Recurrent Painful Ophthalmoplegic Neuropathy Responding to Lamotrigine: A Case Report.

Recurrent painful ophthalmoplegic neuropathy (RPON) is a rare neurological disorder characterized by recurring ipsilateral headache and paresis of one or more ocular motor nerves. We report the case of a 56-year-old woman with systemic lupus erythematosus (SLE) and hypertension, who presented with severe recurring headaches, nausea, and vomiting. Initially misdiagnosed with cerebral venous sinus thrombosis, her symptoms persisted despite anticoagulant therapy. Further evaluation led to the diagnosis of RPON. Management included intravenous analgesia, hydration, and indomethacin for pain relief. Persistent headache episodes necessitated the introduction of lamotrigine, resulting in significant symptom improvement. However, discontinuation of lamotrigine led to a recurrence of symptoms, which resolved upon resuming the medication. This case contributes to the limited RPON literature, providing insights into its diagnosis and management, with the goal of enhancing awareness and improving patient care.

Characteristics and predictors of mortality of patients with hematologic malignancies requiring invasive mechanical ventilation.

RATIONALE: Acute respiratory failure (ARF) may complicate the course of hematologic malignancies (HMs). Our objective was to study the characteristics, outcomes and predictors of mortality of patients with HMs who required intubation for ARF. METHODS: This retrospective cohort study evaluated all patients with HMs who were admitted to the Intensive Care Unit (ICU) of King Abdul-Aziz Medical City-Riyadh between 2008 and 2013 and required invasive mechanical ventilation. We noted their baseline characteristics, treatments and different outcomes. Multivariable logistic regression analysis was performed to evaluate predictors of hospital mortality. RESULTS: During the 6-year period, 190 patients with HMs were admitted to the ICU and 122 (64.2%) required intubation for ARF. These patients had mean age of 57.2 ± 19.3 years and Acute Physiology and Chronic Health Evaluation II score of 28.0 ± 7.8 and were predominantly males (63.4%). Lymphoma (44.3%) and acute leukemia (38.5%) were the most common hematologic malignancy. Noninvasive ventilation (NIV) was tried in 22 patients (18.0%) but failed. The code status was changed to "Do-Not-Resuscitate" for 39 patients (32.0%) during ICU stay. Hospital mortality was 70.5% and most deaths (81.4%) occurred in the ICU. The mortality of patients with "Do-Not-Resuscitate" status was 97.4%. On multivariable logistic regression analysis, male gender (odds ratio (OR), 6.74; 95% confidence interval (CI), 2.24-20.30), septic shock (OR, 6.61; 95% CI, 1.93-22.66) were independent mortality predictors. Remission status, non-NIV failure and chemotherapy during ICU stay were not associated with mortality. CONCLUSIONS: Patients with HMs requiring intubation had high mortality (70.5%). Male gender and presence of septic shock were independent predictors of mortality.
