Followup study on patients with Reiter's disease and reactive arthritis, with special reference to HLA-B27.

An analysis of 160 patients with Reiter's disease, 144 with yersinia arthritis, and 9 with salmonella arthritis was performed, Complete or incomplete Reiter's syndrome was observed in one-third of the patients with yersinia arthritis and in most of those with salmonella arthritis. During the followup period, chronic back pain and joint symptoms were frequent in all the patient groups. Patients who were HLA-B27 positive had a more severe acute disease (more frequent back pain, urologic symptoms, mucocutaneous manifestations, and a longer duration of the disease) and more frequent chronic back pain and sacroiliitis.

Gastric blood flow, tissue gas tension and microvascular changes during hemorrhage-induced stress ulceration in the pig.

Various features of blood supply to the gastric mucosa were studied in the piglet stomach during stress ulceration induced by hemorrhagic shock. Gastric blood flow, as measured by the radioactive microsphere technique, significantly decreased during shock, but no major change occurred in the gastric function of total cardiac output. There was no difference in the magnitude of the decrease of mucosal blood flow between the nonulcerating antral mucosa and the more readily ulcerating corpus or fundic mucosa. At the same time, a significant decrease in tissue partial pressure of oxygen and increase in tissue partial pressure of carbon dioxide occurred, but again no difference was observed between the antrum and the corpus. Microangiographic studies demonstrated a clearly diminished filling of the arterial and capillary bed of the gastric mucosa during shock, suggesting intense vasoconstriction, thrombosis of the mucosal blood vessels, or both. These changes were more prominent in the corpus portion of the stomach than in the antrum. At the site of mucosal lesions, the filling defects persisted even after the shock, suggesting permanent thrombosis of the blood vessels.

Two-picture urography in urinary tract infections.

We analyzed separately from a urographic series 1 radiograph of the kidneys, ureters and bladder after releasing compression. The diagnosis was compared to that of the complete series in 230 consecutive urographic studies performed for recurrent urinary tract infections. The findings were in agreement in 88 per cent of the cases and no therapeutically significant change was overlooked owing to the decrease in the number of exposures. A urographic series with 2 films is described and recommended for the screening of recurrent urinary tract infections in young patients.

Plasma insulin, C-peptide, and blood glucose in portal, hepatic and peripheral veins in liver cirrhosis. Effect of intravenous tolbutamide.

The responses of portal, hepatic and peripheral venous blood glucose (BG), plasma insulin (IRI) and C-peptide (IRC) levels to iv tolbutamide (200 mg) have been determined in 9 non-diabetic patients with liver cirrhosis and in 6 control subjects. The basal levels of plasma IRI and IRC were similar in patients and controls as were the portal and peripheral BG levels. In the hepatic vein, however, the BG-levels were higher in cirrhotic patients than in controls. After tolbutamide administration the BG-levels were unchanged in the cirrhotic patients but a significant fall in hepatic vein BG was observed in controls. In both groups of subjects the highest post-tolbutamide IRI-levels were found in the portal vein whereas the corresponding IRC-levels were as high in the hepatic as in the portal vein. The increments of portal venous IRI and IRC were significantly higher in controls as compared to the cirrhotic patients. Nevertheless, in the peripheral veins the increments of IRI and IRC were very similar in both groups of subjects or even less in the control subjects. The results suggest that in patient with liver cirrhosis the secretion of insulin is not increased but slightly decreased. The production of glucose by the liver also seems to be increased either due to insulin resistance or portal venous shunting of insulin.

Intravenous cholegraphy and ultrasonography in examination of orally nonfilled gallbladders.

The efficacy of intravenous cholegraphy (IVC) and gray-scale ultrasonography (US) in detecting the presence or absence of gallstones was evaluated in 54 patients with orally nonfilled gallbladders. The IVC finding was diagnostic in 26 cases (48%), of which 19 were normal and 7 had gallstones. The respective figures by US were 48 (89%), 18 and 30. In 3 cases only IVC was diagnostic and in 25 cases only US. US was considered to be the method of choice for the secondary examination of an orally nonfilled gallbladder. IVC is justified as a secondary examination if US is not available and is indicated as the tertiary examination if US fails or if a clinical suspicion of gallbladder disease remains after a normal US finding.

Areae gastricae and gastritis in double contrast barium meal.

The areae gastricae were studied in patients with different forms of gastritis and with normal gastric mucosa. The material consisted of 57 patients. First gastroscopy was done and biopsies were taken. The stomach was studied on the following day by the double contrast barium meal. The material was divided according to the gastroscopic and biopsy findings into the following groups: normal, superficial gastritis, mixed gastritis, and atrophic gastritis. In the analysis of the surface pattern, special attention was paid to the shape, size and defects of areae gastricae. Corpus and antrum were dealt with separately. In the normal material the areae gastricae were regular in shape, and the size was usually 1--3 mm. Irregular shape, bigger size and more frequent defect areas seemed to point to gastritis. Such changes were especially clear in atrophic gastritis. The significance of the areae gastricae in practice is discussed.

Localization of occult insulin secreting tumors of the pancreas.

Percutaneous transhepatic portal venography (PTP) and selective portal blood sample collection for immunoreactive insulin (IRI) analyses was done in four patients who had clinical evidence of the presence of an insulin secreting tumor, but selective arteriogrphy of the pancreas did not visualize any insulinomas. In all patients the clinical diagnosis was confirmed and the localization of the tumors could be calculated with the aid of the PTP and the IRI values detected in different parts of the portal trees. Because no tumor was found at the operation in two patients, despite careful exploration of the pancreas, blind distal pancreatectomy was performed to the point suggested with the help of the investigations, and insulinomas were found close to the resection lines. In the two other patients the proposed localization of the tumor preoperatively was confirmed. There have been no postoperative hypoglycemic symptoms.

The value of simethicone in abdominal preparation.

The effectiveness of simethicone in reducing the amount of gastrointestinal gas was investigated with abdominal radiographs in a double-blind study of 169 patients receiving either simethicone or a placebo randomly. There was no statistically significant difference between the two groups. Although simethicone may relieve clinical symptoms and accelerate the transit time of gas, it does not reduce the amount of gas in the gastrointestinal tract. This study indicates that simethicone is not helpful in preparing the patient for radiological examination of the abdomen.

Double contrast examination of the stomach compared with endoscopy.

The results of the double examination of the stomach in a series of 102 patients were compared with the findings at endoscopy. Nasogastric intubation was used to introduce the air into the stomach. Hypotonia was achieved mainly with glucagon. The radiologic error rate was 10 per cent, consisting of 7 per cent false negative and 3 per cent false positive findings. The diagnostic advantages of the double contrast technique over those of the conventional barium examination are discussed.
