Reducing risk in coronary artery disease. Are Australian patients in general practice achieving targets? The Coronary Artery Disease in general practice study (CADENCE).

BACKGROUND: The benefits of secondary preventive measures for stable coronary artery disease are well established and risk factor treatment targets are defined. AIM: The aim of this study was to examine Australian general practitioners' (GP) perception and management of risk factors in chronic stable angina patients in primary care. METHODS: Using a cluster-stratified design, 2031 consecutive stable angina patients were recruited between October 2006 and March 2007 by 207 GP who documented their risk factors and reported if they were optimally controlled. RESULTS: Among the patients, 93% had objective evidence of coronary artery disease and 63% were male, and mean age was 71 ± 11 years. Based upon national guidelines, recommended targets were achieved in: 60% for blood pressure, 24% for body mass index, 23% for waist circumference, 17% for lipid profiles (low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglycerides) and 54% of diabetics for haemoglobin A1c . However, GP perceived risk factors to be 'optimally controlled' in: 86% for blood pressure (kappa statistic (κ) = 0.37), 44% for weight (κ = 0.3), 70% for lipids (κ = 0.20) and 60% for haemoglobin A1c (κ = 0.74). CONCLUSIONS: In this representative cohort of chronic stable angina patients attending GP, cardiovascular risk factor control was frequently suboptimal despite being perceived as satisfactory by the clinicians. New strategies that raise awareness and address this treatment gap need to be implemented.

Laparoscopic assisted radical vaginal hysterectomy for cervical carcinoma: morbidity and long-term follow-up.

OBJECTIVES: To study the feasibility, morbidity and outcome of cervical cancer patients treated with laparoscopic assisted radical vaginal hysterectomy (LARVH). METHODS: The study group included 53 women with cervical cancer (stage-Ib). They included women undergoing LARVH at the joint cancer-centres between 1994 and 2002. Data was collected on operating-time, nodal-yield, hospital-stay, complications recurrence rate and survival rate. The group was followed up until 2006. RESULTS: Of 53 women who were selected for LARVH, in 2 women LARVH was abandoned when nodes were positive at frozen section. The median age was 42 years while the operating-time was 210 min with a nodal-yield of 23 and a hospital-stay of 5 days. Final histology revealed 10 women with lympho-vascular invasion, 1 nodal metastases and invasion of parametrium/vagina in 2 women. 7 received adjuvant radiotherapy. 3 had chemo-radiation. Complications included voiding difficulty (6), urinary tract infection (5), pyrexia (4), haemorrhage (2), pain (1), port-site haematoma (1) and nerve injury (1). Late complications included lymphoedema (4), urinary incontinence (4), voiding-problems (2), lymphocyst (1), venous-thrombosis (1) and rectocele (1). The median follow-up was 41 months. 4 women had recurrence, of which 3 women died. The five-year survival was 89%. CONCLUSIONS: Vaginal radical hysterectomy with laparoscopic pelvic lymphadenectomy is feasible and safe with regards to mortality and has low morbidity.

2-Arylbenzothiazole as a privileged scaffold in drug discovery.

Substituted 2-arylbenzothiazoles have emerged in recent years as an important pharmacophore in a number of diagnostic and therapeutic settings. Attractive features of drug candidates based on this benzothiazole scaffold include their synthetic accessibility, and synthetic approaches to 2-arylbenzothiazole-based compounds will be reviewed here. Examples of 2-arylbenzothiazoles endowed with diagnostic/therapeutic activity include the 2-(4-aminophenyl)benzothiazole series, which has a remarkable activity profile in both the potential non-invasive diagnosis of Alzheimer's disease and as antitumour agents.

Patterns of glycaemic control in Australian primary care (NEFRON 8).

BACKGROUND: Intensive glycaemic control delays the onset and progression of diabetes-related complications, especially microvascular complications. However, only limited information is available regarding glucose-lowering treatment practices in Australian primary care. The aim of the study was to describe patterns of glycaemic control in subjects participating in the National Evaluation of the Frequency of Renal Impairment co-existing with Non-Insulin Dependent Diabetes Mellitus study. METHODS: Expressions of interest were invited from all registered general practitioners in Australia, from which 500 investigators were randomly selected and asked to provide data on 10-15 consecutive adults with type 2 diabetes presenting to their practice. RESULTS: Just less than half of the 3893 enrolled patients had a haemoglobin (Hb)A(1c) <7.0% (47.7%, 95% confidence interval (CI) 46.1-49.3%) and quarter had an HbA(1c)> or =8.0% (24.3%, 95%CI 22.9-25.9%. For patients using lifestyle alone, one or two oral glucose-lowering agents or insulin there was a progressive decline in the proportion achieving an HbA(1c) <7.0%, that is, 81, 55, 31 and 24%, respectively. There was a very good concordance between general practitioners' perception of optimal control (HbA(1c) <7.0%) and the actual glycaemic levels achieved in this study. CONCLUSION: Current targets for glycaemic control in type 2 diabetes have generally been followed in Australian general practice, but there is still a significant gap in the achievement of recommended glycaemic goals. A quarter of the patients clearly have poor glycaemic control. The immediate steps that can be taken to improve glycaemic control include the early use of combination oral glucose-lowering therapies and the increased use of insulin.

Mullerian adenosarcoma of uterine cervix: report of three cases and review of literature.

BACKGROUND: Mullerian adenosarcoma of the uterine cervix is a rare tumor seen in young women of reproductive age group. It presents as cervical polyps and is a low-grade malignancy with a tendency for local recurrence. Diagnosis can be difficult since it can easily be mistaken for benign polyps, both clinically and pathologically. CASE: We present three cases of adenosarcoma of the cervix presenting as cervical polyps and review the clinical and pathological features of these tumors. CONCLUSION: Adenosarcoma of the cervix should be ruled out especially in women presenting with recurrent cervical polyps. A careful histological examination is mandatory, important prognostic factors being myometrial invasion and sarcomatous overgrowth. Distant metastasis is very rare and therapy can be tailored to suit patient's needs but long term follow-up is essential.

Ovarian malignant melanoma: unusual presentation of a solitary metastasis.

BACKGROUND: Malignant melanomas of the ovary are rare with unpredictable clinical and biological behavior. We present this case report of a metastatic ovarian malignant melanoma, where the ovary was the first site of relapse after 10 years of remission. CASE: A 58-year-old postmenopausal woman was incidentally found to have an abdominal mass, 10 years after removal of a cutaneous malignant melanoma lesion. Ultrasound and CT scan revealed an adnexal mass, which was found to be a solitary ovarian tumor at laparotomy. Histology confirmed malignant melanoma metastasis. CONCLUSION: Relapse after a prolonged period of remission, presenting, as an isolated ovarian metastasis is an unusual presentation of malignant melanoma. As illustrated by this case report, a differential diagnosis of a metastatic malignant melanoma must be considered.

Laparoscopic extraperitoneal paraaortic lymphadenectomy: a study of its applications in gynecological malignancies.

OBJECTIVES: To describe our experience of laparoscopic extraperitoneal paraaortic lymphadenectomy and to study the feasibility, safety and applications of this technique in managing cervical, ovarian and endometrial carcinomas. METHODS: Our study included 32 women with cervical, ovarian or endometrial cancers undergoing laparoscopic extraperitoneal paraaortic lymphadenectomy between December 1997 and May 2002. The operating time, nodal yield, hospital stay and complications were recorded prospectively. The impact on the overall management was assessed by comparing the preoperative therapeutic plan with that following surgicopathological staging. RESULTS: The median nodal yield was 12 nodes, median-operating time was 80 min and the median hospital stay was 2 days. The median follow-up was 15.25 months. Lymphadenectomy was successful in all but one woman who had a peritoneal tear causing CO(2) gas leakage. Complications included one case each of pulmonary embolism, umbilical hernia, lymphocoele, pelvic collection and left-thigh cellulitis. In all women, the need for adjuvant chemotherapy or extended field radiotherapy (EFRT) was based on nodal histology. The primary plan of management was changed in 22.6% women. In the endometrial and cervical cancer group, 8.3% women deferred and 20.8% additionally received EFRT. All women with ovarian cancer (stage I) were completely staged and avoided chemotherapy. CONCLUSIONS: Laparoscopic extraperitoneal paraaortic lymphadenectomy is feasible with minimal complications, acceptable nodal yield and short hospital stay. It accurately identifies those cervical and endometrial cancers requiring extended field irradiation as part of their adjuvant therapy. It can be effectively applied in staging early ovarian cancers to determine the need for adjuvant chemotherapy.

Cytological and histological outcome following a borderline cervical smear.

A prospective cytological and histological study was conducted in 627 women with borderline nuclear abnormality to assess its clinical significance in an attempt to reach a sound policy of management. The incidence of dyskaryosis was 10.9% at a 6-month repeat smear after the first borderline smear. The detection of cervical intraepithelial neoplasia (CIN) after two borderline smears increased to 21.15% on cytology and 40.75% on histology. Additionally, there were two cases of glandular intraepithelial neoplasia and one case of adenocarcinoma detected on histology after having borderline nuclear changes reported on cytology; 39.7% of these women with initial borderline cervical smear were under the age of 30 years. The high prevalence of borderline nuclear abnormality in younger women and a poor correlation between these abnormalities and severity of CIN suggest that repeat cytology is a less than optimal management for these women.

Molecular quantification and mapping of lymph-node micrometastases in cervical cancer.

BACKGROUND: A proportion of patients with cancer and lymph nodes negative on histology will develop recurrence. Reverse-transcriptase PCR (RT-PCR) is a highly sensitive method for detection of lymph-node micrometastases, but accurate quantitative assessment has been difficult. METHODS: We studied primary tumours and 156 lymph nodes from 32 patients with cervical cancer (stage IA2, IB1, and IB2) and 32 lymph nodes from nine patients with benign disease. A fully quantitative, real-time RT-PCR assay was used to document absolute copy numbers of the epithelial marker cytokeratin 19. Primers and probe were designed not to amplify either of the two cytokeratin 19 pseudogenes. FINDINGS: All primary tumours and histologically involved lymph nodes (six) had more than 106 copies of cytokeratin 19 mRNA per microg total RNA. Expression of cytokeratin 19 (up to 1.1 x 10(5) copies per microg RNA) was detected in 66 (44%) of 150 histologically uninvolved lymph nodes, and in nodes from 16 of 32 patients with cervical cancer. 15 of these 16 patients with evidence of micrometastases had the highest cytokeratin 19 transcription level in a first lymph-node drainage station (three obturator, six internal, and six external iliac node). Transcription of cytokeratin 19 was found at a low level in just one of 32 lymph nodes obtained from nine patients with benign disease. Median copy number of cytokeratin 19 transcription was significantly higher (>10(3) copies) in association with adverse prognostic features. INTERPRETATION: The results suggest that about 50% of early-stage cervical cancers shed tumour cells to the pelvic lymph nodes. The amount of cytokeratin 19 expression was related to clinicopathological features. Further studies are required to document the clinical implications of molecular micrometastases.

Applications of the laparoscopic ultrasonic aspirator for advanced gynecologic operative endoscopic procedures.

We evaluated the efficacy of a new laparoscopic ultrasonic aspirator and applied it in gynecologic endoscopy. Two procedures were selected for preliminary evaluation of the instrument; ultrasonic aspiration for selective presacral neurectomies and total laparoscopic hysterectomy (TLH). The aspirator worked successfully in evacuating soft tissue and in adequately exposing the presacral plexus. In TLH we were able to skeletonize the broad ligament adventitia all the way to the level of the uterine arteries bilaterally, including exposure of the ureters. The time required for the procedures varied from case to case, and strongly depended on tissue type and on instruments used to dissect and improve visualization of the operative field. The aspirator may prove useful as an adjunctive in the surgical management of endometriosis, in laparoscopic lymphadenectomy, and in treating complex adhesions after further evaluation is completed.

Bacteriology and antibiotic treatment of perineal suppurative hidradenitis.

A plausible bacterial pathogen (Streptococcus milleri, Staphylococcus aureus, anaerobic streptococcus, or Bacteroides species) was isolated at least once in 26 of 32 patients with active perineal suppurative hidradenitis. The main pathogen was S milleri, whose presence was significantly associated with disease activity and whose disappearance significantly correlated with clinical improvement; S aureus nd anaerobic streptococci were also implicated.

Area variations in infant mortality 1975-7.

Infant mortality rates vary from area to area. Part of this variation is due to the socioeconomic characteristics of the area and part to other factors including the obstetric, paediatric, and community health services. Four social indicators associated with infant deaths are used to control for some of the variations in socioeconomic characteristics and residual variation is then examined. The four social indicators are the level of unemployment, the proportion of large families, the proportion of lone-parent families, and the level of overcrowding.

Treating heartburn in pregnancy: comparison of acid and alkali mixtures.

A randomised crossover trial was performed in 55 pregnant women who complained of heartburn to see whether alkali or acid treatment alleviated it. Each woman was given a week's treatment with an acid mixture, an alkali mixture, and a placebo in randomised order. Both acid and alkali mixtures were better than placebo, but there was no significant difference between the acid and alkali treatments. Together with the inconsistent reports of some patients, these findings suggest that both acid reflux and bile regurgitation may cause heartburn in pregnant women and that other factors may also play a part. Because the cause of heartburn may be difficult to determine, treatment should be empirical. If the patient does not respond to seven days' acid treatment an alkali mixture should be prescribed; there is a 98% chance that one of these treatments will relieve symptoms.

Lumbar epidural analgesia in labour in twin pregnancy.

Fifty twin pregnancies in which the mother received epidural analgesia in labour were compared with 92 in which the mother received standard parenteral analgesia. The duration of the first and second stages of labour; the incidence of assisted deliveries when the head presented; the proportion of breech extractions when either the first or second twin presented by the breech; the incidence of low Apgar scores; and the perinatal mortality were not significantly different in the two groups. These findings suggest that lumbar epidural analgesia is safe for providing pain relief in labour for patients with a twin pregnancy. Moreover, an epidural block is preferable to conventional analgesia in these cases as it allows prompt intervention to effect delivery of the second twin.

Spontaneous premature birth in twin pregnancy.

Factors associated with spontaneous premature birth were investigated in 459 consecutive twin deliveries at this hospital. Low maternal age, low parity, and zygosity were significantly related to the incidence of this complication. The number of previous abortions, sex combinations and related birth order, and mode of presentation of the first twin were not related to the incidence of spontaneous premature delivery. We conclude that apart from low maternal age and low parity there are no obvious factors that would permit early identification of twin pregnancies at risk from spontaneous premature birth.
