Acute Glomerulonephritis in a Child with Chlamydia pneumoniae Infection: A Case Report.

Background. Infectious diseases seem to be an important and independent risk factor for renal failure, but the underlying mechanism of renal involvement during some kinds of infectious diseases is still unclear, even if the literature data report immunomediated and/or autoimmune mechanisms to explain the pathogenic relationship between the two diseases. In paediatric patients, Chlamydia pneumoniae is a rare cause of renal complications and it may manifest in several ways, mainly involving the respiratory system, even if also renal and glomerulalr complications, have been described. Case Diagnosis/Treatment. Herein we report a case of a 3-year-old child who developed an acute glomerulonephritis that was chronologically, clinically, and biologically related to a previous Chlamydia pneumoniae infection. On our knowledge, in the literature it is the youngest patient with renal involvement during course of Chlamydia pneumoniae infection ever reported. Conclusions. The present case supports the hypothesis of a rather close causal relationship between this infective agent and renal and glomerular symptoms occurred in this child, during an acute episode of respiratory disease

A Complex Renal Cyst: It Is Time to Call the Oncologist?

Introduction. Hydatid disease is a cyclozoonotic parasitic infestation caused by the cestode Echinococcus granulosus. The cysts mainly arise in the liver (50 to 70%) or lung (20 to 30%), but any other organ can be involved, in abdominal and pelvic locations, as well as in other less common sites, which may make both diagnosis and treatment more complex. Isolated renal involvement is extremely rare. Case Presentation. We report a rare case of isolated renal hydatid disease in a 71-year-old man with a history of vague abdominal pain, anemia, fever, and microhematuria. Ultrasonographic examination revealed a complex cyst in the right kidney, including multiple smaller cysts with internal echoes. A magnetic resonance scan of the abdomen confirmed the findings, and hydatid cyst disease was diagnosed. Right nephrectomy was performed, and microscopic examination confirmed the diagnosis of hydatid cyst. Albendazole, 10 mg/kg per day, was given for 4 weeks (2 weeks preoperatively and 2 weeks postoperatively). Conclusion. Isolated primary hydatidosis of the kidney should always be considered in the differential diagnosis of any cystic renal mass, even in the absence of accompanying involvement of liver or other visceral organs

Contemporary urologic minilaparoscopy : indications, techniques, and surgical outcomes in a multi-institutional European cohort

OBJECTIVES: To provide an analytical overview of contemporary indications, techniques, and outcomes of urologic minilaparoscopy (ML) in multiple European centers. METHODS: Data of patients who had undergone a minilaparoscopic urologic procedure at nine European institutions between 2009 and 2012 were retrospectively gathered. Surgical procedures were classified as upper or lower urinary tract and as ablative or extirpative and reconstructive. The main surgical outcome parameters were analyzed and relevant operative data related to the surgical technique were recorded. RESULTS: Overall, 192 patients (mean age 45.25±17.8 years) were included in the analysis. Most of them were nonobese (mean body mass index [BMI] 24.7±3.6?kg/m(2)) at low estimated surgical risk (mean American Society of Anesthesiologists [ASA] 1.69±0.68). Indications for surgery were mostly nononcologic (132 cases, 68.8%). Most of the procedures were done in the upper urinary tract (133 cases, 69.2%) and were mostly with a reconstructive intent (109 cases, 56.7%). Overall operative time was 132.7±52.3 minutes with an estimated blood loss of 60.9±47.6?mL while the mean hospital stay was 5±2.1 days. Most of the postoperative complications were low Clavien grade (1 and 2), with only one (0.5%) grade 3 and one (0.5%) grade 4 complications recorded. CONCLUSIONS: A broad range of common procedures can be safely and effectively performed with ML techniques. By duplicating the principles of standard laparoscopy, but potentially offering less surgical scar and trauma, ML can be regarded as a viable option when looking for a virtually "scarless" surgery

Laparoscopic and robotic ureteral stenosis repair: a multi-institutional experience with a long-term follow-up

The treatment of ureteral strictures represents a challenge due to the variability of aetiology, site and extension of the stricture; it ranges from an end-to-end anastomosis or reimplantation into the bladder with a Boari flap or Psoas Hitch. Traditionally, these procedures have been done using an open access, but minimally invasive approaches have gained acceptance. The aim of this study is to evaluate the safety and feasibility and perioperative results of minimally invasive surgery for the treatment of ureteral stenosis with a long-term follow-up. Data of 62 laparoscopic (n\uc2 =\uc2 36) and robotic (n\uc2 =\uc2 26) treatments for ureteral stenosis in 9 Italian centers were reviewed. Patients were followed according to the referring center\ue2\u80\u99s protocol. Laparoscopic and robotic approaches were compared. All the procedures were completed successfully without open conversion. Average estimated blood loss in the two groups was 91.2\uc2 \uc2\ub1\uc2 71.9\uc2 cc for the laparoscopic and 47.2\uc2 \uc2\ub1\uc2 32.3\uc2 cc for the robotic, respectively (p\uc2 =\uc2 0.004). Mean days of hospitalization were 5.9\uc2 \uc2\ub1\uc2 2.4 for the laparoscopic group and 7.6\uc2 \uc2\ub1\uc2 3.4 for the robotic group (p\uc2 =\uc2 0.006). No differences were found in terms of operative time and post-operative complications. After a median follow-up of 27\uc2 months, the robotic group yielded 2 stenosis recurrence, instead the laparoscopic group shows no cases of recurrence (p\uc2 =\uc2 0.091). Minimally invasive approach for ureteral stenosis is safe and feasible. Both robotic and pure laparoscopic approaches may offer good results in terms of perioperative outcomes, low incidence of complications and recurrence

Features of patients referring to the outpatient office due to benign prostatic hyperplasia: analysis of a national prospective cohort of 5815 cases

Background Evidence on clinical presentation of benign prostatic hyperplasia (BPH) is scarce, and studies involving outpatients are lacking. We aimed to provide an insight into the contemporary Italian scenario of BPH-affected outpatients using symptom scores (International Prostate Symptom Score [IPSS], BPH Impact Index [BII]), and to compare characteristics of patients with known BPH and those first-diagnosed at the visit. Methods "IMPROVING THE PATH" project working group designed a questionary prospectively administered to BPH-affected outpatients by urologists. A cross-sectional study was performed. Data were adjusted for patient age as a potential confounding factor. Results Of 5815 patients enrolled, BPH was already diagnosed in 4144 (71.3%), and not in 1671 (28.7%). Patients with known BPH, compared to newly diagnosed, were older (median 68 versus [vs] 55), had more frequent smoking (smoker 27.2 vs 22.6%, and ex-smoker 16.4 vs 12.5%) and drinking habits (55.4 vs 45.1%), were more frequently affected by hypertension (60.0 vs 42.4%), obesity (15.3 vs 9.6%), diabetes (17.9 vs 12.5%), and cardiovascular diseases (14.2 vs 9.5%), p < 0.001. At IPSS, moderate and severe symptoms correlated with already known BPH (56.1 vs 47.3% and 24.8 vs 7.8%), whereas newly diagnosed patients showed milder symptoms (44.9 vs 19.1%), all p < 0.001. At BII, concern for one's health and time lost due to urinary problems were higher in patients with known BPH (p < 0.001). For these patients, the urologist changes at least one of the ongoing medications in 63.5%. For patients newly diagnosed, supplements/phytotherapeutics, alpha-blockers, and 5-alfa reductase inhibitors were prescribed in 54.6%, 21.6%, and 7.1%, respectively. Conclusions Despite medical treatment, natural history of BPH leads to a progressive deterioration of symptoms. This may reflect the difference between newly diagnosed patients and those with known BPH in lifestyle and associated comorbidities. A healthy lifestyle and treatments including local anti-inflammatory agents may delay worsening of symptoms and improve quality of life

Natalizumab in multiple sclerosis: Discontinuation, progressive multifocal leukoencephalopathy and possible use in children

In the early 1990s, attention was drawn to the migration of immune cells into the central nervous system via the blood-brain barrier. The literature showed that lymphocytes binding to the endothelium were successfully inhibited by an antibody against 41 integrin. These biological findings resulted in the development of a humanized antibody to 4 integrin - natalizumab (NTZ) - to treat multiple sclerosis (MS). Here, we provide a systematic review and meta-analysis on the efficacy and safety of natalizumab, trying to answer the question whether its use may be recommended both in adult and in pediatric age groups as standard MS treatment. Our results highlight the improvement of clinical and radiological findings in treated patients (p<0.005), confirming NTZ efficacy. Nevertheless, if NTZ is shown to be efficient, further studies should be performed to evaluate its safety and to target the MS profile that could benefit from this treatment

What scientific information on the seismic risk to non-structural elements do people need to know? Part 2: tools for risk communication

The present paper describes the process of moving from a research study of most common vulnerable non-structural elements, to deliver solutions, tools and guidelines to improve understanding of and responsiveness to community concerns about seismic risk and non-structural elements.The observed damage to non-structural elements following recent earthquakes in Italy, Portugal and Iceland, were used for designing communication tools under the KnowRISK EU project for multi-stakeholders (students, business and citizens): the Practical Guide, the Students Short Guide, the KnowRISK Portfolio of Solutions, the Move, Protect and Secure video, the augmented reality apps, the maquettes, the students notebooks, videos, board games and hands-on tools. The philosophy behind these deliverables is that some risks, once identified, can be eliminated or reduced by informing people and suggesting preventive or emergency measures. These tools are devoted to improving the seismic performance of non-structural elements and to reduce the associated economic losses, loss of functionality, and potential threats to life safety. The rationale behind the selection of the information that people need to know for converting knowledge to more safety is discussed and a description of the transference of the findings of research to communication solutions is presented.The tools were planned following the engagement-model in risk communication to ensure that needs of communities and selected stakeholders were acknowledged, and that recipients are addressed in a way that appeals to them. Different media and communication channels such as print, television, online, face-to face communication and interviews were used for risk communication
