SummaryAngioedema of the face and neck is an uncommon but potentially life-threatening complication of angiotensin-converting enzyme (ACE) inhibitor therapy. This condition is of particular concern to the anaesthetist as it can rapidly progress to upper airway obstruction. We describe the presentation and management of five cases of ACE inhibitor related angioedema, all of which were associated with significant upper airway obstruction.

Singing may cause urobilinogen in a person by releasing some sort of chemicals from brain. The standard average of students that took part in this experiment was 90 students. They were from Bahauddin Zakariya University Multan. They were mostly of age 18 to 22. The aim of this study was to find whether there is any tie-up between singing and urobilinogen level. The student’s opinions were noted after examining their urobilinogen level. We found out that most of the students have 0.1 mg/dL urobilinogen in their urine which is normal.

If someone is too much addicted to singing their brain may release some sort of chemicals that may cause urine in blood (hematuria). The examination was done among 90 students belonging to Bahauddin Zakariya University Multan. It involves testing each and every student and then noting their opinions on singing in a separate form. From the data collected, various results and the relation between singing and blood in urine was derived. Although no link between these two can be seen but hematuria can be regarded as an uncommon disease. It can be due to various causes and can be examined by performing urinalysis test.
