Here is a brief history of those pioneers and milestones. The earliest record of “dental” work dates back to 2600 BC in Egypt. The tomb of Hesy-Ra, an Egyptian scribe, is engraved with “The greatest of those who deal with teeth and of physicians”. Then later, Hippocrates and Aristotle recorded many dental examinations from tooth eruptions sequences to treating decayed teeth and gingiva disease between 500-300 BC. In ancient times tooth decay was thought to be brought on by “tooth worms” in the mouth and there is evidence of the first treatments orally.
There was one particular case during these past six years working at Plainview Oral and Maxillofacial surgery that made me realize my desire to go to dental school. Dr. Barry Bass and I began preparing for a surgical extraction of the left mandibular second molar. The tooth was infected and formed a large cystic fibroma that was eating away at the patients jawbone. Dr. Bass said this was going to be a long and difficult surgery; nevertheless, I was prepared for the challenge. I reviewed the Cone Beam CT scan to see what specific instruments the doctor may want for the surgery, other than the general surgical tray.
The reclassification was due to the special features like enhanced mitotic rate, epithelial budding of basal layer or daughter cysts, chromatid aberrations, PTCH gene mutation. [7,8,9,10,11,12] Studies have shown that Keratocystic odontogenic tumour is more commonly seen in the mandible compared to maxilla (75.58%) with primary site being posterior ramus area followed by the anterior region. Maxillary lesions show predilection to 3rd molar area followed by cuspid. In the above reported case the lesion was in the maxilla extending from the canine to molar area which is a rare site of occurrence. [5, 6, 13, 14] Although it can occur at any age, significant predilection is in second to third decade of life more commonly in male patients.
HE ALSO NOTED THE PRESENCE OF FECERS AND ___________AT THE TIME. HIS PRIMARY CARE PHYSICIAN ORDERED AN ABDOMINAL ULTRASOUND THAT REVEALED THE PRESENCE OF MULTIPLE LIVER LESIONS. A CT SCAN OF THE CHEST, ABDOMEN AND PELVIS CONFIRMED THE PRESECE OF MORE THAN 30 LOW-ATTENUATION LIVER LESIONS AND ENHANCING MASS RISING ROM THE LESSER CURVATURE OF THE STOMACH AND _________________LUMPH NODES ALONG THE ________ LIGAMENT. BIOPSY OF ONE OF THE LIVER LESIONS WAS POSITIVE FOR UNDIFFERENTIATED CARCINOMA. AN ENDOSCOPY WAS SUBSEQUENTLY PERFORMED AND VISUALIZED A LARGE, FUNGATING, ULCERATED MASS ARISING IN THE ________THAT EXTENDED INTO THE GASTRIC BODY IN THE LESSER _______.
He then concluded that the patient was in love with a girl whose home Avicenna was able to pinpoint based on the examination of his pulse. This demonstrates how physicians in the early Islamic period diagnosed certain medical illnesses by using palpitations and the arterial pulse to indicate abnormal heart rate, allowing certain sickness to be treated before reaching late stages. Similarly, regarding the impact of the arterial pulse, the discovery of heart palpitations also affected modern times as it furthered humans’ knowledge on cardiology, which led the way to several new breakthroughs such as physicians to using pulse and palpitation as a diagnosis as well as prognosis. In conclusion, Avicenna’s book The Canon of Medicine was a significant piece of medical work as it educated people through its medical doctrines. The breakthroughs included within the piece impacted not only the understanding of medicine in the pre Islamic civilization but also today.
1950s: Ronchese attempted to activate endogenous fluorescent molecules in tumor tissue to delineate its boundaries more accurately. Between 1940 and 1960: Figge et al. and Rasmussen-Taxdal et al. administered natural porphyrins to patients and tumor-bearing animals in an attempt to more accurately detect tumor tissue by
They each focus on a certain area of medicine. The oldest is known as the “Kahun Gynecology Papyrus” it dates back as far as 1825 BCE. As stated by Sameh M. Arab MD, the papyrus “describes methods of diagnosing pregnancy and the sex of the fetus, toothache during pregnancy, diseases of women, as well as feminine drugs, pastes and vaginal applications.” 3 There are several Papyri, along with the Kahun Gynecological Papyrus, the Edwin Smith papyrus (named for the man who purchased it) focuses on surgical trauma, the Hearst papyrus focuses on prescriptions for ailments including unrinary difficulty, butes, hair and blood, the Brugsch Papyrus closely parallels the Ebers Papryus and includes informationon contraception and fertility, the London Medical Papyrus contains both medical practices and magic used for cures; it focuses on skin and eye conditions as well as bleeding stemming from miscarriage, the Ebers Papyrus is among the oldest remaining medical documents and it focuses on herbal knowledge. The Brugsch Papyrus is more recent and provides parallel passages to the Ebers Papyrus, helping to clarify certain passages of the latter.
The diagnosis of cutaneous eyelid melanoma is confirmed histologically. The management of this medical condition is based on biopsy results and staging. For example, the mainstay treatment of early stage malignant melanoma of the eyelid is surgical excision (Chan, O’Donnell, Whitehead, Ryman, & Sullivan, 2007). On the other hand, Mohs micrographic surgery, is the treatment of choice for melanoma
In 1843, Dr. Edward Maynard was the first dentist to use gum elastics as a technique used to correct jaw alignment. An elastic material would be connected to wiring in the mouth to slowly move the jaw until it was in proper alignment. In 1850, E.J. Tucker elaborated Dr. Maynard‘s idea of using gum elastics to correct jaw alignment. Tucker took rubber tubing, and cut it into small bands that could comfortably fit into the mouth.
Congenital Analgesia has been present in individuals for several centuries, but the first medial case study was not performed until 1932 by Dr. Dearborn, on a man that had referred to himself as a human pincushion. This case study was described as a ‘Case of Congenital Pure Analgesia’ and led to many further studies and the creation of different terms to describe Congenital Analgesia. With access to more sophisticated technology, experiments have now been completed to determine the cause of Congenital Analgesia and allow doctors to have a better understanding of the disorder and its effects on each
