Precancerous colonic polyp are one of the most common lesions reported in intestinal biopsy. Diagnosis becomes more important as the early diagnosis immensely helps in patients management.
Testicular tumors are rare.
1 – 2 % of all malignant tumors.
Most common malignancy in men in the 15 to 35 year age group.

New Drug Discovery and Development .....NEHA GUPTA
The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
2. Colorectal carcinoma(CRC) , one of the most
common cancer worldwide.
Virtually all CRCs originate from a benign polyp
, which makes this cancer potentially
preventable by appropriate screening
colonoscopy programs in patients at increased
risk.
3. The nature of precursor polyp is an essential
classifier of CRC because each tumor is
thought to develop from an unique benign polyp
with its own set of morphologic and molecular
characteristics.
4. The two most common polyps identified as
precursors of CRCs-
Adenomatous polyps and ,
Serrated polyps.
9. Grossly, these polyps grossly appear
rounded, smooth, and unilobular with
an erythematous cap of eroded tissue.
Their cut surface reveals multiple
dilated, mucin-filled crypts, leading to
the term mucus retention polyp. These
polyp share many features with
inflammatory polyp

2. Conventional Adenomas
3. Adenomatous Polyposis Syndrome
4. Adenomas and adenoma – like DALMS in
Inflammatory Bowel Disease
13. Most common type of polyps in colon.
May progress to malignancy.
May grow to large sizes, show abnormal
proliferation and maturation (right side), and
may be sessile.
14. Decrease in the rate of cell death, leading to,
Prolonged cell life
Increase in the no. of epithelial cells
Serrated phenotypic growth pattern
15. Higher susceptibility to DNA methylation
(Unknown reasons)
Transcriptional silencing of promoters of tumor
suppressor genes (MLH1, BRAF, MGMT)
Progression to dysplastic serrated polyps and
ultimately adenocarcinomas
30. Sessile serrated polyps with dysplasia
Serrated adenomas (traditional polyp)
Conventional adenomas with serrated
architecture
31. As a result of dysplastic change within a
sessile serrated polyp.
Resembles a conventional adenoma,
composed of elongated cigar shaped
hyperchromatic nuclei with stratification and
with architectural serration.

lesion into either “nondysplastic” or “dysplastic”
serrated polyp category.

Risk increases with age, at age >50y, 12%
have adenomas, of which 25% are
considered high risk lesion.
55. 1) Non complex
crypts
2) Psuedostratified or
partially stratified
nuclei reach only
the lower half of
cytoplasm
3) Minimal nuclear
pleomorphism/loss
of polarity
4) Brisk mitosis but
minimal atypical
mitosis
5) Arranged more in
parallel
configuration
56. Marked degree of
nuclear
hyperchromaticity,
pseudostratification,
and loss of polarity
from the base to the
surface of the
mucosa.
Intraluminal
cribriforming of the
glands is seen
without a definite
breach of the
basement membrane.
57. More complex intraluminal cribriforming and large gland formation with the
appearance of expanding-type infiltration into the lamina propria without
desmoplasia. In intramucosal carcinoma, the nuclei become more rounded,
rather than cigar shaped, and often contain an open chromatin pattern rather
than a coarse chromatin pattern.
61. The misplaced crypts
are slightly separated
from one another and
marked congestion and
hemosiderin deposition
are seen around the
edges of the misplaced
epithelium.
62. Smooth-edged pool of mucin,
lined by low-grade dysplastic
epithelium on the periphery,
The pool of mucin does not
contain floating atypical cells
or glands
63. Lack of lamina propria
surrounding the invasive
glands; no evidence of
hemorrhage or hemosiderin
deposition is seen.
Irregular and jagged in
contour and infiltrate in a
nonlobular fashion

69. clinically important to make a distinction because sporadic
adenomas are generally treated by polypectomy and
continued surveillance, whereas (adenoma-like) polypoid
dysplastic lesions associated with an underlying IBD have
generally been regarded as an indication for colectomy in
medically fit patients
70.
71. 1) Mutations in DNA mismatch repair genes,
leading to a DNA microsatellite instability (MSI)
phenotype (15-20% cases)
2) Mutations in APC and other genes that
activate Wnt pathway, characterized by
chromosomal instability (CIN) phenotype (75-
85%)
3) Global genome hypermethylation, resulting in
switch off of tumor suppressor genes, indicated
as CpG island methylator phenotype (CIMP).
