Orthoses and insoles are among the primary treatments and prevention methods of refractory plantar ulcers in patients with Hansen's disease. While dynamic plantar pressure and tactile sensory disturbance are the critical pathological factors, few studies have investigated whether a relationship exists between these two factors. In this study, dynamic pressure measured using F-scan system and tactile sensory threshold evaluated with monofilament testing were determined for 12 areas of 20 feet in patients with chronic Hansen's disease.

"Effectiveness of the sole protection and the plantar ulcer treatment of Micro Cellular Rubber (MCR) sandals" was investigated as a part of research enterprise "Research concerning the diagnosis, treatment, and the prevention of disability of an effective Leprosy in Myanmar" of the international medical treatment cooperation for three years since 2007. Furthermore "Introduction of Orthotics for the footdrop" was recently attempted through those activities. We participated for two research items from 2007, and reported on the research content and the result.

A 69-year-old woman presented with shivering and pain in the lower extremities on 5 April 2006; she was referred to the dermatology division of our hospital on the following day with difficulty in walking. She had been suffering from non-viral, non-alcoholic liver cirrhosis, and was being treated by the Division of Internal Medicine. Physical examination showed edema in the lower extremities and light purpuras on the groin and legs.

In a previous report (Luyo-Acero et al., 2004), we demonstrated that cytochrome b (Cyt b) gene analysis is an effective method for classifying several isolates of the genus Leishmania; hence, we have further applied this method to other Leishmania species in an effort to enhance the accuracy of the procedure and to construct a new phylogenic tree. In this study, a total of 30 Leishmania and Endotrypanum WHO reference strains, clinical isolates from our patients assigned to 28 strains (human and non-human pathogenic species) and two species of the genus Endotrypanum were analyzed.

A male newborn with skin erosions was born to a 32-year-old woman who was under treatment for pemphigus vulgaris that had been diagnosed 16 months earlier. Antibodies to desmoglein (Dsg)1 and Dsg3 were analyzed by enzyme-linked immunosorbent assay. Index values of antibodies to Dsg1 and Dsg3 were 49 (normal index values, <14) and 121 (normal index values, <7), respectively.

Linear immunoglobulin (Ig)A bullous dermatosis is a rare autoimmune subepidermal bullous dermatosis caused by circulating IgA autoantibodies directed against the antigens at the basement membrane zone. Most linear IgA bullous dermatosis cases are idiopathic, but some are associated with the use of certain drugs, infections, lymphoproliferative disorders, internal malignancies, autoimmune disorders, collagen diseases or, very rarely, other skin diseases, including autoimmune bullous diseases. Acquired hemophilia is also rare; it is a coagulation disease caused by anti-factor VIII IgG antibodies.

The exact species and/or strains of Leishmania parasites involved strongly influence the clinical and epidemiological features of leishmaniasis, and current knowledge of those influences and relationships is inadequate. We report that cytochrome b (cyt b) gene sequencing identified causal Leishmania parasites of 69 cutaneous leishmaniasis cases in Pakistan over a 3-year period. Of 21 cases in highland areas (Quetta city, Balochistan province), 16 (76.

Although ureteral obstruction is rarely noted in patients with gastric cancer at an advanced stage or at autopsy, the condition caused by authentic ureteral metastasis of gastric cancer is extremely rare. We experienced a case of gastric cancer in a 51-year-old woman who showed bilateral ureteral metastasis. The patient initially complained of right flank pain, caused by right ureteral obstruction, and was referred to our hospital, where she underwent a right nephroureterectomy, with suspicion of primary ureteral neoplasm.
