    Congenital central hypoventilation syndrome is a rare syndrome present from birth, and is defined as the failure of automatic control of breathing. All patients with congenital central hypoventilation syndrome require life-long ventilatory support during sleep, although approximately a third of patients require ventilatory support 24 h per day. Diaphragm pacers offer a modality of ventilatory support that affords congenital central hypoventilation syndrome patients with maximal mobility for full-time ventilatory patients, and they may allow for a more normal lifestyle in the appropriate patient. They may permit tracheostomy decannulation in those requiring only support during sleep. Diaphragm pacing entails surgical placement of an electrode onto the phrenic nerve, connected to a subcutaneous receiver. There is an external battery-operated transmitter and antenna placed on the skin over the receiver. The transmitter emits energy, similar to radio transmission, which is converted into an electrical current by the receiver. This stimulates the phrenic nerve resulting in a diaphragmatic contraction. Settings on the transmitter include respiratory rate and electrical voltage, and are adjusted to give enough tidal volume to allow for adequate oxygenation and ventilation. Therefore, diaphragm pacing is an attractive alternative mode of mechanically assisted ventilation for many patients with congenital central hypoventilation syndrome.

Affected patients have absent or negligible ventilatory sensitivity to hypercapnia and hypoxemia, and they do not exhibit signs of respiratory distress when challenged with hypercarbia or hypoxia. The diagnosis of CCHS must be confirmed with PHOX2B gene mutation. Generally, the PHOX2B mutation genotype can aid in anticipating the severity of the phenotype. They require ventilatory support for life. Home assisted ventilation options include positive pressure ventilation via tracheostomy, noninvasive positive pressure ventilation, and diaphragm pacing via phrenic nerve stimulation, but each strategy has its associated limitations and challenges. Since all the clinical manifestations of CCHS may not manifest at birth, periodic monitoring and early intervention are necessary to prevent complications and improve outcome. Life-threatening arrhythmias can manifest at different ages and a normal cardiac monitoring study does not exclude future occurrences leading to the dilemma of timing and frequency of cardiac rhythm monitoring and treatment. Given the rare incidence of CCHS, most health care professionals are not experienced with managing CCHS patients, particularly those with diaphragm pacers. With early diagnosis and advances in home mechanical ventilation and monitoring strategies, many CCHS children are surviving into adulthood presenting new challenges in their care.

    Full Text Available Children with congenital central hypoventilation syndrome (CCHS, a genetic disorder characterized by diminished drive to breathe during sleep and impaired CO(2 sensitivity, show brain structural and functional changes on magnetic resonance imaging (MRI scans, with impaired responses in specific hippocampal regions, suggesting localized injury.We assessed total volume and regional variation in hippocampal surface morphology to identify areas affected in the syndrome. We studied 18 CCHS (mean age+/-std: 15.1+/-2.2 years; 8 female and 32 healthy control (age 15.2+/-2.4 years; 14 female children, and traced hippocampi on 1 mm(3 resolution T1-weighted scans, collected with a 3.0 Tesla MRI scanner. Regional hippocampal volume variations, adjusted for cranial volume, were compared between groups based on t-tests of surface distances to the structure midline, with correction for multiple comparisons. Significant tissue losses emerged in CCHS patients on the left side, with a trend for loss on the right; however, most areas affected on the left also showed equivalent right-sided volume reductions. Reduced regional volumes appeared in the left rostral hippocampus, bilateral areas in mid and mid-to-caudal regions, and a dorsal-caudal region, adjacent to the fimbria.The volume losses may result from hypoxic exposure following hypoventilation during sleep-disordered breathing, or from developmental or vascular consequences of genetic mutations in the syndrome. The sites of change overlap regions of abnormal functional responses to respiratory and autonomic challenges. Affected hippocampal areas have roles associated with memory, mood, and indirectly, autonomic regulation; impairments in these behavioral and physiological functions appear in CCHS.

    @@ Congenital central hypoventilation syndrome(CCHS, OMIM #209880) is a rare autosomal dominant disorder of the autonomic nervous system(ANS) characterized by an abnormal autonomic ventilatory response to progressive hypercarbia and sustained hypoxemia. Patients typically present in the newborn period with hypoventilation or apnea asleep, awake, or both, without any associated cardiac, pulmonary, neuromuscular or brainstem lesions. Rarely, some patients may present at a later age and are diagnosed to have late onset central hypoventilation syndrome (LOCHS).1 Other features of ANS dysfunction such as feeding difficulty due to oesophageal dysmotility, severe constipation in the absence of Hirschsprung disease, poor regulation of basal body temperature, episodes of profuse sweating, pupillary and ocular abnormalities,decreased beat-to-beat variability of heart rate,attenuated response of heart rate to exercise,abnormal fluctuation of blood pressure, decreased perception to pain, and decreased perception to anxiety may be variably present but not essential for diagnosis.

    Central alveolar hypoventilation syndrome (CAH), or Ondine's curse, is a very rare disease characterized by dysfunction of respiratory center in the brain stem. Here, we report a case of CAH associated with cerebral infarction. A 59-year-old man developed right facial sensory deficit at age 56. Then, the facial sensory deficit spread to the left side and dysarthria and dysphagia also developed. Since age 58, he often developed respiratory failure and consciousness disturbance. Arterial blood gas analysis revealed alveolar hypoventilation and respiratory acidosis. Disorders of peripheral organs such as lung, airway, thorax and neuromuscular diseases were ruled out. Brain MRI showed cerebral infarction in the brain stem. We diagnosed him as CAH associated with brain stem infarction.

    Abstract Objective: To report the case of a newborn with recurrent episodes of apnea, diagnosed with Congenital Central hypoventilation syndrome (CCHS) associated with Hirschsprung's disease (HD), configuring Haddad syndrome. Case description: Third child born at full-term to a non-consanguineous couple through normal delivery without complications, with appropriate weight and length for gestational age. Soon after birth he started to show bradypnea, bradycardia and cyanosis, being submitted to tracheal intubation and started empiric antibiotic therapy for suspected early neonatal sepsis. During hospitalization in the NICU, he showed difficulty to undergo extubation due to episodes of desaturation during sleep and wakefulness. He had recurrent episodes of hypoglycemia, hyperglycemia, metabolic acidosis, abdominal distension, leukocytosis, increase in C-reactive protein levels, with negative blood cultures and suspected inborn error of metabolism. At 2 months of age he was diagnosed with long-segment Hirschsprung's disease and was submitted to segment resection and colostomy through Hartmann's procedure. A genetic research was performed by polymerase chain reaction for CCHS screening, which showed the mutated allele of PHOX2B gene, confirming the diagnosis. Comments: This is a rare genetic, autosomal dominant disease, caused by mutation in PHOX2B gene, located in chromosome band 4p12, which results in autonomic nervous system dysfunction. CCHS can also occur with Hirschsprung's disease and tumors derived from the neural crest. There is a correlation between phenotype and genotype, as well as high intrafamilial phenotypic variability. In the neonatal period it can simulate cases of sepsis and inborn errors of metabolism. PMID:26838603

  8. Impaired Neural Structure and Function Contributing to Autonomic Symptoms in Congenital Central Hypoventilation Syndrome

    Full Text Available Congenital central hypoventilation syndrome (CCHS patients show major autonomic alterations in addition to their better-known breathing deficiencies. The processes underlying CCHS, mutations in the PHOX2B gene, target autonomic neuronal development, with frame shift extent contributing to symptom severity. Many autonomic characteristics, such as impaired pupillary constriction and poor temperature regulation, reflect parasympathetic alterations, and can include disturbed alimentary processes, with malabsorption and intestinal motility dyscontrol. The sympathetic nervous system changes can exert life-threatening outcomes, with dysregulation of sympathetic outflow leading to high blood pressure, time-altered and dampened heart rate and breathing responses to challenges, cardiac arrhythmia, profuse sweating, and poor fluid regulation. The central mechanisms contributing to failed autonomic processes are readily apparent from structural and functional magnetic resonance imaging studies, which reveal substantial cortical thinning, tissue injury, and disrupted functional responses in hypothalamic, hippocampal, posterior thalamic, and basal ganglia sites and their descending projections, as well as insular, cingulate, and medial frontal cortices, which influence subcortical autonomic structures. Midbrain structures are also compromised, including the raphe system and its projections to cerebellar and medullary sites, the locus coeruleus, and medullary reflex integrating sites, including the dorsal and ventrolateral medullary nuclei. The damage to rostral autonomic sites overlaps metabolic, affective and cognitive regulatory regions, leading to hormonal disruption, anxiety, depression, behavioral control, and sudden death concerns. The injuries suggest that interventions for mitigating hypoxic exposure and nutrient loss may provide cellular protection, in the same fashion as interventions in other conditions with similar malabsorption, fluid turnover

  9. The cerebral cost of breathing: an FMRI case-study in congenital central hypoventilation syndrome.

    Directory of Open Access Journals (Sweden)

    Mike Sharman

    Full Text Available Certain motor activities--like walking or breathing--present the interesting property of proceeding either automatically or under voluntary control. In the case of breathing, brainstem structures located in the medulla are in charge of the automatic mode, whereas cortico-subcortical brain networks--including various frontal lobe areas--subtend the voluntary mode. We speculated that the involvement of cortical activity during voluntary breathing could impact both on the "resting state" pattern of cortical-subcortical connectivity, and on the recruitment of executive functions mediated by the frontal lobe. In order to test this prediction we explored a patient suffering from central congenital hypoventilation syndrome (CCHS, a very rare developmental condition secondary to brainstem dysfunction. Typically, CCHS patients demonstrate efficient cortically-controlled breathing while awake, but require mechanically-assisted ventilation during sleep to overcome the inability of brainstem structures to mediate automatic breathing. We used simultaneous EEG-fMRI recordings to compare patterns of brain activity between these two types of ventilation during wakefulness. As compared with spontaneous breathing (SB, mechanical ventilation (MV restored the default mode network (DMN associated with self-consciousness, mind-wandering, creativity and introspection in healthy subjects. SB on the other hand resulted in a specific increase of functional connectivity between brainstem and frontal lobe. Behaviorally, the patient was more efficient in cognitive tasks requiring executive control during MV than during SB, in agreement with her subjective reports in everyday life. Taken together our results provide insight into the cognitive and neural costs of spontaneous breathing in one CCHS patient, and suggest that MV during waking periods may free up frontal lobe resources, and make them available for cognitive recruitment. More generally, this study reveals how the

    5 cases with obesity-hypoventilaion syndrome were reported. The clinical manifestations were obesity, palpitation, dyspnea, lethargy, cyanosis, distention of cervical vein, edema, enlargement of liver and hypertension. All of them were initially diagnosed as chronic bronchitis or heart diseases. Pulmonary function test showed restrictive ventilative defect and hypercapnia with hypoxemia. Mouth oclusion pressure at 0.1 second was higher than the normal value. The response to CO2 was decreased. Hypertrophy of right heart was shown in ECG and X-ray film improvement in symptoms and blood gases analyses were found to be associated with body weight decrease in a follow up period of one year.

    Neuroblastoma in patients with congenital central hypoventilation syndrome (CCHS) as part of a neurocristopathy syndrome is a rare finding and has only been associated with paired-like homeobox 2b (PHOX2B) non-polyalanine-repeat-expansion mutations. To the best of our knowledge, we report the first case of a child with CCHS and Hirschsprung disease who had a PHOX2B polyalanine-repeat-expansion mutation (PARM) (genotype 20/33) and developed high-risk neuroblastoma. We further describe his treatment including chemotherapy and therapeutic I(131) -metaiodobenzylguanidine. This case highlights the need to consider neuroblastoma in patients with CCHS and the longest PHOX2B PARMs and to individualize treatment based on co-morbidities.

    We report a case of a 53-year-old man presenting with depressed alertness and severe excessive sleepiness in the setting of neurosarcoidosis. Neuroimaging demonstrated hypothalamic destruction due to sarcoidosis with a CSF hypocretin level of 0 pg/mL. The patient also experienced respiratory depression that presumably resulted from hypocretin-mediated hypothalamic dysfunction as a result of extensive diencephalic injury. This is a novel case, demonstrating both hypocretin deficiency syndrome, as well as respiratory dysfunction from destruction of hypocretin neurons and extensive destruction of key diencephalic structures secondary to the underlying neurosarcoidosis.

    Background: As obesity increases, the frequency of obstructive sleep apnea and obesity hypoventilation syndrome increases also. However, obesity hypoventilation syndrome frequency is not known, as capnography and arterial blood gas analysis are not routinely performed in sleep laboratories. Aims: To investigate the frequency and predictors of obesity hypoventilation syndrome in obese subjects. Study Design: Retrospective clinical study. Methods: Obese subjects who had arterial blood gas analysis admitted to the sleep laboratory and polysomnography were retrospectively analyzed. Subjects with restrictive (except obesity) and obstructive pulmonary pathologies were excluded. Demographics, Epworth-Sleepiness-Scale scores, polysomnographic data, arterial blood gas analysis, and spirometric measurements were recorded. Results: Of the 419 subjects, 45.1% had obesity hypoventilation syndrome. Apnea hypopnea index (p<0.001), oxygen desaturation index (p<0.001) and sleep time with SpO2<90% (p<0.001) were statistically higher in subjects with obesity hypoventilation syndrome compared to subjects with eucapnic obstructive sleep apnea. The nocturnal mean SpO2 (p<0.001) and lowest SpO2 (p<0.001) were also statistically lower in subjects with obesity hypoventilation syndrome. Logistic regression analysis showed that the lowest SpO2, oxygen desaturation index, apnea hypopnea index and sleep time with SpO2 <90% were related factors for obesity hypoventilation syndrome. Conclusion: Obesity hypoventilation syndrome should be considered when oxygen desaturation index, apnea hypopnea index and sleep time with SpO2 <90% are high. PMID:28251022

    Central hypoventilation is usually caused by ischaemic or neoplastic lesions of the medulla and upper cervical spinal cord. An autoimmune disorder is not usually considered in the differential diagnosis of this syndrome. We retrospectively identified 14 patients from our database of 202 patients with Hu antibodies who presented with brainstem symptoms. Three were admitted to hospital because of central hypoventilation. All underwent intubation and mechanical ventilation. They could breathe properly while they were awake but suffered deep apnoeas during sleep. Two died, but one is still alive requiring ventilatory assistance during sleep. Autopsy was performed in one of the patients which showed severe inflammatory infiltrates and neuronal loss in the medulla. All patients had normal brain imaging studies and the cause of central hypoventilation was an unsolved problem until Hu antibodies were determined.

    Fetuses as early as 15 weeks' gestation exhibit rhythmical respiratory movements shown by real-time ultrasonography. The nucleus/tractus solitarius is the principal brainstem respiratory center; other medullary nuclei also participate. The purpose was to determine temporal maturation of synaptogenesis. Delayed synaptic maturation may explain neurogenic apnea or hypoventilation of prematurity and some cases of sudden infant death syndrome. Sections of medulla oblongata were studied from 30 human fetal and neonatal brains 9 to 41 weeks' gestation. Synaptophysin demonstrated the immunocytochemical sequence of synaptogenesis. Other neuronal markers and myelin stain also were applied. The nucleus/tractus solitarius was similarly studied in fetuses with chromosomopathies, metabolic encephalopathies, and brain malformations. Synapse formation in the nucleus solitarius begins at about 12 weeks' gestation and matures by 15 weeks; myelination initiated at 33 weeks. Synaptogenesis was delayed in 3 fetuses with different conditions, but was not specific for only nucleus solitarius. Delayed synaptogenesis or myelination in the nucleus solitarius may play a role in neonatal hypoventilation, especially in preterm infants and in some sudden infant death syndrome cases.

    Full Text Available The concept of central sleep apnoea or hypoventilation encompasses hypercapnic central hypoventilation, such as obesity hypoventilation syndrome and eucapnic or hypocapnic central sleep apnoea. Among subjects with eucapnic or hypocapnic central sleep apnoea, several therapeutic options are available for those with Cheyne–Stokes respiration (CSR. CSR is frequent in patients with New York Heart Association stage III and IV chronic heart failure, and in various neurological disorders. In these patients, treatment modalities include optimising cardiac condition and drugs, such as theophylline, acetazolamide and/or oxygen. Ventilatory support, such as nasal continuous positive airway pressure (CPAP, bi-level pressure support, or adaptive servo-ventilation (ASV, has been shown to improve CSR in patients with cardiac failure; however, convincing evidence that nasal CPAP improves life expectancy in these patients is lacking. Nevertheless, the treatment of associated obstructive sleep-disordered breathing is indicated per se, as it may improve cardiac function. There is currently no proof that bi-level ventilation is superior to nasal CPAP. The few available studies that have focused on ASV have shown satisfactory control of CSR in cardiac failure patients. While ASV is not a first-line treatment choice, it appears to be superior to oxygen, CPAP and bi-level pressure ventilation in controlling the apnoea/hypopnea index and probably sleep fragmentation. As yet there are no data on mortality and, as such, firm conclusions cannot be drawn as to the role of ASV in the management of cardiac failure patients suffering from CSR. Obesity-related hypoventilation has increased dramatically over recent decades due to the epidemic increase in obesity in the developed countries. Obesity hypoventilation syndrome predisposes to the development of pulmonary hypertension and cor pulmonale. Noninvasive home ventilation is increasingly applied in obese patients with

    Full Text Available Objective: Phrenic nerve pacing can be used to treat congenital central hypoventilation syndrome (CCHS. We report how the lack of normal vocal cord tone during phrenic paced respiration can result in passive vocal cord collapse and produce obstructive symptoms. Methods: We describe a case of passive vocal cord collapse during phrenic nerve paced respiration in a patient with CCHS. As far as we know, this is the first report of this etiology of airway obstruction. The patient, a 7-year-old with CCHS and normal waking vocal cord movement, continued to require nightly continuous positive airway pressure (CPAP despite successful utilization of phrenic nerve pacers. On direct laryngoscopy, the patient’s larynx was observed while the diaphragmatic pacers were sequentially engaged. Results: No abnormal vocal cord stimulation was witnessed during engaging of either phrenic nerve stimulator. However, the lack of normal inspiratory vocal cord abduction during phrenic nerve-paced respiration resulted in vocal cord collapse and partial obstruction due to passive adduction of the vocal cords through the Bernoulli effect. Bilateral phrenic nerve stimulation resulted in more vocal cord collapse than unilateral stimulation. Conclusions: The lack of vocal cord abduction on inspiration presents a limit to phrenic nerve pacers.

    Full Text Available The mortality rate for respiratory failure resulting from obesity hypoventilation syndrome is high if it requires ventilator management. We describe a case of severe acute respiratory failure resulting from obesity hypoventilation syndrome (BMI, 60.2 kg/m2 successfully treated with venovenous extracorporeal membrane oxygenation (VV-ECMO. During ECMO management, a mucus plug was removed by bronchoscopy daily and 18 L of water was removed using diuretics, resulting in weight loss of 24 kg. The patient was weaned from ECMO on day 5, extubated on day 16, and discharged on day 21. The fundamental treatment for obesity hypoventilation syndrome in morbidly obese patients is weight loss. VV-ECMO can be used for respiratory support until weight loss has been achieved.

    We describe a 2-year-old baby affected by Smith-Magenis syndrome (SMS), due to 17p11.2 deletion, who presented repeated episodes of hemoglobin desaturation during REM sleep. The boy, aged 14 months, presented a phenotype characterized by psychomotor delay, right posterior plagiocephaly, telecanthus, strabismus, upslanting palpebral fissures, broad hypoplastic nasal bridge, short philtrum, deep ring shaped skin creases around the limbs, proximal syndactyly, bilateral hypoacusia. Polysomnographic (PSG) recording showed episodes of REM-related hypoventilation (hemoglobin desaturations without apneas or hypopneas). Sleep disorders are present in almost all the cases of SMS, but very few reports describe the sleep-related respiratory patterns. The finding of REM hypoventilation in SMS does not allow an unequivocal interpretation. It could reflect a subclinical restrictive respiratory impairment or, alternatively, an impairment of central respiratory control during REM sleep. In SMS children, respiratory abnormalities during sleep, and in particular during REM sleep, may cause sleep disruption, reduction of time spent in REM sleep, and daytime sleepiness. We therefore suggest that some sleep abnormalities described in SMS could be consequent to Sleep Disordered Breathing, and in particular to REM hypoventilation. Sleep studies in SMS should include the recording of respiratory parameters.

    Validation of respiratory inductive plethysmography (LifeShirt system) (RIPLS) for tidal volume (VT), minute ventilation (V˙E), and respiratory frequency (fB) was performed among people with untreated obesity hypoventilation syndrome (OHS) and controls. Measures were obtained simultaneously from RIPLS and a spirometer during two tests, and compared using Bland Altman analysis. Among 13 OHS participants (162 paired measures), RIPLS-spirometer agreement was unacceptable for VT: mean difference (MD) 3 mL (1%); limits of agreement (LOA) -216 to 220 mL (±36%); V˙E MD 0.1 L min(-1) (2%); LOA -4.1 to 4.3 L min(-1) (±36%); and fB: MD 0.2 br min(-1) (2%); LOA -4.6 to 5.0 br min(-1) (±27%). Among 13 controls (197 paired measures), RIPLS-spirometer agreement was acceptable for fB: MD -0.1 br min(-1) (-1%); LOA -1.2 to 1.1 br min(-1) (±12%), but unacceptable for VT: MD 5 mL (1%); LOA -160 to 169 mL (±20%) and V˙E: MD 0.1 L min(-1) (1%); LOA -1.4 to 1.5 L min(-1) (±20%). RIPLS produces valid measures of fB among controls but not OHS patients, and is not valid for quantifying respiratory volumes among either group.

    Background Non-invasive ventilation (NIV) is an effective form of treatment in patients with obesity hypoventilation syndrome (OHS) who have concomitant severe obstructive sleep apnoea (OSA). However, there is a paucity of evidence on the efficacy of NIV in patients with OHS without severe OSA. We performed a multicentre randomised clinical trial to determine the comparative efficacy of NIV versus lifestyle modification (control group) using daytime arterial carbon dioxide tension (PaCO2) as the main outcome measure. Methods Between May 2009 and December 2014 we sequentially screened patients with OHS without severe OSA. Participants were randomised to NIV versus lifestyle modification and were followed for 2 months. Arterial blood gas parameters, clinical symptoms, health-related quality of life assessments, polysomnography, spirometry, 6-min walk distance test, blood pressure measurements and healthcare resource utilisation were evaluated. Statistical analysis was performed using intention-to-treat analysis. Results A total of 365 patients were screened of whom 58 were excluded. Severe OSA was present in 221 and the remaining 86 patients without severe OSA were randomised. NIV led to a significantly larger improvement in PaCO2 of −6 (95% CI −7.7 to −4.2) mm Hg versus −2.8 (95% CI −4.3 to −1.3) mm Hg, (p<0.001) and serum bicarbonate of −3.4 (95% CI −4.5 to −2.3) versus −1 (95% CI −1.7 to −0.2 95% CI)  mmol/L (p<0.001). PaCO2 change adjusted for NIV compliance did not further improve the inter-group statistical significance. Sleepiness, some health-related quality of life assessments and polysomnographic parameters improved significantly more with NIV than with lifestyle modification. Additionally, there was a tendency towards lower healthcare resource utilisation in the NIV group. Conclusions NIV is more effective than lifestyle modification in improving daytime PaCO2, sleepiness and polysomnographic parameters. Long

    Positive airway pressure (PAP) treatment has been shown to have a modest effect on ambulatory blood pressure (BP) in patients with obstructive sleep apnea (OSA). However, there is a paucity of data on the effect of PAP therapy on rapid, yet significant, BP swings during sleep, particularly in obesity hypoventilation syndrome (OHS). The present study hypothesizes that PAP therapy will improve nocturnal BP on the first treatment night (titration PAP) in OHS patients with underlying OSA, and that these improvements will become more significant with 6 wk of PAP therapy. Seventeen adults (7 men, 10 women; age 50.4 ± 10.7 years, BMI 49.3 ± 2.4 kg/m(2)) with OHS and clinically diagnosed OSA participated in three overnight laboratory visits that included polysomnography and beat-to-beat BP monitoring via finger plethysmography. Six weeks of PAP therapy, but not titration PAP, lowered mean nocturnal BP. In contrast, when nocturnal beat-to-beat BPs were aggregated into bins consisting of at least three consecutive cardiac cycles with a >10 mmHg BP surge (i.e., Δ10-20, Δ20-30, Δ30-40, and Δ>40 mmHg), titration, and 6-wk PAP reduced the number of BP surges per hour (time × bin, P < 0.05). PAP adherence over the 6-wk period was significantly correlated to reductions in nocturnal systolic (r = 0.713, P = 0.001) and diastolic (r = 0.497, P = 0.043) BP surges. Despite these PAP-induced improvements in nocturnal beat-to-beat BP surges, 6 wk of PAP therapy did not alter daytime BP. In conclusion, PAP treatment reduces nocturnal beat-to-beat BP surges in OHS patients with underlying OSA, and this improvement in nocturnal BP regulation was greater in patients with higher PAP adherence.

    Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

    Full Text Available The Chiari malformation type I (CM-I has been associated with sleep-disordered breathing, especially central sleep apnea syndrome. We report the case of a 44-year-old female with CM-I who was referred to our sleep laboratory for suspected sleep apnea. The patient had undergone decompressive surgery 3 years prior. An arterial blood gas analysis showed hypercapnia. Polysomnography showed a respiratory disturbance index of 108 events/h, and all were central apnea events. Treatment with adaptive servo-ventilation was initiated, and central apnea was resolved. This report demonstrates the efficacy of servo-ventilation in the treatment of central sleep apnea syndrome associated with alveolar hypoventilation in a CM-I patient with a history of decompressive surgery.

    Anatomic, functional, and neurochemical imaging studies have provided new investigative tools in the study of central pain. High-resolution imaging studies allow for precise determination of lesion location, whereas functional neuroimaging studies measure pathophysiologic consequences of injury to the central nervous system. Additionally, magnetic resonance spectroscopy evaluates lesion-induced neurochemical changes in specific brain regions that may be related to central pain. The small number of studies to date precludes definitive conclusions, but the recent findings provide information that either supports or refutes current hypotheses and can serve to generate new ideas.

    Full Text Available Tanto SHO como as doenças neuromusculares estão relacionadas à hipoventilação durante o sono. Define-se SHO como a combinação de obesidade, hipercapnia e hipoxemia crônica durante a vigília que se agrava durante o sono. Em 90% dos casos, SHO está associada à apneia obstrutiva do sono. O diagnóstico baseia-se na presença de hipoventilação diurna e hipertensão pulmonar que não são justificadas por alterações da função pulmonar. A mortalidade dos pacientes com SHO é maior que aquela de pacientes sem hipoventilação e controlados para obesidade. As doenças neuromusculares são representadas principalmente pelas distrofias musculares. A progressão para insuficiência respiratória crônica surge como consequência da fraqueza dos músculos respiratórios e da limpeza inadequada das vias aéreas, causando atelectasias e pneumonias. Quando há uma redução maior que 50% da forca muscular respiratória, ocorre uma diminuição na CV. A medida do pico de fluxo da tosse Sleep hypoventilation is seen in patients with neuromuscular disease, as well as in those with obesity hypoventilation syndrome (OHS, which is defined as the combination of obesity, chronic hypercapnia, and hypoxemia during wakefulness that is aggravated during sleep. In 90% of cases, OHS is accompanied by obstructive sleep apnea. The diagnosis of OHS is based on hypoventilation and pulmonary hypertension that cannot be explained by alterations in pulmonary function. The mortality of patients with OHS is greater than is that of obese patients without hypoventilation. The principal neuromuscular diseases associated with OHS are the muscular dystrophies. The progression to chronic respiratory failure results from respiratory muscle weakness and impaired airway secretion clearance, causing atelectasis and pneumonia. With a decrease of greater than 50% in respiratory muscle strength, there is a reduction in VC. Cough peak flow < 160 L/min is associated with impaired

    Effectiveness of treatment with domiciliary nocturnal noninvasive positive pressure ventilation is analyzed in a group of patients with chronic alveolar hypoventilation of different etiologies. It was applied with two levels of pressure (BiPAP) via nasal mask. Criteria for evaluation were symptomatology and improvement in gas exchange. Data were analyzed by Student t tests. A total of 13 patients were included, mean age 55.7 range 20 to 76 years (5 male 8 female). Main diagnosis was tuberculosis in 6, four of them having had surgical procedure (thoracoplasty 2, frenicectomy 1 and neumonectomy 1), myopathy 3 (myasthenia gravis 1, muscular dystrophy 1 and diaphragmatic paralysis 1), obesity-hypoventilation syndrome 1, escoliosis 1, bronchiectasis 1 and cystic fibrosis 1. These last two patients were on waiting list for lung transplantation. At the moment of consultation, the symptoms were: dysnea 13/13 (100%), astenia 13/13 (100%), hypersomnolency 10/13 (77%), cephalea 9/13 (69%), leg edema 6/13 (46%), loss of memory 6/13 (46%). Regarding gas exchange, they showed hypoxemia and hypercapnia. Mean follow up was of 2.2 years (range 6 months to 4 years). Within the year, all 13 patients became less dyspneic. Astenia, hypersomnolency, cephalea, leg edema and memory loss disappeared. Improvement in gas exchange was: PaO2/FiO2 from 269 +/- 65.4 (basal) to 336.7 +/- 75.3 post-treatment (p = 0.0018). PaCO2 from 70.77 +/- 25.48 mmHg (basal) to 46.77 +/- 8.14 mmHg (p = 0.0013). Ventilatory support was discontinued en 5 patients: three because of pneumonia requiring intubation and conventional mechanical ventilation, two of them died and one is still with tracheostomy; One patient with bronchiectasis and one with cystic fibrosis were transplanted. The remaining eight patients are stable. In conclusion, chronic alveolar hypoventilation can be effectively treated with domiciliary nocturnal noninvasive ventilation.

    Full Text Available Background. The accumulation of risk factors for central retinal artery occlusion can be seen in a single person and might be explained by the metabolic syndrome. Case report. We presented the case of a 52-year-old man with no light perception in his right eye. The visual loss was monocular and painless, fundoscopy showed central retinal artery occlusion and the laboratory investigation showed the raised erythrocyte sedimentation rate of 105 mm/h and the raised C-reactive protein of 22 mg/l. Specific laboratory investigations and fluorescein angiography excluded the presence of vasculitis, collagen vascular diseases, hypercoagulable state and antiphospholipid syndrome. Conclusion. The patient met all the five of the National Cholesterol Education Program (NCEP criteria for the metabolic syndrome: hypertension, abnormal lipid profile, abnormal glucose metabolism, obesity and hyperuricemia. Measurement of C-reactive protein is useful for the assessment of therapeutic systemic effect on any abnormality in the metabolic syndrome. Individual therapy for all risk factors in the metabolic syndrome is necessary to prevent complications such as cardiovascular, retinal vascular diseases and stroke.

    Sheehan's syndrome refers to the occurrence of hypopituitarism after delivery, usually preceded by postpartum hemorrhage. The condition still continues to be a common cause of hypopituitarism in developing countries like India. The disorder usually presents with anterior pituitary failure with preservation of posterior pituitary functions. Posterior pituitary dysfunction in the form of central diabetes insipidus is rare in patients with Sheehan's syndrome. We describe the clinical course of a young lady who after her sixth childbirth developed severe postpartum hemorrhage followed by development of panhypopituitarism which was confirmed by hormonal investigation and demonstration of empty sella on imaging. In addition, she developed Polyuria. The water deprivation test and response to vasopressin test results indicated central diabetes insipidus. She needed oral desmopressin on a continuous basis to control polyuria.

    Full Text Available Pain can be broadly divided into 3 classes, including nociceptive or inflammatory pain (protective, neuropathic (pathological, occurring after damage to the nervous system, or centralized (pathological, due to abnormal function but with no damage or inflammation to the nervous system. The latter has been posited to occur when descending analgesic pathways are attenuated and/or glutamatergic transmission is facilitated. Additionally, this “pain prone phenotype” can be associated with early life trauma and a suboptimal response to opiates. This article will review the relationships between centralized pain syndromes (ie, fibromyalgia, chronic low back pain, childhood sexual abuse, and opiate misuse. Finally, treatment implications, potentially effecting primary care physicians, will be discussed.

    Full Text Available Abstract Solitary median maxillary central incisor syndrome (SMMCI is a complex disorder consisting of multiple, mainly midline defects of development resulting from unknown factor(s operating in utero about the 35th–38th day(s from conception. It is estimated to occur in 1:50,000 live births. Aetiology is uncertain. Missense mutation in the SHH gene (I111F at 7q36 may be associated with SMMCI. The SMMCI tooth differs from the normal central incisor, in that the crown form is symmetric; it develops and erupts precisely in the midline of the maxillary dental arch in both primary and permanent dentitions. Congenital nasal malformation (choanal atresia, midnasal stenosis or congenital pyriform aperture stenosis is positively associated with SMMCI. The presence of an SMMCI tooth can predict associated anomalies and in particular the serious anomaly holoprosencephaly. Common congenital anomalies associated with SMMCI are: severe to mild intellectual disability, congenital heart disease, cleft lip and/or palate and less frequently, microcephaly, hypopituitarism, hypotelorism, convergent strabismus, oesophageal and duodenal atresia, cervical hemivertebrae, cervical dermoid, hypothyroidism, scoliosis, absent kidney, micropenis and ambiguous genitalia. Short stature is present in half the children. Diagnosis should be made by eight months of age, but can be made at birth and even prenatally at 18–22 weeks from the routine mid-trimester ultrasound scan. Management depends upon the individual anomalies present. Choanal stenosis requires emergency surgical treatment. Short stature may require growth hormone therapy. SMMCI tooth itself is mainly an aesthetic problem, which is ideally managed by combined orthodontic, prosthodontic and oral surgical treatment; alternatively, it can be left untreated.

    Full Text Available Fungal infections of the central nervous system (CNS are being increasingly diagnosed both in immunocompromised and immunocompetent individuals. Sinocranial aspergillosis is more frequently described from countries with temperate climates, more often in otherwise immunocompetent individuals. The clinical syndromes with which fungal infections of the CNS can present are protean and can involve most part of the neuroaxis. Certain clinical syndromes are specific for certain fungal infections. The rhinocerebral form is the most common presenting syndrome with zygomycosis and skull-base syndromes are often the presenting clinical syndromes in patients with sinocranial aspergillosis. Subacute and chronic meningitis in patients with HIV infection is more likely to be due to cryptococcal infection. Early recognition of the clinical syndromes in an appropriate clinical setting is the first step towards achieving total cure in some of these infections.

    Full Text Available Sjogren’s syndrome is a slowly progressive autoimmune disease. Neurological involvement occurs in approximately 20-25% cases in Sjogren’s syndrome. 87% of the neurological involvement is peripheral nervous system, almost 13% in the form of central nervous system involvement. Affected central nervous system may show similar clinical and radiological findings as in multiple sclerosis (MS. In this paper, a 43-year-old patient is discussed who was referred with the complaint of dizziness, there was MS- like lesions in brain imaging studies and was diagnosed with Sjogren’s syndrome. MS- like clinical and radiologic tables can be seen, albeit rarely in Sjogren’s syndrome. In these cases, early diagnosis and early treatment for the sjögren has a great importance for the prognosis of the disease.

  11. Hypoventilation in chronic mountain sickness: a mechanism to preserve energy.

    Chronic Mountain Sickness (CMS) patients have repeatedly been found to hypoventilate. Low saturation in CMS is attributed to hypoventilation. Although this observation seems logical, a further understanding of the exact mechanism of hypoxia is mandatory. An exercise study using the Bruce Protocol in CMS (n = 13) compared to normals N (n = 17), measuring ventilation (VE), pulse (P), and saturation by pulse oximetry (SaO(2)) was performed. Ventilation at rest while standing, prior to exercise in a treadmill was indeed lower in CMS (8.37 l/min compared with 9.54 l/min in N). However, during exercise, stage one through four, ventilation and cardiac frequency both remained higher than in N. In spite of this, SaO(2) gradually decreased. Although CMS subjects increased ventilation and heart rate more than N, saturation was not sustained, suggesting respiratory insufficiency. The degree of veno-arterial shunting of blood is obviously higher in the CMS patients both at rest and during exercise as judged from the SaO(2) values. The higher shunt fraction is due probably to a larger degree of trapped air in the lungs with uneven ventilation of the CMS patients. One can infer that hypoventilation at rest is an energy saving mechanism of the pneumo-dynamic and hemo-dynamic pumps. Increased ventilation would achieve an unnecessary high SaO(2) at rest (low metabolism). This is particularly true during sleep.

    Depending on the temporal course, three forms of vertigo syndrome can be differentiated: 1) vertigo attacks, e.g. benign paroxysmal positional vertigo (BPPV), Menière's disease and vestibular migraine, 2) acute spontaneous vertigo lasting for days, e.g. acute unilateral vestibulopathy, brainstem or cerebellar infarction and 3) symptoms lasting for months or years, e.g. bilateral vestibulopathy and functional vertigo. The specific therapy of the various syndromes is based on three principles: 1) physical treatment with liberatory maneuvers for BPPV and balance training for vestibular deficits, 2) pharmacotherapy, e.g. for acute unilateral vestibulopathy (corticosteroids) and Menière's disease (transtympanic administration of gentamicin or steroids and high-dose betahistine therapy); placebo-controlled pharmacotherapy studies are currently being carried out for acute unilateral vestibulopathy, vestibular paroxysmia, prophylaxis of BPPV, vestibular migraine, episodic ataxia type 2 and cerebellar ataxia; 3) psychotherapy for functional dizziness.

    Sheehan's syndrome occurs as a result of ischaemic pituitary necrosis due to severe postpartum haemorrhage. Improvements in obstetrical care have significantly reduced its incidence in developed countries, but postpartum pituitary infarction remains a common cause of hypopituitarism in developing countries. We report a case of severe postpartum haemorrhage followed by headache, central diabetes insipidus and failure to lactate, which prompted us to investigate and identify both anterior and posterior pituitary deficiency compatible with Sheehan's syndrome. A timely diagnosis allowed us to implement an adequate treatment and follow-up plan, which are known to improve clinical status and patient outcome.

    Full Text Available Rapid-onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation (ROHHAD is a rare and complex pediatric disorder . Children typically show ROHHAD after the first years of life with rapid weight gain and subsequently autonomic nervous system dysregulation (altered pain perception, pupillary dysfunction, hypothermia and bradycardia; alveolar hypoventilation with risk of cardiorespiratory arrest and hypothalamic dysfunction (central diabetes insipidus, hypothyroidism, growth hormone and corticotrophin deficiency. Tumours of neural crest origin, such as ganglioneuroblastoma and ganglioneuronoma, are reported in 33% of the patients and may be found in the chest or abdomen. Here we describe two girls who presented with rapid weight gain, at the age of 5 and 9 years respectively. The first was admitted due to obesity and central hypothyroidism. After two months she rapidly developed a clinical picture characterized by thermal dysregulation, hypodipsia and severe hypernatriemia, hypertrigliceridemia, alveolar hypoventilation supported by mechanical ventilation. The second presented with rapid-onset obesity and a mild hyperprolactinemia. After three months of follow- up she was admitted due to a clinical picture of hypothermia, seizures and hyponatremia. Subsequentely she developed altered water balance (severe hypernatremia and severe hypoventilation . Chest CT and MR imaging showed a posterior mediastinal mass. Endocrinological investigation showed corticotrophin deficiency and central hypothyroidism treated with specific replacement therapies. Conclusions: On the basis of our experiences we can infer that it is necessary perform specific further investigations of hypothalamic function in all the children with rapid onset obesity in order to early prevent the catastrophic consequences that may occur in this syndrome.

    Central neurogenic diabetes insipidus, syndrome of inappropriate secretion of antidiuretic hormone, and cerebral salt-wasting syndrome are secondary events that affect patients with traumatic brain injury. All 3 syndromes affect both sodium and water balance; however, they have differences in pathophysiology, diagnosis, and treatment. Differentiating between hypernatremia (central neurogenic diabetes insipidus) and the 2 hyponatremia syndromes (syndrome of inappropriate secretion of antidiuretic hormone, and cerebral salt-wasting syndrome) is critical for preventing worsening neurological outcomes in patients with head injuries.

    Full Text Available Individuals with metabolic syndrome (MetS; i.e. 3 of 5 of the following risk factors (RFs: elevated blood pressure, waist circumference, triglycerides, blood glucose or reduced HDL are thought to be prone to serious cardiovascular disease and there is debate as to whether the disease begins in the peripheral vasculature or centrally. This study investigates hemodynamics, cardiac function/morphology, as well as mechanical properties of the central (heart, carotid artery and peripheral (total peripheral resistance, forearm vascular bed vasculature in individuals without (1-2 RFs; n=28, or with (≥3 RFs; n=46 MetS. After adjustments for statin and blood pressure medication use, those with MetS had lower mitral valve E/A ratios (<3 RFs: 1.24±0.07; ≥3 RFs: 1.01±0.04; P=0.025, and higher total peripheral resistance index (<3 RFs: 48±2 mmHg/L/min/m2; ≥3 RFs: 53±2 mmHg/L/min/m2; P=0.04. There were no differences in heart size, carotid artery measurements, cardiovagal baroreflex sensitivity, pulse wave velocity, stroke volume index, or cardiac output index due to MetS after adjustments for statin and blood pressure medication use. In a separate analysis, the use of statins was associated with increased inertia in the brachial vascular bed, increased HbA1c and decreased LDL cholesterol. The independent use of anti-hypertensive medication was associated with decreased predicted VO2max, triglycerides, diastolic blood pressure, interventricular septum thickness, calculated left ventricle mass, left ventricle posterior wall thickness, and left ventricle pre-ejection period, but increased carotid stiffness, HDL cholesterol, and heart rate. These data imply that both a central cardiac effect and a peripheral effect of vascular resistance are expressed in MetS. These data also indicate that variance in between-group responses due to pharmacological treatments are important factors to consider in studying cardiovascular changes in these individuals.

  5. Should waist circumference be replaced by index of central obesity (ICO) in definition of metabolic syndrome?

    Parikh, R; Mohan, V; Joshi, S

    2012-01-01

    Waist circumference has been widely used as the parameter of central obesity in defining metabolic syndrome. Global consensus definition of metabolic syndrome has suggested various race- and gender-specific cutoffs of waist circumference for quantifying central obesity. We have earlier proposed that using index of central obesity (ICO), the need for race- and gender-specific cutoffs may be obviated. We propose that waist circumference be supplanted with index of central obesity in all definitions of metabolic syndrome. Using index of central obesity a common cutoff of 0.5 applicable across races and genders might be obtained. Moreover, it will enhance the sensitivity of definition by diagnosing subjects who are shorter than general population. Among 258 male and 242 female diabetic patients, subjects with metabolic syndrome (defined as per gender-specific waist circumference cutoffs), were found to have a common lower range of index of central obesity suggesting that a common cutoff of waist circumference may be obtained. In another study from National Health and Nutrition Examination Survey database, replacing index of central obesity with waist circumference was found to enhance the specificity and sensitivity of definition of metabolic syndrome.

    2014-04-01

    Central nervous system symptoms in patients with primary Sjogren`s syndrome are rare. They can present as extraglandular manifestations and require a differential diagnosis from multiple sclerosis. Due to a variety of presentations, Sjogren`s syndrome with neurologic involvement may be difficult to diagnose. Here, we report a case of a 75-year-old woman who was first diagnosed with multiple sclerosis in 2010, but who was subsequently diagnosed with primary Sjogren`s syndrome 2 years later after showing signs of atypical neurologic manifestations. Therefore, primary Sjogren`s syndrome should be suspected in patients who present with atypical clinical and radiologic neurologic manifestations.

    Full Text Available Abstract Background High levels of exhaled carbon monoxide (eCO are a marker of airway or lung inflammation.

Methods Ten healthy volunteers were trained to achieve sustained end-tidal CO2 (etCO2 concentrations of 30 (hyperventilation, 40 (normoventilation, and 50 mmHg (hypoventilation. As soon as target etCO2 values were achieved for 120 sec, exhaled breath was analyzed for eCO with a photoacoustic spectrometer. At etCO2 values of 30 and 40 mmHg exhaled breath was sampled both after a deep inspiration and after a normal one. All measurements were performed in two different environmental conditions: A ambient CO concentration = 0.8 ppm and B ambient CO concentration = 1.7 ppm. Results During normoventilation, eCO mean (standard deviation was 11.5 (0.8 ppm; it decreased to 10.3 (0.8 ppm during hyperventilation (p 2 changes (hyperventilation: 10% Vs 25% decrease; hypoventilation 3% Vs 25% increase.

    Central diabetes insipidus (CDI) could occurs in patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML), because of infiltration of leukemic cells into the neurohypophysis or some other reason and it is closely associated with abnormalities of chromosome 7. We report a case of MDS with abnormalities of chromosome 7, presenting as CDI followed by deterioration of polyuria and hyponatremia with a decreased extracellular fluid volume. Magnetic resonance imaging (MRI) revealed symmetrically enhanced lesions in the hypothalamus. Fludrocortisone treatment normalized his serum sodium level and cerebral salt wasting syndrome (CSWS) was suspected.

    The aim of this study was to investigate whether bilateral widespread pressure hypersensitivity exists in patients with unilateral carpal tunnel syndrome. A total of 20 females with carpal tunnel syndrome (aged 22-60 years), and 20 healthy matched females (aged 21-60 years old) were recruited. Pressure pain thresholds were assessed bilaterally over median, ulnar, and radial nerve trunks, the C5-C6 zygapophyseal joint, the carpal tunnel and the tibialis anterior muscle in a blinded design. The results showed that pressure pain threshold levels were significantly decreased bilaterally over the median, ulnar, and radial nerve trunks, the carpal tunnel, the C5-C6 zygapophyseal joint, and the tibialis anterior muscle in patients with unilateral carpal tunnel syndrome as compared to healthy controls (all, P < 0.001). Pressure pain threshold was negatively correlated to both hand pain intensity and duration of symptoms (all, P < 0.001). Our findings revealed bilateral widespread pressure hypersensitivity in subjects with carpal tunnel syndrome, which suggest that widespread central sensitization is involved in patients with unilateral carpal tunnel syndrome. The generalized decrease in pressure pain thresholds associated with pain intensity and duration of symptoms supports a role of the peripheral drive to initiate and maintain central sensitization. Nevertheless, both central and peripheral sensitization mechanisms are probably involved at the same time in carpal tunnel syndrome.

    Central diabetes insipidus, a common consequence of acute central nervous system injury, causes hypernatremia; cerebral salt wasting syndrome can cause hyponatremia. The two conditions occurring simultaneous are rarely described in pediatric patients. Pediatric cases of combined diabetes insipidus and cerebral salt wasting after acute central nervous system injury between January 2000 and December 2007 were retrospectively reviewed, and clinical characteristics were systemically assessed. Sixteen patients, aged 3 months to 18 years, met study criteria: 11 girls and 5 boys. The most common etiologies were severe central nervous system infection (n = 7, 44%) and hypoxic-ischemic event (n = 4, 25%). In 15 patients, diabetes insipidus was diagnosed during the first 3 days after acute central nervous system injury. Onset of cerebral salt wasting syndrome occurred 2-8 days after the onset of diabetes insipidus. In terms of outcome, 13 patients died (81%) and 3 survived under vegetative status (19%). Central diabetes insipidus and cerebral salt wasting syndrome may occur after acute central nervous system injury. A combination of both may impede accurate diagnosis. Proper differential diagnoses are critical, because the treatment strategy for each entity is different.

    2016-02-01

    Thrombotic manifestations of antiphospholipid syndrome (APS) are well known, and various non-stroke neuro-psychiatric manifestations (NPMs) have also been consistently described, but their place in APS remains unclear. Some syndromes, such as migraine or cognitive dysfunction, are frequently described in APS, whereas others, like seizure, multiple sclerosis-like symptoms, transverse myelitis, movement disorders, or psychiatric symptoms, are rarely found. Overlap with other autoimmune diseases, in particular with systemic lupus erythematosus, the lack of large sample size prospective studies, and discrepancies in antiphospholipid antibody (aPL) determinations complicate the study of the relationship between those disorders and aPL/APS. This review article aimed to summarize updated data on pathophysiologic, epidemiologic, and radiologic findings about non-stroke NPM described in primary APS and aPL-positive patients without overlap of other autoimmune diseases.

    The Riley-Day syndrome is characterized by a dysfunction of the autonomous nervous system, sensory disturbances, neurological disorders, psychical anomalies and important ophthalmological symptoms, such as absence of tears, corneal anaesthesia, keratinized conjunctiva and cornea; myosis after instillation of methacholine. The diagnosis is based on the absence of fungiform papillae of the tongue and the absence of reaction after intradermic injection of histamine. The inheritance is autosomal recessive. The disease results probably from an enzymatic insufficiency.

    Dextromethorphan, a noncompetitive blocker of the N-methyl-D-aspartate (NMDA) type of glutamate receptor, at 45, 60 and 75 mg/kg, ip doses induced a behavioural syndrome characterised by reciprocal forepaw treading, lateral head-weaving, hind-limb abduction and flat body posture. Such type of behavioural syndrome is induced by 8-hydroxy-2- (di-n-propylamino) tetralin (8-OH-DPAT) by directly stimulating the central postsynaptic 5-hydroxytryptamine (5-HT, serotonin) receptors of the 5-HT1A type. Pretreatment with buspirone (5, 10 mg/kg, ip) and l-propranolol (10, 20 mg/kg, ip) antagonised the behavioural syndrome induced by 8-OH-DPAT and dextromethorphan. Pretreatment with p-chlorophenylalanine (100 mg/kg/day x 4 days) antagonised the behavioural syndrome induced by dextromethorphan and dexfenfluramine but had no significant effect on 8-OH-DPAT induced behavioural syndrome. This indicates that dextromethorphan induces the behavioural syndrome by releasing 5-HT from serotonergic neurons with resultant activation of the postsynaptic 5-HT1A receptors by the released 5-HT. Pretreatment with fluoxetine (10 mg/kg, ip) significantly potentiated the behavioural syndrome induced by dextromethorphan and 5-hydroxytryptophan but significantly antagonised dexfenfluramine induced behavioural syndrome. This indicates that dextromethorphan releases 5-HT by a mechanism which differs from that of dexfenfluramine. Dextromethorphan may be releasing 5-HT by blocking the NMDA receptors and thereby counteracting the inhibitory influence of l-glutamate on 5-HT release.

    Full Text Available Introduction: The various diagnostic classifications in the literature concur as regards the important role of abdominal obesity in the onset and progression of metabolic syndrome. Accordingly, this study was aimed at clarifying whether central obesity measurements assessed by dual X-ray absorptiometry (DXA may predict metabolic syndrome in Spanish postmenopausal women. Material and methods: This historical cohort study included a total of 1326 postmenopausal women aged > 45 years old who had routinely undergone DXA to measure their bone mineral density between january 2006 and january 2011. The regions of interest (ROI envisaged in our study by using DXA were the lumbar regions L1-L4 and L4-L5. At the same time, they underwent a complete medical examination including personal medical history assessment, biochemical blood analysis, blood pressure measurement and anthropometrical evaluation. Metabolic syndrome was diagnosed attending to the criteria established by National Cholesterol Education Program Adult Treatment Panel III (NECP-ATP-III. Results: During the observation period, 537 women, representing 40.5% of the total studied, met the diagnostic criteria for metabolic syndrome. L1-L4 and L4-L5 abdominal fat mass determinations were associated with the development of metabolic syndrome in all regression models tested, showing an increasing gradient from the lowest to highest quintile. Conclusion: Central adiposity measurements assessed by DXA, especially L1-L4 region of interest, could be considered a powerful predictor of metabolic syndrome in postmenopausal women.

    Painful sensations are some of the most frequent complaints of patients who are admitted to local medical clinics. Persistent pain varies according to its causes, often resulting from local tissue damage or inflammation. Central somatosensory pathway lesions that are not adequately relieved can consequently cause central pain syndrome or central neuropathic pain. Research on the molecular mechanisms that underlie this pathogenesis is important for treating such pain. To date, evidence suggests the involvement of ion channels, including adenosine triphosphate (ATP)-gated cation channel P2X receptors, in central nervous system pain transmission and persistent modulation upon and following the occurrence of neuropathic pain. Several P2X receptor subtypes, including P2X2, P2X3, P2X4, and P2X7, have been shown to play diverse roles in the pathogenesis of central pain including the mediation of fast transmission in the peripheral nervous system and modulation of neuronal activity in the central nervous system. This review article highlights the role of the P2X family of ATP receptors in the pathogenesis of central neuropathic pain and pain transmission. We discuss basic research that may be translated to clinical application, suggesting that P2X receptors may be treatment targets for central pain syndrome.

    Abstract A retrospective study was conducted at Tongji Forensic Medical Center in Hubei (TFMCH) from 1999 to 2014. Forty-nine cases of sudden unexplained nocturnal death syndrome (SUNDS) were collected. The SUNDS rate was 1.0% in the total number of cases, in which an incidence was fluctuating over the years. Interestingly, April and January, and 3:00 to 6:00 am were the peak months and times of death. Among the decedents, farmers and migrant workers accounted for 67.3%. The syndrome predominantly attacked males in their 30s. One victim had sinus tachycardia. Thirteen victims (26.5%) were witnessed and had abnormal symptoms near death. Macroscopically, compared to sudden noncardiac deaths, the weights of brain, heart, and lungs had no statistical difference in SUNDS. Microscopically, the incidence of lung edema (45 cases, 91.8%) was significantly higher in SUNDS group than in the control group (27 cases, 55.1%). 82.9% of 35 SUNDS cases examined displayed minor histological anomalies of the cardiac conduction system (CCS), including mild or moderate fatty, fibrous or fibrofatty tissue replacement, insignificant stenosis of node artery, and punctate hemorrhage in the node area. These findings suggested that minor CCS abnormalities might be the substrates for some SUNDS deaths. Therefore, SUNDS victims might suffer ventricular fibrillation and acute cardiopulmonary failure before death. Further in-depth studies are needed to unveil the underlying mechanisms of SUNDS.

    Indwelling central venous catheters have been reported to increase the risk of superior venous cava (SVC) syndrome. This case report describes the development of acute SVC syndrome in a 28-year-old woman with end-stage renal disease implanted with a left-side hemodialysis reliable outflow graft and a right-side double lumen hemodialysis catheter via internal jugular veins. Her symptoms were not alleviated after catheter removal and systemic anticoagulation therapy. She was eventually treated with catheter-directed thrombolysis and a predischarge computer tomographic venogram on postthrombolytic procedure day 7 showed patent central veins and patient remained asymptomatic. This case demonstrates that catheter-directed thrombolysis can be safely employed to treat refractory catheter-induced acute SVC syndrome in end-stage renal disease patients.

    The purpose of this investigation was to describe the causes, clinical pattern, and treatment of cerebral salt wasting syndrome in children with acute central nervous system injury. This retrospective study focused on patientscerebral salt wasting syndrome, over a period of 7 years, in the pediatric intensive care unit of a tertiary care hospital. Selection criteria included evidence of hyponatremia (serum sodium120 mEq/L), and volume depletion. Fourteen patients were identified with cerebral salt wasting syndrome, 12 after a neurosurgical procedure (8 brain tumor, 4 hydrocephalus) and 2 after severe brain trauma. In 11 patients the cerebral salt wasting syndrome was diagnosed during the first 48 hours of admission. Prevalence of cerebral salt wasting syndrome in neurosurgical children was 11.3/1000 surgical procedures. The minimum sodium was 122+/-7 mEq/L, the maximum urine osmolarity 644+/-59 mOsm/kgH2O. The maximum sodium supply was 1 mEq/kg/h (range, 0.1-2.4). The mean duration of cerebral salt wasting syndrome was 6+/-5 days (range 1-9). In conclusion, cerebral salt wasting syndrome can complicate the postoperative course of children with brain injury; it is frequently present after surgery for brain tumors and hydrocephalus and in patients with severe head trauma. Close monitoring of salt and fluid balance is essential to prevent severe neurologic and hemodynamic complications.

    2014-10-01

    Solid organ transplant recipients have a high incidence of central nervous system (CNS) complications, including both focal and diffuse neurologic deficits. In the immunocompromised host, the initial clinical evaluation must focus on both life-threatening CNS infections and vascular or anatomic lesions. The clinical signs and symptoms of CNS processes are modified by the immunosuppression required to prevent graft rejection. In this population, these etiologies often coexist with drug toxicities and metabolic abnormalities that complicate the development of a specific approach to clinical management. This review assesses the multiple risk factors for CNS processes in solid organ transplant recipients and establishes a timeline to assist in the evaluation and management of these complex patients.

    Full Text Available Abstract Objective To analyze the prevalence of diagnosed and suspected autoinflammatory diseases in Eastern and Central European (ECE countries, with a particular interest on the diagnostic facilities in these countries. Methods Two different strategies were used to collect data on patients with periodic fever syndromes from ECE countries- the Eurofever survey and collection of data with the structured questionnaire. Results Data from 35 centers in 14 ECE countries were collected. All together there were 11 patients reported with genetically confirmed familial Mediterranean fever (FMF, 14 with mevalonate-kinase deficiency (MKD, 11 with tumor necrosis factor receptor associated periodic syndrome (TRAPS and 4 with chronic infantile neurological cutaneous and articular syndrome (CINCA. Significantly higher numbers were reported for suspected cases which were not genetically tested. All together there were 49 suspected FMF patients reported, 24 MKD, 16 TRAPS, 7 CINCA and 2 suspected Muckle-Wells syndrome (MWS patients. Conclusions The number of genetically confirmed patients with periodic fever syndromes in ECE countries is very low. In order to identify more patients in the future, it is important to organize educational programs for increasing the knowledge on these diseases and to establish a network for genetic testing of periodic fever syndromes in ECE countries.

    Although most of the central nervous system tumours are sporadic, rarely they are associated with familial tumour syndromes. These disorders usually present with an autosomal dominant inheritance and neoplasia develops at younger age than in sporadic cases. Most of these tumours are bilateral, multiplex or multifocal. The causative mutations occur in genes involved in cell cycle regulation, cell growth, differentiation and DNA repair. Studying these hereditary cancer predisposition syndromes associated with nervous system tumours can facilitate the deeper understanding of the molecular background of sporadic tumours and the development of novel therapeutic agents. This review is an update on hereditary tumour syndromes with nervous system involvement with emphasis on molecular genetic characteristics and their clinical implications.

    Full Text Available Ramsay Hunt syndrome associated with varicella zoster virus reactivation affecting the central nervous system is rare. We describe a 55-year-old diabetic female who presented with gait ataxia, right peripheral facial palsy, and painful vesicular lesions involving her right ear. Later, she developed dysmetria, fluctuating diplopia, and dysarthria. Varicella zoster virus was detected in the cerebrospinal fluid by polymerase chain reaction. She was diagnosed with Ramsay Hunt syndrome associated with spread to the central nervous system. Her facial palsy completely resolved within 48 hours of treatment with intravenous acyclovir 10 mg/kg every 8 hours. However, cerebellar symptoms did not improve until a tapering course of steroid therapy was initiated.

    The association of paroxysmal hemicrania with trigeminal neuralgia (TN) has been described and called paroxysmal hemicrania-tic syndrome (PH-tic). We report the case of a patient diagnosed as having chronic PH-tic (CPH-tic) syndrome as a clinically isolated syndrome of the central nervous system (CNS) (CIS).A forty year old woman was admitted to our hospital suffering from right facial pain for the last 2 years. The attacks were paroxysmal, neuralgiform, consisting of throb-like sensations, which developed spontaneously or were triggered by different stimuli in right facial (maxilar and mandibular) areas. Parallel with those, she felt a throbbing orbital and frontal pain with homolateral autonomic symptoms such as conjunctival injection, lacrimation, and the feeling that the ear on the same side was full. This pain lasted most often between 15 and 20 minutes. Beyond hemifacial hypoesthesia in the region of right maxilar and mandibular nerve, the other neurological finding was normal. Magnetic resonance imaging (MRI) study showed a T2-weighted multiple hyperintense paraventricular lesion and hyperintense lesion in the right trigeminal main sensory nucleus and root inlet, all of them being hypointense on T1-weighted image. All of these lesions were hypointense in gadolinium-enhanced T1-weighted images. Neurophysiological studies of trigeminal nerve (somatosensory evoked potentials and blink reflex) correlated with MRI described lesions. The patient's pain bouts were improved immediately after treatment with indomethacin, and were completely relieved with lamotrigine for a longer period. According to the actual McDonald's criteria, clinical state was defined as CIS which was clinically presented by CPH-tic syndrome.Even though it is a clinical rarity and its etiology is usually idiopathic, CPH-tic syndrome can also be symptomatic. When dealing with symptomatic cases, like the one described here, when causal therapy is not possible due to the nature of the primary

    To leptospirosis is the commonest spirocheatal infection in the tropical and temperate countries of Indian sub-continent and Africa and the most common zoonosis worldwide. The protean manifestation of this infectious disease is a challenge for practising clinicians across the world. In poor developing countries, at most clinical suspicion it is essential in the diagnosis of this disease. In this report, we are able to document two uncommon manifestations of leptospirosis, namely Sweet’s syndrome and central nervous system vasculitis.

    2001-01-01

    Objective. To report the magnetic resonance imaging (MRI) findings of acute cervical central cord syndrome and to determine their correlation with the prognosis. Methods. MRI findings of 35 patients with acute central cord syndrome were studied and compared with the recovery rate of ASIA score at presentation and in follow-up. Results. MRI data demonstrated spinal cord compression for 32 patients, spinal cord swelling for 16 patients, and abnormal signal intensity within the spinal cord for 19 patients, including 14 with edema and 3 with hematoma. No significant difference of the recovery rate was noted between the patients treated nonoperatively and operatively (P >0.05). There was a significant inverse correlation between the recovery rate and the degree of spinal cord compression as shown in MRI scans (P<0.01). The presence of hematoma in MRI scans was associated with poor prognosis, as demonstrated by a significant difference of the recovery rate (P< 0.01) among the patients with normal intensity, edema and hematoma within the spinal cord. Conclusions. MRI scans provide an efficient assistance for decision-making and accurate prognostic information regarding neurological function, and therefore should routinely be performed within the early phase of acute central cord syndrome.

  10. Editorial review: an update on central sensitivity syndromes and the issues of nosology and psychobiology.

    Central sensitization (CS), simply defined as an amplified response of the central nervous system to peripheral input, is a concept of great importance in clinical medicine. It has helped to explain aspects of the pathophysiology of common diseases, e.g. fibromyalgia syndrome (FMS), irritable bowel syndrome, vulvodynia, headaches, chronic pelvic pain and other overlapping conditions (collectively called central sensitivity syndromes, or CSS). It also applies to pain of complex regional pain syndrome, osteoarthritis (OA), rheumatoid arthritis (RA) and post-operative pain. The pathology-pain gap in CSS is readily explained by CS. Many FMS and other CSS patients have peripheral pathology, e.g. nociceptive areas in the muscles, arthritis, small fiber neuropathy and inflammation. Pro-inflammatory cytokines are elevated in some patients. Identification of CS in patients with structural pathology, e.g. OA and RA, has helped to explain why not all patients benefit from nonsteroidal anti-inflammatory drugs or joint replacement surgery, and require therapy directed at CS. Glial cells are important in pain processing. Remarkable advances have been achieved in neuroimaging, including visualization of grey matter and white matter, not only during provoked pain but also pain at rest. Based on CS mechanisms, targeted individual therapy may now be possible. Appropriate nosology is important particularly for effective patient care. Dichotomy of neurochemical-structural ("functional") and structural ("organic") pathology should be abandoned; many patients have both. Psychobiology is also biology. Patient-blaming terms like somatization, somatizer and catastrophizing should be avoided. For therapy, both pharmacological and non- pharmacological approaches are important, including recognition of subgroups and person/patient-centered care.

    2015-12-01

    Full Text Available Objective: Ocular ischemic syndrome is a rare blinding condition generally caused by disease of the carotid artery. We describe a 69-year-old female with a 50 pack-year smoking history with aortic arch syndrome causing bilateral ocular ischemic syndrome. Methods: The patient presented with progressive visual loss and temple pain. Slit lamp biomicroscopy revealed bilateral iris neovascularization. This finding prompted a cardiovascular work up. Panretinal photocoagulation with retrobulbar block was performed in the right eye. Results: A temporal artery biopsy was negative. The carotid duplex sound showed only a 1–39% stenosis. MRA revealed a more proximal occlusion of the aortic branch for which she underwent subclavian carotid bypass surgery. At the one month follow up, the right eye suffered profound vision loss secondary to a central retinal artery occlusion. Conclusion: Ocular neovascularization may be one of the clinical manifestations of aortic arch syndrome. This case also illustrates the limitations of relying solely on carotid duplex ultrasound testing. We caution against overly aggressive panretinal photocoagulation utilizing retrobulbar anesthesia.

    Busch, V; Frese, A; Bartsch, T

    2004-10-01

    The activation of the trigeminal nociceptive system is the neural substrate of pain in primary headache syndromes such as migraine and cluster headache. The nociceptive inflow from the meninges to the spinal cord is relayed in brainstem neurones of the trigemino-cervical complex (TCC). Two important mechanisms of pain transmission are reviewed: convergence of nociceptive trigeminal and cervical afferents and sensitization of trigemino-cervical neurones. These mechanisms have clinical correlates such as hyperalgesia, allodynia, spread and referral of pain to trigeminal or cervical dermatomes. Neurones in the TCC are subject to a modulation of pain-modulatory circuits in the brainstem such as the periaqueductal grey (PAG). Recent experimental and clinical findings of a modulation of these pain processes are discussed. The review focuses on TCC neurones as integrative relay neurones between peripheral and central pain mechanisms. The understanding of these mechanisms has implications for the understanding of the clinical phenomenology in primary headache syndromes and the development of therapeutical options.

    2016-05-01

    We describe a 2-year-old female with a suprasellar primitive neuroectodermal tumor and central diabetes insipidus (DI) who developed polyuria with natriuresis and subsequent hyponatremia 36 hr after cisplatin administration. The marked urinary losses of sodium in combination with a negative sodium balance led to the diagnosis of cisplatin-induced renal salt wasting syndrome (RSWS). The subsequent clinical management is very challenging. Four weeks later she was discharged from ICU without neurological sequela. The combination of cisplatin-induced RSWS with DI can be confusing and needs careful clinical assessment as inaccurate diagnosis and management can result in increased neurological injury.

    Sudden unexpected infant death (SUID) in infancy which includes Sudden Infant Death Syndrome (SIDS) is the commonest diagnosed cause of death in the United States for infants 1 month to 1 year of age. Central nervous system mechanisms likely contribute to many of these deaths. We discuss some of these including seizure disorders, prolonged breath holding, arousal from sleep and its habituation, laryngeal reflex apnea potentiated by upper airway infection, and failure of brainstem-mediated autoresuscitation. In the conclusions section, we speculate how lives saved through back sleeping might result in later developmental problems in certain infants who otherwise might have died while sleeping prone.

    2000-04-01

    We report a 51-year-old man with mild left central facial palsy and left Avellis' syndrome due to a small medullary infarction. On admission, neurological examination revealed hoarseness, dysphasia, absent left gag reflex, palsies of the left vocal cord and left soft palate, and hypalgesia and thermohypesthesia on the right side of the trunk and extremities. In addition, he had a mild left central facial palsy. He had no nausea, vomiting, vertigo, hiccups, nystagmus, Horner's sign, facial numbness, or paresis or ataxia of the limbs. A T2 weighted MRI showed a small, high signal intensity area in the left dorsal region of the medulla and this lesion was presumed to involve the nucleus ambiguus and a part of the spinothalamic tract. These findings suggest that an aberrant supranuclear pathway, looping around the nucleus ambiguus to the facial nucleus exists in our patient.

    Full Text Available The paper describes features history, risk factors and hospital management of acute coronary syndrome (ACS in women of the Central Asia (829 ACS patients are included, and also comparison of hospital outcomes of ACS in groups of men and women.ACS in women in the Central Asia comprises features as more non Q-wave myocardial infarction frequency, smaller adherence to treatment of dyslipidemia, more obesity degrees. Women arrive to hospital average in 4 hours after men; have more percent of the atypical form. In-hospital outcomes in men and women significantly did not differ because of general tendency to late arriving to the hospital and small quantity of revascularization procedures. The reasons of differences between men and women in the region are mostly connected to social sphere (late arriving, non-treated dyslipidemia than to physiological peculiarities.

    Objective Ehlers–Danlos syndrome frequently causes acute and chronic pain because of joint subluxations and dislocations secondary to hypermobility. Current treatments for pain related to Ehlers–Danlos syndrome and central pain syndrome are inadequate. This case report discusses the therapeutic use of ketamine intravenous infusion as an alternative. Case report A 27-year-old Caucasian female with a history of Ehlers–Danlos syndrome and spinal cord ischemic myelopathy resulting in central pain syndrome, presented with severe generalized body pain refractory to multiple pharmacological interventions. After a 7-day course of ketamine intravenous infusion under controlled generalized sedation in the intensive care unit, the patient reported a dramatic reduction in pain levels from 7–8 out of 10 to 0–3 out of 10 on a numeric rating scale and had a significant functional improvement. The patient tolerated a reduction in her pain medication regimen, which originally included opioids, gabapentin, pregabalin, tricyclic antidepressants, and nonsteroidal anti-inflammatory drugs. Conclusion Ketamine infusion treatment has been used in various pain syndromes, including central neuropathic pain, ischemic pain, and regional pain syndrome. Reports have suggested that ketamine modulates pain by the regression of N-methyl-D-aspartate receptor to a resting state. As such, propagation of nociceptive signal to brain is interrupted allowing for the restoration of physiological balance between pain inhibition and facilitation. The present report shows that this treatment option can be used in patients with refractory central pain syndrome in the setting of spinal cord myelopathy secondary to Ehlers–Danlos syndrome. In addition, as seen in this case, this protocol can potentially decrease the chronic use of pain medication, such as opioids.

    Full Text Available Abstract Background Central post-stroke pain (CPSP is a neuropathic pain syndrome associated with somatosensory abnormalities due to central nervous system lesion following a cerebrovascular insult. Post-stroke pain (PSP refers to a broader range of clinical conditions leading to pain after stroke, but not restricted to CPSP, including other types of pain such as myofascial pain syndrome (MPS, painful shoulder, lumbar and dorsal pain, complex regional pain syndrome, and spasticity-related pain. Despite its recognition as part of the general PSP diagnostic possibilities, the prevalence of MPS has never been characterized in patients with CPSP patients. We performed a cross-sectional standardized clinical and radiological evaluation of patients with definite CPSP in order to assess the presence of other non-neuropathic pain syndromes, and in particular, the role of myofascial pain syndrome in these patients. Methods CPSP patients underwent a standardized sensory and motor neurological evaluation, and were classified according to stroke mechanism, neurological deficits, presence and profile of MPS. The Visual Analogic Scale (VAS, McGill Pain Questionnaire (MPQ, and Beck Depression Scale (BDS were filled out by all participants. Results Forty CPSP patients were included. Thirty-six (90.0% had one single ischemic stroke. Pain presented during the first three months after stroke in 75.0%. Median pain intensity was 10 (5 to 10. There was no difference in pain intensity among the different lesion site groups. Neuropathic pain was continuous-ongoing in 34 (85.0% patients and intermittent in the remainder. Burning was the most common descriptor (70%. Main aggravating factors were contact to cold (62.5%. Thermo-sensory abnormalities were universal. MPS was diagnosed in 27 (67.5% patients and was more common in the supratentorial extra-thalamic group (P Conclusions The presence of MPS is not an exception after stroke and may present in association with CPSP

    Myoclonic status in nonprogressive encephalopathy (MSNE) is an early-onset, drug-resistant epileptic syndrome characterized by occurrence of continuous diffuse epileptiform abnormalities, associated with positive and/or negative phenomena and accompanied by transient and recurring motor, cognitive, and behavioral impairment. MSNE has been reported in Angelman syndrome (AS) secondary to 15q11-13 deletions or UBE3A mutations but not to paternal uniparental disomy (UPD). We describe the case of a male patient with AS caused by UPD who developed a myoclonic status (MS) associated with long-lasting fever of central origin, both promptly regressed with introduction of levetiracetam. Only three descriptions of thermal dysregulation in AS exist, and none of the previously reported cases were associated with MS or with UPD. Association of MS and central fever expands the spectrum of epileptic and non-epileptic features in UPD-related AS and provides a further evidence of hypothalamus involvement in the pathogenesis of this neurodevelopmental disorder.

However, the combination of GHD, CPP, and Klinefelter syndrome has never been reported. We described a Klinefelter syndrome patient who developed GHD at age 2 10/12 years and CPP at 8 6/12 years. Despite CPP, GnRH agonist therapy was not initiated because of his excellent predicted adult height. At 11 8/12 years, his height was 164.6 cm, close to his mid-parental target height of 165 cm. We report an additional nine patients with Klinefelter syndrome and GHD from the Pfizer International Growth Study (KIGS) database, none of whom had CPP. We conclude that the combination of GHD and CPP is very rare in Klinefelter syndrome and that CPP is unlikely to compromise final adult height.

Current treatments for pain related to Ehlers–Danlos syndrome and central pain syndrome are inadequate. This case report discusses the therapeutic use of ketamine intravenous infusion as an alternative. Case report: A 27-year-old Caucasian female with a history of Ehlers–Danlos syndrome and spinal cord ischemic myelopathy resulting in central pain syndrome, presented with severe generalized body pain refractory to multiple pharmacological interventions. After a 7-day course of ketamine intravenous infusion under controlled generalized sedation in the intensive care unit, the patient reported a dramatic reduction in pain levels from 7–8 out of 10 to 0–3 out of 10 on a numeric rating scale and had a significant functional improvement. The patient tolerated a reduction in her pain medication regimen, which originally included opioids, gabapentin, pregabalin, tricyclic antidepressants, and nonsteroidal anti-inflammatory drugs. Conclusion: Ketamine infusion treatment has been used in various pain syndromes, including central neuropathic pain, ischemic pain, and regional pain syndrome. Reports have suggested that ketamine modulates pain by the regression of N-methyl-D-aspartate receptor to a resting state. As such, propagation of nociceptive signal to brain is interrupted allowing for the restoration of

    Full Text Available ABSTRACT: AIM: To report a case of Central Retinal Artery Occlusi on (CRAO in young males in its initial manifestation as Primary Antiphospholipid Syndrome. METHODS: 32 year healthy male, with abrupt sudden painless loss of vision in r ight eye since 48 hours, with Grade 2 Relative afferent pupillary defect, visual acuity of hand movements in OD and 6/18 in OS. Fundoscopy disclosed signs compatible of central reti nal artery occlusion confirmed with FFA. Carotid Doppler imaging and echocardiography was done to determine the source. RESULTS: Antiphospholipid antibody cofactor, beta2-glycoprotein 1 antibodies, IgM, was positive with titre of more than 94 un its/ml on two occasions, 1 2 weeks apart, with normal range being less than 20 units/ml for each isotope (IgG, IgM, or IgA .According to the 2006 revised Sapporo criteria Antiphospholipid syndrome was diagnosed. Thor ough examination excluded other system involvement. Immunological studies excluded other systemic disorders. CONCLUSIONS: In literature, prevalence of CRAO is 0.85% for every 100000 and prevalence of Antiphospholipid Syndrome in patients showing a major retinal vascula r obstruction is 5% - 33%. Antiphospholipid syndrome should be ruled out in every young patient who presents with Central retinal artery occlusion. Association must be considered, as Central retinal artery occlusion could be the initial manifestation of ant iphospholipid syndrome with high risk of recurrence.

    Full Text Available Abstract The trisomy 18 syndrome, also known as Edwards syndrome, is a common chromosomal disorder due to the presence of an extra chromosome 18, either full, mosaic trisomy, or partial trisomy 18q. The condition is the second most common autosomal trisomy syndrome after trisomy 21. The live born prevalence is estimated as 1/6,000-1/8,000, but the overall prevalence is higher (1/2500-1/2600 due to the high frequency of fetal loss and pregnancy termination after prenatal diagnosis. The prevalence of trisomy 18 rises with the increasing maternal age. The recurrence risk for a family with a child with full trisomy 18 is about 1%. Currently most cases of trisomy 18 are prenatally diagnosed, based on screening by maternal age, maternal serum marker screening, or detection of sonographic abnormalities (e.g., increased nuchal translucency thickness, growth retardation, choroid plexus cyst, overlapping of fingers, and congenital heart defects . The recognizable syndrome pattern consists of major and minor anomalies, prenatal and postnatal growth deficiency, an increased risk of neonatal and infant mortality, and marked psychomotor and cognitive disability. Typical minor anomalies include characteristic craniofacial features, clenched fist with overriding fingers, small fingernails, underdeveloped thumbs, and short sternum. The presence of major malformations is common, and the most frequent are heart and kidney anomalies. Feeding problems occur consistently and may require enteral nutrition. Despite the well known infant mortality, approximately 50% of babies with trisomy 18 live longer than 1 week and about 5-10% of children beyond the first year. The major causes of death include central apnea, cardiac failure due to cardiac malformations, respiratory insufficiency due to hypoventilation, aspiration, or upper airway obstruction and, likely, the combination of these and other factors (including decisions regarding aggressive care.

    Obesity is an established risk factor for esophageal adenocarcinoma, although the mechanism is unclear. A pathway from reflux to inflammation through metaplasia is the dominant hypothesis, and an added role relating to visceral adiposity and the metabolic syndrome has been mooted in Barrett\\'s esophagus (BE) patients. Whether BE differs from gastroesophageal reflux disease (GERD) in obesity and metabolic syndrome profiles is unclear, and this was the focus of this study. Patients with proven BE or GERD were randomly selected from the unit data registry and invited to attend for metabolic syndrome screening, anthropometry studies including segmental body composition analysis, and laboratory tests including fasting lipids, insulin, and C-reactive protein. Metabolic syndrome was defined using the National Cholesterol Education Program (NCEP) and the International Diabetes Federation (IDF) criteria. One hundred and eighteen BE patients and 113 age- and sex-matched GERD controls were studied. The incidence of obesity (body mass index >30 kg\\/m(2)) was 36% and 38%, respectively, with the pattern of fat deposition predominantly central and an estimated trunk fat mass of 13 and 14 kg, respectively. Using the NCEP criteria, metabolic syndrome was significantly more common in the BE cohort (30% vs 20%, P < 0.05), but there was no significant difference using IDF criteria (42% vs 37%, P= 0.340). Central obesity and the metabolic syndrome are common in both Barrett\\'s and GERD cohorts, but not significantly different, suggesting that central obesity and the metabolic syndrome does not per se impact on the development of BE in a reflux population. In BE, the importance of obesity and the metabolic syndrome in disease progression merits further study.

    Fibulin-1 is an extracellular matrix protein that has an important role in the structure of elastic fibers and basement membranes of various tissues. Using homozygosity mapping and exome sequencing, we discovered a missense mutation, p.(Cys397Phe), in fibulin-1 in three patients from a consanguineous family presented with a novel syndrome of syndactyly, undescended testes, delayed motor milestones, mental retardation and signs of brain atrophy. The mutation discovered segregated with the phenotype and was not found in 374 population-matched alleles. The affected cysteine is highly conserved across vertebrates and its mutation is predicted to abolish a disulfide bond that defines the tertiary structure of fibulin-1. Our findings emphasize the crucial role fibulin-1 has in development of the central nervous system and various connective tissues.

    Central pontine myelinolysis (CPM), which was originally considered to be the result of rapid correction of chronic hyponatremia, is not necessarily accompanied by hyponatremia or drastic changes in serum sodium level. Here, we report a case of an anorexic 55-year-old male with a history of pharyngo-laryngo-esophagogastrectomy, initially hospitalized with status epilepticus. Although his consciousness gradually recovered as we were controlling his convulsion, it deteriorated again with new onset of anisocoria, and magnetic resonance imaging (MRI) at this point revealed CPM. Rapid change of serum sodium or osmolarity, which is often associated with CPM, had not been apparent throughout his hospitalization. Instead, a review of the serum biochemistry test results showed that serum phosphate had drastically declined the day before the MRI first detected CPM. In this case, we suspect that hypophosphatemia induced by refeeding syndrome greatly contributed to the occurrence of CPM.

    Turner syndrome (TS) is a genetic disorder that affects development in females and is characterized by the complete or partial absence of the second sex chromosome, or monosomy X. TS is associated with abnormalities in lymphatic and skeletal development, in growth, and in gonadal function. Cardiac and renal malformations and a number of specific cognitive findings may also be encountered in these patients. An increased risk for hypothyroidism, sensorineural hearing loss, hypertension, and other problems has also been reported. We present the case of a patient with TS accompanied by transient hypogammaglobulinaemia of infancy (THI) and central diabetes insipidus, which we believe is the first reported TS patient with these concomitant disorders.

    Haglund syndrome is characterized by chronic posterior heel pain associated with a posterosuperior calcaneal prominence. We assessed the clinical and radiologic outcomes after operative treatment of Haglund syndrome using the central tendon-splitting approach. Fifteen feet in 15 patients were investigated retrospectively after surgery. Of the 15 patients, 14 were males (93.3%) and 1 was female (6.7%). Their mean age was 33.1 ± 8.2 (range 20 to 50) years. The mean follow-up duration was 3.5 ± 1.5 years (range 24 to 90 months). The American Orthopaedic Foot and Ankle Society ankle-hindfoot Scale and Victorian Institute of Sport Assessment-Achilles scores were investigated to assess the clinical outcomes. Patient satisfaction was assessed at the latest follow-up visit. The lateral talo-first metatarsal angle, calcaneal pitch angle, Fowler-Philip angle, and parallel pitch line were measured to assess the foot shape and radiographic outcomes. Clinically, the mean American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score increased from 62.1 ± 7.5 preoperatively to 92.5 ± 3.5 at the latest follow-up visit. The mean Victorian Institute of Sport Assessment-Achilles score increased from 53.2 ± 7.4 to 89.6 ± 3.4. All patients were satisfied with the operative results. Radiographically, all patients had cavus feet with an increased lateral talo-first metatarsal angle (mean +5.9° ± 5.0°) and calcaneal pitch angle (mean 26.0° ± 3.8°). The mean Fowler-Philip angle decreased from 58.9° ± 15.0° to 32.5° ± 7.2° postoperatively, and the positive parallel pitch line had changed to a negative value in all cases. Operative treatment with the central tendon-splitting approach appears to be safe and satisfactory for intractable Haglund syndrome.

    Perry syndrome consists of early-onset parkinsonism, depression, severe weight loss and hypoventilation, in which brain pathology is characterized by TDP-43 immunostaining. Through genome-wide linkage analysis we have identified five disease-segregating dynactin (DCTN1) CAP-Gly domain substitutions in 8 families that diminish microtubule binding and lead to intracytoplasmic inclusions. DCTN1 mutations were previously associated with motor neuron disease but can underlie the selective vulnerab...

    Full Text Available OBJECTIVES: Sjögren syndrome is an autoimmune disease involving mainly salivary and lacrimal glands. Beyond widely described PNS involvement, high variable prevalence of CNS manifestations ranging from 2.5 and 60% of all pSS patients has been reported, without specific syndrome definition. The aim of this cohort study was to evaluate the prevalence of CNS signs and symptoms in pSS patients and to identify possible biomarkers of CNS damage. METHODS: 120 patients with pSS diagnosis according to the 2002 American-European Consensus Group criteria were enrolled after exclusion of secondary causes. All patients underwent to a wide neurological, neuropsychological, psychiatric, neuroradiological and ultrasonographic evaluation. RESULTS: Central and peripheral nervous system involvement was observed in 81 patients with a prevalence of 67.5%. The prevalence of CNS involvement was significantly higher than PNS disease (p 0.001. 68 patients (84% shown non-focal CNS symptoms and 64 (79% focal CNS deficits with headache as the most common feature (46.9%, followed by cognitive (44.4% and mood disorders (38.3%. Particularly, we observed a high prevalence of migraine without aura, subcortical frontal executive functions and verbal memory impairment and apathy/alexythimia. MR spectroscopy revealed a reduction of NAA levels or NAA/Cr ratio decrease in subcortical frontal and basal ganglia white matter, while ultrasonography showed an impairment of microvasculature response. At multivariate analysis, headache, cognitive disorders and psychiatric symptoms was significantly associated to serological markers (anti-SSA, MRS and ultrasonographic features. CONCLUSIONS: The higher prevalence of MWO-mimic headache, cognitive dys-executive syndrome and mood disorders observed in this series confirmed previous evidences of a higher diffused CNS compromission rather than focal involvement such as SM-like clinical course or NMO-like syndrome.

    Full Text Available Purpose: To describe a case of bilateral and simultaneous central retinal vein occlusion (RVO in a young patient diagnosed with obstructive sleep apnea syndrome (OSAS. Case Report: A 38-year-old man with morbid obesity and daytime sleepiness presented with a history of bilateral vision loss. His visual acuity (VA was hand movements, and fundus examination (FE revealed bilateral central RVO. General medical examination revealed untreated hypertension and type II respiratory failure. Laboratory tests for thrombophilia showed increased hematocrit (59% and high levels of fibrinogen and C-reactive protein. Other causes of congenital and acquired hypercoagulability were ruled out. Pathologic polysomnography led to the diagnosis of OSAS. The patient was treated with antihypertensive drugs and continuous positive air pressure. In addition, he received intravitreal ranibizumab. At 10 months after presentation, his VA was no light perception in the right eye and hand movements in the left eye. FE revealed bilateral retinal and optic nerve atrophy, and the occurrence of a nonarteritic anterior ischemic neuropathy in the right eye was considered.

    We report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues. oodpasture's syndrome is a rare disease, characterized by rapidly progressive glomerulonephritis, diffuse pulmonary hemorrhage and circulating antiglomerular basement membrane antibody (anti-GBM antibody). Central nervous system (CNS) manifestations in Goodpasture's syndrome are extremely rare, with only a few cases having been reported in the literature (8 10). Therefore, we present our imaging findings of CNS vasculitis associated with Goodpasture's syndrome, together with a review of the relevant literature. In summary, CNS vasculitis associated with Goodpasture's syndrome is extremely rare. Awareness of the imaging findings, as well as the clinical significance of CNS vasculitis associated with Goodpasture's syndrome, can be helpful in making the correct diagnosis and subsequent management of this rare condition.

Evaluation of central corneal thickness (CCT and endothelial cell density (ECD in patients with senile cataract and coexisting pseudoexfoliation (PEX syndrome with glaucoma (PEXG and without glaucoma using specular microscopy. Participants and Methods. The study included 122 patients (217 eyes. In this group of patients we identified 133 eyes with PEX syndrome (65 with glaucoma, 68 without glaucoma and 84 eyes without PEX syndrome. ECD and CCT were measured in each eye by specular microscopy. Results. ECD in eyes with PEX syndrome without glaucoma (2297 ± 359 cell/mm2 and in eyes with PEXG (2241 ± 363 cell/mm2 was lower than in the control group (2503 ± 262 cell/mm2 (P<0.001. CCT in eyes with PEXG (508.2 ± 32.6 μm was thinner than in eyes with PEX syndrome without glaucoma (529.7 ± 30.3 μm and control group (527.7 ± 29.4 μm (P<0.001. Conclusions. This research shows that in eyes with PEX syndrome, both with and without glaucoma, ECD was statistically significantly lower than in the control group. In patients with PEXG, CCT was statistically significantly thinner than in the PEX syndrome and control group.

    Full Text Available OBJECTIVE: Subjects with Polycystic ovarian syndrome (PCOS are at increased risk of Type 2 diabetes mellitus (T2DM. The mechanism of this enhanced risk is unclear. Circulating vascular progenitor cells (VPC are immature bone marrow derived cells capable of differentiating into mature endothelial cells. VPC number/function and central arterial stiffness predict cardio-metabolic disease in at-risk populations. DESIGN: We studied VPC and arterial stiffness measures in non-obese PCOS subjects as compared to age and body mass index (BMI matched healthy controls in a cross-sectional study. METHODS: Fourteen subjects with PCOS and 12 controls of similar age, BMI (all <30 kg/m(2 and metabolic profile were studied. VPC number and in vitro function were studied by flow cytometry and tube formation assays respectively. Augmentation index (AIx, a measure of central arterial stiffness, and central (aortic blood pressures (BP were measured by applanation tonometry. RESULTS: Subjects with PCOS had a reduced number, mean±SEM, of circulating CD34(+133(+ VPCs (317.5±51.0 vs. 558.3±101.2, p = 0.03 and impaired in vitro tube formation (completed tube area 1.0±0.06 vs. 1.2±0.05×10(6 µm(2 p = 0.02. PCOS subjects had significantly higher AIx (18.4±1.9% vs. 4.9±2.0% and this difference remained significant even after adjustments for age, BMI and smoking (p = 0.003 in multivariate analyses. Central systolic and pulse pressure were higher in PCOS subjects but these differences were not statistically significant after adjustment for age. Brachial systolic and pulse pressures were similar. VPC number/function and arterial stiffness or BP measures were not correlated. CONCLUSIONS: Non-obese PCOS is characterized by a reduced VPC number, impaired VPC function and increased central arterial stiffness. These changes in novel vascular risk markers may explain the enhanced risk of T2DM and CVD in PCOS.

    Clinical manifestations typical of mitochondrial diseases are often present in various genetic syndromes associated with intellectual disability, a condition leading to deficit in cognitive functions and adaptive behaviors. Until now, the causative mechanism leading to intellectual disability is unknown and the progression of the condition is poorly understood. We first report latest advances on genetic and environmental regulation of mitochondrial function and its role in brain development. Starting from the structure, function and regulation of the oxidative phosphorylation apparatus, we review how mitochondrial biogenesis and dynamics play a central role in neurogenesis and neuroplasticity. We then discuss how dysfunctional mitochondria and alterations in reactive oxygen species homeostasis are potentially involved in the pathogenesis of various neurodevelopmental syndromes with a special focus on Down, Rett, Fragile X syndromes and autism spectrum disorders. Finally, we review and suggest novel therapeutic approaches aimed at improving intellectual disability by activating mitochondrial function and reducing oxidative stress to amiliorate the quality of life in the subjects affected.

    The authors of this paper wish to present a case of fatal cor pulmonale with right ventricular hypertrophy complicated by a congenital myopathy. It is our intention to demonstrate the importance of vigilant clinical assessment of children with a congenital myopathy, regardless of the exact etiology of their disease, or family history of disease severity. This case highlights the risk for fatal complications if hypoventilation and respiratory insufficiency go unrecognized in myopathic children. Consequently, we recommend respiratory and cardiac monitoring surveillance as well as appropriate referral to specialists in the management of such children.

    Full Text Available Abstract Background Cancer treatment with a variety of chemotherapeutic agents often is associated with delayed adverse neurological consequences. Despite their clinical importance, almost nothing is known about the basis for such effects. It is not even known whether the occurrence of delayed adverse effects requires exposure to multiple chemotherapeutic agents, the presence of both chemotherapeutic agents and the body's own response to cancer, prolonged damage to the blood-brain barrier, inflammation or other such changes. Nor are there any animal models that could enable the study of this important problem. Results We found that clinically relevant concentrations of 5-fluorouracil (5-FU; a widely used chemotherapeutic agent were toxic for both central nervous system (CNS progenitor cells and non-dividing oligodendrocytes in vitro and in vivo. Short-term systemic administration of 5-FU caused both acute CNS damage and a syndrome of progressively worsening delayed damage to myelinated tracts of the CNS associated with altered transcriptional regulation in oligodendrocytes and extensive myelin pathology. Functional analysis also provided the first demonstration of delayed effects of chemotherapy on the latency of impulse conduction in the auditory system, offering the possibility of non-invasive analysis of myelin damage associated with cancer treatment. Conclusions Our studies demonstrate that systemic treatment with a single chemotherapeutic agent, 5-FU, is sufficient to cause a syndrome of delayed CNS damage and provide the first animal model of delayed damage to white-matter tracts of individuals treated with systemic chemotherapy. Unlike that caused by local irradiation, the degeneration caused by 5-FU treatment did not correlate with either chronic inflammation or extensive vascular damage and appears to represent a new class of delayed degenerative damage in the CNS.

Clinical features include neonatal hypotonia, poor weight gain in early infancy followed by binge eating from childhood to adulthood, severe obesity, developmental delay, short stature, and hypogonadism of both central and peripheral etiology. Central hypothyroidism and adrenal insufficiency may occur. Sleep disordered breathing, by obstruction of upper airways associated with central hypoventilation, is a common feature. Most of these characteristics are assumed to be the result of a hypothalamic dysfunction. The most important complication and the most difficult to manage is the obesity. This review aims at discussing the most recent strategies to manage the endocrine complications of Prader–Willi syndrome patients, with a special approach on the treatment of obesity, hypogonadism, and short stature. We summarize the indication and effects of recombinant human growth hormone therapy on growth, cognitive development, and body composition, and discuss the effects of recombinant human growth hormone therapy on the resulting sleep disorders.Keywords: Prader–Willi syndrome, obesity, hypogonadism, growth hormone, sleep disorder

    Full Text Available Clinical and imaging data of 4 cases of primary Sjögren's syndrome (pSS combined with central nervous system (CNS lesions were retrospectively analyzed. Clinical symptoms of 4 patients were as follows: 2 cases had fever; 2 cases had blurred vision; 2 cases had lower extremity weakness; one case had single lower limb weakness; one case had unilateral limb weakness; one case had hemisensory reduction; one case had bilateral abducens paralysis; 3 cases had peripheral neuropathy. Analysis of cerebrospinal fluid (CSF revealed increased CSF pressure (210-270 mm H2O in 3 cases, increased number of leukocyte [(50-380 × 10 6/L] in 3 cases, and increased protein (1.30-2.56 g/L in 3 cases. Brain MRI showed multiple lesions in white matters. After high-dose steroid therapy, 3 cases had good prognosis, and one had recurrent lower extremity weakness after 6 months. pSS combined with CNS lesions is rare. Lumbar puncture and brain MRI is important for diagnosis, and high-dose steroid therapy may have good therapeutic effect. DOI: 10.3969/j.issn.1672-6731.2015.04.014

    In order to study whether Alzheimer-like neuropathological changes involve the central histaminergic system we measured the concentration of histamine, its precursor histidine as well as the activity of histidine decarboxylase (HDC) and histamine-N-methyl-transferase (HMT) in frontal cortex of aging Down syndrome (DS) patients, Alzheimer patients and control individuals. The study populations were also investigated for choline acetyltransferase (ChAT) activity, since reduced ChAT activity is an established biochemical hallmark in DS and Alzheimer disease (AD). HDC and ChAT activity were reduced in brains of both DS and Alzheimer patients versus control patients. Additionally, we observed a significant decrease of histamine levels in the DS group. Histamine levels in AD brains tended to be decreased. Histidine concentrations and HMT activities were comparable between the three groups. Thus, our results for the first time show histaminergic deficits in brains of patients with DS resembling the neurochemical pattern in AD. Neuropathological changes may be responsible for similar neurochemical alterations of the histaminergic system in both dementing disorders.

    This study was aimed to explore the anterior cervical surgery methods to treat central cord syndrome without radiographic spinal fracture-dislocation (CCSWORFD), retrospectively analyze the cases of CCSWORFD, and evaluate the curative effect of anterior cervical surgery methods for CCSWORFD. Twenty four cases of CCSWORFD (19 males and 5 females), all suffering from cervical hyperextension injury, between 45-68 (average 59) years old, were operated on by anterior cervical surgery methods. Among these, 18 cases had been followed up for 6-24 (average 15) months; 18 cases, who had anterior decompression and plate fixation with titanium mesh bone grafting or iliac bone grafting achieved reliable effects based on the Japanese Orthopedics Association (JOA) evaluation (improved scores of cases with titanium mesh bone grafting, t = 2.800, P0.05). Most of these cases had degeneration of cervical vertebra. The decompression which relieves the oppression to the spinal cord can help lessen edema of the spinal cord, and early fixation for stability of cervical vertebra is better for the recovery of spinal cord injury. Anterior operation with titanium mesh bone grafting or iliac bone grafting are both reliable curative methods for CCSWORFD, and titanium mesh bone grafting can avoid the trauma of the supplying graft. Mesh bone grafting can also shorten hospital stay.

    Full Text Available Abstract Background Central cord syndrome (CCS is considered the most common incomplete spinal cord injury (SCI. Independent ambulation was achieved in 87-97% in young patients with CCS but no gait analysis studies have been reported before in such pathology. The aim of this study was to analyze the gait characteristics of subjects with CCS and to compare the findings with a healthy age, sex and anthropomorphically matched control group (CG, walking both at a self-selected speed and at the same speed. Methods Twelve CCS patients and a CG of twenty subjects were analyzed. Kinematic data were obtained using a three-dimensional motion analysis system with two scanner units. The CG were asked to walk at two different speeds, at a self-selected speed and at a slower one, similar to the mean gait speed previously registered in the CCS patient group. Temporal, spatial variables and kinematic variables (maximum and minimum lower limb joint angles throughout the gait cycle in each plane, along with the gait cycle instants of occurrence and the joint range of motion - ROM were compared between the two groups walking at similar speeds. Results The kinematic parameters were compared when both groups walked at a similar speed, given that there was a significant difference in the self-selected speeds (p Conclusions The gait pattern of CCS patients showed a decrease of knee and ankle sagittal ROM during level walking and an increase in hip abduction to increase base of support. The findings of this study help to improve the understanding how CCS affects gait changes in the lower limbs.

    Reversible cerebral vasoconstriction syndrome (RCVS) is Raynaud's phenomenon of the brain. Changes in neurological function are dependent upon which areas of the brain are deprived of normal blood flow. Antiphospholipid antibody syndrome (APLA) is a common cause of Raynaud's phenomenon that can occur anywhere in the body, including the brain. Management of CNS vasospasm generally involves the use of centrally acting calcium channel blockers, which have been shown to relieve the associated headaches and transient neurological symptoms associated with it. Three patients with APLA and RCVS from our clinics are illustrated. It is demonstrated that the use of centrally acting calcium channel-blocking drugs, such as nimodipine, which prevent and reverse CNS vasospasm, led to clinical improvement in our patients over the course of 5-9 years. All of them had MRIs done at the initiation of therapy and 5-9 years after being on therapy. MRI measures of T2 lesion volumes (LVs) and number were obtained. All three patients had a good response in controlling clinical symptoms related to CNS vasospasm, Raynaud's phenomenon, visual disturbances, confusion, headaches, and hearing loss. There was also a resolution in the MRI findings of these patients. This case series of three patients shows a clinical improvement and decrease in T2 LV and number in patients with APLA and Raynaud's syndrome on centrally acting calcium channel blockers. RCVS is much more common than that currently appreciated. APLA is the common cause of RCVS. Further studies are needed to determine the optimal methods to diagnose RCVS and optimal therapies to treat it.

    Full Text Available We report the case of a 24-year-old man presenting with sudden visual loss in the left eye from a central retinal artery occlusion. An extensive clinical investigation revealed no etiology. Three weeks later, however, the patient developed hearing loss followed by encephalopathy and multiple branch retinal artery occlusions in the right eye. Fluorescein angiography confirmed retinal vascular occlusions with no sign of vasculitis. The neurological examination revealed a diffuse encephalopathy while the MRI scan disclosed several small areas of infarcts in the brain. Bilateral sensorineural hearing loss was confirmed on audiometry. The patient was diagnosed with Susac syndrome and treated with methylprednisolone and cyclophosphamide, resulting in slight improvement and stabilization. This case shows that Susac syndrome may be diagnosed late due to the absence at onset of one or more of the symptoms of the classic triad (encephalopathy, multiple branch retinal artery occlusions and hearing loss. This case also serves to emphasize that Susac syndrome should be considered in the differential diagnosis of central retinal artery occlusion, even in apparently healthy young men.

    Full Text Available The main selective forces affecting the fruiting strategies are related to the environment in which plants occur. As a savanna, microclimatic conditions should not vary in relation to distance from edge in cerrado sensu stricto fragments. Thus, we postulated that the importance of different dispersal syndromes would not vary towards the fragment core. Our aim was to test in four cerrado sensu stricto fragments in central Brazil whether the absolute density of anemo-, auto-, and zoochorous individuals varied in relation to edge distance. According to results, the absolute density of anemo-and autochorous individuals did not vary, whereas those of zoochorous individuals increased with edge distance, pointing out that there were other factors rather than abiotic conditions shifting zoochorous species to the interior of cerrado sensu stricto fragments.As principais forças seletivas que afetam as estratégias de frutificação estão relacionadas ao ambiente em que as plantas ocorrem. Como fragmentos de cerrado sensu stricto são savânicos, as condições microclimáticas não devem variar em relação à distância da borda. Assim, postulamos que a importância das diferentes síndromes de dispersão não varia da borda ao interior de um fragmento de vegetação. O objetivo deste trabalho foi testar, em quatro fragmentos de cerrado sensu stricto (centro-oeste do Brasil, se a densidade absoluta de indivíduos anemo, auto e zoocóricos variava em função da distância da borda. Segundo nossos resultados, a densidade absoluta de indivíduos anemo e autocóricos não variou significativamente borda em direção ao interior dos fragmentos, enquanto que a dos indivíduos zoocóricos aumentou, indicando que existem outros fatores, que não as condições abióticas, deslocando as espécies zoocóricas para o interior dos fragmentos de cerrado sensu stricto.

    Bernal, Antonio; Mahía, Javier; Puerto, Amadeo

    2016-07-01

    The aim of this study was to review different animal models of Central Diabetes Insipidus, a neurobiological syndrome characterized by the excretion of copious amounts of diluted urine (polyuria), a consequent water intake (polydipsia), and a rise in the serum sodium concentration (hypernatremia). In rodents, Central Diabetes Insipidus can be caused by genetic disorders (Brattleboro rats) but also by various traumatic/surgical interventions, including neurohypophysectomy, pituitary stalk compression, hypophysectomy, and median eminence lesions. Regardless of its etiology, Central Diabetes Insipidus affects the neuroendocrine system that secretes arginine vasopressin, a neurohormone responsible for antidiuretic functions that acts trough the renal system. However, most Central Diabetes Insipidus models also show disorders in other neurobiological systems, specifically in the secretion of oxytocin, a neurohormone involved in body sodium excretion. Although the hydromineral behaviors shown by the different Central Diabetes Insipidus models have usually been considered as very similar, the present review highlights relevant differences with respect to these behaviors as a function of the individual neurobiological systems affected. Increased understanding of the relationship between the neuroendocrine systems involved and the associated hydromineral behaviors may allow appropriate action to be taken to correct these behavioral neuroendocrine deficits.

    2016-02-01

    This case presents a clinical course of a frontal lobe dysexecutive syndrome with dementia caused by a primary angiitis of the central nervous system (PACNS) of exclusively very small vessels. An isolated frontal lobe dementia syndrome as a primary manifestation of PACNS highlights the diverse clinical manifestations of the disease. The patient presented with a progressive cognitive decline with loss of memory, disinhibited behavior, inappropriate affect and frontal release signs. The diagnostic workup essentially revealed a lymphocytic pleocytosis in the cerebrospinal fluid and a generalized cortical atrophy without any vascular abnormalities. To grasp a diagnosis for this enigmatic clinical picture of a frontal lobe syndrome with signs of inflammation we targeted a tissue-based diagnosis. A brain biopsy gave the decisive hint towards a microvasculitis. Although the histopathologic picture showed peculiarities, a destruction of the vascular bed of very small vessels by lymphocytic infiltration was evident. Our case illustrates an uncommon clinical picture of a PACNS and points to shortcomings of the current histopathologic criteria if only very small vessels are involved.

    Evidence from epidemiologic studies that central obesity precedes future metabolic change and does not occur concurrently with the appearance of the blood pressure, glucose, and lipid abnormalities that characterize the metabolic syndrome (MetS) has been lacking. Longitudinal surveys were conducted in Mauritius in 1987, 1992, and 1998, and in Australia in 2000 and 2005 (AusDiab). This analysis included men and women (aged > or = 25 years) in three cohorts: AusDiab 2000-2005 (n = 5,039), Mauritius 1987-1992 (n = 2,849), and Mauritius 1987-1998 (n = 1,999). MetS components included waist circumference, systolic blood pressure, fasting and 2-h postload plasma glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, and homeostasis model assessment of insulin sensitivity (HOMA-S) (representing insulin sensitivity). Linear regression was used to determine which baseline components predicted deterioration in other MetS components over 5 years in AusDiab and 5 and 11 years in Mauritius, adjusted for age, sex, and ethnic group. Baseline waist circumference predicted deterioration (P Mauritius 1987-1992, and four of six in Mauritius 1987-1998. In contrast, an increase in waist circumference between baseline and follow-up was only predicted by insulin sensitivity (HOMA-S) at baseline, and only in one of the three cohorts. These results suggest that central obesity plays a central role in the development of the MetS and appears to precede the appearance of the other MetS components.

  15. Central Sensitization Syndrome and the Initial Evaluation of a Patient with Fibromyalgia: A Review

    2015-04-01

    Full Text Available In both primary care and consultative practices, patients presenting with fibromyalgia (FM often have other medically unexplained somatic symptoms and are ultimately diagnosed as having central sensitization (CS. Central sensitization encompasses many disorders where the central nervous system amplifies sensory input across many organ systems and results in myriad symptoms. A pragmatic approach to evaluate FM and related symptoms, including a focused review of medical records, interviewing techniques, and observations, is offered here, giving valuable tools for identifying and addressing the most relevant symptoms. At the time of the clinical evaluation, early consideration of CS may improve the efficiency of the visit, reduce excessive testing, and help in discerning between typical and atypical cases so as to avoid an inaccurate diagnosis. Discussion of pain and neurophysiology and sensitization often proves helpful.

    Numerous autoimmune diseases can affect the central nervous system (CNS), and variable clinical presentations confound the differential diagnosis. The challenging task of properly characterizing various CNS autoimmune diseases enables patients to be rapidly triaged and appropriately treated. In this review article, we aim to explore different CNS manifestations of rheumatologic diseases with emphasis on the utility of imaging and cerebrospinal fluid findings. We review the classic physical examination findings, characteristic imaging features, cerebrospinal fluid results, and serum biomarkers. In addition, we also present a unique case of newly described autoimmune entity CLIPPERS syndrome. Our case is unique in that this is the first case which demonstrates involvement of the supratentorial perivascular spaces in addition to the classic infratentorial involvement as initially described by Pittock et al (Brain. 2010;133:2626-2634).

  17. Association of CHRDL1 mutations and variants with X-linked megalocornea, Neuhauser syndrome and central corneal thickness.

    Full Text Available We describe novel CHRDL1 mutations in ten families with X-linked megalocornea (MGC1. Our mutation-positive cohort enabled us to establish ultrasonography as a reliable clinical diagnostic tool to distinguish between MGC1 and primary congenital glaucoma (PCG. Megalocornea is also a feature of Neuhäuser or megalocornea-mental retardation (MMR syndrome, a rare condition of unknown etiology. In a male patient diagnosed with MMR, we performed targeted and whole exome sequencing (WES and identified a novel missense mutation in CHRDL1 that accounts for his MGC1 phenotype but not his non-ocular features. This finding suggests that MMR syndrome, in some cases, may be di- or multigenic. MGC1 patients have reduced central corneal thickness (CCT; however no X-linked loci have been associated with CCT, possibly because the majority of genome-wide association studies (GWAS overlook the X-chromosome. We therefore explored whether variants on the X-chromosome are associated with CCT. We found rs149956316, in intron 6 of CHRDL1, to be the most significantly associated single nucleotide polymorphism (SNP (p = 6.81×10(-6 on the X-chromosome. However, this association was not replicated in a smaller subset of whole genome sequenced samples. This study highlights the importance of including X-chromosome SNP data in GWAS to identify potential loci associated with quantitative traits or disease risk.

    Full Text Available Background and Objectives: Metabolic syndrome - a plausible precondition for type II diabetes and cardiovascular diseases is also on rise. To understand the mechanistic complexity of metabolic syndrome it is imperative to study the specific contribution of the determinants of metabolic syndrome. Such study can help to identify the most significant factor which may be of use in early detection as well as prevention efforts. Such information is scarcely available from India and especially from rural India. Hence, the present study was undertaken to explore for such factor which might be considered crucial for development of such pathogenesis particularly in rural population of Wardha. Methods: A cross-sectional study comprising of 300 subjects was carried out in rural area of Primary Health Center, attached to medical college with approximate 31,000 populations. The anthropometric parameters such as height, weight, waist circumference were measured. Overnight fasting samples were collected for lipid profile (total cholesterol, triglyceride, high density lipoproteins, low density lipoproteins, very low density lipoproteins and fasting blood glucose levels. The National Cholesterol Education Programme Adult Treatment Panel, ATP-III guidelines were used to categorize the study subjects. As many of the variables are highly intercorrelated, exploratory factor analysis was carried out to reduce the data to a smaller number of independent factors that accounts for the most of the variances in the data. Principal component analysis was used as a method of extraction. Results: For both sexes, three factors were extracted accounting for about 71% variance in the measured variables. An adiposity factor which accounted for highest explained variance (28%, was the initial factor extracted. It was loaded positively by waist circumference, triglyceride, and very low density lipoprotein and negatively loaded by high density lipoprotein. Second factor extracted

    2005-05-01

    Patients with silent sinus syndrome typically present for investigation of facial asymmetry. Unilateral, spontaneous enophthalmos and hypoglobus are the prominent findings at examination. Imaging of the orbit and sinuses characteristically show unilateral maxillary sinus opacification and collapse with inferior bowing of the orbital floor. It has been suggested that SSS is due to hypoventilation of the maxillary sinus secondary to ostial obstruction and sinus atelectasis with chronic negative pressure within the sinus. Treatment involves functional endoscopic sinus surgery for reestablishing a functional drainage passage, and a reconstructive procedure of the floor of the orbit for repairing the hypoglobus and cosmetic deformity. Ophthalmologists, otorhinolaryngologists, and radiologists must be familiarized with this relatively newly reported disease.

    Work, Thierry M.; Aeby, Greta S.

    2011-01-01

    We performed histological examination of 69 samples of Acropora sp. manifesting different types of tissue loss (Acropora White Syndrome-AWS) from Hawaii, Johnston Atoll and American Samoa between 2002 and 2006. Gross lesions of tissue loss were observed and classified as diffuse acute, diffuse subacute, and focal to multifocal acute to subacute. Corals with acute tissue loss manifested microscopic evidence of necrosis sometimes associated with ciliates, helminths, fungi, algae, sponges, or cyanobacteria whereas those with subacute tissue loss manifested mainly wound repair. Gross lesions of AWS have multiple different changes at the microscopic level some of which involve various microorganisms and metazoa. Elucidating this disease will require, among other things, monitoring lesions over time to determine the pathogenesis of AWS and the potential role of tissue-associated microorganisms in the genesis of tissue loss. Attempts to experimentally induce AWS should include microscopic examination of tissues to ensure that potentially causative microorganisms associated with gross lesion are not overlooked.

  3. Central nervous system mechanisms contributing to the cachexia-anorexia syndrome.

    The cachexia-anorexia syndrome occurs in chronic pathophysiologic processes including cancer, infection with human immunodeficiency virus, bacterial and parasitic diseases, inflammatory bowel disease, liver disease, obstructive pulmonary disease, cardiovascular disease, and rheumatoid arthritis. Cachexia makes an organism susceptible to secondary pathologies and can result in death. Cachexia-anorexia may result from pain, depression or anxiety, hypogeusia and hyposmia, taste and food aversions, chronic nausea, vomiting, early satiety, malfunction of the gastrointestinal system (delayed digestion, malabsorption, gastric stasis and associated delayed emptying, and/or atrophic changes of the mucosa), metabolic shifts, cytokine action, production of substances by tumor cells, and/or iatrogenic causes such as chemotherapy and radiotherapy. The cachexia-anorexia syndrome also involves metabolic and immune changes (mediated by either the pathophysiologic process, i.e., tumor, or host-derived chemical factors, e.g., peptides, neurotransmitters, cytokines, and lipid-mobilizing factors) and is associated with hypertriacylglycerolemia, lipolysis, and acceleration of protein turnover. These changes result in the loss of fat mass and body protein. Increased resting energy expenditure in weight-losing cachectic patients can occur despite the reduced dietary intake, indicating a systemic dysregulation of host metabolism. During cachexia, the organism is maintained in a constant negative energy balance. This can rarely be explained by the actual energy and substrate demands by tumors in patients with cancer. Overall, the cachectic profile is significantly different than that observed during starvation. Cachexia may result not only from anorexia and a decreased caloric intake but also from malabsorption and losses from the body (ulcers, hemorrhage, effusions). In any case, the major deficit of a cachectic organism is a negative energy balance. Cytokines are proposed to participate

    Full Text Available BackgroundRestrictive respiratory failure is a major cause of morbidity and mortality in neuromuscular diseases (NMD. Home mechanical ventilation (HMV is used to treat hypoventilation, and its efficiency is mostly assessed by daytime blood gases or nocturnal oxygen saturation monitoring (SpO2. Non-invasive transcutaneous measure of CO2 (TcCO2 allows to directly assess nocturnal hypercapnia and to detect residual hypoventilation with a higher sensitivity than SpO2.We aimed to compare the prognostic value of nocturnal SpO2 and TcCO2 in ventilated adult NMD patients. MethodsAll consecutive capno-oximetries performed between 2010 and 2011 in ventilated adult NMD patients were analysed retrospectively. Concomitant blood gas analysis and lung function data were collected. Patients on oxygen therapy were excluded. Nocturnal hypoxemia and hypercapnia (using 4 different definitions at baseline were compared in their ability to predict mortality and respiratory events requiring ICU admission during follow-up. ResultsData from 55 patients were analysed (median age 28 IQR 25 - 36.5 years; 71% Duchenne muscular dystrophy; vital capacity 12 7 - 27 % of predicted; 51% tracheostomy.Capno-oxymetry showed hypoxemia in 14.5% and hypercapnia in 12.7 to 41.8%, according to the used definition.Over a follow-up lasting up to 5 years (median 4.0 3.6 - 4.5 years, we observed 12 deaths and 20 respiratory events requiring ICU admission. Hypercapnia was significantly associated with the study outcomes, with TcCO2 >49 mmHg during ≥10% of the time being the best definition, whilst hypoxemia was not.ConclusionsOur data show for the first time that residual hypoventilation, assessed by capnometry, is significantly associated with negative outcomes in adult ventilated NMD patients, whilst oximetry is not. Accordingly, we suggest capnometry to be included in the systematic assessment of HMV efficiency in NMD patients.

    Full Text Available We describe the case of a 12-year-old boy who developed temporal lobe epilepsy (TLE with daily complex partial seizures (CPS and monthly generalized seizures. Moreover, he frequently snored while asleep since early childhood. Polysomnography (PSG revealed severe obstructive sleep apnea with apnea–hypopnea index (AHI of 37.8/h. Video-PSG with simultaneous electroencephalography (EEG recording captured two ictal apneic episodes during sleep, without any motor manifestations. The onset of rhythmic theta activity in the midtemporal area on EEG was preceded by the onset of apnea by several seconds and disappeared soon after cessation of central apnea. One episode was accompanied by ictal bradycardia of <48 beats/min which persisted for 50 s beyond the end of epileptic activity. After treatment with carbamazepine and tonsillectomy/adenoidectomy, the seizures were well controlled and AHI decreased to 2.5/h. Paroxysmal discharges also disappeared during this time. Uncontrolled TLE complicated by sleep apnea should be evaluated for the presence of ictal central apnea/bradycardia.

    2001-04-01

    Effects of histaminergic agonists and antagonists were investigated on withdrawal signs in lorazepam-dependent rats. Physical dependence was developed by giving lorazepam admixed with the food in the following dose schedule (in mg/kg given daily x days): 10 x 4, 20 x 4, 40 x 4, 80 x 4, and 120 x 7. The parameters observed during the periods of administration of lorazepam and after its withdrawal were spontaneous locomotor activity (SLA), reaction time to pain, foot shock aggression (FSA), and audiogenic seizures. During the withdrawal period, the rats were divided into groups of 10 each. Control-withdrawal group did not receive any drug. The drugs (in mg/kg administered intramuscularly)--L-histidine (50), histamine-N-methyl (2), promethazine (10), pheniramine (10), astemizole (10), and thioperamide (1)--were given separately in other groups daily during the withdrawal period. The withdrawal signs in control group were hyperkinesia, hyperaggression, and audiogenic seizures. L-Histidine, precursor of histamine, and thioperamide, antagonist of H3 receptor, potentiated hyperkinesia, hyperaggression, and audiogenic seizures. Histamine-N-methyl, agonist of H3 receptor, and H1 receptor antagonists, promethazine and pheniramine, blocked all the withdrawal signs. Astemizole, a peripheral antagonist of H1 receptor, could not affect any withdrawal sign. It may be concluded that histamine H1 receptors are facilitatory and H3 receptors are inhibitory for benzodiazepine (BZD) withdrawal syndrome.

    Objective: To describe a patient with a right-sided supranuclear facial palsy and concomitant sicca keratopathy of the right eye following right-sided dorsolateral medullary infarction. Methods: Our patient underwent a complete ophthalmologic and neurologic examination including biomicroscopy, fundus examination, cranial nerve examination, Shirmer I test, and magnetic resonance imaging of the brain. Results: A 61-year-old woman presented in emergency with a central facial nerve palsy on the right side and truncal ataxia. Neurologic assessment revealed a concurrent dysphagia, dysarthria, hypoesthesia of the right face, and weakness of the right upper limb. Magnetic resonance imaging of the brain showed an old left-sided cerebellar infarction, but a recent ischemic infarction at the level of the right dorsolateral medulla oblongata was the cause of our patient’s current problems. One month after diagnosis of the right-sided dorsolateral medullary syndrome, there were complaints of ocular irritation and a diminished visual acuity in the right eye. Biomicroscopy showed a sicca keratopathy with nearly complete absence of tear secretion on the Shirmer I test, but with normal eye closure and preserved corneal reflexes and sensitivity. Conclusion: A dorsolateral medullary syndrome can have a variable expression in symptomatology. Our case is special because of the combination of an ipsilateral supranuclear facial palsy with normal upper facial muscle function together with an ipsilateral sicca keratopathy as a result of a nearly absent tear secretion. We hypothesized that the mechanism underlying the patient’s sicca keratopathy ipsilateral to the supranuclear facial palsy involved the superior salivatory nucleus, which is situated in the caudal pons inferiorly of the motor facial nucleus and is most probably affected by a superior extension of the infarcted area in the right medulla oblongata.

    Central anticholinergic syndrome (CAS) following general anesthesia (GA) is a well known syndrome in children and adults. Many cases of CAS have been previously reported in the literature. However, there are only two reports of post resuscitation CAS after administration of small doses of atropine. Hereby, we report a case of CAS in a child undergoing complete dental restoration under GA after receiving a small dose of atropine to reverse hypoxia induced bradycardia. Intraoperative events such as hypoxia or cardiac arrest may play a role as triggers for CAS. However, we cannot establish a causal relationship between the occurrence of CAS and such critical events.

    We describe a case of a 49-year-old woman with stage-IIIB lung adenocarcinoma who experienced an acute superior vena cava syndrome related to an implanted central venous catheter without associated venous thrombosis. The catheter was surgically implanted for chemotherapy. Superior vena cava syndrome appeared after the procedure and was due to insertion of the catheter through a subclinical stenosis of the superior vena cava. Complete resolution of the patient's symptoms was obtained using stent placement and endovascular repositioning of the catheter tip. (orig.)

    Key words: Cerebrovascular Acute Radiation Syndrome (Cv ARS), Radiation Neurotoxins (RNT), Neurotransmitters, Radiation Countermeasures, Antiradiation Vaccine (ArV), Antiradiation Blocking Antibodies, Antiradiation Antidote. Psychoneuroimmunology, Neurotoxicity. ABSTRACT: To review the role of Radiation Neurotoxins in triggering, developing of radiation induced central nervous system injury. Radiation Neurotoxins - rapidly acting blood toxic lethal agent, which activated after irradiation and concentrated, circulated in interstitial fluid, lymph, blood with interactions with cell membranes, receptors and cell compartments. Radiation Neurotoxins - biological molecules with high enzymatic activity and/or specific lipids and activated or modified after irradiation. The Radiation Neurotoxins induce increased permeability of blood vessels, disruption of the blood-brain barrier, blood-cerebrospinal fluid (CSF) barrier and developing severe disorder of blood macro- and micro-circulation. Principles of Radiation Psychoneuro-immunology and Psychoneuro-allergology were applied for determination of pathological processes developed after irradiation or selective administration of Radiation Neurotoxins to radiation naïve mammals. Effects of radiation and exposure to radiation can develop severe irreversible abnormalities of Central Nervous System, brain structures and functions. Antiradiation Vaccine - most effective, advanced methods of protection, prevention, mitigation and treatment and was used for of Acute Radiation Syndromes and elaboration of new technology for immune-prophylaxis and immune-protection against ϒ, Heavy Ion, Neutron irradiation. Results of experiments suggested that blocking, antitoxic, antiradiation antibodies can significantly reduce toxicity of Radiation Toxins. New advanced technology include active immune-prophylaxis with Antiradiation Vaccine and Antiradiation therapy that included specific blocking antibodies to Radiation Neurotoxins

    Energy homoeostasis is maintained through a complex interplay of nutrient intake and energy expenditure. The central nervous system is an essential component of this regulation, as it integrates circulating signals of hunger and satiety to develop adaptive responses at the behavioural and metabolic levels, while the hypothalamus is regarded as a particularly crucial structure in the brain in terms of energy homoeostasis. The arcuate nucleus (ARC) of the hypothalamus contains at least two intermingled neuronal populations: the neurons that produce neuropeptide Y (NPY); and the Agouti-related protein (AgRP) produced by AgRP/NPY neurons situated below the third ventricle in close proximity to proopiomelanocortin (POMC)-producing neurons. POMC neurons exert their catabolic and anorectic actions by releasing α-melanocyte-stimulating hormone (α-MSH), while AgRP neurons oppose this action by exerting tonic GABAergic inhibition of POMC neurons and releasing the melanocortin receptor inverse agonist AgRP. The release of neurotransmitters and neuropeptides by second-order AgRP neurons appears to take place on a multiple time scale, thereby allowing neuromodulation of preganglionic neuronal activity and subsequent control of nutrient partitioning - in other words, the coordinated regulation of conversion, storage and utilization of carbohydrates vs. lipids. This suggests that the function of AgRP neurons extends beyond the strict regulation of feeding to the regulation of efferent organ activity, such that AgRP neurons may now be viewed as an important bridge between central detection of nutrient availability and peripheral nutrient partitioning, thus providing a mechanistic link between obesity and obesity-related disorders.

    Objective In acute respiratory distress syndrome (ARDS), conservative fluid management increases ventilator-free days without affecting mortality. Response to fluid management may differ based on patients’ initial central venous pressure (CVP). We hypothesized initial CVP would modify the effect of fluid management on outcomes. Design Retrospective analysis of the Fluid and Catheter Treatment Trial, a multicenter randomized trial comparing conservative to liberal fluid management in ARDS. We examined the relationship between initial CVP, fluid strategy, and 60-day mortality in univariate and multivariable analysis. Setting Twenty acute care hospitals. Patients Nine hundred and thirty-four ventilated ARDS patients with a CVP available at enrollment, 609 without baseline shock (for whom fluid balance was managed by study protocol). Interventions None. Measurements and Main Results Among patients without baseline shock, those with initial CVP > 8 mmHg experienced similar mortality with conservative and liberal fluid management (18% versus 18%, p=0.928), whereas those with CVP ≤8 mmHg experienced lower mortality with a conservative strategy (17% versus 36%, p=0.005). Multivariable analysis demonstrated an interaction between initial CVP and the effect of fluid strategy on mortality (p=0.031). At higher initial CVPs, the difference in treatment between arms was predominantly furosemide administration, which was not associated with mortality (p=0.122). At lower initial CVPs, the difference between arms was predominantly fluid administration, with additional fluid associated with increased mortality (p=0.013). Conclusions Conservative fluid management decreases mortality for ARDS patients with a low initial central venous pressure. In this population, the administration of intravenous fluids appears to increase mortality. PMID:26741580

    Full Text Available Abstract Background Metabolic syndrome (MetS is composed of cardiovascular risk factors including insulin resistance, obesity, dyslipidemia, and hypertension. Most of the components of MetS have been linked to the development of neoplasm. The purpose of this study was to evaluate the relationship between individual components of MetS and colorectal adenoma. Methods The study subjects were recruited from a pool of 4872 individuals who underwent a health check-up examination during the period January 2006 to May 2008. Each participant fulfilled a structured questionnaire. MetS was defined based on the America Heart Association and National Heart Lung Blood Institute criteria. Subjects with history of colon cancer, colon polyps, colitis, or prior colonic surgery were excluded. Results A total of 4122 subjects were included for final analysis (2367 men and 1755 women; mean age, 49.6 ± 11.7 years. Of them, MetS was diagnosed in 708 men (29.9% and in 367 women (20.9%. Among the patients with MetS, 34.6% had adenoma, 31.7% had hyperplastic polyps and 23.3% were polyp-free (p Conclusions Of the components of MetS analyzed in this study, central obesity and dyslipidemia are independent risk factors for colorectal adenoma. With regard to the prevention of colorectal neoplasm, life-style modification such as weight reduction is worthwhile.

    Full Text Available Central corneal thickness (CCT, one of the most highly heritable human traits (h(2 typically>0.9, is important for the diagnosis of glaucoma and a potential risk factor for glaucoma susceptibility. We conducted genome-wide association studies in five cohorts from Australia and the United Kingdom (total N = 5058. Three cohorts were based on individually genotyped twin collections, with the remaining two cohorts genotyped on pooled samples from singletons with extreme trait values. The pooled sample findings were validated by individual genotyping the pooled samples together with additional samples also within extreme quantiles. We describe methods for efficient combined analysis of the results from these different study designs. We have identified and replicated quantitative trait loci on chromosomes 13 and 16 for association with CCT. The locus on chromosome 13 (nearest gene FOXO1 had an overall meta-analysis p-value for all the individually genotyped samples of 4.6x10(-10. The locus on chromosome 16 was associated with CCT with p = 8.95x10(-11. The nearest gene to the associated chromosome 16 SNPs was ZNF469, a locus recently implicated in Brittle Cornea Syndrome (BCS, a very rare disorder characterized by abnormal thin corneas. Our findings suggest that in addition to rare variants in ZNF469 underlying CCT variation in BCS patients, more common variants near this gene may contribute to CCT variation in the general population.

    We report a 21-year-old woman presenting with a slowly progressive tetraparesis, optic nerve atrophy on both sides, and autonomic disturbances since early childhood. The patient has been carefully followed up for 5 years with clinical and ancillary investigations. The results and the time course strongly suggest an underlying degenerative syndrome affecting parts of three major systems: autonomic, motor and visual. Some symptoms resemble familial dysautonomia (FD, Riley-Day syndrome), however, hallmarks of FD, such as absence of fungiform papillae of the tongue, abnormal reaction on intradermal histamine injection, absent tendon reflexes, are missing, and central motor disturbances have not been described in FD. We consider this syndrome a slowly progressive multisystemic degeneration with two unusual hitherto unreported features: the combination of affected systems (autonomic and motor systems, optic nerves), and the early onset.

    Split-night polysomnography is performed at our centre in all patients with ALS who require assessment for nocturnal hypoventilation and their response to non-invasive ventilation. The purpose of this study was to determine how successful this practice has been, reflected by whether a complete assessment was achieved by a single split-night polysomnogram. We undertook a systematic, retrospective review of all consecutive split-night polysomnograms in ALS patients between 2005 and 2012. A total of 47 cases were reviewed. Forty-three percent of patients had an incomplete test, resulting in a recommendation to repeat the polysomnogram. Poor sleep efficiency and absence of REM sleep in the diagnostic portion of the study were strongly associated with incomplete studies. Clinical variables that reflect severity of ALS (FVC, PaCO2, ALSFRS-R) and use of REM-suppressing antidepressants or sedative-hypnotics were not associated with incomplete split-night polysomnogram. In conclusion, a single, split-night polysomnogram is frequently inconclusive for the assessment of nocturnal hypoventilation and complete titration of non-invasive positive pressure ventilation in patients with ALS. Poor sleep efficiency and absence of REM sleep are the main limitations of split-night polysomnography in this patient population.

    A 12-week-old boy with Jeune syndrome (asphyxiating thoracic dystrophy) was referred to the orthopaedic unit with progressive respiratory failure, recurrent respiratory tract infections, and recurrent admissions to the intensive care unit for ventilatory support. His chest x-ray revealed a small and narrow thoracic cage with short broad ribs and abnormal costal cartilages. His chest expansion was impaired by the short, horizontally positioned ribs resulting in alveolar hypoventilation. Without surgical intervention to expand his thoracic cage, he would die of respiratory failure.

  2. Imbalance between thyroid hormones and the dopaminergic system might be central to the pathophysiology of restless legs syndrome: a hypothesis

    Jose Carlos Pereira Jr.

    2010-01-01

    Full Text Available Data collected from medical literature indicate that dopaminergic agonists alleviate Restless Legs Syndrome symptoms while dopaminergic agonists antagonists aggravate them. Dopaminergic agonists is a physiological regulator of thyroid-stimulating hormone. Dopaminergic agonists infusion diminishes the levels of thyroid hormones, which have the ability to provoke restlessness, hyperkinetic states, tremors, and insomnia. Conditions associated with higher levels of thyroid hormones, such as pregnancy or hyperthyroidism, have a higher prevalence of Restless Legs Syndrome symptoms. Low iron levels can cause secondary Restless Legs Syndrome or aggravate symptoms of primary disease as well as diminish enzymatic activities that are involved in dopaminergic agonists production and the degradation of thyroid hormones. Moreover, as a result of low iron levels, dopaminergic agonists diminishes and thyroid hormones increase. Iron therapy improves Restless Legs Syndrome symptoms in iron deprived patients. Medical hypothesis. To discuss the theory that thyroid hormones, when not counterbalanced by dopaminergic agonists, may precipitate the signs and symptoms underpinning Restless Legs Syndrome. The main cause of Restless Legs Syndrome might be an imbalance between the dopaminergic agonists system and thyroid hormones.

    Full Text Available Both central (CNS and peripheral nervous system (PNS complications are frequent and varied in connective tissue diseases. A systematic review was conducted between 1989 and 2014 in the databases Medline, Scopus, and Cochrane Library using the search terms, peripheral and central nervous complications and immunological profiles, to identify studies in specific connective tissue disorders such as rheumatoid arthritis, systemic lupus erythematosus, and primary Sjögren’s syndrome. A total of 675 references were identified, of which 118 were selected for detailed analysis and 22 were included in the final review with a total of 2338 participants. Our search focused only on studies upon connective tissue disorders such as rheumatoid arthritis, systemic lupus erythematosus, and primary Sjögren’s syndrome associated with seroimmunological data. The reported prevalence of CNS involvement ranges from 9 to 92% across the reported studies. However, the association between CNS and PNS manifestations and seroimmunological profiles remains controversial. Τo date, no laboratory test has been shown as pathognomonic neither for CNS nor for PNS involvement.

    Dysarthria-clumsy hand stroke syndrome has been described frequently in adults but not in children. We report a 15-year-old right-handed boy with sudden onset of dysarthria, dysphagia, right facial weakness, and mild right-hand clumsiness. Computed tomographic scan and magnetic resonance imaging demonstrated infarction in the genu and posterior limb of the left internal capsule. Magnetic resonance angiography and conventional angiography demonstrated stenosis of the supraclinoid portion of the left internal carotid artery and the origin of the left ophthalmic artery. Lacunar infarction in an older adult is not the only mechanism leading to dysarthria-clumsy hand syndrome.

    Full Text Available Aim. To evaluate whether body fat distribution, birth weight, and family history for diabetes (FHD were associated with metabolic syndrome (MetS in children and adolescents. Methods. A total of 439 Italian obese children and adolescents (5–18 years were enrolled. Subjects were divided into 2 groups: prepubertal and pubertal. MetS was diagnosed according to the adapted National Cholesterol Education Program criteria. Birth weight percentile, central obesity index (measured by dual-energy X-ray absorptiometry, insulin sensitivity (ISI, and disposition index were evaluated. Multivariate logistic regression models were used to determine variables associated with MetS. Results. The prevalence of MetS was 17%, with higher percentage in adolescents than in children (21 versus 12%. In the overall population, central obesity index was a stronger predictor of MetS than insulin sensitivity and low birth weight. When the two groups were considered, central fat depot remained the strongest predictor of MetS, with ISI similarly influencing the probability of MetS in the two groups and birth weight being negatively associated to MetS only in pubertal individuals. Neither FHD nor degree of fatness was a significant predictor of MetS. Conclusion. Simple clinical parameters like increased abdominal adiposity and low birth weight could be useful tools to identify European obese adolescents at risk for metabolic complications.

  9. Stiff-person syndrome (SPS) and anti-GAD-related CNS degenerations: protean additions to the autoimmune central neuropathies.

    Ali, Fatima; Rowley, Merrill; Jayakrishnan, Bindu; Teuber, Suzanne; Gershwin, M Eric; Mackay, Ian R

    2011-09-01

    Stiff Person Syndrome (SPS) is a rare autoimmune neurological disease attributable to autoantibodies to glutamic acid decarboxylase (anti-GAD) more usually associated with the islet beta cell destruction of autoimmune type 1 diabetes (T1D). SPS is characterized by interference in neurons with the synthesis/activity of the inhibitory neurotransmitter gamma amino butyric acid (GABA) resulting in the prototypic progressive spasmodic muscular rigidity of SPS, or diverse neurological syndromes, cerebellar ataxia, intractable epilepsy, myoclonus and several others. Remarkably, a single autoantibody, anti-GAD, can be common to widely different disease expressions, i.e. T1D and SPS. One explanation for these data is the differences in epitope engagement between the anti-GAD reactivity in SPS and T1D: in both diseases, anti-GAD antibody reactivity is predominantly to a conformational epitope region in the PLP- and C-terminal domains of the 65 kDa isoform but, additionally in SPS, there is reactivity to conformational epitope(s) on GAD67, and short linear epitopes in the C-terminal region and at the N-terminus of GAD65. Another explanation for disease expressions in SPS includes ready access of anti-GAD to antigen sites due to immune responsiveness within the CNS itself according to intrathecal anti-GAD-specific B cells and autoantibody. Closer study of the mysterious stiff-person syndrome should enhance the understanding of this disease itself, and autoimmunity in general.

    Full Text Available BackgroundHigh-sensitivity C-reactive protein (hsCRP has been shown to predict cardiovascular disease (CVD endpoints and is associated with CVD risk factors and the metabolic syndrome. This study evaluated the association between hsCRP and CVD risk factors among Afro-Caribbean young adults in Jamaica. MethodsWe conducted a cross-sectional analysis of data from the Jamaica 1986 Birth Cohort Study. Data were collected between 2005 and 2007 when participants were 18-20 years old. All participants completed an interviewer administered questionnaire and had anthropometric and blood pressure (BP measurements performed. Fasting blood samples were collected for measurement of glucose, lipids and hsCRP. Logistic regression models were used to identify factors independently associated with high hsCRP.ResultsAnalyses included 342 men and 404 women with mean age 18.8 ± 0.6 years. Approximately 15% of the participants had high risk hsCRP (>3 mg/L, with a higher prevalence among women (20% vs. 9%; p<0.001. The prevalence of elevated hsCRP increased with BMI category, high waist circumference (WC, high triglycerides, low HDL, and lower parental education among women, but only for high WC and lower parental education among men. In logistic regression models controlling for sex and parental education, high WC was associated with significantly higher odds of high hsCRP (OR 7.8, 95%CI 4.8-12.9, p<0.001. In a similar model high hsCRP was also associated with the number of metabolic syndrome components. Compared to participants with no metabolic syndrome component, having one metabolic syndrome component was associated with a two-fold higher odds of high hsCRP (OR 2.2, 95%CI 1.3-3.8, p=0.005, while having three components was associated with a fourteen-fold higher odds of high hsCRP (OR 13.5, 95%CI 2.4-76.0, p<0.001. ConclusionHigh hsCRP is common among Jamaican young adults and is strongly associated with central obesity and the number of metabolic syndrome

    IRIS is described as a paradoxical deterioration of clinical status upon initiation of combined anti-retroviral therapy (cART) in patients with HIV infection. Immune reconstitution inflammatory syndrome (CNS-IRIS) involving the central nervous system is rarely reported. We describe the case of 57-year-old man who developed a fatal case of CNS- IRIS. A rapid deterioration of neurological status was associated with progression of patchy T2-weighted hyperintensities involving different vascular territories on brain MRI. Diagnosis of CNS-IRIS is based of laboratory and radiologic findings, however brain biopsy is supportive. Despite immune restoration being involved in clinical deterioration, discontinuation of cART is not recommended. The use of corticosteroids is highly controversial. Prompt recognition of CNS-IRIS is crucial for preventing neurological complications and ensuing sequelae.

    In this 71-year-old man diagnosed as obstructive sleep apnea syndrome initially, the apnea-hypopnea index in polysomnography was 31.3/hour. He started auto-adjusted continuous positive airway pressure (auto-CPAP) treatment in July 2005 but developed congestive heart failure in December 2007. Pulmonary arterial pressure (PAP), estimated by echocardiography, was 71 mmHg. In January 2008, during simplified sleep examination with a breath-movement sensor under auto-CPAP, many central-type apneas were recognized. After replacing auto-CPAP with adaptive servo-ventilation (ASV), the apnea-hypopnea index was 5.3/hour and PAP became 36 mmHg after 3 months. It was thought that the increase of PAP was due to long-term inadequate use of auto-CPAP.

    Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

    We've estimated the cellular and metabolic part of geroprophylactic effects of short synthetic tripeptides vesugen and pinealon for correction of the biological age. 32 people (18 men, 12 women) aged 41-83 years with polymorbidity and the organic brain syndrome in remission participated in the study. The preparations of "Pinealon" and "Vesugen" have had the significant anabolic effect. They have improved the activity of the Central nervous system and other vital organs, which slows the rate of aging by biological age indicators. Vesugen has demonstrated more visible geroprophylactic effect than Pinealon. At the same time we've found the prooxidant activity through chemiluminescence. Decrease of markers CD34+ positive hematopoietic polypotent cells in blood has shown significant inhibition of hemopoiesis. Apparently, the cells have not been involved in the adaptive reactions. Pinealon and Vesugen haven't affected the degree of chromatin condensation, so they are safe on nuclear genetic level. This property should be studied in future. In geriatric practice, we recommend to apply the peptides Pinealon and Vesugen as geroprotectors anabolic neuroprotective and no antioxidant type for reducing the rate of aging in patients with the organic brain syndrome vascular and/or traumatic genesis.

    Conclusions: Central dopamine dysregulation during VWR reinforces the link between MC4R function and molecular and behavioral responding to rewards. The data also suggest that exercise can be a successful lifestyle intervention in MC4R-haploinsufficient individuals despite reduced positive reinforcement during exercise training.

    Here, we present a neuroendocrine concept to review the circularly interacting energy homeostasis system between brain and body. Body-brain interaction is circular because the brain immediately integrates an input to an output, and because part of this response may be that the brain modulates the sensitivity of this perception. First, we describe how the brain senses the body through neurons and blood-borne factors. Direct neuronal connections report the state of various organs. In addition, humoral factors are perceived by the blood-brain barrier and circumventricular organs. We describe how circulating energy carriers are sensed and what signals reach the brain during food intake, exercise and an immune response. We describe that the brain regulates the homeostatic process at two fundamentally different levels during the active and inactive states. The unbalanced output of the brain in the metabolic syndrome is discussed in relation with such circadian rhythms and with regional activity of the autonomic nervous system. In line with the above, we suggest a new approach for the diagnosis and therapy of the metabolic syndrome.

    Unclassified sudden infant death (USID) is the sudden and unexpected death of an infant that remains unexplained after thorough case investigation including performance of a complete autopsy and review of the circumstances of death and the clinical history. When the infant is below 1 year of age and with onset of the fatal episode apparently occurring during sleep, this is referred to as sudden infant death syndrome (SIDS). USID and SIDS remain poorly understood despite the identification of several environmental and some genetic risk factors. In this study, we investigated genetic risk factors involved in the autonomous nervous system in 195 Dutch USID/SIDS cases and 846 Dutch, age-matched healthy controls. Twenty-five DNA variants from 11 genes previously implicated in the serotonin household or in the congenital central hypoventilation syndrome, of which some have been associated with SIDS before, were tested. Of all DNA variants considered, only the length variation of the polyalanine repeat in exon 3 of the PHOX2B gene was found to be statistically significantly associated with USID/SIDS in the Dutch population after multiple test correction. Interestingly, our data suggest that contraction of the PHOX2B exon 3 polyalanine repeat that we found in six of 160 SIDS and USID cases and in six of 814 controls serves as a probable genetic risk factor for USID/SIDS at least in the Dutch population. Future studies are needed to confirm this finding and to understand the functional effect of the polyalanine repeat length variation, in particular contraction, in exon 3 of the PHOX2B gene.

    We report the case of a 49-years-old patient who presented to the accident and emergency department with sudden onset dyspnea associated with acute shoulder pain. He was breathless at rest with supine hypoxemia. He had an amyotrophic left shoulder with localized paresis of the shoulder. Both hemi-diaphragms were elevated on chest X-rays. Pulmonary function tests showed a restrictive pattern and both phrenic nerve conduction velocities were decreased. At night, alveolar hypoventilation was evidenced by elevated mean capnography (PtcCO2: 57mmHg). Neuralgic amyotrophy, Parsonage-Turner syndrome was the final diagnosis. This syndrome is a brachial plexus neuritis with a predilection for the suprascapular and axillary nerves. Phrenic nerve involvement is rare but where present can be the most prominent clinical feature as in our case report.

    The aim of the current study was to identify whether hyperexcitability of the central nervous system is a prognostic factor for individuals with carpal tunnel syndrome (CTS) likely to experience rapid and clinical self-reported improvement following a physical therapy program including soft tissue mobilization and nerve slider neurodynamic interventions. Women presenting with clinical and electrophysiological findings of CTS were involved in a prospective single-arm trial. Participants underwent a standardized examination and then a physical therapy session. The physical therapy sessions included both soft tissue mobilization directed at the anatomical sites of potential median nerve entrapment and a passive nerve slider neurodynamic technique targeted to the median nerve. Pressure pain thresholds (PPT) over the median, radial and ulnar nerves, C5-C6 zygapophyseal joint, carpal tunnel and tibialis anterior muscle were assessed bilaterally. Additionally, thermal detection and pain thresholds were measured over the carpal tunnel and thenar eminence bilaterally to evaluate central nervous system excitability. Subjects were classified as responders (having achieved a successful outcome) or non-responders based on self-perceived recovery. Variables were entered into a stepwise logistic regression model to determine the most accurate variables for determining prognosis. Data from 72 women were included in the analysis, of which 35 experienced a successful outcome (48.6%). Three variables including PPT over the C5-C6 joint affected side 66 points were identified. If 2 out of 3 variables were present (LR + 14.8), the likelihood of success increased from 48.6 to 93.3%. We identified 3 factors that may be associated with a rapid clinical response to both soft tissue mobilization and nerve slider neurodynamic techniques targeted to the median nerve in women presenting with CTS. Our results support that widespread central sensitization may not be present in women with CTS who

    Extracerebral and cerebral pathology in AIDS (with particular emphasis on the opportunistic infections). The Authors present the extracerebral pathology of 27 cases of AIDS observed at the Department of Pathology of Milan and the cerebral pathology of 80 cases of AIDS collected by three Institutes (Department of Pathology of Milan, Department of Pathology of Rimini and Department of Neuropathology of Münster) with particular emphasis on the pathology of the opportunistic infections. In the adults' group, the most frequent infections are the protozoan ones (T. gondii) followed with equal incidence by the viral and fungal diseases. In the pediatric group the viral diseases are the most frequently seen. Almost all of the adults show multiple infections in the same organ or in different organs. Diffuse lesions with heavy pathologic fields were observed also without tissue reaction. As to cerebral pathology AIDS' patients with opportunistic infections show focal symptoms, whereas the so called "subacute microglial encephalitis" generally appears as a demential syndrome. In cases with progressive multifocal leukoencephalopathy JC virus was always found and in one case also SV 40 - and BK virus. The diffuse demyelinization in some cases of HIV-Encephalopathy is aspecific. In HIV-positive newborns with cerebral signs, the lesions are characterized by oedema, spongiosis and microcalcifications of the basal ganglia; these are aspecific lesions which can be found in toxic and infectious encephalopathies.

    Full Text Available Rett syndrome (RTT is a rare neurodevelopmental disorder, characterized by severe behavioral and physiological symptoms. Mutations in the methyl CpG binding protein 2 gene (MECP2 cause more than 95% of classic cases, and currently there is no cure for this devastating disorder. Recently we have demonstrated that specific behavioral and brain molecular alterations can be rescued in MeCP2-308 male mice, a RTT mouse model, by pharmacological stimulation of the brain serotonin receptor 7 (5-HT7R. This member of the serotonin receptor family – crucially involved in the regulation of brain structural plasticity and cognitive processes – can be stimulated by systemic repeated treatment with LP-211, a brain-penetrant selective 5-HT7R agonist. The present study extends previous findings by demonstrating that the LP-211 treatment (0.25 mg/kg, once per day for 7 days rescues RTT-related phenotypic alterations, motor coordination (Dowel test, spatial reference memory (Barnes maze test and synaptic plasticity (hippocampal long-term-potentiation in MeCP2-308 heterozygous female mice, the genetic and hormonal milieu that resembles that of RTT patients. LP-211 also restores the activation of the ribosomal protein S6, the downstream target of mTOR and S6 kinase, in the hippocampus of RTT female mice. Notably, the beneficial effects on neurobehavioral and molecular parameters of a seven-day long treatment with LP-211 were evident up to two months after the last injection, thus suggesting long-lasting effects on RTT-related impairments. Taken together with our previous study, these results provide compelling preclinical evidence of the potential therapeutic value for RTT of a pharmacological approach targeting the brain 5-HT7R.

  3. Development of central nervous system autoimmunity is impaired in the absence of Wiskott-Aldrich syndrome protein.

    Directory of Open Access Journals (Sweden)

    Marita Bosticardo

    Full Text Available Wiskott-Aldrich Syndrome protein (WASP is a key regulator of the actin cytoskeleton in hematopoietic cells. Defective expression of WASP leads to multiple abnormalities in different hematopoietic cells. Despite severe impairment of T cell function, WAS patients exhibit a high prevalence of autoimmune disorders. We attempted to induce EAE, an animal model of organ-specific autoimmunity affecting the CNS that mimics human MS, in Was(-/- mice. We describe here that Was(-/- mice are markedly resistant against EAE, showing lower incidence and milder score, reduced CNS inflammation and demyelination as compared to WT mice. Microglia was only poorly activated in Was(-/- mice. Antigen-induced T-cell proliferation, Th-1 and -17 cytokine production and integrin-dependent adhesion were increased in Was(-/- mice. However, adoptive transfer of MOG-activated T cells from Was(-/- mice in WT mice failed to induce EAE. Was(-/- mice were resistant against EAE also when induced by adoptive transfer of MOG-activated T cells from WT mice. Was(+/- heterozygous mice developed an intermediate clinical phenotype between WT and Was(-/- mice, and they displayed a mixed population of WASP-positive and -negative T cells in the periphery but not in their CNS parenchyma, where the large majority of inflammatory cells expressed WASP. In conclusion, in absence of WASP, T-cell responses against a CNS autoantigen are increased, but the ability of autoreactive T cells to induce CNS autoimmunity is impaired, most probably because of an inefficient T-cell transmigration into the CNS and defective CNS resident microglial function.

    2016-08-05

    Smith-Magenis syndrome (SMS) is a rare genetic neurodevelopmental disorder characterised by behavioural disturbances, intellectual disability and early onset obesity. The physical features of this syndrome are well characterised; however, behavioural features, such as sleep disturbance, are less well understood and difficult to manage. Sleep issues in SMS are likely due to a combination of disturbed melatonin cycle, facial anatomy and obesity-related ventilatory problems. Sleep disorders can be very distressing to patients and their families, as exemplified by our patient's experience, and can worsen behavioural issues as well as general health. This case demonstrates the successful use of non-invasive ventilation in treating underlying obesity hypoventilation syndrome and obstructive sleep apnoea. As a consequence of addressing abnormalities in sleep patterns, some behavioural problems improved.

    OBJECTIVE The aim of this paper was to compare the severity of the initial neurological injury as well as the early changes in the American Spinal Injury Association (ASIA) motor score (AMS) between central cord syndrome (CCS) patients with and without an increased T2 signal intensity in their spinal cord. METHODS Patients with CCS were identified and stratified based on the presence of increased T2 signal intensity in their spinal cord. The severity of the initial neurological injury and the progression of the neurological injury over the 1st week were measured according to the patient's AMS. The effect of age, sex, congenital stenosis, surgery within 24 hours, and surgery in the initial hospitalization on the change in AMS was determined using an analysis of variance. RESULTS Patients with increased signal intensity had a more severe initial neurological injury (AMS 57.6 vs 75.3, respectively, p = 0.01). However, the change in AMS over the 1st week was less severe in patients with an increase in T2 signal intensity (-0.85 vs -4.3, p = 0.07). Analysis of variance did not find that age, sex, Injury Severity Score, congenital stenosis, surgery within 24 hours, or surgery during the initial hospitalization affected the change in AMS. CONCLUSIONS The neurological injury is different between patients with and without an increased T2 signal intensity. Patients with an increased T2 signal intensity are likely to have a more severe initial neurological deficit but will have relatively minimal early neurological deterioration. Comparatively, patients without an increase in the T2 signal intensity will likely have a less severe initial injury but can expect to have a slight decline in neurological function in the 1st week.

    Central line-associated blood stream infections (CLABSI) commonly complicate the care of patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) after allogeneic stem cell transplantation (HCT). We developed a modified CLABSI (MCLABSI) definition that attempts to exclude pathogens usually acquired because of disruption of mucosal barriers during the vulnerable neutropenic period following HCT that are generally included under the original definition (OCLABSI). We conducted a retrospective study of all AML and MDS patients undergoing HCT between August 2009 and December 2011 at the Cleveland Clinic (N = 73), identifying both OCLABSI and MCLABSI incidence. The median age at transplantation was 52 years (range, 16 to 70); 34 had a high (≥3) HCT comorbidity index (HCT-CI); 34 received bone marrow (BM), 24 received peripheral stem cells (PSC), and 15 received umbilical cord blood cells (UCB). Among these 73 patients, 23 (31.5%) developed OCLABSI, of whom 16 (69.6%) died, and 8 (11%) developed MCLABSI, of whom 7 (87.5%) died. OCLABSI was diagnosed a median of 9 days from HCT: 5 days (range, 2 to 12) for UCB and 78 days (range, 7 to 211) for BM/PSC (P < .001). MCLABSI occurred a median of 12 days from HCT, with similar earlier UCB and later BM/PSC diagnosis (P = .030). Risk factors for OCLABSI in univariate analysis included CBC (P < .001), human leukocyte antigen (HLA)-mismatch (P = .005), low CD34(+) count (P = .007), low total nucleated cell dose (P = .016), and non-Caucasian race (P = .017). Risk factors for OCLABSI in multivariable analysis were UCB (P < .001) and high HCT-CI (P = .002). There was a significant increase in mortality for both OCLABSI (hazard ratio, 7.14; CI, 3.31 to 15.37; P < .001) and MCLABSI (hazard ratio, 6.44; CI, 2.28 to 18.18; P < .001). CLABSI is common and associated with high mortality in AML and MDS patients undergoing HCT, especially in UCB recipients and those with high HCT-CI. We propose

    Objective To summarize the experience in diagnosis and treatment of pulmonary hypertension caused by sleep hypoventilation. Methods The clinical data of 4 patients in a family with pulmonary hypertension caused by sleep hypoventilation, full brothers and sisters, 2 (Cases 1 and 2) being treated presently and 2 (Cases 3 and 4) being deceased and traced by family medical history, were retrospectively analyzed. Results Three of the 4 cases (cases 1, 3, and 4) were misdiagnosed as with cor pulmonale combined with pulmonary hypertension, and one case (case 2) was misdiagnosed as with primary pulmonary hypertension. Polysomnography (PSG) revealed alveolar hypoventilation-indueed long period of oxygen desaturation at sleep in Cases 1 and 2, thus confirming the diagnosis. Pulmonary function test showed that the percentage of maximum inspiratory pressure (PImax) in predicted value (51.5% and 20. 9%) and the maximum expiratory pressure (PEmax) in predicted value (51.3% and 29. 6%) decreased, the percentage of mouth occlusion pressure (PO. 1) in predicted value (141% and 133%) compensatively increased, and the respiratory muscle strength decreased in Cases 1 and 2, which suggested that there was neuromuscular disorder in these patients. Treated by noninvasive ventilation the symptoms of these 2 patients were improved and they were discharge at last. Subsequently, they were treated by long-term night noninvasive ventilation at home, and returned to normal work and life. During the follow-up for 22 and 12 months respectively after discharge, PSG showed that the alveolar hypoventilation-induced long period oxygen desataration at sleep had been greatly improved, and echocardiogram showed that the pulmonary pressure was greatly decreased. Conclusion For the patients with unexplained pulmonary hypertension, PSG monitoring and pulmonary function tests such as Plmax, PEmax, and P0. 1 help determine the etiology, and long-term night noninvasive ventilation at home can improve the

    Brown-Vialetto-Van Laere syndrome (BVVLS) is a rare neurological disease characterized by sensorineural hearing loss and multiple cranial nerve palsies, usually involving the VIIth and IXth to XIIth cranial nerves. We describe the clinical and pathological features of a 33-year-old woman with BVVLS. The patient developed progressive exertional dyspnea, with clinical and laboratory findings of right-sided heart failure and pulmonary hypertension. She developed status epilepticus in the setting of cardiac deterioration and respiratory infection, and died of cardiogenic and septic shock. Autopsy disclosed bilateral neuronal loss and gliosis in the inferior colliculi, locus coeruleus and facial and vestibular nuclei. Cor pulmonale is a complication of hypoventilation-induced hypoxia and hypercapnia and had not yet been reported in BVVLS.

    Full Text Available Purpose: Chiari malformation (CM type 1 frequently causes obstructive or central sleep-disordered breathing (SDB in both adults and children, although SDB is relatively rare as a presenting manifestation in the absence of other neurological symptoms. The definitive treatment of symptomatic CM is surgical decompression. We report a case that is, to our knowledge, a novel manifestation of central sleep apnea (CSA due to CM type 1 with severe exacerbation and initial clinical presentation during pregnancy.Methods: Case report from tertiary care comprehensive sleep medicine center with literature review of sleep-disordered breathing manifestations associated with CM type 1. PubMed search was conducted between January 1982 and October 2013. Results: We report a 25-year-old woman with severe central sleep apnea initially presenting during her first pregnancy that eventually proved to be caused by CM type 1. The patient was successfully treated preoperatively by adaptive servoventilation (ASV, with effective resolution of sleep-disordered breathing following surgical decompression, and without recurrence in a subsequent pregnancy.Our literature review found that 58% of CM patients with SDB had OSA alone, 28% had CSA alone, 8 (10% had mixed OSA/CSA, and 6 (8% had hypoventilation. Of CM patients presenting with SDB, 50% had OSA, 42% had CSA, 8% had mixed OSA/CSA, and 10.4% had hypoventilation. We speculate that CSA may develop in CM patients in whom brainstem compression results in excessive central chemoreflex sensitivity with consequent hypocapnic CSA.Conclusions: CM type 1 may present with a diversity of SDB manifestations, and timely recognition and surgical referral are necessary to prevent further neurological deficits. ASV therapy can effectively manage CSA caused by CM type 1, which may initially present during pregnancy.

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

    IGSF1 (Immunoglobulin Superfamily 1) gene defects cause central hypothyroidism and macroorchidism. However, the pathogenic mechanisms of the disease remain unclear. Based on a patient with a full deletion of IGSF1 clinically followed from neonate to adulthood, we investigated a common pituitary origin for hypothyroidism and macroorchidism, and the role of IGSF1 as regulator of pituitary hormone secretion. The patient showed congenital central hypothyroidism with reduced TSH biopotency, over-secretion of FSH at neonatal minipuberty and macroorchidism from 3 years of age. His markedly elevated inhibin B was unable to inhibit FSH secretion, indicating a status of pituitary inhibin B resistance. We show here that IGSF1 is expressed both in thyrotropes and gonadotropes of the pituitary and in Leydig and germ cells in the testes, but at very low levels in Sertoli cells. Furthermore, IGSF1 stimulates transcription of the thyrotropin-releasing hormone receptor (TRHR) by negative modulation of the TGFβ1-Smad signaling pathway, and enhances the synthesis and biopotency of TSH, the hormone secreted by thyrotropes. By contrast, IGSF1 strongly down-regulates the activin-Smad pathway, leading to reduced expression of FSHB, the hormone secreted by gonadotropes. In conclusion, two relevant molecular mechanisms linked to central hypothyroidism and macroorchidism in IGSF1 deficiency are identified, revealing IGSF1 as an important regulator of TGFβ/Activin pathways in the pituitary.

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

    Full Text Available OBJECTIVE: To describe the central nervous system (CNS alterations present in a sample of oculo-auriculo-vertebral spectrum (OAVS patients, trying to correlate them with other clinical features. METHOD: Seventeen patients with diagnosis of OAVS were evaluated. All presented radiological evaluation of the CNS, normal GTG-Banding karyotype and clinical features involving at least two from the four following areas: oro-cranio-facial, ocular, auricular and vertebral. RESULTS: CNS alterations were verified in eight from seventeen patients (47%. Diffuse cerebral hypoplasia, dilated lateral cerebral ventricles (asymptomatic hydrocephalus, corpus callosum dysgenesis and frontal hypodensities were the most frequent abnormalities. Presence of ophthalmologic abnormalities was the only clinical association observed, being significantly more frequent among patients with cerebral alterations (63% versus 11%. CONCLUSION: CNS abnormalities are frequent in patients with OAVS, especially in carriers of ophthalmologic alterations. However, the absence of detectable cerebral abnormalities did not exclude the possibility that these subjects will subsequently present neurological symptoms.OBJETIVO: Descrever as alterações do sistema nervoso central (SNC presentes em uma amostra de pacientes com espectro óculo-aurículo-vertebral (EOAV, tentando correlacioná-las com os demais achados clínicos.

    Full Text Available Abstract Background Complex Regional Pain Syndrome type 1 (CRPS1 is a clinical diagnosis based on criteria describing symptoms of the disease. The main aim of the present study was to compare the sensitivity and specificity of calculation methods used to assess thermographic images (infrared imaging obtained during temperature provocation. The secondary objective was to obtain information about the involvement of the sympathetic system in CRPS1. Methods We studied 12 patients in whom CRPS1 was diagnosed according to the criteria of Bruehl. High and low whole body cooling and warming induced and reduced sympathetic vasoconstrictor activity. The degree of vasoconstrictor activity in both hands was monitored using a videothermograph. The sensitivity and specificity of the calculation methods used to assess the thermographic images were calculated. Results The temperature difference between the hands in the CRPS patients increases significantly when the sympathetic system is provoked. At both the maximum and minimum vasoconstriction no significant differences were found in fingertip temperatures between both hands. Conclusion The majority of CRPS1 patients do not show maximal obtainable temperature differences between the involved and contralateral extremity at room temperature (static measurement. During cold and warm temperature challenges this temperature difference increases significantly. As a result a higher sensitivity and specificity could be achieved in the diagnosis of CRPS1. These findings suggest that the sympathetic efferent system is involved in CRPS1.

    Full Text Available Abstract The vascular endothelial basement membrane and extra cellular matrix is a compilation of different macromolecules organized by physical entanglements, opposing ionic charges, chemical covalent bonding, and cross-linking into a biomechanically active polymer. These matrices provide a gel-like form and scaffolding structure with regional tensile strength provided by collagens, elasticity by elastins, adhesiveness by structural glycoproteins, compressibility by proteoglycans – hyaluronans, and communicability by a family of integrins, which exchanges information between cells and between cells and the extracellular matrix of vascular tissues. Each component of the extracellular matrix and specifically the capillary basement membrane possesses unique structural properties and interactions with one another, which determine the separate and combined roles in the multiple diabetic complications or diabetic opathies. Metabolic syndrome, prediabetes, type 2 diabetes mellitus, and their parallel companion (atheroscleropathy are associated with multiple metabolic toxicities and chronic injurious stimuli. The adaptable quality of a matrix or form genetically preloaded with the necessary information to communicate and respond to an ever-changing environment, which supports the interstitium, capillary and arterial vessel wall is individually examined.

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

    Sea otters (Enhydra lutris) have exceptionally high energetic requirements, which nearly double during lactation and pup care. Thus, females are extremely vulnerable to caloric insufficiency. Despite a number of compensatory strategies, the metabolic challenge of reproduction culminates in numerous maternal deaths annually. Massive depletion of energy reserves results in a case presentation that we define as end-lactation syndrome (ELS), characterized by moderate to severe emaciation not attributable to a concurrent, independent disease process in females dying during late pup care or postweaning. We compiled detailed data for 108 adult female southern sea otters (Enhydra lutris nereis) examined postmortem that stranded in California, US, 2005–12, and assessed pathology, reproductive status, and the location and timing of stranding. We introduce simple, grossly apparent, standardized physical criteria to assess reproductive stage for female sea otters. We also describe ELS, examine associated risk factors, and highlight female life history strategies that likely optimize reproduction and survival. Our data suggest that females can reset both the timing and energetic demands of reproduction through fetal loss, pup abandonment, or early weaning as part of specific physiologic checkpoints during each reproductive cycle. Females appear to preload nutritionally during delayed implantation and gestation to increase fitness and reproductive success. We found that ELS was a major cause of death, affecting 56% of enrolled adult females. Peak ELS prevalence occurred in late spring, possibly reflecting the population trend toward fall/winter pupping. Increasing age and number of pregnancies were associated with a higher risk of ELS. Although the proportion of ELS females was highest in areas with dense sea otter populations, cases were recovered throughout the range, suggesting that death from ELS is associated with, but not solely caused by, population resource limitation.

  13. Prader-Willi Critical Region, a Non-Translated, Imprinted Central Regulator of Bone Mass: Possible Role in Skeletal Abnormalities in Prader-Willi Syndrome.

    Directory of Open Access Journals (Sweden)

    Ee-Cheng Khor

    Full Text Available Prader-Willi Syndrome (PWS, a maternally imprinted disorder and leading cause of obesity, is characterised by insatiable appetite, poor muscle development, cognitive impairment, endocrine disturbance, short stature and osteoporosis. A number of causative loci have been located within the imprinted Prader-Willi Critical Region (PWCR, including a set of small non-translated nucleolar RNA's (snoRNA. Recently, micro-deletions in humans identified the snoRNA Snord116 as a critical contributor to the development of PWS exhibiting many of the classical symptoms of PWS. Here we show that loss of the PWCR which includes Snord116 in mice leads to a reduced bone mass phenotype, similar to that observed in humans. Consistent with reduced stature in PWS, PWCR KO mice showed delayed skeletal development, with shorter femurs and vertebrae, reduced bone size and mass in both sexes. The reduction in bone mass in PWCR KO mice was associated with deficiencies in cortical bone volume and cortical mineral apposition rate, with no change in cancellous bone. Importantly, while the length difference was corrected in aged mice, consistent with continued growth in rodents, reduced cortical bone formation was still evident, indicating continued osteoblastic suppression by loss of PWCR expression in skeletally mature mice. Interestingly, deletion of this region included deletion of the exclusively brain expressed Snord116 cluster and resulted in an upregulation in expression of both NPY and POMC mRNA in the arcuate nucleus. Importantly, the selective deletion of the PWCR only in NPY expressing neurons replicated the bone phenotype of PWCR KO mice. Taken together, PWCR deletion in mice, and specifically in NPY neurons, recapitulates the short stature and low BMD and aspects of the hormonal imbalance of PWS individuals. Moreover, it demonstrates for the first time, that a region encoding non-translated RNAs, expressed solely within the brain, can regulate bone mass in health

  14. ALDH1A1 Deficiency in Gorlin Syndrome Suggests a Central Role for Retinoic Acid and ATM Deficits in Radiation Carcinogenesis.

    We hypothesize that aldehyde dehydrogenase 1A1 (ALDH1A1) deficiency will result in impaired ataxia-telangiectasia mutated (ATM) activation in a retinoic acid-sensitive fashion. Data supporting this hypothesis include (1) reduced ATM activation in irradiated primary dermal fibroblasts from ALDH1A1-deficient Gorlin syndrome patients (GDFs), relative to ALDH1A1-positive normal human dermal fibroblasts (NHDFs) and (2) increased ATM activation by X-radiation in GDFs pretreated with retinoic acid, however, the impact of donor variability on ATM activation in fibroblasts was not assessed and is a prudent consideration in future studies. Clonogenic survival of irradiated cells showed differential responses to retinoic acid as a function of treatment time. Long-term (5 Day) retinoic acid treatment functioned as a radiosensitizer and was associated with downregulation of ATM protein levels. Short-term (7 h) retinoic acid treatment showed a trend toward increased survival of irradiated cells and did not downregulate ATM protein levels. Using a newly developed IncubATR technology, which defines changes in bulk chemical bond patterns in live cells, we can discriminate between the NHDF and GDF phenotypes, but treatment of GDFs with retinoic acid does not induce reversion of bulk chemical bond patterns associated with GDFs toward the NHDF phenotype. Collectively, our preliminary investigation of the Gorlin phenotype has identified deficient ALDH1A1 expression associated with deficient ATM activation as a possible susceptibility factor that is consistent with the high incidence of spontaneous and radiation-induced carcinogenesis in these patients. The IncubATR technology exhibits sufficient sensitivity to detect phenotypic differences in live cells that may be relevant to radiation health effects.

    Full Text Available Introduction. Streptococcal toxic shock syndrome is now recognized as a toxin-mediated, multisystem illness. It is characterized by an early onset of shock with multiorgan failure and continues to be associated with high morbidity and mortality, caused by group A Streptococcus pyogenes. The symptoms for staphylococcal and streptococcal toxic shock syndrome are similar. Streptococcal toxic shock syndrome was not well described until 1993, when children who had suffered from varicella presented roughly 2-4 weeks later with a clinical syndrome highly suggestive of toxic shock syndrome. Characteristics, complications and therapy. It is characterized by a sudden onset of fever, chills, vomiting, diarrhea, muscle aches and rash. It can rapidly progress to severe and intractable hypotension and multisystem dysfunction. Almost every organ system can be involved. Complications of streptococcal toxic shock syndrome may include kidney failure, liver failure and even death. Crystalloids and inotropic agents are used to treat the hypovolemic shock aggressively, with close monitoring of the patient’s mean arterial pressure and central venous pressure. An immediate and aggressive management of hypovolemic shock is essential in streptococcal toxic shock syndrome. Targeted antibiotics are indicated; penicillin or a betalactam antibiotic is used for treating group A streptococci, and clindamycin has emerged as a key portion of the standard treatment.

    A centralizer assembly is disclosed that allows for the assembly to be deployed in-situ. The centralizer assembly includes flexible members that can be extended into the well bore in situ by the initiation of a gas generating device. The centralizer assembly can support a large load carrying capability compared to a traditional bow spring with little or no installation drag. Additionally, larger displacements can be produced to centralize an extremely deviated casing.

    2009-03-07

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

    Objective  To investigate the neuropathological changes of central nervous system in Guillain-Barré syndrom. Methods Brain, spinal cord and sciatic nerve were obtained from 22 cases of Guillain-Barré syndrome. Eight cases were examined by general autopsy, 14 cases were examined by limited autopsy. HE, KB, Bielschowsky, Weil and Sudan Ⅲ staining were carried out, the sections were observed by light microscopy. Results 1.Cerebral superficial veins congested, widening of the cortical sulci, narrowed gyri and mild cerebellar tonsillar hernia were present. 2. Majority of cerbral neurons presented an ischemic changes. Slightly loss of hippocampal pyramidal neurons were found. There was chromatolysis of motor neurons of brain stem. Lymphocytic infiltration around the small vessels occurred in the pons and medullary oblongata in 8 cases. Focal demyelination was noted in pons and frontal white matter in 2 cases. Loss of Purkinje cells and appearance of glial nodules were observed in molecular layer of cerebellum. 3. Swellin, central chromatolysis and eccentric nuclei of anterior horn cells appeared in 16 cases, which were pronounced in cervical and lumbal segment of spinal cord. Vaculated neuroplasma and lymphacytic infiltrition could be seen. 4. Segmental demyelination and lymphocytic infiltration were the main neuropathological changes observed in 20 cases. There were two other cases in which the axon were severely involved, which showed swelling and breakdown of axons and as well as axonal bulbs. Conclusions 1. Lymphocytic infiltration in brain stem and spinal cord were in continuousness of pathological changes of peripheral nerves. 2. Finding of glial nodules suggested that there was possibility of infection of neurotropic virus. 3. Occurence of focal demyelination in cerebrum and brain stem indicated that Guillain-Barré syndrome may have combined involvement of central and peripheral nervous system.%目的观察

    Catastrophic antiphospholipid syndrome is the most dangerous form of the antiphospholipid syndrome, which is characterized by rapid onset of thrombosis in small vessels of many organs and intravascular coagulation, thrombocytopenia and hemolytic anemia. The syndrome develops over a short period of time with acute multi-organ failure, including kidney, respiratory, cardiovascular, central nervous system and adrenal glands, often associated with disseminated thrombotic microangiopathy. The catastrophic antiphospholipid syndrome involves three or more systems, organs and/or tissues, the development of symptoms must occur within less than one week, it is necessary to confirm the histopathological vascular occlusion in at least one organ or tissue, and laboratory confirmation of the presence of antiphospholipid antibodies in the serum on two occasions over an interval of 12 weeks. This syndrome is characterized by a high mortality despite the use of optimal treatment. Early diagnosis and aggressive treatment of patients with catastrophic antiphospholipid syndrome is essential to save the life of these patients. In the last 10 years, the mortality in this disease decreased from 50% to 30% with simultaneous treatment with anticoagulants, corticosteroids, plasmapheresis and immunoglobulins.

  10. Hypereosinophilic syndromes

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

    Since two decades, sleep breathing disorders are more wisely recognized by the Belgian medical community. Among these, the Obstructive Sleep Apnea Syndrome (OSA) is the best known but its frontiers with others syndromes such as the Upper Airway Resistance Syndrome (UARS), the Central Sleep Apnea Syndrome (CSAS) or the Overlap Syndrome are still matter of discussion. Its causes are plurifactorial, and many recent publications draw the attention to its long term effects in the cardiovascular and neuropsychiatric fields. This article summarizes the present definitions and features associated with OSA, from clinical and neurophysiological perspectives, and the different consequences to which untreated or underdiagnosed patients are exposed.

    Congenital malformations of the nose can be associated with a variety of syndromes, including solitary median maxillary central incisor syndrome, CHARGE syndrome, Bosma syndrome, median cleft face syndrome, PHACES association, Bartsocas-Papas syndrome, Binder syndrome, duplication of the pituitary gland-plus syndrome and syndromic craniosynsotosis (e.g., Apert and Crouzon syndromes) among other craniofacial syndromes. Imaging with CT and MRI plays an important role in characterizing the nasal anomalies as well as the associated brain and cerebrovascular lesions, which can be explained by the intimate developmental relationship between the face and intracranial structures, as well as certain gene mutations. These conditions have characteristic imaging findings, which are reviewed in this article. (orig.)

    Tuberculosis (TB) has shown a resurgence in nonendemic populations in recent years and accounts for 8 million deaths annually in the world. Central nervous system involvement is one of the most serious forms of this infection, acting as a prominent cause of morbidity and mortality in developing countries. The rising number of cases in developed countries is mostly attributed to factors such as the pandemic of acquired immunodeficiency syndrome and increased migration in a globalized world. Mycobacterium TB is responsible for almost all cases of tubercular infection in the central nervous system. It can manifest in a variety of forms as tuberculous meningitis, tuberculoma, and tubercular abscess. Spinal infection may result in spondylitis, arachnoiditis, and/or focal intramedullary tuberculomas. Timely diagnosis of central nervous system TB is paramount for the early institution of appropriate therapy, because delayed treatment is associated with severe morbidity and mortality. It is therefore important that physicians and radiologists understand the characteristic patterns, distribution, and imaging manifestations of TB in the central nervous system. Magnetic resonance imaging is considered the imaging modality of choice for the study of patients with suspected TB. Advanced imaging techniques including magnetic resonance perfusion and diffusion tensor imaging may be of value in the objective assessment of therapy and to guide the physician in the modulation of therapy in these patients.

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

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

    The autoinflammatory syndromes include a group of inherited diseases that are characterized by 1) seemingly unprovoked episodes of systemic inflammations, 2) absence of high titer of autoantibody or auto-reactive T cell, and 3) inborn error of innate immunity. In this article, we will focus on the clinical features, the pathogenesis related the genetic defects, and the therapeutic strategies in the representative disorders including familial Mediterranean fever (FMF), TNF receptor associated periodic syndrome (TRAPS), cryopyrin-associated periodic syndrome (CAPS), hyper-IgD with periodic fever syndrome (HIDS), syndrome of pyogenic arthritis with pyoderma gangrenosum and acne (PAPA), and Blau syndrome. Recent advances in genetics and molecular biology have proceeded our understanding of the pathogenesis of autoinflammatory syndromes.

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

    Full Text Available The constellation of dyslipidemia (hypertriglyceridemia and low levels of high-density lipoprotein cholesterol, elevated blood pressure, impaired glucose tolerance, and central obesity is now classified as metabolic syndrome, also called syndrome X. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria for use in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general, they include a combination of multiple and metabolic risk factors. The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics, commonly manifest a prothrombotic state as well as and a proinflammatory state. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB, increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C. The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of atherosclerotic cardiovascular disease (ASCVD risk factors, that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to the components of the syndrome present as well as the other, non-metabolic syndrome risk factors in a particular person.

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

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

    The gut microbiome contributes approximately 2kg of the whole body weight, and recent studies suggest that gut microbiota has a profound effect on human metabolism, potentially contributing to several features of the metabolic syndrome. Metabolic syndrome is defined by a clustering of metabolic disorders that include central adiposity with visceral fat accumulation, dyslipidemia, insulin resistance, dysglycemia and non-optimal blood pressure levels. Metabolic syndrome is associated with an increased risk of cardiovascular diseases and type 2 diabetes. It is estimated that around 20-25 percent of the world's adult population has metabolic syndrome. In this manuscript, we have reviewed the existing data linking gut microbiome with metabolic syndrome. Existing evidence from studies both in animals and humans support a link between gut microbiome and various components of metabolic syndrome. Possible pathways include involvement with energy homeostasis and metabolic processes, modulation of inflammatory signaling pathways, interferences with the immune system, and interference with the renin-angiotensin system. Modification of gut microbiota via prebiotics, probiotics or other dietary interventions has provided evidence to support a possible beneficial effect of interventions targeting gut microbiota modulation to treat components or complications of metabolic syndrome.

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available Abstract Background Rett syndrome (RTT, a common cause of mental retardation in girls, is associated with mutations in the MECP2 gene. Most human cases of MECP2 mutation in girls result in classical or variant forms of RTT. When these same mutations occur in males, they often present as severe neonatal encephalopathy. However, some MECP2 mutations can also lead to diseases characterized as mental retardation syndromes, particularly in boys. One of these mutations, A140V, is a common, recurring missense mutation accounting for about 0.6% of all MeCP2 mutations and ranking 21st by frequency. It has been described in familial X-linked mental retardation (XLMR, PPM- X syndrome (Parkinsonism, Pyramidal signs, Macroorchidism, X-linked mental retardation and in other neuropsychiatric syndromes. Interestingly, this mutation has been reported to preserve the methyl-CpG binding function of the MeCP2 protein while compromising its ability to bind to the mental retardation associated protein ATRX. Results We report the construction and initial characterization of a mouse model expressing the A140V MeCP2 mutation. These initial descriptive studies in male hemizygous mice have revealed brain abnormalities seen in both RTT and mental retardation. The abnormalities found include increases in cell packing density in the brain and a significant reduction in the complexity of neuronal dendritic branching. In contrast to some MeCP2 mutation mouse models, the A140V mouse has an apparently normal lifespan and normal weight gain patterns with no obvious seizures, tremors, breathing difficulties or kyphosis. Conclusion We have identified various neurological abnormalities in this mouse model of Rett syndrome/X-linked mental retardation which may help to elucidate the manner in which MECP2 mutations cause neuronal changes resulting in mental retardation without the confounding effects of seizures, chronic hypoventilation, or other Rett syndrome associated symptoms.

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

  7. Neuroacanthocytosis Syndromes

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

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

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

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

    1975-12-01

    The sexual precocity of polyostotic fibrous dysplasia is occasionally accompanied by other endocrine disorders, but in only two previous instances has Cushing syndrome been reported. The history of a 6-month-old girl is presented, in whom this syndrome was complicated by congenital Cushings syndrome. Although endocrinopathies of polyostotic fibrous dysplasia have usually been ascribed to a central (hypothalamic) origin, the findings in this patient suggest autonomous hyperfunction of the peripheral endocrine glands, with the Cushing syndrome caused by hyperplastic nodules in the adrenal glands and the precocity by luteinized follicular cysts of the ovary.

    Full Text Available Fibromyalgia syndrome (FMS is a common chronic condition of widespread pain with causal mechanisms that are largely unknown. It is characterized by moderate to severe musculoskel - etal pain and allodynia, but its pathogenesis appears confined to the nociceptive structures of the central nervous system. From a pathogenetic point of view, indeed, no clear muscle pathology has been demonstrated in FMS (1, 2, while increasing evidence suggests a disturbance in pain perception that is genetically conditioned. In our review we will consider five “keypoints” that we think determine the origin and maintenance of the pain syndrome that we define as fibromyalgia...

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

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

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

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

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

    Full Text Available Toxic effects that occur after acute organophosphate poisoning (OP can manifest three phases, namely, acute cholinergic crisis, intermediate syndrome and delayed-type polyneuropathy. Clinical signs and symptoms of organophosphate poisoning depend on the accumulation of acetylcholine at the nerve junction. Organophosphate poisoning causes three main clinical findings; acute cholinergic crisis consisting of muscarinic, nicotinic and central nervous system symptoms, intermediate syndrome with recurrence of cholinergic symptoms or muscle weakness without fasciculation 24-96 hours after poisoning and delayed-type polyneuropathy that can usually occur several days or weeks after acute exposure to organic phosphorus compounds.

    Full Text Available Cohen syndrome is a rare genetic disease that is transmitted in an autosomal recessive pattern. It is characterized by obesity, hypotonia, mental retardation, microcephaly, typical craniofacial dysmorphism, large and prominent central incisors as well as thin, spindle-shaped fingers. The locus for Cohen syndrome has been located on chromosome 8q 22 (COH 1. Few cases have been reported since its description, it is clinically diagnosed through a proper delineation of the phenotype. The case of 14-year-old patient with this syndrome in whom a clinical diagnosis had not been established thus far is presented. An accurate delineation of the phenotype was achieved at this age and consequently, the correct diagnosis was reached, which is critical in order to provide better genetic counseling to the family.

  4. Pfeiffer syndrome

    Directory of Open Access Journals (Sweden)

    Fryns Jean-Pierre

    2006-06-01

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

    Rett syndrome is an increasingly recognized progressive disorder in females, commencing in infancy and characterized by autistic behavior, gait ataxia, stereotyped movements, seizures and generalized growth and mental retardation, possibly associated with disorders of central biogenic amine synthesis. The gene locus and pathogenesis of Rett syndrome are unknown. Autopsy studies in nine girls dying between 4 and 17 years, and sural nerve and muscle biopsies from two girls aged 3 and 17 years showed: (1) diffuse cortical atrophy/micrencephaly, with a decrease in brain weight by 12% to 34% of age-matched controls, apparently related to the duration of the disorder; (2) mild diffuse cortical atrophy with increased amounts of neuronal lipofuscin and occasional mild gliosis, but without signs of a storage disorder; (3) underpigmentation of the zona compacta nigrae, which showed fewer well-pigmented neurons for age and fewer melanin granules per neuron, while total numbers of nigral neurons and the substructure of neuromelanin were normal for age. No pathological changes were seen in other transmitter-specific brain stem nuclei; (4) immunoreactivity for tyrosine hydroxylase was slightly reduced in nigral and hypothalamic neurons, and the pituitary gland showed decreased immunoreaction for prolactin and growth hormone; (5) ultrastructurally, in frontal cortex and caudate nucleus, isolated abnormal neurites and reactive or degenerative axonal swellings were seen; the latter are possibly related to the nigral changes, suggesting some dysfunction of the dopaminergic nigrostriatal system, which is supported by neurochemical data; (6) preliminary biochemical studies revealed increased beta-endorphines in thalamus and cerebellum; (7) peripheral nerves demonstrated increase in small fibers without demyelination and increased numbers of neurofilaments in axons, suggesting distal axonopathy, while skeletal muscle showed alterations in the sarcoplasmic reticulum with circular

    2011-01-01

    Full Text Available Trigeminal trophic syndrome is a rare condition resulting from self-manipulation of the skin after a peripheral or central injury to the trigeminal system. The syndrome consists of a classic triad of anaesthesia, paraesthesia, and a secondary persistent or recurrent facial ulceration. We describe a 60 year-old woman who developed this syndrome as a sequel to the gasserian ganglion block for trigeminal neuralgia. She had also developed melasma within 1 year. A remarkable benefit was achieved by proper patient education and topical antibiotics which led to the healing of all ulcerations within 4 weeks. In the case reported here, the diagnosis of the trigeminal trophic syndrome was made primarily as a result of the physician′s experience with the syndrome previously.

    Even though autoimmune thyroiditis is considered as the most emblematic type of organ-specific autoimmune disorder of autoimmunity, autoimmune thyroid diseases can be associated with other autoimmune endocrine failures or non-endocrine diseases (namely vitiligo, pernicious anemia, myasthenia gravis, autoimmune gastritis, celiac disease, hepatitis). Thyroid disorders, which are the most frequent expression of adult polyendocrine syndrome type 2, occur concomitantly with or secondarily to insulinodependent diabetes, premature ovarian failure, Addison's disease (Schmidt syndrome, or Carpenter syndrome if associated with diabetes). Testicular failure and hypoparathyroidism are unusual. The disease is polygenic and multifactorial. Disorders of thyroid autoimmunity are, surprisingly, very rare in polyendocrine syndrome type 1 (or APECED) beginning during childhood. They are related to mutations of the AIRE gene that encodes for a transcriptional factor implicated in central and peripheral immune tolerance. Hypothyroidism can also be observed in the very rare IPEX and POEMS syndromes.

    Subarachnoid hemorrhage is the most common cause of cerebral salt wasting syndrome. There are few reports of this condition in infectious meningitis. We describe a patient with hyponatremia and bacterial meningitis. Hyponatremia rapidly improved after administration of sodium chloride. The purpose of this report is to alert clinicians to the fact that hyponatremic patients with central nervous system disease do not necessarily have a syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but may have cerebral salt wasting syndrome. By contrast with SIADH, the treatment requires saline administration.

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

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

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

  13. Compartment syndromes

    1989-01-01

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

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

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

  17. Eagle's Syndrome

    Pinheiro, Thaís Gonçalves

    2014-01-01

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

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

    Central hypersomnias include narcolepsy type 1, type 2 and idiopathic hypersomnia with daytime sleepiness excessive in the foreground of the clinical symptoms. Despite major advances in our understanding of the mechanisms of the narcolepsy type 1 with a low level of hypocretin-1 in cerebrospinal fluid, its current management is only symptomatic. The current management is also only symptomatic for type 2 narcolepsy and idiopathic hypersomnia with an unknown pathophysiology. Treatment options may vary from a single drug targeting several symptoms or several drugs treating a specific symptom. The treatment of daytime sleepiness is based on modafinil in first intention. Other psychostimulants such as methylphenidate, pitolisant and exceptionally dextro-amfetamine may be considered. In narcolepsy type 1, antidepressants such as inhibitors of the reuptake of serotonin and noradrenaline will be considered to improve cataplexy. Sodium oxybate is an effective treatment on sleepiness, cataplexy and bad night sleep in narcolepsy. The management for other symptoms or comorbidities should be considered it necessary such as hallucinations, sleep paralysis, the disturbed nighttime sleep, unpleasant dreams, parasomnias, depressive symptoms, overweight/obesity, cardiovascular disease and obstructive sleep apnea syndrome. Important therapeutic perspectives are to be expected concerning new psychostimulant and anticataplectiques, but mainly on immune-based therapies administered as early as possible after disease onset and on hypocretin replacement therapy for patients with severe symptoms.

    In patients with obstructive sleep apnea (OSA) syndrome and chronic respiratory insufficiency one of the options of treatment is bilevel positive airway pressure (BPAP) during sleep. The aim of the study was to find out what are the factors influencing the early results of BPAP treatment in such OSA patients. The study was carried out in 55 adult obese patients (mean body mass index 45 ± 7 kg/m(2)), severe OSA syndrome (mean apnea/hypopnea index 62 ± 19), and chronic respiratory insufficiency (mean PaCO(2) 54 ± 5.7 torr) who underwent polysomnography during BPAP treatment. In 31 patients (56%) the mean SaO(2) during sleep was <88% despite the optimal BPAP and oxygen titration: 83 ± 4% during NREM and 81 ± 7% during REM sleep vs. 91 ± 2% and 90 ± 3%, respectively, in the remaining 24 patients (p < 0.001). The patients with advanced hypoxemia during sleep and BPAP treatment had lower forced vital capacity (2.2 ± 0.9 vs. 2.7 ± 0.8 l, p < 0.05), lower diurnal PaO(2) (49 ± 8 vs. 54 ± 7 torr), higher diurnal PaCO(2) (57 ± 5 vs. 52 ± 5 torr, p < 0.01), and higher PaCO(2) during sleep (75 ± 13 vs. 59.5 ± 7.5 torr). In conclusion, in obese patients with severe OSA syndrome and chronic alveolar hypoventilation there is a risk of sleep hypoxemia during BPAP treatment, despite optimal pressure titration.

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

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

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

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

    Full Text Available INTRODUCTION Endogenous Cushing's syndrome is a clinical state resulting from prolonged, inappropriate exposure to excessive endogenous secretion of Cortisol and hence excess circulating free cortisol, characterized by loss of the normal feedback mechanisms of the hypothalamo-pituitary-adrenal axis and the normal circadian rhythm of cortisol secretion [2]. The etiology of Cushing's syndrome may be excessive ACTH secretion from the pituitary gland, ectopic ACTH secretion by nonpituitary tumor, or excessive autonomous secretion of cortisol from a hyperfunctioning adrenal adenoma or carcinoma. Other than this broad ACTH-dependent and ACTH-independent categories, the syndrome may be caused by ectopic CRH secretion, PPNAD, MAH, ectopic action of GIP or catecholamines, and other adrenel-dependent processes associated with adrenocortical hyperfunction. CASE REPORT A 31 year-old men with b-month history of hyperpigmentation, weight gain and proximal myopathy was refereed to Institute of Endocrinology for evaluation of hypercortisolism. At admission, patient had classic cushingoid habit with plethoric face, dermal and muscle atrophy, abdominal strie rubrae and centripetal obesity. The standard laboratory data showed hyperglycaemia and hypokaliemia with high potassium excretion level. The circadian rhythm of cortisol secretion was blunted, with moderately elevated ACTH level, and without cortisol suppression after low-dose and high-dose dexamethason suppression test. Urinary 5HIAA was elevated. Abdominal and sellar region magnetic resonance imaging was negative. CRH stimulation resulted in ACTH increase of 87% of basal, but without significant increase of cortisol level, only 7%. Thoracal CT scan revealed 14 mm mass in right apical pulmonary segment. A wedge resection of anterior segment of right upper lobe was performed. Microscopic evaluation showed tumor tissue consisting of solid areas of uniform, oval cells with eosinophilic cytoplasm and centrally

    Carpenter syndrome (acrocephalopolysyndactyly type II) is an autosomal recessive syndrome. The case we present was diagnosed prenatally at 20 weeks. Postmortem examination revealed severe central nervous system malformations. The central nervous system anomalies in this 23-week-old fetus merit emphasis, since these anomalies in such a young fetus may explain Carpenter syndrome cases, which do not improve in spite of early surgical intervention.

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

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

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

    1994-03-01

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

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

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

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

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

    Ocular histoplasmosis syndrome (OHS) is a chorioretinal disorder with a distinct fundus appearance that is commonly found in regions endemic for Histoplasma capsulatum. Choroidal neovascularization (CNV) secondary to OHS is considered one of the principal causes of central vision loss among young adults in endemic areas. Although there is no consensus regarding its pathogenesis, evidence points to Histoplasma capsulatum as the most probable etiology. Once considered an intractable hemorrhagic maculopathy, CNVs are now treatable. Extrafoveal CNVs are successfully treated with laser photocoagulation. Subfoveal and juxtafoveal CNVs are managed with anti-vascular endothelial growth factor therapy, photodynamic therapy, or a combination of both. Modern imaging technologies such as spectral-domain optical coherence tomography have improved our diagnostic abilities, making it easier to monitor disease activity and CNV regression. We review the epidemiology, pathogenesis, clinical manifestations, differential diagnosis, and current treatment of this disease.

    Full Text Available Takotsubo syndrome (TTS is an enigmatic disease with a multifactorial and still unresolved pathogenesis. Postulated mechanisms include catecholamine excess, coronary artery spasm, and microvascular dysfunction, however catecholamines seem to play a central role in the pathophysiology of TTS. In facts catecholamines have relevant effects on the vasculature and myocardium. Toxic direct effects of catecholamine on myocardium are mediated by multiple pathway including functional hypoxia, metabolic changes and changes in membrane permeability leading to various electrolytic imbalances. Recently report of familial cases has suggested a genetic component. Further research is required to help clarify the proposed hypotheses and to increase our understanding of the cardiovascular responses to acute stress and the pathophysiology underpinning TTS.

    Full Text Available Traumatic brain injury (TBI is on the rise, especially in today′s fast-paced world. TBI requires not only neurosurgical expertise but also neurointensivist involvement for a better outcome. Disturbances of sodium balance are common in patients with brain injury, as the central nervous system plays a major role in sodium regulation. Hyponatraemia, defined as serum sodium <135 meq/L is commonly seen and is especially deleterious as it can contribute to cerebral oedema in these patients. Syndrome of inappropriate antidiuretic hormone secretion (SIADH, is the most well-known cause of hyponatraemia in this subset of patients. Cerebral Salt Wasting Syndrome (CSWS, leading to renal sodium loss is an important cause of hyponatraemia in patients with TBI. Although incompletely studied, decreased renal sympathetic responses and cerebral natriuretic factors play a role in the pathogenesis of CSWS. Maintaining a positive sodium balance and adequate hydration can help in the treatment. It is important to differentiate between SIADH and CSWS when trying to ascertain a case for patients with acute brain injury, as the treatment of the two are diametrically opposite.

    Parental immigration has been suggested as a possible risk factor for autism spectrum disorders (ASD), but findings have been inconsistent. Very few studies have focused specifically on Asperger's syndrome. The aim of this study was to examine the association between maternal and paternal immigration and the diagnosis of Asperger's syndrome in offspring. The study was a nested case-control study based on a national birth cohort in Finland. Children born in 1987-2005 and diagnosed with Asperger's syndrome by the year 2007 were identified from the Finnish Hospital Discharge Register (N = 1,783). Four matched controls for each case were selected from the Finnish Medical Birth Register (N = 7,106). Information on maternal and paternal country of birth and mother tongue was collected from the Finnish Central Population Register. The study showed that children whose parents are both immigrants have a significantly lower likelihood of being diagnosed with Asperger's syndrome than those with two Finnish parents [adjusted odds ratio (aOR) 0.2, 95 % confidence interval (CI) 0.1-0.4]. No significant associations were found between having only one immigrant parent and the diagnosis of Asperger's syndrome. A regional analysis showed a significantly decreased likelihood of the diagnosis of Asperger's syndrome in children whose mother (aOR 0.1, 95 % CI 0.01-0.5) or father (aOR 0.2, 95 % CI 0.05-0.5) was born in Sub-Saharan Africa. The findings may help in identifying risk factors for different ASD subtypes. On the other hand, they might reflect service use of immigrant families in Finland.

    Among diseases that cause ichthyosis as one of the symptoms, there are some diseases that induce abnormalities in organs other than the skin. Of these, diseases with characteristic signs are regarded as syndromes. Although these syndromes are very rare, Netherton syndrome, Sjögren-Larsson syndrome, Conradi-Hünermann-Happle syndrome, Dorfman-Chanarin syndrome, ichthyosis follicularis, atrichia and photophobia (IFAP) syndrome, and Refsum syndrome have been described in texts as representative ones. It is important to know the molecular genetics and pathomechanisms in order to establish an effective therapy and beneficial genetic counseling including a prenatal diagnosis.

    Horner syndrome in children is rare. The frequency and spectrum of malignancy as the cause of Horner syndrome in children remains unclear. Also unclear is whether the imaging work-up should include the entire oculo-sympathetic pathway or should be more targeted. In addition, the value of cross-sectional angiographic imaging in Horner syndrome is uncertain. To review imaging pathology in a cohort of children with Horner syndrome at a major academic pediatric medical center. We reviewed a 22-year period of CT and MR imaging studies in children with a clinical diagnosis of Horner syndrome referred for imaging. We found 38 patients who fulfilled study criteria of Horner syndrome and 6/38 had relevant imaging findings: 2/6 etiologies were neoplastic (congenital neuroblastoma and central astrocytoma), 1/6 had a vascular abnormality (hypoplastic carotid artery), 1/6 had maldevelopment (Chiari I malformation), and 2/6 had inflammatory/traumatic etiology (viral cervical lymphadenopathy, post jugular vein cannulation). There was a similar number of congenital and acquired pathologies. The malignancies were found at any level of the oculosympathetic pathway. There are treatable causes, including malignancies, in children presenting with Horner syndrome, which justify imaging work-up of the entire oculosympathetic pathway, unless the lesion level can be determined clinically.

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

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

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

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

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

    2014-01-01

    The Space Radiation Standing Review Panel (from here on referred to as the SRP) was impressed with the strong research program presented by the scientists and staff associated with NASA's Space Radiation Program Element and National Space Biomedical Research Institute (NSBRI). The presentations given on-site and the reports of ongoing research that were provided in advance indicated the potential Risk of Acute and Late Central Nervous System Effects from Radiation Exposure (CNS) and were extensively discussed by the SRP. This new data leads the SRP to recommend that a higher priority should be placed on research designed to identify and understand these risks at the mechanistic level. To support this effort the SRP feels that a shift of emphasis from Acute Radiation Syndromes (ARS) and carcinogenesis to CNS-related endpoints is justified at this point. However, these research efforts need to focus on mechanisms, should follow pace with advances in the field of CNS in general and should consider the specific comments and suggestions made by the SRP as outlined below. The SRP further recommends that the Space Radiation Program Element continue with its efforts to fill the vacant positions (Element Scientist, CNS Risk Discipline Lead) as soon as possible. The SRP also strongly recommends that NASA should continue the NASA Space Radiation Summer School. In addition to these broad recommendations, there are specific comments/recommendations noted for each risk, described in detail below.

    Full Text Available Cessation of normal skin cleansing seen in geriatric or self-neglected patients can cause accumulation of keratinous crusts on the skin. In the extreme end of this spectrum is a condition known as Diogenes syndrome (DS. These patients may have psychiatric disorders like paranoid disorders, mood affection, or temporofrontal dementia. Subjects are mainly the elderly but few cases in younger age group of patients have also been reported. Lesions of DS are usually found over upper central chest, back, and groin. In the young, lesions are mainly found over scalp, face, or arms. Absence of normal skin cleaning causes keratin and dirty debris to accumulate and with time form a thick shell. These debris can be secondarily infected by bacteria, fungus, and so forth. These skin lesions are not usually seen in individual with proper hygiene. We report a case of Diogenes syndrome in a 34-year-old young male patient who had associated schizophrenia.

    2013-04-01

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

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

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

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

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

    Neuroimaging studies are of crucial relevance in defining the pathophysiology of restless legs syndrome (RLS). MRI studies showed no structural brain lesions and confirmed a central iron deficiency. Structural and functional studies showed an involvement of the thalamus, sensorimotor cortical areas, and cerebellum in RLS and assessed neurotransmission abnormalities in the dopaminergic and opiate systems. Finally, glutamatergic hyperactivity has been proposed as a cause of disrupted and shortened sleep in RLS. Differences among the results of the studies make it difficult to draw any definitive conclusions, thus, suggesting the need for future research.

  4. Adiponectin provides cardiovascular protection in metabolic syndrome.

    Okamoto, Yoshihisa

    2011-01-23

    Adipose tissue plays a central role in the pathogenesis of metabolic syndrome. Adiponectin (APN) is a bioactive adipocytokine secreted from adipocytes. Low plasma APN levels (hypoadiponectinemia) are observed among obese individuals and in those with related disorders such as diabetes, hypertension, and dyslipidemia. APN ameliorates such disorders. Hypoadiponectinemia is also associated with major cardiovascular diseases including atherosclerosis and cardiac hypertrophy. Accumulating evidence indicates that APN directly interacts with cardiovascular tissue and prevents cardiovascular pathology. Increasing plasma APN or enhancing APN signal transduction may be an ideal strategy to prevent and treat the cardiovascular diseases associated with metabolic syndrome. However, further studies are required to uncover the precise biological actions of APN.

  8. A Case of Classic Raymond Syndrome

    2012-01-01

    Full Text Available Classic Raymond syndrome consists of ipsilateral abducens impairment, contralateral central facial paresis, and contralateral hemiparesis. However, subsequent clinical observations argued on the presentation of facial involvement. To validate this entity, we present a case of classic Raymond syndrome with contralateral facial paresis. A 50 year-old man experienced acute onset of horizontal diplopia, left mouth drooling and left-sided weakness. Neurological examination showed he had right abducens nerve palsy, left-sided paresis of the lower part of the face and limbs, and left hyperreflexia. A brain MRI showed a subacute infarct in the right mid-pons. The findings were consistent with those of classic Raymond syndrome. To date, only a few cases of Raymond syndrome, commonly without facial involvement, have been reported. Our case is a validation of classic Raymond syndrome with contralateral facial paresis. We propose the concept of two types of Raymond syndrome: (1 the classic type, which may be produced by a lesion in the mid-pons involving the ipsilateral abducens fascicle and undecussated corticofacial and corticospinal fibers; and (2 the common type, which may be produced by a lesion involving the ipsilateral abducens fascicle and undecussated corticospinal fibers but sparing the corticofacial fibers.

    2011-06-01

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

    Full Text Available A serum sodium (Na value below 135 mEq/L is evaluated as hyponatremia. Hyponatremia is the most common electrolyte abnormality observed in hospitalized patients in particular. Hypovolemic hypoosmolar hyponatremia is the most frequent clinical table. One of the reasons of this is cerebral salt-wasting syndrome (CSWS. CSWS is a rare condition progressing with low plasma osmolality, urine osmolality above 100-150 mOsm/kg and urine- Na concentration above 20 mEq/L. In the blood and urine sample analysis performed upon sudden loss of consciousness on the 15th day of the intensive care unit follow-up of 79-year-old female patients due to falling from stairs, blood biochemistry Na value was 120 mEq/L, plasma osmolality was 250 mOsm/kg, urine Na value was 180 mEq/L, urine osmolality was 1200 mOsm/kg, urine diuresis was >3 mL/kg/hour. The central venous pressure was 2 mmHg. The patient, considered to be diagnosed with CSWS, was treated with 9% NaCl and 3% hypertonic saline solution. Her clinical course was improved on the 18th day. She died on the 81st day secondary to septicemia in the subsequent follow-up. In this article, it was aimed to report a patient with CSWS which progresses with low percentage in intensive care unit patients with head trauma, is frequently confused with inappropriate antidiuretic hormone syndrome and progresses mortally when not diagnosed distinctively well.

    Garavelli, Livia; Mainardi, Paola Cerruti

    2007-10-24

    Mowat-Wilson syndrome (MWS) is a multiple congenital anomaly syndrome characterized by a distinct facial phenotype (high forehead, frontal bossing, large eyebrows, medially flaring and sparse in the middle part, hypertelorism, deep set but large eyes, large and uplifted ear lobes, with a central depression, saddle nose with prominent rounded nasal tip, prominent columella, open mouth, with M-shaped upper lip, frequent smiling, and a prominent but narrow and triangular pointed chin), moderate-to-severe intellectual deficiency, epilepsy and variable congenital malformations including Hirschsprung disease (HSCR), genitourinary anomalies (in particular hypospadias in males), congenital heart defects, agenesis of the corpus callosum and eye anomalies. The prevalence of MWS is currently unknown, but 171 patients have been reported so far. It seems probable that MWS is under-diagnosed, particularly in patients without HSCR. MWS is caused by heterozygous mutations or deletions in the Zinc finger E-box-binding homeobox 2 gene, ZEB2, previously called ZFHX1B (SIP1). To date, over 100 deletions/mutations have been reported in patients with a typical phenotype; they are frequently whole gene deletions or truncating mutations, suggesting that haploinsufficiency is the main pathological mechanism. Studies of genotype-phenotype analysis show that facial gestalt and delayed psychomotor development are constant clinical features, while the frequent and severe congenital malformations are variable. In a small number of patients, unusual mutations can lead to an atypical phenotype. The facial phenotype is particularly important for the initial clinical diagnosis and provides the hallmark warranting ZEB2 mutational analysis, even in the absence of HSCR. The majority of MWS cases reported so far were sporadic, therefore the recurrence risk is low. Nevertheless, rare cases of sibling recurrence have been observed. Congenital malformations and seizures require precocious clinical

  13. Pain in Down's Syndrome

    Federica Mafrica

    2006-01-01

    Full Text Available Pain is a homeostatic mechanism that intervenes to protect the organism from harmful stimuli that could damage its integrity. It is made up of two components: the sensory-discriminative component, which identifies the provenance and characteristics of the type of pain; and the affective-motivational component, on which emotional reflexes, following the painful sensation, depend.There is a system for pain control at an encephalic and spinal level, principally made up of the periaqueductal grey matter, the periventricular area, the nucleus raphe magnus, and the pain-inhibition complex situated in the posterior horns of the spinal cord. Through the activation of these pain-control systems, the nervous system suppresses the afference of pain signals. Endogenous opioids represent another analgesic system.In the course of various studies on pain transmission in Down patients, the reduced tolerance of pain and the incapacity to give a qualitative and quantitative description emerged in a powerful way. All of these aspects cause difficulty in evaluating pain. This is linked to several learning difficulties. However, it cannot be excluded that in these anomalies of pain perception, both the anatomical and the neurotransmitter alteration, typical of this syndrome, may hold a certain importance.This fact may have important clinical repercussions that could affect the choice of therapeutic and rehabilitative schemes for treatment of pathologies in which pain is the dominant symptom, such as postoperative pain. It could influence research on analgesics that are more suitable for these patients, the evaluation of the depth of analgesia during surgical operation, and ultimately, absence of obvious pain manifestations. In conclusion, alterations of the central nervous system, neurotransmitters, pain transmission, and all related problems should be considered in the management of pain in patients with Down's syndrome, especially by algologists and

    Full Text Available Goldenhar syndrome (GHS is also known as Oculo-Auriculo-Vertebral (OAV syndrome or Branchial arch syndrome. Duane retraction syndrome (DRS is a congenital disorder of ocular motility characterized by limited abduction, adduction or both. It is unilateral in 80% of cases. The important and interesting part of this eight months old child is presence of GHS with DRS. She has bilateral invol-vement, which is seen in only 5-8% of GHS, as compared to high incidence of unilateral involve-ment. This child also had refractive error of + 6.00/ - 1.5 * 180. At four year of age her vision with glass was 6/9. Children with GHS and DRS should have early eye examination done to treat the problem of refractive error.

    Current long-duration missions to the International Space Station and future exploration-class missions beyond low-Earth orbit expose astronauts to increased risk of Visual Impairment and Intracranial Pressure (VIIP) syndrome. It has been hypothesized that the headward shift of cerebrospinal fluid (CSF) and blood in microgravity may cause significant elevation of intracranial pressure (ICP), which in turn may then induce VIIP syndrome through interaction with various biomechanical pathways. However, there is insufficient evidence to confirm this hypothesis. In this light, we are developing lumped-parameter models of fluid transport in the central nervous system (CNS) as a means to simulate the influence of microgravity on ICP. The CNS models will also be used in concert with the lumped parameter and finite element models of the eye described in the related IWS works submitted by Nelson et al., Feola et al. and Ethier et al.

    1993-01-01

    A clinical entity named "Bovine Paraplegic Syndrome" ("Síndrome Parapléjico de los Bovinos") has spread alarmingly, in the cattle growing areas of the central and eastern plains of Venezuela. Approximately four million cattle are bread in the area were the disease occurs. The mortality index due to the disease ranges 5 to 25% of the animals at risk, mostly cows, pregnant or lactating. The principal characteristic of the bovine paraplegic syndrome is decubitus, ventral or sternal, in animals that make vane efforts to stand when stimulated. The diagnosis is established ruling out, clinically and with laboratory findings, that the animals are suffering known diseases with similar symptoms such as paralytic rabies, botulism and blood parasites such Trypanosoma sp., Babesia sp., and Anaplasma sp.. Death occurs always, usually after few days, and to this date there is no known treatment able to save the sick cows. In this work, we describe results that suggest the presence of a toxin in the cattle suffering and prone to suffer the syndrome; it is a natural toxin produced by ruminal bacteria. In squid giant axons under voltage clamp conditions, this toxin is very specific to block sodium current during nerve electrical activity.

    This manuscript, developed by a group of chronic pain researchers and clinicians from around the world, aims to address the state of knowledge about fibromyalgia (FM) and identify ongoing challenges in the field of FM and other chronic pain syndromes that may be characterized by pain centralization/amplification/hypersensitivity. There have been many exciting developments in research studies of the pathophysiology and treatment of FM and related syndromes that have the potential to improve the recognition and management of patients with FM and other conditions with FM-like pain. However, much of the new information has not reached all clinicians, especially primary care clinicians, who have the greatest potential to use this new knowledge to positively impact their patients’ lives. Furthermore, there are persistent misconceptions about FM and a lack of consensus regarding the diagnosis and treatment of FM. This paper presents a framework for future global efforts to improve the understanding and treatment of FM and other associated chronic pain syndromes, disseminate research findings, identify ways to enhance advocacy for these patients, and improve global efforts to collaborate and reach consensus about key issues related to FM and chronic pain in general.

    2015-07-01

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

    Ivonne Marie Figueroa-Rivera

    2015-01-01

    Full Text Available Despite well-established antiemetic properties of marijuana, there has been increasing evidence of a paradoxical effect in the gastrointestinal tract and central nervous system, given rise to a new and underrecognized clinical entity called the Cannabinoid Hyperemesis Syndrome. Reported cases in the medical literature have established a series of patients exhibiting a classical triad of symptoms: cyclic vomiting, chronic marijuana use, and compulsive bathing. We present a case of a 29-year-old man whose clinical presentation strongly correlates with cannabinoid hyperemesis syndrome. Despite a diagnosis of exclusion, this syndrome should be considered plausible in the setting of a patient with recurrent intractable vomiting and a strong history of cannabis use as presented in this case.

    Galloway-Mowat syndrome (GMS) is an autosomal recessive disorder with a poor prognosis that was first defined as a triad of central nervous system involvement, hiatal hernia, and nephrotic syndrome. However, this syndrome is now known to have a heterogeneous clinical presentation. The nephrotic syndrome is steroid resistant and is responsible for the outcome. The combination of collapsing glomerulopathy and GMS is very rare. A 26-month-old boy presented with steroid-resistant nephrotic syndrome associated with neurologic findings, including microcephaly, psychomotor retardation, and nystagmus. Magnetic resonance imaging showed marked cerebral atrophy, optic atrophy, and hypomyelination. A renal biopsy was consistent with collapsing glomerulopathy. If collapsing glomerulopathy is associated with neurological abnormalities, especially with microcephaly, clinicians should consider GMS as a possible underlying cause. PMID:27403357

    Sneddon syndrome is a rare systemic vasculopathy affecting the skin as livedo racemosa and the central nervous system as stroke. A 31-year-old man with a history of livedo racemosa presented with a partial left third nerve palsy. Skin biopsy showed signs of endotheliitis with obliteration of dermal blood vessels due to intimal proliferation and fibrin thrombi consistent with Sneddon syndrome. The patient was treated with platelet antiaggregant therapy with complete resolution of his third nerve palsy. Clinicians should be aware of Sneddon syndrome because prompt diagnosis and treatment may prevent potential morbidity and mortality.

    Full Text Available Acute intraoperative superior vena cava (SVC syndrome is an exceedingly rare complication in the cardiac surgical population. We describe the case of a 71-year-old female undergoing multi-vessel coronary artery bypass grafting who developed acute intraoperative SVC syndrome following internal thoracic artery harvest retractor placement. Her symptoms included severe plethora, facial engorgement and scleral edema, which was associated with hypotension and severe elevation of central venous pressure. Transesophageal echocardiography was crucial in the diagnosis, management, and optimal retractor placement ensuring adequate SVC flow. Potential causes of intraoperative SVC syndrome are reviewed as well as management options.

    Some reports have shown the association between Moyamoya syndrome and autoimmune diseases. Herewith, we present a 3.5 yr old girl with Henoch- Schönleinpurpura (HSP) who was treated with steroids because of sever colicky abdominal pain. However, central nervous system manifestations such as headache, ataxia and vision impairment developed during 6 months of her outpatient follow-up. More evaluation using MRA revealed intracranial stenosis of internal carotid artery and arterial collaterals that were in favor of Moyamoya syndrome. To our knowledge, this is the first report of Moyamoya syndrome following henoch-schönleinpurpura. PMID:27843469

    Metabolic syndrome (MetS) is a cluster of metabolic traits associated with an increased risk of cardiovascular disease and type 2 diabetes mellitus. Central obesity and insulin resistance are thought to play key roles in the pathogenesis of the MetS. The MetS has a significant genetic component, and therefore linkage analysis, candidate gene approach, and genome-wide association (GWA) studies have been applied in the search of gene variants for the MetS. A few variants have been identified, located mostly in or near genes regulating lipid metabolism. GWA studies for the individual components of the MetS have reported several loci having pleiotropic effects on multiple MetS-related traits. Genetic studies have provided so far only limited evidence for a common genetic background of the MetS. Epigenetic factors (DNA methylation and histone modification) are likely to play important roles in the pathogenesis of the MetS, and they might mediate the effects of environmental exposures on the risk of the MetS. Further research is needed to clarify the role of genetic variation and epigenetic mechanisms in the development of the MetS.

    Fibromyalgia syndrome is mainly characterized by pain, fatigue, and sleep disruption. The etiology of fibromyalgia is still unclear: if central sensitization is considered to be the main mechanism involved, then many other factors, genetic, immunological, and hormonal, may play an important role. The diagnosis is typically clinical (there are no laboratory abnormalities) and the physician must concentrate on pain and on its features. Additional symptoms (e.g., Raynaud’s phenomenon, irritable ...

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.
