Stem Cells For Spinal Cord Regeneration: Current Status, Zain A. Sobani, Syed A. Quadri, Ather Enam

Section of Neurosurgery

Background: Nearly 11,000 cases of spinal cord injury (SCI) are reported in the United States annually. Current management options give a median survival time of 38 years, however, no rehabilitative measures are available. Stem cells have been under constant research given their ability to differentiate into neural cell lines replacing non functional tissue. Efforts have been made to establish new synapses and provide a conducive environment, by grafting cells from autologous and fetal sources, including embryonic or adult stem cells, Schwann cells, genetically modified fibroblasts, bone stromal cells, and olfactory ensheathing cells and combinations/ variants thereof.
Methods: In order to …

Microdiscectomy For Lumbosacral Disc Herniation And Frequency Of Failed Disc Surgery, Muhammad Shahzad Shamim, Maria Adnan Parekh, Muhammad Ehsan Bari, Ather Enam, Faraz Khursheed

Section of Neurosurgery

Background: Microdiscectomy for lumbosacral disc herniations is one of the most commonly performed neurosurgical procedures. The Patient demographics, symptomatology, and recovery are highly variable, and surgical outcomes depend on several factors, including Patient demographics. Failed disc surgery refers to failure of improvement in Patient's symptoms following microdiscectomy, and has been observed to occur in up to 12% of Patients. To date, no study form Pakistan has looked into Patient demographics and failed disc surgery rates within the local context.
Objective:The aim of this study was to review the demographics of the Patient population presenting for surgical treatment of lumbosacral …

Portable Ultrasonography In Mass Casualty Incidents: The Caveat Examination, Stanislaw P. Stawicki, James M. Howard, John P. Pryor, David P. Bahner, Melissa L. Whitmill, Anthony J. Dean

Department of Surgery Faculty Publications

Ultrasonography used by practicing clinicians has been shown to be of utility in the evaluation of time-sensitive and critical illnesses in a range of environments, including pre-hospital triage, emergency department, and critical care settings. The increasing availability of light-weight, robust, user-friendly, and low-cost portable ultrasound equipment is particularly suited for use in the physically and temporally challenging environment of a multiple casualty incident (MCI). Currently established ultrasound applications used to identify potentially lethal thoracic or abdominal conditions offer a base upon which rapid, focused protocols using hand-carried emergency ultrasonography could be developed. Following a detailed review of the current use …

Cardiac Surgery In Octogenarians, Asmatullah Khan, Hassan Khan, Saulat H. Fatimi, Asadullah Khan

Section of Cardiothoracic Surgery

In Europe and North America, cardiac surgery can be done successfully on octogenarians, but differences in patient selection, surgical and bypass techniques prevent us from concluding similarly in Pakistan. This study investigated the short and long-term outcomes of cardiac surgery in octogenarians operated over a 5 years period at The Aga Khan University Hospital, from January 2001 to December 2006. Seventeen octogenarians, (mean age 81.7 ± 2.3) underwent coronary artery bypass graft (CABG). Thirty-days hospital mortality was reported in only 1 patient. Surgical complication of any kind was reported in 13 (76.5%) patients with pleural effusion being the commonest in …

Grown Up Congenital Heart Disease Patient Presenting For Non Cardiac Surgery: Anaesthetic Implications, Mohammad Hamid, Mansoor Ahmed Khan, Mohammad Irfan Akhtar, Hameedullah, Saleemullah, Khalid Samad, Fazal Hameed Khan

Department of Anaesthesia

Congenital heart disease patients surviving to adulthood have increased over the years due to various reasons. These patients are admitted in the hospital for non cardiac surgeries and other procedures more often than normal adult population. Management of grown up congenital heart disease patient presents a challenge during perioperative period for cardiologists, surgeons, intensivists and particularly for the anaesthetist. Management issues include psychological and physiological impact on the patient, complexity of defects, presence of previous palliative procedure, impact of anaesthetic agents on shunting and myocardium, endocarditis prophylaxis and associated extra cardiac anamolies.

Pp32 (Anp32a) Expression Inhibits Pancreatic Cancer Cell Growth And Induces Gemcitabine Resistance By Disrupting Hur Binding To Mrnas., Timothy K Williams, Christina L Costantino, Nikolai A Bildzukewicz, Nathan G Richards, David W Rittenhouse, Lisa Einstein, Joseph A Cozzitorto, Judith C Keen, Abhijit Dasgupta, Myriam Gorospe, Gregory E Gonye, Charles J Yeo, Agnieszka K Witkiewicz, Jonathan R Brody

Department of Surgery Faculty Papers

The expression of protein phosphatase 32 (PP32, ANP32A) is low in poorly differentiated pancreatic cancers and is linked to the levels of HuR (ELAV1), a predictive marker for gemcitabine response. In pancreatic cancer cells, exogenous overexpression of pp32 inhibited cell growth, supporting its long-recognized role as a tumor suppressor in pancreatic cancer. In chemotherapeutic sensitivity screening assays, cells overexpressing pp32 were selectively resistant to the nucleoside analogs gemcitabine and cytarabine (ARA-C), but were sensitized to 5-fluorouracil; conversely, silencing pp32 in pancreatic cancer cells enhanced gemcitabine sensitivity. The cytoplasmic levels of pp32 increased after cancer cells are treated with certain stressors, …

Should We Be Concerned About Jejunoileal Atresia During Repair Of Duodenal Atresia?, Shawn D. St Peter, Danny C. Little, Katherine A. Barsness, Daniel R. Copeland, Casey M. Calkins, Suzanne Yoder, Steve S. Rothenberg, Saleem Islam, Kuojen Tsao, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: During repair for duodenal atresia, it has been emphasized that inspection of the small bowel to identify a second atresia is required. The laparoscopic approach for repair of duodenal atresia has been criticized for its limitation to perform this step. Given that duodenal atresia and jejunoileal atresias do not share common embryologic origins, we question the validity of this concern. Therefore, we conducted a multicenter retrospective review of duodenal atresia patients to quantify the incidence of jejunoileal atresia in this population.

METHODS: After institutional review board approval (IRB #07-12-187X), a retrospective review was conducted on all patients who have …

Developmental Dysplasia Of The Hip., Shahryar Noordin, Masood Umer, Kamran Hafeez, Haq Nawaz

Department of Surgery Docs

Developmental dysplasia of the hip (DDH) is a spectrum of anatomical abnormalities of the hip joint in which the femoral head has an abnormal relationship with the acetabulum. Most studies report an incidence of 1 to 34 cases per 1,000 live births and differences could be due to different diagnostic methods and timing of evaluation. Risk factors include first born status, female sex, positive family history, breech presentation and oligohydramnios. Clinical presentations of DDH depend on the age of the child. Newborns present with hip instability, infants have limited hip abduction on examination, and older children and adolescents present with …

A Case Study Of Appendicitis At Antanimalandy Lutheran Hospital, Jennifer Gemmell

Independent Study Project (ISP) Collection

From the introduction:

The island of Madagascar houses a total of 19,159,000 people who spend only $34 per person per year on health care (“Madagascar,” 2008). The government claims to have “committed itself to the principle that good health is a right of each Malagasy citizen, and has made significant studies in the area of health care,” according to the country study for the Library of Congress. However, with political corruption, political crisis after political crisis, and lack of international support, the government does not dispense the funds necessary to support this commitment (Metz, 1994). For example, in 1976 the …
