Mixed connective tissue disease (MCTD) is a rare autoimmune condition that shows an overlap of at least two connective tissue diseases (CTD) including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), scleroderma, Sjögren's syndrome, polymyositis, or dermatomyositis. From a laboratory standpoint, MCTD is associated with high titers of anti-U1-RNP antibodies, which makes it difficult to determine whether it is a variant of each of the respective CTDs or a different entity altogether. Our objective is to report the case of a patient with MCTD presenting with status epilepticus who was ultimately diagnosed with lupus cerebritis. The case also highlights the development of complications unrelated to MCTD that made the management even more challenging. Overall, the authors emphasize the rareness of lupus cerebritis as a presentation, the diagnostic challenges faced due to the lack of classical manifestations of SLE, and how the complicated clinical course makes a downhill prognosis more likely., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Leitao et al.)

Aortic dissection (AD) is a serious condition, which typically affects men more than women. Strongly established risk factors include uncontrolled hypertension, connective tissue disorders, advanced age, cocaine use, and aortic injury. We believe it's important to report this case due to the occurrence of Stanford type A AD in a healthy 40-year-old male devoid of genetic, medical, family, and environmental risk factors. This patient presented with a tearing anterior chest pain radiating to the back and was promptly diagnosed and managed with surgical replacement and grafting of the diseased aorta and its involved branches. Therefore, it is imperative to include AD as a differential in atypical case scenarios and case presentations, as missed and delayed diagnosis and management would worsen the clinical outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Jain et al.)

Human immunodeficiency virus (HIV) associated opportunistic infections are complications of patients with advanced HIV infection who are unaware of their disease or non-compliant with antiretroviral therapy. HIV patients with low CD4 count, generally less than 200 cells/μL, are at risk of developing opportunistic infections. We report a case of a 53-year-old male diagnosed with opportunistic infections, Toxoplasma gondii and cytomegalovirus (CMV). His initial presentation was central nervous system Toxoplasmosis and he later developed CMV colitis. Both are consequences of his undiagnosed advanced HIV status. The patient was promptly treated with appropriate medications for both conditions. The patient's HIV status is well controlled with highly active antiretroviral therapy (HAART) and his CD4 count is improving. It further exhibits the significance of adequate screening protocols and the importance of early treatment for HIV patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Emuze et al.)

Nickel, a silvery-hard metallic element used in corrosion-resistant alloys, is widely used in the medical field. Nickel has aided in medical advancements; however, it has been known to cause hypersensitivity reactions. Retained foreign bodies due to surgical procedures may cause postoperative complications such as allergic reactions. This case involves a 30-year-old female presenting with non-specific symptoms involving multiple organ systems, notably with abdominal pain. Due to chronic symptoms, the patient was tested for metal allergies and diagnosed with hypersensitivity reactions to nickel surgical clips that were previously inserted during cholecystectomy. Subsequently, the patient had surgical removal of the foreign bodies, which led to significant improvement of her symptoms immediately. This case demonstrates a delayed hypersensitivity reaction to a foreign body involving multiple body systems and vague symptoms making the diagnosis challenging. It is important to carefully evaluate the patient's past medical history including history of any allergies. It also brings attention to the necessity of performing metal skin patch tests preoperatively for individuals with a history of any type of allergies., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Luvsannyam et al.)

Acute limb ischemia (ALI) is the sudden decrease in limb perfusion caused by embolism secondary to many blood stasis conditions. Treatment commences with intravenous (IV) unfractionated heparin infusion. Individuals can have an immune-mediated reaction to heparin products which results in heparin-induced thrombocytopenia (HIT). Coronavirus disease 2019 (COVID-19) has added to the difficulty of treating patients with ALI due to increasing the likelihood of HIT via the virus's ability to manipulate the coagulation parameters. We present a case of ALI complicated by HIT in a 49-year-old male with a confirmed asymptomatic COVID-19. The patient initially presented with progressive pain, coldness, and tingling in the right foot. He was treated with a tissue plasminogen activator (TPA) and a heparin drip. The occlusion persisted despite medical intervention leading to right below-knee amputation. The patient returned to the emergency department (ED) 13 days later with massive intracranial hemorrhage and subsequently expired. This case study demonstrates the significance of COVID-19 diagnostic testing due to the possibility of developing blood clots and potential complications, including HIT., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Siddiqui et al.)

Bariatric surgery is one of the most successful treatment options for morbid obesity and related comorbidities that is reserved for patients when lifestyle modifications and medical treatments fail. Bariatric surgeries are proven to result in weight reduction and improve obesity-related complications; however, there still are some reported failures. We report the case of a 35-year-old woman with morbid obesity and diabetes mellitus who had failed laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG) when done individually. The patient finally had a successful weight loss after undergoing revision LAGB over LSG. Although the present literature reports LAGB being an unsuccessful weight loss procedure, this case highlights the significance of LAGB as an effective bariatric surgery compared to other procedures. Our patient not only lost her weight successfully but also resolved her comorbid conditions and mental illness following the LAGB., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Luvsannyam et al.)

Leiomyomas, also known as uterine fibroids, are the most common benign uterine tumors in women. The most frequently reported symptoms are uterine bleeding and abdominal and/or pelvic pressure; however, most cases are asymptomatic and may be found incidentally. Endometriosis is a condition where the endometrium proliferates outside of the uterine cavity. Extrauterine endometrial implants are usually found in the ovaries, pelvis, and peritoneum, but can extend anywhere throughout the body. Women with endometriosis may exhibit dysmenorrhea, dyspareunia, dyschezia, and infertility. Inflammation caused by endometriosis may lead to fibrosis, scarring, and adhesions. We report a case of an asymptomatic 36-year-old African-American woman with increasing abdominal girth, consistent with a 28-week gestation, presenting to her obstetrician/gynecologist for her annual exam, who on further investigation is found to have multiple large fibroids, bilateral ovarian cysts, and widespread endometriosis with several adhesions ultimately leading to a frozen pelvis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Wazir et al.)

Mucinous cystadenomas are among the most common benign ovarian neoplasms. They are known for their massive size causing compressive effects ranging from pressure, pain, bloating, and urinary symptoms. Over time, these adnexal masses can lead to fatal complications, such as ovarian torsion or hemorrhage. Incidental findings of these tumors are common as many of these patients are asymptomatic. Pelvic examinations and imaging studies can be used to further diagnose symptomatic patients and aid physicians in developing an appropriate course of treatment. We report a rare case of a large mucinous cystadenoma, with a size of 25 × 25 cm and concurrent management of postmenopausal bleeding. We present the data from the admission of the patient to her discharge, including history and physical examination, diagnostic reports, transabdominal ultrasound, CT scan, surgical evaluation, and surgical-pathology reports. Abdominal pain can present in a variety of different scenarios, and ovarian masses only represent a small portion of the differentials. Mucinous cystadenomas constitute an even smaller percentage of these ovarian growths. As discussed in this case report, a large ovarian mucinous cystadenoma was compressing the surrounding structures resulting in a wide array of symptoms. The case describes the importance of extensive diagnostic evaluation and prompt surgical management of these ovarian tumors. It also brings attention to the significance of diagnosing a medical condition such as postmenopausal bleeding promptly to avoid potential negative outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Somagutta et al.)
