Different subsets of asthma patients may be recognized according to the exposure trigger and the frequency and severity of clinical signs and symptoms. Regarding the exposure trigger, generally asthma can be classified as allergic (or atopic) and nonallergic (or nonatopic). Allergic and nonallergic asthma are distinguished by the presence or absence of clinical allergic reaction and in vitro IgE response to specific aeroallergens. The mechanisms of allergic asthma have been extensively studied with major advances in the last two decades. Nonallergic asthma is characterized by its apparent independence from allergen exposure and sensitization and a higher degree of severity, but little is known regarding the underlying mechanisms. Clinically, allergic and nonallergic asthma are virtually indistinguishable in exacerbations, although exacerbation following allergen exposure is typical of allergic asthma. Although they both show several distinct clinical phenotypes and different biomarkers, there are no ideal biomarkers to stratify asthma phenotypes and guide therapy in clinical practice. Nevertheless, some biomarkers may be helpful to select subsets of atopic patients which might benefit from biologic agents, such as omalizumab. Patients with severe asthma, uncontrolled besides optimal treatment, notwithstanding nonatopic, may also benefit from omalizumab therapy, although currently there are no randomized double-blind placebo controlled clinical trials to support this suggestion. However, omalizumab discontinuation according to each patient’s response to therapy and pharmacoeconomical analysis are questions that remain to be answered.

Treatment with rimantadine of influenza in children and the potential development of resistance in clinical isolates associated with therapy have not been previously studied. We compared rimantadine to acetaminophen therapy in a controlled, double-blind study of 91 children with influenza-like illness. Of 69 children with proven influenza A/H3N2 infection, 37 received rimantadine and 32 received acetaminophen for five days. Children receiving rimantadine showed significantly greater reduction in fever and improvement in daily scores for symptoms and severity of illness during the first three days. Viral shedding also diminished significantly during the first two days but subsequently increased such that by days 6 and 7 the proportion of children shedding virus, as well as the quantity of virus shed, was significantly greater in the rimantadine group. During the seven-day study, of the 22 children in the rimantadine group with serial isolates tested, ten (45.5%) had resistant isolates compared with two (12.5%) of those with serial isolates in the acetaminophen group (P < .03). Thus, of the total 37 children in the rimantadine group, 27% were found to have resistant isolated compared with 6% in the total group receiving acetaminophen (P < .04). Furthermore, the mean inhibitory concentration of rimantadine increased with time in the rimantadine group (r = .4, P = .002) but not in the acetaminophen group. Rimantadine therapy, thus, appears to be significantly more effective than acetaminophen in ameliorating the clinical signs and symptoms of influenza in children. Treatment with rimantadine was also associated with increased viral shedding after the medication was discontinued and with the development of resistance in the clinical isolates, the significance of which is unknown.

Recurrent vulvovaginal candidosis (RVVC) represents a major health problem that significantly affects a patient’s quality of life (QoL). This infection presents with a plethora of clinical manifestation, and this is the first study that carries out a cluster analysis of these signs and symptoms (SS). The goals are to evaluate the distribution of species causing RVVC, their in-vitro susceptibility to antifungals, and the patient’s QoL. Additionally, the clinical characteristics are analyzed using cluster analysis. Prospective analysis of data was performed for women diagnosed with RVVC in the period from January 2016 to December 2019 based on the analysis of data from a single-center’s records. The standard mycological methods and antifungal susceptibility testing were done. Clinical characteristics and QoL were examined by appropriate questions. The cluster analysis was used to identify clusters of SS. A total of 320 women were diagnosed. The dominant species was Candida (C.) albicans. Non-albicans Candida (NAC) yeast was found in 24.4%, and the most common was C. glabrata. Interestingly, Saccharomyces (S.) cerevisiae was detected in 2%. All of the isolated species, except C. parapsilosis and C. kefyr, demonstrated reduced susceptibility to antifungals. We confirmed the emergence of the NAC species and S. cerevisiae with reduced susceptibility to antifungals. Cluster analysis represented by a dendrogram revealed three SS clusters: irritation, uncommon, and discharge, but further studies are needed to examine the relationship between clusters, Candida strains, and outcomes.

Chalcones are among the leading bioactive flavonoids with a therapeutic potential implicated to an array of bioactivities investigated by a series of preclinical and clinical studies. In this article, different scientific databases were searched to retrieve studies depicting the biological activities of chalcones and their derivatives. This review comprehensively describes preclinical studies on chalcones and their derivatives describing their immense significance as antidiabetic, anticancer, anti-inflammatory, antimicrobial, antioxidant, antiparasitic, psychoactive, and neuroprotective agents. Besides, clinical trials revealed their use in the treatment of chronic venous insufficiency, skin conditions, and cancer. Bioavailability studies on chalcones and derivatives indicate possible hindrance and improvement in relation to its nutraceutical and pharmaceutical applications. Multifaceted and complex underlying mechanisms of chalcone actions demonstrated their ability to modulate a number of cancer cell lines, to inhibit a number of pathological microorganisms and parasites, and to control a number of signaling molecules and cascades related to disease modification. Clinical studies on chalcones revealed general absence of adverse effects besides reducing the clinical signs and symptoms with decent bioavailability. Further studies are needed to elucidate their structure activity, toxicity concerns, cellular basis of mode of action, and interactions with other molecules.

Introduction: Wound healing is characterised by haemostatic, inflammatory, proliferative and remodelling phases. In the presence of comorbidities such as diabetes, healing can stall and chronic wounds may result. Infection is detrimental to these wounds and associated with poor outcomes. Wounds are contaminated with microbes and debris, and factors such as host resistance, bacterial virulence, species synergy and bioburden determine whether a wound will deteriorate to critically colonised/infected states. Biofilms are sessile microbial communities, exhibiting high-level antibiotic tolerance and resistance to host defences. Biofilm in critically colonised wounds can contribute to delayed healing. Little is known about clinical presentation and diagnosis of wound biofilms. Objective: To identify from the literature clinical signs, symptoms and biomarkers that may indicate biofilm presence in chronic wounds. Methods: This review will be guided by the Preferred Reporting Items for Systematic Reviews extension for Scoping Reviews (PRISMA-ScR), and the Joanna Briggs Institute Manual for Evidence Synthesis. Studies of any design in any language recruiting adult patients with  venous, diabetic, pressure or mixed arterial-venous ulcers and reporting data on clinical signs/symptoms of biofilm are eligible. Searches of Medline, Embase, CINAHL, Cochrane Central and BASE will be conducted from inception to present. Reference scanning and contact with content experts will be employed. Title/abstract screening and full text selection will be executed by two reviewers independently. Discrepancies will be resolved by discussion between reviewers or through third party intervention. Data will be extracted by a single reviewer and verified by a second. Clinical signs and symptoms data will be presented in terms of study design, setting and participant demographic data. Discussion: Understanding biofilm impact on chronic wounds is inconsistent and based largely on in vitro research. This work will consolidate clinical signs, symptoms and biomarkers of biofilm in chronic wounds reported in the literature.

Recurrent aphthous stomatitis is a common disorder of the oral cavity, affecting mainly young people. It is characterized by small ulcers which can be very painful and generally heal spontaneously within 7–14 days. There is currently no therapy that can provide rapid healing. This study evaluated the efficacy and rapidity of response of a lozenge containing Lactobacillus brevis CD2. 30 patients were randomized to take 4 lozenges a day of active product or placebo for 7 days. Signs and symptoms as well as laboratory parameters in the saliva were assessed at the start of the study and after 7 days of treatment. The study demonstrated the efficacy and the rapidity of response of the Lactobacillus brevis CD2 lozenges in resolving the clinical signs and symptoms of aphthous stomatitis, with a significantly rapid improvement of pain. This is the first study confirming the efficacy of a probiotic product in this pathology.

Pulp diseases commonly happens because of the actions of bacteriological factors and show their characteristic signs and symptoms over the time. With pulp necrosis, a degenerative process starts and when there is no early treatment, it is possible to occur periapical lesions as a result of aggression to the pulp. In cases of periapical secondary lesions, clinical signs and symptoms persist and are related to secondary infection due to persistent bacterial contamination, also to operative factors, inadequate obturation or poor coronary restoration. This study aimed to report a case of endodontic retreatment and clinical and radiographic follow-up for 8 years, of chronic periapical abscess case, in which after retreatment, clinical signs and symptoms are no longer observed and bone neoformation is noticed.

Background. The purpose of this study was to investigate the clinical efficacy and safety of Benjakul (BJK) extract for treating primary osteoarthritis (OA) of the knee compared with diclofenac. Methods. A phase 2, double blind, randomized, and controlled study was conducted. The BJK group received 300 mg of BJK extract per day, while another group received 75 mg of diclofenac per day. All patients were followed up at 14 and 28 days. The changing of visual analogue scale (VAS) for pain, 100-meter walking times, the modified Thai WOMAC index scores, and the global assessment were evaluated for efficacy. For safety issue, clinical signs and symptoms, complete physical examination, and renal and liver function were evaluated. Results. 39 and 38 patients for BJK extract group and diclofenac group were evaluated. For efficacy, all patients from both groups reported a decrease in the VAS pain score and 100-meter walking times but only the diclofenac group showed significant reduction of both measurements when compared with day 0. The modified Thai WOMAC scores of both groups were significantly reduced from baseline. However, all efficacy outcomes were not significantly different for both groups. For safety outcomes, the patients from both groups had no severe adverse events reported and only BJK had no toxicity in renal and liver functions. Conclusions. The BJK remedy extract showed equal clinical efficacy in relieving symptoms of OA knee when compared with diclofenac.

Abstract Infections occurring during neutropenia in cancer patients (pts) frequently involve Gram-positive pathogens and are complicated by antibiotic resistance. Outcomes for infections due to either methicillin-resistant or -susceptible Staphylococcus aureus (MRSA, MSSA) treated with vancomycin are considered suboptimal by many clinicians (Sakoulas G. J Clin Microbiol2004;42:2398–402). New effective agents are needed for treatment. Data were collected retrospectively as part of an ongoing registry (Cubicin Outcomes Registry and Experience; CORE, 2005 and 2006 program years). Data were collected on demographic and microbiologic characteristics; prior, concomitant and follow-up antibiotics; DAP regimen; and clinical data. Outcomes were assessed at the end of DAP therapy by the investigator who, in most cases, was the infectious disease physician involved in the treatment of the patient. The definitions for clinical outcome were: Cure - clinical signs and symptoms resolved (and/or) no additional antibiotic therapy necessary (or) negative culture reported at the end of therapy; Improved - partial resolution of clinical signs and symptoms (and/or) additional antibiotic therapy warranted at the end of therapy; Failure - inadequate response to therapy: worsening or new/recurrent signs and symptoms (or) need for a change in antibiotic therapy (or) positive culture reported at the end of therapy. Pts reported with neutropenia during DAP, a history of cancer, and evaluable for outcome (cure, improved, failure) were analyzed. Eighty-four pts had a history of cancer and had neutropenia during DAP treatment, of these, 72 (86%) were evaluable for DAP outcome. Sixty-five of 72 (90%) pts had either cure (n=40, 56%) or improved (n=25, 35%) as an outcome. Success rates (cure plus improved) stratified by the lowest WBC during DAP were; 29/34 (85%) for < 100 cells/m3, 26/28 (93%) for 100–499 cells/m3, and 10/10 (100%) for 500–1000 cells/m3, P=0.32. The median (range) time to clinical response in those successfully treated (data reported in 47 pts) was 4 days (1–21). Fifty-nine of 72 (82%) had a hematological malignancy. Fifty-eight percent were male, 22% were ≥66 yrs old, 7% had an initial CrCl <30 mL/min, 18% received DAP in an ICU. Eighty-eight percent of pts received antibiotics before DAP, most frequently with vancomycin (83%), cefepime (17%), and linezolid (16%). The most frequent reason for switching to DAP was prior clinical failure / resistance (54%). The major infections being treated with DAP were bacteremia (76%), UTI / pyelonephritis (10%), and uncomplicated skin and skin structure (6%). Seventy-four percent of pts with a WBC < 100 cells/m3 had a bacteremia. The most common Gram-positive pathogens reported were vancomycin-resistant enterococci (52%), coagulase-negative staphylococci (21%), and S. aureus (14%; 7/11, 64% were MRSA). The median (range) initial DAP dose was 6.0 mg/kg (3–7). The median (range) DAP duration of therapy was 13 days (1–86). Nineteen percent of the pts received DAP as an outpatient at some time during their therapy. There were 37 adverse events (AE) reported in 20 (28%) pts; however, only three AEs in 3 pts (4%) were assessed as possibly related to DAP. The data from the registry provide useful information about the clinical characteristics of neutropenic cancer patients treated with DAP for primarily bacteremia. Most of the pts were bacteremic and there was no difference in outcome regardless of the degree of neutropenia. These data require confirmation via prospective clinical trials.
