Natural cold pressed oils as cosmetic products
Background. It seems that patients may ask general practitioners about natural cosmetics applied on the skin regarding their safety and suitability.
Objectives. The aim of the study was to analyze natural cold pressed oils as potential cosmetic products.
Material and methods. Cold pressed oils obtained from selected seeds and fruit stones were analyzed, including: chokeberry seed oil, blackcurrant seed oil, elderberry seed oil, raspberry seed oil, apricot seed oil, tomato seed oil, strawberry seed oil, broccoli seed oil, Nigella sativa seed oil, hemp oil, safflower seed oil, Silybum marianum seed oil and coconut oil. 80 adult volunteers assessed the cosmetic properties of the analyzed oils. Each of the volunteers tested 2 to 4 different oils, by applying them on the skin. In addition, patch tests with all analyzed oils were performed on 23 individuals.
Results. The majority of tested oils were positively evaluated by the participants: in the opinion of the participants, oil extracted from safflower had the best appearance (100% positive opinions), coconut oil had the best smell (70% positive opinions), while black currant seed oil showed the best absorbency (85% positive opinions). No irritation was observed within the analyzed product group, albeit one allergic reaction to apricot seed oil was observed with patch testing.
Conclusions . Based on the achieved results, it could be suggested that natural cold pressed oils can be applied to the skin as cosmetics. Our observations may be helpful for general practitioners when choosing natural cosmetics
Analiza przypadków kiły wśród chorych hospitalizowanych w Klinice Dermatologii, Wenerologii i Alergologii we Wrocławiu w latach 2009–2016
Introduction: Syphilis is the systemic infectious disease caused by Treponema pallidum. It is a chronic process and has very rich symptomatology. Infection is possible by sexual contacts, bloodstream or transplacental.
Objective: The aim of our study was an objective analysis of the population infected by Treponema palladium based on medical documentation.
Material and methods: It was a retrospective analysis of medical documentation of the patients who were treated between 2009 and 2016 because of syphilis in the Department of Dermatology Venereology and Allergology in Wroclaw. A specially designed questionnaire consisting of questions about demographic data, medical history and present disease was completed. A total of 69 patients (43 men (62.3%) and 26 women (37.7%) (including 15 pregnant women)) were recruited for the study.
Results: Patients infected with syphilis belonged to various epidemiological groups. Early syphilis was diagnosed in 50.7% (n = 35) of patients, late syphilis in 46.4% (n = 32), whereas congenital syphilis was found in 2.9% (n = 2) of subjects. Regarding early syphilis, primary syphilis was observed in 17.1%, secondary syphilis in 54.3% whereas latent syphilis was found in 28.6% of patients. Latent late syphilis accounted for 81.2% of late syphilis cases, others manifested symptomatic late syphilis (18.8%). The primary lesions were observed by 29% of patients: 10 subjects found it on the penis, 4 in the oral cavity, 3 in the anus and 3 on the labia. Remarkably, 71% of patients did not notice the primary chancre. Syphilitic exanthema was observed by 39% of patients, condylomata lata by 2 patients, syphilitic angina by 3 persons, and syphilitic alopecia by 1 person. Recurrent febrile status was found in 4 patients.
Conclusions: Sexually transmitted diseases, especially syphilis, are still a very important medical problem. Despite the common access to penicillin, which allows to cure these disease, it appears that syphilis is still quite prevalent disease. To limit spreading of syphilis an early diagnosis, assurance of treatment and more widely distributed prevention programs are necessary.Wstęp: Kiła to ogólnoustrojowa choroba zakaźna wywoływana przez krętka bladego. Choroba przewlekły przebieg i bogatą symptomatologię, a zakażenie się nią jest możliwe drogą kontaktów seksualnych, przezłożyskową oraz przez zakażoną krew.
Cel badania: Celem badania była charakterystyka kliniczna pacjentów hospitalizowanych z powodu kiły w Klinice Dermatologii we Wrocławiu.
Materiał i metody: Retrospektywną analizę oparto o dokumentację medyczną pacjentów leczonych w latach 2009-2016 z powodu kiły w Klinice Dermatologii we Wrocławiu. Do badania włączono 69 chorych – 43 mężczyzn (62,3 %) i 26 kobiet (33,3 %) (w tym 15 kobiet ciężarnych).
Wyniki: Pacjenci chorujący na kiłę nie stanowili jednorodnej grupy epidemiologicznej. Przypadki kiły wczesnej stanowiły 50,7% (35 pacjentów), kiły późnej 46,4% (32 pacjentów), a wrodzonej 2,9% (2 dzieci). Wśród kiły wczesnej jedynie 17,1% to przypadki kiły I-rzędowej, natomiast odpowiednio 54,3% oraz 28,6% to przypadki kiły II-rzędowej i utajonej. Wśród pacjentów z kiłą późną postać utajona stanowiła aż 81,2%, a narządowa zaledwie 18,8%. Objaw pierwotny zgłosiło 29% pacjentów, z czego u 10 osób pojawił się on na prąciu, u 4 w jamie ustnej, u 3 w odbycie, u 3 na wargach sromowych, natomiast 71% nie zaobserwowało jego wystąpienia. Wystąpienie takiej osutki zgłosiło 39% badanych, kłykciny kiłowe płaskie 2 osoby, anginę kiłową 3 osoby, łysienie kiłowe 1 osoba oraz nawracające stany gorączkowe 4 osoby.
Wnioski: Choroby przenoszone drogą płciową, w szczególności kiła, w dalszym ciągu stanowią istotny problem medyczny. Mimo powszechnego dostępu do penicyliny, która umożliwia skuteczne leczenie kiły, nie udało jej się całkowicie wyeliminować. Lekarze nadal powinni wykazywać się czujnością, gdyż istotne jest postawienie wczesnej diagnozy, zapewnienie odpowiedniego leczenia, a także wdrożenie odpowiednich programów edukacyjnych, zwłaszcza wśród osób rozpoczynających współżycie seksualne.

Results: Oils with the highest content of omega-3 fatty acids were: elderberry oil (34.93%), strawberry seed oil (29.01%) and raspberry seed oil (22.31%). The highest concentration of omega-6 fatty acids was observed in safflower oil (75.11%), chokeberry seed oil (61.54%), and blackcurrant seed oil (61.48%). Analyzed oils also contained omega-9 acids, the ones with the highest percentage were broccoli seed oil (69.46%), apricot stone oil (68.16%), and tomato seed oil (29.67%). Omega-7 fatty acids constituted a small part of the total fatty acid content, e.g. tomato seed oil (4.09%), blackcurrant seed oil (1.4%) and broccoli seed oil (1.11%). Microbiological analysis has shown that 12 products were qualified as class 1 cosmetics, while coconut oil was assessed as class 2 cosmetic.
Conclusions: High concentration of polyunsaturated fatty acids enhances potential cosmetic properties of examined products, which can be used as cosmetics
Sixth taste – starch taste?
Scientists from Oregon State University, USA, came up with the newest theory of the sixth taste – starch taste that might soon
join the basic five tastes. This argument is supported by studies done on both animals and humans, the results of which seem
to indicate the existence of separate receptors for starch taste, others than for sweet taste. Starch is a glucose homopolymer
that forms an α-glucoside chain called glucosan or glucan. This polysaccharide constitutes the most important source
of carbohydrates in food. It can be found in groats, potatoes, legumes, grains, manioc and corn. Apart from its presence
in food, starch is also used in textile, pharmaceutical, cosmetic and stationery industries as well as in glue production.
This polysaccharide is made of an unbranched helical structure – amylose (15–20%), and a structure that forms branched
chains – amylopectin (80–85%). The starch structure, degree of its crystallisation or hydration as well as its availability
determine the speed of food-contained starch hydrolysis by amylase. So far, starch has been considered tasteless, but the
newest report shows that for people of different origins it is associated with various aliments specific for each culture.
Apart from a number of scientific experiments using sweet taste inhibitors, the existence of the sixth taste is also confirmed
by molecular studies. However, in order to officially include starch taste to the basic human tastes, it must fulfil certain
criteria. The aim of the study is to present contemporary views on starch
