Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

India Clinical Trials Market: Industry Size and Growth Trends [2030] Analyzed...Kumar Satyam
According to TechSci Research report, "India Clinical Trials Market- By Region, Competition, Forecast & Opportunities, 2030F," the India Clinical Trials Market was valued at USD 2.05 billion in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 8.64% through 2030. The market is driven by a variety of factors, making India an attractive destination for pharmaceutical companies and researchers. India's vast and diverse patient population, cost-effective operational environment, and a large pool of skilled medical professionals contribute significantly to the market's growth. Additionally, increasing government support in streamlining regulations and the growing prevalence of lifestyle diseases further propel the clinical trials market.
Growing Prevalence of Lifestyle Diseases
The rising incidence of lifestyle diseases such as diabetes, cardiovascular diseases, and cancer is a major trend driving the clinical trials market in India. These conditions necessitate the development and testing of new treatment methods, creating a robust demand for clinical trials. The increasing burden of these diseases highlights the need for innovative therapies and underscores the importance of India as a key player in global clinical research.

This insightful piece delves into the potential of these cells to regenerate damaged kidney tissue, offering new hope for patients and reshaping the future of nephrology.
Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

6. However some patients present with excessive overbite.
Such a condition where there is excessive overlapping of the mandibular anteriors by the maxillary
counterparts is called DEEP BITE

common in Caucasian Americans compared to African Americans and Hispanics.

10. Skeletal Deep Bite
They are usually of genetic origin.
It is caused by :
- Upward and forward movement of mandible.
- Downward and forward inclination of maxilla.
- Combination.
Normal Skeletal Relationship.
1. Skeletal relationship
due to upward and
downward rotation
of mandible.
2. Skeletal deep bite due
to downward and
forward rotation
of maxilla
3. Combination of 2 & 3.
12. Dental Deep Bite
It is characterised by the absence of
any skeletal complicating features
seen is skeletal deep bites.
It occurs due to:
- Over-eruption of anteriors.
- Infra-occlusion of molars.
13. Over-eruption of anteriors
- Usually seen in Class II malocclusion.
- Increased overjet causing the lower
incisors to over-erupt until they meet the
palatal mucosa.
Increased curvature of the Curve of Spee
Over-eruption of
mandibular incsiors
due to increased overjet.
14. Infra-occlusion of molars
- Partially erupted molars.
- Lateral tongue posture/thrust preventing molars
from erupting to their normal occlusal level.
- Premature loss of posteriors. Lateral tongue thrust pushing molars
away from normal occlusion level
Partially erupted molar resulting
in deep bite
Premature loss of posterior
causing bite collapse
20. 1. Removable Appliances.
ANTERIOR BITE PLANE is the most
commonly used removable appliance
for the correction of deep bite.
It is a modified Hawley’s appliance
with a flat ledge of acrylic behind the
upper anteriors. When the patient bites,
the mandibular incisors contact the bite
plane thus disoccluding the posteriors
that are free to erupt.
21. ACTIVATOR can be used to treat deep
bites due to infra-occlusion of molars.
It consists of Hawley’s type retainer on the
maxillary arch and lower lingual horse
shoe shaped flange.
It acts by posturing forward a retrognathic
mandible.
BIONATOR which is less bulky and more elastic
than the activator can be used for a similar purpose.
Contd.
22. TWIN BLOCK APPLIANCE appliance
can also be used to correct deep bite.
It consists of an upper and a lower plate
having occlusally inclined bite planes that
induce favorably directed occlusal forces
causing a functional mandibular
displacement.
Contd.
23. 3. Fixed Appliances.
ARCH WIRES WITH REVERSE
CURVE OF SPEE:
Here arch wires are curved
in a direction opposite to that of Curve
of Spee.
When these arch wires are inserted into
the molar tubes and activated it curves
the anterior segment gingivally.
24. HERBST APPLIANCE has revolutionized
the way orthodontists
treat an overbite/deep bite.
It uses a tube and rod mechanism.
When the patient bites or when the teeth
are being occluded it puts pressure on the
lower jaw to help it grow forward and on
the upper jaw to assisting it to grow
backwards.
Thus checking the increased overjet in Class
II malocclusion patients.
Contd.
25. 4. Orthognathic Surgery
ORTHOGNATHIC SURGERY AKA
CORRECTIVE JAW SURGERY is also a
treatment module in cases of severe skeletal
deep bites.
In some patients, orthodontics alone will
not align the teeth and jaws into a harmonious
and aesthetically pleasing position required
to correct various misalignments/malocclusion.
In those instances orthognathic surgery is
indicated to surgically reposition the upper or
lower jaws into a correct anatomical position.
Here the upper or lower jaw is precisely cut and
moved into a new appropriate position and
stabilised with a plating system.
