Introduction:
Chronic rhinosinusitis (CRS) is an inflammation of the nasal mucosa and paranasal sinuses for more than 3 months that affects 5 to 12% of the quality of life. Antibiotics are the first line of management for CRS. Increased antibiotic resistance causes ineffective treatment of CRS. This study aims to determine the bacterial pattern that causes CRS before and during the COVID-19 pandemic. Culture sensitivity tests in rhinosinusitis patients were conducted to see changes in the bacterial resistance patterns to antibiotics before and during the COVID-19 pandemic and to determine the appropriate use of antibiotics and prevent an increase in antibiotic resistance in the ENT-HNS outward department of RSUP Dr. M. Djamil Padang.
Materials And Methods:
The type of research was a retrospective study with a total sample of 174 CRS patients who had undergone culture and sensitivity tests. The study population was all CRS patients who were treated at the ENT-HNS outward department at RSUP DR. M. Djamil Padang from 2016 to 2021, underwent surgery and received antibiotic treatment at secondary health services. Antibiotic sensitivity cultures are required for surgery and to determine antibiotics use after surgery. This research was conducted from February to May at the Tertiary Hospital of Dr. M. Djamil Padang. The data collection technique used a total sampling technique. The sample in this study was taken from the medical records of patients at the ENT-HNS outward department of RSUP Dr. M. Djamil Hospital, Padang.
Results:
The results showed that the prevalence of CRS with polyps before COVID-19 was 63.8% of cases. After COVID- 19, the prevalence of CRS with polyps was found to be 60% of cases. Before the COVID-19 pandemic, CRS was most common among those aged ≥ 41 to 50 years (27%) and the most common bacteria causing CRS with or without polyps was Staphylococcus aureus (39%; 44%). The bacteria causing CRS with or without polyps after COVID-19 were mostly Staphylococcus epidermidis (50% of cases). Before the COVID-19 pandemic, amoxicillin-clavulanic acid had a high resistance of 75 to 100%, however, after COVID-19 there was a change in antibiotic resistance patterns and an increase in ciprofloxacin resistance of 56 to 100% was obtained.
Conclusion:
This change in antibiotic resistance pattern needs attention to prevent drug resistance, especially after COVID-19.

01:20Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

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:
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,...
