Are these sentence's punctuated correctly?

Mrs. Smith came to the hospital accompanied by her husband, Mr. Smith, and their youngest daughter.

I will keep you informed, Dr. Smith, about Joe's status here in therapy.

Terry Brazelton, MD, is an expert in pediatrics.

Yes, again except for your question (see your other "Grammar" post).

Are these sentences punctuated correctly?

I am sorry about that. Thanks for your help. =)

This pleasant patient has been seen for therapy from February 2 2005, to March 2 2005.

Naturally, if the need arises, I would be happy to see him again.

=( I am really sorry again. Looks like it just might be a long day for me.

You need a comma between the date and the year. Example:April 14, 2009, was his birthday.

Don't be sorry about the grammar mistakes in the question; it was just another sentence to be corrected.

Yes, these sentences are punctuated correctly.

In the first sentence, the use of commas is correct. Commas are used to set off nonessential information. In this case, information about Mr. Smith being the husband of Mrs. Smith is nonessential to the sentence and can be set off with commas.

In the second sentence, the use of commas is correct. The name "Dr. Smith" is used as an appositive, which is a word or phrase that renames or identifies the noun that precedes it. The commas are used to set off the appositive from the rest of the sentence.

In the third sentence, the use of commas is correct. The name "Terry Brazelton, MD" is used as a parenthetical element that adds additional information about the subject. The commas are used to set off this additional information from the rest of the sentence.
