Abstract Background and Aims COVID-19 has heterogeneous clinical manifestations. SARS-CoV-2 related AKI and hypercoagulability are negative prognostic factors. The incidence of thromboembolic events is about 30%, of AKI up to 20%. We report a patient with severe AKI who required hemodialysis (HD) and developed a massive DVT developing from the femoral CVC, and belatedly testing positive for SARS-CoV-2 in the absence of typical pulmonary involvement. Method A 53-year-old male with a clinical history of hypertension, type II diabetes mellitus, in therapy with metformin and ace-inhibitor, was admitted to our E.R. with diarrhea, nausea and vomiting for about 2 days. Main signs: ideomotor slowdown, mild hypohydration and reduced urine output (unrelevant sediment). Initial blood tests showed severe AKI with hyperkalemic metabolic acidosis and hyponatremia (sCreatinine 18.76 mg/dl, BUN 161 mg/dl, K+ 7.8 mmol/l, Na+ 128 mmol/L, HCO3- 9.8 mmol/l). Mild neutrophilic leukocytosis with lymphopenia was detected, with slightly increased inflammation indices (CRP 1.05 mg / dl, D-dimer 720 ng / ml). CT scan: absence of typical SARS-CoV-2 signs, normal kidneys, no dilation of urinary tract. SARS-CoV-2 rapid antigen test and the first molecular swab test were negative. After femoral CVC insertion, HD was needed for a few sessions. Broad range antibiotic therapy was also set. On Day 3: a second SARS-CoV-2 PCR swab test resulted negative. He never manifested fever or dyspnea. On Day 6, despite an improvement of renal function (sCr 2.7 mg/dl), the patient, although he walked, presented right leg pain with signs of DVT. Ultrasound and angio-CT scan documented peri-catheter DVT extended to the common femoral and external iliac vein and superficial femoral vein involvement, without pulmonary embolism. I.v. therapy with sodium heparin was therefore started with quite a difficulty in reaching the expected range. On day 8, massive flittene appeared, the CVC was removed and a caval filter was placed; marked neutrophilic leucocytosis and increased inflammatory indices (CRP 11.50 mg/dl) was documented. Nevertheless, thrombosis has progressed to the entire venous axis and the inferior cava. Through a tibial vein introducer local i.v. alteplase was also started. Just after, copious bleeding from the site of the removed CVC followed by haemorrhagic shock occurred and the patient was transferred to the ICU (D-dimer 219800 ng/ml). The same day a third swab for SARS-CoV-2 resulted positive while a further CT-scan did not show signs of virus-like interstitial pneumonia. On the following day (day 9) the patient underwent thrombus aspiration (Aspirex®S device) and fasciotomy of the right leg for a compartment syndrome. Results Despite the continuation of heparin, PTT ratio was never >1.5, with an extension of DVT and also involvement of the contralateral iliac vein, as well as a worsening of the clinical-laboratory picture and patient’s death on day 14. Serum complement, autoantibodies (ANA, ANCA, ENA, ANTI-dsDNA, anti-cardiolipin, AMA, anti-B-glycoprotein) and factor V Leiden test were normal. All blood cultures were found to be sterile. Conclusion Our case confirms the heterogenicity of COVID-19 manifestations, often without pulmonary involvement. According to our experience from the onset of the pandemic, SARS-CoV-2 can also be found later in patients with already advanced organ damage. In this case, in the absence of other possible factors, AKI and intestinal involvement may have been early signs of COVID-19, with a virus initially not detectable in the nasopharyngeal mucosa. Furthermore, the increased thromboembolic risk of COVID-19 should not be underestimated in the presence of risk factors as external devices, also given the difficult management of anticoagulation target. Anticoagulant prophylaxis in cases with doubtful symptomatology and CVC must be considered even in non-bedridden patients, due to the current risk of SARS-CoV-2 infection.

A 38-year-old man with a history of polyposis syndrome diagnosed 3 years previously, with poor compliance for follow-up, presented to the emergency department with symptoms of retrosternal chest pain associated with dizziness and shortness of breath. His blood pressure was 94/43 mm Hg, his pulse was 123 beats/min and he had an oxygen saturation of 84% on room air. The patient’s initial laboratory results showed a hemoglobin of 80 g/L and blood gas with a pH of 7.23. He had a normal chest radiograph and electrocardiogram, but had an elevated troponin I at 0.12 μg/L. He was given acetylsalicylic acid for suspicion of acute coronary syndrome. On physical examination, the patient was found to have right calf tenderness. With this finding and the presenting symptoms, he underwent computed tomography angiography (CTA) of the chest. The chest CTA showed a massive saddle embolus with a filling defect completely occluding the right pulmonary artery and extending through the main pulmonary artery segment to involve the left pulmonary artery. There were also diffuse filling defects involving bilateral pulmonary segmental arteries (Fig. 1 and Fig. 2). The patient received alteplase and underwent a workup for a hypercoagulable state. His workup revealed positive anticardiolipin antibodies and factor V Leiden. The Doppler ultrasound of his lower extremities showed an extensive thrombus measuring more than 6 cm extending in the right superficial femoral vein. The patient was then referred for placement of an inferior vena cava filter.

Abstract OBJECTIVE AND IMPORTANCE: Neurofibromas are benign neural sheath tumors arising from intraneural supporting cells. Such tumors are characteristic of neurofibromatosis Type I (von Recklinghausen disease) but also occur sporadically. Vascular involvement by neurofibromata is rare, but has been described in the past in the context of neurofibromatosis. There is, to our knowledge, no description of vascular involvement by a neurofibroma in a non-neurofibromatosis patient. CLINICAL PRESENTATION: A 40-year-old woman presented with a 4 year history of a right thigh mass associated with diffuse lower extremity pain. She had no other clinical manifestations of neurofibromatosis and no known family member with neurofibromatosis Type I. Magnetic resonance imaging scans revealed a well-defined solid mass in the anteromedial aspect of the right thigh closely associated with the superficial femoral vein. INTERVENTION: The vessel segment and encapsulated mass were resected “en bloc” after proximal and distal ligation of the vein. The pathological appearance of the mass was consistent with a benign neurofibroma that had infiltrated all layers of the vessel. CONCLUSION: Vessel invasion by a benign sporadic neurofibroma is a rare occurrence with potentially severe implications for the patient. It suggests that surgical removal of asymptomatic benign-appearing lesions of that type should be considered if they are adjacent to important anatomical structures.

The novel coronavirus disease 2019 (COVD-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The immunothrombosis could occur during infectionwith viruses. Deep vein thrombosis (DVT) is a devastating condition that usually involves the lower extremities. The typical course of DVT is associated with an episode of enormous limbswelling and pain. In this case report, we aimed to present one of the COVID-19 possible complications: DVT in a 38 years old man infected with SARS-CoV-2. A 38 years old manpresented with leg pain. He had a dry cough and fatigue suspicious symptoms of COVID-19. For further evaluations, the lung Computed Tomography scan (CT-scan), labratoricalassessments, and doppler sonography of the common femoral vein (CFV) of both legs were done. Also, for investigating the other underlying causes of DVT, abdominopelvic CT-scan andlumbosacral Magnetic Resonance Imaging (MRI) were done. The CT-scan showed GroundGlass Opacity (GGO) view. Labratorical assessment proposed a thrombotic condition. Thedoppler sonography of the CFV of both legs revealed a massive thrombosis in the left CFV suggesting an acute DVT. Abdominopelvic CT-scan and lumbosacral MRI were negativefor other underlying causes of DVT. COVID-19 is associated with the classical syndrome named disseminated intravascular coagulation and the subsequent consumption coagulopathypresented as DVT.

Сomputed tomography (CT) is widely used in the diagnosis of  degenerative pathology of the lumbar spine, but the relationship  between clinical manifestations of lumbar stenosis and its anatomical prerequisites has not been sufficiently studied to date.The objective: to determine the significance of the morphometric  parameters of lumbar stenosis according to CT scans and to  establish their relationship with the prevailing symptoms of the disease.Material and methods. Seventy-five consecutive patients with  clinically significant lumbar stenosis who underwent CT scan before  surgery were enrolled in this study. The average values of thirteen  different morphometric parameters were calculated at LIII–SI levels of the intervertebral discs and of the pedicels in the axial and sagittal views. The possibility of classification of clinical observations and the correlation of morphometric parameters with the clinical forms of lumbar stenosis were investigated using discriminant and logistic regression analysis. Results. CT scan with high probability allocates patients with  predominant symptoms of neurogenic claudication or bilateral  radiculopathy. The most significant morphometric predictors of this  clinical group are the depth of the lateral recesses and the cross-sectional area of the spinal canal.Conclusion. CT scan significantly expands the informative value of  magnetic resonance imaging and can be used in planning the  decompressive stage of the surgery intervention in patients with lumbar spinal canal stenosis.

Introduction. It seems relevant to study the ultrasound anatomy and physiology of the proximal valve segments of the superficial femoral vein (SFV) and the great saphenous vein (GSV) to develop effective reconstructive surgical interventions on venous valves in chronic vein diseases.The aim of the survey was to study the ultrasound anatomy of the venous wall, the size and shape of the proximal SFV and GSV valves are normal at rest and during the functional test Valsalva.Material and methods. Proximal valve SFV studies were performed in 144 lower limbs in 115 people (mean age 51.1 ± 14.4 years, 60 women and 55 men), proximal GSV valves studies - in 82 lower limbs in 67 persons (average age 45, 1 ± 13.3 years, 33 women, 34 men). A longitudinal and transverse ultrasound scanning of the femoral vein bifurcation and safenofemoral junction areas were performed, the structures of the proximal SFV and GSV valves were visualized, the valve shape was measured and the diameter of the veins was measured at the level valves at the base of the valves (inlet diameter), at the point of maximum ectasia (diameter of ectasia), at the upper border of the valve (diameter of the outlet), as well as measuring the length of the valve a (length to ectasia, the total length of the valve). The degree of ectasia over the valve was judged by calculating the relative venous diameter change (RVDC).Results. the average diameter of the SFV at the level of the lower boundary of its first valve was 10.01 ± 1.44 mm. The average diameter of the SFV at the level of the maximum ectasia of its first valve was 13,1±2 mm. The average value of the index of RVDC for SFV was 31%±10,4%. An increase in the diameter of the vein in the zone of supravalvular ectasia up to 20% corresponded to the spindle-shaped valve, more than 20% - to the clavate form, which was noted in the majority of the examined. The change in the relative venous diameter of the SFV on the Valsalva test was 38,2%±12,4%. The average diameter of the GSV at the base of the first valves was 6,07±1,25 mm. The average diameter of the GSV at the level of the maximum ectasia of the osteal valve was 9,44±1,69 mm. The average RVDC for GSV was 58%±24%.Conclusion. the natural form of proximal SFV and GSV valves is clavate with presence of the significant supravalvular ectasia, which was noted in the majority of the subjects alone and in all during the performance of the Valsalva functional test.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease involving multiple organ systems. The kidney appears to be the most commonly affected organ, especially nephrotic is a serious kidney injury. The clinical, laboratory manifestations and histopathology are very useful for diagnosis, provide the means of predicting prognosis and guiding therapy in nephrotic patients with lupus nephritis. Methods: Descriptive cross-sectional study of nephrotic patients with lupus treated in the Department of Nephrology Trung Vuong Hospital and Cho Ray Hospital between May/2014 and May/2017. Renal histopathological lesions were classified according to International Society of Nephrology/Renal Pathology Society - ISN/RPS ’s 2003. The clinical, laboratory manifestations and histopathological features were described. Results: Of 32 LN with nephritic range proteinuria cases studied, 93.7% were women. The 3 most common clinical manifestations were edema (93.8%), hypertension (96.8%) and pallor (68.9%), musculoskeletal manifestions (46.9%), malar rash (40.6%). There was significant rise in laboratory and immunological manifestions with hematuria (78.1%), Hb < 12g/dL (93.5%), increased Cholesterol (100%), and Triglycerid (87.5%), Creatinine > 1.4 mg/dL (87.5%), increased BUN 71.9%, ANA (+) 93.8%, Anti Ds DNA(+) 96.9%, low C3: 96.9%, low C4: 84.4%. The most various and severe features were noted in class IV with active tubulointerstitial lesions and high activity index. Conclusion: Lupus nephritis with nephrotic range proteinuria has the more severity of histopathological feature and the more severity of the more systemic organ involvements and laboratory disorders were noted. Key words: Systemic lupus, erythematosus (SLE) lupus nepphritis, clinical

Introduction. Liver damage can be a dangerous side effect of using isoniazid. Individual susceptibility to isoniazid in humans is dependent on the presence of N-acetyltransferase 2 allelic variants in genome. It was imperative to assess the effect of genetically determined isoniazid acetylation rate in terms of risk of developing isoniazid-induced hepatotoxicity, as well as prevention of potential hepatopathy, and improvement of tuberculosis chemotherapy safety. Aim. To study the effect of acetylation type on the incidence of isoniazid hepatotoxicity in residents of the Sakha Republic (Yakutia) with newly diagnosed pulmonary tuberculosis. Methods. The study included 112 patients with newly diagnosed pulmonary tuberculosis. Genotyping was performed using real-time polymerase chain reaction. The following single nucleotide polymorphisms were studied: rs1801280, rs1799930, rs1799931, rs1799929, rs1208, rs1041983. Hepatotoxicity was determined based on the results of clinical laboratory monitoring and using the criteria developed by the European Association for the Study of the Liver (2019). Results. Hepatotoxic reactions developed more often in slow acetylators (43.2%), compared to fast acetylators (20.7%) and intermediate acetylators (10.9%); p=0.002. Serum alanine aminotransferase activity was 5 or more times above the upper limit of normal activity in 37.8% of slow acetylators, and in 8.7% of intermediate acetylators; p=0.001. Clinical manifestations of isoniazid hepatotoxicity were observed more often in slow acetylators (29.7%), than in fast acetylators (3.4%); p=0.000. Conclusion. Slow acetylation type ought to be considered an important risk factor for developing isoniazid hepatotoxicity in patients with pulmonary tuberculosis.

Abstract Background High-resolution computed tomography (HRCT) has proved to be an important diagnostic tool throughout the COVID-19 pandemic outbreaks. Increasing number of the infected personnel and shortage of real-time transcriptase polymerase chain reaction (RT-PCR) as well as its lower sensitivity made the CT a backbone in diagnosis, assessment of severity, and follow-up of the cases. Results Two hundred forty patients were evaluated retrospectively for clinical, laboratory, and radiological expression in COVID-19 infection. One hundred eighty-six non-severe cases with home isolation and outpatient treatment and 54 severe cases needed hospitalization and oxygen support. Significant difference between both groups was encountered regarding the age, male gender, > 38° fever, dyspnea, chest pain, hypertension, ≤ 93 oxygen saturation, intensive care unit (ICU) admission, elevated D-dimer, high serum ferritin and troponin levels, and high CT-severity score (CT-SS) of the severe group. CT-SS showed a negative correlation with O2 saturation and patients’ outcome (r − 0.73/p 0.001 and r − 0.56/p 0.001, respectively). Bilateral peripherally distributed ground glass opacities (GGOs) were the commonest imaging feature similar to the literature. Conclusion Older age, male gender, smoking, hypertension, low O2 saturation, increased CT score, high serum ferritin, and high D-dimer level are the most significant risk factors for severe COVID-19 pneumonia. Follow-up of the recovered severe cases is recommended to depict possible post COVID-19 lung fibrosis.

Abstract Background Collecting (Bellini) duct carcinoma (CDC) is a highly malignant and rare kidney tumor. We report our 12-year experience with CDC and the results of a retrospective analysis of patients and tumor characteristics, clinical manifestations, and imaging features by computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT. Methods Retrospective examination of tumors between January 2007 and December 2019 identified 13 cases of CDC from three medical centers in northern China. All 13 patients underwent CT scan, among which eight underwent dynamic enhanced CT scan, two underwent PET/CT scan, and one underwent magnetic resonance cholangiopancreatography (MRCP) examination. The lesions were divided into nephritis type and mass type according to the morphology of the tumors. Results The study group included ten men and three women with an average age of 64.23 ± 10.74 years. The clinical manifestations were gross hematuria, flank pain, and waist discomfort. The mean tumor size was 8.48 ± 2.48 cm. Of the 13 cases, six (46.2%) were cortical-medullary involved type and seven (53.8%) were cortex–medullary–pelvis involved type. Eleven (84.6%) cases were nephritis type and two (15.4%) were mass type. The lesions appeared solid or complex solid and cystic on CT and MRI. The parenchymal area of the tumors showed isodensity or slightly higher density on unenhanced CT scan in the 13 cases. PET/CT in two cases showed increased radioactivity intake. Evidence of intra-abdominal metastatic disease was present on CT in nine (69.2%) cases. Conclusions The imaging characteristics of CDC differ from those of other renal cell carcinomas. In renal tumors located in the junction zone of the renal cortex and medulla that show unclear borders, slight enhancement, and metastases in the early stage, a diagnosis of CDC needs to be considered. PET/CT provides crucial information for the diagnosis of CDC, as well as for designing treatment strategies including surgery.
