Extraperitoneal Laparoscopic Approach in Inguinal Hernia-The Ideal Solution?

BACKGROUND: After more than 20 years since laparoscopy was proposed as a solution for one of the most common surgical pathologies, inguinal hernia, the choice of an intra- or extraperitoneal approach has remained a highly debated topic. PURPOSE AND OBJECTIVES: This study aimed at analyzing the feasibility of the extraperitoneal approach, by routine for this team/ and answering the question of whether this type of approach can be considered a safe one. Although indications for an intra- or extraperitoneal approach largely overlap, it may also be a matter of surgeon preference in choosing one technique. METHODS: The study was retrospective, conducted on a group of 493 patients operated on for inguinal hernia in the clinic, by a single operating team, between January 2012 and March 2022. RESULTS: It was proven that out of the 493 surgeries for inguinal hernia, 95.1% (n = 469) were operated upon by laparoscopic TEP (total extra peritoneal patch plasty approach); 1.62% (n = 8) by laparoscopic TAPP (transabdominal intraperitoneal); and 3.24% (n = 16) by the open, anterior approach (Lichtenstein). There were no intraoperative complications recorded in any of the procedures, while postoperative complications were found in 10.23% of cases (n = 48) in the extraperitoneal approach, and recurrences after the TEP approach were recorded in 0.40% of cases (n = 2). CONCLUSIONS: For correctly selected cases, TEP hernia surgery can be considered a safe and reliable approach.

Oversight and Management of Women with Psoriasis in Childbearing Age.

Psoriasis is a complex disease with many associated comorbidities, all of which have a negative impact on a patient's personal, social, and sexual life. There are some unique considerations in the effects of this disease among women. The average age of diagnosis in women with psoriasis is 28 years, and this onset corresponds to the fertile life of women. There is conflicting information about the effects of psoriasis on female fertility. Some studies suggest that this condition's associated comorbidities, personal behaviors, and reduced ovarian reserve, especially due to chronic inflammation, affect women's fertility. Another possible reason women with psoriasis are less likely to become pregnant is that their sexual intercourse frequency decreases after the condition's onset. The available information on the effects of pregnancy on women with psoriasis is limited. According to current evidence, most women will experience an improvement in their skin condition. Studies show that patients with moderate-to-severe psoriasis are more prone to experience pregnancy complications. The management of pregnant and lactating women with psoriasis is also difficult, as the safety profile of commonly used drugs in patients with psoriasis is not entirely known.

The Role and Significance of Bioumoral Markers in Prostate Cancer.

The prostate is one of the most clinically accessible internal organs of the genitourinary tract in men. For decades, the only method of screening for prostate cancer (PCa) has been digital rectal examination of 1990s significantly increased the incidence and prevalence of PCa and consequently the morbidity and mortality associated with this disease. In addition, the different types of oncology treatment methods have been linked to specific complications and side effects, which would affect the patient's quality of life. In the first two decades of the 21st century, over-detection and over-treatment of PCa patients has generated enormous costs for health systems, especially in Europe and the United States. The Prostate Specific Antigen (PSA) is still the most common and accessible screening blood test for PCa, but with low sensibility and specificity at lower values (<10 ng/mL). Therefore, in order to avoid unnecessary biopsies, several screening tests (blood, urine, or genetic) have been developed. This review analyzes the most used bioumoral markers for PCa screening and also those that could predict the evolution of metastases of patients diagnosed with PCa.

Animal Models in Bladder Cancer.

BACKGROUND: Bladder cancer (urothelial cancer of the bladder) is the most common malignancy affecting the urinary system with an increasing incidence and mortality. Mouse models of bladder cancer should possess a high value of reproducibility, predictability, and translatability to allow mechanistic, chemo-preventive, and therapeutic studies that can be furthered into human clinical trials. OBJECTIVES: To provide an overview and resources on the origin, molecular and pathological characteristics of commonly used animal models in bladder cancer. METHODS: A PubMed and Web of Science search was performed for relevant articles published between 1980 and 2021 using words such as: "bladder" and/or "urothelial carcinoma" and animal models. Animal models of bladder cancer can be categorized as autochthonous (spontaneous) and non-autochthonous (transplantable). The first are either chemically induced models or genetically engineered models. The transplantable models can be further subclassified as syngeneic (murine bladder cancer cells implanted into immunocompetent or transgenic mice) and xenografts (human bladder cancer cells implanted into immune-deficient mice). These models can be further divided-based on the site of the tumor-as orthotopic (tumor growth occurs within the bladder) and heterotopic (tumor growth occurs outside of the bladder).

Prevalence and Characteristics of Psoriasis in Romania-First Study in Overall Population.

Background: Psoriasis is a chronic inflammatory disease characterized by an excessive hyperproliferation of keratinocytes and a combination of genetic, epigenetic, and environmental influences. The pathogenesis of psoriasis is complex and the exact mechanism remains elusive. Objectives: The study of the prevalence of psoriasis will allow the estimation of the number of people suffering from this condition at the national level, as well as the development and validation of a questionnaire to estimate the prevalence and the risk factors associated with the disease. Methods: A quantitative research was conducted at a national level among the target population in order to validate the questionnaire and estimate the national prevalence. Results: Declaratively, the prevalence of psoriasis in the studied group (N = 1500) is 4%, the first symptoms appearing around the age of 50, with a certified diagnosis being made on average at 55 years. The prevalence of psoriasis vulgaris was 4.99%. Conclusions: The results obtained will be useful in guiding future initiatives and communication campaigns related to this condition, and the methodological approach used will provide the opportunity to make recommendations for improving similar initiatives in the future.

Biochemical and cytogenetical study of the mycoplasmal antigen and of the cyclophosphamide action in mammalians, in vivo. The action of some immunomodulatory antioxidants.

It was proved spectrophotometrically that Mycoplasma agalactiae antigen inoculated in vivo in sheep modifies the corresponding erythrocyte lysates reactivity toward methylene blue and neutral red and induces several types of chromosomal rearrangements. The treatment in vivo of sheep with an original preparation obtained from the Phaseolus vulgaris pods restores the erythrocyte lysates reactivity toward the two redox dyes and reduces the chromosomal abnormalities frequency induced by the mycoplasmal antigen. It was also demonstrated by optical and electronical microscopy that the Smise line mouse meiocytes exhibit chromosomal abnormalities induced by the cyclophosphamide treatment in vivo. In the case of concomitant treatment with the cyclophosphamide and C vitamin the same frequency of abnormalities was recorded as in the simple treatment with the drug.

Pancreatic B-cell culture after intravitam B-cell selection with nitric pilocarpine and modified B-technique use.

Our purpose was intravitam selection of endocrine pancreatic tissue. We decided to use 3% nitric pilocarpine as oral treatment for normal Wistar rats. This experiment was made on 12 male normal Wistar rats, 8 of them receiving 0.025 ml 3% nitric pilocarpine in a single daily dose, for 7 days. In the next 3-4 days, all of these have demonstrated clinical picture of exocrine pancreatic failure leading finally to death. Animals have received ad libitum food-intake. During this period, the study group has demonstrated glycemia values between 65...75 mg/dl vs. 68...85 mg/dl for normal group. The histological picture of study group's pancreatic pieces demonstrated intensive necrobiotic changes for exocrine components, but normal features for the exocrine ones. Furthermore we have obtained primary monolayer cultures of this dominant B-cell tissue, using a modified B-technique. Our results demonstrated the greatest percentage of B-cells on the cultures, in comparison with the non-using pilocarpine method (other studies). The presence of mega-beta-islet cells in primary cultures, as well as the lack of fibroblast population, demonstrated the efficiency of this method.
