Local prolonged release of antibiotic for prevention of sternal wound infections postcardiac surgery-A novel technology.

Introduction: Sternal wound infection (SWI) is a devastating postcardiac surgical complication. D-PLEX (D-PLEX) is a localized prolonged release compound applied as a prophylactic at the completion of surgery to prevent SWI. The D-PLEX technology platform is built as a matrix of alternating layers of polymers and lipids, entrapping an antibiotic (doxycycline).

D-PLEX500: a local biodegradable prolonged release doxycycline-formulated bone graft for the treatment for peri-implantitis. A randomized controlled clinical study.

Objectives: In the present pilot, multicenter, randomized, single-blinded, controlled study, surgical treatment with or without the administration of D-PLEX500 (a biodegradable prolonged release local doxycycline formulated with β-tricalcium phosphate bone graft) was accessed for the treatment of peri-implantitis.

Method And Materials: Subjects undergoing surgical treatment for intrabony peri-implantitis defects after flap elevation were randomly assigned, to adjunct D-PLEX500 placement group or to control group. Clinical and radiographic parameters were measured at 6 and 12 months.

A doxycycline-loaded polymer-lipid encapsulation matrix coating for the prevention of implant-related osteomyelitis due to doxycycline-resistant methicillin-resistant Staphylococcus aureus.

Implant-associated bone infections caused by antibiotic-resistant pathogens pose significant clinical challenges to treating physicians. Prophylactic strategies that act against resistant organisms, such as methicillin-resistant Staphylococcus aureus (MRSA), are urgently required. In the present study, we investigated the efficacy of a biodegradable Polymer-Lipid Encapsulation MatriX (PLEX) loaded with the antibiotic doxycycline as a local prophylactic strategy against implant-associated osteomyelitis.

Computerized cell-scanning system for evaluating human spermatogenesis in non-obstructive azoospermic patients.

There may be incompatibility between testicular histopathological evaluation and testicular sperm extraction (TESE) outcome. Assessment for sperm presence and different pathological disturbances of non-obstructive azoospermia (NOA) remains challenging. An assay for maximal sampling and accurate identification of testicular cells from NOA patients undergoing TESE and autopsied fertile controls was developed.

Acquisition of a Ph chromosome with minor BCR/ABL fusion in treatment-related myelodysplastic syndrome with chromosome 7 abnormalities in a patient treated for Hodgkin disease.

The patient reported in this study originally had Hodgkin disease that was treated heavily with multiple courses of combined chemotherapy and radiotherapy. Secondary myelodysplastic syndrome (MDS) with a complex karyotype with monosomy 7, deletion 7q31, and double deletion 7q31 developed 8 years later. During the course of the disease, conventional cytogenetics and interphase FISH (I-FISH) analysis detected a Ph chromosome and BCR/ABL fusion with mBCR rearrangement.

Determination of chromosome 13 status in bone marrow cells of patients with multiple myeloma using combined morphologic and fluorescence in situ hybridization analysis.

Deletion of chromosome 13q is believed to be an adverse prognostic marker in patients with multiple myeloma (MM). Interphase fluorescence in situ hybridization (I-FISH) is the method of choice for detection of chromosome 13q deletion (del13q). However, I-FISH has high false-positive rates attributed to a low percentage of plasma cells (PC), which are responsible for MM, in bone marrow (BM) samples from MM patients.

Combined analysis of morphology and fluorescence in situ hybridization in follow-up of minimal residual disease in a child with Philadelphia-positive acute lymphoblastic leukemia.

The past decade has brought new technologies to the study of minimal residual disease (MRD) in leukemia. Each of them has limitations and is far from being accurate. Recently, a new multiparametric cell scanning system (Duet) was introduced to the field of MRD detection.
