RESUMEN
The association between Morgagni hernia and Menkes disease has not yet been described. Here, we report such a rare association in an 8-year-old boy who presented with subocclusive symptoms. He successfully underwent laparoscopic repair with a patch. The patch was fixed to the anterior abdominal wall by using transfascial sutures with extracorporeal knot tying and to the remaining edges of the diaphragmatic defect by using intracorporeal suturing and spiral tacks. At the 2-year follow-up, the child remained recurrence-free and without gastrointestinal symptoms. The potential relationship between the two conditions and the controversial use of spiral tacks to affix the mesh to the diaphragm are also discussed.

Menkes disease is an X-linked recessive disorder affecting copper metabolism due to an inactivating mutation of ATP7A gene. This result in loss of copper intestinal absorption, tissue deficiency and failure in multiple essential copper-enzyme systems such as the cytochrome c oxidase. Symptoms usually occur during the first months of life with neurological signs such as epilepsy associated to other signs among them typical hair appearance. We report the case of a 3 month-old infant hospitalized due to partial tonic-clonic seizures. Laboratory findings showed increased of lactates in blood and in cerebrospinal fluid. First screenings for infectious, metabolic and genetic causes were negative. After recurrence of multifocal seizures further investigations are made according to the presence of thick and tortuous hair. Low levels of ceruloplasmin and copper in plasma are in agreement with the suspected diagnosis of Menkes disease. Molecular analysis of the ATP7A gene confirmed the diagnosis with a non-sens mutation.

Introducción: presentamos el caso de un paciente con antecedentes de polineuropatía amiloidótica familiar por transtiretina (TTR-FAP) diagnosticado de hipocupremia severa. Caso clínico: varón de 79 años afecto de TTR-FAP. Visto en consulta de nutrición por desnutrición severa. En el estudio analítico presenta cifras de cobre (Cu) sérico y ceruloplasmina bajas, con Cu en orina también bajo. No tiene clínica digestiva ni antecedentes de cirugía gastrointestinal. Las pruebas de función hepática, la ferrocinética, las cifras de Hb y leucocitos y los niveles de zinc (Zn) no presentan alteraciones relevantes. Discusión: el Cu es un oligoelemento que participa como componente de las cuproenzimas en múltiples funciones fisiológicas. Los niveles séricos bajos pueden relacionarse con causas genéticas o adquiridas, como la baja ingesta, la cirugía bariátrica, el aumento de las pérdidas, etc. Las principales manifestaciones clínicas son hematológicas (anemia, leucopenia) o neurológicas (mielopatía, neuropatía periférica). El tratamiento tiene base empírica. En los casos severos puede iniciarse con administración intravenosa, seguido de mantenimiento por vía oral
Introduction: we report a patient with transthyretin familial amyloid polyneuropathy (TTR-FAP) and severe hypocupremia. Case report: a 79-year-old male with TTR-FAP and severe malnutrition. Laboratory tests showed low serum copper (Cu) and ceruloplasmin levels, as well as low urinary Cu levels. The patient reported neither digestive symptoms nor previous gastrointestinal surgery. Liver function tests, iron metabolism, hemoglobin, leukocytes and zinc were normal. Discussion: Cu is a trace element. It is part of the cuproenzymes involved in several physiological functions. Hypocupremia can be related to genetic or acquired etiologies, including low intake, bariatric surgery, increased losses, etc. Primary clinical manifestations include hematological (anemia and leukopenia) and neurological (myelopathy, peripheral neuropathy) features. Treatment is empirical. In severe cases it may be initiated with endovenose administration, followed by oral supplementation

Menkes disease, or Kinky Hair Syndrome, is a rare disorder of copper metabolism that causes fatal neurodegenerative disease in infancy. This X-linked disorder results from mutations in the ATP7A gene. Along with neurological decline, characteristic coarse appearance of the hair is seen. Urological issues are prevalent in this patient population, with bladder diverticula being the most common. Herein, we describe a unique male patient with genetic mosaicism and osseous metaplasia found in a ruptured bladder diverticulum.

BACKGROUND: Koolen-de Vries (KdV) syndrome is caused by a 17q21.31 deletion leading to clinical symptoms of hypotonia and developmental delay and can present with abnormal hair texture. Menkes disease is an X-linked recessive inherited disease caused by pathogenic variants in ATP7A, which leads to profound copper deficiency. METHOD: We identified an infant male who presented with prematurity, hypotonia, and dysmorphic features for whom a family history of clinical Menkes disease was revealed after discussion with the clinical genetics team. RESULTS: Although initial first-tier genetic testing identified Kdv syndrome (17q21.31 syndrome), the family history led the team to consider a second diagnostic possibility, and testing of ATP7A revealed a pathogenic variant (c.601C>T, p.R201X). CONCLUSION: Menkes disease and KdV syndrome may both present with hypotonia and abnormal hair, in addition to seizures and failure to thrive. While these genetic conditions have overlapping clinical features, they have different natural histories and different therapeutic options. Here, we report on a patient affected with both disorders and review the diagnostic and therapeutic difficulties this presented.

Menkes disease (MD) usually presents in infancy with respiratory and neurological complications. Severe isolated vasculo-connective tissue involvement in infancy is rare, and hence the precise and timely diagnosis is difficult. We report a case of an 8-week-old male infant who succumbed to acute, severe exsanguination, and hemorrhagic shock secondary to a large retroperitoneal hematoma due to rupture of a right iliac artery aneurysm. Perimortem musculoskeletal findings raised suspicion of nonaccidental injury. However, postmortem review of facial traits raised the suspicion of MD. MD was subsequently confirmed on genetic testing. Child health clinicians must remain aware of MD as a rare cause of infant vasculopathy or atypical skeletal abnormalities.

BACKGROUND: Menkes disease (MD) is a rare X-linked hereditary multisystemic disorder that is caused by dysfunction of copper metabolism. Patients with MD typically present with progressive neurodegeneration, some connective tissue abnormalities, and characteristic "kinky" hair. In addition, various types of urological complications are frequent in MD because of underlying connective tissue abnormalities. In this study, we studied the clinical features and outcomes of MD, focusing on urological complications. METHODS: A total of 14 unrelated Korean pediatric patients (13 boys and 1 girl) with MD were recruited, and their phenotypes and genotypes were analyzed by retrospective review of their medical records. RESULTS: All the patients had early-onset neurological deficit, including developmental delay, seizures, and hypotonia. The girl patient showed normal serum copper and ceruloplasmin levels as well as milder symptoms. Mutational analysis of the ATP7A gene revealed 11 different mutations in 12 patients. Bladder diverticula was the most frequent urological complication: 8 (57.1%) in the 14 patients or 8 (72.7%) in the 11 patients who underwent urological evaluation. Urological imaging studies were performed essentially for the evaluation of accompanying urinary tract infections. Four patients had stage II chronic kidney disease at the last follow-up. CONCLUSION: Urologic problems occurred frequently in MD, with bladder diverticula being the most common. Therefore, urological imaging studies and appropriate management of urological complications, which may prevent or reduce the development of urinary tract infections and renal parenchymal damage, are required in all patients with MD.

RATIONALE: Menkes disease (MD), also known as Menkes kinky hair disease, is a fatal neurodegenerative disease caused by a defect in copper metabolism. The symptoms involve multiple organ systems, such as the brain, lung, gastrointestinal tract, urinary tract, connective tissue, and skin. There is currently no cure for this disease entity, and patients with the classic form of MD usually die from complications between 6 months and 3 years of age. Intracranial hemorrhage secondary to tortuous intracranial arteries is a well-known complication of MD, but spontaneous retroperitoneal hemorrhage, to the best of our knowledge, has never been reported in a patient with MD. Herein, we describe the first case of retroperitoneal hematoma as a complication of MD in a 4-year-old boy. PATIENT CONCERNS: A 4-year-old Taiwanese male patient with MD was referred to the hospital and presented with a palpable epigastric mass. DIAGNOSES: On the basis of the findings of ultrasonography and enhanced computed tomography, the diagnosis was retroperitoneal hematoma. INTERVENTIONS: Interventions included laparotomy with evacuation of the hematoma, manual compression, and suture of the bleeding vessels. OUTCOMES: There were no postoperative complications. LESSONS: This case emphasizes that bleeding in patients with MD is possible at any site in the body owing to the unstable structure of the connective tissues. Timely diagnosis with proper imaging studies can lead to prompt and appropriate management and save patients from this life-threatening condition.

In paediatrics, one of our main aims in the diagnostic process is to identify any treatable conditions. The copper metabolism disorder Wilson's disease (WD) is one such condition that is caused by mutations in the ATP7B gene. Delay in treatment could result in irreversible disability or even death. Although liver disease is the most common presenting feature in children, some children may initially present with a subtle neurological presentation only. In patients presenting with dystonia, tremor, dysarthria or with a deterioration in school performance, there should be a high index of suspicion for WD. However, the differential of these clinical presentations is wide and exclusion of WD is difficult. No single diagnostic test can exclude WD and each of the biochemical tests has limitations. In this article, we discuss copper metabolism disorders including WD and Menke's disease. We then discuss the available diagnostic tests and how to investigate children for these rare disorders.

Bajas concentraciones séricas de Cu en neonatos pueden ser la primera señal de una ingesta deficiente de este elemento o, alternativamente, de enfermedades genéticas que afectan su metabolismo. Desgraciadamente, es difícil la interpretación de las concentraciones de Cu en esta población, ya que están influenciadas por distintos factores, entre ellos la prematuridad, el tipo de alimentación y la presencia de un estado inflamatorio. Sin embargo, en el caso que aquí se describe fue la baja concentración sérica de Cu la primera pista para el diagnóstico de enfermedad de Menkes. Se demuestra así la utilidad de la determinación de Cu dentro de protocolos neurometabólicos y de retraso psicomotor en población neonatal y lactante (AU)
Low serum Cu concentrations in newborns can be the first indication of a severe Cu deficient intake or, alternatively, of genetic diseases affecting Cu metabolism. Unfortunately, interpretation of serum Cu concentrations in this population is difficult because they also influenced by several variables, such as, prematurity, type of feeding and inflammatory conditions. However, in the case described in this paper was a low serum Cu concentration the first clue for diagnosing Menkes disease. It is so demonstrated the usefulness of Cu determination within neurometabolic or psychomotor retardation protocols for newborn and infant populations (AU)

BACKGROUND: Menkes disease (MD) is a disorder of copper metabolism due to ATP7A gene mutation that leads to severe copper deficiency. Deformed blood vessels can be found in many parts of the body, and intracranial hematoma is generally reported. METHODS: We report a Taiwanese boy with MD who had recurrent spontaneous subserosal hematoma of ileum presenting as intestinal obstruction, with the 2 episodes 23 months apart. The patient returned to the usual physical status after surgical removal of the hematoma. RESULTS: The defective copper metabolism causes dysfunction of a plenty of copper-dependent enzymes, giving rise to unique kinky hair appearance, progressive neurodegeneration, and connective tissue abnormalities. To our knowledge, this is the first report on recurrent subserosal hemorrhage of intestine in MD. CONCLUSION: Owing to the fragile structure of blood vessels, subserosal hematoma should be considered when patients with MD having intestinal obstruction.

Copper is an essential metal ion that provides catalytic function to numerous enzymes and also regulates neurotransmission and intracellular signaling. Conversely, a deficiency or excess of copper can cause chronic disease in humans. Menkes and Wilson disease are two rare heritable disorders of copper transport that are characterized by copper deficiency and copper overload, respectively. Changes to copper status are also a common feature of several neurodegenerative disorders including Alzheimer's disease (AD), Parkinson's disease (PD) and Amyotrophic lateral sclerosis (ALS). In the case of AD, which is characterized by brain copper depletion, changes in the distribution of copper has been linked with various aspects of the disease process; protein aggregation, defective protein degradation, oxidative stress, inflammation and mitochondrial dysfunction. Although AD is a multifactorial disease that is likely caused by a breakdown in multiple cellular pathways, copper and other metal ions such as iron and zinc play a central role in many of these cellular processes. Pioneering work by researchers who have studied relatively rare copper transport diseases has shed light on potential metal ion related disease mechanisms in other forms of neurodegeneration such as AD.

Background: Menkes disease is a disorder of copper transportation that results in multi-systems involvement including neurological deterioration, seizure, dysmorphic facies and kinky hair. The authors report a case of Menkes disease that was complicated with bilateral iliac artery aneurysms. Case Report: A 6-month-old Thai male infant presented with seizure, global delayed development, hypotonia and sparse, short, lightly pigmented and kinky hair. Light microscopic hair analysis showed pili torti. His serum copper and ceruloplasmin levels were low and were compatible with Menkes disease. Radiological finding from magnetic resonance angiography (MRA) revealed irregular tortuosity of abdominal aorta, a large right internal iliac artery aneurysm and a small left common iliac artery aneurysm. Genetic counseling and supportive treatment were provided for this patient. Conclusion: Iliac aneurysms are a serious complication of patients with Menkes disease. Careful investigation with computed tomographic angiography (CTA) or MRA is helpful in those patients.

Menkes syndrome is a genetic disorder of copper metabolism, often with urologic complications, including bladder diverticula and vesicoureteral reflux. A 1-year-old boy with Menkes syndrome presented with recurrent urinary tract infections and incomplete bladder emptying secondary to 2 large bladder diverticula. He underwent robot-assisted excision of both diverticula with subsequent improved emptying and resolution of urinary tract infections. There is no consensus on management of bladder diverticula in Menkes syndrome. Because the life span of these patients is significantly shortened, one must select an intervention based on their clinical condition, potential morbidities, and informed expectations of the family.

ATP7A mutations impair copper metabolism resulting in three distinct genetic disorders in humans. These diseases are characterized by neurological phenotypes ranging from intellectual disability to neurodegeneration. Severe ATP7A loss-of-function alleles trigger Menkes disease, a copper deficiency condition where systemic and neurodegenerative phenotypes dominate clinical outcomes. The pathogenesis of these manifestations has been attributed to the hypoactivity of a limited number of copper-dependent enzymes, a hypothesis that we refer as the oligoenzymatic pathogenic hypothesis. This hypothesis, which has dominated the field for 25 years, only explains some systemic Menkes phenotypes. However, we argue that this hypothesis does not fully account for the Menkes neurodegeneration or neurodevelopmental phenotypes. Here, we propose revisions of the oligoenzymatic hypothesis that could illuminate the pathogenesis of Menkes neurodegeneration and neurodevelopmental defects through unsuspected overlap with other neurological conditions including Parkinson's, intellectual disability, and schizophrenia.

OBJECTIVE: Menkes disease (MD) is an X-linked recessive disorder characterized by progressive neuro-degeneration. There are few reports of epilepsy and electroencephalography (EEG) findings and few reports of MD patients in Korea. We explored MD genotypes and phenotypes, including epilepsy, in Korean patients. PATIENTS AND METHODS: All patients diagnosed as MD in our hospital, seven males, were included in this study. Their medical records and EEG findings were reviewed retrospectively. RESULTS: All male patients had developmental delay/regression with hypotonia, and the appearance of their hair and skin was characteristic of MD. A recurrent missense mutation was found in two patients. Two nonsense mutations and one gross deletion were also found. The five male patients with identified molecular defects experienced anticonvulsant-resistant seizures. EEGs in focal seizures usually revealed interictal focal epileptiform discharges over the posterior region without focal slowing. This was followed by modified hypsarrhythmia with less polymorphic background activity in spasms and anteriorly dominant diffuse slowing with generalized and multifocal epileptiform discharges in myoclonic or generalized tonic seizures. Two patients with the same G727R missense mutation both developed seizures that evolved with age but differed in severity. CONCLUSIONS: G727R missense mutation may be relatively common in Korea, as in other countries. There was no clear correlation of genotype with phenotype, even in epilepsy and EEG abnormalities.

BACKGROUND: Epilepsy is a frequent and severe feature of Menkes disease (MD) but only few studies described the long-term evolution of these children. We report a series of 28 epileptic MD patients, with clinical characteristics, EEG abnormalities, brain malformations and long-term outcome. METHODS: EEG, clinical characteristics and neuroimaging features in 28 MD patients were analyzed at the onset of epilepsy and after long-term follow-up (at least 4 years). We subdivided the patients into two groups: Group 1, 16 patients who received a subcutaneous copper-histidine treatment, and Group 2 including 12 patients who did not get any therapies. RESULTS: The large majority of our patients presented at the onset of epilepsy focal seizures (FS) and infantile spasms (IS). Five patients had recurrent status epilepticus (SE). During the follow-up, patients showed multiple seizure types: 6 patients had generalized tonic clonic seizures (GCT), 6 patients presented IS, 10 children had FS, 11 had myoclonic jerks and 3 had SE. Therapy with various antiepileptic drugs had poor efficacy, except in three patients who showed seizure disappearance with consequent discontinuation of antiepileptic therapy. There was no difference of neurological outcome among the two groups analyzed. CONCLUSIONS: Epilepsy in MD is a difficult to treat problem. At the onset, the most frequent type of seizures are FC and IS; in the next months, other kinds of seizures can appear. Many children are drug resistant. Institution of replacement therapy with copper-histidine seems to be not beneficial for epilepsy.

Menkes disease is a lethal multisystemic disorder of copper metabolism characterized by connective tissue abnormalities, progressive neurodegeneration and peculiar "kinky hair." Epilepsy is one of the main clinical features of this disease but it has been described in detail by only a few authors. Most patients develop seizures from 2 to 3 months of age, accompanied by a neurodevelopmental regression. The history of epilepsy is usually characterized by 3 stages: an early stage with focal clonic seizures and status epilepticus, an intermediate stage with infantile spasms, and a late stage with multifocal, myoclonic, and tonic seizures. At the onset, epilepsy can be controlled with anticonvulsant therapy, whereas with the progression of disease, it becomes extremely resistant to all antiepileptic drugs. In this article, we analyze clinical and electroencephalographic (EEG) characteristics of epilepsy in patients with this syndrome.
