Chronic non puerperal uterine inversion secondary to uterine leiomyoma misdiagnosed as advanced cervical cancer: a rare case report
Uterine inversion is an uncommon complication of parturition which often occurs in the immediate postpartum period. The chronic non puerperal uterine inversion is a rare gynaecological clinical condition which usually results from tumour arising from the fundus of the uterus. Here we are present a case of 45 year old lady with non-puerperal chronic uterine inversion secondary to fundal sub mucous fibroid polyp which was initially misdiagnosed as carcinoma cervix. An attempt at vaginal restoration and removal was difficult. Hysterectomy was done by vaginal approach. Pre and Postoperative course in the hospital was uneventful. Early diagnosis and appropriate surgical treatment of the inverted uterus are important to prevent further complications
A study of changing trends of maternal mortality at the tertiary care centre, MMC & RI Mysore, India
Background: Maternal mortality is a reflection of the care given to women by the society. It is tragic that deaths occur during the natural process of child birth and most of them are preventable. Aims and objectives: To study the maternal mortality and the causes resulting in maternal death over 5 years in a tertiary care centre, Cheluvamba hospital, MMC & RI, Mysore. To find out avoidable factors and use information thus generated to reduce maternal mortality.Methods: A retrospective study of all maternal deaths from June 2008 to June 2013. All maternal deaths were reviewed and studied in detail including admission death interval and cause of death. Results: Maternal mortality ratio ranged between 262 to 109/100000 births. The causes of death were hypertensive disorders (30.4%), haemorrhage (24.8%), anaemia (14.8%), sepsis (6.8%) and others (23.2%). Maximum deaths (70.6%) occurred in women between 20-29 years of age, multigravida contributed to 54.96% of maternal mortality. 42 % were unbooked, 97% were referred cases. Conclusions: Overall maternal mortality was 215/100000 live births. Maternal deaths due to direct obstetric causes were 87% and indirect were 13 %. The causes of potentially preventable deaths include haemorrhage, anaemia, sepsis, disseminated intravascular coagulation and its complications. Hypertensive disorders were the leading cause of death, followed by haemorrhage. Anaemia was an important indirect cause of death. Most maternal deaths are preventable by optimum utilization of existing MCH facilities, identifying the bottlenecks in health delivery system, early identification of high risk pregnancies and their timely referral to tertiary care centre
Micro-Flow Imaging: Flow Microscopy Applied to Sub-visible Particulate Analysis in Protein Formulations
The need to monitor, measure, and control sub-visible proteinaceous particulates in biopharmaceutical formulations has been emphasized in recent publications and commentaries. Some of these particulates can be highly transparent, fragile, and unstable. In addition, for much of the size range of concern, no practical measurement method with adequate sensitivity and repeatability has been available. A complication in measuring protein particulates in many formulations is the simultaneous presence of other particle types such as silicone micro-droplets, air bubbles, and extrinsic contaminants. The need has therefore been identified for new analytical methods which can accurately measure and characterize sub-visible particulates in formulations. Micro-flow imaging has been shown to provide high sensitivity in detecting and imaging transparent protein particles and a unique capability to independently analyze such populations even when other particle types are present
Survival and development of Campoletis chlorideae on various insect and crop hosts: implications for Bt-transgenic crops
The parasitic wasp, Campoletis chlorideae is an important larval parasitoid of Helicoverpa armigera a serious pest of cotton, grain legumes and cereals. Large-scale deployment of Bt-transgenic crops with resistance to H. armigera may have potential consequences for the development and survival of C. chlorideae. Therefore, we studied the tritrophic interactions of C. chlorideae involving eight insect host species and six host crops under laboratory conditions. The recovery of H. armigera larvae following release was greater on pigeonpea and chickpea when compared with cotton, groundnut and pearl millet. The parasitism by C. chlorideae females was least with reduction in cocoon formation and adult emergence on H. armigera larvae released on chickpea. Host insects also had significant effect on the development and survival of C. chlorideae. The larval period of C. chlorideae was prolonged by 2-3 days on Spodoptera exigua, Mythimna separata and Achaea janata when compared with H. armigera, Helicoverpa assulta and Spodoptera litura. Maximum cocoon formation and adult emergence were recorded on H. armigera (82.4% and 70.5%, respectively) than on other insect hosts. These studies have important implications on development and survival of C. chlorideae on alternate insect hosts on non-transgenic crop plants, when there is paucity of H. armigera larvae on transgenic crops expressing Bt-toxins
Antixenosis and antibiosis mechanisms of resistance to pod borer, Helicoverpa armigera in wild relatives of chickpea, Cicer arietinum
The noctuid pod borer, Helicoverpa armigera is one of the most damaging pests of chickpea, Cicer arietinum. The levels of resistance to H. armigera in the cultivated chickpea are low to moderate, but the wild relatives of chickpea have exhibited high levels of resistance to this pest. To develop insect-resistant cultivars with durable resistance, it is important to understand the contribution of different components of resistance, and therefore, we studied antixenosis and antibiosis mechanisms of resistance to H. armigera in a diverse array of wild relatives of chickpea. The genotypes IG 70012, PI 599046, IG 70022, PI 599066, IG 70006, IG 70018 (C. bijugum), ICC 506EB, ICCL 86111 (cultivated chickpea), IG 72933, IG 72953 (C. reticulatum), IG 69979 (C. cuneatum) and IG 599076 (C. chrossanicum) exhibited non preference for oviposition by the females of H. armigera under multi-choice, dual-choice and no-choice cage conditions. Based on detached leaf assay, the genotypes IG 70012, IG 70022, IG 70018, IG 70006, PI 599046, PI 599066 (C. bijugum), IG 69979 (C. cuneatum), PI 568217, PI 599077 (C. judaicum) and ICCW 17148 (C. microphyllum) suffered significantly lower leaf damage, and lower larval weights indicating high levels of antibiosis than on the cultivated chickpea. Glandular and non-glandular trichomes showed negative correlation with oviposition, while the glandular trichomes showed a significant and negative correlation with leaf damage rating. Density of non-glandular trichomes was negatively correlated with larval survival. High performance liquid chromatography (HPLC) fingerprints of leaf surface exudates showed a negative correlation of oxalic acid with oviposition, but positive correlation with malic acid. Both oxalic acid and malic acid showed a significant negative correlation with larval survival. The wild relatives exhibiting low preference for oviposition and high levels of antibiosis can be used as sources of resistance to increase the levels and diversify the basis of resistance to H. armigera in cultivated chickpea
Bridging conventional and molecular genetics of sorghum insect resistance
Sustainable production of sorghum, Sorghum bicolor (L.) Moench, depends on effective control of insect pests as they continue to compete with humans for the sorghum crop. Insect pests are a major constraint in sorghum production, and nearly 150 insect species are serious pests of this crop worldwide and cause more than 9% loss annually. Annual losses due to insect pests in sorghum have been estimated to be 248 million annually. The major insect pests of sorghum on a global basis are the greenbug, sorghum midge, sorghum shoot fly (Atherigona soccata Rond.), stem borers (Chilo partellus Swin. and Busseola fusca Fuller), and armyworms (Mythimna separata Walk and Spodoptera frugiperda J.E. Smith). Recent advances in sorghum genetics, genomics, and breeding have led to development of some cutting-edge molecular technologies that are complementary to genetic improvement of this crop for insect pest management. Genome sequencing and genome mapping have accelerated the pace of gene discovery in sorghum..
Characterization of Particles in Protein Solutions: Reaching the Limits of Current Technologies
Recent publications have emphasized the lack of characterization methods available for protein particles in a size range comprised between 0.1 and 10 μm and the potential risk of immunogenicity associated with such particles. In the present paper, we have investigated the performance of light obscuration, flow microscopy, and Coulter counter instruments for particle counting and sizing in protein formulations. We focused on particles 2–10 μm in diameter and studied the effect of silicon oil droplets originating from the barrel of pre-filled syringes, as well as the effect of high protein concentrations (up to 150 mg/ml) on the accuracy of particle characterization. Silicon oil was demonstrated to contribute significantly to the particle counts observed in pre-filled syringes. Inconsistent results were observed between different protein concentrations in the range 7.5–150 mg/ml for particles <10 μm studied by optical techniques (light obscuration and flow microscopy). However, the Coulter counter measurements were consistent across the same studied concentration range but required sufficient solution conductivity from the formulation buffer or excipients. Our results show that currently available technologies, while allowing comparisons between samples of a given protein at a fixed concentration, may be unable to measure particle numbers accurately in a variety of protein formulations, e.g., at high concentration in sugar-based formulations
Successful management of aggressive fibromatosis of the neck using wide surgical excision: a case report
<p>Abstract</p> <p>Introduction</p> <p>Aggressive fibromatosis is a benign tumor, thought to arise from deep musculoaponeurotic structures, rarely found in the head or neck. However, when it does occur in the head and neck region, it tends to be more aggressive and associated with significant morbidity, which may be attributed to the vital vascular, neurological or anatomical structures in close proximity.</p> <p>Case presentation</p> <p>We report the case of a 39-year-old Pakistani man who presented with a two-month history of a lump on the right side of his neck. The mass was excised and histopathological analysis revealed a case of aggressive fibromatosis.</p> <p>Conclusion</p> <p>Due to the rarity of the condition no guidelines are available on the indications and extent of each modality. Due to its aggressive behavior and tendency to invade local structures and recur, a multi-modality management strategy is usually employed. On the basis of this case, we suggest that aggressive surgery is a viable management option and may be successfully used as a single modality treatment.</p
