The Prospects of Organic Agriculture Development in the Chosen Regions of Poland – Podkarpacie and Kurpie

Organic farming is developing dynamically in the European Union. In Poland its growth is dynamic but still not on a wide scale. The area of organic farms has just exceeded 1%. Research shows that the main obstacles of the dynamic development of organic farming are lack of properly educated young farmers, lack of efficient distribution system of organic products in Poland and abroad and a lot of small farms of low productivity

Coexistence of Parry-Romberg syndrome with homolateral segmental vitiligo

Parry-Romberg syndrome or progressive facial hemiatrophy was first described by Caleb Parry in 1825 and Moritz Romberg in 1846. This disorder is characterized by slowly progressing acquired unilateral hemifacial atrophy, which affects subcutaneous tissue together with the muscles and underlying bones. The pathogenesis and precise incidence of the syndrome remain unclear. Immune-mediated processes and disturbed central regulation, leading to the hyperactivity of the sympathetic nervous system, are primarily considered in the pathogenesis of this disorder. Parry-Romberg syndrome and localized scleroderma are considered to be interrelated as both of them have a similar clinicopathological appearance. We report the case of a 46-year-old man affected by both progressive atrophy of the left side of the face and homolateral, segmental vitiligo in the left side of the trunk and face

Comparison of the incidence of skin cancers in patients on dialysis and after kidney transplantation

Introduction: Kidney transplant (KTx) patients on immunosuppressive therapy are predisposed to the development of infections and cancers. Aim: To compare the incidence and type of malignant skin lesions in kidney transplant patients and the dialyzed population based on the initiated dermatologic screening. Material and methods: The study included 598 patients: 486 kidney transplant recipients and 112 patients on maintenance dialysis. All the patients underwent dermatological examination. Only histologically confirmed cancers were included in this study. Age, gender and immunosuppressive therapy administration were also considered. Patients were followed up by a dermatologist for a period of 5 years. Results: Fifty-eight skin cancers; 39 basal cell carcinomas (BCC), 13 squamous cell carcinomas (SCC), 1 Bowen disease, 2 Kaposi sarcoma, 1 malignant melanoma, 1 Merkel cell carcinoma, and 1 fibrosarcoma protuberans were diagnosed in 30 (6.2%) kidney transplant patients, and 8 lesions (7 BCC and 1 SCC) were found in 4 (3.6%) patients on dialysis. Conclusions: The initiated dermatologic screening program indicates that the risk of skin cancer incidence in post kidney transplant patients receiving immunosuppressive therapy was significantly higher than in patients on dialysis

The level of proinflammatory cytokines : interleukins 12, 23, 17 and tumor necrosis factor \alpha in patients with metabolic syndrome accompanying severe psoriasis and psoriatic arthritis

Introduction: The incidence of metabolic syndrome is estimated at 15-24% in the general population and at 30-50% in patients with psoriasis. A probable cause of the described correlation is a constant release in chronic dermatosis of proinflammatory cytokines and their influence on individual systems and organs. Aim: Assessment of the concentration of the proinflammatory cytokines (IL-12, IL-23, IL-17 and $TNF-\alpha$) in blood serum and their correlation with the intensity of skin lesions, the presence of psoriatic arthritis and the risk of development of obesity and metabolic syndrome. Material and methods: The concentrations of subunit p70 IL-12, IL-17 and IL-23, and $TNF-\alpha$ in subjects with psoriasis and metabolic syndrome were determined. Results: The level of the studied cytokines, IL-17, IL-23 and $TNF-\alpha$ was higher in patients diagnosed with psoriasis. Higher levels of IL-17, IL-23 and $TNF-\alpha$ were observed in patients with metabolic syndrome accompanying psoriasis. A higher level of IL-17 and IL-23 was found in sera of patients with psoriatic arthritis in comparison to normal psoriasis. Conclusions: In the study, a higher level of IL-17 and IL-23 was also shown in patients with psoriatic arthritis in comparison to patients with normal psoriasis. The effectiveness of anti-IL12/23 drugs in psoriatic arthritis is a confirmation of the obtained results of the studies. Additionally, the increased level of IL-17, both in patients with metabolic syndrome and with psoriasis, could indirectly indicate an increased cardiovascular risk in patients with affected joints in comparison to psoriasis affecting only the skin

The role of focal infections in the pathogenesis of psoriasis and chronic urticaria

Introduction: The Focal Infection Theory, originally presented at the beginning of the 20th century, postulates that systemic diseases can be caused by microorganisms that arise from the focus of infection. Foci of infections have been described as sinuses, adenoids, tonsils, teeth, genitourinary tract, gall bladder and kidneys. A focus of infection is defined as the area that can occur in any part of the body, contains a pathogen (microorganism) and is usually asymptomatic. There are discordant opinions about the role of focal infections in the pathogenesis of psoriasis and urticaria. Aim: To establish whether there is a higher incidence of focal infections in patients with chronic urticaria and psoriasis. Material and methods: We retrospectively reviewed 129 patients with a history of psoriasis and chronic urticaria: 58 women and 71 men treated in the Department of Dermatology of the Jagiellonian University Medical College in Krakow. Results: In the analyzed group, 11 patients had a dental consultation, 58 - laryngological consultation and 29 women had a gynecological consultation. The most common examples of focal infection were tonsillitis, upper respiratory tract infections, sinusitis, dental caries and genitourinary tract infections. Aggravating factors were similar to previously described. Conclusions: A high incidence of focal infections in patients with psoriasis and urticaria suggests that infections may play a significant role in the pathogenesis of these skin disorders. Treatment of infection foci may play the key role in the remission of skin changes
