Multi-organ involvement caused by Scedosporium apiospermum infection after near drowning: a case report and literature review.

BACKGROUND: Scedosporium apiospermum (S. apiospermum) is a rare fungal pathogen that causes disseminated infections. It rarely affects immunocompetent individuals and has a poor prognosis. CASE PRESENTATION: A 37-year-old woman presented with multiple lesions in the lungs, brain, and eyes, shortly after near drowning in a car accident. The primary symptoms were chest tightness, limb weakness, headache, and poor vision in the left eye. S. apiospermum infection was confirmed by metagenomic next-generation sequencing (mNGS) of intracranial abscess drainage fluid, although intracranial metastases were initially considered. After systemic treatment with voriconazole, her symptoms improved significantly; however, she lost vision in her left eye due to delayed diagnosis. CONCLUSION: While S. apiospermum infection is rare, it should be considered even in immunocompetent patients. Prompt diagnosis and treatment are essential. Voriconazole may be an effective treatment option.

A systematic review and disability-adjusted life years of Scedosporium/Lomentospora infection in patients after near-drowning.

Scedosporium/Lomentospora species exist as saprophytic moulds that can potentially lead to serious infections in patients who have experienced near-drowning incidents. Scedosporium species are distributed across different regions of the world while Lomentospora prolificans has quite a restricted geographic distribution. We aimed to systematically review scedosporiosis cases after near-drowning, their clinical manifestations, underlying diseases, treatments, outcomes and its impact through disability-adjusted life years (DALYs). Five available sources were searched from 1 January 2007, to 20 April 2022. Thirty-eight studies, including 41 patients, were evaluated. Mean age was 33.6 ± 18.6 years (range 1-68), and 28 were male (68.3%). Central nervous system (CNS) dissemination predominated (36/41; 87.8%), presenting mainly as multiple brain abscesses (26/41; 63.4%), followed by lung involvement (22/41; 56.4%). Scedosporium apiospermum species complex was the most causative agent (38/41; 92.7%). Overall mortality was 51.2%. Half of the patients (18/37) were cured after receiving proper treatment, and in most cases, voriconazole alone or in combination with surgery or other antifungals caused survival. The mean survival time was 123 ± 27 days. Mean DALYs in 1980-2022 were 46.110 ± 3.318 (39.607-52.612). Time to diagnosis was estimated to be 120 days, and there was no association between time to diagnosis and outcome. Voriconazole is a potentially effective therapy, and combination of surgery and antifungal treatment may lead to more favourable outcome. Advances in early diagnosis and appropriate antifungal therapy may have contributed to reducing its mortality.

Systemic Corticosteroid as an Adjunct for Acute Respiratory Distress Syndrome in Non-Fatal Fresh Water Drowning: An Evidence-based Case Report.

BACKGROUND: Acute lung injury or acute respiratory distress syndrome (ARDS) is one of the most common complications of non-fatal drowning. Although respiratory societies' guidelines endorse the role of systemic corticosteroids in ARDS, the evidence for systemic corticosteroid use in ARDS due to non-fatal drowning is limited. METHODS: A search was conducted on Pubmed, OVID, and EuropePMC, assessing the clinical question using inclusion and exclusion criteria. The selected studies were critically appraised, and the results were summarized. RESULTS: A total of six retrospective studies were selected and assessed, all studies showed poor validity and a high risk of bias. Out of six studies, only four informed us of steroid administration's effect on outcomes. In two studies, mortality associated with corticosteroid administration seemed to be higher. On the contrary, one study found no mortality in the corticosteroid group, but 100% mortality was observed in the control group. In another study, steroid therapy seemed to not affect hospital length of stay or mechanical ventilation rates. CONCLUSION: Corticosteroid administration for non-fatal drowning and its impact on clinical outcomes remains equivocal. Routine administration of corticosteroids is not indicated and should be done on a case-by-case basis.

Predictors for hospital admission of asymptomatic to moderately symptomatic children after drowning.

Drowning is a leading cause of injury-related death worldwide, but there are limited data on the management and disposition of asymptomatic and mildly symptomatic adults and children following a drowning event. Some authors have recommended admission for all drowning victims due to the possibility of respiratory and clinical deterioration in a seemingly well patient. In order to identify predictors for admission and to establish a unified approach for management, we retrospectively collected all children ≤ 16 years old presented following a drowning event to the pediatric ED over a period of 12 years. The children were divided into two groups, those who were discharged home from the ED and those who were admitted. Seventy-one surviving and non-intubated children were asymptomatic to moderately symptomatic, and they comprised the study group. Crepitations on lung auscultation, oxygen desaturation, and respiratory distress were significantly higher in the admitted group (n = 26) compared with the discharged group (n = 45) (P < 0.05). Respiratory distress and lung crepitations were independent predictors for admission. Eventually, 30% of the hospitalized patients required oxygen therapy, but there were no cases that deteriorated and required invasive ventilation. No readmissions occurred in the group of children who were discharged from the ED.Conclusion: Children who after six hours show no respiratory distress and have normal oxygen saturation and normal auscultation can be safely discharged home. Respiratory distress and lung crepitations should both warrant the physician to consider admission of asymptomatic to moderately symptomatic children following a drowning event. An algorithm to assist patient management is proposed. What is Known: •There are few data in the literature regarding the management and disposition of asymptomatic to moderately symptomatic children after drowning. What is New: •We found that respiratory distress and lung crepitations are independent predictors for admission. An algorithm to assist patient management is proposed.

BET 1: cervical spine immobilisation in the management of drowning victims.

A short cut review was carried out to establish whether patients presenting to the emergency department after a near drowning should have cervical spine immobilisation. A search of the literature found only three studies directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that cervical spine injuries are rare in drowning and near drowning unless there is a history of diving or a fall or signs of trauma. Cervical spine immobilisation should be reserved for cases where there is a reasonable suspicion of a spinal injury.

BET 2: CT head in investigation of near drowning.

A short cut review was carried out to establish whether patients presenting to the emergency department after a near drowning should have a CT head scan as part of their initial assessment. A search of the literature found only three studies directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that anyone with GCS≤4 should have a CT head as an abnormal scan at this stage heralds a very poor prognosis.

Can Apparent Diffusion Coefficient Predict the Clinical Outcome in Drowned Children?

INTRODUCTION: Pediatric cerebral hypoxic-ischemic injury frequently results in severe neurological outcome. Imaging with diffusion-weighted magnetic resonance imaging (DWi) demonstrates that the acute cerebral injury and apparent diffusion coefficient (ADC) allow the assessment of the severity of brain damage. The main objective was to examine if spatial distribution of reductions in ADC values is associated with clinical outcome in drowned children. METHODS: This is a retrospective study of 7 children (7 examinations) suffering from a hypoxic-ischemic event who underwent DWi. Seven subjects with normal DWi served as controls. The mean patient age was 4.88 ± 2.93 years and the male-to-female ratio was 5:2. The neurological outcome was divided into 2 categories: 4 children with Apallic syndrome and 3 deaths. We analysed the differences between the drowned children and the control group regarding clinical data, DWi abnormalities, and ADC values. RESULTS: The ADC values in the occipital and parietal grey matter were significantly different between the drowned children (765.14 ± 65.47 vs 920.95 ± 69.62; P = .003) and the control group (670.82 ± 233.99 vs 900.66 ± 92.72; P = .005). The ADC showed low values in the precentral area also (P = .044). CONCLUSION: The ADC reduction may be useful to predict the poor outcome in drowned children and can be a valuable tool for clinical assessment.

Targeted Temperature Management After Pediatric Cardiac Arrest Due To Drowning: Outcomes and Complications.

OBJECTIVE: To describe outcomes and complications in the drowning subgroup from the Therapeutic Hypothermia After Pediatric Cardiac Arrest Out-of-Hospital trial. DESIGN: Exploratory post hoc cohort analysis. SETTING: Twenty-four PICUs. PATIENTS: Pediatric drowning cases. INTERVENTIONS: Therapeutic hypothermia versus therapeutic normothermia. MEASUREMENTS AND MAIN RESULTS: An exploratory study of pediatric drowning from the Therapeutic Hypothermia After Pediatric Cardiac Arrest Out-of-Hospital trial was conducted. Comatose patients aged more than 2 days and less than 18 years were randomized up to 6 hours following return-of-circulation to hypothermia (n = 46) or normothermia (n = 28). Outcomes assessed included 12-month survival with a Vineland Adaptive Behavior Scale score of greater than or equal to 70, 1-year survival rate, change in Vineland Adaptive Behavior Scale-II score from prearrest to 12 months, and select safety measures. Seventy-four drowning cases were randomized. In patients with prearrest Vineland Adaptive Behavior Scale-II greater than or equal to 70 (n = 65), there was no difference in 12-month survival with Vineland Adaptive Behavior Scale-II score of greater than or equal to 70 between hypothermia and normothermia groups (29% vs 17%; relative risk, 1.74; 95% CI, 0.61-4.95; p = 0.27). Among all evaluable patients (n = 68), the Vineland Adaptive Behavior Scale-II score change from baseline to 12 months did not differ (p = 0.46), and 1-year survival was similar (49% hypothermia vs 42%, normothermia; relative risk, 1.16; 95% CI, 0.68-1.99; p = 0.58). Hypothermia was associated with a higher prevalence of positive bacterial culture (any blood, urine, or respiratory sample; 67% vs 43%; p = 0.04); however, the rate per 100 days at risk did not differ (11.1 vs 8.4; p = 0.46). Cumulative incidence of blood product use, serious arrhythmias, and 28-day mortality were not different. Among patients with cardiopulmonary resuscitation durations more than 30 minutes or epinephrine doses greater than 4, none had favorable Pediatric Cerebral Performance Category outcomes (≤ 3). CONCLUSIONS: In comatose survivors of out-of-hospital pediatric cardiac arrest due to drowning, hypothermia did not result in a statistically significant benefit in survival with good functional outcome or mortality at 1 year, as compared with normothermia. High risk of culture-proven bacterial infection was observed in both groups.

Intrathecal baclofen therapy in children with acquired brain injuries after drowning: A case series.

UNLABELLED: Objective: To investigate clinical efficacy as well as the incidence and extent of complications regarding intrathecal baclofen (ITB) therapy in children. METHODS: This is a retrospective medical chart review of three paediatric patients with acquired brain injuries (ABI) resulting from drowning who underwent ITB pump implantation for treatment of severe spasticity. RESULTS: Compared to the pre-operative state, ITB therapy reduced spasticity with a corresponding decrease of modified Ashworth scale in upper (3.2 ± 1.4 to 1.3 ± 0.6) and lower extremities (3.5 ± 0.9 to 2.0 ± 1.0). Overall, six complications, five device-related and one accidental, were found in two out of three patients. CONCLUSION: Intrathecal baclofen is an effective therapy option for paediatric patients with ABI after drowning to significantly reduce spasticity of upper and lower extremities. A word of caution must be addressed to the incidence and extent of complications related to ITB therapy.

Acute respiratory distress syndrome (ARDS) treated successfully by veno-venous extracorporeal membrane oxygenation (ECMO) in a nearly drowned patient.

This report highlights about one acute respiratory distress syndrome (ARDS) case after near-drowning resuscitated using extracorporeal membrane oxygenation (ECMO). Few cases have been reported about ECMO use for near-drowning and in most of these cases, ECMO was initiated within the first week. However, in our report, we would like to emphasize that seemingly irreversible secondary worsening of ARDS after nearly drowned patient was successfully treated by ECMO use more than 1 week after near-drowning followed by discharge without home oxygen therapy, social support, or any complication. This is probably due to sufficient lung rest for ventilator-associated lung injury during ECMO use. Based on our case's clinical course, intensive care unit physicians must consider ECMO even in the late phase of worsened ARDS after near-drowning.

Surfactant for acute respiratory distress syndrome caused by near drowning in a newborn.

BACKGROUND: Near drowning is the term for survival after suffocation caused by submersion in water or another fluid. Pulmonary insufficiency may develop insidiously or suddenly because of near drowning. AIM: We want to present a newborn case of acute respiratory distress syndrome caused by near drowning. CASE: A 26-day-old boy was brought to the emergency department because of severe respiratory distress. Two hours before admission, the baby suddenly slipped out his mother's hands and fell in the bathtub full of water while bathing. After initial resuscitation, he was transferred to the neonatal intensive care unit for mechanical ventilation. PaO2/FIO2 ratio was 97, with SaO2 of 84%. Bilateral heterogeneous densities were seen on his chest x-ray film. The baby was considered to have acute respiratory distress syndrome. Antibiotics were given to prevent infection. Because conventional therapy failed to improve oxygenation, a single dose of surfactant was tested via an intubation cannula. Four hours later, poractant alfa (Curosurf) administered repeatedly at the same dosage because of hypoxemia (PaO2/FIO2 ratio, 124; SaO2, 88%). Oxygen saturation was increased to more than 90% in 24 hours, which was maintained for 3 days when we were able to wean him from mechanical ventilation. After 7 days, the x-ray film showed considerable clearing of shadows. He was discharged home on the 15th day after full recovery. CONCLUSIONS: This case report describes a rapid and persistent improvement after 2 doses of surfactant in acute respiratory distress syndrome with severe oxygenation failure caused by near drowning in a newborn.

[From fishing trip to the critical care unit : Successful resuscitation after a near drowning accident]. / Vom Angelausflug auf die Intensivstation : Erfolgreiche Reanimation nach einem Ertrinkungsunfall.

BACKGROUND: In the context of the European Resuscitation Council (ERC) guidelines, modifications of the proposed treatment algorithm need to be performed in order to respond to different parameters. In this respect several factors interacting with cardiac arrest are essential and need to be included in the therapy. This case report demonstrates an example of resuscitation in the situation of hypothermia. CASE REPORT: After a near drowning accident and approximately 30 min underwater, a patient suffering from severe hypothermia initially required resuscitation after the rescue. A return of spontaneous circulation (ROSC) was successfully achieved within a short length of time and after 15 days on the intensive care unit the patient was discharged to a rehabilitation facility without any signs of focal neurological deficits. DISCUSSION: Section 8 of the ERC guidelines provides additional information for resuscitation under specific conditions. In this case report, hypothermia was one of the main criteria leading to an adjusted pharmacological therapy. Furthermore, selection of the appropriate hospital for an optimal advanced treatment including controlled warming of the patient and management of hypothermia-induced complications had to be evaluated.

[Anchor Fast endotracheal tube securing device for a pediatric patient during therapeutic hypothermia].

A 5-year-old girl was admitted to our hospital after resuscitation from cardiac arrest due to near-drowning accident in a river. On admission, Glasgow Coma Scale score was 7; arterial blood pressure was 113/73 mm Hg; heart rate was 157 beats x min(-1), and percutaneous oxygen saturation was 99% on 10 l x min(-1) of oxygen. The patient was intubated with a 5.0 mm internal diameter endotracheal tube, and therapeutic hypothermia was started for neural protection. Hypothermia in the target temperature of 34 degrees C was maintained for 24 hours using Arctic Sun System. Although the patient had been sedated with fentanyl 0.6-1.2 microg x kg(-1) x hr(-1), midazolam 0.2-0.4 mg x kg(-1) x hr(-1) and dexmedetomidine 0.6-1.0 mirog x kg(-1) x hr(-1), agitation increased during the rewarming period following hypothermia. To avoid accidental extubation, we used Anchor Fast as a device for securing oral endotracheal tube. Anchor Fast kept the tube position properly even though the patient was turned or moved. Seventy-two hours later, she was rewarmed and extubated as scheduled. Ten days after admission, she was discharged without any neurological deficits.

Transient changes in the ST-T waveform mimicking myocardial infarction in a child with near-drowning: a case report.

Drowning is a common cause of childhood morbidity and mortality worldwide. Anoxia, hypothermia, and metabolic acidosis are mainly responsible for this morbidity. Drowning may lead to multiple organ damage, especially cardiac damage, in cases in which severe hypothermia and hypoxemia occur. We report a case of a 4-year-old girl who was admitted to our hospital's Emergency Department because of drowning. She had elevated troponin I concentrations and ST-segment elevation with T wave inversion. However, cardiovascular computed tomography showed no obvious abnormalities in the coronary arteries. We suggest that cardiac damage in this situation is caused by coronary artery spasms. To the best of our knowledge, this is the first case of cardiac damage with electrocardiographic changes after drowning in a preschool child.

Impact of the Tohoku earthquake and tsunami on pneumonia hospitalisations and mortality among adults in northern Miyagi, Japan: a multicentre observational study.

BACKGROUND: On 11 March 2011, the Tohoku earthquake and tsunami struck off the coast of northeastern Japan. Within 3 weeks, an increased number of pneumonia admissions and deaths occurred in local hospitals. METHODS: A multicentre survey was conducted at three hospitals in Kesennuma City (population 74 000), northern Miyagi Prefecture. All adults aged ≥18 years hospitalised between March 2010 and June 2011 with community-acquired pneumonia were identified using hospital databases and medical records. Segmented regression analyses were used to quantify changes in the incidence of pneumonia. RESULTS: A total of 550 pneumonia hospitalisations were identified, including 325 during the pre-disaster period and 225 cases during the post-disaster period. The majority (90%) of the post-disaster pneumonia patients were aged ≥65 years, and only eight cases (3.6%) were associated with near-drowning in the tsunami waters. The clinical pattern and causative pathogens were almost identical among the pre-disaster and post-disaster pneumonia patients. A marked increase in the incidence of pneumonia was observed during the 3-month period following the disaster; the weekly incidence rates of pneumonia hospitalisations and pneumonia-associated deaths increased by 5.7 times (95% CI 3.9 to 8.4) and 8.9 times (95% CI 4.4 to 17.8), respectively. The increases were largest among residents in nursing homes followed by those in evacuation shelters. CONCLUSIONS: A substantial increase in the pneumonia burden was observed among adults after the Tohoku earthquake and tsunami. Although the exact cause remains unresolved, multiple factors including population aging and stressful living conditions likely contributed to this pneumonia outbreak.

Participation of autophagy in acute lung injury induced by seawater.

Seawater drowning can lead to acute lung injury (ALI). However, the molecular and cellular mechanisms underlying this phenomenon remain elusive. The overall aim of this study is to clarify the role of autophagy in seawater-induced ALI, by which we can further understand the molecular mechanism and develop new methods for prevention and treatment of seawater-induced ALI. In this study, electron microscopy, western blot analysis, and RT-PCR were used to detect autophagy in lung tissues. Moreover, arterial blood gas analysis, lung weight coefficient, TNF-α, IL-8 in bronchoalveolar fluid (BALF), histopathology were used to detect the lung injury of seawater exposure. An inhibitor of autophagy (3-Methyladenine, 3-MA) was injected intraperitoneally before seawater exposure to further explore the role of autophagy in ALI. Electron microscopy revealed increasing autophagosomes in alveolar epithelial cell in seawater group compared with the control. The transcription and expression levels (mRNA and protein levels) of the LC3 II significantly increased in lung tissue of seawater group compared with those in control group. Furthermore, the alterations of autophage were basically consistent with the changes in arterial blood gas, lung weight coefficient, TNF-α, IL-8 in BALF and morphologic findings. In addition, inhibition of autophagy by 3-MA partly ameliorated seawater-induced ALI, as indicated by reduced lung weight coefficient and TNF-α in BALF, as well as increased PaO2. In conclusion, seawater aspiration triggered autophagy, and autophagy may be a scathing factor responsible for ALI induced by seawater.

Extracorporeal membrane oxygenation can provide cardiopulmonary support during bronchoscopic clearance of airways after sand aspiration.

BACKGROUND: Sand aspiration occurs in situations of cave-in burial and near-drowning. Sand in the tracheobronchial airways adheres to the mucosa and can cause tracheal and bronchial obstruction, which can be life-threatening even with intensive management. In previous case reports of airway obstruction caused by sand aspiration, fiber optic or rigid bronchoscopy has been effective in removing loose sand, but removal of sand particles lodged in smaller airways has proven challenging and time-consuming. CASE REPORT: In this case report of sand aspiration with acute pulmonary failure, the use of extracorporeal membrane oxygenation for respiratory support allowed more effective removal of sand particles by rigid bronchoscopy and lavage with less patient compromise. CONCLUSION: Our case of sand aspiration is unique in that the patient presents with complex medical problems (mixed respiratory and metabolic acidosis), hypothermia, hypoxemia, and neoplastic conditions. The fact that she survived the sand aspiration and a long inter-hospital transport time (90 min) with inadequate ventilation and oxygenation without apparent ill effects suggests that the measures we took to resuscitate her and extract the sand from her airways were reasonable and appropriate.

Electrolytes imbalance in saltwater near-drowning victims in the Gulf of Thailand.

BACKGROUND: Near-drowning victims in saltwater are expected to have multiple electrolytes imbalance that affected treatment outcome. There are limited data about these parameters in Thailand to guide the treatment plan. OBJECTIVE: To study the characteristic of electrolytes imbalance in saltwater near-drowning victims in the Gulf of Thailand. MATERIAL AND METHOD: Retrospective analytic study of 39 medical records of near-drowning patients admitted to Burapha University Hospital between 2000 and 2010. Characteristics of the patients and serum electrolytes were analyzed by SPSS version 19 for windows. RESULTS: The study included 23 male, 16 female patients. Average age was 14.46 +/- 11.15 years and 19/39 (48.72%) patients were aged 10 or less. The following electrolytes imbalance were identified, hypokalemia 8/39 (20.51%), hypernatremia 12/39 (30.77%), hyperchloremia 15/39 (38.46%), high anion gap 23/39 (58.97%), and hypobicarbonatemia 28/39 (71.79%). Seven out of eight patients in the hypokalemia group were in the high anion gap group. Mean SpO2 in the patients who had high anion gap was significantly lower than those who had normal anion gap (87.06 +/- 17.68% vs. 95.8 +/- 5.94% p = 0.031) without difference in systolic blood pressure (112.59 +/- 14.63 vs. 105.67 +/- 13.98 p = 0.159). Those who were hypotensive significantly had lower bicarbonate (17.00 +/- 3.51 vs. 20.59 +/- 3.81 p = 0.038) and higher anion gap (19.29 +/- 1.799 vs. 16.25 +/- 6.25 p = 0.025) than normotensive patients. CONCLUSION: Hypobicarbonatemia, high anion gap, hypernatremia, and hypokalemia were common in saltwater near-drowning patients in the Gulf of Thailand. The cause of high anion gap was probably due to hypoxia and hypotension.

Perforating Calcinosis Cutis as a Complication of Intraosseous Fluid Infusion in the Setting of a Near-Drowning Event.

Iatrogenic calcinosis cutis represents a subset of calcinosis cutis resulting secondary to treatments or procedures. We present the first report of calcinosis cutis resulting from the intraosseous infusion and one of a few cases with associated transepidermal elimination. A previously healthy 2-year-old female presented with a new-onset unilateral shin rash 1 week following hospitalization for a near-drowning event. A dermatologic exam revealed multiple small, tender, firm, chalky-white papules with surrounding erythema, in addition to two erythematous macules superior and medial to the papular lesions, corresponding to prior intraosseous access sites. The rash persisted despite trials of topical mupirocin and acyclovir cream, prompting a referral to a dermatologist. An excisional biopsy was performed, revealing circumscribed dermal deposits of acellular basophilic material connected to the overlying epidermis through an invaginated keratin plug. A von Kossa silver stain highlighted the deposits, confirming the diagnosis of perforating calcinosis cutis. The lesions did not recur following the excisional biopsy. Iatrogenic calcinosis cutis may be seen as a complication of the infusion of calcium-containing fluids via intraosseous access, in addition to the more commonly observed peripheral intravenous access. Awareness of this disorder is important in order to distinguish it from an infectious mimic and guide the selection of therapy.
