Channel Capacity Maximization using NQHN Approach at Heterogeneous Network

In present scenario, the high speed data transmission services has pushed limits for wireless communication network capacity, at same time multimedia transmission in real-time needs provision of QoS, therefore the network capacity and small cell coverage has comes with lots of challenges. Improving the channel capacity and coverage area within the available bandwidth is necessary to provide better QoS to users, and improved channel capacity for the FCUs and MCUs in network. In this paper, we are proposing an NQHN approach that incorporate with efficient power allocation, improving the channel capacity by optimized traffic scheduling process in a small cell HetNets scenario. This work efficiently handle the interference with maintaining the user QoS and the implemented power controller uses HeNB power as per the real time based approach for macro-cell and femto-cell. Moreover, we consider the real traffic scenario to check the performance of our proposed approach with respect to existing algorith

Clinicopathological study of hysterectomised specimens

Background: Hysterectomy is the commonest major surgical procedure performed in gynecology. It can be done by abdominal or vaginal route and with the help of laparoscopy. Hysterectomy is an effective treatment option for many conditions like fibroid, abnormal uterine bleeding, endometriosis, adenomyosis, uterine prolapse, pelvic inflammatory disease and cancer of reproductive organ when other treatment options are contraindicated or have failed, or if the woman no longer wishes to retain her menstrual and reproductive. The aim and objective of the study was to correlate indications of hysterectomy with histopathological findings in hysterectomised patients.Methods: A retrospective study was carried on 113 hysterectomised cases over a period of one year from June 2015 to May 2016. The data regarding the patient’s age, parity, clinical diagnosis, type of hysterectomy and histopathological diagnosis were reviewed by the records and analyzed.Results: A total of 113 cases of hysterectomies were studied. Hysterectomies were distributed over a wide age ranging from 20 years to 75 years. Most common age group was 41-50 years. Among hystectomies majority were done through vaginal route 86 (76.1%) and 26 (23%) cases were done through abdominal route. Most common clinical diagnosis was fibroid uterus in 44(38.9%) cases. Most of the hysterectomies were done for benign conditions. In final histopathological report most common diagnosis was fibroid uterus in 45(39.8%) hysterectomy specimens. It was correlated well with clinical diagnosis. Next most common histopathological diagnosis was Adenomyosis.Conclusions: Histopathological analysis correlated well with preoperative clinical diagnosis in majority of cases. The commonest indication and histopathological finding in our study was fibroid uterus. Next most common histopathological finding was Adenomyosis. Most commonly hysterectomies were done through vaginal route in our study

Correlation of sonographic prostate volume with international prostate symptom score in South Indian men

Background: Benign prostatic hyperplasia (BPH) is a common disease in old age individuals, usually starts around the age of 40 years, the prevalence of benign prostatic hyperplasia rises to more than 50% at 50 years of age to as much as 90% at the age of 85 years. Proven BPH patients suffer from moderate to severe lower urinary tract symptoms (LUTS) that are symptoms related to storage and voiding of urine. This study was to determine relationship between sonologically measured prostate Volume and international prostate symptom score (IPSS).Methods: Clinically symptomatic 126 patients in the age group of 40-89 years were studied. All the patients underwent Transabdominal sonography for the estimation of prostate volume and clinical questionnaire for international prostate symptom score.  Statistical Analysis by descriptive and analytical statistics using SPSS version 16. Chi-Square test used and P values ≤ 0.05 was considered to be statistically significant.Results: Among 126 individuals, The maximum number of patients, that is 45 patients had the prostate volume measuring 31-50 cc (35.7%), followed by 25 patients (19.8%) had the volume measuring more than 50 cc. Maximum number of patients 52 (41.3%) were having severe symptoms, 47 (37.3%) patients were having moderate symptoms and 27 patients   symptoms and 27 patients (21.4%) were having mild symptoms. Prostate volume had statistically significant but weak correlation observed with IPSS (r=0.40, p=0.001), Weak Stream (r=0.31, p=0.001) and urgency (r=0.31, p=0.001).Conclusions: Prostate volume had statistically significant but weak correlation observed with IPSS.

A study of uterine balloon tamponade for the management postpartum haemorrhage using Bakri balloon

Background: PPH is the most common cause of maternal morbidity and mortality around the world. Incidence of PPH is 2-4% following vaginal delivery and 6% following cesarean delivery in India. Uterine atony is the most common cause of PPH. Treatment of PPH involves medical treatment and surgical management. In between medical and surgical management of PPH comes uterine balloon tamponade which is simple, less invasive and can be managed with minimal training.Methods: A retrospective cohort study was done for 2 years at Vanivilas hospital, Bangalore medical college and research centre, Bangalore, Karnataka. Cases of atonic PPH managed using Bakri balloon were included in the study. The objective of the study was to study the effectiveness of uterine balloon tamponade using Bakri balloon in the management of atonic PPH and to study the maternal outcome.Results: In this study total of 50 cases were included. Women were in the age group of 18 to 33years. Regarding obstetric history, 22 (44%) were primigravida and 28 (56%) was multigravida. Among these 50 cases 8 (16%) women had undergone caesarean delivery and 42(84%) had vaginal delivery. All women received blood transfusion, 17 (34%) received blood and blood components (like PRBC, FFP AND platelets) and 33 (66%) cases received only PRBC transfusion. In these 50 cases, 32 (64%) required ICU admission for monitoring, remaining 18 (36%) were monitored in the labor-room. Bakri balloon was effective in 49 cases among 50. Success rate was 98%.Conclusions: Intrauterine balloon tamponade using Bakri balloon is effective for control of atonic PPH in majority of cases.

Role of sonography in the assessment of dengue fever with serological correlation

Background: Dengue, caused by a flavivirus has emerged as a major public health problem in the Indian subcontinent. This study was to assess severity of disease by ultrasound findings and to correlate ultrasound findings with blood platelet count.Methods: A Cross sectional study carried out on 210 subjects who had serologically proven dengue fever were included in the study. Ultrasound of abdomen, pelvis and thorax was performed and imaging features were analysed by descriptive and analytical statistics using SPSS version 16. Chi-Square test used and P values ≤ 0.05 was considered to be statistically significant.Results: Mean age of patients 42± 19 years with 106(50.5%) males and 104(49.5%) females. The Gall bladder wall thickening was noted in majority (92.8%) of the study subjects followed by Right peri-renal collection in 112(53.3%), Splenomegaly in 105(50.0%) subjects and Hepatomegaly in 66(31.4%). The sonographic abnormalities including Gall bladder wall thickening, Right, Left and Bilateral perirenal collection, Splenomegaly, Hepatomegaly, Right and Left pleural effusion, were significantly higher in study subjects with decreased platelet count.Ascites was the commonest finding in 76 study subjects with platelet count between 60000-79000 (36.2%) and in 144 study subjects (68.5%) in the 20-59 years age group. As the   platelet count decreased the severity of ascites increased and was statistically significant (p≤0.05).Conclusions: A patient who presents with sonographically recognizable complications is more likely to have disease that requires immediate and aggressive management.

Assessment of the Relationship Between Matrix Metalloproteinase-9 Promoter Gene Polymorphism and Chronic Periodontitis

Objective: To evaluate the association of MMP-9 promoter gene polymorphism in generalized chronic periodontitis patients of an Indian population. Material and Methods: Eighty patients were selected and divided into case and control groups (n=40). Patients included were aged 15-60 years of both genders and diagnosed with chronic periodontitis. Peripheral venous blood samples were obtained, and genomic DNA was isolated by a 'salting out' method. Three possible genotypes were distinguished by three distinct banding patterns, depending on the presence or absence of the Sph I restriction site: CC as allele 1, TT as allele 2, and CT, respectively. Statistical analysis was carried out by applying the Chi-squared test and One-way ANOVA. Results: There was a significant difference in MMP-9 genotypes between Chronic periodontitis patients and healthy controls. Odds ratios for CT genotype and combination of CT and TT genotypes were 3.125 (95% confidence interval, p=0.028) and 3.667 (95% confidence interval, p=0.006) relative to subjects with CC genotype, respectively. Conclusion: The present study revealed an association of MMP-9 (-1562 C/T) gene polymorphism with generalised chronic periodontitis
