Pulmonary hypertension without any cardiovascular malformation was diagnosed by heart catheterization in a 4 year old girl with trisomy 21. A suspected obstructive sleep apnea syndrome was confirmed by polysomnography which revealed numerous obstructive apneas and hypopneas (apnea-index 23/h) with marked oxygen desaturation and a disturbed sleep pattern. Three months after adenotonsillectomy the mother reported her daughter having a quiet sleep without snoring. Polysomnography did not show any apnea nor any oxygen desaturation below 90%. A decrease of the pulmonary artery pressure was documented. Facial dysmorphias and muscle hypotonia predispose patients with trisomy 21 to obstructive sleep apnea, especially if hypertrophy of tonsills and adenoids coexist. Frequent arousals and hypoxia during sleep can result in failure to thrive and pulmonary hypertension. These consequences can be prevented by early diagnosis and treatment.

Various types of system reactions of men's organism to industrial migrations (Tyumen--in latitude 57 degrees north and Kharasavey in latitude 71 degrees north) and the influence of climate stress are determined. Type I reaction is characterised by a moderate increase of the watch and its subsequent normalisation. Thus the tendency to hypocoagulaemia and POL processes increase, and AOD activation of thrombocyte membranes and total phospholipids content increase in the statistically significant lysolecitin increase (p<0.05). Type II reaction is characterised by the hypertensive state for the whole period of the watch. Simultaneously with it a tendency to hypercoagulaemia, an increase of POL processes and AOD decrease of thrombocyte membranes as well as significant changes in the phospholipids spectrum with a considerable increase of lysolecitin and cardiolipin fractions are observed. Type III reaction is characterised by the development of signs of the asthenic symptocomplex, hypotonia and sleep disturbances. Thus, the tendency to hypocoagulaemia, POL processes activation and AOD decrease as well as decrease of total phospholipid content is observed.

The chromosome 9q subtelomere deletion syndrome (9qSTDS) is among the first and most common clinically recognizable syndromes to arise from widespread testing by fluorescent in situ hybridization (FISH) of subtelomere deletions. There are about 50 reported cases worldwide. Affected individuals invariably have severe hypotonia with speech and gross motor delay. The facial gestalt is distinct and features absolute or relative micro- or brachycephaly, hypertelorism, synophrys, and/or arched eyebrows, mid-face hypoplasia, a short nose with upturned nares, a protruding tongue with everted lower lip and down-turned corners of the mouth. Approximately half of affected individuals have congenital heart defects (primarily ASD or VSD). A significant minority have epilepsy and/or behavioral and sleep disturbances. A variety of other major and minor eye, ear, genital, and limb anomalies have been reported. Most patients have sub-microscopic deletions of the subtelomere region of chromosome 9q34.3 that range from <400 kb to >3 Mb. The 9qSTDS is caused by haplo-insufficiency of EHMT1, a gene whose protein product (Eu-HMTase1) is a histone H3 Lys 9 (H3-K9) methyltransferase. This was established by identification of three patients with features of the syndrome and either mutations or a balanced translocation in EHMT1. H3-K9 histone methylation is restricted to the euchromatin of mammals and functions to silence individual genes. Deletion size does not correlate with the severity of the 9qSTDS since patients with mutations in EHMT1 are as severely affected as those with submicroscopic deletions. Patients clinically suspected of having the 9qSTDS but with normal subtelomere deletion testing by FISH or MLPA should be considered for detailed 9q MLPA analysis and/or sequencing of EHMT1. EHMT1 is another example in the growing list of genes responsible for brain development that appear to play a role in chromatin remodeling. Published 2007 Wiley-Liss, Inc.

Application of dopamine agonists in the therapy of Parkinson's disease constitutes significant progress. The adverse effects of dopamine agonists in the treatment of this disease are caused by various action mechanisms and depend upon the composition and pharmacological characteristics of the drug, its impact upon the dopaminergic and non-dopaminergic receptors, as well as dosage and duration of treatment. The most important ones include: nausea and vomiting, orthostatic hypotonia, psychiatric syndromes, sleep disturbances, pleuropulmonary and retroperitoneal fibrosis, vasoconstrictive properties, oedema, hormonal disturbances, as well as dyskinesias. Knowledge of such adverse effects is necessary for each physician, although in Poland dopamine agonists are used in a minority of patients due to the significant costs of the treatment.

Smith-Magenis syndrome (SMS), the result of an interstitial deletion within chromosome 17p11.2, is a disorder that may include minor dysmorphic features, brachydactyly, short stature, hypotonia, speech delays, cognitive deficits, signs of peripheral neuropathy, scoliosis, and neurobehavioral problems including sleep disturbances and maladaptive repetitive and self-injurious behaviors. Physical and occupational therapists provide services for children who have the syndrome, whose genetic disorder is frequently not identified or diagnosed before 1 year of age. A comprehensive physical and occupational therapy evaluation was completed in nonidentical twins with one having SMS, using the Sensory Profile; Brief Assessment of Motor Function (BAMF); Peabody Developmental Motor Scales, Second Edition (PDMS-2); and Pediatric Evaluation of Disability Inventory (PEDI). This provides a framework for conducting assessments to enhance early detection and interdisciplinary management with this specialized population.

Smith-Magenis syndrome (SMS), which occurs as a result of an interstitial deletion within chromosome 17p11.2-p12, is a disorder that presents itself with minor dysmorphic features, brachydactyly, short stature, hypotonia, delayed speech, cognitive deficits and neurobehavioral problems including sleep disturbances and maladaptive repetitive and self-injurious behavior. We present a girl with full SMS phenotype. G-banding cytogenetic analysis showed normal 46,XX karyotype. Whole-genome array comparative genomic hybridization (CGH) was performed due to the severity of the phenotype and the unusual features present in the patient. An interstitial deletion in 17p11.2-p12, approximately 4.73 Mb in size was determined. Characteristic physical and behavioral phenotype strongly suggested SMS. This, to the best of our knowledge is the first patient with SMS reported in Turkey. We emphasize the need for whole genome analysis in multiple congenital abnormalities/mental retardation disorders with unusual and severe phenotypes.

Kleefstra syndrome (KS), previously known as the 9q subtelomeric deletion syndrome (9qSTDS) is caused by haploinsufficiency of the EHMT1 gene. Both a single mutation and 9q34 microdeletions encompassing the entire gene can be responsible for this syndrome which is characterized by intellectual disability, hypotonia, and typical dysmorphisms, and may be associated with congenital heart and/or renal defects and epilepsy. Its behavioral phenotype has recently been described and comprises particular sleep disturbances and apathy. In this report, the evolution of the behavioral profile of KS is outlined by the description of three female patients aged 19, 33, and 43 years, respectively. In two patients, the syndrome was caused by an intragenic mutation and in the third by a 9q34 microdeletion encompassing the EHMT1 gene. MRI scanning of the brain in the two eldest patients demonstrated multifocal subcortical signal abnormalities. In general, the severity of the behavioral and motor deficiencies increased over time and became apparent after adolescence. It is concluded that the "regressive" phenotype of KS seems to be associated with the EHMT1 gene in particular. In addition, the utility of uncritical use of a classificatory diagnostic approach is discussed in the context of the motor and motivational disturbances that are prominent in this syndrome.

The 22q13.3 deletion, or Phelan-McDermid syndrome, is characterized by global intellectual disability, generalized hypotonia, severely delayed or absent speech associated with features of autism spectrum disorder, and minor dysmorphisms. Its behavioral phenotype comprises sleep disturbances, communication deficits, and motor perseverations. Data on psychological dysfunctions are so far not available. Previous studies have suggested that the loss of one copy of the gene SH3 and multiple ankyrin repeat domains 3 (SHANK3) is related to the neurobehavioral phenotype. Additional genes proximal to SHANK3 are also likely to play a role in the phenotype of patients with larger deletions. The present paper describes two adult brothers with an identical 2.15 Mb 22qter (22q13.32q13.33) deletion, of whom the youngest was referred for evaluation of recurrent mood changes. In both patients, magnetic resonance imaging of the brain showed hypoplasia of the vermis cerebelli. Extensive clinical examinations led to a final diagnosis of atypical bipolar disorder, of which symptoms fully remitted during treatment with a mood stabilizer. In the older brother, a similar psychopathological picture appeared to be present, although less severe and with a later onset. It is concluded that the behavioral phenotype of the 22q13.3 deletion syndrome comprises absent or delayed speech and perseverations with associated autistic-like features, whereas its psychopathological phenotype comprises an atypical bipolar disorder. The latter may have implications for the treatment regime of the syndrome-related behavioral disturbances.

The Smith-Magenis syndrome (SMS) is a rare microdeletion dysmorphic syndrome (interstitial microdeletion of chromosome 17p11.2), which occurs sporadically. Mutations in the RAI1 gene are found in part of the patients. SMS is characterized by intellectual disability and behavioural disturbances (sleep disturbances, hyperactivity, attention deficit, self-injury behaviour), craniofacial dysmorphism and defects of other organs and systems (teeth, eyes and upper respiratory and hearing disturbances, short stature, brachydactyly, scoliosis, cardiac and genitourinary defects). There are also neurological problems (muscular hypotonia, peripheral neuropathy, epilepsy and decreased sensitivity to pain). Many of the features that appear in the SMS may occur in other genetic syndromes, which may cause diagnostic difficulties. We report two cases of late diagnosed patients with the Smith-Magenis syndrome. Additionally, we present a review of literature and differential diagnosis. This may help in making the diagnosis and in giving optimal medical and psychological care to patients with SMS.

Patients with chronic widespread pain often present with musculo-skeletal pain and therefore often initially contact an orthopaedist. For these patients fibromyalgia syndrome is an important differential diagnosis. Recommendations for the diagnosis of and therapy for fibromyalgia syndrome based on the recent German S3 guidelines for fibromyalgia syndrome (AWMF registration number 041/004) are outlined in this paper. These guidelines were developed under the coordination of the German interdisciplinary association for pain management DIVS and two patient support groups. The history of a typical symptom complex and the exclusion of relevant somatic causes for the pain are epecially relevant for the diagnosis of fibromyalgia syndrome. Besides the exclusion of relevant orthopaedic causes for the pain, psycho-social aspects should always be evaluated. According to the modified ACR criteria 2010, chronic widespread pain and accompanying sleep disturbances and a physical as well as mental state of exhaustion lead to the diagnosis of fibromyalgia syndrome. It is not mandatory to check tender points (ACR 1990 criteria). A graduated treatment approach depending on the severity level of the fibromyalgia syndrome in the individual patient is recommended. Active treatment options (aerobic training, meditative movement therapies, strength training) should be preferred to any drug therapy in the long-term treatment of fibromyalgia. If indicated, amitryptiline or duloxetine may be used to treat accompanying depressive or generalised anxiety disorder. Muscle relaxant medication, non-steroidal anti-inflammatory drugs and strong opioids should be avoided. The multimodal pain therapy considering all psycho-social aspects is a promising treatment option for fibromyalgia syndrome of moderate to high severity.
