NS-21, (+/-)-4-diethylamino-1,1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate, is a new drug for the treatment of urinary frequency and incontinence. To evaluate acute toxicities of its related compounds including the optical isomers of NS-21 ((S)NS-21 and (R)NS-21), the active metabolite of NS-21 ((R/S)RCC-36), the optical isomers of (R/S)RCC-36 ((S)RCC-36 and (R)RCC-36), the hydrolysis products of NS-21 (RCC-32 and RCC-38) and the bi-product of NS-21 (RCC-66), single-dose intraperitoneal toxicity studies were conducted in ddY mice. The LD50 values of these compounds in male and female mice were as follows: 199 and 184 mg/kg for (S)NS-21, 261 and 240 mg/kg for (R)NS-21, 74 and 100-150 mg/kg for (R/S)RCC-36, 93 mg/kg for (S)RCC-36 in both sexes, 83 and 104 mg/kg for (R)RCC-36, higher than 510 mg/kg for RCC-32 in both sexes, 340-510 mg/kg for RCC-38 in both sexes, and 1000-2000 mg/kg for RCC-66 in both sexes, respectively. The clinical signs included decreased spontaneous locomotor activity, prone or lateral position, ataxic gait, clonic convulsion, hypopnea, hypothermia, pale skin, mydriasis, abdominal distention and unkempt fur for (S)NS-21, (R)NS-21, (R/S)RCC-36, (S)RCC-36 and (R)RCC-36, decreased spontaneous locomotor activity, prone position, ataxic gait, clonic convulsion, tail elevation and hypopnea for RCC-32 and RCC-38, and decreased spontaneous locomotor activity and unkempt fur for RCC-66. Body weight was decreased or its gain was suppressed for every compound examined. Pathological examination of the dead mice showed atrophy of the thymus and spleen, intestinal distention with the retention of dark red contents, white spots or white materials in the abdominal fatty tissue for (S)NS-21, (R)NS-21, (R/S)RCC-36, (S)RCC-36, (R)RCC-36 and RCC-66, but no treatment related change for RCC-32 and RCC-38. Adhesion between the abdominal organs was observed in survivors treated with (S)NS-21, (R)NS-21, (S)RCC-36, (R)RCC-36, RCC-32 and RCC-66.

Understanding the distinctions between the management of clinical problems in nursing homes compared with the community setting helps improve the overall care of nursing home residents. Liberalizing diets helps avoid unintentional weight loss in nursing home residents, although the use of feeding tubes usually does not improve nutrition or decrease aspiration risk. Medical assessment, treatment of comorbidities, and appropriate use of rehabilitation therapies minimize the frequency of falls. Toileting programs may be used to treat incontinence and retention in cooperative patients. Adverse effects and drug interactions should be considered when initiating pharmacologic treatment of overactive bladder. Urinary tract infection and pneumonia are the most common bacterial infections in nursing home residents. Signs and symptoms of infection include fever or hypothermia, and functional decline. Virus identification is recommended for influenza-like illnesses. Nonpharmacologic behavioral management strategies are the preferred treatment for dementia-related problem behaviors. The Beers criteria, which outline potentially inappropriate medication use in older persons, provide guidance for medication use in the nursing home.

Melatonin, a major photoperiod-dependent hormone, regulates circadian rhythms and biological rhythms and acts as a prominent sleep promoter. Symptoms related to hypermelatoninemia have been reported in individuals supplemented with melatonin. However, spontaneous endogenous hypermelatoninemia has not been reported previously. A 6-year-old girl previously diagnosed with Shapiro's syndrome was admitted to our hospital on several occasions during a 1-year period with complaints of altered consciousness, syncope, hypothermia and episodes of sweating. The episodes occurred daily and during sleep and lasted for 1-6 h. During these episodes, she sweated profusely and felt faint and her skin was pale and cool. Other complaints included recurrent abdominal pain, urge incontinence and myopia. She was shown to have hypermelatoninemia (>1,000 pg/ml, normal range 0-150 pg/ml) during these episodes. The duration of her attacks decreased with phototherapy and she was successfully treated with propranolol. To our knowledge, this is the first case of hypermelatoninemia without any detectable organic pathology. We did not determine the exact mechanism of hypermelatoninemia in this patient; however, it might have been related to irregular control of pinealocytes by the suprachiasmatic nucleus or related pathways. Hypermelatoninemia should be considered in patients with spontaneous periodic hypothermia and hyperhidrosis, and also in patients with Shapiro's syndrome.

Preservation of continence and sexual function continues to be a formidable quality-of-life issue regarding outcomes after radical prostatectomy. There is little argument that physical preservation of the nerves and sphincters is a critical component to achieving success in these domains. Previously demonstrated factors such as advancing age, deteriorating physical health status, and subnormal baseline potency negatively impact outcomes. Our hypothesis, however, has been that inflammatory response to surgery has a large impact on surgical outcomes of prostatectomy. Trauma-induced inflammation could account for variation in recovery despite nearly identical surgery on many patients, especially in high-volume surgeons. In other words, we suggest and maintain that younger and healthier patients tolerate and/or recover better from the trauma/inflammation of surgery. Those who do not recover as well may have altered inflammatory response to injury. A common response to decrease inflammation in response to physical injury would be as simple as to cool the injury with ice. Previous neurologic studies have suggested that using ice during surgical intervention can reduce the inflammatory damage. Therefore, we applied this concept that preemptive hypothermia could reduce inflammation to the robot-assisted prostatectomy procedure to potentially lead to improved continence and potency outcomes. In 2009, we introduced the concept of regional hypothermia via an endorectal cooling balloon during robot-assisted radical prostatectomy (RARP). We have published our single institution data demonstrating a significant reduction of overall incontinence. Defining continence as zero-pads, our overall 1-year incontinence has been reduced by 70% (from 13% to 4%). Severe incontinence, defined as two or more pads, was likewise reduced by 70% (from 2.9% to 0.9%). Regional hypothermia used during the time of surgery represents a novel strategy for minimizing inflammation and subsequent muscle and nerve damage in RARP.

Lying on the floor for a long time after falling is more common than previously thought among the 'oldest old' and is associated with serious consequences. Older people who are unable to get up off the floor risk complications such as pressure ulcers (often exacerbated by incontinence), carpet burns, dehydration, pneumonia, hypothermia and even death.
