It was there that, in 1939, his son Antonietto died as a result of a badly performed appendectomy.
The same year, he was made a Professor of Modern Literature at the University of Rome.
If left untreated, a severe tooth abscess may become large enough to perforate bone and extend into the soft tissue eventually becoming osteomyelitis and cellulitis respectively.
The rod of Asclepius, a snake-entwined staff, remains a symbol of medicine today
NEVER USE THE WORD CAVITY
He was the son of Apollo and Coronis. His mother was killed for being unfaithful to Apollo and was laid out on a funeral pyre to be consumed, but the unborn child was rescued from her womb. ... From this he received the name Asklepios "to cut open".
Openings in the tooth enamel allow bacteria to infect the center of the tooth (the pulp). Infection may spread out from the root of the tooth and to the bones supporting the tooth.
Apollo carried the baby to the centaur Chiron who raised Asclepius and instructed him in the art of medicine.
Infection results in a collection of pus (dead tissue, live and dead bacteria, white blood cells) and swelling of the tissues within the tooth. This causes a painful toothache. If the pulp of the tooth dies, the toothache may stop, unless an abscess develops.
Ophiuchus is located between Aquila, Serpens and Hercules, northwest of the center of the Milky Way. The southern part lies between Scorpius to the west and Sagittarius to the east. In the northern hemisphere, it is best visible in summer. It is located opposite Orion in the sky. Ophiuchus is depicted as a man grasping a serpent; the interposition of his body divides the snake constellation Serpens into two parts, Serpens Caput and Serpens Cauda, which are nonetheless counted as one constellation.
The main symptom is a severe toothache. The pain is continuous and may be described as gnawing, sharp, shooting, or throbbing.
Other symptoms may include:
Bitter taste in the mouth
General discomfort, uneasiness, or ill feeling
Pain when chewing
Sensitivity of the teeth to hot or cold
Swollen glands of the neck
Swollen area of the upper or lower jaw -- a very serious symptom
L'IMPIETRITO E IL VELLUTO
Ho scoperto le barche che molleggiano
Sole, e le osservo non so dove, solo.
Non accadrà le accosti anima viva.
Impalpabile dito di macigno
Ne mostra di nascosto al sorteggiato
Gli scabri messi emersi dall'abisso
Che recano, dondolo nel vuoto,
Del vecchissimo ossesso
La eco di strazio dello spento flutto
Durato appena un attimo
Sparito con le sue sinistre barche.
Mentre si avvicendavano
L'uno sull'altro addosso
I branchi annichiliti
Dei cavalloni del nitrire ignari,
Il velluto croato
Dello sguardo di Dunja,
Che sa come arretrarla di millenni,
Come assentarla, pietra
Dopo l'aggirarsi solito
Da uno smarrirsi all'altro,
Zingara in tenda di Asie,
Il velluto dello sguardo di Dunja
Fulmineo torna presente pietà.
