Acute pancreatitis induced by Tadalafil: a case report. Clin J Gastroenterol 2019; 13:459-464. [PMID: 31797202 DOI: 10.1007/s12328-019-01070-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 11/06/2019] [Indexed: 10/25/2022]
Abstract
Acute pancreatitis is commonly caused by gallstones or alcohol abuse. Also, this complication has rarely been associated with other etiologies like drugs in some reports. We report the case of a 43-year-old man with 10-days history of taking Tadalafil for erectile dysfunction. The patient was presented to the emergency room with manifestations of acute pancreatitis. This diagnosis was confirmed after clinical examination, laboratory tests, and radiologic evaluation. Other probable etiological factors were ruled out. A total score of seven using Naranjo Adverse Drug Reaction Probability Scale clarifies a probable diagnosis of drug-induced acute pancreatitis in this case. The reported case of acute pancreatitis was most likely induced with Tadalafil.

Contributions of a blended learning based on peer evaluation for teaching drug-drug interactions to undergraduate pharmacy students. BMC MEDICAL EDUCATION 2019; 19:426. [PMID: 31744484 PMCID: PMC6862800 DOI: 10.1186/s12909-019-1867-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/08/2019] [Accepted: 11/05/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Numerous studies have pointed out the need for better training of healthcare professionals in drug-drug interactions management in order to minimize adverse drugs reactions impacts on patients. The aim of this study was to evaluate the benefits of a blended learning strategy based on peer evaluation (PE) for teaching drug-drug interactions to undergraduate pharmacy students. METHODS Third-year pharmacy students (n = 72) from the University of Limoges were involved in a hybrid teaching using the Moodle platform (2.9 version). After the theoretical lectures, an online activity was proposed to students. Each student submitted a report addressing a clinical case for peer evaluation. Students evaluated the pedagogical approach using an online survey. Quantitative benefits were assessed from students randomly assigned into two groups: PE in pharmacodynamics items (PE-PD) or PE in pharmacokinetics items (PE-PK). During this activity, three marks were given: one from peers for their evaluation work and two from teachers for oral group presentation of the clinical cases and for the final written examination. Statistics were performed using two-tailed unpaired t-test and significance was set for p < 0.05. RESULTS Only a few students (n = 14, 20.6%) were aware of the peer evaluation principle and even less, only one student (n = 1, 1.5%), had already encountered it. Students considered that they benefited from this evaluation (n = 65, 95.6%); from their work being reviewed (n = 62, 91.2%) and that they participated in improving their classmates understanding (n = 59, 86.8%). Peers' allocated marks were similar in the two PE groups (PE-PD = 17.4 ± 1.4; PE-PK = 17.3 ± 1.4). Teachers' marks for oral presentation were significantly lower for pharmacodynamics than for pharmacokinetics items (PE-PD = 15.2 ± 1.2; PE-PK = 16.1 ± 2.1; p < 0.05). The final examination marks were equivalent in both groups (PE-PD = 11.0 ± 2.1; PE-PK = 11.2 ± 1.9). CONCLUSIONS Besides the fact that a major short-term quantitative improvement was not detected, our teaching approach was qualified as being a positive and stimulating learning tool by students.

[PMID: 31784043 DOI: 10.1016/j.imbio.2019.11.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Revised: 10/31/2019] [Accepted: 11/12/2019] [Indexed: 12/17/2022]
Abstract
The HLA-B*15:02 allele is associated with an increased risk of developing carbamazepine (CBZ)-induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Many studies, however, have demonstrated that a large majority of HLA-B*15:02 individuals are unlikely to develop the adverse drug reaction while on CBZ. This phenomenon suggests that other factors that modulate the allergic immune response, such as regulatory T cells (Tregs), might contribute to an uncontrolled immune response in SJS/TEN. Peripheral blood mononuclear cells (PBMCs) from 15 healthy HLA-B*15:02 carriers were isolated to investigate the role of Tregs in controlling the immune response towards CBZ. Recognition of CBZ was assessed using enzyme linked immunosorbent spot (ELISPOT) assay for IFN-γ, and the donor T-cell profiles were quantified by flow cytometry to differentiate CBZ responders from non-responders. As CD39 expression on Tregs promotes immune tolerance, we investigated the mechanisms of Treg suppression using inhibitors targeting the CD39/adenosinergic pathway. PBMCs from seven donors (responders) produced high levels of IFN-γ when re-exposed to CBZ, while eight donors (non-responders) did not. Flow cytometric analysis revealed that non-responders produced significantly higher frequencies of CD4+CD25+CD127loCD39+FoxP3+ Tregs compared to responders. CD39 inhibition using POM-1 inhibitor converted five of the eight non-responders into responders (P < 0.05). Higher frequencies of CD4+CD25+CD127loCD39+FoxP3+ Tregs was correlated with lower production of IFN-γ (P < 0.01). Our data suggest that CD4+CD25+CD127loCD39+FoxP3+ Tregs may play a role in promoting CBZ tolerance in HLA-B*15:02 carriers. The CD39/adenosinergic axis can be a potential target to alleviate the uncontrolled immune response during this adverse drug event.

Abstract
BACKGROUND Collagenase Clostridium histolyticum (CCH) is a recent treatment for Dupuytren disease, which is a fibroproliferative disorder that leads to progressive, persistent digital flexion contracture that interferes with basic daily activities. While CCH has changed the treatment of this hand disorder, numerous concerns have to be analyzed. AIMS Our purpose is to assess the current status of this medical treatment. METHODS Literary review based on a manual search on PubMed, Web of Science, and Google Academic. RESULTS Pharmacoeconomic analyses support the use of CCH, but long-term studies showing that it should be favored over conventional surgery or other treatments are lacking. Treatment decisions, therefore, must be guided by current data, which include a 5-year recurrence rate of 47%. Complications following CCH treatment are also a controversial topic, as rates of over 90% have been reported, although most of the complications are mild and self-limiting. A definition and classification of CCH-related complications is sorely needed. If we exclude adverse effects that could be considered inherent to the mechanisms of action of CCH, then the complication rate would be similar to rates reported for other techniques. Although CCH is becoming an increasingly popular treatment for Dupuytren disease, the potential applications of this modality, are much higher than currently believed, for more disorders characterized by excessive fibrosis. CONCLUSION Currently, the administration of this treatment is promising although long-term studies are necessary to see the real role that this drug can play in both Dupuytren's disease and other fibrotic disorders.

Abstract
Background While warfarin is the most commonly prescribed medication to prevent thromboembolic disorders, the risk of adverse drug reactions (ADR) poses a serious concern. This prospective study evaluated how primary care providers (PCP) and cardiologists at our Institution managed patients treated with warfarin with the goal of decreasing the number of warfarin ADRs. Methods A multidisciplinary anticoagulation task force was established at our Institution in 2014 to standardize warfarin monitoring and management. Between 2013 and 2017, we analyzed patients who were prescribed warfarin by their PCP or cardiologist upon hospital discharge and in the ambulatory setting to determine the international normalized ratio (INR) within 5, 10, and 30 days after discharge, time in therapeutic range (TTR), number of severe warfarin ADRs, and total and average cost reduction of all severe warfarin ADRs to determine whether there was an organizational cost savings following the implementation of standardized warfarin care. Results The warfarin ADR rate significantly decreased over the 5-year period, from 3.8 to 0.98% (p < 0.0001). The proportion of warfarin prescriptions out of all anticoagulants significantly decreased, from 72.2 to 42.1% (p < 0.001). The proportion of individuals who received an INR at 5, 10, and 30 days after hospital discharge compared to the total number of patients prescribed warfarin significantly increased (p < 0.001). The total cost of severe warfarin ADRs decreased by 57.6% between 2013 and 2017. Conclusions This study serves as a model to reduce the number of severe warfarin ADRs by the following tactics: (1) educating PCPs and cardiologists about evidence-based guidelines for warfarin management, (2) increasing the use of our Institution’s electronic warfarin module, and (3) enhancing patient compliance with obtaining INR.

Abstract
Objective: To derive findings from different studies done on drug related hospital admissions and comprehensively express the incidence and preventability of drug related hospital admissions; identify the common types of drug related problems that caused hospital admission, and identify factors associated with drug related hospital admission. Methods: Literatures that assessed hospitalization due to drug related problems were searched online using Pub Med and Google Scholar databases. The relevant reference lists of retrieved articles were also searched manually on Google. Prospective and retrospective studies conducted anywhere in the world on drug related hospitalization, published from January 2012 to January 2017 as an original article and written in English language were included. Result: The prevalence of drug related hospital admission varies from 1.3% to 41.3% with the average rate of 15.4%. Among hospitalized patients 2.7% were died due to drug-related problems (DRPs). Drugs that were frequently reported as causing drug related admission were antithrombotic drugs, antihypertensive drugs, analgesics, anti-diabetics, antipsychotics, and anti-neoplastic drugs. Poly pharmacy, old age and female sex were mentioned as determinants for drug related hospitalization by a number of studies. About one third of drug related hospital admissions were definitely preventable and more than 40% were also potentially preventable. Conclusion: Drug related problems contribute for more than 15% of hospital admissions. Higher risk of admission due to DRPs was observed in patients who were on poly pharmacy and those who were old. As most of drug related hospital admissions were preventable an emphasis should be given for preventive strategies to avoid complications and costs associated with admission.

Abstract
Sudden cardiac death (SCD) is relatively uncommon, yet it is a deadly consequence of some antipsychotic medications in patients with psychiatric disorders. The widespread concerns about the adverse cardiac effects associated with antipsychotics and their unpredictable nature have led to a restriction on the use of some antipsychotic medications. Recent progress has been made in the identification of important genetic factors that may contribute to the adverse complication of antipsychotic drugs, suggesting that high-risk individuals can be identified prior to initiating therapy. In addition, some high-tech smart wearable medical devices have recently been developed, allowing users to record and analyze the electrocardiogram (ECG) in couple with artificial intelligence (AI) technologies, and notifying of irregular heart rhythms or arrhythmias, a medical condition well documented in most SCD cases. In this literature review, we summarize recent advances in understanding the link between SCD and antipsychotic drug usage, as well as in utilizing wearable medical devices for monitoring of cardiac arrhythmias. New strategies for improving the care of patients receiving antipsychotic medications are proposed. As it is now possible to evaluate the risk of SCD in patients on antipsychotic medications, preventative measures and close monitoring may be used to detect the early signs of adverse cardiac events and SCD.

Abstract
Background: Intravenous immunoglobulin (IVIG) is a pooled human plasma protein that has
shown efficacy in treating a variety of disorders. IVIG is generally well
tolerated and has a good safety profile. There are various IVIG products
available on the market, which results in differences in efficacy and safety
profile. The aim of this study was to assess the safety profile of IVIG use
in pediatric patients and its association with other predicted factors. Methods: Retrospective chart review study of all pediatric patients who received IVIG
as an inpatient at Hamad General Hospital in Qatar during 2014. The
occurrence of adverse drug reactions (ADR) was tested for any association
with other predicted factors, such as patient age, IVIG dose, brand, and
adherence to infusion protocol. Results: A total of 345 IVIG prescriptions were received by pediatric patients during
the study period. Most common documented side effects were: fever (5.8%),
chills (2.6%), and headache (2%). Renal insufficiency was observed only in
six cases, with five of those in ‘Risk’ category according to RIFLE
criteria. A hypersensitivity reaction was documented in seven patients,
despite being premedicated with paracetamol and/or diphenhydramine and
following the infusion protocol. None of the predicted factors were found to
be significantly associated with ADR incidence except IVIG brand. Conclusions: IVIG generally has a good safety profile in pediatric patients, with low risk
of severe ADR. More studies are needed to evaluate the correlation between
ADR and IVIG formulation, taking into account other factors that may affect
results.

Abstract
OBJECTIVE We aimed to develop and validate a new instrument called Questionnaire for the assessment of the knowledge, management and reporting ADR in Paediatrics by Healthcare teams (QUESA-P). DESIGN This is a cross-sectional study. SETTINGS AND PARTICIPANTS Teams of healthcare professionals (HCP) that lead with pharmacological therapy in Paediatrician's sector (Paediatric-HCP) in seven public hospitals in Brazil. OUTCOME An assessment of the knowledge and current management of ADR in Paediatric-HCP. METHODS We developed and validated QUESA-P, using a standardised procedure which included item development and psychometric prevalidation using Cronbach's Alpha, item-total correlation and test-retest validity for internal consistency and reliability. External criterion was used as criterion validation (the instrument was applied to the focus group expert vs focus group team of Paediatric-HCP in hospitals). The focus group of experts who participated in psychometrics was asked to respond to the QUESA-P twice in order to assess test-retest reliability. The content validity of the initial questionnaire was assessed by the Delphi method and pilot test. Subsequently, we made minor revisions and finalized the QUESA-P RESULTS: Selection of domains and facets were based on literature review made in duplicate by authors. Content validity was done by trial of different examiners (panellists, n=16), conducting analysis through Delphi method (three rounds). The QUESA-P was constructed with three domains. The intraclass correlations (0.80) and the Cronbach's alpha coefficient (0.82), indicated adequate test-retest reliability and internal consistency for each domain. The application of the QUESA to 61 Paediatric-HCP in hospital resulted in lower mean score of 42.1 ± 3.4 in all domains when compared with expert teams (n= 46) 48.2 ± 3.7 (p <0.001) indicating that the instrument is valid to discriminate QUESA experts and Paediatric-HCP. CONCLUSION The selected domains can be used to check weaknesses in the identification, management and reporting of suspected ADR by Paediatric-HCP in Brazil.

Abstract
INTRODUCTION Mortality rates from various cancer types are higher in patients with hyperglycaemia-associated pathologies. Among antineoplastics for treating pancreatic carcinoma, doxorubicin was found to be top of the list for inducing hyperglycaemia-related adverse drug reactions. METHODS Individual case safety reports of doxorubicin-induced hyperglycaemia-related adverse drug reactions (HG-ADRs) submitted during the period 2000-2017 were extracted from VigiBase®. Factors influencing outcome seriousness in these cases were analyzed using bivariate correlation and logistical regression. Age was stratified into five groups. RESULTS Among the 558 cases with high blood glucose included in this study, with an average patient age of 55.9 ± 14.3 years, 71.1% had serious outcomes and 10.9% died. Three factors-died, age, and gender-were all found to be significantly correlated with outcome seriousness (P < 0.01), while five factors-year reported, ADR duration, latency, treatment duration, and dosage-showed no correlation with outcome seriousness (P > 0.05). Identical conclusions were reached upon analyzing only the cases that did not involve corticosteroid use. CONCLUSION Age and gender are risk factors for doxorubicin-induced serious HG-ADRs; males and older patients are more likely to suffer a serious outcome following such a reaction.

Abstract
INTRODUCTION Adverse drug events/reactions (ADE/ADRs) cost more than $30 billion annually and are among the leading causes of death in the USA. Little is known about patients treated at the bedside for ADE/ADR by medical toxicologists. METHODS We conducted a retrospective study of ADE/ADR cases reported to the Toxicology Investigators Consortium (ToxIC) registry between January 1, 2010, and December 31, 2016. Clinical and demographic data were collected including age, sex, circumstances surrounding exposure, suspected offending substance, clinical manifestations, treatment, disposition, and outcome. RESULTS Among 51,440 ToxIC cases during this time period, 673 ADE/ADR cases were reported (337 females). By age, ADE/ADRs were seen most commonly among adults age 19-65 years (442/673, 65.7% of ADE/ADR) and older adults age 65-89 years (134/673, 19.9% of ADE/ADR). 222/673 (33%) of consults for ADE/ADR were seen in the emergency department (ED); 181/673 (26.9%) were seen in the hospital ward; and 160/673 (23.8%) were seen in the intensive care unit (ICU). The most commonly reported sign for ADE/ADR was tachycardia: 51/673 (7.6%), followed by bradycardia: 49/673 (7.3%). Most commonly reported agents associated with ADE/ADR were as follows: 97/673 (14.4%) due to cardiovascular medications; 76/673 (11.3%) due to antipsychotic medications; and 61/673 (9.1%) due to antidepressants. 429/673 (63.7%) of ADE/ADR were reported as due to a single agent, and 212/673 (31.5%) were reported as due to multiple agents. CONCLUSIONS 4.2% of cases managed at the bedside by a consulting toxicologist and reported to the ToxIC registry between 2010 and 2016 had ADE/ADR as the reason for consultation. Agents most commonly involved in ADE/ADRs included cardiovascular medications, antipsychotic medications, and antidepressants.

Abstract
Immunotherapy is a "hot" area in schizophrenia research. Monoclonal antibodies (mAbs) target specific immune molecules, and therefore offer an unparalleled opportunity to directly test the hypothesis that immune dysfunction plays a causal role in psychopathology in schizophrenia. Cytokine-based immunotherapy for other disorders has been associated with a range of neuropsychiatric adverse effects, including psychosis. The purpose of the present study was to investigate the prevalence of spontaneously-reported adverse drug reactions of psychotic symptoms for mAbs, and to calculate odds of psychosis for individual mAbs, compared to bevacizumab, which does not directly target the immune system. We searched the publicly available VigiBase, a World Health Organization global individual case safety report database from inception through February 2019 for which a mAb was the suspected agent of an adverse drug reaction (ADR). We investigated 43 different mAbs, comprising 1,298,185 case reports and 2025 psychosis ADRs. For individual mAbs, the prevalence of psychosis ADRs ranged from 0.1 to 0.4%. Seven mAbs were associated with a significantly increased odds of psychosis (OR = 1.42-2.22), including two agents that target CD25. Eight mAbs were associated with a significantly decreased odds of psychosis (OR = 0.28-0.75), including 4 anti-TNF-α agents. Our results suggest that psychosis is a relatively rare adverse effect of mAb treatment, but risks vary by specific agents. Findings indicate that modulating the immune system may sometimes lead to the development of psychosis. Ongoing clinical trials of adjunctive mAb immunotherapy in schizophrenia will provide valuable insights into the role of the immune system in psychosis.

Abstract
Reports of metamizole-induced neutropenia have increased in Switzerland and Germany over the last decades, most likely reflecting increased use of metamizole. To date, there are no effective strategies to identify patients at increased risk of metamizole-induced neutropenia. In this observational, multi-center comparative study, characteristics of patients with metamizole-associated neutropenia were compared with patients treated with metamizole without developing adverse hematological reactions. Patients with metamizole-induced neutropenia treated at the University Hospitals Basel and Bern between 2005 and 2017 were included. Tolerant comparison patients with continuous metamizole treatment (≥500 mg/day for at least 28 days) were recruited from GP offices and community pharmacies. Forty-eight patients with metamizole-induced neutropenia, consisting of 23 and 25 cases with inpatient-acquired and outpatient-acquired neutropenia, respectively, were compared to 39 metamizole tolerant comparison patients. Median latency until first diagnosis of neutropenia was 6 days (1-61 days) in inpatient cases and 19 days (2-204 days) in outpatient cases. There was no association between non-myelotoxic and non-immunosuppressive co-medication (p = .6627), history of drug allergy (p = .1304), and preexisting auto-immune diseases (p = .2313) and the development of metamizole-induced neutropenia. Our results suggest that autoimmune diseases, history of drug allergy, and concomitant treatment with non-myelotoxic and non-immunosuppressive drugs are likely not individual risk factors for metamizole-associated neutropenia.

Abstract
Dipeptidyl peptidase-4 inhibitors (DPP-4i) are one of the mainstay drugs in the management of type 2 diabetes mellitus. It has been well-documented that these class of drugs cause allergic reactions. Bullous pemphigoid (BP) is a blistering skin condition commonly associated with many drugs. Here, we report a case of probable DPP-4i-induced BP in an elderly man, which resolved on discontinuation of the drug. Although this adverse drug reaction has been documented in Western world and Japanese ethnicity, this seems to be the first case report of such occurrence in Indian ethnicity.

Abstract
Usage of cancer chemotherapeutics drugs can be associated with adverse drug reactions. When IgE-mediated drug reactions are formed following administration of a chemotherapeutics drug that is a drug of choice, drug desensitization protocols can be helpful. HSR can be allergic or nonallergic, but the clinical manifestations are similar. RDD is effective when used appropriately, however it is often over utilized instead of performing a drug challenge. RDD is both an acceptable approach and a high-risk treatment modality in patients, in whom the offending agent is the first choice in chemotherapy. The safety of this modality has been acceptable in large studies. The side effects are often less frequent and less severe by repeating the protocol. We present 4 cases of successful desensitization in cancer patients, who have developed IgE- mediated reactions to their major chemotherapy drug.

Abstract
Background: Adverse drug reactions (ADRs) associated with antiretroviral therapy (ART) can rapidly reverse the gains of ART resulting in poor health outcomes. We need an improved under-standing of specific ART-related ADRs that influence virologic outcomes. Objective: To investigate the frequency of clinical ADRs and assess their effect on virologic failure in patients on ART. Method: We described the prevalence of major clinical ADRs, and the association between specific ADRs and virologic failure in a clinic cohort of HIV-1 infected Nigerians aged ≥18 years, on first-line ART between June 2004 and February 2012. Multivariable logistic regression was run to identify predictors of virologic failure at 24 and 72 weeks of ART. Results: Data of 12,115 patients with a median age of 34 (interquartile range: 29-41) years, and pre-dominantly females (67%) were evaluated. Overall, 957 (7.9%) patients experienced at least one ADR during a median follow-up period of 4 years (interquartile range: 1-7). The three most prevalent ADRs were lipodystrophy (2.6%), anemia (1.9%), and skin rash (0.7%). Virologic failure rate was 36% and 34% at 24 and 72 weeks of ART, respectively. Anemia independently predicted the odds of virologic failure at 72 weeks of ART (adjusted odds ratio, 1.74; 95% CI: 1.2-2.51); adjusted for sex, age, pre-treatment CD4+ cell count, antiretroviral regimen, and medication refill adherence. Conclusion: Antiretroviral therapy-associated anemia increases the likelihood of late virologic failure. We recommend routine monitoring of hemoglobin levels and prompt management of anemia in all pa-tients on ART as a strategy to improve virologic success rates.

Abstract
Background Personalized feedback received for spontaneous adverse drug reaction (ADR) reports serves as motivation for future reporting and the effectiveness of the feedback is dependent on the medium used in delivering the information. Objective Explore expectation for feedback from patients on ADR reports submitted to the National Pharmacovigilance Centre (NPvC) in Ghana and the preferred medium for receiving the feedback information. Methods Cross-sectional study using structured questionnaire administered through face-to-face interview from August to September 2016 to patients selected by convenience sampling. Pearson chi-square (§2) or Fisher's exact test was used to determine associations between background variables such as age, gender and level of education. Results The response rate was 86.7% (n=442). Of the participants interviewed, 96.5% expected to receive feedback for ADR reports submitted. Age and level of education were the two variables significantly associated with patients' expectation for feedback. The preferred medium for receiving feedback in decreasing order of preference were, telephone call (60.4%), mobile phone short messaging services (23.0%), email (8.3%), face-to-face meeting (3.4%), personalized letter (3.4%) and publication in a newsletter (1.4%). Conclusion Patients' expectation for receiving feedback for ADR reports submitted to the NPvC is in line with modern trends in communication. NPvC should explore these alternatives for providing feedback to patients. This study is limited to what patients' expectations and preferences were for receiving feedback on ADR reports submitted, additional study to further explore the type of information patients expect to be contained in the feedback will be useful to National Pharmacovigilance Centres.

Abstract
Background Pharmaceutical opioid analgesic use continues to rise and is associated with potentially preventable harm including hospitalisation for adverse drug reactions (ADRs). Spatial detection of opioid-related ADRs can inform future intervention strategies. We aimed to investigate the geographical disparity in hospitalised ADRs related to opioid analgesic use, and to evaluate the difference in patient characteristics between areas inside and outside the geographic clusters. Methods We used the all-inclusive Admitted Patient Dataset for an Australian state (New South Wales, NSW) to identify patients admitted for opioid-related ADRs over a 10-year period (July 2004 to June 2014). A space-time analysis was conducted using Kulldroff’s scan statistics to identify statistically significant spatial clusters over time. Relative risk (RR) was computed with p-value based on Monte Carlo Simulation. Chi-square test was used to compare proportional difference in patient clustering. Results During the study period, we identified four statistically significant geographic clusters (RRs: 1.63–2.17) during 2004–08; and seven clusters (RRs: 1.23–1.69) during the period 2009–14. While identified high-risk clusters primarily covered areas with easier access to health services, those associated with socioeconomically disadvantaged areas and individuals with mental health disorders experienced more unmet healthcare needs for opioid analgesic safety than those from the rest of the State. Older people (≥65 years and over) accounted for 62.7% of the total study population and were more susceptible to opioid-related ADRs than younger people,. In the first five-year period the clusters included a greater proportion of people with cancer in contrast to the second five-year period in which there was a lesser proportion of people with cancer. Conclusions These results suggest that there is significant spatial-temporal variation in opioid-related ADRs and future interventions should target vulnerable populations and high-risk geographical areas to improve safer use of pharmaceutical opioid analgesics.

Abstract
BACKGROUND Malarone® is a drug used for the treatment of malaria in humans. This drug is also particularly effective in the treatment of canine Babesia gibsoni infections. Malarone® is rarely used in dogs, and its adverse effects have not been widely reported. Its mechanism of action is related to the inhibition of cytochrome b and electron transport in the cell. This is the first known report of the development of acute pancreatitis and alopecia in a dog following the administration of Malarone®. CASE PRESENTATION A 3-year-old, intact, female Maltese was referred to our clinic with intermittent vomiting and sudden, generalized alopecia. Two months previously, the dog had been prescribed Malarone® for the treatment of a suspected B. gibsoni infection. The dog was evaluated using hematology, radiography, ultrasonography, a PCR for Babesia detection, and a canine pancreatic lipase immunoreactivity (cPLI) assay. The result of the PCR test was negative, whereas the cPLI assay yielded a positive result. Dermatologic examination revealed bacterial infection with hair cycle arrest. CONCLUSIONS Based on these findings, drug-induced acute pancreatitis and alopecia with superficial pyoderma were diagnosed. Malarone® may induce severe adverse reactions in dogs. Therefore, careful monitoring for adverse effects is required when using Malarone® in dogs.

Abstract
OBJECTIVES To identify the clinical determinants of fever in clozapine users and their impact on management of clozapine treatment. METHODS Articles published in English or French identified with a MEDLINE, Web of Sciences, Cochrane Library and PsycINFO search, from inception through February 2019, using the term "clozapine" in combination with "fever" OR "hyperthermia" OR "body temperature" OR "pyrexia" OR "febrile" OR "heat" OR "thermoregulation". Information extracted for each medical condition were frequency, time to onset after initiation of clozapine treatment, characteristics of fever, associated symptoms, laboratory tests used for diagnosis, course, lethality, discontinuation of clozapine. Data were synthesized narratively. RESULTS Our search yielded 394 unique hits published from 1993 to 2018. We included 73 articles in the review: two meta-analyses, 14 reviews, six epidemiological studies, 11 clinical studies and 40 case reports. During clozapine initiation, fever is most frequently benign and transient but should be closely monitored as it may be the first stage of potentially life-threatening adverse drug reactions (ADR) (agranulocytosis, neuroleptic malignant syndrome myocarditis, hepatitis, pancreatitis, nephritis, colitis, etc.). Other ADR associated with fever are independent of duration of exposure to clozapine (heat stroke, pneumonia, pulmonary embolism, necrotizing colitis). If fever is due to intercurrent infection, therapeutic drug monitoring is recommended to adjust clozapine daily dosage. CONCLUSION Benign causes of fever are much more frequent than life-threatening ADR during clozapine treatment. Discontinuation should not be considered as automatic in the event of fever, especially during the early phase of clozapine initiation.

Abstract
There are only few case reports available on NF resulting from molecular targeted therapy. This is the first case report of sorafenib-associated NF. Clinicians should be aware of this possible adverse effect of molecular targeted therapy.
We present here a case of extensive necrotizing fasciitis during sorafenib treatment in a patient with HBV-related hepatocellular carcinoma. Despite emergent extensive surgical debridement, the patient's clinical status progressive worsened until interruption of sorafenib therapy. The patient was successfully treated with temporal interruption of sorafenib therapy. To our knowledge, this is the first case report of sorafenib-associated necrotizing fasciitis. Given the life-threatening nature of the infection and the necessity for urgent intervention, clinicians should be aware of this possible adverse effect of tyrosine kinase inhibitors.

Abstract
Daclizumab, a monoclonal antibody directed against CD25, a subunit of the high-affinity IL-2 receptor, was licensed as a disease modifying therapy (DMT) for relapsing remitting multiple sclerosis in 2017. Interference with IL-2 signalling is hypothesised to modulate T cell function. For example it results in a preferential shift of innate lymphoid cell (ILC) into CD56bright natural killer cells and a decrease in regulatory T Cells. We present three patients who developed urticarial papulovesicular rashes at a median of 3 months after discontinuation of Daclizumab. We propose an unexpected T cell mediated immune reaction as the cause.

Abstract
Misuse of antimicrobials has become one of the grave concerns of public health. In last two decades, this has been largely contributing in the emergence of antimicrobial resistance (AMR) among all the pathogens. A 2013 report of Centres for Disease Control and Prevention, USA figured that at least 2 million people get an antibiotic-resistant infection every year and as many as 23,000 people lost their life. A multi-country survey in Southeast Asia region conducted by World Health Organization (WHO) in 2015, identified several gaps in knowledge and awareness about the optimal use of antimicrobials and AMR. Following this, the Ministry of Health and Family Welfare (MoHFW), Government of India, developed National Action Plan in the year 2017 to combat AMR. Pharmacovigilance Programme of India (PvPI) being a flagship programme of MoHFW holds the responsibility of ensuring safety of medicines used by India population and has recently identified AMR as one of the strategic priorities. This article intends to provide insights of the recent attempts and deliberate efforts made by PvPI in the containment of AMR in India and it also intends to sensitize healthcare fraternity on restricting AMR in public interest.
