Mourad Shonouda, Wafaa Osman
Little is known about ultrastructural alterations induced by heavy metals pollution in insects. Therefore, the main objective of the present study is to elucidate ultrastructural changes in sperm formation of the tenebrionid beetle, Blaps polycresta as a biomonitor of heavy metal soil pollution. Metal percentages in testicular tissues of adult insects collected from reference and polluted sites were estimated using energy-dispersive X-ray microanalysis (EDX). Only cadmium, among eight detected metals, showed significantly higher percentages in the polluted testes compared with the reference ones...

Following radical orchidectomy for testicular cancer, most patients undergo protocolled surveillance to detect tumour recurrences rather than receive adjuvant chemotherapy. Current United Kingdom national and most international guidelines recommend that patients require a chest x-ray (CXR) and serum tumour markers at each follow-up visit as well as regular CT scans; there is however, variation among cancer centres with follow-up protocols. Seminomas often do not cause tumour marker elevation; therefore, CT scans are the main diagnostic tool for detecting relapse...

INTRODUCTION: Puberty suppression using gonadotropin-releasing hormone agonists (GnRHas) is recommended by current guidelines as the treatment of choice for gender dysphoric adolescents. Although GnRHas have long been used to treat precocious puberty, there are few data on the efficacy and safety in gender dysphoric adolescents. Therefore, the Endocrine Society guideline recommends frequent monitoring of gonadotropins, sex steroids, and renal and liver function. AIM: To evaluate the efficacy and safety of GnRHa treatment to suppress puberty in gender dysphoric adolescents...

Testicular cancer is the most common cancer in young males. Testicular cancer has one of the highest cure rates of all cancers: with modern chemotherapy treatment five-year survival rate exceeds 90 percent overall, and reaches almost 100 percent in early stages. However, these favorable results can only be achieved if these patients are transferred to a reference center, because better outcome was reported for patients who had been treated in a high volume center. Strict adherence to therapeutic protocol is vital for good results...

Currently, seminomas account for about 60% of newly diagnosed testicular cancers in Germany, with an increasing trend. In lower tumor stages the main focus is on the avoidance of over therapy. This is of special interest in stage I where radiotherapy, carboplatin monotherapy and surveillance are available therapies as well as in stage IIA/B. Due to high late toxicity, radiotherapy of the retroperitoneal space is obsolete for young patients with clinical stage I and, in its present form, discussed controversially for patients with clinical stage IIA/B...

Testicular effects of chemical mixtures may differ from those of the individual chemical constituents. This study assessed the co-exposure effects of the model germ cell- and Sertoli cell-specific toxicants, X-irradiation (x-ray), and 2,5-hexanedione (HD), respectively. In high-dose studies, HD has been shown to attenuate x-ray-induced germ cell apoptosis. Adult rats were exposed to different levels of x-ray (0.5 Gy, 1 Gy, and 2 Gy) or HD (0.33%), either alone or in combination. To assess cell type-specific attenuation of x-ray effects with HD co-exposure, we used laser capture microdissection (LCM) to enrich the targeted cell population and examine a panel of apoptosis-related transcripts using PCR arrays...

BACKGROUND: Prostatic metastases from testicular germ cell tumors (TGCTs) are extremely uncommon. To the best of our knowledge, only five cases of prostatic metastases from seminoma have been reported in the literature. Conversely, no cases of metastases to the prostate from nonseminomatous germ cell tumors (NSGCT) have been previously reported. CASE PRESENTATION: We present two patients who developed prostatic metastases 5 and 21 years after the initial diagnosis...

The wide use of molecular positron emission tomography/computed tomography (PET/CT) imaging in the tumor diagnostics has been playing an important role recently. The clinical role of hybrid imaging (PET/CT, single photon ECT/CT (SPECT/CT)) is growing continuously due to the simultaneous imaging of anatomy and function. Regarding oncology the role of (18)F-fluorodeoxyglucose ((18)F-FDG) PET is proved in several clinical questions, including urooncology. Urologic cancers are associated with low or slightly significant uptake of FDG, due to their more benign behaviour...

OBJECTIVE: To study the clinical characteristics of yolk sac tumor of the testis with concomitant testicular hydrocele in children and the association between the two conditions in order to improve the diagnosis and treatment of the disease. METHODS: We retrospectively analyzed the clinical data of 7 cases of stage-I yolk sac tumor of the testis with concomitant testicular hydrocele. The patients ranged in age from 6 to 14 (mean 11) months. As treatment, we performed radical high spermatic cord orchiectomy after diagnosis established on intraoperative frozen sections, and conducted follow-up visits by medical examination, serum alpha-fetoprotein (AFP) detection, chest X-ray, ultrasonography and CT for 3-41 (mean 17) months, every month in the first year, every 3 months in the second year and every 6 months in the third year after surgery...

BACKGROUND: Bleomycin has become an integral part of chemotherapy in patients with germ-cell tumors. One of the most feared side effects is bleomycin-induced pneumonitis. In patients with mild or moderate BIP, radiological signs disappear almost completely within nine months after discontinuation of bleomycin treatment. CASE PRESENTATION: We present a patient with a history of non seminoma of the testis and bleomycin-induced pneumonitis. During follow-up, regression of the hypothesis of eosinophilic migration to the liver after regression of bleomycin-induced pneumonitis is highly suspicious based on transient eosinophilia and focal eosinophilic liver disease...

Positron emission tomography (PET) was developed in the mid-1970, and its initial applications were for heart and brain imaging research. Nowadays, this technology is aimed mainly at staging or restaging tumours as it allows the assessment of biochemical processes that are either specific or associated with tumour biology. The full appreciation of PET potentials and limitations among general practitioners and internists cannot be considered achieved and the appropriate use of PET especially when coupled to X-ray computed tomography (CT) is still suboptimal...

PURPOSE: Retroperitoneal lymph node dissection (RPLND) is performed in patients with advanced nonseminomatous (NSGCT) germ cell tumors and residual retroperitoneal mass post-chemotherapy. The extent of node dissection remains unclear. Ipsilateral template dissection is a compromise between morbidity and oncological efficacy. Here, we compare ipsilateral with primary bilateral laparoscopic (L)-RPLND after chemotherapy in terms of morbidity and oncological safety. PATIENTS AND METHODS: Nineteen laparoscopic ipsilateral L-RPLNDs (Group A) after platinum-based chemotherapy in patients with clinical stage IIA-III NSGCT were performed, while 20 patients underwent primary bilateral L-RPLND (Group B)...
