Sperm banking before gonadotoxic treatment: is it worth the effort? / 亚洲男科学杂志(英文版)

We aimed to compare the sperm quality in different cancer types and benign diseases before gonadotoxic treatment, and assess the usage rate of cryopreserved sperm for assisted reproductive treatment (ART). This retrospective study was conducted at two university clinics between January 2008 and July 2018. A total of 545 patients suffering from cancer or benign diseases were included in the study. The pretreatment sperm analyses were based on the World Health Organization (WHO) guidelines. Patients with testicular malignancy (TM) showed a significantly lower sperm count (median [interquartile range]: 18.7 × 10

Phenolic Composition and Inhibitory Ability of Methanolic Extract from Pumpkin (Cucurbita pepo L) Seeds on Fe-induced Thiobarbituric acid reactive species in Albino Rat’s Testicular Tissue In-Vitro.

Pumpkin seed has been associated with myriad of medicinal uses in different part of the world. In this study, phenolic composition and Fe2+ induced thiobarbituric acid reactive species (TBARS) inhibitory ability of methanolic extract from pumpkin seeds in rat’s testes homogenates were determined. The extract was prepared with 80% methanol (v/v) and the radicals [(1,1-diphenyl–2 picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS)] scavenging, Fe2+ chelation and ferric reducing abilities of the extract were carried out. The phenolics composition was also investigated using gas chromatography couple with flame ionization detector (GC-FID). The GC analysis revealed the presence of vallinic, coumaric protocatechuic, caffeic, ferulic and sinapinic acids, and apigenin, quercetin, luteolin, kaempferol as the dominant phenolic compounds. The results revealed that the extract inhibited Fe2+-induced TBARS, scavenge DPPH radical and chelate Fe2+ in a dose dependent manner. The extract also scavenged ABTS radical and reduced Fe2+ to Fe3+. Although, the standard used had higher effect compared to the extract, nevertheless, the TBARs inhibitory potential of the extracts clearly gives an insight on the protective potentials against oxidative induce testicular damage that might lead to male infertility if unchecked. These abilities could however be linked to the presence of polyphenolic compounds.

Acoustic radiation force impulse (ARFI) elastography of testicular disorders in dogs: preliminary results / Elastografia acoustic radiation force impulse (ARFI) de afecções testiculares em cães: resultados iniciais

The aim of this study was to describe the use of acoustic radiation force impulse (ARFI) elastography in the evaluation of testicular disorders in dogs. Eighteen dogs with testicular disorders (thirty-six testicles) were assessed. Echotexture, size, contours and margins of testes were analysed by ultrasonography. Deformities and tissue stiffness (greyscale and homogenous or heterogeneous) were evaluated by qualitative elastography and shear velocity was determined quantitatively. Subsequent to orchiectomy, testicular samples were collected for histopathology analysis and thirty-six disorders were identified. Qualitative elastography revealed that normal healthy testicular tissues were homogenous and not pliable while the affected testicles had alterations in tissue stiffness and homogeneity. The values obtained for quantitative elastography of the testicular tissues were: normal/healthy - 1.30±0.12 m/s; degenerated - 0.97±0.08 m/s; atrophied - 2.00±0.35 m/s; hypoplastic - 0.82±0.2 m/s; cystic - 1.32±0.18 m/s; orchitis - 2.68±0.42 m/s; interstitial cell tumours - 3.32±0.65 m/s; sertolioma - 2.99±0.07 m/s and leydigoma - 2.73±0.37. ARFI elastography of abnormal testes proved to be an applicable and complementary technique in the diagnosis of testicular disease in dogs.

O objetivo deste estudo foi descrever o uso da elastografia ARFI (acoustic radiation force impulse) para avaliar as afecções testiculares em cães. Dezoito cães com distúrbios testiculares (36 testículos) foram avaliados. Ecotextura, tamanho, contornos e margens dos testículos foram avaliados por meio da ultrassonografia modo-B. A presença de deformidades e a rigidez tecidual (escala de cinza; homogênea ou heterogênea) foram avaliadas pela elastografia qualitativa; e a velocidade de cisalhamento foi determinada pela avaliação quantitativa. Amostras dos tecidos testiculares foram coletadas após orquiectomia para o diagnóstico histopatológico. Após ultrassonografia, orquiectomia e histopatologia, foram identificados 36 distúrbios em tecidos testiculares. Durante a elastografia qualitativa, os tecidos normais apresentaram-se homogêneos e não deformáveis; os testículos alterados demonstraram alterações na rigidez tecidual e de sua homogeneidade. Para a elastografia quantitativa, os valores obtidos foram: tecidos normais - 1,30±0,12m/s; degenerados - 0,97±0,08m/s; atrofiados - 2,00±0,35m/s; hipoplásicos - 0,82±0,2m/s; cistos - 1,32±0,18m/s; orquite - 2,68±0,42m/s; tumores de células intersticiais - 3,32±0,65m/s; sertolioma - 2,99±0,07m/s; e leydigoma - 2,73±0,37m/s. A elastografia ARFI de testículos anormais em cães demonstrou ser uma técnica aplicável e complementar para o diagnóstico de doenças testiculares nessa espécie animal.

Overt testicular disease at diagnosis in childhood acute lymphoblastic leukemia: Prognostic significance and role of testicular irradiation.

Objective. To analyze the prognostic impact of overt testicular disease (OTD) at diagnosis and role of testicular irradiation in the same. Methods. Data of 579 boys treated at our center over 16 years was reviewed. Results. Fourteen (2.4%) males had OTD. 10 (71.4%) of these had high-risk disease. Patients with OTD, had a significantly higher incidence of mediastinal-adenopathy (p=0.001), hyperleucocytosis (p=0.004) and CNS disease at presentation (p<0.0001) compared to patients in continuous complete remission (CCR). 4 of the 11 patients with OTD, who opted for therapy, had relapse; 2 are in CCR. Although, survival in patients with OTD was inferior (p=0.183) compared to patients without OTD, it was not an independent prognostic factor (p=0.47). In the entire study cohort, symptom-diagnosis interval (p=0.006), white cell (p=0.001) and platelet count (p=0.001) at presentation were significantly associated with survival (Cox multivariate regression analysis). Conclusions. OTD was not an independent prognostic factor, despite association with high-risk features. Survival outcome was inferior. The observations indicate the need of revaluation of the present protocol with incorporation of intermediate dose and subsequently high-dose methotrexate (after assessment for toxicity and tolerance), risk-stratified therapy and plausibly omission of testicular irradiation.

Hidrocele abdominoescrotal em lactente / Abdominoscrotal hydrocele in infants

Os autores relatam um caso de hidrocele abdominoescrotal em um lactente. É forma rara de hidrocele, que ocorre em crianças e adultos. A causa não está esclarecida, e o diagnóstico é clínico. O tratamento dessa doença é cirúrgico e deve ser precoce a fim de evitar o aparecimento de complicações.

The authors report a case of abdominoescrotal hydrocele in an infant. It is a rare sort of hydrocele that occurs in children and adults. The cause is not clear and the diagnosis is clinical. The treatment of that disease is surgical and it should be early enough in order to avoid the appearance of complications.
