SUMMARY The rate of return to normal of the pylorus muscle in infantile hypertrophic pyloric stenosis was measured by ultrasound, using a simple pyloric volume calculation and a pyloric muscle index. The muscle hypertrophy took from two to 12 weeks to resolve.
Milk bolus obstruction of the neonatal bowel apparently related to the use of artificial powder milk, particularly full cream cows milk, was first recognised in the late 1960s. The syndrome almost disappeared with the use of highly modified cows milk formulae but has now re-emerged in the low birth weight population with the early use of high calorific feeds specifically designed for these infants. We describe four cases of obstruction and perforation of the bowel seen on our neonatal intensive care unit in 1 calendar year and discuss the possible aetiology of this condition.
Codeine substitute challenges to drug and substance abuse controls in Nigeria: Histopathology evaluations of Norvegicus rattus on lacatomtom is novel research that aimed to evaluate the Codeine substitute challenges to drugs and substance abuse; histopathology perspective and oxidative biomarkers evaluation of the tissues cum chemical pathology analysis of the serum of the control and intervened subjects. The experimental subjects were grouped into control, acute and chronic (T1, T2, and T3) respectively; the acute groups of the oral administration of lacatomtom mixture were given 0.01mg/g of lacatomtom for 14 days while the chronic were given for 42 days and periodically weighed and recorded; The Animals were sacrificed and the organs harvested following ethical procedures for animal killing. The blood and tissues of the harvested organs (blood, lungs, liver, and kidney) under investigation were subjected to chemical pathology analysis to assess the liver and kidney functions, then proceeded to histopathological examination using formalin fixed paraffin processed methods with both routine and special stains, liver, lungs and kidney homogenate were subjected to oxidative stress biomarkers test (MDA, SOD, Gpx, GSH and Catalase). Histopathology results first revealed a severe cellular injury in all the organs under study compare to the normal control; significance (p<0.5) elevation found among some enzymes AST, ALP ALT are also an indication of damaged liver, increase MDA and reduced SOD, Gpx, GSH and catalase correlate the histology results and biochemistry.
Introduction: Histological stains are biological dyes which colour tissue in order to aid optical differentiation of tissue component. Dyes are coloured substance which impact colour for material such as textile, cosmetic, food, drugs, rubber plastics, hair, fur and tissues. There are two types of dyes namely; natural dyes and synthetic dyes. Allium cepa is an imperative, evergreen plant, which belongs to the family Amaryllidaceace commonly called bulb onion. Aim: This research work aimed at evaluating the staining capability of onion extract as counter stain when haematoxylin was used as primary stain. Methods: Tissue blocks sections of liver and kidney organs were made from the Wistar rat. Serial sections labelled A to M were made from each block and stained with Harris haematoxylin. Section A was counterstained with eosin, as control. Different preparations of extracts of the onion skin were used to counter stain sections of kidney and liver tissues. Group B to Mwere kidney and liver tissues stained as follows: B, E, H and K (5% aqueous and ethanolic extract with ferric chloride, 5% aqueous and ethanolic extract with potassium aluminium alum, and 5% aqueous and ethanolic extract without mordant, for 10 and 20 minutes). C, D, F, G, I, J, L and M (5% aqueous and ethanolic extract with ferric chloride, 5% aqueous and ethanolic extract with potassium aluminium alum and 5% aqueous and ethanolic extract without mordant for 10 and 20 minutes). Results: The skin extract of Allium cepa stained the cytoplasm of cells and connective tissues in shades of reddish brown to yellowish brown. The study established the cytoplasmic counter-staining ability of the extract of Allium cepa. Conclusion: It is therefore suggested that onion skin extract solution can be substituted for eosin due to its domestic availability, ease of preparation and above all, its good cytoplasm contrast with the nuclear stain.
Vesicovaginal fistula (VVF) is a non-physiological epithelial fistulous tract between the bladder and the vagina, resulting in continuous urinary incontinence. VVF occurs most commonly after obstetrical and gynecological injury. This study is a descriptive cross-sectional study designed to carry out cytological evaluation of urine samples of vesicovaginal fistula patients in National Obstetrics Fistula Centre, Southeastern Nigeria. The voided and catheterized urine samples collected were stained using Papanicolaou and Diff-Quick staining techniques. A total number of 123 patients were involved in this study. The mean age of the patients was 36.66 (± 6.21) years. The patients were grouped according to age into 4 groups: 1 (0.8%) was ≤ 24 years, 59 (48.0%) were 25 to 34 years, 43 (35.0%) were 35 to 44 years and 20 (16.2%) were ≥ 45 years of age. The parity status of these cases was grand multipara 29 (23.6%), multipara 32 (37.4%), primipara 46 (37.4%) and nullipara 16 (13.0%). Majority of the patients 111 (90.2%) were from rural areas, 8 (6.5%) from urban areas and 4 (3.3%) were from semi-urban areas. According to marital status, 91 (74.0%) were married, 16 (13.0%) were widowed, 5 (4.1%) were single and 11 (8.9%) were divorced. According to the period the patients had lived with fistula, majority of the patients 94 (76.4%) had lived less than one year with this problem, while 29 (23.6%) had suffered from VVF for 1-5 years. Cytological evaluation of the urine smears showed that a total of 92 (74.8%) urine samples had normal findings. The rest of the 31 (25.2%) urine samples showed a variety of findings. Out of these 31 samples, 16 (51.6%) showed inflammatory aggregates suggestive of urinary tract inflammation, 3 (9.7%) showed decoy cells suggestive of Polyoma virus infection, 7 (22.6%) cases showed perinuclei halo suggestive of Trichomonas vaginalis infection, 3 (9.7%) showed oval fat bodies suggestive of possible nephrotic syndrome, 8(25.8%) cases showed koilocytes, indicative of Human papilloma virus infections. Cases that showed presence of haematuria were 7 (22.6%). There was no case of tumor cells detected in all the urine samples examined. From the outcome of this study, it is important to take special note of the presence of the viral carcinogens: Polyoma virus and Human papilloma virus, since in theory and as reported in few case reports, malignancy of the urinary tract can lead to formation of vesicovaginal fistula.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
