Alterations in circulating thyroid hormones in Indian smokers (bidi and cigarette).

T4, T3 and TSH were estimated in 56 bidi and 50 cigarette smokers and their mean estimates were compared with the corresponding values in 25 healthy non-smokers. T4, T3 and their ratios were significantly lower in both bidi and cigarette smokers (p < 0.001). Circulating TSH in both groups of smokers was similar to that in nonsmokers. T4 and T4/T3 were lower in bidi smokers compared to those in cigarette smokers (p < 0.05 and < 0.01, respectively). Severity of smoking affected T4/T3, and TSH in bidi smokers and T4 in cigarette smokers. Normal TSH excluded any significant decrease in thyroid function in smokers. The alterations in circulating T4 and T3 might have been influenced by thyroid hormone production, protein binding as well as peripheral metabolism of T4 by adverse constituents of bidi/cigarette smoke.

End point for sclerosis of esophageal varices.

BACKGROUND: Small esophageal varices are difficult to inject intravariceally and complete eradication of varices may not be therapeutically necessary. METHODS: A prospective study designed to compare the use of different end points of sclerotherapy ie (i) total eradication (grade 0) (ii) grade I varices or (iii) grade II white (IIw) varices, by stopping variceal injection when one of these was reached. The patients were followed endoscopically and clinically at 3-4 mo intervals. OUTCOME MEASURES: Variceal recurrence and rebleeding rates. RESULTS: Of 266 patients with portal hypertension (147 cirrhosis, 51 non-cirrhotic portal fibrosis, 68 extra-hepatic portal venous obstruction), 232 (87.2%) reached one of the three end points--six to grade 0, 96 to grade I and 130 to grade IIw. Among 212 patients followed up for a mean post-sclerotherapy period of 12.2 mo (range 3-48 mo), variceal recurrence rates, time intervals to recurrence and rebleed rates were comparable in patients with endpoints of grade I and grade II (white) varices (28.5% vs 38.9%, 10.8 mo vs 9.2 mo, and 7.7% vs 7.8%, respectively; all p = ns). Overall, 51 patients had interval bleed before reaching the end point--50 (98%) of them bled from grade III and IV varices while only one patient (2%) bled with grade IIw varices. CONCLUSION: Grade I or grade IIw varices should be acceptable as the end points for endoscopic sclerotherapy of esophageal varices.

Combination of anticholinergic agent and H2 receptor antagonist in duodenal ulcer treatment--a randomized, double blind multicenter study.

BACKGROUND: The acid suppressive abilities of H2 receptor antagonists and anticholinergics have been claimed to be additive. METHODS: A multicenter, double-blind, randomized trial comparing ranitidine (150 mg) plus propantheline bromide 15 mg at bedtime to ranitidine 300 mg alone at bedtime was conducted in 161 patients with endoscopically confirmed uncomplicated duodenal ulcer. RESULTS: After six weeks of therapy, ulcer healing rates in the two groups were comparable ie 80% in the combination group (ranitidine + propantheline) and 79.4% in the ranitidine group. Pain relief after one, two and four weeks of treatment was also comparable in the two groups. Side effects to drugs were minor and comparable in both the groups. CONCLUSION: A combination of 150 mg ranitidine and 15 mg propantheline bromide is as efficacious as 300 mg ranitidine in inducing healing of uncomplicated duodenal ulcers, with similar side-effects but at greatly reduced cost.

[Advanced carcinoma of the thoracic esophagus: CT, MR, and echo-endoscopy in the staging after chemotherapy].

Thirteen patients affected with advanced epidermoid carcinoma of the thoracic esophagus were examined by means of CT, MR and endoscopic US (EUS) before and after chemotherapy. Eleven patients underwent esophagectomy and esophagogastroplasty. An intraesophageal prosthesis was positioned in 2 patients since chemotherapy had not modified tumour stage. Post-chemotherapy CT, MR and EUS parameters were compared with the corresponding pathologic findings. As for MR imaging, post-chemotherapy signal intensity variations in T1 and T2 sequences were also evaluated. MR imaging was more accurate than CT in depicting the involvement of mediastinal fatty layers, the relationships between mass and cardiovascular structures, and the cellularity. CT and MR exhibited limitations in identifying metastatic mediastinal lymph nodes, in which case EUS proved to be the most accurate technique. Both CT and MR failed to satisfactorily assess the infiltration of tracheobronchial tree, which was best demonstrated by endoscopy.

[Inflammation of the anterior chest wall: its assessment by magnetic resonance].

Magnetic resonance (MR) is the imaging method used to assess primary and secondary inflammatory lesions of the chest wall. Five patients with inflammatory lesions of the anterior chest wall were submitted to MR examinations in order to define the role of this method in both identification and assessment of the extent of tissue involvement. In all the examined patients MR Imaging accurately showed the involved muscle groups and the presence/absence of mediastinitis. MR Imaging easily detected sternal and clavicular osteomyelitis; in one patient only MR failed to detect osteomyelitis of the first rib. The accurate assessment of soft tissue infections enabled us to select the most suitable surgical therapy to reduce esthetic damage. Two cases were restudied after chest wall reconstruction by means of rotated pectoral flaps. In the 2 patients in whom the differential diagnosis between inflammatory lesion and recurrent tumor could not be made by means of MR Imaging, CT-guided needle biopsy was performed.
