To study the long-term outcomes of standard ILM peeling and fovea sparing with inverted flap (FSIF) peeling for symptomatic myopic foveoschisis (MF). This retrospective observational study included 36 eyes of 34 consecutive patients who underwent vitrectomy with standard ILM peeling and FSIF peeling for MF between April 2012 and march 2020. The primary outcome measures included best-corrected visual acuity (BCVA) and central foveal thickness (CFT) at 1 month and final visit and postoperative development of macular hole. There were 14 eyes in the standard ILM peeling group and 22 eyes and in the FSIF peeling groups with a mean FU of 34.2 months (SD 23.3; min. 12–max. 96) and 27.7 months (SD 14.9; min. 12–max. 63), respectively. In both groups BCVA was not significantly improved at 1 month but improved at last visit from 0.55 ± 0.21 to 0.37 ± 0.29 in the standard ILM peeling group (P = 0.0154) and from 0.57 ± 0.27 to 0.28 ± 0.23 in the FSIF peeling group (P < 0.0001). At 1 month and final visit CMT decreased from 572 ± 183.5 µm to 277.5 ± 95.2 µm and to 250.4 ± 96.1 µm, respectively, in the standard ILM peeling group and from 589.9 ± 189.8 µm to 383 ± 110.1 µm and 162.3 ± 74.8 µm in the FSIF peeling group (P < 0.001 for both groups at both time-points). The preoperative and postoperative BCVA and CMT showed no significant differences between groups. Three of the eyes in the standard ILM peeling group developed postoperative macular hole at 1, 10, 24 months, respectively, and none of the eyes in the FSIF peeling group. Multivariate analysis revealed that a better BCVA was the only independent factor correlated with the final BCVA. In this study, standard ILM peeling and FSIF peeling were both beneficial in improving the anatomy and function of eyes with MF. Postoperative MH may occur up to 2 years after standard peeling and seem effectively prevented by FSIF peeling.

Purpose The purpose of this study was to assess the clinical outcomes of the implantation of an aliphatic polyurethane scaffold for the treatment of partial loss of meniscal tissue at a mean follow-up of 36 months. Methods A retrospective review on prospectively collected data was performed on patients who underwent implantation of an aliphatic polyurethane-based synthetic meniscal scaffold. Patients were evaluated for demographics data, lesion and implant characteristics (sizing, type and number of meniscal sutures), previous and combined surgeries and complications. Clinical parameters were rated using NRS, IKDC subjective, Lysholm, KOOS, and Tegner activity score, both preoperatively and at final follow-up. Results Sixty-seven patients were evaluated at a mean follow-up of 36 months (48 M and 19 F; mean age 40.8 ± 10.6 years; mean BMI 25.4 ± 4.3). The scaffold was implanted on the medial side in 54 cases, and on the lateral one in 13. Forty-seven patients had undergone previous surgical treatment at the same knee and 45 required combined surgical procedures. All evaluated scores improved significantly from the baseline. Among possible prognostic factors, a delayed scaffold implantation had lower post-operative clinical scores: IKDC subjective ( P  = 0.049), KOOS Sport ( P  = 0.044), KOOS total ( p  = 0.011), and Tegner ( P  = 0.03) scores at follow-up. Conclusions The polyurethane meniscal scaffold implantation led to a significant clinical benefit in a large number of patients. A delayed intervention correlated with worse results. Level of evidence IV.

Purpose To report outcomes of pars plana vitrectomy (PPV) with air tamponade for primary rhegmatogenous retinal detachment (RRD) and investigate the impact of vitreous cortex remnants (VCR) on surgical outcomes. Methods A retrospective review of 900 patients treated for uncomplicated primary RRD between 2007 and 2020. Exclusion criteria included axial length > 26 mm, prior retinal surgery, giant retinal tear, PVR grade > B, and inadequate follow-up. Primary outcomes were retinal reattachment rate and best-corrected visual acuity (BCVA). Results Of 900 patients, 397 met inclusion criteria. Primary reattachment rate was 88.4%, with significant BCVA improvement. Forty-six eyes experienced RRD recurrence. Complications included cataracts (38.8%), IOP rise (11.4%), and macular edema (8.3%). Better final BCVA was associated with preoperative macular non-involvement and absence of reinterventions. No significant association was found between RRD recurrence and various factors, including VCR removal. Conclusion Air tamponade is a safe and effective option for primary RRD treatment. It has no negative effect on the environment and creates less discomfort for patients. VCR removal did not significantly reduce RRD recurrence in the overall number of cases. Further research will help determine the role of VCR in RD recurrence and define in which cases their removal might be beneficial.

BackgroundAnastomotic leakage (AL) and major complications after colorectal resection for deep infiltrating endometriosis (DIE) have a remarkable impact on patient outcomes. The aim of this study is to assess the predictive value of C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBCs) and the Dutch Leakage Score (DLS) as reliable markers in the early diagnosis of AL and major complications after laparoscopic colorectal resection for DIE.Methods262 consecutive women undergoing laparoscopic colorectal resection for DIE between September 2017 and September 2018 were prospectively enrolled. WBCs, CRP, PCT and DLS were recorded at baseline and on postoperative day (POD) 2, 3 and 6 then statistically analyzed as predictors of AL and severe postoperative complications.ResultsThe AL rate was 3.2%. The major morbidity rate was 11.2%. No postoperative mortality was recorded. The postoperative trend of DLS and serum levels of CRP and PCT, but not WBCs, were significantly higher in women developing AL and severe complications. DLS had better sensitivity and specificity than biomarkers on all postoperative days as a predictor of AL and major complications. CRP and PCT have a low positive predictive value (PPV) and a high negative predictive value (NPV) for AL and major complications on POD3 and POD6. The risk of malnutrition was significantly related to AL.ConclusionsThe combination of DLS as a standardized postoperative clinical monitoring system and CRP and PCT as serum biomarkers, allows the exclusion of AL and major complications in the early postoperative period after laparoscopic colorectal resection for DIE, thus ensuring a safe patient discharge.

Schistosomiasis is a neglected infection affecting millions of people, mostly living in sub-Saharan Africa. Morbidity and mortality due to chronic infection are relevant, although schistosomiasis is often clinically silent. Different diagnostic tests have been implemented in order to improve screening and diagnosis, that traditionally rely on parasitological tests with low sensitivity. Aim of this study was to evaluate the accuracy of different tests for the screening of schistosomiasis in African migrants, in a non endemic setting. A retrospective study was conducted on 373 patients screened at the Centre for Tropical Diseases (CTD) in Negrar, Verona, Italy. Biological samples were tested with: stool/urine microscopy, Circulating Cathodic Antigen (CCA) dipstick test, ELISA, Western blot, immune-chromatographic test (ICT). Test accuracy and predictive values of the immunological tests were assessed primarily on the basis of the results of microscopy (primary reference standard): ICT and WB resulted the test with highest sensitivity (94% and 92%, respectively), with a high NPV (98%). CCA showed the highest specificity (93%), but low sensitivity (48%). The analysis was conducted also using a composite reference standard, CRS (patients classified as infected in case of positive microscopy and/or at least 2 concordant positive immunological tests) and Latent Class Analysis (LCA). The latter two models demonstrated excellent agreement (Cohen's kappa: 0.92) for the classification of the results. In fact, they both confirmed ICT as the test with the highest sensitivity (96%) and NPV (97%), moreover PPV was reasonably good (78% and 72% according to CRS and LCA, respectively). ELISA resulted the most specific immunological test (over 99%). The ICT appears to be a suitable screening test, even when used alone. The rapid test ICT was the most sensitive test, with the potential of being used as a single screening test for African migrants.

We used random sampling to estimate the prevalence of severe acute respiratory syndrome coronavirus 2 infection in Verona, Italy. Of 1,515 participants, 2.6% tested positive by serologic assay and 0.7% by reverse transcription PCR. We used latent class analysis to estimate a 3.0% probability of infection and 2.0% death rate.

Background Histoplasmosis is a fungal infection highly endemic in the American continent. The disease can be severe in immunocompromised subjects. In immunocompetent subjects the clinical manifestations are variable. Aim of this work was to review the cases of acute histoplasmosis in immunocompetent travelers reported in literature. Methods A systematic review of literature was conducted. Electronic search was performed in Pubmed and LILACS. Two reviewers independently extracted data on demographic, clinical and radiological features, and treatment. Cases were classified according to Wheat’s definitions. Results Seventy-one studies were included in the analysis, comprising a total of 814 patients. Twenty-one patients diagnosed at the Centre of Tropical Diseases, Negrar (VR), Italy were also included. The most common travel destination was Central America (168 people, 29.8%); the most common way of exposure to histoplasma was the exploration of caves and/or contact with bat guano (349 people, 60.9%). The multivariate logistic regression model showed association between the development of disseminated histoplasmosis (DH) and activities that involved the exploration of caves and/or the contact with bats’ guano (adjusted OR: 34.20 95% CI: 5.29 to 220.93) or other outdoor activities (adjusted OR: 4.61 95% CI: 1.09 to 19.56). No significant difference in the attack rate between countries of destination was observed ( p -value: 0.8906, Kruskal-Wallis test). Conclusions Histoplasmosis often causes no or mild symptoms in immunocompetent individuals, although a severe syndrome may occur. The infection can mimic other diseases, and the epidemiological risk of exposure is an important clue to raise the index of suspicion.

PurposeTo report a longitudinal analysis of specific optical coherence tomography (OCT) features in eyes with diabetic macular edema (DME) treated with anti-VEGF.MethodsA total of 133 eyes of 103 consecutive patients with center-involving DME were included in the study. The eyes were treated between August 2008 and April 2019 with three monthly intravitreal anti-VEGF injections, either with or without prompt or deferred laser, followed by pro re nata (PRN) re-treatment. The following OCT biomarkers were evaluated: subfoveal neuroretinal detachment (SND) (defined as present (SND+) or absent (SND-)), hyperreflective retinal foci (HRF) number (defined as: absent/few(HRF-) or moderate/many (HRF+)), external limiting membrane (ELM) integrity, central macular thickness (CMT), and central retinal thickness (CRT). Changes in SND status and in the number of HRF were evaluated at each DME recurrence throughout the follow-up(FU) period. Mutual correlation among OCT biomarkers and their relationship with visual and anatomic outcomes were assessed both at baseline and over the FU period.ResultsThe mean FU was 71.2 months (SD 28.4; min. 12–max. 111). At baseline, the prevalence of SRD+ was 27.8% and a high number of HRF were detected in 41.4% of the eyes. A significant reduction in the number of HRF, CMT, CRT, and in the prevalence of SND was recorded in the post-loading phase (p-value <0.0001). In DME recurrences, the presence of SND+ and HRF+ was significantly more frequent in eyes with baseline SND+ and HRF+ compared to eyes presenting baseline SND- and HRF- (p-value <0.0001). No role of SND (p-value: 0.926) and HRF (p-value: 0.281) as baseline predictors of visual and anatomic outcomes was demonstrated, while a worse visual outcome was significantly correlated with a higher incidence of relapsing SND+ (p-value <0.0001) and HRF+ (p-value <0.0028) throughout the FU period.ConclusionIn this study, SND and HRF were frequently present in DME recurrences with the same pattern exhibited at baseline, suggesting that these OCT biomarkers may characterize a specific pattern of DME that repeats over time. Moreover, the results suggested that the persistence and recurrence of SND and HRF may account for a decrease in visual function more than the baseline prevalence of these biomarkers. Further studies are required to confirm these findings.

Purpose: to outline the role of CT in pre- and post-treatment evaluation in the case of lumbar endoscopic foraminotomy. Methods: This prospective study, conducted between September 2020 and January 2024, included consecutive patients with clinical symptoms of lumbar sciatica/lumbalgia/lombo-cruralgia/lower limb peripheral neuropathy. Pre- and post-foraminotomy CT imaging was used to assess the foraminal diameters (cranio-caudal, transverse and free hand ROI area) before and after the treatment. Two independent blinded readers assessed the CT randomly. VAS pain scale and the measurements of each foramen were compared before and after treatment. Interobserver agreement was assessed using the Intraclass Correlation Coefficient (ICC). Results: A total of 47 participants were enrolled, with 53 intervertebral levels analyzed. The mean VAS value decreased from 9.17 in the preoperative period to 0.66 at the one-month postoperative follow-up. The clinical response was associated with statistically significant changes in the cranio-caudal and transverse diameters, as well as the area of the treated neuroforamina (p-values < 0.05). Inter-rater reliability between the two operators ranged from 0.75 to 0.90. Conclusions: CT can demonstrate a significant enlargement of the neuroforaminal diameters after the endoscopic foraminotomy, with good correlation with clinical improvement.

PurposeScreening commercial drivers (CDs) for obstructive sleep apnea (OSA) reduces the risk of motor vehicle accidents. We evaluated the accuracy of standard OSA questionnaires in a cohort of CDs.Study design and methodsWe enrolled consecutive male CDs at 10 discrete transportation companies during their yearly scheduled occupational health visit. The CDs had their anthropometric measures taken; completed the Berlin, STOP, STOP-BANG, OSAS-TTI, SACS, EUROSAS, and ARES questionnaires; and underwent a home sleep apnea test (HSAT) for the determination of their respiratory events index (REI). We assessed the questionnaires’ ability to predict OSA (REI ≥ 5 events/h) and moderate-to-severe OSA (REI ≥ 15 events/h).ResultsAmong 315 CDs recruited, 243 (77%) completed the study protocol, while 72 subjects were excluded for inadequate HSAT quality. The demographics and clinical data were comparable in both the included and excluded subjects. The included CDs had a median age of 50 years (interquartile range (IQR) 25–70) and a mean body mass index of 27 ± 4 kg/m2. One hundred and seventy-one subjects (71%) had OSA, and 68 (28%) had moderate-to-severe OSA. A receiver operating characteristic curve of the questionnaires were 0.51–0.71 for predicting OSA and 0.51–0.66 for moderate-to-severe OSA. The STOP-BANG questionnaire had an unsatisfactory positive predictive value, while all of the other questionnaires had an inadequate negative predictive value.ConclusionsStandard OSA questionnaires are not suited for screening among CDs. The use of the HSAT could provide an objective evaluation of for OSA in this special population.
