Iatrogenic withdrawal

OBJECTIVE: To investigate the independent risk factors associated with iatrogenic withdrawal syndrome in pediatric intensive care units (PICUs) and to establish receiver operator characteristic (ROC) curve to facilitate the diagnosis of iatrogenic withdrawal syndrome in clinical settings. METHOD: Pediatric patients who received analgesic and sedative medication at a tertiary hospital in the southern Zhejiang region of China between January 2016 and December 2022 were selected for the study...

Polypharmacy is an important issue in older patients affected by dementia because they are very vulnerable to the side effects of drugs'. Between October 2021 and September 2022, we randomly assessed 205 old-aged outpatients. The study was carried out in a Center for Dementia in collaboration with a university center. The primary outcomes were: (1) deprescribing inappropriate drugs through the Beers and STOPP&START criteria; (2) assessing duplicate drugs and the risk of iatrogenic damage due to drug-drug and drug-disease interactions...

Intraoperative acute cardiac tamponade associated with iatrogenic intracardiac perforation from percutaneous interventional cardiac procedures is a rare but potentially catastrophic complication. We report a case of intraoperative acute hemopericardium caused by a left atrial (LA) perforation resulting in cardiac tamponade in a patient undergoing a baffling procedure for the correction of two anomalous pulmonary veins draining into her superior vena cava (SVC) that required continuous pericardiocentesis with autologous blood transfusion via the femoral vein and an emergency intraoperative transfer from the interventional cardiology cath lab to the cardiac operating room for an open sternotomy and primary repair...

BACKGROUND AND OBJECTIVE: Other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OIIA-LPD) are rare but well-known diseases that manifest during or after methotrexate (MTX) administration. Limited information is available on the clinical characteristics of OIIA-LPD of the lung because only a few cases have been reported. Thus, we aimed to assess the incidence and prognosis of patients with OIIA-LPD of the lung. METHODS: Patients with OIIA-LPD of the lung treated at our institution between January 2008 and July 2020 were retrospectively analysed...

OBJECTIVE: To describe seizure activity in juvenile dogs successfully weaned from long-term mechanical ventilation. CASE SERIES SUMMARY: Three juvenile dogs (all approximately 3 months old) underwent long-term mechanical ventilation with IV anesthesia for suspected noncardiogenic pulmonary edema. Within 24 hours of extubation and within 10 hours of discontinuing midazolam continuous infusions, all dogs experienced seizures, which is 1 sign of iatrogenic withdrawal syndrome...

DESIGN AND SETTING: Implementation study in the PICUs at McMaster Children's Hospital (site 1) and London Health Sciences (site 2). PATIENTS: All children under 18 years old admitted to the PICU were eligible for the intervention. INTERVENTIONS: A bundle consisting of: 1) analgesia-first sedation; 2) delirium monitoring and prevention; and 3) early mobilization...

Confirmation bias can impede accurate diagnosis. Since the approval of immune checkpoint inhibitors (ICIs), physicians are on high alert for newly developed immune-related adverse events (irAEs). Therefore, when patients present irAE-like symptoms, there is a risk of confirmation bias leading to overlooked diagnoses. This paper discusses a case of a patient with non-small cell lung cancer treated with nivolumab and topical dexamethasone ointment for an extended period due to oral mucocutaneous irAE. The patient developed adrenal insufficiency, initially considered to be a likely case of pituitary irAE...

Serotonin syndrome (SS) is an iatrogenic, drug-induced clinical syndrome caused by an increase in the intrasynaptic concentration of serotonin. Serotonin plays a significant role in the pathophysiology of migraines. Upregulation of 5-HT2A receptors is found in medication-overuse headache (MOH). Several migraine medications, both preventative and abortive drugs, act on serotonin receptors. We report two patients with chronic migraine who developed MOH. Besides headache, patients had frequent attacks of dizziness, restlessness, irritability, insomnia, excessive sweating, abdominal discomforts and tremors...

OBJECTIVES: Sedation and analgesia for infants and children requiring mechanical ventilation in the PICU is uniquely challenging due to the wide spectrum of ages, developmental stages, and pathophysiological processes encountered. Studies evaluating the safety and efficacy of sedative and analgesic management in pediatric patients have used heterogeneous methodologies. The Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research (SCEPTER) IV hosted a series of multidisciplinary meetings to establish consensus statements for future clinical study design and implementation as a guide for investigators studying PICU sedation and analgesia...

A 66-year-old woman who had received tacrolimus for more than 11 years was admitted with high fever, generalized lymphadenopathy, and persistent gastrointestinal bleeding. Histopathological evaluation of the lymph nodes and colonic mucosa confirmed the diagnosis of Epstein-Barr virus-positive diffuse large B-cell lymphoma. After discontinuation of tacrolimus, the lymphoma did not improve, and low-dose chemotherapy was introduced, which resulted in a recovery of lymphocyte counts and induction of complete remission...

BACKGROUND: Pituitary apoplexy is a neurosurgical emergency and is a known yet rare complication of pituitary macroadenoma. Patients typically present with visual field defects, headache and altered sensorium. There are multiple risk factors for this complication and a thorough drug history is essential to exclude iatrogenic causes of disease. We present an extremely rare case of newly diagnosed pituitary insufficiency unveiled by ibrutinib therapy (a Bruton tyrosine kinase inhibitor)...

INTRODUCTION: This systematic review aimed to evaluate the quality of clinical practice guidelines (CPGs) and recommendations for managing pain, sedation, delirium, and iatrogenic withdrawal syndrome in pediatric intensive care (PICU). The objectives included evaluating the quality of recommendations, synthesizing recommendations, harmonizing the strength of the recommendation (SoR) and the certainty of evidence (CoE), and assessing the relevance of supporting evidence. METHODS: A comprehensive search in four electronic databases (Medline, Embase...

An 80-year-old Caucasian female with a history of rheumatoid arthritis presented with a 6-month history of progressive right upper eyelid ptosis, edema, erythema, and pain. MRI demonstrated a superior orbital mass. An incisional biopsy was performed, and pathologic analysis revealed an atypical lymphoid infiltrate, co-expressing both B and T-cell markers, with a low proliferation rate. Flow cytometry and IgH rearrangement study did not demonstrate any B- or T-cell monoclonal proliferation. Based on these findings, she was diagnosed with an iatrogenic immunodeficiency-associated lymphoproliferative disorder...

BACKGROUND: The US Food and Drug Administration approved the once-monthly injectable extended-release buprenorphine product to treat moderate-to-severe opioid use disorders. The patient in our case report had a liposuction procedure and immediately started having opioid withdrawal symptoms after the procedure. CASE DESCRIPTION: The patient is a 27-year-old African-American woman who injects drugs and has morbid obesity. She enrolled in a medications for addiction treatment program and opted to get treated with extended-release buprenorphine monthly injections...

Tardive dyskinesia (TD) is an iatrogenic cause that occurs after prolonged use of antipsychotic and other dopamine-related medications and is described as repetitive, involuntary movement of muscles in the body. This case report focuses on an 80-year-old man who presented with a medical history encompassing dementia, bilateral blindness, glaucoma, hearing loss, hypertension, and hypercholesterolemia. He visited the clinic with a complaint of experiencing visual hallucinations. Investigations, including a CT head and EEG, revealed normal results, and Risperidone was prescribed...

Prior reports described cases of lymphoproliferative diseases occurring after methotrexate (MTX) administration, which are called methotrexate-associated lymphoproliferative disorders (MTX-LPDs). It has become clear that these lymphoproliferative diseases also occur following treatment with other immunosuppressive drugs, and they have been termed as other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OIIA-LPDs). In most of these cases, the duration of immunosuppressive drugs is very long, on the order of years...

Hypertension rightfully termed as "Silent killer" is associated with increase in morbidity and mortality when left untreated. Calcium channel blockers are the most commonly prescribed first-line anti-hypertensive drugs in India. Calcium channel blockers are known to cause gingival hyperplasia but with lower incidence rates compared to the other two groups causing iatrogenic gingival overgrowth, immunosuppressants, and anticonvulsants. Nifedipine administration, among the calcium channel blockers, has been frequently associated with iatrogenic gingival hyperplasia...

Placement of a percutaneous nephrostomy (PCN), to drain and preserve renal function, is a common urologic procedure in the setting of high urinary obstruction. Colonic perforation is a rare complication, with an incidence of 0.2-0.5%. In these situations, literature advises the withdrawal of the PCN into the colon, ureteral stenting, zero-diet, broad spectrum antibiotics and only to remove the catheter days after. Here we describe the case of a patient in whom a PCN was placed transversing the colon, in whom it was retrieved under endoscopic control, with use of endoclips to control the hemorrhage and close the perforation...

A 53-year-old man undergoing painless colonoscopy for long-term diarrhea. After colonoscopy withdrawing to the sigmoid colon, a local perforation was found, about 3 cm in size, oval in shape. We used a two-channel endoscope and grip to pull the edges of the intestinal wall on both sides of the perforation site to close together, and then repair the 3 cm oval perforation of the colon through multiple ordinary titanium clips. The patient had no obvious infection after surgery and recovered well after 1 month of follow-up...
