Abstract:
Acute generalized exanthemous pustulosis (AGEP) is a rare skin reaction most commonly due to an adverse drug reaction. The rash is characterized by the sudden onset of diffuse pustules on a maculopapular rash. We present a case of a 62-year-old female treated with cephalexin for streptococcal pharyngitis who was admitted with the characteristic rash over her chest, abdomen, arms, and legs that started four days after starting the antibiotic. The diagnosis was further confirmed with a punch biopsy of the affected skin. The rash quickly resolved after discontinuing cephalexin. The patient's course was complicated by findings of a left sternoclavicular joint abscess requiring surgical debridement and resection along with an extended course of intravenous antibiotics. It was felt the abscess was caused by hematogenous spread from the patient's original streptococcal infection as opposed to being directly due to the AGEP, which further added to the complexity of the patient's case.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:30Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Etiology
Three primary contributing factors have been identified.
01:17Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
