Abstract
Constitutional MisMatch Repair Deficiency (CMMRD) is caused by homozygous or compound heterozygous germline variants in one of the mismatch repair (MMR) genes (MSH2, MSH6, PMS2, MLH1). This syndrome results in early onset colorectal cancer, leukemia and lymphoma, brain tumors and other malignancies. Children with CMMRD are at high risk of developing multiple cancers and cancer surveillance does not guarantee detection of cancer at a curable stage. The development of a preventive treatment strategy would be a major step forward. Long-term daily use of acetylsalicylic acid (ASA) has been shown to reduce cancer risk in individuals with Lynch syndrome (LS). LS is caused by heterozygous germline variants of MSH2, MSH6, PMS2 and MLH1 and characterized by an increased risk of developing colorectal and endometrial cancer at adult age. Here we discuss the potential use of ASA for cancer prevention in patients with CMMRD.

Dihydrolipoamide dehydrogenase deficiency: a still overlooked cause of recurrent acute liver failure and Reye-like syndrome. Mol Genet Metab 2013; 109:28-32. [PMID: 23478190 DOI: 10.1016/j.ymgme.2013.01.017] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2012] [Revised: 01/26/2013] [Accepted: 01/26/2013] [Indexed: 10/27/2022]
Abstract
The causes of Reye-like syndrome are not completely understood. Dihydrolipoamide dehydrogenase (DLD or E3) deficiency is a rare metabolic disorder causing neurological or liver impairment. Specific changes in the levels of urinary and plasma metabolites are the hallmark of the classical form of the disease. Here, we report a consanguineous family of Algerian origin with DLD deficiency presenting without suggestive clinical laboratory and anatomopathological findings. Two children died at birth from hepatic failure and three currently adult siblings had recurrent episodes of hepatic cytolysis associated with liver failure or Reye-like syndrome from infancy. Biochemical investigation (lactate, pyruvate, aminoacids in plasma, organic acids in urine) was normal. Histologic examination of liver and muscle showed mild lipid inclusions that were only visible by electron microscopy. The diagnosis of DLD deficiency was possible only after genome-wide linkage analysis, confirmed by a homozygous mutation (p.G229C) in the DLD gene, previously reported in patients with the same geographic origin. DLD and pyruvate dehydrogenase activities were respectively reduced to 25% and 70% in skin fibroblasts of patients and were unresponsive to riboflavin supplementation. In conclusion, this observation clearly supports the view that DLD deficiency should be considered in patients with Reye-like syndrome or liver failure even in the absence of suggestive biochemical findings, with the p.G229C mutation screening as a valuable test in the Arab patients because of its high frequency. It also highlights the usefulness of genome-wide linkage analysis for decisive diagnosis advance in inherited metabolic disorders.

Abstract
We describe a fatal case of Reye's syndrome in a 12-year-old male patient during an influenza A (H3N2) infection for which he received salicylates. In the current situation of the novel A/H1N1 virus pandemic, we believe that it is of high importance to emphasize the risks associated with salicylate intake to avoid the reappearance of Reye's syndrome.

Liver pathology in Malawian children with fatal encephalopathy. Hum Pathol 2011; 42:1230-9.

Abstract
A common clinical presentation of Plasmodium falciparum is parasitemia, complicated by an encephalopathy for which other explanations cannot be found, termed cerebral malaria-an important cause of death in young children in endemic areas. Our objective was to study hepatic histopathology in Malawian children with fatal encephalopathy, with and without P falciparum parasitemia, to assess the contributions of severe malaria. We report autopsy results from a series of 87 Malawian children who died between 1996 and 2008. Among 75 cases with P falciparum parasitemia, 51 had intracerebral sequestered parasites, whereas 24 without sequestered parasites had other causes of death revealed by autopsy including 4 patients with clinicopathologic findings which may represent Reye syndrome. Hepatic histology in parasitemic cases revealed very limited sequestration of parasites in hepatic sinusoids, even in cases with extensive sequestration elsewhere, but increased numbers of hemozoin-laden Kupffer cells were invariably present with a strong association with histologic evidence of cerebral malaria by quantitative analysis. Of 12 patients who were consistently aparasitemic during their fatal illness, 5 had clinicopathologic findings which may represent Reye syndrome. Hepatic sequestration of parasitized erythrocytes is not a feature of fatal malaria in Malawian children, and there is no structural damage in the liver. Reye syndrome may be an important cause of fatal encephalopathy in children in Malawi with and without peripheral parasitemia and warrants close scrutiny of aspirin use in malaria-endemic areas.

Abstract
PURPOSE To analyse antipyretics (APs) prescriptions profile in children, particularly the frequency of AP combinations. METHODS APs (acetylsalicylic acid, paracetamol, ibuprofen or ketoprofen) prescribed to children below 12 years and refunded by a public health insurer in 2003, throughout France, were examined. RESULTS A total of 513 034 prescriptions were refunded for 240 720 children. The mean number of AP prescriptions per child was the highest in children aged 6 months to 2 years. Paracetamol was the main AP prescribed, but its prescription declined with age, from 90.8% below 3 months old to 57.4% between 6 and 12 years old. Ibuprofen-only prescriptions were rare below 3 months and maximal between 2 and 6 years. The ibuprofen/paracetamol combination was prescribed from 6 months old, and its frequency was maximal between 2 and 6 years old (21.7%). CONCLUSIONS The clear predominance of paracetamol prescriptions suggests that French prescribers are relatively aware of the relative risk-benefit ratio of the different APs. Studies are required to determine if the APs are prescribed to be used alternately or when a monotherapy fails. Guidelines to manage fever in children are needed in France to restrict APs combination to the case of paracetamol failure.

Abstract
Reye syndrome is an extremely rare but severe and often fatal disease. Death occurs in about 30-40% of cases from brainstem dysfunction. The disease typically is preceded by a viral infection with an intermediate disease-free interval of 3-5 days. The biochemical explanation for Reye-like symptoms is a generalized disturbance in mitochondrial metabolism, eventually resulting in metabolic failure in the liver and other tissues. The etiology of 'classical' Reye syndrome is unknown. Hypothetically, the syndrome may result from an unusual response to the preceding viral infection, which is determined by host genetic factors but can be modified by a variety of exogenous agents. Thus, several infections and diseases might present clinically with Reye-like symptoms. Exogenous agents involve a number of toxins, drugs (including aspirin [acetylsalicylic acid]), and other chemicals. The 'rise and fall' in the incidence of Reye syndrome is still poorly understood and unexplained. With a few exceptions, there were probably no new Reye-like diseases reported during the last 10 years that could not be explained by an inherited disorder of metabolism or a misdiagnosis. This may reflect scientific progress in the better understanding of cellular and molecular dysfunctions as disease-determining factors. Alternatively, the immune response to and the virulence of a virus might have changed by alteration of its genetic code. The suggestion of a defined cause-effect relationship between aspirin intake and Reye syndrome in children is not supported by sufficient facts. Clearly, no drug treatment is without side effects. Thus, a balanced view of whether treatment with a certain drug is justified in terms of the benefit/risk ratio is always necessary. Aspirin is no exception.

Abstract
Reduced level of consciousness is a common clinical finding in acutely sick patients. In the majority of cases a cause for the encephalopathy is readily identifiable,whilst in a minority the aetiology is more difficult to ascertain. Frequently the onset of encephalopathy is associated with, or follows, infection. The mechanisms through which infection leads to encephalopathy are diverse. They range from direct microbial invasion of the brain or its supporting structures, to remote, infection-triggered mechanisms such as acute disseminated encephalomyelitis. Most common however, is the encephalopathy caused through a remote effect of systemic sepsis-septic encephalopathy. This article discusses the clinical presentation and underlying pathogeneses of the acute encephalopathies associated with infection, aiming to aid both their recognition and treatment.

Abstract
BACKGROUND Indication-based, in comparison to diagnoses-based, drug utilization studies in children are scarce in the literature. AIM To determine the adequacy of the prescriber's indications for specific drug treatments compared to the current literature in five different European countries; and to show the possibilities of performing indication-based drug utilization studies. DESIGN a descriptive, cross-sectional, international study. PATIENTS AND METHODS Randomly selected sample of 12,264 paediatric outpatients seen in consultation rooms attended by paediatricians or general practitioners. Data on patient demographics, diagnoses, and pharmacological treatment, with therapeutic indications for each drug, were collected in pre-designed forms. Diagnoses and indications were coded using the ICD-9 and drugs according to the ATC classifications. RESULTS Indications were registered for every drug prescribed in all locations. Antibiotic indications considered incorrect (common cold, upper respiratory tract infections, viral infections, general symptoms or "not specified") accounted from 24.1% of the total antibiotics prescribed in Tenerife to 67.4% in Slovakia. Incorrect indication of first-choice antibiotics prescribed in acute otitis media and tonsillitis ranged from 28.9% of total antibiotics use in Russia to 75.4% in Tenerife. Correct antibiotic indications ranged from 23.4% of total antibiotics used in Slovakia to 65.7% in Tenerife. Aspirin use in febrile viral conditions was detected mainly in Toulouse and Russia. CONCLUSION The main areas for improvement detected were high use of mucolytics, prescription of aspirin in potential or established viral infections, overuse of antibiotics and identification of specific patterns of incorrect antibiotic prescription and clinical entities associated with each location.

Abstract
BACKGROUND Varicella, an almost compulsory affection in children, is complicated in 2% of cases. Some treatments such as powders and non-steroidial anti-inflammatories (NSAIs) may favorise or worsen infectious complications. OBJECTIVE To assess out-patient prescriptions in children presenting with varicella. METHODS Three methods were used. Collection of the out-patient prescriptions in children (n=122) subsequently presenting with varicella in one of the hospitals in the North of France conducted from January to May 2003. A telephone survey was made among 50 general practitioners in the same area in March 2003. This collected not only the prescription of the last case reported, but also the intended prescriptions when confronted with a simulated case of the disease. RESULTS Powders were prescribed in 44 to 54% of cases, NSAIs in 14 to 16%, aspirin in 2 to 4%, and oral acyclovir in 4%. The three assessment methods did not reveal any differences in the prescription of antibiotics, more frequent in the children subsequently visiting the hospital (25 vs. 6%), and the prescriptions of paracetamol. Only 38% of the prescriptions during clinical cases corresponded to the guidelines. CONCLUSION It is crucial that practitioners be informed on the treatment of varicella and the risks of severe cutaneous surinfections enhanced by certain prescriptions.

Abstract
NSAIDs are one of most frequently prescribed agents in clinical practice. Whereas hepatotoxicity is a rare complication of most NSAIDs (typically 1 to 10 per 100,000 persons exposed), the high level of usage means that these drugs cause liver disease. Because of their divergent chemical structures, the mechanisms and clinicopathological manifestations of hepatotoxicity vary widely. The reactive metabolite syndrome, in which serious rash, eosinophilia, and other forms of tissue injury are common, may be incited by several NSAIDs, including newer agents. Women, people aged more than 50 years, and for some drugs, the type of arthritis, may be risk factors for drug-induced liver injury. The spectrum of NSAID-drug related hepatotoxicity continues to expand, with reports of interactive toxicity in adults with hepatitis C and recognition of rare cases of liver disease associated with non-selective, selective, and preferential COX-2 inhibitors. Better outcomes require people taking NSAIDs to be aware of possible drug reactions involving the liver, and prescribers should be vigilant for early symptoms of hepatotoxicity so that incriminated agents are discontinued promptly.

Abstract
UNLABELLED Idiopathic Reye syndrome is a rare disease revealed by unexplained encephalopathy and microvesicular liver steatosis. Some clinical and epidemiological studies mainly performed in English speaking countries questioned the reality of Reye syndrome because numerous know inherited metabolic diseases, and some of them unrecognized, could mimick this disorder. We focused in our study on severe forms of Reye syndrome admitted to a pediatric intensive care unit. METHODS Retrospective study over the last eleven years (1991-2001) included all the pediatric patients admitted to our tertiary referral center with the classical American Reye syndrome criteria (e.g. CDC). Extensive metabolic screening was performed in all cases, except for the ultimately dead patients. RESULT Fourteen patients (mean age 52 months) were included. Fever always occurred before their admission and aspirin (n = 12) or acetaminophen (n = 7) was prescribed. Median Glasgow scale was 7 on admission. Mean amoniac plasma level was 320 mumol/L and alanine-aminotransferase peak plasma level 1475 +/- 1387 IU/L. Mechanical ventilation was started in ten children and six of them underwent continuous venovenous hemofiltration. Three patients ultimately died and 11 survived with a mean five years follow-up without relapses or neurological impairment. Any of them demonstrated inherited metabolic disease except for one infant with hereditary fructose intolerance. CONCLUSION Unlike widespread opinion, severe Reye syndrome without identified metabolic disorders seems to not disappear in our country. Reye syndrome remains a potentially life threatening disease and raises for aggressive treatment of brain edema. If aspirin and Reye syndrome association are not formally documented in France, cautiousness must be kept in mind and all the aspirin adverse effects notifications should be addressed to the public drugs survey network.
