Comparative Study of Blood Loss, Quality of Surgical Field and Duration of Surgery in Maxillofacial Cases with and without Hypotensive Anesthesia.

Background: Oral and maxillofacial surgeons are concern about the intraoperative bleeding because blood supply to face is very generous. Increased blood loss may lead to the need for transfusion of blood and blood products and hence patients are exposed to the risks associated with it. Hence, this study was undertaken to compare whether there is any significant difference in blood loss, surgical field and duration of surgery in patients undergoing maxillofacial surgeries with and without hypotensive anesthesia.

Hormone replacement therapy reduces mean 24-hour blood pressure and its variability in postmenopausal women with treated hypertension.

Background: The rate and severity of hypertension increase dramatically after menopause. Complications seem to be more frequent and marked in hypertensive patients with greater blood pressure (BP) variability, and antihypertensive treatment does not easily reduce this variability. The effect of hormone replacement therapy (HRT) on BP and its variability is not well understood in moderate to severe hypertension, but estrogen may have calcium channel-blocking properties.

Zinc, copper and manganese in serum, urine and stones.

Serum zinc, copper and manganese levels were estimated in normal subjects (NS) and stone formers (SF). There was no significant difference in the serum levels of Zn, Cu, and Mn in NS and SF, the values being 101.5 +/- 35.

Sodium is neither a risk nor a protective factor in urolithiasis?

The effect of changes in urinary sodium, induced by dietary manipulation in normal subjects (NS) and in stone formers (SF) was studied by observing crytalluria qualitatively and by determining calcium, oxalate and phosphate crystallization quantitatively in an experimental model. In SF the calcium crystallization was significantly higher than in NS at all the three levels of urinary sodium studied. However, no difference was observed in oxalate and phosphate crystallization rates between these two groups.
