BACKGROUND: Lobular breast cancer in men is an extremely infrequent occurrence due to the lack of lobules and acini in the male breast. Such a rare case is described here. CASE REPORT: A 74-year-old patient presented with a sizeable lesion in the right breast, which proved to be a lobular carcinoma. Genetic studies excluded Klinefelter's syndrome, though revealing an interesting genetic multiformity feature. This case represented a lobular carcinoma in a genotypically male patient under no exogenous or endogenous estrogenic influence. CONCLUSIONS: The increasing number of male lobular breast cancer cases should be explored more extensively with particular emphasis placed on causally related genetic and hormonal factors.

OBJECTIVE: To assess the short-term (15-d) and long-term (12-month) effects of a school-based health and nutrition education intervention on diet, nutrition intake and BMI. DESIGN: The 12-week teacher-implemented intervention in combination with seminars organized for parents was aimed at improving children's diet and nutrition knowledge. The intervention took place between September 2007 and January 2008. The participants were randomized to two study groups, the intervention group (IG) and control group (CG), and were examined prior to the intervention on a variety of health knowledge, dietary, behavioural and anthropometric indices. The same measurements were collected 15 d and 1 year after the intervention. SETTING: All high schools in Vyronas, a densely populated district of Athens, Greece. SUBJECTS: The sample consisted of 191 students aged 12-13 years. RESULTS: Twelve months after the intervention, the programme was effective in reducing various indices in the IG compared with baseline findings (BMI: 23.3 (sd 2.8) v. 24.0 (sd 3.1) kg/m2, P < 0.001; daily energy intake: 8112.4 (sd 1412.4) v. 8503.3 (sd 1419.3) kJ/d, P < 0.001; total fat intake: 31.3 (sd 4.4) v. 35.4 (sd 4.7) % of daily energy, P < 0.001). Except for BMI, decreases in the aforementioned indices were also observed 15 d after the intervention. In addition, students of the IG reduced their weekly consumption of red meat and non-home-made meals and increased their frequency of fruit and breakfast cereal consumption. CONCLUSIONS: The beneficial effects of this nutrition education intervention among adolescents may highlight the potential of such programmes in the prevention of obesity.

The currently available genetic tests for identification of the RET proto-oncogene mutation offer the possibility of prospective successful therapy before the hyperplasia of C-cells evolve to Medullary Thyroid Carcinoma. We present our experience regarding the preventive thyroidectomy of family members with history of Medullary Thyroid Carcinoma, who were found to be heterozygote for mutant RET proto-oncogene. We have retrospectively reviewed 19 members of 6 families with history of Medullary Thyroid Carcinoma, who were heterozygote for mutant RET protooncogene and underwent prophylactic thyroidectomy. All patients included in this series were below twenty years of age. The Medullary Thyroid Carcinoma was asymptomatic and the mutation of RET protooncogene has been also documented pre-operatively in all of them. All patients had undergone total thyroidectomy, while 1 with pheochromocytoma had undergone also left epinephridectomy. Fourteen patients (73.68%) had undergone lymph-nodes resection (in 10 of them the resection was central, in 3 unilateral and in 1 bilateral). Although none of our patients suffered from hyperparathyroidism, 7 parathyroid glands have been also resected from 3 patients, while auto-transfusion has been performed in one. In all patients, preoperative measurement of the calcitonin blood levels before and after stimulation with pentagastrin has been performed.
