Cancer of the lung is becoming increasingly common. In the U.S., it has the highest mortality of the neoplastic diseases, well ahead of cancer of the colon and rectum. Surgical and/or complementary management is poorly effective because it comes too late. Early diagnosis and treatment are essential, therefore. Preclinical diagnosis may be possible radiographically in certain fortunate cases, but this is never an early diagnosis. The latter is only possible through active bronchial cytology (bronchial brushing, selective washing, PBS) during and after flexible fibrobronchoscopy, which can be carried out under local anaesthesia at the outpatient level and causes very little distress to the patient. Data from a personal series are cited in support of the view that cytodiagnosis should be routinely employed in subjects at high risk (heavy smokers, persons with chronic bronchitis, emphysema, etc.).

[Functional changes in the esophagus and action of pentagastrin on the competence of the lower esophageal sphincter (LES) after esophageal vagotomy].

In pursuance of an investigation of oesophageal physiopathology, a study has been made of the problem of the functional regulation of the inferior oesophageal sphincter in the light of new findings. Experiments carried out on six dogs made it possible to study functional modifications of the oesophagus after vagotomy, completing the technique by administering pentagastrin for the first time in vivo. Radiological and mano metric controls showed in the post-operative period a dilated oesophagus with a fall, in the lower third, of normal pressure values that did not undergo change, unlike what happened in the non-denervated oesophagus after administration of pentagastrin. The results obtained show that the integrity of the nervous structures is not only necessary for the perfect coordination of oesophageal peristalsis, but vital for normal functional response of the inferior oesophageal sphincter, since gastrin action is always mediated by release of acetylcholine by the post-gangliar vagal nerve endings.

Lipoid proteinosis: a case report.

An 8-year-old Italian boy, born to consanguineous parents, with clinical, histopathologic, and ultrastructural findings of lipoid proteinosis is reported. The main signs of the syndrome-papulonodular, hyperkeratotic and verrucous lesions distributed over the skin of the head and extremities, hoarseness, and dysphagia-were present in the child. The mother had papulonodular lesions on her hands and also complained of slowness in healing.

Congenital bone malformations in patients with neurofibromatosis type 1 (Nf1).

To address the prevalence of congenital bone malformations in neurofibromatosis type 1 (Nf1; compared with Nf1 bone anomalies and tumors), we studied the Nf1 population of 135 children (70 boys, 65 girls) seen at the neurofibromatosis clinic, University of Catania, Italy, in the period 1990 through 1996. Twelve (8.8%) of the 135 children had congenital bone malformations: unilateral or bilateral postaxial polydactyly type A (n = 1) and type B (n = 1), bilateral postaxial polydactyly type A in association with preaxial polydactyly type 1 (n = 1) and bilateral preaxial polydactyly (n = 1); clynodactyly (n = 1); multiple segmentation anomalies of the vertebrae (n = 6), and complex costovertebral anomalies (n = 1). We found a higher frequency of polydactyly (2.9%) in comparison to that in the general population (0.014-0.12%) and in our national (0.027%) and regional (0.066%) population, and a higher frequency of vertebral (5.1%) and costovertebral (0.7%) malformations. This is the first study to state the overall prevalence of congenital bone malformations in an Nf1 population. Interestingly, polydactyly (postaxial type) and Nf1 was previously reported only once.

Lung microcytoma: a multidisciplinary therapeutic approach.

This report is of 26 patients diagnosed with microcytoma of the lung in stages I, II, and IIIa. All patients received surgical treatment as well as postoperative chemoradiotherapy when indicated by stage. Mean survival rates were 16 months for stage 1, 10 months for stage II and 6 months for stage IIIa disease. For many years surgery was considered contraindicated in the treatment of pulmonary microcytoma. Now a multidisciplinary approach is being used in which surgery has a crucial role. Microcytoma of the lung has a poor prognosis due to its early metastasis and rapid growth. It is crucial to have early diagnosis and accurate, consistent staging as the basis for treatment. A review of literature shows that the use of surgery, chemotherapy and radiotherapy are all important in treatment of microcytoma. Chemotherapy is successfully utilized preoperatively to improve local control, decrease neoplastic mass, induce histological regression and as postoperative adjuvant therapy. Radiotherapy has been shown to be effective preoperatively to reduce local mass and prophylactically for cerebral metastasis. Surgery is crucial to irradicate the neoplastic mass, improve staging accuracy, decrease the possible selection of neoplastic clones resistant to postoperative therapy, decrease local recurrence and allow less aggressive chemoradiotherapy. We feel the most effective protocol for pulmonary microcytoma includes preoperative chemotherapy and radiotherapy when indicated followed by surgical intervention and finally successive adjuvant therapy. The limited number of our cases does not consent a statistically significative conclusion. Our data confirm the importance of the surgical procedure in stages I and II, where according also to other authors, the best results are obtained. Surgical indication in stage IIIa is still discussed due to precocius lymphnode dissemination that significantly affects long-term survival.

[Early relapse of herpes simplex encephalitis. Clinical and therapeutic implications].

A case of Herpes simplex virus encephalitis (HSVE) is reported in a 5 year old boy, who relapsed twice during the acute phase of the disease. The second relapse was completely cured by increasing the daily treatment with acyclovir to a dosage of 60 mg/kg intravenously for two weeks and 30 mg/kg by mouth for a further week. The full disappearance of the symptoms and the regression of cerebral lesions could be correlated to a prompt diagnosis and to the dosage of acyclovir employed, higher than that suggested for diseases caused that was by other members of the Herpes virus family.

Effectiveness of forced rehydration and early re-feeding in the treatment of acute diarrhoea in a tropical area.

BACKGROUND: The administration of oral re-hydration solution (ORS) via continuous infusion through a nasogastric (NG) tube and early refeeding facilitates delivery in hospitalised children and the return back home. METHODS DESIGN: the observation was made during a one-year stage in the Camillian Medical Centre (CMC) of Ouagadougou in Burkina Faso. 4,131 infants and children under 5 years old, affected by acute diarrhoea and severe dehydration (loss of weight > 10%) were studied. Those children having difficulties for oral re-hydration were hydrated by continuous infusion through naso-gastric (NG) tube; the NG tube was put in by the nurses and connected to a 500 ml bottle, in which a mixture of glucose and electrolytes was dissolved according to the formula (glucose 20 g + NaCl 3.5 g + NaHCO3 2.5 g KCl 1.5 g in 1 litre of water). The infusion rate was 20-30 drops/minute. No sedative or anti-emetic drug was given, unless in the presence of uncontrolled vomiting. At the end of infusion, flour of millet (60%), soy bean (20%), peanut butter (10%), sugar (10%) and salt (1%) was administered and continued at home or in the nearby areas available for the night. RESULTS: After 4-5 hrs of infusion 3,717 children (90%) showed a significant gain of weight, although the weight prior to the acute event preceding hospitalisation was never reached during their stay at the CMC. Only 413 children (10%) required a longer period of forced infusion: at the end of the day, however, they were fed with this flour. CONCLUSIONS: A simple strategy, based on a NG infusion plus an oral administration of flour has proven safe and effective in encompassing those difficulties encountered in the treatment and prevention of dehydration in developing countries where the therapy, in children affected by diarrhoea, still represents a major daily occupation.

Hyperthyroidism and concurrent thyroid carcinoma.

In the last twenty years, medical studies have reported a significant increase in thyroid neoplasms among patients with hyperthyroidism. Aim of the present work is to reconsider the real incidence of this not uncommon association and to establish a model for surgical treatment of hyperthyroidism for a possible concurrence with thyroid carcinoma. At the Department of Surgical Sciences and Applied Medical Technologies "La Sapienza" Rome's University, during the period 1994 to 1999, an homogeneous group of 82 patients was surgically treated for hyperthyroidism. Of our patients, fifty-four (66%) had a "multinodular toxic goiter" (MTG), twenty (24%) a "functional autonomous nodule" (FAN) while the remaining patients were affected by Graves' disease. The surgical procedures adopted were: 1) total extracapsular ipsilateral lobectomies and isthmectomies in sixteen patients with FAN; 2) total extracapsular thyroidectomy in all patients with MTG and with Graves' disease and in the remaining four patients with FAN after a long time treatment with thyrostatic drugs. On six (7%) of our patients we found out a thyroid carcinoma: five with MTG and one with Graves' disease. However, no association with thyroid carcinoma was observed in anyone with FAN. The correct treatment of thyroid surgical diseases is a single definitive operative approach. The procedure must be a total thyroidectomy in MTG and Graves' disease. However, in patients with FAN it's possible, after careful evaluation, to carry out a total extracapsular ipsilateral lobectomy with isthmectomy, justified by the normal morphology of the remaining thyroid tissue. It is always possible, in these cases, a subsequent complete exeresis if a carcinoma is present in the removed lobe.

Therapeutic approach of carcinoid tumours of the lung.

In the carcinoid tumours of the bronchopulmonary tract surgical resection is still the primary goal. Many problems are, however, unclear: the extent of resection, formal lymph node dissection or not, the role of Video-Assisted Thoracic Surgery (VATS) and of the multidisciplinary approach. In the Department of Surgical Sciences and Applied Medical Technologies, "La Sapienza", Rome's University, from 1969 to 1994, we observed 18 patients with carcinoid tumours of the lung: 13 typical carcinoid (TC) and 5 atypical carcinoid (AC). In our series, the choice of therapeutic procedure was made on the basis of histological criteria and TNM classification. We performed 3 conservative and 10 extensive resections on typical carcinoid and 5 extensive resections on atypical carcinoid tumours. In our series VATS played a minor therapeutic role. Formal lymph node dissection was carried out on all our patients except in the cases of those with typical carcinoid tumours without enlarged hilar and mediastinal lymph nodes. The efficacy of adjuvant chemotherapy in carcinoid tumours treatment is controversial and will be confirmed by further trials. In bronchial carcinoid tumours the long-term prognosis is excellent. In our series the ten-year survival rate is 77 per cent in typical carcinoid and 40 per cent in atypical carcinoid cases.

Surgical treatment of differentiated microcarcinomas of the thyroid.

Thyroid microcarcinomas (TMC) are histologically malignant diseases, despite their limited dimensions and non-aggressive behaviour; frequent multifocality of the disease and local recurrence is really possible after conservative resection. Modern therapeutic approaches to thyroid microcarcinoma include both radical surgical treatment, influenced by the frequent locoregional diffusion of TMC, consisting of a total thyroidectomy with an eventual central and/or functional unilateral lymphadenectomy, depending on the clinical evidence of lymh node metastases and conservative treatment based on more limited resections which take into account the slow clinical progression of this type of tumour. The aim of our work is to examine the therapeutic guidelines for surgical treatment of TMC which, in our experience, are closely dependent on clinical presentation type. From 1991 to 2000, more than 400 patients with thyroid disease were referred to the Department of Surgical Science and Applied Medical Technologies "F. Durante". Threehundred-seventythree patients received surgical treatment: in 311 patients a benign disease was diagnosed, while in 62 neoplasia was present. In total we observed 30 TMC, consisting of 28 papillary and 2 follicular microcarcinomas. On the basis of clinical presentation we divided patients in three groups: A--patients with a clinically suspicious neoplastic lesion before surgical treatment; B--patients in whom histological diagnosis of cancer was "incidental" after an operation performed for benign disease; C--patients in whom a neck lymph node metastases were clinically found before diagnosis of an "occult" papillary carcinoma in the thyroid gland. 27 total thyroidectomies and 3 conservative resections, that required successive total exeresis, were performed. In 5 cases a central neck lymph node dissection was carried out and in 5 + 1 cases functional modified lateral neck dissections was deemed necessary. Our data suggest that an evaluation of tumor's malignancy cannot be carried out on the basis of its dimensions alone. Indeed, biological aggressivity, whether local or at a distance, is a prerogative of both large and small tumours. Therefore a microcarcinoma must be considered a full-blown form of thyroid cancer and as such must be treated. Total thyroidectomy may be followed by identification of possible local metastases. "Whole body" scintigraphy allows to identify and treat with radioiodine therapy, possible recurrent lesions. Therefore in conclusion, total resection is not only a useful, but also a necessary treatment for the correct diagnostic and therapeutic follow-up of these patients.
