Neuroendocrine markers and sustentacular cell count in benign and malignant pheochromocytomas – a comparative study

Abstract Purpose This study aims to detect and compare the severity and pattern of dry eye occurrence after phacoemulsification and extra capsular cataract extraction surgeries. Methods Twenty eyes of twenty patients in two groups, ten eyes planned for Phacoemulsification(phaco) and ten eyes planned for Extra Capsular Cataract Extraction (ECCE) enrolled in a prospective comparative study. All patients underwent full history taking and full ophthalmological clinical evaluation including (tear film meniscus height, Schirmer 1 test, tear break up time). Evaluations will be done one week before cataract surgery then three and six weeks after the surgery.Also, goblet cell count is measured twice, before and 6 weeks after the operation. Results After both Phaco, andECCE, the changes between means of pre-operative, 3 weeks and 6 weeks visits were significant in tear film meniscus height (p = 0.01) and were insignificant in both Schirmer 1 and tear break up time (p > 0.05). There was a significant deterioration after 3 weeks of surgery in tear film meniscus height followed by significant increase between 3rd and 6th weeks post-operative measurements (p = 0.01). There was a significant difference between the 2 groups in the total change of Schirmer 1 and tear break up time between the6th weeks and the pre-operative measure with more deterioration in group 2. There was no significant difference between the 2 groups in tear film meniscus height 6 weeks post operation.The deterioration in goblet cell count was significantly worse in the ECCE group (mean difference of -22.1±8.5 and was -7.5±5.1 in the phaco group), (p = 0.0005). Conclusions Phacoemulsification surgery may aggravate the signs and symptoms of dry eye and affect dry eye test values in patients in short-term but less than ECCE.

Domestic Rabbits

Comparative study of single infections of domestic rabbits (Oryctolagus cuniculus) with Nigerian isolates of Trypanosoma brucei (Gboko strain), and Trypanosoma congolesense (Binchi strain) was carried out in the laboratory for clinical and haematological effects. Eighteen rabbits of 10-14 weeks old weighing between 600- 1200 grams were used for the study. The rabbits of both sexes were randomly selected and divided into groups. The level of infection was studied by determining red blood cell (RBC) count, haemoglobin estimation, total and differential white blood cell (WBC) count, changes in body weight, mortality, rectal temperature changes and other clinical signs of trypanosomiasis. There was significant reduction (P<0.001) in the total red blood cell counts and haemoglobin level in the rabbits when compared to the control rabbits with the effect being more pronounced in those rabbits infected with T. congolense. The white blood cell count was also highest in those rabbits infected with T. congolense. Both parasites produced similar clinical symptoms which included weight loss, unthriftiness, anorexia, fever, paleness of mucous membrane, and oedema of the facial region. One death was recorded in each of the infected group. Possible reasons for the significant differences in the total red blood cell count, haemoglobin level, and total whitre blood cell count are discussed.

BACKGROUND The main attributes of cornea which makes it optically important is its ability to maintain its dehydrated state. This corneal dehydration can be achieved and maintained by various factors among which corneal endothelial cell count and morphology play a significant role. Corneal attributes considered in this study i.e. the corneal endothelial cell count and central corneal thickness are extremely variable, and changes are seen even with smaller changes in anterior segment or overall structural changes in eyes. We wanted to compare central corneal thickness in emmetropia and axial myopia and compare corneal endothelial cell count in emmetropia and axial myopia. METHODS The sample size was decided taking into consideration various prevalence studies. The patients were consecutively recruited for the study considering the inclusion and exclusion criteria. The subjects were divided into two groups emmetropia and axial myopia and were differentiated on the basis of the axial lengths. Specular microscopy was performed for the subjects and corneal endothelial cell count, morphology and central corneal thickness were measured, and comparative study was performed. RESULTS This study of 80 eyes shows us that the difference between mean the corneal endothelial cell count between emmetrope (2812.80 cells / mm2) and axial myopes (2653 cells / mm2) is statistically significant where p was < 0.05 while the mean central corneal thickness measurements didn’t show statistically significant change between emmetrope (490.05 microns) and axial myope. (489.37 microns). CONCLUSIONS Axial length has an indirect correlation with the corneal endothelial cell count which is statistically significant. While significant correlation between the central corneal thickness and axial length cannot be established in this study.
