Objective To score the fall risk of hospitalized patients with neurologic disease using fall risk scale and observe the changes of fall risk score after this fall risk scale was used. Methods The fall risk scale in hospitalized patients in neurology department was designed. The fall risk of hospitalized patients in neurology department from January 2005 to December 2007 were assessed. Moreover, safety nursing mea-sures were brought into practice to prevent from falling down. The fall risk of hospitalized patients in neurolo-gy department from January 2002 to December 2004 were assessed too. Results Target patients enhanced the sense of preventing from falling down after the fall risk scale was used, and the incidence of falls in pa-tients was significantly decreased. Conclusions To assess the fall risk of hospitalized patients in neurology department and implement safety nursing measures among the target patients may be effective in preventing the patients from falling down.

Objective:To analyze clinical characteristics of ketosis-associated prurigo pigmentosa after ketogenic diet and bariatric surgery.Methods:Clinical data were collected from patients with ketosis-associated prurigo pigmentosa, who were diagnosed and treated in Department of Dermatology, Peking University People′s Hospital from September 2018 to September 2020. The clinical characteristics, sequelae and therapeutic effect of dietary modification were analyzed and summarized.Results:A total of 6 patients with ketosis-associated prurigo pigmentosa were collected, including 5 females who developed prurigo pigmentosa after ketogenic diet, and 1 male who developed prurigo pigmentosa after bariatric surgery. The skin lesions mainly involved the chest, back, waist and abdomen, and rarely involved the eyelids, axillae, elbows and mons pubis. Common skin lesions included urticaria-like erythema, papules and pigmentation arranged in a reticular distribution, and rare skin lesions included mung bean- to soybean-sized blisters, whose walls were liable to break. Among 5 patients undergoing routine urine analysis, 4 were positive (from + to ++++) for ketone bodies in the urine, and 3 were positive for urinary protein (+) . Pathological examination in 2 patients showed epidermal spongiosis, scattered necrotic keratinocytes, basal cell liquefaction, lymphocyte infiltration in the superficial dermis, and erythrocyte extravasation. The 6 patients were advised to eat staple foods. After dietary modification, 5 patients were nearly cured within 1 week; 1 patient, who continued ketogenic diet for weight loss, still received marked improvement after the treatment with minocycline at a dose of 100 mg/d in spite of restriction of carbohydrate intake. The levels of urinary ketone bodies and urinary protein in the 6 patients all returned to normal within 1 week after treatment.Conclusions:Ketosis plays an important role in the occurrence of prurigo pigmentosa. Dietary modification alone or adjuvant medical treatment such as minocycline is effective for the treatment of ketosis-related prurigo pigmentosa.

Objective To explore the epidemical pattern of acute schistosomiasis in Poyang Lake area so as to provide the scientific evidence for control-strategy-making. Methods The data of acute schistosomiasis in 12 counties along Poyang Lake from 1960 to 2007, including the data of 2 special investigations from 1982 to 1984 and from 1987 to 1989 were collected and analyzed with the retrospective investigation methods. Results There were 29 864 cases of acute schistosomiasis in 12 counties of Poyang Lake area from 1960 to 2007, accounting for 85.5% of the total acute schistosomiasis cases of Jiangxi Province. The largest number of cases existed in Yugan County, accounting for 18. 7%. The peak of acute schistosomiasis prevalence was in 1987 with 2 088 cases. However, the case of acute schistosomiasis declined significantly, keeping at a low level, since 1990. During the 2 special investigations, the people whose age were lower than 30 years old, were the susceptible populations of acute schistosomiasis (86. 1% and 82. 9% , respectively) , most of them were peasants and students, and the infection rates were 57. 4% and 21.2%, 61.7% and 21. 8%, respectively. Fishing and swimming were the main infection ways, with the infection rates of 43.0% and 44.9% , respectively. The peak season of infection was from April to October. Conclusions The river bank and continent of Poyang Lake are the main infection areas, the spring and autumn are the main epidemic seasons and the susceptible populations are the peasants, fishmen and young students. It is very important to enhance the comprehensive prevention and treatment measures in the key areas and population for schistosomiasis control.
