Objective: To evaluate the outcome of upper ureteric stone management using semirigid URS + ICPL. Materials and Methods: Patients undergoing URS + ICPL in patient department were included in the study. Total 38 patient were included in the study from March 2009 to June 2010 in National Institute of Kidney diseases & Urology, Dhaka. Stone size was 8 mm to 1.5 cm, patients were with good renal function, well excreation on both side, without any distal obstruction, infection or multiple ureteric calculi. The procedure was done under SAB.Cystoscopy was done for identification of ureteric orifice and guide wire was passed within ureteric orifice under visual monitoring.46 cm 10 Fr Storz Uretroscope was advanced next to the guide wire.At time a tortuous portion of the ureter was encountered a second guide wire was helpful. As soon as the stone was seen the pneymatic probe was pushed toward the stone.After fixing to the stone, pneumatic source was on and stone fragmentation was started. Care was taken to avoid injury of the ureter and keeping eye one stone fragment migration within the ureter was achieved. Placement of D-J stent was done at the conclusion of the procedure in most of the cases Result: The patients were followed upto 3 months post-operatively. Within immediate complications fever occured in 10 (26.3%) patients, severe haematurea occured in 8 (21.3%) patients, ureteral injury in 8 (21.3%) & ureteric perforation in 2 (4.8%) patients underwent URS+ ICPL. Stone clearance rate after 01 month of intervention was 30 (78.9%). Almost half of the patients developed UTI after 01 month of intervention. Pyelonephritis occured in 2 ( 4.8%) patient in this group. After 03 months of intervention 84.2% patients exibited complete clearance of stone. Only 02 (4.8%) patients developed ureteric stricture. Conclusion: For management of selective sized upper ureteric stone ureterorenoscopy with semirigid one using pneumatic source of energy is a good option for it’s high stone clearance & resonably low complications.

Objective: To measure the accuracy of a novel device in detecting Bradycardia andDesaturation (B&D) events and to determine its efficacy in resolving apneas innewborns with comparison to standard monitor (which only detects B&D eventsand alerts).Design: This was a prospective observational study.Setting: Sick Newborn Care Unit of a large tertiary referral hospital in Hyderabad,India.Methods: 31 newborns were provided with a novel device, which monitored oxygensaturation and pulse rate and alarmed when values dropped below a set thresholdwhich is referred as an event, henceforth. The novel device also provided footstimulation in response to above-mentioned events. When the monitor alarmed, anurse attended to the baby to confirm whether the baby was breathing and whetherthe event had been resolved by the device. If the event had not resolved, appropriateaction as per the standard-of-care was performed.Results: The novel device “ApneBootTM” positively detected B&D events 94.03% oftimes as compared to the standard reference monitor. 56 of 67 observed B&D eventswere visually confirmed to be apneas, indicating that 83.6% of B&D eventscoincided with apneas. Of the 56 apneic events, 50 were central apneas, of which 35were resolved by the novel device, making the device’s efficacy of apnea resolution70%.Conclusion: The results of the study indicate that this novel device “ApneBootTM”is very effective in detecting and alarming B&D events, which coincides with theapnea, and resolving it by providing foot stimulation.Keywords: Novel Device, Neonatal Apnea, Low Birth Weight, Body Temperature,Kangaroo Mother Care, Community Health,

BACKGROUND “Short-term” samples are not the most appropriate for reflecting Chronic Cortisol Concentration (CCC). Although hair is used for reflecting the systemic cortisol level over “long-term”, its use appears clinically problematic. Local stress and non-stress related factors may release a circumscribed cortisol secretion that is accumulated in hair. Non-stressful earwax extraction methods may provide a more accurate specimen to measure CCC. OBJECTIVE Correlate cortisol levels using hair, serum and earwax samples METHODS Earwax from both ears of 37 controls were extracted using a clinical procedure commonly associated with local pain. One month later, earwax from the left ear side was extracted using the same procedure, and earwax from the right ear side was comfortably extracted, using an earwax self-sampling device. Participants also provided one centimetre of hair that represented the retrospective month of cortisol output, and one serum sample that reflected the effect of systemic stressors on cortisol levels. Earwax (ECC), Hair (HCC) and Serum (SCC) Cortisol Concentration were correlated and compared. Confounders´ effect on cortisol levels were studied. RESULTS Serum showed the largest and hair the lowest cortisol concentration (p<0.01). Left-ECC was larger than Right-ECC (p=0.03). Right-ECC was the only sample unaffected by confounders (all p>0.05). Right-ECC and HCC showed the only significant association (r=0.39; p=0.03). CONCLUSIONS The self-sampling device did not represent a local stressor for the ceruminous glands. It provided the cortisol level with the least likely to be affected by confounding factors over the previous month. ECC using the novel device may constitute another accurate, but more suitable and affordable specimen for measuring CCC.

AbstractThe lactate threshold (LT1), which is defined as the first rise in lactate concentration during incremental exercise, has not been non-invasively and conveniently determined in a clinical setting. We aimed to visualize changes in lactate concentration in sweat during exercise using our wearable lactate sensor and investigate the relationship between the lactate threshold (LT1) and ventilatory threshold (VT1). Twenty-three healthy subjects and 42 patients with cardiovascular diseases (CVDs) were enrolled. During exercise, the dynamic changes in lactate values in sweat were visualized in real-time with a sharp continuous increase up to volitional exhaustion and a gradual decrease during the recovery period. The LT1 in sweat was well correlated with the LT1 in blood and the VT1 (r = 0.92 and 0.71, respectively). In addition, the Bland–Altman plot described no bias between the mean values (mean differences: − 4.5 and 2.5 W, respectively). Continuous monitoring of lactate concentrations during exercise can provide additional information for detecting the VT1.
