Oral lichen planus: a retrospective study of 633 patients from Bucharest, Romania

2012

Objective: In this retrospective study, patients’ medical records were reviewed to investigate the profiles of 633 OLP cases in a group of Romania. Material and Methods: In this retrospective study, the following clinical data were obtained from the medical charts of patients: gender, age, clinical presentation of OLP, site affected, presence of symptoms, extraoral manifestations of lichen planus, presence of systemic diseases, and history of medications. Results: Most (78.67%) OLP patients were female and the mean age at presentation was 52 years. The white type of the disease (reticular/papular/plaque lesions) was the main form encountered in this sample (48.97%). Among patients with avai…

Initial Experience with Radical Prostatectomy Following Holmium Laser Enucleation of the Prostate

2021

Background: Although an increasing number of prostate cancer (PCa) patients received holmium laser enucleation of the prostate (HoLEP) previously for benign prostatic obstruction (BPO), there is still no evidence regarding the outcomes of radical prostatectomy (RP) in this setting. Objective: To assess functional and oncological results of RP in PCa patients who received HoLEP for BPO previously in a contemporary multi-institutional cohort. Design, setting, and participants: A total of 95 patients who underwent RP between 2011 and 2019 and had a history of HoLEP were identified in two institutions. Functional as well as oncological follow-up was prospectively assessed and retrospectively an…

Study of three urethral pressure recording devices: Theoretical considerations

1978

Using a bladder-urethra model, 2 perfusion catheters (open side and open tip) were compared to the balloon catheter. The most accurate results were obtained using the balloon catheter. Based on the law of continuity and Bernouilli's law, the disadvantage of the open side catheter is due to the inconstant diameter of the sum of the side holes. Therefore, the measured pressure is not necessarily identical to the real pressure. The open tip catheter measures the opening pressure and the recorded pressure does not necessarily reflect the pressure at the site of the tip hole. The balloon catheter has elastic and plastic characteristics. Optimum results were obtained only with prestretch of the b…

Long-Term Followup of Children with Colon Conduit Urinary Diversion and Ureterosigmoidostomy

1977

Sixty-four children underwent colon conduit urinary diversion because of a neurogenic bladder owing to myelomeningocele and 39 children required a ureterosigmoidostomy because of bladder exstrophy. The average length of followup was 4.6 years after colon conduit and 5.6 years after ureterosigmoidostomy. Colon conduit diversion was secondary in 3 children and ureterosigmoidostomy was secondary in 5. Of the children with a colon conduit 9.4% and of those with ureterosigmoidostomy 12.8% had postoperative surgical complications. Late surgical complications were encountered after colon conduit in 14.5% and after ureterosigmoidostomy in 20%. Of the children with normal renal function preoperative…

Clinical profile of motor neuron disease patients with lower urinary tract symptoms and neurogenic bladder

2017

Introduction: Lower urinary tract symptoms (LUTS) are frequent in motor neuron disease (MND) patients, but clinical factors related to them are unknown. We describe differences in LUTS among MND phenotypes and their relationship with other clinical characteristics, including prognosis. Methods: For this study, we collected clinical data of a previously published cohort of patients diagnosed with classical amyotrophic lateral sclerosis (cALS), progressive muscular atrophy (PMA) or primary lateral sclerosis (PLS) with and without LUTS. Familial history was recorded and the C9ORF72 expansion was analysed in the entire cohort Patients were followed-up for survival until August 2016. Results: Fi…

Pregnenolone sulfate, a naturally occurring excitotoxin involved in delayed retinal cell death.

2002

The present study was designed to investigate the neurosteroid pregnenolone sulfate (PS), known for its ability to modulate NMDA receptors and interfere with acute excitotoxicity, in delayed retinal cell death. Three hours after exposure of the isolated and intact retina to a 30-min PS pulse, DNA fragmentation as assessed by genomic DNA gel electrophoresis and a modified in situ terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) method appeared concurrently with an increase in superoxide dismutase (SOD) activity and thiobarbituric acid-reactive substances (TBARS) levels. At 7 h, the increased amount of DNA laddering was accompanied by a higher number of TUN…

Recurrence of Acute Gallstone Pancreatitis and Relationship with Cholecystectomy or Endoscopic Sphincterotomy

2004

To determine the prevalence of recurrence of gallstone pancreatitis, its clinical features, and the presence of prognostic factors of recurrence.From January 1, 2000 to August 31, 2003, 233 patients admitted with acute gallstone pancreatitis (AGP) were prospectively studied. Patients were divided into two groups: recurrent and nonrecurrent group. Clinical, analytical, radiological, prognostic parameters, and severity (Atlanta criteria) were assessed, along with the performance of cholecystectomy or endoscopic sphincterotomy (ES). Clinical features of recurrence were analyzed. Univariate (chi(2), Student's t-test) and multivariate tests were performed. Statistical significance was assumed if…

How to Name Papillary Tumors of the Bladder in Children: Transitional Cell Carcinoma or Papillary Urothelial Neoplasm of Low Malignant Potential?

2015

Urinary bladder malignancies are uncommon in children. Approximately 80 children with papillary carcinoma have been described to date, presenting as papillary neoplasms of both low grade and low stage. On the basis of the 1973 World Health Organization classification, tumors were classified as transitional cell carcinoma of the urinary bladder (TCCB). Owing to more detailed histologic criteria, this term has been replaced by papillary urothelial neoplasm of low malignant potential and low-grade carcinoma of the urinary bladder in the World Health Organization-International Society of Urologic Pathology consensus classification system of urothelial neoplasms 2004. Nevertheless, TCCB still re…

[Clinical practice and adherence to the diagnosis and treatment of NMIBC guidelines: a report of a recognition based clinical cases study]

2014

For non-muscle invasive bladder cancer, a disease with a considerable epidemiological and socio-economic impact, the introduction of the Guidelines has always evoked as a tool for the resolution of long-standing disputes in terms of diagnosis and therapy. Check the degree of routine clinical practice adherence to the Recommendations is for this disease, more than for other uro-oncology pathology, an urgent need felt by the urological community. To assess the level of Guidelines adherence's, and study issues related to the paths of diagnosis and treatment of non-muscle invasive bladder cancer, and identifying the processes actually implemented in daily clinical practice, a series of case st…
