• Owing to their cutaneous, immunologic, and renal immaturity, newborns (especially premature neonates) are at increased risk of infection. • As a group of potentially life-threatening but often treatable diseases, infections must always be considered in a newborn with skin lesions. • Prompt diagnosis and initiation of therapy are crucial to prevent devastating long-term sequelae, particularly in instances of disseminated disease. • Staphylococcus aureus, Streptococcus species, Candida albicans, and herpes simplex virus are the most common causes of skin infections in the neonate.

Background Ibrutinib is an oral inhibitor of Bruton’s tyrosine kinase (BTK) that is FDA-approved for several lymphoproliferative disorders and chronic GVHD. Objective To characterize cutaneous eruptions arising from ibrutinib and highlight overlap with epidermal growth factor receptor inhibitor (EGFRi)-induced dermatologic adverse events (dAEs). Methods Single-center retrospective cohort of patients referred to the Skin Toxicities Program for management of cutaneous eruptions while taking ibrutinib. Results Among 19 patients, cutaneous eruptions manifested as facial-predominant papulopustular eruptions, petechiae or ecchymoses, photosensitivity, panniculitis, xerosis, and clinical staphylococcal overgrowth. The majority of patients were able to continue ibrutinib therapy with focused management of their cutaneous toxicities. Limitations This study represents cases at a single tertiary care center and is limited to patients referred for toxicity. Conclusions With the exception of petechiae, the cutaneous toxicities of ibrutinib overlap with those associated with selective EGFR inhibitors. We observed that these reactions can be successfully managed using approaches for EGFR inhibitor-induced cutaneous adverse events.

Recognizing sport-related concussion (SRC) is challenging and relies heavily on subjective symptom reports. An objective, biological marker could improve recognition and understanding of SRC. There is emerging evidence that salivary micro-ribonucleic acids (miRNAs) may serve as biomarkers of concussion; however, it remains unclear whether concussion-related miRNAs are impacted by exercise. We sought to determine whether 40 miRNAs previously implicated in concussion pathophysiology were affected by participation in a variety of contact and non-contact sports. Our goal was to refine a miRNA-based tool capable of identifying athletes with SRC without the confounding effects of exercise.This case-control study harmonized data from concussed and non-concussed athletes recruited across 10 sites. Levels of salivary miRNAs within 455 samples from 314 individuals were measured with RNA sequencing. Within-subjects testing was used to identify and exclude miRNAs that changed with either: (a) a single episode of exercise (166 samples from 83 individuals) or (b) season-long participation in contact sports (212 samples from 106 individuals). The miRNAs that were not impacted by exercise were interrogated for SRC diagnostic utility using logistic regression (172 samples from 75 concussed and 97 non-concussed individuals).Two miRNAs (miR-532-5p, miR-182-5p) decreased (adjusted p0.05) after a single episode of exercise, and 1 miRNA (miR-4510) increased only after contact sports participation. Twenty-three miRNAs changed at the end of a contact sports season. Two of these miRNAs (miR-26b-3p, miR-29c-3p) were associated (R0.50; adjusted p0.05) with the number of head impacts sustained in a single football practice. Among the 15 miRNAs not confounded by exercise or season-long contact sports participation, 11 demonstrated a significant difference (adjusted p0.05) between concussed and non-concussed participants, and 6 displayed moderate ability (AUC0.70) to identify concussion. A single ratio (miR-27a-5p/miR-30a-3p) displayed the highest accuracy (AUC = 0.810, sensitivity = 82.4%, specificity = 73.3%) for differentiating concussed and non-concussed participants. Accuracy did not differ between participants with SRC and non-SRC (z = 0.5, p = 0.60).Salivary miRNA levels may accurately identify SRC when not confounded by exercise. Refinement of this approach in a large cohort of athletes could eventually lead to a non-invasive, sideline adjunct for SRC assessment.

A fetus with features of hydrops was given intra-uterine transfusion at 27 weeks and 31 weeks of gestation. Mother had been alloimmunized with anti-D and anti-C antibodies. At birth, laboratory investigations revealed bone marrow suppression along with features of hemolytic anemia. The neonate was started on a combination of phototherapy and intravenous immunoglobulin. During the course, the neonate was transfused with one unit of packed red cells (top-up transfusion). Neonatal hyperbilirubinemia responded to phototherapy and the bone marrow activity spontaneously resumed after 3 weeks of life. In neonates with anemia at birth who have history of multiple intra-uterine transfusions, early-onset hypoproliferative anemia should be considered.

Transient loss of consciousness (TLOC) is a frequent cause of referral to an emergency room. In view of the impact on treatment and the patients’ daily life activities (e. g. profession, driving license), an accurate and timely diagnosis is of uttermost importance. This article provides key features and suggests a practical step-by-step approach of how to differentiate syncope, epileptic and psychogenic non-epileptic seizures as the commonest causes of nontraumatic TLOC.

Abstract: Lipoprotein(a)(Lp[a]) is a low-density lipoprotein-cholesterol (LDL-C)-like particle with potent pro-atherothrombotic properties. The association of Lp(a) with several circulating factors, including vitamins, remains unresolved. We performed an observational analysis using the National Health and Nutrition Examination Survey III cohort, a cohort used to monitor the nutrition status of US-citizens. We used multivariable linear regression to test associations of Lp(a) and LDL-C with levels of serum vitamins and minerals and whole-blood lead. Analyses controlled for factors known to associate with Lp(a) (age, sex, race/ethnicity, statin use, hemoglobin A1c, body mass index, hypertension, diabetes, glomerular filtration rate, alcohol intake, and saturated fat intake). LDL-C was corrected for Lp(a) mass. Multiple sensitivity tests were performed, including considering factors as categorical variables (deficient, normal, elevated). Among 7,662 subjects, Lp(a) correlated (β-coefficient) positively (change per 1 conventional unit increase) with carotenoids (lycopene (0.17(0.06,0.28), p=0.005), lutein (0.19(0.07,0.30), p=0.002), β-cryptoxanthin (0.21(0.05,0.37), p=0.01), β-carotene (0.05(0.02,0.09), p=0.003), and α-carotene (0.15(0.01,0.30), p=0.04)) and lead (0.54(0.03,1.05), p=0.04) levels when tested as continuous variables. LDL-C had similar associations. Lp(a) did not associate with vitamins A, B12, C, or E retinyl esters, folate, RBC-folate, selenium, ferritin, transferrin saturation, or calcium. With factors as categorical variables, Lp(a) but not LDL-C negatively associated with elevated vitamin B12 (−5.41(−9.50, −1.53), p=0.01) and folate (−2.86(−5.09, −0.63), p=0.01). In conclusion, Lp(a) associated similarly to LDL-C when vitamins, minerals, and lead were tested as continuous variables, while only Lp(a) correlated with vitamin B12 and folate when tested as categorical variables. These observations are hypotheses generating and require further studies to determine causality.

Introduction Streptococcus bovis/equinus complex (SBEC) is a major cause of infective endocarditis (IE), although its incidence varies greatly depending on the geographical area. The characteristics of IE caused by Streptococcus gallolyticus susp. gallolyticus are well known; there are hardly any descriptions of IE caused by other species or biotypes. Methods Retrospective cohort study, from 1990 to 2019, of all SBEC IE in adults in three Spanish hospitals, Lugo (LH), Barcelona (BH) and Ferrol (FH) where the population is mainly rural, urban and mixed, respectively. The incidence of IE was analyzed in 3 areas. Clinical characteristics of IE (277 cases, 258 biotyped) were compared according to SBEC species and biotypes. Results There are significant differences between the incidence of SBEC IE in HL (27.9/106) vs. HF and HB (8.8 and 7,1, respectively, p Conclusions IE due to SBEC has geographical variations in incidence and different clinical characteristics among biotypes. The association with CRC was high.

Cystic hydatid disease or cystic echinococcosis (CE) is a globally endemic zoonosis caused by the larval cyst stage of the tapeworm Echinococcus granulosus. Concomitant presence of CE and hepatocellular carcinoma (HCC) is a rare clinical scenario. A 70-year-old male patient presented with acute abdominal pain to the surgical outpatient department. On evaluation, a cystic lesion with solid components and free fluid in the abdomen was observed, which led to multiple differentials in the working diagnosis. A CT showed the mass to have a delayed enhancement. Surgical exploration revealed a partially ruptured hydatid cyst with daughter cysts in the abdominal cavity and a solid-component mass lesion. We proceeded with a right partial hepatectomy. Pathological evaluation revealed a pale mass lesion with a large collapsed cyst. HCC with unusual dense fibrillar fibrosis and cystic interface with normal parenchyma was observed. This case connects the multimodal assessment of radiology, surgery and pathology.

This is a case of a young woman who developed neurological and psychiatric symptoms 3 days after resection of an immature teratoma. She was diagnosed with anti-NMDA receptor encephalitis via positive serum antibody titres, which was later confirmed with cerebrospinal fluid antibody titres. Given her cancer diagnosis, she underwent treatment with bleomycin, etoposide and cisplatin chemotherapy in addition to 5 days of high-dose steroids (1 g of intravenous methylprednisolone) for the encephalitis. This treatment regimen led to significant clinical improvement 3 weeks after completion of one cycle of chemotherapy.

Current literature suggests an increased risk of venous thromboembolism (VTE) in people living with HIV (PLWH) with poorly controlled viraemia and immunodeficiency. VTE treatment guidelines do not specifically address anticoagulation management in PLWH. We report a case of a 33-year-old woman diagnosed with an unprovoked pulmonary embolism (PE) and deemed protein S deficient. Three years later, she was diagnosed with AIDS. Antiretroviral therapy (ART) was promptly initiated with viral suppression and immune reconstitution within 12 months. Eight years after her initial PE, the patient self-discontinued warfarin. Multiple repeat protein S values were normal. ART without anticoagulation has continued for 3 years with no thrombotic events. This case describes a patient with VTE presumably secondary to undiagnosed HIV with possible consequent acquired protein S deficiency. Additional research is needed to understand the characteristics of PLWH with VTE who may warrant long-term anticoagulation as opposed to shorter courses.

Disseminated histoplasmosis is a life-threatening condition in immunocompromised patients. The majority of healthy persons have benign disease not requiring treatment. However, in persons living with HIV, mortality is high and accurate diagnosis is paramount. We present a case of a 48-year-old HIV-positive woman who presented with haematuria and flank pain. She had a history of recurrent urinary tract infection and nephrolithiasis with obstructive hydronephrosis. During cystoscopy, a bladder lesion was found. Pathological evaluation demonstrated abundant intracellular organisms with apparent budding. Subsequent urine histoplasma antigen was negative. Given the high index of suspicion for histoplasmosis based on the surgical pathology findings and epidemiological history, the patient was started immediately on antifungal therapy. One week later, PCR results of the bladder lesion confirmed the presence of Histoplasma capsulatum. This case highlights a rare presentation of genitourinary histoplasmosis and the utility of surgical pathology evaluation and PCR for diagnosis.

We present a case of a 51-year-old immunosuppressed man with underlying chronic lymphoproliferative leukaemia (CLL), who presented to us in emergency with breathlessness, hydrophobia, anxiety and restlessness. He had a history of category 3 dog bite 2 months ago and had received a full course of rabies immunoglobulin and antirabies vaccine (ARV) as per the national schedule. As there were frank clinical reports of rabies, the patient was managed according to Milwaukee regimen. The patients died within a week of the appearance of symptoms. The brain autopsy revealed Negri bodies conforming the mortality due to rabies.Immunosuppressed patients, like our patient who had CLL have low antibody formation after rabies prophylaxis. Antibody titres in immunosuppressed patients need to be measured after the 2–4 weeks of the last injection of ARV to decide whether a booster of ARV needs to be administered or not.

Modulation of proteasome function by pharmacological interventions and molecular biology tools is an active area of research in cancer biology and neurodegenerative diseases. Curcumin (diferuloylmethane) is a naturally occurring polyphenol that affects multiple signaling pathways and known to modulate PKC activities. The therapeutic significance of curcumin is often considered to reside in its anti-inflammatory, antioxidant, anti-angiogenic, or anti-apoptotic properties. However, recent research suggests that the therapeutic efficacy of curcumin may be due to its activity as a potent inhibitor of the proteasome. In this study, we show that both curcumin and its synthetic polyphenolic derivative (didemethylcurcumin), CUIII modulated proteasome activity in a biphasic manner. Curcumin and CUIII increased proteasome activity at nanomolar concentrations but inhibited proteasome activity at micromolar concentrations. Curcumin was more effective than CUIII in relative proteasome activity increase at nanomolar concentrations. Also, curcumin was more effective than CUIII in relative proteasome activity inhibition at micromolar concentration. The docking study was conducted on the 20S proteasome catalytic subunit. Estimated Kd values for curcumin and didemethylcurcumin are 0.0054μM and 1.3167μM, respectively. These values correlate well with the results of the effectiveness of modulation by curcumin compare to CUIII. The small size of CUIII makes its dock to the narrow cavity of the active site, but the binding interaction is not strong compare to curcumin. This study suggests that curcumin and its didemethyl derivative can be used to modulate proteasome activity. This communication implicates the reason why curcumin and its didemethyl derivative can be used to two different disease mechanisms, neurodegeneration, and cancer.

Background Latent tuberculosis infection (LTBI) diagnosis in a country with a low tuberculosis burden is complicated. Since the prevalence of LTBI in second generation immigrants has not been well recognized, we conducted a cross-sectional study which aimed to explore the differences in LTBI prevalence between offspring of immigrants from high tuberculosis (TB) burden countries and those whose parents were born in countries with a low TB burden. Methods Between May 2014 and April 2018 young native Israelis who were required to perform pre-occupational tuberculin skin tests (TST) (medical and paramedical personnel or teaching assistants of immigrants from high TB burden countries) and who had a TST result of 10 mm and above were tested for QuantiFERON-TB In Tube (QFT-GIT). Statistical comparisons were made between second generation immigrants and those with both parents from a low TB burden country. Results Of 102 patients, 71 were born to parents both of whom were from low-risk countries, 14 to one parent from a high-risk country and 17 to parents both of whom were from a high-risk country. The odds ratio for LTBI was 4.5 (95% CI, 1.2–17.2; p = 0.03) if both parents were born in a high-risk country compared to both parents being from a low-risk country and 4.01 (95% CI, 1.12–14.3; p = 0.03) higher compared to persons for whom at least one parent was born in a low-risk country. Conclusion The risk for latent TB is significantly higher in second generation immigrants if both parents were born in a high-risk country. IGRA should be considered before treatment to patients with a positive TST if at least one parent was born in a low-risk country in order to confirm LTBI.

PURPOSE Immunohistochemistry (IHC) is a newer technique for assessing the estrogen receptor (ER) status of breast cancers, with the potential to overcome many of the shortcomings associated with the traditional ligand-binding assay (LBA). The purpose of this study was to evaluate the ability of ER status determination by IHC, compared with LBA, to predict clinical outcome—especially response to adjuvant endocrine therapy—in a large number of patients with long-term clinical follow-up. PATIENTS AND METHODS ER status was evaluated in 1,982 primary breast cancers by IHC on formalin-fixed paraffin-embedded tissue sections, using antibody 6F11 and standard methodology. Slides were scored on a scale representing the estimated proportion and intensity of positive-staining tumor cells (range, 0 to 8). Results were compared with ER values obtained by the LBA in the same tumors and to clinical outcome. RESULTS An IHC score of greater than 2 (corresponding to as few as 1% to 10% weakly positive cells) was used to define ER positivity on the basis of a univariate cut-point analysis of all possible scores and disease-free survival (DFS) in patients receiving any adjuvant endocrine therapy. Using this definition, 71% of all tumors were determined to be ER-positive by IHC, and the level of agreement with the LBA was 86%. In multivariate analyses of patients receiving adjuvant endocrine therapy alone, ER status determined by IHC was better than that determined by the LBA at predicting improved DFS (hazard ratios/ P = 0.474/.0008 and 0.707/.3214, respectively) and equivalent at predicting overall survival (0.379/.0001 and 0.381/.0003, respectively). CONCLUSION IHC is superior to the LBA for assessing ER status in primary breast cancer because it is easier, safer, and less expensive, and has an equivalent or better ability to predict response to adjuvant endocrine therapy.

Periodontitis is an oral chronic inflammatory disease. Inhibiting tissue destruction and promoting tissue regeneration are important means for the treatment of periodontitis. Metformin not only has hypoglycemic effect but also has anti-inflammatory effect. Metformin has been shown to inhibit oxidative stress and activate autophagy through AMPK/mTOR pathway. High mobility group box 1 (HMGB1) has been implicated in the pathogenesis of many inflammatory diseases including periodontitis, it can participate in the induction of oxidative stress. HMGB1 is an autophagy regulator under oxidative stress, which can activate mTOR pathway. However, it is not clear whether metformin is related to HMGB1 and its mechanism in the process of periodontitis. Cell viability and expression of inflammatory cytokines were clarified by Cell Counting Kit-8, real-time PCR and enzyme-linked immunosorbent assay. Western blot and immunofluorescence were conducted to determine HMGB1 intracellular localization and expression of autophagy-associated proteins in vitro. Experimental periodontitis mice model was induced by administering a ligature. Immunohistochemistry was performed to detect the expression and localization of HMGB1 in vivo. The results of CCK-8, real-time PCR, enzyme-linked immunosorbent assay, Western blot and immunofluorescence showed lipopolysaccharide (LPS) treatment inhibited cell viability, and increased HMGB1 expression at a dose-independent manner. Metformin can reduce the effect of LPS. It also improves autophagy pathway inhibited by LPS and down-regulates mTOR expression. In addition, metformin attenuated alveolar bone resorption induced by ligation. This study provides new evidence for that metformin is a potential drug for the treatment of periodontitis and HMGB1 may be a potential target for periodontal intervention.

Introduction: It is reported that migraine may be a risk factor for brain cancers. Since one of the best ways to assess this possible relationship is to study the molecular mechanism, here the common central dysregulated proteins between these diseases are investigated via network analysis. Methods: The dysregulated proteins of migraine and gliosarcoma are extracted from the STRING database and interacted via Cytoscape software, version 3.7.2. to form two separate networks. Central nodes of the networks are compared to find the common central district proteins. First neighbors of the common central proteins are studied. Results: The number of 11 hub bottlenecks was identified for each of the migraine and gliosarcoma cancer networks. Albumin (ALB) and interleukin 6 (IL6) were introduced as common differentially expressed central proteins. Kininogen 1 (KNG1), vascular endothelial growth factor A (VEGFA), and neurofibromatosis type I (NF1) the first neighbors of ALB-IL6 were connected to the central nodes of networks of the two studied diseases. Conclusion: ALB and IL6 can be considered molecular links between migraine and brain cancers.

A 23-year-old man with a history of migraine and focal seizures, developed painless visual loss in the left eye associated with optic disk edema. There was no recent history of cat exposure except for a cat that lives outside. Initial laboratory studies were negative. magnetic resonance imaging brain and orbits without and with fat suppression and intravenous contrast was normal. The patient admitted to routinely skinning, processing and consuming deer while not wearing gloves, and he also frequently had cuts on his hands while doing so. The serum Toxoplasma gondii IgG antibody returned at400 (0-7.1 IU/mL) with the IgM at 10.4 (0-7.9 AU/mL).

Anaemia is a common complication of chronic kidney disease. The most important contributory factor is an abnormally low circulating concentration of erythropoietin, which is produced by the kidney peritubular cells. Anaemia of kidney disease is likely to develop once the glomerular filtration rate (GFR) is

Background: Stress induces secretion of cathecolamines and glucocorticoids, which may produce liver injury. Followed by the production of inflammatory mediators, it causes apoptosis. Centella asiatica (CeA) has anti-inflammatory and hepatoprotective effects. The present study aims to determine the role of CeA in the attenuation of liver pro-inflammatory mediator expression in rats with electrical foot shock stress model. Materials and Methods: Twenty-four Sprague-Dawley rats were randomized into four groups consisted of six rats each: (1) Control group, (2) CeA-treated group, (3) Stress group, and (4) CeA + stress group. Reverse transcriptase PCR of inflammatory and apoptosis markers as well as Real-Time PCR of β2-adrenergic receptor were performed from liver tissues. Results: Electrical foot shock stress induced up-regulation of NFκB and TNF-α mRNA expressions as pro-inflammatory mediators, compared to control group. This alteration was followed by up-regulation of BAX and β2-adrenergic receptor, as well as the down-regulation of BCl2 compared to control. CeA treatment prevented enhancement of NFκB, TNF-α, TLR-4 and β-adrenergic receptor mRNA expressions, which was followed by down-regulation of BAX and up-regulation of BCl-2, compared to stress group. Conclusion: CeA prevents secretion of pro-inflammatory chemokines and cytokines as well as apoptotic markers in liver cells through the activation of β2-adrenergic receptor.

Mosquitoes serve as the major vector transmitting malaria, dengue, yellow fever and several other diseases of human concern. Rising in mosquito-borne diseases and consequent fatalities throughout the world has made the management of mosquitoes of paramount importance. With the use of various insecticidal agents and their indiscriminate application in the fields for vector control; other issues such as multiple insecticide resistance, lethality to non-specific targets and adverse effects on human and environmental health have emerged making the situation more critical. Hence, the focus of researchers has diverted to the use of Insect Growth Regulators (IGRs) that affect the growth and development of the insects without inducing any appreciable toxic effects. The paper comprehensively reviews various IGRs and their potential use against insect pests and mosquito vectors. A special emphasis has been laid on the utilization of diflubenzuron, its larvicidal potency and growth regulatory effects against mosquitoes. The paper also delivers a detailed discussion on various approaches governing with the application of diflubenzuron, a chitin synthesis inhibitor, for its potent effects over a wide range of other insect species, low toxicity to humans, safety to other non-target animals, negligible deleterious environmental impact along with the possible development of resistance in the mosquitoes, thereby providing insights and the direction for the future in terms of the innovative and technological perspective. Keeping in view the role of multifarious mechanisms in the development of resistance; use of various synergistic compounds, such as hydrolase inhibitors - profenofos and S,S,S-tributyl phosphorotrithioate; glutathione S-transferase inhibitor – diethylmaleate; and oxidase inhibitor - piperonyl butoxide (PBO); has been recommended in combination with IGRs to enhance their efficacy, and reduce or reverse the resistance in target mosquitoes. Another compound, verapamil, has been found extremely efficient in imparting synergistic effect to diflubenzuron by inhibiting P-glycoproteins, a transporter of the insecticides causing their efflux from the cell. Recommendations have been made for safe and effective mosquito control measures, adequate policies and increased awareness about the mosquito-borne diseases among the masses. In addition, regular surveillance of mosquitoes is endorsed for the formulation of an efficient mosquito management strategy.

Background: Methadone maintenance treatment (MMT) is an effective treatment for opioid use disorder. However, subtherapeutic dosing may lead to continued opioid use by failing to suppress opioid withdrawal and craving. Preclinical and pilot experimental research suggests that cannabinoids may reduce opioid withdrawal and craving. We sought to test whether the association between low methadone dose and illicit opioid use differs according to concurrent cannabis use patterns. Methods: Data for this study were derived from two community-recruited cohorts of people (≥18 years old) who use illicit drugs in Vancouver, Canada. We used generalized estimating equations to estimate the adjusted association between lower daily MMT dose (

Background A subset of patients with estrogen receptor (ER)-positive, HER2-negative, and node-negative breast cancer experience recurrences. Predicting patients who will have recurrences within 5 years of surgery is essential so that patients can be selected to receive adjuvant chemotherapy. The 95-gene classifier (95-GC) has been validated as a method to differentiate patients into high and low-risk groups for early recurrence. Methods In this study, we performed 95-GC analysis on 56 formalin-fixed paraffin-embedded (FFPE) tissue samples from patients who underwent surgery for ER-positive, HER2-negative, and node-negative breast cancer and did not receive adjuvant chemotherapy. We associated the obtained high- and low-risk groups with clinicopathological characteristics and recurrence-free survival (RFS).Results We classified 12 out of 56 patients into the high-risk recurrence group. We found significantly higher KI67 scores in patients in the high-risk group. Other clinicopathological characteristics were not associated with the 95-GC risk groups. Patients in the 95-GC low-risk group had a significantly better prognosis than those in the high-risk group (p = 0.0387). The 5-year RFS rate was 97.6% in the low-risk group and 74.1% in the high-risk group, while the 10-year RFS rates were 90.1% and 74.1%, respectively.Conclusions Our study shows that the 95-GC score can accurately predict RFS within 5 years of surgery for ER-positive, HER2-negative, and node-negative breast cancer using FFPE tissue samples. These prediction models could help assign patients to the most effective treatment regimen.

Patients with angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema (ACEIIA) may visit family physicians. The aim of this article was to describe a case of delayed-onset ACEIIA and to present a concise scoping review. Using a case report and a scoping review study design, we report a case of ACEIIA, with clinically confirmed diagnosis. The symptoms resolved after replacing the offending ACEI with another antihypertensive agent. After excluding other causes of perioral swelling and discontinuation of ACEI, the patient was symptom-free within a few days thereafter. Based on this case presentation, we performed a meta-narrative scoping review including up-todate diagnosis and management of ACEIIA, based on published data in English, French, and German from inception to April 1, 2021. Patients with angioedema of unknown origin should be cautiously examined to rule out oral diseases, including allergy to dental materials and drug-induced angioedema. Clinicopathological aspects and current treatment guidelines for ACEI-associated angioedema are also presented.

Gold was considered as universal remedies for diseases like inflammation, infections, etc in 19th century. Later in 20th century Robert Koch discovered Gold complex Potassiumdicyanidoaurate(I) showing activity against Mycobacterium tuberculosis, later the treatment was proved to be ineffective subsequently. Further in 1985 Auranofin (Gold salt) was introduced for the treatment of Rheumatoid Arthritis, which had to be taken orally and believed to be the major discovery till injectable gold came into existence. The function of drugs based on gold is majorly related to Rheumatoid arthritis but engrossment has bent towards the adequacy of Gold compounds for anti cancer activities. The review article summarizes the current research on Gold complexes and their biological activities against cancer as well as in case of RA.

Malaria, Zika virus, West Nile virus, Dengue fever, and Lyme disease are common causes of morbidity and mortality around the world. While arthropod bites may cause local inflammation and discomfort, a greater concern is the potential to develop deadly systemic infection. The use of insect repellents (IR) to prevent systemic infections constitutes a fundamental public health effort. Cost-effectiveness, availability, and high-efficacy against arthropod vectors are key characteristics of an ideal IR. Currently, numerous IRs are available on the market, with DEET (N,N-diethyl-3-methylbenzamide) being the most widely used. DEET has an excellent safety profile and remarkable protection against mosquitoes and various other arthropods. Other EPA-registered IR ingredients (permethrin, picaridin, IR3535, oil of lemon eucalyptus, oil of citronella, catnip oil, and 2-undecanone) are alternative IRs of great interest due to some having efficacies comparable to that of DEET. These alternative IRs possess low toxicity and favorable customer experiences in utilization (e.g., cosmetically pleasant, naturally occurring). This review summarizes currently available EPA-registered IRs: the origins, mechanisms of action, side effect profiles, and available formulations will be discussed. This review will enable the clinician to select the best IR option to meet patients' needs and provide the greatest protection from arthropod bites and sequelae.

Introduction Advances in the development of drugs with novel mechanisms of action have not been sufficient to significantly reduce the percentage of patients presenting drug-resistant epilepsy. This lack of satisfactory clinical results has led to the search for more effective treatment alternatives with new mechanisms of action. Development The aim of this study is to examine epidemiological aspects of the use of cannabis-based products for the treatment of epilepsy, with particular emphasis on the main mechanisms of action, indications for use, clinical efficacy, and safety. We conducted a narrative review of articles gathered from the PubMed, EMBASE, and Google Scholar databases and from the reference sections of relevant publications. Conclusions In recent years there has been growing interest in the use of cannabis-based products for the treatment of a wide range of diseases, including epilepsy. The cannabis plant is currently known to contain more than 100 terpenophenolic compounds, known as cannabinoids. The 2 most abundant are delta-9-tetrahydrocannabinol and cannabidiol. Studies of preclinical models of epilepsy have shown that these cannabinoids have anticonvulsant properties, and 100% purified cannabidiol and cannabidiol-enriched cannabis extracts are now being used to treat epilepsy in humans. Several open-label studies and randomised controlled clinical trials have demonstrated the efficacy and safety of these products.

Klebsiella pneumoniae has been identified as one of the important pathogens involved in the pathogenesis of urinary tract infections (UTIs) in humans. This study sought to determine the prevalence of K. pneumoniae and its ability to produce extended-spectrum-β-lactamases (ESBLs) in patients with UTIs. Besides, the predictive significance of interleukin (IL)-15 in UTIs caused by ESBLs-producing K. pneumoniae (K-ESBLs) was also assessed.: During October 2020 – January 2021, a cross-sectional and case-control study was performed on 587 patients with UTIs. Serum level of IL-15 was assessed using an enzyme-linked immunosorbent assay kit. The prevalence of K. pneumonia was 15.8%. It was also found that 68.8% of the K. pneumonia isolates were K-ESBLs (64patients). IL-15 levels were significantly elevated in serum of UTI patients with K-ESBLs compared to 24 control subjects (29.4 ± 9.2 vs. 22.1 ± 5.1; p-value

Introduction During pregnancy, women are at an increased risk of developing iron-deficiency anemia. Objective The objective of this study was to assess the diagnostic performance of the reticulocyte hemoglobin equivalent (RET-He) in the early detection of iron-deficiency anemia in a group of pregnant women and to establish a reference range for this parameter in a group of control individuals. Method: A total of 60 patients and 130 control subjects were included in the study. Blood samples collected from the subjects were submitted to a complete blood count and a serum ferritin test and the data were analyzed by comparing the groups and ROC curves. Results The reference range found for the RET-He was between 29.75pg and 38.24pg, with a median of 35pg. The receiver operating characteristic (ROC) curve analysis for the ferritin parameter showed an area under the curve of 0.732 for the RET-He, 0.586 for hemoglobin, 0.551 for the mean corpuscular hemoglobin concentration and 0.482 for the mean corpuscular volume. Conclusion Early diagnosis of iron deficiency anemia in pregnancy is essential to prevent damage to both maternal and fetal health. The RET-He presents an excellent potential as an auxiliary tool for the diagnosis of iron deficiency in pregnant women.

Introduction: Cognitive deficit is one of the common comorbidity accompanying epilepsy. The present study evaluated the effect of Celastrus paniculatus seed extract on seizure severity and cognitive deficit following the pentylenetetrazole (PTZ)-induced chemical kindling model. Methods: PTZ kindling model was developed by daily administration of the sub-convulsive dose of PTZ 30 mg/kg for four weeks. After four weeks of induction, the following treatment, namely sodium valproic acid (SVA) 200 mg/kg, C. paniculatus 500 mgkg, pergolide 2 mg/kg, C. paniculatus (250 mgkg)+ Pergolide (1 mg/kg), and C. paniculatus (250 mgkg)+ SVA (100 mg/kg) were administered 30 minutes prior to PTZ (30 mg/kg) injection for a period of next 14 days. Neurobehavioral parameters, including superoxide dismutase (SOD), Catalase (CAT), glutathione (GSH), and dopamine levels were assessed and the Morris water maze test (MWM) and Grip strength test (GPS) were performed. Hematoxylin & Eosin (H&E) staining of hippocampal cornu ammonis (CA1), CA2, CA3, dentate gyrus (DG), and frontal cortex was performed. Results: C. paniculatus (500 mg/kg) alone and in combination ( C. paniculatus (250 mgkg)+ pergolide (1 mg/kg) and C. paniculatus (250 mgkg)+ SVA (100 mg/kg)) significantly (p

Neurological paraneoplastic syndrome is a relatively rare condition in patients with malignant tumors. Recently, it has been reported that anti-Aquaporin 4 (AQP4) antibody is highly specific for neuromyelitis optica. The patient was a 76-year-old man. He underwent right upper lobectomy for squamous cell carcinoma of the lung. Although the immediate postoperative course was uneventful, neurological symptoms became apparent from postoperative day (POD) 4. Magnetic resonance imaging showed longitudinally extended edematous lesions in the spinal cord, and a cerebrospinal fluid examination was positive for anti-AQP4 antibody, leading to the diagnosis of paraneoplastic neuromyelitis optica. Despite multiple rounds of steroid pulse therapy and plasma exchange, the neurological symptoms worsened and the patient died on POD 46. The development of neuromyelitis optica in the early postoperative period could be related to the influence of surgical stress or epidural anesthesia.

Helicobacter pylori (H. pylori) is a spiral microorganism considered as a gram-negative, this organism colonize the microenvironment of gastric for more than 50% of world population. The present study involved 78 patients, 39 of them had a clinical diagnosis of gastric ulcer and the remaining 39 had a clinical diagnosis of gastric cancer. Biopsies were taken from December 2018” until the end of July 2019 and the patients were between 25 and 60 years old. The initial diagnosis of H. pylori was performed by the rapid urease test (RUT). The samples also have been tested for IL-17 gene expression by immunihistochemical techniques. All the samples have been investigated for UreA gene, and the results showed the H.pylori positive in 32 (82%) samples and it was negative in 7 (18%) samples in gastric cancer, whereas the gastric ulcer group showed 29 (75%) negative samples and 10 (25%) positive for H.pylori. Furthermore, the sequencing result of gastric cancer group showed 95% compatibility, while gastric ulcer patients showed 98% compatibility with NCBI. The phylogenetic analysis exhibited the genetic dimension among the samples and the world was 96% and 99% compatibility values.

The advent of immunotherapy has revolutionised the treatment of metastatic lung cancer and it has recently been established as the standard of care in the radical treatment of lung cancer. However, immune-related adverse events (IrAEs) frequently occur in patients treated with immunotherapy, and rare IrAEs continue to be identified. We report a case of immunotherapy-induced coeliac disease due to adjuvant durvalumab post-chemoradiotherapy in a patient receiving curative treatment for lung cancer. The patient had raised anti-tissue transglutaminase IgA and histological findings consistent with coeliac disease. This is the first published case report of probable immunotherapy-induced coeliac disease both with the immunotherapy drug durvalumab and in the curative lung cancer setting.

Essential thrombocythaemia (ET) is a myeloproliferative neoplasm where there is a clonal proliferation of thrombocytes. Whilst most often diagnosed incidentally, it can uncommonly present with arterial thrombosis. This is a case presentation of a 36-year-old male who was diagnosed with ET following myocardial infarction caused by multiple thrombotic emboli. The patient was initially misdiagnosed with viral myopericarditis based on an atypical history of chest pain with a viral prodrome. Reattendance a month later with further chest pain, dynamically raised troponin and ECG changes raised suspicions of ACS. Analysis of blood markers from both admissions showed consistently elevated platelet counts. A CMR scan revealed focal ischaemic scars in multiple cardiac segments consistent with an acute coronary event or coronary embolisation. A subsequent coronary angiography demonstrated minimal coronary artery disease. JAK2 gene V617F mutation was detected, confirming ET. The patient was commenced on pegylated interferon-alpha and dual antiplatelet therapy, and discharged with follow-up.

Eight-and-a-half syndrome is a rare entity characterised by conjugate horizontal gaze palsy, ipsilateral internuclear ophthalmoplegia and ipsilateral lower motor neuron type facial palsy. It is due to a lesion affecting median longitudinal fasciculus, paramedian pontine reticular formation and facial nerve fascicle on the same side at the level of pons. The diagnosis is easily missed as it needs detailed ocular movement examination. It is mainly caused due to infarction or demyelinating conditions. We are reporting an interesting case of a 54-year-old man with right-side eight-and-a-half syndrome due to acute ischaemic stroke and ST-elevation myocardial infarction of the inferior wall.

Primary pneumomediastinum is the presence of air in the interstitium of the mediastinum. The exact aetiology is unclear; nevertheless, it has been reported more frequently in patients with asthma and in individuals who use recreational drugs. It is commonly preceded by a sharp rise in intrathoracic pressure as in a Valsalva-like manoeuvre. We describe a rare case of severe pneumomediastinum with a small pneumothorax related to cannabis smoking and aggravated by vigorous sexual intercourse. The patient was successfully treated conservatively due to clinical and radiological stability and the absence of secondary cause.

Background Allergic bronchopulmonary aspergillosis (ABPA) is an allergic reaction to colonisation of the lungs with the fungus Aspergillus fumigatus and affects around 10% of people with cystic fibrosis. ABPA is associated with an accelerated decline in lung function. High doses of corticosteroids are the main treatment for ABPA; although the long-term benefits are not clear, their many side effects are well-documented. A group of compounds, the azoles, have activity against Aspergillus fumigatus and have been proposed as an alternative treatment for ABPA. Of this group, itraconazole is the most active. A separate antifungal compound, amphotericin B, has been employed in aerosolised form to treat invasive infection with Aspergillus fumigatus, and may have potential for the treatment of ABPA. Antifungal therapy for ABPA in cystic fibrosis needs to be evaluated. This is an update of a previously published review. Objectives The review aimed to test the hypotheses that antifungal interventions for the treatment of ABPA in cystic fibrosis: 1. improve clinical status compared to placebo or standard therapy (no placebo); 2. do not have unacceptable adverse effects. If benefit was demonstrated, we aimed to assess the optimal type, duration and dose of antifungal therapy. Search methods We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. In addition, pharmaceutical companies were approached. Date of the most recent search of the Group's Trials Register: 29 September 2016. Selection criteria Published or unpublished randomised controlled trials, where antifungal treatments have been compared to either placebo or no treatment, or where different doses of the same treatment have been used in the treatment of ABPA in people with cystic fibrosis. Data collection and analysis Four trials were identified by the searches; none of which was judged eligible for inclusion in the review. Main results No completed randomised controlled trials were included. Authors' conclusions At present, there are no randomised controlled trials to evaluate the use of antifungal therapies for the treatment of ABPA in people with cystic fibrosis, although trials in people who do not have cystic fibrosis have shown clinical and serological evidence of improvement and a reduction in the use of corticosteroids with no increase in adverse effects. Trials with clear outcome measures are needed to properly evaluate this potentially useful treatment for cystic fibrosis.

Background Gastric cancer is worldwide the fourth more common cancer type by incidence, and the third by mortality. We analyzed three missense variants of TAS2R38 gene: rs713598 (A49P), rs1726866 (V262A), and rs10246939 (I296V). These variants and their combination in haplotypes (proline, alanine and valine/tasters or alanine, valine and isoleucine/nontasters) and diplotypes are responsible for individual differences in bitter perception. The single-nucleotide polymorphisms and the related phenotypes are known to be associated with susceptibility to Gram-negative bacterial infections, such as Helicobacter pylori, and with risk of various cancer types. An association between intermediate tasters (as defined by TAS2R38 diplotypes) and increased risk of gastric cancer was reported in a Korean population. Methods We analyzed 2616 individuals of Latin American origin, representing the whole spectrum of lesions from gastritis to gastric cancer. Results Comparing cancer cases vs. noncancers we observed a decrease in risk associated with heterozygous carriers of rs10246939 (P = 0.006) and rs1726866 (P = 0.003) when compared with homozygotes of the more common allele. Also, the analysis of diplotypes/phenotypes reflected the same association, with super-tasters showing a borderline increased risk of developing gastric cancer compared to medium-tasters [odds ratio (OR) = 1.63; 95% confidence interval (CI), 1.04-2.56; P = 0.033]. Also, nontasters showed an increased risk when compared to medium-tasters although not reaching statistical significance (OR = 1.58; 95% CI, 0.80-2.87; P = 0.203). We also tested the interactions between the TAS2R38 genotypes and H. pylori cagA status in a subset of samples and found no interaction. Conclusion In conclusion, our results suggest only a modest contribution of TAS2R38 gene genetic variability in gastric cancer etiology.

SIGNIFICANCE Reactive oxygen species (ROS) contribute to multiple aspects of peripheral nervous system (PNS) biology ranging from physiological processes (e.g. axonal outgrowth and regeneration), to pathophysiology (e.g. nerve degeneration). Although ROS are derived from multiple sources, NADPH oxidase (Nox) family members are dedicated to ROS generation. Noxs are expressed in the PNS and their overexpression is associated with detrimental effects on nerve function and contribute, at least in part, to peripheral neuropathies. Recent Advances: Of the 7 members, studies mostly focused on Nox1, Nox2, and Nox4, which are expressed in the PNS in a cell-specific manner. We have also recently identified human Nox5 in sural nerve biopsies. When maintained at homeostatic levels, Noxs regulate several aspects of peripheral nerve health, most notably neurite outgrowth and axonal regeneration following nerve lesion. While Nox2 and Nox4 dysregulation is a major source of oxidative stress in PNS disorders, including neuropathic pain and diabetic peripheral neuropathy, recent evidence also implicates Nox1 and Nox5. CRITICAL ISSUES Although there is compelling evidence for a direct role of Noxs on nerve function, little is known about their subcellular localization, intercellular regulation, and interaction. These, together with redox signaling, are considered crucial components of nerve redox status. Additionally, the lack of isoform-specific inhibitors limits conclusions about the physiological role of Noxs in the PNS and their therapeutic potential in peripheral neuropathies. FUTURE DIRECTIONS Future research using isoform-specific genetic and pharmacological approaches are therefore needed to better understand the significance of Nox enzymes in PNS (patho) physiology.

We present a case of a 7-year-old Afro-Caribbean girl presenting with rapidly progressive bilateral sensorineural hearing loss. She was found to have an elevated Angiotensin converting enzyme (ACE) and mediastinal lymphadenopathy containing non-caseating granulomas with multinucleate giant cells, in keeping with sarcoidosis. Cranial imaging demonstrated labyrinthitis. She underwent urgent bilateral cochlear implantation with rehabilitation of hearing sufficient to restart education within 1 month.

Vancomycin is a widely used antibiotic and rarely can cause drug-induced thrombocytopenia. A patient with hospital-acquired meningitis after neurosurgery was treated with systemic and intrathecal vancomycin. On 9th day of antibiotic treatment, the patient’s platelets dropped to 0.68×109/L. Multiple platelet transfusions had minimal influence on platelet count. After cessation of vancomycin therapy, platelets returned to normal values without any additional interventions. Diagnosis of vancomycin-induced thrombocytopenia was confirmed by detection of drug-dependent antiplatelet IgG antibodies.

Introduction: Cannabis use is common in the setting of inflammatory bowel disease (IBD). Patients frequently use cannabis to treat IBD-associated symptoms, and there is evidence that cannabis and its derivatives are helpful for this purpose. However, it is unclear how the symptom profiles of active IBD cannabis users and nonusers compare and how these symptoms may relate to their underlying disease state and/or complications. Materials and Methods: We performed a retrospective cohort study using a consented IBD natural history registry from a single tertiary care referral center between January 1, 2015 and August 31, 2020. We asked patients about current cannabis use and frequency. We also abstracted demographic and clinical characteristic information, including endoscopic severity, and totals and subscores of surveys assessing IBD characteristics, presence of anxiety/depression, and IBD-associated symptoms. We compared clinical and demographic factors of cannabis users and nonusers and developed a logistic regression model to evaluate for independent associations with cannabis use. Results: Three hundred eighty-three IBD patients met the inclusion criteria (206 females, 177 males; 258 Crohn's disease [CD], 118 ulcerative colitis, and 7 indeterminate colitis). Thirty patients (7.8%) were active cannabis users, consuming it for an average of 2.7 times per week. Cannabis users were more likely to report abdominal pain (83.3% vs. 61.7%), gas (66.7% vs. 45.6%), tenesmus (70.0% vs. 47.6%), and arthralgias (53.3% vs. 20.3%) compared to those that did not use cannabis (p

Objective: The objective of this study was to evaluate the safety and efficacy of medications commonly used in autism spectrum disorder (ASD) and compare this to what current research has shown regarding medical cannabis use in this population. Methods: Searches were performed to collect information surrounding currently used medications and their safety and efficacy profiles, biologic plausibility of cannabis use for symptoms of ASD, and studies detailing cannabis' safety and efficacy profile for use in the ASD population. Results were used to compare medications to cannabis as a proposed treatment. Results: The heterogeneity of ASD produces great difficulties in finding appropriate treatment, leading to many medication changes or treatment trials throughout a patient's life. Commonly prescribed medications display varying levels of efficacy, safety, and tolerability between patients and symptoms targeted. Some of the most common side effects cited are also considered the most troubling symptoms associated with ASD; aggression, anxiety, irritability, and a negative effect on cognition, leading many patients to discontinue use as the side effects outweigh benefits. Recent case reports and retrospective studies have displayed the potential efficacy, safety, and tolerability of cannabidiol (CBD)-rich medical cannabis use for treating both core symptoms of ASD and many comorbid symptoms such as irritability and sleep problems. Studies have also identified circulating endocannabinoids as a possible biomarker for ASD, providing another possible method of diagnosis. Conclusions: Currently, there are no approved medications for the core symptoms of ASD and only two medications Food and Drug Administration approved for associated irritability. Prescribed medications for symptoms associated with ASD display varying levels of efficacy, safety, and tolerability among the heterogeneous ASD population. At the time of this study there are no published placebo-controlled trials of medical cannabis for ASD and the observational studies have limitations. CBD-rich medical cannabis seems to be an effective, tolerable, and relatively safe option for many symptoms associated with ASD, however, the long-term safety is unknown at this time.

Chronic cavitary pulmonary aspergillosis (CCPA) is a slow destructive type of chronic pulmonary aspergillosis, characterised by multiple pulmonary cavities that develop and expand over several months or years. Pleural involvement in the form of pneumothorax has been rarely reported in CCPA. We report such an unusual case of an immunocompromised male, with a history of chronic cough and fever, presenting with acute onset of shortness of breath. Chest imaging showed bilateral multiple cavitating nodules, ground glass opacities and dense right middle lobe consolidations and right-sided pneumothorax. Bronchoalveolar lavage (BAL) showed septate hyaline hyphae on KOH (potassium hydroxide) staining and fungal culture grew Aspergillus fumigatus. BAL and serum galactomanan were positive and serum IgG for A. fumigatus was 58 MgA/L (0–40MgA/L) confirming the cause of spontaneous secondary pneumothorax in our patient as CCPA.

A 42 year-old Caribbean woman with, known type 2 diabetes, was admitted with worsening fatigue, arthritis and rashes. She was diagnosed with multisystem systemic lupus erythematosus and was initially treated with systemic steroids. During this admission, she had persistently elevated capillary glucose levels with insulin requirements over 8 U/kg/day that still did not control her blood glucose levels. Due to her profound hyperglycaemia, serum samples of fasting insulin, C-peptide, paired with blood glucose were analysed, which confirmed significant hyperinsulinaemia. Further analysis confirmed the presence of insulin receptor antibodies consistent with type B insulin resistance.She was started on intravenous cyclophosphamide (Euro-Lupus regimen) along with continuous glucose monitoring system. After completing her six cycles of cyclophosphamide, she no longer required insulin treatment. The goal of therapy for our patient with confirmed type B insulin resistance was to manage hyperglycaemia with high doses of insulin until autoantibodies were eliminated with immunosuppressive therapy.

Infection is a serious adverse event limiting left ventricular assist device (LVAD) therapy in advanced heart failure patients, but a reliable means to identify patients at increased risk of infection is still lacking. We hypothesized that preoperative elevated levels of plasma Oncostatin M (OSM), a cytokine marker of leukocyte activation and inflammation, would be predictive of subsequent infection. We measured plasma OSM in 41 LVAD patients one day before LVAD implantation and postoperatively over two months. Preoperative plasma OSM levels were normal in 27 patients (group A, 4.9 ± 3.2 pg/ml) but elevated in 14 patients (group B, 1649.0 ± 458.9 pg/ml) ( p = 0.003). Early postoperative levels rose in both groups and declined rapidly in group A, with group B declining slowly over two months. Significantly more infections developed in group B than group A patients over two months postimplantation ( p = 0.004). No other routine clinical assessment or laboratory testing afforded this differentiation. These findings suggest that preoperative plasma OSM levels may assist in identifying patients at increased risk of infections after LVAD implantation.
