    Reversible cerebral vasoconstriction syndrome (RCVS) is characterised by severe headache and is associated with reversible segmental vasoconstriction of cerebral arteries. Conditions associated with RCVS are commonly pregnancy with or without pre-eclampsia, neurological procedures, head trauma. Thunderclap headache is the chief clinical presentation. Visual disturbances and focal neurological deficits are also frequently encountered. Posterior reversible encephalopathy syndrome and RCVS are often overlapping and hence most cases of RCVS are diagnosed late. We reported a young primigravida who had no comorbidities presenting to the ER with elevated blood pressure and generalised tonic and clonic seizures. Post-delivery her headache persisted and clinically her neurological status started deteriorating. Later she was diagnosed as RCVS. Treatment is based on expert opinion. Nimodipine, nifedipine or verapamil have been used in most patients

    In general, satellite images suffer fromlow resolution (LR)due to the environmental disturbances such as fog and haze, which will degrade the visual quality of the images. In order to find the location or the persons, someone needs to enhance these satellite images to improve the perceptual quality of images. In this a novel resolution enhancement (RE) approach for satellite images is proposed. The proposed approach employeda dual tree complex wavelet transform (DT-CWT) based fusion algorithm in discrete and redundant wavelet domain to obtain a high resolute (HR) satellite images.Majorly, there are two stages in this algorithm, which includes the enhancement of a LR satellite images by enforcing the concept of both discrete and redundant wavelet (DRW) transforms together. Afterwards, this enhanced HR satellite image is given as a one of the source images to the approach of DT-CWT based image fusion for further enhancement of HR satellite image. Experimental analysis shown that the proposed fusion based satellite image enhancement is performed superior to the conventionalwavelet-based approaches like DWT-RE and DRWT-REin terms of peak signal to noise ratio (PSNR), mean square error (MSE) and structural similarity (SSIM) index

    Melanoma is the dangerous form of skin cancer. Rate of melanoma incidence have been increasingnowadays. It is found to be common among non-Hispanic white males and females, but survival rates are high if detected early. Due to the costs for dermatologists to examine every patient, there arises a need for an automated system to assess a patient‘s risk of melanoma using images of their skin lesions captured using a standard digital camera. One challenge in implementing such a system is locating the skin lesion in the digital image. In the proposed method the image is processed, segmented and spatially gray level dependency matrix (SGLD)features are extracted. Then the features are compared with the given database and classification is done using back propagated artificial neural network (BP-ANN). The proposed framework has higher accuracy compared to other tested algorithms

    INTRODUCTION: The infection of a wound can be defined as the invasion of organisms through tissues following a breakdown of local and systemic host defences, leading to cellulitis, lymphangitis, abscess and bacteraemia. Infections of surgical wounds are called as surgical site infections (SSIs). SSIs are defined as infections occurring within 30 days after a surgery or within one year if an implant is left in place after the procedure and affecting either the incision or deep tissue at the operation site. According to the National Nosocomial Infection Surveillance program (NNIS), it is classified into superficial, deep, organ/space infections. Source of SSIs include the patient‘s own normal flora, organisms present in the hospital environment that are introduced into the patient by medical procedures, specific underlying disease, trauma or burns which may cause a mucosal or skin surface interruption. SSIs are serious operative complications that occur in approximately 2% of surgical procedures and account for 20% of health care-associated infections. Many studies reported that SSIs rank third among common nosocomial infection next only tourinary tract and respiratory tract infections. Recent studies reported that SSI rate ranges from 19.4% to 36.5% 7all over the world, whereas in India it ranges from 3% to 12%. SSI remains a common and widespread problem that contributes to significant morbidity and mortality, prolongs hospital stay and consequently increasing health care cost. AIMS AND OBJECTIVES: 1. To find out the prevalence of SSI in this hospital. 2. To elicit the association between bacterial isolates and anatomical site of infection. 3. To identify the probable risk factors for development of surgical site infections. 4. To isolate and identify aerobic pathogenic bacteria from surgical site infections (SSI). 5. To determine the antimicrobial sensitivity pattern of pathogens. MATERIALS AND METHODS: This was a Hospital based Prospective Cross sectional study and carried out at the Department of Microbiology, Trichy SRM Medical College Hospital and Research Centre, Irungalur, Trichy, Tamilnadu. The study was carried out over a period of one year (May 2017 to April 2018). MATERIALS: Consecutive cases of both sexes and all adults belonging to various surgical wards and underwent surgical procedure during the study period comprising of elective as well as emergency were considered for the present study. Patients belonging to anyone of the following were excluded. 1. Paediatric cases. 2. Cases taken for second surgery at the same site for any reason. 3. Patients on immunosuppressant or with immunodeficiency status. 4. Patients on antibiotics already for any other infections. 5. Presence of infection elsewhere in the body or focal sepsis. RESULTS: The study, “Bacteriological Profile, Antibiogram and Risk Factors of Surgical Site Infections in a Tertiary Care Hospital” was carried out in the Department of Microbiology, Trichy SRM Medical college Hospital and research centre, Trichy and the results were analyzed for the Surgical site infections (SSIs) rate as per class of wound, type of surgery, antibiotic prophylaxis, risk factors, drug resistance and American society of anesthesiologist index. Prevalence of SSIs: A total of 2076 patientsunderwent different types of surgeries comprising of elective as well as emergency during a 12-month period (May 2017 – April 2018). The types of surgeries done in this hospital during the study period are listed in the table no.10. During the 12 consecutive months of study period, 116 surgical site infections were documented and hence,the overall prevalence of surgical site infection rate during the study period was 5.6%(n=116). Among the 2076 surgeries, abdominal surgeries constituted (n =739 ; 35.6%) the highest rate of SSI occurred in the category of exploratory laparotomy. 78 underwent exploratory laparotomy, 20 developed SSIs (25.6%). CONCLUSION: A total of 2076 patients underwent various surgeries including elective as well as emergency surgeries during consecutive 12 months commencing from May 2017 – April 2018. Standard methods were adopted to collect sociodemographic, clinical and microbiological data. SSIs were suspected in 134 patients. The clinical signs and symptoms started appearing from 4th day onwards and more no of cases manifested features of infection either on 5th or 6th postoperative day. 18 samples showed no growth and the remaining 116 samples yielded 124 isolates (8 were polymicrobial infections). The prevalence rate of SSI in our hospital during the study period was 5.6%.The SSI were more common in abdominal surgeries highest being in laparotomy surgeries (20/78; 25.6%). The odd‘s ratio for the development of SSIs in emergency cases was 0.57 and among males was 1.61. All these cases had one or other risk factors also. The occurrence of SSIs was high in dirty (41.2%) and contaminated surgical wounds (11.2%) when compared to clean surgeries. Interestingly, SSIs were more among those belonging to age group 16-24 yrs (11.9%) and odd‘s ratio was 2.45. SSI was independent of prophylactic antibiotic administration. During the study period, SSIs developed in all patients who received prophylactic antibiotics thereby indicating that prophylactic antibiotics did not protect the individual from developing SSIs. Smear studies of 134 samples revealed pus cells in all but smear had bacterial agents in only 37. For practical purposes, SSIs have to be considere

    Hydroponics play most significant role in augmenting fodder shortage and helps for dairy production efficiently. A study was conducted to assess the performance and suitability of different crops under low cost green house hydroponic fodder production unit at SHE&CS Krishi Vigyan Kendra, Yagantipalle. Four varieties of cereals grains and four verities of Pulses were tested. One kilogram grain each of the variety was soaked for 12 hours in water for sprouting in air tight condition for 36 hours. The sprouted seed was spread in trays of size 2.5 ft X 1.5ft and kept in the Hydroponic Unit. Automatic sprinkling of water was managed by cyclic timer. Chemical fertilizer was not used. Data on sprouted seed weight and weight of biomass after 5 days was recorded using electronic weighing balance. The high biomass yield after 5days in cereals was recorded in Bajra followed by sorghum, Barley and Maize. Among pulses Pillipesara yielded highest weight followed by Cowpea, Lucerne and Horse gram. Highest plant height among cereals was recorded in Barley and cowpea in pulses. The difference among all the varieties in respect of biomass yield and plant height was found to be significant. Negative correlation was found between plant height and biomass yield

    Background: Natural menopause or surgical menopause is associated with endocrinological changes and alteration in bone and mineral metabolism. Hence this study was conducted to assess the bone mineral density changes in women with surgical menopause. Methods: This is a prospective observational study conducted in the department of obstetrics and gynaecology at Sri Ramachandra medical college, which is a tertiary care teaching hospital. 60 women with surgical menopause were included in the study. BMD was assessed by dual energy X-ray absorptiometry at the lumbar spine and hip joint. All the data was entered in Microsoft excel spread sheet and analysed by using SPSS software.Results: Among 60 study subjects, 41 individuals had a normal BMD, 16 had osteopenia, and 3 were diagnosed with osteoporosis. Osteopenia and osteoporosis is significantly higher in patients who had undergone hysterectomy with removal of ovaries. Observations of osteopenia and osteoporosis were significantly higher with increasing number of years post hysterectomy.Conclusions: Prevalence of osteoporosis is high in patients who undergo hysterectomy. Oophorectomy is associated with postoperative bone loss. Targeted management strategies should include routine BMD assessment and hormone therapy improves management of bone health in this population. Further more studies are needed in large populations to test alternative treatments for post oophorectomy osteoporosis

    Get PDF
    Leaves paste of Coleus aromaticus is used as a traditional remedy for urolithiasis in India. In the present study, the anti urolithiatic activity of Coleus aromaticus was investigated in ethylene glycol induced urolithiatic rats. There was a significant increase in the levels of calcium oxalate crystals in the kidneys as well as lipid levels in the blood serum. Treatment with hydro alcoholic extract of C.aromaticus leaves (CALHAE) significantly reduced cholesterol levels at 300 and 600 mg/kg, and triglyceride levels at 600 mg/kg in urolithiatic rats. Histopathalogical reports confirmed that chronic administration of CALHAE (300 and 600 mg/kg) diminished number of calcium oxalate crystals in kidneys. CALHAE has shown reduction in thiobarbituric acid reactive substances (TBARS) in urolithiatic rats. Moreover, CALHAE showed potent in vitro antioxidant activity in DMPD, ABTS radicals (MnO2 method). Results from these studies support the safe and effective use of C.aromaticus leaves for urolithiasis treatment.Keywords: Coleus aromaticus, Calcium oxalate crystals, Hypolipidemic activity, Antioxidant activit
