Histopathological features of gastritis before and after treatment for Helicobacter pylori.

AIM: To assess five main histological features of gastritis in gastric mucosa colonized with Helicobacter pylori before and after the treatment. METHODS: Histologic assessment of H. pylori-associated gastritis was performed according to the Sydney classification before and after the treatment in 97 patients. Two additional parameters - the presence of lymphocytic aggregates and coccoid forms of bacteria - were also analyzed. Helical and coccoid forms of H. pylori were detected by immunohistochemistry in biopsies after the treatment. RESULTS: Whereas acute epithelial damage was quickly repaired, some of the local responses to bacteria, e.g., lymphoid aggregates and intestinal metaplasia, persisted after treatment. Higher H. pylori and cocci density was found before and after treatment in patients with intestinal metaplasia (p=0.020). Correlation between H. pylori and mucosal atrophy was found only after treatment (p=0.009). Immunohistochemical staining was more sensitive in detecting of H. pylori than Giemsa staining (p=0.007) in cases where, using only Giemsa staining, it was not possible to distinguish coccoid forms of H. pylori from other cocci. CONCLUSION: After treatment, H. pylori-associated gastritis showed reduction of acute and chronic inflammation, but lymphoid aggregates and intestinal metaplasia persisted. Immunohistochemistry of different forms of H. pylori may be a valuable technique in monitoring the success of the treatment.

Autopsy findings and clinical diagnoses: retrospective study of 3,117 autopsies.

AIM: To determine the extent of agreement between clinical and autopsy findings. METHODS: A 14-year retrospective study (1982-1995) of autopsies from the Departments of Internal Medicine and Surgery was performed at the Zagreb University Hospital Center, Croatia. The autopsy findings were compared with the clinical diagnoses. RESULTS: The autopsy rate among hospital deaths ranged between 23% and 33%. The overall rate of major discrepancies was 11.6% for all autopsy reports. The most common cause of death were cardiovascular diseases (40.9%), followed by malignancies (25.2%) and infections (12.9%). Among all cardiovascular diseases, myocardial infarction was the most frequently diagnosed (17.9%) and was misdiagnosed by clinicians in 16.5% of the cases. Incorrectly diagnosed malignancies were found in only 5.7% of the cases; hematological and lymphoid malignancies (48.8%) were the most common neoplasms and were usually confirmed before death. Infections were found in 46.9% of all autopsies. Bacterial pneumonias and peritonitis were overlooked in 67.5% and 23. 5% of the cases, respectively, in which they existed together with another serious condition. CONCLUSIONS: Modern technology has not improved the overall accuracy of clinical diagnoses. When an autopsy should be performed is still a matter of discussion.

Prostatic polyp in the prostatic urethra.

The authors report on a case of prostatic polyp in the urethral bulb of a 35-year-old man. The presence of this lesion in the urethral bulb is quite unusual and may be overlooked on cystocopic evaluation.

Cystosarcoma phyllodes of the prostate.

We report a case of a 40-year-old man with cystosarcoma phyllodes of the prostate. This tumour is very rare in the prostate. The stroma of the tumour was cellular and composed of elongated cells with spindle shaped nuclei, scanty, pale and eosinophilic cytoplasm. Some cells showed nuclear atypia but the cells did not display mitotic activity. We categorised this tumour as benign. The suprapubic prostatectomy was done. The patient is alive and well after three years.

Nucleolar organiser regions and survival in patients with non-Hodgkin's lymphomas classified by the working formulation.

AIMS: To correlate the numbers of silver staining nuclear organiser regions (AgNORs) in non-Hodgkin's lymphoma classified by the working formulation with survival, the first complete remission, and the length of remission. METHODS: Sixty one patients were included in the study. Paraffin wax sections were stained using silver solution to visualise nucleolar organiser regions. The AgNORs were counted in 150 nuclei of each specimen. Data were examined using the Kruskal-Wallis test, multivariate discriminant analysis, and Cox's regression test. Curves were calculated by the method of Kaplan and Meier. RESULTS: Most patients who were alive had low grade lymphoma (p < 0.01). The first complete remission was obtained more frequently in the low and intermediate grade groups (p < 0.05). The longest survival was found in the low grade group (p < 0.001). The mean number of AgNORs differed significantly in all three groups (p < 0.001). This was also true for area of nuclei (p < 0.001) and length of remission (p < 0.05). In a multivariate analysis the numbers of AgNORs were highly predictive for survival, remission, and the length of remission. CONCLUSIONS: The numbers of AgNORs correlated with survival, remission, and the length of remission in patients with non-Hodgkin's lymphoma.

[Primary brain sarcomas].

The authors report on 79 cases of primary brain sarcomas, correlating clinical and pathoanatomical data. In the material analyzed the group of gliosarcomas prevailed, while the smallest group were rhabdomyosarcomas. In some groups the topic predilection did not show any specific characteristics, except that there were more gliosarcomas occurring in the parietal lobe. The symptoms lasted 1-3 months before operation.
