Genotype-Specific Cortisol Reserve in a Cohort of Subjects With Nonclassic Congenital Adrenal Hyperplasia (NCCAH). J Clin Endocrinol Metab 2024; 109:852-857. [PMID: 37715965 DOI: 10.1210/clinem/dgad546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 08/22/2023] [Accepted: 09/15/2023] [Indexed: 09/18/2023]
Abstract
CONTEXT Recent guidelines suggest that patients with nonclassic congenital adrenal hyperplasia (NCCAH) stop glucocorticoid therapy after achieving adult height. However, these guidelines do not differentiate between NCCAH genotype groups. OBJECTIVE Compare ACTH-stimulated cortisol and 17-hydroxyprogesterone (17OHP) levels, and the rate of partial cortisol insufficiency in subjects with NCCAH carrying one mild and one severe (mild/severe) mutation vs subjects with biallelic mild (mild/mild) mutations. METHODS Retrospective evaluation of the medical records of 122 patients who presented with postnatal virilization and were diagnosed with NCCAH. Patients underwent standard intravenous 0.25 mg/m2 ACTH stimulation testing. Those with stimulated 17OHP level ≥40 nmol/L were screened for the 9 most frequent CYP21A2 gene mutations followed by multiplex ligation-dependent probe amplification. A stimulated cortisol level below 500 nmol/L was defined as partial cortisol deficiency. RESULTS Patients were subdivided into 3 genotype groups: 77 carried the mild/mild genotype, mainly homozygous for p.V281L mutation; 29 were compound heterozygous for mild/severe mutation, mainly p.V281L/p.I2Splice, and 16 were heterozygous for p.V281L, and were excluded from statistical evaluation. Stimulated cortisol levels were significantly lower in the mild/severe than in the mild/mild group (mean ± SD, 480 ± 90 vs 570 ± 125 nmol/L, P < .001). The mild/severe group exhibited a significantly higher rate of partial cortisol insufficiency (21/28, 75% vs 28/71, 39%, P = .004). Peak 17OHP was significantly higher in the mild/severe group (198 ± 92 vs 118 ± 50 nmol/L, P < .001). CONCLUSION The high rate of partial adrenal insufficiency in the mild/severe group underscores the need to carefully consider the value of glucocorticoid therapy cessation and the importance of stress coverage in this group.

Clinical and Molecular Characteristics and Long-term Follow-up of Children With Pseudohypoparathyroidism Type IA. J Clin Endocrinol Metab 2024; 109:424-438. [PMID: 37669316 DOI: 10.1210/clinem/dgad524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/07/2023]
Abstract
CONTEXT Pseudohypoparathyroidism type IA (PHPIA) is a rare genetic disorder characterized by hormone resistance and a typical phenotype named Albright hereditary osteodystrophy. Unawareness of this rare disease leads to delays in diagnosis. OBJECTIVE The aims of this study were to describe the clinical and molecular characteristics of patients with genetically confirmed GNAS mutations and to evaluate their long-term outcomes. METHODS A retrospective search for all patients diagnosed with PHPIA in 2 referral centers in Israel was conducted. RESULTS Nine children (8 females) belonging to 6 families were included in the study. Five patients had GNAS missense mutations, 2 had deletions, and 2 had frameshift mutations. Four mutations were novel. Patients were referred at a mean age of 2.4 years due to congenital hypothyroidism (5 patients), short stature (2 patients), or obesity (2 patients), with a follow-up duration of up to 20 years. Early obesity was observed in the majority of patients. Elevated parathyroid hormone was documented at a mean age of 3 years; however, hypocalcemia became evident at a mean age of 5.9 years, about 3 years later. All subjects were diagnosed with mild to moderate mental retardation. Female adult height was very short (mean -2.5 SD) and 5 females had primary or secondary amenorrhea. CONCLUSION Long-term follow-up of newborns with a combination of congenital hypothyroidism, early-onset obesity, and minor dysmorphic features associated with PHPIA is warranted and molecular analysis is recommended since the complete clinical phenotype may develop a long time after initial presentation.

Real life evaluation of the multi-organ effects of Lumacaftor/Ivacaftor on F508del homozygous cystic fibrosis patients. BMC Pharmacol Toxicol 2022; 23:80. [PMID: 36266606 PMCID: PMC9585743 DOI: 10.1186/s40360-022-00624-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 09/22/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Lumacaftor/Ivacaftor (LUM-IVA), a cystic fibrosis transmembrane conductance regulator (CFTR) protein corrector-potentiator combination, improves lung function and reduces pulmonary exacerbations (PEx) in F508del homozygous CF patients. However, the systemic effects of LUM-IVA outside the respiratory system have not yet been thoroughly investigated. METHODS A prospective, real-world, yearlong study was performed on F508del homozygous adult CF patients who commenced treatment with LUM-IVA. Pancreatic function, bone metabolism, fertility status, nutritional and pulmonary factors were evaluated. RESULTS Twelve patients, mean age 28.3 years (18.6-43.9) were recruited. Following 12 months of treatment, no changes were detected in glucose, insulin, c-peptide or BMI values. A significant relative decrease in mean alkaline-phosphatase levels (122.8 U/L vs 89.4, p = 0.002) and a trend toward an increase in calcium levels (9.5 vs 9.9 mg/dL, p = 0.074) were observed. A non-significant improvement in mean DEXA spine t-score after a year of treatment (-2.1 vs -1.6, n = 4, p = 0.11) was detected. Sweat chloride concentrations decreased significantly (-21.4 mEq/L; p = 0.003). Pulmonary outcome revealed improvement in spirometry values during the first three months (FEV1 by 5.7% p = 0.009, FEF25-75 by 4.3% p = 0.001) with no change in chest CT Bhalla score and CFQR after one year. There was also a significant decrease in parenteral antibiotic events (17 vs 8, p = 0.039) with shift from IV to oral antibiotics for PEx treatment. CONCLUSIONS After one year of treatment, stabilization was observed in the pancreatic indices, nutritional status, structure and function of the lungs, with a beneficial effect on bone mineral metabolism and CFTR function. Additional studies should investigate the effect of CFTR modulators on extra-pulmonary manifestations.

Abstract
BACKGROUND Prevalence of youth-onset type 2 diabetes (T2D) has increased worldwide, paralleling the rise in pediatric obesity. Occurrence and clinical manifestations vary regionally and demographically. OBJECTIVES We assessed the incidence, and clinical and demographic manifestations of youth-onset T2D in Israel. METHODS In a national observational study, demographic, clinical, and laboratory data were collected from the medical records of children and adolescents, aged 10-18 years, diagnosed with T2D between the years 2008 and 2019. RESULTS The incidence of youth-onset T2D in Israel increased significantly from 0.63/100,000 in 2008 to 3.41/100,000 in 2019. The study cohort comprised 379 individuals (228 girls [59.7%], 221 Jews [58.3%], mean age 14.7 ± 1.9 years); 73.1% had a positive family history of T2D. Mean body mass index (BMI) z-score was 1.96 ± 0.7, higher in Jews than Arabs. High systolic (≥ 130 mmHg) and diastolic blood pressure (≥ 85 mmHg) were observed in 33.7% and 7.8% of patients, respectively; mean glycosylated hemoglobin (A1c) level at diagnosis was 8.8 ± 2.5%. Dyslipidemia, with high triglyceride (>150 mg/dl) and low HDL-c (<40 mg/dl) levels, was found in 45.6% and 56.5%, respectively. Microalbuminuria and retinopathy were documented at diagnosis, 15.2% and 1.9%, respectively) and increased (36.7% and 4.6%, respectively) at follow-up of 2.9 ± 2.1 years. Criteria of metabolic syndrome were met by 224 (62.2%) patients, and fatty liver documented in 65%, mainly Jews. Psychosocial comorbidity was found in 31%. Treatment with metformin (45.6%), insulin (20.6%), and lifestyle modification (18%) improved glycemic control. CONCLUSION Youth-onset T2D in Israel has increased significantly and presents a unique profile.

Abstract
OBJECTIVE To evaluate the incidence and severity of ketoacidosis (DKA) at type 1 diabetes diagnosis during the first wave of the coronavirus disease 2019 (COVID-19) pandemic in Israel. RESEARCH DESIGN AND METHODS A population-based study the product of a national collaboration of Israeli pediatric diabetes centers investigated the presentation of childhood-onset type 1 diabetes. The frequencies of DKA and severe DKA observed during the COVID-19 period from March 15, 2020 (commencement of the first nationwide lockdown) until June 30, 2020 were compared with the same periods in 2019, 2018, and 2017 using multivariable logistic regression, adjusting for age, sex, and socioeconomic position. RESULTS During the COVID-19 period, DKA incidence was 58.2%, significantly higher than in 2019 (adjusted OR [aOR] 2.18 [95% CI, 1.31-3.60], P = 0.003); 2018 (aOR 2.05 [95% CI, 1.26-3.34], P = 0.004); and 2017 (aOR, 1.79 [95% CI, 1.09-2.93], P = 0.022). The incidence of severe DKA was 19.9%, significantly higher than in 2018 (aOR, 2.49 [95% CI, 1.20-5.19], P = 0.015) and 2017 (aOR, 2.73 [95% CI, 1.28-5.82], P = 0.009). In 2020, admissions and duration of stay in the intensive care unit were higher than in previous years (P = 0.001). During the COVID-19 pandemic, children aged 6-11 years had higher incidences of DKA (61.3% vs. 34.0%, 40.6%, and 45.1%, respectively, P = 0.012), and severe DKA (29.3% vs. 15.1%, 10.9%, and 5.9%, respectively, P = 0.002). CONCLUSIONS The dramatic increase in DKA at presentation of childhood-onset type 1 diabetes during the COVID-19 pandemic mandates targeted measures to raise public and physician awareness.

Abstract
CONTEXT Pregnancy achievement in an infertile patient with 17,20-lyase deficiency. OBJECTIVE To study and describe the achievement of successful pregnancy and delivery in a patient with 17,20-lyase deficiency. METHOD Controlled ovarian stimulation (COS) and in vitro fertilization (IVF), cryopreservation of embryos and frozen-thawed embryo transfer (ET). Controlled ovarian stimulation, follicular aspiration egg retrieval, IVF, embryo cryopreservation, thawed ET. A 24-year-old, infertile patient with 17,20-lase deficiency. RESULTS Isolated 17,20-lyase deficiency is caused by mutations in the CYP17A1 gene (coding for cytochrome P450c17), POR (coding for cytochrome P450 oxidoreductase), and CYB5A (coding for microsomal cytochrome b5) genes. A 24-year-old patient with 17,20-lyase deficiency had undergone IVF with gonadotropin releasing hormone agonist (GnRHa) protocol, prednisone, and gonadotropins. After the human chorionic gonadotropin (hCG) trigger, 37 oocytes were retrieved, 25 ova fertilized, and 17 embryos cryopreserved. After menstrual bleeding, the endometrium was stimulated with oral estradiol, under progesterone suppression with long acting GnRHa and prednisone. When endometrial width of 8.5 mm was reached, vaginal progesterone was added, while gradually decreasing prednisone. On the fourth day of progesterone supplement, 2 thawed embryos were transferred. After 11 days of human menopausal gonadotropin (hMG), estradiol concentration moderately increased, but progesterone levels remained high; therefore, no fresh ET was performed. Twelve days after thawed ET, hCG was positive, and 7 days later, an intrauterine gestational sac was detected, but the pregnancy ended in missed abortion. After 2 months, another frozen-thawed embryo transfer (FET) was performed, generating a normal gestation, which ended in successful delivery. CONCLUSION Pregnancy can be achieved in patients with 17,20-lyase deficiency, by IVF, freezing all embryos, and ET in a subsequent cycle, while suppressing endogenous ovarian progesterone with a GnRHa and adrenal suppression with high-dose glucocorticoids.

Abstract
CONTEXT Congenital adrenal hyperplasia (CAH) was among the first genetic disorders included in newborn screening (NBS) programs worldwide, based on 17α-hydroxyprogesterone (17-OHP) levels in dried blood spots. However, the success of NBS for CAH is hampered by high false positive (FP) rates, especially in preterm and low-birthweight infants. OBJECTIVE To establish a set of cutoff values adjusting for both gestational age (GA) and birthweight (BW), with the aim of reducing FP rates. DESIGN This cross-sectional, population-based study summarizes 10 years of experience of the Israeli NBS program for diagnosis of CAH. Multitiered 17-OHP cutoff values were stratified according to both BW and GA. PARTICIPANTS A total of 1,378,132 newborns born between 2008 and 2017 were included in the NBS program. RESULTS Eighty-eight newborns were ultimately diagnosed with CAH; in 84 of these, CAH was detected upon NBS. The combined parameters-adjusted approach significantly reduced the recall FP rate (0.03%) and increased the positive predictive value (PPV) (16.5%). Sensitivity among those referred for immediate attention increased significantly (94%). There were four false negative cases (sensitivity, 95.4%), all ultimately diagnosed as simple-virilizing. Sensitivity and specificity were 95.4% and 99.9%, respectively, and the percentage of true-positive cases from all newborns referred for evaluation following a positive NBS result was 96%. CONCLUSIONS The use of cutoff values adjusted for both GA and BW significantly reduced FP rates (0.03%) and increased overall PPV (16.5%). Based on our 10 years of experience, we recommend the implementation of this two parameter-adjusted approach for NBS of classic CAH in NBS programs worldwide.

Abstract
Williams-Beuren syndrome is a rare neurodevelopmental disorder caused by deletion of 1.5-1.8Mb genes on chromosome 7q11.23. The syndrome was first described as a triad of supra-valvular aortic stenosis, mental retardation, and distinctive facial features. Our patient was referred due to audible inspiratory stridor when he was seven days old. Following endoscopy he was diagnosed with bilateral vocal cord paralysis and was eventually intubated due to respiratory de-compensation followed by tracheotomy. On further workup he was diagnosed with hypothyroidism. Genetic workup supported the diagnosis of Williams-Beuren syndrome. We report here a case with an unusual clinical presentation.

Abstract
There are numerous surgical approaches for oro-antral-fistula (OAF) closure. Secondary sinus disease is still considered by many experts a relative contra indication for primary closure. To describe a single-stage combined endoscopic sinus surgery and per-oral buccal fat pad (BFP) flap approach for large OAF causing chronic maxillary sinusitis. The records of all the patients with OAF and chronic manifestations of secondary rhinosinusitis that were treated between 2010 and 2013 in our tertiary care medical center were reviewed. The exclusion criteria were: OAF 5 mm, resolved sino-nasal disease, OAF secondary to malignancy, recurrent fistula, medical history that included radiotherapy to the maxillary bone and age <18 years. Each procedure was performed by a team consisting of a rhinologist and a maxillofacial surgeon. The surgical approach included an endoscopic middle antrostomy with maxillary sinus drainage, and a per-oral BFP regional flap for OAF closure. Total OAF closure, complications and need for revision surgeries. Forty-five patients that underwent OAF closure together with sinus surgery using a combined endoscopic sinus surgery (ESS) and BFP flap approach met the inclusion criteria. There were 28 males and 17 females with a mean ± SD age of 53.5 ± 14.9 years (range 22-80 years). The presenting signs and symptoms included purulent rhinorrhea (n = 22, 48.9%), foreign body in sinus (n = 10, 22.2%) nasal congestion (n = 7, 15.5%), halitosis (n = 6, 13.3%) and pain (n = 5, 12.2%). Surgical complications included local pain (n = 2, 4.4%), persistent rhinitis (n = 2, 4.4%) and synechia (n = 1, 2.2%). One patient required revision surgery due, to an unresolved OAF. The OAF of all the other 44 patients (97.8%) was closed after the first procedure and the paranasal sinuses on the treated side were completely recovered. The mean follow-up time for the group was 7.6 ± 4.3 months (7-21 months), and no untoward sequelae or recurrence were reported. Combined, one step, endoscopic Maxillary sinus drainage together with per-oral BFP flap approach is an efficacious surgical approach for safe closure of OAFs that are complicated with secondary chronic maxillary sinusitis.

Abstract
Nonclassical 21-hydroxylase deficiency (NC21OHD) manifests with various degrees of post natal virilization. The length of CAG repeats of the androgen receptor gene (AR) is inversely correlated to activity of the human androgen receptor (AR) and affects phenotype of several androgen-dependent disorders. The aim of the study was to investigate the associations between CAG repeat length and the phenotype of females with NC21OHD. CAG repeat length and AR inactivation were assessed in females with NC21OHD, and related to their clinical presentation. CAG repeat length and AR inactivation were assessed in 119 females with NC21OHD. Biallelic mean (BAM) of the CAG repeat length and the weighted BAM (WBAM) were related to various clinical parameters. Age at diagnosis and age of menarche positively correlated with BAM (r=0.22, p=0.02, and r=0.23, p=0.01, respectively). A shorter (<25) BAM was associated with younger age at diagnosis (14.8 vs. 21.4 years, p<0.01), at adrenarche (8.1 vs. 10.2 years, p<0.01) and gonadarche (9.9 vs. 11.2 years, p<0.01), and higher corrected height standard deviation score at diagnosis (0.77 vs. 0.15, p=0.01). Precocious pubarche and precocious puberty were more frequent in these with the shorter BAM. Results of WBAM were similar. The CAG repeat length of the AR gene contributes to the clinical diversity of the phenotype in females with NC21OHD.

Abstract
INTRODUCTION Literature from the past two decades has presented an insufficient amount of research conducted on the nursing practice environments of registered practical nurses (RPNs). The objective of this article was to investigate the barriers and facilitators to sustaining the nursing workforce in north-eastern Ontario (NEO), Canada. In particular, retention factors for RPNs were examined. METHODS This cross-sectional research used a self-administered questionnaire. Home addresses of RPNs working in NEO were obtained from the College of Nurses of Ontario (CNO). Following a modified Dillman approach with two mail-outs, survey packages were sent to a random sample of RPNs (N=1337) within the NEO region. Logistic regression analyses were used to determine intent to stay (ITS) in relation to the following factor categories: demographic, and job and career satisfaction. RESULTS Completed questionnaires were received from 506 respondents (37.8% response rate). The likeliness of ITS in the RPNs' current position for the next 5 years among nurses aged 46-56 years were greater than RPNs in the other age groups. Furthermore, the lifestyle of NEO, internal staff development, working in nursing for 14-22.5 years, and working less than 1 hour of overtime per week were factors associated with the intention to stay. CONCLUSIONS Having an understanding of the work environment may contribute to recruitment and retention strategy development. The results of this study may assist with addressing the nursing shortage in rural and northern areas through improved retention strategies of RPNs.

Abstract
We present two cases of transient central diabetes insipidus in preterm neonates with post-hemorrhagic hydrocephalus. Although the association between intraventricular hemorrhage and diabetes insipidus has been described in preterm infants, the association between diabetes insipidus and hydrocephalus, and the fact that such central diabetes insipidus could be reversible with the reduction of ventricular size, either because of spontaneous resolution or the placement of ventriculo-peritoneal shunt is first described here in neonates.

Abstract
Congenital hyperinsulinism is characterized by hypoglycemia caused by several genetic disorders of inappropriate insulin secretion. Octreotide, an analogue of somatostatin, plays a major role in the pharmaceutical treatment of this condition. A 9-month-old infant treated with octreotide developed anicteric hepatitis with no other proven cause. After the discontinuation of this drug, the liver enzymes declined rapidly. Liver function tests should be followed in patients receiving octreotide.

BACKGROUND Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycemia in infants. Its management can be extremely complicated, and may involve medical therapy and surgery. The mainstay of the treatment is to maintain normoglycemia, since hypoglycemia during infancy can have severe neurological consequences. OBJECTIVE To assess the cognitive and developmental levels and the adaptive skills achieved by children with CHI who were treated medically over the past decade. SUBJECTS AND METHODS Fourteen children with CHI, under the age of 10 years, who received medical treatment only, underwent a physical and neurological examination and standardized assessments that included the Bayley Scale of Infant and Toddler Development, 3rd Edition, or Kaufman Assessment Battery for Children, the Vineland Adaptive Behavior Scales and the Achenbach Child Behavior Checklist (CBCL) parent questionnaire form. RESULTS Twelve children (86%) achieved normal range scores in the cognitive and development assessments (Bayley Scale of Infant and Toddler Development or Kaufman Assessment Battery for Children). Only two showed cognitive achievements below the normal range. The Vineland questionnaire, which was based on parental report, showed below normal adaptive skills in eight patients (57%). CONCLUSIONS In contrast to previous studies showing a high prevalence of neurodevelopmental difficulties in children with congenital hyperinsulinism, our study showed normal cognitive achievements in most children. This may be attributed to the earlier recognition and better management of the disease in the past decade.

Abstract
The tight junction proteins (TJPs) are major determinants of endothelial cells comprising physiological vascular barriers such as the blood-brain barrier, but little is known about their expression and role in immune cells. In this study we assessed TJP expression in human leukocyte subsets, their induction by immune activation and modulation associated with autoimmune disease states and therapies. A consistent expression of TJP complexes was detected in peripheral blood leukocytes (PBLs), predominantly in B and T lymphocytes and monocytes, whereas the in vitro application of various immune cell activators led to an increase of claudin 1 levels, yet not of claudin 5. Claudins 1 and 5 levels were elevated in PBLs of multiple sclerosis (MS) patients in relapse, relative to patients in remission, healthy controls and patients with other neurological disorders. Interestingly, claudin 1 protein levels were elevated also in PBLs of patients with type 1 diabetes (T1D). Following glucocorticoid treatment of MS patients in relapse, RNA levels of JAM3 and CLDN5 and claudin 5 protein levels in PBLs decreased. Furthermore, a correlation between CLDN5 pre-treatment levels and clinical response phenotype to interferon-β therapy was detected. Our findings indicate that higher levels of leukocyte claudins are associated with immune activation and specifically, increased levels of claudin 5 are associated with MS disease activity. This study highlights a potential role of leukocyte TJPs in physiological states, and autoimmunity and suggests they should be further evaluated as biomarkers for aberrant immune activity and response to therapy in immune-mediated diseases such as MS.

Abstract
CONTEXT Congenital hyperinsulinism (CH) may be treated conservatively in many children with octreotide given by multiple sc injections or via an insulin pump. OBJECTIVE We describe two children treated with a once-monthly injection of a long-acting somatostatin analog. PATIENTS AND METHODS Both patients presented with hypoglycemia 30 min after birth and were subsequently diagnosed with CH. Patients were initially treated with diazoxide, hydrochlorothiazide, frequent feedings, and octreotide via an insulin pump. With this therapy, they were normoglycemic with a good growth rate, normal weight gain, and excellent neurodevelopment. Treatment with the long-acting somatostatin analog lanreotide acetate (Somatuline Autogel), administered by deep sc injection of 30 mg once a month, was started at the ages of 4½ and 4 yr, respectively. Octreotide infusion was gradually weaned over 1 month. Continuous glucose monitoring after discontinuation of pump therapy showed normoglycemia. The first patient has now been treated with the lanreotide acetate for over 5 yr, and the second for 3 yr. Treatment is well-tolerated, and both the patients and their parents are satisfied with the transition from pump therapy to once-a-month injection and prefer it to pump therapy. CONCLUSION Lanreotide acetate may be a safe and effective alternative to octreotide pump therapy in patients with CH, offering an improved quality of life. Longer follow-up of a larger patient group is needed.

Abstract
Synthetic peptide monomers can self-assemble into PNM such as nanotubes, nanospheres, hydrogels, etc. which represent a novel class of nanomaterials. Molecular recognition processes lead to the formation of supramolecular PNM ensembles containing crystalline building blocks. Such low-dimensional highly ordered regions create a new physical situation and provide unique physical properties based on electron-hole QC phenomena. In the case of asymmetrical crystalline structure, basic physical phenomena such as linear electro-optic, piezoelectric, and nonlinear optical effects, described by tensors of the odd rank, should be explored. Some of the PNM crystalline structures permit the existence of spontaneous electrical polarization and observation of ferroelectricity. The PNM crystalline arrangement creates highly porous nanotubes when various residues are packed into structural network with specific wettability and electrochemical properties. We report in this review on a wide research of PNM intrinsic physical properties, their electronic and optical properties related to QC effect, unique SHG, piezoelectricity and ferroelectric spontaneous polarization observed in PNT due to their asymmetric structure. We also describe PNM wettability phenomenon based on their nanoporous structure and its influence on electrochemical properties in PNM. The new bottom-up large scale technology of PNT physical vapor deposition and patterning combined with found physical effects at nanoscale, developed by us, opens the avenue for emerging nanotechnology applications of PNM in novel fields of nanophotonics, nanopiezotronics and energy storage devices.

Abstract
OBJECTIVE To determine serum adiponectin concentrations in adolescent girls with and without polycystic ovary syndrome (PCOS) and to assess possible correlations of adiponectin levels with insulin and androgen levels. DESIGN Prospective case-control study. SETTING Endocrine clinics in the community. PATIENTS Forty-four adolescent girls were grouped as follows: 14 were overweight [body mass index (BMI) standard deviation score >1.645] with PCOS; 16 were lean (BMI SDS <1.036) with PCOS; and 14 were lean (BMI SDS <1.036) without PCOS. Intervention Blood samples were collected from all girls between 8 and 11 am, after an overnight fast. MAIN OUTCOME MEASURES Serum levels of adiponectin, leptin, insulin, Müllerian-inhibiting substance, luteinizing hormone, follicle-stimulating hormone, testosterone, 17-alpha-hydroxyprogesterone, androstendione, dehydroepiandrosterone sulphate (DHEAS) and 17beta-oestradiol. RESULTS Adiponectin concentrations were significantly decreased in obese adolescents with PCOS (10.5 +/- 5.5 mug/ml) compared with that in lean girls with or without PCOS (16.9 +/- 8.64 and 18.0 +/- 7.4 mug/ml respectively). Leptin levels were significantly elevated in obese adolescents with PCOS compared with the levels in normal weight adolescents with PCOS, and compared with that in normal weight controls. Insulin levels were markedly higher in obese adolescents with PCOS compared with that in normal weight adolescents (12.3 +/- 12.2 vs. 4.5 +/- 2.9, P < 0.05), and compared with that in normal weight PCOS adolescents (7.4 +/- 4.9); however, this difference was not statistically significant. Insulin levels did not differ between normal weight adolescents with PCOS and normal controls. Adiponectin concentrations correlated inversely with BMI, leptin and insulin. CONCLUSIONS Hypoadiponectinaemia is evident only in obese adolescents with PCOS and therefore does not seem to be involved in the pathogenesis of PCOS in this age group.

Abstract
Sick premature infants may display transient hypothyroxinemia secondary to immaturity of the hypothalamic-pituitary axis. Therefore, early screening programs of such infants may be misleading. We present such a case report, with review of the literature and the following suggested recommendations. (1) Screening programs should report thyroid-stimulating hormone (TSH) as well as thyroxine (T(4)) levels in premature infants, which will allow the treating physicians to be aware of possible abnormality that needs to be followed. (2) Sick premature infants and other populations at risk should undergo a full serum thyroid function evaluation including free T(4) and TSH beyond the screening program at discharge or at 30 days of age, whichever comes first. (3) Physicians should use their clinical judgment and experience even in the face of normal newborn thyroid screening test and reevaluate for hypothyroidism when there is a clinical suspicion. Our case report is a reminder of the American Academy of Pediatrics guidelines with practical suggestions for extra caution to avoid missing primary hypothyroidism in sick premature infants.

Abstract
CONTEXT Traditionally, hydrocortisone (HC) replacement therapy in congenital adrenal hyperplasia (CAH) is given by three daily doses, albeit not necessarily of equal quantity. Although a higher dose in the morning better imitates the physiological diurnal variation, a late-night higher dose was suggested to better suppress early morning hypothalamic-pituitary-adrenal axis peak activity. Yet, increased night cortisol has been claimed to be associated with sleep disturbances and insomnia. OBJECTIVE Our objective was to evaluate evening vs. morning high-HC dose with respect to disease control, sleep pattern, and daytime activity in children with CAH. DESIGN An open-label, cross-over, randomized trial of 15 children with classical CAH was performed. Patients were randomized to receive 50% of the daily HC in the morning or evening for 2 wk; the other two doses included 25% of the daily dose each. OUTCOME MEASURES Disease control was assessed by 0800-h 17-hydroxyprogesterone, testosterone, androstenedione, and dehydroepiandrosterone sulfate on the last day of each treatment schedule. Sleep and daytime activity were assessed by a 7-d actigraph. RESULTS Basal morning androstenedione, 17-hydroxyprogesterone, dehydroepiandrosterone sulfate, and testosterone levels during the high-morning and high-evening HC treatment schedules were comparable. There were no significant differences in sleep or daytime activity. CONCLUSIONS With respect to disease control, sleep quality and daytime activity were not affected by treatment schedules. We recommend the high-morning dose schedule in replacement therapy of children with CAH.

Abstract
CONTEXT The CYP17A1 gene encodes many enzymatic reactions including 17alpha-hydroxylase and 17,20-lyase activities. Mutations that selectively ablate the 17,20-lyase activity, causing isolated 17,20-lyase deficiency, are exceedingly rare and may belong to the rarest of all disorders of steroidogenesis. We have previously reported an E305G mutation in the active site of CYP17A1 that apparently causes isolated 17,20-lyase deficiency. Expression studies suggested intact 17alpha-hydroxylase activity which was at odds with subnormal tetracosactrin stimulated cortisol in the patients. OBJECTIVES To investigate the in vivo activity of the adrenal enzymes, we used the metabolomics approach with urinary steroid profiling by gas chromatography-mass spectrometry. PATIENTS Of the 11 subjects investigated, 6 patients in the kindred were found to be homozygous, 4 members were asymptomatic heterozygous, and 1 was homozygous for the wild-type allele. RESULTS In the homozygous patients for E305G, both serum and urinary steroids showed a severe lack of androgens (C(19)-steroids) pointing to the absence of 17,20-lyase activities. Furthermore, precursor/product ratios of urinary steroid metabolites characterizing 17alpha-hydroxylase activity showed variable decreases in 17alpha-hydroxylase activities. CONCLUSIONS The results confirm the complete absence of 17,20-lyase activity in vivo, as in the in vitro expression studies. On the other hand, in vivo 17alpha-hydroxylase activity was partially impaired. Thus, the in vivo metabolic data seem to be more sensitive than the expression study and suggests that this mutation also impairs 17alpha-hydroxylase activity.

The diagnosis of androgen insensitivity syndrome (AIS) can now be made prenatally. We present a patient for whom the diagnosis of AIS was highly suspected prenatally, but the parents preferred to deny it. The clinical findings and the diagnostic evaluation after delivery are presented. A brief discussion of the syndrome, as well as the implications of possible prenatal diagnosis and how to approach it, are provided. Full multidisciplinary diagnostic work-up immediately after delivery, as well as awareness of possible prenatal diagnosis, is the responsibility of the primary care provider for the newborn with suspected AIS.

Abstract
The interrelationship between human leukocyte antigen immunogenetics and environmental factors and their contribution to the emergence of type 1 diabetes (T1D) were studied in Jewish immigrants from Ethiopia in Israel. This community displays high incidence of T1D, and is unique both by its ethnic segregation and its rapid exposure to a new environment after the immigration. The study population consisted of 152 Ethiopian Jews living in Israel, 33 with T1D and 119 unrelated controls. Human leukocyte antigen class II susceptible and protective alleles in the Jewish Ethiopian patients were similar to those in patients of other ethnic groups in Israel and in non-Jewish Ethiopian patients, with a few exceptions. Three haplotypes were markedly associated with diabetes in Jewish Ethiopian patients: DRB1*0301 DQA1*05 DQB1*02 (OR 4.4, p < 0.001); DRB1*0404 DQA1 03 DQB1*0302 (OR 19.2, p = 0.006), and DRB1*0405 DQA1*03 DQB1*0302 (OR 87.8, p < 0.001). The highly susceptible allele DRB1*0301 was more common in the general Ethiopian population (25.2%) than in all other ethnic groups in Israel, which may render this community prone to the disease. The age at onset of disease in patients with two susceptible haplotypes was negatively correlated with the duration of living in Israel (r = -0.621, p = 0.04). We concluded that ongoing exposure of genetically predisposed immigrants from Ethiopia to diabetogenic environmental factors eventually leads to a high incidence of overt diabetes in this ethnic group.

Abstract
OBJECTIVE To assess whether overweight children and adolescents, who often have poor dietary habits, are at increased risk of iron deficiency (ID). METHODS The study sample included 321 children and adolescents followed in two endocrine centers in Israel between 1999 and 2001. The subjects were divided into three groups on the basis of body mass index (BMI) for age and gender as follows: group 1-BMI below 85th percentile (normal weight); group 2-BMI above 85th, but below 97th percentile (overweight); and group 3-BMI above 97th percentile (obese). ID was defined as iron levels <8 micromol/l (45 mcg/dl), and iron-deficiency anemia (IDA) was defined as ID and hemoglobin level below 2 standard deviation score (SDS) for the mean for age and gender. RESULTS Iron levels below 8 micromol/l (45 mcg/dl) were noted in 38.8% of the obese children and 12.1% of the overweight children, compared with 4.4% of the normal-weight group (P<0.001). There was a significant negative correlation of low iron levels with BMI SDS (r=-0.44, P<0.001), but not with age or gender. Among the children with ID, 26.6% also had IDA. Groups 1, 2, and 3 accounted for 6.7%, 35%, and 58.3% of the children with IDA, respectively. CONCLUSIONS ID is common in overweight and obese children. A significantly greater proportion of obese than normal-weight children have IDA. Insufficient dietary intake of iron, whether absolute or relative to body mass, and increased iron needs may be a result of unbalanced nutrition or repeated short-term restrictive diets. Because of potentially harmful effects of ID, obese children should be routinely screened and treated as necessary.

Abstract
Registered nurses and registered practical nurses working on pediatric units in 35 Ontario general hospitals participated in a study that examined their perceptions and practices of family-centered care (FCC). The Family-Centered Care Questionnaire-Revised (FCCQ-R) was used to collect the data. The participants were asked to rate their level of agreement regarding necessary elements (perceptions) of family-centered care and whether these elements are part of their current work (practice). The participants had a reasonable knowledge of the necessary elements of family-centered care, but were not consistently including these in their every day work. A number of barriers to the implementation of family-centered care were also identified. Perception and practice scores were higher among those who had participated in continuing education on family-centered care than those who had not. The findings suggest that some nurses may be having difficulties shifting from a medical helping model of care to an enabling helping model of care, which is considered the foundation of family-centered care. Difficulties in implementing family-centered care appear to be systemic, both at the unit and organizational level. Based on the findings, implications for practice, education and research are suggested.

Abstract
Type 2 diabetes has been considered rare in children and adolescents. Recently, increase in the incidence of type 2 diabetes has been reported among adolescents in various parts of the world. We report the occurrence of type 2 diabetes among adolescents in Israel. A boy of 14 and girls of 16.5 and 17 were pubertal and extremely obese, with a body mass index (BMI) between 39-47 kg/m2. Acanthosis nigricans, elevated diastolic blood pressure, and hirsutism with menstrual disorders, were associated with insulin resistance, and should raise suspicion of type 2 diabetes. Significant obesity and strong family histories of type 2 diabetes appeared to be important risk factors. Since type 2 leads to long-term morbidity and mortality, its early identification and appropriate treatment are crucial.

Abstract
OBJECTIVE To evaluate the nasal complications after transnasal transsphenoidal operations for pituitary tumors, comparing two surgical techniques: traditional sublabial transseptal and endoscopic transseptal techniques. STUDY DESIGN We retrospectively evaluated by self-reported questionnaire and endoscopic examination the nasal condition of 40 consecutive patients with pituitary tumors: 20 patients had endoscopic surgery and 20 had surgery with the traditional sublabial technique. RESULTS Compared with the traditional technique, the endoscopic approach was associated with a shorter operative time (about 40 min), shorter hospitalization time (about half), absence of recurrent epistaxis snoring and denture problems, and lower incidence of septal perforation, synechia, and crust formation. Furthermore, loss of nasal tip projection was found only in the group that had surgery with the sublabial technique. CONCLUSIONS Endoscopically guided transseptal transsphenoidal surgery is simple to perform and time-saving, and it results in fewer nasal and denture complications than the sublabial technique. At the same time, it allows the surgeon all the benefits of the binocular microscopic surgical field that are associated with the traditional approach.

Abstract
Sensory loss in the operative area after superficial parotidectomy is one of the complications which disturbs the patient. The greater auricular nerve, which stems from the cervical plexus, supplies sensation to the area. Sacrifice of the nerve during superficial parotidectomy causes sensory loss in the area. We investigated the degree of sensory loss in the operative area after superficial parotidectomy in 10 patients in whom the posterior branch of the greater auricular nerve was preserved and compared the results with those in whom it was not, a year after operation. There was more sensory loss when the greater auricular nerve was sacrificed. We therefore suggest preserving the posterior branch of the greater auricular nerve during superficial parotidectomy if at all possible.

Abstract
Registered nurses (n = 72) working in 10 paediatric units in community hospitals in north-eastern Ontario, Canada, participated in a descriptive study investigating how nurses assess and manage pain in children. A four-part questionnaire was used to collect the self-reported data. Twenty-five (36%) of the respondents defined pain as an individual and personal experience and another 25 (36%) respondents defined pain as a more or less localized sensation or discomfort resulting from the stimulation of specialized nerve endings. In response to three different clinical situations, the subjects' mean pain ratings were: 5.72 for an infant; 7.34 for a 3-year-old; and 7.29 for a 12-year-old child. The criterion 'nurses' judgment' was cited as being used frequently in both the assessment and decision making process; however, there was indication that some of the current knowledge in the assessment and management of pain in children was not known or being used.

Abstract
Routine ultrasound examination in a pregnant 20-year-old woman at 32 weeks demonstrated a cystic structure in the fetal abdomen. Follow-up till term showed no substantial change in size. After birth the cyst could easily be palpated as an epigastric mass. Ultrasonography followed by a barium meal suggested, among other things, the diagnosis of gastric duplication. At exploratory laparotomy the cyst proved to be of adrenal origin. The diagnosis and therapeutic options are discussed.
