Importance Migraine is a highly prevalent disorder associated with cardiovascular diseases. Cardiovascular diseases are also associated with preeclampsia (PE). The adverse pregnancy outcomes PE, preterm birth (PTB), low birth weight (LBW), small for gestational age (SGA) and placental abruption share aspects in their pathophysiology, which are also found in patients with migraine, such as inflammatory stress and hypercoagulability. Objective To determine the association of adverse pregnancy outcomes including PE, PTB, LBW, SGA, and placental abruption with a history of migraine through a systematic review and meta-analysis. Evidence Acquisition MEDLINE (PubMed), the Cochrane Library, and EMBASE, were searched from inception to November 11, 2018. Cohort studies and case-control studies evaluating migraine history and pregnancy complications were eligible. Results Of 1388 screened references, 14 studies were included in the systematic review. There were higher risks of PE (odds ratio [OR], 2.07; 95% confidence interval [CI], 1.51-2.85; I2 = 76%) and LBW (OR, 1.18; 95% CI, 1.03-1.34; I2 = 9%) in women with migraine compared with women without migraine. We observed no significant association between history of migraine and PTB (OR, 1.23; 95% CI, 0.97-1.55; I2 = 61%) or SGA (OR, 1.06; 95% CI, 0.98-1.15; I2 = 0%). Conclusions A history of migraine is significantly associated with an increased risk of adverse pregnancy outcomes including PE and LBW. We hypothesize that shared pathophysiology due to underlying preclinical cardiovascular risk in women with migraine might play a role during pregnancy. Relevance Pregnant women with a history of migraine should be considered at higher risk of adverse pregnancy outcomes and should be informed, monitored, and treated preventively accordingly. Target Audience Obstetricians and gynecologists, family physicians. Learning Objectives After completing this activity, the learner should be better able to: Describe the association between migraine and placenta-induced pregnancy complications; Explain the possibility of the developing preeclampsia in women with a history of migraine; and Assess the risk of preterm birth or a neonate with low birth weight or small for gestational age in women with migraine.

Background Equipoise exists regarding sickle cell disease (SCD) as a risk factor for COVID-19 disease severity and variables that increase risk of COVID-19 severity in SCD. Given our health system's large SCD patient catchment, we analyzed our own experience in this regard. Study methods Retrospective analysis of the clinical course and factors associated with need for hospitalization and ICU admission of SCD patients diagnosed with COVID-19 through the Northwell Health system from March 1 to Dec 31, 2020. Results Of 1098 patients with SCD, 3.3% were diagnosed with COVID-19. Overall rates of hospitalization, ICU admission, cohort mortality, and in-hospital mortality were 80%, 19%, 2.5%,and 3.1%, respectively. By multivariable analysis, hospitalization risk was decreased by 60% for every 1 g/dL increase in admission Hb. ICU admission risk was increased by 84% as a health care worker; increased by 45% for every 1000/uL increase in admission immature granulocyte count; and decreased by 17% with hydroxyurea use. Discussion High hospitalization rates are compatible with worsened severity upon COVID-19 infection in SCD compared to the general population. Patients should be placed on hydroxyurea to increase their Hb and perhaps lower their neutrophil counts. Health care workers with SCD may warrant special safety precautions.

Casestudy Exophiala dermatitidis is a dematiaceous mold that is associated with subcutaneous, central nervous system and pulmonary infections; osteomyelitis; and disseminated disease. Isolation of E. dermatitidis from patients with mild symptoms may be difficult to interpret whether is a contaminant or asymptomatic patient with serious infection. However, it is important to diagnose asymptomatic patients early in the stage because of up to 25% mortality rate. Results 77-year-old male with history of chronic obstructive pulmonary disease presented to his pulmonologist with cough. He was started on azithromycin and steroids. His cough worsened and he was transitioned to levofloxacin with continuation of steroid treatment. In addition, he developed fatigue, weakness, poor appetite, chills and nights sweat along with some urinary complaints. His chest X-ray showed infiltrates and he was diagnosed with left lower lung pneumonia and urinary tract infection and was treated with doxycycline and ciprofloxacin. Blood cultures were drawn. Additional past medical history was not significant. Blood culture became positive on day 4 of incubation. Gram stain showed yeast-like cells, but the blood culture multiplex PCR was negative. Serum cryptococcus antigen was negative. Three days later, a dark shiny olive-colored colony with dark obverse side was isolated. It grew at 42 C. Microscopic examination revealed hyaline and pigmented hyphae with brown conidia. It was identified as Exophiala dermatitidis and confirmed by the state public health laboratory. Blood cultures drawn after hospital admission remained negative. Patient’s symptoms improved with antibiotic treatment. Therefore the clinicians believed that the E. dermatitidis was a probable contaminant and patient was discharged with follow-up. During the follow-up process he developed respiratory infection with Coronavirus (HKU1, NL63, 229E, OC43). Follow-up continues. Conclusion Blood cultures are not sensitive for mold infection especially for an uncommon contaminant like E. dermatitidis, it may be difficult to decide whether a positive culture is a real result or not. Fungal antigen tests such as beta-D-glucan test may be helpful in distinguishing between invasive infection and contaminant. Additionally, we believe that in our case, steroid use could have caused a temporary immunosuppression and led to Exophiala dermatitidis infection.

Introduction/Objective H antigen is a precursor for A and B antigens and is mostly converted except for the O blood group, which has the highest amount of H antigen. I is present on all adult RBCs. Anti-IH is usually an IgM antibody active at cold temperatures, and rarely demonstrates a wide thermal amplitude and can cause a significant hemolytic transfusion reaction. Methods Data was collected from patient information and transfusion management systems. Results 38 year old female with sickle cell disease presented to the emergency room with dizziness, tachypnea and Hgb: 5.9 g/dl Hct:19.1%. Upon further review, patient chart showed that she had received an emergency RBC exchange transfusion 21 days prior to this admission for acute chest syndrome. She was B positive. The units for RBC exchange consisted of 5 group B and 1 group O units and an additional 1 group O unit later. All RBC units were matched for her phenotype; Rh, K, Duffy & Kidd, except anti-S which was ruled out. At the time of discharge, Hgb was 9.3 g/dl and Hct was 27.7%. The drop in Hgb between discharge and the present admission prompted a suspicion for delayed hemolytic reaction/hyperhemolysis. The sample sent to the local Reference Laboratory came back as follows: DAT/Coombs Positive, DAT C3 positive; positive for cold auto-anti-IH antibody. A thermal amplitude test indicated that the anti-IH was reactive at 30 C and therefore had the potential to be of clinical significance. Her Hgb continued to drop and 3 days later Hb=3.7 g/dl with instructions not to transfuse unless clinically emergent. With treatment of IVIG and steroids, reducing further blood draws and monitoring the patient for clinical symptoms only, her Hgb/Hct started to rise and the patient was discharged 4 days later with Hgb: 6.4 g/dl, and no symptoms of anemia. Conclusion Our case study is important in two ways: Firstly, it raises awareness of the severity of a cold autoantibody, i.e. anti-IH, with a wide thermal amplitude. Specifically, in this case, our attempt to provide phenotypically similar RBCs resulted in the destruction of all the type O donor cells as well as some of the B donor cells. Secondly, even with Hgb counts as low as 3.7, treating the patient and not the number proved to be better clinical practice. In conclusion, a good monitoring protocol for sickle cell patients is required to transfuse less and avoid serious complications.

Introduction/Objective Synovial-like metaplasia is well known to accompany breast implants, but it can also rarely be found in the endometrium, associated with intrauterine devices. We present two cases of endometrial synovial-like metaplasia. Methods The hysterectomy specimens were diagnosed at Northwell Health and reviewed at the departmental Consensus Conference. Immunostains for cytokeratin AE1/AE3 were performed on the endometrium. The histopathologic findings were correlated with the clinical information. Results Both patients had had intrauterine devices placed for birth control. One, a 47-year-old female with a family history of Lynch syndrome and newly diagnosed with a corresponding mutation, underwent prophylactic hysterectomy. The second patient, a 50-year-old female with a history of uterine prolapse, was experiencing stress urinary incontinence, for which she underwent supracervical hysterectomy. Both patients had intrauterine devices in place at the time of hysterectomy. Both uteri showed endometrial synovial-like metaplasia. It was associated with a complete absence of the endometrial surface epithelium. The synovial-like cells were eosinophilic, plump and elongated, were palisaded perpendicular to the endometrial surface and were negative for cytokeratin AE1/AE3, which immunostain also confirmed the absence of the endometrial surface epithelium and the presence of some residual deeper endometrial glands. Conclusion Endometrial synovial-like metaplasia is a rare entity described in patients with intrauterine devices. The mesodermal-derived endometrium is apparently able, when exposed to a semi-mobile foreign body, to develop a way to minimize friction by mimicking synovium, similar to the connective tissue facing breast implants. Such surface must be better at withstanding chronic friction than the regular endometrial epithelial surface, leading to this unusual and fascinating change. Since the resulting surface mimics synovium perfectly, both morphologically and immunohistochemically, and serves a very similar mechanical purpose, we propose to call this phenomenon, wherever it is found, “synovial metaplasia” instead of the current term “synovial-like metaplasia.”

Objective To determine the relationship between adenoidectomy and/or tonsillectomy in childhood and allergic diseases in adulthood. Materials and Methods A survey investigating the history of adenoidectomy and/or tonsillectomy was administered to patients that were followed-up by our department between January and June 2014 with the diagnosis of asthma, allergic rhinitis, urticaria-angioedema, drug allergy, food allergy, and venom allergy; patients willing to participate were included in the study. The relationship and risk ratios were analyzed. Results Totally, 510 (female/male: 379/131) patients were included in the study: 248 with asthma, 205 with rhinitis, 82 with drug allergy, 73 with urticaria, 24 with food allergy, and 14 with venom allergy. Of these, 65 (12.7%) had undergone adenoidectomy and/or tonsillectomy. Of these 65 patients, 41 had asthma, 33 had allergic rhinitis, and 28 had other allergic diseases. No relation between the history of atopy and adenoidectomy and/or tonsillectomy (p=0.129) was detected; however, there was a positive correlation between asthma and patients aged

Background The prevalence of allergic reactions due to bee stings in beekeepers varies in different regions of the world. The aim of this study was to evaluate the characteristics of sting reactions and the risk factors for developing systemic reactions in Turkish beekeepers. Methods A self-administered questionnaire was distributed to 1250 beekeepers to be completed in seven different cities of Turkey. A total of 494 (39.6 %) questionnaires were returned. Results There were 444 subjects (89.9 %) with a history of sting exposure in the previous 12 months.Systemic reactions were present in 29 subjects (6.5 %) and nine (2 %) reactions were anaphylactic. Fifty-five percent of beekeepers reported more than 100 bee stings in the previous year. When systemic reactions were controlled by age and duration of beekeeping in a logistic regression model, seasonal rhinitis (OR: 4.4, 95 % CI: 1.2-11.5), perennial rhinitis (OR: 4.6, 95 % CI: 1.2-18.2), food allergy (OR:7.0, 95 % CI: 2.0-25.0), physician-diagnosed asthma (OR: 8.0, 95 % CI: 2.5-25.6), having an atopic disease of any type (OR: 3.3, 95 % CI: 1.2-8.7) and having two or more atopic diseases (OR: 10.9, 95 % CI: 3.5-33.8) were significantly associated with systemic reactionsdue to bee sting in the previous 12 months Conclusion The incidence of systemic reactions in Turkish beekeepers is low, which might be due to the protective effect of a high frequency of bee stings. The risk of systemic reactions increases approximately three-fold when one atopic disease is present and eleven-fold when two or more concurrent atopic diseases are present with respect to no atopic disease.
