Non-traumatic Thoracic Aortic Dissection in a Healthy Patient.

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.

Meniscus Tear: Pathology, Incidence, and Management.

Meniscus tears are a common orthopedic pathology and planning a single, effective treatment is challenging. The diagnosis of meniscal tears requires detailed history-taking, physical examinations, special diagnostic tests, and most likely magnetic resonance imaging (MRI) to confirm the lesion. A good understanding of the meniscal structure including vascularity, zones, function, and affected movements with associated symptoms plays a crucial role in establishing an optimal management plan. A careful assessment of the patient's characteristics, comorbidities, post-repair rehabilitation, and patient's overall function and satisfaction are also important for ideal management. While conservative management is commonly implemented and the only option for certain patients, partial meniscectomy remains to be the most performed treatment procedure. However, partial meniscectomy is no longer the first-line therapy due to the limitation of certain patient characteristics and side effects in the long run. Instead, meniscal repair has been shown to have better long-term outcomes and is therefore recommended for all tears, especially for young patients with acute traumatic lesions. Tissue engineering has been of high interest in the current research with promising therapeutic results. This review critically evaluates and compares the management of meniscal tears with surgical versus comprehensive management using the current literature.

Lupus Cerebritis as a Rare Neuropsychiatric Manifestation of Systemic Lupus Erythematosus.

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.

Fournier's Gangrene in a Female Diabetic Patient: A Case Report.

Necrotizing fasciitis is a rare but potentially fatal deep infection involving subcutaneous tissue and fascia. The infection can occur in all parts of the body and can cause acute onset pain, swelling, fever, malaise, and tachycardia with or without evidence of skin inflammation. Risk factors include recent surgery, diabetes, trauma, intravenous drug use, alcoholism, and chronic illnesses. This case involves a 35-year-old female with a past medical history of hypertension, type II diabetes mellitus, and obesity presenting with a painful vulvar lump, which progressed rapidly into extensive necrotizing soft tissue infection despite the incision and drainage of the vulvar abscess, marsupialization, and antibiotic therapy. The patient underwent multiple surgical debridements with intense medical treatment and wound vacuum-assisted closure therapy. Uncontrolled diabetes and obesity significantly increase the risk of necrotizing fasciitis. Fournier's gangrene should be suspected in patients with comorbid conditions and a presentation of a urogenital abscess. This case highlights the importance of prompt diagnosis and treatment of necrotizing fasciitis in a timely manner.

Neurobiology of Schizophrenia: A Comprehensive Review.

Schizophrenia is a debilitating disease that presents with both positive and negative symptoms affecting cognition and emotions. Extensive studies have analyzed the different factors that contribute to the disorder. There is evidence of significant genetic etiology involving multiple genes such as dystrobrevin binding protein 1 (DTNBP1) and neuregulin 1 (NRG1). There is no clear link between neurotransmitter changes and the pathophysiology of schizophrenia; however, studies have shown that subcortical dopamine dysfunction is the key mechanism. Specific regions of gray and white matter changes are observed in patients with schizophrenia; gray matter changes being more significant after the onset of psychosis. These pathological changes may be implicated in the impairment of executive functioning, attention, and working memory. The disease can be managed with pharmacological treatments based on individual patient profile, patient compliance, and disease severity. The challenge of disease management sometimes persists due to the side effects. A better understanding of the pathological processes in schizophrenia may lead to more specific and effective therapies.

Sodium glucose co-transport 2 inhibitors for gout treatment.

Hyperuricemia remains the most prevalent cause of gout. Gout patients present with joint inflammation and uric acid crystals deposition manifesting as tophi. The association of gout with increased risk of insulin resistance, diabetes, metabolic disorders, increased cardiometabolic risk, and kidney disease is well established. These factors influence the treatment plan, and current treatment options have limited cardiovascular risk reduction. So the need for novel treatments with a broad range of coverage for the complications is warranted. Sodium-glucose co-transporter 2 inhibitors are novel drugs approved for treating type-2 diabetes. They prevent glucose reabsorption and lower serum uric acid levels. Recently few studies have studied their association with reducing the risk of gout. They may help address the gout related complications through their recorded benefit with weight loss, improved insulin resistance, and cardiovascular benefits in recent studies. . SGLT2-Is may be useful to reduce the risk of gout in individuals with type 2 diabetes. Limited literature is available on the safety and efficacy of these novel antidiabetic drugs in patients with gout. This review is aimed to summarize the current knowledge on the role and effectiveness of novel antidiabetic medication as an early therapeutic option in gout patients.

Hyperlipidemia and Statin Use on the Progression of Osteoarthritis: A Systematic Review.

Osteoarthritis (OA) is progressive wear and tear disease that affects multiple joints, including knees, hips, and spine. OA causes structural damage to joints. Although hypertension, type II diabetes, and hyperlipidemia have a silent effect, for the most part, the addition of osteoarthritis has a limiting and debilitating impact on patients. Common symptoms of OA include joint pain, joint swelling, limitations in range of motion that is impacting one's quality of life. The question being investigated in this systematic review is whether hyperlipidemia or the use of statin has any effect on osteoarthritis and progression of osteoarthritis. This systematic review of 13 articles was done to explore if there is an effect of hyperlipidemia and statin use on the progression of osteoarthritis. This study included 6,974,538 total participants. Eight studies out of the 13 investigated the effect of statin use. Out of the 13 articles, five studies investigated the impact of lipid levels on OA. The total participants cannot be divided into statin users and non-users because some studies did not divide the participants into two groups. Studies that investigated the effect of lipid levels on OA were studied based on age. Some included only women in their study, and one study was solely conducted in the military population. Therefore, these studies cannot be divided based on age. Further research is needed to significantly conclude either the positive or negative correlation of hyperlipidemia and statin use on osteoarthritis and its progression.

Central Nervous System Toxoplasmosis and Cytomegalovirus Colitis in an Asymptomatic HIV Positive Patient.

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.

Revision Laparoscopic Adjustable Gastric Band as a Successful Alternative Over Sleeve Gastrectomy After Failed Initial Weight Loss Therapies.

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.

Acute Limb Ischemia Complicated by Heparin-Induced Thrombocytopenia in an Asymptomatic COVID-19 Patient.

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.

Diffuse Nickel Hypersensitivity Reaction Post-cholecystectomy in a Young Female.

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.

A Rare Case of Three Distinct Gastrointestinal Neoplasms Occurring Simultaneously in an Elderly Patient.

Duodenal adenocarcinoma (DA), gastrointestinal stromal tumor (GIST), and pancreatic neuroendocrine tumor (PNET) are a set of rare gastrointestinal (GI) cancers characterized by nonspecific symptoms such as anemia, weight loss, and abdominal pain. We report an interesting case of DA, GIST, and PNET in a 79-year-old African American male who presented to the emergency department with syncope. The patient was tachycardic and found to have severe anemia. Further computed tomography (CT) of the abdomen and pelvis with contrast revealed a mass within the duodenal bulb along with a pancreatic cystic lesion. The patient underwent gastroduodenectomy and distal pancreatectomy with incidental findings of GIST in the posterior gastric wall. The patient after surgical removal of all tumors no longer experienced abdominal pain and had hematocrit and hemoglobin (H&H) level of 9.1/31.7 postoperation day (POD) 14. The case unfolds a rare presentation of three neoplasms that were moderate to well-differentiated with no metastases. It highlights the importance of assessment of rare GI neoplasms concurrently with colorectal cancer when geriatric patients present with nonspecific GI symptoms.

Delayed Titanium Hypersensitivity and Retained Foreign Body Causing Late Abdominal Complications.

Titanium is a known metal used widely in the medical field and can cause allergic reactions with complications. Our case is about a 28-year-old female presenting with a spectrum of abdominal symptoms with a complicated medical history. The abdominal pain is associated with titanium allergy reaction from previously inserted titanium-based surgical clips. This patient is concurrently found to have a retained pigtail catheter in the cecum discovered incidentally through radiology. We discuss the presentation, investigations, and treatment of this unusual case. The case also unfolds rare differential diagnoses to keep in mind when encountering a patient with abdominal pain and associated nonspecific symptoms.

The Safety and Efficacy of Anakinra, an Interleukin-1 Antagonist in Severe Cases of COVID-19: A Systematic Review and Meta-Analysis.

This study aims to assess anakinra's safety and efficacy for treating severe coronavirus disease 2019 (COVID-19). Numerous electronic databases were searched and finally 15 studies with a total of 3,530 patients, 757 in the anakinra arm, 1,685 in the control arm were included. The pooled adjusted odds ratio (OR) for mortality in the treatment arm was 0.34 (95% confidence interval [CI], 0.21 - 0.54, I² = 48%), indicating a significant association between anakinra and mortality. A significant association was found regarding mechanical ventilation requirements in anakinra group compared to the control group OR, 0.68 (95% CI, 0.49 - 0.95, I² = 50%). For the safety of anakinra, we evaluated thromboembolism risk and liver transaminases elevation. Thromboembolism risk was OR, 1.59 (95% CI, 0.65 - 3.91, I² = 0%) and elevation in liver transaminases with OR was 1.35 (95% CI, 0.61 - 3.03, I² = 76%). Both were not statistically significant over the control group. Anakinra is beneficial in lowering mortality in COVID-19 patients. However, these non-significant differences in the safety profile between the anakinra and control groups may have been the result of baseline characteristics of the intervention group, and further studies are essential in evaluating anakinra's safety profile.

Probiotics in Inflammatory Bowel Disease: Are We Back to Square One?

Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the alimentary tract whose incidence has been increasing over the past few years. Even though there is a complex interplay of several factors in the pathogenesis of IBD, a decrease in the diversity of intestinal microbiome is commonly found in patients. Extensive research is directed towards the alteration of this microbiome to improve the symptoms of IBD. Probiotics, prebiotics, antibiotics, and diet are studied in this regard extensively. Among them, probiotics have gained more interest as some of the studies showed them to be effective in decreasing gut inflammation in vitro and in vivo. Although there is no cure for IBD as of today, the available medications do decrease gut inflammation and help prolong remission and decrease relapse rates. But their side effects preclude their long-term use. Probiotics may be a ray of hope among IBD patients as they are apparently safe. This article reviews each of the available literature from the past 10 years to see if there is any certain role of probiotics in induction, maintenance of remission, prevention of relapse, and improvement in the quality of life in IBD patients.

Review of Prominent Cytokines as Superior Therapeutic Targets for Moderate-to-Severe Atopic Dermatitis.

Cytokines predominate the inflammatory pathways in diseases like rhinitis, asthma, and atopic dermatitis. Corticosteroids and immunosuppressants are presently the mainstays of treatment for patients with moderate-to-severe disease, but often accompany a poor side effect profile. In this review, we attempt to consolidate current data on various interleukins (IL) that participate in the pathogenesis of atopic dermatitis (AD) to further improve therapeutic strategies. For now, dupilumab is the most accepted biologic to be registered for treatment for moderate-to-severe disease. Recently, IL-37, IL-13, IL-26, IL-17 & IL-31/33 axis as well as proteins like thymic stromal lymphopoietin (TSLP) show promising results as future therapeutic targets because of their important role in the pathogenesis of AD. However, further studies are required to clarify the safety and efficacy of these interventions compared to current treatment modalities but it is worthwhile to pursue research into biologics as a more successful treatment option for moderate-to-severe AD.

Overview of Risk Factors and Prevention of Capsular Contracture Following Implant-Based Breast Reconstruction and Cosmetic Surgery: A Systematic Review.

Capsular contracture is one of the most common complications of implant-based breast reconstruction or augmentation surgery. Despite advanced molecular biology, the exact mechanism of this complication is not fully understood. PubMed was searched for studies, published from 2015 to 2020, focused on potential risk factors and preventions of capsular contracture (CC) in patients who underwent implant-based breast surgery. A total of 533 articles were identified from PubMed, and 13 articles were selected ultimately for our review after eligibility screening and quality appraisal. Common risk factors of CC include biofilm, surgical site infections (SSI), history of prior CC or fibrosis, history of radiation therapy, and implant characteristics. Interventions that decrease the rate of CC include antibiotic prophylaxis or irrigation, acellular dermal matrix (ADM), leukotriene (LTE) inhibitors, surgical techniques, and others. Multiple risk factors are proposed to be a component of the pathophysiology of CC. However, there is inconsistent evidence supporting these risk factors, and the current data was based on broad heterogeneous studies. While efforts are being undertaken to solve this complication with improved technologies and surgical practices, CC remains to be unsolved. Our objective was to provide a summary of the current data of contributing risk factors as well as preventative and treatment measures for CC.

Massive Leiomyomata and Severe Endometriosis Resulting in a Frozen Pelvis in an Asymptomatic Patient.

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.

A Rare Case of Massive Ovarian Mucinous Cystadenoma With Postmenopausal Bleeding.

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.
