Primary intraosseous meningioma of the calvarium: A systematic review.

BACKGROUND: Primary intraosseous meningiomas (PIM) of calvarial origin are a small subset of meningiomas that arise from and occur within the calvarial bone. Its definition is often confused with other forms of non-dural based intracranial meningiomas, which has made previously published retrospective reviews heterogenous, non-specific and sometimes inaccurate. We present a systematic review of calvarial PIM. METHODS: Using a systematic search protocol that included databases such as PubMed, Web of Science and Embase, we extracted all human studies on PIM published from inception to December 2017. This systematic review includes case reports and retrospective reviews that specifically described PIM. RESULTS: On review of 166 articles identified with the systematic search protocol, 69 articles were analyzed. These comprised of 64 case reports, 1 case series and 4 retrospective reviews. 111 patients with PIM of calvarial origin were analyzed, 58 % of which were females and 42 % males. The mean patient age was 51 years and the frontal bone was the most common tumor location, occurring in 26.1 % of the cases. Surgical resection was the predominant modality of treatment in 97.2 % of the cases, and gross total resection was achieved in 84 % of cases that reported extent of resection. There were no recurrences for grade I meningiomas. However, all grade III meningiomas recurred and 33.3 % of grade II meningiomas showed recurrence with a mean postoperative follow-up interval of 20 months. Statistical analysis using Fisher's exact test showed the recurrence rate to be strongly associated with WHO tumor grade (p-value <0.001). CONCLUSION: There is statistically significant increased recurrence rate for calvarial PIM of higher grades, and we recommend close follow-up in those cases. Surgical resection remains the overwhelming treatment of choice for calvarial PIM, and it has a high gross total resection rate and low risk of complications and mortality.

A comparative survey for assessing Rashidabad city hospitals quality with District Headquarter Hospital.

Patients are the key stakeholders of any hospital and it is important to satisfy them. The objective of this study was to compare the quality of hospitals within Rashidabad; a town in rural Sindh operated by Rashid Memorial Welfare Organization (RMWO), with District Headquarter hospital Tando Allahyar. A cross sectional survey, based on a questionnaire designed in congruence with literature, regarding the hospital quality was conducted on 150 patients in October 2016. The target population was defined as patients getting treatment at hospitals within Rashidabad; whose estimate was reported by RMWO as 2000 per week. Hospital quality index (HQI) was framed in the light of quality of staff, ward, pain management practices and hygiene which includes food. Logistic Regression was applied on HQI that showed dependence of perception about hospital quality on age, hospital location and patient's health. Results were significantly in favour of hospitals within Rashidabad.

Diastolic blood pressure predicts coronary plaque volume in patients with coronary artery disease.

BACKGROUND AND AIMS: Hypertension is associated with increased clinical and subclinical coronary artery disease (CAD); however, the relationship between blood pressure and coronary plaque volume is unclear. We examined the effect of systolic blood pressure (SBP) and diastolic blood pressure (DBP) on coronary artery plaque volume. METHODS: 285 subjects with stable CAD on statin therapy underwent coronary computed tomographic angiography to measure volume of fatty, fibrous, noncalcified, calcified and total coronary plaque. RESULTS: Mean (SD) age was 63.1 (7.7); mean (SD) LDL-C, 78.7 mg/dL (28.5). Compared to the highest DBP tertile (>76 mmHg), those in the lowest DBP tertile (≤68 mmHg) had lower volumes of fatty: 10.0 vs. 7.7 mm3/mm, (p trend = 0.042), fibrous: 19.6 vs. 13.8 mm3/mm (p trend = 0.011), non-calcified: 29.7 vs. 22.5 mm3/mm (p trend = 0.017) and total plaque: 37.8 vs. 25.1 mm3/mm (p trend = 0.010) whereas there was no relationship with SBP tertiles. Similarly, when examined as a continuous variable, higher DBP was a significant independent predictor of higher plaque volume after multivariate adjustment: for every 1 mmHg increase in DBP, fibrous plaque increased 0.128 mm3/mm (p = 0.022), noncalcified plaque increased 0.176 mm3/mm (p = 0.045), calcified plaque increased 0.096 mm3/mm (p = 0.001) and total plaque increased 0.249 mm3/mm (p = 0.019) whereas SBP ranging from 95 to 154 mmHg did not predict plaque volume. CONCLUSIONS: Level of DBP predicts coronary plaque with a DBP tertile ≤68 mmHg associated with the least amount of coronary plaque in subjects with LDL-C < 80 mg/dL.

Effect of Eicosapentaenoic and Docosahexaenoic Acids Added to Statin Therapy on Coronary Artery Plaque in Patients With Coronary Artery Disease: A Randomized Clinical Trial.

BACKGROUND: Although statins reduce cardiovascular events, residual risk remains. Therefore, additional modalities are needed to reduce risk. We evaluated the effect of eicosapentaenoic acid and docosahexaenoic acid in pharmacologic doses added to statin treatment on coronary artery plaque volume. METHODS AND RESULTS: A total of 285 subjects with stable coronary artery disease on statins were randomized to omega-3 ethyl-ester (1.86 g of eicosapentaenoic acid and 1.5 g of docosahexaenoic acid daily) or no omega-3 (control) for 30 months. Coronary plaque volume was assessed by coronary computed tomographic angiography. Mean (SD) age was 63.0 (7.7) years; mean low-density lipoprotein cholesterol ≤80 mg/dL. In the intention-to-treat analysis, our primary endpoint, noncalcified plaque volume, was not different between groups (P=0.14) but approached significance in the per protocol analysis (P=0.07). When stratified by age in the intention-to-treat analysis, younger omega-3 subjects had significantly less progression of the primary endpoint, noncalcified plaque (P=0.013), and fibrous, calcified and total plaque. In plaque subtype analysis, controls had significant progression of fibrous plaque compared to no change in the omega-3 ethyl-ester group (median % change [interquartile range], 5.0% [-5.7, 20.0] versus -0.1% [-12.3, 14.5], respectively; P=0.018). Among those on low-intensity statins, omega-3 ethyl-ester subjects had attenuation of fibrous plaque progression compared to controls (median % change [interquartile range], 0.3% [-12.8, 9.0] versus 4.8% [-5.1, 19.0], respectively; P=0.032). In contrast, those on high-intensity statins had no difference in plaque change in either treatment arm. CONCLUSIONS: High-dose eicosapentaenoic acid and docosahexaenoic acid provided additional benefit to statins in preventing progression of fibrous coronary plaque in subjects adherent to therapy with well-controlled low-density lipoprotein cholesterol levels. The benefit on low-intensity statin, but not high-intensity statin, suggests that statin intensity affects plaque volume. CLINICAL TRIAL REGISTRATION: URL: http://www.ClinicalTrials.gov.
