    Abstract Purpose: Non-alcoholic fatty liver disease (NAFLD) shares a close relationship with cardiovascular morbidity and mortality. The purpose of this study is to evaluate the frequency of NAFLD in the patients with non-diabetic chronic kidney disease (CKD).
    Methods: This cross-sectional study included 80 patients with non-diabetic CKD, of which, 50 patients were on hemodialysis (HD) and 30 patients had CKD stage G3-5 not on dialysis. These patients were randomly selected from Ain Shams University Hospitals, Cairo, Egypt. Patients with diabetes mellitus, obesity, alcohol intake, viral hepatitis, or drug-induced liver steatosis were excluded from this study. Importantly, the controlled attenuation parameter (CAP) (dB/m) of liver steatosis (S0-S3) and liver stiffness/fibrosis measurement (F0-F4) were measured using transient elastography (Fibroscan
    Results: In total, 45 (56.25%) (30 males, 15 females) out of total 80 studied patients were reported to have NAFLD. There were 29 patients with end-stage renal disease who were on regular HD and 16 patients with pre-dialysis CKD G3-5. The mean CAP values of hepatic steatosis in the patients with CKD on dialysis and patients with pre-dialysis CKD were 265.41 ± 52.73 and 259 ± 44.8 dB/m, respectively. A significant association between the severity of hepatic steatosis degree with decreased glomerular filtration rate and increased CKD stage was observed in this study. The degree of liver stiffness was significantly related to an increased hepatic steatosis grade. A significant positive correlation was found between the degree of NAFLD and serum levels of alanine aminotransferase, aspartate transaminase, total cholesterol, triglycerides, low-density lipoprotein, and CRP titer (P < 0.05). Importantly, NAFLD was significantly associated with an evident history of cardiovascular disease (CVD) among the studied patients.
    Conclusion: A high frequency of NAFLD (56%) was observed among the patients with non-diabetic CKD on hemodialysis and patients with pre-dialysis CKD. NAFLD may be associated with an increased liver stiffness grade and CVD among those patients.

    Abstract Background: Reactivation of herpesviruses such as Epstein-Barr virus (EBV) and cytomegalovirus (CMV) in COVID-19 patients reported in many studies in different countries during the pandemic. We aimed to measure prevalence of this coinfection in Egyptian COVID-19 patients with elevated liver enzymes and its relation to the severity and the outcome of COVID-19 infection in those patients.
    Methods: A cross-sectional study was carried out on 110 COVID-19 patients with elevated liver enzymes regardless the severity of COVID-19 disease. All patients were subjected to medical history, clinical examination, laboratory investigations, high-resolution computed tomography chest (HRCT chest). Epstein-Barr virus (EBV) and Human cytomegalovirus (HCMV) were determined by VCA IgM and CMV IgM respectively by enzyme-linked immunosorbent assay (ELISA).
    Results: Of the included 110 patients with COVID-19 illness, 5 (4.5%) were Epstein-Barr virus seropositive and 5 (4.5%) were human cytomegalovirus seropositive. Regarding the symptoms, the incidence of fever in the EBV and CMV seropositive group was apparently higher than that in the EBV and CMV seronegative group. In lab tests, the platelets and albumin of EBV and CMV seropositive group decreased more significantly than EBV and HCMV seronegative group, and serum ferritin, D-dimer, and C-reactive protein show higher values in seropositive group than in seronegative group but not statistically significant. Seropositive group had received higher doses of steroids than seronegative group. The median of hospital stay in seropositive group was (15 days) nearly double that of seronegative group with statistically significant difference between both groups.
    Conclusion: Coinfection of EBV and CMV in COVID-19 Egyptian has no effect on the disease severity or the clinical outcome of the disease. But those patients had higher hospital stay duration.

    Abstract Our patient, who had been previously diagnosed with non-small cell lung cancer, presented with progressive dyspnoea after receiving second-line immunotherapy treatment with atezolizumab. Chest CT scan showed bilateral lung architectural distortion, bronchial dilatation, consolidative opacities, ground-glass opacities and linear opacities concerning for either infectious lung disease or treatment-related lung disease. A diagnostic bronchoscopy was performed and no evidence of malignancy or infection was detected. Discontinuing atezolizumab with the addition of oral corticosteroid improved the patient's respiratory symptoms but the patient required continuous oxygen supplementation. Later, the patient was found to have radiologic findings suggestive of further progression of his pneumonitis after completion of a course of corticosteroid treatment and required another course of oral prednisone. Immune-mediated pneumonitis could present with mild to severe respiratory symptoms with a wide range of clinical and radiologic features and physicians should be aware of this diagnosis of exclusion. Although patients may experience progressive disease with or without immunotherapy rechallenge, most of these cases can be managed successfully with favourable outcomes.

    Abstract We report a case of a 60-year-old man who was a former cigar smoker with a slow-growing, large exophytic left shoulder mass (15 cm in diameter) and later found to have left axillary lymphadenopathy. Fine needle aspirate biopsy of the left shoulder mass revealed squamous cell carcinoma (SCC). However, pathology of the enlarged left axillary lymph node was reported as metastatic adenocarcinoma. The patient underwent surgical resection of the shoulder mass which comprised of SCC (>95%) and adenoid basal cell carcinoma (BCC) as a second component of the tumour. The BCC had identical histology as the metastatic carcinoma in the left axillary lymph node. Therefore, diagnosis was revised as cutaneous collision tumour with metastatic BCC. Six months later following adjuvant radiation therapy, the patient was diagnosed with metastatic BCC in the right lung. Stereotactic body radiation therapy (SBRT) and a selective hedgehog pathway inhibitor vismodegib were given with only limited efficacy. Clinical trial registration number NCT03132636.

    Abstract Background and aim: After a decrease of COVID-19 cases in summer, Europe faced the appearance of a COVID-19 second wave. IBD patients are more vulnerable to various emotional and psychological stresses than normal individuals. The aim of this study explored the emotional state, perception, and coping strategies of patients with IBD during the COVID 19 pandemic period.
    Methods: A cross-sectional study was conducted between 15 November and 15 December 2020. Patients presented to IBD Study Group Clinic, Department of Tropical Medicine, Ain Shams University Hospitals. The study included 105 IBD patients. A predesigned questionnaire was used that focused on patients' knowledge of the COVID-19 pandemic, and how it influenced patient care. Patient demographics, disease characteristics, and medication type were analyzed.
    Results: We found 10.5% of patients stopped or delayed their medications owing to the COVID-19 pandemic second wave and 61% reported that their clinic visits were affected. Seven patients were tested, and two patients reported having been diagnosed with COVID-19, and 18 patients reported having relatives diagnosed with COVID-19.
    Conclusion: A considerable number of patients with IBD had an interruption to their care because of the second wave COVID-19 pandemic. So, patients with IBD should take attention before, during, and after such pandemics to avoid undesirable disease-related outcomes.

    Abstract Background: The aim of study to identify the characterizations of Crohn's disease in Egyptian patients and to determine its predictors for postoperative recurrence.
    Methods: We conducted a retrospective observational cohort study on 15 patients diagnosed as Crohn's disease with surgical interventions. Different characteristics of studied patients were analyzed to determine the risk factors for postoperative recurrence such as age at diagnosis, gender, smoking, main presenting symptom, Montreal classification, perianal disease, laboratory findings and protocol of management including surgical characteristics like age at operation, surgical indication, preoperative medication, surgical approach, and operative findings.
    Results: Nine of the studied patients (60%) suffered from clinical postoperative recurrence with mean duration of 23.5 ± 40.6 months. In comparison the demographic, clinical, operative, and medical treatment data between patients with postoperative recurrence of Crohn's disease and those without recurrence, age at diagnosis (mean age 42.9 years) and age at operation (mean 44.7 years) were found statistically significant in postoperative recurrence group (p-value = 0.001). According to Montreal classification of Crohn's disease, patients >40 years were significantly found in postoperative recurrence group, while patients between 17 and 40 years were significantly found in postoperative non-recurrence group (p-value=0.007) and ileal location of Crohn's disease was found significantly in postoperative recurrent group (p-value=0.044). Postoperative biological therapy significantly decreased the incidence of postoperative recurrence in the current study (p-value= 0.041).
    Conclusions: Age at diagnosis, age at operation, ileal location of Crohn's disease can significantly predict postoperative recurrence. Also, postoperative biological therapy can significantly decrease the incidence of postoperative recurrence.

    Abstract This article reviews regional lymph node assessment in lung cancer. In the absence of a distant metastasis, the absence or location of lung cancer spread to a regional mediastinal lymph node affects treatment options and prognosis. Regional lymph node maps have been created to standardize assessment of the N descriptor. The International Association for the Study of Lung Cancer lymph node map is used for the standardization of N descriptor assessment. CT, PET/CT with fluorodeoxyglucose, endobronchial ultrasound-guided and/or esophageal ultrasound-guided biopsy, and mediastinoscopy are common modalities used to determine the N descriptor.
