Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by behavioral features that appear early in life. Although studies have shown that atypical brain functional and structural connectivity are associated with these behavioral traits, the occurrence and initial alterations of brain networks have not been fully investigated. The current study aimed to map early brain network efficiency and information transferring in infants at elevated likelihood (EL) compared to infants at typical likelihood (TL) for ASD in the first year of life. This study used a resting-state functional near-infrared spectroscopy (fNIRS) approach to obtain the length and strength of functional connections in the frontal and temporal areas in 45 5-month-old and 38 10-month-old infants. Modular organization and small-world properties were detected in both EL and TL infants at 5 and 10 months. In 5-month-old EL infants, local and nodal efficiency were significantly greater than age-matched TL infants, indicating overgrown local connections. Furthermore, we used a support vector machine (SVM) model to classify infants with or without EL based on the obtained global properties of the network, achieving an accuracy of 77.6%. These results suggest that infants with EL for ASD exhibit inefficiencies in the organization of brain networks during the first year of life.

The impact of COVID-19 measures on parent-reported restricted and repetitive behaviours in pre-school children with autism. Heliyon 2022; 8:e09727. [PMID: 35720765 PMCID: PMC9188681 DOI: 10.1016/j.heliyon.2022.e09727] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/22/2022] [Accepted: 06/09/2022] [Indexed: 11/18/2022] Open
Abstract
Background COVID-19 restrictive measures have had a considerable impact on daily life routines, which may be especially challenging for families of children with autism. In pre-schoolers with autism, it is likely that the disruption of routines mainly impacts the presence of restrictive and repetitive behaviours (RRBs). Furthermore, influence of comorbid conditions, secondary behavioural difficulties and home environment characteristics on RRBs was explored. Method A cross-sectional online survey design was used to collect parent-report data on 254 children with autism (2.5–6 years) during lockdown in the early months of the pandemic. RRBs were assessed using the Repetitive Behaviour Scale-Revised (RBS-R). Results Parents reported a significant increase in stereotypic, self-injurious, compulsive and ritualistic behaviour, and restricted interests after implementation of COVID-19 restrictions. The presence of a co-occurring condition, such as language impairments or intellectual disability, was associated with more self-injurious and stereotypic behaviour. However, there was no effect of home environment on RRBs. Further, most children showed increases in internalising and/or externalising behaviour. Increased inattentive behaviour was associated with more ritualistic and stereotypic behaviour, and restricted interests. Decreases in hyperactivity were related to more restricted interests. Importantly, in a subset of children, parents reported less behavioural difficulties during the lockdown. Conclusions Findings highlight the importance of flexible implementation and continuity of care for pre-schoolers with autism and support for parents. Further follow-up of children with autism and RRBs, and co-occurring behavioural difficulties is needed and could enhance our understanding of the long-term effects associated with sudden restrictive measures to daily routines.

Abstract
Play of younger siblings of children with autism spectrum disorder (ASD) (siblings; n = 44), very preterm children (preterms; n = 44), and children at typical likelihood for ASD (n = 36) was observed at 24 months. Children with ASD and atypical development engaged less in spontaneous (pre-)symbolic play than typically developing children. Total duration of spontaneous and elicited (pre-)symbolic play was associated with later ASD traits in siblings. However, no association between most play variables and ASD traits was found in preterms. This suggests possible different ASD-trajectories between siblings and preterms. Thus, spontaneous (pre-)symbolic play may be indicative of developmental challenges across several populations, and results highlight the need to move beyond studying only siblings in order to broaden our understanding of ASD.

Abstract
Liver abscess is a rare condition. There are multiple etiologies and mortality linked to the infections or local complications is high. The rapid diagnosis and the implementation of an adequate and effective treatment are essential to allow healing without sequels. We report the case of a monofocal bacterial hepatic abscess in a 61-year-old patient with an iatrogenic origin. A review of the literature is proposed in order to address the incidence, the different microorganisms, the different etiologies and the different possibilities of treatment. It should be noted that mycotic abscess, which is extremely rare outside the immunocompromised patient, will not be discussed in this article.

Abstract
The use of the emergency department (ED) by human immunodeficiency virus (HIV)-infected adults undergoes an evolution following the introduction of antiretroviral therapy (ART). Improving our knowledge about ED use characteristics will contribute to a correct diagnosis and therapeutic approach in this patient group, at the moment they are discharged from the ED. We conducted a one-year retrospective study on characteristics of ED use involving 1026 patients living with HIV. The majority of them was treated with antiretroviral therapy (95 %) and had a viral load lower than 50 copies (73.6 %). Among them, 117 patients (11.8 %) were admitted at least once to the ED. The most common ED discharge diagnoses were related to trauma (30 %). This study shows that the great majority of diagnoses were not related to infectious diseases (6.3 %, of which half were HIV-related). One hypothesis to explain these results would be that HIV-positive adults in this study had excellent antiretroviral coverage and were well controlled in terms of HIV.

Abstract
Cases of CMV proctitis are frequently reported in immunocompromised patients. However, some cases of CMV proctitis are linked to a CMV primary infection and to unprotected anal intercourse in immunocompetent patients. The most common symptom is bloody diarrhea (hemorrhagic colitis). The endoscopic exam can present in distincts forms. The diagnostic is based on a set of clinical, biological, endoscopic and histological arguments. The prognosis of the disease is favorable. The treatment is supportive. A research on other sexually transmitted diseases must be conducted.

Abstract
Osteoarticular or skeletal tuberculosis is a clinical manifestation of extrapulmonary tuberculosis, occurring during the lympho-hematogenous spread of Mycobacterium tuberculosis from a pulmonary primary infection or reactivation of latent infection, years or even decades after the initial infection. Bone and joint tuberculosis is a rare disease with non-specific symptoms and radiological characteristics, often delaying diagnosis for more than a year after clinical onset. First-line hospital departments should develop a clinical suspicion when confronted with a subacute inflammatory bone or joint pathology in patients with underlying comorbidities, especially when coming from tuberculosis-endemic countries. We report a clinical case characterized by lumbar and pelvic abscesses, before addressing in detail the different types of skeletal involvement related to tuberculosis, through a review of the literature.

Abstract
Lyme disease is a complex pathology due to an infection by a spirochaete from the genus Borrelia. This infection results from a tick bite lasting more than 24 hours. Signs and symptoms are numerous and are usually classified in three stages: early localized disease, early disseminated disease and late disease. The skin, the heart, the nervous system and the joints are mostly concerned. It is important to distinguish the clinical manifestations of the disease from those that are sometimes associated with it but with no scientific evidence. The purpose of this article is to insist on which signs and symptoms can be related to the disease and on those that usually are not. Diagnostic methods and treatments are also discussed.

Abstract
We present a case of nephrotic syndrome in a 38-year-old man of Ivorian origin. In the search of the cause of his illness an infection with Plasmodium malariae (P. malariae) was diagnosed by serology and by microscopy of a Giemsa thin blood smear which revealed rare gametocytes of P. malariae. Proteinuria significantly diminished within three months after antimalarial treatment. Antibodies against Schistosoma were detected as well. Examination of kidney biopsy revealed a discrete mesangioproliferative glomerulonephritis. This case highlights that a thorough history-taking may be essential and that infectious diseases should be included in the differential diagnostic thinking process when a nephrotic syndrome is diagnosed.

Abstract
Metastatic tuberculous abcess or tuberculous gumma is a rare form of cutaneous tuberculosis resulting from haematogenous spread from a non-cutaneous tuberculous focus. A 26-year old patient of Pakistani origin presented at our clinic with an abcess on his right thigh that had slowly grown over a period of two months to a total size of 30 cm. Based on clinical findings, microbiology, CT thigh and CT chest, our patient was diagnosed with a tuberculous abcess and cervico-mediastinal tuberculous lymphadenitis. Antituberculosis drugs were initiated. Cutaneous tuberculosis should be included in the differential diagnosis of chronic cutaneous abcesses, especially in patients from tuberculosis endemic nations.

Abstract
People have a growing preference for fresh, healthy, palatable and nutritious meals and drinks. However, as food deterioration is a constant threat along the entire food chain, food preservation remains as necessary now as in the past. High pressure processing is one of the emerging technologies being studied as an alternative to the classical pasteurization and sterilization treatments of food. Samples of fried minced pork meat were inoculated with strains of Streptococcus faecalis and with sporulating microorganisms like Bacillus subtilis and stearothermophilus. The samples were subjected to several combined temperature-high pressure treatments predicted by the mathematical model applied in Response Surface Methodology. Using the "Box-Behnken" concept, the number of tests for a whole area of pressure-temperature-time-combinations (pressure variation: 50-400 MPa, temperature variation 20-80°C, time variation 1-60 min) could be limited to 15. In the center point of the model, the experimental combination was performed in triple to estimate the experimental variance. All the tests were executed in a randomized order to exclude the disturbing effect of environmental factors. Microbial analysis revealed for each microorganism an important reduction in total plate count, demonstrating a superior pressure resistance of the sporulating microorganisms in comparison with the most pressure resistant vegetative species Streptococcus faecalis. The effect of the medium composition could be neglected, showing little protective effect of, e.g. the fat fraction as seen in heat preservation techniques.

Abstract
There is a growing group of HIV-seropositive patients at risk for chronic lung disease due to their life style and age. The interaction between certain antiretroviral drugs and corticosteroid inhalation therapy is potentially dangerous but often unrecognised. We present three cases from our HIV-clinic of whom two developed full blown Cushing's syndrome over a short period of time and one presented with asymptomatic hypocortisolaemia due to serious drug interactions between HIV-drugs and inhaled corticosteroids. General practitioners, HIV and chest physicians should all be aware of this potentially life-threatening interaction and the combination of those products should be avoided where possible.

Abstract
We describe the case of a 14-year-old boy of Turkish origin, presenting with anaphylactic shock after a minor abdominal trauma. Further investigations revealed a hepatic Echinococcal cyst without evidence of rupture. Anti-helminthic therapy was administered. Because of aggravating symptoms and recurrent anaphylaxis, surgical excision was performed. Intra-operative, a rupture into the biliary tree was seen. After surgery, the anaphylactic symptoms disappeared and the patient recovered. This case-report supports the fact that anaphylactic shock can be the only presentation of a hydatid cyst. Microscopic spillage can possibly be sufficient to cause major anaphylaxis.

Abstract
We describe a 55-year-old bisexual Belgian man with a multi-drug resistant HIV infection who developed an Immune Reconstitution Inflammatory Syndrome (IRIS) presenting as a mucocele of the frontal sinus, one year after starting a new effective darunavir containing antiretroviral treatment regimen. His CD4+ lymphocyte count had increased from 3 cells/mm3 prior to the start of the latter treatment to 196 cells/mm3 just before he developed the IRIS phenomenon. IRIS is a paradoxical clinical deterioration during highly active antiretroviral treatment (HAART), due to an exaggerated immune-inflammatory reaction. With the increasing numbers of persons living with HIV infection and the increased use of HAART it is expected that in the future more otolaryngological manifestations of IRIS will be detected.

Abstract
HIV and AIDS, tuberculosis, and malaria, besides presenting a large mortality and morbidity burden in developing countries, are also responsible for poor economic development. In the past international agencies devoted resources and efforts to control malaria and other diseases without taking into account health-system performance and sustainability. Even assuming that the Global Fund to Fight AIDS, Tuberculosis, and Malaria (GFATM)--a recent international initiative--would provide the necessary funds, a poorly performing health-care system will not be able to use these funds optimally. Moreover, even if all interventions are cost-effective, their impact on mortality and morbidity will only be marginal if access to proper care is not guaranteed. It is the responsibility of scientists and health managers to highlight to donor agencies the importance of an accessible and well functioning health-care system at all levels for the control of specific diseases.
