Initial evaluation of chronic shoulder disability is a diagnostic challenge due to the anatomic complexity of the shoulder joints. For this purpose, several diagnostic tools utilizing provocative testing exist, but only a few have a reliable basis for their diagnostic value. Therefore, objectively determining the predictive value of these tests in identifying the precise anatomical source for disability—subacromial, intraarticular or other—is essential in order to proceed with further imaging evaluations for final objective diagnoses. Using validated clusters of provocative tests should improve their diagnostic values.

This study aimed to investigate whether the incorporation of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) into the international consensus guidelines (ICG) for the management of intraductal papillary mucinous neoplasm (IPMN) could improve its malignancy diagnostic value. In this single-center retrospective study, 109 patients diagnosed with IPMN who underwent preoperative CH-EUS between March 2010 and December 2018 were enrolled. We analyzed each malignancy diagnostic value (sensitivity (Se), specificity (Sp), positive predictive value (PPV), and negative predictive value (NPV)) by replacing fundamental B-mode EUS with CH-EUS as the recommended test for patients with worrisome features (WF) (the CH-EUS incorporation ICG) and comparing the results to those obtained using the 2017 ICG. The malignancy diagnostic values as per the 2017 ICG were 78.9%, 42.3%, 60.0%, and 64.7% for Se, Sp, PPV, and NPV, respectively. The CH-EUS incorporation ICG plan improved the malignancy diagnostic values (Se 78.9%/Sp, 53.8%/PPV, 65.2%/NPV 70.0%). CH-EUS may be useful in determining the appropriate treatment strategies for IPMN.

Abstract Background Superior labral anterior to posterior (SLAP) lesions remain a clinical and diagnostic challenge in routine (non-arthrographic) MR examinations of the shoulder. This study prospectively evaluated the ability of 3D-Multi-Echo-Data-Image-Combination (MEDIC) compared to that of routine high resolution 2D-proton-density weighted fat-saturated (PD fs) sequence using 3 T-MRI to detect SLAP lesions using arthroscopy as gold standard. Methods Seventeen consecutive patients (mean age, 51.6 ± 14.8 years, 11 males) with shoulder pain underwent 3 T MRI including 3D-MEDIC and 2D-PD fs followed by arthroscopy. The presence or absence of SLAP lesions was evaluated using both sequences by two independent raters with 4 and 14 years of experience in musculoskeletal MRI, respectively. During arthroscopy, SLAP lesions were classified according to Snyder’s criteria by two certified orthopedic shoulder surgeons. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 3D-MEDIC and 2D-PD fs for detection of SLAP lesions were calculated with reference to arthroscopy as a gold standard. Interreader agreement and sequence correlation were analyzed using Cohen’s kappa coefficient. Figure 1 demonstrates the excellent visibility of a proven SLAP lesion using the 3D-MEDIC and Fig. 2 demonstrates a false-positive case. Results Arthroscopy revealed SLAP lesions in 11/17 patients. Using 3D-MEDIC, SLAP lesions were diagnosed in 14/17 patients by reader 1 and in 13/17 patients by reader 2. Using 2D-PD fs, SLAP lesions were diagnosed in 11/17 patients by reader 1 and 12/17 patients for reader 2. Sensitivity, specificity, PPV, and NPV of 3D-MEDIC were 100.0, 50.0, 78.6, and 100.0% for reader 1; and 100.0, 66.7, 84.6, and 100% for reader 2, respectively. Sensitivity, specificity, PPV, and NPV of 2D-PD fs were 90.9, 83.3, 90.9, and 83.3% for reader 1 and 100.0, 83.3, 91.7, and 100.0% for reader 2. The combination of 2D-PD fs and 3D-MEDIC increased specificity from 50.0 to 83.3% for reader 1 and from 66.7 to 100.0% for reader 2. Interreader agreement was almost perfect with a Cohen’s kappa of 0.82 for 3D-MEDIC and 0.87 for PD fs. Conclusions With its high sensitivity and NPV, 3D-MEDIC is a valuable tool for the evaluation of SLAP lesions. As the combination with routine 2D-PD fs further increases specificity, we recommend incorporation of 3D-MEDIC as an additional sequence in conventional shoulder protocols in patients with non-specific shoulder pain.

ABSTRACT Cholestasis jaundice results from diminished bile flow and/or excretion, and caused by a number of disorders such as biliary atresia (BA). Magnetic resonance cholangiopancreatography (MRCP) is widely accepted as one of the modalities for biliary system imaging; however, liver biopsy still generally used for BA diagnosis, especially in developing countries. This aim study was to evaluate the diagnostic value of biliary atresia from MRCP compared to the result of a liver biopsy. A cross-sectional for diagnostic study documented of hospitalized patients from June 2014 to June 2015. All patients had MRCP and liver biopsy examination. The collection of data including age, gender, clinical manifestation and the result of MRCP and liver biopsy with ROC to evaluate the sensitivity and specificity was done. Liver biopsy revealed of biliary atresia was made based on proliferation, degeneration, and fibrosis of bile ducts. ROC to evaluate the sensitivity and specificity was done. The sensitivity, specificity, negative predictive value, positive predictive value of MRCP in diagnosing BA were calculated. There were 16 patients enrolled in this study with a median age of diagnosis was 6 months old (range 3-11). There were nine female patients out of the 16 patient. The median age of jaundice onset was 5 days (range 2-14 days). All patients had hepatomegaly and splenomegaly. Histopathology from liver biopsy revealed biliary atresia in 12 patients. From the ROC curve, the sensitivity of MRCP was 87.5% and specificity 62.5% with PPV 70% and NPV 80%. Five patients underwent a Kasai procedure and revealed biliary atresia. MRCP is sensitive but not specific for diagnosing BA, and MRCP has moderate sensitivity and specificity for BA diagnosis.Keyword: biliary atresia, magnetic resonance cholangiopancreatography, liver biopsy, diagnostic test.Correspondence: [email protected] ABSTRAKIkterus dikarenakan kolestasis terjadi akibat berkurangnya aliran empedu dan/ atau ekskresi, dan dapat disebabkan oleh sejumlah gangguan seperti atresia biliaris (BA).

213 Background: For planning salvage procedures in recurrent prostate cancer accurate diagnostic tools are needed. Till now in patients suspicious for isolated local recurrent cancer invasive biopsy was needed. 68-Ga-PSMA-PET is frequently used to identify even small metastatic deposits. We analyzed the diagnostic value to identify local recurrence in patients after radiotherapy undergoing salvage radical prostatectomy, sRPE. Methods: We retrospectively reviewed patients undergoing sRPE with 68-Ga-PSMA-PET as preoperative staging. All patients underwent sRPE and extended lymph node dissection. Sensitivity, Specificity, pos and neg predictive value had been calculated per patient and per prostate lobe. Results: 37 patients with preoperative 68-Ga-PSMA-PEt could be identified. In all but one at least in one lobe PSMA staining could be identified. Mean tumor volume per prostate lobe was 6.22 (0.1-24)ml. Sensitivity, Specificity, neg and pos predictive value per lobe is 80%, 75%, 32% and 96%. Sensitivity to identify cancer recurrence per person irrespective of the side is 95% with a pos predictive value of 100%. Conclusions: 68-Ga-PSMA-PET seems to have a very high diagnistic value to identify local recurrence after radiotherapy. After validation of our experience an invasive biopsy to proof cancer recurrence might be spared.

Background Congenital heart disease (CHD) in children requires attention from medical practitioners, because CHDs that are diagnosed early and treated promptly have good prognoses. Ventricular septal defect (VSD) is the most common type of congenital heart disease. Objective To compare the accuracy of electrocardiography (ECG) to echocardiography in diagnosing VSD. Methods This diagnostic study was conducted from November 2013 until July 2015. It involved patients with acyanotic CHDs who were suspected to have VSD at Dr. Wahidin Sudirohusodo Hospital, Makassar, South Sulawesi. Results Of 114 children screened, 97 were included and analyzed. The frequency of positive VSD was 69.1% based on ECG, and 99% based on echocardiography. There was a significant difference between ECG and echocardiography (P=0.000). However, when small VSDs were excluded, there was no significant difference between the two diagnostic tools [(P=1.000), Kappa value was 0.66, sensitivity was 98.5%, specificity was 100%, positive predictive value (PPV) was 100%, and negative predictive value (NPV) was 50%]. Conclusion There were significant differences between the ECG and echocardiography, for diagnosing VSD. However, if small VSDs were not included in the analysis, there was no difference between the two examinations, suggesting that ECG might be useful for diagnosing VSD in limited facilities hospitals.

Abstract Background Postoperative surgical site infections (SSIs) are a common complication of surgical procedures; however, the use of drain tip cultures to diagnose SSIs in patients is controversial. The objective of this study was to evaluate the efficacy of drain tip cultures for the prediction of postoperative SSIs in patients recovering from hip arthroplasty. Methods The data was compiled from 1,204 patients over a 15-year period. Statistical analysis was performed to evaluate the diagnostic value of drain tip culture in determining surgical site infection. We also used this data to evaluate whether preexisting conditions such as hypertension or diabetes affected the probability of a patient getting an SSI. Results Drain tip cultures were positive in 12 of 1,112 cases of primary hip arthroplasty, but only one of these 12 patients were ultimately diagnosed with an SSI (sensitivity, 12.5%; specificity, 99.0%; p = 0.0834). Results from postoperative drain tip cultures performed in patients undergoing revision arthroplasty included two false positives and three false negatives; interestingly, no true positives were detected in any of the revision arthroplasty cases we evaluated (sensitivity, 0%; specificity, 97.8༅; p = 0.9355). Conclusions Our results indicate that drain tip cultures have no statistically significant predictive value for the diagnosis of post-operative SSIs and thus should not be used as a primary diagnostic or predictive tool for SSIs. We recommend that other diagnostic tools for the postoperative diagnosis of SSIs be explored. Standardized guidelines should therefore be established to improve the predictive value of alternative methods.

Molecular testing is rapidly becoming an integral component of global tuberculosis (TB) control. Uncommon mechanisms of resistance escape detection by these platforms and undermine our ability to contain outbreaks. This article is a systematic review of published articles that reported isoniazid (INH) resistance-conferring mutations between September 2013 and December 2019. The genes katG, inhA, fabG1, and the intergenic region oxyR’-ahpC were considered in this review. Fifty-two articles were included describing 9,306 clinical isolates (5,804 INHR, 3,502 INHS) from 31 countries. The three most frequently mutated loci continue to be katG315 (4,271), inhA-15 (787), and inhA-8 (106). However, the diagnostic value of inhA-8 is far lower than previously thought, only appearing in 25 (0.4%) INHR isolates lacking the first two mutations. We catalogued 45 new loci (29 katG, nine inhA, seven ahpC) associated with INH resistance and identified 59 loci (common to this and previous reviews) as a reliable basis for molecular diagnostics. Including all observed mutations provides a cumulative sensitivity of 85.6%. In 14.4% of resistant isolates no mechanism of resistance was detected, making them likely to escape molecular detection, and in case of mono INH resistance likely to convert to MDR-TB. Integrating the information cataloged in this study into current diagnostic tools is essential for combating the emergence of MDR-TB, and its exclusion can lead to an unintended selection against common mechanisms and to diversifying evolution. Observation of many low-frequency resistance-conferring mutations points to an advantage of WGS for diagnostics. Finally, we provide five recommendations for future diagnostic platforms.

Background: The incidence of Placenta Accreta Spectrum Disorders (PASD) increases by 10-fold in 50 years along with the number of cesarean sections. Ultrasound examination using Placenta Accreta Index (PAI) score and Placenta Accreta Spectrum (PAS) stage as a predictor of PASD has been used worldwide at the antenatal screening. The high diagnostic value of these tools will help the physician to diagnose PASD early and minimize the rate of maternal neonatal mortality and morbidity. Objectives: To evaluate the value of PAI score and PAS stage in diagnosing PASD. Methods: This study is a diagnostic test study using the medical records of mothers who gave birth at Haji Adam Malik General Hospital Medan Indonesia between September 2017 to September 2020, who were diagnosed preoperatively as placenta previa suspected PASD through ultrasound examination using PAI score or PAS stage. The results of these two diagnostic tests were compared to clinical diagnostic criteria of PASD from The International Federation of Obstetrics and Gynecology (FIGO) with or without histopathological confirmation. Results: Of the 177 placenta previa cases, there were 142 women with PASD (80.2%). The diagnostic values of PAI score with 4.6 as an optimal cut-off point were 75% sensitivity, 83% specificity, 94% positive predictive values (PPV), and 47% negative predictive values (NPV). The diagnostic values of the PAS stage were 90% sensitivity, 83%, specificity, 96% PPV, and 68% NPV. Conclusion: PAI score and PAS stage have a diagnostic value that looks equally good when used as a diagnostic tool for PASD.

Background: Different diagnostic tools are available to evaluate endometrial lesion such as hysteroscopy, sonohysterography and transvaginal ultrasound. The present study aimed to determine the diagnostic value of saline infusion sonohystrography (SIS) in diagnosis of intrauterine lesions in women with postmenopausal bleeding (PMB).Methods: This cross-sectional study recruited 100 married women with chief complain of PMB referred to gynecologic clinics at the Zenana hospital, Jaipur from March 2019 to February 2020. All participants were in the post-menopausal period that showed abnormal endometrial thickness (>4 mm) or endometrial focal lesions through transvaginal ultrasound. Participants underwent SIS, hysteroscopy plus endometrial biopsy in order. The gold standard was the histopathology of endometrial specimen reported by pathologist.Results: Mean age of women was 57.14 years. It is evident that sensitivity, specificity, positive predictive value and negative predictive value of SIS for the diagnosis of endometrial atrophy was 79.16%, 100%, 100% and 83.87% respectively which is higher than that of hysteroscopy and equivalent to histopathology. SIS and hysteroscopy are equally efficient in diagnosing endometrial polyp and submucous fibroid. And are better than histopathology. Histopathology is better than SIS and hysteroscopy for the diagnosis of endometrial proliferation.Conclusions: Findings show that, SIS probably is a proper method for detecting endometrial focal lesion including polyps and myomas. Future studies may help to define further advantages of this procedure.
