CLINICAL AND LABORATORY FEATURES OF ACUTE VIRAL GASTROENTERITIS IN ADULTS, RESIDENTS OF NOVOSIBIRSK
Summary
Viral gastroenteritis affects 19.6% of adult patients, with noroviruses being the most common cause. Clinical symptoms and lab results showed few differences between viral types, highlighting the need for universal diagnostic tests.
Area of Science:
- Infectious Diseases
- Virology
- Gastroenterology
Background:
- Acute gastroenteritis is a common condition with various etiologies.
- Determining the specific viral cause is crucial for effective management and public health surveillance.
Purpose of the Study:
- To determine the frequency of acute viral gastroenteritis in adult patients in Novosibirsk.
- To identify the clinical and laboratory features associated with different viral gastroenteritis pathogens.
Main Methods:
- Polymerase chain reaction (PCR) was used to detect and differentiate human rotaviruses group A and C (HRVA, HRVC), norovirus genogroup II (HNoV GII), and astroviruses (HAstV).
- A total of 363 adult patients hospitalized with acute gastroenteritis were examined during the winter-spring season.
Main Results:
- Viral etiology was identified in 19.6% of patients.
- Noroviruses were the predominant cause (10.2%), followed by rotaviruses (7.7%) and astroviruses (1.7%).
- Most cases (99.4%) presented as moderate illness, with no significant clinical or laboratory differences between viral types, except for higher lymphocytosis in norovirus infections.
Conclusions:
- The study established the frequency of viral gastroenteritis in adults in Novosibirsk.
- The lack of distinct clinical presentations necessitates the development of universal diagnostic systems for common viral pathogens.

01:20COPD: Pathogenesis and Clinical Features
1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

688
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

341
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
