Management of a Case of Colovesical Fistula with Fecaluria as First Sign
Introduction. Fecaluria and pneumaturia are the patognomonic signs of an abnormal communication between the bladder and the intestinal tract. Therefore, when a history of digestive signs, symptoms or digestive diseases is missing, this borderline pathology leads the patients in the care of urologists. From diagnosis to treatment the management of these cases can be difficult and challenging.
Materials and Methods. A 48 year old patient, without any significant medical history, presented to the emergency room for fecaluria, pneumaturia and an episode of haematuria. He had no prior digestive symptoms. The contrast enhanced abdominal and pelvic CT scan revealed a pelvic mass involving the sigmoid colon and the dome and the posterior wall of the bladder. The cystoscopy objectifies a tumor mass involving the right postero-lateral bladder wall, with extravasation of faeces. A biopsy was taken and the frozen section found mainly uncertain inflammatory type tissue. A colonoscopy couldn’t be done because of an impassable obstacle at 15 cm from the anus. Together with general surgeons we decided for en bloc resection of the tumor with partial cystectomy, right ureterocystoneostomy and rectosigmoid resection with mechanic end to end anastomosis.
Results. The postoperative period was uneventful. The histopathological examination revealed an abscessed sigmoid diverticulum with vesico-sigmoid fistula and perilesional inflammatory tissue. Two years after the surgery the patient is asymptomatic with a normal function of the right kidney and restored bladder capacity.
Conclusions. Being a borderline pathology, patients with fecaluria and pneumaturia and lack of digestive symptoms are referred and managed by the urologists. Despite extensive investigations, even when preoperative biopsies reveal inflammatory tissue the patients should be treated as oncologic cases. A close cooperation with general surgeons for en bloc multiorgan resection within oncologic safety margins is mandatory
The efficacy of angiotensin–I receptor blocker Valsartan in patients with cronic obstructive lung disease
Department of Chronic Obstructive Pulmonary Disease, Chiril Draganiuc Institute of Phthysiopulmonology, Department of Functional Diagnostic, Republican Diagnostic Medical Center, Chisinau, the Republic of MoldovaBackground: The purpose of this study was the clinical, functional and instrumental evaluation of efficacy and safety of angiotensin-I receptor
blocker Valsartan in patients with chronic obstructive pulmonary disease.
Material and methods: There were investigated 25 patients (mean age 50.5 ± 4.34 years) with moderate to severe forms of obstructive lung disease
– initial and after 5 weeks of treatment with angiotensin – I receptor blocker Valsartan (Nortivan, ,,Gedeon Richter’’, Hungary), mean dose 54.5 ± 15.4
mg once-daily, using standard ECG, EchoCG with Doppler, bodyplethysmography, ultrasound Doppler (for endothelial function estimation), pulmonary
diffusion capacity for CO, cycloergometry - initial and after short – term treatment with Nortivan.
Results: There were not detected any negative changes on bronchial permeability after the treatment. Significant improvement of endothelial function,
pulmonary diffusion capacity, parallel with considerable decreasing of pulmonary artery systolic and mean pressure and total bronchial resistance – were
observed after 5 weeks of treatment.
Conclusions: Nortivan is well-tolerated and highly effective in patients with moderate to severe forms of obstructive lung disease

Observation an comparison of mealtime behaviours in a sample of children with avoidant/restrictive food intake disorders and a control sample of children with typical development
Objectives: Despite widespread use of behavioural observations to evaluate child feeding behaviours in research and clinical practice, few studies have comprehensively characterised mealtimes or identified features that differentiate children with and without disordered feeding; these were the aims of the current study.
Methods: Mealtime observations were conducted for 18 children with Avoidant Restrictive Food Intake Disorder (ARFID) and 21 typically developing children. Observations were coded inductively, and associations between disorder and observed mealtime actions were examined.
Results: Most behaviours were observed across both clinical and non-clinical mealtimes, and many did not differ in frequency between children with and without ARFID. However, significant group differences were observed in the frequencies of behaviours relating to food intake, visual and physical engagement with feeding, and movement during mealtimes.
Conclusions: The comparability of behaviours across clinical and non-clinical groups suggests that eating behaviours exist on a continuum from ‘normal’ to ‘abnormal’, with group differences relating to frequency rather than type of behaviour. The behavioural differences observed in this study suggest that identification of children with ARFID should focus on child engagement with food and restlessness during mealtimes. Reliance on emotional and escape-maintained behaviours will lead to under-recognition of families in need of clinical support

Lymphomas with kidney involvement: the French multicenter retrospective LyKID study.
The LyKID study is a nationwide survey in France of lymphoma patients with renal involvement based on biopsy and/or imaging, to evaluate its impact on disease outcome and renal function. A total of 87 adult cases of B or T-cell lymphomas were retrospectively analyzed. Interstitial topography was observed in most of the kidney biopsies (54/66; 80%). Kidney failure (glomerular filtration rate <60 mL/min/1.73 m <sup>2</sup> ) was present in 47% of patients and was associated with non-significantly different outcome. After lymphoma treatment, 44% of patients had persistent chronic kidney failure (CKF); kidney failure at diagnosis was the only parameter associated with CKF in multivariate analysis. DLBCL (diffuse large B-cell lymphomas) represented half of the series, with noticeably CNS (central neurological system) relapse in 17% patients, while fewer than one of two patients had received CNS prophylaxis. To our knowledge, the LyKID study represents the largest published non-autopsy lymphoma series with renal involvement
Loss of NDR1/2 kinases impairs endomembrane trafficking and autophagy leading to neurodegeneration.
Autophagy is essential for neuronal development and its deregulation contributes to neurodegenerative diseases. NDR1 and NDR2 are highly conserved kinases, implicated in neuronal development, mitochondrial health and autophagy, but how they affect mammalian brain development in vivo is not known. Using single and double Ndr1/2 knockout mouse models, we show that only dual loss of Ndr1/2 in neurons causes neurodegeneration. This phenotype was present when NDR kinases were deleted both during embryonic development, as well as in adult mice. Proteomic and phosphoproteomic comparisons between Ndr1/2 knockout and control brains revealed novel kinase substrates and indicated that endocytosis is significantly affected in the absence of NDR1/2. We validated the endocytic protein Raph1/Lpd1, as a novel NDR1/2 substrate, and showed that both NDR1/2 and Raph1 are critical for endocytosis and membrane recycling. In NDR1/2 knockout brains, we observed prominent accumulation of transferrin receptor, p62 and ubiquitinated proteins, indicative of a major impairment of protein homeostasis. Furthermore, the levels of LC3-positive autophagosomes were reduced in knockout neurons, implying that reduced autophagy efficiency mediates p62 accumulation and neurotoxicity. Mechanistically, pronounced mislocalisation of the transmembrane autophagy protein ATG9A at the neuronal periphery, impaired axonal ATG9A trafficking and increased ATG9A surface levels further confirm defects in membrane trafficking, and could underlie the impairment in autophagy. We provide novel insight into the roles of NDR1/2 kinases in maintaining neuronal health
