Home enteral nutrition does not decrease oral feeding in children during the first year of nutritional support.

BACKGROUND: Enteral nutrition is necessary when nutritional status is poor and oral intake is insufficient or impossible. Although it has been suspected to reduce spontaneous oral feeding, no study has formally assessed the influence of enteral nutrition on pediatric oral intake. The present study aimed to evaluate variation in oral feeding intake after enteral nutrition initiation, and to identify factors influencing oral feeding. METHODS: This retrospective cohort study included 149 pediatric patients from two French tertiary care hospitals, who received home enteral nutrition from 2009 to 2022. The patients were aged 2 months to 17 years (median age 3 years, interquartile range 1.3-9.2). Oral and enteral intakes were assessed when enteral nutrition was initiated (M0), and again at M3 (n = 123), M6 (n = 129), and M12 (n = 134) follow-ups, based on dieticians' and home services' reports. Oral feeding and body mass index z score variations during follow-ups were evaluated using a linear mixed regression model, including "time" as a fixed effect and "patient" as a random effect. Factors associated with oral feeding changes were assessed using a model interaction term. RESULTS: Oral intake did not vary significantly (P = 0.99) over time and accounted for 47.4% ± 27.4%, 46.9% ± 27.4%, 48.4% ± 28.2%, and 46.6% ± 26.9% of the ideal recommended daily allowance (calculated for the ideal weight for height) at M0, M3, M6, and M12, respectively. Delivery method (nasogastric tube versus gastrostomy), prematurity, underlying disease, history of intrauterine growth retardation, and speech therapy intervention did not influence oral intake. Administration (i.e., exclusively continuous nocturnal infusion versus daytime bolus) led to different oral intake development, although oral intake also differed at M0. CONCLUSIONS: Enteral nutrition, although increasing total energy intake, does not alter oral feeding during the first year of administration. Only the mode of administration might influence oral intake.

Pharmacokinetics and safety of fluconazole and micafungin in neonates with systemic candidiasis: a randomized, open-label clinical trial.

AIMS: The pharmacokinetics (PK) of fluconazole and micafungin differ in neonates compared with children and adults. Dosing instructions in product labels appear to be inconsistent with the emerging scientific evidence. Limited information is available on the safety profile of these agents in neonates. Our objective was to study the population PK and safety of both drugs, randomly administered in neonates with suspected or confirmed systemic candidiasis. METHODS: Neonates were randomized 1:1 to fluconazole (loading dose 25 mg kg-1 ; maintenance dose 12 mg kg-1 day-1 or 20 mg kg-1 day-1 , respectively, for infants <30 weeks or ≥30 weeks' corrected gestational age) or micafungin (loading dose 15 mg kg-1 day-1 ; maintenance dose 10 mg kg-1 day-1 ). PK samples were taken on treatment days 1 and 5. Population parameters were determined using NONMEM and Monte Carlo simulations performed to reach predefined targets. Clinical and laboratory data, and adverse events were collected up to 36 weeks' corrected gestational age or hospital discharge. RESULTS: Thirty-six neonates were enrolled. The median (range) gestational age was 28.2 (24.1-40.1) and 26.8 (23.5-40.0) weeks for fluconazole and micafungin, respectively. Based on 163 PK samples, the median population clearance (l h-1 kg-1 ) and volume of distribution (l kg-1 ) for fluconazole were: 0.015 [95% confidence interval (CI) 0.008, 0.039] and 0.913, and for micafungin were: 0.020 (95% CI 0.010, 0.023) and 0.354 (95% CI 0.225, 0.482), respectively. The loading dose was well tolerated. No adverse events associated with micafungin or fluconazole were reported. CONCLUSION: Based on Monte Carlo simulations, a loading dose for fluconazole and dosing higher than recommended for both drugs are required to increase the area under the plasma drug concentration-time curve target attainment rate in neonates.

Micronutrient status of children receiving prolonged enteral nutrition.

BACKGROUND AND AIMS: The aim of this study was to assess the micronutrient status of children receiving prolonged enteral nutrition. METHODS: This cross-sectional single-center study included all 64 children (median age 6.8 years) receiving enteral nutrition providing >50% of daily energy intake for more than 6 months (median duration of enteral nutrition 43 months). The characteristics of the patients and mode of enteral nutrition were recorded. The concentrations of iron, zinc, copper, selenium and vitamins A, D, E and C were measured in plasma. RESULTS: Twelve children (19%) had iron deficiency. A high 25-hydroxyvitamin D concentration was recorded in 20% of the children, but none had associated hypercalcemia. Fifty-two children (81%) had low zinc concentrations in both plasma and erythrocytes. Plasma zinc, calcium, phosphorus and vitamin D concentrations were significantly lower in children receiving fiber supplementation. Abnormal micronutrient concentrations were found more frequently in the children receiving fiber supplementation. No other predisposing factors were associated with micronutrient deficiencies. CONCLUSION: Long-term enteral nutrition can lead to micronutrient deficiencies in children, whose micronutrient concentrations may require regular checking. Fiber supplementation might reduce the bioavailability of zinc, calcium, phosphorus and vitamin D.

[Pyoderma gangrenosum with lung involvement treated with infliximab]. / Pyoderma gangrenosum avec localisations pulmonaires traité par infliximab.

BACKGROUND: Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis often associated with systemic diseases, particularly chronic inflammatory bowel diseases. Extracutaneous manifestations (articular, ocular, renal, pulmonary, hepatosplenic, muscular) exist, with lung involvement being the most common. PATIENT AND METHODS: We report a case of PG with skin and lung involvements in a patient treated with high-dose corticosteroids in a setting of severe ulcerative colitis (UC). Lung involvement was diagnosed during the pretreatment assessment performed prior to initiation of anti-TNFα therapy. Infliximab resulted in rapid improvement of the lung and skin lesions. DISCUSSION: In the event of simultaneous cutaneous PG lesions and lung lesions suggestive of abscess, visceral involvement should be suspected. First-line treatment consists of oral corticosteroids. In our patient, the occurrence of lesions under corticosteroids in UC militated in favour of anti-TNFα therapy, which proved effective.

[Outcome of children with repaired oesophageal atresia]. / Atrésie de l'oesophage : devenir des enfants opérés.

Although initial prognosis of oesophageal atresia is nowadays excellent with more than 95% of survival, the long-term complications are frequent. A gastro-oesophageal reflux is found in 26 to 75% of the cases, responsible for peptic oesophagitis, anastomotic stenosis and Barrett's oesophagus, risk factor of adenocarcinoma of the oesophagus. A dysphagia is frequently observed on these patients, sometimes several years after the surgery, observed in almost 45% of five-year-old children. Growth retardation is found in nearly a third of these children. Respiratory symptoms are particularly frequent, especially in the first years, associating tracheomalacia facilitating the bronchopulmonary infectious episodes (found in about 30% of 5-year-old children). Esotracheal fistula recurrence is very rare. A deformation of the rib cage is reported in 20%, and a scoliosis in 10% of the patients. However, the quality of life of these patients in the adulthood is good, and influenced by the existence of associated malformations. Even if the current prognosis of oesophageal atresia is good altogether, the frequency of the complications (digestive, respiratory, nutritional, orthopaedic) far from the initial intervention, and the necessity of a surveillance of the secondary oesophageal damages, justifies a systematic and multidisciplinary follow-up until adulthood.

Long-term outcome of colon interposition after esophagectomy in children.

BACKGROUND AND OBJECTIVES: Tissues derived from the colon, stomach, and jejunum have been used to replace the esophagus in childhood to cure esophageal atresia or stricture secondary to gastroesophageal reflux or the ingestion of corrosive agents. The outcome in adulthood of colon interposition performed at an early age has yet to be satisfactorily assessed. The aim of this single-center retrospective study was to evaluate the long-term nutritional, digestive, and respiratory outcome of all patients (n = 32) who underwent colon interposition during childhood in our hospital (1970-2001). PATIENTS AND METHODS: Medical records of these subjects were reviewed and their nutritional (weight, height, 24-hour food diary), digestive (questionnaire), and pulmonary function status evaluated. RESULTS: Of the patients, 17 had esophageal atresia (7 males, median age at surgery 11 months, range 0.5-61) and 15 had ingested corrosive substances (10 males, median age at surgery 50 months, range 22-113). Complications occurred less than 1 year postoperatively in 53% and long-term complications (occurring >1 year after surgery) in 84%. Long-term complications were common: digestive symptoms were found in 85% (most frequently observed during the first 5 years of follow-up), abnormal lung function in 7 (58%) of those tested (n = 12), feeding difficulties in 50%, scoliosis in 35%, and nutritional complications in 25%. CONCLUSIONS: Our study showed a high rate of sequelae following esophageal replacement. This highlights the need for multidisciplinary long-term follow-up into adulthood, and research into alternatives to colon interposition as treatment for esophageal strictures.

[Neonatal management of a child exposed to tobacco smoke in utero]. / Prise en charge néonatale d'un enfant exposé in utero au tabac.

The gravidic toxicity of the nicotinism on the fetus is now established. Certain long-term effects related to some substances, including certain unquestionable carcinogens, still remain to be evaluated. The risk of preterm birth is increased and the incidence of the intra-uterine growth retardation is high. Behavioral and physiological disorders, in particular metabolic, cardiac and respiratory disorders are observed from the first day of life. The risk of oro-facial malformations is not excluded. At mid-term the number of ORL and respiratory complications is higher and the risk of sudden infant death is almost doubled. The neonatale period should be used to assess the state of the newborn and to renew recommendations and advice for prevention. Breast feeding should and encouraged. This assessment also gives the mother an additional opportunity to reduce, to even cease smoking. A specialized consultation can be proposed if needed.

Cutaneous disease and drug reactions in HIV infection.

BACKGROUND: Skin diseases, including adverse reactions to drugs, are thought to be more common among patients with human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS) than among other persons. These skin conditions can be disabling or disfiguring and may require discontinuation of essential drugs. METHODS: We identified 684 HIV-infected members of a 265,000-member health maintenance organization and reviewed their medical records to determine the frequency of dermatologic diagnoses from April 1, 1988, through January 15, 1991. We compared the rates of visits per year for skin conditions by HIV-infected men, 20 to 49 years of age, with those by non-HIV-infected men. We used an automated prescription data base to quantify exposures to drugs. RESULTS: Of the 684 HIV-infected patients, 540 (79 percent) were given one or more dermatologic diagnoses, for a total of 2281 diagnoses, including 188 cutaneous reactions to drugs. There were 43 hospitalizations for cellulitis (n = 15), cutaneous drug reactions (n = 13), or other skin problems. As compared with non-HIV-infected men, the men with AIDS had visit rates that were at least 5 times higher for 18 of the 20 most common infectious and inflammatory skin conditions and at least 15 times higher for 9 conditions. Drugs with the highest rate of cutaneous reactions (per 1000 courses) included trimethoprim-sulfamethoxazole (149), sulfadiazine (200), trimethoprim-dapsone (156), and aminopenicillins (93). The number of diagnoses of skin conditions increased according to the stage of disease: it was lowest in patients immediately before the documentation of HIV infection and highest in patients with a diagnosis of AIDS. CONCLUSIONS: Cutaneous diseases, including drug reactions, are extremely common in patients with HIV infection, and their incidence increases as immune function deteriorates.

Contact allergy to corticosteroids: a frequently missed diagnosis?

Contact allergy to corticosteroids is more prevalent than previously recognized and often goes undetected. Nineteen patients with corticosteroid contact allergy are presented. Sixteen reacted to tixocortol pivalate and also to other corticosteroids, particularly to hydrocortisone, which could explain exacerbations of eczema in these cases. Tixocortol pivalate may be a useful marker for screening patients for contact sensitivity to several corticosteroids.

Identification of cross-reaction patterns in allergic contact dermatitis from topical corticosteroids.

Contact allergy to topical corticosteroids occurs more frequently than previously supposed. Cross-allergic phenomena are common. On the basis of a review of the literature and our own patch test data on 15 patients, we conclude that positive patchtests to corticosteroids occur approximately six to seven times more frequently in well-defined groups of structurally-related substances than between corticosteroids of different groups. An analogous substitution pattern on the steroid D-ring or the carbon side chain (C20, C21) seems to have a significant influence on the association of positive patchtest results. This is not the case for other structural variables, such as the presence of a double bond in the steroid A-ring or fluoride substitutions on the B-ring. The effect of other factors such as concomitant sensitization and steroid metabolism in the skin on the development of a corticosteroid polyallergy are analysed, and the specificity and sensitivity of cross-allergy phenomena are evaluated. These are important in the selection of a topical steroid in the future treatment of a corticosteroid sensitive patient.

Silver polish: another source of contact dermatitis reactions to thiourea.

A cleaning woman in a restaurant became sensitized to thiourea in a silver polish. The dermatitis persisted for several months and occasionally flared up after exposure to sunlight, even after she no longer used the product. Patch testing and photopatch testing showed that she had both contact and photocontact allergy.

Physicochemical studies on bovine eye lens proteins. II. Comparative physical study of the low-molecular-weight alpha-crystallins from calf lens cortical and nuclear fiber cells.

The alpha L of cortical and nuclear fiber cells have been studied using hydrodynamical and physicochemical techniques. From the sedimentation and the diffusion coefficients in identical conditions, it can be concluded that alpha L,N is appreciably larger than alpha L,C but both have a similar structure in solution: a spherical particle with a high hydration. The alpha L,N not only contains several degraded alpha A- and alpha B-peptides but also a typical pattern of beta-peptides. The fluorescence spectrum indicates a shift of the hydrophobic tryptophan residues from a hydrophobic environment in alpha L,C to a more solvent-exposed and polar neighbourhood for alpha L,N. Also solubility studies on alpha L,C and alpha L,N in different solvent conditions and temperatures, indicate more apolar interactions between the peptides of the nuclear alpha L, than its cortical counterpart. The more hydrophobic interaction pattern of the peptides in alpha L,N can also be reconciled with a lower mean hydration potential, indicative of a higher hydrophobicity of the degraded alpha A-peptides.
