Numerous studies implicated Helicobacter pylori as one causative agent producing gastritis and dyspepsia. Recent reports focus on another bacterium, Gastrospirillum hominis, as a possible pathogen producing gastritis. We report a 30-year-old researcher who became acutely ill with epigastric pain indicative of esophagitis or peptic ulcer disease. Gastritis and a gastric ulcer were observed endoscopically. Histological examination of the gastric mucosa revealed an acute gastritis and large spiral-shaped organisms. The spiral forms were present in large quantities in the gastric mucosa of experimental animals (cats) handled by the patient in his research. Electron microscopy confirmed that the organisms from the cat and patient were morphologically identical. The patient was successfully treated with bismuth subsalicylate. His symptoms resolved and the organisms were cleared from his stomach. This study provides evidence that another bacterium, a Gastrospirillum, may cause gastritis in man and may be transmitted from animal to man.

The third human case of natural infection by Heterophyopsis continua in Korea was found in Chinju, Kyongsangnam-do. The case was a 53-year-old man. He used to eat raw brackish and fresh water fish. After praziquantel treatment and purgation, H. continua were collected from the diarrheal stool together with Metagonimus yokogawai, Heterophyes nocens and Echinostoma hortense. His clinical complaints were indigestion, epigastric discomfort, poor appetite and fatigue. The complaints were considered rather due to heavy M. yokogawai infection.

A 77-year-old man who had taken ranitidine for several years for dyspepsia was prescribed alternative therapy with famotidine 20 mg twice/day. He subsequently developed mental status changes, with confusion, disorientation, and nightmares. The symptoms dissipated after he discontinued famotidine for 2 days. He rechallenged himself and experienced return of the symptoms shortly thereafter, with additional visual hallucinations. His therapy was changed to lansoprazole, and his symptoms again disappeared and have not recurred. Case reports of central nervous system effects with other histamine2 antagonists have been published. Eight cases occurred with famotidine, all of which were in hospitalized patients receiving intravenous famotidine. We believe this is the first report of mental status changes in an ambulatory patient taking oral famotidine. The elderly may be particularly susceptible to such changes.

Impotence, a common problem especially among older men, can now be treated with Viagra, This oral pill, unlike previous approved treatments mostly involving local injections, does not directly cause penile erection, but increases response to sexual stimulation. It acts by enhancing the relaxant effects of nitric acid on smooth muscle, and thus increases blood flow to certain areas of the penis, leading to erection. It has been evaluated in many randomized trials and in all was more successful in inducing erection than placebos. The most common side-effects include headache, flushing and indigestion, but there have also been reports of fatalities. We describe a 75-year-old man who had an acute myocardial infraction in the past and who had maturity-onset diabetes and hypertension. In the week prior to admission he had a cardiac scan following a few weeks of exacerbation of anginal pain for which he had been taking nitrites. He took a Viagra pill without prescription or medical advice and 2 hours later, during intercourse with his wife, developed audible respiratory distress and lost consciousness. His wife started cardiac massage but not mouth-to-mouth breathing. The emergency team found ventricular fibrillation and gave 5 electrical shocks and amines and atropine. He remained unconscious, but his pulse returned and he was hospitalized. He then had several generalized convulsions treated with i.v. valium. 20 minutes after admission there was asystole and all attempts at resuscitation failed. Cardiovascular status must be considered prior to prescribing Viagra, and the associated risk evaluated.

Rhabdomyolysis is a syndrome provoked by the injury to skeletal muscles and the release of muscle cell contents into the plasma. The aetiology and clinical course are extremely variable. This is sometimes the reason of the diagnostic difficulties or even errors. Acute renal failure is the often and serious complication of rhabdomyolysis. The correct and early diagnosis of rhabdomyolysis is a key to successful treatment and prevention of the possible complications. Two cases of rhabdomyolysis with different aetiology and clinical course are presented in this paper. A 39-year-old man was admitted with the symptoms of dyspepsia. During the first day he developed the acute renal failure and later the acute respiratory failure. The initial serum creatine phosphokinase (CPK) activity was about 225,000 U/L. Haemodialysis, plasmapheresis and respiratory therapy were performed. A 25-year-old man was admitted with the swollen leg of the uncertain origin. His initial CPK activity was 18,993 U/L. The patient was treated with the infusions of fluids and sodium bicarbonate. He did not develop renal failure. Despite of the initial diagnostic doubts, in both cases the outcome was excellent.

Symptomatic oesophageal cancer is usually advanced and the prognosis poor. Lethality of symptomatic oesophageal cancer has motivated screening for these diseases earlier in their evolution, but reliable methods for early diagnosis remain elusive. We have demonstrated that dysregulated expression of minichromosome maintenance (MCM) proteins 2-7 is characteristic of early epithelial carcinogenesis, and that these key DNA replication initiation factors can be used as diagnostic markers for cervical and genito-urinary tract cancer. In this study, we investigated whether minichromosome maintenance protein 5 (Mcm5) can be used to detect oesophageal cancer cells in gastric aspirates. Two monoclonal antibodies raised against His-tagged human Mcm5 were used in a time-resolved immunofluorometric assay to measure Mcm5 levels in cells isolated from gastric aspirates of 40 patients undergoing gastroscopy for suspected or known oesophageal carcinoma or symptoms of dyspepsia. The test discriminated with high specificity and sensitivity between patients with and without oesophageal cancer (85% sensitivity (95% confidence interval (CI)=62-97%), 85% specificity (CI=66-96%)), as demonstrated by the large area under the receiver operating characteristics curve (0.93 (95% CI=0.85-0.99)). Elevated levels of Mcm5 in gastric aspirates are highly predictive of oesophageal cancer. This simple test for oesophageal cancer is readily automated with potential applications in primary diagnosis, surveillance and screening.

Helicobacter pylori (H. pylori) is a "slow" bacterial pathogen, which induces several gastroduodenal diseases. Varying degrees of inflammation can be present in the gastric mucosa of patients infected with H. pylori. The case presented here is a male patient suffering from dyspepsia and nausea. His upper gastrointestinal endoscopy revealed pan gastritis. Histological examination of multiple gastric biopsies taken from the body and antrum showed a rare morphological expression of H. pylori gastritis characterized by diffuse plasma cell infiltration with extensive Russell body formation. Diffuse infiltration of plasma cells with Russell bodies in gastric mucosa can cause difficulties in differentiation from neoplastic processes. However, immunohistochemically, the infiltrating cells in the gastric mucosa stained negatively with cytokeratins while they expressed both kappa and lambda light chains showing their polyclonal nature. The presence of diffuse plasma cells with Russell bodies in the gastric mucosa may represent a different presentation of H. pylori gastritis. There are only two case reports of similar presentation and both have been called "Russell body gastritis".

A 68-year-old man presented to the Emergency Department with a severe metabolic alkalosis after ingesting large quantities of baking soda to treat his dyspepsia. His underlying pulmonary disease and a progressively worsening mental status necessitated intubation for respiratory failure. Laboratory studies revealed a hyponatremic, hypochloremic, hypokalemic metabolic alkalosis. The patient was successfully treated after cessation of the oral bicarbonate, initiation of intravenous hydration, and correction of electrolyte abnormalities.

Giant lipomas of the stomach are very rare, accounting for less than 3% of all benign tumors of the stomach. A clear-cut endoscopic differentiation between gastric lipomas and other submucosal neoplasms is not feasible, because routine endoscopic gastric biopsies do not reach the submucosal layer. Gastric submucosal lipomas can cause gastric ulceration as in the case presented below and in rare instances this may in turn promote gastric cancer. Therefore, complete pretreatment diagnostic evaluation is needed. We present a 52-year-old man with a 6-month history of epigastric discomfort, early satiety, decreased appetite, and dyspepsia. His weight was noted to be stable and he was iron deficient (hemoglobin 11.5 g/dl and ferritin of 5 g/dl). His past history included a gastric ulcer found on endoscopy 5 years ago for which he was on omeprazole 40 mg once a day, hypertension, hypercholesterolemia, and diabetes. Clinical examination revealed central obesity with divarification of recti muscles. He underwent a colonoscopy that was normal, and an oesophago-gastro-duodenoscopy that revealed a smooth extrinsic indentation of the anterior aspect of the distal stomach at around 50 cm. Biopsies of this were normal. A computed tomography scan was obtained () that demonstrated a 14 by 15-cm fatty tumor arising from the distal stomach with a couple of 5-mm nodes adjacent to tumor and no distant metastasis representing either a lipoma, liposarcoma or gastrointestinal stromal tumours. He subsequently underwent a subtotal gastrectomy. Macroscopically, the antrum was distorted by a huge submucosal intramural tumor mass. The antral mucosa was stretched over its surface and bore a central 15-mm ulcer surrounded by a raised border (). Microscopic examination confirmed an ulcerated benign submucosal lipoma. Our patient was symptomatic with a large gastric lipoma that necessitated surgical excision. Following surgery his postoperative recovery was uneventful, and he was asymptomatic when reviewed 4 weeks later. This case demonstrates a rare case of gastric lipoma causing gastric epithelial ulceration leading to iron deficiency.
