Scholarly productivity: are nurse academics catching up?

The aim of this study was to document the amount of recent change in Australian nurse academics' scholarly productivity and to investigate the influence of demographic factors such as gender, academic rank, qualifications, increase in qualifications, state of residence, university and university size. Scholarly productivity was calculated from an audit of journal articles. The findings of this study indicate that, while there has been a slight increase in scholarly productivity in the last five years, nursing still lags behind other disciplines. Scholarly productivity was found to be positively associated with highest academic qualification, academic rank and promotion. The study indicates the continuing need for senior nurse academics to provide mentoring to colleagues and foster the development of skills associated with scholarly productivity.     

Primary tuberculous nasal polypi—A case report

Primary tuberculous pathology in nasolpolypi is a rare condition. A case of bilateral ethmoidal polypi with tubercular lesion diagnosed on histopathologlcal examination is being reported and the available relevant literature has been reviewed.     

Pelvic Pain Complicating LHRH Analogue Treatment of Fibroids

We present these 3 cases to alert others to the possibility of severe pain with rapid shrinkage of fibroids occurring during LHRH analogue treatment. We suggest management of such events should not be surgical except for vaginal excision of prolapsed fibroid polyps.     

Voltage-gated Currents in Rabbit Retinal Astrocytes

The voltage-gated currents of the astrocytes associated with the retinal capillaries of the rabbit retina were studied using whole-cell patch clamp recording. The resting potential of these cells was −70 ± 4.8 mV (mean ± SEM; n = 54), and the input resistance and cell capacitance were 558 ± 3.6 MΩ and 19.5 ± 1.8 pF respectively. Depolarization to potentials positive to −50 mV evoked rapidly activating inward and outward currents. The inward current was transient, eliminated by substitution of choline for Na⁺ in the bathing solution, and reduced by 50% in the presence of 1 μM tetrodotoxin. The time-to-peak of the Na⁺ current was more than twice that for the Na⁺ current found in retinal neurons. The glial Na⁺ current was half-inactivated at −55 mV. A transient component of the outward K⁺ current was blocked by external 4-aminopyridine while a more sustained component was blocked by external tetraethylammonium. At potentials between −150 and −50 mV the membrane behaved Ohmically. Voltage-gated currents in retinal astrocytes recorded in situ appear qualitatively similar to those described for some glial cells in vitro.     

糖化血清蛋白测定对糖尿病监控临床意义的探讨

目的：对临床确诊糖尿病患同时测定血清葡萄糖(Glu)及糖化血清蛋白(GSP)的含量，观察二的关系，以及糖化血清蛋白水平对于评价近期(2—3周)糖尿病患血糖在体内变化的临床意义进行了观察。方法：血清葡萄糖、糖化血清蛋白测定均采用酶法测定。结果：178例糖尿病患Glu、GSP均正常3l例占17．4％；Glu、GSP均增高107例占60．1％；Glu正常、GSP增高15例占8．43％；Glu增高、GSP正常25例占14％。结论：糖化血清蛋白的含量不受即时血糖的影响，二的变化不成比例性，对评价糖尿病患2～3周病情的控制是一项灵敏可靠的指标，尤其对于住院病人的治疗与监控有一定的意义。     

FUSION OF THE FIRST METACARPOPHALANGEAL JOINT FOR POST-TRAUMATIC CONDITIONS

Fusion of the metarcarpophalangeal joint of the thumb is an accepted treatment in the management of instability or osteoarthritis following trauma to this joint. A review was made of the literature and 30 of the senior author's (RH) patients who had had this operation, in order to determine what effect the operation had on the pain in their thumb, any symptoms of instability, interference with work and daily activities, and strength in the hand. All of the patients achieved bony union and the average angle of fusion was 7.6 degrees of flexion. All of the patients were either satisfied or very satisfied with the results of the operation, and had an average increase of 6.3 points on a 12 point rating scale. However, 48% of patients had some mild intermittent pain and 43% complained of some difficulty with fine motor tasks. Twelve patients were able to attend for formal evaluation including the Jebson and Crawford Hand Function Tests which revealed some decrease in hand function in all of those tested. It was concluded that this method of arthrodesis of the metacarpophalangeal joint of the thumb gives reliable results, with high patient acceptance, but does not result in an entirely normal thumb or hand function.
