Introduction Many studies have suggested a link between vitamin D deficiency and the development of other atopic diseases like allergic rhinitis (AR). AR can lead to sleep disturbance, fatigue, depressed mood, and compromised cognitive function, which can impair the quality of life and productivity in many people. Objective We aimed to determine the association between vitamin D levels and AR and the effect of vitamin D on atopy markers. Methods All patients with AR who were diagnosed, treated, and followed up at the King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia from January 2012 to January 2020 were included in the study. Our exclusion criteria were as follows pediatric patients, patients with insufficient follow-up data, patients with no atopy markers, patients with comorbid conditions affecting their serum vitamin D levels, and patients with a history of taking medications that affect serum vitamin D levels. Results Fifty-five adult patients with AR were included in the study. Patients with vitamin D deficiency were more likely to have uncontrolled AR. Regarding the effect of vitamin D deficiency on atopy markers, there was no statistically significant relationship between vitamin D deficiency and serum immunoglobulin E (IgE) levels. However, serum eosinophil levels were significantly higher in patients with vitamin D deficiency. Conclusion Our results showed that vitamin D deficiency is strongly associated with uncontrolled AR; there was a statistically significant relationship between vitamin D deficiency and eosinophil levels, but no significant relationship between vitamin D deficiency and serum IgE was found.Immunoglobulin G4-related disease (IgG4-RD) is a new disease entity of rare and complex immune-mediated fibroinflammatory conditions that can affect any organ. The concomitance of IgG4 sclerosing sialadenitis and dacryoadenitis with rhinosinusitis is extremely rare. We report a case of IgG4 sclerosing sialadenitis and dacryoadenitis (Mikulicz's disease) diagnosed in a middle-aged African American man with a long-standing history of chronic rhinosinusitis who presented with progressively worsening bilateral salivary and lacrimal glands swelling. Imaging revealed pansinusitis, symmetric enlargement of the lacrimal glands, parotid glands, and submandibular glands. Serological IgG4 level was significantly elevated and the diagnosis of IgG4 sclerosing sialadenitis was confirmed by histopathology. A robust clinical response in the facial swelling and nasal manifestations was noted after the initiation of immunotherapy with corticosteroids.Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect nearly every organ system. The 2019 European League Against Rheumatism and American College of Rheumatology (EULAR/ACR) SLE have proposed an additive, weighted multicriteria system for classifying SLE while using antinuclear antibody (ANA) as an entry criteria. Most patients with SLE will test positive for ANA. We report a 28-year-old half Caucasian and half Asian male patient who initially presented with malar rash, severe bilateral lower extremity edema, and proteinuria. Typical serological tests associated with SLE were negative.  https://www.selleckchem.com/products/piperaquine-phosphate.html  The diagnosis of seronegative lupus nephritis was made with kidney biopsy that revealed class IV and V lupus nephritis. Creatinine improved from 2.06 to 0.87 mg/dL with oral mycophenolate mofetil (MMF) and a tapered dose of glucocorticoids. This case highlights the difficulty of diagnosis and treatment of seronegative lupus nephritis.Digital communication has revolutionized the way children interact and maintain social relations. However, not every tween (8-12 years) or teen (13-18 years) is able to take full advantage of digital media and may cross personal and social boundaries causing distress, mostly to their own friends at school and beyond. This results in adverse health effects for both the cyberbullying perpetrator and the victim. Articles reviewed on elementary school children and adolescents, collected from two different databases, showed that the number of elementary school kids using smartphones has more than doubled in the past few years. Given this rise, the risk of cyberbullying has also increased. Not all elementary school kids have the required media literacy to understand that their friends have equal rights in the virtual world as they do in the schoolyard. Regardless, they still carry a smartphone with data, use computers, and other electronic media to bully, embarrass, exclude, or humiliate others, often through social networking sites. Moving from tweens to teens seems to worsen the cyberbully behavior and choices, with middle school kids facing the highest cyberbullying incidents followed by high school kids and then the elementary school kids. The anonymity of cyberspace and the perceived lack of consequences seems to embolden the cyberbully. Identifying the mindset of a cyberbully and those at high risk of becoming a cyberbully can help target intervention efforts where they are needed the most and prevent cyberbullying.Shewanella species are opportunistically pathogenic, gram-negative bacilli that are part of marine microflora. Infection caused by Shewanella species in humans is rare and mostly acquired after direct contact with seawater or ingestion of raw seafood. The exact pathogenesis remains unclear. Cutaneous infections are among the most common manifestation with underlying skin diseases and immune-compromised states; however, bacteremia from lungs, abdominal, and biliary sepsis has also been reported. These infections are difficult to diagnose due to limited physicians' experience and scarce microbiological data available. Hence, delayed diagnosis and treatment could be fatal and may result in sepsis with multi-organ failure. Our case report reiterates the fact that careful attention should be devoted to unusual circumstances in history and atypical pathogens on cultures if there is no or minimal clinical improvement after antibiotics.Introduction Superior mesenteric artery (SMA) or Wilkie's syndrome is a rare condition arising due to compression of the third part of the duodenum between the abdominal aorta and the superior mesenteric artery. It is important to explore factors which help in suspicion and early diagnosis of the condition. The aim of this study was to find out if measurements of aortomesenteric angle and distance can predict the occurrence of SMA syndrome. Another objective was to find out if the BMI was correlated with the aortomesenteric angle and distance of the patients. Methods A retrospective hospital-based case-control study was conducted in Qimat Rai Gupta Central hospital, Haryana, India from 2018-2020. Out of total 2100 records of acute and chronic abdominal pain patients, only seven cases of Wilkie's syndrome were confirmed via Contrast-Enhanced Computed Tomography (CECT). Information on age, gender, BMI, duration of symptoms, clinical presentation, aortomesenteric angle, and distance was compared among three groups Group I-SMA syndrome patients (N=7), Group II- acute abdominal pain patients (N=14) and Group III- chronic abdominal pain patients (N=14).
