Pseudotumor Cerebri

Definition.
– Raised intracranial pressure with papilledema
and a normal cerebrospinal fluid in the
absence of ventricular enlargement.
 Risk
– Obesity occurs in 30%-80% of affected children.
• Scott Am J Opth 1997; 124:253-255
– In a series of case-controlled studies in adolescents and
adults, obesity and recent weight gain were the only
factors found significantly more often in pseudotumor
cerebri patients than control patients.
• Lessell S. Surg Ophthalmol 1992;37(3):155-66.
Pseudotumor Cerebri

Diagnosis
– May present with headaches, vomiting, blurred vision or
diplopia.
– Neck, shoulder, and back pain have also been reported.
• Lessell S. Surv Ophthalmol 1992;37(3):155-66.

Loss of peripheral visual fields and reduction in visual
acuity may be present at diagnosis
• Baker RS, Carter D, Hendrick EB, Buncic JR. Arch Ophthalmol
1985;103(11):1681-6.

Increased intracranial pressure may lead to visual
impairment or blindness.

Treatment
– Acetazolamide
– Lumboperitoneal shunt (in severe cases),
– Weight loss
• Newborg B. Arch Intern Med 1974;133(5):802-7.

Points to Remember

A fundiscopic examination should be a
routine part of the examination of the obese
child
 Children may not complain of visual field
disturbances. When suspicious – test
 Pseudotumor cerebri is essentially a
diagnosis of exclusion after other causes of
increased intracranial pressure are
eliminated.
Slipped Capital Femoral Epiphysis

Diagnosis
– Suspect and immediately evaluate in an
obese patient who presents with limp.
– 50%-70% patients with SCFE are obese.
• Wilcox J Pediatr Orthop 1988:8:196-200.
– Can also present with complaints of groin,
thigh, or knee pain referred by obturator
nerve
Slipped Capital Femoral Epiphysis

Diagnosis
– Motion of the hip in abduction and internal rotation
is limited on examination.

X- ray
– Anteroposterior view of the pelvis and frog leg that
includes both hips.
– Comparison of the hips
– Bilateral disease occurs in up to 20% of patients.

Intervention
– Requires surgical correction and weight loss.
SCFE-Pathology

Medial and posterior displacement of the
femoral epiphysis through the growth plate
relative to the femoral neck
• Busch MT, Morrissy RT. Orthop Clin North Am 1987;18(4):637-47.

The preferential site of slipping within the
epiphysis is a zone of hypertrophic cartilage
cells under the influence of both gonadal
hormones and growth hormone
• Kempers MJ, Noordam C, Rouwe CW, Otten BJ. CanJ Pediatr
Endocrinol Metab 2001;14(6):729-34.

.
SCFE - Associated Causes

Continued weight gain.
 Renal failure
 History of radiation therapy
 Primary hypothyroidism.
• Loder RT, Greenfield ML.. J Pediatr Orthop . 2001;21(4):481-7.

Gonadotropin-releasing hormone agonists
 Growth hormone therapy
• Kempers MJ, Noordam C, Rouwe CW, Otten BJ. J Pediatr
Endocrinol Metab 2001;14(6):729-34.
• Grumbach MM, Bin-Abbas BS, Kaplan SL. Horm Res
1998;49(Suppl 2);41-57.
Blount’s disease
Bowing of tibia and femur
either unilateral or bilateral.
2/3 of patients with Blount’s
disease may be obese.
Dietz J Pediatr 1982:101:735-737
.
•Blounts Disease
Blount’s Disease - Obesity Related
Orthopedic Morbidity

Etiology
– Injury to the growth plate, fissuring and clefts
in the physis as well as fibrovascular
and cartilaginous repair tissue at the physealmetaphyseal junction.
– .Wenger DR, Mickelson M, Maynard JA.J Pediatr Orthop.
1984 Jan;4(1):78-88.

– Results from overgrowth of the medial aspect
of the proximal tibial metaphysis.
Treatment
– Requires evaluation and correction by
orthopedic surgeon.
– Weight loss
Blount’s disease
Points to Remember



A careful hip and knee examination should be a
routine part of the evaluation and follow-up of every
obese child.
An obese child complaining of or presenting with hip,
knee, groin, or thigh pain should have a complete
and thorough examination of his/her hips, including
radiological studies.
In an obese child, an unusual or abnormal gait should
not be attributed to “excess weight” but should be
thoroughly investigated with a careful hip and knee
examination.

Upper Airway Obstructive Sleep
Apnea Syndrome

Structure
– Adipose tissue in upper airway contributes to
Upper Airway Obstruction
•
Shelton KE, et al Pharyngeal fat in obstructive sleep apnea. Am Rev Respir
Dis. 1993;148(2):462–466
– Abdominal adiposity may compromise
respiratory excursion
•
Kessler R et al The obesity-hypoventilation syndrome revisited: a prospective study of 34
.
consecutive cases. Chest. 2001;120(2):369–376

Function
– Infiltration of adipocytes into diaphragmatic
muscles may alter respiratory mechanics
• Fadell E et al. Fatty infiltration of the respiratory muscles in the
Pickwickian syndrome. N Engl J Med. 1962;266(17):861–863.
Obstructive Sleep Apnea

OSAS in children is defined as a disorder
of breathing during sleep characterized
by.
– prolonged partial upper airway
obstruction.
– and/or intermittent complete
obstruction (obstructive apnea).
– that disrupts normal ventilation during
sleep and normal sleep patterns.
• Schechter MS. Technical report: diagnosis and management of
childhood obstructive sleep apnea syndrome. Pediatrics
2002;109(4):e69-79.
Airway Mechanics:

Dynamic relationship:
– Negative intra-thoracic
pressure during
inspiration:
• Always a closing
pressure
– Airway size and shape:
• This may favor airway
opening or closure
– Airway tone:
• Tissue rigidity
• Neuromuscular:
– Too much: Airway
constriction
– Too little: Airway Fricke, BL et al: Korean J Radiol 8(6), December 2007
collapse
Obstructive Sleep Apnea Effects

Cognitive
– Decreases in learning and memory.
• Rhodes J Pediatr 1995;127:741-744.
– Deficits in attention, motor efficiency and graphomotor ability.
• Greenberg GD, Watson RK, Deptula D.. Sleep 1987;10(3):254-62.

Cardiopulmonary
– Pulmonary hypertension,systemic hypertension, right heart
failure.

• Massumi RA, Sarin RK, Pooya M, Reichelderfer Dis Chest 1969;55(2):110-4.

Sleep disturbance
– Weight >200% above ideal had oxygen saturation <90% for half to total sleep time.
– 40% of severely obese children demonstrated central hypoventilation.

OSAS-diagnosis

Symptom checklists in research settings
• Chervin RD et Sleep Med. 2000;1(1):21–32


History, audio and video taping, and overnight
oximetry and daytime nap polysomnography are
poor predictors of OSAS.
The definitive diagnosis of OSAS is made by
nighttime polysomnography.
• Clinical practice guideline: Pediatrics 2002;109(4):70412.

Severity of obstruction may not correlate with
either degree of obesity or severity of sleep
symptoms.
Treatment

Definitive treatment is weight loss
• Willi SM et al Pediatrics. 1998;101(1 Pt 1):61–67.


Tonsil/Adenoidectomy-temporizing
CPAP/BIPAP-Titrated in sleep lab
• Marcus CL et al.J Pediatr. 1995;127(1)(((3):88–94.

Extreme cases unresponsive to weight
loss/BiPap/CPAP uvulopharyngopalatoplasty,
craniofacial surgery, and, in severe cases,
tracheostomy
• Section on Pediatric Pulmonology, Pediatrics. 2002;109(4):704–
712.

Gastric Bypass/Banding in adults
Points to Remember



Ask specifically about sleep disturbances, snoring,
and sleep position. Families will often disregard these
symptoms.
Obstructive sleep apnea syndrome should be
especially considered in obese children with poor
school performance and concentration difficulties.
Sleep symptoms can evolve over time. Keep asking
about sleep disturbance as you follow these children.
Weight gain, intercurrent upper respiratory infections,
and Tonsillar enlargement can provoke symptoms.

Non Alcoholic Steatohepatitis - Obesity

Diagnosis
– Increased liver enzymes and fatty liver on ultrasound in
the absence of other causes of liver disease.
– Rule out other causes of fatty liver
– Liver Biopsy

Etiology
– 20%-25% obese children have evidence of
steatohepatitis.
– Tazawa Acta Paeditr 1997;86:238-241.
– Obesity and type 2 diabetes are the strongest predictors
of progression of fibrosis
– Age is also a risk factor for cirrhosis which may reflect
increased duration of risk for the “second hit” thought
to initiate fibrosis.

Obesity Trajectory and Depression/ODD



Chronically obese children had significantly
higher rates of oppositional defiant disorder, and
(for boys) depression.
No difference among groups in gender, family
structure, parenting style, family history of mental
illness, drug abuse, crime, or traumatic events.
Chronic and childhood obesity were associated
with having uneducated parents and low family
income.

Health related quality of life

Obese children and adolescents 5.5 times
more likely to have impaired health related
quality of life than normal weight child
 Reported lower pediatric health related
quality of life cores in all domains,
physical, psychosocial, emotional, social, and
school functioning than healthy children
and adolescents
 Parents scores were even lower than
children's

Health related quality of life

Obese children and adolescents with OSA
reported lower quality of life scores than
other obese children
 Health-related QOL did not vary by age,
sex, SES, or race
 BMI z score among obese children and
adolescents was inversely correlated with
physical functioning.

Comorbidities of Obesity
Complete evaluation of an obese
child includes history, review of
systems and physical which includes
obesity related comorbidities.
 Treatment of obesity reduces
morbidity
 Modest weight loss is effective in
ameliorating effects of obesity
related comorbidities.
