Trans-radial Angioplasty of Anomalous Origin of Right Coronary Artery: A Single-Centre Experience.

Successful percutaneous coronary intervention (PCI) to anomalous coronary arteries is technically challenging, particularly through transradial route. The application of appropriate techniques and devices may help overcome these challenges. The objective of this study is to explore the technical and procedural challenges in percutaneous coronary intervention (PCI) of anomalous origin of right coronary artery (AORCA) through the trans-radial route. This prospective study consisted of 25 consecutive patients who underwent PCI for an angiographically significant stenosis in AORCA from November 2017 to May 2019 at Ibrahim Cardiac Hospital & Research Institute (ICHRI). Demographic details and procedural data including numbers of catheters used, access, hardware, techniques, duration of procedure, volume of contrast and complications were recorded and statistically analyzed. The origin of AORCA was 48.0% each from the right and left coronary sinus, with 4.0% arising from the ascending aorta. Among those of right coronary sinus origin, superior take off was 83.3% and inferior take-off was 8.3%, with a further 8.3% originating from the left main, with a common origin with the left anterior descending (LAD) artery, from right coronary sinus. The mean age was 55.8±7.5 years. Diabetics were 84.0%, hypertensive 88.0%, dyslipidemic 68.0% and 20.0% had a history of smoking. Percutaneous coronary intervention (PCI) was performed successfully in 100.0% cases. Transradial access was the default route for coronary angiography in all cases. Angioplasty was performed trans-radially in 92.0% and trans-femoral in 8.0%, for two cases requiring switch over from radial to femoral route. The average number of guide catheters used was (2.0±1.0), (range: 1-4). The guide catheter hooked the coronary ostium selectively in 32.0%, off ostium in 56.0% and deep intubation was done in 12.0% cases. Anchoring wire to enhance guide support was used in 12.0%. 6 Fr guide extension catheter Guidezilla was used in 8.0% cases. The average duration of the procedure was 39.4 (range; 15-90) minutes, the average volume of contrast used was 67.0 (range: 30-150) ml. Average stent length was 28.6 (range; 12-43) mm. For PCI, Judkin's left (JL) and Judkin's Right (JR) were most commonly used guides (36.0% and 28.0% respectively), followed by multipurpose angled (MPA) guide (12.0%). The majority of the lesions stented were of ACC/AHA classification of type B (48.0%) followed by type A (36.0%) and type C (16.0%). Thrombus extraction was performed in a single case. One case was complicated by coronary artery dissection. PCI of AORCA through transradial route is technically challenging but feasible with a reasonable amount of contrast and radiation, and appropriate use of guides and techniques. Proper localization of ostium and selection of suitable guide is the key to success, aided by additional devices in the armamentarium of interventional cardiology such as guide extension catheter and anchoring wires.

Association of Low Vitamin D Level with Pelvic Organ Prolapse in Post Menopausal Women: A Case Control Study.

Pelvic organ prolapse refers to protrusion of the pelvic organ into or out of the vaginal canal. One in four women in the USA suffer from some type of pelvic floor disorder including pelvic organ prolapse and frequency of pelvic organ prolapse is more with increasing age. In Bangladesh, 15.6% women suffered from pelvic organ prolapse and more than 11.0% of women require surgical correction of prolapse in their life times. According to few researches, there is an observed association between low vitamin D levels with pelvic organ prolapse but this finding is not unequivocal. This case control study has been conducted in the Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from October 2018 to August 2020 to investigate the level of vitamin D in patients with and without pelvic organ prolapse to explore the association of low vitamin D with pelvic organ prolapse. A total 148 participants of 52 years or older attending the out or inpatient department were enrolled in the study. The study population was divided into two groups, a case group (n=74) consisting of patients with pelvic organ prolapse and a control group (n=74) comprising of women without pelvic organ prolapse. After taking informed written consent the serum vitamin D level of all participants was measured by CMIA technology with flexible assay protocols at Biochemistry and Molecular Biology department of the same institute. All necessary Data were collected on variables of interest by using the structured questionnaire pre-designed for interview, observation, clinical examination, and biochemical Data collection. Distributions were expressed by mean and standard deviation for continuous variables and by frequency and percentage for qualitative variables. Student's t-test and Chi square test were done to see the significance of differences between Group I and Group II. Odds ratio, correlation coefficient, and multivariate logistic regression analysis was done to assess the association of low vitamin D level with pelvic organ prolapse. Mean±SD level of Vitamin D in the case group was 13.96±5.18ng/ml and in the control group was 21.08±5.77ng/ml respectively. The difference was statistically significant (p<0.05). Moreover, the vitamin D levels were inversely proportionate with the severity of pelvic organ prolapse. OR (95% CI), of two groups showed risk of developing pelvic organ prolapse 5.63 times higher in women with decreased vitamin D level. Thus it can be concluded that women having low level of vitamin D have more chance of developing pelvic organ prolapse.

Association of Dyslipidemia with Endometriosis: A Case Control Study.

Endometriosis is a chronic multi-factorial disease characterized by the presence of functioning uterine glands and stroma in any site outside the uterus. Despite the major public health impact of this condition, little is known about their etiologies. Some studies focused on the similarities between the common biological mechanisms underlying the development of endometriosis and atherosclerotic plaques. So, it is possible to hypothesize that same atherogenic risk factors, such as dyslipidemia may play a role in endometriosis pathogenesis. This case-control study was carried out in the department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from September 2018 to August 2019 to investigate the lipid profile in patients with endometriosis and to analyze the association of dyslipidemia with endometriosis. A total of 140 participants ranged between 18 and 35 years of age attending BSMMU were enrolled in the study. The study population was divided into case and control group; the case group consisting of patients with endometriosis and control group comprising of healthy women without endometriosis. Fasting lipid profile of all participants was measured in the department of Biochemistry and Molecular Biology of BSMMU, Bangladesh. Doing student's t-test and Chi square test compared results of both groups. Logistic regression analysis was done to see association of dyslipidemia with endometriosis. Women with endometriosis were found to have significantly higher levels of serum total cholesterol (TC), low density lipoprotein (LDL-C), triglyceride (TG) and significantly lower level of high density lipoprotein (HDL-C) compared to the controls (p<0.05). The mean atherogenic index was significantly higher in case group (p<0.05). This study found an association between dyslipidemia and endometriosis.Women with endometriosis have higher atherogenic index compared to women without endometriosis.

Relationship between Free Testosterone and Preeclampsia.

Preeclampsia is associated with reduction of utero-placental blood flow, which is reflected in high blood pressure and proteinuria during the second half of pregnancy. Hyper-androgenism may be implicated in the pathogenesis of preeclampsia, if so, there should be a difference between the levels of testosterone in pregnant women complicated with preeclampsia and those without this complication. This case control study was carried out in the department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from September 2016 to August 2017 to find out the relationship between free testosterone and preeclampsia. A total 110 pregnant women during third trimester of pregnancy were enrolled in this study. Among them 70 pregnant women with preeclampsia were considered as case and 40 healthy normotensive pregnant women were considered as control. 5.0ml of blood was collected from every patient to measure free serum testosterone level by the DRG free Testosterone ELISA kit. ANOVA, Chi square test, student t test, Pearson's correlation coefficient, and Spearman's rank test were used for statistical analyses. A "p" value <0.05 was considered as significant. High serum free testosterone was found in 74.3% preeclampsia patients and in 7.5% healthy pregnant patients. The difference was statistically significant (p<0.05) having OR=35.63 with 95% CI. A significant positive correlation was found between systolic (r=0.289, p=0.009), and diastolic blood pressure (r=0.337, p=0.002) with free testosterone. Levels of the free testosterone were significantly higher in women with preeclampsia than in normotensive women, thus testosterone might have role in the pathogenesis of preeclampsia.

Study on Association of Maternal Serum Triglyceride with Pre-eclampsia.

Till now pre-eclampsia is a disease of multiple theories. This case control study was carried out in the department of Obstetrics and Gynaecology of Bangabandhu Sheikh Mujib Medical University Hospital and Dhaka Medical College Hospital, from January 2006 to December 2007 to determine the association of maternal serum triglyceride with pre-eclampsia. Ninety pregnant women were studied, among them 45 patients were pre-eclamptic and served as case and 45 normal healthy pregnant women served as control. Estimation of serum triglyceride levels of all study patients was done with the help of enzymatic method. The mean (± SD) systolic blood pressure was 152.4 ± 19.8 mmHg in study group and 112.0 ± 8.9 mmHg in control group (p<0.05). Similarly the mean (± SD) diastolic blood pressure was 103.1 ± 12.2 mmHg in case group and 75.5 ± 6.6 mmHg in control group (p<0.05). Serum triglyceride level was more than the normal reference value in pre-eclamptic group. The mean (± SD) serum triglyceride level was 242.9 ± 36.8 mg/dl in case group and 184.6 ± 12.5mg/dl in control group. Statistically the difference was significant (p<0.05). The level of serum triglyceride positively correlated with the rise of blood pressure and degree of albuminuria. Thus serum triglyceride level increase in pre-eclampsia and the level correlate with the severity of the disease.

Pregnancy with myasthenia gravis.

Myasthenia gravis (MG) is an autoimmune disorder of the neuromuscular transmission, caused by auto antibodies against the nicotinic acetylcholine receptor. These antibodies of the IgG isotype are detected in 80-90% of generalized MG and in 50-70% of ocular MG. Seronegative MG is caused by humoral factors. Prevalence of MG lies between 1 in 10.000 and 1 in 50.000, with 2/3 of affected individuals being female. In the case of maternal myasthenia gravis, both the mother and the child may develop myasthenia symptoms with varying degrees of weakness and progressive fatigability of the skeletal muscles. Data for the case report were generated by reviewing labour, delivery, and postpartal records. We present a 26 years old lady who suffered from a generalized form of myasthenia gravis since the age of 15. She got herself admitted to a neurologic clinic for a myasthenic crisis when she was two and half months pregnant. The patient was treated with anticholinesterase medication, corticosteroids and intravenous immunoglobulin. Clinically, the patient's condition improved significantly during pregnancy. Delivery and the post delivery period were also normal for the patient. Myasthenia gravis especially when associated with pregnancy is a high-risk disease. As this disease predominantly occurs in women of reproductive age, it is important to be aware of this condition in obstetrics and its interdisciplinary diagnostic and therapeutic management is required.

Status of HIV infection among the pregnant women attending in outpatient department.

Human immunodeficiency virus (HIV) infection has been spreading rapidly in the developing countries and vertical transmission also taking place. This study has been done to find out the prevalence of HIV infection among the pregnant women, so that necessity of routine screening test can be identified. It is a cross sectional study. Five hundred two pregnant women were included. Three ml venous blood was taken and then HIV screening test was done by ELISA method. All reactive tests were confirmed by Western blot antibody testing. The positive cases were followed up and necessary treatment was given. Delivery was conducted in this hospital. Baby's blood was tested to see vertical transmission after 18 months. Most of the subject were educated housewife, mean age was 25 years. Six (6%) husband was overseas service holder, 12% were smoker and 1.6% had drug addiction. Eight (8%) subject had previous history of blood transfusion and 49% subject or her husband had history of surgery or got parental therapy. 2% subject gave the history of familial disharmony and 2% had multiple sex partners. HIV infection was found in 2 patients (0.4%). Both of them got infection from their husband. One husband was over seas service holder and another one was injecting drug user. For the prevention of spread, reduction of vertical transmission and providing early management to the positive patient all pregnant women should be screened for HIV routinely.

Characteristics of infertile couples.

The objective of the study was to evaluate the sociodemographic characteristics and to find out the causes of infertility among the couple attending out patient department of infertility unit in Bangabandhu Sheikh Mujib Medical University (BSMMU) from January to December 2007. This is a descriptive observational study. Data were analyzed done manually and statistical analysis was calculated by Statistical package for social sciences (SPSS) program. During this period 3184 patients were attended out patient department (OPD) of infertility unit (IU-I & II). Among them primary infertility was present in 1971(61.90%) and secondary infertility in 1213(38%) cases. One thousand four hundred and two (1402) patient's complete data were reviewed from OPD register book of IU-I. The mean duration of the infertility was 4.7(4.52) years. The mean age of female patient was 26.5±5.35 years. The mean age of male patient was 34.56±6.33 years. A positive male factor problem alone was found in 13% couples, female factors in 71.46% couples and unexplained infertility in 15.47% couples. Among the male factor Oligozoospermia (33.33%) was the most common cause of male infertility. Anovulation (52.16%) was the most common cause of female infertility and major cause of anovulation was Polycystic ovary syndrome (PCOS) (29.90%). Fibroid uterus, Bilateral tubal block and Pelvic inflammatory disease (PID) were significantly (p<0.001) higher in secondary infertility. Endometriosis and unexplained infertility were significantly (p<0.001) higher in primary infertility. Distribution of other causes of infertility was same for both primary and secondary infertility.

Ethical awareness in surgical management.

Getting information about disease has been suffering, the management needed, procedure and complication of that management, is the right of the patients. Giving that information to the patients is the responsibility of the physician/surgeons. The objective of this study was to assess the existing awareness of the surgeons and female patients regarding ethical issues of medical practices. This observational study was undertaken in the gynecological department of two tertiary hospital of the capital city of Bangladesh. One hundred fifty five patients were interviewed who were underwent surgical management for different gynecological problems. Mean age of the studied population was 41 (SD+/-10) years. All of them were from lower and lower middle economical classes. Sixty three percents (63%) were illiterate. Consent for the surgery was given by the husband in 52% cases, by son in 22% cases, by herself in 1% case and remaining by other relatives. About 50% of the patients did not know the name of their disease, 75% of them never talked with the surgeon. Only in 31% cases surgeon spontaneously explained them about her disease. Most of them had no knowledge about anaesthesia, operating time, need of blood transfusion, operating complications and long-term effects of the surgery they had. The result of this study showed very poor awareness about medical ethics and patient's right.

Tropane alkaloid production by shoot culture of Duboisia myoporoides R. Br.

This work demonstrates the presence of hyoscyamine and scopolamine at different stages of shoot regeneration from non-organogenic and organogenic calli. The 11-week-old non-organogenic calli contained 0.41+/-0.03 and 0.23+/-0.02 microg g(-1) dry wt hyoscyamine and scopolamine respectively. However, no root meristem was found in the calli. The alkaloids were absent in 2-week-old organogenic calli. The shoot-buds induced on the non-organogenic and organogenic calli did not contain these alkaloids. Hyoscyamine and scopolamine contents of the 6-week-old non-rooted shoots regenerated from non-organogenic calli were 7.8+/-0.1 and 6.5+/-0.4 microg g(-1) dry wt respectively and those in the 9-week-old non-rooted shoot regenerated from organogenic calli were 38.5+/-0.4 and 3.6+/-0.1 microg g(-1) dry wt respectively. Hyoscyamine and scopolamine contents of the 4-week-old roots regenerated from non-organogenic and organogenic calli were higher than those in the non-rooted shoots. Since the presence of hyoscyamine and scopolamine in the non-rooted shoot depends on the stage of differentiation, manipulation of culture environment may improve hyoscyamine and scopolamine contents of the non-rooted shoots.
