An alternative approach to the surgical correction on malpositions of the uterus]

Endosurgical correction of the uterus was carried out in 57 patients. Indications for surgery were improper positions of the uterus-retroversio, retrodeviatio uteri, excessive mobility of the uterus, and complaints of heaviness at the bottom of the abdomen, leukorrhea, pain of different type in the lower portions of the abdomen, profuse and long menses, dyspareunic pain upon deep penetration, reduced libido, a sensation of a foreign body in the vaginal cleft, urine incontinence upon strain. The mean age of the patients was 35 +/- 3 years. The disease duration varied from 1 to 8-9 years. In 9 women endosurgical correction of the uterus was combined with other interventions on the pelvic organs: colpoperine-orrhaphy with levator plasty was carried out in 5, laparoscopic myomectomy in 2, and dissection of intraperitoneal adhesions in 2 patients. In addition, surgical sterilization was carried out in 54 patients. After surgery the patients were administered only nonnarcotic analgetics. All the patients were discharged on days 2-3, those subjected to combined treatment on days 8-9. The patients were followed up for up to 2 years. The general and psychoemotional status of the majority of patients improved, and the incidence of such symptoms as leukorrhea, pain at the bottom of the abdomen, profuse and long menses was 4, 6, and 5 times reduced, respectively. Endosurgical correction of the uterus in women of a reproductive age should be a method of choice; it can be carried out separately or in combination with plasty of the vaginal walls.     

Increasing the nominal safety of the no. 5 unit of the Kursk nuclear power plant

The main technical measures for increasing the nominal safety of the No. 5 unit of the Kursk nuclear power plant are presented: optimization of the neutron-physical characteristics of the core, adoption of a comprehensive monitoring, control, and protection system, switching to cluster-type control rods, adoption of a system for limiting radioactive emissions during anticipated accidents with pipeline rupture outside the containment system. __________ Translated from Atomnaya énergiya, Vol. 100, No. 4, pp. 320–327, April, 2006.     

An antinociceptive effect of the intraperitoneal injection of nifedipine in rats, measured by tail-flick test

The tail-flick (TF) technique was used to assess the antinociceptive properties of nifedipine (NIF) given intraperitoneally (i.p.). First, the most suitable intensity of the noxious stimulus (temperature of the bulb) has been ascertained and used in the main study. Male Sprague-Dawley rats received NIF, dissolved in dimethyl sulfoxide (DMSO) at the doses of 0.0, 0.5, 2, 5, 10 and 15 mg/kg, or control with no injection. For the main study, the noxious stimulus was limited to 15 sec (cut-off time) and TF latencies were recorded up to 120 min. The antinociceptive response was expressed as the area under the curve for each rat and analyzed by one-way ANOVA. The antinociceptive response to the lower doses of NIF (0.5 and 2 mg/kg) did not differ from control (no injection) and DMSO alone. Significance was found at 5, 10 and 15 mg NIF with no difference among the doses. However, there was an increasing tendency of the mean values from 0.5 to 15 mg NIF resulting in a positive correlation. The correlation coefficient was 0.32483 (p = 0.015) and regression equation Y = (19.37) x dose + 1320. Our data suggest that spinal mechanisms are involved in NIF-induced antinociception.

Experimental-morphological and clinical basis of preventive methods for the intraoperative complications of the amputation of the lower extremity at the thigh level]

Using total quality management principles within a shared governance framework, this case study discusses how to design and implement a plan to achieve independent nursing practice when an employee has unique needs. This experience demonstrates the importance of looking at root causes, separating ability and compliance issues, using all available resources creatively, and planning for success.
