Insulinomas are rare functional pancreatic neuroendocrine tumors that typically manifest with classic hypoglycemic symptoms, such as diaphoresis, palpitations, and tremors. Although infrequent, neuroglycopenic symptoms associated with insulinomas have been reported, often leading to delayed diagnoses. Here, we present the case of a 31-year-old male with pancreatic insulinoma who experienced recurrent episodes of seizures and confusion preceded by diaphoresis, tremors, and palpitations.

Although Leigh syndrome (LS) is a neurodegenerative disorder of infancy, adult-onset LS has also been rarely reported. We report a case of late-onset LS in a 42-year-old female who presented with protracted gastrointestinal manifestations, chronic headaches, ataxia, and loss of consciousness. Brain magnetic resonance imaging (MRI) revealed hyperintensities in the bilateral basal ganglia and brain stem.

Antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (GN) is an immune-mediated kidney disease characterized by the inflammation of small blood vessels in the kidney, leading to renal impairment and potentially irreversible damage. Concerns have been raised over the reports of myeloperoxidase/perinuclear (MPO/p) ANCA GN following the coronavirus disease 2019 (COVID-19) vaccination. Our study provides a comprehensive insight into perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) GN after COVID-19 vaccination.

Dengue fever, the most prevalent arbovirus disease, has a broad spectrum of clinical manifestations, ranging from asymptomatic to dengue hemorrhagic fever and dengue shock syndrome. Dengue fever has the potential to involve the nervous system. Acute transverse myelitis is a life-threatening complication of dengue fever, though rarely reported.

Sarcoidosis, a systemic granulomatous disorder, typically involves the lungs, skin, and lymph nodes. Neurological manifestations are diverse and may include longitudinally extensive transverse myelitis (LETM), an uncommon inflammatory disorder of the spinal cord. We present a case of a 62-year-old female with LETM as the initial manifestation of sarcoidosis.

Objectives: As a result of recent biomedical advancements, organ donation continues to save and enhance countless lives globally.Yet,the gap between the organ supply and demand persists, leading to approximately 17 people dying each day waiting for an organ transplant and another person being added to the transplant waiting list every 9 minutes. This gap persists, in part, because of ethical and practical concerns arising from ambiguities surrounding death determination before donation and the dead donor rule.

Takotsubo cardiomyopathy (TCM) is a life-threatening transient left ventricular dysfunction triggered by either physical or emotional stressors. Concerns have been raised on reports of TCM after the coronavirus disease 2019 (COVID-19) vaccine. Our study provides comprehensive detail on COVID-19 vaccine-induced TCM.

Obstructive jaundice is a joint clinical presentation with many etiologies, including pancreatic cancer and autoimmune pancreatitis (AIP). Differentiating between these two conditions is pivotal due to the divergent management approaches and prognoses. In this case report, we present a case of a 49-year-old female patient who presented with weight loss, intermittent chronic abdominal pain, and jaundice.

Cardiac angiosarcoma is a rare and aggressive malignant tumor arising from the endothelial cells of the heart. It accounts for only a small fraction of all cardiac neoplasms and has a poor prognosis. We present a challenging case of a 20-year-old student who presented exertional dyspnea, palpitation, and occasional chest discomfort.

Although the efficacy and safety of the coronavirus disease 2019 (COVID-19) vaccine have been established, side effects and adverse events related to the COVID-19 vaccine are still coming out. COVID-19 vaccine also has the potential to cause acute and long-term cardiovascular effects, which include myocarditis, pericarditis, myopericarditis, myocardial infarction, pulmonary embolism, thrombotic thrombocytopenia, and pulmonary hemorrhage. Although uncommon, takotsubo cardiomyopathy (TCM) has also been reported following COVID-19 vaccination.

Atrial myxoma is the most frequent primary cardiac tumor; however, it is a rare, substantial cause of cardiogenic emboli causing a stroke, especially in young adults. A cardiac myxoma has no specific clinical presentation, ranging from constitutional symptoms to non-cardiac symptoms and emboli, which leads to a diagnostic challenge in the clinical process. We report a case of a left atrial myxoma in an adult female who presented with sudden onset of right-sided weakness, headache, and numbness.

Dysautonomia is a common and severe complication of Guillain-Barré syndrome (GBS), which may manifest as cardiac arrhythmias, labile blood pressure, diaphoresis, and changes in gastrointestinal motility. Takotsubo cardiomyopathy (TCM) is a life-threatening manifestation of dysautonomia in patients with GBS, which is not widely underlined in the literature. The association between GBS and TCM has been well-documented in previous studies; however, there are few reported cases with GBS who developed TCM following their diagnosis with GBS.

Acute pancreatitis is an inflammatory condition with varying local and systemic complications and variable severity. Although rare, cardiovascular complications induced by acute pancreatitis are rarely described in the literature. Epigastric pain with acute pancreatitis often simulates electrocardiographic changes in the absence of coronary artery abnormalities, resulting in a diagnostic dilemma for optimal treatment and management.

Thrombotic thrombocytopenic purpura (TTP) is a rare autoimmune and devastating blood disorder that results in micro-clots throughout the body, leading to tissue damage and organ dysfunction resulting in widespread microangiopathic hemolytic anemia, thrombocytopenia, fever, and neurological symptoms. TTP patients commonly manifest renal and neurological symptoms; however, cardiovascular involvement is not widely reported in the literature. We report a case of non-ST-segment elevation myocardial infarction (NSTEMI) as an initial manifestation of TTP.

Mass vaccination against coronavirus disease 2019 (COVID-19) has been safe and effective. The ongoing emergence of vaccine-induced complications has challenged the public trust in vaccination programs and, though uncommon, can lead to significant morbidity and mortality. Vaccine-induced immune thrombocytopenia and thrombosis (VITT) is a rare and fatal complication of the COVID-19 vaccine.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is an immune-mediated disorder of small and medium-sized vessels, characterized by the production of autoantibodies that target the neutrophilic antigens leading to mononuclear cell infiltration and destruction of blood vessels in lungs, skin, and kidneys. Although rare, the coronavirus disease 2019 (COVID-19) vaccine may trigger autoimmune vasculitis. We report a rare case of ANCA-associated renal vasculitis following COVID-19 vaccination in a 59-year-old male who presented with flu-like symptoms and deranged renal function tests.

Executive functioning and its related components have been found to promote well-being. However, there is a limited understanding of the underlying mechanism. Drawing from the job demands-resources and PERMA models, the present study examined the hypothetical mediating role of work engagement in the relationship between executive functioning deficit and well-being among 314 working adults in Malaysia.

A dermoid cyst, also called a mature teratoma, is a benign tumor of the ovary derived from pluripotent germ cells. It is often asymptomatic; however, it can be expressed by several complications, including infection, adnexal torsion, and rupture. Rarely ovarian dermoid cysts can also transform into malignant degeneration.

In South Asia, tick transmits Kyasanur Forest Disease Virus (KFDV), a flavivirus that causes severe hemorrhagic fever with neurological manifestations such as mental disturbances, severe headache, tremors, and vision deficits in infected human beings with a fatality rate of 3-10%. The disease was first reported in March 1957 from Kyasanur forest of Karnataka (India) from sick and dying monkeys. Since then, between 400 and 500 humans cases per year have been recorded; monkeys and small mammals are common hosts of this virus.
