This study analyzed data from treatments of 385 cases of generalized pustular psoriasis (GPP) from 325 hospitals in Japan. Retinoid treatment was effective in 84.1% of patients, methotrexate in 76.2%, cyclosporine in 71.2%, oral PUVA therapy in 45.7%, and tonsillectomy in 16.7%. Short-term therapy with systemic corticosteroid for GPP during only the phase with severe systemic clinical findings may be also effective (75.4%). However, these treatments for GPP each differed in clinical effects, prognosis, and side effects. These findings may be useful in creating guidelines for treatment of generalized pustular psoriasis. Further studies based on these specific clinical effects are necessary.

Internet use by physicians and patients has become very popular in Japan. Fifty percent of physicians use the Internet to search for medical and other information. Over the past year, 22% of patients used the Internet to obtain medical information. Because there are no restrictions within Japan on using Web sites to advertise medical treatment, information can be freely sent out, and over the past two or three years this practice has increased dramatically. Internet medical information provides information about illnesses and medications, and it helps improve the quality of life of patients and families.Yet, depending on the content of the information provided and the way this information is used, there is a potential negative side as well. On principle, users are responsible for the way information is used, but there is a need for information providers to consider users' safety and to make the information effective for use. Because there is no absolute standard for evaluating the value of medical information, it is necessary to establish a system that opens a dialogue with society and that continuously accumulates high-quality information through the collection of various evaluations, rather than rely on an established authority. For industries and organizations related to commercial pursuits, in particular, it is most effective to establish their own codes for ethical conduct, rather than rely on governmental regulations. At the same time, it is important to have a confirmation function to evaluate how goals set by the outside are being implemented.Aiming at establishing a framework for the Internet medical usage, the Japan Internet Medical Association (JIMA) was founded in 1998 by medical professionals, lawyers, researchers, consumer representatives, patients and their families. We propose a system that would combine feedback from users, who would take on the role of evaluators of the implementation of an ethical code, with a displayed mark that verifies the identity of the Web site. Objective evaluation of information is needed to ensure that users have the power to make choices. Medical experts or patient and family groups would assist in this task. The development of medical care will be promoted through patients and physicians' working together in the accumulation of shared resources for good medical care information.

PurposeIn stage II colon cancer, patients with many retrieved lymph nodes (LNs) have been reported to have better oncological outcomes. We tested the hypothesis that the greater number of retrieved LNs is related to a larger LN size.MethodsThe subjects comprised 320 patients with stage II colon cancer who underwent curative resection. All operations were elective and were performed by the same surgeons. The maximum long axis and short axis diameters of LNs were measured on hematoxylin-eosin-stained specimens.ResultsA total of 4,744 LNs were evaluated. The number of retrieved LNs was 14.8 ± 10.1 (mean ± SD). The long axis diameter was 4.8 ± 2.6 mm, with a median value of 4.3 mm, a maximum value of 20.4 mm, and a minimum value of 0.6 mm. The corresponding short axis diameters were 3.4 ± 1.7, 3.0, 15.1, and 0.5 mm, respectively. The highest correlation coefficient for the association with the number of LNs was obtained for the maximum value of the long axis diameter (0.59). Multivariate analysis revealed that age, tumor location, pathological T stage, and the maximum long axis diameter were independent prognostic factors. The number of LNs was not a significant factor. Patients with less than 12 LNs and a maximum long axis diameter of less than 10 mm had significantly poorer outcomes (p < 0.001).ConclusionIn patients with stage II colon cancer, the maximum long axis diameter of LNs correlated with the number of LNs and was an independent prognostic factor.

Telemedicine is the provision of professional medical services from sites removed from the patient. This study was conducted in order to assess the reliability of psychiatric evaluations via video-consultation. The inter-rater reliability was determined for each interviewing condition by employing the reliability-testing paradigm in which the brief psychiatric rating scale (BPRS) and the interclass correlation coefficient (ICC) are used. The inter-rater reliability scores between face-to-face interviews and interviews conducted by video at two different levels of image qualities were compared by the authors. Reliability was found to be in perfect agreement in each of the interviewing conditions. This study verifies that telepsychiatry is a reliable method of assessing patient conditions. It may be used to provide much needed mental health-care services to patients whose access to them is restricted.
