We report for the first time the simultaneous co-occurrence of these diseases in one patient. A 60-year-old woman was diagnosed with gastric diffuse large B-cell lymphoma （DLBCL） 2.5 years after she was found to have primary mucosa-associated lymphoid tissue （MALT） lymphoma of the breast. Although the patient underwent che-motherapy, she died of leukemia that caused irreversible cytopenia of three lineages. The data show that her MALT lymphoma apparently transfigured into gastric DLBCL. This case highlights the importance of evaluating patients for Helicobacter pylori infection when they present with extranodal MALT lymphomas, except gastric ones. Positive test findings should prompt anti-H, pylori therapy to prevent MALT lymphomas from transforming into DLBCLs.展开更多

Outpatients （536） with psychiatric treatment requiring the dispensing of medication prescribed by a psychiatrist were followed up in a community pharmacy, where different medicines were prescribed as PS （pharmaceutical specialties）, PC （pharmaceutical compounding） or both PS and PC. Each prescription was registered with details on a patient level. Also, three reporting sheets were designed： patients profile, patients monitoring and patients counseling. The total study population in the community pharmacy consisted of 536 outpatients： 357 （66.6%） females and 179 （33.4%） males. Most of the outpatients （78.5%） have health insurance, 50% correspond to public and 28.5% to private institution. The other patients （21.5%） do not have medical insurance. We also observed that the education level of these patients was： primary school 19.1%; high school 45.9%; college 15.3% and university 20.7%. Many patients had more than one psychiatric diagnosis, to whom were prescribed different medicines. All the medication studies on the charts were screened for prescriptions with antidepressants and other psychotropic drugs, starting on the date of first diagnosis made by a psychiatrist. The counseling to the patients was also registered. The possibility of the follow-up of these outpatients in the community pharmacy promoted the development of the psychiatric pharmacy and all advances in care for patients with mental health needs, working in closer collaboration with psychiatrists.展开更多

The purpose of this paper is to briefly review the current state and trend of urban housing in Tehran and search for practical measures to improve the environment and character of urban housing in the city.展开更多
