ABSTRACT

Experience sampling methodologies are likely to play an important role in advancing our understanding of momentary influences on aggression, including short-term antecedent psychological states and situations. In this study, we evaluate whether a newly developed experiencing sampling measure of aggression, the Aggression Experience Sampler (Aggression-ES), provides a valid and reliable measure of aggression in experience sampling contexts. Participants were a convenience sample of 23 young adults recruited from the local University community. Data were collected using an experience sampling smartphone application over 8 days. They were analyzed using multilevel structural equation modeling. Our results support the within- and between-person reliability and the criterion validity of the Aggression-ES. The Aggression-ES represents a good choice of measure for use in experience sampling studies of aggression. Further work in other samples will help to provide further validity evidence for the measure.

ABSTRACT

BACKGROUND AND AIM: Nalbuphine as an adjuvant intrathecally can produce significant analgesia with minimal side effects. However, no research has been done with isobaric ropivacaine. We, therefore, in this prospective, randomised double-blind study tried to find the optimal dose of intrathecal nalbuphine with isobaric 0.75% ropivacaine for elective lower limb surgeries. MATERIALS AND METHODS: One hundred American Society of Anaesthesiologists I and II patients undergoing elective lower limb surgery were divided into four groups randomly: groups A, B, C and D, who received 0.5 mL normal saline or 0.4, 0.8 and 1.6 mg nalbuphine made up to 0.5 mL normal saline added to 22.5 mg (total volume 3.5 mL) isobaric 0.75% ropivacaine, respectively. The onset of sensory and motor block, two-segment regression time, duration of sensory and motor block, Visual Analogue Scale (VAS) and the incidence of adverse effects were compared between the groups. RESULTS: The onset of both sensory and motor blockade was faster with addition of 0.4, 0.8 and 1.6 mg of nalbuphine when compared with ropivacaine alone; however, it was not statistically significant (P > 0.05). Two-segment regression time and duration of analgesia and motor blockade were highest with 1.6 mg of nalbuphine followed by 0.8, 0.4 and plain 0.75% ropivacaine (P < 0.05). The duration of sensory blockade in all four groups was slightly more than the duration of motor blockade. VAS readings were comparable in all nalbuphine groups when compared with ropivacaine group. Haemodynamic variability among the four groups was comparable. Incidence of adverse effects was highest in the 1.6-mg group when compared with others, although it was statistically insignificant (P > 0.05). CONCLUSION: Nalbuphine can be a good alternative to other opioids as an adjuvant intrathecally to prolong postoperative analgesia with a minimal side effect profile. Addition of nalbuphine to isobaric 0.75% ropivacaine gives the added advantage of significant analgesia with early motor recovery. We infer from our study that when compared with 1.6 mg of nalbuphine, both 0.4 and 0.8 mg nalbuphine are equally good as adjuvants to isobaric 0.75% ropivacaine in elective lower limb surgeries with prolonged analgesia, a reliable block with equal efficacy but with lesser side effects.

ABSTRACT

Scrub typhus and malaria can involve multiple organ systems and are notoriously known for varied presentations. However, clinical malaria or scrub typhus is unusual without fever. On the other hand, altered sensorium with or without fever, dehydration, hemorrhage and hemolysis may lead to low blood pressure. Presence of toxic granules and elevated band forms in such patients can even mimic sepsis. When such a patient is in the peripartum period, it creates a strong clinical dilemma for the physician especially in unbooked obstetric cases. We present such a case where a 26-year-old unbooked female presented on second postpartum day with severe anemia, altered sensorium, difficulty in breathing along with jaundice and gum bleeding without history of fever. Rapid diagnostic test for malaria was negative and no eschar was seen. These parameters suggested a diagnosis of HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet) syndrome with or without puerperal sepsis. Subsequently she was diagnosed as having asymptomatic malaria and scrub typhus and responded to the treatment of it. The biochemical changes suggestive of HELLP syndrome also subsided. We present this case to emphasize the fact that mere absence of fever and eschar does not rule out scrub typhus. It should also be considered as a differential diagnosis in patients with symptoms and signs suggesting HELLP syndrome. Asymptomatic malaria can complicate case scenario towards puerperal sepsis by giving false toxic granules and band form in such situations.
