Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Clinical Trials

10.9K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Clinical Trials: Overview

5.0K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Toxidromes: Clinical Features

1
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

Changes in Skin Color: Clinical Perspectives

3.8K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

COPD: 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...

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Chiari malformations (CMs) are structural defects at the craniovertebral junction where the cerebellum or brainstem protrudes into the spinal canal.
  • This herniation can compress neural structures and obstruct cerebrospinal fluid (CSF) flow, leading to diverse neurological symptoms.
  • Understanding CM variations is crucial for accurate diagnosis and effective management of associated neurological disorders.

Purpose of the Study:

  • To update and consolidate current knowledge on the anatomical variations of Chiari malformations.
  • To provide a comprehensive resource for healthcare professionals involved in CM diagnosis and treatment.

Main Methods:

  • A comprehensive literature search was conducted across major scientific databases including PubMed, MEDLINE, SciELO, ScopeMed, and Wiley Online Library.
  • Original research papers were selected, and references from these articles were reviewed to identify relevant studies.
  • Extensive net surfing using various terms related to Chiari malformations was performed to gather additional information.

Main Results:

  • The review synthesizes information on the diverse anatomical presentations of Chiari malformations.
  • It highlights the impact of CMs on neurological function, including sensory loss, ataxia, weakness, and nystagmus.
  • The study underscores the importance of detailed anatomical knowledge for clinical practice.

Conclusions:

  • A thorough understanding of Chiari malformation variations is essential for neurologists, neurosurgeons, and radiologists.
  • Accurate diagnosis and management of CMs can be improved through consolidated knowledge of its anatomical spectrum.
  • This review aims to reduce mortality and morbidity associated with Chiari malformations.
