Substance abuse and cancer.

Substance abuse is a health problem with serious psychological and psychiatric dimensions and multiple social and economic consequences. Cancer is a disease that threatens not only life and physical integrity but mental health as well. Oncology patients suffer from mental disorders in high rates, especially from depression and anxiety. The role of substance abuse in the pathogenesis of cancer is studied systematically, since there are research data supporting the mutagenic effects of certain substances. It has been supported that a possible dysregulation of the immune system is linked to the oncogenic processes induced by substances of abuse. Specifically, opioids are the first addictive substances that have been identified as oncogenic factors. However, conflicting results have been offered by experimental animal studies, which showed that opioids, such as morphine, depending on the dosage administered, may not only enhance the process of tumor growth, but also inhibit it. Additionally, research data indicate that the use of cannabis may be associated with cancer, either as an independent factor or in relation to other mutagenics, although it is not yet clear to which extent these effects may be connected to the disease, especially once the consumption of tobacco and alcohol by these patients are taken into account. However, it has been argued that certain cannabinoids may have biological -anticancer- activities which could be used therapeutically without being accompanied by the corresponding 9-tetrahydrocannabinol psychoactive effects. It is well known that alcohol is a risk factor for developing head and neck cancer, and epidemiological studies indicate that the higher the consumption of alcohol, the more mortality due to cancer increases. In addition, it is suggested that there is no safety level for alcohol consumption regarding the risk of developing cancer; that is even a minimum daily consumption is associated with the occurrence of certain types of cancer. Specific components have been identified in tobacco, which are considered to be carcinogenic and responsible for tumor development in various sites. Moreover, complicated psychiatric problems arise due to substance abuse in cancer patients, either in the context of pain treatment, or under pre-existing dependence. The rational use of opioid analgesics, when it is medically required as suggested by the health professionals specialized in the treatment of acute pain in cancer patients, could be a therapeutic option. Substance abuse reduces treatment compliance, worsens cancer prognosis and seems to be a negative factor for the quality of life of these patients. Current literature highlights the importance of appropriate psychiatric interventions to address substance abuse in cancer patients.

[Attempted suicide during the financial crisis in Athens].

Suicidal behavior is considered as the result of complex cognitive and emotional processes and it is a timeless, global and multifactorial phenomenon. Periods of financial crises in the past, such as the Great Depression in the USA in 1929 and the economic crises of Asia, Russia and Argentina in the late 1990s, have been associated with impairment of mental health of the economically affected. Unemployment, job insecurity, debts, poverty and social exclusion seems to lead to higher incidence of anxiety and depressive symptoms and increased suicidality. Alcohol and substance use and the reduction of the state budget for health services reinforce the negative effects of the economic recession on mental health. The financial crisis which currently affects many European countries began in 2008 and its impact on the mental health of European citizens is in progress. Greece is probably the most affected country by the European financial crisis. The aim of this study is to investigate the potential impact of the crisis' consequences on the attempted suicide rates in the Athens population and the differentiation of suicide attempters on social, demographic and clinical-psychopathological parameters during the crisis. A retrospective study was conducted. The semi-structured records of 165 attempters who were hospitalized in the Internal Medicine Clinics of the "Sotiria" General Hospital in Athens, after attempted suicide in the years 2007 and 2011, before and during the financial crisis respectively, were studied. Among suicide attempters 95(57.6%) were suffering from mental disorders. Most often diagnoses were these of mood disorders (n=60, 63.2%). Demographic data, current psychiatric disorder, previous suicide attempt and severity of psychopathology at the time of suicide attempt were recorded for each patient. Furthermore, the severity of each suicide attempt was estimated. Suicide attempts were 70 in 2007, before the financial crisis (mean age 36.9 years, 71% women) and 95 in 2011, during the financial crisis (mean age 41.0 years, women 65%). There is an increase of suicide attempts by 35.71%. There were no statistically significant differences between the two periods regarding the gender and age of attempters. There was a statistically significant increase of unemployed (p=0.004), as well as of married/widowed/divorced (p=0.02) suicide attempters during the crisis. There was not statistically significant difference in the severity of suicide attempts before and during the economic crisis or the severity of psychopathology of the attempters. The financial crisis is probably associated with upward trend in attempted suicide of the Athens population. Most affected are those who are unemployed, married, widowed, divorced. Suicide prevention programs are essential for the accurate and timely identification and the immediate and effective management of this special high risk group of attempters during the financial crisis.

[Psychological burden of patients diagnosed with obstructive sleep apnea].

Obstructive sleep apnea syndrome (OSAS) is characterized by repeated episodes of upper airway obstruction during sleep, which leads to the presence of excessive daytime drowsiness. Regarding the psychological comorbidity in patients diagnosed with OSAS, previous studies focused mainly on depressive and secondarily on anxiety symptoms. Due to the lack of research data regarding the prevalence of anxiety and depressive symptoms as well as of alexithymic characteristics in patients with OSAS in Greece, the aim of the study was to record the above symptomatology in a sample of Greek OSAS patients and to investigate its relation to the respiratory parameter (Apnea-Hypopnea Index, AHI) of polysomnography. The study was conducted in a certified sleep laboratory. Thirty five randomly selected patients who attended the laboratory with symptoms of daytime drowsiness, fatigue, disrupted sleep and snoring, were examined for anxiety, depression and alexithymia using the Spielberger Trait Anxiety Inventory (STAI), the Beck Depression Inventory (BDI) and the Toronto Alexithymia Scale (TAS-20), respectively, 24 hours prior to being submitted to polysomnography. All 35 patients met the inclusion criteria of the study (age≤75 years, no other chronic diseases and no history of major psychiatric disorders). Six patients did not meet the diagnostic criteria for OSAS and were thus used as the control group of the study. A high prevalence of anxiety (41.4%) and depressive (55.2%) symptoms and of alexithymic characteristics (41.4%) was observed in OSAS patients. Although the control group showed a higher prevalence of anxiety (66.7%) and depressive (83.3%) symptoms, there were no differences between the two groups (STAI: t=-0.927, p=0.360, BDI: t=-1.537, p=0.134, TAS-20: t=0.196, p=0.846). With regard to severity, no differences were observed between control, mild, moderate and severe OSAS subgroups (STAI: F=0.583, p=0.660, BDI: F=0.829, p=0.488, TAS-20: F=0.987, p=0.412). Females scored higher on the BDI and on the STAI compared to males (STAI: t=-2.38, p=0.039, BDI: t=-3.59, p=0.01). Finally, no correlation was observed between psychometric scores and AHI (Pearson correlation p>0.05). The study confirms the high prevalence of anxiety and depressive symptoms which has been found in previous studies. Furthermore, we found a high prevalence of alexithymic characteristics, a factor that has not been investigated previously and which is positively correlated with anxiety symptoms. The coexistence of alexithymic characteristics may further complicate the clinical manifestations of OSAS due to the fact that patients with alexithymia typically have difficulty in indentifying and describing their underlying psychological symptomatology and, moreover, tend to exhibit more, and often atypical, physical symptoms. In conclusion, the study supports the presence of a high degree of psychological burden in patients diagnosed with OSAS, regardless of the severity of their symptoms, as determined by the AHI. This comorbidity should be taken into consideration during the clinical assessment of OSAS and for the treatment planning.

[Chronic obstructive pulmonary disease: sense of coherence and family support versus anxiety and depression].

Chronic Obstructive Pulmonary Disease (COPD) is mainly related to smoking habit and is characterized by airflow limitation that is not fully reversible. The airflow limitation is usually both progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases. Worldwide and in Greece, COPD constitutes a major epidemiological issue. Incidence of depression and anxiety is high in the COPD population. Most studies on depression and anxiety in COPD deal with factors that are positively correlated with both of these comorbidities. The aim of our study was to assess whether two variables, sense of coherence (SOC) and perception of family support (FS), are negatively correlated with depressive and anxiety symptoms in outpatients with COPD. According to Aaron Antonovsky, sense of coherence refers to the ability of individuals to make sense of and manage events. Studies in other diseases suggest that sense of family support has a significant impact on the course and outcome of the disease, yet a limited number of reports across literature addresses the role of family support in COPD patients. In our present study one hundred twenty two (98 men and 24 women) outpatients with pure COPD were included. Age and years of education were recorded. Severity of COPD was assessed with spirometry before and after bronchodilation. All patients replied to self- administered questionnaires on depression (Beck Depression Inventory, BDI), anxiety (Spielberger State-Trait Anxiety Scale, STAI), family support (Family Support Scale, FSS-13) and sense of coherence (Sense of Coherence Scale, SOC). According to our results the mean BDI depression score was 11.65 (SD 7.35), mean trait anxiety score was 40.69 (SD 11.19), mean SOC score was 54.62 (SD 7.40) and mean FS score was 64.58 (SD 11.63). Women patients had higher anxiety scores and lower sense of family support compared to men. Significant negative correlations were evidenced between depression and sense of coherence as well as between anxiety and family support. Step-wise multiple linear regression analysis verified the results and quantified the aforementioned correlations. Notably, raising scores in sense of family support by one point reduces anxiety scores by 0.14 points, and increasing sense of coherence scores by one point reduces depression scores by 0.21 points. In sum, our study confirms the presence of high levels of anxiety and depressive symptoms in COPD patients, with females being in a more disadvantaged position as they tend to have higher levels of both. Sense of coherence and family support are both protective psychological factors against the risk of developing anxiety and depressive symptoms in these patients.

[Psychological and psychiatric problems in cancer patients: relationship to the localization of the disease].

Cancer may be localized in a variety of areas in the human body. This localization is associated with significant issues concerning not only therapy and prognosis but also psychological and psychiatric problems that the patient may be confronted with. The psychic impact on the patient is determined to a significant degree by the symbolism the affected organ carries. The symbolic significance of a sick body area triggers emotions and sets in motion self-defence mechanisms. In this way, patients deal with the new psychic reality that cancer creates. Therapeutic choices may include interventions, involving mutilation, which cause disfigurement and major consequences in the body image which result in narcissistic injuries. The phenomenology of anxiety and depressive disorders is connected to the affected body area. The appearance of cancer not only in sexual organs but also in other body areas, may disturb sexual function and therefore lead to sexual disorders. Especially, head and neck are connected with vital functions. This area of the body has had a major impact on psychic reality since early life. Complicated psychic functions have developed in relation to organs of the head and neck. Therefore, localization of cancer in this area leads to individual psychological and psychiatric problems, since eating and breathing are harmed, verbal communication becomes difficult and body image alters. Also, increased incidence of alcohol and nicotine abuse in these patients reflects special aspects of psychic structure and personality. Because of severe somatic symptoms and poor prognosis, lung cancer patients feel hopelessness and helplessness. Patients with gynaecological cancer are confronted with a disease that affects organs like breast and internal female sexual organs associated with femininity, attractiveness and fertility. Dietary habits are often a source of guilt for patients who suffer from cancer of the gastrointestinal tract. Additionally, stomas, as colostomy, affect body image and cause feelings of embarrassment with severe consequences on the patient's sense of wellbeing, his or her daily activities, interpersonal relationships or sexuality. Depressive symptoms often occur in prodromal stages of pancreatic cancer. Depression is a common diagnosis in patients with prostate cancer. Prostatectomy negatively affects patient's self-esteem, because it might be experienced as a threat to his sexual life. Disfigurement is related to skin cancer because of both cancer and surgical procedures. Therefore, it is a challenge for modern psycho-oncology to identify those patients who are vulnerable in developing psychiatric symptoms, to early diagnose anxiety and depression and to use psychotherapeutic interventions targeting individual psychological and psychiatric problems in relation to the localization of disease in the human body.

[Reliability and validity of the Greek version of the Alcohol Use Disorders Identification Test (AUDIT)].

Problems associated with alcohol abuse are recognised by the World Health Organization as a major health issue. Because of the size and severity of the problem, early detection is very important.This requires easy to use and specific tools. One of these is the Alcohol Use Disorders IdentificationTest (AUDIT). AUDIT was translated and back-translated from its original language by two Englishspeaking psychiatrists. The tool contains 10 questions. A score ≥11 is an indication of serious abuse/dependence. In the study, 218 subjects took part: 128 were males and 90 females. From the218 individuals, 109 fulfilled the criteria for alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), and presented requesting admission; 109 subjects were healthy controls. Internal reliability (Cronbach a) was 0.80 for the controls and0.80 for the alcohol dependent individuals. Controls had significantly lower average scores when compared to the alcoholics. The questionnaire's sensitivity for scores >8 was 0.98 and its specificity was 0.94 for the same score. Ιn conclusion, the Greek version of AUDIT has increased internalreliability and validity and is easy to use and can be very useful in detection alcohol problems in sensitive populations.

[Psychological dimension of cancer genetics: Doctor-patient communication].

Cancer is a disease that threatens life and body integrity. A method of cancer prediction is genetic testing, thus the primary detection of individuals who have oncogenes and are at risk of a hereditary cancer. Genetic counseling is the translation of technical information by physicians and the analysis of the problems subsequent to this information, into the therapeutic relationship. Generally, the communication between medical staff and patient must follow certain rules. There are two goals; the physician's comfort when he is dealing with giving news, especially bad news and the maintenance of patient's hope during making decisions for his health and his life. Communication skills focus on emotional reaction and empathy towards the patient.

[Suicide attempts in the General Hospital and warning signs].

Suicide represents a major public health issue and much research is focusing on the prevention and management of suicidal behavior. The present study aims at the assessment of Warning Signs of Suicide. For this purpose, 100 patients admitted for attempted suicide in Sotiria General Hospital have been included in the study. All patients have been examined through a semi-structured psychiatric interview, the somministration of Beck Depression Inventory (BDI) and the assessment of the following Warning Signs: Internalization, Feeling gloomy, Presence of recent trauma in the patient's history, Change of behavior, Fear, Giving gifts, Depression and Aggression. The results showed that 80% of the sample presented at least two warning signs whereas only 10% of the patients had no warning signs. Moreover, a strong correlation was observed between the total score of depression as assessed with the BDI Scale and the number of Warning Signs. Warning Signs are present with a high percentage in patients who attempt suicide and many authors suggest that they should be included in suicide prevention. Therefore, it is important for all mental health clinicians to integrate the assessment of Warning Signs into their practices and to educate both patients and family members to recognize them.

[Psychological and psychiatric problems in cancer patients in the general hospital].

Cancer is the most common cause of death after heart disease. The patient diagnosed with cancer confronts high levels of emotional distress, while he has to make crucial decisions about his treatment. As a life threatening illness, it is a traumatic stressor which triggers overwhelming feelings and affects the patient's functioning. There is a variety of psychological responses. Anger, fear, anxiety, hopelessness attend the diagnosis of cancer. Fifty percent of affected individuals develop psychiatric disorders, such as Stress Response Syndromes like Acute Response Syndromes, Post-traumatic Stress Disorder, Major Depression, Adjustment Disorders, and Delirium. The members of consultation-liaison psychiatry intervene in a wide spectrum of psychiatric complications of cancer. Also, there are patients with major psychiatric disorders such as schizophrenia who develop cancer and the psychiatrist has to give them an understanding of the illness and to facilitate their active participation in the medical treatment. The main purpose is co-operation between consultation liaison psychiatrists and physicians. Psychiatrists make efforts to promote a better understanding of schizophrenia among physicians and to fight the stigma attached to the disease. The risk of suicide is higher in cancer patients, than in general population and the identification of patients at increased risk of suicide among affected individuals such as those with major depression, alcohol abusers, uncontrolled pain, advanced illness is a very important step in suicide prevention. When the end of life is approaching, psychiatrists have to face physical problems, psychological symptoms and issues of existence, which pose special challenges for the patient. The psychiatrist has to help him to reduce the psychological pain and to encourage his family to listen to his wishes. The consultationliaison psychiatrists intervene at every stage of cancer from the prevention and the preclinical cancer, to palliative care and end-of-life, with diagnosis and effective therapy.

Quetiapine monotherapy in bipolar disorder: Two years maintenance treatment in an elderly woman.

Queatiapine has been used in bipolar mania and most recently in bipolar depression with good results. However its use in maintenance treatment has not been established yet. A case of an elderly woman suffering from bipolar disorder and diabetes mellitus (type II) is presented. The use of quetiapine as a monotherapy (300 mg/day) was efficient and safe and proved to be a good treatment in mood stabilization for two years.

Changes in dopamine receptor responsivity during alcohol detoxification may predict relapse.

In the search for clinical and biological variables that may predict relapse of alcohol dependent patients after detoxification, we followed up for 1 year male patients that had undergone successful detoxification. The patients had been tested earlier during their usual alcohol consumption and immediately after detoxification for the responsivity of D2 dopamine receptors (as measured by the increases in prolactin plasma levels caused by intramuscular administration of 5 mg of the dopamine receptor blocker haloperidol). Of the 18 patients, eight had not consumed alcohol for more than 6 months, and ten had relapsed within 6 months. Comparison of the clinical and neuroendocrine data for the two subgroups revealed no significant differences in age, amount of alcohol consumed during alcohol abuse, score in the Beck Depression Inventory, score in the Brief Michigan Alcoholism Screening Test, or prolactin responses to haloperidol before detoxification. In patients who relapsed, the duration of alcoholism was marginally shorter (P=0.055). Patients who did not relapse had significantly higher (P=0.003) prolactin responses to haloperidol in the test performed after detoxification as compared with patients who did relapse, and their responses were similar to those of a group of healthy male subjects. The results show that the increase in dopamine receptor responsivity that occurs after detoxification is a favourable factor for non-relapse; it may reflect recovery from down-regulation of the dopaminergic reward system caused by alcohol consumption.

Dopamine receptor responsivity in alcoholic patients before and after detoxification.

OBJECTIVE: To assess central dopamine receptor responsivity in alcoholic patients during their usual alcohol consumption and after detoxification. METHOD: Plasma prolactin levels were measured at 0, 30, 60, and 90 min after administration of 5 mg haloperidol i.m. in 21 hospitalized male alcoholic patients during usual alcohol consumption, and 13 days later (mean, range 7-17 days), after detoxification. The test was also performed in seven healthy male volunteers. The patterns of prolactin responses were compared using repeated measures analysis of variance. RESULTS: The prolactin responses to haloperidol increased significantly after detoxification compared to those during usual alcohol consumption (state x time interaction P < 0.01; planned comparisons for times 0 and 90 min between states P = 0.03). Compared to controls, the responses of the patients before detoxification were lower (group-time interaction P = 0.001), and the difference was not significant after detoxification (P = 0.19). The magnitude of plasma prolactin (PRL) responses were not related to duration of alcohol abuse, score in the Brief Michigan Alcoholism Screening Test (BMAST) scale, or family history of alcoholism. CONCLUSIONS: Alcohol detoxification is accompanied by a normalization of the low responsivity of central dopaminergic receptors during alcohol abuse. The data support the hypothesis of a participation of the central dopaminergic system in alcohol dependence.

Platelet monoamine oxidase, plasma dopamine beta-hydroxylase activity, dementia and family history of alcoholism in chronic alcoholics.

The authors measured platelet monoamine oxidase (MAO) activity and plasma dopamine beta-hydroxylase activity in 36 male chronic alcoholics during a period of non-abstinence, and in 29 normal controls. The influence of family history, dementia, chronicity of drinking and liver injury on the enzyme activities was also examined by multiple regression analysis. Platelet MAO was significantly lower in the alcoholic group. Both enzyme activities were negatively related to the presence of dementia, while low MAO activity was associated with positive family history (parents, sibs) of alcoholism.

Plasma cyclic AMP in non-abstinent chronic alcoholics. Relation to clinical parameters.

Plasma cyclic AMP levels were determined in a group of 36 male chronic alcoholics during a period of their usual alcohol intake and compared to 29 normal controls. Significantly lower values (P less than 0.005) were found in the patient group. The possible influence of age, chronicity of drinking, family history of alcoholism, dementia and liver injury on plasma cAMP levels was examined by multiple regression analysis. No influence of those factors could be established except that demented alcoholics showed a trend toward higher levels than a non-demented subgroup. The role of reduced beta-adrenergic receptor activity during chronic alcohol ingestion is discussed in relation to the above findings.

Normal testosterone plasma levels in non-abstinent alcoholics.

Testosterone (T), prolactin (PRL), and luteinizing hormone (LH) levels were estimated in plasma of 32 male chronic alcoholics during a period of their usual alcohol consumption and compared to the values of 32 age-matched controls. T levels were not different from normals, while both PRL and LH were significantly elevated. The subgroup of patients with severe liver injury (n = 11) showed elevated PRL (2P less than 0.001), but normal LH and T, while patients with normal hepatic function (n = 21) showed normal PRL levels, elevated LH, and a tendency to elevated T levels.

Platelet monoamine oxidase and plasma dopamine-beta-hydroxylase activities in non-abstinent chronic alcoholics. Relation to clinical parameters.

Platelet monoamine oxidase (MAO) and plasma dopamine-beta-hydroxylase (DBH) activities were determined in 27 male non-abstinent chronic alcoholics. Compared to 24 normals, no significant difference in both enzyme activities was found. Alcoholics with at least one alcoholic first degree relative had a trend toward lower platelet MAO activity compared to those without such a history. Matched pair analysis showed that alcoholics of the former subgroup had significantly lower MAO activity than controls. Demented alcoholics had significantly reduced plasma DBH activity compared with the non-demented subgroup and with age, and sex, matched controls.

Delusional depression: phenomenology and response to treatment.

In this retrospective study demographic and clinical characteristics, personality traits, family psychiatric history and response to treatment were compared in 55 delusional and 40 nondelusional hospitalized patients who met DSM-III criteria for major depression. Male delusional depressives had a greater frequency of delusional ideas at the index episode than female delusionals. Delusional depressives had a greater frequency of family history for alcoholism, a smaller frequency of previous depressive episodes and tended to respond more favorably to treatment with electroconvulsive therapy or tricyclic antidepressants combined with neuroleptics than to antidepressants alone. The findings and the implications arising from them are discussed.
