Fulminant type 1 diabetes mellitus (T1DM) is idiopathic T1DM with the rapid destruction of pancreatic β-cells. We herein report a 48-year-old man who developed fulminant T1DM complicated with a life-threatening electrolyte abnormality and abnormal electrocardiogram findings. He had no remarkable medical history, but one day, he developed general fatigue. His blood glucose level and HbA1c were 806 mg/dL and 6.3%, and his insulin secretion was markedly suppressed. He had ketoacidosis, hyponatremia and hyperkalemia. Furthermore, a life-threatening abnormality was noted on electrocardiogram. After fluid infusion and insulin therapy, the abnormality disappeared. In conclusion, we should bear in mind the possibility of fulminant T1DM in patients complaining of general malaise.

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
