Objective Ketamine has been shown to decrease sedative requirements in intensive care unit (ICU). Randomized trials are limited on patient-centered outcomes. We designed this pilot trial to evaluate the feasibility of a large randomized controlled trial (RCT) testing the effect of ketamine as an adjunct analgosedative compared with standard of care alone as a control group (CG) in critically ill patients with mechanical ventilation (MV). We also provided preliminary evidence on clinically relevant outcomes to plan a larger trial. Material and methods Pilot, active-controlled, open-label RCT was conducted at medical, surgical, and transplant ICUs at a large tertiary and quaternary care medical institution (King Faisal Specialist Hospital and Research Center, Saudi Arabia). The study included adult patients who were intubated within 24 h, expected to require MV for the next calendar day, and had institutional pain and sedation protocol initiated. Patients were randomized in a 1:1 ratio to adjunct ketamine infusion 1–2 μg/kg/min for 48 h or CG alone. Results Of 437 patients screened from September 2019 through November 2020, 83 (18.9%) patients were included (43 in CG and 40 in ketamine) and 352 (80.5%) were excluded. Average enrollment rate was 3–4 patients/month. Consent and protocol adherence rates were adequate (89.24% and 76%, respectively). Demographics were balanced between groups. Median MV duration was 7 (interquartile range [IQR] 3–9.25 days) in ketamine and 5 (IQR 2–8 days) in CG. Median VFDs was 19 (IQR 0–24.75 days) in ketamine and 19 (IQR 0–24 days) in the CG (p = 0.70). More patients attained goal Richmond Agitation–Sedation Scale at 24 and 48 h in ketamine (67.5% and 73.5%, respectively) compared with CG (52.4% and 66.7%, respectively). Sedatives and vasopressors cumulative use, and hemodynamic changes were similar. ICU length-of-stay was 12.5 (IQR 6–21.2 days) in ketamine, compared with 12 (IQR 5.5–23 days) in CG. No serious adverse events were observed in either group. Conclusions Ketamine as an adjunct analgosedative agent appeared to be feasible and safe with no negative impact on outcomes, including hemodynamics. This pilot RCT identified areas of improvement in study protocol before conducting a large, adequately powered, multicenter RCT which is likely justified to investigate ketamine association with patient-centered outcomes further.

Lupus erythematosus panniculitis (LEP) is a rare variant of cutaneous lupus erythematosus (CLE). It is characterized by the presence of a chronic inflammatory process involving the deep dermis and subcutaneous tissues. It commonly presents as deep indurated nodules or sharply demarcated plaques. Antimalarial medications are considered first-line therapy for most cases of LEP while systemic corticosteroids are saved for more resistant lesions. Intravenous immunoglobulin (IVIG) is made up of concentrated polyclonal immunoglobulin G (IgG) fractionated from the blood of healthy blood donors. Nowadays, it is used for the treatment of numerous autoimmune and systemic inflammatory diseases. In this case, we report the case of a female with multiple LEP and discoid lupus erythematosus (DLE) lesions refractory to multiple standard therapy modalities that responded dramatically to IVIG.

Chordomas are rare tumors believed to be originated from notochordal remnants. Of all intracranial neoplasms, the incidence of cranial chordomas is less than 1%1. The youngest patient with an intracranial chordoma reported in the literature was a newborn in the first few days after birth9. Intracranial chondroma are more predominant in males compared to females1. The clinical features of intracranial chondroma in the pediatric age group commonly include increased Intracranial pressure, lower cranial nerves palsy, and torticollis2. There is no optimum treatment, however, surgical resection of the tumor followed by radiation therapy reported successful outcome3. This is a case of a poorly differentiated clival chordoma of a 23-month old boy. The clinical features, pathological, radiological findings, and surgical technique are discussed with an elaboration of the current review of the literature of clival chordoma in the extreme young age group. To the best of our knowledge, this is the youngest age of clivus chordoma reported in Saudi Arabia.
