Objective: To review the literature on drug-induced restless legs syndrome (DI-RLS). Data Sources: The review included a search for English-language literature from 1966 to December 2017 in the MEDLINE, PubMed, and Ovid databases using the following search terms: restless legs syndrome (RLS), periodic limb movement, adverse effects, and drug-induced. In addition, background articles on the pathophysiology, etiology, and epidemiology of RLS were retrieved. Bibliographies of relevant articles were reviewed for additional citations. Study Selection and Data Extraction: All case reports, case series, and review articles of DI-RLS were identified and analyzed. There were only a small number of controlled clinical trials, and most data were from case reports and case series. Results: Several drugs and drug classes have been implicated in DI-RLS, with antidepressants, antipsychotics, and antiepileptics having the most evidence. In addition, RLS may be linked with a number of disorders or underlying predisposing factors as well. Conclusions: The prevalence of RLS is variable and ranges from 3% to 19% in the general population. There are many predisposing factors to RLS, but an emerging body of evidence suggests that there is an association between numerous drugs and RLS.

Objectives: The purpose of this article is to review the current literature on drug-induced thrombocytosis with the goal of critically assessing causality and providing a comprehensive review of the topic. Thrombopoietic growth factors, such as thrombopoietin-receptor agonists (romiplostim and eltrombopag) and erythropoietin are not included in our review. Data Sources: The literature search included published articles limited to the English language and humans in MEDLINE, EMBASE, and Web of Science databases. MEDLINE/PubMed (1966 to September 2018) was searched using the MeSH terms thrombocytosis/chemically-induced and thrombocytosis/etiology. EMBASE (1980 to September 2018) was searched using the EMTAGS thrombocytosis/side effect. Web of Science (1970 to September 2018) was searched using the search term thrombocytosis. References of all relevant articles were reviewed for additional citations and information. Study Selection and Data Extraction: Review articles, clinical trials, background data, case series, and case reports of drug-induced thrombocytosis were collected, and case reports were assessed for causality using a modified Naranjo nomogram. Data Synthesis: Drug-induced thrombocytosis, a form of reactive thrombocytosis cannot be easily differentiated from more common etiologies of reactive thrombocytosis. In all, 43 case reports of drug-induced thrombocytosis from a wide variety of drugs and drug classes were reviewed using a modified Naranjo probability scale that included criteria specific for thrombocytosis. Conclusions: Drug-induced thrombocytosis is a relatively rare adverse drug reaction. The strongest evidence of causality supports low-molecular-weight heparins and neonatal drug withdrawal. Weaker evidence exists for all-trans retinoic acid, antibiotics, clozapine, epinephrine, gemcitabine, and vinca alkaloids.

Objective: To examine the use of prostaglandin F2 alpha in treating cyclophosphamide-induced hemorrhagic cystitis. Data Sources: An English language literature search using MEDLINE 1982–1993 and bibliographic reviews of related textbooks and review articles. Study Selection: Articles containing pertinent information regarding the therapeutic use and effects of prostaglandin F2 alpha as a treatment for cyclophosphamide-induced hemorrhagic cystitis in humans. Data Extraction: Resources were evaluated and information was extracted independently. Data Synthesis: A review of human cases suggests that intravesical administration of prostaglandin F2 alpha may be an effective bedside therapy for cyclophosphamide-induced hemorrhagic cystitis. Adverse reactions are limited primarily to local effects. The optimal dosage regimen of intravesical prostaglandin F2 alpha is not clearly established. Conclusions: Patients with intractable vesical hemorrhage secondary to cyclophosphamide administration may benefit from bedside intravesical instillation of prostaglandin F2 alpha. Information in the literature regarding prostaglandin bladder irrigation is scarce, and confined to case reports. Clinical studies are needed to endorse and/or refute the efficacy of intravesical instillation of prostaglandin F2 alpha as a treatment modality for hemorrhagic cystitis.

Objective To describe a case of isoniazid-associated psychosis and review the incidence of this adverse effect. Data Sources Information about the patient was obtained from the medical chart. A MEDLINE search of the English-language literature published from 1950 to 1992 was conducted and Index Medicus was manually searched for current information. Study Selection All case reports describing isoniazid-associated psychosis were reviewed. Data Extraction Studies were evaluated for the use of isoniazid, symptoms of psychosis, onset of symptoms, and dosage of isoniazid. Data Synthesis The case report is compared with others reported in the literature. The incidence of isoniazid-associated psychosis is rare. Conclusions The mechanism of isoniazid-associated psychosis is uncertain. It appears that isoniazid was associated with the psychosis evident in our patient and in the cases reviewed.

Life Threatening

Objectives: Yew plant materials contain highly toxic taxine alkaloids. Serious ingestions can result in life-threatening toxicity. The purpose of this article is to summarize the literature on the treatment of acute yew poisoning. Data Sources: PubMed (January 1946 to November 2017) was searched using the search terms “taxus/po”. EMBASE (1980 to November 2017) was searched using the search terms “taxus/to” and “yew.mp.” Web of Science (1945 to November 2017) was searched using the text words taxus, taxine, and yew. Study Selection and Data Extraction: Available English language articles involving case reports, epidemiology, treatment, and outcomes were included. Data Synthesis: Although not uncommon, unintentional yew poisoning rarely results in significant morbidity or mortality. A total of 26 case reports of yew poisoning were evaluated along with 4 case series articles (totaling 22 additional cases). Only 4 of the 48 total cases (8%) were accidental poisonings, the rest being deliberate ingestions. In 20 patients (42%), it resulted in fatalities. Severe, acute yew poisoning results in symptomatology largely resistant to pharmacotherapy intervention. Conclusions: Most nonintentional ingestions of yew plant constituents are asymptomatic and require little intervention. Severe poisoning can result in life-threatening cardiac toxicity and require aggressive supportive care. Therapeutic interventions, such as sodium bicarbonate, digoxin immune fab, and hemodialysis that have been utilized in case studies and case series in the literature have little proven benefit. Extracorporeal life support should be considered in severe yew poisoning.

Objective To review the treatment modalities available for paraphimosis, with special emphasis on those applicable to the emergency department. Data source Relevant medical literature was searched through MEDLINE, EMBASE, CINAHL, and Cochrane Database. Manual search was performed in books on Urology, General Surgery and Emergency Medicine available in the Hospital Library. Further information was obtained through the Internet at < www.infoseek.com >. References cited in articles were also retrieved. Study selection Key words for the literature, Internet and textbook search were ‘paraphimosis’ and ‘treatment’. All available years of study were reviewed. Data extraction Relevant full text articles were obtained through the hospital library network. Original articles, review papers, medical practice, case reports, and relevant book chapters were reviewed. Data synthesis There were no prospective, randomised, controlled studies available. The majority were case series and expert experience or opinions only. Currently, a multitude of non-invasive and invasive treatment options are available, including manual reduction, help of non-crushing tissue forceps, puncture technique and dorsal slit. Conclusion All treatment methods are within the capability of the emergency physician. Hospitalization should rarely be required, unless there are serious complications.

Objective: To review the current literature on drug-induced yawning. Data Sources: Literature was accessed through MEDLINE/PubMed (1996-July 2011), International Pharmaceutical Abstracts (1997-July 2011), and EMBASE, using the search terms yawning, drug-induced yawning, and adverse drug reactions. Study Selection and Data Extraction: Relevant clinical trials and case reports were selected and included to present background information. Bibliographies of all relevant articles were reviewed for additional citations. Data Synthesis: Yawning is a common stereotype behavior with unknown physiologic function that occurs in most vertebrates and humans as early as 15 weeks of intrauterine life. Yawning Is under the control of several neurotransmitters and neuropeptides, Including dopamine, serotonin, oxytocin, and acetylcholine. Among drugs, antidepressants, opioids, dopaminergic agents, benzodiazepines, and induction agents are the main pharmacologic classes associated with yawning. Conclusions: Yawning is rarely a serious adverse reaction and is not frequently listed in the drug summary. Most available data are based on case reports, small studies, and older literature. Clinicians should be aware of the agents commonly triggering this behavior.

OBJECTIVE: The objective of this review is to discuss the pathophysiology and potential etiologies of rhabdomyolysis in psychiatric patients, with an emphasis on psychotropic drug-induced rhabdomyolysis. DATA SOURCES: References were obtained through an on-line search of MEDLINE, using English-language and human literature only. STUDY SELECTION: Because the topic is a potential drug-induced adverse effect, no controlled studies are available. Most of the literature are case reports and series of case reports. DATA EXTRACTION: The quality of case reports was assessed using the Food and Drug Administration guidelines for assessing the causality of a potential adverse drug reaction. DATA SYNTHESIS: The results of this review are based on qualitative data and indicate that rhabdomyolysis in psychiatric patients can be from multiple etiologies, including agitation, dehydration, and intramuscular injections, as well as an adverse effect of psychotropic medications. Although the deficiencies of this type of data are recognized, it is the only type of data often available to assess the etiology and causality of an uncommon adverse event. CONCLUSIONS: Rhabdomyolysis in psychiatric patients can be caused by many factors, both drug- and non—drug-related. Rhabdomyolysis is more likely to occur when patients are faced with a combination of risk factors. When combinations of factors are present (e.g., aggression and restraints, intramuscular injections, and extrapyramidal effects), or when muscle trauma from an individual factor is sufficiently traumatic, muscle necrosis may occur to the point that rhabdomyolysis ensues.

Tolerance Study

Objective: To review rifabutin-associated uveitis and discuss the mechanism and potential role of drug interactions with clarithromycin and fluconazole in contributing to this adverse event. Data Sources: A MEDLINE search (1991 through September 1994) of English-language literature using the main MeSH headings “rifabutin” and “uveitis” and the subheadings “adverse effects” and “chemically induced.” Relevant articles also were selected from references of identified articles. Abstracts from recent medical conferences of infectious diseases, pharmacology, and HIV were screened for additional data. Study Selection and Data Extraction: All articles and abstracts reporting uveitis potentially related to rifabutin were considered for inclusion. Fifty-four cases were identified. Pertinent information from the case reports, as judged by the authors, was selected and synthesized for discussion. Data Synthesis: Rifabutin is being prescribed increasingly for the treatment and prophylaxis of Mycobacterium avium complex (MAC) infection in the HIV-infected population. Uveitis was initially thought to be a rare, dose-limited complication of rifabutin therapy. In an early dose-ranging tolerance study, uveitis was associated with daily doses of 1200 mg or more. Because this toxicity appeared to be dose-related, lower dosages (300–600 mg/d) of rifabutin were selected for study in subsequent clinical trials. More recent reports noting the association of uveitis with these lower dosages of rifabutin have raised concerns about the prevalence of this adverse event. In the 54 identified cases, patients presented with symptoms of unilateral or bilateral uveitis from 2 weeks to more than 7 months following initiation of rifabutin therapy. In all reported cases, patients were receiving concurrent therapy with clarithromycin and/or fluconazole, both of which have inhibitory effects on rifabutin metabolism. In most cases, uveitis resolved within 1–2 months following discontinuation of rifabutin with or without administration of topical corticosteroids. Conclusions: Rifabutin is prescribed frequently for the prophylaxis and treatment of MAC infection, especially in patients with HIV. Uveitis is a rare, dose-related toxicity of this therapy. The risk of rifabutin-associated uveitis may be increased in patients receiving concurrent therapy with clarithromycin or fluconazole because of drug interactions. Patients receiving therapy with combinations of any of these agents should be warned about signs and symptoms of uveitis and be monitored closely for the development of rifabutin toxicity. If uveitis develops, rifabutin therapy should be discontinued promptly.

Objective: To provide a better understanding of the efficacy and possible adverse effects of topical aminophylline in causing regional fat loss. Data Source: Pertinent English-language literature (1958–1995). Study Selection: Representative articles documenting mechanisms of action and types of drug-induced reactions, as well as treatment options. Data Extraction: Data were extracted only from articles that documented relevant and substantive information backed by clinical studies. Data Synthesis: Topical aminophylline 2% thigh cream has been introduced as a method of treating cellulite, or dimpled thighs and buttocks. The proposed method of action is by increasing local concentration, thereby stimulating lipolysis. Data from two small clinical trials showed that the cream reduced thigh girth and had no known adverse effects. However, adverse dermatologic effects caused by aminophylline have been reported in the past. Conclusions: Topical aminophylline cream appears to be a reasonable option for regional reduction of thigh girth for some people and has not shown any adverse effects. Nevertheless, larger, long-term studies need to be done.

In Pregnancy

Objective: To evaluate the teratogenic potential of statins in women of child-bearing age. Data Sources: A PubMed search (1980-September 2012) was performed using the search terms statin and pregnancy, then repealed using statin and teratogenicity. Results were limited to articles published in English reporting on use of statins in humans. Study Selection and Data Extraction: All articles presenting data on pregnancy outcomes after statin use during any trimester of pregnancy were included. Three case reports, 2 case series, 2 systematic reviews, 2 registry-based studies, and 1 prospective observational cohort study were reviewed. Data Synthesis: Since initial premarketing studies of lovastatin in animals, terato-genesis has been assumed to be a classwide function of statins' mechanism of action. Data from human exposure during pregnancy have been gathered and analyzed in a variety of study formats to formulate useable conclusions on statins' actual teratogenic risk and pattern of associated birth defects. Although the current trend is that actual risk is lower than once thought, the available literature is limited by potential reporting bias, contains overlap in the data, and frequently lacks numbers of total exposures to statins during pregnancy with reported malformations. Additionally, no human studies included data on the 2 newest statins (rosuvastatin, pitavastatin); the more lipophilic statins (lovastatin, simvastatin) have the most experience and thus have more evidence related to teratogenic potential. Conclusions: Human teratogenic risk has not been proven nor has it been ruled out by the available data on statin use in pregnancy. Possible differences in risk between individual statins require further evaluation. Additional data, including prospective observational cohorts with inadvertent maternal exposure to statins during early weeks of gestation, should further help to clarify appropriate recommendations for statin use in this population.
