Comparing GnRH agonist long protocol and gnrh antagonist protocol in outcome the first cycle of ART

Purpose  

This prospective study evaluated the efficacy of gonadotropin-releasing hormone (GnRH) antagonist protocol in comparison with the GnRH agonist protocol in the first cycle of assisted reproductive technique (ART).     

Expression of p53 in aggressive and non-aggressive histologic variants of basal cell carcinoma

Basal cell carcinoma (BCC) generally has an indolent course but a subgroup of BCCs tends to grow aggressively into deep tissues and even metastasize. Although studies have shown a positive correlation between mutations in the tumor suppressor gene p53 and aggressive behavior in epithelial tumors, the results for BCC are conflicting. We aimed to determine whether there is any relationship between p53 expression in BCC and histopathologic subtype of the tumor.Thirty-three formalin-fixed BCC tissue samples were examined at Hazrat-e Rasool University Hospital, Tehran, Iran, from March 2003 to April 2004. Tumors were categorized as aggressive (infiltrative or morpheic) and non-aggressive (nodular or superficial) based on histopathological examination of hematoxylin and eosin sections. p53 expression was demonstrated by immunohistochemical staining using the monoclonal anti-p53 antibody (PAb240) and results were reported using a semiquantitative score. Expression of p53 was compared between aggressive and non-aggressive tumors. All of the 11 aggressive tumors exhibited nuclear staining in more than 50% of the tumor cells. In the 22 non-aggressive tumors, less than 50% of cells showed positive staining. p53 immunoreactivity was significantly higher in aggressive BCCs than non-aggressive ones (x(2) test; p < 0.01). No correlation was found between p53 expression and the age of the patient or site of the tumor. History of childhood radiotherapy correlated positively with higher levels of p53 expression. We conclude that expression of p53 might be used as a marker to predict the aggressiveness of BCCs.     

Scabies presenting with bullous pemphigoid-like lesions

A wide range of clinical manifestations may be seen in scabies, from classic pruritic papules and burrows to secondary features such as impetigo. Bullus lesions are a less frequent. Twenty cases of scabies presenting with bullae have been reported so far in the medical literature. Differentiating this subtype of scabies from the immunobullous disease bullus pemphigoid is a diagnostic challenge. A 42-year-old man was referred to our dermatology outpatient clinic with 3-month history of severe pruritus and tense blisters affecting mainly the lower trunk, arms and legs. An initial biopsy was suggestive for bullous pemphigoid. Close physical examination revealed small excoriated papules and a few burrows on borders of the hands and wrists. Skin scraping of the lesions on wrists was positive for Sarcoptes scabiei. Another biopsy specimen from a recent blister revealed subepidermal bullae with fibrin and inflammatory cells, particularly eosinophils. Direct immunofluorescence exam was negative. The patient was treated with lindane lotion followed by crotamiton cream with near complete resolution of the lesions. Scabies must be considered in patients presenting with recent onset of unexplained pruritic bullous lesions. Biopsy and immunofluorescence studies together with skin scrapings for Sarcoptes scabiei could help to differentiate these cases from bullous pemphigoid. Antiscabietic treatment results in resolution of bullous lesions in the affected patients.

The effect of ovarian cyst aspiration on IVF treatment with GnRH

Objective  

The formation of cysts during IVF treatment may negatively influence the outcome. The aim of this study is to compare conservative management versus aspiration for functional ovarian cysts before ovarian stimulation for ART.     

Long-term association of nut consumption and cardiometabolic risk factors

Background and aimsLong-term associations between nut consumption and cardiometabolic risk factors are not well known. We investigated the relationship between nut consumption and cardiometabolic risk factors including dyslipidemia, hypertension, diabetes mellitus (DM), and obesity in a cohort of Iranian adults.Methods and resultsThe study was conducted within the framework of the Isfahan Cohort Study on 1387 healthy participants. The participants were followed up for 12 years. A validated food frequency questionnaire was completed, and anthropometric measurements, blood pressure, and fasting serum lipids and blood sugar were evaluated in three phases. Mixed-effects binary logistic regression was applied to examine the associations between nut consumption and cardiometabolic risk factors. The participants were classified according to the tertiles of nut consumption as cut-points, and associations were evaluated between the thirds of nut intake.Subjects in the last third were less likely to have hypercholesterolemia [OR (95% CI): 0.76 (0.60–0.97)], hypertriglyceridemia [OR (95% CI): 0.74 (0.58–0.93)], and obesity [OR (95% CI): 0.79 (0.50–0.98)] but more likely to have DM [OR (95% CI): 1.85 (1.27–2.68)] than those in the first third. However, after adjustment for various potential confounders, the associations remained significant only for obesity [OR (95% CI): 0.67 (0.48–0.94)] and DM [OR (95% CI): 2.23 (1.37–3.64)].ConclusionAfter adjustment for potential confounders, we observed an inverse association for nut consumption and obesity but positive association for DM and nut intake. On the basis of our findings, it is suggested that incorporation of nuts into people's usual diet may have beneficial effects for individuals with lower risk such as subjects without DM.
