Oculogyric Crisis Following Dosage Increase of Aripiprazole: A Case Report.

Oculogyric crisis (OGC) is a form of acute dystonia with involuntary conjugated ocular gaze in a fixed position. Common causes include metabolic disorders and medications, primarily typical antipsychotics. A 24-year-old male with a history of persistent depressive disorder and possible bipolar disorder was admitted to the psychiatric unit due to suicidal ideation. He was started on aripiprazole 5 mg and subsequently increased to 10 mg due to uncontrolled mood disorder. The patient subsequently developed OGC, which resolved with benztropine and diphenhydramine. This case report highlights aripiprazole-induced OGC and prompt management with benztropine and first-generation antihistamines.

Rotational Atherectomy in Acute Coronary Syndrome: A Meta-Analysis.

BACKGROUND: The use of rotational atherectomy (RA) in percutaneous coronary intervention (PCI) of acute coronary syndrome (ACS) is considered relatively contraindicated. There have been several observational studies showing RA use in ACS, however, no systemic studies have been undertaken. We sought to evaluate the feasibility and outcomes of RA PCI in ACS by performing a meta-analysis. METHODS: We searched PUBMED, EMBASE, CINAHL, and Cochrane Central Register of Clinical Trials for any studies that evaluated the role of RA PCI in ACS. The outcomes analyzed were all-cause mortality, cardiac mortality, short and long-term major adverse cardiac events (MACE), procedural complications and cardiac perforations. RESULTS: There was a total of 8 retrospective studies with a total population of 1237 with a median follow up of 23 months. The median age of the included patient was 73. Angiographic success rate was 97.4%. The rate of all-cause mortality and cardiac mortality were 5% (range 1-12%, p < 0.001, I2 = 92%) and 2% (range 0-5%, P = 0.03, I2 = 58%) respectively. In-hospital MACE and long-term MACE were 7% (range 3-13%, p < 0.001, I2 = 87%) and 29% (range 21-37%, p = 0.21, I2 = 34%) respectively. The incidence of total procedural complications was noted to be 7% (range 2-14%, p < 0.001, I2 = 90%). Rate of perforation was 1% (range 0-1%, p = 0.9, I2 = 0%). CONCLUSION: Our results show that RA PCI is feasible in ACS with comparable procedural complications and short-term MACE, but with a higher long-term MACE rate compared to RA PCI in routine cases.

Prophylactic Low-Molecular-Weight Heparin Versus Unfractionated Heparin in Spine Surgery (PLUSS): A Pilot Matched Cohort Study.

BACKGROUND: Despite a proven superior efficacy of prophylactic low-molecular-weight heparin (LMWH) over unfractionated heparin (UFH) in the majority of surgical specialties, chemoprophylactic techniques after spine surgery have not been established because of the fear of epidural hematomas with LMWH. OBJECTIVE: To determine the efficacy of LMWH vs UFH in the prevention of venous thromboembolism (VTE) events, balanced against the risk of epidural hematoma. METHODS: This is the first matched cohort design that directly compares prophylactic LMWH to UFH after spine surgery for degenerative/deformity pathologies at a tertiary academic center. Prospectively collected patients receiving prophylactic LMWH and a historical cohort of patients receiving prophylactic UFH (prior to 2017) were matched in 1:1 ratio based on age ±5 yr, American Society of Anesthesiologists classification, location in the spinal column, and type of surgery. RESULTS: Of 562 patients, VTE events equaled 1.4% (n = 8): 1.4% (n = 4) with LMWH was exactly equal to 1.4% (n = 4) with UFH. Epidural hematomas reached 0.8% (n = 5): 1.4% (n = 4) with UFH vs 0.3% (n = 1) with the LMWH (P = .178). Utilizing adjusted odds ratio (ORadj), the type of chemoprophylaxis after spine surgery failed to predict VTE events. Similarly, the chemoprophylactic technique failed to predict epidural hematoma in the multivariable regression analysis, although UFH trended toward a higher complication rate (ORadj = 3.15 [0.48-20.35], P = .227). CONCLUSION: Chemoprophylactic patterns failed to predict VTE. Although no differences in epidural hematoma rates were detected, our analysis does highlight a trend toward a safer profile with LMWH vs UFH. LMWH may be a safe alternative to UFH in spine surgery.
