Hemifacial spasm (HFS) is a peripherally-induced movement disorder characterized by the involuntary, unilateral, intermittent, irregular, tonic or clonic contractions of muscles innervated by the ipsilateral facial nerve. Kindling-like hyperactivity of the facial nucleus induced by constant stimulation of compressing artery is considered as the predominant mechanism underlying the pathogenesis of HFS. As a treatment for HFS, microsurgical decompression and botulinum toxin injection have been shown to be highly successful. Anticonvulsant drugs relieve HFS in some patients; however, the use of such drugs is limited owing to their side effects, predominantly in elderly patients. We experienced two elderly HFS patients who exhibited a marked response to levetiracetam (LEV) without side effects. Although the exact underlying pharmacological mechanism remains unknown, we assume anti-kindling effect as one of the important pharmacological mechanism underlying the effect of LEV against HFS. Moreover, LEV is considered to be suitable for use in elderly patients because of its good tolerability. In addition, the lack of hepatic induction or inhibition makes it an easy and safe drug when used in addition to other anticonvulsants. Although the long-term benefit remains unknown, LEV may represent an alternative treatment for elderly HFS patients who are unable to undergo or decline surgical intervention and/or botulinum toxin injections or are intolerant to other anticonvulsants.

To evaluate the effect of hemifacial spasm (HFS) on intraocular pressure (IOP) measurement. Twenty-four consecutive patients with HFS and 25 age- and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and IOP measurements using Goldmann applanation tonometer (GAT) and noncontact tonometer (NCT). IOP measurements were performed before (during HFS) and 2 weeks after Botox injections in HFS patients and in healthy volunteers without Botox injections. There was no statistical difference between involved eye side and uninvolved eye side of HFS patients in measured central corneal thickness. Similarly, no difference was found between involved eye side of HFS patients and controls. There were no statistically significant differences comparing IOP values before treatment and levels measured at 2 weeks of Botox injections, either with GAT ( p = 0.33, 0.11) or NCT ( p = 0.80, 0.43) devices in the involved eyes and uninvolved eyes of patients with HFS, respectively. There were also no significant differences in these parameters (GAT ( p = 0.63) and NCT ( p = 0.54)) in controls. Contractions in facial muscles may not lead to significant increase in IOP in HFS patients. This result may help clinical decision making in the treatment of glaucoma patients with HFS. This trial is registered with NCT03390803.

Mood, anxiety, and other psychological symptoms are common in dystonic patients suffering from blepharospasm (BSP) and spasmodic torticollis (ST). Since sexual well-being is an important aspect of mental health, here, we investigated whether these patients may also experience a worsening of their sexual life. In particular, quality of sexual life was evaluated in patients suffering from BSP (N = 30), ST (N = 30), and in a control group of patient with Hemifacial spasm (HFS; N = 30), undergoing botulinum toxin type A therapy. A group of 30 age-matched healthy volunteers constituted an additional control group. Patients were evaluated just before the periodic injection of botulinum toxin. Sexual functioning was assessed using the Sexual Functioning Inventory, a reduced form of the Golombok Rust Inventory, previously employed in patients with Parkinson’s disease. Depression (Beck Depression Inventory) and anxiety (STAI-X1/X2) were also assessed. Results revealed that sexual functioning was significantly affected in patients with BSP, ST, and HFS with respect to healthy controls. Dystonic patients manifested more sexual dysfunction than patients with HFS. Overall, females had a poorer quality of sexual life than males and, among females, women with BSP were the most dysfunctional. Psychological symptoms were present in patients with dystonia, but not in patients with HFS. As discussed in the paper, several factors might be taken into account to explain worse quality of sexual life in patients with dystonia compared to patients with hemifacial spasm. Among them an important role might be played by the central origin of dystonia pathophysiology (i.e., altered activity of cortico-striato-thalamic-cortical circuits). Future investigations are necessary to further explore these preliminary findings, considering that this is the first time that sexual well-being is evaluated in patients with BSP, ST, and HFS, and comparable data are not available.

Resting-state functional magnetic resonance imaging (fMRI) has been used to detect the alterations of spontaneous neuronal activity in various neurological and neuropsychiatric diseases, but rarely in hemifacial spasm (HFS), a nervous system disorder. We used resting-state fMRI with regional homogeneity (ReHo) analysis to investigate changes in spontaneous brain activity of patients with HFS and to determine the relationship of these functional changes with clinical features. Thirty patients with HFS and 33 age-, sex-, and education-matched healthy controls were included in this study. Compared with controls, HFS patients had significantly decreased ReHo values in left middle frontal gyrus (MFG), left medial cingulate cortex (MCC), left lingual gyrus, right superior temporal gyrus (STG) and right precuneus; and increased ReHo values in left precentral gyrus, anterior cingulate cortex (ACC), right brainstem, and right cerebellum. Furthermore, the mean ReHo value in brainstem showed a positive correlation with the spasm severity (r = 0.404, p = 0.027), and the mean ReHo value in MFG was inversely related with spasm severity in HFS group (r = -0.398, p = 0.028). This study reveals that HFS is associated with abnormal spontaneous brain activity in brain regions most involved in motor control and blinking movement. The disturbances of spontaneous brain activity reflected by ReHo measurements may provide insights into the neurological pathophysiology of HFS.

Although Teflon is widely adopted for microvascular decompression (MVD) surgery, it has never been addressed for failure analysis. This study analyzed the reasons for failed MVDs with emphasis on the Teflon sponge. Among the 685 hemifacial spasm cases between 2010 and 2014, 31 were reoperated on within a week because of unsatisfactory outcome, which was focused on in this study. Intraoperative findings regarding Teflon inserts of these repeat MVDs were reviewed. Among the 38 without satisfactory outcomes, 31 underwent repeat MVDs, and they were all spasm free afterwards. Eventually, the final cure rate was 99.2%. It was found in the repeat MVDs that the failure was attributable to the Teflon insert in most of the cases (74.2%) directly or indirectly. It was caused by improper placement (47.8%), inappropriate size (34.8%) and unsuitable shape (17.4%) of the Teflon sponge. Although it is not difficult for an experienced neurosurgeon to discover a neurovascular conflict during the MVD process, the size, shape and location of the Teflon sponge should not be ignored. Basically, the Teflon insert is used to keep the offending artery away from the facial nerve root rather than to isolate it. Therefore, the ideal Teflon sponge should be just small enough to produce a neurovascular separation. © 2016 S. Karger AG, Basel.

We examined the relationship between hemifacial spasm (HFS; a form of cranio-cervical dystonia) and chronic primary headache, including tension-type headache (TTH). We also examined whether botulinum toxin A (BoNT/A) therapy for HFS ameliorates concomitant TTH. Fifty-one HFS patients receiving BoNT/A therapy were recruited. Patients' characteristics (including age, gender, chronic headache history, exercise habits, stiff neck, cervical spondylolysis history), stress factors, worsening/new onset of headache associated with HFS, and dose of BoNT/A were examined. We diagnosed headache types according to The International Classification of Headache Disorders, 3rd edition, beta. Numerical Rating Scale (NRS) and Headache Impact Test-6 (HIT-6) scores for headache severity were compared between the 6-week baseline before BoNT/A therapy and 6-week follow-up after BoNT/A therapy. Of 51 patients with HFS, 17 (33.3%) reported worsening or new onset of headache (especially TTH) associated with HFS (Group-S), and 34 were not aware of headache (Group-N). Twelve patients (70.6%) in group-S reported improvement of headache after BoNT/A therapy. NRS (from 7 [5-9] to 0 [0-5], p<0.01) and HIT-6 (from 55 [54-64] to 44 [36-52], p<0.001) scores were significantly improved after BoNT/A therapy. Logistic regression analysis revealed significant interaction between TTH associated with HFS and the presence of stress factors (odds ratio 43.11: 2.95-629.39, p<0.001) and history of chronic headache (odds ratio 28.53: 2.96-275.10, p<0.001). Primary headache, especially TTH, is associated with HFS. BoNT/A therapy for HFS may also be indirectly effective for treatment of TTH. Copyright © 2017 Elsevier Ltd. All rights reserved.

Vertebral artery pexy for microvascular decompression of the facial nerve in the treatment of hemifacial spasm.

Hemifacial spasm (HFS) is caused by arterial or venous compression of cranial nerve VII at its root exit zone. Traditionally, microvascular decompression of the facial nerve has been an effective treatment for posterior inferior and anterior inferior cerebellar artery as well as venous compression. The traditional technique involves Teflon felt or another construct to cushion the offending vessel from the facial nerve, or cautery and division of the offending vein. However, using this technique for severe vertebral artery (VA) compression can be ineffective and fraught with complications. The authors report the use of a new technique of VA pexy to the petrous or clival dura mater in patients with HFS attributed to a severely ectatic and tortuous VA, and detail the results in a series of patients. Six patients with HFS due to VA compression underwent a retrosigmoid craniotomy, combined with a far-lateral approach in some patients. On identification of the site of VA compression, the vessel was mobilized adequately for the decompression. Great care was taken to avoid kinking the perforating vessels arising from the VA. Two 8-0 nylon sutures were passed through to the wall of the VA and then through the clival or petrous dura, and then tied to alleviate compression on cranial nerve VII. Patients were followed for at least 1 year postoperatively (mean 2.7 years, range 1-4 years). All 6 patients had complete resolution of their HFS. Facial function was tested postoperatively, and was stable when compared with the preoperative baseline. Two of the 3 patients with preoperative tinnitus had resolution of this symptom after the procedure. Postoperative imaging demonstrated VA decompression of the facial nerve and no evidence of stroke in all patients. One patient suffered from hearing loss, another developed a postoperative transient unilateral vocal cord paralysis, and a third patient developed a pseudomeningocele that resolved with the placement of a lumbar drain

A previous study reported an increased prevalence of bruxism (25%) in patients with cranio-cervical dystonia (CCD) compared to normal controls (13%). CCD can affect the muscles of the head and neck. Besides the CCD affecting these muscles, hemifacial spasm (HFS) is a form of peripheral myoclonus due to a neurovascular conflict affecting the muscles of the face. The fact that they affect the same muscle regions could lead to other links in clinical manifestations such as bruxism, which is more common in patients with CCD than in the normal population. The aim was to study the prevalence of bruxism in patients with HFS. Patients with HFS were enrolled in the department of clinical neurophysiology (Bordeaux University Hospital) over a 6-month period. They were paired regarding age, the absence of neurological pathology or neuroleptics intake. To be included in the study, patients needed to have had unilateral involuntary facial muscle contractions affecting one hemiface. A hetero-questionnaire and a clinicial study were performed. The diagnostic criteria of bruxism included parafunction items such as grinding and clenching and at least one of the following clinical signs: abnormal tooth wear, temporomandibular joint (TMJ) pain, TMJ clicking, muscle hypertonia (masseter or temporal muscles). Additional epidemiological data were collected including age, sex, disease duration, stress, and sleep disorders. Stress symptoms inventory included symptoms like depression, strong heartbeat, dry mouth, anger, inability to concentrate, weakness, fatigability, insomnia, headache, and excessive sweating. The sleep disorder diagnosis included at least two of the symptoms described in the ICSD-3. All these criteria were recorded as either present (scored "1") or absent (scored "0"). The prevalence of bruxism in the two groups (normal and HFS) was not significantly different (p = 0.37). The rate was not significantly different between sleep and awake bruxism (p = 0.15) in both groups

Hemifacial spasm (HFS) associated with type 1 Chiari malformation is particularly uncommon and is limited to isolated case report. The aims of this study were to report the clinical correlates of patients who had simultaneously HFS and type 1 Chiari malformation and to present the outcome of these patients treated with microvascular decompression (MVD) surgery. We retrospectively evaluated 13 patients who had simultaneously HFS and type 1 Chiari malformation among 675 HFS patients. Clinical features and radiological findings were collected from each patient and analyzed. All these 13 patients were surgically treated with MVD through retro-mastoid microsurgical approach, and postoperative outcomes were evaluated. A review of literature about this association was also provided. In this study, the frequency of type 1 Chiari malformation in HFS patients was 1.9 %. The clinical profile of this series of patients did not differ from typical form of primary HFS. MVD achieved satisfactory results in 11 patients (85 %) in short- and long-term follow-up. There was no mortality or severe complication occurred postoperatively. Although rare, clinician should be aware of the association of HFS and type 1 Chiari malformation and consider MVD as an effective surgical management.

The aim of this study was to investigate the efficacy and side effects of botulinum toxin (BTX) in the treatment of hemifacial spasm (HFS). We also focused on the divergence between different injection techniques and commercial forms. We retrospectively evaluated 470 sessions of BTX injections administered to 68 patients with HFS. The initial time of improvement, duration and degree of improvement, and frequency and duration of adverse effects were analysed. Pretarsal and preseptal injections and Botox (Allergan, Irvine, CA, USA) and Dysport (Ipsen Biopharmaceuticals, Paris, France) brands were compared in terms of efficacy and side effects, accompanied by a review of papers which reported BTX treatment of HFS. An average of 34.5 units was used per patient. The first improvement was felt after 8 days and lasted for 14.8 weeks. Patients experienced a 73.7% improvement. In 79.7% of injections, no adverse effect was reported, in 4.9% erythema, ecchymosis, and swelling in the injection area, in 3.6% facial asymmetry, in 3.4% ptosis, in 3.2% diplopia, and in 2.3% difficulty of eye closure was detected. Patients reported 75% improvement on average after 314 sessions of pretarsal injections and 72.7% improvement after 156 sessions of preseptal injections (p=0.001). The efficacy and side effects of Botox and Dysport were similar. BTX is an effective and safe treatment option for HFS. No difference was determined between Botox and Dysport, and pretarsal injection is better than preseptal injection regarding the reported degree of improvement. Copyright © 2015 Elsevier Ltd.

2017-06-01

This study prospectively investigated the relationship between cerebellar retraction factors measured on preoperative magnetic resonance and the development of postoperative hearing loss and evaluated their potential role in predicting the possibility of hearing loss after microvascular decompression (MVD) for hemifacial spasm (HFS). The study included 110 patients clinically diagnosed with primary HFS who underwent MVD in our department. The cerebellar retraction factors were quantitatively measured on preoperative magnetic resonance. Associations of cerebellar retraction and other risk factors with postoperative hearing loss were analyzed. Eleven patients (10%) developed nonserviceable hearing loss after MVD. Compared with the group without hearing loss, the cerebellar retraction distance and depth of the group with hearing loss were significantly greater (P < 0.05). Multivariate logistic regression analysis showed that greater cerebellar retraction depth was significantly associated with the higher incidence of postoperative hearing loss (P < 0.05). The results in this study strongly suggested the correlation between the cerebellar retraction depth and the possibility of hearing loss after MVD for HFS. In addition, cerebellar retraction depth could be considered as a useful tool to predict the risk of post-MVD hearing loss. Copyright © 2017 Elsevier Inc. All rights reserved.

This prospective study quantitatively measured the cerebellar retraction factors, including retraction distance, depth and duration, and evaluated their potential relationship to the development of hearing loss after microvascular decompression (MVD) for hemifacial spasm (HFS). One hundred ten patients with primary HFS who underwent MVD in our department were included into this study. The cerebellar retraction factors were quantitatively measured on preoperative MR and timed during MVD. Associations of cerebellar retraction and other factors to postoperative hearing loss were analyzed. Eleven (10%) patients developed hearing loss after MVD. Compared with the group without hearing loss, the cerebellar retraction distance, depth and duration of the group with hearing loss were significantly greater (p < 0.05). Multivariate regression analysis showed that greater cerebellar retraction depth and longer retraction duration were significantly associated with a higher incidence of postoperative hearing impairment (p < 0.05). This study strongly suggested a correlation between the cerebellar retraction factors, especially retraction depth and duration, and possibility of hearing loss following MVD for HFS.

OBJECTIVE— To describe the long term efficacy and side effects of the treatment of hemifacial spasm with Dysport and to evaluate two different sites of injection to hopefully reduce side effects.
METHODS—This study was designed as a prospective descriptive study. Injections were made subcutaneously around the eye. Peak improvement was subjectively assessed by using a visual analogue scale and reported in percentages (0-100%). Duration of improvement was assessed subjectively and reported in months.
RESULTS—Of 175 cases, 17 were lost to follow up and were excluded. 855 treatments were injected in the remaining 158 patients with a median of 4 treatments. The response rate was 97%. Of 855 treatments, the adjusted mean peak and duration of improvement was 77.2 (95% confidence interval (95%CI) 74.7-79.4)% and 3.4 (95%CI 3.2-3.6) months respectively. In 158 patients (complete group), the long term results from the first to the 12th treatment showed that the mean peak improvement ranged from 72.70 to 80.10% and the duration of improvement was 2.60 to 3.71 months. It remained constant throughout (p=0.40, p=0.87 respectively). The most common side effect was ptosis. Of the 158 patients, 21 completed 12 treatments (subgroup). A separate analysis of this group disclosed a mean peak and duration of improvement from the first to 12th treatments ranging from 70.00 to 78.10% and 2.65 to 4.31 months respectively. Analysis of variance with repeated measures showed no significant variation of peak and duration of improvement over the first to the 12th treatments (p=0.38, p=0.38 respectively). Only 3% of the treatments were unsuccessful but responded to subsequent treatments. The incidence of ptosis was reduced from 27.17% to 9.68% by moving the injection site to the lateral part of orbital orbicularis oculi without any loss of efficacy. The yearly cost of Dysport is considerably less than Botox.
CONCLUSION—This study is the first to show, in detail, the long term

Hemifacial spasm (HFS) due to direct compression of the facial nerve by a dolichoectatic vertebrobasilar artery is rare. Vessels are often non-compliant and tethered by critical brainstem perforators. We set out to determine surgical strategies and outcomes for this challenging disease. All patients undergoing surgery for HFS secondary to vertebrobasilar dolichoectasia were reviewed. Hospital records, clinic notes and radiographic imaging were collected for outcome measures. Seventeen patients (eight males, nine females) were identified. Sixteen patients (94%) were treated with Teflon pledgets (DuPont, Wilmington, DE, USA) and one (6%) patient had a vascular sling placed around a severely diseased vertebral artery. All patients had significant reduction in symptoms and 82% of patients had complete resolution of symptoms (average follow-up: 41.4 months). One patient suffered persistent facial nerve paresis and swallowing difficulty. Two other patients suffered a 1 point decrease in the House-Brackmann facial nerve grading scale. Four patients (23%) required re-operation (infection, cerebrospinal fluid leak, and two patients with delayed recurrence of HFS). Of the latter, one patient required repositioning of a Teflon pledget and another patient underwent a sling decompression. There were no perioperative strokes or death. Excellent relief of symptoms with acceptable preoperative morbidity can be achieved using Teflon pledgets alone in most cases. In recalcitrant cases, sling transposition can be used to further augment the decompression. Careful attention must be paid to prevent vascular kinking and preserve brainstem perforators.

Blepharospasm and hemifacial spasm are debilitating conditions that significantly impact on patient quality of life. Cyclical treatment with botulinum toxin injections offers temporary relief, but the duration of treatment efficacy is variable. The standard model of patient care defines routine fixed-time based scheduled treatment cycles which may lead to unnecessarily frequent treatment for some patients and experience of distressing symptoms in others, if symptoms return before the scheduled follow-up period. A randomised controlled trial will compare a patient-initiated model of care, where patients determine botulinum toxin treatment timing, to the standard model of care in which care is scheduled by the clinical team. A sample of 266 patients with blepharospasm or hemifacial spasm will be recruited from Moorfields Eye Hospital (MEH), London. The trial will be accompanied by a mixed-methods evaluation of acceptability of the new service. Patients who meet eligibility criteria will be assessed at baseline and those in the intervention group will be provided with instructions on how to book their own treatment appointments. Patients in both groups will be followed up 3 and 9 months into the trial and all patients will be returned to usual care after 9 months to meet safety protocols. Primary outcome measures include disease severity (questionnaire), functional disability (questionnaire) and patient satisfaction with care (questionnaire). Secondary outcomes include disease-specific quality of life (questionnaire), mood (questionnaire), illness and treatment perceptions (questionnaire and semi-structured interviews), economic impact (questionnaire) and acceptability (questionnaire and semi-structured interviews). This trial will assess the effectiveness and cost-effectiveness of a patient-led care model for botulinum toxin therapy. If the new model is shown to be effective in reducing distress and disability in these populations and is found to be acceptable to

We report on vascular compression syndrome of the 12th cranial nerve (hypoglossal), an occurrence not previously reported, and demonstrate, through corresponding objective electrophysiological evidence, that microvascular decompression of the hypoglossal nerve root can cure hemilingual spasm. A 52-year-old man had lower face muscle twitching and tongue spasms, which worsened with talking, chewing, or emotional stress. Carbamazepine offered only temporary relief, and relief from injections of botulinum toxin was insignificant. He was referred for surgical treatment. High-resolution magnetic resonance imaging of his posterior fossa contents revealed no obvious evidence of any compressive vessel along the facial nerve, but a compressive vessel along the hypoglossal nerve was apparent. The presence of preoperative tongue spasms encouraged interoperative monitoring of tongue motor responses. The facial nerve exit zone was explored, but microsurgical inspection of the seventh/eighth cranial nerve complex did not reveal any compressive vessel. However, at the anterolateral aspect of the medulla oblongata, the hypoglossal nerve was clearly compressed and distorted laterally by a large tortuous vertebral artery. When the artery was mobilized away from the nerve, the abnormal late electromyographic response to transcranial electrical stimulation disappeared; immediately after shredded Teflon was interpositioned between the artery and the nerve, the abnormal spontaneous tongue fasciculation also disappeared. The patient has remained spasm free 6 months after surgery. Hemilingual spasm may be caused by vascular contact/compression along cranial nerve XII at the lower brainstem and belong to the same family of cranial nerve hyperactivity disorders as hemifacial spasm.

To address the feasibility and predictive value of multimodal image-based virtual reality in detecting and assessing features of neurovascular confliction (NVC), particularly regarding the detection of offending vessels, degree of compression exerted on the nerve root, in patients who underwent microvascular decompression for nonlesional trigeminal neuralgia and hemifacial spasm (HFS). This prospective study includes 42 consecutive patients who underwent microvascular decompression for classic primary trigeminal neuralgia or HFS. All patients underwent preoperative 1.5-T magnetic resonance imaging (MRI) with T2-weighted three-dimensional (3D) sampling perfection with application-optimized contrasts by using different flip angle evolutions, 3D time-of-flight magnetic resonance angiography, and 3D T1-weighted gadolinium-enhanced sequences in combination, whereas 2 patients underwent extra experimental preoperative 7.0-T MRI scans with the same imaging protocol. Multimodal MRIs were then coregistered with open-source software 3D Slicer, followed by 3D image reconstruction to generate virtual reality (VR) images for detection of possible NVC in the cerebellopontine angle. Evaluations were performed by 2 reviewers and compared with the intraoperative findings. For detection of NVC, multimodal image-based VR sensitivity was 97.6% (40/41) and specificity was 100% (1/1). Compared with the intraoperative findings, the κ coefficients for predicting the offending vessel and the degree of compression were >0.75 (P < 0.001). The 7.0-T scans have a clearer view of vessels in the cerebellopontine angle, which may have significant impact on detection of small-caliber offending vessels with relatively slow flow speed in cases of HFS. Multimodal image-based VR using 3D sampling perfection with application-optimized contrasts by using different flip angle evolutions in combination with 3D time-of-flight magnetic resonance angiography sequences proved to be reliable in detecting NVC

OBJECTIVE The aim of this study was to define a new protocol for intraoperative monitoring (IOM) of brainstem auditory evoked potentials (BAEPs) during microvascular decompression (MVD) surgery to treat hemifacial spasm (HFS) and to evaluate the usefulness of this new protocol to prevent hearing impairment. METHODS To define the optimal stimulation rate, estimate the number of trials to be averaged, and identify useful warning criteria in IOM of BAEPs, the authors performed a preliminary study of 13 patients with HFS in 2010. They increased the stimulation rate from 10.1 Hz/sec to 100.1 Hz/sec by 10-Hz increments, and they elevated the average time from 100 times to 1000 times by 100-unit increments at a fixed stimulus rate of 43.9 Hz. After defining the optimal stimulation rate and the number of trials that needed to be averaged for IOM of BAEPs, they also identified the useful warning criteria for this protocol for MVD surgery. From January to December 2013, 254 patients with HFS underwent MVD surgery following the new IOM of BAEPs protocol. Pure-tone audiometry and speech discrimination scoring were performed before surgery and 1 week after surgery. To evaluate the usefulness of the new protocol, the authors compared the incidence of postoperative hearing impairment with the results from the group that underwent MVD surgery prior to the new protocol. RESULTS Through a preliminary study, the authors confirmed that it was possible to obtain a reliable wave when using a stimulation rate of 43.9 Hz/sec and averaging 400 trials. Only a Wave V amplitude loss > 50% was useful as a warning criterion when using the new protocol. A reliable BAEP could be obtained in approximately 9.1 seconds. When the new protocol was used, 2 patients (0.8%) showed no recovery of Wave V amplitude loss > 50%, and only 1 of those 2 patients (0.39%) ultimately had postoperative hearing impairment. When compared with the outcomes in the pre-protocol group, hearing impairment incidence

PubMed Central

2017-01-01

Here we report a unique case of chronic occipital neuralgia caused by pathological vascular contact of the left greater occipital nerve. After 12 months of left-sided, unremitting occipital neuralgia, a hypesthesia and facial pain developed in the left hemiface. The decompression of the left greater occipital nerve from pathological contacts with the occipital artery resulted in immediate relief for hemifacial sensory change and facial pain, as well as chronic occipital neuralgia. Although referral of pain from the stimulation of occipital and cervical structures innervated by upper cervical nerves to the frontal head of V1 trigeminal distribution has been reported, the development of hemifacial sensory change associated with referred trigeminal pain from chronic occipital neuralgia is extremely rare. Chronic continuous and strong afferent input of occipital neuralgia caused by pathological vascular contact with the greater occipital nerve seemed to be associated with sensitization and hypersensitivity of the second-order neurons in the trigeminocervical complex, a population of neurons in the C2 dorsal horn characterized by receiving convergent input from dural and cervical structures.

Infantile spasms.

PubMed

Hrachovy, Richard A; Frost, James D

2013-01-01

Infantile spasms are a unique disorder of infancy and early childhood. The average age at onset of infantile spasms is 6 months and the average incidence of the disorder is approximately 0.31 per 1000 live births. Approximately one-quarter of patients will spontaneously stop having spasms within 1 year of onset. There are three main types of epileptic spasms: flexor, extensor, and mixed flexor-extensor. Spasms frequently occur in clusters and commonly occur upon arousal from sleep. The motor spasms are frequently confused with other normal and abnormal infant behaviors. Typically, the interictal EEG reveals hypsarrhythmia or one of its variants. A variety of ictal EEG patterns may be seen, the most common of which is a generalized slow-wave transient followed by an attenuation of the background activity in all regions. The primary treatment objective is to improve the EEG and stop the spasms as soon as possible and to avoid prolonged treatment durations with any form of therapy. Currently, there is no conclusive evidence that medical or surgical treatment of infantile spasms significantly alters long-term outcome. Although the pathophysiological mechanism underlying infantile spasms is unknown, several animal models of infantile spasms have been developed in recent years. Copyright © 2013 Elsevier B.V.

Arteriovenous malformations are congenital lesions that may evolve with time and manifest in a plethora of presentations. They can occur as torrential epistaxis when it extensively involves the facial region. Multi-imaging modalities are available to assist in characterizing the structure of the lesion as well as its location and extent. This complex disease requires a multidisciplinary team approach with preoperative embolization and surgery. We present a rare cause of life-threatening epistaxis in a gentleman with a longstanding orbital and hemifacial arteriovenous malformation and discuss the complexities involved in its management.

Objective To determine the frequency of mutations in CDKL5 in both male and female patients with infantile spasms or early onset epilepsy of unknown cause, and to consider whether the breadth of the reported phenotype would be extended by studying a different patient group. Methods Two groups of patients were investigated for CDKL5 mutations. Group 1 comprised 73 patients (57 female, 16 male) referred to Cardiff for CDKL5 analysis, of whom 49 (42 female, 7 male) had epileptic seizure onset in the first six months of life. Group 2 comprised 26 patients (11 female, 15 male) with infantile spasms previously recruited to a clinical trial, the UK Infantile Spasms Study. Where a likely pathogenic mutation was identified, further clinical data were reviewed. Results Seven likely pathogenic mutations were found among female patients from group 1 with epileptic seizure onset in the first six months of life, accounting for seven of the 42 in this group (17%). No mutations other than the already published mutation were found in female patients from group 2, or in any male patient from either study group. All patients with mutations had early signs of developmental delay and most had made little developmental progress. Further clinical information was available for six patients: autistic features and tactile hypersensitivity were common but only one had suggestive Rett‐like features. All had a severe epileptic seizure disorder, all but one of whom had myoclonic jerks. The EEG showed focal or generalised changes and in those with infantile spasms, hypsarrhythmia. Slow frequencies were seen frequently with a frontal or fronto‐temporal predominance and high amplitudes. Conclusions The spectrum of the epileptic seizure disorder, and associated EEG changes, in those with CDKL5 mutations is broader than previously reported. CDKL5 mutations are a significant cause of infantile spasms and early epileptic seizures in female patients, and of a later intractable seizure disorder

Coronary spasm is abnormal contraction of an epicardial coronary artery resulting in myocardial ischemia. Coronary spasm induces not only depressed myocardial contractility, but also incomplete myocardial relaxation, which leads to elevated ventricular filling pressure. We herein report the case of a 55-year-old woman who had repeated acute heart failure caused by coronary spasm. Acetylcholine provocation test with simultaneous right heart catheterization was useful for the diagnosis of elevated ventricular filling pressure as well as coronary artery spasm. We should add coronary spasm to a differential diagnosis for repeated acute heart failure.

Spasm of accommodation associated with closed head trauma.

PubMed

Chan, R V Paul; Trobe, Jonathan D

2002-03-01

Spasm of accommodation, creating pseudomyopia, is generally associated with miosis and excess convergence as part of spasm of the near reflex. It may also exist as an isolated entity, usually attributed to psychogenic causes. We present six cases of accommodative spasm associated with closed head injury. All patients were male, ranging in age between 16 and 37 years. The degree of pseudomyopia, defined as the difference between manifest and cycloplegic refraction, was 1.5 to 2 diopters. A 3-year trial of pharmacologically induced cycloplegia in one patient did not lead to reversal of the spasm when the cycloplegia was stopped. All patients required the manifest refraction to see clearly at distance. The pseudomyopia endured for at least 7 years following head trauma. This phenomenon may represent traumatic activation or disinhibition of putative brain stem accommodation centers in young individuals.

Facial asymmetry is one of the commonest facial anomalies, with reported incidence as high as 34%. Hemifacial microsomia (HFM) has an incidence of 1 in every 4000-5600 children and is one of the commonest causes of facial asymmetry. The standard treatment of HFM is orthognathic surgery by bilateral saggital split osteotomy (BSSO) or distraction osteogenesis (DO) of the mandible, both of which involve prolonged periods of occlusal adjustments by an orthodontist. Here, we present distraction of the mandible by means of a novel modified step osteotomy to correct the facial asymmetry in a case of hemifacial microsomia without disturbing the occlusion. This novel technique can prove to be a new tool in the maxillofacial surgeons armamentarium to treat facial asymmetry.

Acute hemifacial dystonia possibly induced by clebopride.

Dystonic reactions produce twisting and repetitive movements or abnormal posturing. Severe dystonic reactions have been shown to occur in concert with numerous medications. This report details the case of a patient who developed hemifacial dystonia as acute side reaction from administration of clebopride for dyspeptic prophylaxis. When the drug was immediately stopped, the dystonic posture disappeared completely within 2 weeks. The use of clebopride may be associated with not only a reversible or persistent parkinsonism syndrome but also hemifacial dystonia; therefore, attention must be drawn to this possible side effect.

Macrovascular Decompression of Facial Nerve With Anteromedial Transposition of a Dolichoectatic Vertebral Artery: 3-Dimensional Operative Video.

Most cranial nerve compression syndromes (ie, trigeminal neuralgia and hemifacial spasm) are caused by small arteries impinging on a nerve and are relieved by microvascular decompression. Rarely, cranial nerve compression syndromes can be caused by large artery impingement and can be relieved by macrovascular decompression. When present, this compression often occurs in association with degenerative atherosclerosis in the vertebral arteries (VA) and basilar artery. Conservative treatment is recommended for mild forms, but surgical transposition of the VA away from the root entry zone (REZ) can be considered. This video demonstrates macrovascular decompression of a dolichoectatic VA in a 74-yr-old female with refractory left hemifacial spasm. After obtaining IRB approval, patient consent was sought for the procedure. With the patient in three-quarter-prone position, a far-lateral craniotomy was performed. The dentate ligament was cut to free the VA, and the suprahypoglossal portion of the vagoaccessory triangle was widened. VA compressed the REZ of the facial nerve, but was mobilized anteromedially off the REZ. A muslin sling was wrapped around the VA and its tail brought down to the clival dura, which was punctured with a 19-gauge needle and enlarged with a dissector. The sling was pulled anteromedially to this puncture site and secured to the dura with an aneurysm clip, relieving the REZ of all compression. The patient tolerated the procedure with mild, transient hoarseness and her hemifacial spasm resolved completely. This case demonstrates the macrovascular decompression technique with anteromedial transposition of the vertebrobasilar artery, which can also be used for trigeminal neuralgia.

Hemifacial hyperhidrosis associated with ipsilateral/contralateral cervical disc herniation myelopathy. Functional considerations on how compression pattern determines the laterality

2014-01-01

Summary Sweating is an important mechanism for ensuring constant thermoregulation, but hyperhidrosis may be disturbing. We present five cases of hemifacial hyperhidrosis as a compensatory response to an/hypohidrosis caused by cervical disc herniation. All the patients complained of hemifacial hyperhidrosis, without anisocoria or blepharoptosis. Sweat function testing and thermography confirmed hyperhidrosis of hemifacial and adjacent areas. Neck MRI showed cervical disc herniation. Three of the patients had lateral compression with well-demarcated hypohidrosis below the hyperhidrosis on the same side as the cervical lesion. The rest had paramedian compression with poorly demarcated hyperhidrosis and hypohidrosis on the contralateral side. Although MRI showed no intraspinal pathological signal intensity, lateral dural compression might influence the circulation to the sudomotor pathway, and paramedian compression might influence the ipsilateral sulcal artery, which perfuses the sympathetic descending pathway and the intermediolateral nucleus. Sweat function testing and thermography should be performed to determine the focus of the hemifacial hyperhidrosis, and the myelopathy should be investigated on both sides. PMID:25014051

A comparison of three induction regimens using succinylcholine, vecuronium, or no muscle relaxant: impact on the intraoperative monitoring of the lateral spread response in hemifacial spasm surgery: study protocol for a randomised controlled trial

PubMed Central

2012-01-01

Background Surgical microvascular decompression (MVD) is the curative treatment for hemifacial spasm (HFS). Monitoring MVD by recording the lateral spread response (LSR) intraoperatively can predict a successful clinical outcome. However, the rate of the LSR varies between trials, and the reason for this variation is unclear. The aim of our trial is to evaluate the rate of the LSR after intubation following treatment with succinylcholine, vecuronium, or no muscle relaxant. Methods and design This trial is a prospective randomised controlled trial of 96 patients with HFS (ASA status I or II) undergoing MVD under general anaesthesia. Patients are randomised to receive succinylcholine, vecuronium, or no muscle relaxant before intubation. Intraoperative LSR will be recorded until dural opening. The primary outcome of this study is the rate of the LSR, and the secondary outcomes are post-intubation pharyngolaryngeal symptoms, the rate of difficult intubations, the rate of adverse haemodynamic events and the relationship between the measurement of LSR or not, and clinical success rates at 30 days after surgery. Discussion This study aims to evaluate the impact of muscle relaxants on the rate of the LSR, and the study may provide evidence supporting the use of muscle relaxants before intubation in patients with HFS undergoing MVD surgery. Trials registration http://www.chictr.org/ ChiCTR-TRC-11001504 Date of registration: 24 June, 2011. The date the first patient was randomised: 30 September, 2011. PMID:22958580

Intracranial epidermoid tumors are commonly found in the cerebellopontine angle where they usually present with either trigeminal neuralgia or hemifacial spasm. Radiosurgery for these tumors has rarely been reported. The purpose of this study is to assess the safety and clinical outcome of the treatment of cerebellopontine epidermoid tumors with gamma knife radiosurgery. This is a retrospective study involving 12 patients harboring cerebellopontine angle epidermoid tumors who underwent 15 sessions of gamma knife radiosurgery. Trigeminal pain was present in 8 patients and hemifacial spasm in 3 patients. All cases with trigeminal pain were receiving medication and still uncontrolled. One patient with hemifacial spasm was medically controlled before gamma knife and the other two were not. Two patients had undergone surgical resection prior to gamma knife treatment. The median prescription dose was 11 Gy (10-11 Gy). The tumor volumes ranged from 3.7 to 23.9 cc (median 10.5 cc). The median radiological follow up was 2 years (1-5 years). All tumors were controlled and one tumor shrank. The median clinical follow-up was 5 years. The trigeminal pain improved or disappeared in 5 patients, and of these, 4 cases stopped their medication and one decreased it. The hemifacial spasm resolved in 2 patients who were able to stop their medication. Facial palsy developed in 1 patient and improved with conservative treatment. Transient diplopia was also reported in 2 cases. Gamma knife radiosurgery provides good clinical control for cerebellopontine angle epidermoid tumors.

Management of cardiac arrest caused by coronary artery spasm: epinephrine/adrenaline versus nitrates.

PubMed

2009-01-01

Cardiopulmonary resuscitation guidelines imply the use of epinephrine/adrenaline during cardiopulmonary arrest. However, in cardiac arrest situations resulting from coronary artery spasm (CAS), the use of epinephrine/adrenaline could be deleterious. A 49-year-old patient underwent an emergency coronarography with an attempt to stent the coronary arteries. Radiologic imaging revealed a positive methylergonovine maleate (Methergine, Novartis Pharmaceuticals, East Hanover, NJ) test, with subocclusive CAS in several coronary vessels leading to electromechanical dissociation. Cardiopulmonary resuscitation was performed, and intracoronary boluses of isosorbide dinitrate were given to treat CAS. Epinephrine/adrenaline was not administered during resuscitation. Spontaneous circulation was obtained after cardioversion for ventricular fibrillation, and the patient progressively regained consciousness. Resuscitation guidelines do not specify the use of trinitrate derivatives in cardiac arrest situations caused by CAS. The pros and cons of the use of nitrates and epinephrine/adrenaline during cardiac arrest caused by CAS are analyzed in this case report.

Overview of the pharmacological spasm provocation test: Comparisons between acetylcholine and ergonovine.

2017-01-01

The spasm provocation tests of ergonovine and acetylcholine have been employed in the cardiac catheterization laboratory. Ergonovine acts through the serotogenic receptors, while acetylcholine acts through the muscarinic cholinergic receptors. Different mediators may have the potential to cause different coronary responses. However, there are few reports concerning the coronary response between ergonovine and acetylcholine in the same patients. Acetylcholine is supersensitive for females; spasm provoked by ergonovine is focal and proximal, whereas provoked spasm by acetylcholine is diffuse and distal. We should use both tests as supplementary in the clinic because ergonovine and acetylcholine have self-limitations to induce coronary spasms during daily life. The maximal pharmacological doses, administration methods, and the angiographical positive definition are remarkably different for each institution in the world. We recommend the pharmacological spasm provocation tests as Class I in the guidelines in patients with vasospastic angina throughout the world. Copyright © 2016 Japanese College of Cardiology.

Persistent accommodative spasm nine years after head trauma.

PubMed

Bohlmann, B J; France, T D

1987-09-01

Spasm of the near reflex is most often seen on a functional basis in young adults with underlying emotional problems. In particular, when convergence spasm is associated with miosis on attempted lateral gaze, a functional basis for the disorder should be suspected. Patients who experience spasm of the near reflex following trauma commonly follow a benign course with spontaneous resolution of their ocular complaints within 1-2 years. Accommodative spasm, manifested by pseudomyopia, or spasm of convergence, alone, or in combination with miosis, may be found as isolated signs of spasm of the near reflex. We report a patient who continues to demonstrate accommodative spasm 9 years after a motor vehicle accident.

[Spasm of accommodation].

Lindberg, Laura

2014-01-01

Spasm of accommodation refers to prolonged contraction of the ciliary muscle, most commonly causing pseudomyopia to varying degrees in both eyes by keeping the lens in a state of short sightedness. It may also be manifested as inability to allow the adaptation spasticity prevailing in the ciliary muscle relax without measurable myopia. As a rule, this is a functional ailment triggered by prolonged near work and stress. The most common symptoms include blurring of distance vision, varying visual acuity as well as pains in the orbital region and the head, progressing into a chronic state. Cycloplegic eye drops are used as the treatment.

2018-05-15

Although facial paralysis is a fundamental feature of hemifacial microsomia, the frequency and distribution of nerve abnormalities in patients with hemifacial microsomia remain unclear. In this study, the authors classified 1125 cases with microtia (including 339 patients with hemifacial microsomia and 786 with isolated microtia) according to Orbital Distortion Mandibular Hypoplasia Ear Anomaly Nerve Involvement Soft Tissue Dependency (OMENS) scheme. Then, the authors performed an independent analysis to describe the distribution feature of nerve abnormalities and reveal the possible relationships between facial paralysis and the other 4 fundamental features in the OMENS system. Results revealed that facial paralysis is present 23.9% of patients with hemifacial microsomia. The frontal-temporal branch is the most vulnerable branch in the total 1125 cases with microtia. The occurrence of facial paralysis is positively correlated with mandibular hypoplasia and soft tissue deficiency both in the total 1125 cases and the hemifacial microsomia patients. Orbital asymmetry is related to facial paralysis only in the total microtia cases, and ear deformity is related to facial paralysis only in hemifacial microsomia patients. No significant association was found between the severity of facial paralysis and any of the other 4 OMENS anomalies. These data suggest that the occurrence of facial paralysis may be associated with other OMENS abnormalities. The presence of serious mandibular hypoplasia or soft tissue deficiency should alert the clinician to a high possibility but not a high severity of facial paralysis.

APC conditional knock-out mouse is a model of infantile spasms with elevated neuronal β-catenin levels, neonatal spasms, and chronic seizures

Infantile spasms (IS) are a catastrophic childhood epilepsy syndrome characterized by flexion-extension spasms during infancy that progress to chronic seizures and cognitive deficits in later life. The molecular causes of IS are poorly defined. Genetic screens of individuals with IS have identified multiple risk genes, several of which are predicted to alter β-catenin pathways. However, evidence linking malfunction of β-catenin pathways and IS is lacking. Here, we show that conditional deletion in mice of the adenomatous polyposis coli gene (APC cKO), the major negative regulator of β-catenin, leads to excessive β-catenin levels and multiple salient features of human IS. Compared with wild-type littermates, neonatal APC cKO mice exhibit flexion-extension motor spasms and abnormal high-amplitude electroencephalographic discharges. Additionally, the frequency of excitatory postsynaptic currents is increased in layer V pyramidal cells, the major output neurons of the cerebral cortex. At adult ages, APC cKOs display spontaneous electroclinical seizures. These data provide the first evidence that malfunctions of APC/β-catenin pathways cause pathophysiological changes consistent with IS. Our findings demonstrate that the APC cKO is a new genetic model of IS, provide novel insights into molecular and functional alterations that can lead to IS, and suggest novel targets for therapeutic intervention.

2015-01-01

Esophageal diverticulum, a relatively rare condition, has been considered to be associated with motor abnormalities such as conditions that cause a lack of coordination between the distal esophagus and lower esophageal sphincter. We herein report a case of esophageal epiphrenic diverticulum associated with diffuse esophageal spasm. A 73-year-old woman presented with dysphagia and regurgitation. Imaging examinations revealed a right-sided esophageal diverticulum located about 10cm above the esophagogastric junction. High-resolution manometry revealed normal esophageal motility. However, 24-h pH monitoring revealed continuous acidity due to pooling of residue in the diverticulum. An esophageal epiphrenic diverticulum was diagnosed and resected thoracoscopically. Her dysphagia recurred 2 years later. High-resolution manometry revealed diffuse esophageal spasm. The diverticulum in the present case was considered to have been associated with diffuse esophageal spasm. The motility disorder was likely not identified at the first evaluation. In this case, the patient's symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Scientific skepticism and new discoveries: an analysis of a report of zinc/phytase supplementation and the efficacy of botulinum toxins in treating cosmetic facial rhytides, hemifacial spasm and benign essential blepharospasm.

2014-10-01

A recent paper in the Journal of Drugs in Dermatology by Koshy and colleagues (2012, 11( 4 ):507-512) report on "Effect of Dietary Zinc and Phytase Supplementation on Botulinum Toxin Treatments" and conclude by claiming the discovery of "a potentially meaningful role for zinc and/or phytase supplementation in increasing the degree and duration of botulinum toxin effect in the treatment of cosmetic facial rhytids, benign essential blepharospasm, and hemifacial spasm". The purpose of this paper is to examine these published claims for possible methodological and design errors and potential sources of bias. The authors evaluated the published results in comparison to the published literature on zinc deficiency, the role of phytase, prior reports of an effect of zinc on activity of botulinum toxin, issues of study design and execution and if the reported results of the study supported the study's conclusions. Multiple issues are present in the reported study, which appear to invalidate its conclusions. These areas include lack of direct evidence for the presence of clinical or subclinical zinc deficiency in the study population or for the level of phytate in the study population sufficient to interfere with zinc absorption in these subjects. Additionally, there is ambiguity as to the actual dose of zinc used as well as in the study design itself. Also there is a failure of the study through the "unmasking" of the crossover design. There is potential financial conflict of interest in the study execution that may have biased the reported results. Finally there is inadequate data presented to evaluate the claims made of a "new discovery" as to the three disease entities reported on and the various botulinum toxins used in each of the three treatment arms of the study. Based on this evaluation, it appears that a high level of clinical and scientific skepticism is warranted concerning any claim of a beneficial effect of zinc and phytase supplementation on the efficacy or

The Changes in Corneal Astigmatism after Botulinum Toxin-A Injection in Patients with Blepharospasm

2006-01-01

To determine if the involuntary contractions of eyelids may have any effects on the development of corneal astigmatism, we performed this prospective study which includes 19 patients with either essential blepharospasm or hemifacial spasm. In hemifacial spasm, the degree of corneal astigmatism was evaluated between two eyes. Then the topographic changes were checked using vector analysis technique before and after passively opening the eyelids. They were also measured before and at 1 and 6 months after the injection of Botulinum toxin. Resultantly, 20 eyes had the with-the-rule (group1) and 9 eyes against-the-rule (group2) astigmatism. In hemifacial spasm, significantly more astigmatism was found at spastic eyes. The corneal topographic changes after passively opening the eyelids showed 10 eyes with the astigmatic shift to the with-the-rule, while the remaining 19 to the against-the-rule. At 1 month after injection of Botulinum toxin, group 1 showed reduced average corneal astigmatism, whereas group 2 showed increased astigmatism. The astigmatic change vector showed significantly more against-the-rule. In the contrary, 6 months after treatment, corneal astigmatism again increased in group 1 and decreased in group 2. So they took on the appearance of pretreatment astigmatic status eventually. Conclusively eyelids may play an important role in corneal curvature. PMID:16479079

Hemifacial microsomia (HFM) is a birth defect involving craniofacial structures derived from the first and second branchial arches. Although it is a relatively uncommon malformation, it is the second most common craniofacial birth defect after cleft lip and palate (CL/P). This is a case report about the successful orthodontic treatment of a patient with mild hemifacial microsomia (HFM), using a non-surgical orthopedic and orthodontic treatment approach. The aim of this approach was to make the best noninvasive modality to treat HFM. A 7-year-old boy with a mild HFM presented with a convex profile and slight chin deviation. Orthopedic treatment performed using a hybrid functional and high pulls headgear. Treatment continued by fixed orthodontic straight wire appliance to achieve perfect occlusion. Excellent esthetic and functional results achieved; total treatment duration was about 72 months.

Bimatoprost is a prostaglandin analogue used topically in the treatment of glaucoma. Commonly known side effects include eyelash growth, iris pigmentation and conjunctival hyperemia. While pseudomyopia is reported to be caused by parasympathomimetics, such an effect precipitated by bimatoprost has not yet been reported. We report a case demonstrating pseudomyopia and accommodative spasm caused after starting bimatoprost 0.03% in a young patient with glaucoma. PMID:26598527

Serotonin, atherosclerosis, and collateral vessel spasm

NASA Technical Reports Server (NTRS)

Hollenberg, N.

1988-01-01

Studies on animal models demonstrate that platelet products contribute to vascular spasm in ischemic syndromes and that this is reversible with administration of ketanserin and thromboxane synthesis inhibitors. Laboratory animals (dogs, rabbits, and rats) that had femoral artery ligations exhibited supersensitivity to serotonin within days in their collateral blood vessels. This supersensitivity lasted at least 6 months. The response to serotonin was reversed by ketanserin, but not by 5HT-1 antagonists. Supersensitivity does not extend to norepinephrine, and alpha blockers do not influence the response to serotonin. It appears that platelet activation by endothelial injury contributes to ischemia through blood vessel occlusion and vascular spasm. When platelet activation occurs in vivo, blood vessel occlusion and vascular spasm are reversible in part by using ketanserin or agents that block thromboxane synthesis or its action. Combining both classes of agents reverses spasm completely. These findings support existing evidence that platelet products contribute to vascular disease, and provide an approach to improved management with currently available pharmacologic agents.

To evaluate initial magnetic resonance imaging (MRI) abnormalities in infantile spasms, correlate them to clinical characteristics, and describe repeat imaging findings. A retrospective review of infantile spasm patients was conducted, classifying abnormal MRI into developmental, acquired, and nonspecific subgroups. MRIs were abnormal in 52 of 71 infantile spasm patients (23 developmental, 23 acquired, and 6 nonspecific) with no correlation to the clinical infantile spasm characteristics. Both developmental and acquired subgroups exhibited cortical gray and/or white matter abnormalities. Additional abnormalities of deep gray structures, brain stem, callosum, and volume loss occurred in the structural acquired subgroup. Repeat MRI showed better definition of the extent of existing malformations. In structural infantile spasms, developmental/acquired subgroups showed differences in pattern of MRI abnormalities but did not correlate with clinical characteristics.

1992-12-01

A 72-year-old male underwent radical operation for cancer of the tongue. Anesthesia was maintained with the combination of enflurane-N2O-vecuronium and cervical epidural block. Five minutes after the cessation of the longstanding operation, VT and circulatory collapse occurred. After administration of lidocaine and ephedrine, VPC and ST elevation were noted, followed by VT and Vf. Cardioversion successfully restored sinus rhythm with no ST change, suggesting an episode of coronary artery spasm. The possible inducing factors in this case were hypotension and acute imbalance in autonomic nervous systems caused by hypovolemia, hypothermia, insufficient anesthetic depth, loss of surgical stress, neostigmine and epidural block. The authors reviewed case reports on coronary spasm, especially looking for possible inducing factors of coronary artery spasm during anesthesia.

The use of mandibular body distraction in hemifacial microsomia

Sakamoto, Yoshiaki; Nakajima, Hideo; Ogata, Hisao; Kishi, Kazuo

2013-01-01

Objective: The goals of treatment for hemifacial microsomia include horizontalization of occlusal plane and acquisition of facial symmetry. Although horizontalization of occlusal plane can be easily achieved, facial symmetry, particularly in relation to mandibular contour, can be difficult to attain. Soft tissue is generally reconstructed to correct facial asymmetry, and no studies have described correction of facial asymmetry through skeletal reconstruction. Case: A 12-year-old girl presented with grade IIb right-sided hemifacial microsomia. She was treated using Nakajima's angle-variable internal distraction (NAVID) system for mandibular body distraction. Results: Following treatment, appropriate facial symmetry was achieved, and the patient was extremely satisfied with the results. Conclusions: Thus, we successfully treated the present patient by our novel method involving distraction osteogenesis. This method was effective and useful for several reasons including; the changes were not accompanied by postoperative tissue absorption, donor sites were not involved, and the treatment outcome could be reevaluated by adjusting distraction while the patient's appearance was being remodeled.

We characterized the clinico-neurophysiological features of epileptic spasms, particularly focusing on high-voltage slow waves during ictal EEG. We studied 22 patients with epileptic spasms recorded during digital video-scalp EEG, including five individuals who still had persistent spasms after callosotomy. We analysed the duration, amplitude, latency to onset of electromyographic bursts, and distribution of the highest positive and negative peaks of slow waves in 352 spasms. High-voltage positive slow waves preceded the identifiable muscle contractions of spasms. The mean duration of these positive waves was 569±228 m, and the mean latency to electromyographic onset was 182±127 m. These parameters varied markedly even within a patient. The highest peak of the positive component was distributed in variable regions, which was not consistent with the location of lesions on MRI. The peak of the negative component following the positivity was distributed in the neighbouring or opposite areas of the positive peak distribution. No changes were evident in the pre- or post-surgical distributions of the positive peak, or in the interhemispheric delay between both hemispheres, in individuals with callosotomy. Our data imply that ictal positive slow waves are the most common EEG changes during spasms associated with a massive motor component. Plausible explanations for these widespread positive slow waves include the notion that EEG changes possibly reflect involvement of both cortical and subcortical structures.

Infantile spasms are the typical seizures of West syndrome, an infantile epileptic encephalopathy with poor outcomes. There is an increasing need to identify more effective and better tolerated treatments for infantile spasms. We have optimized the rat model of infantile spasms due to structural etiology, the multiple-hit rat model, for therapy discovery. Here, we test three compounds administered after spasms induction in the multiple hit model for efficacy and tolerability. Specifically, postnatal day 3 (PN3) male Sprague-Dawley rats were induced by right intracerebral injections of doxorubicin and lipopolysaccharide. On PN5 p-chlorophenylalanine was given intraperitoneally (i.p.). Daily monitoring of weights and developmental milestones was done and rats were intermittently video monitored. A blinded, randomized, vehicle-controlled study design was followed. The caspase 1 inhibitor VX-765 (50-200 mg/kg i.p.) and the GABA B receptor inhibitor CGP35348 (12.5-100 mg/kg i.p.) each was administered in different cohorts as single intraperitoneal injections on PN4, using a dose- and time-response design with intermittent monitoring till PN5. 17β-estradiol (40 ng/g/day subcutaneously) was given daily between PN3-10 and intermittent monitoring was done till PN12. None of the treatments demonstrated acute or delayed effects on spasms, yet all were well tolerated. We discuss the implications for therapy discovery and challenges of replication trials.

Objective: To assess the presence of DEPDC5 mutations in a cohort of patients with epileptic spasms. Methods: We performed DEPDC5 resequencing in 130 patients with spasms, segregation analysis of variants of interest, and detailed clinical assessment of patients with possibly and likely pathogenic variants. Results: We identified 3 patients with variants in DEPDC5 in the cohort of 130 patients with spasms. We also describe 3 additional patients with DEPDC5 alterations and epileptic spasms: 2 from a previously described family and a third ascertained by clinical testing. Overall, we describe 6 patients from 5 families with spasms and DEPDC5 variants; 2 arose de novo and 3 were familial. Two individuals had focal cortical dysplasia. Clinical outcome was highly variable. Conclusions: While recent molecular findings in epileptic spasms emphasize the contribution of de novo mutations, we highlight the relevance of inherited mutations in the setting of a family history of focal epilepsies. We also illustrate the utility of clinical diagnostic testing and detailed phenotypic evaluation in characterizing the constellation of phenotypes associated with DEPDC5 alterations. We expand this phenotypic spectrum to include epileptic spasms, aligning DEPDC5 epilepsies more with the recognized features of other mTORopathies. PMID:27066554

A 38-year old female with diplopia and esotropia, with limitation of ocular abduction in both eyes, with full abduction after doll's head rotation also being observed. She was diagnosed with spasm of the near reflex. Treatment with injections of botulinum toxin in both medial rectus has temporally resolved the convergence spasm. Near reflex spasm is characterized as miosis, pseudomyopia, and convergent strabismus that lead to diplopia, blurred vision, headache, and variable, progressive, and intermittent esotropia. As the spasm worsens there will be limited ocular versions and ductions simulating a sixth nerve palsy. Botulinum toxin may be effective in some cases.

2013-05-01

Painful tic convulsif is referred to as the concurrent trigeminal neuralgia and hemifacial spasm. However, painful tic convulsif after ipsilateral Bell palsy has never been reported before. We report a case of a 77-year-old woman with coexistent trigeminal neuralgia and hemifacial spasm who had experienced Bell palsy half a year ago. The patient underwent microvascular decompression. Intraoperatively, the vertebrobasilar artery was found to deviate to the symptomatic side and a severe adhesion was observed in the cerebellopontine angle. Meanwhile, an ectatic anterior inferior cerebellar artery and 2 branches of the superior cerebellar artery were identified to compress the caudal root entry zone (REZ) of the VII nerve and the rostroventral cisternal portion of the V nerve, respectively. Postoperatively, the symptoms of spasm ceased immediately and the pain disappeared within 3 months. In this article, the pathogenesis of the patient's illness was discussed and it was assumed that the adhesions developed from inflammatory reactions after Bell palsy and the anatomic features of the patient were the factors that generated the disorder. Microvascular decompression surgery is the suggested treatment of the disease, and the dissection should be started from the caudal cranial nerves while performing the operation.

Angiographic studies have shown that coronary artery spasm can be induced with ergonovine maleate. Coronary artery spasm induced by ergonovine maleate in these studies was nearly always accompanied by chest pain and electrocardiographic changes of myocardial ischemia. This report demonstrates that coronary artery spasm induced by ergonovine maleate may be diagnosed by angiography in the absence of these signs or symptoms.

The purpose of this study was to assess YouTube videos for their efficacy as a patient resource for infantile spasms. Videos were searched using the terms infantile spasm, spasm, epileptic spasm, and West syndrome. The top 25 videos under each term were selected according to set criteria. Technical quality, diagnosis of infantile spasms, and suitability as a teaching resource were assessed by 2 neurologists using the Medical Video Rating Scale. There were 5858 videos found. Of the 100 top videos, 46% did not meet selection criteria. Mean rating for technical quality was 4.0 of 5 for rater 1 and 3.9 of 5 for rater 2. Raters found 60% and 64% of videos to accurately portray infantile spasms, respectively, with significant agreement (Cohen κ coefficient = 0.75, P < .001). Ten videos were considered excellent examples (grading of 5 of 5) by at least 1 rater. YouTube may be used as an excellent patient resource for infantile spasms if guided search practices are followed.

Botulinum neurotoxin type A is a well-established treatment for a number of conditions involving muscle hyperactivity. Dysport (Ipsen Ltd, Wrexham, United Kingdom) is a botulinum neurotoxin type A preparation that has been available for a number of therapeutic uses for over 20 years in the European Union (EU). This survey was part of the EU botulinum toxin risk management plan to identify potential educational needs of injectors by collecting data on their routine practice administration of Dysport and their awareness of potential adverse events (AEs) that are included in the current product labeling. Dysport-experienced injectors in 5 EU countries were surveyed via telephone about their experience of Dysport in patients with cervical dystonia, adult upper and lower limb spasticity, pediatric cerebral palsy, and blepharospasm/hemifacial spasm. The reconstitution dilution volume most often used was 2.5 mL per 500 U for all indications. The mean total dose ranged from 387 to 530 U for cervical dystonia, 508 to 773 U for upper limb spasticity, 600 to 832 U for lower limb spasticity, 375 to 700 U for pediatric cerebral palsy, and 54 to 213 U for blepharospasm/hemifacial spasm. The potential AEs most commonly mentioned by surveyed physicians were dysphagia for cervical dystonia, arm muscle weakness for upper limb spasticity, leg muscle weakness for lower limb spasticity, and pediatric cerebral palsy and ptosis for blepharospasm/hemifacial spasm. The results indicate that product-labeling recommendations are generally applied in clinical practice and that there is a good familiarity with potential AEs based on clinical condition. Nevertheless, the survey shows that experienced injectors do sometimes deviate from the manufacturers labeling recommendations, highlighting the importance of ongoing education.

We aim to illustrate the applications of 3-dimensional (3-D) photogrammetry for surgical planning and longitudinal assessment of the volumetric changes in hemifacial microsomia. A 3-D photogrammetric system was employed for planning soft tissue expansion and transplantation of a vascularized scapular flap for a patient with hemifacial microsomia. The facial deficiency was calculated by superimposing a mirror of the normal side on the preoperative image. Postsurgical volumetric changes were monitored by serial superimposition of 3-D images. A total of 31 cm(3) of tissue expansion was achieved within a period of 4 weeks. A scapular free flap measuring 8 cm × 5 cm was transplanted to augment the facial deficiency. Postsurgical shrinkage of the flap was observed mainly in the first 3 months and it was minimal thereafter. 3-D photogrammetry can be used as a noninvasive objective tool for assessing facial deformity, planning, and postoperative follow-up of surgical correction of facial asymmetry.

Vigabatrin therapy implicates neocortical high frequency oscillations in an animal model of infantile spasms.

Abnormal high frequency oscillations (HFOs) in EEG recordings are thought to be reflections of mechanisms responsible for focal seizure generation in the temporal lobe and neocortex. HFOs have also been recorded in patients and animal models of infantile spasms. If HFOs are important contributors to infantile spasms then anticonvulsant drugs that suppress these seizures should decrease the occurrence of HFOs. In experiments reported here, we used long-term video/EEG recordings with digital sampling rates capable of capturing HFOs. We tested the effectiveness of vigabatrin (VGB) in the TTX animal model of infantile spasms. VGB was found to be quite effective in suppressing spasms. In 3 of 5 animals, spasms ceased after a daily two week treatment. In the other 2 rats, spasm frequency dramatically decreased but gradually increased following treatment cessation. In all animals, hypsarrhythmia was abolished by the last treatment day. As VGB suppressed the frequency of spasms, there was a decrease in the intensity of the behavioral spasms and the duration of the ictal EEG event. Analysis showed that there was a burst of high frequency activity at ictal onset, followed by a later burst of HFOs. VGB was found to selectively suppress the late HFOs of ictal complexes. VGB also suppressed abnormal HFOs recorded during the interictal periods. Thus VGB was found to be effective in suppressing both the generation of spasms and hypsarrhythmia in the TTX model. Vigabatrin also appears to preferentially suppress the generation of abnormal HFOs, thus implicating neocortical HFOs in the infantile spasms disease state. Copyright © 2015 Elsevier Inc.

Friedreich's ataxia (FA) is the most frequent hereditary ataxia syndrome, while painful muscle spasms and spasticity have been reported in 11-15% of FA patients. This report describes the successful management of painful spasms in a 65-year-old woman with FA via intrathecal baclofen (ITB) therapy following unsuccessful medical treatments. To our knowledge, this is the third reported case in the literature. Unfortunately, the pathophysiological characteristics of muscle spasms in FA are not well explored and understood while the therapeutic mechanisms of the different treatments are rather vague. Taking into consideration the suggested spinal atrophy in FA, the clinical resemblance of FA and chronic spinal injury muscle spasms, together with the rapid ITB therapy effectiveness in alleviating FA muscle spasms, we attempted to suggest a putative pathophysiological mechanism acting at the spinal level and possibly explained by the presence of independent spinal locomotor systems producing muscle spasms. Specifically, overexcitement of these centers, due to loss of normal regulation from upper CNS levels, may result in the uncontrolled firing of secondary motor neurons and may be the key to producing muscle spasms. However, further research under experimental and clinical settings seems to be necessary. © 2018 S. Karger AG, Basel.

Through three-dimensional real time imaging, augmented reality (AR) can provide an overlay of the anatomical structure, or visual cues for specific landmarks. In this study, an AR Toolkit was used for distraction osteogenesis with hemifacial microsomia to define the mandibular osteotomy line and assist with intraoral distractor placement. 20 patients with hemifacial microsomia were studied and were randomly assigned to experimental and control groups. Pre-operative computed tomography was used in both groups, whereas AR was used in the experimental group. Afterwards, pre- and post-operative computed tomographic scans of both groups were superimposed, and several measurements were made and analysed. Both the conventional method and AR technique achieved proper positioning of the osteotomy planes, although the AR was more accurate. The difference in average vertical distance from the coronoid and condyle process to the pre- and post-operative cutting planes was significant (p < 0.01) between the two groups, whereas no significant difference (p > 0.05) was observed in the average angle between the two planes. The difference in deviations between the intersection points of the overlaid mandible across two cutting planes was also significant (p < 0.01). This study reports on an efficient approach for guiding intraoperative distraction osteogenesis. Augmented reality tools such as the AR Toolkit may be helpful for precise positioning of intraoral distractors in patients with hemifacial microsomia in craniofacial surgery.

We report the case of an emmetropic 32-year-old female with decreased uncorrected visual acuity and diplopia due to intermittent episodes of spasm of the near reflex. Neurologic, general, and ophthalmic examination could not find an organic cause. Attempts at spontaneous recovery, psychogenic therapy, and cycloplegic therapy were unsuccessful and the symptoms persisted for almost 5 years, leading to psychogenic distress. Final treatment with refractive lens exchange and implantation of a toric trifocal intraocular lens resolved the spasm of the near reflex, resulting in an uncorrected distance and near visual acuity of 20/20.

To explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology. The patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation. The distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved. Rapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

2008-12-01

The paralysis of the ramus marginalis mandibulae nervus facialis may occur in Hemifacial Microsomia (HM); the combination of both HM and palsy contributes to an elongation of the mandibular body. This study explores a possible correlation between neurological deficit, muscular atony, and structural deficiency. Of 58 patients with HM who had come to the University of Rome (Sapienza) Pre-surgical Orthodontics Unit, 4 patients were afflicted with Hemifacial Microsomia and ramus marginalis mandibulae nervus palsy; these patients underwent physical, neurological, opthamologic and systemic examinations. The results were then analysed in order to determine a possible correlation between neuro-muscular and structural deficit. Electroneurographic and electromyographic examinations were performed to estimate facial nerve and muscles involvement. Neuroelectrographic exam showed a damage of the nervous motor fibres of the facial nerve ipsilateral to HM, with an associated damage of the muscular function, while neuro-muscular functions on the healthy side were normal. The peripheral nervous and muscular deficits affect the function of facial soft tissues and the growth of mandibular body with an asymmetry characterised by a hypodevelopment of the ramus (due to the HM) and by an elongation of the mandibular body (due to ramus marginalis mandibulae nerve palsy), so that the chin deviation is contralateral to HM. In these forms, a neurological examination is necessary to assess the neurological damage on the HM side. Neuromuscular deficiency can also contribute to a relapse tendency after a surgical-orthodontic treatment.

Unusual Presentation of Spasm of Near Reflex Mimicking Large-Angle Acute Acquired Comitant Esotropia

Abstract We report the case of an 11-year-old boy who presented with sudden esotropia, binocular diplopia, and blurred vision. The patient was neurologically normal. He had a large, constant, comitant, alternating esotropia associated with minimal accommodative spasm. Ocular motility and pupillary reactions were normal. He was diagnosed to have spasm of the near reflex presenting as acute onset of esotropia. The esotropia was persistent despite treatment and eventually resolved with prolonged cycloplegic therapy. This unusual case illustrates that spasm of the near reflex can have unique and variable presentations. Spasm of the near reflex needs to be considered in the differential diagnosis of every case of acute, acquired, comitant esotropia. This is the first case of spasm of the near reflex where persistent esotropia is reported in the absence of any neurological disorder. PMID:27928354

Coronary Artery Spasm: Review and Update

PubMed Central

Hung, Ming-Jui; Hu, Patrick; Hung, Ming-Yow

Coronary artery spasm (CAS), an intense vasoconstriction of coronary arteries that causes total or subtotal vessel occlusion, plays an important role in myocardial ischemic syndromes including stable and unstable angina, acute myocardial infarction, and sudden cardiac death. Coronary angiography and provocative testing usually is required to establish a definitive diagnosis. While the mechanisms underlying the development of CAS are still poorly understood, CAS appears to be a multifactorial disease but is not associated with the traditional risk factors for coronary artery disease. The diagnosis of CAS has important therapeutic implications, as calcium antagonists, not β-blockers, are the cornerstone of medical treatment. The prognosis is generally considered benign; however, recurrent episodes of angina are frequently observed. We provide a review of the literature and summarize the current state of knowledge regarding the pathogenesis of CAS. PMID:25249785

To determine the efficacy of the ketogenic diet in controlling epileptic spasms after failing traditional antiepileptic medication therapy. This is a prospective, case-based study of all infants with epileptic spasms who were referred for treatment with the ketogenic diet at our hospital between 2009 and 2012. All subjects continued to have epileptic spasms with evidence of hypsarrhythmia or severe epileptic encephalopathy on electroencephalography despite appropriate medication treatments. The diet efficacy was assessed through clinic visits, phone communications, and electroencephalography. Quality of life improvement was charted based on the caregiver's perspective. Twenty infants (15 males) were included in the study. The mean age at seizure onset was 4.5 months. Age at ketogenic diet initiation was 0.3 to 2.9 years (mean 1.20, standard deviation 0.78). Fifteen patients had epileptic spasms of unknown etiology; three had perinatal hypoxic ischemic encephalopathy, one had lissencephaly, and one had STXBP1 mutation. Fifteen infants failed to respond to adrenocorticotropin hormone and/or vigabatrin before going on the ketogenic diet. Three months after starting the diet, >50% seizure reduction was achieved in 70% of patients (95% CI 48-86). These results were maintained at 6- and 12-month intervals. All eight of the patients followed for 24 months had >50% seizure reduction (95% CI 63-100). At least 90% seizure reduction was reported in 20% of patients at 3 months (95% CI 7-42), 22% (95% CI 8-46) at 6 months, and 35% (95% CI 17-59) at 12 months. The majority of patients (63%) achieved improvement of their spasms within 1 month after starting the diet. Sixty percent of patients had electroencephalographic improvement. All caregivers reported improvement of the quality of life at the 3-month visit (95% confidence interval 81-100). This ratio was 94% at 6 months (95% CI 72-99) and 82% at 12 months (95% CI 58-95).

Increased reactive oxygen species (ROS) contributes to the development of endothelial dysfunction, which is involved in coronary artery spasm (CAS). Xanthine oxidoreductase (XOR) plays a pivotal role in producing both uric acid and ROS. However, the association between plasma XOR activity and CAS has not been elucidated. The aim of this study was to investigate whether plasma XOR activity is associated with CAS. We measured XOR activity in 104 patients suspected for CAS, who presented without significant coronary artery stenosis and underwent intracoronary acetylcholine provocation tests. CAS was provoked in 44 patients and they had significantly higher XOR activity as compared with those without CAS. The patients were divided into three groups based on the XOR activity. The prevalence rate of CAS was increased with increasing XOR activity. A multivariate logistic regression analysis showed that the 3rd tertile group exhibited a higher incidence of CAS as compared with the 1st tertile group [odds ratio (OR) 6.9, P = 0.001) and the 2nd tertile group (OR 3.2, P = 0.033) after adjustment for conventional CAS risk factors, respectively. The C index was significantly improved by the addition of XOR activity to the baseline model based on CAS risk factors. Furthermore, the 3rd tertile group had the highest incidence of severe spasm defined as total obstruction, flow-limiting stenosis, diffuse spasm, multivessel spasm, and/or lethal arrhythmia. This is a first report to elucidate the association of plasma XOR activity with CAS. Increased plasma XOR activity is significantly associated with CAS.

Intraoperative transesophageal echocardiography (TEE) was performed on a 62-year-old man who underwent abdominal aortic replacement for abdominal aortic aneurysm under general anesthesia combined with epidural anesthesia. Coronary artery spasm occurred after unexpected massive hemorrhage, and TEE showed hypokinesis in the posterior-inferior left ventricular wall. The changes in TEE preceded the ST elevation in the ECG. Bolus infusion of isosorbide dinitrate and continuous infusion of nitroglycerin alleviated these changes. TEE enabled us to detect and evaluate coronary spasm before the appearance of ST changes in ECG.

OBJECTIVES Arterial graft spasm occasionally causes circulatory collapse immediately following coronary artery bypass graft. The aim of this study is to evaluate the efficacy of our developed materials, which were composed of milrinone (phosphodiesterase III inhibitor) or diltiazem (calcium-channel blocker), with nano-scaled fibre made of biodegradable polymer to prevent arterial spasm. METHODS Milrinone- or diltiazem-releasing biodegradable nano-scaled fibres were fabricated by an electrospinning procedure. In vivo milrinone- or diltiazem-releasing tests were performed to confirm the sustained release of the drugs. An in vivo arterial spasm model was established by subcutaneous injection of noradrenalin around the rat femoral artery. Rats were randomly divided into four groups as follows: those that received 5 mg of milrinone-releasing biodegradable nano-scaled fibre (group M, n = 14); 5 mg of diltiazem-releasing biodegradable nano-scaled fibre (group D, n = 12); or those that received fibre without drugs (as a control; group C, n = 14) implanted into the rat femoral artery. In the fourth group, sham operation was performed (group S, n = 10). One day after the implantation, noradrenalin was injected in all groups. The femoral arterial blood flow was measured continuously before and after noradrenalin injection. The maximum blood flow before noradrenalin injection and minimum blood flow after noradrenalin injection were measured. RESULTS In vivo drug-releasing test revealed that milrinone-releasing biodegradable nano-scaled fibre released 78% of milrinone and diltiazem-releasing biodegradable nano-scaled fibre released 50% diltiazem on the first day. The ratios of rat femoral artery blood flow after/before noradrenalin injection in groups M (0.74 ± 0.16) and D (0.72 ± 0.05) were significantly higher than those of groups C (0.54 ± 0.09) and S (0.55 ± 0.16) (P < 0.05). CONCLUSION Noradrenalin-induced rat femoral artery spasm was inhibited by the implantation of

Objective: To summarize the gene mutation of early onset epileptic spasm with unknown reason. Method: In this prospective study, data of patients with early onset epileptic spasm with unknown reason were collected from neurological department of Children's Hospital of Fudan University between March 2016 and December 2016. Patients with known disorders such as infection, metabolic, structural, immunological problems and known genetic mutations were excluded. Patients with genetic disease that can be diagnosed by clinical manifestations and phenotypic characteristics were also excluded. Genetic research methods included nervous system panel containing 1 427 epilepsy genes, whole exome sequencing (WES), analysis of copy number variation (CNV) and karyotype analysis of chromosome. The basic information, phenotypes, genetic results and the antiepileptic treatment of patients were analyzed. Result: Nine of the 17 cases with early onset epileptic spasm were boys and eight were girls. Patients' age at first seizure onset ranged from 1 day after birth to 8 months (median age of 3 months). The first hospital visit age ranged from 1 month to 2 years (median age of 4.5 months). The time of following-up ranged from 8 months to 3 years and 10 months. All the 17 patients had early onset epileptic spasm. Video electroencephalogram was used to monitor the spasm seizure. Five patients had Ohtahara syndrome, 10 had West syndrome, two had unclear classification. In 17 cases, 10 of them had detected pathogenic genes. Nine cases had point mutations, involving SCN2A, ARX, UNC80, KCNQ2, and GABRB3. Except one case of mutations in GABRB3 gene have been reported, all the other cases had new mutations. One patient had deletion mutation in CDKL5 gene. One CNV case had 6q 22.31 5.5MB repeats. Ten cases out of 17 were using 2-3 antiepileptic drugs (AEDs) and the drugs had no effect. Seven cases used adrenocorticotropic hormone (ACTH) and prednisone besides AEDs (a total course for 8 weeks

In this paper the authors' goal was to evaluate the feasibility and efficacy of a virtual reality (VR) system in preoperative planning for microvascular decompression (MVD) procedures treating idiopathic trigeminal neuralgia and hemifacial spasm. The system's role in surgical simulation and training was also assessed. Between May 2008 and April 2009, the authors used the Dextroscope system to visualize the neurovascular complex and simulate MVD in the cerebellopontine angle in a VR environment in 16 patients (6 patients had trigeminal neuralgia and 10 had hemifacial spasm). Reconstructions were carried out 2-3 days before MVD. Images were printed in a red-blue stereoscopic format for teaching and discussion and were brought into the operating room to be compared with real-time intraoperative findings. The VR environment was a powerful aid for spatial understanding of the neurovascular relationship in MVD for operating surgeons and trainees. Through an initial series of comparison/confirmation experiences, the senior neurosurgeon became accustomed to the system. He could predict intraoperative problems and simulate surgical maneuvering, which increased his confidence in performing the procedure. The Dextroscope system is an easy and rapid method to create a stereoscopic neurovascular model for MVD that is highly concordant with intraoperative findings. It effectively shortens the learning curve and adds to the surgeon's confidence.

Intermittent exotropia (IXT) is an exodeviation intermittently controlled by fusional mechanisms. Patients with IXT may present with asthenopic symptoms, blurred vision, headaches, diplopia or visual confusion and reading difficulties; especially after prolonged periods of near work. To report the presentation and management of a young adult with intractable accommodative spasm secondary to long standing intermittent exotropia. The patient was found to have bilateral accommodative spasm with high pseudomyopia and severe impairment of vision. There was a tendency for recurrence with discontinuation of cycloplegics. A total relief of symptoms was noticed after strabismus surgery was undertaken for the exotropia. A detailed orthoptic evaluation with emphasis on recognizing accommodative spasm as an unusual presentation of IXT, could aid in appropriate diagnosis and treatment of such cases. © NEPjOPH.

A 51-year-old man with a resuscitation episode was referred to our hospital. Coronary angiography revealed a focal spasm overlapped with organic stenosis where a bare metal stent was implanted. Acetylcholine (ACh) provocation test did not induce chest pain. It revealed no discernible ST-T changes but unmasked a J wave at the end of the QRS complex, which was associated with short-coupled repetitive premature ventricular beats. A J wave reportedly appears immediately before the onset of ventricular fibrillation caused by vasospastic angina. However, a J wave observed newly after a coronary spasm provocation test using ACh without ST-T changes is informative when considering the mechanisms of the J wave.

Maxillary-driven simultaneous maxillo-mandibular distraction for hemifacial microsomia.

We treat hemifacial microsomia with a combination of surgery and orthodontic treatment during the growth period, resulting in early improvement in facial asymmetry and the induction of normal growth. We previously used gradual distraction of the mandibular ramus for Pruzansky's type II classification (Pruzansky, 1969). In type II cases, the maxilla should also be treated actively as, using this technique, improvement of the occlusal plane is difficult to achieve, resulting in a cross bite and difficulties in post-operative orthodontic treatment-especially in older patients. Morphologically, the mandibular angle region of the operative side is flat, and the angle of the mouth remains elevated. We performed mandibular-driven simultaneous maxillo-mandibular distraction while the occlusion was maintained using intermaxillary anchorage. However, mandibular-driven distraction tended to elongate the face because the mandible only elongated downwards and the mandibular ramus did not reach the glenoid. Furthermore, external distraction devices produce significant distress for patients until removal of the device and cause scars on the face. We developed a new internal distraction device with a variable angle and performed maxillary-driven simultaneous maxillo-mandibular distraction using this device. The result was morphologically satisfactory and solved the above problems. Because the patient was in the growth period, careful follow-up and induction to normal growth were important while the inferior growth of the affected side was monitored.

Objective We investigated temporal and spatial characteristics of ictal gamma and beta activity on scalp EEG during spasms in patients with West syndrome (WS) to evaluate potential focal cortical onset. Methods A total of 1033 spasms from 34 patients with WS of various etiologies were analyzed in video-EEG using time-frequency analysis. Ictal gamma (35–90 Hz) and beta (15–30 Hz) activities were correlated with visual symmetry of spasms, objective EMG (electromyography) analysis, and etiology of WS. Results Prior to the ictal motor manifestation, focal ictal gamma activity emerged from one hemisphere (71%, 24/34) or from midline (26%, 9/34), and was rarely simultaneously bilateral (3%, 1/34). Focal ictal beta activity emerged from either one hemisphere (68%, 23/34) or from midline (32%, 11/34). Onsets of focal ictal gamma and beta activity were most commonly observed around the parietal areas. Focal ictal gamma activity propagated faster than ictal beta activity to adjacent electrodes (median: 65 vs. 170 ms, p<0.01), and to contralateral hemisphere (median: 100 vs. 170 ms, p=0.01). Asymmetric peak amplitude of ictal gamma activity in the centroparietal areas (C3-P3 vs. C4-P4) correlated with asymmetric semiology. On the other hand, the majority of visually symmetric spasms showed asymmetry in peak amplitude and interhemispheric onset latency difference in both ictal gamma and beta activity. Significance Spasms may be a seizure with focal electrographic onset regardless of visual symmetry. Asymmetric involvement of ictal gamma activity to the centroparietal areas may determine the motor manifestations in WS. Scalp EEG ictal gamma and beta activity may be useful to demonstrate localized seizure onset in infants with WS. PMID:28397999

Background We previously showed that phospholipase C (PLC)-δ1 activity was enhanced by 3-fold in patients with coronary spastic angina (CSA). We also reported that p122Rho GTPase-activating protein/deleted in liver cancer-1 (p122RhoGAP/DLC-1) protein, which was discovered as a PLC-δ1 stimulator, was upregulated in CSA patients. We tested the hypothesis that p122RhoGAP/DLC-1 overexpression causes coronary spasm. Methods and Results We generated transgenic (TG) mice with vascular smooth muscle (VSM)-specific overexpression of p122RhoGAP/DLC-1. The gene and protein expressions of p122RhoGAP/DLC-1 were markedly increased in the aorta of homozygous TG mice. Stronger staining with anti-p122RhoGAP/DLC-1 in the coronary artery was found in TG than in WT mice. PLC activities in the plasma membrane fraction and the whole cell were enhanced by 1.43 and 2.38 times, respectively, in cultured aortic vascular smooth muscle cells from homozygous TG compared with those from WT mice. Immediately after ergometrine injection, ST-segment elevation was observed in 1 of 7 WT (14%), 6 of 7 heterozygous TG (84%), and 7 of 7 homozygous TG mice (100%) (p<0.05, WT versus TGs). In the isolated Langendorff hearts, coronary perfusion pressure was increased after ergometrine in TG, but not in WT mice, despite of the similar response to prostaglandin F2α between TG and WT mice (n = 5). Focal narrowing of the coronary artery after ergometrine was documented only in TG mice. Conclusions VSM-specific overexpression of p122RhoGAP/DLC-1 enhanced coronary vasomotility after ergometrine injection in mice, which is relevant to human CSA. PMID:26624289

The progression of certain primary esophageal motor disorders to achalasia has been documented; however, the true incidence of this decay is still elusive. This study aims to evaluate: (i) the incidence of the progression of diffuse esophageal spasm to achalasia, and (ii) predictive factors to this progression. Thirty-five patients (mean age 53 years, 80% females) with a manometric picture of diffuse esophageal spasm were followed for at least 1 year. Patients with gastroesophageal reflux disease confirmed by pH monitoring or systemic diseases that may affect esophageal motility were excluded. Esophageal manometry was repeated in all patients. Five (14%) of the patients progressed to achalasia at a mean follow-up of 2.1 (range 1-4) years. Demographic characteristics were not predictive of transition to achalasia, while dysphagia (P= 0.005) as the main symptom and the wave amplitude of simultaneous waves less than 50 mmHg (P= 0.003) were statistically significant. In conclusion, the transition of diffuse esophageal spasm to achalasia is not frequent at a 2-year follow-up. Dysphagia and simultaneous waves with low amplitude are predictive factors for this degeneration. © 2012 Copyright the Authors.

Objective Infantile spasms (IS) are among the most catastrophic epileptic syndromes of infancy. The purpose of this study was to compare efficacy and safety of topiramate (TPM) and nitrazepam (NZP) as first-line drugs in the treatment of IS. Materials & Methods In a parallel single-blinded randomized clinical trial, 50 patients with IS referred to Pediatric Neurology Clinic of Shahid Sadoughi University of Medical Sciences, Yazd, Iran, were evaluated from September 2008 to March 2010. Patients were randomly assigned to two groups to be treated with TPM or with NZP for 6 months. The primary endpoint was efficacy in cessation of all spasms or reduction of more than 50% in weekly seizure frequency, which was evaluated before and 6 months after the drug use. Secondary outcome was clinical sideeffects of the drugs. Results Twenty boys (40%) and 30 girls (60%) with the mean age of 9.4±3.8 months were evaluated. Cessation of all spasms occurred in 12 (48%) infants in TPM group and 4(16%) in NZP group. Eight (32%) children in TPM group and 7 (28%) in NZP group had more than 50% reduction in spasms frequency. So, TPM was more effective. Side effects were seen in 32% of TPM and in 36% of NZP groups. Conclusion Topiramate is an effective and safe drug, which might be considered as the firstline drug for the treatment of ISs. PMID:24665322

Numerous studies have suggested that the ketogenic diet is effective in the treatment of epileptic spasms, even in refractory cases. However, there has been very limited demonstration of prompt and complete (video-EEG confirmed) response. We set out to describe our center's experience with the ketogenic diet in the treatment of children with highly refractory epileptic spasms, with rigorous seizure outcome assessment. Children treated with the ketogenic diet for epileptic spasms between April, 2010 and June, 2014 were retrospectively identified. Seizure burden was tabulated at baseline and after 1, 3, 6, and 12-months of ketogenic diet exposure. Adverse events were similarly ascertained. We identified a cohort of 22 consecutive patients who received ketogenic diet therapy, with median age of onset of epileptic spasms of 5.2 (IQR 2.0-9.0) months, with diet initiation beginning a median of 26.4 (12.5-38.7) months after onset, and following a median of 7 (IQR 5-7) treatment failures. Only 2 patients exhibited a complete response during ketogenic diet exposure, and response was more reasonably attributed to alternative therapies in both cases. A modest early reduction in seizure frequency was not sustained beyond 1 month of diet exposure. The diet was well tolerated, and continued in 6 patients with subjective and/or partial response. In contrast to prior studies reporting substantial efficacy of the ketogenic diet, our findings suggest limited efficacy, albeit in a highly refractory cohort. Prospective studies in both refractory and new-onset populations, with both video-EEG confirmation of response and rigorous cognitive outcome assessment, would be of great value to more clearly define the utility of the ketogenic diet in the treatment of epileptic spasms.

Continuous myocloni and tonic spasms in a 2-month-old infant with enterovirus 71 brain stem encephalitis.

PubMed

Lee, Kyung Yeon; Yeh, Hye-Ryun

2015-02-01

Brain stem encephalitis is a cardinal presentation of central nervous system involvement in enterovirus 71 infection, and manifests as myoclonus, ataxia, tremor, and autonomic dysfunction. A 2-month-old infant with enterovirus 71 brain stem encephalitis demonstrated continuous myocloni and tonic spasms. On admission, the patient's myoclonus, which mainly involved the shoulders and the arms, was considerably worse during wakefulness and occurred once or twice a minute. Several hours after admission, the myoclonic jerks steadily worsened, appeared ceaselessly every 1 to 2 seconds, and were intermixed with tonic spasms of all four extremities accompanied by crying. Video electroencephalography revealed a normal background without epileptiform discharges and no ictal electroencephalographic changes during the myoclonic jerks and tonic spasms. Complete remission was achieved without complications after completion of a 3-day immunoglobulin therapy. This case suggests that the brain stem may be a major origin site for not only myoclonus but also tonic spasm. Georg Thieme Verlag KG Stuttgart · New York.

Romberg disease is an uncommon condition manifested by progressive hemifacial atrophy of the skin, soft tissue, and bone. Facial asymmetry with soft tissue deficiency in Romberg disease causes a significant disability affecting the social life and can bring about many psychological problems. The aim of surgical treatment is cosmetic amelioration of the defect. Several conventional reconstructive procedures have been used for correcting facial asymmetry. They include fat injections, dermal fat grafts, filler injections, cartilage and bone grafts, and pedicled and free flaps. We report our experiences with 11 patients involving 11 free flaps with a minimum 1-year follow-up. All patients were classified as having moderate to severe atrophy. The average age at disease onset was 4.5 years; the average duration of atrophy was 5.2 years. No patients were operated on with a quiescent interval of less than 1 year. The average age at operation was 20.1 years, ranging from 10 to 55 years. Reconstruction was performed using 4 groin dermofat free flaps, 4 latissimus dorsi muscle free flaps, and 3 other perforator flaps. To achieve the finest symmetrical and aesthetic results, several ancillary procedures were performed in 4 patients. These procedures included Le Fort I leveling osteotomy, sagittal split ramus osteotomy, reduction malarplasty and angle plasty, rib and calvarial bone graft, correction of alopecia, and additional fat graft. All patients were satisfied with the results. We believe that a free flap transfer is the requisite treatment modality for severe degree of facial asymmetry in Romberg disease.

Clinical profile of vigabatrin as monotherapy for treatment of infantile spasms

Lerner, Jason T; Salamon, Noriko; Sankar, Raman

2010-01-01

Vigabatrin, the first therapeutic agent to be approved by the Food and Drug Administration for the treatment of infantile spasms, as well as for adjunctive use in the treatment of refractory complex partial epilepsy, represents an important advance for patients with difficult-to-manage epilepsy. This review summarizes the complex history, chemistry, and pharmacology, as well as the clinical data leading to the approval of vigabatrin for infantile spasms in the US. The long path to its approval reflects the visual system and white matter toxicity concerns with this agent. This review provides a brief description of these concerns, and the regulatory safety monitoring and mitigation systems that have been put in place to enhance benefit over risk. PMID:21127692

Vaginal spasm, pain, and behavior: an empirical investigation of the diagnosis of vaginismus.

Reissing, Elke D; Binik, Yitzchak M; Khalifé, Samir; Cohen, Deborah; Amsel, Rhonda

2004-02-01

This study investigated the roles of vaginal spasm, pain, and behavior in vaginismus and the ability of psychologists, gynecologists, and physical therapists to agree on a diagnosis of vaginismus. Eighty-seven women, matched on age, relationship status, and parity, were assigned to one of three groups: vaginismus, dyspareunia resulting from vulvar vestibulitis syndrome (VVS), and no pain with intercourse. Diagnostic agreement was poor for vaginismus; vaginal spasm and pain measures did not differentiate between women in the vaginismus and dyspareunia/VVS groups; however, women in the vaginismus group demonstrated significantly higher vaginal/pelvic muscle tone and lower muscle strength. Women in the vaginismus group also displayed a significantly higher frequency of defensive/avoidant distress behaviors during pelvic examinations and recalled past attempts at intercourse with more affective distress. These data suggest that the spasm-based definition of vaginismus is not adequate as a diagnostic marker for vaginismus. Pain and fear of pain, pelvic floor dysfunction, and behavioral avoidance need to be included in a multidimensional reconceptualization of vaginismus.

We investigated the efficacy and safety of nitroglycerin for preventing venous spasm during contrast-guided axillary vein puncture for pacemaker or defibrillator leads implantation. A total of 40 consecutive patients referred for contrast-guided axillary vein puncture for pacemaker or defibrillator implantations were included in the study. Patients were randomly assigned to control group and nitroglycerin group. Patients in the nitroglycerin group were given 200 µg (2 mL) nitroglycerin via ipsilateral peripheral vein about 3 min before puncture. The degree of venous spasm was evaluated by the reduction in lumen calibre of the axillary vein after puncture. Mild venous spasm and severe venous spasm were defined as a reduction in lumen calibre of 50-90% and ≥ 90%, respectively. The mean degree of venous spasm of axillary vein was lower in the nitroglycerin group than in the control group (23.0 ± 22.3 vs. 45.5 ± 33.6%, P = 0.018). The incidence of mild or severe venous spasm was lower in the nitroglycerin group than in the control group (3/20 vs. 11/20, P = 0.019). In the nitroglycerin group, the systolic blood pressure had a significant decrease after puncture (129.5 ± 23.7 vs. 143.0 ± 24.1 mmHg, P = 0.003). There was no hypotension and other adverse reaction of nitroglycerin in the nitroglycerin group. Intravenous nitroglycerin is effective and safe for preventing venous spasm during contrast-guided axillary vein puncture for pacemaker or defibrillator leads implantation.

Background In this study, we investigated whether the infusion of bone marrow-derived mesenchymal stem cells (MSCs), combined with transient immunosuppressant treatment, could suppress allograft rejection and modulate T-cell regulation in a swine orthotopic hemi-facial composite tissue allotransplantation (CTA) model. Methodology/Principal Findings Outbred miniature swine underwent hemi-facial allotransplantation (day 0). Group-I (n = 5) consisted of untreated control animals. Group-II (n = 3) animals received MSCs alone (given on days −1, +1, +3, +7, +14, and +21). Group-III (n = 3) animals received CsA (days 0 to +28). Group-IV (n = 5) animals received CsA (days 0 to +28) and MSCs (days −1, +1, +3, +7, +14, and +21). The transplanted face tissue was observed daily for signs of rejection. Biopsies of donor tissues and recipient blood sample were obtained at specified predetermined times (per 2 weeks post-transplant) or at the time of clinically evident rejection. Our results indicated that the MSC-CsA group had significantly prolonged allograft survival compared to the other groups (P<0.001). Histological examination of the MSC-CsA group displayed the lowest degree of rejection in alloskin and lymphoid gland tissues. TNF-α expression in circulating blood revealed significant suppression in the MSC and MSC-CsA treatment groups, as compared to that in controls. IHC staining showed CD45 and IL-6 expression were significantly decreased in MSC-CsA treatment groups compared to controls. The number of CD4+/CD25+ regulatory T-cells and IL-10 expressions in the circulating blood significantly increased in the MSC-CsA group compared to the other groups. IHC staining of alloskin tissue biopsies revealed a significant increase in the numbers of foxp3+T-cells and TGF-β1 positive cells in the MSC-CsA group compared to the other groups. Conclusions These results demonstrate that MSCs significantly prolong hemifacial CTA survival. Our data indicate the MSCs

Celiac disease is an immune-mediated disorder elicited by ingestion of gluten in genetically susceptible persons. This disorder is characterized by specific histological changes of the small intestine mucosa resulting in malabsorption. This case was written up as it was an unusual and dramatic presentation of celiac disease. We report the case of a 3-year-old Albanian girl who presented at our clinic with carpal spasms and hand paresthesia. A physical examination at admission revealed a relatively good general condition and body weight of 10.5 kg (10 percentile). Carpal spasms and paresthesias of her extremities were present. Neuromuscular irritability was demonstrated by positive Chvostek and Trousseau signs. Blood tests showed severe hypocalcemia with a total serum calcium of 1.2 mmol/L (normal range 2.12 to 2.55 mmol/L), ionized calcium of 0.87 (normal range 1.11 to 1.30 mmol/L), and 24-hour urine calcium excretion of 9.16 mmol (normal range female <6.2 mmol/day). Among other tests, screening for celiac disease was performed: antigliadin immunoglobulin A, anti-tissue transglutaminase, and anti-endomysial immunoglobulin A antibodies were positive. A duodenal biopsy revealed lymphocyte infiltration, crypt hyperplasia, and villous atrophy compatible with celiac disease grade IIIb according to the Marsh classification. Following the diagnosis of celiac disease, human leukocyte antigen typing was performed, giving a definite diagnosis of celiac disease. She was started on a gluten-free diet. Due to failure to follow a gluten-free diet, episodes of carpal spasms appeared again. Unfortunately, at the age of 7 years she presents with delayed psychophysical development. Although hypocalcemia is a common finding in celiac disease, hypocalcemic carpal spasm is a rare initial manifestation of the disease. Therefore, the possibility of celiac disease should be considered in patients with repeated carpal spasms that seem unduly difficult to treat. This should be

CDKL5/STK9 is mutated in Rett syndrome variant with infantile spasms

Background: Rett syndrome is a severe neurodevelopmental disorder, almost exclusively affecting females and characterised by a wide spectrum of clinical manifestations. Both the classic form and preserved speech variant of Rett syndrome are due to mutations in the MECP2 gene. Several other variants of Rett syndrome have been described. In 1985, Hanefeld described a variant with the early appearance of convulsions. In this variant, the normal perinatal period is soon followed by the appearance of seizures, usually infantile spasms. We have observed two patients with signs of Rett syndrome showing acquired microcephaly and stereotypic midline hand movements. The disease started with generalised convulsions and myoclonic fits at 1.5 months in the first patient and with spasms at 10 days in the other, suggesting a diagnosis of the Hanefeld variant. In these patients, MECP2 point mutations and gross rearrangements were excluded by denaturing high performance liquid chromatography and real time quantitative PCR. The ARX and CDKL5 genes have been associated with West syndrome (infantile spasms, hypsarrhythmia, and mental retardation). Methods: Based on the clinical overlap between the Hanefeld variant and West syndrome, we analysed ARX and CDKL5 in the two girls. Results: We found frameshift deletions in CDKL5 in both patients; one in exon 5 (c.163_166delGAAA) and the other in exon 18 (c.2635_2636delCT). CDKL5 was then analysed in 19 classic Rett and 15 preserved speech variant patients, all MECP2 negative, but no mutations were found. Conclusion: Our results show that CDKL5 is responsible for a rare variant of Rett syndrome characterised by early development of convulsions, usually of the spasm type. PMID:15689447

Noninvasive ergonovine maleate provocative testing for coronary artery spasm: the need for routine thallium-201 imaging

We administered ergonovine and used both electrocardiographic monitoring and thallium-/sup 201/ (/sup 201/Tl) imaging to detect reversible ischemia in 100 patients. Patients already established as having coronary artery spasm and those with nonbypassed, proximal, high-grade coronary artery stenosis were excluded. No complication occurred in any patient. The use of thallium imaging in addition to electrocardiographic monitoring resulted in a higher degree of sensitivity than did ECG monitoring alone. Fourteen patients demonstrated evidence of coronary artery spasm as documented by /sup 201/Tl imaging but of the 14, significant ECG changes occurred in only 50%, and classic ST segment elevation in 21%.more » Thus, in carefully selected patients the noninvasive provocation of coronary spasm can be accomplished safely, but ECG monitoring must be combined with thallium-/sup 201/ imaging to achieve an acceptable degree of sensitivity.« less

Methamphetamine-associated acute myocardial infarction and cardiogenic shock with normal coronary arteries: refractory global coronary microvascular spasm.

PubMed

Chen, Jack P

2007-04-01

Methamphetamine (MET) is a growing public health concern and is prevalent in, although not limited to, the youth. The drug's association with myocardial infarction is well described and is attributed to accelerated atherosclerosis, hypercoagulable state, and macrovascular epicardial coronary spasm. However, global slow-flow of all coronary systems in the absence of significant stenoses has not been previously reported. We hereby present a young patient who likely experienced severe, global microvascular coronary spasm unrelieved by intracoronary vasodilator therapy, resulting in acute myocardial infarction. The pharmacology of MET, its postulated mechanism in acute coronary syndromes, as well as the pathophysiology and treatments of microvascular coronary spasm are briefly reviewed. Readers are recommended to be vigilant of potential illicit drug use in patients with atypical presentations of acute coronary syndromes.

To report the ophthalmic findings and response to treatment in a patient with glutamic-acid decarboxylase antibodies. Case report. A 55-year-old woman developed progressive, painful, low back muscle spasms, vertical diplopia, downbeating nystagmus, and asymmetric appendicular ataxia. Downbeating nystagmus was present in primary gaze with an alternating skew deviation in lateral gaze. Serum and cerebrospinal fluid GAD antibodies were detected. Treatment with diazepam led to resolution of spasticity, whereas repeated courses of intravenous immunoglobulin improved cerebellar function, including appendicular ataxia and downbeating nystagmus. Patients with GAD antibodies may have elements of both Stiff-person syndrome (muscle rigidity and spasms) and prominent cerebellar dysfunction. Treatment with diazepam rapidly improved Stiff-person symptoms, whereas IVIg was partially effective at the early stage of cerebellar dysfunction.

Hemifacial microsomia: from gestation to childhood.

Hemifacial microsomia (HFM) is a variable, complex malformation involving asymmetric hypoplasia of the face and ear. Little is known about the risk factors for or consequences of HFM. In this study, we describe 3 studies that have been or are currently being conducted to further our understanding of this malformation. The first completed study examined whether HFM risk is related to maternal exposures that may affect blood flow. In that case-control study, interview data from 230 mothers of children in the case group and 678 mothers of children in the control group suggested that maternal use of vasoactive medications in the first trimester, particularly in combination with cigarette smoking, was associated with increased risks of HFM. The second study is currently underway, in which we are evaluating whether HFM risk is related to genetic variation in pathways associated with vasculogenesis and hemostasis, using DNA collected in the first study. The third ongoing study observes children with HFM to identify psychosocial, cognitive, dental, and medical sequelae. When the children from the original case-control study are 6 or 7 years of age, mothers and teachers complete self-administered questionnaires that cover a wide range of psychosocial development domains. Preliminary analyses of 115 case and 314 control children suggest that children with HFM may have worse teacher-reported academic performance and possibly higher levels of internalizing behavior problems than control children. When data on the full study sample are available, further analyses will determine whether the preliminary findings remain and if they vary by HFM phenotype, parenting style, or indicators of social risk.

Sphenopalatine (nasal) ganglion: remote effects including "psychosomatic" symptoms, rage reaction, pain, and spasm.

PubMed

Ruskin, A P

1979-08-01

Many articles implicate the nasal ganglion in the production of remote symptoms and discuss treatment. Symptoms are primarily spastic, involving both visceral and voluntary muscles including muscle spasm in the neck, shoulder, and low back; asthma, hypertension, intestinal spasm; diarrhea, angina pectoris, uterine spasm; intractable hiccup, and many others. All these symptoms appear to have 2 common denominators. They are mediated by the autonomic nervous system and at least in some instances can be "psychosomatic." The sphenopalatine ganglion (SPG) is a major autonomic ganglion located superficially in the pterygopalatine fossa, with major afferent distribution to the entire nasopharynx and important connections with the trigeminal nerve, facial nerve, internal carotid artery plexus of the sympathetic nervous system and, as shown in the rat, direct connection with the anterior pituitary gland. This paper presents arguments supporting the following hypotheses: 1. The SPG probably has a crucial role in lower animals in declenching the reflex responses known collectively as the rage reaction. 2. The SPG is a major point of entry to the autonomic system exposed to pathologic influences and readily accessible for therapeutic influences and readily accessible for therapeutic intervention. 3. A wide variety of symptoms are produced or maintained by alteration in autonomic system tonus and some of these may be affected by intervention on the SPG. 4. The possible relationship of some symptoms and "psychosomatic" conditions to the autonomic nervous system and the rage reaction must be considered.20

The impact of vasomotion types on long-term clinical outcomes in patients with coronary artery spasm (CAS) induced by the acetylcholine provocation test (ACH-test) remains unclear. We evaluated 4644 consecutive patients with typical resting chest pain (CP), but no angiographically significant coronary artery lesion (<50% stenosis), who underwent an ACH-test. According to their vasomotor response, patients were categorized into four types: normal vasomotion (no CP, no ischemic electrocardiographic changes, and no vasoconstriction), microvascular spasm (CP with <75% vasoconstriction but with CP relief after nitroglycerin infusion), epicardial spasm (CP with ≥75% vasoconstriction), and ACH-test inconclusive (vasoconstriction and/or electrocardiographic changes, but no CP). We investigated CP recurrence requiring follow-up angiography and major adverse cardiovascular events (MACEs) during 5 years. CP recurred in 7.9% of patients and was more frequent in abnormal vasomotion types (normal vasomotion, microvascular spasm, epicardial spasm, and inconclusive type: 5.4%, 9.8%, 10.9%, and 8.2%, respectively, log-rank p = 0.009). In multivariate analysis adjusted for medication use after the ACH-test, vasomotion subtype was not an independent predictor, whereas male sex, fixed lesion on baseline angiography, and medications including calcium channel blockers (CCBs), nitrates, and statins were independent positive predictors for recurrent CP. Alcohol consumption at the initial interview was a negative predictor. MACEs were observed in 1.6%, and the incidence was similar among subtypes (p = 0.421). Recurrent CP and long-term outcomes are independent of vasomotion subtypes, but long-term use of CCBs, nitrates, and statins is a significant predictor for recurrent CP.

Bell's palsy is unilateral, acute onset facial paralysis that is a common condition. One in every 65 people experiences Bell's palsy in the course of their lifetime. The majority of patients afflicted with this idiopathic disorder recover facial function. Initial treatment involves oral corticosteroids, possible antiviral drugs, and protection of the eye from desiccation. A small subset of patients may be left with incomplete recovery, synkinesis, facial contracture, or hemifacial spasm. A combination of medical and surgical treatment options exist to treat the long-term sequelae of Bell's palsy. Copyright © 2016 Elsevier Inc. All rights reserved.

The history of facial palsy and spasm

Sajadi, Mohamad-Reza M.; Tabatabaie, Seyed Mahmoud

2011-01-01

Although Sir Charles Bell was the first to provide the anatomic basis for the condition that bears his name, in recent years researchers have shown that other European physicians provided earlier clinical descriptions of peripheral cranial nerve 7 palsy. In this article, we describe the history of facial distortion by Greek, Roman, and Persian physicians, culminating in Razi's detailed description in al-Hawi. Razi distinguished facial muscle spasm from paralysis, distinguished central from peripheral lesions, gave the earliest description of loss of forehead wrinkling, and gave the earliest known description of bilateral facial palsy. In doing so, he accurately described the clinical hallmarks of a condition that we recognize as Bell palsy. PMID:21747074

Asphyxia due to laryngeal spasm as a severe complication of awake deep brain stimulation for Parkinson's disease: a case report.

In accordance with German neurosurgical and neurological consensus recommendations, lead placements for deep brain stimulation (DBS) in patients with Parkinson's disease (PD) are usually performed with the patient awake and in "medication off" state. This allows for optimal lead position adjustment according to the clinical response to intraoperative test stimulation. However, exacerbation of Parkinsonian symptoms after withdrawal of dopaminergic medication may endanger the patient by inducing severe "off" state motor phenomena. In particular, this can be a problem in awake craniotomies utilizing intraoperative airway management and resuscitation. We report the case of a PD patient with progressive orofacial and neck muscle dystonia resulting in laryngeal spasm during DBS lead placement. This led to upper airway compromise and asphyxia, requiring resuscitation. Laryngeal spasms may occur as a rare "off" state motor complication in patients with PD. Other potential causes of intraoperative difficulties breathing include bilateral vocal cord palsy, positional asphyxia, and silent aspiration. In our practice, we have adjusted our medication regimen and now allow patients to receive their standard dopaminergic medication until the morning of surgery. Neurologists and neurosurgeons performing lead placement procedures for PD should be aware of this rare but unsafe condition to most optimized treatment.

Epileptic spasms and early-onset photosensitive epilepsy in Patau syndrome: An EEG study.

Patau syndrome, trisomy 13, is the third commonest autosomal trisomy. It is associated with a 25-50% prevalence of epilepsy, but detailed electroclinical descriptions are rare. The occurrence of early-onset photosensitivity has recently been reported in single patients. We collected electroclinical data on 8 infants (age range from 2 months to 3 years and 9 months, median: 17 months) with Patau syndrome referred for an EEG in our Clinical Neurophysiology Department between 1991 and 2011. All EEGs, case-notes, cytogenetic diagnosis and neuroimaging when available were reviewed; data on the occurrence of seizures, epileptiform discharges, photoparoxysmal response and their characteristics in terms of positive frequencies, latencies, grade and duration were noted and analysed. Two patients had been previously diagnosed with epilepsy (one with tonic spasms and one with multiple seizure types). We found 3 patients with photosensitive myoclonic epilepsy (37.5%), and one with non-photosensitive myoclonic epilepsy. We also recorded non-epileptic myoclonic jerks in one patient known to suffer from epileptic spasms. Among photosensitive patients we found self-limited, Waltz's grade 2-4, spike-wave/polyspike-wave discharges in low, medium and high frequency ranges in two patients and in the high frequency range in the third patient, with latencies and duration from less than 1s to a maximum of 9s. In our cohort of Patau syndrome patients, we found a high prevalence of spasms and photic-induced myoclonic jerks. Photosensitivity shows an unusual early age of onset.

Meteorism, abdominal spasms, diarrhea, casually obstipation, flatulence and nausea are symptoms of fructose malabsorption (FIT) and/or lactose intolerance (LIT), but are also symptoms of irritable bowel syndrome (IBS). Therefore these diseases should be considered primarily in patients with digestive complaints. For diagnosis an H(2)-breath test is used.In 1,935 patients (526 m, 1,409 f) a fructose intolerance test and in 1,739 patients (518 m,1,221 f) a lactose intolerance test was done.FIT is found more frequently than LIT (57 versus 52 % in adults (p < 0,02) and in children 90 versus 62 % (p < 0,001)) and is in polyintolerances most frequently correlated to histamine intolerance (HIT). Headache (ca. 10 %), fatigue (ca. 5 %) and dizziness (ca. 3 %) may occur after the test, irrespective whether the test was positive or negative.In more than 2/3 of patients a diet reduced in fructose or lactose may lead to improvement or remission of these metabolic disorders. IBS, which is often correlated with FIT (183/221 patients = 83 %), can be improved by relevant but also not relevant diets indicating that irritable bowel disease seems to be caused primarily by psychological disorders.

Development of a morphing technique for predicting the position and size of an artificial ear in hemifacial microsomia patients.

PubMed

Coward, Trevor J; Richards, Robin; Scott, Brendan J J

2014-01-01

People with hemifacial microsomia may be missing an ear on the affected side of the face. The principal aim of the study was to develop a morphing technique and to determine whether it could be used to appropriately position an artificial ear, as well as to give an indication of prosthesis size in comparison with the natural ear. Comparisons also were made between the artificial ears being worn by the patients with their natural ears. Data from stereophotogrammetry images of the faces of 10 people were converted into stereolithographic format. Anthropometric points on the face and ear of the unaffected side were plotted. By a process of scaling, the distance between facial landmarks on the unaffected side was estimated for the affected side so as to identify where the morphed ear would be positioned once generated. Generally, the morphed ears appeared to be in acceptable positions. There was a statistically significant difference between the position of the morphed and natural ears (P = .011), as well as the artificial and natural ears (P = .001), but this was unlikely to have any clinical implications. There were no significant differences among the sizes of the natural, morphed, and artificial ears (P = .072). Morphing appears to offer a more precise way of planning the positioning and construction of an artificial ear on patients with hemifacial microsomia than traditional methods. Differences in facial shape on either side of the face may impact on the process. This requires further study.

Paroxysmal painful tonic spasms (PPTS) were initially described in multiple sclerosis (MS) but they are more frequent in neuromyelitis optica (NMO). The objective is to report their presence in a series of cases of NMO and NMO spectrum disorders (NMOSD), as well as to determine their frequency and clinical features. We conducted a retrospective assessment of medical histories of NMO/NMOSD patients treated in 2 hospitals in Buenos Aires (Hospital Durand and Hospital Álvarez) between 2009 and 2013. Out of 15 patients with NMOSD (7 with definite NMO and 8 with limited NMO), 4 presented PPTS (26.66%). PPTS frequency in the definite NMO group was 57.14% (4/7). Of the 9 patients with longitudinally extensive transverse myelitis (LETM), 44.44% (9/15) presented PPTS. Mean age was 35 years (range, 22-38 years) and all patients were women. Mean time between NMO diagnosis and PPTS onset was 7 months (range, 1-29 months) and mean time from last relapse of LETM was 30 days (range 23-40 days). LETM (75% cervicothoracic and 25% thoracic) was observed by magnetic resonance imaging (MRI) in all patients. Control over spasms and pain was achieved in all patients with carbamazepine (associated with gabapentin in one case). No favourable responses to pregabalin, gabapentin, or phenytoin were reported. PPTS are frequent in NMO. Mean time of PPTS onset is approximately one month after an LETM relapse, with extensive cervicothoracic lesions appearing on the MRI scan. They show an excellent response to carbamazepine but little or no response to pregabalin and gabapentin. Prospective studies with larger numbers of patients are necessary in order to confirm these results. Copyright © 2014 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U.

To comparatively analyze clinical manifestations in patients with primary esophageal spasm (ES) and its concurrence with gastroesophageal reflux disease (GERD) and the results of their instrumental examinations and psychodiagnostic tests. A total of 104 patients with the clinical and manometric signs of ES were examined and divided into two groups: 1) 42 patients with primary ES; 2) 62 patients with ES concurrent with GERD. The examination encompassed esophageal manometry, esophagogastroduodenoscopy, 24-hour pH metry, and an interview using a questionnaire to identify autonomic disorders, and the Mini-Mult test. The patients with primary ES compared to those with ES concurrent with GERD significantly more frequently showed severe pain syndrome (p = 0.009) and a paradoxical dysphagia pattern (p = 0.03); manometry revealed an incoordination in the motility of the entire esophagus (p = 0.001). Comparison of the statistical series of values for contraction amplitude and duration in the distal esophagus found no significant difference in the patients of both groups. Autonomic disturbances were detected in 76.0% of the patients with ES; but the intergroup differences were insignificant. Mental maladaptation was observed in 81.7% of the patients in the absence of intergroup differences. The etiopathogenetic factor of ES is a psychoautonomic response to chronic stress in both primary ES and its concurrence with GERD. The reflux of gastric contents into the esophagus does not appear to be one of the leading causes of ES. In primary ES, esophageal motor function is generally impaired to a much greater extent than that in ES concurrent with GERD. The degree of motor disorders is embodied in the specific clinical features of the disease.

Spasm of the near reflex (SNR) is a triad of miosis, excess accommodation and excess convergence. Primary SNR is most often functional in origin We aim to highlight the clinical features which distinguish primary convergence from other conditions with a similar presentation but more sinister underlying aetiology, for example bilateral abducens nerve palsy. There is a paucity of published data on SNR, in particular diagnostic criteria and treatment. We report a case of SNR of functional origin in an otherwise healthy young female and discuss the clinical features that differentiate this condition from similar conditions with underlying neurological origin. SNR is predominantly a clinical diagnosis, and often leads to patients undergoing unnecessary investigations and sometimes treatment. Recognising the salient features that differentiate it could potentially avoid this.

To analyze clinical characteristics, treatment and prognosis in a cohort of children with vitamin B6 responsive infantile spasms. Ten patients were diagnosed as vitamin B6 responsive infantile spasms in Peking University First Hospital between January 2012 and May 2015.The clinical manifestations, diagnosis and treatment process, video-electroencephalogram, magnetic resonance imaging (MRI), epilepsy related genes and prognosis were retrospectively analyzed. Of the 10 patients, 5 were male, and 5 were female. Eight of them were normal at birth, and the other 2 patients had intracranial hemorrhage or anoxia.The age of epilepsy onset was from 3.5 to 8.0 months.All patients presented spasms primarily.Interictal electroencephalogram (EEG) showed hypsarrhythmia at seizures onset. MRI showed normal in 8 patients, and subarachnoid hemorrhage or multiple encephalomalacia foci after hemorrhage respectively in the other 2 patients. The results of blood biochemical, cerebrospinal fluid examination and urinary metabolic screening were negative. Epilepsy related genes including ALDH7A1 gene analysis showed wild type in all patients. Two patients were classified as symptomatic and eight might be idiopathic or cryptogenic. The initial dose of vitamin B6 was 10.0 mg/(kg·d). The interval between seizures onset and taking vitamin B6 was 0 to 4.0 months. Seizures disappeared completely within a week after administration of vitamin B6 in 9 patients and in 1.5 months in one patient.Of the 8 patients whose seizures were controlled completely during the follow-up period, 7 patients' EEG recovered within 1.5 to 4.0 months and then continued to be normal. The EEG of the rest of a patient returned to normal, but showed abnormal discharges after stopping taking vitamin B6. Two patients' EEG continued abnormal and seizures recurred due to vitamin B6 withdrawal. At the last follow-up, seizures were controlled in all patients. Drug treatment in one case had stopped. Vitamin B6 was used in 9

To determine the performance of an artificial neural network in transcranial color-coded duplex sonography (TCCS) diagnosis of middle cerebral artery (MCA) spasm. TCCS was prospectively acquired within 2 h prior to routine cerebral angiography in 100 consecutive patients (54M:46F, median age 50 years). Angiographic MCA vasospasm was classified as mild (<25% of vessel caliber reduction), moderate (25-50%), or severe (>50%). A Learning Vector Quantization neural network classified MCA spasm based on TCCS peak-systolic, mean, and end-diastolic velocity data. During a four-class discrimination task, accurate classification by the network ranged from 64.9% to 72.3%, depending on the number of neurons in the Kohonen layer. Accurate classification of vasospasm ranged from 79.6% to 87.6%, with an accuracy of 84.7% to 92.1% for the detection of moderate-to-severe vasospasm. An artificial neural network may increase the accuracy of TCCS in diagnosis of MCA spasm.

Hemifacial microsomia is a hypoplastic disorder of the first and second branchial arches that significantly impacts on the development of the jaws, leading to malocclusion and facial asymmetry. There is little in the literature regarding the application of orthodontic/orthognathic approaches to the correction of these deformities and the stability of the surgical results. To address this, a retrospective chart review of 10 patients with complete orthodontic records and greater than 1 year of follow-up was performed. Posteroanterior cephalograms were assessed by modified Grummons analysis to determine mandibular offset (deviation of the chin point from the skeletal midline) and occlusal cant. These measurements were performed at 3 time points (T1: preoperative, T2: immediate postoperative, T3: follow-up) to elucidate the surgical movement (T2-T1), the postoperative relapse (T3-T2), and the net gain movement (T3-T1). Maxillary movements were quantified, and the occlusal cant was expressed as a ratio between vertical heights of the maxilla at the first molar on each side. One sample t test demonstrated statistically significant surgical movement and net gain. Relapse was statistically insignificant. Repeated-measures analysis of variance demonstrated similar results for chin point position relative to the putative midline. Our results suggest that a combined orthodontic/orthognathic approach at skeletal maturity delivers improved occlusal outcomes in the long term as assessed by chin point deviation and occlusal cant, but secondary surgery rates are higher than those for orthognathic surgery in other patient groups. We advocate limiting surgery to skeletal maturity whenever possible to achieve stable long-term results while limiting morbidity and number of procedures.

A 50-year-old male patient was scheduled for left partial pulmonary resection and biopsy. The patient had neither complication nor history of ischemic heart disease. After arriving in the operation room, an epidural catheter was inserted into the epidural space at the T 4-5 intervertebral space. Anesthesia was induced with intravenous propofol 100 mg, fentanyl 100 microgram and vecuronium 6 mg and then a double lumen endotracheal tube was inserted. Anesthesia was maintained with O2 and air (FIO2 0.3-1.0), continuous infusion of propofol, intermittent intravenous administration of fentanyl and epidural injection of 1% lidocaine. Forty-five minutes after the start of operation, ECG showed an elevation of ST segment and soon it passed into ventricular tachycardia and ventricular fibrillation. The patient was treated with cardiopulmonary resuscitation. Fifteen minutes later, ECG returned to sinus rhythm but the elevation of ST segment remained. We considered that these cardiac events were due to coronary spasm, and started continuous infusion of nitroglycerin and nicorandil. One hour later, ST segment returned to normal. The possible inducing factors in this case were altered balance between sympathetic and parasympathetic nervous activity caused by infusion of propofol and epidural block, and alpha-stimulation caused by ephedrine.

Spasm of the near reflex: a spectrum of anomalies.

PubMed

Goldstein, J H; Schneekloth, B B

1996-01-01

Spasm of the near reflex has been characterized as the variable appearance of pseudomyopia, convergent strabismus and miosis. These characteristics may appear together or separately. In addition, abnormalities of accommodation may appear not only as pseudomyopia, but may also be manifest in cases with significant hypermetropia in which the patient is unable to relax accommodation even when plus lenses are used. The intent of this review is to identify the various clinical presentations of anomalies of the entire near reflex as well as the component parts. The relationship to functional and organic disorders are discussed as well as the related neuroanatomy. We suggest that one may more readily understand the clinical manifestations as a spectrum of anomalies of the near reflex rather than a multitude of disconnected entities.

We describe the clinical features, investigations and outcome of 4 adolescents aged 13, 16, 17 and 19 years, with fixed dystonia. The diagnosis was made within 6 months of the onset of symptoms. One patient had an identifiable traumatic precipitant. All the affected extremities had pain, sudomotor and vascular changes which were consistent with complex regional pain syndrome. The extremities affected by dystonia were the foot and the hand. The dystonia spread to affect other extremities in one patient. One patient had hemifacial spasm. Examination of the central and peripheral nervous system and allied investigations failed to reveal an organic cause. Common genetic causes for dystonia were excluded. The response to physical treatments for the affected extremities, such as Botulinum Toxin and surgery was poor. In all our cases there were significant psychological and psychiatric factors. Three patients fully met the criteria for psychogenic dystonia and responded well to psychological intervention. Fixed dystonia in adolescents is an uncommon disorder of unknown aetiology, usually presenting in girls, which can be very disabling and difficult to treat. The affected parts of the body are usually painful and show vascular changes. The condition is allied to CRPS. Treatment with multidisciplinary approach including psychological measures and physiotherapy is more likely to be successful and may prevent unnecessary physical measures.

Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension. Blood pressure returned to normal after gelofusine infusion; no sympathomimetics were administered. The male denied chest pain; however, ECG showed ST segment elevation coexisting with left ventricular anterolateral hypokinesia and decreased longitudinal strain in echocardiography. A significant increase in troponin I level was suggestive rather of myocardial infarction than of takotsubo cardiomyopathy. Urgent coronary angiography revealed left anterior descending artery spasm, which remitted after intracoronary nitroglycerin injection. Normalization of ECG and echocardiography was observed within a few days. The authors indicate that the presented atypical adverse effect of bupivacaine manifested itself with delay and that coronary spasm proceeded without angina. A close observation of the patient after anesthetic procedure with LA should be extended over the postoperative period.

Hemifacial microsomia is a deformity of variable expressivity with unilateral hypoplasia of the mandible and the ear. In this study, we evaluated skeletal soft tissue changes after bimaxillary unilateral vertical distraction. Eight patients (4 preadolescents 4 adolescents) each with a grade II mandibular deformity underwent a LeFort I osteotomy and an ipsilateral horizontal mandibular ramus osteotomy. A semiburied distraction device was placed over the ramus, and intermaxillary fixation was applied. Anteroposterior cephalometric and frontal photographic analyses were conducted before and after distraction. Statistics were used to analyze the preoperative and postoperative changes. Cephalometrically, the nasal floor and the occlusal and gonial plane angles decreased. The ratios of affected-unaffected ramus and gonial angle heights improved by 15% and 20%, respectively. The position of menton moved toward the midline. The photographic analysis showed a decrease of the nasal and commissure plane angles, and the chin moved to the unaffected side. The parallelism between the horizontal skeletal and soft tissue planes improved, with an increase in the affected side ramus height and correction of the chin point toward the midline. Simultaneous maxillary and mandibular distraction improved facial balance and symmetry. Patients in the permanent dentition with fixed orthodontic appliances and well-aligned dental arches responded well to this intervention. Copyright © 2015 American Association of Orthodontists.

To analyze the effect of mandibular distraction on the maxilla growth in children with hemifacial microsomia through measurement with the posterior-anterior cephalometric X-ray films and Three-dimensional CT reconstruction images. The deviation angular of maxilla occlusion plane and nasal base plane from the infra-orbital plane were measured on the posterior-anterior cephalometric X-ray films in 22 patients before and half a year after operation. The vertical distance from the midpoint of 5th teeth alveolar and the lowest point of maxillary sinus to reference plane were measured on 3D reconstruction images in 15 patients. The data were statistically analyzed. On posterior-anterior cephalometric X-ray films, the cant of occlusion plane were significantly reduced (P < 0.05), While the angular of nasal base plane and the infra-orbital plane had no significant change. On 3D reconstruction images, all the detection points had significantly declined except the lowest point of maxillary sinus on normal side. Distraction osteogenesis of mandible can promote the growth of the maxilla in children with HFM, the accelerated growth parts include alveolar bone and maxillary sinus.

The effect of vasodilatory medications on radial artery spasm in patients undergoing transradial coronary artery procedures: a systematic review.

The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications. The objective of this study is to identify the effectiveness of vasodilatory medications on radial artery spasm in patients undergoing transradial coronary artery procedures. This review considered studies that included participants aged 18 years and over undergoing non-emergent transradial percutaneous coronary artery procedures. This review considered studies that used vasodilating intravenous and intra-arterial medications or combinations of medications prior to commencing and during transradial coronary approaches to reduce radial artery spasm. The outcomes of interest were the incidence of radial artery spasm during percutaneous coronary procedure using objective and/or subjective measures and its effect on the successful completion of the procedure. Randomized controlled trials published in the English language between 1989 to date were considered for inclusion. The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in this review. An initial search of MEDLINE, CINAHL and Scopus was undertaken, followed by a search for unpublished studies. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments. Any disagreements that arose between the reviewers were resolved through discussion. Quantitative data was extracted from papers included in the review using the

Radical S -adenosylmethionine (SAM) enzymes are emerging as a major superfamily of biological catalysts involved in the biosynthesis of the broad family of bioactive peptides called ribosomally synthesized and post-translationally modified peptides (RiPPs). These enzymes have been shown to catalyze unconventional reactions, such as methyl transfer to electrophilic carbon atoms, sulfur to C α atom thioether bonds, or carbon-carbon bond formation. Recently, a novel radical SAM enzyme catalyzing the formation of a lysine-tryptophan bond has been identified in Streptococcus thermophilus , and a reaction mechanism has been proposed. By combining site-directed mutagenesis, biochemical assays, and spectroscopic analyses, we show here that this enzyme, belonging to the emerging family of SPASM domain radical SAM enzymes, likely contains three [4Fe-4S] clusters. Notably, our data support that the seven conserved cysteine residues, present within the SPASM domain, are critical for enzyme activity. In addition, we uncovered the minimum substrate requirements and demonstrate that KW cyclic peptides are more widespread than anticipated, notably in pathogenic bacteria. Finally, we show a strict specificity of the enzyme for lysine and tryptophan residues and the dependence of an eight-amino acid leader peptide for activity. Altogether, our study suggests novel mechanistic links among SPASM domain radical SAM enzymes and supports the involvement of non-cysteinyl ligands in the coordination of auxiliary clusters. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

The increases in capillary wall permeability and capillary hydrostatic pressure are considered to be the causes for the acute swelling seen in flaps; however, disruption of the circulating flap lymphatics could be another contributory factor. In this study we monitor the development of flap edema in a series of 18 prefabricated flaps and aim to delineate the natural history of this phenomenon by use of lymphography. Postoperative swelling was monitored in a series of 18 pre-expanded prefabricated cervical skin flaps used for hemi-facial burns-scar resurfacing. Time to spontaneous resolution, presence or absence of venous congestion, and clinical outcome were recorded. In two cases, indocyanine-green (ICG) lymphography was used to monitor the dermal backflow pattern until swelling had completely resolved. Average moving velocity of ICG after injection as well as flap thickness was also recorded over the follow-up period. The average moving velocity of ICG in the flap lymphatics improved from 0.48 cm/min to 1.5 cm/min in the first 12 days after flap transfer. The dermal backflow pattern was stardust in the first 12 days, indicating moderate lymphedema, transforming to splash from week three, and a robust collecting lymphatic vessel occurring from the fifth month, indicating mild lymphedema and lymphatic channel recovery, respectively. Transient swelling was observed in all prefabricated flaps in our series. We postulate that this is mostly secondary to lymphatic disruption that subsides as lymphangiogenesis takes place. ICG lymphography is an inexpensive, safe, and easy-to-use imaging technology that could be used in the monitoring of postoperative lymphedema seen in prefabricated flaps.

Intramuscular Neurotrophin-3 normalizes low threshold spinal reflexes, reduces spasms and improves mobility after bilateral corticospinal tract injury in rats.

Brain and spinal injury reduce mobility and often impair sensorimotor processing in the spinal cord leading to spasticity. Here, we establish that complete transection of corticospinal pathways in the pyramids impairs locomotion and leads to increased spasms and excessive mono- and polysynaptic low threshold spinal reflexes in rats. Treatment of affected forelimb muscles with an adeno-associated viral vector (AAV) encoding human Neurotrophin-3 at a clinically-feasible time-point after injury reduced spasticity. Neurotrophin-3 normalized the short latency Hoffmann reflex to a treated hand muscle as well as low threshold polysynaptic spinal reflexes involving afferents from other treated muscles. Neurotrophin-3 also enhanced locomotor recovery. Furthermore, the balance of inhibitory and excitatory boutons in the spinal cord and the level of an ion co-transporter in motor neuron membranes required for normal reflexes were normalized. Our findings pave the way for Neurotrophin-3 as a therapy that treats the underlying causes of spasticity and not only its symptoms.

Spinal cord stimulation to abort painful spasms of atypical stiff limb syndrome.

Stiff limb syndrome (SLS) is a rare chronic condition which can result in significant debility. We report the case of a 44-year-old man suffering from severe painful spasms in his right leg with a diagnosis of SLS. He had been initially treated for his pain with a spinal cord stimulator but presented with exacerbation of pain secondary to a lead fracture for which he underwent revision of the stimulator. Postoperative programming unexpectedly resulted in not only control of his pain but also an ability to abort his spasmodic episodes related to SLS. To our knowledge, spinal cord stimulation has not been previously used for SLS and our report opens up another avenue for this rare condition. We provide a brief overview of SLS and propose an underlying mechanism for the observed phenomenon.

The success of transradial catheterization depends on meticulous access of radial artery which in turn depends on palpating a good radial pulse. Our objectives were to analyze the effects of subcutaneously infiltrated nitroglycerin on diameter of radial artery, palpability of radial pulse, ease-of-puncture and pre-cannulation spasm of radial artery during transradial coronary angiography. Patients undergoing transradial coronary angiography were randomized to Group NL or Group SL. In Group NL, 3 ml of solution containing nitroglycerin and lignocaine was infiltrated subcutaneously at the site intended for puncture of radial artery. Similarly, saline and lignocaine were infiltrated in Group SL. Diameter of radial artery was objectively assessed by ultrasonography. Measurements were performed at baseline and repeated at 1 min after injecting the solutions. The ease-of-puncture was evaluated by the number of punctures and the time needed for successful access of radial artery. Both groups had 100 patients each. Baseline diameter of radial artery was similar between two groups. The post-injection diameter of radial artery increased by 26.3% in Group NL and 11.4% in Group SL. Nitroglycerin significantly improved the palpability of radial pulse, reduced the number of punctures and shortened the time needed for successful access of radial artery. Pre-cannulation spasm of radial artery occurred in 1% of Group NL and 8% of Group SL. Subcutaneously infiltrated nitroglycerin leads to significant vasodilation of radial artery. This avoids pre-cannulation spasm of radial artery, enhances palpability of the radial pulse and thus makes the puncture of radial artery easier. Copyright © 2014 Cardiological Society of India.

Several reports have suggested that thyrotoxicosis may induce severe coronary artery spasm (CAS). However, there are few data regarding the differences in clinical characteristics of CAS with and without thyrotoxicosis. The aim of our study is to compare the clinical features of CAS with and without thyrotoxicosis. We evaluated 430 consecutive patients with CAS [patients with thyrotoxicosis (N=32, group I) and those without (N=398, group II)] at a single institute between January 2001 and June 2011. We compared clinical presentations, angiographic findings, and adverse outcomes (a composite outcome of cardiac death, myocardial infarction, or rehospitalization due to cardiac cause) of both groups. There was higher incidence of acute myocardial infarction at initial presentation in group I (15.6 vs. 5.8%, P=0.04). CAS with thyrotoxicosis was more diffuse (59.4 vs. 39.3%, P=0.03), more medically intractable (9.4 vs. 0%, P=0.001), and more frequently involved the left main vessel (25.0 vs.0.8%, P=0.001) than CAS without thyrotoxicosis. During the follow-up period (median 43 months), there were no significant differences between the two groups in terms of the risk of adverse outcomes (hazard ratio for CAS with thyrotoxicosis, 1.029; 95% confidence interval, 0.347-3.054). Clinical and angiographic presentations of CAS with thyrotoxicosis were more severe than CAS without thyrotoxicosis, but clinical outcomes were similar in both groups. Optimal vasodilator therapy is essential for the management of CAS with thyrotoxicosis. Thyroid function test should be mandatory for all patients with CAS.

A multicenter open-label clinical trial was conducted to evaluate the clinical usefulness of topiramate (TPM) as primary or adjunctive therapy for infantile spasms in the postmarketing period in China. Thirty-four centers participated in the trial. Patients included in the study had 1 or more seizures per day before treatment. One hundred twenty (22.1%) very young patients with an age younger than 6 month and 64.2% of patients were younger than 1 year at start of treatment. All patients received a starting dose of 0.5 to 1 mg kg d TPM twice daily. The dosage was increased by 0.5 to 1 mg kg d every 5 to 7 days up to 3 to 5 mg kg d. The resulting range of the total TPM dosage was 25 to 200 mg d (3.57-20 mg kg d), with a median value of 73.9 mg d. Seizure outcomes were measured by intention-to-treat analysis. Patients were seen by a neurologist, and their data were evaluated at the day of inclusion and after 4, 8, 12, 16, and 20 weeks (from visit 1 to visit 5) of treatment. Five hundred forty-four patients entered the study. After 20 weeks of TPM treatment, 239 patients (43.9%) were seizure-free. A higher proportion of patients in the monotherapy group than in the add-on therapy group showed a seizure rate reduction. An increase in seizure frequency was observed in 8 patients (1.5%) during the 20-week treatment period. Nineteen patients were withdrawn before completing the study, and in 46 cases, some data of the structured data files and questionnaires were missing. No efficacy of TPM treatment was recorded in these cases. Adverse effects occurred in 211 patients (38.8%). Most frequent side effects were anorexia and somnolence. Topiramate proved to be an effective and safe monotherapy and add-on therapy in patients with infantile spasms younger than 1 year.

To research the possibility of designing customized 3D printing fingerboard to apply to the limb rehabilitation of cerebral stroke patients as well as the prevention and treatment of finger spasm, through 3D printing technology. Taking 18 hospitalized cerebral stroke patients for example, through scanning, molding and printing, to make and wear 3D printing fingerboard for them, and then observe the compliance, main complaint, muscular tension of affected hand and changes on range of motion after they wear the fingerboard for 3 weeks and 3 months. Have acquired completed data from 13 patients. The time of them wearing the fingerboard every day varied from 1 to 8 h, and most of them reflected that they felt comfortable and there was no feeling of worsened pain or finger skin allergy. In addition, the patients' grip strength, hand function and range of motion improved by varying degrees while their muscular tensions declined by varying degrees. The tension and bending resistance of the fingerboard all met the patients' treatment requirements.

Brain and spinal injury reduce mobility and often impair sensorimotor processing in the spinal cord leading to spasticity. Here, we establish that complete transection of corticospinal pathways in the pyramids impairs locomotion and leads to increased spasms and excessive mono- and polysynaptic low threshold spinal reflexes in rats. Treatment of affected forelimb muscles with an adeno-associated viral vector (AAV) encoding human Neurotrophin-3 at a clinically-feasible time-point after injury reduced spasticity. Neurotrophin-3 normalized the short latency Hoffmann reflex to a treated hand muscle as well as low threshold polysynaptic spinal reflexes involving afferents from other treated muscles. Neurotrophin-3 also enhanced locomotor recovery. Furthermore, the balance of inhibitory and excitatory boutons in the spinal cord and the level of an ion co-transporter in motor neuron membranes required for normal reflexes were normalized. Our findings pave the way for Neurotrophin-3 as a therapy that treats the underlying causes of spasticity and not only its symptoms. DOI: http://dx.doi.org/10.7554/eLife.18146.001 PMID:27759565

A 38-year-old man visited our hospital because of hemifacial paresis that developed 2 months after being bit by a tick. We diagnosed idiopathic peripheral facial palsy and gave the patient oral prednisolone and valacyclovir. Although the symptoms completely resolved in about 2 weeks, there was a risk of Lyme neuroborreliosis. The patient therefore received doxycycline (100 mg twice daily) and amoxicillin (1,000 mg 3 times daily) for 14 days. Two months later, he had symptoms of meningitis such as headache and fever accompanied by lymphocytic cerebrospinal fluid pleocytosis. Viral meningitis was diagnosed and treated with parenteral acyclovir. The symptoms of meningitis improved. Tests for serum IgG antibodies against borrelia were positive. We gave the patient a diagnosis of Lyme neuroborreliosis. The patient received intravenous ceftriaxone and had no relapse. It is a rare for meningitis to develop in a patient with cranial neuropathy who received doxycycline. Lyme neuroborreliosis is a rare disease in Japan. Care should therefore be exercised in the diagnosis of Lyme neuroborreliosis and evaluation of the response to treatment.

An infant presented with global developmental delay and infantile spasms. EEG was suggestive of hypsarrhythmia. She was started on sodium valproate, clonazepam and adrenocorticotropic hormone injection. After an initial improvement the child developed vomiting, altered sensorium and increase in frequency of seizures suggestive of encephalopathy. Valproate-induced hyperammonaemia or hepatic encephalopathy was considered and the drug was withheld following which there was a dramatic improvement. Paradoxically, the liver function tests and serum ammonia were normal. However, a complete reversal of encephalopathy, on withdrawal of the drug, strongly suggested an adverse drug reaction (ADR) due to valproic acid. Marginal elevation of serum valproic acid prompted us to use the Naranjo ADR probability score to confirm the diagnosis. This case highlights the fact that valproate toxicity can manifest with normal liver function and serum ammonia levels. This is the youngest reported case with this rare form of valproate-induced encephalopathy. PMID:24810446

We aimed to investigate the relationship between movement disorders, changes on brain magnetic resonance imaging (MRI), and vigabatrin therapy in children with infantile spasms. Retrospective review and brain MRI analysis of children enrolled in the International Collaborative Infantile Spasms Study (ICISS) who developed a movement disorder on vigabatrin therapy. Comparisons were made with controls within ICISS who had no movement disorder. Ten of 124 infants had a movement disorder and in eight it had developed on vigabatrin therapy. Two had a movement disorder that resolved on dose-reduction of vigabatrin, one had improvement on withdrawing vigabatrin, two had resolution without any dose change, and in three it persisted despite vigabatrin withdrawal. The typical brain MRI changes associated with vigabatrin therapy were noted in two infants. Ten control infants were identified. Typical MRI changes noted with vigabatrin were noted in three controls. It is possible that in two out of eight cases, vigabatrin was associated with the development of a movement disorder. In six out of eight cases a causal relationship was less plausible. The majority of infants treated with vigabatrin did not develop a movement disorder. MRI changes associated with vigabatrin do not appear to be specifically related to the movement disorder. © 2013 Mac Keith Press.

Focal status epilepticus and catastrophic epilepsy are not rare in infants. Epilepsy surgery can be safely done in selected infants to cure epilepsy. We report on an infant who began having drug-resistant status epilepticus at 2 weeks of age and developed epileptic spasms. We discuss in detail how the clinical and electroencephalographic data were used to reach a consensus for epilepsy surgery and why a particular surgical approach was preferred over other alternatives. Presurgical evaluation consisted of 32-channel scalp video EEG using the standard 10-20 system of electrodes, 3-Tesla brain magnetic resonance imaging, and 18 F-fluorodeoxyglucose positron emission tomography. The surgery consisted of resection of the extensive epileptogenic lesion, in addition to disconnection of the left frontal lobe anterior to the motor strip. The infant underwent epilepsy surgery at three months of age. At two-year follow up, she remained seizure free, with no focal motor deficit and the epileptic encephalopathy resolved. The disconnected left frontal lobe shows epileptiform discharges restricted to the disconnected tissue. We highlight the importance of epilepsy surgery in selected infants to achieve seizure freedom and to reverse epileptic encephalopathy. In the process, we demonstrate how epileptic spasms, although clinically and electrographically generalized, resolved after disconnecting the epileptogenic zone.

Constitutively active 5-HT2/α1 receptors facilitate muscle spasms after human spinal cord injury

In animals, the recovery of motoneuron excitability in the months following a complete spinal cord injury is mediated, in part, by increases in constitutive serotonin (5-HT2) and norepinephrine (α1) receptor activity, which facilitates the reactivation of calcium-mediated persistent inward currents (CaPICs) without the ligands serotonin and norepinephrine below the injury. In this study we sought evidence for a similar role of constitutive monoamine receptor activity in the development of spasticity in human spinal cord injury. In chronically injured participants with partially preserved sensory and motor function, the serotonin reuptake inhibitor citalopram facilitated long-lasting reflex responses (spasms) previously shown to be mediated by CaPICs, suggesting that in incomplete spinal cord injury, functional descending sources of monoamines are present to activate monoamine receptors below the lesion. However, in participants with motor or motor/sensory complete injuries, the inverse agonist cyproheptadine, which blocks both ligand and constitutive 5-HT2/α1 receptor activity, decreased long-lasting reflexes, whereas the neutral antagonist chlorpromazine, which only blocks ligand activation of these receptors, had no effect. When tested in noninjured control participants having functional descending sources of monoamines, chlorpromazine was effective in reducing CaPIC-mediated motor unit activity. On the basis of these combined results, it appears that in severe spinal cord injury, facilitation of persistent inward currents and muscle spasms is mainly mediated by the activation of constitutive 5-HT2 and α1 receptor activity. Drugs that more selectively block these constitutively active monoamine receptors may provide better oral control of spasticity, especially in motor complete spinal cord injury where reducing motoneuron excitability is the primary goal.

Mechanisms of epileptogenesis in pediatric epileptic syndromes: Rasmussen encephalitis, infantile spasms, and febrile infection-related epilepsy syndrome (FIRES).

2014-04-01

The mechanisms of epileptogenesis in pediatric epileptic syndromes are diverse, and may involve disturbances of neurodevelopmental trajectories, synaptic homeostasis, and cortical connectivity, which may occur during brain development, early infancy, or childhood. Although genetic or structural/metabolic factors are frequently associated with age-specific epileptic syndromes, such as infantile spasms and West syndrome, other syndromes may be determined by the effect of immunopathogenic mechanisms or energy-dependent processes in response to environmental challenges, such as infections or fever in normally-developed children during early or late childhood. Immune-mediated mechanisms have been suggested in selected pediatric epileptic syndromes in which acute and rapidly progressive encephalopathies preceded by fever and/or infections, such as febrile infection-related epilepsy syndrome, or in chronic progressive encephalopathies, such as Rasmussen encephalitis. A definite involvement of adaptive and innate immune mechanisms driven by cytotoxic CD8(+) T lymphocytes and neuroglial responses has been demonstrated in Rasmussen encephalitis, although the triggering factor of these responses remains unknown. Although the beneficial response to steroids and adrenocorticotropic hormone of infantile spasms, or preceding fever or infection in FIRES, may support a potential role of neuroinflammation as pathogenic factor, no definite demonstration of such involvement has been achieved, and genetic or metabolic factors are suspected. A major challenge for the future is discovering pathogenic mechanisms and etiological factors that facilitate the introduction of novel targets for drug intervention aimed at interfering with the disease mechanisms, therefore providing putative disease-modifying treatments in these pediatric epileptic syndromes.

Diffuse esophageal spasm: has the term lost its relevance? Analysis of 217 cases.

Tsuboi, K; Mittal, S K

Diffuse esophageal spasm (DES) has been reported as a potential cause of dysphagia or chest pain; however, the patho-physiology of DES is unclear. The aim of this study was to examine the manometric correlates of dysphagia and chest pain in this patient population. All patients undergoing manometry at our institution are entered into a prospectively maintained database. After institutional review board approval, the database was queried to identify patients meeting criteria for DES (≥20% simultaneous waves with greater than 30 mm Hg pressure in the distal esophagus). The patient-reported symptoms and manometric data, along with the results of a 24-hour pH study (if done), were extracted for further analysis. Out of 4923 patients, 240 (4.9%) met the manometric criteria for DES. Of these, 217 patients had complete manometry data along with at least one reported symptom. Of the patients with DES, 159 (73.3%) had dysphagia or chest pain as a reported symptom. Patients reporting either dysphagia or chest pain had significantly higher lower esophageal sphincter (LES) pressure than patients without these symptoms (P= 0.007). Significant association was noted between reported dysphagia and percentage of simultaneous waves. Chest pain did not correlate with percent of simultaneous waves, mean amplitude of peristalsis, or 24-hour pH score. The origin of reported chest pain in patients with DES is not clear but may be related to higher LES pressure. Simultaneous waves were associated with reported dysphagia. Using current diagnostic criteria, the term DES has no clinical relevance. © 2010 Copyright the Authors.

Radial artery spasm (RAS) is the most common complication in transradial coronary angiography and intervention. In this study, we designed to investigate the incidence of RAS during transradial procedures in Chinese, find out the independent predictors through multiple regression, and analyze the clinical effect of RAS during follow-up. Patients arranged to receive transradial coronary angiography and intervention were consecutively enrolled. The incidence of RAS was recorded. Univariate analysis was performed to find out the influence factors of RAS, and logistic regression analysis was performed to find out the independent predictors of RAS. The patients were asked to return 1 month later for the assessment of the radial access. The incidence of RAS was 7.8% (112/1427) in all the patients received transradial procedure. Univariate analysis indicates that young (P = 0.038), female (P = 0.026), small diameter of radial artery (P < 0.001), diabetes (P = 0.026), smoking (P = 0.019), moderate or severe pain during radial artery cannulation (P < 0.001), unsuccessful access at first attempt (P = 0.002), big sheath (P = 0.004), number of catheters (> 3) (P = 0.048), rapid baseline heart rate (P = 0.032) and long operation time (P = 0.021) were associated with RAS. Logistic regression showed that female (OR = 1.745, 95%CI: 1.148 - 3.846, P = 0.024), small radial artery diameter (OR = 4.028, 95%CI: 1.264 - 12.196, P = 0.008), diabetes (OR = 2.148, 95%CI: 1.579 - 7.458, P = 0.019) and unsuccessful access at first attempt (OR = 1.468, 95%CI: 1.212 - 2.591, P = 0.032) were independent predictors of RAS. Follow-up at (28 +/- 7) days after the procedure showed that, compared with non-spasm patients, the RAS patients had higher portion of pain (11.8% vs. 6.2%, P = 0.043). The occurrences of hematoma (7.3% vs. 5.6%, P = 0.518) and radial artery occlusion (3.6% vs. 2.6%, P = 0.534) were similar. The incidence of RAS during transradial coronary procedure was 7.8%.

Advanced and standardized evaluation of neurovascular compression syndromes

Caused by a contact between vascular structures and the root entry or exit zone of cranial nerves neurovascular compression syndromes are combined with different neurological diseases (trigeminal neurolagia, hemifacial spasm, vertigo, glossopharyngeal neuralgia) and show a relation with essential arterial hypertension. As presented previously, the semi-automatic segmentation and 3D visualization of strongly T2 weighted MR volumes has proven to be an effective strategy for a better spatial understanding prior to operative microvascular decompression. After explicit segmentation of coarse structures, the tiny target nerves and vessels contained in the area of cerebrospinal fluid are segmented implicitly using direct volume rendering. However, based on this strategy the delineation of vessels in the vicinity of the brainstem and those at the border of the segmented CSF subvolume are critical. Therefore, we suggest registration with MR angiography and introduce consecutive fusion after semi-automatic labeling of the vascular information. Additionally, we present an approach of automatic 3D visualization and video generation based on predefined flight paths. Thereby, a standardized evaluation of the fused image data is supported and the visualization results are optimally prepared for intraoperative application. Overall, our new strategy contributes to a significantly improved 3D representation and evaluation of vascular compression syndromes. Its value for diagnosis and surgery is demonstrated with various clinical examples.

There are few reports on hemiparesis caused by vascular medullary compression, which can occur because of dolichoectasia of the vertebrobasilar arterial system. In this article, we report a case of vertebral artery compression of the medulla oblongata in a 67-year-old woman. The patient was hypertensive, and she developed hemiparesis and intermittent spasms over 5 years. These spasms had worsened during the last year. Cranial nerve magnetic resonance imaging showed compression of the medulla oblongata by the left vertebral artery. A motor evoked potential (MEP) examination showed abnormal conduction of MEPs of bilateral toe abductors. The patient underwent microvascular decompression surgery under general anesthesia through a retrosigmoid keyhole approach. This operation led to relief of vascular compression and symptomatic improvement. Our case suggests that detailed history, imaging studies, and electrophysiologic studies help lead to a correct and early diagnosis of hemiparesis caused by vascular compression of the rostral ventrolateral medulla. Microvascular decompression surgery improves patient symptoms, and intraoperative electrophysiologic monitoring helps to avoid injury to important adjacent nerves. Copyright © 2017 Elsevier Inc.

The goal of this study was to describe the clinical characteristics and treatment outcomes of patients with hemifacial microsomia (HFM) and cleft lip/palate (CL/P), and to compare them to a historic cohort of patients with non-syndromic CL/P treated at the same centre. A retrospective review of patients with HFM and CL/P was performed; the main outcome measures assessed were cleft type/side, surgical outcome, midfacial retrusion, and speech. Twenty-six patients (13 male, 13 female; mean age 22.7±14.9, range 1-52 years) with cleft lip with/without cleft palate (CL±P) were identified: three with cleft lip (12%), two with cleft lip and alveolus and an intact secondary palate (8%), and 21 with cleft lip and palate (CLP) (81%; 15 unilateral and six bilateral). Four patients (19%) had a palatal fistula after palatoplasty. Twelve of 22 patients aged >5 years (55%) had midfacial retrusion and two (9%) required a pharyngeal flap for velopharyngeal insufficiency (VPI). Fisher's exact test demonstrated a higher frequency of complete labial clefting (P=0.004), CLP (P=0.009), midfacial retrusion (P=0.0009), and postoperative palatal fistula (P=0.03) in HFM compared to non-syndromic CL±P. There was no difference in VPI prevalence. This study revealed that patients with HFM and CL±P have more severe forms of orofacial clefting than patients with non-syndromic CL±P. Patients with HFM and CL±P have more severe midfacial retrusion and a higher palatal fistula rate compared to patients with non-syndromic CL±P.

We describe the case of an eight-year-old girl with complaints of headaches and blurred vision (uncorrected visual acuity: 0.1 decimal) that showed on examination miotic pupils, pseudomyopia, no ocular motility restrictions, and no associated neurological disease. After initial treatment with cyclopentolate for two months, pseudomyopia persisted with an intermittent and variable esotropia. Spectacles of +1 both eyes and atropine 1% one drop daily were then prescribed. The situation improved and remained stable for several weeks, with pseudomyopia and esotropia reappearing later. Finally, botulinum toxin (2.5 iu Botox) was injected in the medial rectus muscle on two occasions and a visual therapy program based on the stimulation of fusional divergence, diplopia, and stereopsis consciousness was recommended. This prescription was combined with the use of atropine during the first few weeks. Orthotropia and corrected distance visual acuity of 1.0 were found three months after treatment. The evolution and clinical results of this case report suggest that botulinum toxin in combination with other therapeutic alternatives may be useful in the treatment of spasm of the near reflex.

Mutations in the human X-linked cyclin-dependent kinase-like 5 (CDKL5) gene have been shown to cause infantile spasms as well as Rett syndrome-like phenotype. To date, fewer than 20 different mutations have been reported. So far, no clear genotype-phenotype correlation has been established. We screened the entire coding region of CDKL5 in 151 affected girls with a clinically heterogeneous phenotype ranging from encephalopathy with epilepsy to atypical Rett syndrome by denaturing high liquid performance chromatography and direct sequencing, and we identified three novel missense mutations located in catalytic domain (p.Ala40Val, p.Arg65Gln, p.Leu220Pro). Segregation analysis showed that p.Arg65Gln was inherited from the healthy father, which rules out the involvement of CDKL5 in the aetiology of the phenotype in this patient. However, the de novo occurrence was shown for p.Ala40Val and p.Leu220Pro. The p.Ala40Val mutation was observed in two unrelated patients and represented the first recurrent mutation in the CDKL5 gene. For the two de novo mutations, we analysed the cellular localisation of the wild-type and CDKL5 mutants by transfection experiments. We showed that the two CDKL5 mutations cause mislocalisation of the mutant CDKL5 proteins in the cytoplasm. Interestingly these missense mutations that result in a mislocalisation of the CDKL5 protein are associated with severe developmental delay which was apparent within the first months of life characterised by early and generalised hypotonia, and autistic features, and as well as early infantile spasms.

Introduction: Myocardial bridge is an inborn anomaly of coronary artery development, when a part of it is submerged in a myocard, which is pressing the coronary artery to a systola and restrains coronary blood circulation. Generally this feature of coronary blood circulation does not cause any clinical symptoms because the 85% of coronary blood stream of the left ventricle is provided by diastolic filling. Hemodynamic changes in atherosclerosis, tahicardie, hypertrophie of myocard are leading to the manifestation of clinical symptoms of ischemia. The aim: The purpose of the investigation was to discover the features of clinical development of acute coronary syndrome caused by myocardial bridge of young patients without the features of atherosclerotical harm of coronary arteries. Materials and methods: Eight causes of acute coronary syndrome among patients of 28±8,5 years with myocardial bridge which was revealed during coronary angiography, were investigated. Standardized examination and conservative treatment of patients was held, except for three who have got interventional therapy. Results: According to our investigation, myocardial bridge of all investigated patients was located in the middle of the third front interventricular branch of the left coronary artery. Causes of acute coronary syndrome manifestation were tahicardia, spasms of coronary artery, inducted by iatrogenic factors hypertrophie of myocard, hypertrophic cardiomyopatie. Connection between the manifestation of clinical symptoms and length of tunneled segment which did not depend on the level of systolic compres was discovered. The results of conservative and interventional treatment were analyzed. Conclusions: Myocardial bridge can be the cause of myocardial ischemia among patients without signs of coronary atherosclerosis with additional hemodynamic risk facts such as tahicardia, spasms of coronary artery, hypertrophie of myocard. Clinical symptomatology of the acute coronary syndrome is more

Hemifacial microsomia in cat-eye syndrome: 22q11.1-q11.21 as candidate loci for facial symmetry.

2013-08-01

Cat-Eye syndrome (CES), (OMIM 115470) also known as chromosome 22 partial tetrasomy or inverted duplicated 22q11, was first reported by Haab [1879] based on the primary features of eye coloboma and anal atresia. However, >60% of the patients lack these primary features. Here, we present a 9-month-old female who at birth was noted to have multiple defects, including facial asymmetry with asymmetric retrognathia, bilateral mandibular hypoplasia, branchial cleft sinus, right-sided muscular torticollis, esotropia, and an atretic right ear canal with low-to-moderate sensorineural hearing loss, bilateral preauricular ear tag/pits, and two skin tags on her left cheek. There were no signs of any colobomas or anal atresia. Hemifacial microsomia (HFM) was suspected clinically. Chromosome studies and FISH identified an extra marker originated from 22q11 consistent with CES, and this was confirmed by aCGH. This report expands the phenotypic variability of CES and includes partial tetrasomy of 22q11.1-q11.21 in the differential diagnosis of HFM. In addition, our case as well as the previous association of 22q11.2 deletions and duplications with facial asymmetry and features of HFM, supports the hypothesis that this chromosome region harbors genes important in the regulation of body plan symmetry, and in particular facial harmony.

Infantile spasms (IS) is a catastrophic childhood seizure disorder that is characterized by extensor and/or flexor spasms, cognitive deterioration and a characteristic EEG abnormality. The latter consists of a pattern of a spike-wave followed by an electrodecremental response (EDR), which is a flattening of the EEG waveform amplitude. The mechanism/circuitry that underpins IS is unknown. Children with Down Syndrome (DS) are particularly vulnerable to IS. The standard mouse model of DS is the Ts65Dn mutant mouse (Ts). Using the Ts mouse, we have created an animal model of IS in DS. This model entails the treatment of Ts mice with a GABA B R agonist with a resultant recapitulation of the semiological, electrographic, and pharmacological phenotype of IS. One of the genes triplicated in Ts mice is the kcnj6 gene which codes for the G-protein inwardly rectifying potassium channel 2 (GIRK2) protein. We have shown that over expression of GIRK2 in Ts brain is necessary for the production of the GABA B R agonist induced IS phenotype in the Ts mouse. Here, we ask the question whether the excess GIRK2 is sufficient for the production of the GABA B R agonist induced IS phenotype. To address this question, we used kcnj6 triploid mice, and compared the number of spasms via video analysis and EDR events via EEG to that of the WT mice. We now show that GABA R R agonist-treated kcnj6 triploid mice failed to show susceptibility to the IS phenotype. Therefore, over expression of GIRK2 in the brain is necessary, but not sufficient to confer susceptibility to the GABA B R agonist-induced IS phenotype in the Ts model of DS. It is therefore likely that GIRK2 is working in concert with another factor or factors that are altered in the Ts brain in the production of the GABA B R agonist-induced IS phenotype.

We used optical coherence tomography, a catheter-based intravascular imaging modality, to measure the degree of radial artery spasm induced by means of harvest with electrocautery or a harmonic scalpel in patients undergoing coronary artery bypass grafting. Methods Radial arteries were harvested from 44 consecutive patients with a harmonic scalpel (n = 15) or electrocautery (n = 29). Vessels were imaged before harvesting and after removal from the arm, with saphenous vein tracts serving as internal controls. Optical coherence tomographic findings for the degree of harvesting-induced injury were validated against histologic measures. Results Optical coherence tomographic measures of endovascular dimensions and injury correlated strongly with histologic findings. Mean luminal volume, a measure of vasospasm, decreased significantly less after harvesting with a harmonic scalpel (9% ± 7%) than with electrocautery (35% ± 6%, P = .015). Completely intact intima was present in 11 (73%) of 15 radial arteries harvested with a harmonic scalpel (73%) compared with 9 of 29 arteries harvested by means of electrocautery (31%, P = .011). Intraoperative flow measurements and patency rates at 5 days postoperatively were not significantly different among groups. Conclusions Optical coherence tomography provides a level of speed and accuracy for quantifying endothelial injury and vasospasm that has not been described for any other modality, suggesting potential as an intraoperative quality assurance tool. Our optical coherence tomographic findings suggest that the harmonic scalpel induces less spasm and intimal injury compared with electrocautery. PMID:19026820

The relapse of hemifacial microsomia was thought to be highly related to the soft tissue envelope around the mandible angle mainly composed by masseter and medial pterygoid. According to the reason, we tried to apply masseter injection of type A botulinum toxin to weaken the soft envelope tension on the early stage post mandible distraction in adult HFM patients. Eight patients diagnosed with HFM were studied and randomly assigned to an experimental or control group. Patients in the experimental group were treated with DO, orthognathic surgeries, autologous fat grafting, and bilateral masseter muscle injection with type A botulinum toxin. The patients in control group were treated with the same procedures as the patients in experimental group except for masseter muscle injection with type A botulinum toxin. The recurrence rates of both groups were evaluated and analyzed after nearly 1 year of follow-up. The mean recurrence rate was 26.30% ± 11.84% (range 7.62%-37.27%) in the 8 patients after 1-year follow-up. The relapse rate was 16.32% ± 7.78% (7.62%-26.22%) in the experimental group and 36.28% ± 1.03% (34.84%-37.27%) in the control group. There was a significant difference (P = 0.002) between the experimental group and the control group. The combination of DO, orthognathic surgeries, autologous fat particle transplantation, and masseter muscle type A botulinum toxin injection technique could be a comprehensive treatment plan for adult patients of HFM. Furthermore, masseter injection of type A botulinum toxin might be an alternative method to reduce the early recurrence rate of postoperative adult patients of HFM.

Patients with hemifacial microsomia may have a missing ear on the deficient side of the face. The fabrication of an ear for such individuals usually has been accomplished by directly measuring the ear on the normal side to construct a prosthesis based on these dimensions, and the positioning has been, to a large extent, primarily operator-dependent. The aim of the present study was to compare three methods, developed from the identification of landmarks plotted on three-dimensional surface scans, to evaluate the position of an artificial ear on the deficient side of the face compared with the position of the natural ear on the normally developed side. Laser scans were undertaken of the faces of 14 subjects with hemifacial microsomia. Landmarks on the ear and face on the normal side were identified. Three methods of mirroring the normal ear on the deficient side of the face were investigated, which used either facial landmarks from the orbital area or a zero reference point generated from the intersection of three orthogonal planes on a frame of reference. To assess the methods, landmarks were identified on the ear situated on the normal side as well as on the face. These landmarks yielded paired dimensional measurements that could be compared between the normal and deficient sides. Mean differences and 95% confidence intervals were calculated. It was possible to mirror the normal ear image on to the deficient side of the face using all three methods. Generally only small differences between the dimensional measurements on the normal and deficient sides were observed. However, two-way analysis of variance revealed statistically significant differences between the three methods (P = .005). The method of mirroring using the outer canthi was found to result in the smallest dimensional differences between the anthropometric points on the ear and face between the normally developed and deficient sides. However, the effects of the deformity can result in limitations in

Mutations in the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene have been identified in patients with Rett syndrome, West syndrome, and X-linked infantile spasms sharing the common features of generally intractable early seizures and mental retardation. Disease-causing mutations are distributed in both the catalytic domain and in the large COOH terminus. In this report, we examine the functional consequences of some Rett mutations of CDKL5 together with some synthetically designed derivatives useful to underline the functional domains of the protein. The mutated CDKL5 derivatives have been subjected to in vitro kinase assays and analyzed for phosphorylation of the TEY (Thr-Glu-Tyr) motif within the activation loop, their subcellular localization, and the capacity of CDKL5 to interact with itself. Whereas wild-type CDKL5 autophosphorylates and mediates the phosphorylation of the methyl-CpG-binding protein 2 (MeCP2) in vitro, Rett-mutated proteins show both impaired and increased catalytic activity suggesting that a tight regulation of CDKL5 is required for correct brain functions. Furthermore, we show that CDKL5 can self-associate and mediate the phosphorylation of its own TEY (Thr-Glu-Tyr) motif. Eventually, we show that the COOH terminus regulates CDKL5 properties; in particular, it negatively influences the catalytic activity and is required for its proper sub-nuclear localization. We propose a model in which CDKL5 phosphorylation is required for its entrance into the nucleus whereas a portion of the COOH-terminal domain is responsible for a stable residency in this cellular compartment probably through protein-protein interactions.

Patients with hemifacial microsomia (HFM) and Kaban-Pruzansky type III mandibular deformities require ramus construction with autologous tissue. The free fibula flap, an alternative to the costochondral graft, has favorable characteristics for this construction but may be associated with temporomandibular joint ankylosis. The purposes of this study were to present a series of patients with HFM who underwent free fibula flap ramus construction, to determine the incidence of ankylosis, and to identify perioperative factors associated with ankylosis. We performed a retrospective cohort study of patients with HFM who underwent ramus construction with a free fibula flap at Boston Children's Hospital from 2003 to 2015. Patients who had at least 1 year of follow-up and complete medical records were included. The predictor variables included demographic information, HFM severity, surgical history, and operative details. The primary outcome variable was the occurrence of ankylosis. Descriptive statistics were calculated, and significance was set at P < .05. We included 8 patients (75% of whom were female patients) in the study sample. Patients underwent construction at a mean age of 11.4 ± 5.9 years (range, 5 to 21 years). In 5 patients (63%), ankylosis developed during the follow-up period of 7.3 ± 4.8 years. The average time from construction to ankylosis was 4.2 ± 3.7 years. The only predictor variable statistically significantly associated with ankylosis was the use of a contralateral releasing osteotomy, which reduced the rate of ankylosis (P = .035). There was a trend toward a younger age in patients in whom ankylosis developed (8.8 ± 2.6 years) compared with those without ankylosis (15.5 ± 8.1 years, P = .392). The free fibula flap can be associated with a high rate of ankylosis when used for ramus construction in patients with HFM. Passive flap insertion and/or use of a contralateral releasing osteotomy may reduce this risk. Copyright �

Fetal spasms after the administration of electroconvulsive therapy in pregnancy: our experience.

Most psychotropic drugs are not approved for use during pregnancy. Electroconvulsive therapy (ECT) might be an effective and safe treatment option for several psychiatric disorders in pregnant women. This study assessed ECT for treating major psychoses during pregnancy, taking all possible adverse effects into account. We scrutinized all biomedical reviews on ECT during pregnancy published within the past 10 years, and present our experience with 3 patients in different phases of pregnancy that were treated with ECT between December 2009 and July 2012. Four to 5 ECT sessions were administered to pregnant women (10th to 28th week of pregnancy) with severe psychoses, and fetal heartbeat and movements were monitored during ECT and for 2 hours afterward. Bizarre fetal spasms occurred in pregnant women treated with ECT. The authors are not aware of any similar description in the published reviews on this topic, to date. Still, all 3 women had successful deliveries, and the infants remained healthy during follow-ups ranging from 1 to 3.5 years. These data fill a lacking gap in the literature regarding long-term infant outcomes after ECT administration to pregnant women. This supports the theory that ECT may be an excellent treatment solution for pregnant women with certain severe mental disorders. Electroconvulsive therapy may be an acceptable approach for preventing pharmacotherapy risks or danger arising from injuries associated with mental illnesses in pregnant women. Nonetheless, careful monitoring of both mother and baby is absolutely necessary when considering ECT during pregnancy.

The Afghanistan Surge saw NATO troops working with their Afghan partners to remove Taliban governance and replace it with a more democratic model. As part of this endeavor, medical support for both trauma and humanitarian cases was needed. Identify and discuss disease trends to better prepare for future combat medical treatments. Retrospective review of operative experience from a neurosurgeon from November 2010 to April 2011. 63 cases were performed on 20 NATO and 43 Afghan patients. Combat-related neurotrauma represented 73% (46/63) of cases and humanitarian cases represented the remainder. The most common diseases among humanitarian cases were benign tumors (29%, 5/17), cranioplasty (23%, 4/17), obstructive hydrocephalus (11%, 2/17), nonobstructive hydrocephalus (11%, 2/17), hemifacial spasm (11%, 2/17), and cerebral angiography (11%, 2/17). There was 1 death from ventriculitis for a complication rate of 6%. In select well-nourished, patients with minimal risk of needing tracheostomy, humanitarian neurosurgery can be safely performed in theater with a complication rate (6%) no worse than patients operated on in the United States.

Autoantibodies that bind to voltage-gated potassium-channel complex proteins (VGKC-complex antibodies) occur frequently in adults with limbic encephalitis presenting with cognitive impairment and seizures. Recently, VGKC-complex antibodies have been described in a few children with limbic encephalitis, and children with unexplained encephalitis presenting with status epilepticus. We report a case of infantile-onset epileptic spasms and developmental delay compatible with epileptic encephalopathy. Our patient was a female infant, aged 4 months at presentation. She had evidence of immune activation in the central nervous system with elevated cerebrospinal fluid neopterin and mirrored oligoclonal bands, which prompted testing for autoantibodies. VGKC-complex antibodies were elevated (201 pmol/L, normal<100), but extended antibody testing, including leucine-rich glioma-inactivated 1 (LGI1) and contactin-associated protein 2 (CASPR2), was negative. The patient showed a partial response to steroid treatment, which was started late in the disease course. On review at 13 months of age, her development was consistent with an age of 5 to 6 months. These results suggest that VGKC-complex antibodies might represent a marker of immune therapy responsiveness in a subgroup of patients with infantile epileptic encephalopathy. © The Authors.

[Bell's palsy].

Prud'hon, S; Kubis, N

Idiopathic peripheral facial palsy, also named Bell's palsy, is the most common cause of peripheral facial palsy in adults. Although it is considered as a benign condition, its social and psychological impact can be dramatic, especially in the case of incomplete recovery. The main pathophysiological hypothesis is the reactivation of HSV 1 virus in the geniculate ganglia, leading to nerve edema and its compression through the petrosal bone. Patients experience an acute (less than 24 hours) motor deficit involving ipsilateral muscles of the upper and lower face and reaching its peak within the first three days. Frequently, symptoms are preceded or accompanied by retro-auricular pain and/or ipsilateral face numbness. Diagnosis is usually clinical but one should look for negative signs to eliminate central facial palsy or peripheral facial palsy secondary to infectious, neoplastic or autoimmune diseases. About 75% of the patients will experience spontaneous full recovery, this rate can be improved with oral corticotherapy when introduced within the first 72 hours. To date, no benefit has been demonstrated by adding an antiviral treatment. Hemifacial spasms (involuntary muscles contractions of the hemiface) or syncinesia (involuntary muscles contractions elicited by voluntary ones, due to aberrant reinnervation) may complicate the disease's course. Electroneuromyography can be useful at different stages: it can first reveal the early conduction bloc, then estimate the axonal loss, then bring evidence of the reinnervation process and, lastly, help for the diagnosis of complications.

Vascular loops in the cerebellopontine angle (CPA) and their relationship to cranial nerves have been used to explain neurological symptoms. The anterior inferior cerebellar artery (AICA) has variable branches producing vascular loops that can compress the facial cranial nerve (CN) VII and vestibulocochlear (CN VIII) nerves. AICA compression of the facial-vestibulocochlear nerve complex can lead to various clinical presentations, including hemifacial spasm (HFS), tinnitus, and hemiataxia. The formation of arterial loops inside or outside of the internal auditory meatus (IAM) can cause abutment or compression of CN VII and CN VIII. Twenty-five (50 sides) fresh adult cadavers underwent dissection of the cerebellopontine angle in the supine position. In regard to relationships between the AICA and the nerves of the facial/vestibulocochlear complex, 33 arteries (66%) traveled in a plane between the facial/nervus intermedius nerves and the cochlear and vestibular nerves. Five arteries (10%) traveled below the CN VII/VIII complex, six (12%) traveled posterior to the nerve complex, four (8%) formed a semi-circle around the upper half of the nerve complex, and two (4%) traveled between and partially separated the nervus intermedius and facial nerve proper. Our study found that the majority of AICA will travel in a plane between the facial/nervus intermedius nerves and the cochlear and vestibular nerves. Although the relationship between the AICA and porus acusticus and AICA and the nerves of the CN VII/VIII complex are variable, based on our findings, some themes exist. Surgeons should consider these with approaches to the cerebellopontine angle. PMID:29057182

Parry-Romberg disease is a rare condition that results in progressive hemifacial atrophy, involving the skin, dermis, subcutaneous fat, muscle, and, finally, cartilage and bone. Patients have been treated with dermofat or fat grafts or by microvascular free flap transfer. We hypothesized that adipose-derived stem cells (ASCs) may improve the results of microfat grafting through enhancing angiogenesis. We evaluated the utility of ASC in microfat grafting of patients with Parry-Romberg disease by measuring the change in the hemifacial volumes after injection of ASCs with microfat grafts or microfat grafts alone. In April 2008, this investigation was approved by the Korean Food and Drug Administration and the institutional review board of the Asan Medical Center (Seoul, Korea) that monitor investigator-initiated trials. Between May 2008 and January 2009, 10 volunteers with Parry-Romberg disease (5 men and 5 women; mean age, 28 y) were recruited; 5 received ASC and microfat grafts and 5 received microfat grafts only. The mean follow-up period was 15 months. Adipose-derived stem cells were obtained from abdominal fat by liposuction and were cultured for 2 weeks. On day 14, patients were injected with fat grafts alone or plus (in the test group) 1 × 10 ASCs. Patients were evaluated postoperatively using a 3-dimensional camera and 3-dimensional CT scans, and grafted fat volumes were objectively calculated. Successful outcomes were evident in all 5 patients receiving microfat grafts and ASCs, and the survival of grafted fat was better than in patients receiving microfat grafts alone. Before surgery, the mean difference between ipsilateral and contralateral hemiface volume in patients receiving microfat grafts and ASCs was 21.71 mL decreasing to 4.47 mL after surgery. Overall resorption in this ASC group was 20.59%. The mean preoperative difference in hemiface volume in those receiving microfat grafts alone was 8.32 mL decreasing to 3.89 mL after surgery. Overall

Is Tadpole Pupil in an Adolescent Girl Caused by Denervation Hypersensitivity?

PubMed

Hansen, Jonas Kjeldbjerg; Møller, Hans Ulrik

2017-06-01

Tadpole pupil is a rarely encountered phenomenon caused by episodic, segmental iris dilator muscle spasm of short duration (2-15 minutes), occurring in clusters without a known precipitating factor. It has most commonly been described in women aged 28 to 48 years. A few hypotheses on pathogenesis have been discussed but none has been proved. Here, we present an adolescent girl with bilateral tadpole pupil that appeared during physical exercise. This is the first pediatric case of tadpole pupil, not caused by preceding surgery, to be published. Based on (1) this case in which tadpole pupil developed when the norepinephrine level rose during exercise, (2) the high ratio of patients with tadpole pupil who concurrently have or later develop Horner syndrome, in which denervation hypersensitivity is well described, (3) a previous report of a patient with both tadpole pupil and Horner syndrome who had denervation hypersensitivity on pharmacological testing, (4) a 29-year-old man with unilateral tadpole pupil induced by exercise, and (5) a 19-year-old man with bilateral tadpole pupil and possible autonomic neuropathy, we suggest denervation hypersensitivity as a probable pathogenic mechanism causing tadpole pupil. In addition, a suggestion for investigations to be performed in future pediatric cases is provided. Georg Thieme Verlag KG Stuttgart · New York.

Septoplasty is a commonly used procedure for correcting septal cartilage deformities. Hemorrhage, abscesses, scaling, adhesions, and scar tissue are often seen after the operation of the septoplasty, but temporary or permanent visual loss due to local anesthetic use has been reported very rarely in the literature. The authors also aimed to present a female patient with retinal artery spasm in the right eye after septoplasty in this article. A 27-year-old female patient was admitted to the authors' clinic with long-standing nasal obstruction and postnasal drip. There was no feature in her history and also no sign other than nasal septal deviation on physical examination. The patient was informed about the operation and the operation was planned. Emergency eye consultation was requested after the patient said that the right eye of the patient had never seen in the postoperative wake-up hall. Examination by an ophthalmologist; mild exotropia and total loss of vision in the right eye (including loss of light reflex) was detected. The light reaction in the affected eye was negative and indirect reaction was positive. After enlargement of the pupil, fundus examination revealed that the right posterior pole region (inside of the macula and vessel arches) was pale and no central retinal artery pulsation was observed. The patient was diagnosed with central retinal artery occlusion and emergency intervention was performed. The right eye massage, paracentesis, and hyperbaric oxygen therapy returned to the patient's visual function.

The expanded forehead flap, using temporal pedicles, has been employed extensively in facial reconstruction. To overcome the disadvantages of the traditional dual temporal pedicles, such as the limited transfer range and the short length of the flap, the distal supercharging technique can be applied to lengthen the flap and extend the transfer range, especially in the cases with a past temporal burn injury. This article aims to present an application of the distal supercharged expanded forehead flap procedure for hemi-facial reconstruction and discuss the haemodynamics of the expanded forehead flap. The tissue expander implantation and the following forehead tissue expansion were performed regularly. When the forehead skin expansion was completed, an expanded forehead flap was created and transferred to the damaged facial area with one distal temporal vessel pedicle that was anastomosed with facial vessels in a supercharged way. All patients were analysed retrospectively. From September 2009 to September 2011, eight male patients and one female patient were treated using this method. Their flaps size ranged from 20 cm × 8 cm to 30 cm × 11 cm and no flap loss occurred. Patients came in for follow-ups 9-16 months after the procedures. All the patients were satisfied with the results. The supercharging expanded forehead flap procedure can provide reliable flap vascularity due to its elastic transferring abilities. By using a distal supercharging technique, we can lengthen and widen the flap to tailor it to the defect, while also minimising the donor defect in the patients with a past temporal injury.

Intraoperative monitoring of brain stem auditory evoked potential during microvascular decompression (MVD) prevent hearing loss (HL). Previous studies have shown that changes in wave III (wIII) are an early and sensitive sign of auditory nerve injury. To evaluate the changes of amplitude and latency of wIII of brain stem auditory evoked potential during MVD and its association with postoperative HL. Hearing loss was classified by American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) criteria, based on changes in pure tone audiometry and speech discrimination score. Retrospective analysis of wIII in patients who underwent intraoperative monitoring with brain stem auditory evoked potential during MVD was performed. A univariate logistic regression analysis was performed on independent variables amplitude of wIII and latency of wIII at change max and On-Skin, or a final recording at the time of skin closure. A further analysis for the same variables was performed adjusting for the loss of wave. The latency of wIII was not found to be significantly different between groups I and II. The amplitude of wIII was significantly decreased in the group with HL. Regression analysis did not find any increased odds of HL with changes in the amplitude of wIII. Changes in wave III did not increase the odds of HL in patients who underwent brain stem auditory evoked potential s during MVD. This information might be valuable to evaluate the value of wIII as an alarm criterion during MVD to prevent HL.

The aims of this systematic review and meta-analysis were to assess (i) estimates of good neurodevelopmental outcome in infantile spasms (IS), (ii) if neurodevelopmental outcome has changed since the publication of the first guideline on medical treatment of IS in 2004 and (iii) effect of lead time to treatment (LTTT). The Medline, Embase, Cochrane, PsycINFO, Web of Science and Scopus databases, and reference lists of retrieved articles were searched. Studies inclusion criteria were: (i) >5 patients with IS, (ii) mean/median follow-up of >6 months, (iii) neurodevelopmental outcome, and (iv) randomized and observational studies. The data extracted included proportion of good neurodevelopmental outcome, year of publication, cryptogenic or symptomatic IS and LTTT. Of the 1436 citations screened, 55 articles were included in final analysis, with a total of 2967 patients. The pooled estimate for good neurodevelopmental outcome was 0.236 (95% CI: 0.193-0.286). There was no difference between the proportions of good neurodevelopmental outcome for the 21 studies published after 2004 [0.264 (95% CI: 0.197-0.344)] compared to the 34 studies published before 2004 [0.220 (95% CI: 0.168-0.283)] (Q value=0.862, p=0.353). The pooled estimate of good neurodevelopmental outcome for cryptogenic IS [0.543 (95% CI: 0.458-0.625)] was higher than symptomatic IS [0.125 (95% CI: 0.09-0.171)] (Q value=69.724, p<0.001). Risk ratio of LTTT <4weeks relative to >4weeks for good neurodevelopmental outcome of 8 studies was 1.519 (95% CI: 1.064-2.169). Neurodevelopmental outcome was overall poor in patients with IS and has not changed since the publication of first guideline on IS. Although cryptogenic IS has better prognosis than symptomatic IS, the outcome for cryptogenic IS remained poor. There was heterogeneity in neurodevelopmental outcome ascertainment methods, highlighting the need for a more standardized and comprehensive assessment of cognitive, behavioural, emotional and functional

Closed-Suction Drainage and Cerebrospinal Fluid Leakage Following Microvascular Decompression : A Retrospective Comparison Study

Objective We performed this study to investigate whether the use of closed-suction drainage following microvascular decompression (MVD) causes cerebrospinal fluid (CSF) leakage. Methods Between 2004 and 2011, a total of 157 patients with neurovascular compression were treated with MVD. MVD was performed for hemifacial spasm in 150 (95.5%) cases and for trigeminal neuralgia in 7 (4.5%) cases. The mean age of the patients was 49.8±9.6 years (range, 20-69). Dural substitutes were used in 44 (28.0%) patients. Ninety-two patients (58.6%) were underwent a 4-5 cm craniotomy using drainage (drainage group), and 65 (41.4%) did a small 2-2.5 cm retromastoid craniectomy without closed-suction drainage (no-drainage group). Results Eleven (7.0%) patients experienced CSF leakage following MVD based on the criteria of this study; all of these patients were in the drainage group. In the unadjusted analyses, the incidence of CSF leakage was significantly related with the use of closed-suction drainage following MVD (12.0% in the drainage group vs. 0% in the no-drainage group, respectively; p=0.003; Fisher's exact test). Those who received dural substitutes and the elderly (cut-off value=60 years) exhibited a tendency to develop CSF leakage (p=0.075 and p=0.090, respectively; Fisher's exact test). In the multivariate analysis, only the use of closed-suction drainage was significantly and independently associated with the development of CSF leakage following MVD (odds ratio=9.900; 95% confidence interval, 1.418 to infinity; p=0.017). Conclusion The use of closed-suction drainage following MVD appears to be related to the development of CSF leakage. PMID:24175025

[Botulinum toxin: from poison to drug. A historical review].

Botulinumtoxin (BTX) is a neurotoxin produced from Clostridium botulinum under anaerobic conditions and is responsible for botulism, a notifiable, bacterial form of food poisoning. The first case of botulism is believed to have occurred in 1735. An epidemic in Southern Germany in 1793 claimed the death of over the half of those patients who had become ill through eating uncooked blood sausages. The term "pharmakon" is Greek and implicates that a drug originates from poison (potion, remedy). Theophrastus Bombast von Hohenheim known as Paracelsus (1493/94-1541) first described this duality with his dictum "alle ding sind gift und nichts on gift; alein die dosis macht das ein ding kein gift ist" (only the dose makes a remedy poisonous). In Baden-Württemberg in 1817, the poet and physician Dr. Justinus Christian Kerner described the symptoms of botulism, so that at this time botulism was also called Kerner disease. Until the turn of the century the reason for poisoning was not known. Van Ermengem succeeded in isolating the anaerobic bacterium causing botulism, but the specific mechanism of BTX was only established after the second World War. In the late seventies the ophthalmologist Dr. Alan Scott used BTX the first time in the treatment of strabismus. The drug was then used in the treatment of several muscle spasticities such as, for example, torticollis or hemifacial spasm. Only recently BTX has been successfully used for focal hyperhidrosis. We review the history of botulinum toxin from its discovery in the nineteenth century and the research into its effect in the middle of the 20th century up to its clinical use at the present time.

Revuelta-Gutiérrez, Rogelio; Velasco-Torres, Héctor Sebastián; Vales Hidalgo, Lourdes Olivia; Martínez-Anda, Jaime Jesús

The coexistence of hemifacial spasm and trigeminal neuralgia, a clinical entity known as painful tic convulsive, was first described in 1910. It is an uncommon condition that is worthy of interest in neurosurgical practice, because of its common pathophysiology mechanism: Neuro-vascular compression in most of the cases. To present 2 cases of painful tic convulsive that received treatment at our institution, and to give a brief review of the existing literature related to this. The benefits of micro-surgical decompression and the most common medical therapy used (botulin toxin) are also presented. Two cases of typical painful tic convulsive are described, showing representative slices of magnetic resonance imaging corresponding to the aetiology of each case, as well as a description of the surgical technique employed in our institution. The immediate relief of symptomatology, and the clinical condition at one-year follow-up in each case is described. A brief review of the literature on this condition is presented. This very rare neurological entity represents less than 1% of rhizopathies and in a large proportion of cases it is caused by vascular compression, attributed to an aberrant dolichoectatic course of the vertebro-basilar complex. The standard modality of treatment is micro-vascular surgical decompression, which has shown greater effectiveness and control of symptoms in the long-term. However medical treatment, which includes percutaneous infiltration of botulinum toxin, has produced similar results at medium-term in the control of each individual clinical manifestation, but it must be considered as an alternative in the choice of treatment.

While the facial rejuvenating effect of botulinum toxin type A is well known and widespread, its use in body and facial contouring is less common. We first describe its use for deliberate muscle volume reduction, and then document instances of unanticipated and undesirable muscle atrophy. Finally, we investigate the potential long-term adverse effects of botulinum toxin-induced muscle atrophy. Although the use of botulinum toxin type A in the cosmetic patient has been extensively studied, there are several questions yet to be addressed. Does prolonged botulinum toxin treatment increase its duration of action? What is the mechanism of muscle atrophy and what is the cause of its reversibility once treatment has stopped? We proceed to examine how prolonged chemodenervation with botulinum toxin can increase its duration of effect and potentially contribute to muscle atrophy. Instances of inadvertent botulinum toxin-induced atrophy are also described. These include the "hourglass deformity" secondary to botulinum toxin type A treatment for migraine headaches, and a patient with atrophy of multiple facial muscles from injections for hemifacial spasm. Numerous reports demonstrate that muscle atrophy after botulinum toxin type A treatment occurs and is both reversible and temporary, with current literature supporting the notion that repeated chemodenervation with botulinum toxin likely responsible for both therapeutic and incidental temporary muscle atrophy. Furthermore, duration of response may be increased with subsequent treatments, thus minimizing frequency of reinjection. Practitioners should be aware of the temporary and reversible effect of botulinum toxin-induced muscle atrophy and be prepared to reassure patients on this matter. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Objetivo: El propósito del presente trabajo es presentar los resultados de 13 pacientes con diagnóstico de espasmo hemifacial (EHF), en los cuales se realizó una descompresión microvascular (DMV). Material y Método: Desde Junio de 2005 a Mayo de 2014, 13 pacientes con diagnóstico de EHF fueron intervenidos quirúrgicamente, realizando una DMV. Se evaluó: edad, sexo, tiempo de evolución de la sintomatología, hallazgos intraoperatorios y resultados postoperatorios. Resultados: De los 13 pacientes intervenidos, 7 fueron mujeres y 6 varones. La media de edad fue de 53 años. El tiempo medio entre el inicio de la sintomatología y la intervención quirúrgica osciló entre 3 y 9 años. En todos los casos el EHF era típico, uno de ellos con neuralgia trigeminal concomitante, observándose en todos compresión neurovascular intraoperatoria. Por orden decreciente de frecuencia la causa de la compresión fue arteria cerebelosa anteroinferior, arteria cerebelosa posteroinferior, arteria dolicomega basilar y arteria dolicomega vertebral. El seguimiento postoperatorio fue en promedio de 24 meses. El 62% presentó desaparición postquirúrgica inmediata de la sintomatología preoperatoria, el 30% desaparición tras un período de 3 semanas a 2 meses (8% con mejoría parcial), y en el 8% no hubo mejoría. En cuanto a las complicaciones postoperatorias: 3 pacientes presentaron paresia facial II-III en la escala de House-Brackman (se recuperaron en un período de 6 meses), y 1 paciente presentó fístula de líquido cefalorraquídeo. Ninguno de los pacientes de la serie presentaron hipoacusia transitorio o permanente. Conclusión: La DMV como tratamiento del EHF es un procedimiento efectivo y seguro, que permite la resolución completa de la patología en la mayoría de los casos. PMID:27127708

A 56-year-old man presented with typical angina pectoris lasting >20 min associated with precordial ST-segment elevation. Urgent coronary angiography showed critical stenosis in the proximal segment of the left anterior descending artery, which resolved with intracoronary nitrate application. He was subsequently diagnosed with hyperthyroidism secondary to exposure of iodinated contrast agent which is thought to be the cause of the coronary spasm. Symptoms resolved upon treatment with propylthiouracil, slow-release diltiazem, isosorbide mononitrate, and aspirin. This unusual case highlights the importance of considering hyperthyroidism in the differential diagnosis of chest pain and coronary artery spasm. We suggest routine thyroid function testing in patients with coronary spasm.

Norrie disease (ND) is a rare X-linked recessive disorder characterized by congenital blindness and in some cases, mental retardation and deafness. Other neurological complications, particularly epilepsy, are rare. We report on a novel mutation identified in a patient with ND and profound mental retardation. The patient was diagnosed at the age of 6 months due to congenital blindness. At the age of 8 months he developed infantile spasms, which were diagnosed at 11 months as his EEG demonstrated hypsarrhythmia. Mutation analysis of the ND gene (NDP) of the affected child and his mother revealed a novel missense mutation at position c.134T > A resulting in amino acid change at codon V45E. To the best of our knowledge, such severe neurological involvement has not been previously reported in ND patients. The severity of the phenotype may suggest the functional importance of this site of the NDP gene.

Postrenal acute kidney injury in a patient with unilateral ureteral obstruction caused by urolithiasis: A case report.

PubMed

In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal function, as it humorally influences the renal hemodynamics. A 66-year-old man with a past medical history of hypertension and diabetes mellitus came to our outpatient clinic because of right abdominal dullness. Unilateral ureteral obstruction caused by a radio-opaque calculus in the right upper ureter and a secondary renal dysfunction. As oral hydration and the use of calcium antagonists failed to allow the spontaneous stone passage, extracorporeal shock wave lithotripsy (ESWL) was performed. Immediately after the passage of the stone, the number of red blood cells in the urine was dramatically decreased and the serum creatinine level almost returned to the normal range with the significant increase in glomerular filtration rate. Unilateral ureteral obstruction by the calculus, which caused reflex vascular constriction and ureteral spasm in the contralateral kidney, was thought to be responsible for the deteriorating renal function.

Coronary artery spasm (CAS) is associated with ventricular arrhythmias (VA). Much controversy remains regarding the best therapeutic interventions for this specific patient subset. We aimed to evaluate the clinical outcomes of patients with a history of life-threatening VA due to CAS with various medical interventions, as well as the need for ICD placement in the setting of optimal medical therapy. A multicentre European retrospective survey of patients with VA in the setting of CAS was aggregated and relevant clinical and demographic data was analysed. Forty-nine appropriate patients were identified: 43 (87.8%) presented with VF and 6 (12.2%) with rapid VT. ICD implantation was performed in 44 (89.8%). During follow-up [59 (17-117) months], appropriate ICD shocks were documented in 12. In 8/12 (66.6%) no more ICD therapies were recorded after optimizing calcium channel blocker (CCB) therapy. SCD occurred in one patient without ICD. Treatment with beta-blockers was predictive of appropriate device discharge. Conversely, non-dihydropyridine CCB therapy was significantly protective against VAs. Patients with life-threatening VAs secondary to CAS are at particularly high-risk for recurrence, especially when insufficient medical therapy is administered. Non-dihydropyridine CCBs are capable of suppressing episodes, whereas beta-blocker treatment is predictive of VAs. Ultimately, in spite of medical intervention, some patients exhibited arrhythmogenic events in the long-term, suggesting that ICD implantation may still be indicated for all.

Rett syndrome (RTT) is a severe neurodevelopmental disorder caused, in most classic cases, by mutations in the X-linked methyl-CpG-binding protein 2 gene (MECP2). A large degree of phenotypic variation has been observed in patients with RTT, both those with and without MECP2 mutations. We describe a family consisting of a proband with a phenotype that showed considerable overlap with that of RTT, her identical twin sister with autistic disorder and mild-to-moderate intellectual disability, and a brother with profound intellectual disability and seizures. No pathogenic MECP2 mutations were found in this family, and the Xq28 region that contains the MECP2 gene was not shared by the affected siblings. Three other candidate regions were identified by microsatellite mapping, including 10.3 Mb at Xp22.31-pter between Xpter and DXS1135, 19.7 Mb at Xp22.12-p22.11 between DXS1135 and DXS1214, and 16.4 Mb at Xq21.33 between DXS1196 and DXS1191. The ARX and CDKL5 genes, both of which are located within the Xp22 region, were sequenced in the affected family members, and a deletion of nucleotide 183 of the coding sequence (c.183delT) was identified in CDKL5 in the affected family members. In a screen of 44 RTT cases, a single splice-site mutation, IVS13-1G→A, was identified in a girl with a severe phenotype overlapping RTT. In the mouse brain, Cdkl5 expression overlaps—but is not identical to—that of Mecp2, and its expression is unaffected by the loss of Mecp2. These findings confirm CDKL5 as another locus associated with epilepsy and X-linked mental retardation. These results also suggest that mutations in CDKL5 can lead to a clinical phenotype that overlaps RTT. However, it remains to be determined whether CDKL5 mutations are more prevalent in specific clinical subgroups of RTT or in other clinical presentations. PMID:15492925

The aim of this study is to identify common causes, associated ophthalmological abnormalities, and systemic comorbidities in children in Andhra Pradesh, India, with cerebral visual impairment (CVI). A retrospective review of case records of all children aged <16 years with diagnosis of CVI seen between January 2016 and December 2016 was carried out. Data were collected for their age, gender, cause of CVI, refraction, accommodation, anterior and posterior segment examination findings, and systemic problems. A total of 124 patients were identified and studied (80 boys and 44 girls, mean age 5.23 years, 44.8% aged <2 years). The most common causes of CVI were hypoxic-ischemic encephalopathy (HIE) (34.4%), undetermined etiology (32.8%), neonatal seizures, and infantile spasms (16% each). The most common presenting complaints were poor vision (76%) and squint (11.2%). Profound visual impairment was seen in 88.8%, and 11.2% had high functioning CVI. Fifty-eight (46.4%) patients had significant refractive errors, 40 (32.25%) had strabismus, 4 (3.2%) had visually significant cataract, and 40 (32%) had optic atrophy. Motor delay was observed in 39.5%, speech delay was evident in 22.4%, and cognitive delay in 16%. HIE is the most common cause (one-third) of CVI in our population, and the majority of them presented at age <2 years (44.8%) with profound visual impairment (88.8%). A significant number of them have treatable ophthalmic conditions such as refractive errors (46.4%), accommodative insufficiency (12.1%), and cataract (3.2%), and more than one-third of them also have delay in other areas of development.

Accommodative spasm usually encompasses a classical triad of pseudomyopia, esodeviation and pupillary constriction. Accommodative spasm is most often psychogenic in nature; however, it may be associated with other organic diseases of which a rare cause is that of intracranial catheter complications. We report a case of dorsal midbrain syndrome with pseudomyopia in a patient with a blocked ventriculo-peritoneal shunt inserted for aqueductal stenosis. Clinical presentation was unusual in this patient as pseudomyopia occurred with exodeviation and without pupillary constriction.

The primary aim of this paper is to study the pre-operative characteristics, intra-operative changes and post-operative hearing outcomes in patients after complete loss of wave V of the brainstem auditory evoked potential. We retrospectively analyzed the brainstem auditory evoked potential data of 94 patients who underwent microvascular decompression for hemifacial spasm at our institute. Patients were divided into two groups - those with and those without loss of wave V. The differences between the two groups and outcomes were assessed using t-test and chi-squared tests. In our study 23 (24%) patients out of 94 had a complete loss of wave V, with 11 (48%) patients experiencing transient loss and 12 (52%) patients experiencing permanent loss. The incidence of hearing loss in patients with no loss of wave V was 5.7% and 26% in patients who did experience wave V loss. The incidence of hearing change in patients with no loss of wave V was 12.6% and 30.43% in patients who did experience wave V loss. Loss of wave V during the procedure or at the end of procedure significantly increases the odds of hearing loss. Hearing change is a significant under-reported clinical condition after microvascular decompression in patients who have loss of wave V. Copyright © 2014 Elsevier Ltd. All rights reserved.

Infantile spasms (IS; West syndrome) is a severe form of encephalopathy that typically affects infants younger than 2 years old. Pediatricians, pediatric neurologists, and other pediatric health care providers are all potentially key early contacts for families who have an infant with IS. The objective of this article is to assist pediatric health care providers in the detection of the disease and in the counseling and guidance of families who have an infant with IS. Treatment guidelines, consensus reports, and original research studies are reviewed to provide an update regarding the diagnosis and treatment of infants with IS. Web sites were searched for educational and supportive resource content relevant to providers and families of patients with IS. Early detection of IS and pediatrician referral to a pediatric neurologist for further evaluation and initiation of treatment may improve prognosis. Family education and the establishment of a multidisciplinary continuum of care are important components of care for the majority of patients with IS. The focus of the continuum of care varies across diagnosis, initiation of treatment, and short- and long-term needs. Several on-line educational and supportive resources for families and caregivers of patients with IS were identified. Given the possibility of poor developmental outcomes in IS, including the emergence of other seizure disorders and cognitive and developmental problems, early recognition, referral, and treatment of IS are important for optimal patient outcomes. Dissemination of and access to educational and supportive resources for families and caregivers across the lifespan of the child with IS is an urgent need. Pediatric health care providers are well positioned to address these needs.

Background: There is a lack of unified information on diagnosis and treatment of cerebral vasospasm (CV) after subarachnoid hemorrhage (SAH) among the hospitals in Japan. Thus, the aim of the study was to define the current practice in this area based on a survey by Japanese neurosurgeons. Methods: A survey on diagnosis and treatment of CV was sent to 414 hospitals each of which performs >100 neurosurgeries annually. Results: Responses were received from 240 hospitals (58.0%). Because accurate criteria for diagnosis of symptomatic vasospasm (SVS) were used in only 33.8% of the hospitals, we proposed a clinical definition of SVS that was approved at the 25th Spasm Symposium (Consensus 2009). This definition is simplified as follows: (1) the presence of neurological worsening; (2) no other identifiable cause of neurological worsening; and (3) confirmation of vasospasm by medical examinations. The results also showed that the Fisher CT scale is used differently for patients with ICH or IVH, with 41.3% of cases with ICH/IVH based on SAH that met Fisher criteria classified into Fisher group 1, 2 or 3, and 46.3% classified into Fisher group 4. There were no major differences in prophylactic therapies of CV and therapy for cerebral ischemia among the hospitals. Endovascular treatment for vasospasm was performed in most hospitals (78.7%); however, the criteria differed among the hospitals: (1) angiographic vasospasm and SVS appeared (37.9%), (2) only when aggressive therapy was ineffective (41.4%). Conclusion: We established a clinical definition of SVS based on the results of this survey (Consensus 2009). PMID:21748027

Nuclear import receptors of the KPNA family recognize the nuclear localization signal in proteins and together with importin-β mediate translocation into the nucleus. Accordingly, KPNA family members have a highly conserved architecture with domains that contact the nuclear localization signal and bind to importin-β. Here, we describe autosomal recessive mutations in KPNA7 found by whole exome sequencing in a sibling pair with severe developmental disability, infantile spasms, subsequent intractable epilepsy consistent with Lennox-Gastaut syndrome, partial agenesis of the corpus callosum, and cerebellar vermis hypoplasia. The mutations mapped to exon 7 in KPNA7 result in two amino-acid substitutions, Pro339Ala and Glu344Gln. On the basis of the crystal structure of the paralog KPNA2 bound to a bipartite nuclear localization signal from the retinoblastoma protein, the amino-acid substitutions in the affected subjects were predicted to occur within the seventh armadillo repeat that forms one of the two nuclear localization signal-binding sites in KPNA family members. Glu344 is conserved in all seven KPNA proteins, and we found that the Glu354Gln mutation in KPNA2 is sufficient to reduce binding to the retinoblastoma nuclear localization signal to approximately one-half that of wild-type protein. Our data show that compound heterozygous mutations in KPNA7 are associated with a human neurodevelopmental disease, and provide the first example of a human disease associated with mutation of a nuclear transport receptor.

Gitelman's syndrome is an autosomal recessive renal tubular disorder characterized by severe hypomagnesaemia, hypokalaemia, metabolic alkalosis and hypocalcaemia. It is caused by defective NaCl transport in the Distal Convoluted Tubule and presents in adolescence or adulthood, with a distinctly more benign course than Bartter's Syndrome. The dominant clinical features are muscle weakness, fatigue, carpopedal spasm, cramps and tetany. We report the case of a 26 year old male who presented with flaccid quadriparesis and carpopedal spasms, hypokalaemia, hypomagnesaemia, hypocalcaemia and severe urinary magnesium wasting. He was treated with potassium and magnesium supplementation and regained full function of all limbs.

High-resolution MR imaging is useful for diagnosis and preoperative planning in patients with NVC. Because high-field MR imaging promises higher SNR and resolution, the aim of this study was to determine the value of high-resolution 3D-CISS and 3D-TOF MRA at 3T compared with 1.5T in patients with NVC. Forty-seven patients with NVC, trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia were examined at 1.5T and 3T, including high-resolution 3D-CISS and 3D-TOF MRA sequences. Delineation of anatomic structures, overall image quality, severity of artifacts, visibility of NVC, and assessment of the SNR and CNR were compared between field strengths. SNR and CNR were significantly higher at 3T (P < .001). Significantly better anatomic conspicuity, including delineation of CNs, nerve branches, and assessment of small vessels, was obtained at 3T (P < .02). Severity of artifacts was significantly lower at 3T (P < .001). Consequently, overall image quality was significantly higher at 3T. NVC was significantly better delineated at 3T (P < .001). Six patients in whom NVC was not with certainty identifiable at 1.5T were correctly diagnosed at 3T. Patients with NVC may benefit from the higher resolution and greater sensitivity of 3T for preoperative assessment of NVC, and 3T may be of particular value when 1.5T is equivocal.

CDKL5 mutations cause severe epilepsy in infancy with subsequent epileptic encephalopathy. As yet, few studies report on long-term observations in patients with CDKL5-related epileptic encephalopathy. In this study, we describe the evolution of the epilepsy phenotype and the electroencephalographic (EEG) features in 4 patients during a maximum observation period of 22 years. All 4 patients had epilepsy starting with focal seizures in the first 3 months of life, evolving to epileptic spasms between the ages of 2 and 6 years and later on to tonic seizures. In 3 patients, epilepsy was resistant to antiepileptic therapy. Although there was no common EEG pattern in all patients, late hypsarrhythmia until the age of 9 years was observed in 2 patients. CDKL5-related epileptic encephalopathies are a group of refractory seizure disorders starting in early infancy. The phenomenon of late hypsarrhythmia may help define a subgroup of patients with severe and adverse outcomes.

OBJECTIVE To develop a spasticity scale for dogs with chronic deficits following severe spinal cord injury (SCI) for use in clinical assessment and outcome measurement in clinical trials. ANIMALS 20 chronically paralyzed dogs with a persistent lack of hind limb pain perception caused by an acute SCI at least 3 months previously. PROCEDURES Spasticity was assessed in both hind limbs via tests of muscle tone, clonus, and flexor and extensor spasms adapted from human scales. Measurement of patellar clonus duration and flexor spasm duration and degree was feasible. These components were used to create a canine spasticity scale (CSS; overall score range, 0 to 18). Temporal variation for individual dogs and interrater reliability were evaluated. Gait was quantified with published gait scales, and CSS scores were compared with gait scores and clinical variables. Owners were questioned regarding spasticity observed at home. RESULTS 20 dogs were enrolled: 18 with no apparent hind limb pain perception and 2 with blunted responses; 5 were ambulatory. Testing was well tolerated, and scores were repeatable between raters. Median overall CSS score was 7 (range, 3 to 11), and flexor spasms were the most prominent finding. Overall CSS score was not associated with age, SCI duration, lesion location, or owner-reported spasticity. Overall CSS score and flexor spasm duration were associated with gait scores. CONCLUSIONS AND CLINICAL RELEVANCE The CSS could be used to quantify hind limb spasticity in dogs with chronic thoracolumbar SCI and might be a useful outcome measure. Flexor spasms may represent an integral part of stepping in dogs with severe SCI.

Mutations within the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene are important causes of early-onset epileptic encephalopathies. We sought to determine the historic, clinical, and prognostic features of epilepsy secondary to CDKL5 mutations. We performed retrospective chart reviews of children at our institution with epilepsy and CDKL5 mutations. Six children were identified. One manifested a deletion in exons 10-15 of the CDKL5 gene, another manifested a single base-pair duplication in exon 3, and the rest manifested base-pair exchanges. The mean age of seizure onset was 1.8 months (range, 1-3 months). Although the majority (4/6, 67%) presented with partial-onset seizures, all children developed infantile spasms. All children demonstrated developmental delay and visual impairment. Although such mutations are X-linked, two children were boys. They did not present with more severe phenotypes than their female counterparts. Despite trials of antiepileptic drugs (mean, 5; range, 3-7), steroids/adrenocorticotropic hormone (4/6; 67%), and the ketogenic diet (6/6; 100%), all children manifested refractory seizures at last follow-up. Although no treatment eliminated seizures, topiramate, vigabatrin, and the ketogenic diet were most helpful at reducing seizure frequency. Copyright © 2012 Elsevier Inc. All rights reserved.

Epilepsy in two first years of life needs constant attention due to diagnostic and therapeutic difficulties. The aim of the study was to identify cause of symptomatic epilepsy in two first years of life children from miopolskie and podkarpackie provinces hospitalized in Pediatric Neurology Clinic of Children and Adolescents Neurology Cathedra UJ in Cracow. 102 children with epilepsy aged from 1 week to 24 months hospitalized between 1st of January 2006 and 31st of December 2007. The group included 47 girls and 55 boys. On the basis of clinical characteristics and results of additional examinations idiopathic epilepsy was diagnosed in 16/102 (13.3%) children and in remaining 86 (87.7%) symtopmatic epilepsy was established. Perinatal burdening was cause of epilepsy in 31/86 (33.72%) children. Other causes were identified in 32/54 children (59.3%) and in remaining 231 54 (40.7%) children the cause was not established. In 3/32 epilepsy occured in the course of hydrocephalus and in 3/32 children as one of CNS inflammation complications. Epilepsy as a result of vascular lesions and bleeding to CNS occured in 4 children. Multiple developmental deffects syndrome was diagnosed in 4 children and in 11 specific neurodevelopmental disorders were the cause of epilepsy. In 6 children epilepsy occured in the course of neurometabolic diseases, neurocutaneous syndromes and neoplasms. In children in two first years of life polimorphic seizures were diagnosed the most often (32/86 that is 37.2%) and tonic, tonic-clonic seizures were less often (21/86 that is 24.43%). Focal seizures occured in 20/86 (23.26%) patients, in 4/86 (4.65%) mioclonic jerks were observed and infantile spasms in 9/86 (10.46%). (1) In most hospitalized children in two first years of life symptomatic epilepsy was diagnosed. (2) Epilepsy in two first years of life was more often in boys. (3) The most often cause of symptomatic epilepsy was pathology of perinatal period. (4) Polymorphic seizures were the most

Pregnancy-related acute myocardial infarction (AMI) is uncommon, but can result in maternal and/or fetal death. This study retrospectively reviews pregnancy-related AMI reported from medical institutions in Japan. We electronically or manually searched the literature for reports of pregnancy-related AMI between 1981 and 2011. In total, 62 patients were described and the numbers increased in accordance with the rising average age of the mothers. AMI occurred frequently in women aged 30-34 years (mean age, 33), in the third trimester and postpartum (n=11 and n=28, respectively). The prevalence of conventional risk factors was relatively low (n=21). On the other hand, 29 patients had obstetric and/or non-obstetric complications, and 24 received medication. Only 8 AMI were caused by atherosclerosis, while coronary dissection, thrombus and spasm were the cause in 14, 9 and 12 cases, respectively. All patients with atherosclerosis had conventional risk factors, and some patients with spasm had a history of smoking. Medication with ergot derivatives was associated mostly with spasm, whereas ritodrine was potentially related to dissection. The prevalence of pregnancy-related AMI in Japan seems lower than in Western countries, and the etiology differs considerably. However, as the trend of later childbearing continues, more pregnant women have more risk factors, complications, and require medication. Cardiologists and obstetricians must consider the increased risk of AMI.

[Diagnosis of facial and craniofacial asymmetry].

PubMed

Arnaud, E; Marchac, D; Renier, D

2001-10-01

Craniofacial asymmetry is caused by various aetiologies but clinical examination remains the most important criteria since minor asymmetry is always present. The diagnosis can be confirmed by anthropometric measurements and radiological examinations but only severe asymmetries or asymmetries with an associated functional impairment should be treated. The treatment depends on the cause, and on the time of appearance. Congenital asymmetries might be treated early, during the first year of life if a craniosynostosis is present. Hemifacial microsomia are treated later if there is no breathing impairment. Since the pediatricians have recommended the dorsal position for infant sleeping, an increasing number of posterior flattening of the skull has been appearing, and could be prevented by adequate nursing. Other causes of craniofacial asymmetries are rare and should be adapted to the cause (tumors, atrophies, neurological paralysis, hypertrophies) by a specialized multidisciplinar team.

The major objectives of this project were to establish the pattern of basal hepatic bile flow and the effects of intravenous administration of cholecystokinin on the liver, sphincter of Oddi, and gallbladder, and to identify reliable parameters for the diagnosis of sphincter of Oddi spasm (SOS). Eight women with clinically suspected sphincter of Oddi spasm (SOS group), ten control subjects (control group), and ten patients who had recently received an opioid (opioid group) were selected for quantitative cholescintigraphy with cholecystokinin. Each patient was studied with 111-185 MBq (3-5 mCi) technetium-99m mebrofenin after 6-8 h of fasting. Hepatic phase images were obtained for 60 min, followed by gallbladder phase images for 30 min. During the gallbladder phase, 10 ng/kg octapeptide of cholecystokinin (CCK-8) was infused over 3 min through an infusion pump. Hepatic extraction fraction, excretion half-time, basal hepatic bile flow into the gallbladder, gallbladder ejection fraction, and post-CCK-8 paradoxical filling (>30% of basal counts) were identified. Seven of the patients with SOS were treated with antispasmodics (calcium channel blockers), and one underwent endoscopic sphincterotomy. Mean (+/-SD) hepatic bile entry into the gallbladder (versus GI tract) was widely variable: it was lower in SOS patients (32%+/-31%) than in controls (61%+/-36%) and the opioid group (61%+/-25%), but the difference was not statistically significant. Hepatic extraction fraction, excretion half-time, and pattern of bile flow through both intrahepatic and extrahepatic ducts were normal in all three groups. Gallbladder mean ejection fraction was 9%+/-4% in the opioid group; this was significantly lower (P<0.0001) than the values in the control group (54%+/-18%) and the SOS group (48%+/-29%). Almost all of the bile emptied from the gallbladder refluxed into intrahepatic ducts; it reentered the gallbladder after cessation of CCK-8 infusion (paradoxical gallbladder filling) in all

We identified de novo nonsense variants in KIDINS220/ARMS in three unrelated patients with spastic paraplegia, intellectual disability, nystagmus, and obesity (SINO). KIDINS220 is an essential scaffold protein coordinating neurotrophin signal pathways in neurites and is spatially and temporally regulated in the brain. Molecular analysis of patients' variants confirmed expression and translation of truncated transcripts similar to recently characterized alternative terminal exon splice isoforms of KIDINS220 KIDINS220 undergoes extensive alternative splicing in specific neuronal populations and developmental time points, reflecting its complex role in neuronal maturation. In mice and humans, KIDINS220 is alternative spliced in the middle region as well as in the last exon. These full-length and KIDINS220 splice variants occur at precise moments in cortical, hippocampal, and motor neuron development, with splice variants similar to the variants seen in our patients and lacking the last exon of KIDINS220 occurring in adult rather than in embryonic brain. We conducted tissue-specific expression studies in zebrafish that resulted in spasms, confirming a functional link with disruption of the KIDINS220 levels in developing neurites. This work reveals a crucial physiological role of KIDINS220 in development and provides insight into how perturbation of the complex interplay of KIDINS220 isoforms and their relative expression can affect neuron control and human metabolism. Altogether, we here show that de novo protein-truncating KIDINS220 variants cause a new syndrome, SINO. This is the first report of KIDINS220 variants causing a human disease. © The Author 2016.

Background Hemifacial atrophy (Parry-Romberg syndrome) is a relatively rare disease. The etiology of the disease is not clear. Some authors postulate its relation with limited scleroderma linearis. Linear scleroderma "en coup de sabre" is characterized by clinical presence of most commonly one-sided linear syndrome. In a number of patients, neurological affection is the medium of the disease. The treatment of both scleroderma varieties is similar to the treatment of limited systemic sclerosis. Case presentation We present two cases of a disease: a case of a 49-year-old woman with a typical image of hemifacial atrophy, without any changes of the nervous system and a case of a 33-year-old patient with an "en coup de sabre" scleroderma and with CNS tumor. Conclusion We described typical cases of a rare diseases, hemifacial atrophy and "en coup de sabre" scleroderma. In the patient diagnosed with Parry-Romberg syndrome, with Borrelia burgdoferi infection and with minor neurological symptoms, despite a four-year case history, there was a lack of proper diagnosis and treatment. In the second patient only skin changes without any neurological symptoms could be observed and only a precise neurological diagnosis revealed the presence of CNS tumor. PMID:19635150

Hymenoptera order includes bees, which have a stinging apparatus at the tail capable of delivering venom to the affected tissues. Myocardial infarction, acute renal failure, Necrotizing fasciitis, fatal infection and hemifacial asymmetry, are some of the unusual reactions reported following hymenoptera stings. This paper reports a case of bee sting in the right floor of the nose that mimicked an odontogenic infection affecting the upper lip, canine space and nasal cavity such as in cases of infection secondary to pulpal or periodontal pathology of the anterior teeth. After a thorough clinical and radiographic examination, odontogenic infection was discarded and the diagnosis of floor of the nose mucosal lysis and lip abscess secondary to a bee sting was made. This case was successfully managed with adequate incision, drainage and antibiotics without any further complication. There are several reports of unusual reactions following hymenoptera stings. However, just a few of them referred to infections of local reactions and none of them related to the anatomic location affected in the patient of the present case. Early diagnosis and treatment prevented infection dissemination and the likelihood of tissue necrosis as in previously reported cases of Necrotizing fasciitis.

AbobotulinumtoxinA (Dysport®) was distributed for many years in vials containing 500MU (D500). Recently a new 300MU vial (D300) was additionally introduced (introduction). We wanted to explore whether more differentiated package sizes allow for more economic use of Dysport® in a large neurological botulinum toxin (BT) outpatient clinic. The study followed a retrospective chart review design based on our digital BT therapy data bank. All patients receiving Dysport® exclusively in a constant dose during the observation period (introduction ± 7 months) were included. Economic calculations are based on Dysport® prices as officially advertised in Germany. Sharing of vials between patients was not allowed. Altogether 83 patients (51 with dystonia, 25 with spasticity, 3 with hemifacial spasm, 4 with other diagnoses) were included in this study. The total amount of BT used before and after introduction was 102525MU, the amount prescribed 138000MU and 116300MU (-21700MU, -15.7%), the costs €146103 and €125250 (-€ 20853, -14.3%). The price for D500 before and after introduction was €529.36, for D300 €339.71. The D500 price for 1MU before and after introduction is €1.0587, the D300 price for 1MU €1.1324 (+ €0.073, +7.0% against D500). More flexible packaging reduces drug costs for BT therapy considerably. Introducing smaller packaging sizes is technically possible and should be encouraged. Extra costs for registration and logistics are moderate. Further cost reductions may be possible by introduction of even smaller packaging sizes. They can be calculated based on our model.

Developmental neurotoxicity of pyrethroid insecticides in zebrafish embryos.

2010-01-01

Pyrethroid insecticides are one of the most commonly used residential and agricultural insecticides. Based on the increased use of pyrethroids and recent studies showing that pregnant women and children are exposed to pyrethroids, there are concerns over the potential for developmental neurotoxicity. However, there have been relatively few studies on the developmental neurotoxicity of pyrethroids. In this study, we sought to investigate the developmental toxicity of six common pyrethroids, three type I compounds (permethrin, resmethrin, and bifenthrin) and three type II compounds (deltamethrin, cypermethrin, and lambda-cyhalothrin), and to determine whether zebrafish embryos may be an appropriate model for studying the developmental neurotoxicity of pyrethroids. Exposure of zebrafish embryos to pyrethroids caused a dose-dependent increase in mortality and pericardial edema, with type II compounds being the most potent. At doses approaching the LC(50), permethrin and deltamethrin caused craniofacial abnormalities. These findings are consistent with mammalian studies demonstrating that pyrethroids are mildly teratogenic at very high doses. However, at lower doses, body axis curvature and spasms were observed, which were reminiscent of the classic syndromes observed with pyrethroid toxicity. Treatment with diazepam ameliorated the spasms, while treatment with the sodium channel antagonist MS-222 ameliorated both spasms and body curvature, suggesting that pyrethroid-induced neurotoxicity is similar in zebrafish and mammals. Taken in concert, these data suggest that zebrafish may be an appropriate alternative model to study the mechanism(s) responsible for the developmental neurotoxicity of pyrethroid insecticides and aid in identification of compounds that should be further tested in mammalian systems.

An apparatus for training of the human visual accommodation system is presented, specifically, useful for training a person to volitionally control his focus to his far point (normaly infinity) from a position of myopia due to functional causes. The functional causes could be due, for example, to a behavioral accommodative spasm or the effects of an empty field. The device may also be used to measure accommodation, the accommodation resting position and the near and far points of vision.

A 42-year-old woman with a history of aspirin-induced asthma was admitted with severe chest pain. Emergency coronary angiography revealed coronary artery spasms. The administration of vasodilators did not suppress the anginal symptoms, and the differential white blood cell count continued to show eosinophilia. The patient's symptoms of aspirin-induced asthma, eosinophilia and other allergic states led to the diagnosis of Churg-Strauss syndrome (CSS). After starting betamethasone therapy, the eosinophilia and cardiac symptoms rapidly disappeared. Although coronary vasospasms related to CSS are rare, the present case suggests that a differential white blood cell count should be obtained in patients with refractory coronary vasospasms.

This study is to investigate the compensatory intracranial venous pathways in parasagittal meningiomas (PSM) patients by virtual reality technology. A total of 48 PSM patients (tumor group) and 20 patients with trigeminal neuralgia and hemifacial spasm but without intracranial venous diseases (control group) were enrolled. All patients underwent 3D CE-MRV examination. The 3D reconstructed images by virtual reality technology were used for assessment of diameter and number of intracranial veins, tumor location, venous sinus invasion degree and collateral circulation formation. Diameter of bridging veins in posterior 1/3 superior sagittal sinus (SSS) in tumor group was significantly smaller than that of the control group (P < 0.05). For tumors located in mid 1/3 SSS, diameter of bridging veins and vein of Labbé (VL) in posterior 1/3 SSS decreased significantly (P < 0.05). For tumors located in posterior 1/3 SSS, bridging vein number and transverse sinus (TS) diameter significantly decreased while superficial Sylvian vein (SSV) diameter increased significantly (P < 0.05). Compared with tumor in posterior 1/3 SSS subgroup, number of bridging veins in the tumor in mid 1/3 SSS subgroup increased significantly (P < 0.05). Compared with control group, only the bridging vein number in anterior 1/3 SSS segment in invasion Type 3-4 tumor subgroup decreased significantly (P < 0.05). Diameter of TS and bridging veins in posterior 1/3 SSS segment in sinus invasion Type 5-6 tumor subgroup decreased significantly (P < 0.05). Compared with control group, only the diameter of VL and TS of collateral circulation Grade 1 tumor subgroup decreased significantly (P < 0.05) while in Grade 3 tumor subgroup, TS diameter decreased and SSV diameter increased significantly (P < 0.05). The intracranial blood flow is mainly drained through SSV drainage after SSS occlusion by PSM.

For tumors located in mid 1/3 SSS, diameter of bridging veins and vein of Labbé (VL) in posterior 1/3 SSS decreased significantly (P < 0.05). For tumors located in posterior 1/3 SSS, bridging vein number and transverse sinus (TS) diameter significantly decreased while superficial Sylvian vein (SSV) diameter increased significantly (P < 0.05). Compared with tumor in posterior 1/3 SSS subgroup, number of bridging veins in the tumor in mid 1/3 SSS subgroup increased significantly (P < 0.05). Compared with control group, only the bridging vein number in anterior 1/3 SSS segment in invasion Type 3-4 tumor subgroup decreased significantly (P < 0.05). Diameter of TS and bridging veins in posterior 1/3 SSS segment in sinus invasion Type 5-6 tumor subgroup decreased significantly (P < 0.05). Compared with control group, only the diameter of VL and TS of collateral circulation Grade 1 tumor subgroup decreased significantly (P < 0.05) while in Grade 3 tumor subgroup, TS diameter decreased and SSV diameter increased significantly (P < 0.05). Conclusions: The intracranial blood flow is mainly drained through SSV drainage after SSS occlusion by PSM. PMID:26550184

Purpose: To define clinical and dosimetric predictors of nonauditory adverse radiation effects after radiosurgery for vestibular schwannoma treated with a 12 Gy prescription dose. Methods: We retrospectively reviewed our experience of vestibular schwannoma patients treated between September 2005 and December 2009. Two hundred patients were treated at a 12 Gy prescription dose; 80 had complete clinical and radiological follow-up for at least 24 months (median, 28.5 months). All treatment plans were reviewed for target volume and dosimetry characteristics; gradient index; homogeneity index, defined as the maximum dose in the treatment volume divided by the prescription dose; conformity index; brainstem; andmore » trigeminal nerve dose. All adverse radiation effects (ARE) were recorded. Because the intent of our study was to focus on the nonauditory adverse effects, hearing outcome was not evaluated in this study. Results: Twenty-seven (33.8%) patients developed ARE, 5 (6%) developed hydrocephalus, 10 (12.5%) reported new ataxia, 17 (21%) developed trigeminal dysfunction, 3 (3.75%) had facial weakness, and 1 patient developed hemifacial spasm. The development of edema within the pons was significantly associated with ARE (p = 0.001). On multivariate analysis, only target volume is a significant predictor of ARE (p = 0.001). There is a target volume threshold of 5 cm3, above which ARE are more likely. The treatment plan dosimetric characteristics are not associated with ARE, although the maximum dose to the 5th nerve is a significant predictor of trigeminal dysfunction, with a threshold of 9 Gy. The overall 2-year tumor control rate was 96%. Conclusions: Target volume is the most important predictor of adverse radiation effects, and we identified the significant treatment volume threshold to be 5 cm3. We also established through our series that the maximum tolerable dose to the 5th nerve is 9 Gy.« less

Crotoxin is the main neurotoxin of South American rattlesnake Crotalus durissus terrificus. The neurotoxic action is characterized by a presynaptic blockade. The purpose of this research is to assess the ability of crotoxin to induce temporary paralysis of extraocular and facial muscles in humans. Doses of crotoxin used ranged from 2 to 5 units (U), each unit corresponding to one LD50. We first applied 2U of crotoxin in one of the extraocular muscles of 3 amaurotic individuals to be submitted to ocular evisceration. In the second stage, we applied crotoxin in 12 extraocular muscles of 9 patients with strabismic amblyopia. In the last stage, crotoxin was used in the treatment of blepharospasm in another 3 patients. No patient showed any systemic side effect or change in vision or any eye structure problem after the procedure. The only local side effects observed were slight conjunctival hyperemia, which recovered spontaneously. In 2 patients there was no change in ocular deviation after 2U crotoxin application. Limitation of the muscle action was observed in 8 of the 12 applications. The change in ocular deviation after application of 2U of crotoxin (9 injections) was in average 15.7 prism diopters (PD). When the dose was 4U (2 applications) the change was in average 37.5 PD and a single application of 5U produced a change of 16 PD in ocular deviation. This effect lasted from 1 to 3 months. Two of the 3 patients with blepharospasm had the hemifacial spasm improved with crotoxin, which returned after 2 months. This study provides data suggesting that crotoxin may be a useful new therapeutic option for the treatment of strabismus and blepharospasm. We expect that with further studies crotoxin could be an option for many other medical areas.

While hypertension is negatively associated with coronary artery spasm (CAS), scarce data are available on diabetes mellitus in relation to CAS. In addition, outcome prediction in patients with CAS is challenging due to the lack of appropriate biomarkers. Therefore, we sought to identify the roles that gender, high-sensitivity C-reactive protein (hs-CRP), diabetes mellitus and hypertension play in CAS development and prognosis. Patients (350 women and 547 men) undergoing diagnostic coronary angiography with or without proven CAS but without obstructive stenosis were evaluated at long-term follow-up (median 102 months). Diabetic women and diabetic men with low hs-CRP levels had a low and high risk of CAS (odds ratio [OR]: 0.16, 95% confidence interval [CI]: 0.01-1.88 and OR: 5.02, 95% CI: 1.03-24.54, respectively). The ORs of CAS in both women and men with the highest hs-CRP tertile (>3 mg/L) reduced from 4.41 to 1.45 and 2.98 to 1.52, respectively, if they had diabetes mellitus, and from 9.68 to 2.43 and 2.60 to 1.75, respectively, if they had hypertension. Hypertension had a more negative effect on CAS development in diabetic than non-diabetic women, which was not observed in men. The highest hs-CRP tertile was an independent predictor of adverse outcomes. Patients with the highest hs-CRP tertile had more coronary events than patients with the lowest hs-CRP tertitle (p = 0.021, log-rank test). Diabetes mellitus contributes to CAS development in men with low hs-CRP levels, but not in women. There are negative effects of diabetes mellitus and hypertension on CAS development in patients with high hs-CRP levels and especially in women. Elevated hs-CRP level independently predicts adverse outcomes.

Temporomandibular pain caused by sleep disorders: a review and case report.

Babiec, Daniel F

2017-01-01

Patients who present to the general dentist's office with complaints of temporomandibular joint pain may exhibit signs and symptoms such as muscle soreness, bruxism, joint soreness, limited range of movement, altered movement, and facial pain as well as tooth chipping or tooth movement. After examinations, radiographic evaluations, and a review of medical history, dentists may have a bias toward regarding these symptoms as oral or dental in origin. After a diagnosis of a temporomandibular disorder (TMD), bruxism, or muscular spasms due to occlusal instabilities is established, the treatment protocol often includes an oral appliance (such as a nightguard), exercises, and pharmacologic agents. However, patients with sleep-disordered breathing (SDB) can exhibit the same signs and symptoms as patients with TMDs, and these symptoms can be misinterpreted as being dental in origin. Dental treatment can actually worsen these medical conditions, putting patients at further risk for untreated and aggravated SDB along with its medical sequelae.

[Primary hiperoxaluria: a new mutation in gen AGXT (R197Q) cause of neonatal convulsions].

2008-12-01

Primary hyperoxaluria is a congenital innate error of the metabolism of the amino acids, that is transmitted like an autosomal recessive character. Two types of hyperoxaluria exist: the primary type I, that corresponds to the peroxisomal enzymatic deficit of the alanine glyoxylate aminotransferase in the liver (AGT) and type II, due to the deficit of the glyoxylate reductase/hydroxypyruvate reductase deficiency (GRHPR). The primary type I (AGT) is the most frequenty. We report the case of a female infant of one month of age, that on her first day post birth, presented myoclonic convulsions and tonic spasms, both during wakefullness and sleep periods, that became more frequent and did not respond to the use of anticonvulsants. The ictal Electroencephalogram presented an intermittent activity of spikes and spike-waves of high voltage in the right hemisphere. Eight minutes after the intravenous administration of 150 mg of pyridoxine, it was observed a diminution of the epileptic activity, as well as the clinical manifestations. The determination of organic acids in urine revealed an increase in the concentration levels of oxalic acid (3064 mmol/mol of creatinine). The molecular genetic study of the AGXT gene, showed the existence of a R197Q mutation in exón 5 of the patient and her father. She received treatment with pyridoxine at a dose of 50 mg/day. When she reached the age of three months both a normal electroencephalogram and biochemistry were obtained. Although it is a rare cause of neonatal convulsions, hyperoxaluria, due to new mutations is an underdiagnosed disease by neonatologists and paediatricias.

The mitochondrial DNA m.13513G>A mutation in the ND5 subunit gene is a frequent cause of Leigh syndrome. Patients harboring this mutation typically present with ptosis and cardiac conduction abnormalities, particularly Wolff-Parkinson-White syndrome, and have a late clinical onset, which contrasts with the typical infantile form. The authors describe a patient presenting with intrauterine growth retardation and visual impairment at 3 months of age, followed by infantile spasms, severe gastrointestinal dysmotility, and neurological regression. The patient had hyperlactacidemia and bilateral basal ganglia and brainstem lesions on MRI. Although he did not present cardiac conduction abnormalities, his mother had been diagnosed with Wolff-Parkinson-White syndrome. The m.13513G>A mutation was found in the patient's muscle and in several tissues of his mother. The present results expand the phenotype of Leigh syndrome associated with the m.13513G>A mutation, which should be suspected in patients with early-onset mitochondrial encephalopathy with infantile spasms or prominent gastrointestinal smooth muscle involvement.

Limbus Vertebra Presenting with Inflammatory Low Back Pain: A Case Report

Limbus vertebra is a condition characterized by marginal interosseous herniation of the nucleus pulposus, and causes non specific symptoms like low back pain, back pain, muscle spasms and radiculopathy. It is frequently confused with vertebral fracture, infection, schmorl nodule or tumour because it has not a spesific symptom. It usually causes mechanical low back pain rather than inflammatory low back pain. We reported a patient presented with inflammatory low back pain and diagnosed with anterior limbus vertebra because it is rare and the patient has atypical clinical presentation. PMID:27134989

At present it is rather well-established that primary trigeminal neuralgia, hemifacial spasm and vago-glossopharyngeal neuralgia have as one of the main causes a vascular compression. The strong correlations found between the lengths and volumes of the central myelin portions of the nerves and the incidences of the corresponding diseases is a plea for the role played by this anatomical region in the mechanism of these diseases.

Efficacy and safety of guaifenesin for upper back, neck, and shoulder pain: a Phase II proof-of-concept, multicenter, placebo-controlled, repeat-dose, parallel-group study.

Guaifenesin, an over-the-counter (OTC) expectorant, has exhibited muscle relaxant effects preclinically and clinically. This proof-of-principle study explored whether OTC doses of guaifenesin can provide relief from acute upper back, neck, or shoulder muscle spasm and pain. This multicenter, placebo-controlled, repeat-dose, parallel study randomly assigned adults experiencing acute pain and muscle spasm in their upper back, neck, or shoulder to guaifenesin 600 or 1200 mg or matched placebo twice daily (BID) in a 2:2:1:1 ratio for 7 days. The primary end point was the change from baseline in muscle spasm relief, measured using an 11-point numeric rating scale (0=not present to 10=unbearable) recorded twice daily and averaged over the 7-day treatment period. Analyses were performed using a linear mixed model that included treatment as a fixed effect and site as a random effect. A total of 77 subjects were included in the 4 treatment groups. Least squares mean muscle spasm score over 7 days was 1.77 with guaifenesin 1200 mg, 1.42 with its matched placebo, 1.53 with guaifenesin 600 mg, and 1.74 with its matched placebo. Treatment with guaifenesin 1200 mg BID provided 25% greater reduction in mean muscle spasm over its matched placebo and 16% greater reduction than guaifenesin 600 mg BID. These differences were not statistically significant. Based on comparisons of absolute mean values, a consistent directional change in effect was observed, suggesting some benefit from placebo to lower-to-upper doses of guaifenesin with regard to muscle spasm, tension, pain, discomfort, and relaxation. No severe or serious adverse events were reported. Results suggest the potential for OTC dose of guaifenesin 1200 mg BID to provide symptomatic relief of upper back musculoskeletal pain and spasm. Confirmation of this preliminary result in a larger, adequately powered study is needed.

There is a great need for safe and effective therapies for treatment of infantile spasms (IS) and Lennox-Gastaut syndrome (LGS). Based on anecdotal reports and limited experience in an open-label trial, cannabidiol (CBD) has received tremendous attention as a potential treatment for pediatric epilepsy, especially Dravet syndrome. However, there is scant evidence of specific utility for treatment of IS and LGS. We sought to document the experiences of children with IS and/or LGS who have been treated with CBD-enriched cannabis preparations. We conducted a brief online survey of parents who administered CBD-enriched cannabis preparations for the treatment of their children's epilepsy. We specifically recruited parents of children with IS and LGS and focused on perceived efficacy, dosage, and tolerability. Survey respondents included 117 parents of children with epilepsy (including 53 with IS or LGS) who had administered CBD products to their children. Perceived efficacy and tolerability were similar across etiologic subgroups. Eighty-five percent of all parents reported a reduction in seizure frequency, and 14% reported complete seizure freedom. Epilepsy was characterized as highly refractory with median latency from epilepsy onset to CBD initiation of five years, during which the patient's seizures failed to improve after a median of eight antiseizure medication trials. The median duration and the median dosage of CBD exposure were 6.8 months and 4.3mg/kg/day, respectively. Reported side effects were far less common during CBD exposure, with the exception of increased appetite (30%). A high proportion of respondents reported improvement in sleep (53%), alertness (71%), and mood (63%) during CBD therapy. Although this study suggests a potential role for CBD in the treatment of refractory childhood epilepsy including IS and LGS, it does not represent compelling evidence of efficacy or safety. From a methodological standpoint, this study is extraordinarily vulnerable

African tick bite fever (ATBF) caused by Rickettsia africae is an emerging health problem in travellers to sub-Saharan Africa. We here present 6 patients with evidence of long-lasting sub-acute neuropathy following ATBF contracted during safari trips to southern Africa. Three patients developed radiating pain, paresthaesia and/or motor weakness of extremities, 2 had hemi-facial pain and paresthaesia, and 1 developed unilateral sensorineural hearing loss. When evaluated 3-26 months after symptom onset, cerebrospinal fluid samples from 5 patients were negative for R. africae PCR and serology, but revealed elevated protein content in 3 and mild pleocytosis in 1 case. Despite extensive investigations, no plausible alternative causes of neuropathy could be identified. Treatment with doxycycline in 2 patients had no clinical effect. Given the current increase of international safari tourism to sub-Saharan Africa, more cases of sub-acute neuropathy following ATBF may well be encountered in Europe and elsewhere in the y to come.

Parry-Romberg syndrome (PRS) is a relatively rare degenerative disorder that is poorly understood. PRS is characterized by slowly progressing atrophy affecting one side of the face, and is frequently associated with localized scleroderma, especially linear scleroderma, which is known as en coup de sabre. This is a report of the author's experiences with PRS accompanying en coup de sabre, and a review of the ongoing considerable debate associated with these two entities. Case 1 was a 37-year-old woman who had right hemifacial atrophy with unilateral en coup de sabre for seven years. Fat grafting to her atrophic lip had been conducted, and steroid injection had been performed on the indurated plaque of the forehead. Case 2 was a 29-year-old woman who had suffered from right hemifacial atrophy and bilateral en coup de sabre for 18 years. Surgical corrections such as scapular osteocutaneous flap and mandible/maxilla distraction showed unsatisfying results.

Facial synkinesis (or synkinesia) (FS) occurs frequently after paresis or paralysis of the facial nerve and is in most cases due to aberrant regeneration of (branches of) the facial nerve. Patients suffer from inappropriate and involuntary synchronous facial muscle contractions. Here we describe two cases of sound-induced facial synkinesis (SFS) after facial nerve injury. As far as we know, this phenomenon has not been described in the English literature before. Patient A presented with right hemifacial palsy after lesion of the facial nerve due to skull base fracture. He reported involuntary muscle activity at the right corner of the mouth, specifically on hearing ringing keys. Patient B suffered from left hemifacial palsy following otitis media and developed involuntary muscle contraction in the facial musculature specifically on hearing clapping hands or a trumpet sound. Both patients were evaluated by means of video, audio and EMG analysis. Possible mechanisms in the pathophysiology of SFS are postulated and therapeutic options are discussed.

Mutations of the X-linked gene cyclin-dependent kinase-like 5 (CDKL5) cause an X-linked encephalopathy with early onset intractable epilepsy, including infantile spasms and other seizure types, and a Rett syndrome (RTT)-like phenotype. Very limited information is available on the frequency and phenotypic spectrum associated with CDKL5 deletions/duplications. We investigated the role of CDKL5 deletions/duplications in causing early onset intractable epilepsy of unknown etiology in girls. We studied 49 girls with early onset intractable epilepsy, with or without infantile spasms, and developmental impairment, for whom no etiologic factors were obvious after clinical examination, brain magnetic resonance imaging (MRI) and expanded screening for inborn errors of metabolism. We performed CDKL5 gene mutation analysis in all and multiplex ligation dependent probe amplification assay (MLPA) in those who were mutation negative. Custom Array-comparative genomic hybridization (CGH), breakpoint polymerase chain reaction (PCR) analysis, and X-inactivation studies were performed in patients in whom MLPA uncovered a genomic alteration. We found CDKL5 mutations in 8.2% (4 of 49) of patients and genomic deletions in 8.2% (4 of 49). Overall, abnormalities of the CDKL5 gene accounted for 16.3% (8 of 49) of patients. CDKL5 gene deletions are an under-ascertained cause of early onset intractable epilepsy in girls. Genetic testing of CDKL5, including both mutation and deletion/duplication analysis, should be considered in this clinical subgroup.

Muscular spasm is a frequent symptom which is difficult to record precisely. On the basis of literature on the subject and of own studies, we undertook to describe various methods of examination which could be used to demonstrate such changes. Up to now, palpation is still the most important and most exact method for the experienced examiner. In this way local as well as extended muscular spasms can be made evident. The disadvantage however is the lack of objective proof. The easy-to-use Tissue-Compliance-Meter of Fischer, which measures the consistency of soft tissue, documents the intraindividual difference rather than the interindividual difference. This is due to the individually variable thickness of the subcutaneous fatty tissue. However, on the whole there is a good correlation to the findings of palpation. The pendulous-test and badismography allow especially the conclusion with regard to unilateral changes of tonus in the gluteal and upper leg muscles. This method also very well suits the intraindividual comparison, but less so the interindividual one. The continuous electromyogram is able to show the enhanced activity in spasmotic muscles also during sleep. The evaluation of enhanced muscle activity remains uncertain when using plain electromyogram. Recording of muscle tissue oxygen pressure is of little use to evaluate muscle spasm. Nonetheless, it provides interesting insights into pathogenetic questions. Thermography, measuring the blood circulation at the skin surface, is especially suited for perceiving intraindividual differences in case of muscle spasm. Nuclear magnetic resonance spectroscopy allows for noninvasive pH measurements in the muscle and therewith renders certain data concerning the degree of tension of this tissue. It is not yet suited for routine examination. The value of positron emission tomography for registering muscle spasm remains uncertain. Hopefully, this method, which documents the muscle energy metabolism, will enable us to

Increased anal basal pressure in chronic anal fissures may be caused by overreaction of the anal-external sphincter continence reflex.

Chronic anal fissure is a painful disorder caused by linear ulcers in the distal anal mucosa. Even though it counts as one of the most common benign anorectal disorders, its precise etiology and pathophysiology remains unclear. Current thinking is that anal fissures are caused by anal trauma and pain, which leads to internal anal sphincter hypertonia. Increased anal basal pressure leads to diminished anodermal blood flow and local ischemia, which delays healing and leads to chronic anal fissure. The current treatment of choice for chronic anal fissure is either lateral internal sphincterotomy or botulinum toxin injections. In contrast to current thinking, we hypothesize that the external, rather than the internal, anal sphincter is responsible for increased anal basal pressure in patients suffering from chronic anal fissure. We think that damage to the anal mucosa leads to hypersensitivity of the contact receptors of the anal-external sphincter continence reflex, resulting in overreaction of the reflex. Overreaction causes spasm of the external anal sphincter. This in turn leads to increased anal basal pressure, diminished anodermal blood flow, and ischemia. Ischemia, finally, prevents the anal fissure from healing. Our hypothesis is supported by two findings. The first concerned a chronic anal fissure patient with increased anal basal pressure (170mmHg) who had undergone lateral sphincterotomy. Directly after the operation, while the submucosal anesthetic was still active, basal anal pressure decreased to 80mmHg. Seven hours after the operation, when the anesthetic had completely worn off, basal anal pressure increased again to 125mmHg, even though the internal anal sphincter could no longer be responsible for the increase. Second, in contrast to previous studies, recent studies demonstrated that botulinum toxin influences external anal sphincter activity and, because it is a striated muscle relaxant, it seems reasonable to presume that it affects the striated

Management of tetanus complication

The mortality rate of tetanus is still high; it is because of various complications due to muscle spasms, autonomic dysfunction, as well as due to prolonged critical care. Management of tetanus with its complications is in intensive care facilities. Management goals include stopping toxin production, neutralization of unbound toxin, management of the airway, muscle spasm control, treatment of autonomic dysfunction and general supportive management. Currently, diazepam is still an effective medication to control of muscle spasm and rigidity. Therapy for autonomic dysfunction that supported by evidence is MgSO4. Also, general supportive management for long-term care remains necessary to prevent other complications such as thromboembolism, infection, malnutrition, and others.

Diagnostic yield of 24-hour esophageal manometry in non-cardiac chest pain.

In the past, ambulatory 24-h manometry has been shown useful for the evaluation of patients with non-cardiac chest pain (NCCP). With the diagnostic improvements brought by pH-impedance monitoring and high-resolution manometry (HRM), the contribution of ambulatory 24-h manometry to the diagnosis of esophageal hypertensive disorders has become uncertain. Our aim was to assess the additional diagnostic yield of ambulatory manometry to HRM and ambulatory pH-impedance monitoring in this patient population. All patients underwent 24-h ambulatory pressure-pH-impedance monitoring and HRM. Patients had retrosternal pain as a predominant symptom and no explanation after cardiologic and digestive endoscopic evaluations. Diagnostic measurements were analyzed by two independent physicians. Fifty-nine patients met the inclusion criteria; 37.3% of the patients had their symptoms explained by abnormalities on pH-impedance monitoring and 6.8% by ambulatory manometry. Functional chest pain was diagnosed in 52.5% of the patients. High-resolution manometry, using the Chicago Classification v3.0 criteria alone, did not identify any of the four patients with esophageal spasm on ambulatory manometry. However, taking into account other abnormalities, such as simultaneous (rapid) or repetitive contractions, HRM had a sensitivity of 75% and a specificity of 98.2% for the diagnosis of esophageal spasm. In the work-up of NCCP, ambulatory 24-h manometry has a low additional diagnostic yield. However, it remains the best technique to identify esophageal spasm as the cause of symptoms. This is particularly useful when an unequivocal diagnosis is needed before treatment. © 2016 John Wiley & Sons Ltd.

Proctalgia fugax is a benign condition characterized by paroxysms of anorectal pain in the absence of identifiable anorectal lesions. The cause is unknown but may involve spasm of smooth or striated muscle. Surveys indicate the disorder is common in the general population, with only a minority of victims seeking medical attention. There is no universally accepted treatment for proctalgia fugax. The diagnosis is established by the typical history and the exclusion of other pelvic and anorectal abnormality.

Twenty seven children who had been diagnosed as having idiopathic chest pain were investigated to find out if the pain was of gastrointestinal origin. The symptoms had lasted from two weeks to eight months. In 21 of the 27 children (78%) the chest pain had a gastrointestinal cause: 16 had oesophagitis, four had gastritis, and one had diffuse oesophageal spasm. All patients responded to medical treatment of their gastrointestinal symptoms, resulting in disappearance of the chest pain. PMID:3232993

Successful management of vaginismus: An eclectic approach.

Vaginismus is defined as recurrent or persistent involuntary spasm of the musculature of the outer third of the vagina, which interferes with coitus and causes distress and interpersonal difficulty. In this report, we describe the successful treatment of vaginismus in a 25-year-old lady based on a model proposed by Keith Hawton. The eclectic approach involved education, graded insertion of fingers, Kegel's exercises and usage of local anesthesia with vaginal containment along with the prescription of Escitalopram.

Nutcracker esophagus (NE), Jackhammer esophagus (JHE), distal esophageal spasm (DES), and hypertensive lower esophageal sphincter (HTLES) are defined by esophageal manometric findings. Some patients with these esophageal motility disorders also have abnormal gastroesophageal reflux. It is unclear to what extent these patients' symptoms are caused by the motility disorder, the acid reflux, or both. The aim of this study was to determine the effectiveness of laparoscopic Nissen fundoplication (LNF) on esophageal motility disorders, gastroesophageal reflux, and patient symptoms. Between 2007 and 2013, we performed high-resolution esophageal manometry on 3400 patients, and 221 patients were found to have a spastic esophageal motility disorder. The medical records of these patients were reviewed to determine the manometric abnormality, presence of gastroesophageal symptoms, and amount of esophageal acid exposure. In those patients that underwent LNF, we compared pre- and postoperative esophageal motility, gastroesophageal symptom severity, and esophageal acid exposure. Of the 221 patients with spastic motility disorders, 77 had NE, 2 had JHE, 30 had DES, and 112 had HTLES. The most frequently reported primary and secondary symptoms among all patients were: heartburn and/or regurgitation, 69.2%; respiratory, 39.8%; dysphagia, 35.7%; and chest pain, 22.6%. Of the 221 patients, 192 underwent 24-hour pH monitoring, and 103 demonstrated abnormal distal esophageal acid exposure. Abnormal 24-hour pH monitoring was detected in 62% of patients with heartburn and regurgitation, 49% of patients with respiratory symptoms, 36.8 % of patients with dysphagia, and 32.6% of patients with chest pain. Sixty-six of the 103 patients with abnormal 24-hour pH monitoring underwent LNF. Thirty-eight (13NE, 2JHE, 6 DES, and 17 HTLES) of these 66 patients had a minimum of 6-month postoperative follow-up that included clinical evaluation, esophageal manometry, and 24-hour pH monitoring

Possible induction of West syndrome by oxcarbazepine therapy in a patient with complex partial seizures.

PubMed

Veerapandiyan, Aravindhan; Singh, Piyush; Mikati, Mohamad A

2012-03-01

Oxcarbazepine has been reported to precipitate myoclonic, generalised tonic-clonic, absence, and complex partial seizures, and carbamazepine to precipitate absences, myoclonic seizures and spasms. Here, we report a one-year, six-month-old girl with complex partial seizures who developed infantile spasms, developmental regression, and hypsarrhythmia during the two weeks directly following initiation of oxcarbazepine (14 mg/kg/day). All of these resolved within a few days after discontinuation of this medication. Although we cannot rule out that the above association may have been coincidental, or that the improvement may have been due to concurrent therapy, this case raises the possibility that oxcarbazepine, like carbamazepine, may precipitate infantile spasms and West syndrome.

Disfigurement of the face caused by postburn scars, resected congenital nevi and vascular malformations has both functional and psychological consequences. Ideal reconstruction of the facial components requires producing not only function but also the better appearance of the face. The skin of the neck, supraclavicular or cervicothoracic regions are the most commonly used and the most likely source of skin for facial reconstruction in those techniques which prefabrications with tissue expansion are used. This retrospective cohort study describes the two staged prelaminated temporoparietal fascia flap which eliminates the usage of tissue expansion by using skin graft harvested from the neck and occipital region and the application of this flap for the lower three-fourths of the face. 5 patients received prelaminated temporoparietal fascia flap without tissue expansion for facial resurfacing. The mean age at surgery was 39, 2 years (range, 17-60 years). The average follow up was 21.6 months (range, 10-48 months). The size of the raised prelaminated temporoparietal fascia flaps ranged from 9 × 8 cm to 14 × 10 cm. All flaps survived after second stage. Varied degrees of venous congestion were observed after flap insets in all cases but none required any further treatment for the congestion. The entire lesion could not be resected due to the large size of the lesion in all patients. Two stage prelaminated temporoparietal fascia flap with skin graft is an effective technique for the reconstruction of partial facial defects in selected patients. It is simple, quick, safe and reliable, and requires no expansion of skin or no microsurgery. Copyright © 2017 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Summary Surgery on the head and neck region may be complicated by vascular trauma, caused by direct injury on the vascular wall. Lesions of the arteries are more dangerous than the venous one. The traumatic lesion may cause laceration of the artery wall, spasm, dissection, arteriovenous fistula, occlusion or pseudoaneurysm. We present a case of a child with a giant ICA pseudoaneurysm after tonsillectomy, manifested by pulsing mass and respiratory distress, which was treated by endovascular approach, occluding the lesion and the proximal artery with Histoacryl. We reinforce that the endovascular approach is the better way to treat most of the traumatic vascular lesions. PMID:20594516

Magnesium sulphate for treatment of tetanus in adults.

PubMed

Mathew, P J; Samra, T; Wig, J

2010-01-01

There are reports that suggest that magnesium sulphate alone may control muscle spasms thereby avoiding sedation and mechanical ventilation in tetanus, but this has not been confirmed. We examined the efficacy and safety of intravenous magnesium sulphate for control of rigidity and spasms in adults with tetanus. A prospective clinical study of intravenous magnesium sulphate was carried out over a period of two years in a tertiary care teaching hospital. In addition to human tetanus immunoglobulin and parenteral antibiotics, patients with tetanus received magnesium sulphate 70 mg/kg intravenously followed by infusion. The infusion was increased by 0.5 g/hour every six hours until cessation of spasms or abolishment of patellar tendon jerk. The primary outcome measure was efficacy determined by control of spasms. Secondary outcomes included frequency of autonomic instability, duration of ventilatory support, hospital stay and mortality. Thirty-three patients were enrolled. At presentation, the incidence of severity of tetanus was as follows: Grade I: 5 (15%), Grade II: 13 (39%), Grade III: 14 (42%) and Grade IV: 1 (3%). Rigidity and mild spasms were controlled with magnesium therapy alone in six patients; all were Grades I or II. Additional sedatives were required in severe forms of tetanus. The average duration of ventilatory support was 18.3 +/- 16.0 days and the overall mortality was 22.9%. Asymptomatic hypocalcaemia was a universal finding. Magnesium sulphate therapy alone may not be efficacious for the treatment of severe tetanus.

Objective Benign Essential Blepharospasm (BEB) and hemifacial spasm (HFS) are the most common hyperkinetic movement disorders of facial muscles. Although similar in clinical presentation different pathophysiological mechanisms are assumed. Botulinum Neurotoxin (BoNT) is a standard evidence-based treatment for both conditions. In this study we aimed to assess grey matter microstructural differences between these two groups of patients and compared them with healthy controls. In patients we furthermore tracked the longitudinal morphometric changes associated with BoNT therapy. We hypothesized microstructural differences between the groups at the time point of maximum symptoms representation and distinct longitudinal grey matter dynamics with symptom improvement. Methods Cross-sectional and longitudinal analyses of 3T 3D-T1 MRI images from BEB, HFS patients prior to and one month after BoNT therapy and from a group of age and sex matched healthy controls. Cortical thickness as extracted from Freesurfer was assessed as parameter of microstructural integrity. Results BoNT therapy markedly improved motor symptoms in patients with BEB and HFS. Significant differences of grey matter integrity have been found between the two patients groups. The BEB group showed lower cortical thickness at baseline in the frontal-rostral, supramarginal and temporal regions compared to patients with HFS. In this group BoNT treatment was associated with a cortical thinning in the primary motor cortex and the pre-supplementary motor area (pre-SMA). Contrary patients with HFS showed no longitudinal CT changes. A decreased cortical thickness was attested bilaterally in the temporal poles and in the right superior frontal region in BEB patients in comparison to HC. Patients in the HFS group presented a decreased CT in the left lingual gyrus and temporal pole. Conclusions Although patients with BEB and HFS present clinically with involuntary movements of facial muscles, they exhibited differences

Cyclin-dependent kinase-like 5 (CDKL5) gene abnormalities cause an early-onset epileptic encephalopathy. We performed video-electroencephalography (video-EEG) monitoring early in the course of CDKL5-related epileptic encephalopathy in order to examine the early electroclinical characteristics of the condition. We used video-EEG to monitor six infants (five females, one male) with CDKL5-related epileptic encephalopathy (five mutations; one deletion), at ages 45 days to 12 months and followed them up to the ages of 14 months to 5 years (mean age 23 mo). We focused our analysis on the first year of life. The results were evaluated against those of a comparison group of nine infants (aged below 1y) with epileptic encephalography who had tested negative for CDKL5 mutations and deletions. One infant exhibited normal background activity, three exhibited moderate slowing, and two exhibited a suppression burst pattern. Two participants had epileptic spasms and four had a stereotyped complex seizure pattern, which we defined as a 'prolonged' generalized tonic-clonic event consisting of a tonic-tonic/vibratory contraction, followed by a clonic phase with series of spasms, gradually translating into repetitive distal myoclonic jerks. Seizure duration ranged from 2 to 4 minutes. The EEG correlate of each clinical phase included an initial electrodecremental event (tonic vibratory phase), irregular series of sharp waves and spike slow waves (clonic phase with series of spasms), and bilateral rhythmic sharp waves (time locked with myoclonus). Infants with CDKL5-related early epileptic encephalopathy can present in the first year of life with an unusual electroclinical pattern of 'prolonged' generalized tonic-clonic seizures. © The Authors.

Post-Flight Back Pain Following International Space Station Missions: Evaluation of Spaceflight Risk Factors

NASA Technical Reports Server (NTRS)

Laughlin, Mitzi S.; Murray, Jocelyn D.; Wear, Mary L.; Van Baalen, Mary

2016-01-01

Back pain during spaceflight has often been attributed to the lengthening of the spinal column due to the absence of gravity during both short and long-duration missions. Upon landing and re-adaptation to gravity, the spinal column reverts back to its original length thereby causing some individuals to experience pain and muscular spasms, while others experience no ill effects. With International Space Station (ISS) missions, cases of back pain and injury are more common post-flight, but little is known about the potential risk factors.

Persistent pseudomyopia following a whiplash injury in a previously emmetropic woman.

Accommodative spasm, which manifests as ciliary muscle spasm, convergent strabismus or miosis, is a recognised consequence of head trauma. In whiplash cases, cervical spine hyperextension poses a risk of contra-coup injury and brainstem trauma, and is known to affect the visual system. However, to date, no cases of accommodative spasm due to whiplash injury have been reported. We present the case of a 34-year-old female who developed sudden onset blurred distance vision after a rear impact car crash, having previously been emmetropic. Her unaided distance visual acuity was 20/70 in the right eye and 20/20 in the left. Best-corrected visual acuity in the right eye was 20/20 with a correction that progressed from -1.75 to -3.50 DS over the 12 months following the accident.This patient's sudden unilateral myopia, with unilaterally increased amplitude of accommodation suggests pseudomyopia due to accommodative spasm. Magnetic resonance imaging showed no evidence of injury to her brain stem, frontal lobes or oculomotor nerve. The patient is now well adjusted with a -3.50DS corrective lens for the right eye. The accommodation reflex is susceptible to injury at the occipital lobe, frontal eye fields, Edinger-Westphal nuclei and oculomotor nerves. As such it should be examined in patients who present with visual disturbances following whiplash injury.It is important that such cases are identified at presentation, as early intervention can improve outcomes in accommodative spasm and reduce the long term psychological effects often associated with whiplash injuries.

To assess function and prevalence of spasms and trigger points of the pelvic floor muscles in women with deep endometriosis. One hundred and four (104) patients were assessed. Group 1 (G1) was composed of 52 subjects diagnosed with deep endometriosis proven by magnetic resonance imaging (MRI); Group 2 (G2) was composed of 52 women with no signs of endometriosis. Subjects from both G1 and G2 were seen at the Division of Pelvic Pain and Endometriosis and at Center for Prevention of Sexually Transmitted Diseases, both at Federal University of São Paulo (UNIFESP), respectively. A full physical therapy evaluation was carried out, including medical history, presence of dyspareunia and physical examination, which included detailed evaluation of pelvic floor muscles and occurrence of muscle spasm, trigger point and muscle function. The average age of the subjects in the study group was 36.4 and 30.9 years in the control group (p = 0.002). A greater prevalence of deep dyspareunia was found in the subjects in the endometriosis group when compared to the control group (p = 0.010). Women in G1 had higher prevalence of muscle spasms. In this group, 53.9 % had spasms-compared to only 17.3 % of women in G2 (p < 0.001). On the other hand, no significant difference between the groups (p = 0.153) was found while searching for the presence of trigger points. Women with deep endometriosis have increased prevalence of pelvic floor muscle spasms when compared to the control group.

We present a case of accidental injection of tranexamic acid during spinal anesthesia for an elective cesarean delivery. Immediately following intrathecal injection of 2mL of solution, the patient complained of severe back pain, followed by muscle spasm and tetany. As there was no evidence of spinal block, the medications given were checked and a 'used' ampoule of tranexamic acid was found on the spinal tray. General anesthesia was induced but muscle spasm and tetany persisted despite administration of a non-depolarizing muscle relaxant. Hemodynamic instability, ventricular tachycardia, and status epilepticus developed, which were refractory to phenytoin, diazepam, and infusions of thiopental, midazolam and amiodarone. Magnesium sulfate was administered postoperatively in the intensive care unit, following which the frequency of seizures decreased, eventually stopping. Unfortunately, on postoperative day three the patient died from cardiopulmonary arrest after an oxygen supply failure that was not associated with the initial event. This report underlines the importance of double-checking medications before injection in order to avoid a drug error. As well, it suggests that magnesium sulfate may be useful in stopping seizures caused by the intrathecal injection of tranexamic acid. Copyright © 2015 Elsevier Ltd. All rights reserved.

1983-09-01

Three children presented with low back pain radiating to the leg and with spasm of the hamstring and paravertebral muscles. Since the pain could not be ascribed to trauma, it was necessary to exclude the presence of infection or tumors. All the signs--localization of the pain, tenderness on one side of the back, X-ray film findings of unilateral or bilateral spondylolysis, and localized positive bone scan--pointed to spondylolysis as the cause of pain. All three children exhibited symptoms resembling those found in the facet syndrome described by Mooney and Robertson.

The best-defined primary esophageal motor disorder is achalasia. However, symptoms such as dysphagia, regurgitation and chest pain can be caused by other esophageal motility disorders. The Chicago classification introduced new manometric parameters and better defined esophageal motility disorders. Motility disorders beyond achalasia with the current classification are: esophagogastric junction outflow obstruction, major disorders of peristalsis (distal esophageal spasm, hypercontractile esophagus, absent contractility) and minor disorders of peristalsis (ineffective esophageal motility, fragmented peristalsis). The aim of this study was to review the current diagnosis and management of esophageal motility disorders other than achalasia.

Consideration of genetic contributions to the risk for spasmodic dysphonia.

PubMed

Sharma, Nutan; Franco, Ramon A

2011-09-01

Spasmodic dysphonia, a form of the neurologic condition known as dystonia, results from involuntary spasms of the larynx, producing interruptions of speech and changes in voice quality. The pathogenesis of spasmodic dysphonia is not well understood. However, several genetic mutations have been identified that cause different forms of dystonia. In some individuals, these genetic mutations result in spasmodic dysphonia, either with no other signs of dystonia or as part of a broader dystonia phenotype. Thus, research in the growing field of dystonia genetics may help to inform our understanding of the pathogenesis of spasmodic dysphonia.

A prospective study was made of 73 patients presenting in one year with abdominal pain provisionally diagnosed as of spinal origin. The criteria for audit of diagnosis and treatment are defined. The diagnosis was confirmed in 53 patients, 49 of whom had been treated with a lignocaine intercostal block in the relevant segment. Thirty-three of these (67.3%) had both complete and prolonged relief. It is suggested that the block causes interruption of a vicious circle of pain and muscle spasm in a 'spinal reflex pain syndrome'. PMID:860866

2012-01-01

Subacute sclerosing panencephalitis (SSPE) is a slowly progressive inflammatory disease of the central nervous system caused by a persistent measles virus usually affecting the childhood and adolescent age group. Clinical features at onset are very subtle and non-specific. Certain atypical features can occur at onset or during the course of illness which can be misleading. Neuroimaging features often are non-specific. Features like myoclonic jerks, cognitive decline and typical EEG findings lead to a strong suspicion of SSPE. Here, we describe the stagewise progression of a case of SSPE in a 14-year-old girl who had myoclonic jerks and cognitive decline at onset. During the course of disease, the patient developed cortical vision loss, atypical extrapyramidal features like segmental and hemifacial dystonia ultimately leading to a bedbound vegetative state. EEG showed typical periodic discharges along with positive cerebrospinal fluid serology for measles. PMID:23266775

The aim of this report is to investigate the possible causes of acute acquired onset of transient esotropia (AATE) in children and to help to differentiate ophthalmoplegic migraine (OM) from accommodative spasm (AS). A case of an 8-year-old Caucasian female affected by AATE and diplopia is described. The day before AATE onset, the patient complained of slight headache without nausea and vomiting, with spontaneous resolution. AATE diagnosis is challenging. The most likely ophthalmological causes of AATE are AS and OM. In these cases it is important to evaluate the presence of both a familial history of recurrent headaches and an AATE associated with migraine, ptosis, nausea, and vomiting. A full ophthalmological evaluation and a thorough refractive examination in cycloplegia are mandatory to exclude ophthalmological causes. PMID:28559837

To explore the improvement of hand motion function,spasm and self-care ability of daily life for stroke patients treated with floating-needle combined with rehabilitation training. Eighty hand spasm patients of post-stroke within one year after stroke were randomly divided into an observation group and a control group, 40 cases in each one. In the two groups, rehabilitation was adopted for eight weeks,once a day,40 min one time. In the observation group, based on the above treatment and according to muscle fascia trigger point, 2~3 points in both the internal and external sides of forearm were treated with floating-needle. The positive or passive flexion and extension of wrist and knuckle till the relief of spasm hand was combined. The floating-needle therapy was given for eight weeks, on the first three days once a day and later once every other day. Modified Ashworth Scale(MAS), activity of daily life(ADL, Barthel index) scores and Fugl-Meyer(FMA) scores were used to assess the spasm hand degree,activity of daily life and hand motion function before and after 7-day, 14-day and 8-week treatment. After 7-day, 14-day and 8-week treatment, MAS scores were apparently lower than those before treatment in the two groups(all P<0. 05), and Barthel scores and FMA scores were obviously higher than those before-treatment(all P<0. 05). After 14-day and 8-week treatment, FMA scores in the observation group were markedly higher than those in the control group(both P<0. 05). Floating-needle therapy combined with rehabilitation training and simple rehabilitation training could both improve hand spasm degree, hand function and activity of daily life of post-stroke patients, but floating-needle therapy combined with rehabilitation training is superior to simple rehabilitation training for the improvement of hand function.

Diagnosis and management of Bell's palsy.

Bell's palsy (BP) is an idiopathic peripheral facial nerve paralysis of sudden onset. Its most alarming symptom is unilateral facial weakness, which can result in the inability to close the eyelids, smile, or whistle. The pathogenesis of BP is controversial and is believed to be caused by inflammation of the facial nerve at the geniculate ganglion. Many viruses, especially herpes simplex and herpes zoster, have been suggested as initiators of this inflammatory process; however, this has not been proven. This report describes the case of a 14-year-old girl with right hemifacial palsy who sought treatment one month after the onset of palsy. The patient experienced a satisfactory recovery within 30 days of treatment and has maintained a stable physical outcome after 15 months of follow-up. Early treatment based on careful investigation of BP, with particular attention given to the differential diagnosis of BP, can improve the patient's function and esthetics.

The peroxidal oxidation of the lipids state was studied up, as well as of the whole blood neutrophils functional activity, hemodynamics and microcirculation of lower extremities in surgical treatment of the abdominal aorta aneurysm. The main significance in the reperfusional syndrome pathophysiology, caused by temporary overcompression of aorta, has the neutrophils activation, their interrelationship with the endothelium cells and the activity lowering of the tissue antioxidant system, manifestated by vascular spasm, which is mostly expressed in the patients with stenotic affection of the lower extremities arteries. Positive effect was noted in application of preparation corvitin, which has antioxidant action.

The achievement of a normal-appearing face after surgical resurfacing remains an elusive goal. This is due in part to insufficient color matching, restoration of contours, and the persistence of visible scars. Flap prefabrication is a staged procedure that provides an independent axial blood supply to local expanded tissues. We describe a new reconstructive alternative with superior reconstructive surgical options for facial resurfacing that better matches damaged or discarded facial tissues. A superficial temporal fascial flap was harvested as the vascular supply of the prefabricated neck flap and located in a subcutaneous neck pocket over a tissue expander. After a 5-month period for expansion and maturation, the prefabricated skin flap was raised, islanded, and rotated to resurface the facial defect. Four patients with hemifacial postburn contracture and two patients affected by hemifacial vascular malformations aged 17 to 42 years (mean 29 years) were successfully treated with no major complication after a mean period of 15 months. Prefabricated neck-expanded skin flap demonstrated an excellent color and texture match with facial skin that surrounded the repair sites, and optimal aesthetic results were obtained. Importantly, facial expression was completely maintained due to thinness and pliability of the rotated skin. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Abstract Objective To investigate a new approach to calculating cause-related standardized mortality rates that involves assigning weights to each cause of death reported on death certificates. Methods We derived cause-related standardized mortality rates from death certificate data for France in 2010 using: (i) the classic method, which considered only the underlying cause of death; and (ii) three novel multiple-cause-of-death weighting methods, which assigned weights to multiple causes of death mentioned on death certificates: the first two multiple-cause-of-death methods assigned non-zero weights to all causes mentioned and the third assigned non-zero weights to only the underlying cause and other contributing causes that were not part of the main morbid process. As the sum of the weights for each death certificate was 1, each death had an equal influence on mortality estimates and the total number of deaths was unchanged. Mortality rates derived using the different methods were compared. Findings On average, 3.4 causes per death were listed on each certificate. The standardized mortality rate calculated using the third multiple-cause-of-death weighting method was more than 20% higher than that calculated using the classic method for five disease categories: skin diseases, mental disorders, endocrine and nutritional diseases, blood diseases and genitourinary diseases. Moreover, this method highlighted the mortality burden associated with certain diseases in specific age groups. Conclusion A multiple-cause-of-death weighting approach to calculating cause-related standardized mortality rates from death certificate data identified conditions that contributed more to mortality than indicated by the classic method. This new approach holds promise for identifying underrecognized contributors to mortality. PMID:27994280

Single-fraction Radiosurgery for Presumed Intracranial Meningiomas: Efficacy and Complications From a 22-Year Experience

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pollock, Bruce E., E-mail: pollock.bruce@mayo.edu; Department of Radiation Oncology, Mayo Clinic College of Medicine, Rochester, MN; Stafford, Scott L.

Purpose: To define the rate of tumor control and factors associated with radiation-related complications after single-fraction radiosurgery (SRS) for patients with imaging defined intracranial meningiomas. Materials and Methods: Retrospective review of 251 patients (192 women, 59 men) having SRS for imaging-defined intracranial meningiomas between 1990 and 2008. Excluded were patients with radiation-induced tumors, meningiomatosis, or neurofibromatosis. The mean patient age was 58.6 {+-} 13.4 years. The majority of tumors involved the skull base/tentorium (n = 210, 83.7%). The mean treatment volume was 7.7 {+-} 6.2 cm{sup 3}; the mean tumor margin dose was 15.8 {+-} 2.0 Gy. Follow-up (mean, 62.9more » {+-} 43.9 months) was censored at last evaluation (n = 224), death (n = 22), or tumor resection (n = 5). Results: No patient died from tumor progression or radiation-related complications. Tumor size decreased in 181 patients (72.1%) and was unchanged in 67 patients (26.7%). Three patients (1.2%) had in-field tumor progression noted at 28, 145, and 150 months, respectively. No patient had a marginal tumor progression. The 3- and 10-year local control rate was 99.4%. One patient had distant tumor progression at 105 months and underwent repeat SRS. Thirty-one patients (12.4%) had either temporary (n = 8, 3.2%) or permanent (n = 23, 9.2%) symptomatic radiation-related complications including cranial nerve deficits (n = 14), headaches (n = 5), hemiparesis (n = 5), new/worsened seizure (n = 4), cyst-formation (n = 1), hemifacial spasm (n = 1), and stroke (n = 1). The 1- and 5-year complication rates were 8.3% and 11.5%, respectively. Radiation-related complications were associated with convexity/falx tumors (HR = 2.8, 95% CI 1.3-6.1, p = 0.009) and increasing tumor volume (HR = 1.05, 95% CI 1.0-1.1, p = 0.04) on multivariate analysis. No patient developed a radiation-induced tumor. Conclusions: Single-fraction SRS at the used dose range provides a high rate of tumor

1. The ability of several potassium (K+) channel openers to inhibit spasm of the uterus of the nonpregnant rat and their susceptibility to antagonism by glibenclamide was assessed in vitro and in vivo. 2. In the isolated uterus exposed to oxytocin (0.2 nM), cromakalim, RP 49356 and pinacidil were of similar potency (mean pD2 = 6.4, 6.0 and 6.2 respectively) while minoxidil sulphate was of lower potency (pD2 = 4.7). Glibenclamide antagonized cromakalim and RP 49356 with the interactions consistent with competitive antagonism (mean pA2 of 6.57 and 7.00 respectively). Glibenclamide also antagonized pinacidil (pA2 = 6.22) but the slope of the Schild plot was significantly greater than -1. Neither salbutamol nor minoxidil sulphate was antagonized by glibenclamide (10 microM). 3. Cromakalim (1 and 10 microM), RP 49356 (1 and 10 microM), pinacidil (1 microM) and minoxidil sulphate (100 microM) suppressed spasm evoked by low (less than 40 mM) but not high (greater than or equal to 40 mM) KCl concentrations. Glibenclamide (10 microM) prevented cromakalim (10 microM)-, RP 49356 (10 microM)- and pinacidil (10 microM)-induced suppression of KCl (20 mM)-evoked spasm. Pinacidil (10 and 100 microM), cromakalim (100 microM) and salbutamol (0.01-1 microM) inhibited spasm evoked by all concentrations of KCl (10-80 mM). Suppression of spasm evoked by KCl (10-80 mM) by cromakalim (100 microM) and pinacidil (100 microM) was insensitive to glibenclamide (10 microM). 4. Cromakalim (0.1 mg kg-1) and RP 49356 (0.1 mg kg-1), given by i.v. bolus injection, inhibited uterine contractions, produced a fall in blood pressure and a slight tachycardia in the conscious ovariectomized rat.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2128195

Tuberous sclerosis complex: correlation of magnetic resonance imaging (MRI) findings with comorbidities.

We studied the magnetic resonance imaging (MRI) findings in a cohort of Chinese children with tuberous sclerosis complex to determine the relationship between age, sex, mental retardation, autism, epilepsy, infantile spasm, and early age at onset of seizures and the numbers and locations of tubers detected. We searched our tuberous sclerosis registry, established in 1985 (N = 44), and performed an analysis of children who had MRIs of the brain performed (n = 22). A neuroradiologist blinded to the clinical findings scored the MRIs according to the total number and site of the tubers. The following factors were analyzed: age, sex, presence of autism (n = 7), presence (n = 19) and severity of mental retardation (mild [n = 12], moderate to severe [n = 7]), presence of epilepsy (n = 21) or infantile spasm (n = 8), and age at onset of seizures less than 1 year (n = 10). There was no significant relationship between the number and site of tubers and the following factors: sex, autism, mental retardation, degree of mental retardation, epilepsy, history of infantile spasm, or age at onset of seizures less than 1 year. Only the presence of cortical tubers in the parietal regions had a significant relationship with the history of infantile spasm (P = .012). Using multiple regression analysis of all of the risk factors, only age is related to the number of tubers in the MRI (P = .047), and a history of infantile spasm is related to the presence of tubers in the parietal (P = .009) and occipital (P = .031) lobes. The associated comorbidities in tuberous sclerosis complex might be explained by more complex underlying genetic or pathologic issues rather than purely by the site of the cortical tubers. We suggest that a developmental approach, by analyzing the age at the appearance of tubers in both symptomatic and asymptomatic cases with the development of other neuropsychiatric comorbidities, should be undertaken to assess the causal relationship.

Intracoronary Acetylcholine Provocation Testing for Assessment of Coronary Vasomotor Disorders.

Ong, Peter; Athanasiadis, Anastasios; Sechtem, Udo

2016-08-18

Intracoronary acetylcholine provocation testing (ACH-test) is an established method for assessment of epicardial coronary artery spasm in the catheterization laboratory which was introduced more than 30 years ago. Due to the short half-life of acetylcholine it can only be applied directly into the coronary arteries. Several studies have demonstrated the safety and clinical usefulness of this test. However, acetylcholine testing is only rarely applied in the U.S. or Europe. Nevertheless, it has been shown that 62% of Caucasian patients with stable angina and unobstructed coronary arteries on coronary angiography suffer from coronary vasomotor disorders that can be diagnosed with acetylcholine testing. In recent years it has been appreciated that the ACH-test not only assesses the presence of epicardial spasm but that it can also be useful for the detection of coronary microvascular spam. In such cases no epicardial spasm is seen after injection of acetylcholine but ischemic ECG shifts are present together with a reproduction of the patient's symptoms during the test. This article describes the experience with the ACH-test and its implementation in daily clinical routine.

Symptomatic spondylolysis resulting from a stress fracture of the pars interarticularis is a cause of low back pain in the juvenile and adolescent patient. Treatment is conservative in the majority of cases. To analyze the outcome of patients with symptomatic isthmic spondylolysis treated nonoperatively with a custom fit thoracolumbar orthosis and activity cessation for 3 months followed by an organized physical therapy program. Retrospective case series. Four hundred thirty-six juvenile and adolescent patients with spondylolysis. Pain improvement, hamstring flexibility, range of motion, resolution of back spasms, and return to previous activities. Retrospective review of 436 juvenile and adolescent patients with symptomatic spondylolysis confirmed by single-photon emission computed tomography or computed tomography. Clinical outcomes were assessed through patient history and physical examination. Ninety-five percent of patients achieved excellent results according to a modified Odom's Criteria. The remaining 5% of patients achieved good results as they required occasional nonsteroidal anti-inflammatory drugs to relieve pain. Back spasms were resolved and hamstring tightness and range of motion returned to normal in all patients. All patients returned to their preinjury activity level. No patients went on to surgery. Symptomatic juvenile and adolescent patients with an isthmus spondylolysis may be effectively managed with a custom fit thoracolumbar orthosis brace and activity cessation for approximately 3 months followed by an organized physical therapy program.

Traditional medicine scientists believed that sleeping under the stars and moonlight is not healthy because it brings about nose bleeds and respiratory problems. In Avicenna’s view, the spirit and its tendency to the light are introduced as main etiology, which cannot explain star light as a proper etiology. In modern knowledge, it seems cosmic rays that reach our planet’s atmosphere by electron cascade, play a key role. Internal organs’ electrical charge distribution disturbance caused by these electrons can lead to irregular spasms in the muscular walls of arteries and other organs. These interactions may finally lead to circulation (epistaxis and hypertension) and respiratory (catarrh) problems. PMID:29629052

Targeted Ultrasound-Guided Perineural Hydrodissection of the Sciatic Nerve for the Treatment of Piriformis Syndrome.

Piriformis syndrome is a common cause of lumbar, gluteal, and thigh pain, frequently associated with sciatic nerve symptoms. Potential etiologies include muscle injury or chronic muscle stretching associated with gait disturbances. There is a common pathological end pathway involving hypertrophy, spasm, contracture, inflammation, and scarring of the piriformis muscle, leading to impingement of the sciatic nerve. Ultrasound-guided piriformis injections are frequently used in the treatment of these pain syndromes, with most of the published literature describing injection of the muscle. We describe a safe, effective ultrasound-guided injection technique for the treatment of piriformis syndrome using targeted sciatic perineural hydrodissection followed by therapeutic corticosteroid injection.

Most companies make charitable donations, but few approach their contributions with an eye toward enhancing their brands. Those that do take such an approach commit talent and know-how, not just dollars, to a pressing but carefully chosen social need and then tell the world about the cause and their service to it. Through the association, both the business and the cause benefit in ways they could not otherwise. Organizations such as Avon, ConAgra Foods, and Chevrolet have recognized that a sustained cause-branding program can improve their reputations, boost their employees' morale, strengthen relations with business partners, and drive sales. And the targeted causes receive far more money than they could have from direct corporate gifts alone. The authors examine these best practices and offer four principles for building successful cause-branding programs. First, they say, a company should select a cause that advances its corporate goals. That is, unless the competitive logic for supporting the cause is clear, a company shouldn't even consider putting its finite resources behind it. Second, a business should commit to a cause before picking its charitable partners. Otherwise, a cause-branding program may become too dependent on its partners. Third, a company should put all its assets to work, especially its employees. It should leverage the professional skills of its workers as well as its other assets such as distribution networks. And fourth, a company should promote its philanthropic initiatives through every possible channel. In addition to using the media, it should communicate its efforts through the Web, annual reports, direct mail, and so on. Cause branding is a way to turn the obligations of corporate citizenship into a valuable asset. When the cause is well chosen, the commitment genuine, and the program well executed, the cause helps the company, and the company helps the cause.

Vitamin K has been associated with various health outcomes, including non-fatal cardiovascular diseases (CVD) and cancer. However, little is known about the association between vitamin K intake and all-cause and cause specific mortality. This study aims to investigate the association between vitamin K intake and all-cause and cause-specific mortality. This prospective cohort study included 33,289 participants from the EPIC-NL cohort, aged 20-70 years at baseline and recruited between 1993 and 1997. Dietary intake was assessed at baseline with a validated food frequency questionnaire and intakes of phylloquinone, and total, short chain and long chain menaquinones were calculated. Information on vital status and causes of death was obtained through linkage to several registries. The association between the different forms of vitamin K intake and mortality was assessed with Cox proportional hazards, adjusted for risk factors for chronic diseases and nutrient intake. During a mean follow-up of 16.8 years, 2863 deaths occurred, including 625 from CVD (256 from coronary heart disease (CHD)), 1346 from cancer and 892 from other causes. After multivariable adjustment, phylloquinone and menaquinones were not associated with all-cause mortality with hazard ratios for the upper vs. the lowest quartile of intake of 1.04 (0.92;1.17) and 0.94 (0.82;1.07) respectively. Neither phylloquinone intake nor menaquinone intake was associated with risk of CVD mortality. Higher intake of long chain menaquinones was borderline significantly associated (p trend  = 0.06) with lower CHD mortality with a HR 10μg of 0.86 (0.74;1.00). None of the forms of vitamin K intake were associated with cancer mortality or mortality from other causes. Vitamin K intake was not associated with all-cause mortality, cancer mortality and mortality from other causes. Copyright © 2016. Published by Elsevier Ltd.

Local injections of corticotropin releasing factor reduce doxorubicin-induced acute inflammation in the eyelid.

Doxorubicin chemomyectomy is an effective alternative treatment option for patients with blepharospasm and hemifacial spasm. One side effect of the use of doxorubicin in localized injections is the development of acute inflammation and skin injury at the injection site. Corticotropin releasing factor (CRF) was reported to reduce inflammation after acute inflammatory injuries due to other causes and at other sites. This study was performed to assess the potential of CRF to prevent the development of skin injury and eyelid soreness after local doxorubicin injection. Rabbits received lower eyelid injections of either 75 or 150 micrograms CRF followed by injection of either 0.5, 1, or 2 mg doxorubicin or doxorubicin alone. Eyelids were assessed for changes in acute inflammation by immunohistochemical localization of macrophages and monocytes using anti-CD11, an antibody specific for these cell types. Short-term alterations in vascular permeability were assessed using an Evans blue assay. Additional eyelids were followed daily for changes in the skin over the injection site to determine day of onset of skin injury and the total duration of skin injury. After 1 month, the eyelids were processed histologically for morphometric analysis of muscle fiber loss. Monkey eyelids also were examined for the effect of CRF and doxorubicin injections. Doxorubicin alone produced an acute inflammatory reaction in the treated eyelids, with a large influx of macrophages and monocytes throughout the connective tissue at 1 and 2 days. Corticotropin releasing factor pretreatment significantly reduced this influx of inflammatory cells into the connective tissue. Doxorubicin produced a large increase in vascular permeability in the treated eyelids, with resultant edema. Corticotropin releasing factor did not alter this change in vascular permeability, indicating that CRF appears to have a specific effect on migration of inflammatory cells rather than just a generalized effect on vascular

This study was conducted in order to determine the effect of an occlusal splint on craniocervical relationships, in subjects with muscle spasms in the sternocleidomastoid and trapezius muscles. A full-arch maxillary stabilization occlusal splint was made for each of the 15 subjects. Two lateral craniocervical radiographs were taken for each subject, with and without an occlusal splint. Cephalometric analysis showed that the splint caused a significant extension of the head on the cervical spine. There was also a significant decrease in the cervical spine lordosis in the first, second and third cervical segment. These cervical changes could be a compensation mechanism caused by the extension of the cranium on the upper cervical spine. The change in the curvature implies that it is necessary to periodically evaluate the changes occurring in the craniocervical relationships after the occlusal splint has been inserted.

This study explored the role of TCOF1 insertion mutations in Taiwanese patients with craniofacial anomalies. Twelve patients with single or multiple, asymmetrical congenital craniofacial anomalies were enrolled. Genomic DNA was prepared from leukocytes; the coding regions of TCOF1 were analyzed by polymerase chain reaction and direct sequencing. Clinical manifestations were correlated to the TCOF1 mutation. Six of 12 patients diagnosed with hemifacial microsomia exhibited a novel insertion mutation 4127 ins G (frameshift) in exon 24 in the TCOF1 gene. All six patients were diagnosed with anomalies on the left side. In addition, four of these six patients had hearing impairment; three had other major anomalies; and two had developmental delay. The insertion caused a frameshift, an early truncation, the loss of two putative nuclear localization signals (residues 1404-1420 and 1424-1440), and the loss of coiled coil domain (1406-1426) in treacle protein. These findings support the existence of two regulators of growth of the mandibular condyles. © 2011 John Wiley & Sons A/S.

Mechanisms underlying capsaicin effects in canine coronary artery: implications for coronary spasm

Aims The TRPV1, transient receptor potential vanilloid type 1, agonist capsaicin is considered to be beneficial for cardiovascular health because it dilates coronary arteries through an endothelial-dependent mechanism and may slow atheroma progression. However, recent reports indicate that high doses of capsaicin may constrict coronary arterioles and even provoke myocardial infarction. Thus far, the mechanisms by which TRPV1 activation modulates coronary vascular tone remain poorly understood. This investigation examined whether there is a synergistic interplay between locally acting vasoconstrictive pro-inflammatory hormones (autacoids) and capsaicin effects in the coronary circulation. Methods and results Experiments were performed in canine conduit coronary artery rings and isolated smooth muscle cells (CASMCs). Isometric tension measurements revealed that 1–10 μM capsaicin alone did not affect resting tension of coronary artery rings. In contrast, in endothelium-intact rings pre-contracted with a Gq/11-coupled FP/TP (prostaglandin F/thromboxane) receptor agonist, prostaglandin F2α (PGF2α; 10 μM), capsaicin first induced transient dilation that was followed by sustained contraction. In endothelium-denuded rings pre-contracted with PGF2α or thromboxane analogue U46619 (1 μM, a TP receptor agonist), capsaicin induced only sustained contraction. Blockers of the TP receptor or TRPV1 significantly inhibited capsaicin effects, but these were still observed in the presence of 50 μM nifedipine and 70 mM KCl. Capsaicin also potentiated 20 mM KCl-induced contractions. Fluorescence imaging experiments in CASMCs revealed that the Gq/11-phospholipase C (PLC)-protein kinase C (PKC) and Ca2+-PLC-PKC pathways are likely involved in sensitizing CASMC TRPV1 channels. Conclusion Capsaicin alone does not cause contractions in conduit canine coronary artery; however, pre-treatment with pro-inflammatory prostaglandin–thromboxane agonists may unmask capsaicin

Spasticity is a common post-stroke complication, and it results in substantial deterioration in the quality of life of patients. Although potential positive effects of warm-needle moxibustion on spasticity after stroke have been observed, evidence on its definitive effect remains uncertain. This study aimed to summarize clinical evidence pertaining to therapeutic effects and safety of warm-needle moxibustion for treating spasticity after stroke. Randomized controlled trials were reviewed systematically on the basis of the Cochrane Handbook for Systematic Reviews of Interventions. The report follows the PRISMA statement. Ten electronic databases (PubMed, CENTRAL, EMBASE, AMED, CINAHL, Web of Science, CBM, CNKI, WanFang, and VIP) were explored, and articles were retrieved manually from two Chinese journals (The Journal of Traditional Chinese Medicine and Zhong Guo Zhen Jiu) through retrospective search. Randomized controlled trials with warm-needle moxibustion as treatment intervention for patients with limb spasm after stroke were included in this review. The risk of bias assessment tool was utilized in accordance with Cochrane Handbook 5.1.0. All included studies reported spasm effect as primary outcome. Effect size was estimated using relative risk, standardized mean difference, or mean difference with a corresponding 95% confidence interval. Review Manager 5.3 was utilized for meta-analysis. Twelve randomized controlled trials with certain methodological flaws and risk of bias were included, and they involved a total of 878 participants. Warm-needle moxibustion was found to be superior to electroacupuncture or acupuncture in reducing spasm and in promoting motor function and daily living activities. Pooled results for spasm effect and motor function were significant when warm-needle moxibustion was compared with electroacupuncture or acupuncture. A comparison of daily living activities indicated significant differences between warm-needle moxibustion and

The histology of coronary arteries was compared in patients with rest and effort angina. The arteries came from six patients with three vessel disease who died within four weeks of arteriography and ambulatory ST segment monitoring. Sections of all macroscopically visible arteries were taken every 5 mm and examined histologically. Episodes of ST segment depression had occurred on exertion in two patients, during exertion and rest (nocturnal) in two, and two patients had had no episodes of ST segment depression during ambulatory monitoring. Concentric (29%) or eccentric (62%) intimal thickening due to atheroma or fibroelastic tissue was found in 91% of sections. All but two normal intimal sections (1%) were found to be diseased in patients with ambulatory ST segment changes. Eccentric lesions with medial smooth muscle preservation in areas without intimal thickening, where further luminal narrowing could occur due to increases in smooth muscle tone, were found in 15% of sections. But these areas were not found in the proximal 3.5 cm of any of the major coronary arteries of the two patients with rest and effort ischaemia. Spasm could not have caused total occlusion in any of these arteries because the lumen was splinted by the lesion. There was no difference in mean luminal narrowing between patients with exertional and rest ischaemia and exertional ischaemia only (mean 74%), but mean luminal narrowing was lower in patients with no ambulatory episodes of ST segment change (39%). Thus medial smooth muscle spasm was unlikely to have caused occlusion in patients with ambulatory ST segment changes, although it could have altered lumen diameter. There are no histological differences in the coronary arteries of patients with rest or effort induced myocardial ischaemia. Images PMID:4052277

Myokymia is one of the involuntary movements, which is characterized by undulatory muscle spasm, similar to the worm's crawl. Sometimes muscle pain, itchy sensation, dysautonomia and other symptoms are associated with it. Cases showing normal neurological findings are rare. Myokymia is caused by various diseases, such as, multiple sclerosis, hypothyroidism, Guillan-Barre syndrome and so on. Generally myokymia is classified into two types, i.e. limb myokymia and facial myokymia according to the site. On the other hand, myokymia with hyperhidrosis is known as Issacs syndrome. There are many opinions about the pathogenesis and mechanism in the myoneural junction, peripheral nerve or spinal cord, however these are not established. Further investigation of myokymia is expected.

Epilepsy is a common nervous system disease often related to consciousness disturbances and muscular spasm which affects about 1% of the human population. Despite major technological advances done in medicine in the last years there was no sufficient progress towards overcoming it. Application of advanced statistical methods and computer image analysis offers the hope for accurate detection and later removal of an epileptiform focuses which are the cause of some types of epilepsy. The aim of this work was to create a computer system that would help to find and diagnose disorders of blood circulation in the brain This may be helpful for the diagnosis of the epileptic seizures onset in the brain.

A case of proctalgia fugax.

Higgins, G L

1984-05-01

The syndrome called proctalgia fugax may be a repository of various conditions, because there are no distinctive signs or supporting tests. Usually, the pain of this condition is described as cramping, gnawing or tight, and lasts about ten to 15 minutes. It occurs most frequently at night and is localized to the rectal region above the anus. One subgroup may be diagnosed by the existence of a `shelf sign' in the rectum. This shelf is probably caused by pubococcygeus spasm. Patients suffering from proctalgia fugax tend to be perfectionists and above average in intelligence. A literature review and the case history of one patient illustrate the difficulties, frustrations and pitfalls associated with this incurable condition.

[Purpose] This study prescribed pain-free range exercises for a female amateur skier who complained of limitations in her shoulder range of motion, and pain caused by protective spasms; the tester evaluated the effects of such exercise on pain. [Subject and Methods] A 23-year-old female who complained of pain of 3 weeks in duration in the right glenohumoral and scapulothoracic joints was enrolled. [Results] After pain-free range exercises, the visual analog pain score was 2 and the shoulder flexion and abduction angles improved compared to the initial values. [Conclusion] Thus, this study suggests muscle-strengthening exercises within the pain-free range, rather than simple pain treatments, as therapy for acute muscle injuries in skiers.

The normal sagittal alignment of the cervical spine is lordotic and is affected by the posture of the head and neck. The question of whether loss of cervical lordosis is the result of muscle spasm after injury or a normal variation, and the clinical significance of such changes in sagittal profile of the cervical spine has been an issue of several studies. The purpose of this paper is to study the incidence of normal cervical lordosis and its changes after neck injury compared to the healthy population. We studied the lateral radiographs of the cervical spine of 60 patients with neck injury compared to 100 patients without a neck injury. Lateral radiographs were obtained in the standing or sitting position, and the curvature of the cervical spine was measured using the angle formed between the inferior end plates of the C2 and C7 vertebrae. In the patients without neck injury, lordotic and straight cervical spine sagittal alignment was observed in 36.5% each, double curvature in 17%, and kyphotic in 10%. In the patients with neck injury, lordotic sagittal alignment was observed in 36%, straight in 34%, double curvature in 26% and kyphotic in 4%. No significant difference between the two groups regarding all types of sagittal alignment of the cervical spine was found (p > 0.100). The alterations in normal cervical lordosis in patients with neck injury must be considered coincidental. These alterations should not be associated with muscle spasm caused by neck pain.

Pseudoinfarction pattern in a patient with hyperkalemia, diabetic ketoacidosis and normal coronary vessels: a case report.

PubMed

Ziakas, Antonios; Basagiannis, Christos; Stiliadis, Ioannis

2010-04-26

A rare electrocardiographic finding of hyperkalemia is ST segment elevation or the so called 'pseudoinfarction' pattern. It has been suggested that hyperkalemia causes the 'pseudoinfarction' pattern not only through its direct myocardial effects, but also through other mechanisms, such as anoxia, acidosis, and coronary artery spasm. A 33-year-old Caucasian woman with insulin-treated diabetes presented with continuous epigastric pain of four hours duration. Her coronary heart disease risk factors apart from diabetes included hypercholesterolemia and smoking. Her initial electrocardiogram revealed ST segment elevation in the anteroseptal leads consistent with anterior myocardial infarction. Blood tests revealed hyperglycemia, hyperkalemia, metabolic acidosis and urine ketones, while a bed-side cardiac echocardiogram showed no segmental wall motion abnormality. We provisionally diagnosed diabetic ketoacidosis that was possibly precipitated by acute myocardial infarction, as there were findings in favor of (epigastric pain, electrocardiogram pattern, presence of 3 coronary heart disease risk factors) and against (young age, normal echocardiogram) the diagnosis of acute myocardial infarction. We performed cardiac angiography in order to exclude an anterior acute myocardial infarction, which could lead to myocardial damage and possible severe complications should there be a delay in treatment. Angiography revealed normal coronary arteries. During the procedure, ST segment elevation in the anteroseptal leads was still present in our patient's electrocardiogram results. ST segment elevation is a rare manifestation of hyperkalemia. In our patient, coronary spasm did not contribute to such an electrocardiography finding.

Are coronary artery spasm and progressive damage to the heart associated with the hyperventilation syndrome?

PubMed Central

Freeman, L J; Nixon, P G

1985-01-01

A case of coronary artery vasospasm was studied in a man with a four year history of angina. He had evidence of symptomatic hyperventilation during a spontaneous episode of chest pain. When asked to hyperventilate the pain in his chest and ST elevation were reproduced in the same leads as occurred during the spontaneous attack. This may be the first reported case of spontaneous hyperventilation producing vasoconstriction, and the patient's previous admissions to the coronary care unit may have been associated with coronary vasospasm induced by hyperventilation. When patients with variant angina report pains in the chest in association with dizziness and breathlessness hyperventilation should be considered to be a possible cause of the symptoms. As coronary vasospasm is increasingly implicated in angina after myocardial infarction the role of hyperventilation should be considered more often. PMID:3931741

Tuberculous otitis media can provide a diagnostic challenge even to the most astute and experienced clinician. The rarity of the condition and its propensity to masquerade as commoner otological conditions further delays diagnosis and treatment. We present the case of a 22-year-old female who presented with chronic aural discharge, unilateral hearing loss and recurrent hemifacial paralysis. The paper highlights the difficulty in diagnosis and stresses the need for a high index of suspicion in cases resistant to the common methods of treatment.

[Cause of death: from primary disease to direct cause of death].

Oppewal, F; Smedts, F M M; Meyboom-de Jong, B

2005-07-23

Following the death of a patient, the treating physician in the Netherlands is required to fill out two forms. Form A, which is the certificate of death and Form B, which is used by the Statistics Netherlands to compile data on causes ofdeath. The latter form often poses difficulty for the physician with respect to the primary cause of death. This applies particularly to cases of sudden death, which account for one third of all deaths in the Netherlands. As a result, the statistical analyses appear to lead to an incorrect representation of the distribution of causes of death. A more thorough investigation into the primary cause of death is desirable, if necessary, supported by a request for an autopsy. The primary cause of death is to be regarded as the basic disease from which the cascade of changes ultimately leading to death originated.

Mutations in the human X-linked cyclin-dependent kinase-like 5 (CDKL5) gene have been shown to cause infantile spasms as well as Rett syndrome (RTT)-like phenotype. To date, less than 25 different mutations have been reported. So far, there are still little data on the key clinical diagnosis criteria and on the natural history of CDKL5-associated encephalopathy. We screened the entire coding region of CDKL5 for mutations in 183 females with encephalopathy with early seizures by denaturing high liquid performance chromatography and direct sequencing, and we identified in 20 unrelated girls, 18 different mutations including 7 novel mutations. These mutations were identified in eight patients with encephalopathy with RTT-like features, five with infantile spasms and seven with encephalopathy with refractory epilepsy. Early epilepsy with normal interictal EEG and severe hypotonia are the key clinical features in identifying patients likely to have CDKL5 mutations. Our study also indicates that these patients clearly exhibit some RTT features such as deceleration of head growth, stereotypies and hand apraxia and that these RTT features become more evident in older and ambulatory patients. However, some RTT signs are clearly absent such as the so called RTT disease profile (period of nearly normal development followed by regression with loss of acquired fine finger skill in early childhood and characteristic intensive eye communication) and the characteristic evolution of the RTT electroencephalogram. Interestingly, in addition to the overall stereotypical symptomatology (age of onset and evolution of the disease) resulting from CDKL5 mutations, atypical forms of CDKL5-related conditions have also been observed. Our data suggest that phenotypic heterogeneity does not correlate with the nature or the position of the mutations or with the pattern of X-chromosome inactivation, but most probably with the functional transcriptional and/or translational consequences of CDKL5

Cannabis may alleviate some symptoms associated with multiple sclerosis (MS). This study investigated the effect of an orally administered standardized Cannabis sativa plant extract in MS patients with poorly controlled spasticity. During their inpatient rehabilitation programme, 57 patients were enrolled in a prospective, randomized, double-blind, placebo-controlled crossover study of cannabis-extract capsules standardized to 2.5 mg tetrahydrocannabinol (THC) and 0.9 mg cannabidiol (CBD) each. Patients in group A started with a drug escalation phase from 15 to maximally 30 mg THC by 5 mg per day if well tolerated, being on active medication for 14 days before starting placebo. Patients in group B started with placebo for seven days, crossed to the active period (14 days) and closed with a three-day placebo period (active drug dose escalation and placebo sham escalation as in group A). Measures used included daily self-report of spasm frequency and symptoms, Ashworth Scale, Rivermead Mobility Index, 10-m timed walk, nine-hole peg test, paced auditory serial addition test (PASAT), and the digit span test. In the 50 patients included into the intention-to-treat analysis set, there were no statistically significant differences associated with active treatment compared to placebo, but trends in favour of active treatment were seen for spasm frequency, mobility and getting to sleep. In the 37 patients (per-protocol set) who received at least 90% of their prescribed dose, improvements in spasm frequency (P = 0.013) and mobility after excluding a patient who fell and stopped walking were seen (P = 0.01). Minor adverse events were slightly more frequent and severe during active treatment, and toxicity symptoms, which were generally mild, were more pronounced in the active phase. A standardized Cannabis sativa plant extract might lower spasm frequency and increase mobility with tolerable side effects in MS patients with persistent spasticity not responding to other drugs.

This prospective study assesses balloon-assisted tracking (BAT) in reducing radial access failure during percutaneous coronary intervention (PCI). Arterial spasm prevents PCI from the radial artery in a small percentage of cases. A total of 2223 consecutive patients undergoing PCI from the radial approach were analyzed. Radial access failure mode and requirement for crossover to femoral access during a 12-month run-in period were compared with the following 14-month period with routine BAT usage. During the 14-month study period, 1334 radial PCIs were attempted. Twenty-six patients switched to femoral at an early stage, while 76 encountered radial spasm and underwent successful BAT in 69 cases (91%), giving a total crossover rate to femoral of 33/1334 (2.5%). Utilizing BAT rather than a femoral puncture reduced our institution's radial-femoral crossover rate from 7.6% to 2.5% (P<.01), which is also significantly lower than the radial-femoral crossover rate in the 12 months before BAT implementation (6.1%; P<.01). Mean procedure times were similar for those requiring BAT compared with conventional radial access (51.3 ± 21.3 min vs 47.9 ± 23.7 min; P=.23), and those crossing straight to femoral (BAT not attempted) (60.7 ± 31.9 min; P=.10). Mean first device/balloon time for the BAT-assisted primary PCI cases (22.6 ± 9.4 min) was similar to cases that had radial difficulties and converted to femoral without attempting BAT (25.8 ± 13.4 min; P=.54). BAT allowed catheter passage despite radial spasm in 91% of cases, significantly reducing the institution's rate of femoral crossover. During radial spasm in primary PCI, using BAT did not delay reperfusion compared with femoral crossover.

Background. Multiple sclerosis (MS) is a chronic demyelinating neurological disease. Several studies have reported that complementary and alternative therapies can have positive effects against pain in these patients. Objective. The objective was to investigate the effectiveness of an Ai-Chi aquatic exercise program against pain and other symptoms in MS patients. Methods. In this randomized controlled trial, 73 MS patients were randomly assigned to an experimental or control group for a 20-week treatment program. The experimental group underwent 40 sessions of Ai-Chi exercise in swimming pool and the control group 40 sessions of abdominal breathing and contraction-relaxation exercises in therapy room. Outcome variables were pain, disability, spasm, depression, fatigue, and autonomy, which were assessed before the intervention and immediately and at 4 and 10 weeks after the last treatment session. Results. The experimental group showed a significant (P < 0.028) and clinically relevant decrease in pain intensity versus baseline, with an immediate posttreatment reduction in median visual analogue scale scores of 50% that was maintained for up to 10 weeks. Significant improvements were also observed in spasm, fatigue, disability, and autonomy. Conclusion. According to these findings, an Ai-Chi aquatic exercise program improves pain, spasms, disability, fatigue, depression, and autonomy in MS patients.

We present an overview of the tactics we have used to achieve a high-level of performance while improving portability for a large-scale molecular dynamics code SPaSM. SPaSM was originally implemented in ANSI C with message passing for the Connection Machine 5 (CM-5). In 1993, SPaSM was selected as one of the winners in the IEEE Gordon Bell Prize competition for sustaining 50 Gflops on the 1024 node CM-5 at Los Alamos National Laboratory. Achieving this performance on the CM-5 required rewriting critical sections of code in CDPEAC assembler language. In addition, the code made extensive use of CM-5 parallel I/Omore » and the CMMD message passing library. Given this highly specialized implementation, we describe how we have ported the code to the Cray T3D and high performance workstations. In addition we will describe how it has been possible to do this using a single version of source code that runs on all three platforms without sacrificing any performance. Sound too good to be true? We hope to demonstrate that one can realize both code performance and portability without relying on the latest and greatest prepackaged tool or parallelizing compiler.« less

Abstract Traumatic brain injury (TBI) is an alteration in brain function, caused by an external force, which may be a hit on the skull, rapid acceleration or deceleration, penetration of an object, or shock waves from an explosion. Traumatic brain injury is a major cause of morbidity and mortality worldwide, with a high prevalence rate in pediatric patients, in which treatment options are still limited, not available at present neuroprotective drugs. Although the therapeutic management of these patients is varied and dependent on the severity of the injury, general techniques of drug types are handled, as well as physical and surgical. Baclofen is a muscle relaxant used to treat spasticity and improve mobility in patients with spinal cord injuries, relieving pain and muscle stiffness. Pharmacological support with baclofen is contradictory, because disruption of its oral administration may cause increased muscle tone syndrome and muscle spasm, prolonged seizures, hyperthermia, dysesthesia, hallucinations, or even multisystem organ failure. Combined treatments must consider the pathophysiology of broader alterations than only excitation/inhibition context, allowing the patient's reintegration with the greatest functionality.

Environmental Causes of Asthma.

PubMed

Cockcroft, Donald W

2018-02-01

Environmental factors which cause asthma are those that induce airway inflammation with eosinophils (more common) or neutrophils along with airway hyperresponsiveness (AHR). The most common of these (indeed the most common cause of asthma) are IgE-mediated inhalant allergen exposures. Allergen-induced AHR and inflammation are both associated with the allergen-induced late asthmatic response (LAR). Although allergens were previously recognized only as causes of symptoms and bronchoconstriction in asthmatics, we now appreciate them as causes of the fundamental pathophysiologic features of asthma. Low-molecular-weight chemical sensitizers, causes of occupational asthma, also cause asthma in a manner analogous to allergen. Acute irritant-induced asthma (reactive airways dysfunction syndrome) following a very heavy irritant exposure and chronic irritant-induced asthma following repeated high exposures can also induce persistent or permanent changes (inflammation and AHR) consistent with asthma. Textile dust exposure produces a different form of airway disease (byssinosis) which is less frequently observed currently. Environmental exposure to tobacco smoke facilitates the development of asthma in children. Personal smoking and environmental air pollution have an inconsistent and likely generally small effect in causing asthma. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

[Tetanus and Clostridium tetani--a brief review].

PubMed

Stock, Ingo

2015-02-01

Tetanus is an acute, often fatal, disease caused by an exotoxin (tetanospasmin) produced by the anaerobic, gram-positive spore-forming bacterium Clostridium tetani. It is characterized by generalized rigidity and convulsive spasms of skeletal muscles. In most industrialized countries, tetanus is a rare disease. However, in many tropical and subtropical countries with low vaccination coverage and poor medical care, it is still widely distributed. This applies in particular for neonatal tetanus. About 50 000 newborns and infants die each year from consequences from this severe illness. Management of tetanus involves neutralization of free circulating toxin, adequate antibacterial and symptomatic therapy as well as intensive care of the patient. For prophylaxis of the disease, active tetanus toxoid vaccination is the method of choice.

High-resolution manometry (HRM) has been applied to assess esophageal motility disorders. However, the frequency and types of motility disorders in patients with dysphagia, which are frequently seen in clinical practice, are not clear. We evaluated latent esophageal motility disorders associated with dysphagia. The study included patients without erosive esophageal mucosal damage and with dysphagia symptoms refractory to at least 8 weeks of standard-dose proton pump inhibitors. After enrolment, HRM was used to evaluate for esophageal motility disorder based on the Chicago classification. Esophageal motility disorder was found in 58 of 100 patients and was classified based on the causes: achalasia (13%), esophagogastric junction outflow obstruction (16%), distal esophageal spasms (3%), weak peristalsis (14%), frequently failed peristalsis (5%), and hypertensive peristalsis (7%). Primary esophageal motility disorder was found in approximately 50% of cases in dysphagia patients. Therefore, esophageal motility disorder is not an uncommon condition and should be sought for in order to elucidate precisely the cause of dysphagia. © 2017 S. Karger AG, Basel.

X-ray analysis of aerosol samples from a therapeutic cave

Cave therapy is an efficient therapeutic method to cure asthma, the exact healing effect, however, is not clarified, yet. This study is motivated by the basic assumption that aerosols do play the key role in the cave therapy. This study is based on measurements of single aerosol particles originating from a therapeutic cave of Budapest, Hungary (Szemlőhegyi cave). Aerosol particles have been collected in the regions arranged for the therapeutic treatment. Samples were further analysed for chemical and morphological aspects, determining the particle size distribution and classifying them according to elemental composition. Three particle classes have been detected based on major element concentration: alumino-silicate, quartz and calcium carbonate. Calcium ions have well-known physiological influence: anti-spastic, anti-inflammation and excretion reducing effects. Inflammation, accompanying spasm and extreme excretion production cause the smothering stigma, the so-called asthma. Therefore it could be assumed that calcium ions present in high concentration in the cave's atmosphere is the major cause of the healing effect.

Tetanus can occur after an injury and is caused by the exotoxin of Clostridium tetani. Characteristics of generalised tetanus include spasms in the back and other muscles, trismus, risus sardonicus and difficulty in breathing caused by laryngospasms. Vaccination through the National Vaccination Programme of the Netherlands has resulted in 94% of the population being protected against tetanus; certain groups, however, have a low rate of vaccination. In the Netherlands, 5 patients were reported to have generalised tetanus in 2011. This figure is relatively high in comparison with previous years. Of these 5 patients, 3 did not receive post-exposure-prophylaxis (PEP) after their injuries, or received it incompletely. PEP may be comprised of 1 or more vaccinations with the tetanus toxoid and/or the administration of tetanus immunoglobulin. Patients who have sustained an injury should be evaluated in accordance with the guideline 'Tetanus' by the Landelijke Coördinatie Infectieziekten (National Coordination Centre for communicable disease control), and to assess whether PEP is indicated.

In developing countries, investigating mortality levels and causes of death among all age female population despite the childhood and maternal related deaths is important to design appropriate and tailored interventions and to improve survival of female residents. Under Kilite-Awlealo Health and Demographic Surveillance System, we investigated mortality rates and causes of death in a cohort of female population from 1st of January 2010 to 31st of December 2012. At the baseline, 33,688 females were involved for the prospective follow-up study. Households under the study were updated every six months by fulltime surveillance data collectors to identify vital events, including deaths. Verbal Autopsy (VA) data were collected by separate trained data collectors for all identified deaths in the surveillance site. Trained physicians assigned underlining causes of death using the 10th edition of International Classification of Diseases (ICD). We assessed overall, age- and cause-specific mortality rates per 1000 person-years. Causes of death among all deceased females and by age groups were ranked based on cause specific mortality rates. Analysis was performed using Stata Version 11.1. During the follow-up period, 105,793.9 person-years of observation were generated, and 398 female deaths were recorded. This gave an overall mortality rate of 3.76 (95% confidence interval (CI): 3.41, 4.15) per 1,000 person-years. The top three broad causes of death were infectious and parasitic diseases (1.40 deaths per 1000 person-years), non-communicable diseases (0.98 deaths per 1000 person-years) and external causes (0.36 per 1000 person-years). Most deaths among reproductive age female were caused by Human Deficiency Virus/Acquired Immune Deficiency Virus (HIV/AIDS) and tuberculosis (0.14 per 1000 person-years for each cause). Pregnancy and childbirth related causes were responsible for few deaths among women of reproductive age--3 out of 73 deaths (4.1%) or 5.34 deaths per 1,000 person

Achieving aesthetic results in facial reconstructive microsurgery: planning and executing secondary refinements.

PubMed

Haddock, Nicholas T; Saadeh, Pierre B; Siebert, John W

2012-12-01

Free tissue transfer to improve bulk and contour in facial deformities has been proven useful, yet refinements that turn an acceptable result into an excellent result are essential to reconstruction. The authors reviewed their experience and described these refinements. The charts of 371 free tissue transfer cases (1989 to 2010) performed by the senior author (J.W.S.) were reviewed. Free tissue transfer of a circumflex scapular variant flap or superficial inferior epigastric was performed to treat deformities arising from hemifacial atrophy (n = 126), hemifacial microsomia (n = 89), radiation therapy (n = 40), bilateral malformations including lupus and polymyositis (n = 50), other congenital anomalies (n = 25), facial palsy (n = 17), and burns and trauma (n = 24). Revision surgery planning began at initial flap operation where the flap was stretched maximally and interdigitated with recipient tissue. More tissue was required in the malar region. Revision refinement was indicated in all cases (after 6 months). Flap revision involved liposuction, debulking, reelevation, and release of tethering, followed by tissue rearrangement by means of advancement, rotation, transposition, and/or turnover flaps of subcutaneous tissues from the previous free flap. The jawline frequently required more debulking. Periorbital reconstruction was combined with lower lid support with or without canthal repositioning. Conventional face-lift techniques with the flap as superficial musculoaponeurotic system augmented the result. Autologous fat injection to the alar rim, medial canthus, upper eyelid, and lip was a useful adjunct. Severe lip deficiencies were addressed with local flaps. The keys to improving results were continual critical reassessment, open-mindedness to new approaches, and maintaining high expectations. Therapeutic, V.

FMLP provokes coronary vasoconstriction and myocardial ischemia in rabbits

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gillespie, M.N.; Booth, D.C.; Friedman, B.J.

Recent pathological studies of coronary arteries from humans with suspected coronary spasm have revealed an augmented intramural burden of inflammatory cells. To test the hypothesis than inappropriate activation of inflammatory cells participates in the evolution of coronary vasospasm, the present experiment employed a newly developed coronary arteriographic technique for use in pentobarbital-anesthetized rabbits to evaluate the coronary vasomotor actions of the nonselective inflammatory cell stimulant, N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMLP). In 10 of 10 animals, selective left intracoronary injection of 200 ng fMLP evoked profound left coronary narrowing accompanied in all cases by ST segment deviation and dysrhythmias. Thallium-201 scintigraphy demonstrated hypoperfusion ofmore » the left ventricular free wall and septum supplied by the spastic coronary artery. The fMLP-induced epicardial vasoconstriction, ischemic electrocardiogram (ECG) changes, and thallium perfusion defects were reversed by intravenous nitroglycerin. Neither the right coronary artery nor its distribution were influenced by left coronary injection of fMLP. Additional experiments in isolated, salt solution-perfused rabbit hearts demonstrated that fMLP failed to exert direct coronary vasoconstrictor effects. These observations indicate that the nonselective inflammatory cell stimulant, fMLP, provokes arteriographically demonstrable coronary spasm with attendant myocardial hypoperfusion and ischemic ECG changes in anesthetized rabbits. Such a model may be useful in exploring the dynamic role of inflammatory cells in development of coronary spasm.« less

To provide information and comparison pertaining to visual impairment of Maori children with other children in New Zealand in particular: prevalence of blindness, causes of visual impairment, and avoidable causes of visual impairment. Retrospective data collection utilising the WHO/PBL eye examination record for children with blindness and low vision at Blind and Low Vision Education Network New Zealand (BLENNZ), Homai. Individuals not of Maori ethnicity or over the age of 16 were excluded from the study. 106 blind and 64 low-vision Maori children were studied. The main cause of blindness in Maori children is cortical visual impairment. Twenty-eight percent of causes of blindness in this population are potentially avoidable with non-accidental injury as the main cause. The prevalence of blindness and low vision in children amounts to 0.05% and 0.03%, respectively. The prevalence and causes of childhood blindness are comparable to the other ethnic groups in New Zealand. The main difference lies in avoidable causes of blindness, which appeared to be much higher in the Maori population. The leading cause of avoidable blindness in Maori children is caused by non-accidental injuries.

Compilation of Requirements for Safe Handling of Fluorine and Fluorine-Containing Products of Uranium Hexafluoride Conversion

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ferrada, J.J.

2000-04-03

Public Law (PL) 105-204 requires the U.S. Department of Energy to develop a plan for inclusion in the fiscal year 2000 budget for conversion of the Department's stockpile of depleted uranium hexafluoride (DUF{sub 6}) to a more stable form over an extended period. The conversion process into a more stable form will produce fluorine compounds (e.g., elemental fluorine or hydrofluoric acid) that need to be handled safely. This document compiles the requirements necessary to handle these materials within health and safety standards, which may apply in order to ensure protection of the environment and the safety and health of workersmore » and the public. Fluorine is a pale-yellow gas with a pungent, irritating odor. It is the most reactive nonmetal and will react vigorously with most oxidizable substances at room temperature, frequently with ignition. Fluorine is a severe irritant of the eyes, mucous membranes, skin, and lungs. In humans, the inhalation of high concentrations causes laryngeal spasm and broncospasms, followed by the delayed onset of pulmonary edema. At sublethal levels, severe local irritation and laryngeal spasm will preclude voluntary exposure to high concentrations, unless the individual is trapped or incapacitated. A blast of fluorine gas on the shaved skin of a rabbit causes a second degree burn. Lower concentrations cause severe burns of insidious onset, resulting in ulceration, similar to the effects produced by hydrogen fluoride. Hydrofluoric acid is a colorless, fuming liquid or gas with a pungent odor. It is soluble in water with release of heat. Ingestion of an estimated 1.5 grams produced sudden death without gross pathological damage. Repeated ingestion of small amounts resulted in moderately advanced hardening of the bones. Contact of skin with anhydrous liquid produces severe burns. Inhalation of AHA or aqueous hydrofluoric acid mist or vapors can cause severe respiratory tract irritation that may be fatal. Based on the extreme chemical

To prospectively compare accuracies of transcranial color-coded duplex sonography (TCCS) and transcranial Doppler sonography (TCD) in the diagnosis of middle cerebral artery (MCA) vasospasm. Prospective blinded head-to-head comparison TCD and TCCS methods using digital subtraction angiography (DSA) as the reference standard. Department of Radiology in a tertiary university health center in a metropolitan area. Eighty-one consecutive patients (mean age, 53.9 +/- 13.9 years; 48 women). The indication for DSA was subarachnoid hemorrhage in 71 patients (87.6%), stroke or transient ischemic attack in five patients (6.2%), and other reasons in five patients (6.2%). The MCA was graded as normal, narrowed <50%, and >50% using DSA. The accuracy of ultrasound methods was estimated by total area (Az) under receiver operator characteristic curve. To compare sensitivities of ultrasound methods, McNemar's test was used with mean velocity thresholds of 120 cm/sec for the detection of less advanced, and 200 cm/sec for the more advanced MCA narrowing. Angiographic MCA narrowing 50% in 10 of 135 arteries. Accuracy of TCCS was insignificantly higher than that of TCD in the detection of 50% narrowing, total Az for mean velocity being 0.83 +/- 0.05, 0.77 +/- 0.05, and 0.95 +/- 0.02, 0.86 +/- 0.08, respectively. Sensitivity of TCCS at commonly used threshold of 120 cm/sec for less advanced MCA spasm was significantly better than that of TCD at similar specificity, 55% vs. 39%, p = 0.038, whereas at a threshold of 200 cm/sec used for more advanced spasm, sensitivities and specificities of both methods were not different. The accuracy of TCCS and TCD is similar, but TCCS is more sensitive than TCD in the detection of MCA spasm. Sensitivity of both techniques in the detection of mild and more advanced spasm using 120 cm/sec and 200 cm/sec thresholds, respectively, is poor; however, a larger sample is required to increase precision of our

Adverse testicular effects of Botox® in mature rats

DOE Office of Scientific and Technical Information (OSTI.GOV)

Breikaa, Randa M.; Mosli, Hisham A.; Nagy, Ayman A.

Botox® injections are taking a consistently increasing place in urology. Intracremasteric injections, particularly, have been applied for cryptorchidism and painful testicular spasms. Studies outlining their safety for this use are, however, scanty. Thus, the present study aimed at evaluating possible testicular toxicity of Botox® injections and their effect on male fertility. Mature rats were given intracremasteric Botox® injections (10, 20 and 40 U/kg) three times in a two-week interval. Changes in body and testes weights were examined and gonadosomatic index compared to control group. Semen quality, sperm parameters, fructose, protein, cholesterol and triglycerides contents were assessed. Effects on normal testicularmore » function were investigated by measuring testosterone levels and changes in enzyme activities (lactate dehydrogenase-X and acid phosphatase). To draw a complete picture, changes in oxidative and inflammatory states were examined, in addition to the extent of connective tissue deposition between seminiferous tubules. In an attempt to have more accurate information about possible spermatotoxic effects of Botox®, flowcytometric analysis and histopathological examination were carried out. Botox®-injected rats showed altered testicular physiology and function. Seminiferous tubules were separated by dense fibers, especially with the highest dose. Flowcytometric analysis showed a decrease in mature sperms and histopathology confirmed the findings. The oxidative state was, however, comparable to control group. This study is the first to show that intracremasteric injections of Botox® induce adverse testicular effects evidenced by inhibited spermatogenesis and initiation of histopathological changes. In conclusion, decreased fertility may be a serious problem Botox® injections could cause. - Highlights: • Botox® injections are the trend nowadays, for both medical and non-medical uses. • They were recently suggested for cryptorchidism and

OBJECTIVE To propose a method of redistributing ill-defined causes of death (IDCD) based on the investigation of such causes. METHODS In 2010, an evaluation of the results of investigating the causes of death classified as IDCD in accordance with chapter 18 of the International Classification of Diseases (ICD-10) by the Mortality Information System was performed. The redistribution coefficients were calculated according to the proportional distribution of ill-defined causes reclassified after investigation in any chapter of the ICD-10, except for chapter 18, and used to redistribute the ill-defined causes not investigated and remaining by sex and age. The IDCD redistribution coefficient was compared with two usual methods of redistribution: a) Total redistribution coefficient, based on the proportional distribution of all the defined causes originally notified and b) Non-external redistribution coefficient, similar to the previous, but excluding external causes. RESULTS Of the 97,314 deaths by ill-defined causes reported in 2010, 30.3% were investigated, and 65.5% of those were reclassified as defined causes after the investigation. Endocrine diseases, mental disorders, and maternal causes had a higher representation among the reclassified ill-defined causes, contrary to infectious diseases, neoplasms, and genitourinary diseases, with higher proportions among the defined causes reported. External causes represented 9.3% of the ill-defined causes reclassified. The correction of mortality rates by the total redistribution coefficient and non-external redistribution coefficient increased the magnitude of the rates by a relatively similar factor for most causes, contrary to the IDCD redistribution coefficient that corrected the different causes of death with differentiated weights. CONCLUSIONS The proportional distribution of causes among the ill-defined causes reclassified after investigation was not similar to the original distribution of defined causes. Therefore

Muscle spasm and hypertonia limit mobility in children with spastic cerebral palsy. This double-blind, placebo-controlled, randomized controlled clinical trial studies the clinical efficacy of a low dose of diazepam in enhancing movement in children with spastic cerebral palsy. One hundred and eighty children fulfilled the criteria and were randomly allocated to receive one of two doses of diazepam or placebo at bedtime; 173 completed the study. There was a significant reduction of hypertonia, improvement in the range of passive movement, and an increase in spontaneous movement in the children who received diazepam. There was no report of daytime drowsiness. In developing countries, where cost factors often determine choice of drug, diazepam is a cheap and effective way of relieving spasm and stiffness, optimizing physical therapy and facilitating movement in children with spasticity.

Shock compression and release allow us to evaluate physical deformation and damage mechanisms occurring in extreme environments. SPaSM and LAMMPS molecular dynamics codes were employed to simulate single and polycrystalline tantalum and silicon at strain rates above 108 s-1. Visualization and analysis was accomplished using OVITO, Crystal Analysis Tool, and a redesigned orientation imaging function implemented into SPaSM. A comparison between interatomic potentials for both Si and Ta (as pertaining to shock conditions) is conducted and the influence on phase transformation and plastic relaxation is discussed. Partial dislocations, shear induced disordering, and metastable phase changes are observed in compressed silicon. For tantalum, the role of grain boundary and twin intersections are evaluated for their role in ductile spallation. Finally, the temperature dependent response of both Ta and Si is investigated.

Endocrine causes of calcium disorders.

Endocrine diseases that may cause hypercalcemia and hypocalcemia include hyperparathyroidism, hypoparathyroidism, thyroid disorders, hyperadrenocorticism, hypoadrenocorticism, and less commonly pheochromocytoma and multiple endocrine neoplasias. The differential diagnosis of hypercalcemia may include malignancy (lymphoma, anal sac carcinoma, and squamous cell carcinoma), hyperparathyroidism, vitamin D intoxication, chronic renal disease, hypoadrenocorticism, granulomatous disorders, osteolysis, or spurious causes. Hypocalcemia may be caused by puerperal tetany, pancreatitis, intestinal malabsorption, ethlyene glycol intoxication, acute renal failure, hypopararthyroidism, hypovitaminosis D, hypomagnesemia, and low albumin. This article focuses on the endocrine causes of calcium imbalance and provides diagnostic and therapeutic guidelines for identifying the cause of hypercalcemia and hypocalcemia in veterinary patients.

Unexplained lower abdominal pain associated with sacroiliac joint dysfunction: report of 2 cases.

PubMed

2011-01-01

A 25-year-old woman and a 31-year-old man presented with chronic lower back pain and unexplained lower abdominal pain. Both patients had groin tenderness at the medial border of the anterior superior iliac spine. The results of radiographical and physical examinations suggested sacroiliac joint dysfunction. Sacroiliac joint injection relieved their symptoms, including groin tenderness. In our experience, groin tenderness is highly specific for sacroiliac joint dysfunction. We speculate that spasm of the iliac muscle can cause groin pain and tenderness. Groin pain and a history of unexplained abdominal pain, with lower back pain, are symptoms that suggest sacroiliac joint dysfunction. Additionally, compression of the iliac muscle is a simple and useful maneuver; therefore, it can be used as a screening test for sacroiliac joint dysfunction, alongside other provocation tests.

Hypovitaminosis D and severe hypocalcaemia: the rebirth of an old disease

Pedrosa, Cristina; Ferraria, Nélia; Limbert, Catarina; Lopes, Lurdes

2013-01-01

Vitamin D deficiency, once thought to be eradicated, is becoming a frequent occurence in children, caused mainly by dietary insufficiency. The classical manifestation is rickets, but in infants severe hypocalcaemia may present as stridor, tetany, seizures or, rarely, heart disease. Here, we describe four infants who presented with complications of severe hypocalcaemia secondary to nutritional vitamin D deficiency. (1) Female, 4 months old, several spasms. (2) Male, 8 days old, generalised tonic-clonic seizure. (3) Male, 9 months old, tetany. (4) Male, 4 months old, cardiogenic shock. The cases highlight the importance of child vitamin D supplementation from birth and throughout childhood. We also note that the vitamin D state should be evaluated by the 25(OH)-D value and not the 1,25(OH)2-D. PMID:23729699

Diagnosis of Spasmodic Dysphonia Manifested by Swallowing Difficulty in Videofluoroscopic Swallowing Study

Yeo, Han Gyeol; Lee, Seong Jae; Hyun, Jung Keun

2015-01-01

Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy found no specific problems, an electrodiagnostic study and videofluoroscopic swallowing study (VFSS) were performed to find the cause of dysphagia. The VFSS revealed continuous twitch-like involuntary movement of the laryngeal muscle around the vocal folds. Then, he was diagnosed with spasmodic dysphonia by VFSS, auditory-perceptual voice analysis, and physical examination. So, we report the first case of spasmodic dysphonia accompanied with difficulty swallowing that was confirmed by VFSS. PMID:25932430

Does every event have a cause? An answer is not simple. The notion of cause contains a particular being y acting on being x plus everything that may be called the boundary conditions. These may form necessary and suffcient conditions giving rise to a strong cause, or only necessary conditions, giving rise to a weak cause. These matters are discussed in this article with particular attention being paid to the argumentation of Thomas Aquinas known as prima via. Prima via is the analysis of a cause-effect sequence which leads (according to Thomas) to a First Cause (First Mover). It seems that the extrapolation of the cause-effect sequence to infinity is permissible from the logical point of view. But the possibility of weak causes seems to destroy the cause-effect "line". Here it is perhaps useful to "escape" to the metaphysical abstraction which looks at things sub ratione entitatis. If we ignore space and time (which is characteristic of this abstraction) we are led to believe that the IS of cause is finally unavoidable, which means that from the vantage point of this abstraction, i.e. from the point of view of IS, all causes are strong.

Sensory-Neuropathy-Causing Mutations in ATL3 Cause Aberrant ER Membrane Tethering.

The endoplasmic reticulum (ER) is a complex network of sheets and tubules that is continuously remodeled. The relevance of this membrane dynamics is underscored by the fact that mutations in atlastins (ATLs), the ER fusion proteins in mammals, cause neurodegeneration. How defects in this process disrupt neuronal homeostasis is unclear. Using electron microscopy (EM) volume reconstruction of transfected cells, neurons, and patient fibroblasts, we show that hereditary sensory and autonomic neuropathy (HSAN)-causing ATL3 mutants promote aberrant ER tethering hallmarked by bundles of laterally attached ER tubules. In vitro, these mutants cause excessive liposome tethering, recapitulating the results in cells. Moreover, ATL3 variants retain their dimerization-dependent GTPase activity but are unable to promote membrane fusion, suggesting a defect in an intermediate step of the ATL3 functional cycle. Our data show that the effects of ATL3 mutations on ER network organization go beyond a loss of fusion and shed light on neuropathies caused by atlastin defects. Copyright © 2018 The Author(s).

Computer vision syndrome: a review.

2005-01-01

As computers become part of our everyday life, more and more people are experiencing a variety of ocular symptoms related to computer use. These include eyestrain, tired eyes, irritation, redness, blurred vision, and double vision, collectively referred to as computer vision syndrome. This article describes both the characteristics and treatment modalities that are available at this time. Computer vision syndrome symptoms may be the cause of ocular (ocular-surface abnormalities or accommodative spasms) and/or extraocular (ergonomic) etiologies. However, the major contributor to computer vision syndrome symptoms by far appears to be dry eye. The visual effects of various display characteristics such as lighting, glare, display quality, refresh rates, and radiation are also discussed. Treatment requires a multidirectional approach combining ocular therapy with adjustment of the workstation. Proper lighting, anti-glare filters, ergonomic positioning of computer monitor and regular work breaks may help improve visual comfort. Lubricating eye drops and special computer glasses help relieve ocular surface-related symptoms. More work needs to be done to specifically define the processes that cause computer vision syndrome and to develop and improve effective treatments that successfully address these causes.

Possible complication of bee stings and a review of the cardiac effects of bee stings.

We report the case of a patient who, ∼3 weeks after multiple bee stings, developed a prolonged heart block, syncope and cardiac arrest. This required a temporary pacemaker to be implanted, which was later replaced with a permanent pacemaker. An ECG taken following surgery for a fractured humerus 6 years earlier was reportedly normal. The patient had been a rubber tapper who walked ∼1.5 km/day, but after the bee attack he was no longer able to walk or get up from the bed without experiencing syncope. We presume that the bee venom caused these signs, as well as the resulting heart block, which persisted long after the bee sting had subsided. Since his coronary angiogram was normal we believe he had a Kounis type involvement of the cardiovascular system, namely profound coronary spasm that caused complete heart block that did not recover. Another probable reason for the complete heart block could have been that the bees had consumed the pollen of a rhododendron flower, causing 'grayanotoxin' poisoning and severe heart block. The other effects of bee sting are discussed briefly. 2016 BMJ Publishing Group Ltd.

Image-guided surgery in resection of benign cervicothoracic spinal tumors: a report of two cases.

PubMed

Moore, Timothy; McLain, Robert F

2005-01-01

Osseous spinal tumors are an uncommon cause of persistent axial pain and muscle spasm, but even benign lesions may grow to cause deformity or neurological signs. Traditional treatment approaches to resection can be debilitating even when the tumor is benign. Emerging technologies allow surgeons to diagnose and treat osseous neoplasms while minimizing the collateral damage caused by surgical exposure and tumor excision. Technical considerations are presented through two cases of benign osseous neoplasm occurring in the cervicothoracic spine of competitive athletes, demonstrating the meth-ods used to provide effective treatment while maintaining maximal functional capacity. Stereotactic imaging and intraoperative guidance was used as an adjunct to tumor care in these patients. Used in combination with minimally invasive, microsurgical techniques,stereotactic guidance localized and verified excision margins of benign vertebral lesions, minimizing soft tissue trauma and collateral damage. Computer-assisted stereotactic localization allowed us to successfully ablate these lesions from their anatomically challenging locations, without disrupting the shoulder girdle or neck musculature, and without extensive bony resection. Image guidance can accurately localize and guide excision of benign vertebral lesions while minimizing soft tissue trauma and collateral damage, allowing patients a rapid and complete return to high-demand function.

Infantile spasms (IS) is an age-specific and severe epileptic encephalopathy that occurs in infancy and early childhood and is usually refractory to conventional antiepileptic drugs. Adrenocorticotropic hormone (ACTH) has been the treatment of choice for IS, but ACTH use has been associated with infection and hypertension. Magnesium ion is an N-methyl-D-aspartic acid (NMDA)-noncompetitive antagonist that might inhibit NMDA activity and has antiepileptic and neuroprotective effects. This study compared the efficacy and tolerability of ACTH + magnesium sulfate (MgSO(4)) versus ACTH monotherapy for the treatment of IS. This 24-week, randomized, open-label follow-up study enrolled male and female infants with IS. Patients were randomly assigned to receive ACTH 25 U/d + MgSO(4) 0.25 g/kg/d, or ACTH 25 U/d only (control), intravenously for 3 weeks. Efficacy was assessed over a period of 24 weeks based on seizure frequency, EEG, and Gesell testing of psychomotor skills (subscales: language, motor, adaptive, and personal-social skills; measured using a developmental quotient [DQ] ). Tolerability was assessed by monitoring for adverse events using laboratory analysis and clinical evaluation. Thirty-eight infants were enrolled (23 male, 15 female; median age, 9.2 months; 19 patients per group). At 12 weeks, 14 patients (73.7%) who received ACTH + MgSO(4) and 9 patients (47.4%) in the control group were seizure free. At 24 weeks, seizure-free rates were 12 (63.2%) in the ACTH + MgSO(4) group and 10 (52.6%) in the control group. On EEG, 9 patients (47.4%) in the ACTH + MgSO(4) group achieved complete recovery (normalized EEG), 5 (26.3 %) attained partial improvement (multifocal spike wave), and 5 (26.3%) had no improvement (hypsarrhythmia or modified hypsarrhythmia). At 4 weeks, in the control group, 5 patients (26.3 %) achieved complete recovery, 6 (31.6%) achieved partial improvement, and 8 (42.1%) had no improvement. Of the 12 patients who were seizure free at 24 weeks in

Whole-exome sequencing (WES) has increasingly enabled new pathogenic gene variant identification for undiagnosed neurodevelopmental disorders and provided insights into both gene function and disease biology. Here, we describe seven children with a neurodevelopmental disorder characterized by microcephaly, profound developmental delays and/or intellectual disability, cataracts, severe epilepsy including infantile spasms, irritability, failure to thrive, and stereotypic hand movements. Brain imaging in these individuals reveals delay in myelination and cerebral atrophy. We observe an identical recurrent de novo heterozygous c.892C>T (p.Arg298Trp) variant in the nucleus accumbens associated 1 (NACC1) gene in seven affected individuals. One of the seven individuals is mosaic for this variant. NACC1 encodes a transcriptional repressor implicated in gene expression and has not previously been associated with germline disorders. The probability of finding the same missense NACC1 variant by chance in 7 out of 17,228 individuals who underwent WES for diagnoses of neurodevelopmental phenotypes is extremely small and achieves genome-wide significance (p = 1.25 × 10 -14 ). Selective constraint against missense variants in NACC1 makes this excess of an identical missense variant in all seven individuals more remarkable. Our findings are consistent with a germline recurrent mutational hotspot associated with an allele-specific neurodevelopmental phenotype in NACC1. Copyright © 2017 American Society of Human Genetics.

1990-04-01

A 52-year-old human immunodeficiency virus type 1-seropositive bisexual black man was evaluated at UCLA because of the recent onset of progressive lower-extremity weakness. Initial neurologic examination showed that the patient's distal weakness was greater than his proximal weakness, with bilateral foot drop and electrophysiologic evidence of denervation in the distal lower extremities. Magnetic resonance imaging of the brain and spinal cord disclosed no abnormalities. Subsequent neurologic evaluation 8 months later showed a myelopathy, with progression of lower-extremity weakness, spasticity, and flexor spasms, and urinary incontinence, as well as the peripheral neuropathy noted previously. A second magnetic resonance imaging scan of the brain showed patchy foci of increased signal intensity in white matter and cortex, with mild generalized cerebral and cerebellar atrophy and no lesions in the spinal cord. Specimens of the patient's serum and cerebrospinal fluid contained antibodies to human immunodeficiency virus type 1. Additionally, specimens of his serum and cerebrospinal fluid were tested for antibody to human T-cell leukemia virus type I by Western blotting and radioimmunoprecipitation, and found to be positive for human T-cell leukemia virus type I gag, env, and tax antibodies. The primary cause of severe myelopathy in this patient may be infection with human T-cell leukemia virus type I rather than with human immunodeficiency virus type 1. Treatment with prednisolone resulted in improvement of the lower-extremity weakness, reduction in flexor spasms, and slower but significant improvement in urinary symptoms. Patients who are infected with human immunodeficiency virus type 1 and have unusual motor findings should be tested for concomitant human T-cell leukemia virus type I infection.

A case study of chiropractic management of pregnancy-related heartburn with postulated fetal epigenome implications.

Peterson, Caroline

2012-01-01

This case study reports on chiropractic care for pregnancy-related heartburn. The purpose of this article is to relate the benefit of chiropractic treatment for one individual, to contrast chiropractic management with the biomedical standard of care for pregnancy-related heartburn, and to point to potential epigenetic implications of the standard of care. A 32-year-old woman who was 24 weeks pregnant presented with persistent heartburn that she was treating with ranitidine (Zantac®) and calcium carbonate (Tums®) daily at the initiation of chiropractic care. Findings of the initial examination were thoracic intersegmental dysfunction and pain upon palpation of the diaphragm, with hypertonicity noted. Therapy localization was positive for reflexes associated with the esophagus and lower esophageal sphincter, suggesting spasms. Emotional components also were identified in association with the symptoms by the use of a mind-body therapy called NeuroEmotional Technique. The patient was treated by adjusting the thoracic spine, manually releasing the diaphragm spasms, and releasing the esophageal spasm with an activator (a small hand-held instrument that creates a percussive force). The patient was symptom-free and did not use medication after the fifth treatment. She was followed throughout the remainder of her pregnancy and was asymptomatic and required no further treatment. A larger study should investigate the effectiveness of chiropractic care for the treatment of pregnancy-related heartburn. Copyright © 2012 Elsevier Inc. All rights reserved.

This study tested the hypothesis that vasospasm can trigger coronary plaque injury and acute ischemic myocardial damage. Myocardial infarction-prone strain of the Watanabe heritable hyperlipidemic rabbits received an intravenous bolus of ergonovine maleate (0.45 µmol/kg) during intravenous infusion of norepinephrine (12 nmol/kg per minute) to provoke coronary spasm in vivo. After this treatment, coronary angiography demonstrated vasospasm, and the ECG showed ischemic abnormalities (ST depression/elevation and T-wave inversion) in 77% of animals (23/30). These changes normalized after nitroglycerin injection. In rabbits that demonstrated these ECG findings for >20 minutes, echocardiograms showed left ventricular wall motion abnormality. Serum levels of heart-type fatty acid-binding protein, cardiac troponin-I, and myoglobin increased markedly 4 hours after spasm provocation. In coronary lesions of myocardial infarction-prone strain of the Watanabe heritable hyperlipidemic rabbits with provoked coronary spasm, we observed intimal injury in 60.9% in the form of endothelial cell protrusions (39.1%), denudation (30.4%), and macrophage extravasation (56.5%). Plaque disruption with luminal thrombus, however, was only seen in 2 of 23 animals (8.7%), and mural microthrombus was rarely observed (4.3%). These observations show that provocation of vasospasm in myocardial infarction-prone strain of the Watanabe heritable hyperlipidemic rabbits associates with subsequent ischemic myocardial damage. Although treatment with spasmogens altered aspects of plaque morphology, for example, endothelial protrusion and macrophage emigration, thrombosis was rare in these animals with chronic atherosclerotic disease.

Laboratory stress: what causes it?

PubMed

Griffin, P; Klun, C L

1980-07-01

One hundred-fifty questionnaires were distributed to gather specific information about the causes of stress in the hospital-employed medical technologist (MT). Sixty-four percent were returned. The results were analyzed using Friedman's two-way analysis of variance by ranks. Although the causes of stress to the medical laboratorian are many and they are affected by variables within the worker, certain items are more significant causes of stress than others. Physicians, stats, the need for accuracy, lack of communication, errors, and overwork are major causes of stress. These are the stressors that must be controlled or modified to reduce stress to the MT employed in a hospital laboratory.

The causes of Permanent Childhood Hearing Impairment (PCHI) are often quoted as being hereditary in 50%, acquired in 25%, and unknown in 25% of cases. Interest in the causes of PCHI has grown recently due to increasing diagnostic possibilities. We investigated the evidence for the reported distribution of these causes. Population-based study and a systematic review. Inclusion criteria for population-based study: children born between 2003 and 2005, resident in The Netherlands at birth, known at an Audiology Center with PCHI at the age of 3-5 years. The causes of PCHI were determined prospectively by detection of congenital cytomegalovirus on dried blood spots and/or genetic diagnostic investigations in addition to reviewing data from medical records. A systematic review was carried out using three terms (hearing loss, infant, and etiology) and limited to articles published between January 1997 and July 2009. Main outcome measures were: the (weighted) proportions of the various causes of PCHI following diagnostic investigations. In the study-population (n = 185) a hereditary cause was found in 38.9%, acquired cause in 29.7%, miscellaneous cause in 7.1%, and the cause remained unknown in 24.3%. The systematic review of the literature (n = 9 articles) resulted in a weighted mean of 30.4% hereditary, 19.2% acquired, and 48.3% unknown causes of PCHI. The systematic review and the results of the population-based study provided little support for the generally accepted distribution of causes of PCHI.

Ijaz, Umar; Habib, Asad; Rathore, Hassan Sajjad

2018-03-01

Unilateral cyclitis leading to myopia is a rare and clinical relevant entity. In clinical settings, pseudomyopia is generally encountered in the form of accommodative spasm, which is always bilateral. Cyclitis due to inflammation, on the other hand, can cause pseudomyopia unilaterally and it is a very rare presentation. A young male with acute anterior uveitis, presented with acute episode of unilateral myopia. When patient was examined on first visit, there were no cells in anterior chamber; so he was started on cycloplegic eye drops, but his condition didn't improve. Examination on subsequent visit revealed cellular reaction in anterior chamber and narrowing of anterior chamber angles on anterior segment optical coherence tomography (OCT). Treatment for uveitis was started and patient's visual acuity and refractive error improved. Pseudomyopia is a known complication of several drugs and certain medical conditions. The possible mechanism is supraciliary exudation causing relaxation of zonular fibers and increased convexity of the crystalline lens. Myopia in the setting of a mild cellular reaction can easily be missed and has not been reported yet to the best of authors' literature search.

Malignant hyperthermia (MH) can develop after contact with volatile anesthetics (halothane, enflurane, isoflurane, sevoflurane, and desflurane) as well as succinylcholine and cause hypermetabolism during anesthesia, which is associated with high mortality when untreated. Early diagnosis and treatment could be life-saving. During cardiac surgery, hypothermia and cardiopulmonary bypass make the diagnosis of MH extremely challenging compared with other settings such as general surgery. We herein report 2 cases of MH, graded as "very likely" or "almost certain" based on the MH clinical grading scale. A 14-month-old infant and a 53-year-old male underwent surgery for severe pulmonary valve stenosis and mitral valve replacement, respectively. Both of them were extubated on the operation day, but they deteriorated with the development of high-grade fever, hypotension, renal failure, and acidosis. The first case had muscle spasms. Unfortunately, the delayed symptoms of MH in the early postoperative course were not diagnosed in these 2 cases, which caused permanent neurologic damage in the first case and death in the second one. However, the infant was discharged from the hospital after 2 months.

What is in a cause? Exploring the relationship between genetic cause and felt stigma

Purpose Concern over stigma as a consequence of genetic testing has grown in response to the recent increase in genetic research and testing resulting from the Human Genome Project. However, whether a genetic or hereditary basis necessarily confers a stigma to a condition remains unexamined. Methods We performed a qualitative interview study with 86 individuals with one of four conditions: deafness or hearing loss, breast cancer, sickle cell disease, and cystic fibrosis. The first two groups were divided approximately between people who ascribed their conditions to a genetic or hereditary cause and those who did not. Results Respondents interpreted genetic or hereditary causes and nongenetic causes in a variety of ways. Subjects with breast cancer reported the most consistently negative interpretation of genetic cause. This response concerned future ill health, not an enduring sense of stigma. Deaf and hard of hearing subjects provided the most consistently positive comments about a genetic or hereditary basis to their condition, casting familial hearing loss as a vital component of group and individual identity. Respondents with sickle cell disease and cystic fibrosis offered similar and positive interpretations of the genetic cause of their condition insofar as it meant their conditions were not contagious. Conclusions Although some subjects report feeling stigmatized as a result of their condition, this stigmatization is not uniformly associated with the condition’s cause, genetic or otherwise. Instead, stigma emerges from a variety of sources in the context of the lived experience of a particular condition. PMID:16418597

Psychic trauma as cause of death.

PubMed

Terranova, C; Snenghi, R; Thiene, G; Ferrara, S D

2011-01-01

of study Psychic trauma is described as the action of 'an emotionally overwhelming factor' capable of causing neurovegetative alterations leading to transitory or persisting bodily changes. The medico-legal concept of psychic trauma and its definition as a cause in penal cases is debated. The authors present three cases of death after psychic trauma, and discuss the definition of cause within the penal ambit of identified 'emotionally overwhelming factors'. The methodological approach to ascertainment and criterion-based assessment in each case involved the following phases: (1) examination of circumstantial evidence, clinical records and documentation; (2) autopsy; (3) ascertainment of cause of death; and (4) ascertainment of psychic trauma, and its coexisting relationship with the cause of death. The results and assessment of each of the three cases are discussed from the viewpoint of the causal connotation of psychic trauma. In the cases presented, psychic trauma caused death, as deduced from assessment of the type of externally caused emotional insult, the subjects' personal characteristics and the circumstances of the event causing death. In cases of death due to psychic trauma, careful methodological ascertainment is essential, with the double aim of defining 'emotionally overwhelming factors' as a significant cause of death from the penal point of view, and of identifying the responsibility of third parties involved in the death event and associated dynamics of homicide.

Microtia is a spectrum of congenital deformities. Approximately, half of the patients are associated with hemifacial microtia. The birth rate of microtia ranges from 2 per 10,000 to 17.4 per 10,000. Microtia and limb deformities sometimes occurred simultaneously as described in the literature. In this report, the patient was found to be with unilateral microtia combined with bilateral split sole of feet, deformed middle fingers on both hands, and café-au-lait spots on the trunk. Despite a thorough literature search, the authors could not achieve a satisfactory diagnosis for the current case with respect to the type of anomalies seen in the case.

Wanderley, D M; Litvoc, J

1994-02-01

Death certificates of all persons who died in in the State of S.Paulo, Brazil and which presented Chagas' disease as the principal cause of death, were studied with a view to analysing the existing additional information available as to contributory causes. After a direct reading of the 1,308 death certificates, the contributory causes were identified and registered. They were mentioned in 261 (20%) of the certificates, 185 of them presenting only one, and 75 two of them. The 6 more frequent contributory causes were: "megas", embolism, chronic pulmonary disease, infections (other than Chagas' disease), arterial hypertension and malnutrition. When analysing the presence of the contributory causes in two groups-persons of less than 50 years old, and those older than 50 a higher proportion of them was observed in the older group and a distinct profile of causes was found for each group. No statistic association was observed between contributory causes and sex or site of residence.

Anthropogenic climate change is predicted to be a major cause of species extinctions in the next 100 years. But what will actually cause these extinctions? For example, will it be limited physiological tolerance to high temperatures, changing biotic interactions or other factors? Here, we systematically review the proximate causes of climate-change related extinctions and their empirical support. We find 136 case studies of climatic impacts that are potentially relevant to this topic. However, only seven identified proximate causes of demonstrated local extinctions due to anthropogenic climate change. Among these seven studies, the proximate causes vary widely. Surprisingly, none show a straightforward relationship between local extinction and limited tolerances to high temperature. Instead, many studies implicate species interactions as an important proximate cause, especially decreases in food availability. We find very similar patterns in studies showing decreases in abundance associated with climate change, and in those studies showing impacts of climatic oscillations. Collectively, these results highlight our disturbingly limited knowledge of this crucial issue but also support the idea that changing species interactions are an important cause of documented population declines and extinctions related to climate change. Finally, we briefly outline general research strategies for identifying these proximate causes in future studies. PMID:23075836

Ruling out secondary causes of hypertension.

PubMed

Ott, Christian; Schneider, Markus P; Schmieder, Roland E

2013-05-01

In the majority of hypertensive patients, no particular cause for abnormal blood pressure is evident (primary or essential hypertension). In contrast, in the minority of patients with secondary hypertension a specific underlying cause is responsible for the elevated blood pressure. The prevalence of secondary hypertension is higher in patients with resistant hypertension than in the general hypertensive population and increases with age. The list of secondary forms of hypertension is long and prevalence of the individual causes of secondary hypertension varies. Hence, this review divides them into two categories: common causes and rare causes. If appropriately diagnosed and treated, patients with a secondary form of hypertension might be cured, or at least show an improvement in their blood pressure control. Consequently, screening for secondary causes of hypertension plays an essential part in the care of patients with arterial hypertension. If the basal work-up raises the suspicion of a secondary cause of hypertension, specific diagnostic procedures become necessary, some of which can be performed by primary care physicians, while others require specialist input.

Rehabilitation of Bell's palsy patient with complete dentures.

Facial nerve disorders may be of sudden onset and more often of unknown etiology. Edema of the facial nerve within the fallopian canal results in Bell's palsy. This causes compression of the nerve and affects the microcirculation. Many authors have suggested treatment for facial nerve paralysis ranging from simple physiotherapy to complicated microvascular decompression. It more often results in symptoms like synkinesis and muscle spasm after the decompression surgery of the nerve because of the inability to arrange the nerve fibers within the canal. The treatment choice also depends on patient's age, extent of the nerve damage, and patient's needs and desires. Many patients who cannot be rehabilitated functionally can be treated for esthetics of the involved muscles. This case report elaborates about a patient who was rehabilitated for esthetics and to some extent for function.

Butorphanol in perspective.

PubMed

Rosow, C E

1988-01-01

Butorphanol tartrate is a highly effective opioid agonist-antagonist analgesic with qualitative as well as quantitative differences from the pure agonists. These differences are thought to be due to interaction with a distinct subset of opioid receptors. Although it relieves severe pain, the drug does not usually elevate mood, and it may occasionally cause dysphoria. Counterbalancing its disadvantages is a wealth of clinical experience with the drug showing an impressive record of safety. Butorphanol produces limited respiratory depression and smooth muscle spasm, and both effects are reversible with naloxone. The most prominent side effect is sedation, a property that is generally quite useful in the perioperative period. Butorphanol is a weak morphine antagonist, so it may interact with agonists like morphine or fentanyl. The chief advantages of this agent are its low toxicity and very low potential for abuse.

We present regional patterns and trends in all-cause mortality and leading causes of death in American Indians and Alaska Natives (AI/ANs). US National Death Index records were linked with Indian Health Service (IHS) registration records to identify AI/AN deaths misclassified as non-AI/AN. We analyzed temporal trends for 1990 to 2009 and comparisons between non-Hispanic AI/AN and non-Hispanic White persons by geographic region for 1999 to 2009. Results focus on IHS Contract Health Service Delivery Area counties in which less race misclassification occurs. From 1990 to 2009 AI/AN persons did not experience the significant decreases in all-cause mortality seen for Whites. For 1999 to 2009 the all-cause death rate in CHSDA counties for AI/AN persons was 46% more than that for Whites. Death rates for AI/AN persons varied as much as 50% among regions. Except for heart disease and cancer, subsequent ranking of specific causes of death differed considerably between AI/AN and White persons. AI/AN populations continue to experience much higher death rates than Whites. Patterns of mortality are strongly influenced by the high incidence of diabetes, smoking prevalence, problem drinking, and social determinants. Much of the observed excess mortality can be addressed through known public health interventions.

To assess the clinical outcomes following botulinum neurotoxin type A (BoNT-A) treatment with an individualized injection technique based on the types of spasms and to compare the results of the individualized injection technique with those of the conventional injection technique in the same patients. From November 2011 to July 2013, 77 BoNT-A injections were performed in 38 patients. Eighteen patients were treated with conventional BoNT-A injections before 2011, and 20 patients were referred to our hospital for unsatisfactory results after a conventional injection technique. We classified the patients by spasm-dominant sites: the lateral orbital area, representing the orbital orbicularis-dominant group (ODG); the glabella, representing the corrugator-dominant group (CDG); and the ptosis, representing the palpebral part of the orbicularis-dominant group (PDG). We increased the injection dose into the spasm-dominant sites of the blepharospasm groups. We assessed subjective symptom scores (functional disability score, FDS) after treatment. This study included 38 patients (26 women, 12 men; mean age, 60.6 ± 10.9 years). There were 21 patients in the ODG, 10 patients in the CDG, and 7 patients in the PDG. Mean ages were 59.7 ± 12.6, 59.8 ± 8.5, and 66.8 ± 9.0 years, and mean BoNT-A injection dose was 38.8 ± 11.2, 38.8 ± 11.2, and 38.8 ± 10.8 U in each group, respectively (p = 0.44, 0.82 Kruskal-Wallis test). Mean FDS after injection was 1.7 ± 0.7 in the ODG, 1.4 ± 0.8 in the CDG, and 1.2 ± 0.3 in the PDG. There were significant differences in reading and job scale among the three groups. In a comparison between the conventional and individualized injection techniques, there was a significant improvement in mean FDS and in the reading scale in the PDG with the individualized injection technique. The success rate was 92.1% in the conventional injection group and 94.1% in the individualized injection group. The individualized injection technique of Bo

Common Cause Failures (CCFs) are a known and documented phenomenon that defeats system redundancy. CCFS are a set of dependent type of failures that can be caused by: system environments; manufacturing; transportation; storage; maintenance; and assembly, as examples. Since there are many factors that contribute to CCFs, the effects can be reduced, but they are difficult to eliminate entirely. Furthermore, failure databases sometimes fail to differentiate between independent and CCF (dependent) failure and data is limited, especially for launch vehicles. The Probabilistic Risk Assessment (PRA) of NASA's Safety and Mission Assurance Directorate at Marshal Space Flight Center (MFSC) is using generic data from the Nuclear Regulatory Commission's database of common cause failures at nuclear power plants to estimate CCF due to the lack of a more appropriate data source. There remains uncertainty in the actual magnitude of the common cause risk estimates for different systems at this stage of the design. Given the limited data about launch vehicle CCF and that launch vehicles are a highly redundant system by design, it is important to make design decisions to account for a range of values for independent and CCFs. When investigating the design of the one-out-of-two component redundant system for launch vehicles, a response surface was constructed to represent the impact of the independent failure rate versus a common cause beta factor effect on a system's failure probability. This presentation will define a CCF and review estimation calculations. It gives a summary of reduction methodologies and a review of examples of historical CCFs. Finally, it presents the response surface and discusses the results of the different CCFs on the reliability of a one-out-of-two system.

The New Classification of Seizures by the International League Against Epilepsy 2017.

PubMed

Fisher, Robert S

2017-06-01

This review presents the newly developed International League Against Epilepsy (ILAE) 2017 classification of seizure types. The fundamental distinction is between seizures that begin focally in one hemisphere of the brain, generalized onset seizures that apparently originate in both hemispheres, and seizures of unknown onset. Focal seizures optionally can be subclassified according to whether awareness (a surrogate marker for consciousness) is intact or impaired. The next level of classification for focal seizures is motor (with subgroups automatisms, atonic, clonic, epileptic spasms, hyperkinetic, myoclonic, tonic), non-motor (with subgroups autonomic, behavior arrest, cognitive, emotional, sensory), and focal to bilateral tonic-clonic. Generalized seizures are categorized as motor (tonic-clonic, clonic, tonic, myoclonic, myoclonic-tonic-clonic, myoclonic-atonic, atonic, epileptic spasms) and non-motor/absence (typical, atypical, myoclonic, eyelid myoclonia). The classification allows new types of focal seizures and a few new generalized seizures, and clarifies terms used to name seizures.

Using expert knowledge to incorporate uncertainty in cause-of-death assignments for modeling of cause-specific mortality

Implicit and explicit use of expert knowledge to inform ecological analyses is becoming increasingly common because it often represents the sole source of information in many circumstances. Thus, there is a need to develop statistical methods that explicitly incorporate expert knowledge, and can successfully leverage this information while properly accounting for associated uncertainty during analysis. Studies of cause-specific mortality provide an example of implicit use of expert knowledge when causes-of-death are uncertain and assigned based on the observer's knowledge of the most likely cause. To explicitly incorporate this use of expert knowledge and the associated uncertainty, we developed a statistical model for estimating cause-specific mortality using a data augmentation approach within a Bayesian hierarchical framework. Specifically, for each mortality event, we elicited the observer's belief of cause-of-death by having them specify the probability that the death was due to each potential cause. These probabilities were then used as prior predictive values within our framework. This hierarchical framework permitted a simple and rigorous estimation method that was easily modified to include covariate effects and regularizing terms. Although applied to survival analysis, this method can be extended to any event-time analysis with multiple event types, for which there is uncertainty regarding the true outcome. We conducted simulations to determine how our framework compared to traditional approaches that use expert knowledge implicitly and assume that cause-of-death is specified accurately. Simulation results supported the inclusion of observer uncertainty in cause-of-death assignment in modeling of cause-specific mortality to improve model performance and inference. Finally, we applied the statistical model we developed and a traditional method to cause-specific survival data for white-tailed deer, and compared results. We demonstrate that model selection

Little is known about aetiology and morbidity and clinical characteristics of pyogenic liver abscess caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae. An analysis between pyogenic liver abscess patients caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae isolates and those caused by non-extended-spectrum beta-lactamase-producing Enterobacteriaceae was performed. Among 817 pyogenic liver abscess patients, there were 176 patients (21.5%) with pyogenic liver abscess of biliary origin, and 67 pyogenic liver abscess patients (8.2%) caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae isolates (mainly Escherichia coli and Klebsiella pneumoniae). Of 176 pyogenic liver abscess patients related to biliary disorders, there were 48 pyogenic liver abscess patients (27.3%) caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae. Within 67 pyogenic liver abscess patients caused by Enterobacteriaceae expressing extended-spectrum beta-lactamases, the occurrences of 48 pyogenic liver abscess patients (71.6%) were associated with biliary disorders. When compared with pyogenic liver abscess patients caused by non-extended-spectrum beta-lactamase-producing Enterobacteriaceae, there were significantly greater incidences of polymicrobial infections, bacteremia, pulmonary infection, recurrence and death in pyogenic liver abscess patients caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae. Carbapenems remain mainstay drugs against extended-spectrum beta-lactamase-producing E. coli and K. pneumoniae. Independent risk factors for occurrence of pyogenic liver abscess caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae were biliary disorders including extra- and intrahepatic cholangiolithiasis and an abnormal bilioenteric communication between bile and gut, a treatment history of malignancy such as operation and chemotherapy, pulmonary infection, and diabetes mellitus

Vulvovaginitis: causes and management.

Pierce, A M; Hart, C A

1992-01-01

Over a period of 33 months in a paediatric accident and emergency department, the clinical pattern and possible causes of vulvovaginitis were studied prospectively in 200 girls presenting with genital discharge, irritation, pain, or redness. The major causes were poor hygiene and threadworms. The suspicion of sexual abuse arose in a few girls but no organisms of sexually transmitted disease were found. Urinary symptoms were common but only 20 patients had a significant bacteriuria and 40 had sterile pyuria. Specific skin problems occurred in 28 cases. Simple measures to improve hygiene and treatment of threadworms gave effective relief. Genital irritation caused urinary symptoms with no clinical evidence of infection, and it is advised that antibiotic treatment should await urine culture. Specific skin problems require help from a dermatologist. The possibility of sexual abuse must be considered especially if the vulvovaginitis is persistent or recurrent after adequate treatment.

Background/Objective: Pseudomeningocele is most commonly the result of a rent in the meninges during spine surgery. Noniatrogenic causes exist but are rare. Pseudomeningoceles may heal spontaneously, but they may also slowly enlarge. They rarely present as a mass within the abdomen. The objective of this study was to present the first case report of hydronephrosis secondary to lumbar pseudomeningocele. Design: Single case report and literature review. Methods: Single case report. Results: This man had undergone extensive lumbar spine surgery for pain and spondylolisthesis. He subsequently developed a pseudomeningocele that caused hydronephrosis of the left kidney. He was treated with surgical intervention and had resolution of his hydronephrosis and his flank and groin pain. He also had improvement of his back pain. Conclusions: This report shows an unusual cause of hydronephrosis—a pseudomeningocele presenting as an abdominal mass that compressed the ureter. PMID:19264055

Animal models have provided a wealth of information on mechanisms of epileptogenesis and comorbidogenesis, and have significantly advanced our ability to investigate the potential of new therapies. Processes implicating brain inflammation have been increasingly observed in epilepsy research. Herein we discuss the progress on animal models of epilepsy and comorbidities that inform us on the potential role of inflammation in epileptogenesis and comorbidity pathogenesis in rodent models of West syndrome and the Theiler's murine encephalomyelitis virus (TMEV) mouse model of viral encephalitis-induced epilepsy. Rat models of infantile spasms were generated in rat pups after right intracerebral injections of proinflammatory compounds (lipopolysaccharides with or without doxorubicin, or cytokines) and were longitudinally monitored for epileptic spasms and neurodevelopmental and cognitive deficits. Anti-inflammatory treatments were tested after the onset of spasms. The TMEV mouse model was induced with intracerebral administration of TMEV and prospective monitoring for handling-induced seizures or seizure susceptibility, as well as long-term evaluations of behavioral comorbidities of epilepsy. Inflammatory processes are evident in both models and are implicated in the pathogenesis of the observed seizures and comorbidities. A common feature of these models, based on the data so far available, is their pharmacoresistant profile. The presented data support the role of inflammatory pathways in epileptogenesis and comorbidities in two distinct epilepsy models. Pharmacoresistance is a common feature of both inflammation-based models. Utilization of these models may facilitate the identification of age-specific, syndrome- or etiology-specific therapies for the epilepsies and attendant comorbidities, including the drug-resistant forms.

To investigate the efficacy, safety and tolerability of paraspinal administration of botulinum neurotoxin type A (BoNT-A) in patients with chronic low back ache (LBA). Eight patients with chronic LBA were injected with BoNT-A at three sites on either side of lumbar paraspinal muscles. The patients rated their pain intensity using a visual analogue scale (VAS) from 0 to 10, and our physiotherapist assessed the paraspinal muscle spasm using a functional scale (FS) from 0 to 5. The improvement in both VAS and FS 30, 60 and 90 days after BoNT-A from baseline was analyzed separately using paired t test. The correlation between the muscle spasm (FS) and pain relief (VAS) was analyzed using the Spearman's rank correlation coefficient test. The level of statistical significance was p < 0.05. Five (63%) patients showed a remarkable recovery in VAS and FS, whereas 2 (25%) patients showed improvement only in FS. Statistically significant improvement was achieved in VAS and FS independently 30 days (p < 0.02 and p < 0.02, respectively), 60 days (p < 0.01 and p < 0.001, respectively) and 90 days (p < 0.02 and p < 0.001, respectively) after treatment. Pain relief started early and it was independent of relief of muscle spasm 30 days after treatment (r = 0.685; p > 0.05). With this limited study, we have demonstrated that the paraspinal injection of BoNT-A is effective in relieving chronic LBA without producing side effects. The injection is an easy procedure, well tolerated and did not require anesthesia or imaging technique.

OBJECTIVE Stereotactic radiosurgery (SRS) is an important alternative management option for patients with small- and medium-sized vestibular schwannomas (VSs). Its use in the treatment of large tumors, however, is still being debated. The authors reviewed their recent experience to assess the potential role of SRS in larger-sized VSs. METHODS Between 2000 and 2014, 35 patients with large VSs, defined as having both a single dimension > 3 cm and a volume > 10 cm 3 , underwent Gamma Knife radiosurgery (GKRS). Nine patients (25.7%) had previously undergone resection. The median total volume covered in this group of patients was 14.8 cm 3 (range 10.3-24.5 cm 3 ). The median tumor margin dose was 11 Gy (range 10-12 Gy). RESULTS The median follow-up duration was 48 months (range 6-156 months). All 35 patients had regular MRI follow-up examinations. Twenty tumors (57.1%) had a volume reduction of greater than 50%, 5 (14.3%) had a volume reduction of 15%-50%, 5 (14.3%) were stable in size (volume change < 15%), and 5 (14.3%) had larger volumes (all of these lesions were eventually resected). Four patients (11.4%) underwent resection within 9 months to 6 years because of progressive symptoms. One patient (2.9%) had open surgery for new-onset intractable trigeminal neuralgia at 48 months after GKRS. Two patients (5.7%) who developed a symptomatic cyst underwent placement of a cystoperitoneal shunt. Eight (66%) of 12 patients with pre-GKRS trigeminal sensory dysfunction had hypoesthesia relief. One hemifacial spasm completely resolved 3 years after treatment. Seven patients with facial weakness experienced no deterioration after GKRS. Two of 3 patients with serviceable hearing before GKRS deteriorated while 1 patient retained the same level of hearing. Two patients improved from severe hearing loss to pure tone audiometry less than 50 dB. The authors found borderline statistical significance for post-GKRS tumor enlargement for later resection (p = 0.05, HR 9.97, CI 0

All-cause and cause-specific mortality of social assistance recipients in Norway: a register-based follow-up study.

To investigate the mortality among social assistance recipients, who are among the most marginalized people in Norway. Cause-specific mortality was analysed in an attempt to explain the excess mortality. Previous research has suggested that social disadvantage leads to higher mortality from all causes, whereas others have found substantial variation when studying separate causes. The impact of the various causes will influence policy recommendations. Data were compiled through linking between Norwegian administrative records. The entire population born between 1935 and 1974 (2,297,621 people) was followed with respect to social assistance and death from 1993 to 2003. Cause-specific, age-standardized mortality rates for social assistance recipients and the rest of the population were calculated, and both the absolute (rate difference) and relative (rate ratio) rates were measured. The rate ratio for total mortality was 3.1 for men and 2.5 for women for the comparison between social assistance recipients and the general population. The mortality among social assistance recipients was higher for all causes, but the magnitude differed considerably, depending on the cause. The rate ratio for men ranged from 1.2 for non-smoking-related cancer to 18.8 for alcohol- and drug-related causes. Alcohol-and drug-related and violent causes together contributed to half of the excess mortality for men and one-third for women. The mortality of this socially disadvantaged group was considerably higher than that of the general population, and this difference reflected mainly drug-related causes.

Inflammation and oedema of the facial nerve are implicated in causing Bell's palsy. Corticosteroids have a potent anti-inflammatory action that should minimise nerve damage. This is an update of a review first published in 2002 and last updated in 2010. To determine the effectiveness and safety of corticosteroid therapy in people with Bell's palsy. On 4 March 2016, we searched the Cochrane Neuromuscular Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and LILACS. We reviewed the bibliographies of the randomised trials and contacted known experts in the field to identify additional published or unpublished trials. We also searched clinical trials registries for ongoing trials. Randomised trials and quasi-randomised trials comparing different routes of administration and dosage schemes of corticosteroid or adrenocorticotrophic hormone therapy versus a control group receiving no therapy considered effective for this condition, unless the same therapy was given in a similar way to the experimental group. We used standard Cochrane methodology. The main outcome of interest was incomplete recovery of facial motor function (i.e. residual facial weakness). Secondary outcomes were cosmetically disabling persistent sequelae, development of motor synkinesis or autonomic dysfunction (i.e. hemifacial spasm, crocodile tears) and adverse effects of corticosteroid therapy manifested during follow-up. We identified seven trials, with 895 evaluable participants for this review. All provided data suitable for the primary outcome meta-analysis. One of the trials was new since the last version of this Cochrane systematic review. Risk of bias in the older, smaller studies included some unclear- or high-risk assessments, whereas we deemed the larger studies at low risk of bias. Overall, 79/452 (17%) participants allocated to corticosteroids had incomplete recovery of facial motor function six months or more after randomisation

While heart disease, cancer, and injuries are leading proximate causes of death, research has demonstrated that about half of all deaths in the United States are actually due to preventable causes, including tobacco use, poor diet, and physical inactivity. Using state vital statistics data and findings from national studies, we report on the trends in the preventable causes of death in Wisconsin from 1992 to 2004. The leading proximate causes of death in Wisconsin were obtained from Wisconsin Interactive Statistics on Health (WISH) data derived from individual death certificates. Information on the preventable causes of death was either obtained from the underlying cause information on the death certificate or from peer-reviewed epidemiologic studies. While the overall age-adjusted death rate declined from 837 to 744 per 100,000 from 1992 to 2004, the top 10 causes of death remain largely unchanged. Nearly half of the deaths in Wisconsin in 2004 resulted from 11 preventable causes, similar to the findings in 1992. Epidemiologic research demonstrates that nearly half of all deaths in Wisconsin are due to preventable causes. Programs and policies must continue to address these preventable causes of disease if Wisconsin is to meet its goal of promoting and protecting population health.

Purpose We compared mortality rates among state prisoners and other state residents to identify prisoners’ healthcare needs Methods We linked North Carolina prison records with state death records for 1995-2005 to estimate all-cause and cause-specific death rates among Black and White male prisoners aged 20-79 years, and used standardized mortality ratios (SMRs) to compare these observed deaths with the expected number based on death rates among state residents Results The all-cause SMR of Black prisoners was 0.52 (95%CI: 0.48 0.57), with fewer deaths than expected from accidents, homicides, cardiovascular disease and cancer. The all-cause SMR of White prisoners was 1.12 (95%CI: 1.01, 1.25) with fewer deaths than expected for accidents, but more deaths than expected from viral hepatitis, liver disease, cancer, chronic lower respiratory disease, and HIV. Conclusions Mortality of Black prisoners was lower than that of Black state residents for both traumatic and chronic causes of death. Mortality of White prisoners was lower than that of White state residents for accidents, but higher for several chronic causes of death. Future studies should investigate the effect of prisoners’ pre-incarceration and in-prison morbidity, the prison environment, and prison healthcare on prisoners’ patterns of mortality. PMID:21737304

Global and regional causes of death.

Assessing the causes of death across all regions of the world requires a framework for integrating, and analysing, the fragmentary information that is available on numbers of deaths and their cause distributions. This paper provides an overview of the met and methods used by the World Health Organization to develop global-, regional- and country-level estimates of mortality for a comprehensive set of causes, and provides an overview of global and regional levels and patterns of causes of death for the year 2004. The paper also examines some of the data gaps, uncertainties and limitations in the resulting mortality estimates. Deaths for 136 disease and injury causes were estimated from available death registration data (111 countries), sample death registration data (India and China), and for the remaining countries from census and survey information, and cause-of-death models. Population-based epidemiological studies and notifications systems also contributed to estimating mortality for 21 of these causes (representing 28% of deaths globally, 58% in Africa). Ischaemic heart disease and cerebrovascular disease are the leading causes of death, followed by lower respiratory infections, chronic obstructive pulmonary disease and diarrhoeal diseases. AIDS and TB are the sixth and seventh most common causes of death, respectively, lower than in previous estimates. One-half of all child deaths are from four preventable and treatable communicable diseases. Globally, around 6 in 10 deaths are from non-communicable diseases, 3 from communicable diseases and 1 from injuries. Injury mortality is highest in South-East Asia, Latin America and the Eastern Mediterranean region. These results illustrate continuing huge disparities in risks and causes of death across the world. Global mortality analyses of the type reported here have been criticized for making estimates of mortality for regions with limited, incomplete and uncertain data. Estimates presented here use a range of

Treatment of Gastrointestinal Sphincters Spasms with Botulinum Toxin A

Botulinum toxin A inhibits neuromuscular transmission. It has become a drug with many indications. The range of clinical applications has grown to encompass several neurological and non-neurological conditions. One of the most recent achievements in the field is the observation that botulinum toxin A provides benefit in diseases of the gastrointestinal tract. Although toxin blocks cholinergic nerve endings in the autonomic nervous system, it has also been shown that it does not block non-adrenergic non-cholinergic responses mediated by nitric oxide. This has promoted further interest in using botulinum toxin A as a treatment for overactive smooth muscles and sphincters. The introduction of this therapy has made the treatment of several clinical conditions easier, in the outpatient setting, at a lower cost and without permanent complications. This review presents current data on the use of botulinum toxin A in the treatment of pathological conditions of the gastrointestinal tract. PMID:26035487

This epileptic disorder has become a classic topic for neuropediatricians and the interest is documented by the large number of publications on this subject. The relative frequency among the epileptic syndromes is an another reason why not only neuropediatricians but also general pediatricians must be fully informed about diagnostic, clinical, imaging and genetic aspects. Early diagnosis is of paramount importance in order to obtain even complete results in patients with so called idiopathic situations. A number of problems are still to be solved. There is no agreement on the type and the schedule of treatment. A common denominator about this problem is not jet available even if some advances in this regard have been accomplished. Of paramount importance is an accurate clinical and laboratory examination as a prerequisite regarding prognosis and results of therapy in every single case. However, even if more than 170 years have elapsed since the first communication of dr. West on the peculiar syndrome that his child was suffering of, the interest of scientists on this subject has now been enriched and rewarded. PMID:20181122

The population of the Pacific Melanesian country of Vanuatu was 234,000 at the 2009 census. Apart from subsistence activities, economic activity includes tourism and agriculture. Current completeness of vital registration is considered too low to be usable for national statistics; mortality and life expectancy (LE) are derived from indirect demographic estimates from censuses/surveys. Some cause of death (CoD) data are available to provide information on major causes of premature death. Deaths 2001-2007 were coded for cause (ICDv10) for ages 0-59 years from: hospital separations (HS) (n = 636), hospital medical certificates (MC) of death (n = 1,169), and monthly reports from community health facilities (CHF) (n = 1,212). Ill-defined causes were 3 % for hospital deaths and 20 % from CHF. Proportional mortality was calculated by cause (excluding ill-defined) and age group (0-4, 5-14 years), and also by sex for 15-59 years. From total deaths by broad age group and sex from 1999 and 2009 census analyses, community deaths were estimated by deduction of hospital deaths MC. National proportional mortality by cause was estimated by a weighted average of MC and CHF deaths. National estimates indicate main causes of deaths <5 years were: perinatal disorders (45 %) and malaria, diarrhea, and pneumonia (27 %). For 15-59 years, main causes of male deaths were: circulatory disease 27 %, neoplasms 13 %, injury 13 %, liver disease 10 %, infection 10 %, diabetes 7 %, and chronic respiratory disease 7 %; and for females: neoplasms 29 %, circulatory disease 15 %, diabetes 10 %, infection 9 %, and maternal deaths 8 %. Infection included tuberculosis, malaria, and viral hepatitis. Liver disease (including hepatitis and cancer) accounted for 18 % of deaths in adult males and 9 % in females. Non-communicable disease (NCD), including circulatory disease, diabetes, neoplasm, and chronic respiratory disease, accounted for 52 % of premature deaths in adult

Understanding how lay people perceive the causes of mortality and their associated risk factors is important for public health. In resource-limited settings, where verbal autopsy (VA) is used as the most expedient method of determining cause of death, it is important to understand how pre-existing concepts of cause of death among VA-informants may influence their VA-responses and the consequential impact on cause of death assessment. This study describes the agreement between VA-derived causes of death and informant-perceived causes and associated influential factors, which also reflects lay health literacy in this setting. Using 20 years of VA data (n=11,228) from the Agincourt Health and Demographic Surveillance System (HDSS) site in rural South Africa, we explored the agreement between the causes of death perceived by the VA-informants and those assigned by the automated Inter-VA tool. Kappa statistics and concordance correlation coefficients were applied to measure agreement at individual and population levels, respectively. Multivariable regression models were used to explore factors associated with recognised lay perceptions of causes of mortality. Agreement between informant-perceived and VA-derived causes of death at the individual level was limited, but varied substantially by cause of death. However, agreement at the population level, comparing cause-specific mortality fractions was higher, with the notable exception of bewitchment as a cause. More recent deaths, those in adults aged 15-49 years, deaths outside the home, and those associated with external causes showed higher concordance with InterVA. Overall, informant perception of causes of death was limited, but depended on informant characteristics and causes of death, and to some extent involved non-biomedical constructs. Understanding discordance between perceived and recognised causes of death is important for public health planning; low community understanding of causes of death may be

Landslides - Cause and effect

Radbruch-Hall, D. H.; Varnes, D.J.

Landslides can cause seismic disturbances; landslides can also result from seismic disturbances, and earthquake-induced slides have caused loss of life in many countries. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides. Slope movement in general is a major process of the geologic environment that places constraints on engineering development. In order to understand and foresee both the causes and effects of slope movement, studies must be made on a regional scale, at individual sites, and in the laboratory. Areal studies - some embracing entire countries - have shown that certain geologic conditions on slopes facilitate landsliding; these conditions include intensely sheared rocks; poorly consolidated, fine-grained clastic rocks; hard fractured rocks underlain by less resistant rocks; or loose accumulations of fine-grained surface debris. Field investigations as well as mathematical- and physical-model studies are increasing our understanding of the mechanism of slope movement in fractured rock, and assist in arriving at practical solutions to landslide problems related to all kinds of land development for human use. Progressive failure of slopes has been studied in both soil and rock mechanics. New procedures have been developed to evaluate earthquake response of embankments and slopes. The finite element method of analysis is being extensively used in the calculation of slope stability in rock broken by joints, faults, and other discontinuities. ?? 1976 International Association of Engineering Geology.

Scedosporium spp. are increasingly recognized as causes of resistant life-threatening infections in immunocompromised patients. Scedosporium spp. also cause a wide spectrum of conditions, including mycetoma, saprobic involvement and colonization of the airways, sinopulmonary infections, extrapulmonary localized infections, and disseminated infections. Invasive scedosporium infections are also associated with central nervous infection following near-drowning accidents. The most common sites of infection are the lungs, sinuses, bones, joints, eyes, and brain. Scedosporium apiospermum and Scedosporium prolificans are the two principal medically important species of this genus. Pseudallescheria boydii, the teleomorph of S. apiospermum, is recognized by the presence of cleistothecia. Recent advances in molecular taxonomy have advanced the understanding of the genus Scedosporium and have demonstrated a wider range of species than heretofore recognized. Studies of the pathogenesis of and immune response to Scedosporium spp. underscore the importance of innate host defenses in protection against these organisms. Microbiological diagnosis of Scedosporium spp. currently depends upon culture and morphological characterization. Molecular tools for clinical microbiological detection of Scedosporium spp. are currently investigational. Infections caused by S. apiospermum and P. boydii in patients and animals may respond to antifungal triazoles. By comparison, infections caused by S. prolificans seldom respond to medical therapy alone. Surgery and reversal of immunosuppression may be the only effective therapeutic options for infections caused by S. prolificans. PMID:18202441

Tetanus is a bacterial infection caused by Clostridium tetani and most commonly presents as trismus or other muscle spasms. Despite the development of the tetanus toxoid vaccine, tetanus infection has not been eradicated. Additionally, while there are hypothesized protective levels of tetanus antibody, tetanus infection may still occur in properly vaccinated individuals. We report the case of a 31-year-old male that presented to the emergency department (ED) with a 2-day history of neck and jaw pain. He reports puncturing his hand with a rusty nail 10 days prior. His reported vaccination history was that he received his last booster vaccination 13 years prior to presentation. In the ED, tetanus vaccine, tetanus immune globulin, and metronidazole were administered. His symptoms improved over the next 2 days and resolved at day 6. Despite his presentation of tetanus infection and rule out of other causes for his symptoms, his tetanus antibody level was reported at 8.4 U/mL, which is considered to be protective.A tetanus antibody level that is adequate for protective immunity should not preclude a patient from treatment of tetanus infection. This case demonstrates that a thorough history, physical exam, and rule out of other causes should guide treatment when there is concern for a tetanus infection.

Autistic spectrum disorder: evaluating a possible contributing or causal role of epilepsy.

Deonna, Thierry; Roulet, Eliane

The onset of epilepsy in brain systems involved in social communication and/or recognition of emotions can occasionally be the cause of autistic symptoms or may aggravate preexisting autistic symptoms. Knowing that cognitive and/or behavioral abnormalities can be the presenting and sometimes the only symptom of an epileptic disorder or can even be caused by paroxysmal EEG abnormalities without recognized seizures, the possibility that this may apply to autism has given rise to much debate. Epilepsy and/or epileptic EEG abnormalities are frequently associated with autistic disorders in children but this does not necessarily imply that they are the cause; great caution needs to be exercised before drawing any such conclusions. So far, there is no evidence that typical autism can be attributed to an epileptic disorder, even in those children with a history of regression after normal early development. Nevertheless, there are several early epilepsies (late infantile spasms, partial complex epilepsies, epilepsies with CSWS, early forms of Landau-Kleffner syndrome) and with different etiologies (tuberous sclerosis is an important model of these situations) in which a direct relationship between epilepsy and some features of autism may be suspected. In young children who primarily have language regression (and who may have autistic features) without evident cause, and in whom paroxysmal focal EEG abnormalities are also found, the possible direct role of epilepsy can only be evaluated in longitudinal studies.

Inherited and Uncommon Causes of Stroke.

PubMed

Majersik, Jennifer Juhl

2017-02-01

This article is a practical guide to identifying uncommon causes of stroke and offers guidance for evaluation and management, even when large controlled trials are lacking in these rarer forms of stroke. Fabry disease causes early-onset stroke, particularly of the vertebrobasilar system; enzyme replacement therapy should be considered in affected patients. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), often misdiagnosed as multiple sclerosis, causes migraines, early-onset lacunar strokes, and dementia. Moyamoya disease can cause either ischemic or hemorrhagic stroke; revascularization is recommended in some patients. Cerebral amyloid angiopathy causes both microhemorrhages and macrohemorrhages, resulting in typical stroke symptoms and progressive dementia. Pregnancy raises the risk of both ischemic and hemorrhagic stroke, particularly in women with preeclampsia/eclampsia. Pregnant women are also at risk for posterior reversible encephalopathy syndrome (PRES), reversible cerebral vasoconstriction syndrome, and cerebral venous sinus thrombosis. Experts recommend that pregnant women with acute ischemic stroke not be systematically denied the potential benefits of IV recombinant tissue plasminogen activator. Neurologists should become familiar with these uncommon causes of stroke to provide future risk assessment and family counseling and to implement appropriate treatment plans to prevent recurrence.

Mortality from violent causes in the Americas.

Yunes, J

1993-01-01

This article provides an assessment of 1986 mortality from violent causes in the Americas. Directed at assisting with development of preventive public health measures, it employs data available in the PAHO data base to focus on the under-25 year age group, compare mortality from violent causes with mortality from infectious and parasitic diseases, and evaluate the relative role of motor vehicle traffic accidents, other accidents, suicide, homicide, and deaths from unknown causes in mortality from violent causes. The study uses the classification of causes presented in the International Classification of Diseases, Ninth Revision. The results show that 517,465 deaths from violent causes were registered in 28 countries and political units of the Americas in 1986, mortality from these causes ranging from 19.3 deaths per 100,000 inhabitants in Jamaica to 125 in El Salvador. Examination of available 1980-1986 data from five countries points to steady increases in mortality from violent causes in Brazil and Cuba that began respectively in 1983 and 1984. Assessment of male and female 1986 mortality from these causes in nine countries showed male mortality to be substantially higher, the lowest male:female ratio (in Cuba) being 1.9:1. Among infants, infectious and parasitic disease mortality was greater than mortality from violent causes in most countries. However, from age 1 to the study's 25-year cutoff, mortality from violent causes was found to exceed infectious and parasitic disease mortality in most countries and to play an especially large role in deaths among those 19-24 years old. Data from eight countries suggested that accidents other than motor vehicle traffic accidents were accounting for much of the mortality from violent causes among infants and the 1-4 year age group in 1986, while motor vehicle traffic accidents rivaled other accidents in importance among the older (5-9, 10-14, 15-19, and 19-24) age groups. It appears that the information presented could

Blindness caused by cosmetic filler injection: a review of cause and therapy.

Vascular occlusion causing blindness is a rare yet greatly feared complication of the use of facial aesthetic fillers. The authors performed a review of the aesthetic literature to ascertain the reported cases of blindness and the literature reporting variations in the vascular anatomy of the human face. The authors suggest a small but potentially helpful addition to the accepted management of the acute case. Cases of blindness, mostly irreversible, from aesthetic filler injections have been reported from Asia, Europe, and North America. Autologous fat appears to be the most frequent filler causing blindness. Some cases of partial visual recovery have been reported with hyaluronic acid and calcium hydroxylapatite fillers. The sudden profusion of new medical and nonmedical aesthetic filler injectors raises a new cause for alarm about patient safety. The published reports in the medical literature are made by experienced aesthetic surgeons and thus the actual incidence may be even higher. Also, newer injectors may not be aware of the variations in the pattern of facial vascular arborization. The authors present a summary of the relevant literature to date and a suggested helpful addition to the protocols for urgent management.

Central causes of hypogonadism--functional and organic.

PubMed

Warren, Michelle P; Vu, Caroline

2003-09-01

Whether caused by environmental factors, lesions, genetic mutations, drug interactions, or unknown origins, the path of the central causes of hypogonadism frequently leads back to the GnRH pulse generator. In some cases, the cause can be unequivocally traced to a single factor, such as some of the congenital syndromes previously described. In most instances, however, hypogonadism is occult or functional. Because of the wide spectrum and complexity of underlying causes, a definitive diagnosis, especially in functional causes of the disorder, is not always attainable.

Oculo-auriculo-vertebral spectrum is a complex developmental disorder characterised mainly by anomalies of the ear, hemifacial microsomia, epibulbar dermoids and vertebral anomalies. The aetiology is largely unknown, and the epidemiological data are limited and inconsistent. We present the largest population-based epidemiological study to date, using data provided by the large network of congenital anomalies registries in Europe. The study population included infants diagnosed with oculo-auriculo-vertebral spectrum during the 1990–2009 period from 34 registries active in 16 European countries. Of the 355 infants diagnosed with oculo-auriculo-vertebral spectrum, there were 95.8% (340/355) live born, 0.8% (3/355) fetal deaths, 3.4% (12/355) terminations of pregnancy for fetal anomaly and 1.5% (5/340) neonatal deaths. In 18.9%, there was prenatal detection of anomaly/anomalies associated with oculo-auriculo-vertebral spectrum, 69.7% were diagnosed at birth, 3.9% in the first week of life and 6.1% within 1 year of life. Microtia (88.8%), hemifacial microsomia (49.0%) and ear tags (44.4%) were the most frequent anomalies, followed by atresia/stenosis of external auditory canal (25.1%), diverse vertebral (24.3%) and eye (24.3%) anomalies. There was a high rate (69.5%) of associated anomalies of other organs/systems. The most common were congenital heart defects present in 27.8% of patients. The prevalence of oculo-auriculo-vertebral spectrum, defined as microtia/ear anomalies and at least one major characteristic anomaly, was 3.8 per 100 000 births. Twinning, assisted reproductive techniques and maternal pre-pregnancy diabetes were confirmed as risk factors. The high rate of different associated anomalies points to the need of performing an early ultrasound screening in all infants born with this disorder. PMID:24398798

Diagnosis of reversible causes of coma.

PubMed

Edlow, Jonathan A; Rabinstein, Alejandro; Traub, Stephen J; Wijdicks, Eelco F M

2014-12-06

Because coma has many causes, physicians must develop a structured, algorithmic approach to diagnose and treat reversible causes rapidly. The three main mechanisms of coma are structural brain lesions, diffuse neuronal dysfunction, and, rarely, psychiatric causes. The first priority is to stabilise the patient by treatment of life-threatening conditions, then to use the history, physical examination, and laboratory findings to identify structural causes and diagnose treatable disorders. Some patients have a clear diagnosis. In those who do not, the first decision is whether brain imaging is needed. Imaging should be done in post-traumatic coma or when structural brain lesions are probable or possible causes. Patients who do not undergo imaging should be reassessed regularly. If CT is non-diagnostic, a checklist should be used use to indicate whether advanced imaging is needed or evidence is present of a treatable poisoning or infection, seizures including non-convulsive status epilepticus, endocrinopathy, or thiamine deficiency.

Stroke patients with hemiplegia exhibit flexor spasms in the upper limb and extensor spasms in the lower limb, and their movement patterns vary greatly. Constraint-induced movement therapy is an upper limb rehabilitation technique used in stroke patients with hemiplegia; however, studies of lower extremity rehabilitation are scarce. In this study, stroke patients with lower limb hemiplegia underwent conventional Bobath therapy for 4 weeks as baseline treatment, followed by constraint-induced movement therapy for an additional 4 weeks. The 10-m maximum walking speed and Berg balance scale scores significantly improved following treatment, and lower extremity motor function also improved. The results of functional MRI showed that constraint-induced movement therapy alleviates the reduction in cerebral functional activation in patients, which indicates activation of functional brain regions and a significant increase in cerebral blood perfusion. These results demonstrate that constraint-induced movement therapy promotes brain functional reorganization in stroke patients with lower limb hemiplegia. PMID:25337108

Inorganic arsenic causes fatty liver and interacts with ethanol to cause alcoholic liver disease in zebrafish

2018-01-01

ABSTRACT The rapid increase in fatty liver disease (FLD) incidence is attributed largely to genetic and lifestyle factors; however, environmental toxicants are a frequently overlooked factor that can modify the effects of more common causes of FLD. Chronic exposure to inorganic arsenic (iAs) is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combinatorial interaction with other disease-causing factors has been fully investigated. Here, we examined the contribution of iAs to FLD using zebrafish and tested the interaction with ethanol to cause alcoholic liver disease (ALD). We report that zebrafish exposed to iAs throughout development developed specific phenotypes beginning at 4 days post-fertilization (dpf), including the development of FLD in over 50% of larvae by 5 dpf. Comparative transcriptomic analysis of livers from larvae exposed to either iAs or ethanol revealed the oxidative stress response and the unfolded protein response (UPR) caused by endoplasmic reticulum (ER) stress as common pathways in both these models of FLD, suggesting that they target similar cellular processes. This was confirmed by our finding that arsenic is synthetically lethal with both ethanol and a well-characterized ER-stress-inducing agent (tunicamycin), suggesting that these exposures work together through UPR activation to cause iAs toxicity. Most significantly, combined exposure to sub-toxic concentrations of iAs and ethanol potentiated the expression of UPR-associated genes, cooperated to induce FLD, reduced the expression of as3mt, which encodes an arsenic-metabolizing enzyme, and significantly increased the concentration of iAs in the liver. This demonstrates that iAs exposure is sufficient to cause FLD and that low doses of iAs can potentiate the effects of ethanol to cause liver disease. This article has an associated First Person interview with the first author of the paper. PMID:29361514

Common Cause Failure Modes

2011-01-01

High technology industries with high failure costs commonly use redundancy as a means to reduce risk. Redundant systems, whether similar or dissimilar, are susceptible to Common Cause Failures (CCF). CCF is not always considered in the design effort and, therefore, can be a major threat to success. There are several aspects to CCF which must be understood to perform an analysis which will find hidden issues that may negate redundancy. This paper will provide definition, types, a list of possible causes and some examples of CCF. Requirements and designs from NASA projects will be used in the paper as examples.

Forty to eighty percent of the patients with accessory pathways (APs) manifest themselves by tachyarrhythmias. Many of these patients needed either life-long medical therapy or surgery. In order to avoid the discomfort and expenses in surgical procedures, closed chest percutaneous catheter ablation of APs became a potentially desirable therapeutic approach. Many investigations indicated that ablation of right APs by transcatheter direct current (dc) shock could cause life-threatening arrhythmias, right coronary arterical (RCA) spasm, etc. With the development of transcatheter laser technique, it has been used in drug-incurable arrhythmias. The results show that laser ablation is much safer than surgery and electric shock therapy. The purpose of this study is to explore the effectiveness, advantages, and complications with transcatheter Nd:YAG laser and dc shock in the ablation of right atrioventricular accessory pathways in the atrium near the tricuspid annulus (TA) in 20 dogs.

Telomerase counteracts telomere shortening, preventing cellular senescence. Telomerase deficiency causes telomere syndromes because of premature telomere exhaustion in highly proliferative cells. Paradoxically, in a recent issue of Cell, Margalef et al. (2018) demonstrate that telomerase causes telomere loss in cells lacking the RTEL1 helicase, which is defective in Hoyeraal-Hreidarsson syndrome (HHS). Copyright © 2018 Elsevier Inc.

Periocular necrotizing fasciitis is a rare but potentially devastating disease, accompanied by high rates of morbidity and mortality. We report 5 cases of periocular necrotizing fasciitis resulting in severe vision loss, 3 of which required exenteration to contain the disease and only 1 of which recovered vision. Three cases were caused by group A streptococcus; 1, by methicillin-resistant Staphylococcus aureus; and 1, by Streptococcus anginosus constellatus. Providers should maintain a high clinical suspicion for necrotizing fasciitis and distinguish it from more common forms of cellulitis. As seen in these 5 cases, periocular necrotizing fasciitis may cause severe visual loss more often than previously recognized. To our knowledge, this is also the first report of Streptococcus anginosus constellatus causing necrotizing fasciitis.

All-Cause and Cause-Specific Mortality Associated with Bariatric Surgery: A Review.

PubMed

Adams, Ted D; Mehta, Tapan S; Davidson, Lance E; Hunt, Steven C

2015-12-01

The question of whether or not nonsurgical intentional or voluntary weight loss results in reduced mortality has been equivocal, with long-term mortality following weight loss being reported as increased, decreased, and not changed. In part, inconsistent results have been attributed to the uncertainty of whether the intentionality of weight loss is accurately reported in large population studies and also that achieving significant and sustained voluntary weight loss in large intervention trials is extremely difficult. Bariatric surgery has generally been free of these conflicts. Patients voluntarily undergo surgery and the resulting weight is typically significant and sustained. These elements, combined with possible non-weight loss-related mechanisms, have resulted in improved comorbidities, which likely contribute to a reduction in long-term mortality. This paper reviews the association between bariatric surgery and long-term mortality. From these studies, the general consensus is that bariatric surgical patients have: 1) significantly reduced long-term all-cause mortality when compared to severely obese non-bariatric surgical control groups; 2) greater mortality when compared to the general population, with the exception of one study; 3) reduced cardiovascular-, stroke-, and cancer-caused mortality when compared to severely obese non-operated controls; and 4) increased risk for externally caused death such as suicide.

Facial nerve palsy (FNP) occurs less frequently in children as compared to adults but most cases are secondary to an identifiable cause. These children may have a variety of ocular and systemic features associated with the palsy and need detailed ophthalmic and systemic evaluation. This was a retrospective chart review of all the cases of FNP below the age of 16 years, presenting to a tertiary ophthalmic hospital over the period of 9 years, from January 2000 to December 2008. A total of 22 patients were included in the study. The average age at presentation was 6.08 years (range, 4 months to 16 years). Only one patient (4.54%) had bilateral FNP and 21 cases (95.45%) had unilateral FNP. Seventeen patients (77.27%) had congenital palsy and of these, five patients had a syndromic association, three had birth trauma and nine patients had idiopathic palsy. Five patients (22.72%) had an acquired palsy, of these, two had a traumatic cause and one patient each had neoplastic origin of the palsy, iatrogenic palsy after surgery for hemangioma and idiopathic palsy. Three patients had ipsilateral sixth nerve palsy, two children were diagnosed to have Moebius syndrome, one child had an ipsilateral Duane's syndrome with ipsilateral hearing loss. Corneal involvement was seen in eight patients (36.36%). Amblyopia was seen in ten patients (45.45%). Neuroimaging studies showed evidence of trauma, posterior fossa cysts, pontine gliosis and neoplasms such as a chloroma. Systemic associations included hemifacial macrosomia, oculovertebral malformations, Dandy Walker syndrome, Moebius syndrome and cerebral palsy FNP in children can have a number of underlying causes, some of which may be life threatening. It can also result in serious ocular complications including corneal perforation and severe amblyopia. These children require a multifaceted approach to their care.
