Abstract:
A 60-year-old man visited our hospital for further examination of an abnormal chest radiograph. Computed tomography (CT) images revealed enlarged mediastinal lymph nodes and multiple pulmonary nodules. Further evaluation by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed and he was diagnosed with sarcoidosis. Six weeks after EBUS-TBNA, he presented to the emergency department with a high-grade fever. CT scan revealed an enlarged mediastinal lymph node. He was diagnosed with mediastinal adenitis and treated successfully with antibiotics. EBUS-TBNA is a highly accurate diagnostic tool, but clinicians should be aware of mediastinal infectious complication that could be asymptomatic for long period of time.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
