AIMS: The diagnosis of cutaneous gamma delta T-cell lymphoma (GDTCL) requires the identification of γδ chains of the T-cell receptor (TCR). Using a new mAb to TCRδ, we evaluated TCRδ expression in formalin fixed paraffin embedded (FFPE) skin tissue from TCRγ-positive cutaneous T-cell lymphoma (CTCL) and assessed TCRδ expression within a spectrum of other cutaneous lymphoproliferative disorders (CLPD). METHODS AND RESULTS: 12 cases (10 patients) with TCRγ-positive CTCL and 132 additional CLPD cases (127 patients) were examined including mycosis fungoides (MF, n=60), cutaneous GDTCL (n=15), subcutaneous panniculitis-like T-cell lymphomas (SPTCL, n=11), and CD30+ lymphoproliferative disorders (CD30+LPDs, n=24)...

While clinical outcomes of minimally invasive pancreatic resection (MIPR) compared to open surgery are well examined, only few studies focus on its associated cost. The aim of this study is to evaluate cost analyses comparing MIPR to open pancreatic resection (OPR). A systematic review of the literature using PubMed of all published studies between 2000 and 2017 was performed. Studies reporting on cost of laparoscopic distal pancreatectomy (LDP) and laparoscopic pancreatoduodenectomy (LPD) compared to open surgery were identified...

BACKGROUND: A lateral patellar dislocation (LPD) is the most common traumatic knee injury with hemarthrosis in children. The redislocation rate is high. Varying operative and nonoperative treatments have been advocated with no consensus on the best treatment. PURPOSE: (1) To evaluate if arthroscopic-assisted repair of the medial patellofemoral ligament (MPFL) in patients with an acute first-time traumatic LPD would reduce the recurrence rate and offer better objective/subjective knee function compared with a knee brace without repair...

Extranodal NK/T cell lymphoma, nasal type (ENKL) developed in a patient with intestinal Epstein-Barr virus (EBV)-positive T/NK-cell lymphoproliferative disorder (LPD). The patient was a 46-year-old Chinese man who complained of diarrhea and abdominal pain without immune-deficiency. Endoscopy demonstrated ileum ulcers like Crohn's disease, without histological granulomas. His symptoms continued waxing and waning for 3 years until he developed overt lymphoma (ENKL) in the nasal cavity. The ileum lesions exacerbated into a large deep ulcer, and the biopsy specimens from the ileum, including the one 3 years ago, showed infiltration of small lymphocytes containing many EBV-positive T/NK cells without atypia...

Epstein-Barr virus (EBV) is associated with several life-threatening diseases, such as lymphoproliferative disease (LPD), particularly in immunocompromised hosts. Some categories of primary immunodeficiency diseases (PIDs) including X-linked lymphoproliferative syndrome (XLP), are characterized by susceptibility and vulnerability to EBV infection. The number of genetically defined PIDs is rapidly increasing, and clinical genetic testing plays an important role in establishing a definitive diagnosis. Whole-exome sequencing is performed for diagnosing rare genetic diseases, but is both expensive and time-consuming...

BACKGROUND: Minimally invasive pancreaticoduodenectomy (MIPD) was introduced in the attempt to improve the outcomes of the open approach. Laparoscopic pancreaticoduodenectomy (LPD) was first reported by Gagner and Pomp (Surg Endosc 8:408-410, 1994). Unfortunately, due to its complexity and technical demand, LPD never reached widespread popularity. Since it was first performed by P. C. Giulianotti in 2001, Robotic PD (RPD) has been gaining ground among surgeons. MIPD is included as a surgical option in the latest NCCN Guidelines...

Carcinogenesis is frequently linked to genetic background, however, exposure to environmental risk factors has gained attention as the etiologic agent for several types of cancer, including prostate. The intrauterine microenvironment has been described as a preponderant factor for offspring health; and maternal exposure to insult has been linked to chronic disease in older offspring. Using a model of maternal exposure to low protein diet (LPD; 6% protein), we demonstrated that impairment of offspring rat prostatic growth on postnatal day (PND) 21 was associated with prostate carcinogenesis in older offspring (PND 540)...

In recent years, laparoscopic procedures have developed rapidly, and the reports of laparoscopic pancreatic resection including laparoscopic pancreaticoduodenectomy (LPD) have increased in number. Although LPD is a complex procedure with high mortality, the training system for LPD remains unestablished. Ensuring patient safety is extremely important, even in challenging surgeries such a LPD. At present, several tools have been developed for surgical education to ensure patient safety preoperatively, such as video learning, virtual reality simulators, and cadaver training...

Rabbit antithymocyte globulin (ATG) is an effective immunosuppressive therapy for patients with aplastic anemia (AA). However, Epstein-Barr virus-associated lymphoproliferative disorder (EBV-LPD) is a rare but serious complication of the therapy. An 81-year-old man was diagnosed with severe AA on the occasion of melena. Because cyclosporine monotherapy did not improve his condition, rabbit ATG was additionally administered. Thirty-one days after the administration of rabbit ATG, the patient presented with fever and general malaise...

BACKGROUND: The impact of the low-protein diet on nutrition in CKD diabetics is uncertain. METHODS: The metabolic and nutritional effects of a low-protein (0.5-0.6 g/kg/d), normal-high energy (30-35 kcal/kg/d) diet supplemented with ketoacids (LPD-KA) were prospectively evaluated in CKD patients with (DM) and without (non-DM) diabetes mellitus. RESULTS: 197 patients on CKD stages 3-5 were enrolled. DM (n = 81) and non-DM (n = 116) were comparable for gender (Male 58 vs 55%), age (66 ± 9 vs 63 ± 18 years), renal function (eGFR 23 ± 13 vs 24 ± 13 mL/min)...

PURPOSE OF REVIEW: Lateral patellar dislocation (LPD) is one of the most common injuries of the knee, especially in a young patient. It is multifactorial with several underlying risk factors. The purpose of this review is to present the most recent data concerning risk factors and their predictive value to estimate recurrent LPD risk. RECENT FINDINGS: Several demographic risk factors (age, skeletal immaturity, sex, bilaterality), mechanism of injury, and anatomic risk factors (trochlear dysplasia, patella alta, excessive tibial tubercle lateralization, increased patellar tilt) have been recognized...

Immunosuppressive medications, frequently used to treat inflammatory bowel disease, have been linked to the development of Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (LPD). We describe a case of an EBV-positive mucocutaneous ulcer involving the palate in an elderly woman with inactive Crohn's disease. This patient had been on high-dose azathioprine for a decade. Following diagnosis of her LPD and discontinuation of azathioprine, her oral ulcers resolved completely.

BACKGROUND: Laparoscopic pancreatoduodenectomy is a highly challenging procedure. The aim of this study was to analyse post-operative morbidity and mortality as well as long term overall survival in patients undergoing hybrid LPD, as compared to open pancreaticoduodenecomy (OPD) in a single surgeon series. METHODS: Patients undergoing pancreatoduodenectomy (PD) in the period from 2000 to 2015 were identified from a prospectively maintained database. All LPD procedures were performed by one specialised pancreatic surgeon (TK)...

Cutaneous CD30+ T-cell lymphoproliferative disorders (CD30+ LPD) are the second most common form of cutaneous T-cell lymphoma. CD30+ LPD include lymphomatoid papulosis, primary cutaneous anaplastic large-cell lymphoma, and borderline lesions. Despite expression of CD30 by the neoplastic cells as the hallmark of these disorders, they differ in their clinical presentation and histological features as well as the course, the prognosis, and consecutively in the treatment. Diagnosis of CD30+ LPD and distinction from the broad spectrum of differential diagnoses essentially depends on clinicopathologic correlation as well as the results of staging examinations...

Recently, methotrexate-associated lymphoproliferative disorders (MTX-LPDs) in rheumatoid arthritis (RA) have been found to commonly occur in association with iatrogenic immunodeficiency. Several factors have been reported to be related to the prognosis. We herein investigate the efficacy of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in predicting the prognosis of MTX-LPD. We performed a retrospective analysis of the clinical features, characteristics, and outcomes of 18 patients with MTX-LPDs who were treated from 2004 to 2015...

Peripheral vascular disease (PVD) is a prevalent vascular disease that affect a large number of patients. The establishment of optimal treatments to mitigate the intimal hyperplasia (IH)-induced restenosis would help relieve the health burden of the PVD. Ribonucleotide reductase M2 (RRM2) is critical to cellular migration and proliferation. We have previously demonstrated that suppression of RRM2 expression could substantially inhibit hepatocellular carcinoma cell proliferation and migration. We hereby developed RRM2 small interfering RNA (siRNA)-loaded cell penetrating peptides-conjugated liposome-polycation-DNA complex (LPD) (RRM2-CLPD), aiming to inhibit the migration and proliferation of vascular smooth muscle cells (VSMCs) crucial for IH...

A low-protein diet (LPD) can be expected to retard renal function decline in advanced stages of chronic kidney disease (CKD), including diabetic kidney disease (DKD), and is recommended in a clinical setting. Regarding the molecular mechanisms of an LPD against DKD, previous animal studies have shown that an LPD exerts reno-protection through mainly the improvement of glomerular hyperfiltration/hypertension due to the reduction of intraglomerular pressure. On the other hand, we have demonstrated that an LPD, particularly a very-LPD (VLPD), improved tubulo-interstitial damage, inflammation and fibrosis, through the restoration of autophagy via the reduction of a mammalian target of rapamycin complex 1 (mTORC1) activity in type 2 diabetes and obesity animal models...
