Primary non-Hodgkin's lymphoma of the liver is an extremely rare lymphoma subset that often presents with diagnostic difficulties to both clinicians and pathologists. Using MEDLINE search, 90 cases of primary hepatic lymphomas reported in the literature were reviewed. The epidemiology and etiology, clinical presentation, pathologic features, management, and outcome of these patients have been summarized and described. Results of this review show that middle-aged males are most often affected. Abdominal pain or discomfort, weight loss and fever are the most frequent presenting symptoms. Most cases have a solitary or multiple mass lesions in the liver, and are frequently misdiagnosed as having a primary liver tumor or metastatic cancer. Diffuse large cell lymphoma is the most commonly encountered histologic subtype. Surgery, chemotherapy and radiotherapy have been used alone or in combination as treatment but the outcome is generally poor. Although primary hepatic lymphoma is an aggressive disease, it is resectable, and responsive to chemotherapy and radiotherapy. Because of the profound therapeutic implications, it should be considered in the differential diagnosis for patients presenting with mass lesions in the liver or hepatic disease.

Irritable bowel syndrome (IBS) represents one of the most common gastrointestinal-related diagnoses. Although the precise etiologic basis of IBS is not known, a common presenting symptom is abdominal pain or discomfort that is thought to develop, at least in part, from a heightened awareness of visceral nociceptive input. Agents capable of reducing this heightened visceral nociception would, therefore, have utility in the treatment of IBS. In this study we evaluated the effects of intravenous and intracerebroventricular administration of a 5-HT3 receptor antagonist, alosetron, on blood pressure changes associated with rectal distension in anesthetized and awake dogs. This vasoactive reflex serves as a model for visceral nociception. For intracerebroventricular studies, the cerebroventricular guides were placed over the lateral ventricle. In anesthetized studies, blood pressure was measured by femoral artery cannulation. In awake studies, blood pressure was monitored by noninvasive measurement. A rectal balloon was placed in the rectum of each dog and maintained throughout the experiments. Each dose of alosetron was given to the dogs as an intravenous or intracerebroventricular bolus, and every 30 min the rectal balloon was inflated and blood pressure responses observed. In both anesthetized and awake dogs alosetron produced a significant inhibition of the vasoactive reflex. In particular, alosetron showed high potency when administered intracerebroventricularly. Alosetron, administered either centrally or peripherally, appears to modulate the visceral nociceptive effect of rectal distension in dogs.

Boerhaave's syndrome (spontaneous esophageal perforation) is an uncommon clinical entity that frequently presents with an antecedent history of marked vomiting followed by chest or abdominal pain. We report a case of spontaneous rupture of the esophagus in 53-year-old male who was referred to our hospital with a chest discomfort. A chest radiogram revealed pleural effusion and pneumomediastinum. Nine hours after onset, the diagnosis of Boerhaave's syndrome become evident. She underwent operative repair and, after a prolonged stay, was discharged in relatively good condition 55 days after admission. The absence of vomiting prior to presentation is the distinguishing feature of this particular case. This is the seventh case in the English literature to our knowledge.

The efficacy and safety of minocycline was investigated in Japanese patients with rheumatoid arthritis (RA) who had already received more than three disease modifying anti-rheumatic drugs (DMARDs). Minocycline was administered at 100 mg twice a day to fifteen patients with active RA. The drug efficacy was evaluated by the clinical variables including the number of painful and/or swollen joints, the duration of morning stiffness, grip strength, the erythrocyte sedimentation rate, serum concentrations of C-reactive protein, and the titer of rheumatoid factor. Three patients experienced adverse effects such as dizziness and abdominal pain or discomfort, but only one patient with abdominal pain and dizziness was discontinued. Fourteen RA patients, who had taken minocycline for at least 6 months, were subjected to the clinical evaluation. Among them, 8 patients (54%) showed a significant improvement of clinical valuables for disease activity, beginning even at 4 weeks of the therapy. The continued effects were observed in 8 patients with over 1 year-minocycline therapy. Intriguingly, an active patient with a history of multiple DMARDs-resistancy showed a marked favorable response to this drug. The present study indicates that minocycline may be an effective DMARD with highly safe performance for patients with active and refractory RA. This is the first demonstration of the benefit of minocycline in the Japanese patients.

Our objective was to determine if local anesthesia reduces pain after a laparoscopy. Eighty women were assigned randomly 10 ml of 0.5% bupivacaine or 0.9% saline flushed over the peritoneal folds and into the abdominal wall after laparoscopy under general anesthesia. Pain scores from the deep abdomen, skin, shoulder, and back were collected 30 min, 2 h, 4 h, and the day following laparoscopy. Pain scores also were correlated with patients' height, weight, operative findings, surgical technique and procedure, and volume of gas insufflated into the abdomen. Bupivacaine has a small effect on abdominal and skin pain 2 h after surgery (p = 0.01) but has no effect on shoulder or back discomfort. Women who have been sterilized, have not had previous abdominal surgery, or have evidence of old pelvic inflammation report more postoperative backache and deep abdominal pain but no greater skin or shoulder discomfort. Weight, height, whether the abdominal wall was picked up, and the volume of gas used to insufflate the abdomen are independent of all postoperative pain scores. Local anaesthetic instilled down the laparoscopy trocar reduces skin discomfort 2 h after surgery, but this beneficial effect is small compared with other factors influencing pain after laparoscopy.

We describe a rare case of a celiomesenteric anomaly with concurrent aneurysm. The patient, a 53-year-old man, had no abdominal pain or discomfort. The presence of a celiac artery aneurysm was suspected on the basis of the results of abdominal computerized tomographic scanning and echo ultrasound scanning performed because of proteinuria. Intra-arterial digital subtraction angiographic results showed the anomaly and aneurysm. Because of the risk of rupture of the aneurysm, the lesion was repaired surgically, with the placement of an interpositional prosthetic graft. We found no previous reports of celiomesenteric anomaly with concurrent aneurysm repaired with prosthetic graft.

Degos' disease is a rare multisystem vasculopathy of unknown etiology. We report a 44-year-old man who presented himself with gait and sensory disturbances mainly due to thoracic transverse myelopathy four years after the appearance of many characteristic umbilicated papules over the trunk and extremities. He did not complain of abdominal pain or discomfort. Laboratory, electrophysiological and imaging studies did not show any characteristic change, except for the increase of protein contents and cell counts in the cerebrospinal fluid. We tried methylprednisolone pulse-dose therapy (1,000 mg/day x 3 days) five times, but this patient's neurological condition worsened stepwise after it, although the appearance of new skin lesion was suppressed. Intravenous infusion of ozagrel sodium and cyclophosphamide (1,000 mg/day) were also ineffective, and this patient died of respiratory failure after showing oculomotor paresis and comatose state. Necropsy revealed Degos' disease-specific vasculopathy in the central nervous system and the gastrointestinal tract, where occlusions of small-sized arteries and veins due to the intimal thickening were evident. The tissue necrosis was macroscopically remarkable in the brainstem and the thoracic spinal cord. The efficacy of steroid therapy for this disease should be investigated more carefully.

We report a case of symptomatic intermittent upper tract obstruction in a continent urinary reservoir. The ureters were of great intraperitoneal length and were positioned in front of the mesenterium, resulting in a mobile reservoir. Only the retroperitoneal part of the ureters was dilated due to kinking in the peritoneal passage. After the ureters were shortened and reanastomosed retroperitoneally, the repeated episodes of abdominal pain and discomfort disappeared..

Distension of the gastrointestinal tract elicits abdominal pain, as well as sensations such as discomfort or fullness. Many patients with irritable bowel syndrome have been reported to show a reduced threshold to the pain or discomfort due to experimental rectal distension. This hypersensitivity of the gut may be characteristics of the irritable bowel, as well as other functional gastrointestinal disorders. Intestinal distension in animals induces a range of responses which have been used as indexes of visceral nociception. This paper reviews a recently introduced canine model used to assess the antinociceptive properties of a novel 5-HT3 receptor antagonist, alosetron.

The meaning and definition of dyspepsia continues to challenge clinical investigators and has led to the setting up of several international working teams. However, confusion continues to reign around this term. The effort to classify patients with dyspepsia into subgroups according to their most predominant symptoms has failed to provide clues to the underlying disease, or even to discriminate between functional and organic dyspepsia. With these limitations in mind, the question arises: is there any reason for putting further effort into developing a world-wide definition of dyspepsia when, in addition to the aforementioned shortcomings, further variables such as geographical region, ethnic background, culture and sanitary resources come into play? The answer is that only by establishing a reproducible methodology for individual symptom assessment using a well-defined protocol will comparisons of the prevalence of dyspepsia and the impact of different therapeutic interventions become possible around the world. The data on dyspepsia prevalence, nearly all arising from studies in a few developed geographical areas and countries, are of the order of 1-4% of all consultations in all primary care medicine. However, estimates of adults affected by dyspepsia are as high as 20-40%. The magnitude of these statistics underlines the necessity for further work on the concept of dyspepsia and its major functional subgroups, following the exclusion of any organic causes. Issues such as 'investigate dyspepsia before starting with any kind of treatment or treat dyspepsia before further investigation' or the debate about whether to 'eradicate or ignore Helicobacter pylori in functional dyspepsia' will remain unresolved unless studies performed throughout the world use widely comparable and acceptable definitions and criteria for these conditions. Since the first international working party report in 1988, definitions of dyspepsia have included the description of 'upper abdominal pain or discomfort' and, more recently, have specified 'pain or discomfort centered in the upper abdomen' in order to emphasise further the site of origin as the upper alimentary tract (stomach-duodenum). However, a major change was evident in the more recent Rome I and Rome II reports, in which the symptoms heartburn, acid regurgitation, and belching were excluded from the definition of dyspepsia because of their relation to gastroesophageal reflux disease (GERD) and aerophagia. The intention to define a set of symptoms for dyspepsia is good, but we continue to be faced with overlaps. How should the patient with epigastric pain and heartburn after endoscopic exclusion of duodenal ulcer and reflux esophagitis be classified: dyspepsia or GERD? In cases of abnormal gastroesophageal reflux, 24-h pH monitoring could help to resolve this dilemma, but what if this investigation turns out to be normal? In this field, we need to perform careful studies. In addition, we need to consider the lifestyle and cultural habits of people around the world when translating upper gastrointestinal symptoms into dyspepsia. A step forward in the definition of dyspepsia was attempted by the recent working party for the Rome II consensus on functional gastrointestinal disorders (N. Talley et al.). In this project, the symptoms of dyspepsia were individually described not by a single term, but by painting a 'word picture', to make it easier for patients to express their symptoms, and give doctors and clinical investigators a better understanding of the 'dyspeptic problem' of each individual. It is advisable to follow this approach, since a clear picture of a patient's symptoms, including their duration and intensity, in association with the modern technical approaches that allow investigation beyond organic causes of dyspepsia, will lead to progress in our understanding and better communication about this problem within the medical community, and ultimately to better treatment.
