Multiple Papillomatosis of Breast and Patient's Choice of Treatment

Papillary lesions of breast represent a range of lesions. Intraductal papilloma and its association with nipple discharge are well known. However, multiple papillomatosis has quite distinct characteristics and decision making can be somewhat challenging. We report a case of multiple papillomatosis in association with ductal carcinoma in situ (DCIS). Patient opted for ipsilateral mastectomy and prophylactic mastectomy of contralateral breast. Her decision of having prophylactic mastectomy was vindicated by presence of incidental DCIS in the contralateral breast. To our knowledge, this is the first reported case of multiple papillomatosis with DCIS of breast, along with incidental synchronous papillomatosis of contralateral breast with DCIS. The case illustrates few distinct features of multiple papillomatosis of breast and exemplifies how a patient's choice is so paramount in decision making process. Patients should be fully informed of the treatment options of the condition, and their wishes should be fully taken into account while making the final decision

Measuring the minimum biofilm eradication concentration for bacterial isolates from diabetic foot infections

Background: Diabetic foot infection (DFI) is considered the most common cause of diabetes-related hospitalization. Diabetic foot ulcers are subjected to bacterial colonization with biofilm forming organisms which are difficult to eradicate. The aim of this study was to identify the spectrum of bacteria associated with DFI and their ability to form biofilm, to evaluate differences in antibiotic susceptibility pattern between planktonic and biofilm phases, and to determine the antibiotics which are active on the organism in the biofilm phase. Methods: The study comprised 50 patients with DFI. A deep swab was collected from each patient and cultured. All isolates were identified and screened for biofilm formation. Biofilm forming isolates were further subjected to minimum biofilm eradication concentration (MBEC) assays to determine resistance to different antimicrobials while in the biofilm phase. Results: Seventy-one isolates were identified, (14.1%) were Gram positive cocci, (83.1%) were Gram negative bacilli, and (2.8%) were Candida species. The most frequently isolated organism was Klebsiella spp. (18/71, 25.4%), followed by Proteus spp. (14/71, 19.7%). The prevalence of biofilm forming isolates was 38%. All the studied isolates showed MBEC higher than the MIC for all tested antimicrobials. Conclusions: The substantial discrepancy between MIC and MBEC results observed in this study emphasizes the lack of reliability of the routine antimicrobial susceptibility testing in case of biofilm formation. Among all tested antimicrobials; cefoperazone/sulbactam, gentamicin, and vancomycin demonstrated activity against bacteria in the biofilm phase

Combining Spreader Grafts with Suture Suspension for Management of Narrow Internal Nasal Valve Angles

Objective:The present study aimed to evaluate the long-term results of combining spreader grafts with lateral suspension techniques for management of narrow internal nasal valves.Methods: This prospective study included 79 patients who underwent surgical interference for dysfunctional nasal valve. The surgical intervention was a combination of two commonly used techniques for management of internal nasal valve dysfunction: spreader graft insertion and lateral suspension of the upper lateral cartilages. The patients were assessed using the nasal obstruction symptom evaluation (NOSE) tool, computed tomography (CT) scans, and endoscopic examinations.Results: All patients reported initial improvement and satisfaction in nasal breathing. Seventy-two patients (91%) reported sustained relief of nasal breathing for at least 3 years postoperatively. The mean NOSE scores decreased from 69.8 to 20.65 postoperatively. The internal nasal valve angle, as measured endoscopically, increased from 7.23° to 13.05° on the right side and from 6.75° to 11.98° on the left side; the increase was statistically significant. The angle, as measured on axial CT scans, increased from 8.11° to 14.15° on the right side and from 6.98° to 12.13° on the left side’ this increase, too, was statistically significant.Conclusion: Combining spreader grafts with lateral suspension sutures provide good, stable, and sustained repair of dysfunctional narrowed internal nasal valves

Evaluation of Turkish oregano (Origanum onites L.) under organic farming system

Spice production is crucial for the world economy. Today, the farming of spices faces significant challenges under climate change, such as heat stress, rising salinity, water stress, low soil nutrients, and increased pests, which lead to reduced yield and quality. The present study was conducted in Egypt on Turkish oregano (Origanum onites L.) plants. The trial was achieved under organic farming conditions. The purpose was to investigate the responses of the plant towards two natural stimulators, chitosan and biofertilizer. The design of the work was a split plot. Main plots were assigned to the foliar spray of chitosan at three concentrations (0, 5, and 10 liters/hectare) and sub-plots to biofertilizer EM (with and without). The collected data comprised plant height, fresh and dry herb weights per plant, fresh and dry herb yields per hectare, essential oil percentage, oil yield per plant and hectare, and GC-MS analysis of oils. The significant maximum growth and yield characteristics were obtained by spraying with chitosan at the highest concentration of 10 liters/hectare combined with soil drenching by biofertilizer EM. The major essential oil component was carvacrol, which is responsible for its pungent flavour. This previous treatment also recorded the maximum carvacrol percent in oil of all cuts. So, this treatment could be used to increase the quantity and quality of the organic product

An intelligent method to analyze the motion in a stream video line using the methods of background subtraction, temporal differencing, and optical flow, methods are proposed. The new method solves the computational time problem by using a reliable technique that is called Fast Pixels Selection. A low cost tracking system is proposed. This tracking system consist of camera, PC, motor and data acquisition card. This system is designed to detect and track any moving target automatically

Stimulation of rhamnolipid biosurfactants production in Pseudomonas aeruginosa AK6U by organosulfur compounds provided as sulfur sources

AbstractA Pseudomonas aeruginosa AK6U strain produced rhamnolipid biosurfactants to variable extents when grown on MgSO4 or organosulfur compounds as sulfur sources and glucose as a carbon source. Organosulfur cultures produced much higher biosurfactants amounts compared to the MgSO4 cultures. The surface tension of the growth medium was reduced from 72mN/m to 54 and 30mN/m in cultures containing MgSO4 and 4,6-dimethyldibenzothiophene (4,6-DM-DBT), respectively. AK6U cultures produced different rhamnolipid congener profiles depending on the provided sulfur source. The dibenzothiophene (DBT) culture produced more diverse and a higher number of rhamnolipid congeners as compared to the DBT-sulfone and MgSO4 cultures. The number of mono-rhamnolipid congeners in the DBT culture was also higher than that detected in the DBT-sulfone and MgSO4 cultures. Di-rhamnolipids dominated the congener profiles in all the analyzed cultures. The sulfur source can have a profound impact on the quality and quantity of the produced biosurfactants

Natural Attenuation Potential of Polychlorinated Biphenyl-Polluted Marine Sediments

The marine environment in Kuwait is polluted with various hazardous chemicals of industrial origin. These include petroleum hydrocarbons, halogenated compounds and heavy metals. Bioremediation with dedicated microorganisms can be effectively applied for reclamation of the polluted marine sediments. However, information on the autochthonous microbes and their ecophysiology is largely lacking. We analyzed sediments from Shuwaikh harbor to detect polychlorinated biphenyls (PCBs) and total petroleum hydrocarbons (TPHs). Then we adopted both culture-dependent and culture-independent (PCR-DGGE) approaches to identify bacterial inhabitants of the polluted marine sediments from Shuwaikh harbor. The chemical analysis revealed spatial variation among the sampling stations in terms of total amount of PCBs, TPHs and the PCB congener fingerprints. Moreover, in all analyzed sediments, the medium-chlorine PCB congeners were more abundant than the low-chlorine and high-chlorine counterparts. PCR-DGGE showed the presence of members of the Proteobacteria, Spirochaetes, Firmicutes and Bacteroidetes in the analyzed sediments. However, Chloroflexi-related bacteria dominated the detected bacterial community. We also enriched a biphenyl-utilizing mixed culture using the W2 station sediment as an inoculum in chemically defined medium using biphenyl as a sole carbon and energy source. The enriched mixed culture consisted mainly of the Firmicute Paenibacillus spp. Sequences of genes encoding putative aromatic ring-hydroxylating dioxygenases were detected in sediments from most sampling stations and the enriched mixed culture. The results suggest the potential of bioremediation as a means for natural attenuation of Shuwaikh harbor sediments polluted with PCBs and TPHs

New three-dimensional poly(decanediol-co-tricarballylate) elastomeric fibrous mesh fabricated by photoreactive electrospinning for cardiac tissue engineering applications

Reactive electrospinning is capable of efficiently producing in situ crosslinked scaffolds resembling the natural extracellular matrix with tunable characteristics. In this study, we aimed to synthesize, characterize, and investigate the in vitro cytocompatibility of electrospun fibers of acrylated poly(1,10-decanediol-co-tricarballylate) copolymer prepared utilizing the photoreactive electrospinning process with ultraviolet radiation for crosslinking, to be used for cardiac tissue engineering applications. Chemical, thermal, and morphological characterization confirmed the successful synthesis of the polymer used for production of the electrospun fibrous scaffolds with more than 70% porosity. Mechanical testing confirmed the elastomeric nature of the fibers required to withstand cardiac contraction and relaxation. The cell viability assay showed no significant cytotoxicity of the fibers on cultured cardiomyoblasts and the cell-scaffolds interaction study showed a significant increase in cell attachment and growth on the electrospun fibers compared to the reference. This data suggests that the newly synthesized fibrous scaffold constitutes a promising candidate for cardiac tissue engineering applications
