Pancreatic islet transplantation has become an established approach to β-cell replacement therapy for the treatment of insulin deficient diabetes. Recent progress in techniques for islet isolation, islet culture, and peri-transplant management of the islet transplant recipient have resulted in substantial improvements in metabolic and safety outcomes for patients. For patients requiring total or sub-total pancreatectomy for benign disease of the pancreas, isolation of islets from the diseased pancreas with intrahepatic transplantation of autologous islets can prevent or ameliorate post-surgical diabetes, and for patients previously experiencing painful recurrent acute or chronic pancreatitis, quality-of-life is substantially improved.

Ga-prostate-specific membrane antigen (PSMA) PET/CT scan for primary staging discovered increased Ga-PSMA uptake in a known anal fistula in a recently diagnosed high-risk prostate cancer patient. The patient had an ongoing history of surgical revisions of complex fistulas in the perianal region, contributing to active inflammation and infection. Recently, reports have demonstrated increased Ga-PSMA uptake in different benign inflammatory conditions. Read More

Masseter hypertrophy is a characteristic condition resulting from an increase in the size of the muscle mass. At times, it produces significant facial asymmetry and is an important finding in the differential diagnosis of similar located entities. A proper diagnosis of this condition would avoid more aggressive and unwarranted therapy by an inexperienced clinician who may mistake it for a more serious pathologic condition. Read More

No consensus guidelines exist on the use of optical coherence tomography (OCT) for diagnosis of cutaneous melanoma. The objectives of this review are to provide a descriptive review of the literature on characteristics of cutaneous melanomas seen on high-definition OCT (HD-OCT), speckle variance OCT (SV-OCT), and conventional OCT and to compare their diagnostic ability with that of histopathology. A review of PubMed and Google Scholar identified all available literature on OCT in melanoma skin cancer that included all in vivo and ex vivo studies on human or human tissues and excluded all studies on non-human subjects or animal studies.

Gastric cancers (GC) after eradication are difficult to diagnose even by magnifying narrow-band imaging (NBI) or blue laser imaging (BLI) endoscopy. Little is known with regard to non-magnifying (NM)-NBI/BLI for early GC so we examined the efficacy of NM-NBI/BLI for early GC diagnosis. We retrospectively analyzed the images of 29 small (≤ 1 cm) intramucosal GC that had been treated with endoscopic submucosal dissection and 137 benign depressed lesions (BDLs). Read More

Fibrous dysplasia is a benign fibro-osseous disease of the bone, which is most commonly associated with congenital mutations in cAMP regulating protein Gsα coded by gene. Often it is seen involving the craniofacial skeleton and can range from an asymptomatic monostotic form to polyostotic variant involving almost all the bones of the skull, thereby leading to functional and esthetic problems. This requires a continuous monitoring of the involved region throughout the life of the patient, even after the surgical interventions. Read More

Peripheral nerve sheath tumors (PNSTs) account for ~ 5% of soft tissue neoplasms and are responsible for a wide spectrum of morbidities ranging from localized neuropathy to fulminant metastatic spread and death. MR imaging represents the gold standard for identification of these neoplasms, however, current anatomic MR imaging markers do not reliably detect or differentiate benign and malignant lesions, and therefore, biopsy or excision is required for definitive diagnosis. Diffusion-weighted MR imaging (DWI) serves as a useful tool in the evaluation and management of PNSTs by providing functional information regarding the degree of diffusion, while diffusion tensor imaging (DTI) aids in determining the directional information of predominant diffusion and has been shown to be particularly useful for pre-operative planning of these tumors by delineating healthy and pathologic fascicles.
