The Change of Erectile Function Post Recovery from COVID-19 Infection

INTRODUCTION

We assess the correlation between COVID-19 infection and erection and evaluate the effect of aging and comorbidities on the male sexuality of patients with COVID-19 infection.

METHODS

100 patients were enrolled and diagnosed with COVID-19 based on reverse transcription-polymerase chain reaction tests of oropharyngeal and nasopharyngeal swabs according to the WHO guidelines. The International Index of Erectile Function (IIEF-5) questionnaire was used to evaluate sexual function.

RESULTS

Patients were divided into two groups: the first group of 42 patients <50 years of age with a mean age (±SD) of 35.83 ± 7.8 and the second group of 58 patients ≥50 years of age with a mean age of 58.64 ± 7.7. The mean (±SD) IIEF in the first group pre-COVID-19 infection was 14.2 ± 2.37 while post-COVID-19 was 8.7 ± 2.77, 11.3 ± 2.9, 12.1 ± 3.02 at 1, 3, 6 months, respectively (p < 0.001), while in the second group, the mean (±SD) IIEF pre-COVID-19 infection was 10.04 ± 4.62 while post-COVID was 5.0 ± 2.1, 6.56 ± 2.6, 8.18 ± 2.04 at 1, 3, 6 months, respectively (p < 0.001). On multivariate analysis, old patients infected with COVID-19 and associated with comorbidities such as diabetes mellitus (OR = 8.53, CI = 0.00-2.01), hypertension (OR = 3.908, CI = 0.000-3.07), ischemic heart disease (OR = 2.863, CI = 0.000-2.68), and liver disease (OR = 0.670, CI = 0.000-1.670) were significantly correlated to erectile dysfunction (p < 0.001).

CONCLUSION

COVID-19 significantly affects erection mostly in older patients with comorbidities, leading to subsequent use of oral and intracavernosal injection therapy for erectile dysfunction.

Role Of Prostate Ultrasonography To Predict The Efficacy Of Bipolar Prostatectomy In Benign Prostatic Hyperplasia

Objectives

To evaluate the role of prostatic ultrasonography in predicting the clinical outcomes of bipolar transurethral resection of the prostate.

Method

The prospective study was conducted at the Urology Department, Kafrelsheikh University Hospital, Cairo, Egypt from December 2018 to June 2019, and comprised male patients complaining of lower urinary tractsymptoms due to benign prostatic hyperplasia. The patients were subjected to pelvi-abdominal and transrectal ultrasonography and values were noted for the international prostate symptom score, uroflowmetry, post-void residual urine volume, ejaculatory domain, and the erectile function domain of the international index of erectile function. The safety of the procedure was assessed using the modified Clavien classification of complications. This was followed by cystourethroscopy under spinal anaesthesia, and then by bipolar resection of the prostate by a single experienced urologist. Operating time, length of hospitalisation, intraoperative and postoperative complications, catheterization time, and changes in haemoglobin levels were recorded. All evaluations were done at baseline and postoperatively at 1, 3 and 6 months. Data was analysed using SPSS 21.

RESULTS

There were 109 male patients with mean age 65.53±6.27 years, mean body massindex 24.6±1.7kg/m2 . Mean total prostate volume at baseline was 86.32±43.61gm (range: 30-195m). There was a significant decrease postoperatively (p<0.001). This was associated with a concomitant improvement of international prostate symptoms score, uroflowmetry and post-void residual urine volume over six-month follow-up (p<0.001 ). Overall, 63(57.8%) subjects were sexually active, and there was no significant difference in the international index of erectile function score at baseline and postoperatively (p>0.05).

CONCLUSIONS

Prostate ultrasonography can be used as a single investigating tool to evaluate the clinical outcomes after bipolar transurethral resection of the prostate.

The scope of treatment of pediatric IgA vasculitis nephritis and its outcome: a Pediatric Nephrology Research Consortium study

BACKGROUND

IgA vasculitis (IgAV) is the most common type of vasculitis in children. There is a lack of consensus for management of significant IgAV nephritis (IgAVN). This study was designed to identify the most used treatment options and describe their efficacy.

METHODS

This is a multicenter retrospective study of children age 1-21 years with IgAVN who were managed for at least 6 months by a nephrologist. Subjects with at least microscopic hematuria and proteinuria and/or decreased kidney function were enrolled. Kidney outcome was assessed by eGFR and urine protein/creatinine (UPC) ratios at 2-4 weeks, 3, 6, and 12 months post-diagnosis.

RESULTS

A total of 128 subjects with median age of 7 years (range 2-18) were included. Of these, 69 subjects had kidney biopsy with crescents detected in 53%. AKI (P = 0.039), nephrosis (P = 0.038), and crescents on biopsy (P = 0.013) were more likely in older patients. Patients with UPC > 1 mg/mg were more likely to get a kidney biopsy (P < 0.001) and to be treated with steroids ± immunosuppressive (IS) agents (P = 0.001). Sixty-six percent of patients were treated with steroids and/or IS agents for variable durations. Anti-metabolite agents were the most common IS agents used with variability in dosing and duration. At 12 months, most subjects had a normal eGFR (79%) (median 123, range 68-207 mL/min/1.73 m²) and no proteinuria (median UPC 0.15, range 0.01-4.02 mg/mg).

CONCLUSIONS

IS agents are frequently used in managing IgAVN associated with heavy proteinuria, nephrosis, and/or AKI. Prospective studies are needed to determine indications and needed duration of IS therapy. A higher resolution version of the Graphical abstract is available as Supplementary information.

Emerging inflammatory bowel disease demographics, phenotype, and treatment in South Asia, South-East Asia, and Middle East: Preliminary findings from the Inflammatory Bowel Disease-Emerging Nations' Consortium

BACKGROUND AND AIM

Inflammatory bowel disease (IBD) is emerging in the newly industrialized countries of South Asia, South-East Asia, and the Middle East, yet epidemiological data are scarce.

METHODS

We performed a cross-sectional study of IBD demographics, disease phenotype, and treatment across 38 centers in 15 countries of South Asia, South-East Asia, and Middle East. Intergroup comparisons included gross national income (GNI) per capita.

RESULTS

Among 10 400 patients, ulcerative colitis (UC) was twice as common as Crohn's disease (CD), with a male predominance (UC 6678, CD 3495, IBD unclassified 227, and 58% male). Peak age of onset was in the third decade, with a low proportion of elderly-onset IBD (5% age > 60). Familial IBD was rare (5%). The extent of UC was predominantly distal (proctitis/left sided 67%), with most being treated with mesalamine (94%), steroids (54%), or immunomodulators (31%). Ileocolic CD (43%) was the commonest, with low rates of perianal disease (8%) and only 6% smokers. Diagnostic delay for CD was common (median 12 months; interquartile range 5-30). Treatment of CD included mesalamine, steroids, and immunomodulators (61%, 51%, and 56%, respectively), but a fifth received empirical antitubercular therapy. Treatment with biologics was uncommon (4% UC and 13% CD), which increased in countries with higher GNI per capita. Surgery rates were 0.1 (UC) and 2 (CD) per 100 patients per year.

CONCLUSIONS

The IBD-ENC cohort provides insight into IBD in South-East Asia and the Middle East, but is not yet population based. UC is twice as common as CD, familial disease is uncommon, and rates of surgery are low. Biologic use correlates with per capita GNI.

A Pattern of Glomerular Diseases in Egyptian Children: A Single-center Experience

BACKGROUND: Findings indicative of the glomerular disease are proteinuria, hematuria, nephrotic syndrome (NS), hypertension, and renal insufficiency. These presentations can be used to define different clinical patterns that resemble different underlying etiologies. METHODS: This study is a cross-sectional study enrolled in Children Hospital Cairo University. The study participants were recruited on two stages, retrospective and prospective stages. In the retrospective stage, all eligible patients across 5 years (between 2011 and 2015) with any glomerular disease were included in the study. In addition, prospectively, the new cases a long 6 months (from February 2016 till July 2016) with glomerular diseases were included in the study. RESULTS: A total of 594 cases with different glomerular diseases were identified. Cases were two groups: The retrospective group that involved 543 cases and the prospective group that included 51 cases. In the retrospective part of the study, the most common presentations were NS (68%), nephritis (16.4%), gross hematuria (10.5%), and nephrotic/nephritic syndrome (3.5%). The most common biopsies in the retrospective study were NS: MCNS (27.3%), NS: focal segmental glomerulosclerosis (FSGS) (23.4%), NS: Mesangioproliferative GN (9.4%), NS: Membranous GN (2.3%), Crescentric GN (3.9%), Membranous GN (0.8%), MPGN (0.8%), congenital nephrotic syndrome (CNS):Diffuse Mesangial Sclerosis (3.9%), CNS: Finnish type (2.3%), Alport (4.7%), IgA nephropathy (3.9%), IgM nephropathy (1.6%), lupus nephritis (LN) (3.1%), Thin basement membrane disease (3.1%), and others (9.4%) In the prospective study, the most common presentations were NS (76.5%), nephritis (11.8%), nephrotic/nephritic syndrome (7.8%), and gross hematuria (3.9%). The biopsies results were mainly NS: FSGS (33.3%) and NS: MCNS (33.3%). Other biopsies results in the prospective part were NS: Mesangioproliferative GN (16.7%), LN (8.3%), and IgA nephropathy (8.3%). CONCLUSION: The most common glomerular disease in childhood is NS. The most common pathology of glomerular diseases is minimal change NS.

Current status and needs for changes in critical care training: the voice of the young cardiologists

AIMS

The implementation of the 2013 European Society of Cardiology (ESC) Core Curriculum guidelines for acute cardiovascular care (acc) training among European countries is unknown. We aimed to evaluate the current status of acc training among cardiology trainees and young cardiologists (<40 years) from ESC countries.

METHODS AND RESULTS

The survey (March-July 2019) asked about details of cardiology training, self-confidence in acc technical and non-technical skills, access to training opportunities, and needs for further training in the field. Overall 614 young doctors, 31 (26-43) years old, 55% males were surveyed. Place and duration of acc training differed between countries and between centres in the same country. Although the majority of the respondents (91%) had completed their acc training, the average self-confidence to perform invasive procedures and to manage acc clinical scenarios was low-44% (27.3-70.4). The opportunities for simulation-based learning were scarce-18% (5.8-51.3), as it was previous leadership training (32%) and knowledge about key teamwork principles was poor (48%). The need for further acc training was high-81% (61.9-94.3). Male gender, higher level of training centres, professional qualifications of respondents, longer duration of acc/intensive care training, debriefings, and previous leadership training as well as knowledge about teamwork were related to higher self-confidence in all investigated aspects.

CONCLUSIONS

The current cardiology training program is burdened by deficits in acc technical/non-technical skills, substantial variability in programs across ESC countries, and a clear gender-related disparity in outcomes. The forthcoming ESC Core Curriculum for General Cardiology is expected to address these deficiencies.

Peripheral blood and hepatic Toll-like receptor 7 expression and interferon lambda 1 levels in chronic hepatitis C: Relation to virus replication and liver injury

BACKGROUND AND AIM

Toll-like receptor 7 (TLR7) can recognize single-stranded RNA viruses like hepatitis C virus (HCV) with subsequent induction of different interferon (IFN) types including IFN lambda (IFNL), which activate an immediate anti-viral response. However, the role of TLR7 in inflammation and fibrosis, characteristics of HCV-induced liver injury, is still controversial. The present work was designed to investigate the potential role of TLR7 and IFNL1 in chronic hepatitis C (CHC) in relation to viral replication and liver injury.

METHODS

Forty two treatment-naïve patients with CHC and 20 healthy subjects were enrolled in the study. TLR7 expression on peripheral blood CD14+ monocytes was studied by color flow cytometry and the frequency of TLR7+CD14+ cells was expressed as percentage of total monocyte count. Quantification of IFNL1 levels in serum was determined using enzyme-linked immunosorbant assay. Liver biopsies were examined for assessment of histological activity grade (A0-A3) and fibrosis stage (F0-F4) according to METAVIR scoring system as well as steatosis grade. Immunohistochemical staining was performed using human antibodies against TLR7 and IFNL1 and was scored semi-quantitatively (score 0-3). Hepatic expression of TLR7 and IFNL1 was further classified using a two-grade scale as low expression (score 0 or 1) and high expression (score 2 or 3).

RESULTS

Percentages of circulating TLR7+CD14+ monocytes and serum IFNL1 levels were significantly higher in patients with CHC than in healthy controls (P = 0.025 and P < 0.001 respectively) and were positively correlated with corresponding hepatic TLR7 and IFNL1 expression (P < 0.001 and P = 0.010 respectively). Significantly lower peripheral blood and hepatic TLR7 expression and IFNL1 levels were found in patients with viral loads between 200,000-600,000 IU/ml and >600,000 IU/ml than in those with viral load <200,000 IU/ml (P < 0.05), in patients with severe necroinflammation than in those with mild-to-moderate necroinflammation (P < 0.05) and in patients with advanced fibrosis than in those with early fibrosis (P < 0.01). Also, changes in TLR7 expression and IFNL1 production in peripheral blood and the liver were inversely correlated with serum levels of aspartate and alanine aminotransferases (P < 0.05) and HCV RNA (P < 0.01), histological activity grade (P < 0.01) and fibrosis stage (P < 0.01). By plotting receiver operating characteristics (ROC) curve, serum IFNL1 showed higher sensitivity and specificity than percentages of circulating TLR7+CD14+ monocytes in discriminating patients with CHC according to the severity of hepatic necroinflammation (area under the curve (AUC) = 0.901 vs. 0.816 respectively) and fibrosis (AUC = 0.971 vs. 0.825 respectively) at a cut-off value of 44.75 pg/ml and 10.25% respectively.

CONCLUSIONS

TLR7 activation and IFNL1 production in CHC may play an important role in controlling viral replication and limiting hepatic inflammation and fibrosis and their downregulation may result in viral persistence and disease progression. The immunoregulatory role of TLR7-IFNL1 pathway in the pathogenesis of chronic HCV infection should be further studied. Clinical trials with a large number of patients are needed to assess the usefulness of serum IFNL1 as a potential biomarker for severity of liver injury in chronic HCV infection and other liver diseases.

Decreased apoptosis in advanced-stage/high-grade hepatocellular carcinoma complicating chronic hepatitis C is mediated through the downregulation of p21 ras

OBJECTIVE AND BACKGROUND

Although p21 ras has been reported to be upregulated in hepatocellular carcinoma complicating chronic hepatitis C type I, p21 ras has a different role in advanced stages, as it has been found to be downregulated. The goal of this study was to investigate the status of p21 ras in early-stage/low-grade and late-stage/high-grade hepatocellular carcinoma and its possible link to apoptosis.

MATERIAL AND METHODS

Thirty-five cases each of chronic HCV hepatitis type 4 (group I) and cirrhosis with hepatocellular carcinoma (HCC) complicating chronic HCV hepatitis (groups II and III) were immunohistochemically evaluated using a p21 ras polyclonal antibody. The apoptotic index was determined in histologic sections using the terminal deoxynucleotidyl transferase-mediated d-UTP biotin nick end labeling (TUNEL) assay.

RESULTS

Significant differences (P=0.001) were detected in p21 ras protein expression between the three groups. A near 2-fold increase in p21 ras staining was observed in the cirrhotic cases compared to the hepatitis cases, and p21 ras expression was decreased in the HCC group. p21 ras expression correlated with stage (r=0.64, P=0.001) and grade (r=(-)0.65, P=0.001) in the HCC group and grade in the HCV group (r=0.44, P=0.008). Both p21 ras expression and TUNEL-LI were significantly lower in large HCCs compared to small HCCs (P=0.01 each). The TUNEL values were negatively correlated with stage in the HCC group (r=(-)0.85, P=0.001). The TUNEL values were also negatively correlated with grade in both the HCV and HCC groups (r=0.89, P=0.001 and r=(-)0.53, P=0.001, respectively). The p21 ras scores were significantly correlated with the TUNEL-LI values in the HCC group (r=0.63, P=0.001) and HCV group (r=0.88, P=0.001).

CONCLUSIONS

p21 ras acts as an initiator in HCC complicating type 4 chronic HCV and is downregulated with HCC progression, which most likely promotes tumor cell survival because it facilitates the downregulation of apoptosis with tumor progression.

A new type of Ehlers-Danlos syndrome associated with tortuous systemic arteries in a large kindred from Qatar

AIM

To describe the clinical spectrum of anomalies of a new type of Ehlers-Danlos syndrome in 32 patients from a large inter-related extended family in Qatar.

METHODS

Among the 32 patients (from 22 families), there were 6 affected pairs of siblings and 2 families with 3 affected siblings. The male to female ratio was 2:1, ages ranging from birth to 18 y (mean 7.4 y).

RESULTS

Anomalies included a variable degree of skin hyperextensibility, hypermobility of small and large joints, and tortuous systemic arteries. Peculiar facial features included epicanthic folds, flat saggy cheeks, elongated faces and micrognathia. The combination of an elongated aortic arch and tortuous brachiocephalic arteries was seen in 30 patients (93.8%), aneurysm of the ascending aorta in 3 patients (9.4%), bifid pulmonary artery in 27 patients (84.4%) and multiple severe peripheral stenosis of the right and/or left pulmonary artery in 7 patients (21.9%). A prominent aortic knuckle was observed on the chest roentgenograms of 30 patients (93.8%); inguinal hernia in 11 patients (34%), diaphragmatic hernia and/or hiatus hernia in 7 patients (21.9%); and laryngo-tracheomalacia in 2 patients (6.3%). Generalized muscle hypotonia was found in 15 neonates (46.9%). Parental consanguinity involved in all the patients was traced to a common ancestor from a large Bedouin tribe in Qatar. These patients are at risk for potentially catastrophic arterial rupture. Linkage to the major loci involved in Ehlers-Danlos syndrome and other connective tissue disorders, such as Cutis Laxa, Familial Aneurysm, and Osteogenesis imperfecta, was excluded by using specific DNA markers, confirming the uniqueness of this disorder.

CONCLUSION

The study describes a large cohort of patients from the same closely related family, sharing peculiar dysmorphisim and consistent radiological and echocardiographic features different from known types of Ehlers-Danlos syndrome. As known loci involved in Ehlers-Danlos syndrome and other connective tissue disorders were excluded by specific DNA markers, this appears to be a new type of Ehlers-Danlos syndrome or even a new syndrome.

Solitary bronchial papilloma presenting with recurrent dyspnea attacks: case report with computed tomography findings

A case of solitary bronchial papilloma is reported which, because of its unusual location near the carina and marked mobility, presented with attacks of dyspnea that were misdiagnosed as asthma for many years. It caused no abnormality on a plain chest X-ray, but could be visualized on linear and computed tomograms. The computed tomograms further demonstrated the absence of extraluminal extension of the tumor or mediastinal lymphadenopathy which could not be excluded by linear tomography or bronchoscopy. Transbronchial resection resulted in complete relief of symptoms.
