Q --Define spina bifida and its sign, symptoms, complication.
Spina bifida is a neural tube defect (NTD) that occurs when the spinal column does not close completely during early fetal development, usually within the first month of pregnancy. This condition can lead to physical and neurological complications, depending on the type and severity.
Spina bifida is a congenital defect in which the vertebrae fail to close around the spinal cord, leading to an opening in the spine. It can...
Q -- Describe the etiopathogenesis, clinical features, diagnosis and management of meningitis.
Here's a comprehensive overview of meningitis, covering etiopathogenesis, clinical features, diagnosis, and management:
Meningitis refers to inflammation of the meninges, the protective membranes covering the brain and spinal cord. It may be caused by infectious or non-infectious agents.
Infectious causes:
Bacterial (most serious form):
Neonates: Group
Q --- Describe the mechanism of heart failure and describe the management of heart failure.
Heart failure (HF) is a clinical syndrome that occurs when the heart is unable to pump blood sufficiently to meet the metabolic needs of the body, or can only do so with elevated filling pressures. It can result from structural or functional cardiac disorders.
Heart failure can be classified into:
Heart Failure with Reduced Ejection Fraction
Q -- Describe the mechanism of heart failure and describe the management
Heart failure (HF) is a clinical syndrome in which the heart is unable to pump sufficient blood to meet the metabolic needs of the body. It results from structural or functional cardiac disorders that impair the ability of the ventricles to fill with or eject blood.
Heart failure can be broadly classified into:
Q --- Etiology and clinical features of infective endocarditis
Infective endocarditis is an infection of the endocardial surface of the heart, usually involving the heart valves. It is caused by microorganisms, primarily bacteria and occasionally fungi.
Bacteria:
Staphylococcus aureus (most common overall, especially in acute IE and IV drug users)
Viridans group streptococci (common in subacute IE, especially after dental
Q -- Define pain gate theory and its uses.
Pain Gate Theory (also known as the Gate Control Theory of Pain) is a scientific theory that explains how pain is perceived and modulated by the nervous system. It was first proposed by Ronald Melzack and Patrick Wall in 1965.
Pain Gate Theory suggests that pain signals from the body do not travel directly to the brain. Instead, they pass through a "gate" mechanism in the spinal cord, specifically in the dorsal horn. This gate can either allow...
Q -- Define UVR. Explain the procedure and indication of UVR.
UVR (Ultraviolet Radiation) refers to a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays, typically ranging from 100 to 400 nanometers (nm). It is divided into three main categories:
UVA (315–400 nm) – Least harmful, penetrates deeper into the skin.
UVB (280–315 nm) – Causes sunburn, has more energy, and is more harmful to the skin.
UVC (100–280
Q -- Write indetail about technigue of applications of laser and its indications and contraindications.
Here's a detailed explanation of the technique, applications, indications, and contraindications of laser use in medicine and surgery.
LASER stands for:
Light Amplification by Stimulated Emission of Radiation
Lasers emit coherent, monochromatic, and collimated light, which can be precisely focused on...
Q --- Physical properties of laser.
The physical properties of a laser (Light Amplification by Stimulated Emission of Radiation) describe the unique characteristics of the light it emits. Here are the key physical properties:
Definition: Laser light consists of a single wavelength (color).
Explanation: Unlike ordinary light (which contains multiple wavelengths), laser light is highly monochromatic, meaning it has a narrow spectral width.
Definition: The
