    The main criteria for diagnosis of the Currarino syndrome have been defined. Roentgenologic investigation of the lumbar-sacral spine in direct projection is indicated to all the patients with anorectal developmental defects, in particular with congenital anorectal stenosis. In detection of a specific defect of the terminal vertebrae, the performance of computed tomography of the pelvic bottom and nuclear magnetic resonance tomography of the lumbar-sacral spine is necessary. This permits to assess the nature of a presacral tumour and degree of dysplasia of the external and sphincter. Timely diagnosis of the Currarino syndrome in children with the anorectal developmental defects permits to avoid severe septic and functional complications in surgical intervention.

    Full Text Available Abstract Background Leiomyomatosis peritonealis disseminata (LPD is a rare disease in which multiple smooth muscle or smooth muscle-like nodules develop subperitoneally in any part of the abdominal cavity. No reports of multiple congenital malformations associated with LPD have been found in the English literature. Case presentation A 27 year-old patient referred to our gynaecology unit for pelvic pain, amenorrhoea, stress incontinence, chronic constipation and recurrent intestinal and urinary infections. Multiple congenital malformations had previously been diagnosed. Most of these had required surgical treatment in her early life: anorectal malformation with rectovestibular fistula, ectopic right ureteral orifice, megadolichoureter and hemisacrum. An ultrasound scan and computed tomography performed in our department showed an irregular, polylobate, complex 20 cm mass originating from the right pelvis that reached the right hypochondrium and the epigastrium. The patient underwent laparotomy. The three largest abdominal-pelvic masses and multiple independent nodules within the peritoneum were progressively removed. The histological diagnosis was of LPD. Conclusion The case we report is distinctive in that a rare acquired disease, LPD, coexists with multiple congenital malformations recalling a particular subgroup of caudal regression syndrome: the Currarino syndrome.

Nous rapportons le cas d�une fille de 4 ans et demi ayant ete admise en consultation de gastro-enterologie pediatrique pour constipation avec issue de selle a travers un orifice vulvaire. La radiographie du rachis avait montre une agenesie sacree. Le fistulo-scanner a mis en evidence une fistule recto-vaginale et l�IRM pelvienne a confirme l�agenesie sacree et a retrouve une meningocele anterieure. La decouverte d�une malformation ano-rectale doit faire chercher une autre anomalie de la triade de Currarino. Cette affection, rare, necessite une prise en charge medico-chirurgicale assez complexe.

  4. Currarino triad

    Nine cases of a syndrome are described, which is known as the ''Currarino triad'' and which belongs to the group of malformations in which there is a persistent neurenteric communication. The features of the triad consists of ano-rectal anomalies (particularly ano-rectal stenoses), a curved, but limited, sacro-coccygeal defect (''scimitar sacrum'') and a presacral tumour, which may be an anterior sacral meningocoele, a teratoma, a cyst (dermoid or neurenteric cyst) or a mixture of these. In at least 50% of cases, the triad is familial and autosomal dominant. Of our nine cases, seven were familial. A dangerous complication is meningitis due to infection of the cystic component, or fistula formation between the colon and spinal canal (one of our cases). Other complications are a fixed filum terminale (''tethered cord'') and malformations of the urogenital tract. The risk of malignancy in a teratoma is low, but exists. When considering the indications for surgery, this must be kept in mind, as must the risk of infection, and damage to neural structures during operation. In all cases of early obstipation the sacrum should be X-rayed in order to exclude a Currarino triad. The finding of a sacral defect and a presacral mass makes it essential to obtain CT of the pelvis with contrast in the distal gut and in the meningeal sac. The same is true for screening of the family (including views of the sacrum).

    Full Text Available OBJETIVO: Relatar o caso de uma criança com síndrome de Currarino diagnosticada após avaliação por episódios recorrentes de infecção urinária. DESCRIÇÃO DE CASO: Menina branca de dois anos, única filha de pais hígidos e sem história familiar de defeitos congênitos. A criança nasceu com imperfuração anal e com fístula retovestibular diagnosticadas no primeiro dia de vida. Por volta dos sete meses, começou a apresentar episódios recorrentes de infecção urinária, estabelecendo-se o diagnóstico de bexiga neurogênica. Na mesma ocasião, foi constatada a presença de agenesia parcial do sacro. A avaliação pela tomografia computadorizada e ressonância nuclear magnética de coluna identificou presença de fístula coincidente com a fosseta da transição lombo-sacral, observada ao exame físico; amputação da porção inferior da medula, com diminuição do número de raízes nervosas da cauda equina e massa pré-sacral de aspecto lipomatoso. Esta foi confirmada durante a cirurgia de correção do ânus imperfurado. A criança não apresentava outras dismorfias e a avaliação radiológica dos pais não identificou anormalidades sacrais. COMENTÁRIOS: A síndrome de Currarino é uma doença genética autossômica, dominante e rara caracterizada pela tríade formada por atresia anal, agenesia parcial do sacro e tumoração pré-sacral. Inclui teratomas, meningoceles, cistos entéricos e lipomas, como observado em nossa paciente. Crianças apresentando anormalidades anorretais deveriam ser sempre cuidadosamente avaliadas quanto à presença da síndrome de Currarino. A agenesia parcial do sacro é um forte indicativo da doença.OBJECTIVE: To report a patient with Currarino syndrome diagnosed after evaluation for recurrent urinary infections.

    Full Text Available Currarino syndrome (CS is a rare symptom complex comprising an anorectal malformation, a sacral bone abnormality and a presacral mass. Recurrent sepsis of the perianal area is a well-described post-operative morbidity. We report the case of a 4-year-old boy with CS and chronic perianal sepsis in the form of a draining sinus at the level of S5, which had plagued him since removal of a benign sacrococcygeal teratoma at the age of 1 year. Normal alfa feto protein and beta-human chorionic gonadotropin levels ruled out malignant recurrence of a sacrococcygeal teratoma, whilst an MRI showed a large presacral abscess with no fistulous connection to the rectum. Biopsy and drainage of the abscess was performed through a posterior sagittal approach and pus was sent for microscopy, culture and sensitivity. Microscopy demonstrated the presence of acid-fast bacilli, confirming infection with Mycobacterium tuberculosis (TB. A review of the literature revealed paucity in the documentation of microbes related to this common complication with no previous reports of TB as the aetiological pathogen. This case is of particular interest as the patient was not immunocompromised, had no TB contacts or history of previous TB infection, and highlights the importance of actively excluding the cause of recurrent perianal sepsis, particularly in syndromes where sepsis is a common complication.

    Currarino Syndrome (CS) is a rare congenital malformation characterized by three major clinical aspects: sacral anomalies, anorectal malformation and presacral mass. In familial settings the disorder is transmitted as autosomal dominant trait, with a wide phenotype variability and low penetrance. The causative gene of CS is the motor neuron and pancreas homeobox-1 (MNX1), mapped at 7q36, and coding for a transcription factor. Mutations in the MNX1 have been implicated in almost all familial but only in 30% of sporadic cases. In our cohort of 28 CS cases, 8 were familiar, 18 were sporadic and 2 were not determined cases. We performed mutational analysis of MNX1 in all cases by DNA sequencing as well as by Multiplex Ligation-dependent Probe Amplification (MLPA) in those CS cases where no MNX1 mutations were found, to exclude a MNX1 heterozygous loss. We identified 10 novel and 4 recurrent mutations. Among the novel mutations, 2 were frameshift variants (p.Ser4IlefsX52, p.Phe248SerfsX35), 6 were missense variants (p.Pro27Leu, p.Gly103Arg, p.Leu254Pro, p.Leu278Pro, p.Glu282Lys, p.Arg292Gly), one was a non-sense variant (p.Lys297X), and the last one was a synonymous variant (p.Gln290Gln). Mutated patients showed a variability of phenotypes but all share at least the association of sacral agenesis and presacral mass, and this co-occurrence can constitute a pathognomonic sign to perform MNX1 analysis. Genetic heterogeneity could be a possible explanation for some of the sporadic not mutated patients even if a mis-diagnosis could not be excluded. Finally, we provide an up-date of the more recent literature, reporting a total number of 82 MNX1-CS related mutations.

    2016-01-01

    Full Text Available We report a case of a 14-month-old girl with undiagnosed Currarino triad presenting acutely with meningitis caused by enteric commensals. Head CT demonstrated a large pneumocephalus. A fistulous neurenteric tract through a presacral mass was present on spine MRI and abdominal CT. The patient had a history of constipation for the last three months. However, an underlying diagnosis of Currarino triad had not been suspected. In retrospect, a sickle-shaped sacral anomaly was present on a previous abdominal radiograph. The patient succumbed to complications of meningitis. The purpose of the case report is to highlight the potentially fatal complication of Currarino triad and sensitize radiologists to look actively for sacral anomalies on abdominal radiographs, especially of children with chronic constipation.

    Patau syndrome has an incidence of 1/10.000-20.000, the clinical diagnosis being suggested by the triad cleft lip and palate, microphthalmia/anophthalmia and postaxial polydactyly. Most frequent cytogenetic abnormality is free and homogeneous trisomy 13 (80.0%), rarely being detected trisomy mosaics or Robertsonian translocations. The objective of the study was to identify phenotypic features of trisomy 13. The retrospective study was conducted on a trial group of 14 cases diagnosed cytogenetically with trisomy 13 between January 2000 and December 2012 at lasi Medical Genetics Centre. Of the 14 cases, 3 were evaluated pathologically (two aborted foetuses and one stillborn), 8 cases were detected in the neonatal period, and 3 in infancy. Clinical diagnosis was supported by the identification of a model of abnormal development, mainly characterized by: maxillary cleft (lip and palate--5 cases; lip--1 case), ocular abnormalities (microphthalmia/anophthalmia--7 cases; cyclopia--1 case), postaxial polydactyly (7 cases), scalp defects (6 cases), congenital heart anomalies (10 cases, 6 patients with atrial septal defect), complete holoprosencephaly (4 cases), ear abnormalities (11 cases), broad nasal root (10 cases). An important issue in confirming the phenotypic variability of Patau syndrome is that the classic clinical triad was identified only in one case. Patau syndrome is a disease with variable expression and is characterized by a pattern of abnormal prenatal development characterized by facial dysmorphia, polydactyly and severe birth defects (heart, brain) that generate an increased in utero and perinatal mortality.

    Conclusion: Currarino syndrome is known to be an autosomal dominant disorder. The presence of constipation can lead to a diagnosis of the syndrome early in childhood. In sporadic cases diagnosis is late because of atypical symptoms. Delayed treatment of a presacral tumor may cause serious complications such as central nervous system infection or subsequent neurological dysfunction. In clinical practice, a presacral tumor with a sacral bony defect may indicate Currarino syndrome. Genetic analysis of the family may provide information on the hereditary traits of specific MNX1 mutation.

    1990-02-01

    Here we report on two sibs with Carpenter syndrome showing marked intrafamilial variability. One patient had craniosynostosis of the sagittal suture, normal intelligence, and no abnormalities of hands and feet. The second patient had polysyndactyly of hands and feet, normal intelligence, and no craniosynostosis. The diagnosis of Carpenter syndrome was made after the second affected child in the family was born. This report emphasizes previous suggestions that acrocephalopolysyndactyly, type II, has variable clinical expression. It is suggested that polysyndactyly of feet is not an absolute requisite for the diagnosis of Carpenter syndrome. This allows the inclusion of Summitt and Goodman syndromes within the clinical spectrum of this disorder.

    Sweet\\'s syndrome (SS), a rare reactive neutrophilic dermatosis, has been reported to occur in association with a variety of systemic disorders, categorized by von den Diesch into idiopathic, paraneoplastic, pregnancy and parainflammatory subgroups. The parainflammatory group has been well defined, and includes a wide spectrum of infectious triggers and disorders of immune dysregulation. To date, however, no cases of SS have been described in the context of common variable immunodeficiency (CVID). We report a case of paediatric-onset SS, previously reported as idiopathic, with a subsequent diagnosis of CVID.

    Joubert syndrome (JS) is an autosomal recessive inherited disorder characterized by hypotonia, cerebellar vermis hypoplasia, ocular abnormalities (e.g. pigmentary retinopathy, oculomotor apraxia and nystagmus), renal cysts and hepatic fibrosis. Respiratory abnormalities, as apnoea and hyperpnoea, may be present, as well as mental retardation. At least seven JS loci have been determined and five genes identified. Herein, we report five children, belonging to independent families, with JS: they shared the same typical MRI abnormality, known as molar tooth sign, but had an otherwise quite variable phenotype, regarding mostly their cognitive performance, visual abilities and extra-neurological compromise.

    Multiple studies have tried to establish the distinctive profile of individuals with Asperger's syndrome (AS). However, recent reports suggest that adults with AS feature heterogeneous cognitive profiles. The present study explores inter-individual variability in children with AS through group comparison and multiple case series analysis. All participants completed an extended battery including measures of fluid and crystallized intelligence, executive functions, theory of mind, and classical neuropsychological tests. Significant group differences were found in theory of mind and other domains related to global information processing. However, the AS group showed high inter-individual variability (both sub- and supra-normal performance) on most cognitive tasks. Furthermore, high fluid intelligence correlated with less general cognitive impairment, high cognitive flexibility, and speed of motor processing. In light of these findings, we propose that children with AS are characterized by a distinct, uneven pattern of cognitive strengths and weaknesses.

We describe here the phenotypic and behavioral variability detected in eight UPD patients out of a group of 58 AS patients studied. All of them presented developmental delay, mental retardation, ataxia, speech impairment, and frequent drooling. Only one had microcephaly, whereas in two of them the OFC (head circumference was above the 98th percentile. The weight of all patients was above the 50th percentile, and in three of them the height was above the 90th percentile. Three were able to say a few words and to communicate by gestures. Two patients presented hyperphagia, and three presented skin picking, common features in the Prader-Willi syndrome (PWS. Four patients (4/7 had wide-spaced teeth. Five presented seizures, and two others did not manifest frequent laughter. One patient was very different from the others, as he showed a better understanding and abilities to communicate, to play video games and to draw. We suggest here that there seems to be an extreme phenotypic and behavioral variability within the UPD group, and that both typical patients and those with mental retardation, language impairment, happy disposition, and hyperactivity should be tested for AS.

    2014-11-01

    A number of cross-sectional studies have examined associations between heart rate variability and metabolic syndrome, but differences in study populations, data collection and analysis methodologies make synthesis difficult. The purpose of this study was to systematically review published primary research examining associations between heart rate variability and metabolic syndrome or its individual risk factors. A systematic literature search of PubMed and EMBASE was conducted to identify relevant articles published from January 1999 to December 2012. Studies were included if they examined associations between heart rate variability analysed by standard protocols and metabolic syndrome risk factors according to published definitions. All papers were scored with a modified Downs and Black instrument, and data were extracted. Fourteen studies were included. Heart rate variability generally was reduced in women with metabolic syndrome compared to those without, while results in men were inconsistent. Time and frequency domain heart rate variability parameters were associated with individual metabolic syndrome risk factors, though sex differences exist. Only two studies considered nonlinear and Poincaré plot heart rate variability parameters, which were reduced in metabolic syndrome. Heart rate variability is altered differently in men and women with metabolic syndrome. Future studies should follow consistent heart rate variability analysis protocols and metabolic syndrome definitions and include more comprehensive analyses to investigate potential mechanisms.

    Down syndrome (DS) is associated with ocular and cognitive sequelae, which both have the potential to influence clinical measures of refractive error. This study compares variability of autorefraction among subjects with and without DS. Grand Seiko autorefraction was performed on 139 subjects with DS (age: 8-55, mean: 25 ± 9 yrs) and 138 controls (age: 7-59, mean: 25 ± 10 yrs). Subjects with three refraction measures per eye (DS: 113, control: 136) were included for analysis. Each refraction was converted to power vector notation (M, J0, J45) and a difference in each component (ΔM, ΔJ0, ΔJ45) was calculated for each refraction pairing. From these quantities, average dioptric strength ((Equation is included in full-text article.): square root of the sum of the squares of M, J0, and J45) and average dioptric difference ((Equation is included in full-text article.): square root of the sum of the squares of ΔM, ΔJ0, and ΔJ45) were calculated. The DS group exhibited a greater median (Equation is included in full-text article.)(1Q: 1.38D M: 2.38D 3Q: 3.41D) than control eyes (1Q: 0.47D M: 0.96D 3Q: 2.75D) (P refraction (1Q: 0.27D M: 0.42D 3Q: 0.78D) than control eyes (1Q: 0.11D M: 0.15D 3Q: 0.23D) (P refraction for this population. The analysis demonstrates that J45 is highly contributory to the observed variability.

    Adenocorticotropic hormone (ACTH)-dependent Cushing's syndrome in infancy is extremely rare. We describe the case of a sacro-coccygeal ectopic ACTH-secreting immature teratoma in an infant who also presented the triad of defects characteristic of Currarino syndrome. A girl was born with a large immature teratoma in the sacro-coccygeal region associated with anal atresia. At the age of 7 days, the concentration of α-fetoprotein (AFP) was above the age-specific normal range. Two non-radical surgical excisions of the tumour were performed. At the age of 7 months, she developed polyphagia, acne, hirsutism, hypertension and hypokalemia with elevated ACTH and absence of serum cortisol circadian rhythm. Immunostaining of tumour tissue showed ACTH-immunoreactive cells. Due to unsuccessful therapy with ketoconazole and resistance to antihypertensive medications [blood pressure (BP) 210/160 mmHg], metyrapone was administered, which controlled her ACTH and cortisol levels in the normal range. Following further removal of tumour bulk after three operations during the first year of life, there was a decrease of BP to normal values. A rare case of ectopic ACTH syndrome causing Cushing's syndrome in infancy in the context of Currarino syndrome is reported. Radical surgery has resulted in excision of the tumour and current control of Cushing's syndrome.

    Connexins belong to the family of gap junction proteins which enable direct cell-to-cell communication by forming channels in adjacent cells. Mutations in connexin genes cause a variety of human diseases and, in a few cases, result in skin disorders. There are significant differences in the clinical picture of two rare autosomal dominant syndromes: keratitis-ichthyosis-deafness (KID) syndrome and hidrotic ectodermal dysplasia (Clouston syndrome), which are caused by GJB2 and GJB6 mutations, respectively. This is despite the fact that, in both cases, malfunctioning of the same family proteins and some overlapping clinical features (nail dystrophy, hair loss, and palmoplantar keratoderma) is observed. KID syndrome is characterized by progressive vascularizing keratitis, ichthyosiform erythrokeratoderma, and neurosensory hearing loss, whereas Clouston syndrome is characterized by nail dystrophy, hypotrichosis, and palmoplantar keratoderma. The present paper presents a Polish patient with sporadic KID syndrome caused by the mutation of p.Asp50Asn in GJB2. The patient encountered difficulties in obtaining a correct diagnosis. The other case presented is that of a family with Clouston syndrome (caused by p.Gly11Arg mutation in GJB6), who are the first reported patients of Polish origin suffering from this disorder. Phenotype diversity among patients with the same genotypes reported to date is also summarized. The conclusion is that proper diagnosis of these syndromes is still challenging and should always be followed by molecular verification.

    Robinow syndrome comprises dysmorphic facial features, short stature, brachymesomelia, segmental spine defects, and genital hypoplasia. The range of severity in this disorder is broad. We report on the clinical and molecular findings of two sib pairs from the same extended family with Robinow syndrome due to a novel intragenic ROR2 deletion involving exons 6 and 7 that could not be detected by sequencing. The affected individuals exhibited variability with respect to the cleft lip, cleft palate, and cardiac findings and for the presence in one of the patients of syringomyelia, which has not been previously reported in Robinow syndrome.

    2005-09-01

    We investigated the effect of a high walnut and cashew diet on haemostatic variables in people with the metabolic syndrome. Factor analysis was used to determine how the haemostatic variables cluster with other components of the metabolic syndrome and multiple regression to determine possible predictors. This randomized, control, parallel, controlled-feeding trial included 68 subjects who complied with the Third National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol criteria. After a 3-week run-in following the control diet, subjects were divided into three groups receiving either walnuts or cashews (20 energy%) or a control diet for 8 weeks. The nut intervention had no significant effect on von Willebrand factor antigen, fibrinogen, factor VII coagulant activity, plasminogen activator inhibitor 1 activity, tissue plasminogen activator activity or thrombin activatable fibrinolysis inhibitor. Statistically, fibrinogen clustered with the body-mass-correlates and acute phase response factors, and factor VII coagulant activity clustered with high-density lipoprotein cholesterol (HDL-C). Tissue plasminogen activator activity, plasminogen activator inhibitor 1 activity and von Willebrand factor antigen clustered into a separate endothelial function factor. HDL-C and markers of obesity were the strongest predictors of the haemostatic variables. We conclude that high walnut and cashew diets did not influence haemostatic factors in this group of metabolic syndrome subjects. The HDL-C increase and weight loss may be the main focus of dietary intervention for the metabolic syndrome. Furthermore, diet composition may have only limited effects if weight loss is not achieved.

  20. Exertion and pain do not alter coordination variability in runners with iliotibial band syndrome.

    Hafer, Jocelyn F; Brown, Allison M; Boyer, Katherine A

    2017-08-01

    Iliotibial band syndrome is a common overuse running injury which results in altered mechanics. While injuries alter discrete mechanics, they may also cause a change in coordination variability, the stride-to-stride organization of runners' movement patterns. Uninjured and injured runners may experience a change in coordination variability during a run to exertion due to fatigue, pain, or a combination of these factors. The aim of the current study was to determine if runners with iliotibial band syndrome and uninjured runners display different segment coordination variability across the course of a run to exertion. 3D kinematics were collected as 13 uninjured runners and 12 runners with iliotibial band syndrome ran on a treadmill. A modified vector coding technique was used to calculate coordination variability during stance for segment couples of interest. Coordination variability was compared between uninjured and injured runners at the beginning and end of the run. The influence of pain on coordination variability was also examined. There were no differences in coordination variability at the beginning or end of the run between uninjured runners and those with iliotibial band syndrome. The change in coordination variability due to the run was not different between uninjured runners, injured runners who experienced no change in pain, and injured runners who did experience a change in pain. Runners do not constrain the patterns of segment motion they use in response to exertion nor does it appear that occurrence of pain during running results in a differential change in coordination variability.

    1977-12-01

    A family is described in which 15 persons in five generations are affected with a complex of skeletal malformations which variably includes peculiar asymmetric facies, delayed closure of large fontanels, brachycephaly, acrocephaly, brachydactyly, cutaneous syndactyly, broad great toes, and mild shortness of stature. Although craniosynostosis is either lacking or relatively mild in the members of this family, their features are otherwise strikingly similar to those of patients with the Saethre-Chotzen syndrome. We believe the findings in this family indicate that the Saethre-Chotzen syndrome comprises a broad pattern of carniofacial and other skeletal malformations in which craniosynostosis may sometimes occur.

    Full Text Available Diarrhea is one of the most common symptoms in common variable immunodeficiency, but neurologic manifestations are rare. We presented a 50-year-old woman with recurrent diarrhea and severe weight loss that developed a posterior cord syndrome. Endoscopy found a duodenal villous blunting, intraepithelial lymphocytosis, and lack of plasma cells and magnetic resonance imaging of the spine was normal. Laboratory assays confirmed common variable immunodeficiency syndrome and showed low levels of trace elements (copper and zinc. Treatment was initiated with parenteral replacement of trace elements and intravenous human immunoglobulin and the patient improved clinically. In conclusion, physicians must be aware that gastrointestinal and neurologic disorders may be related to each other and remember to request trace elements laboratory assessment.

    2013-09-01

    Polycystic ovary syndrome (PCOS) is an endocrine disorder associated with several cardiometabolic risk factors, such as central obesity, insulin resistance, type 2 diabetes, metabolic syndrome, and hypertension. These factors are associated with adrenergic overactivity, which is an important prognostic factor for the development of cardiovascular disorders. Given the common cardiometabolic disturbances occurring in PCOS women, over the last years studies have investigated the cardiac autonomic control of these patients, mainly based on heart rate variability (HRV). Thus, in this review, we will discuss the recent findings of the studies that investigated the HRV of women with PCOS, as well as noninvasive methods of analysis of autonomic control starting from basic indexes related to this methodology.

    2015-01-01

    Dominant optic atrophy (DOA) and Wolfram syndrome share a great deal of clinical variability, including an association with hearing loss and the presence of optic atrophy at similar ages. The objective of this paper was to discuss the phenotypic variability of these syndromes with respect to the presentation of two clinical cases. We present two patients, each with either DOA or Wolfram syndrome, and contribute to the research literature through our findings of two novel mutations. The overlapping of several clinical characteristics in hereditary optic neuropathies can complicate the differential diagnosis. Future studies are needed to better determine the genotype-phenotype correlation for these diseases.

    The transmission of hemorrhagic fever with renal syndrome (HFRS) is influenced by climatic variables. However, few studies have examined the quantitative relationship between climate variation and HFRS transmission. We examined the potential impact of climate variability on HFRS transmission and developed climate-based forecasting models for HFRS in northeastern China. We obtained data on monthly counts of reported HFRS cases in Elunchun and Molidawahaner counties for 1997-2007 from the Inner Mongolia Center for Disease Control and Prevention and climate data from the Chinese Bureau of Meteorology. Cross-correlations assessed crude associations between climate variables, including rainfall, land surface temperature (LST), relative humidity (RH), and the multivariate El Niño Southern Oscillation (ENSO) index (MEI) and monthly HFRS cases over a range of lags. We used time-series Poisson regression models to examine the independent contribution of climatic variables to HFRS transmission. Cross-correlation analyses showed that rainfall, LST, RH, and MEI were significantly associated with monthly HFRS cases with lags of 3-5 months in both study areas. The results of Poisson regression indicated that after controlling for the autocorrelation, seasonality, and long-term trend, rainfall, LST, RH, and MEI with lags of 3-5 months were associated with HFRS in both study areas. The final model had good accuracy in forecasting the occurrence of HFRS. Climate variability plays a significant role in HFRS transmission in northeastern China. The model developed in this study has implications for HFRS control and prevention.

    Gait is one of the most frequently impaired bodily functions in multiple sclerosis (MS). Determining abnormal parameters of gait in early MS could influence MS treatment and rehabilitation. The purpose of this study was to determine whether increased step-length variability could be detected in minimally disabled patients with MS or clinically isolated syndrome (CIS) using a sensored walkway gait analysis system. Nine participants with MS/CIS and nine age- and gender-matched controls were recruited for this study. MS/CIS participants underwent a neurologic examination, and all participants completed a screening interview. Each participant completed three walks at a self-selected pace and three walks at a brisk pace across the GAITRite walkway (MAP/CIR Inc, Havertown, PA). Mean values for step-length variability, step length, and velocity were calculated for each participant's self-selected and brisk trials. Independent t tests were used to compare MS/CIS participants with controls, and effect sizes were calculated. Step-length variability in the left leg at the self-selected pace was found to be greater in participants with MS/CIS than in controls, although no significant differences were found in velocity or step length. Step-length variability measurement shows promise in detecting subtle gait dysfunction. Larger, prospective studies exploring step-length variability may determine its clinical viability for detecting subtle gait dysfunction and could lead to improved prognostication of disability progression in MS.

    2014-07-01

    Full Text Available Multiple studies have tried to establish the distinctive profile of individuals with Asperger’s syndrome (AS. However, recent reports suggest that adults with AS feature heterogeneous cognitive profiles. The present study explores inter-individual variability in children with AS through group comparison and multiple case series analysis. All participants completed an extended battery including measures of fluid and crystallized intelligence, executive functions, theory of mind, and classical neuropsychological tests. Significant group differences were found in theory of mind and other domains related to global information processing. However, the AS group showed high inter-individual variability (both sub- and supra-normal performance on most cognitive tasks. Furthermore, high fluid intelligence correlated with less general cognitive impairment, high cognitive flexibility, and speed motor processing. In light of these findings, we propose that children with AS are characterized by a distinct, uneven pattern of cognitive strengths and weaknesses.

  19. Memory for Fatigue in Chronic Fatigue Syndrome: Relationships to Fatigue Variability, Catastrophizing, and Negative Affect

    Sohl, Stephanie J.; Friedberg, Fred

    2008-01-01

    Fatigue in chronic fatigue syndrome (CFS) is usually assessed with retrospective measures rather than real-time momentary symptom assessments. In this study, the authors hypothesized that in participants with CFS, discrepancies between recalled and momentary fatigue would be related to catastrophizing, anxiety, and depression and to variability of momentary fatigue. They also expected that catastrophizing, anxiety, and depression would be associated with momentary fatigue. The authors asked 53 adults with CFS to carry electronic diaries for 3 weeks and record their experiences of momentary fatigue. The authors assessed participants' fatigue recall with weekly ratings and administered questionnaires for catastrophizing, depression, and anxiety. Recall discrepancy was significantly related to the variability of momentary fatigue. In addition, catastrophizing, depression, and momentary fatigue were all significantly related to recall discrepancy. Catastrophizing, depression, anxiety, and momentary negative affect were all significantly associated with momentary fatigue. The findings suggest that momentary fatigue in patients with CFS is related to modifiable psychological factors. PMID:18400687

    We investigated how the diagnosis of postural orthostatic tachycardia syndrome (POTS) would be changed due to diurnal variability in orthostatic tachycardia. The orthostatic vital sign test was administered to each patient twice, in the afternoon of the day of admission and the next morning (n = 113). Forty-six patients were diagnosed with POTS, and the remaining 67 patients were assigned to non-POTS group. Heart rate increments after standing were larger in the morning than in the afternoon in every group (all P orthostatic vital sign test. Orthostatic intolerance symptoms were provoked in only 45.7% of the POTS patients, more frequently in the morning. In conclusion, diurnal variability in hemodynamic parameters and provoked symptoms significantly challenged the diagnosis of POTS.

    Patients with POTS (postural tachycardia syndrome) have excessive orthostatic tachycardia (>30 beats/min) when standing from a supine position. HR (heart rate) and BP (blood pressure) are known to exhibit diurnal variability, but the role of diurnal variability in orthostatic changes of HR and BP is not known. In the present study, we tested the hypothesis that there is diurnal variation of orthostatic HR and BP in patients with POTS and healthy controls. Patients with POTS (n=54) and healthy volunteers (n=26) were admitted to the Clinical Research Center. Supine and standing (5 min) HR and BP were obtained in the evening on the day of admission and in the following morning. Overall, standing HR was significantly higher in the morning (102±3 beats/min) than in the evening (93±2 beats/min; Porthostatic BP in POTS. A greater number of subjects met the POTS HR criterion in the morning compared with the evening (P=0.008). There was significant diurnal variability in orthostatic tachycardia, with a great orthostatic tachycardia in the morning compared with the evening in both patients with POTS and healthy subjects. Given the importance of orthostatic tachycardia in diagnosing POTS, this diurnal variability should be considered in the clinic as it may affect the diagnosis of POTS.

    Full Text Available Background:The risk factors that characterize metabolic syndrome (MetS may be present in childhood and adolescence, increasing the risk of cardiovascular disease in adulthood.Objective:Evaluate the prevalence of MetS and the importance of its associated variables, including insulin resistance (IR, in children and adolescents in the city of Guabiruba-SC, Brazil.Methods:Cross-sectional study with 1011 students (6–14 years, 52.4% girls, 58.5% children. Blood samples were collected for measurement of biochemical parameters by routine laboratory methods. IR was estimated by the HOMA-IR index, and weight, height, waist circumference and blood pressure were determined. Multivariate logistic regression models were used to examine the associations between risk variables and MetS.Results:The prevalence of MetS, IR, overweight and obesity in the cohort were 14%, 8.5%, 21% and 13%, respectively. Among students with MetS, 27% had IR, 33% were overweight, 45.5% were obese and 22% were eutrophic. IR was more common in overweight (48% and obese (41% students when compared with eutrophic individuals (11%; p = 0.034. The variables with greatest influence on the development of MetS were obesity (OR = 32.7, overweight (OR = 6.1, IR (OR = 4.4; p ≤ 0.0001 for all and age (OR = 1.15; p = 0.014.Conclusion:There was a high prevalence of MetS in children and adolescents evaluated in this study. Students who were obese, overweight or insulin resistant had higher chances of developing the syndrome.

    Full Text Available Objectives: The present retrospective study analyzes sagittal cephalometric changes in patients affected by obstructive sleep apnea syndrome submitted to maxillomandubular advancement. Material and Methods: 15 adult sleep apnea syndrome (OSAS patients diagnosed by polysomnography (PSG and treated with maxillomandubular advancement (MMA were included in this study. Pre- (T1 and postsurgical (T2 PSG studies assessing the apnea/hypopnea index (AHI and the lowest oxygen saturation (LSAT level were compared. Lateral cephalometric radiographs at T1 and T2 measuring sagittal cephalometric variables (SNA, SNB, and ANB were analyzed, as were the amount of maxillary and mandibular advancement (Co-A and Co-Pog, the distance from the mandibular plane to the most anterior point of the hyoid bone (Mp-H, and the posterior airway space (PAS.Results: Postoperatively, the overall mean AHI dropped from 58.7 ± 16 to 8.1 ± 7.8 events per hour (P < 0.001. The mean preoperative LSAT increased from 71% preoperatively to 90% after surgery (P < 0.001. All the patients in our study were successfully treated (AHI < 20 or reduced by 50%. Cephalometric analysis performed after surgery showed a statistically significant correlation between the mean SNA variation and the decrease in the AHI (P = 0.01. The overall mean SNA increase was 6°.Conclusions: Our findings suggest that the improvement observed in the respiratory symptoms, namely the apnea/hypopnea episodes, is correlated with the SNA increase after surgery. This finding may help maxillofacial surgeons to establish selective criteria for the surgical approach to sleep apnea syndrome patients.

    Quantitative sensory testing is a reference method for characterization of postsurgical neuropathic components. Correct interpretation of data requires detailed information concerning the validity of the testing methods. The objective of the study was to assess the test-retest variability of thermal thresholds in patients (n = 14) with the postthoracotomy pain syndrome. Sensory mapping with a metal roller (25°C) on the surgical side delineated an area with cool sensory dysfunction. In this area and in a contralateral area, 4 prespecified sites (2.6 cm) were outlined, in addition to the maximum pain site on the surgical side. In these total 9 sites, warmth detection threshold, cool detection threshold, and heat pain threshold were assessed. Comparisons of thermal test-retest assessments did not demonstrate any significant intraside differences. The SDs of the thermal assessments in nonpain sites and in the maximum pain site ranged from 1.9 to 2.5°C and 3.5 to 6.9°C, respectively. The estimated within-patient and between-patient variances were 5% to 28% and 72% to 95%, respectively, of the total variances. Although a generally poor test-retest agreement was demonstrated, the much lower within-patient than between-patient variances facilitated estimations of highly statistical significant, within-patient differences in thermal thresholds. In patients with postthoracotomy pain syndrome, several statistical methods indicated an excessively high variability in thermal thresholds, questioning the use of single quantitative sensory testing in assessments to characterize patients with chronic pain states.

    The aim of this study is to define absolute and relative reliability of spectral indices of cardiovascular autonomic control in the supine position in women with fibromyalgia syndrome (FMS). Twenty-three women with FMS (age 48 ± 7 years) took part in the study. ECG, finger blood pressure, and respiration were continuously recorded in all participants at rest in baseline 1 (BL1) and after 15 days from BL1 (BL2). The power spectrum analysis provided two oscillatory components: low frequency (LF, 0.04-0.15 Hz) and high frequency (HF, 0.15-0.4 Hz) from the heart period (HP) variability and the LF oscillatory component from SAP variability (LFSAP). Absolute and relative reliability were rated by 95 % of the limit of random variation and intraclass correlation coefficient (ICC), respectively. No significant differences were observed between BL1 and BL2 for the spectral indices of HP and SAP variabilities. The 95 % limit of the random variation of these indices indicated that the values of repeated measurements were between 22 % higher and 0.2 % lower (more reliable parameter; average of HP variability) and 912.9 % higher and 0.2 % lower (less reliable parameter; LFSAP) than BL1. Conversely, the index of relative reliability (ICC) ranged from 0.23 to 0.70 indicating a good reliability. The spectral indices of cardiovascular autonomic control in women with FMS seem to present good relative reliability. Therefore, these indices can be useful as parameters to quantify if a variation was consistent and accurate in the retest besides adding crucial information for clinical research and clinical evaluation of FMS patients.

    Common variable immunodeficiency (CVID) represents a large heterogeneous group of antibody-deficiency syndromes associated with a wide range of clinical features and a lack of defined causes in the realm of primary immunodeficiencies. Here, we present a case of CVID in a 62-year-old white male patient with a history of longstanding complex regional pain syndrome (CRPS). His medical history included multiple sinus infections per year and several pneumonias requiring antibiotics. He has had various back surgeries, including a laminectomy at the L4 level 1 year prior to his diagnosis. Thereafter, he underwent four sympathetic nerve blocks with minimal pain relief. Blood chemistries showed a normal white blood cell count with a normal differential, but increased erythrocyte sedimentation rate and C-reactive protein levels. Total Ig (Immunoglobulin)G was 611 mg/dL (normal 700-1,600), IgG1 was 425 mg/dL (341-894), IgG2 was 114 mg/dL (171-632), IgG3 was 14.4 mg/dL (18.4-106), and IgG4 was 7.4 mg/dL (2.4-121). IgA was 47 mg/dL (normal 70-400), IgM was 131 mg/dL (40-230), and IgE was 4.5 kU/L (<4.0). He only had 10 of 23 pneumococcal titers in the protective range post-vaccination. Upon treatment of the CVID with intravenous immunoglobulin, the patient's pain levels were significantly decreased and have been maintained for more than 2 years. Therefore, immunoglobulin therapy appears to have been beneficial in the treatment of the patient's symptoms of CRPS, including pain. Additional studies investigating the mechanism by which immunoglobulin therapy may reduce the inflammation and pain of CRPS are needed.

    Full Text Available INTRODUCTION: Metabolic syndrome (MetS is described as a group of various abnormal metabolic risk factors such as obesity, dyslipidemia, increased blood pressure, increased plasma glucose levels, prothrombotic condition and proinflammatory state. These parameters are related to decreased parasympathetic and increased sympathetic activity. We aimed to evaluate autonomic function using a combination with heart rate variability (HRV and heart rate turbulence (HRT in metabolic syndrome to compare non-metabolic syndrome(non-MetS. METHODS: We selected consecutive 50 patients with MetS and 50 patients with healthy non-MetS individuals. All patients underwent 24 hours holter monitoring to evaluate HRT and HRV parameters. RESULTS: Age of patients was not different in two groups. Mean age of MetS patients was 57,50±12,13 and 54,6±10,25 in non- MetS individuals. Sex of patients was non different in MetS compared to non-MetS (37 female and 13 male vs. 22 female, 28 male p<0,05 respectively. SDNN and RMSSD was lower in MetS compared to those without MetS (131,96±49,12 vs 179,59±85,83 p=0,03 and 78,64±35,22 vs 112,73±81,24 p=0,08 respectively. SDANN, pNN50,Mean RR, mean heart rate, count of ventricular premature complex(VPC were not different between two groups. Turbulence Slope(TS was not different in two groups. Turbulence Onset(TO was higher in MetS compared to non-MetS (2,01±15,29 and -6,21±13,5 p=0,005. DISCUSSION AND CONCLUSION: We showed that autonomic function in MetS was impaired using a combination with HRT and HRV. These patients should be followed closely for adverse cardiovascular outcome especially including cardiac arrhythmia.

    Much of what is known about the cognitive profile of Down syndrome (DS) is based on using either receptive vocabulary (e.g., PPTV-4) or nonverbal ability (e.g., Leiter-R) as a baseline to represent cognitive developmental level. In the present study, we examined the relation between these two measures in youth with DS, with non-DS intellectual disability (ID), and with typical development (TD). We also examined the degree to which these two measures produce similar results when used as a group matching variable. In a cross-sectional developmental trajectory analysis, we found that the relation between PPVT-4 and Leiter-R was largely similar across groups. However, when contrasting PPVT-4 and Leiter-R as alternate matching variables, the pattern of results was not always the same. When matched on Leiter-R or PPVT-4, the group with DS performed below that of the groups with ID and TD on receptive grammar and below the group with TD on category learning. When matched on the PPVT-4, the group with ID performed below that of the group with TD on receptive grammar and category learning, but these differences between the groups with ID and TD were not found when matched on the Leiter-R. The results of the study suggest that the PPVT-4 and Leiter-R are interchangeable at least for some outcome measures for comparing youth with DS and TD, but they may produce different results when comparing youth with ID and TD.

    Long QT syndrome (LQTS) is a primary electrical disease characterized by QT prolongation and increased repolarization dispersion leading to T-wave amplitude beat-to-beat changes. We aimed to quantify beat-to-beat T-wave amplitude variability from ambulatory Holter recordings in genotyped LQTS patients. Seventy genotyped LQTS patients (mean age 23 +/- 15 years, 42 males, 50% LQT1, 39% LQT2, and 11% LQT3) and 70 normal matched control subjects underwent a 24-h digital Holter recording. Using the Tvar software (Ela Medical, Sorin group), the beat-to-beat variance of the T-wave amplitude (TAV in microV) [corrected] was assessed on 50-ms consecutive clusters during three 1-h periods: one with around average diurnal heart rate (Day Fast), one nocturnal period (Night), and one diurnal period with around average nocturnal heart rate (Day Slow). TAV was increased in LQTS patients during the two diurnal periods but not at night (during the Day Fast period, mean TAV was 34 +/- 20 microV [corrected] in LQTS patients vs. 27 +/- 10 microV [corrected] in controls, P < 0.05). This effect depended on the genotype. In LQT1, TAV was larger when compared with controls for both Day Fast and Slow periods, but in LQT2 only Day Fast shows higher TAV. Oppositely, in LQT3 the TAV was higher than in the control group during the Day slow period (mean TAV = 34 +/- 20 vs. 25 +/- 8 microV [corrected] in controls, P < 0.05). In genotyped LQTS patients beat-to-beat T-wave amplitude variability was increased when compared with control subjects. That pattern was modulated by circadian influences in a gene-dependent manner.

    Full Text Available A 1-year-old girl born to consanguineous parents presented with unexplained liver failure, leading to transplantation at 19 months. Subsequent partial splenectomy for persistent cytopenia showed the presence of foamy cells, and Gaucher disease was confirmed by homozygosity for the p.Leu483Pro mutation in the GBA gene. She was treated by enzyme replacement therapy (ERT. Clinical follow-up showed mild developmental delay, strabismus, nystagmus and oculomotor apraxia. Biochemical studies revealed multiple respiratory chain deficiencies and a mosaic pattern of deficient complex IV immunostaining in liver and fibroblast. Molecular analysis identified a mtDNA depletion syndrome due to the homozygous p.Pro98Leu mutation in MPV17. A younger sister unaffected by mtDNA depletion, presented with pancytopenia and hepatosplenomegaly. ERT for Gaucher disease resulted in visceral normalization without any neurological symptom. A third sister, affected by both conditions, had marked developmental delay, strabismus and ophthalmoplegia but no liver cirrhosis. In conclusion, intrafamilal variability occurs in MPV17-related disease. The combined pathological effect of Gaucher and mitochondrial diseases can negatively impact neurological and liver functions and influence the outcome in consanguineous families. The immunocytochemical staining of OXPHOS protein in tissues and cultured cells is a powerful tool revealing mosaic pattern of deficiency pointing to mtDNA-related mitochondrial disorders.

    The burnout syndrome is a set of work-related symptoms related to weariness and exhaustion, in response to the emotional stress at work and its consequences. The aim of the study was to measure the frequency of burnout in General Practitioners (GPs) from 3 private institutions in Bogotá, Colombia and to determine the associated factors according to the variables taken into account. It is a descriptive cross-sectional study which was used to analyse the Questionnaire for Burnout Syndrome (CESQT). The population was 106 GPs. The level of burnout was at a critical level in 6.6% of the GP population. The variables showed that having a stable partner and children are a protective factor. By contrast, work in emergency rooms is a risk factor. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

Female patients (n=291 with a firm RA diagnosis under 60 years of age were examined. Evaluation of traditional cardiovascular risk factors, MS components (International Diabetes Federation criteria, 24-hour ECG monitoring were performed along with the assessment of clinical symptoms, the degree of activity and severity of RA.Results. Weak associations of HRV with waist circumference, blood pressure level, hypertriglyceridemia, hypoalphalipoproteinemia and smoking were found in the correlation analysis. Patients with RA were divided into three groups depending on the number of existing MS components. Group 1 (0-1 component included 113 women (39%, group 2 (2-3 components – 109 women (37% and group 3 (4-5 components – included 69 women with RA (24%. Progressive decrease in the absolute values and the increase in the percentage of the low values of all the studied time and frequency HRV indices, adjusted by age and heart rate, from the 1st to the 3rd group of women with RA were determined. Significant increase in sympathovagal index from the 1st to the 3rd group was also shown.Conclusion. A combination of several components of the MS in RA plays a greater role in the development of disorders of neurovegetative autonomic control of heart activity (increased influence of the sympathetic and/or reduced influence of the parasympathetic nervous system on cardiac function than each traditional cardiovascular risk factor taken separately. Abnormality in autonomic regulation of cardiac activity may be an important link in the pathogenesis of cardiac arrhythmias, sudden cardiac death and overall cardiovascular mortality in women with RA.

    Full Text Available CONTEXT (BACKGROUND: Polycystic ovary syndrome (PCOS is one of the most common endocrinopathy of premenopausal women and is a most frequent cause of infertility. There are more stringent reports of cardiovascular events and infrequent investigations of lipid levels in lean PCOS. AIMS: To assess the cardiac autonomicity using Heart Rate Variability (HRV parameters and metabolic risk with serum lipid parameters among ideal and lean weight PCOS patients. Settings and Design: case control study. 24 classical PCOS diagnosed by Rotterdam 2003 Diagnostic criteria and were ideal and lean as per WHO criter ia and 24 BMI matched, age matched normally menstruating women served as study participants. Methods and Material: 5 min of Electrocar - diogram (ECG was taken which was evaluated for HRV. Power spectral analysis was done to calculate the time and frequency domain measures of HRV. Fasting serum lipid profile was done. Statistical analysis: Independent sample‘t’ test was used. RESULTS: The results of the present study showed that cardiac autonomic innervations can be affected in lean and ideal weight PCOS wit h increased sympathetic and decreased parasympathetic components of HRV. As a result, sympathetic to parasympathetic ratio may increase in PCOS. Fasting blood sugar was also increased. Of the lipid parameters total cholesterol and LDL - C was increased. Othe r parameters were not altered. CONCLUSION: This study gives a solid and strong evidence of altered cardiac autonomic activity and unfavorable metabolic profile, which are the important risk factors for cardiovascular disease even in lean and ideal weight P COS. Our data suggest that all PCOS patients should undergo periodic screening for normal cardiac activity and lipid profiles irrespective of obesity.

    Heart rate variability (HRV) reflects the healthiness of autonomic nervous system, which is associated with exercise capacity. We therefore investigated whether HRV could predict the exercise capacity in the adults with cardiac syndrome X (CSX). A total of 238 subjects (57±12 years, 67.8% men), who were diagnosed as CSX by the positive exercise stress test and nearly normal coronary angiogram were enrolled. Power spectrum from the 24-hour recording of heart rate was analyzed in frequency domain using total power (TP) and spectral components of the very low frequency (VLF), low frequency (LF) and high frequency (HF) ranges. Among the study population, 129 subjects with impaired exercise capacity during the treadmill test had significantly lower HRV indices than those with preserved exercise capacity (≥90% of the age predicted maximal heart rate). After accounting for age, sex, and baseline SBP and heart rate, VLF (odds ratio per 1SD and 95% CI: 2.02, 1.19-3.42), LF (1.67, 1.10-2.55), and TP (1.82, 1.17-2.83) remained significantly associated with preserved exercise capacity. In addition, increased HRV indices were also associated with increased exercise duration, rate-pressure product, and heart rate recovery, independent of age, body mass index, and baseline SBP and heart rate. In subgroup analysis, HRV indices demonstrated similar predictive values related to exercise capacity across various subpopulations, especially in the young. In patients with CSX, HRV was independently associated with exercise capacity, especially in young subjects. The healthiness of autonomic nervous system may have a role in modulating the exercise capacity in patients with CSX.

    Previous research has proposed that a lack of variability in lower extremity coupling during running is associated with pathology. The purpose of the study was to evaluate lower extremity coupling variability in runners with and without a history of iliotibial band syndrome (ITBS) during an exhaustive run. Sixteen runners ran to voluntary exhaustion on a motorized treadmill while a motion capture system recorded reflective marker locations. Eight runners had a history of ITBS. At the start and end of the run, continuous relative phase (CRP) angles and CRP variability between strides were calculated for key lower extremity kinematic couplings. The ITBS runners demonstrated less CRP variability than controls in several couplings between segments that have been associated with knee pain and ITBS symptoms, including tibia rotation-rearfoot motion and rearfoot motion-thigh ad/abduction, but more variability in knee flexion/extension-foot ad/abduction. The ITBS runners also demonstrated low variability at heel strike in coupling between rearfoot motion-tibia rotation. The results suggest that runners prone to ITBS use abnormal segmental coordination patterns, particular in couplings involving thigh ad/abduction and tibia internal/external rotation. Implications for variability in injury etiology are suggested.

  1. Lyapunov Exponent and Surrogation Analysis of Patterns of Variability: Profiles in New Walkers With and Without Down Syndrome

    Smith, Beth A.; Stergiou, Nicholas; Ulrich, Beverly D.

    2010-01-01

    In previous studies we found that while preadolescents with Down syndrome (DS) produce higher amounts of variability (Smith et al., 2007) and larger Lyapunov exponent (LyE) values (indicating more instability) during walking than peers with typical development (TD) (Buzzi & Ulrich, 2004), they also partition more of this into goal-equivalent variability (UCM//), that can be exploited to increase options for success when perturbed (Black et al., 2007). Here we use nonlinear methods to examine the patterns that characterize gait variability as it emerges, in toddlers with TD and with DS, rather than after years of practice. We calculated Lyapunov exponent (LyE) values to assess stability of leg trajectories. We also tested the use of 3 algorithms for surrogation analysis to investigate mathematical periodicity of toddlers’ strides. Results show that toddlers’ LyE values were not different between groups or with practice and strides of both groups become more periodic with practice. PMID:20237407

    The ciliopathies are a group of heterogeneous diseases with considerable variations in phenotype for allelic conditions such as Meckel–Gruber syndrome (MKS) and Joubert syndrome (JBTS) even at the inter-individual level within families. In humans, mutations in TMEM67 (also known as MKS3) cause both MKS and JBTS, with TMEM67 encoding the orphan receptor meckelin (TMEM67) that localizes to the ciliary transition zone. We now describe the Tmem67tm1(Dgen/H) knockout mouse model that recapitulates the brain phenotypic variability of these human ciliopathies, with categorization of Tmem67 mutant animals into two phenotypic groups. An MKS-like incipient congenic group (F6 to F10) manifested very variable neurological features (including exencephaly, and frontal/occipital encephalocele) that were associated with the loss of primary cilia, diminished Shh signalling and dorsalization of the caudal neural tube. The ‘MKS-like’ group also had high de-regulated canonical Wnt/β-catenin signalling associated with hyper-activated Dishevelled-1 (Dvl-1) localized to the basal body. Conversely, a second fully congenic group (F > 10) had less variable features pathognomonic for JBTS (including cerebellar hypoplasia), and retention of abnormal bulbous cilia associated with mild neural tube ventralization. The ‘JBTS-like’ group had de-regulated low levels of canonical Wnt signalling associated with the loss of Dvl-1 localization to the basal body. Our results suggest that modifier alleles partially determine the variation between MKS and JBTS, implicating the interaction between Dvl-1 and meckelin, or other components of the ciliary transition zone. The Tmem67tm1(Dgen/H) line is unique in modelling the variable expressivity of phenotypes in these two ciliopathies. PMID:23283079

    Full Text Available The objective of this study was to assess variability in symptoms and physical capabilities in chronic fatigue syndrome (CFS participants both before and after a graded exercise intervention. Sixty-one CFS subjects participated in a 12-week randomized controlled trial of either graded exercise (n =32 or relaxation/stretching therapy (n = 29. Specific physiological, psychological and cognitive variables were assessed once weekly over a four-week period both prior to and after the intervention period. All scores were assessed for reliability using an intraclass correlation coefficient (ICC. Apart from mental and physical fatigue, baseline ICC scores for all variables assessed were moderately to highly reliable, indicating minimal variability. Baseline scores for mental and physical fatigue were of questionable reliability, indicating a fluctuating nature to these symptoms (R1 = 0.64 and 0.60, respectively. Variability in scores for mental fatigue was reduced after graded exercise to an acceptable classification (R1 = 0.76. Results from this study support a variable nature to the symptoms of mental and physical fatigue only. Consequently, in order to more accurately report the nature of mental and physical fatigue in CFS, future studies should consider using repeated-measures analysis when assessing these symptoms. Graded exercise resulted in the reclassification of scores for mental fatigue from questionable to acceptable reliability

    Sensenbrenner syndrome and unclassified short rib-polydactyly conditions are ciliopathies with overlapping phenotypes and genetic heterogeneity. Mutations in WDR35 were identified recently in a sub-group of patients with Sensenbrenner syndrome and in a single family that presented with an unclassified form of short-rib polydactyly (SRP) syndrome. We report on siblings with an unusual combination of phenotypes: narrow thorax, short stature, minor anomalies, developmental delay, and severe hepatic fibrosis leading to liver failure and early death in two of the children. Both parents were unaffected suggesting autosomal recessive inheritance. The family and their affected children were followed over a decade. Exome sequencing was performed in one affected individual. It showed a homozygous missense mutation in a highly conserved position of the WDR35 gene. This family represents a WDR35-ciliopathy with a complex clinical presentation that includes significant overlap of the phenotypes described in Sensenbrenner syndrome and the unclassified SRPs. The accurate molecular diagnosis of this family exemplifies the power of exome sequencing in the diagnosis of Mendelian disorders and enabled us to broaden and refine our understanding of Sensenbrenner syndrome and SRP. Detailed genotype-phenotype information is provided as well as discussion of previously reported cases.

    Despite the advances in understanding visuo-spatial processing in developmental disorders such as ASD and fragile X syndrome (FXS), less is known about the profile of those with a comorbid diagnosis, or the role of within-disorder disparities between individuals across the ASD spectrum. Using a developmental trajectory approach, we tested 5 groups of children: Typically developing, FXS, FXS+ASD, ASD individuals who had low-moderate symptoms (HFA) and ASD individuals who had severe symptoms (LFA). Symptoms of ASD were assessed using the Childhood Autism Rating Scale: CARS and hierarchical visuo-spatial processing was assessed using the Navon task. Crucially, results differed between HFA and LFA participants. Furthermore, the pattern of results differed between those who had a diagnosis of FXS only and FXS+ASD. Poorer performance within the FXS groups and the group who are low functioning on the ASD spectrum indicated a delayed developmental rate compared to typical controls. This study showed that diagnosis and severity of symptoms are indicative of differences in visuo-spatial processing styles. It is important that heterogeneity within FXS and ASD populations are considered in subsequent studies and look beyond diagnostic group differences. Copyright © 2015 Elsevier Ltd.

    We report the case of a young boy with fine hair, mild nail dysplasia, blocked nasolacrimal ducts, absence of central incisors, bilateral oligodactyly of feet and anal stenosis. His father showed the same spectrum of anomalies with mild expression. He had mild nail dysplasia, blocked nasolacrimal ducts, inferior dental cysts with consequent premature tooth loss, frequent dental decays consequent to enamel abnormality and cutaneous syndactyly of the second and third right toe. The acro-dermato-ungual-lacrimal-tooth syndrome was suspected and molecular analysis of the P63 gene was performed, but no mutation was found. Although P63 gene analysis was negative, we think that both cases show clinical overlap with the acro-dermato-ungual-lacrimal-tooth syndrome and confirm the wide expression of this condition, even in the same family.

    Patau syndrome (trisomy 13) is very rare in live-born babies. Individuals with this chromosomal syndrome have a short lifespan and are rarely seen beyond infancy. This study is aimed at the clinical spectrum, natural history, and survival of patients with trisomy 13. We reviewed the detailed data of 13 Patau syndrome live-born babies. Among them two individuals were delivered from continuation of pregnancy even after prenatal diagnosis. The remaining 11 patients were born to younger mothers who did not undergo amniocentesis because no major anomalies except for cleft lip/palate were found on prenatal sonograms. The common features of Patau syndrome including the clinical triad (microphthalmia, cleft lip/palate, and polydactyly) and non-cyanotic heart defects were always found in our series. However, certain serious central defects (holoprosencephaly, omphalocele, and single umbilical artery), which are easily recognized from prenatal sonogram, occurred less frequently than those stated in the literature. The median survival time was 95 days and was longer than that previously reported. There were two infants with trisomic mosaicism with different outcomes in both clinical spectrum and survival. Otherwise, we also found the increased recurrence risks of aneuploidy in two individuals, and the longest survivor (84 months) of non-mosaic trisomy 13 in Taiwan. We thus suggest that long-term survival in our series is strongly correlated with different expressivity after prenatal selection, in addition to cytogenetic mosaicism. Less associated anomalies such as polyhydramnios, oligohydramnios, intrauterine growth retardation, single umbilical artery, eye defects, holoprosencephaly, omphalocele, and polycystic kidney may contribute to their clinical courses.

    Full Text Available BACKGROUND Polycystic Ovary Syndrome (PCOS is one of the most common endocrinopathy in premenopausal women. AIM The aim of the study was to evaluate the effectiveness of the Poincare plot analysis of Heart Rate Variability (HRV in PCOS. METHODS AND MATERIALS 24 PCOS diagnosed by Rotterdam 2003 Diagnostic Criteria and were of lean and ideal weight as per WHO criteria and 24 BMI matched, age matched normally menstruating women served as study participants. People of the study group underwent 5 min of ECG, which was evaluated for HRV. HRV analysed were Geometrical parameters (HRV, TRI, INDEX, TINN, Total Power (TP and Poincare plot parameters (SD1, SD2, SD1/SD2, S. RESULTS The Poincare scatter grams were narrower in patients and wider in control groups showing parasympathetic withdrawal and sympathetic dominance, but were not statistically significant. Area (S, TP and HRV TRI INDEX, TINN showed overall decrease in autonomic activity denoting altered sympathovagal balance favouring sympathetic dominance. There was a significant correlation of TP, SD1, SD2, S, TINN and HRV TRI INDEX with increased Rate Pressure Product (RPP as well as with one another, but not with BMI. The regression analysis did not lay forward the independent associations of these variables. DISCUSSION AND CONCLUSION This study indicates the total variability is decreased even in young, lean and ideal weight PCOS patients. Larger studies are needed to evaluating the short- and long-term variability.

    Joint hypermobility syndrome (JHS) and Ehlers-Danlos syndrome, hypermobility type (EDS-HT) are two markedly overlapping heritable connective tissue disorders. The cumulative frequency of JHS and EDS-HT seems high, but their recognition remains an exclusion diagnosis based on different sets of diagnostic criteria. Although proposed by a panel of experts, clinical identity between JHS and EDS-HT is still a matter of debate due to unknown molecular basis. We present 23 families with three or more individuals with a diagnosis of JHS and/or EDS-HT. Rough data from the 82 individuals were used to assess the frequency of major and minor criteria, as well as selected additional features. A series of statistical tools were applied to assess intrafamilial and interfamilial variability, emphasizing intergenerational, and intersex differences. This study demonstrates marked heterogeneity within and between families in terms of agreement of available diagnostic criteria. In 21 pedigrees affected individuals belong to two or three phenotypic sub-categories among JHS, EDS-HT, and JHS + EDS-HT overlap. Intergenerational analysis depicts a progressive shifting, also within the same pedigree, from EDS-HT in childhood, to JHS + EDS-HT in early adulthood and JHS later in life. Female-male ratio is 2.1:1, which results lower than previously observed in unselected patients' cohorts. In these pedigrees, JHS, EDS-HT, and JHS + EDS-HT segregate as a single dominant trait with complete penetrance, variable expressivity, and a markedly evolving phenotype. This study represents a formal demonstration that EDS-HT and JHS contitute the same clinical entity, and likely share the same genetic background, at least, in familial cases.

    Saethre-Chotzen syndrome is an autosomal dominant disease characterized by craniosynostosis, ptosis, and limb and external ear abnormalities. Variable expressivity is a well-known phenomenon in this disorder. A large Indian family has been recently identified as carrying a nonsense TWIST mutation (Q28 X) in 17 members, of whom 16 were examined in detail. Only 4 (25%) of the patients showed patent craniostenosis, namely, oxycephaly. The penetrance of craniosynostosis in this family is lower than previously reported in the literature. Fifteen patients (93%) had moderate to severe ptosis. Minor limb and external ear abnormalities were present in most patients. Eyelid features were the hallmark of the disease for 12 members of the family, suggesting that mutations in TWIST may lead to a phenotype with mainly palpebral features and no craniostenosis. The clinical analysis of this large family clearly illustrates the significant variable expressivity, probably related to haploinsufficiency because of the TWIST mutation. This phenotypic variability remains unclear but could be the result of modifier genes and/or genetic background effect, as noticed previously in the transgenic twist-null heterozygous mice.

  16. Atmospheric moisture variability and transmission of hemorrhagic fever with renal syndrome in Changsha City, Mainland China, 1991-2010.

    Full Text Available BACKGROUND: The transmission of hemorrhagic fever with renal syndrome (HFRS is influenced by environmental determinants. This study aimed to explore the association between atmospheric moisture variability and the transmission of hemorrhagic fever with renal syndrome (HFRS for the period of 1991-2010 in Changsha, China. METHODS AND FINDINGS: Wavelet analyses were performed by using monthly reported time series data of HFRS cases to detect and quantify the periodicity of HFRS. A generalized linear model with a Poisson distribution and a log link model were used to quantify the relationship between climate and HFRS cases, highlighting the importance of moisture conditions. There was a continuous annual oscillation mode and multi-annual cycle around 3-4 years from 1994 to 1999. There was a significant association of HFRS incidence with moisture conditions and the Multivariate El Niño-Southern Oscillation Index (MEI. Particularly, atmospheric moisture has a significant effect on the propagation of HFRS; annual incidence of HFRS was positively correlated with annual precipitation and annual mean absolute humidity. CONCLUSIONS: The final model had good accuracy in forecasting the occurrence of HFRS and moisture condition can be used in disease surveillance and risk management to provide early warning of potential epidemics of this disease.

    Parasympathetic function is important in the induction and maintenance of sleep. We examined whether nocturnal vagal modulation of heart rate is related to the poor sleep quality commonly reported in chronic fatigue syndrome (CFS). Heart rate (HR, as R-R intervals) was continuously monitored during sleep in 20 patients with CFS and 20 matched control subjects. Questionnaires assessed demographic information, symptoms, functional impairment, and subjective sleep quality. CFS was associated with more sleep problems in general and poorer subjective sleep quality on the study night (all p sleep were significantly lower in patients with CFS (all p heart rate variability (HRV) parameters were the best predictors of subjective sleep measures. This study identified significant reductions in vagal modulation of heart rate during sleep in CFS. Low HRV strongly predicted sleep quality-suggesting a pervasive state of nocturnal sympathetic hypervigilance in CFS.

    Full Text Available Abstract Background The kyphoscoliotic type of Ehlers-Danlos syndrome (EDS VIA (OMIM 225400 is a rare inheritable connective tissue disorder characterized by a deficiency of collagen lysyl hydroxylase 1 (LH1; EC 1.14.11.4 due to mutations in PLOD1. Biochemically this results in underhydroxylation of collagen lysyl residues and, hence, an abnormal pattern of lysyl pyridinoline (LP and hydroxylysyl pyridinoline (HP crosslinks excreted in the urine. Clinically the disorder is characterized by hypotonia and kyphoscoliosis at birth, joint hypermobility, and skin hyperelasticity and fragility. Severe hypotonia usually leads to delay in gross motor development, whereas cognitive development is reported to be normal. Methods We describe the clinical, biochemical and molecular characterisation, as well as electron microscopy findings of skin, in 15 patients newly diagnosed with this rare type of Ehlers-Danlos syndrome. Results Age at diagnosis ranged from 5 months to 27 years, with only 1/3 of the patients been diagnosed correctly in the first year of life. A similar disease frequency was found in females and males, however a broad disease severity spectrum (intra- and interfamilial, independent of molecular background or biochemical phenotype, was observed. Kyphoscoliosis, one of the main clinical features was not present at birth in 4 patients. Importantly we also noted the occurrence of vascular rupture antenatally and postnatally, as well as developmental delay in 5 patients. Conclusion In view of these findings we propose that EDS VIA is a highly variable clinical entity, presenting with a broad clinical spectrum, which may also be associated with cognitive delay and an increased risk for vascular events. Genotype/phenotype association studies and additional molecular investigations in more extended EDS VIA populations will be necessary to further elucidate the cause of the variability of the disease severity.

    Rett syndrome is caused by mutations in the X-linked MECP2 gene, which encodes a chromosomal protein that binds to methylated DNA. Mouse models mirror the human disorder and therefore allow investigation of phenotypes at a molecular level. We describe an Mecp2 allelic series representing the three most common missense Rett syndrome (RTT) mutations, including first reports of Mecp2[R133C] and Mecp2[T158M] knock-in mice, in addition to Mecp2[R306C] mutant mice. Together these three alleles comprise ∼25% of all RTT mutations in humans, but they vary significantly in average severity. This spectrum is mimicked in the mouse models; R133C being least severe, T158M most severe and R306C of intermediate severity. Both R133C and T158M mutations cause compound phenotypes at the molecular level, combining compromised DNA binding with reduced stability, the destabilizing effect of T158M being more severe. Our findings contradict the hypothesis that the R133C mutation exclusively abolishes binding to hydroxymethylated DNA, as interactions with DNA containing methyl-CG, methyl-CA and hydroxymethyl-CA are all reduced in vivo. We find that MeCP2[T158M] is significantly less stable than MeCP2[R133C], which may account for the divergent clinical impact of the mutations. Overall, this allelic series recapitulates human RTT severity, reveals compound molecular aetiologies and provides a valuable resource in the search for personalized therapeutic interventions.

    Accumulating evidence on blood pressure (BP) reduction with various angiotensin II receptor blockers (ARBs) show that the magnitudes and durations of BP control differ across ARBs. However, the mechanism of ARBs is unknown. This work was undertaken to compare telmisartan and valsartan in duration of BP control, BP variability, and effects on the autonomic nervous system. Using radiotelemetry combined with spectral analysis with a fast Fourier transformation algorithm, we compared the effects of various doses of telmisartan and valsartan on BP and its variability during dark (active phase) and light (inactive phase) periods over 5 weeks in SHR/NDmcr-cp(+/+)(SHRcp) rats, a model of metabolic syndrome. We also compared the effects of these ARBs on autonomic nervous system, central oxidative stress, and inflammation in SHRcp rats. Telmisartan exerted a longer-lasting BP-lowering effect and greater attenuation of BP variability in SHRcp than valsartan. Telmisartan decreased low frequency power of systolic BP and increased spontaneous baroreflex gain in SHRcp during both the dark and light periods more than valsartan. Telmisartan reduced 24-hour urinary norepinephrine excretion more than valsartan. Furthermore, telmisartan attenuated oxidative stress and the numbers of gp91(phox)-positive cells and activated microglia and astrocytes in the rostral ventrolateral medulla of SHRcp rats more than valsartan. The superiority of telmisartan over valsartan in sustained BP control and reduction of BP variability was attributed to more suppression of sympathetic activity and more improvement of baroreceptor reflex. The greater suppression of sympathetic activity by telmisartan appeared to be partially mediated by a stronger amelioration of central oxidative stress. © American Journal of Hypertension, Ltd 2014.

    The aim of this study was to compare polysomnographic variables of obese adolescents with polycystic ovarian syndrome (PCOS) to those of healthy controls and to analyse whether polysomnographic variables correlate to parameters of body weight/body composition, to serum androgens and to parameters of glucose metabolism. Thirty-one obese adolescents with PCOS (15.0 years ± 1.0, body mass index 32.7 kg per m(2) ± 6.2) and 19 healthy obese adolescents without PCOS (15.2 years ± 1.1, body mass index 32.4 kg per m(2) ± 4.0) underwent polysomnography to compare apnoea index, hypopnoea index, apnoea-hypopnoea index, the absolute number of obstructive apnoeas, percentage sleep Stages 1, 2, 3 and 4 of non-rapid eye movement (NREM) sleep, percentage of REM sleep, TIB, total sleep time (TST), sleep-onset latency, total wake time (TWT), wakefulness after sleep onset (WASO) and sleep efficiency. Furthermore, we correlated polysomnographic variables to parameters of body weight/body composition, to serum androgens and to parameters of glucose metabolism. We found no differences between the two groups concerning the respiratory indices, percentage sleep Stages 2, 3 and 4 of NREM sleep, TIB and sleep-onset latency. The girls with PCOS differed significantly from the controls regarding TST, WASO, TWT, sleep efficiency, percentage Stage 1 of NREM sleep and percentage of REM sleep. We found a weak significant correlation between insulin resistance and apnoea index and between insulin resistance and apnoea-hypopnoea index. Concerning the respiratory variables, adolescents with PCOS do not seem to differ from healthy controls; however, there seem to be differences concerning sleep architecture.

    We used segregation analysis to investigate the genetic basis of variation in dystopia canthorum, one of the key diagnostic features of Waardenburg syndrome type 1 (WS1). We sought to determine whether the W-index, a quantitative measure of this craniofacial feature, is influenced primarily either by allelic variation in the PAX3 disease gene or other major loci, by polygenic background effects, or by all of these potential sources of genetic variation. We studied both WS1-affected individuals and their WS1-unaffected relatives. After adjustment of the W-index for WS1 disease status, segregation analyses by the regression approach indicated major-locus control of this variation, although residual parent-offspring and sib-sib correlations are consistent with additional (possibly polygenic) effects. Separate analyses of WS1-affected and WS1-unaffected individuals suggest that epistatic interactions between disease alleles at the PAX3 WS1 locus and a second major locus influence variation in dystopia canthorum. Our approach should be applicable for assessing the genetic architecture of variation associated with other genetic diseases. 23 refs., 1 fig., 6 tabs.

Our approach should be applicable for assessing the genetic architecture of variation associated with other genetic diseases.

    Full Text Available Abstract Background The aim of this paper was to determine the most common craniofacial changes in patients suffering Obstructive Sleep Apnea Syndrome (OSAS with regards to the degree of obesity. Accordingly, cephalometric data reported in the literature was searched and analyzed. Methods After a careful analysis of the literature from 1990 to 2006, 5 papers with similar procedural criteria were selected. Inclusion criteria were: recruitment of Caucasian patients with an apnea-hypopnea index (AHI >10 as grouped in non-obese (Body Mass Index – [BMI] vs. obese (BMI ≥ 30. Results A low position of the hyoid bone was present in both groups. In non-obese patients, an increased value of the ANB angle and a reduced dimension of the cranial base (S-N were found to be the most common finding, whereas major skeletal divergence (ANS-PNS ^Go-Me was evident among obese patients. No strict association was found between OSAS and length of the soft palate. Conclusion In both non-obese and obese OSAS patients, skeletal changes were often evident; with special emphasis of intermaxillary divergence in obese patients. Unexpectedly, in obese OSAS patients, alterations of oropharyngeal soft tissue were not always present and did not prevail.

    We determined whether alterations in heart rate dynamics during sleep in patients with chronic fatigue syndrome (CFS) differed from controls and/or correlated with changes of sleepiness before and after a night in the sleep laboratory. We compared beat-to-beat RR intervals (RRI) during nocturnal sleep, sleep structure, and subjective scores on visual analog scale for sleepiness in 18 CFS patients with 19 healthy controls aged 25-55 after excluding subjects with sleep disorders. A short-term fractal scaling exponent (α1) of RRI dynamics, analyzed by the detrended fluctuation analysis (DFA) method, was assessed after stratifying patients into those who reported more or less sleepiness after the night's sleep (a.m. sleepier or a.m. less sleepy, respectively). Patients in the a.m. sleepier group showed significantly (psleep (Stages 1, 2, and 3 sleep) than healthy controls, although standard polysomnographic measures did not differ between the groups. The fractal scaling index α1 during non-REM sleep was significantly (psleep onset for healthy controls and patients in the a.m. less sleepy group, but did not differ between sleep stages for patients in the a.m. sleepier group. For patients, changes in self-reported sleepiness before and after the night correlated positively with the fractal scaling index α1 during non-REM sleep (psleep might be associated with disrupted sleep in patients with CFS.

    Multilocus variable-number tandem-repeat analysis (MLVA) was compared to multilocus sequence typing (MLST) to differentiate hemolytic uremic syndrome-associated enterohemorrhagic Escherichia coli strains. Although MLVA—like MLST—was highly discriminatory (index of diversity, 0.988 versus 0.984), a low level of concordance demonstrated the limited ability of MLVA to reflect long-term evolutionary events.

    Lesch-Nyhan disease is an inborn error of purine metabolism that results from deficiency of the activity of hypoxanthine phosphoribosyltransferase (HPRT). The heterogeneity of clinical phenotypes seen in HPRT deficiency corresponds to an inverse relationship between HPRT enzyme activity and clinical severity. With rare exception, each mutation produces a stereotypical pattern of clinical disease; onset of neurologic symptoms occurs during infancy and is thought to be nonprogressive. To document a family in which a single HPRT gene mutation has led to 3 different clinical and enzymatic phenotypes. Case report. Settings A university-based outpatient metabolic clinic and a biochemical genetics laboratory. Patients Three males (2 infants and their grandfather) from the same family with Lesch-Nyhan variant, including one of the oldest patients with Lesch-Nyhan variant at diagnosis (65 years). Clinical and biochemical observations. Sequencing of 5 family members revealed a novel mutation c.550G>T in exon 7 of the HPRT gene. The considerably variable clinical phenotype corresponded with the variable enzymatic activity in the 3 males, with the grandfather being the most severely affected. The different phenotypes encountered in the enzymatic analysis of cultured fibroblasts from a single mutation in the same family is unprecedented. The significant decrease in the grandfather's HPRT enzymatic activity compared with that of his grandchildren could be a function of the Hayflick Limit Theory of cell senescence.

    Some approaches have been published in the past using Heart Rate Variability (HRV) spectral features for the screening of Sleep Apnea-Hypopnea Syndrome (SAHS) patients. However there is a big variability among these methods regarding the selection of the source signal and the specific spectral components relevant to the analysis. In this study we investigate the use of the Heart Timing (HT) as the source signal in comparison to the classical approaches of Heart Rate (HR) and Heart Period (HP). This signal has the theoretical advantage of being optimal under the Integral Pulse Frequency Modulation (IPFM) model assumption. Only spectral bands defined as standard for the study of HRV are considered, and for each method the so-called LF/HF and VLFn features are derived. A comparative statistical analysis between the different resulting methods is performed, and subject classification is investigated by means of ROC analysis and a Naïve-Bayes classifier. The standard Apnea-ECG database is used for validation purposes. Our results show statistical differences between SAHS patients and controls for all the derived features. In the subject classification task the best performance in the testing set was obtained using the LF/HF ratio derived from the HR signal (Area under ROC curve=0.88). Only slight differences are obtained due to the effect of changing the source signal. The impact of using the HT signal in this domain is therefore limited, and has not shown relevant differences with respect to the use of the classical approaches of HR or HP.

    The aim of this literature review was to identify the biomechanical variables involved in the aetiology of iliotibial band syndrome (ITBS) in distance runners. An electronic search was conducted using the terms "iliotibial band" and "iliotibial tract". The results showed that runners with a history of ITBS appear to display decreased rear foot eversion, tibial internal rotation and hip adduction angles at heel strike while having greater maximum internal rotation angles at the knee and decreased total abduction and adduction range of motion at the hip during stance phase. They further appear to experience greater invertor moments at their feet, decreased abduction and flexion velocities at their hips and to reach maximum hip flexion angles earlier than healthy controls. Maximum normalised braking forces seem to be decreased in these athletes. The literature is inconclusive with regards to muscle strength deficits in runners with a history of ITBS. Prospective research suggested that greater internal rotation at the knee joint and increased adduction angles of the hip may play a role in the aetiology of ITBS and that the strain rate in the iliotibial bands of these runners may be increased compared to healthy controls. A clear biomechanical cause for ITBS could not be devised due to the lack of prospective research.

Background: Patients with ACS are at risk for both cardiac autonomic dysfunction and clinical depression. Both conditions can negatively impact the ability to recover from an acute physiological insult, such as unstable angina or myocardial infarction, increasing the risk for adverse cardiovascular outcomes. HRV is recognized as a reflection of autonomic function. Methods: A narrative review was undertaken to evaluate state-of-the-art clinical research, using the PubMed database, January 2013. The search terms “heart rate variability” and “depression” were used in conjunction with “acute coronary syndrome”, “unstable angina”, or “myocardial infarction” to find clinical studies published within the past 10 years related to HRV and clinical depression, in patients with an ACS episode. Studies were included if HRV measurement and depression screening were undertaken during an ACS hospitalization or within 2 months of hospital discharge. Results: Nine clinical studies met the inclusion criteria. The

    Full Text Available RP Lazaro Department of Neurology, Albany Medical College, Albany, NY, USA Objective: The aim of this study was to demonstrate the ramifications of clinical variability of complex regional pain syndrome (CRPS and how they can affect the various aspects of this condition, favorably or unfavorably, for both patients and participating medical and legal professionals.Methods: Twelve patients diagnosed with CRPS at different times in the past 25 years were followed up, and their signs and symptoms were reviewed for variability. None had preexisting or ongoing medical disorders and prior injury to the peripheral nerves or musculoskeletal tissues. None had been involved in litigation. Physical traumas that triggered CRPS were job-related, vehicular accidents, and personal injuries. The presence of vasomotor symptoms (eg, swelling, skin discoloration, and temperature changes and allodynia in the affected extremity was the basis for clinical diagnosis in all the patients. The need for imaging studies was precluded in some patients owing to the presence of vasomotor symptoms, which either fluctuated or were steady. Seven of the patients had type 1 CRPS, and five patients had type 2 CRPS. Results: Most patients encountered delay in diagnosis and treatment and legal obstacles owing to the lack of “typical” objective signs of CRPS. The patients’ symptoms fluctuated at different times of the day. Eight patients experienced spread of vasomotor symptoms and varying degree of allodynia in the opposite extremity. One patient, who developed signs and symptoms of rheumatoid arthritis, 2 months after the injury, continued to have CRPS symptoms in the injured hand. Treatment modalities administered in all the patients were essentially ineffective. All the patients, except one, were unable to return to their original line of work, and their symptoms persisted regardless of the outcome of their legal claims.Conclusion: It is likely that patients who continue to

    The clinical use of array comparative genomic hybridization in the evaluation of patients with multiple congenital anomalies and/or mental retardation has recently led to the discovery of a number of novel microdeletion and microduplication syndromes. We present four male patients with overlapping molecularly defined de novo microdeletions of 16q24.3. The clinical features observed in these patients include facial dysmorphisms comprising prominent forehead, large ears, smooth philtrum, pointed chin and wide mouth, variable cognitive impairment, autism spectrum disorder, structural anomalies of the brain, seizures and neonatal thrombocytopenia. Although deletions vary in size, the common region of overlap is only 90 kb and comprises two known genes, Ankyrin Repeat Domain 11 (ANKRD11) (MIM 611192) and Zinc Finger 778 (ZNF778), and is located approximately 10 kb distally to Cadherin 15 (CDH15) (MIM 114019). This region is not found as a copy number variation in controls. We propose that these patients represent a novel and distinctive microdeletion syndrome, characterized by autism spectrum disorder, variable cognitive impairment, facial dysmorphisms and brain abnormalities. We suggest that haploinsufficiency of ANKRD11 and/or ZNF778 contribute to this phenotype and speculate that further investigation of non-deletion patients who have features suggestive of this 16q24.3 microdeletion syndrome might uncover other mutations in one or both of these genes.

    Full Text Available We investigated manual needle and laser needle acupuncture as a complementary therapy for patients with burnout syndrome. Twenty patients with a mean age ± SD of 38.7 ± 8.4 years were assigned to two groups, each consisting of ten patients. One group was treated with manual needle acupuncture and the other with laser needle acupuncture. Heart rate, heart rate variability (HRV, and a new score called dynamic acupuncture treatment score (DATS served as evaluation parameters. The study documented significant effects on heart rate after needle acupuncture treatment and significant effects on HRV caused by both needle and laser needle acupuncture. Based on new neurovegetative acupuncture treatment evaluation scores, it can be stated that both noninvasive laser needle acupuncture and manual needle acupuncture have the potential to be a powerful approach for evidence-based complementary treatment of patients with burnout syndrome. Further transcontinental studies to verify or refute the preliminary findings are in progress.

    Most targeted gene mutations are recessive and analyses of gene function often focus on homozygous mutant phenotypes. Here we describe parts of the expression pattern of M-twist in the head of developing wild-type mice and present our analysis of the phenotype of heterozygous twist- null animals at around birth and in adults. A number of twist -null heterozygous mice present skull and limb defects and, in addition, we observed other malformations, such as defects in middle ear formation and the xyphoïd process. Our study is of interest to understand bone formation and the role of M-twist during this process, as within the same animal growth of some bones can be accelerated while for others it can be delayed. Moreover, we show here that expressivity of the mouse mutant heterozygous phenotype is dependent on the genetic background. This information might also be helpful for clinicians, since molecular defects affecting one allele of the human H-twist ( TWIST ) gene were identified in patients affected with Saethre-Chotzen syndrome (SCS). Expressivity of this syndrome is variable, although most patients present craniofacial and limb malformations resembling those seen in mutant mice. Thus the mutant mouse twist -null strain might be a useful animal model for SCS. The twist -null mutant mouse model, combined with other mutant mouse strains, might also help in an understanding of the etiology of morphological abnormalities that appear in human patients affected by other syndromes.

  4. A new mouse model for marfan syndrome presents phenotypic variability associated with the genetic background and overall levels of Fbn1 expression.

    Bruno L Lima

    Full Text Available Marfan syndrome is an autosomal dominant disease of connective tissue caused by mutations in the fibrillin-1 encoding gene FBN1. Patients present cardiovascular, ocular and skeletal manifestations, and although being fully penetrant, MFS is characterized by a wide clinical variability both within and between families. Here we describe a new mouse model of MFS that recapitulates the clinical heterogeneity of the syndrome in humans. Heterozygotes for the mutant Fbn1 allele mgΔloxPneo, carrying the same internal deletion of exons 19-24 as the mgΔ mouse model, present defective microfibrillar deposition, emphysema, deterioration of aortic wall and kyphosis. However, the onset of a clinical phenotypes is earlier in the 129/Sv than in C57BL/6 background, indicating the existence of genetic modifiers of MFS between these two mouse strains. In addition, we characterized a wide clinical variability within the 129/Sv congenic heterozygotes, suggesting involvement of epigenetic factors in disease severity. Finally, we show a strong negative correlation between overall levels of Fbn1 expression and the severity of the phenotypes, corroborating the suggested protective role of normal fibrillin-1 in MFS pathogenesis, and supporting the development of therapies based on increasing Fbn1 expression.

    DNA at the FMR-1 locus was analyzed by Southern blot using probe StB12.3 in an unusual fragile X family with six brothers, three of whom are affected with fragile X to varying degrees, two of whom are nonpenetrant carriers, and one of whom is unaffected. Fragile X chromosome studies, detailed physical examinations, and psychological testing were completed on all six. Two of the affected brothers and the two nonpenetrant brothers were found to be methylation mosaics. The three affected males spanned the phenotypic and cognitive spectrum of the fragile X syndrome. A correlation was seen between the degree of methylation and the phenotypic expression identified in the three affected males. The two males initially classified as nonpenetrant were found to have mild phenotypic expression which consisted of minor cognitive deficits and a partial physical phenotype. These two, who were negative on fragile X chromosome studies, were found on DNA analysis to have large broad smears, with approximately 97% of the DNA unmethylated. The results described here indicate that some [open quotes]nonpenetrant[close quotes] carrier males may have varying amounts of methylation of the FMR-1 region, which can result in mild expression of the fragile X syndrome. The apparently mild phenotypic and cognitive expression of the fragile X syndrome in the two males, initially classified as nonpenetrant, who are mosaic for hypermethylation of an expansion of the CGG repeat in the premutation range, indicates that expression of the syndrome is not confined to males with large, hypermethylated expansions (full mutation) but has instead a gradient effect with a threshold for the full expression of the phenotype. 41 refs., 2 tabs.

    Full Text Available BACKGROUND: The transmission of hemorrhagic fever with renal syndrome (HFRS is influenced by population dynamics of its main host, rodents. It is therefore important to better understand rodents' characteristic in epidemic areas. METHODOLOGY/PRINCIPAL FINDINGS: We examined the potential impact of food available and climatic variability on HFRS rodent host and developed forecasting models. Monthly rodent density of HFRS host and climate data in Changsha from January 2004 to December 2011 were obtained. Monthly normalized difference vegetation index (NDVI and temperature vegetation dryness index (TVDI for rice paddies were extracted from MODIS data. Cross-correlation analysis were carried out to explore correlation between climatic variables and food available with monthly rodent data. We used auto-regressive integrated moving average model with explanatory variables to examine the independent contribution of climatic variables and food supply to rodent density. The results indicated that relative rodent density of HFRS host was significantly correlated with monthly mean temperatures, monthly accumulative precipitation, TVDI and NDVI with lags of 1-6 months. CONCLUSIONS/SIGNIFICANCE: Food available plays a significant role in population fluctuations of HFRS host in Changsha. The model developed in this study has implications for HFRS control and prevention.

The results indicated that relative rodent density of HFRS host was significantly correlated with monthly mean temperatures, monthly accumulative precipitation, TVDI and NDVI with lags of 1-6 months. Food available plays a significant role in population fluctuations of HFRS host in Changsha. The model developed in this study has implications for HFRS control and prevention.

    In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in

    The genetic causes of intellectual disability (ID) are heterogeneous and include both chromosomal and monogenic etiologies. The X-chromosome is known to contain many ID-related genes and males show a marked predominance for intellectual disability. Here we report two females with syndromic intellectual disability. The first individual was relatively mild in her presentation with mild-moderate intellectual disability, hydronephrosis and altered pigmentation along the lines of Blaschko without additional congenital anomalies. A second female presented shortly after birth with dysmorphic facial features, post-axial polydactyly and, on follow-up assessment, demonstrated moderate intellectual disability. Chromosomal studies for Individual 1 identified an X-chromosome deletion due to a de novo pericentric inversion; the inversion breakpoint was associated with deletion of the 5'UTR of the USP9X, a gene which has been implicated in a syndromic intellectual disability affecting females. The second individual had a de novo frameshift mutation detected by whole-exome sequencing that was predicted to be deleterious, NM_001039590.2 (USP9X): c.4104_4105del (p.(Arg1368Serfs*2)). Haploinsufficiency of USP9X in females has been associated with ID and congenital malformations that include heart defects, scoliosis, dental abnormalities, anal atresia, polydactyly, Dandy Walker malformation and hypoplastic corpus callosum. The extent of the congenital malformations observed in Individual 1 was less striking than Individual 2 and other individuals previously reported in the literature, and suggests that USP9X mutations in females can have a wider spectrum of presentation than previously appreciated.

    To review the clinical presentation, evaluation, and management of normal-weight (NW), overweight (OW), and obese (OB) adolescent and young adult women with polycystic ovary syndrome (PCOS) during a 2-year follow-up. Retrospective chart review. One hundred seventy-three adolescent and young adult women, aged 12-22 years, diagnosed with PCOS. Demographic, health data, and laboratory measures were abstracted from 3 clinic visits: baseline and 1- and 2-year follow-up. Subjects were classified as NW, OW, or OB. Longitudinal data were analyzed using repeated-measures analysis of variance. Body mass index, self-reported concerns, and lifestyle changes. Most patients (73%) were OW or OB. Family history of type 2 diabetes was greater in OW (38%) and OB (53%) patients compared with NW (22%) patients (P = .002). Acanthosis nigricans was identified in OW (62%) and OB (21%) patients but not in NW patients (0%; P change in body mass index percentile occurred. Evidence-based interventions and recommendations for screening tests are needed to address CVD risk in adolescents and young adults with PCOS.

    To examine interactions between demographic, pain, urinary, psychological and environmental predictors of quality of life (QOL) in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). In all, 253 men previously enrolled in the National Institutes of Health Chronic Prostatitis Cohort study in North American tertiary-care clinical centres (six in the USA and one in Canada) self-reported with validated instruments, including the QOL subscales of the Short Form-12 (physical, SF12-PCS; and mental, SF12-MCS), demographics, urinary symptoms, depression, current pain, pain coping, 'catastrophizing' (catastrophic thinking about pain), pain control, social support and solicitous responses from a partner. Data were collected through a one-time survey. Covariates determined to be significant were entered into a multivariable regression model predicting SF12-PCS and SF12-MCS. Adjusting for covariates, regression models showed that poorer SF12-PCS scores were predicted by worse urinary function (P patients with CP/CPPS adjust. These data can be used to develop specific cognitive-behavioural programmes for men with CP/CPPS who are refractory to standard medical therapy.

    The aim of the present study was to evaluate the hemodynamic and respiratory variations in patients with acute respiratory distress syndrome (ARDS) under two conditions: volume controlled ventilation (VCV) and pressure controlled inverse ratio ventilation (PCIRV). Seventeen patients with ARDS and the following criteria were included: lung injury score > 2.5 and peak inspiratory pressure > or = 40 cm H2O under VCV, constant flow and I/E ratio of 1/2. Measurements were obtained in VCV and after one hour in PCIRV with I/E ratio 2/1 using a similar PEEP value than VCV. PCIRV was accompanied by a significant lower tidal volume (736.10 +/- 119.20 vs 540.35 +/- 84.66 p SDRA, which is shown with the improvement in the static compliance and the airway pressures in PCIRV. PCIRV mode at the same PEEPt level as VCV, with normal I/E ratio does not improve the oxygenation, despite the higher level of the mean airway pressure.

    2013-12-01

    A cohort of patients with overgrowth syndromes has been identified with congenital lipomatous overgrowth, dysregulated fat deposits, and mixed vascular malformations. The acronym CLOVES was given on a heuristic basis to stand for congenital lipomatous overgrowth (CLO), vascular malformation (V), epidermal nevi (E), and scoliosis and spinal deformities (S). These patients have upper limb anomalies with variable phenotypes. Although hand anomalies alone cannot make the diagnosis, the foot, truncal, cutaneous and spinal anomalies are particularly diagnostic. CLOVES syndrome has emerged as a distinct clinical entity diagnosed by clinical and radiographic examinations. The overgrowth pattern is now easily distinguished from other overgrowth syndromes.

    Autonomic dysregulation and heterogeneous symptoms characterize postural orthostatic tachycardia syndrome (POTS). This study evaluated the effect of high-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM(®)), a noninvasive, allostatic neurotechnology for relaxation and auto-calibration of neural oscillations, on heart rate variability, brain asymmetry, and autonomic symptoms, in adolescents with POTS. Seven subjects with POTS (three males, ages 15-18) underwent a median of 14 (10-16) HIRREM sessions over 13 (8-17) days. Autonomic function was assessed from 10-min continuous heart rate and blood pressure recordings, pre- and post-HIRREM. One-minute epochs of temporal high-frequency (23-36 Hz) brain electrical activity data (T3 and T4, eyes closed) were analyzed from baseline HIRREM assessment and subsequent sessions. Subjects rated autonomic symptoms before and after HIRREM. Four of seven were on fludrocortisone, which was stopped before or during their sessions. Heart rate variability in the time domain (standard deviation of the beat-to-beat interval) increased post-HIRREM (mean increase 51%, range 10-143, p = 0.03), as did baroreflex sensitivity (mean increase in high-frequency alpha 65%, range -6 to 180, p = 0.05). Baseline temporal electrical asymmetry negatively correlated with change in asymmetry from assessment to the final HIRREM session (p = 0.01). Summed high-frequency amplitudes at left and right temporal lobes decreased a median of 3.8 μV (p = 0.02). There was a trend for improvements in self-reported symptoms related to the autonomic nervous system. Use of HIRREM was associated with reduced sympathetic bias in autonomic cardiovascular regulation, greater symmetry and reduced amplitudes in temporal lobe high-frequency electrical activity, and a trend for reduced autonomic symptoms. Data suggest the potential for allostatic neurotechnology to facilitate increased flexibility in autonomic cardiovascular regulation, possibly

    Full Text Available Abstract Background Expression of inflammatory cytokines in cerebrospinal fluid (CSF has led to the hypothesis of intrathecal chronic inflammation to explain the denervation observed in post-polio syndrome (PPS. It has been shown that therapy with intravenous immunoglobulin (IVIG improves physical performance and dampens down the inflammatory process at 6 months in PPS patients. We here examined the effects of IVIG on cytokine expression and clinical outcome one year after IVIG treatment. Methods From a previous study with 135 PPS patients included, 41 patients were further evaluated before un-blinding for one year (21 placebo and 20 treated with IVIG, Xepol® 50 mg/ml, and were assessed for clinical variables by performing the Short Form-36 survey (SF-36 questionnaire assessment, the 6 minute walk distance test (6MWT and registering pain level by Visual Analogue Scale (VAS after IVIG treatment. A separate cohort of 37 PPS patients went through lumbar puncture (LP at baseline and 20 patients, treated with IVIG, repeated the LP one year later. Thirty patients affected with other neurological diseases (OND were used as control group. Inflammatory cytokines TNF, TGFβ, IFNγ, IL-23, IL-13 and IL-10 were measured in blood cells and CSF cells with RT-PCR. Results Scores of the physical components of SF-36 were significantly higher at the one year follow up time-point in the IVIG-treated patients when compared to baseline as well as to the control subjects. Pain VAS score and 6MWT improved significantly in the IVIG-treated patients when compared with baseline Relative expression of TNF and IFN-γ in both PBMCs and CSF from PPS patients were increased compared to OND subjects at baseline (p  Conclusions IVIG has effects on relevant QoL variables and inflammatory cytokines up to one year in patients with PPS. This gives a basis for scheduling IVIG in upcoming trials with this therapy.

    Blastocystis spp is a common intestinal parasite of humans and animals that has been associated to the etiology of irritable bowel syndrome (IBS); however, some studies have not found this association. Furthermore, many biological features of Blastocystis are little known. The objective of present study was to assess the generation times of Blastocystis cultures, from IBS patients and from asymptomatic carriers. A total of 100 isolates were obtained from 50 IBS patients and from 50 asymptomatic carriers. Up to 50 mg of feces from each participant were cultured in Barret's and in Pavlova's media during 48 h. Initial and final parasitological load were measured by microscopy and by quantitative PCR. Amplicons were purified, sequenced and submitted to GenBank; sequences were analysed for genetic diversity and a Bayesian inference allowed identifying genetic subtypes (ST). Generation times for Blastocystis isolates in both media, based on microscopic measures and molecular assays, were calculated. The clinical symptoms of IBS patients and distribution of Blastocystis ST 1, 2 and 3 in both groups was comparable to previous reports. Interestingly, the group of cases showed scarce mean nucleotide diversity (π) as compared to the control group (0.011±0.016 and 0.118±0.177, respectively), whilst high gene flow and small genetic differentiation indexes between different ST were found. Besides, Tajima's D test showed negative values for ST1-ST3. No statistical differences regarding parasitological load between cases and controls in both media, as searched by microscopy and by qPCR, were detected except that parasites grew faster in Barret's than in Pavlova's medium. Interestingly, slow growth of isolates recovered from cases in comparison to those of controls was observed (pBlastocystis might be easily affected by intestinal environmental changes due to IBS probably because virulent strains with slow growth may be selected, reducing their genetic variability.

    Plants do not produce antibodies. However, plants can correctly assemble functional antibody molecules encoded by mammalian antibody genes. Many plant diseases are caused by pathogen toxins. One such disease is the soybean sudden death syndrome (SDS). SDS is a serious disease caused by the fungal pathogen Fusarium virguliforme. The pathogen, however, has never been isolated from diseased foliar tissues. Thus, one or more toxins produced by the pathogen have been considered to cause foliar SDS. One of these possible toxins, FvTox1, was recently identified. We investigated whether expression of anti-FvTox1 single-chain variable-fragment (scFv) antibody in transgenic soybean can confer resistance to foliar SDS. We have created two scFv antibody genes, Anti-FvTox1-1 and Anti-FvTox1-2, encoding anti-FvTox1 scFv antibodies from RNAs of a hybridoma cell line that expresses mouse monoclonal anti-FvTox1 7E8 antibody. Both anti-FvTox1 scFv antibodies interacted with an antigenic site of FvTox1 that binds to mouse monoclonal anti-FvTox1 7E8 antibody. Binding of FvTox1 by the anti-FvTox1 scFv antibodies, expressed in either Escherichia coli or transgenic soybean roots, was initially verified on nitrocellulose membranes. Expression of anti-FvTox1-1 in stable transgenic soybean plants resulted in enhanced foliar SDS resistance compared with that in nontransgenic control plants. Our results suggest that i) FvTox1 is an important pathogenicity factor for foliar SDS development and ii) expression of scFv antibodies against pathogen toxins could be a suitable biotechnology approach for protecting crop plants from toxin-induced diseases.

    Full Text Available Abstract CHARGE syndrome was initially defined as a non-random association of anomalies (Coloboma, Heart defect, Atresia choanae, Retarded growth and development, Genital hypoplasia, Ear anomalies/deafness. In 1998, an expert group defined the major (the classical 4C's: Choanal atresia, Coloboma, Characteristic ears and Cranial nerve anomalies and minor criteria of CHARGE syndrome. Individuals with all four major characteristics or three major and three minor characteristics are highly likely to have CHARGE syndrome. However, there have been individuals genetically identified with CHARGE syndrome without the classical choanal atresia and coloboma. The reported incidence of CHARGE syndrome ranges from 0.1–1.2/10,000 and depends on professional recognition. Coloboma mainly affects the retina. Major and minor congenital heart defects (the commonest cyanotic heart defect is tetralogy of Fallot occur in 75–80% of patients. Choanal atresia may be membranous or bony; bilateral or unilateral. Mental retardation is variable with intelligence quotients (IQ ranging from normal to profound retardation. Under-development of the external genitalia is a common finding in males but it is less apparent in females. Ear abnormalities include a classical finding of unusually shaped ears and hearing loss (conductive and/or nerve deafness that ranges from mild to severe deafness. Multiple cranial nerve dysfunctions are common. A behavioral phenotype for CHARGE syndrome is emerging. Mutations in the CHD7 gene (member of the chromodomain helicase DNA protein family are detected in over 75% of patients with CHARGE syndrome. Children with CHARGE syndrome require intensive medical management as well as numerous surgical interventions. They also need multidisciplinary follow up. Some of the hidden issues of CHARGE syndrome are often forgotten, one being the feeding adaptation of these children, which needs an early aggressive approach from a feeding team. As the child

    Study Design Retrospective cohort. Background Patient-classification subgroupings may be important prognostic factors explaining outcomes. Objectives To determine effects of adding classification variables (McKenzie syndrome and pain patterns, including centralization and directional preference; Symptom Checklist Back Pain Prediction Model [SCL BPPM]; and the Fear-Avoidance Beliefs Questionnaire subscales of work and physical activity) to a baseline risk-adjusted model predicting functional status (FS) outcomes. Methods Consecutive patients completed a battery of questionnaires that gathered information on 11 risk-adjustment variables. Physical therapists trained in Mechanical Diagnosis and Therapy methods classified each patient by McKenzie syndromes and pain pattern. Functional status was assessed at discharge by patient-reported outcomes. Only patients with complete data were included. Risk of selection bias was assessed. Prediction of discharge FS was assessed using linear stepwise regression models, allowing 13 variables to enter the model. Significant variables were retained in subsequent models. Model power (R(2)) and beta coefficients for model variables were estimated. Results Two thousand sixty-six patients with lumbar impairments were evaluated. Of those, 994 (48%), 10 (variables to the baseline model did not result in significant increases in R(2). McKenzie syndrome or pain pattern explained 2.8% and 3.0% of the variance, respectively. When pain pattern and SCL BPPM were added simultaneously, overall model R(2) increased to 0.44. Although none of these increases in R(2) were significant, some classification variables were stronger predictors compared with some other variables included in the baseline model.

    Full Text Available Abstract Background Patients with Opitz GBBB syndrome present with a variable array of developmental defects including craniofacial, cardiac, and genital anomalies. Mutations in the X-linked MID1 gene, which encodes a microtubule-binding protein, have been found in ~50% of Opitz GBBB syndrome patients consistent with the genetically heterogeneous nature of the disorder. A protein highly related to MID1, called MID2, has also been described that similarly associates with microtubules. Results To identify protein partners of MID1 and MID2 we undertook two separate yeast two-hybrid screens. Using this system we identified Alpha 4, a regulatory subunit of PP2-type phosphatases and a key component of the rapamycin-sensitive signaling pathway, as a strong interactor of both proteins. Analysis of domain-specific deletions has shown that the B-boxes of both MID1 and MID2 mediate the interaction with Alpha 4, the first demonstration in an RBCC protein of a specific role for the B-box region. In addition, we show that the MID1/2 coiled-coil motifs mediate both homo- and hetero-dimerisation, and that dimerisation is a prerequisite for association of the MID-Alpha 4 complex with microtubules. Conclusions Our findings not only implicate Alpha 4 in the pathogenesis of Opitz GBBB syndrome but also support our earlier hypothesis that MID2 is a modifier of the X-linked phenotype. Of further note is the observation that Alpha 4 maps to Xq13 within the region showing linkage to FG (Opitz-Kaveggia syndrome. Overlap in the clinical features of FG and Opitz GBBB syndromes warrants investigation of Alpha 4 as a candidate for causing FG syndrome.

    PFAPA syndrome is characterized by periodic fever, pharyngitis, cervical adenitis and aphthous stomatitis. The bouts of fever can last for days or even weeks. Between crises, patients remain asymptomatic for variable periods. It appears before the age of five and has limited duration (4-8 years). Its aetiopathogeny is unknown. Corticoids are the treatment of choice. Tonsillectomy has been proposed as a solution but remains controversial. We present the case of a 4-year-old girl with PFAPA syndrome who underwent tonsillectomy in January, 2008, and we review the literature.

    Aims To analyse the effects of different modalities of exercise training on heart rate variability (HRV) in individuals with metabolic syndrome (MetS). Methods and results Eighty MetS participants (aged 50-70 years) were housed and managed in an inpatient medical centre for 21 days, including weekends. Physical activity and food intake/diet were intensively monitored. Participants were randomly assigned into three training groups, differing only by intensity of exercise: moderate-endurance-moderate-resistance ( re), high-resistance-moderate-endurance ( Re), and moderate-resistance-high-endurance ( rE). HRV was recorded before and after the intervention by 24-hour Holter electrocardiogram. Although mean 24-hour heart rate decreased more in Re than re (-11.6 ± 1.6 vs. -4.8 ± 2.1%; P = 0.010), low frequency/high frequency decreased more in re than Re (-20.4 ± 5.5% vs. + 20.4 ± 9.1%; P = 0.002) and rE (-20.4 ± 5.5% vs. -0.3 ± 11.1%; P = 0.003). Very low frequency increased more in Re than re (+121.2 ± 35.7 vs. 42.9 ± 11.3%; P = 0.004). For all HRV parameters, rE ranged between re and Re values. Low frequency/high frequency changes were linked with visceral fat loss only in re (coefficient 5.9, 95% CI 1.9-10.0; P = 0.004). By day 21, HRV parameters of MetS groups (heart rate -8.6 ± 1.0%, standard deviation of R-R intervals + 34.0 ± 6.6%, total power + 63.3 ± 11.1%; P heart rate and greater increases in very low frequency. Modality-specific relationships were observed between enhanced HRV and visceral fat loss. Clinical Trial Registration URL: http://www.clinicaltrials.gov . Unique identifier: NCT00917917.

    Full Text Available This study tested the hypothesis that an eight-week exercise intervention supported by mobile health (mHealth technology would improve metabolic syndrome (MetS risk factors and heart rate variability (HRV in a population with MetS risk factors. Participants (n=12; 3 male; aged 56.9±7.0y reported to the laboratory for assessment of MetS risk factors and fitness (VO2max at baseline (V0 and after eight-weeks (V2 of intervention. Participants received an individualized exercise prescription and a mHealth technology kit for remote monitoring of blood pressure (BP, blood glucose, physical activity and body weight via smartphone. Participants underwent 24-h ambulatory monitoring of R-R intervals following V0 and V2. Low and high frequency powers of HRV were assessed from the recording and the ratio of low-to-high frequency powers and low and high frequency power in normalized units were calculated. One-way repeated measures analysis of variance showed that waist circumference (V0: 113.1±11.0cm, V2: 108.1±14.7cm; p=0.004 and diastolic BP (V0: 81±6mmHg, V2: 76±11mmHg; p=0.04 were reduced and VO2max increased (V0: 31.3ml/kg/min, V2: 34.8ml/kg/min; p=0.02 with no changes in other MetS risk factors. Low and high frequency powers in normalized units were reduced (V0: 75.5±12.0, V2: 72.0±12.1; p=0.03 and increased (V0: 24.5±12.0, V2: 28.0±12.1; p=0.03, respectively, with no other changes in HRV. Over the intervention period, changes in systolic BP were correlated negatively with the changes in R-R interval (r=-0.600; p=0.04 and positively with the changes in heart rate (r=0.611; p=0.03, with no other associations between MetS risk factors and HRV parameters. Thus, this eight-week mHealth supported exercise intervention improved MetS risk factors and HRV parameters, but only changes in systolic BP were associated with improved autonomic function.

    Full Text Available The Gorlin-Goltz syndrome (GGS (the nevoid basal cell carcinoma syndrome—NBCCS is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions.

  16. Low-Pass Filtering Approach via Empirical Mode Decomposition Improves Short-Scale Entropy-Based Complexity Estimation of QT Interval Variability in Long QT Syndrome Type 1 Patients

    Full Text Available Entropy-based complexity of cardiovascular variability at short time scales is largely dependent on the noise and/or action of neural circuits operating at high frequencies. This study proposes a technique for canceling fast variations from cardiovascular variability, thus limiting the effect of these overwhelming influences on entropy-based complexity. The low-pass filtering approach is based on the computation of the fastest intrinsic mode function via empirical mode decomposition (EMD and its subtraction from the original variability. Sample entropy was exploited to estimate complexity. The procedure was applied to heart period (HP and QT (interval from Q-wave onset to T-wave end variability derived from 24-hour Holter recordings in 14 non-mutation carriers (NMCs and 34 mutation carriers (MCs subdivided into 11 asymptomatic MCs (AMCs and 23 symptomatic MCs (SMCs. All individuals belonged to the same family developing long QT syndrome type 1 (LQT1 via KCNQ1-A341V mutation. We found that complexity indexes computed over EMD-filtered QT variability differentiated AMCs from NMCs and detected the effect of beta-blocker therapy, while complexity indexes calculated over EMD-filtered HP variability separated AMCs from SMCs. The EMD-based filtering method enhanced features of the cardiovascular control that otherwise would have remained hidden by the dominant presence of noise and/or fast physiological variations, thus improving classification in LQT1.

    The number of periodic leg movements during sleep (PLMS index) shows high night-to-night variability, requiring multiple nights for its reliable estimation. It is currently not known if this is also the case for the degree of periodicity of leg movements, quantified by the Periodicity index. To compare night-to-night variability of PLMS and Periodicity indices in patients with restless legs syndrome (RLS) or periodic limb movement disorder (PLMD). Eighteen idiopathic RLS patients and 9 PLMD patients were recruited. Subjects underwent two consecutive full night polysomnographic studies. Polysomnographic recordings were scored and leg movement activity analyzed during sleep for the computation of the PLMS and Periodicity indices. In both patient groups, the Periodicity index showed a significantly lower degree of variability than that of PLMS index, being >6.5 times lower in RLS patients and 2 times lower in PLMD patients. These data support the use of the Periodicity index in the evaluation of PLMS in RLS and PLMD and indicate that this parameter seems to be more stable than the widely used PLMS index which has higher night-to-night variability.

    Meckel-Gruber syndrome (MKS) is a lethal rare inherited autosomal recessive disease. The syndrome is characterized by multiple congenital anomalies including polycystic kidneys, occipital encephalocele and polydactyly. The presence of two out of these anomalies is sufficient for a definitive diagnosis. At least 11 genes have been reported to-date to underlie MKS. In the current study we have retrospectively analyzed all the families at the Ha'Emek Medical Center in which the diagnosis of MKS was determined. In total, 17 affected individuals are reported, originating from 12 sibships. The diagnoses were conducted or suspected by prenatal sonography, and some of the newborns were examined. Polycystic kidneys were present in 94% of cases, occipital encephalocele in 82% and polydactyly in about half of all cases. The underlying genetic cause was identified in 11 of our families, comprising mutations in 7 different genes, revealing high genetic heterogeneity. The identification of the genetic basis of MKS in our region allows focused and data-based genetic counseling and serves as an important tool for reproductive decisions, including the prevention of recurrence of pregnancies affected with this lethal syndrome. In the near future we plan to study the prevalence of the different MKS mutations found in each community in order to consider the expansion of national genetic screening in high risk populations.

    Full Text Available Burnout syndrome has a high incidence among professional healthcare and social workers. This leads to deterioration in the quality of their working life and affects their health, the organization where they work and, via their clients, society itself. Given these serious effects, many studies have investigated this construct and identified groups at increased risk of the syndrome. The present work has 2 main aims: to compare burnout levels in potential risk groups among professional healthcare workers; and to compare them using standard and Bayesian statistical analysis. The sample consisted of 108 psycho-social care workers based at 2 centers run by the Granada Council in Spain. All participants, anonymously and individually, filled in a booklet that included questions on personal information and the Spanish adaptation of the Maslach Burnout Inventory (MBI. Standard and Bayesian analysis of variance were used to identify the risk factors associated with different levels of burnout. It was found that the information provided by the Bayesian procedure complemented that provided by the standard procedure.

    Full Text Available Gorlin-Goltz syndrome also known as nevoid basal cell carcinoma syndrome (NBCCS is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by keratocystic odontogenic tumors (KCOT in the jaw, multiple basal cell carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic examination in the first decade of life, as KCOTs are usually one of the first manifestations of the NBCCS syndrome. This article reports the case of a 12-year-old girl with Gorlin-Goltz syndrome, emphasizing its clinical and radiographic manifestation. This study highlights the importance of health professionals in the early diagnosis of this syndrome and a multidisciplinary approach to provide a better diagnosis and prognosis.

    Inherited mutations of hypoxanthine guanine phosphoribosyltransferase (HPRT) give rise to Lesch-Nyhan syndrome (LNS) or variants (LNV). We report molecular insights from real-time RT-PCR for HPRT mRNA quantification into the mechanism by which a single mutation located in exon 7 of the HPRT gene: c.500G>T, p.R167M, led to different clinical phenotypes from three male LNV-affected patients in the same family manifesting parallel differences in enzymatic activities. This approach can be applied for understanding genotype-phenotype correlations for other human genetic diseases.

In overweight and obese patients stratified by BMI, the nighttime blood pressure variability increased with the increasing AHI (P<0. 05). After controlling age, BMI and blood pressure, partial

  19. Increased chromosomal breakage in Tourette syndrome predicts the possibility of variable multiple gene involvement in spectrum phenotypes: Preliminary findings and hypothesis

    Increased chromosomal breakage was found in 12 patients with DSM-IV Tourette syndrome (TS) as compared with 10 non-TS control individuals with respect to untreated, modified RPM1-, and BrdU treated lymphocyte cultures (P < 0.001 in each category). A hypothesis is proposed that a major TS gene is probably connected to genetic instability, and associated chromosomal marker sites may be indicative of the localization of secondary genes whose altered expression could be responsible for associated comorbid conditions. This concept implies that genes influencing higher brain functions may be situated at or near highly recombigenic areas allowing enhanced amplification, duplication and recombination following chromosomal strand breakage. Further studies on a larger sample size are required to confirm the findings relating to chromosomal breakage and to analyze the possible implications for a paradigmatic shift in linkage strategy for complex disorders by focusing on areas at or near unstable chromosomal marker sites. 32 refs., 1 tab.

    The detection of the first VIIP case occurred in 2005, and adequate eye outcome measures were available for 31 (67.4%) of the 46 long duration US crewmembers who had flown on the ISS since its first crewed mission in 2000. Therefore, this analysis is limited to a subgroup (22 males and 9 females). A "cardiovascular profile" for each astronaut was compiled by examining twelve individual parameters; eleven of these were preflight variables: systolic blood pressure, pulse pressure, body mass index, percentage body fat, LDL, HDL, triglycerides, use of anti-lipid medication, fasting serum glucose, and maximal oxygen uptake in ml/kg. Each of these variables was averaged across three preflight annual physical exams. Astronaut age prior to the long duration mission, and inflight salt intake was also included in the analysis. The group of cardiovascular variables for each crew member was compared with seven VIIP eye outcome variables collected during the immediate post-flight period: anterior-posterior axial length of the globe measured by ultrasound and optical biometry; optic nerve sheath diameter, optic nerve diameter, and optic nerve to sheath ratio- each measured by ultrasound and magnetic resonance imaging (MRI), intraocular pressure (IOP), change in manifest refraction, mean retinal nerve fiber layer (RNFL) on optical coherence tomography (OCT), and RNFL of the inferior and superior retinal quadrants. Since most of the VIIP eye outcome measures were added sequentially beginning in 2005, as knowledge of the syndrome improved, data were unavailable for 22.0% of the outcome measurements. To address the missing data, we employed multivariate multiple imputation techniques with predictive mean matching methods to accumulate 200 separate imputed datasets for analysis. We were able to impute data for the 22.0% of missing VIIP eye outcomes. We then applied Rubin's rules for collapsing the statistical results across our 200 multiply imputed data sets to assess the canonical

    Patients with suspected non-ST-segment elevation acute coronary syndromes (NSTEACS) constitute a heterogeneous population with variable outcomes. Risk stratification in this population of patients is difficult due to the complexity in patient risk profile. We conducted this study to characterize the value of clinical and electrocardiographic variables for risk stratification in an unselected population of consecutive patients with NSTEACS on admission. Thirty-five clinical and electrocardiographic variables at presentation in the emergency room of 18 hospitals were prospectively analyzed in 4,115 patients with NSTEACS and related with the outcomes at 90 days. We also developed a risk score using the variables found to be independent predictors of ischemic events to facilitate risk stratification. Cardiovascular mortality was 4.3% and the rate for the outcome of either cardiovascular death or nonfatal myocardial infarction was 6.9%. The only independent predictors of mortality were age, diabetes, peripheral vascular disease, postinfarction angina, Killip class > or = 2, ST-segment depression, and elevation of cardiac markers. A risk profile using the variables found to be independent predictors of events was calculated for cardiovascular mortality and for the combination of either death or nonfatal myocardial infarction. Event rates increased significantly in all subgroups of patients based on the number of independent risk factors as the risk score increased. Using these factors, 90-day mortality ranged from as low as 0.4% in patients with no risk factors to 21.1% for those with more than 4 risk factors. In conclusion, simple clinical and electrocardiographic data obtained at hospital admission allow an accurate risk stratification of patients with NSTEACS. In the PEPA registry, simple variables easy to obtain at admission appear to be a valuable tool in discerning between patients at very low and very high risk according to the cluster of factors for each patient

    2007-09-01

    Full Text Available Abstract Sotos syndrome is an overgrowth condition characterized by cardinal features including excessive growth during childhood, macrocephaly, distinctive facial gestalt and various degrees of learning difficulty, and associated with variable minor features. The exact prevalence remains unknown but hundreds of cases have been reported. The diagnosis is usually suspected after birth because of excessive height and occipitofrontal circumference (OFC, advanced bone age, neonatal complications including hypotonia and feeding difficulties, and facial gestalt. Other inconstant clinical abnormalities include scoliosis, cardiac and genitourinary anomalies, seizures and brisk deep tendon reflexes. Variable delays in cognitive and motor development are also observed. The syndrome may also be associated with an increased risk of tumors. Mutations and deletions of the NSD1 gene (located at chromosome 5q35 and coding for a histone methyltransferase implicated in transcriptional regulation are responsible for more than 75% of cases. FISH analysis, MLPA or multiplex quantitative PCR allow the detection of total/partial NSD1 deletions, and direct sequencing allows detection of NSD1 mutations. The large majority of NSD1 abnormalities occur de novo and there are very few familial cases. Although most cases are sporadic, several reports of autosomal dominant inheritance have been described. Germline mosaicism has never been reported and the recurrence risk for normal parents is very low (

    Waardenburg syndrome (WS) is a neurocristopathy characterized by pigmentation abnormalities of the skin, hair, and iris, as well as sensorineural hearing loss. Contiguous gene deletions encompassing SOX10 are rare, which limits conclusions about genotype-phenotype correlation regarding patient prognosis and management. This study adds to the existing body of knowledge by characterizing a 2.4 Mb deletion [arr[hg19] 22q12.3-q13.1 (36467502-38878207)x1] encompassing SOX10 and 53 additional RefSeq genes in a 15-year-old female with atypical WS. The patient presented with developmental delay, profound bilateral sensorineural hearing loss, heterochromia iridis, hypotonia, and bilateral finger contractures. Published genomic and phenotypic profiles of patients with SOX10-encompassing deletions point toward several plausible candidate gene that could account for the considerable clinical heterogeneity. These studies suggest the existence of modifiers among the co-deleted, dosage-sensitive genes (e.g., MYH9) and among genes whose effect may depend on the unmasking of recessive mutations (e.g., PLA2G6). Finally, we highlight evidence illustrating extensive interconnectivity of SOX10-hypothesizing that haploinsufficiency of SOX10 may "unmask" subtler effects on expression or epistasis associated with variants in SOX10 targets (e.g., DHH), in its partners (e.g., PAX3, EGR2), and in genes with functional overlap (e.g., SOX8, SOX9).

    The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome) is a rare autosomal dominant syndrome caused due to mutations in the patched gene found on chromosome arm 9 q. It shows high penetrance and variable expressivity; is characterized by basal cell carcinomas, odontogenic keratocysts, palmar and/or plantar pits and ectopic calcifications of the falx cerebri. Until date, very few cases of GGS have been reported in India. Early diagnosis and treatment as well as genetic counseling are essential for this syndrome. A rare case report of a patient with characteristic features of GGS diagnosed at a rural dental college of Gujarat, India is presented here. This case report draws attention of the valuable role of dentist in diagnosis and early management of this syndrome.

    Hemolytic uremic syndrome (HUS) is a clinical syndrome characterized by the triad of thrombotic microangiopathy, thrombocytopenia, and acute kidney injury. Hemolytic uremic syndrome represents a heterogeneous group of disorders with variable etiologies that result in differences in presentation, management and outcome. In recent years, better understanding of the HUS, especially those due to genetic mutations in the alternative complement pathway have provided an update on the terminology, classification, and treatment of the disease. This review will provide the updated classification of the disease and the current diagnostic and therapeutic approaches on the complement-mediated HUS in addition to STEC-HUS which is the most common cause of the HUS in childhood.

    2015-01-01

    Basal cell nevus syndrome (BCNS) or Gorlin syndrome is a rare neurocutaneous syndrome sometimes known as the fifth phacomatosis, inherited in autosomal dominant fashion with complete penetrance and variable expressivity. Gorlin syndrome is characterized by development of multiple basal cell carcinomas (BCCs), jaw cysts, palmar or plantar pits, calcification of falx cerebri, various developmental skeletal abnormalities such as bifid rib, hemi- or bifid vertebra and predisposition to the development of various tumors. BCNS is caused by a mutation in the PTCH1 gene localized to 9q22.3. Its estimated prevalence varies between 1/55600 and 1/256000 with an equal male to female ratio. The medulloblastoma variant seen in Gorlin syndrome patients is of the desmoplastic type, characteristically presenting during the first 3 years of life. Therefore, children with desmoplastic medulloblastoma should be carefully screened for other features of BCNS. Radiation therapy for desmoplastic medulloblastoma should be avoided in BCNS patients as it may induce development of invasive BCCs and other tumors in the skin area exposed to radiation. This syndrome is a multisystem disorder so involvement of multiple specialists with a multimodal approach to detect and treat various manifestations at early stages will reduce the long-term sequelae and severity of the condition. Life expectancy is not significantly altered but morbidity from complications and cosmetic scarring can be substantial.

    1998-06-22

    Klinefelter syndrome is the most common sex chromosome disorder. Affected males carry an additional X chromosome, which results in male hypogonadism, androgen deficiency, and impaired spermatogenesis. Some patients may exhibit all of the classic signs of this disorder, including gynecomastia, small testes, sparse body hair, tallness, and infertility, whereas others, because of the wide variability in clinical expression, lack many of these features. Treatment consists of testosterone replacement therapy to correct the androgen deficiency and to provide patients with appropriate virilization. This therapy also has positive effects on mood and self-esteem and has been shown to protect against osteoporosis, although it will not reverse infertility. Although the diagnosis of Klinefelter syndrome is now made definitively using chromosomal karyotyping, revealing in most instances a 47,XXY genotype, the diagnosis also can be made using a careful history and results of a physical examination, with the hallmark being small, firm testes. As it affects 1 in 500 male patients and presents with a variety of clinical features, primary care physicians should be familiar with this condition.

    Chronic intestinal pseudoobstruction syndrome is a rare clinical condition in which impaired intestinal peristalsis causes recurrent symptoms of bowel obstruction in the absence of a mechanical occlusion. This syndrome may involve variable segments of small or large bowel, and may be associated with urinary bladder retention. This study included 6 children(3 boys and 3 girls) of chronic intestinal obstruction. Four were symptomatic at birth and two were of the ages of one month and one year. All had abdominal distension and deflection difficulty. Five had urinary bladder distension. Despite parenteral nutrition and surgical intervention(ileostomy or colostomy), bowel obstruction persisted and four patients expired from sepses within one year. All had gaseous distension of small and large bowel on abdominal films. In small bowel series, consistent findings were variable degree of dilatation, decreased peristalsis(prolonged transit time) and microcolon or microrectum. This disease entity must be differentiated from congenital megacolon, ileal atresia and megacystis syndrome.

    Full Text Available Abstract LEOPARD syndrome (LS, OMIM 151100 is a rare multiple congenital anomalies condition, mainly characterized by skin, facial and cardiac anomalies. LEOPARD is an acronym for the major features of this disorder, including multiple Lentigines, ECG conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth, and sensorineural Deafness. About 200 patients have been reported worldwide but the real incidence of LS has not been assessed. Facial dysmorphism includes ocular hypertelorism, palpebral ptosis and low-set ears. Stature is usually below the 25th centile. Cardiac defects, in particular hypertrophic cardiomyopathy mostly involving the left ventricle, and ECG anomalies are common. The lentigines may be congenital, although more frequently manifest by the age of 4–5 years and increase throughout puberty. Additional common features are café-au-lait spots (CLS, chest anomalies, cryptorchidism, delayed puberty, hypotonia, mild developmental delay, sensorineural deafness and learning difficulties. In about 85% of the cases, a heterozygous missense mutation is detected in exons 7, 12 or 13 of the PTPN11 gene. Recently, missense mutations in the RAF1 gene have been found in two out of six PTPN11-negative LS patients. Mutation analysis can be carried out on blood, chorionic villi and amniotic fluid samples. LS is largely overlapping Noonan syndrome and, during childhood, Neurofibromatosis type 1-Noonan syndrome. Diagnostic clues of LS are multiple lentigines and CLS, hypertrophic cardiomyopathy and deafness. Mutation-based differential diagnosis in patients with borderline clinical manifestations is warranted. LS is an autosomal dominant condition, with full penetrance and variable expressivity. If one parent is affected, a 50% recurrence risk is appropriate. LS should be suspected in foetuses with severe cardiac hypertrophy and prenatal DNA test may be performed. Clinical management should

    Ulnar tunnel syndrome could be broadly defined as a compressive neuropathy of the ulnar nerve at the level of the wrist. The ulnar tunnel, or Guyon's canal, has a complex and variable anatomy. Various factors may precipitate the onset of ulnar tunnel syndrome. Patient presentation depends on the anatomic zone of ulnar nerve compression: zone I compression, motor and sensory signs and symptoms; zone II compression, isolated motor deficits; and zone III compression; purely sensory deficits. Conservative treatment such as activity modification may be helpful, but often, surgical exploration of the ulnar tunnel with subsequent ulnar nerve decompression is indicated.

    2012-05-01

    Treacher Collins syndrome is a congenital syndrome with characteristic craniofacial malformations, which are well described in the literature. However, the presence of cervical spine dysmorphology in this syndrome has been minimally described. This study reviews cervical spine radiographs of 40 patients with Treacher Collins syndrome. In this sample, 7 of 40 patients displayed cervical spine anomalies, with 3 of these patients displaying multiple cervical spine anomalies. The patterns of spinal anomalies were variable, suggesting that the underlying genetic mutation has variable expressivity in cervical spine development as it does elsewhere in the craniofacial skeleton.

    Refeeding syndrome is a complex syndrome that occurs as a result of reintroducing nutrition (oral, enteral or parenteral) to patients who are starved or malnourished. Patients can develop fluid-balance abnormalities, electrolyte disorders (hypophosphataemia, hypokalaemia and hypomagnesaemia), abnormal glucose metabolism and certain vitamin deficiencies. Refeeding syndrome encompasses abnormalities affecting multiple organ systems, including neurological, pulmonary, cardiac, neuromuscular and haematological functions. Pathogenic mechanisms involved in the refeeding syndrome and clinical manifestations have been reviewed. We provide suggestions for the prevention and treatment of refeeding syndrome. The most important steps are to identify patients at risk, reintroduce nutrition cautiously and correct electrolyte and vitamin deficiencies properly.

    Metabolic syndrome, which is consisted of hypertension, dyslipidemia and impaired glucose tolerance, is one of the most significant lifestyle-related disorders that lead to cardiovascular diseases. Among many upstream factors that are related to metabolic syndrome, obesity, especially visceral obesity, plays an essential role in its pathogenesis. In recent studies, possible mechanisms which connect obesity to metabolic syndrome have been elucidated, such as inflammation, abnormal secretion of adipokines and mitochondrial dysfunction. In this review, we focus on the relationship between obesity and metabolic syndrome; and illustrate how visceral obesity contributes to, and how the treatments for obesity act on metabolic syndrome.

  14. The impact of temporal variability of biochemical markers PAPP-A and free β-hCG on the specificity of the first-trimester Down syndrome screening: a Croatian retrospective study

    Science.gov (United States)

    2010-01-01

    Background The variability of maternal serum biochemical markers for Down syndrome, free β-hCG and PAPP-A can have a different impact on false-positive rates between the 10+0 and 13+6 week of gestation. The study population comprised 2883 unaffected, singleton, spontaneously conceived pregnancies in Croatian women, who delivered apparently healthy child at term. Women were separated in 4 groups, dependently on the gestational week when the analyses of biochemical markers were performed. The concentrations of free β-hCG and PAPP-A in maternal serum were determined by solid-phase, enzyme-labeled chemiluminiscent immunometric assay (Siemens Immulite). Concentrations were converted to MoMs, according to centre-specific weighted regression median curves for both markers in unaffected pregnancies. The individual risks for trisomies 21, 18 and 13 were computed by Prisca 4.0 software. Findings There were no significant differences between the sub-groups, regarding maternal age, maternal weight and the proportion of smokers. The difference in log10 MoM free β-hCG values, between the 11th and 12th gestational week, was significant (p = 0.002). The difference in log10 MoM PAPP-A values between the 11th and 12th, and between 12th and 13th week of gestation was significant (p = 0.006 and p = 0.003, respectively). False-positive rates of biochemical risk for trisomies were 16.1% before the 11th week, 12.8% in week 12th, 11.9% in week 13th and 9.9% after week 13th. The differences were not statistically significant. Conclusions Biochemical markers (log10 MoMs) showed gestation related variations in the first-trimester unaffected pregnancies, although the variations could not be attributed either to the inaccuracy of analytical procedures or to the inappropriately settled curves of median values for the first-trimester biochemical markers.

    Full Text Available Abstract The Greig cephalopolysyndactyly syndrome (GCPS is a pleiotropic, multiple congenital anomaly syndrome. It is rare, but precise estimates of incidence are difficult to determine, as ascertainment is erratic (estimated range 1–9/1,000,000. The primary findings include hypertelorism, macrocephaly with frontal bossing, and polysyndactyly. The polydactyly is most commonly preaxial of the feet and postaxial in the hands, with variable cutaneous syndactyly, but the limb findings vary significantly. Other low frequency findings include central nervous system (CNS anomalies, hernias, and cognitive impairment. GCPS is caused by loss of function mutations in the GLI3 transcription factor gene and is inherited in an autosomal dominant pattern. The disorder is allelic to the Pallister-Hall syndrome and one form of the acrocallosal syndrome. Clinical diagnosis is challenging because the findings of GCPS are relatively non-specific, and no specific and sensitive clinical have been delineated. For this reason, we have proposed a combined clinical-molecular definition for the syndrome. A presumptive diagnosis of GCPS can be made if the patient has the classic triad of preaxial polydactyly with cutaneous syndactyly of at least one limb, hypertelorism, and macrocephaly. Patients with a phenotype consistent with GCPS (but which may not manifest all three attributes listed above and a GLI3 mutation may be diagnosed definitively with GCPS. In addition, persons with a GCPS-consistent phenotype who are related to a definitively diagnosed family member in a pattern consistent with autosomal dominant inheritance may be diagnosed definitively as well. Antenatal molecular diagnosis is technically straightforward to perform. Differential diagnoses include preaxial polydactyly type 4, the GCPS contiguous gene syndrome, acrocallosal syndrome, Gorlin syndrome, Carpenter syndrome, and Teebi syndrome.

    2009-06-01

    In its strict sense, the term "autoinflammatory syndromes" comprises the hereditary periodic fever syndromes (HPF), which are caused by mutations of pattern-recognition receptors (PRR) and perturbations of the cytokine balance. These include the crypyrinopathies, familial Mediterranean fever, TNF-receptor associated periodic fever syndrome (TRAPS), hyper-IgD and periodic syndrome (HIDS), pyogenic sterile arthritis, pyoderma gangrenosum and acne (PAPA) syndrome, NALP12-HPF, and the Blau syndrome. The diseases are characterized by spontaneous activation of cells of the innate immunity in the absence of ligands. Autoantibodies are usually not found. HPF clinically present with recurrent fever episodes and inflammation, especially of serosal and synovial interfaces and the skin. Intriguingly, PRR-mediated autoinflammtory mechanisms also play a role in a number of chronic inflammatory and autoimmune diseases.

    Objective: To construct a graphical model which can illustrate relational structures among functioning variables of polycystic ovary syndrome (PC OS), and to find new supports for clinic and academic practices of PC OS pati enter rehabilitation. Method: Fifty-seven PCOS patients with obesity or overweight participated in this study. The 109 categories of obesity comprehensive International Classification of Functioning, Disability and Health ICF core sets were defined as variables during graphical modeling. The "least absolute shrinkage and selection operator** was used for mining conditional dependencies among the variables. Bootstrap resampling method and confidence interval approach were used to enhance the stability of models. R software and Pajek 2.04 were used for graphical modeling. For analyzing the final model, component analysis, clustering analysis and k-core decomposition were carried out by using both of the Pajek 2.04 and Ucinet 6360. Result: In the selected graph model, there were 17 pairs of categories. Each pair contained two interconnected categories. There were other 31 interconnected categories which organized into the maximal independent compo-nent in the final model. In the main component the b650 (menstruation function) was connected with b555 (endocrine gland function) and e580 (health service, system and policie). The b555 also related to s580 (structure of endocrine glands), s630 (structure of reproductive system), e455 (individual attitudes of other professionals) and e465 (social norm, practice and ideology). Markov clustering analysis for this main component revealed 10 clusters. The bl26 (temperament and personality function) was the most powerful category in the entire model, the cluster which belonged to was also the most influential cluster. Conclusion: There were complex relational structures among functioning variables in PCOS. The graphical modeling could reveal its characteristics which had clinical evidences and provide clues

    Full Text Available The Metabolic syndrome is a widely prevalent and multi-factorial disorder. The syndrome has been given several names, including- the metabolic syndrome, the insulin resistance syndrome, the plurimetabolic syndrome, and the deadly quartet. With the formulation of NCEP/ATP III guidelines, some uniformity and standardization has occurred in the definition of metabolic syndrome and has been very useful for epidemiological purposes. The mechanisms underlying the metabolic syndrome are not fully known; however resistance to insulin stimulated glucose uptake seems to modify biochemical responses in a way that predisposes to metabolic risk factors. The clinical relevance of the metabolic syndrome is related to its role in the development of cardiovascular disease. Management of the metabolic syndrome involves patient-education and intervention at various levels. Weight reduction is one of the main stays of treatment. In this article we comprehensively discuss this syndrome- the epidemiology, pathogenesis, clinical relevance and management. The need to do a comprehensive review of this particular syndrome has arisen in view of the ever increasing incidence of this entitiy. Soon, metabolic syndrome will overtake cigarette smoking as the number one risk factor for heart disease among the US population. Hardly any issue of any primary care medical journal can be opened without encountering an article on type 2 diabetes, dyslipidemia or hypertension. It is rare to see type 2 diabetes, dyslipidemia, obesity or hypertension in isolation. Insulin resistance and resulting hyperinsulinemia have been implicated in the development of glucose intolerance (and progression to type 2 diabetes, hypertriglyceridemia, hypertension, polycystic ovary yndrome, hypercoagulability and vascular inflammation, as well as the eventual development of atherosclerotic cardiovascular disease manifested as myocardial infarction, stroke and myriad end organ diseases.

    2014-04-01

    The clinical classification of Robinow-Sorauf syndrome has changed over the last few decades. Robinow-Sorauf syndrome is characterized by facies similar to those of Saethre-Chotzen syndrome with bifid or partially duplicated halluces. The current outlook is that the 'Robinow-Sorauf' families are examples of variable expression of the TWIST mutant phenotype and that the 'Robinow-Sorauf' syndrome lies within the spectrum of the Saethre-Chotzen syndrome. We present a case of 19-year-old female patient exhibiting classical clinical and radiological features of Robinow-Sorauf phenotype of Saethre-Chotzen syndrome. A brief review of previously reported cases and nosology has been presented.

    Clarke Sarah LN

    2013-02-01

    Full Text Available Abstract First described in 1983, Barth syndrome (BTHS is widely regarded as a rare X-linked genetic disease characterised by cardiomyopathy (CM, skeletal myopathy, growth delay, neutropenia and increased urinary excretion of 3-methylglutaconic acid (3-MGCA. Fewer than 200 living males are known worldwide, but evidence is accumulating that the disorder is substantially under-diagnosed. Clinical features include variable combinations of the following wide spectrum: dilated cardiomyopathy (DCM, hypertrophic cardiomyopathy (HCM, endocardial fibroelastosis (EFE, left ventricular non-compaction (LVNC, ventricular arrhythmia, sudden cardiac death, prolonged QTc interval, delayed motor milestones, proximal myopathy, lethargy and fatigue, neutropenia (absent to severe; persistent, intermittent or perfectly cyclical, compensatory monocytosis, recurrent bacterial infection, hypoglycaemia, lactic acidosis, growth and pubertal delay, feeding problems, failure to thrive, episodic diarrhoea, characteristic facies, and X-linked family history. Historically regarded as a cardiac disease, BTHS is now considered a multi-system disorder which may be first seen by many different specialists or generalists. Phenotypic breadth and variability present a major challenge to the diagnostician: some children with BTHS have never been neutropenic, whereas others lack increased 3-MGCA and a minority has occult or absent CM. Furthermore, BTHS was first described in 2010 as an unrecognised cause of fetal death. Disabling mutations or deletions of the tafazzin (TAZ gene, located at Xq28, cause the disorder by reducing remodeling of cardiolipin, a principal phospholipid of the inner mitochondrial membrane. A definitive biochemical test, based on detecting abnormal ratios of different cardiolipin species, was first described in 2008. Key areas of differential diagnosis include metabolic and viral cardiomyopathies, mitochondrial diseases, and many causes of neutropenia and

    2012-01-01

    Full Text Available The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS, is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the odontogenic keratocysts are usually one of the first manifestations of the syndrome. This case report presents a patient diagnosed as NBCCS by clinical, radiographic and histological findings in a 13-year-old boy. This paper highlights the importance of early diagnosis of NBCCS which can help in preventive multidisciplinary approach to provide a better prognosis for the patient.

    2011-01-01

    The paper addresses the issue of organizational climate and burnout syndrome. It has been assumed that burnout syndrome is dependent on work climate (organizational climate), therefore, two concepts were analyzed: by D. Kolb (organizational climate) and by Ch. Maslach (burnout syndrome). The research involved 239 persons (122 woman, 117 men), aged 21-66. In the study Maslach Burnout Inventory (MBI) and Inventory of Organizational Climate were used. The results of statistical methods (correlation analysis, one-variable analysis of variance and regression analysis) evidenced a strong relationship between organizational climate and burnout dimension. As depicted by the results, there are important differences in the level of burnout between the study participants who work in different types of organizational climate. The results of the statistical analyses indicate that the organizational climate determines burnout syndrome. Therefore, creating supportive conditions at the workplace might reduce the risk of burnout.

    Hubris syndrome is associated with power, more likely to manifest itself the longer the person exercises power and the greater the power they exercise. A syndrome not to be applied to anyone with existing mental illness or brain damage. Usually symptoms abate when the person no longer exercises power. It is less likely to develop in people who retain a personal modesty, remain open to criticism, have a degree of cynicism or well developed sense of humour. Four heads of government in the last 100 years are singled out as having developed hubris syndrome: David Lloyd George, Margaret Thatcher, George W Bush and Tony Blair.

    2011-10-01

    Full Text Available Abstract Neuroacanthocytosis (NA syndromes are a group of genetically defined diseases characterized by the association of red blood cell acanthocytosis and progressive degeneration of the basal ganglia. NA syndromes are exceptionally rare with an estimated prevalence of less than 1 to 5 per 1'000'000 inhabitants for each disorder. The core NA syndromes include autosomal recessive chorea-acanthocytosis and X-linked McLeod syndrome which have a Huntington´s disease-like phenotype consisting of a choreatic movement disorder, psychiatric manifestations and cognitive decline, and additional multi-system features including myopathy and axonal neuropathy. In addition, cardiomyopathy may occur in McLeod syndrome. Acanthocytes are also found in a proportion of patients with autosomal dominant Huntington's disease-like 2, autosomal recessive pantothenate kinase-associated neurodegeneration and several inherited disorders of lipoprotein metabolism, namely abetalipoproteinemia (Bassen-Kornzweig syndrome and hypobetalipoproteinemia leading to vitamin E malabsorption. The latter disorders are characterized by a peripheral neuropathy and sensory ataxia due to dorsal column degeneration, but movement disorders and cognitive impairment are not present. NA syndromes are caused by disease-specific genetic mutations. The mechanism by which these mutations cause neurodegeneration is not known. The association of the acanthocytic membrane abnormality with selective degeneration of the basal ganglia, however, suggests a common pathogenetic pathway. Laboratory tests include blood smears to detect acanthocytosis and determination of serum creatine kinase. Cerebral magnetic resonance imaging may demonstrate striatal atrophy. Kell and Kx blood group antigens are reduced or absent in McLeod syndrome. Western blot for chorein demonstrates absence of this protein in red blood cells of chorea-acanthocytosis patients. Specific genetic testing is possible in all NA syndromes

    Jerusalem's psychiatrists expect to encounter, as the millennium approaches, an ever-increasing number of tourists who, upon arriving in Jerusalem, may suffer psychotic decompensation. To describe the Jerusalem syndrome as a unique acute psychotic state. This analysis is based on accumulated clinical experience and phenomenological data consisting of cultural and religious perspectives. Three main categories of the syndrome are identified and described, with special focus on the category pertaining to spontaneous manifestations, unconfounded by previous psychotic history or psychopathology. The discrete form of the Jerusalem syndrome is related to religious excitement induced by proximity to the holy places of Jerusalem, and is indicated by seven characteristic sequential stages.

    Hereditary periodic (fever) syndromes, also called autoinflammatory syndromes, are characterized by relapsing fever and additional manifestations such as skin rashes, mucosal manifestations, or joint symptoms. Some of these disorders present with organ involvement and serological signs of inflammation without fever. There is a strong serological inflammatory response with an elevation of serum amyloid A (SAA), resulting in an increased risk of secondary amyloidosis. There are monogenic disorders (familial mediterranean fever (FMF), hyper-IgD-syndrome (HIDS), cryopyrin-associated periodic syndromes (CAPS), "pyogenic arthritis, acne, pyoderma gangrenosum" (PAPA), and "pediatric granulomatous arthritis (PGA) where mutations in genes have been described, which in part by influencing the function of the inflammasome, in part by other means, lead to the induction of the production of IL-1β. In "early-onset of enterocolitis (IBD)", a functional IL-10 receptor is lacking. Therapeutically, above all, the IL-1 receptor antagonist anakinra is used. In case of TRAPS and PGA, TNF-antagonists (etanercept) may also be used; in FMF colchicine is first choice. As additional possible autoinflammatory syndromes, PFAPA syndrome (periodic fever with aphthous stomatitis, pharyngitis and adenitis), Schnitzler syndrome, Still's disease of adult and pediatric onset, Behçet disease, gout, chronic recurrent multifocal osteomyelitis (CRMO) and Crohn's disease also are mentioned.

    Despite being known more than 60 years, refeeding syndrome (RS) still bears many uncertainties. For example, its definition is not clear and definite, and the attitude to it varies from the complete neglect to over-prevention.The term "refeeding syndrome" refers to electrolyte and metabolic changes occurring in malnourished patients after the readministration of nutrition. These changes concern especially to phosphates and ions. Potassium, magnesium, naturism and fluids balance are involved. The changes lead to cell energetic metabolism and electric potential disturbances, with related clinical symptoms.Fully developed refeeding syndrome is quite rare; nevertheless it can be fatal for the patient. However, even its development can lead to many complications increasing the patient's morbidity and the length of stay in the hospital. Yet the refeeding syndrome is more or less predictable and if kept in mind also preventable.The aim of this article is to get the reader to know more about this metabolic phenomenon and possible attitudes towards it.

    The autoinflammatory disorders are a new and expanding classification of inflammatory diseases characterized by recurrent episodes of systemic inflammation in the absence of pathogens, autoantibodies or antigen specific T cells. These disorders are caused by primary dysfunction of the innate immune system, without evidence of adaptive immune dysregulation. Innate immune abnormalities include aberrant responses to pathogen associated molecular patterns (PAMPs) like lipopolysaccharide and peptidoglycan, prominent neutrophilia in blood and tissues, and dysregulation of inflammatory cytokines (IL-1beta, TNF-alpha) or their receptors. The autoinflammatory diseases comprise both hereditary (Familial Mediterranean Fever, FMF; Mevalonate Kinase Deficiency, MKD; TNF Receptor Associated Periodic Syndrome, TRAPS; Cryopyrin Associated Periodic Syndrome, CAPS; Blau syndrome; Pyogenic sterile Arthritis, Pyoderma gangrenosum and Acne syndrome, PAPA; Chronic Recurrent Multifocal Osteomyelitis, CRMO) and multifactorial (Crohn's and Behçet's diseases) disorders.

    Ellis-van Creveld (EVC) syndrome or chondroectodermal dysplasia is a rare autosomal recessive disorder characterized by a variable spectrum of clinical findings. Classical EVC syndrome comprises a tetrad of clinical manifestations of chondrodystrophy, polydactyly, ectodermal dysplasia, and cardiac defects. In several case reports, dysplasia involving other organs has also been identified. Hematologic abnormalities have been rarely reported in patients with EVC syndrome. Here, we report a case of a 3-year-old Hispanic boy with EVC syndrome and marked dyserythropoiesis. The dyserythropoiesis may be part of an isolated myelodysplastic change or a primary myelodysplastic syndrome and likely represents an unusual EVC syndrome association. To our knowledge, this association has not been previously reported.

    SAPHO syndrome is a disorder characterized by Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis. As the osteoarticular and skin manifestations often do not occur simultaneously and there are no validated diagnostic criteria, the diagnosis can be difficult. Clinical and imaging investigation is necessary to establish the many differential diagnoses of SAPHO syndrome. The etiopathogenesis involves infectious (probably Propionibacterium acnes), immunologic, and genetic factors. Treatment is based on information gathered from case reports and small series, and is related to specific skin or articular symptoms.

    2009-01-01

    Carpenter syndrome is a rare autosomal recessive disorder that belongs to a group of rare craniosynostosis syndromes (Bull Soc Med Paris 1906;23:1310). Carpenter syndrome is the rarest, with only occasional patients seen. There are 3 common features in all of these syndromes: craniosynostosis (skull base abnormalities, with early fusion in different sutures), midface hypoplasia, and musculoskeletal abnormalities. Clinical features of Carpenter syndrome include peculiar facies, asymmetry of the skull, polydactyly, brachymesophalangy, mild soft tissue syndactyly, obesity, hypogenitalism, congenital heart disease, and mental retardation (J Pediatr 1966;69:1; Am J Roentgenol 1969;106). The brachycephaly is caused by early fusion in the coronal, sagittal, and lambdoidal sutures (Proc R Soc Med Sect Study Dis Child 1909). Most of the affected patients have a surgical procedure between 3 to 9 months of age to open the cranial vault to make space for the brain to grow (Plast Reconstr Surg 1978;62:335). We present a patient with Carpenter syndrome who is unusual in that she is an adult who has never had surgical intervention.

  7. Behcet's Syndrome.

    2012-12-03

    Behcet's syndrome (BS) is a vasculitis, seen more commonly around the Mediterranean and the Far East, and manifests with oral and genital ulcerations, skin lesions, uveitis, and vascular, central nervous system and gastrointestinal involvement. Its natural history of getting less severe over time, more severe disease in males and lack of specific diagnostic testing separates it from other commonly seen conditions in rheumatology. Most of the serious manifestations respond well to immunosuppression, and these are the mainstays of treatment for BS. BS is more prevalent in regions along the Silk Road, from the Mediterranean to the Far East. The genetic risk factor most strongly associated with BS is the human leukocyte antigen (HLA)-B51 allele. While genetic factors seem to play a role in the development of certain features of BS, there is general consensus that as yet unidentified environmental stimuli are necessary for initiation of disease. Proposed exogenous triggers include both bacterial and viral infections, which may then lead to dysregulation of the immune system, ultimately leading to the phenotypic expression of disease. The clinical manifestations of BS are protean in nature. While most patients develop mucocutaneous and genital ulcers along with eye disease, other patients may also present with arthritis, frank vasculitis, thrombophlebitis and CNS disease. Interestingly, the manifestations of this illness vary considerably based on gender and ethnicity. As the phenotypic expression among patients with BS is quite heterogeneous, pharmacological therapy is variable and dependent upon the severity of the disease as well as organ involvement. Treatment for BS overlaps considerably with therapies for other autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis and the vasculitides. Pharmacological agents utilized for treatment of BS include corticosteroids, colchicine, azathioprine, and tumour necrosis factor (TNF).α inhibitors

    Full Text Available Objective: The purpose of the study was to detect & evaluate the feto-maternal outcome of HELLP syndrome & partial HELLP syndrome among preeclamptic mothers. Materials and methods: This cross sectional observational study analysed feto-maternal outcome in 44 patients with HELLP syndrome and 32 patients with partial HELLP syndrome and compared with 556 patients having preeclampsia without features of HELLP syndrome. Results: 600 patients were included in this study. The prevalence of HELLP syndrome and partial HELLP syndrome were found to be 7.3% and 5.3% respectively in preeclampsia. The systolic blood pressure, gestational age at admission and during delivery, haematological and biochemical variables, rate of spontaneous vaginal delivery and type of anaesthesia were significantly different in HELLP syndrome and partial HELLP syndrome than in the preeclampsia group. There were statistically significant difference in perinatal outcome like birth weight, intrauterine death, neonatal death, and admission in NICU. Eclampsia was significantly increased in both HELLP syndrome and partial HELLP syndrome. Conclusion: Both HELLP and partial HELLP syndrome must be diagnosed as soon as possible in pregnant or post partum women with preeclampsia. HELLP syndrome is severe than preeclampsia in terms of maternal and perinatal outcome. Partial HELLP syndrome is almost as grave as HELLP syndrome.

    2008-11-01

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Full Text Available Ehlers-Danlos syndrome (EDS is a generalized disorder of one element of connective tissue manifesting clinically by fragility and hyperelasticity of the skin and joint laxity. It is a hereditary disorder, the inheritance being usually autosomal dominant with low penetrance. Autosomal recessive and X-linked recessive varieties are also known. First described by Hippocrates in 4 th century B.C., the various clinical types with variable penetrance have been described lately. The number of cases EDS reported in the literature is very meagre. With the available information only about six publications of classic EDS in siblings had been reported in Indian literature.

    Full Text Available Griscelli syndrome (GS is a rare autosomal recessive multisystem disorder of pigmentary dilution of skin, silver gray hair, variable immunodeficiency, neurological impairment, and abnormal accumulation of melanosomes in melanocytes. GS type 3 is characterized by hypomelanosis with no immunological and neurological manifestation. Prognosis is very good in type 3 GS and usually require no active intervention, as opposed to type 1 and 2 where early diagnosis and treatment plays a crucial role in patient's survival. The characteristic phenotypic appearance, especially the pigment dilution of the patient's hair, is emphasized here.

  1. Pfeiffer syndrome

    2006-06-01

    Full Text Available Abstract Pfeiffer syndrome is a rare autosomal dominantly inherited disorder that associates craniosynostosis, broad and deviated thumbs and big toes, and partial syndactyly on hands and feet. Hydrocephaly may be found occasionally, along with severe ocular proptosis, ankylosed elbows, abnormal viscera, and slow development. Based on the severity of the phenotype, Pfeiffer syndrome is divided into three clinical subtypes. Type 1 "classic" Pfeiffer syndrome involves individuals with mild manifestations including brachycephaly, midface hypoplasia and finger and toe abnormalities; it is associated with normal intelligence and generally good outcome. Type 2 consists of cloverleaf skull, extreme proptosis, finger and toe abnormalities, elbow ankylosis or synostosis, developmental delay and neurological complications. Type 3 is similar to type 2 but without a cloverleaf skull. Clinical overlap between the three types may occur. Pfeiffer syndrome affects about 1 in 100,000 individuals. The disorder can be caused by mutations in the fibroblast growth factor receptor genes FGFR-1 or FGFR-2. Pfeiffer syndrome can be diagnosed prenatally by sonography showing craniosynostosis, hypertelorism with proptosis, and broad thumb, or molecularly if it concerns a recurrence and the causative mutation was found. Molecular genetic testing is important to confirm the diagnosis. Management includes multiple-staged surgery of craniosynostosis. Midfacial surgery is performed to reduce the exophthalmos and the midfacial hypoplasia.

    Full Text Available We report a case of a fifty-year-old male who was admitted with a three month history of increasing weakness, prostration, decreasing appetite and inability to swallow. The patient was a chronic alcoholic, unemployed, and of very poor socioeconomic background. The patient was initially investigated for upper GI malignancy, Addisons disease, bulbar palsy and other endocrinopathies. Concurrent management was started for severe electrolyte abnormalities and enteral nutritional supplementation was begun. By the fourth day of feeding patient developed severe hypophosphatemia and other life-threatening features suggesting refeeding syndrome. The patient was managed for the manifestations of refeeding syndrome. A final diagnosis of chronic alcoholic malnutrition with refeeding syndrome was made. Refeeding of previously starving patients may lead to a variety of complications including sudden death.

    The compartment syndrome is defined as a condition in which high pressure within a closed fascial space (muscle compartment) reduces capillary blood perfusion below the level necessary for tissue viability'. This condition occurs in acute and chronic (exertional) forms, and may be secondary to a variety of causes. The end-result of an extended period of elevated intramuscular pressure may be the development of irreversible tissue injury and Volkmann's contracture. The goal of treatment of the compartment syndrome is the reduction of intracompartmental pressure thus facilitating reperfusion of ischaemic tissue and this goal may be achieved by decompressive fasciotomy. Controversy exists regarding the critical pressure-time thresholds for surgical decompression and the optimal diagnostic methods of measuring intracompartmental pressures. This paper will update and review some current knowledge regarding the pathophysiology, aetiology, diagnosis, and treatment of the acute compartment syndrome.

    The objective of this article is to review microcephaly from a genetics point of view, especially with regard to the process of identification of syndromes in which small head circumference occurs. Microcephaly can be due to either genetic or environmental causes. It can be the only positive finding or may be part of a syndrome of congenital anomalies. The genetic etiology can be caused by autosomal dominant, autosomal recessive, or X-linked genes or various types of chromosome anomalies. Some of the gene mutations have been identified recently. Syndromic microcephaly is associated with a large number of conditions. Some can be diagnosed, or at least suspected, based on their characteristic facial dysmorphism, and others can be searched for using databases of genetic disorders.

    2013-02-01

    Full Text Available Postconcussional syndrome is characterized by somatic, cognitive and psychiatric (emotional, behavioral symptoms that occurs after mild traumatic brain injury. It has been known that these symptoms recover fully within 3-6 months almost in 90% of patients. Although its etiology is still controversial, biological, psychological and social factors may account for the development and continuation of the symptoms. Diagnosis is based on the subjective complaints. To find out an objective method for definite diagnosis, trials searching for both neuroimaging and specific serum biomarkers stil continue. The treatment of the syndrome is mainly of palliative nature. Information, education, reassurance and multifaceted rehabilitation programmes can be beneficial. There are promising trials reporting the effectiveness of cognitive behavioral therapy in the treatment of postconcussional syndrome. [Archives Medical Review Journal 2013; 22(1.000: 96-109

Most cases (18/26; 69%) were registered in the western part of Europe, where...... was particularly high (42%). Most cases of Fraser syndrome (85%) are suspected prenatally, often due to the presence of the association of renal agenesis and cryptophthalmos.

    2002-10-01

    The serotonin syndrome is a hyperserotoninergic state resulting from an excess of intrasynaptic 5-hydroxytryptamine, induced by multiple psychotropic agents, but also non psychiatric drugs. It is a potentially dangerous and sometimes lethal condition. The clinical manifestations usually include cognitive, neuromuscular and autonomic features and are mediated by the action of serotonin on various subtypes of receptors. The main differential diagnosis is the neuroleptic malignant syndrome. Treatment is mainly supportive. No pharmacological agent has been definitely demonstrated really effective. However, reports of cases treated with the 5-HT2 blockers, including cyproheptadine or chlorpromazine have suggested that these agents could have some efficacy. Serotonin syndrome is a toxic condition which requires heightened clinical awareness among physicians in order to prevent, recognize, and treat the condition promptly.

    2010-01-01

    Autoinflammatory syndromes (AIS) are a heterogeneous group of congenital diseases characterized by the presence of recurrent episodes of fever and local or generalized inflammation, in the absence of infectious agents, detectable auto-antibodies or antigen-specific autoreactive T-cells. These diseases have been much better understood during the past 15 years, mainly due to the marked advances of the Human Genoma Project and its implications in the identification and characterization of genetic mutations. In this paper we make a revision of the classification of AIS and focus our attention specially on the cryopyrin-associated periodic syndromes (CAPS), in particular the CINCA syndrome that shares many clinical characteristics with juvenile idiopathic arthritis.

    Full Text Available Metabolic Syndrome is a combination of risk factors including common etiopathogenesis. These risk factors play different roles in occurence of atherosclerotic diseases, type 2 diabetes, and cancers. Although a compromise can not be achieved on differential diagnosis for MS, the existence of any three criterias enable to diagnose MS. These are abdominal obesity, dislipidemia (hypertrigliceridemia, hypercholesterolemia, and reduced high density lipoprotein hypertension, and elevated fasting blood glucose. According to the results of Metabolic Syndrome Research (METSAR, the overall prevalence of MS in Turkey is 34%; in females 40%, and in males it is 28%. As a result of “Western” diet, and increased frequency of obesity, MS is observed in children and in adolescents both in the world and in Turkey. Resulting in chronic diseases, it is thought that the syndrome can be prevented by healthy lifestyle behaviours. [TAF Prev Med Bull 2010; 9(5.000: 535-540

  12. Eagle's Syndrome

    Pinheiro, Thaís Gonçalves

    2014-01-01

    Full Text Available Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical.

    Full Text Available Turner syndrome is a genetic disorder that affects mostly females. Affected females have characteristic features such as short stature, premature ovarian failure, and several other features. Oral manifestations of this condition are not much discussed in the literature. But reported literature includes teeth, palate, periodontal and salivary changes. So the aim of this review is to illustrate the general manifestations, and especially the oral manifestations of Turner syndrome and evaluate their possible management.

    Lemierre\\'s syndrome is a rare disease that results in an oropharyngeal infection, which precipitates an internal jugular vein thrombosis and metastatic infection. Fusobacterium necrophorum is an anaerobic Gram-negative bacillus and has been identified as the causative agent. We describe the case of a young girl whose presentation and diagnosis were confounded by a history of valvular heart disease. Infection of heart valves can produce many of the signs and symptoms associated with Lemierre\\'s syndrome. We describe the diagnosis, investigation and optimal management of this rare disorder.

    Full Text Available Olmsted syndrome is a rare disorder characterized by the combination of periorificial, keratotic plaques and bilateral palmoplantar keratoderma. New associated features are being reported. Olmsted syndrome is particularly rare in a female patient, and we report such a case in a six year-old Indian girl, who presented with keratoderma of her soles since birth and on her palms since the age of two years along with perioral and perinasal hyperkeratosis. She had sparse, light brown, thin hair. Although the psychomotor development of the child was normal until 18 months of age, the keratoderma plaques had restricted the child′s mobility after that stage.

    Loss of retroperitoneal fatty tissue as a result of a variety of debilitating conditions and noxa is believed to be the etiologic factor of superior mesenteric artery syndrome. A case of a 35 years old female patient with severe malnutrition and weight loss is presented, who developed superior mesenteric artery syndrome. Various theories of etiology, clinical course and treatment options of this uncommon disease are discussed. In our case, conservative management was inefficient, while surgical treatment aiming to bypass the obstruction by an anastomosis between the jejunum and the proximal duodenum (duodenojejunostomy) was successful. An interdisciplinary teamwork provides the most beneficial diagnostic and therapeutic result in this often underestimated disease.

The syndrome was characterized clinically by erythematous edema involving the forehead, glabella, and both eyelids, because of which the patient was not able to open completely his eyes. Furthermore, erythema and telangiectasiae were visible on the nose and cheeks. Laboratory and instrumental examinations were within normal ranges or negative. Histopathological examination showed dermal edema, perivascular and periadnexal lympho-histiocytic infiltrate, and sebaceous gland hyperplasia. Oral isotretinoin was ineffective despite the relatively long duration of the therapy (26 weeks).

    Cohen, D M; Green, J G; Miller, J; Gorlin, R J; Reed, J A

    1987-10-01

    Carpenter syndrome (ACPS type II) was first described by Carpenter in 1901. The syndrome consists of acrocephaly, soft tissue syndactyly, brachy- or agenesis mesophalangy of the hands and feet, preaxial polydactyly, congenital heart disease, mental retardation, hypogenitalism, obesity, and umbilical hernia. Here we review the literature on Carpenter syndrome and add 2 affected sibs with marked intrafamilial variability. This review showed that 2 reported variations of Carpenter syndrome, Goodman and Summitt syndromes, actually fall within the clinical spectrum of this disorder. This confirms earlier suggestions of Gorlin (personal communication 1982) and Hall et al [Am J Med Genet 5:423-434, 1980].

    Full Text Available Klinefelter syndrome is the most common sex chromosome disorder in males. Variation in clinical presentation and insufficient awareness of this syndrome among clinicians lead to fifty percent of patients remain undetected. Typical clinical features of Klinefelter syndrome are various degrees of hypogonadal symptoms, atrophic testes and gynaecomastia. However, these typical clinical symptoms may not be present in all patients. Even if serum testosterone levels are not markedly low, elevated serum follicle-stimulating hormone is a considerable laboratory finding. Definitive diagnosis is made by karyotype analysis of peripheral blood lymphocytes. It must be kept in mind that this analysis may be normal in rare conditions. Early recognition of patients during puberty and handling them as soon as possible is important. Testosterone replacement therapy results in increased muscle mass, bone mineral density and libido. The patient’s mood and self-esteem improve significantly. In general, patients with Klinefelter syndrome are accepted as infertile, however, assisted reproductive techniques may provide fertilization. Turk Jem 2013; 17: 63-7

    Bloom Syndrome (BS, MIM #210900) is an autosomal recessive genetic disorder caused by a mutation in the BLM gene, which codes for the DNA repair enzyme RecQL3 helicase. Without proper DNA repair mechanisms, abnormal DNA exchange takes place between sister chromatids and results in genetic instability that may lead to cancer, especially lymphoma and acute myelogenous leukemia, lower and upper gastrointestinal tract neoplasias, cutaneous tumors, and neoplasias in the genitalia and urinary tract. BS patients are usually of Ashkenazi Jewish descent and exhibit narrow facial features, elongated limbs, and several dermatologic complications including photosensitivity, poikiloderma, and telangiectatic erythema. The most concerning manifestation of BS is multiple malignancies, which require frequent screenings and strict vigilance by the physician. Therefore, distinguishing between BS and other dermatologic syndromes of similar presentation such as Rothmund-Thomson Syndrome, Erythropoietic Protoporphyria, and Cockayne Syndrome is paramount to disease management and to prolonging life. BS can be diagnosed through a variety of DNA sequencing methods, and genetic testing is available for high-risk populations. This review consolidates several sources on BS sequelae and aims to suggest the importance of differentiating BS from other dermatologic conditions. This paper also elucidates the recently discovered BRAFT and FANCM protein complexes that link BS and Fanconi anemia.

    The SAPHO syndrome, an acronym for synovitis, acne, pustulosis, hyperostosis and osteitis, is a rare disease which affects bones, joints and the skin. The main osteoarticular features are hyperostosis and osteitis. Osteoarticular symptoms predominantly occur on the anterior chest wall but the spine and the peripheral skeleton can also be involved. The most important skin affections are palmoplantar pustulosis and severe acne. The etiology of this syndrome remains unclear but infectious, immunological and genetic factors are involved. The diagnostic features of SAPHO syndrome are clinical and radiological. The most important diagnostic procedure is Tc-99 m bone scintigraphy but conventional x-rays as well as computed tomography (CT) and magnetic resonance imaging (MRI) can also contribute to the final diagnosis. Bone histology and positron emission tomography CT (PET-CT) may help to differentiate SAPHO syndrome from malignancies and infectious osteomyelitis. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the cornerstone of treatment. The results obtained using antibiotics and disease-modifying antirheumatic drugs (DMARDs), such as sulfasalazine and methotrexate are inconsistent. Bisphosphonates and anti-tumor necrosis factor (anti-TNF) drugs have shown promising results in small studies but further research is still necessary.

    Full Text Available Ellis-van Creveld syndrome also known as chondroectodermal dysplasia is a rare genetic disorder of the skeletal dysplasia type, first described by Richard WS Ellis and Simon van Creveld in 1940. The syndrome manifests with several skeletal anomalies, oral mucosal and dental anomalies, congenital cardiac defects, nail dysplasia and polydactyly of one or both limbs. It is caused by mutation of EVC1 and EVC2 genes located in a head-to-head configuration on chromosome 4p16, which has been identified as the causative. The EVC phenotype is variable and affects multiple organs. The presence of oral mucosal and dental alterations, like the presence of numerous frenulum, oligodontia, bellshaped anterior teeth, hypoplastic erupted teeth with high-caries index, will confirm the diagnosis of Ellis-van Creveld syndrome and hence its importance to dentists.

    Body compartments bound by fascia and limited by bony backgrounds are found in the extremities, buttocks, abdomen and thoracic cavity; conditions that cause intracompartmental swelling and hypertension can lead to ischemia and limb loss.Although compartment syndromes are described in all body regions from head to toe, the etiology, diagnosis, treatment, and prevention are best characterized for three key body regions: the first is extremity, the second is abdominal, and the third is thoracic compartment syndromes.Thoracic compartment syndrome usually occurs as a result of pathological accumulation of air, fluid or blood in the mediastinum and has traditionally been described in trauma.As the intracranial contents are confined within a rigid bony cage, any increase in volume within thiscompartment as a result of brain oedema or an expanding traumatic intracranial haematoma, leads to a reciprocal decrease in the volume of cerebrospinal fluid and intracranial venous blood volume.Limb compartment syndromes may present either in acute or chronic clinical forms.Intra-abdominal pressure can be measured by direct or indirect methods.While the direct methods are quite accurate, theyare impractical and not feasible for routine practice.Indirect measurement is done through inferior vena cava, gastric, rectal and urinary bladder.Indirect measurement through urinary bladder is the simplest and is considered the method of choice for intra-abdominal pressure measurement.The management of patients with intra-abdominal hypertension is based on four important principles: the first is related to the specific procedures aiming at lowering intra-abdominal pressure and the consequences of intra-abdominal hypertension and abdominal compartment syndrome; the second is for general support and medical management of the critically ill patient; while the third is surgical decompression and the fourth is optimization after surgical decompression.

    Tropical diabetic hand syndrome is a term used to describe diabetes complication of the hand affecting people in the tropics. It consists of localized cellulitis with variable swelling and ulceration of the hands, progressive, fulminant hand sepsis and gangrene in extreme cases. This syndrome is not well-recognized and is therefore less frequently reported. The authors describe three different female patients who were known diabetics of varying duration presenting with this syndrome at our tertiary health center and who were successfully managed by both the surgical and medical units. The need for early diagnosis and aggressive management is emphasized.

    A leptosomic body type is tall and thin with long hands. Marfanoid features may be familial in nature or pathological, as occurs in congenital contractual arachnodactyly (Beal's syndrome) and Shprintzen-Goldberg syndrome mimicking some of the changes of Marfan syndrome, although not accompanied by luxation of lens and dissecting aneurysm of aorta. In this article we collected eight patients who were consistent with the diagnosis of Marfan syndrome via phenotypic and genotypic characterization. Our patients manifested a constellation of variable presentations of musculo-skeletal abnormalities ranging from developmental dysplasia of the hip, protrusio acetabuli, leg length inequality, patellar instability, scoliosis, to early onset osteoarthritis. Each abnormality has been treated accordingly. This is the first paper which includes the diagnosis and the management of the associated musculo-skeletal abnormalities in patients with Marfan syndrome, stressing that patients with Marfan syndrome are exhibiting great variability in the natural history and the severity of musculo-skeletal abnormalities.

    Hemiconvulsion-hemiplegia-epilepsy syndrome is a rare consequence of a status epilepticus in the course of a febrile illness in children under the age of four years. Various degrees of hemiplegia and within a variable interval, subsequent epilepsia follows. Neuroimaging show unilateral cytotoxic oedema at the initial convulsive state, followed by severe chronic atrophy of the affected hemisphere. The aetiology remains unclear. Several mechanisms may contribute to this condition. To improve the outcome, further studies are needed and early diagnosis is essential.

    2017-01-01

    The purpose of this study is to examine whether water and air pollutants have a relationship with an increase in the genetic disorders Turner syndrome and Down syndrome, which are caused by congenital chromosomal abnormalities, and to generate a hypothesis about the genetic health effects of environmental pollutants. A panel regression based on random effect was conducted on Korea's metropolitan councils from 2012 to 2014. The dependent variable was the number of Turner syndrome and Down syndrome cases, and the main independent variables were those regarding the water and air pollution. Air pollutants did not have a significant impact on the number of Turner syndrome and Down syndrome cases; however, the increase in number of wastewater discharge companies did have a significant relationship with the number of cases. The more the number of wastewater discharge companies, the more the number Turner syndrome and Down syndrome cases were observed. Therefore, scientific investigation on water and air pollutants in relation with genetic health effects needs to be performed.

    2006-03-01

    Full Text Available Abstract The otodental syndrome also named otodental dysplasia, is characterised by a striking dental phenotype known as globodontia, associated with sensorineural high frequency hearing loss and eye coloboma. Globodontia occurs in both primary and permanent dentition, affecting canine and molar teeth (i.e. enlarged bulbous malformed posterior teeth with almost no discernable cusps or grooves. The condition appears to be inherited in an autosomal dominant mode, although sporadic cases have been reported. It is a rare disease, a few families have been described in the literature. In the British family, the locus for oculo-oto-dental syndrome was mapped to 20q13.1 within a 12-cM critical chromosomal region. Dental management is complex, interdisciplinary and will include regular follow up, scheduled teeth extraction and orthodontic treatment. Hearing checks and, if necessary, hearing aids are mandatory, as well as eye examination and ad hoc treatment if necessary.

    This is a systematic review of cases with Lemierre's syndrome (LS) in the past 5 years. LS is characterized by sepsis often evolving after a sore throat or tonsillitis and then complicated by various septic emboli and thrombosis of the internal jugular vein. Symptoms include sepsis, pain, and...... necrophorum. We found a total of 137 cases of LS, of which 47 were infected with F. necrophorum and others with Staphylococcus and Streptococcus. Complications of this rare but severe disease included osteomyelitis, meningitis, and acute respiratory distress syndrome. Mortality was extremely high in the pre......-antibiotic era but has diminished with the advent of antibiotics. This review showed a mortality rate of only 2% of which none of the cases involved fusobacteria. Duration of treatment varied; a 4-6-week course of carbapenem or piperacillin/tazobactam in combination with metronidazole was optimum. Other...

    Full Text Available Abstract "Dravet syndrome" (DS previously named severe myoclonic epilepsy of infancy (SMEI, or epilepsy with polymorphic seizures, is a rare disorder characterized by an early, severe, generalized, epileptic encephalopathy. DS is characterized by febrile and afebrile seizures beginning in the 1st year of life followed by different types of seizures (either focal or generalized, which are typically resistant to antiepileptic drugs. A developmental delay from the 2nd to 3rd year of life becomes evident, together with motor disturbances and personality disorders. Beside the classic syndrome, there are milder cases which have been called severe myoclonic epilepsy borderline (SMEB. DS is caused by a mutation in the neuronal sodium channel gene, SCN1A , that is also mutated in generalized epilepsy with FS+ (GEFS+.

    2017-03-01

    The antiphospholipid syndrome (APS) is defined by the development of venous and/or arterial thromboses, often multiple, and pregnancy morbidity (mainly, recurrent fetal losses), in the presence of antiphospholipid antibodies (aPL). Some estimates indicate that the incidence of the APS is around 5 new cases per 100,000 persons per year and the prevalence around 40-50 cases per 100,000 persons. The aPL are positive in approximately 13% of patients with stroke, 11% with myocardial infarction, 9.5% of patients with deep vein thrombosis and 6% of patients with pregnancy morbidity. Currently, there is consensus in treating APS patients with thrombosis with long-term oral anticoagulation and to prevent obstetric manifestations with the use of aspirin and heparin. This review summarizes the main knowledge on the clinical and therapeutic aspects of this syndrome. © 2017 Elsevier Ltd. All rights reserved.

    Five cases of a tumour in the quadrigeminal area have been described, 4 of which could be verified by autopsy. In 2 cases with a metastasis in the tegmentum of the mesencephalon, a Parinaud syndrome was present. In 2 other cases, however, with extensive destruction of the quadrigeminal plate and of the posterior commissure this syndrome was not present. In the 5th case, with a big vascular tumour of the pineal area, disturbances of eye movements and pupils were also lacking. From these observations we may conclude that (1) destruction of the quadrigeminal plate has no influence upon vertical eye movements. (2) destruction of the posterior commissure, in combination with the quadrigeminal plate, is not always followed by disturbances of vertical eye movements. In man it is still not clear which structures are responsible for the performance of vertical eye movements.

    Full Text Available Apert syndrome (acrocephalosyndactyly is a rare developmental malformation characterized by craniosynostosis, mid-face hypoplasia, symmetrical syndactyly of hands and feet. The prodromal characteristics for the typical cranio-facial appearance are early craniosynostosis of the coronal suture, cranial base and agenesis of the sagittal suture. The purpose of this paper is to report a case of Apert syndrome with emphasis on craniofacial and oral features in an eighteen-month-old male child. The patient presented with several craniofacial deformities, including brachycephaly, midface hypoplasia, flat face, hypertelorism, ocular proptosis, downslanting palpebral fissures. Syndactylies with osseous fusion of the hands and feet were also observed. Intraoral findings included delayed eruption of teeth, high arched palate with pseudo cleft in the posterior one third.

    1994-03-01

    Paraneoplastic syndromes (PNS) comprise a diverse group of disorders that are associated with cancer but unrelated to the size, location, metastases, or physiologic activities of the mature tissue of origin. They are remote effects of tumors that may appear as signs, symptoms, or syndromes which can mimic other disease conditions encountered in veterinary medicine. Recognition of PNS is valuable for several reasons: the observed abnormalities may represent tumor cell markers and facilitate early diagnosis of the tumor; they may allow assessment of premalignant states; they may aid in the search metastases; they may help quantify and monitor response to therapy; and, they may provide insight into the study of malignant transformation and oncogene expression. This review will concentrate on the pathophysiology, diagnosis, and treatment of some of the common PNS encountered in veterinary medicine.

    Hepatorenal syndrome (HRS) is a "functional" and reversible form of renal failure that occurs in patients with advanced chronic liver disease. The distinctive hallmark feature of HRS is the intense renal vasoconstriction caused by interactions between systemic and portal hemodynamics. This results in activation of vasoconstrictors and suppression of vasodilators in the renal circulation. Epidemiology, pathophysiology, as well as current and emerging therapies of HRS are discussed in this review.

    The Fibromialgia Syndrome (FS) is a common clinical entity which may produce symtoms and signs related to multiple fields of Medicine. Typical clinical characteristics of FS include extensive pain, presence of sensitive points during exploration, morning stiffness, asthenia and non-refresing sleep. Frequently, associated rheumatologic diseases are observed, as rheumatoid arthritis, osteoarthrosis and vertebral disorders. In FS, complementary tests are usually normal. The most widely accepted hypothesis suggests that this is a disorder affecting modulation of pain sensitivity.

    Full Text Available Antiphospholipid syndrome (APS is an autoimmune disease with recurrent thromboses and pregnancy complications (90% are female patients that can be primary and secondary (with concomitant autoimmune disease. Antiphospholipid antibodies are prothrombotic but also act directly with brain tissue. One clinical and one laboratory criterion is necessary for the diagnosis of APS. Positive serological tests have to be confirmed after at least 12 weeks. Clinical picture consists of thromboses in many organs and spontaneous miscarriages, sometimes thrombocytopaenia and haemolytic anaemia, but neurological cases are the most frequent: headaches, stroke, encephalopathy, seizures, visual disturbances, Sneddon syndrome, dementia, vertigo, chorea, balism, transitory global amnesia, psychosis, transversal myelopathy and Guillain-Barre syndrome. About 50% of strokes below 50 years of age are caused by APS. The first line of therapy in stroke is anticoagulation: intravenous heparin or low-weight heparins. In chronic treatment, oral anticoagulation and antiplatelet therapy are used, warfarin and aspirin, mostly for life. In resistant cases, corticosteroids, intravenous immunoglobulins and plasmapheresis are necessary. Prognosis is good in most patients but some are treatment-resistant with recurrent thrombotic events and eventually death.

Patients usually present with chronic recurrent rhinosinusitis, otitis media, pneumonia, and bronchiectasis caused by pseudomonal infection. Situs inversus can be seen in about 50% of cases. Diagnosis can be made by tests to prove impaired cilia function, biopsy, and genetic studies. Treatment is supportive. In severe cases, the prognosis can be fatal if bilateral lung transplantation is delayed. We present a case of a 66-year-old woman with chronic recurrent upper respiratory infections, pseudomonal pneumonia, and chronic bronchiectasis who presented with acute respiratory failure. She was diagnosed with Kartagener syndrome based on her clinical presentation and genetic studies.

    2012-09-01

    Full Text Available The first detailed cases of crush syndrome were described in 1941 in London after victims trapped beneath bombed buildings presented with swollen limbs, hypovolemic shock, dark urine, renal failure, and ultimately perished. The majority of the data and studies on this topic still draw from large databases of earthquake victims. However, in Africa, a continent with little seismic activity, the majority of crush syndrome cases are instead victims of severe beatings rather than earthquake casualties, and clinical suspicion by emergency personnel must be high in this patient group presenting with oliguria or pigmenturia. Damaged skeletal muscle fibres and cell membranes lead to an inflammatory cascade resulting in fluid sequestration in the injured extremity, hypotension, hyperkalemia and hypocalcemia and their complications, and renal injury from multiple sources. Elevations in the serum creatinine, creatine kinase (CK, and potassium levels are frequent findings in these patients, and can help guide critical steps in management. Fluid resuscitation should begin prior to extrication of trapped victims or as early as possible, as this basic intervention has been shown to in large part prevent progression of renal injury to requiring haemodialysis. Alkalinization of the urine and use of mannitol for forced diuresis are recommended therapies under specific circumstances and are supported by studies done in animal models, but have not been shown to change clinical outcomes in human crush victims. In the past 70 years the crush syndrome and its management have been studied more thoroughly, however clinical practice guidelines continue to evolve.

    There are numerous reports of multi-system genetic disorders with obesity. Many have a characteristic presentation and several, an overlapping phenotype indicating the likelihood of a shared common underlying mechanism or pathway. By understanding the genetic causes and functional perturbations of such syndromes we stand to gain tremendous insight into obesogenic pathways. In this review we focus particularly on Bardet-Biedl syndrome, whose molecular genetics and cell biology has been elucidated recently, and Prader-Willi syndrome, the commonest obesity syndrome due to loss of imprinted genes on 15q11-13. We also discuss highlights of other genetic obesity syndromes including Alstrom syndrome, Cohen syndrome, Albright's hereditary osteodystrophy (pseudohypoparathyroidism), Carpenter syndrome, MOMO syndrome, Rubinstein-Taybi syndrome, cases with deletions of 6q16, 1p36, 2q37 and 9q34, maternal uniparental disomy of chromosome 14, fragile X syndrome and Börjeson-Forssman-Lehman syndrome.

    The distribution of a syndrome in space and time may suggest clues to its etiology. The cause of Kawasaki syndrome, a systemic vasculitis of infants and children, is unknown, but an infectious etiology is suspected. Seasonality and clustering of Kawasaki syndrome cases were studied in Japanese children with Kawasaki syndrome reported in nationwide surveys in Japan. Excluding the years that contained the 3 major nationwide epidemics, 84,829 cases during a 14-year period (1987-2000) were analyzed. To assess seasonality, we calculated mean monthly incidence during the study period for eastern and western Japan and for each of the 47 prefectures. To assess clustering, we compared the number of cases per day (daily incidence) with a simulated distribution (Monte Carlo analysis). Marked spatial and temporal patterns were noted in both the seasonality and deviations from the average number of Kawasaki syndrome cases in Japan. Seasonality was bimodal with peaks in January and June/July and a nadir in October. This pattern was consistent throughout Japan and during the entire 14-year period. Some years produced very high or low numbers of cases, but the overall variability was consistent throughout the entire country. Temporal clustering of Kawasaki syndrome cases was detected with nationwide outbreaks. Kawasaki syndrome has a pronounced seasonality in Japan that is consistent throughout the length of the Japanese archipelago. Temporal clustering of cases combined with marked seasonality suggests an environmental trigger for this clinical syndrome.

    Traditionally, differentiation of syndromes of Traditional Chinese Medicine (TCM) mainly depends on the information obtained from four diagnosis methods. Now many physicochemical parameters are available in clinic. There exists great correlation between TCM syndromes and physicochemical parameters.The objective of the paper is to analyze the correlation between TCM syndromes and physicochemical parameters quantitatively. Correlation analysis has been widely studied and many analysis methods have been developed. Mutual information based on entropy can measure arbitrary dependence between variables. It has been applied to many kinds of fields, especially to pattern recognition. But most works are restricted to discrete variables and little work has been done to study the relation between discrete and continuous variables. A novel algorithm is proposed to calculate the mutual information between discrete and continuous variables. It is used to analyze the correlation between TCM syndromes and physicochemical parameters.

    We report three cases of Raynaud's syndrome with digital ischaemic ulceration, in association with carpal tunnel syndrome. In all cases, the aetiology of the Raynaud's syndrome was probably unrelated to the nerve compression. However, symptoms were worse on the side of the median nerve lesion in two patients and worse on the side with the most severe nerve dysfunction in the third; symptoms were relieved by carpal tunnel decompression in two patients. We suggest that carpal tunnel syndrome ma...

    Hepatorenal syndrome (HRS) is defined as a functional renal failure in patients with liver disease with portal hypertension and it constitutes the climax of systemic circulatory changes associated with portal hypertension.This term refers to a precisely specified syndrome featuring in particular morphologically intact kidneys,where regulatory mechanisms have minimised glomerular filtration and maximised tubular resorption and urine concentration,which ultimately results in uraemia.The syndrome occurs almost exclusively in patients with ascites.Type 1 HRS develops as a consequence of a severe reduction of effective circulating volume due to both an extreme splanchnic arterial vasodilatation and a reduction of cardiac output.Type 2 HRS is characterised by a stable or slowly progressive renal failure so that its main clinical consequence is not acute renal failure,but refractory ascites,and its impact on prognosis is less negative.Liver transplantation is the most appropriate therapeutic method,nevertheless,only a few patients can receive it.The most suitable "bridge treatments" or treatment for patients ineligible for a liver transplant include terlipressin plus albumin.Terlipressin is at an initial dose of 0.5-1 mg every 4 h by intravenous bolus to 3 mg every 4 h in cases when there is no response.Renal function recovery can be achieved in less than 50% of patients and a considerable decrease in renal function may reoccur even in patients who have been responding to therapy over the short term.Transjugular intrahepatic portosystemic shunt plays only a marginal role in the treatment of HRS.

    2016-01-01

    A 74-year-old gentleman was admitted to the regional neurosciences center with encephalopathy, myokymia, and dysautonomia. Chest imaging had previously identified an incidental mass in the anterior mediastinum, consistent with a primary thymic tumor. Antivoltage-gated potassium channel (anti-VGKC) antibodies were positive (titer 1273 pmol/L) and he was hypokalemic. Electromyogram and nerve conduction studies were in keeping with peripheral nerve hyperexcitability syndrome, and an electroencephalogram was consistent with encephalopathy. A diagnosis of Morvan syndrome was made, for which he was initially treated with high-dose steroids, followed by a 5-day course of intravenous immunoglobulin (IVIG) therapy. He also underwent thymectomy, followed by a postexcision flare of his symptoms requiring intensive care management. Further steroids, plasmapheresis, and IVIG achieved stabilization of his clinical condition, enabling transfer for inpatient neurorehabilitation. He was commenced on azathioprine and a prolonged oral steroid taper. A subsequent presumed incipient relapse responded well to further IVIG treatment. This case report documents a thymoma-associated presentation of anti-VGKC-positive Morvan syndrome supplemented by patient and carer narrative and video, both of which provide valuable further insights into this rare disorder. There are a limited number of publications surrounding this rare condition available in the English literature. This, combined with the heterogenous presentation, association with underlying malignancy, response to treatment, and prognosis, provides a diagnostic challenge. However, the association with anti-VGKC antibody-associated complexes and 2 recent case series have provided some scope for both accurate diagnosis and management. PMID:26740856

    This article reports on 14 cases of a trichorhinophalangeal syndrome in five successive generations. Besides the well-known characteristics of the TRPS the following symptoms observed in this family are new: Teething was considerably delayed, intelligence was reduced, and there were skin manifestations resembling eczema. Besides, struma colli and colitis ulcerosa were also observed. Subsequent observations have to clarify whether these symptoms are a facultative part of the TRPS pattern. The constant appearance of carriers of these characteristics during five generation points to dominant heredity.

Then evaluation of fetal status and planning delivery method and time if maternal status remains unstable. If prognosis seems favorable without urgent delivery and fetus can benefit from it, a course of betamethasone can be given to fetuses between 24 and 34 weeks of gestational age. The only and definite treatment of HELLP syndrome is delivering the baby. Suggested benefits of steroid therapy and other experimental treatments are still to be proven effective by large randomized controlled trials.

    Jacobsen syndrome is a MCA/MR contiguous gene syndrome caused by partial deletion of the long arm of chromosome 11. To date, over 200 cases have been reported. The prevalence has been estimated at 1/100,000 births, with a female/male ratio 2:1. The most common clinical features include pre- and postnatal physical growth retardation, psychomotor retardation, and characteristic facial dysmorphism (skull deformities, hypertelorism, ptosis, coloboma, downslanting palpebral fissures, epicanthal folds, broad nasal bridge, short nose, v-shaped mouth, small ears, low set posteriorly rotated ears). Abnormal platelet function, thrombocytopenia or pancytopenia are usually present at birth. Patients commonly have malformations of the heart, kidney, gastrointestinal tract, genitalia, central nervous system and skeleton. Ocular, hearing, immunological and hormonal problems may be also present. The deletion size ranges from approximately 7 to 20 Mb, with the proximal breakpoint within or telomeric to subband 11q23.3 and the deletion extending usually to the telomere. The deletion is de novo in 85% of reported cases, and in 15% of cases it results from an unbalanced segregation of a familial balanced translocation or from other chromosome rearrangements. In a minority of cases the breakpoint is at the FRA11B fragile site. Diagnosis is based on clinical findings (intellectual deficit, facial dysmorphic features and thrombocytopenia) and confirmed by cytogenetics analysis. Differential diagnoses include Turner and Noonan syndromes, and acquired thrombocytopenia due to sepsis. Prenatal diagnosis of 11q deletion is possible by amniocentesis or chorionic villus sampling and cytogenetic analysis. Management is multi-disciplinary and requires evaluation by general pediatrician, pediatric cardiologist, neurologist, ophthalmologist. Auditory tests, blood tests, endocrine and immunological assessment and follow-up should be offered to all patients. Cardiac malformations can be very severe

    The features of the Chilaiditi Syndrome are described, together with the historial background, and a brief review of the literature on the condition is given. The prevalence in our geriatric population was found to be 1% and the 13 cases seen over 22 months are reported briefly. The prevalence increases with age and may be related to the consumption of drugs by the elderly; although in the majority it is asymptomatic, it may, particularly when associated with gastrointestinal symptoms, lead to unnecessary laparotomy. In the geriatric patient, interposition of the bowel should be considered in the differential diagnosis of air under the right hemidiaphragm.

    Refeeding syndrome (RFS) is the result of aggressive enteral or parenteral feeding in a malnourished patient, with hypophosphatemia being the hallmark of this phenomenon. Other metabolic abnormalities, such as hypokalemia and hypomagnesemia, may also occur, along with sodium and fluid retention. The metabolic changes that occur in RFS can be severe enough to cause cardiorespiratory failure and death. This article reviews the pathophysiology, the clinical manifestations, and the management of RFS. The key to prevention is identifying patients at risk and being aware of the potential complications involved in rapidly reintroducing feeds to a malnourished patient.

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women and the leading cause of anovulatory infertility. The prevalence of the syndrome ranges between 6 to 15% based on broader Rotterdam diagnostic criteria verses strict NIH diagnostic criteria.1 The condition is characterized by a combination of ovulatory dysfunction, hyperandrogenism and the presence of polycystic ovaries. PCOS has been associated with multiple metabolic alterations and consequences including impaired glucose tolerance, insulin resistance, hyperinsulinemia, type II diabetes, dyslipidemia, metabolic syndrome, obesity and subclinical cardiovascular disease. It remains unclear however if these associations lead to an increased risk of clinically significant long-term cardiovascular disease. Large prospective studies to date have not detected significant differences in overall cardiovascular morbidity and mortality in PCOS. The phenotypical variability in PCOS has made researching each of these associations challenging as different aspects of the syndrome may be contributing, opposing or confounding factors. The ability to detect significant differences in long-term cardiovascular outcomes may also be due to the variable nature of the syndrome. In this review, we attempt to describe a summary of the current literature concerning the metabolic alterations and cardiovascular consequences of polycystic ovary syndrome.

    The prognosis following appropriate antibiotic treatment of early or late Lyme disease is favorable but can be complicated by persistent symptoms of unknown cause termed posttreatment Lyme disease syndrome (PTLDS), characterized by fatigue, musculoskeletal pain, and cognitive complaints that persist for 6 months or longer after completion of antibiotic therapy. Risk factors include delayed diagnosis, increased severity of symptoms, and presence of neurologic symptoms at time of initial treatment. Two-tier serologic testing is neither sensitive nor specific for diagnosis of PTLDS because of variability in convalescent serologic responses after treatment of early Lyme disease. Optimal treatment of PTLDS awaits more precise understanding of the pathophysiologic mechanisms involved in this illness and future treatment trials. Copyright © 2015 Elsevier Inc.

    2017-01-01

    Full Text Available Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

The prevalence of MWS is currently unknown, but 171 patients have been reported so far. It seems probable that MWS is under-diagnosed, particularly in patients without HSCR. MWS is caused by heterozygous mutations or deletions in the Zinc finger E-box-binding homeobox 2 gene, ZEB2, previously called ZFHX1B (SIP1. To date, over 100 deletions/mutations have been reported in patients with a typical phenotype; they are frequently whole gene deletions or truncating mutations, suggesting that haploinsufficiency is the main pathological mechanism. Studies of genotype-phenotype analysis show that facial gestalt and delayed psychomotor development are constant clinical features, while the frequent and severe congenital malformations are variable. In a small number of patients, unusual mutations can lead to an atypical phenotype. The facial phenotype is particularly important for the initial clinical diagnosis and provides the hallmark warranting ZEB2 mutational analysis, even in the absence of HSCR. The majority of MWS cases reported so far were sporadic, therefore the recurrence risk is low. Nevertheless, rare cases of sibling recurrence have been observed.

    Full Text Available Abstract Lowe syndrome (the oculocerebrorenal syndrome of Lowe, OCRL is a multisystem disorder characterised by anomalies affecting the eye, the nervous system and the kidney. It is a uncommon, panethnic, X-linked disease, with estimated prevalence in the general population of approximately 1 in 500,000. Bilateral cataract and severe hypotonia are present at birth. In the subsequent weeks or months, a proximal renal tubulopathy (Fanconi-type becomes evident and the ocular picture may be complicated by glaucoma and cheloids. Psychomotor retardation is evident in childhood, while behavioural problems prevail and renal complications arise in adolescence. The mutation of the gene OCRL1 localized at Xq26.1, coding for the enzyme phosphatidylinositol (4,5 bisphosphate 5 phosphatase, PtdIns (4,5P2, in the trans-Golgi network is responsible for the disease. Both enzymatic and molecular testing are available for confirmation of the diagnosis and for prenatal detection of the disease. The treatment includes: cataract extraction, glaucoma control, physical and speech therapy, use of drugs to address behavioural problems, and correction of the tubular acidosis and the bone disease with the use of bicarbonate, phosphate, potassium and water. Life span rarely exceeds 40 years.

    2013-01-01

    Full Text Available Cardiovascular disease is the leading cause of death in patients with chronic kidney disease.  Heart failure may lead to acute kidney injury and vice versa. Chronic kidney disease may affect the clinical outcomes in patients with cardiovascular disorders. Renal impairment with any degree of albuminuria has been increasingly recognized as an independent risk factor for cardiovascular events and heart failure hospitalizations, while chronic heart failure may cause chronic kidney disease. The bidirectional nature of these disorders contributes to the complexity and the composite definitions of cardiorenal syndromes. However, the most important clinical trials in heart failure tend to exclude patients with significant renal dysfunction. The mechanisms whereby renal insufficiency worsens the outcome in heart failure are not known, and several pathways could contribute to the ‘‘vicious heart/kidney circle.’’ Traditionally, renal impairment has been attributed to the renal hypoperfusion due to reduced cardiac output and decreased systemic pressure. The hypovolemia leads to sympathetic activity, increased renin-angiotensin aldosterone pathway, and arginine-vasopressin release. These mechanisms cause fluid and sodium retention, peripheral vasoconstriction, and volume overload. Therapy to improve renal dysfunction, reduce neurohormonal activation and ameliorate renal blood flow could lead to a reduction in mortality and hospitalization in patients with cardiorenal syndrome.

    2006-12-01

    Full Text Available Abstract KBG syndrome is a rare condition characterised by a typical facial dysmorphism, macrodontia of the upper central incisors, skeletal (mainly costovertebral anomalies and developmental delay. To date, KBG syndrome has been reported in 45 patients. Clinical features observed in more than half of patients that may support the diagnosis are short stature, electroencephalogram (EEG anomalies (with or without seizures and abnormal hair implantation. Cutaneous syndactyly, webbed short neck, cryptorchidism, hearing loss, palatal defects, strabismus and congenital heart defects are less common findings. Autosomal dominant transmission has been observed in some families, and it is predominantly the mother, often showing a milder clinical picture, that transmits the disease. The diagnosis is currently based solely on clinical findings as the aetiology is unknown. The final diagnosis is generally achieved after the eruption of upper permanent central incisors at 7–8 years of age when the management of possible congenital anomalies should have been already planned. A full developmental assessment should be done at diagnosis and, if delays are noted, an infant stimulation program should be initiated. Subsequent management and follow-up should include an EEG, complete orthodontic evaluation, skeletal investigation with particular regard to spine curvatures and limb asymmetry, hearing testing and ophthalmologic assessment.

    2013-04-01

    Sheehan's syndrome (SS) is characterized by various degrees of hypopituitarism, and develops as a result of ischemic pituitary necrosis due to severe postpartum hemorrhage. Increased pituitary volume, small sella size, disseminated intravascular coagulation and autoimmunity are the proposed factors in the pathogenesis of SS. Hormonal insufficiencies, ranging from single pituitary hormone insufficiency to total hypopituitarism, are observed in patients. The first most important issue in the diagnosis is being aware of the syndrome. Lack of lactation and failure of menstrual resumption after delivery that complicated with severe hemorrhage are the most important clues in diagnosing SS. The most frequent endocrine disorders are the deficiencies of growth hormone and prolactin. In patients with typical obstetric history, prolactin response to TRH seems to be the most sensitive screening test in diagnosing SS. Other than typical pituitary deficiency, symptoms such as anemia, pancytopenia, osteoporosis, impairment in cognitive functions and impairment in the quality of life are also present in these patients. Treatment of SS is based on the appropriate replacement of deficient hormones. Growth hormone replacement has been found to have positive effects; however, risk to benefit ratio, side effects and cost of the treatment should be taken into account.

    Full Text Available Nevoid basal cell carcinoma syndrome (Gorlin syndrome is an autosomal dominant inherited condition that exhibits high penetrance and variable expressivity. The syndrome is caused by mutations in patched (PTCH, a tumor suppressor gene that has been mapped to chromosome 9q22.3-q31. Gorlin-goltz syndrome (GGS is characterised by the presence of multiple odontogenic keratocysts in the jaws, basal cell carcinomas, palmar and plantar pits and intracranial calcifications. Here, we present a case of familial GGS, characterised by multiple odontogenic keratocysts, broad nasal ridge, hypertelorism, enlarged head circumference and dermoid cysts.

    Sheehan's syndrome occurs as a result of ischemic pituitary necrosis secondary to severe postpartum bleeding. It is one of the most common causes of hypopituitarism, characterized by variable clinical presentation. Acute kidney injury occurs rarely in Sheehan's syndrome and most of the cases have been found to be precipitated by rhabdomyolysis. We here present a case of Sheehan's syndrome with acute kidney injury where theprecipitating cause was chronic hypocortisolemia. We believe this is the first reported case of Sheehan's syndrome in which acute kidney injury was precipitated by adrenal insufficiency.

    Good's syndrome is a relatively rare immunodeficiency condition that presents in the fourth or fifth decade of life and is defined by hypogammaglobulinemia in the setting of a thymoma. The humoral defect may be severe enough to cause an absence in B cells, with a consequent recurrence of sinopulmonary disease, chronic non-infectious diarrhea and opportunistic infections. The prognosis in patients with Good's syndrome appears to be worse than in those with X-linked agammaglobulinemia (XLA) and common variable immune deficiency (CVID). There have only been three cases of Good's syndrome associated with mycobacterium, and only one case with a cavitary lesion in the lungs. We present here a unique case of Good's syndrome with a non-mycobacterial cavitary lesion.

    Hypogammaglobulinemia or agammaglobulinemia are major features of specific syndromes, including X-linked agammaglobulinemia and common variable immunodeficiency. However, the combination of hypogammaglobulinemia with specific dysmorphic features is less common, with only a few reported cases. One such report was a sporadic case of humoral immunodeficiency, facial dysmorphism, and limb anomalies in a young girl, later referred to as Hoffman syndrome. We report on a 7-year-old girl with almost complete loss of B cells, facial dysmorphism, and malformation of the limbs and genitalia, whose mother shows similar dysmorphic features with an attenuated version of the B-cell deficiency. We believe that all three cases described above represent the same condition. The features of the three affected individuals with Hoffman syndrome are reviewed. Further investigations in this recently recognized B-cell immunodeficiency syndrome are warranted.

    Full Text Available The Kleine–Levin Syndrome is a differential diagnosis for patients with diurnal excessive sleepiness and a suspicion of narcolepsy. It is characterized by paroxysmal attacks of diurnal excessive sleepiness, associated with one or more symptoms of hyperphagia, hypersexuality, coprolalia and copropraxia. During crisis intervals, there are no symptoms. This pathology predominantly manifests itself in teenagers, being more frequent among males. The course of this disease is unpredictable, with variable duration and frequency. The most accepted physiopathology is that of a hypothalamic dysfunction, although and recently, there has appeared a hypothesis of a post-infectious autoimmune disorder. These patients show an elevated body mass index, which can predispose to association with comorbidities such as the sleep obstructive apnea syndrome. Treatment involves medications with different effects, but there is no specific and effective therapy. Our article shows a classic case of Kleine–Levin Syndrome associated with sleep obstructive apnea syndrome, a rare association in the literature.

    Dreissen, Yasmine E M; Tijssen, Marina A J

    2012-12-01

    Startle syndromes are paroxysmal and show stimulus sensitivity, placing them in the differential diagnosis of epileptic seizures. Startle syndromes form a heterogeneous group of disorders with three categories: hyperekplexia (HPX), stimulus-induced disorders, and neuropsychiatric syndromes. HPX is characterized by an exaggerated motor startle reflex combined with stiffness and is caused by mutations in different parts of the inhibitory glycine receptor, leading to brainstem pathology. The preserved consciousness distinguishes it from epileptic seizures. Clonazepam is the first-choice therapy. The stimulus-induced disorders cover a broad range of epileptic and nonepileptic disorders, and distinguishing the two can be difficult. Additional information from electroencephalography (EEG) and video registration can help. Many stimulus-induced disorders now have an identified gene defect. Antiepileptic drugs, including benzodiazepines, are frequently mentioned as the best treatment option. Neuropsychiatric syndromes are on the borderland of neurology and psychiatry, and their etiology is poorly understood. These syndromes include startle-induced tics, culture-specific disorders such as Latah, and functional startle syndromes. The electromyography (EMG) startle reflex in these syndromes is characterized by variable recruitment patterns and the presence of a second "orienting" response. Treatment options are limited, but urgently required. In the clinical setting, the patient's history and a (home) video recording together with genetic and electrophysiologic testing help to classify these challenging disorders.

    The status of night-to-night variability for periodic limb movements in sleep (PLMS) has not been clarified. With this in mind, we investigated the validity of PLMS measurement by actigraphy with the PAM-RL device in Japanese patients with suspected restless legs syndrome (RLS) or periodic limb movement disorder (PLMD) and the night-to-night variability of PLMS among the subjects. Forty-one subjects (mean age, 52.1±16.1 years) underwent polysomnography (PSG) and PAM-RL measurement simultaneously. Thereafter, subjects used the PAM-RL at home on four more consecutive nights. The correlation between PLMS index on PSG (PLMSI-PSG) and PLM index on PAM-RL (PLMI-PAM) was 0.781 (P<.001). When the PLMSI cutoff value on PSG was set at 15 episodes per hour, the cutoff value for predicting this PLMSI level was 16.0 episodes per hour. When the condition was set to the level in which the mean interclass correlation coefficient reached ≥0.9, the number of required nights for repeated measurements was 26 nights for subjects with PLMI of <15 episodes per hour and three nights for those with PLMI ≥15 episodes per hour on PAM-RL. PAM-RL is thought to be valuable for assessing PLMS even in Japanese subjects. Recording of PAM-RL for three or more consecutive nights may be required to ensure the screening reliability of a patient with suspected pathologically frequent PLMS. Copyright © 2013 Elsevier B.V.

    Mortada, Rami; Williams, Tracy

    2015-08-01

    Polycystic ovary syndrome (PCOS) is a heterogeneous condition characterized by androgen excess, ovulatory dysfunction, and polycystic ovaries. It is the most common endocrinopathy among women of reproductive age, affecting between 6.5% and 8% of women, and is the most common cause of infertility. Insulin resistance is almost always present in women with PCOS, regardless of weight, and they often develop diabetes and metabolic syndrome. The Rotterdam criteria are widely used for diagnosis. These criteria require that patients have at least two of the following conditions: hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. The diagnosis of PCOS also requires exclusion of other potential etiologies of hyperandrogenism and ovulatory dysfunction. The approach to PCOS management differs according to the presenting symptoms and treatment goals, particularly the patient's desire for pregnancy. Weight loss through dietary modifications and exercise is recommended for patients with PCOS who are overweight. Oral contraceptives are the first-line treatment for regulating menstrual cycles and reducing manifestations of hyperandrogenism, such as acne and hirsutism. Clomiphene is the first-line drug for management of anovulatory infertility. Metformin is recommended for metabolic abnormalities such as prediabetes, and a statin should be prescribed for cardioprotection if the patient meets standard criteria for statin therapy.

    2017-07-01

    Full Text Available Trichorhinophalangeal syndrome (TRPS is the collective name of three rare congenital conditions characterised by craniofacial and skeletal abnormalities. The three known types of TRPS have different modalities of genetic transmission: namely, TRPS I and III are inherited as an autosomal dominant disease, while the cases of TRPS II are essentially sporadic.The diagnosis of the different types of TRPS is based on clinical and radiological findings, eventually integrated by genetic analysis, particularly useful in some cases with the non-classical clinical presentation. Alopecia and structural abnormalities of the nose and the hands should be considered as clinical hallmarks, whereas endocrine disorders, renal alterations, ureteral reflux, heart pathology and bone dysplasia have been documented, in the setting of a multisystem involvement.

  1. Hypereosinophilic syndromes

    Full Text Available Background: The last few years have seen a complete change in the etiopathogenetic features, classification and therapeutic approach of the hypereosinophilic syndrome (HES, a multiorgan targeted blood disease. The discovery of a genetic mutation and the occurrence of a new fusion gene, named FIP1L1-PDGFRA (FIP gene, in some patients allowed the identification of a new myeloproliferative disorder, M-HES: thereafter, the pivotal therapeutic role of the tyrosine kinase inhibitors, particularly, imatinib mesylate, was clearly detected. In the same period a new pathogenetic mechanism has been detected: some authors described the presence of a CD3-CD4 +Tcell clone correlating with the overproduction of IL5, a potent eosinophilic cell line stimulating cytokine. As a consequence an international consensus committee proposed a new classification for these syndromes, in accordance with these new pathogenetic features. The disease is characterized by an extensive tissue and organ damage due to an eosinophilic cell infiltration and leading to the release of toxic cytokines and subsequent organ dysfunction. The heart, lungs, gastrointestinal apparatus, skin and central nervous system are affected. Moreover the released cytokines can induce a thrombophilic status and thromboembolic events can occur throughout the body. Aim of the study: We describe the diagnostic procedures that are necessary in order to obtain a correct diagnosis and classification of the disease and to evaluate the presence of an organ and tissue damage. In particular, bone marrow biopsy and cytogenetic examination of blood and marrow are necessary for detecting M-HES cases that are positive for the FIP gene. In these patients, imatinib mesylate has a leading role for obtaining complete remission of the disease in a high percentage of cases. We also examine the therapeutic options for the other forms of the disease: prednisone, interferon, hydroxiurea are effective therapeutic tools in

    The present study was conducted to assess the relationships between metabolic syndrome and metabolic syndrome score (MSS) and beta cell function by gender in Korean populations with obesity. This study included 1,686 adults aged 20 or older using the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data, which represent national data in Korea. The key study results were as follows: First, in men, after adjusting for related variables (including body mass index), metabolic syndrome (p=0.005) and MSS (p=0.018) were inversely associated with the homeostatic model assessment of beta cell function (HOMA-B) values. Second, in women, after adjusting for related variables, metabolic syndrome (p=0.616) and MSS (p=0.929) were not associated with HOMA-B levels. In conclusion, metabolic syndrome and MSS were inversely associated with beta cell function in Korean men with obesity, but not in Korean women with obesity.

    Between 1981 and 1987 5434 patients were studied by ERCP in Allgemeines Krankenhaus Hamburg-Barmbeck. 26 (i.e. 0.43%) suffered from Mirizze syndrome with the triad of cholelithiasis, cholecystitis and obstructive biliary disease. They were classified in four different types according to the variable localisation and origin of the biliary obstruction. 16 patients corresponded to the classical type (I and II) with compression, penetration, and obturation by the concrement, five patients matched borderline with infiltration (III) and five patients were classified as variants of this syndrome. A mild elevation of serum bilirubine and alkaline phosphatase indicated more likely the benign etiology of type I to III, however, a marked elevation of alkaline phosphatase in the variants suggested more likely a malignant underlying disease. The diagnosis was ascertained in all cases by ERC and sonography preoperatively and was verified by laparotomy (n = 18) and follow-up (n = 6).

    ObjectiveTo study the time-dependent heart rate (HR) variability in the head-up tilt test (HUTT) in children with postural orthostatic tachycardia syndrome (POTS) and to explore the HR diagnostic criteria for POTS in children.MethodsA retrospective analysis was performed on the clinical data of 105 children diagnosed with POTS with HR ≥120 beats per minute (bpm) within the ifrst 10 minutes of HUTT between January 2007 and December 2014. Their HR variability within the first 10 minutes of HUTT was analyzed.ResultsThe HR of children with POTS increased gradually from the supine position to a 60° head-up tilt position, and the increase in HR was 24±12 bpm at the beginning of HUTT, 30±14 bpm at 3 minutes of HUTT, 32±13 bpm at 5 minutes of HUTT, and 38±12 bpm at 10 minutes of HUTT. The average maximal HR increase within the ifrst 10 minutes of HUTT was 43±10 bpm.ConclusionsIn children with POTS, the HR variability gradually increases with time, and therefore, it is suggested that HR increase ≥40 bpm is more suitable for diagnosis of POTS in children.%目的:分析体位性心动过速综合征(POTS)儿童在直立倾斜试验(HUTT)过程中时间依赖性的心率变化,探讨儿童POTS的心率诊断标准。方法回顾性研究2007年1月至2014年12月的HUTT 10 min内最大心率≥120次/min诊断为POTS儿童105例,分析其在HUTT 10 min内心率的变化。结果POTS儿童由平卧位变为倾斜60°体位时心率逐渐增加,在HUTT即刻心率增加24±12次/min,HUTT 后3 min心率增加30±14次/min,5 min时增加32±13次/min,10 min时增加38±12次/min。10 min内HUTT最大心率增加值平均为43±10次/min。结论POTS儿童HUTT 10 min内心率变化随时间延长而增加,建议儿童POTS诊断标准中心率增加≥40次/min较为适合。

    2011-06-01

    A high rate of Attention Deficit/Hyperactivity Disorder (ADHD)-like characteristics has been reported in a wide variety of disorders including syndromes with known genetic causes. In this article, we review the genetic and the neurobiological links between ADHD symptoms and some genetic syndromes such as: Fragile X Syndrome, Neurofibromatosis 1, DiGeorge Syndrome, Tuberous Sclerosis Complex, Turner Syndrome, Williams Syndrome and Klinefelter Syndrome. Although each syndrome may arise from different genetic abnormalities with multiple molecular functions, the effects of these abnormalities may give rise to common effects downstream in the biological pathways or neural circuits, resulting in the presentation of ADHD symptoms. Early diagnosis of ADHD allows for earlier treatment, and has the potential for a better outcome in children with genetic syndromes.

    Full Text Available Abstract Ellis-van Creveld syndrome (EVC is a chondral and ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation, and ectodermal and heart defects. It is a rare disease with approximately 150 cases reported worldwide. The exact prevalence is unknown, but the syndrome seems more common among the Amish community. Prenatal abnormalities (that may be detected by ultrasound examination include narrow thorax, shortening of long bones, hexadactyly and cardiac defects. After birth, cardinal features are short stature, short ribs, polydactyly, and dysplastic fingernails and teeth. Heart defects, especially abnormalities of atrial septation, occur in about 60% of cases. Cognitive and motor development is normal. This rare condition is inherited as an autosomal recessive trait with variable expression. Mutations of the EVC1 and EVC2 genes, located in a head to head configuration on chromosome 4p16, have been identified as causative. EVC belongs to the short rib-polydactyly group (SRP and these SRPs, especially type III (Verma-Naumoff syndrome, are discussed in the prenatal differential diagnosis. Postnatally, the essential differential diagnoses include Jeune dystrophy, McKusick-Kaufman syndrome and Weyers syndrome. The management of EVC is multidisciplinary. Management during the neonatal period is mostly symptomatic, involving treatment of the respiratory distress due to narrow chest and heart failure. Orthopedic follow-up is required to manage the bones deformities. Professional dental care should be considered for management of the oral manifestations. Prognosis is linked to the respiratory difficulties in the first months of life due to thoracic narrowness and possible heart defects. Prognosis of the final body height is difficult to predict.

  8. Challenging behavior: Behavioral phenotypes of some genetic syndromes

    2014-01-01

    Full Text Available Challenging behavior in individuals with mental retardation (MR is relatively frequent, and represents a significant obstacle to adaptive skills. The frequency of specific forms and manifestations of challenging behavior can depend on a variety of personal and environmental factors. There are several prominent theoretical models regarding the etiology of challenging behavior and psychopathology in persons with MR: behavioral, developmental, socio-cultural and biological. The biological model emphasizes the physiological, biochemical and genetic factors as the potential source of challenging behavior. The progress in the field of genetics and neuroscience has opened the opportunity to study and discover the neurobiological basis of phenotypic characteristics. Genetic syndromes associated with MR can be followed by a specific set of problems and disorders which constitutes their behavioral phenotype. The aim of this paper was to present challenging behaviors that manifest in the most frequently studied syndromes: Down syndrome, Fragile X syndrome, Williams syndrome, Prader-Willi syndrome and Angelman syndrome. The concept of behavioral phenotype implies a higher probability of manifesting specific developmental characteristics and specific behaviors in individuals with a certain genetic syndrome. Although the specific set of (possible problems and disorders is distinctive for the described genetic syndromes, the connection between genetics and behavior should be viewed through probabilistic dimension. The probabilistic concept takes into consideration the possibility of intra-syndrome variability in the occurrence, intensity and time onset of behavioral characteristics, at which the higher variability the lower is the specificity of the genetic syndrome. Identifying the specific pattern of behavior can be most important for the process of early diagnosis and prognosis. In addition, having knowledge about behavioral phenotype can be a landmark in

The prevalence is estimated at approximately 1:40,000 and accordingly, the prevalence of heterozygotes is approximately 1% in Caucasian populations, making it one of the most frequent inherited renal tubular disorders. In the majority of cases, symptoms do not appear before the age of six years and the disease is usually diagnosed during adolescence or adulthood. Transient periods of muscle weakness and tetany, sometimes accompanied by abdominal pain, vomiting and fever are often seen in GS patients. Paresthesias, especially in the face, frequently occur. Remarkably, some patients are completely asymptomatic except for the appearance at adult age of chondrocalcinosis that causes swelling, local heat, and tenderness over the affected joints. Blood pressure is lower than that in the general population. Sudden cardiac arrest has been reported occasionally. In general, growth is normal but can be delayed in those GS patients with severe hypokalemia and hypomagnesemia. GS is transmitted as an autosomal recessive trait. Mutations in the solute carrier family12, member 3 gene, SLC12A3, which encodes the thiazide-sensitive NaCl cotransporter (NCC, are found in the majority of GS patients. At present, more than 140 different NCC mutations throughout the whole protein have been identified. In a small minority of GS patients, mutations in the CLCNKB gene, encoding the chloride channel ClC-Kb have been identified. Diagnosis is based on the clinical symptoms and biochemical abnormalities (hypokalemia, metabolic alkalosis, hypomagnesemia and hypocalciuria. Bartter syndrome (especially type III is the most important genetic disorder to consider in the differential diagnosis of GS. Genetic counseling is important. Antenatal diagnosis for GS

    One of the great advances in clinical medicine was the recognition of the pleomorphism of the immune response and the multiple afferent and efferent limbs of antigen processing and responsiveness. A significant contribution to this understanding was derived from studies of human immunodeficiency states, including both inherited and acquired syndromes. Amongst these syndromes, one of the most common, and least understood, is common variable immune deficiency (CVID). CVID is a syndrome that leads to a reduction in serum immunoglobulins and complications including recurrent infections. Management includes immunoglobulin replacement therapy; however, patients with CVID are at risk for complications of exogenous immunoglobulin administration as well as CVID-associated diseases such as autoimmune processes and malignancies. To assess the current state of knowledge in the field, we performed a literature review of a total of 753 publications covering the period of 1968 until 2008. From this list, 189 publications were selected for discussion. In this review, we demonstrate that while the molecular basis of CVID in many cases remains incompletely understood, significant strides have been made and it is now clear that there is involvement of several pathways of immune activation, with contributions from both T and B cells. Furthermore, despite the current gaps in our knowledge of the molecular pathogenesis of the syndrome, there have been dramatic advances in management that have led to improved survival and significantly reduced morbidity in affected patients.

    Angelman syndrome combines severe mental retardation, epilepsy, ataxia, speech impairment, and unique behavior with happy demeanor, laughing, short attention span, hyperactivity, and sleep disturbance. Occurrence has been calculated at 1:20000 to 1:12000 constituting about 6% of all children with severe mental retardation and epilepsy. The physical "prototype" includes microcephaly with flat neck, fair skin and hair, wide-spaced teeth, and open mouth with tongue protrusion. Epilepsy is characterized by atypical absences, erratic myoclonus, and occasional tonic-clonic seizures. EEG demonstrates high-amplitude 2-3Hz delta activity with spike and slow-wave discharges and sleep-activated generalized epileptiform discharges. Sodium valproate, benzodiazepines, and priacetam are frequently used and effective. Development is generally slow, the majority attaining independent walking in the first 2.5-6 years. Vocabulary is limited to a few single words with superior speech and object apprehension. The condition is due to a lack of expression of the UBE3A gene on chromosome 15q. Maternal deletions of 15q11-13 produce the most pronounced phenotype (65-70% of probands), uniparental disomy and imprinting center mutations (10%), and UBE3A point mutations (11%) produce milder phenotypes.

    In this review we summarize the clinical and genetic aspects of Angelman syndrome (AS), its molecular and cellular underpinnings, and current treatment strategies. AS is a neurodevelopmental disorder characterized by severe cognitive disability, motor dysfunction, speech impairment, hyperactivity, and frequent seizures. AS is caused by disruption of the maternally expressed and paternally imprinted UBE3A, which encodes an E3 ubiquitin ligase. Four mechanisms that render the maternally inherited UBE3A nonfunctional are recognized, the most common of which is deletion of the maternal chromosomal region 15q11-q13. Remarkably, duplication of the same chromosomal region is one of the few characterized persistent genetic abnormalities associated with autistic spectrum disorder, occurring in >1-2% of all cases of autism spectrum disorder. While the overall morphology of the brain and connectivity of neural projections appear largely normal in AS mouse models, major functional defects are detected at the level of context-dependent learning, as well as impaired maturation of hippocampal and neocortical circuits. While these findings demonstrate a crucial role for ubiquitin protein ligase E3A in synaptic development, the mechanisms by which deficiency of ubiquitin protein ligase E3A leads to AS pathophysiology in humans remain poorly understood. However, recent efforts have shown promise in restoring functions disrupted in AS mice, renewing hope that an effective treatment strategy can be found.

    Chromosome 11q13 deletion syndrome has been previously reported as either otodental syndrome or oculo-oto-dental syndrome. The otodental syndrome is characterized by dental abnormalities and high-frequency sensorineural hearing loss, and by ocular coloboma in some cases. The underlying genetic defect causing otodental syndrome is a hemizygous microdeletion involving the FGF3 gene on chromosome 11q13.3. Recently, a new form of severe deafness, microtia (small ear) and small teeth, without the appearance of eye abnormalities, was also reported. In this report, we describe a 1-year-old girl presenting with ptosis of the left upper eyelid, right auricular deformity, high-arched palate, delayed dentition, simian line on the right hand, microcephaly, and developmental delay. In this patient, we identified a deletion in the chromosome 11q13.2-q13.3 (2.75 Mb) region by using an array-comparative genomic hybridization analysis. The deletion in chromosome 11q13 results in a syndrome characterized by variable clinical manifestations. Some of these manifestations involve craniofacial dysmorphology and require a functional workup for hearing, ophthalmic examinations, and long-term dental care. PMID:28018436
