Stigmata of diseases

What does stigmata mean?

Stigmata means some lesion, mostly skin, which is visible, showing the patient is suffering from that particular disease.
In some diseases, like leprosy and tuberculosis, the patient may not want to reveal the condition because of the stigmata associated with the disease in society. But due to certain signs, the disease gets revealed. (These diseases were considered a disgrace in earlier days.)

Thyroid carcinoma mnemonic

Hello! 
I made a real easy way of remembering thyroid tumors :)

Papillary carcinoma mnemonic:
Popular (Most common thyroid cancer)
Palpable lymph nodes (Lymphatic metastasis is common)
Positive I (131) uptake
Post radiation in head and neck (One of the causes)
Pops out of the capsule (Usually encapsulated but invades capsule)
Pops everywhere in the gland (Multifocal)
Positive, pleasing, perfect, parexcellence, peerless prognosis
(Excellent prognosis because it's slow growing)
[Another mnemonic is PG - Papillary, Good prognosis =D ]
Histology:
Popping eyes (Clear nuclei, Orphan Annie Eyes)
Papillary pattern
Psammoma bodies
Pseudoinclusions (Intranuclear cytoplasmatic inclusions)

Study group discussion: Why more phenytoin is prescribed at night

Why do we give phenytoin in 1-0-2 dose after discharge? Why two tablets at night?

Phenytoin causes marked drowsiness that can confound the mental status (read GCS) exam in medicated patients, most critically those who have had neurosurgery and are given phenytoin for postoperative seizure control. In an outpatient being prescribed phenytoin one would plausibly order more to be taken when the patient is likely to be asleep instead of when they're awake.

Thank you for sharing this with us.

One article says, previously, we used to give 300 mg once daily. After chronic use, patients started developing adverse reactions of drug. It was then decided to start using phenytoin in divided doses. (100 mg TID).

Also remember that gingival hyperplasia is a very important and distinctive secondary effect of phenytoin, my teachers say that it stays even if you stop the medicine, but I'm not sure of that since I have not read that anywhere else.
