まとめ
再発性呼吸器パピロマトーシス (RRP) 患者からの口洗いでは,ヒトパピロマウイルス (HPV) のDNAが検出され,液体生検として有望であった. これらのRRP症例では, palatineとpharyngeal tonsilsはHPVを保持しませんでした.
科学分野:
- 耳鼻喉科
- ウイルス学
- 腫瘍学
背景:
- 再発性呼吸器パピロマトーシス (RRP) は主に低リスクヒトパピロマウイルス (HPV) 型に関連しています.
- 口水は,口腔がんの検出に類似した,潜在的に非侵襲的な診断ツール (液体生検) として登場しました.
- 口水中のHPVの存在を調査することは,RRP管理のための新しいアプローチを提供することができます.
研究 の 目的:
- 再発性呼吸器パピロマトーシス (RRP) の患者のHPVDNAを検出するための液体生検として口腔洗浄の有用性を評価する.
- RRP患者において,口腔と喉の桃体がHPVの貯蔵体として機能するかどうかを判断する.
主な方法:
- 7人のRRP患者の口水,口腔桃体,喉桃体サンプルを採取した.
- HPV DNA検出のためにポリメラーゼ連鎖反応 (PCR) を利用した.
- 標本に含まれる特定のHPV型を特定するために,HPV遺伝子型を決定した.
主要な成果:
- 7つの口腔洗浄サンプルのうち5つでHPVDNAが検出されました.
- palatineまたはpharyngeal tonsil swabのいずれにも HPV DNAは検出されなかった.
- 5件のHPV陽性経口洗浄のうち4件のHPV6がRRP組織で確認された.
結論:
- 口水は,RRP患者のHPVDNAを検出するための有効な情報源であり,液体生検として使用することを支持しています.
- 研究されたRRP患者のコホートでは, palatineとpharyngeal tonsilsがHPV貯蔵体であることが判明しなかった.
- この発見は,RRP管理における非侵襲的なHPVモニタリングの可能性を強調しています.

Sputum Studies I: Gram Stain, cytology, and Acid-fast smear and culture
Sputum studies are a critical part of diagnosing and treating numerous respiratory conditions. These studies involve obtaining sputum samples for analysis to identify pathogenic organisms and assess the presence of abnormal cells indicative of malignant conditions. This lesson will delve into three fundamental sputum studies: Gram Stain, Cytology, and Acid-fast Smear and Culture.
Gram Stain

Sputum Studies II: Culture and Sensitivity
Description
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,...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
