Environmental monitoring and control strategy of urban mosquito Culicidae (Diptera: Culicidae) populations in Wrocław

Among dipterans of medical and veterinary importance, the mosquitoes (Culicidae) play the most important role both as vectors and nuisance insects. Mass occurrence of floodwater mosquito species in the flooded area in Wroc?aw district (Lower Silesia, Poland) in 1997 has enhanced the already existed problem of mosquito control. A successful model of control strategy for the city based on the currently recommended integrated methodologies with special emphasis on preventive treatment of aquatic larvae with microbial insecticides has been conducted. Bacillus thuringiensis israelensis-based formulations replaced chemicals to control Culex pipiens and Culiseta annulata--two dominant species out of eight noticed during field study in Wroc?aw area in the years 1998-2000. Use of Bti larvicide or other biocontrol agent, conserving biodiversity, requires collecting entomological data, mapping and treating all breeding sources as well as the designing appropriate strategies every year.     

Physiotherapeutic assessment and management of chronic pelvic pain syndrome: A case report

Introduction:Chronic pelvic pain syndrome is difficult for the diagnosis and therapy and that means the patient attending the physician or physiotherapist may present various symptoms. There are no guidelines concern physiotherapy diagnosis and treatment of chronic pelvic pain syndrome. This study presents the physiotherapeutic assessment and management in men with pelvic pain symptoms.Patient concerns:Forty-six-year-old man attended the physiotherapy consulting room due to symptoms of pain in the perineum, lower abdomen, urethra, and scrotum for a year. Earlier, the patient had consulted a urologist who made a diagnosis of cystitis and prescribed medications that did not get results.Diagnosis:Ultrasound imaging and manual inspection (per rectum) of the pelvic floor was conducted by physiotherapist. Also, the abdominal and lower extremities muscles were assessed. Patient reported pain symptoms during examination of the musculus ischiocavernosus, puboanalis, pubococcygeus, iliococcygeus, coccygeus, and canalis pudentalis seu Alcocki.Interventions:The patient was given physiotherapeutic interventions consisting in the manual therapy of the lumbopelvic hip complex and the manual therapy per rectum.Outcomes:During 10th session of the physiotherapeutic treatment, patient reported improvement in pain symptoms. A month later, patient reported total alleviation of the pain symptoms during control visit.Conclusion:Therapy of chronic pelvic pain syndrome is a process that involves application of different therapies and different approaches. Functional and structural assessment and also therapy conducted by physiotherapist is becoming an integral part of urology and represents 1 possible conservative treatment form.

Favorable four‐yr outcome after renal transplantation in a patient with complement factor H antibody and CFHR1/CFHR3 gene mutation‐associated HUS

aHUS is a clinical challenge for successful renal transplantation. Case report: A 14‐yr‐old girl lost her kidneys at the age of 7, due to CFH antibodies and CFH‐related protein (CFHR1/CFHR3) homozygous deletion‐associated aHUS. CFH, CFI, and MCP gene mutations were excluded. The patient was a candidate for renal transplantation despite persistent presence of CFH antibodies (up to 539 AU/mL). Treatment with MMF, IVIG, and repeated PF (n = 8) was introduced while being placed on urgent waiting list. Three years after aHUS onset, the patient underwent the deceased donor renal transplantation “under cover” of PF, as PF was performed directly prior to surgery and, then, PFs were repeated up to overall 14 sessions. Quadruple immunosuppression (basiliximab + tacrolimus + MMF + prednisolone) was used. Moderate symptoms of aHUS (hemolysis, low platelets, and low C3) were present within first seven days post‐transplant and then normalized with PF therapy. The patient remained stable during four yr of further follow‐up after transplantation. Conclusion: Specific pre‐ and post‐transplant management allowed successful renal transplantation in a CFH antibody‐positive patient.     

Mid-infrared spectroscopy and microscopy of subcellular structures in eukaryotic cells with atomic force microscopy – infrared spectroscopy

Atomic force microscopy – infrared (AFM-IR) spectroscopy allows spectroscopic studies in the mid-infrared (mid-IR) spectral region with a spatial resolution better than is allowed by the diffraction limit. We show that the high spatial resolution can be used to perform spectroscopic and imaging studies at the subcellular level in fixed eukaryotic cells. We collect AFM-IR images of subcellular structures that include lipid droplets, vesicles and cytoskeletal filaments, by relying on the intrinsic contrast from IR light absorption. We also obtain AFM-IR absorption spectra of individual subcellular structures. Most spectra show features that are recognizable in the IR absorption spectra of cells and tissue obtained with FTIR technology, including absorption bands characteristic of phospholipids and polypeptides. The quality of the spectra and of the images opens the way to structure and composition studies at the subcellular level using mid-IR absorption spectroscopy.

Differences in photoinduced optical transients in perovskite absorbers for solar cells

Methylammonium lead iodide films and powdered crystals were studied by time-resolved absorption and emission spectroscopy on the time scales from femtoseconds to nanoseconds. Strikingly different transient absorption signals were observed, changing from strong long-wavelength band-edge bleach to weak signatures of band-shift, which depended on the absorber form (films or polycrystals) and preparation method (stoichiometric or non-stoichiometric). The observed differences were correlated with the variation in absorption and emission spectra, changes in photo-induced carrier lifetimes and solar cell efficiency. These differences also pointed out that similar perovskite absorbers can provide significantly different transient responses and emphasize that special care must be taken when interpolating the obtained findings to the processes occurring in the most efficient devices.

Striking differences in transient absorption signal are observed for perovskite absorbers prepared with different methods.     

Superb Micro-vascular Imaging (SMI): a Doppler ultrasound technique with potential to identify,classify, and follow up endoleaks in patients after Endovascular Aneurysm Repair (EVAR)

Purpose

The aim of the study was to assess the effectiveness of Superb Micro-vascular Imaging (SMI) as an alternative to Contrast-Enhanced Ultrasound (CEUS) and Computed Tomography Angiography (CTA) for endoleak detection and classification in patients followed up after endovascular abdominal aortic aneurysm repair (EVAR).

Materials and methods

From May 2015 to January 2017, 30 patients underwent post-EVAR follow-up with Color Doppler Ultrasound (CDUS), CEUS, SMI, and CTA examinations. Aneurysmal sac diameter and graft patency were evaluated; endoleaks were identified and classified. Sensitivity, specificity, and accuracy values were calculated for each of the four diagnostic methods of endoleak detection. A percentage of agreement and Cohen’s Kappa coefficient were calculated for comparison of methods in terms of endoleak identification.

Results

CTA revealed fifteen endoleaks (50%): three type Ia, nine type II, and three type III. The sensitivity of CDUS, CEUS, and SMI relative to CTA was 27%, 100%, and 100%, respectively. Specificity was 93%, 93%, and 93%, respectively. Accuracy was 60%, 97%, and 97%, respectively. There were no differences between SMI and CEUS in terms of sensitivity, specificity, or accuracy (100%, 93%, and 97%). We do not observe statistically significant differences between CTA, CEUS, and SMI concerning endoleak identification ability. The weakest method in endoleak identification was CDUS.

Conclusions

The analysis showed that SMI is effective, repeatable, and comparable with the CEUS modality in identification endoleaks after EVAR; it may be considered as a potential tool to monitor patients after EVAR implantation, especially those with renal insufficiency or with an allergy to any contrast media.
