The long-term effect on surgery-free survival of biological compared to conventional therapy in Crohn's disease in real world-data: a retrospective study.

BACKGROUND: The introduction of biological drugs has led to great expectations and growing optimism in the possibility that this new therapeutic strategy could favourably change the natural history of Inflammatory Bowel Disease (IBD) and, in particular, that it could lead to a significant reduction in surgery in the short and long term. This study aims to assess the impact of biological versus conventional therapy on surgery-free survival time (from the diagnosis to the first bowel resection) and on the overall risk of surgery in patients with Crohn's disease (CD) who were never with the surgical option. METHODS: This is a retrospective, double-arm study including CD patients treated with either biological or conventional therapy (mesalamine, immunomodulators, antibiotics, or steroids). All CD patients admitted at the GI Unit of the S. Salvatore Hospital (L'Aquila. Italy) and treated with biological therapy since 1998 were included in the biological arm. Data concerning the CD patients receiving a conventional therapy were retrospectively collected from our database. These patients were divided into a pre-1998 and post-1998 group. Our primary outcome was the evaluation of the surgery-free survival since CD diagnosis to the first bowel resection. Surgery-free time and event incidence rates were calculated and compared among all groups, both in the original population and in the propensity-matched population. RESULTS: Two hundred three CD patients (49 biological, 93 conventional post-1998, 61 conventional pre-1998) were included in the study. Kaplan-Meier survivorship estimate shows that patients in the biological arm had a longer surgery-free survival compared to those in the conventional arm (p = 0.03). However, after propensity matching analysis, conducted on 143 patients, no significant difference was found in surgery-free survival (p = 0.3). A sub-group analysis showed shorter surgery-free survival in patients on conventional therapy in the pre-biologic era only (p = 0.02; Hazard Ratio 2.9; CI 1.01-8.54) while no significant difference was found between the biologic and conventional post-biologic groups (p = 0.15; Hazard Ratio 2.1; CI 0.69-6.44). CONCLUSION: This study shows that the introduction of biological therapy has only a slight impact on the eventual occurrence of surgery in CD patients over a long observation period. Nevertheless, biological therapy appears to delay the first intestinal resection.

The connection between diverticulosis and colonic superficial neoplastic lesions in patients who underwent screening colonoscopy.

PURPOSE: If could be a potential pathophysiological connection between colonic diverticula and colonic superficial neoplastic lesions, beyond the shared risk factors, has been a subject of debate in the last years. This study tries to evaluate the association between diverticulosis and colonic neoplastic lesions. METHODS: This is a cross-sectional study including asymptomatic patients who underwent a screening colonoscopy (patients with a positive fecal occult blood test under the regional program of colorectal cancer (CRC) screening), surveillance after polypectomy resection, or familiarity (first-degree relatives) between 2020 and 2021 to evaluate the association between diverticula and colonic polyps. A multivariate analysis with multiple logistic regression and odds ratio (OR) to study the independent association between adenomas and adenocarcinomas was performed. RESULTS: One thousand five hundred one patients were included. A statistically significant association between adenomas or CRC alone and colonic diverticula was found (p = 0.045). On a multivariate analysis of demographic (age, gender) and clinical parameters (familiarity for diverticula and adenoma/CRC), only age was significantly associated with the development of colorectal adenomas or cancer (OR 1.05, 95% CI 1.03-1.07, p < 0.0001). CONCLUSIONS: This study showed a statistically significant association between diverticula and colonic adenomas. However, it is impossible to establish a cause-effect relationship due to the intrinsic characteristics of this study design. A study with a prospective design including both patients with diverticulosis and without colonic diverticula aimed at establishing the incidence of adenoma and CRC could help to answer this relevant clinical question, since a potential association could indicate the need for closer endoscopic surveillance.

High- and intermediate-risk susceptibility variants in melanoma families from the Mediterranean area: A multicentre cohort from the MelaNostrum Consortium.

BACKGROUND: Most of large epidemiological studies on melanoma susceptibility have been conducted on fair skinned individuals (US, Australia and Northern Europe), while Southern European populations, characterized by high UV exposure and dark-skinned individuals, are underrepresented. OBJECTIVES: We report a comprehensive pooled analysis of established high- and intermediate-penetrance genetic variants and clinical characteristics of Mediterranean melanoma families from the MelaNostrum Consortium. METHODS: Pooled epidemiological, clinical and genetic (CDKN2A, CDK4, ACD, BAP1, POT1, TERT, and TERF2IP and MC1R genes) retrospective data of melanoma families, collected within the MelaNostrum Consortium in Greece, Italy and Spain, were analysed. Univariate methods and multivariate logistic regression models were used to evaluate the association of variants with characteristics of families and of affected and unaffected family members. Subgroup analysis was performed for each country. RESULTS: We included 839 families (1365 affected members and 2123 unaffected individuals). Pathogenic/likely pathogenic CDKN2A variants were identified in 13.8% of families. The strongest predictors of melanoma were ≥2 multiple primary melanoma cases (OR 8.1; 95% CI 3.3-19.7), >3 affected members (OR 2.6; 95% CI 1.3-5.2) and occurrence of pancreatic cancer (OR 4.8; 95% CI 2.4-9.4) in the family (AUC 0.76, 95% CI 0.71-0.82). We observed low frequency variants in POT1 (3.8%), TERF2IP (2.5%), ACD (0.8%) and BAP1 (0.3%). MC1R common variants (≥2 variants and ≥2 RHC variants) were associated with melanoma risk (OR 1.4; 95% CI 1.0-2.0 and OR 4.3; 95% CI 1.2-14.6, respectively). CONCLUSIONS: Variants in known high-penetrance genes explain nearly 20% of melanoma familial aggregation in Mediterranean areas. CDKN2A melanoma predictors were identified with potential clinical relevance for cancer risk assessment.

Hypersensitivity reactions to iodinate contrast media in Italy: a retrospective study. Characteristics of patients and risk factors.

SUMMARY: Objective. The purpose of the study was to describe the characteristics of patients experiencing hypersensitivity reactions (HRs) to iodinated contrast media (ICM) in a large Italian population and to investigate potential risks factors in order to obtain a risk stratification, helpful in the management of these patients. Methods. Data of 407 patients investigated in 9 Italian Allergy Centers for suspected HRs to ICM were analyzed and compared with a control group of 152 subjects that tolerated one or more ICM-enhanced examinations. The univariate and multivariate logistic regression model was used to evaluate associated factors. Results. The mean age of reactive patients was 61 years and 60% were female; 67% of patients reported immediate reactions and 35% experienced the reaction, more frequently with immediate onset, at the first examination in life. Iomeprol, iopromide and iodixanol were the most frequent culprit agents and 20% of patients showed a positive skin test result. Previous adverse reactions to ICM were reported by 15.6% of patients, whereas 35% of subjects experienced the reaction, more frequently immediate, after the first ICM-enhanced examination in their life. The multivariate analysis showed that male gender and age > 65 were associated with ICM reactions as protective factors [ORadja = 0.51; 95% CI: 0.33-0.77 and ORadja = 0.60; 95% CI: 0.39-0.92 respectively]. Cardio-vascular disease [ORadja = 2.06; 95% CI: 1.22-3.50)], respiratory allergy [ORadja = 2.30; 95% CI: 1.09-4.83)] and adverse drug reactions [ORadja = 1.99; 95% CI: 1.05-3.77)] were identified as risk factors for ICM reactions. Food allergy was not significantly associated with reactions [ORadja = 1.51; 5% CI: 0.41-5.56]. Conclusions. This is the largest study on Italian patients experiencing hypersensitivity reactions to ICM. Most results are in line with other studies, showing some association with factors that could influence the incidence of hypersensitivity reactions but not allowing an easy risk stratification.

The impact of COVID-19 pandemic on emergency services.

BACKGROUND: The SARS-Cov-2 pandemic has placed enormous strain on the global healthcare system. The strict containment measures have adversely affected population movements and mobility, daily activities, and the patterns of healthcare-seeking behavior. Although the Emergency and Admission Departments (EADS) activity has never been disrupted, the pandemic had a significant impact on the routine healthcare delivery. This study aims to assess the changes in healthcare delivery, with a focus on the elderly as a vulnerable component of the general population. DESIGN OF THE STUDY: Retrospective study. METHODS: All non-COVID visits to the EAD of the Local Health Unit (ASL1) in Abruzzo (Italy) from 9 March to 3 May 2020 were analyzed. These were compared to the hospital admissions recorded in the same period of the previous year. RESULTS: We found a 60.4% reduction in overall visits during the study period and an increase in the hospitalization rate from 30% to 39%. Emergency department visits have declined markedly for less acute medical conditions, while we have observed a statistically significant increase in the hospitalization rates for all age groups. Moreover, in 2020 we recorded a decrease in the ratio non-urgent/non-deferrable medical conditions for each age group; while the percentage of hospitalizations for each registered red code increased for each group, particularly for the 65-74 age group. CONCLUSIONS: The COVID-19 pandemic has significantly affected the care-seeking behavior of patients. During the COVID-19 epidemic, total hospital admissions have decreased, particularly for less severe illnesses, whereas the percentage of hospitalizations has increased. During 2020, hospital admissions for mild cases decreased, and patients presented to the EAD only in cases of acute medical condition, selecting those in need for more intensive care. However, several patients may have deferred necessary medical care even for potentially urgent conditions. Such reluctance to seek medical care may have caused delays in diagnosis. The impact of deferred care on patients' health is difficult to estimate at this time. This information will serve as a starting point for further research to improve healthcare management not only during emergency but also in non-emergency periods.

Clinical and seminal parameters associated with testicular microlithiasis and its severity in males from infertile couples.

STUDY QUESTION: Is there an association of testicular microlithiasis (TM) and its severity with testicular dysfunction in men from infertile couples? SUMMARY ANSWER: The presence of ≥5 testis microcalcifications per sonogram at the scrotal ultrasonography (US) of infertile males was associated with a more severe testicular dysfunction as compared to males with limited, or without, TM. WHAT IS KNOWN ALREADY: TM, representing an incidental finding in the scrotal US, is associated with male infertility and a higher risk for testicular cancer as compared to that in infertile males without TM. Still, there are unresolved questions on the relation between TM severity and testicular dysfunction in infertile men, as well as on the identification of risk factors for TM. STUDY DESIGN, SIZE, DURATION: This study was an observational, retrospective, case-control investigation involving males who underwent clinical evaluation, measurement of reproductive hormones, seminal analysis and scrotal US as part of diagnostic work-up for couple infertility at an andrology clinic, between January 2004 and December 2018. One hundred patients, out of the 2112 scored men, were found to have TM during the US evaluation. One hundred male partners from 100 infertile couples without TM, comprising the control group, were selected through a matched analysis by age and date of evaluation to reduce the confounding effect of both age and technique variability all along the long period of observation. PARTICIPANTS/MATERIALS, SETTING, METHODS: TM was defined as limited TM (LTM) or classical TM (CTM), when the maximum number of hyperecogenic spots per sonogram was <5 or ≥5, respectively. CTM, LTM and control groups were compared for clinical variables, serum levels of FSH, LH, and total testosterone, as well for semen parameters and scrotal US features. MAIN RESULTS AND THE ROLE OF CHANCE: After the exclusion of cases with testicular nodules to eliminate the possible confounding effect of testis cancer on testicular dysfunction, cases with CTM showed a lower mean testis volume (P = 0.03) and a lower sperm concentration (P = 0.03) as compared to the other two groups. A higher FSH level was observed in the CTM group compared to the LTM group (P = 0.02) and in controls (P = 0.009). The multiple logistic regression analysis showed that only a smaller testicle volume exhibited an independent significant association with a higher odds of detecting CTM (odds ratio = 0.84, 95% CI: 0.75-0.94; P = 0.02). No significant differences were observed between groups in the prevalence of risk factors for testicular cancer, or in the prevalence of conditions associated with TM. LIMITATIONS, REASONS FOR CAUTION: The retrospective design of the study did not allow conclusions to be drawn about the possible underlying links in the associations of TM with defective spermatogenesis. WIDER IMPLICATIONS OF THE FINDINGS: Males from infertile couples who exhibit a reduced testicular volume should undergo scrotal US, independent of sperm parameters, to exclude CTM and, eventually, testis cancer, although the association of CTM and current or future testis cancer risk is not yet clear. Evidence is provided here demonstrating that the presence of LTM has no clinical relevance in males from infertile couples.

Thyroid hormones modulate irisin concentrations in patients with recently onset hypothyroidism following total thyroidectomy.

PURPOSE: Irisin is a newly discovered adipo-myokine known for having significant effects on body metabolism. Currently, there is a discussion regarding the relation between thyroid function and irisin concentration. This study was designed to evaluate the influential role of levothyroxine replacement therapy on circulating levels of irisin in patients with recently onset hypothyroidism following total thyroidectomy. METHODS: Circulating levels of thyroid hormones, irisin and other metabolic parameters, were assessed in 40 recently thyroidectomized patients (34 females, mean age 50.1 ± 15.2 years) at baseline (5-7 day after surgery) and after 2 months under replacement therapy with levothyroxine. RESULTS: At baseline, circulating levels of thyroid hormones were indicative of hypothyroidism (TSH 12.7 ± 5.0 µU/mL, FT3 1.9 ± 0.7 pg/mL, FT4 8.7 ± 3.6 pg/mL). Mean serum irisin concentrations significantly increased after 2 months under replacement therapy with levothyroxine (from 2.2 ± 0.6 to 2.9 ± 0.6 µg/mL, p < 0.0001). Variations of circulating levels of irisin under levothyroxine replacement therapy were directly correlated with those of FT3 (Rho = 0.454, p = 0.0033) and FT4 (Rho = 0.451, p = 0.0035). Multivariate regression analysis revealed that changes in thyroid hormones concentrations explained up to 10% of the variations of serum irisin levels under levothyroxine replacement therapy (FT3 R2 = 0.098, FT4 R2 = 0.103). CONCLUSION: Our study suggests that levothyroxine replacement therapy mildly influences irisin metabolism in patients with recently onset hypothyroidism following total thyroidectomy.

Left spermatic vein reflux after varicocele repair predicts pregnancies and live births in subfertile couples.

PURPOSE: Varicocele repair (VR) is proposed to improve fertility in subfertile couples with a poor semen quality. We explored whether the disappearance of a left continuous spermatic venous reflux (SVR) at scrotal colour-Doppler ultrasound (CDUS), an objective evidence for a VR, is predictive for improved fertility outcome in subfertile couples. METHODS: VR was performed by left internal spermatic vein sclero-embolisation in 88 males seeking a consultation for subfertility. Semen analysis and scrotal CDUS were evaluated before and 6 months after VR. Serum levels of FSH and total testosterone (TT) were obtained at baseline. Telephone interview was used to obtain information about fertility outcome. Significant predictors of pregnancy and live births, selected by univariate analyses, were included into multiple logistic regression models to assess independent associations. RESULTS: At the adjusted model, independent significant predictors of pregnancy after VR were a disappeared SVR at CDUS (OR = 5.5, 97.5% CI 2.01-15.4; p = 0.0009) and an improved sperm total motile count (TMC) (OR = 5.5, 97.5% CI 1.4-27.9; p = 0.02). Even live births were independently associated with both disappeared left SVR at CDUS (OR = 4.3, 97.5% CI = 1.6-11.8; p = 0.003) and improved TMC after VR (OR = 4.8, 97.5% CI 1.3-24.2; p = 0.02). CONCLUSION: The still controversial effect of varicocele repair on fertility in subfertile couples may reside on the undefined objective methods to document a successful VR and its effect on couple fertility. The disappearance of a continuous left SVR at CDUS after VR was the objective best predictor for subsequent improved fertility in subfertile couples.

Replacement therapy with levothyroxine modulates platelet activation in recent-onset post-thyroidectomy subclinical hypothyroidism.

BACKGROUND AND AIM: Subclinical hypothyroidism has been linked to increased risk of atherosclerotic disease. Soluble CD40 ligand (sCD40L), mainly derived from activated platelets, and the lipid peroxidation product 8-iso-prostaglandin F2α (8-iso-PGF2α) are known to play a relevant pathophysiological role in atherogenesis. In this study, we analyzed the relationship between thyroid hormones and circulating levels of sCD40L and 8-iso-PGF2α in patient with recent-onset post-thyroidectomy subclinical hypothyroidism under replacement therapy. METHODS AND RESULTS: Circulating levels of thyroid hormones, sCD40L, and 8-iso-PGF2α were assessed in 40 recently thyroidectomized patients (33 females, mean age 52.0 ± 11.7 years) at baseline (5-7 day after surgery) and after 2 months under replacement therapy with levothyroxine (LT-4). At baseline, circulating levels of thyroid hormones were indicative of a subclinical hypothyroidism (TSH 7.7 ± 3.9 µU/mL, FT3 1.8 ± 0.6 pg/mL, and FT3 8.9 ± 3.0 pg/mL). Circulating levels of sCD40L and 8-iso-PGF2α were directly correlated with each other (r = 0.360, p = 0.023) and with TSH levels (r = 0.322, p = 0.043 and r = 0.329 p = 0.038, respectively). After 2 months under the replacement therapy with LT-4 circulating levels of TSH (from 7.7 ± 3.9 to 2.7 ± 2.8 µU/mL, p < 0.0001), sCD40L (from 6.11 ± 2.41 to 2.43 ± 2.00 ng/mL, p < 0.0001) and 8-iso-PGF2α (from 45.33 ± 6.94 to 40.36 ± 6.20, p < 0.0001) significantly decreased. Changes in circulating levels of sCD40L and 8-iso-PGF2α were directly correlated with each other (r = 0.349 p = 0.028) and with changes in TSH levels (r = 0.367 p = 0.020 and r = 0.339 p = 0.032, respectively). CONCLUSION: Our study suggests an influential role of TSH on proatherogenic activation of platelets, probably through enhanced lipid peroxidation. These findings could partially explain the increased susceptibility of patients with subclinical hypothyroidism to develop atherosclerotic disease.

Determination of spermatic vein reflux after varicocele repair helps to define the efficacy of treatment in improving sperm parameters of subfertile men.

PURPOSE: A continuous spermatic venous reflux (SVR) at colour Doppler ultrasound (CDU) is an evidence for varicocele, a frequent correlate for male subfertility. We explored whether SVR after left varicocele repair is predictive for changes in semen quality in subfertile men. METHODS: Blood hormones (FSH, LH, and total testosterone) and scrotal CDU were obtained in subfertile patients with left grade II or grade III varicocele on physical evaluation and a poor sperm quality. Semen analysis and CDU were re-evaluated 6 months after a retrograde internal spermatic vein scleroembolisation. RESULTS: The retrospective study included 100 men with a baseline SVR >3 cm/s; 60 men showed a disappearance (group 1) and 40 men (group 2) showed a reduced SVR after varicocele repair. Total motile sperm count (TMC) was markedly increased after treatment (p < 0.0001; F = 35.79) and the increase was more relevant in group 1 compared to group 2 (p = 0.04; F = 4.20). TMC and left SVR values after varicocele repair were negatively correlated (R = -0.218; p = 0.035). Multivariate analysis showed that adjusted SVR after repair negatively predicted TMC change (TMC after repair minus baseline TMC) (ß = -2.56; p = 0.022). Disappearance of a continuous left SVR at CDU after varicocele repair was associated to a better improvement of semen parameters in subfertile men. CONCLUSION: Recording of a continuous left spermatic vein reflux is an objective method to assess a successful varicocele repair aimed to improve sperm parameters in subfertile men.

Analgesia: effects on the first and second stages of labor.

BACKGROUND: This controlled observational study aimed at evaluating the effects of epidural analgesia on the first and second stages of delivery in nulliparous women, referred to the birth centers of the Sant'Omero "Val Vibrata" Hospital and the "San Salvatore" Hospital in L'Aquila, selected in accordance with specific inclusion criteria. MATERIALS AND METHODS: Between May Ws, 2012 and April 3 1s, 2013, 363 patients were enrolled at the birth centres of the "Val Vibrata" Hospital in Sant'Omero (TE) and of the "San Salvatore" Hospital in L'Aquila. 139 patients received epidural analgesia during labor at the "Val Vibrata" Hospital; 224 patients constituted the control group and went through natural delivery without analgesia at the "Val Vibrata" and "San Salvatore" hospitals. RESULTS: Dilation time was different in the two groups: in the group with analgesia, the median was 2.30 and 3.35 in the control group. The median expulsion time was 2.05 in the analgesia group and 0.40 in the control group. DISCUSSION: The statistical analysis of the study has highlighted the fact the analgesia influences the dilation and expulsion time of labor, confirming on the one hand the clinical evidence, and on the other, adding important results that have not been analyzed by other scientific studies. The results have shown that in nulliparous women, with spontaneous onset of labor, analgesia causes a major reduction in the dilation time of the cervical canal with respect to the control group.

Embolization of left spermatic vein in non-obstructive azoospermic men with varicocele: role of FSH to predict the appearance of ejaculated spermatozoa after treatment.

PURPOSE: Varicocele repair in non-obstructive azoospermia (NOA) was occasionally associated to ejaculated spermatozoa independently from clinical and laboratory measures. We performed a prospective study in infertile men affected by NOA and left side varicocele to find whether or not the appearance of ejaculated spermatozoa after varicocele repair is predicted by baseline measures. METHODS: Patients with NOA and grade II, or grade III left side varicocele were submitted to hormone analysis and to scrotal color Doppler ultrasound (CDU). Azoospermia was confirmed in 23 patients aged 25-47 years who were than submitted to varicocele repair through a retrograde internal spermatic vein embolization. Patients were re-evaluated after 6 months. RESULTS: Six months after varicocele repair 12 patients (52.2 %) were still azoospermic (Group 1) while 11 patients (47.8 %) reported ejaculated spermatozoa (Group 2) [sperm count: 1.3 × 10(6)/mL; 0.5 × 10(6)/mL-1.6 × 10(6)/mL (median 25th-75th centiles)]. Serum baseline FSH was lower in Group 2 compared to Group 1 (p = 0.012), while no differences between groups were revealed for all other clinical and laboratory parameters. ROC analysis indicated that baseline FSH level predicted the appearance of ejaculated spermatozoa after treatment [AUC = 0.811; 95 % Confidence Interval (CI) 0.6-0.9; p = 0.0029]. A cut-off level of FSH <10.06 mIU/mL identified 82.0 % of cases with ejaculated spermatozoa with a specificity of 81.8 % and a sensitivity of 83.3 %. CONCLUSION: Selected patients with NOA may show ejaculated spermatozoa after a non-invasive repair of a left side varicocele, therefore avoiding testicular sperm extraction. Baseline serum FSH was a valuable predictor for ejaculated spermatozoa after treatment.

Propensity adjusted appraisal of the surgical strategy for appendiceal carcinoids.

BACKGROUND: The treatment algorithm for appendiceal carcinoids is based on tumor size. We wanted to verify whether right hemicolectomy confers a survival advantage compared with appendectomy in patients with tumors larger than 2 cm. METHODS: Data regarding patients with primary carcinoid tumors of the appendix were collected from the Surveillance, Epidemiology, and End Results program database. A propensity score with respect to surgical intervention was calculated with a binary logistic regression including gender, stage of disease, and age as covariates. The groups were matched with a 1:1 ratio, using the nearest neighbor algorithm. A Cox proportional hazards model adjusted for propensity score was implemented to assess the impact of surgical intervention on overall survival. RESULTS: Only stage of disease differed between the groups (p = 0.011). After matching, based on the propensity score, our series was constituted of 109 patients undergoing appendectomy and 109 undergoing right hemicolectomy. The type of surgical intervention failed to reach statistical significance. CONCLUSIONS: Right hemicolectomy did not seem to confer any survival advantage on patients with appendiceal carcinoids with a diameter >2 cm. For this reason, tumor size should not be considered an absolute indication for right hemicolectomy.

Investigation of periodontal status in type 1 diabetic adolescents.

AIM: The purpose of this study was to evaluate the effects of type 1 diabetes and the possible role of metabolic control on the periodontal status of diabetic adolescents. MATERIALS AND METHODS: Three groups of 40 patients each were examined: diabetic subjects with a good metabolic control (well controlled WC) (glycated haemoglobin HbA1c ≤ 7%) (20 males and 20 females; mean age: 14.1 ± 1.5 years); diabetic subjects with poor metabolic control (poorly controlled PC) (glycated haemoglobin HbA1c> 7%) (20 males and 20 females; mean age: 14.5 ± 1.3 years); and patients in good general health, which constituted the control group (20 males and 20 females; mean age: 14.1 ± 1.2 years). For each subject, a periodontal evaluation was performed and the following parameters were assessed: Plaque Index (PI), Gingival Index (GI), Bleeding on probing (BOP), Probing Depth (PD), Clinical Attachment Level (CAL). Chi-square was used to compare categorical variables. Kruskal-Wallis one-way ANOVA by ranks was used to compare the quantitative variables (GBI, PD) among the 3 groups. Post-hoc comparison between pairs of groups was assessed by Wilcoxon's rank sum test, with a downward adjustment of the alpha level to compensate for multiple comparisons. RESULTS: The levels of PI in WC subjects (1.9 ± 0.8) and in PC subjects (2.1 ± 0.6) were significantly higher compared to healthy subjects in the control group (0.8 ± 0.7) (p <0.0001). Similarly, the GI in both PC (1.9 ± 0.8) and WC subjetcs (1.7 ± 0.9) was significantly higher (p <0.05) compared to controls (0.9 ± 0.8). GBI in the PC (60.2 ± 23.6%) and the WC (57.4 ± 22.5%) groups was significantly higher compared to healthy subjects (35.9 ± 18.7%) (p <0.05). The PD parameter was found significantly higher (p <0.05) in the PC group (26.7 ± 12.6) and WC group (23.5 ± 11.3%) compared with controls (8.3 ± 6.2%). Regarding the CAL, no significant differences were found between the groups (p> 0.05). In addition, the comparisons between groups PC and WC were not statistically significant (p> 0.05). CONCLUSIONS: Adolescents affected with type 1 diabetes show a higher level of bacterial plaque, gingival inflammation with bleeding on probing and probing depth, compared to healthy subjects. There were no significant changes with regard to the accumulation of plaque and periodontal status among diabetic patients both with good control and with poor metabolic control.

Ultrasonographic caput epididymis diameter is reduced in non-obstructive azoospermia compared with normozoospermia but is not predictive for successful sperm retrieval after TESE.

STUDY QUESTION: Is the ultrasonographic determination of the caput epididymis diameter predictive for sperm retrieval after testicular sperm extraction (TESE) in non-obstructive azoospermia (NOA)? SUMMARY ANSWER: Ultrasonographic determination of the caput epididymis diameter did not give any relevant clinical information in NOA and was not predictive for positive sperm retrieval after TESE. WHAT IS KNOWN ALREADY: The diameter of the caput epididymis in ultrasonography (US) has a diagnostic relevance in azoospermic men to correctly identify obstructive azoospermia; however, its clinical value in NOA is not yet determined. STUDY DESIGN, SIZE, DURATION: We performed a retrospective study of 100 azoospermic and 160 normozoospermic men attending a university infertility clinic. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were submitted to scrotal US to determine the mean value of bilateral testicular volumes (ml), the bilateral longitudinal caput diameter (mm) and the antero-posterior diameter of the corpus (mm) epididymis. The number of spermatozoa retrieved after TESE and the testicular histology of azoospermic men was obtained and the percentage of seminiferous tubules with elongated spermatids (%T) was used to classify cases with normal spermatogenesis (obstructive azoospermia) (OA) (n = 20; %T ≥ 80) or with NOA (n = 80; %T < 70). MAIN RESULTS AND THE ROLE OF CHANCE: The US testes volumes and caput diameters were reduced (P < 0.05) in NOA compared with OA and with normozoospermia, but the corpus values were not different. The caput diameter in the side submitted to biopsy was significantly reduced when germinal epithelium was absent (Sertoli cell only) (P < 0.05) and the lowest value of caput diameter was observed when the seminiferous epithelium and tubule lumen were absent (testicular hyalinosis). On the contrary, a total arrest of spermatogenesis at the first meiosis level, or a defect of spermiogenesis resulting in scattered elongated spermatids in each tubule, did not show a reduced diameter of caput epididymis compared with normozoospermia. The caput diameter did not show any difference between NOA patients with or without successful sperm retrieval at TESE. On the contrary testicular volume was significantly reduced in NOA patients with no sperm retrieval (P = 0.0037). The caput diameter was not correlated with the number of retrieved sperm, the serum level of follicle stimulating hormone, or with the percentage of tubules with elongated spermatids at histological analysis. LIMITATIONS, REASONS FOR CAUTION: The aetiology of NOA was not included in the statistical analysis due to the low rate of cases with a specific aetiology for a testicular failure. Larger studies should exclude the possibility that besides testicular histology, aetiology of NOA might influence the diameter of caput epididymis. Moreover, whether a reduced diameter of caput epididymis is only a result of a testicular pathologic phenotype or whether it may underscore a primitive dysfunction influencing the number of ejaculated spermatozoa is not yet determined. WIDER IMPLICATIONS OF THE FINDINGS: We reported that US diameter of the caput epididymis is reduced in cases of NOA but, in contrast with the testicular volume, it is independent of the completion of spermatogenesis and subsequent presence of spermatozoa in the epididymis. Therefore ultrasonographic determination of caput epididymis diameter is not predictive for positive sperm retrieval after TESE in cases of a primitive testicular failure. Our novel findings may help to define which reproducible parameters of scrotal US should be assessed in the work-up of male infertility.

The correspondence between abnormal transformation zone grade 1 and grade 2 colposcopic parameters and histology. Clinical implications.

OBJECTIVE: To analyse the correlation between the colposcopic parameters of Grade 1 and Grade 2 abnormal transformation zone (ANTZ G1-ANTZ G2) and histological examination of the cone. MATERIALS AND METHODS: A retrospective analysis of medical records of 600 women who underwent colposcopy and conisation (large loop excision of the transformation zone - LLETZ) between January 1, 2009 and July 31, 2012. The correlation between colposcopic and histological parameters was analysed using the Spearman nonparametric test. RESULTS: In ANTZG1 there was no correlation (r = - 0.03; p = 0.55); in ANTZG2 however, a low degree of correlation (r = 0.21; p = 0.03) was found. Sensitivity, specificity, and positive and negative predictive values of an ANTZ G2 colposcopic picture were 33.45% (confidence interval [CI] 95% 28.0% to 39.2%), 95.48% (CI 95% 92.5% to 97.5%), 87.4% (CI 95% 79.7% to 92.9%), and 60.5% (CI 95% 56% to 64.9%), respectively. CONCLUSIONS: The decisive factor in the diagnosis of the cervical oncologic pathologies is the histological examination of the cone, and not the colposcopy which should be seen as a "guiding" investigation in predicting conisation and application of the most appropriate treatment.

Impact of surgery and radiotherapy in women with uterine malignancies.

According to the National Health and Social Life Survey, sexual dysfunction affects about 43% of perimenopausal women. A diagnosis of cancer has a profound physical, emotional, and social impact, influencing the relationship with the body, the perception of illness and death, family, social and professional relationships, and the relationship with the partner and, consequently, sexuality. Loss of desire, dyspareunia, orgasmic disorder, difficulties in emotional and physical closeness to the partner, feelings of shame, and inadequacy commonly occur after treatment for uterine cancer; however, if these problems are associated with surgery or with radiotherapy, still remains unclear. According to this study, the authors may conclude that the experience of cancer could lead patients to a rediscovery of. their own sexuality and to an improvement in the relationship with their partner, showing that, sometimes, the relational and psychological factors assume greater importance than physical effects on sexuality, and they can somewhere compensate the morphofunctional failure.

Causes of hospitalisation before and after the 2009 L'Aquila earthquake.

On 6 April 2009, an earthquake struck L'Aquila. The San Salvatore Hospital was evacuated, and a field hospital was built. The study aimed to assess the epidemiologic impact of the earthquake through the analysis of patient population admitted to the field hospital during a 2-month period following the disaster. We retrospectively evaluated causes of hospitalisation and demographic data of patients admitted to (i) the Division of Internal Medicine and (ii) the Division of Emergency Medicine of the field hospital from 6 April, 2009 to 29 May, 2009. All data were compared with the admissions made at the same divisions of the San Salvatore Hospital during the same period of previous year. (i) Patient group (n = 102) and comparison group (n = 108). Mean patient age was higher, patients living in L'Aquila were more numerous, while mean length of stay was lower after than before the earthquake. Infectious diseases increased, while 'other' diseases decreased after the disaster both in admission and in discharge diagnoses. Gastroenterological diseases decreased with the earthquake but only in admission diagnoses. (ii) Patient group (n = 5255) and comparison group (n = 6564). Triage codes changed with the earthquake. Cardiovascular, psychiatric, gynaecological, infectious and chronic diseases increased, while pneumologic, gastroenterological, traumatic and 'other' diseases decreased after the quake. The number of hospitalised patients decreased with the tremor, while those discharged transferred to other hospitals and those who rejected hospitalisation increased. A natural disaster completely changes causes of hospitalisation in the Divisions of Internal and Emergency Medicine. These findings can be useful for the design of specific intervention programmes and for softening the detrimental effects of quakes.

Effects of correction of Class II malocclusion on the kinesiographic pattern of young adolescents: a case- control study.

AIM: The aim of this study was to assess the dynamic activity of the mandible by means of a computerised kinesiograph in Class II patients treated with orthodontic therapy and to compare the results of this group with those of a sample of untreated Class II patients. METHODS: Twenty young adolescents who had undergone orthodontic treatment for correction of Class II malocclusion and twenty age and sex-matched adolescents exhibiting Class II malocclusion, whose parents refused the orthodontic treatment, were enrolled. Maximum vertical opening (MVO), maximum anterior-posterior movement (MAPM), maximum right deviation (MRD), maximum left deviation (MLD), MVO/ MAPM ratio, maximum velocity in opening (MVIO), maximum velocity in closure (MVIC), verticality (ID-V), anterior-posteriority (ID-AP) and laterality (ID-L) were recorded during the kinesiographic evaluations. Differences in the kinesiographic data were analysed using the Wilcoxon sum rank test; data are expressed as means and standard deviations (SD). Differences between groups in age were analysed using unpaired t-test, while differences in gender distribution were assessed using the Fisher's exact test. The level of significance was set at p < 0.05. RESULTS: No differences were detected in the distribution of sex and age between the two groups. Significant differences between the two groups were observed for MVO, MAPM, that were higher in the control group, and MLD, which was higher in the case group; no other significant differences were detected for MRD, MVO/ MAPM, MVIO, MVIC, ID-V, ID-AP, ID-L. CONCLUSION: Orthodontic treatment of young patients with Class II malocclusion may reduce the maximum vertical opening as well as the maximum anterior-posterior movement and enhance the lateral displacement; however, further studies are needed to assess the relationship between impaired mandible kinetics of orthodontic treatment in patients with Class II malocclusion and craniomandibular disorders.
