Tnf-Α Promotes Nuclear Enrichment Of The Transcription Factor Tonebp/Nfat5 To Selectively Control Inflammatory But Not Osmoregulatory Responses In Nucleus Pulposus Cells., Zariel I. Johnson, Alexandra C. Doolittle, Joseph W. Snuggs, Irving M. Shapiro, Christine L. Le Maitre, Makarand V. Risbud

Department of Orthopaedic Surgery Faculty Papers

Intervertebral disc degeneration (IDD) causes chronic back pain and is linked to production of proinflammatory molecules by nucleus pulposus (NP) and other disc cells. Activation of tonicity-responsive enhancer-binding protein (TonEBP)/NFAT5 by non-osmotic stimuli, including proinflammatory molecules, occurs in cells involved in immune response. However, whether inflammatory stimuli activate TonEBP in NP cells and whether TonEBP controls inflammation during IDD is unknown. We show that TNF-α, but not IL-1β or LPS, promoted nuclear enrichment of TonEBP protein. However, TNF-α-mediated activation of TonEBP did not cause induction of osmoregulatory genes. RNA sequencing showed that 8.5% of TNF-α transcriptional responses were TonEBP-dependent and …

Sex Differential In 15-Hydroxyprostaglandin Dehydrogenase Levels In The Lumen Of Human Intracranial Aneurysms., Nohra Chalouhi, Pascal Jabbour, Mario Zanaty, Robert M. Starke, James Torner, Daichi Nakagawa, David M. Hasan

Department of Neurosurgery Faculty Papers

BACKGROUND: Aspirin is a promising medical therapy for the prevention of intracranial aneurysm (IA) rupture. Recently, we found that men have a better response to aspirin than women. The purpose of this study was to determine whether a sex differential exists in the level of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) in the lumen of human IAs.

METHODS AND RESULTS: Consecutive patients undergoing coiling or stent-assisted coiling for a saccular IA at our institution were enrolled. Two samples (A and B) were collected from IA lumens, and the plasma level of 15-PGDH was measured using an ELISA-based method. The study included 38 patients, …

Hematoma In The Bucco-Mandibular Space: First Case Report., Joe Iwanaga, Charlotte Wilson, Emre Yilmaz, Cameron K Schmidt, Rod J Oskouian, R Shane Tubbs

Articles, Abstracts, and Reports

Our previous studies based on intraoral dissection of fresh cadavers revealed that the fissure and loose connective tissues deep to the mucosa between the incisivus labii inferioris muscle and buccinator muscle form the entrance of the newly discovered bucco-mandibular space. To support the clinical significance of this space, we report the finding of a hematoma within this space in an adult fresh cadaver. Such a finding lends credence to studying the bucco-mandibular space and might help better understand the spread of some infections in the oral region.

Efficiency Of Spinal Anesthesia Versus General Anesthesia For Lumbar Spinal Surgery: A Retrospective Analysis Of 544 Patients., John T. Pierce, Guy Kositratna, Mark A. Attiah, Michael J. Kallan, Rebecca Koenigsberg, Peter Syre, David Wyler, Md, Paul J. Marcotte, W. Andrew Kofke, William C. Welch

Department of Anesthesiology Faculty Papers

BACKGROUND: Previous studies have shown varying results in selected outcomes when directly comparing spinal anesthesia to general in lumbar surgery. Some studies have shown reduced surgical time, postoperative pain, time in the postanesthesia care unit (PACU), incidence of urinary retention, postoperative nausea, and more favorable cost-effectiveness with spinal anesthesia. Despite these results, the current literature has also shown contradictory results in between-group comparisons.

MATERIALS AND METHODS: A retrospective analysis was performed by querying the electronic medical record database for surgeries performed by a single surgeon between 2007 and 2011 using procedural codes 63030 for diskectomy and 63047 for laminectomy: 544 …

Delayed Spinal Cord Infarction Following Anterior Cervical Surgical Decompression, Muhammad Faheem Khan, Rashid Jooma, Fauzan Alam Hashmi, Muhammad Faraz Raghib

Section of Neurosurgery

Anterior cervical discectomy and fusion (ACDF) for cord compression is a safe and effective procedure with good outcomes. However, worsening of myelopathy is the most feared adverse event of the surgery. We report the case of a 36-year-old male patient who presented with an acute non-traumatic C5-6 cervical disc herniation causing incomplete quadriparesis. He underwent an uncomplicated ACDF at C5-6, and after an initial period of improvement, he developed a delayed onset of an anterior cord syndrome on day 3, without any discerning cause. We have reviewed similar cases reported in the literature and believe that our patient's postsurgical course …

Cadaveric Study For Intraoral Needle Access To The Infratemporal Fossa: Application To Posterior Superior Alveolar Nerve Block Technique., Joe Iwanaga, Emily Simonds, Rod J Oskouian, R Shane Tubbs

Articles, Abstracts, and Reports

The posterior superior alveolar (PSA) nerve block is, from an anatomical perspective, challenging because the mandibular ramus and the zygomatic process of the maxilla can interfere with the course of the needle. Dentists empirically know that shifting the patient's mandible to the ipsilateral side can improve visibility and accessibility for such blocks. This cadaveric study aimed to establish anatomical evidence for the ipsilateral mandible shifting used in the PSA. The distance between the lateral most bulging point of the alveolar part of the maxilla and ipsilateral anterior border of the ramus of the mandible ranged from 1.4 to 6.9 mm …

Necrotizing Fasciitis Of The Neck: Case Presentation, Emil Marginean, Ciprian Venter, Maria Domuta, Oana Valenas, Ildiko Sorban, Alina Pantis, Bogdan Popescu, Razvan V. Scăunașu

Journal of Mind and Medical Sciences

Necrotizing fasciitis represents a severe and rare infectious disease, which is accompanied by extended necrosis of subcutaneous tissues and fascia layers, having as a result gangrene of the teguments. To reduce mortality associated with this disease, a rapid diagnosis is necessary as well as aggressive surgical treatment, accompanied by adequate, aggressive antibiotic therapy. As a rule, etiology is teeth related, with the condition more common in immunology-depressed patients. This article presents the experience of the authors regarding a case presentation of necrotizing fasciitis with typical clinical expression and management of the disease in an immunological-depressed patient. Further data on diagnosis, …

Zenker’S Diverticulum And Squamous Esophageal Cancer: A Case Report, Ion Dina, Octav Ginghina, Corina D. Toderescu, Cristian Bălălău, Bianca Galateanu, Carolina Negrei, Claudia Iacobescu

Journal of Mind and Medical Sciences

Zenker’s diverticulum represents a rare esophageal lesion developed especially in the elderly population due to herniation of esophageal mucosa above the cricopharyngeus muscle. The condition leads to food retention, regurgitation, aspiration, and dysphagia in affected patients. Progressive dysphagia also characterizes malignant diseases of the esophagus like squamous esophageal carcinoma that typically appears in male patients in the seventh decade of life, with a history of cigarette smoking and alcohol abuse. We report a case of a male patient who presented with dysphagia for both solids and liquids along with significant weight loss, and who was diagnosed with medium esophageal cancer …

The Psychological Influence Of The Diagnosis Of Breast Cancer On Therapeutic Options Selection, Razvan V. Scaunasu, Stefan Voiculescu, Bogdan Popescu, Cristina Cozma, Radu Jecan, Cristian Balalau

Journal of Mind and Medical Sciences

The therapeutic management decision-making process for breast cancer is complex, and is influenced by multiple factors including patient age, comorbidities, ethnicity, education, and availability of immediate or delayed reconstruction options. Our study analysed 276 patients diagnosed with breast cancer in the “Colțea” Clinical Hospital between 2014 and 2015. Mean patients age was 61.24, median 62, with a range of 31 to 89 years. Younger age was associated with a less advanced local disease and younger patients were more likely to choose and benefit from conservative surgery. Most patients (61.76%) came from rural areas. Place of origin had a significant influence …

Emergency Surgery And Limitation Of Therapeutic Effort In Relation To Neurologic Deterioration In Elderly Patients – A Survey Of European Surgeons, Mihai Paduraru, Luca Ponchietti, Isidro M. Casas, Jorge Pereira, Aitor Landaluce-Olavarria, Diego Mariani

Journal of Mind and Medical Sciences

Background. In emergency surgery, a very heterogeneous approach is required in the decision making process, especially when considering the patient’s postoperative quality of life as well as medical, ethical, and legal factors. In some cases, the presence of an Advance Directive (AD) form may potentially help resolve the surgeon’s dilemma. Objectives. The primary objective of this survey was to investigate the opinions of surgeons across a representative cross-section of European countries regarding the decision making process using a specific case scenario so as to identify similarities and differences in practice. A secondary objective was to identify the possibility of establishing …

End-Stage Head And Neck Cancer: Coping Mechanism, Bogdan Popescu, Oana Paun, Razvan V. Scăunaşu, Serban V.G. Berteşteanu

Journal of Mind and Medical Sciences

Coping mechanisms are patients’ means of adapting to stressful situations and involve psychological and physical changes in behavior. Patients adapt to head and neck cancer in a variety of ways. Head and neck cancers are extremely debilitating, especially in advanced stages of the disease or in end-of-life situations. While an oncology team needs to address the needs of all oncology patients, the advanced terminal patients require special attention. Most of these patients do not cope well with their situation and have a tendency to cease social interactions. Pain is the most frequentlyexperienced medical disability in patients having an end-stage illness …

Direct Insertion Of The Papillary Muscle Into The Anterior Mitral Leaflet: Cadaveric Findings., Sarvenaz Sheikh, Joe Iwanaga, Jocelyn R Gonzales, Tsuyoshi Saga, Marios Loukas, Rod J Oskouian, R Shane Tubbs

Articles, Abstracts, and Reports

Direct insertion of the anterior papillary muscle (DPM) into the mitral valve is uncommon. During the routine dissection of an adult female, a DPM into the mitral valve with abnormal chordae tendinae was observed. This abnormal papillary muscle was measured as 28.0 mm in length from myocardial to insertion, 14.8 mm in width, and 7.0 mm in depth. The embryology, symptoms, associated cardiac diseases, and surgical precautions of this congenital malformation in the heart are reviewed.

Robust Head Ct Image Registration Pipeline For Craniosynostosis Skull Correction Surgery, Shusil Dangi, Hina Shah, Antonio Porras, Beatriz Paniagua, Cristian Linte, Marius George Linguraru, Andinent Enquobahrie

Radiology Faculty Publications

Craniosynostosis is a congenital malformation of the infant skull typically treated via corrective surgery. To accurately quantify the extent of deformation and identify the optimal correction strategy, the patient-specific skull model extracted from a pre-surgical computed tomography (CT) image needs to be registered to an atlas of head CT images representative of normal subjects. Here, the authors present a robust multi-stage, multi-resolution registration pipeline to map a patient-specific CT image to the atlas space of normal CT images. The proposed registration pipeline first performs an initial optimisation at very low resolution to yield a good initial alignment that is subsequently …

Pancreaticogastrostomy - An Alternate For Dealing With Pancreatic Remnant After Pancreaticoduodenectomy - Experience From A Tertiary Care Center Of Pakistan, Tabish Chawla, Hassaan Bari, Shahrukh Effendi

Section of General Surgery

Whipple's pancreaticoduodenectomy has been refined over the years to be a safe operation though the morbidity rate still remains high (30-50%). Pancreatic fistula is the most important cause of mortality following pancreaticoduodenectomy. To prevent it, surgeons have used two anastomotic techniques: pancreaticojejunostomy and pancreaticogastrostomy. Recent studies found that pancreaticogastrostomy is associated with fewer overall complications than pancreaticojejunostomy. This is a retrospective review of patients who underwent Whipple's at Aga Khan University Hospital and had pancreaticogastrostomy as a preferred anastomosis for pancreatic stump. Forty four patients met the inclusion criteria, 27 were male. No patient developed post-operative pancreatic fistula, 13 (31%) …

Development Of A Unifying Target And Consensus Indicators For Global Surgical Systems Strengthening: Proposed By The Global Alliance For Surgery, Obstetric, Trauma, And Anaesthesia Care (The G4 Alliance), Adil H. Haider, John W. Scott, Colin D. Gause, Mira Meheš, Grace Hsiung, Albulena Prelvukaj, Dana Yanocha, Lauren M. Baumann, Faheem Ahmed, Asad Latif

Section of General Surgery

After decades on the margins of primary health care, surgical and anaesthesia care is gaining increasing priority within the global development arena. The 2015 publications of the Disease Control Priorities third edition on Essential Surgery and the Lancet Commission on Global Surgery created a compelling evidenced-based argument for the fundamental role of surgery and anaesthesia within cost-effective health systems strengthening global strategy. The launch of the Global Alliance for Surgical, Obstetric, Trauma, and Anaesthesia Care in 2015 has further coordinated efforts to build priority for surgical care and anaesthesia. These combined efforts culminated in the approval of a World Health …

Role Of 5-Ala In Improving Extent Of Tumour Resection In Patients With Glioblastoma Multiforme, Muhammad Waqas, Inamullah Khan, Muhammad Shahzad Shamim

Section of Neurosurgery

Goal of surgery for patients with Glioblastoma Multiforme (GBM) is gross total resection with no new neurological deficits. Surgical resection is often restricted due the difficulty in differentiating the tumour from surrounding normal brain using either naked eye, or standard intra-operative white light microscopy. GBM uptakes orally administered 5-ALA becomes fluorescent when viewed by a special light, and this property has been used to improve intra-operative tumour identification. This technique should therefore allow better extent of tumour resection. The hypothesis has been tested through several studies and even though most studies are of low quality, they strongly favour the use …

Video Microscope Robotic Arm-Assisted, Neuronavigation-Guided Glioma Resection And Regional Sampling, Muhammad Waqas, Ather Enam, Fauzan A Hashmi, Fatima Mubarak, Fazal Arain

Section of Neurosurgery

High-grade gliomas possess internal pathological heterogeneity. Selective sampling of different tumor regions can help in the study of this heterogeneity. In this report, we have described the use of a novel navigation and optical system for the selective regional sampling of a high-grade glioma lesion. A 45-year-old gentleman presented to us with complaints of intermittent frontal headaches for past eight months. On examination, he had subtle pyramidal weakness in left upper and lower extremities. Magnetic resonance imaging (MRI) showed a large contrast-enhancing, space-occupying lesion in the right frontal lobe causing perilesional edema and midline shift. We marked four different regions …
