Apollo 13Exiting re-entry black-out 90 seconds past the expected time because the trajectory kept inexplicably shallowing. The shallowing was determined to be because of the leak from the damaged SM (O2 tank?). As soon as the CM separated from the SM, the shallowing stopped.

Did any of the Apollo guys report losing fingernails? I seem to remember they had problems with blisters from the gloves.

The documents that list the anomalies are the Mission Reports. They are available from NASA's report server or from Bob Andrepont's reborn list here, which is easier to search.

Forgot the dehydration issue when one of them lost their drinking tube (one of 16's crew?) I think that was Jim Irwin during one of the Apollo 15 EVAs. Irwin couldn't drink any water during the first EVA. John Young had a similar problem. He couldn't reach the tube during the first Apollo 16 EVA. In the transcript, he says, "Yes. I could have drank all of mine [water] if I had a mouth behind my left ear. That's my only problem. It got lodged back there and I could never get at it." www.hq.nasa.gov/alsj/a16/a16.eva1post.html

I recall complaints by Cernan in The Last Man on the Moon of painfully skinned knuckles from the pressure suit gloves.

Interesting article. Thanks for uploading. Forget which astronaut it was, but didn't one have breathing difficulties due to the regolith. Is that on the list, or are we talking purely mechanical issues.

Just about every lunar landing mission had a long series of "anomalies" documented in the mission reports. Many of them seem downright trivial, but nothing is really trivial when you're that far from home.
Even if you limit the problems to those that came close to aborting the mission and/or injuring the crew, it's not hard to find one for almost every mission:
Apollo 11 - computer alarms during landing; navigation errors resulting in downrange landing; frozen heat exchanger in SHe loop after landing
Apollo 12 - two lightning strikes after liftoff
Apollo 13 - (special case)
Apollo 14 - Docking problems during T&D; intermittent short in abort switch; late landing radar lock-on
Apollo 15 - shorted SPS control switch; cardiac arrhythmias due to crew fatigue and hypokalemia
Apollo 16 - SPS gimbal problems nearly scrubbed landing
Apollo 17 - ? this is the only one where I can't think of a really serious problem offhand.

Apollo 17 - ? this is the only one where I can't think of a really serious problem offhand. The dust played havoc with the rover and some of the tools. In this article is speaks of the 'breeze'. A new conspiracy theory abound. The HBs will take that as a skip that the nauts were on an Earth moonset.

The shallowing was determined to be because of the leak from the damaged SM (O2 tank?). As soon as the CM separated from the SM, the shallowing stopped. Are you sure? The oxygen was long gone from the service module by those final hours before entry. I'm not saying you're definitely wrong, but I seem to recall hearing it was more likely due to thrust from the LM's cooling sublimator. It's mounted on the upper rear of the ascent stage. In AS11-40-5929 it's visible between the VHF EVA antenna and the aft inflight VHF antenna. A cover mounted on standoffs keeps sunlight from striking the sublimator itself.

I also recall the sublimator as causing the shallowing.

I think it was especially acute with Dave Scott on Apollo 15, as he had intentionally asked for his glove fingers to be a little too short to give him better control of his fingertips. That turned out to be a mistake.

I thought Mattingly was exposed to the Measles and had to be replaced by Swigert? It was Mattingly. Though Mattingly certainly got his due. Not only did he never get sick during the Apollo 13 mission, he got to fly as CMP on Apollo 16 -- which was entirely successful. Right. All three Apollo 13 astronauts were on extremely short water rations, due in part to a misunderstanding with the ground about urine dumps, so they got rather dehydrated. Haise's infection was probably a direct result of this dehydration. He was in pretty bad shape when they got back; I think he missed the early celebrations on the recovery carrier.
