Nationwide survey on complementary and alternative medicine in cancer patients in Japan.

PURPOSE: To determine the prevalence of use of complementary and alternative medicine (CAM) by patients with cancer in Japan, and to compare the characteristics of CAM users and CAM nonusers. PATIENTS AND METHODS: A questionnaire on cancer CAM and the Hospital Anxiety and Depression Scale were delivered to 6,607 patients who were treated in 16 cancer centers and 40 palliative care units. RESULTS: There were 3,461 available replies for a response rate of 52.4%. The prevalence of CAM use was 44.6% (1,382 of 3,100) in cancer patients and 25.5% (92 of 361) in noncancer patients with benign tumors. Multiple logistic regression analysis determined that history of chemotherapy, institute (palliative care units), higher education, an altered outlook on life after cancer diagnosis, primary cancer site, and younger age were strongly associated with CAM use in cancer patients. Most of the CAM users with cancer (96.2%) used products such as mushrooms, herbs, and shark cartilage. The motivation for most CAM use was recommendation from family members or friends (77.7%) rather than personal choice (23.3%). Positive effects were experienced by 24.3% of CAM users with cancer, although all of them received conventional cancer therapy concurrently. Adverse reactions were reported by 5.3% of cancer patients. CAM products were used without sufficient information by 57.3% of users with cancer and without a consultation with a doctor by 60.7% of users. CONCLUSION: This survey revealed a high prevalence of CAM use among cancer patients, without sufficient information or consultation with their physicians. Oncologists should not ignore the CAM products used by their patients because of a lack of proven efficacy and safety.     

Gastric adenosquamous carcinoma producing granulocyte-colony stimulating factor

We report a case of adenosquamous carcinoma of the stomach that produced granulocyte-colony stimulating factor (G-CSF). The patient, who had an admission diagnosis of advanced gastric cancer, had marked leukocytosis without evidence of infection. After leukemia and metastatic leukemoid reaction were excluded by bone marrow examination, a G-CSF-producing cancer was suspected as the cause of the abnormally elevated serum G-CSF level. The resected stomach tumor was histologically diagnosed as adenosquamous carcinoma; positive expression of G-CSF by tumor cells was shown with immunohistochemical detection, which confirmed the preoperative diagnosis. Recurrent disease in the liver and lymph nodes, accompanied by leukocytosis and re-elevation of serum G-CSF, developed just 3 months after the curative gastrectomy and adjuvant chemotherapy. All of the recurrent disease was resected, restoring normal levels of serum G-CSF. The patient survived for almost 2 years after the initial surgery with extensive chemotherapy, including weekly treatment with paclitaxel, before finally succumbing to liver failure secondary to extensive liver metastasis.     

A comparison of patient-reported outcomes and arthroscopic findings between drilling and autologous osteochondral grafting for the treatment of articular cartilage defects combined with anterior cruciate ligament injury

BackgroundTo compare the patient-reported outcomes and arthroscopic findings between drilling and autologous osteochondral grafting (AOG) for the treatment of articular cartilage defects combined with anterior cruciate ligament (ACL) injuries.MethodsThe subjects were 40 patients who had articular cartilage defects in the weight-bearing part of the medial and lateral femur condyle combined with ACL injuries that were treated by drilling (20 patients) or AOG (20 patients) at the same time as ACL reconstruction was performed. In the drilling group patients, lesions were penetrated with multiple 1.2-mm Kirschner wires, and in the AOG group patients, grafts were made to cartilage defects from one to three osteochondral pegs harvested from the less-weight-bearing periphery of the articular surface of the femoral condyle. The patient-reported outcomes were assessed using the International Knee Documentation Committee (IKDC) subjective knee examination score. Second-look arthroscopy was performed to evaluate the repaired cartilage macroscopically.ResultsThe median follow-up duration was 25 (range, 12–42) months. The IKDC scores were significantly improved from 64.4 to 95.4 points in the drilling group and from 52.3 to 94.3 points in the AOG group, with no difference between the two groups, although there was a difference in the repaired cartilage findings of arthroscopy.ConclusionIn this study, no differences in IKDC scores were found in patients with a concomitant ACL rupture and an osteochondral lesion treated by drilling or AOG at a minimum follow-up of 1 year, regardless of the differences at arthroscopic grading of the ICRS classification.Level of evidenceCase–control study (LEVEL III).     

Cutaneous necrotizing vasculitis as a manifestation of familial Mediterranean fever

Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disease, which is characterized by recurrent and paroxysmal fever, peritonitis, arthritis, myalgia, and skin rashes. Although various skin lesions such as “erysipelas‐like erythema”, urticaria, nonspecific purpura, and subcutaneous nodules have been described, cutaneous vasculitis is rare. We report a Japanese case of sporadic FMF accompanied by cutaneous arteritis at the time of febrile attacks of FMF. Gene analysis revealed M694I mutation in a single allele of the MEFV gene, and oral colchicine successfully controlled both periodic fever and subcutaneous nodules of arteritis. Cutaneous necrotizing vasculitis repeatedly emerging with febrile attacks should be included among the skin manifestations of FMF.     

Eleven novel microsatellite loci for Japanese whiting (Sillago japonica) and cross amplification in the endangered small-scale sillago (Sillago parvisquamis)

Japanese whiting (Sillago japonica) are a relatively common species that inhabit coastal shallow waters in Japan and are the target species in an important recreational fishery. We isolated eleven candidate microsatellite loci from a small insert genomic DNA library of S. japonica. We screened for polymorphisms in the eleven loci using wild individuals (n = 48) collected from Suounada Sound, in the Seto Inland Sea, Japan. The number of alleles per locus ranged from 6 to 26 with no evidence of linkage disequilibrium. Observed heterozygosity ranged from 0.58 to 0.98 with one locus exhibiting a significant departure from Hardy–Weinberg equilibrium. A test for cross-amplification using the closely related species, Sillago parvisquamis yielded scoreable peaks and a high level of polymorphism in four loci. These polymorphic microsatellites can be used to identify population structure in S. japonica and provide potential markers for the endangered S. parvisquamis.     

Histology-Based Assessment of Sonazoid-Enhanced Ultrasonography for the Diagnosis of Liver Metastasis

This retrospective study aimed to assess the diagnostic performance of contrast-enhanced ultrasound with Sonazoid (S-CEUS) for liver metastasis. We enrolled in this study 98 patients with 148 histologically proven liver lesions, with 121 metastases and 27 non-metastases. The S-CEUS technique showed sensitivity in 95.0% (115 of 121), specificity in 44.4% (12 of 27) and accuracy in 85.8% (127 of 148) for the diagnosis of metastasis. Higher body mass index had a negative influence on the positive predictive value and accuracy, and a greater depth of the lesion had a negative influence on the accuracy. The management was changed in 8 patients (8.2%) because of S-CEUS findings. In conclusion, the addition of S-CEUS may offer a great benefit by improvement of the quality of diagnosis and management for patients with cancer who have a tentative diagnosis of liver metastasis by contrast-enhanced computed tomography.
