Early onset of puberty in young girls: an Italian cross-sectional study.

BACKGROUND: International literature and clinical practice have referred to Marshall and Tanner data to define the physiological age at onset of puberty. A study in the United States (1997) showed an anticipation in pubertal onset, whereas several European studies did not confirm this trend. AIM: To describe the onset of secondary sexual characteristics in a large Italian population of girls and to compare it to reference literature data. SUBJECTS AND METHODS: A cross-sectional study on 7311 2-14-yr-old girls who spontaneously requested a clinical evaluation for routine health check-up or acute illness by family pediatrician's offices in a northern Italian region (Lombardy), between September 2005 and November 2006. Trained family pediatricians performed a complete physical examination; pubertal status was evaluated following Tanner's criteria; breast development was assessed by palpation. RESULTS: Mean age of thelarche (B2), pubarche (PH2), menarche were 9.75, 10.09, and 12.49 yr, respectively. The prevalence of B2 and PH2 at ages 7-7.99 was 5.9% and 5.6%, respectively, at ages 8-8.99 was 15.5% and 13.8%, respectively. Mean time lapse from B2 to B3 and B2 to menarche was 1.46 and 2.74 yr, respectively. Mean age at menarche of our population and their respective mothers was almost identical. CONCLUSIONS: Our population presented earlier clinical signs of pubertal development than those defined by Marshall and Tanner. Mean age of menarche was not different in comparison to the previous generation. A different progression of pubertal development was found, in which the shift to B3 may have more clinical relevance.

[Experience of 10 years with the surgical treatment of lung cancer in elderly patients]. / Esperienza di dieci anni nel trattamento chirurgico del cancro del polmone nel paziente anziano.

The surgical treatment of lung cancer in elderly patients is correlated with a lot of complications that in most cases are cardiopulmonary type; for this reason, in past times these patients were left out of the surgical treatment. Today, the progress of surgical, diagnostic and anesthetic techniques permit to execute pulmonary resections in patients older than 70 years too. The aim of this study is to evaluate postoperative complications and long-term and long-term survival in patients under and over the age 70. Between January 1990 and June 2000 we have assessed 172 patients with lung neoplasm. We have divided patients in two groups: those younger than 70 years of age (group 1, n = 119) and those older than 70 years of age (group 2, n = 53). Postoperative mortality for group 2 was 7.5% and for group 5.1%. The overall postoperative complication rate for group 2 was 30.2% and for group 1 10.9%. Within group 1 main complications have been of surgical type (61.5%) while in group 2 medical type (cardiopulmonary), with higher frequency in patients ASA 3 or ASA 4. The mortality at 12 months for non-neoplastic causes was 10.2% for group 2 and 2.5% for group 1. On the contrary, the mortality at 12 months for neoplastic causes was 8.2% for group 2 and 6.7% for group 1. We haven't noticed an important correlation between the extension of the resection and the recurrence of disease. The survival at 3 years was 46.5% for group 1 and 41% for group 2 and associated with neoplastic causes.

[2 cases of a true splenic cyst]. / Due casi di cisti splenica vera.

The nonparasitic cysts of the spleen are uncommon and their pathogenesis has not been precisely determined. Often asymptomatic, the cysts are recognised during an investigation of the abdomen for other pathological conditions; if present, the symptoms are not specific and mild. The authors report two cases of non parasitic cysts of the spleen: in the first case the onset of the disease was insidious, with dyspeptic symptoms and epigastric pain; in the second case, the cyst was initially interpreted like a metastatic localisation of a an abdominal melanoma.

[Total thyroidectomy technique: suggestions and proposals of surgical practice]. / Tecnica della tiroidectomia totale. Suggerimenti e proposte di pratica chirurgica.

Total thyroidectomy at present depicts a diffuse surgical procedure in the management of benign and malignant disease of thyroid gland. It is followed by a low incidence of iatrogenic damages (nervous lesions or permanent hypoparathyroidism), just like subtotal thyroidectomy and lower than surgery for nodular recurrences. Authors present the surgical technique they follow to perform total thyroidectomy, used in over 400 cases of benign thyroid diseases operated since 1986. The most important points of this surgical procedures are represented by exposure and sparing of inferior laryngeal nerve and by preservation of parathyroid function. Parathyroid glands can be exposed to direct surgical trauma but, more often, they are injured by damage of their vascular supply. To avoid this complication, vascular ligations of inferior thyroid artery have to be done never on the trunk of the artery, but on its branches just near the glandular capsula. Sparing of inferior laryngeal nerves comports the exposure of this structure for all its cervical course especially in the terminal edge, when the nerve is nearest to the gland. Systematical application of illustrated procedure has produced no operative mortality, no inferior laryngeal nerve permanent palsy, transient hoarseness in 0.5%, and transient symptomatic hypocalcemia in 2.7%.

[Submandibulectomy in the treatment of pathology of the submandibular gland: our experience 1970-1995]. / La sottomandibulectomia nel trattamento delle patologie della ghiandola sottomandibolare: nostra esperienza 1970-1995.

Submandibular gland excision is proposed in the treatment of neoplastic and non neoplastic diseases; this surgical procedure can be performed by transoral or transcervical approach. The aim of the study is to demonstrate that cervical approach must be preferred because it is safer and allows a wider exposition of the surgical field. From 1970 to June 1995, 54 patients (47 with chronic sialadenitis, 7 with benign tumors and 7 with malignant tumors) were submitted to excision of the submaxillary gland. Of the 54 resections performed, 2 were completed with "functional" cervical lymphadenectomy and 1 with Radical Neck Dissection in pts. with malignant neoplasms. There were no postoperative deaths; complications occurred in 1 patient (1/54 = 1.8%) as a iatrogenic permanent lesion of the maxillary branch of the facial nerve (in detail 0/47 patients with benign disease and 1/7 (14.7%) patients with malignant disease). The cervical approach for the resection of the submaxillary gland is preferred to the transoral approach for the lower risk of iatrogenic lesions of the lingual and hypoglossal nerves and the possibility of curative resections in case of malignant neoplasms. A regulated and experimented technique through the cervical approach also lowers the risk of a lesion of the maxillary branch of the facial nerve.

[Riedel's thyroiditis: a case report and review of the literature]. / La tiroidite di Riedel: descrizione di un caso clinico e revisione della letteratura.

Riedel's thyroiditis is a very rare disease of unknown aetiology, occasionally associated with retroperitoneal and mediastinal fibrosis. It is a benign condition, but may be confused with an anaplastic carcinoma of the thyroid. The differential diagnosis with anaplastic carcinoma is assured only by intraoperative biopsy. The Authors report a clinical case: symptoms were a progressive enlargement of the thyroid gland, left recurrential palsy, dyspnoea and dysphagia. The surgical treatment was total thyroidectomy, performed with bilateral neurolysis of recurrent nerves. The patient was also under adjuvant corticosteroid treatment.

[Paraganglioma in the case records of the III Surgical Clinical Institute]. / I paragangliomi nella casistica dell'istituto di III Clinica Chirurgica (1970-1995).

Cervical paragangliomas are uncommon benign or malignant neoplasms, originated from the stem cells of the neural crest. Up to date it is still not easy to define properly their biological behaviour, the possible multicentric location and the association with Multiple Endocrine Neoplasias. After a wide review of recent diagnostic, pathological and clinical notions, the Authors report their experience, from 1970 to 1995, of 10 patients affected by sporadic paraganglioma and 1 by familial multicentric neoplasm localized on carotid bodies of both sides, left vagus nerve and left hypoglossus nerve. All patients but one were treated by a curative resection of the neoplasm; in one case only an explorative laparotomy was possible because of the visceral and vascular involvement.
