Prosthetic Rehabilitation of Orofacial Donor Site Fistula Following Surgical Reconstruction: A Clinical Report

Orofacial defects can be either congenital or acquired. Rehabilitation of these patients can be done using a surgical and/or a prosthetic approach. In situations where surgical reconstruction is not possible, prosthetic management becomes the only option. This clinical report describes a simple, economical, and effective technique for the prosthetic rehabilitation of a patient with oro-cutaneous fistula due to donor site dehiscence following tumor defect reconstruction.     

Zoonotic sporotrichosis of lymphocutaneous type in a man acquired from a domesticated feline source: report of a first case in southern Karnataka, India

Background  Sporotrichosis is commonly encountered due to traumatic implantation of thorns or decayed vegetation with the dimorphic fungi, Sporothrix schenckii . Zoonotic spread of Sporotrichosis is rare and we describe here the first case of feline transmission of lymphocutaneous sporotrichiosis encountered in India.
Methods  An excision biopsy of nodulo-ulcerative lesion from the patients right elbow and forearm were collected for histopathology and portion of the specimen processed for mycological work up. Animal pathogenicity test performed in Swiss albino mice with intraperitoneal & foot pad inoculation. In addition an investigation of the ulcerative skin lesion from the domesticated cat was carried out.
Results  Histopathology examination of tissue sample from the patient and feline lesion revealed granulomatous reaction and a few slender elongated yeast cells consistent with Sporotrichosis. The diagnosis was confirmed by culturing Sporothrix schenkii and demonstration of thermal dimorphism. Pathogenicity testing in mice lead to orchitis in 12–15 days and the organism was re-isolated in pure culture. The patient was treated with oral saturated potassium iodide solution with complete resolution of the lesions.
Conclusion  Close contact with infected domesticated feline can be a potential source of transmission for Sporotrichosis as evidenced in this report.     

Treatment of Old World cutaneous leishmaniasis with dapsone, itraconazole, cryotherapy, and imiquimod, alone and in combination

Background  Cutaneous leishmaniasis (CL) is a major public health problem. The currently available therapies are expensive, not freely available, toxic, and not always curative. A simple, effective, noninvasive therapeutic approach is required for the treatment of CL.
Aims  To determine the clinical patterns of CL and to report our experience in the management of CL.
Methods  One hundred and ten patients with CL seen between January 2005 and December 2007 were included in this study. The diagnosis was based on clinical features, parasitologic diagnosis, histopathology, and culture. Each patient was treated according to disease severity with either topical (cryotherapy or imiquimod) or systemic (itraconazole or dapsone) monotherapy, or a combination of these modalities.
Results  CL was more common in adult expatriate men, with the upper limbs as the most commonly affected site. Noduloulcerative CL was the most common presentation (84.6%). Atypical CL was found in 18 patients. Skin biopsy was the most common diagnostic technique (66.6%). Monotherapy showed an overall success rate of 56.41%, whereas combination therapy was successful in 69.56% of cases. Cryotherapy alone was successful in 68.18% of cases. Imiquimod alone was ineffective.
Conclusion  A stepwise approach represents a rational and practical way of confirming CL. A combination of itraconazole/dapsone and topically applied imiquimod is safe, simple, and effective for the treatment of CL. More studies are needed to establish the role of such an approach. Cryotherapy is also safe, simple and effective for the treatment of CL.     

Ultrasound of Adnexal Masses

Current advancements in imaging technology, especially three-dimensional/four-dimensional ultrasound and contrast-enhanced imaging, have increased the diagnostic yield of adnexal masses. The benefit of ultrasound is the characterization of an adnexal mass, suggesting the probable etiology of the mass. Masses may be divided as solid, cystic, or complex. It is predominantly the solid and complex masses that need a thorough evaluation. The role of color-flow imaging is now gaining importance and criteria for distinguishing between benign and malignant masses are often possible. Availability of a scoring system enables the differentiation of small adnexal masses. Several benign lesions may present as complex masses but can be distinguished and diagnosed on sonography. The availability of 3D ultrasound has been of great use to understand spatial relations and vascular morphology. Sonography allows a more detailed assessment of morphologic features of an adnexal mass. With a benign-appearing adnexal mass on sonography, the need for any further diagnostic tests is often obviated.
