RESUMO
OBJECTIVES: To evaluate the efficacy of intraprostatic injection of prophylactic antibiotics for the prevention of infections following transrectal ultrasonography-guided prostate biopsy. METHODS: In this prospective interventional study, patients aged between 40 and 70 years with clinical indications for transrectal ultrasonography-guided prostate biopsy were enrolled. Consecutive patients who received intraprostatic injection of amikacin coupled with oral ciprofloxacin were compared with historical controls receiving only prophylactic oral fluoroquinolones prior to biopsy. Patients were followed for 7 days after biopsy for signs and symptoms of infection. RESULTS: A total of 210 patients were included in this study (mean age 65.7 ± 7.8 years). Among patients without intraprostatic injection, nine (8.6%) developed infectious complications (lower urinary tract infection in seven patients, and prostatitis in two), which led to hospitalization in six patients (5.7%). None of the patients who received intraprostatic antibiotic injection developed infectious complications. The difference in the incidence of post-transrectal ultrasonography-guided biopsy infections between the two groups was statistically significant (P = 0.003). CONCLUSION: Local intraprostatic antibiotic injection during transrectal ultrasonography-guided prostate biopsy adjuvant to oral fluoroquinolones can significantly reduce the rate of post-biopsy infectious complications.

We report the case of a 25-year-old female with renal arteriovenous fistula and pseudoaneurysm (PA) formation following renal core-needle biopsy, treated successfully by ultrasound-guided percutaneous embolization with autologous blood clot injection. After inserting a 15-gauge needle within the PA sac, 10 ml of blood was retrieved from the sac, and then reinjected into the PA as well as in the needle tract after the obtained blood completely clotted. The procedure was completed by manual compression of the flank. Follow-up sonographic examinations revealed no complication, and the PA size reduced gradually over time due to fibrotic shrinkage. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:592-596, 2017.

Quinoa (Chenopodium quinoa Willd.) has gained worldwide recognition for its nutritional values, adaptability to diverse environments, and genetic diversity. This review explores the current understanding of quinoa tolerance to environmental stress, focusing on drought, salinity, heat, heavy metals, and UV-B radiation. Although drought and salinity have been extensively studied, other stress factors remain underexplored. The ever-increasing incidence of abiotic stress, exacerbated by unpredictable weather patterns and climate change, underscores the importance of understanding quinoa's responses to these challenges. Global gene banks safeguard quinoa's genetic diversity, supporting breeding efforts to develop stress-tolerant varieties. Recent advances in genomics and molecular tools offer promising opportunities to improve stress tolerance and increase the yield potential of quinoa. Transcriptomic studies have shed light on the responses of quinoa to drought and salinity, yet further studies are needed to elucidate its resilience to other abiotic stresses. Quinoa's ability to thrive on poor soils and limited water resources makes it a sustainable option for land restoration and food security enterprises. In conclusion, quinoa is a versatile and robust crop with the potential to address food security challenges under environmental constraints.
RESUMO
We report and discuss a case of primary hydatidosis of the pelvic cavity in a woman who presented with severe weight loss and abdominal pain. This unusual presentation was initially considered as a tumor process until surgical exploration and microscopic studies confirmed the diagnosis. The gynecologists should be aware of possibility of primary hydatid cyst of the pelvic cavity and should be considered in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

PURPOSE: To determine the accuracy of ultrasound (US) and magnetic resonance imaging (MRI) in the diagnosis of penile fracture and preoperative mapping for modified surgical repair. METHODS: Twenty-five consecutive patients were included in the study prospectively over 29 months (from February 2014 to June 2016). US examination and MRI were performed on all patients and interpreted by two expert radiologists independently. The location of the defect in tunica albuginea was mapped onto a designed scheme preoperatively using each imaging modality. The detection rate, as well as agreement between preoperative radiologic mapping and surgical outcomes, was determined for each modality. RESULTS: The mean age of the patients was 28 ± 7.5 years. The most common etiology was intercourse (88%). The most common location of tunica albuginea rupture was mid-shaft of the penis (60%), and the mean length of tunica defects in their greatest dimension was 13.5 ± 3.95 mm. All patients had associated hematoma, but no urethral injury was detected. The detection rate of US and MRI was 88 and 100%, respectively. US mapped the tear location correctly in 18 patients [61 out of 75 items (81%); κ = 0.66], while MRI mapped it precisely in 23 patients [73 out of 75 items (97%); κ = 0.95]. CONCLUSION: Both modalities are extremely helpful for the diagnosis of penile fracture. Considering the cost-efficiency and accessibility of ultrasonography, US is recommended as the first-line tool for both diagnosis and preoperative mapping. MRI may be used as a complementary study in the patients for whom US fails to visualize or precisely define the tunica defect.

BACKGROUND: Cyst infections is not common in the patients with autosomal dominant polycystic kidney disease (ADPKD) however it may pose major problems to the clinicians because the diagnosis is hampered by lack of reliable imaging techniques for identification of the infected cysts and treatment may be difficult due to poor penetration of antibiotics into the cysts. CASE PRESENTATION: We present a case of ADPKD and intractable pyocysts that did not respond to standard antibiotic therapy but successfully treated by using ultrasound-guided cyst puncture, and repeated irrigation and drainage. CONCLUSION: Where the experienced interventional radiologists are available, this method can rescue these patients from nephrectomy.
RESUMO
Primary hydatid cyst of the parotid gland is extremely rare, even in the endemic areas. A 23-year-old woman presented with slowly progressive swelling in the right periauricular region. Computed tomography (CT) scan of the head and neck revealed a round, well-demarcated water-density mass in the right parotid gland. At the operation, the cystic mass replacing most of the superficial part of right parotid gland was demonstrated. Superficial parotidectomy was carried out. Histopathological examination confirmed the diagnosis of hydatid disease. CT scan is a valuable imaging method for diagnosis of parotid cystic lesions; however, other acquired and congenital cystic lesions of parotid gland may have similar appearance and should be differentiated. Where the incidence of the disease is high, hydatid cyst of parotid gland should be considered in the differential diagnosis of lesions causing swelling of the parotid area.
