RESUMEN
BACKGROUND AND OBJECTIVE: Even though patients with cystic fibrosis (CF) are continuously improving their life expectancy, guidelines for transition to adult services have not been clearly determined yet. The aim of this study was to analyze the management of this transition in the CF care center of Angers, France. PATIENTS AND METHOD: From their medical files, we analyzed the transfer of 22 patients with CF from pediatric to adult care. The perceptions of patients and caregivers regarding this transition were evaluated using anonymous questionnaires. RESULTS: The initial objective was to transfer patients around 18 years of age, offering them 3 or 4 joint consultations with a pediatrician and adult lung specialist. The median age of transfer was 22 years and the median duration of the transition period was 9 months. Half of the patients had only 1 joint transfer consultation during transition. The patient reaching the age of 18 and maturity were the most common criteria mentioned for transfer. All highlighted problems leaving the pediatric team they had grown attached to and its familiar environment. Caregivers described the transfer as a success, whereas half of the patients were dissatisfied with it, with both patients and caregivers indicating that the transition was too short without enough joint consultations. CONCLUSIONS: This study shows that this period is a major life event for the patient with CF. The transition process must be organized with the patient and independent behaviors should be encouraged. Adult and pediatric teams need to cooperate. Based on this experience and former medical data, we suggest a transition program for patients with CF.

A high prevalence of low bone mineralization is documented in adult patients with cystic fibrosis (CF). Osteopenia is present in as much as 85% of adult patients and osteoporosis in 13 to 57% of them. In children, studies are discordant probably because of different control database. Denutrition, inflammation, vitamin D and vitamin K deficiency, altered sex hormone production, glucocorticoid therapy, and physical inactivity are well known risk factors for poor bone health. Puberty is a critical period and requires a careful follow-up for an optimal bone peak mass. This review is a consensus statement established by the national working group of the French Federation of CF Centers to develop practice guidelines for optimizing bone health in patients with CF. Recommendations for screening and for calcium, vitamin D and K supplementation are given. Further work is needed to define indications for treatment with biphosphonates and anabolic agents.

Newborn screening (NBS) of cystic fibrosis (CF) was implemented throughout the whole of France in 2002, but it had been established earlier in three western French regions. It can reveal atypical CF with one or two known CFTR mild mutations, with an uncertain evolution. The sweat test can be normal or borderline. In Brittany, from 1989 to 2004, 196 CF cases were diagnosed (1/2885 births). The incidence of atypical CF diagnosed by NBS is 9.7% (19 from 196). The outcome of 17 (2 lost of view) has been studied, with 9 other atypical CF cases diagnosed by NBS in two other regions. The follow-up period extends from 0.25 to 19.8 years (NBS implemented in Normandy in 1980) with mean age 4.6 years. The most frequent mild mutation is R117H ISV8-7T (50%). At the time of the last visit, nutritional status is normal. All these CF patients are pancreatic sufficient. Only one patient exhibits respiratory infections, whereas 7 others have them intermittently. Two of them had intermittent Pseudomonas aeruginosa colonization at 2.8 and 6.5 years. Mean Shwachman score is 96.7, mean Brasfield score is 22.8. Eight children have had lung function tests (mean follow-up of 10 years): mean FVC was 99% of predicted, mean FEV1 101%, but one of them has FEV1 of 48%. Predicting the phenotype of these atypical CF patients remains difficult, thus complicating any genetic counselling. A regular clinical evaluation is necessary, if possible by a CF unit, because CF symptoms may appear later.

OBJECTIVES: Little information is available to incoming students in pediatrics residency programs on the experiences of past residents. The objective of this study was to investigate the pediatrics training programs and determine the professional outcomes of graduating residents between 1990 and 2000 in the Western Interregion. POPULATION AND METHODS: Questionnaires were distributed to the 187 medical students enrolled in pediatrics residency programs between 1990 and 2000 in the six university hospital centers of the Western Interregion. The questions concerned the details of training, the modes of residency positions, and current professional and personal situations. One hundred and sixty-five (88%) individuals responded. RESULTS: Seventy-seven percent of the practicing pediatricians stated that the training they had received during residency was adapted to their current practice. This percentage was higher for hospital staff physicians (82%) than for the physicians in private practice (50%) or those with salaried positions outside the hospital system (58%). One hundred and twenty-four had either completed post-residency training (97) or were doing so (27) at the time of the survey. All but one were professionally active, three quarters of them in hospitals and, of these, most were in the hospitals where they had trained. Eighty-six percent of the practicing pediatricians said they were satisfied with their professional work and 73% said they were satisfied with their personal lives. CONCLUSION: These results support the current reflection on reforming the residency training program in pediatrics, especially with regard to its prolongation and the diversification of the training options to take into account the individual student's professional orientation.

We underline the clinical importance of a specific eating disorder in 3 to 10 years old children, when the majority of the works about the prepubertal eating disorders focus either on the period just preceding adolescence (often between 10 and 13 years), or on the second half of the first year of the baby. Within the eating disorders described in the literature, we compare the clinical presentation of most of these 3 to 10 years old children with the food avoidance emotional disorder described during adolescence. These problems of eating behaviour (various selective eating with or without provoked vomiting) are ignored for a long time in these young children because of quite a satisfactory growth, but these children are often seen in emergency rooms because of a brutally complete eating refusal. Therapeutic consultations allow these children to express their fears about diseases, poisoning and death, for themselves or for their close relations, in particular the mother, without endangering their body. The early recognition and care of these difficulties of conciliation between the body and the thoughts impose a narrow collaboration between paediatric and psychiatric staffs.

UNLABELLED: Some immune system abnormalities have been reported in cystic fibrosis, particularly the presence of antineutrophil cytoplasmic antibodies (ANCAs). The purpose of this study was to determine the frequency of these antibodies in a population of patients with cystic fibrosis and to assess their relationship with the disease progression. POPULATION AND METHODS: This retrospective study looked for the presence of these antibodies in sera from 64 patients (30 boys and 34 girls) aged one to 29 years. All patients were followed up within the Cystic Fibrosis Center of the University Hospital of Angers. The serum samples were collected in 2001 during the yearly check-up to evaluate disease status. RESULTS: Seven of the 64 patients presented the antibodies. Univariate analysis showed that these patients were significantly older and more often chronically infected with Pseudomonas aeruginosa than the other patients. They also scored significantly more poorly on pulmonary radiography and showed significantly higher IgG and CRP. Multivariate analysis revealed that the two following independent factors were associated with the presence of ANCAs: chronic P. aeruginosa infection and high IgG level. CONCLUSION: This work confirms the abnormally high frequency of antineutrophil cytoplasmic antibodies in patients with cystic fibrosis. These antibodies were observed in the sickest patients with severe infection status. They reflect the impact of inflammatory processes in the pathogenesis of the disease. Detection of these antibodies might be an indication for intensified treatment of bronchial infections.

AIM: To assess knowledge acquired by adolescents about their inflammatory bowel disease (IBD). METHODS: An anonymous questionnaire was given during consultation to adolescents followed for IBD by pediatricians from 13 hospitals between 1 September 2012 and 1 July 2013. After parental consent, these physicians completed a form at the inclusion of each patient, in which the characteristics of IBD were detailed. The patients mailed back their questionnaire. RESULTS: A total of 124 patients from 12 to 19 years of age were included with a response rate of 82% (all anonymous); 23% of the patients thought that diet was a possible cause of IBD and 22% that one of the targets of their treatment was to cure their disease for good. Of the patients reported having Crohn disease, 46% knew the anoperineal location and 14% knew that Crohn disease can affect the entire digestive tract. Twenty-five percent of the patients were able to name one side effect of azathioprine (88% had already received this treatment), 24% were able to name one side effect of infliximab (54% had already received this treatment), 70% of the adolescents knew that smoking worsens Crohn disease, 68% declared they had learned about their IBD from their pediatrician, and 81% said they would like to receive more information. CONCLUSION: Adolescents with IBD have gaps in their general knowledge and the different treatments of their disease. Their main source of information is their pediatrician, warranting the implementation of customized patient education sessions.

BACKGROUND: The aim of this study was to assess the bone mineral density of cystic fibrosis patients. PATIENTS AND METHODS: We have retrospectively studied 45 patients with cystic fibrosis, 22 females and 23 males, aged between six and 27 years (mean 13 +/- 5.5 years). Nutritional status, Shwachman score, pulmonary function, serum calcium and 25-hydroxyvitamin D levels and lumbar bone mineral density by dual energy X-ray absorptiometry were assessed. RESULTS: The average height of the patients was 97 +/- 4% (range: 86-106) and body mass index 93 +/- 10% (range 77-114) of the normal values of age. The average Shwachman score was 80 +/- 11/100 (range: 47-96). The forced expiratory volume in 1s was 80 +/- 29% (21-128) and the vital capacity 85 +/- 21% (range: 40-122) of the predicted values. The serum levels of calcium and 25-hydroxyvitamin D were lower than normal values in six cases and one case respectively. Thirty-eight patients had a mean lumbar spine bone mineral Z-score which was -1.35 +/- 1.2 DS and 84.7 +/- 13.5% of the normal values. It was correlated with the height, the body mass index, the Shwachman score, the FEV 1 and the vital capacity. CONCLUSION: Decreased bone density is frequent among cystic fibrosis subjects. It shows a lack of control of the illness. It remains unknown with usual investigation; the dual X-ray absorptiometry should, each time it is possible, take part of investigations in those patients.

Villous atrophy in an infant immediately suggests food intolerance. We report a case with an unusual cause. This female infant was first examined at 5 months for anorexia and failure to thrive. Intestinal biopsy showed total villous atrophy. A diet excluding gluten and cow milk proteins failed to improve her condition and the infant was hospitalized at 7 months for further investigations. The infant was hypotonic with a head lag. No other clinical sign was noted. Serum transaminases were increased 5- to 10-fold and CSF proteins concentration was increased. Metabolic investigations revealed hyperlactacidaemia and an increased lactate/pyruvate ratio during fasting and feeding, suggesting a mitochondrial cytopathy. Respiratory chain enzymatic activity measurements confirmed the diagnosis and showed severely decreased activities of complexes I, III and IV in both the liver and muscle. Molecular analysis demonstrated depletion of mitochondrial DNA in the liver (75%) and in muscle (97%). The infant was discharged under continuous enteral nutrition. Improvement was of short duration and the infant died at 1 year of age of massive hepatic failure. This is the first report of a mitochondrial DNA depletion with total villous atrophy and malabsorption as early clinical onset. A mitochondrial cytopathy should be considered in such conditions when food exclusion diets fail.

UNLABELLED: Alarming hemangiomas, due to their site or repercussions, require pharmacological treatment. Corticosteroid therapy is indicated by first intention. In the event of failure, interferon alpha is proposed. CASE REPORTS: Case 1. A five-week-old infant was admitted to hospital for an extensive hemangioma of the left side of the face and neck with necrosis of the upper lip and ear. Prednisolone (2 mg/kg/day) by intravenous route brought about no improvement. Interferon alpha 2a (3 MU/m2/day of Referon by subcutaneous injection) enabled regression of lesions from the sixth month of treatment. After 11 months of treatment, the hemangioma had all but disappeared and interferon therapy was stopped. Repair surgery was planned at 24 months of age. Case 2. A one-month-old infant suffered from a hemangioma of the right side of the face with orbital invasion and risk of amblyopia. Prednisone (2 mg/kg/day) by oral route was ineffective. Interferon alpha 2a enabled regression of the hemangioma and the eye opened from the third month of treatment. Interferon therapy was stopped after 14 months. Initial repair surgery intervention was possible at two years of age. Spastic paraplegia was diagnosed at 18 months of age. The brain and medullar magnetic resonance imaging was normal. No etiology could explain the neurological attack. The possible toxic effect of interferon alpha is discussed. CONCLUSION: Interferon alpha is an effective treatment for hemangiomas. It significantly reduces spontaneous regression time. The uncertainty of long-term effects in infants with hemangiomas incites its indication to be limited to alarming corticosteroid-resistant forms and necessitates prolonged neurological surveillance.

UNLABELLED: Malformative uropathies diagnosed in utero are increasing in number. This work describes the decision strategy adopted in Angers concerning the neonatal handling of those abnormalities. PATIENTS AND METHODS: One hundred children born between 1988 and 1990, with prenatally suspected fetal uropathy, were included in the study and followed for a period of 3 years. In every case, an ultrasound scan was performed at birth. In cases with persistent abnormality, a voiding cystourethrography was done in the first week of life. An intravenous urograph and/or a nuclear renography were performed during the second month of life. RESULTS: Twenty-nine children were normal. Seventy-one were affected by 126 isolated or related uropathies; the most frequent ones were the ureteropelvic junction obstruction syndrome (48), ureterovesical junction obstruction (18) and multicystic kidneys (13). A vesicoureteral reflux was associated in 22% of cases. The diagnosis was perfectly correlated with the prenatal diagnosis in 50% of cases. Fourteen of the normal children had a later ultrasound scan control, between 2 and 9 months; later on, three of them showed a moderate ureteropelvic junction obstruction syndrome. Amongst the 48 ureteropelvic junction obstruction syndromes, 22% have been operated on. The others obstructive uropathies remained stable or spontaneously improved. DISCUSSION: These results require us to discuss as matter of priority the large number of spontaneously regressive prenatal hydronephrosis and the necessity to establish a consensus for the pre and postnatal pathological thresholds of the anteroposterior pelvic diameter, the interest in carrying out a voiding cystography after the birth when dilatation is confirmed, the interest of nuclear renography for the diagnosis and follow-up of obstructive uropathies and the absence of urgency for surgery. CONCLUSION: We propose a decision tree specifying the action to take when facing the diagnosis of a prenatal hydronephrosis. It could be a part of the reflection for the medical teams handling these uropathies is the aim of a consensual attitude which is now essential.

CASE REPORT: A pregnant woman who was a regular user of anxiolytics was admitted to the maternity ward at 38 weeks and 4 days amenorrhea after a massive overdose of clorazepate dipotassium, a benzodiazepine. The exact quantity ingested was undetermined. The infant, born at 39 weeks, presented no spontaneous breathing and tracheal intubation was necessary in the delivery room. The neonatal blood concentrations of the clorazepate metabolites were very high at delivery (26 mg/l nordiazepam and 3.5 mg/l oxazepam) and showed little change over the next 5 days (16 mg/l nordiazepam and 2.1 mg/l oxazepam, with an apparent half-life of 168 h for nordiazepam and 160 h for oxazepam). By day 6, the infant was still dependent on ventilator support and enterodialysis was begun with repeated doses of activated charcoal (1 g/kg every 6 h by gastric tube). Treatment was continued for 5 days and a spectacular diminution in the serum concentrations of the two metabolites was noted on day 11: 1.5 mg/l nordiazepam and less than 0.1 mg/l oxazepam. The nordiazepam and oxazepam half-lifes were reduced to 42 h and 30 h respectively. The concomitant clinical improvement authorized the weaning from ventilation on day 12. CONCLUSION: This is the first report of the use of enterodialysis to treat severe benzodiazepine poisoning in a neonate. Depuration of the toxin was accelerated and the duration of intensive care was shortened thanks to this technique.

UNLABELLED: Disturbances in bone mineralization are frequent in cystic fibrosis but few studies have focused on the use of biphosphonates in this indication, and none on the use of oral etidronate. We report our experience using this latter treatment. METHODS: The study was retrospective and included five children and three adults with cystic fibrosis (six males and two females) aged seven to 30 years with Z-scores for lumbar bone density lower than -2 SD after one year of calcium (1 g/day) and vitamin D (900 UI/day and 300,000 UI/6 months) supplementation. All were treated during one year with etidronate: four courses of 15 days (one course per trimester) with doses ranging from 4 to 8 mg/kg per day. Calcium and vitamin D supplementation was continued between the etidronate treatment course. Total body and lumbar bone mineral density (BMD) were measured three times: at the beginning and the end of the year of calcium and vitamin D supplementation and at the end of the year of supplementation plus the four courses of etidronate treatment. RESULTS: The increase in BMD in absolute value (g/cm2) and in Z-score was significantly higher (P <0.05) after the year of combined supplementation and etidronate treatment (total body g/cm2: 3+/-1%, Z-score: 2+/-1% and lumbar spine g/cm2: 6+/-5%, Z-score: 3+/-4%) than after supplementation alone (total body g/cm2: -1+/-3%, Z-score: -4+/-3% and lumbar spine g/cm2: -1+/-3%, Z-score: -4+/-4%). Supplementation alone improved the total BMD in only one patient and the lumbar BMD in three, whereas after etidronate treatment the total and lumbar BMD were improved in the eight patients. None of the patients presented with side effects that could be attributed to the treatment. CONCLUSION: Oral etidronate treatment is well-tolerated and capable of improving bone mineralization in patients with cystic fibrosis. Further work will be necessary to determine the optimal dosage and the optimal frequency for the treatment series.

BACKGROUND: Pseudomembranous colitis is a rare and serious complication of treatment by antibiotics. The case of a patient with a protracted pseudomembranous colitis followed by two relapses is reported. CASE REPORT: A 4 year-old boy was admitted after 18 days of profuse and feverish diarrhea. He had been given amoxycillin for 10 days, one and a half months previously. His temperature was 40 degrees C; he had abdominal pain and leucocytosis was 30,000/mm3. The situation rapidly improved with digestive rest and i.v. antibiotic therapy. Relapse of diarrhea together with bilious vomiting and acute abdominal pains required readmission three days after his discharge. Search for Clostridium difficile in stools remained negative. The diagnosis of pseudomembranous colitis was confirmed by sigmoidoscopy and intestinal biopsy. The patient was given parenteral nutrition for 3 weeks and vancomycin. The disease was complicated by anasarca related to severe protein-loosing enteropathy but evolution was finally favourable after a two month period. CONCLUSION: Pseudomembranous colitis remains a serious affection in childhood; its prognosis largely depends on the precocity of diagnosis and treatment.

OBJECTIVE: The study was carried out by the GFHGNP to determine the annual incidence of symptomatic celiac disease in children. PATIENTS AND METHODS: The diagnostic criteria were: symptomatic patients diagnosed under 15 years of age during 1996, villous atrophy and positivity of antigliadin and/or other antibodies. Cases were collected from referral centers, general hospital pediatric departments and private pediatricians with endoscopic practice. RESULTS: The study involved roughly half of the French pediatric population in 41 out of the 95 French districts. In all, 124 patients were collected: 76 girls and 48 boys. By geographical areas, in 30 districts where collection of data was complete which counted 186,285 births, the yearly incidence varied from 1/1731 births to 1/3110. (0.57@1000 to 0.32@1000). On the whole there were 77 cases i.e. an annual incidence of 1/2419 or 0.41@1000 (confidence interval 95%: 0.32 to 0.50@1000). Lower incidences were observed in the district of Paris: 1/4865 (0.21@1000) and Lyon: 1/3310 (0.27@1000). Those lower incidences could be explained by the difficulties of collecting the data in the biggest urban areas. The first signs occurred before one year of age in 73% of the cases, during the second year of life in 20.5% and after 3 in only 6.5%. The diagnosis was made before 2 years of age in 77% of the cases and after 3 in only 13%. In order of frequency symptoms were: failure to thrive (80%), diarrhea (59%), anorexia (59%), abdominal distension (57%), weight under 2 standard deviations (43%), short stature (43%). CONCLUSION: Compared with previous studies in two French districts between 1975 and 1990, the annual incidence of symptomatic celiac disease in children appears to be on the rise. The usual clinical signs continue to be observed.

Lupus erythematosus profundus (panniculitis) is an unusual clinical variant of lupus erythematosus in which the lesions occur in deeper corium and panniculus. The diagnosis usually causes difficulty. Both reported cases are similar and concern young men with subcutaneous nodules appearing on the face and leaving depressed areas. Histological examination reveals a marked infiltrate in the dermis especially around the skin appendages, reaching the deep dermis and the fat tissue; this infiltarte is composed mainly of lymphocytes and histiocytes. Some moderate epidermal changes are present: liquefaction degeneration of the basal cell layer, epidermal atrophy, thickening of basement membrane (P. A. S.). Direct immunofluorescence of the lesions showed, in one case IgG deposits at the dermo-epidermal junction. Ultrastructural findingd are similar in both cases and may be an important point of diagnosis for isolated forms: -- tubular structures "paramyxo-virus-like-inclusions" are present in dermal infiltrate, endothelial cells and sometimes in keratinocytes of the basal layer; -- the basal lamina has many folds and villous projections;-- vacuoles and concentric lamellar formations are observed inside keratinocytes. No clinical or immunological signs of systemic lupus were found. Antimalaric drugs clear up the nodules.

BACKGROUND: Dorfman-Chanarin syndrome is an uncommon condition characterized by non-bullous congenital ichtyosiform erythrodermia and lipid vacuoles in circulating leukocytes. CASE REPORT: We report an unusual presentation in a child who had a dry congenital ichtyosiform erythroderma. Blood smears revealed lipid vacuoles in granulocyte cytoplasm, leading to the diagnosis of Dorfman-Chanarin syndrome. The child also had liver and ophthalmologic involvement. DISCUSSION: Dorfman-Chanarin syndrome is a rare autosomic recessive hereditary disease (27 cases reported in the literature) related to the accumulation of neutral lipids in organ tissues. Clinical manifestations are dry congenital ichtyosiform erythroderma and lipid vacuoles in circulating granulocytes. The syndrome may be expressed more or less severely in several organs. Diagnosis is confirmed on blood smears. The vacuoles can also be observed in smears of heterozygous subjects and can serve as a screening test. The pathogenesis of Dorfman-Chanarin syndrome is poorly understood but appears to be related to perturbed intracellular triglyceride catabolism. Treatment is symptomatic.

INTRODUCTION: Congenital portosystemic shunts (CPS) are rare vascular malformations that lead to liver metabolic modifications. The aim of this study was to describe the management and outcome of CPS in children who were followed in the western region of France and to compare our experience to a literature review. PATIENTS AND METHODS: This retrospective study reports nine children with CPS who were followed in the western region of France between 2008 and 2013. RESULTS: Among these nine children, six were detected by prenatal ultrasonography, one had cholestatic jaundice during the postoperative period, one had cholestatic jaundice during the first days of life, and one had dyspnea and fatigue. Two children had liver tumors. The CPS was intrahepatic for four children and extrahepatic for two children. Three others had a patent ductus venosus. Among the intrahepatic shunts that were discovered before the age of 2 years, three closed spontaneously. The five other shunts were closed surgically or by interventional radiology techniques, after angiography for four children. After closure of eight shunts, the outcome was favorable for six children. Two children presented complications after surgery: portal hypertension and portal thrombus. CONCLUSION: When CPS is suspected, the diagnosis should be confirmed and complications should be investigated. Shunt closure restores portal flow and prevents complications.

BACKGROUND: Antineutrophil cytoplasmic antibodies (ANCA) are usually considered as serological markers of vasculitis (microscopic polyangiitis, granulomatosis with polyangiitis, and Churg-Strauss syndrome), but they have also been described in other diseases. They are rarely observed in children. Therefore, this study aims to describe the clinical spectrum associated with positive ANCA in children. PATIENTS AND METHODS: All the children below 15 years of age, admitted to the Angers University Hospital between June 2004 and June 2010 presenting with an ANCA-positive test by indirect immunofluorescence were included in this study. The exhaustive list of ANCA-positive children was obtained from the immunology unit. Six antigenic targets were routinely tested by Elisa, i.e., proteinase 3, myeloperoxidase, bactericidal permeability increasing protein, cathepsin G, elastase, and lactoferrin. Clinical and biological data were retrospectively collected. RESULTS: Thirty-seven children were identified with positive ANCA in this 6-year period. None of the antigenic targets tested was found in 21 patients. The most frequent diseases associated were inflammatory bowel disease (n=10), infections (n=6), hematological disease (n=5), and juvenile idiopathic arthritis (JIA) (n=4). Patients with JIA presented with a predominance of antielastase antibodies. CONCLUSION: In contrast to the findings usually observed in adults, we obtained a wide spectrum of clinical entities associated with positive ANCA in this cohort. In children, the ANCA test has 2 advantages: to diagnose systemic vasculitis and to differentiate inflammatory bowel disease. Patients with JIA seemed to have more frequent antielastase antibodies: in the future, this finding should be further investigated in larger prospective studies.

INTRODUCTION: Aquagenic palmoplantar keratoderma (APK) is a cutaneous phenomenon marked by the formation of edematous, translucent papules and plaques on the palms after water immersion. It can be observed in healthy subjects, but while this dermatosis is little known by practitioners treating these patients, most cases of APK have been described in patients with cystic fibrosis (CF). The primary objective of this study was to evaluate the frequency of APK in a population of children with CF. In addition, the relationship between APK and sex, genotype, pancreatic and pulmonary function, body mass index, and sweat chloride levels was analyzed. METHODS: This study was conducted in 60 children, 27 girls and 33 boys, aged 4 months to 18 years, followed at the CF care center at Angers (France) University Hospital, in whom CF had been confirmed by a positive sweat chloride level greater than 60 mmol. APK was determined by questioning searching for modifications of the palms noticed by the patient or his/her family after immersion in water and a clinical examination searching for the same signs before and after immersion of the right hand in a bucket of lukewarm water for 3 minutes (bucket sign). RESULTS: Forty-seven out of 60 children (78%) had a positive bucket sign. Thirty-eight upon these 47 children had already noticed modifications of the skin on their palms, appearing quickly during the bath and 6 had an edema and an increase in skin folds on the palms of the hands even before immersion of their hand in water. No genotype-phenotype correlations were detected in patients with APK, nor were there associations of APK with other phenotypic features of CF. CONCLUSION: APK is very frequent in patients with CF. It is most probably a consequence of the dysfunction of the CFTR protein. It should be systematically sought in all patients with CF. Its discovery in another context should suggest the diagnosis of CF or a carriage to the heterozygous state of a mutation involved in the disease.
