This constitutes an economic burden on the resources of states and hence has prompted many international organizations to devise awareness and educational programs about the dangers of this the disease and ways to deal with it. There are serious complications to diabetes which may include; high blood pressure, heart and kidney diseases, eye problems, neuropathy, and diabetic foot. The most feared development of this disease is the diabetic foot as it may lead to amputation. This study examines the prevalence of diabetes and complementary alternative medicine in the treatment of this disease and the attitudes toward managing diabetic foot in Makkah and Taif area in Saudi Arabia. Methods: Questionnaires were distributed in the Western region of Saudi Arabia.The sample size was 750. Responses were collected and proper descriptive statistical analysis was applied. Results: A...

As urethral plate preservation got an important role, transverse preputial island flap (TPIF) urethroplasty is one of the preferred technique for sub-coronal and distal penile hypospadius. Methods: This study was conducted at urology department, DMCH, from February, 2014 to June, 2017 where 15 patients underwent TPIF urethroplasty. Inner preputial flap with its pedicle was developed and separated from the dorsal penile skin which was sutured to the urethral plate in an onlay manner over a stent by running suture. Glanuloplasty and meatoplasty was done and skin closed.SPC was done in every cases. Dressing was checked on 5th POD, stent was removed after 03 weeks. SPC was removed 2 to 3 days after satisfactory voiding. All patients were followed up at 6th and 12th week. Results: Among the 15 patients age range was 2-14 years and mean age. Sub-coronal in 4 and distal penile was in 11 patients. Fo...

The empirical role of medium-chain triglyceride (MCT) or long-chain triglyceride (LCT) on the emulsification mechanistics of SMEDDS was studied. The effect of type of vehicle on the fate of drug after dispersion was also investigated. Methods: Miscibility profiles and self-micro-emulsifying regions for various lipid systems were screened by varying types of oil, cosurfactant and surfactant. Solubility of Curcumin was measured in various optimized vehicles.Dynamic equilibrium phase studies were performed and phase boundaries were determined for the lipidwater systems. Results: An archetypical Type IIIA micro-emulsion system comprising 21%w/w Crodamol GTCC, 49%w/w Glycerox 767HC and 30% w/w Etocas 35 HV was developed which can potentially mimic the bioavailability of Curcumin. MCT or LCT included in SMEDDS appears to influence emulsification process by ...

Patients and Methods: This observational study intended to compare the outcome between PCNL without JJ stent and PCNL with JJ stent of 50 cases of renal stone disease according to the inclusion and exclusion criteria and randomly assigned to Group - A (PCNL without JJ stent) and Group - B (PCNL with JJ stent). This study was conducted in the department of urology, Dhaka Medical College Hospital from July 2014 to June 2016. During postoperative period, both groups were compared with respect to fever, loin pain, dysuria, frequency of micturation, duration of haematuria, continuation of urine leakage, hospital stay, urinoma and hematoma and urinary tract infection. Results: Among the 50 patients, the mean postoperative hospital stay was significantly longer in PCNL with JJ stent (4.48 ± 2.14 days) than that of PCNL without JJ stent (2.60 ± 0.50 days). The ...

Nonetheless, lipid-based formulations require that oil content is encapsulated in soft gelatin capsules which might exhibit some disadvantages. To overcome these limitations, solid self-micro-emulsifying drug delivery system (S-SMEDDS) is introduced as an alternative approach. The preferred dosage form for BCS class I compounds is tablets yet, some drugs which belong to this category might suffer from enzymatic degradation and gut wall efflux. The effect of converting liquid SMEDDS into compressed tablets containing a BCS class 1 compound is investigated. A SMEDDS oil formulation representing type III A lipid class was converted into S-SMEDDS using solid carrier adsorption method and compressed into tablets containing theophylline. The effect of oil loading factor on compressibility, disintegration and dissolution kinetics of theophylline from various tablet formulation was investigated. Increasing oil content in the compressed tablets ensued in a progressive decrease in the hardness of tablets. Analysis of the dissolution kinetic data for tested theophylline preparations shows that it follows first-order or Higuchi kinetics. Fast dissolving tablet formulations were obtained at including an optimum oil concentration of 5% w/w.

Yet, these systems have the capacity to solubilize aqueous-based materials within its lipid matrix as L2 phase (W/O microemulsion). This characteristic is utilized in this investigation to incorporate aqueous flavors within oil vehicle as an approach to mask bitter taste of drugs. Miscibility profiles and self-micro-emulsifying regions for various lipid composites were screened by constructing ternary phase diagrams using different types of oil, cosurfactant and surfactant. Solubility of bitter taste model drug was measured in various optimized vehicles. Dynamic equilibrium phase studies were performed and phase boundaries were determined for the lipid-aqueous flavors-water systems. Self-micro-emulsifying system comprising Crodamol GTCC/ Glycerox 767HC /Croduret 40 ss at ratios of {0/80/20}, {6/54/40} or {10/40/50} have shown capacity to solubilize, aqueous-based materials including; strawberry flavor, sucrose and citric acid as L2 phase. Phase behavior study has revealed that clear dispersions can be obtained at all dilutions with water. Potential flavored self-microemulsifying lipid formulations representing type III lipid class system were developed. Aqueous flavors loaded into these vehicles can be used to mask bitter tastes in oral pharmaceuticals.

Hydrolysis of salts 11 affords 3H-4,5-dihydropyrazoles 12. 1-Aza-2-azoniaallene salts 1 react with cyclic azoalkanes 12 to produce the N-(azoalkyl)diazenium salts 14 or the formazanium salts 15 depending on the substituents of the starting materials. The structure of 15c is secured by X-ray structural analysis.

With diisopropylcarbodiimide the triazolium salt 13 and with norbornene a tricyclic pyrazolium salt 14 are obtained. Concurrent to these cycloadditions the by-product 12 is formed by intramolecular cyclization of the cumulene 8. Similarly, the intramolecular cyclization product 18 is isolated as the sole product when the I-aza-2azoniaallene salt 17a (prepared from the ethyl carbazone of camphor by chlorination and treatment of the product 16a with SbCl,) was treated with nitriles, carbodiimides or alkenes. In contrast, 1,2,btriazolium salts 20a-c, 23c, respectively pyrazolium salts 20d-f, and 1,3,4-thiadiazolium salts 23a,b are obtained by reaction of the 1-aza-2-azoniaallene salt 17b with nitriles, respectively alkenes, alkynes, diisopropylcarbodiimide, and isothiocyanates. The constitutions of two of these products (20e, 23a) were secured by X-ray structural analysis.
