Eating habits during quarantine: Investigating the role of emotions and loneliness in a sample of adults in Greece

Introduction

Imposing quarantine as a measure to manage the coronavirus pandemic is a stressful event that is often associated with negative psychological effects. Eating habits seemed to be significantly affected during the quarantine, while strong negative emotions were triggered as the feeling of loneliness increased at the same time.

Objectives

This study aims to investigate the eating habits of individuals during quarantine and the role of positive and negative emotions and loneliness in shaping these habits.

Methods

An online cross-sectional study was performed using 3 validated scales, EAT-26 (3 subscales: Dieting, Bulimia and Food Preoccupation, Oral Control), Modified Differential Emotions Scale and UCLA Loneliness Scale. Data was collected between April and May 2021 mainly from social media platforms. Statistical analyses included linear regression and mediation analyses.

Results

Abnormal eating habits were detected in 25% of the participants (N= 450, ages 18-74) while the majority reported medium rates of negative/positive emotions and loneliness. Female sex is associated with abnormal eating habits (p=0.010) and mainly dietary behaviors (p=0.029). Negative emotions (p=0.032) and loneliness (p=0.001) seem to be predictive factors of eating habits in general and bulimic behaviors. Negative emotions correlate directly with eating habits. However, we found a significant mediation of loneliness (p=0.032). Furthermore, the observed association between negative emotions and bulimia is partly mediated by loneliness (p=0.018).

Conclusions

Negative emotions and loneliness seemed to play an important role in shaping eating habits during quarantine. Multilevel public health interventions are needed to address the negative effects of quarantine and pandemic in general.

Affective disorder associated with post-traumatic epilepsy, misdiagnosis and under treatment: A case report

Introduction

A history of traumatic brain injury (TBI) is often associated with acquired epilepsy, which is associated with psychiatric co-morbidity, that when undetected might lead to misdiagnosis and mistreatment.

Objectives

The objective is to present the case of a 47-years-old male with a history of TBI and undetected acquired epilepsy, with a subsequent treatment resident mood disorder that was lead to a full clinical remission once epileptic activity was controlled using anti-seizure monotherapy.

Methods

After compulsory admittion to our inpatient psychiatric unit because of suicidal ideation and persistent aggressive behavior with volatile mood swings, the patient was fully evaluated and his psychiatric and medical histories were recorded. A brain CT scan and EEG were performed. Laboratory tests excluded other medical co-morbidity.

Results

The patient had a previous history of TBI and subsequent multiple episodes of mood disorders that failed to reach full remission even if treated with antidepressives and antipsychotics for adequate time and dosage according to current quidelines. EEG was positive for epileptiform activity with sporadic slow theta waves and right frontotemporal epileptic-like features while the patient was free of clinical seizures. Carbamazepine was initiated and titrated up to 1200mg daily leading to the full remission of the initial clinical symptoms along with the EEG findings’ improvement. The patient remained stable with his functionality at its utmost recovery during the two-years follow-up evaluations.

Conclusions

TBI induced epilepsy might be under-diagnosed in the absence of clinical seizures leading to the mistreatment of the associated psychiatric disorders that could be the only clinical presentation of the underlying pathology.

A case report of eosinophilia associated with risperidone withdrawl in a patient with schizophrenia

Introduction

Risperidone, a second generation antipsychotic, shows high affinity with serotoninergic and dopaminergic D2 receptors, but also adrenergic and H1 histaminergic receptors. Previous studies have shown an increase in eosinophile count associated with the second-generation antipsychotics through the histaminergic path.

Objectives

The presentation of a case in which eosinophilia was associated with risperidone withdrawl which has not been described so far.

Methods

A 46-year-old woman with schizophrenia diagnosed at the age of 22 was admitted in our inpatient psychiatric clinic with psychotic symptoms relapse after she voluntarily discontinued risperidone. The patient was fully evaluated with full laboratory tests, a brain CT scan, EEG and her medical and psychiatric histories were recorded.

Results

Risperidone was reinitiated but due to the persistence of symptoms it was switched to clozapine which lead to full remission. It was observed though, that while gradually decreasing risperidone dosage (Figure 1.), eosinophile count was raising and it was normalized after complete discontinuation. Eosinophilia was also present in other instances that the patient discontinued taking risperidone according to her personal history. Other causes of eosinophilia (allergic, inflammatory) were fully excluded.

Conclusions

Risperidone discontinuation could lead to an elevated eosinophile count. There is limited research in this topic and it is yet to be clarified whether the elevation is due to stopping one antipsychotic or switching between two different antipsychotics. It is important to run laboratory tests regularly with every treatment modification.

COVID-19 lockdown and its impact on mental health in various population groups in Greece: A cross-sectional study

Introduction

COVID-19 pandemic and lockdown has brought a serious impact on physical and mental health.

Objectives

The purpose of the present study was to estimate the impact of the first lockdown in Greece, on both quality of life and anxiety levels in different occupational groups.

Methods

A cross-sectional on- line survey was conducted from 20^th of April to 4^th of May 2020. A 24-item anonymous questionnaire was administered to collect basic demographic and socioeconomic data. The 5-item WHO Well-Being Index (WHO-5, 0-100%, cut-off 52%) and the Generalized Anxiety Disorder Assessment (GAD-7) tools were used to assess well-being and anxiety, respectively. Statistical analysis was performed with SPSS for Windows v.24.0 Statistical Package.

Results

A total of 575 participated in the study, 62.8% females, 48.5% aged between 40 to 59 years. 32.5% were employed in education sector, 32.5% in health sector and 20.3% as season workers in tourism sector. Males showed slightly higher levels of wellbeing (52.1 vs. 47.3, p=0.023) and lower levels of anxiety (7.1 vs. 8.2, p=0.023) compared to females. Factors associated with higher wellbeing and lower anxiety were higher education and income level, optimism, taking less protection measures, and being seasonal worker. Furthermore, participants with comorbidities and symptoms like headache, musculoskeletal pain, as well as feeling depressed or stressed revealed lower wellbeing and higher anxiety scores.

Conclusions

Our study revealed an overall poor wellbeing and mild to moderate levels of anxiety during the lockdown. Actions should be taken to address and to prevent its serious impact on mental health.

Anxiety and depression among students in a greek university amidst COVID-19 pandemic

Introduction

The coronavirus pandemic has challenged the world with an unprecedented situation. Social distancing, self or quarantine isolation, personal hand hygiene, self-protection, and the fear of becoming infected with the virus, come with a psychological fallout. The COVID-19 pandemic has affected students around the world, in terms of their education and lifestyle.

Objectives

To investigate the impact of COVID-19 pandemic on the students’ mental health and well-being at the University of Patras, in Western Greece.

Methods

An online questionnaire was prepared to collect responses from students during April 2020. Socio-demographic data, academic status, opinions about distance learning, changes in daily routine during the lockdown and anxiety and depression scores, according to the Greek version of the Hospital Anxiety and Depression Scale (HADS), were gathered.

Results

The total number of responders was 2009, of which 67.3% women. During lockdown, the 68% of the students returned to their family home. Anxiety and depression scores were higher in students with a low income, poor self-rated health, not informed about COVID-19, not satisfied with distance learning and being annoyed at staying home. Prevalence of anxiety and depression was found to be 35.8% and 51.2%, ranging from 26.7% to 48.2% for anxiety and from 36.3% to 60.5% for depression in Health Sciences and Humanities and Social Sciences, respectively.

Conclusions

Depression rates among university students in Greece were alarmingly high, denoting the impact of lockdown and changes in students’ life, due to the COVID-19 pandemic.

Prevalence of post traumatic stress disorder in children with mild traumatic brain injury

Introduction

Children with traumatic brain injury (TBI) are at risk for post-traumatic stress disorder (PTSD). The vast majority of TBI are of mild severity (MTBI), however, they may develop persistent neurophysiological symptoms.

Objectives

The purpose of this study was to investigate the incidence of PTSD in children with MTBI in Western Greece.

Methods

A one-year prospective study was conducted at the Children Hospital of Patras. A total of 175 children aged 6-14 years screened for risk of PTSD at one-week and one-month post-injury, completing the Child Trauma Screening Questionnaire (CTSQ). The Children’s Revised Impact of Event Scale (CRIES 13) was administered to the parents, to inquire their assessment of PTSD in the children. Statistical analysis was performed with IBM SPSS v.22.0

Results

There were 59 (33.7%) children (27.2% boys, 45.9% girls) whose screen result was at risk. At the rescreening one-month postinjury, 9.9% were still at risk. Parents assessed presence of PTSD in 19% of their children at one-week and in 3.9% at one-month post-injury. There was a positive correlation between parenting and child reporting on symptoms of PTSD in children. However, 23.4% mistakenly estimated their children did not experience stress while in fact they did and 24.2% mistakenly estimated the contrary.

Conclusions

The findings revealed the risk of PTSD even in mild TBI, justifying thus the screening to identify these children for intervention strategies. On the other hand, the rescreening demonstrated that not all at-risk children required intervention, since a natural remission in PTSD symptoms was observed one-month post-injury.

Evaluation of depression and anxiety control in greek patients with major depressive disorder with/without generalized anxiety disorder and cardiovascular disease–pronoi study

Introduction

Patients with depression are likely to eventually develop Cardiovascular disease(CVD) and have a higher mortality rate than general population. In addition, anxiety disorders, especially Generalized Anxiety Disorder (GAD), may be associated with mortality and other adverse cardiac outcomes.

Objectives

Evaluation of depression and anxiety control in Greek patients with Major Depressive Disorder (MDD) with/without GAD and CVD, under 6 months of treatment with citalopram, and/or quetiapine, and/or pregabalin.

Methods

565 patients with MDD with/without GAD, enrolled in this observational, study (NCT03317262). The subgroup of 133(24%) patients had CVD. Severity of MDD and GAD symptoms was evaluated using the HAM-D and HAM-A Scores at baseline (V₁) and after 6 months (V₃) respectively.

Results

Mean HAM-D score in patients with CVD without GAD, at V₁ and V₃ was 23.94±7.51 and 8.14±4.65 respectively (p<0.0001). Similar results were observed in patients without CVD without GAD (HAM-D score 26.67±8.79 at V₁ and 7.44±4.40 at V₃). Mean HAM-A score in patients with CVD and GAD at V₁ and V₃ was 25.64±6.38 and 8.98±3.93, respectively (p<0.0001). Same magnitude reduction in HAM-A score was observed in patients without CVD and GAD, 26.27±8.16 at V₁ and 9.28±6.48 at V₃ (p<0.0001). Patients’ depression symptoms with/without CVD and GAD showed also a significant reduction between V₁ and V₃.

Conclusions

MDD patients with CVD without GAD, had a marginally lower baseline HAM-D score versus patients with GAD. After 6 months of treatment with citalopram, and/or quetiapine, and/or pregabalin the improvement of depressive and anxiety symptoms was almost equal between MDD patients with/without GAD regardless of the presence of coexisting CVD.

Symbol Digit Modalities Test: Greek Normative Data for the Oral and Written Version and Discriminative Validity in Patients with Multiple Sclerosis

OBJECTIVES

The purpose of this study was to generate normative data on the Symbol Digits Modalities Test (SDMT) for the written and oral versions in the Greek adult population. We also investigated the test's validity in discriminating the performance of healthy adults from two groups of adults diagnosed with relapsing remitting (RRMS) and secondary progressive (SPMS) multiple sclerosis.

METHOD

The sample consisted of 609 healthy men and women between the ages of 18 and 65. All participants were monolingual native Greek adult speakers. Each healthy participant was administered either the written (n = 460) or oral (n = 149) versions of the SDMT. Discriminant validity was examined by comparing 35 healthy participants who had completed the oral version of the SDMT to 35 age - and education-matched RRMS and SPMS patients.

RESULTS

Linear regression models explained between 36% and 55% of the variance in the SDMT oral and written version scores. Age was the strongest predictor of difference in SDMT written and oral version performance, followed by education that also accounted for a further proportion of the SDMT variance. On the contrary, gender was found not to contribute significantly to the variance in the SDMT for either the written or the oral versions. As a result, age- and education-adjusted norms were generated. Regarding the tests discriminative validity, we found that both MS patient groups scored significantly lower than the healthy group.

CONCLUSIONS

This is the first study to provide comprehensive normative data for the SDMT in the adult population in Greece, impacting the future practice of neuropsychological assessment in this country.

Clinical implementation of preemptive pharmacogenomics in psychiatry: Τhe "PREPARE" study

PREemptive Pharmacogenomic testing for Preventing Adverse drug REactions (PREPARE) is the first prospective, pre-emptive pharmacogenomic study conducted in Europe, within the frame of the Horizon 2020 program. It aims to determine whether implementing pre-emptive pharmacogenomics (PGx) testing of clinically relevant biomarkers, so as the dose and drug selection to be guided, will result in an overall reduction of both the occurrence and the severity of drug-genotype-associated adverse drug reactions (ADRs). To achieve that, two groups of patients will be recruited; one that will receive treatment according to standard clinical practice and one other that will receive pharmacogenomic-guided treatment. The Laboratory of Pharmacogenomics and Individualized Treatment of the University of Patras, which coordinates and represents Greece in this study, in collaboration with the Department of Psychiatry of the General University Hospital of Patras, the Department of Psychiatry of the Hospital "Attikon" and the Departments of Psychiatry of the Psychiatric Hospital of Athens "Dafni" is going to recruit 1500 psychiatric patients that are going to receive antidepressant or antipsychotic treatment. Our scientific hypothesis is that patients who receive pharmacogenomic guided drug and dose selection will experience 30% less ADRs than patients following standard care. Eligible drugs for inclusion in the PREPARE study, are those for which the clinical decision regarding drug and dose choice can be guided according to the Dutch Pharmacogenomics Working Group Guidelines (DPWG). Overall, 7 antidepressants (citalopram, escitalopram, sertraline, paroxetine, venlafaxine, clomipramine, amitriptyline) and 3 antipsychotics (haloperidol, zuclopenthixol, aripiprazole) related to 17 genetic variations in 2 genes (CYP2D6, CYP2C19) will be examined. Occurrence, severity and causality of adverse drug events (ADEs) will be assessed during monitoring, at month 1 and 3 after starting the index-drug, and at the end of each arm, by using the Common Toxicity Criteria for Adverse Events Scale (CTCAE) and the Liverpool Causality Assessment Tool (LCAT), respectively. The results of our study are expected to significantly contribute to the improvement of psychiatric patients' quality of life, by helping to provide the right drug, to the right dose in terms of efficacy, safety and cost-effectiveness.

Frontotemporal dementia misdiagnosed as schizophrenia or other psychotic disorder

Introduction

Frontotemporal dementia (FTD) encompasses a group of clinical features that include personality and behavior changes (disinhibition, social isolation, antisocial behavior, compulsion) and executive dysfunction (poor planning, loss of judgment and loss of insight). These features may lead to an incorrect diagnosis of a primary psychiatric disorder.

Objectives

To emphasize the difficulties in making a clinical distinction between early frontotemporal dementia and other psychiatric diseases.

Methods

We describe 11 patients who suffered from FTD, while initially had diagnosed with primary psychiatric disorders. The correct diagnosis was achieved by psychiatric and neuropsychological evaluations (WAIS SCALE, ACE-R, MMSE), neuroimaging studies (MRI 7/11, SPECT 8/11) and applying the international consensus criteria for FTD.

Results

All patients (5 males and 6 females) were initially diagnosed with psychiatric disorders: schizophrenia (2/11), bipolar disorders (4/11), depression (5/11), schizoaffective disorder (1/11), somatization disorder (1/11), personality disorders (2/11), malingering (1/11), alcohol dependence (1/11), while 5 patients had more than one diagnosis. The age of onset varied from 19 to 53 years old. Final diagnosis of FTD was delayed on average 6,5 years from the onset of symptoms.

Conclusion

Clinicians should be familiar with the clinical entity of FTD and its difficult distinction from other psychiatric disorders. A possible hospitalization of a patient with FTD in a psychiatric department and the social impact that it brings may be avoided. On the other hand, the proper care of FTD patients (pharmacological and psychosocial) improves the quality of life of patients and their caregivers.

Compulsory admissions in southwest Greece 2010-2011: A descriptive report

Compulsory admissions represent a significant proportion of psychiatric hospitalizations. A wide variation seems to exist internationally regarding legal frameworks, administrative procedures, detention rates and clinical practice. The aim of the present study is to describe qualitative and quantitative features of compulsory admissions in a large administrative area in southwest Greece, in order to identify targets for future research and possible remediation. Involuntary assessments and admissions in the Department of Psychiatry of the University Hospital of Patras were retrospectively assessed, during a 12-month period, for demographic features and data regarding legal procedures. Diagnoses following compulsory first assessment and at discharge were recorded for the patients who were admitted in our department. During the period of observation, 218 compulsory assessments were made, corresponding to 190 patients and resulting in 183 compulsory admissions. Thirty five cases (16.1%) were assessed as not justifying hospitalization and corresponded mainly to the diagnoses of alcohol and/or substance abuse or dependence. Involuntary hospitalizations represented 44.9% of all psychiatric admissions in our department. Diagnosis at first assessment was most frequently psychosis (68.4%). Diagnoses at discharge were most often schizophrenia (52.8%) and bipolar disorder (21.3%). A history of multiple hospitalizations (>5) was observed in 17 (15.8%) patients, whereas 46 patients (42.6%) were hospitalized for the first time, and 13 (11.7%) exhibited their first psychotic episode. Of the 108 patients who were admitted in our department, 88 (81.5%) declared that they did not wish to attend the court hearing, 7 (6.5%) were not able to attend due to severe health condition, and only 13 (12.0%) actually presented in court. Concluding, current situation regarding legal procedures, involuntary admissions and mental health care in Greece is rather far from satisfying. Future directions should include the systematic recording of mental health care parameters, such as compulsory hospitalizations, as well as efforts to improve these parameters and the existing legal framework and procedures.

Postpartum Depression in a Public Hospital in Cyprus. Prevalence, Risk Factors

Introduction

Postpartum depression (PPD) is a serious mental health condition. Untreated PPD places the mother and infant at risk and is associated with significant long-term effects on child development and behavior.

Objectives

Appropriate screening for and prompt recognition and treatment of depression after the birth of a child are essential for maternal and child well-being.

Aims

The purpose of the present study was to estimate the prevalence of PPD in the first 5 days after the birth of a neonate and to investigate associations with several risk factors.

Methods

A cross-sectional study was conducted among 150 mothers, in a public obstetric hospital in Nicosia, Cyprus. A questionnaire was administered including socio-demographic characteristics. The Greek version of the Edinburgh postnatal depression scale (EPDS), a 10–item questionnaire to identifying women who are at risk of PPD, was used to estimate depression among the participants.

Results

According to EPDS, 42% of the mothers screened positive for risk of developing PPD. Higher risk was observed in very young mothers (<20 years) (66.6% vs 15%), in women with history of psychological disorders (86.95% vs 33.85%), in single mothers (71.69% vs 22.8%), in women with serious problems during the pregnancy (74% vs 23.95%) and in mothers with not healthy neonate (75.7% vs 32.4%).

Conclusion

The study reveals a high prevalence of PPD and identifies various risk factors associated with developing PPD. The use of maternal depression screening programs such as the EPDS may help to recognize an elevated risk of postpartum depression and to ensure a healthier mother-child relationship.

The birth of Athena – Psychodynamic formulation and case report

Introduction

Athena possesses a special place among the Greek Gods, as she was born from her father, according to an extreme patriarchal model with a marked depreciation of the maternal role. Zeus had swallowed and absorbed the mother of Athena, Mites, because of an oracle that if Mites gave birth to a boy, the boy would take his throne. When the time comes, Zeus commands Hephaestus to cleave his forehead with an axe, and then Athena leaps fully armed and shouting her cry of war, in front of the astonished Gods. The next moment she puts her weapons down, as a token of obedience and devotion. The exceptionally close bond between father and daughter is evident through their uniquely confidential relationship. The ancient myth is paralleled, from a psychodynamic aspect, with the case of a narcissistic patient receiving psychodynamic psychotherapy.

Methods

Case report.

Results

A case of a woman with narcissistic personality features and depressive symptoms is described, presenting with the complaints of withdrawal, self-depreciation, passivity, and agoraphobia. Psychodynamic factors defining her pathology are her narcissistic and sexualized relationship with her father, whereas the relationship with her mother has been depreciated. The patient experiences an intrapsychic conflict of reciprocal idealization, against her anger and fear for her father, resulting in the symptoms of agoraphobia and passivity.

Conclusion

Like Athena, who puts her weapons down, the patient resigns from her will for autonomy and moves to a passive position, as a result of her entrapment in her idealized relationship with the father.

[Prevalence of depression among the elderly]

Depression is the most common mental health problem among older people, posing a critical impact on their well-being and the quality of life. The objective of the present study was to estimate the prevalence of depression in elderly population of an urban area and to investigate the association with various aggravating or protective factors. The sample consisted of 239 subjects, aged >60 years, members of "daycare centers for older people" (KAPI) in the municipality of Patras, W-Greece. A questionnaire was developed to collect basic demographic and socioeconomic data, including three questions from the "European Health Interview Survey" (EHIS), regarding self-reported and/or by a physician diagnosed depression. Moreover, to all participants the Greek validated version of the Geriatric Depression Scale (GDS-15) was applied, to screen the elderly for depressive symptoms. The scores of the GDS were a) compared to the corresponding answers of the EHIS questions and b) associated to the various recorded basic parameters. Statistical analyses were performed using the SPSS v. 17.0. The results of the GDS indicated 45% of the studied population having depressive symptoms (36% moderate, 9% severe), while having ever been affected with chronic depression reported 49 (20.5%) and out of them 34 (66.8%) stated to have been diagnosed by a medical doctor. In detail, out of the 162 (67.8%) subjects reporting never have been affected by a depression, 37 (22.8%) and 8 (4.9%) screened positive for moderate and severe depressive symptoms, respectively. In 27 individuals who reported not to know if they have depression, 16 revealed depressive symptoms using the GDS. Depressive symptoms were more frequent in women (54.6% vs 37.4%, p=0.027), in not married, including divorced and widowed, compared to married (55.6% vs 38.9%, p=0.038) and in subjects living alone at home (62% vs 38.1%, p=0.003). Depressive symptoms were more frequent in elderly with chronic diseases compared to elderly without comorbidity (50.8% vs 27.5%, p=0.02). High prevalence of depressive symptoms in elderly population is evident, but rarely recognized. The systematic use of short GDS versions in Primary Care may increase detection rates of depression among the elderly.

Validation of the German revised Addenbrooke's cognitive examination for detecting mild cognitive impairment, mild dementia in alzheimer's disease and frontotemporal lobar degeneration

BACKGROUND/AIMS

The diagnostic accuracy of the German version of the revised Addenbrooke's Cognitive Examination (ACE-R) in identifying mild cognitive impairment (MCI), mild dementia in Alzheimer's disease (AD) and mild dementia in frontotemporal lobar degeneration (FTLD) in comparison with the conventional Mini Mental State Examination (MMSE) was assessed.

METHODS

The study encompasses 76 cognitively healthy elderly individuals, 75 patients with MCI, 56 with AD and 22 with FTLD. ACE-R and MMSE were validated against an expert diagnosis based on a comprehensive diagnostic procedure. Statistical analysis was performed using the receiver operating characteristic method and regression analyses.

RESULTS

The optimal cut-off score for the ACE-R for detecting MCI, AD, and FTLD was 86/87, 82/83 and 83/84, respectively. ACE-R was superior to MMSE only in the detection of patients with FTLD [area under the curve (AUC): 0.97 vs. 0.92], whilst the accuracy of the two instruments did not differ in identifying MCI and AD. The ratio of the scores of the memory ACE-R subtest to verbal fluency subtest contributed significantly to the discrimination between AD and FTLD (optimal cut-off score: 2.30/2.31, AUC: 0.77), whereas the MMSE and ACE-R total scores did not.

CONCLUSION

The German ACE-R is superior to the most commonly employed MMSE in detecting mild dementia in FTLD and in the differential diagnosis between AD and FTLD. Thus it might serve as a valuable instrument as part of a comprehensive diagnostic workup in specialist centres/clinics contributing to the diagnosis and differential diagnosis of the cause of dementia.

Dynamic F wave study in patients suffering from peripheral arterial occlusive disease

OBJECTIVE

To prospectively detect significant transient F wave abnormalities obtained after exercise in patients with peripheral arterial disease (PAD) and to assess the potential diagnostic sensitivity of dynamic F wave study in such a context.

PATIENTS AND METHODS

A series of 40 electrical stimuli were delivered to the peroneal and the posterior tibial nerves of 25 patients with PAD in order to obtain F waves at rest and post-exercise. The following variables were estimated and the obtained pre- and post-exercise data were compared: F persistence, F wave latency, amplitude, duration and F chronodispersion. For each nerve studied, the minimum, average and maximum values were calculated. Conventional electrophysiological data were also collected pre- and post-exercise and the data obtained were also compared. Twenty-five healthy age-, gender- and height-matched individuals served as controls.

RESULTS

No evidence of conventional nerve conduction abnormalities was recorded either pre- or post-exercise in the group of patients. As regards the peroneal nerve, the significantly reduced F wave persistence (P = 0.007) and maximum F wave amplitude post- as opposed to pre-exercise (P = 0.05)- were the main findings to emerge. The average (P = 0.017) and the minimum duration (P = 0.005) of tibial F waves were also significantly increased post- compared with pre-exercise. Insignificant differences were observed between pre- and post-exercise neurophysiological and F wave values in the group of controls.

CONCLUSION

Given the observed absence of conventional neurophysiological abnormalities, the detection of dynamic F wave changes supports the view of an increased diagnostic sensitivity of this method in patients with mild PAD.

Efficacy of oxcarbazepine for prophylaxis against cumulative oxaliplatin-induced neuropathy

We conducted a randomized, open-label, controlled trial to assess the efficacy of oxcarbazepine for prophylaxis against oxaliplatin-induced peripheral neuropathy (OxIN). Thirty-two patients with colon cancer received 12 courses of the FOLFOX-4 regimen and were randomly assigned to receive oxcarbazepine (600 mg BID) or chemotherapy without oxcarbazepine. The incidence of OxIN was strikingly decreased in patients receiving oxcarbazepine (31.2% vs 75%). Oxcarbazepine may prevent OxIN symptoms. Further larger placebo-controlled trials are warranted to confirm our results.

Factors associated with poor compliance of patients with epilepsy driving restrictions

The authors sought to identify factors associated with poor compliance with driving restrictions due to a diagnosis of epilepsy. They compared the demographic and clinical characteristics of 60 patients with epilepsy who, despite the authors' recommendation, continued to drive, with those of 60 age- and sex-matched epileptic patients who refrained from driving. The results showed that patients with epilepsy do not comply with driving restrictions, mainly for employment-related reasons.

Lunar phases and seizure occurrence: Just an ancient legend?

The authors retrospectively reviewed all neurologic records of an emergency unit from 1999 to 2003 to identify a potential association between lunar phases and seizure occurrence. Overall 859 patients admitted for seizure occurrence were divided into the four quarters of the synodic month according to moon phases. A significant clustering of seizures around the full moon period was observed, supporting the ancient belief of periodic increased seizure frequency during full-moon days.

Factors affecting smoking in schizophrenia

There is an increased frequency of smoking among patients with schizophrenia. However, it is unknown whether the smoking behavior of the patients is similar in all schizophrenia subtypes, as well as which is the relationship between smoking initiation and disease onset. Four hundred six patients with DSM-IV schizophrenia were interviewed to determine the smoking status in relationship to gender and schizophrenic subtype, and to other factors that could affect or be affected by smoking. The frequency of smoking among patients (58%) was significantly greater than in subjects from the general population (42%) (P =.000005). Male patients smoked significantly more frequently (70%) than the corresponding control subjects (50%) (P =.000006), whereas the difference failed to reach significance between female patients (41%) and control subjects (32%). Among male patients, the number of smokers was significantly greater than in the controls in the paranoid (77%), undifferentiated (72%), and residual (78%) subtypes, whereas there was no significant difference in the disorganized (44%) and catatonic (22%) subtypes. The findings show that the frequency of smoking in schizophrenia patients increases with increasing positive symptoms and decreases with increasing negative symptoms. Male and female smoking patients consumed approximately 10 cigarettes per day more than the corresponding control subjects (P <.000001). In 86% of the patients, smoking initiation occurred before the disease onset. Among patients who smoked, smoking initiation and disease onset occurred at age 18.7 +/- 4.4 and 24.1 +/- 6.1 years, respectively (P <.000001). It appears that smoking in schizophrenia is influenced by gender and subtype. However, the nature of this association remains uncertain because in the vast majority of the patients smoking initiation occurs earlier than the disease onset.

Mutation screening of the Wolfram syndrome gene in psychiatric patients

Wolfram syndrome, a rare autosomal recessive neurodegenerative disorder, was originally described as a combination of familial juvenile-onset diabetes mellitus and optic atrophy. It was later demonstrated that Wolfram syndrome patients were highly prone to psychiatric disorders. Mutations in exon 8 of the Wolfram syndrome gene account for 88% of the patients with Wolfram syndrome. To examine whether the gene responsible for causing Wolfram syndrome is involved in psychiatric disorders, we screened exon 8 of the Wolfram syndrome gene for mutations in 119 patients with schizophrenia, one patient with schizoaffective disorder, 12 patients with bipolar disorder and 15 patients with major depression, using sequence analysis. In Wolfram syndrome patients, this gene has been shown to have primarily nonsense or frameshift mutations, which would result in a premature truncation of the protein. None of the psychiatric patients screened in this study carried these types of mutations. We identified, however, 24 new variations whose significance remains to be determined.

Psychological factors in the development of mood disorders with a seasonal pattern

The psychiatric records of a 7-year period were searched for cases with seasonal mood disorders. Among 358 cases with a mood disorder there were 41 patients with 3 or more admissions, 4 of which were demonstrating a seasonal pattern. It was found that the depressive or manic episodes of these patients were anniversary reactions associated with intense traumatic experiences in childhood, adolescence or adulthood. The seasonal pattern of the depressive episodes fulfilled the DSM-IV diagnostic criteria. The time and sometimes the place of the traumatic event acted as triggers eliciting the clinical symptoms. This study showed that anniversary reactions may constitute a subgroup of seasonal mood disorders manifesting both depressive and manic episodes, which are precipitated primarily by psychological factors rather than climatic conditions.

Anniversary reaction as seasonal mood disorder

We describe the case of a patient who, after a traumatic experience at the age of 12, had a series of anniversary depressive episodes at 16, 17, 18 and 19 years of age, followed by a series of anniversary manic episodes at the ages of 21, 23, 24, 25 and 26 years. All of these episodes occurred almost always a few days before or after the date of the accident and only when the patient was residing in his home town, the place of the traumatic event. The case fulfills the DSM-III-R criteria for seasonal mood disorder, but differs from previously described cases in that: (a) both depressive and manic episodes developed at the same time of the year, and (b) the illness was precipitated by psychosocial factors rather than climatic conditions.
