In previously healthy subjects, vulvar ulcers are mostly caused by sexually transmitted microorganisms. Lipschütz's acute vulvar ulceration, first reported in 1912, is a non-sexually acquired condition characterized by sudden onset of a few genital ulcers. We systematically review presentation, underlying causes, and disease duration of Lipschütz's ulceration. A comprehensive source of Excerpta Medica, National Library of Medicine, and Web of Science databases was performed. Reports including cases of apparently previously healthy females affected by Lipschütz's ulceration were selected. A predefined database was used to extract data on demographics, history, clinical and microbiological findings, and treatment.The search disclosed 158 cases. Almost 90% of cases were ≤ 20 years of age and sexually inactive. Lesions were usually one to about three, painful, ≥ 10 mm large, well-delimited, with a fibrinous and necrotic center and a symmetric distribution. Voiding disorders and enlarged inguinal lymph nodes were observed in a large subset of cases. Canker sores were noted in 10% of patients. Lipschütz's vulvar ulceration occurred concomitantly with an infectious disease in 139 cases. Infectious mononucleosis syndrome (N = 40) was the most frequently detected well-defined infection, followed by mycoplasma species infections (N = 11). The disease resolved after ≤ 3 weeks.Conclusions: Lipschütz's ulceration mainly affects both sexually inactive and, less frequently, sexually active subjects ≤ 20 years of age, presents with ≤ 3 vulvar ulcers, resolves without recurrences within 3 weeks and is temporarily associated with an infection, most frequently a flu-like illness or an infectious mononucleosis syndrome. What is Known: • Lipschütz's acute vulvar ulceration is a non-sexually acquired condition, which is characterized by a sudden onset of a few necrotic and painful genital ulcers. • The condition tends to resolve spontaneously and is usually triggered by an infection. What is New: • The condition mainly affects subjects ≤ 20 years of age, tends to resolve within 3 weeks, and is usually temporarily associated with a flu-like illness or an infectious mononucleosis syndrome. • Systemic corticosteroids do not reduce disease duration.

BACKGROUND
The gut fermentation syndrome (GFS), also known as the endogenous alcohol fermentation syndrome or auto brewery syndrome, is a rare and underdiagnosed medical condition where consumed carbohydrates are converted to alcohol by the microbiota in the gastrointestinal or urinary tract. The symptoms of GFS can have severe impact on patients' wellbeing and can have social and legal consequences. Unfortunately, not much is reported about GFS. The aim of this systematic review was to assess the evidence for GFS, causal micro-organisms, diagnostics, and possible treatments.
METHODS
A protocol was developed prior to initiation of the systematic review (PROSPERO 207182). We performed a literature search for clinical studies on 1 September 2020 using PubMed and Embase. We included all clinical studies, including case reports that described the GFS.
RESULTS
In total, 17 case reports were included, consisting of 20 patients diagnosed with GFS. The species that caused the GFS included Klebsiella pneumoniae, Candida albicans, C. glabrata, Saccharomyces cerevisiae, C. intermedia, C. parapsilosis, and C. kefyr.
CONCLUSIONS
GFS is a rare but underdiagnosed disease in daily practice. The disease is mostly reported by Saccharomyces and Candida genera, and some cases were previously treated with antibiotics. Studies in Nonalcoholic Fatty Liver disease suggest a bacterial origin of endogenous alcohol-production, which might also be causal micro-organisms in GFS. Current treatments for GFS include antibiotics, antifungal medication, low carbohydrate diet, and probiotics. There might be a potential role of fecal microbiota transplant in the treatment of GFS.

Meta-Analysis
Despite evidence of health benefits from kefir administration, a systematic review with meta-analysis on bioactive compounds associated with these benefits is still absent in the literature. Kefir is fermented milk resulting from the metabolism of a complex microbiota in symbiosis. Recent researches have investigated the bioactive compounds responsible for the preventive and therapeutic effects attributed to kefir. However, differences in functional potential between industrial and artisanal kefir are still controversial. Firstly, we identified differences in the microbial composition among both types of kefir. Available evidence concerning the action of different bioactive compounds from kefir on health, both from and studies, was subsequently summarized to draw a primary conclusion of the dose and the intervention time for effect, the producer microorganisms, the precursor in the milk, and the action mechanism. Meta-analysis was performed to investigate the statistically significant differences ( < 0.05) between intervention and control and between both types of kefir for each health effect studied. In summary, the bioactive compounds more commonly reported were exopolysaccharides, including kefiran, bioactive peptides, and organic acids, especially lactic acid. Kefir bioactive compounds presented antimicrobial, anticancer, and immune-modulatory activities corroborated by the meta-analysis. However, clinical evidence is urgently needed to strengthen the practical applicability of these bioactive compounds. The mechanisms of their action were diverse, indicating that they can act by different signaling pathways. Still, industrial and artisanal kefir may differ regarding functional potential-OR of 8.56 (95% CI: 2.27-32.21, ≤ .001)-according to the observed health effect, which can be associated with differences in the microbial composition between both types of kefir.

The human gut microbiota are the microorganisms (generally bacteria and archaea) that live in the digestive tracts of humans. Due to their numerous functions, the gut microbiota can be considered a virtual organ of the body, playing a pivotal role in health maintenance. Dietary habits contribute to gut microbiota composition, and evidence from observational and intervention studies suggest that vegan diets may promote health, potentially through affecting the diverse ecosystem of beneficial bacteria in the gut. A systematic literature search was conducted on PubMed and Scopus to identify studies investigating the microbiota composition in vegans. Vegans are defined as people excluding food products that are derived from animals from their diet. Nine observational studies were identified. The main outcome of the systematic review was an increase in Bacteroidetes on the phylum level and a higher abundance of on the genus level. In conclusion, the present systematic literature review highlighted some benefits of a vegan diet but also demonstrated the complexity of evaluating results from gut microbiota research. The available evidence only consisted of cross-sectional studies, therefore suggesting the need for well-designed randomised controlled trials. Furthermore, the quality assessment of the studies included in the review suggested a lack of standardised and validated methods for participant selection as well as for faecal sampling and faecal analysis.

The human microbiome plays a crucial role in determining the health status of every human being, and the microbiome of the genital tract can affect the fertility potential before and during assisted reproductive treatments (ARTs). This review aims to identify and appraise studies investigating the correlation of genital microbiome to infertility. Publications up to February 2021 were identified by searching the electronic databases PubMed/MEDLINE, Scopus and Embase and bibliographies. Only full-text original research articles written in English were considered eligible for analysis, whereas reviews, editorials, opinions or letters, case studies, conference papers, and abstracts were excluded. Twenty-six articles were identified. The oldest studies adopted the exclusive culture-based technique, while in recent years PCR and RNA sequencing based on 16S rRNA were the most used technique. Regardless of the anatomical site under investigation, the -dominated flora seems to play a pivotal role in determining fertility, and in particular showed a central role. Nonetheless, the presence of pathogens in the genital tract, such as , , species, and Gram-negative stains microorganism, affected fertility also in case of asymptomatic bacterial vaginosis (BV). We failed to identify descriptive or comparative studies regarding tubal microbiome. The microbiome of the genital tract plays a pivotal role in fertility, also in case of ARTs. The standardization of the sampling methods and investigations approaches is warranted to stratify the fertility potential and its subsequent treatment. Prospective tubal microbiome studies are warranted.

Ivermectin proposes many potentials effects to treat a range of diseases, with its antimicrobial, antiviral, and anti-cancer properties as a wonder drug. It is highly effective against many microorganisms including some viruses. In this comprehensive systematic review, antiviral effects of ivermectin are summarized including in vitro and in vivo studies over the past 50 years. Several studies reported antiviral effects of ivermectin on RNA viruses such as Zika, dengue, yellow fever, West Nile, Hendra, Newcastle, Venezuelan equine encephalitis, chikungunya, Semliki Forest, Sindbis, Avian influenza A, Porcine Reproductive and Respiratory Syndrome, Human immunodeficiency virus type 1, and severe acute respiratory syndrome coronavirus 2. Furthermore, there are some studies showing antiviral effects of ivermectin against DNA viruses such as Equine herpes type 1, BK polyomavirus, pseudorabies, porcine circovirus 2, and bovine herpesvirus 1. Ivermectin plays a role in several biological mechanisms, therefore it could serve as a potential candidate in the treatment of a wide range of viruses including COVID-19 as well as other types of positive-sense single-stranded RNA viruses. In vivo studies of animal models revealed a broad range of antiviral effects of ivermectin, however, clinical trials are necessary to appraise the potential efficacy of ivermectin in clinical setting.

Hand hygiene is of utmost importance as it may be contaminated easily from direct contact with airborne microorganism droplets from coughs and sneezes. Particularly in situations like pandemic outbreak, it is crucial to interrupt the transmission chain of the virus by the practice of proper hand sanitization. It can be achieved with contact isolation and strict infection control tool like maintaining good hand hygiene in hospital settings and in public. The success of the hand sanitization solely depends on the use of effective hand disinfecting agents formulated in various types and forms such as antimicrobial soaps, water-based or alcohol-based hand sanitizer, with the latter being widely used in hospital settings. To date, most of the effective hand sanitizer products are alcohol-based formulations containing 62%-95% of alcohol as it can denature the proteins of microbes and the ability to inactivate viruses. This systematic review correlated with the data available in Pubmed, and it will investigate the range of available hand sanitizers and their effectiveness as well as the formulation aspects, adverse effects, and recommendations to enhance the formulation efficiency and safety. Further, this article highlights the efficacy of alcohol-based hand sanitizer against the coronavirus.

Meta-Analysis Review
BACKGROUND
Functional abdominal pain is pain occurring in the abdomen that cannot be fully explained by another medical condition and is common in children. It has been hypothesised that the use of micro-organisms, such as probiotics and synbiotics (a mixture of probiotics and prebiotics), might change the composition of bacterial colonies in the bowel and reduce inflammation, as well as promote normal gut physiology and reduce functional symptoms.
OBJECTIVES
To assess the efficacy and safety of probiotics in the treatment of functional abdominal pain disorders in children.
SEARCH METHODS
We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL) and two clinical trials registers from inception to October 2021.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compare probiotic preparations (including synbiotics) to placebo, no treatment or any other interventional preparation in patients aged between 4 and 18 years of age with a diagnosis of functional abdominal pain disorder according to the Rome II, Rome III or Rome IV criteria.
DATA COLLECTION AND ANALYSIS
The primary outcomes were treatment success as defined by the primary studies, complete resolution of pain, improvement in the severity of pain and improvement in the frequency of pain. Secondary outcomes included serious adverse events, withdrawal due to adverse events, adverse events, school performance or change in school performance or attendance, social and psychological functioning or change in social and psychological functioning, and quality of life or change in quality life measured using any validated scoring tool. For dichotomous outcomes, we calculated the risk ratio (RR) and corresponding 95% confidence interval (95% CI). For continuous outcomes, we calculated the mean difference (MD) and corresponding 95% CI.
MAIN RESULTS
We included 18 RCTs assessing the effectiveness of probiotics and synbiotics in reducing the severity and frequency of pain, involving a total of 1309 patients. Probiotics may achieve more treatment success when compared with placebo at the end of the treatment, with 50% success in the probiotic group versus 33% success in the placebo group (RR 1.57, 95% CI 1.05 to 2.36; 554 participants; 6 studies; I = 70%; low-certainty evidence). It is not clear whether probiotics are more effective than placebo for complete resolution of pain, with 42% success in the probiotic group versus 27% success in the placebo group (RR 1.55, 95% CI 0.94 to 2.56; 460 participants; 6 studies; I = 70%; very low-certainty evidence). We judged the evidence to be of very low certainty due to high inconsistency and risk of bias. We were unable to draw meaningful conclusions from our meta-analyses of the pain severity and pain frequency outcomes due to very high unexplained heterogeneity leading to very low-certainty evidence. None of the included studies reported serious adverse events. Meta-analysis showed no difference in withdrawals due to adverse events between probiotics (1/275) and placebo (1/269) (RR 1.00, 95% CI 0.07 to 15.12). The results were identical for the total patients with any reported adverse event outcome. However, these results are of very low certainty due to imprecision from the very low numbers of events and risk of bias. Synbiotics may result in more treatment success at study end when compared with placebo, with 47% success in the probiotic group versus 35% success in the placebo group (RR 1.34, 95% CI 1.03 to 1.74; 310 participants; 4 studies; I = 0%; low certainty). One study used Bifidobacterium coagulans/fructo-oligosaccharide, one used Bifidobacterium lactis/inulin, one used Lactobacillus rhamnosus GG/inulin and in one study this was not stated). Synbiotics may result in little difference in complete resolution of pain at study end when compared with placebo, with 52% success in the probiotic group versus 32% success in the placebo group (RR 1.65, 95% CI 0.97 to 2.81; 131 participants; 2 studies; I = 18%; low-certainty evidence). We were unable to draw meaningful conclusions from our meta-analyses of pain severity or frequency of pain due to very high unexplained heterogeneity leading to very low-certainty evidence. None of the included studies reported serious adverse events. Meta-analysis showed little to no difference in withdrawals due to adverse events between synbiotics (8/155) and placebo (1/147) (RR 4.58, 95% CI 0.80 to 26.19), or in any reported adverse events (3/96 versus 1/93, RR 2.88, 95% CI 0.32 to 25.92). These results are of very low certainty due to imprecision from the very low numbers of events and risk of bias. There were insufficient data to analyse by subgroups of specific functional abdominal pain syndrome (irritable bowel syndrome, functional dyspepsia, abdominal migraine, functional abdominal pain - not otherwise specified) or by specific strain of probiotic. There was insufficient evidence on school performance or change in school performance/attendance, social and psychological functioning, or quality of life to draw conclusions about the effects of probiotics or synbiotics on these outcomes.
AUTHORS' CONCLUSIONS
The results from this review demonstrate that probiotics and synbiotics may be more efficacious than placebo in achieving treatment success, but the evidence is of low certainty. The evidence demonstrates little to no difference between probiotics or synbiotics and placebo in complete resolution of pain. We were unable to draw meaningful conclusions about the impact of probiotics or synbiotics on the frequency and severity of pain as the evidence was all of very low certainty due to significant unexplained heterogeneity or imprecision. There were no reported cases of serious adverse events when using probiotics or synbiotics amongst the included studies, although a review of RCTs may not be the best context to assess long-term safety. The available evidence on adverse effects was of very low certainty and no conclusions could be made in this review. Safety will always be a priority in paediatric populations when considering any treatment. Reporting of all adverse events, adverse events needing withdrawal, serious adverse events and, particularly, long-term safety outcomes are vital to meaningfully move forward the evidence base in this field. Further targeted and appropriately designed RCTs are needed to address the gaps in the evidence base. In particular, appropriate powering of studies to confirm the safety of specific strains not yet investigated and studies to investigate long-term follow-up of patients are both warranted.

Meta-Analysis
BACKGROUND
Antibiotic-associated diarrhea (AAD) is diarrhea associated with consuming antibiotics that cannot be explained by other causes. AAD prolongs admission time and increases mortality and financial costs. Elderly individuals are more prone to receive antibiotic treatment and develop AAD. The finding that living probiotic microorganisms decrease AAD incidence in adults (<65 years) has been clarified. However, it is controversial among elderly individuals.
METHODS
We aimed to explore whether probiotics could prevent AAD in elderly individuals. We searched three electronic databases (PubMed, EMBASE, and The Cochrane Library), and two reviewers independently screened and assessed the studies. RevMan5.4 software was used to perform a meta-analysis according to the PRISMA guidelines.
RESULTS
Eight RCTs of 4691 participants were included. We excluded two large studies because probiotics were used 48 hours after the first dose of antibiotics, and there was no effect. Subgroup analysis of 6 RCTs showed that probiotics given within two days of antibiotic treatment produced a lower AAD prevalence rate in elderly individuals.
CONCLUSION
We recommend that elderly individuals could be routinely distributed probiotics to prevent AAD development when receiving antibiotic treatment.

Meta-Analysis
BACKGROUND
Chronic suppurative otitis media (CSOM), sometimes referred to as chronic otitis media (COM), is a chronic inflammation and often polymicrobial infection (involving more than one micro-organism) of the middle ear and mastoid cavity, characterised by ear discharge (otorrhoea) through a perforated tympanic membrane. The predominant symptoms of CSOM are ear discharge and hearing loss. Topical antibiotics, the most common treatment for CSOM, act to kill or inhibit the growth of micro-organisms that may be responsible for the infection. Antibiotics can be used alone or in addition to other treatments for CSOM, such as antiseptics or ear cleaning (aural toileting).
OBJECTIVES
To assess the effects of topical antibiotics (without steroids) for people with CSOM.
SEARCH METHODS
The Cochrane ENT Information Specialist searched the Cochrane ENT Register; Central Register of Controlled Trials (CENTRAL via the Cochrane Register of Studies); Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 1 April 2019.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) with at least a one-week follow-up involving participants (adults and children) who had chronic ear discharge of unknown cause or CSOM, where the ear discharge had continued for more than two weeks. The interventions were any single, or combination of, topical antibiotic agent(s) of any class, applied directly into the ear canal as ear drops, powders or irrigations, or as part of an aural toileting procedure. The two main comparisons were topical antibiotic compared to a) placebo or no intervention and b) another topical antibiotic (e.g. topical antibiotic A versus topical antibiotic B). Within each comparison we separated studies where both groups of participants had received topical antibiotic a) alone or with aural toileting and b) on top of background treatment (such as systemic antibiotics).
DATA COLLECTION AND ANALYSIS
We used the standard Cochrane methodological procedures. We used GRADE to assess the certainty of the evidence for each outcome. Our primary outcomes were: resolution of ear discharge or 'dry ear' (whether otoscopically confirmed or not), measured at between one week and up to two weeks, two weeks to up to four weeks and after four weeks; health-related quality of life using a validated instrument; ear pain (otalgia) or discomfort or local irritation. Secondary outcomes included hearing, serious complications and ototoxicity measured in several ways.
MAIN RESULTS
We included 17 studies with a total of 2198 participants. Twelve studies reported the sample size in terms of participants (not ears); these had a total of 1797 participants. The remaining five studies reported both the number of participants and ears, representing 401 participants, or 510 ears. A: Topical antibiotics versus placebo or no treatment (with aural toilet in both arms and no other background treatment) One small study compared a topical antibiotic (ciprofloxacin) with placebo (saline). All participants received aural toilet. Although ciprofloxacin was better than saline in terms of resolution of discharge at one to two weeks: 84% versus 12% (risk ratio (RR) 6.74, 95% confidence interval (CI) 1.82 to 24.99; 35 participants, very low-certainty evidence), the very low certainty of the evidence means that it is very uncertain whether or not one intervention is better or worse than the other. The study authors reported that "no medical side-effects and worsening of audiological measurements related to this topical medication were detected" (very low-certainty evidence). B: Topical antibiotics versus placebo or no treatment (with use of oral antibiotics in both arms) Four studies compared topical ciprofloxacin to no treatment (three studies; 190 participants) or topical ceftizoxime to no treatment (one study; 248 participants). In each study all participants received the same antibiotic systemically (oral ciprofloxacin, injected ceftizoxime). In at least one study all participants received aural toilet. Useable data were only available from the first three studies; ciprofloxacin was better than no treatment, resolution of discharge occurring in 88.2% versus 60% at one to two weeks (RR 1.47, 95% CI 1.20 to 1.80; 2 studies, 150 participants; low-certainty evidence). None of the studies reported ear pain or discomfort/local irritation. C: Comparisons of different topical antibiotics The certainty of evidence for all outcomes in these comparisons is very low. Quinolones versus aminoglycosides Seven studies compared an aminoglycoside (gentamicin, neomycin or tobramycin) with ciprofloxacin (734 participants) or ofloxacin (214 participants). Whilst resolution of discharge at one to two weeks was higher in the quinolones group the very low certainty of the evidence means that it is very uncertain whether or not one intervention is better or worse than the other (RR 1.95, 95% CI 0.88 to 4.29; 6 studies, 694 participants). One study measured ear pain and reported no difference between the groups. Quinolones versus aminoglycosides/polymyxin B combination ±gramicidin We identified three studies but data on our primary outcome were only available in one study. Comparing ciprofloxacin to a neomycin/polymyxin B/gramicidin combination, for an unknown treatment duration (likely four weeks), ciprofloxacin was better (RR 1.12, 95% CI 1.03 to 1.22, 186 participants). A "few" patients experienced local irritation upon the first instillation of topical treatment (numbers/groups not stated). Others Other studies examined topical gentamicin versus a trimethoprim/sulphacetamide/polymixin B combination (91 participants) and rifampicin versus chloramphenicol (160 participants). Limited data were available and the findings were very uncertain.
AUTHORS' CONCLUSIONS
We are uncertain about the effectiveness of topical antibiotics in improving resolution of ear discharge in patients with CSOM because of the limited amount of low-quality evidence available. However, amongst this uncertainty there is some evidence to suggest that the use of topical antibiotics may be effective when compared to placebo, or when used in addition to a systemic antibiotic. There is also uncertainty about the relative effectiveness of different types of antibiotics; it is not possible to determine with any certainty whether or not quinolones are better or worse than aminoglycosides. These two groups of compounds have different adverse effect profiles, but there is insufficient evidence from the included studies to make any comment about these. In general, adverse effects were poorly reported.
