Prevalence of Thyroid Dysfunction in Type 2 Diabetes Mellitus

The level of thyroid hormones is often changed in uncontrolled diabetic patients. Screening for Thyroid dysfunction (TD) among patients with Type 2 Diabetes mellitus (T2DM) should be performed considering the increased prevalence of thyroid disorders. This cross-sectional comparative study was conducted in outpatient department of Endocrinology and Medicine, Mymensingh Medical College Hospital, Mymensingh (MMCH) from 1st March 2020 to 30th August 2021. One hundred (100) patients with type 2 diabetes along with 100 (hundred) non-diabetic controls of same age group were enrolled in the study. After taking clinical data, patients were investigated to estimate Fasting plasma glucose (FPG), serum free tri-iodothyronine (FT3), free thyroxin (FT4) and thyroid stimulating hormone (TSH) level to see thyroid dysfunction. Patients were selected with purposive sampling. Thyroid dysfunction was found to be more in T2DM (15.0%) in comparison with non-diabetic controls (5.0%) and this difference was statistically significant (p=0.018). In both diabetic and non-diabetic groups, subclinical hypothyroidism and hypothyroidism were the most common thyroid dysfunction. Thyroid dysfunction was found more in 40-60 years that suggests the prevalence of thyroid dysfunction are increasing in diabetic patients with advancing age. Thyroid dysfunction was found more among overweight and obese patient in both groups. Mean BMI was found higher among diabetic patient with thyroid dysfunction. Logistic regression showed significant association of Thyroid dysfunction with age >50 years and high FPG level. We found thyroid dysfunction was more prevalent in patients with T2DM than non-diabetics. So, screening for thyroid dysfunction among type 2 diabetic patients by estimating Serum TSH, FT4 level should be performed.

A two-generational reproductive study to assess the effects of Juglans regia on reproductive developments in the male and female rats

Environmental pollutants and lifestyle severely threaten human and animal health, leading to disturbances of various functions, including infertility. So, exploring a safe treatment that could effectively reverse infertility remains a challenge. The current study was intended to explore the fertility-enhancing effect of Juglans Regia oil in two successive generations of rats; F0 and F1. J. Regia oil was initially tested for in vitro antioxidant assay via ROS and DPPH, followed by in vivo toxicity testing. In the fertility assessment, eighteen pairs of male and female rats (n=36, 1:1, F0 generation) were divided into three groups and dosed with 1 mL/kg and 2 mL/kg daily of J. Regia oil and saline, respectively, up to pre-cohabitation, cohabitation, gestation and lactation periods. The reproductive performance, including body weight, live birth index, fertility index, and litter size, was assessed. Hormonal and antioxidant markers of F1 generations were assessed with the histopathological evaluation of male and female organs. The oil of J. Regia showed great antioxidant potential (P < 0.05) in DPPH (1,1-diphenyl-2-picrylhydrazyl) and ROS (Reactive Oxygen Species) methods (P<0.05). The continued exposure of the F0 and F1 generations to J. Regia oil did not affect body weight, fertility index, litter size, and survival index. We have found pronounced fertility outcomes in both genders of F0 and F1 generations with J. Regia 2 mL/kg/day in comparison to the control. Results showed that J. Regia significantly increased (P < 0.05) luteinizing hormone (LH), plasma testosterone, follicular stimulating hormone (FSH), glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities in both generations. Histology of both generations reveals improved spermatogenesis and folliculogenesis with enhanced architecture. Altogether, the present results suggest that J. Regia improved fertility in both male and female rats by improving hormonal activities and oxidative stress.

Association of Chest Pain with Rate Pressure Product and ST-segment Changes after Sub Arachnoid Block in Caesarean Section

When healthy women undergo caesarean section (CS) under sub arachnoid anaesthesia, transient electrocardiographic changes, such as ST-segment depression and T-wave abnormalities, are observed. During an elective caesarean section under sub arachnoid anaesthesia, about one-third of healthy parturient experience chest pain and ECG changes suggestive of myocardial ischemia. To assess the ST-segment and Rate Pressure Product changes with chest pain in patients with elective caesarean section under subarachnoid block. The Department of Anesthesia, Analgesia and Intensive Care Medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh was the site of this prospective observational study. The study included 86 healthy women between the ages of 20 and 35 who needed an elective caesarean section under a single shot sub arachnoid block and who visited the Department of Anesthesia, Analgesia, and Intensive Care Medicine at BSMMU in Shahbagh, Dhaka from January 2019 to June 2019. In comparison to the no chest pain group, ST-segment changes among the chest pain group at delivery, 5 minute, 10 minute after delivery and at the end of the surgery were highly significant (p=0.001). Comparatively, Rate Pressure Product changes were found to be significantly higher in the group with chest pain than in the group without chest pain (p=0.001). It is concluded that there is a substantial association of chest pain with rate pressure product and ST-segment changes after subarachroid block in caesarean section.

Complications of Therapeutic Plasma Exchange in pediatric patients: An experience at a tertiary care hospital

Objective

To find the incidence of various complications of therapeutic plasma exchange (TPE) in ICU admitted children and to determine their association with age, gender, blood group and diagnosis of the patients.

Methods

In this observational study, data of 24 patients who underwent 125 sessions of TPE was collected from the Pediatric Intensive care unit (PICU) and Hematology department of The Children's Hospital, Lahore from December 2020 to November 2021. Age, gender, blood group, indications and complications observed during and after the TPE procedure were documented on a pre-designed proforma. The data was analyzed by using SPSS version 23. Quantitative variables were presented in the form of mean and standard deviation. Qualitative variables like gender, blood groups, indications and complications of plasmapheresis were presented as frequency and percentage. Chi square test was applied for comparison of variables.

Results

Among the 24 patients, 45.8% were of age group five to ten years with mean age of 7.58 years± 2.04 years and male to female ratio of 0.84:1. Guillain-Barré syndrome (GBS) and Neuromyelitis Optica spectrum disorder (NMO-SD) were the most prevalent among the patients who underwent TPE. Most common complication was hypotension (44.9%), others were febrile reactions (11.6%), unstable vital signs (14.5%) and allergic reactions (24.6%). Blood group, clinical condition and diagnosis of the patient showed significant association with the incidence of TPE related complications.

Conclusion

The majority of problems caused by TPE are considered to be minor. Sudden fall in blood pressure, pruritus, urticarial rash and fever are the common adverse consequences among pediatric patients. Blood group and diagnosis of the patient can determine the development of such complications during plasmapheresis procedure.

Magnetic Resonance Imaging Evaluation of Common Spinal Intramedullary Tumours: Ependymoma and Astrocytoma

This cross-sectional study was carried out in the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from January 2015 to June 2016 in collaboration with Department of Neurosurgery and Department of Pathology of same hospital, to assess MRI findings of common IMSCTs and to find out the validity of MRI in the diagnosis of spinal ependymoma and astrocytoma, thereby differentiating these two common intramedullary entities. For this purpose, 40 patients aged from 15 to 60 years, who were diagnosed or suspected cases of having intramedullary spinal cord tumours were enrolled. These patients underwent preoperative MRI for evaluation of the spinal cord tumours during the study period in department of Radiology and Imaging. Also, patients were diagnosed by MRI as having IMSCTs incidentally was included. All of them were followed by histopathological examination of the same lesions after surgery. Among these 40 patients after exclusion for valid reason 28 cases were included as study population. MR images were obtained on a 1.5 Tesla (Avanto Magnatom, Siemens) unit with a spine surface coil. MRI findings were compared with histopathology after surgery keeping histopathology as gold standard. Out of 28 clinically and MRI diagnosed IMSCTs cases, 19 cases of ependymoma, 8 cases of astrocytoma and one diagnosed as hemangioblastoma by MRI. The mean age was 34.11±9.55 years, ranging from 15 to 56 years for ependymoma, 26.88±8.08 years ranging from 16 to 44 years for astrocytoma. Highest incidence (47.4%) was in between 31 to 40 years for ependymoma, 50.0% were in between 21-30 for Astrocytoma. On MRI majority 12(63.2%) of the cord ependymomas and majority 5(62.5%) of astrocytomas were in cervical region. While considering axial location ependymomas are mostly 17(89.5%) central and astrocytomas 5(62.5%) are eccentric in location. It was observed that out of 19 cases of ependymoma more than half 10(52.6%) had elongated shape, 12(63.1%) had well defined margin. Associated syringohydromyelia was present in 16(84.2%) cases. On T1WI 11(57.9%) and 8(42.1%) cases were iso and hypo respectively. On T2WI 14(73.7%) cases were hyper intense. After Gd-DTPA in most cases, 13(68.4%) cases showed diffuse enhancement. Noticeable and sizeable solid component observed among 13(68.4%) of the cases. Hemorrhage with cap sign was found in more than one third 7(36.8%) cases. Out of 8 cases of astrocytomas 4(50.0%) had lobulated shape, ill-defined margin 5(62.5%). T1WI: Iso 5(62.5%), hypo 3(37.5%), T2WI: hyper 5(62.5%), After Gd-DTPA: focal and heterogenous enhancement 3(37.5%) and rim enhancement 4(50.0%). Component: mixed 4(50.0%), cystic 3(37.5%) and solid 1(12.5%). Hemorrhage without cap sign 2(25.0%), associated syringohydromyelia 1(12.5%). In the case of evaluation of intramedullary ependymoma sensitivity of MRI in the present series is 94.44%, specificity 80.0%, Positive predictive value (PPV) 89.5%, Negative predictive value (NPV) 88.9% and accuracy 89.28%. In case of MRI evaluation of intramedullary astrocytoma sensitivity of MRI in the present study is 85.71%, specificity 90.47%, PPV 75%, NPV 95% and accuracy 89.2%. Thus present study shows MRI is a sensitive and effective noninvasive imaging modality in diagnosing common intramedullary spinal cord tumours.

Dexmedetomidine as an Adjuvant to Bupivacaine in Caudal Analgesia in Children Undergoing Infra-Umbilical Surgery

When performing infra-umbilical procedures, caudal epidural analgesia with bupivacaine is frequently used to provide both intra- and post-operative analgesia. Dexmedetomidine, an alpha 2 agonistsare extensively used in neuraxial blocks and peripheral nerve blocks to prolong the action of bupivacaine. To find out the effects of dexmedetomidine as an adjuvant to bupivacaine for caudal analgesia in children undergoing infra-umbilical surgery. This was a randomized, controlled double-blinded prospective observational study and was performed from July 2019 to December 2019. A total of 60 (Sixty) patients with different infra-umbilical surgical problems underwent different procedure under caudal anaesthesia in different operation theatre in Bangabandhu Sheikh Mujib Medical University, Dhaka were enrolled in this study. Elaborate personal history, meticulous clinical examinations and relevant laboratory investigations was done. Post-operative adverse effects also were monitored. All information from history of illness, clinical, laboratory findings, duration of analgesia and post-operative adverse effects were recorded in a preformed data sheet (Appendix-I) and statistical analysis was done by SPSS 22.0. Mean age of the children in Group A (dexmedetomidine + bupivacaine) was 5.50±2.61 years and in Group B (bupivacaine) was 5.66±2.75. Mean weight of the children in Group A was 19.22±8.58 kg and in Group B was 19.70±8.94 kg in this study. Mean duration of anaesthesia was 27.5±6.5 minute in Group A and 28.5±5.5 minute in Group B. The mean duration of analgesia was 4.32±0.54 hours for Group A and 2.12±0.32 hours in Group B. In Group A, 46.7% patients required 1 and 3.3% required 2 rescue analgesic but in Group B, 43.3% patients required single rescue analgesic and 33.3% required two rescue analgesics (p<0.05). In Group A, 6.7% patients had nausea/ vomiting and in Group B, 16.7% patients had nausea/ vomiting (p>0.05). It can be concluded that dexmedetomidine with bupivacaine for caudal analgesia in infra-umbilical surgery significantly prolongs the duration of postoperative analgesia when compared to bupivacaine alone without any side-effects.

Antenatal and postnatal factors associated with neonatal death in the Indian subcontinent: a multilevel analysis

OBJECTIVES

This study aimed to identify significant antenatal and postnatal factors associated with neonatal death at 2-7 days and at 2-28 days in the Indian subcontinent. Results from this study may help guide strategies to improve antenatal and postnatal care services and reduce neonatal mortality.

STUDY DESIGN

Nationally representative recent Demographic and Health Survey data sets from five countries, including Bangladesh, India, Pakistan, Maldives and Nepal, were used.

METHODS

Survey-weighted univariate distributions were used for study population characteristics and bivariate distributions, along with the chi-squared test for unadjusted associations. Finally, multilevel logistic regression models were performed to determine the association of antenatal care (ANC) and postnatal care (PNC) factors with neonatal deaths.

RESULTS

Among 200,499 live births, the highest neonatal death rate was observed in Pakistan, followed by Bangladesh, whereas the lowest rate was in Nepal. After adjusting for sociodemographic and maternal control variables, the multilevel analysis showed a significantly lower likelihood of neonatal death at 2-7 days and 2-28 days with ANC visits <12 weeks' gestation, at least four ANC visits during pregnancy, PNC visits within the first week after birth and breastfeeding. Delivery at home by a skilled birth attendant compared to unskilled birth attendant was significantly associated with lower neonatal death at 2-7 days. Multifoetal gestation was significantly associated with higher neonatal death at 2-7 days and at 2-28 days.

CONCLUSIONS

The findings suggest that strengthening ANC and PNC services will improve newborn health in the Indian subcontinent and decrease neonatal mortality.

Combined Effects of Nickel and Arsenic on Growth and Mineral Nutrients Accumulation in Kalmi (Ipomoea Aquatica), Red Amaranth (Amaranthus SP.) And Spinach (Spinacia Oleracea L.) And Nutrient Release Pattern In Soil at Different Days of Incubation

Arsenic (As) is a broadly distributed toxic metalloid that accumulates in the environment through natural and anthropogenic sources. Numerous techniques were evolved for arsenic remediation from water including adsorption, flocculation, ion exchange and reverse osmosis. Due to the excessive affinity between iron and inorganic arsenic species, iron-based adsorption is an emerging technique for the remediation of arsenic-contaminated water and soil. Whereas iron (Fe) and nickel (Ni) belong to the same chemical group (VIIIB) in the periodic table, it is expected to get similar interaction of Ni with As. An in vitro incubation study and pot experiment were conducted to evaluate the effect of Nickel on mineral release patterns in soil and growth yield of kalmi (Ipomoea aquatica), red amaranth (Amaranthus sp.) and Spinach (Spinacia oleracea L.). Nickel was applied as different doses of Nickel of 10, 40 and 160 mg/kg respectively where As was applied with irrigation water at the rates of 1 mg/L and incubated at field moisture condition for 10, 20 and 30 days individually in different pots. Total organic carbon (C), total nitrogen (N), phosphorus (P), sulfur (S), potassium (K) and 0.1N HCl extractable arsenic (As), iron (Fe) contents were determined at 10, 20 and 30 days of incubation. The pot experiment was carried out in triplicates for 45 days till the plants were grown to maturity. The growth performance of plants and the remedial effect of Ni on As toxicity in soil and plant was examined. Nickel showed a significant impact on fresh and dry yield of three plants and an antagonistic relationship between Ni and As was also observed i.e., Ni in soil was found to lessen the availability of As in soil likewise its accumulation in plants.

Diagnostic Accuracy of Magnetic Resonance Imaging in Evaluation of Anterior Cruciate Ligament Tear

The anterior cruciate ligament (ACL) is the most generally injured one of the major knee ligaments. These injuries plague both athletes and non-athletes. This cross-sectional and comprehensive study was conducted in the Department of Radiology and Imaging collaborating with Department of Orthopedics of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, completed from January 2014 to December 2015. The study evaluated the role of MRI in the diagnosis of anterior cruciate ligament injury of knee joint, keeping Arthroscopy as standard, compared the MRI and arthroscopic findings to determine accuracy, sensitivity and predictivity of MRI in the diagnosis of ACL injury in knee joint. For this purpose, a total of 50 patients having clinical suspicion of ACL injury in knee joint were enrolled in this study to perform MRI and Arthroscopy. MRI was done in all these patients. Clinically suspected but MRI diagnosed as no ACL injury, patients who were not willing to undergo arthroscopy examination and patient who were not fit for arthroscopy were excluded from the study. More than half (52.0%) of the patients were in 3rd decade and male to female ratio was 3.5:1. Less than one fourth (24.0%) of the patients were service holder. Forty two percent patients had duration of suffering for 2 weeks. Most 49(98.2%) patients had history of trauma, 45(90.0%) had pain in Knee joint, 24(48.0%) had difficulty in walking, 19(38.0%) had swelling in Knee joint and 13(26.0%) had restricted range of motion. Anterior drawer test was 37(74.0%) and Lachman test 16(32.0%). Loss of normal contour of ACL was found in 50.0%. Signal change of ACL in PD and T2W1 was found 42(84.0%) patients, and thickened ACL in 33(66.0%) patients. In MRI diagnosis tear was present in 80.0% of the patients. ACL tear diagnosed by MRI among the patients, 20(40.0%) had partial tear and 20(40.0%) had complete tear. In arthroscopy diagnosis 38(76.0%) had tear present. ACL tear diagnosed by arthroscopy of the patients 15(30.0%) had partial tear and 23(46.0%) had complete tear. Majority 20(40.0%) patients had medial meniscus injury, 15(30.0%) had lateral meniscus injury, 11(22.0%) had PCL injury, 4(8.0%) had lateral co-lateral ligament injury and 2(4.0%) had medial co-lateral ligament injury. In MRI diagnosis of anterior cruciate ligament tear, 37 cases were true positive, three cases false positive, one case false negative and nine cases was true negative. The validity of MRI diagnosis evaluation for anterior cruciate ligament tear was 97.4% sensitivity, 75.0% specificity, 92.0% accuracy, 92.5% positive predictive values and 90.0% negative predictive values.

Clinical Profile and Immediate Outcome of Pyogenic Meningitis in Children

Meningitis literally means inflammation of the meninges. It is mostly caused by bacteria, virus, fungus and protozoa and pyogenic meningitis constitutes a serious neurological disorder associated with significant morbidity and mortality in developing countries. This study was carried out to evaluate the clinical presentation and immediate outcome of pyogenic meningitis in children. This was a prospective observational study and conducted at department of Paeditrics in Cumilla Medical College Hospital, Cumilla, Bangladesh from July 2014 to June 2015. Total 50 children were diagnosed as pyogenic meningitis fulfilling the inclusion criteria was included in this study. Cases were enrolled purposively. Immediately after admission through history and clinical examination, complete blood count, random blood sugar, Cerebrospinal fluid (CSF) examination and blood culture was done in all patients. For statistical analysis chi-square test was done and significance of analysis was made when p value <0.05. This study includes patients aged between 2 months to 12 years and male female ratio was 1.5:1. Several risk factors like male sex (60.0%), age below one year (42.0%), Protein energy malnutrition (PEM) (30.0%), not exclusively breastfed (44.0%) were identified. Common presenting complaints were fever (100.0%), convulsion (96.0%), altered consciousness (42.0%) and vomiting (38.0%). Common physical signs were neck rigidity (56.0%), Kernig's sign (26.0%) and bulged fontanelle (34.0%). CSF was hazy in 54.0%, clear in 38.0% and turbid in 08.0% cases, CSF protein was more than 100mg/dl in 90.0% of the cases and glucose was less than 40mg/dl in most of the cases (94.0%). Streptococcus Pneumoniae (49.0%) followed by Neisseria Meningitidis (38.0%) were the two most commonly isolated organism responsible for pyogenic meningitis. Mortality rate during hospital stay was 18.0% and complications developed in 18.0% of cases. To avoid maltreatment in our resource limited setting due to failure of identifying organism, this study might help to administer appropriate antibiotics against organism and to reduce morbidity and mortality in meningitis. This study revealed less mortality rate in our country than neighbors and severe malnutrition important risk factors for the burden of pyogenic meningitis. It requires large scale multicentre studies to establish the whole scenario of Bangladesh.

Evaluation of Liver Function Tests in β-Thalassemia Major Children

Thalassemia is the most prevalent single gene defect in human beings worldwide. Repeated blood transfusions along with chelation therapy are mainstay of treatment in thalassemia patients. However these recurrent blood transfusions result in iron overload which along with chelation therapy causes deterioration of liver function. Aim of the study was to evaluate the liver function tests in β-thalassemia major patients. This cross sectional study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh from January 2017 to December 2017. In this study, 50 diagnosed patients of β Thalassemia major (Group A) and 50 apparently healthy children (Group B) of both sexes were selected from the department of Paediatrics, Dhaka medical college. The study parameters were serum ferritin, bilirubin, AST, ALT, ALP. The results were compared statistically between groups. Serum ferritin level (mean±SD) in thalassemic major patients in Group A (890±446.38 microgram/L) which is significantly higher above normal level. Serum bilirubin in Group A (3.27±2.62 mg/dl) and in Group B (0.48±0.24 mg/dl), Serum ALT in Group A (53.06±34.0 U/L) and in Group B (16.70±4.81 U/L), AST in Group A (84.56±33.54 U/L) and in Group B (11.60±2.72 U/L) and ALP levels in Group A (422.42±226.99 IU/L) and in Group B (221.86±80.54 IU/L). All the values were significantly higher (p<0.001) in β-thalassemia patient than that of normal children. This study concludes that liver function parameters are significantly higher in β thalassemia major patients. So routine evaluation of liver function tests may be advocated for thalassemic patients to predict early onset of hepatic dysfunction.

The prevalence, risk factors analysis and evaluation of two diagnostic techniques for the detection of Cryptosporidium infection in diarrheic sheep from Pakistan

Background

Cryptosporidium spp. is recognized as an opportunistic zoonotic parasite that infects humans as well as wild and domestic animals. This enteric protozoan is a major cause of diarrhea in humans and animals and often result in death due to severe dehydration. The present study was designed to investigate the prevalence, identification of various risk factors and evaluation of sensitivity of the two diagnostic techniques for rapid and correct detection of Cryptosporidium infection in diarrheic sheep in Pakistan.

Methods

A total of 360 fecal samples were collected and processed for detection of Cryptosporidium infection after proper preservation. These samples were properly stained with modified Ziehl-Neelsen acid staining and then examined under simple microscope at 100x magnification for confirmation of Cryptosporidium oocysts. The same samples were again processed through simple PCR for confirmation of the Cryptosporidium spp.

Results

The age wise prevalence was detected through simple microscopy and PCR. We found highest prevalence at the age of ≤1 year followed by 1–2 years of age while the lowest prevalence was recorded at the age of ≥ 2–3 years of sheep and found significant difference between different ages (P<0.05). The sex wise prevalence showed the highest prevalence in male (♂) animals detected compared to female (♀). The overall prevalence was detected 27.08% and 18.80% through PCR and simple microscopy, respectively, and significant difference between two diagnostic techniques were observed (P<0.05). Considering the seasonality, the highest prevalence was recorded through simple microscopy in autumn, summer, and spring, while the lowest in winter. These results were confirmed through PCR.

Conclusion

It was concluded that molecular detection is the most efficient, specific and sensitive technique for detection of Cryptosporidium infection than simple microscopy. Moreover sheep is the major potential source of infection to other wild and domestic animals including humans.

Age Related Changes in the Purkinje Cells in Human Cerebellar Cortex in Bangladeshi People

This study was done to see the changes in the number of Purkinje cells per square mm in different age groups of Bangladeshi people. This cross-sectional descriptive type of study was done on total 40 postmortem human cerebellums, in the Department of Anatomy, Mymensingh Medical College, Bangladesh from July 2016 to June 2017. The specimens were collected from morgue in the department of Forensic Medicine, Mymensingh Medical College, by purposive sampling technique. All the specimens were grouped into four categories: Group A (20 to 29 years), Group B (30 to 39 years), Group C (40 to 49 years) and Group D (50 to 59 years). Paraffin blocks of cerebellum were cut at 4-5μm thickness and stained with routine "Haematoxylin and Eosin" (H & E) stain. Estimation of number of Purkinje cell was done by using the counting circle and examined under the light microscope. In the present study, the mean±SD number of Purkinje cell was found 128.67±25.15 per sq mm in Group A, 136.53±34.45 in Group B per sq mm, 135.55±29.44 per sq mm in Group C, 127.69±35.31 per sq mm in Group D.

Number and Diameter of White Pulp of Spleen in Different Age and Sex Groups of Bangladeshi People

Spleen is a haemo-lymph organ and belongs to the reticuloendothelial system of human body, develops from mesodermal proliferation between the two leaves of dorsal mesogastrium. The microscopic structure of spleen is variable depending on the developmental stage of the organ, and the age and immune status of the individual. In our country, we depend on foreign data which came from the subjects of different races and from the individuals under different geographic conditions. So the study was carried out to minimize the dependency on foreign standards and to identify the diameter of white pulp in different age and sex of the Bangladeshi individuals with a view to establish local data bank related to spleen of Bangladeshi people. This cross-sectional descriptive study was performed on 65 postmortem human spleens (34 of male and 31 of female) to find out the number and diameter of white pulp of spleen of Bangladeshi people by purposive sampling technique. And done in Autopsy laboratory of the Department of Forensic Medicine of Mymensingh Medical College, Bangladesh from 16th October 2016 to 15th January 2017. The samples were divided into three age groups including Group A (5-20 years), Group B (21-40 years) and Group C (41-60 years). Dissection was performed according to standard autopsy techniques. For statistical analysis, unpaired student 't' test was done. The mean±SD number of white pulp of male spleen was greater than female spleen in Group A, B and C but mean±SD diameter of white pulp of female spleen was found greater than male spleen in all groups. Comparison of number of white pulp between sexes showed that statistically there was no significant difference within all the age groups at p>0.05 level. No age change was evident in diameter of white pulp but in between sexes, diameter is greater in females than males. Mean difference of diameter of white pulp between sexes showed no significant difference within the age groups at p>0.05.

706 IMPROVING PRESCRIPTION OF PARKINSON’S DISEASE MEDICATIONS FOR PATIENTS ON ELDERLY CARE WARDS AT ROYAL STOKE UNIVERSITY HOSPITAL

Introduction

Patients with Parkinson’s disease (PD) are commonly admitted into hospital with various acute medical conditions. Inaccurate prescription can result in adverse effects, increased hospital stay, and increased morbidity and mortality. We present a QIP conducted to improve PD medication prescription pattern among doctors and medication delivery from the nursing staff.

Method

In PDSA 1, we conducted a survey among doctors and nurses to assess their initial knowledge on PD medications. A baseline review of PD prescriptions on our Frail Elderly Assessment Unit (FEAU) was conducted. Our interventions include Introduction: of PD medication alert sticker attached to drug charts and recorded drug chart when they are taken off the wards. In PDSA 2, repeat survey was carried on Elderly care wards. We also reviewed PD prescriptions over a 2-week period on Elderly care wards.

Results

During the surveys, there were 55 respondents in PDSA 1 and 51 respondents in PDSA 2. The percentage of those who feel PD medications are critical medications remain similar in both cycles (98%). There was an improvement in the awareness of PD stickers from 44% to 83%. Those who feel PD alert stickers are appropriate improved from 93% to 100%. Respondents who chose all included appropriate PD medication sources for improving prescription pattern improved from 38% to 62%. There were 8 prescriptions during PDSA 1 and 21 prescriptions during PDSA 2. The use of PD stickers improved from 0% to 76%. The numbers of PD medications prescribed appropriately improved from 50% to 65%.

Conclusion

An improvement in prescription pattern was demonstrated, as we hope to improve patient safety and increase awareness across the trust. Our recommendations include use of PD medication alert sticker and recorded drug chart. We discussed our plans in Medicine Governance meeting, departmental newsletter, and presented in departmental audit meeting.

Abnormal fractional flow reserve and non-hyperaemic pressure ratios in patients with severe aortic stenosis and non-obstructive coronary artery disease

Background

Fractional flow reserve (FFR) and non-hyperaemic pressure ratios (NHPRs) are well-validated tools that assess the physiological significance of coronary artery disease (CAD). Low coronary lumen to myocardial mass (V/M) ratio on CT is associated with lower FFR/NHPRs and predisposes towards ischaemia in CAD. Whilst CAD and aortic stenosis (AS) frequently co-exist, patients report angina despite obstructive disease.

Purpose

We therefore sought to study the interrelationship between V/M and invasive pressure indices in patients with severe AS.

Methods

35 patients with severe AS were prospectively recruited as part of CAST-FFR study. Patients underwent CT coronary angiography and invasive pressure-wire assessment. All pressure-indices were assessed in the left anterior descending artery (LAD). Data was extracted to calculate FFR, iFR, diastolic pressure ratios (DPR and dPR) and Diastolic Hyperaemia-free Ratio (DFR). Patient-specific V/M were extracted off-site by independent core lab.

Results

Mean age was 75±7.5 years, median V/M ratio was 20.7 and mean aortic gradient and DI were 44.3±11.6mmHg and 0.23±0.4 respectively. 79% of patients had CADRADs score of &lt;2. There were moderate positive correlations between FFR/NHPRs and V/M, including FFR (r=0.60), PdPa (r=0.48), iFR (r=0.59), DPR (r=0.59), dPR (r=0.63), DFR (r=0.67), (all p&lt;0.005). In patients with positive pressure assessments, 69% (FFR), 71% (iFR), 70% (DPR) and 65% (DFR) had CADRADs score &lt;2. In severe AS, lower V/M was associated with lower pressure-indices (FFR 0.75 vs 0.86, iFR 0.79 vs 0.92, DFR 0.80 vs 0.91, all p&lt;0.005), leading to high rates of positive physiologic assessment (FFR 88%, PdPa 72%, iFR 67%, DPR 78%, DFR 74%).

Conclusion

Patients with severe AS exhibit high rates of abnormal FFR and NHPR values, despite having no obstructive CAD. Their propensity for having abnormal physiological results is, in part, influenced by coronary volume to mass ratio. These results are important for clinicians considering using invasive physiological tools to guide revascularisation decisions in patients with severe AS.

Evaluation of biological and chemical additives on microbial community, fermentation characteristics, aerobic stability, and in vitro gas production of SuMu No. 2 elephant grass

BACKGROUND

The study was conducted to evaluate the effects of biological and chemical additives on microbial community, fermentation characteristics, aerobic stability, and in vitro gas production of SuMu No. 2 elephant grass.

RESULTS

Aerobic bacteria and yeast were not affected on days 5 and 7 but were significantly (P < 0.224) reduced on days 14, 30, and 60, whereas lactic acid and lactic acid bacteria were significantly (P > 0.001) higher in all ensiling days within all treatment groups. During the ensiling days, the pH, acetic acid, butyric acid, and yeast were decreased in all treatment groups, whereas the Lactobacillus plantarum group and L. plantarum + natamycin group were highly significantly (P > 0.001) decreased. During air exposure, the water-soluble carbohydrates, ammonia nitrogen, lactic acid, and acetic acid were not affected on days 1-4, whereas pH and aerobic bacteria (were significantly (P < 0.05) increased on days 2-4. The addition of Lactobacillus plantarum and natamycin increased the gas production, in vitro dry matter digestibility, and in vitro neutral detergent fiber of SuMu No. 2 elephant grass silages.

CONCLUSIONS

The addition of biological and chemical additives, such as L. plantrum alone and the combination with natamycin, affected the undesirable microbial community, fermentation characteristics, aerobic stability, and in vitro gas of SuMu No. 2 elephant grass. © 2021 Society of Chemical Industry.

Successful Outcome Following Hysteroscopic Septoplasty in a Woman with Seven Consecutive Pregnancy Losses

Anomalies of the reproductive tract are common and present in about 3%–5% of the general population and in about 3% of infertile women. In general, they are asymptomatic, but they can also be associated with recurrent abortions or infertility. This is the case of a 27-year-old nulliparous woman presenting with the history of seven consecutive first trimester spontaneous abortions. Since her marriage 10 years back she conceived on repeated times but all the pregnancies ended in spontaneous miscarriage at around 10–12 weeks. Hysterosalpingography revealed a bicornuate/septate uterus. Hysteroscopic septoplasty with concurrent laparoscopy was planned after normalization of the endocrine parameters. She conceived spontaneously 7 months after the surgery. She had luteal phase support with progesterone, cervical cerclage and management of gestational diabetes, and pregnancy-induced hypertension. At 37 weeks of gestation, elective caesarean section was done with the delivery of a healthy female baby.

Association study of six candidate genes with major depressive disorder in the North-Western population of Pakistan

People around the world are currently affected by Major Depressive Disorder (MDD). Despite its many aspects, symptoms, manifestations and impacts, efforts have been made to identify the root causes of the disorder. In particular, genetic studies have concentrated on identifying candidate genes for MDD and exploring associations between these genes and some specific group of individuals. The aim of this research was to find out the association between single nucleotide polymorphisms in 6 candidate genes linked to the neurobiology of major depressive disorder in the North-Western population of Pakistan. We performed a case-control analysis, with 400 MDD and 232 controls. A trained psychiatrist or clinical psychologists evaluated the patients. Six polymorphisms were genotyped and tested for allele and genotype association with MDD. There were no statistical variations between MDD patients and healthy controls for genotypic and allelic distribution of all the polymorphisms observed. Thus, our analysis does not support the major role of these polymorphisms in contributing to MDD susceptibility, although it does not preclude minor impact. The statistically significant correlation between six polymorphisms and major depressive disorder in the studied population was not observed. There are inconsistencies in investigations around the world. Future research, including GWAS and association analysis on larger scale should be addressed for further validation and replication of the present findings.

Correlation between Length of Ala and Transverse Diameter of First Sacral Vertebral Body in both Sexes

Sacrum is a triangular bone formed by the fusion of five sacral vertebrae. It is situated near the lower end of the spinal column, where it joins both hip bones to form the posterio superior wall of the pelvic cavity. It is an important bone for identification of sex in human skeletal system. This cross sectional and descriptive study was done among 150 (59 male and 91 female) fully ossified dry human sacrum in Mymensingh Medical College, Mymensingh, Bangladesh from January 2017 to December 2017. The sex of sacrum was determined by previously measured different parameters. Sample collection was done by purposive sampling technique from anatomy department of Mymensingh Medical College and Community Based Medical College of Bangladesh, Mymensingh. The parameters included the length of ala and transverse diameter of first sacral vertebral body which were measured by digital vernier slide caliper and was expressed in mm. In present study the mean length of ala in male and female were 29.21±6.30mm and 30.77±5.56mm respectively. The mean transverse diameter of first sacral vertebral body in male and female were 48.10±4.83mm and 44.05±6.16mm respectively. Comparison of both length of ala and transverse diameter of first sacral vertebral body was done between male and female by unpaired student 't' test which was statistically significant. There was positive correlation between these two parameters and the differences were statistically highly significant in both sexes.

Antidiabetic and Hypolipidemic Potential of Green AgNPs against Diabetic Mice

Green nanotechnology-based approaches have been acquired as environmentally friendly and cost effective with many biomedical applications. The present study reports the synthesis of silver nanoparticles (AgNPs) from the leaves of Emblica phyllanthus, characterized by UV-Vis spectroscopy, EDX, SEM, AFM, and XRD. The acute and chronic antidiabetic and hypolipidemic potential of AgNPs was studied in alloxan-induced diabetic mice. A total of 11 groups (G1-G11, n = 6) of mice were treated with different concentrations (150 and 300 mM) and sizes of AgNPs and compared with those treated with standard glibenclamide. A significant decrease (P > 0.05) in the glucose level was achieved for 30, 45, and 65 nm after 15 days of treatment compared to the diabetic control. The oral administration of optimal AgNPs reduced the glucose level from 280.83 ± 4.17 to 151.17 ± 3.54 mg/dL, while the standard drug glibenclamide showed the reduction in glucose from 265.5 ± 1.43 to 192 ± 3.4 mg/dL. Histopathological studies were performed in dissected kidney and liver tissues of the treated mice, which revealed significant recovery in the liver and kidney after AgNP treatment. Acute toxicity study revealed that AgNPs were safe up to a size of 400 nm and the raw leaf extract of Emblica phyllanthus was safe up to 2500 mg/kg b.w. This study may help provide more effective and safe treatment options for diabetes compared to traditionally prescribed antidiabetic drugs.

Doppler Evaluation of Carotid Vessels in Type 2 Diabetes

Type 2 diabetes considered as a compound of metabolic syndrome. It can cause both micro and macrovascular complications. Diabetes is a strong risk factor in the development of atherosclerosis and likewise carotid artery disease. Carotid artery stenosis may cause stroke. Doppler ultrasound is the most common imaging technique for the diagnosis of carotid disease. Objective of the study was to assess the percentage of atherosclerotic carotid disease in asymptomatic Type 2 diabetics (T2D) by Doppler sonography and to find out the association of different risk factors of diabetic patient with atherosclerosis. A cross sectional study was done. A total of 43 type 2 diabetic patients (27 male, 16 female) referred from the out patient department and admitted patients in Mymensingh Medical College Hospital (MMCH) during January 2017 to December 2017 for the purpose of evaluation of intima media thickness (IMT) and carotid artery stenosis by Duplex color Doppler ultrasonography examination were enrolled in this study. Patients with previous history of recent stroke or transient ischemic attack (<6 weeks), history of carotid surgery or cervical radiotherapy were excluded. Carotid artery disease was found 65.1% in asymptomatic type 2 diabetics. Among them increased IMT in 48.8% and carotid stenosis was present in 37.2% and >50% stenosis (Peak systolic velocity >125cm/sec) was present in 9.3%. Age >50% years, smoking, duration of DM >10 years, hypertension, history of ischaemic heart disease and history of diabetic retinopathy were found to be associated with carotid atherosclerosis as well as carotid stenosis. High percentage of carotid artery disease (65.1%) was found in asymptomatic type 2 diabetes mellitus. This result suggests the need for carotid Doppler evaluation of all Type 2 diabetics as a first measure of stroke prevention, with the hope that timely intervention might avert stroke and its accompanying disability.

Prevalence of Diabetic Nephropathy in Patients Attending the Endocrine Department of Mymensingh Medical College Hospital

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease worldwide. Due to severe morbidity and mortality of DN and limited effective therapies, research has mainly focused on prevention of this debilitating illness by modification of risk factors. Aims of this study were to find out the prevalence of diabetic nephropathy, its factors and to correlate the functional status of the kidney. This cross-sectional study was conducted in the Department of Endocrinology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from 1st January 2013 to 30th June 2013. A total 105 patients having clinical diagnosis of Diabetes mellitus were enrolled in this study. Data were collected by interview of the patients, clinical examination and laboratory investigation. Data was analyzed using the Chi-square test for Categorical variables and unpaired Student's 't' test for differences in means for continuous variables. P value <0.05 was considered significant. With DN (30.5%) patients 21.1% had micro-albuminuria and 9.5% had macro-albuminuria. The mean age for the DN patient was 47.9±14.7 years and male female ratio was 1:1. BMI was found significantly low in patients with DN (p<0.05). Prolonged duration of diabetes (>5 years) and uncontrolled diabetes were found as significant risk factors associated with DN. Other risk factors were hypertension, family history of hypertension, family history of diabetes mellitus and irregular treatment of diabetes mellitus. Mean serum creatinine, mean estimated glomerular filtration rate (GFR) and mean blood sugar level was 1.3±0.6mg/dl, 69.4±26.7ml and 15.6±7.1mmol/L respectively in DN patients. Relation was significant for higher serum creatinine and lower eGFR values (p<0.05). Prevalence of diabetic nephropathy was 30.5%. Long standing diabetes (>5 years) and uncontrolled diabetes were the important risk factors for the development of diabetic nephropathy. Diabetic nephropathy is associated with higher serum creatinine and lower eGFR values.

Length of Umbilical Cord in Different Gestational Age Groups of Healthy Pregnant Mother of Bangladesh

This cross sectional descriptive study was performed on 80 human placenta and umbilical cord to find out the variation in length of umbilical cord of healthy Bangladeshi mother in relation to different gestational age. This study was conducted in the Department of Anatomy, Mymensingh Medical College, Mymensingh, from January to December 2018. The specimens were collected from the Department of Gynaecology and Obstetrics, Mymensingh Medical College Hospital, Mymensingh, Bangladesh by purposive sampling technique. According to gestational age the collected samples were divided into three groups. They were Group A (28 to 36 weeks), Group B (37 to 40 weeks) and Group C (above 40 weeks) and examined morphologically by fine dissection method. The length of umbilical cord was measured with the help of flexible tape in cm. For statistical analysis, differences of length between age groups were analyzed by using unpaired student 't' test. The mean±SD length of umbilical cord was 56.15±7.61cm in Group A, 62.54±8.78cm in Group B and 68.54±10.53cm in Group C. It was also observed that the mean length of the umbilical cord was increased with increase of gestational age. The mean difference of length of umbilical cord between Groups A and C was statistically highly significant (p<0.001), difference between Groups A and B was statistically moderately significant (p<0.01) but the difference between Groups B and C was statistically significant (p<0.05). This study was done to provide information about the length of umbilical cord in different gestational ages of healthy pregnancies.

Patterns of maternal nutritional status based on mid upper arm circumference

OBJECTIVE

To determine the patterns of maternal nutrition status by using mid upper arm circumference (MUAC) and to examine the association of maternal nutritional status with the nutritional status of malnourished children under two years of age.

METHODS

Descriptive study conducted at the Department of Pediatric Medicine of the Children's Hospital, Lahore from January 2017 to March 2018. A total of 227 mother accompanying their children admitted for nutritional rehabilitation were included. Demographics of participants along with MUAC of every mother was taken. Data analysis was done by SPSS 22.

RESULTS

Mean maternal age was 28.29±5.30 years and mean age of children was 9.22 ± 6.05 months. Mean maternal MUAC was 25.53±3.63 cm. Normal nutrition was present in only 70 (31%), 35 (15.4%) had moderate to severe under nutrition and 68 (30%) were overweight and 17 (7.5%) were obese. Maternal illiteracy was common 150 (66%) and 203 (89%) belong to poor social class. Majority 150 (75%) children had <-3SD WHZ score. Only 42 (18.5%) children were exclusively breast fed. Maternal malnutrition was significantly associated with severity of child's undernutrition (p=0.045) and low rates of exclusive breast feeding practices (p=0.049).

CONCLUSION

Malnutrition, in the form of both under nutrition and obesity is prevalent in mothers of malnourished children belonging to lower social class. Maternal illiteracy and low income are the major contributor in maternal malnutrition which in turn has an impact on child nutrition and breast feeding practices.

Potential effect of the microbial fermented feed utilization on physicochemical traits, antioxidant enzyme and trace mineral analysis in rabbit meat

The study investigated the potential effect of the microbial fermented feed utilization on physicochemical traits, antioxidant enzyme and trace mineral analysis in rabbit meat. A total of 72 six-week-old male rabbits were weighed and randomly divided into four groups (1) (SRKC) control; (2) (SRKP) Lactobacillus plantarum 1 × 10⁶  cfu/g fresh weight (FW); (3) (SRKG) Pediococcus acidilactici 1 × 10⁶ cfu/g FW and (4) (SRKPG) P. acidilactici + L. plantarum 1 × 10⁶ cfu/g FW. Performance characteristic, weekly body weight, was positively (p < .05) enhanced, while daily feed intake (DFI) and feed convention ratio (FCR) were not influenced in treatments group as compared to untreated. The water, protein, water holding capacity (WHC) and dry matter (DM) concentration were positively (p < .05) influenced, while ash, pH, lightness, redness and yellowness were not influenced in treated group as compared to untreated. The concentration of glutathione peroxidase (Gpx), superoxide dismutase (SOD) and aspartate aminotransferase (AST) was positively (p < .05) influenced in treatments group as compared to control. Regarding trace minerals, copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) were positively (p > .05) reduced in treated group as compared to untreated. It is concluded that the addition of lactic acid bacteria (L. plantarum and P. acidilactici) in Hybrid pennisetum silage had a constructive influence on rabbit health performance and meat biochemistry.

Biological and biochemical characteristics of male reproductive system, serum metabolites and carcass quality of Japanese quails by the supplementation of Pinus ponderosa leaves and α-tocopherol acetate

The aim of the current study was to evaluate the effect of dietary supplementation of Pinus ponderosa leaves (pine leaves) and α-tocopherol acetate (vitamin E) powder on male reproductive system, serum metabolites and carcass characteristics of Japanese quails. A total of 360-day-old male quails were purchased from the open market and kept at poultry shed for ninety-four days. After ten days of adaptation, all quails were randomly assigned into 4 groups, control (IC); supplemented with α-tocopherol acetate (IE) at the rate of 150 mg/L; Pinus ponderosa leaves (IP) at the rate of 150 mg/L; and 70 mg α-tocopherol acetate and 70 mg Pinus ponderosa leaves (IEP). Pinus ponderosa leaves and α-tocopherol acetate supplementation had not significantly (p > .05) effected on final body weight gain, feed intake and feed conversion ratio of quails. The high-density lipoprotein cholesterol (HDLC) and total cholesterol (TC) were significantly (p > .05) affected by IE and IP groups as compared to IC and IEP groups. Triglyceride (TG), glutathione peroxidase (GPx) and superoxide dismutase (SOD) significantly (p < .05) increased in all treatment groups except for the IC group. Aspartate transaminase (AST) significantly (p > .05) decreased in treatment groups as compared to control group. Overall, the mineral levels significantly (p < .05) increased in treatment groups as compared to control. Cloacal gland index values, the quantity of foam production and testis weight were significantly (p < .05) increased in treatment groups. It was concluded that the supplementation of Pinus ponderosa leaves and α-tocopherol acetate improved the testis weight, foam production, serum antioxidant enzymes and mineral level especially zinc in Japanese quail considered an indicative characteristic of higher sperm production rate and improved sexual activity. Further, higher gametogenesis rate, sperm production or reproductive behaviour including different hormonal level will be analysed in future study.

Prognostic factors and outcome of Post-Neonatal Tetanus in an intensive care unit of a Tertiary Care Hospital

OBJECTIVE

To determine the prognostic factors and outcome of tetanus in children of post-neonatal age admitted in the intensive care unit (ICU) of a tertiary care hospital.

METHODS

This prospective cross sectional study, carried out in the Pediatric ICU of The Children's Hospital Lahore from Jan 2013 to March 2017. Children of both genders with age range of two months to 16 years diagnosed clinically as tetanus were included. All 132 patients were scrutinized for all possible risk factors, need for mechanical ventilation and outcome. Data was analyzed by SPSS version 20.

RESULTS

Mean age of children was 7.5±3.4 years with male predominance (70.5%). Only (38.6%) received three doses of vaccination but none had booster dose. Trauma (43.2%) encompassed maximum predisposing factor followed by ear or nose prick and ear discharge. Mean duration of ICU stay was 20±13.3 days. Mortality rate was (17.4%). Ventilator support was given to (78.8%). Neurological outcome was normal in (82.6%). Trauma, ear or nose prick in girls and ear discharge were significantly associated with poor outcome and death with p-value of <0.001, 0.011 and <0.001 respectively. Other factors associated with poor outcome were need for mechanical ventilation and neurological impairment with p-value of 0.001 and <0.001 respectively.

CONCLUSION

Tetanus is causing our children to suffer from devastating disease. Vaccination status is not satisfactory and along with trauma, ear discharge and ear or nose prick are identifiable risk factors. To combat these issues large scale vaccination and booster doses remains promising option.

Diagnostic Evaluation of Isotropic 3D MRCP Images in the Diagnosis of Cholangiocarcinoma

This is a cross sectional study to establish that Magnetic resonance cholangiopancreatography (MRCP) could be accepted as the most effective imaging modality for the diagnosis of cholangiocarcinoma. Cholangiocarcinoma is the most common malignant tumor of the bile duct. It is much less common than hepatocellular carcinoma, accounting for 5-30% of all hepatic malignancies. Clinically suspected patients with obstructive jaundice due to cholangiocarcinoma were referred to the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. The study was carried out in 60 patients, of which 38(63%) were male and 22(37%) were female. Out of 60 cases 56 cases were truly diagnosed by MRCP, 4 were normal, among these 1 case was diagnosed as cholangiocarcinoma as compared with histopathology. Forty four (44) patients (73.2%) of the patients were in sixth decade of life. The overall sensitivity and specificity were found to be 98.2% and 75%. The diagnostic accuracy was 96.7% & positive predictive value was about 98%.

Report: Occurrence of Aflatoxin M1 in raw and processed milk consumed in Pakistan

Aflatoxin M1 (AFM₁) is a hydroxylated metabolite of Aflatoxin B₁ (AFB₁). It appears in milk, when lactating animals consume AFB₁ contaminated feed. It is carcinogenic and teratogenic in nature. Present study was planned to determine levels of AFM1 in raw and processed milk. For this, a total of five hundred and seventy milk samples (raw = 340 and processed = 230) were collected from Punjab (province of Pakistan). Processed milk included ultra-heat treated (UHT) (n=105), pasteurized (n=65), dried (n=40) and condensed milk (n=20). Concentration of AFM1 was quantified by direct competitive ELISA technique. Analysis revealed 100 percent incidence of AFM₁ in UHT and pasteurized milk with a mean of 0.35±0.28ng/ml and 0.11±0.03ng/ml respectively. However, 86.66% raw milk samples were tainted with AFM1 with mean of 0.52±0.42ng/ml and 66.66% of dried milk samples with mean of 0.03±0.02ng/ml. However, none of the condensed milk sample was found positive. Data of raw milk contamination was further computed for seasonal variation. Highest prevalence (100%) was observed during autumn season followed by winter (81.81%), summer (80%) and spring season (62.06%) respectively. Furthermore, all mean values except raw milk were below the FDA legislation. Study results indicate the possible adverse effects on health of people of Pakistan. Good agriculture practices (GAP) and regular screening of raw materials of animal feed prior to supplying may help to control AFM₁ levels in milk.

Variations in the Position of Vermiform Appendix in Bangladeshi People

This cross sectional descriptive study was performed on 70 postmortem vermiform appendices (male 34 and female 36) to find out the various positions of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique from October 2016 to March 2017. The collected samples were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). Dissection was performed according to standard autopsy technique. During postmortem examination abdominal cavity was routinely exposed by classical midline incision from xiphoid process to the symphysis pubis and a semicircular incision around the umbilicus and the flaps were reflected to give a good view of the abdominal cavity along with its contents and then the taeniae coli of the caecum were identified. The three taeniae coli of the caecum converge at the base of the appendix and become its longitudinal muscle coat. The anterior caecal taeniae coli acts as the best guide for identification of the vermiform appendix. The relation of the base of the appendix to the caecum is constant but the position of the vermiform appendix, which is variable, was studied in relation to caecum and the terminal part of the ileum. Accordingly the position of the vermiform appendix was noted either retrocaecal, pelvic, preileal or postileal, subcaecal. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. Among 70 specimens, 44(62.9%) vermiform appendices were retrocaecal in position. The next common position was pelvic which was in 22(31.4%) specimen followed by postileal in 3(4.3%) specimen and subcaecal was observed only in 1(1.4%) specimen. In this study in all age groups incidence of retrocaecal vermiform appendix was highest and it was about 67.6%, 50%, 69.2% and 72.7% in Group A, B, C, D respectively. Pelvic position was 7.1%, 46.9%, 23.1% and 27.3% in Group A, B, C, D respectively. Subcaecal vermiform appendix was absent in Group A, B and Group D. On the other hand postileal vermiform appendix was absent in Group C and Group D. The findings of this study may help the physician and the surgeons for proper diagnosis, management and treatment of disease of vermiform appendix.

Performance of Haematological Parameters in Early Diagnosis of Clinically Suspected Neonatal Sepsis

Neonatal sepsis is one of the major health problems throughout the world and major cause of morbidity and mortality in developing countries. Positive blood culture considers the gold standard for confirmation of neonatal sepsis, but it does not provide rapid diagnosis. So this study was designed to find out the performance of haematological parameters in early diagnosis of neonatal sepsis. The objective of the study was to evaluate the performance of haematological parameters individually and in combination in early diagnosis of neonatal sepsis. It was a cross-sectional study conducted at neonatal ward, SCANU and obstetric ward of Rangpur Medical College Hospital from January 2014 to December 2015. A total of 70 neonates clinically suspected to have features of sepsis were included in this study. Another 70 healthy term neonates were included in the study as reference group. Blood sample were obtained to estimate TLC, ANC, immature neutrophil count, degenerative changes in PMNs, platelet count, I/T and I/M ratio. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the individual test and tests combination were calculated. Among the haematological parameters, performance of combined tests had high sensitivity, specificity, with PPV and NPV. Among the individual tests I/T and I/M ratio had high sensitivity (95%), specificity (85%, 90%), PPV (90%, 75%) and NPV (90%). There were 22 out of 70 neonates (31.42%) who had culture proven sepsis. Among 22 culture proven sepsis most commonly found organism were Escherichia Coli 12(54.5%) followed by Klebsiella 3(13.63%), Proteus 3(13.63%), Staphylococcus aureus 2(9.9%) and Salmonella 2(9.9%). There is no ideal test for diagnosis of early diagnosis of neonatal sepsis haematological parameters is useful adjunct test in identifying clinically suspected neonatal sepsis.

Antibiotic susceptibility profile of bacterial isolates from post-surgical wounds of patients in tertiary care hospitals of Peshawar, Pakistan

Postoperative wound infections are the infections of the operating site within thirty days after surgery. The infections that develop after surgery are a major problem throughout the world leading to, increased morbidity and mortality. This study was carried out to determine the prevalence of bacterial pathogens causing wound infection in the surgical wards and to determine the antimicrobial sensitivity patterns of the isolated bacteria. A total of 250 wound samples were collected over a period of 6 months from July-December, 2016. The pathogenic bacteria were isolated, identified and their antibiotic susceptibility was determined through disc diffusion method. Among 250 cases, 210 (84%) were culture positive for bacterial pathogens, while 40 (16%) were bacteriologically sterile (Negative). Rate of infection was high in males (55.6%) than females (44.4%). The predominant isolates were E.coli 55 (26.19%), followed by S.aureus 51 (24.28%), Pseudomonas spp. 43(20.47%), S.aureus MRSA 21 (10%), Proteus Marbillis 15 (7.14%), E.coli ESBL producer was 8 (3.81%), Acinetobacter 7 (3.33%) Proteus valgaris 5 (2.38%), b-Streptococci 3 (1.43%) and Klebsella pneumonia were the least, 2 (0.95%). Linezolid, Vancomycin, Amoxycillin, Cefoperazone and Meropenem are the most effective antibiotics for treating post-surgical wound infections.
