We present a case of maxillary sinusitis caused by Schizophyllum commune, in a 50-year-old female. The patient presented with nasal obstruction, purulent nasal discharge from right side of the nose, cough, headache, and sneezing. Computed tomography revealed extensive opacity of the right maxillary sinus as well as erosion of the nasal wall and maxillary bone. Functional endoscopic sinus surger...

BACKGROUND/AIM Vaginal and cervical swab culture is still very common procedure in our country's everyday practice whereas simple and rapid diagnostic methods have been very rarely used. The aim of this study was to show that the employment of simple and rapid diagnostic tools [vaginal fluid wet mount microscopy (VFWMM), vaginal pH and potassium hydroxide (KOH) test] offers better assessment of...

AIMS To determine the sensitivity, specificity and predictive values of potassium hydroxide (KOH) wet mount, Gram stain, Giemsa stain and Kinyoun's acid-fast stain in the diagnosis of infective keratitis. METHODS A retrospective analysis of all patients with clinically diagnosed infective keratitis presenting between September 1999 and September 2002 was carried out. Corneal scrapes were take...

In order to evaluate the effect of potassium silicate spray on the control of coffee leaf rust and coffee yield, an experiment was conducted during the 2005/2006 and 2006/2007 growing seasons on Coffea arabica cv. Catuaí Vermelho IAC 144, in a location situated at an elevation of 850 m in Coimbra, Minas Gerais, Brazil. The treatments consisted of: 1 potassium silicate; 2 potassium silicate + co...

The use of tetramethylammonium hydroxide (T.M.A.H.) in place of potassium hydroxide in the Zimmermann reaction has been investigated. Although various pure steroids have different colour equivalents, a comparison of the results of 17-ketosteroid and 17-hydroxycorticosteroid estimations on a series of urines showed that the differences for the two reagents were only small and may be ignored. Tet...

To realize the nanofabrication of silicon surfaces using atomic force microscopy (AFM), we investigated the etching of mechanically processed oxide masks using potassium hydroxide (KOH) solution. The dependence of the KOH solution etching rate on the load and scanning density of the mechanical pre-processing was evaluated. Particular load ranges were found to increase the etching rate, and the ...

BACKGROUND Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible lesions. Potassium hydroxide is a strong...

Introduction: The clinical pictures of nail dystrophies caused by different fungi are seldom diagnostic. Mycological confirmation with appropriate diagnostic techniques including direct microscopy and fungal culture is important to ensure correct diagnosis and treatment. Microscopy can be performed using potassium hydroxide (KOH) mount and histological evaluation of nail plate specimens with th...

Ultrasonic-assisted alkaline (UAA) technology is applied to extract cellulose from lignocellulose biomass, sugarcane bagasse (SCB). The SCB a type of agriculture residue that consists about 50 %(w/w) content, thus potential serve as feedstock for production via UAA technology. Due the complex and sturdy structure lignocellulosic most current extraction processes in industry still apply multi-st...

Efficient and reasonable utilization of waste biomass resources can not only avoid serious material resources, but also solve the problem environmental pollution. Therefore, development efficient environmentally friendly carbonization technology has important practical significance. Here, activated carbon from orange peel (OAC) is prepared by potassium hydroxide (KOH) activation combined with h...
