Kidney changes after extracorporeal shock wave lithotripsy: appearance on MR imaging

The occurrence of changes in the kidneys after extracorporeal shock wave lithotripsy (ESWL) was evaluated with magnetic resonance (MR) imaging in 34 patients, utilizing T1-weighted spin-echo pulse sequences. Five of the 34 patients underwent bilateral ESWL therapy before MR imaging. Of the 39 kidneys studied, 29 (74%) showed one or more changes on MR imaging: subcapsular or perinephric fluid (n = 10), focal (n = 16) or diffuse (n = 8) loss of the corticomedullary junction (CMJ), and focal areas of increased (n = 7) or decreased (n = 3) signal intensity. The CMJ changes were more prominent with increasing numbers of shock waves administered during the procedure. These relatively subtle changes detected on MR imaging may not be apparent with other imaging techniques. The long-term clinical significance of these findings is not yet known, although no apparent serious renal pathologic condition was detected.     

Serum interleukin-2 receptor in infants and young children

Soluble interleukin-2 receptor (IL-2R) concentrations were measured in 110 serum samples from 102 children undergoing routine small bowel biopsy for a wide range of gastrointestinal symptoms. Young children in the control group who had no gastrointestinal disease and a normal intestinal mucosa were found to have high concentrations of IL-2R. There was a significant inverse relationship between IL-2R concentration and age in the control group. Children with a gastrointestinal diagnosis appeared to have increased IL-2R concentrations, although some of the diagnostic groups were too small in size for statistical analysis. Children with cow's milk sensitive enteropathy had IL-2R concentrations equivalent to those of age-matched controls. High concentrations of IL-2R in young healthy children implies that serum IL-2R is of no clinical use as an index of inflammation in this age group.     

Pain management in mice using methanol extracts of three plants belongs to family Amaranthaceae

ObjectiveTo investigate the analgesic activity of methanolic extract of Amaranthus viridis (A. viridis), Amaranthus caudatus (A. caudatus) and Amaranthus spinosus (A. spinosus).MethodsIn this study, the analgesic activity of methanol extracts of all three plants at doses of 200 and 400 mg/kg were investigated by acetic acid-induced writhings test, hot plate test and tail immersion test for mice.ResultsIt was found that all the three plants showed significant pain management effect (P<0.01) at a dose of 400 mg/kg, but showed a less significant effect at a dose of 20 mg/kg in the entire tests used for evaluation of analgesic activities (P<0.05).ConclusionsMethanol extracts of A. viridis, A. caudatus and A. spinosus show potent analgesic activities, and this study provides the scientific proof for their traditional claims.     

Symptomatic Hypocalcemia in Primary Hyperaldosteronism: A Case Report

The metabolic alterations caused by hyperaldosteronism are being increasingly recognized and have generated considerable interest among the medical fraternity. Hyperaldosteronism is suspected to have a pivotal role in the patho-physiology of congestive cardiac failure where it has been studied extensively. But its effects on calcium metabolism, parathyroid metabolism and renal handling of calcium are less well described. Recent experimental models have shed light into the roles played by previously unknown mechanisms in causing these metabolic alterations. We hereby report a case of primary hyperaldosteronism due to adrenal adenoma (Conn''s syndrome) who presented with a myriad of clinical features including symptomatic hypocalcemia, significant weight loss along with uncontrolled hypertension for a prolonged period before eventually detected to have primary hyperaldosteronism. Surgical removal of the causative tumor resulted in prompt disappearance of all the symptoms and signs and regain of lost weight.

Manual Small Incision Cataract Surgery: Experience at a Military Hospital

Background

Small incision cataract surgery came into practice with the advent of phacoemulsification. However, manual small incision cataract surgery (SICS) is a useful alternative for those who do not have access to phacoemulsification machine.

Method

A total of 69 cases of cataract were undertaken for manual incision cataract surgery and intra ocular lens (IOL) implantation using 6mm straight incision. The surgical technique and postoperative results are compared with the results of phacoemulsification and IOL implantation.

Result

Average postoperative astigmatism was ± 0.75 dioptres. Postoperative uncorrected visual acuity (UCVA) of 6/18 or better was observed in 51(71.9%) cases after first week of the surgery.

Conclusion

The study concludes that both phacoemulsification and small incision cataract surgery with intraocular lens (IOL) implantation are effective methods. However SICS with IOL implantation is a useful alternative in the absence of phacoemulsification machine.Key Words: Manual Small Incision Cataract Surgery (SICS), Extra Capsular Cataract Extraction (ECCE), Phacoemulsification, Intraocular lens implantation
