Evaluation of the systemic-immune inflammation index (SII) and systemic immune-inflammation response index (SIRI) in children with type 1 diabetes mellitus and its relationship with cumulative glycemic exposure.

OBJECTIVES: In this study, the systemic proinflammatory status was assessed using the systemic immune-inflammation index (SII) and SIRI systemic immune-inflammatory response index (SIRI) in children and adolescents with type 1 diabetes mellitus (T1DM). METHODS: The study involved 159 patients aged between 6 and 16 years. The SII and SIRI values were calculated based on the complete blood count. Basic blood biochemistry evaluated, and carotid intima-media thickness (cIMT) was measured and recorded. The cumulative glycemic exposure was calculated by multiplying the value above the normal reference range of the HbA1c value. The sum of all these values obtained from the time of diagnosis to obtain the cumulative glycemic exposure. All findings were compared statistically. All statistically significant parameters were evaluated in the multivariate logistic regression analysis. RESULTS: The analysis revealed that only cIMT (Exp(B)/OR: 0.769, 95 % CI: 0.694-0.853, p<0.001), high-density lipoprotein (Exp(B)/OR: 3.924, 95 % CI: 2.335-6.596, p<0.001), monocyte count (Exp(B)/OR: 1.650, 95 % CI: 1.257-2.178, p<0.001), hematocrit (Exp(B)/OR: 0.675, 95 % CI: 0.523-0.870, p<0.001), and SIRI (Exp(B)/OR: 1.005, 95 % CI: 1.002-1.008, p<0.001) were significantly associated with T1DM. A statistically significant positive association was found between cumulative glycemic exposure and SIRI only (r=0.213, p=0.032). To our knowledge, this is the first study to evaluate SII and SIRI in children with type 1 diabetes. CONCLUSIONS: These findings indicate that SIRI could serve as a potential biomarker for detecting early-onset proatherosclerotic processes in diabetic children. However, further clinical studies are required to confirm this.

Detection of the glenoid bare spot by non-arthrographic MR imaging, conventional MR arthrography, and 3D high-resolution T1-weighted VIBE MR arthrography: comparison with CT arthrography.

OBJECTIVES: To determine the diagnostic accuracy of non-arthrographic MR imaging, conventional MR arthrography, and 3D T1-weighted volumetric interpolated breath-hold examination (VIBE) MR arthrography sequences as compared with a CT arthrography in the diagnosis of glenoid bare spot. METHODS: A retrospective study of 216 patients who underwent non-arthrographic MR imaging, conventional MR arthrography, VIBE MRI arthrography, and CT arthrogram between January 2011 and March 2022 was conducted. The diagnostic accuracy of non-arthrographic MR imaging, direct MR arthrography, and VIBE MRI arthrography in the detection of glenoid bare spot was compared with that of CT arthrography. All studies were reviewed by 2 MSK radiologists. Interobserver agreement for MR imaging and MR arthrographic findings was calculated. RESULTS: Sixteen of 216 patients were excluded. Twenty-three of 200 shoulders had glenoid bare spot on CT arthrographic images. The glenoid bare spot was detected in 11 (47.8%) and 7 (30.4%) patients on conventional non-arthrographic MR images and in 18 (78.3%) and 16 (69.6%) patients on conventional MR arthrograms by observers 1 and 2, respectively. Both observers separately described the bare spot in 22 of 23 patients (95.7%) on 3D volumetric MR arthrograms. Interobserver variabilities were fair agreement for conventional non-arthrographic MR imaging (κ = 0.35, p < 0.05), moderate agreement for conventional MR arthrogram (κ = 0.50, p < 0.05), and near-perfect agreement for 3D volumetric MR arthrogram reading (κ = 0.87, p < 0.05). CONCLUSIONS: A 3D high-resolution T1-weighted VIBE MR arthrography sequence may yield diagnostic performance that is comparable with that of CT arthrography in the diagnosis of glenoid bare spot. KEY POINTS: •Glenoid bare spot should not be misdiagnosed as a transchondral defect of the glenoid surface by radiologists. •A 3D high-resolution T1-weighted VIBE MR arthrography sequence may be used as a high-sensitivity imaging technique in the diagnosis of glenoid bare spot.

The association between the renal resistive index and the myocardial performance index in the general population.

OBJECTIVE: The renal resistive index (RRI) is the most described measure of renal hemodynamics. The myocardial performance index (MPI) is widely used to assess overall myocardial performance. In this study, we aimed to investigate the relationship between renal hemodynamics, assessed by the RRI, and cardiac functions, assessed by the MPI in the general population. METHODS: This single-center, cross-sectional study included a total of 302 consecutive patients who presented to our outpatient cardiology clinic between October 2019 and February 2020. All patients underwent transthoracic echocardiography and renal Doppler ultrasonography. The study population was divided into two groups: low RRI group (RRI ≤ 0.7, n = 236) and high RRI group (RRI > 0.7, n = 66). RESULTS: E/A ratio, left ventricular ejection fraction (LVEF), and the MPI were significantly higher in the high RRI group than in the low RRI group (61.3 ± 15.4 vs 55.3 ± 16.4, P = .010 for E velocity; 0.9 ± 0.3 vs 0.7 ± 0.2, P = .008 for E/A ratio; 57.7 ± 4.7 vs 53.2 ± 10.1, P = .029 for LVEF; 0.52 ± 0.1 vs 0.43 ± 0.1, P < .001 for the MPI). A stepwise linear regression analysis demonstrated that LVEF (ß = .123, P = .026), E velocity (ß = .221, P < .001), and the MPI (ß = .392, P < .001) were independently associated with the RRI. CONCLUSION: Left ventricular ejection fraction and intra-cardiac Doppler blood flow indices, including E velocity and the MPI, were significantly and independently associated with the RRI in the general population.

Lumbar Morel-Lavallee lesion after trauma: a report of 2 cases.

Morel-Lavallee syndrome is a posttraumatic soft tissue injury in which the subcutaneous tissue is broken off from the underlying fascia, creating a cavity filled with hematoma and liquefied fat. It commonly occurs over the greater trochanter and, rarely, may also occur in the lumbal region.Morel-Lavallee syndrome can be often diagnosed late because of ommitted diagnosis in emergency services. The emergency physician and radiologist must keep this syndrome in mind because early diagnosis can enable conservative management, whereas delayed diagnosis may lead to surgical exploration. In this article,we present the clinical and radiologic features of 2 cases of lumbar Morel-Lavallee syndrome detected after trauma.

Colloid cyst mimicking intracranial hemorrhage after head trauma.

Trauma patients consist vast majority of the patients who admit to emergency department, and most of them have a head trauma. A 58-year-old patient was taken to emergency department with head trauma, and a hyperdense lesion neighboring to third ventricle was detected. A diagnosis of colloid cyst was made in the patient who was being followed up for hemorrhage. In patients with head trauma, colloid cyst may easly be confused with intracranial hemorrhage due to hyperdensity. The aim of this report is to emphasize the importance of clinical thinking in the differential diagnosis of hyperdense lesion on computed tomography imaging of a patient with head injury.
