An overview of benign prostatic hyperplasia and its appreciation in Greco-Arab (Unani) system of medicine.

Objective: Conventional treatments for benign prostatic hyperplasia (BPH) like 5alpha-reductase inhibitors and invasive surgery are associated with some obvious side effects. Conversely, evidence, though limited, has shown that alternative medicines are safer and have potential to improve the lower urinary tract symptoms (LUTS) and quality of life in addition to improving sexual dysfunction in patients with BPH. The current article aimed to include an overview of BPH, different ways of its management, and particularly its appreciation in Greco-Arab (Unani) system of medicine, one of the alternative medicinal systems. Methods: PubMed, Scopus, ScienceDirect, Web of Sciences, Google Scholar databases and classical texts of Greco-Arab medicine were searched for data collection. Results: In Unani system of medicine, BPH, traced under the headings of Waram unuq al-mathana (bladder neck swelling) and Insidad majra-i-mathana (bladder outlet obstruction), has been managed for centuries with herbal medicines yet demanding a comprehensive scientific validation. Among the herbs, Cucurbita pepo, Tribulus terrestris, Urtica dioica, and Linum usitatissimum are worth mentioning. Conclusion: For achieving the goal of LUTS-free ageing men, and safer and cost-effective future management of BPH, Unani herbal medicine could hopefully prove beneficial.

Identification and analysis of a novel mutation in PEPD gene in two Kashmiri siblings with prolidase enzyme deficiency.

Prolidase deficiency (PD) is a rare inborn disorder of collagen metabolism characterized by chronic recurrent cutaneous ulceration. We report a novel 3 bp insertion in the 12th exon of the PEPD gene in two Kashmiri siblings with prolidase deficiency phenotype. This mutation results in addition of an extra alanine residue at the amino-acid position number 304 of prolidase peptide. The structural analysis showed that this Ala insertion is located at the helix (a.a. 300-320), which contains several important hydrogen bonds between residues essential for structural folding for the enzyme activity. In silico analysis suggests that this insertion mutation might distort or bend the helical feature to affect the hydrogen-bond network between residues of neighboring secondary structures and deform the metal-binding geometry of the enzyme. Although approximately 70 PEPD gene mutations and polymorphisms have been reported in various ethnic groups, we however report, for the first time, the identification of insertion mutation in human the PEPD gene.
