Social Foundations of Self IV: Self in Digital Communication01:30

Social Foundations of Self IV: Self in Digital Communication

210
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Urologic Endoscopic Procedure: Cystoscopic Examination01:28

Urologic Endoscopic Procedure: Cystoscopic Examination

3.3K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Ultrasonography

8.0K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Ultrasound I: Abdominal Ultrasonography

1.7K
Introduction:
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...

Uncertainty in Measurement: Reading Instruments

53.3K
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Area of Science:

  • Urology
  • Medical Imaging

Background:

  • Three dimensional ultrasound (3D US) has emerged as a significant tool in urology over the past decade.
  • While primarily used for research, its clinical applications are expanding due to rapid image acquisition and multiplanar display capabilities.

Observation:

  • 3D US acquires numerous images rapidly, displaying sagittal, transverse, and coronal planes simultaneously.
  • It facilitates Doppler studies and utilizes image subtraction for clear visualization of vascular structures.
  • The coronal plane offers a clear view of the prostate transition zone, enabling precise biopsies.

Findings:

  • 3D US improves early diagnosis of prostate carcinoma by enabling precise guided biopsies.
  • It overcomes limitations of conventional transrectal ultrasound (TRUS) in staging prostate cancer and assessing ejaculatory duct invasion.
  • The technology provides detailed imaging of vascular anastomoses in kidney transplant recipients, aiding in rejection assessment.

Implications:

  • 3D US enhances diagnostic accuracy in urological diseases, particularly prostate cancer.
  • It offers improved staging and monitoring capabilities, potentially leading to better patient outcomes.
  • The technology shows promise in evaluating kidney transplant vascular health and detecting rejection.
