Association between mesenteric panniculitis and urolithiasis.

BACKGROUND: Mesenteric panniculitis is a rare condition and refers to benign and nonspecific inflammation of mesenteric fat. OBJECTIVES: This study aimed to evaluate the hypothesis of a greater prevalence of mesenteric panniculitis in patients with urolithiasis. MATERIALS AND METHODS: In this cross-sectional study, abdominopelvic CT scans of 500 patients were reviewed for the presence of urolithiasis and mesenteric panniculitis. The inclusion criteria were patients who were referred with acute abdominal pain and were suspected of having urolithiasis or other urinary conditions and who had undergone abdominopelvic CT scan. Subcutaneous fat thickness was measured, and pain intensity was recorded by patient evaluation. RESULTS: Mesenteric panniculitis was found in 10 patients, all of whom (100%) had urinary stones (ureter or kidney or both), and none of them had previous surgeries or known malignancies. The prevalence of panniculitis was significantly greater in the group with urolithiasis. In the urolithiasis group, subcutaneous fat thickness was greater in patients with panniculitis, although the difference was not statistically significant. In the subgroup analysis, pain intensity was not significantly greater in patients with panniculitis. CONCLUSION: Mesenteric panniculitis is more prevalent among patients with urolithiasis, but it seems that it does not change the intensity of the pain.

Effect of Silybum Marianum on Reduction of Chemotherapy-Induced Peripheral Neurotoxicity with Cisplatin.

Background: Chemotherapy-induced peripheral neurotoxicity (CIPN) is one of the major complications of chemotherapy regimens commonly used in the treatment of solid and hematologic cancers. Given the high incidence of CIPN in antitumor therapies in patients and limited studies on antioxidants, this study was aimed to investigate the effect of Silybum marianum (SM) on cisplatin-induced peripheral neuropathy. Materials and Methods: This double-blind randomized clinical trial study was performed on 60 cancer patients treated with cisplatin chemotherapy at Seyyed-o-Shohada Hospital of Isfahan during 2019-2020. The patients were divided into two parallel groups as intervention (treated by SM) and placebo, and DN4 (Douleur neuropathique 4 questions) and CIPNAT (chemotherapy-induced peripheral neuropathy assessment tool) were completed for patients in the before and after intervention groups and compared between the two groups. Results: The mean of DN4 score in the before and after study in the intervention group was in 1.76 ± 1.24 and 2.07 ± 2.03, respectively (P = 0.38), and in the control group was 1.41 ± 1.28 ± 3.11 ± 2.86, respectively (P = 0.012). The mean CIPNAT score in the intervention groups was 5.93 ± 3.65 and 4.20 ± 3.23 (P = 0.01), and in the control group was 4.20 ± 4.22 and 4.16 ± 4.03 (P = 0.39). Conclusion: Based on our data, SM is an effective agent in reducing peripheral neuropathy. The use of SM was associated with decreased scores of peripheral neuropathy and was helpful in patients undergoing chemotherapy with cisplatin.

Exceedingly rare incidence of a double inferior vena cava (IVC) with azygos continuation of left IVC.

Key Clinical Message: Because of the complex embryonic origin of the abdominal venous structures, IVC and azygous systems can show numerous and even previously unreported anatomical variations and anomalies. Also, evaluating major vascular structures should not be dismissed in non-contrast-enhanced CT as it can provide valuable information about these structures. Abstract: Double IVC is a rare occurrence of IVC anatomical variations and congenital anomalies. Herein, we discuss a case of a very rare type of double IVC that has not been reported in the literature before. A non-contrast-enhanced CT study was performed for a 34-year-old patient who visited our ER to evaluate for urolithiasis, during which two IVCs were noted. Each renal vein joined the ipsilateral IVC at a perpendicular angle. Unusually, the right IVC was formed from the confluence of both left and right common iliac veins (CIV), and the left IVC-Instead of crossing the midline at the renal veins level and reuniting the right IVC-cranially contributed to the azygos vein formation and caudally joined the left CIV. Also, there were some small communicating veins between the two IVCs and the left gonadal vein was slightly dilated before suggesting a reflux from the left renal vein (LRV). A complimentary doppler ultrasound exam confirmed the diagnosis and revealed a left-side varicocele. Although rare cases of hemiazygos continuation and interiliac connections of left-side IVC in the cases of double-IVC have been reported previously, a complete confluence of CIVs is rare. The main differential diagnosis is retro-aortic left renal vein (RLRV) type IV which seems to have an oblique course. Radiologists and surgeons should expect previously unreported variations in the vena cava system. Furthermore, reviewing the main abdominal vasculature should not be dismissed in non-contrast CT exams.

A case report of eosinophilic jejunal enteritis with spared stomach presenting as abdominal pain.

Eosinophilic gastroenteritis (EoGE) is a group of infrequent conditions that arise from the accumulation of eosinophils in the gastrointestinal (GI) tract without any secondary causes of eosinophilia. Most cases of EoGE cases show involvement of different parts of the GI tract. Herein, we report a case of EoGE with the sole involvement of Jejunum. A 57-year-old male patient presented to our center with a chief complaint of acute abdominal pain. The patient had experienced chronic abdominal pain and intermittent diarrhea for several years, but he presented to the emergency department with severe acute flank pain. The patient was first diagnosed with renal stone and treated accordingly. However, the computed tomography (CT) scan also showed other incidental findings related to his chronic abdominal pain from several years ago, including mesenteric infiltration which shows fluid appearance in some areas, mild wall thickening, and mucosal edema of the duodenum and jejunal loops with normal appearance of the ileum. Complete blood count (CBC) showed increased eosinophil (15.5%) and decreased lymphocytes (13.1%) percent. Pathological examination of enteroscopy samples of jejunum showed a mild increase in the number of eosinophils in lamina propria. Neither parasites nor granuloma was detected. However, no such changes were found in other parts of the GI tracts. Based on pathological examination, the patient was diagnosed with eosinophilic enteritis of the jejunum. EoGE does not typically involve a specific part of the GI and generally affects both the stomach and intestine. This study reported the first case of EoGE where only the jejunal part of the intestine was involved and other parts of the GI tract were spared.

Assessment of renal transplant dysfunction by doppler sonography: A systematic review and meta-analysis.

Background: Doppler sonography parameters, particularly the resistive index (RI), have been identified as an essential tool for assessing renal transplant dysfunction (RTD). However, there is some ambiguity in the findings of previous research studies on this matter. Therefore, the objective of our study is to examine the relationship between changes in RI subsequent to RTD. Methods: This was a systematic review and meta-analysis study. We searched three electronic databases PubMed, Web of Science, and Scopus, from the year 2000 to 10 May 2022. The main effect size was considered as the mean RI differences of cases with RTD confirmed by biopsy with control patients with no RTD. We used random effect models to pool the effect size. Results: Thirteen studies were included in our review. The pooled mean (95% CI) for the control group was calculated to be 0.71 (0.67, 0.75) and for patients with renal transplant dysfunction was 0.73 (0.68, 0.78), under a random effect model with high heterogeneity for both analyses (I2=98% and 97%, respectively). The pooled mean was significantly different between the control group and patients with RTD (P= 0.05), based on a t-test of pooled effect sizes. Conclusions: Based on the result of our study, we showed that there is a significant difference between RI in patients with kidney transplant dysfunction and the control group. However, RI cannot substitute kidney biopsy in the management and diagnosis of RTD.

Essential thrombocythemia associated with fibrosis involving bilateral renal sinuses: A case report.

Essential thrombocythemia (ET) is associated with an increased risk of thrombosis and autoimmune renal involvement. We report an extremely rare case of an acute kidney injury (AKI) in the presence of bilateral renal pelvises fibrosis in a patient with a proven diagnosis of ET. A 48-year-old male patient with a past medical history of mild chronic kidney disease and ET was admitted to our hospital with AKI. The patient discontinued his hydroxyurea treatment for the past 2 months and laboratory data showed increasing serum creatinine levels and platelet counts with increased renal sizes, severe hydrocalyx, and bilateral renal sinuses' fibrosis in imaging. The patient started again on hydroxyurea therapy and showed improvement in all laboratory scales. ET and increased levels of platelet-derived growth factors could cause renal sinuses fibrosis and glomerulopathy. In ET patients with renal sinuses' fibrosis and glomerulopathy, initiating cytoreductive therapy could improve the outcome.

Relationship between the severity of endometriosis symptoms (dyspareunia, dysmenorrhea and chronic pelvic pain) and the spread of the disease on ultrasound.

OBJECTIVES: About 10-15% of women of childbearing age have endometriosis. The present study aimed to investigate the relationship between the severity of symptoms of endometriosis and the spread as well as the stage of the disease on ultrasonography. The present cross-sectional study evaluates the relationship between the severity of endometriosis symptoms and the spread of disease on ultrasonography in patients with endometriosis. RESULTS: Considering different analyses, the cumulative size of posterior deep infiltrative endometriosis (DIE) (less than 1 cm) is significantly correlated with minimal severity of dyspareunia and chronic pelvic pain. The incidence of dyspareunia was more prevalent in patients with complete stenosis of Douglas pouch than those with incomplete stenosis. Furthermore, the incidence of severe and very severe pain in patients with Douglas pouch stenosis is relatively higher than that in patients without stenosis. Only dyspareunia is related to the stage of endometriosis, and patients with dyspareunia are five times more at risk of a higher stage of the disease. The severity of dyspareunia is related to the stage of endometriosis and the severity of Douglas pouch stenosis. The results showed a correlation between chronic pelvic pain and r-ASRM score (revised American Society for Reproductive Medicine score).

Neurobrucellosis in a 9-year-old girl.

Brucellosis is a zoonotic multi-organ infectious disease most frequent in developing countries. Neurobrucellosis a quite rare but serious complication of brucellosis in the pediatric age group manifests with different neurological symptoms and signs. In the present case a 9-year-old girl was referred to our centre with a 9-months history of headache and back pain, facial nerve palsy and right upper limb weakness. She had undergone ventriculoperitoneal shunting surgery due to communicating hydrocephalus. Magnetic resonance imaging revealed a spinal extramedullary intradural mass, two epidural collections in the cervical spine and thickening/abnormal enhancement in the basal cisterns with invasion to medulla and pons. The patient's serum and cerebrospinal serologic tests were found positive for brucellosis. The patient was successfully treated by anti-brucella antibiotic therapy.

The Effects of Synbiotic Supplementation on Metabolic Status in Women With Polycystic Ovary Syndrome: a Randomized Double-Blind Clinical Trial.

Data on the effects of synbiotic supplementation on glycemic control, lipid profiles, and atherogenic index of plasma (AIP) of women with polycystic ovary syndrome (PCOS) are limited. The purpose of this study was to assess the effects of synbiotic supplementation on glycemic control and lipid profiles in women with PCOS. A prospective, randomized, double-blind, placebo-controlled trial was done at the Naghavi Hospital affiliated to Kashan University of Medical Sciences, Kashan, Iran, between April 2017 and June 2017. Sixty women with PCOS were randomized to intake synbiotic capsule containing Lactobacillus acidophilus strain T16 (IBRC-M10785), Lactobacillus casei strain T2 (IBRC-M10783), and Bifidobacterium bifidum strain T1 (IBRC-M10771) (2 × 109 CFU/g each) plus 800 mg inulin (n = 30) or placebo (n = 30) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to determine related variables. Compared with the placebo, synbiotic supplementation resulted in a significant reduction in serum insulin concentrations (- 2.8 ± 4.1 vs. + 1.8 ± 6.4 µIU/mL, P = 0.002) and homeostasis model of assessment-insulin resistance (- 0.7 ± 1.0 vs. + 0.4 ± 1.5, P = 0.002), and a significant elevation in the quantitative insulin sensitivity check index (+ 0.01 ± 0.01 vs. - 0.01 ± 0.03, P < 0.001). In addition, significant decreases in serum triglycerides (- 16.2 ± 31.4 vs. + 5.8 ± 23.1 mg/dL, P = 0.003), VLDL-cholesterol concentrations (- 3.3 ± 6.3 vs. + 1.1 ± 4.6 mg/dL, P = 0.003), and AIP (- 0.05 ± 0.08 vs. - 0.003 ± 0.10 mg/dL, P = 0.03) were seen following the supplementation of synbiotic compared with the placebo. Overall, we found that synbiotic supplementation to women with PCOS for 12 weeks had beneficial effects on markers of insulin resistance, triglycerides, VLDL-cholesterol concentrations, and AIP, but did not influence other lipid profiles.
