Abstract. To investigate the role of gonadotropins in postnatal testicular activation, testosterone responsiveness to human chorionic gonadotropin was studied in 11 male infants (aged 5-180 days). The boys were given a single im injection of 5000 IU/1.7m2 hCG, and serum and salivary testosterone responses were then measured for 7 days. The results were compared with the serum testosterone responses of 8 older prepubertal boys (aged 1.7-10.4 years) studied with the same protocol. The mean (±sem) basal serum testosterone levels were 2.67±1.27 nmol/l in the infants and 0.09±0.02 nmol/l in the prepubertal boys (p<0.05). Both groups gave a significant response to hCG stimulation (p<0.001, ANOVA, one-way). The stimulated concentrations of serum testosterone were higher in the infants than in the prepubertal boys (p<0.001). The mean basal level of salivary testosterone was 30.5 ±7.0 and the mean maximal level was 97± 10.3 pmol/l in the infants (p<0.001). No age-related changes were observed in either basal or hCG-stimulated levels. In infants the mean (±sem) maximal hCG-stimulated increase was 25 ± 10-fold in serum and 8±4-fold in saliva (p=0.13). A clear stimulatory effect of hCG on testicular testosterone production was found, suggesting that the postnatal increase in serum testosterone concentration in male infants is gonadotropin-mediated. Salivary testosterone concentrations can be increased by hCG, indicating that measurements of salivary testosterone may provide an optional, non-invasive method for assessing gonadal function in children.

Abstract Objectives The purpose of this study was the assessment of volumetric CT perfusion (CTP) of the lower leg musculature in patients with symptomatic peripheral arterial disease (PAD) before and after interventional revascularisation. Methods Twenty-nine consecutive patients with symptomatic PAD of the lower extremities requiring interventional revascularisation were assessed prospectively. All patients underwent a CTP scan of the lower leg, and hemodynamic and angiographic assessment, before and after intervention. Ankle-brachial pressure index (ABI) was determined. CTP parameters were calculated with a perfusion software, acting on a no outflow assumption. A sequential two-compartment model was used. Differences in CTP parameters were assessed with non-parametric tests. Results The cohort consisted of 24 subjects with an occlusion, and five with a high-grade stenosis. The mean blood flow before/after (BFpre and BFpost, respectively) was 7.42 ± 2.66 and 10.95 ± 6.64 ml/100 ml*min−1. The mean blood volume before/after (BVpre and BVpost, respectively) was 0.71 ± 0.35 and 1.25 ± 1.07 ml/100 ml. BFpost and BVpost were significantly higher than BFpre and BVpre in the treated limb (p = 0.003 and 0.02, respectively), but not in the untreated limb (p = 0.641 and 0.719, respectively). Conclusions CTP seems feasible for assessing hemodynamic differences in calf muscles before and after revascularisation in patients with symptomatic PAD. We could show that CTP parameters BF and BV are significantly increased after revascularisation of the symptomatic limb. In the future, this quantitative method might serve as a non-invasive method for surveillance and therapy control of patients with peripheral arterial disease. Key Points • CTP imaging of the lower limb in patients with symptomatic PAD seems feasible for assessing hemodynamic differences before and after revascularisation in PAD patients. • This quantitative method might serve as a non-invasive method, for surveillance and therapy control of patients with PAD.

Colonic Diverticula

Giant colonic diverticula are a rare manifestation of diverticular disease and there are fewer than 150 cases described in the literature. They may have an acute or chronic presentation or may remain asymptomatic and be found incidentally. As the majority (over 80%) of giant diverticula are located in the sigmoid colon, they usually present with left-sided symptoms but due to the variable location of the sigmoid loop, right-sided symptoms are possible. We describe the acute presentation of an inflamed giant sigmoid diverticulum with right iliac fossa pain. We discuss both the treatment options for this interesting condition and also the important role of computed tomography in the diagnosis and management of abdominal pain in elderly patients.

Mummy 527 B* belongs to the “Giovanni Marro” Egyptian Collection of the Museum of Anthropology and Ethnography of the University of Turin. This mummy of a oneyear- old pre-dynastic child was found in Gebelein in 1935 in a small necropolis discovered during excavations of the “Missione Archeologica Italiana” led by G. Farina, the new Director of the Egyptian Museum of Turin, with the participation of Prof. G. Marro as anthropologist. A whole body spiral CT scan with thin slices (1,00 mm thickness, 0,5 mm reconstruction interval) was followed by multiplanar and 3D reconstruction. The aim was to evaluate the child’s age at death and the presence of lethal pathologies. This study confirms the fundamental role of non-invasive techniques in the study of such rare pre-dynastic specimens.

Abstract Background Hepatocellular carcinoma (HCC) is the sixth most common malignancy worldwide and it is also a common cause of death in patients with chronic liver disease. The curative treatment options for HCC that are currently available are surgical resection, liver transplantation and radiofrequency ablation .Despite progressive improvements in the efficacy of RFA, the survival of patients with HCC who undergo RFA remains disappointing, mainly due to frequent intrahepatic recurrence of HCC after RFA. Aim of the work To evaluate the role of transient elastography (as an indirect indicator to degree of liver fibrosis) in prediction of denovo recurrence of hepatocellular carcinoma after radiofrequency ablation in hepatitis C related hepatocellular carcinoma .And to compare between transient elastography and other non invasive fibrosis indices in prediction of denovo recurrence of hepatocellular carcinoma after radiofrequency ablation hepatitis C related hepatocellular carcinoma Patients and methods This prospective cohrt study was conducted on hepatocellular carcinoma patient, who underwent radiofrequency ablation in Tropical Medicine Department in Eldemerdash and Ain Shams Specialized Hospital, HCC clinic Ain Shams University Hospitals, Cairo, Egypt between march, 2017 and May, 2019. Data of the patient, who underwent radiofrequency ablation during the study period, were reviewed and the patients who fulfilled the inclusion criteria were enrolled into this study. The patients who fulfilled the inclusion criteria and underwent radiofrequency ablation were followed up for 12 months. Results TE revealed 28 patients with F4 and only 2 patients with F3, the mean measurement of liver stiffness was (22.45 ± 10.36) KPa. There was a significant negative correlation between LS and denovo recurrence of HCC (mean of LS in patients with complete response was 17.19 ± 3.32 and the mean of LS in patient with denovo recurrence was 36,94 ± 5.93,with the The best cut off value ≥24.65 (p value < 0.001)). There was no significant correlation between CDC, FIB4, API scores and denovo recurrence of HCC. Also it was found that the LS was significantly associated with prediction of manifestation of hepatic decompensation after RFA (means of LS in patient without manifestation decompensation after RFA (p value <0.001) .Regarding prediction of mortality, LS at cut off value > 42 .75 (p value = 0,031) was significantly associated with prediction of mortality after one year of RFA. As regard serum non invasive fibrosis indices our results showed correlation between FIB4 score and hepatic decompensation after one year of intervention (the mean of FIB4 score in patients ascites and jaundice was 6.05 ± 4.71 (p value = 0.05) ).Therewas no statistically significant correlation between CDS and API with hepatic decompensation after RFA .As regard role of serum non invasive fibrosis indices in prediction of mortality after RFA, FIB4 score, CDS and API were statistically non significant. Conclusion Our data suggest that LS measurement is a useful predictor of HCC de novorecurrence overall survival and possibility of hepatic decompensation after RFA

Tumor Pathogenesis

Orbital (slow flow) cavernous venous hemangiomas (OCVH) are the most common benign orbital tumors in adults. The c-KIT is a tyrosine kinase receptor, which is expressed on several types of cells, is thought to play a key role in tumor pathogenesis. The purpose of this study was to evaluate the presence of the receptor c-KIT in OCVH. Our retrospective study examined 16 orbital cavernous venous hemangiomas from 16 cases operated on between 2006–2016 at Emek Medical Center. The mean tumor size was 18.4 mm. Symptoms appeared between 6 months and 22 years before operation. All specimens were analyzed for the c-KIT receptor through immunohistochemistry. The c-KIT was expressed by the endothelium in all 16 preparates. Staining was strong in two cases, moderate in six, and weak in eight cases, with no statistically significant correlation between staining and tumor size (p = 0.69) or the symptom duration (p = 0.15). We conclude that c-KIT may play an important role in the pathogenesis of OCVH. This pilot study is significant in that tumor-targeted therapy such as Imatinib Mesylate and Sunitinib may have a role in treating surgically complicated cases located in the orbital apex. A large multicenter collaborative study is necessary to examine the role of c-KIT in OCVH.
