Although numerous and varied drugs have been associated with DIP, the clinical evidence on doxycycline-induced pancreatitis is sparse. Case Report: We present the case of a 58-year-old female who presented with complaints of nausea and severe epigastric pain. Her medications included doxycycline which she had been on for only 2 days. Computed tomography of her abdomen showed mild enlargement of body of the pancreas with peripancreatic fatty infiltration, along with lipase level suggestive of acute pancreatitis. In the absence of classical risk factors for acute pancreatitis, a diagnosis of DIP secondary to doxycycline therapy was made. Immediate withdrawal of the drug was accompanied by relief of symptoms and resolution of pancreatitis. Conclusion: This report implicates doxycycline as an etiological factor for acute pancreatitis. Knowledge regarding doxycycline related pancreatitis is of paramount importance in order to diagnose cases early and institute effective treatment in patients who are undergoing therapy with this drug.","PeriodicalId":19703,"journal":{"name":"North American Journal of Medical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85328637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Case Report: We present a case of an 18-year-old female who presented with exertional shortness of breath, fatigue, and recurrent lower respiratory tract infections. She had unremarkable physical examination but chest x-ray showed an abnormal opacity next to right heart border. Computed tomography (CT) chest was performed that showed possible scimitar syndrome. Transesophageal echocardiogram (TEE) and right heart catheterization (RHC) confirmed the diagnosis. Conclusion: Scimitar syndrome is a very rare congenital anomaly of pulmonary venous return. It is usually diagnosed in early childhood but the diagnosis may be delayed until later in adulthood. The consequences are pulmonary hypertension, right-sided heart failure, and frequent pulmonary infections resulting in increased morbidity, mortality, and frequent doctor visits for otherwise healthy young patients.","PeriodicalId":19703,"journal":{"name":"North American Journal of Medical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84521650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clear evidence to support the link between 25-hydroxyvitamin D levels and OA is lacking. Aim: To describe the association of serum 25-hydroxyvitamin D status in patients with OA in the primary care office. Materials and Methods: We reviewed the records of 1,455 patients seen in our primary care office between November 2013 and October 2014. All patients were older than 18 years and had a diagnosis of OA. Demographic characteristics as well as 25(OH)D levels and comorbidities were analyzed. Results: Levels of 25(OH)D were available in 1,222 patients with OA. Fifty-one percent of the patients had a low 25(OH)D level. Patients with OA and low 25(OH)D were on an average 5 years younger than patients with OA and normal 25(OH)D (P < 0.001). African Americans (71.7%) and Hispanics (63.1%) had a higher prevalence of low 25(OH)D compared to Whites (42.9%) and other races (49.1%) (P < 0.001). There were significantly more smokers (15.4%) and patients with type 2 diabetes (27.6%) in the group of patients with osteoarthritis and low 25(OH)D (P < 0.001). A lower prevalence of hypothyroidism (18.5% versus 27.4%) and higher body mass index (BMI) were also noted in the group of interest. Conclusion: Patients with low levels of 25(OH)D and OA are younger than their counterparts with low 25(OH)D level.

Mast cell degranulation and histamine release are of central importance in the pathogenesis of CU. About 40-50% of the patients with chronic idiopathic urticaria (CIU) or chronic spontaneous urticaria (CSU) demonstrates an immediate wheal and flare response to intradermal injected autologous serum. This led to the concept of autoimmune urticaria (AIU). Aims: To determine the occurrence, clinical features, associated clinical conditions, comorbidities of AIU, and to compare this with CSU. This study aimed to find the frequency of autologous serum skin test (ASST)-positive patients among patients with CSU and to identify the clinical and laboratory parameters associated with positive ASST and to compare the treatment outcome. Materials and Methods: A prospective correlation study in 110 patients with CSU was conducted, after screening 200 CU patients attending the outpatient Department of Dermatology during from January 2012 to May 2013. Patients were subjected to ASST, complete blood counts, urine routine examination, liver function tests, renal function tests, thyroid function tests (T3, T4, and TSH), and urine analysis. Results: Out of 200 CU patients screened, 90 patients had excludable causes based on detailed history and skin prick test, and the remaining 110 patients were considered to have CSU. These 110 patients were further subjected to ASST, serum immunoglobulin E (IgE), and peripheral blood eosinophilia. ASST was positive in 48 patients and negative in 62 patients. Frequency of urticarial attacks and associated diseases such as abnormal thyroid function tests in both ASST-positive and ASST-negative patients did not show any statistical significance. Only attacks of angioedema in ASST-positive individuals were higher and were statistically significant. In the ASST-positive group, 31 (81.25%) patients showed improvement with first-line antihistamines, along with oral prednisolone and injection Histaglobulin and 10 (10.41%) patients did not show any improvement. Thirty-three (43.54%) patients in the ASST-negative group showed improvement while 13 (30.62%) patients did not show improvement. Conclusion: ASST is considered a screening test for AIU, which decreases the rate of diagnosis of \"idiopathic\" form of CU. ASST-positive patients in addition to antihistamines, were treated with short course of oral steroids and weekly Histaglobulin injections for 5 weeks followed by the 3 rd and 6 th months.","PeriodicalId":19703,"journal":{"name":"North American Journal of Medical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79286934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, when we puncture pancreatic cystic lesions, we should consider not only pathological evaluation but also fluid analysis.[4] Some of these issues are still controversial although there are many articles about them. Recently, EUS-guided, through-the-needle confocal laser-induced endomicroscopy and cystoscopy for pancreatic cystic neoplasms have been reported.[5] In this way, EUS-FNA will be developed and its use will spread all the more. Jani et al.[6] reviewed the present status of EUS-FNA of pancreatic lesions systematically.

Proinflammatory cytokine levels in plasma were measured by enzyme-linked immunosorbent assay (ELISA), and concentrations of circulating immune complexes (CICs) were analyzed by C1q solid phase method. Furthermore, food-specific immunoglobulin G (IgG) and immunoglobulin E (IgE) levels were determined in the CIA model. Results: In the CIA model, we found that levels of tumor necrosis factor-alpha (TNF-a), interleukin (IL)-1, IL-6, and IL-17, as well as CICs, were elevated significantly.
