Stable Ozonides with Vitamin E Acetate versus Corticosteroid in the Treatment of Lichen Sclerosus in Foreskin: Evaluation of Effects on Inflammation.

BACKGROUND: Lichen sclerosus (LS) is a disease of the skin of unclear etiology that can occur in the foreskin. Topical therapy with corticosteroids is recommended, but they can have side effects. OBJECTIVES: We aimed to compare the effects of ozonides with vitamin E acetate (OZOILE) versus topical corticosteroid in children undergoing circumcision. METHOD: Twenty children undergoing circumcision were treated before surgery: 10 children with OZOILE cream and 10 with 0.1% mometasone furoate once a day for 7 days. Ten age-matched patients with LS of the foreskin without any treatment were recruited as controls. Transcript levels of proinflammatory and anti-inflammatory cytokines and e-cadherin were evaluated in removed foreskins by qRT-PCR. RESULTS: OZOILE and steroid topical treatment produced a similar reduction of TNF-α and IL-1ß mRNA levels in foreskins from patients with LS when compared to untreated patients (p < 0.001). OZOILE and steroid treatment caused an increase in the transcript levels of IL-13 and e-cadherin in the foreskin of patients affected by LS in comparison to untreated foreskin (p < 0.001). CONCLUSIONS: On the basis of our biochemical data, a randomized clinical trial might be useful to verify the actual clinical effect of OZOILE as alternative treatment to corticosteroids in children affected by LS of the foreskin.

Medical perspective in testicular ischemia-reperfusion injury.

Testicular torsion or torsion of the spermatic cord is one of the most serious urological conditions. It causes testicular injury, which potentially leads to male subfertility. The turning of the spermatic cord and spermatic structures around themselves results in biochemical and histological changes; however, following testicular detorsion, tissues undergo reperfusion that causes more severe damage than that induced by ischemia. Since the primary causes of testicular damage are reactive oxygen species production, an increase in intra-mitochondrial calcium concentration and an increased rate of cellular apoptosis, different medications may potentially be effective. It seems that several medications, experimentally and sometimes clinically, serve an adjuvant role in the cellular damage that occurs following ischemia-reperfusion. Antioxidants, calcium channel blockers, phytotherapeutical medicinals, anaesthetics, hormones and platelet inhibitors may potentially create a solid basis for an adjuvant restoring therapy and ameliorate testicular function following torsion. The current study aimed to review the relevant literature and discuss the actions of a number of molecules that may protect the testes during ischemia/reperfusion injury.

Neonatal bowel strangulation: Rare presentation of congenital diaphragmatic hernia.

We report a case of congenital diaphragmatic hernia (CDH) with perinatal bowel strangulation requiring intestinal resection. Ten hours after birth, the newborn started to be lethargic and developed bilious emesis. X-ray documented distended loops of bowel with air fluid levels in the abdomen and a gasless, non-homogeneous opacity of the left hemithorax, a right mediastinal shift and loss of the sharp left hemidiaphram line. On gastrographin enema the left colon was above the adjacent left diaphragm. Emergency surgery was performed at 16 h of age. The entire small bowel appeared reddish and compromised. After 24 h, second-look laparotomy was performed and only 25 cm of small bowel were viable. The postoperative period was uneventful. Neonatal bowel strangulation in CDH should be taken into account when estimating postnatal morbidity and mortality and, even if CDH treatment is not an emergency procedure, if gastrointestinal symptoms prevail over respiratory symptoms, surgery should be carried out without delay.

Inhibitors of apoptosis proteins in experimental benign prostatic hyperplasia: effects of serenoa repens, selenium and lycopene.

BACKGROUND: The apoptosis machinery is a promising target against benign prostatic hyperplasia (BPH). Inhibitors of apoptosis proteins (IAPs) modulate apoptosis by direct inhibition of caspases. Serenoa Repens (SeR) may be combined with other natural compounds such as Lycopene (Ly) and Selenium (Se) to maximize its therapeutic activity in BPH. We investigated the effects of SeR, Se and Ly, alone or in association, on the expression of four IAPs, cIAP-1, cIAP-2, NAIP and survivin in rats with experimental testosterone-dependent BPH. Moreover, caspase-3, interleukin-6 (IL-6) and prostate specific membrane antigen (PSMA) have been evaluated.Rats were administered, daily, with testosterone propionate (3 mg/kg/sc) or its vehicle for 14 days. Testosterone injected animals (BPH) were randomized to receive vehicle, SeR (25 mg/kg/sc), Se (3 mg/kg/sc), Ly (1 mg/kg/sc) or the SeR-Se-Ly association for 14 days. Animals were sacrificed and prostate removed for analysis. RESULTS: BPH animals treated with vehicle showed unchanged expression of cIAP-1 and cIAP-2 and increased expression of NAIP, survivin, caspase-3, IL-6 and PSMA levels when compared with sham animals. Immunofluorescence studies confirmed the enhanced expression of NAIP and survivin with a characteristic pattern of cellular localization. SeR-Se-Ly association showed the highest efficacy in reawakening apoptosis; additionally, this therapeutic cocktail significantly reduced IL-6 and PSMA levels. The administration of SeR, Se and Ly significantly blunted prostate overweight and growth; moreover, the SeR-Se-Ly association was most effective in reducing prostate enlargement and growth by 43.3% in treated animals. CONCLUSIONS: The results indicate that IAPs may represent interesting targets for drug therapy of BPH.

The combination of Serenoa repens, selenium and lycopene is more effective than serenoa repens alone to prevent hormone dependent prostatic growth.

PURPOSE: Serenoa repens is frequently combined with other natural compounds, such as the carotenoid lycopene and the essential trace element Se, to increase its therapeutic activity in benign prostatic hyperplasia. We noted that the lycopene-Se-Serenoa repens combination has greater, enhanced anti-inflammatory activity, which might be of particular interest for benign prostatic hyperplasia treatment. Testosterone administration in rats is a suitable tool for investigating hormone dependent benign prostatic hyperplasia. We performed a comparison experiment between Serenoa repens and the lycopene-Se-Serenoa repens combination on prostate growth induced in rats by testosterone administration. MATERIALS AND METHODS: Rats were treated daily with testosterone propionate (3 mg/kg subcutaneously) or its vehicle for 14 days. Testosterone administered animals were randomized to receive vehicle, Serenoa repens (25 mg/kg subcutaneously) or the combination of lycopene (3 mg/kg subcutaneously), Se (3 mg/kg subcutaneously) and Serenoa repens for 14 days. The rats were sacrificed and the prostate was removed for analysis. RESULTS: Lycopene-Se-Serenoa repens was more effective than Serenoa repens alone for decreasing prostate weight and hyperplasia, augmenting pro-apoptotic Bax and caspase-9, and blunting anti-apoptotic Bcl-2 mRNA. Lycopene-Se-Serenoa repens also markedly decreased epidermal growth factor and vascular endothelial growth factor expression. CONCLUSIONS: The data indicate that the lycopene-Se-Serenoa repens combination is superior to Serenoa repens alone for decreasing hormone dependent prostatic growth.
