Objective: Lesion detection at contrast material-enhanced breast Magnetic Resonance (MR) imaging is primarily based on a lesion's vascularity relative to normal breast tissue. MR imaging may be still be advantageous because it can be used not only to characterize the lesion in question but also to evaluate the remainder of the breast, potentially leading to identification of unsuspected multifocal disease. The primary benefit of a noninvasive test such as MR imaging undertaken prior to tissue diagnosis (ie, with core biopsy or excisional biopsy) is that it can be used to determine which lesions are likely to be benign, so that mammographic or clinical followup could be used in place of tissue diagnosis. When a test is used in this capacity, it must be sufficiently sensitive that the negative predictive value is very high without sacrificing specificity. Standard evaluation criteria have not been optimized for evaluating 

Sjӧgren's syndrome (SS) is a systemic autoimmune disease affecting mainly the exocrine glands. Tubulointerstitial nephritis (TIN) is the most predominant renal involvement with lymphocyte and plasma cells
infiltration of the interstitium. We report a case of young female with SS presented with renal tubular acidosis (RTA), polyradiculoneuropathy &proteinuria. Renal biopsy revealed granulomatous interstitial nephritis. Granuloma formation is rarely seen in cases of SS.

Background and objectives Despite much research about lupus nephritis, none of the urinary biomarkers has been proven to be truly reflecting lupus nephritis activity, response to treatment, or prognosis. We aimed to study urinary biomarkers in lupus nephritis and test the r relation to kidney damage.
Patients and methods: Forty patients with systemic lupus erythematosus (SLE) were divided into two groups: (1) lupus nephritis group with biopsy-proven proliferative lupus nephritis (classes III and IV) and who did not receive immunosuppressive drugs within the preceding 3 months except for glucocorticoids and (2) lupus non-nephritis group with SLE patients without any renal manifestation. We assessed disease activity by the SLE disease activity index. uNGAL, uKim-1, uNGAL to urinary creatinine excretion (mg/dl), and uKim-1 to urinary creatinine excretion were measured in random spot urine samples at the time of renal biopsy and 6 months after the induction therapy.
Results The LN group before treatment showed higher levels of uNGAL and uKIM-1 (P-value < 0.001). ROC analysis showed that uNGAL at level of > 59 has a 95 % sensitivity, a 100 % specificity, and an AUC = 0.996 in the ability to diagnose LN. While the uKIM-1 ROC showed that at level of > 1.6, it has an 85 % sensitivity, an 80 % specificity, and an AUC = 0.919. uNGAL and uKIM levels were significantly lower after treatment (P-value < 0.001). No significant correlations were found between urinary markers before and after treatment with other clinical, inflammatory, and serological markers of lupus nephritis.
Conclusion uNGAL, uKIM, uNGAL/Creat ratio, and uKIM/Creat ratio can be used as a predictor and a marker of disease activity for lupus nephritis.

Objective
To compare echocardiography‑guided versus clinically guided fluid resuscitation regarding mortality of critically ill patients in ICU.
Patients and methods
This randomized controlled trial was carried out on 120 patients with circulatory shock. Demographic, clinical, and routine laboratory data were recorded. Eligible patients were randomly assigned to either echocardiography‑guided fluid resuscitation or clinically guided fluid resuscitation. Fluid responsiveness was defined as either left ventricular outflow tract‑time velocity integral respiratory variation by 12% or an increase in left ventricular outflow tract‑time velocity integral by 12% after 250 ccs of normal saline challenge.
Results
Echocardiography‑guided resuscitation cases have significantly lower hospital mortality (30 vs. 43% in controls; P = 0.001), intubation and mechanical ventilation rates (7.87 ± 0.63 vs. 4.48 ± 0.38 days in controls; P = 0.01). Moreover, cases have a significantly lower amount of fluid (26 800 vs. 50502 ml in the control group20), with significantly lower net cost [13.4$ (214 EGP) vs. vs 25.11 $ (401 EGP) in the controls; P = 0.000 in controls; P = 0.00].
Conclusions
Echocardiography‑guided fluid resuscitation appears to have lower hospital mortality, hospital morbidities, and ICU cost.

Previous trials evaluated the incidence of critical illness–related corticosteroid insufficiency (CIRCI)
using 250 μg adrenocorticotropic hormone (ACTH). However, this supraphysiological dose could result in false-positive levels.
We aimed to determine the incidence of CIRCI in septic patients using a 1 μg ACTH stress test. Methods: We conducted a prospective cohort study on 39 patients with septic shock. Critical illness–related corticosteroid insufficiency was defined as a Δ max cortisol <9 μg/dL after 1 μg ACTH stress test. The primary outcome of the study was death. Secondary outcomes included days of vasopressors, days of mechanical ventilation (MV), amount of fluid per day, the incidence of acute kidney injury (AKI), and days of intensive care unit (ICU) stay. Results: The incidence of CIRCI in our cohort was 43.6%using 1 μg ACTH. There were no significant differences between groups in terms of ICU scores, laboratory investigations, vasopressors, MV days, amount of
fluid per day, and the ICU stay (P = > 0.05). The CIRCI group had lower median survival and survival probability rates (5 days and 48.4%, respectively) compared with the non-CIRCI group (7 days and 49.5%, respectively). In addition, the CIRCI group had a shorter time to develop AKI and a higher probability of developing AKI (4 days and 44.6%, respectively) in comparison with the non-CIRCI group (6 days and 45.57%, respectively). Conclusion: We concluded that the CIRCI group had a lower mean survival rate and a higher incidence of AKI. We recommend the use of 1 μg ACTH test in septic shock patients to identify this subgroup of patients.

The respiratory variations in mitral valve (MV) Doppler flow in hemodialysis (HD) patients have not been investigated and the normal echocardiographic value is used as a reference for HD patients. The present study evaluated the respiratory variation in MV Doppler flow in HD patients to determine if it has a unique pattern. In this prospective cohort study, echocardiography was performed before and 6 h after dialysis. The transmitral spectral Doppler E wave was measured during inspiratory and expiratory phases. The percent changes in the E wave were calculated pre- and post-dialysis. The means of the percent variation in the MV inspiratory and expiratory E wave pre- and post-dialysis were 56 ± 7% and 44 ± 1.1%, respectively, with a significant
reduction after dialysis (P = .000). There was a significant positive correlation between post-dialysis ΔE wave % change and postdialysis % change in weight (r = .318; P = .000). The respiratory changes in the MV E wave in HD patients were higher than the normal reference values. This marked variation could be explained by fluid overloading in HD patients.
