Chordee without hypospadias is a rare congenital penile curvature condition without hypospadias. There is no agreement on its etiology or optimal surgical management. The author proposes a technique that involves mobilizing the hypoplastic urethra and corpus spongiosum into the glans and proximal urethra to correct the curvature while preserving the urethra. This avoids complications of other techniques like plication, grafting or urethral resection.

NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

INTRODUCTIONINTRODUCTION
Bhat et al J . PAEDIATRIC UROLOGY Feb 2008
3. DEVELOPMENT OF URETHRADEVELOPMENT OF URETHRA
•At 9 weeks the genital swellings (also called the labio-scrotal folds)
enlarge and rotate posteriorly. As they meet, they begin to fuse from
posterior to anterior.
• As the genital tubercle becomes longer, two sets of tissue folds develop
on its ventral surface on either side of a developing trough, the urethral
groove. The more medial endodermal folds will fuse in the ventral midline
to form the male urethra. The more lateral ectodermal folds will fuse over
the developing urethra to form the penile shaft skin and the prepuce. As
these two layers fuse from posterior to anterior, they leave behind a skin
line: the median raphe.
•By 13 weeks, the urethra is almost complete. A ring of ectoderm forms
just proximal to the developing glans penis. This skin advances over the
corona glandis and eventually covers the glans entirely as the prepuce or
foreskin.
4. EMBRYOLOGICAL EXPLAINATIONEMBRYOLOGICAL EXPLAINATION
Currently three main theories of penile
curvature are
1. Abnormal development of urethral plate
2. Abnormal fibrotic mesenchymal tissue
at the urethral meatus and penile shaft
3. Differential growth of dorsal and ventral
corporal tissue.

9. CONTROVERSYCONTROVERSY
Young proposed that this entity was due
to congenital short urethra & he
suggested that it should be managed by
transection of hypo-plastic urethra &
reconstruction of urethra
Young HH Genital anomalies hermaphrodite and related adrenal
disease Wilkin & Wilkin 1937
10. CONTROVERSYCONTROVERSY
Devine & Horton in 1973 proposed that
chordee without hypospadias is due to
abnormal development of fascial layers of
penis & majority of these could be treated with
resection of fibrous tissue for chordee
correction, transection of urethra is rarely
required
Devine & Horton; Chordee without
Hypospadias J Urol 1973;110: 264
12. INDICATIONS OF SURGERYINDICATIONS OF SURGERY
• Most of the pediatrics urologists consider
chordee to be significant if it is more than
20-30 degree.
• A dorsal approach is preferred for mild
chordee up to 30 degree & conversely
chordee more than 50 degree in being
managed by ventral approach.
• Bologna R A et al Urology 53:608-10 1999
13. SURGERY AT WHAT AGESURGERY AT WHAT AGE
• Cendron and Melin proposed that it should correct after
puberty. They believed that the curvature would improve
spontaneously with the age and secondly it might disturb
the growth of the penis by altering the tunica of corpora
cavernosa.
• But others advocate that if diagnosed in childhood
correction should be at that time. Type III chordee
without hypospadias with mild to moderate chordee it is
logical to wait but in type II and type I should operated in
same age group as of hypospadias or whenever the
child presents to the hospital.
