A case of Sjögren’s syndrome presenting as hypokalemic myopathy due to distal renal tubular acidosis
Kiooshi Migita Hironaga Kuwahara Yasuko Hirai Tan Tominaga Naokata Yokoyama Masahiro Tominaga Hideki Nakamura Yojiro Kawabe Tomoki Origuchi Takashi Taguchi Katsumi Eguchi 《Modern rheumatology / the Japan Rheumatism Association》1999,9(1):113-118
We report a case of hypokalemic myopathy with distal renal tubular acidosis which leads to the diagnosis of Sjögren’s syndrome (SS). A 67-year-old man was admitted to our department for progressive muscle weakness and myalgia. Laboratory data demonstrated hypokalemia with hyperchloremic acidosis, elevated muscle enzyme and inability to acidify urine. Findings of interstitial nephritis, which is consistent with renal tubular acidosis in SS, were found on renal biopsy. Remarkable changes of the renal tubule, including tubular atrophy, dilatation and intratubular casts, were observed. Potassium replacement therapy normalized the marked elevated urinaryβ 2-microglobulin excretion as well as the improvement of muscle symptoms. Taken together with our findings, it it suggested that sustained hypokalemia may partly contribute to the exacerbation of the pre-existing renal tubular disorder in SS. 相似文献

A 55-year-old woman with bilateral vertebral artery (VA) aneurysms was transferred to our hospital. She suffered from a minor stroke. Magnetic resonance imaging (MRI) for the stroke incidentally revealed bilateral VA aneurysms. Due to its size, more observation was recommended, and the patient was found eager to be treated. Both side surgeries were found inappropriate because of severe lower cranial nerve disturbances. The right aneurysm involved the posterior inferior cerebellar artery (PICA) and the V4 segment was deviated to the right side. Therefore, the smaller right aneurysm was treated first with an occipital artery (OA)-PICA bypass and a V3-radial artery graft (RAG)-V4 bypass followed by proximal clipping of the PICA and the right VA. The right VA was successfully remade by RAG and the right aneurysm was not revealed on postoperative examination. By doing so, the opposite aneurysm was able to be eliminated by the parent artery occlusion even by using an interventional radiology (IVR). The V3-RAG-V4 bypass is a useful method for treating bilateral VA aneurysms. This is a new bypass which has not been reported so far to the best of our knowledge. 相似文献

Background
FOLFOXIRI is now regarded as the chemotherapy regimen that offers the best platform for the treatment of colorectal cancer. However, the safety and efficacy of FOLFOXIRI + panitumumab has not been demonstrated. We conducted a phase I study to determine the recommended dose of FOLFOXIRI + panitumumab as first-line treatment for RAS wild-type metastatic colorectal cancer (mCRC).Methods
Patients received combination therapy consisting of panitumumab (6 mg/kg on day 1) + FOLFOXIRI [irinotecan (CPT-11), oxaliplatin (L-OHP) 85 mg/m2, and folinate (LV) 200 mg/m2] on day 1, followed by fluorouracil (5-FU) 3200 mg/m2 infused as a 46-h continuous infusion starting on day 1) repeated every 2 weeks as first-line treatment of RAS wild-type mCRC patients. A decrease in CPT-11 dose was planned (started at level 1: CPT-11 165 mg/m2).Results
Seven patients were enrolled, and six were assessed for safety and efficacy. Maximum tolerated dose was not reached at level 1; all patients were treated at these levels. The common Grade 3 or 4 relevant toxicities were diarrhea (50%), hypokalemia (33%) and stomatitis (33%). No treatment-related deaths occurred. Of the six patients assessed four had partial response and the two others had stable disease; hence, the response rate was 66.7% (95% confidence interval 28.9–100%) and the disease control rate was 100%. Time to protocol treatment failure was 7.2 (1.4–7.3) months.Conclusion
The FOLFOXIRI + panitumumab chemotherapy regimen was well tolerated by our patients with mCRC and showed promising anti-tumor activity. The recommended phase II dose was determined to be the same as the standard doses of this regimen used worldwide.45.

A case of leiomyosarcoma arising in the lesser sac in a 64-year-old man is presented. A second operation was required because
of local recurrence 6 years following the first operation. A review of the literature revealed that only eight cases of leiomyosarcoma
arising in the lesser sac, including our case, were reported. Almost all of these patients had symptoms of abdominal pain
or distension. The tumor tended to grow to a large size and about 90 percent were over 10 cm in the maximal diameter. The
prognosis of these series was poor and our own patient seems to be the second 5 year survivor.

Gene doping is prohibited for fair competition in human and horse sports. One style of gene doping is the administration of an exogeneous gene, called a transgene, to postnatal humans and horses. Although many transgene detection methods based on quantitative polymerase chain reaction (PCR), including real-time PCR and digital PCR, have been recently developed, it remains difficult to reliably detect low-copy transgenes. In this study, we developed and validated a nested digital PCR method to specifically detect low-copy transgenes. The nested digital PCR consists of (1) preamplification using conventional PCR and (2) droplet digital PCR detection using a hydrolysis probe. Using 5, 10, 20, 60 and 120 transgene copies as template, 496.0, 1089.7, 1820.7, 4313.3 and 7840.0 copies per microlitre, respectively, were detected using our nested digital PCR. Although high concentrations of phenol, proteinase K, ethanol, EDTA, heparin and genomic DNA all inhibited preamplification, their effects on the digital PCR detection were limited. Once preamplification was successful, even substitution of bases within the primers and probes had minimal effects on transgene detection. The nested digital PCR developed in this study successfully detected low-copy transgenes and can be used to perform a qualitative test, indicating its usefulness in the prevention of false positives and false negatives in gene-doping detection. 相似文献

Although stent implantation into aortic coarctation has been performed solely under fluoroscopy, we successfully applied intracardiac echocardiography (ICE) to guide this procedure in a 13‐year‐old patient. Placing an intracardiac echocardiographic catheter in the left pulmonary artery facing upward, we readily visualized the precise anatomy of coarctation, measured the pressure gradient, and monitored the stent inflation process. This report suggests a new application of ICE for intervention with structural and vascular diseases other than interatrial septum. 相似文献

Lessons Learned
- A biweekly TAS‐102 plus BEV schedule in patients with heavily pretreated mCRC showed equivalent efficacy with less toxicity compared with the current schedule of TAS‐102 plus BEV combination.
- Biweekly TAS‐102 plus BEV combination could reduce unnecessary dose reduction of TAS‐102, maintain higher doses, and possibly be effective even in cases without chemotherapy‐induced neutropenia (CIN).
- The prespecified subgroup analysis of this study showed an obvious association between CIN within the first two cycles and prognosis of biweekly TAS‐102 plus BEV.
