Necrosis01:16

Necrosis

3.7K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

813
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes: Symptoms, Diagnosis, and Complications

483
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Skin Diseases and Disorders

2.8K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Acute Pancreatitis II: Clinical Manifestations and Management

71
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Area of Science:

  • Emergency Medicine
  • Infectious Diseases
  • Endocrinology

Background:

  • Diabetes affects over 28 million Americans, leading to millions of emergency department visits annually.
  • Diabetic ketoacidosis (DKA) is a severe complication characterized by hyperglycemia, metabolic acidosis, and ketonemia.
  • Necrotizing soft tissue infection (NSTI) is a life- and limb-threatening condition that can precipitate DKA.

Purpose of the Study:

  • To present a case of DKA precipitated by NSTI.
  • To outline the diagnostic and management strategies for both DKA and NSTI.
  • To enhance emergency medicine residents' ability to manage complex diabetic emergencies.

Main Methods:

  • An oral board-style case simulation was used with emergency medicine residents.
  • Participants were assessed on history taking, physical examination, diagnosis, treatment, and communication skills.
  • Performance was scored using ACGME core competencies.

Main Results:

  • Residents demonstrated recognition of DKA but varied in confidence with potassium and insulin dosing.
  • PGY2 residents scored higher and missed fewer critical actions than PGY1 residents.
  • The case was rated as increasing medical knowledge by participants.

Conclusions:

  • Effective management of DKA and NSTI requires prompt recognition and coordinated treatment.
  • Identifying precipitating factors for DKA, such as infection, is crucial.
  • This case simulation effectively assessed and potentially improved resident preparedness for managing severe diabetic complications.
