A Rare Case Of Metastases From A High-Grade Astrocytoma To The Pleura, Bones, And Liver Within Six Months Of Diagnosis, Jennifer L. Dotson, Ala Nijim, Krista L. Denning, Yousef R. Shweihat, Yehuda Lebowicz Aug 2018

A Rare Case Of Metastases From A High-Grade Astrocytoma To The Pleura, Bones, And Liver Within Six Months Of Diagnosis, Jennifer L. Dotson, Ala Nijim, Krista L. Denning, Yousef R. Shweihat, Yehuda Lebowicz

Internal Medicine

High grade astrocytomas such as anaplastic astrocytoma and glioblastoma multiforme are aggressive central nervous system malignancies with a poor prognosis. Due to shortened survival times, their devastating effects are usually localized intracranially and rarely metastasize outside of the central nervous system. When metastases occur, they usually present in patients with longer survival times and they typically coincide with a primary site recurrence. We present a rare case of metastases from a high-grade astrocytoma/glioblastoma to the pleura, bones and liver within six months of diagnosis, without primary site recurrence.

Exploring The Excluded Stomach: A Case Series Of Novel Endoscopic Techniques To Diagnose Gastric Cancer In The Excluded Stomach After Roux-En-Y Gastric Bypass Surgery, Saeed Ali, Abdelkader Chaar, Wesam Frandah, Rola Altoos, Zeeshan Sattar, Muhammad Hasan Jun 2018

Exploring The Excluded Stomach: A Case Series Of Novel Endoscopic Techniques To Diagnose Gastric Cancer In The Excluded Stomach After Roux-En-Y Gastric Bypass Surgery, Saeed Ali, Abdelkader Chaar, Wesam Frandah, Rola Altoos, Zeeshan Sattar, Muhammad Hasan

Internal Medicine

Gastric cancer is the fifth most common malignancy worldwide and the fourth leading cause of cancer-related deaths. The diagnosis is usually made by direct visualization with supporting histopathology. However, patients with gastric bypass surgery pose a challenge in diagnosis due to the difficulty in the evaluation of the excluded stomach. We present two cases of gastric cancer in the excluded stomach after Roux-en-Y gastric bypass (RYGB) surgery was diagnosed using two different endoscopic approaches.


Urinothorax Caused By Xanthogranulomatous Pyelonephritis, Waiel Abusnina, Hazim Bukamur, Zeynep C. Koc Jun 2018

Urinothorax Caused By Xanthogranulomatous Pyelonephritis, Waiel Abusnina, Hazim Bukamur, Zeynep C. Koc

Internal Medicine

Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis that generally afflicts middle-aged women with a history of recurrent urinary tract infections. Its pathogenesis generally involves calculus obstructive uropathy and its histopathology is characterized by replacement of the renal parenchyma with lipid filled macrophages. This often manifests as an enlarged, nonfunctioning kidney that may be complicated by abscess or fistula. This case details the first reported case of xanthogranulomatous pyelonephritis complicated by urinothorax, which resolved on follow-up chest X-ray after robot-assisted nephrectomy.

Gastric Calcifying Fibrous Tumor Mimicking Gi Stromal Tumor, Nneoma Okoronkwo, Shima Ghavimi, Ravi Chokshi, Stephen Peters, Sushil Ahlawat

Internal Medicine

A 27-year-old female with no significant medical history was referred for an EUS to evaluate a large, firm, gastric mass, which was detected during esophagastroduodenoscopy done for persistent reflux symptoms and intermittent epigastric pain. EUS revealed a polypoid, broad-based, solid intramural mass, 2 cm x 4 cm in size, heterogeneous in echo-texture with calcifications and post-acoustic shadowing. The polypoid gastric mass appeared to arise from the muscularis propria.


The Role And Safety Of Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration In The Diagnosis And Management Of Infected Bronchogenic Mediastinal Cysts In Adults, Hazim S. Bukamur, Emad Alkhankan, Haitem Mezughi, Nancy J. Munn, Yousef R. Shweihat Apr 2018

The Role And Safety Of Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration In The Diagnosis And Management Of Infected Bronchogenic Mediastinal Cysts In Adults, Hazim S. Bukamur, Emad Alkhankan, Haitem Mezughi, Nancy J. Munn, Yousef R. Shweihat

Internal Medicine

Bronchogenic and other duplication cysts are congenital abnormalities that can present at any age including adulthood years. They are usually asymptomatic and discovered incidentally on radiological imaging of the chest. They are commonly treated by surgical resection. Recently, endobronchial ultrasound has been used to assist in diagnosis when radiologic imaging is not definitive. Endobronchial ultrasound has been used rarely to drain infected cysts, a rare complication of the bronchogenic cyst. We present a unique case of an infected large bronchogenic cyst treated with endobronchial ultrasound drainage combined with conservative medical therapy. We also review the scarce available literature describing such …


Small Cell Carcinoma Of Prostate: A Case Report Of A Patient With Concomitant Transitional Cell Cancer Of The Bladder, Waiel Abusnina, Eric Y. Auyoung, Mohammed Megri, Toni H. Pacioles Mar 2018

Small Cell Carcinoma Of Prostate: A Case Report Of A Patient With Concomitant Transitional Cell Cancer Of The Bladder, Waiel Abusnina, Eric Y. Auyoung, Mohammed Megri, Toni H. Pacioles

Internal Medicine

Small cell carcinomas (SCCs) are aggressive neoplasms commonly associated with a pulmonary origin. However, albeit rare, extrapulmonary SCC can occur in a variety of sites with an incidence in North America approximated to be 0.1% to 0.4%. Among these sites, approximately 10% of extrapulmonary SCC cases occur in the prostate and are associated with a poor mortality with a median survival of 10 months. Because of the rarity of the prostatic SCC, there is no formal treatment protocol. In this case report, we present a patient who was diagnosed with SCC in the prostate as primary origin. Adjuvant concurrent chemoradiotherapy …


Restoration Of Completely Transected Common Bile Duct Continuity Using Single Operator Cholangioscopy, Saad Emhmed Ali, Houssam Mardini, Mohsin Salih, Steven J. Krohmer, Wesam M. Frandah Oct 2017

Restoration Of Completely Transected Common Bile Duct Continuity Using Single Operator Cholangioscopy, Saad Emhmed Ali, Houssam Mardini, Mohsin Salih, Steven J. Krohmer, Wesam M. Frandah

Internal Medicine

Common bile duct (CBD) injury, ranging from a partial tear to a complete transection, is a major surgical complication of cholecystectomy with significant morbidity and mortality. Proper management of these complex injuries depends on the type and extent of injury and time of recognition. Identifying and repairing injuries during cholecystectomy can prevent development of complications, but this only occurs in about one-third of cases. We report a novel technique to reconnect a transected CBD with assistance of single-operator cholangioscopy.


Pneumonia Due To A Rare Pathogen: Achromobacter Xylosoxidans, Subspecies Denitrificans, Hesham Awadh, Munthir Mansour, Obadah Aqtash, Yousef Shweihat Aug 2017

Pneumonia Due To A Rare Pathogen: Achromobacter Xylosoxidans, Subspecies Denitrificans, Hesham Awadh, Munthir Mansour, Obadah Aqtash, Yousef Shweihat

Internal Medicine

Achromobacter xylosoxidans, subspecies denitrificans, is a gram-negative rod recently implicated as an emerging cause of infection in both immunosuppressed and immunocompetent populations. Few cases are reported in literature involvingmultiple body systems. Diagnosis depends on cultures of appropriate specimens, and management usually is by administration of appropriate antibiotics(usually agents with antipseudomonal activity).We report a rare case of pneumonia due to infection with this organism, in a patient with preexisting bronchiectasis secondary to chronic aspiration.


Bronchopleural Fistula Resolution With Endobronchial Valve Placement And Liberation From Mechanical Ventilation In Acute Respiratory Distress Syndrome: A Case Series, Haris Kalatoudis, Nikhil Meena, Fuad Zeid, Yousef Shweihat Jul 2017

Bronchopleural Fistula Resolution With Endobronchial Valve Placement And Liberation From Mechanical Ventilation In Acute Respiratory Distress Syndrome: A Case Series, Haris Kalatoudis, Nikhil Meena, Fuad Zeid, Yousef Shweihat

Internal Medicine

Patients who have acute respiratory distress syndrome (ARDS) with persistent air leaks have worse outcomes. Endobronchial valves (EBV) are frequently deployed after pulmonary resection in noncritically ill patients to reduce and eliminate bronchopleural fistulas (BPFs) with persistent air leak (PAL). Information regarding EBV placement in mechanically ventilated patients with ARDS and high volume persistent air leaks is rare and limited to case reports. We describe three cases where EBV placement facilitated endotracheal extubation in patients with severe respiratory failure on prolonged mechanical ventilation with BPFs. In each case, EBV placement led to immediate resolution of PAL. We believe endobronchial valve …


Pembrolizumab Reactivates Pulmonary Granulomatosis, Majdi Al-Dliw, Mohammed Megri, Ibrahim M. Shahoub, Gaurav Sahay, Teresa I. Limjoco, Yousef Shweihat Jul 2017

Pembrolizumab Reactivates Pulmonary Granulomatosis, Majdi Al-Dliw, Mohammed Megri, Ibrahim M. Shahoub, Gaurav Sahay, Teresa I. Limjoco, Yousef Shweihat

Internal Medicine

Sarcoid like reaction is a well-known entity that occurs as a consequence to several malignancies or their therapies. Immunotherapy has gained a lot of interest in the past few years and has recently gained approval as first line therapy in multiple advanced stage malignancies. Pneumonitis has been described as complication of such therapy. Granulomatous inflammation has been only rarely reported subsequent to immunotherapy. We describe a case of granulomatous inflammation reactivation affecting the lungs in a patient previously exposed to Pembrolizumab and have evidence of a distant granulomatous infection. We discuss potential mechanisms of the inflammation and assert the importance …


Mrsa Induced Pulmonary-Renal Syndrome, Mohammed Megri, Majdi Al-Dliw, Yousef Shweihat, Zeid Khitan Jan 2017

Mrsa Induced Pulmonary-Renal Syndrome, Mohammed Megri, Majdi Al-Dliw, Yousef Shweihat, Zeid Khitan

Internal Medicine

We present a rare case of pulmonary-renal syndrome secondary to recurrent MRSA spondylodiscitis. The mechanism of involvement of each organ system is unique. The organs, lung and kidneys, have been affected by different pathologic processes that were induced, we think, by the chronic MRSA infection.


Chronic Kidney Disease And Acute Myocardial Infarction: The Story After 1 Year, Paulette S. Wehner, William A. Nitardy May 2016

Chronic Kidney Disease And Acute Myocardial Infarction: The Story After 1 Year, Paulette S. Wehner, William A. Nitardy

Internal Medicine

When chronic kidney disease (CKD) is part of the clinical history for a patient with acute myocardial infarction, the interventional cardiologist experiences an increased anxiety level. An acute myocardial infarction with renal disease requires more attention to dye load and fluid status, and general opinion exists regarding the negative outcomes of these “sicker” patients.

Mark Navarro and colleagues completed a thorough study from a different angle. We know the interventionalists’ concerns are justified acutely as these CKD patients have a higher level of inpatient complications, but these authors chose to look at the patients 1 year from their event to …


Esophageal Diagnosis Of A Malignant Aspergilloma, Muneer Al Zoby, Nancy Munn,, Yousef Shweihat May 2016

Esophageal Diagnosis Of A Malignant Aspergilloma, Muneer Al Zoby, Nancy Munn,, Yousef Shweihat

Internal Medicine

A 59-year-old male patient developed a new 4 cm × 6 cm cavitary left upper lung lesion over a 2 months period. The patient had a prior history of a surgically resected Stage IA non-small cell lung cancer in the right upper lobe 3 years prior. He was treated for possible infection with radiographic improvement on subsequent imaging. Further imaging after 3 months revealed an oval soft tissue density within the cavity with air crescent sign. Bronchoscopy with transbronchial biopsies showed an acute and chronic granulomatous inflammation. Aspergillus fumigatus was noted on culture and voriconazole was initiated. Subsequent imaging showed …

Dementia Care: Confronting Myths In Clinical Management, Shirley M. Neitch Md, Charles Meadows Md, Eva Patton-Tackett Md, Kevin W. Yingling Md

Internal Medicine

Enormous challenges of this pervasive life-changing condition. Seeking help, often grasping at straws, victims, and their care providers are confronted with misinformation and myths when they search the internet or other sources. When Persons with Dementia (PWD) and their caregivers believe and/or act on false information, proper treatment may be delayed, and ultimately damage can be done. In this paper, we review commonly misunderstood issues encountered in caring for PWD. Our goal is to equip Primary Care Practitioners (PCPs) with accurate information to share with patients and families, to improve the outcomes of PWD to the greatest extent possible.

Recognizing Guttate Psoriasis And Initiating Appropriate Treatment, Lacey Vence Md, Amanda Schmitt, Charles Meadows Md, Todd W. Gress Mph Jul 2015

Recognizing Guttate Psoriasis And Initiating Appropriate Treatment, Lacey Vence Md, Amanda Schmitt, Charles Meadows Md, Todd W. Gress Mph

Internal Medicine

Guttate psoriasis is a less common form of psoriasis. It manifests with numerous small, teardrop shaped, scaly plaques on the trunk and extremities. The etiology includes both environmental and genetic factors. It commonly arises 3-4 weeks following a beta hemolytic streptococcal infection. In some cases, it may be misdiagnosed as an allergy to the antibiotics being used to treat the streptococcal infection. The treatment of guttate psoriasis can vary by severity, but the mainstay treatment includes photo therapy and topical steroids. This case report presents the etiology, clinical findings and current treatment options of guttate psoriasis. It also discusses importance …


Severe Pneumomediastinum Complicating Ebus-Tbna, Yousef Shweihat, James D. Perry Iii, Nancy Munn Jul 2015

Severe Pneumomediastinum Complicating Ebus-Tbna, Yousef Shweihat, James D. Perry Iii, Nancy Munn

Internal Medicine

Pneumomediastinum infrequently complicates diagnostic bronchoscopy. Increased airway or alveolar pressure results in air leaks to the mediastinum through existing or induced defects. Excessive cough, recurrent episodes of increased abdominal pressure, vomiting, or sneezing can all induce spontaneous pneumomediastinum. Less commonly it has been documented with lung or neck infections, esophageal or tracheal tears, and rapid increases in altitude such as during plane flights or scuba diving, with mechanical ventilation, substance abuse, and after bronchoscopy. Pneumomediastinum may be, but is not always, associated with pneumothorax.

Harrison, Stanley Grogg, Antonio Carbayo, Simon Carlo-Torres, Robert Jean Freau, Ana Quintero-Del-Rio, Gisele Bautista, Michael Povey, Christopher Da Costa, Ouzama Nicholson, Bruce L. Innis

Internal Medicine

Background: M-M-RTMII (MMRII; Merck & Co) is currently the only measles-mumps-rubella (MMR) vaccine licensed in the United States. Another licensed vaccine would reinforce MMR supply. This study assessed the immunogenicity of a candidate vaccine (PriorixTM, GlaxoSmithKline Vaccines [MMR-RIT]) when used as a first dose among eligible children in the United States.

Methods: In this exploratory Phase-2, multicenter, observer-blind study, 1220 healthy subjects aged 12–15 months were randomized (3:3:3:3) and received 1 dose of 1 of 3 MMR-RIT lots with differing mumps virus titers (MMR-RIT-1 [4.8 log10]; MMR-RIT-2 [4.1 log10]; MMR-RIT-3 [3.7 log10] CCID50) or MMRII co-administered with hepatitis Avaccine (HAV), …


Is Chest Tube Insertion With Ultrasound Guidance Safe In Patients Using Clopidogrel?, Wissam Abouzgheib, Yousef R. Shweihat, Nikhil Meena, Thaddeus Barrter Nov 2012

Is Chest Tube Insertion With Ultrasound Guidance Safe In Patients Using Clopidogrel?, Wissam Abouzgheib, Yousef R. Shweihat, Nikhil Meena, Thaddeus Barrter

Internal Medicine

Background and objective: Drainage of the pleural space is a common procedure.The safety of chest tube insertion in patients using clopidogrel has not been investigated.

Methods: Ultrasound-guided chest tube insertions performed on 24 patients who were being actively treated with clopidogrel were retrospectively reviewed.

Results: No excessive bleeding occurred in any of these patients.

Conclusions: Given the known effects of clopidogrel on platelet function, these results were interpreted as indicating that clopidogrel therapy is a relative but not an absolute contraindication to chest tube insertion, if an experienced operator places a small-bore tube under ultrasound guidance.
