Stress urinary incontinence after labor and satisfaction with sex life

Objectives: The aim of the study was to assess the incidence of stress urinary incontinence in women after labor, its determinants, and to establish its effect on women’s satisfaction with their sex lives.  Material and methods: The research implemented the Gaudenz-Incontinence-Questionnaire and the Sexual Quality of Life-Female scale (SQoL-F). The principal inclusion criterion was the time of 3 to 6 months after labor.  Results: The research was carried out amongst 193 women. Thirty-two of the participants (16.6%) showed symptoms of stress urinary incontinence after labor that were statistically correlated with the number of experienced labors (p = 0.044) and the newborn’s weight (p = 0.016). The participants’ sex life satisfaction was on average 75.47 ± 24.68. The respondents suffering from stress urinary incontinence obtained a significantly lower (p = 0.006) average score for general sex life satisfaction (64.38 ± 26.15) when compared with women without symptoms of stress urinary incontinence (77.67 ± 23.86).  Conclusions: The problem of incontinence after labor affected one in six women. Occupation, number of pregnancies, damage to the perineum during labor, and the infant’s birth weight significantly dependent on the incontinence occurrence after labor. The onset of incontinence symptoms in women in the reproductive age has an adverse effect on their sex life satisfaction

In vivo biocompatibility assessment of (PTFE–PVDF–PP) terpolymer-based membrane with potential application for glaucoma treatment

The aim of the work was to evaluate the in vivo biological behaviour of polymeric membrane materials for glaucoma implants. The base material was biostable synthetic terpolymer (PTFE–PVDF–PP) with proved biocompability (PN-EN ISO 10993). The samples manufactured in the form a membrane were subjected to chemical and physical treatment to create an open pore system within the polymer matrix. As a porogenic phase biodegradable natrium alginate in a fibrous form was employed. The non-perforating deep sclerectomy technique was performed in a rabbit model. The clinical observations were made after 14 and 30 days. During the study clinical symptoms of a moderate degree were observed, and histopathological changes were typical for foreign body implantation. At the end stage of the study no significant difference in histopathological assessment was found between control and experimental group. Similarities observed in both groups and relatively mild histopathological changes in the tissue surrounding the implant indicate that the observed symptoms come from a deep scleral trauma caused by surgery, and not by the presence of the implant itself

Investigations on improvement of functionality of silicone ectoprostheses

Silikonowe protezy twarzy (epitezy, ektoprotezy, protezy zewnętrzne) stosowane są u pacjentów, którzy w wyniku zabiegu chirurgicznego, w ramach leczenia chorób nowotworowych, wad wrodzonych, urazu utracili tkanki miękkie i twarde w zakresie twarzoczaszki np. oko, ucho, nos. Rekonstrukcje protetyczne wykorzystuje się w przypadku, gdy metody chirurgii plastycznej są nieskuteczne lub nie mogą być zastosowane. Istnieją różne metody umocowania ektoprotez. Badania kliniczne i ankietowe wykazały, iż większość pacjentów w pierwszej kolejności wybierała kleje medyczne. Niestety kleje te charakteryzują się krótkim czasem trwałego przytwierdzenia protezy do miejsca ubytku. W pracy zbadano przyczepności trzech rodzajów materiałów silikonowych przytwierdzanych do skóry pacjentów za pomocą klejów i taśm komercyjnych. W celu poprawy adhezji tworzywa zastosowano dwa rodzaje modyfikacji powierzchni. Zbadano wpływ obróbki mechanicznej na powierzchnie silikonów (gwarantujący wzrost chropowatości powierzchni). Zbadano także skuteczność chemicznej metody obróbki powierzchni (trawienie tworzywa w roztworach kwasów nieorganicznych). Celem weryfikacji skuteczności zastosowanych metod modyfikujących powierzchnię opracowano metodę pomiaru adhezji pomiędzy materiałem polimerowym a badanym środkiem klejącym (taśma, klej) wykorzystując w tym celu układ uchwytów uniwersalnej maszyny wytrzymałościowej.Silicone facial prostheses (epitheses, ecto-prostheses, external prostheses) are applied for patients who lost soft and hard tissues in craniofacial area, e. g. eye, ear, nose, due to a surgical treatment; tumour diseases treatment; birth defects or injuries. Prosthetic reconstructions are used when plastic surgery methods are ineffective, or cannot be applied. There are various methods of the ecto-prostheses fastening. Clinical tests and surveys revealed that the first choice for the majority of patients is medical glues. However, such glues can provide only short-time fastening of prosthesis to the damaged area. The work presents results of investigations on adhesion of three kinds of silicone materials fastened to patients' skin with the use of commercial glues and adhesive tapes. In order to improve the materials' adhesion two methods of their surface modification were applied. Influence of a mechanical treatment on the materials' surface was investigated. Effectiveness of the surface chemical treatment i.e. etching of the materials with inorganic acids solutions was investigated. In order to verify effectiveness of the applied surface modification methods a testing method of adhesion between the material and the adhesive agent i.e. adhesive tape or glue was developed. The testing method utilised a universal testing machine

The following elements were taken under consideration: Mg, Ca, Zn, Fe, Pb. Their concentration was assessed in the articular cartilage harvested from the loaded an unloaded area of human femoral heads. Initial results indicate that mechanical loadings are one of the important factors influencing distribution of microelements in human articular cartilage

2D-Raman correlation spectroscopy as a method to recognize of the interaction at the interface of carbon layer and albumin

In modern nanomaterial production, including those for medical purposes, carbon based materials are important, due to their inert nature and interesting properties. The essential attribute for biomaterials is their biocompatibility, which indicates way of interactions with host cells and body fluids. The aim of our work was to analyze two types of model carbon layers differing primarily in topography, and developing their interactions with blood plasma proteins. The first layer was formed of pyrolytic carbon C (CVD) and the second was constructed of multi-walled carbon nanotubes obtained by electrophoretic deposition (EPD), both set on a Ti support. The performed complex studies of carbon layers demonstrate significant dissimilarities regarding their interaction with chosen blood proteins, and points to the differences related to the origin of a protein: whether it is animal or human. However the basic examinations, such as: wettability test and nano sctatch tests were not sufficient to explain the material properties. In contrast, Raman microspectroscopy thoroughly decodes the phenomena occurring at the carbon structures in contact with the selected blood proteins. The 2D correlation method selects the most intense interaction and points out the different mechanism of interactions of proteins with the nanocarbon surfaces and differentiation due to the nature of the protein and its source: animal or human. The 2D correlation of the Raman spectra of the MWCNT layer+HSA interphase proves an increase in albumin β-conformation. The presented results explain the unique properties of the Clayers (CVD) in contact with human albumin
