Clinical assessment and grading of back pain in horses

Background@#The clinical presentation of horses with back pain (BP) vary considerably with most horse's willingness to take part in athletic or riding purpose becoming impossible.However, there are some clinical features that are directly responsible for the loss or failure of performance. @*Objectives@#To investigate the clinical features of the thoracolumbar region associated with BP in horses and to use some of the clinical features to classify equine BP. @*Methods@#Twenty-four horses comprised of 14 with BP and 10 apparently healthy horses were assessed for clinical abnormality that best differentiate BP from normal horses. The horses were then graded (0–5) using the degree of pain response, muscular hypertonicity, thoracolumbar joint stiffness and overall physical dysfunction of the horse. @*Results@#The common clinical features that significantly differentiate horses with BP from non-BP were longissimus dorsi spasm at palpation (78.6%), paravertebral muscle stiffness (64.3%), resist lateral bending (64.3%), and poor hindlimb impulsion (85.7%). There were significantly (p < 0.05) higher scores for pain response to palpation, muscular hypertonicity, thoracolumbar joint stiffness and physical dysfunction among horses with BP in relation to non-BP. A significant relationship exists between all the graded abnormalities. Based on the cumulative score, horses with BP were categorized into mild, mild-moderate, moderate and severe cases. @*Conclusions@#BP in horse can be differentiated by severity of pain response to back palpation, back muscle hypertonicity, thoracolumbar joint stiffness, physical dysfunctions and their cumulative grading score is useful in the assessment and categorization of BP in horses.

Mineralization and mobilization of biosolids phosphorus in soil: A concise review

Biosolids are the product of wastewater or municipal solid waste collected through sewerage treatment; theprocesses of obtaining the biosolids involve various treatment processes, which include digestion, thermalstabilization, thickening, dewatering, and drying, in order to obtain free pathogen granules. These processesundergone by wastewater in the treatment plant ultimately clean the wastewater and remove the solids whichare further treated to an acceptable standard for beneficial soil amendments. The application of biosolids areconsidered to improve soil organic matter, moisture content, and provided essential nutrients, such as nitrogenand phosphorus in arable land as potential plant nutrients supplements for crop optimum yield. Incubationstudies on the biosolids-amended soils have shown significant increases in soil phosphorus content beingreleased as plant available P in the soil, and therefore could be a good source of phosphorus in deficientnative phosphorus soil. Field-scale experiments on wheat are grown with sewage sludge have also shown yieldproduction comparable to mineral fertilizer-treated soils. This review is thereby aimed at explaining the conceptbehind the mineralization and mobilization of biosolids phosphorus in soil. In this review paper, an overviewof the method of preparations, origin, and sources, its application in agriculture and the environment, chemicalcomposition, the environmental risk, soil amendments potentials of the biosolid sand regulatory, and globalperspective of sewage sludge disposal all are reviewed. From the review, it was concluded that mineralizationand mobilization of biosolids phosphorus in soil have beneficial input to both environment and soil nutrientamendment. It is thereby recommended that more research studies should be carried out on the mineralizationand mobilization of another essential element, such as nitrogen and biochar although more research should bedone with respect to mineralization and mobilization of biosolids phosphorus in soil.

Mammographic screening patterns in Sokoto, Northwestern Nigeria

Background: Screening mammography is a radiographic examination of the breast performed for early detection of breast cancer in asymptomatic women. The American College of Radiology recommends that women should have mammography at the age of 40 years and annually thereafter. However, those who are at increased risk of breast cancer should start screening mammography earlier. These include patients with a strong family history of breast cancer or those who had radiotherapy to the chest wall.Objective: This study is aimed at evaluating the mammographic outcomes among 77 Nigerian females who had screening mammographic breast examination. Materials and Methods: From December 2010 and November 2012, 77 females had routine screening mammography in the department with the general electric alpha­RT machine with model number MGF­101 (manufactured 2010). All the participants had to fill a mammographic form consisting of variables such as age, sex, occupation, family history ofbreast cancer, tribe, contraception, parity and caffeine consumption, history of surgical intervention (lumpectomy, biopsy, and/or mastectomy), previous mammography, and last childbirth. Mediolateral­oblique and cranial­caudal views were done for the breast examination though additional were occasionally employed. Results: Seventy­seven females had screening mammography. The minimum age recruited was 40 years. The mammographic outcome for those who had screening was normal in 51 (66.2%) and abnormal in 26 (33.8%) participants. The abnormal mammographic outcomes were architectural distortion in either or both breasts in 13 (16.9%) participants, masses in either or both breast in 11 (14.3%) participants, while isolated calcification in either or both breast among 2 (2.6%) participants. Two (18.2%) of the subjects with masses had associated macrocalcification. No masses with malignant features were seen. Conclusion: Screening mammography was found out to be useful in detecting various forms of breast pathologies which were mostly breast masses, calcifications, and architectural distortions. Screening mammography is, therefore,advised yearly and routinely for women age 40 years and above

Prevalence and outcome of hypoglycemia in children attending emergency pediatric unit of a specialist hospital in Nigeria

Background: Hypoglycemia is a common metabolic problem encountered in pediatric emergency admissions. The absence of clinical symptoms does not preclude the presence of hypoglycemia as presentation may vary from asymptomatic to central nervous system and cardiopulmonary disturbances. If untreated, hypoglycemia can result in permanent neurological damage or even death. Objectives: The objective of the study is to determine the prevalence, associated factors and outcome of hypoglycemia in pediatric emergency admissions at Ahmad Sani Yariman Bakura Specialist Hospital, Gusau, Nigeria. Materials and Methods: The study was a prospective cross­sectional study involving children aged 1 month­13 years. Blood glucose was determined at admission using Accu­Chek® Active Blood Glucose Meter, and hypoglycemia was defined as blood glucose levels <2.8 mmol/L (<50 mg/dL). Age of the patients, sex, interval of last meal, presenting complaints diagnoses were recorded. Results: A total of 154 children were studied.Thirty (19.5%) were infants and 71 (46.1%) were under­fives. Eighty­seven (56.5%) were males with male to female ratio of 1.3:1.The prevalence of hypoglycemia was 22.1%. The predominant disease conditions the children with hypoglycemia presented with were severe malaria, acute diarrheal disease, and sepsis. The prevalence of hypoglycemia was significantly higher among children whose last meal was 8 h and above before presentation (42.9%). Children who presented with hypoglycemia were significantly more likely to die (odds ratio [OR] =13.3; 95% confidence interval [CI] =4.6­38.7). Among those with hypoglycemia, males were significantly more likely to die (OR = 4.2, 95% CI = 1.0­18.0). Hypoglycemia was significantly associated with mortality in children with severe malaria and pneumonia (P = 0.04 and 0.01, respectively). Conclusion: The prevalence of hypoglycemia is still high in our emergency admissions. It is associated with significant mortality especially among male children and those presenting with severe malaria and pneumonia. We recommend that hypoglycemia sought for and promptly treated in children presenting to emergency to reduce mortality

Antibacterial properties of Persicaria minor (Huds.) ethanolic and aqueous-ethanolic leaf extracts.

Persicaria minor known as small water-pepper is used traditionally for the treatment of dandruffs and stomach indigestion. Therefore, this study was designed to evaluate the antibacterial activity of plant leaf material. 30% aqueous-ethanol and 100% aqueous were used for solvent extraction. Both extracts were evaluated for total protein and polysaccharide contents and results were compared. The extracts were then tested against four strains of bacteria; Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 11229, Staphylococcus aureus ATCC 6538and Pseudomonas aeruginosa ATCC 1544,at different concentrations using disc-diffusion and microplate dilution assays with penicillin being used as a positive control standard. Both extracts showed antibacterial activity against S. aureus, E. faecalis, and E. coli, respectively with aqueous-ethanolic extract being more potent. However, none of the extracts were active against P. aeruginosa. Results from this study truly illustrated high potential of P. minor leaves to be used topically as antibacterial agent for controlling of tested colony.
