RESUMEN
BACKGROUND: Basophils, eosinophils and monocytes may be involved in BCG-induced immune responses and be associated with outcomes of bladder cancer patients receiving intravesical BCG. Our objective was to explore the association of baseline counts of basophils, eosinophils and monocytes with outcomes of patients with high-grade T1 bladder cancer receiving a standard course of intravesical BCG. METHODS: We retrospectively reviewed medical records of patients with primary T1 HG/G3 bladder cancer. After re-TURBT, patients were treated with a 6-week course of intravesical BCG induction followed by intravesical BCG every week for 3 weeks given at 3, 6, 12, 18, 24, 30 and 36 months from initiation of therapy The analysis of potential risk factors for recurrence, muscle invasion and cancer-specific and overall survival was performed using univariable Cox regression models. Those factors that presented, at univariate analysis, an association with the event at a liberal p < 0.1, have been selected for the development of a multivariable model. RESULTS: A total of 1045 patients with primary T1 HG/G3 were included. A total of 678 (64.9%) recurrences, 303 (29.0%) progressions and 150 (14.3%) deaths were observed during follow-up. Multivariate analysis showed that logarithmic transformation of basophils count was associated with a 30% increment in the hazard of recurrence per unit increase of logarithmic basophils count (HR 1.30; 95% confidence interval 1.09-1.54; p = 0.0026). Basophil count modeled by quartiles was also significantly associated with time to recurrence [second vs. lower quartile HR 1.42 (1.12-1.79); p = 0.003, third vs. lower quartile HR 1.26 (1.01-1.57); p = 0.041; upper vs. lower quartile HR 1.36 (1.1-1.68); p = 0.005]. The limitations of a retrospective study are applicable. CONCLUSION: Baseline basophil count may predict recurrence in BCG-treated HG/G3 T1 bladder cancer patients. External validation is warranted.

BACKGROUND AND PURPOSE: The aim of our study was to describe, by a case-control and cross-sectional design, the correlation between clinical impairment and age in Charcot-Marie-Tooth type 1A (CMT1A) patients. METHODS: Seventy CMT1A patients and 70 sex- and age-matched healthy controls were enrolled. Motor performance was assessed through the 10-m walk test, the 6-min walk test and the 9-hole peg test of the dominant and non-dominant side, and muscle strength was measured by using the Medical Research Council score. In the CMT1A group, disability and quality of life were evaluated using the Charcot-Marie-Tooth Neuropathy Score (CMTNS) and the Short Form 36 (SF-36) questionnaire. Cross-sectional relationships between age and all clinical measures were analyzed and differences in the slopes between cases and controls were calculated. The occurrence of a structural change in the age-related progression of clinical measures was explored. RESULTS: The deterioration of motor performance correlated with age in both groups with a greater slope in CMT1A patients than controls. The deterioration of CMTNS and SF-36 correlated with age in the CMT1A group. The deterioration of all clinical measures with the exception of the SF-36 questionnaire showed a structural change at the 50th year of age. The rate of deterioration was no different between patients and controls until 50 years of age, whereupon it became significantly greater in CMT1A patients. CONCLUSION: Our study supports that the disease progression in CMT1A patients is an age-related process and the 50th year of age represents a critical moment after which the clinical decline becomes faster.

Lower urinary tract dysfunctions (LUTDs) are commonly reported in multiple sclerosis (MS) patients and are mainly related to neurogenic overactive bladder (OAB). The aim of this observational study was to assess the effect of a tetrahydrocannabinol-cannabidiol (THC/CBD) oromucosal spray on resistant OAB by means of clinical and instrumental tools. Twenty-one MS patients were screened, and 15 cases have been evaluated. They underwent a specific clinical assessment (overactive bladder symptom score, OABSS) and a urodynamic assessment evaluating the maximal cystometric capacity (CCmax), bladder compliance (Qmax), maximum detrusor pressure (Pdet max), detrusor pressure at the first desire (Pdet first), bladder volume at the first desire (BVFD), leakage volume (LV), and post-void residual volume (PVR), before and after 4 weeks of THC/CBD administration. A complete neurological evaluation, including the assessment of their spasticity using the Modified Ashworth Scale (MAS) and the spasticity 0-10 numerical rating scale (NRS), was performed at the same times. Mobility was evaluated through the 25-ft walking-time test (T25-WT). The THC/CBD treatment successfully reduced the OAB symptoms (p = 0.001). Regarding the urodynamic findings after the end of treatment, PVR was significantly reduced (p = 0.016). Regarding the urodynamic findings after the end of treatment, PVR was significantly reduced (p = 0.016), while BVFD and CCmax were increased although the difference was not statistically significant. THC/CBD oromucosal spray has shown to be effective in improving overactive bladder symptoms in MS patients demonstrating a favorable impact on detrusor overactivity.

BACKGROUND: Although guidelines do not recommend computerised tomography (CT), positron emission tomography (PET) or magnetic resonance imaging (MRI) for the staging or follow-up of asymptomatic patients with non-metastatic breast cancer, they are often requested in routine clinical practice. The aim of this study was to determine the staging and follow-up patterns, and relative costs in a large population of breast cancer patients living and treated in a Southern Italian region. METHODS: We analysed the clinical computerised information recorded by 567 primary-care physicians assisting about 650 000 inhabitants in the Campania region. Patients with non-metastatic breast cancer were identified and divided into calendar years from 2001 to 2010. The number of diagnostic tests prescribed per 100 patients (N/Pts) and the mean cost per patient was determined 3 months before diagnosis and up to 1 year after diagnosis. Costs are expressed in constant 2011 euros. RESULTS: We identified 4680 newly diagnosed cases of asymptomatic non-metastatic breast cancer. N/Pts increased significantly (P<0.0001) from 2001 to 2010. The mean number of prescribed mammograms, bone scans, abdominal ultrasound and chest X-rays ('routine tests'), and costs was unchanged. However, the number of CT, PET scans and MRI ('new tests')prescriptions almost quadrupled and the mean cost per patient related to these procedures significantly increased from [euro ]357 in 2001 to [euro ]830 in 2010 (P<0.0001). CONCLUSIONS: New test prescriptions and relative costs significantly and steadily increased throughout the study period. At present there is no evidence that the delivery of new tests to asymptomatic patients improves breast cancer outcome. Well-designed clinical trials are urgently needed to shed light on the impact of these tests on clinical outcome and overall survival.

BACKGROUND AND AIM: The aim of this study was to compare the use of insulin glargine and intermediate/long-acting human insulin (HI) in relation to the incidence of complications in diabetic patients. METHODS AND RESULTS: A population-based cohort study was conducted using administrative data from four local health authorities in the Abruzzo Region (900,000 inhabitants). Diabetic patients without macrovascular diseases and treated with either intermediate/long-acting HI or glargine were followed for 3-years; the incidence of diabetic (macrovascular, microvascular and metabolic) complications was ascertained by hospital discharge claims and estimated using Cox proportional hazard models. Propensity score (PS) matching was also used to adjust for significant differences in the baseline characteristics between the two groups. RESULTS: Overall, 1921 diabetic patients were included: 744 intermediate/long-acting HI and 1177 glargine users. During the 3-year follow-up, 209 (28.1%) incident events of any diabetic complication occurred in the intermediate/long-acting HI and 159 (13.5%) in the glargine group. After adjustment for covariates, glargine users had an HR (95% CI) of 0.57 (0.44-0.74) for any diabetic complication and HRs of 0.61 (0.44-0.84), 0.58 (0.33-1.04) and 0.35 (0.18-0.70) for macrovascular, microvascular and metabolic complications, respectively, compared to intermediate/long-acting HI users. PS analyses supported these findings. CONCLUSIONS: The use of glargine is associated with a lower risk of macrovascular complications compared with traditional basal insulins. However, limitations inherent to the study design including the short length of observation and the lack of data on metabolic control or diabetes duration, do not allow us to consider this association as a proof of causality.

The efficacy of Lacticaseibacillus rhamonosus GG (LGG) for the treatment of children with acute gastroenteritis has been debated based on most recent evidence. Previous evidence demonstrated that LGG mainly benefits children with Rotavirus infection compared to other aetiologies. However, Rotavirus immunisation (RVI) has been implemented worldwide since 2006. We aimed to investigate whether the efficacy of LGG in children with gastroenteritis vary according to RVI status. The MEDLINE, Embase and Cochrane library databases were searched for relevant randomised controlled trials (RCT) up to April 2022. The duration of diarrhoea and episodes lasting >48 h were considered as primary outcomes. The date of vaccine introduction and RVI coverage were reviewed for all countries where trials were conducted. Among the 15 RCTs included in the analysis (n=3,465), only 5 showed a low risk of bias. In RCT conducted before the introduction of RVI (n=2,932), LGG was effective in reducing the duration of diarrhoea compared with placebo or standard care (Median -23.80 h, 95% confidence interval (CI) -36.59 to -11.02]). Only 2 RCTs (n=1,072) reported data of populations partially immunised against Rotavirus with an overall coverage of 44 and 67%, respectively. In this population, LGG showed no efficacy in reducing the duration of diarrhoea (Median -5.34, 95%CI -12.9 to 2.22). Similarly, LGG reduced the risk of diarrhoea lasting >48 h in children not immunised against Rotavirus (RR 0.73, 95%CI 0.54-0.99), but not in population partially immunised (RR 0.98, 95%CI 0.87 to 1.11). The implementation of RVI might affect the efficacy of LGG modifying local epidemiology and susceptibility of the target population to selected probiotics.

BACKGROUND: We evaluated the efficacy and safety of the nontaxane microtubule dynamics inhibitor eribulin plus the humanized anti-VEGF monoclonal antibody bevacizumab in a novel second-line chemotherapy scheme in HER2-negative metastatic breast cancer (MBC) patients progressing after first-line paclitaxel and bevacizumab. PATIENTS AND METHODS: This is a multicenter, single-arm, Simon's two-stage, phase II study. The primary endpoint was the overall response rate, considered as the sum of partial and complete response based on the best overall response rate (BORR). The secondary endpoints were progression-free survival (PFS), overall survival (OS), and clinical benefit rate. RESULTS: A total of 58 of the 61 patients enrolled in the study were evaluable for efficacy. The BORR was 24.6% (95% CI 14.5-37.3). The clinical benefit rate was 32.8% (95% CI 21.3-46.0). The median PFS was 6.2 months (95% CI 4.0-7.8), and median OS was 14.8 months (95% CI 12.6-22.8). Overall, adverse events (AEs) were clinically manageable and the most common AEs were fatigue, paresthesia, and neutropenia. Quality of life was well preserved in most patients. CONCLUSIONS: The results of this study suggest that second-line therapy with bevacizumab in combination with eribulin has a meaningful clinical activity and may represent a potential therapeutic option for patients with HER2-negative MBC.

PURPOSE: To evaluate the presence of strabismus in patients with developmental cataract rendered pseudophakic and how this influences their visual acuity. METHODS: A retrospective study was carried out on 113 patients with developmental cataract who came under the authors' observation at the outpatient department of the Pediatric Ophthalmology Unit of the University of Federico II of Naples from 1990 to 2005. All patients were followed up for a long period (mean 62 months, range 36-144 months). Age at diagnosis, sex, laterality, age at cataract extraction, morphology, and cataract density were all considered as possible factors associated with strabismus. Visual acuity and ocular motility before and after cataract extraction surgery were especially noted. Statistical evaluation was performed using t-test, Chi-square test, and Fisher exact test. RESULTS: Out of the 113 patients a total of 181 eyes were affected: 68 patients (60%) presented bilateral cataract, 45 patients (40%) monolateral cataract. Strabismus was present in 39 patients (34%) before cataract surgery. Age at cataract diagnosis, age at surgery, sex, and cataract morphology were not found to be statistically associated with strabismus. However, laterality was found to be statistically associated with the onset of strabismus. Cataract density was found to be statistically associated with poor vision. Patients with strabismus presented a non statistically significant lower visual acuity. CONCLUSIONS: Strabismus has a greater incidence in developmental cataract compared to the general population, and can influence visual acuity, especially in monolateral and total cataracts. Intraocular lens implants produced satisfactory visual rehabilitation.

PURPOSE: To evaluate visual outcomes, eye movement abnormalities, and postoperative complications after secondary posterior chamber intraocular lens (IOL) implantation in aphakic children who had initial LAC correction. METHODS: A retrospective study was carried out on 53 patients (94 eyes). Following aphakic surgery and LAC correction the patients received secondary IOL implantation in the posterior chamber. Special attention was paid to factors that may have influenced their visual outcomes, such as eye movement abnormalities, cataract unilaterality, and cataract density. RESULTS: No association was found between age at surgery and the onset of strabismus (p=0.611) or with visual acuity (p=0.086). However, unilaterality and total cataract density were found to have a negative association with poor vision (p<0.001). Strabismus and nystagmus were found to have a statistically significant negative association with visual acuity (p=0.002). Posterior capsule opacification occurred in six eyes of five patients following cataract extraction; IOL dislocation occurred in four eyes after IOL intraocular implantation, and secondary glaucoma occurred in one eye. CONCLUSIONS: IOL implantation before 12 months of age may be useful in unilateral cataract; in bilateral cataract, simultaneous surgical aphakia, LAC correction, and then IOL implantation at 2.5-3 years of age, together with anti-amblyopic therapy when strabismus or asymmetric cataract density occur, are efficient methods to obtain visual recovery. Extraocular muscle surgery may be required to correct strabismus.

The patient-physician relationship can be conceived as a process of structuring an ill-structured emotional-cognitive problem. So, new methods should be developed in order to capture the relations among emotions and cognitions, and physicians should be educated to recognize the influence of emotions on medical decision-making. The paper describes GRASP, an e-learning application based upon the assumption that cognitions and emotions are dual concepts. The results of a blended e-learning experiment are shown. The students were confronted with a role-playing based illness narrative. Their observations were segmented into information units, and uploaded on the e-learning system DVLN. The set of information units was then transformed into a bipartite graph, and analysed by means of STRUCTURE, an application aimed at grasping the structure of the relations among a set of "objects". The results were compared with Correspondence Analysis. The implications for medical education, medical reasoning, and medical record design are discussed.

BACKGROUND: Infant colic (IC) is a prevalent physiological event of infants, which can disrupt the child's home environment. We aimed to investigate the effectiveness of a mixture of Matricariae chamomilla L., Melissa officinalis L. and tyndallized Lactobacillus acidophilus (HA122) compared with Lactobacillus reuteri DSM 17938 and with simethicone for the treatment of IC. METHODS: A multicenter randomized comparative study was conducted in infants with colic, according to Rome III criteria, who were randomly assigned to receive M. chamomilla L., M. officinalis L. and tyndallized L. acidophilus (HA122) (Colimil® Plus® ; Milte Italia Spa, Milan, Italy) (Group A), L. reuteri DSM 17938 (Group B) and simethicone (Group C). Treatment was given to subjects for 28 days. KEY RESULTS: One-hundred and seventy-six patients completed the study. Mean daily crying time at day 28 was significantly lower in group A (-44, 95% CI: -58 to -30, P<.001) and group B (-35, 95% CI: -49 to -20, P<.001) when compared to group C. No significant difference was observed between Group A and Group B (mean difference: -9 minutes, 95% CI -23 to +5, P=.205). At day 28, 39 of 57 (68.4%) of infants in Group C responded to the treatment compared with 57 out of 60 patients (95%) of Group A and 51 out of 59 (86.4%) of Group B (P<.001). CONCLUSIONS: This study suggests that administration of M. chamomilla L., M. officinalis L. and tyndallized L. acidophilus (HA122) and L. reuteri DSM 17938 are significantly more effective than simethicone in IC. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov: NCT02708238.

Hyperhomocysteinemia is considered a risk factor in arterial and venous thrombosis. The mechanism by which homocysteine (HCy) supports atherothrombosis is still unknown and may be multifactorial. Earlier in vitro studies demonstrated that HCy induced arachidonic acid release and increased thromboxane B2 (TXB2) formation. In this work, we found that HCy stimulated the rapid and sustained phosphorylation of platelet p38 mitogen-activated protein kinase (p38 MAPK). The effect was time- and dose-dependent. The HCy effect on p38 MAPK phosphorylation was prevented by N-acetyl-L-cysteine and iloprost and was partially inhibited by nordihydroguaiaretic acid. Moreover, the incubation of platelets with HCy led to the phosphorylation of cytosolic phospholipase A2 (cPLA2). In addition HCy promoted cPLA2 activation, assessed as arachidonic acid release. The cPLA2 phosphorylation and activation were both impaired by the inhibition of p38 MAPK through SB203580. This effect was not complete, reaching at the most the 50% of the total. In FURA 2-loaded platelets, HCy induced a dose-dependent intracellular calcium rise suggesting that the calcium elevation promoted by HCy could participate in the cPLA2 activation, leading to arachidonic acid release and TXB2 formation. In conclusion, our data provide insight into the mechanisms of platelet activation induced by HCy, suggesting that the p38 MAPK/cPLA2 pathway could play a relevant role in platelet hyperactivity described in hyperhomocysteinemia.

BACKGROUND: Nosocomial infections are a major public health issue and preventative strategies using probiotics and micronutrients are being evaluated. AIM: To investigate the efficacy of a mixture of Lactobacillus GG and micronutrients in preventing nosocomial infections in children. METHODS: A randomised, double-blind, placebo-controlled trial was conducted in hospitalised children. Children (6 months to 5 years of age) received Lactobacillus GG (6 × 10(9) CFU/day) together with vitamins B and C and zinc or placebo, for 15 days, starting on the first day of hospitalisation. The incidence of gastrointestinal and respiratory nosocomial infections after discharge was determined by follow-up telephone call at 7 days. After 3 months, another telephone call estimated the incidence of further infections during follow-up. RESULTS: Ninety children completed the follow-up. Of 19/90 children with a nosocomial infection (20%), 4/45 children (9%) were in the treatment group and 15/45 (33%) in the placebo group (P = 0.016). Specifically, 2/45 (4%) children in the treatment group vs. 11/45 (24%) children in the placebo group (P = 0.007) presented with diarrhoea. The duration of hospitalisation was significantly shorter in the treatment group (3.9 days ± 1.7 vs. 4.9 ± 1.2; P = 0.003). At the follow-up, a total of 11/45 (24.4%) children in the treatment group had at least one episode of infection compared to 22/45 (48.9%) in the placebo group (P = 0.016). CONCLUSION: A mixture containing Lactobacillus GG and micronutrients may reduce the incidence of nosocomial infections, supporting the hypothesis that this may represent a valid strategy to prevent nosocomial infections.

OBJECTIVES: To assess and compare the ovarian reserve in patients with different-sized endometriomas undergoing cystectomy or ablative surgery in order to determine the best surgical approach to safeguard healthy ovarian tissue. STUDY DESIGN: Prospective randomized study on 48 patients with unilateral single ovarian endometriomas. Patients were allocated into two groups based on endometrioma size: <5cm (n=26, Group A, small endometriomas) and ≥5cm (n=22, Group B, large endometriomas). Each group was randomized to coagulation or excision treatment (1:1 ratio) before the procedure. Anti-Müllerian hormone (AMH) levels were evaluated before surgery and 3 months after surgery. RESULTS: Both ablation and excision resulted in a significant reduction in AMH level regardless of endometrioma size. A significant interaction effect was observed between endometrioma size and type of surgical technique (analysis of covariance p for interaction=0.039): in Group A, no significant difference was found between the two surgical techniques (-17.6±4.7% vs -18.2±10.6%), whereas in Group B, the excision group showed a significantly greater percentage decrease in AMH level compared with the ablation group (-24.1±9.3% vs -14.8±6.7%, p=0.011). CONCLUSIONS: Both ablative and excision treatment of endometriomas have a negative effect on ovarian function. Endometrioma size is associated with the magnitude of ovarian reserve damage following excision treatment, but in the case of ablative treatment, the decrease in AMH serum level is independent of the size of the cyst. In surgical treatment of large endometriomas, the decrease in AMH level is more consistent and much more severe following cystectomy than ablation.

PURPOSE: Groin hernia is one of the most common disease requiring surgical intervention (8-10% of the male population). Nowadays, the application of prosthetic materials (mesh) is the technique most widely used in hernia repair. Although they are simple and rapid to perform, and lower the risk of recurrence, these techniques may lead to complications. The aim of the present study is to assess the incidence and degree of chronic pain, as well as the impairment in daily life, in two procedures: (1) the "Lichtenstein technique" with polypropylene mesh fixed with non-absorbable suture, and (2) the "sutureless" technique carried out by using a partially absorbable mesh (light-weight mesh) fastened with fibrin glue. METHODS: This was a study conducted over a period of 3 years from July 2006 to July 2009. A total of 148 consecutive male patients suffering from groin hernia were divided randomly into two groups: (1) Group A: patients operated with "sutureless" technique with partially absorbable mesh and plug fastened with 1 ml haemostatic sealant; (2) Group B: patients operated with Lichtenstein technique using non-absorbable mesh and plug anchored with polypropylene suture. Follow-up took place after 7 days, and 1, 6 and 12 months and consisted of examining and questioning patients about chronic pain as well as the amount of time required to return to their normal daily activities. RESULTS: No major complications or mortality were observed in either group. In group A there was a faster return to work and daily life activities. Six patients (7.8%) in group B suffered from chronic pain, whereas no patient in group A demonstrated this feature. CONCLUSIONS: Our experience shows that the combined use of light-weight mesh and fibrin glue gives significantly better results in terms of postoperative pain and return to daily life.

The rapid pull-through (RPT) technique during esophageal manometry helps to identify various pressure profiles of hiatal hernia (HH), based on the presence of two high pressure zones: the diaphragmatic crura (DC) and the lower esophageal sphincter (LES). Our aim was to correlate different HH profiles with frequency of reflux episodes in patients with gastroesophageal reflux disease (GERD). Seventy-eight patients with GERD and HH underwent esophageal manometry with RPT and were grouped according to the prevalent pressure profile of HH. Twenty-four-hour pH-metry served to quantify traditional (TR) and nontraditional refluxes (drop of 1 pH unit with pH > 4 or pH < 4 and time < 5 sec) (NTR) during total, upright, and recumbent periods. The group with a prevalent "flat" HH profile, representing LES and DC impairment, had significantly more TRs in total time of reflux (P < 0.01) and in recumbent and upright periods (P < 0.05) compared to the group with a prevalence of the two pressure peaks, corresponding to LES and DC efficiency. However, the group with the flat profile had significantly more NTRs + TRs than the group with pressure peaks in total time (P < 0.01) and recumbent position (P < 0.001) but not in the upright position. Hiatal hernia predisposes to GERD, but only the associated impairment of the LES and diaphragmatic crura pressures represents a condition of high risk for gastroesophageal reflux events.
