RESUMO
Objective: To compare the efficacy of daily assisted physicalexercise (starting from one week of postnatal age) on bonestrength at 40 weeks of post menstrual age to no intervention ininfants born between 27 and 34 weeks of gestation.Design: Open-label randomized controlled trial.Setting: Tertiary-care teaching hospital in northern India from 16May, 2013 to 21 November, 2013.Participants: 50 preterm neonates randomized to Exercisegroup (n=26) or Control group (n=24).Intervention: Neonates in Exercise group underwent onesession of physical exercise daily from one week of age, whichincluded range-of-motion exercises with gentle compression,flexion and extension of all the extremities with movements ateach joint done five times, for a total of 10-15 min. Infants inControl group underwent routine care and were not subjected toany massage or exercise Outcome measures:Primary: Bone speed of sound of lefttibia measured by quantitative ultrasound at 40 weeks postmenstrual age. Secondary:Anthropometry (weight length andhead circumference) and biochemical parameters (calcium,phosphorus, alkaline phosphatase) at 40 weeks post menstrualage.Results:The tibial bone speed of sound was comparablebetween the two groups [2858 (142) m/s vs. 2791 (122) m/s;mean difference 67.6 m/s; 95% CI - 11 to 146 m/s; P=0.38]. Therewas no difference in anthropometry or biochemical parameters.Conclusion:Daily assisted physical exercise does not affectthe bone strength, anthropometry or biochemical parameters inpreterm (27 to 34 weeks) infants.
RESUMO
Objective: To compare phototherapy devices based on their physical and photo-biological characteristics viz spectral properties, maximum and mean irradiance, treatable percentage of body surface area, decay of irradiance over time and in vitro photoisomerisation of bilirubin. Design: In vitro experimental study. Setting: Ocular pharmacy laboratory at a tertiary care hospital. Methodology: All the characteristics were measured at a fixed distance of 35 cm from one compact fluorescent lamp (CFL) and three light emitting diode (LED) phototherapy devices in a dark room with an irradiance of <0.1μW/cm2/nm. Estimation of products of in vitro photoisomerisation was done using liquid chromatography - tandem mass spectroscopy (LC-MS/ MS). Results: The emission spectral data were comparable between the phototherapy devices. The devices, however, differed in their maximum irradiance with the spot and indigenous LED units having the highest and lowest values, respectively (56.5 and 16.8μW/cm2/nm). The mean irradiance – measured in 5x5cm grids falling within the silhouette of a term baby – of the spot and improvised LED devices were low (26.8μW/cm2/nm and 11.5μW/cm2/ nm, respectively) possibly due to unevenness in the irradiance of light falling within the silhouette. There was a significant difference in the amount of bilirubin left after exposure to light over a 2-hour time period (% reduction of bilirubin) among the four devices (P=0.001); at 120 minutes after exposure, the amount of bilirubin left was lowest for the CFL (16%) and spot LED (17%) devices and highest for the indigenous LED unit (41%). Conclusions: The four phototherapy devices differed markedly in their physical and photobiological characteristics. Since the efficacy of a device is dependent not only on the maximum irradiance but also on the mean irradiance, rate of decay of irradiance, and treatable surface area of the foot print of light, each phototherapy device should have these parameters verified and confirmed before being launched for widespread use.
RESUMO
We report a child with acute lymphoblastic leukemia who developed primary cutaneous mucormycosis at the site of lumbar puncture during induction chemotherapy. Though high mortality rates are reported with invasive mucormycosis, prompt biopsy, early identification and antifungal therapy using a combination regime of amphotericin-B and rifampicin along with extensive surgical debridement led to complete cure of the lesions in the index case.
