Background: Basal cell carcinoma (BCC) is the most common cancer in the Caucasian population. It has a multifactorial pathogenesis, in which constitutive activation of the Sonic Hedgehog signalling (SHH) pathway (via mutations in PTCH1 or SMO genes) represents by far the most common genetic aberration. The introduction of vismodegib and sonidegib, two SHH pathway inhibitors, changed the therapeutic approach of locally advanced and metastatic BCCs. EADO's (European Association of Dermato-Oncology) new staging system refers to these as 'difficult-to- treat' BCCs. Objective: The aim was to evaluate sonidegib's effectiveness in patients affected by difficult-to-treat BCCs by using non-invasive diagnostic techniques. Methods: We retrospectively evaluated 14 patients (4 females, 10 males; mean age 77 ± 11 years) affected by difficult-to-treat BCCs treated with oral sonidegib 200 mg/ day that were followed with total body videodermoscopy (V-Track, Vidix 4.0) and dynamic optical coherence tomography (D-OCT, VivoSight Dx) since May 2022. Considering the risk of rhabdomyolysis routine blood tests, especially for creatine kinase concentrations, were performed. All treated patients were inserted in the BasoCare database, which aims to offer support to patients taking sonidegib. Complete and partial responses were evaluated by the overall reduction of the number of lesions and their individual sizes. Safety was evaluated by assessing the occurrence and severity of adverse reactions. Results: Eighty per cent achieved complete clearance and 75% reduction of diameter. D-OCT scans performed at every follow-up showed concordance with clinical appearance and demonstrated reduction of hyporeflective structures, that is, islets of tumour cells and overall improvement of morphology. Conclusion: Sonidegib can be considered an effective treatment option in cases where surgery or radiotherapy would be unfeasible or has previously failed, although pigmented lesions did not show complete clearance, suggesting that there are factors other than the SHH pathway involved in tumour growth. Videodermoscopy and DOCT were useful in the quick and seamless follow-up of lesions and added valuable information in assessing efficacy. [ABSTRACT FROM AUTHOR]

OBJECTIVE: COVID-19 is an extremely contagious illness caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV-2), that will keep broadly circulating and evolving. Collected evidence revealed the clinical profile of COVID-19 patients as a potential predictor of their outcome. The aim of this study was to investigate the causal relationship between poor outcomes and laboratory parameters in hospitalized COVID-19 patients, in this sense observing how SARS-CoV-2 infection affects other organs. PATIENTS AND METHODS: We retrospectively evaluated a cohort of 133 patients, positive for SARS-CoV-2, aged between 30 to 94 years, between January 12th and April 25th, 2021. Discharge from the hospital, transferral to the ordinary ward or nursing home, intensive care unit (ICU) admission, and in-hospital mortality were recorded, along with demographic, laboratory and clinical parameters. The whole sample was summarized by median (interquartile range) for quantitative data, and absolute and relative percentage frequencies for qualitative variables. Univariable logistic regression models were performed to assess the association between all the parameters of interest and COVID-19 adverse outcomes, single (in-hospital mortality) and composite (in-hospital mortality and ICU admission). Hence, a multivariable model was fitted to identify potential independent predictors of the composite outcome. The accuracy of the model was assessed through appropriate fitting indices, such as the C-statistic and Hosmer-Lemeshow test. Moreover, to detect multicollinearity, the variance inflation factor (VIF) was used. RESULTS: Our study sample had a median age of 72 years old (59.0-83.0). The most common comorbidities were hypertension (63.7%), cardiovascular disease (41.9%), diabetes (33.6%), and cerebrovascular disease (21.5%); while as the most common symptoms, we observed dry cough (32.5%), dyspnoea (50.8%), and fatigue (29.8%). Totally, 18 patients died during hospitalization (13.5%), 10 required ICU admission (7.5%), 78 (58.6%) were discharged from the hospital, and 27 (20.3%) were transferred to either ordinary wards or nursing homes. We disclosed an association of older age with both composite [OR 1.06, 95% CI 1.02-1.09; p=0.003] and single outcome [OR 1.10, 95% CI 1.04-1.16; p=0.001]. A higher oxygen saturation (SpO2) was associated with a better outcome [OR 0.75, 95% CI 0.60-0.93; p=0.009 and OR 0.76, 95% CI 0.61-0.95, p=0.009]. Among laboratory parameters, higher levels of neutrophils increased the risk of a poor outcome [OR 1.05, 95% CI 1.00-1.10; p=0.043]; while higher levels of lymphocytes seem associated with a better outcome [OR 0.94, 95% CI 0.88-0.99; p=0.043]. Higher levels of creatinine were associated with a higher risk of both adverse outcomes [OR 6.20, 95% CI 2.16-17.81; p<0.001 and OR 19.90, 95% CI 5.07-78.06; p<0.001, respectively]. Higher levels of sodium (Na) were associated with a higher risk of adverse events [OR 1.15, 95% CI 1.03-1.28; p=0.014 and OR 1.14, 95% CI 1.01-1.27]. Similar findings were also observed for C-reactive protein (CRP) levels [OR 1.01, 95% CI 1.00-1.02; p=0.010 and OR 1.01, 95% CI 1.00-1.02; p=0.024]. Conversely, being positive to IgM and IgG decreases the risk of adverse outcomes [IgM: OR 0.33, 95% CI 0.14-0.77; p=0.011 and OR 0.23, 95% CI 0.08-0.66; p=0.006. IgG: OR 0.30 95% CI 0.13-0.72; p=0.007 and OR 0.22 95% CI 0.07-0.66; p=0.007]. Hence, a multivariable model was fitted to identify potential independent laboratory predictors of the composite outcome, with laboratory parameters that showed an association with composite outcome. The model can be considered accurate according to Hosmer-Lemeshow test and C-statistic [p>0.83, C-stat=0.90]. CONCLUSIONS: Our findings confirm that COVID-19 is a multiorgan disease. In fact, the analysis of laboratory parameters has revealed a strong relationship between poorer outcomes and multiple organ dysfunction, particularly established by higher levels of neutrophils, creatinine, sodium, and CRP. Alongside, cerebrovascular diseases, chronic kidney disease and older age supported this finding. Of note, higher levels of SpO2, and lymphocytes, as well as positivity to IgM and IgG were associated with a lower risk of a poor outcome. [ABSTRACT FROM AUTHOR]

The article focuses on the management of onset of hepatocellular carcinoma in hepatitis C virus patients who achieved the sustained virological response after treatment with direct acting antivirals. It mentions that despite the fact that the direct acting antivirals therapies are able to remove the hepatitis C virus from the patients, the epigenetic impact on cells persist also in absence of the virus itself.

In the last decades a growing interest has been dedicated to prevention, diagnosis and therapy of male genital pathologies, such as varicocele, infertility and erectile dysfunction in the population involved in sport activities. High incidence (up to 30%) of varicocele has been reported in a population of athletes and up to 60-80% in the subgroup of body-builders. The incidence of varicocele specifically increases with hours of training, in a linear model. Controversial data come from literature about the effects of physical activity on fertility, with prevalence of trials demonstrating worsening of seminal parameters. Furthermore, it has been demonstrated that physical stress in healthy male athletes can interfere with LH levels. Bicycling is one of the major risk factors for erectile dysfunction, with incidence of 13-24%. This is due to the prolonged compression of perineal arteries leading to reduced chronic penile perfusion. Bioengineering studies have been the basis for industry to produce specifically shaped saddles that significantly reduce and minimize compressive effects. Finally, high frequency of lower urinary tract symptoms (LUTS) in cyclists has been related to increased incidence of erectile dysfunction in comparison with normal population.

Peyronie’s disease (PD) is characterized by the onset of fibrous plaque inside the tunica albuginea of the penile corpora cavernosa that can cause pain and bending during the erection, making intercourse difficult or impossible. Evidence of the literature supports the autoimmune etiology of PD and suggests genetic and familiar conditions, penile traumatisms, and a history of genital tract diseases as risk factors, but no definitive conclusions arise about the pathogenesis of the disease. Few randomized trials demonstrated that medical therapies, such as vitamin E, colchicine, potassium aminobenzoate, tamoxifen, and injection therapy with verapamil, can stabilize the acute phase of the disease. Extracorporeal shock wave therapy and iontophoresis cannot be considered first-line or gold standard therapies. Satisfactory results have been published with the Nesbit operation in large series with low-stage disease, whereas plication procedures have shown significant relapse rates. A high incidence of long-term penile retractions has been reported in high-stage disease treated with plaque incision and simple graft insertion. Malleable, soft, or inflatable prostheses combined with graft implantation have given the best results in terms of penile straightening and lengthening and patient satisfaction. In conclusion, the etiopathogenesis of PD is not yet clearly understood, no medical therapy is fully effective, and surgery remains the gold standard in patients with severe deformity and/or erectile dysfunction.

Treatment satisfaction, subanalysed by demographic variables, was evaluated in patients switching from successful intracavernosal prostaglandin E1 (PGE1) therapy to oral sildenafil citrate. The validated Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire was administered at the end of PGE1 therapy and after 12 weeks of sildenafil treatment in a multicentre, open-label study. Men with erectile dysfunction (n=176) who were switched from stable PGE1 therapy to sildenafil (25-100?mg) were equally satisfied with onset of action, duration of action, and confidence in ability to engage in sexual activity, but expressed greater overall treatment satisfaction with sildenafil (P<0.01), better ease of use (P<0.001), naturalness of erectile process (P<0.001), and intention to continue treatment (P<0.001). Partners (n=32) were overall more satisfied with sildenafil (P<0.05), and their responses correlated with patient satisfaction (r=0.68). Compared with PGE1 injection, these data suggest that patients may be less likely to discontinue taking sildenafil treatment for their erectile dysfunction.International Journal of Impotence Research (2003) 15, 444-449. doi:10.1038/sj.ijir.3901049 [ABSTRACT FROM AUTHOR]

Our purpose was to evaluate a pharmacological and dietary protocol of prophylaxis and treatment of acute actinic esophagitis during mediastinal radiotherapy. This phase II study was conducted on 29 patients affected by cancer not directly involving the esophagus. The irradiated volume included at least 10 cm of esophagus with a median dose of 46 Gy and the incidence of clinical acute esophagitis was scored with RTOG-EORTC tables. During the entire course of radiation therapy all patients were subjected to prophylaxis pharmacological therapy in addition to dietetic rules commonly used. All patients were evaluable, 9 (31%) had no acute esophageal toxicity, 20 (69%) had toxicity of degree 1, and no patient showed a toxicity of degree 2, 3, or 4, there were no toxicity-related related interruptions of the radiotherapy course. In conclusion, this low cost protocol seems to reduce the incidence and degree of acute radiation esophagitis (without added morbidity), compared with literature reports. [ABSTRACT FROM AUTHOR]

Background: Although hepatic steatosis is seen with increasing frequency in clinical practice, its prevalence and risk factors are unknown.Objective: To investigate the prevalence of and risk factors for hepatic steatosis, such as alcohol consumption and obesity.Design: Cross-sectional, observational study.Setting: Participants in the Dionysos Study.Patients: 257 participants assigned to one of four categories (67 controls, 66 obese persons, 69 heavy drinkers, and 55 obese heavy drinkers).Measurements: Ethanol intake, assessed by a validated questionnaire and expressed as daily (g/d) and lifetime (kg) consumption, and body mass, expressed as body mass index. Biochemical tests of liver and metabolic function and hepatic ultrasonography were done.Results: The prevalence of steatosis was increased in heavy drinkers (46.4% [95% CI, 34% to 59%]) and obese persons (75.8% [CI, 63% to 85%]) compared with controls (16.4% [CI, 8% to 25%]). Steatosis was found in 94.5% (CI, 85% to 99%) of obese heavy drinkers. Compared with controls, the risk for steatosis was higher by 2.8-fold (CI, 1.4-fold to 7.1-fold) in heavy drinkers, 4.6-fold (CI, 2.5-fold to 11.0-fold) in obese persons, and 5.8-fold (CI, 3.2-fold to 12.3-fold) in persons who were obese and drank heavily. In heavy drinkers, obesity increased the risk for steatosis by twofold (CI, 1.5-fold to 3.0-fold) (P < 0.001), but heavy drinking was associated with only a 1.3-fold (CI, 1.02-fold to 1.6-fold) increase in risk in obese persons (P = 0.0053). Elevated alanine aminotransferase and triglyceride levels are the most reliable markers of steatosis.Conclusions: Steatosis is frequently encountered in healthy persons and is almost always present in obese persons who drink more than 60 g of alcohol per day. Steatosis is more strongly associated with obesity than with heavy drinking, suggesting a greater role of overweight than alcohol consumption in accumulation of fat in the liver.

A case of metachronous renal cell carcinoma is reported in a 52-year-old male patient who had previously undergone radical nephrectomy for cancer in 1989. He was thereafter monitored with annual CT-scans. In January 1994, a small, solid, renal parenchymal mass was detected in the opposite kidney. Following that, three consecutive abdominal CT-scans were carried out over the year in order to evaluate any changes. Subsequently, elective right nephron-sparing resection was performed. This report discusses neoplasm detection, evolution and clinical approach in a patient with previous nephrectomy for cancer. [ABSTRACT FROM AUTHOR]

Varicocele is the most common diagnosis in men presenting to fertility clinics. Traditional indications for correction of Varicocele include scrotal pain, testicular atrophy, and infertility without other apparent causes. Adolescent Varicocele correction is indicated if pain or testicular growth retardation is present. Following varicocelectomy most studies report improved semen parameters, increased semen testosterone, improvement in functional sperm defects, and the return of motile sperm in selected azoospermic men. However, conflicting data supporting the effectiveness of repairing subclinical varicoceles is sparse. Most authors generally agree that the primary effect of varicoceles is on testicular temperature. Varicoceles are diagnosed primarily by physical examination. Radiographic assessment are helpful when physical examination is inconclusive or when further objective documentation of a patient''s condition is necessary. Several surgical approaches to varicocelectomy exist, each with its own advantages and drawbacks, but the sub-inguinal approach to varicocelectomy is preferred by the clinic, also when there is a history of previous inguinal surgery. Routine use of an operating loops and a micro Doppler probe affords easier identification of vessels and lymphatics. Local anaesthesia is performed. Varicocele remains the most surgically treatable form of male infertility. Knowing the correct techniques of diagnosis and surgical correction ensures the best chance of successful outcomes in terms of post-operative morbidity, improved semen parameters, and pregnancy rates.
