[Correlative evaluation of electrocardiographic changes and spirometric parameters in pulmonary cardiopathy secondary to chronic obstructive bronchopneumopathy].

EKG is not considered a sensitive procedure for diagnosis of chronic pulmonary heart disease (CPHD). We performed a correlative study between EKG signs and spirometry in chronic obstructive pulmonary disease (COPD). Fifty-six consecutive in-patients (M 52, F 4, age 59.1 +/- 13.1 yrs) with COPD and echocardiographic/roentgenologic signs of right ventricular enlargement were studied. An EKG score system (0-6) was developed considering: 1) AQRS greater than or equal to 90 degrees; 2) P waves greater than or equal to 2.5 mm; 3) R wave V1 greater than or equal to 7 mm or R/S V1 greater than or equal to 1; 4) R/S V5 less than or equal to 1; 5) RV strain pattern; 6) RBBB. Significant (p less than 0.01) linear correlations were observed between: a) AQRS vs FEV1 (r = -0.59); b) AQRS vs FEV1/FVC% (r = -0.61); c) R/S V5 vs FEV1, (r = +0.38); d) EKG score vs FEV1 (r = -0.42); e) EKG score vs FEV1/FVC% (r = -0.40). Significant relationship between EKG score and spirometry suggests that this criterium can be useful for a more reliable ecg diagnosis of CPHD.

[Persistence of the right venous sinus valve simulating a right atrial myxoma in a case of total anomalous pulmonary venous return. Echocardiographic, anatomo-clinical and surgical aspects].

A case of persistence of the right venous sinus valve that on echocardiographic examination simulated right atrial myxoma is reported in a patient with total abnormal pulmonary venous return in the coronary sinus. Echocardiography showed a mobile, pedunculated mass present in systole in the right atrium that shifted to diastole in the right ventricle, highly suggestive of right atrial myxoma. The right ventricle also showed a volume overload and a space without echoes behind the left atrium. A membrane was encountered in the right atrium at surgery. This was removed and the venous return corrected.

Chemotherapy of advanced head and neck squamous carcinoma with cisplatin, fluorouracil and bleomycin administered in an outpatient schedule.

From May 1983 to September 1984, 48 consecutive patients with locally advanced, recurrent and/or metastatic head and neck squamous carcinoma were treated with cisplatin 60 mg/m2 i.v. on day 1, fluorouracil 10 mg/kg i.v. push from day 1 to day 4 and bleomycin 10 mg/m2 i.v. from day 1 to day 4, every 3 weeks. In the 44 evaluable patients complete remission was observed in 4, partial remission in 9, stable disease in 19, and progression in 12, for a 29.5% response rate. When the analysis was limited to the 21 patients with PS greater than 70 and no previous chemotherapy or radiotherapy, the response rate was 48%. Toxicity was acceptable, and no treatment related deaths occurred. Overall median survival (all eligible patients) was 7 months. Although further studies with this combination in poor risk patients (previously treated or with PS less than 70) do not appear to be indicated, a more accurate assessment in good risk patients might be warranted.

Secondary laryngeal tumors. Report of seven cases with review of the literature.

Laryngeal metastases are uncommon, particularly if we consider only secondary involvement from the remote primary neoplasm, via lymphohematogenous dissemination. In the 21-year period from 1966 to 1986, only seven cases of secondary laryngeal cancers were observed at the Department of Otolaryngology of Padua (Italy) University. A review of the world literature resulted in the identification of 113 previously reported cases. Cutaneous melanoma is the neoplasm most frequently metastasizing to the larynx, but adenocarcinoma may also often occur, especially from renal origin. A correct differential diagnosis from primary laryngeal cancer is most important. Identification of tumor location beneath intact mucosa, use of particular biochemical and histochemical stains, and electron microscopy may assist in establishing the presence of a metastatic growth. The prognosis is almost generally unfavorable because laryngeal involvement often occurs with metastases to other organs.

Perioperative lumbar injection of Ringer's lactate solution in chronic subdural hematomas: a series of 100 cases.

A series of 100 patients underwent surgical treatment for chronic subdural hematomas between 1979 and 1987. The procedure consisted of craniectomy with a 30-mm trephine, irrigation and drainage of the hematoma, laceration of the outer and inner membranes, and lumbar intrathecal injection of Ringer's lactate solution for immediate cerebral reexpansion (average injection, 130 ml). This technique gave the following results: 2% mortality, 2% moderate morbidity, and 96% recovery. The recovery of the patients was rapid, and good outcome was achieved in Grade 3 and Grade 4 cases (Markwalder's classification).

Ebstein's malformation of the mitral valve in atrioventricular and ventriculoarterial concordance.

Clinical and pathological data of a full-term male newborn with Ebstein's malformation of the mitral valve are reported. Moderate cyanosis and progressive heart failure were present from birth and he died on the fourth day after birth, with clinical evidence of severe aortic coartaction. Necropsy revealed a severely dysplastic mitral valve, with anatomical features of Ebstein's anomaly, in the absence of corrected transposition but associated with aortic coartaction.

[Idiopathic dilatation of the atria: a syndrome? Description of a case of idiopathic biatrial dilatation, review of the literature and a proposal for a pathogenetic interpretation].

Idiopathic severe dilatation of bilateral atrial and urethero-pelvic systems was found in a 53-year-old woman. Degeneration of muscle fibers without inflammation is a constant feature of idiopathic atrial enlargement. Degenerative process can extensively involve atrial wall (generalized dilatation) or can be localized (aneurysmal dilatation). In both types of lesion clinical features are related to atrial arrhythmias and to compression on atrio-ventricular valves and ventricles by the enlarged atria. Only the outcome of the atrial arrhythmias can help to distinguish between the two conditions: development of irreversible atrial standstill in generalized dilatation and definitive restoration of sinus rhythm, following surgery, in aneurysmal dilatation. In each atrium, a different rate of incidence of the two types of dilatation has been documented in the literature: as for the right atrium, more than 40 cases of generalized dilatation have been reported and only 4 of the aneurysmal type. On the other hand, isolated left atrial enlargement was of aneurysmal type in all 30 reported cases. Biatrial dilatation was generalized in 7 cases and due to multiple aneurysms in a single case. The Authors support the hypothesis that idiopathic atrial dilatation could be due to a degenerative process affecting the atrial components derived from primitive atria, in which the muscular layer is structured into pectinate muscles. They also suggest to distinguish, even from the etiopathogenetic point of view, between aneurysmal dilatation (localized and fortuitous lesion) and generalized dilatation (diffuse degeneration of pectinate muscles). This distinction could well related with the different outcome of atrial arrhythmia in the two types of dilatation.(ABSTRACT TRUNCATED AT 250 WORDS)

[The Chernobyl accident. Evaluation of the doses absorbed by the thyroid gland in children of a mountain community from the measurement of I131 retained activity].

I131 thyroid uptake after the Chernobyl's accident was sampled in a Val Pellice school. Children were grouped according to sex, age and area of residence. The procedure used in collecting data and calculating the transformation coefficients from activity counts by computer simulation is analysed, as are the errors and sensitivity of the method. The activities were then converted into doses using an intake model. The dose levels identified are lower than the estimates based on the measurement of environmental matrices. Statistical analysis revealed certain subgroups with significantly different levels of absorption: particularly groups accustomed to a different diet or living in particular areas.
