Laryngeal carcinoma: sclerotic appearance of the cricoid and arytenoid cartilage--CT-pathologic correlation.

PURPOSE: To assess the significance of sclerotic-appearing cricoid and arytenoid cartilage with computed tomography (CT) in patients with laryngeal carcinoma. MATERIALS AND METHODS: CT scans obtained in 75 patients with laryngeal carcinoma were prospectively studied; laryngeal CT studies obtained in 50 patients without laryngeal carcinoma were retrospectively reviewed. RESULTS: Twenty-four of the 75 patients (32%) with laryngeal carcinoma had sclerotic cartilage. Evaluation of pathologic specimens obtained in 12 of these 24 patients showed 11 cases of sclerotic arytenoid cartilage and two cases of sclerotic cricoid cartilage. Tumor infiltration was demonstrated in six of these cases but not in the seven others. In 11 of the 12 cases with pathologic proof, however, tumor was adjacent to the perichondrium. In the 12 cases without pathologic proof, the proportion was similar. The positive predictive value of this sign for cartilaginous invasion was 46%. CONCLUSION: Although it is not a reliable sign of cartilaginous invasion, sclerotic-appearing cricoid and arytenoid cartilage in patients with laryngeal carcinoma is predictive of the tumor to this cartilage.

Bronchiolitis obliterans organizing pneumonia. An unusual cause of solitary pulmonary nodule.

Bronchiolitis obliterans organizing pneumonia (BOOP) is a pulmonary disorder with a wide spectrum of radiologic features. Usually, these are bilateral, patchy, alveolar, or ground-glass infiltrates, but other presentations have also been described. We present a case in which the radiologic appearance was a cavitated pulmonary solitary nodule. We think that this finding may justify the inclusion of BOOP in the differential diagnosis of the pulmonary solitary nodule.

[Hepatitis B markers at 3 open centers for mentally retarded].

With the aim of investigating the prevalence of hepatitis B virus infection, we studied 161 mentally retarded patients with an age range of 1 to 56, in three open institutions from the Safor Area (Valencia). Some positive serum markers of HBV infection were found in 15 patients (9.3%). The mentally retarded older than 17, presented a prevalence of HBV markers (20.6%), in contrast to those under this age (1.1%) and against the control group (5.1%) (p < 0.001). HBsAg positive markers were found in three cases, representing 4.4% among the older than 17's, against 0.4% of the general population (p < 0.05). There was some positive correlation with personal history of hepatitis (p < 0.01) and severely handicapped patients (p < 0.05) an there was no association with sex, duration of stay and Down's Syndrome. Our results indicate that seropositive B prevalence is similar to the general population in the mentally retarded younger than 17 years old and higher from this age on, which confirms the need for active prophylaxis in the youngest of this collective. Reviewing the Spanish studies we observe a lower prevalence of HBsAg(carriers) and HBV markers in open institutions than in closed institutions.

Neutrophilic pustulosis associated with chronic myeloid leukemia: a special form of Sweet's syndrome. Report of two cases.

Two subjects with Ph-positive chronic myeloid leukemia (CML) in whom pustular Sweet's syndrome was diagnosed are reported. The first patient was a 47-year-old woman who developed fever, painful ulcers of the oral mucosa and vagina and generalized pustulous skin lesions 2 years after the diagnosis of CML. Histologically, the skin lesions consisted of dense neutrophilic infiltrates with perifollicular disposition. The microbiologic studies were negative. The lesions showed a favorable response to corticosteroids, but fever recurred with every attempt of tapering prednisone; it finally disappeared with the addition of oral cyclophosphamide. The second patient was a 45-year-old man who developed fever and disseminated pustules with histologic features consistent with Sweet's syndrome and negative microbiologic studies at 2.5 years after diagnosis of CML. The picture showed a dramatic response to prednisone and did not recur after the drug was discontinued. In both patients, CML remained stable after resolution of Sweet's syndrome.

[Recurrence factors in benign gastric ulcer].

Among 7015 upper gastrointestinal endoscopies done during five consecutive years (1984-1988) 642 patients were diagnosed as having benign gastric ulcer. Of this group, 213 patients have been followed-up during an adequate period of time. A recurrence was diagnosed endoscopically in 43 (20.18%). The authors analyze the influence on recurrences of general factors (age, sex, alcohol, tobacco and drugs), family history and local factors (site and size of the ulcer, histological lesions, concomitant duodenal ulcer or single or multiple ulcers). The conclusions are that in females and in males over 60 years of age, NSAIDS are the factors which greatly influence recurrences, while in males under 60 years of age, excessive smoking and alcohol. Chronic gastritis and intestinal metaplasia are common in recurrent ulcers. Multiple ulcers as well as those associated with duodenal ulcers have a greater tendency to recur. Recurring ulcers are more common at the incisura angularis. Recurrences are usually located at the site of a previous ulcer.

[Barrett esophagus as precancerous lesion].

The incidence of Barrett's esophagus is still little known. Our objective has been to study the incidence of this lesion in our environment as well as the frequency of malignant degeneration in our endoscopic material. Among 12,450 upper digestive endoscopies done in the past 7 years, 945 instances of peptic esophagitis have been diagnosed (7.59%). Among them, 172 cases of endobrachiesophagus (Barrett's esophagus) were detected (1.38% of the entire endoscopy series and 18.2% of all cases of esophagitis). Twenty two of th 172 patients with Barrett's esophagus were diagnosed as having carcinoma (12.79%). Barrett's esophagus is a frequent complication of peptic esophagitis and as the possibilities of malignant changes are as high as 12.79 it should be considered as a precancerous lesion and monitored as such.

[Hepatic activity of glutathione transferase and bromsulphalein metabolism].

The gluthatione transferase activity has been studied in liver biopsies from patients suffering with different hepatic lesion and related to the bromsulphalein (BSP) maximal transport (MT) and the conjugated dye present in serum. Results prove that the MT of BSP is independent of the enzyme activity, but is correlated to the conjugated BSP present in serum during the first perfusion. The enzyme activity, the MT of BSP and BSP conjugated rare in serum are not related to the liver lesion stage. From the analysis of our results we conclude that in the beginning the BSP conjugated proportion is determined by the enzyme activity which is not a restrictive factor of the BSP maximal transport.

Small bowel enema in non-responsive coeliac disease.

A small bowel enema was performed in patients with non-responsive coeliac disease, in coeliac patients on a normal diet (untreated) and those who had shown a good response to a gluten free diet, and in control subjects to determine whether there were any specific radiological features of the non-responsive state. A significant reduction in the average number of jejunal folds and an increase in the number of ileal folds (reversal of the jejunoileal fold pattern) was found in eight of nine non-responsive coeliac patients, one of seven untreated coeliac patients, and in none of the good responders or control subjects. This pattern identifies coeliac patients with a poor response to a gluten free diet who are likely to suffer major complications.

[Multiple familial trichodiscoma].

Trichodiscomas are hamartomas of the pilar apparatus, and have been described alone or associated to other benign proliferations of the pilar complex. Two familial cases of trichodiscomas not associated to pilar alterations or systemic manifestations are described.
