[Subcutaneous struma recurrence as a sequela of autologous thyreocyte implantation].

Goiter recurrence is a well known fact in the surgical therapy of thyroid diseases. Extremely rare the goiter recurrence is localized in the subcutis or the muscle of the neck. We report on two patients with this type of recurrence. The reason may be an autologous implantation of thyroid follicle cells intraoperatively. It can be avoided by removing all particles of the thyroid gland from the operation area.

[Dust deposits in lung tumors--cause and significance].

In the diagnosis of a so-called scar carcinoma, one of the accepted morphological characteristics is the deposition of dust in tumours of the lung. In 50 bronchial carcinomas in former miners and patients not occupationally exposed to dust, the cause and significance of such lesions were investigated in autopsy and surgical material. Impregnation with dust must be considered to be a secondary phenomenon of the infiltrative tumour growth. Such depositions depend upon previously present dust depositions in the pulmonary parenchyma and on the localisation of the tumour, and reveal a clear correlation with the histological type and degree of differentiation of the tumour.

[Liver stasis in chronic lung and heart diseases].

177 postmortems were analysed where the patients had been suffering from increased right ventricular strain with different underlying diseases. In accordance with the severity of the underlying disease the patients of the lung fibrosis and cardiac defect groups showed a significantly higher percentage of chronic hepatic stasis than those with silicosis and chronic obstructive lung disease. The various degrees of liver congestion allow only limited conclusions in respect of the severity of the underlying disease.

Synchronous carcinoid tumors of the colon--a case report.

Carcinoids are comprising 0.05 to 0.2% of all malignancies and 0.4 to 1% of gastrointestinal neoplasms. Only about 1 to 3% are located in the colon. Because synchronous colonic carcinoids are extremely rare, a case of a 64-year-old woman is presented. Etiologic, clinical and therapeutic aspects are discussed.

[Campylobacter pylori: clinical correlations and prospective comparative studies of various diagnostic techniques].

The diagnostic performance of two different urease tests and of histologic search after modified Giemsa staining to detect Campylobacter pylori (CP) colonization of the upper gastrointestinal tract was prospectively investigated in 215 esophagogastroduodenoscopies, by using a sensitive culture technique as reference. Single antral urease tests had a high specificity of 95-96%, but a limited sensitivity of 78-83%, which increased to 91-94%, when one antral and one additional body biopsy were submitted to the biochemical tests. Giemsa stains were very sensitive, but less specific. The rate of colonization was similar in antrum and body biopsies, and increased with age. There was a close association of Campylobacter pylori colonization with duodenal and to a lower degree with gastric ulcer disease, but especially with gastritic mucosal changes. CP was never detected in patients without gastritis. Therefore, submitting one antral and one body biopsy specimen to validated urease tests represents a sensitive (91-94%) and specific (93%) method to detect Campylobacter pylori colonization, which appears to be a diffuse phenomenon affecting antral and body mucosae with similar frequency.

Campylobacter pylori: prospective analysis of clinical and histological factors associated with colonization of the upper gastrointestinal tract.

The association of Campylobacter pylori (C.p.) colonization of the upper gastrointestinal tract with five predefined anamnestic variables, seven symptoms of dyspepsia, and various blindly evaluated histological criteria, was prospectively investigated in a consecutive series of 149 patients submitted to upper gastrointestinal tract endoscopy. Colonization was determined by biopsy urease tests and histological searches. Significant differences (P less than 0.05) between C.p.-positive and C.p.-negative patients were found for smoker status and the frequency of therapy with ulcer-healing drugs (positive association with C.p.) and antibiotics (negative association), but not for any other of the anamnestic data or symptoms. These data were further submitted to stepwise multiple logistic regression analyses. Concerning histological findings, C.p. colonization was significantly associated with the degree of antrum and body gastritis (P less than 0.01), and also with lymphocellular infiltration in antrum and body biopsies and neutrophil cellular grading in gastric antra. We conclude that C.p. colonization of the upper gastrointestinal tract is associated with gastritic change of the antrum and, albeit to a lesser extent, of the body mucosa. However, a specific pattern of symptoms to predict C.p. colonization could not be established.

[The functionally amputated lung. Studies on the unilateral hyperlucent lung syndrome].

On the basis of comprehensive clinicopathological evidence 6 patients presenting with unilateral left-sided hyperlucent lungs are evaluated for pathogenesis, function and postoperative (n = 5) course. The common denominator in all proves to be moderate to severe hypoperfusion and overinflation of the respective lungs. Pulmonary function is characterized by a combined restrictive-obstructive pattern. In 4 patients overinflation is due to a central check-valve mechanism (tumor: n = 3; central airways collapse: n = 1), whereas in 2 increased translucency results from some sort of peripheral obstruction (Swyer-James syndrome: n = 1; congenital cystic bronchiectasis: n = 1). We consider the origin of hypoperfusion to be alveolar distension and hypoxic precapillary vasoconstriction, both participating in diminished blood flow to the check-valve obstructed lung. In Swyer-James syndrome reduced vascularity is an additional feature. Preoperative and long-term postoperative lung function data of 5 pneumonectomized patients are compared. On the whole, FEV1 and IVC remain unchanged, whereas the obstructive profile (RV, RV/TLC, sRAW) improves. From these data it is concluded that the affected hyperlucent lung is 'amputated' even before operation - irrespective of the nature of tissue damage. On the other hand postoperative relief of airways obstruction is supposed to be due to both antiobstructive medication and the removal of a diseased lung.

Comparison of biopsy urease test and histologic examination for detection of campylobacter pylori in duodenal, antral and fundic biopsies.

The presence of Campylobacter pylori was investigated in duodenal, antral and fundic biopsies of 149 consecutive patients undergoing upper gastrointestinal tract endoscopy by biopsy urease tests (CLOtest; "CLO test") and histologic examination ("HIST") after modified Giemsa staining. Positive results were obtained rarely in the duodenum (4.7% and 12.8% by CLO test and HIST, respectively), but equally frequently in antral (48.3% and 62.4%) and fundic biopsies (55.0% and 54.4%). Using combined evaluations ("COMB") of both CLO test and HIST results, and disregarding isolated positive histologic grades "1" as C. pylori negative, the detection rates were 6.0, 53.0 and 56.4% in the above order and 63.1% overall at any of the biopsy sites. There was no close correlation between the rapidity of the color conversion of the biochemical test and the microscopic grading of C. pylori density. A positive CLO test in single antral biopsy specimens was an accurate predictor of the presence of C. pylori as compared with HIST (predictive value positive PVpos 0.97), while negative antral BUT results did not rule out C. pylori colonization of the upper GI tract (PVneg 0.52 compared with HIST). An additional negative CLO test from fundic biopsies increases the PVneg to 0.58.
