[Treatment of thyroid neoplasms and proposed therapeutic plan].

Thirty-seven patients with thyroid cancer were treated at 1a Clinica Chirurgica of Parma between 1962 and 1970. Fourty-five per cent of tumors were papillary, 24 per cent follicular, 2 per cent medullary, 9 per cent anaplastic. Surgery combined with ormonal therapy formed the commonest treatment. Eighty-five per cent of the patients with papillary carcinoma 70 per cent with follicular and 33,3 per cent with anaplastic carcinoma survived for 10 years. This present series indicates that total thiroidectomy combined with ormonal therapy influences the survival time, confirms the prognostic value of histology and shows that papillary node metastases do not prejudice survival.

Immediate operative fitting of upper limb prosthesis at the time of amputation.

Three patients are described--2 with an above-elbow amputation and 1 with a through-wrist amputation--in whom a temporary prosthesis was applied on the operating table and in all of whom function was rapidly established. The patients did not become one-handed, with the result that they have all continued to wear their prosthesis throughout their working hours and use their artificial hand for all everday functions. The value of this technique in making the patient accept the prosthesis and therefore to make full use of it suggests that this procedure should be more widely applied in patients who require upper limb amputation.

A feasibility study using polychemotherapy (cisplatin + vindesine + dacarbazine) plus interferon-alpha or monochemotherapy with dacarbazine plus interferon-alpha in metastatic melanoma.

AIMS AND BACKGROUND: This trial evaluated the feasibility and tolerability of an immunochemotherapeutic approach that uses cisplatin, vindesine, and dacarbazine (DTIC), or only DTIC, in combination with interferon alpha-2a (IFN-alpha), in patients with metastatic melanoma, considering the significant toxicity of several different regimens used up to now. METHODS: Between May 1995 and September 1997, 51 melanoma patients (50 of whom were assessable) entered a multicentric trial and were randomized to receive cisplatin (30 mg/m2 daily for 3 days) + vindesine (2.5 mg/m2 only day 1) + DTIC (250 mg/m2 daily for 3 consecutive days) + IFN-alpha (3 MIU i.m. 3x/wk continuously) (CVD arm) versus DTIC (800 mg/m2 day 1) + IFN-alpha (3 MIU i.m. 3x/wk continuously) (DTIC arm). The chemotherapy was recycled every 21 days. Patient reevaluation was performed every two cycles, and the treatment was continued in case of objective response or stabilization of disease. RESULTS: We observed 3 complete responses, 2 partial responses and 5 stable diseases in the CVD arm, and 2 partial responses and 4 stabilizations of disease in the DTIC arm. CONCLUSIONS: We conclude that these chemotherapeutic regimens are well tolerated regimens with modest toxicity. Future trials will be conducted associating the CVD regimen with biological response modifiers (IFN, IL-2) in order to improve the results.

[Laboratory diagnosis: correlated health and environmental risks].

Method description and initial results of a study to assess risks to health sector workers and environment due to chemical agents used and waste products generated in diagnostic clinical chemical laboratories, and image diagnostic testing. A survey was conducted of the methods and agents used and their toxicological classification, the number of workers exposed and an analytical profile of the waste produced. The assessment of risk to workers was based on cytogenetic tests (chromosome aberrations and micronuclei); the assessment of environmental risk from waste disposal was based on tests on plant systems.

[SARS: diagnosis, therapy, and especially prevention].

The main purpose of this review is to analyze some aspects of the severe acute respiratory syndrome, SARS, in order to obtain useful data to suggest preventive actions to reduce the spreading of the disease. Many elements have been examined to reach some conclusions and to allow an updated discussion. Surgical masks protect more the patient than the caregiver. Simple or double surgical masks may be useful, as double gloving protects the hands of the surgical personnel against percutaneous transmission of HIV eventually present in contaminated blood. The frequent substitution of the external masks with a new one will improve the filtering activity against droplets produced by cough or sneezes of the patient. The use of respiratory masks may be suggested in hospitals or in restricted ventilated areas where, even if coronavirus variant is considered an environmental contaminant more than a respiratory risk, droplets nuclei may persist in the air and add consistent dangers to the heath-care givers. Considering that large and medium droplets may infect floors and surfaces, in addition to gloves, gowns, masks and eyes protection, the available list of viral and bacterial factors implicated in SARS ethiology suggests a better hand antisepsis using frequently the alcohol based gels (containing an high percentage of emollients substances), if available. A liquid soap with triclosan can also be used, if the health-care workers compliance to hand washing increases, as expected in this explosive situation. On the basis of the results of some experimental data, the environmental disinfection may be effected with ethyl alcohol 70% in water. Disinfection of floors or larger surfaces may be obtained with chlorine compounds solutions, after an accurate pre-cleaning. When corrosion, bleaching or gas production have to be avoided, chlorine compounds may be substituted by phenolic detergent disinfectants.

[Alkylphenols in the environment: a risk for human health?].

Endocrine Disrupting Chemicals (ECD) are a class of chemical compounds widely utilized for many industrial and civil applications and, consequently, widely diffused in the environment. Due to their chemical-physical characteristics, ECD may interfere with several endocrine functions in humans. Alkylphenols (APs), mainly produced by biodegradation of alkylphenols polyethoxylates surfactants, are a relevant group of ECD, both for their environmental diffusion and demonstrated estrogenic activity. Aim of this paper is to assess the potential risk of exposure to APs for humans, on the basis of the available data in literature concerning APs: environmental levels, accumulation in sediments and biota, toxicological effects on experimental animals.

[Antisepsis and disinfection in emerging and re-emerging viral diseases].

Prevention and therapy of emerging and re-emerging viral diseases may be inefficient due the inavailability of specific vaccines, active chemotherapic drugs, acceptable pesticides, and vector control measures. To reduce contact spreading of viral infections, some biocides, as chlorine compounds or phenolic compounds, associated with detergents, may assume a leading position as safe substances with antiviral properties for the environmental decontamination. Detailed instructions on their use may be introduced in future guidelines related to emerging and re-emerging viral diseases.

[Gastro-esophageal reflux in childhood. When to operate?].

Gastroesophageal reflux has been well described in children as the cause of a variety of symptoms from nutritional to respiratory problems. If the regurgitation and vomiting are very common symptoms in newborns, their persistence after the first months of life will result in pathological entity leading to complications as esophagitis, failure to thrive, respiratory problems. The purpose of this article is to point out the functional and anatomical implications maintaining gastroesophageal reflux in children and the correct indications for surgery.
