    Cysts overlying the temporal lobes have been well described in literature. These are often associated with agenesis of the temporal lobes, and of major neurosurgical interest due to their frequent association with subdural hematoma, a combination that is rarely seen with cysts in other regions. Full features of plain, angiographic, and CT findings of arachnoid cyst with temporal lobe agenesis accompanying isodense subdural hematoma are presented, being very rare in radiologic literature.

    Most subdural hematomas with significant differed attenuation from that of adjacent brain tissue can be accurately diagnosed by CT. Difficulty arises when the hematoma is isodense that is exhibited similar attenuation to that of brain. Unilateral isodense subdural hematoma can be identified by indirect sign such as mass effect. Occasionally, the use of intravenous contrast material to aid in identifying isodense subdural hematomas has met with variable success. Moreover, bilateral isodense subdural hematoma may be more difficult. We therefore considered it of interest to evaluate the diagnostic efficiency of CT in isodense subdural hematomas. We have analysed 13 cases surgically provened cases of isodense subdural hematoma examined at Korea General Hospital from October 1981 to April 1982. The results were as follows: 1. One hundred twenty seven cases of subdural hematomas were studied by CT, 13 cases (10.2%) of which were isodense. 2. The age distribution was from 29 years to 69 years and mean age was 52 years. The sex ratio was 11 male to 2 female. 3. Seven (53.8%) of 13 cases has a history of head trauma. 4. The time interval which subdural hematoma became isodense was from 1 week to 4 months and peak time interval was from 1 week to 3 weeks. 5. The precontrast CT scan of isodense subdural hematoma appeared shifting of midline structure, compression and deformity of the ventricles in all 13 cases, effacement of cerebral sulci in 10 cases (76.9%) and dilatation of contralateral ventricles in 4 cases (30.8%). 6. The postcontrast CT scan demonstrated enhancement of the medial margin of the lession in 4 (30.8%) of 13 cases and displacement of cortical vein away from the inner table of the skull in 3 (23.1%) of 13 cases. 7. Bilateral isodense subdural hematomas were 2 (15.4%) of 13 cases

    A 69-year-old male was admitted complaining of gait disturbances and diplopia, 2.5 years after an episode of serous meningitis. Neurological examination on admission disclosed Parinaud's sign, unsteady gait and dysdiadochokinesis on the left side. A striking finding on the computerized tomography (CT) was the left to right shift of the posterior portion of the third ventricle without visualization of the quadrigeminal and ambient cisterns, which were almost completely occupied by an isodense mass accompanied by high dense flecks and a low dense part. Enhanced CT showed positive enhancement in the vicinity of the pineal calcification. By the suboccipital supracerebellar approach, an encapsulated mass containing brownish yellow fluid was subtotally removed and a histological examination of it revealed epidermoid tissue and hemosiderin deposits in the solid portion. Few reports of isodense epidermoid cysts have so far been found in the literature giving a full explanation for this unusual CT attenuation value. Based on the clinical course and histology of this case, the pathogenesis of the unusual density is discussed along the following lines: The mixture of the low dense factor due to cholesterin and the high dense factor due to prior bleeding is believed to result in the isodense attenuation value in the liquid portion. Also, in the solid part, a microscopically mixed texture of deposited hemosiderin and cholesterin clefts in the inflammatory granulomatous tissue could explain its density on the CT scan. (author)

    Dorsal pancreatic agenesis is a very rare congenital anomaly. Unilateral renal agenesis, on the other hand, is a relatively common congenital anomaly, although its etiology is not fully understood. Renal and pancreatic embryologic development appears to be nonrelated. We report a case of a 34-year-old man who was referred to our hospital for evaluation of cholestasis and microalbuminuria. Ultrasound and magnetic resonance imaging examinations showed empty right renal fossa and absence of the pancreatic neck, body, and tail. Our case report is the second case of a dorsal pancreatic agenesis and unilateral renal agenesis in a young male patient.

    The area of isodensity contours in a smoothed density field can be measured by the contour-crossing statistic N1, the number of times per unit length that a line drawn through the density field pierces an isodensity contour. The contour-crossing statistic distinguishes between Gaussian and non-Gaussian fields and provides a measure of the effective slope of the power spectrum. The statistic is easy to apply and can be used on pencil beams and slices as well as on a three-dimensional field. 10 references

    Tracheal agenesis is a rare and usually lethal anomaly. In the past, opaque contrast medium was injected via the esophagus to demonstrate the anatomy. To demonstrate the utility of helical and multidetector CT in delineating the aberrant anatomy in newborns with tracheal agenesis. Four newborns with tracheal agenesis were identified from three institutions. Imaging studies and medical records were reviewed. Each child was imaged with chest radiography. One child was imaged on a single-detector helical CT scanner and the other three on multidetector scanners. Helical and multidetector CT with 2D and 3D reconstructions clearly delineated the aberrant tracheobronchial and esophageal anatomy in each infant. Minimum intensity projection reformatted CT images were particularly helpful. One infant each had type I and type II tracheal agenesis. Two infants had type III tracheal agenesis. All four infants died. CT is a useful tool for delineating the aberrant anatomy of newborns with tracheal agenesis and thus helps in making rational clinical decisions. (orig.)

    Sacral agenesis is a central component in the spectrum of anomalies comprising the caudal regression syndrome. Sacral agenesis occurs more frequently in an infant born to mother of diabetes, rubella infection in first trimester than normal mothers. In a patient of sacral agenesis, it is important to recognize the neurologic deficit, neurogenic bladder dysfunction and other congenital anomalies. A case of partial sacral agenesis of 10 years old girl and another case of complete total agenesis associated with multiple anomalies in autopsied newborn are reported.

    Full Text Available Background: Pulmonary agenesis is a rare anomaly (1 in 15 000 live births which consists in a total absence or severe hypoplasia of one or both lungs. The clinical spectrum of the unilateral agenesis could vary from early and severe respiratory distress, recurrent pneumonia to being an incidental finding. The prognosis is based on the presence of associated congenital abnormalities. Material and methods: We present two cases of unilateral pulmonary agenesis in patients at Tlaxcala’s Children Hospital during 2012. Results: Report details the case of a one-month old boy with left pulmonary agenesis and interatrial communication and mild pulmonary arterial hypertension. He had two resolved pneumonia incidents. The other case was a one-month old girl with right pulmonary agenesis, associated to multiple heart malformations who evolved to respiratory failure, heart failure and death.Conclusions: Pulmonary agenesis is a rare anomaly. Its outcome and prognosis varies with the hemodynamics related to its location and associated malformations.

    2017-01-01

    Congenital agenesis of lumbar vertebrae was diagnosed in a day-old female lamb based on radiology and clinical examinations. There was no neurological deficit in hindlimb and forelimb associated with standing disability. Radiography of the abdominal region revealed absence of lumbar vertebrae. Necropsy confirmed clinical and radiographic results. No other anomaly or agenesis was seen macroscopically in the abdominal and thoracic regions as well as vertebral column. Partial absence of vertebral column has been reported in human and different animal species, as an independent occurrence or associated with other organs anomalies. The latter has been designated as caudal regression syndrome. Vertebral agenesis may arise from irregularity in the differentiation of somites to the sclerotome or sclerotome to the vertebral primordium. Most of the previously reported cases of agenesis were related to the lumbosacral region, lonely or along with other visceral absences. This case was the first report of congenital agenesis of lumbar vertebrae in a lamb.

    Full Text Available Abstract Background Alterations in the normal sequence of development of müllerian ducts lead to a wide spectrum of reproductive tract abnormalities. A rare form of lack of development, regarding a short tract of the müllerian ducts, leads to the isolated agenesis of the uterine cervix. Anomalies identified among patients with müllerian agenesis include skeletal deformities (i.e., scoliosis of the spine and Klippel-Feil anomaly. Case presentation A 46 years old woman presenting cyphoscoliosis and very low stature (120 cm – 3,93 feet, came to our observation for acute pelvic pain; she also reported primary amenorrhoea associated with cyclic pelvic pain. Clinical and imaging evaluation, evidenced a blind vaginal duct of normal length, left cystic adnexal mass, and enlarged uterus with hematometra. FSH, LH, 17β estradiol and CA-125, karyotype and radiographic study of limbs and vertebral column were also evaluated. At laparotomy, a left ovarian cyst was found. Uterus ended at the isthmus; under this level a thin fibrous tissue band was found, joining the uterus to the vagina. Uterine cervix was replaced by fibrous tissue containing some dilated glands lined with müllerian epithelium. Karyotype resulted 46, XX. The described skeletal deformity, were consistent with Klippel-Feil syndrome. Conclusion We report a case of congenital scoliosis associated with müllerian agenesis limited to uterine cervix, association thus far seen only among patients with Mayer-Rokitansky-Kuster-Hauser syndrome (utero-vaginal agenesis. This case report supports the necessity to evaluate, for accompanying müllerian anomalies, all cases of congenital structural scoliosis in view of the possibility for many müllerian development abnormalities, if timely diagnosed, to be surgically corrected.

    The objectives of this study were to evaluate the prevalence of dental anomalies in patients with agenesis of maxillary lateral incisors and to compare the findings with the prevalence of these anomalies in the general population. A sample of 126 patients, aged 7 to 35 years, with agenesis of at least 1 maxillary lateral incisor was selected. Panoramic and periapical radiographs and dental casts were used to analyze other associated dental anomalies, including agenesis of other permanent teeth, ectopia of unerupted permanent teeth, microdontia of maxillary lateral incisors, and supernumerary teeth. The occurrence of these anomalies was compared with prevalence data previously reported for the general population. Statistical testing was performed with the chi-square test (P <0.05) and the odds ratio. Patients with maxillary lateral incisor agenesis had a significantly increased prevalence rate of permanent tooth agenesis (18.2%), excluding the third molars. The occurrence of third-molar agenesis in a subgroup aged 14 years or older (n = 76) was 35.5%. The frequencies of maxillary second premolar agenesis (10.3%), mandibular second premolar agenesis (7.9%), microdontia of maxillary lateral incisors (38.8%), and distoangulation of mandibular second premolars (3.9%) were significantly increased in our sample compared with the general population. In a subgroup of patients aged 10 years or older (n = 115), the prevalence of palatally displaced canines was elevated (5.2%). The prevalences of mesioangulation of mandibular second molars and supernumerary teeth were not higher in the sample. Permanent tooth agenesis, maxillary lateral incisor microdontia, palatally displaced canines, and distoangulation of mandibular second premolars are frequently associated with maxillary lateral incisor agenesis, providing additional evidence of a genetic interrelationship in the causes of these dental anomalies. 2010 American Association of Orthodontists.

    Congenital agenesis of the gallbladder is a rare anomaly which is usually asymptomatic and found incidentally. In some cases, however, patients are symptomatic. Common symptoms include right upper quadrant abdominal pain, nausea, and vomiting. Jaundice is present in some symptomatic cases and is due to associated choledocholithiasis (Fiaschetti et al. 2009). In this case, a 63-year-old female presents with jaundice and episodic right upper quadrant abdominal pain with nausea and vomiting. Bilirubin and alkaline phosphatase were found to be markedly elevated. Upper endoscopic ultrasound (EUS) revealed choledocholithiasis, and the patient required multiple endoscopic retrograde cholangiopancreatography (ERCP) sessions before successful extraction of all stones. Subsequent surgical exploration revealed congenital agenesis of the gallbladder. Although this is a rare finding, patients with agenesis of the gallbladder are at increased risk of developing de novo choledocholithiasis which may be challenging to extract.

    An 86-year-old man was admitted to our department with complaints of intermittent upper abdominal pain. Ultrasonography of the abdomen showed dilated extrahepatic bile ducts containing stones; however, the gallbladder was not clearly identified. Magnetic resonance cholangiopancreatography showed dilated extrahepatic ducts and choledocholithiasis without gallbladder visualization. The stone extraction was performed with endoscopic sphincterotomy. Three-dimensional images using spiral-computed tomography after intravenous-infusion cholangiography clearly demonstrated an obstruction of the cystic duct. The patient was scheduled for laparoscopic cholecystectomy. At laparoscopy, the gallbladder fossa was not identified on the undersurface of the liver. Despite a thorough examination of the intrahepatic (left-sided within the lesser omentum), retroperitoneal, retrohepatic (within the falciform ligament), retroduodenal, and retropancreatic areas using laparoscopic ultrasonography, the gallbladder was not found. After careful dissection of the hepatoduodenal ligament, the dilated extrahepatic bile duct and a 1-cm length of hypoplastic cystic duct were found. Gallbladder agenesis is usually accompanied by the lack of the cystic duct. The present case is the third report of gallbladder agenesis with a patent or hypoplastic cystic duct.

    During the last 100 years in medical literature, there are only 54 reports, including the report of Pasaoglu et al (World J Gastroenterol 2008; 14: 2915-2916), with clinical descriptions of agenesis of the dorsal pancreas in humans. Agenesis of the dorsal pancreas, a rare congenital pancreatic malformation, is associated with some other medical conditions such as hyperglycemia, abdominal pain, pancreatitis and a few other diseases. In approximately 50% of reported patients with this congenital malformation, hyperglycemia was demonstrated. Evaluation of hyperglycemia and diabetes mellitus in all patients with agenesis of the dorsal pancreas including description of fasting blood glucose, oral glucose tolerance test, glycated hemoglobin and medical treatment would be a future goal. Since autosomal dominant transmission has been suggested in single families, more family studies including imaging technologies with demonstration of the pancreatic duct system are needed for evaluation of this disease. With this letter to the editor, we aim to increase available information for the better understanding of this rare disease. PMID:19140241

    Full Text Available OBJECTIVE: The aim of the study was to investigate the association between prenatal exposure to AEDs and the risk of dental agenesis and to differentiate between the possible effects of the different drugs used. METHODS: Data on 214 exposed and 255 unexposed children, aged 12-18 years, were extracted from the Prescription Database of the Central Denmark Region and North Denmark Region and the Danish Medical Birth Registry. The children's dental charts were examined for the presence of dental agenesis. RESULTS: Overall, children exposed to AED in utero had an increased risk of developing dental agenesis, but as a group, the difference was not significant (OR = 1.7; [95% CI: 0.8-3.6]. The risk of developing dental agenesis was three-fold increased (OR = 3.1; [95% CI: 1.3-7.4] in children exposed to valproate in mono- or in poly-therapy with other AEDs than carbamazepine or oxcarbazepine. The risk was further increased (OR = 11.2; [95% CI: 2.4-51.9] in children exposed to valproate and carbamazepine or oxcarbazepine in combination. CONCLUSIONS: The present study shows that dental agenesis is a potential congenital abnormality that is related to prenatal exposure to valproate, and dental agenesis may be considered a sensitive marker for the teratogenicity of valproate.

    Full Text Available Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She was admitted to our clinic with the suspicion of pulmonary artery pathology. Absent perfusion of the left lung with normal ventilation was visualized on scintigraphy. MDCT angiography of pulmonary arteries showed absent left main pulmonary artery with systemic collaterals around left hemithorax. Pulmonary artery agenesis can be asymptomatic and isolated until adulthood. Both scintigraphy and CT angiography images of pulmonary artery agenesis of a patient are rare in the literature. Pulmonary ventilation- perfusion scintigraphy can be used not only for pulmonary embolism but also pathologies involving pulmonary artery and its branches. (MIRT 2012;21:80-83

    The purpose of this study was to evaluate the prevalence of dental anomalies in a subpopulation of orthodontic patients with agenesis of maxillary lateral incisors (MLI). The material of the present study included the records of the 1964 orthodontic patients. Panoramic radiographs and dental casts were used to analyze other associated eight dental anomalies, including agenesis of other teeth, dens invaginatus, dens evaginatus, peg shaped MLI, taurodontism, pulp stone, root dilaceration and maxillary canine impaction. Out of the 1964 patients examined, 90 were found to have agenesis of MLI, representing a prevalence of 4.6%. The most commonly found associated-anomalies were agenesis of other teeth (23.3%), peg-shaped MLIs (15.6%), taurodontism (42.2%), and dilacerated teeth (18.9%). Permanent tooth agenesis, taurodontism, peg-shaped maxillary lateral incisor, and root dilacerations are frequently associated with maxillary lateral incisor agenesis.

    Dental agenesis is the most common developmental anomaly in humans, frequently associated with disorders in dental development and maturation. The purpose of this study is to determine radiographic variations in dental maturation in a group of Venezuelan children with dental agenesis. 1,188 panoramic radiographs, from healthy patients ages 5 to 12 years old were studied for agenesis of permanent teeth. Dental maturation was assessed by relative eruption and dental age according to Nolla, comparing children affected with dental agenesis to a stratified control group selected from the same population, excluding children with premature loss of primary teeth in the left quadrants and unclear radiographs. Descriptive analysis, and differences between means and medians (Student t test, Kruskall-Wallis p=0.05) were performed. Medians for Nolla stages were similar between groups, with delay in tooth formation in the agenesis group for second molars (p<0.05) and maxillary lateral incisors and second premolars. Dental age was significantly underestimated for both groups, -0.89 (±0.78) for the control group and -1.20 (±0.95) for the study group. Tooth eruption was similar between groups. Dental age was significantly delayed in Venezuelan children with dental agenesis, with variable significance for tooth formation of studied teeth.

    The aim of this study was to investigate the frequency of dental anomalies in orthodontic patients with different patterns of third-molar agenesis, comparing them with patients without third-molar agenesis. A sample of 374 patients with agenesis of at least 1 third molar was divided into 4 groups according to the third-molar agenesis pattern, and a control group of 98 patients without third-molar agenesis was randomly selected from the patient archives. Panoramic radiographs and cast models were used to determine the associated dental anomalies, such as hypodontia, hyperdontia, impaction, dilaceration, microdontia, ectopic eruption, transposition, and transmigration. The Pearson chi-square and Fisher exact tests were used to determine the differences in the distribution of the associated dental anomalies among the groups. The prevalence of agenesis of other teeth (11.2%, n = 42) was significantly greater in our study sample (groups 1-4) than in the control group (group 5) (4.1%, n = 4; P dental anomalies in patients with agenesis of 3 and 4 third molars compared with the control group. Permanent tooth agenesis, microdontia of maxillary lateral incisors, and total dental anomalies are more frequently associated with agenesis of 4 third molars than with the presence of third molars.

    Full Text Available To investigate the presence and/or agenesis of third molar (M3 tooth germs in orthodontics patients in Malaysian Malay and Chinese population and evaluate the relationship between presence and/or agenesis of M3 with different skeletal malocclusion patterns and sagittal maxillomandibular jaw dimensions. Pretreatment records of 300 orthodontic patients (140 males and 160 females, 219 Malaysian Malay and 81 Chinese, average age was 16.27±4.59 were used. Third-molar agenesis was calculated with respect to race, genders, number of missing teeth, jaws, skeletal malocclusion patterns and sagittal maxillomandibular jaw dimensions. The Pearson chi-square test and ANOVA was performed to determine potential differences. Associations between various factors and M3 presence/agenesis groups were assessed using logistic regression analysis. The percentages of subjects with 1 or more M3 agenesis were 30%, 33% and 31% in the Malaysian Malay, Chinese and total population, respectively. Overall prevalence of M3 agenesis in male and female was equal (P>0.05. The frequency of the agenesis of M3s is greater in maxilla as well in the right side (P>0.05. The prevalence of M3 agenesis in those with a Class III and Class II malocclusion was relatively higher in Malaysian Malay and Malaysian Chinese population respectively. Using stepwise regression analyses, significant associations were found between Mx (P<0.05 and ANB (P<0.05 and M3 agenesis. This multivariate analysis suggested that Mx and ANB were significantly correlated with the M3 presence/agenesis.

    A 67-year-old man was presented with chest tightness and vomiting of one-week duration. On physical examination bowel sounds were heard on the left chest. Plain chest x-ray, barium swallow and CT gastric scan suggested volvulus with diaphragmatic hernia. At laparotomy there was complete agenesis of the left hemidiaphragm with no diaphragmatic remnants seen and no associated lung hypoplasia. This is an extremely rare condition and careful assessment is needed to differentiate between diaphragmatic hernia and agenesis of diaphragm as more cases could be diagnosed in the future as a result of good perinatal care of agenesis of hemidiaphragm (AHD) and long term survival to adulthood.

    Full Text Available Background: Tooth agenesis is one of the most common developmental anomalies in human, which one or a few teeth are absent because they have never formed, may cause cosmetic or occlusal harm, while severe agenesis which are relatively rare require clinical attention to support and maintain the dental function. Molecular studies have demonstrated that tooth development is under strict genetic control. Purpose: This article want to review the genetic regulating that are responsible for tooth agenesis especially the role of Msx1 and Pax9 in pathogenetic mechanisms of tooth agenesis. Review: Tooth agenesis is a consequence of a qualitatively or quantitatively impaired function of genetic networks, which regulate tooth development. Mutations in Msx1 and Pax9 genes are dominant for tooth agenesis in humans. The Pax9 gene, which codes for a paired domain-containing transcription factor that plays an essential role in the development of mammal dentition, has been associated with selective tooth agenesis in humans and mice. Conclusion: Reduced amount of functional Msx1 or Pax9 protein in the tooth forming cells is able to cause severe and selective tooth agenesis. There are differences in the frequency of agenesis of specific teeth associated with the defects in Msx1 and defects in Pax9.

    The corpus callosum, with its ∼200 million axons, remains enigmatic in its contribution to cognition and behaviour. Agenesis of the corpus callosum is a congenital condition in which the corpus callosum fails to develop; such individuals exhibit localized deficits in non-literal language comprehension, humour, theory of mind and social reasoning. These findings together with parent reports suggest that behavioural and cognitive impairments in subjects with callosal agenesis may overlap with the profile of autism spectrum disorders, particularly with respect to impairments in social interaction and communication. To provide a comprehensive test of this hypothesis, we directly compared a group of 26 adults with callosal agenesis to a group of 28 adults with a diagnosis of autism spectrum disorder but no neurological abnormality. All participants had full-scale intelligence quotient scores >78 and groups were matched on age, handedness, and gender ratio. Using the Autism Diagnostic Observation Schedule together with current clinical presentation to assess autistic symptomatology, we found that 8/26 (about a third) of agenesis subjects presented with autism. However, more formal diagnosis additionally involving recollective parent-report measures regarding childhood behaviour showed that only 3/22 met complete formal criteria for an autism spectrum disorder (parent reports were unavailable for four subjects). We found no relationship between intelligence quotient and autism symptomatology in callosal agenesis, nor evidence that the presence of any residual corpus callosum differentiated those who exhibited current autism spectrum symptoms from those who did not. Relative to the autism spectrum comparison group, parent ratings of childhood behaviour indicated children with agenesis were less likely to meet diagnostic criteria for autism, even for those who met autism spectrum criteria as adults, and even though there was no group difference in parent report of current

    Full Text Available Background : The knowledge of Palmaris longus (PL is a growing interest for its wide role in reconstructive plastic surgeries as a donor tendon for transfer or transplant. The prevalence of the PL agenesis has been well-documented by many authors in different ethnic groups or populations. Many conventional tests for determining the presence of the PL has been described, but lamentably there are many discrepancies in confirming its presence or absence. Slight modifications of the prevailing methods can still give authenticate results. Aim : This prospective study was conducted to determine the incidence of unilateral and bilateral agenesis of PL and its association with sex and side of the limb in the Andhra population of India. Materials and Methods : A total of 942 subjects of both sexes belonging to 18-23 years were used to access the PL using various tendon examination techniques including our modified Schaeffer′s test. The data collected were analyzed by Pearsons χ2 test using SPSS software. Results : Overall agenesis of muscle in both sexes was 264 (28.0%, out of which 40.2% was seen in females and 14.7% in males with the ratio of 3:1. The unilateral agenesis was seen in 70.5% and bilateral agenesis in 29.5% subjects. The left side agenesis was seen in 51.6% and right side in 48.4% subjects. Conclusions : The prevalence of bilateral and unilateral agenesis was more common on left side with a greater likelihood in the female subjects. The proposed technique could bring better results in all subjects and can be implemented in manual examination of PL.

    2016-06-01

    Full Text Available Unilateral pulmonary artery agenesis is a rare congenital anomaly, that may develop in isolation, or in association with other congenital cardiovascular anomalies, such as tetralogy of Fallot, septal defects, right-sided aortic arch, or pulmonary atresia. Left-sided pulmonary artery agenesis is less frequent than the right-sided one. Diagnosis of unilateral pulmonary artery agenesis can be difficult. We report the case of a 15 year-old boy who presented with reduced exercise tolerance, shortness of breath and cyanosis. He was diagnosed with left pulmonary artery agenesis, associated with subaortic-ventricular septal defect, right-sided aortic arch, and severe pulmonary arterial hypertension (PAH, that precluded the surgical repair. Pulmonary vasodilator therapy was initiated in this case. The mortality rate of this rare anomaly is high due to its complications. It is essential to establish an early and correct diagnosis, in order to provide adequate treatment and prevent complications in this disease.

    Background Not much data are available on the natural history of bilateral renal agenesis, as the medical community does not typically offer aggressive obstetric or neonatal care asbilateral renal agenesis has been accepted as a lethal condition. Aim To provide an evidence-based, ethically justified approach to counseling pregnant women about the obstetric management of bilateral renal agenesis. Study design A systematic literature search was performed using multiple databases. We deploy an ethical analysis of the results of the literature search on the basis of the professional responsibility model of obstetric ethics. Results Eighteen articles met the inclusion criteria for review. With the exception of a single case study using serial amnioinfusion, there has been no other case of survival following dialysis and transplantation documented. Liveborn babies die during the neonatal period. Counseling pregnant women about management of pregnancies complicated by bilateral renal agenesis should be guided by beneficence-based judgment informed by evidence about outcomes. Conclusions Based on the ethical analysis of the results from this review, without experimental obstetric intervention, neonatal mortality rates will continue to be 100%. Serial amnioinfusion therefore should not be offered as treatment, but only as approved innovation or research. PMID:28222038

    Pancreatic agenesis is an extremely rare cause of neonatal diabetes mellitus and has enabled the discovery of several key transcription factors essential for normal pancreas and beta cell development. We report a case of a Caucasian female with complete pancreatic agenesis occurring together with semilobar holoprosencephaly (HPE), a more common brain developmental disorder. Clinical findings were later confirmed by autopsy, which also identified agenesis of the gallbladder. Although the sequences of a selected set of genes related to pancreas agenesis or HPE were wild-type, the patient's phenotype suggests a genetic defect that emerges early in embryonic development of brain, gallbladder and pancreas. Developmental defects of the pancreas and brain can occur together. Identifying the genetic defect may identify a novel key regulator in beta cell development.

    We have reported a case of agenesis of the corpus callosum, in which NMR-CT revealed a complete defect of it, and have examined the localization of the speech center of this patient. The patient is a right-handed 26-year-old man who has complained of headache on the parietal region. His neurological examination revealed only a mild mental difficulty (IQ 77). X-ray CT showed the lateral ventricles to be separated widely and the posterior horns dilated, which were compatible with the agenesis of the corpus callosum. Further, NMR-CT has revealed a total agenesis of the corpus callosum. NMR-CT seems to be highly useful for the detection of the degree of the callosal defect. We have carried out the intracarotid amobarbital injection (Wada's test) for the determination of the lateralization of cerebral speech dominance. It had been reported by some authors that when it comes to the cerebral speech dominance, acallosal patients had no difference between each hemisphere. However, our results have demonstrated a left sided dominance. (author)

    Results of three-dimensional (3D) time-dependent Hartree--Fock (TDHF) calculations are presented. The assumptions used in the calculations are summarized. The first reaction considered is /sup 16/O + /sup 16/O at 105 MeV (lab); isodensity contours integrated perpendicular to the reaction plane are shown for several impact parameters as a function of time. Trajectories are also shown, and the kinetics of the reaction is discussed; several other energies were also examined. Most of the deeply inelastic scattering seems to come from small impact parameters. Density contours and trajectories are next shown for /sup 40/Ca + /sup 40/Ca at 278 MeV (lab). Finally, density contours are shown for asymmetric systems: /sup 4/He + /sup 16/O at l = 5 h-bar and 50 MeV (lab) and /sup 16/O + /sup 40/Ca at l = 20, 40, 60, 80 h-bar and 315 MeV (lab). The light fragment seems to maintain the same average number of nucleons with which it started. 25 figures. (RWR)

  16. Securing the airway in a child with tracheal agenesis – an alternative perspective

    Directory of Open Access Journals (Sweden)

    Slavomir Nosal

    2011-03-01

    Full Text Available Tracheal agenesis is an extremely rare, typically fatal congenital anomaly characterised by typical clinical manifestation, failed endotracheal intubation and difficult emergency management. The prognosis and possibility of surgical correction rest on early diagnosis, anatomy, birth weight, and associated anomalies. Tracheal agenesis causes considerable resuscitation difficulties immediately after birth, as tracheal intubation is impossible. Although emergency management, by either bag and mask ventilation or oesophageal intubation, provides some pulmonary gas exchange through tracheo-oesophageal connection, they are associated with overdistension of the stomach and the risk of stomach perforation. We have performed selective intubation of the distal trachea in a child with tracheal agenesis through the tracheo-oesophageal connection with the help of a fibroendoscope. A standard guide wire was passed through the working port of the flexible endoscope and under direct vision was directed through the tracheo-oesophageal connection into the distal trachea. At this point, the endoscope was removed, leaving the guide wire in place. The endotracheal tube size 2 Fr was passed over the guide wire into the distal trachea. The infant showed dramatic improvement and maintained good saturations on mechanical ventilation. The infant was taken for a computed tomography (CT scan, which showed Floyd’s type II tracheal agenesis, the oesophagus connecting with the distal trachea before it bifurcates. The endotracheal tube was seen ending in the carina. Transoesophageal intubation of the short distal segment of the trachea through the tracheo-oesophageal connection might offer a new perspective for short-term securing of the airway in a child with tracheal agenesis and should be considered in any child with suspected tracheal agenesis to buy the time while evaluating the exact anatomy of the anomaly and the possibility of tracheal reconstruction in selected

    Gallbladder agenesis (GBA) is extremely rare in dogs. To describe the history, clinical signs, diagnosis, treatment, and outcomes of dogs with GBA. Seventeen client-owned dogs with GBA. Medical records from 2006 through 2016 were retrospectively reviewed. Dogs were included when GBA was suspected on abdominal ultrasonography and confirmed by gross evaluation. Signalment, clinical signs, clinicopathological data, diagnostic imaging, histopathology, treatment, and outcome were recorded. Dogs were of 6 different breeds, and Chihuahuas (10 of 17) were most common. Median age at presentation was 1.9 (range, 0.7-7.4) years. Clinical signs included vomiting (5 of 17), anorexia (2 of 17), ascites (2 of 17), diarrhea (1 of 17), lethargy (1 of 17), and seizures (1 of 17). All dogs had increased serum activity of at least 1 liver enzyme, most commonly alanine aminotransferase (15 of 17). Fifteen dogs underwent computed tomography (CT) cholangiography; common bile duct (CBD) dilatation was confirmed in 12, without evidence of bile duct obstruction. Gross evaluation confirmed malformation of the liver lobes in 14 of 17 dogs and acquired portosystemic collaterals in 5 of 17. Ductal plate malformation was confirmed histologically in 16 of 17 dogs. During follow-up (range, 4-3,379 days), 16 of 17 dogs remained alive. Dogs with GBA exhibit clinicopathological signs of hepatobiliary injury and hepatic histopathological changes consistent with a ductal plate abnormality. Computed tomography cholangiography was superior to ultrasound examination in identifying accompanying nonobstructive CBD distention. Computed tomography cholangiography combined with laparoscopic liver biopsy is the preferable approach to characterize the full disease spectrum accompanying GBA in dogs.

    A 4-year-old neutered male Chihuahua was presented with a history of anorexia and vomiting. Continuous elevation of liver enzymes was found on repeated blood examinations and the dog was referred to us for further evaluation. The absence of gallbladder was suspected on ultrasonography. Exploratory laparotomy and retrograde cholangiography confirmed gallbladder agenesis and a possible hypoplasia of the right medial and lateral liver lobes. Histologically, proliferation of bile ductules associated with portal fibrosis and pseudolobular formation were apparent in the liver lobes.

    Penile agenesis is an extremely rare anomaly that results from absence of the genital tubercle or its failure to develop into a penis during embryonic life. Associated anomalies of the genitourinary and distal gastrointestinal tracts are frequently present. Imaging modalities, particularly MRI and cystography, play a crucial role in establishing the diagnosis and guiding further management. We report a child with penile agenesis with a urethroanal fistula and a blind-ending anterior urethra who had been reared as a male until presentation. (orig.)

    Assess whether the permanent maxillary canine (MC) has a natural tendency to erupt mesially in children with maxillary lateral incisors agenesis (MLIA), compared to children without agenesis. This retrospective, observational, cross-sectional study consisted of children between 5 and 12 years old divided into three groups: the first group with unilateral MLIA, in which an intraindividual analysis was performed, the second group presented bilateral MLIA, and the third group with patients without agenesis. These last two groups were matched for comparison interindividual, being pared by sex and maturation of the MC. The canine position in the horizontal sector showed a clear mesial positioning of the MC on the agenesis side in individuals with unilateral MLIA (group 1) when compared with the counter lateral side; and in individuals with bilateral MLIA (Group 2) compared with control Individuals without agenesis (group 3). Even with the maintenance of this deciduous tooth in the dental arch, the MC keeps its tendency to mesial eruption. There is a greater tendency for mesial angulation of the maxillary canine in patients with MLIA, regardless of the presence or absence of deciduous lateral incisor.

    Full Text Available Corpus callosum agenesis (CCA was evaluated by ultrasound examination and magnetic resonance imaging (MRI with many studies. Ultrasonography was able to suspect CCA by indirect signs but a definitive diagnosis of CCA was achieved in rare cases. MRI was able to diagnose complete CCA in majority of cases. Additional neurological abnormalities including heterotopia, gyration anomaly, asymmetry of the cerebral hemispheres, and Dandy-Walker variant were documented, as well as an ocular anomaly which was described, by MRI examination. Prenatal counseling for fetal agenesis of the corpus callosum is difficult as the prognosis is uncertain. The association with other cerebral abnormalities increases the likelihood of a poor outcome and ultrasonographic assessment of the fetal brain is limited. We found MRI to be a safe and useful additional procedure to complement ultrasonographic diagnosis or suspicion of CCA.

    Sacral agenesis is an uncommon congenital disorder that involves multiple organs. We studied neurological manifestations of the disease, common associated disorders, and their relation with extent of bony malformation. We investigated neurological manifestations of 50 patients with sacral agenesis. Patients were evaluated for previous procedures, ambulation, limb abnormalities, vertebral alignment, recurrent urinary tract infection, urinary incontinence, dribbling, dimple, lower extremities weakness, myelomeningocele (MMC), and lipomyelomenangocele. Weakness of lower extremities was seen in 37 (74%) patients. Concurrent weakness of proximal and distal muscles of the lower limb was statistically associated with a type of bony aplasia (P = .001). However, paraplegia was seen in only 2 of 44 children over the age of 1, and the rest could walk. Myelodysplastic syndromes were seen in 21 patients. Sacral agenesis is diagnosed in children with concomitant MMC at younger ages and reveals more severe symptoms. Progression of neurological disorders was seen in 19 patients, in all of whom MRI showed tethering of the spinal cord. Urinary disorders including diurnal urinary incontinence (in 30 of 35 children over age 4) and recurrent urinary tract infections (in 37) were also common. Imperforate anus was seen in 11 patients. Twelve children over age 4 reported fecal incontinence, a problem that had statistically significant association with imperforate anus (P = .013). Different disorders can concurrently affect patients with sacral agenesis that may have profound impressions on patients and their families. Early diagnosis, thorough evaluation, and proper intervention are of utmost importance as they can prevent or lessen future complications.

    We report 11 cases of vermian partial agenesis without posterior fossa cyst or hemispheric abnormalities. Characteristic MR signs were: absence of the posterior lobe, hypoplasia of the anterior lobe, a narrow sagittal cleft separating the hemispheres (''buttocks sign'') and fourth ventricle deformity. The main clinical signs were complex oculomotor dysfunction and developmental delay. None of the patients had respiratory symptoms. Consideration is given to the relationship between Joubert syndrome and this entity as well as to embroyological data. (orig.)

    Pancreatic agenesis is a human disorder caused by defects in pancreas development. To date, only a few genes have been linked to pancreatic agenesis in humans, with mutations in pancreatic and duodenal homeobox 1 (PDX1) and pancreas-specific transcription factor 1a (PTF1A) reported in only 5 families with described cases. Recently, mutations in GATA6 have been identified in a large percentage of human cases, and a GATA4 mutant allele has been implicated in a single case. In the mouse, Gata4 and Gata6 are expressed in several endoderm-derived tissues, including the pancreas. To analyze the functions of GATA4 and/or GATA6 during mouse pancreatic development, we generated pancreas-specific deletions of Gata4 and Gata6. Surprisingly, loss of either Gata4 or Gata6 in the pancreas resulted in only mild pancreatic defects, which resolved postnatally. However, simultaneous deletion of both Gata4 and Gata6 in the pancreas caused severe pancreatic agenesis due to disruption of pancreatic progenitor cell proliferation, defects in branching morphogenesis, and a subsequent failure to induce the differentiation of progenitor cells expressing carboxypeptidase A1 (CPA1) and neurogenin 3 (NEUROG3). These studies address the conserved and nonconserved mechanisms underlying GATA4 and GATA6 function during pancreas development and provide a new mouse model to characterize the underlying developmental defects associated with pancreatic agenesis.

    : Dilator therapy has been used successfully for many years to treat vaginal agenesis. Our objective was to show how established physical therapy techniques can be used to augment dilator therapy. : A 36-year-old woman desiring nonsurgical management of vaginal agenesis was instructed in the use of vaginal dilators by a pelvic-floor physical therapist. Manual stretching of the vaginal tissues was performed during office visits after application of heat and therapeutic ultrasound to the perineum. In addition, the patient's husband was taught how to perform the vaginal stretching at home in conjunction with dilator therapy. : The patient was able to attempt intercourse after 6 weeks of treatment and achieved full penetration by 9 weeks. At the completion of treatment, she scored 31.9 on the Female Sexual Function Index. The patient and her husband were very satisfied with the treatment approach, especially the encouragement and guidance received in physical therapy. : By using established physical therapy techniques in conjunction with dilator therapy, a faster time to intercourse may be achieved with high patient and spouse satisfaction. We recommend the involvement of a physical therapist specializing in the pelvic floor as an adjunct to standard dilator therapy in the treatment of vaginal agenesis.

    Isolated distal vaginal agenesis is a rare anomaly and mostly becomes symptomatic after menarche. We describe an unusual presentation of this anomaly in a prepubertal girl. An 11-year-old prepubertal girl presented with recurrent urinary tract infection, pyuria, and right-sided renal agenesis. The findings of perineal inspection, ultrasonography, and magnetic resonance imaging were consistent with a distal vaginal agenesis with pyometrocolpos. Discharging pyometrocolpos with dissection of the atretic portion and a pull-through vaginoplasty were performed. A cystoscopy showed no sign of a vesicovaginal or uterine fistula. This rare presentation of distal vaginal agenesis reminds us that congenital malformations of the female genital tract should be considered in patients with congenital anomalies of the urinary system and/or recurrent urinary tract infection, even during the prepubertal period.

    Tooth agenesis is one of the most common congenital anomalies in humans. However, the etiology of tooth agenesis remains largely unclear, as well as evidence base useful for genetic counseling. Therefore, we estimated the prevalence and sibling recurrence risk, and investigated agenetic patterns systematically. Tooth agenesis was classified into two subtypes: hypodontia (one to five missing teeth) and oligodontia (six or more missing teeth). The prevalence of these two subtypes were 6.8% [95% confidence interval (CI): 6.1-7.7%] and 0.1% (95% CI: 0.04-0.3%), respectively, and sibling recurrence risk of these were 24.5% (95% CI: 13.8-38.3%) and 43.8% (95% CI: 26.4-62.3%), respectively. This result suggests that the severe phenotype, oligodontia, might be mostly transmitted in a dominant fashion. Using a simple statistical modeling approach, our data were found to be consistent with a bilateral symmetry model, meaning that there was equal probability of missing teeth from the right and left sides. © 2014 John Wiley & Sons A/S.

  16. Agenesis of the dorsal pancreas: systematic review of a clinical challenge

    Directory of Open Access Journals (Sweden)

    Javier A. Cienfuegos

    Full Text Available Background: Agenesis of the dorsal pancreas is a rare malformation. Since 1911 and until 2008, 53 cases have been reported. Several authors have recently described the association of this anomaly with neoplasia of the ventral pancreas, thus we performed a systematic review of the literature from 2008 to 2015. Methods: A systematic review of the Medline and ISI Web of Science Databases from 2008 until 2015 was carried out, and 30 articles which met the inclusion criteria were identified that included a total of 53 patients: 7 children and 46 adults. Conclusions: Although dorsal pancreatic agenesis is a rare malformation, given its association with non-alcoholic pancreatitis and neoplasia of the residual pancreas, physicians should maintain an expectant attitude.

    Osteogenesis imperfecta (OI) is a heterogeneous group of disorders of connective tissue, mainly caused by mutations in the collagen type I genes (COL1A1 and COL1A2). Tooth agenesis is a common feature of OI. We investigated the association between tooth agenesis and collagen type I mutations in individuals with OI. In this cohort study, 128 unrelated individuals with OI were included. Panoramic radiographs were analyzed regarding dentinogenesis imperfecta (DGI) and congenitally missing teeth. The collagen I genes were sequenced in all individuals, and in 25, multiplex ligation-dependent probe amplification was performed. Mutations in the COL1A1 and COL1A2 genes were found in 104 of 128 individuals. Tooth agenesis was diagnosed in 17% (hypodontia 11%, oligodontia 6%) and was more frequent in those with DGI (P = 0.016), and in those with OI type III, 47%, compared to those with OI types I, 12% (P = 0.003), and IV, 13% (P = 0.017). Seventy-five percent of the individuals with oligodontia (≥6 missing teeth) had qualitative mutations, but there was no association with OI type, gender, or presence of DGI. The prevalence of tooth agenesis is high (17%) in individuals with OI, and OI caused by a qualitative collagen I mutation is associated with oligodontia. © 2016 John Wiley & Sons A/S.

    Hereditary motor and sensory neuropathy associated with agenesis of the corpus callosum (OMIM 218000) is an autosomal recessive disease of early onset characterized by a delay in developmental milestones, a severe sensory-motor polyneuropathy with areflexia, a variable degree of agenesis of the corpus callosum, amyotrophy, hypotonia, and cognitive impairment. Although this disorder has rarely been reported worldwide, it has a high prevalence in the Saguenay-Lac-St-Jean region of the province of Quebec (Canada) predominantly because of a founder effect. The gene defect responsible for this disorder recently has been identified, and it is a protein-truncating mutation in the SLC12A6 gene, which codes for a cotransporter protein known as KCC3. Herein, we provide the first extensive review of this disorder, covering epidemiological, clinical, and molecular genetic studies.

    Aim: To highlight the variation in clinical manifestations, imaging and management of four cases of unilateral pulmonary artery agenesis presenting in adulthood. Method: Four patients with unilateral pulmonary artery agenesis were referred to our institution between 1995 and 2005. They underwent a series of investigations, including chest radiography, echocardiography, ventilation perfusion scintigraphy, angiography, computed tomography (CT) and magnetic resonance imaging (MRI). Results: Two of the four patients had absence of the right main pulmonary artery, whilst the remaining two patients had absence of the left main pulmonary artery. One patient showed a restrictive defect on pulmonary function tests. Two patients who had ventilation perfusion scintigraphy showed absent perfusion and reduced ventilation on the affected side. Angiography (where performed), CT and MRI confirmed the anatomy and the presence of multiple collaterals. Bronchiectasis was demonstrated on CT in two patients, with one also demonstrating a mosaic attenuation pattern. One patient had an incidental lung tumour on the side of the agenesis, which was diagnosed as a chondroid hamartoma on histology. Three of the four patients eventually underwent resection of the affected lung. Conclusion: Isolated unilateral pulmonary artery agenesis has a non-specific presentation. Awareness of this condition can lead to earlier diagnosis, with cross-sectional imaging making an important contribution

    Full Text Available The presence of cervicovaginal agenesis with unicornuate uterus is a very rare mullerian anomaly. Its true incidence is still unknown. The presence of functioning unicornuate uterus poses a great challenge for a gynecologist because a successful repair could restore normal menses and may preserve a patient′s fertility. Hence, we report a case of 16-year-old unmarried female who presented with chief complaints of primary amenorrhea with cyclical lower abdominal pain. On clinical and radiological evaluation, she was diagnosed with complete cervicovaginal agenesis with right unicornuate uterus (hematometra and hematosalpinx. She underwent vaginoplasty (McIndoes method along with uterovaginal anastomosis by neocervix formation, in order to preserve her uterus. On follow-up, her vagina was completely healed, and she was menstruating normally.

    Full Text Available Turner′s syndrome also called as Ullrich Turner′s syndrome, is a disease of unclear pathogenesis characterized by complete or partial absence of one sex chromosome, with or without cell line mosaicism in a phenotypic female with short stature. Various anomalies result in a constellation of features, of which the most disturbing is primary amenorrhea due to gonadal dysgenesis. Hormone therapy in these patients can often result in successful menstruation, and scope for subsequent pregnancy because of anatomically normal uterus and vagina. Coexisting Mullerian agenesis in these patients can jeopardize the chances of future pregnancy as they have associated structural abnormalities of the uterus and vagina. We report a rare case of middle-aged female with Turner′s syndrome and Mullerian agenesis having absent secondary sexual characters and missing uterus with incompletely formed vagina.

    2016-01-01

    Full Text Available The survival rates of patients suffering from various childhood neoplasms have improved dramatically with the advent of chemo-radiation therapy. The harmful effects of chemo-radiation therapy in the oro-facial region such as root agenesis, short roots, impaired amelogenesis, dentinogenesis, radiation caries, and other soft tissue pathologies are well recognized. In spite of these documented risks, the antineoplastic treatment modalities continue to serve the patient for overall improvement in survival and quality of life. However, a thorough understanding of the growth and development process and its relation with the complex antineoplastic treatment is very important for all clinicians. Such awareness could significantly improve the status of patients in the posttreatment period with the implementation of proper preventive and interceptive measures. This article intends to document a case of root agenesis that developed secondary to chemo-radiation therapy in a 12-year-old girl.

    -Related Quality of Life (OHRQoL) in subjects with tooth agenesis. MATERIAL AND METHODS: In nine females and nine males (32 + or - 10 years) with agenesis treated with one to four ISSC (68% in the premolar region), the treatment effect and masticatory function were assessed. The evaluation was performed first...... after implant placement shortly before crown cementation, and again 1 month after cementation. It consisted of questionnaires [including Oral Health Impact Profile (OHIP-49)] and functional examination with plastic strips, the Dental Prescale Film and the Occluzer system, Xylitol color-changeable gum...... with ISSCs in subjects with tooth agenesis significantly increased masticatory function subjectively and clinically as well as OHRQoL. However, as the functional parameters before replacement of the teeth corresponded to values in subjects with complete dentitions, the functional importance of the increase...

    The aims of this study were to (1) investigate if there is a difference in skeletal maturation between tooth agenesis and control patients and (2) whether skeletal maturation is affected by the severity of tooth agenesis. The cervical vertebral maturation (CVM) index can be used to assess skeletal maturation. A retrospective cross-sectional study. Eastman Dental Hospital, London, UK. A total of 360 cephalograms of patients aged 9-17 years (164 males and 196 females) allocated to four subgroups (mild, moderate and severe tooth agenesis patients, and controls) were assessed retrospectively. There were 90 patients in each of the four subgroups. The skeletal maturation of each subject was assessed both quantitatively and qualitatively using the CVM index. All patients in the study were either currently receiving treatment or had been discharged from the hospital. There was no statistically significant relationship between skeletal maturation and the presence of tooth agenesis. Furthermore, there was no statistically significant relationship between the skeletal maturity of patients and different severities of tooth agenesis. The data obtained from this group of patients and using this measurement tool alone does not supply sufficient reason to reject the null hypothesis. However, it suggests that it is possible that no difference exists between the groups.

    We analyze experimentally the behavior of a non-Brownian, iso-dense suspension of spheres submitted to periodic square wave oscillations of the flow in a Hele-Shaw cell of gap H. We do observe an instability of the initially homogeneous concentration in the form of concentration variation stripes transverse to the flow. The wavelength of these regular spatial structures scales roughly as the gap of the cell and is independent of the particle concentration and of the period of oscillation. This instability requires large enough particle volume fractions φ≥ 0.25 and a gap large enough compared to the sphere diameter (H/d ≥ 8) . Mapping the domain of the existence of this instability in the space of the control parameters shows that it occurs only in a limited range of amplitudes of the fluid displacement. The analysis of the concentration distribution across the gap supports a scenario of particle migration towards the wall followed by an instability due to a particle concentration gradient with a larger concentration at the walls. In order to account for the main features of this stripes instability, we use the theory of longitudinal instability due to normal stresses difference and recent observations of a dependence of the first normal stresses difference on the particle concentration.

    Full Text Available Introduction: The third molar develops entirely after birth and also it is the last tooth to erupt in all ethnic groups despite racial variations in the eruption sequence. Tooth development with effects on tooth size, shape, position, and total absence is affected due to environmental factors, systemic diseases, genetic polymorphisms, and teratogens. Aims and Objectives: The aim of this study was to assess the prevalence of agenesis, impaction, and pararadicular radiolucencies in relation with third molars. Materials and Methods: One hundred digital orthopantomograph (OPG scans of patients of age ranging from 18 to 25 years were selected randomly from the digital OPG database of the Department of Oral Medicine and Radiology, and then assessment and analysis were carried out. Results: Overall agenesis rate was about 14.5%. Bilateral agenesis of maxillary and mandibular third molars was about 14% and 13%, respectively. Overall impaction rate was about 21.92%. Mesioangular impaction rate was about 57.33% whereas distoangular impaction rate was about 26.66%. Prevalence of pararadicular radiolucencies was only about 0.8% with mandibular predilection. Conclusion: As the agenesis of the third molars is increasing, they can be considered as vestigial. Prevalence of impaction of the third molars is increasing. Pararadicular radiolucencies are mostly seen with mandibular third molar.

    Full Text Available Herlyn-Werner-Wunderlich (HWW syndrome is a rare variant of Müllerian duct anomalies consisting of uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. Patients with HWW syndrome are usually asymptomatic until menarche, when they present with acute lower abdominal pain. Here we report a case of a female newborn with right renal agenesis diagnosed during the pregnancy. The patient presented with a protruding mass over the vaginal introitus that was associated with an obstructed hemivagina and uterine didelphys.

    The aim of this study was to investigate the prevalence of tooth agenesis, microdontia, and tooth malformation among non-syndromic oral cleft patients and their potential association with cleft type and gender. Intraoral records and radiographs of 154 patients (97 males and 57 females) were examined. The variables assessed were tooth agenesis, microdontia, dental malformations, and cleft types. The statistics included chi-square and Fisher's exact tests as well as logistic regression to assess any mutual effects of gender and cleft type on the dental variables. Tooth agenesis occurred in 50% of the sample and microdontia in 18%. Non-statistically significant odds ratios for the association of gender and cleft type with tooth agenesis were obtained. Tooth agenesis was substantially higher at the unilateral right CL + P and the bilateral CL + P in quadrant 1 and at the unilateral left CL + P and bilateral CL + P in quadrant 2. It was also higher, at the isolated cleft palate (CP) in quadrants 3 and 4. These results were attributed to teeth 22 (31.8%) and 12 (21.6%) in the maxilla and to teeth 35 (6.1%) and 45 (5.4%) in the mandible. In unilateral CL + P patients, the cleft quadrant that presented tooth agenesis was associated with the side of the cleft. Interdisciplinary treatment of the oral cleft patients should take into consideration the high prevalence of tooth agenesis and their association with the different cleft types. The most frequently affected teeth by cleft are by far the upper lateral incisors. Results indicate that tooth agenesis appears to be a genetically controlled anomaly related to the orofacial cleft development through various genetic links and not caused by the cleft disruptive process.

    Full Text Available Background and Aim: The purpose of the present study was to investigate the effect of vestibulo-proprioceptive stimulations of sensory integration theory on the development of gross and fine motor, language and personal-social functions in a child with agenesis of the corpus callosum.Case: We report a 10.5 month old boy with agenesis of the corpus callosum. The intervention was administered based on sensory integration theory an hour a week for 20 weeks. The exercise intervention consisted of proprioceptive and linear, sustained and low frequency vestibular stimulations on suspension device and physio roll. A Denver Developmental Screening- II and milestones skill testing was completed pre-intervention and monthly. Post-intervention, age of gross motor, fine motor adaptive, language, and personal-social functions significantly improved. Based on milestones skills, maintenance of gross motor functions (e.g. sitting and quadruped position improved. The child could roll from side to side and released objects voluntarily. The reaction time to auditory stimulations became less than 2 seconds.Conclusion: vestibulo-proprioceptive stimulations using the neuroplasticity ability of the central nervous system is effective for development of gross and fine motor, language, and personal-social functions. These exercises can be administered for a child with agenesis of the corpus callosum.

    Full Text Available Objective: Background: Studies have documented the agenesis of Palmaris longus muscle in different populations but none has included the Ghanaian population. Methods: The study involved 226 subjects (130 females and 96 males who are students of the University of Cape Coast, Cape Coast, Ghana. The presence of the PLM was clinically determined using the Schaeffer’s test. Subjects in which the tendon was not visualized or palpable, two other tests were performed to confirm the absence. Results: The total prevalence of absence of PLM was 3.1%; absence on the left hand was commoner than on the right hand. The frequency of PLM absence was also slightly higher in females than in males representing 1.8% and 1.3% respectively. One female had the PLM absent bilaterally whiles a male subject had a trifid tendon on the right forearm with a bifid on the left. Conclusion: The prevalence of PLM agenesis in the Ghanaian population is lower compared to values coated in standard textbook on surgery. PLM is not diminishing as fast as observed in some population hence it is can be readily used as donor tendon by Ghanaian surgeons.

      The purpose of this study was to assess the presence of the golden proportion (GP) in the facial view tooth-to-tooth width proportion of the six maxillary anterior teeth and to evaluate the width/height (W/H) ratios of the incisors of patients with maxillary lateral incisor (LI) agenesis treated either with implants or orthodontically (by moving canines into the position of the laterals, recontouring them, and placing composite restorations over the repositioned teeth).   Forty-eight patients with LI agenesis were divided into four experimental groups: unilateral recontouring group (N = 10), bilateral recontouring group (BRG, N = 18), unilateral implant group (UIG, N = 10), bilateral implant group (N = 10), and a control group (CG, N = 25) of patients without agenesis. GP ratios were determined on patients' dental casts placed over Levin's grids, whereas W/H ratios were measured directly on the casts and a millimeter ruler to determine these distances. Statistical analysis was performed with Shapiro-Wilk, Kruskal-Wallis, Mann-Whitney, Friedman, and Wilcoxon tests (p mean W/H ratios of the laterals ranged between 0.75 and 0.90.   Although the GP may be a useful diagnostic guide, it was not observed in the majority of esthetic outcomes of patients treated with maxillary LI agenesis in this study. The assessment of the golden proportion and width/height ratio of upper anterior teeth in patients with upper lateral incisor agenesis treated with either implants or tooth re-contouring may assist dentists and patients in deciding the best treatment option based on the peculiarities of each case. © 2012 Wiley Periodicals, Inc.

    Primary septal agenesis (PSA) is a rare brain malformation that can be isolated or part of developmental brain abnormalities (holoprosencephaly, septo-optic dysplasia or cortical malformation). Such associated malformation can be subtle, leading to difficulties in the prenatal management of PSA. Moreover, the neurological prognosis of isolated PSA remains debatable. The aims of the study were to specify the patterns and frequency of brain malformations associated with septal agenesis (SA), to identify the clinical prognosis, and to discuss the aetiology of PSA with the new insights provided by molecular genetics. The study consisted of a 14-year retrospective review of brain MRI in 34 patients having PSA (mean age, 5 years). Chiasm and optic nerves were not evaluated. Post-hydrocephalus SA or incomplete data were excluded. The clinical data were correlated to the MRI patterns. The study disclosed 82.5% associated lesions with MRI (28/34): 11 neuronal migration disorders, 9 holoprosencephalies (HP), 7 pituitary stalk interruptions, 1 corpus callosum partial agenesis; 17.5% (6/34) of cases were apparently isolated PAS. Clinically, the patients had motor dysfunction in 68% (23/34), mental retardation in 65% (22/34), blindness in 24% (8/34), endocrinological defects in 21% (7/34) and epilepsy in 18% (6/34) of cases. Nine percent of patients (3/34) were neurologically normal (including one with scoliosis and two infants younger than 2 years at the last follow-up). Patients with bilateral cortical anomalies and HP (even if mild) had the worst neurological prognosis. A severe motor impairment was present without evidence of hemispheric anomaly in 12% of patients (4/34). Interestingly, the frontal lobes were involved in 90% of cortical anomalies and HP, supporting the malformative aetiology of PSA. PSA rarely appears isolated and severe psychomotor impairment may occur in apparently isolated forms. These unfavourable results should be highlighted and need to be confirmed

    Sirenomelia is a rare congenital abnormality characterized by a variety of anomalies involving the lower limbs, severe oligohydramnios, bilateral renal agenesis, anorectal atresia and aberrant fetal vasculature. The prenatal diagnosis and differentiation from isolated bilateral renal agenesis is severely limited by the accompanying oligohydramnios that hinders visualization of fetal anatomy. We present three prospectively assessed cases of sirenomelia, two of which had bilateral renal agenesis, and all of which had a single umbilical artery derived from the aberrant vasculature that accompanies the syndrome.

    Full Text Available Unilateral absence of pulmonary artery or pulmonary artery agenesis (UAPA is a rare congenital malformation that can present as an isolated lesion or in association with other cardiac anomalies. Though congenital, presentation in adults are also reported. Most common presentation in adults is of exercise intolerance. The developing lung on the affected side is hypoplastic. Diagnosis of UAPA is established by imaging methods like CT and MRI . There is no specific treatment for this condition. Treatment depends on patients symptomatology, presence of pulmonary hypertension and collateral circulation. Presence of pulmonary hypertension carries a bad prognosis. We present two adult patients with isolated left sided unilateral pulmonary artery agenesis with ipsilateral lung hypoplasia. The diagnosis was confirmed by CT chest and perfusion scan.

    Defining the best treatment for maxillary lateral incisor agenesis is a challenge. Our aim in this study was to determine, with the evidence available in the literature, the best treatment for maxillary lateral incisor agenesis in the permanent dentition, evaluating the esthetic, occlusal (functional), and periodontal results between prosthetic replacement and orthodontic space closure. Electronic databases (CENTRAL, PubMed, Web of Science, Scopus, and LILACS) were searched in September 2014 and updated in January 2015, with no restriction on language or initial date. A manual search of the reference lists of the potential studies was performed. Risk of bias was assessed by the Newcastle Ottawa Scale. The search identified 2174 articles, of which 1196 were excluded because they were duplicates. Titles and abstracts of 978 articles were accessed, and 957 were excluded. In total, 21 articles were read in full, and 9 case-control studies were included after applying the inclusion and exclusion criteria. Data were extracted from the articles selected, and a table was compiled for comparison and analysis of the results. There were no randomization and blinding, and the risk of bias evaluation found gaps in compatibility and outcome domains in almost all selected studies. Tooth-supported dental prostheses of maxillary lateral incisor agenesis had worse scores in the periodontal indexes than did orthodontic space closure. Space closure is evaluated better esthetically than prosthetic replacements, and the presence or absence of a Class I relationship of the canines showed no relationship with occlusal function or with signs and symptoms of temporomandibular disorders.

    Full Text Available Development of urogenital anatomy in the human fetus is the result of a complex interplay between multiple different tissues. The time course of development is well documented and the morphologic outcomes of insults at various time points during development are predictable. We present a cadaveric case of unilateral agenesis of the left kidney, ureter, bladder hemitrigone, ureteric opening, seminal vesicle, vas deferens, and epididymis. Failure of development of the mesonephric duct early during embryogenesis, likely between the third and fifth week, caused ipsilateral urogenital organ agenesis.

    What are the anatomic variants (and their frequencies) of double uterus, obstructed hemivagina and ipsilateral renal agenesis? Most cases examined (72.4%) were of the classic anatomic variant of the Herlyn-Werner-Wunderlich syndrome (with didelphys uterus, obstructed hemivagina and ipsilateral renal agenesis) but the 27.6% of cases are of a rare variant of the syndrome (with uterus septum or cervical agenesis), showing relevant clinical and surgical implications. The extreme variability of anatomic structures involved in this syndrome (both uterus, cervico-vaginal and renal anomalies) is well known, even if a complete and uniform analysis of all its heterogeneous presentations in a large series is lacking. This is a retrospective study with 87 patients referred to our third level referral center between 1981 and 2011. We analyzed the laparoscopic and chart records of 87 women, who referred to our institute with double uterus, unilateral cervico-vaginal obstruction and ipsilateral renal anomalies. Sixty-three of 87 patients had the more classic variant of didelphys uterus with obstructed hemivagina; 10/87 patients had septate bicollis uterus with obstructed hemivagina; 9/87 patients had bicornuate bicollis uterus with obstructed hemivagina; 4/87 patients had didelphys uterus with unilateral cervical atresia; 1/87 patients had bicornuate uterus with one septate cervix and unilateral obstructed hemivagina. This is a retrospective study with a long enrolling period (30 years). New insights in the anatomic variants of this rare syndrome with their relevant surgical implications.

    A case of absence of the septum pellucidum accompanied with hydrocephalus in 56 years-old woman who had complained headache, dizziness and numbness of left leg was reported. Absence of the septum pellucidum in this case had not been detected untill CT scan was performed. Ventriculoperitoneal shunt was performed, then her complaints were cleared up. The discussion was limited as far as possible to absence of the septum pellucidum without agenesis of the corpus callosum with a few references. Encephalographic characteristics of absence of the septum pellucidum were firstly noted by Foster in 1935. The real prevelence should lie at about 1 : 400 in a sufficiently large encephalographical series, which should be an estimate between 2 and 3 per 100,000 of population. Encephalography, although, afflicts patients with headache, nausea and vomiting, moreover it accompanied with possible intracranial infection. The other hand, CT scan has cleared up these problems, we can perform it easily in any cases, and know about status of the septum pellucidum. Further examination for more distinct information are took by coronal section and ''high definition 5 mm slice thickness'' of CT scan. (author)

    A 10-month-old female toy poodle was referred to the University of Tokyo Veterinary Medical Center with a urogenital anomaly found during sterilization. An exploratory laparotomy revealed a cyst adhering to the cervix and a unilateral renal agenesis. Histopathology and immunohistochemical analysis of the cyst was consistent with remnants of the Wolffian duct or a Gartner duct cyst. This is a rare case of a canine Gartner duct cyst with renal agenesis and uterine anomaly. We discuss the similarity of this case to that of humans and introduce a classification in the literature for these complex urogenital malformations for further clinical research into the precise diagnosis and appropriate surgical planning.

    We report a case of bilateral pulmonary agenesis (BPA), which was suspected during a prenatal US examination and diagnosed by fetal magnetic resonance imaging (MRI). BPA is an extremely rare congenital anomaly and, although many fetal structural defects can be detected with a high degree of confidence after introducing high-resolution US, the prenatal diagnosis of BPA remains problematic. Other thoracic abnormalities, such as a congenital diaphragmatic hernia, congenital cystic adenomatoid malformation, and pulmonary sequestration, should be excluded from the list of possible diagnoses before coming to the conclusion of BPA, because BPA is absolutely incompatible with extrauterine life, and an accurate internal diagnosis can prevent a futile intervention from being performed.

    2011-11-01

    Full Text Available  Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis (OHVIRA Syndrome is a rare congenital anomaly of the female genital tract. Uterus didelphys occurs when the midline fusion of the mullerian ducts is arrested, either completely or incompletely. Women with didelphic uterus may be asymptomatic and unaware of having a double uterus. They may present with complaints of dysmenorrhoea and dyspareunia. A 25 year old woman attending the infertility clinic at Nizwa regional referral hospital presented with history of dysmenorrhoea and foul vaginal discharge with right cystic pelvic mass. She was diagnosed as a case of double uterus with obstructed right hemivagina and right pyocolpos with ipsilateral renal agenesis after routine ultrasonography in the clinic followed by MRI. Excision of the right vaginal septum with drainage of 200 ml of purulent discharge was performed. She was relieved of her symptoms and conceived promptly after the surgical excision of the partial vaginal septum.

    Full Text Available Agenesis of the inferior vena cava (IVC is a rare anomaly which can be identified as incidental finding or can be associated with iliofemoral vein thrombosis. IVC agenesis has a known association with renal anomalies which are mainly confined to the right kidney. We describe a case of a 14-year-old male who presented with left leg swelling and pain. Ultrasonography confirmed the presence of left leg deep vein thrombosis (DVT. No underlying hematologic risk factors were identified. A CT scan was obtained which demonstrated absent infrarenal IVC and extensive thrombosis in the left deep venous system and development of collateral venous flow into the azygous/hemiazygous system, with extension of thrombus into paraspinal collaterals. An additional finding in the patient was an atrophic left kidney and stenosis of an accessory left renal artery. Agenesis of the IVC should be considered in a young patient presenting with lower extremity DVT, especially in patients with no risk factors for thrombosis. As agenesis of the IVC cannot be corrected, one should be aware that there is a lifelong risk of lower extremity DVT.

    Tooth agenesis is one of the most intriguing phenomena, because it is frequently associated with other oral anomalies, structural variations and malformations of other teeth, late eruption, transposition and crowding. The diagnosis can be quite challenging as radiographic examination is critical for the diagnosis but not always possible and the late developing teeth may be sometimes scored developmentally missing. Accurate diagnosis therefore requires radiographic, clinical, and dental cast examinations. It is an important clinical and public health problem. Patients with missing permanent teeth may suffer from a reduced chewing ability, inarticulate pronunciation, and an unfavorable aesthetic appearance. Clinically, early diagnosis of a dental anomaly can alert the clinician to the possible development of other associated dental anomalies in the same patient or family, and avoid the possible sequelae. Understanding of tooth agenesis patterns and their impact on diagnosis, prevention, and eventually therapeutics are becoming integral parts of comprehensive dental care. Dental examination with radiographic screening of hypodontia in early childhood should be emphasized as part of public oral health policy to allow early diagnosis and timely intervention.

    The aim of this study was to compare the pattern and prevalence of associated dental anomalies between maxillary and mandibular tooth agenesis (hypodontia). A sample of 3315 dental patients, aged 8.6 to 25.4 years, was surveyed for tooth agenesis (excluding third molars): 106 subjects were diagnosed with maxillary hypodontia (group 1) and 70 with mandibular hypodontia (group 2). Both groups were examined for the following dental anomalies: retained deciduous molars, infraocclusion of deciduous molars, impaction, microdontia of maxillary lateral incisors, supernumerary teeth, transposition, transmigration, and ectopic eruption of the permanent molars. For statistical testing, the chi-square test (P anomalies among the groups. We found that 77.5% of the patients in the mandibular hypodontia group had at least 1 dental anomaly compared with 49.5% in the maxillary hypodontia group (P dental anomaly with a significantly increased prevalence in the maxillary hypodontia group compared with the mandibular hypodontia group was microdontia of the maxillary lateral incisors (groups 1, 46.7%; group 2, 12.9%; P dental development in both jaws.

    2010-01-01

    PURPOSE: This study was carried out to determine the prevalence, severity and pattern of hypodontia in Irish patients referred to a tertiary care clinic for developmental dental disorders. MATERIALS AND METHODS: Details of 168 patients with hypodontia referred during the period 2002-2006 were entered in a database designed as a national record. Tooth charting was completed using clinical and radiographic examinations. The age of patients ranged from 7-50 years, with a median age of 20 years (Mean: 21.79; SD: 8.005). RESULTS: Hypodontia referrals constituted 65.5% of the total referrals. Females were more commonly affected than males with a ratio of 1.3:1. The number of referrals reflected the population density in this area; the majority were referrals from the public dental service. Mandibular second premolars were the most commonly missing teeth, followed by maxillary second premolars and maxillary lateral incisors; maxillary central incisors were the least affected. Symmetry of tooth agenesis between the right and left sides was an evident feature. Slightly more teeth were missing on the left side (n = 725) than on the right side (n = 706) and in the maxillary arch (n = 768) as compared to the mandibular arch (n = 663). Some 54% of patients had severe hypodontia with more than six teeth missing; 32% had moderate hypodontia, with four to six teeth missing. The most common pattern of tooth agenesis was four missing teeth. CONCLUSION: Hypodontia was a common presentation in a population referred to this tertiary care clinic. The pattern and distribution of tooth agenesis in Irish patients appears to follow the patterns reported in the literature.

    Agenesis of the dorsal pancreas is a very rare condition with an unknown pathology and etiology, although it may be associated with autosomal dominant or X-linked dominant inheritance or retinoic acid and hedgehog signaling pathway alterations. This condition usually manifests with abdominal pain or pancreatitis, although some cases are asymptomatic. Approximately 50% of affected patients with this disorder present with hyperglycemia or various other anomalies. We report the case of a 23-year-old Chinese woman who visited the Department of Endocrinology and Metabolism with insulin-dependent diabetes but no specific symptoms, signs, or other deformities. Severe diabetic retinopathy indicated a long period of hyperglycemia. Agenesis of the dorsal pancreas was observed incidentally during the common diagnosis of diabetes, and the diagnosis was established using magnetic resonance imaging, diffusion-weighted imaging, and magnetic resonance cholangiopancreatography. Following the diagnosis of diabetes, insulin replacement therapy was initiated at a dosage of up to 45 U per day. The patient's blood glucose level was monitored, and the insulin dosage was adjusted accordingly. The patient's blood glucose levels gradually normalized after insulin treatment and were subsequently maintained with intensive insulin therapy. Treatment for diabetic retinopathy was provided by the Ophthalmology Department. Agenesis of the dorsal pancreas should be considered in a young patient diagnosed with diabetes who presents with obvious diabetes-related complications (e.g., renal, retinal, or neurological) inconsistent with the course of the disease or a history of other congenital anomalies. We recommend the routine use of computed tomography or magnetic resonance imaging when examining young patients with diabetes.

    Caudal regression syndrome is a rare fetal condition of diabetic pregnancy. Although the exact mechanism is not known, hyperglycaemia during embryogenesis seems to act as a teratogen. Independently, caudal regression syndrome (CRS), agenesis of the corpus callosum (ACC) and partial lobar holoprosencephaly (HPE) have been reported in infants of diabetic mothers. To our knowledge, a combination of all these three conditions has not been reported so far. PMID:21509087

    Full Text Available PURPOSE: To illustrate the radiological findings and review the current literature concerning a rare congenital abnormality of the posterior arch of the atlas. CASE REPORT: An adult female without neurological symptoms presented with an absent posterior arch of the atlas, examined with plain films and helical computerized tomography. Complete agenesis of the posterior arch of the atlas is a rare entity that can be easily identified by means of plain films. Although it is generally asymptomatic, atlantoaxial instability and neurological deficits may occur because of structural instability. Computerized tomography provides a means of assessing the extent of this abnormality and can help evaluate the integrity of neural structures. Although considered to be rare entities, defects of the posterior arch of the atlas may be discovered as incidental asymptomatic findings in routine cervical radiographs. Familiarity with this abnormality may aid medical professionals in the correct management of these cases.

    Complex malformations of female genital tract are not so common. Their correct identification is of paramount importance for appropriate management. A thorough knowledge of embryology, pre-operative imaging with MRI and examination under anaesthesia is essential to identify accurately the constellation of anomalies and to plan appropriate management. This case reports the coexistence of Mullerian abnormality with vaginal agenesis in an 18 years old girl which was managed by dissecting the lower half of vagina and pull-through vaginoplasty.

    Full Text Available ABSTRACT The present study reports the treatment carried out in a patient with mandibular second premolar agenesis associated with early loss of a deciduous second molar, deep overbite, severe overjet and dentoalveolar bimaxillary protrusion, which led to lip incompetence and a convex facial profile. The main objectives of this treatment were: to eliminate the spaces in mandibular arch, correct overbite, as well as eliminate bimaxillary protrusion and lip incompetence, thus leading to a balanced profile. The case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO as part of the requirements to obtain the title of BBO diplomate.

  7. Emotional Intelligence in Agenesis of the Corpus Callosum.

    2017-05-01

    People with agenesis of the corpus callosum (AgCC) with normal general intelligence have deficits in complex cognitive processing, as well as in social cognition. It is uncertain the extent to which impoverished processing of emotions may contribute to social processing deficiencies. We used the Mayer-Salovey-Caruso Emotional Intelligence Test to clarify the nature of emotional intelligence in 16 adults with AgCC. As hypothesized, persons with AgCC exhibited greater disparities from norms on tests involving more socially complex aspects of emotions. The AgCC group did not differ from norms on the Experiential subscale, but they were significantly below norms on the Strategic subscale. These findings suggest that the corpus callosum is not essential for experiencing and thinking about basic emotions in a "normal" way, but is necessary for more complex processes involving emotions in the context of social interactions. © The Author 2017.

    Full Text Available Aim: Objective of this study is to report our experience with sigmoid vaginoplasty in adolescents. Materials and Methods: A retrospective study of children with vaginal atresia and Mayer-Rokitansky-Kuster-Hauser syndrome. The sigmoid segment was used for vaginoplasty in all the cases. Results: Eight children were studied over a period of 7 years. The postoperative complications were ileus in 2, mucosal prolapse of the neovagina in 1, and minor wound infection in 1 patient. Seven patients are on regular follow-up. All the neovaginas were patent and functional. One patient had unacceptable perineal appearance, that is, badly scarred perineum as a late complication. None of the patients had vaginal stenosis or excessive mucus discharge, during follow-up visits. Out of the 7 patients, 2 patients are sexually active and satisfied. Conclusions: Sigmoid vaginoplasty is a safe and acceptable procedure for vaginal agenesis with good cosmetic results and acceptable complications rate. Sigmoid colon vaginoplasty is the treatment of choice because of its large lumen, thick walls resistant to trauma, adequate secretion allowing lubrication, not necessitating prolonged dilatation, and short recovery time.

    Full Text Available Abstract Background Partial Trisomy 11q syndrome (or Duplication 11q has defined clinical features and is documented as a rare syndrome by National Organization of Rare Disorders (NORD. Deletion 1q44 (or Monosomy 1q44 is a well-defined syndrome, but there is controversy about the genes lying in 1q44 region, responsible for agenesis of the corpus callosum. We report a female child with the rare Partial Trisomy 11q syndrome and Deletion 1q44 syndrome. The genomic imbalance in the proband was used for molecular characterization of the critical genes in 1q44 region for agenesis of corpus callosum. Some genes in 11q14q25 may be responsible for laryngomalacia. Results We report a female child with dysmorphic features, microcephaly, growth retardation, seizures, acyanotic heart disease, and hand and foot deformities. She had agenesis of corpus callosum, laryngomalacia, anterior ectopic anus, esophageal reflux and respiratory distress. Chromosome analysis revealed a derivative chromosome 1. Her karyotype was 46,XX,der(1t(1;11(q44;q14pat. The mother had a normal karyotype and the karyotype of the father was 46,XY,t(1;11(q44;q14. SNP array analysis showed that the proband had a 54 Mb duplication of 11q14q25 and a 0.9 Mb deletion of the submicroscopic subtelomeric 1q44 region. Fluorescence Insitu Hybridisation confirmed the duplication of 11qter and deletion of 1qter. Conclusion Laryngomalacia or obstruction of the upper airway is the outcome of increased dosage of some genes due to Partial Trisomy 11q Syndrome. In association with other phenotypic features, agenesis of corpus callosum appears to be a landmark phenotype for Deletion 1q44 syndrome, the critical genes lying proximal to SMYD3 in 1q44 region.

    Constitutional mismatch repair deficiency syndrome is a cancer predisposition syndrome caused by autosomal recessive biallelic (homozygous) germline mutations in the mismatch repair genes (MLH1, MSH2, MSH6, and PMS2). The clinical spectrum includes neoplastic and non-neoplastic manifestations. We present the case of a 7-year-old boy who presented with T-lymphoblastic lymphoma and glioblastoma, together with non-neoplastic manifestations including corpus callosum agenesis, arachnoid cyst, developmental venous anomaly, and hydrocephalus. Gene mutation analysis revealed pathogenic biallelic mutations of PMS2 and heterozygous DICER1 variant predicted to be pathogenic. This report is the first to allude to a possible interaction of the mismatch repair system with DICER1 to cause corpus callosum agenesis.

    2010-01-01

    The objective of this study was to review our experience with female children who have unilateral renal agenesis or renal dysplasia associated with cystic lesions in the reproductive system. Between 1991 and 2007, we treated 26 patients with unilateral renal agenesis or renal dysplasia associated with pelvic, retrovesical or interlabial cystic lesions. In 16 patients, an abnormality either of the kidney or a cystic lesion was detected during the perinatal period. Another 10 patients presented clinical symptoms, including urinary incontinence in five, urinary tract infection in one, and vaginal discharge in four. Based on clinical features and imaging findings, the patients were divided into four groups: those with Gartner's duct cyst (Group 1, n=9); those with uterovaginal duplication with obstructed hemivagina (Herlyn-Werner-Wunderlich syndrome [HWW]; Group 2, n=3); those with both Gartner's duct cyst and HWW syndrome (Group 3, n=3); and those without definitive diagnosis (Group 4, n=11). In Group 1, leakage completely stopped after nephrectomy in three patients, whereas six patients continued to be incontinent despite the removal of dysgenetic kidneys. In Group 2, after the excision of a vaginal septum, no patient presented urinary incontinence. In patients in Group 3, both the mesonephric remnant and mullerian structures were confirmed on imaging or through endoscopy. Because of the high coincidence of genital and renal anomalies, it is recommended that genital systems in female patients with renal anomalies associated with cystic lesions behind the lower urinary tract be investigated. The best imaging modality to use remains under scrutiny. It is important to follow the patients until the age of puberty. The importance of a long-term follow-up in these patients needs to be emphasized. (author)

    Sarah Dotters-Katz

    2013-09-01

    Full Text Available Thalidomide is a well-known teratogen, which is experiencing resurgence as new uses are identified. Exposure is classically associated with limb deformities, such as: dysmelia, phocomelia, preaxial hypoplasia and polydactyly, in addition to visceral anomalies that have been documented as well. We report a case of a 38 year-old nulligravid female, who was previously evaluated for primary amenorrhea, and given the presumptive false diagnosis of an imperforate hymen. On magnetic resonance imaging (MRI exam, she was noted to have uterovaginal agenesis. The implications of thalidomide on women’s health extend beyond external birth defects. Although, most commonly associated with limb deformities, there may also be gynecologic implications of in utero exposure. As this medication is increasingly used for various medical conditions, obstetricians/gynecologists need to remain aware of this potential mullerian teratogenic effect.

    2016-11-30

    Agenesis of corpus callosum is a relatively frequent congenital cerebral malformation including dysplasia, total or partial absence of corpus callosum. The agenesis of corpus callosum can be occured in isolated form without accompanying somatic or central nervous system abnormalities and it can be associated with other central nervus system malformations. The behavioral and cognitive outcome is more favorable for patients with isolated agenesis of corpus callous than syndromic form of corpus callosum. The aim of this study is to review recent research on behavioral and social-cognitive functions in individuals with agenesis of corpus callosum. Developmental delay is common especially in higher-order cognitive and social functions. An internet database search was performed to identify publications on the subject. Fifty-five publications in English corresponded to the criteria. These studies reported deficits in language, social cognition and emotions in individuals with agenesis of corpus callosum which is known as primary corpus callous syndrome. The results indicate that individuals with agenesis of corpus callosum have deficiency in social-cognitive domain (recognition of emotions, weakness in paralinguistic aspects of language and mentalizing abilities). The impaired social cognition can be manifested in behavioral problems like autism and attention deficit hyperactivity disorder.

    The relationship between serum uric acid and arterial stiffness or blood pressure is not clear. The serum uric acid level and its association with cardiovascular risk is not well known in patients with reduced renal mass. We aimed to investigate the relation between serum uric acid levels and arterial stiffness and also blood pressure in patients with congenital renal agenesis and/or hypoplasia. In this single center, cross-sectional study, a total of 55 patients (39 (% 70.9) with unilateral small kidney and 16 (%29.1) with renal agenesis) were included. The median age was 35 (21-50) years. The study population was divided into tertiles of serum uric acid (according to 2.40-3.96, 3.97-5.10, and 5.11-9.80 mg/dl cut-off values of serum uric acid levels). Official and 24-h ambulatory non-invasive blood pressures of all patients were measured. The arterial stiffness was assessed by pulse wave velocity (PWV). PWV values were increased from first to third tertile (5.5 ± 0.6, 5.7 ± 0.8, 6.1 ± 0.7, respectively), but this gradual increase between tertiles did not reach significance. Linear regression analyses showed a positive correlation between serum uric acid levels and PWV (β = 0.40, p = 0.010), but no correlation was found between uric acid and daytime systolic blood pressure (β = 0.24, p = 0.345). In congenital renal agenesis/hypoplasia, the serum uric acid level was positively correlated with arterial stiffness, but there was no correlation with blood pressure.

    Agenesis of the internal carotid artery (ICA) is a rare congenital abnormality, sporadically reported to be associated with a combined congenital hypopituitarism. Nevertheless, only a few cases have been extensively described, and none of these have been characterized by an isolated growth hormone (GH) deficiency. Here, we describe a 17-year old boy referred to our hospital for fatigue, decreased muscle strength and severe headache reported after the cessation of rhGH treatment for a GH deficiency diagnosed at the age of 2 years and 3 months. Magnetic resonance imaging (MRI) showed an adenohypophyseal hypoplasia with a lack of posterior pituitary hyperintensity, whereas MRI angiography indicated the absence of a normal flow void in the left ICA. Endocrinological tests confirmed the GH deficiency (GH peak after growth-hormone-releasing hormone (GHRH) + arginine: 2.42 ng/mL) with a very low IGF-I value (31 ng/mL) and normal function of other pituitary axes. To the best of our knowledge this is the first confirmed case of an isolated GH deficiency in a patient with ICA agenesis. The presence of an isolated pituitary deficit is unlike to be considered only as an effect of hemodynamic mechanism, suggesting a role for genetic factor(s) as a common cause of these two rare birth defects. Further studies could clarify this issue and the underlying mechanisms to better understand the etiopathogenetic characteristics of this disorder.

    A 29-year-old woman with a history of hypothyroidism since early childhood developed hypopituitarism. CT and MRI revealed anterior pituitary hypoplasia, an ectopic posterior lobe, a Chiari I malformation and agenesis of the right internal carotid artery with a trans-sellar anastomosis. This constellation of findings constitutes a previously unreported association in congenital hypopituitarism of late onset. The usefulness of imaging modalities and the pathogenic implications are also discussed. (orig.)

    2009-09-01

    We present a case of a patient with Uterus bicornis bicollis, imperforate hemivagina and ipsilateral renal agenesis. This group of congenital malformations is often asymptomatic until puberty, when it presents as cyclic dysmenorrhoea, leucorrhoea or a pelvic mass. Magnetic resonance imaging is becoming the preferred modality for delineation of uterine malformations. When congenital abnormalities of the reproductive tract are encountered, a search should also be made for renal anomalies. Patients with Uterus bicornis bicollis and unilateral imperforate vagina are often seen with pain severe enough to mimic an acute abdomen. It is important to keep this unusual congenital malformation in mind in the differential diagnosis of vaginal discharge, pelvic mass and/or abdominopelvic pain in young women so as to avoid inappropriate surgical procedures.

    Accompanied consultations are often reported as difficult by occupational physicians but have not been studied in the occupational health setting. To collect information about accompanied consultations and the impact of the companion on the consultation. We collected data on all accompanied consultations by two occupational physicians working in a private sector occupational health service over the course of 16 months. Accompanied consultations were matched to non-accompanied consultations for comparison. We collected data on 108 accompanied consultations.

    Klippel-Feil syndrome (KFS), a triad of short neck, limitation of neck movement and low posterior hairline, is characterized by the presence of congenitally fused cervical vertebrae and is often associated with multiple congenital anomalies. A 35-year-old male was referred for evaluation of an 'opaque hemithorax'. This led to a diagnosis of KFS, agenesis of left lung and gall bladder. The patient had history of wheezing dyspnea with nasal symptoms, which were diagnosed as asthma and allergic rhinitis. A high index of suspicion is required to recognize such a patient, and efforts should be made to seek other congenital anomalies. (author)

  5. An Unusual Case of Recurrent Pyocolpos Following Midtrimester Miscarriage Revealed as Obstructed Hemivagina with Ipsilateral Renal Agenesis (OHVIRA Syndrome

    Full Text Available Obstructed hemivagina with ipsilateral renal agenesis (OHVIRA Syndrome is a rare congenital anomaly. It mostly presents with severe dysmenorrhea and a palpable mass due to unilateral hematocolpos. Sometime it presents in unusual way with prolonged vaginal bleeding and profuse vaginal discharge. Here we report case of an 18 years old married female with OHVIRA syndrome presenting late with symptoms of recurrent pyocolpos following dilatation and evacuation for midtrimester miscarriage that was diagnosed on the basis of MRI and managed by vaginal septotomy.

  6. Comparison between UBV- and RGU-photometrically determined density functions for the photometric disk and halo and between the corresponding mean isodensity behaviour in the halo close to the galactic north-pole (SA 57)

    Science.gov (United States)

    Fenkart, R.; Esin-Yilmaz, F.

    1985-10-01

    SA 57, RG U-photometrically treated by Fenkart (1967), is the third field of the Basle Halo Program (BHP) we investigate by applying the RG U-methods for the separation of the (photometric) populations disk and halo and for the determination of their space densities analogously in UBV in order to compare the results independently obtained in both systems. Figures 1 and 2 give the V- and G-fractioned two-colour diagrams of the same 1179 stars treated in UBV and RG U, respectively. On their basis, the logarithmic space density functions of both populations have been calculated for the overall (3m to 8m ) and for the 1m -intervals absolute magnitudes M(V) and M(G). They are tabulated in tables II and III and plotted in figures 3 and 4, respectively (a : disk, b : halo). The overall density functions for the disk and for the halo are compared between the systems in figures Sa and b, respectively. The mean misidentification-rate per system (MMRS) is 7.3 %, lying between the ones for SA 54(9.2 %) and for SA 82(4.5 %) (Fenkart and Esin-Yilmaz, 1983 and 1984, respectively) and close to the mean for all three investigations (7.0 ± 2.4 %) The direction to SA 57 lies almost in the middle of the sector of the northern galactic meridian which is limited by the directions to SA 54 and to SA 82. Our results permit, together with the ones obtained in these limiting directions, the comparison of the mean isodensity-patterns obtained in both systems within this sector. They are completely parallel and blend in perfectly with the mean (RG U-) isodensity-pattern of the - partly overlapping - sector between SA 51 and SA 57 obtained by Fenkart and Karaall (1984) (Fig. 6). The appendices describe shortly the involved methods (A) and refer to related work by other authors in the direction to the galactic north-pole (B).

    2012-01-01

    Background The purpose of this study was to associate smile esthetic judgment with dentofacial attributes of patients with unilateral and bilateral agenesis of maxillary lateral incisors treated with recontouring of canines or implants and patients with no agenesis (control). Material and methods Forty-six participants were divided into two groups: those treated with recontouring (N = 26) and those treated with implants (N = 20). The participants in the control group (N = 22) were selected among dentistry students at the State University of Maringá, Brazil. Photographs of posed smiles (17 cm × 10 cm) were evaluated with a 100-mm Visual Analog Scale. Smile attractiveness was judged by two groups: laypersons and dentists (N = 20 in each group). Judgment was classified into Unpleasant and Pleasant. Measurements of 11 smile attributes were done with ImageTool Version 3.0. These measurements were correlated with the type of judgment using the Pearson correlation coefficient. Results The two groups of evaluators showed no rating difference (analysis of variance, P = 0.64), thus they were placed into a single group. No significant correlation was found between esthetic judgment and six smile attributes (incisor exposure, interlabial gap, width 3 to 3, smile index, right buccal corridor, and buccal corridor ratio). The control group showed more correlations with the unpleasant judgment type than the other groups. Conclusion Some correlations between smile attributes and esthetic judgment were found, but other features of smiles not evaluated in this study may interfere in smile attractiveness. PMID:23674925

  8. Discordant tooth agenesis and peg-shaped in a pair of monozygotic twins: Clinical and molecular study

    2013-01-01

    Full Text Available The present report aimed to study an uncommon case of a pair of twins that presented a discordant dental phenotype. Family investigation, clinical, radiographic examination and molecular analysis were performed in both girls. Molecular analysis confirmed the monozygosity by deoxyribonucleic acid chip technology. One twin presented tooth agenesis in left upper lateral incisor and peg-shaped on the contra lateral side while the other twin had no dental alterations. The dental casts study employed digital caliper to compare morphological dimensions and showed alteration only in peg-shaped tooth. In conclusion, this study provide support that one or more mutated gene could cause discordances in dental phenotype in these monozygotic twins.

    Mitochondrial aminoacyl tRNA synthetases are essential for organelle protein synthesis. Genetic defects affecting the function of these enzymes may cause pediatric mitochondrial disease. Here, we report on a child with fatal neonatal lactic acidosis and recurrent hypoglycemia caused by mutations in EARS2, encoding mitochondrial glutamyl-tRNA synthetase 2. Brain ultrasound revealed agenesis of corpus callosum. Studies on patient-derived skin fibroblasts showed severely decreased EARS2 protein levels, elevated reactive oxygen species (ROS) production, and altered mitochondrial morphology. Our report further illustrates the clinical spectrum of the severe neonatal-onset form of EARS2 mutations. Moreover, in this case the live-cell parameters appeared to be more sensitive to mitochondrial dysfunction compared to standard diagnostics, which indicates the potential relevance of fibroblast studies in children with mitochondrial diseases.

  11. Butterfly adrenal gland with maldevelopment of the mesonephric duct: A rare association in an adult patient

    Directory of Open Access Journals (Sweden)

    Nur Hursoy, MD

    2018-04-01

    Full Text Available Adrenal gland disorders can be asymptomatic and detected incidentally via imaging techniques such as ultrasound, computed tomography (CT, positron emission tomography, and magnetic resonance imaging. Fusion anomaly is a condition that can be attributed to errors in the developmental process and may be detected via these imaging modalities. We present a case of butterfly adrenal gland in a 61-year-old man with CT and magnetic resonance images. In our patient, this anomaly is also accompanied by unilateral renal agenesis and a diaphragmatic defect. Positron emission tomography-CT, contrast-enhanced CT, and magnetic resonance images are presented. To the best of our knowledge, this is the second case in which coexistence of unilateral renal agenesis and butterfly adrenal gland anomaly in an adult patient has been documented.

    2017-01-01

    Full Text Available Pulmonary artery agenesis combined with tetralogy of Fallot is the most rarely seen congenital heart disease. Children with this anomaly are an especially problematic category of patients undergoing staged surgical repair. The postoperative period quite often is complicated with shunt thrombosis while a redo open surgery is associated with a very high risk; therefore, endovascular repair is a preferred procedure. We describe a case of right ventricular outflow tract stenting in a 8 month old girl with tetralogy of Fallot and right pulmonary artery agenesis. The patient was admitted at 3 month after performing of a left-sided modified Blalock-Taussig shunt with severe signs of heart failure and desaturation caused by shunt thrombosis. Assessments performed at 2 months after stenting of the outflow tract demonstrated good oxygen saturation in arterial blood (80% and above and improvement of heart failure symptoms to NYHA II class.

  15. MURCS Association with Partial Duplication of the Distal Long Chromosome 5 and Unilateral Ovarian Agenesis

    Directory of Open Access Journals (Sweden)

    Anna Dabkowska-Huc

    2013-01-01

    Full Text Available A combination of the congenital abnormalities, Müllerian duct aplasia, renal aplasia, and cervicothoracic somite dysplasia, is defined as the MURCS association. Various genetic defects have been described in the MURCS association so far, yet the unambiguous molecular basis of these disorders has not been established. We report the case of an 18-year-old woman who presented with primary amenorrhea, right kidney, Arnold-Chiari malformation, and Klippel-Feil syndrome. In addition, the patient showed the following unusual features: right ovarian and Skenes gland agenesis, cubitus valgus with hyperextension and decreased range of motion at elbows, and facial changes. Moreover, the performed DNA analysis showed interstitial duplication in chromosome 5 (5q35.1. In the duplicated region, there are genes whose function is not well known. It is thought that they have an influence on the early stages of development and their joining in the later period can lead to neoplastic disorders, especially leukemias.

  16. Proverb comprehension in individuals with agenesis of the corpus callosum.

    2016-09-01

    Comprehension of non-literal language involves multiple neural systems likely involving callosal connections. We describe proverb comprehension impairments in individuals with isolated agenesis of the corpus callosum (AgCC) and normal-range general intelligence. Experiment 1 compared Gorham Proverb Test (Gorham, 1956) performance in 19 adults with AgCC and 33 neurotypical control participants of similar age, sex, and intelligence. Experiment 2 used the Proverbs subtest of the Delis-Kaplan Executive Function System (D-KEFS, 2001) to compare 19 adults with AgCC and 17 control participants with similar age, sex, and intelligence. Gorham Proverbs performance was impaired in the AgCC group for both the free-response and multiple-choice tasks. On the D-KEFS proverbs test, the AgCC group performed significantly worse on the free-response task (and all derivative scores) despite normal levels of performance on the multiple-choice task. Covarying verbal intelligence did not alter these outcomes. However, covarying a measure of non-literal language comprehension considerably reduced group differences in proverb comprehension on the Gorham test, but had little effect on the D-KEFS group differences. The difference between groups seemed to be greatest when participants had to generate their own interpretation (free response), or in the multiple choice format when the test included many proverbs that were likely to be less familiar. Taken together, the results of this study clearly show that proverb comprehension is diminished in individuals with AgCC compared to their peers. Copyright © 2016 Elsevier Inc. All rights reserved.

  17. Bilateral Deep Vein Thrombosis Associated with Inferior Vena Cava Agenesis in a Young Patient Manifesting as Low Back Pain

    Directory of Open Access Journals (Sweden)

    Felipe Langer

    2017-04-01

    Full Text Available Congenital absence of the inferior vena cava is a rare vascular anomaly, and most cases are asymptomatic. Nevertheless, patients with inferior vena cava malformations may have increased risk of deep venous thrombosis. Particularly, cases of bilateral deep venous thrombosis may arise owing to an insufficient collateral venous drainage from the lower limbs. We hereby describe a case of a previously healthy young male patient presenting with bilateral lower limb deep venous thrombosis as the initial clinical manifestation of congenital inferior vena cava agenesis. We conclude that in young patients presenting with deep venous thrombosis, especially when thrombosis occurs spontaneously, bilaterally, or recurrently, inferior vena cava anomalies should be thoroughly investigated and ruled out as appropriate.

  18. Triplets with growth failure, microcephaly, mental retardation, nail hypoplasia and corpus callosum agenesis: is it a variant of Coffin-Siris or a new syndrome?

    Kirel, B; Kural, N; Yakut, A; Adapinar, B

    2000-01-01

    We report eight-year-old triplet girls whose clinical features included microcephaly, severe mental retardation, hypoplasia of distal phalanges of both fifth and second fingers and nail hypoplasia on second fingers, dysmorphic facial features, and partial corpus callosum agenesis. During infancy, a Pavlik harness was used for congenital hip dislocation, and they had difficulty in feeding. One had been operated for patent ductus arteriosus. To our knowledge, this rare combination has not been previously reported in triplets whose clinical features closely resemble those of Coffin-Siris syndrome. The other diagnostic possibilities are also reviewed.

    Full Text Available OBJECTIVE: The purpose of this study was to evaluate the width/length ratio and the gingival zenith (GZ, by means of dental casts and digital caliper, in patients with missing maxillary lateral incisors after treatment. METHODS: The sample was composed of 52 subjects divided into 3 groups: BRG (n = 18, patients with bilateral agenesis treated with tooth re-contouring; BIG (n = 10 patients with agenesis treated with implants and CG (n = 24, control group. The data were analyzed using Shapiro-Wilk, Spearman correlation, Wilcoxon, Kruskal-Wallis, t test and ANOVA tests (p 0.05. GZ data for the right and left sides of the smile were not considered statistically different. CONCLUSION: Although no statistical difference was found in the comparison between the groups, analysis of the descriptive values showed that group BIG showed the greatest difference in values with regard to width/length ratio. Regarding gingival zenith, BRG showed the greatest difference.OBJETIVO: o propósito desse estudo foi analisar, por meio de modelos de estudo e paquímetro digital, a proporção largura/altura e o zênite gengival (ZG em pacientes com agenesia bilateral do incisivo lateral superior após o tratamento. MÉTODOS: a amostra consistiu de 52 voluntários divididos em 3 grupos: GBR (n=18, pacientes com agenesia bilateral tratados com reanatomizações dentárias; GBI (n=10, pacientes com agenesia bilateral tratados com implantes; e GC (n=24, grupo controle. Os dados foram avaliados por meio dos testes de Shapiro-Wilk, Wilcoxon, Kruskal-Wallis, teste t, ANOVA (p0,05. Os valores obtidos para os lados direito e esquerdo foram considerados iguais dentro de cada grupo. CONCLUSÃO: embora não tenham sido encontradas diferenças estatísticas na comparação entre os grupos, pela análise descritiva dos dados, o GBI foi o grupo que apresentou as medidas mais destoantes dos demais em relação à proporção largura/altura, sendo que, para o zênite gengival, a maior

    To examine providers' experiences with vaginal dilator training for patients with vaginal agenesis. Anonymous electronic survey. Members of the North American Society for Pediatric and Adolescent Gynecology. How providers learn about vaginal dilator training, common techniques, and methods used for patient training, assessment of patient readiness, common patient complaints, issues leading to early discontinuation. There were a total of 55 completed survey responses of which 31 respondents (56%) had been in practice for more than 10 years. Forty-nine were gynecologists (89%), 20 had completed a fellowship in pediatric and adolescent gynecology (36%), and 6 were reproductive endocrinologists (11%). Thirty-one respondents had first learned about vaginal dilator training through lectures (56%) whereas only 9 through mentorship and fellowship (16%). According to respondents, the most common issue leading to early discontinuation was lack of patient motivation and readiness (n = 42; 76%). The most common complication was pain or discomfort (n = 45; 82%). More than half of respondents determined dilator therapy was successful when patients reported comfortable sexual intercourse (n = 30; 55%) and 65% (n = 35) did not delineate any restrictions to initiation of sexual intercourse. Most respondents (87%) requested further vaginal dilator training at either a clinical meeting (n = 26; 47%) or with a training video (n = 22; 40%). Our study in an experienced cohort of pediatric gynecology providers highlights the need for further research and training on vaginal dilation education.

    Antidepressant discontinuation syndrome (ADS) occurs after abrupt discontinuation of an antidepressant medication. A 23-year-old man with right hippocampal agenesis demonstrated sexual crime (hypersexuality) since the age of eight and had been successfully treated with carbamazepine since the age of 13. He had required increased doses of paroxetine and carbamazepine owing to the development of an unstable affect after quitting his job. He abruptly stopped taking his medication for 3 days and his criminal behaviors re-emerged. We examined changes in brain structure and activity before and after medication cessation, using MRI and functional MRI (fMRI). The image of a girl in a swimsuit increased activity in the thalamus only after medication discontinuation. The alteration in thalamic activity might induce hypersexuality. We conclude that a primary hypersexuality had been suppressed with carbamazepine and paroxetine treatment, and the discontinuation of the medication caused the hypersexuality. © 2012 American Academy of Forensic Sciences.

    Neurodevelopmental outcome in children with agenesis of the corpus callosum (ACC) is correlated with the presence or absence of associated brain abnormalities. Indeed, neurodevelopmental outcome shows severe disabilities when the ACC is not isolated whereas in isolated forms, the neurologic development is mainly normal. Contrary to data in several published studies, the prognosis remains uncertain even in isolated forms, which may lead in France to medical termination of pregnancy. To evaluate long-term neurodevelopmental outcome in children with prenatally diagnosed isolated ACC. This is a follow-up study conducted in Normandy (France). It included a cohort of 25 children born between January 1991 and June 2016, with a prenatal diagnosis of isolated ACC and who were followed for at least two years. The average follow-up was 8±5years. ACC was complete in 17 patients (68%), partial in 5 (20%) and hypoplastic in 3 (12%). Whereas global motor development was normal in each case, normal neurodevelopmental outcome or mild disabilities occurred in 88% children and moderate/severe neuro-disabilities were present in 12% of children. Wechsler Intelligence Scale for Children-IV evaluations and Intellectual Total Quotients were within normal range, but we observed lower scores in verbal comprehension, social judgment, executive functions. A lower score in morphosyntax was observed among 52% of children with oral language disorders. Neurodevelopmental outcome was favorable in most of our patients with isolated ACC, but mild learning disabilities emerged in older children. Long-term follow-up until school age is essential to provide early diagnosis and appropriate care support. Copyright © 2017 Elsevier B.V. All rights reserved.

    2016-05-01

    Full Text Available Purpose: To report a case of ocular albinism found in a newborn infant in whom agenesis of the corpus callosum (ACC was indicated in utero. Case Report: This study involved a female newborn who was delivered after a gestational period of 41 weeks. The patient was referred to the Obstetrics Department at Takatsuki Hospital, Takatsuki City, Japan, after the indication of ACC by magnetic resonance imaging (MRI at a nearby clinic during the fetal period. At birth, the baby’s weight was 2,590 g, and ACC and ventricular enlargement were found by cranial sonography and cranial MRI. While initial ophthalmic findings noted partial loss of pigmentation of the iris and hypopigmentation of broad areas of the fundus in both eyes, nystagmus was not observed. The patient’s hair pigment was slightly diluted, and the color of her skin was slightly off-white. At 2 years after birth, obvious mental retardation was observed. With regard to other systemic findings, no apparent heart, kidney, or immune system abnormalities were found. Conclusion: Although the patient in question is presently growing without any major systemic problems, it will be necessary in the future to pay attention to any changes in systemic and ophthalmic findings.

    Children may be accompanied by various people when attending for dental treatment. Before treatment is started, there is a legal requirement that the operator obtain informed consent for the proposed procedure. In the case of minors, the person authorized to give consent (parental responsibility) is usually a parent. To ascertain if accompanying persons of children attending the Department of Paediatric Dentistry at the Eastman Dental Hospital, London were empowered to give consent for the child's dental treatment. A total of 250 accompanying persons of children attending were selected, over a 6-month period. A questionnaire was used to establish whether the accompanying person(s) were authorized to give consent. The study showed that 12% of accompanying persons had no legal authority to give consent for the child's dental treatment. Clinicians need to be aware of the status of persons accompanying children to ensure valid consent is obtained.

    2015-07-01

    The aim of this study was to determine the dental esthetic perception of the smile of patients with maxillary lateral incisor agenesis (MLIA); the perceptions were examined pre- and post-treatment. Esthetic determinations were made with regard to the gingival exposure in the patients' smile by orthodontists, general dentists, and laypersons. Three hundred eighty one people (80 orthodontists, 181 general dentists, 120 laypersons) rated the attractiveness of the smile in four cases before and after treatment, comprising two cases with unilateral MLIA and contralateral microdontia and two with bilateral MLIA. For each case, the buccal photograph was adjusted using a computer to apply standard lips to create high, medium, and low smiles. A numeric scale was used to measure the esthetic rating perceived by the judges. The resulting arithmetic means were compared using an ANOVA test, a linear trend, and a Student's t-test, applying a significance level of p esthetic perception of smiles in post-treatment cases. © 2014 by the American College of Prosthodontists.

    Unilateral pulmonary artery hypoplasia or agenesis without congenital cardiovascular anomalies is rare in adults. We report a case of a 36-year-old man with isolated left unilateral pulmonary artery hypoplasia with recurrent hemoptysis. On computed tomography (CT), the left pulmonary artery showed hypoplasia with multiple collateral vessels seen in the mediastinum and the left hemithorax. Also, parenchymal bands and peripheral linear opacities were seen in the affected lung, which were probably due to chronic infarction induced by unilateral pulmonary artery hypoplasia. There are only a few reports focusing on the radiologic findings in the pulmonary parenchyma induced by unilateral pulmonary artery hypoplasia, such as parenchymal bands and peripheral linear opacities. Therefore we report this case, which focused on the CT findings in the pulmonary parenchyma due to isolated unilateral pulmonary artery hypoplasia.

    Full Text Available O planejamento ortodôntico de pacientes com agenesia de incisivos laterais envolve considerações estéticas e funcionais de grande relevância para um resultado clínico satisfatório. Tanto o fechamento dos espaços correspondentes aos dentes ausentes quanto sua abertura ou manutenção oferecem vantagens e desvantagens que devem ser avaliadas de acordo com as características individuais do paciente. Fatores importantes que influenciam o planejamento são o padrão esquelético, o tipo de má oclusão e a coloração e forma dos caninos, dentre outros. Neste artigo, teve-se como objetivo relatar o tratamento de uma paciente com má oclusão Classe I de Angle, agenesia de incisivos laterais, sobressaliência e sobremordida diminuídas, tendência à mordida aberta e mordida cruzada.A abordagem clínica foi realizada com expansão maxilar, seguida de fechamento dos espaços, com auxílio de ancoragem esquelética extrabucal.

    To report a case of pigmentary glaucoma (PG) accompanied by Usher syndrome. Case report. The results were presented after standard ocular examination, visual field test, anterior segment and fundus photography, electroretinography, and otolaryngology consultation were conducted. Typical retinitis pigmentosa, flat electroretinography, congenital sensorineural hearing loss, high intraocular pressure, Krukenberg spindle, iris concavity, radial iris transillumination defect, severe pigment deposition on the trabecular meshwork, and glaucomatous optic nerve damage were indicative of PG accompanied by Usher syndrome. In some rare cases, PG may coexist with Usher syndrome. Common findings of Usher syndrome, including night blindness, impaired vision, visual field defects, and retinal changes may distract the clinician from considering the diagnosis of glaucoma. Such association should be borne in mind to make a timely diagnosis and treatment possible.

    Full Text Available We describe herein a case of unilateral pulmonary agenesis (PA with oesophageal atresia (EA/tracheoesophageal fistula (TEF that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4 th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up.

    The purpose of this study was to investigate the methods of clinical accompaniment used by clinical facilitators in practice. The findings of the study also reflected facilitators' perceptions regarding critical thinking and the facilitation thereof. A quantitative research design was used. A literature study was conducted to identify the methods of accompaniment that facilitate critical thinking. Data was collected by means of a questionnaire developed for that purpose. Making a content-related validity judgment, and involving seven clinical facilitators in an academic institution, ensured the validity of the questionnaire. The results of the study indicated that various clinical methods of accompaniment were used. To a large extent, these methods correlated with those discussed in the literature review. The researcher further concluded that the concepts 'critical thinking' and 'facilitation' were not interpreted correctly by the respondents, and would therefore not be implemented in a proper manner in nursing practice. Furthermore, it seemed evident that tutor-driven learning realised more often than student-driven learning. In this regard, the requirement of outcomes-based education was not satisfied. The researcher is therefore of the opinion that a practical programme for the development of critical thinking skills during clinical accompaniment must be developed within the framework of outcomes-based education.

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    The authors report 2 cases of gangliogliomas of the sellar region, one of which was associated with chromophobe adenoma. Case 1. A 14-year-old female was admitted for a visual disturbance. Neurological examination showed bitemporal hemianopsia and secondary optic atrophy. CT scan showed an isodense mass in the suprasellar region, with homogneous enhancement by contrast medium and an accompanying low-density area in the left thalamus adjacent to the enhanced tumor mass. The histological diagnosis of the surgical specimen was ganglioglioma. Case 2. A 52-year-old female was admitted under the diagnosis of pituitary adenoma. Neurological examination showed bitemporal hemianopsia and signs of acromegaly. Plain skull X-ray film showed sellar ballooning and decalcification of the posterior clinoid process. The tumor resected in the first operation was histologically diagnosed as chromophobe adenoma mixed with ganglioglioma. In the follow-up, she showed signs and symptoms of a recurrent tumor, which was revealed to be ganglioglioma without any recurrence of chromophobe adenoma in the subsequent operations. The CT scan before the second operation showed an isodense supraand intrasellar mass with marked enhancement. Ganglioglioma is a rare, benign, nerve-cell tumor, mostly occurring in childhood and adolescence. The CT findings, together with the clinical history, the age of the patient, and the tumor location, may suggest the tentative preoperative diagnosis of ganglioglioma.

  7. Problems with radiation protection concerning volunteers accompanying radiological patients

    2008-01-01

    Full text: The purpose of this work is to point out, within the framework of the Radiation Protection guidelines, the irregular situation of the 'volunteer' or 'accompanying person' who accompanies anyone requiring medical treatment with ionising radiation, as well as to suggest a possible justification for such role. It should be noted that most of these persons are subject to ionising radiation without knowing anything about the effects that it could cause on them, so that their condition could be hardly considered as 'voluntary'. There are several circumstances under which the presence of accompanying persons is required, being different among them. Several examples could be mentioned such as: those who are accompanying a direct relative (family bonds), those who are acting in service during their normal work (social workers, policemen) and even those who are forced by unusual under an accidental situation. The qualitative classification that radiological protection established in society concerning radiation risks for people in general enables to set mechanisms of justification, optimisation and dose limitation for each category, being perfectly identified which of them each person belongs to. But the figure of 'accompanying person' has been excluded from such characterisation. They are subject to radiation exposure without knowing it, or without having any information concerning the potential risks. For them, no balance between the net benefit of an adequate medical treatment versus potential health detriment may be applied as for the case of a patient. Thus, their exposure could be not justified. It is not the purpose of this work to question radiological medicine or its practices, but to clarify certain aspects involving members of the public in general, patients and members of the radiological community, as well as to propose lines of action concerning this subject. We conclude that it is not the volunteer who should decide about medical actions, a role

    Full Text Available OBJECTIVE: The purpose was to obtain information about the relation between agenesis and shape anomaly of maxillary lateral incisors and canine impaction. METHODS: Seventy-three patients with canine impaction and 73 control patients, without canine impaction, were evaluated. The mesiodistal distances of the maxillary lateral incisors adjacent to the impacted canines and the correspondent mandibular lateral incisors were measured. The adjacent lateral incisors were classified in: 1 - absent, 2 - small, 3 - peg-shaped, 4 - standard. RESULTS: The results showed that among the patients with impacted canines, there were 21 anomalous teeth (small and peg-shaped and among the control patients there were only three small and peg-shaped teeth, with a statistically significant difference (p = 0.001. No patients were found with impacted canines and absent lateral incisors. CONCLUSION: It was concluded that in patients with anomalous lateral incisors (small and peg-shaped there is a probability to present impacted canines and this must be considered.OBJETIVO: o objetivo foi obter informação sobre a relação existente entre a agenesia e/ou anomalia de forma de incisivos laterais superiores e impacção de caninos.

    Otolithic vertigo is sometimes accompanied by hearing loss. Otolithic vertigo accompanied by hearing loss seems to be caused by sacculocochlear endolymphatic hydrops. To clarify the lesion site and pathophysiology of otolithic vertigo (OV) accompanied by hearing loss. The clinical records of four patients (two men and two women) that had been diagnosed with OV accompanied by hearing loss according to pre-determined diagnostic criteria were reviewed. The patients' main symptoms involved a sensation of movement in the pitch plane. All of the patients had low frequency-dominant hearing loss and either exhibited decreased cervical vestibular evoked myogenic potentials (cVEMP) or did not produce cVEMP. Two patients produced normal ocular VEMP (oVEMP). Caloric tests obtained normal results in all patients.

    The goal of this study was to explore and describe the experiences of students with regard to value-sensitive clinical accompaniment in the community nursing environment. An exploratory, descriptive and contextual design was used. Interactions between community nurses and students during clinical accompaniment were explored for value sensitivity by means of video recordings,participant observation and focus group interviews. Data were collected by means of video recordings, participant observation and focus group interviews. The data were analysed and coded by the researcher and the external coder, using an inductive descriptive method to identify important segments of the regularity of behaviour. The focus group interviews were transcribed, analysed and coded by the researcher and the external coder, using Tesch’s steps of analysis (Creswell 1994:155–156.Lincoln and Guba’s criteria (1985:290 for trustworthiness were applied to the study. The general findings indicate that clinical accompaniment in community nursing is not value sensitive and, as a result, guidelines for value-sensitive clinical accompaniment need to be developed for undergraduate students in the community nursing environment. The following values (values for which guidelines need to be developed were identified: respect during clinical accompaniment,value-sensitive communication and sensitivity to the quality of clinical accompaniment.

    2013-01-01

    Constitutional mismatch repair deficiency (CMMR-D) syndrome is a rare inherited childhood cancer predisposition caused by biallelic germline mutations in one of the four mismatch repair (MMR)-genes, MLH1, MSH2, MSH6 or PMS2. Owing to a wide tumor spectrum, the lack of specific clinical features and the overlap with other cancer predisposing syndromes, diagnosis of CMMR-D is often delayed in pediatric cancer patients. Here, we report of three new CMMR-D patients all of whom developed more than one malignancy. The common finding in these three patients is agenesis of the corpus callosum (ACC). Gray matter heterotopia is present in two patients. One of the 57 previously reported CMMR-D patients with brain tumors (therefore all likely had cerebral imaging) also had ACC. With the present report the prevalence of cerebral malformations is at least 4/60 (6.6%). This number is well above the population birth prevalence of 0.09-0.36 live births with these cerebral malformations, suggesting that ACC and heterotopia are features of CMMR-D. Therefore, the presence of cerebral malformations in pediatric cancer patients should alert to the possible diagnosis of CMMR-D. ACC and gray matter heterotopia are the first congenital malformations described to occur at higher frequency in CMMR-D patients than in the general population. Further systematic evaluations of CMMR-D patients are needed to identify possible other malformations associated with this syndrome.

  15. Real-time implementation of an interactive jazz accompaniment system

    Science.gov (United States)

    Deshpande, Nikhil

    Modern computational algorithms and digital signal processing (DSP) are able to combine with human performers without forced or predetermined structure in order to create dynamic and real-time accompaniment systems. With modern computing power and intelligent algorithm layout and design, it is possible to achieve more detailed auditory analysis of live music. Using this information, computer code can follow and predict how a human's musical performance evolves, and use this to react in a musical manner. This project builds a real-time accompaniment system to perform together with live musicians, with a focus on live jazz performance and improvisation. The system utilizes a new polyphonic pitch detector and embeds it in an Ableton Live system - combined with Max for Live - to perform elements of audio analysis, generation, and triggering. The system also relies on tension curves and information rate calculations from the Creative Artificially Intuitive and Reasoning Agent (CAIRA) system to help understand and predict human improvisation. These metrics are vital to the core system and allow for extrapolated audio analysis. The system is able to react dynamically to a human performer, and can successfully accompany the human as an entire rhythm section.

    A 62-year-old man was referred to us after unsuccessful treatment of bilateral weakness in his upper and lower extremities with paresthesia in both lower extremities. Computed tomography (CT) revealed soft tissue masses in the left kidney along the capsule and paraaortic region that were of relatively low attenuation with accompanying granular calcifications. Pathological diagnosis of the biopsy specimen was extramedullary plasmacytoma accompanied by extramedullary hematopoiesis and amyloid deposition. Although the CT findings correlated well with the pathological results, the case was extremely atypical for extramedullary plasmacytoma in respect to location and the accompaniment with extramedullary hematopoiesis.

    Peroneal tendon displacement (subluxation or dislocation) accompanying an intra-articular calcaneal fracture is often undetected and under-treated. The goals of this study were to determine (1) the prevalence of peroneal tendon displacement accompanying intra-articular calcaneal fractures, (2) the association of tendon displacement with fracture classifications, (3) the association of tendon displacement with heel width, and (4) the rate of missed diagnosis of the tendon displacement on radiographs and computed tomography (CT) scans and the resulting treatment rate. A retrospective radiographic review of all calcaneal fractures presenting at three institutions from June 30, 2006, to June 30, 2011, was performed. CT imaging of 421 intra-articular calcaneal fractures involving the posterior facet was available for review. The prevalence of peroneal tendon displacement was noted and its associations with fracture classification and heel width were evaluated. Peroneal tendon displacement was identified in 118 (28.0%) of the 421 calcaneal fracture cases. The presence of tendon displacement was significantly associated with joint-depression fractures compared with tongue-type fractures (p displacement had been identified in the radiology reports. Although sixty-five (55.1%) of the fractures with tendon displacement had been treated with internal fixation, the tendon displacement was treated surgically in only seven (10.8%) of these cases. Analysis of CT images showed a 28% prevalence of peroneal tendon displacement accompanying intra-articular calcaneal fractures. Surgeons and radiologists are encouraged to consider this association.

    Diphallus (penile duplication) is very rare and seen once every 5.5 million births. It can be isolated, but is usually accompanied by other congenital anomalies. Previous studies have reported many concurrent anomalies, such as bladder extrophy, cloacal extrophy, duplicated bladder, scrotal abnormalities, hypospadias, separated symphysis pubis, intestinal anomalies and imperforate anus; no penile duplication case accompanied by omphalocele has been reported. We present the surgical management of a patient with multiple anomalies, including complete penile duplication, hypo-gastric omphalocele and extrophic rectal duplication.

    We report a case of Terrien's marginal degeneration (TMD) with a unilaterally typical narrow band of peripheral corneal stroma thinning, accompanied by the presence of an unusual network of opacities diffusing throughout the anterior stroma layers. A 43-year-old woman presented with superior nasal peripheral corneal thinning and an unusual network of polygonal stromal opacities in the anterior corneal stroma of the right eye. Latticed corneal changes were unusually extensive and distributed diffusely in the stroma. No abnormalities were found in the corneal epithelium and in the basal epithelial cells. No noticeable changes were found in the left eye. Because of a progressively worse ocular irritation of the right eye, a diagnosis of TMD was made for this patient. This case of TMD accompanied by keratopathy was unusual. The branching stromal lattice pattern of the corneal opacities was difficult to distinguish from lattice corneal dystrophy. In this case, the polygonal stromal opacities were located in the anterior corneal stroma and therefore were distinguished from a similar manifestation in posterior crocodile shagreen.

    Full Text Available It is needed a foundation and some orientations to act in loss and grief situations with adults with intellectual disabilities. In this article, through a relevant literature review, we based the educational accompaniment as a pedagogic methodology of support with three principal elements: a The conception of grief from its formative potential, b The prevention of disorders associated to grief complications, c The pedagogic intervention preferably from the tutorship or from the actuation of educators or professionals near to intellectual disabilities people. The educational accompaniment model is a proposal that can be placed on humanist models of grief since it considers both the characteristics of the grieving process and the formative possibilities of its elaboration. The article’s conclusions present some of the benefits of the educational accompaniment for adults with intellectual disabilities.

    Silverman, Michael J; Schwartzberg, Edward T

    2014-01-01

    Information is often paired with music in an attempt to facilitate recall and enhance learning. However, there is a lack of basic research investigating how music carrying information might facilitate recall and subsequent learning. The purpose of the current study was to determine the effects of voice timbre and accompaniment on working memory as measured by recall performance on a sequential digit recall task. Specific research questions were as follows: (a) How might female and male voice timbres affect serial recall? (b) How might piano, guitar, and no accompaniment affect serial recall? (c) Do music majors have enhanced recall accuracy when compared to nonmusic majors? The recall of information paired with six different melodies was tested on 60 university students. Melodies were composed and recorded using female and male voices with three levels of accompaniment: guitar, piano, and no accompaniment. Participants had more accurate recall during the male voice and piano and no accompaniment conditions and least accurate recall during the female voice and guitar accompaniment conditions. As participants had most accurate recall during the male voice and with piano or no accompaniment, clinicians are encouraged to consider using no accompaniment or piano accompaniment when initially teaching social and academic information paired with music for later recall. When possible, vocal timbre (i.e., the potential benefit of male voicing) should also be considered. Implications for clinical practice, limitations of the study, and suggestions for future research are provided. © the American Music Therapy Association 2014. All rights reserved.

    Rectal duplication (RD) cysts are rare congenital anomalies that can be diagnosed with the presence of another opening in the perineum. They seldom accompany anorectal malformations (ARM). Two cases of RD accompanying ARM at opposite ends of the phenotypic spectrum, are described. A 3-month-old baby and a 2-year-old girl with ARM were scheduled for posterior sagittal anorectoplasty. The infant had an orifice at the anal dimple and the other had an orifice at the vestibulum posterior to the rectovestibular fistula. The infant presented with no other anomalies whereas the older one presented with an unusual coexistence of caudal duplication and caudal regression syndromes. Perioperatively both orifices were found to be related to retrorectal cysts, and were excised. Clinicians should always be alert when dealing with complex malformations. Because these malformations have variable anatomical and clinical presentations, they can represent a diagnostic and therapeutic challenge. © 2013 The Authors.

      The aim of this study was to radiographically investigate the prevalence of dental anomalies outside the cleft area in a group of Brazilian patients with nonsyndromic cleft lip and/or palate (NSCL/P).   A retrospective analysis of 207 panoramic radiographs of patients with NSCL/P aged 12 to 45 years without history of tooth extraction and orthodontic treatment was performed.   Dental anomalies were found in 75.4% of the patients, and tooth agenesis (29.2%) and supernumerary tooth (2.6%) were the most common anomalies. The risk of agenesis was higher among the individuals with cleft palate (CP) compared with individuals with cleft lip (CL) and cleft lip and palate (CLP) (agenesis: CP versus CL: odds ratio 6.27, 95% confidence interval 2.21-17.8, P = .0003; CP versus CLP: odds ratio 2.94; 95% confidence interval 1.27-6.81, P = .01). The frequency of dental agenesis was higher in patients with unilateral complete CLP (agenesis: P dental agenesis (P dental anomalies in patients with NSCL/P was higher than that reported in overall population. This study found preferential associations between dental anomalies and specific extensions of NSCL/P, suggesting that dental agenesis and ectopic tooth may be part of oral cleft subphenotypes.

    Full Text Available ORFEO, the PLEIADES Accompaniment Program, was set up by CNES, the French Space Agency, to prepare, accompany and promote the use and the exploitation of the images acquired by this Very High Resolution optical sensor. It was initiated in 2004 and will last until the end of the first year of the satellite life (launched in December 2011 . The Thematic part of the ORFEO accompaniment program covers a large range of applications, and aims at specifying and validating products and services required by users. An in-depth work of user needs assessments in eight thematic domains (sea and coastline, risks and humanitarian aid, cartography and urban planning, geophysical hazards, hydrology, forestry, agriculture and defence has given rise to a large number of feasibility studies from 2006 to 2011. The Methodological Part of the ORFEO accompaniment program aims at preparing the use and exploitation of these submetric images. CNES decided to develop Orfeo Toolbox (OTB, an open source library capitalising the methodological know-how as a set of image processing and algorithmic components. Among other, OTB provides a number of heavily documented image processing functionalities such as filtering, feature extraction, segmentation, classification, change detection, 3D extraction, GIS links,.... As a conclusion to the ORFEO program, the PLEIADES Users Thematic Commissioning (UTC started three months after the satellite launch and will last until mid 2013. It covers a large number of specific interest ORFEO sites, on which PLEIADES images are being intensively acquired and processed.

    2013-01-01

    Full Text Available Pathogenetically, prescription of local action drugs containing a wide spectrum antiseptic is reasonable for the upper respiratory tract diseases accompanied by throat irritation and pain. It should be noted that such drugs are very popular among parents; however, most of these drugs may have a range of side effects, which considerably complicate their use in children. That is why the right choice of local action drugs for the acute inflammatory diseases accompanied by throat irritation and pain is a guarantee of treatment efficacy and high compliance. This article examines pharmacological qualities of an antiseptic-containing local action drug permitted to use in children over 4 years of age.

    2009-01-01

    This study was designed to assess superparamagnetic iron oxide (SPIO)-enhanced MRI findings of well-differentiated hepatocellular carcinomas (HCCs) correlated with their multidetector-row CT (MDCT) findings. Seventy-two patients with 84 pathologically proven well-differentiated HCCs underwent triple-phase MDCT and SPIO-enhanced MRI at a magnetic field strength of 1.5 Tesla (n = 49) and 3.0 Tesla (n = 23). Two radiologists in consensus retrospectively reviewed the CT and MR images for attenuation value and the signal intensity of each tumor. The proportion of hyperintense HCCs as depicted on SPIO-enhanced T2- or T2*-weighted images were compared in terms of tumor size ( 1 cm), five CT attenuation patterns based on arterial and equilibrium phases and magnetic field strength, by the use of univariate and multivariate analyses. Seventy-eight (93%) and 71 (85%) HCCs were identified by CT and on SPIO-enhanced T2- and T2*-weighted images, respectively. For the CT attenuation pattern, one (14%) of seven isodense-isodense, four (67%) of six hypodense- hypodense, four (80%) of five isodense-hypodense, 14 (88%) of 16 hyperdense- isodense and 48 (96%) of 50 hyperdense-hypodense HCCs were hyperintense (Cochran-Armitage test for trend, p 0.05). Most well-differentiated HCCs show hyperintensity on SPIOenhanced MRI, although the lesions show various CT attenuation patterns. The CT attenuation pattern is the main factor that affects the proportion of hyperintense well-differentiated HCCs as depicted on SPIO-enhanced MRI

    Full Text Available Abstract: Both X-linked hypohidrotic ectodermal dysplasia (XLHED and non-syndromic tooth agenesis (NSTA result in symptoms of congenital tooth loss. This study investigated genetic causes in two families with XLHED and four families with NSTA. We screened for mutations of WNT10A, EDA, EDAR, EDARADD, PAX9, MSX1, AXIN2, LRP6, and WNT10B through Sanger sequencing. Whole exome sequencing was performed for the proband of NSTA Family 4. Novel mutation c.1051G>T (p.Val351Phe and the known mutation c.467G>A (p.Arg156His of Ectodysplasin A (EDA were identified in families with XLHED. Novel EDA receptor (EDAR mutation c.73C>T (p.Arg25*, known EDA mutation c.491A>C (p.Glu164Ala, and known Wnt family member 10A (WNT10A mutations c.511C>T (p.Arg171Cys and c.742C>T (p.Arg248* were identified in families with NSTA. The novel EDA and EDAR mutations were predicted as being pathogenic through bioinformatics analyses and structural modeling. Two variants of WNT10A, c.374G>A (p.Arg125Lys and c.125A>G (p.Asn42Ser, were found in patients with NSTA. The two WNT10A variants were predicted to affect the splicing of message RNA, but minigene experiments showed normal splicing of mutated minigenes. This study uncovered the genetic foundations with respect to six families with XLHED or NSTA. We identified six mutations, of which two were novel mutations of EDA and EDAR. This is the first report of a nonsense EDAR mutation leading to NSTA.

    anus and recto-vestibular fistula diagnosed in the first day after birth. At seven months of age, she started to present episodes of recurrent urinary infections and received a diagnosis of neurogenic bladder. At the same time, partial sacral agenesis was noted. Magnetic resonance imaging and computed tomography scan of the spine identified the presence of a fistula coincident with the lombo-sacral dimple described at clinical examination, amputation of the lower portion of the spinal cord with reduced number of nervous roots of the caudus equinus and lipomatous presacral mass. The patient did not present other dysmorphia. Parental radiologic evaluation did not identify sacral abnormalities. COMMENTS: Currarino syndrome is a rare autosomal dominant genetic disease characterized by the triad composed of anal atresia, partial sacral agenesis and presacral tumor. It includes, among others, teratomas, meningoceles, enteric cysts and lipomas, as observed in our patient. Children presenting anorectal abnormalities should be evaluated regarding the presence of Currarino syndrome. The partial sacral agenesis is a major sign of this disease.

  3. Spectral distribution of solo voice and accompaniment in pop music.

    Science.gov (United States)

    Borch, Daniel Zangger; Sundberg, Johan

    2002-01-01

    Singers performing in popular styles of music mostly rely on feedback provided by monitor loudspeakers on the stage. The highest sound level that these loudspeakers can provide without feedback noise is often too low to be heard over the ambient sound level on the stage. Long-term-average spectra of some orchestral accompaniments typically used in pop music are compared with those of classical symphonic orchestras. In loud pop accompaniment the sound level difference between 0.5 and 2.5 kHz is similar to that of a Wagner orchestra. Long-term-average spectra of pop singers' voices showed no signs of a singer's formant but a peak near 3.5 kHz. It is suggested that pop singers' difficulties to hear their own voices may be reduced if the frequency range 3-4 kHz is boosted in the monitor sound.

  4. Treatment of lingual traumatic ulcer accompanied with fungal infections

    Directory of Open Access Journals (Sweden)

    Sella Sella

    2011-09-01

    Full Text Available Background: Traumatic ulcer is a common form of ulceration occured in oral cavity caused by mechanical trauma, either acute or chronic, resulting in loss of the entire epithelium. Traumatic ulcer often occurs in children that are usually found on buccal mucosa, labial mucosa of upper and lower lip, lateral tongue, and a variety of areas that may be bitten. To properly diagnose the ulcer, dentists should evaluate the history and clinical description in detail. If the lesion is allegedly accompanied by other infections, such as fungal, bacterial or viral infections, microbiological or serological tests will be required. One of the initial therapy given for fungal infection is nystatin which aimed to support the recovery and repair processes of epithelial tissue in traumatic ulcer case. Purpose: This case report is aimed to emphasize the importance of microbiological examination in suspected cases of ulcer accompanied with traumatic fungal infection. Case: A 12-year-old girl came to the clinic of Pediatric Dentistry, Faculty of Dentistry, University of Indonesia on June 9, 2011 accompanied with her mother. The patient who had a history of geographic tongue came with complaints of injury found in the middle of the tongue. The main diagnosis was ulcer accompanied with traumatic fungal infection based on the results of swab examination. Case management: This traumatic ulcer case was treated with Dental Health Education, oral prophylaxis, as well as prescribing and usage instructions of nystatin. The recovery and repair processes of mucosal epithelium of the tongue then occured after the use of nystatin. Conclusion: It can be concluded that microbiological examination is important to diagnose suspected cases of ulcer accompanied with traumatic fungal infection. The appropriate treatment such as nystatin can be given for traumatic fungal infection.Latar belakang: Ulkus traumatic merupakan bentuk umum dari ulserasi rongga mulut yang terjadi akibat trauma

  9. The auditory scene: an fMRI study on melody and accompaniment in professional pianists.

    2014-11-15

    The auditory scene is a mental representation of individual sounds extracted from the summed sound waveform reaching the ears of the listeners. Musical contexts represent particularly complex cases of auditory scenes. In such a scenario, melody may be seen as the main object moving on a background represented by the accompaniment. Both melody and accompaniment vary in time according to harmonic rules, forming a typical texture with melody in the most prominent, salient voice. In the present sparse acquisition functional magnetic resonance imaging study, we investigated the interplay between melody and accompaniment in trained pianists, by observing the activation responses elicited by processing: (1) melody placed in the upper and lower texture voices, leading to, respectively, a higher and lower auditory salience; (2) harmonic violations occurring in either the melody, the accompaniment, or both. The results indicated that the neural activation elicited by the processing of polyphonic compositions in expert musicians depends upon the upper versus lower position of the melodic line in the texture, and showed an overall greater activation for the harmonic processing of melody over accompaniment. Both these two predominant effects were characterized by the involvement of the posterior cingulate cortex and precuneus, among other associative brain regions. We discuss the prominent role of the posterior medial cortex in the processing of melodic and harmonic information in the auditory stream, and propose to frame this processing in relation to the cognitive construction of complex multimodal sensory imagery scenes.

    To examine the association between frequency of family member accompaniment to medical visits and heart failure (HF) self-care maintenance and management and to determine whether associations are mediated through satisfaction with provider communication. Cross-sectional survey of 150 HF patients seen in outpatient clinics. HF self-care maintenance and management were assessed using the Self-Care of Heart Failure Index. Satisfaction with provider communication was assessed using a single question originally included in the American Board of Internal Medicine Patient Satisfaction Questionnaire. Frequency of family member accompaniment to visits was assessed using a single-item question. We performed regression analyses to examine associations between frequency of accompaniment and outcomes. Mediation analysis was conducted using MacKinnon's criteria. Overall, 61% reported accompaniment by family members to some/most/every visit. Accompaniment to some/most/every visit was associated with higher self-care maintenance (β = 6.4, SE 2.5; p = 0.01) and management (β = 12.7, SE 4.9; p = 0.01) scores. Satisfaction with provider communication may mediate the association between greater frequency of accompaniment to visits and self-care maintenance (1.092; p = 0.06) and self-care management (1.428; p = 0.13). Accompaniment to medical visits is associated with better HF self-care maintenance and management, and this effect may be mediated through satisfaction with provider communication. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available The current research paper attempted at investigating the use of prepositions of standard, prepositions of possession and prepositions of accompaniment by some Jordanian learners of English. A total of 53 Jordanian English Majors participated in the study from the department of English language at Princess Alia University College. In collecting the needed data for the purpose of the study, the researchers employed fifteen items of a multiple choice test. The results of the study showed that Jordanian learners of English encountered moderate difficulty in learning the three aforesaid usages of prepositions. This difficulty is ascribed mainly to first language interference more than intralingual interference. It was also found that prepositions of standard are the most difficult to learn by the participants, followed by prepositions of accompaniment and prepositions of possession respectively.       Keywords: First language Interference, Intralingual Interference, Prepositions of Standard, Prepositions of Accompaniment, Prepositions of Possession

    Agenesis of the corpus callosum (AgCC), characterized by developmental absence of the corpus callosum, is one of the most common congenital brain malformations. To date, there are limited data on the neuropsychological consequences of AgCC and factors that modulate different outcomes, especially in children. This study aimed to describe general intellectual, academic, executive, social and behavioral functioning in a cohort of school-aged children presenting for clinical services to a hospital and diagnosed with AgCC. The influences of age, social risk and neurological factors were examined. Twenty-eight school-aged children (8 to 17 years) diagnosed with AgCC completed tests of general intelligence (IQ) and academic functioning. Executive, social and behavioral functioning in daily life, and social risk, were estimated from parent and teacher rated questionnaires. MRI findings reviewed by a pediatric neurologist confirmed diagnosis and identified brain characteristics. Clinical details including the presence of epilepsy and diagnosed genetic condition were obtained from medical records. In our cohort, ~50% of children experienced general intellectual, academic, executive, social and/or behavioral difficulties and ~20% were functioning at a level comparable to typically developing children. Social risk was important for understanding variability in neuropsychological outcomes. Brain anomalies and complete AgCC were associated with lower mathematics performance and poorer executive functioning. This is the first comprehensive report of general intellectual, academic, executive social and behavioral consequences of AgCC in school-aged children. The findings have important clinical implications, suggesting that support to families and targeted intervention could promote positive neuropsychological functioning in children with AgCC who come to clinical attention.

    2017-06-01

    Full Text Available Electoral observation has become an essential exercise for the development of electoral democracy. The proliferation of organizations monitoring elections makes necessary to distinguish real «election observation activities», from other similar activities, such as «electoral accompaniment». Independence is an essential element that must be respected by true electoral observation organizations. Accordingly, the lack of independence in some of these organizations transforms them into «intervened electoral observation» actors, dowgrading its credibility and reliability. Hence, the last electoral processes that have taken place in Venezuela, provide the necessary factual basis to distinguish oas election observation missions, from unasur accompaniment missions.

    In summary, a very complex anomaly, including agenesis of the neural arch of the axis, hypomorphogenesis of the cervical spine at the C5-C6 level with a partial ''blocked'' vertebra and disability of the upper cervical spine, is reported in a 31-year-old man. The anomalies associated with these changes are described in detail in the text and illustrated radiologically. The relationship of the embryological alterations in contrast with the normal is described and emphasized, particularly in the upper cervical area. It is stressed that narrowing of the space from the back of the odontoid (or the posterior lip of the foramen magnum) is a direct result of the complex anomalies described in this case, producing compression of the medulla and/or the upper cervical spinal cord. The literature on this subject is reviewed in depth. (orig.)

  6. Photographic measurements of the diffuse light in the coma cluster

    Thuan, T.X.; Kormendy, J.

    1977-01-01

    The diffuse background light in the Coma cluster is measured using isodensity tracings of B, G, V, and R photographic plates taken with the Palomar 1.2-m Schmidt telescope. The isodensity contours are calibrated using the star profile derived by Kormendy (1973). Between 4 and 14 arc min from the center, the surface brightness of the diffuse light decreases from approximately 26 to approximately 28 G magnitudes arc sec -2 . The total magnitude in this annulus is G = 11.22, which is approximately 45 percent of the light in galaxies alone, or approximately 30 percent of the total. This does little to alleviate the ''missing mass'' problem. The isodensity contours and the equivalent profile of the diffuse light closely parallel the distribution of light in galaxies, implying no strong mass segregation. However, the background light appears to be bluer than the galaxies. This is consistent with the hypothesis that the background consists of stars tidally stripped from galaxies, which generally become bluer at larger radii. The present technique is very different from methods used in the past. Comparison of a variety of measurements shows that a reasonably consistent body of data on the background light now exists

    The study of meal patterns and overall diet in relation to health outcomes may be more important than focusing on single nutrients or food groups. The present study aimed to explore the composition of main meals and snacks in the Australian population and examine associations between meat/poultry/fish and other foods. The study utilised 24 h recalls. Meal composition was defined based on average intakes of food groups per meal disaggregated from all food sources. 2011-12 National Nutrition and Physical Activity Survey. Australian people (n12153) aged 2 years or above. Overall, breakfast was the smallest meal of the day, typically consisting of grains, dairy products and fruit. Lunch was the second largest meal, consisting mostly of grains, non-starchy vegetables and meat/poultry/fish. The largest meal was dinner, comprising meat/poultry/fish, vegetables (starchy and non-starchy), grains and often including discretionary beverages (children) or alcohol (adults). The main food groups consumed at snacking occasions were dairy, fruit, discretionary foods and beverages (including alcohol for adults). The most frequently consumed meat types were beef and chicken at dinner and ham at lunch. Non-starchy vegetables were accompanying foods for red meat, poultry and fish/seafood consumed in varying portion sizes, but did not accompany processed meat. The present study considered meat, poultry and fish as the meal centre and their accompaniments of other food groups at different eating occasions. These findings expand the background evidence for health professionals developing meal-based framework/guidelines and public health messages.

  9. CT evaluation of the bile ducts in patients with fatty liver

    Quint, L.E.; Glazer, G.M.

    1984-01-01

    Computed tomographic (CT) evaluation of the bile ducts in the fatty liver can be difficult, since hepatic attenuation decreases with increased triglyceride content, and liver parenchyma may become isodense with bile. Forty-seven patients with fatty infiltration of the liver were retrospectively identified. In 7 of these patients, attenuation of liver and bile differed by less than 10 HU. In 2 patients, dilated intrahepatic ducts were invisible using CT, because bile was isodense with fatty liver parenchyma. Thus, the fatty liver presents a potential pitfall in CT evaluation of the bile ducts. For maximal accuracy scans should be obtained both before and after administration of intravenous urographic contrast material

    Tooth agenesis is one of the predominant developmental anomalies in humans, usually affecting the permanent dentition generated by sequential tooth formation and, in most cases, caused by mutations perturbing epithelial Wnt/β-catenin signaling. In addition, loss-of-function mutations in the Wnt feedback inhibitor AXIN2 lead to human tooth agenesis. We have investigated the functions of Wnt/β-catenin signaling during sequential formation of molar teeth using mouse models. Continuous initiation of new teeth, which is observed after genetic activation of Wnt/β-catenin signaling in the oral epithelium, was accompanied by enhanced expression of Wnt antagonists and a downregulation of Wnt/β-catenin signaling in the dental mesenchyme. Genetic and pharmacological activation of mesenchymal Wnt/β-catenin signaling negatively regulated sequential tooth formation, an effect partly mediated by Bmp4. Runx2 , a gene whose loss-of-function mutations result in sequential formation of supernumerary teeth in the human cleidocranial dysplasia syndrome, suppressed the expression of Wnt inhibitors Axin2 and Drapc1 in dental mesenchyme. Our data indicate that increased mesenchymal Wnt signaling inhibits the sequential formation of teeth, and suggest that Axin2 / Runx2 antagonistic interactions modulate the level of mesenchymal Wnt/β-catenin signaling, underlying the contrasting dental phenotypes caused by human AXIN2 and RUNX2 mutations. © 2018.

    To assess the effect of hydration status on renal medullary attenuation and to evaluate the incidence of dense renal medulla, as seen on unenhanced CT. We prospectively studied unenhanced CT scans of 12 healthy volunteers. Obtained done after 10 hours and 15 hours of dehydration and after oral intake of 2L of water. BUN/Cr, urine specific gravity, urine osmole and hematocrit were evaluated after 10 hours of dehydration. CT images were reviewed for the presence of dense renal medulla and differential attenuation of dense renal and isodense medulla and cortex at the same level. The density changes of renal medulla after hydration were evaluated. and CT findings were compared with the results of biochemical studies. In addition, we retrospectively reviewed the CT scans of 200 consecutive patients for evaluation of the incidence of dense renal medulla. In 8 of 12 volunteers, dense renal medulla was seen on CT scan after dehydration. Mean attenuation was 71.3±10.42HU after 10 hours of dehydration, 68.6±13.54HU after 15 hours, and 34.5±11.47HU after hydration. No significant attenuation differences were detected between 10 hours and 15 hours of dehydration, but significantly lower attenuation values were noted after hydration. For isodense medulla, the mean attenuation value was 35.7±7.9HU after 10 hours of dehydration, 39.58±9.66HU after 15 hours, and 36.58±7.77HU after hydration. The mean attenuation values of cortex were 35.9±5.95HU after 10 hours of dehydration. 37.58±5.95HU after 15 hours, and 37.08±9.75HU after hydration. With regard not only to duration of dehydration, but also ti hydration, no differences in attenuation values were noted for renal cortex or isodense renal medulla. However, higher density was noted in dense renal medulla than in isodense medulla or cortex for the same duration of dehydration. After hydration, complete resolution was seen at five of eight sites and incomplete resolution at three of eight sites. There was no correlation

    Full Text Available Abstract Background While models of autism spectrum conditions (ASC are emerging at the genetic level of analysis, clear models at higher levels of analysis, such as neuroanatomy, are lacking. Here we examine agenesis of the corpus callosum (AgCC as a model at the level of neuroanatomy that may be relevant for understanding self-referential and social-cognitive difficulties in ASC. Methods We examined performance on a wide array of tests in self-referential and social-cognitive domains in a patient with both AgCC and a diagnosis of ASC. Tests included a depth-of-processing memory paradigm with self-referential and social-cognitive manipulations, self-report measures of self-consciousness, alexithymia, and empathy, as well as performance measures of first-person pronoun usage and mentalizing ability. The performance of the AgCC patient was compared to a group of individuals with ASC but without AgCC and with neurotypical controls. These comparison groups come from a prior study where group differences were apparent across many measures. We used bootstrapping to assess whether the AgCC patient exhibited scores that were within or outside the 95% bias-corrected and accelerated bootstrap confidence intervals observed in both comparison groups. Results Within the depth-of-processing memory paradigm, the AgCC patient showed decreased memory sensitivity that was more extreme than both comparison groups across all conditions. The patient’s most pronounced difficulty on this task emerged in the social-cognitive domain related to information-processing about other people. The patient was similar to the ASC group in benefiting less from self-referential processing compared to the control group. Across a variety of other self-referential (i.e. alexithymia, private self-consciousness and social-cognitive measures (i.e. self-reported imaginative and perspective-taking subscales of empathy, mentalizing, the AgCC patient also showed more extreme scores than

    The phenomenon in which a certain smell evokes a specific memory is known as the Proust phenomenon. Odor-evoked autobiographic memories are more emotional than those elicited by other sensory stimuli. The results of our previous study indicated that odor-evoked autobiographic memory accompanied by positive emotions has remarkable effects on various psychological and physiological activities, including the secretion of cytokines, which are immune-signaling molecules that modulate systemic inflammation. In this study, we aimed to clarify the neural substrates associated with the interaction between odor-evoked autobiographic memory and peripheral circulating cytokines. We recruited healthy male and female volunteers and investigated the association between brain responses and the concentration of several cytokines in the plasma by using positron emission tomography (PET) recordings when an autographic memory was evoked in participants by asking them to smell an odor that was nostalgic to them. Participants experienced positive emotions and autobiographic memories when nostalgic odors were presented to them. The levels of peripheral proinflammatory cytokines, such as the tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), were significantly reduced after experiencing odor-evoked autobiographic memory. Subtraction analysis of PET images indicated that the medial orbitofrontal cortex (mOFC) and precuneus/posterior cingulate cortex (PCC) were significantly activated during experiences of odor-evoked autobiographic memory. Furthermore, a correlation analysis indicated that activities of the mOFC and precuneus/PCC were negatively correlated with IFN-γ concentration. These results indicate that the neural networks including the precuneus/PCC and mOFC might regulate the secretion of peripheral proinflammatory cytokines during the experience of odor-evoked autobiographic memories accompanied with positive emotions.

  20. The impact of parental accompaniment in paediatric trauma: a helicopter emergency medical service (HEMS) perspective.

    Cowley, Alan; Durge, Neal

    2014-05-13

    Major trauma remains a significant cause of mortality and morbidity in young people and adolescents throughout the western world. Both the physical and psychological consequences of trauma are well documented and it is shown that peri-traumatic factors play a large part in the emotional recovery of children involved in trauma. Indeed, parental anxiety levels may play one of the biggest roles. There are no publically available guidelines on pre-hospital accompaniment, and where research has been done on parental presence it often focuses primarily on the parents or staff, rather than the child themselves. Whilst acknowledging the impact on parents and staff, the importance of the emotional wellbeing of the child should be reinforced, to reduce the likelihood of developing symptoms in keeping with post-traumatic stress disorder. This non-systematic literature review, aims to examine the impact of parental accompaniment to hospital, following paediatric trauma, and to help pre-hospital clinicians decide whether accompaniment would be of benefit to their patient population. The lack of published data does not enable a formal recommendation of parental accompaniment in the helicopter to be mandated, though it should be the preference in land based conveyance. Future research is needed into the emotional recovery of children after trauma, as well as the experiences of patient, parent and staff during conveyance.

  1. Target-Dependent Structural Changes Accompanying Long-Term Synaptic Facilitation in Aplysia Neurons

    The mechanisms underlying structural changes that accompany learning and memory have been difficult to investigate in the intact nervous system. In order to make these changes more accessible for experimental analysis, dissociated cell culture and low-light-level video microscopy were used to examine Aplysia sensory neurons in the presence or absence of their target cells. Repeated applications of serotonin, a facilitating transmitter important in behavioral dishabituation and sensitization, produced growth of the sensory neurons that paralleled the long-term enhancement of synaptic strength. This growth required the presence of the postsynaptic motor neuron. Thus, both the structural changes and the synaptic facilitation of Aplysia sensorimotor synapses accompanying long-term behavioral sensitization can be produced in vitro by applying a single facilitating transmitter repeatedly. These structural changes depend on an interaction of the presynaptic neuron with an appropriate postsynaptic target.

    Dynamic computed tomography was used to study 19 patients with hormone-secreting microadenomas: 10 prolactin-secreting, 5 growth-hormone-secreting, and 4 adrenocorticotropic-hormone-secreting. A distorted and displaced tuft indicates a mass effect mainly on the opposite side. A mid-situated tuft with a disproportionately small size compared with the size of the anterior lobe indicates a mass effect mainly in the midportion. An area into which a high density at the tuft definitely spreads indicates a normal anterior lobe; an area in which less increase in the density than in the former area is observed indicates an abnormal mass. In the time-density curve, the former area represents the vascular pattern or the hypervascular extravasation pattern, while the latter area represents the extravasation of the contrast material in a hypovascular tissue. Only eight microadenomas appeared as a less enhanced mass. The rest of the cases exhibited adenomas isodense to the normal pituitary gland. A dynamic CT scan was particularly useful in the diagnosis of isodense adenomas. In these isodense adenomas, the dynamic CT scan facilitated the identification of an adenoma as a relatively less enhanced area than the normal gland. The extent of a normal pituitary gland could also be identified by means of dynamic CT. In three of the 11 isodense microadenomas, the conventional diagnostic criteria, such as infundibulum displacement, abnormal height and upward convexity of a pituitary-microadenoma complex, and changes in the sellar floor, were not encountered. A dynamic CT scan, however, enabled us to diagnose the localization of microadenomas in two of these three cases. In 18 of the 19 microadenomas, dynamic CT findings as to the localization of a microadenoma and the normal pituitary gland correlated well with the surgical findings. (J.P.N.)

    "Death and its approach represent a field of study for nurses": thus ended his article Montserrat Salvador Borrell in Revista ROL de Enfermería in November 2010. Address it also from the point of view of the soul brings perspective and gives horizon in the sense of one greater understanding. Death, contemplated and lived exclusively from the material side, flees from as a not only traumatic event for which the experience but also unsurpassed for loved ones. Paradoxically, it's a more natural and frequent phenomenon. Why humans so hard that naturalness? Because we have not cultivated, sometimes not even recognized, other spiritual nature which forms us and who has the key to give sense to the decisive events. For many spiritual traditions, death is birth to another world that, from here, we call beyond. In accompaniment of soul seminars, based on the teachings transmitted by Elisabeth Kübler Ros and Marie Lise Labonte, patterns are learned to accompany the personality and soul--which does not always go according to the time of split--and to help the soul to rediscover his way toward the light, toward the origin. The soul knows it well, but the emotional ties forged during his earthly journey can retain it and hinder the process, which becomes slow and painful. The accompaniment of the soul is a "service" human, social and spiritual. Guides in a forgotten and often feared territory is a relief. You have guides to prepare the great journey allows, especially, make peace with himself with others I with the world. The Egyptians used the symbol of the solar boat, which waits for the deceased to cross the great waters. Nurses are, unknowingly, barqueras of small and large transits of existence.

    Non Syndromic tooth agenesis is a congenital anomaly with significant medical, psychological and social ramifications. There is sufficient evidence to hypothesize that locus for this condition can be identified by candidate genes. The aim of this study was to test whether MSX1 671 T>C gene variant was involved in etiology of Non Syndromic tooth agenesis in Raichur Patients. Blood samples were collected with informed consent from 50 subjects having Non Syndromic tooth agenesis and 50 controls. Genomic DNA was extracted from the blood samples, Polymerase Chain Reaction was performed (PCR) and Restriction Fragment Length Polymorphism (RFLP) was performed for digestion products that were evaluated. The RESULTS showed positive correlation between MSX1671 T>C gene variant and Non Syndromic tooth agenesis in Raichur Patients. MSX1 671 T>C gene variant may be a good screening marker for Non Syndromic tooth agenesis in Raichur Patients .

    Full Text Available This individual prospective cohort study aims to report and analyze the symptoms preceding and accompanying the facial paresis in Bell’s palsy (BP. Two hundred sixty-nine patients affected by BP with a maximum delay of 48 hours from the onset were enrolled in the study. The evolution of the facial paresis expressed as House-Brackmann grade in the first 10 days and its correlation with symptoms were analyzed. At the onset, 136 patients presented postauricular pain, 114 were affected by dry eye, and 94 reported dysgeusia. Dry mouth was present in 54 patients (19.7%, facial pain, hyperlacrimation, aural fullness, and hyperacusis represented a smaller percentage of the reported symptoms. After 10 days, 39.9% of the group had a severe paresis while 10.2% reached a complete recovery. Dry mouth at the onset was correlated with severe grade of palsy and was prognostic for poor recovery in the early period. These outcomes lead to the deduction that the nervus intermedius plays an important role in the presentation of the BP and it might be responsible for most of the accompanying symptomatology of the paresis. Our findings could be of important interest to early address a BP patient to further examinations and subsequent therapy.

    Full Text Available Secondary injuries especially extremity fractures may be seen concurrently with traumatic brain injury (TBI. Peripheral nerve damages may accompany to these fractures and may be missed out, especially in acute stage. In this case report; damage of radial, ulnar and median nerves which was developed secondarily to distal humerus fracture that could not be detected in acute stage, in a patient who had motor vehicle accident (MVA. 29-year-old male patient was admitted with weakness in the right upper extremity. 9 months ago, he had traumatic brain injury because of MVA, and fracture of distal humerus was detected in follow-ups. Upon the suspect of the peripheral nerve injury, the diagnosis was confirmed with ENMG. The patient responded well to the rehabilitation program treatment. In a TBI patient, it must be kept in mind that there might be a secondary trauma and therefore peripheral nerve lesions may accompany to TBI.

    1999-01-01

    The thought on ethics, enhances by accompanying patients or human-beings reaching end of life, belong to major themes which have for years been dealt with by philosophers and monks. The physicians, who by nature accompany and live with their patient this life period a sometimes close relationship, have conceived within deontology a wonderful expression of what ethics inspired them. Reading articles 37 and 38 of the Code of Ethics brings a clear, precise and qualified answer to the question raised by the title. We easily find out the main principles which would be the guideline to the doctor's behaviour coping with this situation: providing suitable and continue cares to maintain the quality of a life which comes to end, respecting dignity. Relieving suffers, morally assisting, comforting the family, knowing to limit the cares reasonably. The sensitive and human expression sums up pretty well the particularities essential to all (physicians, health professionals or volunteers) who have accepted this heavy task.

    Low-temperature storage and transport of blueberries is widely practiced in commercial blueberry production. In this research, the storage life of blueberries was extended at low temperature, but fruit stored for 30 d at 0°C pitted after 2d at room-temperature. Fruit cellular structure and physiological parameters accompanying pitting in blueberries were changed. The objective of this research was to characterise properties of energy metabolism accompanying pitting in blueberries during storage, including adenosine phosphates and mitochondrial enzymes involved in stress responses. Physiological and metabolic disorders, changes in cell ultrastructure, energy content and ATPase enzyme activity were observed in pitting blueberries. Energy shortages and increased activity of phenylalanine ammonia lyase (PAL) and lipoxygenase (LOX) were observed in fruit kept at shelf life. The results suggested that sufficient available energy status and a stable enzymatic system in blueberries collectively contribute to improve chilling tolerance, thereby alleviating pitting and maintaining quality of blueberry fruit in long-term cold storage.

    2014-01-01

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

  15. Updating the premotor theory: the allocation of attention is not always accompanied by saccade preparation.

    Belopolsky, Artem V; Theeuwes, Jan

    2012-08-01

    There is an ongoing controversy regarding the relationship between covert attention and saccadic eye movements. While there is quite some evidence that the preparation of a saccade is obligatory preceded by a shift of covert attention, the reverse is not clear: Is allocation of attention always accompanied by saccade preparation? Recently, a shifting and maintenance account was proposed suggesting that shifting and maintenance components of covert attention differ in their relation to the oculomotor system. Specifically, it was argued that a shift of covert attention is always accompanied by activation of the oculomotor program, while maintaining covert attention at a location can be accompanied either by activation or suppression of oculomotor program, depending on the probability of executing an eye movement to the attended location. In the present study we tested whether there is such an obligatory coupling between shifting of attention and saccade preparation and how quickly saccade preparation gets suppressed. The results showed that attention shifting was always accompanied by saccade preparation whenever covert attention had to be shifted during visual search, as well as in response to exogenous or endogenous cues. However, for the endogenous cues the saccade program to the attended location was suppressed very soon after the attention shift was completed. The current findings support the shifting and maintenance account and indicate that the premotor theory needs to be updated to include a shifting and maintenance component for the cases in which covert shifts of attention are made without the intention to execute a saccade.

    The aims of this study were to evaluate the prevalence of dental anomalies in Turkish patients with different types of cleft lip and palate (CLP) and investigate the relationship between the type of cleft and the dental anomaly. Eighty-eight patients with cleft lip and/or palate (mean age: 14.1 ± 6.4 years) were enrolled in this retrospective study. Dental models, panoramic radiographs, and intraoral photographs of these patients were evaluated to detect any maxillary dental anomaly (number and size anomalies). Two hundred fifty unaffected subjects (mean age: 15.2 ± 7.2 years) composed the control group. Data were evaluated using the independent t test, χ, Fischer exact test, and the odds ratio. Dental anomaly frequency was significantly higher in the cleft group compared with the control group. Tooth agenesis was the most common dental anomaly, followed by microdontia and supernumerary tooth. Lateral incisor agenesis was seen in 69% of the unilateral CLP, in 78% of the bilateral CLP, and in 18% of the cleft palate patients. A significant association was revealed between the right unilateral CLP and the right lateral incisor agenesis (P = 0.0001), the left unilateral CLP and the left lateral incisor agenesis (P = 0.002), and the bilateral CLP and the bilateral lateral incisor agenesis (P = 0.0001). Dental anomalies are more frequently seen in patients with CLP compared with the general population. There is a relationship between the cleft type and the ipsilateral lateral incisor agenesis.

    A novel scheme of two-beam accelerator (TBA) driver based on a linear induction accelerator is considered. In this scheme the bunched beam propagates in the accompanying enhanced microwave that provides the steady longitudinal beam bunching along the whole driver. A travelling wave tube (TWT) is used as the wave-slowing periodic structure. Major merits of the driver scheme in hand are the possibilities of providing the microwave phase and amplitude stability and the preliminary beam bunching at a rather low initial energy (∼ 1 MeV). The numerical simulation has shown that a steady state could be found when electron bunches accompanied by an amplified microwave are simultaneously accelerated in the external electric field. The total power, which is inserted into the beam by the accelerating field, transforms into the microwave power in the steady state. The first set of experiments was fulfilled with the buncher on the base of the JINR LIU-3000 linac (electron beam energy ∼ 600 keV, electron current ∼ 150 A). The considerable level of the amplified microwave power (∼ 5 MW) and high enough bunching parameter (∼ 0.4) were obtained. The electron beam bunching at the frequency of 36.4 GHz was registered by means of the Cherenkov radiation of the electron bunches that occurred at their passing through the special target. The beam keeps a high bunching level at the distance ∼ 10 cm from the TWT exit being accompanied by the amplified microwave

    Cano, Estefanía; Schuller, Gerald; Dittmar, Christian

    2014-12-01

    We present a system for the automatic separation of solo instruments and music accompaniment in polyphonic music recordings. Our approach is based on a pitch detection front-end and a tone-based spectral estimation. We assess the plausibility of using sound separation technologies to create practice material in a music education context. To better understand the sound separation quality requirements in music education, a listening test was conducted to determine the most perceptually relevant signal distortions that need to be improved. Results from the listening test show that solo and accompaniment tracks pose different quality requirements and should be optimized differently. We propose and evaluate algorithm modifications to better understand their effects on objective perceptual quality measures. Finally, we outline possible ways of optimizing our separation approach to better suit the requirements of music education applications.

    Selected phenomena leading to inner shell ionization and being of relevance for nuclear physics are discussed. The selection emphasizes the K-shell ionization induced in head-on collisions by fast light and medium-heavy ions. Cross-sections are reviewed. Effects of multiple inner shell ionization on the K X-ray spectra are illustrated with recent results. Implications for nuclear experiments are noted. Use of atomic observables as clocks for proton induced nuclear reactions is reviewed. Prospects for H.I. reactions are discussed. Preliminary experimental results on the direct K-shell ionization accompanying H.I. fusion reactions are presented. The post-collisional K-shell ionization due to internal conversion of γ-rays is discussed as the dominating contribution to the ionization for residues of dissipative nuclear reactions with Z > 40. Systematics of the corresponding K X-ray multiplicities are presented for rotational nuclei. These multiplicity values can be used for determining cross-sections for e.g. incomplete fusion reactions. Examples of such applications are given. Also discussed is the use of target K X-rays for normalization purposes and of the post-collisional, residue K X-rays in the studies of high spin phenomena. 96 references, 35 figures, 3 tables

    2018-02-01

    Attending to pain-relevant information is crucial to protect us from physical harm. Behavioral studies have already suggested that during anticipation of pain somatosensory input at the body location under threat is prioritized. However, research using daily life cues for pain, especially movements, is lacking. Furthermore, to our knowledge, no studies have investigated cortical processing associated with somatosensory processing during threatened movements. The current study aims to investigate whether movements accompanying pain automatically steer attention toward somatosensory input at the threatened location, affecting somatosensory evoked potentials (SEPs). Healthy volunteers were cued to perform movements with the left or the right hand, and one of these movements could be accompanied by pain on the moving hand. During movement anticipation, a task-irrelevant tactile stimulus was presented to the threatened or pain-free hand to evoke SEPs. During anticipation of movements accompanying pain, the N120 component was increased for tactile stimuli at the threatened relative to the hand without pain. Moreover, the P200 SEP was enhanced during anticipation of movements accompanying pain relative to movements without pain, irrespective of which hand was stimulated. These findings show that the anticipation of pain-accompanying movements may affect the processing of somatosensory input, and that this is likely to be driven by attentional processes. This study shows that the anticipation of pain-related movements automatically biases attention toward stimuli at a pain-related location, measured according to SEPs. The present study provides important new insights in the interplay between pain and attention, and its consequences at the cortical level. Copyright © 2017 The American Pain Society.

    Full Text Available International election monitoring has been touted as a regional norm in the Western hemisphere, but recent reforms in Venezuela and Nicaragua substituted a diminished international role of electoral accompaniment. This article traces the initial acceptance and later limitation of international election monitoring in those countries to explore whether the change constitutes norm localization or norm defection. It concludes that the norm is not as well institutionalized in the hemisphere as conventionally thought, and that models need to assess together national and international monitoring capacities.

    Full Text Available The Harmonic Walk is an interactive physical environment designed for learning and practicing the accompaniment of a tonal melody. Employing a highly innovative multimedia system, the application offers to the user the possibility of getting in touch with some fundamental tonal music features in a very simple and readily available way. Notwithstanding tonal music is very common in our lives, unskilled people as well as music students and even professionals are scarcely conscious of what these features actually are. The Harmonic Walk, through the body movement in space, can provide all these users a live experience of tonal melody structure, chords progressions, melody accompaniment, and improvisation. Enactive knowledge and embodied cognition allow the user to build an inner map of these musical features, which can be acted by moving on the active surface with a simple step. Thorough assessment tests with musicians and nonmusicians high school students could prove the high communicative power and efficiency of the Harmonic Walk application both in improving musical knowledge and in accomplishing complex musical tasks.

    To evaluate the therapeutic effect of Longjintonglin Capsules on type IIIA prostatitis accompanied by abnormal semen liquefaction. We selected 140 patients with type IIIA prostatitis accompanied by abnormal semen liquefaction according to the diagnostic standards of the American Institutes of Health (NIH) and treated them with Longjintonglin Capsules orally 3 capsules once tid for 12 weeks. We obtained the NIH Chronic Prostatitis Symptom Indexes (NIH-CPSI), traditional Chinese medicine (TCM) syndrome scores, leukocyte count in the expressed prostatic secretion (EPS), semen liquefaction time, and the results of semen analysis and compared these indicators before and after the treatment. Of the 140 cases, 132 were included in this study, excluding 8 due to their incomplete case histories. Before and after 4, 8 and 12 weeks of medication, the total NIH-CPSI scores were 24.52 ± 5.43, 21.28 ± 4.85, 18.01 ± 4.28, and 14.49 ± 3.65 (P prostatitis were cured and another 72 well responded, with an overall response rate of 78.0%. Of those with abnormal semen liquefaction, 61 were cured, 39 well responded, and 32 failed to respond, with an overall effectiveness rate of 75.8%. Semen analysis showed significantly increased percentage of progressively motile sperm after 4, 8 and 12 weeks of medication as compared with the baseline (P prostatitis accompanied by abnormal semen liquefaction.

    The paper defines the therapeutic and rehabilitation approach to the patients with Angle's classification Class II dento-facial anomalies, accompanied by obstructive sleep apnea (OSA). The proposed comprehensive approach to the diagnostics and treatment of patients with posterior occlusion, accompanied by OSA, allows for objective evaluation of intensity of a dento-facial anomaly and accompanying respiratory disorders in the nasal and oral pharynx, which allows for the pathophysiological mechanisms of OSA to be identified, and an optimal plan for surgical procedures to be developed. The proposed comprehensive approach to the diagnostics and treatment of patients with Angle's classification Class II dento-facial anomalies provides high functional and aesthetic results.

    Objective: To discuss MRI manifestation of Wilson's disease accompanied with central pontine myelinolysis (CPM), and to especially detect the value of diffusion-weighted MRI (DWI) in this disease. Methods: Two cases of Wilson's disease accompanied with CPM were performed with sequent MR examination including T 1 WI, T 2 WI, FLAIR, DWI, and contrast-enhanced MRI (CE MRI) by a 1.5 T magnetic resonance system (Philips gyroscan master). Results: Symmetric long T 1 and T 2 signals were found in central pontine region, lenticular nucleus, caudate nucleus, and thalamus. CEMRI showed no apparent enhanced lesions. DWI showed obviously high signal intensities in central pontine region with apparent diffusion coefficient values fluctuated between (100-300) x 10 -6 mm 2 /s while FLAIR images just showed slightly high signal in the same area, which suggested that cytotoxic edema did in fact exist in CPM. Meanwhile, DWI also showed high signals in bilateral lenticular nucleus with apparent diffusion coefficient values fluctuated between (300-600) x 10 -6 mm 2 /s, however, FLAIR images showed heterogeneous high signals and one case presented low DWI signals in bilateral head of caudate nucleus, all these signs might be explained by mixed-changes of cytotoxic edema and vasogenic edema in long period of Wilson's disease. Conclusion: Wilson's disease and CPM have characteristic MRI manifestation and DWI may be a very useful way to confirm a correct diagnosis. (authors)

    Legal restrictions on abortion access impact the safety and timing of abortion. Women affected by these laws face barriers to safe care that often result in abortion being delayed. Second-trimester abortion affects vulnerable groups of women disproportionately and is often more difficult to access. In Argentina, where abortion is legally restricted except in cases of rape or threat to the health of the woman, the Socorristas en Red, a feminist network, offers a model of accompaniment wherein they provide information and support to women seeking second-trimester abortions. This qualitative analysis aimed to understand Socorristas' experiences supporting women who have second-trimester medication abortion outside the formal health care system. We conducted 2 focus groups with 16 Socorristas in total to understand experiences accompanying women having second-trimester medication abortion who were at 14-24 weeks' gestational age. We performed a thematic analysis of the data and present key themes in this article. The Socorristas strived to ensure that women had the power of choice in every step of their abortion. These cases required more attention and logistical, legal and medical risks than first-trimester care. The Socorristas learned how to help women manage the possibility of these risks and were comfortable providing this support. They understood their work as activism through which they aim to destigmatize abortion and advocate against patriarchal systems denying the right to abortion. Socorrista groups have shown that they can provide supportive, women-centered accompaniment during second-trimester medication abortions outside the formal health care system in a setting where abortion access is legally restricted. Second-trimester self-use of medication abortion outside of the formal health system supported by feminist activist groups could provide an alternative model for second-trimester care worldwide. More research is needed to document the safety and

    Full Text Available MURCS association (Mullerian hypoplasia/aplasia, renal agenesis and cervicothoracic somite dysplasia is emerging as the second most frequent cause of primary amenorrhoea after Turner syndrome. Seven cases have been described and analysed. All cases had absence of uterus and tubes 85% had cervical spine abnormalities such as vertebral fusion, hypoplasia of vertebrae or butterfly vertebrae and short stature and 28% had renal agenesis or ectopy. The latter finding is in contrast to the reports in world literature where the frequency of renal agenesis is higher. There was no familial incidence in these seven cases lending credence to the belief that the association is essentially sporadic.

    Full Text Available Congenitally missing teeth are the most commonly seen dental anomalies. Agenesis of the permanent first molar has the least frequency of all the tooth types, and it usually occurs in association with oligodontia or anodontia. Thus, agenesis of the bilateral maxillary first permanent molar is an extremely rare occurrence, and no such case has been reported in ethnic Saudi Arabian population. We hereby report a case of nonsyndromic bilateral congenitally missing maxillary first permanent molar in an eight-year-old Saudi female patient. Comprehensive oral rehabilitation was done for the patient. The implications of the tooth agenesis are also discussed. The prognosis of this case is presented.

    Full Text Available OBJECTIVE: The aim of this study was to determine the prevalence of open angle glaucoma in first-degree relatives accompanying POAG patients during routine examination in a reference hospital. METHOD: First-degree relatives of primary open angle glaucoma patients who accompanied their relatives to the glaucoma service of a reference hospital were screened for glaucoma. RESULTS: One-hundred and one first-degree relatives were examined, of which 56.4% had never had their intraocular pressure measured. 10.9% had previously been diagnosed with glaucoma, and 5.9% were newly diagnosed during this study. CONCLUSIONS: The eye examination of first-degree relatives identified a significant percentage of individuals with glaucoma. Despite being first-degree relatives of glaucoma patients, 56.4% of the companions had never had their eye pressure measured, demonstrating a lack of awareness about this disease.

    Full Text Available Au-Ag noble metal wastes represent a wide range of waste types and forms, with various accompanying metallic elements.The presented leaching strategy for Au-Ag contained in circuit boards (PCBs aims at gaining gold and silver in the metallic form.Application of the proposed ammonium thiosulphate leaching process for the treatment of the above mentioned Au-Ag containing wastesrepresents a practical, economic and at the same time an ecological solution. The ammonium thiosulphate based leaching of gold and silverfrom PCBs waste, using crushing as a pretreatment, was investigated. It was possible to achieve 98 % gold and 93 % silver recovery within48 hours of ammonium thiosulphate leaching. This type of leaching is a better leaching procedure for recovery of gold and silver from PCBwaste than the classical toxic cyanide leaching. 84 % Cu, 82 % Fe, 77 % Al, 76 % Zn, 70 % Ni, 90 % Pd, 88 % Pb and 83 % Sn recovery ofthe accompanying metals was achieved, using sulphuric acid with hydrogen peroxide, sodium chloride and aqua regia. A four steps leachingprocess gave a very satisfactory yield and a more rapid kinetics for all observed metals solubilization than other technologies.

    Myelomeningocele is a complex central nervous system malformation mostly associated with other neural and extraneural anomalies. A rare special feature of the forehead and skull was observed in myelomeningocele. Here, we present several patients with myelomeningocele, severe hydrocephalus, and interfrontal encephalocele accompanied by metopic suture widening and abnormally shaped frontal bones. Five children with this feature were enrolled in this series. The age, sex, location of myelomeningocele sac, neurological deficits, hydrocephalus and history of shunt surgery, and follow-up period were evaluated. Patients were aged from 1 to 12 months (mean, 6 months). All patients were male. Most sacs were located in lumbar and lumbosacral areas. Neurological deficits varying from only sphincter problem to paraplegia were found in all patients. Hydrocephalus was found in all children that needed a shunt procedure. Asymptomatic Chiari malformation, interfrontal encephalocele, and corpus callosum agenesis were evident in five, five, and three patients, respectively. Anterior fontanel anomalies known as interfrontal encephalocele associated with myelomeningocele have been reported before. The patients have an open metopic suture extending widely to the nasal radix producing hypertelorism accompanied by interfrontal herniation of frontal lobes. The associated hydrocephalus exaggerates the anomaly. Treatment of accompanying hydrocephalus is advised to decrease the severity of frontal lobe herniation. Some patients may need frontal bone reconstruction surgery to provide cosmetic correction at the place of the midline frontal bone defect.

    Full Text Available Hemp fibres belong to the group of natural, cellulose bast fibres. These fibres have exceptional properties such as: antimicrobial effect, absence of allergy effect, extraordinary sorption properties, good electro-physical properties (small static electricity in regard to other cellulose fibres as well as high values of breaking strength (the natural fibre with the highest strength. However, hemp fibres have some defects: heterogeneous chemical composition, large quantity of accompanying substances (lignin pectins, waxes and unsatisfactory fineness and eveness. It is possible to a great extent to eliminate or reduce, the defects of hemp fibres by of appropriate modification treatments. In order to determine the appropriate modification treatment of hemp fibres, the dependences between the chemical composition, fineness and electric resistance of hemp fibres were presented in this paper. In the experimental part of the paper, by the application of a procedure for the determination of the chemical composition, the accompanying supstances of hemp fibres were gradually removed. After each phase some fibrous substrates were separated. After that the fineness and electric resistance were determined. This experiment was conducted in order to define the influence of each component of hemp fibres on the fineness and electric resistance. In this paper, hemp fibres were modified by an aqueous solution of sodium hydroxide, under different conditions of modification. The influence of modification conditions on the fineness and electric resistance were studied.

    Interobserver agreement in assessing brain CT-scans is, in general, high. The extent, however, to which such agreement is caused by bias through knowledge of other clinical details remains uncertain. The hypothesis that observers are somehow prejudiced before assessing ambiguous, CT-scans in this particular situation was tested. Sixteen neurologists and 16 radiologists volunteered to interpret two ambiguous brain CT-scans, with regard to the presence or absence of a lacunar infarct in the region of the internal capsule. The scans were accompanied by 'patient' information that was or was not suggestive of a stroke. These scans were camouflaged by a variety of other scans, to be assessed in the same way, to mask the purpose of the study. I was assumed that the observers, in their assessments of the scans, would somehow let their ratings of the likelihood of a lacunar infarction in or near the internal capsule be subject to the accompanying information. Results showed lower ratings produced by neurologists (i.e., less likelihood of an infarction) than by radiologists in the majority of all assessments, but no bias by the accompanying information.

    Our aim was to clarify the frequency of cardiovascular border obliteration on frontal chest radiography and to prove that the phrenic nerve with accompanying vessels can be considered as a cause of obliteration of cardiovascular border on an otherwise normal chest radiography. Two radiologists reviewed chest radiographs and computed tomography (CT) images of 100 individuals. CT confirmed the absence of intrapulmonary or extrapulmonary abnormalities in all of them. We examined the frequency of cardiovascular border obliteration on frontal chest radiography and summarized the causes of obliteration as pericardial fat pad, phrenic nerve, intrafissure fat, pulmonary vessels, and others, comparing them with CT in each case. Cardiovascular border was obliterated on frontal chest radiography in 46 cases on the right and in 61 on the left. The phrenic nerve with accompanying vessels was found to be a cause of obliteration in 34 of 46 cases (74%) on the right and 29 of 61 (48%) cases on the left. The phrenic nerve was the most frequent cause of cardiovascular border obliteration on both sides. The phrenic nerve with accompanying vessels, forming a prominent fold of parietal pleura, can be attributed as a cause of cardiovascular border obliteration on frontal chest radiography.

    As the micro plasma instability due to the plasma non-uniformity in magnetosphere, there is the instability of drift Alfven wave. With the data obtained with the network of multiple observation points for geomagnetism, attempt was made to prove the hypothesis that the instability of drift Alfven wave due to the electron temperature gradient at the inner boundary of plasma sheet may be one of the causes for the geomagnetic pulsation (Pi 1) accompanying polar magnetic storm. Up to date, final conclusion is yet impossible as to the problems in it due to the discussion based on the data from widely separated observation points. The installation of economically efficient multi-point observation network is necessary for the solution. (Mori, K.)

    The horizontal air motions accompanying the development of a planetary wave critical layer are presently investigated on the sphere, in terms of wave amplitude, the characteristics of the zonal flow, and dissipation. While attention is given to adiabatic motions, which should furnish an upper bound on the redistribution of conserved quantities by eddy stirring, nonconservative processes may be important in determining how large a role eddy stirring actually plays in the redistribution of atmospheric constituents. Nonconservative processes may also influence tracer distributions by directly affecting dynamics.

  10. Imaging Action Potential in Single Mammalian Neurons by Tracking the Accompanying Sub-Nanometer Mechanical Motion.

    2018-03-28

    Action potentials in neurons have been studied traditionally by intracellular electrophysiological recordings and more recently by the fluorescence detection methods. Here we describe a label-free optical imaging method that can measure mechanical motion in single cells with a sub-nanometer detection limit. Using the method, we have observed sub-nanometer mechanical motion accompanying the action potential in single mammalian neurons by averaging the repeated action potential spikes. The shape and width of the transient displacement are similar to those of the electrically recorded action potential, but the amplitude varies from neuron to neuron, and from one region of a neuron to another, ranging from 0.2-0.4 nm. The work indicates that action potentials may be studied noninvasively in single mammalian neurons by label-free imaging of the accompanying sub-nanometer mechanical motion.

    A pseudo-normalization of infarcted brain parenchyma, similar to the ''fogging effect'' which usually occurs after 2-3 weeks, can be observed on CT performed immediately after endovascular stroke treatment (EST). Goal of this study was to analyze the incidence of this phenomenon and its evolution on follow-up imaging. One hundred fifty-two patients in our database of 949 patients, who were treated for acute stroke between January 2010 and January 2015, fulfilled the inclusion criteria of (a) EST for an acute stroke in the anterior circulation, (b) an ASPECT-score < 10 on pre-interventional CT, and (c) postinterventional CT imaging within 4.5 h after the procedure. Two independent reviewers analyzed imaging data of these patients. Transformation of brain areas from hypoattenuated on pre-interventional CT to isodense on postinterventional CT was seen in 37 patients in a total of 49 ASPECTS areas (Cohen's kappa 0.819; p < 0.001). In 17 patients, the previously hypoattenuated brain areas became isodense, but appeared swollen. In 20 patients (13%), the previously hypodense brain area could not be distinguished from normal brain parenchyma. On follow-up imaging, all isodense brain areas showed signs of infarction. Pseudo-normalization of infarct hypoattenuation on postinterventional CT is not infrequent. It is most likely caused by contrast leakage in infarcted parenchyma and does not represent salvage of ischemic brain parenchyma. (orig.)

  13. Review: Regional land subsidence accompanying groundwater extraction

    Science.gov (United States)

    Galloway, Devin L.; Burbey, Thomas J.

    2011-01-01

    The extraction of groundwater can generate land subsidence by causing the compaction of susceptible aquifer systems, typically unconsolidated alluvial or basin-fill aquifer systems comprising aquifers and aquitards. Various ground-based and remotely sensed methods are used to measure and map subsidence. Many areas of subsidence caused by groundwater pumping have been identified and monitored, and corrective measures to slow or halt subsidence have been devised. Two principal means are used to mitigate subsidence caused by groundwater withdrawal—reduction of groundwater withdrawal, and artificial recharge. Analysis and simulation of aquifer-system compaction follow from the basic relations between head, stress, compressibility, and groundwater flow and are addressed primarily using two approaches—one based on conventional groundwater flow theory and one based on linear poroelasticity theory. Research and development to improve the assessment and analysis of aquifer-system compaction, the accompanying subsidence and potential ground ruptures are needed in the topic areas of the hydromechanical behavior of aquitards, the role of horizontal deformation, the application of differential synthetic aperture radar interferometry, and the regional-scale simulation of coupled groundwater flow and aquifer-system deformation to support resource management and hazard mitigation measures.

    To validate a Spanish adaptation of the Mishel Uncertainty of Illness Scale for use with emergency-department (ED) patients and their accompanying relatives or friends (the UIS-ED). We first developed a version of the questionnaire for Spanish ED situations. Next we assessed the content validity index for each of its items, revised it, and reassessed its face validity to produce a second version, which we then piloted in 20 hospital ED patients. A third revised version was then validated in a population of 320 adults (160 patients and 160 accompanying persons) who attended the ED between November 2015 and September 2016. The 12-item UIS-ED (60 points) was administered by 2 nurses while the patients and accompanying persons were in the ED. We gathered sociodemographic and clinical data as well as the subjects' perception about the information they were given. The mean (SD) uncertainty score among patients was 29 (11) points. Accompanying persons had a mean score of 36 (13) points. Factorial analysis confirmed the instrument's construct validity, finding that both dimensions of the original Mishel scale (complexity and ambiguity) were present in 6 items each. Factorial analysis explained 60% of the total variance in the patient version and 67% of the variance in the version for accompanying persons. Reliability statistics were good, with Cronbach's α values ranging from 0.912 to 0.938. Split-half reliability statistics ranged from 0.901 to 0.933. Correlations were significant in the analysis of convergent validity. The UIS-ED questionnaire may prove to be a simple, valid, and reliable way for assessing uncertainty in patients and their accompanying friends or relatives attending Spanish EDs.

  16. Thermal expansion accompanying the glass-liquid transition and crystallization

    M. Q. Jiang

    2015-12-01

    Full Text Available We report the linear thermal expansion behaviors of a Zr-based (Vitreloy 1 bulk metallic glass in its as-cast, annealed and crystallized states. Accompanying the glass-liquid transition, the as-cast Vitreloy 1 shows a continuous decrease in the thermal expansivity, whereas the annealed glass shows a sudden increase. The crystallized Vitreloy 1 exhibits an almost unchanged thermal expansivity prior to its melting. Furthermore, it is demonstrated that the nucleation of crystalline phases can induce a significant thermal shrinkage of the supercooled liquid, but with the growth of these nuclei, the thermal expansion again dominates. These results are explained in the framework of the potential energy landscape, advocating that the configurational and vibrational contributions to the thermal expansion of the glass depend on both, structure and temperature.

    We report a 20-year-old man with temporal lobe epilepsy (TLE) accompanied by hereditary motor and sensory neuropathy (HMSN). He had experienced complex partial seizures (CPS), which started with a nausea-like feeling, followed by loss of consciousness and automatism, since he was 6 years old. The frequency of attacks was at first decreased by phenytoin. However, attacks increased again when he was 18 years old. On admission, neurological examination showed mild weakness of the toes, pes cavus, hammer toe and mildly impaired vibratory sensation in his legs. Ten people in four generations of his family showed a history of epilepsy in the autosomal dominant inheritance form. His younger sister and mother had a history of epilepsy accompanied with pes cavus, hammer toe, weakness of toe and finger extension and mildly impaired vibratory sensation as well. Direct sequencing of the glioma-inactivated leucine-rich gene (LGI1), in which several mutations were reported in patients with familial lateral temporal lobe epilepsy, showed no specific mutation in this family. On consecutive video-EEG monitoring, paroxysmal rhythmic activity was confirmed in his left fronto-temporal region when he showed automatism, and then a generalized slow burst activity was detected when he lost consciousness. For his seizures, TLE with secondary generalization was diagnosed. In the nerve conduction study, delayed nerve conduction, distal motor latency and decreased amplitudes of the compound muscle action potentials (CMAP) of bilateral peroneal nerves were observed, indicating the existence of mild axonal degeneration. Based on these data, we consider that this family to be a new phenotype of autosomal dominant TLE accompanied by motor and sensory neuropathy.

  19. Auroral pulsations and accompanying VLF emissions

    V. R. Tagirov

    Full Text Available Results of simultaneous TV observations of pulsating auroral patches and ELF-VLF-emissions in the morning sector carried out in Sodankylä (Finland on February 15, 1991 are presented. Auroral pulsating activity was typical having pulsating patches with characteristic periods of about 7 s. Narrow-band hiss emissions and chorus elements at intervals of 0.3–0.4 s formed the main ELF-VLF activity in the frequency range 1.0–2.5 kHz at the same time. The analysis of auroral images with time resolution of 0.04 s allowed perfectly separate analysis of spatial and temporal variations in the auroral luminosity. Mutual correspondence between the behaviour of the luminous auroral patches and the appearance of ELF noise type hiss emissions and VLF chorus trains was found in two intervals chosen for analysis. While the hiss emissions were associated with the appearance of luminosity inside a limited area close to the zenith, the structured VLF emissions were accompanied by rapid motion of luminosity inside the area. The spatial dimension of the pulsating area was about 45–50 km and luminosity propagated inside it with velocity of about 10–12 kms. We discuss a new approach to explain the 5–15 s auroral pulsation based on the theory of flowing cyclotron maser and relaxation characteristics of ionosphere.

    Full Text Available ABSTRACT OBJECTIVE Understand the quotidian relationships of accompanying family members in an environment of care, which are close to the metaphor of a tribe in hospital environment. METHODQualitative study with data gathered from semi-structured interviews and observations with 16 family members accompanying hospitalized individuals with dependence on self-care. Data were submitted to thematic analysis, and analyzed through the metaphor of "tribe" proposed by comprehensive sociology. RESULTS Family members build up social clusters around caring, where we find traits typical of tribes: emotional ambience; solidarity based on links of sympathy and mutual assistance; an affectual nebula in the process of interaction; a logic of fusion in tactile relations; and communion/religiosity in the process of connecting in a collective identity. CONCLUSION In the presence of tragedy, families build social clusters similar to tribes having care as a totem.

    The purpose of this study was to evaluate a procedure for measurement of specific airway resistance (sRaw) by whole body plethysmography in young awake children accompanied by an adult. sRaw was measured by a single-step procedure, omitting the measurement of the thoracic gas volume. The frequency...... dependency of sRaw was investigated and the accuracy of simulating body temperature, atmospheric pressure and saturation with water vapour (BTPS) conditions by electronic compensation was assessed. One hundred and thirty one children with asthma were studied. In 57 children (mean (SD) age 5.6 (1.8) yrs) who....... In conclusion, the use of electronic compensation for simulating body temperature, atmospheric pressure and saturation with water vapour introduces a bias that affects the accuracy of the estimate of specific airway resistance. Nevertheless, plethysmographic measurements with and without an accompanying adult...

    The radiation dose to accompanying nurses, relatives and other patients in a nuclear medicine department waiting room was assessed at 5 min intervals by observing the seating arrangement. The total radiation dose to each person was calculated, using fixed values of dose rate per 100 MBq activity for radionuclides, and applying the inverse square law. Radioactive decay and attenuation effects due to intervening persons were also taken into account. The median radiation doses to accompanying nurses, relatives and other patients were 2.3, 2.0 and 0.2 {mu}Sv with maximum values of 17, 33 and 5 {mu}Sv respectively. In all cases, the radiation dose received by patients was less than 0.2% of the radiation dose resulting from their own investigation. Also, the maximum radiation dose received by an accompanying norse or friend was less than 1% of their appropriate annual dose limit. Similar values were obtained with calculations based on a 15 min time interval. The radiation doses received by those in a nuclear medicine department waiting room are small, and separate waiting room facilities for radioactive patients are unnecessary. (author).

    To evaluate the incidence, quantity, and presentation of intra- and extraosseous edema accompanying benign and malignant primary bone lesions, the magnetic resonance (MR) studies of 63 consecutive patients with histologically proven primary bone tumors were reviewed. MR scans were assessed for the presence and quantity of marrow and soft tissue edema and correlated with preoperative findings, resected specimens and follow-up data. The signal intensity and enhancement of tumor and edema prior to and after intravenous administration (if any) of gadolinium-labled diethylene triamine pentaacetate (Gd-DTPA) was analyzed. Marrow edema was encountered adjacent to 8 of 39 maglinant tumors and 14 of 24 benign lesions. Soft tissue edema was found accompanying 28 of 39 malignancies and 10 of 24 benign disorders. On enhanced T1-weighted MR images tumor and edema were difficult to differentiate. Tumor inhomogeneity made this differentiation easier on T2-weighted sequences. In 36 patients the contrast medium Gd-DTPA was used. Edema was present in 27 of these patients and the respective enhancement of tumor and edema could be compared. Edema always enhanced homogeneously, and in most cases it enhanced to a similar degree as or more than tumor. Marrow and, more specifically, soft tissue edema is a frequent finding adjacent to primary bone tumors. The mere presence and quantity of marrow and soft tissue edema are unreliable indicators of the biologic potential of a lesion. Unenhanced MR scans cannot always differentiate between tumor and edema, but the administration of Gd-DTPA is of assistance in differentiating tumor from edema. Awareness of marrow and/or soft tissue edema adjacent to bone lesions is of importance because edema can be a pitfall in the diagnostic work-up and staging prior to biopsy or surgery. (orig.)

    The process of free b-quarks quarks creation in e + e - -annihilation at the Z 0 -peak is regarded. The hadronic accompaniment due to bremsstrahlung of such a process is analysed. The calculations for free bb-bar-pair production are made taking into account the energy losses on colour field. The distributions of leptons and free light quarks from weak decays of b-quark are shown. The probability to overlap of ionization signals of free light quark and charge hadron is estimated. The comparison with LEP experimental data allows to get a conclusion, that the existing experimental accuracy does not exclude the creation of free b-quarks in the Z 0 -decays. 17 refs.; 6 figs

    Several mutations, located mainly in the MSX1 homeodomain, have been identified in non-syndromic tooth agenesis predominantly affecting premolars and third molars. We identified a novel frameshift mutation of the highly conserved C-terminal domain of MSX1, known as Msx homology domain 6 (MH6), in a Japanese family with non-syndromic tooth agenesis. To investigate the importance of MH6 in tooth development, Msx1 was targeted in mice with CRISPR/Cas system. Although heterozygous MH6 disruption did not alter craniofacial development, homozygous mice exhibited agenesis of lower incisors with or without cleft palate at E16.5. In addition, agenesis of the upper third molars and the lower second and third molars were observed in 4-week-old mutant mice. Although the upper second molars were present, they were abnormally small. These results suggest that the C-terminal domain of MSX1 is important for tooth and palate development, and demonstrate that that CRISPR/Cas system can be used as a tool to assess causality of human disorders in vivo and to study the importance of conserved domains in genes.

    Joubert syndrome presents neonatal respiratory abnormalities and other clinical manifestations. Pathologically the patients show hypoplasia or agenesis of cerebellar vermis and other intracranial anomalies. Our purpose is to evaluate the clinical manifestations and MR findings of Joubert syndrome. Among the patient presenting with clinical stigmata of Joubert syndrome and agenesis of vermis on MR imaging, eight patients who did not satisfied the criteria of Dandy-Walker malformation, tectocerebellar dysraphia and rhombencephalosynapsis were selected. MR findings and clinical manifestation were analyzed. On MR imaging, agenesis of the cerebellar vermis (all cases), hypoplasia of the cerebellar peduncle (6 cases), fourth ventricular contour deformity (6 cases), tentorial elevation (4 caes), deformity of the lateral ventricles (4 cases), dysgenesis of the straight sinus (3 cases) were demonstrated. Other findings were abnormalities of corpus callosum (3 cases), falx anomalies (3 case), occipital encephalomeningocele (2 cases) and fluid collection in posterior cranial fossa (2 cases). Clinical manifestations were developmental delay (5 cases), abnormal eyeball movement (3 cases), hypotonia (2 cases), neonatal respiratory abnormality (2 cases), etc. Joubert syndrome showed various clinical manifestations and intracranial anomalies. MR imaging is an useful modality in detection of the cerebellar vermian agenesis and other anomalies of the patients

    The temporomandibular joint (TMJ) functions as a load-bearing diarthrodial joint during mastication, and its continuous use and stress can lead to degeneration over age. Using senescence-accelerated (SAMP8) mice that develop early osteoarthritis-like changes in synovial joints at high frequency, we analyzed possible molecular mechanisms of TMJ degeneration and tested whether and how malocclusion may accelerate it. Condylar articular cartilage in young SAMP8 mice displayed early-onset osteoarthritic changes that included reductions in superficial/chondroprogenitor cell number, proteoglycan/collagen content, and Indian hedgehog (Ihh)-expressing chondrocytes. Following malocclusion induced by tooth milling, the SAMP8 condyles became morphologically defective, displayed even lower proteoglycan levels, and underwent abnormal chondrocyte maturation compared with malocclusion-treated condyles in wild-type mice. Malocclusion also induced faster progression of pathologic changes with increasing age in SAMP8 condyles as indicated by decreased PCNA-positive proliferating chondroprogenitors and increased TUNEL-positive apoptotic cells. These changes were accompanied by steeper reductions in Ihh signaling and by expression of matrix metalloproteinase 13 at the chondro-osseous junction in SAMP8 articular cartilage. In sum, we show for the first time that precocious TMJ degeneration in SAMP8 mice is accompanied by--and possibly attributable to--altered Ihh signaling and that occlusal dysfunction accelerates progression toward degenerative TMJ disease in this model.

    In patients with sciatica due to a lumbar disc herniation, it is generally recommended to reserve surgical treatment for those who suffer from intolerable pain or those who demonstrate persistent symptoms after conservative management. Controversy exists about the necessity of early surgical intervention for those patients that have an additional motor deficit. The aim of this study was to compare the recovery of motor deficit among patients receiving early surgery to those receiving prolonged conservative treatment. Subgroup analysis of a randomized controlled trial. This subgroup analysis focuses on 150 (53%) of 283 patients with sciatica due to a lumbar disc herniation and whose symptoms at baseline (before randomization) were accompanied by a motor deficit. Motor deficit was assessed through manual muscle testing and graded according to the Medical Research Council (MRC) scale. In total, 150 patients with 6 to 12 weeks of sciatica due to a lumbar disc herniation and whose symptoms were accompanied by a moderate (MRC Grade 4) or severe (MRC Grade 3) motor deficit were randomly allocated to early surgery or prolonged conservative treatment. Repeated standardized neurologic examinations were performed at baseline and at 8, 26, and 52 weeks after randomization. This study was supported by a grant from the Netherlands Organization for Health Research and Development (ZonMW) and the Hoelen Foundation The Hague. Sciatica recovered among seven (10%) of the 70 patients assigned to early surgery before surgery could be performed, and of the 80 patients assigned to conservative treatment, 32 patients (40%) were treated surgically because of intolerable pain. Baseline severity of motor deficit was graded moderate in 84% of patients and severe in 16% of patients. Motor deficit recovered significantly faster among patients allocated to early surgery (p=.01), but the difference was no longer significant at 26 (p=.21) or 52 weeks (p=.92). At 1 year, complete recovery of motor

    To determine the prevalence of permanent tooth anomalies in patients attending the graduate orthodontic clinic at the State University of New York at Buffalo. Charts of 496 subjects (310 females and 186 males) met the inclusion criteria for this study. The mean ages were 16 years and 3 months for the combined gender sample that received orthodontic treatment in the graduate orthodontic clinic between 2007 and 2010. Full pretreatment records (intraoral photographs, digital study models, lateral cephalograms and panoramic radiographs) were used for the assessment. Charts were examined for these anomalies: agenesis, supernumerary, impaction and delayed tooth eruption. Subjects were categorized by gender and ethnicity. The percentages of the anomalies were assessed according to type of malocclusion, gender, race, location, tooth class and region in the dental arches. Sixty-four subjects (12.9%) had at least one occurrence of delayed eruption and impaction (DEI), followed by 47 subjects (9.5%) who had at least one occurrence of agenesis, and seven (1.4%) had a supernumerary condition. Approximately 80% of the subjects had no dental anomalies. The presence of more than one anomaly was observed in 61 subjects. Twelve subjects (2.4%) had both agenesis and DEI. Agenesis tended to be more common in class II malocclusions (p=0.012). The prevalence of permanent tooth anomalies was (20.4%). The percentage occurrence of DEI was the highest (12.9%) followed by dental agenesis (9.5%) and supernumerary teeth (1.4%) in the orthodontic patients at the State University of New York at Buffalo.

    The aims of this investigation were to evaluate associations between orthodontic space closure (including first premolar intrusion and canine extrusion for esthetic reasons) and periodontal tissue deterioration over a 10-year period in subjects with one or both missing maxillary lateral incisors and to investigate the occurrence of signs or symptoms of temporomandibular disorder (TMD). This was a retrospective cohort study comprising patients treated by the same orthodontist. The agenesis group included 26 consecutive adolescent and young adult patients (9 male, 17 female) treated with space closure. The control group consisted of 32 orthodontic patients (12 male, 20 female) with no missing teeth and no need for extractions. In the agenesis group, full-mouth probing pocket depths and bleeding on probing were recorded at six locations for each of 657 teeth (3942 periodontal sites). In the control group, comparative data were collected for the maxillary first molars, premolars, canines, and lateral incisors, a total of 264 teeth (1584 periodontal sites). Mobility and gingival recession were also evaluated. Patients in both groups completed questionnaires concerning symptoms related to TMD. The full-mouth assessments in the agenesis group generally demonstrated periodontally healthy conditions, with probing depths below 4 mm and few bleeding sites. Some slight recessions were found, mostly on molars and second premolars, and there was normal mobility of first premolars that substituted for canines. Comparisons between the agenesis and control groups showed no statistically significant differences for the maxillary teeth regarding increased pocket depth (≥ 4 mm) or increased mobility. Interproximal sites in the agenesis group showed less bleeding on probing than in the control group; this was statistically significant. Anterior teeth in the agenesis group did not show any more recession than in the controls. In addition, we observed no

    1986-01-01

    A 63-year-old man was admitted for headache and progressive drowsiness. In spite of negative results from cerebrospinal fluid (CSF) stains and cultures of tuberculosis and other bacteria, CSF findings and tuberculosis-positive sputum culture led to a tentative diagnosis of tuberculous meningitis. Symptoms and neurological test results both improved remarkably during antituberculous chemotherapy. Although the brain CT scan taken on admission showed no abnormal findings, one taken two months later revealed multiple high-density areas after enhancement with a contrast medium, suggesting multiple intracranial tuberculomas accompanied by tuberculous meningitis. The size of the multiple high-density areas gradually decreased during antituberculous chemotherapy. The CT scan can clearly locate lesions, detect complications, and evaluate the effects of treatment in patients with intracranial tuberculosis. (author)

  2. Evaluation of dose equivalent to the people accompanying patients in diagnostic radiology using MCNP4C Monte Carlo code

    Complete text of publication follows. Objective: X rays used in diagnostic radiology contribute a major share to population doses from man-made sources of radiation. In some branches of radiology, it is necessary that another person stay in the imaging room and immobilize the patient to carry out radiological operation. ICRP 70 recommends that this should be done by parents or accompanying nursing or ancillary personnel and not in any case by radiation workers. Methods: Dose measurements were made previously using standard methods employing LiF TLD-100 dosimeters. A TLD card was installed on the main trunk of the body of the accompanying people where the maximum dose was probable. In this research the general purpose Monte Carlo N-particle radiation transport computer code (MCNP4C) is used to calculate the equivalent dose to the people accompanying patients exposed to radiation scattered from the patient (Without protective clothing). To do the simulations, all components of the geometry are placed within an air-filled box. Two homogeneous water phantoms are used to simulate the patient and the accompanying person. The accompanying person leans against the table at one side of the patient. Finally in case of source specification, only the focus of the X-ray tube is modelled, i.e. as a standard MCNP point source emitting a cone of photons. Photon stopping material is used as a collimator model to reduce the circular cross section of the cone to a rectangle. The X-ray spectra to be used in the MCNP simulations are generated with spectrum generator software, taking the X-ray voltage and all filtration applied in the clinic as input parameters. These calculations are done for different patient sizes and for different radiological operations. Results: In case of TL dosimetry, for a group of 100 examinations, the dose equivalents ranged from 0.01 μsv to 0.13 msv with the average of 0.05 msv. The results are seen to be in close agreement with Monte Carlo simulations

    Although the number of employees on overseas assignments accompanied by their families has increased steadily, little is known about the effects of this experience on family functioning. Japanese families on family-accompanied assignments living in Hong Kong were compared with families living in Japan (consisting of 135 and 248 paired partners, respectively). Applying an ecological framework, family functioning was examined using the Feetham Family Functioning Survey-Japanese (FFFS-J). Japanese wives living in Hong Kong rated family functioning lower, particularly in the area of "relationship between family and family members." Between paired marital partners living in Hong Kong, the level of satisfaction in the area of "relationship between family and society" was significantly lower for wives than for husbands. This study provides application of the family ecological framework in families in a multicultural environment and identifies potential areas for family assessment and intervention that may of interest to health care professionals who care for families living away from their home countries.

    This thesis describes an experiment for the radiation-accompanied π 0 photoproduction on the proton int the energy range of the Δ resonance. With the detector system from Crystal Ball (672 NaI(Tl) crystals) and the TAPS forward wall (510 BaF 2 modules) and the space-angle covering of this arrangement of nearly 4π the reaction γp→pπ 0 γ' could be studied with high statistics; furthermore the use of a both linearly and circularly polarized photon beam allowed beside the study of unpolarized cross sections also the consideration of polarization observables like the photon asymmetry of the π 0 meson or the single-spin asymmetry of the photon γ'. The experiment described hera was performed with a real photon beam, which was produced via the bremsstrahlung of the MAMI electron beam with energies of E 0 =883 MeV respectively E 0 =570 MeV on a diamond respectively iron radiator. By the momentum determination in a magnetic spectrometer (Glasgow-Mainz-Tagger) and a coincidence analysis with the product detectors Crystal Ball and TAPS this photon beam was energy-marked and allowed by this together with the liquid-hydrogen target a precise knowledge of the incident side of the photoinduced reactions. For the study of the reaction γp→pπ 0 γ' all final-state particle were detected in the detector systems with their complete energy and momentum informations. With the data analysis described in this thesis about 27,000 events of the radiation-accompanied π 0 production could be reconstructed, from which in connection with a simulation of the detector and analysis efficiency energy and angular differential cross sections of the photon γ', the π 0 meson, as well as the proton were determined in each three intervals of the beam energy (ω=325..375 MeV, ω=375..425 MeV, and ω=425..475 MeV). In the energy range between 325 MeV and 475 MeV for the total cross section values of about 60 nb to 80 nb result. Additionally the photon asymmetry (linearly polarized photons

    Hypothyroidism is often accompanied with decline of kidney function, or inability to maintain electrolyte balance. These changes are usually overlooked in everyday practice. Early recognition of this association eliminates unnecessary diagnostic procedures that postpone the adequate treatment. Two patients with elevated serum creatinine levels due to primary autoimmune hypothyroidism, with complete recovery of creatinine clearance after thyroid hormone substitution therapy are presented. The first patient was a young male whose laboratory tests suggested acute renal failure, and the delicate clinical presentation of reduced thyroid function. The second patient was an elderly woman with a history of a long-term signs and symptoms attributed to ageing, including the deterioration of renal function, with consequently delayed diagnosis of hypothyroidism. Serum thyrotropin and thyroxin levels measurement should be done in all cases of renal failure with undefined renal desease, even if the typical clinical presentation of hypothyroidism is absent. Thyroid hormone assays sholud also be performed in all patients with chronic kidney disease whose kidney function is rapidly worsening.

    2000-01-01

    We present the results of MRI examinations in ten patients with documented Nijmegen breakage syndrome (NBS), aged 1.75-19 years. T1-, Proton-Density- and T2-weighted spin-echo sequences were performed in three planes. All patients showed microcephaly with decreased size of the frontal lobes and narrow frontal horns. In four patients agenesis of the posterior part of the corpus callosum was found, with colpocephaly and temporal horns dilatation. In one patient callosal hypoplasia was accompanied by abnormal cerebrospinal fluid spaces and wide cerebral cortex, suspicious of pachygyria. Sinusitis was present in all ten patients, as a result of primary immunodeficiency. As in ataxia teleangiectasia and other breakage syndromes, patients with NBS show an inherited susceptibility to malignancy and hypersensitivity to X- and γ-radiation. CT is therefore contraindicated in these patients and MRI should be the method of choice for diagnostic imaging. (orig.)

    Primary care physicians are frequently faced with the challenge of evaluating primary amenorrhea in adolescent girls. Approximately 15% of these women have abnormal genital examination, with Müllerian agenesis being the second most frequent cause. We report two cases of adolescents with Müllerian agenesis that presented to a tertiary adolescent medicine center with primary amenorrhea and the very rare sexual phenomenon of urethral coitus. The aim of this report is to emphasize the importance of performing a genital examination in girls who present with amenorrhea in the primary care setting, even if 'normal' vaginal sexual activity is assumed. A 19-year-old Caucasian and a 16-year-old Filipino girl presented to a tertiary adolescent medicine center with primary amenorrhea and a history of 'normal' vaginal coitus. Investigation revealed Müllerian agenesis in association with urethral coitus in both cases; neither patient suffered significant urethral damage to require urethra reconstruction. However, the first adolescent had recurrent pyelonephritis and renal scarring and the second had dysuria.To the best of our knowledge, Case 1 also represents the second reported case of pituitary prolactinoma in association with Müllerian agenesis. The first adolescent underwent a hernia repair and vaginoplasty, whereas the second had vaginal dilatations. Our cases highlight the need for careful assessment of the external genitalia and vagina patency in all girls with amenorrhea, even if they report 'normal' vaginal sexual activity. Early identification of anatomic disorders such as Müllerian agenesis, will allow provision of proper care according to the patient's needs and the existing abnormalities, and prevention of rare, unintentional but potentially physically and emotionally harmful, patterns of sexual intercourse.

    to evaluate morphological changes (intima-media thickness, IMT) of the carotid arteries in patients being treated for essential hypertension (EH), and to discover whether this abnormality can be detected in normotensive offspring of subjects with EH (familial trait, FT); and to investigate the interrelationship between IMT and accompanying risk factors. cross-sectional study. angiology department, university teaching hospital. the study encompassed 172 subjects, of whom 46 were treated hypertonics aged 40-55 (49) years, and 44 age matched, normotensive volunteers as controls. We also investigated 41 normotensives with FT for essential hypertension aged 20-30 (25) years and 41 age- and sex-matched controls without FT. the hypertensive subjects were being treated either with long-acting calcium-channel antagonists or ACE-inhibitors. using high resolution ultrasound, IMT of the carotid bifurcation and of the common carotid artery was measured. In the hypertensives, the mean IMT was greater than that in the controls (0.92 (0.10) mm vs 0.72 (0.07) mm; p<0.00005). The IMT was independently related to accompanying risk factors: a positive family history of hypertension, age of the patient, duration of EH and the level of systolic/diastolic blood pressure (BP), body mass index and total/LDL-cholesterol. In subjects with FT, IMT was also greater compared to the control group (0.60 (0.05) mm vs 0.55 (0.04) mm; p<0.00005). IMT was not related to BP values. In treated essential patients with the EH, the IMT was increased. Individuals with FT also had greater IMT in the absence of elevated BP. The IMT in hypertensives was related to accompanying risk factors, which could be pathogenetic determinants of EH and/or its complications.

    CT findings in primary low spinal fluid pressure syndrome were studied on the basis of 3 cases. Case 1 was a 43-year-old male with a complicated bilateral isodense subdural hematoma (SDH). Case 2 was a 45-year-old female with a complicated bilateral high dense SDH. Case 3 was a 36-year-old female discharged without any complications after spinal fluid pressure normalized. Slight downward displacement of the brain under low spinal fluid pressure was shown as the narrowing of a Sylvian fissures and infratentorial cisterns on CT. On the other hand, in this syndrome with a complicated bilateral isodense SDH, in addition to this finding, CT revealed distortion and narrowing of body lateral ventricles, which might be differential findings from this syndrome without complicated SDH. Under low spinal fluid pressure, bridging veins are more stretched by a downward displacement of the brain. And consequently they were easily injured and SDH was developed. (author).

    The aim of present study is to find the association of solar flares with coronal mass ejections (CMEs) accompanied by Deca-Hectometric (DH) type II radio burst for the period 1997-2014 (solar cycle 23 and ascending phase of solar cycle 24). We have used a statistical analysis and found that 10-20∘ latitudinal belt of northern region and 80-90∘ longitudinal belts of western region of the sun are more effective for flare-CME accompanied by DH type II radio burst events. M-class flares (52%) are in good association with the CMEs accompanied by DH type II radio burst. Further, we have calculated the flare position and found that most frequent flare site is at the center of the CME span. However, the occurrence probability of all flares is maximum outside the CME span. X-class flare associated CMEs have maximum speed than that of M, C, and B-class flare associated CMEs. We have also found a good correlation between flare position and central position angle of CMEs accompanied by DH type II radio burst.

    2003-01-01

    Lithium has been electrochemically intercalated from a 1:2 (v/v) mixed solution of ethylene carbonate (EC) and methylethyl carbonate (MEC) containing 1 M LiClO sub 4 into graphite, and the lithium isotope fractionation accompanying the intercalation was observed. The lighter isotope was preferentially fractionated into graphite. The single-stage lithium isotope separation factor ranged from 1.007 to 1.025 at 25 C and depended little on the mole ratio of lithium to carbon of the lithium-graphite intercalation compounds (Li-GIC) formed. The separation factor increased with the relative content of lithium. This dependence seems consistent with the existence of an equilibrium isotope effect between the solvated lithium ion in the EC/MEC electrolyte solution and the lithium in graphite, and with the formation of a solid electrolyte interfaces on graphite at the early stage of intercalation.

    A variety of subdural pathologies that may mimic hematomas are reported in the literature. We aimed to identify the atypical clinical and radiologic presentations of subdural masses that may mimic subdural hematomas. A systematic review of MEDLINE and Embase was conducted independently by 2 reviewers to identify articles describing subdural hematoma mimickers. We also present a patient from our institution with a subdural pathology mimicking a subdural hematoma. We analyzed patient clinical presentations, underlying pathologies, radiologic findings, and clinical outcomes. We included 43 articles totaling 48 patients. The mean ± SD patient age was 55.7 ± 16.8 years. Of the 45 cases describing patient history, 13 patients (27%) had a history of trauma. The underlying pathologies of the 48 subdural collections were 10 metastasis (21%), 14 lymphoma (29%), 7 sarcoma (15%), 4 infectious (8%), 4 autoimmune (8%), and 9 miscellaneous (19%). Findings on computed tomography (CT) scan were 18 hyperdense (41%), 11 hypodense (25%), 9 isodense (20%), 3 isodense/hyperdense (7%), and 3 hypodense/isodense (7%). Thirty-four patients (71%) were treated surgically; among these patients, 65% had symptom resolution. Neither the pathology (P = 0.337) nor the management strategy (P = 0.671) was correlated with improved functional outcomes. Identification of atypical history and radiologic features should prompt further diagnostic tests, including magnetic resonance imaging (MRI), to elucidate the proper diagnosis, given that certain pathologies may be managed nonsurgically. A subdural collection that is hyperdense on CT scan and hyperintense on T2-weighted MRI, along with a history of progressive headache with no trauma, may raise the suspicion of an atypical subdural pathology.

    2015-12-01

    Full Text Available Methylmalonicaciduia(MMAaccompanied with homocystinuria is a rare autosomal-recessive with congenital metabolic disorder of Vitamin B12. There are three subtypes, cblC, cblD, cblF, in which cblC is the most common one. The diagnostic tests are tandem mass spectrometry and gas chromatography-mass spectrometry. Tests for activity of enzyme in fibroblasts from skin, complementary assay and genetic analysis can be used to make the subtype clear. Early-onset patients, defined by onset of symptoms before the age of 1 year, may have severe ocular involvement, including visual loss, nystagmus, strabismus, retinopathy, maculopathy, optic atrophy, abnormal electroretinography. Late-onset patients, defined by onset of symptoms after the age of 4 year, rarely have ocular manifestations. The pathogenesis of the ophthalmic symptoms may be related to the high level of homocystine, oxidative stress and the abnormal development of nervous systems. The treatment for MMA accompanied with homocystinuria is mostly symptomatic based. Ophthalmic treatment is limited. Early supplement of methionine,GSH or other antioxidants may be helpful for retinopathy. There is no standard ophthalmological examination for those patients in China. It is critical to set up inter-departmental cooperation and early stage examination for the treatments and outcomes of the patients.

    This paper presents two cases of rectal cancer accompanied with radiation colitis. Case 1 was a 53-year-old woman, who had a history of undergoing radiation therapy for a uterine cervical cancer 11 years before. She was seen at the hospital because of constipation and pointed out a IIa-like lesion on the rectum by colonoscopy. Abdominoperineal resection was performed. The surgical specimen showed the IIa-like lesion on the rectum. Pathological findings revealed well-differentiated adenocarcinoma. Immunohistochemical staining of p53 showed positive cells in atrophic glands. Case 2 was a 62-year-old woman complaining of diarrhea. There was a previous history of receiving radiation therapy for a uterine cancer 20 years before. Colonoscopy showed a Borrmann type 2 cancer on the rectum. Abdominoperineal resection was performed. Histological findings revealed moderately differentiated adenocarcinoma invading to the propria muscle. The features of radiation colitis were observed around the cancer in the two cases which provided a clue to diagnose the lesions with radiation-induced cancer. (author)

  11. Acrolein and Human Disease: Untangling the Knotty Exposure Scenarios Accompanying Several Diverse Disorders.

    Acrolein is a highly toxic electrophile that participates in many diseases, yet efforts to delineate its precise mechanistic contributions to specific conditions are complicated by its wide distribution within human environments. This Perspective develops the proposal that due to its mixed status as environmental pollutant, metabolic byproduct, and endotoxicant which forms via ubiquitous pathophysiological processes, many diseases likely involve acrolein released from multiple sources. Although the category boundaries are indistinct, at least four identifiable exposure scenarios are identifiable. First, in some syndromes, such as those accompanying chronic or acute intoxication with smoke, whatever role acrolein plays in disease pathogenesis mainly traces to exogenous sources such as the combustion of tobacco or other organic matter. A second exposure category involves xenobiotics that undergo metabolism within the body to release acrolein. Still other health conditions, however, involve acrolein that forms via several endogenous pathways, some of which are activated upon intoxication with xenobiotics (i.e., Exposure Category 3), while still others accompany direct physical trauma to body tissues (Exposure Category 4). Further complicating efforts to clarify the role of endogenous acrolein in human disease is the likelihood that many such syndromes are complex phenomena that resemble "chemical mixture exposures" by involving multiple toxic substances simultaneously. This Perspective contends that while recent decades have witnessed much progress in describing the deleterious effects of acrolein at the cellular and molecular levels, more work is needed to define the contributions of different acrolein sources to "real-world" health conditions in human subjects.

    To clarify the clinical characteristics of definite and non-definite diagnosis groups in intracranial hypotension accompanied by trauma (IHAT), we undertook investigations of registered patients (n=23) prospectively. The results revealed the following features of IHAT: definite diagnosis group, 4 cases; they had long periods from injury to onset (5.5±5.7 days), but these were markedly shorter than in the non-definite group; 75% of definite cases showed typical postural headache; 75% of definite cases showed dural enhancement on Gd-MRI; all 4 cases had confirmed cerebrospinal fluid (CFS) leakage based on imaging diagnosis with cervical lesions in 2 cases and cervical-thoracic lesions in 2 cases; and 6) good recovery was achieved in them by conservative therapy and blood patch, with a cure rate of 100%. These findings suggest that confirmed CFS leakage is indispensable for reaching definite diagnosis of IHAT. (author)

    Highlights: •We investigated imaging findings on gadoxetic acid-enhanced MRI of HCCs without the typical enhancement pattern on multiphasic MDCT. •Most HCCs showed ancillary MR findings of typical HCC. •Considerable number of HCCs showed MR enhancement pattern of typical HCC. -- Abstract: Objective: The purpose of this study was to investigate the value of enhancement kinetics and ancillary imaging findings on gadoxetic acid-enhanced and diffusion-weighted (DW) MR imaging for diagnosing hepatocellular carcinomas (HCCs) without the typical enhancement pattern on contrast-enhanced multiphasic MDCT in patients with chronic liver disease. Materials and methods: Eighty-two surgically confirmed HCCs without the typical enhancement pattern (hypervascular in the arterial phase, followed by washout on the portal or equilibrium phases) on triple-phase MDCT were enrolled in this study. The patients were classified into four categories based on the CT density pattern of arterial and equilibrium phases (isodense–isodense, hypodense–hypodense, isodense–hypodense, and hyperdense–isodense) compared to liver parenchyma. Signal intensity of HCCs on T2-weighted images (T2WI), arterial phase, 3 min late-phase, hepatobiliary phase (HBP) and DW images with a b value of 800 s/mm 2 were qualitatively evaluated, and ADC values were measured. Fisher's exact test and Chi-square test were used to compare the frequency and trend of hyperintensity on T2WI, hypointensity on HBP images, hyperintensity on DW images, and histopathologic grades between groups with different CT density patterns. Kruskal–Wallis test was used to compare the ADC value between groups. Results: Thirty and 52 HCCs were categorized as hypervascular (hyperdense–isodense) and non-hypervascular HCCs (3, isodense–isodense; 37, hypodense–hypodense; 12, isodense–hypodense), respectively. Most HCCs showed hyperintensity on T2WI (77/82, 93.9%) and DW images (81/82, 98.8%) and hypointensity on HBP images

    In everyday acoustic scenes, figure-ground segregation typically requires one to group together sound elements over both time and frequency. Electroencephalogram was recorded while listeners detected repeating tonal complexes composed of a random set of pure tones within stimuli consisting of randomly varying tonal elements. The repeating pattern was perceived as a figure over the randomly changing background. It was found that detection performance improved both as the number of pure tones making up each repeated complex (figure coherence) increased, and as the number of repeated complexes (duration) increased - i.e., detection was easier when either the spectral or temporal structure of the figure was enhanced. Figure detection was accompanied by the elicitation of the object related negativity (ORN) and the P400 event-related potentials (ERPs), which have been previously shown to be evoked by the presence of two concurrent sounds. Both ERP components had generators within and outside of auditory cortex. The amplitudes of the ORN and the P400 increased with both figure coherence and figure duration. However, only the P400 amplitude correlated with detection performance. These results suggest that 1) the ORN and P400 reflect processes involved in detecting the emergence of a new auditory object in the presence of other concurrent auditory objects; 2) the ORN corresponds to the likelihood of the presence of two or more concurrent sound objects, whereas the P400 reflects the perceptual recognition of the presence of multiple auditory objects and/or preparation for reporting the detection of a target object.

    PDAC (also termed Matthew Wood) syndrome is a rare, autosomal recessive disorder characterized by pulmonary hypoplasia/aplasia, diaphragmatic defects, bilateral anophthalmia, and cardiac malformations. The disorder is caused by mutations in STRA6, an important regulator of vitamin A and retinoic acid metabolism. We describe six cases from four families of Hmong ancestry, seen over a 30 years period in California. These include: (i) consanguineous siblings with a combination of bilateral anophthalmia, diaphragmatic abnormalities, truncus arteriosus, and/or pulmonary agenesis/hypoplasia; (ii) a singleton fetus with bilateral anophthalmia, pulmonary agenesis, cardiac malformation, and renal hypoplasia; (iii) a sibling pair with a combination of antenatal contractures, camptodactyly, fused palpebral fissures, pulmonary agenesis, and/or truncus arteriosus; (iv) a fetus with bilateral anophthalmia, bushy eyebrows, pulmonary agenesis, heart malformation, and abnormal hand positioning. The phenotypic spectrum of PDAC syndrome has until now not included contractures or camptodactyly. Sequencing of STRA6 in unrelated members of families three and four identified a novel, shared homozygous splice site alteration (c.113 + 3_4delAA) that is predicted to be pathogenic. We hypothesize this may represent a unique disease allele in the Hmong. We also provide a focused review of all published PDAC syndrome cases with confirmed or inferred STRA6 mutations, illustrating the phenotypic and molecular variability that characterizes this disorder. © 2015 Wiley Periodicals, Inc.

    Mutations inTFAP2B has been reported in patients with isolated patent ductus arteriosus (PDA) and Char syndrome. We performed mutation analysis of TFAP2B in 43 patients with isolated PDA, 7 patients with PDA with other congenital heart defects and 286 patients with isolated tooth agenesis with or without other dental anomalies. The heterozygous c.1006G>A mutation was identified in 20 individuals. Those mutation carriers consisted of 1 patient with term PDA (1/43), 16 patients with isolated tooth agenesis with or without other dental anomalies (16/286; 5.6%), 1 patient with PDA and severe valvular aortic stenosis and tooth agenesis (1/4) and 2 normal controls (2/100; 1%). The mutation is predicted to cause an amino-acid substitution p.Val336Ile in the TFAP2B protein. Tfap2b expression during early mouse tooth development supports the association of TFAP2B mutation and dental anomalies. It is hypothesized that this incidence might have been the result of founder effect. Here we report for the first time that TFAP2B mutation is associated with tooth agenesis, microdontia, supernumerary tooth and root maldevelopment. In addition, we also found that TFAP2B mutations, the common causes of PDA in Caucasian, are not the common cause of PDA in Thai population.

    Full Text Available Crytomenorrhea arises usually due to the imperforate hymen, sometimes due to vaginal septum, rarely due to cervical agenesis. Here, we present a case of primary amenorrhea resulting from cervical agenesis in a 38-year-old woman. She presented with primary amenorrhea and cyclic lower abdominal pain. She had undergone some surgery 5 years back, details of which were not available. On examination secondary sexual characters were normal, per abdomen there was an 18 weeks size firm abdominopelvic mass. Local vaginal examination showed a blind vaginal pouch. A clinical diagnosis of hematometra due to transverse vaginal septum was made. However, magnetic resonance imaging pelvis suggested hematometra with cervical stenosis. The patient was taken up for examination under anaesthesia (EUA and exploratory laparotomy. On opening the abdomen uterus found to be enlarged with dense adhesions all around and signs of endometriosis. Extensive adhesiolysis revealed bilateral chocolate cysts of ovaries with hematosalpinges and peritubal adhesions. Hysterotomy and drainage of tarry contents were followed by an exploration of the uterine cavity. The lower pole ended blindly with no evidence of any cervix. Peroperative diagnosis of cervical agenesis leading to hematometra and endometriosis was made. A subtotal hysterectomy with bilateral salpingo-oophorectomy was done. Histopathological examination confirmed ovarian endometriosis and adenomyosis of uterus. Though reconstructive surgery for cervical dysgenesis has been successful in some cases, hysterectomy is generally recommended for cervical agenesis.

    Full Text Available In this paper, learning to sing with the accompaniment of the gusle is reconsidered within the concept of the preservation of traditional folk music as an intangible cultural heritage, that is, as a specific form of music education. Having dealt with a traditional way of providing continuity in the practice of guslars` (i. e. gusle players - which is learning by observing and imitating more experienced family members or guslars from nearby surrounding - some crucial moments in the history of singing with the accompaniment of the gusle, which also influenced the process of transmitting this skill, are demonstrated. In recent times, singing with the accompaniment of the gusle has been mastered not only within family circles but also in associations of guslars, at private schools of music, and lately there has also been an opportunity to learn this skill at some state schools of music. Accordingly, interviews with the members of an Association of guslars association that is particularly distinguished by the fostering young guslars, and interviews with gusle teachers and pupils who attend schools of music were used as primary sources for this paper, together with the specific experience of the author as a president of the jury in a young guslars’ competition. Since the poetic content of the songs is primarily learnt from printed collections or audio recordings, future guslars in fact master the musical skills of playing and singing along the instrument, that is, the skill of the vocal interpretation of a chosen written poetic text. Concerning these, some programmes and methods are discussed, as well as their effects on young guslars’ competence, principally from the point of style and aesthetics. Attention is particularly drawn to flaws in the teaching concept of future gusle players at state schools of music. In conclusion, the necessity of applying ethnomusicological findings to activities concerning the preservation of an intangible cultural

    2017-01-01

    Full Text Available The thermal modelling of the Friction Stir Welding process allows for better recognition and understanding of phenomena occurring during the joining process of different materials. It is of particular importance considering the possibilities of process technology parameters, optimization and the mechanical properties of the joint. This work demonstrates the numerical modelling of temperature distribution accompanying the process of friction stir welding. The axisymmetric problem described by Fourier’s type equation with internal heat source is considered. In order to solve the diffusive initial value problem a fully implicit scheme of the finite difference method is applied. The example under consideration deals with the friction stir welding of a plate (0.7 cm thick made of Al 6082-T6 by use of a tool made of tungsten alloy, whereas the material subjected to welding was TiC powder. Obtained results confirm both quantitatively and qualitatively experimental observations that the superior temperature corresponds to the zone where the pin joints the shoulder.

    2012-09-01

    Adolescence is a relatively short period between childhood and adulthood. It is very difficult to determine adulthood based on biological indicators. The third molar may be considered a potential age marker for the period between the ages of 16-21. Our study evaluated a set of 1700 panoramic radiographs of individuals aged between 5 and 21 years. Results confirmed the statistically significant difference in the course of third molars development. The mean deviation for individuals with one third molar agenesis is -0.98 years, for individuals with two third molars agenesis -1.89 years, and with three molars agenesis -3.28 years. Thus, the extent of the deviation is directly proportional to the number of unformed third molars. The calculation of age according to the mean of stages of all third molars could lead to the underestimation of age. No intergender differences were found. Age determination using third molars could be used for forensic purposes. © 2012 American Academy of Forensic Sciences.

    Common uterine anomalies are important owing to their impact on fertility, and complex mesonephric anomalies and certain Müllerian malformations are particularly important because they cause serious clinical symptoms and affect woman's quality of life, in addition to creating fertility problems. In these cases of complex female genital tract malformations, a correct diagnosis is essential to avoid inappropriate and/or unnecessary surgery. Therefore, acquiring and applying the appropriate embryological knowledge, management and therapy is a challenge for gynaecologists. Here, we considered complex malformations to be obstructive anomalies and/or those associated with cloacal and urogenital sinus anomalies, urinary and/or extragenital anomalies, or other clinical implications or symptoms creating a difficult differential diagnosis. A diligent and comprehensive search of PubMed and Scopus was performed for all studies published from 1 January 2011 to 15 April 2015 (then updated up to September 2015) using the following search terms: 'management' in combination with either 'female genital malformations' or 'female genital tract anomalies' or 'Müllerian anomalies'. The MeSH terms 'renal agenesis', 'hydrocolpos', 'obstructed hemivagina' 'cervicovaginal agenesis or atresia', 'vaginal agenesis or atresia', 'Herlyn-Werner-Wunderlich syndrome', 'uterine duplication' and 'cloacal anomalies' were also used to compile a list of all publications containing these terms since 2011. The basic embryological considerations for understanding female genitourinary malformations were also revealed. Based on our experience and the updated literature review, we studied the definition and classification of the complex malformations, and we analysed the clinical presentation and different therapeutic strategies for each anomaly, including the embryological and clinical classification of female genitourinary malformations. From 755 search retrieved references, 230 articles were analysed and

    The presence of two or more epileptogenic pathologies in patients with epilepsy is often observed, and the coexistence of focal cortical dysplasia (FCD) with hippocampal sclerosis (HS) is one of the most frequent clinical presentations. Although surgical resection has been an important treatment for patients with refractory epilepsy associated with FCD, there are few studies on the surgical treatment of FCD accompanied by HS, and treatment by resection of both neocortical dysplastic tissue and hippocampus is still controversial. We retrospectively recruited epilepsy patients who had undergone surgical treatment for refractory epilepsy with the pathologic diagnosis of FCD and the radiologic evidence of HS. We evaluated the prognostic roles of clinical factors, various diagnostic modalities, surgical procedures, and the severity of pathology. A total of 40 patients were included, and only 35.0% of patients became seizure free. Complete resection of the epileptogenic area (p = 0.02), and the presence of dysmorphic neurons or balloon cells on histopathology (p = 0.01) were associated with favorable surgical outcomes. Patients who underwent hippocampal resection were more likely to have a favorable surgical outcome (p = 0.02). We show that patients with complete resection of epileptogenic area, the presence of dysmorphic neurons or balloon cells on histopathology, or resection of hippocampus have a higher chance of a favorable surgical outcome. We believe that this observation is useful in planning of surgical procedures and predicting the prognoses of individual patients with FCD patients accompanied by HS.

    Full Text Available Oleg Negruţa’s composition repertoire for solo instruments with accompaniment, of which clarinet opuses are highlighted, is important for indigenous musical art. In a vast genre complex, it confirms the composer’s constant commitment to the idea of the Bessarabian professional school. In this sense, as relevant works can be considered the three pieces for clarinet and piano: Improvisation, Fantasy on a Theme by Paganini and Elegy. However, this article is meant to offer details in an analytical way about Negruţa’s specific language and, moreover, to emphasize the author’s mastery of combining folklore elements with others characteristic ofjazz, both being treated according to the canons of academic music.

    The authors report the findings of Aicardi syndrome, a disease of unknown etiology composed of multiple spasms, chorioretinal lacunae and agenesis of the corpus callosum. They present a case of Aicardi syndrome with characteristic clinical presentation and magnetic resonance imaging findings. The disease, despite being considered rare, has characteristic imaging findings. Over the past years magnetic resonance imaging has improved its ability in demonstrating other findings besides agenesis of the corpus callosum, making the radiologist's role very important in the diagnostic suspicion of this disease.

    Over the last years, growing resistance of gonorrhea to quinolones has emerged worldwide. Currently, cases with resistance to oral and parenteral third-generation cephalosporins are increasingly reported. Because gonorrhea is not a notifiable infection in Germany, data on epidemiology and antimicrobial surveillance of gonorrhea are scarce. We present the results of N. gonorrhoea testing at the University Hospital Dresden over the course of ten years. The results of cultural and nucleic acid amplification testing of gonorrhea and accompanying infections of 1,850 smears between 2001 and 2010 were analyzed retrospectively. Among 181 patients (mean age 30.4 years) 159 had positive PCR analyses for gonorrhea and 50 positive cultures of Neisseria gonorrhoea. The rate of ciprofloxacin resistance was high (in 46% of all isolates), primarily in men. Resistance to cefotaxime and ceftriaxone could not be detected so far. In 40% of the cases at least one accompanying urogenital infection occurred, predominantly with Chlamydia trachomatis. Similar to other regions of Germany, a high percentage of resistance to quinolones was found in gonorrhea, but not to cephalosporins. Additionally, accompanying infections were frequent and warrant screening. In the light of recent cases of resistance to cephalosporins currently emerging in Europe, cultural diagnosis of gonorrhea should definitely be intensified by all means. The results should be integrated into a surveillance system. © The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

    2018-04-01

    Thermal density fluctuations of supercritical CO2 were explored using small-angle neutron scattering (SANS), whose amplitude (susceptibility) and correlation length show the expected maximum at the Widom line. At low pressure, the susceptibility is in excellent agreement with the evaluated values on the basis of mass density measurements. At about 20 bar beyond the Widom line, SANS shows the formation of droplets accompanied by an enhanced number density of the supercritical fluid. The corresponding borderline is interpreted as a Frenkel line separating gas- and liquidlike regimes.

    Macular serous retinal detachment (MSRD) is a rare complication in highly myopic patients with an inferior staphyloma, tilted disc, or dome-shaped macula. Multiple evanescent white dot syndrome (MEWDS) presents with sudden visual loss and multiple yellowish dots that resolve spontaneously within several weeks. The authors report the development and spontaneous resolution of subretinal fluid accompanied by MEWDS in a myopic patient with a dome-shaped macula. Dysfunction of the retinal pigment epithelium due to MEWDS likely induced temporary MSRD in this patient. Copyright 2014, SLACK Incorporated.

    The evolution of extratropical transient waves as they propagate eastward from the Eurasian land mass toward the Pacific during selected cold surge events in the winter Monsoon Experiment (MONEX) is studied. The outstanding cold surge episodes during MONEX are first identified, and the salient synoptic features related to these events are described using composite streamline charts. The structure of rapidly varying disturbances accompanying the cold surges and the associated energetics are examined, and the behavior of those fluctuations over relatively longer time scales is addressed.

    Differentiating autism spectrum disorders (ASDs) without accompanying intellectual impairment from personality disorders is often challenging. Identifying personality traits and personality pathology specific to ASD might facilitate diagnostic procedure. We recruited a sample of 59 adults with ASD without accompanying intellectual impairment, 62 individuals with narcissistic personality disorder, 80 individuals with borderline personality disorder, and 106 nonclinical controls. Personality traits, measured with the neo-personality inventory-revised (NEO-PI-R), and personality pathology, measured with the dimensional assessment of personality pathology (DAPP-BQ), were assessed. Personality traits and personality pathology specific to ASD could be identified. ASD individuals scored significantly lower on the NEO-PI-R scales extraversion and openness to experience and significantly higher on the DAPP-BQ scales inhibitedness and compulsivity relative to all other groups. Diagnostic implications are discussed.

    2008-08-01

    To evaluate the readability and related features of English language Quick Reference Guides (QRGs) and User Manuals (UMs) accompanying home blood pressure monitors (HBPMs). We evaluated QRGs and UMs for 22 HBPMs [arm (n=12); wrist (n=10)]. Using established criteria, we evaluated reading grade level, language availability, dimensions, text point size, use of illustrations, layout/formatting characteristics, and emphasis of key points of English-language patient instructions accompanying HBPMs. Readability was calculated using McLaughlin's Simplified Measure of Gobbledygoop. Items from the Suitability of Materials Assessment and User-Friendliness Tool were used to assess various layout features. Simplified Measure of Gobbledygoop scores of both QRGs (mean+/-SD=9.1+/-0.8) and UMs (9.3+/-0.8) ranged from 8th to 10th grade. QRGs and UMs presented steps in chronological order, used active voice throughout, avoided use of specialty fonts, focused on need to know, and used realistic illustrations. Seven sets of instructions included all seven key points related to proper HPBM use, whereas three sets of instructions included less than or equal to three key points (mean=4.8+/-1.9). Although most QRGs and UMs met at least some recommended low-literacy formatting guidelines, all instructional materials should be developed and tested to meet the needs of the patient population at large. Key points related to proper HBPM use should not only be included within these instructions, but highlighted to emphasize their importance.

    We studied nine children with posterior cranial fossa ependymomas to identify specific neuroradiological features. Patients were studied preoperatively with CT and MRI; T1-, T2- and proton-density (PD)-weighted images were obtained. All children underwent surgery and a definite histopathological diagnosis was made. All the tumours grew into the fourth ventricle and caused dilatation of its upper part, which resembled a cap. All but one were separated from the vermis by a cleavage plane. In eight cases there was desmoplastic development through the foramina of the fourth ventricle, and five were heterogeneous due to necrosis and cystic change; one had a haemorrhagic area. In most cases the solid portion was isointense with grey matter on T1-weighted images, hyperintense on PD weighting, and isointense on T2-weighted images. On CT the tumour was isodense in six cases and calcification was detected in four. The presence of both desmoplastic development and a tumour/vermis cleavage plane in a posterior cranial fossa tumour isodense on CT is highly suggestive of ependymoma. (orig.)

    Full Text Available Agenesis of the corpus callosum (ACC, cerebellar hypoplasia (CBLH, and polymicrogyria (PMG are severe congenital brain malformations with largely undiscovered causes. We conducted a large-scale chromosomal copy number variation (CNV discovery effort in 255 ACC, 220 CBLH, and 147 PMG patients, and 2,349 controls. Compared to controls, significantly more ACC, but unexpectedly not CBLH or PMG patients, had rare genic CNVs over one megabase (p = 1.48×10⁻³; odds ratio [OR] = 3.19; 95% confidence interval [CI] = 1.89-5.39. Rare genic CNVs were those that impacted at least one gene in less than 1% of the combined population of patients and controls. Compared to controls, significantly more ACC but not CBLH or PMG patients had rare CNVs impacting over 20 genes (p = 0.01; OR = 2.95; 95% CI = 1.69-5.18. Independent qPCR confirmation showed that 9.4% of ACC patients had de novo CNVs. These, in comparison to inherited CNVs, preferentially overlapped de novo CNVs previously observed in patients with autism spectrum disorders (p = 3.06×10⁻⁴; OR = 7.55; 95% CI = 2.40-23.72. Interestingly, numerous reports have shown a reduced corpus callosum area in autistic patients, and diminished social and executive function in many ACC patients. We also confirmed and refined previously known CNVs, including significantly narrowing the 8p23.1-p11.1 duplication present in 2% of our current ACC cohort. We found six novel CNVs, each in a single patient, that are likely deleterious: deletions of 1p31.3-p31.1, 1q31.2-q31.3, 5q23.1, and 15q11.2-q13.1; and duplications of 2q11.2-q13 and 11p14.3-p14.2. One ACC patient with microcephaly had a paternally inherited deletion of 16p13.11 that included NDE1. Exome sequencing identified a recessive maternally inherited nonsense mutation in the non-deleted allele of NDE1, revealing the complexity of ACC genetics. This is the first systematic study of CNVs in congenital brain malformations, and

    The purpose of this clinical study was to describe outcome variables of all-ceramic and metal-ceramic implant-supported, single-tooth restorations. A total of 59 patients (mean age: 27.9 years) with tooth agenesis and treated with 98 implant-supported single-tooth restorations were included in this study. Two patients did not attend baseline examination, but all patients were followed for 3 years. The implants supported 52 zirconia, 21 titanium and 25 gold alloy abutments, which retained 64 all-ceramic and 34 metal-ceramic crowns. At baseline and 3-year follow-up examinations, the biological outcome variables such as survival rate of implants, marginal bone level, modified Plaque Index (mPlI), modified Sulcus Bleeding Index (mBI) and biological complications were registered. The technical outcome variables included abutment and crown survival rate, marginal adaptation of crowns, cement excess and technical complications. The aesthetic outcome was assessed by using the Copenhagen Index Score, and the patient-reported outcomes were recorded using the OHIP-49 questionnaire. The statistical analyses were mainly performed by using mixed model of ANOVA for quantitative data and PROC NLMIXED for ordinal categorical data. The 3-year survival rate was 100% for implants and 97% for abutments and crowns. Significantly more marginal bone loss was registered at gold-alloy compared to zirconia abutments (P = 0.040). The mPlI and mBI were not significantly different at three abutment materials. The frequency of biological complications was higher at restorations with all-ceramic restorations than metal-ceramic crowns. Loss of retention, which was only observed at metal-ceramic crowns, was the most frequent technical complication, and the marginal adaptations of all-ceramic crowns were significantly less optimal than metal-ceramic crowns (P = 0.020). The professional-reported aesthetic outcome demonstrated significantly superior colour match of all-ceramic over metal

    Chronic inflammation in the substantia nigra (SN) accompanies conditions with progressive neurodegeneration. This inflammatory process contributes to gradual iron deposition that may catalyze formation of free-radical mediated damage, hence exacerbating the neurodegeneration. This study examined proteins related to iron-storage (ferritin) and iron-export (ferroportin) (aka metal transporter protein 1, MTP1) in a model of neurodegeneration. Ibotenic acid injected stereotactically into the striatum leads to loss of GABAergic neurons projecting to SN pars reticulata (SNpr), which subsequently leads to excitotoxicity in the SNpr as neurons here become vulnerable to their additional glutamatergic projections from the subthalamic nucleus. This imbalance between glutamate and GABA eventually led to progressive shrinkage of the SNpr and neuronal loss. Neuronal cell death was accompanied by chronic inflammation as revealed by the presence of cells expressing ED1 and CD11b in the SNpr and the adjacent white matter mainly denoted by the crus cerebri. The SNpr also exhibited changes in iron metabolism seen as a marked accumulation of inflammatory cells containing ferric iron and ferritin with morphology corresponding to macrophages and microglia. Ferritin was detected in neurons of the lesioned SNpr in contrast to the non-injected side. Compared to non-injected rats, surviving neurons of the SNpr expressed ferroportin at unchanged level. Analyses of dissected SNpr using RT-qPCR showed a rise in ferritin-H and -L transcripts with increasing age but no change was observed in the lesioned side compared to the non-lesioned side, indicating that the increased expression of ferritin in the lesioned side occurred at the post-transcriptional level. Hepcidin transcripts were higher in the lesioned side in contrast to ferroportin mRNA that remained unaltered. The continuous entry of iron-containing inflammatory cells into the degenerating SNpr and their subsequent demise is probably

    To observe the effects of comprehensive therapy on serum secreted protein acidic and rich in cysteine (SPARC) levels in ankylosing spondylitis (AS) patients accompanied with osteoporosis (OP), and to explore the possible mechanisms for SPARC in AS patients accompanied with osteoporosis. Totally 48 AS patients accompanied with OP (Group A) were treated with massage, intravenous infusion of Cervus and Cucumis Polypeptide Injection, and Bushen Quhan Zhiwang Decoction (BQZD) for 3 months. At the same time, 45 normal healthy subjects were recruited as the normal control group (Group B). Serum SPARC levels were measured by ELISA in Group A before and after comprehensive therapy and in those of Group B. The levels of bone mineral density of femoral neck (FN BMD), bone mineral density of 2 -4 lumbar spine (L2-4 BMD), bone specific alkaline phosphatase (BSAP), tumor necrosis factor alpha (TNF-alpha), and transforming growth factor beta-1 (TGF-beta1) were detected. Meanwhile, Bath AS disease activity index (BASDAI) and Bath AS functional index (BASFI) were detected in Group A before and after treatment. The correlations between the aforesaid indices and serum SPARC levels were analyzed. Serum SPARC levels were significantly lower in those of Group A than in those of Group B (175. 30 +/- 72.04 micro/L vs 190. 52 +/- 86. 13 microg/ L, P <0. 01). Serum SPARC levels in those of Group A were negatively correlated with TNF-alpha (r = -0.261, P <0.01), positively with L2-4 BMD, TGF-beta1, and BSAP (r =0.437,0.256, 0.385, P <0.05, P <0.01). L2-4BMD and BSAP were independently predictors of serum SPARC in patients of Group A. After comprehensive therapy, the levels of TNF-alpha, BASDAI, and BASFI obviously decreased, TGF-beta1, BSAP, L2-4 BMD, and FN BMD obviously increased (P <0. 05, P <0. 01). The serum SPARC levels also significantly increased (188.32 +/- 87.50 microg/L, P <0. 05). Comprehensive therapy could effectively improve the bone metabolism, clinical symptoms and the

    An unusual anatomic configuration of segmental tracheal agenesis/atresia with esophageal duplication on autopsy in a fetus that demised in utero at 29 weeks is reported. The mother was scanned initially for a cardiac anomaly at 20 weeks and on follow-up scan at 27 weeks had polyhydramnios and underwent amnioreduction. The final autopsy diagnosis was vertebral, ano-rectal, cardiac, tracheoesophageal, renal, and limb malformations (VACTERL). We discuss the autopsy findings along with the embryological mechanisms and compare the configuration with Floyd's classification for tracheal agenesis. The difficulties in prenatal diagnosis are discussed.

    IgG4-related disease (IgG4-RD) is a systemic disease that affects multiple organs and generates nodules or thickening. Discriminating these diseases from malignancy is important because glucocorticoid treatment is effective for patients with IgG4-RD. Coexistence of IgG4-RD with various malignant diseases has been reported, but there are few reports with regard to gynecologic malignant diseases. We encountered a case of invasive cervical cancer stage IIB accompanied by IgG4-RD. The patient was a 46-year-old woman. On pelvic magnetic resonance imaging, fluorodeoxyglucose-positron emission tomography and computed tomography, systemic multiple lymph node swelling was seen, including in the neck and the mediastinum in addition to uterine cervix. Diagnosis (and hence, appropriate treatment choice) was achieved on pathology of the submandibular gland and uterus, and analysis of serum IgG4. IgG4-RD should be suspected in patients presenting with malignancy and unusual multiple lymph node swelling. © 2016 Japan Society of Obstetrics and Gynecology.

    Full Text Available Purpose. To determine the efficacy of intravitreal ranibizumab injection as adjuvant therapy in the treatment of neovascular glaucoma (NVG accompanied by postvitrectomy diabetic vitreous hemorrhage (PDVH. Methods. Eighteen NVG patients (18 eyes accompanied by PDVH were enrolled in this prospective, monocenter, 12-month, interventional case series. The consecutive 18 patients with an IOP ≥ 25 mmHg despite being treated with the maximum medical therapy were treated with intravitreal ranibizumab injections. Vitreous surgery or/with Ahmed valve implantation were indicated if no clinical improvement in vitreous haemorrhage and uncontrolled IOP was shown. Results. Ten patients got clear vitreous and controlled IOP only with 2.7±1.8 injections of ranibizumab without additional surgery. Vitrectomy or/with Ahmed valve implantation was administered in the other 8 eyes due to uncontrolled VH and IOP. At follow-up month 12, all the 18 eyes gained clear vitreous. At month 12 BCVA improved significantly compared to baseline. The baseline and follow-up at month 12 IOP/medication usage were 36.7±8.1 mmHg on 3.4±0.7 medications and 16.2±4.9 mmHg on 0.67±0.77 medications, respectively. Conclusions. The findings suggest that intravitreal ranibizumab injection as adjuvant therapy for treatment of NVG accompanied by PDVH may be safe and potentially effective. This clinical trial is registered with NCT02647515.

    Full Text Available Fanconi syndrome (FS is a rare condition that is characterized by defects in the proximal tubular function. A 48-year-old woman was admitted for evaluation of proteinuria. The patient showed normal anion gap acidosis, normoglycemic glycosuria, hypophosphatemia, and hypouricemia. Thus, her condition was compatible with FS. The M peak was found behind the beta globulin region in urine protein electrophoresis. Upon bone marrow examination, we found that 24% of cells were CD138+ plasma cells with kappa restriction. From a kidney biopsy, we found crystalline inclusions within proximal tubular epithelial cells. Thereafter, she was diagnosed with FS accompanied by multiple myeloma. The patient received chemotherapy and autologous stem cell transplantation, and obtained very good partial hematologic response. However, proximal tubular dysfunction was persistent until 1 year after autologous stem cell transplantation. In short, we report a case of FS accompanied by multiple myeloma, demonstrating crystalline inclusion in proximal tubular cells on kidney biopsy.

    Objective: Penetrating heart injury is potentially a life threatening condition due to cardiac tamponade or exsanguinating hemorrhage. The aim of this study was to evaluate victims who were referred to our hospital with penetrating heart and accompanying lung injuries and to review our overall outcome with this type of combined injuries. Methodology: Twenty patients with combined penetrating heart and lung injuries were operated at Yuzuncu Yil University Research Hospital, between May 1999 and January 2010. The diagnosis of combined heart and lung injuries was proved by surgical exploration in all cases. The surgical procedures mainly included the relief of cardiac tamponade, control of bleeding, repair of cardiac and pulmonary lacerations, and coronary artery bypass grafting if required. Results: In this series of 20 patients; there were 18 males and two females between the age of 14 to 60 years, with a mean age of 34.8+-13.5 years. Seventeen victims sustained stab wounds, and the remaining three were injured by a gunshot wounds. In 20 patients there were 22 cardiac chamber injuries. The most commonly injured cardiac chamber was the right ventricle followed by the left ventricle. In addition to the injuries to heart muscle, injuries to the coronary arteries were found in two patients. The most commonly injured lung lobe was the left upper lobe. Conclusion: Our experience shows that early diagnosis and immediate surgical intervention are the main factors affecting patient survival after penetrating heart and lung injuries. Therefore, heart injury should always be kept in mind in victims with penetrating thoracic injuries. (author)

    Full Text Available Bi Mo,1 Vishnu Garla,2 Lawrence M Wyner1 1Department of Surgery, 2Department of Internal Medicine, Marshall University, Huntington, WV, USA Background: Congenital unilateral absence of the vas deferens occurs in 0.5%–1.0% of males. It has been associated with various genitourinary abnormalities, including renal agenesis. We report a case of congenital unilateral absence of the vas deferens found incidentally during vasectomy in a patient with known unilateral renal agenesis. Case presentation: A 24-year-old male presented to our urology clinic requesting vasectomy. His past history was significant for left renal agenesis. Following successful right vasectomy, several attempts to locate the left vas deferens were unsuccessful. We diagnosed congenital unilateral absence of the vas deferens. Follow-up semen analysis showed azoospermia. Conclusion: As vasectomies are increasingly performed in outpatient settings, it is imperative that physicians be aware of this condition, which can be recognized by a simple physical exam. Recognition could prevent unnecessary surgery and prompt providers to investigate for associated abnormalities. Keywords: vas deferens, embryology, abnormalities, surgery

    Full Text Available Hypodontia is a phenomenon of congenitally missing teeth in human. A thousand and twelve panoramic radiographs of Chinese orthodontic patients were examined for agenesis of permanent teeth including third molars. The patients with missing teeth were divided into four group: the patients with missing less than 4 molars, missing all third molars, hypodontia and oligodontia. The result revealed, 210 patients affected one or more teeth agenesis with a total of 455 teeth missing. The prevalence of tooth agenesis was maxillary third molar 259 (56.9%, mandibular third molar 143 (31.4%, mandibular second premolar 15 (3.3%, mandibular lateral incisors 13 (2.8%, maxillary lateral incisors 8 (1.7%, maxillary second premolars 7 (1.5%, other teeth 10 (2.2% respectively. Of the mesial mandibular first permanent molar, mandibular second premolars were the most frequent missing teeth. Although hypodontia did not represent a public health problem, from orthodontic point of view it might cause esthetic and masticatory function disorders as well as more complex mechanotherapy of a patient.

    Overlap of autoimmune hepatitis and systemic lupus erythematosus (SLE) is a comparatively rare condition. Although both autoimmune hepatitis and SLE can share common autoimmune features such as polyarthralgia, hypergammaglobulinemia and positive ANA, it has been considered as two different entities. We report a case of anti-LKM1 positive autoimmune hepatitis who developed SLE two years later. The presence of interface hepatitis with lymphoplasma cell infiltrates and rosette formation points to the autoimmune hepatitis rather than SLE hepatitis. Autoimmune hepatitis is infrequently accompanied by SLE, therefore, it could be recommended to investigate for SLE in patients with autoimmune hepatitis.

    Back pain is commonly experienced by pregnant women. Evidence suggests that progressive muscle relaxation (PMR) therapy, a complementary therapy widely used by pregnant women, may improve the physical and psychological outcomes of pregnancy. The aim of this study was to investigate the effects of PMR training accompanied by music on perceived pain and quality of life (QOL) in pregnant women with low back pain (LBP). This was a prospective randomized controlled trial. The study was designed to examine the effects of PMR accompanied by music on pregnant women with LBP. In total, 66 pregnant women were assigned randomly to a PMR group or a control group (33 women in each). A personal information form was used as a data collection tool; a visual analog scale was used for measuring pain; and the Short Form-36 was used to evaluate QOL. The control and intervention groups were comparable at baseline. Significant differences were observed between the 2 groups after 4 and 8 weeks of intervention. The intervention group showed significant improvement in all QOL subscales after the intervention. The intervention group, but not the control group, showed significant improvement in perceived pain after the intervention. The intervention group experienced a greater decrease in perceived pain and improved QOL than the control group. Our findings show that PMR accompanied by music may be an effective therapy for improving pain and QOL in pregnant women with LBP. Large randomized studies are recommended to confirm these results. © 2014 by the American College of Nurse‐Midwives.

    Prevalence of dental anomalies in cleft patients is higher than that in general population. The objectives of this study were to assess the prevalence of dental anomalies and their coexistence in French children with cleft and, then, to investigate the relation between the dental anomalies and the cleft type. Seventy-four non-syndromic cleft patients (6-16 years old) from Lille Regional University and Mondor-Chenevier Hospitals (France) were included. Clefts were classified as right/left unilateral cleft lip and palate (UCLP), bilateral cleft lip and palate (BCLP) and cleft palate (CP). Dental anomalies were investigated on panoramic radiographs and categorized as agenesis, supernumerary teeth, incisor rotations, impacted canines and shape anomalies. Prevalence and gender distribution of dental anomalies, mean number of affected teeth per patient, agenesis occurrence and location, and coexistence of dental anomalies were analysed by cleft type. 96.0% of patients presented at least one dental anomaly (agenesis 83.8%, incisor rotations 25.7%, shape anomalies 21.6%, impacted canines 18.9%, supernumerary teeth 8.1%). BCLP patients had a higher number of affected teeth, and left UCLP patients had a higher one compared to right UCLP patients. Distribution of inside (45.3%) and outside (54.7%) cleft region agenesis was similar. Adjacent (31.8%) and not adjacent (33.3%) combined dental anomalies were often encountered. Dental anomalies were localized inside as well as outside cleft region and were often associated with each other. BCLP patients were more affected. Early radiographic evaluation allows a comprehensive diagnosis of inside and outside cleft region anomalies, required for the multidisciplinary dental treatment.

    The aim of this study was to examine the potential relationship between the occurrence of orthodontic root resorption and presence of dental anomalies such as tooth agenesis and pipette-shaped roots. Dental anomalies and root resorption were assessed on dental panoramic tomographs (DPT) of 88 subjects, 27 males and 61 females, mean age 28.4 (SD = 11.3 years), selected from orthodontic patients on the basis of the following exclusion criteria: previous fixed appliance treatment, bad quality of the DPTs and no visibility of the periodontal ligament of every tooth, and younger than 15 years of age at the onset of treatment with fixed edgewise appliance lasting at least 18 months. A pipette-shaped root was identified as defined by a drawing. Tooth agenesis was assessed on DPTs and from subjects' dental history. Root resorption was calculated as the difference between the root length before and after treatment, with and without a correction factor (crown length post-treatment/crown length pre-treatment). If one of the four upper incisors showed root resorption of ≥2.3 mm with both formulas, the patient was scored as having root resorption. Chi-square tests indicated that there was no relationship between orthodontic root resorption and agenesis (P = 0.885) nor between orthodontic root resorption and pipette-shaped roots (P = 0.800). There was no relationship between having one of the anomalies and root resorption either (P = 0.750). In the present study, it was not possible to confirm on DPTs a relationship between orthodontic root resorption and dental anomalies, such as agenesis and pipette-shaped roots.

    2017-12-01

    Senescence is accompanied by loss of reproductive functions. Here, we studied reproductive ageing in Drosophila melanogaster males and asked whether the expected decline in male reproductive success is due to diminished functionality of the male accessory gland (AG). The male AG produces the majority of seminal fluid proteins (SFPs) transferred to the female at mating. SFPs induce female postmating changes and are key to male reproductive success. We measured age-dependent gene expression changes for five representative SFP genes in males from four different age groups ranging from 1 to 6 weeks after eclosion. Simultaneously, we also measured male reproductive success in postmating traits mediated by transfer of these five SFPs. We found a decreased in male SFP gene expression with advancing age and an accompanying decline in male postmating success. Hence, male reproductive senescence is associated with a decline in functionality of the male AG. While overall individual SFP genes decreased in expression, our results point towards the idea that the composition of an ejaculate might change with male age as the rate of change was variable for those five genes. © 2017 John Wiley & Sons Ltd.

    We report a case of huge colon cancer accompanied with severe hypoproteinemia. A7 4-year-old woman was referred to our hospital because of abdominal fullness. Blood examinations revealed anemia(hemoglobin 8.8 g/dL)and sever hypopro- teinemia(total protein 4.5 g/dL, albumin 1.1 g/dL). Computed tomography examination of abdomen revealed ascites and large tumor(12.5×10.5 cm)at the right side colon. By further examinations ascending colon cancer without distant metastasis was diagnosed, then we performed right hemicolectomy and primary intestinal anastomosis by open surgery. Ahuge type 1 tumor(18×12 cm)was observed in the excised specimen, which invaded to terminal ileum directly. The tumor was diagnosed moderately differentiated adenocarcinoma without lymph node metastasis(pT3N0M0, fStage II ). Postoperative course was uneventful and serum protein concentration recovered gradually to normal range. Protein leakage from the tumor cannot be proved by this case, so we can't diagnose as protein-losing enteropathy, but we strongly doubt this etiology from postoperative course in this case.

  7. The notion of Threshold: an investigation into conceptual accompaniment in Aristotle and Hegel

    Directory of Open Access Journals (Sweden)

    Jason Carter

    2010-04-01

    Full Text Available What is unique to the idea of a threshold is that it is a threshold’s proper definition to generate or signal an inevitable accompanying image of a surrounding boundary or a further field of exploration, even though these accompanying terms or images seem like they should be excluded from its definition. Hegel described this phenomenon of the movement from a concept’s definition to its accompanying terms as the determination of a concept through ‘negation’, and viewed such a method as central to philosophical insight. However, what is not usually noted is that Hegel’s notion of negation is both crucially related to Aristotle’s thought on how definitions are formulated, as well as his postulations about opposites and their connection through a third substantial thing. Through a close examination of the problem of Aristotle’s categories, along with Aristotle’s description of the differentiae, movement, and the meaning of the copula, we can demonstrate that Aristotle’s thinking is at core structured by non-binary ‘threshold concepts’ which are essential to his philosophical system. Finally, we will show how Hegel attempted to take these essentially structural threshold concepts in Aristotle and turn their function into a methodology for both thought itself as well as the philosophical determination of the categories of being.Ce qui est particulier à l’idée de seuil c’est que c’est sa propre définition de générer un contour conceptuel qui va vers un autre champ d’exploration, même si ces images de contour semblent devoir être exclues de sa définition. Hegel a décrit ce phénomène du mouvement de la définition d’un concept vers les termes qui l’accompagnent comme la détermination d’un concept à partir de sa « négation » et a considéré cette méthode comme fondamentale à toute approche philosophique. Ce texte explore le fait que la notion hégélienne de la négation remonte aux idées d

    Objective: To explore the diagnostic and therapeutic efficacy of interventional procedure for upper gastrointestinal bleeding in patients of hepatic carcinoma accompanied with hepatic artery-portal vein shunting (HAPVS). Methods: Clinical data of 27 patients of hepatic carcinoma accompanied with HAPVS were retrospectively analyzed. All patients underwent hepatic arterial angiography and transcatheter arterial embolization. Shunts were embolized with coils, Gelfoam particles or PVA particles. Results: Of 27 patients with upper gastrointestinal bleeding, central type HAPVS was seen in 16 and peripheral type HAPVS in 11. Reversed portal venous flow was detected in 20 cases and ascites was found in 23 cases. The abnormal shunts were successfully occluded in all patients and the bleeding ceased within 2 days after embolization. No recurrent bleeding occurred in one month after the treatment. Ascites disappeared in 16 cases and subsided in 7 cases. Conclusion: HAPVS is an important cause for upper gastrointestinal bleeding in patients of hepatic carcinoma, and the arteriovenous fistula can be confirmed with hepatic artery DSA. Embolization of fistulous orifice is the most effective therapy for such patients. (authors)

    Highlights: • HfC naobelts accompanied by HfC nanowires were synthesized by a catalytic CVD method. • HfC nanobelts as a novel structure of HfC ceramic are reported for the first time. • HfC nanobelts have 100–200 μm in lengths and reach up to 10 μm in widths. • The synthesized product is promising field nanoemitters. - Abstract: As a key refractory carbide, hafnium carbide (HfC) is commonly used as structural materials while the field emission (FE) application of HfC in the field of vacuum microelectronics is almost the only one for functional material purposes. Based on its outstanding physical and chemical characteristics, HfC is identified as a potential candidate with satisfactory mechanical properties and long-term and/or high-temperature FE stability for future applications in high-performance field emitters. However, the development of HfC in various FE applications is hindered because it is not facile to fabricate large-scale low-dimensional HfC field nanoemitters. Herein, High-aspect-ratio HfC nanobelts accompanied by HfC nanowires were synthesized on a large scale by a traditional and simple catalytic chemical vapor deposition (CVD) method. Classical vapor–liquid–solid (VLS) theory was employed to explain the growth of the HfC nanowires and nanobelts along axial direction. The thin HfO{sub 2} shell and thin C layer surrounding the nanostructures might give rise to the diameter fluctuation of HfC nanowires and the width increase of HfC nanobelts in lateral direction. Field emission results show that the high-aspect-ratio HfC nanobelts accompanied by the nanowires are promising field nanoemitters, which exhibit excellent field emission properties with a fairly low turn-on field of ∼1.5 V μm{sup −1} and a low current fluctuation less than ∼10%. This suggests that HfC ceramics with high-aspect-ratio nanostructures are ideal cathode material for various field emission applications.

  13. Evidence for coral range expansion accompanied by reduced diversity of Symbiodinium genotypes

    2017-05-15

    Zooxanthellate corals are threatened by climate change but may be able to escape increasing temperatures by colonizing higher latitudes. To determine the effect of host range expansion on symbiont genetic diversity, we examined genetic variation among populations of Symbiodinium psygmophilum associated with Oculina patagonica, a range-expanding coral that acquires its symbionts through horizontal transmission. We optimized five microsatellite primer pairs for S. psygmophilum and tested them on Oculina spp. samples from the western North Atlantic and the Mediterranean. We then used them to compare symbiont genotype diversity between an Iberian core and an expansion front population of O. patagonica. Only one multilocus S. psygmophilum genotype was identified at the expansion front, and it was shared with the core population, which harbored seven multilocus genotypes. This pattern suggests that O. patagonica range expansion is accompanied by reduced symbiont genetic diversity, possibly due to limited dispersal of symbionts or local selection.

    Dynamic computed tomography (CT) scans in 65 hepatocellular carcinomas were analyzed and compared to plain and drip infusion contrast CT scans of those. Scans were obtained before, 10, 30, and 50 seconds after an intravenous bolus injection of 50ml 65% Angiografin. By this method, 49 hepatomas had moderate to marked enhancement at the arterial phase while the enhancement of normal liver parenchyma was only slight at the arterial phase and peaked at the portal phase. Compared to a drip infusion contrast CT, a dynamic CT had advantages to detect an isodense hepatoma in 4 and daughter tumors in 16 both of which were not appreciated by a plain and a drip infusion contrast CT. The tumor extension was also better delineated by a dynamic CT because a part of hepatoma had an isodense area. An arterio-portal shunt was visualized in one. Tumor thrombus in the portal vein was clearly demonstrated in 6 at the portal phase of a dynamic CT. Since a dynamic CT is convenient to perform without any special program or soft wear and gives us very useful information, we believe that it should be routinely employed as a part of a liver CT examination.

    [Purpose] This study evaluated the effective selective activation method of the vastus medialis oblique for knee joint stabilization in patients with patellofemoral pain syndrome. [Subjects and Methods] Fifteen healthy college students (9 males, 6 females); mean age, height, and weight: 22.2 years, 167.8 cm, and 61.4 kg, respectively) participated. The knee angle was held at 60°. Muscle activities were measured once each during an ordinary squat and a squat accompanied by hip joint adduction. The muscle activities of the vastus medialis oblique and vastus lateralis were measured by electromyography for five seconds while maintaining 60° knee flexion. Electromyography signals were obtained at a sampling rate of 1,000 Hz and band pass filtering at 20-50 Hz. The obtained raw root mean square was divided by the maximal voluntary isometric contraction and expressed as a percentage. The selective activity of the vastus medialis oblique was assessed according to the muscle activity ratio of the vastus medialis oblique to the vastus lateralis. [Results] The activity ratio of the vastus medialis oblique was higher during a squat with hip joint adduction than without. [Conclusion] A squat accompanied by hip joint adduction is effective for the selective activation of the vastus medialis oblique.

    A noteworthy metabolic signature accompanying oil body (OB) biogenesis during oilseed development is associated with the modulation of the oil body membranes proteins. Present work focuses on 2-dimensional polyacrylamide gel electrophoresis (2-D PAGE)-based analysis of the temporal changes in the OB membrane proteins analyzed by LC-MS/MS accompanying the onset of desiccation (20–30 d after anthesis; DAA) in the developing seeds of sunflower (Helianthus annuus L.). Protein spots unique to 20–30 DAA stages were picked up from 2-D gels for identification and the identified proteins were categorized into 7 functional classes. These include proteins involved in energy metabolism, reactive oxygen scavenging, proteolysis and protein turnover, signaling, oleosin and oil body biogenesis-associated proteins, desiccation and cytoskeleton. At 30 DAA stage, exclusive expressions of enzymes belonging to energy metabolism, desiccation and cytoskeleton were evident which indicated an increase in the metabolic and enzymatic activity in the cells at this stage of seed development (seed filling). Increased expression of cruciferina-like protein and dehydrin at 30 DAA stage marks the onset of desiccation. The data has been analyzed and discussed to highlight desiccation stage-associated metabolic events during oilseed development. PMID:26786011

    Cases of multiple agenesia present some difficulties in the treatment planing. Three situations may be encountered: limited agenesia, restored by a fixed, bonded or cemented prosthesis, multiple uni- or bimaxillary agenesia without remaining of deciduous teeth, restored by a fixed, bonded or cemented prosthesis or the partial adjacent prosthesis, multiple uni- or bimaxillary agenesia with remaining of deciduous teeth, restored by means of a supra-dental prosthesis. The first two situations have been described in dental literature and are relatively easy to treat. The same is not true for the third situation, where the decision to keep the temporary teeth considerably increases the difficulty of prosthetic restoration. This subject will be illustrated by the presentation of a clinical case of multiple bi-maxillary agenesia. The patient has: on the maxilla: an absence of 9 permanent teeth (18, 15, 14, 12, 22, 23, 24, 25, 28) and the presence of 4 deciduous teeth (62, 63, 64, 65), on the mandible: an absence of all permanent teeth, with the exception of 36 and 46, and the remaining of 4 deciduous teeth (75, 73, 83, 84). The remaining of deciduous teeth and the presence of a very high inter-arch space led to opting for dental coverage so as to keep the deciduous teeth and a proper vertical dimension. The patient wished to solve his "problem" in the maxilla first, and is not wanting to undergo the extraction of his deciduous teeth. The following therapeutic proposal was adapted: On the maxilla, a three-step procedure: first step: building of metal copings on 13, 16 and 26 and metal-ceramic crowns on 11 and 21, second step: building of telescop crowns on 16 and 26 and clasps on 13, 11 and 21, third step: casting of the removable partial denture framework and soldering to the telescop crowns and clasps. On the mandible, a provisional restoration using a supra-dental resin removable partial denture with ceramic occlusal surfaces was adopted. The aesthetic and functional improvement, as well as the comfort provided to the patient due to this kind of mixed prosthesis, appeared to be satisfactory.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

    Infected subdural hematoma(ISH)is a rare disease caused by hematogenous infection of a preexisting subdural hematoma. We report a rare case of ISH accompanied by cerebral infarction. A 76-year-old man who had suffered a closed head injury 3 months before presented fever, headache and left hemiparesis during the medical treatment of acute cholangitis and obstructive jaundice with pancreatic cancer at the department of surgical gastroenterology. At the consultation, computed tomography(CT)scan indicated right chronic subdural hematoma. We performed a burr hole opening surgery on the same day. Abscess and hematoma was aspirated from the subdural space, and methicillin-resistant Staphylococcus aureus(MRSA)was detected in this specimen. Thus the diagnosis of the infected subdural hematoma was confirmed. However, despite the antibiotics therapy, follow-up CT showed a low-density area close to the residual abscess, which suggested cerebral infarction. Cerebral angiography showed a vasospasm at the cortical segment of the right middle cerebral artery near the residual abscess. Eventually we carried out a small craniotomy to evacuate the abscess. Our case showed that prompt surgical treatment is required in case of ISH and the whole hematoma and abscess should be removed as soon as possible with an image diagnosis and an additional surgical operation.

    The method of environment assessment is urgently developed to make various development plans appropriate. It is desirable to grasp synthetically direct and indirect influences to society, since various development activities are deeply related to whole local societies. The Central Research Institute of Electric Power Industry has performed research to develop the method of synthesizing environment assessment, and this is the interim report on the development of the method for forecasting and evaluating the social influence accompanying the location of power stations. As the first approach, the development of the model to forecast the influence of location was started, using the econometric method. In this paper, the works of composing the pilot model, which was made to examine the possibility of model development, are summarized. The fundamental framework of model composition and the theoretical model for each power source and each locality were examined, and the works of making the proving models related to three points based on the theoretical model were carried out. As the result of this work of pilot model composition, the prospect of developing the econometric model for forecasting social environmental influence was obtained, and the works of developing the more versatile master model are advanced at present.

    The inner Bremsstrahlung (I.B.) spectrum accompanying the β-decay of 141 Ce (non-unique first forbidden β-transition) was measured using a single channel scintillation spectrometer. The measured I.B. was analyzed by the variable width peeling-off method. This analyzed and corrected I.B. was compared with those calculated according to the original theories of Knipp and Uhlenbeck as well as of Bloch (KUB), the coulomb corrected theories of Lewis and Ford and of Nilsson, and according to detour-transition calculations of the Ford and Martin theory. Ths shape correction factor suggested by Konopinski and Uhlenbeck on the Fermi β-decay theory was applied to the calculated I.B. based on Nilsson's theory (modified KUB theory). The experimental results are in better agreement with the modified KUB theory than the other theories. (orig.)

    The bilateral vagus nerves (Cranial X) provide both afferent and efferent connections between the viscera and the caudal medulla. The afferent branches increasingly are being recognized as providing significant input to the central nervous system for modulation of complex behaviors. In this paper, we review evidence from our laboratory that increases in vagal afferent activity are involved in perpetuating binge-eating and vomiting in bulimia nervosa. Preliminary findings are also presented which suggest that a subgroup of depressions may have a similar pathophysiology. Two main approaches were used to study the role of vagal afferents. Ondansetron (ONDAN), a 5-HT3 antagonist, was used as a pharmacological tool for inhibiting or reducing vagal afferent neurotransmission. Second, somatic pain detection thresholds were assessed for monitoring a physiological process known to be modulated by vagal afferents, including the gastric branches involved in meal termination and satiety. High levels of vagal activity result in an increase in pain detection thresholds. Depressive symptoms were assessed using the Beck Depression Inventory (BDI). Positron Emission Tomography (PET) was used to identify higher cortical brain areas activated by vagal stimulation produced by proximal gastric distention in normal eating subjects. Double-blind treatment of severe bulimia nervosa subjects with ONDAN resulted in a rapid and significant decrease in binge-eating and vomiting compared to placebo controls. The decrease in abnormal eating episodes was accompanied by a return of normal satiety. Pain detection thresholds measured weekly over the course of the treatment protocol were found to dynamically fluctuate in association with bulimic episodes. Thresholds were the most elevated during periods of short-term abstinence from the behaviors, suggesting that not engaging in a binge/vomit episode is accompanied by an increase in vagal activity. ONDAN also resulted in abolition of the

    Congenital hypothyroidism (CH), as indicated by an elevation of capillary thyroid-stimulating hormone (TSH) at newborn screening, is a preventable cause of mental retardation with varying aetiology; it can be transient or permanent. Radionuclide assessment is currently the gold standard for imaging CH. This study aimed to (i) review the different scintigraphic patterns and correlate them with TSH levels/patient outcomes, (ii) assess the role of sonography in neonates with apparent agenesis as indicated by scintigraphy and (iii) develop a diagnostic investigative algorithm. The technetium thyroid scans of 83 consecutive patients (49 females, average age 32 days) with CH scanned between 2005 and 2009 were retrospectively reviewed. Two nuclear medicine physicians blinded to the clinical details interpreted the scans in consensus. Scintigram appearances were categorised into five groups. Patients scintigraphically diagnosed with thyroid agenesis were evaluated with ultrasound. TSH values and scintigraphic and sonographic findings were correlated with patients' final diagnosis. Based on scintigraphy, 14, 13 and 19 patients out of 83 were assessed as having normal thyroid sites with normal, increased and decreased uptake, respectively. Twenty-two of 83 patients had no uptake, and 15 of 83 patients had ectopic uptake. Higher median TSH levels were seen in no-uptake and ectopic uptake subgroups. Eighteen of 22 patients with no uptake were evaluated with ultrasound. Three of the 18 patients had a normal thyroid gland, and three of 18 patients had a hypoplastic thyroid. Scintigram findings in patients with congenital hypothyroidism fall into five major categories, which have therapeutic implications (lifelong thyroxine in agenesis versus trial of stopping thyroxine in other subgroups). Sonographic demonstration of thyroid tissue in patients scintigraphically diagnosed with thyroid agenesis has major management implications.

    Current knowledge on dental anomalies in patients with incontinentia pigmenti (IP) has been obtained by examining case reports; however, an overall characterization of such alterations remains lacking. The objective of this study was to determine the frequency, type and location of dental alterations in IP using a case series. Fourteen patients (9 children and 5 adults) with a clinical diagnosis of IP who presented dental anomalies were included in this study. All patients were administered a clinical questionnaire, dental examination and radiological investigation. In the present case series, agenesis of primary dentition was present in 60 % of patients and agenesis of permanent tooth was present in 92.8 % of patients. Most cases were missing at least 6 teeth. Second molar agenesis was present in 13 patients (92.8 %). Anomalies in dental crowns occurred in 71.4 % of cases, and the central incisor was most frequently affected. Two adult patients still had primary teeth. Malocclusion was found in 10 patients (71.4 %). High-arched palate was observed in 7 (50 %) patients. Patients with IP present alterations in both primary and permanent dentition. Because the agenesis of permanent teeth is more common, primary teeth are not always replaced. In addition, the durability of primary dentition appears to be greater in IP. This study shows that patients with IP experience significant loss of teeth, especially in permanent dentition, and have an increased risk of high-arched palate compared to the general population. Prophylactic care of primary teeth in IP is relevant for improving functional and aesthetic outcomes until dental prostheses are implanted.

    A comparative study was undertaken to determine the optimum slice thickness and slice gaps that can define the fine contour and continuity of the ossicles and the inner ear. Horizontal tomography was proved to be contributory enough to obtain the whole ossicular chains and the whole labyrinthine capsule. Comparison of 1.5 mm slice thickness / 1.5 mm slice gaps, 1.0 mm slice thickness / 1.0 mm slice gaps and 1.5 mm slice thickness / 1.0 mm slice gaps revealed that the last condition was optimal for demonstrating the ossicular chains, the first for the inner ear. A significant relationship was found between CT findings and surgical findings of ossicular chains in chronic otitis media and cholesteatoma. Radiological classification of the inner ear malformation, which was obtained by this method, were agenesis of the whole labyrinthine capsule, agenesis of the cochlea, slight protrusion of the cochlear growth, poor cochlear turning, agenesis of all the semicircular canals, anterior semicircular canals (s.c.) without posterior and lateral s.c., anterior s.c. without hypoplasia of posterior s.c. and aplasia of lateral s.c., and smallness of the vestibule.

    Combining functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) allows the investigation of spontaneous activities in the human brain. Recently, by using this technique, increases in fMRI signal accompanying transient EEG activities such as sleep spindles and slow waves were reported. Although these fMRI signal increases appear to arise as a result of the neural activities being reflected in the EEG, when the influence of physiological activities upon fMRI signals are taken into consideration, it is highly controversial that fMRI signal increases accompanying transient EEG activities reflect actual neural activities. In the present study, we conducted simultaneous fMRI and polysomnograph recording of 18 normal adults, to study the effect of transient heart rate changes after a K-complex on fMRI signals. Significant fMRI signal increase was observed in the cerebellum, the ventral thalamus, the dorsal part of the brainstem, the periventricular white matter and the ventricle (quadrigeminal cistern). On the other hand, significant fMRI signal decrease was observed only in the right insula. Moreover, intensities of fMRI signal increase that was accompanied by a K-complex correlated positively with the magnitude of heart rate changes after a K-complex. Previous studies have reported that K-complex is closely related with sympathetic nervous activity and that the attributes of perfusion regulation in the brain differ during wakefulness and sleep. By taking these findings into consideration, our present results indicate that a close relationship exists between a K-complex and the changes in cardio- and neurovascular regulations that are mediated by the autonomic nervous system during sleep; further, these results indicate that transient heart rate changes after a K-complex can affect the fMRI signal generated in certain brain regions.

    Full Text Available As part of an ethnographic study, the impact of foreign postings on spouses who accompany military personnel was explored. Individual interviews and focus groups with 34 British military spouses based in one location in southern Europe were conducted. Key findings suggested that reaction to a foreign posting was a reflection of personal attitudes, prior experiences, support, ability to adjust to change and strength of relationship with the serving spouse and community. For many the experience was positive due to the increased opportunity for family time, for others this helped to compensate for the difficulties experienced. Some military spouses experienced significant distress on the posting, particularly if the family was not well-supported. The potential implications of military spouses not adapting to foreign postings have significant implications for healthcare practice. Provision of more appropriate support resources before and during the posting would facilitate the transition for the military spouse and their family.

    Sirenomelia, the Mermaid Syndrome is a rare and lethal congenital anomaly with an incidence of one in 60,000 to 70,000 pregnancies. Sirenomelia is characterized by complete fusion of the lower limbs, commonly associated with renal agenesis, absent external genitalia and other gastrointestinal defects. Another pathognomonic finding is the presence of single umbilical, persistent vitelline artery which is the chief distinguishing anatomic finding from Caudal Regression Syndrome. We report a case of termination of pregnancy done on the basis of ultrasound diagnosis of bilateral renal agenesis with no liquor volume. The foetus was identified to have characteristic features of Sirenomelia at the time of termination.

    To discuss the pathological features of sirenomelia in the light of our 10 cases and review the current theories. We identified 10 patients with sirenomelia from our hospital database. All clinical details and the autopsy features of 10 cases were noted. Of the 10 children with sirenomelia seven had bilateral renal agenesis, three had bladder agenesis and one had a renal hypoplasia. Single umbilical artery was found in 60% of children with sirenomelia. External genitalia was ambiguous in seven of 10 patients. Even though the etiology of caudal regression syndrome (CRS) and sirenomelia remains unknown we tend to believe that sirenomelia and CRS might be different entities.

    The case of 5-month-old female infant with Aicardi's syndrome is presented. The main clinical features were severe developmental retardation and intractable epileptic seizures. Ophthalmoscopic examination revealed pathognomonic choriorethinopathy. Ultrasonic examination of the brain detected agenesis of the corpus callosum, whereas CT showed a coexisting malformation of the brain, i.e. cortical heterotopia of the gray matter. Agenesis of the corpus callosum is an entity well-recognized by sonography. However, ultrasonography is an insufficient modality for the visualization of cortical heterotopia which is common to all cases of Aicardi's syndrome. Therefore, in cases of suspected Aicardi's syndrome CT is recommended, as it enables the diagnosis of cortical heterotopia. (orig.)

    Sequential panoramic radiographs were assessed for mandibular third molar development in 47 long-term survivors of childhood Hodgkin's disease after treatment with 37 Gy mantle field radiation. To make a comparison, panoramic radiographs of 149 healthy, nonirradiated children were reviewed for the presence of mandibular third molars. In children between the ages of 7 and 12 years, bilateral agenesis of mandibular third molars was more frequent in patients who had been treated with mantle radiation than in nonirradiated patients. Unilateral agenesis, crown hypoplasia, and root growth impairment of mandibular third molars were also found. Similar, apparent, radiation-induced developmental anomalies were noted in maxillary third molars of the irradiated patients

    Flexion and extension movements are organized reciprocally, so that extensor motoneurones in the spinal cord are inhibited when flexor muscles are active and vice versa. During and just prior to dorsiflexion of the ankle, soleus motoneurones are thus inhibited as evidenced by a depression......) or soleus muscle of the left ankle. TMS was applied to the hotspot of TA and soleus muscles on separate days. Stimuli were delivered prior to and at the beginning of contraction. Soleus MEPs were significantly facilitated when TMS was applied 50 ms prior to onset of plantar flexion. Surprisingly, soleus...... was increased prior to plantar flexion, but not prior to dorsiflexion. These findings suggest that voluntary contraction at the ankle is accompanied by preceding facilitation of antagonists by a subcortical motor programme. This may help to ensure that the direction of movement may be changed quickly...

  19. The calcineurin inhibitor tacrolimus reduces proteinuria in membranous nephropathy accompanied by a decrease in angiopoietin-like-4.

    Directory of Open Access Journals (Sweden)

    Lei Peng

    Full Text Available Tacrolimus is an anticalcineurinic agent with potent immunosuppressive activity that has recently been shown to have the added benefit of reducing proteinuria in membranous nephropathy (MN patients. However, its potential mechanisms remain unknown. To reveal the mechanism, rat cohorts were administered tacrolimus or vehicle from days 7 to 28 after the induction of passive Heymann nephritis (PHN. PHN induction resulted in heavy proteinuria and increased expression of desmin, a marker of injured podocytes. We also showed that the glomerular expression of angiopoietin-like-4 (Angptl4 was markedly upregulated in PHN rats and human MN followed by an increase in urine Angptl4 excretion. In addition, increased Angptl4 expression may be related to podocyte injury and proteinuria. Furthermore, upregulated Angptl4 expression primarily colocalized with podocytes rather than endothelial or mesangial cells, indicating that podocytes may be the source of Angptl4, which then gradually migrated to the glomerular basement membrane over time. However, tacrolimus treatment markedly reduced glomerular and urinary Angptl4, accompanied by a reduction in the established proteinuria and the promotion of podocyte repair. Additionally, glomerular immune deposits and circulating IgG levels induced by PHN clearly decreased following tacrolimus treatment. In conclusion, this is the first demonstration that the calcineurin inhibitor tacrolimus can reduce Angptl4 in podocytes accompanied by a decrease in established proteinuria and promotion of podocyte repair in MN.

    The present research investigated the resulting contextual fear memory and structural plasticity changes in the dorsal hippocampus (DH) following stress and fear conditioning. This combination enhanced fear retention and increased the number of total and mature dendritic spines in DH. Intra-basolateral amygdala (BLA) infusion of midazolam prior to stress prevented both the enhancement of fear retention and an increase in the density of total and mature dendritic spines in DH. These findings emphasize the role of the stress-induced attenuation of GABAergic neurotransmission in BLA in the promoting influence of stress on fear memory and on synaptic remodeling in DH. In conclusion, the structural remodeling in DH accompanied the facilitated fear memory following a combination of fear conditioning and stressful stimulation.

    Midgut volvulus accompanied by intestinal malrotation is classified as a surgical emergency disease of the newborn, which emerges with the bilious vomiting or melena. This report presents four patients of this disease in our hospital, evaluated by color Doppler ultrasonography before surgical operation. All four patients were presented by bilious vomiting at the onset. By color Doppler ultrasonography method, the whirlpool sign which is the view of intestine and superior mesenteric vein rotated around with the axis of superior mesenteric artery, were shown in all cases. This whirlpool sign led to the diagnosis of midgut volvulus accompanied by intestinal malrotation. Intestinal contrast imaging was tested in three patients for the purpose of confirming the diagnosis. Repair of the volvulus and a ladd operation was performed in all four patients, without the excision of intestine because of no intestinal ischemic change. The clinical courses of four cases were good, and all patients were discharged within 17 days. Early diagnosis and timely surgical operation are essential for decreasing the possibility of occurring intestinal ischemic changes and improving clinical outcome after surgical operation. We propose that color Doppler ultrasonography is the powerful tool for the diagnosis of this disease, especially for the newborn, for whom the available diagnostic tests are limited.

    A crystal has a regular structure, therefore every motion in such a structure seems to be regular. However, it is not actually so and even in perfect crystals the particle motion may be either regular or chaotic. Everything depends on the number of integrals of motion determining a particle trajectory. The character of particle motion in a crystal, i.e. its regularity or chaoticity, affects many physical processes accompanying the particle's motion. In this paper we shall consider the effect of dynamic chaos on the coherent radiation of fast particles in a crystal. We also consider the validity conditions of coherent radiation theory results, the role of the second and higher Born approximations in the radiation theory of fast particles in crystals, the continuous string approximation in this theory, the coherent radiation in the model of random strings, and the multiple scattering effect on the coherent radiation.

    Purpose: A rare but described risk factor for deep venous thrombosis (DVT), predominately in the young, is congenital agenesis or atresia of the inferior vena cava (IVC). The optimal management for DVT in this subset of patients is unknown. We evaluated the efficacy of pharmacomechanical catheter-directed thrombolysis (PCDT) followed by systemic anticoagulation in the treatment of acute lower-extremity DVT in the setting of congenital IVC agenesis or atresia. Materials and Methods: Between November of 2005 and May of 2010, six patients (three women [average age 21 years]) were referred to our department with acute lower-extremity DVT and subsequently found to have IVC agenesis or atresia on magnetic resonance imaging. A standardized technique for PCDT (the Angiojet Rheolytic Thrombectomy System followed by the EKOS Microsonic Accelerated Thrombolysis System) was used for all subjects. Successful thrombolysis was followed by systemic heparinization with transition to Coumadin or low molecular-weight heparin and compression stockings. Subjects were followed-up at 1, 3, and then every 6 months after the procedure with clinical assessment and bilateral lower-extremity venous ultrasound. Results: All PCDT procedures were technically successful. No venous stenting or angioplasty was performed. The average thrombolysis time was 28.6 h (range 12–72). Two patients experienced heparin-induced thrombocytopenia, and one patient developed a self-limited knee hemarthrosis, No patients were lost to follow-up. The average length of follow-up was 25.8 ± 20.2 months (range 3.8–54.8). No incidence of recurrent DVT was identified. There were no manifestations of postthrombotic syndrome. Conclusions: PCDT followed by systemic anticoagulation and the use of compression stockings appears to be safe and effective in relatively long-term follow-up treatment of patients who present with acute DVT and IVC agenesis or atresia.

  6. Neuromodulation of Limb Proprioceptive Afferents Decreases Apnea of Prematurity and Accompanying Intermittent Hypoxia and Bradycardia.

    Directory of Open Access Journals (Sweden)

    Full Text Available Apnea of Prematurity (AOP is common, affecting the majority of infants born at <34 weeks gestational age. Apnea and periodic breathing are accompanied by intermittent hypoxia (IH. Animal and human studies demonstrate that IH exposure contributes to multiple pathologies, including retinopathy of prematurity (ROP, injury to sympathetic ganglia regulating cardiovascular action, impaired pancreatic islet cell and bone development, cerebellar injury, and neurodevelopmental disabilities. Current standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and methylxanthine therapy; these interventions are inadequate, and not optimal for early development.The objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements trigger reflexive facilitation of breathing.Premature infants (23-34 wks gestational age, with clinical evidence of AOP/IH episodes were enrolled 1 week after birth. Caffeine treatment was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in 6 hour ON/OFF sequences for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2, and breathing pauses were continuously collected.Fewer respiratory pauses occurred during vibration periods, relative to baseline (p<0.005. Significantly fewer SpO2 declines occurred with vibration (p<0.05, relative to control periods. Significantly fewer bradycardic events occurred during vibration periods, relative to no vibration periods (p<0.05.In premature neonates, limb proprioceptive stimulation, simulating limb movement, reduces breathing pauses and IH episodes, and lowers the number of bradycardic events that accompany aberrant breathing episodes. This low-cost neuromodulatory procedure has the potential to provide a non-invasive intervention to reduce apnea, bradycardia and

    Callosal dysgenesis is a malformation of the corpus callosum with origins in the embryogenesis of the telencephalon. We reviewed the computed tomography and magnetic resonance imaging findings of 11 patients with callosal dysgenesis and one patient with normal corpus callosum associated with a lipoma. The patients were divided into three distinct groups: total agenesis (three patients), partial agenesis (six patients) and hypoplasia (two patients). Associated abnormalities were observed in nine patients, including Chiari II malformation (one patient), schizencephaly (one patient), interhemispheric cyst (two patients), Dandy-Walker cyst (one patient), nodular heterotopy (one patient) and lipoma of the corpus callosum (four patients). This paper presents a review that may contribute to the diagnosis of these disorders. (author)

    Five cases of sirenomelia presented with rare manifestations are discussed. Three neonates were born alive and died within 2 to 12 hours after birth. One case was the offspring of a triple in vitro fertilization pregnancy with history of early intrauterine death of one of the triplets. The main features included fusion of lower extremities (five of five), renal agenesis (three of five), polycystic renal dysplasia (two of five), anal atresia with large bowel hypoplasia (three of five), pulmonary hypoplasia (four of five), and single umbilical artery (five of five). Other features that have only rarely been associated with sirenomelia included concurrence of congenital heart disease and neuroblastoma, gallbladder agenesis, and upper extremity defects.

    The case of 5-month-old female infant with Aicardi's syndrome is presented. The main clinical features were severe developmental retardation and intractable epileptic seizures. Ophthalmoscopic examination revealed pathognomonic choriorethinopathy. Ultrasonic examination of the brain detected agenesis of the corpus callosum, whereas CT showed a coexisting malformation of the brain, i.e. cortical heterotopia of the gray matter. Agenesis of the corpus callosum is an entity well-recognized by sonography. However, ultrasonography is an insufficient modality for the visualization of cortical heterotopia which is common to all cases of Aicardi's syndrome. Therefore, in cases of suspected Aicardi's syndrome CT is recommended, as it enables the diagnosis of cortical heterotopia.

  13. Accompanying role of hepato-biliary-pancreas surgeon in urological surgery

    Directory of Open Access Journals (Sweden)

    Atsushi Nanashima

    Full Text Available Introduction: The present case reports demonstrated the accompanying surgical support from hepato-biliary-pancreas (HBP surgeons for urological surgery to secure operative safety because HBP surgeons are well experienced in dissecting techniques for mobilization of the liver or pancreas. We experienced 9 consecutive patients who underwent nephrectomy, adrenectomy or resection of retroperitoneal tumors by urological surgeons. Cardiovascular intervention was also required in cases of long tumor thrombus into the vena cava. Cases: All patients had no severe co-existing diseases except the main tumor. Reverse T-shape incision was performed in 7 cases and thoracolaparotomy in two. Dissection and mobilization at the site of severe compression by the urinary tumors were performed in three cases. Partial liver resection was performed for testicular liver metastases in two, and right hepatectomy for right renal cancer was performed in one. Encircling the vena cava and preparation of transection for tumor thrombi were performed in three, and among these, cardiovascular intervention was necessary in two because of extension into the right atrium. During admission, all patient outcomes were uneventful without severe complications. We herein showed the representative two cases of combined surgery. Discussion: and conclusion The point of this case report is the coordination between each surgeon and anesthesiologist under precise perioperative planning or management. The role of HBP surgeons is to provide information as a specialist on the operative field for urological or cardiovascular surgery to achieve operative safety.

    Cysticercosis is a parasitic disease in which man serves as the intermediate host of Taenia Solium, the pork tapeworm. The computed tomographic findings of 25 cases of intracerebral cysticercosis proven by pathologic and/or clinical findings during past 2 years were analysed. The results were as follows; 1. The sex was 19 males and 6 females, and 56 percent of the patients were seen in fourth and fifth decades. The most common symptom was epilepsy (72%). 2. The C. T. findings in precontrast study were varied; such as ill defined low density (48%), cystic low density (20%), dilated ventricles (20%), ill defined low density with isodense nodule (18%), cystic low density with isodense mural nodule (12%) and calcification (8%). 3. The areas of involvement were 20 cases (80%) of parenchymal form, 3 cases (12%) of ventricular form and 2 cases (8%) of mixed form. 4. The contrast-enhanced 13 cases were 5 nodular, 5 ring or rim-like and 3 mixed type enhancements, while 12 cases were not enhanced. 5. C.T. scan demonstrated more precise location and extents of cerebral cysticercosis, especially in parenchymal form. It was considered to be important in determination of surgical feasibility and its approach.

  15. Dynamic computed tomography for the diagnosis of pituitary microadenoma, 2

    1992-01-01

    The purpose of this paper is to establish the diagnostic criteria on microadenoma by dynamic CT. Dynamic CT was studied in 19 patients with hormone-secreting microadenomas. There were 10 prolactin-secreting, 5 growth-hormone-secreting, and 4 adrenocorticotropic-hormone-secreting adenomas. The following diagnostic criteria on microadenomas were concluded by analyzing dynamic CT on 19 microadenomas, in which histology, location and extension of the tumor were verified by surgery and postoperative CT. The tuft distorted and displaced indicates a mass effect mainly in the opposite side. The mid-situated tuft with a disproportionately small size compared with a size of the anterior lobe indicates a mass effect mainly in the midportion. The area, into which a high density at the tuft definitely spreads, presents the normal anterior lobe. The area, in which less increase in density than the former area is observed, indicates an abnormal mass. In the time-density curve, the former area represents the vascular pattern or the hypervascular extravasation pattern, while the latter area represents extravasation of contrast material in a hypovascular tissue. Only eight microadenomas were presented as a less enhanced mass. The rest of the cases exhibited adenomas isodense to the normal pituitary gland. Dynamic CT was useful particularly in the diagnosis of isodense adenomas. (author)

    1997-01-01

    During phase III of the HDR Safety Programme (HDR: decommissioned overheated steam reactor in Karlstein, Germany), experiments were performed in test group E22 on small-bore austenitic straight piping and on pipe elbows and branches containing through-wall cracks. The main aim was the determination of crack opening and leak rate behaviour for the cracked components under almost operational pressure and temperature loading conditions, especially including transient bending moments. In addition to machined slits, naturally grown fatigue cracks were also considered to cover the leakage behaviour. The experiments were accompanied by calculations, mainly performed by GRS. The paper describes the most important aspects and the essential results of the calculations and analysis. The main outcome was that the crack opening and initiation of crack growth can be described with the finite element techniques applied with sufficient accuracy. However, the qualification of the leak rate models could not be completed successfully, and therefore more sophisticated experiments of this kind are needed. (orig.)

    A rare case of the insulin autoimmune syndrome (IAS) accompanied by insulin receptor anomaly is reported. Antibodies to insulin and insulin receptor were determined in the patient with severe hypoglycaemia before and after the treatment with prednisolone. Titers of antibody to insulin and insulin receptors were 73.0% and 41.5%, respectively. Drug-induced lymphocyte stimulation tests were all negative for the suspicious drugs. Her HLA-DR was DRB1*0403/04051. Following steroid therapy, the formation of antibodies was suppressed and alleviated her symptoms. Scatchard analysis yielded findings specific to polyclonal antibodies. The changes in autoantibodies resulted in alleviation of the hypoglycemic symptoms as a result of steroid therapy.

    We investigate the transient electronic structure of BaFe2As2 , a parent compound of iron-based superconductors, by time- and angle-resolved photoemission spectroscopy. In order to probe the entire Brillouin zone, we utilize extreme ultraviolet photons and observe photoemission intensity oscillation with the frequency of the A1 g phonon which is antiphase between the zone-centered hole Fermi surfaces (FSs) and zone-cornered electron FSs. We attribute the antiphase behavior to the warping in one of the zone-centered hole FSs accompanying the displacement of the pnictogen height and find that this displacement is the same direction as that induced by substitution of P for As, where superconductivity is induced by a structural modification without carrier doping in this system.

    We present four cases of primary cerebral lymphoma in non-immunodepressed adult patients. All cases were dsemonstrated with pathological study. CAT study showed solitary or multiple isodense lesions, which incorporated avidly and homoneneously the contrast. Arteriography performed in three patients and magnetic resonance, performed in one did not help for diagnosis. We also review the radiological findings obtained with different imaging methods, and suggest the criteria which could be useful for early diagnosis (Author)

    Torsion of uterine adnexa is an important cause of acute abdominal pain in females. The main organ which can cause torsion is the ovaries, but torsions of the fallopian tube, subserosal myoma, paratubal cyst, and even the uterine body have been reported. The incidence of isolated fallopian tubal torsion is very rare. Even more rarely, it can coil around nearby organs such as the utero-ovarian ligament, showing similar clinical manifestations with those of adnexal torsion. We experienced an extremely rare case of acute abdomen induced by ovarian congestion triggered by the fallopian tube accompanying a paratubal cyst coiling around the utero-ovarian ligament. The right paratubal cyst was misinterpreted as being part of a cystic component of the left ovary on preoperative sonographic examination, and the coiling of the right fallopian tube accompanying the paratubal cyst was misdiagnosed as torsion of the right ovary. We report this rare case with a brief literature review.

    In nuclear medicine, radioisotopes are bound to various pharmaceuticals for use in diagnostic and therapeutic applications. These unsealed sources are administered in various forms to patients, who remain radioactive for hours or days, and represent a source of potential radiation exposure for others. Thus, in nuclear medicine departments, radiation protection of workers and members of the public (especially persons accompanying patients) must consider this exposure. In this study, thermoluminescent dosimeters were given to various persons who were accompanying patients in two nuclear medicine departments in Recife, Pernambuco State, Brazil. Exposure results are given, and issues regarding exposure conditions and times for members of the public in these departments are discussed. (author)

    Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to deficiency of sex steroid hormone. Graves' disease is also an important cause of secondary osteoporosis. However, IHH does not preclude the development of primary hyperthyroidism caused by Graves' disease, leading to more severe osteoporosis rapidly. Here, we describe the first case of 35-year-old Asian female patient with IHH accompanied by Graves' disease and osteoporosis-induced multiple fractures. Endocrine laboratory findings revealed preserved anterior pituitary functions except for secretion of gonadotropins and showed primary hyperthyroidism with positive autoantibodies. Sella magnetic resonance imaging showed slightly small sized pituitary gland without mass lesion. Dual energy X-ray absorptiometry revealed severe osteoporosis in lumbar spine and femur neck of the patient. Plain film radiography of the pelvis and shoulder revealed a displaced and nondisplaced fracture, respectively. After surgical fixation with screws for the femoral fracture, the patient was treated with antithyroid medication, calcium, and vitamin D until now and has been recovering fairly well. We report a patient of IHH with Graves' disease and multiple fractures that is a first case in Korea.

    Full Text Available Objective: Analise feelings of women accompanying children in a paediatric intensive care unit Materials and Methods: Data were collected from August to October 2015 by the authors from individual interviews recorded with 15 women. The instrument was structured with the identification of qualitative variables, described in absolute and relative frequencies, and a guiding question. The "corpus" of each interview was electronically transcribed, floating readings were held and statements were categorized and analysed according Analise Content.  Results: 14 (93% are biological mothers; average age 30 years; 11 (73% have completed primary education; six (46% have an occupation or a profession. The four themes were inferred: ambivalence of feelings and coping were related to how individuals express and deal with the hospitalized patient’s situation; empathy with the health team and the structural condition of the critical environment can also generate feelings. Nursing diagnoses were formulated from the reported feelings. Conclusion: It was observed that the feelings identified could be originated by the health-illness hospitalization process as well as the structural components of the critical environment.

    Primordial dwarfism is a state of extreme prenatal and postnatal growth deficiency, and is characterized by marked clinical and genetic heterogeneity. Two presumably unrelated consanguineous families presented with an apparently novel form of primordial dwarfism in which severe growth deficiency is accompanied by distinct facial dysmorphism, brain malformation (microcephaly, agenesis of corpus callosum, and simplified gyration), and severe encephalopathy with seizures. Combined autozygome/exome analysis revealed a novel missense mutation in WDR4 as the likely causal variant. WDR4 is the human ortholog of the yeast Trm82, an essential component of the Trm8/Trm82 holoenzyme that effects a highly conserved and specific (m(7)G46) methylation of tRNA. The human mutation and the corresponding yeast mutation result in a significant reduction of m(7)G46 methylation of specific tRNA species, which provides a potential mechanism for primordial dwarfism associated with this lesion, since reduced m(7)G46 modification causes a growth deficiency phenotype in yeast. Our study expands the number of biological pathways underlying primordial dwarfism and adds to a growing list of human diseases linked to abnormal tRNA modification.

    To evaluate types of gray matter heterotopias, associated brain anomalies, and its correlation with the patterns of seizure. We evaluated retrospectively 19 patients (male:female=10:9, mean age 21 years) with gray matter heterotopias on brain MRI. Using 1.0T superconducting MR unit, spin echo T1-, proton -density and T2-weighted images in axial, coronal and sagittal planes were obtained. Types of gray matter heterotopias were single subependymal in four patients, multiple subependymal in one, focal subcortical in eight, diffuse subcortical in two, mixed multiple subependymal and focal subcortical in four. Associated anomalies were seen in 11 patients: other neuronal migration anomalies in eight patients, corpus callosum agenesis in two, and combined holoprosencephaly and Dandy-Walker malformation in one. Fifteen patients had seizure. The patterns of seizure were not correlated with the types of heterotopias. In addition to subependymal, focal subcortical, and diffuse subcortical types, gray matter heterotopias included mixed variant of multiple subependymal and subcortical type. Schizencephaly was the most common form of accompanying anomalies, and patterns of seizure were not correlated with types of gray matter heterotopias, even though main clinical manifestation was seizure

    Full Text Available Diastemas are spaces or gaps between two or more consecutive teeth. They can occur anywhere in the upper or lower dental arches. Diastemas can occur in mixed dentition and closes spontaneously when the canines erupt, but in certain circumstances, diastema will persist until period of permanent teeth. This etiologic factor has to identify because it will influenc effectivenees of closing the multiple diastemas. The multiple diastemas that happened at the anterior upper and lower which caused by deficient tooth structure and missing of some teeth (agenesis, accompanied of central diastema which influenced by anterior labialis frenulum, should treated comprehensively.

The purpose of this study was to investigate the cytokine profiles in tears associated with the secondary conjunctival response (SCR) types. In 47 AC patients developing 16 immediate (SICR; p tears. The SCRs were associated with significant concentration changes of particular cytokines in tears (p tears during the phosphate-buffered saline controls or negative SCRs. Different cytokine profiles in the tears accompanying the immediate, late and delayed types of SCR, induced by nasal allergy, would indicate involvement of different hypersensitivity mechanisms in the particular SCR types. The low cytokine concentrations in tears recorded during the SCRs may suggest their origin from the nasal mucosa. These results emphasize the diagnostic value of NPTs with allergens combined with monitoring of various ocular features in patients suffering from the secondary form of AC. These results may also have an impact on the therapeutical approach to this clinical entity.

    A possibility of using clay waste rocks (shales) from coal mines in the removal of heavy metals from industrial wastewaters is considered in this paper. Raw and calcined (600 °C) shales accompanying the coal beds in two Polish coal mines were examined with respect to their adsorptive capabilities for Pb, Ni and Cu ions. The mineralogical composition of the shales was determined and the TG/DTG analysis was carried out. The granulometric compositions of raw and calcined shales were compared. Tests of adsorption for various Pb(II), Ni(II) and Cu(II) concentrations were conducted and the pH before and after adsorption was analyzed. The results indicate that the shales from both coal mines differ in adsorptive capabilities for particular metal ions. The calcination improved the adsorptive capabilities for lead, but worsened them for nickel. The examined shales have good adsorptive capabilities, and could be used as inexpensive adsorbents of heavy metal ions, especially in the regions where resources of shale are easy accessible in the form of spoil tips.

    Full Text Available    Diaphragmatic hernia arises from pleuro-peritoneal membranes inability to close pericardioperitoneal membranes. Diaphragmatic defect may be located in esophageal hiatus (hiatal hernia, nearby the hiatus (paraesophageal, retrosternal (Morgagni or posterolateral (Bochdalek. Congenital diaphragmatic hernias (CDH diagnosed after neonatal period are defined as late presenting CDH. This group of patients consist 5-31% of CDHs and lead to diagnostic difficulties. A case of adult type Bochdalek hernia who was admitted to our clinic with respiratory problems and recognized late with the absence of left diaphragm was discussed in the light of clinical and surgical methods.

    Nonradioactive xenon was used for enhancement in computed tomography in a series of 18 patients requiring general anesthesia. The method and results are described. The properties of xenon are radically different from those of intravenous iodides, and the enhancement patterns demonstrate different aspects of both normal and abnormal tissues. In our limited experience, it has been of value in those isodense and low attenuation lesions that have not enhanced after intravenous Conray. (orig.) 891 MG/orig. 892 MB [de
