Penetration of antimicrobial agents into the prostate.

In the present review article, the penetration of antimicrobial agents into prostatic fluid and tissue was examined. Three major factors determining the diffusion and concentration of antimicrobial agents in prostatic fluid and tissue are the lipid solubility, dissociation constant (pKa) and protein binding. The normal pH of human prostatic fluid is 6.

Pleural effusion in temporal arteritis.

A 73-year-old woman was admitted to hospital with a one-month history of temporal headache, low-grade fever, fatigue, nocturnal sweats and pleural pain. On the fifth day after admission she developed chest pain at the left site of the thorax, productive cough and progressive dyspnea. A pleural effusion was revealed on physical examination, as well as a bilateral temporal artery thickening.

Brucella melitensis infection stimulates an immune response leading to Kikuchi-Fujimoto disease.

A 43-year-old Greek cattler with a history of brucellosis three months previously for which he was treated with sulfonamides for three weeks, was admitted to the hospital complaining of fever, arthralgias, night sweats, painful cervical and axillary lymph nodes as well as a weight loss of 8 kg in the previous four months. Since microbiological and serological studies did not give a specific diagnosis, an open cervical lymph node biopsy was performed. The histological examination revealed Kikuchi-Fujimoto disease.

The role of N-acetyltransferase-2 and glutathione S-transferase on the risk and aggressiveness of bladder cancer.

N-acetyltransferase-2 (NAT-2) and Glutathione-S-transferase M1 and T1 (GSTM1 and GSTT1) polymorphism have been implicated in the detoxification of urothelial carcinogens, such as arylamines and polycyclic aromatic hydrocarbons. The results of epidemiological studies examining the role of NAT-2, GSTM1 and GSTT1 genotypes on the risk factors for bladder cancer were controversial, although suggesting that there may be an increased risk of the disease associated with these genotypes. The aim of the present study was to examine the independent effect and a possible interaction of NAT-2, GSTM1 and GSTT1 genotypes on the risk of bladder carcinogenesis, in the frame of a case-control study.

Is implant pacemaker a physicochemical cause triggering Kikuchi-Fujimoto disease?

A 64 year-old Caucasian female of Greek origin was admitted to hospital with painful cervical and axillary lymphodenitis accompanied by fever and night sweats for 10 days. The patient had undergone a pacemaker implantation six weeks before disease onset because of heart conduction abnormalities. A diagnosis of Kikuchi-Fujimoto disease was established after lymph node biopsy.
