We report a rare case of esophageal intramural pseudodiverticulosis with lower esophageal stricture which perforated into the peritoneal cavity after the patient vomited. A 61-year-old man was admitted with severe chest and epigastric pain after dysphagia and vomiting. Under a diagnosis of upper gastrointestinal perforation, laparotomy was performed. ⋯ Histological examination revealed esophageal intramural pseudodiverticulosis with esophageal stricture distal to the site of rupture, and postoperative endoscopy showed diffuse pseudodiverticulosis in the remaining esophagus. The patient is free of symptoms 5 years after the surgery. This case suggests that careful treatment may be indicated in patients with esophageal intramural pseudodiverticulosis with stricture and elevated intraluminal pressure, to minimize the possibility of severe complications such as esophageal perforation.

Review Case Reports
Non-traumatic gas gangrene in the abdomen: report of six autopsy cases.
Six autopsy cases of non-traumatic gas gangrene in the abdomen are reported. Five of the six were caused by clostridia, as identified by culture or histology. There were associated underlying diseases, such as alcoholism, liver cirrhosis, diabetes mellitus, and malignant disease. ⋯ None of the six patients was clinically diagnosed as having gas gangrene. We suggest that gas gangrene should be considered in any patient with abdominal infection. A review of 19 autopsy cases of gas gangrene in the abdomen reported in the Japanese literature is also presented.

Review Case Reports
A patient with primary biliary cirrhosis associated with autoimmune hemolytic anemia.
Primary biliary cirrhosis is often associated with autoimmune conditions, such as thyroid disease, sicca complex, and rheumatoid arthritis. However, an association with autoimmune hemolytic anemia has rarely been reported. We present a case of primary biliary cirrhosis associated with warm type autoimmune hemolytic anemia, and we review prior reports.

Comparative Study
Use of salivary acetaminophen concentration to assess gastric emptying rate of liquids.
The gastric emptying rate (GER) of liquids can be quantified by calculating the rate of acetaminophen absorption from serial plasma concentrations. As acetaminophen concentrations in saliva are well correlated with those in plasma, the salivary concentrations may be suitable for use in GER measurement. To evaluate such suitability, salivary and plasma samples were simultaneously obtained from seven healthy volunteers at 0, 0.25, 0.5, 0.75, 1.0, 1.5, and 2.0 h after they had ingested 20 mg/kg of acetaminophen mixed with a 200-ml liquid meal (200 kcal). ⋯ Significant correlations between saliva and plasma were found in all parameters studied (r = 0.77-0.90; P < 0.05). However, except for t(max), the salivary parameters overestimated those of plasma. The present results suggest that: (1) the salivary acetaminophen concentration at 0.25 h (C0.25) is a poor reflection of plasma C0.25 (2) thereby the parameters embodying salivary C0.25 such as AUC1.0 and the AUC0.5/AUC2.0 ratio, are unreliable, and (3) liquid GER can be assessed by salivary t(max) with minimal distress to the patient.
