Cyclophosphamide and/or Anthracyclines Induced Epiphora in Breast Cancer Patients: A Rare Side-effect.

BACKGROUND: Two female breast cancer patients developed epiphora after administration of cyclophosphamide and/or anthracyclines based 2-day chemotherapy regimen. An ophthalmologist was consulted and no apparent cause was found. CASE DESCRIPTION: Patients were managed by ciprofloxacin eye drops. Chemotherapy induced ocular complications are not uncommon, but under reported. Although epiphora is a mild reaction, if severe however, it can interfere with daily activities. Patients having chemotherapy induced ocular toxicity should go for ophthalmic examination to pick up ocular adverse effects of anticancer drugs and treat them at an early stage.

Caregiver burden in Alzheimer-type dementia and psychosis: A comparative study from India.

BACKGROUND: Caregiver burden in dementia is an important area of research. Providing care for a relative can be a potent source of chronic stress and can have deleterious consequences for both the physical and emotional health of caregivers. This study aims to evaluate the burden of care in caregivers of patients with Alzheimer-type dementia and compare it with elderly psychosis; and to also study the factors that influence burden of care in Alzheimer's dementia. METHODS: Thirty-two caregiver-patient dyads of Alzheimer-type dementia were compared with thirty-two caregiver-patient dyads of psychosis. Cognitive assessment, abilities to perform activities of daily living and severity of dementia was assessed in the patients. Zarit Burden Interview was used to study the caregiver burden in both groups. RESULTS: The mean burden score in dementia caregivers was high at 47.7, whereas the mean burden score for elderly psychosis caregivers was lesser at 33.6, and this difference in mean burden scores was found to be statistically significant. Spouses had the highest mean burden scores of 53.48. Caregiver burden in dementia was positively correlated with cognitive impairment and inability to carry out ADLs. Presence of psychological distress in caregivers was also an indicator for greater caregiver burden in dementia. CONCLUSION: The study revealed that dementia carries a greater caregiver burden when compared with elderly patients with psychosis. Innovative interventions are needed to remove burden from caregiving, making it a meaningful practice integral to the Indian society.

Metronidazole and Norfloxacin induced Generalized Fixed Drug Eruptions in an adult male patient - A Case Report.

INTRODUCTION: Fluoroquinolones are most widely used for empirical treatment of gastrointestinal disease due to emergence of drug resistant strains to other antimicrobials. They are also indulged in cutaneous adverse drug reactions with varying form of severity. CASE PRESENTATION: A 43 year old male patient developed fixed drug eruptions after administration of tablet norfloxacin and metronidazole for treatment of colicky abdominal pain with diarrhoea. Erythematous rashes involved whole body including buccal mucosa. Causative drugs were stopped and patient was managed by local as well as systemic therapy and was recovered after 20 days. CONCLUSION: Awareness among healthcare professionals regarding FDEs and its management is essential to prevent mortality and morbidity and counsel patient regarding future use of drugs causing reactions with physician's advice.

Hospitalizations due to preventable adverse reactions-a systematic review.

PURPOSE: The study aimed to measure the percentage of preventable adverse drug reactions that lead to the hospitalization (PADRAd) and to explore the heterogeneity in its estimation through subgroup analysis of study characteristics. METHODS: Two investigators independently searched in electronic databases and related bibliography for prospective studies involving PADRAd. We excluded studies investigating medication errors and spontaneous and retrospective reporting. The primary outcome was PADRAd percentage. To explore the heterogeneity, we performed subgroup analysis based on study region, wards, age groups, adverse drug reaction (ADR) definitions, preventability assessment, ADR identification methods, study duration and sample size. We explored fatal PADRAd and causative drugs as a secondary outcome. We used the generic inverse variance method with random effect model to compute meta-analytic summary. RESULTS: Of the 68 full-text articles assessed, we included 22 studies. The mean PADRAd percentage was 45.11 % (95 % CI = 33.06-57.15; I 2 = 99 %). Studies including elderly (63.31 %) and all age groups (49.03 %) showed higher percentages than paediatric population (16.40 %). Studies examining all hospital populations showed higher percentages than specific wards. We observed high percentages in studies using Edwards and Aronson as an ADR definition and Hallas et al. as a preventability assessment tool. After age group adjustment, ADR detection methods did not show significant difference. The fatal PADRAd percentage was 1.58 % (95 % CI = -0.60 to 3.76; I 2 = 47 %). Paediatric and elderly studies showed a different causative drug pattern. CONCLUSION: Variation in PADRAd across the studies can be explained by difference in study populations and data collection methods. Extrapolation of preventable reactions should be carried out considering all these factors with caution.

Evaluation of cardioprotective effect of aqueous extract of Allium cepa Linn. bulb on isoprenaline-induced myocardial injury in Wistar albino rats.

To investigate the cardioprotective potential of the aqueous extract of Allium cepa Linn. bulb in isoprenaline-induced myocardial injury in Wistar albino rats. In vitro total phenolic, total flavonoid content and 2, 2'-diphenyl-1-picrylhydrazyl hydrate radical scavenging activity was measured. Isoprenaline-induced myocardial injury model was used to evaluate in vivo effect of aqueous extract of A. cepa in Wistar albino rats. Seventy two rats were randomly divided in 6 groups. Rats were treated with A. cepa 400 mg/kg and 800 mg/kg doses for 30 days and myocardial injury was produced by subcutaneous injection of isoprenaline (ISO) 85 mg/kg on day 28 and 29. Carvedilol 1 mg/kg for 30 days served as active control. Electrocardiogram parameters, cardiac injury markers, oxidative stress markers and histopathological changes were evaluated in each group and compared using appropriate statistical tests. In vitro evaluation of aqueous extract of A. cepa showed significant antioxidant property. ISO produced significant myocardial injury as compared to normal control group (P < 0.05). Administration of A. cepa in the dose of 400 mg/kg significantly recovered the altered parameters (Troponin-I, Creatine kinase-MB, glutamate-pyruvate transaminase, HR, R-R interval, and oxidative stress markers) compared to disease control group (P < 0.05) while A. cepa in the dose 800 mg/kg recovered the altered parameters (HR, heart weight/body weight ratio, and superoxide dismutase level) compared to disease control group. Histopathological parameters did not recover in the doses of 400 and 800 mg/kg (P > 0.05). The aqueous extract of A. cepa 400 mg/kg was found to be cardioprotective against myocardial injury while A. cepa 800 mg/kg did not show significant cardioprotective activity. So, we presume that A. cepa might be effective within certain dose range only.

Regular meetings will be helpful to solve the problems related to content of application forms. The uniformity in functioning of EC can be achieved if common application form for all ECs is there.

Social and legal aspects of marriage in women with mental illness in India.

The institution of marriage in Hindus is regulated by the prevailing social norms and the Hindu Marriage Act (HMA), 1955. Married women with mental illness are heavily discriminated. This paper examines the social and legal aspects of Hindu marriage in women with mental illness. The HMA, 1955 lays down the conditions for a Hindu marriage and also provides matrimonial reliefs: Nullity of marriage, restitution of conjugal rights, judicial separation and divorce. The application of the provisions of HMA in the setting mental illness is difficult and challenging. There is a wide gap between the legislative provisions of HMA, and societal value systems and attitudes towards marriage in Indian society. Societal norms are powerful and often override the legal provisions. The disparities are most glaring in the setting of mental illness in women. This is a reflection of social stigma for mental illness and patriarchal attitude towards women. Concerted efforts are needed to bridge the gap between the legislative provisions of HMA and societal value systems and attitudes toward marriage. Awareness programs regarding the nature and types of mental illness, advances in treatment and information about good outcome of severe mental illness will be helpful. Improvement in moral and religious values will overcome to some extent the negative attitudes and patriarchal mind set toward married women with mental illness.

Efficacy and safety of lornoxicam vs ibuprofen in primary dysmenorrhea: a randomized, double-blind, double dummy, active-controlled, cross over study.

OBJECTIVES: Study was planned to evaluate the efficacy and safety of lornoxicam in moderate to severe menstrual pain due to primary dysmenorrhea. STUDY DESIGN: This doubled blind, double dummy, randomized, comparable study of lornoxicam versus ibuprofen was conducted at Sir Takhtsinghji General Hospital, Bhavnagar, Gujarat, India. Total 57 primary dysmenorrhea participants having mean age±standard deviation (SD) of 19.2±2.08 were analyzed. The participants were randomly allocated to either lornoxicam 8 mg or ibuprofen 400mg two times a day for maximum of three days on two consecutive menstrual periods. The different medication was taken on each cycle. The analgesic efficacy was compared by a total area under pain relief score to 4 and 8h, pain intensity difference, sum of pain intensity difference to 4 and 8h, peak pain intensity difference to 4 and 8h, peak pain relief to 4 and 8h, total medication consumption, rescue medication and participant global evaluation. Adverse effects were recorded in both groups. RESULTS: In both treatments, efficacy parameters were significantly reduced at measured time points as compared to baseline. No significant difference was observed between lornoxicam and ibuprofen in terms of efficacy parameters: total area under pain relief to 4h (8.0±2.6 vs 8.3±2.7), total area under pain relief to 8h (22.4±4.6 vs 23.0±4.4), sum of pain intensity difference to 4h (-5.7±1.9 vs -6.0±2.0), sum of pain intensity difference to 8h (-17.5±3.3 vs -17.8±3.5), peak pain relief to 4h (3.4±0.8 vs 3.5±0.8), peak pain relief to 8h (3.9±0.5 vs 3.9±0.4), peak pain intensity difference to 4h (-2.6±0.7 vs -2.7±0.7), peak pain intensity difference to 8h (-3.3±0.6 vs -3.3±0.6). Total medication consumption, a requirement of rescue medication and global evaluation of efficacy were comparable in both groups. The incidence of adverse effect was also similar in both groups. CONCLUSIONS: Lornoxicam appears to be a new therapeutic agent for the treatment of primary dysmenorrhea.

Evaluation of cardioprotective effect of aqueous extract of Garcinia indica Linn. fruit rinds on isoprenaline-induced myocardial injury in Wistar albino rats.

In the present study, cardioprotective effect of aqueous extract of Garcinia indica Linn. fruit rinds in isoprenaline-induced myocardial infarction in Wistar albino rats was evaluated. In vitro total phenolic, total flavonoid content and 2, 2'-diphenyl-1-picrylhydrazyl hydrate radical scavenging activity was measured. In vivo effect of aqueous extract of G. indica was evaluated in Wistar albino rats by isoprenaline-induced myocardial injury model. Thirty six rats were randomly divided in 6 groups. Rats were treated with G. indica 250 mg/kg and 500 mg/kg doses for 21 days and myocardial injury was produced by subcutaneous injection of isoprenaline 85 mg/kg on day 20 and 21. Carvedilol 1 mg/kg for 21 days served as active control. Electrocardiogram parameters, cardiac injury markers (serum troponin-I, uric acid, lactate dehydrogenase, creatinine kinase-MB, aspartate aminotransferase and alanine aminotransferase), oxidative stress markers (superoxide dismutase, catalase and malondialdehyde level) and histopathological changes were evaluated in each group and compared using appropriate statistical tests. In vitro evaluation of aqueous extract showed significant antioxidant property. Isoprenaline produced significant myocardial ischemia as compared to normal control group (P<0.05). Administration of G. indica in both the doses did not significantly recover the altered electrocardiogram, cardiac injury markers, oxidative stress markers and histopathological myocardial damage as compared to disease control group (P>0.05). The aqueous extract of G. indica was not found to be cardioprotective against myocardial injury. Further study with more sample size and higher dose range may be required to evaluate its cardioprotective effect.

Drug-induced anaphylactic reactions in Indian population: A systematic review.

BACKGROUND: Epidemiological data on drug-induced anaphylactic reactions are limited in India and are largely depending on studies from developed countries. AIM: The aim was to analyze the published studies of drug-induced anaphylaxis reported from India in relation with causative drugs and other clinical characteristics. MATERIALS AND METHODS: The electronic databases were searched for Indian publications from 1998 to 2013 describing anaphylactic reactions. The information was collected for demographics, set up in which anaphylaxis occurred, causative drugs, incubation period, clinical features, associated allergic conditions, past reactions, co-morbid conditions, skin testing, IgE assays, therapeutic intervention and mortality. Reactions were analyzed for severity, causality, and preventability. Data were extracted and summarized by absolute numbers, mean (95% confidence interval [CI]), percentages and odds ratio (OR) (95% CI). RESULTS: From 3839 retrieved references, 52 references describing 54 reactions were included. The mean age was 35.31 (95% CI: 30.52-40.10) years. Total female patients were 61.11%. Majority reactions were developed in perioperative conditions (53.70%), ward (20.37%) and home (11.11%). The major incriminated groups were antimicrobials (18.52%), nonsteroidal antiinflammatory drugs-(NSAIDs) (12.96%) and neuromuscular blockers (12.96%). Common causative drugs were diclofenac (11.11%), atracurium (7.41%) and ß-lactams (5.96%). Cardiovascular (98.15%) and respiratory (81.48%) symptoms dominated the presentation. Skin tests and IgE assays were performed in 37.03% and 18.52% cases, respectively. The fatal cases were associated with complications (OR =5.04; 95% CI: 1.41-17.92), cerebral hypoxic damage (OR =6.80; 95% CI: 2.14-21.58) and preventable reactions (OR =14.33; 95% CI: 2.33-87.97). CONCLUSION: Antimicrobials, NSAIDs, and neuromuscular blockers are common causative groups. The most fatal cases can be prevented by avoiding allergen drugs.

Cardiovascular abnormalities with single dose of tapentadol.

This case represents the development of dizziness, palpitation, tightness in chest, flushing, and tremor on consumption of a single dose of tapentadol (100 mg) for acute lower back pain. The patient was admitted in the intensive cardiac care unit for continuous monitoring. At admission, electrocardiogram showed tachycardia (140/min) along with ST segment elevation in second chest lead (V2). The patient was monitored and advised not to take further doses of tapentadol. He was discharged after 36 hours of admission. Tapentadol should be used cautiously in patients with cardiovascular diseases and receiving sympathomimetic drugs.

Interaction between rosuvastatin and rocuronium in rat sciatic-gastrocnemius nerve-muscle preparation.

PURPOSE: Long-term use of rosuvastatin may be associated with myotoxicity. Statins are one of the groups commonly found to be associated with neuromuscular weakness. The present study was designed to investigate the interaction between rosuvastatin and rocuronium in vivo by using a sciatic-gastrocnemius nerve-muscle preparation of rat. METHODS: In our study groups, animals received rosuvastatin 2 mg/kg for 14 and 28 days. Train of four (TOF) stimulation was applied to the sciatic nerve, and gastrocnemius muscle contractions were recorded in Wistar albino rats. Intravenous infusion of rocuronium was given until the twitch responses were abolished. We ultimately compared the effective dose required for a desired effect in 95% of the population (ED95), duration 25%, deep block, recovery index, and time for returning of TOF ratio to 0.9 between the active control and study groups. RESULTS: Chronic administration of rosuvastatin at a dose of 2 mg/kg for 28 days significantly reduced the ED95 of rocuronium as compared to the active control group. Deep block and duration 25% were increased by 3.5 and 2.5 times, respectively, compared to the active control group. The spontaneous recovery of neuromuscular block was delayed, as evidenced by the prolonged recovery index and increase in time required for a return of the TOF ratio to 0.9. CONCLUSION: The neuromuscular blocking potency of rocuronium is increased and recovery is delayed in rats that pre-treated with rosuvastatin.

Drug utilization pattern and pharmacoeconomic analysis in geriatric medical in-patients of a tertiary care hospital of India.

OBJECTIVE: To evaluate drug utilization pattern in terms of defined daily dose along with pharmacoeconomic analysis in geriatric patients admitted in medical ward of a tertiary care hospital. MATERIALS AND METHODS: Retrospective medical record analysis was performed for indoor cases of the geriatric patients (age ≥65 years) admitted in medicine ward from January 2010 to December 2010 were analyzed for demographics, indications for admission, various systems involved, duration of hospital stay, various drugs prescribed, and adverse drug reaction. The drugs were categorized by anatomical therapeutic classification and defined daily dose was calculated. The World Health Organization prescribing indicators were assessed. Cost of the drugs was calculated to assess the economic burden. RESULTS: Cardiovascular diseases were the common cause for admission. Antiplatelet drugs-B01AC (93%), H2 blockers-A02BA (77.22%), antiemetics-A03FA (67.6%), vasodilators-C01D (55%), and hypolipidemic drugs-C10AA (52%) were commonly utilized groups. Average number of drugs per patient was 9.37 (95% CI: 9.09-9.64). Average number of antimicrobials prescribed per patient was 0.91 (95% CI: 0.82-0.99). Cefotaxime was the commonly prescribed antimicrobial drug. Average cost of treatment was ₹540.5 (95% CI: ₹458.0-623.0). Patients shared 45% of the economic burden for prescribed medicines. The average economic burden for drugs was significantly higher in expired than survived patients (₹749.49 vs. 457.59). CONCLUSION: Polypharmacy and irrational use of medicines are common problems in geriatric prescription. Prescription guidelines should be formatted for them.

Lathyrism: has the scenario changed in 2013?

Lathyrism is now rarely seen as a clinical disease in general, medical or neurology outpatient departments, throughout the world. Eating patterns of seeds of Lathyrus sativus are still prevalent focal points in parts of the world. Question arises, why are we not seeing cases of lathyrism? Is it that the disease has changed its profile, with the changing socioeconomic status of the poor or underdeveloped or moderately developed countries? Is it that the seeds of lathyrus are less toxic now? Is it that the body defence against toxins of lathyrus has genetically modified? To find out answers to these interesting questions, an extensive questionnaire-based sampling was done among 1000 subjects from northern India to identify the human behaviour regarding the knowledge, attitude, and practices (KAPs) for L. sativus. Four clinically suspected cases of Lathyrism were also fully worked up. It was concluded that many areas of India are still being fed with lathyrus seeds, but not many cases have appeared. Many questions have to be answered, as to what has reduced the incidence of lathyrism.

Evaluation of anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits.

This study investigated the possible anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits in selected experimental animal models. Anti-inflammatory activity of Pedalium murex Linn., with doses of 200 mg/kg and 400 mg/kg, p.o., was evaluated by Lambda-carrageenan induced paw oedema in Wistar albino rats; analgesic activity with doses of 280 mg/kg and 560 mg/kg, p.o., was evaluated by hot plate method and acetic acid induced writhing method in Swiss albino mice; and antipyretic activity with doses of 110 mg/kg and 220 mg/kg, p.o., was evaluated in New Zealand white rabbits by injecting gram -ve lipopolysaccharide obtained from E. coli. Results were analysed by one way ANOVA followed by Dunnet's multiple comparison test. Pedalium murex Linn. showed significant anti-inflammatory activity from 15 min to 180 min as compared to vehicle treated animals. It was comparable to diclofenac sodium at 180 min. The extract did not prolong the reaction time on hot plate method but significantly reduced the number of writhing after acetic acid administration. Also the extract did not show any antipyretic activity on lipopolysaccharide induced pyrexia. It is therefore concluded that the ethanolic extract of Pedalium murex Linn. fruits has an anti-inflammatory and peripheral analgesic effects.

Effect of Zidovudine and its interaction with rocuronium on neuromuscular transmission.

Neuromuscular weakness is often found in patients receiving zidovudine therapy due to mitochondrial damage. Effect of zidovudine was evaluated in indirectly and directly stimulated isolated rat phrenic nerve hemidiaphragm preparations, by cumulative dose response curve with square wave pulses, 0.5 ms duration of 2 Hz at every 10 s. To understand the observed effect of zidovudine, interaction studies were carried out with rocuronium. Dose response curve of rocuronium was compared in the absence and in the presence of 1.2 and 12 mmol/ml zidovudine. In another set of experiment, intact animals were treated with zidovudine 50 and 100 mg/kg for 15 days and phrenic nerve hemidiaphragm was obtained for in vitro experiment. Effect of zidovudine (30 mmol/ml) on twitch responses inhibited by dantrolene 50 µmol/ml, magnesium chloride 8 mmol/ml, rocuronium 10 µmol/ml, succinylcholine 25 µmol/ml and lignocaine 600 µmol/ml was studied. Zidovudine (3-30 mmol/ml) significantly augmented the twitch responses up to 80 and 40% in indirectly and directly stimulated preparations, respectively (P<0.05). Zidovudine did not show significant interaction with rocuronium in any group as per dose response curve and inhibitory concentration 5%, inhibitory concentration 50% and inhibitory concentration 95% of rocuronium. Zidovudine (30 mmol/ml) augmented the twitch responses inhibited by dantrolene, magnesium chloride and rocuronium. It reduced the time for complete block of succinylcholine (P<0.05). Zidovudine affects the neuromuscular transmission. No conclusive interaction between rocuronium and zidovudine was found.

Anti-urolithiatic effect of cow urine ark on ethylene glycol-induced renal calculi.

PURPOSE: To investigate the anti-urolithiatic effect of cow urine ark (medicinal distilled cow urine) on ethylene glycol (EG) induced renal calculi. MATERIALS AND METHODS: 36 male Wistar rats were randomly divided into 6 equal groups. Group I animals served as vehicle control and received distilled water for 28 days. Group II to VI animals received 1% v/v EG in distilled water for 28 days. Group II served as EG control. Group III and IV (preventive groups) received cow urine ark orally for 28 days in doses of 1 mL/kg and 2 mL/kg, respectively. Group V and VI (treatment groups) received 1 mL/kg and 2 mL/kg cow urine ark orally, respectively from 15th to 28th days. 24-hour urine samples were collected on day 0 and 28. Urine volume and oxalate levels were measured. On day 28, blood was collected for biochemical parameters. Animals were sacrificed and kidneys were harvested, weighed and histopathologically evaluated for calcium oxalate (CaOx) crystals. To calculate the percentage of inhibition of mineralization, simultaneous flow static in-vitro model was used. RESULTS: EG significantly increased urine oxalate, serum creatinine, blood urea level; kidney weight and CaOx deposits. Provision of cow urine ark resulted in significantly lower levels of urine oxalate, serum creatinine, blood urea and CaOx depositions as compared to Group II. (p value < 0.05) It also significantly restored kidney weight. (p value < 0.05) Cow urine ark inhibited 40% and 35% crystallization of CaOx and calcium phosphate, respectively. CONCLUSION: Cow urine ark is effective in prevention and treatment of EG induced urolithiasis in Wistar rats.

Nevirapine and/or co-trimoxazole induced Stevens Johnson syndrome in HIV infected patient--a case report.

A 46 years old HIV reactive patient developed Stevens Johnson syndrome (SJS) probably due to nevirapine and/or co-trimoxazole. Patient was on zidovudine + lamivudine + nevirapine along with Co-trimoxazole since last two months. After 15 days, zidovudine was replaced with stavudine due to development of anemia. All these drugs were stopped after development of reaction. Temporal association was found between stavudine, lamivudine, nevirapine, cotrimoxazole and development of the reaction. Nevirapine and Co-trimoxazole were suspected to cause this reaction most probably due to associated hepatotoxicity and their common potential to cause SJS. In our case, patient died despite stopping of all medications.

Neuromuscular blocking effect of fluoxetine and its interaction with rocuronium.

As selective serotonin reuptake inhibitors have an inhibitory effect on nicotinic acetylcholine receptors, they may affect the neuromuscular transmission and interact with neuromuscular blockers. This study was designed to observe the effect of fluoxetine on neuromuscular transmission and its interaction with rocuronium using the rat phrenic nerve hemidiaphragm and rabbit head drop methods. Rat phrenic nerve hemidiaphragms were mounted and stimulated using a train of four pulses (TOF). The effect of fluoxetine was studied on both indirectly and directly stimulated basal twitch responses by plotting cumulative dose response curves (DRCs). DRCs of rocuronium were obtained in the absence, and presence of 5 µm and 20 µm fluoxetine to study its interaction. ED5 , ED50 and ED95 values of rocuronium DRCs in absence and presence of fluoxetine were calculated. Fluoxetine significantly inhibited twitch responses in both indirect and directly stimulated preparations. Fluoxetine (20 µm) caused an increase in the potency of rocuronium such that the ED50 and ED95 values of rocuronium DRCs were significantly decreased. Partially inhibited twitch responses by fluoxetine (100 µm) were not reversed by neostigmine (3.3 µm) or 3,4 diaminopyridine (0.25 µm). Rabbits were given fluoxetine 0.25 mg kg(-1) and 1 mg kg(-1) orally for 15 days, and on 15th day, rocuronium infusion was given, and time for head drop was recorded. The time of head drop was significantly reduced in fluoxetine pretreated as compared to control group. Fluoxetine blocks the neuromuscular transmission and increases the potency of rocuronium-induced neuromuscular block.
