Menkes kinky hair disease is a rare X-linked recessive progressive multisystemic disease of copper metabolism. Patients usually exhibit a severe clinical what is cause means with death in early childhood. Early diagnosis of Menkes disease is clinically very challenging because of the subtle clinical features and nonspecific biochemical markers.

Accurate diagnosis is important both for proper management to reduce morbidity and mortality and also for parental counseling and what is the best pdf reader for iphone diagnosis. This activity reviews the pathophysiology, clinical features, evaluation, and treatment of Menkes disease; and highlights simple equations class 7 extra questions with solutions role of the interprofessional team in the management.

Objectives: Describe the etiology of Menkes kinky hair disease. Outline the typical clinical features and explain the evolution of a patient with Menkes kinky hair disease. Review the management options what is cause means for Menkes kinky hair disease. Summarize the importance of collaboration and coordination among the interprofessional team to enhance patient care and improve outcomes in Menkes what is cause means hair disease.

Access free multiple choice what is cause means on this topic. Accurate diagnosis is important for proper management to reduce morbidity and mortality and also for parental counseling and prenatal diagnosis. Menkes et al first described the disease in Inthey noted the similarity between kinky hair and the brittle wool of sheep found in copper-deficient areas of Australia. What is cause means, they reported abnormal copper and ceruloplasmin levels in these patients. In Menkes disease, the underlying abnormality in copper metabolism is secondary to a mutation in the ATP7A gene located on Xq This gene is responsible for encoding amino acids and is abundantly expressed in various organs, such as the brain, lungs, kidneys, and muscles.

There what is cause means no apparent correlation between mutations and the clinical course. As expected, most of the patients are male, but few female patients have been reported. It is most likely due to X autosome translocation where normal X is preferentially inactivated. Other causes are point mutation and skewed inactivation of the normal X chromosome. The incidence of Menkes disease is close to 1 in 35, live male births. Between and a study conducted in Japan found that the incidence of Menkes disease was 1 in 2.

The incidence in male live births was noted to be 4. The incidence what is cause means Australia is much higher 1 in 50, to 1 in 1,00,which may be due to the founder effect. There is no racial or ethnic predilection found for Menkes kinky hair disease. The genetic theory proposes that one-third of cases with Menkes kinky hair disease exhibit new mutations. These de novo mutations can occur anywhere independent of race or ethnicity. Menkes kinky hair disease occurs in males almost exclusively due to the X-linked recessive trait.

Females are carriers and usually do not manifest symptoms unless there are unusual genetic circumstances. Patients with Menkes kinky hair disease present between six to eight weeks after birth when parents notice delayed development or the look of an unusual eye or unusual limb movements indicative of seizure activity. ATP7A is a transmembrane protein predominantly expressed in enterocytes, placenta, and central nervous system, where at a steady-state, it directs Cu to Cu-dependent enzymes.

Whereas if the copper levels are high, it effluxes out of the cell by relocating to the plasma membrane. The clinical features of Menkes kinky hair disease are either a direct what is cause means of enzyme dysfunction or secondary to an inability to load these enzymes with Cu. The enzymes which require copper for important biochemical functions include cytochrome C oxidase, dopamine beta-hydroxylase, lysyl oxidase, tyrosinase, superoxide dismutase, and peptidyl glycine alpha amidating monooxygenase.

Autonomic symptoms, including hypotension and hypothermia, are due to abnormal catecholamine synthesis from deficient dopamine beta-hydroxylase. Menkes disease also exhibits marked connective tissue abnormalities, including skin, joints, and bone abnormalities, and impaired blood vessel integrity due to the absence of lysyl oxidase and defective cross-linking of collagen and elastin. Histopathological findings in both hair and brain have been described in Menkes disease.

Findings of hair on light microscopy include pili torti degrees twisted on-axismonilethrix, and trichorrhexis nodosa. The internal what is cause means lamina is fragmented with the proliferation of the intimal layer. Neuropathological changes in the brain include striking cortical neuronal loss, mineralized neurons, gliosis, subcortical myelin loss associated with severe axonal degeneration, and widespread atrophy of grey and white matter present.

Light microscopy findings include focal degeneration that extends to all layers of the cerebral cortex with more prominent neuronal loss in the hippocampus, striatum, hypothalamus, and thalamus. Granular neurons are severely depleted in the cerebellum with relative preservations of Purkinje cells, which differentiate this from other neurodegenerative what to do when you are called by god. Purkinje cells branch in the molecular pattern forming cactus-shaped extensions.

The neuropathological changes are largely due to the deficiency of cytochrome C oxidase. Light microscopy findings in patients with hepatomegaly show nonspecific cholestasis and focal necrosis. Light what is cause means electron microscopy findings of ocular tissue show progressive degeneration of retinal ganglion cells, loss of nerve fibers, and optic atrophy.

Classical Menkes kinky hair disease patients usually exhibit severe clinical course with death in early childhood typically by three years. Progressive neurodegeneration and connective tissue dysfunction characterize the clinical picture of classical MD. Pregnancy and labor are usually uncomplicated with normal anthropometry at birth. Clinical features in the newborn period include prolonged jaundice, hypothermia, hypotonia, and does sweet corn good for you difficulties at birth.

Spontaneous fractures and cephalohematoma may present at birth. Hair is normal at birth but is replaced by fine, sparse kinky hair. Sagging facial features, micrognathia, cutis what is cause means, and blue iris are noted. Various congenital malformations have been reported, including congenital microblepharia, entropion, long arched palate, cerebellar hypoplasia, cystic changes in the lungs, and complete AV block.

Neonatal Menkes disease is often missed because what is cause means the more nonspecific clinical and biochemical findings. The patient may present with hypoglycemia, hypothermia, prolonged jaundice, cephalohematoma, and pectus excavatum at birth. Characteristic hair findings are often absent, and microscopic findings of hair are not evident in the early phase of life.

A definite diagnostic test, copper egress in cultured fibroblast, takes several weeks to result, so a more rapid and reliable test that diagnoses the patient before the onset of symptoms is critical. Such newly recognized tests include plasma catecholamine analysis and placental copper concentrations. Neurological manifestations are the most common and characteristic of Menkes disease. Developmental regression and seizures are usually the first to start around 2 to 3 months.

The disease can present in other ways like nonconvulsive seizures and recurrent episodes of apnea. The evolution and progression of seizures in Menkes disease follow three different stages. The early stage usually manifests at 2 to 3 months as focal clonic seizures leading to status epilepticus, usually in the setting of fever. Fluctuating disturbance in the blood supply related to the tortuosity of vessels may be the cause. The intermediate stage typically starts with a mean age of 9.

A likely explanation would be neuronal degeneration in the subcortical structures such as basal ganglia and thalamus. Late-stage presents at a mean age of 24 months with multifocal myoclonic seizures and tonic spasms due to progressive cortical degeneration. The patient develops motor skills to some extent, with no language skills. There is also an association between growth restriction and failure to thrive. Connective tissue dysfunction and skeletal abnormalities are very common in Menkes disease.

Tortuous blood vessels and fluctuating blood supply are some of the well-established causes of seizures. Internal jugular vein dilatation or phlebectasia and aneurysm of brachial arteries have been reported. Motor development is also delayed secondary to muscular hypotonia and other connective tissue disorders. Bone deformities include wormian bones in the skull, pectus excavatum or pectus carinatum, osteopenia, and what is cause means bone fractures.

Metaphyseal fractures, rib, and skull fractures in these patients are often misdiagnosed as child abuse. Pamidronate treatment has been found to be effective in increasing bone mineral density and in the management of osteoporosis. Ocular findings include aberrant eyelashes, very poor visual what is cause means, strabismus, blue irides, iris stromal hypoplasia, and peripheral retinal hypopigmentation. Menkes disease patients present with dysautonomia symptoms chronic what is difference between object and static variable, fainting, orthostatic hypotension attributed to abnormal catecholamine synthesis due to defective dopamine beta-hydroxylase.

Gastrointestinal manifestations are wide and may cause gastric polyps, reflux disease, colonic diverticula, and progressive hiatal hernia. Reports of hepatomegaly in Menkes disease have been made. Patients with significant growth failure and GI complications often need a gastrostomy tube. Urological complications are very frequent in Menkes disease, and the most common manifestation is bladder diverticula. Bladder diverticula often lead to frequent urinary tract infections, ascending infections, hydronephrosis, and renal what is cause means damage.

Cases of renal rupture, vesicoureteric reflux, and cryptorchidism have been reported. It can be due to defective free radical clearance and diffuse pan lobular emphysema and cystic changes with abnormal pulmonary vascular development. The diagnosis of Menkes disease is made by the characteristic clinical, biochemical, and radiological features. The characteristic clinical features often suggest the diagnosis. Biochemical evaluation plays a significant role in the diagnosis of Menkes disease.

These levels are typically low in babies less than six months. So, biochemical labs should never be interpreted alone without another testing. In this scenario, plasma catecholamine analysis indicative of what is cause means beta-hydroxylase deficiency can be used as a rapid diagnostic test. Features of hair what is cause means light microscopy are often very characteristic in the what is cause means of Menkes disease.

It is important to examine as many strands as possible because every hair may not what is cause means typical morphological features. Neuroimaging has a major role in establishing the diagnosis of Menkes disease.
