Introduction: Many patients treated with intravenous immunoglobulin (IVIg) are >60 years of age. Tolerability has yet to be demonstrated in this age group., Methods: This is a retrospective study of adverse reactions among consecutive patients treated with IVIg for neurological disorders. Risk factors were recorded. Correlation and relative risks were calculated for age, risk factors, IVIg course, daily dose, concentration, preparation, and duration of treatment. An infusion and monitoring protocol was applied., Results: Two hundred forty-four patients were reviewed, including 62% who were ≥60 years of age (total dose 1.8 ± 0.4 g/kg body weight, daily dose 30.3 ± 2.0 g). Sixty-nine percent received sugar-stabilized IVIg. Forty-nine percent presented with >1 risk factor. Adverse reactions occurred in 35% and led to treatment discontinuation in 5%, with a similar incidence among age groups. In patients ≥60 years old, sucrose-free IVIg administration was an independent predictor of adverse reactions, including renal failure., Conclusion: In the elderly, IVIg infusions are safe. Adverse reactions mainly depend on IVIg preparation and administration. Renal failure is not uncommon with sugar-free IVIg., (© 2016 Wiley Periodicals, Inc.)

Background: Headache is the most frequent symptom in cerebral venous thrombosis (CVT), and usually the first. However, it has rarely been reported as the only symptom of CVT., Objectives: To study the characteristics of patients in whom headache was the only presentation of CVT in the absence of intracranial hypertension, subarachnoid haemorrhage (SAH), meningitis, or other intracranial lesion., Methods: From a prospective study of 123 consecutive patients with CVT only those with isolated headache and normal brain computed tomography (CT) scan and cerebrospinal fluid (CSF) examination were included in the present study. All patients underwent an extensive systematic aetiological work-up and were given intravenous heparin followed by oral anticoagulants. A detailed description of the headache was obtained., Results: Headache was only sign of CVT in 17 patients. The lateral sinus was the most frequently involved sinus (n = 15). Onset of headache was progressive in 11, acute in 3, and thunderclap in 3 patients. Once established, the headache was continuous in 15, diffuse in four and unilateral in 13, usually ipsilateral to the occluded lateral sinus. No specific risk factor or cause was found. All had a favourable evolution., Conclusion: The pathogenesis of isolated headache in CVT in the absence of intracranial hypertension, SAH, meningitis or intracerebral lesion is unknown but may involve changes in the walls of the occluded sinus. Hence MRI/MRV should be used to look for signs of CVT in all patients with recent headache (progressive or thunderclap) even when the CT scan and CSF examination are normal.

We report a patient with headaches meeting the criteria of chronic paroxysmal hemicrania, as defined by the International Headache Society classification. Headaches were fully responsive to indomethacin during the first 3 months of treatment but recurred when daily doses were lowered. Investigations revealed a macroprolactinoma. Headaches stopped after cabergoline treatment. This report further suggests that patients with paroxysmal hemicrania should be investigated for pituitary abnormalities. [ABSTRACT FROM AUTHOR]
