The pineal gland is a small endocrine gland located in the center of the brain that produces melatonin. Pineal region tumors originate from cells in and around the pineal gland. These tumors represent 1% of brain tumors in children and adults but account for 3-8% of intracranial tumors in children. Symptoms include headache, nausea, vision changes, and endocrine abnormalities. Diagnosis involves imaging like CT and MRI scans. Treatment options include surgical resection, radiation therapy, chemotherapy, and management of hydrocephalus.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

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

2. Pineal gland
The pineal gland (also called the pineal body,
epiphysis cerebri, epiphysis, conarium or
the "third eye") is a small endocrine gland in the
vertebrate brain. It produces the serotonin
derivative melatonin,Its shape resembles a tiny
pine cone (hence its name), and it is located near
the centre of the brain, between the two
hemispheres, tucked in a groove where the two
rounded thalamic bodies join.
3.
4. Pineal gland Tumor
Pineal region tumors are derived from cells located
in and around the pineal gland (pinocyte & pineal
parenchymal cells)
This cell is a specialized neuron related to retinal
rods and cones.
5. Epidemiology
These tumors represent about 1% of all brain
tumors but account for 3% to 8% of the
intracranial tumors that occur in children.
Most children are aged 10-20 years at
presentation, with the average age at presentation
being 13 years.
Adults typically are older than 30 years at
presentation.
6. Etiology
Tumors can be divided into germ cell and non–
germ cell derivatives.
Most tumors are a result of displaced embryonic
tissue, malignant transformation of pineal
parenchymal cells, or transformation of
surrounding astroglia.
No specific genetic mutations have been
associated with sporadic pineal region tumors
8. Clinical Manifestations
Headache
Nausea
Vomiting caused by aqueductal compression
Obstructive hydrocephalus.
Increased ICP, Seizures, Vision changes (Inability to focus on objects,
double vision, and impairment of eye movements)
Lethargy
Obtundation
In Children endocrine malfunction
Hydrocephalus or concurrent suprasellar- diabetes insipidus
Pseudo precocious puberty
In a large series of patients , 93% of girls older than 12 years
had secondary amenorrhea
33% of patients younger than 15 years had growth arrest.
9. Diagnostic findings
Physical examination & Clinical history
Neurological exam: vision, hearing, balance,
coordination and reflexes
CT Scan
MRI Scan
Angiogram
X-rays of the Head and Skull

10. Treatment
Surgery:
The surgeon drills a small hole called burr hole, into
the skull. A narrow, thin needle is then inserted
through the hole. Tissue is removed using the needle,
which is frequently guided by CT scanning
if possible minimally invasive technique is used
