Differential Chemical Compositions of the Essential Oils of the Shoot Organs, Rhizomes and Rhizoids in the Turmeric Curcuma longa Grown in Indo-Gangetic Plains

The turmeric Curcuma longa cv Roma plants grown at 26,000 plants per hectare were harvested at the age of 16 months and separated into leaf laminas, petioles, stem, inflorescence, primary and secondary rhizomes and rhizoids. These organs were hydrodistilled separately to obtain essential oils which were characterized by GC and GC-MS analyses; 15 terpenoids could be identified. On average basis, a plant of C. longa cv Roma yielded about 7.72 g oil; about 2 g from leaves, 2 g from rhizoids and 3.5 g from rhizomes. About 26,000 plants could be accomodated in a hectare of land. The stem, rhizome and rhizoid essential oils were similar in composition. The rhizome essential oils were highly rich in a- and ß-turmerones (40.8 %), myrcene (12.6 %), 1,8-cineole (7.7 %) and p -cymene (3.8 %). The leaf petiole and lamina essential oils were rich in myrcene (35.9 %), 1,8-cineole (12.1 %) and p -cymene (21.7 %). This oil contained turmerones but in lower concentrations.

Naso-cutaneous fistula following transcanalicular laser dacrocystorhinostomy.

We report a case of naso-cutaneous fistula due to thermal injury during transcanalicular laser dacryocystorhinostomy followed by superadded infection with coagulase negative staphylococcus in a diabetic patient. The case highlights the importance of meticulous wound care in the management and possibility of its occurrence even with minor thermal injury in immunocompromised patients.

Transcanalicular Laser-Assisted Dacryocystorhinostomy With Endonasal Augmentation in Primary Nasolacrimal Duct Obstruction: Our Experience.

PURPOSE To evaluate and compare the success rate of transcanalicular laser-assisted dacryocystorhinostomy with endonasal augmentation, with and without intubation, in patients suffering from primary acquired nasolacrimal duct obstruction, at 1 year of follow up. METHODS A prospective, randomized interventional pilot study was conducted at a tertiary care center, in accordance with the guidelines of Declaration of Helsinki. Sixty eyes of 60 adult patients with primary acquired nasolacrimal duct obstruction were included. The participants were divided randomly into 2 equal groups (A and B-without and with bicanalicular intubation, respectively). An osteotomy was first created using 980 nm diode laser (set at 8W continuous mode) transcanalicularly and then enlarged intranasally using Blakesleys nasal forceps, followed by bicanalicular silicon intubation in group B patients. The tubes were removed at the end of 8 weeks. The ostium size was assessed endoscopically at 8 weeks and again at the end of follow up, at 1 year. A successful outcome was defined in terms of ostium patency at the end of 1 year. The results were analyzed at the end of a follow up of 1 year, using various statistical tests (p < 0.05). RESULTS The mean age of the patients was 35.3 ± 15.89 years, with 23 male and 37 female patients, the 2 groups having a similar male:female ratio. An overall success rate of 90% was achieved at the end of 1 year with no statistically significant difference between the groups. Postoperative complications like tube displacement and punctal, canalicular injury were more in the intubated group. The average osteotomy size was 8.06 ± 5.4 mm at the end of 1 year. CONCLUSIONS Transcanalicular laser-assisted dacryocysto rhinostomy, with endonasal augmentation, is a scarless, effective, daycare procedure, for treatment of primary acquired nasolacrimal duct obstruction with no additional advantage offered by silicone intubation.
