Bladder exstrophy is a congenital (present at birth) abnormality of the bladder. It happens when the skin over the lower abdominal wall (bottom part of the tummy) does not form properly, so the bladder is open and exposed on the outside of the abdomen. In epispadias, the urethra does not form properly.

Case Report:Massive Ovarian Cyst in a Adolescent GirlTana Kiak
For benign tumours adhesion prevention strategies should be used. Surgical intervention should as much as possible be directed towards preservation of ovarian tissue. There is scarcity of published literature on this subject.
We need bigger studies to address the issue of how much fertility preservation is safely possible.Irrespective of indication for surgery, it is always preferable to attempt conservative, fertility sparing surgery in adolescents.
This slide explains about Germ cell tumor ovary (GCT Ovary). It explains how a various stages developmental anomaly could give rise to various types of GCT.
Borderline ovarian malignancy, also known as borderline ovarian tumor or ovarian tumors of low malignant potential (LMP), is a distinct category of ovarian tumors that fall between benign and malignant tumors in terms of their behavior and potential for spreading.
Characteristics and Diagnosis:
Histological Features: Borderline ovarian tumors have certain cellular abnormalities that suggest malignancy but lack the invasive qualities seen in fully malignant tumors.
Age Group: They often occur in women of childbearing age, and their incidence tends to be highest in women in their 30s and 40s.
Clinical Presentation: Borderline ovarian tumors may be asymptomatic or present with nonspecific symptoms like abdominal pain, bloating, or changes in urinary habits.
Imaging and Biopsy: Diagnosis typically involves imaging studies, such as ultrasound, and a biopsy or surgical removal of the tumor for a pathological examination to confirm its borderline nature.
Treatment and Prognosis:
Surgical Approach: The primary treatment for borderline ovarian tumors is usually surgery, which involves removing the affected ovary or ovaries. The goal is to perform a comprehensive surgical staging to assess the extent of disease without removing both ovaries unless necessary.
Chemotherapy: Unlike malignant ovarian tumors, borderline tumors are less likely to spread beyond the ovaries. In cases where there is evidence of disease spread or in certain high-risk situations, chemotherapy may be considered.
Prognosis: The overall prognosis for women with borderline ovarian tumors is generally favorable. The majority of patients have an excellent long-term survival rate, especially if the tumor is confined to the ovaries at the time of diagnosis.
Follow-Up and Recurrence:
Regular Monitoring: Given the potential for recurrence, patients with borderline ovarian tumors often undergo regular follow-up examinations, including imaging studies and blood tests (such as CA-125), to monitor for any signs of disease recurrence.
Reproductive Considerations:
Fertility-Sparing Options: For women who wish to preserve fertility, there may be options for fertility-sparing surgery in carefully selected cases where the tumor is unilateral, well-staged, and the patient desires future childbearing.
Conclusion:
Borderline ovarian malignancy represents a unique category in ovarian tumors, requiring a multidisciplinary approach involving gynecologic oncologists, pathologists, and other healthcare professionals. While generally associated with a favorable prognosis, individual cases can vary, and personalized treatment plans are essential for optimal outcomes. Regular follow-up and clear communication between patients and healthcare providers play a crucial role in managing and monitoring borderline ovarian tumors.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:

Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. Definition
Wilm’s Tumor is also known as Nephroblastoma. It is
a highly malignant embryonal neoplasm.
It may involve one or both kidney.
3. INCIDENCE AND ETIOLOGY
Usually the tumor is unilateral, but in 5% cases it
may be bilateral.
The tumor involves left kidney more than right
kidney.
It affects children between 3-5 year of age.
CONT………….
4. CONT……………..
The disease occur in about 1 out of 2-2.5 lakh
children.
The exact cause of tumor is unknown, but it has
been identified that tumor suppressor gene acts to
promote normal kidney development. This gene
may be absent or missing in wilm’s tumor.
5.
6. PATHOPHYSIOLOGY
Mostly wilm’s tumor is unilateral but it can be bilateral in
5% of cases
Nephroblastoma are generally large and rapidly growing.
Tumor generally start growing in renal parenchyma or at the
tip of kidney.
cont…….
7. Cont………….
It causes suppression of normal tissue remaining
Majority of tumors present a as single encapsulated mass, that
separates the normal kidney and tumor.
Although the tumor is encapsulated but the membrane may be very
thin and get easily torn
Rupture of tumor put patient at the risk of hemmorhage and
dissemination of tumor
8. CLINICAL FEATURES
Presence of abdominal
mass.
Pain ,if tumor is enlarging
Anorexia
Hematuria
Nausea and vomiting
Urinary tract infection
9. STAGES OF WILM’S TUMOR
STAGE I (43% CASES ) - Tumor limited to kidney and
completely resectable.
STAGE II (23% CASES) - Tumor extend beyond kidney , into
nearby fatty tissue, but it is resectable.
STAGE III (23% CASES) – Non hematogenous spread in
abdomen, like spread to lymph nodes in abdomen or pelvis,
but this stage tumor is not completely resectable.
CONT……………….
10. CONT…………………
STAGE IV (10% CASES) - Hematogenous metastatis
to lungs and liver.
STAGE V (5% CASES)- Bilateral renal involvement.
12. DIAGNOSTIC EVALUATION
History- The child may have positive family history.
Physical examination reveals presence of abdominal mass.
Urinanalysis reveals presence of blood in urine.
Abdominal x-ray
13. Cont………….
Ultrasound
Chest X- ray to detect metastasis to lungs.
Increased Blood urea nitrogen, creatinine values.
14. MANAGEMENT
The management of children with wilm’s tumor include
:-
Radiation therapy
Chemothrapy
Surgical management
15. Radiation Therapy
Wilm’s tumor may be bilateral or large in size ,
may be inoperable, for such cases radiation
therapy may be used to reduce the size of
tumor, so that surgery can be performed.
16. CHEMOTHERAPY
The objective of chemotherapy is to treat any
metastatic lesions that may exist and destroy
any cells in blood stream, before they get
implanted.
The drugs used for chemotherapy are
Actinomycin D, Doxorubicin and Vincristine.
17. SURGICAL MANAGEMENT
Partial or complete nephrectomy is done for
unilateral and for bilateral partial nephrectomy is
done.
After surgical management, chemotherapy and
radiation therapy is given if indicated.
18. TREATMENT
Treatment for wilm’s tumor is based mainly on the
stages of the cancer:-
STAGE I- These tumor are still only in the kidney.
Standard treatment starts with surgery to remove the
part of kidney containing tumor. These children needs
to be watched closely because the chances of
recurrence are higher.The chemotherapy is given for
18 weeks.
19. cont…………..
STAGE III- Treatment is usually surgery followed by
radiation therapy to the abdomen over several days .
This is followed by chemotherapy for about 6
months.
STAGE IV- These tumors are already spread to distant
parts of the body at the time of diagnosis, so
standard treatment id surgery followed by radiation
and chemotherapy.
20. Cont…………
STAGE V- In this stage usually tumor is bilaterally
present, standard treatment involves surgery,
radiation and chemotherapy repeatedly until normal
kidney tissue left behind. In case if not enough
kidney tissue is left after surgery that child may need
to place on dialysis. If there is no evidence of any
cancer after year or two, a donor kidney transplant
may be done.
21. NURSING MANAGEMENT
PREOPERATIVE CARE
Prepare the parents and child for surgery.
Expalin parents not to palpate the abdomen of the
child.
Explain child about post operative care , if he or she is
old enough.
Caution should be taken while turning and handling
the child.
22. POST OPERATIVE CARE
Monitor vitals signs.
Monitor renal functioning by monitoring
weight, intake output and KFT values.
Obsesrve for the signs of functioning.
Use aseptic techniques while doing dressing
Explain parents about follow up and
continuing treatment at the time of discharge.
23. Current Research
Research on diagnostic procedures and treatment
for Wilms tumor is ongoing. The following advances
may still be under investigation in clinical trials and
may not be approved or available at this time.
Always discuss all diagnostic and treatment options
with your child’s doctor.
24. New tumor markers. A tumor marker, also called a serum
marker or biomarker, is a substance found in a person's
urine, or body tissue. Doctors in the United Kingdom recently
discovered that children with Wilms tumor who have a
recurrence all have active genes on one area of a specific
chromosome (the 1q area). Children can be tested to see if
their 1q genes are active, which can help doctors plan
treatment. Once the specific genes are identified, it is
that new tests may be developed to predict which children
likely to have a recurrence.
25. Genetics. A new Wilms tumor gene (WTX) has been
identified on the X chromosome and plays a role in
normal kidney development. This gene is not active in
approximately one-third of children with Wilms tumor.
Studies on the importance of this gene are ongoing.
New therapy combinations. Researchers are looking at
whether patients with a favorable histology Wilms tumor
who have metastases in the lungs need radiation
to the lungs if the lung tumors go away after six weeks
chemotherapy.
