Moyamoya disease is a rare clinical disorder, characterized by chronic, progressive occlusion of supraclinoid internal carotid artery and proximal portions of the anterior and middle cerebral arteries, and consequent development of collateral vessels seen on imaging as puff of smoke appearance. Although the pathophysiology is unclear, various hematologic disorders have been associated with development of the moyamoya syndrome. We report a case of moyamoya syndrome in a 3 yr old girl who presented with recurrent ischemic strokes. The angiography was suggestive of moyamoya syndrome. The serum vitamin B12 level was remarkably low with bone marrow picture of megaloblastic anemia. There was also hyperhomocysteinemia. Moyamoya syndrome has not been previously reported to be associated with vitamin B12 defi ciency. We propose that vitamin B12 defi ciency with hyperhomocysteinemia could result in greater risk for arterial thrombosis and thus caused the moyamoya syndrome in our patient

PURPOSE: The present study was conducted to evaluate the impact of scaling and root planing (SRP) on the C-reactive protein (CRP) levels of gingival crevicular fluid (GCF) and serum in chronic periodontitis patients with type 2 diabetes mellitus (T2DM-CP) or without type 2 diabetes mellitus (NDM-CP). METHODS: Forty-eight human participants were divided into two groups: an experimental (T2DM-CP) group (group I, n=24) comprising chronic periodontitis patients with random blood sugar > or =200 mg/dL and type 2 diabetes mellitus, and control (NDM-CP) group (group II, n=24) of those with chronic periodontitis and random blood sugar <200 without T2DM for the study. All subjects underwent nonsurgical periodontal therapy (NSPT) including complete SRP and subgingival debridement. Periodontal health parameters, plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), GCF volume (GCF vol), GCF-CRP, random blood glucose (RBS), glycated hemoglobin, and systemic inflammatory markers, serum CRP, total leukocyte count (TLC), neutrophil count (Neutr) and lymphocyte count (Lymph), were evaluated at baseline, 1 month, and 3 months after SRP. RESULTS: NSPT resulted in statistically significant improvement in periodontal health parameters (PI, GI, PPD, CAL, GCF vol), CRP levels in serum as well as GCF of both groups I and II. The mean improvement in periodontal health parameters (PI, GI, PPD, CAL, GCF vol), CRP levels in serum and GCF was greater in group I than group II after NSPT. There was nonsignificant increase in GCF-CRP, TLC, Lymph, and RBS, and a significant increase in Neutr and Serum CRP in group II at 1 month. The Serum CRP level of 20 out of 24 group II patients had also increased at 1 month. CONCLUSIONS: The CRP levels in both GCF and serum were higher in T2DM-CP patients than in NDM-CP patients. Although there was a significant improvement in both the groups, greater improvement was observed in both GCF and serum samples of T2DM-CP patients.
