BACKGROUND: Human immunodeficiency virus (HIV) is no longer considered a contraindication for kidney transplantation (KT). KT management in HIV patients is a complex process with challenges, such as drug interactions between immunosuppression and antiretroviral (ARV) therapy. In our country, no KT has been performed thus far in this category of patients.
METHODS: We present the case of a 29-year-old female patient with HIV and end-stage renal disease (ESRD) who performed a KT from a related living donor in March 2022. KT immediate evolution was favorable. No transplant-related complications were reported. HIV viral load remained undetectable and CD4+ T cells were constantly > 500 cell/ μL, during the 18 months of follow-up. The main challenge in our case was the drug interaction between the protease inhibitor-based regimen and tacrolimus. This led to tacrolimus overdose, and, subsequently, change in ARV therapy. ARV switching was performed on a regimen based on integrase inhibitor and nucleoside reverse transcriptase inhibitors. After the ARV change, the therapeutic level of tacrolimus was easily reached and maintained. Kidney graft function remained normal during follow-up, despite tacrolimus overexposure, and no rejection or anti-HLA antibodies were observed. Another challenge was related to the donor\'s hepatitis C virus status (positive antibodies, negative nucleic acid test). The recipient did not develop seroconversion or detectable viremia at 3-, 6-, 12- and 18-months post-KT.
CONCLUSIONS: We reported the first case of a successful KT in an ESRD patient with HIV in Romania, in whom the post-transplant evolution was favorable.

Puffy hand syndrome occurs in addicts who have injected drugs either intravenously, intradermally, or subcutaneously. It usually presents as bilateral reversible pitting edema of the hands; less frequently, it occurs unilaterally. The forearms and arms may also be affected. The onset of puffy hand syndrome can occur while the patient is still injecting drugs; however, it can initially appear several years after injection of the drug has been discontinued. Infection with hepatitis C is a common comorbidity. A 47-year-old man is described who had a 20-year history of injecting methylamphetamine only into his non-dominant left arm, forearm, and hand and experienced his second episode of unilateral puffy hand syndrome four years after discontinuing injecting the drug and three years after his initial episode; he also had hepatitis C infection. He presented with erythema and pitting edema of his left hand and forearm. Cellulitis was initially suspected, and he was admitted to the hospital for intravenous antibiotics; all cultures were negative for pathogens. The erythema and swelling resolved after five days of therapy. Puffy hand syndrome has been associated with various drugs; it has also been observed to occur in women during pregnancy and occasionally associated with acrocyanosis. The diagnosis is often not originally entertained by the clinician; the condition is often initially treated empirically as an infection. Serologic evaluation is typically negative for rheumatologic diseases, such as systemic lupus erythematosus and scleroderma, and cultures of the skin and blood are usually negative for pathogens. Radiologic assessment (such as roentgenograms, ultrasound to rule out venous thrombosis, computed tomography, magnetic resonance imaging, venogram, and lymphangiogram) may be performed, to exclude other conditions. Skin biopsy of the affected edematous hand occasionally demonstrates granulomatous inflammation and foreign bodies (suggestive of starch or injection additives) in the dermis. The edema for some of the patients with puffy hand syndrome was successfully treated with daily bandaging with compression stockings. The pathogenesis of puffy hand syndrome is considered to be multifactorial: damage to the veins, injury to the lymphatic system, and direct toxicity of the injectable drugs to the vascular structures.

Acenocoumarol is one of the most common drugs used as a part of the management of patients undergoing cardiac surgery. Linezolid, on the other hand, is an antibiotic prescribed post-operatively. Reports of any interaction between the two are very few. Here, we are presenting four case reports of patients admitted to the Cardio Thoracic and Vascular Surgery Department of a tertiary healthcare center in North East India. Drug-drug interactions can lead to long-term and life-threatening effects, and also hamper the management of patients post-operatively. Due to the limited literature, assessing such interactions is difficult. The cases reported here were treated with fresh frozen plasma, and the patients responded well to the treatment and were discharged without further complications.

BACKGROUND: Online pharmacies are used less than other e-commerce sites in Germany. Shopping behavior does not correspond to consumption behavior, as online purchases are predominantly made for over-the-counter (OTC) medications.
OBJECTIVE: The objective of this study was to understand the purchasing experiences of online pharmacy customers in terms of critical factors for online pharmacy adoption.
METHODS: This study examined the perceived risk, perceived trust, and emotions related to purchasing medications online and, consequently, the purchase intention toward online pharmacies. In a within-subjects design (N=37 participants), 2 German online pharmacies with different perceptions of risk and trust were investigated for their main business, namely OTC and prescription drugs. The results of a preliminary study led to 1 online pharmacy with high and 1 with significantly low self-reported risk by the prestudy sample. Emotions were measured with a multimethod approach during and after the purchase situation as follows: (1) neural evaluation processes using functional near-infrared spectroscopy, (2) the automated direct motor response during the use of the online pharmacy via facial expression analysis (FaceReader), and (3) subjective evaluations through self-reports. Following the shopping experiences at both pharmacies for both product types, risk, trust, and purchase intention toward the pharmacies were assessed using self-assessments.
RESULTS: The 2 online pharmacies were rated differently in terms of risk, trust, emotions, and purchase intention. The high-risk pharmacy was also perceived as having lower trust and vice versa. Significantly stronger negative emotional expressions on customers\' faces and different neural activations in the ventromedial prefrontal cortex and dorsomedial prefrontal cortex were measured when purchasing prescription drugs from the high-risk pharmacy than from the low-risk pharmacy, combined with OTC medications. In line with this, customers\' self-ratings indicated higher negative emotions for the high-risk pharmacy and lower negative emotions for the low-risk pharmacy. Moreover, the ratings showed lower purchase intention for the high-risk pharmacy.
CONCLUSIONS: Using multimethod measurements, we showed that the preceding neural activation and subsequent verbal evaluation of online pharmacies are reflected in the customers\' immediate emotional facial expressions. High-risk online pharmacies and prescription drugs lead to stronger negative emotional facial expressions and trigger neural evaluation processes that imply perceived loss. Low-risk online pharmacies and OTC medications lead to weaker negative emotional facial expressions and trigger neural evaluation processes that signify certainty and perceived reward. The results may provide an explanation for why OTC medications are purchased online more frequently than prescription medications.

BACKGROUND: This case series describes the safety and efficacy of superselective intra-arterial (IA) cerebral infusion of teniposide for the treatment of patients with glioma, to provide new ideas and methods for the treatment of high grade gliomas.
METHODS: 12 patients with glioma who were previously treated with standard therapy were treated with superselective IA cerebral infusion of teniposide. Patients received at least two cycles of treatment (one cycle: 150 mg/time, used for 1 day, repeated at 28 day intervals) after blood-brain barrier disruption. Patients received individualized treatment on the tumor location. The ophthalmic artery was bypassed during the super-selective arterial infusion.
RESULTS: No significant differences in biochemical indexes and Karnofsky performance status (KPS) score were observed before and after treatment, and no evident adverse events occurred (P>0.05). In a recent response evaluation (August 2023), two (8%) patients presented with a complete response (16.7%), four had a partial response (33.3%), four had stable disease (33.3%), and two showed progressive disease (16.7%). The overall response rate and disease control rate were 50.0% and 83.3%, respectively. In addition, we described the detailed course of treatment in two patients. Case No 1 (recurrent tumor) and case No 2 (primary tumor) received six and three cycles of teniposide infusion, respectively. After treatment, the tumors of the patients were significantly reduced without evident adverse effects.
CONCLUSIONS: This small series suggests that superselective IA cerebral infusion of teniposide may be a safe and effective therapy in the multimodal treatment of malignant glioma and warrants further study in larger prospective investigations.

The evaluation of the skin of the decedent is an essential component of the assessment by the forensic pathologist or the medical examiner. Age-associated cutaneous changes, primary diseases of the skin, and systemic conditions with mucocutaneous manifestations can be present. Importantly, several dermatoses can be misinterpreted for traumatic injuries; specifically, adverse reactions to medications can mimic assault, burns, elder abuse, and mutilation or torture. A male with corticosteroid-induced dermatitis mimicking an acute burn is described. A female with thalidomide embryopathy is reported with extensive deformities of her hands and feet with multiple absent digits mimicking a severe injury resulting from mutilation or torture. Another female is described who had hydroxychloroquine-associated hyperpigmentation; her physician misinterpreted the cutaneous hyperpigmentation as bruises and notified Adult Protective Services. Reactions to medications can also mimic assault, burns, and elder abuse. Drug reaction with eosinophilia and systemic symptoms (particularly when associated with phenytoin) can mimic assault. Albeit rarely, the antihypertensive irbesartan can result in dramatic edema of the face and eyelids similar to that observed following an assault. Drug-induced erythema multiforme can mimic a localized burn, and Stevens-Johnson syndrome or vancomycin infusion reaction can mimic an extensive burn. Several medications can mimic bruising observed in victims of elder abuse; they include amiodarone, arsenic, and tetracyclines (such as minocycline and doxycycline). In summary, an important aspect of the forensic evaluation during an autopsy includes a complete cutaneous examination; to aid in differentiating medication-associated dermatoses that can mimic traumatic injury, the evaluation of the decedent by a forensic dermatologist may be helpful to establish the etiology of observed skin changes.

BACKGROUND: The incidence of early-onset colorectal cancer (EOCRC) rose abruptly in the mid 1990s, is continuing to increase, and has now been noted in many countries. By 2030, 25% of American patients diagnosed with rectal cancer will be 49 years or younger. The large majority of EOCRC cases are not found in patients with germline cancer susceptibility mutations (eg, Lynch syndrome) or inflammatory bowel disease. Thus, environmental or lifestyle factors are suspected drivers. Obesity, sedentary lifestyle, diabetes mellitus, smoking, alcohol, or antibiotics affecting the gut microbiome have been proposed. However, these factors, which have been present since the 1950s, have not yet been conclusively linked to the abrupt increase in EOCRC. The sharp increase suggests the introduction of a new risk factor for young people. We hypothesized that the driver may be an off-target effect of a pharmaceutical agent (ie, one requiring regulatory approval before its use in the general population or an off-label use of a previously approved agent) in a genetically susceptible subgroup of young adults. If a pharmaceutical agent is an EOCRC driving factor, regulatory risk mitigation strategies could be used.
OBJECTIVE: We aimed to evaluate the possibility that pharmaceutical agents serve as risk factors for EOCRC.
METHODS: We conducted a case-control study. Data including demographics, comorbidities, and complete medication dispensing history were obtained from the electronic medical records database of Maccabi Healthcare Services, a state-mandated health provider covering 26% of the Israeli population. The participants included 941 patients with EOCRC (≤50 years of age) diagnosed during 2001-2019 who were density matched at a ratio of 1:10 with 9410 control patients. Patients with inflammatory bowel disease and those with a known inherited cancer susceptibility syndrome were excluded. An advanced machine learning algorithm based on gradient boosted decision trees coupled with Bayesian model optimization and repeated data sampling was used to sort through the very high-dimensional drug dispensing data to identify specific medication groups that were consistently linked with EOCRC while allowing for synergistic or antagonistic interactions between medications. Odds ratios for the identified medication classes were obtained from a conditional logistic regression model.
RESULTS: Out of more than 800 medication classes, we identified several classes that were consistently associated with EOCRC risk across independently trained models. Interactions between medication groups did not seem to substantially affect the risk. In our analysis, drug groups that were consistently positively associated with EOCRC included beta blockers and valerian (Valeriana officinalis). Antibiotics were not consistently associated with EOCRC risk.
CONCLUSIONS: Our analysis suggests that the development of EOCRC may be correlated with prior use of specific medications. Additional analyses should be used to validate the results. The mechanism of action inducing EOCRC by candidate pharmaceutical agents will then need to be determined.

BACKGROUND: A work accident constitutes a shock to health, likely to alter mental states and affect the use of psychotropic drugs. We focus on the use of benzodiazepines, which are a class of drugs commonly used to treat anxiety and insomnia. Prolonged use can lead to dependence. Our objective is to determine the extent to which work accidents lead to benzodiazepine use and overuse (i.e. exceedance of medical guidelines).
METHODS: We use a two-step selection model (the Heckman method) based on data from the French National Health Data System (Système National des Données de Santé, SNDS). Our study sample includes all general plan members who experienced a single work accident in 2016 (and not since 2007). This sample includes 350,000 individuals in the work accident group and more than 1.1 million people randomly drawn from the population without work accidents from 2007 to 2017 (the non-work accident group).
RESULTS: The occurrence of a work accident leads to an increase in benzodiazepine use and overuse the following year. The selection model shows a clear influence of the accident on the use probability (+ 39%), but a very slight impact on the risk of overuse among users (+ 1.7%), once considered the selection effect. The effect on overuse risk is higher for more severe accidents and among women.
CONCLUSIONS: The increase in the risk of benzodiazepine overuse is due to an increase in the likelihood of using benzodiazepines after a work accident that leads to overuse, rather than an increase in likelihood of overuse among people who use benzodiazepines. Results call for targeting the first-time prescription to limit the risk of overuse after a work accident.
