A case report on probable short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing following vairechanika nasya in Ménière's disease.

A 62 year old woman diagnosed with Ménière's disease, who underwent vairechanika nasya (VN) with shadbindu taila presented with short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) like phenomena immediately after the procedure. Rescue measures of abhyanga (local oil massage) and nadi sweda (local fomentation) were administered. Within half an hour the symptoms considerably declined and after 1 hour got completely relieved. The exact symptom disclosure by the patient who herself was a doctor helped in detecting the classic pattern of 'saw tooth phenomena' giving leads into a rare manifestation of probable SUNCT. Naranjo scale yielded zero score and thus the probable causality of VN with shadbindu taila could not be established so as to cause probable SUNCT as an adverse drug reaction (ADR). This case study is not put up for reporting an ADR of VN with shadbindu taila; rather this illustrates an uncommon, yet imperative adverse event of probable SUNCT while undergoing nasya procedure probably due to judgment error while fixing the VN dose in a patient with Ménière's disease. Transparent reporting of such unusual events during panchakarma procedures is necessary so that clinicians can understand, evaluate and take appropriate initiatives to manage them.

Prospective study to evaluate safety and efficacy of Zotarolimus Eluting Stent (PSEZES) in patients with long coronary artery lesions.

BACKGROUND: Although the safety and effectiveness of Drug-Eluting Stents (DES) has been established extensively, reports on long term clinical outcome with angiographic findings in patients with long coronary artery lesions are not many. METHODS: In this single-center prospective registry of 100 patients, a total of 110 denovo long lesions (>20 mm) were treated with Resolute Zotarolimus Eluting Stent (R-ZES). The patients were followed up clinically at 3, 6 and 12 months and follow up coronary angiography was performed at 9-months. The primary end point was one year rate of target lesion failure (TLF) which is a composite of cardiac death, target lesion myocardial infarction or ischemia driven target lesion revascularization (TLR). The secondary end points included definite or probable stent thrombosis, 9-month angiographic restenosis and late lumen loss. RESULTS: The mean age of patients was 58.7 ± 9.50 years with prevalence of diabetes as high as 60%. The mean lesion length was 24.67 ± 4.87 mm with a mean reference vessel diameter of 2.85 ± 0.32 mm and 67.3% were Type C lesions (ACC/AHA classification). Two patients died during follow-up, of which one was non-cardiac death. One patient had target vessel myocardial infarction and five patients (4.5%) had ischemia driven TLR. The incidence of TLF was 6.36%. Binary restenosis was seen in 7 out of 93 lesions (7.5%). Median late lumen loss at 9 month was 0.22 mm. No stent thrombosis was noted in the study. CONCLUSION: Implantation of R-ZES in real-world patients with long coronary artery lesions is safe with comparable efficacy to what is observed in the treatment of less complex lesions.

Molecular structure, vibrational spectra, HOMO, LUMO and NMR studies of 2,3,4,5,6-penta bromo toluene and bromo durene based on density functional calculations.

This work deals with the vibrational spectra of 2,3,4,5,6-Penta Bromo Toluene (PBT) and Bromo Durene (BD) by quantum chemical calculations. The solid phase FTIR and FT-Raman spectra of the title compounds were recorded in the regions 4000-400 cm(-1) and 4000-50 cm(-1), respectively. The spectra were interpreted with the aid of normal coordinate analysis based on density functional theory (DFT) using B3LYP/6-31G* level and basis set combinations and was scaled using various scale factors yielding a good agreement between observed and calculated frequencies. The infrared and Raman spectra were also predicted from the calculated intensities. Comparison of the simulated spectra with the experimental spectra provides important information about the ability of the computational method to describe the vibrational modes. The HOMO and LUMO energies were calculated within the molecule. (13)C and (1)H NMR chemical shifts results were also calculated and compared with the experimental values. Thermodynamical properties like entropy heat capacity, zero point energy have been calculated for the title molecules.

Vibrational assignment of the spectral data, molecular dipole moment, polarizability, first hyperpolarizability, HOMO-LUMO and thermodynamic properties of 5-nitoindan using DFT quantum chemical calculations.

The vibrational spectra of 5-nitroindan (NI) was computed using B3LYP methodology with 6-31G(*) and 6-31G(**) basis sets. The FTIR and FT-Raman spectra were recorded in the region 4000-400 cm(-1) and 4000-50 cm(-1) respectively. A similarity was achieved between the observed and calculated frequencies by refinement of the scale factors. The (1)H and (13)CNMR chemical shifts results were also compared with the experimental values. The Mulliken charges, the values of electric dipole moment (µ) of the molecule were computed using DFT calculations. The first order hyperpolarizability (ß0) and related properties (ß, α0, and Δα) of both are calculated using B3LYP method on the finite-field approach. The electronic properties HOMO and LUMO energies are calculated. Thermodynamic properties (heat capacity, entropy and enthalpy) of the title compound were calculated.

1-(2-Chloro-acet-yl)-3-methyl-2,6-diphenyl-piperidin-4-one.

The asymmetric unit of the title compound, C(20)H(20)ClNO(2), contains two crystallographically independent mol-ecules of similar geometry. The piperidine ring adopts a distorted boat conformation in both mol-ecules, in which the N atom assumes an almost planar configuration.

Vibrational spectroscopic studies of an organic non-linear optical crystal 8-hydroxyquinolinium picrate.

8-hydroxyquinolinium picrate (8-HQP) was synthesized by the addition of equimolar quantities of 8-hydroxyquinoline (8-HQ) and picric acid (PA). Single crystals were grown from N,N dimethyl formamide (DMF) by restricted evaporation method at room temperature. The solubility of 8-HQP was determined in different solvents at various temperatures. The structural characterization of the grown crystals was carried out by X-ray diffraction. Vibrational modes were classified on the basis of group theoretical analysis and the spectral bands were compared with those of parent compounds in order to propose a tentative assignment by recording FT-IR, FT-Raman and polarized Raman spectra in different crystal orientations. The crystal possess lower cut-off at 230 nm and good transparency as confirmed by optical transmittance studies.
