Prevalence of Anxiety and Depression Symptomatology in Adolescents Faced With the Hospitalization of a Loved One in the ICU.

OBJECTIVE: ICU experience is linked to anxiety and depression symptomatology in family members of patients. Minors may be forbidden from visiting. To bring practices in line with evidence, we determined the prevalence of anxiety and depression symptomatology in adolescents visiting a relative in the ICU. DESIGN: One-year prospective observational monocenter study. SETTING: Medical-surgical ICU, University Hospital of Martinique. PATIENTS: Forty-one patients intubated for more than 2 days; 53 adolescents (12-17 yr) first- to third-degree relatives in regular contact (minimum once a month) with patient before hospitalization. INTERVENTIONS: Adolescents with unrestricted ICU access completed a satisfaction survey, anxiety history questionnaire, and psychometric evaluation (Hospital Anxiety and Depression Scale) before the patient's 15th day of hospitalization and extubation. MEASUREMENTS AND MAIN RESULTS: Forty adolescents (75.5%) visited their relative. Possible and probable anxiety and depression symptomatology prevalence was 35.9% and 18.9%, respectively, with no significant difference according to ICU visiting status. Most (80%) reported a lack of information, 40% insufficient consideration, and 27.5% misunderstood the reason for hospitalization. Two (5%) regretted visiting. Probable anxiety and depression symptomatology was associated with first-degree relationship (odds ratio, 9.1 [95% CI, 1.1-78.9]; p = 0.045), past exposure to a traumatic event (odds ratio, 8.7 [1.1-69.0]; p = 0.040) and past sense of threat (odds ratio, 10.4 [1.1-94.5]; p = 0.038). CONCLUSIONS: Anxiety and depression symptomatology is common in adolescent family members of ICU patients. An open visiting policy for adolescents is recommended, with visit planning, information meetings, and individual support from ICU staff.

Guillain-Barré Syndrome Associated With Zika Virus Infection in Martinique in 2016: A Prospective Study.

BACKGROUND: Guillain-Barré syndrome (GBS) has been reported to be associated with Zika virus (ZIKV) infection in case reports and retrospective studies, mostly on the basis of serological tests, with the problematic cross-reacting antibodies of the Flavivirus genus. Some GBS cases do not exhibit a high level of diagnostic certainty. This prospective study aimed to describe the clinical profiles and the frequency of GBS associated with ZIKV during the ZIKV outbreak in Martinique in 2016. METHODS: We recorded prospective data from GBS meeting levels 1 or 2 of diagnostic certainty for the Brighton Collaboration, with proof of recent ZIKV infection and negative screening for etiologies of GBS. RESULTS: Of the sample of 34 patients with suspected GBS during the outbreak, 30 had a proven presence of GBS, and 23 had a recent ZIKV infection. The estimated GBS incidence rate ratio (2016 vs 2006-2015) was 4.52 (95% confidence interval, 2.80-7.64; P = .0001). Recent ZIKV infection was confirmed by urine reverse-transcription polymerase chain reaction (RT-PCR) analysis in 17 cases and by serology in 6 cases. Patients, 65% of whom were male, had a median age of 61 years (interquartile range, 56-71 years) and experienced severe GBS. Electrophysiological tests were consistent with the primary demyelinating form of the disease. CONCLUSIONS: ZIKV infection is usually benign, when symptomatic, but in countries at risk of ZIKV epidemics, adequate intensive care bed capacity is required for management of severe GBS cases. Arbovirus RNA detection by RT-PCR should be part of the management of GBS cases.

Zika virus detection in urine from patients with Guillain-Barré syndrome on Martinique, January 2016.

We report two cases of Guillain-Barré syndrome who had concomitant Zika virus viruria. This viruria persisted for longer than 15 days after symptom onset. The cases occurred on Martinique in January 2016, at the beginning of the Zika virus outbreak. Awareness of this possible neurological complication of ZikV infection is needed.

Factors Associated with Severe Leptospirosis, Martinique, 2010-2013.

To identify factors associated with disease severity, we examined 102 patients with quantitative PCR-confirmed leptospirosis in Martinique during 2010-2013. Associated factors were hypotension, chest auscultation abnormalities, icterus, oligo/anuria, thrombocytopenia, prothrombin time <68%, high levels of leptospiremia, and infection with L. interrogans serovar Icterohaemorrhagiae/Copenhageni.

Candida haemulonii complex, an emerging threat from tropical regions?

BACKGROUND: Candida haemulonii complex-related species are pathogenic yeasts closely related to Candida auris with intrinsic antifungal resistance, but few epidemiological data are available. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed clinical and demographic characteristics of patients with fungemia due to C. haemulonii complex and related species (C. pseudohaemulonii, C. vulturna) reported in France during 2002-2021, and compared them to data of C. parapsilosis fungemia, as they all can be commensal of the skin. We also conducted a study on adult inpatients and outpatients colonized by C. haemulonii complex, managed at the University Hospital of Martinique during 2014-2020. Finally, we performed a literature review of fungemia due to C. haemulonii complex and related species reported in Medline (1962-2022). In total, we identified 28 fungemia due to C. haemulonii complex in France. These episodes were frequently associated with bacterial infection (38%) and high mortality rate (44%), and differed from C. parapsilosis fungemia by their tropical origin, mainly from Caribbean and Latin America. All isolates showed decreased in vitro susceptibility to amphotericin B and fluconazole. In Martinique, we found that skin colonization was frequent in the community population, while colonization was strongly associated with the presence of foreign devices in ICU patients. The literature review identified 274 fungemia episodes, of which 56 were individually described. As in our national series, published cases originated mainly from tropical regions and exhibited high crude mortality. CONCLUSIONS/SIGNIFICANCE: Multidrug-resistant C. haemulonii complex-related species are responsible for fungemia and colonization in community and hospital settings, especially in tropical regions, warranting closer epidemiological surveillance to prevent a potential C. auris-like threat.

Clinical presentation of dengue among patients admitted to the adult emergency department of a tertiary care hospital in Martinique: implications for triage, management, and reporting.

STUDY OBJECTIVE: During dengue epidemics, emergency physicians face large numbers of patients with acute febrile illness. Triage algorithms and appropriate reporting systems are useful to manage patients and prioritize resources. We identify possible adaptations to these systems to improve the management of patients during epidemics. METHODS: In a prospective observational study in the adult emergency department (ED) of a tertiary care hospital, we enrolled all patients with febrile illness and a confirmed diagnosis of dengue (ribonucleic acid identification). We then retrospectively classified cases according to the initial clinical presentation at the ED. RESULTS: We enrolled 715 patients (332 male patients), aged 14 to 91 years (median 35 years). Severe illness was documented in 332 cases (46.4%) and was mostly caused by serotype 2, or a secondary infection of any serotype. Severe forms included dengue hemorrhagic fever or dengue shock syndrome (104/332; 31.3%), severe bleeding (9/332; 2.7%), and acute organ failure (56/332; 16.9%). The other patients with severe illness (171/332; 51.5%) presented with symptoms of presyncope, intense weakness, prolonged gastrointestinal symptoms, and hypotension. This presentation was common during epidemics and appeared to be associated with dehydration and electrolyte loss that improved markedly within 24 hours with saline solution infusion. This group did not have evidence of plasma leakage, although similar features were observed in patients with dengue hemorrhagic fever/dengue shock syndrome. CONCLUSION: Dengue has a wide range of clinical presentations in the ED. Many patients who appear seriously ill on presentation will respond to intravenous fluids.

Mental Health of Adolescent Relatives of Intensive Care Patients: Benefits of an Open Visitation Policy.

BACKGROUND: Symptoms of anxiety and depression are common in adolescents with a loved one in an intensive care unit (ICU) and are known precursors of posttraumatic stress disorder (PTSD). OBJECTIVES: To assess the prevalence of PTSD and associated factors in adolescent (age 12-17 years) relatives of patients in an ICU with an open visitation policy. METHODS: One year after the patient was discharged from the ICU, eligible adolescent relatives completed a satisfaction survey, anxiety history questionnaire, and psychometric evaluations (Hospital Anxiety and Depression Scale and 8-item Children's Revised Impact of Event Scale). RESULTS: Thirty-two patients intubated for >2 days and with a Simplified Acute Physiology Score II >30 were included. Forty-six adolescents with first- to third-degree relationships to the patient, and in regular contact (≥monthly) with the patient before hospitalization, were enrolled. The prevalence of PTSD among the adolescents was 33%. Adolescents who visited the ICU were less likely to report feelings of regret than those who did not visit the ICU (2% vs 9%, P = .01). A past sense of threat (odds ratio [95% CI], 19.4 [1.9-201.2]; P = .01) and anxiety and depression symptoms (odds ratio [95% CI], 9.6 [1.4-63.7]; P = .02) were independent factors associated with probable PTSD. CONCLUSIONS: A cautiously prepared open visiting policy should be maintained for adolescents with a relative in the ICU, because it could prevent feelings of regret and subsequent PTSD. Adolescents with risk factors should be screened and followed up.

Sargassum seaweed health menace in the Caribbean: clinical characteristics of a population exposed to hydrogen sulfide during the 2018 massive stranding.

BACKGROUND: Since 2011, there have been ongoing massive unexplained increases of sargassum seaweed strandings along the coastlines of Caribbean countries. The objective of our study was to describe the clinical characteristics of patients exposed to noxious emissions of decomposing sargassum seaweed. METHODS: This observational study included patients from January 2018 to December 2018 for complaints attributed to decomposing sargassum seaweed. History and geographical characteristics of sargassum seaweed strandings as well as detection of ambient air hydrogen sulfide (H2S) levels were documented during the inclusion period. FINDINGS: A total of 154 patients were included. Mean exposure period was 3 months. Neurological (80%), digestive (77%) and respiratory (69%) disorders were the most frequent reasons for medical visit. Temporal distribution of medical visits was related to history of strandings. Geographical origins of patients were consistent with the most impacted areas of strandings as well as the most elevated ambient air H2S levels. INTERPRETATION: The toxicological syndrome induced by sargassum seaweed exposure is close to the toxidrome associated with acute H2S exposure in the range of 0-10 ppm. Our study suggests that patients living in massive stranding areas may be exposed to H2S > 5 ppm for 50 days per year.

Long-term outcome in neuroZika: When biological diagnosis matters.

OBJECTIVE: To characterize the full spectrum, relative frequency, and prognosis of the neurologic manifestations in Zika virus (ZIKV) postnatal infection. METHODS: We conducted an observational study in consecutive ZIKV-infected patients presenting with neurologic manifestations during the French West Indies 2016 outbreak. RESULTS: Eighty-seven patients, including 6 children, were enrolled. Ninety-five percent of all cases required hospitalization. Guillain-Barré syndrome was the most frequent manifestation (46.0%) followed by encephalitis or encephalomyelitis (20.7%), isolated single or multiple cranial nerve palsies (9.2%), other peripheral manifestations (6.9%), and stroke (1.1%). Fourteen patients (16.1%), including one child, developed a mixed disorder involving both the central and peripheral nervous system. Mechanical ventilation was required in 21 cases, all of whom had ZIKV RNA in at least one biological fluid. Two adult patients died due to neuroZika. Clinical follow-up (median 14 months; interquartile range, 13-17 months) was available for 76 patients. Residual disability (modified Rankin Scale score ≥2) was identified in 19 (25.0%) patients; in 6 cases (7.9%), disability was severe (modified Rankin Scale score ≥4). Among patients with ZIKV RNA detected in one biological fluid, the risk of residual disability or death was higher (odds ratio 9.19; confidence interval 1.12-75.22; p = 0.039). CONCLUSIONS: NeuroZika spectrum represents a heterogeneous group of clinical neurologic manifestations. During an outbreak, clinicians should consider neuroZika in patients presenting with cranial nerve palsies and a mixed neurologic disorder. Long-term sequelae are frequent in NeuroZika. ZIKV reverse-transcription PCR status at admission can inform prognosis and should therefore be taken into consideration in the management of hospitalized patients.

Guillain-Barré Syndrome and Chikungunya: Description of All Cases Diagnosed during the 2014 Outbreak in the French West Indies.

The Guillain-Barré syndrome (GBS) has been reported as a possible complication of acute chikungunya infection. The chikungunya epidemics, which occurred in Martinique and Guadeloupe in 2014, affected 308,000 people in these two islands. GBS occurred during or immediately after acute chikungunya infection in 13 patients (10 men, three women; mean age: 61 years). Median time from acute chikungunya to GBS onset was 9 days. Twelve patients were treated with intravenous polyvalent immunoglobulins, nine of whom improved within 7 days. Five of 13 patients required mechanical ventilation. Two patients with severe GBS died. At 6 months of follow-up, 7/13 achieved a good functional recovery with no or minor residual symptoms. A 2-fold increase in incidence was observed during the year of chikungunya outbreak. This study supports prior reports suggesting that GBS may be a complication of chikungunya.

Envenomation by the invasive Pterois volitans species (lionfish) in the French West Indies--a two-year prospective study in Martinique.

CONTEXT: The invasion of the lionfish (Pterois volitans) in the French West Indies represents one of the most important marine invasions by alien species in history. Since its first recognition in Martinique in February 2011, the lionfish presence has strongly progressed, resulting in increasing envenomation cases. Our objective was to report features of lionfish envenomation and outcome. METHODS: A prospective study conducted at the Martinique University Hospital by the emergency departments, general practitioners, and the pre-hospital emergency ambulance service included all the patients referred from November 2011 to February 2014 for one or several stings by lionfish, as strongly suggested by the fish description and the association with marked local pain and edema. Recommended management included immersion of the affected body part in hot water at 35-40 °C for 60 min, analgesics, tetanus toxoid, and antibiotics. RESULTS: 117 patients [98M/19F; age: 42 ± 14 years [mean ± SD]; with significant past morbidities (16%)] were included. Envenomation resulted in marked pain and local edema (100%), paresthesia (90%), abdominal cramps (62%), extensive edema (53%), tachycardia (34%), skin rash (32%), gastrointestinal disorders (28%), fainting (27%), transient weakness (24%), hypertension (21%), hypotension (18%), hyperthermia (9%), bradycardia (3%), hypophosphatemia (12%), elevated aspartate aminotransferase (AST) (10%), and thrombocytopenia (3%). The sting was complicated by local infection (18%) including skin abscess (5%), cellulitis (3%), skin necrosis (3%), and septic arthritis (2%). 26 patients (22%) were hospitalized requiring surgery (8%). Lionfish stings were single (81%) or multiple (19%). Localization was preferentially at one upper (67%) or lower limb (32%). All patients actually improved. Based on multivariate analyses, pain duration > 24 h was significantly associated with skin eruption (p = 0.001) and muscle cramps (p = 0.0002). Local infectious complications occurred more frequently in patients presenting multiple stings (p = 0.008). Immersion in hot water (44%, performed less than 3 h after the sting in 36% of the cases) significantly reduced pain duration (p = 0.02) and local infection (p = 0.02). CONCLUSION: Lionfish represents a major health threat in Martinique with increasing envenomation and significant morbidities. Outcome is favorable if promptly managed, with possible reduction in pain duration and local infections with the rapid immersion of the stung body part in hot water. Our data encourage the authorities to develop investigations on the exact extent of the lionfish invasion and set up a regional taskforce to inform the ecosystem users and register all lionfish-attributed incidents.

Severe manifestations of chikungunya virus in critically ill patients during the 2013-2014 Caribbean outbreak.

OBJECTIVES: A chikungunya epidemic occurred in 2013-2014 in the Caribbean and Americas. Although the disease is usually benign, some patients required admission to the intensive care unit (ICU). The characteristics and outcomes of patients with chikungunya virus (CHIKV) infection admitted to an ICU during this epidemic are reported. METHODS: An observational study of consecutive patients with confirmed CHIKV infection admitted to ICUs in Martinique and Guadeloupe, French West Indies, between January and November 2014, was performed. In addition, patients with CHIKV-related manifestations were compared with those whose manifestations were not specifically related to CHIKV infection. RESULTS: Sixty-five patients were admitted to the ICU with CHIKV infection. Fifty-four (83%) had a pre-existing underlying disease and 27 (41.5%) were admitted due to exacerbation of a comorbidity. Thirty-seven (57%) patients were mechanically ventilated. ICU and hospital mortality rates were 26% and 27%, respectively. CHIKV-related manifestations were observed in 28 (18%) patients and were mainly encephalitis, Guillain-Barré syndrome, and severe sepsis. These patients less frequently had chronic arterial hypertension and diabetes and more frequently had autoimmune diseases compared with patients without CHIKV-related manifestations. CONCLUSIONS: Most patients admitted to the ICU with CHIKV infection had a pre-existing comorbidity. However, severe manifestations such as Guillain-Barré syndrome, encephalitis, and severe sepsis could be specifically related to CHIKV.

Influence of intra-abdominal pressure on the specificity of pulse pressure variations to predict fluid responsiveness.

BACKGROUND: The positive predictive value of pulse pressure variations (ΔPP) to discriminate patients who should respond to volume expansion (VE) may be altered in mechanically ventilated patients. Our goal was to determine whether intra-abdominal pressure (IAP) measurements could discriminate patients with true-positive ΔPP values versus patients with false-positive ΔPP values. METHODS: We designed a prospective pathophysiologic study in a mixed intensive care unit of a university hospital. Sixteen mechanically ventilated patients with hypotension (SAP, <90 mm Hg) and with ΔPP of 13% or more were included. Cardiac output was assessed using Doppler echocardiography before and after VE; IAP was measured using the bladder pressure method. Patients were classified into two groups according to their response to a standardized VE (500 mL of NaCl 0.9%): responders (≥15% increase in cardiac output) and nonresponders. RESULTS: Nine patients (57%) were responders, and seven patients (43%) were nonresponders. Before VE, IAP was statistically higher in nonresponders (15 [11-22] mm Hg vs. 9 [6.5-11] mm Hg; p = 0.008). The area under the curve of the receiver operating characteristic curve was 0.9 ± 0.08. In patients with ΔPP of 13% or more, an IAP cutoff value of 10.5 mm Hg discriminated between responders and nonresponders with a sensitivity of 100% (59-100%) and a specificity of 78% (40-97%). CONCLUSION: An increase in IAP of more than 10.5 mm Hg can decrease the positive predictive value of ΔPP. Hence, in patients prone to present abnormal IAP values, IAP should be measured before performing VE directed by the ΔPP marker. LEVEL OF EVIDENCE: Diagnostic study, level II.

Transesophageal Pulsed Doppler echocardiography of pulmonary venous flow to assess left ventricular filling pressure in ventilated patients with acute respiratory distress syndrome.

OBJECTIVE: To determine whether the systolic fraction (SF) of the pulmonary venous flow (PVF), measured by transesophageal echocardiography (TEE) could be used to estimate the pulmonary artery occlusion pressure (PAOP). DESIGN: Prospective clinical investigation. PATIENTS: Nineteen intubated patients with ARDS. INTERVENTIONS: Doppler examinations with measurement of the SF of the PVF (ie, the systolic velocity-time integral expressed as a fraction of the sum of systolic and early diastolic velocity-time integrals) were performed simultaneously with measurements of PAOP via a right heart catheter at 0 cmH2O PEEP (ZEEP), at PEEP = 8 cmH20 and at PEEP = 16 cmH2O. MEASUREMENTS AND MAIN RESULTS: At ZEEP, PAOP was inversely correlated with the SF of the PVF (r = -.89). The difference of SF between the group with PAOP <18 mm Hg and the group with PAOP > or = 18 mm Hg was statistically significant (P < .05). A SF > or = 55% predicted a PAOP < 15 mm Hg with a positive predictive value of 100% (95% CI = 63-100%). A SF < or = 40% predicted a PAOP > or =18 mm Hg with a positive predictive value of 100% (95% CI = 52-100%). At PEEP = 8 cm H20 (12 patients studied) and at PEEP = 16 cmH2O (10 patients studied), PAOP was inversely correlated with the SF of the PVF: r = -.84, and r = -.85, respectively. CONCLUSION: The SF of the PVF measured by Pulsed Doppler TEE seems to be a valuable index to estimate the left ventricular filling pressure in mechanically ventilated patients with ARDS.

Clinical presentation of dengue by serotype and year of epidemic in Martinique.

During the last decade Martinique experienced four dengue epidemics, each characterized by the predominance of 1 or 2 serotypes. In this retrospective database analysis, we investigated the relationship between dengue serotype and disease severity. Data on dengue were collected from 715 patients (male/female ratio 0.87), 14 to 91 years of age (median 35 years) examined in the adult emergency department between 2005 and 2010. In this series, DENV-4 infections more frequently had a milder clinical presentation. The DENV-2 infections were most often secondary infections admitted at the critical phase of dengue illness with signs of plasma leakage. The DENV-1 infections were disabling, particularly in females, and most often led to disease of intermediate severity, without overt plasma leakage. These data were consistent with there being differences in virulence between serotypes, regardless of the host's immune status. However, secondary DENV-2 infections showed an increased risk of plasma leakage.

Treatment of optic neuritis by plasma exchange (add-on) in neuromyelitis optica.

OBJECTIVE: To assess the contribution of plasma exchange (PE) in association (add-on) with pulsed intravenous corticosteroids in acute optic neuritis of neuromyelitis optica (NMO) and limited forms of NMO. METHODS: Thirty-six patients with optic neuritis were treated from January 1, 1995, through December 31, 2010, with pulsed intravenous corticosteroids and 16 with pulsed intravenous corticosteroids plus PE. The ophthalmologic examination was performed at least 6 months after optic neuritis treatment. Visual acuity and visual field assessed with the Snellen scale and the logarithmic scale of the Early Treatment Diabetic Retinopathy Study were measured using standard automated perimetry and frequency doubling technology perimetry. Retinal peripapillary fiber thickness was measured using optical coherence tomography. RESULTS: Final visual acuity was 20/400 in the corticosteroid group and 20/50 in the PE group (P=.04). The gain in visual acuity was 20/200 in the corticosteroid group and 20/30 in the PE group (P=.01). A poor final visual acuity outcome (≤20/200) was found in 19 of 36 patients (53%) in the corticosteroid group and 2 of 16 patients (13%) in the PE group (P=.008). Mean (SD) thickness of peripapillary retinal nervous fibers was 63.1 (20.4) µm in the corticosteroid group and 70.3 (20.3) µm in the PE group (P=.16). The mean (SD) thickness in the temporal quadrant was 38.5 (14.1) µm in the corticosteroid group and 44.5 (12.7) µm in the PE group (P=.02). In multivariate analysis, PE treatment was the only independent factor associated with a visual acuity greater than 20/200. CONCLUSION: In optic neuritis associated with NMO, sequential treatment with pulsed intravenous corticosteroids and PE is more effective than standard monotherapy with corticosteroids on visual acuity outcome.
