Resolution of Primary Lymphedema: A Case Report

Co-Author

Feb 2017

Primary lymphedema is a rare, progressive disease that typically affects the lower extremity.

Beckwith–Wiedemann Syndrome and Primary Lymphedema of the Lower Extremity

Co-Author

Oct 2016

Beckwith–Wiedemann syndrome is the most common genetic overgrowth syndrome. Patients with Beckwith–Wiedemann syndrome may have hemihypertrophy, but their lymphatic vasculature is intact. We present a child with Beckwith–Wiedemann syndrome and lower extremity enlargement thought to be due to hemihypertrophy that was instead diagnosed with primary lymphedema. There are many causes of leg...

Operative Treatment of Lymphedema Using Suction-Assisted Lipectomy

Philadelphia, PA, USA

Surgical management of lymphedema includes removal of affected tissues (excisional procedures), or operations that create new lymphatic connections (physiologic procedures). The purpose of this study was to determine the efficacy of one type of excisional procedure, suction-assisted lipectomy, for extremity lymphedema. Suction-assisted lipectomy is an effective technique to reduce extremity...

An Experimental Study of Particulate Bone Graft for Secondary Inlay Cranioplasty Over Scarred Dura

Lead Author

Combined Lymphedema and Capillary Malformation of the Lower Extremity

Lead author

Feb 2016

Primary lymphedema and capillary malformation are independent vascular malformations that can cause overgrowth of the lower extremity. We report a series of patients who had both types of malformations affecting the same leg. The condition is unique but may be confused with other types of vascular malformation overgrowth conditions (eg, Klippel–Trenaunay and Parkes Weber)...

Endothelial Cells from Capillary Malformations Are Enriched for Somatic GNAQ Mutations

Co-Author

Lymphatic and Other Vascular Malformative/Overgrowth Disorders Are Caused by Somatic Mutations in PIK3CA

Co-Author

Apr 2015

Somatic PIK3CA mutations are the most common cause of isolated LMs and disorders in which LM is a component feature. Five PIK3CA mutations account for most cases. The search for causal mutations requires sampling of affected tissues and techniques that are capable of detecting low-level somatic mosaicism because the abundance of mutant cells in a malformed tissue can be low...

False Negative Cytology in Large Thyroid Nodules

Co-Author

Jan 2015

Controversy exists regarding the accuracy of fine-needle aspiration (FNA) in large thyroid nodules. Recent surgical series have documented false-negative rates ranging from 0.7 to 13 %. We examined the accuracy of benign FNA cytology in patients with thyroid nodules ≥3 cm who underwent surgical resection and identified features characteristic of false-negative results...

Infantile Hemangioma: Treatment Rate During the Proliferating Phase

Co-Author

Sep 2014

Infantile hemangiomas affect 2% to 5% of children and are the most common tumor of infancy. The lesions grow rapidly during the first 9 months; 80% of their size is reached by approximately 5 months. After infancy, infantile hemangiomas shrink, and most have completed involution by 4 years. Infantile hemangiomas typically are small and nonproblematic and are simply observed as they enlarge...

Lymphedema

Lead Author

Aug 2014

Lymphedema is the chronic, progressive swelling of tissue due to inadequate lymphatic function. Over time, protein-rich fluid accumulates in the tissue, causing it to enlarge. Lymphedema is a specific disease and should not be used as a generic term for an enlarged extremity. The diagnosis is made by evaluating the history and physical examination, and can be confirmed with lymphoscintigraphy...

Hypercalcemia in the emergency department: a missed opportunity

Co-Author

Aug 2014

Primary hyperparathyroidism is surgically correctable and frequently presents with mild hypercalcemia. The symptoms of hyperparathyroidism are nonspecific often leading to a delay in diagnosis until patients present with an acute condition. Literature suggests that up to 20 per cent of patients presenting to the emergency department (ED) found to have hypercalcemia are ultimately diagnosed with...

Downregulation of RelA (p65) by Rapamycin Inhibits Murine Adipocyte Differentiation and Reduces Fat Mass of C57BL/6J Mice despite High Fat Diet

Co-Author

London, UK

Rapamycin (RAPA) is a clinical immunosuppressive agent first reported in the literature in 1975 after its discovery in a soil sample from the island of Rapa Nui. Aside from the well-documented effects of RAPA on cell division and immunologic response, the literature reveals it to have negative effects on adipocyte and osteocyte differentiation as well. Understanding of the molecular effects of...

Obesity-induced Upper Extremity Lymphedema

Co-Author

Oct 2013

Obesity increases the risk of upper extremity lymphedema following treatment for breast cancer and can cause lower extremity lymphatic dysfunction in extremely obese individuals. We report the first patient with obesity-induced upper extremity lymphedema. A 62-year-old man with a previous body mass index (BMI) of 105.6, presented with a BMI 60.3 following weight loss. He complained of...

Infantile hemangioma: clinical assessment of the involuting phase and implications for management

Co-author

Sep 2012

Philadelphia, PA, USA

Infantile hemangioma involutes during childhood; the tumor decreases in size and its color fades. Reconstructive procedures are often withheld until the lesion stops improving. The purpose of this study was to determine the age at which involution of infantile hemangioma ends, and factors that influence its regression. Most infantile hemangiomas do not improve significantly after 3.5 years of ...
