Open Fractures Caused By High Velocity Missiles: The Outcome Of Treatment Of 39 Fractures Followed For 1-3 Years, M A. Khan, R Hussain, S H. Khan, M Umar

Department of Surgery Docs

Between 1993 and 1995, thirty-three patients having 39 fractures caused by missiles fired from a high velocity rifle were reviewed retrospectively between 1 and 3 years after injury and the outcome of treatment assessed. Majority (33 out of 39) were Grade III. Union was achieved in 35 out of 39 fractures, there was deep infection and delayed union in one case each. Non-union occurred in three fractures. The fractures were stabilized using different techniques, but highest complication rate was seen with the use of the static external fixator. This was related to the severe nature of the injury as well …

The Optimal Fontan Connection: A Growing Extracardiac Lateral Tunnel With Pedicled Pericardium., S R. Gundry, A J. Razzouk, M J. Del Rio, Girish S. Shirali, L L. Bailey

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: The concept of a lateral tunnel for the Fontan operation is now widely accepted. Most lateral tunnels are constructed intraatrially with the use of aortic crossclamping. Construction of extracardiac lateral tunnels with the use of homografts or other nonviable tubes eliminates aortic crossclamping but lacks growth potential in length or width. The native pericardium, which is "sealed" posteriorly along the pulmonary artery, atrium, and inferior vena cava, could be turned down onto the right atrium to form a viable extracardiac lateral tunnel.

METHODS: We designed and successfully constructed extracardiac lateral tunnels using viable autologous pericardium, pedicled on its lateral …

Method For Employing The Delta Opioid Dadle To Extend Tissue Survival Time During Ischemia, Sufan Chien

Surgery Faculty Patents

This invention concerns a method for extending the survival time of mammalian lung tissue subjected to ischemia, by which said tissue is perfused with a preservation solution comprising a therapeutic dose of the delta opioid DADLE ([D-Ala²,D-Leu⁵]-Enkephalin) under hypothermic conditions.

Fine Needle Aspiration Cytology In Parotid Lumps, A Zafar, M Shafi, S H. Hassan, S Malik

Section of Otolaryngology, Head & Neck Surgery

Over a period of two years, Fine Needle Aspiration Cytology (FNAC) was performed on 33 patients presenting with a parotid lump. Five patients were excluded as they were treated medically after FNAC report. The FNAC results of 28 cases were compared with histopathological diagnoses of surgically resected specimens. There were 8 true positive, 17 true negative, 1 false positive and 2 false negative cases. Sensitivity was 80%, specificity 94.4% and diagnostic accuracy 89.3%. FNAC is a simple quick, accurate and virtually complications free investigative modality. It is also helpful adjunct to assess preoperatively the suitability and extent of the surgical …

Mirizzi Syndrome Type Ii: Is Laparoscopic Cholecystectomy Justified?, D C Desai, R D Smink

Department of Surgery Faculty Papers

Mirizzi syndrome type II is an uncommon cause of obstructive jaundice caused by an inflammatory response to an impacted gallstone in Hartmann's pouch or the cystic duct with a resultant cholecystocholedochal fistula. Two cases of Mirizzi syndrome type II are presented. Clinically only one patient had jaundice and endoscopic retrograde cholangiopancreatogram (ERCP) established a preoperative diagnosis of Mirizzi syndrome. The other patient's diagnosis of Mirizzi syndrome was made intraoperatively. It is important to properly identify the anatomy at the time of surgery to avoid compromising the common bile duct. Operative treatment of Mirizzi syndrome type II includes laparoscopic or open …

Endothelial Nitric Oxide Synthase And Growth Factor Regulation Of Flow-Mediated Vascular Remodeling, David Anthony Tulis

Theses and Dissertations in Biomedical Sciences

This study was designed to characterize structural remodeling of male Wistar rat mesenteric arteries exposed to elevated blood flow in vivo for 1, 3, or 7 days. A series of arterial ligations induced blood flow increases in ileal and second-order branch arteries compared to same animal control vessels. Neither mean carotid nor local mesenteric arterial pressures changed significantly pre- to post-ligation. The primary flow-mediated force in both vessels was shear stress with possible involvement of acute stretch-induced wall stress in the ileal artery. Significant luminal expansion and medial wall hypertrophy occurred in the ileal and second-order arteries in a time-dependent …

Ambulatory Arthroscopic Knee Surgery Results Of Partial Meniscectomy, Muhammad Umar

Section of Orthopaedic Surgery

In an open prospective study the results of arthroscopic partial meniscectomy were reviewed in 188 knees. Group I comprised of 139 (65%) knees with pure meniscus lesions without any ligament laxity, the remaining 49 (35%) knees in group II had anterior cruciate ligament (ACL) deficiency in addition to meniscus lesions. In group I, 93% had excellent to good and 7% had fair results by criteria of Tapper and Hoover. In group II, 75% had excellent to good and 25% had fair results. Arthroscopic knee surgery was a good method of identifying patients in group II who required anterior cruciate reconstruction. …

Axotomy And Regeneration Of The Rat Facial Nerve: A Histomorphometric Study Of The Facial Nucleus, Nerve And Orbicularis Oculi Muscle In An Experimental Model Of Facial Paralysis, Peter Konstantinos Thanos

Theses and Dissertations in Biomedical Sciences

One of the most unsettling sequela of facial paralysis (FP) is the loss of eye sphincter function and the blink response, leading to functional, psychological and aesthetic deficits. A medley of restorative microsurgery approaches have been employed in treating these deficits, however full recovery of function remains elusive. The present research utilized the rat model of facial paralysis, and consisted of three stages. Stage I examined the facial motor neuron (FMN) pool of the eye sphincter (orbicularis oculi muscle=OOM) and identified the facial nerve branch which provides the majority of innervation to the OOM. II. Examined the efficacy of the …
