The actual GPI-anchored health proteins CD109 safeguards hematopoietic progenitor tissues via starting erythroid differentiation induced through TGF-β.
Objective Ocular infections due to multi-drug-resistant Pseudomonas aeruginosa (MDRP) have been reported in recent years. This study was undertaken to determine the culture-positivity rate of P. aeruginosa and drug resistance among patients with suspected external ocular infections and to predict systemic risk factors for drug resistance in P. aeruginosa. Methods This retrospective, single-center, cross-sectional study involved 781 consecutive patients who provided samples for aerobic culture to test for a suspected external ocular infection. DRP was defined as a strain resistant to one or two of three antibiotics, levofloxacin, gentamicin, and imipenem; MDRP was defined as that which was resistant to all three. Results Among 108 patients in whom gram-negative bacilli were observed, P. aeruginosa was isolated from nine patients, including three DRP-positive cases; no MDRP was isolated. P. aeruginosa was not isolated from those less then 69 years of age. Among patients in whom gram-negative bacilli were detected, the isolation rate of P. aeruginosa was 0 for patients aged ≤64 and 0.1 for those aged ≥65, indicating a significant difference. Danicopan in vitro For patients with gram-negative bacilli, the DRP-positivity rate was significantly higher for hospitalized patients than outpatients. Thus, in addition to being geriatric, being hospitalized was a risk factor for DRP infection among patients with gram-negative bacilli. All the P. aeruginosa strains isolated were susceptible to colistin. Conclusions Our findings may suggest that once gram-negative bacilli are isolated in an elderly hospitalized patient, possible DRP infection and the topical use of colistin should be taken into consideration even before the results of culture and susceptibility testing are obtained.Interstitial or cornual implantation of the blastocyst is rare, accounting for 2% to 3% of ectopic pregnancies, being considered not viable. The important complications of interstitial pregnancy are uterine rupture and massive bleeding, which usually occur before 12 weeks of pregnancy. The authors report a case of a 36-year-old woman with complaints of transvaginal bleeding and abdominal pain associated with amenorrhea for seven weeks and positive beta-human chorionic gonadotropin (HCG). Transvaginal ultrasound and exploratory laparotomy were performed, confirming the diagnosis of interstitial ectopic pregnancy. The patient underwent a salpingectomy and cornual resection on the left, evolving with clinical improvement and hospital discharge.Encephalopathy with autoimmune thyroid disease (EAATD) is mostly associated with Hashimoto's thyroiditis and has been uncommonly reported with Grave's disease. This case is aimed to report the association of EAATD with thyroid peroxidase (TPO) and thyroid-stimulating immunoglobulin (TSI) antibodies in Grave's disease. We report a 55-year old male who presented with thyrotoxicosis and cerebellar ataxia and was diagnosed with Grave's disease based on clinical and biochemical findings. The patient was managed with anti-thyroid medications with resolution of both thyrotoxicosis and cerebellar symptoms proving the hypothesis that patient's encephalopathy was autoimmune and related to his thyroid disease. High index of suspicion should be maintained for EAATD in patients presenting with neurological deficits with associated clinical and biochemical evidence of autoimmune thyroid disease.Polycystic ovary syndrome (PCOS) is one of the most common causes of subfertility, and it is characterized by hormonal dysregulation like insulin resistance. Various measures have been taken in the past to overcome this insulin resistance to improve fertility treatment outcomes. The current paper aims to review and compare the existing studies and literature to assess the impact of myo-inositol (MI) on oocyte and embryo quality in assisted reproductive technology (ARTs). We thoroughly searched the PubMed and Google Scholar databases by using the keywords "PCOS, polycystic ovarian syndrome, inositol, oocyte quality, embryo quality, assisted conception, ART, IVF, and in vitro fertilization." Nine articles were finalized for review in this paper. Many of the reviewed studies have shown a trend toward the improvement of embryo quality in women with PCOS after MI supplementation; however, there is a lack of statistically significant evidence to support the use of MI in enhancing the quality of oocyte and/or embryo. Clear evidence regarding the role of MI in enhancing the quality of oocyte and embryo in PCOS is limited. A well-controlled, large, randomized controlled trial is required to definitively accept or refute its role.Honey bee envenomations are a common occurrence and cause localized morbidity but rarely cause systemic symptoms or death in humans. Honey bee stingers have a uniquely designed venom sac with a piston-containing bifurcated stinger that can remain in human skin and continue injecting venom after stinging. For some time, it has been proposed that a retained honey bee stinger should be scraped out by a dull edge, as opposed to pinching and pulling out the stinger, in order to minimize the volume of venom injected. We undertook a literature review to evaluate the evidence regarding the effectiveness and safety of methods of honey bee stinger removal. The initial search identified 23 articles of interest; following title and abstract screening, two studies met the inclusion criteria. The included articles used different methods and models to evaluate the relationship between venom injection over time, and one of these studies also compared different methods of stinger removal. The literature review was limited by the small number of studies on the topic, but both included studies include findings relevant to the clinical question of interest. Based on the available evidence, a retained honey bee stinger should be removed as quickly as possible, and there appears to be no disadvantage in doing it by pinching and pulling.Giant cell arteritis (GCA) is an immune-mediated systemic inflammation of large-sized arteries that predominantly affects elderly women. It may be considered as one of the risk factors for acute coronary syndrome (ACS). Moreover, patients with GCA may have increased anticardiolipin antibodies (aCL). However, its relationship with antiphospholipid syndrome (APS) is not clear. We present a case of a unique presentation of GCA with a connection to both ACS and APS. A 76-year-old woman who initially presented to the hospital with a chief complaint of intermittent unilateral headache, blurry vision along with transient aphasia was found to have a biopsy confirmed GCA and subsequently developed left anterior descending artery (LAD) thrombosis. Her hypercoagulability workup was negative except for significantly elevated aCL.Coronavirus disease 2019 (COVID-19) is an acute respiratory viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease outbreak started in China in late December 2019 and quickly spread to the rest of the world, resulting in a pandemic. The incidence of cases is increasing every day, affecting millions of people around the globe and resulting in a public health emergency. Furthermore, disease management has been challenging for the clinicians and other medical personnel in terms of treatment options and availability of personal protective equipment. The off-label use of drugs such as hydroxychloroquine and emergency use authorization of remdesivir can hopefully help the clinicians while treating critically ill patients. The use of convalescent serum has also shown some interim benefit until a definitive treatment and preventive options are uncovered, such as vaccines and other effective treatment regimens.Umbilical hernia is a common cause for patient presentation to the surgeon, often on a nonemergent basis for a bulge at or lateral to the umbilicus but occasionally under emergency circumstances for pain or bowel obstruction when the hernia contents become incarcerated or strangulated. Risk factors for umbilical hernia include female gender, obesity, and ascites. A defect in the abdominal wall fascia at the umbilicus allows the preperitoneal adipose tissue, omentum, or small or large bowel to protrude through the defect. Rarely described is herniation of the appendix through an umbilical hernia, though appendix-containing femoral hernia (de Garengeot hernia) and appendix-containing inguinal hernia (Amyand hernia) are more common. There are 10 available case reports in the medical literature that describe an appendix-containing umbilical hernia; in this case report, we present the 11th case report of appendicitis within an umbilical hernia.A 38-year-old gentleman with no significant past medical history but had recent COVID-19 exposure presented to the hospital with the chief complaints of fever, shortness of breath, and generalized myalgia. He was unfortunately found to be severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive. Laboratory findings showed creatine kinase (CK) >42,670 U/L along with elevated inflammatory markers and unremarkable creatinine, cardiac troponin level. The cause of his rhabdomyolysis was discovered to be due to COVID-19 as he had no evidence of other viral infections, strenuous exercise, seizure, or other nontraumatic exertional etiologies. He received aggressive fluid resuscitation while we trended his CK levels along with other inflammatory markers throughout his hospitalization course. His diffuse myalgia improved with treatments, and he was found to maintain stable hemodynamics and was subsequently discharged home.Cold snare polypectomy is now the preferred technique for resection of most small colorectal polyps. Endoscopists should be aware of a particular mucosal defect after cold snare polypectomy called the wick sign. The wick sign does not represent residual polyp and is not associated with adverse outcomes. Accurate identification is important to prevent unnecessary intervention. A case is presented here with characteristic findings after polypectomy.Locally advanced cutaneous squamous cell carcinoma (cSCC) represents a challenge in treatment. Only very recently (February 2020) have guidelines been released regarding the management of unresectable, locally advanced cSCC. With the introduction of check point inhibitors during the last decade, anti-PD-1 antibodies represent a novel immunotherapeutic strategy in cancer. We present a case of an advanced cSCC not amenable to surgical resection, who experienced dramatic improvement following treatment with the programmed cell death protein 1 receptor (PD-1) inhibitor pembrolizumab as an immunotherapeutic strategy.Autism spectrum disorder (ASD) is a developmental disorder of interpersonal communications and restricted interest and deficits in sensory and social interactions. It co-occurs with anxiety and mostly in 30% of cases related to specific phobia. This review article summarises the sensory association between anxiety and ASD. The role of emotions and neurobiology discussed and sensory over-reactivity (SOR) was related to ASD and anxiety. PubMed database systematically searched for related articles on ASD and anxiety. The keywords used are autism spectrum disorder, autism spectrum disorder and emotion, anxiety disorder, sensory in autism and anxiety, and psychopathology. The results were most significant and related to the sensory association between ASD and anxiety. Out of 19 studies discussed, there were eight systematic reviews with meta-analysis, seven systematic reviews, three traditional reviews, and one included both systematic reviews with randomized controlled trials (RCTs). However, due to possible limitations and considerations, like small sample size and few clinical trials; hence, further recommendations to randomized clinical trials and cohort studies warranted.
