Wind tunnel experiments were performed to investigate turbulent flow over an array of heterogeneous roughness elements using stereoscopic particle image velocimetry. Nine streamwise planes, covering one periodic cell of a multi-scale roughness element that is arranged in a staggered pattern, are combined to quantify mean flow features and Reynolds stresses. Dispersive stresses, arising from spatial variations in the temporally averaged mean velocity, are also presented. The results highlight that the roughness elements create a large deficit pathway along the surfaces. Outer scaling of the time-averaged streamwise velocity presents features which are nearly independent of the roughness element type, with parameters of the flow revealing values near those observed in smooth wall boundary layers, such as the wake strength parameter, opposing the earlier work containing aligned patterns. The strength of the secondary motion is most accentuated at the ridges of the roughness, showing that the formation of structures is sensitive to the location investigated in the spanwise direction.

Introduction
Wernicke’s encephalopathy is a potentially fatal neurological emergency caused by thiamine deficiency. Although it is often associated with chronic alcoholism, it can also occur in all situations that lead to a thiamine deficiency such as undernutrition and exclusive artificial feeding.
ObjectivesIn this work, we propose to study the clinical and treatment concerns of Wernicke’s encephalopathy complicating catatonic schizophrenia.
MethodsWe retrospectively report the case of a patient who developed a Wernicke’s encephalopathy in the aftermath of catatonic schizophrenia.
ResultsMr H.L, a 47-year-old-male has been followed in psychiatric hospital since the age of 27 for catatonic schizophrenia. He has been hospitalized in July 2020 because of oral intake refusal, social isolation and lack of self-care with a poor compliance to treatment. Examination of the patient revealed catalepsy, mutism and negativism. He was treated with antipsychotics drugs, benzodiazepines and parenteral nutrition. About six weeks after his hospitalization, the patient developed horizontal nystagmus and ataxic gait. Magnetic resonance imaging was consistent with Wernicke encephalopathy. Vitamin B1 dosage was 32nmol/l. Parenteral thiamine replacement therapy was initiated with clinical improvement
ConclusionsCatatonic schizophrenia can be associated with severe malnutrition and thus with thiamine deficiency and Wernicke’s encephalopathy. An early intervention by supplying prophylactic thiamine given parenterally in high-risk patients is crucial to avoid Korsakoff syndrome, as well as cardiovascular and neuropsychiatric complications associated with thiamine deficiency.

Introduction: Digital distraction is being integrated into pediatric pain care, but its efficacy is currently unknown. We conducted a systematic review to determine the effect of digital technology distraction on pain and distress for children experiencing acutely painful conditions or medical procedures. Methods: We searched eight online databases (MEDLINE, Embase, Cochrane Library, CINAHL, PsycINFO, IEEE Xplore, Ei Compendex, Web of Science), grey literature sources, scanned reference lists, and contacted experts for quantitative studies where digital technologies were used as distraction for acutely painful conditions or procedures in children. Study selection was performed by two independent reviewers with consensus. One reviewer extracted relevant study data and another verified it for accuracy. Appraisal of risk of bias within studies and the certainty of the body of evidence were performed independently in duplicate, with the final appraisal determined by consensus. The primary outcomes of interest were child pain and distress. Results: Of 3247 unique records identified by the search, we included 106 studies (n = 7820) that reported on digital technology distractors (e.g., virtual reality; videogames) used during common procedures (e.g., venipuncture, minor dental procedures, burn treatments). We located no studies reporting on painful conditions. For painful procedures, digital distraction resulted in a modest but clinically important reduction in self-reported pain (SMD -0.48, 95% CI -0.66 to -0.29, 46 RCTs, n = 3200), observer-reported pain (SMD -0.68, 95% CI -0.91 to -0.45, 17 RCTs, n = 1199), behavioural pain (SMD -0.57, 95% CI -0.94 to -0.19, 19 RCTs, n = 1173), self-reported distress (SMD -0.49, 95% CI -0.70 to -0.27, 19 RCTs, n = 1818), observer-reported distress (SMD -0.47, 95% CI -0.77 to -0.17, 10 RCTs, n = 826), and behavioural distress (SMD -0.35, 95% CI -0.59 to -0.12, 17 RCTs, n = 1264) compared to usual care. Few studies directly compared different distractors or provided subgroup data to inform applicability. Conclusion: Digital distraction provides modest pain and distress reduction for children undergoing painful procedures; its superiority over non-digital distractors is not established. Healthcare providers and parents should strongly consider using distractions as a pain-reduction strategy for children and teens during common painful procedures (e.g., needle pokes, dental fillings). Context, child preference, and availability should inform the choice of distractor.

Background
The prevalence of Human Herpesvirus 8 (HHV8) has never been investigated in schizophrenic patients.
ObjectiveThis study aimed to assess the prevalence of HHV8 serum antibodies in schizophrenic patients and in healthy controls.
MethodsDuring a 24 months period, we consecutively enrolled 108 patients meeting DSM-IV criteria of schizophrenia, in psychiatry department of Sousse Farhat Hached hospital (Tunisia). We also enrolled 108 controls among consenting blood donors. They were age and sex matched and free from any psychotic disorder as screened by MINI-Plus.
Psychopathology and severity were measured using PANSS, BPRS, SANS, SAPS and CGI. Sera samples were obtained from patients and controls and then analyzed for the presence of anti-HHV8 antibodies (anti-HHV8) using a sensitive indirect immunofluorescence assay to latent and lytic HHV8 antigens.
ResultsA significantly higher prevalence of anti-HHV8 in schizophrenic patients than in healthy controls was found (28.7% vs. 14.8%, p = 0.01). Marital status, educational level, professional activity, poverty, promiscuity, number of children, sexual behavior or presence of risk factors of blood transmission were not associated with HHV8 prevalence (p > 0.05). However, among schizophrenic patients, HHV8 prevalence was statically associated with positive symptoms (SAPS score) (p = 0.01) and the severity of illness (CGI score) (p = 0.02).
ConclusionTo our knowledge, this would be the first report of high HHV8 prevalence in schizophrenic patients, which support the role of this virus in the pathogenesis of schizophrenia. To go on further with this hypothesis, more investigations of HHV8 in schizophrenia are needed.

Introduction
Dermatitis artefact (DA) is a self-inflicted skin disease. The exploration of family history and life course of patients could help to better understand the pathogenesis of this disorder.
ObjectiveTo compare family history and life course between patients with DA with patients with other chronic skin disease and siblings.
Materials and methodsThirty female patients meeting DSM-IV criteria of DA were recruited in dermatology department of Farhat Hached hospital (Sousse, Tunisia).
Controls consisted of 30 patients with chronic dermatitis, randomly selected and matched for age and disease duration. For each patient, one sister, the closest in age, was recruited to constitute the siblings group.
ResultCompared with controls, DA patients had lower educational level (p < 10-3), less occupational activity (p = 0.002) and were more often single (p < 10-3). They reported more medical care or prolonged hospitalization in childhood (p = 0.013), more psychiatric disorders (p = 0.006) and more suicide attempts (p = 0.001).
Compared with their sisters, patients with DA had fewer professional activity (p < 103), and were more often single (p < 10-3). They also had more medical history or prolonged hospitalizations during childhood (p = 0.006), more psychiatric disorders (p = 0.002) and more suicide attempts (p = 0.001).
ConclusionCompared to their sisters and to patients with other chronic skin disease, DA patients were more often single, less often professionally active and had more medical care during childhood, psychiatric history and suicide attempts.

Introduction
Psychological profile and quality of life of patients suffering from Dermatitis artefact (DA) have never been assessed in a standardized and comparative way.
ObjectiveTo compare anxiety, depression and quality of life in patients with DA and in patients with other chronic skin illness
Material and methodsThirty patients meeting DSM-IV criteria of Dermatitis artefact were recruited in dermatology department of Farhat Hached hospital (Sousse, Tunisia). Control group consisted of 30 patients with other chronic dermatitis, randomly selected and matched for age and disease duration. Anxiety and depression were assed using the Hospital Anxiety and Depression Scale (HAD-S). Quality of life was measured by the MOS 36-Item Short-Form Health Survey (SF-36).
ResultsCompared with controls, patients with DA had an impaired quality of life (p < 10-3). They had lower scores in physical activity (p = 10-3), limitations due to physical condition (p = 0.024), physical pain (p < 10-3), perception of health (p < 10-3). They also had lower scores in vitality (p = 0.005), social dysfunction (p = 0.003), limitations due to mental condition (p < 10-3) and mental health (p < 10-3). Anxiety and depression scores showed no differences between DA patients and controls.
ConclusionCompared to patients with other chronic dermatological conditions, patients suffering from DA had a more impaired quality of life, but they were no more depressed or anxious.

The objective of this study was to determine the frequency of rheumatoid factors (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in patients with schizophrenia in acute phase and in healthy blood donors (HBD).
Materials and methodsOur retrospective study was performed on 80 patients with schizophrenia newly admitted in closed wards of the department of Psychiatry, Farhat Hached Hospital of Sousse, Tunisia during 2010. Eighty HBD with no history of autoimmune or mental diseases served as controls. Search for RF and anti-CCP antibodies were detected by Enzyme-linked immunosorbent assay (ELISA).
ResultsRF were significantly more frequent in schizophrenic patients than in controls (17.5% vs 3.75%, p = 0.01) and RF-IgM isotype was more frequent in schizophrenic patients than in HBD 12.5%. Anti-CCP was detected only in seven patients with schizophrenia with a frequency of 8.75% and in five HBD with a frequency of 6.25%. The frequency of serological markers of RA (FR IgG or IgA or IgM or anti-CCP) was significantly higher in patients than in HBD (23.75% vs 11.25%, p = 0.037).
ConclusionContrary to literature data, our study found a high frequency of RF in the acute phase of schizophrenia and particularly of the IgM isotype. Thus a large population study would be interesting to confirm this association between the RA and schizophrenia.

Background: Endoscopic endonasal trans-sphenoidal surgery (EETS) is a commonly used approach for the surgical treatment of primary pituitary adenomas. The role of this approach in patients with recurrent disease remains unclear. Here we review a high-volume institutional experience with repeat EETS for recurrent pituitary adenomas and compare outcomes against primary surgeries. Methods: A retrospective chart review of patients who underwent EETS at Toronto Western Hospital from 2008-2016 for pituitary adenomas was completed. Baseline patient characteristics and surgical outcomes were recorded for each surgery. Primary and repeat operations were compared for analysis using Fisher’s exact test and t-test where appropriate. Results: 347 primary and 48 repeat surgery patients were identified. The median follow-up was 3.6 years (range 0-10.6 years). Rates of GTR, optic decompression, endocrinopathy cure, and visual improvement in repeat EETS were 44%, 21%, 22%, and 21%, respectively. While these rates are lower when compared to primary surgeries (75% p<0.001, 58% p<0.001, 75% p=0.01, 37% and p=0.04), they demonstrate that desirable outcomes are still achievable after EETS for recurrent disease. Conclusions: These results from a quaternary-care centre suggest that repeat EETS is a viable option that is safe and effective at improving the visual and endocrine status in select patients with recurrent pituitary disease.

Introduction: Although acute gastroenteritis is an extremely common childhood illness, there is a paucity of literature characterizing the associated pain and its management. Our primary objective was to quantify the pain experienced by children with acute gastroenteritis in the 24-hours prior to emergency department (ED) presentation. Secondary objectives included describing maximum pain, analgesic use, discharge recommendations, and factors that influenced analgesic use in the ED. Methods: Study participants were recruited into this prospective cohort study by the Alberta Provincial Pediatric EnTeric Infection TEam between January 2014 and September 2017. This study was conducted at two Canadian pediatric EDs; the Alberta Children's Hospital (Calgary) and the Stollery Children's Hospital (Edmonton). Eligibility criteria included < 18 years of age, acute gastroenteritis (□ 3 episodes of diarrhea or vomiting in the previous 24 hours), and symptom duration □ 7 days. The primary study outcome, caregiver-reported maximum pain in the 24-hours prior to presentation, was assessed using the 11-point Verbal Numerical Rating Scale. Results: We recruited 2136 patients, median age 20.8 months (IQR 10.4, 47.4); 45.8% (979/2136) female. In the 24-hours prior to enrolment, 28.6% (610/2136) of caregivers reported that their child experienced moderate (4-6) and 46.2% (986/2136) severe (7-10) pain in the preceding 24-hours. During the emergency visit, 31.1% (664/2136) described pain as moderate and 26.7% (571/2136) as severe. In the ED, analgesia was provided to 21.2% (452/2131) of children. The most commonly administered analgesics in the ED were ibuprofen (68.1%, 308/452) and acetaminophen (43.4%, 196/452); at home, acetaminophen was most commonly administered (77.7%, 700/901), followed by ibuprofen (37.5%, 338/901). Factors associated with analgesia use in the ED were greater pain scores during the visit, having a primary-care physician, shorter illness duration, fewer diarrheal episodes, presence of fever and hospitalization. Conclusion: Although children presenting to the ED with acute gastroenteritis experience moderate to severe pain, both prior to and during their emergency visit, analgesic use is limited. Future research should focus on appropriate pain management through the development of effective and safe pain treatment plans.

Introduction: Intranasal dexmedetomidine (IND) is an emerging agent for procedural distress in children. However, studies to date have been limited by small samples and imprecise estimates of effect size. We sought to summarize the evidence on the effectiveness of IND for procedures associated with distress in children. Methods: We performed electronic searches of MEDLINE (1946-2018), EMBASE (1980-2018), Google Scholar (2018), CINAHL (1981-2018), Cochrane Central Register of Controlled Trials (2018), 6 clinical trials registries and conference proceedings (2010-2018). Title searches, data abstraction, and risk of bias assessments were performed in duplicate. We included all published and unpublished, randomized and quasi-randomized trials of IND for procedures in children younger than 19 years of age without language restriction. The methodological quality of studies was evaluated using the Cochrane Collaboration's Risk of Bias tool. The primary outcome was the proportion of participants that were deemed to be adequately sedated for the procedure. Results: Of 661 studies, 18 met inclusion criteria. Trials involved 2128 participants, age 1 month - 14 years (836, 39.3% females), who received IND 1 - 4 mcg/kg either by drops (n = 12), atomizer (n = 4), or both (n = 2). 12 trials were eligible for meta-analysis. 13 trials used validated instruments to assess sedation. All studies except one were associated with low or moderate risk of bias. For painful procedures (IV insertion; laceration repair; dental extraction), the pooled OR (95% CI) for adequate sedation and need for additional analgesia was non-significant [1.19 (0.53, 2.65)] and [2.16 (0.62, 7.49)], respectively (n = 5). For non-painful procedures (diagnostic imaging), the corresponding pooled OR (95% CI) favored IND [3.04 (1.58, 5.82)] and [4.44 (2.11, 9.35)], respectively (n = 7). Time to onset and duration of sedation ranged from 13-31 minutes and 41-91.5 minutes, respectively. For adverse effects, the pooled OR (95% CI) was not significantly different between IND and comparators [0.58 (0.22, 1.55] and there were no serious adverse events. Conclusion: IND at doses 1 to 4 mcg/kg are safe and adequately sedate children undergoing non-painful procedures, although the ease of administration must be weighed against the risk of prolonged sedation. Additional trials with larger sample sizes and greater methodologic rigor are needed for painful emergency department procedures such as laceration repair and IV insertion.

Lapses in care during transition in adult CHD patients lead to increased morbidity and mortality. Previous studies have investigated predictors of poor follow-up in universal healthcare paradigms and select American populations. We studied patients with a wide spectrum of CHD severity within a single American centre to identify factors associated with successful internal transition and maintenance of care. Loss of follow-up was defined as no documented cardiac follow-up for ⩾3 years. Ambulatory cardiology patients aged 16–17 years with CHD were retrospectively enrolled and contacted. A survey assessing demographics, patients’ understanding of their CHD, medical status, and barriers to care was administered. On the basis of chart review of 197 enrolled patients, 74 demonstrated loss of follow-up (37.6%). Of 78 successfully contacted patients, 58 were surveyed, of whom a minority had loss of follow-up (n=16). The status of most patients with loss of follow-up was not known. Maintenance of care was associated with greater complexity of CHD (p<0.01), establishment of care with an adult CHD provider (p<0.001), use of prescription medications (p<0.001), and receipt of education emphasising the importance of long-term cardiac care (p<0.003). Insurance lapses were not associated with loss of follow-up (p=0.08). Transition and maintenance of care was suboptimal even within a single centre. Over one-third of patients did not maintain care. Patients with greater-complexity CHD, need for medications, receipt of transition education, and care provided by adult CHD providers had superior follow-up.

Introduction: In high-income countries, vomiting often impedes oral rehydration therapy, leading to intravenous rehydration fluid administration to children with acute gastroenteritis. Ondansetron administration reduces vomiting and intravenous fluid administration in this population. We evaluated whether ondansetron is similarly effective when employed in Pakistan. Methods: In this 2-hospital, double-blind, placebo-controlled, emergency department-based, randomized trial, we recruited children aged 0·5 to 5·0 years, without dehydration, who had diarrhea and 1 episode of vomiting within 4 hours of arrival. Patients were randomly assigned (1:1), via an internet-based randomization service, using a stratified, variable block randomization scheme, to receive a single dose of oral ondansetron or placebo. The primary endpoint was intravenous rehydration (administration of 20 ml/kg over 4 hours of an isotonic fluid) within 72 hours of randomization. All randomized children were analysed. Results: From July 3, 2014, to January 12, 2017, 626 children were randomized. Intravenous rehydration was provided to 10.8% (34/314) and 10.3% (27/312) of children administered placebo and ondansetron, respectively (OR: 0.946; 95% CI: 0.564, 1.587; P=0.834). A regression model fitted with treatment group and adjusted for antiemetic administration and vomiting frequency in the preceding 24 hours, yielded similar results; OR=0.952; 95% CI: 0.570, 1.589; P=0.850. There was no evidence of interaction between treatment group and age (P=0.974), 3 diarrheal stools in the preceding 24 hours (P=0.983) or 3 vomits in the preceding 24 hours (P=0.554). During the 4-hour study observation period, 24.0% (75/314) and 19.6% (61/312) of children in the placebo and ondansetron groups vomited, respectively; OR: 0.774; 95%CI: 0.528, 1.133; P=0.187. Conclusion: Ondansetron administration did not significantly reduce intravenous rehydration use, suggesting that in children without dehydration, ondansetron administration does not significantly alter the disease course and should not be administered to this group of children.

Top-down biomedical interventions to control schistosomiasis in sub-Saharan Africa have had limited success, primarily because they fail to engage with the social, political, economic and ecological contexts in which they are delivered. Despite the call to foster community engagement and to adapt interventions to local circumstances, programmes have rarely embraced such an approach. This article outlines a community co-designed process, based upon Human-Centered Design, to demonstrate how this approach works in practice. It is based on initial work undertaken by social science researchers, public health practitioners and community members from the Zanzibar Islands, Tanzania, between November 2011 and December 2013. During the process, 32 community members participated in a qualitative and quantitative data-driven workshop where they interpreted data on local infections from S. haematobium and co-designed interventions with the assistance of a facilitator trained in the social sciences. These interventions included the implementation of novel school-based education and training, the identification of relevant safe play activities and events at local schools, the installation of community-designed urinals for boys and girls and the installation of community-designed laundry-washing platforms to reduce exposure to cercariae-contaminated fresh water. It is suggested that the a community co-designed process, drawing from Human-Centered Design principles and techniques, enables the development of more sustainable and effective interventions for the control of schistosomiasis.

Africa is experiencing a rapid increase in adult obesity and associated cardiometabolic diseases (CMDs). The H3Africa AWI-Gen Collaborative Centre was established to examine genomic and environmental factors that influence body composition, body fat distribution and CMD risk, with the aim to provide insights towards effective treatment and intervention strategies. It provides a research platform of over 10 500 participants, 40–60 years old, from Burkina Faso, Ghana, Kenya and South Africa. Following a process that involved community engagement, training of project staff and participant informed consent, participants were administered detailed questionnaires, anthropometric measurements were taken and biospecimens collected. This generated a wealth of demographic, health history, environmental, behavioural and biomarker data. The H3Africa SNP array will be used for genome-wide association studies. AWI-Gen is building capacity to perform large epidemiological, genomic and epigenomic studies across several African counties and strives to become a valuable resource for research collaborations in Africa.

Dengue is regarded as the most important arboviral disease. Although sporadic cases have been reported, serotypes responsible for outbreaks have not been identified from central India over the last 20 years. We investigated two outbreaks of febrile illness, in August and November 2012, from Korea district (Chhattisgarh) and Narsinghpur district (Madhya Pradesh), respectively. Fever and entomological surveys were conducted in the affected regions. Molecular and serological tests were conducted on collected serum samples. Dengue-specific amplicons were sequenced and phylogenetic analyses were performed. In Korea and Narsinghpur districts 37·3% and 59% of cases were positive, respectively, for dengue infection, with adults being the worst affected. RT–PCR confirmed dengue virus serotype 1 genotype III as the aetiology. Ninety-six percent of infections were primary. This is the first time that dengue virus 1 outbreaks have been documented from central India. Introduction of the virus into the population and a conducive mosquitogenic environment favouring increased vector density caused the outbreak. Timely diagnosis and strengthening vector control measures are essential to avoid future outbreaks.

Background.
Controlling tuberculosis (TB) infection among occupationally exposed healthcare workers (HCWs) may be challenging.
Methods.We retrospectively reviewed clinical records of HCWs who were exposed to patients diagnosed with infectious TB at King Abdulaziz Medical City, Riyadh, Saudi Arabia, between 2008 and 2010. The collected data included baseline tuberculin skin test (TST) status, potential predictors of TST positivity, postexposure diagnosis of latent TB infection (LTBI), and postexposure compliance with LTBI therapy.
Results.Thirteen patients were diagnosed with infectious pulmonary TB during the study period. A total of 298 HCWs met our definition for exposure. Exposed HCWs tended to be female (62.9%), non-Saudi (83.9%), nurses (68.6%), or respiratory therapists (24.0%) working in critical care locations (72.8%). Baseline (preemployment) TST documentation existed for 41.3% (123/298). Among those with documented baseline TSTs, 51.2% (63/123) were positive, representing 21.1% (63/298) of all HCWs. Only 48.9% (115/235) of exposed HCWs who had negative or unknown preexposure TST status had their TST tested after exposure. Approximately 46.1% (53/115) of them were diagnosed with postexposure LTBI, and 92.5% (49/53) of them were prescribed LTBI therapy. Among those, 93.9% (46/49) started LTBI therapy; however, 82.6% (38/46) failed to complete the recommended course.
Conclusions.We found low rates of baseline TST documentation and postexposure screening among exposed HCWs. Compliance with initiating postexposure isoniazid prophylaxis among HCWs was fair, but only a small fraction of those who started prophylaxis completed the recommended course of therapy. These findings suggest substantial opportunities to implement administrative measures to enhance LTBI management among HCWs.
