Thrombocytopenia in children with malaria–A study from coastal Karnataka,India

ObjectiveTo study the occurrence and severity of thrombocytopenia in children with malaria.MethodsIt was a retrospective study, done at Fr Muller Medical College Hospital Mangalore, in Karnataka, India. Data regarding all positive cases of malaria < 15 years admitted in the hospital between January 2010 to June 2011 were obtained. Patients were further assessed for thrombocytopenia and its severity. Data were analysed by Chi square test using SPSS version 13.0.ResultsA total of 159 cases were included in the study with a mean age of presentation of 9 years. Plasmodium vivax was identified in 106 (66%) patients while Plasmodium falciparum in 26 (16%) and mixed infection in 27 (18%) patients. Thrombocytopenia was observed in 113 (71%) cases, of which 35 (31%) cases had mild, 49 (43%) cases moderate and 29 (26%) cases had severe thrombocytopenia. Thrombocytopenia was equally found in vivax and falciparum infection with no significant difference in severity between vivax and falciparum species.ConclusionsThrombocytopenia is frequently seen in malaria and it is not dependent on type of malaria. In any acute febrile illness, thrombocytopenia should alert one to the possibility of malaria.     

Deaths among women of reproductive age: A forensic autopsy study

Unnatural deaths in women of reproductive age (range 12–49 years) have a serious psychological and social impact on the family and community. Deaths among women of reproductive age reported as medico-legal cases were investigated to see the trend in terms of cause and manner of death. The study group consisted of a series of 328 consecutive forensic autopsies on women in the reproductive age group, performed between 2009 and 2011 at the Government Wenlock District Hospital, Mangalore, India by qualified specialist forensic medicine experts. Unnatural deaths formed 93.6% of the cohort. The top three causes of death included burns, poisoning and hanging forming 69.5% of the cases. The manner of death was suicide in 45.4% cases, accident in 43.6% cases and homicide in 4.6% cases. The circumstances of death were related to alleged medical negligence in 2.4% cases. Death in 4% cases was natural mannered with a disease being the cause of death. Three-fourths of the victims were married. Married women formed 63.1% of the suicidal victims. Homicidal deaths were not reported among unmarried women. The preponderant method of suicide was by poisoning at 42.3% (63 cases), followed by hanging (34.9%), burns (11.4%) and drowning (9.4%). These four methods comprised 98% of the total suicidal deaths in this study cohort. Accidental deaths were predominantly caused by burns (62.2%) and road traffic accident (23.1%). Two-thirds of the homicidal deaths were due to assault caused by blunt-force trauma, ligature strangulation and sharp-force trauma. One-third of the homicidal victims died due to burns. With a clear understanding of the cause and manner of death, it may be possible to predict, and hopefully prevent, future cases of unnatural deaths in women of reproductive age who form a very important group of society.

Preemptive analgesia for postoperative pain relief in lumbosacral spine surgeries: a randomized controlled trial.

BACKGROUND CONTEXT: Administration of analgesic medication, before the actual onset of painful stimulus, is more effective than that after the onset of painful stimulus. This is the principle of preemptive analgesia. Although it is often considered superior to other forms of analgesia, its role in postoperative pain relief after lumbosacral spinal surgery has not been fully investigated. PURPOSE: To analyze the efficacy of preemptive analgesia with a single caudal epidural injection for patients undergoing surgeries on the lumbosacral spine by the posterior approach. STUDY DESIGN/SETTING: Randomized, double-blinded and controlled clinical trial. PATIENT SAMPLE: Eighty-two patients who underwent discectomy in the lumbosacral spine by the posterior approach, with or without instrumentation, were randomized to the control group (n=40) and to the study group (n=42). METHODS: Patients in control group received a single caudal epidural injection of 20 ml of normal saline. Patients in study group received a single caudal epidural injection of 20 ml containing bupivacaine and tramadol as the active agents. The time interval between this injection and the surgical incision was never less than 20 minutes in either of the groups. This facilitated enough time for the drug to get fixed to the nerve roots, leading to effective preemptive analgesia. OUTCOME MEASURES: Patients were monitored for postoperative pain immediately after surgery when they had completely recovered and regained consciousness from general anesthesia, and subsequently 4, 8, 12 and 24 hours thereafter. Pain was quantified using the visual analog scale (VAS) and the verbal rating scale (VRS). The time at which supplemental analgesic medication was first demanded in the postoperative period by the patient was also noted. RESULTS: The two groups were comparable for age, sex, body weight and the type of surgery they underwent. Because the data did not have a normal Gaussian distribution, the one-tailed Mann-Whitney test, being a nonparametric test, was adopted for statistical analysis. Accordingly, VAS and VRS values at all time intervals were significantly lower (p<.0001) in the study group as compared with the control group. This indicated significantly better pain relief in the study group. There was also a significant delay (p=.0041) in the first demand for supplemental analgesic medication in the postoperative period in the study group. No complication specific to the procedure was noted except for the development of postoperative urinary retention, which was transient and appropriately managed with urinary catheterization. CONCLUSIONS: Preemptive analgesia with a single caudal epidural injection of bupivacaine and tramadol is a safe, simple and effective method for postoperative pain relief.     

Spinal muscular atrophy with respiratory distress syndrome (SMARD1): Case report and review of literature

Spinal muscular atrophy with respiratory distress syndrome (SMARD1) is a rare cause of early infantile respiratory failure and death. No cases have been currently described from India. Two low-birth-weight infants presented prior to 6 months of age with recurrent apnea and respiratory distress. Both required prolonged ventilation, and had distal arthrogryposis and diaphragmatic eventration. Nerve conduction study revealed motor sensory axonopathy. Genetic testing confirmed mutations in immunoglobulin mu binding protein (IGHMBP2). These two cases establish presence of SMARD1 in our population. Both infants died on discontinuation of ventilation. Antenatal diagnoses done in one pregnancy. Though rare, high index of suspicion is essential in view of poor outcome and aid antenatal counseling.     

Bioavailable vitamin D is more tightly linked to mineral metabolism than total vitamin D in incident hemodialysis patients

Prior studies showed conflicting results regarding the association between 25-hydroxyvitamin D (25(OH)D) levels and mineral metabolism in end-stage renal disease. In order to determine whether the bioavailable vitamin D (that fraction not bound to vitamin D-binding protein) associates more strongly with measures of mineral metabolism than total levels, we identified 94 patients with previously measured 25(OH)D and 1,25-dihydroxyvitamin D (1,25(OH)(2)D) from a cohort of incident hemodialysis patients. Vitamin D-binding protein was measured from stored serum samples. Bioavailable 25(OH)D and 1,25(OH)(2)D were determined using previously validated formulae. Associations with demographic factors and measures of mineral metabolism were examined. When compared with whites, black patients had lower levels of total, but not bioavailable, 25(OH)D. Bioavailable, but not total, 25(OH)D and 1,25(OH)(2)D were each significantly correlated with serum calcium. In univariate and multivariate regression analysis, only bioavailable 25(OH)D was significantly associated with parathyroid hormone levels. Hence, bioavailable vitamin D levels are better correlated with measures of mineral metabolism than total levels in patients on hemodialysis.
