Benign gastric lymphomatosis (gastric pseudolymphoma).

The present paper reports on two cases of gastric lymphomatosis whose diagnosis could only be established by histologic examination of the operative specimen. Benign gastric lymphomatosis (BGL) is characterized by lymphoid infiltration of the gastric wall, predominant in the mucosa and sometimes in the submucosa, running a slow benign course. It must be differentiated from malignant gastric lymphomas and from inflammatory lymphoid reactions surrounding ulcers. BGL have not been treated medically to date. One of the patients initially underwent an eight months treatment with prednisone, then with prednisone and cytostatics, which resulted in clinical improvement but did not modify the pathohistologic picture. As BGL represents a precancerous state and cannot be controlled at present by any medical treatment, the surgical intervention is considered opportune.

Stroke and hypertension. Antihypertensive therapy withdrawal.

The effect of antihypertensive therapy withdrawal in acute ischaemic stroke patients was assessed in order to establish possible correlations between blood pressure values and the modified Rankin Scale (mRS) outcome. One hundred and twelve consecutive patients with acute ischaemic stroke and hypertension were treated with relatively similar regimen. Seventy-two hours following the onset of stroke, systolic blood pressure decreased to < or = 180 mmHg in 110 patients. Antihypertensive therapy was randomly discontinued in 59 patients. Clinical outcome and mortality were compared in patients with and without antihypertensive therapy withdrawal, no statistically significant differences (p > 0.05) between the two groups being found. Statistically significant positive correlations (p < 0.05) between mRS outcome and the decrease of systolic and diastolic blood pressure values were in patients treated with anticoagulant and antihypertensive therapy. Statistically significant negative correlations (p < 0.05) between mRS outcome and low levels of diastolic blood pressure were noted in patients who discontinued antihypertensive therapy. Our findings emphasize the need to associate antihypertensive and anticoagulant therapy in acute ischaemic stroke patients with hypertension. Spontaneous decrease of diastolic blood pressure values showed poor outcome. The management of hypertension associated with acute ischaemic stroke should be reconsidered.

Associated pathology with Wallenberg's syndrome. A report of three cases.

Three cases with Wallenberg's syndrome were reported, in which CT-scan revealed silent old right temporal infarction, right recent cerebellar haematoma and left calcified parietal subdural haematoma evidenced after 10 years since trauma due to a traffic accident. Although Wallenberg's syndrome constitutes a fully clinical diagnosis, CT-scan does not seem to be justified by the management logical deductions of the medical act; however, it is better to perform it in order to identify a possible associated pathology.
