Is it safe to wash your anus with water and your (ungloved) hand after pooping, assuming (of course) that you don't touch anything with your hand until you wash it with soap and water?

I'm currently traveling in India. It's common here, instead of using toilet paper after deification, to pour water down your back and use your left hand to wipe your anus clean of feces. I googled to find information from medical professionals to understand if this is safe or not, but I (surprisingly) couldn't find any information on the Internet about this.

Of course, let's assume that we're doing this properly:

1. You only use one hand (typically your left hand), so feces only contaminates one hand.
2. You don't touch anything in the bathroom (eg pitcher, faucet, door knob, etc) with your soiled left hand until after you wash your hands
3. You wash your hands properly, following best-practices: using soap and water, scrubbing vigorously for at least 20 seconds.

I'm less interested in your personal opinion, and more interested if any studies have been done analyzing the efficacy of safety in this scenario, using a proper scientific study.

Have any studies been done to analyze if it's safe to wipe your ass with your hand (and wash your hands properly with soap and water after)?

What are the differences between the different types of Alkaline Phosphatase (ALP) tests for laboratory blood work?

I went to a medical laboratory to get yearly blood work done. In addition to testing for some specific "me" things that I'm monitoring, I want to get a CMP (Comprehensive Metabolic Panel).

I'm in a foreign country where I don't really speak the language. When I said that I wanted blood work done at the lab, the agent at the front desk handed me a form with a lot of boxes to choose what I wanted to get. There is no "CMP" option, so I tried to tick the boxes for the 14 blood tests that compose a CMP, but I got stuck when I tried to check the box for the ALP (Alkaline Phosphatase) test – because there were 3 boxes:

1. Fost. Alcalina
2. Fost. Ácida Total
3. Fost. Ac. Prostatica

What are each of these, and which of these three is the "normal" ALP test that should be included in a CMP?

I've been diagnosed with a supraspinatus tendon rupture of about 1.1 x 1.2 mm on the supraspinatus tendon (posterior fibers). Roughly, how big is it in relationship with its global size? Half? 2 thirds? I'm a small guy - 1.6m tall.

Also, does the tendon recover?

I notice my arm is still a little bit anterior rotated and down a bit as well. About a year has passed.

Should I be worried with some kind of arthrosis down the line, because of the position of the humerus on the glenoid cavity?
