Ovarian enterobiasis: a case report
Enterobius vermicularis (the pinworm) is the most common intestinal nematode in gastrointestinal tract of humans. It commonly infests the lumen of the intestine but on rare occasions has been found in the wall or in the tissues outside the gastrointestinal tract; female genital tract and peritoneum being the commonest sites. It is usually seen as an incidental finding. This is a case of 29-year-old female presented for elective sterilization. A tiny nodule was noted on the surface of ovary during procedure which was sent for histopathological examination. Lesion was composed of necrotic areas and inflammatory cells with cross section of a degenerated worm. The features of the eggs were diagnostic of Enterobius vermicularis. Multiple histologic sections may be required to establish diagnosis in older lesions as in this case
Benign giant cell tumor of bone with pulmonary metastasis- report of two cases and review of literature
Tumors that are metastasizing generally considered as malignant. But there are exceptions. Giant cell tumor of bone is well known for its potential to metastasize without sarcomatous transformation. Potential of benign GCT to metastasize was first reported by Jaffe et al in 1940. Prevalence of pulmonary metastasis in benign GCT is between 1-9%. Factors favoring metastasis include recurrence of tumor, surgical manipulation of initial bone tumor, location of femur etc. Peripheral or basilar portion of pulmonary parenchyma is involved commonly. Eventhough death reported in 16-25% of cases, overall it has a favorable prognosis. Surgical resection is preferred treatment for pulmonary metastasis. In the present study 2 case studies were done. In 1st study 18 year old female, known case of GCT Lt tibia, with history of curetting and cementing presented with pain and swelling at same site and pulmonary metastasis 1 year later. Biopsy from initial as well as recurrent tumor confirmed benign GCT without any features of atypia, mitosis or necrosis. Aspirate from pulmonary lesion showed osteoclastic giant cells. No treatment given to metastatic deposits and is asymptomatic even though size of pulmonary lesions is increasing. And in second study a 22 year old female, with past history of GCT referred to our institution for evaluation of lung lesion detected in X-ray. Patient underwent metastatectomy here and histopathology was similar to that of bone lesion. There was no evidence of sarcomatous transformation both in initial and recurrent lesion. Patient is asymptomatic other wise and doing well
Ophiorrhiza, a promising herbaceous source of the anticancer compound camptothecin
Camptothecin is an important source for the synthesis of some of the major anti-cancer agents such as irinotecan and topotecan. Traditional source of camptothecin are prominently woody plants such as Camptotheca acuminata Decne. and Nothopodytes nimmoniana (Graham) Mabb., and the increasing demand for camptothecin leads to the level of threatening their existence. Ophiorrhiza species composed of herbaceous plants with quick growth characteristics which are reported as alternative source of camptothecin. The present review focus on taxonomical status, traditional uses, biological activities and phytochemical constituents with a special attention in bioproduction of camptothecin from Ophiorrhiza species and its future prospects

Revised ISHAM-ABPA working group clinical practice guidelines for diagnosing, classifying and treating allergic bronchopulmonary aspergillosis/mycoses
BACKGROUND: The International Society for Human and Animal Mycology (ISHAM) working group proposed recommendations for managing allergic bronchopulmonary aspergillosis (ABPA) a decade ago. There is a need to update these recommendations due to advances in diagnostics and therapeutics. METHODS: An international expert group was convened to develop guidelines for managing ABPA (caused by Aspergillus spp.) and allergic bronchopulmonary mycosis (ABPM; caused by fungi other than Aspergillus spp.) in adults and children using a modified Delphi method (two online rounds and one in-person meeting). We defined consensus as â„70% agreement or disagreement. The terms "recommend" and "suggest" are used when the consensus was â„70% and <70%, respectively. RESULTS: We recommend screening for A. fumigatus sensitisation using fungus-specific IgE in all newly diagnosed asthmatic adults at tertiary care but only difficult-to-treat asthmatic children. We recommend diagnosing ABPA in those with predisposing conditions or compatible clinico-radiological presentation, with a mandatory demonstration of fungal sensitisation and serum total IgE â„500â
IU·mL-1 and two of the following: fungal-specific IgG, peripheral blood eosinophilia or suggestive imaging. ABPM is considered in those with an ABPA-like presentation but normal A. fumigatus-IgE. Additionally, diagnosing ABPM requires repeated growth of the causative fungus from sputum. We do not routinely recommend treating asymptomatic ABPA patients. We recommend oral prednisolone or itraconazole monotherapy for treating acute ABPA (newly diagnosed or exacerbation), with prednisolone and itraconazole combination only for treating recurrent ABPA exacerbations. We have devised an objective multidimensional criterion to assess treatment response. CONCLUSION: We have framed consensus guidelines for diagnosing, classifying and treating ABPA/M for patient care and research.</p
