A 24-year-old woman with atopic dermatitis and persistent fever (axillary temperature of 37-38 °C for 6 months) received combination ophthalmic drops containing tropicamide and phenylephrine (Mydrin® -P), which exacerbated her fever within 15 min after instillation. Her axillary fever reached 40.1 °C but resolved the following day. No new dermatological symptoms developed. Although the patient's fever may have been caused by either tropicamide or phenylephrine, neither of which have been reported to induce fever in topical formulations, atopic dermatitis and tropicamide's inhibitory effect on perspiration under hot and humid conditions may have been the more probable cause...

Peripheral antidopaminergic medication is frequently prescribed to treat nausea. However, domperidone is ill-famed for its severe cardiac adverse effects. Metoclopramide has been suggested as a relatively safe alternative because it has long been considered to have less significant cardiovascular adverse effects. We present an older patient who developed severe bradycardia and hypotension shortly after receiving intravenous metoclopramide. Cardiac adverse effects of metoclopramide in elderly are not frequently described in the literature, especially not in patients without a major history of cardiac disease...

Fixed drug eruption (FDE) was caused by fixed-dose combination (FDC) of antituberculosis drugs in the form of tablet Forecox® (rifampicin [rifampin] 225 mg + isoniazid 150 mg + pyrazinamide 750 mg + ethambutol 400 mg) in a 40-year-old male patient with a history of drug allergy. The patient developed FDE after taking the third dose of tablet Forecox® for pulmonary tuberculosis. Tablet Forecox® was withdrawn and the patient recovered from the reaction after 15 days of treatment for FDE. As per World Health Organization-Uppsala Monitoring Centre (WHO-UMC) and Naranjo causality assessment criteria, the association between the reaction and tablet Forecox® was possible and probable, respectively...

Gynecomastia is a common finding in males, with an incidence that varies widely globally. In 10-25% of cases, it is caused by drugs. Its pathophysiologic mechanism includes exposure to exogenous estrogens and medications that cause hypogonadism, antiandrogenic effects and hyperprolactinemia. Gynecomastia is associated with exposure to antiretroviral therapy (ART), particularly efavirenz. Sometimes surgery may be required as treatment. We report a case of a 46-year-old man receiving ART presenting with a marked bilateral breast enlargement who underwent bilateral mastectomy as the only successful treatment in a low-income setting...

A 22-year-old man was admitted for an elective right-shoulder open subacromial decompression and distal clavicle excision. He received a single intravenous dose of fentanyl 50 μg for anesthesia. His procedure was completed without intra-operative complications; however, he developed post-operative respiratory depression in the setting of narcotic administration. He was given naloxone 0.2 mg intravenously once to reverse this effect, which subsequently led to acute hypoxic respiratory failure secondary to pulmonary edema shortly after administration of naloxone...

Fluoroquinolones are usually well tolerated with a minimum of serious adverse effects; renal toxicity is uncommon. Apart from the renal side effects of ciprofloxacin, we aimed to highlight the renal impact of a ciprofloxacin overdose, and thus conducted a prospective study in the Department of Nephrology at La Rabta Hospital between 2010 and 2015. The cohort database was continually updated until the inclusion of five patients who were subjected to an overdose and who were initially admitted to the medical intensive care unit and then transferred to our department for acute renal failure (ARF) due to ciprofloxacin ingestion requiring urgent hemodialysis...

A 55-year-old male was admitted to the hospital with pneumonia. During an intubation procedure, the patient received an application of endobronchial lidocaine (4% gel). Within 2 h of intubation, the patient developed worsening hypoxia, and investigation of arterial blood gasses revealed a pH of 7.21, carbon dioxide partial pressure (PaCO2 ) of 3.3 kPa, oxygen partial pressure (PaO2 ) of 55.1 kPa, and measured oxygen saturation of 49%. Co-oximetry of this sample returned a methemoglobin level of 53%. Intravenous methylthioninium chloride (1% solution at 1 mg/kg) was delivered, and subsequent arterial blood gasses, at 30 min and 1 h post administration, showed methemoglobin levels of 12 and 9%, respectively, with return of oxygen saturation to > 90%...

A 66-year-old male patient with a 10-year course of Parkinson's disease (PD) was admitted for hallucination lasting a half a month. After treatment with levodopa/carbidopa, selegiline, and piribedil, the patient's motor symptoms were improved while no significant effects were observed on psychotic symptoms. A clinical pharmacist analyzed the pharmacologic and pharmacokinetic characteristics of selegiline and piribedil, summarized the scheme of PD with psychotic symptoms in the literature, and discovered that selegiline might potentiate psychotic side effects of piribedil, while the use of levodopa/carbidopa cannot be ruled out either...

Medication errors remain among the major problems seen in hospitals. Such errors can relate to the prescription, dispensation, or administration of drugs. Human factors account for most of these mistakes, but other factors such as infusion pump programming defects should always be considered. Worldwide, medication errors have been reported to affect 2-30% of patients, depending on the institution. Intravenous lipid emulsion (ILE) infusion is frequently used as part of total parenteral nutrition in patients of all ages with feeding and gastrointestinal issues...

Hyperprogressive disease (HPD) has been recently proposed as a new pattern of progression in patients treated with immune checkpoint inhibitors (ICIs). Until now, no biological marker has been found to predict this accelerated tumour growth. We describe the case of a 62-year-old women who experienced a marked increase in absolute eosinophil count (AEC) concurrently with a huge radiological progression after the first nivolumab dose in absence of other immune-related adverse events (irAEs). Further investigations are needed to establish the role of early hypereosinophilia as a marker of progression and to identify patients who might not benefit from ICI treatment...
