Retropubic tape surgery for stress urinary incontinence: can women be cured without voiding dysfunction?

PURPOSE: Retropubic tension free vaginal tape (RP-TVT) has become the gold standard for surgical management of female stress urinary incontinence but is associated with voiding dysfunction (VD). We developed for more than 10 years a reproductible and totally tension free tape procedure. Our goal is to determine efficiency of this technique compared to the incidence of VD. METHODS: We retrospectively reviewed patients who underwent RP-TVT in our center between 2011 and 2019. Subjective cure, VD (determined as maximum urinary flow rate (Qmax) < 15 mL/s or post void residual (PVR) volume > 150 mL, or tape's section or resection requirement for underactive bladder (UB) with significant PVR) was assessed at 1 year. The main objective was the evaluation of subjective cure and VD at 1 year. RESULTS: On the 319 patients reviewed, 93% of the patients were dry and 10.9% presented VD at one year. UB (OR = 5.01 [1.55-16.44], p = 0.008), preoperative Qmax < 15 mL/s (OR = 0.89 [0.84-0.95], p = 0.001) and previous incontinence surgery (OR = 4.20 [1.54-11.46], p = 0.005) were associated with VD. Acute urinary retention concerned 4.7% of the population and all were resolved after 6 weeks postoperatively. We reported 0.3% of de novo urgency and patients without VD showed a significant decrease of their voiding time at 1 year. CONCLUSION: The placement of RP-TVT without intraoperative tightening seems to be a safe technique ensuring a high cure rate and low occurrences of bladder outlet obstruction.

French AFU Cancer Committee Guidelines - Update 2022-2024: management of kidney cancer.

AIM: To update the recommendations for the management of kidney cancers. METHODS: A systematic review of the literature was conducted from 2015 to 2022. The most relevant articles on the diagnosis, classification, surgical treatment, medical treatment and follow-up of kidney cancer were selected and incorporated into the recommendations. Therefore, the recommendations were updated while specifying the level of evidence (high or low). RESULTS: The gold standard for the diagnosis and evaluation of kidney cancer is contrast-enhanced chest and abdominal CT. MRI and contrast-enhanced ultrasound are indicated in special cases. Percutaneous biopsy is recommended in situations where the results will influence the therapeutic decision. Renal tumours should be classified according to the pTNM 2017 classification, the WHO 2022 classification and the ISUP nucleolar grade. Metastatic kidney cancer should be classified according to the IMDC criteria. Partial nephrectomy is the gold standard treatment for T1a tumours and can be performed by an open approach, by laparoscopy or by robot-guidance. Active surveillance of tumours less than 2cm in size can be considered regardless of the patient's age. Ablative therapies and active surveillance are options in elderly patients with comorbidity. T1b tumours should be treated by partial or radical nephrectomy depending on the complexity of the tumour. Radical nephrectomy is the first-line treatment for locally advanced cancers. Adjuvant treatment with pembrolizumab should be considered in patients at intermediate and high risk for recurrence after nephrectomy. In metastatic patients: Immediate cytoreductive nephrectomy may be offered to oligometastatic patients in combination with local treatment of metastases if this can be complete and delayed cytoreductive nephrectomy can be proposed for patients with a complete response or a significant partial response. Medical treatment should be proposed as first-line therapy for patients with a poor or intermediate prognosis. Surgical or local treatment of metastases can be proposed in case of single or oligo-metastases. The recommended first-line drugs for metastatic patients with clear cell renal carcinoma are the combinations axitinib/pembrolizumab, nivolumab/ipililumab, nivolumab/cabozantinib and lenvatinib/pembrolizumab. Cabozantinib is the recommended first-line treatment for patients with metastatic papillary carcinoma. Cystic tumours should be classified according to the Bosniak classification. Surgical removal should be proposed as a priority for Bosniak III and IV lesions. It is recommended that patient monitoring be adapted to the aggressiveness of the tumour. CONCLUSION: These updated recommendations are a reference that will allow French and French-speaking practitioners to improve kidney cancer management.

Management of long ureteral stenosis: Alternatives to indwelling ureteral stents.

OBJECTIF: Evaluate kidney autotransplantation (KAT) and ileal ureter substitution (IUS) practice and outcome as alternatives to indwelling ureteral stents for the management of long ureteral stenosis (US). MATERIAL: We included all patients treated for US with KAT or IUS in 5 French university urology centers between 2010 and 2018. We excluded US due to urothelial carcinoma. Primary endpoint was the preservation of ipsilateral kidney and renal function without any urinary diversion. RESULTS: 22 patients were treated with KAT (n=8, 36.4%) and IUS (n=14, 63.6%). Mean US length was 4.6cm and 6cm (P=0.52) in KAT and IUS groups respectively. US etiologies were lithiasis, iatrogenic, retroperitoneal fibrosis or extrinsic compression. US level was varied. The surgery was described as difficult because of peritoneal adhesions or major peri-ureteral fibrosis. Mean operating time and hospital stay were 336 and 346minutes (P=0.87) and 8 and 15 days respectively (P=0.001). Postoperative complications were mostly Clavien ≤2 (n=17, 77.3%). Revision surgery was required in the KAT group in 3 cases (37.5%), for textiles, renal vein thrombosis and anastomotic leak, none in the IUS group. The mean follow-up was 15.7 months. All but one (in the KAT group) ipsilateral kidneys were preserved, without renal function impairment (Δcreat +2.1 vs. +2.4µmol/l respectively, P=0.67), nor urinary diversion. CONCLUSION: KAT and IUS are safe alternatives whose indication depends on surgeons expertise. Our study pointed out the scarcity of this practice suggesting the need to refer patients to expert centers. LEVEL OF EVIDENCE: 3.

Nephron sparing surgery in tumours greater than 7cm.

INTRODUCTION: Partial nephrectomy (PN) is the gold standard treatment for renal cell carcinomas under 4cm. No robust data exists to recommend PN for tumours>7cm (cT2). The objective of this work is to evaluate the results of PN for cT2 tumours. PATIENTS AND METHODS: All patients who underwent PN or radical nephrectomy (RN) for cT2 tumours between 2000 and 2013 at our institution have been included. Patient demographics, postoperative data including renal function, morbidity, mortality and oncologic outcomes were reviewed retrospectively and compared using χ2 test, Mann-Whitney test, Kaplan-Meier method and log rank test. RESULTS: We included 130 patients, 49 (38%) in the PN group and 81 (62%) in the RN group, with a median follow-up of 42 months [19-69]. Variation of postoperative renal function at day 5 and last recorded value was significantly different between the groups (P=0.03 and P<0.001). The PN group had a significantly higher complication rate as compared with RN group (37% versus 14%, P=0.002). There were no significant differences between the two groups for overall, recurrence free and specific survival (P=0.55, P=0.55, P=0.24, respectively). In univariate analysis, the type of surgery (PN versus RN) was not associated with a significant difference of oncologic outcome (margins, survival). CONCLUSION: PN can be offered for cT2 tumours with oncological outcomes similar to RN. Despite an increased morbidity, it remains acceptable with the demonstrated advantage of preservation of renal function. LEVEL OF EVIDENCE: 4.

Predictors of high level of burden and distress in caregivers of demented patients: results of an Italian multicenter study.

BACKGROUND: Considerable suffering is experienced by carers of patients with dementia. Most existing studies do not consider the coexistence of subjective and objective aspects that cause, interacting to each other, this suffering. OBJECTIVES: In this study we: (1) define the high-risk group of caregivers on the bases of the scores obtained on the four scales evaluating burden, distress, depression and anxiety (BDDA) taken into account simultaneously and (2) evaluate risk factors related to the high level of BDDA. SUBJECTS AND METHODS: 419 elderly outpatients with dementia and their caregivers were enrolled. Patients were evaluated for their cognitive, neuropsychological and functional impairment and for comorbidity. Caregivers were evaluated with four scales for the assessment of burden, distress related to neuropsychological disturbances, depression and anxiety. Cluster analysis was used to identify the group with the High level of BDDA (HBDDA). RESULTS: By multiple logistic analysis, disability, specific behavioural disturbances of the patients as well as caregiver's age, type of relationship and living in the south of Italy were observed to be a major risk factor for HBDDA. CONCLUSION: The targeted use of scales specifically assessing BDDA of the caregiver and the identification of particular patient and caregiver characteristics are able to allow a precise and early definition of caregivers at high risk of burden and distress. This might be helpful in planning the correct social/clinical/rehabilitative approach.

[Pharmacologic therapy in the elderly]. / Terapia farmacologica nell'anziano.

The pharmacological treatment in the older people should be carefully considered: older patients are at the same time the greatest consumers of drugs and the population with the greatest risk of adverse drug reactions (ADR). The ADR are in the old patient more frequent and serious for the greater number of concurrent drugs. The incorrect drug's use consists in prescribing too much or too little, for an excessive period, without a defined diagnosis and an appropriate selection of the better compound. Moreover, beneficial drugs may be frequent underused, some chronic conditions do not receive adequate pharmacologic treatment, and an ADR may be misinterpreted as a new pathological condition that requires a new prescription. The unusual presentation of many diseases in elderly play a role to complicate the clinical process necessary to optimising the drug treatment. About the risks and the benefits of pharmacological treatment, adequate data in older patients are in general lacking for the poor inclusion in clinical trials of the elderly subjects, especially frail persons.

Amyloid precursor protein in platelets of patients with Alzheimer disease: effect of acetylcholinesterase inhibitor treatment.

BACKGROUND: Amyloid precursor protein (APP) forms with apparent molecular weights of 130, 110, and 106 kd are present in human platelets. It has been demonstrated that Alzheimer disease (AD) is specifically associated with a decreased APP forms ratio in platelets. OBJECTIVE: To investigate whether acetylcholinesterase (AChE) inhibitor treatment modifies the ratio of platelet APP forms in patients with AD. PATIENTS AND METHODS: From a large sample of patients with probable AD, 30 with mild to moderate AD were selected. Each patient underwent a clinical evaluation including the Mini-Mental State Examination (MMSE) and platelet APP forms analysis at baseline and after 30 days. During this interval, 20 of 30 patients with AD were treated with donepezil hydrochloride (5 mg/d), a piperidine phosphate-based cholinesterase inhibitor. Platelets were subjected to Western blot analysis using monoclonal antibody (22C11). The ratio between the immunoreactivity of the higher-molecular-weight APP form (130 kd) and the lower forms (106 and 110 kd) was measured. RESULTS: All patients taking donepezil completed the 30 days of treatment without adverse effects. The platelet APP forms ratio at baseline did not differ between the 2 AD groups (mean +/- SD optical density ratio: untreated AD, 0.47 +/- 0.12; treated AD, 0.38 +/- 0.18), whereas a significant difference was found at follow-up (mean +/- SD optical density ratio: untreated AD, 0.45 +/- 0.17; treated AD, 0.77 +/- 0.29; P<.001). A significant improvement in MMSE scores in treated AD patients was observed from baseline (16.9 +/- 3.8) to 30 days (18.9 +/- 4.42) (P<.009, 30 days vs baseline), but no significant correlation was found in treated AD patients between MMSE score improvement and APP forms/ratio increase (P =.09). CONCLUSIONS: Administration of AChE inhibitors increases the ratio of APP forms in platelets of patients with AD, suggesting a potential effect of AChE inhibitors on APP trafficking or processing in a peripheral cell.

Amyloid precursor protein in platelets: a peripheral marker for the diagnosis of sporadic AD.

BACKGROUND: An altered pattern of amyloid precursor protein (APP) forms consisting in a reduced ratio between the upper (130 kDa) and the lower (106 to 110 kDa) immunoreactivity bands has been described in platelets of patients with AD. OBJECTIVE: To evaluate the sensitivity and the specificity of platelet APP forms' ratio (APPr) as a marker for AD. METHODS: Eighty-five patients with probable AD and 95 control subjects (CON), including healthy individuals and neurologic patients, entered the study. Platelet APPr was evaluated by means of Western Blot analysis and immunostaining in the whole platelet homogenate, and calculated by the ratio between the optical density (OD) of the upper (130 kDa) and the lower (106 to 110 kDa) APP immunoreactive bands. RESULTS: Mean APPr levels were decreased in AD patients (mean OD +/- SD = 0.35 +/- 0.18) compared with the CON group (mean OD +/- SD = 0.92 +/- 0.38) (DF 1, 178, p < 0.0001). Accuracy levels measured by Receiver Operating Curve analysis showed that a cut-off level of 0.57 resulted in a sensitivity of 88.2% and a specificity of 89.4%, with an area under the curve of 0.945. APPr levels were significantly associated with disease severity (mild AD versus moderate AD: p < 0.0001; moderate AD versus severe AD: p < 0.05). CONCLUSION: Platelet APPr allowed to differentiate AD from normal aging and other dementing disorders with high sensitivity and specificity. These findings suggest that platelet APPr may be of help as an adjunctive diagnostic tool in clinical practice.

Neuropsychological assessment of the severely impaired elderly patient: validation of the Italian short version of the Severe Impairment Battery (SIB). Gruppo di Studio sull'Invecchiamento Cerebrale della Società Italiana di Gerontologia e Geriatria.

One hundred and sixty-nine severely demented patients were tested in a multicenter study with the short version of the Severe Impairment Battery which was translated into Italian with the purpose of adapting and validating it for an Italian population. Patients were enrolled in Italian geriatric centers participating in the Study Group on Aging Brain of the Italian Society of Gerontology and Geriatrics. Following thorough clinical and instrumental examinations, they were evaluated with the Mini Mental State Examination, the Clinical Dementia Rating, the Severe Impairment Battery (SIB), the Gottfries-Bråne-Steen Rating Scale for Dementia, the Activity of Daily Living index, and the Bedford Alzheimer Nursing Severity scale (BANS.s). The inter-rater reliability of the SIB was highly significant for the total score and its subtests; test-retest reliability showed the same significance in all items. Also concurrent validity, performed comparing the total SIB score with the total BANS.s score, was significant. The short Italian version of the SIB proved to be a very reliable tool for the evaluation of severely demented patients; it has the advantage of being easy to administer, it evaluates more cognitive domains that, are typically assessed in dementia, and has a wide enough range of scores to detect even small differences in the examined abilities.

Mortality studies in the clarification of gene-environment interactions.

In this paper we review some theories about the process of senescence and death, in particular the theory of accumulation of mutations and the theory of antagonistic pleiotropism. These theories are reviewed in the light of existing scientific evidence, with particular reference to that which points to the possible role of interactions between genes and environment. We conclude that mortality studies, particularly on migrant populations may be an important tool for clarifying this major issue.

Cytokine antagonists in aged subjects and their relation with cellular immunity.

Host responses to infectious and inflammatory stimuli are altered with aging. Because cytokines and their antagonists are significant factors in these host responses, the present research on aged subjects was designed to investigate plasma concentrations of the cytokines interleukin 1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF alpha) and those of their antagonists IL-1 receptor antagonist (IL-1ra) and soluble TNF receptor (sTNFr). For this research, 122 apparently healthy aged subjects (79.6 +/- 5.8 yr), 39 aged individuals with documented urinary tract infections (UTIs) (81.6 +/- 6.3 yr), and 100 young controls (39.32 +/- 11.2 yr) were included. Plasma IL-1 beta, TNF alpha, IL-1ra, sTNFr (55 kDa), and neopterin were measured using enzyme-linked immunosorbent assay techniques. In subsets of normal aged subjects and UTI patients, we investigated relations between plasma concentrations of cytokine antagonists and IL-2 production by phytohemagglutinin-stimulated peripheral blood mononuclear cells. The results show that plasma concentrations of both IL-1ra and sTNFr were greater in healthy aged subjects than in young controls. Plasma neopterin, a product of activated monocytes/macrophages, was likewise elevated in the aged. IL-1 and TNF were not detectable in the majority of plasma samples. There was a positive correlation between neopterin concentration and both IL-1ra and sTNFr. There was a significant negative correlation between plasma IL-1ra and IL-2 production by phytohemagglutinin-stimulated peripheral blood mononuclear cell in healthy aged subjects. IL-1ra and sTNFr concentrations were significantly greater in patients with UTI than in the healthy aged subjects. In UTI patients IL-2 production in vitro was lower than in healthy subjects, but there was no significant correlation with IL-1ra in plasma. Therefore, plasma concentrations of cytokine antagonists are increased in plasma of apparently healthy aged subjects. Elevated concentrations of neopterin suggest that this increase can be traced to monocyte activation. The negative correlation between plasma IL-1ra and IL-2 production in vitro suggests that enhancement of this cytokine antagonist can contribute to immunodepression of aging. We propose that unapparent infections in aged subjects cause monocyte activation and release of cytokine antagonists. These cytokine antagonists reduce IL-2 production and the capability of T cells to proliferate, thereby inhibiting responses in the elderly.

Immunopharmacological activity of cefodizime in young and elderly subjects: in vitro and ex vivo studies.

The biological response modifying activities of cefodizime (CDZ), a new third-generation cephalosporin, were investigated in vitro and ex vivo. In vitro investigations using cells isolated from the blood of young healthy donors showed no stimulating activity of CDZ on peripheral blood lymphocytes, natural killer cell activity, IL-1 production by adherent mononuclear cells, PMN chemiluminescence or PMN chemotaxis. A slight but statistically insignificant increase in PMN phagocytosis and phagocytic index was observed in the same population. IL-1 production was increased in three subjects with low resting state values. In a controlled ex vivo study, 20 healthy elderly subjects selected on the basis of depressed phagocytic function were treated with CDZ 1 g i.m. b.i.d. or placebo for eight days. PMN function was determined at baseline and on the day after the last dose. In the CDZ group a significant increase in both phagocytosis and phagocytic index was found, while there were no changes in the placebo group. In conclusion, CDZ restored depressed PMN phagocytic function in a population of elderly subjects. Patients with impaired PMN function who require antibiotic treatment may benefit from this activity of CDZ.

Immunological features of nonhealing midline granuloma.

A 60-year-old man affected by nonhealing midline granuloma (NHmG) is described. The histopathological features, the clinical course and the radiosensitivity of the lesion clearly differentiate this pathological condition from malignant lymphomas and from Wegener's granulomatosis (WG). The presence of antinuclear antibodies with an antinucleolar pattern in a subject bearing HLA-B8 suggests the involvement of autoimmune phenomena and a close relation between NHmG and WG.

Extraction and characterization of circulating plasma DNA from patients with pulmonary embolism.

Circulating DNA has been extracted from plasma of 6 patients with pulmonary embolism; it appears of low molecular weight (about 400 base pairs) and of uniform size; its staining sensitivity to ethidium bromide suggests it is mainly double stranded. DNA circulates linked with proteins.

MLC-specific suppressor T lymphocytes in man. I. Their induction in vitro by soluble HLA-DR antigens.

Human T lymphocytes precultured for 36 hr in the presence of soluble HLA-DR antigens suppress the MLR response of autologous peripheral blood lymphocytes to allogeneic stimulating cells. The suppression is DR antigen-specific in that it appears that the MLR stimulating cell donor and the soluble suppressor-inducing antigen must share DR specificities. The soluble DR antigens were fractionated from the sera of normal donors using QAE-Sephadex chromatography and CNBr-activated Sepharose immunoadsorption. Similarly prepared HLA-A and -B antigens failed to induce suppressive activity. The suppressive activity of DR-antigen cultured T cells is resistant to mitomycin C treatment and, further, the antigen specificity is maintained with or without mitomycin C treatment. The kinetics of suppressor cell induction as well as the kinetics of suppression in the test MLR cultures are presented. The implications of these results are discussed.
