Background: Suxamethonium having its rapid onset and short duration of action makes this drug unique amongst the neuromuscular blocking drugs described so far. However, use of suxamethonium is associated with a large number of undesirable side effects. Objective: To evaluate clinical effects of high and low dose of suxamethonium and to determine whether lower dose of suxamethonium can be used for any beneficial effects in terms of its various adverse effects e.g. cardiovascular responses, post-operative muscle pains and intraocular pressure. Methods: A total of 100 patients were included in this prospective study. All these patients on preoperative clinical evaluation were assessed to have adequate airway. All the patients were divided in two groups, low dose group (group I) and High dose group (group II) with 50 patients in each at random. A standard anesthetic technique was adhered to all the patients and following parameters were observed on comparative basis: a. Fasciculation and post operative myalgia. b. Cardiovascular effects, c. Intraocular pressure. Observation: The incidence of post Suxamethonium pain was significantly greater in group II. Increase in heart rate from baseline was significant in both groups. There was no significant difference between the two groups in the diastolic pressure but rise in systolic blood pressure was significant at all assessment times in both groups. This rise from control was statistically significant. Conclusion: Suxamethonium can be used in lower doses (0.5 mg/kg) in elective cases without airway compromise. It gives benefits of reduced muscle pains, cardiovascular responses and intraocular hypertension.

ABSTRACTBackground: Induction of labour is an indispensable part of modern obstetrics and certainly one of the most frequently performed obstetric procedure in the world. Oxytocin, being the most common inducing agent with multiple protocols being practiced, further research is required for the establishment of better protocol with optimal maternal and neonatal outcomes.Methods: Randomized comparative study including 100 term nulliparous women (randomized into high dose, group-I and low dose, group-II with 50 patients in each group) was done. High dose regimen was started with 4mu/min with increment of 4mu/min up to a maximum of 32mu/min and low dose regimen was started with 2mu/min with increment of 2mu/min up to a maximum of 32mu/min. Induction to delivery interval was the primary outcome. Secondary outcomes noted were rate of caesarean section, tachysytole with or without fetal distress, failed induction, maternal outcomes like need for instrumental vaginal delivery, PPH and choriamnionitis, neonatal outcomes like NICU admission, umbilical cord pH and apgar score.Results: There was significant reduction seen in induction to delivery interval among those induced with high dose oxytocin regimen. It was found to be 6.96±3.77 hours in group-I and 9.05±4.65 hours in group-II (p value 0.034). Though incidence of tachysystole was more in high dose regimen, it was not statistically significant. No significant difference was seen in secondary outcomes.Conclusions: On the basis of present study, high dose oxytocin regimen can be considered for induction of labour as it has same effects as that of low dose regimen with lesser induction to delivery interval.

Abstract BACKGROUND Delayed cerebral ischemia (DCI) is one of the major causes of delayed morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). OBJECTIVE To evaluate the effect of high-dose nadroparin treatment following endovascular aneurysm treatment on the occurrence of DCI and clinical outcome. METHODS Medical records of 158 adult patients with an aSAH were retrospectively analyzed. Those patients treated endovascularly for their ruptured aneurysm were included in this study. They received either high-dose (twice daily 5700 AxaIE) or low-dose (once daily 2850 AxaIE) nadroparin treatment after occlusion of the aneurysm. Medical charts were reviewed and imaging was scored by 2 independent neuroradiologists. Data with respect to in-hospital complications, peri-procedural complications, discharge location, and mortality were collected. RESULTS Ninety-three patients had received high-dose nadroparin, and 65 patients prophylactic low-dose nadroparin. There was no significant difference in clinical DCI occurrence between patients treated with high-dose (34%) and low-dose (31%) nadroparin. More patients were discharged to home in patients who received high-dose nadroparin (40%) compared to low-dose (17%; odds ratio [OR] 3.13, 95% confidence interval [95% CI]: 1.36-7.24). Furthermore, mortality was lower in the high-dose group (5%) compared to the low-dose group (23%; OR 0.19, 95% CI: 0.07-0.55), also after adjusting for neurological status on admission (OR 0.21, 95% CI: 0.07-0.63). CONCLUSION Patients who were treated with high-dose nadroparin after endovascular treatment for aneurysmal SAH were more often discharged to home and showed lower mortality. High-dose nadroparin did not, however, show a decrease in the occurrence of clinical DCI after aSAH. A randomized controlled trial seems warranted.

Background. Daikenchuto (DKT) is a Kampo medicine used for the treatment of constipation. In this study, we evaluated the effectiveness of DKT against constipation. Patients and Methods. Thirty-three patients administered DKT for constipation were selected and divided into low-dose (7.5 g DKT; n=22) and high-dose (15 g DKT; n=11) groups. We retrospectively evaluated weekly defaecation frequency, side effects, and clinical laboratory data. Results. Median defaecation frequencies after DKT administration (5, 5.5, 5, and 8 for the first, second, third, and fourth weeks, resp.) were significantly higher than that before DKT administration (2) in all 33 cases (P<0.01). One case (3%) of watery stool, one case of loose stools (3%), and no cases of abdominal pain (0%) were observed. Median defaecation frequencies in the high-dose group (7 and 9) were significantly higher than those in the low-dose group (4 and 3) in the first (P=0.0133) and second (P=0.0101) weeks, respectively. There was no significant change in clinical laboratory values. Conclusion. We suggest that DKT increases defaecation frequency and is safe for treating constipation.

Background: Epilepsy is one of the major central nervous system disorders. The parent study aimed to screen the anticonvulsant effect of carvedilol on electrically induced convulsions in Wistar albino rats.Methods: This study was done in Wistar albino rats. A total of 30 rats were divided into 6 groups each of six rats. group-I (0.9% normal saline), group-II diphenylhydantoin (10 mg/kg/BW/ip), group-III carvedilol (1mg/kg/BW/PO), group-IV carvedilol (2 mg/kg/BW/PO) and group-V carvedilol (4 mg/kg/BW/PO). All the groups were administered drugs and subjected to electric shock. Scores of seizures and percentage of protection were recorded to compare between the groups. One was ANOVA (post hoc) followed by Dunnet t test applied to find the statistically significant between the groups.Results: Group-I showed significant difference compared to other groups. Group-II showed significant difference with group-III and IV not with V. High dose of test drug and standard drug showed similar results in percentage of seizures prevention. Control and low doses of test drugs showed significant difference compared to standard and high dose of test drug in seizures prevention.Conclusions: High of carvedilol showed significant seizures prevention compared to low doses and control group.

BackgroundLow dose dexamethasone demonstrated clinical improvement in patients with coronavirus disease 2019 (COVID-19) needing oxygen therapy; however, evidence on the efficacy of high dose of dexamethasone is limited.MethodsWe performed a randomised, open-label, controlled trial involving hospitalised patients with confirmed COVID-19 pneumonia needing oxygen therapy. Patients were randomly assigned in a 1:1 ratio to receive low dose dexamethasone (6 mg once daily for 10 days) or high dose dexamethasone (20 mg once daily for 5 days, followed by 10 mg once daily for additional 5 days). The primary outcome was clinical worsening within 11 days since randomisation. Secondary outcomes included 28-day mortality, time to recovery, and clinical status at day 5, 11, 14 and 28 on an ordinal scale ranging from 1 (discharged) to 7 (death).ResultsA total of 200 patients (mean (sd) age, 64 (14) years; 62% male) were enrolled. Thirty-two patients of 102 (31.4%) enrolled in the low dose group and 16 of 98 (16.3%) in the high dose group showed clinical worsening within 11 days since randomisation (rate ratio, 0.427; 95% CI, 0.216–0.842; p=0.014). The 28-day mortality was 5.9% in the low dose group and 6.1% in the high dose group (p=0.844). There was no significant difference in time to recovery, and in the 7-point ordinal scale at day 5, 11, 14 and 28.ConclusionsAmong hospitalised COVID-19 patients needing oxygen therapy, high dose of dexamethasone reduced clinical worsening within 11 days after randomisation as compared with low dose.

AbstractPirfenidone is an antifibrotic agent that has been proven to slow down the progression of idiopathic pulmonary fibrosis (IPF). The aim of this study was to evaluate the efficacy of low-dose pirfenidone (that is, less than 1200 mg/day). We retrospectively reviewed the medical records of patients with IPF. The patients were divided into the following three groups, those who were not treated with pirfenidone (control) and those who were treated with pirfenidone at doses < 1200 mg/day (low-dose group) and ≥ 1200 mg/day (high-dose group). The adjusted mean changes in forced vital capacity (FVC) in 1 year were − 200.7, − 88.4, and − 94.7 mL in the control, low-dose, and high-dose groups (p = 0.021). The FVC declined more significantly in the control group than in the low-dose and high-dose groups. No significant difference in FVC change was observed between the low-dose and high-dose groups. Dyspepsia, anorexia, and nausea were significantly more frequent in the low-dose than in the high-dose group, suggesting that dose reduction is attributed to gastrointestinal tract-related adverse events. Dose reduction may help patients to better control gastrointestinal tract-related adverse events; continuing taking the medication at low doses is also expected to be effective in reducing the FVC decline.

Background: The study evaluates the effect of a high supplemental dose of ascorbic acid (AA) on plasma concentrations of total cholesterol (TC), triglycerides (TG), total lipids (TL), and lipoprotein fractions high-density, very-low-density-, and low-density lipoprotein (HDL, VLDL, LDL) in guinea pigs fed with atherogenic diet. Methods: Group I consisted of 5 normally fed guinea pigs plus a low dose of AA (1 mg/100 g/day), group II consisted of 7 guinea pigs fed with food enriched with 2% cholesterol plus a low dose of AA (1 mg/100 g/day), and group III consisted of 7 guinea pigs fed with food enriched with 2% cholesterol plus a high dose of AA (30 mg/100 g/day). Cholesterolemic factors concentrations were determined after nine weeks. Results: Concentrations of TC, TG, TL, LDL, and VLDL were increased in group II compared to group I (p < 0.01 for all differences). Supplementation with a high dose of AA resulted in decreased concentrations of TC (p < 0.01), TG (p < 0.01), TL (p < 0.01), and LDL (p < 0.01) in group III compared to group II. Additionally, concentration of HDL was increased in group III compared to group II (p < 0.01). Conclusion: High-dose AA supplementation to an atherogenic diet decreases concentrations of TC, TG, TL, and LDL and increases concentration of HDL compared to low-dose AA.

Abstract Background: There are gender differences in the biotransformation of arsenic. We investigated the effects of gender differences on arsenic metabolism and arsenic toxicity mechanisms in rat liver tissues. Methods: Rats were treated with different amounts of arsenic compounds. Arsenic form MMA and DMA in the liver was determined by high performance liquid chromatography-hydride generation atomic fluorescence spectroscopy. SAM, ARR, NAD, PNP, PK, and MPO in rat liver were determined by enzyme-linked immunoassay. RT-qPCR was used to determine AS3MT in the liver. Results: Compared with male and female animals in the same group, MMA and DMA were statistically significant in the three groups of iAs3 + high, iAs3 + medium and iAs5+ low (P <0.05). The MMA of male rats in iAs3+ high and medium groups was higher than that of female rats, and the DMA of male rats was lower than that of female rats. As3MT mRNA in the male iAs3+ high group was higher than that of females. Besides, compared between male and female, only in iAS3+ low dose, iAS3+ medium dose, iAS5+ low dose, and iAS5+ medium dose groups, there was significant difference in SAM level (P<0.05). Compared with male and female animals in the same group, male rats had significantly higher PNP and ARR activities while lower PK activity than female rats (P<0.05). Between the male and female groups, only the iAS3+ high dose and medium dose group had a statistically significant difference (P<0.05). The NAD activity of females in iAS3+ high dose group was higher than that of males. Conclusion: Conclusively, under the same arsenic exposure, there were gender differences between female and male rats, and arsenic metabolism was more cytotoxic to male rats than to females.

Background: Migraine, the second most common cause of headache that can significantly impair the lives of people. Various drugs are available for migraine prophylaxis but all of which have varying degrees of adverse effects that may significantly limit their use.Objectives: To observe whether low dose topiramate is more effective compared to propranolol in migraine prophylaxis.Methods: Total 120 patients the age range of 18 to 50 years were recruited as study population of migraine in the Out Patient Department (OPD) & Headache Clinic,BSMMU.60 patients were administered by Tab.Topiramate 50 mg/ day named as group-I and rest of 60 patients were administered by Tab. Propranolol 80 mg /day named as group-II. Out of them in total 96 patients had completed the study. 47 patients had completed study in group-I and 49 patients in group-II. During trial, three follow up visits were taken for both groups, 1st follow up after 4 weeks of baseline information, 2nd follow up after 4 weeks of treatment, 3rd follow up after 8 weeks of treatment. Efficacy of treatment was measured by frequency, duration and severity of headache as measured by the visual analogue scale (VAS).Results: The mean (SD) age of group-I (topiramate) and group-II (propranolol) group were found 29.72±9.58 years and 30.96±10.11 years respectively. Female sex was found predominant in both groups. At final follow up, there was statistically significant difference in mean (SD) value of frequency of migraine between topiramate and propranolol group (4.72±2.80 vs. 3.48±2.20; p=0.024]. Propranolol appeared statistically significant than topiramate [TPM 5.53±2.98 vs. PRO 4.36±1.55; p=0.047].Regarding severity of headache, better results also were observed in the propranolol group than topiramate (p< 0.05). Both drugs appeared significant in efficacy measurement (p<0.001). Patient drop out was more in the topiramate group than the propranolol group (21.68 % vs. 18.34%). Furthermore, in the topiramate group, patients complained of more adverse effects than propranolol group (23.4% vs. 14.3%), which was statistically significant.Conclusion: The present study suggests that low dose topiramate and propranolol are effective for migraine prophylaxis in reduction of frequency, severity and duration of migraine individually and propranolol appears more effective compared to that of topiramate.J Shaheed Suhrawardy Med Coll, December 2017, Vol.9(2); 49-54

Purpose. To evaluate the safety and efficacy of a novel modified subscleral trabeculectomy technique in management of primary congenital glaucoma. Methods. This study included 25 infants diagnosed of having bilateral primary congenital glaucoma. For each patient, one eye was assigned to undergo subscleral trabeculectomy with trimming of the edges of the scleral bed (group I), while the contralateral eye underwent subscleral trabeculectomy with application of mitomycin C (0.4 mg/ml for 3 min) (group II). All the patients were followed up for a period of 14 ± 3 months (range 13–22 months). Results. 25 eyes were included in each group. Patients’ mean age was 2.5 ± 0.5 months (range 1.8–6.5 months). The mean preoperative intraocular pressure was 31 ± 4.9 mmHg and 32.1 ± 4.0 mmHg in group I and II, respectively. The mean postoperative intraocular pressure was 9.0 ± 1.0, 11.0 ± 3.2, 12.5 ± 0.9, 13.0 ± 2.9, and 15.5 ± 1.5 mm Hg in group I and was 10.3 ± 1.2, 12.0 ± 2.5, 13.5 ± 1.7, 15.0 ± 1.5, and 17.1 ± 2.8 mm Hg in group II at the first week and 1, 3, 6, and 12 months, respectively. There was no statistically significant difference between the mean intraocular pressure values recorded at both groups preoperatively and at each follow-up visit. Failure necessitating further surgical interventions was recorded in 4 eyes (16%) in group I as compared to 3 eyes (12%) in group II (P>0.05). Postoperative complications included mild hyphema, which occurred in one eye (4%) in group I and 2 eyes (8%) in group II, and shallow anterior chamber in 3 eyes (12%) in group I and in 2 eyes (8%) in group II. One eye (4%) in group I developed drawn-up pupil. Choroidal effusion developed in one eye (4%) at each group. Conclusion. Trimming the edges of the scleral bed adjacent to the sclera flap is a safe and effective surgical step which can be added to the subscleral trabeculectomy procedure to effectively control the intraocular pressure in patients with primary congenital glaucoma, sparing them the hazards associated with mitomycin C application.
