COVID-19: insights from cytokine storm.

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been caused the greatest pandemic of our century. Many of the deaths related to it are due to a systemic inflammatory response, which has been called 'cytokine storm'. OBJECTIVES: We developed a comprehensive review of the pathophysiology mechanisms of COVID-19 and of the rationale for drugs and therapeutics that have been tested in clinical trials. METHODS: A narrative review of the literature was conducted using PubMed, SciELO, Bireme, Google Scholar and ClinicalTrials. RESULTS: SARS-CoV-2 has evolutive mechanisms that made it spread all around the globe, as a higher latency period and a lesser lethality than other coronaviruses. SARS-CoV-2 causes a delay in the innate immune response and it disarranges the immune system leading to an overwhelming inflammatory reaction (the 'cytokine storm'). In this scenario, high levels of interleukins (IL), notably IL-6 and IL-1, create a positive feedback of chemokines and immune responses, and powers pulmonary and systemic tissue damage, leading to capillary leakage and SARS, the main cause of death in patients with COVID-19. On 17 July 2020, there were 1450 entries on ClinicalTrials.gov of ongoing studies on COVID-19. The mechanisms of the main therapeutic approaches were comprehensively reviewed throughout the text. Therapies focus on blocking viral entry (remdesivir, umifenovir, among others) and blocking of immune system for cytokine storm control (IL-1 and IL-6 inhibitors, glucocorticoids, convalescent plasma, among others). CONCLUSIONS: Understanding of action mechanisms of SARS-CoV-2 enables us to direct efforts on effective therapeutic targets. This comprehensive review helps to interpret the clinical results of the several trials ongoing.

Critical care medicine in the French Territories in the Americas: Current situation and prospects.

Hospitals in the French Territories in the Americas (FTA) work according to international and French standards. This paper aims to describe different aspects of critical care in the FTA. For this, we reviewed official information about population size and intensive care unit (ICU) bed capacity in the FTA and literature on FTA ICU specificities. Persons living in or visiting the FTA are exposed to specific risks, mainly severe road traffic injuries, envenoming, stab or ballistic wounds, and emergent tropical infectious diseases. These diseases may require specific knowledge and critical care management. However, there are not enough ICU beds in the FTA. Indeed, there are 7.2 ICU beds/100 000 population in Guadeloupe, 7.2 in Martinique, and 4.5 in French Guiana. In addition, seriously ill patients in remote areas regularly have to be transferred, most often by helicopter, resulting in a delay in admission to intensive care. The COVID-19 crisis has shown that the health care system in the FTA is unready to face such an epidemic and that intensive care bed capacity must be increased. In conclusion, the critical care sector in the FTA requires upgrading of infrastructure, human resources, and equipment as well as enhancement of multidisciplinary care. Also needed are promotion of training, research, and regional and international medical and scientific cooperation.

Los hospitales en los territorios franceses de la Región de las Américas funcionan según las normas francesas e internacionales. El objetivo de este artículo es describir distintos aspectos de los cuidados intensivos en los territorios franceses. Para ello, hemos revisado los datos oficiales sobre el tamaño de la población y el número de camas de las unidades de cuidados intensivos (UCI), así como la bibliografía sobre algunos aspectos específicos de las UCI, en los territorios franceses. Las personas que viven en los territorios franceses, o que están de visita en ellos, están expuestas a riesgos específicos: principalmente traumatismos graves causados por el tránsito, envenenamiento por mordeduras, heridas de bala o por apuñalamiento, y enfermedades infecciosas tropicales emergentes. La atención de estos traumatismos y enfermedades puede requerir conocimientos específicos y cuidados intensivos. Sin embargo, no hay suficientes camas de UCI en los territorios franceses. De hecho, hay 7,2 camas de UCI por 100 000 habitantes en Guadalupe, 7,2 en Martinica y 4,5 en Guayana Francesa. Además, los pacientes gravemente enfermos que viven en zonas remotas a menudo tienen que ser trasladados, normalmente por helicóptero, lo que retrasa su ingreso en la unidad de cuidados intensivos. La crisis de la COVID-19 ha puesto de manifiesto que el sistema de atención de salud en los territorios franceses no está preparado para enfrentarse a una epidemia de estas dimensiones y que debe aumentarse la capacidad hospitalaria de las unidades de cuidados intensivos. En conclusión, el sector de los cuidados intensivos en los territorios franceses tiene que mejorar su infraestructura, recursos humanos y equipamiento, así como perfeccionar la atención multidisciplinaria. También es necesario promover la capacitación, la investigación y la cooperación médica y científica, tanto regional como internacional.

Os hospitais nos territórios ultramarinos franceses nas Américas funcionam segundo os padrões franceses e internacionais. O objetivo deste artigo é descrever os diversos aspectos da atenção intensiva nesta região. Analisamos os dados oficiais relativos ao tamanho da população e ao número de leitos de unidade de terapia intensiva (UTI) nestes territórios junto com uma revisão da literatura científica sobre as características particulares destes centros de terapia intensiva. Os residentes locais ou visitantes dos territórios ultramarinos franceses nas Américas são expostos a riscos específicos, sobretudo acidentes de trânsito graves, envenenamentos por animais peçonhentos, ferimentos por armas brancas ou armas de fogo e doenças infecciosas tropicais emergentes que requerem conhecimento especializado e atenção intensiva. Porém, não há leitos suficientes de UTI nos territórios ultramarinos franceses nas Américas: são 7,2 leitos de UTI por 100.000 habitantes em Guadalupe, 7,2 na Martinica e 4,5 na Guiana Francesa. Ademais, em áreas remotas, os pacientes em estado crítico frequentemente precisam ser transferidos por helicóptero, o que causa demora na internação em UTI. A crise da COVID-19 demonstra o despreparo do sistema de saúde para enfrentar a pandemia e a necessidade de aumentar o número de leitos de UTI nestes territórios. Em conclusão, é imprescindível modernizar a infraestrutura e os equipamentos, capacitar melhor os recursos humanos e melhorar a atenção multidisciplinar. Incentivar a formação profissional, pesquisa e cooperação médico-científica regional e mundial é também fundamental.

Traumatic Neck Injury: An Accidental Impalement by a Needlefish.

Encounters between marine animals and humans can result in critical injury and fatal complications. We highlight a 20-y-old male who sustained a penetrating injury to the neck as a result of impalement by needlefish (Tylosurus sp) while snorkeling. He sustained a penetrating injury in the posterior triangle of the neck. On presentation, he was stabilized and received empirical antibiotics, analgesia, and antitetanus toxoid injection before being transferred to a tertiary center. On presentation to the tertiary hospital, the patient was hemodynamically stable with no clinical evidence of injury to surrounding neck structures, and this was confirmed using computed tomography. The patient underwent local wound exploration and retrieval of the needlefish beak under general anesthesia. The wound was left open to heal by secondary intention. The patient was discharged with oral antibiotics and went on to make a complete recovery.
