BACKGROUND: In an autologous hematopoietic cell transplantation (AHCT) setting, routine cytomegalovirus (CMV) surveillance is not indicated except in high-risk situations. On the other hand, some studies reported increased CMV reactivation in AHCT setting as a result of incorporation of novel agents into treatment algorithms, such as bortezomib and rituximab. We retrospectively analyzed CMV reactivation and infection rates in patients with no high-risk features, who were treated with AHCT...

BACKGROUND AND AIMS: Patients with primary biliary cholangitis (PBC) frequently suffer from extrahepatic autoimmune conditions, of which autoimmune thyroid disease (AITD) is one of the most common. Previous studies identified several genetic variants increasing the odds of developing AITD. Here we investigate whether AITD-associated polymorphisms might also play a role in the development and clinical course of PBC and PBC associated with AITD (PBC-AITD). METHODS: To this end, we prospectively recruited 230 patients with PBC and 421 healthy controls...

The metacarpal-like hand is a severe hand injury, never addressed before. It describes a hand that lost a significant degree of prehension through a wide array of amputations, involving all digits proximal to the functional length except in one finger or in two digits, including the thumb.Thumb condition can be used to differentiate between two types.In type I, the thumb is intact or amputated at/or distal to the interphalangeal joint (functional length); and therefore, the reconstruction is focused on fingers mainly...

The author summarizes briefly the history of hand allograft transplantation, the basics of the operative technics, and the medicinal treatment of the immunosuppression. He establishes that this operation requires complicated team-work: many specialists must be united in the interest of the successful final outcome. The biggest problem is not the technical challenge of the complicated operation, but the ineffectiveness of immunosuppression, its complications; even though significant development has happened in this field and experimental results are also encouraging...

Hypoxia is a common cause of kidney injury and a major issue in kidney transplantation. Mitogen-activated protein kinases (MAPKs) are involved in the cellular response to hypoxia, but the precise roles of MAPKs in renal cell reactions to hypoxic stress are not well known yet. This work was conducted to investigate the regulation of extracellular signal-regulated kinase-1 and -2 (ERK1/2) and p38 and their signaling-relevant molecules in kidney epithelial cells exposed to prolonged hypoxia. Rat kidney epithelial cells Normal Rat Kidney (NRK)-52E were exposed to hypoxic conditions (1% O2) for 24 to 72 h...

POEMS syndrome is a rare, chronic and disabling condition. The causes of this condition remain unknown; however, chronic overproduction of proinflammatory cytokines appears to be a major contributor. Early diagnosis is essential to start treatment before the clinical state of the patient becomes compromised. A complete evaluation of the disease at its onset is critical to the treatment decision. In localized disease, curative doses of radiation (50 Gy) is the recommended therapy. On the other hand, patients with disseminated disease should be given systemic therapy...

BACKGROUND AND OBJECTIVE: Sex chromosome loss (SCL) can occur in older men as a physiological phenomenon or as an acquired abnormality in leukemia. Loss of chromosome Y and loss of chromosome X are acquired disorders that are mainly observed in patients over 80 years as well as in myeloid and lymphoid malignancies. In this review, we examine the cytogenetic and molecular changes of sex chromosomes in leukemia. METHODS: Relevant English language literature were searched and retrieved from PubMed search engine (1990-2016)...

Timed sequential therapy (TST) aims to improve outcomes in acute myelogenous leukemia (AML) by harnessing drug-induced cell cycle kinetics of AML, where a second drug is timed to coincide with peak leukemia proliferation induced by the first drugs. We analyzed outcomes in 301 newly diagnosed AML patients treated from 2004-2013 with cytarabine, anthracycline, and etoposide TST induction. Median age was 52 (range 20-74) and complete remission rate 68%. With median follow-up 5.8 years, 5-year DFS and overall survival (OS) were 37% (95% CI 31-45%) and 32% (95% CI 27-38%), respectively...

The advent of highly conformal radiation therapy (RT) has defined a new role for RT in the treatment of both primary and metastatic liver cancer. Despite major advances in how RT is delivered, radiation-induced liver disease (RILD) remains a concern. Classic RILD, characterized by anicteric ascites and hepatomegaly, is unlikely to occur if treating to doses of ≤30Gy in 2Gy per fraction in patients with baseline Child-Pugh A liver function. On the other hand, nonclassic RILD is a spectrum of liver toxicity, including a general decline in liver function and elevation of liver enzymes...

Toe-to-finger transplantation is intimately related to the development of microsurgical free tissue transplantation, which is one of the most important advances in the history of reconstructive surgery. It is also generally acknowledged that a mangled hand with massive tissue loss and amputation of multiple digits presents a challenge for plastic and reconstructive surgeons. In this retrospective study we reviewed 11 cases of primary one-stage post-traumatic reconstruction of complex fingerless hands using a combination of toe-to-finger and free tissue transplantation performed in Shanghai Jiao Tong University affiliated Sixth People's Hospital and Shanghai Jiao Tong University School of Medicine affiliated Ninth People's Hospital from January 2001 to November 2014...

Sinusoidal obstruction syndrome (SOS) is a life-threatening complication generally occurring after hematopoietic stem cell transplantation. SOS after standard dose chemotherapy in malignancies is rare. Between the year 1995 and 2016, 414 patients were diagnosed with acute lymphoblastic leukemia and 113 patients were diagnosed with Wilms tumor in our institution. Among these patients, 4 patients with acute lymphoblastic leukemia (0.96%) and 2 patients with Wilms tumor (1.7%) developed SOS during treatment. SOS behaves like a local disseminated intravascular coagulation...

Clinical heart failure prevention and contemporary therapy often involve breaking the vicious cycle of global haemodynamic consequences of myocardial decay. The lack of effective regenerative therapies results in a primary focus on preventing further deterioration of cardiac performance. The cellular transplantation hypothesis has been evaluated in many different preclinical models and a handful of important clinical trials. The primary expectation that cellular transplants will be embedded into failing myocardium and fuse with existing functioning cells appears unlikely...

BACKGROUND: Treprostinil is a prostacyclin analog used to treat portopulmonary hypertension (PPHTN) and is one of several drugs shown to increase survival, but results in platelet dysfunction. Little is known about the management of patients on treprostinil who present with an acute subdural hematoma (aSDH). We describe such a case and offer our recommendations on management based on our experience and review of the literature. CASE DESCRIPTION: A 63-year-old, right-handed female with a history of PPHTN presented with severe headache and was found to have a large left aSDH with midline shift on imaging...

Lung transplantation (LUTX) became a worldwide accepted standard therapy for certain well-defined chronic end-stage lung diseases. Until recently, patients on mechanical ventilation or extracorporeal life support techniques were hardly eligible for LUTX because of the inferior short-term results. However, a paradigm shift has occurred, and now these techniques represent bridging options to LUTX for listed patients. In the current practice, transplantation from the intensive care unit (ICU) is not extraordinary in patients on the waiting list...

Claw finger is sequelae of fingers without intrinsic function. Claw toe deformity is common after toe transfers as simultaneous intrinsic reconstruction has yet to be reported in the literature. We present our experience of simultaneous tendon transfers during the second toe transplantation. Seven 2nd toe transfers were performed in 5 metacarpal-like and metacarpal hands. The Stiles-Bunnell tendon transfer was incorporated into toe transfers. Toe lumbrical tendons were repaired to the Flexor Digitorum Sublimis of the same recipient digit...

Solid organ transplant (SOT) recipients are especially at risk of developing infections by multidrug resistant (MDR) Gram-negative bacilli (GNB), as they are frequently exposed to antibiotics and the healthcare setting, and are regulary subject to invasive procedures. Nevertheless, no recommendations concerning prevention and treatment are available. A panel of experts revised the available evidence; this document summarizes their recommendations: (1) it is important to characterize the isolate's phenotypic and genotypic resistance profile; (2) overall, donor colonization should not constitute a contraindication to transplantation, although active infected kidney and lung grafts should be avoided; (3) recipient colonization is associated with an increased risk of infection, but is not a contraindication to transplantation; (4) different surgical prophylaxis regimens are not recommended for patients colonized with carbapenem-resistant GNB; (5) timely detection of carriers, contact isolation precautions, hand hygiene compliance and antibiotic control policies are important preventive measures; (6) there is not sufficient data to recommend intestinal decolonization; (7) colonized lung transplant recipients could benefit from prophylactic inhaled antibiotics, specially for Pseudomonas aeruginosa; (8) colonized SOT recipients should receive an empirical treatment which includes active antibiotics, and directed therapy should be adjusted according to susceptibility study results and the severity of the infection...

BACKGROUND: Actinic keratoses (AKs) in solid organ transplant recipients (OTRs) are difficult-to-treat pre-malignancies and comparison of topical therapies is therefore warranted. OBJECTIVES: In an intra-individual study to compare efficacy and safety of field treatment with methyl aminolevulinate photodynamic therapy (MAL-PDT) and imiquimod (IMIQ) for AKs in OTRs. MATERIALS AND METHODS: OTRs (n=35) with 572 AKs (grade I-III) in two similar areas in the face, scalp, dorsal hands or forearms were included...
