Increased touch-evoked itch (punctate hyperknesis) in postherpetic itch: Implications of reduced intraepidermal nerve fibers representing small fiber neuropathy.

Chronic itch conditions are often accompanied by neural itch sensitization, known as hyperknesis (excessive itch induced by stimuli that would normally induce only mild itching or pain) and alloknesis (considerable itch evoked by light tactile stimuli). Herpes zoster (shingles) can cause neuropathic itch (postherpetic itch), although it is unknown whether hyperknesis accompanies postherpetic itch. The authors report five patients with postherpetic itch who showed increased touch-evoked itch (punctate hyperknesis) in the affected skin areas compared with the contralateral site.

A cone-beam computed tomographic assessment of the proximity of the maxillary canine and posterior teeth to the maxillary sinus floor: Lessons from 4778 roots.

Introduction: When tooth roots protrude into the maxillary sinus, apical root resorption and tipping may occur during horizontal tooth movement across the sinus floor. Three-dimensional cone-beam computed tomography (CBCT) images may provide detailed information without distortion and overlap. We evaluated the relationships between the maxillary tooth root apices and the maxillary sinus floor using CBCT.

Prognostic value of tumor-infiltrating dendritic cells expressing CD83 in human breast carcinomas.

DCs are the most potent antigen-presenting cells that play a major role in initiating the antitumor immune response. Although the clinical significance of TIDCs has been investigated in a variety of human cancers, few studies have focused on the in situ maturation status of DCs. We have analyzed the maturation-specific significance of TIDCs in the prognosis of patients with breast carcinoma.

Clinical study to identify specific characteristics of cancer newly developed in the remnant stomach.

Background: Cancer newly developed in the remnant stomach (CRS) after partial gastrectomy is worthy of attention not only because it is a typical model of carcinogenesis but also from the aspect of cancer diagnosis.

Methods: We treated 47 patients with CRS in the 20 years from 1979 to 1998. Clinicopathological variables, as well as long-term survival results after the second surgery, were reviewed to clarify whether there were any differences in the characteristics of this disease entity compared with the usual primary gastric cancer.

PSK, a protein-bound polysaccharide, overcomes defective maturation of dendritic cells exposed to tumor-derived factors in vitro.

Dendritic cells (DC) are the most potent antigen-presenting cells that induce specific anti-tumor immunity. To obtain potent efficacy of immunotherapy using infusion of activated DC, it is necessary to overcome defective function of DC in tumor-bearing patients. We examined whether the treatment with PSK, a biological response modifier derived from Basidiomycetes, could allow DC to avoid inhibition of functional maturation by tumor-derived factors in vitro.

[A case of stage IV gastric cancer with multiple liver metastases and carcinomatous ascites responding to TS-1 for six months before progression].

We report the case of a 72-year-old male with Stage IV gastric cancer accompanied by multiple liver metastases and carcinomatous ascites which responded to chemotherapy using TS-1. Treatment of the patient with daily oral administration of 120 mg TS-1 for 4 weeks resulted in complete regression of the liver metastases and ascites, as well as a 35% reduction in the size of the primary lesion. After 2 cycles, the primary tumor size was reduced to 55% and serum CA19-9 and CA125 levels were decreased to the normal ranges.

Sclerotherapy with a ligation of incompetent veins for a stasis ulcer due to varix cruris: minimal invasive therapy for varix cruris.

A retrospective analysis was performed on 11 patients (mean age 50 years), consisting of 8 men and 3 women, with a stasis ulcer due to varix cruris who underwent sclerotherapy with a ligation of incompetent veins on an outpatient basis. The follow-up ranged from 26 to 76 months (mean 53 months). The ulcers healed in 14 to 128 days (mean 41 days) after this procedure except in 1 patient.
