Fungal infection of the feet can be succesfully treated, but it often recurs.
This apple is red, but it has a yellow patch.

Can "it" be ommited in the above sentences?

"It" can be omitted in both. If it is omitted, then the commas must be dropped.

QUOTE] 2.
Infectious mononucleosis heals on its own.
Hepatitis A heals by itself.

Both corect?[/QUOTE]

Both are grammatically correct, but I believe that it would be more accurate to write "Infectious mononucleosis heals without treatment.

3.
He and I were late.
Him and me were late.

Both appropriate?

"Him" and "me" are objective forms and can not be used as subjects of a sentence.

4.
It is not wise to eat a lot before bed.
Eating a lot before bed is not wise.

Is starting sentences with "it" not recommended?

Starting a sentence with "it" is perfectly fine, as long as the sentence is otherwise well constructed.

1. Yes, "it" can be omitted.
2. Both are correct.
3. The first is correct (He was late; I was late); the second is not, but is what uneducated or sloppy people might well say, and so could be appropriate in dialogue depending on who says it.
4. I don't believe there is any taboo against beginning sentences with "it".

The thing about starting a sentence with 'it' is that 'it becomes the subject. The subject of your sentence looks to be about eating before bed rather than about wiseness, so I'd say the best way to start it would be 'Eating before bed..."

Of course, you *can* start sentences with 'it', but unless used well, the sentence can lose the strength of its subject.

Can "it" be ommited in the above sentences? Yes. Omitting the 'it' makes them slightly harder sentences to read, but they still make sense.

2.
Infectious mononucleosis heals on its own.
Hepatitis A heals by itself.

Both corect? Yes

3.
He and I were late.
Him and me were late.

Both appropriate?
We were late.

4.
It is not wise to eat a lot before bed.
Eating a lot before bed is not wise.

Is starting sentences with "it" not recommended?
Depends who's doing the recommending. I'd prefer the first of those two sentences.

#1

I don't see the pronoun as necessary in those sentences.

#2

Diseases don't heal. People with infections heal. That said, both of those seem a tad colloquial for a scientific or medical journal.

Trying to sound super formal, I come up with: "Infectious mononucleosis can be defeated by a patient's autoimmune system without the aid of additional medication."

#3

He, She, Who and I are the subjective case, meaning that they perform the verb in a sentence.

Him, Her, Whom, and Me are the objective case, meaning that they're the "target of a verb."

Native speakers confused by pronoun case can usually figure a complicated or confusing instance by testing whether it sounds right, but this is far from fool proof.

Him and me were late.
Him was late?
Me was late?

Remember that the SUBJECTive case is always the subject, though, and you'll be fine.

#4

It is not wise to eat a lot before bed.
Eating a lot before bed is not wise.

Starting with It can be confusing; I'd avoid it. The it construction is easy to write though - so often, just to keep writing, one can use it and then tighten up the writing later, in a revision.

All the above comments are good.

To which I'll append:

"ommited" is not correct.

Neither is "corect".

More on #4:

In your example, 'He and I' is grammatically correct. It is also grammatically correct to say, for example, 'Harry threw the water balloon at John and me'. In a way it doesn't sound right, and your parents would probably tell you to say 'John and I' but in fact this is not correct. The easiest way to test this rule is to drop the other person from the sentence. 'Harry threw the water balloon at me' is obviously correct, 'Harry threw the water balloon at I' is obviously not. As in your example, you would never say 'Me was late' or 'Him was late'.
