Validating Dose Rate Calibration Of Radiotherapy Photon Beams Through Iaea/Who Postal Audit Dosimetry Service, Abdul Qadir Jangda, Sherali Hussein

Department of Radiation Oncology

In external beam radiation therapy (EBRT), the quality assurance (QA) of the radiation beam is crucial to the accurate delivery of the prescribed dose to the patient. One of the dosimetric parameters that require monitoring is the beam output, specified as the dose rate on the central axis under reference conditions. The aim of this project was to validate dose rate calibration of megavoltage photon beams using the International Atomic Energy Agency (IAEA)/World Health Organisation (WHO) postal audit dosimetry service. Three photon beams were audited: a 6 MV beam from the low-energy linac and 6 and 18 MV beams from …

St Elevation: Telling Pathology From The Benign Patterns, Waleed Tallat Kayani, Henry D. Huang, Salman Bandeali, Salim S. Virani, James M. Wilson, Yochai Birnbaum

Office of the Provost

Benefits of early reperfusion in patients presenting with acute ST elevation myocardial infarction (STEMI) are well known. The American College of Cardiology / American Heart Association guidelines recommend triage decisions are made within 10 minutes of performing initial electrocardiogram (ECG). Since many patients presenting with ischemic symptoms may have ST elevation (STE) at baseline, not all STE signify transmural ischemia. Benign patterns can be easy to find in some cases. However, patients with benign STE at baseline (left ventricular hypertrophy, early repolarization pattern) may have ongoing ischemia and present with Non-ST elevation myocardial infarction (NSTEMI) or even STEMI superimposed on …

A Comparative Analysis Of Toluidine Blue With Frozen Section In Oral Squamous Cell Carcinoma, Montasir Junaid, Moaz M. Choudhary, Zain A. Sobani, Ghulam Murtaza, Sadaf Qadeer, Naeem S. Ali, Mumtaz J. Khan, Anwar Suhail

Department of Surgery Docs

Background:Surgical excision of the primary tumor with safe margins remains the mainstay of treatment for oral cavity squamous cell carcinoma (OSCC). The standard of care for assessment of intraoperative margins is frozen section histopathology. Unfortunately the facility is not available at most centers in limited resource countries. Toluidine blue, a metachromatic dye, has been well described in clinical identification of malignant and premalignant lesion in the oral cavity. Considering this we decided to explore intraoperative use of toluidine blue staining, in comparison with frozen sections, for the assessment of tumor-free margins.

Methods:

After obtaining clearance from the in-house ethical …

Minimally Invasive Endoscopic Selective Parathyroidectomy, Montasir Junaid, Zainul Abedeen Sobani, Maliha Kazi, Mumtaz Junaid Khan

Section of Otolaryngology, Head & Neck Surgery

Primary hyperparathyroidism is a common condition with surgery being the definitive treatment modality. Controversy exists over the extent of optimal neck exploration, whether unilateral or bilateral exploration should be performed, particularly since 85-90% of primary hyperparathyroidism results from single gland disease. Unilateral neck exploration is now considered to be adequate unless a definitive adenoma is not identified on ipsilateral exploration and where the serum intact Parathyroid Hormone (iPTH) level does not show a decline greater than 60% after removal of a suspected adenoma. It also avoids the potential risk of hypocalcaemia, recurrent laryngeal nerve injury along with extended anaesthesia and …
