Ocular prosthesis following plastic surgery

The shape of the eye prostheses depends on the plastic surgery type. Standard prostheses with thin but not sharp edges are used to recreate the conjunctival cavity, prostheses with a deep retraction or flat ones are employed for a delayed introduction into the stump, prostheses with a 'swelling' at the upper edge are of use in surgery to correct the upper eyelid falling in, prostheses with a flattened lower edge and a 'shelf' at the upper edge are used to fortify the lower eyelid. Individual prostheses are recommended after plastic surgery. The prostheses should not prevent free closing and blinking of the eyelids, retaining the identical opening of the eyes. An inadequately chosen prosthesis brings to nothing the tremendous work made by the surgeon. Ocular prosthetics may be regarded as the final stage stabilizing the results of plastic surgery.     

Hemodynamic effects of the treatment of hypertension with the calcium channel blocker diltiazem

The 1.5-benzotthazepine derivative diltiazem, which blocks slow calcium channels, is an effective hypotensive agent, used for the treatment of moderate hypertension. Treatment with diltiazem alone, its dose adjusted on an individual basis, controlled arterial blood pressure in 58% of the patients. With a 240 mg daily dose, blood pressure was controlled in 12 of 52 patients; when the daily dose was increased to 360 mg, blood pressure was controlled in another 18 patients. In the remaining 22 patients, blood pressure was only controlled after captopril was added in a daily dose of at least 50 mg. The drop of arterial blood pressure was associated with falling total peripheral resistance and end diastolic blood volume, and was accompanied by an increase in left-ventricular ejection fraction and myocardial oxygen want.
