Stay-at-home orders, physical distancing, face masks and other non-pharmaceutical interventions (NPIs) do not only impact COVID-19, but also the dynamics of various other infectious diseases. Bronchiolitis is a clinically diagnosed viral infection of the lower respiratory tract, and causes a yearly seasonal wave of admissions in paediatric wards worldwide. We counted 92,5% less bronchiolitis hospitalisations in Antwerp before the expected end of the peak this year (of which only 1 RSV positive), as compared to the last 3 years. Furthermore, there was a >99% reduction in the number of registered RSV cases in Belgium.Conslusion: The 2020 winter bronchiolitis peak is hitherto nonexistent, but we fear a 'delayed' spring/summer bronchiolitis peak when most NPIs will be relaxed and pre-pandemic life restarts.

Objective To investigate the accuracy of transvaginal sonography (TVS) and contrast-enhanced magnetic resonance-colonography (CE-MR-C) for the presurgical assessment of deep infiltrating endometriosis (DIE). Methods

Scarce evidence on the effectiveness of hysteroscopic surgery in subfertile women with polyps, fibroids, septate uterus or intrauterine adhesions indicates a potential benefit. More randomized controlled trials are needed before widespread use of hysteroscopic surgery in the general subfertile population can be justified.

In everyday clinical practice, it is not always clear if and when exactly in the fertility work-up a diagnostic laparoscopy should be offered. The aim of this review is to analyse the available evidence with respect to alternative diagnostic methods for detecting tuboperitoneal infertility and with respect to the position of diagnostic laparoscopy in women with infertility. A literature search of the National Library of Medicine and the National Institutes of Health (PubMed) was performed using the key words 'diagnostic laparoscopy and infertility'. The study methodology was carefully considered in an effort to present conclusions preferably based on randomized controlled trials (RCTs). The routine use of diagnostic laparoscopy for the evaluation of all cases of female infertility is currently under debate. According to data published in retrospective non-controlled studies, diagnostic laparoscopy after several failed cycles of ovulation induction enables the detection of a significant proportion of pelvic pathology amenable to treatment. A Cochrane review has shown that laparoscopic ovarian diathermy in clomiphene-resistant polycystic ovarian syndrome is at least as effective as gonadotrophin treatment, and results in a lower multiple pregnancy rate. The role of laparoscopy before the start of treatment with intrauterine insemination is controversial, according to one RCT. In women with bilateral ultrasonically visible hydrosalpinges, two RCTs have demonstrated increased implantation and pregnancy rates in IVF cycles after salpingectomy. Although RCTs which have studied the benefit of laparoscopic surgery in moderate or severe endometriosis are still lacking, its value has generally been accepted. In conclusion, some specific clinical settings, solid evidence is available to recommend the use of diagnostic laparoscopy in current fertility practice. There is however a need for more RCTs to answer remaining questions regarding its value in the diagnosis and treatment of some patients with infertility.

New insights into the complex and fine-regulated inflammatory mechanisms involved in the endometrium reveal multiple facets to the problem of endometrial inflammation. However, the entity termed chronic endometritis is to date restricted to infectious etiology and managed with antibiotics. Conversely, the concept of impaired inflammatory state of the endometrium (IISE) provides a more global approach to defective endometrial inflammation, considering both infectious and non-infectious etiology. A non-systematic review was done through a search on MEDLINE, EMBASE, Global Health, The Cochrane Library, Health Technology Assessment Database and Web of Science, research registers. Pertinent original and review articles, published in English or French until December 31, 2019, were selected. A compelling body of evidence demonstrates transient, repeated and persistent IISE to be a major factor of most problematic disorders in obstetrics/gynecology, such as endometrial polyps, unexplained infertility, miscarriage, placenta-related pathology and endometrial cancer. When scheduled accordingly, hysteroscopy can play a key role in the IISE assessment. Robust data suggests the pertinence of minimal-effective anti-inflammatory regimens for therapeutic IISE targeting. This review provides a comprehensive update on the multiple facets of inflammation in the endometrial physiology and pathology. Further research is needed to improve classification, diagnosis and treatment of IISE.
