POEMS Syndrome



POEMS Syndrome [Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes] also known as Crow–Fukase syndrome.

Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome is a rare multisystemic disease that occurs in the setting of a plasma cell dyscrasia. The pathophysiologic link between the constellation of symptoms and the underlying disease is not well understood, but the link may be related to changes in the levels of a cytokine or a growth factor.[Mediscape]

Primary amyloidosis Ppts latest 50 Published articles



Primary amyloidosis: Primary amyloidosis is a disorder in which abnormal proteins build up in tissues and organs. Clumps of the abnormal proteins are called amyloid deposits.

Primary amyloidosis can lead to conditions that include:
    Carpal tunnel syndrome
    Heart muscle damage (cardiomyopathy) leading to congestive heart failure
    Intestinal malabsorption
    Liver enlargement
    Kidney failure
    Nephrotic syndrome
    Neuropathy (nerves that do not work properly)
    Orthostatic hypotension (abnormal drop in blood pressure with standing)

Pediatric Urology- Gynecology



Pediatric Urology- Gynecology
By:Keith Wilkinson, MD FACEP

Anatomy
Shaft
Corpus Cavernosum (two)
* Two large columns on penile dorsum
* Columns separated by septum of fibers
Corpus spongiosum
* Located on ventral side (underside) of penis
* Does not contribute to penile rigidity
* Contains urethra
Tunica albuginea
* Bands together the two columns of corpus cavernosa
Lacunar space (Space of Smith)
* Surrounds tunica albuginea
* Intralacunar smooth muscle found within space

Anatomy
Glans
Innervation-
Sensation-
Pudendal nerve supplies dorsal nerves to penis
Erectile function- Nerves course through corpus cavernosa
Parasympathetic input (excitatory)- “Point”
Nervi erigentes runs adjacent to prostate gland
Sympathetic input (inhibitory)- “Shoot”
Sympathetic nerves supplied by thoracolumbar plexus
Vascular Supply of the Penis
Arterial inflow
Branches of deep internal pudendeal arteries

Hypospadias
* Incomplete development of the anterior urethra
o Anterior- (50 %)- Distal 1/3rd ventral shaft
o Middle- (20 %) percent of cases)- Middle 1/3rd
o Posterior hypospadias (30%)- Proximal 1/3rd
* More common in caucasians (esp Italians, Jews)
* Hypospadias, chordee associated with undescended testes and inguinal hernia (9- 17%)
o Abnormalities of the higher urinary tract are infrequent
* Treatment
o Single stage repair at age 6-18 months

Phimosis
* Previously retractable foreskin no longer retractable or foreskin retraction doesn’t occur by puberty
* Most retract by 1 year with 80% by age 4
* Rare in children
* Circumcision, repeated trauma, infections, poor hygiene, or chemical irritation
* Kids more likely to have obstruction
o Adults present with pain
* Surgery for obstruction of urinary stream, recurrent UTI or bouts of balanoposthitis

Phimosis
* Treatment
o Rare- only required for retention, possible prepuce abscess
o Urinary retention
+ Tub urination
+ Place feeding tube
+ Suprapubic aspiration safe, temporary
o Dorsal slit
+ Dorsal block or collar block
+ Double hemostat crush swollen prepuce
+ Incise between hemostats
+ Close open ends with absorbable suture
* Inability to extend foreskin back over glans
* Less common than phimosis
* Much more common in adults than kids
* More pressing than phimosis
* Often iatrogenic
* Therapy
o Pain management-
+ Topical 2% lidocaine gel or EMLA (eutectic mixture of local anesthetics cream [2.5% prilocaine, 2.5% lidocaine]
+ Systemic analgesia, dorsal penile nerve block, ring block
+ 1-5 cc lidocaine without epi
# 1/2 at 10:00 and 2:00 position at shaft base
# Inject between Buck’s fascia and corpora
o Control of edema-
+ Granular sugar to the surface of the swollen foreskin, cover with a condom or a finger of a rubber glove
+ Cool, compressive 1-in Surgical Cling dressings wrapped distal to proximal
+ Cooled with ice water-filled latex examination gloves
* Therapy
o Direct circumferential manual compression
o Hyaluronidase
+ 1 mL of hyaluronidase (150 U/cc Wydase) injected via TB syringe directly into several sites of the edematous foreskin
+ Breaks down hyaluronic acid in connective tissue, enhances fluid diffusion between tissue planes
+ Almost immediate decreased swelling
o Manual reduction
+ Distal traction of the foreskin using index and third fingers
+ Thumbs push the glans penis back through the paraphimotic ring of the foreskin
o Dorsal slit

Balanitis
Inflammation of the glans
* More common in men than boys
* Causes

Uncircumcised, poor hygiene
Chemical irritants (soap, petroleum jelly)
Drug allergies (tetracycline, sulfonamide)
Morbid obesity
Candidal species
Group A and B streptococci, Staph.,
Trichomonal species
Herpes Simplex
* Recurrent bouts can lead to phimosis

Balanitis
* Testing
o Serum glucose
o Culture of discharge
o Wet mount for Candida
o Syphilis serology test if STD suspected
o Herpes PCR swab
o Gonorrheal, chlamydia in adolescent, suspicion of abuse
* Treatment
o Retract the foreskin daily and soak in warm water to clean penis and foreskin
o Apply Bacitracin (not Neosporin)
o Apply topical clotrimazole for probable candidal balanitis

Balanoposthitis
* Inflammation of the glans and foreskin
* Etiology- uncircumcised, usually preschoolers
o Infection-
+ Grp A Strep (thin, purulent discharge; rapid strep positive), Staph, Candida, rarely gram negatives, syphilis (adolescents)
o Chronic friction, zipper injuries, and contact dermatitis, or a fixed drug eruption (TCN, or clotrimazole)
o Chronic- Balanitis xerotica obliterans
* Treatment-
o Local hygiene (sitz baths, cleaning)
o 0.5% hydrocortisone cream to the affected parts
o Antimicrobial topical ointments
+ Utility is unproved
o Oral antibiotics
+ 5 to 7 days of amoxicillin or cephalexin in recalcitrant cases or with more advanced cellulitis
+ Recurrence raises suspicion of DM, immunocompromise, Balanitis xerotica obliterans

Pearly Papules
* Common- seen in 30%
o Most common in young, uncircumcised African- Americans
* Empty hair follicules on the corona
* Benign- Do not warrant treatment
o Don’t resolve with circumcision
* Can be confused with (genital warts)

Meatal Stenosis
* Circumcised males
* Follows inflammatory reaction around meatus
o Usually diaper rash
* Significant when sprays or dorsally deflects stream
* Obstruction, dysuria, UTI uncommon
o Tub voids, urologic consultation
o Foley catheter, urethral meatotomy
Priapism
* Can occur in any age group
o Peaks at age 5-10 years, 20-50 years
* Causes
o Erectile dysfunction drugs most common causes of adult priapism (0.05-6% of users)
o Sickle cell most common cause in children
+ Causes 2/3rd of all cases
+ Occurs in 27% male children, 89% male adults
+ Highest aged 19-21 years
* Duration of symptoms most important factor affecting outcome
o Up to 92% with priapism for less than 24 hours remained potent
o Only 22% with priapism that lasted longer than 7 days remained potent
* Erection-smooth muscle relaxation and increased arterial flow into the corpora cavernosa
o Engorgement of the corpora cavernosa causes compression of the venous outflow tracts (ie, subtunical venules), resulting in blood trapping within the corpora cavernosa.
o Nitric oxide- major neurotransmitter controlling erection
+ Corpora cavernosa endothelium lining secretes nitric oxide

* Priaprism - failure of detumescence
+ Underregulation of arterial inflow (ie, high flow)
+ Failure of venous outflow (ie, low flow)- more common
# Excessive release of neurotransmitters
# Blockage of draining venules (eg, mechanical interference in sickle cell crisis, leukemia, or excessive use of IV TPN
* Treatment
o Impotence uncommon
o Need for surgical decompression uncommon
o Most low- flow, resolves spontaneously
o Hydration, analgesia
* Sickle cell disease
o Analgesics, hydration
o Exchange transfusion
+ Aim for reduction of Hgb S to 30- 35%
+ Aim for HCT > 30%
o Medical therapy successful up to 37%Alpha, beta agonists
o Oral pseudoephedrine or oral beta-agonists- (terbutaline) little efficacy
* Penile nerve block
o Bupivicaine without epi
* Intercavernosal phenylephrine (Neo-Synephrine)- drug of choice
o Nearly pure alpha agonist
o Intracavernosal injection
o 1 mL:1000 mcg diluted with an additional 9 mL NS
o Inject 0.3-0.5 ml using a 29-gauge needle into the corpora cavernosa
o Compress area of injection
o Wait 10-15 minutes between injections

Penile decompression
* Repeated aspirations or irrigations and sympathomimetic injections over several hours might be necessary
* Resolution of ischemic priapism following sympathomimetic injection with or without irrigation has been shown to occur in 43-81%
* Aspiration- 16- to 18-gauge angiocath into the lateral aspect of the corpus cavernosum
o Unilateral approach usually adequate because of the vascular channels between the 2 corpora cavernosa
o May be difficult because of the sludging of blood within the corpus cavernosum
o Saline irrigation and repeated aspirations may improve flow dynamics
* Surgical decompression
* Phenylephrine irrigation
o 1000 mcg phenylephrine in 100 mL of normal saline (10 mcg/mL)
o Infuse 10-20 mL at a time
o If unable to infuse, inject phenylephrine directly in 200- to 500-mcg aliquots
o Maximum dose of 1500 mcg
o Compression must be applied
o Epinephrine can also be used

Penile Trauma
* Zipper injury
o Local anesthetic
o Cute median bar with wire cutters
* Corporal rupture
o Adolescents, teens, adults
o Palpable, audible snap
o Acute bending of the penis
o Acute pain, immediate detumescence
o Delayed presentation common
o Treatment
+ Exploration

o Exclude corporal, uretheral injuries
o Close with absorbable suture
* Toilet seat most common
o Corporal, urethral injury uncommon

o Torsion of an appendage was the most common diagnosis (46%)
+ Especially age 3- 13
o Epididymitis next (35%)
+ Most common after age 13
o Testicular torsion (16%)
+ Most common cause in first year (86%)

Testicular Torsion
* Failure of fixation between enveloping tunica vaginalis and posterior scrotal wall
o Inappropriately high attachment of the tunica vaginalis
o Bell clapper deformity- found in up to 12% of males
* Left testicle more common
o Bilateral in 10%
* Most aged 12-18 years (peak age 14)
o Smaller peak also occurs in neonatal period in undescended or incompletely descended testes
* Most testes torse lateral to medial
o Typically takes 720 degree turn for ischemia
* Approximately 5-10% of torsed testes spontaneously detorse

Testicular Torsion
* Pain usually sudden, severe
o Scrotum, inguinal region, lower abdomen
* History of physical activity, or trauma
o Fair number occur during sleep
* Up to 50% of patients have prior episodes of intermittent testicular pain
o Nausea and vomiting (20-30%)

o CBC-
+ Mildly elevated in most (60%)
o Doppler US/ nuclear scan
+ Sensitivity of 86%, specificity of 100%, accuracy of 97% when presence of intratesticular flow is the sole criterion
+ Nuclear scan- nearly identical sensitivity (80- 90 %), specificity (75- 95 %)
Testicular Torsion
* Treatment
o Surgical exploration
o Manual detorsion
+ Manual detorsion is successful in 30-70% of patients
+ “Open the book” -

Testicular/ Epididymal Appendage Torsion
* Appendages have no known function
o Appendage testes seen in 92%, epididymal 25%
* Most common cause of acute scrotum
* Peak age 7- 14 (mean 10.6)
* Pain is more intense near the head of the epididymis or testis
* Isolated tender nodule may be palpated
* “Blue dot sign” pathognomonic- 21%
* Treatment-
o Testicular doppler US if unsure
o Most will calcify or degenerate over 10 to 14 days and cause no harm

o Outpatient management
o Oral antibiotics for 10 to 14 days
+ Sexually active
# Need to cover GC, chlamydia, ureaplasma, mycoplasma
# Ceftriaxone, azithromycin
# Consider test for syphilis in sexually active
+ Suspected bacterial
# E. Coli usual pathogen
# Ampicillin, ceftriaxone, gentamicin if toxic
# Amoxicillin, TMP-SX if non-toxic
Mumps
* Most common cause of primary orchitis
* Droplet spread
o As contagious as influenza
* Symptoms 2- 3 weeks after exposure
o Up to 20% asymptomatic
* Uneventful recovery in 2 weeks
* Complications
o Orchitis- Occurs in 20% of symptomatic
+ Swelling of one or both testicles
+ Painful, but rarely leads to sterility
+ Typically unilateral
o Pancreatitis- upper abdominal pain, N/V
o Encephalitis/ meningitis- rare
o Ovarian inflammation- fertility unaffected
o Hearing loss- rare, usually permanent

Orchitis
* Rare
* Bilateral testicular tenderness and swelling over a few days´ duration
* Occurs in conjunction with systemic diseases
o Mumps- occurs on 20% prepubertal (rarely postpubertal)
+ Follows the development of parotitis by 4-7 days
+ Unilateral in 70% of cases
+ Described with MMR vaccine
o Other viral illnesses-
+ Coxsackie virus, infectious mononucleosis, varicella, and echovirus.
o Bacterial orchitis rare
+ Almost always associated with spread from epididymitis
+ Nearly always in sexually active - Neisseria gonorrhoeae, Chlamydia trachomatis, Escherichia coli
+ Unilateral testicular edema occurs in 90% of cases.
* Treatment-
o Symptomatic if concurrent with virus (mumps, mononucleosis)
+ Unilateral testicular atrophy occurs in 60% of patients with orchitis, sterility rare
o Urology evaluation, ultrasound if toxic, diagnosis unclear, suspicion of bacterial orchitis

Undescended Testes
* Testes start descent from inguinal ring at 7th month, complete by birth
* Retractile testes more common
o Cremasteric muscle pulls testicle up
o Should be able to be drawn down into scrotum
+ “Catcher’s position”
o Typically resolves by adolescence
* True, undescended seen in 4% newborn males
o More common in preemies
o Decreases to 0.8% by 1 year
+ Increased risk torsion, trauma, malignancy, infertility
+ Should be corrected if not in normal position by age 1
Scrotal Problems
* Hydroceles
o Incomplete or abnormal obliteration of the processus vaginalis
o Scrotum communicates with abdominal cavity
+ Can lead to diagnostic confusion with appendicitis
o Painless, apparent in neonatal period, disappear by 1 year of age
o Non or minimally compressible scrotal fullness that transilluminates
o US for pain, inability to find testicle, possibility of intratesticular tumor
o Compressibility suggests communicating hydrocele- concurrent inguinal hernia
* Varicoceles-
o Dilated network of veins of pampiniform plexus
o Consequence of spermatic venous valvular incompetence
o Often not noticed until puberty
* Found on the left side (85- 90 %)
o Left spermatic vein drains directly into renalvein
o “Bag of worms” mass posterior, lateral, and superior to the testis extending up the spermatic cord
* Significance
o Untreated can reduce fertility
+ Smaller, softer testicle
o Acute onset, persistence of varicocele when child lies down can suggest rare acute increase in IVC or renal vein pressure (Wilm’s tumor)
* Spermatoceles and Epididymal Cysts
o Sperm-containing cysts of the rete testis or efferent ducts (spermatoceles) or the epididymis (epididymal cysts)
o Painless scrotal masses
+ Located superior and posterior to the testes
+ Transilluminate well
o US shows anechoic mass without disruption of testicle parenchyma
o Treatment-
+ Reassurance- no impact on fertility
+ NSAIDS

Idiopathic Scrotal Edema

o No cause known
+ Differential includes cellulitis, local contact dermatitis, insect bite, fixed drug eruption
o Management-
+ US if unable to examine testes
+ U/A, WBC normal
+ No benefit from steroids, antihistamines, antibiotics
+ Usually resolves in 1- 4 days
+ Recurrence rate up to 20%
Kidney Stones
* Children <16 constitute ~ 7 % of all cases of stones
* 1:1 sex distribution
* Can present at any age- most common age 8-10
* 20- 30 % of children may have only painless hematuria
* Incidence higher in southeast US, hot climates, family history
* Types
o Calcium with phosphate or oxalate (57%)
o Struvite (24%)- associated with infection
o Uric acid (8%)
o Cystine (6%)
* Diagnosis
o Hematuria
+ Spot urine for Spot urinalysis and culture, including ratio of calcium, uric acid, oxalate, cystine, citrate, and magnesium to creatinine
o Helical CT still performs well (97% sensitive, 96% specific)
o Ultrasound better in kids than adults
+ Can be used as first study but still not as good as CT
* Disposition
o Urologic consult
o Admit infants, infected stones, lone kidney, intractable pain, abnormal kidney function, larger stones

Gynecologic Problems
* Labial Adhesions
o Also called vulvar synechiae, gynatresia, vulvar or labial fusion, labial coalescence, agglutination
o Usually seen in girls 3 months to 6 years of age
o Common-
+ Accounts for nearly 50 % of prepubertal gynecologic outpatient complaints
+ Usually asymptomatic
# May have urethritis, UTI
* Labial Adhesions
o Appearance
+ Fusion thin, affects labia minora, doesn’t involve clitoris
+ If thick, may be midline fusion of the labioscrotal folds (median raphe) seen in ambiguous genitalia
o Management
+ Requires no treatment (resolves spontaneously during puberty)
+ Topical estrogen cream (0.1% conjugated estrogen vaginal cream) twice daily for 2 to 4 weeks

* Lichen Sclerosis Atrophica
o Uncommon in prepubertal girls
o Presents with itch, irritation, dysuria, perineal and/or perianal pain, and
bleeding
o May be a coexistent vaginal discharge
o Characteristic appearance- white, atrophic, finely wrinkled vulva
+ Ulcerations, blisters, excoriations, and
inflammation are seen over the vulva, perineum, and perianal area
+ Hourglass or figure-eight pattern
* Lichen Sclerosis Atrophica
o Management
+ Removal of all perineal irritants
+ Systemic antipruritics
+ Local application of an emollient ointment, such as A & D ointment
+ Topical steroids- 2- to 3-month course of treatment with a low-potency topical
steroid cream, such as 2.5% hydrocortisone cream, applied two
to three times daily, is often useful
+ Topical antifungal creams, systemic antibiotics for superinfection
* Urethral prolapse
o Uncommon disorder
o Circular eversion of urethral mucosa through the urethral meatus
o Almost all (90- 100 %) cases occur in black girls
o Etiology unclear
o Typically presents with painless “vaginal”
bleeding
o Doughnut-shaped mass originating from and encircling the urethral meatus, protrudes through the vulva
+ Edematous and friable, often ulcerated
* Urethral prolapse
o Treatment
+ Identify the urethral meatus with certainty
# Observing the child voiding her bladder or by catheterization
+ Don’t confuse with sexual abuse
+ Mild prolapse
# Sitz baths, topical antibiotics, topical steroids, topical estrogen cream (0.1% conjugated estrogen cream to the prolapsed urethra 2-3 times daily for 2 weeks)
# Urologic referral
# Simple manual reduction and urethral catheterization for 1-2 days have been effective in minor cases of urethral prolapse; however, recurrence rates are high
* Urethral foreign bodies
o Bloody urine combined with infection and slow, painful urination should
suggest a possible foreign body in the lower urinary tract
o Management-
+ X- ray of the bladder and urethral areas may show opaque foreign body
+ Endoscopic removal
+ Retrograde urethrography or endoscopic confirmation of an intact, nontraumatized urethra is indicated after removal

Gynecologic Problems Vaginitis
* Affects vulva predominantly in prepubertal girls
* Atrophy from estrogen lack, acidic pH, lack of lactobacilli, poor hygiene
* Most nonspecific- negative cultures or mixed flora
* Group A beta-hemolytic streptococci (GABHS) occasionally causes a beefy red, painful vulvovaginitis
* Shigella also described
o Up to 18% in one study
* Pinworm infection with Enterobius vermicularis is common in prepubertal children
o May present with significant vulvar pruritus, more familiar anal pruritus.
* Candida albicans most frequent fungal
* Noninfectious etiologies- chemical irritation from lotions and bubble baths
* Systemic skin disorders- seborrhea, lichen sclerosis, psoriasis, eczema, and contact dermatitis
* Treatment
o Need to suspect vaginal foreign body
o Supportive care for nonbacterial
+ Wiping front to back
+ Avoidance of tight-fitting garments
* Neonatal vaginal bleeding
o Usually occurs at 3 to 5 days
o Caused by withdrawal of transplacental estrogens
o No treatment except reassurance of parents.

* Hydrocolpos
+ Uterine distension from imperforate hymen, transverse vaginal septum, or atretic vagina
+ Bulging, shiny, pearly gray “mass” is seen covering the introitus
+ Palpable abdominal mass

Pediatric UTI
* Neonatal period-
o UTI in 4- 7% of febrile infants
o Hematogenous seeding of kidneys
* Postneonatal period-
o UTI in 2% of age 1-5
o 3-5% of school aged girls
o Retrograde migration of perineal flora
* Congenital urinary tract anomalies-
o vesicoureteral reflux, urolithiasis
associated with a higher incidence
* Bacteria-
o Escherichia coli accounts for vast majority
o Klebsiella, Proteus, Enterobacter species
o Enterococcus species, Staphylococcus aureus, and group B streptococci
+ Most frequently isolated gram-positives
+ More likely to be causative organisms in the
neonatal period
o Coagulase-negative staphylococcal UTI occurs in teens and young adults
o Other agents
+ Adenovirus cystitis occurs more commonly in young boys
* Testing
o Urine culture gold standard
o Sensitivities of a positive leukocyte esterase or nitrite or a positive urine culture result < 50%
o Combined presence of pyuria (more
than five WBC/ hpf) and bacteriuria
improves sensitivity to 65%
o Positive predictive value of UA is 81 %
* Treatment- 10- to 14-day course in children
* Disposition
o Inpatient management for any child less than 3 months of age with a febrile UTI; significant dehydration, appear toxic, pyelonephritis, urinary stents or other urinary foreign bodies, renal insufficiency, immunocompromise

Pediatric UTI
* Imaging- (IVP, U/S, voiding cystourethrogram)
o all girls less than 5 years of age
o all boys regardless of age
o children with evidence of pyelonephritis
o any female >5 years of age with recurrent UTIs
o those not responding to antibiotics
o Evidence for these recommendations is only fair
o Study all patients with culture-proven UTIs with a voiding cystourethrogram (VCUG) and a renal and bladder ultrasound

Sexual Assault
* Presentation
o Most often, several years have elapsed
* Symptoms
o Disclosure-
o GU symptoms- vaginal discharge, vaginal bleeding, dysuria, urinary tract infections, urethral discharge
o Behavior disturbances- excessive masturbation, genital fondling, sexually provocative behavior, encopresis, regression, nightmares
o Unrelated complaints in 15%- abdominal pain, asthma, sore throat
* Assailant known to the child in > 90 % of cases
* Definite physical findings are present in only about 50% to 60%
o True in cases of known penetration
* Hymen-
o Most often annular, crescentic, and
smooth edged
o Variation in orifice based on age, size,
position, degree of relaxation
* Hymenal trauma
o Notches, also referred to as concavities or clefts
+ Concavities at the 6:00 position associated with prior penetrating trauma
o Scarring- marked alteration in the vascular pattern (white areas or swirling vascularity) suggests healed injury
o Erythema is not specific for abuse

Sexual Abuse
* Genital examination can be confined to a careful inspection of genitalia, perianal area unless older adolescent or perforating vaginal trauma
* Exam, data collection useful up to 72 hours
* Position- seated parent’s lap, supine in frog leg, knee chest
* Toluidine blue dye applied to the genital area may also detect subtle acute
injuries
* Hymen- fine reddish-orange, thin-edged
* Thickness, color of the hymen vary with age
o Normally thick during infancy, again with the onset of puberty
o In between, thinner, usually annular or crescentic, smooth edged
o Wide variation in hymenal orifice size
+ vaginal opening greater than 4- 5 mm is suggestive of abuse
o Erythema is not specific for abuse

Normal Hymen
* Traumatic hymenal changes-
o Hymenal notches or concavities especially at 6:00 position
o Gaping openings
o Irregular contour with deep notches
o Scarring with marked alteration in the vascular pattern (white areas or swirling
vascularity
o Absence of physical findings does not preclude abuse
Abnormal Hymen
Sexual Abuse
* Genital exam in young boy typically normal
* Anal exam may be completely normal in the case of either acute or chronic
sodomy
o May see fissures, abrasions, hematomas, thickened rugae, lichenification of anal skin, changes in tone, fingerprint bruises on iliac wing, inner thigh
Abnormal Anus
STD Protection

* Cultures of the throat, vagina (or urethra), and rectum for gonorrhea
* Culture from the vagina (or urethra) for Chlamydia
o Rapid antigen assays are not considered reliable in prepubescent children
* VDRL for syphilis indicated if clinical evidence of syphilis, history of syphilis in assailant, or presence of another STD
* HIV testing should only be done after counseling and if there is reason to suspect infection
Pediatric Genitourinary
* Conclusions
o Obtain culture on all kids less than teen years
o Always examine the testicles in boys with abdominal pain
o Consider ketamine if need exam, repair in ER

Before and after fistula repair



Before and after fistula repair

Tracheoesohpageal fistula

An omphalocele is an abdominal wall defect at the base of the umbilical cord (umbilicus); the infant is born with sac protruding through the defect which contains small intestine, liver, and large intestine.

Gastroschisis:
Surgical repair of abdominal wall defects involves replacing the abdominal organs back into the abdomen through the abdominal wall defect, repairing the defect if possible, or creating a sterile pouch to protect the intestines while they are gradually pushed back into the abdomen.

Anorectal malformations; Anal atresia
Imperforate anus is a relatively common congenital malformation that occurs in about 1 out of 5,000 infants.
signs & symptoms
o absence of anal opening
o misplaced anal opening
o anal opening very near the vaginal opening in the female
o no passage of first stool within 24 to 48 hours after birth
o stool passed by way of vagina or urethra
o Abdomianl distention
o vomiting if infant is fed
o Asymmetry in leg positions
o Asymmetry of the thigh fat folds
o After 3 months of age, asymmetry of rotation of the leg and apparent shortening of the affected leg
o Diminished movement in the affected side

Signs & tests
Pediatricians routinely screen all newborns and infants for hip dysplasia. There are several maneuvers that can detect a dislocated hip or a hip that is able to be dislocated. A hip that is truly dislocated in an infant should be picked up but some cases are subtle and some develop after birth, which is why multiple examinations are recommended. Some mild cases are "silent"; and cannot be picked up on physical exam.

Ultrasound of the hip is the most important imaging study and will demonstrate hip deformity. A hip X-ray joint X-ray) is helpful in older infants and children.

Treatment
In early infancy, positioning with a device to keep the legs apart and turned outward (frog-leg position) will usually hold the femoral head in the socket. If there is difficulty in maintaining proper position, a plaster cast may be applied and changed periodically to accommodate growth. Operative management may be necessary if early measures to reduce the joint (put the joint back in place) are unsuccessful, or if the defect is first detected in an older child.

Prognosis
If the dysplasia is picked up in the first few months of life, it can almost always be treated successfully with bracing. In a few cases surgery is necessary to put the hip back in joint.The older the age at diagnosis, the worse the outcome and the bigger the surgery needed to repair the problem.

Talipes equinovarus; Talipes or Clubfoot
Signs & Symtptoms:
The physical appearance of the deformity may vary.
Treatment should be initiated as early as possible.
Polydactyly
Fingers or toes (digits) may be fused together (syndactyly) or the webbing between them (inter-digital webbing) may extend far up the digits. Syndactyly is seen commonly between the 2nd and 3rd toes, and is usually associated with a syndrome.
Signs & symptoms
Treatment
Epispadias
Malignant teratoma
Inborn errors of metabolism
TYPES & OTHER NAMES:
Galactosemia - nutritional considerations; Fructose intolerance - nutritional considerations; Maple sugar urine disease (MSUD) - nutritional considerations; Phenylketonuria (PKU) - nutritional considerations; Branched chain ketoaciduria - nutritional considerations

DEFINATION:
Genetic disorders (numbering in the dozens) in which the body cannot metabolize food components normally. These disorders usually involve minute changes in the breakdown of proteins, fats and carbohydrates. The body can become malnourished even when eating a well-balanced diet. See also galactosemia, PKU, lactose intolerance, and maple syrup urine disease

RECOMMENDATION
Inborn errors of metabolism often demand diet changes. The type and extent of the changes depends the specific metabolic error. Registered dietitians and physicians can help with the diet modifications needed for each disease.

Symptoms
o jaundice (yellowish discoloration of the skin and the whites of the eyes)
o vomiting
o poor feedig
o poor weight gain
o lethargy
o irritability
o convulsions
o pupil, white spots

Signs & tests
o hepatomegaly (enlarged liver)
o hypoglycemia (low blood sugar)
o aminoaciduria (amino acids are present in the urine)
o cirrhosis
o ascites (fluid collects in the abdomen)
o mental retardation
o cataract formation
Galactosemia
PRGNOSIS:
Phenylketonuria
Causes & risks
SIGNS & SYMPTOMS OF PKU
Trisomy 18 also known as Edwards syndrome
SIGNS & SYMPTOMS OF EDWARDS
Down syndrome; Trisomy 21; Mongolism
SIGNS & SYMPTOMS OF DOWNS
Common autosomal aberrations
