Posttraumatic stress disorder and alcohol dependence: Does order of onset make a difference?

Posttraumatic stress disorder (PTSD) and alcohol dependence (AD) are frequently comorbid and the order in which they develop may affect the clinical presentation and response to treatment. This study compared 73 treatment-seeking participants who developed PTSD prior to developing AD (“PTSD-first”) with 64 participants who developed AD prior to developing PTSD (“AD-first”) on demographics, clinical presentation, and response to treatment for PTSD and AD. All participants received BRENDA, a medication management and motivational enhancement intervention and were randomly assigned to either prolonged exposure (PE) for PTSD plus BRENDA or BRENDA alone and to either naltrexone (NAL) for AD or placebo (PBO). Results showed that participants with AD-first were more likely to report low income, meet criteria for antisocial or borderline personality disorder, report an index trauma of physical assault, compared to those with PTSD-first. Conversely, participants with PTSD-first were more likely to report an index trauma of sexual assault or a combat experience. Notably, no group differences were observed in treatment outcome despite some differences in clinical presentation.     

How many cravings? Pharmacological aspects of craving treatment in alcohol addiction: a review

In the last decade, craving has increasingly been considered an important target for the treatment of patients with alcohol problems, and several drugs able to interfere with the neurotransmitters involved in craving mechanisms have been experimented. However, different subtypes of patients could have different mechanisms at the basis of alcohol craving. In this review, the main drugs currently used in the treatment of patients with alcohol problems are described. A hypothesis of pharmacological treatment of the different types of craving is also discussed.     

Opioids in chronic pain management: is there a significant risk of addiction?

In the last decade there has been significant controversy about the appropriateness, efficacy, safety, and wisdom of treating chronic pain patients (CPPs) with opioids. Arguments against their use have included concerns about tolerance, dependence, addiction, persistent side effects, and interference with physical or psychosocial functioning. However, considerable experience and research with long-term cancer pain treatment suggests that in appropriately selected patients, opioids have a low morbidity, and a low addiction potential, and in addition to the primary analgesic action, can facilitate reduction in suffering, enhance functional activity level, and improve quality of life without significant risk of addictive behaviors. Some patients, however, are at risk. Risk factors for addiction are discussed in this article.     

Is the effect of alcohol on risk of stroke confined to highly stressed persons?

BACKGROUND: Psychological stress and alcohol are both suggested as risk factors for stroke. Further, there appears to be a close relation between stress and alcohol consumption. Several experimental studies have found alcohol consumption to reduce the immediate effects of stress in a laboratory setting. We aimed to examine whether the association between alcohol and stroke depends on level of self-reported stress in a large prospective cohort. METHODS: The 5,373 men and 6,723 women participating in the second examination of the Copenhagen City Heart Study in 1981-1983 were asked at baseline about their self-reported level of stress and their weekly alcohol consumption. The participants were followed-up until 31st of December 1997 during which 880 first ever stroke events occurred. Data were analysed by means of Cox regression modelling. RESULTS: At a high stress level, weekly total consumption of 1-14 units of alcohol compared with no consumption seemed associated with a lower risk of stroke (adjusted RR: 0.57, 95% CI: 0.31-1.07). At lower stress levels, no clear associations were observed. Regarding subtypes, self-reported stress appeared only to modify the association between alcohol intake and ischaemic stroke events. Regarding specific types of alcoholic beverages, self-reported stress only modified the associations for intake of beer and wine. CONCLUSIONS: This study indicates that the apparent lower risk of stroke associated with moderate alcohol consumption is confined to a group of highly stressed persons. It is suggested that alcohol consumption may play a role in reducing the risk of stroke by modifying the physiological or psychological stress response.     

Early onset of cardiomyopathy and primary prevention of sudden death in X-linked Emery–Dreifuss muscular dystrophy

We report the case of 14-year-old boy with X-linked Emery–Dreifuss muscular dystrophy who developed sick sinus syndrome and required placement of an implantable intracardiac cardioverter-defibrillator (ICD) to prevent sudden death. He demonstrated no significant risk factors for sudden death such as depressed left ventricular ejection fraction, or spontaneous or inducible ventricular tachycardia. One month after implantation, the patient experienced one appropriate ICD discharge.     

Cryptogenic Late‐onset Epileptic Spasms: An Overlooked Syndrome of Early Childhood?

PURPOSE: Few reports detailing late-onset epileptic spasms have been published. To determine whether this condition merely represents a late variant of classic West syndrome or exhibits specific features distinct from the latter and related to a later stage of brain maturation, we analyzed the whole population with this specific seizure type, excluding symptomatic cases to avoid the effect of brain lesion. METHODS: We reviewed the files of the 56 children evaluated for epileptic spasms in clusters having begun at age 12 months or later and analyzed clinical and video-EEG data of the 22 patients (4-17 years; mean, 8.5 years) without obvious cause. RESULTS: Interictal EEG did not show classic hypsarrhythmia. A temporal or temporofrontal slow wave and/or spike focus could be identified in all cases. Twelve children showed spasms with a tonic component. Ictal EEG revealed generalized high-voltage slow wave followed by diffuse voltage attenuation with superimposed fast activity. All children also exhibited other types of recorded seizures consisting of bursts of spike-waves with temporofrontal predominance, reminiscent of "atypical absences." In contrast with the occurrence of tonic components within a cluster of spasms, no tonic seizure stricto sensu was recorded or reported by the caregivers. In 10 children, treatment (two vigabatrin, seven hydrocortisone, one adrenocorticotropic hormone) achieved complete cessation of seizures and disappearance of focal EEG anomalies, but spasms persisted in 12 children. CONCLUSIONS: The cryptogenic group in our series without recognized cause and temporal or temporofrontal EEG anomalies seems to represent a type of epileptic encephalopathy intermediary between West and Lennox-Gastaut syndromes, in terms of seizure types and interictal EEG, and could correspond to dysfunction of the maturation process of the temporal lobe, possibly due to an undisclosed lesion.

Early detection and treatment of schizophrenia: how early?

OBJECTIVE: Whereas early detection and therapy of schizophrenic psychoses until some time ago concentrated on frank schizophrenia, during the last years some centres have also started to treat patients even before a clear diagnosis could be established. This paper attempts to discuss if and when this is justified in the light of recent research. METHOD: Mini review of literature. RESULTS: The rationale for early detection and treatment of schizophrenia is based on several observations: diagnosis and treatment of schizophrenia are often seriously delayed. Consequences of the disease are severe already in the early undiagnosed phase of the disorder and early treatment seems to improve the course of the disease. It can therefore be stated quite safely that patients should be treated as early as possible. However, the question of how early has not been sufficiently answered up to now. CONCLUSION: We are at the moment in an ethical dilemma between either diagnosing and treating this disorder too late or too early. The only way and prerequisite for solving this dilemma is a more reliable identification of individuals at risk and the beginning disease process.     

What causes the onset of psychosis?

It has become increasingly clear that the simple neurodevelopmental model fails to explain many aspects of schizophrenia including the timing of the onset, and the nature of the abnormal perceptions. Furthermore, we do not know why some members of the general population have anomalous experiences but remain well, while others enter the prodrome of psychosis, and a minority progress to frank schizophrenia. We suggest that genes or developmental damage result in individuals vulnerable to dopamine deregulation. In contemporary society, this is often compounded by abuse of drugs such as amphetamines and cannabis, which then propel the individual into a state of dopamine-induced misinterpretation of the environment. Certain types of social adversity such as migration and social isolation, as well as affective change can also contribute to this. Thereafter, biased cognitive appraisal processes result in delusional interpretation of the abnormal perceptual experiences. Thus, a plausible model of the onset of psychosis needs to draw not only on neuroscience, but also on the insights of social psychiatry and cognitive psychology.     

Does addiction to antidepressants exist? About a case of one addiction to tianeptine

We report on a tianeptine dependence lasting for eighteen months in a 42 year old patient. The patient had a previous history of addiction to opiates, amineptine, coca?ne and alcohol. He also had a family history of addiction to alcohol and opiates. Tianeptine was prescribed for a major depressive disorder. The patient alleged a "flash sensation" like with heroin since the very first doses with a physical and psychological well-being sensation, better psychomotor performances and transient mood elation. His addiction to tianeptine was immediate and heavy. The positive reinforcement faded away after one month and a total dependance took over, with physical and psychological withdrawal symptoms when doses were not renewed. After two months of treatment, the daily consumption of tianeptine was of 90 tablets. The patient was hospitalised to treat both the addiction to tianeptine and the ongoing major depressive disorder. He was taking 240 tablets daily. In the literature, reports of addictions to antidepressants are scarce and most of them involve agents with amphetamine-like properties, including amineptine and tranylcypromine. Other reports involving other antidepressant agents, including amitriptyline, fluoxetine and tianeptine remain exceptional. Addictions to antidepressants almost exclusively concern patients with a diagnosis of personality disorder and a previous history of drug or alcohol abuse and who are treated for a depressive disorder. Tianeptine, which is devoid of any psychostimulating effect in human, does not seem to have addictive properties apart from the reports of scarce cases.
