  • Interview with Pierre Pichot
    PSYCHOPHARMACOLOGY AND THE HISTORY OF PSYCHIATRY PIERRE PICHOT Could we begin with your recollections of the 1955 Paris meeting, which was effectively the first world wide meeting on chlorpromazine. The meeting was organised in Paris by Jean Delay. It was supported by Specia, the pharmaceutical firm which had produced chlorpromazine, which was a branch of the Rhone Poulenc Group. For the first time people engaged in what was called psychopharmacology came together. They came from many countries, including the United States. The efficacy of the drug and the mechanism of action were discussed. However, at that time the biochemistry of the brain, as it exists now, was unknown. It was only at the beginning of the 60s, that we began to speak of the role of the neurotransmitters in the action of both neuroleptic drugs and antidepressants and of their potential abnormalities in the disease process. So in practice 1955 was only a meeting on therapy with chlorpromazine. I have always been very much impressed by the fact that chlorpromazine, which had been introduced only 3 years before, was already used all over the world. Theoretical ideas take usually a very long time to travel from one country to another, and sometimes they never make it. I quote always, the case of Karl Jaspers’ General Psychopathology, which is considered in the German speaking world as one of the basic books of psychiatry. This was published in 1913 but appeared in English translation only in 1963, 50 years later and, even then, a paper published in the American Journal of Psychiatry wrote ingenuously that, until this publication, many psychiatrists in the United States had not realised that Jaspers was not only a philosopher, but also a psychiatrist.

  • The Challenge of Managing Wounds in the Injecting Drug- Dependent Patient
    Clinical PRACTICEClinical DEVELOPMENT REVIEW The challenge of managing wounds in the injecting drug- dependent patient Managing wounds in the patient who injects drugs is complex for healthcare professionals. As with the non- drug taking population, the problems of mobility, odour from the wound, social limitation and pain still occur, but fears of discrimination may lead to reluctance to seek medical intervention, potentially leading to slower recovery and chronicity. This article focuses on the problems encountered by injecting drug users, a group that can suffer significant wound care issues, including infection, wound abscess and fistula formation, along with other management problems, such as a reciprocal mistrust of healthcare professionals.

  • Predictors of Skin and Soft Tissue Infections Among Sample of Rural Residents Who Inject Drugs
    Baltes et al. Harm Reduct J (2020) 17:96 https://doi.org/10.1186/s12954-020-00447-3 RESEARCH Open Access Predictors of skin and soft tissue infections among sample of rural residents who inject drugs Amelia Baltes1* , Wajiha Akhtar2, Jen Birstler3, Heidi Olson‑Streed4, Kellene Eagen1, David Seal5, Ryan Westergaard2 and Randall Brown1 Abstract Introduction: Skin and soft tissue infections (SSTIs) are among the leading causes of morbidity and mortality for people who inject drugs (PWID). Studies demonstrate that certain injection practices correlate with SSTI incidence among PWID. The opioid epidemic in the USA has particularly afected rural communities, where access to preven‑ tion and treatment presents unique challenges. This study aims to estimate unsafe injection practices among rural‑ dwelling PWID; assess treatments utilized for injection related SSTIs; and gather data to help reduce the overall risk of injection‑related SSTIs. Methods: Thirteen questions specifc to SSTIs and injection practices were added to a larger study assessing unmet health care needs among PWID and were administered at six syringe exchange programs in rural Wisconsin between May and July 2019. SSTI history prevalence was estimated based on infections reported within one‑year prior of response and was compared to self‑reported demographics and injection practices. Results: Eighty responses were collected and analyzed. Respondents were white (77.5%), males (60%), between the ages 30 and 39 (42.5%), and have a high school diploma or GED (38.75%). The majority of respondents (77.5%) reported no history of SSTI within the year prior to survey response. Females were over three times more likely to report SSTI history (OR 3.07, p 0.038) compared to males.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Many patients with schizophrenia show cognitive impairment. There is evidence that, beyond a certain dose of antipsychotic medication, the antipsychotic daily dose (ADD) may impair cognitive performance. Parallel to their D2 receptor antagonism, many antipsychotics show a significant binding affinity to cholinergic muscarinic receptors. Pharmacological treatment with a high anticholinergic daily dose (CDD) significantly impairs attention and memory performance. To examine the relationships between individual cognitive performance and ADD and/or CDD, we conducted a retrospective record-based analysis of a sample of = 104 in patients with a diagnosis of schizophrenia, all of whom had completed a comprehensive neuropsychological test battery. To calculate the individual ADD and CDD, the medication at the time of testing was converted according to equivalence models.

  • Alcohol and Drug Education/Sun Protection
    HEALTH INITIATIVE LUNCH AND LEARN III: ALCOHOL AND DRUG EDUCATION/SUN PROTECTION K A T I E L. HOWE: HEALTH EDUCATOR MARK FINK: ASSISTANT DIRECTOR, FITNESS T H U R S D A Y , M A R C H 6 , 2014 CAMPUS LIFE CENTER QUIET ROOM 1 2 : 0 0 - 12:30 P.M. OVERVIEW • Alcohol Education: • Drinking Responsibly • Binge Drinking • Alcohol Poisoning • Drug Education: • Recreational Drugs • Prescription Drugs • Sun Protection: • Vitamin D • Skin Cancer • Sun Screens ALCOHOL EDUCATION • Not all drinks are equal!! • The alcohol content differs among each type of drink. Beer for example can range from 4% to upwards of 20% (high gravity). • Blood Alcohol Content (BAC): The percentage of alcohol in the blood. The greater percentage of alcohol a drink contains, the faster a person’s BAC will rise. DRINKING RESPONSIBLY • Abstain from drinking until you are of legal age. • Always practice moderation. • 2 drinks for men, 1 drink for women. • Always appoint a designated driver. • Never pressure anyone to drink. • Be a role model. • Nutrition • 7 calories/gram of Alcohol • Most alcoholic beverages are approximately 125-150 calories, however once you begin mixing with soda, juice, etc. the calories begin to pile on. If you choose to drink liquor try mixing with water or club soda. Also add extra ice cubes or keep it on the rock. This dilutes the cocktail allowing you to sip on the drink longer, decreasing the number of drinks consumed and also increases water intake. BINGE DRINKING/ALCOHOL POISONING Binge Drinking (Episodic Excessive Drinking) Alcohol Poisoning • Men: 5 or more drinks.
