Neutrophil To Lymphocyte Ratio As A Predictor Of Severity In Colorectal Adenocarcinoma.

BACKGROUND: Colorectal cancers are slowly developing cancers of which more than 95% are adenocarcinomas, beginning in the mucus-producing glands lining the colon and rectum. In Pakistan, colorectal carcinoma is ranked as the seventh most common malignancy in men and the ninth most common in women with a male to female ratio of 9 to 1. This study aimed at investigating Neutrophil to Lymphocyte Ratio (NLR) as a potential marker for predicting severity of disease in terms of tumour histological grade in patients with pre-operative colorectal adenocarcinoma. METHODS: Retrospective cross-sectional study design was adopted and this study was conducted at the Department of Pathology, Pakistan Institute of Medical Sciences Islamabad. Sixty patients of all age-groups and both genders, diagnosed as colorectal adenocarcinoma on histopathological examination of resected specimens, were selected by consecutive non-probability sampling. Separately, 60 healthy subjects, age and sex-matched, were selected as control. RESULTS: Results revealed that the most common age group was 41-60 years showing 29 cases (48%) followed by the age group 61-80 years with 17 cases (28%). The most common site was the rectum having 24 cases (40%) followed by the right hemicolon with 13 cases (21.7%). The mean of neutrophil to lymphocyte ratio rose in direct proportion to the grade of colorectal carcinoma, showing a mean value of 4.5 in well differentiated low grade carcinoma, 5.0 in moderately differentiated and 6.0 in high grade poorly differentiated carcinoma. All patients had higher total leukocyte count, higher absolute neutrophil count, higher total neutrophil percentage and higher NLR as compared to their normal healthy counterparts. CONCLUSIONS: It is concluded that the NLR is directly proportional to tumour grade so it can be used preoperatively to assess whether the tumour is advanced so that it can be dealt with accordingly. This ratio can also be used as an independent screening marker for colorectal carcinoma since it shows very low levels in normal colonic epithelium.

MRI Changes Among Patients Of Eclampsia And Preeclampsia With Associated Neurological Symptom Analysis.

BACKGROUND: Pregnancy poses some stress on normal homeostasis of the human body and brings changes in the body which predisposes the individual towards various pathological conditions as well. Objective: Objective of the study was to determine the magnetic resonance imaging (MRI) changes and clinical symptoms associated with these changes among patients of eclampsia and preeclampsia managed at tertiary care unit. It was a cross-sectional study, conducted at Gynaecology and obstetrics department Pak Emirates Military Hospital (PEMH) Rawalpindi. January to June 2019. METHODS: A total of 80 pregnant women who were diagnosed by consultant obstetrician for eclampsia or pre-eclampsia were included in the study. All the patients underwent Plain MRI brain including TIWI, T2WI, FLAIR, DWI, ADC, GRE and SWI sequences at radiology department of PEMH RWP. Positive MRI findings were defined as presence of cerebral oedema, infarction, cerebral venous sinus thrombosis and cerebral haemorrhage. Headache, seizures, altered mental status and visual problems were correlated with MRI changes among the target population. RESULTS: Out of 80 pregnant women with eclampsia or preeclampsia, 49 (61.2%) had no changes on MRI while 31 (38.8%) had significant changes on MRI. Cerebral oedema 12 (15%) was the most common MRI finding followed by cerebral haemorrhage 8 (10%). Mean age of participants was 36.33±2.238 years. With Pearson chi-square analysis, it was found that presence of seizures and altered mental state had statistically significant relationship with presence of MRI findings among the target population. CONCLUSIONS: MRI changes were a common finding among the patients of eclampsia or pre-eclampsia. Cerebral oedema was the commonest finding in our study. Patients with serious clinical symptoms like seizures and altered mental state had more chances of having MRI changes as compared to patients without the serious clinical symptoms.
