CT-guided minimally-invasive penile fracture repair

ABSTRACT We present the case of a 28 year old patient with an incomplete tear of the tunica albuginea occurred after having sexual intercourse in the female superior position. The diagnostic assessment was performed first clinically, then with CT, owing to its high resolution, allowed to exactly detect the tear location leading to precise preoperative planning. After adequate diagnosis through imaging and proper planning, the patient was performed a selective minimally invasive surgical approach to repair the lesion. The patient had good erection with no angular deformity or plaque formation after a 3-month follow-up.

Anti-tumour immune effect of oral administration of Lactobacillus plantarum to CT26 tumour-bearing mice.

Colorectal cancer (CRC) is one of the most prevalent forms of cancer that shows a high mortality and increasing incidence. There are numerous successful treatment options for CRC, including surgery, chemotherapy, radiotherapy and immunotherapy; however, their side effects and limitations are considerable. Probiotics may be an effective strategy for preventing and inhibiting tumour growth through stimulation of host innate and adaptive immunity. We investigated and compared potential anti-tumour immune responses induced by two isolated Lactobacillus strains, Lactobacillus plantarum A and Lactobacillus rhamnosus b, by pre-inoculating mice with lactobacilli for 14 days. Subsequently, subcutaneous and orthotopic intestinal tumours were generated in the pre-inoculated mice using CT26 murine adenocarcinoma cells and were assessed for response against the tumour. Our results indicated that oral administration with L. plantarum inhibited CT26 cell growth in BALB/c mice and prolonged the survival time of tumour-bearing mice compared with mice administered L. rhamnosus. L. plantarum produced protective immunity against the challenge with CT26 cells by increasing the effector functions of CD8+ and natural killer (NK) cell infiltration into tumour tissue, up-regulation of IFN-γ (but not IL-4 or IL-17) production, and promotion of Th1-type CD4+ T differentiation. Consequently, our results suggest that L. plantarum can enhance the anti-tumour immune response and delay tumour formation.

Prevalence and molecular analysis of Anaplasma platys in dogs in Lara, Venezuela

Amostras de sangue coletadas de cães clinicamente sadios pertencentes ao exército da Venezuela e de seus treinadores foram analisadas pela técnica de PCR 16S rRNA específica para Anaplasma platys, A. phagocytophilum ou Ehrlichia ewingii. Dezesseis por cento (7/43) dos cães foram positivos, enquanto que todas as amostras de origem humana [25] foram negativas para A. platys. Todas as amostras, tanto de humanos quanto de caninos, foram negativas para E. ewingii ou A. phagocytophilum. Doze carrapatos da espécie Rhipicephalus sanguineus, coletados dos cães, foram negativos para A. platys pelo teste de PCR de transcricão reversa. As seqüênciasquase inteiras do gene 16S rRNA (1.364 pb) e do operon groESL (1.646 pb) de A. platys isolado de um cão foram determinadas, revelando que ambas as seqüências estão estreitamente relacionadas às seqüências de A. platys detectadas em carrapatos R. sanguineus na República Democrática do Congo.
