Prostatic Malakoplakia: Case Report and Review of the Literature

A 69-year-old Asian man with a history of overactive bladder presented with postvoid dribbling and urinary incontinence in the past three years. He had cervical spinal stenosis surgery one month ago and two episodes of urinary tract infections with multidrug-resistant Escherichia coli species in urine culture in the last three months. Digital rectal examination revealed a 1-cm hard nontender nodule within the right side of his prostate, concerning for possible prostatic malignancy. Ultrasound study identified a hypoechoic area in the right lateral prostate. Serum prostate-specific antigen level was 2.03 ng/mL (reference range, ≤5.40 ng/mL). Biopsies of the prostate showed only focal chronic inflammation in the left lobe, but there were collections of abundant histiocytes with associated plasma cells and lymphocytes, as well as fibrosis in 5 of 7 cores in the right lobe. Within the histiocytic infiltrate, abundant Michaelis-Gutmann bodies, both intracytoplasmic and extracellular, were identified and confirmed with periodic–acid Schiff and von Kossa stains. The morphologic features and histochemical stains support the diagnosis of malakoplakia. So far, 68 cases of prostatic malakoplakia including ours have been reported (mean age, 63.5 years). Most patients presented with urinary tract symptoms and positive urine culture for E. coli. Eight patients also had associated prostatic adenocarcinoma. Serum prostate-specific antigen may be significantly elevated in patients wi...

Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...

Conclusions: (1) Data at our center suggests at least a regional implementation gap in GBS screening and IAP. (2) The decline in the resistance rate ofE. coli for all antimicrobial substances might indicate that the reduction of prenatal antibiotics use is beneficial and that neonatal antibiotic stewardship programs should include pregnant women as well.What is Known:• GBS screening and intrapartum antibiotic prophylaxis led to a 32%-reduction in GBS disease in Germany with a 0.75 (92:122) ratio of early-onset disease to late-onset disease in 2009–2010.• Prenatal antibiotic use might increase the risk of E....

Conclusion: Ambulatory renal and cardio-vascular follow-up in case of neonatal medical history can be enhanced, with necessity to raise awareness and to edict guidelines available to pediatricians.What is Known:•There is a compelling evidence of long-term renal and cardiovascular consequences of prematurity and low birth weight.•Specific cardiovascular and renal follow-up guidelines, coming from professional organizations, are currently not available for these patients.What is New:•Pediatricians in ambulatory setting do not adapt their renal and cardiovascular follow-up in case of neonatal medical history.&b...

CONCLUSION: The ultrasonography measure of right liver lobe diameter by itself can reliably identify patients with NAFLD with a good sensitivity and specificity, however, this can be improved by adding the LAP mathematical index in our population. PMID: 33031969 [PubMed - as supplied by publisher]

This study was designed to examine the effect of TEAS for pain relief in women undergoing transvaginal ultrasound-guided oocyte aspiration. This single-blinded, multicenter, randomized controlled trial was performed in China between May 2013 and May 2015. The subjects were randomized to mock TEAS and TEAS. TEAS or mock TEAS was administered 30 min before oocyte retrieval until the end of the operation. The primary and secondary endpoints were the pain measured using the visual analog scale (VAS) within 1 min and 1 hour after oocyte retrieval, respectively. Serum β-endorphin levels were tested in the firs...

This study investigated antibacterial-producing Streptomyces isolated from the gut of estuarine fish Chanos chanos, emphasizing screening for the producer of peptide-containing antibacterial compounds. Eighteen isolates were found during preliminary screening, in which four isolates showed the best antibacterial activities. Based on the morphological, physiological, and biochemical characterization, as well as 16S rRNA partial sequencing, all of the four isolates belonged to Streptomyces. Three isolates were suspected as novel isolate candidates based on homology presentations and phylogenetic tree analysis. Disk-diffusion...
