I assume your talking about the Greek revolt and the 2 Egyptian wars involving the Ottoman Empire. The Greek revolt was nearly beaten OTL, and it would have been if it wasn't for the intervention of the western powers. However, if they didn't intervene and the rebels were fully crushed, expect Nationalism to be a weaker force in the Balkans, and the image of the Ottoman empire crumbling may be less pervasive then OTL.
As for the Egyptian situation, it wasn't a revolution on the part of the Egyptian people, mearly a war against the Ottomans by a rebellious vassal, Muhammed Ali Pasha. Though if the Ottomans beat him and take Egypt over (a big stretch, the Ottomans struggled against Muhammed militarily, and the powers are unlikely to help them take Egypt, for various reasons), then expect a stronger empire in the 19th century. Egyptian cotton should alleviate at least some of the money worries that plauged the late Ottoman empire, and if the Suez canal or a similar one is built, the Ottomans should get a bit of diplomatic sway over the British, because of its key position on the way to India.
