Relationships between CD34-, CD105- and bcl-2-Expression Levels and Contrast-Enhanced Ultrasound-Based Differential Diagnosis of Adnexal Tumours.

The relationships between CEUS parameters of adnexal tumours and postoperative immunohistochemical assessments of CD34, CD105 and bcl-2 were analysed. This study aimed to investigate whether contrast-enhanced ultrasonography (CEUS) parameters depend on the microvascular density of the tumour lesion found after surgery. Fifty-one patients with a diagnosis of adnexal tumours were included in this single-centre, prospective study. Participants underwent preoperative CEUS (contrast-enhanced ultrasound). Colour Doppler enhancement characterisation parameters (Ystart, Ymax and S) were determined. Immunohistochemical examination of histological specimens of the adnexal lesions was then carried out to determine the expression levels of the CD34, CD105 and bcl-2 proteins. Relationships between the aforementioned parameters were investigated. No significant statistical correlations were observed between CD34, CD105 and bcl2 expression levels and CEUS parameters, independently of whether the operated lesion was malignant or benign. Transvaginal CEUS is diagnostic for the detection of pathological neoplastic vascularisation of an adnexal lesion independent of the density of microcapillaries found postoperatively.

The Role and Place of Antioxidants in the Treatment of Male Infertility Caused by Varicocele.

The inability to become pregnant for at least 1 year despite regular unprotected intercourse may indicate infertility of one or both partners. This problem affects approximately 10-20% of couples worldwide, regardless of race, with male infertility reported to account for 25-60% of cases. Among the most common pathological causes of male infertility is the presence of varicocele and chronic infections of the male reproductive system. This study was performed using data collected at the Genesis Infertility Treatment Clinic, Bydgoszcz, Poland, between 1 January 2015 and 30 June 2017. A total of 163 men meeting the inclusion criteria were selected and divided into the idiopathic infertility group (78 men) and varicocele-related infertility group (85 men). All patients received treatment with a male fertility supplement containing a combination of 1725 mg of L-carnitine fumarate, 500 mg of acetyl-L-carnitine, 90 mg of vitamin C, 20 mg of coenzyme Q10, 10 mg of zinc, 200 µg of folic acid, 50 µg of selenium, and 1.5 µg of vitamin B12 (Proxeed® Plus, Sigma-Tau, Italy) twice a day for a period of 6 months from the time of the diagnosis of infertility. The treatment resulted in significant improvements in general semen parameters, particularly sperm count, sperm concentration, total motility, and progressive motility. This antioxidant therapy produced a particularly marked therapeutic benefit in patients with Grade III varicocele, with a greater improvement in progressive motility than in men with less severe or no varicocele. The use of the antioxidant preparation examined here seems reasonable in men with idiopathic infertility and as an adjuvant in those with varicocele-related infertility in whom surgical treatment has resulted in no improvement. Its use should be considered particularly in patients with Grade III varicocele who do not wish to undergo surgical treatment or in whom such a treatment is not possible for various reasons.

Fever as a factor contributing to long-term survival in a patient with metastatic melanoma: A case report.

BACKGROUND: Malignant melanoma is a cancer that arises from pigment cells in the skin called melanocytes. The long-term survival of a patient with advanced melanoma is rare. CASE: We present a unique case of a female patient who has suffered from malignant melanoma for more than 13 years. The disease progressed quickly, and 19 months after diagnosis, the patient was classified as having stage IV melanoma. After several years, the patient had several episodes of fever that were not deliberately treated with medication. After each episode of fever, the patient observed the disappearance of tumours, which was confirmed by medical examination. Interestingly, since her initial diagnosis, the patient has refused most of the proposed medical treatments. Consequently, only some of the surgical procedures were performed. Currently, despite the initially poor prognosis, the patient only suffers symptoms that are the result of surgical resection of brain metastases. Most of her malignant tumours either disappeared or have stabilized without further growth. CONCLUSIONS: The onset of fever has altered the typical and unfavourable course of melanoma, causing remission or at least stabilization. This observation, in accordance with others in this field, suggests that fever in cancer patients should not be treated immediately, but should be allowed to develop under the care of a physician.

Primary small intestine tumour as the cause of gastrointestinal tract occlusion.

The following paper presents the case of a 40-year-old patient staying in our Clinic between 2 March 2010 and 12 March 2010 due to the symptoms of permeable occlusion of gastrointestinal tract. This is a patient with a several weeks' history of non-specific abdominal pain, vomiting and significant weight loss (ca 20 kg). Until recently he has not suffered from any serious illnesses. In the performed abdominal ultrasound, gastroscopy and colonoscopy no pathology was affirmed. CT scan with intravenous and oral contrast showed significantly widened intestinal loops with residual liquid matter in the stomach, duodenum and a part of the jejunum without any distinguishing pathological mass, and also single mesenteric lymph nodes and para-aortic nodes enlarged to the size of 12 mm. The patient was qualified for laparatomy. During the surgery, a 4-cm tumour of the jejunum, concentrically narrowing intestinal lumen was found. Segmental resection of the small intestine was performed with side to side anastomosis with the use of a linear stapler. Currently the general condition of the patient is good, without any ailments, and the patient is undergoing systemic treatment.
