Background In October 2010, Haiti was struck by a large-scale cholera epidemic. The Haitian government, UNICEF and other international partners launched an unprecedented nationwide alert-response strategy in July 2013. Coordinated NGOs recruited local rapid response mobile teams to conduct case-area targeted interventions (CATIs), including education sessions, household decontamination by chlorine spraying, and distribution of chlorine tablets. An innovative red - orange - green alert system was also established to monitor the epidemic at the communal scale on a weekly basis. Our study aimed to describe and evaluate the exhaustiveness, intensity and quality of the CATIs in response to cholera alerts in Haiti between July 2013 and June 2017. Methodology/principal findings We analyzed the response to 7,856 weekly cholera alerts using routine surveillance data and severity criteria, which was based on the details of 31,306 notified CATIs. The odds of CATI response during the same week (exhaustiveness) and the number of complete CATIs in responded alerts (intensity and quality) were estimated using multivariate generalized linear mixed models and several covariates. CATIs were carried out significantly more often in response to red alerts (adjusted odds ratio (aOR) [95%-confidence interval, 95%-CI], 2.52 [2.22–2.87]) compared with orange alerts. Significantly more complete CATIs were carried out in response to red alerts compared with orange alerts (adjusted incidence ratio (aIR), 1.85 [1.73–1.99]). Over the course of the eight-semester study, we observed a significant improvement in the exhaustiveness (aOR, 1.43 [1.38–1.48] per semester) as well as the intensity and quality (aIR, 1.23 [1.2–1.25] per semester) of CATI responses, independently of funds available for the strategy. The odds of launching a CATI response significantly decreased with increased rainfall (aOR, 0.99 [0.97–1] per each accumulated cm). Response interventions were significantly heterogeneous between NGOs, communes and departments. Conclusions/significance The implementation of a nationwide case-area targeted rapid response strategy to control cholera in Haiti was feasible albeit with certain obstacles. Such feedback from the field and ongoing impact studies will be very informative for actors and international donors involved in cholera control and elimination in Haiti and in other affected countries.
Pseudohypoparathyroidism (PHP) is a group of disorders characterized by end-organ resistance to the parathyroid hormone (PTH). PHP type 1A includes multihormone resistance syndrome, Albright's hereditary osteodystrophy, and obesity and is caused by mutations in GNAS exon 1 through 13. PHP type 1B (PHP1B), caused by epigenetic changes in the GNAS locus, was initially described as an isolated resistance to PTH. Epigenetic changes in GNAS have also been reported in patients who display mild Albright's hereditary osteodystrophy or mild thyroid-stimulating hormone (TSH) resistance without mutation of GNAS. Here we report a case of PHP caused by epigenetic changes in GNAS in a patient with congenital hypothyroidism. The patient was referred for a positive newborn screening for hypothyroidism (TSH 50 mIU/L). She exhibited severe clinical features of congenital hypothyroidism. The thyroid was in place, and etiologic explorations were negative. TSH was normalized under L-thyroxin, and the symptoms disappeared, except for a macroglossia. In childhood, PHP was suspected in addition to elevated PTH, obesity, brachydactyly, and a rounded face. Sequencing, methylation analysis, and large deletion research were performed in GNAS. No genetic mutations were found. Methylation analysis revealed a broad epigenetic defect without deletion in GNAS consistent with sporadic PHP1B. The multilocus methylation analysis were negative. This finding expands the known onsets of PHP1B and emphasizes the need for a new PHP classification system. This case report has important consequences for the etiologic diagnosis of congenital hypothyroidism because it adds a new cause of the disease.
A ≥ 80% compliance with pre-travel counseling in children traveling overseas was achieved only for drinking bottled water, using repellents, a routine vaccine update, and yellow fever immunization.
We report the case of a 10-year-old boy with acute-onset diplopia and ptosis in the right eye. CR was positive for SARS-CoV-2. The patient was managed successfully with corticosteroids. We highlight the need for heightened suspicion of occult COVID-19 infection among children presenting with unusual III nerve palsy.
The epidemiology of paediatric bone and joint infections from South America is poorly known. We herein report a retrospective study conducted in whole French Guiana from January 2010 to December 2015. Medical charts of 55 previously healthy children were analysed, identifying 27 with osteomyelitis, 22 with septic arthritis and 6 with multifocal infections and/or osteoarthritis. The male:female ratio was 2.2:1, and the mean age was 7.5 years. Eighty percent children were ≥36 months old who had predominantly osteomyelitis related to methicillin-susceptible Staphylococcus aureus (p < 0.05) in the course of neglected skin infections. Five children presented with multi-systemic infections resulting in one fatality, mainly caused by S. aureus producing Panton-Valentine leucocidin (p < 0.01). In contrast, children aged 6-36 months had more likely culture-negative infections (p < 0.05), septic arthritis and mild clinical and biological features. Further prospective studies are required to better guide rational diagnostic and therapeutic strategies.
Objectives The aim of this study was to evaluate the differences in surgical capacity for head and neck cancer in the UK between the first wave (March‐June 2020) and the current wave (Jan‐Feb 2021) of the COVID‐19 pandemic. Design REDcap online‐based survey of hospital capacity. Setting UK secondary and tertiary hospitals providing head and neck cancer surgery. Participants One representative per hospital was asked to report the capacity for head and neck cancer surgery in that institution. Main outcome measures The principal measures of interests were new patient referrals, capacity in outpatients, theatres and critical care; therapeutic compromises constituting delay to surgery, de‐escalated surgery and therapeutic migration to non‐surgical primary modality. Results Data were returned from approximately 95% of UK hospitals with a head and neck cancer surgery specialist service. 50% of UK head and neck cancer patients requiring surgery have significantly compromised treatments during the second wave: 28% delayed, 10% have received radiotherapy‐based treatment instead of surgery, and 12% have received de‐escalated surgery. Surgical capacity has been more severely constrained in the second wave (58% of pre‐pandemic level) compared with the first wave (62%) despite the time to prepare. Conclusions Some hospitals are overwhelmed by COVID‐19 and unable to offer essential cancer surgery, but all have neighbouring hospitals in their region retaining good (or even normal) capacity. It is noteworthy that very few patients have been appropriately redirected away from the hospitals most constrained by their burden of COVID‐19. The paucity of an effective central or regional strategic response to this evident mismatch between demand and surgical capacity is to the detriment of our head and neck cancer patients.
Objectives: High-resolution manometry (HRM) is the gold standard for diagnosis of esophageal motility disorders. However, clinical signs associated with these disorders are nonspecific, and it is difficult to correlate clinical signs with HRM data. The main objective of our study was to assess the positive predictive value (PPV) and negative predictive value (NPV) of each clinical sign, as well as their sensitivity and specificity in the diagnosis of esophageal motility disorders. Methods: This is a bicentric retrospective cohort study based on HRM data collected between May 2012 and May 2016. The studied symptoms were weight loss, feeding difficulties, swallowing disorders, dysphagia, food blockages, vomiting, gastroesophageal reflux disease (GERD), belching, and respiratory symptoms. HRM data were analyzed according to the Chicago Classification (3.0). Results: In total, 271 HRM data were analyzed, of which 90.4% showed abnormal results. HRM was well tolerated in 91% of the cases. The most common esophageal motility disorder was ineffective esophageal motility (38%). Weight loss was significantly associated (P = 0.003) with an abnormal HRM with a 96% PPV. Conclusions: With nonspecific clinical signs suggesting an esophageal motility disorder, weight loss was a predictive sign of abnormal HRM results. HRM was well tolerated in pediatric patients, and ineffective esophageal motility appears to be the most frequent motility disorder in our cohort, as already observed in adult patient studies.
Background -A massive cholera epidemic struck Haiti on October 2010. As part of the national cholera elimination plan, the Haitian government, UNICEF and other international partners launched a nationwide alert-response strategy from July 2013. This strategy established a coordinated methodology to rapidly target cholera-affected communities with WaSH (water sanitation and hygiene) response interventions conducted by field mobile teams. An innovative red-orange-green alert system was established, based on routine surveillance data, to weekly monitor the epidemic. Methodology/Principal findings -We used cholera consolidated surveillance databases, alert records and details of 31,306 response interventions notified by WaSH mobile teams to describe and assess the implementation of this approach between July 2013 and June 2017. Response to red and orange alerts was heterogeneous across the country, but significantly improved throughout the study period so that 75% of red and orange alerts were responded within the same epidemiological week during the 1 st semester of 2017. Numbers of persons educated about cholera, houses decontaminated by chlorine spraying, households which received water chlorination tablets and water sources that were chlorinated during the same week as cholera alerts significantly increased. Alerts appeared to be an interesting and simple indicator to monitor the dynamic of the epidemic and assess the implementation of response activities. Conclusions/Significance -The implementation of a nationwide alert-response strategy against cholera in Haiti was feasible albeit with certain obstacles. Its cost was less than USD 8 million per year. Continuing this strategy seems essential to eventually defeat cholera in Haiti while ambitious long-term water and sanitation projects are conducted in vulnerable areas. It constitutes a core element of the current national plan for cholera elimination of the Haitian Government.
