2.  Low cholesterol as a risk factor for primary intracerebral hemorrhage: A case–control study 
An inverse association between serum cholesterol and the risk of hemorrhagic stroke has been noted in epidemiological studies. We performed a case–control study to assess the relationship between primary intracerebral hemorrhage (ICH) and low serum cholesterol.
Materials and Methods:
Prospectively recruited fully evaluated patients with ICH were compared with a control group based in a primary care practice, i.e. age- and sex-matched individuals attending the routine preventive health check-up. Low cholesterol was defined by the sex-specific lowest quintile of the population.
The proportion of ICH patients with low cholesterol was significantly higher than the controls (68% vs. 43%). Mean total cholesterol was also signficantly low in ICH patients compared with controls (177 mg/dL vs. 200 mg/dl; P-value = 0.0006). Low-density lipoprotein cholesterol (LDL-c) and triglycerides were also significantly low in ICH patients compared with controls. Mean LDL-C in the ICH patient group was 114 mg/dL, whereas it was 128.5 mg/dL in the control group (P-value = 0.016). There was no significant difference in the high-density lipoprotein (HDL) levels in both groups. In a subgroup analysis, both men and women in the ICH group had a significantly low mean cholesterol compared with the control group. Although lower mean cholesterol was seen in both young and older individuals in the ICH group than in controls, the difference was significant only in the older group (age >45 years). In multivariate analysis, presence of low cholesterol remained a significant predictor of hemorrhage. The odds ratio of low cholesterol in the hemorrhage cases was 2.75 (95% CI = 1.44–5.49) unadjusted and 2.15 (1.13–4.70) adjusted for age and hypertension.
This study confirms an increased risk of primary ICH associated with low cholesterol both in men and women, especially in older individuals.

3.  Primary Sjögren's syndrome manifesting as multiple cranial neuropathies: MRI findings 
We report a case of primary Sjögren's syndrome presenting with multiple cranial nerve palsies and radiological evidence of cranial pachymeningitis and hypophysitis. A 47-year-old woman developed right sensory neural hearing loss followed, 2 months later, by right facial palsy. Cranial magnetic resonance imaging showed features of pachymeningitis and pituitary gland infiltration. The diagnosis of primary Sjögren's syndrome was confirmed by demonstrating positive SS-A and SS-B antibodies and histological evidence of lymphocytic infiltration of the sublabial salivary gland. During the 2-year follow-up, the patient had transient VIth, IXth, Xth, and XIIth cranial nerve palsies. Sjögren's syndrome should be considered in the differential diagnosis of patients presenting with multiple recurrent cranial nerve palsies, even if prominent sicca symptoms are absent.
