Static suspension using fascia lata graft is used as a reconstructive procedure against drooping of the mouth corner for treating longstanding facial paralysis. Although it achieves symmetry at rest, movement of the mouth corner at mouth opening is restricted to some extent because it is fixed with fascia lata to the immovable temporal fascia, the parotid fascia, or bones. This was overcome by suspending the mouth corner to the mandibular coronoid process with fascia lata, which enabled a shift of the mouth corner with mouth opening and closure. The nine patients discussed in this study were operated on since 1994 for longstanding facial paralysis and followed-up for over 1.5 years. As in conventional static suspension, the fascia lata was harvested and split into two bands. Next, one semi-oval fascial loop was inserted around the paralysed part of the mouth and tied with another fascial band at the mouth corner, which was looped to the mandibular coronoid process. The suspended fascia lata graft was relaxed with anteroinferior movement of the coronoid process at mouth opening, enabling the mouth corner to shift inferiorly. The mouth corner returned to its original position at mouth closure, and the nasolabial fold deepened during mastication. No limitation in mouth opening was observed. Suspension of the mouth corner to the mandibular coronoid process provided a dynamic element, thereby restoring a near-normal shift. The procedure is considered as an alternative for reconstructing the malar region of patients with facial paralysis and in whom dynamic reconstruction is not indicated.

We report the virological and clinical features of 8 children who presented with adenovirus-associated acute flaccid paralysis (AFP) during an epidemic of enterovirus type 71 (EV71)-associated hand-foot-and-mouth disease (HFMD) in Sarawak, Malaysia, in 1997. Neutralization tests and phylogenetic analysis revealed adenovirus type 21 (Ad21), although DNA restriction digests suggested that this virus was different from the prototype Ad21. Four children had upper-limb monoparesis, 2 had lower-limb monoparesis (one of whom had changes in the anterior spinal cord noted on magnetic resonance imaging), and 2 had flaccid paraparesis. At follow-up, 4 children were noted to have made full recoveries and 3 had residual flaccid weakness and wasting. Neurophysiological investigation revealed a mixture of axonal and demyelinating features in motor and sensory nerves, with denervation. These findings suggest that Ad21 might cause AFP by anterior horn cell damage or neuropathy of the brachial or lumbosacral plexus. The occurrence of these unusual adenovirus infections during an outbreak of EV71-associated HFMD suggests that an interaction between the 2 viruses may have occurred.

To determine whether repeated CHO mouth rinsing would improve neuromuscular performance during high intensity fatiguing contractions. 18 young men (26.1±5.0 yr; 22.9±1,9 BMI) performed 3 maximal voluntary isometric contractions (MVICPRE). Immediately after, they completed 10 s mouth rinse with either 6.4% maltodextrine solution [MAL] or 7.1% glucose solution [GLU] or water [W] or artificially sweetened solution [PLA] or a control trial with no rinse [CON] in a cross over protocol. 5 sets of 30 isokinetic fatiguing contractions at 180°s(-1) and a MVICPOST with their elbow flexors were performed after each mouth rinse. Mechanical and electromyographic signals (EMG) were recorded from the biceps brachii muscle and parameters of interest analyzed. 1) When rinsing the mouth with a solution containing CHO, independently of the sweetness, isokinetic performance was enhanced as shown by the greater total work achieved in comparison with CON; 2) the decay of torque and mean fiber conduction velocity (MFCV) recorded at the end of the fatiguing task was lower when rinsing the mouth with GLU compared to CON; 3) the torque recorded during the MVICPOST was greater with CHO with respect to CON and this was associated to a lower decay of MFCV. CHO mouth rinse counteracts the fatigue-induced decline in neuromuscular performance, supporting the notion that CHO rinse may activate positive afferent signals able to modify the motor output. Repeated mouth rinsing with sweet and non-sweet CHO-containing solutions can improve neuromuscular performance during an isokinetic intermittent fatiguing task.
It is well known that carbohydrate (CHO) supplementation can improve performance in endurance exercises through several mechanisms such as maintenance of glycemia and sparing endogenous glycogen as well as the possibility of a central nervous-system action. Some studies have emerged in recent years in order to test the hypothesis of ergogenic action via central nervous system. Recent studies have demonstrated that CHO mouth rinse can lead to improved performance of cyclists, and this may be associated with the activation of brain areas linked to motivation and reward. These findings have already been replicated in other endurance modalities, such as running. This alternative seems to be an attractive nutritional tool to improve endurance exercise performance.

Oral carbohydrate (CHO) rinsing has been demonstrated to provide beneficial effects on exercise performance of durations of up to one hour. The aim of the present study was to investigate the effects of CHO mouth rinsing on morning high-intensity exercise performance. Following institutional ethical approval and familiarisation, 12 healthy males (mean ± SD age: 23 ± 3 years, height: 175.5 ± 7.4 cm, body mass: 75.4 ± 7.5 kg) participated in this study. Countermovement jump (CMJ) height, isometric mid-thigh pull peak force, 10 m sprint time and bench press and back squat repetitions to failure were assessed following CHO and placebo (PLA) rinsing or a control condition (CON). All testing took place at 07:30 following an 11 hour overnight fast. Performance of CMJ height (CHO: 39 ± 7 cm; PLA: 38 ± 7 cm; CON: 36 ± 6 cm; P = .003, [Formula: see text] = 0.40), 10 m sprint time (CHO: 1.78 ± 0.07 s; PLA: 1.81 ± 0.07 s; CON: 1.85 ± 0.05 s; P = .001, [Formula: see text] = 0.47), the number of bench press (CHO: 25 ± 3; PLA: 24 ± 4; CON: 22 ± 4; P < .001, [Formula: see text] = 0.55) and squat (CHO: 31 ± 4; PLA: 29 ± 5; CON: 26 ± 6; P < .001, [Formula: see text] = 0.70) repetitions and mean felt arousal (CHO: 5 ± 1; PLA: 4 ± 0; CON: 4 ± 0; P = .009, [Formula: see text] = 0.25) improved following CHO rinsing. However, isometric mid-thigh pull peak force was unchanged (CHO: 2262 ± 288 N; PLA: 2236 ± 354 N; CON: 2212 ± 321 N; P = .368, [Formula: see text] = 0.08). These results suggest that oral CHO rinsing solution significantly improved the morning performance of CMJ height, 10 m sprint times, bench press and squat repetitions to failure and felt arousal, although peak force during an isometric mid-thigh pull, rating of perceived exertion and heart rate were unaffected.

Healthcare providers and lay people alike tend to form inaccurate first impressions of people with facial movement disorders such as facial paralysis (FP) because of the natural tendency to base impressions on the face. This study tested the effectiveness of the first interpersonal sensitivity training for FP. Undergraduate participants were randomly assigned to one of two training conditions or an untrained control. Education raised awareness about FP symptoms and experiences and instructed participants to form their impressions based on cues from the body and voice rather than the face. Education+feedback added feedback about the correctness of participants' judgments. Subsequently, participants watched 30s video clips of people with FP and rated their extraversion. Participants' bias and accuracy in the two training conditions did not significantly differ, but they were significantly less biased than controls. Training did not improve the more challenging task of accurately detecting individual differences in extraversion. Educating people improves bias, but not accuracy, of impressions of people with FP. Information from the education condition could be delivered in a pamphlet to those likely to interact with this population such as healthcare providers and educators.

To observe the effect of balanced muscular tension needling method for improving disabled function of stroke patients with spastic paralysis. One hundred and six cases with spastic paralysis were randomly divided into an observation group (54 cases) with balanced muscular tension needling method and a control group (52 cases) with routine acupuncture method. The observation group was treated by acupuncture at the side of extensor and flexor of limbs; while the control group was treated by acupuncture at Jianyu (LI 15), Quchi (LI 11), Waiguan (TE 5) etc. And the change of muscle strength, muscle tonus, muscle spasticity and range of joint motion were evaluated hefore and after treatment. After 30 days of treatment, the total effective rate of 96.3% (52/54) in the observation group was superior to that of 84.6% (44/32) in the control group (P < 0.01). After treatment muscle strength, muscle tonus, muscle spasticity and range of joint motion were improved in the two groups, hut the observation group was superior to the control group (all P < 0.05). Balanced muscular tension needling method can significantly improve the muscle strength, muscle tonus, muscle spasticity and the range of joint motion of the stroke patients with spastic paralysis.

Facial paralysis can contribute to disfigurement, psychological difficulties, and an inability to convey emotion via facial expression. In patients unable to perform a meaningful smile, free gracilis muscle transfer (FGMT) can often restore smile function. However, little is known about the impact on disease-specific quality of life. To determine quantitatively whether FGMT improves quality of life in patients with facial paralysis. Prospective evaluation of 154 FGMTs performed at a facial nerve center on 148 patients with facial paralysis. The Facial Clinimetric Evaluation (FaCE) survey and Facial Assessment by Computer Evaluation software (FACE-gram) were used to quantify quality-of-life improvement, oral commissure excursion, and symmetry with smile. Free gracilis muscle transfer. Change in FaCE score, oral commissure excursion, and symmetry with smile. There were 127 successful FGMTs on 124 patients and 14 failed procedures on 13 patients. Mean (SD) FaCE score increased significantly after successful FGMT (42.30 [15.9] vs 58.5 [17.60]; paired 2-tailed t test, P < .001). Mean (SD) FACE scores improved significantly in all subgroups (nonflaccid cohort, 37.8 [19.9] vs 52.9 [19.3]; P = .02; flaccid cohort, 43.1 [15.1] vs 59.6 [17.2]; P < .001; trigeminal innervation cohort, 38.9 [14.6] vs 55.2 [18.2]; P < .001; cross-face nerve graft cohort, 47.3 [16.6] vs 61.7 [16.9]; P < .001) except the failure cohort (36.5 [20.8] vs 33.5 [17.9]; Wilcoxon signed-rank test, P = .15). Analysis of 40 patients' photographs revealed a mean (SD) preoperative and postoperative excursion on the affected side of -0.88 (3.79) and 7.68 (3.38), respectively (P < .001); symmetry with smile improved from a mean (SD) of 13.8 (7.46) to 4.88 (3.47) (P < .001). Free gracilis muscle transfer has become a mainstay in the management armamentarium for patients with severe reduction in oral commissure movement after facial nerve insult and recovery. We found a

The Facial Grading Scale (FGS) is a quantitative instrument used to evaluate facial function after facial nerve injury. However, quantitative improvements in function after facial rehabilitation in people with chronic facial paralysis have not been shown. The objectives of this study were to use the FGS in a large series of consecutive subjects with facial paralysis to quantitatively evaluate improvements in facial function after facial nerve rehabilitation and to describe the management of chronic facial paralysis. The study was a retrospective review. A total of 303 individuals with facial paralysis were evaluated by 1 physical therapist at a tertiary care facial nerve center during a 5-year period. Facial rehabilitation included education, neuromuscular training, massage, meditation-relaxation, and an individualized home program. After 2 months of home exercises, the participants were re-evaluated, and the home program was tailored as necessary. All participants were evaluated with the FGS before the initiation of facial rehabilitation, and 160 participants were re-evaluated after receiving treatment. All participants underwent the initial evaluation at least 4 months after the onset of facial paralysis; for 49 participants, the evaluation took place more than 3 years after onset. Statistically significant increases in FGS scores were seen after treatment (P<.001, t test). The average initial score was 56 (SD=21, range=13-98), and the average score after treatment was 70 (SD=18, range=25-100). A limitation of this study was that evaluations were performed by only 1 therapist. For 160 patients with facial paralysis, statistically significant improvements after facial rehabilitation were shown; the improvements appeared to be long lasting with continued treatment. The improvements in the FGS scores indicated that patients can successfully manage symptoms with rehabilitation and underscored the importance of specialized therapy in the management of facial paralysis.

The objectives of this study are to describe central nervous system modulation associated with voice improvement following Type I thyroplasty in a patient with glottic insufficiency secondary to unilateral vocal fold paralysis. Serial functional magnetic resonance imaging scans were performed before as well as one and six months after thyroplasty. Paradigms consisting of four voice production tasks and a motor control task were completed. Volumes of activation within regions activated during each task were measured. Acoustic and aerodynamic measures were also obtained. A widespread network of neural activations was shown for all tasks. Differences in volumes of activation 1-month postsurgery positively correlated with acoustic and aerodynamic improvements. Sixth months following medialization, lesser volumes of activation were observed in all regions. Prior to this session, however, the patient's mediastinal disease progressed, leading to a significant deterioration in voice. Functional differences between patient brain maps yield new information about the central nervous system's ability to reorganize sensorimotor representations associated with voice improvement following Type I thyroplasty in a patient with glottic insufficiency secondary to unilateral vocal fold paralysis (UVFP).

High quality acute flaccid paralysis (AFP) surveillance is required to maintain polio-free status of a country. Papua New Guinea (PNG) is considered as one of the highest risk countries for polio re-importation and circulation in the Western Pacific Region (WPRO) of the World Health Organization due to poor healthcare infrastructure and inadequate performance in AFP surveillance. The Government of PNG, in collaboration with WHO, piloted the introduction of short-message-service (SMS) to sensitize pediatricians and provincial disease control officers on AFP and to receive notification of possible AFP cases to improve surveillance quality in PNG. Ninety six health care professionals were registered to receive SMS reminders to report any case of acute flaccid paralysis. Fourteen SMS messages were sent to each participant from September 2012 to November 2013. The number of reported AFP cases were compared before and after the introduction of SMS. Two hundred fifty three unique responses were received with an overall response rate of 21 %. More than 80 % of responses were reported within 3 days of sending the SMS. The number of reported AFP cases increased from 10 cases per year in 2009-2012 to 25 cases per year during the study period and correlated with provincial participation of the health care professionals. Combined with improved sensitization of health care professionals on AFP reporting criteria and sample collection, SMS messaging provides an effective means to increase timely reporting and improve the availability of epidemiologic information on polio surveillance in PNG.

Objectives: To determine whether site-specific mouth rinsing with oral disinfectants can improve oral odor beyond the traditional panoral mouth disinfection with mouth rinses by targeting specifically oral malodor implicated anaerobic bacteria Methods: Twenty healthy fasting subjects volunteered for a blinded prospective, descriptive correlational crossover cross-section clinical trial conducted during the month of Ramadan between July and August 2013 in Albaha province in Saudi Arabia involving the application of Listerine® Cool Mint® mouth rinse by either the traditional panoral rinsing method, or a site-specific disinfection method targeting the subgingival and supragingival plaque and the posterior third of the tongue dorsum, while avoiding the remaining locations within the oral cavity. The viable anaerobic and aerobic bacterial counts, volatile sulfur compounds (VSCs) levels, organoleptic assessment of oral odor, and the tongue-coating index were compared at baseline, one, 5, and 9 hours after the treatment. Results: The site-specific disinfection method reduced the VSCs and anaerobic bacterial loads while keeping the aerobic bacterial numbers higher than the traditional panoral rinsing method. Conclusion: Site-specific disinfection can more effectively maintain a healthy oral cavity by predominantly disinfecting the niches of anaerobic bacteria within the oral cavity. PMID:25399224

This study evaluates the influence of sniffing position combined with mouth opening on the effectiveness of facemask ventilation in paralyzed pediatric patients undergoing adenotonsillectomy during sevoflurane-N(2)O anesthesia. After Institutional Ethics Committee approval, 40 children 5-11 years of age who were scheduled for an elective adenotonsillectomy operation were enrolled in this prospective randomized study. After routine monitoring and pre-oxygenation, anesthesia was induced with sevoflurane 8% in a mixture of 50% N(2)O-O(2). Three minutes after the administration of vecuronium, the sequence of the positions was randomized. Three positions were applied during facemask ventilation: Position CN (closed mouth - neutral head and neck position), position CS (closed mouth-sniffing position) and position OS (opened mouth-sniffing position). Volume-controlled ventilation was started. Peak inspiratory pressure (PIP), tidal volume (V(T)), expired tidal volume (V(Texp)) and end-tidal CO(2) pressure were recorded. The percent of leakage was calculated. The primary endpoint of this study was the expired tidal volume (V(Texp)). There was a statistically significant difference among the three positions for V(Texp) and PIP values. The OS resulted in higher V(Texp) values when compared with CN (P=0.022). The OS was significantly better than the other two positions, resulting in lower PIP values (P<0.001 and P=0.004, for CN and CS, respectively). The OS also resulted in less leakage during facemask ventilation when compared with CN and CS. Sniffing position combined with mouth opening improves V(Texp) and PIP values during facemask ventilation during sevoflurane-N(2)O anesthesia in paralyzed pediatric patients with adenotonsillar hypertrophy.

We tested the hypothesis that carbohydrate mouth rinsing, alone or in combination with caffeine, augments high-intensity interval (HIT) running capacity undertaken in a carbohydrate-restricted state. Carbohydrate restriction was achieved by performing high-intensity running to volitional exhaustion in the evening prior to the main experimental trials and further refraining from carbohydrate intake in the post-exercise and overnight period. On the subsequent morning, eight males performed 45-min steady-state (SS) exercise (65% [Formula: see text]) followed by HIT running to exhaustion (1-min at 80% [Formula: see text]interspersed with 1-min walking at 6 km/h). Subjects completed 3 trials consisting of placebo capsules (administered immediately prior to SS and immediately before HIT) and placebo mouth rinse at 4-min intervals during HIT (PLACEBO), placebo capsules but 10% carbohydrate mouth rinse (CMR) at corresponding time-points or finally, caffeine capsules (200 mg per dose) plus 10% carbohydrate mouth rinse (CAFF + CMR) at corresponding time-points. Heart rate, capillary glucose, lactate, glycerol and NEFA were not different at exhaustion during HIT (P > 0.05). However, HIT capacity was different (P < 0.05) between all pair-wise comparisons such that CAFF + CMR (65 ± 26 min) was superior to CMR (52 ± 23 min) and PLACEBO (36 ± 22 min). We conclude that carbohydrate mouth rinsing and caffeine ingestion improves exercise capacity undertaken in carbohydrate-restricted states. Such nutritional strategies may be advantageous for those athletes who deliberately incorporate elements of training in carbohydrate-restricted states (i.e. the train-low paradigm) into their overall training programme in an attempt to strategically enhance mitochondrial adaptations of skeletal muscle.

Monodisperse aerosol deposition in an idealized mouth geometry with a relatively small inlet diameter (D (in) = 3.0 mm) was studied numerically using a standard Large Eddy Simulation (LES). A steady inhalation flow rate of Q = 32.2 L/min was used. Thousands of particles (2.5, 3.7, and 5.0 microm in diameter and rho (f) = 912.0 kg/m(3) density) were released separately in the computational domain and aerosol deposition was determined. The total aerosol deposition results in this idealized mouth were in relatively good agreement when compared with measured data obtained in separate experiments, showing considerable improvement over the standard RANS/EIM (Reynolds Averaged Navier-Stokes/Eddy Interaction Model) approach.

The purpose of this review was to identify studies that have investigated the effect of carbohydrate (CHO) mouth rinse on exercise performance, and to quantify the overall mean difference of this type of manipulation across the studies. The main mechanisms involving the potential benefit of CHO mouth rinse on performance was also explored. A systematic review was conducted in the following electronic databases: PubMed, SciELO, Science Direct, MEDLINE, and the Cochrane Library (Cochrane Central Register of Controlled Trials), without limit of searches. Eleven studies were classified as appropriate and their results were summarized and compared. In nine of them, CHO mouth rinse increased the performance (range from 1.50% to 11.59%) during moderate- to high-intensity exercise (~75% Wmax or 65% VO2max, ~1 h duration). A statistical analysis to quantify the individual and overall mean differences was performed in seven of the 11 eligible studies that reported power output (watts, W) as the main performance outcome. The overall mean difference was calculated using a random-effect model that accounts for true variation in effects occurring in each study, as well as random error within a single study. The overall effect of CHO mouth rinse on performance was significant (mean difference = 5.05 W, 95% CI 0.90 to 9.2 W, z = 2.39, p = 0.02) but there was a large heterogeneity between the studies (I2 = 52%). An activation of the oral receptors and consequently brain areas involved with reward (insula/operculum frontal, orbitofrontal cortex, and striatum) is suggested as a possible physiological mechanism responsible for the improved performance with CHO mouth rinse. However, this positive effect seems to be accentuated when muscle and liver glycogen stores are reduced, possibly due to a greater sensitivity of the oral receptors, and require further investigation.

Poor oral health, such as periodontal (gum) disease, has been found to be associated with an increased risk of adverse pregnancy outcomes including preterm birth, low birth weight, and neonatal and infant mortality, especially in low-and middle-income countries. However, there is little or no access to preventive dental care in most low-and middle-income countries. We propose to develop and test a "Mouth Rinse Intervention" among pregnant women to prevent the progression of periodontal disease during pregnancy and reduce adverse birth and neonatal outcomes in a rural county of China. This is a randomized controlled clinical trial. A sample of 468 (234 in each arm of the study) women in early pregnancy with periodontal disease will be recruited for the study. Periodontal disease will be diagnosed through the methods of Periodontal Screening and Recording. All women diagnosed with periodontal disease will be randomly allocated into the intervention or control group. Women assigned in the intervention group will be provided with non-alcohol antimicrobial mouth rinse containing cetylpyridinium chloride throughout the pregnancy and oral health education. Women in the control group will receive a package of tooth brush and paste, plus oral hygiene education. Women will be followed-up to childbirth until the 42nd day postpartum. The main outcomes include mean birthweight (gram) and mean gestational age (week). Compared with conventional mechanical 'scaling and root planning' periodontal treatment during pregnancy, our proposed mouth rinse intervention could be a simple, cost-effective, and sustainable solution to improve both mother's oral health and neonate outcomes. If the mouth rinse is confirmed to be effective, it would demonstrate great potential for the application in other low- or middle-income countries to prevent adverse birth outcomes such as preterm birth and low birth weight and to reduce neonatal and infant mortality. This trial was registered with Chinese

Acute Flaccid Paralysis (AFP) surveillance, including case investigation and specimen collection is a gold standard method for poliomyelitis surveillance. The expected annual non-polio AFP rate <15 years of age in Ireland is = 1/100 000 population. This study reviewed all cases of AFP reported to the Irish Paediatric Surveillance Unit and the Health Protection Surveillance Centre between January 2009 and December 2014 and compared reporting rates with the expected incidence rate annually. We assessed quality of surveillance data in terms of completeness of investigation for each case reported. Forty-three AFP cases in children <15 years were notified; 35 of which were confirmed. Guillain-Barre Syndrome (GBS) accounted for 48.6% (n=17) of AFP notifications. In 2014, the expected annual AFP target rate was reached. This study identified possible under-reporting of AFP paediatric cases in Ireland between 2009-2013. Completeness of investigations has improved over time, but requires further work.

In patients with hyperkalemic periodic paralysis (HyperKPP), attacks of muscle weakness or paralysis are triggered by K+ ingestion or rest after exercise. Force can be restored by muscle work or treatment with β2-adrenoceptor agonists. A missense substitution corresponding to a mutation in the skeletal muscle voltage-gated Na+ channel (Nav1.4, Met1592Val) causing human HyperKPP was targeted into the mouse SCN4A gene (mutants). In soleus muscles prepared from these mutant mice, twitch, tetanic force, and endurance were markedly reduced compared with soleus from wild type (WT), reflecting impaired excitability. In mutant soleus, contractility was considerably more sensitive than WT soleus to inhibition by elevated [K+]o. In resting mutant soleus, tetrodotoxin (TTX)-suppressible 22Na uptake and [Na+]i were increased by 470 and 58%, respectively, and membrane potential was depolarized (by 16 mV, P < 0.0001) and repolarized by TTX. Na+,K+ pump–mediated 86Rb uptake was 83% larger than in WT. Salbutamol stimulated 86Rb uptake and reduced [Na+]i both in mutant and WT soleus. Stimulating Na+,K+ pumps with salbutamol restored force in mutant soleus and extensor digitorum longus (EDL). Increasing [Na+]i with monensin also restored force in soleus. In soleus, EDL, and tibialis anterior muscles of mutant mice, the content of Na+,K+ pumps was 28, 62, and 33% higher than in WT, respectively, possibly reflecting the stimulating effect of elevated [Na+]i on the synthesis of Na+,K+ pumps. The results confirm that the functional disorders of skeletal muscles in HyperKPP are secondary to increased Na+ influx and show that contractility can be restored by acute stimulation of the Na+,K+ pumps. Calcitonin gene-related peptide (CGRP) restored force in mutant soleus but caused no detectable increase in 86Rb uptake. Repeated excitation and capsaicin also restored contractility, possibly because of the release of endogenous CGRP from nerve endings in the isolated muscles. These

Articles on acupuncture for peripheral facial paralysis were picked up from CNKI database. The retrieved original studies were evaluated and summarized. The problems of acupuncture for peripheral facial paralysis were analyzed, and concrete solutions were proposed. Problems that differential diagnosis, prognosis, treatment of severe facial paralysis, and identification of sequelae and compliation were not embasized in clinical treatment of facial paralysis. Consequently, the effectiveness of acupuncture for peripheral facial paralysis will be improved by sloving above problems.

Abstract Thoracic-surgery-related unilateral vocal fold paralysis (UVFP) may cause severe morbidity and can cause profound functional impairment and psychosocial stress in patients with pre-existing thoracic diseases. In-office intracordal hyaluronate (HA) injections have recently been applied to improve voice and quality of life in patients with vocal incompetence, but their effect on thoracic-surgery-related UVFP remains inconclusive. We therefore conducted a prospective study to clarify the effect of early HA injection on voice and quality of life in patients with thoracic-surgery-related UVFP. Patients with UVFP within 3 months after thoracic surgery who received office-based HA injection were recruited. Quantitative laryngeal electromyography, videolaryngostroboscopy, voice-related life quality (voice outcome survey), laboratory voice analysis, and health-related quality of life (SF-36) were evaluated at baseline, and at 1 month postinjection. A total of 104 consecutive patients accepted office-based HA intracordal injection during the study period, 34 of whom were treated in relation to thoracic surgery and were eligible for inclusion. Voice-related life quality, voice laboratory analysis, and most generic quality of life domains were significantly improved at 1 month after in-office HA intracordal injection. No HA-related complications were reported. Single office-based HA intracordal injection is a safe and effective treatment for thoracic-surgery-related UVFP, resulting in immediate improvements in patient quality of life, voice quality, and swallowing ability.

Determining the location of a sound source is crucial for survival. Both predators and prey usually produce sound while moving, revealing valuable information about their presence and location. Animals have thus evolved morphological and neural adaptations allowing precise sound localization. Mammals rely on the temporal and amplitude differences between the sound signals arriving at their two ears, as well as on the spectral cues available in the signal arriving at a single ear to localize a sound source. Most mammals rely on passive hearing and are thus limited by the acoustic characteristics of the emitted sound. Echolocating bats emit sound to perceive their environment. They can, therefore, affect the frequency spectrum of the echoes they must localize. The biosonar sound beam of a bat is directional, spreading different frequencies into different directions. Here, we analyse mathematically the spatial information that is provided by the beam and could be used to improve sound localization. We hypothesize how bats could improve sound localization by altering their echolocation signal design or by increasing their mouth gape (the size of the sound emitter) as they, indeed, do in nature. Finally, we also reveal a trade-off according to which increasing the echolocation signal's frequency improves the accuracy of sound localization but might result in undesired large localization errors under low signal-to-noise ratio conditions.

Neurovascular free muscle transfer is currently the mainstay for smile reconstruction. However, problems such as excessive muscle bulk and dislocation of the transferred muscle attachment have been described. Furthermore, dynamic movements of the transferred muscle are sometimes too strong or too weak, resulting in facial asymmetry. In these cases, secondary revisional operations for the transferred muscle are required after neurovascular free muscle transfer. This report describes revisional operative procedures in detail and examines the extent of improvement of the smile by comparing preoperative and postoperative results. Of 468 patients in whom neurovascular free muscle transfer was performed between 1977 and 2000, a total of 183 received revisional operations for the transferred muscle. Operations included revision of muscle attachment in 129 patients, debulking of the cheek in 114 patients, and fascia graft in 21 patients. Evaluation with the grading scale was performed in 117 of the 183 patients. Grading improved in 59 patients and worsened in seven patients. The remaining 51 patients displayed no change in grading. Differences between preoperative and post-operative grading were compared statistically, and revisional operations improved the grading score. Revisional operations are effective and important as secondary operations after neurovascular free muscle transfer. However, care must be taken not to damage the neurovascular pedicles.
Inactivated foot-and-mouth disease (FMD) vaccines are currently used worldwide. With the emergence of various FMD virus serotypes and subtypes, vaccines must become more suitable for field-based uses under the current circumstances in terms of the fast and proper selection of vaccine strains, an extended vaccine development period for new viruses, protecting against the risk of virus leakage during vaccine manufacture, counteracting the delayed onset of immune response, counteracting shorter durations of immunity, and the accurate serological differentiation of infected and vaccinated animals and multiple vaccination. The quality of vaccines should then be improved to effectively control FMD outbreaks and minimize the problems that can arise among livestock after vaccinations. Vaccine improvement should be based on using attenuated virus strains with high levels of safety. Moreover, when vaccines are urgently required for newly spread field strains, the seed viruses for new vaccines should be developed for only a short period. Improved vaccines should offer superior immunization to all susceptible animals including cattle and swine. In addition, they should have highly protective effects without persistent infection. In this way, if vaccines are developed using new methods such as reverse genetics or vector vaccine technology, in which live viruses can be easily made by replacing specific protective antigens, even a single vaccination is likely to generate highly protective effects with an extended duration of immunity, and the safety and stability of the vaccines will be assured. We therefore reviewed the current FMD vaccines and their adjuvants, and evaluated if they provide superior immunization to all susceptible animals including cattle and swine. PMID:23596585

To determine whether site-specific mouth rinsing with oral disinfectants can improve oral odor beyond the traditional panoral mouth disinfection with mouth rinses by targeting specifically oral malodor implicated anaerobic bacteria. Twenty healthy fasting subjects volunteered for a blinded prospective, descriptive correlational crossover cross-section clinical trial conducted during the month of Ramadan between July and August 2013 in Albaha province in Saudi Arabia involving the application of Listerine Cool Mint mouth rinse by either the traditional panoral rinsing method, or a site-specific disinfection method targeting the subgingival and supragingival plaque and the posterior third of the tongue dorsum, while avoiding the remaining locations within the oral cavity. The viable anaerobic and aerobic bacterial counts, volatile sulfur compounds (VSCs) levels, organoleptic assessment of oral odor, and the tongue-coating index were compared at baseline, one, 5, and 9 hours after the treatment. The site-specific disinfection method reduced the VSCs and anaerobic bacterial loads while keeping the aerobic bacterial numbers higher than the traditional panoral rinsing method. Site-specific disinfection can more effectively maintain a healthy oral cavity by predominantly disinfecting the niches of anaerobic bacteria within the oral cavity.

[Purpose] The motor paralysis-improving effect on the hemiplegic lower limb was compared among mirror therapy, integrated volitional-control electrical stimulation, therapeutic electrical stimulation, repetitive facilitative exercises, and the standard training method in post-stroke hemiplegia patients. [Subjects and Methods] Eighty one stroke patients admitted to a convalescent rehabilitation ward were randomly allocated to the above 5 treatment groups. Each patient performed functional training of the paralytic lower limb for 20 minutes a day for 4 weeks, and changes in the lower limb function were investigated using the Stroke Impairment Assessment Set. [Results] The hip and knee joint functions did not significantly improve in the standard training control group, but significant improvements were observed after 4 weeks in the other intervention groups. Significant improvement was noted in the ankle joint function in all groups. [Conclusion] Although the results were influenced by spontaneous recovery and the standard training in the control group, the hip and knee joints were more markedly improved by the interventions in the other 4 groups of patients with moderate paralysis, compared to the control group.

Facial paralysis can have devastating physical and psychosocial consequences. These are particularly severe in children in whom loss of emotional expressiveness can impair social development and integration. The etiologies of facial paralysis, prospects for spontaneous recovery, and functions requiring restoration differ in children as compared with adults. Here we review contemporary management of facial paralysis with a focus on special considerations for pediatric patients.

The dominant factor limiting the intrinsic spatial resolution of a positron emission tomography (PET) system is the size of the crystal elements in the detector. To increase sensitivity and achieve high spatial resolution, it is essential to use advanced depth-of-interaction (DOI) detectors and arrange them close to the subject. The DOI detectors help maintain high spatial resolution by mitigating the parallax error caused by the thickness of the scintillator near the peripheral regions of the field-of-view. As an optimal geometry for a brain PET scanner, with high sensitivity and spatial resolution, we proposed and developed the helmet-chin PET scanner using 54 four-layered DOI detectors consisting of a 16 × 16 × 4 array of GSOZ scintillator crystals with dimensions of 2.8 × 2.8 × 7.5 mm(3). All the detectors used in the helmet-chin PET scanner had the same spatial resolution. In this study, we conducted a feasibility study of a new add-on detector arrangement for the helmet PET scanner by replacing the chin detector with a segmented crystal cube, having high spatial resolution in all directions, which can be placed inside the mouth. The crystal cube (which we have named the mouth-insert detector) has an array of 20 × 20 × 20 LYSO crystal segments with dimensions of 1 × 1 × 1 mm(3). Thus, the scanner is formed by the combination of the helmet and mouth-insert detectors, and is referred to as the helmet-mouth-insert PET scanner. The results show that the helmet-mouth-insert PET scanner has comparable sensitivity and improved spatial resolution near the center of the hemisphere, compared to the helmet-chin PET scanner.

The carbohydrate (CHO) concentration of a mouth rinsing solution might influence the CHO sensing receptors in the mouth, with consequent activation of brain regions involved in reward, motivation and regulation of motor activity. The purpose of the present study was to examine the effects of maltodextrin mouth rinsing with different concentrations (3%, 6% and 12%) after an overnight fast on a 20 km cycling time trial performance. Nine recreationally active, healthy males (age: 24 ± 2 years; V˙O2max: 47 ± 5 mL·kg−1·min−1) participated in this study. A double-blind, placebo-controlled randomized study was conducted. Participants mouth-rinsed every 2.5 km for 5 s. Maltodextrin mouth rinse with concentrations of 3%, 6% or 12% did not change time to complete the time trial and power output compared to placebo (p > 0.05). Time trial completion times were 40.2 ± 4.0, 40.1 ± 3.9, 40.1 ± 4.4, and 39.3 ± 4.2 min and power output 205 ± 22, 206 ± 25, 210 ± 24, and 205 ± 23 W for placebo, 3%, 6%, and 12% maltodextrin conditions, respectively. Heart rate, lactate, glucose, and rating of perceived exertion did not differ between trials (p > 0.05). In conclusion, mouth rinsing with different maltodextrin concentrations after an overnight fast did not affect the physiological responses and performance during a 20 km cycling time trial in recreationally active males.

Assessment of facial paralysis (FP) and quantitative grading of facial asymmetry are essential in order to quantify the extent of the condition as well as to follow its improvement or progression. As such, there is a need for an accurate quantitative grading system that is easy to use, inexpensive and has minimal inter-observer variability. A comprehensive automated system to quantify and grade FP is the main objective of this work. An initial prototype has been presented by the authors. The present research aims to enhance the accuracy and robustness of one of this system's modules: the resting symmetry module. This is achieved by including several modifications to the computation method of the symmetry index (SI) for the eyebrows, eyes and mouth. These modifications are the gamma correction technique, the area of the eyes, and the slope of the mouth. The system was tested on normal subjects and showed promising results. The mean SI of the eyebrows decreased slightly from 98.42% to 98.04% using the modified method while the mean SI for the eyes and mouth increased from 96.93% to 99.63% and from 95.6% to 98.11% respectively while using the modified method. The system is easy to use, inexpensive, automated and fast, has no inter-observer variability and is thus well suited for clinical use.

We establish the efficacy of 2% viscous lidocaine in increasing oral intake in children with painful infectious mouth conditions compared with placebo. This was a randomized placebo-controlled trial of viscous lidocaine versus placebo at a single pediatric emergency department. Study staff, clinicians, nurses, caregivers, and participants were blinded to the group assignment. Children with acute infectious ulcerative mouth conditions (gingivostomatitis, ulcerative pharyngitis, or hand, foot, and mouth disease) and poor oral fluid intake were randomized to receive 0.15 mL/kg of either 2% viscous lidocaine or placebo with identical appearance and flavor. The primary outcome was the amount of fluid ingested in the 60 minutes after administration of the intervention, with a difference in intake of 4 mL/kg considered clinically important. Secondary outcomes were specific milliliter per kilogram fluid targets and incidence of adverse events. One hundred participants were recruited (50 per treatment group), all of whom completed the 60-minute fluid trial period. Oral intake 1 hour after drug administration was similar in both groups: lidocaine median 8.49 mL/kg (interquartile range 4.07, 13.84 mL/kg) versus placebo 9.31 mL/kg (interquartile range 3.06, 15.18 mL/kg); difference in medians 0.82 mL/kg (95% confidence interval -2.52 to 3.26); Mann-Whitney P=.90. Likewise, short-term secondary outcomes were similar between the groups and there were no adverse events in either group. Viscous lidocaine is not superior to a flavored gel placebo in improving oral intake in children with painful infectious mouth ulcers. Copyright © 2013 American College of Emergency Physicians.

Sleep paralysis (SP) is a cardinal symptom of narcolepsy. However, little is available in the literature about isolated sleep paralysis. This report discusses the case of a patient with isolated sleep paralysis who progressed from mild to severe SP over 8 years. He also restarted drinking alcohol to be able to fall asleep and allay his anxiety symptoms. The patient was taught relaxation techniques and he showed complete remission of the symptoms of SP on follow up after 8 months.

Background. Systemic sclerosis (SSc) is a multisystem disease characterized by cutaneous and visceral fibrosis. Face and mouth changes include telangiectasia, sicca syndrome, and thinning and reduction of mouth width (microcheilia) and opening (microstomia). We applied autologous fat transplantation compared with autologous adipose-derived stromal cells (ADSCs) injection to evaluate the clinical improvement of mouth opening. Methods. From February to May 2013 ten consecutive SSc patients were enrolled from the outpatient clinic of Plastic Surgery Department of Sapienza University of Rome. Patients were divided into two groups as follows: 5 patients were treated with fat transplantation and 5 patients received infiltration of ADSCs produced by cell factory of our institution. To value mouth opening, we use the Italian version of Mouth Handicap in Systemic Sclerosis Scale (IvMHISS). Mouth opening was assessed in centimetres (Maximal Mouth Opening, MMO). In order to evaluate compliance and physician and patient satisfaction, we employed a Questionnaire of Satisfaction and the Visual Analogic Scale (VAS) performed before starting study and 1 year after the last treatment. Results and Conclusion. We noticed that both procedures obtained significant results but neither one emerged as a first-choice technique. The present clinical experimentation should be regarded as a starting point for further experimental research and clinical trials. PMID:26880939

Besides the hereditary hyperkalaemic paralysis, a secondary form exists which often mimicks Guillain-Barre syndrome. A 62year old patient is reported on who developed severe hyperkalaemic paralysis on the basis of mild renal failure and additive spironolactone intake. Neurophysiological examinations disclosed normal muscle fibre activity but delayed nerve conduction velocities indicating that the mechanism underlying secondary hyperkalaemic paralysis is different from channelopathies. Haemodialysis led to complete recovery. Review of the medical literature showed that spironolactone intake is the most common cause of secondary hyperkalaemic paralysis. Typical symptoms are flaccid tetraplegia sparing the cranial nerves with only mild or lacking sensory impairment. Symptoms promptly resolve after haemodialysis or after glucose and insulin infusion. Only three out of 18 patients reviewed died, because of cardiopulmonary complications. Thus the prognosis of secondary hyperkalaemic paralysis is good. PMID:9489541

Neuromuscular retraining is an effective method for rehabilitating facial musculature in patients with facial paralysis. This nonsurgical therapy has demonstrated improved functional outcomes and is an important adjunct to surgical treatment for restoring facial movement. Treatment begins with an intensive clinical evaluation and incorporates appropriate sensory feedback techniques into a patient-specific, comprehensive, home therapy program. This article discusses appropriate patients, timelines for referral, and basic treatment practices of facial neuromuscular retraining for restoring function and expression to the highest level possible.

The management of facial paralysis is one of the most complex areas of reconstructive surgery. Given the wide variety of functional and cosmetic deficits in the facial paralysis patient, the reconstructive surgeon requires a thorough understanding of the surgical techniques available to treat this condition. This review article will focus on surgical management of facial paralysis and the treatment options available for acute facial paralysis (<3 weeks duration), intermediate duration facial paralysis (3 weeks to 2 yr) and chronic facial paralysis (>2 yr). For acute facial paralysis, the main surgical therapies are facial nerve decompression and facial nerve repair. For facial paralysis of intermediate duration, nerve transfer procedures are appropriate. For chronic facial paralysis, treatment typically requires regional or free muscle transfer. Static techniques of facial reanimation can be used for acute, intermediate, or chronic facial paralysis as these techniques are often important adjuncts to the overall management strategy.

To investigate the neurologic and functional effect of intracordal hyaluronate injections in acute unilateral vocal fold paralysis (UVFP) in a randomized controlled trial. In this open-label, randomized controlled study, 29 patients with UVFP were recruited within 6 months of their first outpatient visit and were randomized to receive either single hyaluronate injection (HI group) or conservative management (CM group). Quantitative laryngeal electromyography, videolaryngostroboscopy, UVFP-related quality of life (Voice Outcomes Survey, VOS), laboratory voice analysis, and health-related quality of life (SF-36) were evaluated at baseline, and at 1, 3 and 6 months post-injection in the HI group, and at baseline and 6 months in the CM group. Improvements in most quality of life domains and other assessments were comparable between the HI and CM groups; however, the HI group had a greater improvement in the mental health domain of quality of life at the end of follow-up. Early hyaluronate injection cannot improve nerve regeneration but can result in long-lasting improvements in patients' psychosocial well-being, thus highlighting the importance of early intervention for patients with UVFP.

The purpose of this study was to compare the effects of a cooling strategy designed to predominately lower thermal state with a strategy designed to lower thermal sensation on endurance running performance and physiology in the heat. Eleven moderately trained male runners completed familiarization and three randomized, crossover 5-km running time trials on a non-motorized treadmill in hot conditions (33 °C). The trials included ice slurry ingestion before exercise (ICE), menthol mouth rinse during exercise (MEN), and no intervention (CON). Running performance was significantly improved with MEN (25.3 ± 3.5 min; P = 0.01), but not ICE (26.3 ± 3.2 min; P = 0.45) when compared with CON (26.0 ± 3.4 min). Rectal temperature was significantly decreased with ICE (by 0.3 ± 0.2 °C; P < 0.01), which persisted for 2 km of the run and MEN significantly decreased perceived thermal sensation (between 4 and 5 km) and ventilation (between 1 and 2 km) during the time trial. End-exercise blood prolactin concentration was elevated with MEN compared with CON (by 25.1 ± 24.4 ng/mL; P = 0.02). The data demonstrate that a change in the perception of thermal sensation during exercise from menthol mouth rinse was associated with improved endurance running performance in the heat. Ice slurry ingestion reduced core temperature but did not decrease thermal sensation during exercise or improve running performance.

Background No licensed vaccine is currently available against serotype A foot-and-mouth disease (FMD) in China, despite the isolation of A/WH/CHA/09 in 2009, partly because this strain does not replicate well in baby hamster kidney (BHK) cells. Methodology/Principal Findings A novel plasmid-based reverse genetics system was used to construct a chimeric strain by replacing the P1 gene in the vaccine strain O/CHA/99 with that from the epidemic stain A/WH/CHA/09. The chimeric virus displayed growth kinetics similar to those of O/CHA/99 and was selected for use as a candidate vaccine strain after 12 passages in BHK cells. Cattle were vaccinated with the inactivated vaccine and humoral immune responses were induced in most of the animals on day 7. A challenge infection with A/WH/CHA/09 on day 28 indicated that the group given a 4-µg dose was fully protected and neither developed viremia nor seroconverted to a 3ABC antigen. Conclusions/Significance Our data demonstrate that the chimeric virus not only propagates well in BHK cells and has excellent antigenic matching against serotype A FMD, but is also a potential marker vaccine to distinguish infection from vaccination. These results suggest that reverse genetics technology is a useful tool for engineering vaccines for the prevention and control of FMD. PMID:23372840

Foot-and-mouth disease virus (FMDV) causes vesicular disease of cloven-hoofed animals with severe agricultural and economic implications. One of the most highly infectious and contagious livestock pathogens known, the disease spreads rapidly in naïve populations making it critical to have rapidly acting vaccines. Needle inoculation of killed virus vaccine is an efficient method of swiftly vaccinating large numbers of animals, either in eradication efforts or in outbreak situations in disease free countries, although, to be efficient, this requires utilizing the same needle with multiple animals. Here we present studies using a needle free system for vaccination with killed virus vaccine, FMDV strain O1 Manisa, as a rapid and consistent delivery platform. Cattle were vaccinated using a commercially available vaccine formulation at the manufacturer's recommended dose as well as four and sixteen fold less antigen load per dose. Animals were challenged intradermalingually (IDL) with live, virulent virus, homologous strain O1 Manisa, at various times following vaccination. All non-vaccinated control cattle exhibited clinical disease, including fever, viremia and lesions, specifically vesicle formation. Cattle vaccinated with the 1/16× and 1/4× doses using the needle free device were protected when challenged at both 7 and 28 days after vaccination. These data suggest that effective protection against disease can be achieved with 1/16 of the recommended vaccine dose when delivered using the needle free, intradermal delivery system, indicating the current vaccine stockpile that can be extended by many fold using this system.

Thirty patients with a wide range of sore mouth that led to the diagnosis of iron deficiency in 12 patients, pernicious anemia in 8 patients, combined deficiency of iron and vitamin B12 in 2 patients, and anemia of chronic disease in 8 patients were investigated. The oral signs and symptoms included glossitis, glossodynia, angular cheilitis, recurrent oral ulcer, oral candidosis, diffuse erythematous mucositis, and pale oral mucosa. The values of hemoglobin in 30 patients varied from normal to severe life-threatening levels, but none had developed generalized symptoms sufficiently advanced to arouse suspicions of anemia before they visited the Oral Medicine Clinic. The aim of this paper is to describe a retrospective study of 30 patients with oral changes as the initial manifestation of nutritional deficiency or anemia of chronic diseases. Improved diagnosis and classification of anemia based on the mean and heterogeneity of red cell size will be discussed.

Oral cancer is a potentially preventable disease due to its association with well-known risk factors and easy detectability. There is a significant deficiency in the awareness of oral cancer and its risk factors among the public. Raising public awareness could effectively contribute to achieving a significant reduction in the incidence of oral cancer. The objective of this study was to evaluate the effectiveness of mouth self-examination (MSE) in improving the awareness of oral cancer and its risk factors as well as test its feasibility as an oral cancer-screening tool. The study was carried out in a high-risk population of 57,704 from India, of which, 34,766 individuals who have met the eligibility criteria formed the study population. MSE brochures and trained health workers were employed for the purpose of health education and cancer screening. The present study compared their efficacy to detect oral lesions. Subjects with suspicious lesions were referred to the trained oral cancer specialist for confirmation. A questionnaire to assess the awareness of oral cancer and its risk factors was developed and validated. SPSS (v.11.0) was used for data analysis. The program identified 216 cases of potentially malignant lesions as well as three cases of oral cancer. The findings of MSE and health workers showed 72% concordance, while that of health workers and oral cancer specialist showed 100% concordance. MSE had a low sensitivity of 18%, while the specificity was 99.9%. Though the technique identified high-risk lesions such as red patches (66.7%) and non-healing ulcers (42.9%), the detection rate of white patches was low (12.7%). Overall awareness of oral cancer and its risk factors after introduction of MSE program was over 80%; but the compliance to seek treatment was poor (32%). Mouth self-examination may be used as an effective tool to improve the awareness of oral cancer and for the early detection of lesions.

Limb paralysis can develop for various reasons. We found a 13-year-old patient who became paralyzed in her lower extremities after laparoscopic appendectomy. Some tests, including electrodiagnostic studies and magnetic resonance imaging, were performed to evaluate the cause of lower limb paralysis. None of the tests yielded definite abnormal findings. We subsequently decided to explore the possibility of psychological problems. The patient was treated with simultaneous rehabilitation and psychological counseling. Paralysis of the patient's lower extremity improved gradually and the patient returned to normal life. Our findings indicate that psychological problems can be related to limb paralysis without organ damage in patients who have undergone laparoscopic surgical procedures. PMID:25426280

Periodic paralyses are neuromuscular disorders characterized by attacks of muscle weakness coinciding with changes in blood potassium levels. They are thus classified as hypokalaemic, normokalaemic or hyperkalaemic. Most forms are genetic, with autosomal dominant inheritance. These diseases are channelopathies, i.e. caused by mutations in ion channel genes. The culprit genes encode muscle sodium, calcium and potassium channels. Mutations in calcium or potassium channels cause periodic paralyses of the same type (hypokalaemic periodic paralysis or Andersen-Tawil Syndrome). In contrast, distinct mutations in the gene encoding the sodium channel can cause the entire range of periodic paralysis (hypokalaemic, normokalaemic or hyperkalaemic). The physiological consequences of mutations have been studied with patch-clamp techniques and electromyography. Generally speaking, mutations alter the excitability cycle of the muscle membrane, resulting in a loss of function (paralysis). Electromyographic studies have demonstrated a good correlation between symptoms and physiological parameters, giving rise to a classification that can help orient the molecular diagnosis. Work on the genetics and pathophysiology of periodic paralyses has helped to improve the diagnosis and management of these syndromes.

A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself.

Hypokalemic periodic paralysis is a rare genetic disorder characterized by recurrent attacks of skeletal muscle weakness with associated hypokalemia which is precipitated by stress, cold, carbohydrate load, infection, glucose infusion, hypothermia, metabolic alkalosis, anesthesia, and steroids. We encountered one such incidence of prolonged recovery after general anesthesia, which on further evaluation revealed a case of hypokalemic paralysis. The key to successful management of such a patient was vigilant pre-operative evaluation, perioperative monitoring, and aggressive treatment of hypokalemia when it occurs. PMID:23833504
Hyperthyroid periodic paralysis (HPP) is a rare life threatening complication of hyperthyroidism commonly occurring in young Asian males but sporadically found in other races. It is characterised by hypokalemia and acute onset paraparesis with prevalence of one in one hundred thousand (1 in 100000). The symptoms resolve promptly with potassium supplementation. Nonselective beta blockers like propranol can also be used to ameliorate and prevent subsequent paralytic attack. We report a case of 22 year old male presenting with hyperthyroid periodic paralysis (HPP) having very low serum potassium level. PMID:27648066

Sepsis develops when the initial host response is unable to contain the primary infection, resulting in widespread inflammation and multiple organ dysfunction. The impairment of neutrophil migration into the infection site, also termed neutrophil paralysis, is a critical hallmark of sepsis, which is directly related to the severity of the disease. Although the precise mechanism of this phenomenon is not fully understood, there has been much advancement in the understanding of this field. In this review, we highlight the recent insights into the molecular mechanisms of neutrophil paralysis during sepsis.

Vocal fold paralysis (VFP) is a relatively common cause of stridor and dysphonia in the paediatric population. This report summarises our experience with VFP in the paediatric age group. All patients presenting with vocal fold paralysis over a 12-month period were included. Medical charts were revised retrospectively. The diagnosis was performed by flexible endoscopic examination. The cases were evaluated with respect to aetiology of the paralysis, presenting symptoms, delay in diagnosis, affected side, vocal fold position, need for surgical treatment and outcome. The presenting symptoms were stridor and dysphonia. Iatrogenic causes formed the largest group, followed by idiopathic, neurological and obstetric VFP. Unilateral paralysis was found in most cases. The median value for delay in diagnosis was 1 month and it was significantly higher in the iatrogenic group. Surgical treatment was not necessary in most part of cases. The diagnosis of VFP may be suspected based on the patient's symptoms and confirmed by flexible endoscopy. Infants who develop stridor or dysphonia following a surgical procedure have to be examined without delay. The surgeon has to keep in mind that there is a possibility of late spontaneous recovery or compensation. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Oral mucositis (OM) is a frequently encountered problem as a complication of cancer treatment. We investigated whether daily washings with colchicine solution improved mucositis in patients with hematological malignancies undergoing chemotherapy. This study was a one-arm, nonrandomized clinical trial that used a historical control group. Patients were included in the study from the first day of mucositis and followed up until discharge. Patients received 2 mg colchicine mouthwashes daily for 5 days or saline solution. OM was assessed once daily until symptom resolution, using the WHO grading scale of 0-4 and a visual analogue scale. We determined that at least 40 patients in the colchicine group would be needed to detect a 20% difference in the duration of OM between Groups A and B, with a 95% confidence level and a power of 80%. 82 patients were included in the final analysis, 40 in the colchicine group and 42 in the control group. Median duration of OM was significantly different among groups; 9 days (range 1-17 days) for the control group versus 6 days (range 3-13 days) for those exposed to colchicine mouthwash (p = .028). The median days of regression of mucosal lesions were significantly different (p = .047) among the control group (7 days [range 3-20]) compared to the colchicine group (4 days [range 2-14]). Although our findings suggest that colchicine mouthwash is helpful in reducing the severity and duration of chemotherapy-induced OM, randomized trials are needed to confirm these results.

Sleep paralysis is a sensation of an inability to speak or move other muscles when falling asleep or awakening. Sleep paralysis by itself has been reported as occurring infrequently and many clinicians are uncertain of its significance. In contrast, sleep paralysis in conjunction with sleep attacks has been reported as a concomitant of narcolepsy. To further examine the incidence of sleep paralysis, the responses of 80 first-year medical students, 16.25% had experienced predormital, postdormital, or both types of sleep paralysis. These episodes occurred infrequently--only once or twice for most of these students. Reports of sleep paralysis were not associated with sleep attacks or cataplexy. These results support two previous studies which found that sleep paralysis alone occurs frequently among normals.
Thyrotoxic hypokalemic periodic paralysis (TPP) is a condition characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. We describe two cases of thyrotoxic periodic paralysis who presented to our hospital with potassium values of 1.3 MeQ/l and 1.2 MeQ/l, respectively. Surprisingly, the two patients had no documented past medical history. Based on the clinical features of high heart rate, palpitations (seen in both the patients), and exophthalmos (seen in one patient), thyrotoxic periodic paralysis was suspected. A thorough laboratory workup confirmed the diagnosis of thyrotoxicosis. Beta blockers were initiated promptly, along with intravenous potassium chloride, and the patients eventually improved symptomatically. These patients were eventually diagnosed with Graves’ disease and were placed on methimazole, which prevented further attacks. Thyroid periodic paralysis (TPP) is a rare clinical manifestation of hyperthyroidism. Patients present with sudden onset paralysis associated with severe hypokalemia. The presence of paralysis and hypokalemia in a patient who has a history of hyperthyroidism should prompt the physician about thyrotoxic periodic paralysis. A high index of suspicion, prompt diagnosis, and management of the condition can prevent severe complications, such as cardiac arrhythmias. PMID:26623197

Muscle tendon unit (MTU) transfer is a common procedure performed to restore hand function after peripheral nerve or spinal cord injury. The principles of MTU transfer established for hand surgery can be adopted to optimize the dynamic excursion of the temporalis tendon transfer procedure for facial reanimation. Additionally, the force generating ability of a transferred MTU depends on the ideal length-tension relationship of the donor muscle. There are unclear guideline for selecting the ideal tension at which a transferred MTU will generate maximum force and excursion and current practice often leads to overstretch and suboptimal actin myosin interaction. The use of intraoperative electrical stimulation is an option for determining the ideal tension to optimize excursion of transferred temporalis tendon units in simile restoration. Understanding the biomechanics and principles of MTU and applying it to the temporalis tendon transfer procedure is necessary to improve its use in facial reanimation.

Sleep paralysis is a relatively new term to describe what for hundreds of years many believed to be a visitation by a malevolent creature which attacked its victims as they slept. The first clinical description of sleep paralysis was published in 1664 in a Dutch physician's case histories, where it was referred to as, 'Incubus or the Night-Mare [sic]'. In 1977, it was discovered more than 100 previously healthy people from various South East Asian communities had died mysteriously in their sleep. The individuals affected were dying at a rate of 92/100,000 from Sudden Unexplained Nocturnal Death Syndrome. No underlying cause was ever found, only that subsequent studies revealed a high rate of sleep paralysis and belief in the dab tsog (nightmare spirit) amongst members of the community. The nightmare/succubus is descended from Lilith. The earliest reference to Lilith is found in the Sumerian King list of 2400 BC known as Lilitu or she-demon, she bore children from her nocturnal unions with men. In other derivations, she was Adam's first wife who rather than 'obey' became a demon that preyed on women during childbirth. In modern Middle Eastern maternity wards, some women still wear amulets for protection. Today, clinical cause of these disturbances is sleep paralysis due to the unsuitable timing of REM sleep. During the 'Nightmare' episode, the sleeper becomes partially conscious during REM cycle, leaving the individual in a state between dream and wakefulness. For some, culture and the tradition of the nightmare is explanation enough.

Complete flaccid facial paralysis, as well as the synkinetic and hyperkinetic sequelae of partial recovery, has significant impact on quality of life. Patients suffer from functional deficiencies, cosmetic deformity, discomfort and social consequences leading to emotional distress. Despite an extensive and sophisticated array of available interventions for facial reanimation, most patients have persistent issues that require consistent follow-up. In long-term management, botulinum toxin (BT) injection remains a critical tool in the treatment of the facial paralysis patient, particularly in the case of synkinesis, hyperkinesis and imbalance. We review the recent scientific literature and highlight key principles and developments in the use of BT in the management of facial paralysis, including less common applications for acute facial paralysis, hyperlacrimation and pseudoptosis. We reviewed the literature for the latest advances in the use of BT in facial paralysis, including applications and technique, as well as measurement tools and adjunct exercises. We also share our experience in treating our own patient population. BT continues to be a well tolerated and effective tool in the long-term management of facial paralysis, specifically in treating synkinesis, imbalance and hyperkinesis, as well as hyperlacrimation and pseudoptosis. Consistent measurement tools and adjunct neuromuscular retraining are crucial in the successful deployment of BT. Controversy exists as to whether BT should be used to manage facial paralysis during the acute phase, and whether BT application to the nonparalyzed face can improve long-term recovery in the paralyzed side.

We have rationally engineered foot-and-mouth disease virus to increase its stability against thermal dissociation into subunits without disrupting the many biological functions needed for its infectivity. Amino acid side chains located near the capsid intersubunit interfaces and either predicted or found to be dispensable for infectivity were replaced by others that could establish new disulfide bonds or electrostatic interactions between subunits. Two engineered viruses were normally infectious, genetically stable, and antigenically indistinguishable from the natural virus but showed substantially increased stability against irreversible dissociation. Electrostatic interactions mediated this stabilizing effect. For foot-and-mouth disease virus and other viruses, some evidence had suggested that an increase in virion stability could be linked to an impairment of infectivity. The results of the present study show, in fact, that virion thermostability against dissociation into subunits may not be selectively constrained by functional requirements for infectivity. The thermostable viruses obtained, and others similarly engineered, could be used for the production, using current procedures, of foot-and-mouth disease vaccines that are less dependent on a faultless cold chain. In addition, introduction of those stabilizing mutations in empty (nucleic acid-free) capsids could facilitate the production of infection-risk-free vaccines against the disease, one of the economically most important animal diseases worldwide.
Rehabilitation takes an important part in the treatment of facial paralysis, especially when these are severe. It aims to lead the recovery of motor activity and prevent or reduce sequelae like synkinesis or spasms. It is preferable that it be proposed early in order to set up a treatment plan based on the results of the assessment, sometimes coupled with an electromyography. In case of surgery, preoperative work is recommended, especially in case of hypoglossofacial anastomosis or lengthening temporalis myoplasty (LTM). Our proposal is to present an original technique to enhance the sensorimotor loop and the cortical control of movement, especially when using botulinum toxin and after surgery.

Mouth rinsing with carbohydrate (CHO) solutions during cycling time trials results in performance enhancements; however, most studies have used approximately 6% CHO solutions. Therefore, the purpose of this study was to compare the effectiveness of mouth rinsing with 4, 6, and 8% CHO solutions on 1-hour simulated cycling time trial performance. On 4 occasions, 7 trained male cyclists completed at the postprandial period, a set amount of work as fast as possible in a randomized counterbalanced order. The subjects rinsed their mouth for 5 seconds, on completion of each 12.5% of the trial, with 25 ml of a non-CHO placebo and 4, 6, and 8% CHO solutions. No additional fluids were consumed during the time trial. Heart rate (HR), ratings of perceived exertion (RPE), thirst (TH), and subjective feelings (SF) were recorded after each rinse. Furthermore, blood samples were drawn every 25% of the trial to measure blood glucose and blood lactate concentrations, whereas whole-body CHO oxidation was monitored continuously. Time to completion was not significant between conditions with the placebo, 4, 6, and 8% conditions completing the trials in 62.0 ± 3.0, 62.8 ± 4.0, 63.4 ± 3.4, and 63 ± 4.0 minutes, respectively. There were no significant differences between conditions in any of the variables mentioned above; however, significant time effects were observed for HR, RPE, TH, and SF. Post hoc analysis showed that TH and SF of subjects in the CHO conditions but not in the placebo were significantly increased by completion of the time trial. In conclusion, mouth rinsing with CHO solutions did not impact 1-hour cycling performance in the postprandial period and in the absence of fluid intake. Our findings suggest that there is scope for further research to explore the activation regions of the brain and whether they are receptive to CHO dose, before specific recommendations for athletic populations are established. Consequently, mouth rinsing as a practical strategy for coaches

Burning mouth syndrome is distressing to both the patient and practitioner unable to determine the cause of the patient's symptoms. Burning mouth syndrome is a diagnosis of exclusion, which is used only after nutritional deficiencies, mucosal disease, fungal infections, hormonal disturbances and contact stomatitis have been ruled out. This article will explore the many causes and treatment of patients who present with a chief complaint of "my mouth burns," including symptomatic treatment for those with burning mouth syndrome.

Idiopathic facial palsy is the most common cause of facial nerve palsy in children. Controversy exists regarding treatment options. The objectives of this study were to review the epidemiological and clinical characteristics as well as the outcome of idiopathic facial palsy in children to suggest appropriate treatment. A retrospective study was conducted on children with a diagnosis of idiopathic facial palsy from 2007 to 2012. A total of 37 cases (13 males, 24 females) with a mean age of 13.9 years were included in this analysis. The mean duration between onset of Bell's palsy and consultation was 3 days. Of these patients, 78.3% had moderately severe (grade IV) or severe paralysis (grade V on the House and Brackmann grading). Twenty-seven patients were treated in an outpatient context, three patients were hospitalized, and seven patients were treated as outpatients and subsequently hospitalized. All patients received corticosteroids. Eight of them also received antiviral treatment. The complete recovery rate was 94.6% (35/37). The duration of complete recovery was 7.4 weeks. Children with idiopathic facial palsy have a very good prognosis. The complete recovery rate exceeds 90%. However, controversy exists regarding treatment options. High-quality studies have been conducted on adult populations. Medical treatment based on corticosteroids alone or combined with antiviral treatment is certainly effective in improving facial function outcomes in adults. In children, the recommendation for prescription of steroids and antiviral drugs based on adult treatment appears to be justified. Randomized controlled trials in the pediatric population are recommended to define a strategy for management of idiopathic facial paralysis. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

This study examined ratings of two subjective aspects (moisturization and dry mouth relief) that may be changed following the use of dry mouth relief products (an oral gel, an oral rinse, or a mouth spray), in comparison to water over a period of four hours following a single supervised use on two separate occasions. This was a single-center, two site, randomized, examiner blind, four treatment arm, stratified (by dry mouth screening score at baseline), parallel group study in healthy subjects with a self-reported feeling of dry mouth. Prior to product use, subjects rated their current subjective perception of moisturization and dry mouth on an 11-point scale. Subjects then rated the two questions immediately after product use and 30, 60, 90, 120, and 240 minutes later. At the 240-minute time point, subjects also rated global efficacy questions regarding "overall" and "long-lasting" moisturization and dry mouth relief, and overall product opinion. Subjects then used their assigned products at home for three days and the procedures were repeated on Day 4. In total, 300 subjects were randomized to treatment. Compared with water, all test products showed statistically significantly greater improvements over baseline on both Day 1 and Day 4 at most time points, on the area under the curve from baseline for the moisturization and dryness questions, and after 240 minutes for the global efficacy and overall opinion assessments (all p < 0.05). There was a statistically significant difference between the pre-dosing assessments on Day 1 versus Day 4 (p < 0.001) for both efficacy questions. Products were generally well-tolerated. Three different types of dry mouth relief products were shown to provide significant relief of dry mouth and increased feelings of moisturization compared to water using subjective questionnaires.

This article presents an overview of the sleep paralysis experience from both a cultural and a historical perspective. The robust, complex phenomenological pattern that represents the subjective experience of sleep paralysis is documented and illustrated. Examples are given showing that, for a majority of subjects, sleep paralysis is taken to be a kind of spiritual experience. This is, in part, because of the very common perception of a non-physical 'threatening presence' that is part of the event. Examples from various cultures, including mainstream contemporary America which has no widely known tradition about sleep paralysis, are used to show that the complex pattern and spiritual interpretation are not dependent on cultural models or prior learning. This is dramatically contrary to conventional explanations of apparently 'direct' spiritual experiences, explanations that are summed up as the 'Cultural Source Hypothesis.' This aspect of sleep paralysis was not recognized through most of the twentieth century. The article examines the way that conventional modern views of spiritual experience, combined with medical ideas that labeled 'direct' spiritual experiences as psychopathological, and mainstream religious views of such experiences as heretical if not pathological, suppressed the report and discussion of these experiences in modern society. These views have resulted in confusion in the scientific literature on sleep paralysis with regard to its prevalence and core features. The article also places sleep paralysis in the context of other 'direct' spiritual experiences and offers an 'Experiential Theory' of cross-culturally distributed spiritual experiences.

A new self-microemulsifying mouth dissolving film (SMMDF) for poorly water-soluble drugs such as indomethacin was developed by incorporating self-microemulsifying components with solid carriers mainly containing microcrystalline cellulose, low-substituted hydroxypropyl cellulose and hypromellose. The uniformity of dosage units of the preparation was acceptable according to the criteria of Chinese Pharmacopoeia 2010. The SMMDF was disintegrated within 20 s after immersion into water, released completely at 5 min in the dissolution medium and achieved microemulsion particle size of 28.81 ± 3.26 nm, which was similar to that of liquid self- microemulsifying drug delivery system (SMEDDS). Solid state characterization of the SMMDF was performed by SEM, DSC and X-ray powder diffraction. Results demonstrated that indomethacin in the SMMDF was in the amorphous state, which might be due to self-microemulsifying ingredients. Pharmacokinetic parameters in rats including T(max), C(max), AUC were similar between the SMMDF and liquid SMEDDS. AUC and C(max) from the SMMDF were significantly higher than those from the common mouth dissolving film or the conventional tablet, and Tmax from SMMDF group was also significantly decreased. These findings suggest that the SMMDF is a new promising dosage form, showing notable characteristics of convenience, quick onset of action and enhanced oral bioavailability of poorly water-soluble drugs.

Seventeen cases of late ulnar paralysis treated by neurolysis-transposition are reported. The clinical characteristics of these paralysis are emphasized. A very prolonged symptom free interval, a rapid onset and a severe involvement. The ulnar transposition was most often done subcutaneously. Cubitus valgus and definite nerve compression proximal to the arcade of the flexor carpi ulnaris muscle are almost always present. The results as regards the neuropathy are notable: no patient is completely cured and only half are improved. An anatomical study of the nerve path shows the essential role, in the compression of the nerve, of the muscular arcade of the flexor carpi ulnaris muscle which acts in a way similar to the bridge of a violin. Hence, opening it longitudinally is the principal procedure of the neurolysis. This should be routine before the first signs of neuropathy occur in an elbow whose axis is out of alignment as a sequela of a childhood injury.

Traditional and contemporary Inuit concepts of sleep paralysis were investigated through interviews with elders and young people in Iqaluit, Baffin Island. Sleep paralysis was readily recognized by most respondents and termed uqumangirniq (in the Baffin region) or aqtuqsinniq (Kivalliq region). Traditional interpretations of uqumangirniq referred to a shamanistic cosmology in which the individual's soul was vulnerable during sleep and dreaming. Sleep paralysis could result from attack by shamans or malevolent spirits. Understanding the experience as a manifestation of supernatural power, beyond one's control, served to reinforce the experiential reality and presence of the spirit world. For contemporary youth, sleep paralysis was interpreted in terms of multiple frameworks that incorporated personal, medical, mystical, traditional/shamanistic, and Christian views, reflecting the dynamic social changes taking place in this region.

Kawasaki disease (KD) is a multisystem disorder with varying clinical expression. We describe an instance of facial nerve paralysis in a patient with KD. A 5-month-old boy developed fever, irritability, and diarrhea, treated 8 days later with cefaclor and ibuprofen. Three days later a confluent, erythematous and papular rash appeared, his lips were reddened and swollen, and his white blood count and platelet count were 20,900/mm(3) and 558,000/mm(3), respectively. He was admitted to the hospital with a diagnosis of KD, and an echocardiogram showed a right coronary aneurysm. The patient then developed an acute, right-sided, facial nerve peripheral paralysis that resolved over the next 6 weeks. He was treated with intravenous immune globulin (IVIG) 2 g/kg and aspirin 100 mg/kg/day with improvement of signs and symptoms. This report documents facial nerve paralysis as an uncommon complication of KD and points out that it may be a marker of increased risk of cardiovascular disease in this disorder.

Pain in the tongue or oral tissues described as "burning" has been referred to by many terms including burning mouth syndrome. When a burning sensation in the mouth is caused by local or systemic factors, it is called secondary burning mouth syndrome and when these factors are treated the pain will resolve. When burning mouth syndrome occurs in the absence of identified risk indicators, the term primary burning mouth syndrome is utilized. This article focuses on descriptions, etiologic theories, and management of primary burning mouth syndrome, a condition for which underlying causative agents have been ruled out.

Burning mouth syndrome (BMS) is a chronic condition characterized by burning of the oral mucosa, with or without dysgeusia and xerostomia, in the setting of no underlying systemic disease or identifiable abnormalities on physical examination or laboratory testing. BMS disproportionately affects postmenopausal women. The pathophysiology of the disease is unknown; no single treatment has proven universally successful. In light of these shortcomings, having a practical approach to the evaluation and management of patients with BMS can improve both patient quality of life and physician satisfaction.

In this retrospective study we used a modified surgical technique for midface reanimation in patients with facial nerve paralysis. Facial atonicity can cause functional impairment regarding speech articulation, oral competence, breathing, and eyelid closure. Furthermore, esthetic and psychological aspects play an important role in patients' emotional interaction and social integration. The chosen rehabilitative technique should offer support against prolapse of facial structures and remedy of functional disabilities and, thereby, prevention of social stigmatization due to disease-related changes in appearance. Between 2005 and 2013, fascia lata grafts were used as static support in 15 cases of unilateral facial paralysis. Two fascia lata grafts were subcutaneously inserted in the upper and lower lips crossing the midline and sutured at 4 points, including the unaffected part of the orbicularis oris muscle and modiolus. The slings were suspended against the zygomatic arch with an osteosynthesis plate. The patients perceived surgery results as considerably improving their appearance, speech, and alimentation. In 93.3% of cases, no postoperative complications occurred. The follow-up results (8 months to 8 years) remained stable. This retrospective study showed the advantages of static facial reanimation in appropriate cases. The bony fixated support of the fascial slings allows an immediate improvement of facial symmetry. Additional attachment points including the unaffected part of the orbicularis oris muscle and the use of 2 independent fascia lata slings allow a more accurate adjustment of suspension forces and an incomplete dynamic reanimation of the mouth corner. With respect to its simplicity and minimal invasiveness, this surgical procedure is associated with low morbidity and rapid improvement of the patient's esthetic appearance.

Thyrotoxic periodic paralysis is a potentially life-threatening condition associated with recurrent episodes of muscle weakness and hypokalaemia due to hyperthyroidism. Diagnosis is often delayed or misdiagnosed due to its rarity in the western world and subtle features of hyperthyroidism on initial presentation. Here we present the case of a 25-year-old man who presented to the emergency department (ED) with sudden onset weakness of bilateral upper and lower extremities. His labs revealed hypokalaemia with elevated T4 and suppressed thyroid-stimulating hormone and he was diagnosed with thyrotoxic periodic paralysis. He was treated with potassium repletion, atenolol and methimazole with complete reversal of his paralysis within the next day. Unfortunately, he failed to keep the follow-up appointment after discharge, ran out of his methimazole and landed up in the ED again. 2017 BMJ Publishing Group Ltd.

Foot-and-mouth disease (FMD) has a major economic impact throughout the world and is a considerable threat to food security. Current FMD virus (FMDV) vaccines are made from chemically inactivated virus and need to contain intact viral capsids to maximize efficacy. FMDV exists as seven serotypes, each made up by a number of constantly evolving subtypes. A lack of immunological cross-reactivity between serotypes and between some strains within a serotype greatly complicates efforts to control FMD by vaccination. Thus, vaccines for one serotype do not afford protection against the others, and multiple-serotype-specific vaccines are required for effective control. The FMDV serotypes exhibit variation in their thermostability, and the capsids of inactivated preparations of the O, C and SAT serotypes are particularly susceptible to dissociation at elevated temperature. Methods to quantify capsid stability are currently limited, lack sensitivity and cannot accurately reflect differences in thermostability. Thus, new, more sensitive approaches to quantify capsid stability would be of great value for the production of more stable vaccines and to assess the effect of production conditions on vaccine preparations. Here we have investigated the application of a novel methodology (termed PaSTRy) that utilizes an RNA-binding fluorescent dye and a quantitative (q)PCR machine to monitor viral genome release and hence dissociation of the FMDV capsid during a slow incremental increase in temperature. PaSTRy was used to characterize capsid stability of all FMDV serotypes. Furthermore, we have used this approach to identify stabilizing factors for the most labile FMDV serotypes.

The pathogenesis of thyrotoxic periodic paralysis has long been thought related to increased Na(+)-K(+) ATPase activity stimulated by thyroid hormone and/or hyperadrenergic activity and hyperinsulinemia. This mechanism alone, however, cannot adequately explain how hypokalemia occurs during acute attacks or the associated paradoxical depolarization of the resting membrane potential. Recent findings that loss of function mutations of the skeletal muscle-specific inward rectifying K(+) (Kir) channel, Kir2.6, associate with thyrotoxic periodic paralysis provide new insights into how reduced outward K(+) efflux in skeletal muscle, from either channel mutations or inhibition by hormones (adrenalin or insulin), can lead to a vicious cycle of hypokalemia and paradoxical depolarization, which in turn, inactivates Na(+) channels and causes muscle unexcitability and paralysis.

Facial paralysis can result in serious ocular consequences. All patients with orbicularis oculi weakness in the setting of facial nerve injury should undergo a thorough ophthalmologic evaluation. The main goal of management in these patients is to protect the ocular surface and preserve visual function. Patients with expected recovery of facial nerve function may only require temporary and conservative measures to protect the ocular surface. Patients with prolonged or unlikely recovery of facial nerve function benefit from surgical rehabilitation of the periorbital complex. Current reconstructive procedures are most commonly intended to improve coverage of the eye but cannot restore blink.

Secondary hyperkalaemic paralysis is a rare condition often mimicking the Guillain-Barré syndrome. There have been a few case reports of hyperkalaemia caused by renal failure, trauma, and drugs where the presentation has been with muscle weakness. A case of hyperkalaemic paralysis caused by an angiotensin converting enzyme inhibitor is reported. Keywords: hyperkalaemia; paralysis; ACE inhibitors PMID:11161080

Laparoscopic radical prostatectomy (LARP) has been accepted as first line therapy for clinically localized prostate cancer. Complications have been low and outcomes are comparable to that of open surgery with potential benefits including shorter hospital stay, less pain and quicker return to normal activity. Unexplained paralysis following LARP is a rare entity with no reported cases in the current literature. We report a case of complete motor paralysis following LARP. An extensive multidisciplinary evaluation did not definitively establish a diagnosis. Aggressive multimodality treatment led to a complete recovery. Our understanding of this phenomena with the possible etiology and treatment is discussed.

Herpes zoster may, in some instances, cause motor paralysis as well as the usual sensory and cutaneous manifestations. It is suggested that the presence of electromyographic denervation potentials be used as the criterion of muscle paresis in order to avoid mistaking atrophy of disuse for true lower motor neuron disease. Use of the proper physical therapy procedures hastens the recovery of function and may serve to retard denervation atrophy and fibrosis in patients with muscle paralysis.

Idiopathic diaphragm paralysis is probably more common and responsible for more morbidity than generally appreciated. Bell's palsy, or idiopathic paralysis of the seventh cranial nerve, may be seen as an analogous condition. The roles of zoster sine herpete and herpes simplex have increasingly been recognized in Bell's palsy, and there are some data to suggest that antiviral therapy is a useful adjunct to steroid therapy. Thus, we postulated that antiviral therapy might have a positive impact on the course of acute idiopathic diaphragm paralysis which is likely related to viral infection. Three consecutive patients with subacute onset of symptomatic idiopathic hemidiaphragm paralysis were empirically treated with valacyclovir, 1,000 mg twice daily for 1 week. Prior to therapy, diaphragmatic function was assessed via pulmonary function testing and two-dimensional B-mode ultrasound, with testing repeated 1 month later. Diaphragmatic function pre- and post-treatment was compared to that of a historical control group of 16 untreated patients. All three subjects demonstrated ultrasound recovery of diaphragm function 4-6 weeks following treatment with valacyclovir. This recovery was accompanied by improvements in maximum inspiratory pressure (PI(max)) and vital capacity (VC). In contrast, in the untreated cohort, diaphragm recovery occurred in only 11 subjects, taking an average of 14.9 +/- 6.1 months (mean +/- SD). The results of this small, preliminary study suggest that antiviral therapy with valacyclovir may be helpful in the treatment of idiopathic diaphragm paralysis induced by a viral infection.

Summary: Facial nerve paralysis because of penetrating trauma through the external auditory canal is extremely rare, with a paucity of published literature. The objective of this study is to review the literature on transtympanic facial nerve paralysis and increase physician awareness of this uncommon injury through discussion of its clinical presentation, management and prognosis. We also aim to improve patient outcomes in those that have sustained this type of injury by suggesting an optimal management plan. In this case report, we present the case of a 46-year-old white woman who sustained a unilateral facial nerve paresis because of a garfish penetrating her tympanic membrane and causing direct damage to the tympanic portion of her facial nerve. On follow-up after 12 months, her facial nerve function has largely returned to normal. Transtympanic facial nerve paralysis is a rare injury but can have a favorable prognosis if managed effectively. PMID:26090278

Periodic paralysis is a rare disorder that causes episodes of severe muscle weakness that can be confused with other diseases, including epilepsy or myasthenia gravis. Hyperkalemic and hypokalemic paralysis are included within these diseases, the latter being divided into periodic paralysis (familial, thyrotoxic or sporadic) and non-periodic paralysis. In this regard, we present a case of familial hypokalemic periodic paralysis in an eighteen year-old female who was diagnosed with epilepsy in childhood, as well as a subclinical hypothyroidism (for which she received replacement therapy) months ago. The diagnosis was made by the anamnesis and the confirmation of hypokalemia.

Parotid lymphangioma is a relatively rare disease that is usually detected in infancy or early childhood, and which has typical features. Clinical reports of facial nerve paralysis caused by lymphangioma, however, are very rare. Usually, facial nerve paralysis in a child suggests malignancy. Here we report a very rare case of parotid lymphangioma associated with facial nerve paralysis. A 7-year-old boy was admitted to hospital with a rapidly enlarging mass in the left parotid region. Left peripheral-type facial nerve paralysis was also noted. Computed tomography and magnetic resonance imaging also revealed multiple cystic lesions. Open biopsy was undertaken in order to investigate the cause of the facial nerve paralysis. The histopathological findings of the excised tumor were consistent with lymphangioma. Prednisone (40 mg/day) was given in a tapering dose schedule. Facial nerve paralysis was completely cured 1 month after treatment. There has been no recurrent facial nerve paralysis for eight years.

Facial paralysis is a frequently-occurring disease, which causes the loss of the voluntary muscles on one side of the face due to the damages the facial nerve and results in an inability to close the eye and leads to dropping of the angle of the mouth. There have been few objective methods to quantitatively diagnose it and assess this disease for clinically treating the patients so far. The skin temperature distribution of a healthy human body exhibits a contralateral symmetry. Facial paralysis usually causes an alteration of the temperature distribution of body with the disease. This paper presents the use of the histogram distance of bilateral local binary pattern (LBP) in the facial infrared thermography to measure the asymmetry degree of facial temperature distribution for objective assessing the severity of facial paralysis. Using this new method, we performed a controlled trial to assess the facial nerve function of the healthy subjects and the patients with Bell's palsy respectively. The results showed that the mean sensitivity and specificity of this method are 0.86 and 0.89 respectively. The correlation coefficient between the asymmetry degree of facial temperature distribution and the severity of facial paralysis is an average of 0.657. Therefore, the histogram distance of local binary pattern in the facial infrared thermography is an efficient clinical indicator with respect to the diagnosis and assessment of facial paralysis.
To describe a patient who presented with psychopathology in the wake of sleep paralysis and hypnopompic hallucinations, and to discuss the importance of these phenomena to psychiatric diagnoses. Case report. A 25-year-old black South African woman developed paranoid beliefs and a sad and anxious mood in the wake of her first experience of sleep paralysis and hypnic hallucinations. She had no history of other sleep-related events. Reassurance, explanation of the physiological basis of her experience, and a short course of low-dose diazepam were provided. Her mood and sleep improved promptly and she no longer held paranoid beliefs. She did not experience further episodes of sleep paralysis or hypnic hallucinations and improvement was sustained at 6 months. It pays to probe for the core experiences or events that patients may be explaining by devising "delusions". Acute, nocturnal-onset, first-time psychopathology warrants inquiry for sleep paralysis and hypnic hallucinations. Sleep-related side-effects of psychotropic medications need to be studied more closely.

Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective, inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology.

Primary hyperaldosteronism is found in up to 13% of patients with hypertension. This article describes a patient with hypokalemia, hypertension, and periodic paralysis that were caused by primary hyperaldosteronism. Plasma aldosterone concentration to plasma renin activity ratio is a common screening test, and adrenal vein sampling can be performed to determine which gland is overproducing aldosterone. Treatment with mineralocorticoid receptor antagonists or adrenalectomy gives similar reductions in BP.

Serratus anterior paralysis can result in winging of the scapula and weakness of arm elevation. The etiology of the condition is injury to the long thoracic nerve. There are many proposed causes of long thoracic nerve injury including acute trauma, Parsonage-Turner syndrome, or viral illness. The long length of the long thoracic nerve makes it prone to compression injury along the chest wall. Most patients recover nerve function with conservative treatment. In those in whom nerve function fails to recover, surgical treatment involving pectoralis major transfer may be beneficial. In this study 9 patients underwent pectoralis major transfer with a fascia lata extension graft. The symptoms of most were improved, with correction of the winging and improved movement in the affected shoulder.

Facial paralysis can have significant functional, psychological and aesthetic concerns that alter the lives of our patients. These effects can be functional, affecting the eye, nose and mouth, or aesthetic, affecting the symmetry of the face and particularly the mimetic function of smile. Several reanimation procedures have been described to address this. In this chapter, we will outline our technique for reanimation utilizing segmental gracilis muscle transplants to the face. These are innervated either by the contralateral normal 7th nerve via a cross face nerve graft, or a different ipsilateral motor where no 7th nerve is available or would not produce the required result. The other ipsilateral motor that we have found extremely effective is the motor nerve to masseter. This can power a segmental gracilis muscle transplant and lead to excursion that is near normal. These techniques will be described in detail.

Patients with Bell's palsy, or idiopathic facial paralysis, present sporadically in the primary care setting. New evidence implicates reactivated herpes simplex virus (HSV) as the etiologic agent in greater than 70% of cases diagnosed as Bell's palsy. Careful evaluation of the patient with facial paralysis, including history, physical examination, and diagnostic assessment, may mandate the expeditious treatment of facial paralysis to prevent faulty nerve regeneration during the recovery period. Using the results of an objective tool for grading resting facial symmetry, symmetry of voluntary movement, and synkinesis can provide a quantitative measurement for decision making. These data are also useful in documenting progression or regression of the patient's facial paralysis. Administration of acyclovir with prednisone improves the recovery of complete facial functioning following an episode of Bell's palsy. During the acute and convalescent stages, the eye on the affected side must be protected until function is restored to the facial nerve. Residual effects of Bell's palsy lasting more than 6 months may indicate another diagnosis and the need to refer the patient to a specialist.

Placental extract has been used as a therapeutic agent with application in various fields of medicine. Placental extract is well known for its effects on wound healing with anti-inflammatory, antiplatelet, and angiogenic effects and is also a biogenic modulator. The present study evaluated the effect of placental extract on wound healing, mouth opening, and postoperative patient discomfort in patients with oral submucous fibrosis treated with fibrotomy with buccal fat pad coverage and coronoidectomy. Ten subjects with oral submucous fibrosis who presented with mouth opening less than 20 mm were enrolled in the present prospective randomized controlled trial to assess the effects of placental extract on the fibrotomy wound covered with a pedicled buccal pad fat (5 patients allocated to the study group, group S and 5 to the control group, group C). The following criteria were used to analyze the postoperative effect of placental extract on fibrotomy wounds compared with that of the controls: subjective assessment of the wound, postoperative discomfort, and postoperative mouth opening assessed at 1, 2, and 4 weeks postoperatively. The average difference in the preoperative and fourth week postoperative mouth opening for group C was 13.8 ± 2.68 mm and was 21.20 ± 2.77 mm in group S. The median calculated for group C was a 15.0-mm increase in mouth opening and was 20.0 mm in group S. The results obtained with topical application of placental extract on fibrotomy wound healing and postoperative mouth opening were superior to those of the control group in whom placental extract was not used.

Foot-and-mouth disease virus (FMDV) is the causative agent of a highly contagious disease and a major concern in animal health worldwide. We have previously reported the use of RNA transcripts mimicking structural domains in the non-coding regions of the FMDV RNA as potent type-I interferon (IFN) inducers showing antiviral effect in vivo, as well as their immunomodulatory properties in combination with an FMD vaccine in mice. Here, we describe the enhancing effect of RNA delivery on the immunogenicity and protection induced by a suboptimal dose of a conventional FMD vaccine in pigs. Animals receiving the RNA developed earlier and higher levels of neutralizing antibodies against homologous and heterologous isolates, compared to those immunized with the vaccine alone, and had higher anti-FMDV titers at late times post-vaccination. RNA delivery also induced higher specific T-cell response and protection levels against FMDV challenge. Peripheral blood mononuclear cells from pigs inoculated with RNA and the vaccine had a higher IFN-γ specific response than those from pigs receiving the vaccine alone. When challenged with FMDV, all three animals immunized with the conventional vaccine developed antibodies to the non-structural viral proteins 3ABC and two of them developed severe signs of disease. In the group receiving the vaccine together with the RNA, two pigs were fully protected while one showed delayed and mild signs of disease. Our results support the immunomodulatory effect of these RNA molecules in natural hosts and suggest their potential use for improvement of FMD vaccines strategies.

Three dendrimeric peptides were synthesized in order to evaluate their immunogenicity and their potential protection against classical swine fever virus (CSFV) in domestic pigs. Construct 1, an optimized version of a previously used dendrimer, had four copies of a B-cell epitope derived from CSFV E2 glycoprotein connected to an also CSFV-derived T-cell epitope through maleimide instead of thioether linkages. Construct 2 was similarly built but included only two copies of the B-cell epitope, and in also bivalent construct 3 the CSFV T-cell epitope was replaced by a previously described one from the 3A protein of foot-and-mouth disease virus (FMDV). Animals were inoculated twice with a 21-day interval and challenged 15days after the second immunization. Clinical signs were recorded daily and ELISA tests were performed to detect antibodies against specific peptide and E2. The neutralising antibody response was assessed 13days after challenge. Despite the change to maleimide connectivity, only partial protection against CSFV was again observed. The best clinical protection was observed in group 3. Animals inoculated with constructs 2 and 3 showed higher anti-peptide humoral response, suggesting that two copies of the B-cell epitope are sufficient or even better than four copies for swine immune recognition. In addition, for construct 3 higher neutralizing antibody titres against CSFV were detected. Our results support the immunogenicity of the CSFV B-cell epitope and the cooperative role of the FMDV 3A T-cell epitope in inducing a neutralising response against CSFV in domestic pigs. This is also the first time that the FMDV T-cell epitope shows effectivity in improving swine immune response against a different virus. Our findings highlight the relevance of dendrimeric peptides as a powerful tool for epitope characterization and antiviral strategies development. Copyright © 2017 Elsevier B.V. All rights reserved.

Although acute idiopathic facial paresis is often labelled "Bell's palsy", historical studies show that Nicolaus Anton Friedreich (1761-1836) from Würzburg was the first physician to describe the typical symptoms of the disorder in 1797, approximately 24 years prior to the paper published by Sir Charles Bell. Diagnostics has now improved to the extent that acute idiopathic facial palsy can more frequently be assigned to etiologies caused by inflammatory disorders. Herpes simplex virus type I and Borrelia burgdorferi are particularly relevant. Underestimation of the degree of paresis is, particularly in children, a drawback of the clinical examination. "Incomplete eyelid closure" is not a reliable indicator of remaining nerve function. For this reason complete electromyography (EMG) is recommended in all cases of severe facial paresis. Since electroneurography does not reliably reflect the degree of denervation present, needle EMG is preferred. The therapy of the facial palsy of unclear etiology is still not well defined. Nevertheless, we recommend that a combined treatment should be used early, at least in patients with disfiguring pareses. Combinations may consist of cortisone, virostatic agents and hemorrheologic substances and possibly antibiotics. Surgical decompression of the facial nerve remains controversial, since positive surgical results lack statistical support. Individual instructions for facial exercises, massage and muscle relaxation can support rehabilitation and possibly reduce the production of pathological synkinesia. Electrical stimulation should not be used. There are a number of possibilities available to reduce the effects of misdirected reinnervation, especially the use of botulinum-A-toxin. However, intensive diagnosis and therapy in the early phase of paresis are decisive in obtaining a favorable outcome. Further refinements in rehabilitation and comparative multicenter controlled studies are still required for future improvements in

The association between congenital facial paralysis and visual development has not been thoroughly studied. Of 27 pediatric cases of congenital facial paralysis, we identified 3 patients who developed amblyopia, a visual acuity decrease caused by abnormal visual development, as comorbidity. These 3 patients had facial paralysis in the periocular region and developed amblyopia on the paralyzed side. They started treatment by wearing an eye patch immediately after diagnosis and before the critical visual developmental period; all patients responded to the treatment. Our findings suggest that the incidence of amblyopia in the cases of congenital facial paralysis, particularly the paralysis in the periocular region, is higher than that in the general pediatric population. Interestingly, 2 of the 3 patients developed anisometropic amblyopia due to the hyperopia of the affected eye, implying that the periocular facial paralysis may have affected the refraction of the eye through yet unspecified mechanisms. Therefore, the physicians who manage facial paralysis should keep this pathology in mind, and when they see pediatric patients with congenital facial paralysis involving the periocular region, they should consult an ophthalmologist as soon as possible. © 2016 S.

To observe clinical effects of "Santong needling" by stages for patients with moderate and severe peripheral facial paralysis (PFP) in the acute period. Sixty patients with moderate and severe PFP were equally and randomly divided into Santong needling group and control group. The patients of the Santong needling group were treated by shallow puncture of Yifeng (TE 17, on the affected side) and Hegu (LI 4, on the healthy side) without needle manipulation in the acute stage ("Qing-tong", mild dredging) , by oblique-penetrative puncture of Dicang (ST 4) to Jiache (ST 6), etc. , and moderate manipulation of needles in the resting stage ("Qiang-tong", stronger dredging) , and by oblique-penetrative puncture of Dicang (ST 4) to Jiache (ST 6), etc., and reinforcing needling manipulation in the recovery stage("Bu-tong", tonifying dredging). The patients of the control group were treated by "Jingjin" (musculotendon) puncture of the same acupoints. The treatment was conducted once daily, 5 times per week for 6 weeks. The 0-3-grade scores of therapeutic effects were evaluated according to the severity of the patients' symptoms and signs (including forehead stripes, palpebral fissure, nasolabial groove, drooping of the mouth angle, bulging cheek-air leak, food residue, dysgeusis, hyperacusi, lacrimation, and orbicularis oculi reflex). The therapeutic effect index = (score of pre-treatment--score of post-treatment)/score of pre-treatment x100% . The patients' life quality scores were assessed by using the World Health Organization Quality of Life (WHOQOL)-BREF questionnaire. After the treatment, the scores of clinical symptoms and signs were significantly decreased in both control and Santong needling groups in comparison with pre-treatment in the same one group (P < 0.05), suggesting an improvement of facial nerve function after 6 weeks' treatment. Of the two 30 patients in the control group and Santong needling group, 11 (36.7%) and 15 (50.0%) were cured, 8 (26.7%) and 9 (30
Facial paralysis has been a recognized condition since Antiquity, and was mentionned by Hippocratus. In the 17th century, in 1687, the Dutch physician Stalpart Van der Wiel rendered a detailed observation. It was, however, Charles Bell who, in 1821, provided the description that specified the role of the facial nerve. Facial nerve surgery began at the end of the 19th century. Three different techniques were used successively: nerve anastomosis, (XI-VII Balance 1895, XII-VII, Korte 1903), myoplasties (Lexer 1908), and suspensions (Stein 1913). Bunnell successfully accomplished the first direct facial nerve repair in the temporal bone, in 1927, and in 1932 Balance and Duel experimented with nerve grafts. Thanks to progress in microsurgical techniques, the first faciofacial anastomosis was realized in 1970 (Smith, Scaramella), and an account of the first microneurovascular muscle transfer published in 1976 by Harii. Treatment of the eyelid paralysis was at the origin of numerous operations beginning in the 1960s; including palpebral spring (Morel Fatio 1962) silicone sling (Arion 1972), upperlid loading with gold plate (Illig 1968), magnets (Muhlbauer 1973) and transfacial nerve grafts (Anderl 1973). By the end of the 20th century, surgeons had at their disposal a wide range of valid techniques for facial nerve surgery, including modernized versions of older techniques.

This study was carried out with a 41-year-old female patient with facial paralysis as a consequence of facial nerve injury during neurosurgery. Low-reactive level laser treatment (LLLT) with a diode laser of 830 nm, 40 mw, continuous wave, spot area 3 mm2, was applied twice a week for 2 weeks, then 1 weekly session following up to 30 sessions, resulting in about 80% improvement of the motor activity.

A 61-year-old man underwent successful percutaneous revascularization of both lower limbs with multiple stent implantations. Paralysis of right lower limb was noticed after completion of procedure when transferring the patient from angiography table. Since hematoma compressing lumbosacral neural plexus could be a fatal complication, computed tomography (CT) image was taken. CT showed bulge of distended bladder compressing stent struts. Following placement of Foley catheter, condition improved and he was subsequently discharged uneventfully.

There are two main methods to treat lower-lip deformity (LLD) in facial paralysis. The first method is surgical intervention on the side of the paralysis, and the second involves denervating the depressor muscles on the healthy side. It is sometimes difficult for patients to ethically accept the denervating healthy tissue; therefore, we performed the T-shape double fascia graft (TSDFG), which reportedly restores symmetry. In this study, we report our experience with TSDFG and evaluation of the outcomes including the patient questionnaires. Two fascia strips from the thigh, 7 × 70 mm in size, were used; one was grafted horizontally at the lower lip to correct the static position, and the other was grafted obliquely at the lateral side by folding and crossing the horizontal fascia. A total of nine patients were treated by this procedure; three procedures were performed individually and six were performed in combination with another static or reanimation procedure. A questionnaire containing a five-point scoring system for facial appearance in multiple situations and other problems was sent to each patient at least 6 months after the surgery. From the physicians' point of view, all patients achieved an improvement in symmetry of the lower lip, particularly when opening of the mouth; however, assessments from the patients demonstrated much less satisfaction. The main reason for the dissatisfaction was the slight bulkiness of the red lip. There was one comment that noted that with more treatment, the expectations were higher, and, as a result, the patient could not admit satisfaction at the end. TSDFG is a simple and effective procedure for LLD; however, slight modifications may be required. In addition, there were some gaps in the perception of the results between the physicians and patients, and we need to consider these when planning to treat LLD.

To raise some problems in the literature of acupuncture and moxibustion for treatment of peripheral facial paralysis and improving suggestions. The CHKD system was used to search out 817 papers of acupuncture for treatment of peripheral facial paralysist, which were reviewed, organized and summarized. In the literature of acupuncture for treatment of peripheral facial paralysis, insufficient understanding in the relative information of clinical data, naming of intractable facial paralysis, differentiation between of the sequelae and complications, the criteria or cproblems in the literature and so on were found. There are some common and representative problems in these papers of acupuncture for treatment of peripheral facial paralysis, which may result in incorrect opinion about the theory and clinical study of acupuncture for treatment of peripheral facial paralysis. Sufficiently considering and resolving the above problems can not only improve the quality of the papers on acupuncture for treatment of peripheral facial paralysis as a whole, but also have active influence on both treatment and diagnosis of this disease.

Suggestions of limb paralysis in highly hypnotically suggestible subjects have been employed to successfully model conversion disorders, revealing similar patterns of brain activation associated with attempted movement of the affected limb. However, previous studies differ with regard to the executive regions involved during involuntary inhibition of the affected limb. This difference may have arisen as previous studies did not control for differences in hypnosis depth between conditions and/or include subjective measures to explore the experience of suggested paralysis. In the current study we employed functional magnetic resonance imaging (fMRI) to examine the functional anatomy of left and right upper limb movements in eight healthy subjects selected for high hypnotic suggestibility during (i) hypnosis (NORMAL) and (ii) attempted movement following additional left upper limb paralysis suggestions (PARALYSIS). Contrast of left upper limb motor function during NORMAL relative to PARALYSIS conditions revealed greater activation of contralateral M1/S1 and ipsilateral cerebellum, consistent with the engagement of these regions in the completion of movements. By contrast, two significant observations were noted in PARALYSIS relative to NORMAL conditions. In conjunction with reports of attempts to move the paralysed limb, greater supplementary motor area (SMA) activation was observed, a finding consistent with the role of SMA in motor intention and planning. The anterior cingulate cortex (ACC, BA 24) was also significantly more active in PARALYSIS relative to NORMAL conditions - suggesting that ACC (BA 24) may be implicated in involuntary, as well as voluntary inhibition of prepotent motor responses.

Thyrotoxic periodic paralysis is rare in Caucasian populations, but affects approximately 2% of East Asians with thyrotoxicosis (13% of males, 0.17% of females). The presentation is characterized by abrupt-onset hypokalemia and profound proximal muscular weakness, and commonly occurs after carbohydrate loading or exercise. To raise awareness of this condition through the description of a typical case of thyrotoxic periodic paralysis; to remind readers that, despite intravascular hypokalemia, total body potassium is normal and that correction must be done with caution; to highlight the differences in treatment compared to familial hypokalemic periodic paralysis. We describe the presentation of a 36-year-old Filipino man with a background history of Graves disease. Over-administration of intravenous potassium was narrowly averted in this case. It may be important to check thyroid function in patients presenting with acute paralysis, especially those of Asian origin. In patients with thyrotoxic periodic paralysis, administration of potassium, with cardiac monitoring and a total dose of <50 mmol, limits the dysrhythmia risk. Patients are likely to benefit from the prescription of non-selective beta-blockers until they become euthyroid. In contrast to familial periodic paralysis, regular oral potassium supplementation is ineffective in thyrotoxic periodic paralysis, and acetazolamide precipitates, rather than prevents, attacks.

Painful infectious mouth conditions are a common presentation to emergency departments. Although self limiting, painful ulcerative lesions and inflamed mucosa can decrease oral intake and can lead to dehydration. Oral analgesia is of limited efficacy and is often refused by the patient. Despite widespread use of oral 2% viscous lidocaine for many years, there is little evidence for its efficacy as an analgesic and in aiding oral intake in children with painful infectious mouth conditions. This study aims to establish the effectiveness of 2% viscous lidocaine in increasing oral intake in these children by comparing it with placebo. This study is a randomised double-blind placebo controlled trial of children between 6 months and 8 years of age with painful infectious mouth conditions defined as gingivostomatitis (herpetic or non herpetic), ulcerative pharyngitis, herpangina and hand foot and mouth disease as assessed by the treating clinician in association with a history of poor oral fluid intake. It will be conducted at a single tertiary paediatric emergency department in Melbourne Australia.20 patients have already been randomised to receive 2% lidocaine or placebo in a pilot study to determine the sample size in a preplanned adaptive design. A further 80 patients will be randomised to receive either 2% lidocaine or placebo. The placebo agent is identical to lidocaine in terms of appearance, flavour and smell. All clinical and research staff involved, patients and their parents will be blinded to treatment allocation.The primary endpoint is the amount of fluid ingested by each child, expressed in ml/kg, within 60 minutes from the time of administration of the study mixture. Secondary endpoints are the proportion of patients ingesting 5 ml/kg and 10 ml/kg at 30 and 60 minutes after drug administration and the incidence of adverse events. Longer term outcomes will include the proportion of patients requiring hospital admission and length of emergency department stay

Laryngeal framework surgery is the current gold standard treatment for unilateral vocal fold paralysis. It provides a permanent solution to glottic insufficiency caused by injury to the recurrent laryngeal nerve. Various modifications to the original Isshiki type I laryngoplasty procedure have been described to improve voice and swallowing outcomes. The success of this procedure is highly dependent on the experience of the surgeon as it epitomizes the intersection of art and science in the field. The following article reviews the evidence, controversies, and complications related to laryngoplasty for unilateral vocal fold paralysis. It also provides a detailed analysis of how and when arytenoid-positioning procedures should be considered, and summarizes the literature on postoperative outcomes. PMID:24883239

This case report presents a patient who developed right shoulder pain following strenuous upper-extremity exercise. Approximately 6 weeks later his pain resolved, he noticed persistent right upper-extremity weakness. He was referred to physical therapy for evaluation and treatment. Physical therapy evaluation revealed isolated serratus anterior muscle paralysis. A long thoracic neuropathy was subsequently confirmed by electromyographic testing. The etiology, pathophysiology, and pathokinesiology of serratus anterior muscle paralysis are reviewed. A case is presented, illustrating how the clinical decision making is based on the pathokinesiology and pathophysiology. The patient was followed over the course of 17 months and has recovered full right shoulder active range of motion. His serratus anterior muscle strength has increased to Good minus, and he reports significantly improved functional use of the upper extremity.

We present in this case report the return to flying duty of a pilot with vocal cord paralysis secondary to removal of a thymoma. We discuss the importance of glottic function as it pertains to the unique aviation environment. We also discuss the anatomy and physiology of the glottis, the evaluation for vocal cord paralysis, and surgical approaches for paralyzed vocal cords. Although the incidence of recurrent laryngeal nerve paralysis is low in the military aviation community, it is important to recognize that its sequelae can be managed so that the aviator may return to flight duties.

Facial palsy is a relatively common condition, from which most cases recover spontaneously. However, each year, there are 127,000 new cases of irreversible facial paralysis. This condition causes aesthetic, functional and psychologically devastating effects in the patients who suffer it. Various reconstructive techniques have been described, but there is no consensus regarding their indication. While these techniques provide results that are not perfect, many of them give a very good aesthetic and functional result, promoting the psychological, social and labour reintegration of these patients. The aim of this article is to describe the indications for which each technique is used, their results and the ideal time when each one should be applied.

The aim was to investigate the efficacy of cortexin and methylprednisolone on recovery in cases of traumatic facial nerve paralysis occurring after facial nerve trauma. The study was performed on 21 healthy rabbits. The buccal branches of the left facial nerves of all the rabbits were pressed, and facial nerve paralysis occurred. The rabbits were randomly divided into three equal groups: 3 mg/day cortexin intramuscularly, 1 mg/kg/day methylprednisolone intramuscularly, and 3 mg/day saline intramuscularly were administered for 10 days in Group I (cortexin group), Group II (methylprednisolone group), and Group III (control group), respectively. Electromyography was performed on the 7th, 14th, and 21st days to evaluate their improvement. Following this, the traumatic buccal branches of the facial nerves of rabbits were extracted and subjected to histopathological examination. There was a significant difference between the cortexin and methylprednisolone groups and the control group in terms of neural fibrotic degeneration, myelin degeneration, axonal degeneration, normal myelin production, and edema. When the cortexin and methylprednisolone groups were compared with each other, there was no significant difference between them, except for an increase in collagen fibers. Cortexin significantly reduced the collagen fiber increase to a greater extent than methylprednisolone. The electromyography findings did not show any significant difference between the groups or within the groups. Our study suggests that cortexin and methylprednisolone are effective for healing traumatic facial nerve paralysis with intact nerve integrity; however, cortexin is unable to cause significant improvement, which is superior to that caused by methylprednisolone.

The analysis of the correlation between bilateral vocal cord paralysis and the occurrence of obstructive sleep apnea syndrome and snoring is presented. The aim of the study was to establish whether the decrease of the air flow in the upper airway in patients with bilateral vocal cord paralysis involves OSAS and/or snoring occurrence and whether arytenoidectomy affects an improvement of breathing parameters measured during sleep. Fourteen patients with bilateral vocal cord paralysis underwent Poly-MESAM examination before and 3 months after arytenoidectomy. They had never complained of snoring before. The Epworth sleepiness scale was used to quantify excessive daytime somnolence. The RDI, DI, mean saturation and percentage of snoring, loud snoring and sleep without snoring were estimated and compared pre- and postoperatively. The results were compared by the Student's t-test for dependent values. No significant differences were shown between the Epworth scores before and after the treatment. The RDI, DI and mean saturation were normal before and after the operation. The percentage of loud snoring decreased and the percentage of sleep without snoring increased significantly after arytenoidectomy in both cases. The mechanism of snoring in patients with vocal cord paralysis seems to be similar to OSAS. The difference consists in the level of flow limitation. On the basis of the results there is no reason to diagnose OSAS and UARS in patients with bilateral vocal cord paralysis. On the other hand, the intensive snoring that occurs after paralysis was significantly reduced as a result of arytenoidectomy.

Excessive ingestion of caffeine can induce hypokalemia, which affects the neuromuscular system and can lead to paralysis. A 24-year-old woman, gravida 3, para 2-0-0-2 at 33 weeks' gestation presented with muscular paralysis and hypokalemia secondary to drinking 6 to 7 L of cola per day with little other oral intake. After potassium replacement and stopping caffeine ingestion, the symptoms resolved quickly. The physiologic changes of pregnancy might potentiate the effect of caffeine on serum potassium concentration.

Vocal fold paralysis is regarded as a sign of other pathologic findings until investigation has proven that there is no lesion to explain the paralysis. We have outlined a cost-effective and time- and labor-efficient method for the clinical evaluation of vocal fold paralysis, including a focused history; vocal capability assessment to find deficits in the function of palate,pharynx, and larynx: and, finally, an intense examination under topical anesthesia to demonstrate these deficits. In essence, it is the endoscopic version of a radiographic study from the skull base through the aortic arch. This method is streamlined as compared with prior protocols for evaluation of vocal fold paralysis, because it directs the necessary further workup according to the likely site of the lesion as indicated by the extended physical examination and can be conducted entirely in the physician's office. Radiographic workup should include CT of the skull base through the upper mediastinum if solely a recurrent nerve paralysis is present; it should include MRI of the skull base if high vagal signs and symptoms are present. If MRI is negative, CT may also be needed for complete evaluation. Neurologic signs that are not all ipsilateral require MRI of the brain and consultation with a neurologist. Esophageal obstruction combined with vocal fold paralysis mandates evaluation via esophagoscopy or an esophagram.

The purpose of this review is to present an up-to-date summary of the signs, diagnosis, treatment, and implications of equine hyperkalemic periodic paralysis. The review encompasses all original articles published between 1986 and early 1993. Hyperkalemic periodic paralysis is the result of a genetic mutation in the skeletal muscle sodium channel gene. It is inherited as an autosomal dominant trait; most affected horses are heterozygotes. The classical signs are muscle fasciculation, spasm, and weakness associated with hyperkalemia. However, these signs are only rarely observed in affected horses. Potential sequelae to attacks are abrasions and involuntary recumbency; these problems are not specific for hyperkalemic periodic paralysis, but they occur more frequently in hyperkalemic periodic paralysis-affected horses. It is also likely that hyperkalemic periodic paralysis results in greater muscle mass. There are suggestions that homozygotes may be more severely affected and show signs of upper respiratory obstruction as foals. The practitioner needs to be aware of the tests for hyperkalemic periodic paralysis, and their limitations, so that he can properly diagnose this condition. The industry has the difficult problem of deciding whether or not testing should be mandatory and the fate of positive horses. Images Figure 2. PMID:8050073

Several surgical procedures have been proposed for the treatment of respiratory distress secondary to bilateral vocal cord paralysis. The aim of all surgical techniques used is to restore a glottic lumen sufficient to guarantee adequate breathing through the natural airway, without tracheotomy and preserving an acceptable phonatory quality. In this study we present our experience from 1998 to 2004 concerning the use of the diode contact laser for a modified Dennis-Kashima posterior endoscopic cordectomy (extended to the false homolateral chord in 3 cases and to the homolateral arytenoid vocal process in 6 cases). 18 patients (15 male, 3 female) were treated; the age range was 35-84 years. The etiology of paralysis varied: iatrogenic post-thyroidectomy and post-thoracic surgery in 5 cases (28%), post-traumatic in 2 cases (11%), secondary to a central lesion in 11 (61%). The operation was carried out with a diode contact laser (60W; 810 nm). Follow-up was 20 months. Dyspnea improved in all patients; the 9 tracheostomized patients were decannulated within 2 months after surgery. Final voice quality was subjectively good in 16 patients (88%). None of patients had any complications after surgery. In conclusion, the endoscopic posterior cordectomy performed by contact diode laser is an effective and reliable method for the treatment of dyspnea secondary to bilateral laryngeal paralysis, guaranteing a sufficient airway without impairing swallowing and maintaining acceptable voice quality.

Breathing mode was objectively determined by monitoring airflow through the mouth, measuring nasal resistance and lip-seal function, and collecting information via questionnaire on the patient's etiology and symptoms of mouth breathing. The expiratory airflow through the mouth was detected with a carbon dioxide sensor for 30 minutes at rest. Fifteen men and 19 women volunteers (mean age, 22.4 +/- 2.5 years) were classified as nasal breathers, complete mouth breathers, or partial mouth breathers based on the mean duration of mouth breathing. Nasal resistance, lip-sealing function, and the subjective symptoms of mouth breathing ascertained by questionnaire were statistically compared by using 1-way and 2-way analysis of variance (ANOVA) and the chi-square test in the breathing groups. Nasal resistance was significantly (P <0.05) greater for the mouth breathers than for the nasal breathers, and significantly (P <0.05) greater for the partial mouth breathers than for the complete mouth breathers. There were no significant differences in the subjective responses to questions about mouth breathing among the 3 groups. Detecting airflow by carbon dioxide sensor can discriminate breathing mode. Degree of nasal resistance and subjective symptoms of mouth breathing do not accurately predict breathing mode.
Cancer treatments may cause dental, mouth, and throat side effects such as changes in taste (dysgeusia), dry mouth (xerostomia), infections, mouth sores, pain or swelling in your mouth (oral mucositis), sensitivity to foods, and swallowing problems.
This paper examines the questions "who is the dry mouth patient and how is the dry mouth patient evaluated"? It reviews the clinical features of dry mouth. It presents current treatment options for dry mouth care.

Laryngomalacia is the most frequent congenital anomaly of airways, and it may cause obstructive sleep apneas. The associated vocal cord paralysis may aggravate the symptoms of upper airway obstruction. In a 14 month old boy severe laryngomalacia and bilateral vocal cord paralysis were diagnosed by flexible bronchoscopy. A sleep study showed a severe obstructive sleep apnoea (OSA). The patient was ventilated at home via the face mask with non invasive mechanical ventilation (CPAP) for a year. The level of pressure had to be set at 7 cm H2O to correct desaturation with an improvement in mean SpO2. On the follow up bronchoscopic examination laryngomalatia was improved, vocal cord paralysis persisted and sleep study revealed significant improvement. In the patient with severe laryngomalatia and bilateral vocal cord paralysis with OSA conservative treatment with CPAP was used instead of a surgical intervention. Non invasive ventilation was used every night, for at least 6 hours, without adverse events. Invasive measurement of transdiaphragmatic pressure is the best way of titrating of CPAP level. This case report suggests the efficacy of noninvasive titrating of CPAP level by the hemoglobin oxygen saturation trend measurement. In case of severe laryngomalatia and associated vocal cord paralysis, followed by OSA non invasive ventilation by nasal CPAP represents an effective and safe alternative to surgery.

Description of a new surgical technique for treating the shoulders of patients with sequelae of obstetric paralysis. Preliminary analysis on the results obtained from this technique. Five consecutive patients underwent the proposed surgical procedure, consisting of arthroscopic anterior joint release followed by transfer of the latissimus dorsi tendon (elongated and reinforced with a homologous tendon graft) to the posterosuperior portion of the greater tubercle, using a single deltopectoral approach. All the patients were reevaluated after a minimum postoperative period of twelve months. The functional assessment was based on the range of motion and the modified Mallet classification system. Statistical analyses were not possible because of the small sample. Overall, passive and active lateral rotations increased, while medial rotation decreased. The other movements (elevation, capacity to place a hand in the mouth and capacity to place a hand behind the neck) had less consistent evolution. The mean modified Mallet score improved by 4.2 points (from 11.4 to 15.6). The latissimus dorsi tendon can be transferred to the posterosuperior portion of the greater tubercle through a single deltopectoral approach when elongated and reinforced with a homologous tendinous graft.

The purpose of the current article is to describe a personalized practice originally conceived as a way to prevent and minimize care-resistant behavior to provide mouth care to older adult with dementia. The original intervention, Managing Oral Hygiene Using Threat Reduction Strategies (MOUTh), matured during the clinical trial study into a relationship-centered intervention with emphasis on developing strategies that support residents behavioral health and staff involved in care. Relationships that were initially pragmatic (i.e., focused on the task of completing mouth care) developed into more personal and responsive relationships that involved deeper engagement between mouth care providers and nursing home (NH) residents. Mouth care was accomplished and completed in a manner enjoyable to NH residents and mouth care providers. The MOUTh intervention may also concurrently affirm the dignity and personhood of the care recipient because of its emphasis on connecting with older adults. PMID:26934969

Ninety-two children, the entire series of paediatric facial reanimation by a single surgeon over thirty years, are presented. The objective is to analyse the incidence and value of secondary revisions for functional and aesthetic refinements following the two main stages of reanimation. The reconstructive strategy varied according to the denervation time, the aetiology, and whether the paralysis was uni- or bilateral, complete or partial. Irrespective of these variables, 89% of the patients required secondary surgery. Post-operative videos were available in seventy-two cases. Four independent observers graded patients' videos using a scale from poor to excellent. The effect of diverse secondary procedures was measured computing a mean-percent-gain score. Statistical differences between treatment groups means were tested by the t-test and one-way ANOVA. Two-thirds of the corrective and ancillary techniques utilized granted significantly higher mean-scores post-secondary surgery. A comparison of pre- and post-operative data found valuable improvements in all three facial zones after secondary surgery. In conclusion, inherent to dynamic procedures is the need for secondary revisions. Secondary surgery builds in the potential of reanimation surgery, effectively augmenting functional faculties and aesthesis.

Burning mouth syndrome (BMS) is a chronic condition that is characterized by burning symptoms of the oral mucosa without obvious clinical examination findings. This syndrome has complex characteristics, but its cause remains largely enigmatic, making treatment and management of patients with BMS difficult. Despite not being accompanied by evident organic changes, BMS can significantly reduce the quality of life for such patients. Therefore, it is incumbent on dental professionals to diagnose and manage patients with BMS as a part of comprehensive care.

Culture change aims to fundamentally improve care provision in a manner consistent with individual preferences. However, few studies of culture change have focused on the quality of daily care, despite the fact that system-wide efforts are important to assure the effectiveness, adoption, and sustainability of person-centered care to meet daily needs. This paper describes a new culture change practice, Mouth Care Without a Battle. The focus on mouth care is predicated on the important association between person-centered support for oral hygiene and quality of life. Mouth Care Without a Battle is a person-centered approach to quality mouth care for persons with cognitive and physical impairment. It was developed by an interdisciplinary team of clinician researchers based on literature review, consultation with experts, environmental scan of existing programs, and testing in nursing homes. Building from the success of Bathing Without a Battle, Mouth Care Without a Battle was evaluated in terms of changed care practices and outcomes, developed into a training program, and packaged for dissemination as a digital video disk (DVD) and website. The development and evaluation of Mouth Care Without a Battle demonstrate attention to the areas necessary to establish the evidence-base for culture change, to ultimately empower and support staff to provide care to achieve quality outcomes. As illustrated in this paper, it is beneficial to build the evidence base for culture change by attending to care processes and outcomes benefiting all residents, ability to implement culture change, and costs of implementation.

Brain mechanisms underlying hysterical conversion symptoms are still poorly known. Recent hypotheses suggested that activation of motor pathways might be suppressed by inhibitory signals based on particular emotional situations. To assess motor and inhibitory brain circuits during conversion paralysis, we designed a go-nogo task while a patient underwent functional magnetic resonance imaging (fMRI). Preparatory activation arose in right motor cortex despite left paralysis, indicating preserved motor intentions, but with concomitant increases in vmPFC regions that normally mediate motivational and affective processing. Failure to execute movement on go trials with the affected left hand was associated with activations in precuneus and ventrolateral frontal gyrus. However, right frontal areas normally subserving inhibition were activated by nogo trials for the right (normal) hand, but not during go trials for the left hand (affected by conversion paralysis). By contrast, a group of healthy controls who were asked to feign paralysis showed similar activation on nogo trials and left-go trials with simulated weakness, suggesting that distinct inhibitory mechanisms are implicated in simulation and conversion paralysis. In the patient, right motor cortex also showed enhanced functional connectivity with the posterior cingulate cortex, precuneus, and vmPFC. These results suggest that conversion symptoms do not act through cognitive inhibitory circuits, but involve selective activations in midline brain regions associated with self-related representations and emotion regulation.

Severe hypokalemia is a potentially life-threatening disorder and is associated with variable degrees of skeletal muscle weakness, even to the point of paralysis. On rare occasions, diaphragmatic paralysis from hypokalemia can lead to respiratory arrest. There may also be decreased motility of smooth muscle, manifesting with ileus or urinary retention. Rarely, severe hypokalemia may result in rhabdomyolysis. Other manifestations of severe hypokalemia include alteration of cardiac tissue excitability and conduction. Hypokalemia can produce electrocardiographic changes such as U waves, T-wave flattening, and arrhythmias, especially if the patient is taking digoxin. Common causes of hypokalemia include extrarenal potassium losses (vomiting and diarrhea) and renal potassium losses (eg, hyperaldosteronism, renal tubular acidosis, severe hyperglycemia, potassium-depleting diuretics) as well as hypokalemia due to potassium shifts (eg, insulin administration, catecholamine excess, familial periodic hypokalemic paralysis, thyrotoxic hypokalemic paralysis). Although the extent of diuretic misuse in professional bodybuilding is unknown, it may be regarded as substantial. Hence, diuretics must always be considered as a cause of hypokalemic paralysis in bodybuilders.

The treatment of long-standing facial paralysis through temporalis muscle transfer has stood the test of time. Herein, we present a modification in temporalis muscle transfer for lower facial reanimation. Instead of the traditional stripping of the temporalis muscle from its origin, its insertion is stripped from the coronoid process through an intraoral approach. The detached fibers were then sutured to a fascia lata graft, which was passed and secured to the orbicularis oris to reanimate the corner of the mouth. The procedure is less extensive and provides a direct “orthodromic” line of pull with good muscular excursion and power. This simple procedure has been applied to 12 consecutive cases with long-standing complete facial paralysis presenting to the Plastic and Reconstructive Surgery Clinic at the Ain-Shams University Hospital over the past 2 years. In addition to symmetry at rest, this easy procedure allowed for good movement of the corner of the mouth with restoration of a balanced smile. PMID:22110814

The aim of this study was to investigate the effects of needle-pricking therapy on peripheral facial paralysis. This study included 162 patients with peripheral facial paralysis, 107 of whom were treated with usual care (conventional and alternative treatments) and 55 of whom were additionally treated with needle-pricking therapy on 3 specific extra-meridian acupuncture points known as 'Samjoong' (Sānchóng in Chinese). We evaluated changes in facial motor functions and sequelae using the Yanagihara and gross House-Brackmann grading systems before and after treatments. Yanagihara score and House-Brackmann grade significantly improved after treatments in both groups. However, the needle-pricking therapy group showed greater improvements in Yanagihara score and House-Brackmann grade than the usual care group. Our results suggest that Samjoong needle-pricking therapy could be applied as an adjunct therapy to usual care for patients with peripheral facial paralysis. © 2014 S. Karger GmbH, Freiburg.

Paralysis or nerve injury associated with fractures of forearm bones fracture is rare and is more common in exposed fractures with large soft-tissue injuries. Ulnar nerve paralysis is a rare condition associated with closed fractures of the forearm. In most cases, the cause of paralysis is nerve contusion, which evolves with neuropraxia. However, nerve lacerations and entrapment at the fracture site always need to be borne in mind. This becomes more important when neuropraxia appears or worsens after reduction of a closed fracture of the forearm has been completed. The importance of diagnosing this injury and differentiating its features lies in the fact that, depending on the type of lesion, different types of management will be chosen.

Ten cases of isolated, complete paralysis of the serratus anterior muscle were diagnosed in young athletes during a three-year period. One patient had recurrent partial paralysis of the serratus anterior muscle, the first such case reported. From studies on cadavera and clinical observations, we concluded that paralysis of the serratus anterior muscle results from a traction injury to the long thoracic nerve of Bell. Since full recovery usually occurs in an average of nine months, surgical methods of treatment should be reserved for patients in whom function fails to return after a two-year period. Non-strenuous use of the involved extremity with avoidance of the precipitating activity, followed by exercises designed to maintain the range of motion of the shoulder and to increase the strength of associated muscles, is advocated for treatment of acute or repetitive injuries to the long thoracic nerve of Bell.

Bell's palsy is defined as an idiopathic peripheral facial nerve paralysis of sudden onset. It affects 11-40 persons per 100,000 per annum. Many patients recover without intervention; however, up to 30% have poor recovery of facial muscle control and experience facial disfigurement. The aim of this study was to make an overview of which pharmacological treatments have been used to improve outcomes. The available evidence from randomized controlled trials shows significant benefit from treating Bell's palsy with corticosteroids but shows no benefit from antivirals.

Twenty patients with periodic paralysis were evaluated and the aspects studied included epidemiological data, clinical manifestations, ancillary tests, treatment and evolution. Sixteen patients had the hypokalemic form (5 familiar, 5 sporadic, 5 thyrotoxic and 1 secondary). No patient with the normokalemic form was detected. Predominance of men was found (14 patients), especially in the cases with hyperthyroidism (5 patients). No thyrotoxic patient was of oriental origin. Only 4 patients had the hyperkalemic form (3 familiar, 1 sporadic). Attacks of paralysis began during the first decade in the hyperkalemic form and up to the third decade in the hypokalemic. In both forms the attacks occurred preferentially in the morning with rest after exercise being the most important precipitating factor. Seventy five percent of the hyperkalemic patients referred brief attacks (< 12 hours). Longer attacks were referred by 43% of the hypokalemic patients. The majority of the attacks manifested with a generalized weakness mainly in legs, and its frequency was variable. Creatinokinase was evaluated in 10 patients and 8 of them had levels that varied from 1.1 to 5 times normal. Electromyography was done in 6 patients and myotonic phenomenon was the only abnormality detected in 2 patients. Carbonic anhydrase inhibitors, especially acetazolamide, were used for prophylactic treatment in 9 patients with good results in all. Although periodic paralysis may be considered a benign disease we found respiratory distress in 5 patients, permanent myopathy in 1, electrocardiographic abnormalities during crises in 4; death during paralysis occurred in 2. Therefore correct diagnosis and immediate treatment are crucial. This study shows that hyperthyroidism is an important cause of periodic paralysis in our country, even in non oriental patients. Hence endocrine investigation is mandatory since this kind of periodic paralysis will only be abated after return to the euthyroid state.

Burning Mouth Syndrome (BMS) is a chronic disorder that predominately affects middle-aged women in the postmenopausal period. The condition is distinguished by burning symptoms of the oral mucosa and the absence of any clinical signs. The etiology of BMS is complex and it includes a variety of factors. Local, systemic and psychological factors such as stress, anxiety and depression are listed among the possible causes of BMS. BMS may sometimes be classified as BMS Type I, II or III. Although this syndrome is not accompanied by evident organic alterations and it does not present health risks, it can significantly reduce the patient's quality of life. This study analyzes the available literature related to BMS, and makes special reference to its therapeutic management. The pages that follow will also discuss the diagnostic criteria that should be respected, etiological factors, and clinical aspects. We used the PubMed database and searched it by using the keywords "burning mouth syndrome", "BMS and review", and "burning mouth and review", in the title or abstract of the publication. BMS treatment usually steers towards the management of the symptoms; however, the specific local factors that could play a significant role in worsening the oral burning sensation should be eradicated. The most widely accepted treatment options that show variable results include tricyclic antidepressants, benzodiazepines and antipsychotic drugs; nevertheless there are other therapies that can also be carried out. Professionals that work in the field of dentistry should formulate standardized symptomatic and diagnostic criteria in order to more easily identify the most effective and reliable strategies in BMS treatment through multidisciplinary research.

Burning mouth syndrome (BMS) is a complex disorder that is characterized by warm or burning sensation in the oral mucosa without changes on physical examination. It occurs more commonly in middle-aged and elderly women and often affects the tip of the tongue, lateral borders, lips, hard and soft palate. This condition is probably of multi-factorial origin, often idiopathic, and its etiopathogensis is unknown. BMS can be classified into two clinical forms namely primary and secondary BMS. As a result, a multidisciplinary approach is required for better control of the symptoms. In addition, psychotherapy and behavioral feedback may also help eliminate the BMS symptoms. PMID:26015707

Burning mouth syndrome (BMS) is an enigmatic, misunderstood, and under-recognized painful condition. Symptoms associated with BMS can be varied, thereby providing a challenge for practitioners and having a negative impact on oral health-related quality of life for patients. Management also remains a challenge for practitioners because it is currently only targeted for symptom relief without a definitive cure. There is an urgent need for further investigations to determine the efficacy of different therapies because this is the only way viable therapeutic options can be established for patients with this chronic and painful syndrome.

Carbonic anhydrase II (CAII) deficiency is an autosomal recessive disorder manifest by osteopetrosis, renal tubular acidosis, and cerebral calcification. Other features include growth failure and mental retardation. Complications of the osteopetrosis include frequent bone fractures, cranial nerve compression, and dental mal-occlusion. A hyper-chloremic metabolic acidosis, sometimes with hypokalemia, occurs due to renal tubular acidosis that may be proximal, distal, or more commonly, the combined type. Such patients may present with global hypotonia, muscle weakness or paralysis. We report a case of CA II deficiency with recurrent attacks of acute paralysis which was misdiagnosed initially as Guillian-Barre syndrome.

The preoperative assessment of the eye in facial paralysis is a critical component of surgical management. The degree of facial nerve paralysis, lacrimal secretion, corneal sensation, and lower eyelid position must be assessed accurately. Upper eyelid loading procedures are standard management of lagophthalmos. Lower eyelid tightening repositions the lower eyelid and helps maintain the aqueous tear film. Eyelid reanimation allows an aesthetic symmetry with blinking and restores protective functions vital to ocular preservation. Patients often have multiple nervous deficits, including corneal anesthesia. Other procedures include tarsorrhaphy, spring implantation, and temporalis muscle transposition; associated complications have rendered them nearly obsolete.

Foreign bodies in the oral cavity and pharynx are commonly encountered in the emergency room and outpatient departments, and the most frequently observed of these foreign bodies are fish bones. Among the possible complications resulting from a pharyngeal foreign body, vocal cord fixation is extremely rare, with only three cases previously reported in the English literature. The mechanisms of vocal cord fixation can be classified into mechanical articular fixation, direct injury of the recurrent laryngeal nerve, or recurrent laryngeal nerve paralysis secondary to inflammation. The case discussed here is different from previous cases. We report a rare case of vocal cord paralysis caused by the venom of a stingray tail in the hypopharynx.

Facial-nerve paralysis is seldom seen and may occur because of a broad spectrum of causes. The most commonly seen cause of facial paralysis is the Bell palsy; iatrogenic causes and tumors are relatively rare. Facial asymmetry, drooling, garbled speech, and difficulty in feeding: all adversely affect the psychosocial conditions of the patients. Fascial and tendon sling procedures may be performed for the static treatment of the unilateral permanent facial paralysis. These techniques are used both for the correction of the asymmetry of the face, especially by providing static support for the corner of the mouth, and to prevent drooling. Microstomia after a sling procedure is not a previously observed complication in the literature. A patient is presented with the surgical management of the complication of microstomia that had risen because of a static treatment of his unilateral facial paralysis via a tendon that passes circularly through his orbicularis oris muscle. Oral rehabilitation thereafter was maintained with the support of dental implants and fixed prosthodontics. The most efficient treatment protocol was decided with an interdisciplinary consultation of the oral and maxillofacial surgeon, the plastic surgeon, and the prosthodontist.

In vitro polydisperse aerosol deposition in three mouth-throat models, namely, the USP (United States Pharmacopeia) mouth-throat (induction port), idealized mouth-throat, and highly idealized mouth-throat, was investigated experimentally. Aerosol particles emitted from two commercial inhalers, Qvar (pMDI) and Turbuhaler (DPI), were used. The in vitro deposition results in these three mouth-throat models were compared with in vivo data available from the literature. For the DPI, mouth-throat deposition was 57.3 +/- 4.5% for the USP mouth-throat, 67.8 +/- 2.2% for the idealized mouth-throat, and 69.3 +/- 1.1% for the highly idealized mouth-throat, which are all relatively close to the in vivo value of 65.8 +/- 10.1%. In contrast, for the pMDI, aerosol deposition in the idealized mouth-throat (25.8 +/- 4.2%) and the highly idealized mouth-throat (24.9 +/- 2.8%) agrees with the in vivo data (29.0 +/- 18.0%) reported in the literature better than that for the USP mouth-throat (12.2 +/- 2.7%). In both cases, the USP mouth-throat gives the lowest deposition among the three mouth-throat models studied. In summary, both the idealized mouth-throat and highly idealized mouth-throat improve the accuracy of predicted mean in vivo deposition in the mouth-throat region. This result hints at the potential applicability of either the idealized mouth-throat or highly idealized mouth-throat as a future USP mouth-throat standard to provide mean value prediction of in vivo mouth-throat deposition.

Rapid detection of infection is critical to the containment and control of contagious pathogens. Passive surveillance, based on the detection of clinical signs through farmers' observations and subsequent veterinarian notification, is the primary means of initially detecting an epizootic and for implementing control measures. The objective of this study was to analyse how the composition and structure of passive surveillance networks may impact epizootic spread and control. Three compositions of passive surveillance network were considered: (i) A veterinarian-based surveillance network composed of farmers and veterinarians (the common passive surveillance network where each veterinarian follows up a group of holdings), (ii) a farmer-based surveillance network composed of farmers only (the farmer plays the same role as in the preceding network as well as that of the veterinarian but his point of view is limited to his animals) and (iii) a hierarchical surveillance network composed of farmers, veterinarians and district-level veterinarian specialists (in case of doubt, the local veterinarian calls the specialist veterinarian). We compared the efficacy of these different network types where actors have successively a structurally wider perspective than the preceding ones using a specific stochastic model for the spread of foot-and-mouth disease (FMD). The model was forced by actual data to generate realistic simulated FMD epizootics in France. Our results show that maintaining the presence of field veterinarians following-up several holdings in breeding areas is fundamental and adding veterinarian specialists to passive surveillance networks could greatly enhance surveillance network efficacy.

Burning mouth syndrome is a debilitating medical condition affecting nearly 1.3 million of Americans. Its common features include a burning painful sensation in the mouth, often associated with dysgeusia and xerostomia, despite normal salivation. Classically, symptoms are better in the morning, worsen during the day and typically subside at night. Its etiology is largely multifactorial, and associated medical conditions may include gastrointestinal, urogenital, psychiatric, neurologic and metabolic disorders, as well as drug reactions. BMS has clear predisposition to peri-/post menopausal females. Its pathophysiology has not been fully elucidated and involves peripheral and central neuropathic pathways. Clinical diagnosis relies on careful history taking, physical examination and laboratory analysis. Treatment is often tedious and is aimed at correction of underlying medical conditions, supportive therapy, and behavioral feedback. Drug therapy with alpha lipoic acid, clonazepam, capsaicin, and antidepressants may provide symptom relief. Psychotherapy may be helpful. Short term follow up data is promising, however, long term prognosis with treatment is lacking. BMS remains an important medical condition which often places a recognizable burden on the patient and health care system and requires appropriate recognition and treatment.

Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. All ethnicities can be affected, but TPP typically presents in men of Asian descent. The most common cause of TPP in thyrotoxicosis is Graves' disease. However, TPP can occur with any form of thyrotoxicosis. Up to our knowledge, very few cases ever reported the relationship between TPP and painless thyroiditis. We herein report a 25-yr-old Korean man who suffered from flaccid paralysis of the lower extremities and numbness of hands. The patient was subsequently diagnosed as having TPP associated with transient thyrotoxicosis due to painless thyroiditis. The paralytic attack did not recur after improving the thyroid function. Therefore, it is necessary that early diagnosis of TPP due to transient thyrotoxicosis is made to administer definite treatment and prevent recurrent paralysis.

A 38-year-old man presented with untreated congenital kyphosis associated with progressive spastic gait. To prevent progression of the spastic paralysis, rigid correction of the severe spinal deformity arising from the congenital kyphosis was performed by one-stage posterior closing-wedge osteotomy, without occurrence of neurological complications. Progression of the paralysis has not been identified for 30 months after the operation and a slight improvement in gait was recognized. The current case is categorized as type I deformity of congenital kyphosis in the upper thoracic spine, which is normally treated surgically before the adolescent growth phase begins.

Bell's Palsy is not synonymous with facial nerve paralysis. While it is a common cause of facial nerve paralysis, it is a diagnosis of exclusion and other causes of facial nerve paralysis should be ruled out by appropriate evaluation and follow-up. A case report is presented of a patient with a facial nerve paralysis, which was initially diagnosed as Bell's Palsy, but which was found to be a poorly differentiated parotid malignancy causing facial nerve paralysis. A review and discussion of Bells Palsy, evaluation and treatment is presented.

Sleep paralysis is one of the lesser-known and more benign forms of parasomnias. The primary or idiopathic form, also called isolated sleep paralysis, is illustrated by showing how patients from different cultures weave the phenomenology of sleep paralysis into their clinical narratives. Clinical case examples are presented of patients from Guinea Bissau, the Netherlands, Morocco, and Surinam with different types of psychopathology, but all accompanied by sleep paralysis. Depending on the meaning given to and etiological interpretations of the sleep paralysis, which is largely culturally determined, patients react to the event in specific ways.

Thyrotoxic hypokalemic periodic paralysis is an uncommon complication of thyrotoxicosis, characterized by attacks of generalized muscular weakness associated with hypokalemia in patients with hyperthyroidism, most frequently with Graves-Basedow disease. Treatment with antithyroid drugs and potassium supplements reversed the symptoms and the episodes of acute muscular weakness did not reappear.

Cervical traction is a frequently used treatment in rehabilitation clinics for cervical spine problems. This modality works, in principle, by decompressing the spinal cord or its nerve roots by applying traction on the cervical spine through a harness placed over the mandible (Olivero et al., Neurosurg Focus 2002;12:ECP1). Previous reports on treatment complications include lumbar radicular discomfort, muscle injury, neck soreness, and posttraction pain (LaBan et al., Arch Phys Med Rehabil 1992;73:295-6; Lee et al., J Biomech Eng 1996;118:597-600). Here, we report the first case of unilateral facial nerve paralysis developed after 4 wks of intermittent cervical traction therapy. Nerve conduction velocity examination revealed a peripheral-type facial nerve paralysis. Symptoms of facial nerve paralysis subsided after prednisolone treatment and suspension of traction therapy. It is suspected that a misplaced or an overstrained harness may have been the cause of facial nerve paralysis in this patient. Possible causes were (1) direct compression by the harness on the right facial nerve near its exit through the stylomastoid foramen; (2) compression of the right external carotid artery by the harness, causing transient ischemic injury at the geniculate ganglion; or (3) coincidental herpes zoster virus infection or idiopathic Bell's palsy involving the facial nerve.

A series of complications caused by enteroviruses, including meningitis, encephalitis, acute flaccid paralysis, acute cardiopulmonary failure, respiratory infection, and myocardial injury have been reported in hand, foot and mouth disease/herpangina (HFMD/HA). However, the complication of diarrhoea caused by enteroviruses has been neglected, and a summary of its clinical features and impact on HFMD/HA is unavailable. We included inpatients with HFMD/HA admitted to the Paediatric Department of Zhujiang Hospital during 2009-2012. We summarised and compared clinical data for cases with and without diarrhoea, and determined enterovirus serotypes by reverse transcriptase polymerase chain reaction and genotyping based on a partial-length fragment of viral protein 1 or the 5'-untranslated region. There were 804 inpatients with HFMD/HA and 28 (3.5%) presented with diarrhoea. Gastrointestinal symptoms were mild in most cases of diarrhoea (82.1%), with high prevalence of no dehydration (82.1%), short duration of diarrhoea (78.6%) and watery stools (75.0%). The prevalence of multi-organ dysfunction syndrome (10.7 vs 0.40%) (p = 0.001), hepatic injury (14.3 vs 3.4%) (p = 0.019), myocardial injury (21.4 vs 6.1%) (p = 0.002) and convulsion (21.4 vs 7.2%) (p = 0.016) was significantly higher in the diarrhoea than no diarrhoea group. There was no significant difference between the two groups regarding prevalence of death, altered consciousness, paralysis, central nervous system involvement, or acute respiratory infection. Most patients with diarrhoea caused by enteroviruses circulating in Guangdong Province in 2009-2012 had mild or moderate gastrointestinal symptoms. Although enterovirus-related diarrhoea caused additional multi-organ dysfunction syndrome, hepatic injury and myocardial injury in children with HFMD/HA, timely intervention efficiently reduced disease severity and improved outcome.

Objectives Mouth breathing causes many serious problems in the paediatric population. It has been maintained that enlarged adenoids are principally responsible for mouth breathing. This study was designed to evaluate whether other mechanical obstacles might predispose the child to mouth breathing. Methods 67 children with ages ranging from 10 to 15 years were studied and grouped into mouth-breathers and nose-breathers. The children first underwent axial CT scans of the brain for which they were originally referred. In addition, they were subjected to a limited coronal CT examination of the paranasal sinuses. Congenital anatomical variations as well as inflammatory changes were assessed. Results 87% of mouth-breathing children had hypertrophied adenoids, 77% had maxillary sinusitis, 74% had pneumatized middle concha, 55% had a deviated nasal septum, 55% had hypertrophied inferior conchae, 45% had ethmoidal sinusitis and 23% showed frontal sinusitis. Such changes were significantly less prevalent in nose-breathers. 12.9% of mouth-breathing children did not have adenoids. Of these children, only 3.3% had one or more congenital or inflammatory change whereas the other 9.6% showed a completely normal CT scan signifying the incidence of habitual non-obstructive mouth breathing. Conclusions It is clear that adenoids have a dominant role in causing mouth breathing. Yet, we recommend that paediatricians should assess other mechanical obstacles if mouth breathing was not corrected after adenoidectomy. Further research should be performed to test the validity of correction of such factors in improving the quality of life of mouth-breathing children. PMID:20089737

The purpose of this review is to provide an up-to-date review of injection laryngoplasty technique and currently available injectable materials in the management of unilateral vocal fold paralysis (UVP). Many new materials are currently available as substances for injection laryngoplasty. These materials have been developed along distinct of lines reasoning that address the inherent shortcomings of the previously available injectable substances, namely, poor tissue biocompatibility and poor persistence within the larynx. Accordingly, the past decade has seen heightened efforts toward developing implants with improved biocompatibility and longevity. The past year has witnessed publications reporting animal studies and, on occasion, human clinical trials involving the intralaryngeal injection of calcium hydroxyl-appetite, autologous fascia, particulate silicone and hyaluronic acid derivatives, and others, for managing glottic insufficiency. In recent years, the application of injection laryngoplasty to unilateral vocal fold paralysis (UVP) has regained popularity. The technique of injection laryngoplasty has several appealing qualities including relative technical ease, low cost, and wide availability in many clinical settings. A growing number of injectable substances have been developed and tested in the clinical setting of glottic insufficiency. When used to manage unilateral vocal fold paralysis, however, injection laryngoplasty has one irrefutable shortcoming: an inability to address posterior glottic insufficiency. Therefore, while injection laryngoplasty technique becomes increasingly popular for vocal fold augmentation in cases vocal fold paresis, atrophy, and scarring, its role in the treatment of UVP should be limited to cases with an appropriate glottal defect. These techniques should be considered as part of a complimentary armamentarium with framework surgery.

The evolutionary history of the vertebrate mouth has long been an intriguing issue in comparative zoology. When the prevertebrate state was considered, the oral structure in adult lancelets (amphioxus) was traditionally referred to because of its general similarity to that of the ammocoete larva of lampreys. The larval mouth in lancelets, however, shows a peculiar developmental mode. Reflecting this, the affinity of the lancelet mouth has long been argued, but is still far from a consensus. The increase in available data from molecular biology, comparative developmental biology, paleontology, and other related fields makes it prudent to discuss morphological homology and homoplasy. Here, we review how the lancelet mouth has been interpreted in the study of evolution of the vertebrate mouth, as well as recent advances in chordate studies. With this background of increased knowledge, our innervation analysis supports the interpretation that the morphological similarity in the oral apparatus between ammocoetes and lancelets is a homoplasy caused by their similar food habits.

Burning mouth syndrome (BMS) is multifactorial in origin which is typically characterized by burning and painful sensation in an oral cavity demonstrating clinically normal mucosa. Although the cause of BMS is not known, a complex association of biological and psychological factors has been identified, suggesting the existence of a multifactorial etiology. As the symptom of oral burning is seen in various pathological conditions, it is essential for a clinician to be aware of how to differentiate between symptom of oral burning and BMS. An interdisciplinary and systematic approach is required for better patient management. The purpose of this study was to provide the practitioner with an understanding of the local, systemic, and psychosocial factors which may be responsible for oral burning associated with BMS, and review of treatment modalities, therefore providing a foundation for diagnosis and treatment of BMS.

Taking into account the number of teeth which are yearly irreversible traumatised during sport activities, the general use of mouthguards would contribute positively to the prevention of dental injuries. Custom-made mouthguards are more comfortable to wear and offer better retention and protection than stock and mouth-formed mouthguards. Different kinds of materials are available on the market for the construction of mouthguards. A polyethylene-polyvinylacetate copolymer (EVA) is the most suitable material. EVA allows the inclusion of hard or soft layers within the mouthguard. The thickness of a mouthguard is important for the reduction of applied forces to teeth: energy absorption capacity increases with material thickness. Increased thickness however, is associated with a reduction of comfort. Therefore, it is important that dentists take the patients' wishes and demands on both comfort and protection into consideration. A description of the clinical and technical method for the construction of a custom made mouthguard is given.
Burning mouth syndrome (glossalgia) is manifested by oral pin and tingling sensations, numbness and even burning and severe pains, more frequently in the tongue. Unpleasant sensations may involve the anterior two thirds of the tongue or be extended to the front part of the hard palate and the mucous membrane of the lower lip. This condition is characterized by "mirror" and "food dominant" symptoms, disordered salivation, dysgeusia, or psychological disorders. The disease shows a chronic course. Its etiology may be multifactorial. There are no universally accepted diagnostic criteria; the diagnosis of glossalgia is made to rule out all other causes. A thorough examination should be conducted to establish a differential diagnosis. Glossalgia occurs primarily in middle-aged and elderly people. Women get sick much more frequently than men of the same age. Glossalgia remains difficult to treat. Continuous symptomatic treatment and follow-up help relieve its symptoms.
According to the International Association for the Study of Pain, burning mouth Syndrome (BMS) is defined as a burning pain in the tongue or other oral mucous membrane in the absence of clinical signs or laboratory findings. The etiology is unknown and presents a challenge for both researchers and clinicians. The management of BMS is still not satisfactory. The prognosis is poor and the burning sensation can last for many years causing a dramatic impact on the patient's quality of life. It is important to distinguish between true BMS and symptomatic burning sensation which occurs when the burning sensation is secondary to a local or systemic pathologic condition. Currently, there are no defined diagnostic criteria for BMS. A diagnosis is usually reached by exclusion of other diseases. This may lead to misdiagnoses, presenting an obstacle to successful treatment.
Burning mouth syndrome is a complex pathology for which there is very little information about the etiology and pathogenesis. This lack of knowledge leaves patients with suboptimal treatments. This article discusses the existing scientific evidence about this disease. Since topical oral use of clonazepam have been shown to be effective and safe to treat some patients suffering with burning mouth syndrome, formulations including clonazepam are included with this article. Compounding topical preparations of clonazepam offers opportunities for compounding pharmacists to be more involved in improving the quality of life of burning mouth syndrome patients.

Pharyngeal tuberculosis is a rare disease, and its commonly reported symptoms include sore throat, dysphagia, and throat discomfort. The dysphagia in pharyngeal tuberculosis cases is not due to pharyngolaryngeal paralysis but due to odynophagia. Herein, we describe the first case of dysphagia caused by pharyngolaryngeal paralysis secondary to pharyngeal tuberculosis. An irregular mass at the right nasopharynx was detected in a 57-year-old female patient, along with dysphagia and hoarseness. She had poor right soft palate elevation, inadequate right velopharyngeal closure, poor constrictor pharyngus muscle contraction, and an immobilized right vocal cord, which collectively indicate right pharyngolaryngeal paralysis. Pathological examination and culture testing revealed pharyngeal tuberculosis. She was diagnosed with pharyngolaryngeal paralysis secondary to pharyngeal tuberculosis. The pharyngolaryngeal paralysis resolved after beginning anti-tuberculous treatment. Right pharyngolaryngeal paralysis was attributed to glossopharyngeal and vagus nerve impairment in the parapharyngeal space. Prior reports indicate that peripheral nerve paralysis, including recurrent laryngeal nerve paralysis caused by tuberculous lymphadenitis, often recovers after anti-tuberculous treatment. Pharyngeal tuberculosis rarely causes dysphagia and hoarseness attributable to pharyngolaryngeal paralysis. The neuropathy may recover after anti-tuberculous treatment. Pharyngeal tuberculosis is a new potential differential diagnosis in pharyngolaryngeal paralysis.

BACKGROUND Bilateral abductor vocal fold paralysis can lead to respiratory distress and dyspnea. OBJECTIVES To assess the efficacy of CO2 laser unilateral posterior cordotomy in cases with bilateral abductor paralysis as regards improvement of dyspnea with preservation of satisfactory voice and swallowing after the operation. METHODS A prospective study was done on 18 patients with bilateral abductor vocal fold paralysis (10 females and 8 males) from November 2010 to December 2012 with their ages ranging from 32 to 64 years. RESULTS All patients showed improvement of dyspnea after the operation, most of the patients suffered from mild to moderate dyspnea in the immediate post-operative period, and two patients needed another intervention to solve it. All the patients had satisfactory results of their voice after the operation, and one patient only suffered from temporary aspiration. CONCLUSION Unilateral CO2 laser posterior cordotomy is an easy and effective procedure to solve the dyspnea after bilateral vocal fold abductor paralysis without aspiration or significant voice alteration.

To identify factors associated with dry mouth. Dry mouth adversely affects oropharyngeal health, particularly in elderly, and can lead to pneumonia. A better understanding of the epidemiology of dry mouth is therefore important in improving treatment strategies and oral health in high-risk elderly patients. We conducted a cross-sectional study involving 383 dependent Japanese elderly individuals (65-84 [n = 167] and ≥85 [n = 216] years) at eight long-term care facilities and hospitals. Thirty-four potential factors associated with dry mouth were examined by multiple logistic regression analysis. The primary outcome was dry mouth, as diagnosed by tongue dorsum moisture. We identified that body mass index and severity of physical disability were identified as a potential factors associated with dry mouth in the super-elderly (≥85 years) group, whereas severity of physical disability, outcome measurement time, high daily water consumption, mouth breathing, use of antidepressants and diuretics, and high frequency of daily brushing (≥2 times per day; Odds ratio: 5.56; 95% Confidence Interval: 1.52-20.00) were associated with dry mouth in the 65- to 84-year-old group. To our knowledge, this is the first study to identify a link between frequency of daily brushing and dry mouth and suggests that tooth brushing should be encouraged in high-risk dependent Japanese elderly (65-84 years), particularly those taking antidepressants and/or diuretics. © 2012 John Wiley & Sons A/S and The Gerodontology Association.

Adenotonsillectomy (T&A) may not completely eliminate sleep-disordered breathing (SDB), and residual SDB can result in progressive worsening of abnormal breathing during sleep. Persistence of mouth breathing post-T&As plays a role in progressive worsening through an increase of upper airway resistance during sleep with secondary impact on orofacial growth. Retrospective study on non-overweight and non-syndromic prepubertal children with SDB treated by T&A with pre- and post-surgery clinical and polysomnographic (PSG) evaluations including systematic monitoring of mouth breathing (initial cohort). All children with mouth breathing were then referred for myofunctional treatment (MFT), with clinical follow-up 6 months later and PSG 1 year post-surgery. Only a limited subgroup followed the recommendations to undergo MFT with subsequent PSG (follow-up subgroup). Sixty-four prepubertal children meeting inclusion criteria for the initial cohort were investigated. There was significant symptomatic improvement in all children post-T&A, but 26 children had residual SDB with an AHI > 1.5 events/hour and 35 children (including the previous 26) had evidence of "mouth breathing" during sleep as defined [minimum of 44 % and a maximum of 100 % of total sleep time, mean 69 ± 11 % "mouth breather" subgroup and mean 4 ± 3.9 %, range 0 and 10.3 % "non-mouth breathers"]. Eighteen children (follow-up cohort), all in the "mouth breathing" group, were investigated at 1 year follow-up with only nine having undergone 6 months of MFT. The non- MFT subjects were significantly worse than the MFT-treated cohort. MFT led to normalization of clinical and PSG findings. Assessment of mouth breathing during sleep should be systematically performed post-T&A and the persistence of mouth breathing should be treated with MFT.

Paresis and paralysis are uncommon problems in sheep but are likely to prompt farmers to seek veterinary advice. A thorough and logical approach can aid in determining the cause of the problem and highlighting the benefit of veterinary involvement. While this may not necessarily alter the prognosis for an individual animal, it can help in formulating preventive measures and avoid the costs – both in economic and in welfare terms – of misdirected treatment. Distinguishing between central and peripheral lesions is most important, as the relative prognoses are markedly different, and this can often be achieved with minimal equipment. This article describes an approach to performing a neurological examination of the ovine trunk and limbs, the ancillary tests available and the common and important causes of paresis and paralysis in sheep.

Unilateral paralysis is rarely reported to be primary presentation of severe hypokalemia. We describe a 24-year-old woman who presented to the emergency department with sudden onset of right-sided weakness. Neurologic examination revealed diminished muscle strength and tendon reflexes over the right limbs. Computed tomography of the brain showed no organic brain lesion. However, laboratory data showed hypokalemia (K+ 2.0 mmol/L) with metabolic acidosis (HCO3 − 19 mmol/L). She needed a total of 260 mmol K+ to achieve complete recovery of muscle strength at a serum K+ level of 3.2 mmol/L and was proved to have distal renal tubular acidosis. Severe hypokalemia must be kept in mind as a cause of acute unilateral paralysis without organic lesions to avoid unnecessary examination and potentially life-threatening complications.

A 57-year-old woman underwent an enucleoresection of her right kidney angiomyolipoma. Two weeks later she was admitted to our hospital because of dyspnea at rest with orthopnea. The chest x-ray showed the elevation of both hemidiaphragms and the measurement of the sniff transdiaphragmatic pressure confirmed the diagnosis of bilateral diaphragmatic paralysis. A diaphragm paralysis can be ascribed to several causes, i.e. trauma, compressive events, inflammations, neuropathies, or it can be idiopathic. In this case, it was very likely that the patient suffered from post-surgery neuralgic amyotrophy. To our knowledge, there are only a few reported cases of neuralgic amyotrophy, also known as Parsonage-Turner Syndrome, which affects only the phrenic nerve as a consequence of a surgery in an anatomically distant site.

Les polymyosites sont des maladies inflammatoires des muscles striés, d’étiologie inconnue. Le déficit musculaire, qui se résume généralement à une fatigabilité, évolue de façon bilatérale, symétrique et non sélective avec prédominance sur les muscles proximaux. L'intensité de la faiblesse musculaire est variable d'un sujet à un autre, de la simple gêne fonctionnelle à un état grabataire. Nous rapportons l'observation d'un cas de polymyosite particulièrement sévère avec paralysie musculaire complète, touchant tous les muscles de l'organisme, d’évolution favorable sous immunoglobulines intraveineuses et nous discutons les facteurs favorisant la paralysie musculaire.

To introduce professor Gao Yuchun's clinical experience and treating characteristics of facial paralysis treated with acupuncture and moxibustion. Professor Gao pays attention to yangming when he selects acupoints for clinical syndrome, and directs acupoints selection based on syndrome differentiation in different levels of jingjin, meridians and zangfu; he praises opposing needling technique and reinforcing the deficiency and reducing the excess highly; the acupuncture manipulation is gentle,shallow and slow for reducing the healthy side and reinforcing the affected side, and through losing its excess to complement its deficiency; besides, he stresses needle retaining time and distinguishes reinforcing and reducing. Facial paralysis is treated with key factors such as acupoints selecting based on yangming, acupuncture manipulation, needle retaining time, etc. And the spleen and stomach is fine and good at transportation and transformation; the meridians is harmonious; the qi and blood is smooth. The clinical efficacy is enhanced finally.

Sleep paralysis (SP) is a common parasomnia. The diagnostic criteria for SP, as reported in the International Classification of Sleep Disorders, are essentially clinical, as electroencephalography (EEG)-polysomnography (PSG) is not mandatory. We describe a subject whose sleep-related events fulfilled the diagnostic criteria for SP, even though her visual hallucinations were elementary, repetitive and stereotyped, thus differing from those usually reported by patients with SP. Video/EEG-PSG documented the focal epileptic nature of the SP-like episodes.

An isolated paralysis of the radial nerve in a newborn was reported. The displaced growth of the histologically proved angioleiomyoma caused a circumferential compression with subsequent atrophy of the nerve (Fig. 4). During operative treatment of the tumor, the damaged part of the nerve was resected, too. In a second stage the defect in the nerve was closed by suralis grafts. Possibly due to scar adhesions a good result was not obtained.

To explore the clinical features of hypokalemic periodic paralysis, and compare clinical features of primary group with those of thyrotoxicosis secondary group. Clinical data of 44 patients with hypokalemic periodic paralysis in Peking University First Hospital from 1996 December to 2008 December were retrospectively analyzed. There were 22 patients in primary group, and 22 in thyrotoxicosis group. Identical clinical features of both the groups: (1)It had a predilection in young men. (2)Main symptoms were limb movement disorder and fatigue, and paralysis recurrent attacked in most patients. (3) 40.9% to 68.2% patients had obvious incentives, and the common ones were a heavy meal, sweet drinks, or strenuous exercise. (4) Serum potassium levels of the two groups were obviously lower than the normal range. (5)In 20% patients of primary group and 25% patients of thyrotoxicosis secondary group, CK levels were higher than normal, while LDH and HBDH levels were normal. (6)The doses of potassium replishment were not correlated to serum potassium levels at the onset. Different clinical features of the two groups: (1) Patients of thyrotoxicosis group had hypermetabolism symptoms and thyroid dysfunction. Patients of primary group had no hypermetabolism symptoms, and all of them were euthyroid. (2)Serum potassium levels of thyrotoxicosis secondary group were lower than those of primary group significantly [(2.25 +/- 0.67) vs (2.78 +/- 0.49) mmol/L, P=0.007]. (3) Hyperkalemia is easier than primary group to rebound in thyrotoxicosis secondary group, after replenishment of potassium. Hypokalemic periodic paralysis has its clinical features, and patients with early diagnosis and replenishment of potassium in time have good prognosis. The doses of potassium replenishment are not determined by serum potassium levels at the onset. Hyperkalemia is easier to rebound in thyrotoxicosis secondary group after replenishment of potassium, serum potassium levels should be monitored closely

Bilateral facial palsy is a rare clinical entity caused by myriad disparate conditions requiring different treatment paradigms. Lyme disease, Guillain-Barré syndrome, and leukemia are several examples. In this article, the authors describe the cause, the initial diagnostic approach, and the management of long-term sequelae of bilateral paralysis that has evolved in the authors' center over the past 13 years. A chart review was performed to identify all patients diagnosed with bilateral paralysis at the authors' center between January of 2002 and January of 2015. Demographics, signs and symptoms, diagnosis, initial medical treatment, interventions for facial reanimation, and outcomes were reviewed. Of the 2471 patients seen at the authors' center, 68 patients (3 percent) with bilateral facial paralysis were identified. Ten patients (15 percent) presented with bilateral facial paralysis caused by Lyme disease, nine (13 percent) with Möbius syndrome, nine (13 percent) with neurofibromatosis type 2, five (7 percent) with bilateral facial palsy caused by brain tumor, four (6 percent) with Melkersson-Rosenthal syndrome, three (4 percent) with bilateral temporal bone fractures, two (3 percent) with Guillain-Barré syndrome, one (2 percent) with central nervous system lymphoma, one (2 percent) with human immunodeficiency virus infection, and 24 (35 percent) with presumed Bell palsy. Treatment included pharmacologic therapy, physical therapy, chemodenervation, and surgical interventions. Bilateral facial palsy is a rare medical condition, and treatment often requires a multidisciplinary approach. The authors outline diagnostic and therapeutic algorithms of a tertiary care center to provide clinicians with a systematic approach to managing these complicated patients.

After studying this article, the participant should be able to: 1. Identify all potential points of radial nerve compression and other likely causes of radial nerve injury. 2. Accurately diagnose both surgical and nonsurgical causes of radial nerve paralysis. 3. Define a safe and effective approach to the surgical release and reconstruction of the radial nerve. Radial nerve paralysis, which can result from a complex humerus fracture, direct nerve trauma, compressive neuropathies, neuritis, or (rarely) from malignant tumor formation, has been reported throughout the literature, with some controversy regarding its diagnosis and management. The appropriate management of any radial nerve palsy depends primarily on an accurate determination of its cause, severity, duration, and level of involvement. The radial nerve can be injured as proximally as the brachial plexus or as distally as the posterior interosseous or radial sensory nerve. This article reviews the etiology, prognosis, and various treatments available for radial nerve paralysis. It also provides a new classification system and treatment algorithm to assist in the management of patients with radial nerve palsies, and it offers a simple, five-step approach to radial nerve release in the forearm.

Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism characterized by episodes of muscle weakness and hypokalemia. TPP is typically present in young Asian men, female, and non-Asian ethnic group can also be affected. TPP is a curable cause of hypokalemic periodic paralysis, can often be the first manifestation of thyrotoxicosis. Factors such as high carbohydrate diet, strenuous exercise, emotional stress, and steroid can precipitate an attack of TPP. The presence of both hypokalemia and elevated level of thyroxine (T4) and triiodothyronine (T3) are important diagnostic features during the acute episode. Treatment of TPP involves two steps, immediate action to reverse the paralysis by correction of hypokalemia followed by measures to prevent future attacks by restoration of a euthyroid state. We report a first case of TPP, which was delayed to diagnose, from our hospital due to Graves’ disease in Asian man who present with second episode of paralytic attack before the diagnosis was made which is also unusual as attacks were not frequent.

Recent research results show the recognition rates of all kinds mouth-shape recognition systems are not high enough because of the improper feature selection and extraction for mouth-shape images and the false classification for those features on the boundary of different categories. This paper presents a statistical approach, called CPMSR, for mouth-shape recognition at the phoneme level. The feature-extracting module for this approach is based on research results of phonetics and personal investigation at a deaf school. The analyzing module employs Support Vector Machine (SVM) technique, which is a useful tool dealing with boundary points problem. With these improvements our experiment achieved the satisfactory recognition rate of over 90% for 5 vowels and 24 consonants' mouth-shapes.

The purpose of this study was to determine the factors affecting institutionalized older peoples' self-perceived dry mouth. This cross-sectional study was conducted on elderly residents at 22 long-term care facilities. A total of 165 questionnaires were returned from 13 senior citizen welfare institutions (SCWIs) and nine nursing homes. Multiple logistic regression analysis was used to analyze the data obtained. The results showed that the type of long-term care (LTC) facility, regular oral examinations, wearing dentures, and the ability to chew sticky foods affected self-perceived dry mouth. This study determined an association between the type of LTC facility where the participants lived and self-perceived dry mouth. The results indicated the importance of providing oral care in order to improve and prevent dry mouth among institutionalized older people living in SCWIs who do not undergo regular oral examinations, wear dentures, and have difficulty chewing sticky foods.

Oral submucous fibrosis (OSMF) is a chronic inflammatory disease resulting in progressive juxtaepithelial fibrosis of the oral soft tissues and can cause increasing difficulty in mastication, swallowing, speaking, and mouth opening. The treatment of severe trismus requires a combination of surgical release and physiotherapy. Often physiotherapy alone can modify tissue remodeling in OSMF to increase oral opening. This article describes the fabrication and use of a new mouth-exercising device that helps the patient to squeeze/stretch the cheek mucosa to increase elasticity. The device can be used as a sole treatment modality or can be used in association with pharmacological and surgical treatment modalities for OSMF. Improvement in mouth opening was observed in four OSMF patients treated with a mouth-exercising device for 6 months as a sole treatment modality. © 2012 by the American College of Prosthodontists.

Enterovirus 96 (EV-96) is a recently described member of the species Enterovirus C and is associated with paralysis and myelitis. In this study, using metagenomic sequencing, we identified a new enterovirus 96 strain (EV-96-SZ/GD/CHN/2014) as the sole pathogen causing hand, foot, and mouth disease (HFMD). A genomic comparison showed that EV-96-SZ/GD/CHN/2014 is most similar to the EV-96-05517 strain (85% identity), which has also been detected in Guangdong Province. This is the first time that metagenomic sequencing has been used to identify an EV-96 strain shown to be associated with HFMD.

Bars and subaqueous levees often form at river mouths due to high sediment availability. Once these deposits emerge and develop into islands, they become important elements of the coastal landscape, hosting rich ecosystems. Sea level rise and sediment starvation are jeopardizing these landforms, motivating a thorough analysis of the mechanisms responsible for their formation and evolution. Here we present recent studies on the dynamics of mouth bars and subaqueous levees. The review encompasses both hydrodynamic and morphological results. We first analyze the hydrodynamics of the water jet exiting a river mouth. We then show how this dynamics coupled to sediment transport leads to the formation of mouth bars and levees. Specifically, we discuss the role of sediment eddy diffusivity and potential vorticity on sediment redistribution and related deposits. The effect of waves, tides, sediment characteristics, and vegetation on river mouth deposits is included in our analysis, thus accounting for the inherent complexity of the coastal environment where these landforms are common. Based on the results presented herein, we discuss in detail how river mouth deposits can be used to build new land or restore deltaic shorelines threatened by erosion.

We display the study performed to a female patient affected of laryngeal paralysis to become, based in clinical and radiologic criteria, to diagnose her cerebellar atrophy. We justify our work because of how infrequently this illness heredodegenerative of the central nervous system begins with cranial pairs paralysis. We emphasize the importance that the new methods of explorations specially TAC and IRM, have to guess the possible etiologies of central originated paralysis.

Foot-and-mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals. The disease was initially described in the 16th century and was the first animal pathogen identified as a virus. Recent FMD outbreaks in developed countries and their significant economic impact have increased the concern of governments worldwide. This review describes the reemergence of FMD in developed countries that had been disease free for many years and the effect that this has had on disease control strategies. The etiologic agent, FMD virus (FMDV), a member of the Picornaviridae family, is examined in detail at the genetic, structural, and biochemical levels and in terms of its antigenic diversity. The virus replication cycle, including virus-receptor interactions as well as unique aspects of virus translation and shutoff of host macromolecular synthesis, is discussed. This information has been the basis for the development of improved protocols to rapidly identify disease outbreaks, to differentiate vaccinated from infected animals, and to begin to identify and test novel vaccine candidates. Furthermore, this knowledge, coupled with the ability to manipulate FMDV genomes at the molecular level, has provided the framework for examination of disease pathogenesis and the development of a more complete understanding of the virus and host factors involved.

Thyrotoxic hypokalemic periodic paralysis is an uncommon disorder characterized by elevated thyroid hormone, muscle weakness or paralysis, and intracellular shifts of potassium leading to hypokalemia. This article presents a case of thyrotoxic hypokalemic periodic paralysis in a 22-year old Hispanic man with nonfamilial thyrotoxic hypokalemic periodic paralysis triggered by a high carbohydrate diet. Laboratory studies showed elevated thyroid hormone, decreased thyroid-stimulating hormone, and hypokalemia. Rapid reduction in thyroid hormone levels by giving antithyroid drugs such as propylthiouracil and prompt potassium therapy with frequent measurements of serum potassium levels during therapy to avoid catastrophic hyperkalemia when potassium starts to shift back from intracellular to extracellular compartments can lead to successful outcome.

Ticks are obligate haematophagous ectoparasites of various animals, including humans, and are abundant in temperate and tropical zones around the world. They are the most important vectors for the pathogens causing disease in livestock and second only to mosquitoes as vectors of pathogens causing human disease. Ticks are formidable arachnids, capable of not only transmitting the pathogens involved in some infectious diseases but also of inducing allergies and causing toxicoses and paralysis, with possible fatal outcomes for the host. This review focuses on tick paralysis, the role of the Australian paralysis tick Ixodes holocyclus, and the role of toxin molecules from this species in causing paralysis in the host. PMID:21396246

The quantitative dose requirements for induction of paralysis by BSA in mice has been the subject of further study. Parallel studies have been made with lysozyme, ovalbumin, diphtheria toxoid and ribonuclease, in which similar paralysing and immunizing procedures were used, and similar direct binding tests applied to measurement of the response. In normal adults all the antigens tested induced high-zone paralysis and concomitant immunization, but BSA alone induced low-zone paralysis. With irradiation, with courses of injection commencing at birth, and with paralysis-maintaining treatment, all the antigens tested induced paralysis in a zone quantitatively similar to the low zone detectable in normal adults with BSA. Neither irradiation, treatment with cortisol, nor thymectomy affected the rate of induction of paralysis in the low zone. On the other hand the minimum dose required for immunization varied markedly from one antigen to another. The ability of BSA to induce low-zone paralysis in normal adults can, therefore, be attributed to the failure of low doses of this antigen to immunize. The consistency of paralysis threshold, in contrast to the variability for immunization, is interpreted as evidence of an additional step of complexity involved in immunization that is not required for paralysis.

In a cross-sectional study of the patterns of isolated sleep paralysis among 164 Nigerian medical students, 26.1% admitted having experienced this phenomenon. About 31% of the females and 20% of the males had had this experience. Of those with sleep paralysis, 32.6% had hypnogenic hallucinations during the episode, mainly visual. Sleep paralysis was not significantly associated with psychosocial distress or differences in personality profile. Although the rate differs across cultures, the myths associated with sleep paralysis are similar.

To determine lifetime prevalence rates of sleep paralysis. Keyword term searches using "sleep paralysis", "isolated sleep paralysis", or "parasomnia not otherwise specified" were conducted using MEDLINE (1950-present) and PsychINFO (1872-present). English and Spanish language abstracts were reviewed, as were reference lists of identified articles. Thirty five studies that reported lifetime sleep paralysis rates and described both the assessment procedures and sample utilized were selected. Weighted percentages were calculated for each study and, when possible, for each reported subsample. Aggregating across studies (total N=36,533), 7.6% of the general population, 28.3% of students, and 31.9% of psychiatric patients experienced at least one episode of sleep paralysis. Of the psychiatric patients with panic disorder, 34.6% reported lifetime sleep paralysis. Results also suggested that minorities experience lifetime sleep paralysis at higher rates than Caucasians. Sleep paralysis is relatively common in the general population and more frequent in students and psychiatric patients. Given these prevalence rates, sleep paralysis should be assessed more regularly and uniformly in order to determine its impact on individual functioning and better articulate its relation to psychiatric and other medical conditions.

The diagnostic process of facial paralysis requires qualitative assessment for the classification and treatment planning. This result is inconsistent assessment that potential affect treatment planning. We developed a facial-paralysis diagnostic system based on 3D reconstruction of RGB and depth data using a standard structured-light camera - Kinect 360 - and implementation of Active Appearance Models (AAM). We also proposed a quantitative assessment for facial paralysis based on triangular model. In this paper, we report on the design and development process, including preliminary experimental results. Our preliminary experimental results demonstrate the feasibility of our quantitative assessment system to diagnose facial paralysis.

Diaphragmatic paralysis in newborns is related to brachial plexus palsy. It can be overlooked if thorough examination isn't done. We present a two-weeks-old baby with a birth weight of 3800 grams who had a left-sided brachial plexus palsy and torticollis with an undiagnosed left diaphragmatic paralysis even though he was examined by different physicians several times. The role of physical examination, the chest x-rays of patients with brachial paralysis and the treatment modalities of diaphragmatic paralysis due to obstetrical factors are discussed.

To estimate the prevalence and causes of functional paralysis in the United States. We used the 2013 US Paralysis Prevalence & Health Disparities Survey to estimate the prevalence of paralysis, its causes, associated sociodemographic characteristics, and health effects among this population. Nearly 5.4 million persons live with paralysis. Most persons with paralysis were younger than 65 years (72.1%), female (51.7%), White (71.4%), high school graduates (64.8%), married or living with a partner (47.4%), and unable to work (41.8%). Stroke is the leading cause of paralysis, affecting 33.7% of the population with paralysis, followed by spinal cord injury (27.3%), multiple sclerosis (18.6%), and cerebral palsy (8.3%). According to the functional definition, persons living with paralysis represent a large segment of the US population, and two thirds of them are between ages 18 and 64 years. Targeted health promotion that uses inclusion strategies to account for functional limitations related to paralysis can be undertaken in partnership with state and local health departments.

Bilateral traumatic facial paralysis is a very rare clinical condition. Loss of taste sensation, associated with bilateral traumatic paralysis, is even rarer and has not been well described in the literature. In this report, a 23-year old male, who developed bilateral facial paralysis with loss of taste sensation and hearing impairment, following a motor vehicle accident, is presented. He had initially presented with unconsciousness for about 2 hours after he sustained closed head injury after a motor vehicle accident. Initial Computed Tomography (CT) scans revealed a small epidural hematoma, right temporal bone fracture and air densities around the basal cistern. On the 4th day after trauma, he was noted to have incomplete closure of both eyes and was feeling difficulty with chewing and drooling of saliva. Electrodiagnostic testing confirmed the diagnosis of bilateral facial paralysis-House-Brackmann (HB) grade V. Electroneuronography (ENoG) showed degeneration of 90% nerve fibres bilaterally. The high-resolution CT scans showed bilateral temporal bone fractures. At 3 months of follow-up, the patient had partial recovery of facial nerve function bilaterally and improvement in HB classification to grade III and ENoG of 60% was observed.

To search for an effective therapy for the acute stage of peripheral facial paralysis. One hundred and twenty cases of facial paralysis patients were randomly divided into an observation group and a control group, 60 cases in each group. Both groups were treated with routine medication, and the observation group was treated with shallow needling combined with acupoint application using self-made "acupoint application formula for facial paralysis" on the basis of the routine medication. The acupoints of Yifeng (TE 17), Wangu (GB 12), Dicang (ST 4), Jiache (ST 6), Yangbai (GB 14), Taiyang (EX-HN 5), Qianzheng (EX-HN 17), Cuanzhu (BL 2) in affected side and Hegu (LI 4) in healthy side were selected as main acupoints for shallow needling, and Qianzheng (EX-HN 17), Dicang (ST 4), Yangbai (GB 14) and Wangu (GB 12), or Jiache (ST 6), Taiyang (EX-HN 5), Quanliao (SI 18) and Yifeng (TE 17) were selected for acupoint application. The cure rate and the course of cured patients in both groups were compared. The cure rate of 88.3% (53/60) in observation group was superior to that of 66.7% (40/60) in control group (P < 0.01). The course of cured patients in observation group was obviously shorter than that of control group (P < 0.01). On the basis of routine medication, shallow needling combined with acupoint application can improve the therapeutic effect and shorten the course for acute stage of peripheral facial paralysis.

To measure the attentional distraction to the facial paralysis deformity using eye-tracking, and to distinguish between attention paid to the upper and lower facial divisions in patients with complete paralysis. We hypothesized that features affected by the paralysis deformity would distract the casual observer, leading to an altered pattern of facial attention as compared to normals. Randomized controlled experiment. Sixty casual observers viewed images of paralyzed faces (House-Brackmann [HB] IV-VI) and normal faces smiling and in repose. The SMI iView X RED (SensoMotoric, Inc., Boston, MA) eye-gaze tracker recorded eye movements of observers gazing on the faces. Fixation durations for predefined areas of interest were analyzed using three separate multivariate analyses. Casual observers gazing on both paralyzed and normal faces directed the majority of their attention to the central triangle (CT) region. Significant differences occurred in the distribution of attention among individual features in the CT and to individual sides of the face. Observers directed more attention to the mouth of paralyzed faces, smiling (analysis of variance [ANOVA] > F 0.0001) and in repose (ANOVA > F 0.0000). Attention was asymmetrically distributed between the two halves of paralyzed faces (paralyzed smiling minus normal smiling P > |z| 0.000). Casual observers directed attention in a measurably different way when gazing on paralyzed faces as compared to normal faces, a finding exacerbated with smiling. These findings help explain society's perceptions of attractiveness and affect display that differ for paralyzed and normal faces and can be used to direct our reconstructive efforts.

Incomplete facial paralysis occurs in about a third of patients with Bell's palsy. Although their faces are symmetrical at rest, when they smile they have varying degrees of disfigurement. Currently, cross-face nerve grafting is one of the most useful techniques for reanimation. Transfer of the masseteric nerve, although widely used for complete paralysis, has not to our knowledge been reported for incomplete palsy. Between December 2008 and November 2013, we reanimated the faces of 9 patients (2 men and 7 women) with incomplete unilateral facial paralysis with transposition of the masseteric nerve. Sex, age at operation, cause of paralysis, duration of denervation, recipient nerves used, and duration of follow-up were recorded. Commissural excursion, velocity, and patients' satisfaction were evaluated with the FACIAL CLIMA and a questionnaire, respectively. The mean (SD) age at operation was 39 (±6) years and the duration of denervation was 29 (±19) months. There were no complications that required further intervention. Duration of follow-up ranged from 6-26 months. FACIAL CLIMA showed improvement in both commissural excursion and velocity of more than two thirds in 6 patients, more than one half in 2 patients and less than one half in one. Qualitative evaluation showed a slight or pronounced improvement in 7/9 patients. The masseteric nerve is a reliable alternative for reanimation of the smile in patients with incomplete facial paralysis. Its main advantages include its consistent anatomy, a one-stage operation, and low morbidity at the donor site. Copyright © 2015 The British Association of Oral and Maxillofacial Surgeons.

To observe therapeutic effects of different acupuncture methods for recovery of mimetic function in the patient of spontaneous facial paralysis. One hundred and thirty-four cases of facial paralysis were randomly divided into a mimetic muscle acupuncture group (mimetic muscle group, n = 79) and a routine acupoint group (n = 55). The mimetic muscle group were treated by encircling needling frontal belly of epicranial muscle, orbicular muscle of eye, orbicular muscle of mouth and buccinator muscle, and the routine acupoint group with acupuncture at Dicang (ST 4), Jiache (ST 6), Yangbai (GB 14), Sibai (ST 2), Cuanzhu (BL 2), etc. on the affected side. Their therapeutic effects were compared after they were treated for 2 courses. The effective rate and the good rate were 94.9% and 92.4% in the mimetic muscle group and 70.9% and 52.7% in the routine acupoint group, respectively, with a significant difference between the two groups (P < 0.05). The therapeutic effect of needling the mimetic muscle on spontaneous facial paralysis is superior to that of the routine acupuncture therapy.

Seventeen cases of late ulnar paralysis treated by neurolysis-transposition are reported. The clinical characteristics of these paralyses are emphasized: very prolonged symptom free interval, rapid onset and severe involvement. Ulnar transposition was most often done subcutaneously. Cubitus valgus and definite nerve compression proximal to the arcade of the flexor carpi ulnaris muscle are almost always present. The results as regards the neuropathy are undependable: no patient is completely cured and only half are improved. An anatomical study of the nerve path shows the essential role, in the compression of the nerve, of the muscular arcade of the flexor carpi ulnaris muscle which acts in a way similar to the bridge of a violin. Hence, opening it longitudinally is the principal step of neurolysis. This should be routine before the first signs of neuropathy occur in an elbow whose axis is out of alignment as a sequela of a childhood injury.

Severe hypokalemia can be a potentially life-threatening disorder and is associated with variable degrees of skeletal muscle weakness. We report a case of severe hypokalemic paralysis and rhabdomyolysis in a 28-year-old bodybuilder. He was admitted to the emergency room due to progressive paralysis in both lower extremities, which had begun 12 hours earlier. He was a bodybuilder trainer and had participated in a regional competition 5 days earlier. He went on a binge, consuming large amounts of carbohydrates over 4 days, resulting in a gain of 10 kg in weight. He had no family history of paralysis and this was his first attack. He strongly denied drug abuse, such as anabolic steroids, thyroid and growth hormone, and diuretics. Neurological examinations revealed symmetrical flaccid paralysis in his lower extremities, but the patient was alert and his sensory system was intact. His initial serum potassium and phosphate level was 1.8 mmol/L and 1.4 mg/dL, respectively. The calculated transtubular potassium gradient (TTKG) was 2.02. His thyroid function was normal. Serum potassium levels increased to 3.8 mmol/L with intravenous infusion of about 50 mmol of potassium chloride over 20 hours. His muscular symptoms improved progressively and he was discharged from the hospital 7 days after admission on foot. He was followed in our outpatient clinic, without recurrence. Physicians should keep in mind that large intakes of food during short periods can provoke hypokalemic paralysis and rhabdomyolysis, especially in bodybuilders.

Patients with motor conversion disorder are frequently seen in neurological departments. Long term prognosis is usually considered to be good, although earlier research has been somewhat unsystematic and mostly retrospective. This study follows a well investigated sample of patients for two to five years and attempts to identify predictors associated with prognosis. Thirty patients with a recent onset of motor conversion disorder were assessed for key psychiatric and demographic variables. They were reassessed two to five years later. Nineteen patients had recovered completely and eight patients had improved, while only three patients were unchanged or worse. Contrary to other follow-up studies none of the patients received a rediagnosis of neurological disease. The presence of a personality disorder, concomitant somatic disease, and low DSM-IV axis V score proved to be associated with poor outcome. The results of this study stresses the need for careful and well-conducted neurological and psychiatric assessments in patients with psychogenic paralyses, bearing in mind the substantial possibility for coinciding illnesses. If this is ensured, it appears that the risk of subsequent neurological rediagnosis is negligible.

Thyrotoxic periodic paralysis is a reversible metabolic disorder that is characterized by acute muscle weakness and hypokalemia. It predominantly affects males of Asian descent. We describe the youngest such patient yet reported, a 13-year-old Asian male with a history of transient attacks of weakness who presented to our emergency department with weakness in his extremities and mild tachycardia. Laboratory test results initially revealed marked hypokalemia and later confirmed associated hyperthyroidism. Correction of the hypokalemia reversed the patient's weakness in the emergency department.

Studies have reported that rinsing the mouth with a carbohydrate (CHO) solution improves cycling time-trial performance compared with rinsing with a placebo solution. However, no studies have compared the effect of mouth rinsing with a no-mouth-rinse control condition. The aim of this study was to compare the effects of a CHO mouth rinse with those of a placebo rinse and a no-rinse condition. Ten male cyclists completed three 1,000-kJ cycling time trials in a randomized, counterbalanced order. At every 12.5% of the time trial completed, participants were required to rinse their mouths for 5 s with either a 6.4% maltodextrin solution (CHO), water (WA), or no solution (CON). Heart rate and ratings of perceived exertion (RPE) were recorded every 25% of the time trial completed. Time to completion was faster in both CHO (65.7 ± 11.07 min) and CON (67.6 ± 12.68 min) than in WA (69.4 ± 13.81 min; p = .013 and p = .042, respectively). The difference between CHO and CON approached significance (p = .086). There were no differences in heart rate or RPE between any conditions. In summary, repeated mouth rinsing with water results in decreased performance relative to not rinsing at all. Adding CHO to the rinse solution appears to oppose this fall in performance, possibly providing additional benefits to performance compared with not rinsing the mouth at all. This brings into question the magnitude of the effect of CHO mouth rinsing reported in previous studies that did not include a no-rinse condition.

Etiology of vocal fold paralysis is broad: e. g. iatrogenic/traumatic, associated with neoplasms or with systemic diseases. The cause of idiopathic paralysis is unknown. The main symptom of unilateral vocal fold paralysis is hoarseness because of a remaining glottic gap during phonation. Patients with bilateral vocal fold paralysis typically have no impairment of the voice but dyspnea. Examination of patients with an idopathic vocal fold paralysis is a CT of the vagal nerve and recurrent laryngeal nerve from skull base to neck and mediastinum. Serological tests are not obligatory. Differential diagnosis of vocal fold immobility is vocal fold paralysis/neurological causes and arthrogene causes such as arytenoid subluxation, interarytenoid adhesion and vocal fold fixation in laryngeal carcinomas. Voice therapy is a promising approach for patients with unilateral vocal fold paralysis, but not all patients benefit sufficiently. Temporary vocal fold augmentation by injection medialization results in satisfactory voice quality that is comparable with a thyroplasty. Patients with bilateral vocal fold immobility show typically dyspnea requiring immediate therapy such as temporary tracheotomy or reversible laterofixation of the paralyzed vocal chord. If the paralysis persists a definitive enlargement of the glottic airway by eg. arytenoidectomy needs to be performed.

Vocal cords paralysis is the second most frequent cause of laryngeal stridor in children. Symptoms of congenital vocal cords paralysis can occur shortly after birth or later. Vocal cords paralysis can be unilateral or bilateral. Symptoms of unilateral paralysis include hoarse weeping or stridor during a deep inhalation. In children unilateral vocal cords paralysis often retreats spontaneously or can be completely compensated. Children with bilateral vocal cords paralysis present mainly breathing disorders while phonation is normal. Symptoms are different, starting from complete occlusion of respiratory tracts and ending on small symptoms connected with the lack of effort tolerance. When symptoms are severe, patients from this group require a tracheotomy. The lack of restoration of normal function of vocal cords or lack of complete compensation and maintenance of symptoms are an indication for surgical treatment. The aim of this study is to present results of the treatment of bilateral vocal cords paralysis in children using the endoscopic method of laterofixation of vocal cords. In the Pediatric ENT Department between 1998 and 2009 sixty four children with dyspnoea and/or phonation disorders caused by vocal cords paralysis were treated. In ten cases laterofixation of vocal cords was performed, in most cases with good result. In this article the authors present the method of endoscopic laterofixation and achieved results. Endoscopic laterofixation of vocal cords in children is a safe and an easy method of surgical treatment of bilateral vocal cords paralysis. This method can be used as a first and often as a one stage treatment of vocal cords paralysis. In some cases this procedure is insufficient and has to be completed with other methods.

We elicited isolated sleep paralysis (ISP) from normal subjects by a nocturnal sleep interruption schedule. On four experimental nights, 16 subjects had their sleep interrupted for 60 minutes by forced awakening at the time when 40 minutes of nonrapid eye movement (NREM) sleep had elapsed from the termination of rapid eye movement (REM) sleep in the first or third sleep cycle. This schedule produced a sleep onset REM period (SOREMP) after the interruption at a high rate of 71.9%. We succeeded in eliciting six episodes of ISP in the sleep interruptions performed (9.4%). All episodes of ISP except one occurred from SOREMP, indicating a close correlation between ISP and SOREMP. We recorded verbal reports about ISP experiences and recorded the polysomnogram (PSG) during ISP. All of the subjects with ISP experienced inability to move and were simultaneously aware of lying in the laboratory. All but one reported auditory/visual hallucinations and unpleasant emotions. PSG recordings during ISP were characterized by a REM/W stage dissociated state, i.e. abundant alpha electroencephalographs and persistence of muscle atonia shown by the tonic electromyogram. Judging from the PSG recordings, ISP differs from other dissociated states such as lucid dreaming, nocturnal panic attacks and REM sleep behavior disorders. We compare some of the sleep variables between ISP and non-ISP nights. We also discuss the similarities and differences between ISP and sleep paralysis in narcolepsy.

The case study reports on the effect of pharmacological, complementary, and alternative medicine including YNSA, Applied Kinesiology, and respiratory exercises in a 9-year-old boy with facial paralysis. The boy suffered from borreliosis and one-sided facial paralysis that occurred 3.5 weeks after being bitten by a tick and persisted despite 4 weeks of medication with antibiotics. In the first treatment, muscle function as assessed by the coachman׳s test was normalized, and improvement in the facial paralysis was observed. Within 8 additional treatments over a period of 2 months, the boy showed complete recovery. The case shows a multimodal approach to facial paralysis integrating pharmacological treatment and CAM including YNSA, Applied Kinesiology, and breathing exercises. Copyright © 2016.

Isolated sleep paralysis (ISP) has received scant attention in clinical populations, and there has been little empirical consideration of the role of fear in ISP episodes. To facilitate research and clinical work in this area, the authors developed a reliable semistructured interview (the Fearful Isolated Sleep Paralysis Interview) to assess ISP and their proposed fearful ISP (FISP) episode criteria in 133 patients presenting for panic disorder treatment. Of these, 29.3% met lifetime ISP episode criteria, 20.3% met the authors’ lifetime FISP episode criteria, and 12.8% met their recurrent FISP criteria. Both ISP and FISP were associated with minority status and comorbidity. However, only FISP was significantly associated with posttraumatic stress disorder, body mass, anxiety sensitivity, and mood and anxiety disorder symptomatology. PMID:20715166

Objective To determine lifetime prevalence rates of sleep paralysis. Data Sources Keyword term searches using “sleep paralysis”, “isolated sleep paralysis”, or “parasomnia not otherwise specified” were conducted using MEDLINE (1950-present) and PsychINFO (1872-present). English and Spanish language abstracts were reviewed, as were reference lists of identified articles. Study Selection Thirty five studies that reported lifetime sleep paralysis rates and described both the assessment procedures and sample utilized were selected. Data Extraction Weighted percentages were calculated for each study and, when possible, for each reported subsample. Data Synthesis Aggregating across studies (total N = 36533), 7.6% of the general population, 28.3% of students, and 31.9% of psychiatric patients experienced at least one episode of sleep paralysis. Of the psychiatric patients with panic disorder, 34.6% reported lifetime sleep paralysis. Results also suggested that minorities experience lifetime sleep paralysis at higher rates than Caucasians. Conclusions Sleep paralysis is relatively common in the general population and more frequent in students and psychiatric patients. Given these prevalence rates, sleep paralysis should be assessed more regularly and uniformly in order to determine its impact on individual functioning and better articulate its relation to psychiatric and other medical conditions.

A 19-year-old girl presented at our emergency room with hypokalemic periodic paralysis. She had a thyrotoxic goiter and had experienced three paralytic attacks during the previous 2 years on occasions when she stopped taking antithyroid drugs. In addition to thyrotoxic periodic paralysis (TPP), she had metabolic acidosis, urinary potassium loss, polyuria and polydipsia. Her reduced ability to acidify urine during spontaneous metabolic acidosis was confirmed by detection of coexisting distal renal tubular acidosis (RTA). The polyuria and polydipsia were caused by nephrogenic diabetes insipidus, which was diagnosed using the water deprivation test and vasopressin administration. Her recurrent and frequent paralytic attacks may have been the combined effects of thyrotoxicosis and RTA. Although the paralytic attack did not recur after improving the thyroid function, mild acidosis and nephrogenic DI have been remained subsequently. Patients with TPP, especially females with atypical metabolic features, should be investigated for possible precipitating factors.

Isolated diaphragmatic paralysis due to obstetrical factors is rare and therapeutic management modalities are not quite clear. A neonate born by breech delivery presented with respiratory distress due to isolated paralysis of the right hemidiaphragm. The clinical course was progressive, his condition worsening with oxygen supplementation. Continuous positive airway pressure (CPAP) delivered via a nasal cannula was started in the one-month-old child, inducing gradual improvement towards recovery at the age of two months and a half. Non-invasive nasal CPAP should be proposed for the treatment of phrenic nerve obstetrical palsy before introducing more invasive ventilation techniques. Surgical plication should be delayed until the child reaches the age of at least three months.

Hyperkalemic periodic paralysis (HyperKPP) is a disease characterized by periods of myotonic discharges and paralytic attacks causing weakness, the latter associated with increases in plasma [K(+)]. The myotonic discharge is due to increased Na(+) influx through defective Na(+) channels that triggers generation of several action potentials. The subsequent increase in extracellular K(+) concentration causes excessive membrane depolarization that inactivates Na(+) channels triggering the paralysis. None of the available treatments is fully effective. This paper reviews the capacity of Na(+) K(+)ATPase pumps, KATP and ClC-1 Cl(-) channels in improving membrane excitability during muscle activity and how using these three membrane components we can study future and more effective treatments for HyperKPP patients. The review of current patents related to HyperKPP reinforces the need of novel approaches for the treatment of this channelopathy.

No procedure perfectly restores a face paralyzed by surgical ablation of the facial nerve. Although dynamic reconstructive procedures are preferred for treating patients with complete facial paralysis, various conditions contraindicate their use, making static suspension of the paralyzed face a reasonable surgical alternative. Expanded polytef soft-tissue patch (polytetrafluoroethylene; Gore-Tex Soft-Tissue Patch, Gore-Tex, W. L. Gore & Assoc Inc., Flagstaff, Ariz) was used to help correct midfacial and perioral asymmetries in 11 patients with complete unilateral facial paralysis. All patients had previous surgical ablation of the facial nerve and were not considered good candidates for dynamic facial reconstruction. Midfacial and perioral asymmetries were improved in all patients using this technique of static soft-tissue suspension. One postoperative infection and two cases of postoperative suture extrusion were observed in the patient population. Other complications associated with the use of Gore-Tex Soft-Tissue Patch for facial suspension were limited to technical factors.

Peripheral facial nerve paralysis (PFNP) after mandibular interventions has been reported in the literature. In most cases, paralysis begins immediately after the injection of the mandibular anesthesia, and duration of facial weakness is less than 12 hours. However, there are few documented cases of PFNP after maxillary dental or surgical procedures. A variety of mechanisms have been associated to PFNP, including viral reactivation, demyelination, edema, vasospasm, and trauma. The purpose of this presentation was to report a rare case of facial paralysis that occurred after an upper third molar extraction. The cause of the PFNP and the importance of the multidisciplinary approach in the management are emphasized.

We describe a 37-year-old man with a 4-month history of episodic muscular weakness, involving mainly lower-limbs. Hypokalemia was documented in one episode and managed with intravenous potassium chloride. Hyperthyroidism was diagnosed 4 months after onset of attacks because of mild symptoms. The patient was subsequently diagnosed as having thyrotoxic periodic paralysis associated with Graves’ disease. Treatment with propranolol and methimazol was initiated and one year later he remains euthyroid and symptom free. Thyrotoxic periodic paralysis is a rare disorder, especially among Caucasians, but it should always be considered in patients with acute paralysis and hypokalemia, and thyroid function should be evaluated.

Purpose To investigate the long-term relationships between dry mouth, fluid intake and overactive bladder symptoms in women undergoing treatment with fesoterodine. We hypothesize that women who experience dry mouth will increase their fluid intake and worsen their urinary symptoms. Materials and Methods We conducted a prospective ancillary study to a 9 month open-label trial of fesoterodine for women with urgency urinary incontinence. Fluid intake was measured and compared according to reported dry mouth. Multivariable analysis was used to study the interaction between dry mouth, fluid intake and urinary symptoms. Results During the study, women without dry mouth (n=407) significantly reduced their fluid intake (mean decrease of 172.1 mL, median decrease of 118.3 mL, p= 0.02), while women with dry mouth (n=91) did not (mean decrease of 95.8 mL, median decrease of 118.3 mL, p=0.54). On univariable analysis, a greater proportion of women who experienced dry mouth reported improvement in their urinary symptoms compared to women without dry mouth (60.5% versus 47.2%, p=0.03). On multivariable analysis, Black/ African American women were less likely to report dry mouth (OR 0.4 95%CI 0.2–0.9, p=0.03) and older women were less likely to report improvement in urinary symptoms (OR 0.98 95%CI 0.96–0.99, p= 0.003). Factors not associated with improvement in urinary symptoms on multiple regression were dry mouth, baseline fluid intake volume, change in fluid intake volume, and caffeine intake volume. Conclusions In women with overactive bladder receiving fesoterodine, dry mouth may prevent women from restricting fluid intake, but does not diminish treatment efficacy. PMID:26682757

Considerable evidence now demonstrates that extensive functional and anatomical reorganization following spinal cord injury occurs in centers of the brain that have some input into spinal motor pools. This is very encouraging, given the accumulating evidence that new connections formed across spinal lesions may not be initially functionally useful. The second area of advancement in the field of paralysis recovery is in the development of effective interventions to counter axonal growth inhibition. A third area of significant progress is the development of robotic devices to quantify the performance level of motor tasks following spinal cord injury and to 'teach' the spinal cord to step and stand. Advances are being made with robotic devices for mice, rats and humans.

The goal of World Health Organization is to reach the global eradication of poliomyelitis during the first decade of the third millennium. To achieve the certification of the eradication of the disease the main strategy is the Acute Flaccid Paralysis (AFP) surveillance. In Italy the active AFP surveillance was performed at national level since 1997. In the Latium region the active surveillance was performed since January 1997 by the laboratory of virology of Institute of Hygiene G Sanarelli which established a regional hospital network. During the years of survey 7 cases were found in 1997 (0.87/100,000), 4 in 1998 (0.5/100,000), 2 in 1999 (0.25/100,000) and 2 in 2000. No wild polioviruses were detected.

Although traumatic injury of the facial nerve is a relatively common condition in neurosurgical practice, bilateral lesions related to fracture of temporal bones are seldom seen. We report the case of a 38-year-old patient admitted to Intensive Care Unit after severe head trauma requiring ventilatory support (Glasgow Coma Scale of 7 on admission). A computed tomography (CT) scan confirmed a longitudinal fracture of the right temporal bone and a transversal fracture of the left. After successful weaning from respirator, bilateral facial paralysis was observed. The possible aetiologies for facial diplegia differ from those of unilateral injury. Due to the lack of facial asymmetry, it can be easily missed in critically ill patients, and both the high resolution CT scan and electromyographic studies can be helpful for correct diagnosis.

Relatively little is known about isolated sleep paralysis (ISP), and no empirically supported treatments are available. This study aims to determine: the clinical impact of ISP, the techniques used to prevent or disrupt ISP, and the effectiveness of these techniques. 156 undergraduates were assessed with lifetime ISP using a clinical interview. 75.64% experienced fear during ISP, and 15.38% experienced clinically significant distress/interference, while 19.23% attempted to prevent ISP, and 79.31% of these believed their methods were successful. Regarding disruption, 69.29% made attempts, but only 54.12% reported them effective. Disruption was more common than prevention, but several techniques were useful. Encouraging individuals to utilize these techniques and better monitor their symptoms may be an effective way to manage problematic ISP.

Since January 1992, we adopted a new method of myocardial protection: warm blood cardioplegia with continuous ante-retrograde combined delivery during normothermic cardiopulmonary bypass, (CPB) instead of cold blood intermittent cardioplegia plus topical ice slush in hypothermic CPB. We have compared postoperative chest X-rays of 50 patients who underwent elective coronary artery bypass with normothermic CPB to postoperative chest X-rays, of 50 patients operated upon with hypothermia. In the cold group transitory diaphragmatic paralysis, as well as pleural effusions and thoracentesis related to the hypothermia, and topical cooling, were statistically increased over that of warm group. The data suggest that topical cooling with slush ice is responsible for phrenic nerve injury and that warm heart surgery has no associated incidence of diaphragmatic injury.

1. The effects of procaine on neuromuscular transmission in the rat phrenic nerve diaphragm preparation have been examined using intracellular recording techniques. 2. The paralysis produced by procaine resembled that produced by tubocurarine and it is concluded that this effect of procaine results from a change in post-junctional sensitivity to transmitter; at low rates of stimulation procaine did not depress the transmitter release. 3. During high frequency stimulation of the phrenic nerve a distinct form of prejunctional failure was observed. It is suggested that this depression results from a combination of local anaesthesia and anoxia and that it would explain reports of a reduction in the amount of transmitter released when assayed in a conventional manner.

HYPP is characterized by sporadic attacks of muscle tremors, weakness and/or collapse, lasting for variable periods of time. Diagnosis is based on physical findings in association with hyperkalemia. In horses with HYPP, the regulation of ion transport through the sodium channels in the muscle cells occasionally fails, causing uncontrollable muscle twitching. Further investigations into molecular genetics reveals a mutation in the gene responsible for sodium and potassium regulation. The identification of this gene mutation is the basis for the blood test used to diagnose HYPP. HYPP is inherited as an autosomal dominant trait. Treatment of HYPP attacks by intravenous application of calcium gluconate, bicarbonate and glucose results in rapid recovery. Consequent dietary management and daily administration of acetazolamide effectively controls the disease.

Poliomyelitis is a viral, nervous system disease that affects both the upper and the lower extremities. The treatment of severe coxarthrosis in these patients with total hip arthroplasty (THA) has been widely questioned because of the high risk of subsequent complications. The aim of the present study was to describe both radiological and medium term clinical results in a series of patients with post polio residual paralysis that underwent THA. We report a retrospective review of a series of 5 five patients diagnosed with severe coxarthrosis secondary to post polio residual paralysis who were operated between 2008 and 2012. Uncemented THA was performed in all cases by the same surgeon. Clinical evaluation was carried out using the Harris Hip Score (HHS) at the preoperative visit, at 6 months, and annually after surgery. The median age was 47 years, and the median followup was 55 months (interquartile range P25-P75: range 31-72 months). According to the HHS, a significant clinical improvement was observed in all patients with a median score of 81 points (interquartile range P25-P75: range 74-89) at 1 year of followup. A case of relapsing dislocation that required revision surgery of the implant was recorded. No cases of component loosening were found. THA surgery in patients with post polio residual paralysis is a complex procedure with a significant complication rate, but a predictable clinical improvement may encourage surgeons to perform in patients with severe coxarthrosis and moderate functional expectations.

The means by which muscle function modulates bone homeostasis is poorly understood. To begin to address this issue, we have developed a novel murine model of unilateral transient hindlimb muscle paralysis using botulinum toxin A (Botox). Female C57BL/6 mice (16 weeks) received IM injections of either saline or Botox (n = 10 each) in both the quadriceps and calf muscles of the right hindleg. Gait dysfunction was assessed by multi-observer inventory, muscle alterations were determined by wet mass, and bone alterations were assessed by micro-CT imaging at the distal femur, proximal tibia, and tibia mid-diaphysis. Profound degradation of both muscle and bone was observed within 21 days despite significant restoration of weight bearing function by 14 days. The muscle mass of the injected quadriceps and calf muscles was diminished −47.3% and −59.7%, respectively, vs. saline mice (both P < 0.001). The ratio of bone volume to tissue volume (BV/TV) within the distal femoral epiphysis and proximal tibial metaphysis of Botox injected limbs was reduced −43.2% and −54.3%, respectively, while tibia cortical bone volume was reduced −14.6% (all P < 0.001). Comparison of the contralateral non-injected limbs indicated the presence of moderate systemic effects in the model that were most probably associated with diminished activity following muscle paralysis. Taken as a whole, the micro-CT data implied that trabecular and cortical bone loss was primarily achieved by bone resorption. These data confirm the decisive role of neuromuscular function in mediating bone homeostasis and establish a model with unique potential to explore the mechanisms underlying this relation. Given the rapidly expanding use of neuromuscular inhibitors for indications such as pain reduction, these data also raise the critical need to monitor bone loss in these patients. PMID:16185943

1. Fowl paralysis (neurolymphomatosis gallinarum) is a disease entity, with characteristic clinical and pathological features. 2. The disease occurs in all parts of the United States, Holland, Austria and probably South America. 3. The disease appears to be endemic in certain foci. Having once appeared, the disease tends to persist through successive years. 4. It occurs with about equal frequency in both sexes; all common breeds may be affected. 5. Symptoms appear between the 3rd and 18th months. Typical clinical cases have not been observed outside of these limits. 6. The conspicuous symptoms are (a) asymmetrical, partial and progressive paralysis of the wings and both legs, and rarely of neck muscles; (b) occasional grey discoloration of iris, with blindness. Nutrition is usually preserved. 7. The duration is variable; the outcome is usually fatal, but spontaneous recovery may rarely occur. 8. The principal pathological changes are found in the nervous system. In the peripheral nerves, the essential feature is an intense infiltration of lymphoid, plasma cells, and large mononuclears. This is accompanied by a myelin degeneration in the more advanced lesions, but the cellular infiltrations appear to precede the degenerative changes. In brain, cord and meninges, there are similar infiltrations predominantly perivascular. Infiltrations of the iris with lymphoid and plasma cells are found in the cases showing gross discoloration of the iris. Visceral lymphomata, originating usually in the ovary, are associated in a certain percentage of the cases. Evidence is presented in favor of the view that this association is not accidental, and that the lymphomata are a manifestation of the disease. 9. Infiltrations of the spinal cord and brain, rarely of the peripheral nerves, are frequently present in birds showing no clinical symptoms. These are interpreted as mild cases of the same disease. 10. No microorganisms of etiological significance have been demonstrated in the

A 67-year-old woman suffered from a burning mouth feeling for 1.5 years and was referred by her dentist to a saliva clinic. At the clinic persistent xerostomia was diagnosed, and Sjögren's syndrome was suspected. After 1 year, a new measurement of the saliva secretion was carried out, which revealed a further decline in saliva secretion rate. The patient was consequently treated with an intra-oral electrostimulating device in order to stimulate the saliva secretion rate and reduce the feeling of a dry mouth. After 2 weeks, the patient experienced a considerable improvement of the subjective oral dryness.

To elucidate a potential role for insulin-mediated extra-renal potassium disposal in the clinical syndrome of hypokalemic periodic paralysis, an obese affected man was studied using the euglycemic insulin clamp, which, in normal and obese subjects, produces predictable, insulin dose-dependent declines in plasma potassium levels. During a 20 mU/m2/minute euglycemic clamp (insulin level, 88 microU/ml) procedure, while the patient with hypokalemic periodic paralysis demonstrated severe resistance to insulin-mediated glucose uptake (glucose uptake 50 percent of that of normal control subjects, n = 17), his plasma potassium declined to a degree similar to that seen in normal subjects. During a subsequent higher dose, 200 mU/m2/minute insulin infusion (insulin level, 914 microU/ml), plasma potassium declined to 2.5 meq/liter, a value significantly below that seen in normal (n = 19) (3.3 +/- 0.1 meq/liter) and obese (n = 6) (3.2 +/- 0.1 meq/liter) subjects. During this study, paralysis began in the patient's hand and forearm at the potassium nadir and lasted three hours, despite restoration of normokalemia 30 minutes after paralysis began. Glucose disposal rates during this high-dose insulin infusion were one-half that seen in lean control subjects (n = 19) and similar to those in obese control subjects. If these findings are representative of hypokalemic periodic paralysis and can be generalized to larger numbers of patients, they indicate several new features of this syndrome. The ability of insulin to induce hypokalemia is enhanced in this syndrome even in the presence of marked coexistent obesity-related resistance to the action of insulin to promote glucose utilization. Enhanced sensitivity of potassium uptake systems to activation by insulin (and other factors) may be a central feature of this syndrome. Additionally, paralytic hypokalemia can be induced during a euglycemic insulin clamp procedure, which could be utilized as a diagnostic test for this syndrome.

Patients with unilateral vocal fold paralysis may demonstrate different degrees of voice perturbation depending on the position of the paralyzed vocal fold. Understanding the effectiveness of voice therapy in this population may be an important coefficient to define the therapeutic approach. To evaluate the voice therapy effectiveness in the short, medium and long-term in patients with unilateral vocal fold paralysis and determine the risk factors for voice rehabilitation failure. Prospective study with 61 patients affected by unilateral vocal fold paralysis enrolled. Each subject had voice therapy with an experienced speech pathologist twice a week. A multidimensional assessment protocol was used pre-treatment and in three different times after voice treatment initiation: short-term (1-3 months), medium-term (4-6 months) and long-term (12 months); it included videoendoscopy, maximum phonation time, GRBASI scale, acoustic voice analysis and the portuguese version of the voice handicap index. Multiple comparisons for GRBASI scale and VHI revealed statistically significant differences, except between medium and long term (p<0.005). The data suggest that there is vocal improvement over time with stabilization results after 6 months (medium term). From the 28 patients with permanent unilateral vocal fold paralysis, 18 (69.2%) reached complete glottal closure following vocal therapy (p=0.001). The logistic regression method indicated that the Jitter entered the final model as a risk factor for partial improvement. For every unit of increased jitter, there was an increase of 0.1% (1.001) of the chance for partial improvement, which means an increase on no full improvement chance during rehabilitation. Vocal rehabilitation improves perceptual and acoustic voice parameters and voice handicap index, besides favor glottal closure in patients with unilateral vocal fold paralysis. The results were also permanent during the period of 1 year. The Jitter value, when elevated, is

Limitation of mouth opening is a common source of referral to an orofacial pain clinic with a proposed diagnosis of Temporomandibular Joint Dysfunction (TMD). The word "trismus" is defined by the American academy of orofacial pain as: "Myospasm of masticatory muscles specifically causing limited jaw opening; early symptom of tetanus". Therefore, once trismus is suspected, TMD should be ruled out. However, it is not uncommon to find the usage of this term to describe severe limitation of opening by causes other than myospasm, therefore posing the risk of misdiagnosis. The purpose of this article is to describe the differential diagnosis of hard end limitation of opening with emphasis on the clinical tools used to differentiate between muscle source of hard end limitation and other sources of hard end limitation. Several cases of hard end limitation of mouth opening are presented and through them major principles of orofacial diagnosis are discussed.

Burning mouth syndrome (BMS) is mainly found in middle aged or elderly women and is characterized by intense burning or itching sensation of the tongue or other regions of the oral mucosa. It can be accompanied by xerostomia and dysgeusia. The syndrome generally manifests spontaneously, and the discomfort is typically of a continuous nature but increases in intensity during the evening and at night. Although BMS classically has been attributed to a range of factors, in recent years evidence has been obtained relating it peripheral (sensory C and/or trigeminal nerve fibers) or central neuropathic disturbances (involving the nigrostriatal dopaminergic system). The differential diagnosis requires the exclusion of oral mucosal lesions or blood test alterations that can produce burning mouth sensation. Patient management is based on the avoidance of causes of oral irritation and the provision of psychological support. Drug treatment for burning sensation in primary BMS of peripheral origin can consist of topical clonazepam, while central type BMS appears to improve with the use of antidepressants such as duloxetine, antiseizure drugs such as gabapentin, or amisulpride.

Background Burning mouth syndrome (BMS) is a frequently occurring disease characterized by a burning or painful sensation in the tongue and/or other oral sites without clinical mucosal abnormalities or lesions. Its etiopathology is unknown, although local, systemic, and psychological factors have been associated with BMS. The syndrome is multifactorial, and its management remains unsatisfactory. The purpose of this study was to obtain preliminary data regarding the efficacy and tolerability of amisulpride in BMS treatment. Methods The subjects were treated with amisulpride (50 mg/day) for 24 weeks. Efficacy assessment included a visual analogue scale (VAS) for pain intensity, the Hamilton Rating Scale for Depression (HAM-D), the Hamilton Rating Scale for Anxiety (HASM-A), and the Clinical Global Impression Scale-Efficacy Index (CGI-EI). Results The treatment regimens resulted in a significant improvement in burning mouth symptoms from baseline at week 24, as indicated by the quantitative mean illness duration VAS score, HAM-D, and HAM-A. Amisulpride appears to be effective and patients show a rapid response to treatment. No serious adverse effects were encountered in these patients. Conclusions Amisulpride is effective and well tolerated as a short-term treatment. It is particularly efficacious at the start of treatment and has shorter response latency. Double-blind placebo-controlled trials are needed for further assessment of the efficacy of amisulpride in BMS treatment. PMID:22719802

Evaluation of Physiologic Frequency Range (PFR) and Musical Frequency Range (MRP) of Phonation was performed on 56 adults (singers and nonsingers) presenting with superior laryngeal nerve (SLN) paresis or paralysis confirmed by laryngeal electromyography. The most common etiology was neuritis (69.7%), followed by iatrogenic and unknown causes,each accounting for 10.2% of cases, and finally trauma (8.9%). Both female and male singers with SLN paresis or paralysis had significantly higher PFR and MPR than nonsingers. Female classical singers presented PFR and MPR of up to 10 semitones (ST) higher than nonclassical singers and nonsingers. The lowest PFR and musical ranges were found in patients with SLN paresis associated with recurrent laryngeal nerve paresis or paralysis. The authors suggest that voice range measurement is a useful parameter for analyzing the effects of SLN paresis or paralysis on voice and that it may also assist in measuring outcome following voice therapy.

Laryngeal paralysis is the effect of an inability to abduct the arytenoid cartilages during inspiration, resulting in respiratory signs consistent with partial airway obstruction. The aetiology of the disease can be congenital (hereditary laryngeal paralysis or congenital polyneuropathy), or acquired (trauma, neoplasia, polyneuropathy, endocrinopathy). The most common form of acquired laryngeal paralysis (LP) is typically seen in old, large breed dogs and is a clinical manifestation of a generalised peripheral polyneuropathy recently referred to as geriatric onset laryngeal paralysis polyneuropathy. Diagnosing LP based on clinical signs, breed and history has a very high sensitivity (90%) and can be confirmed bylaryngeal inspection. Prognosis after surgical correction depends on the aetiology: traumatic cases have a good prognosis, whereas tumour-induced or polyneuropathy-induced LP has a guarded prognosis. Acquired idiopathic LP is a slow progressive disease, with dogs reaching median survival times of 3-5 years after surgical correction.

We explore the existence and underlying neural mechanism of a new norm endorsed by both black and white Americans for managing interracial interactions: "racial paralysis', the tendency to opt out of decisions involving members of different races. We show that people are more willing to make choices--such as who is more intelligent, or who is more polite-between two white individuals (same-race decisions) than between a white and a black individual (cross-race decisions), a tendency which was evident more when judgments involved traits related to black stereotypes. We use functional magnetic resonance imaging to examine the mechanisms underlying racial paralysis, to examine the mechanisms underlying racial paralysis, revealing greater recruitment of brain regions implicated in socially appropriate behavior (ventromedial prefrontal cortex), conflict detection (anterior cingulate cortex), deliberative processing (dorsolateral prefrontal cortex), and inhibition (ventrolateral prefrontal cortex). We also discuss the impact of racial paralysis on the quality of interracial relations.

Hypokalemic periodic paralysis is a rare disorder characterized by episodic attacks of muscle flaccidity associated with low serum potassium levels. We report twelve patients with normokalemic and hypokalemic periodic paralysis due to various mutations who developed hypokalemic paralytic episodes following a single dose or short-term administration of glucocorticoids. We hypothesize that glucocorticoids cause hypokalemia due to their stimulation of the Na(+)-K(+) ATPase mediated by insulin and amylin and due to their side effect of insulin resistance resulting in hyperglycemia. This report adds to the clinical description of glucocorticoids as a trigger of attacks of hypokalemic periodic paralysis indicating that glucocorticoids should be administered with caution in patients with periodic paralysis.

Whereas cases of unilateral obstetric brachial plexus paralysis have been sufficiently described and discussed in the literature cases of bilateral obstetric brachial plexus paralysis are extremely rare and so far have not been mentioned and discussed satisfactorily. We present a case of bilateral obstetric brachial plexus paralysis in an 8-months-old white boy. We performed a neurotisation of the Nervus suprascapularis with the Nervus accessorius and an Oberlin procedure on both sides in two operative steps. In an early follow-up 6 months after the second operation and intensive physiotherapy the little patient was able to crawl with the active help of both arms. Bilateral obstetric brachial plexus paralysis is a very rare incidence in infants. An interdisciplinary approach including paediatrics, plastic surgeons, neurosurgeons, neurologists, radiologists and physiotherapists is essential for the success of treatment strategies in such cases.

Thyrotoxic periodic paralysis (TPP) is a rare metabolic disorder characterised by muscular weakness and paralysis in predisposed thyrotoxic patients. Although patients with TPP are almost uniformly men of Asian descent, cases have been reported in Caucasian and other ethnic populations. The rapid increase in ethnic diversity in Western and European nations has led to increase in TPP reports, where it was once considered exceedingly rare. Correcting the hypokalaemic and hyperthyroid state tends to reverse the paralysis. However, failure to recognise the condition may lead to delay in diagnosis and serious consequences including respiratory failure and death. We describe a young man who was diagnosed with hyperthyroidism who presented with acute paralysis. The clinical characteristics, pathophysiology and management of TTP are reviewed. PMID:22927268

Rhabdomyolysis continues to appear with increasing frequency and represents a medical emergency requiring rapid appropriate treatment. One of the unusual causes of nontraumatic rhabdomyolysis is hypokalemic periodic paralysis without secondary causes. Primary hypokalemic periodic paralysis is a rare genetic disease characterized by episodic attacks of muscle weakness due to decreases in serum potassium. A 30-year-old woman who had 3 episodic attacks of hypokalemic periodic paralysis was admitted in emergency room with sudden onset symmetrical muscle weakness. After several hours, she started to complain myalgia and severe ache in both calves without any changes. Laboratory test showed markedly elevated creatine phosphokinase, lactic dehydrogenase levels with hypokalemia, rhabdomyolysis resulting from hypokalemia was diagnosed. Here, we report an unusual case of rhabdomyolysis caused by severe hypokalemia, which was suggested a result of familial hypokalemic periodic paralysis. PMID:28255549
A flaccid paralysis results from damage to any part of the lower motor neurone, from destruction of the anterior horn cell by poliomyelitis to injury of the peripheral axon by trauma or disease. Reconstructive surgery can do much to alleviate the residual paralysis. The indications and timing for surgery are considered. Certain well-tried operative techniques are described, from tendon transplantation to arthrodeses of joints, and the relative merits of each procedure are evaluated and placed in perspective.

Facial paralysis in newborns can leave functional sequelae. Determining the evolution and amount of functional losses requires consistent evaluation methods that measure, quantitatively, the evolution of clinical functionality. This paper reports an innovative method of facial assessment for the case of a child 28 days of age with unilateral facial paralysis. The child had difficulty breast feeding, and quickly responded to the physical therapy treatment.

The pharynx is anatomically complex and evaluation can be difficult even with cross-sectional imaging. Eight animals had computed tomography (CT) studies of the head performed with the mouth open and closed. The studies were anonymized and evaluated by four radiologists for visibility of six anatomic regions (dorsal wall of nasopharynx, lumen of nasopharynx, dorsal margin of the soft palate, ventral margin of the soft palate, oropharynx, and laryngopharynx) and for certainty of a normal or abnormal diagnosis of four different anatomic regions (nasopharynx, soft palate, oropharynx, and laryngopharynx). Mean visual scores differed significantly between mouth positions and were improved when the mouth was open. The ability of radiologists to classify anatomic regions as normal or abnormal vs. unsure also varied between mouth positions, and there was greater uncertainty when the mouth was closed. In addition, estimated volume of the air-filled nasopharynx differed significantly as a function of mouth position and was greater when the mouth was open (mean=1.187 cm(3) , SE=0.177) vs. closed (mean=0.584 cm(3) , SE=0.116). Computed tomographic evaluation of the pharynx can be improved with the mouth open. © 2011 Veterinary Radiology & Ultrasound.

True vocal fold (TVF) paralysis is a common cause of neonatal stridor and airway obstruction, though bilateral TVF paralysis is seen less frequently. Rare cases of familial congenital TVF paralysis have been described with implied genetic origin, but few genetic abnormalities have been discovered to date. The purpose of this study is to describe a novel chromosomal translocation responsible for congenital bilateral TVF immobility. The charts of three patients were retrospectively reviewed: a 35 year-old woman and her two children. The mother had bilateral TVF paralysis at birth requiring tracheotomy. Her oldest child had a similar presentation at birth and also required tracheotomy, while the younger child had laryngomalacia without TVF paralysis. Standard karyotype analysis was done using samples from all three patients and the parents of the mother, to assess whether a chromosomal abnormality was responsible. Karyotype analysis revealed the same balanced translocation between chromosomes 5 and 14, t(5;14) (p15.3, q11.2) in the mother and her two daughters. No other genetic abnormalities were identified. Neither maternal grandparent had the translocation, which appeared to be a spontaneous mutation in the mother with autosomal dominant inheritance and variable penetrance. A novel chromosomal translocation was identified that appears to be responsible for familial congenital bilateral TVF paralysis. While there are other reports of genetic abnormalities responsible for this condition, we believe this is the first describing this particular translocation. Copyright © 2014 Elsevier Ireland Ltd.

Accurate surveillance for polio is essential for eradication. Surveillance systems for polio has been developed under the guidance of the global polio eradication initiative. Surveillance of cases of acute flaccid paralysis among children less than 15 years of age is a key component for a well functioning polio surveillance system. The surveillance system works through a network of surveillance medical officers, the responsibility of them lies in assisting the health services departments of all states and maintaining a network of acute flaccid paralysis reporting sites and rapidly investigating the cases. Surveillance activities begin when a child comes in contact with a healthcare provider who in turn informs the officer in charge of acute flaccid paralysis surveillance. The goal of the polio network laboratories is to provide accurate and timely results of wild poliovirus detection in stool samples of cases of acute flaccid paralysis. Strong linkages have been established between the acute flaccid paralysis surveillance system and the laboratory network. Laboratories complete poliovirus isolation and if poliovirus is isolated, these are submitted for intratypic differentiations. Acute flaccid paralysis surveillance in India has demonstrated that the eradication activities implemented in India led to dramatic reduction and restriction in the number of cases and geographic spread of poliovirus transmission.

Sleep paralysis is a relatively common but under-researched phenomenon. While the causes are unknown, a number of studies have investigated potential risk factors. In this article, we conducted a systematic review on the available literature regarding variables associated with both the frequency and intensity of sleep paralysis episodes. A total of 42 studies met the inclusion criteria. For each study, sample size, study site, sex and age of participants, sleep paralysis measure, and results of analyses looking at the relationship(s) between sleep paralysis and associated variable(s) were extracted. A large number of variables were associated with sleep paralysis and a number of themes emerged. These were: substance use, stress and trauma, genetic influences, physical illness, personality, intelligence, anomalous beliefs, sleep problems and disorders (both in terms of subjective sleep quality and objective sleep disruption), symptoms of psychiatric illness in non-clinical samples (particularly anxiety symptoms), and psychiatric disorders. Sleep paralysis appears to be particularly prevalent in post-traumatic stress disorder, and to a less degree, panic disorder. Limitations of the current literature, directions for future research, and implications for clinical practice are discussed. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Sleep paralysis accompanied by hypnopompic ('upon awakening') hallucinations is an often-frightening manifestation of discordance between the cognitive/perceptual and motor aspects of rapid eye movement (REM) sleep. Awakening sleepers become aware of an inability to move, and sometimes experience intrusion of dream mentation into waking consciousness (e.g. seeing intruders in the bedroom). In this article, we summarize two studies. In the first study, we assessed 10 individuals who reported abduction by space aliens and whose claims were linked to apparent episodes of sleep paralysis during which hypnopompic hallucinations were interpreted as alien beings. In the second study, adults reporting repressed, recovered, or continuous memories of childhood sexual abuse more often reported sleep paralysis than did a control group. Among the 31 reporting sleep paralysis, only one person linked it to abuse memories. This person was among the six recovered memory participants who reported sleep paralysis (i.e. 17% rate of interpreting it as abuse-related). People rely on personally plausible cultural narratives to interpret these otherwise baffling sleep paralysis episodes.

Death of motor neurones following invasion of the central nervous system by poliovirus may result in paralysis of specific muscles. Virulence may be tested by injection into monkeys by routes which bypass natural infection. Transmissibility is also very important, but cannot be measured, only inferred. An infection may lead to immunity or paralysis. In epidemics, the highest incidence among children 0-2 years was 2% and among those over 10 years was 25%: these figures fit a model of genetic susceptibility of homozygotes and heterozygotes with phenotypic susceptibility increasing with age. Hypogamma-globulinemics, some neonates and pregnant women are more susceptible than others. Intra-muscular injections may increase the risk of paralysis. Strenuous exercise and IM injections given when poliovirus has already reached the spinal cord can increase the severity of paralysis or convert a non-paralytic attack to paralysis. Although vaccines reduced polio in temperate countries, polio was thought to be no problem in the tropics. Since 1977 polio has been recognised as a massive problem in the third world: because it affects babies and very young children, it is properly infantile paralysis.

Rifampin is one of the most important drugs in first-line therapies for tuberculosis. The renal toxicity of rifampin has been reported sporadically and acute tubulointerstitial nephritis (ATIN) is a frequent histological finding. We describe for the first time a case of ATIN and Fanconi syndrome presenting as hypokalemic paralysis, associated with the use of rifampin. A 42-year-old man was admitted with sudden-onset lower extremity paralysis and mild renal insufficiency. He had been treated for pulmonary tuberculosis with isoniazid, rifampin, and ethambutol for 2 months. Laboratory tests revealed proteinuria, profound hypokalemia, hyperchloremic metabolic acidosis with a normal anion gap, positive urine anion gap, hypophosphatemia with hyperphosphaturia, hypouricemia with hyperuricosuria, glycosuria with normal serum glucose level, generalized aminoaciduria, and β2-microglobulinuria. A kidney biopsy revealed findings typical of ATIN and focal granular deposits of immunoglubulin A and complement 3 in the glomeruli and tubules. Electron microscopy showed epithelial foot process effacement and electron-dense deposits in the subendothelial and mesangial spaces. Cessation of rifampin resolved the patient's clinical presentation of Fanconi syndrome, and improved his renal function and proteinuria. This case demonstrates that rifampin therapy can be associated with Fanconi syndrome presenting as hypokalemic paralysis, which is a manifestation of ATIN. Kidney function and the markers of proximal tubular injury should be carefully monitored in patients receiving rifampin.

By using the evidence-based medicine approach to analyze the optimum timing in acupuncture treatment for facial paralysis, to provide the scientific evidence for acupuncture clinical practices. Computer searches were conducted in the CNKI literature database from January 1994 to August 2009, using the keywords "facial paralysis", "acupuncture" and "acupuncture timing/treatment timing". According to the standard of Cochrane, the literatures were retrieved and conducted with evidence-based analysis. The SPSS 13.0 Software was used for the statistical analysis. Among the 133 retrieved literatures which met the inclusion criteria of the study, there were 11 literatures on the effect of acupuncture or electroacupuncture treatment in acute phase observation group and conventional medical treatment group. Using Mann-Whitney U test, the difference of treatment effect is statistically significant (P < 0.001). Early intervention in acupuncture treatment for facial paralysis in acute phase can improve the efficacy and promote neurological recovery. In the acute phase, animal experiments and clinical observations provide evidence to support the application of electric needle and traditional acupuncture treatments.

We present the surgical techniques and results of cross-facial nerve grafting that have been developed in the repair of ocular-oral synkinesis after facial paralysis. Eleven patients with ocular-oral synkinesis after facial paralysis underwent the cross-facial nerve grafting with facial nerve transposition at a tertiary academic hospital between 2003 and 2009. The patient selection for the study was based on the degree of disfigurement and facial function parameter rating using the Toronto Facial Grading System. The procedures used were surgeries done in two stages. All cases were followed up for 2 months to 6 years after the second surgery. The degree of improvement was evaluated at 6 to 7 months after the procedures. Six of the patients were followed up for more than 2 years after the stage-two surgery and demonstrated significant reduction in the ocular-oral synkinetic movements. The Toronto Facial Grading System scores from the postoperative follow-ups increased an average of 16 points (28%), and the patients had achieved symmetrical facial movement. We concluded that cross-facial nerve grafting with facial nerve branch transposition is effective and can be considered as an option for the repair of ocular-oral synkinesis after facial paralysis in select patients.

Facial paralysis is a incapacitating pathology that we treat with lengthening temporalis myoplasty for reanimation of the smile. To treat lagophthalmia, we use the extension of the levator of the upper eyelid according Tessier and the asymmetric external blepharorraphy. These techniques can optionally be combined with other techniques, as needed. However, many patients are embarrassed by the appearance of the lashes of the upper eyelid homolateral side facial paralysis. The cilia are lowered and horizontalised, creating a functional disorder by partial "amputation" of the visual field and aesthetic inconvenience. We describe a surgical technique to correct the malposition of the lashes. This technique can be carried out independently or in the lengthening of the temporal myoplasty or another surgical procedure on the eye. In case of extension of the levator of the upper eyelid, the technique we propose requires no additional incision. This is a simple technique and increases very little surgical time. It is fast, little or no morbid, reproducible and provides a significant improvement in the aesthetic and functional patient. This simple technique allows to provide both aesthetic and functional refinement for patients with facial paralysis sequelae. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

To explore the better therapeutic method for acute peripheral facial paralysis. One hundred and ninety-seven cases of acute peripheral facial paralysis were randomly divided into an observation group (n=125) and a control group (n=72). The observation group was treated by injection at acupoint combined with warming needle therapy at Yifeng (TE 17), Wangu (GB 12), Xiaguan (ST 7), Qianzheng (EX), and Taiyang (EX-HN 5). The control group was treated with electroacupuncture at Yifeng (TE 17), Yangbai (GB 14), Xiaguan (ST 7), etc. Their therapeutic effects were compared between the two groups. After three therapeutic courses, the cured rate and the total effective rate in the observation group were 76.0%, 100.0%, and 48.6%, 86.1% in the control group, respectively, with significant defferences between the two groups (all P < 0.01). Injection at acupoint combined with warming needle therapy could shorten the therapeutic cycle, improve the effectiveness, and decrease sequela in acute peripheral facial paralysis.

Referring to traditional therapeutical concepts of vocal fold paralysis a microphone-controlled computer programme was used for voice treatment in 13 patients with unilateral vocal fold paralysis. 6 of these patients were female, 7 were male. The age ranged from 18 to 72 years (mean: 50 years). The etiology of the paralysis was distributed as follows: post strumectomy (4 cases), post operation of the aortic arch (3 cases), post mediastinoscopy (1 case), post operation of the cervical vertebrae (1 case). 2 cases are not decided yet, 2 are probably idiopathic. The vocal fold dysfunction lasted between 24 hours and 8 years before our first examination, less than 4 weeks in 11 cases. With 1 exception (intermediate) the vocal fold position was classified as paramedian. 8 patients suffered from left, and 5 patients from right vocal fold paralysis. The voice treatment took place with a microphone-controlled speech viewer including an audio capture and playback adapter. 7 of the 15 training modules of the computer programme were chosen to be useful for voice training. Those modules can be differentiated in physical-technical modules showing voice spectra or pitch scales and in object-related modules showing images such as landscapes, animals and others. These programme-specific modules (monitor exercises) were primarily built to train the following voice qualities separately: loudness, pitch, voicing, voice onset, fundamental frequency, sustained phonation etc. Modifying certain therapeutic instructions (see Tables 1 and 2) the monitor exercises were used to improve the coordination of different voice parameters, thus resembling physiological speech.(ABSTRACT TRUNCATED AT 250 WORDS)

Scapular position and size deficiency is evident in obstetric brachial plexus paralysis (OBPP) patients due to the absence of balanced muscular forces acting on the scapula. Scapula stabilization (SS) procedures aim to restore a balanced musculature and anatomic position and to augment shoulder function and enhance developmental potential. Retrospective chart review of 106 patients with OBPP between March 1979 and March 2007 was performed. Forty-one female and 27 male were included in the study. In 38 patients, the paralysis was global, 13 had Erb's paralysis with C7 root involvement; in 18 patients, the lesion was limited to C5 and C6. X-rays were evaluated, and scapula dimensions were manually measured at several stages. Shoulder abduction (SA) and external rotation (SER) outcomes were also recorded. Mean improvement was 85.68° in shoulder abduction and 36.74° in shoulder external rotation. SA and SER improvement was significantly better in those who underwent SS procedures compared to those who did not (mean improvement was increased by 9.15° and 8.54°, respectively). Improvement was noted in all scapular dimensions, in all groups, postoperatively. However, the mean improvement in scapular height, big width, small width, and oblique axis discrepancies was 4.92, 14.04, 12.66, and 13.89 %, respectively, higher in patients who underwent SS procedures compared to those who did not. Dimensional discrepancies and functional outcomes are improved by SS procedures. Maximal results are attained in patients who have undergone both primary and secondary shoulder reconstruction before age 2.

The objective of this prospective naturalistic field study was to determine the distribution of naturally occurring sleep-paralysis (SP) episodes over the course of nocturnal sleep and their relation to bedtimes. Regular SP experiencers (N = 348) who had previously filled out a screening assessment for SP as well as a general sleep survey were recruited. Participants reported, online over the World Wide Web, using a standard reporting form, bedtimes and subsequent latencies of spontaneous episodes of SP occurring in their homes shortly after their occurrence. The distribution of SP episodes over nights was skewed to the first 2 h following bedtime. Just over one quarter of SP episodes occurred within 1 h of bedtime, although episodes were reported throughout the night with a minor mode around the time of normal waking. SP latencies following bedtimes were moderately consistent across episodes and independent of bedtimes. Additionally, profiles of SP latencies validated self-reported hypnagogic, hypnomesic, and hypnopompic SP categories, as occurring near the beginning, middle, and end of the night/sleep period respectively. Results are consistent with the hypothesis that SP timing is controlled by mechanisms initiated at or following sleep onset. These results also suggest that SP, rather than uniquely reflecting anomalous sleep-onset rapid eye movement (REM) periods, may result from failure to maintain sleep during REM periods at any point during the sleep period. On this view, SP may sometimes reflect the maintenance of REM consciousness when waking and SP hallucinations the continuation of dream experiences into waking life.

Despite considerable growth in the field of brain-computer or brain-machine interface (BCI/BMI) research reflected in several hundred publications each year, little progress was made to enable patients in complete locked-in state (CLIS) to reliably communicate using their brain activity. Independent of the invasiveness of the BCI systems tested, no sustained direct brain control and communication was demonstrated in a patient in CLIS so far. This suggested a more fundamental theoretical problem of learning and attention in brain communication with BCI/BMI, formulated in the extinction-of-thought hypothesis. While operant conditioning and goal-directed thinking seems impaired in complete paralysis, classical conditioning of brain responses might represent the only alternative. First experimental studies in CLIS using semantic conditioning support this assumption. Evidence that quality-of-life in locked-in-state is not as limited and poor as generally believed draise doubts that "patient wills" or "advanced directives"signed long-before the locked-in-state are useful. On the contrary, they might be used as an excuse to shorten anticipated long periods of care for these patients avoiding associated financial and social burdens. Current state and availability of BCI/BMI systems urge a broader societal discourse on the pressing ethical challenges associated with the advancements in neurotechnology and BCI/BMI research.

Hypokalemic periodic paralysis (hypoKPP) is an autosomal dominant skeletal muscle disorder manifested by episodic weakness associated with low serum potassium. Genetic linkage analysis has localized the hypoKPP gene to chromosome 1q31-q32 near a dihydropyridine receptor (DHP) gene. This receptor functions as a voltage-gated calcium channel and is also critical for excitation-contraction coupling in a voltage-sensitive and calcium-independent manner. We have characterized patient-specific DHP receptor mutations in 11 probands of 33 independent hypoKPP kindreds that occur at one of two adjacent nucleotides within the same codon and predict substitution of a highly conserved arginine in the S4 segment of domain 4 with either histidine or glycine. In one kindred, the mutation arose de novo. Taken together, these data establish the DHP receptor as the hypoKPP gene. We are unaware of any other human diseases presently known to result from DHP receptor mutations.

Two characteristic cases encountered in young adults led the authors to present the hand foot and mouth syndrome. They report the characteristic distribution and vesicular appearance of the lesions. The course was benign. The viral origin of the disease was more or less easily confirmed by cell culture, inoculation in new born mice and demonstration of antibodies. Usually the virus was a Coxackie A 16. However in one of the authors cases, an Echo 11 was demonstrated. The apparent rareness of the disease may be explained by lack of recognition.

A prospective randomised study on 70 volunteers without previous first aid education (42 males, 28 females, mean age 17) was performed to compare mouth-to-mouth ventilation (MMV, n = 24) versus mouth-to-pocket-mask ventilation (MPV, n = 25) and mouth-to-face-shield ventilation (MFV, n =21), and to evaluate if an instruction period of 10 min would be sufficient to teach lay persons artificial ventilation. Every volunteer performed three ventilation series using a bench model of an unprotected airway. MMV and MPV show higher mean tidal volume (TV) than MFV (values of series 3: 976 +/- 454 and 868 +/- 459 versus 604 +/- 328 ml, P = 0.002 and P = 0.025, respectively). We found a higher inter-individual variation in TV than in previous studies (P = 0.031). The recommended TV of 700-1000 ml was reached in only 23%, most frequently with MPV (MMV 16.7%, MPV 32%, MFV 19%) but the difference was not significant (P = 0.391). However, we found a significantly higher percentage with a TV below 700 ml with MFV (MMV 33.3%, MPV 36%, MFV 66.7% P = 0.047) and a significantly higher percentage of TV exceeding 1000 ml with MMV (MMV 50%, MPV 32%, MFV 14.3%) (P = 0.039). "Stomach" inflation was highest with MMV (79.2%) followed by MPV (52%) and MFV (42.9%) (P = 0.034). We found further differences between the sexes; males produced a higher TV (P = 0.003) and a higher percentage of stomach inflation (P = 0.029). MPV showed the best ventilation quality. It resulted in a more adequate TV than MMV and MFV and lower stomach inflation than MMV. Only a relatively low percentage of ventilations were within the recommended range for TV and this may be related to the short training duration. We found different performances between the sexes, a high inter-individual variation and mainly a low ventilation quality. Therefore, further studies have to focus more on teaching duration, sex differences and ventilation quality.

Bilateral vocal fold paralysis (BVFP) is characterized by fold immobility in complete adduction or abduction, secondary to a vagus nerve lesion, through the recurrent laryngeal nerve. The manifestation is variable dyspnea and stridor, fatal if the airway is not secured. There are endolaryngeal and extralaryngeal techniques to increase the glottic opening, improving ventilation and deglutition, and the possibility of decannulation and phonation. Case series consisting of BVFP patients, treated with posterior cordectomy, from January 2004 to January 2010. Clinical charts were reviewed to obtain data and registries of presurgical and postsurgical control endolaryngoscopies. Nineteen patients were identified. Twelve (63.2 %) had a tracheotomy cannula in place, and seven (36.8 %) didn't. Total thyroidectomy was the principal cause of the BVFP in 17 patients (89.5 %). A right cordectomy was performed on 10 patients (52.6 %). At 12 months, endolaryngoscopy detected a 40.26 % average increase in the glottic opening (p < 0.05), allowing for decannulation in 10 (83.3 %) of the tracheotomy patients. Laser cordectomy is a simple procedure for the treatment of BVFP, with few complications, permitting oronasal ventilation, decannulation and phonation.

Acute hypokalemic paralysis is a rare and potentially fatal condition, with few related causes, one of which highlights distal renal tubular acidosis (dRTA). Distal renal tubular acidosis is a rare complication of several autoimmune diseases such as systemic lupus erythematosus, Sjögren’s syndrome, and Hashimoto thyroiditis. We report a case of a lupic patient who presented rapidly progressive quadriparesis in the context of active renal disease. Research revealed severe refractory hypokalemia, metabolic acidosis, and alkaline urine suggestive of dRTA. We diagnosed Sjögren’s syndrome based on sicca symptoms, an abnormal salivary glands’ nuclear scan and the presence of anti-Ro/SSA and anti-La/SSB. In addition, the finding of thyroid peroxidase, thyroglobulin antibodies, and hypothyroidism led us to the diagnosis of Hashimoto thyroiditis. Due to the active renal involvement on the context of systemic lupus erythematosus and Sjögren’s syndrome, the patient received immunosuppression with rituximab, resulting in a progressive and complete improvement.

To investigate the relationship between abnormal swallowing and mouth breathing. Thirty-eight patients with abnormal swallowing and 38 patients with normal swallowing were selected. All patients presented with no airway constriction. The age range of the patients was 11-14 years old. The number of patients with mouth breathing was calculated. Statistical analysis (χ(2) test) was performed. The number of patients with mouth breathing in the abnormal swallowing group (17, 45%) was significantly higher than that in the normal swallowing group (5, 13%) (χ(2) = 9.212, P = 0.002). Abnormal swallowing was related to mouth breathing.

Menopause is a physiological process typically occurring in the fifth decade of life. One of the most annoying oral symptoms in this age group is the burning mouth syndrome (BMS), which may be defined as an intraoral burning sensation occurring in the absence of identifiable oral lesion or laboratory findings. Pain in burning mouth syndrome may be described as burning, tender, tingling, hot, scalding, and numb sensation in the oral mucosa. Multiple oral sites may be involved, but the anterior two-third part and the tip of tongue are most commonly affected site. There is no definite etiology for BMS other than the precipitating causative factors, and it is still considered idiopathic. Various treatment options like use of benzodiazepine, anti-depressants, analgesics, capsaicin, alpha lipoic acids, and cognitive behavioral therapy are found to be effective, but definite treatment is still unknown. The present article discusses some of the recent concepts of etiopathogenesis of BMS as well as the role of pharmacotherapeutic management in this disorder. PMID:23411996

Mouth rinsing with a CHO solution has been suggested to improve short (<1 h) endurance performance through central effect. We examined the effects of mouth rinsing with a CHO solution on running time to exhaustion on a treadmill. Six well-trained subjects ran to exhaustion at 85% VO2max , on three separate occasions. Subjects received either an 8% CHO solution or a placebo (PLA) every 15 min to mouth rinse (MR) or a 6% CHO solution to ingest (ING). Treatments were assigned in a randomized, counterbalanced fashion, with the mouth-rinsing treatments double-blinded. Blood samples were taken to assess glucose (Glu) and lactate (Lac), as well as the perceived exertion (RPE). Gas exchange and heart rate (HR) were collected during all trials. Subjects ran longer (P = 0·038) in both the MR (2583 ± 686 s) and ING (2625 ± 804 s) trials, compared to PLA (1935 ± 809 s), covering a greater distance (MR 9685 ± 3511·62 m; ING 9855 ± 4118·62; PLA 7295 ± 3727 m). RER was significantly higher in both ING and MR versus PLA. No difference among trials was observed for other metabolic or cardiovascular variables (VO2 , Lac, Glu, HR), nor for RPE. Endurance capacity, based on time to exhaustion on a treadmill, was improved when either mouth rinsing or ingesting a CHO solution, compared to PLA.

This review summarizes the empirical and clinical literature on sleep paralysis most relevant to practitioners. During episodes of sleep paralysis, the sufferer awakens to rapid eye movement sleep-based atonia combined with conscious awareness. This is usually a frightening event often accompanied by vivid, waking dreams (ie, hallucinations). When sleep paralysis occurs independently of narcolepsy and other medical conditions, it is termed "isolated" sleep paralysis. Although the more specific diagnostic syndrome of "recurrent isolated sleep paralysis" is a recognized sleep-wake disorder, it is not widely known to nonsleep specialists. This is likely due to the unusual nature of the condition, patient reluctance to disclose episodes for fear of embarrassment, and a lack of training during medical residencies and graduate education. In fact, a growing literature base has accrued on the prevalence, risk factors, and clinical impact of this condition, and a number of assessment instruments are currently available in both self-report and interview formats. After discussing these and providing suggestions for accurate diagnosis, differential diagnosis, and patient selection, the available treatment options are discussed. These consist of both pharmacological and psychotherapeutic interventions which, although promising, require more empirical support and larger, well-controlled trials.

The objective of this study was to analyze some clinical and epidemiologic aspects, as well as the follow up of 180 patients with Bell's palsy. In the study population there was a predominance of female (66.7%). Two peaks of incidence in the age distribution were identified: third-fourth and sixth decades of life. In the group of 180 patients there were 198 events of facial paralysis, 17 recurrences and in one patient the paralysis was bilateral at the onset. In 15 patients (8.3%) there were recurrences of the facial paralysis, in 12 cases (70.6%) the recurrences were ipsilateral. The left side of the face was involved in 55.6% of the cases. In eight patients the paralysis occurred during pregnancy (n=5) or puerperium (n=3). As associated conditions we found: arterial hypertension (11.7%), diabetes mellitus (11.1%), pregnancy or puerperium (4.4%; 6.7% in the women), and neurocysticercosis (1.1%). In 72.8% of the cases no association with such conditions was found. In 22.8% of the patients some kind of sequelae were identified: hemifacial spasm (12.8%), partial recovery of the motor deficit (10.6%), syndrome of the crocodile tears (3.3%), sincinetic contraction (2.8%), and the Marcus Gunn inverse phenomenon (1.1%). In conclusion, this study shows that the idiopathic facial paralysis may lead to important sequelae in more than 20% of the patients.

This paper describes a syndrome of psychological and physical symptoms involving body paralysis and hallucinations traditionally interpreted in Newfoundland as an attack of 'Old Hag'. Folk theories of cause and treatment are outlined based on 13 months of field research in a community on the northeast coast of Newfoundland. Data derived from the responses of 69 adults to the Cornell Medical Index (CMI) indicate that there are no significant differences in psychological or physical illness complaints between adults who have experienced the Old Hag and adults who have not had this experience. The striking similarity between the Old Hag experience and a clinical condition called sleep paralysis is analyzed, and the implications of viewing the Old Hag as sleep paralysis are discussed within the context of current theoretical issues in transcultural psychiatry.

The Waterloo Sleep Experiences Scale was developed to assess the prevalence of sleep paralysis and a variety of associated hypnagogic and hypnopompic hallucinoid experiences: sensed presence, felt pressure, floating sensations, auditory and visual hallucinations, and fear. Consistent with results of recent surveys, almost 30% of 870 university students reported at least one experience of sleep paralysis. Approximately three-quarters of those also reported at least one hallucinoid experience, and slightly more than 10% experienced three or more. Fear was positively associated with hallucinoid experiences, most clearly with sensed presence. Regression analyses lend support to the hypothesis that sensed presence and fear are primitive associates of sleep paralysis and contribute to the elaboration of further hallucinoid experiences, especially those involving visual experiences.

Bell's palsy or idiopathic facial paralysis is the most common cause of unilateral facial paralysis. This case report describes a patient referred for physical therapy evaluation and treatment with a diagnosis of Bell's palsy. On initial presentation in physical therapy the patient had unilateral facial paralysis, ipsilateral regional facial pain and numbness, and a history of a gradual, progressive onset of symptoms. The process of evaluating this patient in physical therapy, as well as the recognition of signs and symptoms typical and atypical of Bell's palsy, are described. This report emphasizes the importance of early recognition of the signs and symptoms inconsistent with a diagnosis of Bell's palsy, and indications for prompt, appropriate referral for additional diagnostic services.

To provide interested scholars with a historical perspective of facial paralysis as interpreted by the ceramists of the ancient Moche culture. The authorities and curators of the Museo Arqueológico Rafael Larco Herrera, and the Museo Nacional de Arqueología, Antropología e Historia del Perú, in Lima, Perú, provided photographs of some of the more salient examples of facial paralysis in their Moche ceramic collections. Four of these were selected for inclusion in this article. Moche pathologic portraits establish a unique point of reference in the history of facial paralysis and its sequelae. They stand alone as a prehistoric record of this disorder, unsurpassed until the appearance of Bell's work and illustrations.

Professor Sun Liuhe is engaged in medical service for over 40 years. He is deeply involved in research on intractable and complicated diseases. Especially, in treating facial paralysis, he makes diagnosis and treatment based on overall analysis of symptoms and causes, differentiation of syndrome for etiology. Without confining himself to ancient treatment methods, by applying both acupuncture and Chinese medicine, selecting auxiliary acupoints according to differentiation of meridians related to illness, as well as considering anatomy. Professor Sun holds ancient and modern therapeutic methods, brings forth ideas of using new acupoints to prevent perversion based on pulse tracings, and uses cutting therapy for the cases suffering from facial paralysis for a long time. This method can shorten treatment courses, to a great extent, and achieve good therapeutic effects on intractable facial paralysis, which has revealed distinctness of acupuncture therapy.

A15-year-old girl who developed traumatic iliacus hematoma and complete paralysis of the quadriceps muscle is reported. The current case and literature review revealed that incomplete quadriceps paralysis associated with traumatic iliacus hematoma is likely to progress to complete paralysis in days or weeks as a result of increased intracompartmental pressure. However, surgical decompression of the femoral nerve could produce good results even in patients who have complete quadriceps paralysis preoperatively.

Two children were admitted to a medical centre due to dehydration after an oral injury and the extraction of a tooth. One child complained of "mouth broken". Dehydration is the most common water-electrolyte imbalance in children. Babies and young children are prone to dehydration due to their relatively large body surface area, the high percentage extracellular fluid, and the limited ability of the kidneys to conserve water. After the removal ofa tooth, after an oral trauma or in case of oral discomfort, a child is at greater risk of dehydration by reduced fluid and food intake due to oral pain and/or discomfort and anxiety to drink. In those cases, extra attention needs to be devoted to the intake of fluids.

Intralaryngeal electrostimulation of the laryngeal muscles with fluctuating currents with simultaneous mobilization of the arytenoid cartilage and paralysed vocal cord were used in 42 patients with unilateral laryngeal paralysis. The treatment was combined with phonopedic lessons. The control group consisted of 32 patients receiving standard electrostimulation with diadynamic currents. The effect was evaluated by changes in vocal acoustic parameters and stroboscopic parameters. In patients with paramedian fixation of the vocal cords voice improvement was obtained irrespective of electrostimulation type. For patients with intermedian and lateral fixation of the vocal cords more effective was intralaryngeal electrostimulation with fluctuating currents. A good therapeutic effect was achieved in patients with dislocation of the arytenoid cartilage.

Introduction Diaphragmatic eventration is a congenital defect of the muscular portion of a hemidiaphragm that eventually leads to hemidiaphragmatic elevation and dysfunction. The clinical diagnosis of diaphragmatic eventration or diaphragmatic paralysis may be indistinguishable and diaphragmatic plication is the treatment of choice for both conditions. Discussion We review the indications, patient selection, and surgical techniques for diaphragmatic plication. We explain our preferred technique and guide the reader step by step on our approach. Conclusion Minimally invasive diaphragm plication techniques are effective alternatives to open transthoracic plication and result in significant improvement in dyspnea and quality of life in adequately selected patients.

It has been proved by clinical experiment that needling at Fengchi (GB 20), Wangu (GB 12) and Tianzhu (BL 10) can markedly improve the blood supply to the vertebral basilar artery, increase the cerebral blood flow, and relax the spasm of the vascular smooth muscles. The combined use of Shangxing (GV 23) and Yintang (EX-HN3) can give the effects of resuscitating and tranquilizing the mind, dispelling wind, dredging the channels, and relieving spasm and pain. In short, the above therapy may turn the pathological state into a normal physiological state, and bring a quicker recovery for patients with facial spasm, trigeminal neuralgia and stubborn facial paralysis.

OBJECTIVES—The occurrence of a lingual paralysis after unilateral upper motor neuron lesions is an infrequent clinical phenomenon, and the underlying pathophysiological mechanisms are poorly understood. We studied the cortical motor representations of ipsilateral and contralateral lingual muscles in healthy controls and in a selected group of stroke patients, to clarify the variable occurrence of a lingual paralysis after recent monohemispheric ischaemia. METHODS—A special bipolar surface electrode was used to record the ipsilateral and contralateral compound muscle action potentials (CMAPs) from the lingual muscles after transcranial magnetic stimulation (TMS) of the human motor cortex and peripheral electrical stimulation (PES) of the hypoglossal nerve medial to the angle of the jaw. Four patients with a lingual paralysis (group 1) and four patients with symmetric lingual movements (group 2) after monohemispheric first ever stroke were studied and compared with 40 healthy controls. RESULTS—In controls, TMS of either hemisphere invariably produces CAMPs in the ipsilateral and contralateral lingual muscles, elicited through crossed and uncrossed central motor pathways, respectively. In the 40 healthy controls, TMS of either hemisphere elicited CMAPs of significantly greater amplitudes and shorter onset latencies from the contralateral muscles compared with the ipsilateral responses (p<0.0001). In the patient groups, TMS of the affected hemisphere failed to evoke any CMAP from either lingual side; TMS of the unsevered hemisphere always produced normal ipsilateral and contralateral responses, irrespective of whether the ipsilateral muscles were paralysed or not. CONCLUSIONS—Bilateral crossed and uncrossed corticonuclear projections are invariably existent in humans. After unilateral interruption of these pathways, some people do exhibit a lingual paralysis whereas others do not. The development of a central lingual paralysis is most likely dependent on

The phrenic nerve is the only motor nerve in the diaphragm. The injury will lead to a diaphragmatic paralysis or eventration with paradoxical movements during breathing. The aim of this review is to analyze the diagnostic criteria, surgical indications, and the patients that are not treated by surgery. We review 53 cases with diaphragmatic pathology in the last 5 years; 19 females and 20 males. One was a diaphragmatic rupture, 13 were diaphragmatic hernias, and 39 had diaphragmatic paralysis. Diaphragmatic paralysis was diagnosed by fluoroscopy in 97%, electromiography 5.1% or ultrasounds. The ethiology was 64% after cardiac surgery and 10% after thoracic oncologic surgery. The age at diagnosis was less than 1 month in 41% cases. In 29 patients the paralysis was well tolerated and were extubated between 24 h and 4 days after the diagnosis, frequently was in the first 48 h. 4 patients need a traqueostomy and 2 went to another hospital. In 5 we performed a diaphragmatic plication because the inability to be extubated or the persistence of respiratory distress. The paralysis was demonstrated by fluoroscopy. 2 patients are asymptomatic, 2 are in mechanical ventilation and 1 died (sepsis). The most frequent cause of diaphragmatic paralysis was related to cardiac or thoracic surgery. In general, is well tolerated, almost asymptomatic, the patients were extubated between 24 or 48 h. In pediatric population they are few cases that need surgical treatment. The patients that we operated on were less than 2 months old, because is at that age were the repercussion is more important. We must follow strict criteria, without precipìtation for the surgical indications.

Enteroviruses (EVs) are important human pathogens associated with various clinical syndromes. This study represents an overview of non-polio enteroviruses (NPEVs) isolated from acute flaccid paralysis (AFP) surveillance in Shandong Province, China from 1988 to 2013. Altogether 792 and 170 NPEV isolates were isolated from stool specimens of 9263 AFP cases and 1059 contacts, respectively. Complete VP1 sequencing and typing on all 962 isolates revealed 53 NPEV types in which echovirus (E) 6 (7.6%), E14 (7.6%), E11 (7.4%), coxsackievirus (CV) B3 (7.4%), E25 (5.6%), CVB5 (4.9%), E7 (4.5%) and EV-A71 (4.4%) were the eight most commonly reported serotypes. Distinct summer-fall seasonality was observed, with June-October accounting for 79.3% of isolation from AFP cases with known month of specimen collection. Increase of isolation of EV-A71 and CVA--the predominant pathogens for the hand, foot, and mouth disease--was observed in recent years. Sequence analysis on VP1 coding region of EV-A71 and E6 suggested Shandong strains had great genetic divergence with isolates from other countries. The results described in this study provide valuable information on the circulation and emergence of different EV types in the context of limited EV surveillance in China.

Lightning injury is the second most common cause of weather-related deaths in the United States. Despite the several neurological complications such as polyneuropathy, myelopathy, spinal cord injury, motor neuron disease due to the lightning-induced injury, there is no documented case of unilateral diaphragmatic paralysis. We describe the case of a patient with a history of lightning strike at childhood period, prior the onset of isolated, diaphragmatic paralysis, unilaterally. Clinical and electrophysiological findings suggest an injury restricted to the phrenic nerve, unilaterally. PMID:24765394

A case of severe miastenia beginning with dyspnea, secondary to a bilateral larynx paralysis in aduction is presented. During the evolution of the severe miastenia the affectation of the larynx musculature does not result infrequent, but however, after having realized a bibliographic revision, the infrequency resulting in this disease of the beginning through a bilateral larynx paralysis in aduction was verified. A wide exposition of the clinic case, methods of exploration to obtain the diagnosis of severe miastenia, and the different treatment options actually in use to control these disease, are realized.
It is suggested that picturesque medical conditions can, at times, be encountered in literary works composed prior to their clinical delineation. This is true of sleep paralysis, of which the first scientific description was given by Silas Weir Mitchell in 1876. A quarter of a century earlier, Herman Melville, in Moby-Dick, gave a precise account of a case, including the predisposing factors and sexual connotations, all in accord with modern theory. The details of Ishmael's attack of sleep paralysis, the stresses leading up to it, and the associations causing him to recall the experience are given here.

We report the case of a 73-year-old woman who complained of acute onset of pain and weakness of her left shoulder and proximal arm muscles 3 weeks after a diagnosis of herpes zoster. Electromyography revealed involvement of the C5-6 myotomes and the upper trunk of the brachial plexus. Chest X-ray and electromyographic studies documented paralysis of the left diaphragm. One year after onset, muscle strength returned to normal, but radiographic and electrophysiologic findings of diaphragm paralysis were unchanged.

We report a case of a median nerve palsy. Hepatic segmentectomy and lymphnode dissection were performed in a 21-year-old man for multiple liver and retroperitoneal lymph nodes metastasis of seminoma. After surgery, patient complained of motor paralysis and hypesthesia of the left palm side of the thumb, first finger and radial half of the middle finger. He was diagnosed as having median nerve palsy. Motor paralysis and hypesthesia gradually disappeared over the two weeks after surgery. We should pay attention to appropriate positioning of the arm during surgery, and preoperative use of paclitaxel needs to be considered as etiology for perioperative peripheral nerve palsy.

Bell's palsy is an acute facial paralysis of unknown etiology. Infections including syphilis have been implicated as causes for peripheral facial paresis. The Jarisch-Herxheimer reaction is an acute worsening of skin manifestations and systemic symptoms occurring after administration of antimicrobial therapy for spirochetal infections. Although rare, neurological signs can present as part of the Jarisch-Herxheimer reaction. The authors report a case of Bell's palsy experienced by a patient shortly after treatment with penicillin for secondary syphilis and propose that this acute unilateral peripheral facial paralysis was a Jarisch-Herxheimer reaction in response to therapy.

Facial paralysis is a clinical entity associated with significant morbidity, which has a treatment paradigm that is continually evolving. Surgical management of the paralyzed face poses significant challenges to achieve the goal of returning patients to their premorbid states. Here we attempt to review the advances in facial reanimation, in particular with regards to chronic facial paralysis. These include recent developments in static and dynamic rehabilitation including advances like artificial muscles for eyelid reconstruction, dynamic muscle transfer for the eye, and orthodromic temporalis tendon transfer.

A wide variety of neurological manifestations are known in patients with diabetes mellitus. We describe a 40-year-old man who presented with hypokalemic paralysis. On evaluation, we found that the cause of the hypokalemia was osmotic diuresis induced by marked hyperglycemia due to undiagnosed diabetes mellitus. The patient had an uneventful recovery with potassium replacement, followed by glycemic control with insulin. Barring a few instances of symptomatic hypokalemia in the setting of diabetic emergencies, to our knowledge uncomplicated hyperglycemia has not been reported to result in hypokalemic paralysis.

To evaluate the therapeutic effect and safety of acupoint sticking therapy for facial paralysis. Search the literatures in the whole paper databank of China figure medical library (Jan. 1994-Dec. 2004) and China Biomedical Literature Disk Databank (Jan. 1995-Dec. 2004). Meta-analysis was conducted with RevMan 4. 2. 5 software. Sixteen controlled trials involving 2 157 patients were included. Meta-analysis indicated that there was high statistically difference between the acupoint sticking therapy and simple acupuncture therapy or Western medicine therapy. The acupoint sticking therapy is effective and safe for facial paralysis.

Timely mouth-to-mouth ventilation is critical to resuscitate drowning victims. While drowning is frequent, there are no lay persons trained in cardio-pulmonary resuscitation (CPR) in rural Bangladesh. As part of a feasibility study to create a first response system in a conservative Islamic village environment, a pilot was undertaken to examine willingness to provide mouth-to-mouth ventilation for drowning resuscitation. A questionnaire was administered to 721 participants at the beginning of a village-based CPR training course. Trainees were asked regarding willingness to administer mouth-to-mouth ventilation on a variety of hypothetical victims. Responses were tabulated according to the age, sex and relationship of the trainee to the postulated victim. Willingness to deliver mouth-to-mouth ventilation was influenced by sex of a potential recipient and relationship to the trainee. Adolescent participants were significantly more willing to perform mouth-to-mouth ventilation on someone of the same sex. Willingness increased for both sexes when the postulated victim was an immediate family member. Willingness was lower with extended family members and lowest with strangers. Adult trainees were more likely to perform mouth-to-mouth ventilation than adolescent trainees in any scenario. Adults express more willingness to resuscitate a broader range of drowning victims than adolescents. However in rural Bangladesh, adolescents are more likely to be in close proximity to a drowning in progress. Further efforts are needed to increase willingness of adolescents to provide resuscitation to drowning victims. However, despite potential cultural limitations, trained responders appear to be willing to give mouth-to-mouth ventilation to various recipients. Final determination will require evidence on response outcomes which is being collected.

To analyze the long-term objective, perceptive, and subjective outcomes after endoscopic polydimethylsiloxane (PDMS) injection laryngoplasty in unilateral vocal fold paralysis. A retrospective study carried out between January 2008 and January 2012. Head and Neck Department, University Hospital of Modena, Modena, Italy. This was a retrospective analysis of 26 patients with unilateral vocal fold paralysis who underwent endoscopic injection of PDMS under general anesthesia. A voice evaluation protocol was performed for all patients, which included videolaryngostroboscopy, maximum phonation time, fundamental frequency, analysis of the harmonic structure of the vowel /a/ and the word /aiuole/, Grade of Dysphonia, Instability, Roughness, Breathiness, Asthenia, and Strain scale, and Voice Handicap Index. The protocol was performed before surgery, in the immediate postoperative period, and at least 3 years after surgery. The mean follow-up period was 73 months (range 39-119 months). The statistical analysis showed a significant improvement (P < 0.01) for all of the objective, perceptive, and subjective parameters by comparison between the preoperative and long-term follow-up data; moreover, no statistically significant difference was found between the postoperative and long-term follow-up data. This indicates that injection laryngoplasty with PDMS guarantees long-lasting effects over time. No complications were reported in our series. Injection laryngoplasty with PDMS can be considered to be a minimally invasive and safe technique for the treatment of unilateral vocal fold paralysis. Moreover, it allows very good and stable results to be obtained over time, avoiding repeated treatments and improving the quality of life of the patients. Copyright © 2017 The Voice Foundation.

To evaluate the effectiveness of the median nerve constrictive operation combined with tendon transfer to treat the brain paralysis convulsive deformity of the hand. The clinical data from 21 cases with brain paralysis convulsive deformity of the hand were analyzed retrospectively between August 2009 and April 2012. Of them, there were 13 males and 8 females with an average age of 15 years (range, 10-29 years). The causes of the convulsive cerebral palsy included preterm deliveries in 11 cases, hypoxia asphyxia in 7, traumatic brain injury in 2, and encephalitis sequela in 1. The disease duration was 2-26 years (mean, 10.6 years). All the 21 patients had cock waists, crooking fingers, and contracture of adductors pollicis, 12 had the forearm pronation deformity. According to Ashworth criteria, there were 2 cases at level I, 5 cases at level II, 8 cases at level III, 4 cases at level IV, and 2 cases at level V. All patients had no intelligence disturbances. The forearm X-ray film showed no bone architectural changes before operation. The contraction of muscle and innervation was analyzed before operation. The median nerve constrictive operation combined with tendon transfer was performed. The functional activities and deformity improvement were evaluated during follow-up. After operation, all the patients' incision healed by first intension, without muscle atrophy and ischemic spasm. All the 21 cases were followed up 1.5-4.5 years (mean, 2.3 years). No superficial sensory loss occurred. The effectiveness was excellent in 13 cases, good in 6 cases, and poor in 2 cases, with an excellent and good rate of 90.4% at last follow-up. The median nerve constrictive operation combined with tendon transfer to treat brain paralysis convulsive deformity of the hand can remove and prevent the recurrence of spasm, achieve the orthopedic goals, to assure the restoration of motor function and the improvement of the life quality.

Development of synkinesis, hypertonicity, and poor smile excursion after facial nerve insult and recovery contribute to disfigurement, psychological difficulties, and an inability to convey emotion via facial expression. Despite treatment with physical therapy and chemodenervation, some patients who recover from transient flaccid facial paralysis never spontaneously regain the ability to perform a meaningful smile. Prospective evaluation was performed on 20 patients with nonflaccid facial paralysis who underwent free gracilis muscle transfer. Patients were evaluated using the quality-of-life (QOL) FaCE survey, Facial Nerve Grading Scale, and Facegram to quantify QOL improvement, smile excursion, and symmetry after muscle transfer. A statistically significant increase in the FaCE score was seen after muscle transfer (paired 2-tailed t test, P < 0.039). In addition, there was a statistically significant improvement in the smile score on the Facial Nerve Grading Scale (P < 0.002), in the lower lip length at rest (P = 0.01) and with smile (P = 0.0001), and with smile symmetry (P = 0.0077) after surgery. Free gracilis muscle transfer has become a mainstay in the management armamentarium for patients who develop severe reduction in oral commissure movement after facial nerve insult and recovery. The operation achieves a high overall success rate, and innovations involving transplanting thinner segments of muscle avoid a cosmetic deformity secondary to excess bulk. This study demonstrates a quantitative improvement in QOL and facial function after free gracilis muscle transfer in patients who failed to achieve a meaningful smile after physical therapy.

To compare the efficacy, relapse, and adverse effects between intralesional injection and mouth rinse of triamcinolone acetonide (TA) in patients with oral lichen planus (OLP). A randomized controlled study. College medical center. Forty consecutive patients, who had been diagnosed with OLP, were recruited. Participants were randomly divided into 2 groups using intralesional injection or mouth rinse of TA. The severity of pain and burning sensation on a 10-cm visual analog scale (VAS) and the Oral Health Impact Profile-14 (OHIP-14) were assessed at weeks 0, 1, 2, 3, 4, and 6. The signs of OLP were quantified using a special scoring system for OLP. The rate of relapse and the adverse effects were compared between both groups. The VAS scores for pain and burning mouth sensation and objective scoring for OLP were significantly improved at 1, 2, 3, 4, and 6 weeks in both groups. The changes in the VAS for burning mouth sensation, OHIP-14, and objective scoring for OLP were similar between both groups. The change in the VAS for pain from baseline to week 1 in the intralesional injection group was significantly higher than in the mouth rinse group. The rate of adverse effects was significantly higher in the mouth rinse group than in the intralesional injection group (44.4% vs 5.0%). The efficacies of both treatments were similar. The rate of adverse effects was significantly lower for intralesional injection of TA than mouth rinse of TA.

This study examined the effect of mouth breathing on the strength and duration of vertical effect on the posterior teeth using related functional parameters during 3 min of gum chewing in 39 nasal breathers. A CO(2) sensor was placed over the mouth to detect expiratory airflow. When no airflow was detected from the mouth throughout the recording period, the subject was considered a nasal breather and enrolled in the study. Electromyographic (EMG) activity was recorded during 3 min of gum chewing. The protocol was repeated with the nostrils occluded. The strength of the vertical effect was obtained as integrated masseter muscle EMG activity, and the duration of vertical effect was also obtained as chewing stroke count, chewing cycle variation and EMG activity duration above baseline. Baseline activity was obtained from the isotonic EMG activity during jaw movement at 1.6 Hz without making tooth contact. The duration represented the percentage of the active period above baseline relative to the 3-min chewing period. Paired t-test and repeated analysis of variance were used to compare variables between nasal and mouth breathing. The integrated EMG activity and the duration of EMG activity above baseline, chewing stroke count and chewing cycle significantly decreased during mouth breathing compared with nasal breathing (P<0.05). Chewing cycle variance during mouth breathing was significantly greater than nasal breathing (P<0.05). Mouth breathing reduces the vertical effect on the posterior teeth, which can affect the vertical position of posterior teeth negatively, leading to malocclusion.

The present prognosis for the recovery of voluntary control of movement in patients diagnosed as motor complete is generally poor. Herein we introduce a novel and noninvasive stimulation strategy of painless transcutaneous electrical enabling motor control and a pharmacological enabling motor control strategy to neuromodulate the physiological state of the spinal cord. This neuromodulation enabled the spinal locomotor networks of individuals with motor complete paralysis for 2-6 years American Spinal Cord Injury Association Impairment Scale (AIS) to be re-engaged and trained. We showed that locomotor-like stepping could be induced without voluntary effort within a single test session using electrical stimulation and training. We also observed significant facilitation of voluntary influence on the stepping movements in the presence of stimulation over a 4-week period in each subject. Using these strategies we transformed brain-spinal neuronal networks from a dormant to a functional state sufficiently to enable recovery of voluntary movement in five out of five subjects. Pharmacological intervention combined with stimulation and training resulted in further improvement in voluntary motor control of stepping-like movements in all subjects. We also observed on-command selective activation of the gastrocnemius and soleus muscles when attempting to plantarflex. At the end of 18 weeks of weekly interventions the mean changes in the amplitude of voluntarily controlled movement without stimulation was as high as occurred when combined with electrical stimulation. Additionally, spinally evoked motor potentials were readily modulated in the presence of voluntary effort, providing electrophysiological evidence of the re-establishment of functional connectivity among neural networks between the brain and the spinal cord.

, independent of the treatment regimen. In the Bell's paralysis group, 38 patients (70%) recovered completely after 1 year, including 94% of patients with a denervation by ENoG of less than 90%. Thirty percent of Bell's paralysis patients recovered incompletely, revealing the worst outcome in patients with a 100% denervation on ENoG. None of the 4 patients with HZO and ENoG denervation of more than 90% recovered to normal facial function. We found a highly significant difference regarding the time course and final outcome in patients with incomplete palsies versus total paralysis; however, only 3 of 250 studies make this distinction. The time course for improvement and the extent of recovery is significantly different in patients presenting with an incomplete facial nerve paresis compared with patients with a total paralysis. Whereas the term "palsy" includes both entities, the term "paralysis" should only be used to describe total loss of nerve function. Patients with incomplete acute Bell's palsy (paresis) should start to improve their facial function early (1-2 wk after onset) and are expected to recover completely within 3 months. These patients do not benefit from antiviral medications and most likely do not profit from systemic steroids. Mixing patients with different severity of palsies will always lead to controversial results.

This review summarizes the empirical and clinical literature on sleep paralysis most relevant to practitioners. During episodes of sleep paralysis, the sufferer awakens to rapid eye movement sleep-based atonia combined with conscious awareness. This is usually a frightening event often accompanied by vivid, waking dreams (ie, hallucinations). When sleep paralysis occurs independently of narcolepsy and other medical conditions, it is termed “isolated” sleep paralysis. Although the more specific diagnostic syndrome of “recurrent isolated sleep paralysis” is a recognized sleep–wake disorder, it is not widely known to nonsleep specialists. This is likely due to the unusual nature of the condition, patient reluctance to disclose episodes for fear of embarrassment, and a lack of training during medical residencies and graduate education. In fact, a growing literature base has accrued on the prevalence, risk factors, and clinical impact of this condition, and a number of assessment instruments are currently available in both self-report and interview formats. After discussing these and providing suggestions for accurate diagnosis, differential diagnosis, and patient selection, the available treatment options are discussed. These consist of both pharmacological and psychotherapeutic interventions which, although promising, require more empirical support and larger, well-controlled trials. PMID:27486325

To analyze the predictive value of electromyography (EMG) after peripheral vocal cord paralysis and to estimate regeneration time. Retrospective study based on electromyographic data and medical chart review of university based ENT hospitals. EMG results of 448 patients were classified into neuropraxia, axonotmesis/neurotmesis, or not classifiable and followed until final outcome. Final outcome was classified electromyographically into restitutio ad integrum, defective healing, or not classifiable. The etiology of the paralysis was thyroid gland surgery in 42.9% and other iatrogenic lesions in 11.8%. Idiopathic paralysis was found in 20.3%. Mean follow-up time was 4.8 months. Initial EMG findings were neuropraxia in 31.0%, axonotmesis/neurotmesis in 40.8%, and not classifiable in 28.1%. Restitutio ad integrum was detected by EMG in 17.6% and defective healing in 43.3%. In 39.1%, the outcome could not be classified. The positive predictive value of EMG was 97% and the negative predictive value 60%. The outcome depended significantly on the initial EMG result (P < .0001) but not on the etiology (P = .737) of the paresis. Regeneration time after neuropraxia was 4.0 months and after axonotmesis/neurotmesis 5.6 months. Laryngeal EMG has a high predictive value for acute peripheral vocal cord paralysis. The outcome can be predicted more reliably by means of EMG than by analysis of the etiology of the lesion.

Conversion paralysis is characterized by a loss of voluntary motor functioning without an organic cause. Despite its prevalence among neurological outpatients, little is known about the neurobiological basis of this motor dysfunction. We have examined whether the motor dysfunction in conversion paralysis can be linked to inhibition of the motor system, or rather to enhanced self-monitoring during motor behavior. We measured behavioral and cerebral responses (with fMRI) in eight conversion paralysis patients with a lateralized paresis of the arm as they were engaged in imagined actions of the affected and unaffected hand. We used a within-subjects design to compare cerebral activity during imagined movements of the affected and the unaffected hand. Motor imagery of the affected hand and the unaffected hand recruited comparable cerebral resources in the motor system, and generated equal behavioral performance. However, motor imagery of the affected limb recruited additional cerebral resources in the ventromedial prefrontal cortex and superior temporal cortex. These activation differences were caused by a failure to de-activate these regions during movement imagery of the affected hand. These findings lend support to the hypothesis that conversion paralysis is associated with heightened self-monitoring during actions with the affected arm.

The authors report four patients with a syndrome of painless bilateral isolated phrenic neuropathy. Electrophysiologic testing demonstrated active denervation restricted to the diaphragm. Long-term recovery was poor. The authors conclude that bilateral isolated phrenic neuropathy is a cause of painless diaphragmatic paralysis distinguishable from immune brachial plexus neuropathy and other neuromuscular disorders with similar clinical presentation.

Objective: Cruciate paralysis is a rare, poorly understood condition of the upper craniovertebral junction that allows for selective paralysis of the upper extremities while sparing the lower extremities. Reported cases are few and best treatment practices remain up for debate. The purpose of this study was to conduct a systemic literature review in an attempt to identify prognostic predictors and outcome trends associated with cases previously reported in the literature. Materials and Methods: We conducted a systematic literature review for all cases using the term “Cruciate Paralysis,” reviewing a total of 37 reported cases. All outcomes were assigned a numerical value based on examination at the last follow-up. These numerical values were further analyzed and tested for statistical significance. Results: Of the 37 cases, 78.4% were of traumatic causes. Of these, there were considerably worse outcomes associated with patients over the age of 65 years (P < 0.001). Those patients undergoing surgical treatment showed potentially worse outcomes, with a P value approaching significance at P = 0.08. Conclusion: Numerous cases of trauma-associated cruciate paralysis have been reported in the literature; however, there remains a strong need for further study of the condition. While certain risk factors can be elicited from currently reported studies, insignificant data exist to make any sound conclusion concerning whether surgical intervention is always the best method of treatment.

The treatment of 100 cases of acute stage peripheral facial paralysis with electro-acupuncture has indicated that, with the stimulation intensity and time interval strictly controlled, electro-acupuncture is effective. Suitable wave forms and electric intensity, as well as proper needling techniques and controlled duration of the stimulation according to experimental experience have yielded high therapeutic effects without aggravation of symptoms.
The estimated incidence of acute facial paralysis is approximately 30 patients per 100000 populations annually. Facial paralysis is an extremely frightening situation and gives extreme stress to patients because obvious disfiguring face may cause significant functional, aesthetic, and psychological disturbances. For stressful patients with acute facial paralysis, it is very important for clinicians to answer the questions like whether or not their facial function will return to normal, how much of their facial function will be recovered, and how long this is going to take. It is also important for clinicians to treat the psychological aspects by adequately explaining the prognosis, in addition to providing the appropriate medical treatment. For decades, clinicians have used various electrophysiologic tests, including the nerve excitability test, the maximal stimulation test, electroneurography, and electromyography. In particular, electroneurography is the only objective measure that is useful in early stage of acute facial paralysis. In this review article, we first discuss the pathophysiology of injured peripheral nerve. And then, we describe about various electrophysiologic tests and discuss the electroneurography extensively.

To optimize the acupuncture treatment programs for facial paralysis. Sixty-three patients of facial paralysis were randomly divided and treated according to the table of L9 (3)4 in orthogonal test. They were treated with different combined programs of 4 factors and 3 levels, including factor A (acupuncture op portunity), B (acupoints prescription), C (quantity of stimulus) and D (time of electroacupuncture). The change of facial nerve function score was observed to choose the best acupuncture treatment program for facial paralysis from factor A (acupuncture opportunity), B (acupoints prescription), C (quantity of stimulus), D (time of electroacupuncture) and their 3 levels in each factor. B (acupoints prescription) and D (time of electroacupuncture) were significant factors (P < 0.05), and B (acupoints prescription) was the most important influential factor. B3 (alternative use of two groups of acupoints) was the best one among the 3 levels of B (acupoints prescription), and D3 (electroacupuncture in disperse-dense wave for 30 min) was the best one of D (time of electroacupuncture). Two groups of acupoints alternatively used with electroacupuncture in disperse-dense wave for 30 min is the best treatment program for facial paralysis.

Antiseptic mouth rinses are widely recommended and marketed to improve oral health. This article summarizes current studies on the comparative effectiveness of selected antiseptic mouth rinses in controlling plaque and gingivitis, as well as risks associated with daily exposure, including salivary flow rate, oral cancer and wear of composite restorations. Electronic database searches were conducted using Google Scholar and PubMed to identify articles comparing the effectiveness of 4 commercially marketed antiseptic mouth rinses differing in active ingredients (0.12% chlorhexidine gluconate, essential oils (menthol, thymol and eucalyptol) and methyl salicylate, 0.7% cetylpyridinium chloride and 20% aloe vera gel) for controlling plaque and gingivitis. Criteria for inclusion included controlled clinical trials and systematic reviews appearing in English language publications evaluating the comparative effectiveness of the mouth rinses in controlling plaque and gingivitis, as well as risks associated with daily usage. The majority of studies have shown mouth rinses containing chlorhexidine gluconate or essential oils and methyl salicylate provide clinically significant anti-gingivitis and anti-plaque benefits. Cetylpyridinium chloride has been found to provide only limited clinical benefits compared to inactive control mouth rinse. Inadequate evidence is available to evaluate the clinical effectiveness of aloe vera gel. Chlorhexidine, essential oils and cetylpyridinium have been found to be safe. However, limited data are available on the effects of the mouth rinse on wear patterns of dental restorations. Studies reviewed reported no significant difference in salivary flow rate related to alcohol based mouth rinse. Research supports the effectiveness of antiseptic mouth rinses in reducing plaque and gingivitis as an adjunct to home care. Insufficient evidence is available to support the claim that oral antiseptics can reduce the risk of developing periodontitis or the

The purposes of this study were to assess the long-term efficacy of medialization laryngoplasty via injection of autologous fat in patients with unilateral laryngeal paralysis, and to discuss the results based on the volume of fat injected and the size of the initial glottic gap. This was a retrospective study with clinical reevaluation of 18 patients treated for unilateral laryngeal paralysis at Liège University Hospital between April 1, 2011, and December 1, 2014. The voice examination included subjective scales (GRBAS and the Voice Handicap Index), a report on acoustic and aerodynamic voice parameters, and laryngostroboscopic assessment of glottic closure and mucosal wave (T0: preoperative; T1: immediate postoperative; T2: >1 year). The median follow-up duration was 19 months. We observed a significant improvement in maximum phonation time; mean flow rate; jitter; the Voice Handicap Index; the G, R, B, and A subscales of the GRBAS-I; and glottic closure at T1. These parameters remained stable over time, without any significant difference except for shimmer and glottic closure between T1 and T2. Regardless of the volume of fat injected and the magnitude of the initial glottic gap, we did not see any significant difference from one assessment time to another. Medialization laryngoplasty by means of the injection of autologous fat is a safe, effective surgical technique for patients with unilateral laryngeal paralysis regardless of the size of the initial glottic gap. The results are maintained longer than 1 year, and no evidence of significant resorption of the fat was found in our study over a period of 12-58 months. The volume of fat injected does not seem to affect the functional results. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

To evaluate the safety and efficacy of the protective ptosis created by botulinum neurotoxin type-A in lagophthalmos cases due to peripheral facial paralysis. Protective ptosis was induced by 7.5 U botulinum neurotoxin type-A injection into levator muscles in 15 patients with peripheral facial paralysis and lagophthalmos. Its efficacy and safety were evaluated prospectively. Complete ophthalmological examinations were performed before and after injections; interpalpebral fissure, upper eyelid margin reflex distance, and levator muscle function were measured. In control visits, degree and duration of ptosis and side effects of the drug were evaluated. The mean age of the patients was 55 ± 14.28 years (22-78 years). Ptosis created by botulinum neurotoxin type-A injection was severe in 12 patients (80%), moderate in 2 patients (13.3%), and mild in 1 patient (6.7%). The effect of botulinum neurotoxin type-A began in 2.33 ± 1.44 days and peaked in 5.73 ± 2.63 days. No patient needed a second injection. The mean duration for ptosis was 10.53 ± 2.89 weeks. After development of ptosis, statistically significant improvement in corneal symptoms (p < 0.01) and decrease in daily artificial tear requirement (p < 0.01) were detected. Local or systemic side effects were not observed in any of the patients. In patients with peripheral facial paralysis and lagophthalmos, protective ptosis created by botulinum neurotoxin type-A injection into the levator muscle is a reliable and effective technique for the protection of the ocular surface and treatment of existing corneal complications. It represents an alternative treatment modality in cases requiring surgery.

To improve the manipulations of traditional heat-producing needling, and observe its therapeutic effect on peripheral facial paralysis. Acupuncture was adopted for all the 50 patients with peripheral facial paralysis. Acupoints such as Dicang (ST 4), Jiache (ST 6), Qianzheng (Extra), Fengchi(GB 20), Yifeng (TE 17) of the affected side, Hegu (LI 4) of the healthy side, Shousanli (LI 10), Zusanli (ST 36) and Taichong (LR 3) of both sides were adopted. And an adapted heat-producing needling was applied. With the left thumb of the doctor press at the point, the needle was rotated slowly with the right thumb moving forward and index finger moving backward to maintain the needling sensation. Then, heavier pressure was given with the left thumb, and a 9-time lifting and thrusting manipulation with small amplitude, low and even frequency by the right thumb and the index finger. Heavy pressure was maintained by the left thumb, and the needle was inserted by the right thumb and index finger to promote the needling sensation. Thus, the tip of the needle was always kept at the level where the needling sensation appeared. Therefore, a heat sensation can be felt by the patient under the needle or at the distal area. The treatment should be given once a day. And therapeutic effect was observed after 15 times continue treatment. All the 50 patients were cured without any sequela. Adapted heat-producing needling can promote the recovery of the function of facial muscle, and the effect of treatment of peripheral facial paralysis with the manipulation is confirmed.

Burning mouth syndrome (BMS) is a chronic pain condition. It has been described by the International Headache Society as "an intra-oral burning or dysesthetic sensation, recurring daily for more than 2 h/day for more than 3 months, without clinically evident causative lesions." BMS is frequently seen in women in the peri-menopausal and menopausal age group in an average female/male ratio of 7:1. The site most commonly affected is the anterior two-thirds of the tongue. The patient may also report taste alterations and oral dryness along with the burning. The etiopathogenesis is complex and is not well-comprehended. The more accepted theories point toward a neuropathic etiology, but the gustatory system has also been implicated in this condition. BMS is frequently mismanaged, partly because it is not well-known among healthcare providers. Diagnosis of BMS is made after other local and systemic causes of burning have been ruled out as then; the oral burning is the disease itself. The management of BMS still remains a challenge. Benzodiazepines have been used in clinical practice as the first-line medication in the pharmacological management of BMS. Nonpharmacological management includes cognitive behavioral therapy and complementary and alternative medicine (CAM). The aim of this review is to familiarize healthcare providers with the diagnosis, pathogenesis, and general characteristics of primary BMS while updating them with the current treatment options to better manage this group of patients.

Sporadic periodic paralysis (SPP), the second leading cause of hypokalemic periodic paralysis (HPP) in Asia, has a presentation similar to that of familial periodic paralysis (FPP) and is caused by gene mutations in the calcium (Ca(2+)) (CACNA1S) and sodium (Na(+)) (SCN4A) channels of skeletal muscle. The authors determined whether SPP shares similar genotype and phenotype with FPP. Sixty SPP patients who did not have a family history of paralysis, abnormal thyroid function tests and other identifiable causes of HPP, and 8 FPP patients were enrolled. Genomic DNA was isolated from blood leukocytes of all SPP and FPP patients. Genetic analysis of whole S4 segment in CACNA1S and SCN4A was performed. Phenotypic analysis included clinical presentations, laboratory data and precipitating events. All FPP patients had mutations in either CACNA1S or SCN4A, but only 4 SPP patients had de novo mutations in CACNA1S (R1239H) and SCN4A (R669×2, R1135H). SPP patients with de novo mutations manifested a phenotype indistinguishable from that of FPP patients except a later age of onset. SPP patients without mutations also had a later age of onset, significantly fewer attacks of paralysis than FPP patients, and unidentifiable precipitating factors. A minority of SPP patients had de novo CACNA1S or SCN4A mutations and may have a variant of FPP. The majority of SPP patients, those without mutations in CACNA1S and SCN4A, represent a unique subgroup of HPP patients, and this form of SPP usually manifests at a later age, is associated with fewer attacks and lacks apparent triggering factors.

As yet, no cure exists for upper-limb paralysis resulting from the damage to motor pathways after spinal cord injury or stroke. Recently, neural activity from the motor cortex of paralyzed individuals has been used to control the movements of a robot arm but restoring function to patients' actual limbs remains a considerable challenge. Previously we have shown that electrical stimulation of the cervical spinal cord in anesthetized monkeys can elicit functional upper-limb movements like reaching and grasping. Here we show that stimulation can be controlled using cortical activity in awake animals to bypass disruption of the corticospinal system, restoring their ability to perform a simple upper-limb task. Monkeys were trained to grasp and pull a spring-loaded handle. After temporary paralysis of the hand was induced by reversible inactivation of primary motor cortex using muscimol, grasp-related single-unit activity from the ventral premotor cortex was converted into stimulation patterns delivered in real-time to the cervical spinal gray matter. During periods of closed-loop stimulation, task-modulated electromyogram, movement amplitude, and task success rate were improved relative to interleaved control periods without stimulation. In some sessions, single motor unit activity from weakly active muscles was also used successfully to control stimulation. These results are the first use of a neural prosthesis to improve the hand function of primates after motor cortex disruption, and demonstrate the potential for closed-loop cortical control of spinal cord stimulation to reanimate paralyzed limbs.

Although it is known that Israeli acute paralysis virus (IAPV) can cause bee mortality, the symptoms of paralysis and the distribution of the virus in different body tissues and their potential to respond with an increase of the siRNA antiviral immune system have not been studied. In this project we worked with Bombus terrestris, which is one of the most numerous bumblebee species in Europe and an important pollinator for wild flowers and many crops in agriculture. Besides the classic symptoms of paralysis and trembling prior to death, we report a new IAPV-related symptom, crippled/immobilized forelegs. Reverse-transcriptase quantitative PCR showed that IAPV accumulates in different body tissues (midgut, fat body, brain and ovary). The highest levels of IAPV were observed in the fat body. With fluorescence in situ hybridization (FISH) we detected IAPV in the Kenyon cells of mushroom bodies and neuropils from both antennal and optic lobes of the brain in IAPV-infected workers. Finally, we observed an induction of Dicer-2, a core gene of the RNAi antiviral immune response, in the IAPV-infected tissues of B. terrestris workers. According to our results, tissue tropism and the induction strength of Dicer-2 could not be correlated with virus-related paralysis symptoms.

Damage to the facial nerve due to trauma from traffic accidents is the second most common cause of paralysis of the facial nerve. The treatments include both pharmacological and non-pharmacological therapy. Acupuncture is a method of treatment that applies evidence-based medical principles and uses anatomy, physiology, and pathology to place needles atcertain acupuncture points. This paper describes a 26-year-old female patient with right-side facial palsy following a traffic accident who had animproved Brackmann’s score after 12 sessions of acupuncture treatment. The acupuncture points were chosen based on Liu Yan’sbrain-clearing needling technique. Acupuncture can shorten healing time and improve the effect of treatment for facial-nerve paralysis.

The epidermoid cysts are frequent during childhood, however mouth floor location are very unusual, because of their more difficult diagnosis and therapeutic approach. We present a 5 years old male, symptoms free until a week before, when his parents noticed a well defined mass in the mouth floor. A physical examination leaded to the diagnosis of possible epidermoid cyst. The tumor was excised through an introral approach. A review of different diagnostic means and surgical management are undertaken.

Hydra, a simple freshwater animal famous for its regenerative capabilities, must tear a hole through its epithelial tissue each time it opens its mouth. The feeding response of Hydra has been well-characterized physiologically and is regarded as a classical model system for environmental chemical biology. However, due to a lack of in vivo labeling and imaging tools, the biomechanics of mouth opening have remained completely unexplored. We take advantage of the availability of transgenic Hydra lines to perform the first dynamical analysis, to our knowledge, of Hydra mouth opening and test existing hypotheses regarding the underlying cellular mechanisms. Through cell position and shape tracking, we show that mouth opening is accompanied by changes in cell shape, but not cellular rearrangements as previously suggested. Treatment with a muscle relaxant impairs mouth opening, supporting the hypothesis that mouth opening is an active process driven by radial contractile processes (myonemes) in the ectoderm. Furthermore, we find that all events exhibit the same relative rate of opening. Because one individual can open consecutively to different amounts, this suggests that the degree of mouth opening is controlled through neuronal signaling. Finally, from the opening dynamics and independent measurements of the elastic properties of the tissues, we estimate the forces exerted by the myonemes to be on the order of a few nanoNewtons. Our study provides the first dynamical framework, to our knowledge, for understanding the remarkable plasticity of the Hydra mouth and illustrates that Hydra is a powerful system for quantitative biomechanical studies of cell and tissue behaviors in vivo.

The aim of this study is to evaluate the efficacy and the safety of Sanyak pharmacopuncture therapy for the treatment of peripheral facial paralysis patients. This study was a retrospective investigation of a total of 70 patients who were inpatients of the Oriental Hospital of Daejeon University between January 1, 2011, and May 31, 2012, and who were diagnosed as having peripheral facial paralysis by physical examination, the patients received three different interventions. Eleven (11) patients were treated with acupuncture and alcohol Dioscorea rhizoma pharmacopuncture (ADG), 25 patients with acupuncture and distillation Dioscorea rhizoma pharmacopuncture (DDG), and 34 patients with acupuncture and non-Dioscorea rhizoma pharmacopuncture (NDG). The resulting data were analyzed. The changed H-B grades indicated significant improvements in all three groups, and the ADG and the DDG groups showed significant results after two weeks of treatment when compared to the NDG group. The changed y-Scores indicated significant improvements in all three groups, and the ADG group showed significant results after 10 and 15 days of treatment when compared to the NDG group. Dioscorea rhizoma pharmacopuncture may be safe for the human body because in most cases, the only abnormal finding was the pain could by the application of pharmacopuncture. The results of this study suggest that Oriental medical treatment with dioscoreae Rhizoma (Sanyak) pharmacopuncture complex therapy may be effective and safe in patient with peripheral facial paralysis.

Burning mouth syndrome (BMS) is characterized by the presence of burning sensation of the oral mucosa in the absence of clinically apparent mucosal alterations. It occurs more commonly in middle-aged and elderly women and often affects the tongue tip and lateral borders, lips, and hard and soft palate. In addition to a burning sensation, the patients with BMS may also complain unremitting oral mucosal pain, dysgeusia, and xerostomia. BMS can be classified into two clinical forms: primary and secondary BMS. The primary BMS is essential or idiopathic, in which the organic local/systemic causes cannot be identified and a neuropathological cause is likely. The diagnosis of primary BMS depends mainly on exclusion of etiological factors. The secondary BMS is caused by local, systemic, and/or psychological factors; thus, its diagnosis depends on identification of the exact causative factor. When local, systemic or psychological factors are present, treatment or elimination of these factors usually results in a significant clinical improvement of BMS symptoms. Vitamin, zinc, or hormone replacement therapy has been found to be effective for reducing the oral burning or pain symptom in some BMS patients with deficiency of the corresponding factor. If patients still have the symptoms after the removal of potential causes, drug therapy should be instituted. Previous randomized controlled clinical trials found that drug therapy with capsaicin, alpha-lipoic acid, clonazepam, and antidepressants may provide relief of oral burning or pain symptom. In addition, psychotherapy and behavioral feedback may also help eliminate the BMS symptoms.

meta analysis.Acupuncture studies did not provide useful data as all were short and at high risk of bias. None of the studies included adverse events as an outcome. There is no high quality evidence to support significant benefit or harm from any physical therapy for idiopathic facial paralysis. There is low quality evidence that tailored facial exercises can help to improve facial function, mainly for people with moderate paralysis and chronic cases. There is low quality evidence that facial exercise reduces sequelae in acute cases. The suggested effects of tailored facial exercises need to be confirmed with good quality randomised controlled trials.

Botulinum toxin A has been described as an effective adjunct treatment for achieving symmetry in adults with facial paralysis. Few investigators have described the use of botulinum toxin A in pediatric patients with facial paralysis. To present our preliminary experience with botulinum toxin A in pediatric patients presenting with asymmetry of the lower lip. We performed a retrospective medical record review of all pediatric patients (age range, 4-17 years; mean [SD] age, 11.2 [4.7] years) with facial paralysis who were treated with botulinum toxin A injections from January 1, 2004, through December 31, 2012. Patients presented for treatment at The Hospital for Sick Children, Toronto, Ontario, Canada, or the Massachusetts Eye and Ear Infirmary, Boston. Using facial analysis software, we measured lower lip asymmetry in the patients' photographs before and after treatment, at rest, and in a dynamic state. We performed analysis of variance to assess for improvement in symmetry. We identified 18 patients with the following 3 primary indications for treatment: focal lip asymmetry (n = 11), extensive hemifacial asymmetry (n = 5), and focal synkinesis (n = 2). We found no complications related to botulinum toxin A treatment. The mean (SD) dynamic deviation before the injection was 3.5 (1.7) mm, whereas the mean dynamic deviation after the injection was 1.5 (0.8) mm. The mean (SD) deviation correction was evaluated at 61% (6%) and was statistically significant (P = .04). Botulinum toxin A injection is a safe procedure for improving localized asymmetry in pediatric patients with facial paralysis. Preliminary results indicate that botulinum toxin A may be an effective treatment for lower lip asymmetry in children and adolescents. 4.

A peptide-based vaccine for foot-and-mouth disease (FMD) was designed. The peptide immunogen had a G-H loop domain optimised for immunogenicity and broad-spectrum antigenicity to different lineages of serotype-O FMD viruses (FMDVs). Polyinosinic and poly-cytidylic acid [poly (I:C)] was used as the adjuvant to overcome the low humoral antibody levels often observed in association with peptide-based vaccines. The multi-epitope peptide alone induced the secretion of a certain level of neutralising antibodies in mice. In contrast, co-administration of the multi-epitope peptide with poly (I:C) induced the secretion of a significantly higher level of neutralising antibodies (P<0.005). Indeed, the resultant level was slightly higher even than that induced by the inactivated vaccine (P>0.05). These initial results indicate that poly (I:C) is highly effective as an adjuvant for use with the FMDV multi-epitope peptide vaccine. This combination could yield a promising vaccine for the prevention and control of FMD. Further study is needed to evaluate the efficiency of this combination on animals susceptible naturally to FMDV.

The goal of this pilot study was to test vocal fold medialization using autologous tragal cartilage and perichondrium by direct approach for treating high vagal paralysis. Five patients with the skull base tumors with involvement of the vagus nerve underwent concurrent vocal fold medialization with surgical excision. The patients were evaluated preoperatively, and at 14, 60 days, and 6 months later. Complete medialization with horizontal and vertical realignment was achieved. Improvement of voice and breathiness was correlated with the increase of closed quotient; the contact area of the vocal fold mucosa has increased. This advancement reduces breathiness and induced an improvement in subglottic pressure with aerodynamic parameters improvement, which led to stabilization of the vocal fold oscillation and a better voice quality recovery. This method can be considered a safe, quick, and efficient phonosurgical procedure combined with a skull-base surgical procedure.

Peripheral nerve lesions are one of the most frequent causes of chronic incapacity. Upper or lower limb palsies due to brachial or lumbar plexus injuries, facial paralysis and nerve lesions caused by systemic diseases are one of the major goals of plastic and reconstructive surgery. However, the poor results obtained in repaired peripheral nerves during the Second World War lead to a pessimist vision of peripheral nerve repair. Nevertheless, a well understanding of microsurgical principles in reconstruction and molecular biology of nerve regeneration have improved the clinical results. Thus, although the results obtained are quite far from perfect, these procedures give to patients a hope in the recuperation of their lesions and then on function. Technical aspects in nerve repair are well established; the next step is to manipulate the biology. In this article we will comment the biological processes which appear in peripheral nerve regeneration, we will establish the main concepts on peripheral nerve repair applied in facial paralysis cases and, finally, we will proportionate some ideas about how clinical practice could be affected by manipulation of the peripheral nerve biology.

We describe the presenting features and long-term outcome of an unusual cluster of pediatric acute flaccid paralysis cases that occurred in Canada during the 2014 enterovirus D68 outbreak. Children (n = 25; median age 7.8 years) presenting to Canadian centers between July 1 and October 31, 2014, and who met diagnostic criteria for acute flaccid paralysis were evaluated retrospectively. The predominant presenting features included prodromal respiratory illness (n = 22), cerebrospinal fluid lymphocytic pleocytosis (n = 18), pain in neck/back (n = 14) and extremities (n = 10), bowel/bladder dysfunction (n = 9), focal central gray matter lesions found in all regions of the spinal cord within the cohort (n = 16), brain stem lesions (n = 8), and bulbar symptoms (n = 5). Enterovirus D68 was detectable in nasopharyngeal specimens (n = 7) but not in cerebrospinal fluid. Acute therapies (corticosteroids, intravenous immunoglobulins, plasmapheresis) were well tolerated with few side effects. Fourteen of 16 patients who were followed beyond 12 months post onset had neurologic deficits but showed ongoing clinical improvement and motor recovery.

We report a case of conversion paralysis after cervical spine arthroplasty performed in a 45-year-old woman to treat cervico-brachial neuralgia due to a left-sided C6-C7 disc herniation. Upon awakening from the anaesthesia, she had left hemiplegia sparing the face, with normal sensory function. Magnetic resonance imaging (MRI) of the brain ruled out a stroke. MRI of the spinal cord showed artefacts from the cobalt-chrome prosthesis that precluded confident elimination of mechanical spinal cord compression. Surgery performed on the same day to substitute a cage for the prosthesis ruled out spinal cord compression, while eliminating the source of MRI artefacts. Findings were normal from follow-up MRI scans 1 and 15days later, as well as from neurophysiological testing (electromyogram and motor evoked potentials). The deficit resolved fully within the next 4days. A psychological assessment revealed emotional distress related to an ongoing divorce. The most likely diagnosis was conversion paralysis. Surgeons should be aware that conversion disorder might develop after a procedure on the spine, although the risk of litigation requires re-operation. Familiarity with specific MRI sequences that minimise artefacts can be valuable. A preoperative psychological assessment might improve the detection of patients at high risk for conversion disorder.

Objective. Autologous fat injection laryngoplasty is ineffective for some patients with iatrogenic vocal fold paralysis, and additional laryngeal framework surgery is often required. An acoustically measurable outcome predictor for lipoinjection laryngoplasty would assist phonosurgeons in formulating treatment strategies. Methods. Seventeen thyroid surgery patients with unilateral vocal fold paralysis participated in this study. All subjects underwent lipoinjection laryngoplasty to treat postsurgery vocal hoarseness. After treatment, patients were assigned to success and failure groups on the basis of voice improvement. Linear prediction analysis was used to construct a new voice quality indicator, the number of irregular peaks (NIrrP). It compared with the measures used in the Multi-Dimensional Voice Program (MDVP), such as jitter (frequency perturbation) and shimmer (perturbation of amplitude). Results. By comparing the [i] vowel produced by patients before the lipoinjection laryngoplasty (AUC = 0.98, 95% CI = 0.78–0.99), NIrrP was shown to be a more accurate predictor of long-term surgical outcomes than jitter (AUC = 0.73, 95% CI = 0.47–0.91) and shimmer (AUC = 0.63, 95% CI = 0.37–0.85), as identified by the receiver operating characteristic curve. Conclusions. NIrrP measured using the LP model could be a more accurate outcome predictor than the parameters used in the MDVP. PMID:27738634
Concentrating a wide range of spinal cord injury (SCI) research laboratories in a single location to accelerate progress and draw attention to the promise of SCI research has made The Miami Project to Cure Paralysis one of the most publicly recognized and often controversial research groups in the neurosciences. A "Center of Excellence" at the University of Miami School of Medicine, the Miami Project also serves as a model for SCI research programs being developed nationally and internationally. Founded in 1985, the Miami Project set out on an unprecedented path-to develop a research center dedicated to improving treatments for SCI by bridging basic and clinical science. In doing so, neurosurgeon Barth Green, M.D., enlisted not only a multidisciplinary team of scientists but also a devoted following of financial donors and volunteer research subjects, and support from the University of Miami and Florida legislature. Highly visible spokespersons, including cofounder ex-Miami Dolphin Nick Buoniconti and his son Marc, brought the issue of SCI paralysis and the promise of research before the public, the media, and sports communities. As progress in the neurosciences has raced ahead, public attention to medical research, and SCI research in particular, has grown exponentially. This review will assess the Miami Project as a model for disease-based research that unites academic, philanthropic, and patient communities in a common cause.

Advances in high-performance computing are enabling a new generation of software tools that employ computational modeling for surgical planning. Surgical management of laryngeal paralysis is one area where such computational tools could have a significant impact. The current paper describes a comprehensive effort to develop a software tool for planning medialization laryngoplasty where a prosthetic implant is inserted into the larynx in order to medialize the paralyzed vocal fold (VF). While this is one of the most common procedures used to restore voice in patients with VF paralysis, it has a relatively high revision rate, and the tool being developed is expected to improve surgical outcomes. This software tool models the biomechanics of airflow-induced vibration in the human larynx and incorporates sophisticated approaches for modeling the turbulent laryngeal flow, the complex dynamics of the VFs, as well as the production of voiced sound. The current paper describes the key elements of the modeling approach, presents computational results that demonstrate the utility of the approach and also describes some of the limitations and challenges.

The purpose of this case report is to describe a therapeutic intervention for peroneal nerve paralysis involving the sciatic nerve. A 24-year-old man presented with peroneal nerve paralysis with decreased sensation, severe pain in the popliteal fossa, and steppage gait, which occurred 3 days prior to the consultation. Magnetic resonance imaging and electromyography confirmed lumbar disk herniation with sciatic common peroneal nerve entrapment in the popliteal fossa. A combined treatment protocol of spinal and fibular head manipulation and neurodynamic mobilization including soft tissue work of the psoas and hamstring muscles was performed. Outcome measures were assessed at pretreatment, 1 week posttreatment, and 3-month follow-up and included numeric pain rating scale, range of motion, pressure pain threshold, and manual muscle testing. Treatment interventions were applied for 3 sessions over a period of 1 week. Results showed reduction of the patient's subjective pain and considerable improvement in range of motion, strength, and sensation in his left foot, which was restored to full function. A combined program of spinal and fibular head manipulation and neurodynamic mobilization reduced pain, increased range of motion and strength, and restored full function to the left leg in this patient who had severe functional impairment related to a compressed left common peroneal nerve.

Nonsense-mediated mRNA decay (NMD) is an RNA surveillance mechanism that requires upframeshift protein 1 (UPF1). This study demonstrates that human UPF1 exerts protective effects in a rat paralysis model based on the amyotrophic lateral sclerosis (ALS)-associated protein, TDP-43 (transactive response DNA-binding protein 43 kDa). An adeno-associated virus vector (AAV9) was used to express TDP-43 throughout the spinal cord of rats, inducing reproducible limb paralysis, to recapitulate the paralysis in ALS. We selected UPF1 for therapeutic testing based on a genetic screen in yeast. The expression of human TDP-43 or human UPF1 in the spinal cord was titrated to less than twofold over the respective endogenous level. AAV9 human mycUPF1 clearly improved overall motor scores in rats also expressing TDP-43. The gene therapy effect of mycUPF1 was specific and reproducible compared with groups receiving either empty vector or green fluorescent protein vector controls. The gene therapy maintained forelimb motor function in rats that would otherwise become quadriplegic. This work helps validate UPF1 as a novel therapeutic for ALS and other TDP-43-related diseases and may implicate UPF1 and NMD involvement in the underlying disease mechanisms.

Acute unilateral facial paralysis, such as occurs in Bell palsy and Hunt syndrome, is mostly a benign neurologic morbidity that resolves within a few months. However, incomplete or misdirected return of the affected nerve results in unfavorable cosmetic sequelae in some patients. Although functional problems such as lagophthalmos are rare, facial asymmetry on smiling resulting from a lack of mimetic muscle strength in the cheek is often psychologically annoying to patients. To obtain a more natural smile, the authors transfer latissimus dorsi muscle to assist in cheek movement. A small, thinned muscle (mini-latissimus dorsi) is sufficient for transplant in this situation. In this study, 96 patients with incomplete facial paralysis who underwent mini-latissimus dorsi transfer were examined. In this series, along with evaluation using the grading scale used in previous reports, preoperative and postoperative videos of 30 patients were analyzed for quantitative assessment using newly developed computer software. Temporary deterioration of paralysis was recognized in three cases but did not last more than a few months. Signs of transferred muscle contraction were recorded after 4 to 12 months among 91 patients. No apparent clinical signs of contraction were recognized in one patient, and four patients could not be followed postoperatively. The synchronized ratio of vertical movement and the symmetrical ratio of horizontal movement both in the cheek and in the lower lip between healthy and paralyzed sides among 30 patients were statistically improved. Statistical analysis using newly developed computer software revealed that a more symmetrical smile can be achieved by muscle transfer among patients with incomplete facial paralysis. Mini-latissimus dorsi transfer can avoid postoperative muscle bulkiness of the cheek and can achieve more natural cheek movement.

Facial paralysis is a common craniofacial deformity that is responsible for significant psychological and functional impairment. Free muscle transfer in 2 stages and latissimus dorsi transfer in one stage may be the most effective surgical procedure for achieving a symmetrical spontaneous smile for a patient with complete facial paralysis. However, these 2 procedures are unsuitable for many incomplete patients. The authors introduce a less invasive procedure, termed mini-temporalis transposition that is able to achieve a symmetrical spontaneous smile in incomplete patients. Through a zigzag incision into the temporal region, the middle third of the temporalis is transferred and elongated with the palmaris longus tendon or combined with the deep temporal fascia. The strips are anchored to key points at the modiolus and the middle of the ipsilateral orbicularis oris muscle through a small intraoral incision and subcutaneous tunnel. The key points are marked during preoperative smile analysis. This procedure was applied to 15 patients with long-standing incomplete facial paralysis. All patients obtained improvements in smile symmetry after the operation, and patients' satisfaction was high. In addition, no damage to residual facial nerve functions or development of procedure-induced complications (such as a facial contour defect, lip eversion or puckering, or skin tethering) was observed in any of the patients. Nevertheless, slight temporal hollowing was observed in 4 patients, and mild bulkiness over the zygomatic arch was a common observation. In summary, the mini-temporalis transfer technique is a safe and effective method of smile restoration for long-standing incomplete facial paralysis.

Two pathogenetically distinct disease manifestations are distinguished in a murine model of primary rabies virus infection with the Evelyn-Rokitnicky-Abelseth strain, rabies virus neuritic paralysis (RVNP) and fatal encephalopathogenic rabies. RVNP develops with high incidence in immunocompetent mice after intraplantar infection as a flaccid paralysis restricted to the infected limb. The histopathologic correlate of this monoplegia is a degeneration of the myelinated motor neurons of the peripheral nerve involved. While, in this model, fatal encephalopathogenic rabies develops only after depletion of the CD4 subset of T lymphocytes and without contribution of the CD8 subset, RVNP is identified as an immunopathological process in which both the CD4 and CD8 subsets of T lymphocytes are critically implicated.

Sleep paralysis occurs in normal persons. This phenomenon had been studied psychoanalytically or in terms of the deviation of the victims' personality. This present study aimed to assess the personalities of such persons by using the MMPI and the Maudsley Personality Inventory. The subjects showed a slightly higher mean T score on the MMPI Paranoia Scale than those who did not have this experience. Although this personality difference might be related to the occurrence of the phenomenon, this difference is probably too small to take a major role. It is unlikely that the subjects developed paranoic behavior through their experiences of sleep paralysis, since their experiences were very few. Some of the subjects might have only overestimated their behavior and experiences concerning delusions and hallucinations, with the result that their Paranoia scores were higher and perhaps their kanashibari experiences exaggerated.

In Japan, a set of experiences called kanashibari is considered identical with isolated sleep paralysis. We investigated this phenomenon by means of a questionnaire administered to 635 college students (390 men and 245 women). Of all subjects, about 40% had experienced at least one episode of kanashibari [subjects of K(+)]. Therefore, isolated sleep paralysis is apparently a more common phenomenon than is usually appreciated. About half of the subjects of K(+) reported that they had been under "physical or psychological stress" or in a "disturbed sleep and wakefulness cycle" immediately before the episode. Many subjects of K(+) experienced the first episode in adolescence. In the distribution of age of first attack, the peak occurred at an earlier age in women subjects than in men subjects. These findings suggest that two factors influence the occurrence of the phenomenon. One is exogenous physical or psychological load and the other is endogenous biological development.

Tick-borne diseases are seen all over the world and their importance rises increasingly. It is noticeably important that disease and death rates due to tick-bites in our country in different areas increased in 2008. In Turkey, the numbers of diseases which are transmitted by ticks are considerably large and all of them are not detected. Reports of isolated facial paralysis cases due to tick infestation in the ear are infrequent in literature. The development of isolated facial paralysis due to ticks can be explained by several theories. This article reports a case report of a 3 year- old girl who was bought to our clinic with severe left ear pain and paresthesia on the left half of her face. She couldn't close her left eye and she lisped. The tick was removed from her external auditory canal surgically.

Hypokalemic Periodic Paralysis (HPP) may occur as a rare complication of Sjogren Syndrome (SS) and Renal Tubular Acidosis (RTA). A 64-year male patient came with HPP, and was later diagnosed with distal RTA. The patient, who had no xerostomia and xerophthalmia, was diagnosed with primary SS from serologic and histologic findings of minor salivary gland biopsy. The patient recovered after potassium replacement therapy. Renal biopsy was also performed and revealed evidence of tubulointerstitial nephritis. Corticosteroids were administered and there was no recurrence of HPP during a 4-year follow-up period. The case highlights the significance of acute hypokalemia management in emergency department as it can unmask SS even if the SS is not associated with sicca symptoms. Hypokalemic paralysis associated with normal anion gap metabolic acidosis should prompt toward the diagnosis of SS.
Periodic paralysis is a muscle disorder that belongs to the family of diseases called channelopathies, manifested by episodes of painless muscle weakness. Periodic paralysis is classified as hypokalemic when episodes occur in association with low potassium levels. Most cases are hereditary. Acquired cases have been described in association with hyperthyroidism. Diagnosis is made on clinical and biochemical grounds. Patients may be markedly hypokalemic during the episode and respond well to potassium supplementation. Episodes can be prevented by achieving a euthyroid state. This report describes a young gentleman presenting with thyrotoxic hypokalemic paraparesis. The condition needs to be considered in the differential diagnosis of neuromuscular weakness in the context of hypokalemia by the treating physicians.

Phrenic nerve palsy has previously been associated with brachial plexus root avulsion; severe unilateral phrenic nerve injury is not uncommonly associated with brachial plexus injury. Brachial plexus injuries can be traumatic (gunshot wounds, lacerations, stretch/contusion and avulsion injuries) or non-traumatic in aetiology (supraclavicular brachial plexus nerve block, subclavian vein catheterisation, cardiac surgeries, or obstetric complications such as birth palsy). Despite the known association, the incidence and morbidity of a phrenic nerve injury and hemidiaphragmatic paralysis associated with traumatic brachial plexus stretch injuries remains ill-defined. The incidence of an associated phrenic nerve injury with brachial plexus trauma ranges from 10% to 20%; however, because unilateral diaphragmatic paralysis often presents without symptoms at rest, a high number of phrenic nerve injuries are likely to be overlooked in the setting of brachial plexus injury. A case report is presented of a unilateral phrenic nerve injury associated with brachial plexus stretch injury presenting with a recalcitrant left lower lobe pneumonia.

Diphtheritic polyneuropathy is a vaccine-preventable illness caused by exotoxin-producing strains of Corynebacterium diphtheriae. We present a retrospective convenience case series of 15 children (6 girls) <15 years of age (mean age 5.2 years, case-fatality rate 53%, and 1 additional case-patient who was ventilator dependent at the time of last follow-up; median follow-up period 60 days) with signs and symptoms suggestive of diphtheritic polyneuropathy. All cases were identified through national acute flaccid paralysis surveillance, which was designed to detect poliomyelitis in India during 2002–2008. We also report data on detection of diphtheritic polyneuropathy compared with other causes of acute flaccid paralysis identified by this surveillance system. PMID:23965520

In the last 10 years, wound botulism has increasingly been reported and nearly all of these new cases have occurred in injecting-drug abusers. After absorption into the bloodstream, botulinum toxin binds irreversibly to the presynaptic nerve endings, where it inhibits the release of acetylcholine. Diplopia, blurred vision, dysarthria, dysphagia, respiratory failure and paresis of the limbs are common symptoms of this intoxication. Surprisingly and despite the well-known blocking action of the botulinum toxin on the autonomic nerve system, little attention has been paid to changes in the lower urinary tract following acute botulinum toxin poisoning. Here we report a case of bladder paralysis following wound botulism. Early diagnosis and adequate management of bladder paralysis following botulism is mandatory to avoid urologic complications. Accordingly, the prognosis is usually favorable and the bladder recovery complete.

The method of surgical treatment of bilateral vocal cord paralysis with the use of laser CO2 is presented. This technique was used in 20 patients. The vaporization and extirpation of arytenoid cartilage was performed together with resection of 1/3 of the posterior vocal cord which was removed. Analyzing other methods of treatment of bilateral vocal cord paralysis it was emphasized that with the use of the presented method good results in preserving breathing and phonation of the operated part was archived. It was also emphasized that the fast process of healing and lack of granulation in the operated field allows for the quick recovering patient. This method allows to obtain good wide larynx lumen without the necessity to perform tracheotomy--in 17 out of 20 our patients we could perform laser arytenoidectomy without tracheotomy.

A 7-month-old Quarter Horse filly was admitted for surgical repair of a right olecranon fracture. Anesthesia was achieved with xylazine hydrochloride, guaifenesin, ketamine hydrochloride, and halothane. Two and a half hours after induction of anesthesia, myotonia, muscle fasciculations, and sweating, concurrent with high serum potassium concentration and associated electrocardiographic changes consistent with hyperkalemic periodic paralysis, were observed. Treatment included intermittent positive-pressure ventilation, changing intravenous administration of fluids from lactated Ringer's solution to 0.9% NaCl solution, and administration of calcium gluconate, glycopyrrolate, dopamine, and sodium bicarbonate. Clinical signs resolved with the return of serum potassium concentrations to the reference range. The horse was confirmed to be heterozygous for hyperkalemic periodic paralysis by DNA testing.
Vocal cord paralysis is a relatively common entity, usually resulting from a pathologic process of the vagus nerve or its recurrent larynegeal branch. It is rarely caused by intralargngeal lesions. Four teen patients with recurrent laryngeal nerve paralysis (RLNP) were evaluated by laryngography, computed tomography (CT), or both. In the evaluation of the paramedian cord, CT was limited in its ability to differentiate between tumor or RLNP as the cause of the fixed cord, but it yielded more information than laryngography on the structural abnormalities of the larynx and pre-epiglottic and paralaryngeal spaces. Laryngography revealed distinct features of RLNP and is the procedure of choice for evaluation of functional abnormalities of the larynx until further experience with faster CT scanners and dynamic scanning of the larynx is gained.

It is generally believed that peripheral facial paralysis is mainly caused by vacancy of collaterals, invasion of pathogenic wind-cold and wind-heat to facial tendons and meridians, which lead to stagnation of qi and blood, loss of nourishment of tendons, and flaccidity of muscle. The authors belive that the main etiology and pathogenesis of facial paralysis could be deficiency of yin and blood, emptiness of Yangming and Shaoyang collaterals, lack of liver blood which all lead to loss of nourishment, which is combined with exogenous pathogenic wind-cold, that causes stagnation of meridian qi, loss of nourishment of tendons, and flaccidity of muscle. Thus, yin and yang of the Governor Vessel and the Conception Vessel should be regulated for treatment, Siguan (LR 3 and LI 4) should be always used in points selection, and moxibustion should be applied carefully.

Acute hypokalemic periodic paralysis may be induced by betamethasone injections during pregnancy. A healthy 23-year-old gravid woman at 32 weeks of gestation with preterm premature rupture of membranes received two doses of 12-mg intramuscular betamethasone 24 hours apart to accelerate fetal lung maturation. She developed significant proximal muscle weakness within 16 hours after the initial dose. Her serum potassium was 1.6 mEq/L. Oral and parenteral potassium replacement restored her neuromuscular function over several days. She delivered by repeat cesarean at 34 weeks of gestation without complications for her or the neonate. Hypokalemic periodic paralysis, a rare cause of weakness, may be induced by betamethasone injections during pregnancy and is reversible with low-risk interventions.

Facial nerve paralysis (FNP) is a very rare complication of otitis media with effusion (OME). There are few patients with OME and FNP in the literature. A 5-year-old girl was admitted to our department with right facial weakness. Right FNP and right OME were diagnosed on the examination. After medical treatment and ventilation tube insertion, FNP completely resolved. The symptoms, signs, and management of this patient are presented.

Leptomeningeal carcinomatosis is rare, and its precise incidence is unknown. It is associated with a wide spectrum of solid and hematological malignancies. To complicate its diagnosis, the clinical presentation of leptomeningeal carcinomatosis can be variable. We report a case of a 38-year-old male with bilateral facial nerve paralysis as first presentation of lung adenocarcinoma. To our knowledge, this is the only case describing bilateral facial nerve palsy as the first and only manifestation of lung adenocarcinoma. PMID:28101027
Thyrotoxic periodic paralysis (TPP) is a rare, but serious condition characterized by acute paralytic attacks and hypokalemia in association with thyrotoxicosis. Although carbohydrate rich meals, strenuous exercise, alcohol, emotional stress are known precipitants of TPP, steroid treatment has rarely been reported to induce TPP. We report a case in which a patient with previously untreated Grave's disease developed TPP following administration of Intravenous hydrocortisone for control of severe anaphylaxis, which to best of our knowledge is very rare.

Our aims in this paper are threefold. First, to understand how the mouth reveals the kinds of human beings that are de/valued in specific national locations and in global discourses with special attention on disability. Second, to subject the mouth to analysis from critical disability studies, specifically, an approach we describe as dis/ability studies. Third, to ask how the mouth might work as a site of resistance for disabled people. The paper begins by providing an introduction to critical disability studies, a perspective that foregrounds disability as the primary focus for thinking through the ways in which the body and society are shaped together. We move in this literature review towards a dis/ability studies approach that recognises the simultaneous processes of disablism (the exclusion of people with impairments) and ableism (the system by which standards of human autonomy and capability are made as key indicators of human worth). We then analyse the mouth in relation to pathologisation, human enhancement and resistance. We conclude with some final thoughts on the offerings of a dis/ability studies approach to those of interested with the intersections of the mouth and society.

Patients with physical disabilities precluding functional use of their limbs can benefit enormously from the expertise of the dental profession. The dental clinician is able to not only meet the routine oral health needs of these patients, but possesses the unique skills and knowledge to provide specialised oral prosthetic appliances which can facilitate a range of independent activities. Mouth sticks, as they are commonly known, are dental prostheses that are held intra-orally by the patient and manipulated to perform numerous actions such as drawing, writing and painting. They have been well documented within dental and occupational therapy literature and reports of their fabrication date back over 150 years, albeit in a very rudimentary form. The enduring value of mouth sticks to the physically disabled population is that they can provide a degree of self-reliance which would otherwise not be afforded to them. This article discusses the evolution of mouth sticks, principles of mouth stick design, patient selection criteria and treatment planning considerations. We present two recent clinical cases where mouth sticks have been indicated and have been indispensable to the user, detailing the clinical and laboratory stages involved.

The number of people being diagnosed with mouth cancer (oral cancer) is increasing, with notable rises in incidence in younger people and in females. There are certain lifestyle habits that can increase the risk of mouth cancer, such as smoking or chewing tobacco, drinking alcohol above recommended levels (especially in those who also smoke), and chewing betel nut (areca nut). Infection with human papillomavirus (HPV) increases the risk of some types of mouth cancer, and too much sun exposure may also raise the risk of lip cancers. The signs and symptoms of mouth cancer can often be seen or felt, and any red or white patch, ulcer or lump can be an early sign if it lasts for three or more weeks. If people notice any of these changes, they should seek help from their dentist, doctor, or another healthcare professional without delay, because if mouth cancer is diagnosed at an early stage, when the lesions are small, treatment is generally less complicated and more effective.

It is known that the oral cavity is a production site for mouth-exhaled NH3. However, the mechanism of NH3 production in the oral cavity has been unclear. Since bacterial urease in the oral cavity has been found to produce ammonia from oral fluid urea, we hypothesize that oral fluid urea is the origin of mouth-exhaled NH3. Our results show that under certain conditions a strong correlation exists between oral fluid urea and oral fluid ammonia (NH4(+)+NH3) (rs = 0.77, p < 0.001). We also observe a strong correlation between oral fluid NH3 and mouth-exhaled NH3 (rs = 0.81, p < 0.001). We conclude that three main factors affect the mouth-exhaled NH3 concentration: urea concentration, urease activity and oral fluid pH. Bacterial urease catalyses the hydrolysis of oral fluid urea to ammonia (NH4(+)+NH3). Oral fluid ammonia (NH4(+)+NH3) and pH determine the concentration of oral fluid NH3, which evaporates from oral fluid into gas phase and turns to mouth-exhaled NH3.

The objective of the study was to investigate the influence of serial administration of a carbohydrate (CHO) mouth rinse on performance, metabolic and perceptual responses during a cycle sprint. Twelve physically active males (mean (± SD) age: 23.1 (3.0) years, height: 1.83 (0.07) m, body mass (BM): 86.3 (13.5) kg) completed the following mouth rinse trials in a randomized, counterbalanced, double-blind fashion; 1. 8 x 5 second rinses with a 25 ml CHO (6% w/v maltodextrin) solution, 2. 8 x 5 second rinses with a 25 ml placebo (PLA) solution. Following mouth rinse administration, participants completed a 30 second sprint on a cycle ergometer against a 0.075 g·kg-1 BM resistance. Eight participants achieved a greater peak power output (PPO) in the CHO trial, resulting in a significantly greater PPO compared with PLA (13.51 ± 2.19 vs. 13.20 ± 2.14 W·kg-1, p < 0.05). Magnitude inference analysis reported a likely benefit (81% likelihood) of the CHO mouth rinse on PPO. In the CHO trial, mean power output (MPO) showed a trend for being greater in the first 5 seconds of the sprint and lower for the remainder of the sprint compared with the PLA trial (p > 0.05). No significant between-trials difference was reported for fatigue index, perceived exertion, arousal and nausea levels, or blood lactate and glucose concentrations. Serial administration of a CHO mouth rinse may significantly improve PPO during a cycle sprint. This improvement appears confined to the first 5 seconds of the sprint, and may come at a greater relative cost for the remainder of the sprint. Key points The paper demonstrates that repeated administration of a carbohydrate mouth rinse can significantly improve peak power output during a single 30 second cycle sprint. The ergogenic effect of the carbohydrate mouth rinse may relate to the duration of exposure of the oral cavity to the mouth rinse, and associated greater stimulation of oral carbohydrate receptors. The significant increase in peak power

the decrease of facial movements in peripheral facial paralysis and the resulting aesthetical sequels may have important emotional repercussions as a consequence to the functional deficit, and depending on the intensity of the clinical condition. Orofacial rehabilitation has as a purpose to favor the recovery of orofacial movements and to adequate and/or adapt orofacial functions and facial mimic. However, quantifying therapeutic results in an attempt to measure the muscle tonus is a challenge. Generally, the used forms of measurement are general and subjective. to propose the labial commissure angle as an anthropometric marker and to evaluate its reliability as an objective tool to evaluate the modification of the facial muscle tonus after rehabilitation. participants of the study were 20 patients presenting peripheral facial paralysis - level IV. The study was conducted using images from the photographical documentation taken fifteen days to one year post-onset of facial paralysis. The angle was measured by tracings determined by pre-established anthropometric facial points, such as the line between the glabella and the gnation and the crossing with the left and right chelion points determining an angle manually measured with a protractor on the photography. The average Labial Commissure Angle before treatment was of 101.70 and after rehabilitation of 93.80 (standard deviation, SD = 4.3). The statistical analysis indicated a significant difference (p < 0.001). the results obtained suggest that the Labial Commissure Angle allows the objective evaluation of facial muscle tonus modification.

The long and singular course of the inferior (recurrent) laryngeal nerve makes it very vulnerable to infiltration by tumors of various locations. In particular, mediastinal and pulmonary lesions must be considered in the case of left vocal chord palsy. Recurrent nerve paralysis caused by a tumor indicates advanced disease. We retrospectively reviewed the computed tomography (CT) findings in 29 patients with bronchogenic carcinoma or mediastinal tumors and recurrent nerve paralysis with respect to the site, size and extent of the tumor and the lymph node status. The review revealed a marked predominance of left upper lobe tumors with extensive lymph node metastases to the anterior mediastinum and the aortopulmonary window. The extent of mediastinal involvement exceeded the average involvement in a control group of 30 randomly selected patients with bronchogenic carcinoma at the time of presentation. In all patients CT demonstrated tumor tissue which could have caused the paralysis at one or more sites along the anatomical course of the recurrent nerve. In most cases the tumor was located at the aortic arch. The left paratracheal region, right paratracheal region and right pulmonary apex were affected in one case each. We conclude that in patients with cancer, CT is a suitable method for localizing a recurrent nerve lesion.

Psychogenic paralysis presents a real treatment challenge. Despite psychotherapy, physiotherapy, antidepressants, acupuncture, or hypnosis, the outcome is not always satisfactory with persistent symptoms after long-term follow-up. We conducted a retrospective study to assess clinical features and to propose an alternative treatment based on repetitive transcranial magnetic stimulation (rTMS). Seventy patients (44 F/26 M, mean age: 24.7 +/- 16.6 years) experienced paraparesis (57%), monoparesis (37%), tetraparesis (3%), or hemiparesis (3%). A precipitating event was observed in 42 patients, primarily as a psychosocial event or a physical injury. An average of 30 stimuli over the motor cortex contralateral to the corresponding paralysis was delivered at low frequency with a circular coil. The rTMS was effective in 89% of cases, with a significantly better outcome for acute rather than chronic symptoms. In conclusion, motor cortex rTMS seem to be very effective in patients with psychogenic paralysis and could be considered a useful therapeutic option.

In the pediatric patient population, both the pathology and the surgical managements of seventh cranial nerve palsy are complicated by the small size of the patients. Adding to the technical difficulty is the relative infrequency of the diagnosis, thus making it harder to become proficient in the management of the condition. The magnitude of the functional and aesthetic deficits these children manifest is significantly troubling to both the patient and the parents, which makes immediate attention, treatment, and functional restoration essential. A literature search using PubMed (http://www.pubmed.org) was undertaken to identify the current state of surgical management of pediatric facial paralysis. Although a multitude of techniques have been used, the ideal reconstructive procedure that addresses all of the functional and cosmetic needs of these children has yet to be described. Certainly, future research and innovative thinking will yield progressively better techniques that may, one day, emulate the native facial musculature with remarkable precision. The necessity for surgical intervention in children with facial nerve paralysis differs depending on many factors including the acute/chronic nature of the defect as well as the extent of functional and cosmetic damage. In this article, we review the surgical procedures that have been used to treat pediatric facial nerve paralysis and provide therapeutic facial reanimation. Copyright © 2011 Elsevier Inc.

Certain tick species including Ixodes holocyclus can inoculate neurotoxins that induce a rapid, ascending flaccid paralysis in animals. Rhipicephalus sanguineus, the most widespread tick of dogs, is recognized as a vector of several pathogens causing diseases in dogs and humans. A single report suggests its role as cause of paralysis in dogs. This study presents the clinical history of 14 young dogs heavily infested by R. sanguineus (intensity of infestation, 63-328) in an endemic area of southern Italy. During May to June of 2011, dogs were presented at the clinical examination with neurological signs of different degrees (e.g., hind limb ataxia, generalized lethargy, and difficulty in movements). All animals were treated with acaricides and by manual tick removal but ten of them died within a day, displaying neurological signs. The other 4 dogs recovered within 3 days with acaricidal and supportive treatment. Twelve dogs were positive by blood smear examination for Hepatozoon canis with a high parasitemia, two also for Babesia vogeli and two were negative for hemoparasites. Low-grade thrombocytopenia, hypoalbuminemia, and pancytopenia were the haematological alterations most frequently recorded. Other causes of neurological disease in dogs were excluded and the diagnosis of tick paralysis by R. sanguineus was confirmed (ex juvantibus) by early and complete recovery of 4 dogs following acaricidal treatment and tick removal.

Introduction: Unilateral vocal cord paralysis (UVCP) is not an uncommon finding. Several procedures are available to manage glottal insufficiency. We conducted a clinical trial to evaluate the outcome of fat injection laryngoplasty. Materials and Methods: Liposuctioned lower abdomen fat was injected for augmentation of paralyzed vocal cord in 20 patients with UVCP. Autologous fat was harvested with an 18G needle and a 20-ml disposable syringe using a liposuction technique. Clinical follow-up after the injection was carried out from 1 to 6–21 months Results: Voice and glottal protective function were significantly improved after the surgery. Vocal elements were immediately improved after the surgery, and after 1 year of follow-up. Conclusion: Fat injection laryngoplasty by liposuction is simple, safe, effective and has a low cost for patients with UVCP with aspiration and breathy voice dysphonia. PMID:27429951

Our purpose was to examine the effectiveness of carbohydrate and caffeine mouth rinses in enhancing repeated sprint ability. Previously, studies have shown that a carbohydrate mouth rinse (without ingestion) has beneficial effects on endurance performance that are related to changes in brain activity. Caffeine ingestion has also demonstrated positive effects on sprint performance. However, the effects of carbohydrate or caffeine mouth rinses on intermittent sprints have not been examined previously. Twelve males performed 5 × 6-s sprints interspersed with 24 s of active recovery on a cycle ergometer. Twenty-five milliliters of either a noncaloric placebo, a 6% glucose, or a 1.2% caffeine solution was rinsed in the mouth for 5 s prior to each sprint in a double-blinded and balanced cross-over design. Postexercise maximal heart rate and perceived exertion were recorded, along with power measures. A second experiment compared a combined caffeine-carbohydrate rinse with carbohydrate only. Compared with the placebo mouth rinse, carbohydrate substantially increased peak power in sprint 1 (22.1 ± 19.5 W; Cohen's effect size (ES), 0.81), and both caffeine (26.9 ± 26.9 W; ES, 0.71) and carbohydrate (39.1 ± 25.8 W; ES, 1.08) improved mean power in sprint 1. Experiment 2 demonstrated that a combination of caffeine and carbohydrate improved sprint 1 power production compared with carbohydrate alone (36.0 ± 37.3 W; ES, 0.81). We conclude that carbohydrate and (or) caffeine mouth rinses may rapidly enhance power production, which could have benefits for specific short sprint exercise performance. The ability of a mouth-rinse intervention to rapidly improve maximal exercise performance in the absence of fatigue suggests a central mechanism.

Herpes simplex virus type 1 (HSV-1) has been proven to be a cause of Bell's palsy; however, the underlying pathophysiology of the facial nerve paralysis is not fully understood. We established a mouse model with facial nerve paralysis induced by HSV-1 infection simulating Bell's palsy and investigated the pathophysiology of the facial nerve paralysis. The time course of the R1 latency in the blink reflex tests paralleled the recovery of the facial nerve paralysis well, whereas electroneurographic recovery tended to be delayed, compared to that of the paralysis; these responses are usually seen in Bell's palsy. On histopathologic analysis, intact, demyelinated, and degenerated nerves were intermingled in the facial nerve in the model. The similarity of the time course of facial nerve paralysis and the electrophysiological results in Bell's palsy and the model strongly suggest that the pathophysiological basis of Bell's palsy is a mixed lesion of various nerve injuries.

Burning mouth syndrome (BMS) is a chronic oral pain or burning sensation affecting the oral mucosa, often unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women and may be accompanied by xerostomia and altered taste. Burning mouth syndrome is characterized by an intense burning or stinging sensation, preferably on the tongue or in other areas of mouth. This disorder is one of the most common, encountered in the clinical practice. This condition is probably of multifactorial origin; however the exact underlying etiology remains uncertain. This article discusses several aspects of BMS, updates current knowledge about the etiopathogenesis and describes the clinical features as well as the diagnosis and management of BMS patients.

There are various reasons for paralysis of the vocal folds, which consequently imposes great demands on differential diagnostics. Angiocardiopathies are regarded as very rare cases of etiopathogenesis. In the present case, a persistent arterial duct could be identified as the reason for the paralysis of the left recurrent nerve of a 59-year-old female patient. The necessity of interdisciplinary diagnostics going beyond the field of otorhinolaryngology is emphasized, especially in cases of a paralysis of the recurrent nerve.

After general anesthesia, peripheral nerve paralysis is a rare complication. The frequently damaged nerves including: branches of the brachial plexus, the ulnar, radial and common peroneal nerves, and sometimes the facial nerve. The radial nerve is the most infrequently damaged one, accounting for only 3% of nerve damage. We report a case of radial nerve paralysis due to self retractor during abdominal operation, its clinical findings, and review of the literature on peripheral nerve paralysis.

Burning mouth syndrome is a condition in which the patient perceives a sensation of intraoral burning, typically of the anterior tongue. This article presents a case report of a patient presenting for orofacial pain evaluation in whom ciguatera neurotoxin poisoning is diagnosed. The clinician should be aware of neurotoxin poisoning as a possible cause of symptoms of burning mouth, especially among patients who have recently traveled to a tropical area. Recognition of this condition in this case highlights the need for a detailed and accurate patient history.

Background Hyperkalaemic paralysis due to renal failure is a rare but potentially life threatening event. Case presentation We present a patient who had sudden onset ascending flaccid paralysis. The EMS first diagnosis was acute ST-elevation myocardial infarction based on an EKG. In the emergency room (ER) due to careful history taking, serum electrolytes and repeat EKG a correct diagnosis was made and both hyperkalemia and paralysis were treated on time. Conclusion Hyperkalaemic paralysis is rare. One must keep it in the back of the mind especially in the case of renal failure patients to avoid misdiagnosing a rapidly fatal but yet completely reversible condition. PMID:18845006

We report a case of a preterm neonate born at 26 weeks' of gestation diagnosed with unilateral diaphragmatic paralysis. This paralysis was a consequence of a phrenic nerve injury due to extravasation of hyperosmolar parenteral nutrition fluid in the upper thorax. Chest X-rays and ultrasonography confirmed the diagnosis. The neonate was treated with prolonged respiratory support and did not require surgical treatment. This report describes a case of hemidiaphragmatic paralysis as a complication of central venous catheter insertion. In neonates, spontaneous recovery of diaphragmatic paralysis is possible. This study concludes that recovery of extravasation injury-induced phrenic nerve palsy in the context of conservative management is possible. PMID:28405492

Sleep paralysis is a relatively common but under-researched phenomenon. In this paper we examine prevalence in a UK sample and associations with candidate risk factors. This is the first study to investigate the heritability of sleep paralysis in a twin sample and to explore genetic associations between sleep paralysis and a number of circadian expressed single nucleotide polymorphisms. Analyses are based on data from the Genesis1219 twin/sibling study, a community sample of twins/siblings from England and Wales. In total, data from 862 participants aged 22-32 years (34% male) were used in the study. This sample consisted of monozygotic and dizygotic twins and siblings. It was found that self-reports of general sleep quality, anxiety symptoms and exposure to threatening events were all associated independently with sleep paralysis. There was moderate genetic influence on sleep paralysis (53%). Polymorphisms in the PER2 gene were associated with sleep paralysis in additive and dominant models of inheritance-although significance was not reached once a Bonferroni correction was applied. It is concluded that factors associated with disrupted sleep cycles appear to be associated with sleep paralysis. In this sample of young adults, sleep paralysis was moderately heritable. Future work should examine specific polymorphisms associated with differences in circadian rhythms and sleep homeostasis further in association with sleep paralysis.
McNally and Clancy [McNally, R. J., & Clancy, S. A. (2005). Sleep paralysis in adults reporting repressed, recovered, or continuous memories of childhood sexual abuse. Journal of Anxiety Disorders, 19, 595-602.] conducted a study on sleep paralysis among adults reporting either repressed, recovered, or continuous memories of sexual abuse. I suggest that the study be replicated with a larger number of recovered memory subjects (those who believe that they have recovered memories of childhood sexual abuse) who experienced sleep paralysis, using more neutral wording in order to identify the phenomenon of sleep paralysis.

In unilateral vocal cord paralysis (UVCP), hoarseness is usually the leading symptom; however, the diminished airway might lead to breathing problems as well, especially with exertion. The application of the classic resection glottis enlarging or medialization procedures might shift the breathing and/or the voice to a worse condition. The non-destructive endoscopic arytenoid abduction lateropexy (EAAL) might be a solution for this problem. The aim of our study was to analyze the phonatory and respiratory outcomes of this treatment concept. The first year phoniatric [Jitter, Shimmer, harmonics-to-noise ratio (HNR), maximum phonation time (MPT), fundamental frequency (F 0), Voice Handicap Index (VHI), Dysphonia Severity Index (DSI), Global-Roughness-Breathiness scale (GRB)], peak inspiratory flow (PIF), and quality of life (QoL) were evaluated in ten UVCP patients treated by EAAL for dyspnea generally presented on exertion. PIF, Jitter, QoL, GRB, and VHI significantly improved. DSI, HNR, and MPT got non-significantly better. F 0 slightly increased in all patients, a mild deterioration of shimmer was observed. These results prove that improving respiratory function is not necessarily associated with a deterioration in voice quality. The EAAL provides a significant improvement in breathing and the vibratory parameters of the postoperative, more tensed and straightened vocal cords proved to be more advantageous than the original (para) median 'loose' position. The over-adduction of the contralateral side more or less compensates for the disadvantageous, more lateral position of the operated side. EAAL might be an alternative treatment for unilateral vocal cord paralysis associated with breathing problems.

Morbidly obese patients show impaired pulmonary function during anesthesia and paralysis, partly due to formation of atelectasis. This study analyzed the effect of general anesthesia and three different ventilatory strategies to reduce the amount of atelectasis and improve respiratory function. Thirty patients (body mass index 45 +/- 4 kg/m) scheduled for gastric bypass surgery were prospectively randomized into three groups: (1) positive end-expiratory pressure of 10 cm H2O (PEEP), (2) a recruitment maneuver with 55 cm H2O for 10 s followed by zero end-expiratory pressure, (3) a recruitment maneuver followed by PEEP. Transverse lung computerized tomography scans and blood gas analysis were recorded: awake, 5 min after induction of anesthesia and paralysis at zero end-expiratory pressure, and 5 min and 20 min after intervention. In addition, spiral computerized tomography scans were performed at two occasions in 23 of the patients. After induction of anesthesia, atelectasis increased from 1 +/- 0.5% to 11 +/- 6% of total lung volume (P < 0.0001). End-expiratory lung volume decreased from 1,387 +/- 581 ml to 697 +/- 157 ml (P = 0.0014). A recruitment maneuver + PEEP reduced atelectasis to 3 +/- 4% (P = 0.0002), increased end-expiratory lung volume and increased Pao2/Fio2 from 266 +/- 70 mmHg to 412 +/- 99 mmHg (P < 0.0001). PEEP alone did not reduce the amount of atelectasis or improve oxygenation. A recruitment maneuver + zero end-expiratory pressure had a transient positive effect on respiratory function. All values are presented as mean +/- SD. A recruitment maneuver followed by PEEP reduced atelectasis and improved oxygenation in morbidly obese patients, whereas PEEP or a recruitment maneuver alone did not.

Suction feeding is the most common form of prey capture across aquatic feeding vertebrates and many adaptations that enhance efficiency and performance are expected. Many suction feeders have mechanisms that allow the mouth to form a planar and near-circular opening that is believed to have beneficial hydrodynamic effects. We explore the effects of the flattened and circular mouth opening through computational fluid dynamics simulations that allow comparisons with other mouth profiles. Compared to mouths with lateral notches, we find that the planar mouth opening results in higher flow rates into the mouth and a region of highest flow that is positioned at the centre of the mouth aperture. Planar mouths provide not only for better total fluid flow rates through the mouth but also through the centre of the mouth near where suction feeders position their prey. Circular mouths are shown to provide the quickest capture times for spherical and elliptical prey because they expose the prey item to a large region of high flow. Planar and circular mouths result in higher flow velocities with peak flow located at the centre of the mouth opening and they maximize the capacity of the suction feeders to exert hydrodynamic forces on the prey.

Avalle, C; Fischer-Brandies, H; Schmid, R G
56 patients suffering from connatal cerebral palsy were treated with removable orthodontic appliances possessing stimulation areas according to Castillo-Morales. The intention was to improve the well-known orofacial dysfunctions of these patients. The evaluation of a standard treatment schedule leads to the following statements: The tongue and lip control can be improved in many patients, as well as the chewing and swallowing pattern, the speech and the problem of saliva running out of the mouth. The resting-position of the tongue is normalized in some of the cases. The habit of an open mouth can hardly ever be improved. In a small number of patients some parameters of orofacial function worsened during treatment; in most of these cases, however, a general improvement of orofacial function justified further treatment with palatal plates.

Obstetric brachial plexus paralysis (OBPP) has been associated with shoulder deformities, scapular growth, and shoulder function impairment. The absence of balanced muscular forces acting on the scapula has been considered responsible for scapula dysplasia and impaired growth as compared with the normal side. Scapula growth impairment may also lead to shoulder and upper extremity dysfunction. This study aims at showing the association of primary nerve reconstruction with the restoration of scapular bone growth potential. This is a retrospective review of 73 patients with OBPP who underwent primary shoulder reconstruction. Patients were categorized for assessment and analysis into group A, global paralysis; group B, Erb's palsy; and group C, Erb's palsy with C7 root involvement. Scapular posteroanterior and lateral X-rays were obtained in which four scapula dimensions were manually measured. The growth discrepancy depending on the applied treatment was investigated. The highest improvement was noted in scapular height in the Erb's palsy group who underwent simultaneous neurotization of the suprascapular and axillary nerves. The oblique axis was more improved in the Erb's palsy group while both big and small widths were more improved in the Erb's palsy with C7 root involvement group in patients who underwent concomitant neurotization of the suprascapular and the axillary nerves. Functional improvement correlated positively with growth improvement in all groups and scapular dimensions. Scapula growth and shoulder function improvement were higher in patients with Erb's palsy. Simultaneous axillary and suprascapular nerve neurotization provided the best outcome in both functional and growth restoration.

The aim of this study was to describe the association between climate, weather and the occurrence of canine tick paralysis, feline tick paralysis and canine parvovirus in Australia. The Southern Oscillation Index (SOI) and monthly average rainfall (mm) data were used as indices for climate and weather, respectively. Case data were extracted from a voluntary national companion animal disease surveillance resource. Climate and weather data were obtained from the Australian Government Bureau of Meteorology. During the 4-year study period (January 2010-December 2013), a total of 4742 canine parvovirus cases and 8417 tick paralysis cases were reported. No significant (P ≥ 0.05) correlations were found between the SOI and parvovirus, canine tick paralysis or feline tick paralysis. A significant (P < 0.05) positive cross-correlation was found between parvovirus occurrence and rainfall in the same month (0.28), and significant negative cross-correlations (-0.26 to -0.36) between parvovirus occurrence and rainfall 4-6 months previously. Significant (P < 0.05) negative cross-correlations (-0.34 to -0.39) were found between canine tick paralysis occurrence and rainfall 1-3 months previously, and significant positive cross-correlations (0.29-0.47) between canine tick paralysis occurrence and rainfall 7-10 months previously. Significant positive cross-correlations (0.37-0.68) were found between cases of feline tick paralysis and rainfall 6-10 months previously. These findings may offer a useful tool for the management and prevention of tick paralysis and canine parvovirus, by providing an evidence base supporting the recommendations of veterinarians to clients thus reducing the impact of these diseases.

Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD). Infection with EV71 is occasionally associated with severe neurological diseases such as acute encephalitis, acute flaccid paralysis, and cardiopulmonary failure. Because cellular receptors for viruses play an important role in cell, tissue, and species tropism, it is important to identify and characterize the receptor molecule. Recently, cellular receptors and host factors that stimulate EV71 infection have been identified. Several lines of evidence suggest that scavenger receptor class B, member 2 (SCARB2) plays critical roles in efficient EV71 infection and the development of disease in humans. In this review, we will summarize the findings of recent studies on EV71 infection and on the roles of SCARB2.

To compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding. Two hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups. After treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group

In this study, we evaluated the palatability of orally disintegrating tablets (ODTs) containing core granules with different particle sizes, coating, and types of materials using visual analog scales (VAS). Tableting the core granules into ODTs reduced rough mouth feel and improved overall palatability compared to the ingestion of core granules alone. Moreover, the evaluation performed immediately after spitting out ODTs demonstrated differences in rough mouth feel between ODTs containing placebo and core granules. Rough mouth feel was found to be significantly more intense with core granules with particle sizes ≥ 200 μm. Since ODTs may contain taste-masked particles, palatability of ODTs containing coated core granules was also evaluated. Although coating with polymers impairs palatability, it was improved by coating the outer layer with d-mannitol. The effects on palatability of materials constituting core granules were also evaluated, with reduced rough mouth feel observed with core granules composed of water-soluble additives. Based on these data, receiver operating characteristic analysis was performed to determine the threshold VAS scores at which the subjects felt roughness and discomfort. In addition, the threshold particle size of the core granule contained within the ODT required for feeling roughness was determined to be 244 μm. This study elucidated the effect of the properties of masking particles on the rough mouth feel and palatability of ODTs. Copyright © 2015 Elsevier B.V. All rights reserved.

Mouth cancer is a major health problem. Multiple risk factors for developing mouth cancer have been studied and include history of tobacco and alcohol abuse, age over 40, exposure to ultraviolet radiation, human papilloma virus infection (HPV), nutritional deficiencies, chronic irritation, and existence or oral potentially malignant lesions such as leukoplakia and lichen planus. An important risk factor for mouth cancer is chronic immunosuppression and has been extensively reported after solid organ transplantation as well as HIV-infected patients. Diagnosis of inflammatory bowel disease (IBD) is not yet considered as a risk factor for oral cancer development. However, a significant number of patients with IBD are receiving immunosuppressants and biological therapies which could represent potential oral oncogenic factors either by direct oncogenic effect or by continuous immunosuppression favoring carcinogenesis, especially in patients with HPV(+) IBD. Education on modifiable risk behaviors in patients with IBD is the cornerstone of prevention of mouth cancer. Oral screening should be performed for all patients with IBD, especially those who are about to start an immunosuppressant or a biologic. © 2015 John Wiley & Sons A/S.

This paper proposes the use of an implantable solenoid actuator to create a more natural eyelid closure over current lid loading therapies in patients with facial nerve paralysis (FNP). The actuator works by moving a magnet when a solenoid is activated. This is used to tension a sling applied to the upper eyelid which closes the eye. The sling design has been described elsewhere and creating eye closure using it requires a force of 627 (± 128) mN over a movement of approximately 6 mm. The actuator described here was able to successfully achieve these parameters and repeatedly perform eyelid closure in a cadaveric rabbit model. Device limitations and future improvements have also been identified and discussed.

Professor HE Tianyou's unique understanding and treatment characteristics for intractahle facial paralysis are introduced. In clinical practice professor HE highly values acupoint selection and manipulation application, and integrates Chinese and western medicine to flexibly choose acupoints and formulate prescriptions according to syndrome differentiation and location differentiation, besides, he creates several specialized manipulation methods including "tug-of war opposite acupuncture method" and "tractive flash cupping". Based on strengthening body and dredging collaterals. more attention is given on stimulation to local paralyzed facial nerves; meanwhile acupuncture and medication are combined to improve clinical efficacy. During the treatment, the important role of psychological counseling on patient's anxiety is emphasized, and comprehensive treatment is given physically and psychologically in order to achieve the purpose of total rehabilitation.

Observations and analysis of glottal characteristics are critical in choosing the best modality for surgery in patients with unilateral vocal fold paralysis (UVP). This study suggests that multiple glottal characteristics influence the vocal product in patients with UVP. In addition to the horizontal position of the paralyzed vocal fold (deviation from the midline), the glottal area, degree of bowing of the paralyzed and contralateral vocal folds, maximum separation between vocal folds, compensatory glottal maneuvers, and the vertical glottic closure plane significantly influenced the quality of the voice. Clinicians should be aware of these observations to facilitate treatment planning and assessment of the results of surgical procedures used to improve voice quality in cases of UVP.

Paralysis of ulnar, median and radial nerves is seen in less than 1% of those affected with leprosy. This condition is a particular challenge for the surgeon, physiotherapist, and patient. A retrospective chart review was conducted at the Green Pastures Hospital and Rehabilitation Centre (GPHRC) and Anandaban Leprosy Hospital (ALH) in Nepal, and results were graded by the system outlined by Sundararaj in 1984. Thirty-one patients were identified, and 21 charts were available for review. Excellent or good results were obtained in 93% of patients for wrist extension, 85% of patients for finger extension, 90% of patients for thumb extension, 71% of patients for intrinsic reconstruction, and 63% of patients for thumb opposition reconstruction. These results are reasonable but inferior to those obtained by Sundararaj in his study. Surgical intervention offers a very significant improvement in function in these very difficult hands. Intensive physiotherapy is required both pre- and postoperatively.

Eleven episodes of severe hyponatremia secondary to hiccup-induced potomania were recorded in 3 years in a man who had essential hypertension, a low protein intake and a normal diluting ability. Paradoxical increase in hematocrit and plasma protein with acute extensive natriuresis was associated as well as urine potassium loss and hypokalemia producing paralysis in 1 episode. During a chronic water loading test, the defect in water excretion was related to a low urine solute delivery which was partially reverted by the natriuretic response to plasma volume expansion, promoting water diuresis. In acute water intoxication, this natriuretic response was exaggerated, producing a brisk water diuresis. Plasma volume was rapidly normalized but without any improvement in plasma sodium due to the concomitant negative sodium balance. Thus, water diuresis persisted until plasma volume was significantly contracted. Potassium loss appeared to be related to sodium excretion. Metabolic disturbances have not reoccurred despite persistent hiccup and potomania during 2 years of urea therapy.

Four Quarter Horse foals ranging in age from 6 days to 2 months were determined to have upper airway stridor secondary to polymyopathy suspected to be hyperkalemic periodic paralysis. Electromyography revealed spontaneous muscle activity in all muscles examined. Electromyographic findings were similar in the dams of 3 foals (No. 1, 3 and 4). Hyperkalemia was found in foals 1 and 4. Endoscopically, the upper airway stridor in foals 1 and 3 was confirmed to be attributable to laryngeal and pharyngeal collapse or spasm. Foals 1, 2, and 3 were treated with acetazolamide. Foal 4 was not treated, at the owner's request. Foals 2 and 3 improved with treatment, foal 4's condition was static, and foal 1 required a tracheostomy and laryngeal surgery to manage its upper airway stridor.

Dural prostate metastases (DPM) are a rare manifestation of metastatic prostate cancer seen in approximately one to six percent of cases. Presenting symptoms may include signs of elevated intracranial pressure, headache, altered mental status, or cranial nerve palsies. Hearing loss, sensory changes, dysarthria, and dysphagia are rare symptoms in DPM that were present in our patient. We present a case of a 58-year-old male with a known diagnosis of adenocarcinoma of the prostate presenting with symptoms of acute exacerbation of chronic obstructive pulmonary disease (COPD), sub-acute right-sided hearing loss, and right-sided facial paralysis. Over the course of hospitalization, his neurological symptoms worsened and he developed dysarthria, dysphagia, facial numbness, and worsening back pain. He also appeared more withdrawn and lethargic. The symptoms prompted a neurological evaluation and a magnetic resonance imaging (MRI) revealed multiple areas of bone marrow signal abnormality compatible with osseous metastatic disease. There was extensive smooth dural thickening as well as focal nodular thickening, both consistent with dural metastases. The patient was treated with corticosteroids and external beam radiation therapy (EBRT) with improvement in his back pain and facial paralysis. He died two weeks after completing EBRT. Although rare, DPM should be suspected in males over 50 years of age presenting with neurological symptoms. An MRI with gadolinium is most helpful in delineating the presence and extent of dural and calvarial involvement. Corticosteroids and EBRT have been shown to improve neurological function in up to 67% of patients. However, median survival post-radiation remains approximately three months. PMID:28409073

To observe the therapeutic effect and to explore the best opportunity of acupuncture on spontaneous facial paralysis in acute stage. By prospective cohort study, 80 patients were divided into an observation group (n = 59) and a control group (n = 21). The course of disease was less than 5 days in the observation group and more than 7 days in the control group and had not received acupuncture treatment. They were all treated with acupuncture at Sibai (ST 2), Dicang (ST 4), Jiache (ST 6) and Cuanzhu (BL 2) etc. for 8 weeks. The facial nerve function grading (House-Brackmann, HB) and facial disable index (FDI) before treatment, 8 days after onset, 2, 4, 6, 8 weeks and 3 months after treatment were evaluated. Both two groups could decrease HB grading and increase FDI score (all P < 0.05), and the observation group was superior to the control group in improvement degree (all P < 0.05). The cured rate of 86.4% (51/59) in the observation group was superior to that of 76.2% (16/21) in the control group, with significant difference between the two groups (P < 0.05). Compared with the control group, the treatment time of cured patients in the observation group was shorter [(25.98 +/- 11.25) days vs (39.31 +/- 13.07) days, P < 0.01], and the incidence of sequelae of 5.1% (3/59) in the observation group was lower than that of 9.5% (2/21) in the control group (P < 0.05). Acupuncture can improve the therapeutic effect, shorten the treatment course and reduce the sequelae incidence of spontaneous facial paralysis in acute stage.

The use of spring-loaded mouth gags in cats can be associated with the development of central neurological deficits, including blindness. In this species, the maxillary arteries are the main source of blood supply to the retinae and brain. Spring-loaded gags generate constant force after placement that could contribute to bulging of the soft tissues between the mandible and the tympanic bulla. Under these circumstances, the maxillary arteries can become compressed as they course between these osseous structures. Smaller gags that might apply less force to the mouth were investigated to determine if they preserved maxillary artery blood flow. Six healthy adult cats were anesthetized. Electroretinography (ERG) and magnetic resonance angiography (MRA) were performed without the use of a mouth gag and during submaximal (plastic mouth gags of 20, 30 and 42 mm in length between canine teeth) and maximal mouth opening. Maximal mouth opening produced alterations in ERG waveforms consistent with circulatory compromise in 1/6 cats and reductions in signal intensity during MRA in 4/6 cats. Placement of a 42 mm plastic gag produced a reduction in MRA signal in 1/6 cats. No changes were observed with smaller gags. The force applied against the mouth was significantly higher with the spring-loaded gag than with any other gags. The use of a smaller mouth gags was associated with fewer alterations of indicators of maxillary artery blood flow. Nevertheless, a 42 mm plastic gag, equivalent to the size of a needle cap, resulted in an abnormal MRA in one cat. Copyright © 2014 Elsevier Ltd. All rights reserved.

Saliva is vital for the maintenance of normal oral physiology and mucosal health. The loss of salivary function can have far-reaching consequences, as observed with dry mouth, which is associated with increased orodental disease, speech impairment, dysphagia, and a significant negative effect on quality of life. The timely diagnosis of oral dryness is vital for the management of orodental disease and any associated often-undiagnosed systemic disease (e.g., Sjögren syndrome). Our aim was to investigate differences in mucin glycoproteins and saliva rheological properties between sufferers and nonsufferers of dry mouth in order to understand the relationship between saliva composition, rheological properties, and dryness perception and provide additional potential diagnostic markers. All patients exhibited objective and subjective oral dryness, irrespective of etiology. Over half of the patients (n = 20, 58.8%) had a saliva secretion rate above the gland dysfunction cutoff of 0.1 mL/min. Mucin (MUC5B and MUC7) concentrations were generally similar or higher in patients. Despite the abundance of these moisture-retaining proteins, patients exhibited reduced mucosal hydration (wetness) and significantly lower saliva spinnbarkeit (stringiness), suggesting a loss of the lubricating and retention/adhesion properties of saliva, which, at least partially, are associated with mucin glycoproteins. Over 90% of patients with dry mouth (DMPs) consistently had unstimulated whole mouth saliva (UWMS) spinnbarkeit below the proposed normal cutoff (10 mm). Further analysis of mucins revealed the reduced glycosylation of mucins in DMPs compared to healthy controls. Our data indicate that UWMS mucin concentrations are not reduced in dry mouth but that the mucin structure (glycosylation) is altered. UWMS from DMPs had reduced spinnbarkeit, the assessment of which, in conjunction with sialometry, could improve sensitivity for the diagnosis of dry mouth. Additionally, it may be useful to

Background: Poliomyelitis is still an endemic disease in many areas of the world including Africa and South Asia. Iran is polio free since 2001. However, due to endemicity of polio in neighboring countries of Iran, the risk of polio importation and re-emergence of wild polio virus is high. Case definition through surveillance system is a well-defined method for maintenance of polio eradication in polio free countries. Methods: In a cross-sectional survey from 2007 to 2013, we reviewed all the records of under 15 years old patients reported to Acute Flaccid Paralysis Committee (AFPC) in Isfahan province, Iran. All cases were visited by members of the AFPC. Three stool samples were collected from each reported case within 2 weeks of onset of paralysis and sent to National Polio Laboratory in Tehran, Iran, for poliovirus isolation. Data were analyzed by SSPS software (version 22). Student's t-test and Chi-square was used to compare variables. Statistical significance level was set at P < 0.05. Results: In this 6-year period 85 cases were analyzed, 54 patients were male (63.5%) and 31 were female (36.5%). The mean age of patients was 5.7 ± 3.9 years. The most common cause of paralysis among these patients was Guillian–Barré syndrome (83.5%). We did not found any poliomyelitis caused by wild polio virus. Only one case of vaccine associated poliomyelitis was reported. Conclusion: Since 1992, Iran has a routine and high percent coverage of polio vaccination program for infants (>94%), with six doses of oral polio vaccine (OPV). Accurate surveillance for poliomyelitis is essential for continuing eradication. PMID:26015925

Unilateral vocal fold paralysis (UVP) occurs related to recurrent laryngeal nerve (RLN) impairment associated with impaired swallowing, voice production, and breathing functions. The majority of UVP cases occur subsequent to surgical intervention with approximately 12-42% having no known cause for the disease (i.e., idiopathic). Approximately two-thirds of those with UVP exhibit left-sided injury with the average onset at ≥50 yr of age in those diagnosed as idiopathic. Given the association between the RLN and the subclavian and aortic arch vessels, we hypothesized that changes in vascular tissues would result in increased aortic compliance in patients with idiopathic left-sided UVP compared with those without UVP. Gated MRI data enabled aortic arch diameter measures normalized to blood pressure across the cardiac cycles to derive aortic arch compliance. Compliance was compared between individuals with left-sided idiopathic UVP and age- and sex-matched normal controls. Three-way factorial ANOVA test showed that aortic arch compliance (P = 0.02) and aortic arch diameter change in one cardiac cycle (P = 0.04) are significantly higher in patients with idiopathic left-sided UVP compared with the controls. As previously demonstrated by other literature, our finding confirmed that compliance decreases with age (P < 0.0001) in both healthy individuals and patients with idiopathic UVP. Future studies will investigate parameters of aortic compliance change as a potential contributor to the onset of left-sided UVP.NEW & NOTEWORTHY Unilateral vocal fold paralysis results from impaired function of the recurrent laryngeal nerve (RLN) impacting breathing, swallowing, and voice production. A large proportion of adults suffering from this disorder have an idiopathic etiology (i.e., unknown cause). The current study determined that individuals diagnosed with left-sided idiopathic vocal fold paralysis exhibited significantly greater compliance than age- and sex-matched controls

River mouths, shoreline locations where fluvial and coastal sediments are partitioned via erosion, trapping, and redistribution, are responsible for the ultimate sedimentary architecture of deltas and, because of their dynamic nature, also pose great management and engineering challenges. To investigate the interaction between fluvial and littoral processes at wave-dominated river mouths, we modeled their morphologic evolution using the coupled hydrodynamic and morphodynamic model Delft3D-SWAN. Model experiments replicate alongshore migration of river mouths, river mouth spit development, and eventual spit breaching, suggesting that these are emergent phenomena that can develop even under constant fluvial and wave conditions. Furthermore, we find that sediment bypassing of a river mouth develops though feedbacks between waves and river mouth morphology, resulting in either continuous bypassing pathways or episodic bar bypassing pathways. Model results demonstrate that waves refracting into the river mouth bar create a zone of low alongshore sediment transport updrift of the river mouth, which reduces sediment bypassing. Sediment bypassing, in turn, controls the river mouth migration rate and the size of the river mouth spit. As a result, an intermediate amount of river discharge maximizes river mouth migration. The fraction of alongshore sediment bypassing can be predicted from the balance between the jet and the wave momentum flux. Quantitative comparisons show a match between our modeled predictions of river mouth bypassing and migration rates observed in natural settings.

Background. Parsonage-Turner syndrome, or neuralgic amyotrophy (NA), is an acute brachial plexus neuritis that typically presents with unilateral shoulder pain and amyotrophy but also can affect other peripheral nerves, including the recurrent laryngeal nerve. Idiopathic vocal fold paralysis (VFP) represents approximately 12% of the VFP cases and recurrence is extremely rare. Methods and Results. We report a man with isolated recurrent unilateral right VFP and a diagnosis of NA years before. Conclusions. We emphasize that shoulder pain and amyotrophy should be inquired in any patient suffering from inexplicable dysphonia, and Parsonage-Turner syndrome should be considered in the differential diagnosis of idiopathic VFP.

The supernatural fears associated with the experience of isolated sleep paralysis in the culture of developing countries is sometimes associated with the evolution of somatic symptoms of psychological origin in patients predisposed to neurotic illness. Patients rarely spontaneously volunteer these fears and doctors pay them scant attention. Illustrative case histories that demonstrate the dynamics of the clinical presentation, as well as the treatment approach, are highlighted. It is hoped that doctors in general medical practice and in psychological medicine in developing countries where belief in supernatural causation of illness is rife will consider these factors in order to provide more effective treatment.

This descriptive analytical ten year (1985-1994) retrospective study assessed the pattern of spinal cord paralysis (SCP) in the Fiji Islands utilising medical rehabilitation hospital data. Fiji Islands is an archipelago of 300 islands in the south western Pacific with a multi-ethnic population of over three quarters of a million. Rehabilitation of all SCP is provided at the Medical Rehabilitation Unit (MRU). Data was collected from medical records of new SCP (n = 140) admitted to MRU and analysed with Epi Info 5 assessing associations between cause and other variables. The incidence of new SCP admitted to the MRU was 18.7/million/year. There were 75 (53.6%) traumatic and 65 (46.4%) non-traumatic SCP. The incidence varied according to gender and ethnicity with Fijian male being at the highest (41.85) risk. Amongst traumatic SCP, 38.7% were due to falls, 25.3% motor vehicle accidents, 20% sports, 8% shallow water dive and 4% each deep sea diving and others, whereas among non-traumatic SCP, 52.3% were due to unknown causes, 32.3% infections, 9.2% neoplasms and 6.2% others. The male/female ratio was 4:1. The 16-30 year age group accounted for 35% of SCP. 31% had tetraplegia and 52.1% had complete lesions. The subset of the sample who experienced traumatic SCP were more likely to be employed, aged between 16-30 years at the time of paralysis and to have complete tetraplegia. Those who experienced incomplete paraplegia were more likely to be unemployed, aged 46-60 years and educated to primary level at the time of paralysis. There was a high proportion of complete spinal lesion when compared with other studies. The incidence of secondary complications such as pressure sores and UTI was also found to be high when compared with other studies. The results support the view that young Fijian males are most prone to sustaining traumatic spinal cord paralysis, and that there is a high incidence of secondary preventable complications. The need for preventative measures and

A 47 year old male was admitted in a comatose state. CT scan showed a haemorrhage in the right pulvinar thalamus descending into the right part of the lamina quadrigemina. He presented with anisocoria, prompt bilateral pupillary light reaction, and unilateral convergence paralysis contralateral to the lesion in combination with upward gaze palsy. During an observation period of two months, the convergence reaction returned to normal. MRI showed a lacunar lesion ventral to superior right colliculus. Angiography revealed an arteriovenous malformation (right posterior cerebral artery--sinus rectus) as the possible cause of the haemorrhage. Images PMID:1527550

Local anesthesia is widely used, in isolation or in conjunction with general anesthesia. The authors describe 2 adolescent patients presenting with absent brainstem reflexes and delayed awakening following elective foramen magnum decompression for Chiari Type I malformation. In both cases, neurological deficits were closely associated with the administration of a levobupivacaine field block following wound closure. In the absence of any structural or biochemical abnormalities, and with spontaneous recovery approximating the anesthetic half-life, the authors' observations are consistent with transient brainstem paralysis caused by perioperative local anesthetic infiltration.

The most common disorder of the facial nerve is acute idiopathic facial paralysis or Bell's palsy and there may be significant morbidity or incomplete recovery associated with severe cases. To assess the efficacy of aciclovir or similar agents for treating Bell's palsy. We searched the Cochrane Neuromuscular Disease Group register (searched April 2003), MEDLINE (from January 1966 to April 2003), EMBASE (from January 1980 to April 2003) and LILACS (from January 1982 to April 2003). We also contacted authors of identified trials. Randomised or quasi-randomised trials of aciclovir or valaciclovir therapy, alone or in combination with any other drug, in patients with Bell's palsy. We identified six randomised trials. Three studies met our inclusion criteria, including 246 patients. One study evaluated aciclovir with corticosteroid versus corticosteroid alone, another study evaluated aciclovir alone versus corticosteroid and a further study evaluated valaciclovir with corticosteroid versus corticosteroid alone or versus placebo alone. Incomplete recovery after one year: data were not available. An analysis was performed on data reported at the end of the study period in each trial. The results from one study four months after the start of treatment significantly favoured the treatment group, whilst the results of the study three months after the start of treatment significantly favoured the control group. The results from the second study at four months showed no statistically significant difference between the three groups.Adverse events: relevant data were not reported in any of the three trials.Complete facial paralysis six months after start of treatment: only one patient had complete paralysis upon entering one of the studies. This patient was assigned to the control group and the level of recovery attained was not reported.Motor synkinesis or crocodile tears one year after start of treatment: data were available up to a maximum of four months after onset of

Thyrotoxic hypokalemic periodic paralysis (THPP) is an endocrine emergency marked by recurrent attacks of muscle weakness associated with hypokalemia and thyrotoxicosis. Asiatic male patients are most often affected. On the other hand, African descents rarely present this disease. The case described shows an afrodescendant patient with hypokalemia and tetraparesis, whose diagnosis of hyperthyroidism was considered during this crisis. The THPP, although rare, is potentially lethal. Therefore, in cases of flaccid paresis crisis this diagnosis should always be considered, especially if associated with hypokalemia. In this situation, if no previous diagnosis of hyperthyroidism, this should also be regarded.

Tenofovir induced fanconi syndrome (FS) presenting as hypokalemic paralysis is an extremely rare complication in patients on anti-retroviral therapy. We report a 50-year-old male with acquired immunodeficiency syndrome on tenofovir-based anti-retroviral therapy who presented with acute onset quadriparesis. On evaluation, he was found to have hypokalemia with hypophosphatemia, glucosuria and proteinuria suggesting FS. He regained normal power in limbs over next 12 h following correction of hypokalemia. Ours would be the second reported case in India. PMID:26692618

Facial palsy is not an uncommon presentation to an emergency department. Whereas most patients will ultimately receive a diagnosis of Bell palsy (idiopathic peripheral seventh cranial nerve palsy), a subset will have an identifiable cause for their facial paralysis. Children are more likely to have an identifiable cause than are adults. We present a case in which a child presented with acute peripheral facial nerve palsy and was found to have temporal bone rhabdomyosarcoma. The key clinical finding was the presence of both 7th and 12th cranial nerve palsy.

The last case of wild polio virus transmission occurred in Akwa Ibom state in October 2001; however, combination high routine immunization coverage with OPV, high quality AFP surveillance, mass immunization campaign in which two doses of potent oral polio vaccine is administered to eligible children and mop-up campaigns in areas with identified immunization or surveillance gaps has help the state in maintaining a free polio status for over ten years. This study was carried out to describe the characteristics of reported acute flaccid paralysis cases between 2004 and 2009, and to evaluate the performance of the acute flaccid paralysis surveillance system using indicators recommended by the World Health Organization. A retrospective study was conducted among children, 0-15 years, by the World Health Organization (WHO) and Epidemiology unit of State Ministry of Health (SMOH), Uyo. The demographic characteristics and the results of isolation and identification of polio and other enteroviruses in stool samples sent to the WHO Polio Laboratory Ibadan for cases was analyzed. A total of 521 cases of AFP (270 males and 251 females) aged 0 month to=15 years were reported by the surveillance system between 2004 and 2009. Those below 5 years of age accounted for 82.5% of cases reported and investigated. Of the 521 cases investigated 512 (98.3%) received at least three doses of oral polio vaccine, while 9(1.7) never received any oral polio vaccine (zero-dose). In all 5.1% of the isolates were Sabin, 7.9% non polio enterovirus (NPEV) and 2.3% were classified by national expert committee as compatible with poliomyelitis. There was consistent and steady increase in three critical indicators; Non polio AFP rate in children <15 years from 4.5 to 6.4 per 100,000 population, proportion of AFP cases with 2 stool specimens collected within 14 days of onset of paralysis from 57% in 2005 to 91% in 2009 and proportion of Local Government Areas (Districts) meeting both core indicators from

Although etiology and pathology of symptomatic diaphragm paralysis and eventration are distinct, their treatments are the same: to reduce dysfunctional caudal excursion of the diaphragm during inspiration by plication. Minimally invasive diaphragm plication techniques have emerged as equally effective and less morbid alternatives to open plication. This review focuses on the etiology, pathophysiology, diagnosis, and treatment of diaphragmatic eventration or paralysis in adults.

To describe the characteristics of patients reported with acute flaccid paralysis between 1997 and 2002, and to evaluate the performance of the acute flaccid paralysis surveillance system using indicators recommended by the World Health Organization. Retrospective study. Department of Health, Hong Kong. Children aged younger than 15 years who were reported to the Department of Health between 1997 and 2002 with acute flaccid paralysis. Of 120 children with acute flaccid paralysis reported between 1997 and 2002, 42% were younger than 5 years of age. None of the cases were acute poliomyelitis or polio-compatible. A neurological cause was identified in 67.5% of cases, of which the most common was Guillain-Barre syndrome (42%), followed by transverse myelitis (15%). All except one of the performance indicators consistently met World Health Organization requirements and thus demonstrated the effectiveness of the acute flaccid paralysis surveillance programme. The acute flaccid paralysis notification rate consistently exceeded 1.0 per 100 000 population below 15 years of age. The requirement for adequate stool investigation was the single indicator that did not satisfy World Health Organization requirements. This highlighted the importance of maintaining physicians' awareness of acute flaccid paralysis surveillance. Hong Kong should remain vigilant for acute flaccid paralysis. The effective surveillance system and its evaluation may serve as a model for surveillance of other infectious diseases.

Vocal cord paralysis after tracheal intubation is rare. It causes severe hoarseness and aspiration, and delays recovery and discharge. Arytenoid cartilage dislocation and recurrent nerve paralysis are main causes of vocal cord paralysis. Physical stimulation of the tracheal tube as well as patient and surgical characteristics also contribute. Vocal cord paralysis occurs in 1 (0.07%) of 1,500 general surgery patients and on the left side in 70% of cases. It is associated with surgery/anesthesia time (two-fold, 3-6 hours; 15-fold, over 6 hours), age (three-fold, over 50 years), and diabetes mellitus or hypertension (two-fold). Symptoms resolve in 2-3 months. In adult cardiovascular surgery, vocal cord paralysis occurs in 1 (0.7-2%) of 50-100 cardiac surgery patients and 1 (8.6-32%) of 3-10 thoracic aortic surgery patients. In pediatric cardiac surgery, vocal cord paralysis occurs in 1 (0.1-0.5%) of 200-1,000 patients. We classified the severity of vocal cord paralysis as I, severe hoarseness; II, aspiration or dysphagia; and III, bilateral vocal cord paralysis, aspiration pneumonia, or the need for tracheal re-intubation or tracheotomy. We discuss the importance of informed consent for the patient and family.

Sleep paralysis typically occurs as individuals awaken from rapid eye movement sleep before motor paralysis wanes. Many episodes are accompanied by tactile and visual hallucinations, often of threatening intruders in the bedroom. Pendergrast [Victims of Memory: Incest Accusations and Shattered Lives, HarperCollins, London, 1996] proposed that individuals who report repressed or recovered memories of childhood sexual abuse (CSA) may misinterpret episodes of sleep paralysis as reemerging fragments of dissociated ("repressed") memories of CSA. To investigate this issue, we administered a sleep paralysis questionnaire to people reporting either repressed (n = 18), recovered (n = 14), or continuous (n = 36) memories of CSA, or to a control group reporting no history of CSA (n = 16). The prevalence of sleep paralysis was: repressed memory group (44%), recovered memory group (43%), continuous memory group (47%), and control group (13%). Among the six individuals in the recovered memory group who had experienced sleep paralysis, one interpreted it as related to sexual abuse (i.e., a rate of 17%). All other participants who had reported sleep paralysis embraced other interpretations (e.g., saw a ghost). Dissociation and depressive symptoms were more common among those who had experienced sleep paralysis than among those who denied having experienced it.

To review the aetiology and treatment of laryngeal paralysis diagnosed at our hospital and to describe the available therapeutic options. Retrospective review of medical records of 108 patients diagnosed with unilateral and bilateral vocal fold paralysis between 2000 and 2012, identifying the cause of paralysis and its treatment. Of the 108 cases analysed, 70% had unilateral vocal fold immobility and 30% bilateral immobility. The most frequent aetiology in both cases was trauma (represented mainly by surgical injury), followed by tumours in unilateral paralysis and medical causes in bilateral paralysis. Half of the patients with unilateral paralysis (38) were treated surgically, with medialization thyroplasty. In bilateral vocal fold immobility, the treatment consisted of tracheostomy in patients with threatened airway (40%). We planned to widen the air passage in 9 patients (27%), performing cordectomy in most of them. The aetiology observed in our patients is similar to that described in the literature. In cases of unilateral vocal fold paralysis, we believe thyroplasty is the procedure of choice. In bilateral paralysis, it is possible to perform cordectomy in selected patients once the airway has been secured.

Motor complications after herpes zoster are not uncommon. There have been reports of muscular paralysis following herpes zoster. The association between diaphragmatic paralysis and zoster was first reported in 1949 by Halpern. The case presented below showed diaphragmatic involvement following herpes zoster in a HIV-tuberculosis coinfected patient.

Aceclofenac has been shown to have potent analgesic and anti-inflammatory activities similar to indomethacin and diclofenac, and due to its preferential Cox-2 blockade, it has a better safety than conventional Non steroidal anti-inflammatory drug (NSAIDs) with respect to adverse effect on gastrointestinal and cardiovascular systems. Aceclofenac is superior from other NSAIDs as it has selectivity for Cox-2, a beneficial Cox inhibitor is well tolerated, has better Gastrointestinal (GI) tolerability and improved cardiovascular safety when compared with other selective Cox-2 inhibitor. To provide the patient with the most convenient mode of administration, there is need to develop a fast-disintegrating dosage form, particularly one that disintegrates and dissolves/disperses in saliva and can be administered without water, anywhere, any time. Such tablets are also called as "melt in mouth tablet." Direct compression, freeze drying, sublimation, spray drying, tablet molding, disintegrant addition, and use of sugar-based excipients are technologies available for mouth-dissolving tablet. Mouth-dissolving tablets of aceclofenac were prepared with two different techniques, wet granulation and direct compression, in which different formulations were prepared with varying concentration of excipients. These tablets were evaluated for their friability, hardness, wetting time, and disintegration time; the drug release profile was studied in buffer Phosphate buffered Saline (PBS) pH 7.4. Direct compression batch C3 gave far better dissolution than the wet granulation Batch F2, which released only 75.37% drug, and C3, which released 89.69% drug in 90 minutes.

A mouth aspirator with a bent glass tip was designed for adult mosquito collection and transportation. This aspirator has been utilized for mosquito laboratory and operational research in New Jersey for >60 years. We provide schematics and instruction for construction of this inexpensive and simple mouth aspirator, which offers improved maneuverability of handling adult mosquitoes from rearing cages in the laboratory and field application cages.
Frogs and toads mostly call with their mouths shut, unlike many other vertebrates. Sound is generated when air crosses the larynx, but there is no direct airflow to the external environment and radiation occurs at the skin. This study directly compares the acoustic output obtained from euthanized frogs with the mouth open against the output obtained with the mouth closed during activation of the larynx by airflow. With the mouth closed, the vocal sac was inflated and the acoustic energy was concentrated in the same harmonics as in the advertisement call, whereas with the mouth open, energy was spread in a wide range of harmonics. The acoustic output at the dominant frequency was more intense with the mouth closed than with the mouth open. More sound was radiated through the vocal sac and head than through the rest of the body. The spectral differences between open and closed mouth treatments matched the differences observed between natural advertisement calls, produced with the mouth closed, and distress calls, produced with the mouth open. By calling with the mouth closed, treefrogs can potentially produce advertisement calls with the energy concentrated in a narrower frequency range than with the mouth open.
