Prevalence and factors associated with lateral epicondylitis among hospital healthcare workers.

Background: Hospital healthcare workers have been reported to have a high prevalence of musculoskeletal disorders, but their association with lateral epicondylitis (LE) is unknown. This study aimed to clarify the prevalence of LE and its associated factors among hospital healthcare workers. Methods: The present study included all staff members of a secondary emergency hospital who provided their consent to participate. Participants with a history of elbow joint trauma were excluded from this study. The diagnostic criteria for definite LE were: (1) pain in the elbow joint within 2 weeks of the study; (2) pain in the lateral epicondyle region on resisted extension of the wrist with the elbow extended; and (3) tenderness in the lateral epicondyle. The diagnosis of LE was defined by meeting all criteria. Age, height, weight, sex, dominant hand, occupation, years of employment, smoking history, drinking history, personal computer usage history, and smartphone usage history were investigated using a questionnaire. A physical examination, in addition to evaluation of pain in the lateral epicondyle, grip strength and wrist extension strength were measured. A statistical analysis was used to assess the prevalence of LE and its associated factors. All investigations, including the diagnosis of LE, were performed by a single orthopedic specialist. Results: We evaluated 544 individuals, corresponding to approximately 80% of all staff members. The median age was 39 years (interquartile range, 30-48). The study population included 154 males and 390 females. The occupations of the participants were as follows: nurses (n = 265), doctors (n = 47), clerks (n = 93), therapists (n = 27), certified care workers (n = 23), medical technologists (n = 22), pharmacists (n = 19), and others (n = 48). LE was diagnosed in 30 limbs/30 individuals with a prevalence of approximately 5.5%. There was no difference in the prevalence of LE among occupations (P = .85). A logistic regression analysis revealed that age (odds ratio, 1.05; 95% confidence interval 1.01-1.1; P = .01) and smoking history (odds ratio, 2.94; 95% confidence interval 1.01-8.56; P = .04) were independently associated with LE. Conclusion: This study was conducted to evaluate the prevalence of LE among hospital healthcare workers. The prevalence of LE was 5.5%, and LE was independently associated with age and smoking history.

Successful Nonoperative Treatment of Osteochondritis Dissecans of the Humeral Capitellum in a Young Baseball Player with Advanced Skeletal Maturity.

BACKGROUND: Osteochondritis dissecans (OCD) of the humeral capitellum presents most typically in adolescent athletes who perform repetitive overhead activities. Earlier studies have demonstrated that conservative treatment of OCD is appropriate for patients with an open capitellar growth plate from the standpoint that spontaneous healing can be expected. CASE: A 12-year-old male baseball player with two years of experience with a local team participated in our medical check that included screening for capitellar OCD using ultrasonography. The subject experienced elbow pain when throwing, and ultrasonographic elbow examination indicated OCD of the capitellum, detected as irregularity of the subchondral bone of the capitellum. The initial radiograph, taken with the elbow at 45° of flexion, identified new bone formation in the lateral aspect of the OCD lesion; however the epiphyseal lines of the capitellum and lateral epicondyle were closed. We advised the patient to stop heavy use of the elbow, e.g., throwing and batting, and started conservative treatment in anticipation of spontaneous healing. Physiotherapy focusing on the shoulder girdle, core, and hip and lower limb stretches were performed to resolve general tightness. The OCD lesion had healed completely 12 months after the start of conservative treatment. DISCUSSION: Conservative treatment for young baseball players might be worth considering if lateral new bone formation within the OCD lesion is detected on radiographic findings, even if the epiphyseal lines of the capitellum and lateral epicondyle are closed.

Risk Factors for Throwing-Related Shoulder and Elbow Pain in Adolescent Baseball Players: A Prospective Study of Physical and Developmental Factors.

BACKGROUND: Throwing-related shoulder and elbow pain continues to be reported among adolescent baseball players. Few prospective studies have specifically examined the association between throwing-related shoulder and elbow pain and physical and developmental changes. PURPOSE: To evaluate the changes in physical and developmental characteristics during 1 year with respect to throwing-related shoulder and elbow pain in adolescent baseball players. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This 1-year prospective follow-up study investigated 164 baseball players aged 7 to 13 years. Player data (age, height, weight, field position, and pitch count), lower extremity muscle tightness, and range of motion (ROM) of the shoulder, elbow, and hip joints were assessed during the 2016 and 2017 preseason medical examinations. After the 2016 season, the participants completed questionnaires related to throwing-related shoulder and elbow pain, defined as an inability to play for ≥1 week because of elbow or shoulder difficulties. For study participants with and without throwing-related shoulder or elbow pain during the 2016 season, we conducted univariate and multivariate logistic regression analysis to identify risk factors for throwing-related shoulder or elbow pain. RESULTS: Overall, 21 players (12.8%) reported a shoulder pain episode, 56 players (34.1%) had an elbow pain episode, and 70 players (42.7%) reported having experienced shoulder and/or elbow pain during the 2016 season. In multivariate logistic regression analysis, (1) shoulder pain was associated with 2016 preseason height (odds ratio [OR], 1.06; 95% CI, 1.01-1.11; P = .01) and change in dominant-side elbow extension ROM from 2016 to 2017 (OR, 1.12; 95% CI, 1.02-1.24; P = .02); (2) elbow pain was associated with change in weight from 2016 to 2017 (OR, 1.21; 95% CI, 1.04-1.41; P = .014); and (3) throwing-related shoulder and/or elbow pain was associated with greater 2016 preseason height (OR, 1.04; 95% CI, 1.003-1.68; P = .03) and an increase in height from 2016 to 2017 (OR, 1.17; 95% CI, 1.01-1.35; P = .03). CONCLUSION: Our results indicated that adolescent baseball players who were taller in the preseason and those with an increase in height over the 1-year study period faced significant risks for developing throwing-related shoulder and/or elbow pain.

Collagenase Clostridium histolyticum Injection Therapy Improves Health-related Quality of Life in Patients with Dupuytren's Disease.

OBJECTIVES: This study was conducted to investigate the changes in clinical and psychosocial outcomes in patients with Dupuytren's disease after initial treatment with collagenase Clostridium histolyticum (CCH) injection. METHODS: This study involved 14 patients with Dupuytren's disease who underwent treatment with CCH injection. The range of motion of each phalangeal joint was measured before treatment and at 6 months posttreatment. The following assessments were also carried out pre- and posttreatment: the Geriatric Depression Scale Short - Japanese version (GDS-J) to evaluate depressive status, Hand 10 to assess hand health status, and EuroQol-5-dimension-3-level Japanese version to evaluate health-related quality of life. RESULTS: Significant improvements were found in metacarpophalangeal joint extension and proximal interphalangeal joint extension. Significant differences were also found between values before the initiation of CCH injection and those at 6 months posttreatment for the EuroQol index score and the EuroQol Visual Analog Scale (VAS). Significant positive correlations were found between the pre- to posttreatment change in GDS-J scores and for the change in Hand 10 scores. Moreover, a significant negative correlation was found between the change in GDS-J scores and change in EuroQol index scores/EuroQol VAS scores before and at 6 months after CCH injection. CONCLUSIONS: For patients with Dupuytren's disease, CCH therapy directly improved the health-related quality of life. The degree of improvement of depressive status was associated with the degree of improvement of hand health status and health-related quality of life.

A Clinical Trial With Adoptive Transfer of Ex Vivo-induced, Donor-specific Immune-regulatory Cells in Kidney Transplantation-A Second Report.

BACKGROUND: Although the outcome of kidney transplantation (KTx) has improved, various adverse effects of immunosuppressants and chronic rejection aggravate the long-term prognosis of patients. Therefore, the induction of immune tolerance may be an effective therapeutic strategy. METHODS: A clinical trial aiming at immune tolerance induction was conducted in kidney transplant recipients from HLA mismatched living donors by infusing autologous donor-specific regulatory T cells (Treg). To obtain Treg, recipient's peripheral blood mononuclear cells were cocultured with irradiated donor cells in the presence of anti-CD80/CD86 monoclonal antibody for 2 weeks. For preconditioning, splenectomy + cyclophosphamide (CP) was employed in the first series (group A; n = 9). In group B, splenectomy was substituted by preadministration of rituximab (group B; n = 3). In the latest cases, rituximab + rabbit antithymocyte globulin was administered instead of cyclophosphamide (group C; n = 4). Twelve days after KTx, the cultured cells were intravenously infused, and immunosuppressants were gradually tapered thereafter. RESULTS: Although mixed lymphocyte reaction was remarkably suppressed in a donor-specific fashion, 6 out of 9 patients from group A, 1 out of 3 from group B, and 1 out of 4 from group C developed acute rejection within 1 year after KTx. Complete cessation of immunosuppression was not achieved, and a small dose of immunosuppressants was continued. CONCLUSIONS: The adoptive transfer of autologous ex vivo-expanded Treg is 1 of the options to possibly induce alloimmune hyporesponsiveness. However, in the present study, further regimen optimization is still required and should be the focus of future investigations.

Early Steroid Withdrawal Protocol With Basiliximab and Rituximab in ABO-Incompatible Kidney Transplant Recipients.

OBJECTIVES: Corticosteroids remain an important component of immunosuppressive regimens in high-risk kidney transplants. In this study, we investigated the efficacy of early steroid withdrawal with basiliximab and rituximab in ABO-blood type incompatible (ABO-i) recipients of kidney transplants. METHODS: Between 2008 and 2019, 15 patients underwent ABO-i kidney transplantation. Seven of the 15 patients were treated with a steroid maintenance protocol and the remaining 8 with an early steroid withdrawal protocol. The immunosuppressive protocol consisted of tacrolimus, mycophenolate mofetil, and methylprednisolone (MP), with basiliximab administered as induction therapy. Rituximab was administered as a single 200-mg dose 1 to 4 weeks before kidney transplantation. Two to 4 sessions of either double-filtration plasmapheresis or regular plasmapheresis or both were performed to remove anti-AB antibodies before transplantation. During surgery, MP was administered at a dose of 500 mg; thereafter, the dosage was tapered rapidly, and the drug was discontinued on day 14 post transplant. RESULTS: In the steroid maintenance group, 2 patients experienced acute antibody-mediated rejection (AMR). One patient with severe AMR had graft loss on postoperative day 4. Patient and graft survival rates in the steroid maintenance group were 100% and 86%, respectively. MP was successfully withdrawn in the steroid withdrawal group. In this group, there was no biopsy-proven rejection. Patient and graft survival rates were 100%, and when last measured, serum creatinine level ± SD was 1.6 ± 0.8 mg/dL. CONCLUSIONS: Our protocol successfully enabled the early withdrawal of steroids in recipients of ABO-i grafts; however, further follow-up is necessary to confirm our results.

Preoperative assessment system for hand-assisted laparoscopic donor nephrectomy by discriminant analysis.

We developed a preoperative assessment system to predict surgical workload in hand-assisted laparoscopic donor nephrectomy (HALDNx) using the normal-based linear discriminant rule (NLDR). A total of 128 cases of left HALDNx performed by a single operator were used as training data. Surgical workload was measured by operative time. The optimized model had 9 explanatory variables: age, total protein, total cholesterol, number of renal arteries (numberRA), 4 variables of perinephric fat (PNF), and thickness of subcutaneous fat. This model was validated using cross-validation and the .632 estimator to estimate discrimination rates with future test data. PNF and numberRA were the predominant factors affecting workload followed by the computed tomography value of PNF, body weight, and male sex. The estimated accuracy of the prediction system was 94.6%. The complication rate was 9.38% and did not correlate with surgical workload. We also made our program available online for constructing assessment functions from other cohort data. In conclusion, the surgical workload of HALDNx could be predicted with PNF and numberRA as the dominant risk factors.

Single fixed low-dose rituximab as induction therapy suppresses de novo donor-specific anti-HLA antibody production in ABO compatible living kidney transplant recipients.

This study was conducted to evaluate de novo donor-specific anti-human leukocyte antigen (HLA) antibody (dnDSA) production leading to antibody-mediated rejection (ABMR) after rituximab induction in non-sensitized ABO-compatible living kidney transplantation (ABO-CLKTx). During 2008-2015, 318 ABO-CLKTx were performed at the Department of Surgery III at Tokyo Women's Medical University Hospital. To reduce confounding factors, we adopted a propensity score analysis, which was applied with adjustment for age, gender, duration of pretransplant dialysis, HLA mismatch count, preformed DSA, non-insulin-dependent diabetes mellitus, immunosuppressive treatment, and estimated glomerular filtration rate (eGFR) on postoperative day 7. Using a propensity score matching model (1:1, 115 pairs), we analyzed the long-term outcomes of 230 ABO-CLKTx recipients retrospectively. Recipients were classified into a rituximab-treated (RTX-KTx, N = 115) group and a control group not treated with rituximab (C-KTx, N = 115). During five years, adverse events, survival rates for grafts and patients, and incidence of biopsy-proven acute rejection (BPAR) and dnDSA production for the two groups were monitored and compared. All recipients in the RTX-KTx group received rituximab induction on preoperative day 4 at a single fixed low dose of 100 mg; the CD19+ B cells were eliminated completely before surgery. Of those recipients, 13 (11.3%) developed BPAR; 1 (0.8%) experienced graft loss. By contrast, of C-KTx group recipients, 25 (21.7%) developed BPAR; 3 (2.6%) experienced graft loss. The RTX-KTx group exhibited a significantly lower incidence of BPAR (P = .041) and dnDSA production (13.9% in the RTX-KTx group vs. 26.9% in the C-RTx group, P = .005). Furthermore, lower incidence of CMV infection was detected in the RTX-KTx group than in the C-KTx group (13.9% in the RTX-KTx group vs. 27.0% in the C-KTx group, P = .014). No significant difference was found between groups for several other factors: renal function (P = .384), graft and patient survival (P = .458 and P = .119, respectively), and the respective incidences of BK virus infection (P = .722) and leukopenia (P = .207). During five-year follow-up, single fixed low-dose rituximab therapy is sufficient for ensuring safety, reducing rejection, and suppressing dnDSA production for immunological low-risk non-sensitized ABO-CLKTx.

Trough Level of Mycophenolic Acid Did Not Affect De Novo DSA Development in Kidney Transplantation.

INTRODUCTION: Mycophenolate mofetil has improved long-term outcomes of kidney transplantation. However, the impact of mycophenolic acid (MPA) trough level on the development of de novo donor-specific anti-HLA antibody (DSA) is unclear. We examined the relation between MPA trough level and de novo DSA development. METHOD: We retrospectively studied 617 kidney recipients whose MPA trough level and de novo DSA data were available. All patients underwent primary kidney transplant from living donors from 2008 to 2014, and were chronically treated with a calcineurin inhibitor, mycophenolate mofetil, and +/- steroids. They were equally divided into 4 groups according to the mean trough level of MPA (mMPA) at 1 year post-transplantation: Group 1, mMPA < 2.14 ng/mL (n = 152); Group 2, mMPA 2.14-2.83 ng/mL (n = 157); Group 3, mMPA 2.83-3.57 ng/mL (n = 153); and Group 4, mMPA ≥ 3.57 ng/mL (n = 155). The groups were compared by incidence rate of de novo DSA, graft survival rate, and renal function. RESULTS: The incidence rates of de novo DSA were 33.3% in Group 1, 23.7% in Group 2, 22.9% in Group 3, and 30.3% in Group 4 (P = .158). Although there was no significant difference in graft survival rates, a significant difference of renal functions was noted: the higher the renal function, the lower the MPA trough level. CONCLUSION: The mMPA trough level at 1 year post-transplantation was not statistically associated with the incidence rate of de novo DSA after kidney transplantation.

Primary Nonfunction on Kidney Transplant Recipients From Donation After Circulatory Death Donors.

BACKGROUND: The need for donor pool expansion remains an important task for kidney transplantation. The aim of this study is the evaluation of primary nonfunction (PNF) from donation after circulatory death (DCD) kidneys. METHODS: Between 1996 and 2017, 100 kidney transplants from DCD donors were conducted in our department. We retrospectively analyzed PNF of kidney transplant recipients from DCD donors in terms of donors' and recipients' epidemiologic characteristics. RESULTS: Of 100 grafts, 95 recipients (95.0%) had discontinued hemodialysis at the time of hospital discharge. Only 5 recipients (5.0%) developed PNF. All 5 PNF recipients received a single graft from an expanded criteria donor (ECD). The mean donor age in the PNF group was 65.0 (SD, 6.2) years. Significant differences between the PNF group and discontinued dialysis group were found for donor age (P < .01) and for the use of ECD kidneys (P < .02). Nevertheless, no significant difference was found between groups for several factors: a history of hypertension and cerebrovascular events, terminal creatinine levels, and graft weight. CONCLUSION: The incidence of PNF from DCD kidneys was very low. Although ECD kidneys in older donors might be a significant risk factor for PNF, these findings suggest that DCD kidneys should be used more frequently for donor expansion.

Single Graft Utilization From Donors With Severe Acute Kidney Injury After Circulatory Death.

Chronic shortages of organs for transplantation have led to the use of marginal kidneys from donors after circulatory death with acute kidney injury (AKI), but the utilization of kidneys with severe AKI is not well established. We retrospectively analyzed eight kidney transplantation (KTx) cases from donation after circulatory death (DCD) with terminal creatinine (t-Cr) concentrations higher than 10.0 mg/dL and/or oliguria for more than 5 days (AKI network criteria: stage III). Although all patients showed delayed graft function, no cases of primary nonfunction (PNF) were found. Five patients maintained stable renal function for approximately 15.5, 10, 10, 5, and 0.5 years after KTx. Only 1 patient showed biopsy-proven acute rejection. Also, 2 patients developed graft failure: one attributable to chronic antibody mediated rejection at 11.3 years after KTx, and one attributable to recurrence of IgA nephropathy at 4.6 years after KTx. Kidneys with AKI stage III yielded great outcomes without the risk of primary nonfunction and rejection. Although the AKI kidneys were associated with delayed graft function, these results suggest that even the most severe kidneys with AKI stage III from DCD donors can be considered a valid alternative for recipients on a waiting list for KTx.

Preoperative Low-Density Lipoprotein Apheresis for Preventing Recurrence of Focal Segmental Glomerulosclerosis after Kidney Transplantation.

BACKGROUND: Focal segmental glomerulosclerosis (FSGS) often develops rapidly and frequently progresses to renal failure, while the recurrence rate after kidney transplantation is 20-50%. We performed low-density lipoprotein (LDL) apheresis before kidney transplantation in FSGS patients to prevent recurrence. METHODS: Five adult patients with chronic renal failure due to FSGS undergoing living related donor kidney transplantation were investigated retrospectively. LDL apheresis was done 1-2 times before transplantation. Postoperative renal function and recurrence of FSGS were assessed. RESULTS: The patients were two men and three women aged 24 to 41 years. The observation period ranged from 60 days to 22 months. Preoperative LDL apheresis was performed once in one patient and twice in four patients. Blood LDL cholesterol levels were normal before LDL apheresis and remained normal both after LDL apheresis and after kidney transplantation. Additional LDL apheresis was performed once in one patient with mild proteinuria after transplantation. The renal graft survived in all patients and there was no evidence of recurrent FSGS. CONCLUSIONS: Although the observation period was short, FSGS did not recur in all 5 patients receiving preoperative LDL apheresis. These results suggest that LDL apheresis can be effective in preventing recurrence of FSGS after kidney transplantation.

Duodenal Graft Perforation after Simultaneous Pancreas-Kidney Transplantation.

A 45-year-old woman with type 1 diabetes and chronic renal failure on dialysis underwent simultaneous pancreas-kidney transplantation from a brain dead donor. On postoperative day 15, acute generalized peritonitis was diagnosed and emergency laparotomy was performed. Perforation of the donor duodenum was found, which had apparently resulted from duodenal compression by the tip of the intestinal fistula tube placed for decompression. The perforation was sutured and the intestinal fistula tube was exchanged. Following this, perforation repeatedly recurred at the same site and open repair at laparotomy was required a total of four times. The fourth operation involved both suturing the perforation and covering it with ileum, after which there was no further recurrence. The patient was discharged on posttransplantation day 219, with the pancreas and kidney grafts both functioning well. This report presents a rare complication of simultaneous pancreas-kidney transplantation.

Longterm renal allograft survival after sequential liver-kidney transplantation from a single living donor.

Combined liver-kidney transplantation (CLKT) is well established as a definitive therapy with the potential to provide complete recovery for certain liver-kidney diseases, although the results might be contingent on the cause of transplantation. The purposes of the present study were to review the longterm outcome of renal allografts in CLKT patients from single living donors and to investigate the beneficial factors, compared with solitary renal transplantation. Thirteen patients underwent sequential liver transplantation (LT) and kidney transplantation (KT) from single living donors. The indications for KT were oxaluria (n = 7), autosomal recessive polycystic disease (n = 3), and others (n = 3). The same immunosuppressive regimen used after LT was also used after KT. KT was performed between 1.7 and 47.0 months after the LT. The overall patient survival rate was 92.3% at 10 years. In 12 of the 13 surviving patients, the renal allografts were found to be functioning in 11 patients after a mean follow-up period of 103.6 months. The death-censored renal allograft survival rate at 10 years was 100%, which was better than that of KT alone (84.9%) in Japan. Immunological protection conferred by the preceding liver allograft may have contributed to the longterm outcomes of the renal allografts. In addition, the donation of double organs from a single living and related donor may have a favorable impact on the graft survival rate. In the future, investigations of factors affecting the longterm outcome of renal allografts, including details of the involvement of de novo donor-specific antibody, will be needed.

Quality of life in Japanese patients with type 1 diabetes and end-stage renal disease undergoing simultaneous pancreas and kidney transplantation.

We conducted this cross-sectional study to assess quality of life (QOL) in Japanese patients with type 1 diabetes mellitus (T1DM) and end-stage renal disease (ESRD) undergoing simultaneous pancreas and kidney transplantation (SPK). Japanese patients with T1DM without diabetic nephropathy (N = 10), and those undergoing chronic dialysis (N = 52), kidney transplantation alone (KTA, N = 25), and SPK (N = 16) were studied. Comprehensive health-related QOL was assessed using the Short Form 36 version 2 (SF-36v2). Emotional functioning in diabetes was measured by the Problem Area In Diabetes (PAID) scale. Severity of impaired hypoglycemic awareness was assessed using the Clarke hypoglycemic score. SPK patients had significantly higher (or tended to have higher) subscale and summary SF-36 scores than dialysis patients and KTA patients. PAID scores were significantly lower in SPK patients than in dialysis patients and KTA patients. Clarke hypoglycemic scores were also significantly lower in SPK patients than dialysis patients. In KTA and dialysis patients, there were no significant differences in the SF-36 subscale/summary scores, PAID scores, or Clarke hypoglycemic scores. In conclusion, QOL for Japanese patients receiving SPK may be superior to that of dialysis patients and KTA patients. Whether SPK actually improves QOL needs to be clarified in longitudinal studies.

Successful Long-term Graft Survival of a Renal Transplantation Patient with Wiskott-Aldrich Syndrome.

Wiskott-Aldrich syndrome, a rare X-linked hereditary syndrome, is characterized by immunodeficiency, thrombocytopenia, and eczema. The underlying T-cell defect renders renal transplantation and immunosuppressive treatments uncertain. The present case exhibited the mild clinical manifestation, regarded as X-linked thrombocytopenia. He successfully underwent a living-donor ABO-compatible renal transplantation and splenectomy in 2002, and thereafter experiencing no severe rejection, serious infection, or malignancy for more than 10 years. Though IgA nephropathy was detected 8 months after transplantation, the patient's renal function and proteinuria were stable without any treatment. The present case showed a successful long-term graft survival and the importance of splenectomy added to renal transplantation.

Outcomes of Kidney Transplantation from Circulatory Death Donors With Increased Terminal Creatinine Levels in Serum.

BACKGROUND: To alleviate chronic renal graft shortages in Japan, donation after circulatory death (DCD) is an increasingly used organ resource. Organs from DCD donors with progressively increased terminal creatinine (t-Cr) levels are frequently used, but the effects of this condition on kidney transplantation (KTx) remain unclear. METHODS: Between 1996 and 2013, 99 KTx from DCD donors were conducted in our department. Recipients were grouped according to the t-Cr (in mg/dL) of donors: group 1, t-Cr less than < 1.5; group 2, 1.5 ≤ t-Cr < 3.0; and group 3, t-Cr ≥ 3.0. We analyzed the long-term outcomes of KTx from DCD donors retrospectively in terms of donors' terminal renal function. RESULTS: The respective mean donor t-Cr in groups 1, 2, and 3 were 0.73 ± 0.28, 2.02 ± 0.40, and 6.69 ± 3.68. The respective death-censored graft survival rates (%) in groups 1, 2, and 3 were 90.2, 96.2, and 86.7 at 1 year and 70.3, 86.2, and 73.4 at 10 years after transplantation. Group 1 exhibited lower incidence of delayed graft function than either group 2 or group 3 (80.5% vs 100% and 93.3%). Nevertheless, no significant difference was found between groups for several measures: Cr levels 1 month after KTx and lowest Cr levels throughout the observation period, prevalence of biopsy-proven acute rejection, and graft survival. Cox proportional hazard regression showed that donor age, cerebrovascular event, terminal urine output, and history of hypertension were significantly associated with graft survival. CONCLUSIONS: Results suggest that, under certain conditions, kidneys from DCD donors with progressively increased t-Cr can be used safely with promising long-term outcomes.

Assessment of quality and interpretation of panoramic radiographs obtained in the Lao People's Democratic Republic as part of a teleradiology collaboration with Japan.

As part of quality assessment of a teleradiology program we evaluated the validity of patient information received, the quality of panoramic radiography imaging in Laos, and the ability of a Laotian radiologist to detect temporomandibular joint abnormalities. The amount of patient information gathered from 2,021 scans of panoramic radiographs was evaluated by triage before image diagnosis. Among the radiographs from 2,021 patients, primary triage indicated that there was insufficient information for 794 (39.3%) patients. Secondary triage to assess imaging failure included 1,227 radiographs, four of which were excluded from imaging diagnosis because of unacceptable image flaws. In total, 2,446 joints from 1,223 radiographs were evaluated for temporomandibular joint abnormalities in order to compare the image interpretation abilities of Laotian and Japanese radiologists. The kappa coefficient was 0.836 (P < 0.01) for the agreement between the two observers in detecting temporomandibular joint abnormalities on radiographs. We conclude that additional efforts are needed in order to overcome the challenges of maintaining quality in imaging techniques and diagnoses in Laos.

Vascular access infection: survival or mortality.

METHODS: We conducted an analysis on 11 cases of death after AVG infection that occurred between 1996 and 2013, and compared their information with those of 23 cases of generalized infection due to arteriovenous graft (AVG) infection during the same period who survived. RESULTS: The cause of death was sepsis in all 11 patients. The initial C-reactive protein (CRP) was 10.2-39.8 (28 in average) and the duration from onset of fever to vascular access (VA) hemostasis/removal procedure was 6-9 days (6.4 days in average) in the 11 cases of death. Blood culture revealed a high frequency of methicillin-resistant staphylococcus aureus (MRSA) in 7 of the 11 cases of death. In contrast, in 23 survivors with VA infection and generalized infection, the CRP at the initial visit was 3.2-15.8 (5.6 in average) and the duration from onset of the fever to VA hemostasis/removal procedure was 0-5 days (2.6 days in average), and blood culture revealed a high frequency of methicillin-sensitive staphylococcus aureus (MSSA). Among the cases of death, although VA infection in the upper extremity itself resolved after removing the artificial vessel, they died without an improvement of sepsis. The reason why the sepsis did not resolve is that infectious foci were secondarily formed in other areas than the upper extremity because the start of treatment for VA infection was delayed. CONCLUSIONS: Treatment for VA infection should be started as early as possible after onset to avoid the formation of secondary infectious foci in other areas.

A case of cryopyrin-associated periodic syndrome with kidney transplant failure.

The cryopyrin-associated periodic syndrome (CAPS) is an autosomal dominant autoinflammatory disease characterized by fever, skin rash, and joint involvement with acute inflammatory response. The genetic defect involves the NLRP3 gene that encodes cryopyrin and leads to an abnormal production of interleukin-1 (IL-1). Therefore, anti-IL-1 treatment represents an effective therapy. One of the most severe manifestations of the disease is secondary amyloidosis that causes renal failure. We present a patient with CAPS who underwent renal transplantation for renal insufficiency caused by amyloidosis. The function of the transplanted kidney deteriorated because of the late administration of IL-1 receptor antagonist, anakinra. This case may indicate the importance of early initiation of anti-IL-1 treatment in CAPS patients who have undergone kidney transplantation.
