2.Drug therapy of overactive bladder - What is coming next?.
Korean Journal of Urology 2015;56(10):673-679
After the approval and introduction of mirabegron, tadalafil, and botulinum toxin A for treatment of lower urinary tract symptoms/overactive bladder, focus of interest has been on their place in therapy versus the previous gold standard, antimuscarinics. However, since these agents also have limitations there has been increasing interest in what is coming next - what is in the pipeline? Despite progress in our knowledge of different factors involved in both peripheral and central modulation of lower urinary tract dysfunction, there are few innovations in the pipe-line. Most developments concern modifications of existing principles (antimuscarinics, beta3-receptor agonists, botulinum toxin A). However, there are several new and old targets/drugs of potential interest for further development, such as the purinergic and cannabinoid systems and the different members of the transient receptor potential channel family. However, even if there seems to be good rationale for further development of these principles, further exploration of their involvement in lower urinary tract function/dysfunction is necessary.

Malakoplakia is a rare granulomatous disease that occurs commonly in the urinary tract and secondarily in the gastrointestinal tract. Most reported cases of malakoplakia are associated with immunosuppressive diseases or chronic prolonged illness. Here, we report a rare case of malakoplakia in a young healthy adolescent without any underlying disease. A 19-year-old female was referred to our hospital following the discovery of multiple rectal polyps with sigmoidoscopy. She had no specific past medical history but complained of recurrent abdominal pain and diarrhea for 3 months. A colonoscopy revealed diverse mucosal lesions including plaques, polyps, nodules, and mass-like lesions. Histological examination revealed a sheet of histiocytes with pathognomonic Michaelis-Gutmann bodies. We treated the patient with ciprofloxacin, the cholinergic agonist bethanechol, and a multivitamin for 6 months. A follow-up colonoscopy revealed that her condition was resolved with this course of treatment.

Corticosteroids are used in the treatment of many diseases; however, they also induce various side effects. Dexamethasone is one of the most potent corticosteroids, and it has been reported to induce the side effect of impaired salivary gland function. This study aimed to evaluate the effects of dexamethasone on mouse submandibular gland function to gain insight into the mechanism of dexamethasone-induced salivary hypofunction. The muscarinic agonist carbachol (CCh) induced salivary secretion and was not affected by short-term dexamethasone treatment but was decreased following long-term dexamethasone administration. The expression levels of the membrane proteins Na-K-2Cl cotransporter, transmembrane member 16A, and aquaporin 5 were comparable between the control and long-term dexamethasone treatment groups. The CCh-induced increase in calcium concentration was significantly lower in the presence of extracellular Ca in the long-term dexamethasone treatment group compared to that in the control group. Furthermore, CCh-induced salivation in the absence of extracellular Ca and Ca ionophore A23187-induced salivation was comparable between the control and long-term dexamethasone treatment groups. Moreover, salivation induced by the Ca-ATPase inhibitor thapsigargin was diminished in the long-term dexamethasone treatment group. In summary, these results demonstrate that short-term dexamethasone treatment did not impair salivary gland function, whereas long-term dexamethasone treatment diminished store-operated Ca entry, resulting in hyposalivation in mouse submandibular glands.
