Abstract
Abstract
The concepts of adaptive management and participatory forest management (PFM) reflect an increasingly holistic relationship between society and its forests. Adaptiveness depends on learning processes. This review considers the ways in which PFM has been assessed in recent literature and focuses on the role of learning, through cross-cutting quantitative analyses, project monitoring and evaluation, and participatory research and experimentation. Such literature highlights the importance of policy, and the gap between legislation and implementation; social and institutional arrangements; appropriate silviculture and monitoring, and the participatory methods needed to develop it. Much of this is analysed at the local or national scale, but emerging discourses on forest governance highlight the need for partnership, organizational learning, and adaptiveness across a range of spatial scales and cultural perspectives. The review concludes that the common factors in adaptive PFM are context specificity, tenure and institutional security, reliable and relevant information, and learning processes, leading to adaptive technology, institutions and organisations, underpinned by close attention to ecology. This is summarized in an analysis proposing a broad evolutionary pattern from 'first generation' attention to structural factors such as tenure and formal roles and relationships, through 'second generation' concerns emerging from experience of diversity and inequity, to a more qualitative, actor-centred approach to learning and adaptation. The big challenges for PFM are adaptive technology, requiring participatory research in silviculture, sustainable harvesting and monitoring; and adaptive organizations and institutions.

Abstract
Mixed connective tissue disease (MCTD) has been rarely reported from India. Thus, we did a retrospective analysis of cases of MCTD seen at our hospital during the last 13 years. We found 16 cases among 441 patients with connective tissue disease. All the 16 patients (15 females) of MCTD fulfilled classification criteria by Kasukawa and at least one of the other two (Sharp's and Alarcon-Sergovia). Raynaud's phenomenon, sclerodactyly, puffy fingers, esophageal hypomotility, and pulmonary disease were the most common manifestations. At a median follow-up of 12 months (1-172), 12 patients developed features of limited scleroderma and three patients had pulmonary hypertension.

Abstract
Increased collagen deposition is a hallmark of systemic sclerosis (SSc). Several fibrogenic cytokines play a role in this sclerosis. The role of basic fibroblast growth factor (bFGF), the most potent fibrogenic cytokine, is poorly understood in SSc. Skin biopsies from forearm of 13 patients with SSc and 3 normal individuals were analyzed by immunohistochemistry using avidin biotin-system to amplify the signal. In addition serum levels of bFGF were also measured in 30 patients including these 13 and 23 healthy controls. Thirteen patients with SSc were all females and had a median age of 26.5 years, median disease duration of 2.25 years. Of these thirteen, seven had diffuse and six had limited disease. The skin biopsies from patients showed increased expression of bFGF in the basal layer of epidermis, dermis (periappendageal, perivascular, matrix tissue) as compared to normal tissues. The expression of bFGF did not correlate with duration of disease or skin score. In contrast, only low levels of bFGF were detectable in 4/30 sera from SSc patients as compared to 3/23 from healthy controls (p = ns). Overexpression of bFGF in skin of patients with SSc along with normal serum levels suggests that bFGF probably acts in an autocrine or paracrine manner in fibrogenesis.

Abstract
Superoxide radicals are produced in trace amounts by the mitochondrial respiratory chain. Most are removed rapidly by superoxide dismutase in the matrix. Superoxide is also known to react with glutathione. Reported values of the rate constant for this reaction range from 10(2) to in excess of 10(5) M(-1).s(-1). The magnitude of this rate constant has important physiological implications because, if it is at the upper end of the reported range, a significant proportion of mitochondrial superoxide will evade removal by superoxide dismutase, and will oxidize glutathione to the potentially harmful glutathionyl radical. Using EPR spectroscopy to monitor competition between glutathione and the spin trap 5,5-dimethyl-1-pyrroline N-oxide for reaction with superoxide, we have estimated that the rate constant for the reaction between superoxide and glutathione is only approximately 200 M(-1).s(-1). Hence superoxide dismutase will always out-compete glutathione for reaction with the superoxide radical, thereby preventing formation of the glutathionyl radical.

Abstract
OBJECTIVE The aim of the study was to evaluate whether the presence of normal ovarian tissue adjacent to an adnexal tumor (the 'ovarian crescent sign') could assist in the preoperative differential diagnosis of adnexal lesions. METHODS This was a prospective observational study including 100 women with a preoperative diagnosis of an adnexal mass. Demographic and biochemical data were collected and all women underwent a detailed transvaginal ultrasound scan. Tumor volume, morphological characteristics and Doppler features were recorded in each case. In addition, the tissue adjacent to the cyst was systematically examined for the presence of normal ovarian tissue. All the findings were compared to the final histological diagnosis. RESULTS Sixty-seven (67%) of the cysts removed were benign, nine (9%) were borderline and 24 (24%) women had invasive malignant lesions. Normal ovarian tissue was seen in 58/76 (76%) women with non-invasive lesions, and in one woman (4%) with an invasive malignancy. In the absence of normal ovarian tissue, ovarian cancer was diagnosed with a sensitivity of 96% and specificity of 76%. CONCLUSION The presence of normal ovarian tissue adjacent to an ovarian cyst is a useful morphological feature that may be used to help exclude an invasive ovarian malignancy in women with adnexal masses detected on ultrasound scan.

Abstract
OBJECTIVE To describe first-trimester ultrasound diagnosis and management of pregnancies implanted into uterine Cesarean section scars. METHODS All women referred for an ultrasound scan because of suspected early pregnancy complications were screened for pregnancies implanted into a previous Cesarean section scar. The management of Cesarean section scar pregnancies included transvaginal surgical evacuation, medical treatment with local injection of 25 mg methotrexate into the exocelomic cavity and expectant management. RESULTS Eighteen Cesarean section scar pregnancies were diagnosed in a 4-year period. The prevalence in the local population was 1 : 1800 pregnancies. Surgical treatment was used in eight women and it was successful in all cases. The respective success rates of medical treatment and expectant management were 5/7 (71%) and 1/3 (33%). Five women (28%) required blood transfusion and one woman (6%) had a hysterectomy. CONCLUSIONS Cesarean section scar pregnancies are more common than previously thought. When the diagnosis is made in the first trimester the prognosis is good and the risk of hysterectomy is relatively low.

Abstract
A retrospective review of medical records was performed to assess the incidence and type of significant complications encountered during laparoscopic hysterectomy Two hundred and sixty-five consecutive patients were reviewed between the years 1994 and August 2001. Two hundred and thirty-two laparoscopic vaginal hysterectomies and 33 total laparoscopic hysterectomies were performed. The operations were performed at Monash Medical Centre, a Melbourne tertiary public hospital, and two Melbourne private hospitals, by three surgeons. Ten significant complications occurred. There were two cases of ureteric fistula, two bladder injuries, two bowel obstructions, two postoperative haematomas, one case of a bladder fistula and one superficial epigastric artery injury. In-patient stay ranged from two to six days. Our complication and in-patient stay rates are consistent with previously reported rates.
