Health-related quality of life of food-allergic children compared with healthy controls and other diseases

BACKGROUND

Food allergy is a potentially life-threatening disease, affecting up to 10% of the pediatric population.

OBJECTIVE

The aim of our study was to assess the health-related quality of life (HRQL) of food-allergic patients compared with the general population and patients with other chronic diseases with dietary or allergic burden, in a cross-sectional study.

METHODS

We recruited patients aged 8-17 years diagnosed with food allergy and matched healthy controls recruited in schools. We also included patients with asthma, inflammatory bowel disease, celiac disease, diabetes, obesity, and eating disorders. We used the CHQ-CF87 questionnaire for generic HRQL assessment. Food allergy HRQL was also assessed using specific questionnaires: Food Allergy Quality of Life Questionnaire (FAQLQ) and Food Allergy Independent Measure (FAIM).

RESULTS

One hundred and thirty-five food-allergic children, 255 children with chronic diseases, and 463 healthy controls were included in the analyses. Food-allergic patients had a better HRQL than healthy controls in the Behavior (BE), Bodily Pain (BP), Family Activities (FA), and Mental Health (MH) domains and a worse HRQL in the General Health Perception (GH) domain (p = .048). Food-allergic patients exhibited a better HRQL than patients affected by other chronic diseases, notably diabetes. Although an epinephrine autoinjector had been prescribed to 87.4% of the food-allergic children, only 54.2% of them carried it at all times.

CONCLUSION

Food-allergic patients display overall good HRQL compared with the general population and those with other diseases with daily symptoms and treatments, in line with recent improvements in food allergy management.

Variation of carbohydrate intake in diabetic children on carbohydrate counting

AIMS

Carbohydrate counting (CC) is a technique for managing diabetes particularly based on the counting of carbohydrates. It allows diabetic patients to vary their amount of carbohydrates from one meal to another by adjusting their insulin dose. The primary objective was to determine the variation of carbohydrate intake (CI) in children on CC.

METHOD

This was a prospective study conducted between 2014 and 2016. We collected the amount of carbohydrates eaten at each meal by 77 diabetic over a period of 28 days (i.e. 8068 data). We analyzed the number and percentage of significant CI variation rates from one day to another, both for the whole day and for each meal. The CI variation rate was deemed significant if it was greater than or equal to 30%.

RESULTS

The percentage of significant CI variation rates was 30% at the daily level, 34% for breakfast, 44% for lunch and dinner, and 53% for snack. The percentage of significant variation rates varied according to age, treatment and occurrence of events.

CONCLUSION

Children varied their CI significantly from one meal to another more than one in three times. CC offers flexibility and a better quality of life for children using this method.

Sleep disordered breathing in patients with Prader-Willi syndrome: A multicenter study

OBJECTIVES

Sleep disordered breathing (SDB) is common in patients with Prader-Willi syndrome (PWS) and systematic screening is recommended, especially before growth hormone treatment. The aim of the study was to describe the baseline SDB and therapeutic interventions in a large cohort of patients.

STUDY DESIGN

Retrospective study.

SUBJECT SELECTION

Eighty-eight patients with PWS, median [interquartile range] age of 5.1 [1.0-14.5] years old (range 0.3-44.3), who were followed in three centers (France, Italy).

METHODOLOGY

Anthropometrics, polygraphy (PG), and gas exchange data were analyzed.

RESULTS

Median body mass index (BMI) was 20 [16-34] kg/m(2), BMI z-score for patients aged 2-20 years old was 2.1 [1.2-2.8] SD, mixed-obstructive apnea-hypopnea index (MOAHI) 1.8 [0.6-5.0] events/hr, and central apnea index (CAI) 0.1 [0.0-0.6] events/hr. Minimum pulse oximetry (SpO2) was 88 [84-91]%, percentage of time with SpO2 <90% 0.1 [0.0-1.0]%, and oxygen desaturation index 2 [1-4]/hr. An apnea-hypopnea index (AHI) ≥ 1.5 and ≥ 5 events/hr was observed in 53% of children and 41% of adults, respectively. No correlations were observed between MOAHI and anthropometrics data (age, BMI, BMI z-score), while MOAHI significantly correlated with SpO2 indexes. Age and BMI only weakly correlated with SpO2 indexes. Growth hormone could be initiated in 48 patients. Regarding post-PG therapy, 9 patients had upper airway surgery, and noninvasive CPAP/bilevel ventilation was started in 16 patients.

CONCLUSIONS

Patients with PWS exhibit a high prevalence of SDB. The lack of association between obesity and SDB leads to hypothesize that hypotonia and/or facial dysmorphic features may play a major role in the occurrence of SDB.

Impaired sexual and reproductive outcomes in women with classical forms of congenital adrenal hyperplasia

OBJECTIVES

The objectives of the study were 2-fold: 1) a detailed description of sexual and reproductive outcomes in adult women with congenital adrenal hyperplasia (CAH) of different phenotypic severity at birth; and 2) comparisons of these outcomes among CAH subtypes and between CAH women and non-CAH control women.

DESIGN

This was a cross-sectional study using a face-to-face interview, a written questionnaire, the Female Sexual Function Index, and a gynecological examination.

PATIENTS

Patients included 35 women with CAH, representing Prader stages I-V at birth, aged 18-43 yr, who had been treated from birth to adolescence in the same pediatric endocrine clinics. Sixty-nine non-CAH healthy control women were selected from hospital-staff families.

RESULTS

None of the CAH women expressed doubts about their gender assignment. Twenty percent (seven of 35) had homosexual inclinations; 23% (eight of 35) were married; three reported a complete lack of sexual activity; and 37% (13 of 35) said they never had heterosexual intercourse with vaginal penetration. Sexual functioning as assessed by the Female Sexual Function Index was much lower in CAH women than controls and lowest in CAH women with high Prader stages. Eighty-one percent (18 of 22) experienced pain during vaginal penetration. Only eight women became pregnant, and 17% (six of 35) had children.

CONCLUSIONS

Despite expert medical and surgical care by physicians dedicated to this rare disease, women with CAH still suffer major limitations in their sexual function and reproductive life.

[Comparative study of fixation mode in total knee arthroplasty with preservation of the posterior cruciate ligament]

PURPOSE OF THE STUDY

We performed a prospective randomized study to compare two fixation modes, with and without cement, for total knee arthroplasty.

MATERIAL AND METHODS

The study series was composed of 96 cemented or noncemented total knee arthroplasties performed between May 1993 and October 1995. The only difference was the diamond interface used for cemented prostheses and the mesh interface used for uncemented prostheses. The operator was unaware of the type of fixation until the bone slices had been obtained. We assessed outcome in 73 cases with a mean follow-up of 27 months. The two populations were comparable for preoperative clinical status, bone tophicity and surgical procedure.

RESULTS

The mean duration of the operation was sgnificantly longer (> 10 min) for the cemented protheses. The complication rates were comparable but we did have two mobilizations of the tibial implant in the noncemented group. The total scores (127 +/- 29 in the cemented group versus 135 +/- 20 in the uncemented group) were significantly different. There were however more cases with degradation of the controlateral knee in the cemented group although the difference was not significant. When these cases were excluded from the analysis, the total scores for two groups were similar (143 and 140 respectively). Radiographic outcome was quite different with mobilization of the tibial implant in 2 cases and the rate of lucent borders was significantly higher in the noncemented group.

DISCUSSION AND CONCLUSION

While the clinical outcome was comparable, the quality of the fixation was significantly better with cemented arthroplasty, which remains the gold standard.

Treatment of Madelung's deformity by lengthening and reaxation of the distal extremity of the radius by Ilizarov's technique

Madelung's deformity was first described in 1878. It is characterised by a typical deformity of the carpus and not only causes pain but also impedes mobility and aesthetic appearance. Surgical correction can be effected during adolescence, the most frequently employed technique being conical osteotomy. We present a novel technique of lengthening and aligning the distal radial extremity using Ilizarov's technique. Five carpal joints were operated on in three 13-year old girls. An aesthetic effect was obvious in all the cases. Mobility improved by 30 degrees in the direction of the extension and pain always subsided directly after surgery.
