Intracranial germ cell tumours. A review with special reference to endocrine manifestations

EPIDEMIOLOGY

Intracranial germ cell tumours (icGCTs) represent 3-15% of primary paediatric intracranial neoplasms with a considerable geographical variation in incidence. Ninety percent of patients diagnosed with icGCTs are under 20 years of age.

PATHOLOGY

Histologic characteristics and investigation of the tumour markers β-human chorionic gonadotropin (β-hCG) and alpha-fetoprotein (AFP) help define the different categories of icGCTs. The tumours are divided into two major groups called germinomas and non-germinomatous GCTs (NGGCTs).

CLINICAL PRESENTATION

The clinical symptoms depend on the size and location of tumour in the brain, which is most commonly in the pineal or suprasellar region. Pineal GCTs often present with neurological symptoms because of their tendency to cause increased intracranial pressure. Suprasellar GCTs are often accompanied by endocrine abnormalities such as diabetes insipidus (DI), growth retardation and precocious or delayed puberty.

DIAGNOSIS

A combination of clinical findings, endocrine and tumour marker evaluation, spinal fluid cytology, magnetic resonance imaging (MRI) and biopsy helps verifying the diagnosis of an icGCT. A summary of published data (n = 97) revealed that >90% of patients at diagnosis had at least one endocrine abnormality, DI being the most common (>80%).

TREATMENT

Classification of tumour is important for choice of treatment and for prognosis. A combination of chemotherapy and radiotherapy is often used, since most icGCTs have a great sensitivity to these treatment modalities.

CONCLUSION

Endocrine symptoms are very frequently appearing in patients with icGCTs and they can present long before neuroimaging verification of tumour is possible. It is of the outmost importance to have the diagnosis of icGCTs in mind when children, adolescents and young adults are presenting with endocrine irregularities, because most icGCTs are very sensitive to radiotherapy and chemotherapy, and early onset of treatment is important in order to minimize morbidity and mortality.

Feeding problems in children with neurological disorders

INTRODUCTION

The aim of this study was to evaluate the prevalence of selected risk factors of weight deficiency in children with chronic metabolic diseases.

MATERIAL AND METHODS

The study group involved 160 children, from 2 months to 15 years (mean age 3.14 years), with diseases of the nervous system and body weight deficiency. According to the type of neurological disease the following groups of patients were separated: static encephalopathies, progressive encephalopathies, disorders of mental development of undetermined etiology, genetically determined diseases. As the exponent of malnutrition, z-score of weight-for-age standards was used. An inclusion criterion for the study group was z-score of weight-for-age < - 2SD. The analysed risk factors of body weight deficiency were: mode of feeding children, neurological disorders, oral motor dysfunction, diseases of other organs, gastrointestinal motility disorders (oral cavity, esophagus, intestines) and type of nutritional therapy.

RESULTS

The most advanced malnutrition was in children with progressive encephalopathies and genetically determined diseases. Seizures and muscular hypotonia were most common neurological disorders. Oral motor dysfunctions were observed in 40% of patients.

CONCLUSIONS

Malnutrition in children with neurological disorders is associated mainly with neurological deficits. In this group of children monitoring of somatic development and early nutritional intervention are necessary.

Association between clusters of diseases and polypharmacy in hospitalized elderly patients: results from the REPOSI study

BACKGROUND

Although the association between multimorbidity and polypharmacy has been clearly documented, no study has analyzed whether or not specific combinations of diseases influence the prescription of polypharmacy in older persons. We assessed which clusters of diseases are associated with polypharmacy in acute-care elderly in-patients.

METHODS

This cross-sectional study was held in 38 Italian internal medicine and geriatric wards participating in the Registro Politerapie SIMI (REPOSI) study during 2008. The study sample included 1155 in-patients aged 65 years or older. Clusters of diseases, defined as two or more co-occurring specific chronic diseases, were identified using the odds ratio (OR) for the associations between pairs of diseases followed by cluster analysis. Polypharmacy was defined as the prescription of five or more different medications at hospital discharge. Logistic regression models were run to analyze the association between clusters of diseases and polypharmacy.

RESULTS

Among clusters of diseases, the highest mean number of drugs (>8) was found in patients affected by heart failure (HF) plus chronic obstructive pulmonary disease (COPD), HF plus chronic renal failure (CRF), COPD plus coronary heart disease (CHD), diabetes mellitus plus CRF, and diabetes mellitus plus CHD plus cerebrovascular disease (CVD). The strongest association between clusters of diseases and polypharmacy was found for diabetes mellitus plus CHD plus CVD, diabetes plus CHD, and HF plus atrial fibrillation (AF).

CONCLUSIONS

The observed knowledge of the relationship among co-occurring diseases and polypharmacy should help to identify and monitor older in-patients at risk of polypharmacy.

Hypothesis-driven weight of evidence framework for evaluating data within the US EPA's Endocrine Disruptor Screening Program

"Weight of Evidence" (WoE) approaches are often used to critically examine, prioritize, and integrate results from different types of studies to reach general conclusions. For assessing hormonally active agents, WoE evaluations are necessary to assess screening assays that identify potential interactions with components of the endocrine system, long-term reproductive and developmental toxicity tests that define adverse effects, mode of action studies aimed at identifying toxicological pathways underlying adverse effects, and toxicity, exposure and pharmacokinetic data to characterize potential risks. We describe a hypothesis-driven WoE approach for hormonally active agents and illustrate the approach by constructing hypotheses for testing the premise that a substance interacts as an agonist or antagonist with components of estrogen, androgen, or thyroid pathways or with components of the aromatase or steroidogenic enzyme systems for evaluating data within the US EPA's Endocrine Disruptor Screening Program. Published recommendations are used to evaluate data validity for testing each hypothesis and quantitative weightings are proposed to reflect two data parameters. Relevance weightings should be derived for each endpoint to reflect the degree to which it probes each specific hypothesis. Response weightings should be derived based on assay results from the test substance compared to the range of responses produced in the assay by the appropriate prototype hormone and positive and negative controls. Overall WoE scores should be derived based on response and relevance weightings and a WoE narrative developed to clearly describe the final determinations.

Endocrine complications of human immunodeficiency virus infection: hypogonadism, bone disease and tenofovir-related toxicity

Treatment with highly active antiretroviral therapy (HAART) has revolutionized care of patients with HIV infection. The cost of increased survival has been antiretroviral toxicity and increasing age-related co-morbidities that include significant metabolic issues. Hypogonadism was first described in the setting of advanced AIDS and can be primary or secondary. Data regarding treatment largely concern patients with wasting. Varied syndromes involving bone have been described in patients with HIV including osteonecrosis, low bone mineral density (BMD) and osteoporosis, and rarely osteomalacia. Low BMD leading to osteoporosis is the most common bone pathology and may be as a result of HIV infection, drug toxicity or co-morbidities. However, increasingly fragility fractures are reported in HIV-infected patients, suggesting bone demineralization in this population is of clinical relevance. Further research is required to understand its pathogenesis and determine effective management; however, initiation of antiretroviral therapy seems to accelerate (in the short-term) bone demineralization. One particular antiretroviral agent, tenofovir is widely used and is potentially implicated as having a greater role in long-term bone and renal dysfunction. As this population ages, screening for low BMD will become increasingly more important.

Endocrine changes in male HIV patients

AIMS AND OBJECTIVES

To determine the frequency of adrenal, thyroid and gonadal dysfunction in HIV positive male patients and to evaluate the endocrine function at different level of CD4 cell counts.

MATERIAL AND METHODS

A total of 150 male HIV positive subjects were included in study. The patients were divided in three groups on the basis of CD4 cell counts. "Group A": HIV positive with CD4 count<200/mm "Group B": HIV positive with CD4 count 200-350/mm3 and "Group C": HIV positive with CD4 count>350/mm3.

RESULTS

In "group A" (n=50) 2 patients had basal cortisol<5 microg/dl while 23 patients had basal cortisol>25 microg/ dl. 15 patients had subclinical hypothyroidism while 11 patients had overt hypothyroidism. 25 patients in this group had gonadal dysfunction: majority of them (24) had primary gonadal dysfunction (elevated LH). None of the patients in "group B" (n=50) had hypocortisolism while 11 patients had elevated cortisol; 18 had subclinical hypothyroidism while 4 had overt hypothyroidism while 17 patients were hypogonad, all having elevated LH. In "group C" (n=50) 2 patients had hypocortisolism and 5 had elevated cortisol; 12 patients had subclinical and one had overt hypothyroidism; 7 patients had primary hypogonadism and one had secondary hypogonadism. Overall 4(2.66%) had hypocortisolism while 39 (26%) had elevated cortisol; 45 (30%) had subclinical hypothyroidism while 16(10.66%) had overt hypothyroidism. Gonadal dysfunction was observed in 50 patients (33%) majority of them (48) had primary hypogonadism. On analysis of Pearson's correlation coefficient CD4 count has strong inverse correlation with basal cortisol (r=-0.301, p<0.0001), TSH (r=-0.257, p=0.002) and LH (r=-0.228, p=0.006), while there was a direct correlation with serum testosterone (r=0.175, p=0.037).

CONCLUSION

This pilot study has demonstrated a high incidence of endocrine dysfunction in HIV infected patient in this part of country. High incidence of thyroid and gonadal dysfunction may contribute to morbidity of the patients and have a bearing on quality of life of the HIV infected patients. Hypocortisolism was not that common but high level of cortisol may be a marker of stress due to HIV per se or due to associated infection. Many of these dysfunctions might be transient and a large longitudinal study should be undertaken to substantiate the finding of the present study.

[Neurobiological consequences of child sexual abuse: a systematic review]

OBJECTIVE

The results of several studies suggest that there is a critical timeframe during development in which experiences of maltreatment and sexual abuse may lead to permanent or long-lasting neurobiological changes that particularly affect the hypothalamus-pituitary-adrenal axis response. The aim of the present study was to provide an updated review on the main neurobiological consequences of child sexual abuse.

METHODS

We selected articles published between January 1999 and January 2010 in English or Spanish that focused on the neurobiological consequences of child sexual abuse available through Medline, Scopus and Web of Science. We also examined the references in published articles on the consequences of sexual victimization in childhood.

RESULTS

In this review we included 34 studies on neurobiological consequences, indicating different kinds of effects, namely: neuroendocrine, structural, functional and neuropsychological consequences, which affect a large number of victims.

CONCLUSIONS

The existing body of work on the neurobiological consequences of maltreatment shows the need to consider maltreatment and child sexual abuse as health problems that affect different areas of victims' lives, which would in turn favor the development of intervention and treatment programs that take these multiple effects into account.

[The dynamics of oncological morbidity of population of industrial city of Western Siberia]

The results of study of general and oncological morbidity of population of industrial City of Seversk in 1970-2005. It is established that against a background of decreasing of cumulative indicator of primary morbidity an increase of this indicator was observed as related to diseases of blood circulation system, diseases of endocrinal system and malignant neoplasms. The propagation of chronic forms of the diseases mentioned above and the diseases of respiratory system added. The primary morbidity of malignant neoplasms increased during all the period of the study. The particular attention is attracted by the increase of oncological morbidity in patients of young and able-bodied population. In the structure of male morbidity prevailed the diseases of digestive system, diseases of respiratory system and skin diseases, melanoma included. In the structure of female morbidity prevailed malignant neoplasms located in digestive system, breasts and genitals.

[Serum hormonal levels in diamond-extracting industry workers of Yakutia, with surface and underground type of work]

The authors studied influence of work type (surface or underground) on serum hormonal levels in male workers of "International" mine within diamond-extracting complex of Yakutia-Sakha Republic. The results obtained show compensation and adaptation changes of endocrine system in males engaged into underground work vs. those of surface work.

Hormonal regulation of energy-protein homeostasis in hemodialysis patients: an anorexigenic profile that may predispose to adverse cardiovascular outcomes

To assess whether endocrine dysfunction may cause derangement in energy homeostasis in patients undergoing hemodialysis (HD), we profiled hormones, during a 3-day period, from the adipose tissue and the gut and the nervous system around the circadian clock in 10 otherwise healthy HD patients and 8 normal controls. The protocol included a 40-h fast. We also measured energy-protein intake and output and assessed appetite and body composition. We found many hormonal abnormalities in HD patients: 1) leptin levels were elevated, due, in part, to increased production, and nocturnal surge in response to daytime feeding, exaggerated. 2) Peptide YY (PYY), an anorexigenic gut hormone, was markedly elevated and displayed an augmented response to feeding. 3) Acylated ghrelin, an orexigenic gut hormone, was lower and did not exhibit the premeal spike as observed in the controls. 4) neuropeptide Y (NPY), a potent orexigenic peptide, was markedly elevated and did not display any circadian variation. 5) Norepinephrine, marginally elevated, did not exhibit the normal nocturnal dip. By contrast, α-melanocyte-stimulating hormone and glucagon-like peptide-1 were not different between the two groups. Despite these hormonal abnormalities, HD patients maintained a good appetite and had normal body lean and fat mass, and there was no evidence of increased energy expenditure or protein catabolism. We explain the hormonal abnormalities as well as the absence of anorexia on suppression of parasympathetic activity (vagus nerve dysfunction), a phenomenon well documented in dialysis patients. Unexpectedly, we noted that the combination of high leptin, PYY, and NPY with suppressed ghrelin may increase arterial blood pressure, impair vasodilatation, and induce cardiac hypertrophy, and thus could predispose to adverse cardiovascular events that are the major causes of morbidity and mortality in the HD population. This is the first report attempting to link hormonal abnormalities associated with energy homeostasis to adverse cardiovascular outcome in the HD patients.

Cancers, infections, and endocrine diseases in women with endometriosis

OBJECTIVE

To assess the prevalence of patient-reported, physician-diagnosed comorbid conditions in women with endometriosis.

DESIGN

Cross-sectional study of self-reported survey data.

SETTING

Academic research.

PATIENT(S)

Four thousand three hundred thirty-one Endometriosis Association (EA) members reporting surgically diagnosed endometriosis.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Self-reported, physician-diagnosed infectious diseases, cancers, and endocrine diseases.

RESULT(S)

Nearly two-thirds of women reported one or more of the assessed conditions. Recurrent upper respiratory infections and recurrent vaginal infections were common and more likely in women responding to the EA survey. Melanoma was reported by 0.7% (n=29), breast cancer by 0.4% (n=16), and ovarian cancer by 0.2% (n=10). While ovarian cancer and melanoma were significantly more common than in the general population, breast cancer was surprisingly less common. Addison's disease and Cushing's syndrome were rare (0.2% and 0.1%, respectively).

CONCLUSION(S)

Respondents reported a higher prevalence of recurrent upper respiratory or vaginal infections, melanoma, and ovarian cancer than the general population. These findings document other potential associations related to the immune system, which may help focus future research into this disease.

Endocrine outcomes in endoscopic pituitary surgery: a literature review

BACKGROUND

Since the introduction of fully endoscopic surgery this new technique has been adopted with enthusiasm by many but not all pituitary surgeons. Whilst some advantages of minimal access have been recognised, the information on endocrine outcomes has been slow to accumulate.

METHOD

This literature review examined all the endoscopic papers for endocrine results and complication rates. Where adequate detail was provided these results were broken down by subtype and the pooled cure rates calculated.

FINDINGS

The review revealed that the fully endoscopic method is the equal of the microscopic technique for endocrine remission in functioning pituitary tumours. Furthermore the endoscopic results in functioning macroadenomas are substantially better than the microscopic results with similar complication rates.

CONCLUSIONS

Endoscopic pituitary surgery offers significant advantages over the microscopic technique and should become the standard method of pituitary adenoma surgery.

Medical comorbidities in autism: challenges to diagnosis and treatment

Ever since its original description by Leo Kanner in l943, autism has been generally defined by its clinical characteristics and core symptoms that include impaired social skills, isolated areas of interest, and delayed and disordered language. Over time, it has become apparent that autism is a heterogeneous disorder with regard to its clinical presentation, etiology, underlying neurobiology, and degree of severity. As a result, the termed diagnosis of autism spectrum disorders (ASDs) has come into common usage. With advancements in clinical care, there has come the appreciation that many ASD children, adolescents, and adults may have medically relevant disorders that may negatively impact their developmental progress and behavior, but which frequently go undetected. Many of these medical conditions are treatable, often resulting in improved developmental gains and quality of life for the patient and family. In addition, the possibility exists that some of these medical conditions may suggest the presence of important genetic and/or biologic markers, which, if identified, can refine our ability to be more precise in categorizing clinical and genetic subtypes within the autism spectrum.

Expanding boundaries of endocrinology

There have been huge advances in endocrine care as a consequence of improved biochemistry and diagnostic techniques as well as improved imaging. Specialist transethmoidal endoscopic surgery has improved results in pituitary tumour patients and minimally invasive parathyroid surgery has had the same consequence in patients with parathyroid disease. Multidisciplinary teams have improved outcomes in a number of areas and, as described above, endocrinologists are dealing with more in the way of endocrine disease to expand boundaries. Much work remains to be done particularly concerning the care of children and adults with late endocrine effects of cancer treatment and obesity.

[Frequency and prophylaxis of the most generalized diseases among young men of preinduction age]

Were shown causes of deficit of weight, growth of pathology of locomotor apparatus and psychic diseases among young men of preinduction age. The young men before the call-up need well-timed prophylactic observes, dispensary observe and health measures, aimed to improve the health.

Risk factors for idiopathic intracranial hypertension in men: a case-control study

OBJECTIVE

To identify risk factors for idiopathic intracranial hypertension (IIH) in men.

DESIGN

Case-control study. A 96-item telephone questionnaire, answered retrospectively, with cases recalling at the age of their diagnosis and controls recalling at the age of their corresponding case's diagnosis.

SETTING

Outpatient clinics in two US tertiary care centers.

PARTICIPANTS

The characteristics of 24 men with IIH were compared to those of 48 controls matched for sex, age, race, and World Health Organization body mass index (BMI) category.

MAIN OUTCOME MEASURES

Two previously validated questionnaires: the ADAM (Androgen Deficiency in Aging Males) questionnaire for testosterone deficiency and the Berlin questionnaire for obstructive sleep apnea (OSA), embedded within the telephone questionnaire. Analysis with Mantel-Haenszel odds ratios and mixed-effects logistic regression models accounted for matching.

RESULTS

Cases and controls had similar enrollment matching characteristics. Although matching was successful by BMI category, there was a small difference between BMI values of cases and controls (cases: median 31.7, controls: median 29.9; p=0.03). After adjustment by BMI value, men with IIH were significantly more likely than controls to have a positive ADAM questionnaire for testosterone deficiency (OR: 17.4, 95% CI: 5.6-54.5; p<0.001) and significantly more likely to have either a positive Berlin questionnaire for OSA or history of diagnosed OSA (OR: 4.4, 95% CI: 1.5-12.9; p=0.03).

CONCLUSIONS

Men with IIH are more likely than controls to have symptoms associated with testosterone deficiency and OSA. These associations suggest a possible role for sex hormones and OSA in the pathogenesis of IIH in men.

[Comprehensive examination of able-bodied populations from different Moscow districts to maintain and correct the health of healthy individuals]

A total of 1038 Muscovites (740 males and 298 females) aged 20 to 60 years were examined using a broad range of clinical and diagnostic methods. In the study cohort, the prevalence of all diseases taken together was 1533 cases per 1000 examinees, the number of cases being 1108.1 and 2590.6% per hundred among men and women, respectively. In males, endocrine diseases (27.3%) rated first, next were cardiovascular (23.5%) and digestive (18.8%) diseases that occupied the second and third places, respectively. In females, diseases of genital organs (breast, ovaries, corpus and cervix uteri) were the most common pathology (about 50%), cardiovascular (15.8%) and digestive (10.6%) diseases ranked second and third, respectively. Metabolic syndrome was virtually equally present in both sexes: 22.7% in males and 26.5% in females. The application of this approach can reveal abnormalities in their early stage, follow their course, and develop packages of adequate preventive measures.

[Neurofibromatosis type I--the pediatric endocrinologist's point of view]

AIM OF THE STUDY

A retrospective analysis of endocrine disorders in patients with neurofibromatosis type I consulted in the Children's University Hospital of Krakow in the period 2007-2010.

MATERIAL AND METHODS

The analysis included 60 patients (33 girls, and 27 boys) aged 1.2-32 years, mean 11.6 years. The patients were followed up by many health care professionals: neurologists (EEG), neurosurgeons (CT, MRI), ophthalmologists, psychologists, ENT specialists, anthropologists (the assessment of body height and weight), geneticists, endocrinologists and gynecologists (the assessment of puberty according to Tanner scale, diagnostics of short stature, precocious puberty), and cardiologists (echo-cardiography).

RESULTS

In the analyzed group of 60 patients, 46 were consulted by geneticists, 20 by endocrinologists, 19 by neurologists and cardiologists. The imaging of the central nervous system (CNS) was performed in 37 patients. Twenty-two patients presented with familial NF-I, 13 with sporadic NF-I, and in 25 patients, the family history was unavailable. Growth disorders were present in 27.7% of patients (13/47) that were referred to the anthropometric assessment. Short stature (height < or = (-) 2 SD) was recognized in 9/47 of children (19.1%). Tall stature (> (+) 2 SD) was recognized in 4/47 of patients (8.5%). All of the patients with tall stature presented with central precocious puberty (PD). Precocious puberty was also recognized in two children with normal stature. In all cases of PD, optic chiasm gliomas were recognized. Generally, organic CSN disorders were detected in 24 patients (63.2%). MRI revealed optic chiasm gliomas in 8 patients, 4 presented with gliomas of one or two optic nerves, 10 presented with hyperintensive areas on T2-weighted images, without enhancement after contrast injection, that may suggest the diagnosis of hamartoma of the CNS, and 2 with hydrocephaly.

CONCLUSIONS

1. The most common disorders of the somatic development revealed in NF-I patients are growth disorders: short stature and tall stature caused by central precocious puberty. 2. In view of the incidence of endocrine disorders in patients with NF-I, the authors suggest an endocrine consultation in each case of NF-I.

[Structural CNS abnormalities responsible for coincidental occurrence of endocrine disorders, epilepsy and psychoneurologic disorders in children and adolescents]

BACKGROUND

In the population of children and adolescents, epilepsy affects 0.5-1% of individuals; approximately 3% of general population suffer from non-epileptic seizures, while endocrine disorders are several times more frequent. All of the above factors result in a relatively common non-accidental occurrence of endocrine disorders, epilepsy and neuropsychiatric disorders. However, structural central nervous system (CNS) abnormalities that cause both endocrine and neurologic disorders seem to be markedly less common. No reports addressing this problem are available in the literature.

AIM OF THE STUDY

1) Assessment of the frequency of non-coincidental occurrence of epilepsy and endocrine disorders in inpatients and outpatients with structural CSN abnormalities managed in Department Endocrinology. 2) Presentation of diagnostic and therapeutic difficulties in these patients, and 3) An attempt at defining a common etiology of both disorders.

MATERIAL AND METHODS

A retrospective analysis of the medical records of the patients with coincidence of endocrine disorders and epilepsy and psycho-neurologic disorders (treated in Chair and Department of Children's and Adolescents Neurology, University Children's Hospital of Krakow or in another pediatric neurology center) and with organic CNS abnormalities (treated or followed up as inpatients and outpatient of Department of Pediatric Surgery, Children's University Hospital of Krakow, was performed. The patients were selected from among several thousands of children treated as inpatients and outpatients of the Department.

RESULTS

Various forms of symptomatic and idiopathic epilepsy and other psychoneurological disorders (disorders of behavior and emotions, obsession-compulsion syndromes, stereotypias, aggression, compulsive ideas and movements, anorexia or hypothalamic obesity) coincident with one or more endocrine disorders such as precocious or delayed puberty, multihormonal pituitary deficiency, panhypopituitarism and secondary hypothyroidism were detected in 42 patients with suprasellar arachnoid cyst (7 patients), septo-optic dysplasia (8 patients), craniopharyngioma (15 patients), glioma of the optic chiasm in neurofibromatosis type 1 (NF-1) (12 patients). There were no endocrine disorders in any of the ten patients with hamartoma of the hypothalamus and CPP. Endocrine and/ or neurological disorders did not resolve or were progressive after neurosurgery. Of 42 patients, a group of seven children representative for individual disorders was selected. In those patients, the etiology of both endocrine disorders, epilepsy and neuropsychiatric disorders was suspected to be common.

CONCLUSION

1. Various structural CNS abnormalities are the cause of concomitant epilepsy and endocrinopathy, although in some cases a direct impact of a genetic factor on the occurrence of both disorders or a mere coincidence cannot be ruled out. 2. Psychoneurological disorders usually precede the onset of endocrinopathy. 3. For this reason, MR or CT CNS imaging should be performed in any case of central neurological disorders, disorders of behavior, epilepsy, obsessive-compulsive syndrome, but also in patients with delayed psycho-motor development, delayed or accelerated growth and pubertal development. All of the above-mentioned manifestations may be symptoms of structural CNS abnormalities and their early treatment determines the child's future.

Epidemiologic factors causing cleft lip and palate and their regularities of occurrence in Estonia

OBJECTIVES

To study epidemiological factors causing development of cleft lip and palate and their occurrence regularities.

MATERIALS AND METHODS

This study included 583 cleft lip and palate patients and the information for statistical analyses was gathered from Tartu University Hospital.

RESULTS

19% of the patients had a cleft lip (CL), 39% of the patients had a cleft palate (CP), and 42 % of the patients had a cleft lip and palate (CLP). The ratio for different cleft types CL: CLP: CP was 1:2:2. In unilateral CLP and CL cases, the left side was affected 2.2 times more frequently than the right side. Boys had a CLP nearly 2.1 times more often than girls. CP was more common for girls (60%) than for boys (40%). 30% of children had multiple malformations. 2.6% of children with clefts were born premature, half of which had accompanying developmental anomalies. The average birth weight for cleft child was ~3400 grams. 6.8% of children with clefts had a birth weight below 2.5 kg. In case of children with clefts, the mother's age exceeded 30 years in 1/4 of cases and father's age in 1/3 of cases. Both parents were older than 30 years in 66% of the cases. 1/5 of both parents were older than 30 years. 1/3 of mothers of children with clefts had suffered psychological stress, 1/5 of mothers had done hard physical work. 1/5 of mothers had an exposure to teratogenic toxic substances. 15% of them received medications during the first trimester of pregnancy. 15% of mothers had experienced hormonal disorders.

CONCLUSIONS

As a result of the study we found a high occurrence rate of CP (CL: CLP: CP--1:2:2), which is similar to the studies conducted in Finland and Sweden. The reasons for this ratio need further research.

[Non-structural abnormalities of CNS function resulting in coincidence of endocrinopathies, epilepsy and psychoneurologic disorders in children and adolescents]

BACKGROUND

In the population of children and adolescents, epilepsy affects approximately 1% of cases, nonepileptic seizures are seen in approximately 3%, and endocrine disorders are several times more common. For this reason, coincidence of endocrine disorders and epilepsy and psychoneurologic disorders is frequent. Much less common are structural abnormalities (tumors, developmental abnormalities), and especially non-structural CNS abnormalities, resulting in coincidence of both disorders. There are no reports available in the literature that would address the problem.

AIM OF THE STUDY

1) Assessment of the frequency of coincidental epilepsy and endocrine disorders in patients without structural CSN abnormalities treated as outpatients and inpatients of Department of Endocrinology University Children's Hospital of Krakow. 2) Presentation of diagnostic and therapeutic difficulties in these patients, and 3) An attempt at defining the common etiology of both disorders.

MATERIAL AND METHODS

On the basis of ICD code patients with coincidance of endocrine disorders, epilepsy and psychoneurologic disorders were selected from several thousands of children treated between 2000 and 2009 in Pediatric Endocrinology Department. The neurologic disorders were diagnosed and treated in Chair and Department of Children's and Adolescents Neurology or in another pediatric neurology center.

RESULTS

Various forms of epilepsy (symptomatic or idiopathic) and other psychoneurological disorders (disorders of behavior and emotions, obsession-compulsion syndromes, stereotypias, aggression, autoaggression, or hypothalamic obesity) coincident with one or more endocrine disorders, such as growth disorders, disorders of pubertal development, obesity, thyroid diseases, adrenal diseases, hyperprolactinemia, hypoparathyroidism and ion metabolism disorders were diagnosed in 49 patients. The group included: i) children after cranial irradiation and chemotherapy due to medulloblastoma (3 patients), oligodenroglioma (1 patient), ependymoma (1 patient), optic chiasm glioma (2 patients), suprasellar germinal tumor (1 patient), ii) children with Hashimoto encephalopathy (2 patients), iii) children with Prader-Willi syndrome (20 patients), with Klinefelter syndrome (10 patients), with Albright syndrome (9 patients). Of the 49 patients, a group of 6 children representative for individual disorders was selected. In those patients, the etiology of both endocrine disorders, epilepsy and neuropsychiatric disorders was suspected to be common, and the diagnosis was usually delayed.

CONCLUSIONS

1. Cranial irradiation and chemotherapy, encephalopathy associated with Hashimoto disease and some of the syndromes with the chromosomal and genetic background are the causes of non-structural CNS abnormalities and coincidence of endocrinopathies, epilepsy and psychoneurologic disorders. 2. MR/CT CNS imaging should be performed in any case of central neurological disorders, disorders of behavior, epilepsy or seizures, but also in patients with delayed psycho-motor development, delayed or accelerated growth and pubertal development. All of the above-mentioned manifestations may be symptoms of structural CNS abnormalities and their early treatment determines the child's future. 3. Excluding structural CNS abnormalities allows for forming suspicions associated with diseases resulting in non-structural disorders of the CNS function, predisposing to coincidence of endocrine and neurological disorders. 4. In the diagnosis of Hashimoto's encephalopathy, a decisive factor is exclusion of structural, infectious, traumatic and metabolic causes, intoxications, epilepsy and presence of neuropsychiatric symptoms in patients with high level of against TPO antibodies. In cases of steroids resistance, a good therapeutic effect may be achieved by plasmapheresis, Rituximab therapy and progestagene inhibition of the menstrual cycle.

Pediatric otorhinolaryngologic manifestations of endocrinological pathologies

OBJECTIVE

Aim of the present review is to offer a concise but complete discussion about pathologies with pediatric otorhinolaryngological interest recognizing: (i) growth disorders, (ii) chromosomal disorders, and (iii) tumors.

METHODS

Pathologies characterized by a growth anomaly have been grouped, underlining the characteristics of otorhinolaryngological interest. Numerous syndromes typical of the pediatric age have been reported and classified according to the ailments of the orofacial district. Tumoral pathologies, for which the otorhinolaryngological operation is fundamental, have been descripted. We reviewed recent literature and older papers. We did not find recent literature regarding otorhinolaryngological features related to some of the pathologies described.

RESULTS/CONCLUSIONS

Otorhinolaryngologists should be familiar with pediatric disorders, since many of them have head and neck manifestations. This knowledge allows to treat them with a correct surgical approach, in order to implore children's quality of life.
