Study DesignThe study was conducted on patients who received autologous conditioned serum (ACS) as a line of treatment at the Orthopedics outpatient department of Post Graduate Institute of Medical Education and Research (PGIMER, Chandigarh) from January 2011 to June 2012. Of the 1,224 patients, 20 males or females were included in the study based on the inclusion and exclusion criteria. The institutional board of PGIMER approved the study before it was initiated.PurposeTo study the efficacy of ACS in the treatment of unilateral lumbar radiculopathy.Overview of LiteratureInterleukin (IL)-1 appears to be of special importance among the cytokines identified in orthopedic diseases. ACS contains high concentrations of IL-1 receptor antagonist, antagonist to IL-1 in that is a biochemical 'sensitizer' of nerve roots in radiculopathy.MethodsWe included 20 patients with unilateral lumbar radiculopathy after obtaining informed consent. We prepared ACS as described by Meijer et al. Under bi-planar fluoroscopic imaging in anterior-posterior and lateral views, ACS was administered via epidural perineural technique. Patients in both groups were evaluated by quadruple visual analogue scale, straight leg raising test, revised Oswestry disability index, and 12-Item Short Form of Health Survey before and after epidural injections at 3 weeks, 3 months, and 6 months.ResultsThere was a statistically significant change in all parameters from pre-injection to first, second, and third follow-up (p

Aim: Report of 125 pediatric patients of empyema thoracis treated by open decortication, highlighting the presentation, delay in referral, operative findings, the response to surgical intervention and follow-up. Materials and Methods: All the children who underwent open decortication for stage III empyema thoracis during the study period were included. Preoperative workup included hemogram, serum protein, chest radiographs and contrast-enhanced computed tomographic (CECT) scan of the chest. Results: One hundred and twenty-five patients (81 males, 44 females) (age 3 months-12 years, mean 4.9 years) were operated during a 4.5-year period. Among them, two children underwent bilateral thoracotomies. Also, 81.6% patients were referred 3 weeks after the onset of disease (mean duration 9 weeks). Intercostal chest drainage (ICD) had been inserted in (119) 95% cases. Thickened pleura, multiloculated pus and lung involvement were invariably seen on CECT scan. Bronchopleural fistula was present in 10 patients and empyema necessitatis in 2. Decortication, removal of necrotic tissue and closure of air leaks was performed in all the patients. Necrotizing pneumonia was seen in (35) 27.5% cases. Mean duration of postoperative ICD was 7 days. Follow-up ranged from 3 months to 4 years (mean 12 months). There was no mortality. Six patients had proven tuberculosis. Conclusions: The duration of the disease had a direct relationship with the thickness of the pleura and injury to the underlying lung. Delayed referral causes irreversible changes in the lung prolonging recovery. Only 18% presented within the early period of the disease. Meticulous open surgical debridement gives gratifying results. The status of the lung at the end of surgery is a major prognostic factor.

Aim: To assess the changes in urethral morphology 3 months post fulguration of posterior urethral valves (PUVs) on micturating cystourethrogram (MCUG) and correlate these changes with the overall clinical status of the patient. Materials and Methods: A total of 217 children, managed for PUVs during a period of 6 years in a single surgical unit were prospectively studied. The ratio of the diameters of the prostatic and bulbar urethras (PU/BU) was calculated on the pre- and post-fulguration MCUG films. They were categorized into three groups based on the degree of normalization of posterior urethra (post-fulguration PU/BU ratio). Results: Group A: Of the 133 patients, 131 had normal urinary stream and 4 (3%) had nocturnal enuresis. Vesicoureteral reflux (VUR), initially seen in 83 units (31% units), regressed completely at a mean duration of 6 months in 41 units (49%). Of the 152 non-VUR, hydroureteronephrosis (HUN) units, 11 were poorly functioning kidneys. Persistent slow but unobstructed drainage was seen in 23 units (16%) over a period of 1.5-5 years (mean 2.5 years). Group B: All the 11 patients had a normal stream. Four (36.4%) had daytime frequency for a mean duration of 1 year and one (9%) had nocturnal enuresis for 1 year. Grade IV-V VUR was seen in five patients (three bilateral), which regressed completely by 3 months in five units (62.5%). In the non-VUR, HUN patients, slow (but unobstructed) drainage was persistent in two units (14%) at 3 years. Group C: Of the 16 patients, only 5 (31.3%) were asymptomatic. Six patients (nine units) had persistent VUR for 6 months to 3 years. Of the 20 units with HUN, 17 (85%) were persistent at 1-4 years (mean 2 years). Eight patients (50%) required a second fulguration while 3 (18.7%) required urethral dilatation for stricture following which all parameters improved. Conclusions: Adequacy of fulguration should be assessed by a properly performed MCUG. A postop PU/BU ratio >3 SD (1.92) should alert to an incomplete fulguration or stricture. Patients within normal range ratio have faster recovery of slow draining units, reflux and less voiding dysfunction. There is a strong correlation between incomplete fulguration and persistent slow draining units, uremia, voiding dysfunction and urinary tract infections.

Thirty patients undergoing closed mitral valvotomy were prospectively randomised to receive either thoracic or lumbar epidural catheter. General anaesthesia consisted of morphine sulphate 0.15 mg/kg (single dose given before skin incision), thiopentone sodium 4-6 mg/kg, vecuronium and halothane titrated to stable haemodynamics. In the immediate postoperative period, pain was assessed by VAS (visual analogue scale) and VRS (verbal ranking score) and an epidural fentanyl bolus of 1.5 microg/kg was given followed by an infusion of 0.4 microg/kg/hr. Pain was assessed after 30 min and if pain relief was still inadequate, another fentanyl bolus of 1 microg/kg was administered, followed by an increase in infusion rate to 0.6 microg/kg/hr. If two consecutive pain scores were satisfactory (VAS

Byline: Y. Batra, D. Kanjilal Formation of controlled semiconductor nanostructures on and near the surface region using dense electronic excitation produced by high energy heavy ions has been reviewed. Various parameters of the energetic ion beams such as energy, species and beam current can be controlled to have desired size. Results of new initiatives on production of Ge nanostructures of desired size by high-energy heavy ions are discussed. GeOx films were irradiated by 100 MeV gold (Au) ions. Formation of Ge nanostructures was studied by various techniques like micro Raman, Fourier transform infrared spectroscopy (FTIR), glancing incident X-ray diffraction (GIXRD), transmission electron microscopy (TEM), high resolution electron microscopy (HREM), atomic force microscopy (AFM), elastic recoil detection analysis (ERDA), magnetic force microscopy (MFM) and magnetisation measurements. Development of Ge nanostructures is explained on the basis of phase separation of GeOx and controlled crystallisation of Ge in the nanometre scale taking place around the trajectory of the swift heavy ion. Nanostructures are formed in a controlled manner by dense electronic excitation due to melting and subsequent fast cooling of the region along the trajectories of the energetic ions.

This randomised, double-blind study was designed to compare the duration of analgesia and adverse effects following intrathecal administration of dexmedetomidine or clonidine, both with bupivacaine, in trauma patients. Ninety adult trauma patients of American Society of Anesthesiologists physical status I-II, scheduled for lower limb surgery under subarachnoid block, were randomly allocated to one of three groups. All groups received hyperbaric bupivacaine 0.5% 3 ml, to which was added saline 0.5 ml (Group B): clonidine 50 µg (Group C) or dexmedetomidine 5 µg (Group D). The onset and duration of sensory and motor blockade, severity of postoperative pain, time to first rescue analgesia and total analgesic requirement for 24 hours were noted. There was no significant difference in the onset time of the block but the duration of sensory and motor blockade was prolonged in Groups C and D, compared with Group B. The time to analgesia was significantly prolonged in Group D (824±244 minutes) compared with Group C (678±178 minutes; P=0.01), the latter being longer than Group B (406±119 minutes; P=0.0001). Postoperative pain scores were lower in Groups C and D compared with group b. The requirement for rescue analgesia during the first 24 postoperative hours was significantly less in Groups C and D as compared to Group B (P=0.0001), but comparable between Groups C and D (P=0.203). In conclusion, dexmedetomidine 5 µg added to intrathecal bupivacaine 15 mg produces longer postoperative analgesia than clonidine 50 µg among trauma patients undergoing lower limb surgery.
