Abstract | Full Text |
Abstract :This paper takes the propagation characteristics of heavy metals and the judgment of the location of pollution sources as the research objects, aiming to analyze the propagation characteristics of different heavy metals. Firstly, the Gaussian diffusion model is conducted to establish the propagation characteristics model of heavy metal pollutants in the atmosphere. Then, based on the law of conservation of mass and the law of two-dimensional diffusion, the two-dimensional diffusion model is adopted to establish the propagation characteristics model of heavy metals in soil moisture. According to these two models, the nonlinear differential equations are established respectively, revealing that the characteristics of the two propagation ways are related to space, time, diffusion coefficients, and other factors. Then, in the light of the propagation characteristics of different heavy metals, the least square method is applied to reduce the data calculation error and obtain the specific location of the pollution source. Finally, through establishing the three-dimensional diffusion model of heavy metal diffusion by introducing artificial control, speed and angle of prevailing wind direction, and other factors, the model is further optimized. The establishment of this model provides an important theoretical basis and guiding significance for the future study of heavy metal pollutants. |

Abstract :To form the basis of a respiratory disease model in rats by investigating the microbial distribution and composition in the lower respiratory tracts of normal rats. Methods: DNA was extracted from the intestine, trachea, bronchus and lung samples collected from healthy rats under sterile conditions. The 16S rDNA V4-V5 region was sequenced using Illumina high-throughput technology. Results: The sequencing results showed that there was no significant difference in abundance and species diversity of microbiota between the lower respiratory and the intestine. The microbiota structure analysis showed samples from lungs and intestinal shared similarity. However, the dominant species at the levels of phylum, family, and genus diverged. The similarity analysis showed that the lung microbiota were different from the intestines. The linear discriminant analysis showed significantly different species in different tissues; function prediction also showed different microbiota function in different tissues. Conclusions: These results suggest that bacterial colonization depends on the sample’s anatomical location. The human pathogen Acinetobacter lwoffii was also detected in the rat lower respiratory tract samples. |

Abstract | Full Text |
Abstract :BACKGROUND: Therapeutic Plasma Exchange (TPE) is an apheresis treatment in which the plasma component of blood is removed and replaced with supplemental fluids. It is an immunomodulatory treatment that has been reported to be a successful therapeutic procedure for the treatment of severely compromised patients with myasthenia gravis when given at short intervals. TPE is known to have a comparable efficacy to intravenous immunoglobulin (IVIG) in the treatments of patients with moderate to severe myasthenia crisis. METHODOLOGY: We report a case of a 47year old male patient with severe myasthenia crisis. He was managed using cobe spectra version 6.1 to carry out an automated TPE, with a suboptimal response and subsequent use of IVIG resulting in full recovery. This report highlights the possible factors that may hinder optimal response of a patient with Myasthenia crisis to TPE procedure in a poor resource setting. CONCLUSION: TPE is an essential immunomodulatory therapy in the management of acute myasthenia crisis whether given alone or in combination with immunosuppressive drugs. There can be a rebound overproduction of the offending autoantibodies in MG following TPE which can be cleared from circulation using immunosuppressive therapy. |

Abstract | Full Text |
Abstract :Brucellosis is an infectious debilitating, acute or sub-acute febrile illness usually marked by an intermittent or remittent fever accompanied by malaise, anorexia and prostration, and which, in the absence of specific treatment, may persist for weeks or months. The aim of this study was to determine the relationship between Socio-Demography Characteristics and prevalence of brucellosis among community members in Kenya. A case of Mandera East Sub-county, Mandera County, Kenya. The study was descriptive cross sectional study which collected both qualitative and quantitative data from where a sample of 420 respondents was systematically selected from heads of 2,617 households form Mandera East Sub-county. The study instruments included questionnaire, Focus Group Discussion guide and Interview Guide. Blood samples were screened for brucellosis using Rose Bengal Plate Test (RBPT) and the positive sera were subjected through Serum Slow Agglutination Test (SSAT) which acted as a confirmatory test. Data was analyzed using SPSS Version 20 and results of the study presented in frequencies and percentages in Tables and Figures. Ethical issues were observed and consent sought from the respondents. Rose Bengal Plate Test (RBPT) indicated a prevalence of 24.8% (95% CI: 20.0–29.6) and Serum Slow Agglutination Test (SSAT) indicated that the prevalence was at 14.3% (95% CI: 8.7–19.9) among the respondents. The study showed that the seroprevalence was higher among the male respondents (98%; n=103) as detected through RBPT and (98%; n=57) confirmed through SSAT. There was significant relationship between the gender and seroprevalence as tested through RBPT (P<0.001). |

Abstract | Full Text |
Abstract :Background: Maternal health remains today, one of the major public health concerns in developing countries. Maternal deaths and newborn deaths usually occur within 48 hours of delivery. In Cameroon, despite all the initiatives set up by the Ministry of Public Health to reduce the mortality rate, the situation remains alarming in terms of postnatal consultation; this is much more felt in the West region of Cameroon, which is one of the most affected regions because 43.1% of women who give birth in hospitals do not return to postnatal consultation and this rate is higher than the national average with a value of 21.5%. Objective:This work aims to determine the factors influencing postnatal follow-up in the Bafang Health District. Methodology: This is a cross-sectional descriptive study for analytical purposes, carried out in the Bafang Health District between January 1 to November 30, 2017. Our study population consisted of all women of childbearing age living in the Bafang Health District during the study period. The variables studied were sociodemographic characteristics, socio-cultural characteristics and the provision of care. Results: Analysis carried out during this study, it appears that, the person who informs the women on the dates of rendez-vous during the CPoN (OR = 2.92; [95%CI = 1.16-7,]; p-value = 0.02), women who think the appropriate period of postnatal follow-up is 6 weeks postpartum (OR = 4.27, [95%CI = 1.47-12.39], p-value = 0.00 ) and those who massage the abdomen after childbirth (OR = 2.62, [95%CI = 1.34 - 5.12], p-value = 0.00) are more likely to have knowledge about follow-up postnatal. While women who have no knowledge of postnatal follow-up (OR = 0.18, 95%CI = 0.07-0.45, p-value = 0.00) are less likely to have more knowledge. Conclusion: Lack of knowledge of the existence and importance of postnatal consultation (CPoN), traditional practices are the factors that influence postnatal follow-up in the Bafang Health District. A good and effective care for women after childbirth requires increased awareness campaigns at the hospital level as well as in community settings. |

Abstract | Full Text |
Abstract :Background: Tuberculous meningitis is defined as an inflammatory response to mycobacterial bacterial infection of the pia, arachnoid and CSF of the subarachnoid space. It is a dangerous form of extrapulmonary tuberculosis because it can cause permanent neurological disabilities and even death. Stroke is a devastating complication which further increase the morbidity and mortality in the disease. Matrix metalloproteinases are endopeptidases which degrade all the components of the extracellular matrix and thus have potential to disrupt blood brain barrier and cause CNS damage. Matrix metalloproteinases have been associated with pathophysiology of ischemic stroke. MMP levels in serum and CSF have also been seen to rise with advancing stage of TBM. So it is postulated that MMP may have role in the pathophysiology of stroke in TBM and may serve as a biomarker to predict stroke in TBM. Aims: To compare Serum Matrix metalloproteinase-9 in patients with Tuberculous Meningitis with and without Stroke and correlate it with various clinical, biochemical and radiological features of TBM. Methods: 40 Patients of probable or definite TBM and 40 age and sex matched patients of TBM with clinical stroke were enrolled in the study and formed two groups i.e. cases and controls. The two groups were compared for various clinical parameters, biochemical parameters (CSF cytology, glucose and protein), neuroimaging parameters and serum MMP-9 levels. Serum MMP-9 was estimated by ELISA method. Results: Serum MMP-9 levels were (224 ± 261.627 ng/ml) in cases and (157.23 ± 197.155 ng/ml) controls, which though higher in cases but no difference was statistically significant (p value 0.157) between two groups. Also there was no correlation between the serum MMP-9 levels and various clinical features (duration of illness, fever, headache, vomiting, weight loss, seizure, hemiparesis), CSF characteristics (protein, sugar and cytology) and radiological findings (tuberculoma, and hydrocephalus). Conclusion: we conclude that MMP-9 levels is not correlated with occurrence of stroke in TBM. MMP-9 levels were not increased with severity of disease, complications and outcomes. |

A Rare Case of Spindle Cell Neoplasm of Rectum |
Author : Shantata J. Kudchadkar ; Jayesh Sagar |
Abstract | Full Text |
Abstract :Spindle cell neoplasms usually occur in head, neck, orbit, soft tissues of scalp and along the upper aerodigestive tract. They are relatively uncommon in lower gastrointestinal tract and represent a distinct clinical entity. Increased awareness is required among colorectal surgeons and pathologists due to their benign nature & uncertain etiology, to avoid misdiagnosis of rectal cancer. Definitive diagnosis necessitates immunohistochemical analysis. We present an unusual case of spindle cell neoplasm of rectum in an asymptomatic elderly gentleman, detected on screening colonoscopy. Following thorough evaluation with MRI pelvis, CT scan thorax, abdomen, pelvis with contrast and multidisciplinary meeting discussion (MDT) at our institution, he was successfully treated with a specialized minimally invasive approach (TAMIS). Histopathology with immunohistochemistry confirmed the diagnosis of spindle cell neoplasm. As they are uncommon in colorectum & non-invasive, management and long-term follow-up is still under study. These lesions should be differentiated from other stromal tumours in GIT. |
