Algorithm for predicting threshold retinopathy of prematurity is insufficient and fundus examinations are still needed before 31 weeks.

AIM: We evaluated the weight, insulin-like growth factor-1, neonatal, retinopathy of prematurity (WINROP) algorithm for very premature infants. METHOD: Infants born before 32 weeks who had undergone fundus examinations in the neonatal intensive care unit at the University Hospital of Nancy were included in this French retrospective cohort study from July 2012 to July 2016. We evaluated how well the WINROP software predicted threshold retinopathy of prematurity (ROP). RESULTS: We studied 570 infants with a mean gestational age of 28.7 ± 1.8 weeks and a mean birth weight of 1110 ± 297 g: 28.1% had ROP and 1.2% had threshold ROP. The overall WINROP sensitivity was 57.1%, specificity was 46.0%, predictive positive value was 1.3% and predictive negative value was 98.9%. At more than 30 weeks of gestation or 1250 g, these figures rose to a respective specificity of 100% and 95.7% and respective predictive negative value of 100% and 100%. There were independent associations between the severity of ROP and the Apgar score at five minutes, the duration of oxygen therapy and non-invasive ventilation. CONCLUSION: WINROP worked better on preterm infants born from 31 weeks onwards or weighing over 1250 g. Fundus examinations remain necessary for infants born earlier or lighter.

[Ipsilateral adrenalectomy in the surgical treatment of renal carcinoma]. / La surrénalectomie ipsilatérale dans le traitement chirurgical du carcinome rénal.

OBJECTIVES: To assess the value of ipsilateral adrenalectomy during radical nephrectomy for the treatment of renal cell carcinoma as a function of preoperative computed tomography findings. METHODS: Between May 1985 and June 1994, 194 patients underwent radical nephrectomy for renal cell carcinoma in our institution. Preoperative radiological reports and postoperative pathological reports were reviewed for 185 patients. RESULTS: 148 patients underwent abdominal computed tomography before surgery. 94 adrenalectomies were performed in this group of patients. None of the 77 patients in whom computed tomography showed a normal adrenal gland had adrenal metastasis on the definitive histological examination. 17 patients had an adrenal mass on computed tomography, 3 of which proved to be neoplastic. Preoperative CT had a sensitivity of 100%, a specificity of 82%, a positive predictive value of 18% and a negative predictive value of 100%. The 185 files reviewed included 114 adrenalectomies, including 4 adrenal glands invaded by renal cell carcinoma (3.5%). In these 4 cases, the smallest diameter of the renal tumour was 4 cm and the minimum pathological stage was T3. CONCLUSIONS: It therefore appears justified not to perform adrenalectomy during nephrectomy, in the presence of a renal tumour and negative adrenal computed tomography.

A multicenter, prospective, randomized clinical trial comparing tension-free vaginal tape surgery and no treatment for the management of stress urinary incontinence in elderly women.

AIMS: The aim of our study was to test the hypothesis that elderly women undergoing tension-free vaginal tape surgery (TVT) will have a better quality of life (QOL) and satisfaction compared to non-treated women despite age- and technique-related potential morbidity. METHODS: This multicenter, prospective, randomized, controlled trial enrolled a total of 69 women aged over 70 years who initially consented to be randomized to either undergo immediate TVT surgery or to wait for 6 months before submitting to the same surgery (control group). The main outcomes measured at every visit (pre-randomization, 8-12 weeks and 6 months) consisted of the Incontinence-Quality of Life (I-QOL) Questionnaire, the Patient Satisfaction Questionnaire and the Urinary Problems Self-assessment Questionnaire, among others. RESULTS: The analysis included 31 patients in the immediate surgery group and 27 subjects in the control group. Peri-operative complications in the immediate surgery group were bladder perforation (22.6%), urinary retention (12.9%), urinary tract infection (3.2%) and de novo urgency (3.2%). At 6 months, the mean I-QOL scores for the TVT and control groups were respectively 96.5 +/- 15.5 and 61.6 +/- 19.8 (P < 0.0001); mean Patient Satisfaction scores were respectively 8.0 +/- 2.7 and 2.0 +/- 2.4 (P < 0.0001); and mean Urinary Problems scores were respectively 4.5 +/- 4.3 and 11.6 +/- 3.5 (P < 0.0001). CONCLUSION: At 6 months post-randomization, the group of elderly women who underwent immediate TVT surgery showed a significant improvement in QOL, patient satisfaction and less urinary problems compared to the group of women waiting for the same surgery.

Induction of a stable morphological change in Propionibacterium freudenreichii.

When cells of Propionibacterium freudenreichii were incubated under fasting conditions and then plated in the presence of an inhibitor of protein synthesis, a variable but significant (greater than 10(-2) fraction of the population changed their morphology from rod to sphere, with a considerable thickening of the cell wall. This change was accompanied by metabolic and antibiotic-resistance modifications, including the synthesis of at least one new enzyme (alpha-glucosidase), and by the simultaneous appearance of several new species of DNA, presumably plasmids. The round cells grew faster than the parent strain and maintained their morphology indefinitely when propagated on complex medium containing glucose as the main carbon source. However, when glucose was omitted, cells returned to the rod form and regained their previous characteristics, including the absence of detectable plasmids.

[Recurrence and satisfaction levels following onysectomy with or without phenolization]. / Récidives et niveau de satisfaction post-onysectomie avec ou sans phénolisation.

OBJECTIVE: To compare recurrence and satisfaction levels among patients undergoing onysectomy with phenolization (OP) and without phenolization (OS). DESIGN: Retrospective cohort study. SETTING: Family practice unit. PARTICIPANTS: All patients (N = 35) undergoing onysectomy between September 1992 and May 1993, and between January 1996 and February 1997. MAIN OUTCOME MEASURES: Type of onysectomy (OP or OS) was taken from the patient's medical record. A telephone interview was used to determine whether patients had experienced recurrence; satisfaction was measured retrospectively at diagnosis, at time of surgery, and after surgery using a five-point scale (very unsatisfied to very satisfied). RESULTS: Among the 30 patients interviewed by telephone, four of the six patients in the OS group experienced recurrence, and four of the 24 patients in the OP group experienced recurrence. (Fisher's exact test, P = .007). In the OS group, satisfaction levels at diagnosis, during surgery, and after surgery were 4.7, 4.5, and 4.2, respectively. In the OP group, satisfaction levels at these three points were 4.3, 4.2, and 4.4, respectively. Notwithstanding technique used, a connection was noted between recurrence and satisfaction level at the time of the telephone interview (repeated measures test, P = .036). CONCLUSION: In general medicine, onysectomy with phenolization could be the treatment of choice for ingrown toenails.

Diagnostic accuracy of urinary cytology, and deoxyribonucleic acid flow cytometry and cytology on bladder washings during followup for bladder tumors.

PURPOSE: We evaluated the diagnostic accuracy of cytology on urine and bladder washings, and deoxyribonucleic acid (DNA) flow cytometry on bladder washings compared to cystoscopy during followup for bladder tumors. MATERIALS AND METHODS: A cross-sectional analysis was performed on 166 patients with a history of bladder tumor for the initial visit when cytology and DNA flow cytometry results were available for urine and bladder washing samples. There were 114 bladder tumor events and 52 negative controls (normal cystoscopy). A prospective study was conducted among the 66 patients with no tumor detected by cystoscopy at the initial visit and for whom the 3 test results were available. The patients were followed from this visit until tumor recurrence or the end of the followup period. Cytological examination was considered positive only when interpreted as malignant. Suspicious examinations were considered negative for the purpose of our study. RESULTS: Sensitivity and specificity of urinary cytology were 59 and 85%, respectively. Sensitivity was increased to 66% using bladder washing cytology whereas specificity was moderately decreased to 83%. The sensitivity and specificity of DNA aneuploidy were 45 and 87%, respectively. Inclusion within the aneuploid category of hyperdiploid samples (defined as more than 7% of cells in the S + G2M phase) increased sensitivity to 77%, while specificity decreased to 42%. Kaplan-Meier analysis of tumor-free survival in patients initially free of bladder cancer at cystoscopy showed an inability of DNA flow cytometry to predict recurrence, whereas positive urine or bladder washing cytology predicted a shorter time to recurrence (log-rank test p <0.01). CONCLUSIONS: These results show that DNA flow cytometry and cytology on bladder washing samples add little information to that obtained from voided urine cytology.
