Comparison of Cytology and Cervkography in Screening a High Risk Australian Population for Cervical Human Papillomavirus and Cervical intraepithelial Neoplasia

Summary: Two different screening methods, the Papanicolaou (Pap) smear and cervigram were compared in screening 245 Sydney women over a 6-month period in 1988 at a city sexually transmitted diseases (STD) centre, for cervical human papillomavirus (HPV), cervical intraepithelial neoplasia (CIN) and cervical cancer. The Pap smear through the identification of cytologically abnormal cells correctly detected 54% of cases of histologically proven CIN and 39.2% of cases of HPV. The cervigram through the identification of acetowhite epithelium and/or abnormal vessels on the cervix correctly detected 64% of cases of histologically proven CIN and 70.6% of cases of HPV. However, when both tests were used together, 92% of CIN lesions and 82.4% of HPV lesions were correctly identified. Histology of a colposcopically directed biopsy was used as the 'gold standard'. The sensitivity and specificity of the Pap smear after correction for verification bias was 46% and 78% respectively, and for the cervigram was 49% and 60% respectively. Hence neither screening test appears adequate on its own, at least in an STD population.     

Clinical significance of anismus in encopresis

Treatments designed to relieve paradoxical contraction of the anal sphincters during defecation (anismus) have had limited success in children with encopresis. This has raised doubts as to the clinical relevance of this diagnosis in childhood as anorectal dysfunction. Our aim was to determine whether, in patients who had treatment-resistant encopresis, the presence of electromyographic anismus was associated with increased faecal retention. Sixty-eight children with soiling (mean age 8.7 ± 2.06 years) were assessed by clinical examination, abdominal radiography and then with anorectal manometry. Patients with electromyographic anismus (n= 32; 47%) had significantly increased radiographic rectal faecal retention and were significantly less likely to be able to defecate water-filled balloons. There were no significant differences in response to prior therapy, history of primary encopresis, behavioural adjustment or in sociodemographic data. Our results suggest that electromyographic anismus is associated with obstructed defecation and faecal retention.     

Mine Blast Injuries - Our Experience

Background

The sudden increase in incidence and magnitude of mine blast injuries prompted us to highlight the problem and its management.

Methods

The cases of mine blast injuries occurring during mining and demining in a particular geographical area were analysed. Total 27 cases of mine blast injuries occurred during mining or demining operations in a period of 13 months.

Results

Various body regions were involved in the mine blast injuries but the main brunt was borne by feet and legs followed by multiple body regions due to splinters. 14 patients underwent below knee (BK) amputation while 4 patients required through knee (TK) amputations. The effect of blast was so severe that most of the cases required 2 to 5 times wound debridements. The initial aggressive debridement / open stump amputation saved the limb and life of all patients.

Conclusion

A mine blast causes extensive injuries and psychological trauma. Management is needed urgently, surgery is difficult, and amputation is often inevitable. Maximum lives and limbs can be saved with aggressive debridement, repeated inspections and dressings under anaesthesia and definitive closure at optimum time.Key Words: Amputation, Antipersonnel mine, Crush syndrome, Debridements, Mine blast injury, Secondary missiles, Shrapenels     

Prekallikrein-Kallikrein conversion rate as a predictor of contrast material catastrophies

An in vitro is described that attempts to detect patients with a potential for adverse systemic reactions to contrast material. This test involves measuring the rate of conversion of prekallikrein to kallikrein under certain standard conditions. In a preliminary retrospective study, the test could be used to identify such patients with a sensitivity of 88%, a specificity of 82%, and a predictive value of 79%.

Acute Achilles tendon rupture: minimally invasive surgery versus non operative treatment,with immediate full weight bearing. Design of a randomized controlled trial

Background  

We present the design of an open randomized multi-centre study on surgical versus conservative treatment of acute Achilles tendon ruptures. The study is designed to evaluate the effectiveness of conservative treatment in reducing complications when treating acute Achilles tendon rupture.
