Inhibition of HIF-1α-AQP4 axis ameliorates brain edema and neurological functional deficits in a rat controlled cortical injury (CCI) model

Traumatic brain injury (TBI) is an important cause of death in young adults and children. Till now, the treatment of TBI in the short- and long-term complications is still a challenge. Our previous evidence implied aquaporin 4 (AQP4) and hypoxia inducible factor-1α (HIF-1α) might be potential targets for TBI. In this study, we explored the roles of AQP4 and HIF-1α on brain edema formation, neuronal damage and neurological functional deficits after TBI using the controlled cortical injury (CCI) model. The adult male Sprague Dawley rats were randomly divided into sham and TBI group, the latter group was further divided into neutralized-AQP4 antibody group, 2-methoxyestradiol (2-ME2) group, and their corresponding control, IgG and isotonic saline groups, respectively. Brain edema was examined by water content. Hippocampal neuronal injury was assessed by neuron loss and neuronal skeleton related protein expressions. Spatial learning and memory deficits were evaluated by Morris water maze test and memory-related proteins were detected by western blot. Our data showed that increased AQP4 protein level was closely correlated with severity of brain edema after TBI. Compared with that in the control group, both blockage of AQP4 with neutralized-AQP4 antibody and inhibition of HIF-1α with 2-ME2 for one-time treatment within 30-60 min post TBI significantly ameliorated brain edema on the 1st day post-TBI, and markedly alleviated hippocampal neuron loss and spatial learning and memory deficits on the 21st day post-TBI. In summary, our preliminary study revealed the short-term and long-term benefits of targeting HIF-1α-AQP4 axis after TBI, which may provide new clues for the selection of potential therapeutic targets for TBI in clinical practice.

Effects of TPH2 gene variation and childhood trauma on the clinical and circuit-level phenotype of functional movement disorders

BACKGROUND

Functional movement disorders (FMDs), part of the wide spectrum of functional neurological disorders (conversion disorders), are common and often associated with a poor prognosis. Nevertheless, little is known about their neurobiological underpinnings, particularly with regard to the contribution of genetic factors. Because FMD and stress-related disorders share a common core of biobehavioural manifestations, we investigated whether variants in stress-related genes also contributed, directly and interactively with childhood trauma, to the clinical and circuit-level phenotypes of FMD.

METHODS

Sixty-nine patients with a 'clinically defined' diagnosis of FMD were genotyped for 18 single-nucleotide polymorphisms (SNPs) from 14 candidate genes. FMD clinical characteristics, psychiatric comorbidity and symptomatology, and childhood trauma exposure were assessed. Resting-state functional connectivity data were obtained in a subgroup of 38 patients with FMD and 38 age-matched and sex-matched healthy controls. Amygdala-frontal connectivity was analysed using a whole-brain seed-based approach.

RESULTS

Among the SNPs analysed, a tryptophan hydroxylase 2 (TPH2) gene polymorphism-G703T-significantly predicted clinical and neurocircuitry manifestations of FMD. Relative to GG homozygotes, T carriers were characterised by earlier FMD age of onset and decreased connectivity between the right amygdala and the middle frontal gyrus. Furthermore, the TPH2 genotype showed a significant interaction with childhood trauma in predicting worse symptom severity.

CONCLUSIONS

This is, to our knowledge, the first study showing that the TPH2 genotype may modulate FMD both directly and interactively with childhood trauma. Because both this polymorphism and early-life stress alter serotonin levels, our findings support a potential molecular mechanism modulating FMD phenotype.

Neurologists' experiences of participating in the CODES study-A multicentre randomised controlled trial comparing cognitive behavioural therapy vs standardised medical care for dissociative seizures

PURPOSE

We investigated neurologists' experience of participating in the large CODES trial involving around 900 adults with dissociative seizures which subsequently evaluated the effectiveness of tailored cognitive behavioural therapy (CBT) plus standardised medical care versus standardised medical care alone in 368 patients with dissociative seizures.

METHOD

We asked all neurologists referring patients with dissociative seizures to the CODES study to complete a 43-item online survey. This examined neurologists' (i) demographics, (ii) knowledge of dissociative seizures before and after their involvement in the CODES trial, (iii) clinical practice before, during and since their involvement, and (iv) their experience of the CODES trial.

RESULTS

Forty-three (51%) neurologists completed the questionnaire. Only about half of neurologists could make referrals to psychological intervention specific for dissociative seizures before and after the trial. One-third of doctors reported having changed their referral practice following their involvement. The majority (>69%) agreed that patient satisfaction with different aspects of the trial was very high, and 83.7% thought that it was easy to recruit patients for the study. Over 90% agreed they would like the treatment pathway to continue. Respondents found different elements of the trial useful, in particular, the patient factsheet booklet (98%), diagnosis communication advice (93%) and the CBT package (93%).

CONCLUSIONS

Neurologists participating in CODES generally found it easy to recruit patients and perceived patient satisfaction as very high. However, 46.5% of neurologists could not offer psychotherapy once the trial had finished, suggesting that problems with lack of access to psychological treatment for dissociative seizures persist.

The role of emotion dysregulation in Conversion Disorder

INTRODUCTION

The role that emotion regulation plays in Conversion Disorders (CD) is not well known. This research deepens in this subject and describes the main differences between a group of conversion patients and a control group on different measures of emotion regulation and other clinical variables.

METHODS

A case-control study was conducted including 43 patients suffering from CD and 42 healthy controls. Both groups went thought two psychiatric interviews and fulfilled 6 questionnaires assessing depression, anxiety, alexithymia, emotion dysregulation, affect intensity, psychoform and somatoform dissociation.

RESULTS

Patients suffering from CD scored significantly higher on all the six questionnaires (p<0.001). Negative reactivity and negative intensity were also higher in patients (p<0.01), while cases and controls did not show any significant differences on positive affectivity and serenity. Anxiety, alexithymia and emotional dysregulation were the most relevant factors (OR=5.85/3.50/3.23 respectively). Anxiety and difficulties in emotion regulation were the most explicative variables for conversion in the regression analysis performed. Within the five factors assessing difficulties in emotion regulation, lack of emotional control and interference in goal directed behaviors were the most relevant. Positive and negative conversion where correlated to different emotional impairments.

CONCLUSIONS

People suffering from CD show several emotional impairments when compared to healthy controls. Emotion dysregulation can be considered a relevant aspect in CD. The existence of specific emotional patterns for different conversion manifestations is suspected.

[A manner of voicing, the mass hysteria]

INTRODUCTION

Mass hysteria is defined as the epidemic occurrence of a succession of physical symptoms without organic disorder or identifiable illness agents. The hysteria epidemic has been described since the Middle Ages, reported in different cultures and religions and affects different populations throughout the world. Few studies on the subject have been under takenin Madagascar. We aim at describing in this study the clinical and therapeutic aspects of a mass hysteria that has occurred in the South of Madagascar.

METHODOLOGY

The study is retrospective and prospective at the same time. It concerns the victims of a mass hysteria that had occurred in a village (Ikalahazo) in the South of Madagascar,from the 6th of April 2009 to the 7th of May 2009. Patients exhibiting clinical symptoms ofconversive behavior and having undergone an assessment in hospital surroundings represent the object of this study. During the study period, 27 cases of young women were reported, 22 ofthem were sent to the University Hospital Center of Fianarantsoa (UHCF), a referring center o fthe region, for a thorough clinical examination. Demographic data, the clinical aspects and thecare and treatment provided are the studied parameters.

RESULT

During a land ownership dissension that drags on endlessly in Ikalahazo village, exclusively 27 young women, between 8 and 21 years old, presented atypical symptoms, strangedisorders. A first case appeared on the 6th of April 2009, that is to say a month before alarge manifestation of the crisis. A similar case was observed two years ago, but it was an isolated case. The symptoms, primarily with motive manifestation, extended rapidly but remainedhowever limited, susceptible to the "Mpiandry" (literally "shepherds") advice. As the villagers believed that spiteful spirits were at the origin of the deeds, they appealed to the latter. Facing the symptoms persistence, the Neuropsychiatry Unit employees of the CHUF were sent to the village on the 6th of May 2009. The intense adhesion of villagers to a belief in satanic misdeedscomplicated their somatic assessment, the results of which showed no distinctive features. At the end of the land dissension proceedings that was resolved in favor of the villagers, and after the isolation of the "madwomen" in the Mpiandry’s camp, no more pathological cases related to the above occurrence were reported.

CONCLUSION

A mass hysteria diagnosis is retained. It is favored and kept up by local dissensions,by the villagers' belief and its large media casting, thanks to the shepherds' presence. It mingles culture, tradition and modern psychiatry. Therefore, care and treatment of the disorder to be appropriate and optimal require the cooperation between these three spheres.

Globus hystericus

Globus hystericus (GH) is a subjective feeling of a lump or foreign body in the throat thought to involve psychogenic factors, a form of somatisation disorder. The more modern terms, globus sensation or globus pharyngeus, reflect recognition of one or more possible contributing anatomico-physiological factors, such as gastro-oesophageal reflux disease (GORD) or pharyngeal inflammation.

[Before you diagnose a patient with a conversion disorder, perform a thorough general medical and neurological examination. Case study]

INTRODUCTION

Dissociative and conversion disorders are classified together according to ICD-10 as states that are not confirmed by the presence of somatic diseases, which they suggest. According to the DSM-IV, both disorders are classified separately. Conversion disorders are a group of psychiatric disorders whose symptoms mimic the presence of malfunction or loss of motor or sensory function, whereas the nature and dynamics of the observed symptoms is not fully explained by the results of objective assessments and consultations, nor is the direct effect of a psychoactive substance. Impaired mental integration of different functions which normally interact simultaneously in the perception of reality and inner experience of the individual is found in dissociative disorders.

AIM

The article describes the case of 25-year old man, in whom after initial suspicion of myasthenia gravis and its exclusion, a diagnosis of conversion disorder was made on the basis of the clinical picture and treatment with an SSRI antidepressant and individual psychotherapy were recommended. No improvement in mental and neurological status after six month therapy resulted in an in-depth diagnostics in a clinical setting and diagnosis of brain stem tumor (aastrocytoma fibrillare).

CONCLUSIONS

(a) Neuroimaging is a source of important clinical data and in many cases should constitute an inherent element of a psychiatric diagnosis. (b) Diagnosis of conversion (dissociative) disorders requires a precise differential diagnosis, excluding the somatic causes of observed neurological ailments. (c) A late diagnosis of neurological or somatic causes of symptoms which arouse a suspicion of conversion (dissociative) disorders may make a radical treatment impossible or may considerably aggravate the remote prognosis and quality of the patients' life.

Are your patient's medically unexplained symptoms really "all in her head"?

Even though the definitions in the third edition of the American Psychiatric Association's Diagnostic and Statistical Manual were supposed to be descriptions of clinical syndromes, the third and later editions of the DSM have included diagnostic categories for conversion disorder and various forms of somatization disorder, which represent an assertion of causality, not an observation of a clinical syndrome. Although these "disorders" represent etiologic diagnoses, the definitions provide no validated method for establishing causality in individual cases. Nor is there any validated methodology for making a presumptive diagnosis. Thus, it is impossible to make a diagnosis of conversion disorder or a somatization disorder without making an error in reasoning. These diagnostic categories should therefore be excluded from the DSM-V.

Role of sexual abuse in development of conversion disorder: case report

Described case report speaks in favour of the relation between childhood sexual abuse with the development of conversion disorder. Following Salmonella poisoning, adolescent, at the age of 16, develops series of severe somatic symptoms. Results of diagnostic procedures excluded organic foundation of the symptoms; diagnosis of conversion disorder is established. Soon, patient's problems stop abruptly and spontaneously, and the aetiology of the mental disorder remains unexplained. Six years later, adolescent reveals for the first time data about the childhood sexual abuse during the forensic evaluation (within the court process related to the request for compensation for the complications which occurred following the Salmonella infection). During the forensic evaluation, we had insight into the previous medical history, while an interview, psychological and psychiatric exploration was conducted with the examinee. Data about the sexual abuse retrospectively explain the dynamics of the development of conversion disorder. The described case indicates that sexual abuse of children and adolescents frequently remains unrecognized, which has sequels for treatment and prevention of subsequent consequences for mental health. It is important to emphasize the significance of examining history of abuse during the diagnostic of certain mental disorders. Forensic implications of the case have not been discussed in details for the needs of this report.

Sex distribution and psychiatric features of child and adolescent conversion disorder across 2 decades

BACKGROUND

Earlier research suggested female predominance in adult conversion disorder, and the strong association between conversion disorder and experiences of being abused is well known. However, the data for child and adolescent populations are limited. In Taiwan, the dramatic increase in child abuse may have some impact on the features of child and adolescent conversion disorder. This study aimed to compare the demographic characteristics, psychiatric comorbidity, and experiences of being abused in Taiwanese children and adolescents diagnosed with conversion disorder in psychiatric consultations across 2 decades.

METHODS

Retrospective and consecutive chart reviews were conducted for child and adolescent patients (< 20 years old) who were newly diagnosed with conversion disorder in psychiatric consultations at Taipei Veterans General Hospital from 1987 to 2006. The first group included patients who were diagnosed between 1987 and 1996 (the first decade), and the second group included patients who were diagnosed between 1997 and 2006 (the second decade).

RESULTS

A total of 42 patients diagnosed with conversion disorder were included in this study. Nineteen of the 42 subjects were diagnosed in the first decade (from 1987 to 1996), and 23 in the second decade (from 1997 to 2006). There existed among patients a tendency toward an increasing number of male subjects (p < 0.05), suffering more abuse (p < 0.05), and higher prevalence rates of depression and dysthymia comorbidity (p < 0.05) in the second decade compared to the first.

CONCLUSION

The sex distribution in conversion disorder might have significantly changed over the past 2 decades. There is an increasing need for screening and interventions for psychiatric comorbidity and experiences of being abused in children and adolescents with conversion disorder. Because of the small sample size of our study, further studies that include multiple study sites and a larger number of patients are needed before a firm conclusion can be drawn.

The study of allergic skin test in patients with globus pharyngeus: a preliminary report

BACKGROUND

Globus pharyngeus is the lump sensation in the throat associated with various conditions including somatoform disorder and gastroesophageal reflux disease. However, many patients with unrelated causes were found to respond to anti-allergic treatment.

OBJECTIVE

Determine the results of allergic skin test in globus pharyngeus patients who had unidentified causes.

MATERIAL AND METHOD

Fifty-four globus pharyngeus patients were enrolled and referred for complete physical examination, screening psychological status, videostroboscopy, and reflux finding score assessment. All patients including 38 controlled subjects underwent skin prick test and/or intradermal test. The globus patients who had positive test were recommended to have anti allergic treatment. Barium swallowing study, ambulatory double-probe pH monitoring, or plain film cervical spine was done in patients with negative skin tests and in non-response to medication.

RESULTS

There was statistically significant difference of positive skin test results between globus and the control group (77.8% vs. 28.6% OR = 13.12, p < 0.001). In positive skin test-globus group, globus symptom was improved in 64.3% after allergic treatment, which 85.2% had moderate and excellent improvement. In patients with negative skin test and non-response group show various conditions including gastroesophageal reflux disease (18.52%), abnormal esophageal manometry (40.74%), and myofascial pain syndrome (3.71%).

CONCLUSION

Due to high prevalence of positive skin test in globus pharyngeus patients, this symptom should be considered as one of the atypical allergic manifestations.

[Conversion disorder - review]

In modern medicine the term "functional symptoms" is usually used to refer to symptoms where an organic cause cannot be found. Studies have shown that up to half of all patients consulting their family physician and approximately one third of all those attending neurology outpatient clinics present with such symptoms. These patients commonly go between doctors, repeatedly undergo unnecessary tests, even surgery, and various drugs are tried with limited success. These problems tend to be prolonged and greatly reduce the quality of life for the patients involved. Both the DSM IV and ICD 10 classifications include a group for the so-called medically unexplained disorders. Among these disorders is conversion disorder where patients present with neurological symptoms, affecting motor or sensory function, but with no neurological explanation. Here we provide an overview of the current ideas on the aetiology, diagnosis, treatment and prognosis of conversion disorder.

[A case of conversion disorder (hysteria) after spinal anesthesia]

We report a case of conversion disorder after spinal anesthesia. A 16-year-old healthy woman underwent arthroscopic surgery under spinal anesthesia. She showed tremor all over and it did not stop. We sedated her with propofol during the operation. After the operation, her involuntary tremble continued. We consulted with a pediatrician who diagnosed her as conversion disorder. Magnetic resonance imaging and computed tomography were performed to rule out some pathological changes and abnormality in her head. As a result, Rathke cleft cyst was suspected but it could not explain this episode. We consider that her stress for the operation under spinal anesthesia caused this episode. In a case of a younger patient, it is necessary to consider mental support. And we need to suspect conversion disorder when we see tremor during operation under regional anesthesia.

Physical therapy management for conversion disorder: case series

PURPOSE

Patients with conversion disorder present with symptoms of sensory and motor dysfunction that are not explained by known physical disorders or pathophysiological mechanisms. Correct diagnosis and prompt, effective management of patients with this disorder is essential. Healthcare providers may be unaware of the important role of physical therapy in the management of patients with conversion disorder. While numerous reports have suggested the need for physical therapy management of this disorder, there is a lack of reports outlining specific physical therapy management principles or daily treatment progression. The purpose of this series of case reports is to provide an overview of conversion disorder and describe successful physical therapy management strategies used to treat three patients with movement impairment due to this disorder.

CASE DESCRIPTION

The patients were 18-, 20-, and 34-year-old women treated in a hospital inpatient rehabilitation setting. Behavioral modification and shaping techniques formed the basis for the physical therapy treatment approach. Abnormal movement patterns were ignored, and correct movement patterns were reinforced using feedback and praise. The patients advanced through a progressively more difficult therapy program based on treatment approaches used with analogous neurological conditions.

OUTCOMES

All three patients showed complete resolution of their symptoms and returned to independent mobility, independent living, and to work or school.

Conversion Locked-In Syndrome After Implantation of a Spinal Cord Stimulator

BACKGROUND

The locked-in syndrome is defined as quadriplegia and anarthria (loss of articulate speech) with the preservation of consciousness. It is typically caused by a lesion to the ventral pons. Conversion disorder is the deficit of voluntary motor or sensory function requiring an extensive work-up to exclude any organic cause.

METHODS AND RESULTS

After surgery for an implantation of a spinal cord stimulator, a 42-year-old woman presented with quadriplegia and lower facial diplegia, but was able to open and blink her eyes. We found no organic causes to explain her condition after appropriate radiological studies looking for intracranial or intraspinal causes, and reversal drugs were administered with no immediate effect. Over the course of several hours, the patient gradually recovered and was discharged the following day. A psychology consultation was obtained during her stay and she was found to meet the criteria for a conversion disorder to explain her condition.

CONCLUSIONS

Before considering a psychological cause, all organic factors should be excluded with proper tests and consultations, as conversion disorder is a diagnosis of exclusion. We report a patient who, after implantation of a spinal cord stimulator, manifested locked-in syndrome resulting from a conversion disorder.

Conversion disorder in Australian pediatric practice

OBJECTIVES

To describe the incidence and clinical features of children presenting to Australian child health specialists with conversion disorder.

METHOD

Active, national surveillance of conversion disorder in children younger than 16 years of age during 2002 and 2003.

RESULTS

A total of 194 children were reported on. The average age was 11.8 years; 23% were younger than 10 years of age. Presentations were complex, with 55% presenting with multiple conversion symptoms. The most common presentations were disturbance of voluntary motor function (64%), sensory symptoms (24%), pseudoseizure (23%), and respiratory problems (14%). Hospital admission was required for 70%, with an average stay of 10.2 days. Antecedent stressors were also reported in 62% and a history of mental health concerns in 42%, with 14% of children taking psychotropic medications for comorbid anxiety or depression. The incidence of conversion disorder in Australian specialist child health practice is estimated to be between 2.3 and 4.2/100,000.

CONCLUSIONS

Conversion disorder is associated with a significant burden for the child, family, and the health system. This study emphasizes the comorbidity with anxiety, depression, and symptoms of pain and fatigue. It also highlights the potential impact of "commonplace" stressors such as family conflict and children's loss of attachment figures.

Effect of deep brain subthalamic stimulation on camptocormia and postural abnormalities in idiopathic Parkinson's disease

Camptocormia has been described in patients with idiopathic Parkinson's disease (PD). We present a patient with young-onset PD in whom the disease progressed over 25 years to a crippling state with severe camptocormia and bent knees. The camptocormia along with other parkinsonian symptoms improved dramatically after bilateral subthalamic deep brain stimulation.

Prevalence, clinical spectrum and atypical symptoms of gastro-oesophageal reflux in Argentina: a nationwide population-based study

BACKGROUND

Population-based data on gastro-oesophageal reflux in Latin America are lacking.

AIM

To assess gastro-oesophageal reflux symptom prevalence, clinical spectrum and association with the atypical symptoms in our country.

METHODS

Gastro-oesophageal reflux self-report questionnaires validated at Mayo Clinic, USA, were submitted to a sample of 1000 residents (aged 18-80 years) from 17 representative geographical areas of Argentina. The samples were selected and stratified according to age, gender, geographical areas and size of town of residence provided by the Argentine Bureau of Statistics and Census.

RESULTS

The overall prevalence of any typical gastro-oesophageal reflux symptom experienced in the previous year was 61.2% (95% CI, 57.9-64.6), the prevalence of frequent gastro-oesophageal reflux symptoms was 23.0% (95% CI, 20.1-25.9) and the prevalence of gastro-oesophageal reflux disease was 11.9% (95% CI, 9.6-14.1). Frequent gastro-oesophageal reflux symptoms were associated with dysphagia (OR 2.12, 95% CI, 1.27-3.54, P < 0.01), globus (OR 2.22, 95% CI, 1.35-3.66, P < 0.01) and non-cardiac chest pain (OR 1.55, 95% CI, 1.04-2.31, P < 0.05).

CONCLUSIONS

In Argentina, typical symptoms of gastro-oesophageal reflux are highly prevalent at the national level, and frequent gastro-oesophageal reflux symptoms are significantly associated with dysphagia, globus and non-cardiac chest pain.

Cardiac angiography and conversion disorder

BACKGROUND

Somatoform disorders are disorders in which "psychic energy" is transferred to somatic symptoms secondary to stressors. The concept of somatoform disorders and their associations among patients with cardiac disease is a relatively unfamiliar area.

OBJECTIVE

The authors present a case that illustrates how conversion disorder, a specific type of somatoform disorder, may be associated with the psychologic stressor involved with cardiac angiography. The authors will discuss the literature concerning the identification and treatment of this disorder.

METHODS

The relevant literature in the area of conversion disorder and cardiac angiography was reviewed.

RESULTS

This report is the first documented case of a woman who developed conversion disorder after coronary catheterization. Using the case, a summary of diagnostic and treatment modalities used in this disorder is provided.

CONCLUSIONS

The case highlights how conversion disorder can occur as a sequelae of coronary catheterization. The principles involved in the diagnosis and treatment of conversion disorder were successful in managing this patient. It is hoped that the case can aid cardiologists in becoming cognizant of this uncommon psychiatric disorder.

Globus hystericus: a brief review

Globus hystericus, a form of conversion disorder, is characterized by an uncomfortable sensation of a mass in the esophagus or airway. Evaluation proves no mass exists. Anxiety or psychological conflict is judged to be significantly related to the onset and progression of the sensation. The sensation may lead to difficulty swallowing or breathing and may become severe or life threatening. The disorder is poorly studied and understood. The differential diagnosis is vast. Management of the disorder is similar to that suggested for other conversion disorders. This article reviews the current literature about diagnosis, etiology, treatment, and prognosis of globus hystericus.

[Sociodemographic and clinical characteristics of patients with conversion disorder]

OBJECTIVE

To determine the sociodemographic, and clinical characteristics, and comorbid diagnosis of patients with conversion disorder, and also to evaluate the relationship between the duration of conversion and comorbid diagnosis and personality factors.

METHOD

Seventy-two patients who were diagnosed with conversion disorder according to DSM-IV criteria, were included in this study. The Hacettepe Personality Inventor, was administered to all patients, and they were divided into two groups. The first group had conversion symptoms for four years (Group 1), while the other group had conversion symptoms more than four years (Group 2).

RESULTS

Sixty-three of patients were female, 9 were males. The average onset age of the disorder was 25.9+/-7.5. Seventy patients (97,2%) had received a maximum of 11 years of education. 40.3% of patients sought treatment because of seizures or convulsions, 40,3% because of sensory symptoms or deficits, 5% because of motor symptoms or deficits, and 12,6% because of mixed presentations. The mean duration of complaints was 4.2+/-1.4 years (min= 1, max= 20). 59.7% of the patients had prominent stress before the onset of the conversion symptoms. There were 12 (28.6%) comorbid psychiatric disorders in Group 1, and 17 (56,7%) in Group 2. Although the mean neurotic trend scores in Group 2 (6.1+/-4.1) were higher than Group 1 (3.1+/-3) (p=.03). The mean emotional resolution scores were lower in Group 2 (4.2+/-3.5) than in Group 1 (7.1+/-3.3) (P=.03).

CONCLUSION

Conversion disorder tends to start in early adulthood, and usually follows a stress factor. As the duration of the disorder increases, comorbid psychopathologies, and the level of anxiety, and especially the prevalence of depression increase.

Conversion disorder after implant of a spinal cord stimulator in a patient with a complex regional pain syndrome

IMPLICATIONS

This case history describes the treatment of a patient suffering with persistent pain. He was treated surgically with implantation of a spinal cord stimulator. After surgery, a partial paralysis that could not be explained medically and that was probably related to emotional factors occurred, and cognitive behavioral treatment was begun. This paper discusses the importance of considering social and psychological factors when medical treatment options are considered.

Hyperviscoelasticity of epipharyngeal mucus may induce globus pharyngis

Detailed observation reveals a lump of translucent sticky mucus standing in the epipharynx of most globus patients, suggesting that the mucus adherent to the epipharynx causes a globus sensation. The epipharyngeal mucus of 70 consecutive globus patients was sampled via the nasal cavity. Fucose and sialic acid, the determinants of the viscoelasticity of mucus, were measured. Twenty-three patients were also asked to complete the Throat Questionnaire so we could evaluate the correlation between the degree of globus sensation and the viscoelasticity of the mucus. The mucus of 10 healthy subjects was sampled, analyzed, and compared with the data of the patients. The fucose and sialic acid concentrations found in the patients with globus pharyngis were significantly higher than those in the control subjects (Mann-Whitney U test, p < .01). The fucose concentrations correlated significantly with the globus pharyngis scores (Spearman correlation, p < .05). We conclude that there is a close association between stagnant mucus in the epipharynx and globus sensation.

[A case of monoplegia from conversion disorder after spinal anesthesia]

Neurological complications related to spinal anesthesia are exceptional, but their consequences are serious. We report a case of conversion disorder, which was initially diagnosed as monoplegia caused by spinal anesthesia. The patient was a 36-year-old, 88 kg woman with a history of psychogenic aphonia. She underwent plastic surgery for both toes under spinal anesthesia. On the following day, her left leg remained paralyzed with loss of sensation below the knee level. She practiced walking according to rehabilitation program, but paralysis became worse gradually. As the hospitalization was prolonged, she refused to be discharged from the hospital and began to demand the compensation. Her symptoms had not been correlated with the correct anatomical patterns of neurological deficit. The reflexes and muscle's tonus were normal and EMG gave normal findings. The result of neurological diagnosis, confirmed the diagnosis of conversion disorder causing her monoplegia because she was under psychic stressful circumstances from her family. Conversion disorder as a cause of monoplegia after surgery under spinal anesthesia should be kept in mind.

[Psychiatric disorders, personality and traumatic experiences in conversive non-epileptic seizures patients]

AIM

To study the clinical characteristics in patients with conversion non-epileptic seizures, and the influence that traumatic childhood experiences could have in their psychopathologic status and personality.

METHODS

Seventeen patients with non-epileptic seizures confirmed through video-EEG were included. A structured clinical interview (SCID-DSM-III-R), a measure of personality variables (MMPI), and an interview designed for collecting data on personal history of childhood traumas were administered. Descriptive and comparative statistical methods were used.

RESULTS

More than 70% of the sample fulfilled the criteria for two or more simultaneous diagnoses in Axis I, and for at least one personality disorder. The subgroup experiencing childhood traumatic experiences showed more clinically significant MMPI scales, a younger age at correct diagnosis, and higher scores on the MMPI psychastenia and psychopathic deviation scales than the non experiencing childhood traumatics events.

CONCLUSIONS

Our sample of patients with conversion non-epileptic seizures shows a significant level of psychopathology, and the absence of a unique character substrate. Under the generic term of pseudoseizures, a number of subgroups according to childhood traumatic experiences, with different levels of severity and different clinical and personality properties, may be defined.

Psychogenic hearing loss with panic anxiety attack after the onset of acute inner ear disorder

A very rare case of a 50-year-old female showing psychogenic hearing loss with a panic anxiety attack that complicated an acute organic sensorineural hearing loss is reported. At the first visit to our clinic, the patient showed left sensorineural hearing loss with an inner ear disorder pattern. Five days after the onset, her left hearing threshold markedly increased without any subjective signs. On the next day, she suddenly experienced a severe panic attack with anxiety. After the attack, she felt mildly anxious and depressed. A combined therapy using primary corticosteroid therapy for the acute inner ear disorder, psychiatric counseling based on cognitive therapy and the administration of a minor tranquilizer was performed. Her left hearing threshold recovered to within normal ranges except in the high-frequency ranges immediately after the treatment. This case was considered very rare because: (1) the panic anxiety attack occurred in the conversion disorder as psychogenic hearing loss and (2) the psychogenic hearing loss complicated the primary sudden deafness. We suggest that otorhinolaryngologists should have psychiatric knowledge and be able to treat psychogenic hearing loss as a primary care.

[Manifestations of gastroesophageal reflux in the otorhinolaryngology tract]

BACKGROUND

Gastroesophageal reflux disease (GERD) is associated with a wide spectrum of otolaryngologic disorders and extraesophageal complications of the upper aerodigestive tract. Previous studies of patients diagnosed with GERD have reported symptoms such as asthma, chronic cough, pneumonia, laryngitis, but also other oral, rhinopharyngeal and laryngeal disorders, e.g. sore throat, globus sensation, and hoarseness. The objective of this study was to determine the incidence of gastroenterologic diseases in patients complaining of upper aerodigestive, pulmonary, laryngeal, pharyngeal, oral, and cervical disorders that are possibly attributable to GERD.

PATIENTS

This study included 40 patients, who presented to the department of Otolaryngology with chronic complaints of at least one of the following symptoms or disorders during a minimum period of 3 months: dysphagia (n = 28), sensation of globus pharyngeus (n = 28), hoarseness (n = 20), odynophagia (n = 22), heartburn (n = 16), postnasal drip (n = 15), sore throat (n = 22), cough (n = 14), throat clearing (n = 11), laryngospasm (n = 6), and voice fatigue (n = 6). A complete examination of the head and neck was performed. Inflammatory disorders of the nose and the paranasal sinuses could not be confirmed by history, nasal endoscopy and Water's view x-ray or CT-scan of the paranasal sinuses in all patients.

RESULTS

The main otorhinolaryngologic findings were laryngeal lesions (n = 38), including posterior laryngitis, erythema and edema of the interarytenoideal region, and chronic hyperplastic laryngitis. All patients were referred for gastroenterologic evaluation, where esophagogastroduodenoscopy was performed with histological examination of biopsy specimens. Different gastroenterologic diseases such as GERD, gastritis and hiatal hernia were confirmed in 30 of 40 cases, and appeared solely or in combination with each other. GERD was the most frequent gastroenterologic disease (48%), followed by hiatal hernia (45%) and Helicobacter pylori positive antrum gastritis (23%). Patients with GERD were treated with medical antireflux therapy, e.g. 20 mg to 40 mg of the proton pump inhibitor omeprazole daily. There was a remarkably good therapeutic outcome, since laryngeal disorders and findings as the result of gastroenterologic diseases resolved in 29 out of 30 patients. To date, these therapeutic results were maintained for the mean follow-up period of 8 months.

CONCLUSIONS

It is concluded that in many patients, suffering from the above-mentioned otolaryngologic symptoms, occult gastroesophageal diseases are present. However, laryngoscopic findings are subtle and meticulous examination is mandatory. Medical antireflux treatment is effective for relief of symptoms and mucosal healing. Thus, extraesophageal otolaryngologic symptoms and laryngeal manifestations are to be considered as extragastrointestinal manifestations mainly of reflux disease.

[Coexistence of mass hysteria, konzo and HTLV-1 virus in the Democratic Republic of the Congo]

A cross-sectional study was carried out in Pindi located 115 kilometers from Kikwit, Democratic Republic of the Congo to characterize a local school epidemic involving paralysis of the lower extremities, identify risk factors, and establish differential diagnosis with konzo and spastic paralysis related to human T-lymphotropic virus type 1 (HTLV-1). Data was obtained using a qualitative approach based on records, interviews, focus group technique, and neurological examination. Blood tests using the ELISA and western blot tests were performed to detect HTLV-1 and HIV 1 and 2. A total of 41 cases of paralysis were observed between 1994 and 1998. All patients were female and most (n = 28) were between the ages of 16 and 20 at the time of the study. The majority of cases were recorded in 1998 (31 prevalent cases and 16 incidents). Epidemiological data, clinical findings, and laboratory tests suggested that the etiology was mass hysteria with somatic conversion rather than toxic or viral causes in most cases. The psychosocial environment played an important role in the spread of the epidemic. These findings demonstrate the crucial role of the psychosocial environment in the occurrence of mass hysteria and support use of integrated health programs in developing countries.

Postvaccination mass psychogenic illness in an Iranian rural school

In October 1992 after tetanus inoculations of 26 girl students in a village in the Islamic Republic of Iran, an outbreak of psychomotor syndrome occurred in 10. Although only few were affected, the temporary negative impact on public opinion about immunization was serious. Physical and laboratory investigations of the girls were normal. The 10 girls were compared with their 16 classmates. Higher socioeconomic status was protective (P = 0.04) and distance of home from school was relevant (P = 0.03). This is the first report of a health intervention unwarrantedly being held as the cause of an outbreak. The outbreak, however, was managed successfully.

[Clinical aspects of hysteria at the psychiatric clinic of the Fann University Hospital Center. Apropos of a prospective study of 121 cases]

This work was done at the Psychiatry Service of CHU of Fann in Dakar during the year 1994. It is a transversal study made by inquiry on the basis of a questionnaire centered on the clinical description and the starting factors in a population of 1025 adult-patients, received on external consultation. It enabled its authors to realize that hysteria was the second cause of consultation after schizophrenias. The starting factors of troubles are mainly conflicts (disturbance of inter-personal relationship) in 49.6% of the cases, and difficulties of daily life, causing annoyance and stress. On the clinical level, polymorphism of the hysterical signs has been found out as much in the level of paroxysmal signs, as in the level of lasting signs. The frequency of big Charcot attacks, often considered as unusual, has been observed in this study in 10% of the patients. Moreover, on the level of the personality structure, only 103 patients have been identified (i.e. 85.1%) to have shown a hysterical personality type.
