Short-term reproductive prognosis when no cause can be found for recurrent miscarriage

Summary. The short-term reproductive prognosis of recurrent miscarriage for which no cause was found has been evaluated in 95 couples investigated between 1980 and 1986 at the First Obstetric and Gynaecological Clinic of the University of Milan. The actuarial overall 3-year livebirth delivery rate was 64%, increasing constantly with time. The reproductive success rate decreased with the number of previous miscarriages from 80% in women with two, to 60% with three and 46% with four or more miscarriages. No effect of age and socio-economic status emerged. There was a positive association between the number of previous miscarriages and the risk of miscarriage in the next pregnancy. Compared with women with two miscarriages the relative risk of another miscarriage was 2·3 for those with three previous miscarriages and 5·0 for those with four or more (χ²₁ for trend adjusted for age = 5·2, P = 0·02).     

Strong association between an HLA-DR antigen and thyroid carcinoma

A group of 20 patients affected with thyroid carcinoma, all from Southern Italy, was typed for HLA-A,-B,-C and -DR antigens. Sixteen of them (80%) typed for DR1, while in the control group (120 unrelated healthy individuals from the same region) only 22 (18.3%) shared the same antigen ( x ²2 = 32.96). The data indicate a highly significant association between the HLA-DR1 gene and the thyroid carcinoma.     

Melanoacanthoma Simulating Pigmented Spitz Nevus: an Unusual Dermoscopy Pitfall

BACKGROUND: The starburst pattern is the dermoscopic hallmark of pigmented Spitz nevus, although it has been rarely observed in melanoma as well. OBJECTIVE: To describe a case of melanoacanthoma simulating pigmented Spitz nevus. MATERIAL AND METHODS: Clinical, dermoscopic, and histopathologic examinations were performed for the occurrence of a 4-mm pigmented skin lesion on the hip of a 38-year-old Caucasian woman. RESULTS: Dermoscopy examination of the lesion disclosed a stereotypical starburst pattern characterized by pigmented streaks symmetrically distributed at the periphery. A preoperative diagnosis of pigmented Spitz nevus was made, and the lesion was excised. However, subsequent histopathologic examination revealed a melanoacanthoma. CONCLUSION: The starburst pattern, although diagnostic for pigmented Spitz nevus, can be rarely observed in other benign or malignant pigmented skin lesions. Accordingly, all lesions in adults exhibiting a starburst pattern or other spitzoid features should be excised for histopathologic evaluation.
