NEUROPSYCHOLOGICAL REMEDIATION OF HYPERACTIVE CHILDREN
Agarwal, Neena; Rao, Shobini L.
1997-01-01
Hyperkinesis is associated with deficits of attention (poor allocation of attention resources, susceptibility to interference and perseveration); vigilance and perceptual sensitivity. Three boys aged 7-8 years with simple hyperkinesis were given cognitive tasks to improve the above functions in daily one hour sessions for a month. The children improved significantly in the above functions and behaviour. Three other children aged 5-8 years with simple hyperkinesis who were on medication improved only slightly in their behaviour during this period. Behavioural intervention and parental counselling were additional inputs to the children in both groups. Neuropsychological remediation combined with parental counselling and behavioural intervention shows promise in treating hyperactive children. PMID:21584098

Danilov, I. V.; Kudrayatseva, N. N.
1979-01-01
In hyperkinetic monkeys a response opposite to that of healthy monkeys was observed during rhythmic photostimulation (frequency 3, 9, 18, 20, and 25/sec), i.e., the hyperkinesis disappeared. The significance of rhythmic excitatory cycles for interconnections between different brain structures is discussed.

The association between hyperkinesis and breakdown of parenting in clinic populations
Foreman, D; Foreman, D; Minty, E
2005-01-01
Background: There is increasing recognition that child based, as well as parent based factors may be associated with children being excluded from their families. Despite the distress routinely observed among the parents of hyperactive children, there is little research on this in clinic populations. Aims: To examine removals from home in a typical secondary care population, where hyperkinesis was accurately diagnosed. Methods: A total of 201 cases were coded using mulitaxial ICD-10 criteria and Jarman indices derived from census data. Results: Hyperkinetic children were more than three times more likely to have suffered removal from home than children with other psychiatric diagnoses, independent of any psychosocial measure. Conclusion: Hyperkinesis is a specific risk factor for removal from home, which can operate in the absence of other psychosocial stressors. Screening children for hyperactivity is now simple, and the routine paediatric examination for children accommodated by the local authority gives an opportunity for early detection and treatment of hyperactivity in children at risk of family breakdown.

2016-08-01
The current study explored the influences of genetic and environmental factors on the mental health of twins between ages 6 and 16. A total of 41 monozygotic (MZ) twins and 35 dizygotic twins were recruited. The psychological attributes and environmental information of children were evaluated. A significant correlation was found between twins in the diagnostic categories of any psychiatric disorder and attention deficit/hyperactivity disorder (ADHD)/hyperkinesis based on the Strengths and Difficulties Questionnaire scale in MZ twins. Furthermore, fathers' authoritarian parenting style was positively correlated with the probability of any psychiatric disorders and oppositional/conduct disorders, whereas mothers' authoritative parenting style was negatively correlated with the probability of any psychiatric disorders and ADHD/hyperkinesis. The probability of emotional disorders was negatively correlated with scores on the Stressful Life Events Scale. These results collectively suggest that genetic and environmental elements, such as parental rearing style and stressful life events, may influence children's mental health.

The influence of NMDA and metabotropic neostriatal glutamate receptors blockade to avoidance conditioning (in shuttle box) and free locomotor behavior (in open field) in chronic experiments in rats were investigated. The glutamate receptor antagonists were injected bilateral into striatum separately and with the GABA-A receptor antagonist picrotoxin (2 microg), that produced in rats the impairment of avoidance conditioning and choreo-myoklonic hyperkinesis. The most effective in preventing of negative picrotoxin influence on behavior was 5-type metabotropic glutamate receptors antagonist MTEP (3 microg). Separately injected MTEP did not influence on avoidance conditioning and free locomotor behavior. Unlike that, 1-type metabotropic glutamate receptors antagonist EMQMCM (3 microg) impaired normal locomotor behavior and did not prevent the picrotoxin effects. The NMDA glutamate receptors MK 801 (disocilpin--1 and 5 microg) impaired the picrotoxin-induced hyperkinesis, but did not to prevent the negative effects on avoidance conditioning; separately injected MK 801 reduced free locomotor activity. Based on location of investigated receptor types in neostriatal neurons membranes, we proposed that the most effective influence on 5-type metabotropic glutamate receptors is associated with their involvement in "indirect" efferent pathway, suffered in hyperkinetic extrapyramidal motor dysfunction--Huntington's chorea in human.

Paroxysmal anal hyperkinesis: a characteristic feature of proctalgia fugax.
Rao, S S; Hatfield, R A
1996-10-01
Proctalgia fugax is a common problem, yet its pathophysiology is poorly understood. The objective was to characterise colorectal disturbances in a paraplegic patient with a 10 year history of proctalgia fugax that began two years after an attack of transverse myelitis. Standard anorectal manometry and prolonged 33 hour ambulatory colonic manometry at six sites in the colon were performed together with myoelectrical recording of the anus. Provocative tests designed to simulate psychological and physical stress and two types of meals were included. Anorectal manometry showed normal internal sphincter tone and normal rectoanal inhibitory reflex but an inability to squeeze or to bear down or to expel a simulated stool. Rectal sensation (up to 360 ml inflation) was absent. Pudendal nerve latency was prolonged (4.5 ms (normal < 2.2 ms). During colonic manometry, the patient reported 27 episodes of pain, of which 23 (85%) were associated with bursts (1-60 min) of a high amplitude (0.5 to > 3.2 mv), high frequency (5-50/min) anal myoelectrical activity, particularly after stress tests, meals, and at night. The myoelectrical disturbance only occurred with proctalgia. Intermittently, 16 bursts of 3 cycles/ min phasic rectal contractions were seen, but only six were associated with proctalgia. Colonic motility was reduced compared with normal subjects. The temporal association between a high amplitude, high frequency myoelectrical activity of the anal sphincter, and the occurrence of proctalgia suggests that paroxysmal hyperkinesis of the anus may cause proctalgia fugax.

Botulinum toxin in the management of facial paralysis.
Cabin, Jonathan A; Massry, Guy G; Azizzadeh, Babak
2015-08-01
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.

The group of hallucinogenic mushrooms (species of the genera Conocybe, Gymnopilus, Panaeolus, Pluteus, Psilocybe, and Stropharia) is psilocybin-containing mushrooms. These "magic", psychoactive fungi have the serotonergic hallucinogen psilocybin. Toxicity of these mushrooms is substantial because of the popularity of hallucinogens. Psilocybin and its active metabolite psilocin are similar to lysergic acid diethylamide. These hallucinogens affect the central nervous system rapidly (within 0.5-1 hour after ingestion), producing ataxia, hyperkinesis, and hallucinations. In this review article there are discussed about history of use of hallucinogenic mushrooms and epidemiology; pharmacology, pharmacodynamics, somatic effects and pharmacokinetics of psilocybin, the clinical effects of psilocybin and psilocin, signs and symptoms of ingestion of hallucinogenic mushrooms, treatment and prognosis.

Two recent studies described a temporal association between a high-amplitude and high-frequency myoelectrical activity of the anal sphincter and the occurrence of proctalgia, which suggest that paroxysmal hyperkinesis of the anus may cause proctalgia fugax. We describe a single case of proctalgia fugax responding to anal sphincter injection of Clostridium botulinum type A toxin. The presumed aetiology of proctalgia fugax is discussed and the possible mechanism of action of botulinum toxin (BTX) in this condition is outlined. Botulinum A toxin seems to be a promising treatment for patients with proctalgia fugax, and further trials appear to be worthwhile for this condition, which has been described as incurable.

[Identification and evaluation of the neuroleptic activity of phenotropil].
Akhapkina, V I; Akhapkin, R V
2013-01-01
The neuroleptic (antipsychotic) activity of phenotropil was studied in an experimental animal model. Phenotropil had a marked neuroleptic activity in models of positive (apomorphine-induced verticalization test) and negative (5-HTP-induced hyperkinesis test) symptoms of psychoses as well as in the m-cholinergic pathway hyperactivation (arecoline-induced tremor test). The compound markedly antagonized haloperidol catalepsy. Used in a single dose or as a course treatment, phenotropil did not provoke aggression nor intensify it. In contrast to typical and atypical antipsychotics, phenotropil had no sedative action and other adverse effects. It exhibited a positive effect on exploratory behavior and motor activity, had anxiolytic and antidepressant action.

Almost 60% of food additives are colorings, flavorings and other appearance enhancers. Growth of the world's population and growth in demand for food represent the greatest technological challenge of our era. Consequently, usage of substances which preserve the quality and diminish spoilage of food is of prime importance. Nevertheless, the consumer fears that the cumulative effect of additives can lead to cancer, hyperkinesis or other disorders. Given the widespread use of additives, their impact on the health of populations is difficult to study even if certain observed differences between countries are attributed to their diet. Additives introduced during the last few years have satisfied rigorous testing—to which the majority of natural products are not submitted. In contrast, overeating, inactivity, excess saturated fat, alcohol and cigarets are still prevalent, even though the health risks they represent are clearly established. Seeing that the doctor is an authority on health matters, his or her contribution in dispensing information on nutrition and health is important in the battle against fear without scientific proof.

2000-07-01
This study examined the behavioral problems in Chinese children of divorced parents. A total of 58 children of divorce and 116 gender-, age-, and school class-matched controls were ascertained from a general population sample of children aged 6 through 15 years. Parents completed the Child Behavior Checklist (CBCL), and teachers completed the Teacher's Report Form (TRF) and Conners Hyperkinesis Index. Parent-reported problem scores on the CBCL total scale and each subscale, and prevalence of all CBCL syndromes except for Somatic Complaints, were significantly higher in children of divorce than in controls. Teacher-reported problem scores on the TRF total scale and Social and Attention Problems and prevalence of Attention Problems were significantly different for the 2 groups of children. Social competence was rated significantly lower in children of divorce than in controls. Discriminant function analysis showed that behavioral problems in children of divorce were characterized by aggressive behavior, withdrawal, and social problems. The findings emanating from China provide the first evidence of the link between parental divorce and children's psychopathology and clarify the psychopathological dimensions in Chinese children of divorced parents.

A 10-month-old Weimaraner bitch was presented at the practice exhibiting agitation, hyperactivity, inability to learn and attention deficit. The diagnostic findings were excessive, long-lasting acoustic and locomotory activity with unexpected inappropriate reactions. Hematological and biochemical blood analyses did not demonstrate abnormal findings. The first attempts at behavioral therapy and fluoxetine application were unsatisfactory. Therefore, a test was conducted with medication for central nervous system stimulation to confirm a diagnosis of hyperkinesis. Following the diagnosis of attention deficit hyperactivity disorder, the therapy was continued with behavioral modifications, with special consideration of rehabituation and resocialization as well as the use of methylphenidate. During the course of the therapy the bitch developed hyperactivity again when on heat. After changing the dosage of methylphenidate and additionally using dog appeasing pheromone, the behavior of the bitch became normal after 8 days. Two months later endoscopic ovarioectomy was performed. Twelve months after the initial use of methylphenidate the medication could be discontinued completely and the dog's behavior was normal. The methylphenidate dosage used during this therapy was much higher than recommended in the literature.

Factors associated with bruxism in children with developmental disabilities.
Souza, Valeska Aparecida Fernandes; Abreu, Mauro Henrique Nogueira Guimarães; Resende, Vera Lúcia Silva; Castilho, Lia Silva
2015-01-01
The aim of the present study was to investigate factors associated with bruxism in children aged from 1 to 13 years with developmental disabilities. A total of 389 dental records were examined. The bruxism analyzed was determined based on parental reports. The following variables were also analyzed: gender, age, International Code of Diseases (ICD), mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, gingival status, reports of xerostomia, hyperkinesis, pacifier use, thumb sucking and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without bruxism. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Females had a 0.44-fold (95%CI: 0.25 to 0.78) greater chance of exhibiting bruxism than males. Individuals with gastroesophageal reflux had a 2.28-fold (95%CI: 1.03 to 5.02) greater chance of exhibiting bruxism. Individuals with reported involuntary movements had a 2.24-fold (95%CI: 1.19 to 4.24) greater chance of exhibiting bruxism than those without such movements. Exhibiting involuntary movements, the male gender and gastroesophageal reflux are factors associated with bruxism in children with developmental disabilities.

We divided 19 patients with essential tremor into two subtypes according to clinical characteristics of the tremor. Ten patients had pure postural tremor distributed in the hand(s), head, and face (group A). Nine patients had tremor extending to the voice or leg(s), associated with resting tremor and/or hyperkinesie volitionnelle of the hand(s) (group B). Their ages, the age of onset, and the duration of illness were not different between the two groups. Electrophysiologically, the tremor of group A patients had higher frequencies than that of group B patients, and had synchronized activities for antagonistic muscles. Four of group B patients had reciprocal antagonistic activities of the tremor. Inactive phase of tremor induced by an electrically-evoked muscle twitch was invariably within the range of the physiological silent period for group A patients, and prolonged beyond the range for four of group B patients. Pharmacologically, 78% of group A patients responded well to beta-blocker, which was effective for 25% of group B patients. Sixty per cent of beta-blocker-resistant group B patients responded well to phenobarbital. In conclusion, a peripheral mechanism, presumably beta-adrenergic drive, is important for the tremor in group A patients, while central pathogenic mechanisms are more important for the tremor of group B patients.

To investigate factors associated with anterior open bite in individuals aged from 2 to 33 years with developmental disabilities. This is a cross-sectional study. A total of 271 dental records were examined. The anterior open bite analyzed was determined based on clinic exam. These variables were also analyzed: gender, age, education level of mother, International Code of Diseases (ICD), mouth breathing, use of anticonvulsant drugs, hyperkinesis, pacifier use, thumb sucking, seizure, and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without anterior open bite. Variables with a p-value of < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Mouth breathers had a 2.60-fold (95% CI: 1.35-5.01) greater chance of exhibiting anterior open bite than nasal breathers. Pacifier users are more likely to have an anterior open bite (3.32-fold, 95% CI: 1.62-6.77). Individuals with reported involuntary movements had a 2.66-fold (95% CI: 1.26-5.63) greater chance of exhibiting anterior open bite. Users of anticonvulsants drugs had a 3.05 (95% CI: 1.57-5.92) greater chance of showing anterior open bite. Involuntary movements, mouth breathing, using anticonvulsant drugs, and using pacifier are factors associated with anterior open bite in patients with developmental disabilities. © 2017 Special Care Dentistry Association and Wiley Periodicals, Inc.

Botulinum toxin treatment for facial palsy: A systematic review.
Cooper, Lilli; Lui, Michael; Nduka, Charles
2017-06-01
Facial palsy may be complicated by ipsilateral synkinesis or contralateral hyperkinesis. Botulinum toxin is increasingly used in the management of facial palsy; however, the optimum dose, treatment interval, adjunct therapy and performance as compared with alternative treatments have not been well established. This study aimed to systematically review the evidence for the use of botulinum toxin in facial palsy. The Cochrane central register of controlled trials (CENTRAL), MEDLINE(R) (1946 to September 2015) and Embase Classic + Embase (1947 to September 2015) were searched for randomised studies using botulinum toxin in facial palsy. Forty-seven studies were identified, and three included. Their physical and patient-reported outcomes are described, and observations and cautions are discussed. Facial asymmetry has a strong correlation to subjective domains such as impairment in social interaction and perception of self-image and appearance. Botulinum toxin injections represent a minimally invasive technique that is helpful in restoring facial symmetry at rest and during movement in chronic, and potentially acute, facial palsy. Botulinum toxin in combination with physical therapy may be particularly helpful. Currently, there is a paucity of data; areas for further research are suggested. A strong body of evidence may allow botulinum toxin treatment to be nationally standardised and recommended in the management of facial palsy.

The red tide toxin, brevetoxin, induces embryo toxicity and developmental abnormalities.
Kimm-Brinson, K L; Ramsdell, J S
2001-01-01
Brevetoxins are lipophilic polyether toxins produced by the red tide dinoflagellate Gymnodinium breve, and their neurotoxic effects on adult animals have been documented. In this study, we characterized adverse developmental effects of brevetoxin-1 (PbTx-1) using an exposure paradigm that parallels the maternal oocyte transfer of toxin. Medaka fish (Oryzias latipes) embryos were exposed to PbTx-1 via microinjection of toxin reconstituted in a triolein oil droplet. Embryos microinjected with doses of 0.1-8.0 ng/egg (ppm) of brevetoxin-1 exhibited pronounced muscular activity (hyperkinesis) after embryonic day 4. Upon hatching, morphologic abnormalities were commonly found in embryos at the following lowest adverse effect levels: 1.0-3.0 ppm, lateral curvature of the spinal column; 3.1-3.4 ppm, herniation of brain meninges through defects in the skull; and 3.4-4.0 ppm, malpositioned eye. Hatching abnormalities were also commonly observed at brevetoxin doses of 2.0 ppm and higher with head-first, as opposed to the normal tail-first, hatching, and doses > 4.1 ng/egg produced embryos that developed but failed to hatch. Given the similarity of developmental processes found between higher and lower vertebrates, teratogenic effects of brevetoxins have the potential to occur among different phylogenetic classes. The observation of developmental abnormalities after PbTx-1 exposure identifies a new spectrum of adverse effects that may be expected to occur following exposure to G. breve red tide events.

While standardized methods are established to examine the pathway from motorcortex to the peripheral nerve in patients with facial palsy, a reliable method to evaluate the facial muscles in patients with long-term palsy for therapy planning is lacking. A 3D ultrasonographic (US) acquisition system driven by a motorized linear mover combined with conventional US probe was used to acquire 3D data sets of several facial muscles on both sides of the face in a healthy subject and seven patients with different types of unilateral degenerative facial nerve lesions. The US results were correlated to the duration of palsy and the electromyography results. Consistent 3D US based volumetry through bilateral comparison was feasible for parts of the frontalis muscle, orbicularis oculi muscle, depressor anguli oris muscle, depressor labii inferioris muscle, and mentalis muscle. With the exception of the frontal muscle, the facial muscles volumes were much smaller on the palsy side (minimum: 3% for the depressor labii inferior muscle) than on the healthy side in patients with severe facial nerve lesion. In contrast, the frontal muscles did not show a side difference. In the two patients with defective healing after spontaneous regeneration a decrease in muscle volume was not seen. Synkinesis and hyperkinesis was even more correlated to muscle hypertrophy on the palsy compared with the healthy side. 3D ultrasonography seems to be a promising tool for regional and quantitative evaluation of facial muscles in patients with facial palsy receiving a facial reconstructive surgery or conservative treatment.

To comprehensively study the course of gastric ulcer disease (GUD) and duodenal ulcer disease (DUD) concurrent with chronic duodenal insufficiency (CDI). Ulcer disease (UD) was verified on the basis of the results of clinical and fibrogastroduodenoscopic examinations. The data of contrast duodenography and cavitary manometry were used to identify CDI. Gastroduodenal motor activity was investigated using the peripheral electrogastrograph EGG-4M. The results of pH measurements were employed to assess the state of gastric acid secretion and duodenal pH values. A comprehensive examination was made in 106 patients with UD concurrent with CDI (a study group) and 30 UD patients without CDI (a comparison group). Epigastric pain was noted in the patients with GUD in the study and comparison groups (91.5 and 84.6%, respectively), but the pain was mainly aching in the patients with concomitant CDI and more intense (77.8%) in those without this condition. In the study group, heartburn was more common in patients with GUD and DUD (75.3 and 71.4%, respectively) than in those with UD in the comparison group (28.5 and 37.5%, respectively). Helicobacter pylori tests were positive in 23.8% of the patients in the study group and in 57.2% in the comparison group. Electrogastrography indicated that the patients with GUD and CDI had bradygastria and hypokinesis on an empty stomach; the electrical activity was reduced after eating. In the comparison group, tachygastria and hyperkinesis were detected on an empty stomach; these postprandial indicators were elevated. H. pylori tests were positive in 34.7% of the patients with DUD and CDI and in 63.6% of those with DUD without CDI. The postprandial electrical activity increased in patients with DUD and decreased in the comparison group. The specific features of changes in gastric and duodenal pH values in GUD and DUD concurrent with CDI in comparison with the isolated course of UD. The immediate and long-term follow-ups show that GUD and DUD concurrent with CDI run a more persistent course; the time of ulcer healing increases and the periods of remission decrease.

Contralateral botulinum toxin injection to improve facial asymmetry after acute facial paralysis.

The application of botulinum toxin to the healthy side of the face in patients with long-standing facial paralysis has been shown to be a minimally invasive technique that improves facial symmetry at rest and during facial motion, but our experience using botulinum toxin therapy for facial sequelae prompted the idea that botulinum toxin might be useful in acute cases of facial paralysis, leading to improve facial asymmetry. In cases in which medical or surgical treatment options are limited because of existing medical problems or advanced age, most patients with acute facial palsy are advised to await spontaneous recovery or are informed that no effective intervention exists. The purpose of this study was to evaluate the effect of botulinum toxin treatment for facial asymmetry in 18 patients after acute facial palsy who could not be optimally treated by medical or surgical management because of severe medical or other problems. From 2009 to 2011, nine patients with Bell's palsy, 5 with herpes zoster oticus and 4 with traumatic facial palsy (10 men and 8 women; age range, 22-82 yr; mean, 50.8 yr) participated in this study. Botulinum toxin A (Botox; Allergan Incorporated, Irvine, CA, USA) was injected using a tuberculin syringe with a 27-gauge needle. The amount injected per site varied from 2.5 to 3 U, and the total dose used per patient was 32 to 68 U (mean, 47.5 +/- 8.4 U). After administration of a single dose of botulinum toxin A on the nonparalyzed side of 18 patients with acute facial paralysis, marked relief of facial asymmetry was observed in 8 patients within 1 month of injection. Decreased facial asymmetry and strengthened facial function on the paralyzed side led to an increased HB and SB grade within 6 months after injection. Use of botulinum toxin after acute facial palsy cases is of great value. Such therapy decreases the relative hyperkinesis contralateral to the paralysis, leading to greater symmetric function. Especially in patients with medical problems that limit the medical or surgical treatment options, botulinum toxin therapy represents a useful alternative. (C) 2013 Otology & Neurotology, Inc.

Reports in clinical literature about persistent terminal extrapyramidal hyperkinesis in neuroleptic long-term treated patients and speculation about demential brain decomposition in such cases give rise to support irreversible psychopharmacotoxical brain damage. Histopathological and animal experimental results in this question given up to this day are not in agreement with each other. Therefore an own chlorpromazine long-term experiment in rats is reported with special regard to biometric-statistical results. Experiments were performed in 36 adult albino rats of either sex, weighing 300-400 g, fed by a standard diet, receiving food and water ad libitum. The animals were divided into 3 groups of 12 animals accidentally. Group I received 15 mg/kg/die chlorpromazine per os by means of a throat probe, group II 10 mg/kg/die, group III was left untreated (controls). The experiment was carried out for 6 months, the animals were killed by perfusion of Bouin's solution 6-8 weeks after interruption of chlorpromazine application. 8 mum paraffin sections were stained by kresylviolet. After histological examination the material was investigated statistically. In the ncl. N. XII, ncl. N. VII, ncl, orig et term. N.V., ncl. cochlearis ant., ncl. vestibularis princeps, Oliva sup., and ncl. dentatus the glia/neurons ratio was stated by counting 200 cells, and in the formation reticularis 400 cells in each animal. The calculated differences in the glia/neurons ratio between the groups were evaluated for statistical significance by the chi2-test. In the ncl. dentatus, oliva sup., ncl, cochlearis ventr., and ncl, vestibularis glia cells and neurons were counted in a plane of 1.2 mm2, in the formatio reticularis and in homologuous parts of cerebellar stratum moleculare in a plane of 2.4 mm2. The differences between the mean values of the groups were verified for statistical significance by means of the t-test. In histological examination only 50% of the animals of group I showed a slight loss of neurons and increase of glia cells. Statistically however, significant increase of glia cells was found in the glia/neurons ratio all over the investigated area (rhombencephalic brain stem and cerebellum) and for the ncl. dentatus, the oliva sup., and the ncl. cochlearis ventr. especially (table 1, fig.3). This change in the glia/neurons ratio is caused by a tendency for decreasing of neurons and increasing of glia cells, too (table 2). In the nucleus dentatus the loss of neurons was found to be of high significance. These changes are supposed to be due to chlorpromazine action, and in this manner the experimental results speak for an irreversible psychopharmacotoxical brain damage.

In recent years there has been an increasing number of cases of cancer, including cancer of the larynx. The choice of treatment should be primarily dictated by the complete elimination of cancer, but from the point of view of the patient, an important factor to keep in mind, is the quality of the voice that will be created at the end of the therapeutic process. The aim of this study was to evaluate the voice quality of patients after partial surgery of the larynx with vocal fold reconstruction pedunculated sterno-thyroid muscle flap. The study included 30 men aged 53-72 years who were treated at the Clinic of Otorhinolaryngology Department of Medical-Dental Medical University of Warsaw on account of cancer of the larynx, qualified according to the TNM classification T1 or T2. The radical removal of cancer was associated with resection of one vocal fold, laryngeal pouches and ventricular fold. In 15 patients, included to the group I at the end of phase oncology surgery, a reconstruction of "vocal fold" pedunculated sterno-thyroid muscle flap were performed simultaneously. The group II consisted of 15 patients who underwent surgery that removed only the cancerous lesions. Impact assessments arising after surgery of voice disorders on quality of life were made using the self-test failure of the voice (Voice Handicap Index in the Pruszewicz modification). The nature of the created voice was studied using GRBAS scale. All patients performed the laryngostroboscope examination. With "IRIS" program, prepared by a team at Wrocław University of Technology, the voice was recorded, and then was subjected to acoustic analysis. In addition, noise level and the maximum phonation time was measured. The results indicate that the patients of group I gained a better voice confirming the values of objective acoustic analysis. The assessment made by the scale GRBAS patients who supplemented the resulting loss after tumour removal, with much less hoarseness of voice, did not have the hyperkinesis and there was no puff character. They had the better flow of voice and phonation time of vowels "a" was much longer. The assessment of quality of life of patients in group I made in a test of the VHI was higher than in group II. The laryngostroboscope examination confirmed a good phonatory occlusion and a nearly regular, healthy vocal fold vibration in patients who had received flap of muscle. Evaluation of the quality of voice after removing the tumor multiplicity in the glottis with simultaneous reconstruction "vocal fold" has confirmed that this is a very good surgical technique, which allows radically curing cancer for the simultaneous preservation of a good voice. The operation has limited indications for radiotherapy because of the desire to preserve the phonatory function of the larynx, and thus avoids the negative effects of radiation.

Objective: This study aimed to examine the factors influencing the requirement of a certificate of long-term care using a basic checklist and items listed in the Special Health Checkup. Method: This study included 7,820 individuals living in Uji city, who were selected from among 8,000 elderly individuals who, in 2008, underwent a specific health checkup (hereafter referred to as the 'specific health checkup for the old-old elderly individuals') for those aged 75 years and above. They answered questions from basic checklists at the time, and 180 individuals were excluded as they had already qualified for requiring the certificate of long-term care at the time of the checkup. The follow-up period extended from the day of the specific health checkup for the old-old elderly individuals to March 31, 2013. The data were analyzed using the certificate of needing long-term care as the response variable. The explanatory variables were the basic attributes, items listed in the specific health checkup for the old-old elderly individuals, interview sheets, and basic checklists. Cox proportional hazards regression analysis was conducted. Results: In total, 1,280 elderly individuals qualified for requiring the certificate of needing long-term care. The risk factors for the young-old elderly individuals aged 65 to 74 years were as follows: hepatic dysfunction (hazard ratio {HR}=1.69), the presence of subjective symptoms (HR=1.41), an above-normal abdominal circumference (HR=1.36), old age (HR=1.13), a reduced frequency of going out since the previous year (HR=1.87), the use of support for standing up after being seated on a chair (HR=1.86), no deposit or withdrawals made (HR=1.84), the anxiety of falling down (HR=1.50), an inability to climb stairs without holding a railing or wall (HR=1.49), as well as an increased difficulty in eating tough food items compared with 6 months prior (HR=1.44). The risk factors for the old-old elderly individuals were as follows: a positive reaction on proteinuria (HR=1.27), anemia (HR=1.18), old age (HR=1.10), inability to travel on a bus or train by themselves (HR=1.53), the inability to climb stairs without holding a railing or wall (HR=1.48), weight loss (HR=1.36), a reduced sense of appreciation of the activities they had previously participated in, over a span of 2 weeks (HR=1.30), the use of support for standing up after being seated on a chair (HR=1.23), and the anxiety of falling down (HR=1.20). Conclusion: The items listed in the specific medical checkup as well as the basic checklists were found to be risk factors for both the young-old elderly individuals and the old-old elderly individuals, indicating the need to utilize these lists for the prevention of nursing even in the late stages of life. Moreover, these results suggest the importance of screening elderly individuals suffering from hyperkinesis using the basic checklist and conducting preventive interventions in order to maintain and improve their physical functions.
