Pyometra is one of the most common uterine pathologies of intact bitch at middle to advanced age. In the early stages, the disease shows subtle changes, making diagnosis a challenge. In contrast, at later stages, it manifests as potentially life-threatening systemic inflammatory response syndrome. Ultrasonographic examination of the uterus aids in the diagnosis, although it has limitation in ascertaining the clinical severity of pyometra. Moreover, differentiation of cystic endometrial hyperplasia from pyometra could not be discerned with greater accuracy. Therefore, false negative diagnosis of pyometra patients leads to development of systemic inflammatory response, which delays administration of therapies and results in deaths during early course of treatment. Further, indiscriminate use of broad-spectrum antimicrobials at higher dose in false positive cases considerably contributes to the rising pool of drug resistant pathogens, thereby increasing the risk of case fatality due to sepsis in a long-term. Monitoring the circulating pro-inflammatory cytokines, acute phase proteins, endotoxin, growth factors and inflammatory mediators is the current trend in pyometra research, especially for developing diagnostic and prognostic biomarkers. The present review deals with the prospects of developing diagnostic and prognostic biomarkers in the canine pyometra.

Neotectonic investigations using morphotectonic parameters such as basin asymmetry, drainage anomalies, digital data interpretation and geomorphic field evidences were carried out in Satluj river valley downstream of Khab in the Kaurik Chango Fault (KCF) zone. The study reveals the presence of a northsouth trending fault which is similar to the KCF. Unpaired, tilted terraces, V shaped valleys, deep gorges and lakes are the manifestations of fault movement in the area. Presence of deformation structures preserved in the palaeolake profile at Morang indicates that the area has also been seismically active in the past. In this paper we present a conceptual model of the formation of lakes in KCF zone. Morphometric analysis was carried out with the help of Digital Elevation Models (DEMs) and field investigations.

The Himalayan mountain range is an internationally recognised landscape but one under increasing developmental threat. The lower Himalayan region possesses immense potential for hydropower generation but is also highly susceptible to tectonic deformation and mass wasting, especially landslides. Susceptibility to landslides increases markedly with human activity, especially large scale developmental projects. The impacts of massive hydropower plant construction in the Bhagirathi Valley, Uttarkhand, India on the generation of landslides are the focus of this study. Whilst many positive impacts derive from such projects, devastating negative impacts also accrue. The frequency and characteristics of land sliding within the sphere of influence of the construction sites of the various hydropower plant components were investigated. Landslide frequency was related to parameters of geology, prior land use, drainage density, slope steepness and location in terms of construction aspect. Landslide frequency was found to be greatest in gneissic terrain as well as on previously agricultural and forested lands. Statistical analysis revealed significant relationships between landslide frequency with slope and, frequency with construction aspect, especially the construction of access roads. As with other studies, road construction is the key initiator of land sliding due to slope over steepening and the indiscriminate dumping of debris. The study concludes with recommendations for reducing the frequency and magnitude of mass wasting in this environment.

Objective: To compare the effect of intraperitoneal ropivacaine with placebo for post-operative pain management in patients undergoing laparoscopic cholecystectomy. Material and Methods: All patients were pre-medicated with glycopyrrolate 0.2 mg, ondansetron 4 mg and ranitidine 150 mg intravenously half an hour prior to induction of anesthesia. All patients were given standard general anaesthesia with propofol (2-2.5 mg/kg), fentanyl 2 μg/kg, and succinylcholine (2 mg/kg) to facilitate tracheal intubation. Anesthesia was maintained with 60% N2O in oxygen with 0.5% to 1% Halothane. Group A: Patients received 20 ml of 0.9% normal saline as placebo (n = 25). Group B: Patients received 20 ml of 0.5% ropivacaine (n = 25). Results: The age and sex distribution of both the groups was similar. The heart rate, systolic & diastolic blood pressure, mean blood pressure and mean trend of SpO2 in both groups remained similar over the periods. The mean VAS varied considerably within (between time) and between the groups (treatment) and was especially comparatively higher in Group A at initial hours 15 min to 30 min and at end hours 12-24 hrs as compared with Group B. On an average, the frequent dosing of rescue analgesia and mean No. of rescue analgesia doses were higher in Group A followed by Group B. In both groups, the treatment related adverse events were mostly emetic symptoms and shoulder pain with the highest being in Group A. Conclusion: We conclude that intraperitoneal instillation of local anaesthetic is an easy, cheap, and non-invasive method which provides good analgesia in the immediate postoperative period after laparoscopic surgery.
