Abstract Objectives The aim of the present study was to compare the accuracy of the conventional illumination method (CONV) and the fluorescence-aided identification technique (FIT) for distinguishing between composite restorations and intact teeth using different fluorescence-inducing devices commonly used for FIT. Materials and methods Six groups of six dentists equipped with one of six different FIT systems each independently attempted to identify composite restorations and intact teeth on a full-mouth model with 22 composite restorations using CONV and, 1 h later, FIT. The entire procedure was repeated 1 week later. Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values, including 95% confidence intervals (CI), were calculated for CONV and FIT overall and for each device. The influence of examiner age, method, and device on each parameter was assessed by multivariate analysis of variance. Results The sensitivity (84%, CI 81–86%), specificity (94%, CI 93–96%), PPV (92%, CI 90–94%), and NPV (90%, CI 88–91%) of FIT was significantly higher than that of CONV (47%, CI 44–50%; 82%, CI 79–84%; 66%, CI 62–69%, and 69%, CI 68–71%, respectively; p<0.001). The differences between CONV and FIT were significant for all parameters and FIT systems except VistaCam, which achieved no significant difference in specificity. Examiners younger than 40 years attained significantly higher sensitivity and negative predictive values than older examiners. Conclusions FIT is more reliable for detecting composite restorations than the conventional illumination method. Clinical relevance FIT can be considered an additional or alternative tool for improving the detection of composite restorations.

Healthcare workers are at the forefront against COVID-19, worldwide. Since Fondazione Policlinico Universitario A. Gemelli (FPG) IRCCS was enlisted as a COVID-19 hospital, the healthcare workers deployed to COVID-19 wards were separated from those with limited/no exposure, whereas the administrative staff were designated to work from home. Between 4 June and 3 July 2020, an investigation was conducted to evaluate the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin (IgG) antibodies among the employees of the FPG using point-of-care (POC) and venous blood tests. Sensitivity, specificity, and predictive values were determined with reverse-transcription polymerase chain reaction on nasal/oropharyngeal swabs as the diagnostic gold standard. The participants enrolled amounted to 4777. Seroprevalence was 3.66% using the POC test and 1.19% using the venous blood test, with a significant difference (p < 0.05). The POC test sensitivity and specificity were, respectively, 63.64% (95% confidence interval (CI): 62.20% to 65.04%) and 96.64% (95% CI: 96.05% to 97.13%), while those of the venous blood test were, respectively, 78.79% (95% CI: 77.58% to 79.94%) and 99.36% (95% CI: 99.07% to 99.55%). Among the low-risk populations, the POC test’s predictive values were 58.33% (positive) and 98.23% (negative), whereas those of the venous blood test were 92.86% (positive) and 98.53% (negative). According to our study, these serological tests cannot be a valid alternative to diagnose COVID-19 infection in progress.

An appropriate diagnosis is required to avoid unnecessary surgery for gallbladder cholesterol polyps (GChPs) and to appropriately treat pedunculated gallbladder carcinomas (GCs). Generally, polyps >10 mm are regarded as surgical candidates. We retrospectively evaluated plain and contrast-enhanced (CE) computed tomography (CT) findings and histopathological features of 11 early GCs and 10 GChPs sized 10–30 mm to differentiate between GC and GChP >10 mm and determine their histopathological background. Patient characteristics, including polyp size, did not significantly differ between groups. All GCs and GChPs were detected on CE-CT; GCs were detected more often than GChPs on plain CT (73% vs 9%; p < 0.01). Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy for GCs were 73%, 90%, 89%, 75%, and 81%, respectively. On multivariate analysis, lesion detectability on plain CT was independently associated with GCs (odds ratio, 27.1; p = 0.044). Histopathologically, GChPs consisted of adipose tissue. Although larger vessel areas in GCs than in GChPs was not significant (52,737 μm2 vs 31,906 μm2; p = 0.51), cell densities were significantly greater in GCs (0.015/μm2 vs 0.0080/μm2; p < 0.01). Among GPs larger than 10 mm, plain CT could contribute to differentiating GCs from GChPs.

Objective To evaluate the diagnostic accuracy and agreementbetween the 1980 and 1990 WHO criteria for determining the de-gree of dehydration in children with acute diarrhea.Methods This prospective study was conducted in two hospitalsfrom October 2002 to February 2003. Clinical signs of dehydrationall patients were recorded. The degree of dehydration based onthe 1980 and 1990 WHO criteria was determined and comparedwith fluid deficit measured by the difference of body weight on ad-mission and on discharge. Chi-square test and kappa value analy-ses were performed. Sensitivity, specificity, predictive values, andaccuracy of each WHO criteria were assessed. The prevalence ofdehydration was also determined.Results Sixty-five patients, comprising 40 boys and 25 girls, werestudied. There was a significant difference between the two WHOcriteria in differentiating between dehydration and non-dehydra-tion (P<0.05). Based on the 1980 WHO criteria the prevalence ofdehydration was 62.2%. Its sensitivity, specificity, and accuracy indiagnosing dehydration were 100.0%, 55.5%, and 86.2%, respec-tively. Based on the 1990 WHO criteria, the prevalence of dehy-dration was 60.0%. Its sensitivity, specificity, and accuracy in diag-nosing dehydration were 94.9%, 46.1%, and 75.4%, respectively.There was also a significant difference between both criteria indetermining severe dehydration (P<0.05). Based on the 1980 cri-teria, the prevalence of severe dehydration was 15.4%. Its sensi-tivity, specificity, and accuracy in diagnosing severe dehydrationwere 30.0%, 94.5%, and 84.6%, respectively. Based on the 1990criteria, these results were 40.0%, 94.5%, and 86.2%, respectively.The prevalence was 15.4%. Kappa value comparing the two WHOcriteria was 0.852 in diagnosing dehydration and 0.915 in diag-nosing severe dehydration. There was no significant differencebetween the two criteria in their sensitivity and specificity (P>0.05).Conclusion Both WHO criteria can be applied to determine de-hydration in patients with acute diarrhea, although we feel that the1990 criteria is simpler

Early diagnosis of an infection and prompt administration of an antibiotic can dramatically reduce morbidity and mortality.Procalcitonin (PCT), a precursor of calcitonin, has been proposed as a marker of bacterial infection. The aim of this study is to assess theefficiency of procalcitonin in children for the diagnosis of bacterial vs. non bacterial infection. This was a prospective, cross-sectional study.The subjects were enrolled consecutively, consisting of feverish children (temperature ³38.5° C) admitted to the Pediatric EmergencyDepartment with ages up to 12 years old. The subjects were divided into two groups according to their final diagnosis, bacterial and nonbacterial infection. Serum PCT concentration was measured by enzyme linked fluorescent assay (ELFA) method. Sensitivity, specificity,positive predictive and negative predictive values, and receiver operating curve (ROC) of PCT were calculated. Out of 54 patients,24 (44.4%) had a final diagnosis of bacterial infection. PCT showed a wide concentration range in the bacterial infection group (median:1.09 ng/mL, lower (L)=0.05 ng/mL, upper (U)=128.7 ng/mL) compared with non bacterial infection group (0.21 ng/mL; L=0.05ng/mL; U=12.15 ng/mL). There was a significant difference in PCT between the 2 groups (p=0.020). ROC analysis demonstrated anarea under curve (AUC) of 0.686 (95% CI, 0.534 to 0.838). Using a cut-off point of 0.5 ng/mL, the sensitivity, and specificity, positivepredictive and negative predictive values of PCT were 66.7%, 76.7%, 69.6%, 74.2%, respectively. In this study, PCT may be useful fordifferentiation of bacterial vs. non bacterial infection in children.

A Prospective Study

Confirmation of endotracheal tube appointment is of critical importance, since unrecognized esophageal intubation can be rapidly lethal (death, brain damage). The aim of our study was to compare four different methods for prediction of difficult intubation: Mallampati, Thyro-mental distance, ULBT (Upper Lip Bite Test), and Inter incisicor gap. In a prospective study, 448 patients with a mean age of 53.5 who were scheduled for elective surgery were selected randomly and enrolled. Before induction of anesthesia, the airways were assessed by Mallampati test, Thyro mental distance, Upper lip bit test(ULBT) and Inter incisor gap. Laryngoscopic view according to the Cormack and Lehane grading system was determined after induction of anesthesia and Grades 3 and 4 defined as “difficult intubation.” Degree of observed difficulty of intubation was compared to predicted values. Sensitivity, specificity, positive and negative predictive values and accuracy of these tests and their combinations with the ULBT were calculated. Statistical analysis was performed using SPSS version 16. Data were analysis by using Fishers exact and McNemar's test, and a Pvalue. <0.05 was considered statistically significant.  The prevalence of difficult intubation Cormack-Lehane in this study was 8.4%, Mallampati test had the highest sensitivity (47.3%) and Thyro-mental distance was most specific (96%). The ULBT (upper lip bite tests) had most positive and negative predictive value (37.9% & 93. 5%).Data also showed that power of these tests in predicting easy intubation is more than their ability in assessing the likelihood of difficult intubation. There was no significant difference regarding difficult intubation based on gender (P < 0.05), whereas there were significant differences between the older tests and laryngeal view (P < 0.05, Mc-Nemar test). Despite the validity of MMP, TMD, ULBT and IIG in predicting easy intubation is much greater than the value in prediction of difficult intubation; however, the simplicity of performing these tests and results of the four tests in evaluating patients before surgery by combination of tests in predicting difficult intubation will likely safe. It seems that best results are from applying combined test than a single one.

Background The estimation of glomerular filtration rate (GFR) is routinely used in the assessment of renal function in children. An accurate measurement of GFR is very helpful in detecting renal disease.Objective The aim of this study was to compare GFR calculated by Schwartz's formula and that assessed by creatinine clearance measurement.Methods A study to evaluate GFR calculated by the Schwartz's fonnula and by the conventional creatinine clearance method was done on 114 (57%) boys and 86 (43%) girls aged 6-13 years hospitalized in the Department of Child Health, Hasanuddin University, Wahidin Sudirohusodo Hospital, Makassar in 1996.Results This study showed that there was no significant difference between the value of GFR determined by the conventional creatinine clearance method and that calculated by the Schwartz's fonnula according to age and sex. Our findings also did not show any  difference of GFR assessed by both methods according to nutritional status of children. In regard to the accuracy of Schwartz's fonnula, the sensitivity, specificity, positive, and negative predictive values were 87.5%, 98.86%, 9 1.3%, and 98.3%, respectively.Conclusion It seems that Schwartz's fonnula might be used for assessing GFR in children particularly if either there is no facility for measuring creatininuria or there is difficulty in collecting complete and accurate-timing urine samples. The formula is a very simple and inexpensive method for determining GFR in children compared to the conventional creatinine clearance method.

Objective. To evaluate the diagnostic value of gastrin-17 (G-17) and pepsinogen (PG) in gastric cancer (GC) screening in China, especially eastern China, and to determine the best diagnostic combination and threshold (cutoff values) to screen out patients who need gastroscopy. Methods. The serum concentrations of G-17 and pepsinogen I and II (PGI and PGII) in 834 patients were analyzed, and the PGI/PGII ratio (PGR) was calculated. According to pathological results, patients can be divided into chronic nonatrophic gastritis (NAG)/chronic atrophic gastritis (CAG)/intraepithelial neoplasia (IN)/GC groups. The differences in G-17, PG, and PGR in each group were analyzed, and their values in GC diagnosis were evaluated separately and in combination. Results. There were differences in serum G-17, PGII, and PGR among the four groups (NAG/CAG/IN/GC) ( P ≤ 0.001 ). In total, 54 GC cases were diagnosed, of which 50% were early GC. There was no significant difference in the PGI levels among the four groups ( P = 0.377 ). NAG and CAG composed the chronic gastritis (CG) group. The G-17 and PGII levels in the IN and GC groups were higher than those in the CG group (both P ≤ oth   C ), while the PGR levels were lower ( P ≤ lower ). When distinguishing NAG from CAG, the best cutoff value for G-17 was 9.25 pmol/L, PGII was 7.06 μg/L, and PGR was 12.07. When distinguishing CG from IN, the best cutoff value for G-17 was 3.86 pmol/L, PGII was 11.92 μg/L, and PGR was 8.26. When distinguishing CG from GC, the best cutoff value for G-17 was 3.89 pmol/L, PGII was 9.16 μg/L, and PGR was 14.14. The sensitivity, specificity, accuracy, and positive and negative predictive values of G-17/PGII/PGR for GC diagnosis were 83.3%/70.4%/79.6%, 51.8%/56.3%/47.8%, 53.8%/57.2%/49.9%, 10.7%/10.9%/9.6%, and 97.8%/96.5%/97.1%, respectively. The sensitivity, specificity, accuracy, and positive predictive and negative predictive values of PGII/G-17 vs. PGR/G-17 vs. PGR/PGII in the diagnosis of GC were 63.0% vs. 70.4% vs. 64.8%, 70.5% vs. 70.1% vs. 60.4%, 70.0% vs. 70.1% vs. 60.7%, 12.9% vs. 14.0% vs. 10.2%, and 96.5% vs. 97.2% vs. 96.1%, respectively. Conclusion. The PGII and G-17 levels in patients with gastric IN and GC were significantly increased, while the serum PGR level was significantly decreased. Serological detection is effective for screening GC. The combination of different markers can improve the diagnostic efficiency. The highest diagnostic accuracy was G-17 combined with PGR, and the best cutoff values were G − 17 > 3.89   pmol / L and PGR < 14.14 .

A study to determine the sensitivity, specificity, and positive and negative predictive values of several clinical diagnostic tests of subcutaneous Achilles tendon rupture was performed during a 13-year period. There were 174 patients with clinical diagnosis of unilateral complete subcutaneous Achilles tendon tear and 28 patients with unilateral suspected but no actual Achilles tendon tear. The following tests were used: palpation, calf squeeze, Matles, Copeland, and O'Brien. Palpation of the gap was the least sensitive clinical test with the patient awake (0.73), increasing to 0.81 when the test was performed under anesthesia; the Copeland and O'Brien tests showed a sensitivity of 0.8. Both the calf squeeze and Matles tests were significantly more sensitive than the other tests (0.96 and 0.88, respectively; 0.022 P 0.05). All tests showed a high positive predictive value, with no statistically significant difference between the various tests. In the 28 patients with no evidence of a subcutaneous Achilles tendon tear on imaging, the tests showed a high capability to detect that the Achilles tendon was intact (gap palpation specificity, 0.89; calf squeeze test specificity, 0.93; Matles test specificity, 0.85). Whichever tests were performed, at least two of them were positive for a subcutaneous tear of the Achilles tendon in all patients in this study.

Abstract Purpose The aim of this study is to investigate the correlation between the magnetic resonance imaging (MRI) and intraoperative findings of deep infiltrating endometriosis using the #ENZIAN score. Methods This retrospective study included 64 patients who underwent surgery for deep infiltrating endometriosis between January 2017 and August 2020. Preoperative abdominopelvic MRI assessment was evaluated and scored using the #ENZIAN classification. Operative scores were considered the gold standard, and the sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of MRI for each category were calculated. Results MRI has higher sensitivity and specificity in showing the lesions of the compartments O (ovarian lesions), A (rectovaginal septum and posterior vaginal fornix), and B (uterosacral ligaments and parametrium) (100–100%, 100–100%, and 97–100%, respectively, p<0.001) compared to the other compartments. The lowest sensitivity, specificity, accuracy, and PPV of the MRI was found in compartment P (14%, 76%, 70%, and 7%, respectively). Conclusion We demonstrated that the #ENZIAN classification in MRI reports has significant sensitivity and specificity in compartments A, B (uterosacral ligaments and parametrium), and O. Furthermore, the determination of peritoneal lesions via MRI is inadequate.

Background: Early detection and start of antibiotic therapy neonatal sepsis (N.S) dramatically improves outcomes, so it is important to perform fast, reliable and specific early laboratory biomarkers. Aim: This study aimed to detect the prevelance, the risk factors, hematology profile, microbial profile of neonatal sepsis patients and also investigate the value of PCT and CRP, in comparison to presepsin in establishing the early diagnosis of neonatal sepsis. Methods: A cross sectional study was performed from March to September 2019 in Al Quwayiyah General hospital involving 120 neonates who were classified into 3 groups. The patients groups were: Proved N.S, suspected N.S and control healthy neonates, classified depending on Tollner score. Haematology profile and blood culture for each neonate were done. CRP, PCT and presepsin values were analyzed, compared, and their effectiveness as diagnostic markers was determined. Sensitivity, specificity, positive, and negative predictive values of the markers were calculated. Results: The prevelance of neonatal sepsis was 20.8%. 75 neonates were males and 45 neonates were females. 74 neonates were preterm, while 46 were full term. Gestational age in weeks was 31.1±5.9w for neonates with proved sepsis, 32.4±6.7w for neonates with suspected sepsis and 36.4±4.4w for control group. The mean birth weight was 1740±105.3 g for neonates with proved sepsis, 32.4±6.7 g for neonates with suspected sepsis, 2.650±205.2 g for control group. 36 babies suffered from respiratory distress syndrome, 10 had jaundice, 8 had cough, 28 had fever and 8 complained of other symptoms. Blood cultures were positive for all patients of proved sepsis. The identified bacteria included Gram positive bacteria 22(55%) which were Coagulase negative staph. 13(32.5%) followed by Staphylococcus aureus 4(10%) while Gram negative bacteria 15(37.5%) which were E. coli 5(12.5%) followed by Klebsiella peumoniae and also fungal infection (Candida species) detected in 3(7.5%) cases. There was significant difference between the mean and standared deviation of CRP, PCT and presepsin levels in proved and suspected N.S. groups when compared with healthy controls (P< 0.05). CRP sensitivity and specificity (72%, 61% respectively) which were less useful in diagnosis of neonatal sepsis compared to presepsin which has the highest sensitivity and specificity (95%, 81% respectively) followed by procalcitonin with sensitivity and specificity (90%, 69% respectively). Conclusion: The prevalence of neonatal sepsis among all admitted neonates in Al-Quwayiyah general hospital was 20.8%. Our results also detected higher sensitivity, specificity and positive and negative predictive values for presepsin more than and PCT CRP in the diagnosis of NS.
