Pulmonary Alveolar Microlithiasis Diagnosed With Radiography, Ct, And Bone Scintigraphy, Emad Alkankan, Hasan Yamin, Hazim Bukamur, Fadi Alkhankan, Yousef Shweihat, Fuad Zeid

Internal Medicine

Pulmonary alveolar microlithiasis is rare disease characterized by accumulation of calcium phosphate microlithis in the alveoli. The pathogenesis relates to mutation in the gene SLC34A2 (solute carrier family 34 member 2) located on chromosome 4p15.2, which produces a defective sodium-phosphate cotransporter in alveolar epithelial type-2 cells, making these cells unable to clear phosphorus released during recycling of surfactant.

Case Report: Steroid Responsive Mesothelioma-Related Pleural Effusion, Mena Shehata, Fouad Zaid, Peter Ottaviano, Yousef Shweihat, Nancy Munn

Internal Medicine

Malignant pleural mesothelioma (MPM) is an asbestos-related tumor arising in the pleural cavity. Symptoms reflect extension of disease and include shortness of breath and chest pain. Unexplained pleural effusion and pleural pain in patients exposed to asbestos should raise the suspicion of MPM. The most common radiologic presentation is ipsilateral pleural effusion with or without pleural thickening or a mass. Thoracoscopic biopsy remains the most appropriate procedure for definitive diagnosis of mesothelioma. Despite advancement in diagnostic procedures and biomolecular research, this tumor nevertheless has poor prognosis. Mesothelioma remains a diagnostic and therapeutic challenge and is likely to remain one in …

Challenges In The Diagnosis And Management Of Cushing’S Syndrome Due To Ectopic Acth Caused By Pulmonary Carcinoid Tumor In A Patient With Pneumoconiosis., Hazim Bukamur, Chelsey White, Rodhan Khthir, Alysia Browne, Fauzi Najar, Mohammed Al-Ourani

Internal Medicine

Sites with a high prevalence of pneumoconiosis are especially challenging to physicians. The presence of pneumoconiotic nodules on the chest computerized tomography (CT) scans makes it difficult to localize the source of ectopic adrenocorticotropic hormone (ACTH). Because of false-positive results that may occur with the use of 18 fluorodeoxyglucose ( [¹⁸F]FDG) Positron emission tomography CT (PET/CT) scan, alternative imaging modalities are needed. Gallium [⁶⁸Ga]DOTATATE is a positron emitter-labeled somatostatin analog used with PET/CT, which may improve the diagnostic accuracy of localizing ectopic ACTH-secreting carcinoid tumors in patients with pneumoconiosis by reducing false-positive results. We describe a …

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 …

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

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 …

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.

Systemic Air Embolism Associated With Pleural Pigtail Chest Tube Insertion, Emad Alkhankan, Ahmad R. Nusair, Rida S. Mazagri, Mohammed Al-Ourani

Internal Medicine

Pleural pigtail catheter placement is associated with many complications including pneumothorax, hemorrhage, and chest pain. Air embolism is a known but rare complication of pleural pigtail catheter insertion and has a high risk of occurrence with positive pressure ventilation. In this case report, we present a 50-year-old male with bilateral pneumonia who developed a pneumothorax while on mechanical ventilation with continuous positive airway pressure mode .During the placement of the pleural pigtail catheter to correct the pneumothorax, the patient developed a sudden left sided body weakness and became unresponsive. An air embolism was identified in the right main cerebral artery, …

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 …

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.

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.
