The Phase 1 semiannual single-dose 6 mg/kg diethylcarbamazine (DEC) treatment program demonstrated a significant reduction for Wuchereria bancrofti in the Ok Tedi area of Western Province, Papua New Guinea. The rate of detectable microfilaraemia was effectively reduced from 39% to 11% and mean microfilarial (mf) densities from 79mf/20 microliters to 19mf/20 microliters. The Phase 2 annual single-dose treatment of 6mg/kg DEC not only maintained the gains made during Phase 1 but reduced the microfilaraemia rate to less than 5% by 1990, with mf densities remaining stable at less than 20mf/20 microliters, amongst all participating villagers screened within the 5 original villages. The annual treatment program was expanded into 7 remote villages not subject to any form of active vector control. The microfilaraemia rate in these villages declined from 41% before treatment to 17% after only two annual administrations of 6mg/kg DEC, and mf blood densities were reduced from 71mf/20 microliters to 20mf/20 microliters. As was observed in the 5 original villages participating in the program, a significant reduction in splenomegaly associated with the DEC treatment was reported for the 7 villages in the expanded program during Phase 2; enlarged spleen rates were reduced from 50% (1986) to 32% (1990) and from 76% (1988) to 48% (1990), respectively. Malaria rates on the other hand increased slightly or remained stable. Malaria infections associated with W. bancrofti (mixed parasite infections) stimulated a greater splenic response than either parasite detected on its own.

OBJECTIVEStudy the actual dosage of clinical prescription in medical department of traditional Chinese medicine (TCM), and offer the consummate data for formulating the dosage standard of Chinese cut crude drug.

METHODWe made use of the methods of stratified sampling and random sampling to investigate 269 882 broth prescriptions of Medical Department of TCM in 21 various hospitals, 18 provinces, and constructed the database, then applied Weka KDD software to analyze.

RESULTWe identified the frequency and clinical dosage intervals of 300 drugs, and the practical dosage of 155 drugs which dose has difference between in the actuality and in the pharmacopoeia. Most of drug's dosage centralized the four intervals: (3-6], (9-12], (12-15], (18-21], and the concrete dosage were 3, 6, 10, 12, 15, 20 g, etc.

CONCLUSIONThe dosages in the pharmacopoeia are not coincided with the practical dosages in internal medicine, and demand to revise. This paper will offer the consummate data for formulating the new dosage standard.

By studying the literatures on the adverse reaction of Yuxingcao injection, the clinical features of ADR were summed up, and the causes of ADR were analyzed through raw material, technology, chemical composition, compatibility and the clinical usage. The causes of ADR induced by Yuxingcao injection are complicated, maybe both due to the medicine itself and the incorrect clinical usage. Multi-measures including manufacture, techniques, clinical usage and some other cases should be taken to prevent the occurrence of adverse reaction of Yuxingcao injection.

OBJECTIVETo investigate possible differences in the prognosis in children with severe nocturia who received different drug withdrawal schedules.

METHODSNinety-seven children with severe nocturia were randomly assigned to two groups: control (n=47) and observed (n=50). The control group accepted drug withdrawal immediately, while the observed group accepted dose tapering gradually after a 12-week treatment course. The frequency of enuresis was observed three months after complete drug withdrawal.

RESULTSDuring the treatment, the frequency of enuresis in all of children from both the control and the observed groups was reduced by over 90%. Forty-six children (92%) from the observed group showed the frequency of enuresis was reduced by over 90%, but 28 children (60%) from the control group (p<0.01) three months after the complete drug withdrawal. There were no significant differences in the adverse effect and the medication compliance between the two groups.

CONCLUSIONSThe different schedules of drug withdrawal may lead to different prognosis, and the schedule of gradual drug withdrawal may be superior to the immediate one in children with nocturnal enuresis.

BACKGROUND: Aminoglycosides are useful for the treatment of aerobic gram-negative infections, and this is despite the narrow therapeutic index and the potential nephrotoxicity and ototoxicity. Once daily dosing of aminoglycosides has recently been suggested as an alternative method to multiple daily dosing. We compared the two dosing regimens of aminoglycosides for the development of nephrotoxicity. METHODS: This study was conducted as part of an ongoing quality improvement program. For the administration of aminoglycosides in adult patients with suspected or documented gram-negative infection, multiple daily dosing was used until April 2005 and thereafter once daily dosing was recommended. RESULTS: A total of 85 patients who received aminoglycoside for more than 3 days from March to August 2005 were available for analysis (40 in the once daily dosing group and 45 in the multiple daily dosing group). The mean duration of administration was 7.7 (range: 3-19) days in the once daily dosing group and 8.0 (range: 3-31) days in the multiple daily dosing group (p=0.83). Aminoglycoside-associated nephrotoxicity was observed in a patient in the once daily dosing group (2.5% vs 0%, respectively, p=0.48). CONCLUSIONS: No significant difference in the development of nephrotoxicity was found between the two dosing regimens for aminoglycosides, but this finding had low statistical power. This may be due to underdosing of aminoglycosides in the multiple daily dosing group.

BACKGROUND: The continuous use of biologic agents in the treatment of psoriasis has been reported to result in successful and sustained therapeutic effects and safety. However, some patients choose intermittent and repetitive treatment. OBJECTIVE: To determine the factors for selecting intermittent and repetitive ustekinumab treatment for the management of psoriasis. METHODS: From January 2011 to October 2016, we enrolled 30 psoriasis patients who discontinued ustekinumab treatment and were followed up for psoriasis treatment. We reviewed data regarding patients' clinical characteristics and the treatment they received, and investigated the factors for selecting intermittent treatment. RESULTS: A total of 52 ustekinumab treatment periods were administered to the 30 patients. Of the 52 treatment periods, 34.6% were covered by insurance and 82.4% were discontinued after sufficient improvement had been made or at the patient's request. Further analysis comparing the first and second ustekinumab treatments revealed that the patients who used ustekinumab in second treatment were more likely to be insured. In addition, the rate of patients reaching psoriasis area and severity index (PASI)75 and PASI90 was similar between the first and subsequent ustekinumab treatments. CONCLUSION: We found that the patients who used ustekinumab intermittently were those who were satisfied with the outcome of ustekinumab treatment but could not afford the treatment. These results suggested that economic burden can be a factor for the patients' choice of short-term intermittent treatment. The expansion of insurance coverage can increase the effectiveness of, and patients' satisfaction with, the management of psoriasis.
