We report a case of the clinical course and pathologic findings for a kidney transplant recipient with plasma cell-rich rejection (PCRR) accompanied by antibody-mediated rejection (ABMR).A 29-year-old man with end-stage renal disease caused by lupus nephritis received an ABO-compatible living kidney transplant.Eighteen months after transplantation, the patient presented with proteinuria and increased serum creatinine. An episode biopsy revealed severe tubulointerstitial infiltration with plasma cells accompanied by peritubular capillaritis and positive findings on immunofluorescent C4d staining. Donor-specific antibodies were positive for DR52, and the patient was subsequently diagnosed with PCRR accompanied by ABMR. Treatment was initiated with high-dose steroids, intravenous immunoglobulin, gusperimus hydrochloride, muronmonab antibody CD3, and rituximab. However, ABMR persisted and allograft failure developed 20 months after onset.We argue that PCRR accompanied by ABMR is a subtype of PCRR that can progress to allograft failure owing to persistent ABMR.

We report the clinical course and pathologic findings of a kidney transplant donor who was diagnosed with immunoglobulin A (IgA) nephropathy by means of preimplantation biopsy and was later treated with methylprednisolone and tonsillectomy.The patient was a 57-year-old woman who met the criteria for kidney donation and was accepted as a donor. Donor nephrectomy was performed, and the preimplantation biopsy revealed that the donor had IgA nephropathy. One month after the nephrectomy, the donors laboratory findings indicated proteinuria and hematuria. Because these findings indicated active IgA nephropathy, we decided to perform tonsillectomy and methylprednisolone pulse therapy. Soon after these treatments, the patients proteinuria and hematuria were no longer observed.Subclinical IgA nephropathy can be incidentally found on preimplantation biopsies of living kidney donors. As demonstrated in this case, IgA nephropathy can become exacerbated and requires therapeutic intervention after kidney donation. Informed consent and careful observation should be used before and after transplantation, even for donors who have been determined to be eligible for kidney donation.

Studies have revealed that patients who undergo preemptive kidney transplantation (PKT) have favorable prognoses compared with those who undergo kidney transplantation after the initiation of dialysis. The number of PKT cases performed worldwide has been increasing. The goal of this study was to determine the clinical characteristics of patients who may successfully receive PKT.A single-center, case-control study was conducted to determine the clinical factors that lead to referral for PKT.Between April 1, 2009, and August 1, 2015, a total of 118 patients underwent living donor kidney transplantation. Thirty of these patients had not undergone dialysis before their initial visit to the study hospital. Of these, 20 received kidney transplantation before and after dialysis initiation, respectively (group PKT+, successful PKT; group PKT-, failed PKT). The baseline characteristics at the primary visit were compared between groups. The median duration from the first visit to the study institution to PKT was 5.6 0.7 months. Serum creatinine (Cr) levels differed significantly between groups (PKT+ vs PKT-, 6.0 0.3mg/dL vs 7.5 0.5mg/dL; P= .03). The receiver-operating characteristic curves revealed that a serum Cr level >5.7mg/dL at the initial visit to the unit was a cutoff point for predicting the success of PKT (area under the curve, 0.721; P= .02).Our results indicate that PKT should be performed within 6 months of the initial visit to the transplant center. Serum Cr levels<5.7mg/dL predict successful PKT.

Atrial fibrillation is one of the most common arrhythmias in hemodialysis patients. We evaluated its clinical outcomes among hemodialysis patients with atrial fibrillation in Japan. Using data derived from the Japanese Dialysis Outcomes and Practice Patterns Study, we analyzed backgrounds and outcomes among hemodialysis patients with and without atrial fibrillation in Japan. Among 7002 hemodialysis patients, the prevalence of atrial fibrillation was 5.7% and the incidence was 0.2 per 100 patient-years. Atrial fibrillation was independently associated with all-cause mortality (hazard ratio, 1.32; 95% confidence interval, 1.02-1.71) and cardiovascular events (hazard ratio, 1.39; 95% confidence interval, 1.15-1.68), but not with stroke events (hazard ratio, 0.77; 95% confidence interval, 0.55-1.06) after adjustment for other variables. We conclude that patients with atrial fibrillation experienced higher mortality and more cardiovascular events than did patients without atrial fibrillation, although the risk of stroke was lower than expected.

A 34-year-old man with a history of rectal cancer was receiving oral chemotherapy [tegafur-uracil (UFT) with leucovorin]. He visited our hospital due to nausea and abdominal pain, and his laboratory data revealed the presence of urinary ketones, hyperglycemia and high anion gap metabolic acidosis, and HbA1c level of 6.8%. Accordingly, we diagnosed fulminant type 1 diabetes. The development of fulminant type 1 diabetes during chemotherapy for malignancy is a rare, but potentially fatal condition. Therefore, clinicians should consider diabetic ketoacidosis in the differential diagnosis when examining chemotherapy patients who present with gastrointestinal symptoms. © 2015 The Japanese Society of Internal Medicine.


We report the case of an effectively treated 50-year-old woman with liver metastasis of left breast cancer. Her breast cancer (T2N0M0, Stage IIA) was resected in November 1998 (radical mastectomy+axillary lymph nodes dissection). After this operation, tamoxifen(TAM 20 mg daily) was administered. In February 2002, a solitary liver metastasis(S5, 4 cm in diameter) was found by computed tomography(CT) scan. Hepatic arterial infusion of docetaxel(DOC 20 mg weekly)was started. In March 2003, the solitary liver metastasis had become smaller and showed partial remission (PR), but DOC intravenous injection(iv) therapy(40 mg weekly) was started because lung metastases appeared. Therefore, epirubicin+ cyclophosphamide therapy, DOC ia therapy (120 mg triweekly), and anastrozole (1 mg daily) were continued. However, in March 2005, she refused chemotherapy. In January 2011, a CT scan showed progressive disease of multiple liver and lung metastases. Nab-paclitaxel(PTX) iv therapy(400 mg triweekly) and exemestane(25 mg daily) were administered. In March 2012, a CT scan showed PR of the metastatic breast cancer. She has continued to receive nab-PTX iv therapy as an outpatient.

Auris Nasus Larynx | Year: 2010

Objective: For the purpose of an en bloc resection with sufficient margins, a wide surgical field is necessary. We have reported on the application of a facial dismasking flap for removals of craniofacial lesions in order to provide a better surgical field with less morbidity. In this paper, we are introducing a new method, which is called the "nasal downward swing approach". Methods: This approach is a modification of the facial dismaking flap, which elevates the nasal bone along with the facial skin. Results: This approach offers an extremely wide surgical field on the facial front, especially the nasal cavity, while keeping scarring or facial paresis down to a bare minimum. Conclusion: This approach helps to preserve the entire shape of the nasal bone in particular, therefore, a good surgical option for pediatric patients. © 2009.

Spinal meningeal cysts in the sacrum (SMC) are known to be occasionally symptomatic with low back pain as well as leg pain, but no distinct prevalence of this pathological entity including asymptomatic lesions has been described. This prospective study investigated the prevalence of SMCs based on magnetic resonance (MR) myelography in 102 consecutive Japanese women with gynecological problems, who underwent pelvic conventional MR imaging. Ten of 102 patients were suspected of being positive for SMC (9.8%), but pseudo-positive findings were possible. A high probability of positive SMC was found in 7/102 (6.9%). MR myelography was better to detect SMCs than conventional MR imaging. Multiplicity and female preponderance may be other features of SMC. The speculated prevalence of SMCs in Japanese females ranged from 6.9% to 9.8%.

We report a case of severe skin metastases of advanced right breast cancer in an 84-year-old woman. The tumor (T4bN3cM0, Stage III C)was resected in June 2011(BT+AX)after blood transfusion for severe anemia. Radiotherapy to the right chest wall and supraclavicular lymph nodes was performed, and adjuvant hormonal therapy was administered. Local recurrences in the skin of the right chest wall appeared and were resected in December 2011. Nine months later, continuous bleeding from the progressed, widespread skin metastases needed recurrent blood transfusion. After using Mohs paste twice, the bleeding stopped almost completely. Mohs paste was very useful for stopping bleeding in locally advanced, unresectable skin metastasis.

We report a case of lung and bone metastases of right advanced breast cancer in a 33-year-old woman. Her breast cancer (T4bN1M1, StageIV)was resected in December 2003 (mastectomy [BT] plus axillary lymph node dissection [AX]) after local arterial infusion therapy and subsequent systemic chemo-endocrine therapy was initiated and continued. In June 2007, a computed tomography (CT) scan revealed cardiac tamponade due to pericarditis carcinomatosa. Pericardiocentesis was performed, and the bloody effusion was drained immediately. Subsequently, the sysytemic chemo-endocrine therapy was modified. In 2009, multiple cerebellar metastases were discovered and treated via whole brain irradiation. In 2010, multiple liver metastases appeared, and they were treated by intravenous (IV) administration of nab-paclitaxel. In 2011, superior vena cava syndrome appeared gradually, and it was treated via venous metallic stenting. In 2012, epidural spinal cord compression appeared gradually, and it was treated via irradiation. In November 2012, the patient died because of lymphangitis carcinomatosa; her prognosis was good, as it was approximately 5 years after the pericardiocentesis.
