Severe beta-blocker overdose in a 65-year-old female

Introduction: Population of people over 65 years old is one of the groups of the greatest risk of suicide attempt. In this age range the highest suicide rate that results in death is observed. Metabolism alterations and co-morbidities development with age may play major role in increasing suicide rate. Accidental and intentional drug over-ingestions are more common for people with numerous prescriptions and comorbid conditions. Overdose in such patients can pose great threat to patients life. Aim of the study: The purpose of this study is to depict course of β-adrenolitics and benzodiazpines poisoning on the base of case report. Materials and methods: The analysis of the patient's medical history and the review of available literature in the PubMed and Google Scholar databases. Results: The 65-year-old female, was brought by emergency medical services to the Toxicology Clinic due severe drug poisoning. Upon admission patient was unconscious, intubated, on ventilator, in overall severe condition. She presented symptoms of circulatory insufficiency. History revealed overdose of β-adrenolitics and benzodiazepines. The application of proper pharmacological treatment and heart pacing resulted in gradual improvement of patients condition. After one-week stay she was discharged home in good condition. Conclusions: Course of β-adrenolitics poisoning with addition of benzodiazepines poses great threat, especially when one suffers from numerous comorbidities. Therefore, due to wider availability of drugs and rising number of suicide attempts, as well as events of medication errors, it is crucial to be aware of elder people problems and prevent such situations

New psychoactive substances abuse and its clinical consequences - the case report

Introduction: The meteoric rise of new psychoactive substances' use has been a public health problem for at least few years. Their presence was noticed by EU authorities around 2005. First cases of NPS poisoning in Poland appeared shortly thereafter, in 2008. Due to great variety of used substances and lack of information about them, precise diagnosis and targeted treatment remain a significant problem. Hereby, we present a patient with multi-drug poisoning related to NPS abuse and discuss new psychoactive substances that are often found in such cases. Aim of study: To discuss most common new psychoactive substances and their health effects on the basis of the case report Results: A 28-year old patient was admitted to the Department of Toxicology and Cardiology with symptoms suggesting acute intoxication with psychoactive substances. The patient had a history of drug abuse. A few pouches containing unidentified psychoactive substances were found near the patient. On admission, his condition was serious- he was unconscious and required mechanical ventilation. Tachycardia and aspiration pneumonia were present as well.The applied therapy focused on restoring acid- base homeostasis, electrolyte balance and mitigating toxic influence of detected drugs, with preventive antibiotic administration used as well. His general and psychological condition improved with treatment, and he was discharged from the department after ten days, with continuation of the therapy in ambulatory setting. Conclusions: An increasing amount of patients present cases of polysubstance abuse, whose treatment may prove especially difficult. Such cases require extensive therapy to prevent debilitating complications. A focus on drug regulation and patient education could diminish the number of such cases in the future

The potential of cannabinoids in the treatment of lung cancer

Introduction: Lung cancer is the number-one cause of death due to neoplasms worldwide. The 5-year overall survival rate is only 22%. In advanced stages, the therapeutic options are limited to chemotherapy, radiotherapy, molecularly targeted therapy and immunotherapy. Phytocannabinoids, the components of Cannabis sativa, their synthetic derivatives and endogenous cannabinoids have demonstrated anticancer activity in various common cancers - breast, prostate, colorectal and lung cancers, among others. The aim of this review was to assess the potential value of cannabinoids in the treatment of lung cancer. State of knowledge: The majority of preclinical studies demonstrates that cannabinoids inhibit lung cancer cell viability both in vitro and in vivo. The main mechanism of anticancer  activity is the induction of apoptosis, triggered by activation of CB1, CB2 and TRPV1 receptors or independently via other pathways. Cannabinoids influence the components of the tumour microenvironment - cancer associated fibroblasts, macrophages and lymphokine-activated-killer cells. Cannabinoids alter leukocyte infiltration into anti-cancer proportions, inhibit expression of EGFR and PAI-1 and increase the expression of TIMP-1. As a result they induce cytotoxicity, decrease proliferation, migration and invasive potential of lung cancer cells, suppress angiogenesis and metastasis forming. Patients with advanced lung cancer may also benefit from analgesic, antiemetic and appetite improving properties of cannabinoids. Summary: Cannabinoids can be a supplementary agent in systemic anticancer therapeutic regimen in the future. The exact mechanisms of action, specific doses in anticancer treatment, routes of administration and interactions with other anticancer drugs has yet to be determined. Thus the clinical studies on cannabinoids in lung cancer should be performed in the future

Risk factors for postoperative infectious complications after RIRS treatment of kidney and ureteral stones

Abstract Introduction and aim of the study: Urolithiasis is a disease involving the formation of deposits in the lumen of the urinary tract. The continued development of minimally invasive treatment methods allows for more effective treatment with greater operator comfort and less risk to the patient. It has been concluded that retrograde intrarenal surgery (RIRS) is superior to other therapeutic methods in many respects. The aim of this study is to review the available studies and publications and to identify potential complications following treatment of kidney and ureteral stones by RIRS, with a particular focus on infectious complications and their risk factors.   Method and materials: We reviewed the literature available on PubMed and Google Scholar, using the words 'urolithiasis'; 'urolithiasis treatment'; 'retrograde intrarenal surgery'; 'infectious complications of retrograde intrarenal surgery'.   Results: Among the risk factors associated with infectious complications after RIRS, long duration of surgery, recent positive urine culture, urinary tract infections or antibiotic use, purulent urine, urinary nitrites, obstructed access through the ureter, struvite stones, co-morbidities play a special role.   Conclusions: Among the complications of surgical treatment of nephrolithiasis and ureteral stones by RIRS, infectious complications are of particular concern. In view of the knowledge of their risk factors, preventive measures should include limiting the duration of surgery, possible antibiotic therapy and considering the use of a larger diameter UAS. This is especially true for patients with abnormal urine results, struvite stones, a history of urinary tract infection or predisposing comorbidities.   Key words: Urolithiasis; Kidney Calculi; Retrograde Intrarenal Surgery; Urolithiasis infection

Cannabidiol Interacts Antagonistically with Cisplatin and Additively with Mitoxantrone in Various Melanoma Cell Lines—An Isobolographic Analysis

The medical application of cannabidiol (CBD) has been gathering increasing attention in recent years. This non-psychotropic cannabis-derived compound possesses antiepileptic, antipsychotic, anti-inflammatory and anxiolytic properties. Recent studies report that it also exerts antineoplastic effects in multiple types of cancers, including melanoma. In this in vitro study we tried to reveal the anticancer properties of CBD in malignant melanoma cell lines (SK-MEL 28, A375, FM55P and FM55M2) administered alone, as well as in combination with mitoxantrone (MTX) or cisplatin (CDDP). The effects of CBD on the viability of melanoma cells were measured by the MTT assay; cytotoxicity was determined in the LDH test and proliferation in the BrdU test. Moreover, the safety of CBD was tested in human keratinocytes (HaCaT) in LDH and MTT tests. Results indicate that CBD reduces the viability and proliferation of melanoma-malignant cells and exerts additive interactions with MTX. Unfortunately, CBD produced antagonistic interaction when combined with CDDP. CBD does not cause significant cytotoxicity in HaCaT cell line. In conclusion, CBD may be considered as a part of melanoma multi-drug therapy when combined with MTX. A special attention should be paid to the combination of CBD with CDDP due to the antagonistic interaction observed in the studied malignant melanoma cell lines
