Abstract
A 54-year-old man presents to the emergency department with acute onset left flank pain that radiates to the groin. A computed tomography scan of the abdomen/pelvis without contrast reveals a 7-mm distal ureteral stone. He is deemed appropriate for outpatient management. In addition to pain medications, should you prescribe tamsulosin?

Abstract
OBJECTIVE Sjögren's syndrome (SS) and systemic lupus erythematosus (SLE) are related by clinical and serologic manifestations as well as genetic risks. Both diseases are more commonly found in women than in men, at a ratio of ~10 to 1. Common X chromosome aneuploidies, 47,XXY and 47,XXX, are enriched among men and women, respectively, in either disease, suggesting a dose effect on the X chromosome. METHODS We examined cohorts of SS and SLE patients by constructing intensity plots of X chromosome single-nucleotide polymorphism alleles, along with determining the karyotype of selected patients. RESULTS Among ~2,500 women with SLE, we found 3 patients with a triple mosaic, consisting of 45,X/46,XX/47,XXX. Among ~2,100 women with SS, 1 patient had 45,X/46,XX/47,XXX, with a triplication of the distal p arm of the X chromosome in the 47,XXX cells. Neither the triple mosaic nor the partial triplication was found among the controls. In another SS cohort, we found a mother/daughter pair with partial triplication of this same region of the X chromosome. The triple mosaic occurs in ~1 in 25,000-50,000 live female births, while partial triplications are even rarer. CONCLUSION Very rare X chromosome abnormalities are present among patients with either SS or SLE and may inform the location of a gene(s) that mediates an X dose effect, as well as critical cell types in which such an effect is operative.

Abstract
BACKGROUND Off-label use of rituximab in lupus nephritis is reported to be beneficial. While the optimal dose is unknown, the regimen of four intravenous doses of 375 mg/m(2) is commonly employed, despite expense and potential side-effects. AIM To investigate the response to single-dose rituximab, added to standard corticosteroids plus additional immunosuppressive agent, in refractory lupus nephritis. METHODS Consecutive consenting patients with refractory lupus nephritis despite steroids plus either cyclophosphamide, mycophenolate or azathioprine were enrolled in this ethics-approved, open-label, prospective study. After baseline assessment, patients received one intravenous infusion of 375 mg/m(2) rituximab. Clinical, biochemical and serological (DsDNA, complement) responses to this dose were analysed. Complete renal response (CR) was defined as normalisation of creatinine, albumin, proteinuria and urinary RBCs and partial response (PR) as ≥50% improvement in at least one parameter, without deterioration in others. B-cell depletion was defined as peripheral CD19 lymphocyte count ≤0.05 × 10(9) /L. RESULTS Fourteen patients were enrolled in the study. All were B-cell-depleted until 8 months post-dose. Eleven patients (79%) responded (2CR, 9PR) at a median time of 5 months, with a 6-month probability of renal response of 43%. Five patients (45%) relapsed at a median time of 17 months. DsDNA titres decreased in 69%. Side-effects were minimal. CONCLUSIONS Single-dose rituximab is effective in relapsed/refractory lupus nephritis. Longevity of B-cell depletion with single-dose rituximab is similar to that of four doses with potentially fewer side-effects.

Abstract
The conflict in Syria has led to an unprecedented humanitarian crisis that extends across multiple countries in the area. Mental health services were undeveloped before and now face huge strain and unmet need. The World Health Organization and others have developed a programme to build capacity in the delivery of mental health services in an integrated healthcare package to refugees and displaced people. The tool used for this is the mhGAP Intervention Guide and complementary materials. In this paper we refer to training in Turkey, Iraq and Syria where health professionals were trained to roll out this community-based integrated approach through primary healthcare. We describe field case examples that show the complexity of situations that face refugees, displaced people and those caught in active conflict. Training improved the knowledge and skills for managing mental health disorders in primary healthcare. Further work needs to be done to demonstrate greater access to and utilisation of services, client outcomes and organisational change with this approach.

Abstract
Primary Sjögren's syndrome (pSS) has a strong female bias. We evaluated an X chromosome dose effect by analyzing 47,XXY (Klinefelter's syndrome, 1 in 500 live male births) among subjects with pSS. 47,XXY was determined by examination of fluorescence intensity of single nucleotide polymorphisms from the X and Y chromosomes. Among 136 pSS men there were 4 with 47,XXY. This was significantly different from healthy controls (1 of 1254 had 47,XXY, p=0.0012 by Fisher's exact test) as well men with rheumatoid arthritis (0 of 363 with 47,XXY), but not different compared to men with systemic lupus erythematosus (SLE) (4 of 136 versus 8 of 306, Fisher's exact test p=NS). These results are consistent with the hypothesis that the number of X chromosomes is critical for the female bias of pSS, a property that may be shared with SLE but not RA.

Abstract
OBJECTIVE More than 80% of autoimmune disease predominantly affects females, but the mechanism for this female bias is poorly understood. We suspected that an X chromosome dose effect accounts for this, and we undertook this study to test our hypothesis that trisomy X (47,XXX; occurring in ∼1 in 1,000 live female births) would be increased in patients with female-predominant diseases (systemic lupus erythematosus [SLE], primary Sjögren's syndrome [SS], primary biliary cirrhosis, and rheumatoid arthritis [RA]) compared to patients with diseases without female predominance (sarcoidosis) and compared to controls. METHODS All subjects in this study were female. We identified subjects with 47,XXX using aggregate data from single-nucleotide polymorphism arrays, and, when possible, we confirmed the presence of 47,XXX using fluorescence in situ hybridization or quantitative polymerase chain reaction. RESULTS We found 47,XXX in 7 of 2,826 SLE patients and in 3 of 1,033 SS patients, but in only 2 of 7,074 controls (odds ratio in the SLE and primary SS groups 8.78 [95% confidence interval 1.67-86.79], P = 0.003 and odds ratio 10.29 [95% confidence interval 1.18-123.47], P = 0.02, respectively). One in 404 women with SLE and 1 in 344 women with SS had 47,XXX. There was an excess of 47,XXX among SLE and SS patients. CONCLUSION The estimated prevalence of SLE and SS in women with 47,XXX was ∼2.5 and ∼2.9 times higher, respectively, than that in women with 46,XX and ∼25 and ∼41 times higher, respectively, than that in men with 46,XY. No statistically significant increase of 47,XXX was observed in other female-biased diseases (primary biliary cirrhosis or RA), supporting the idea of multiple pathways to sex bias in autoimmunity.

Abstract
BACKGROUND Dense deposit disease and atypical hemolytic uremic syndrome are often caused by Complement Factor H (CFH) mutations. This study describes the retinal abnormalities in dense deposit disease and, for the first time, atypical haemolytic uremic syndrome. It also reviews our understanding of drusen pathogenesis and their relevance for glomerular disease. METHODS Six individuals with dense deposit disease and one with atypical haemolytic uremic syndrome were studied from 2 to 40 years after presentation. Five had renal transplants. All four who had genetic testing had CFH mutations. Individuals underwent ophthalmological review and retinal photography, and in some cases, optical coherence tomography, and further tests of retinal function. RESULTS All subjects with dense deposit disease had impaired night vision and retinal drusen or whitish-yellow deposits. Retinal atrophy, pigmentation, and hemorrhage were common. In late disease, peripheral vision was restricted, central vision was distorted, and there were scotoma from sub-retinal choroidal neovascular membranes and atypical serous retinopathy. Drusen were present but less prominent in the young person with atypical uremic syndrome due to a heterozygous CFH mutation. CONCLUSIONS Drusen are common in forms of C3 glomerulopathy caused by compound heterozygous or heterozygous CFH mutations. They are useful diagnostically but also impair vision. Drusen have an identical composition to glomerular deposits. They are also identical to the drusen of age-related macular degeneration, and may respond to the same treatments. Individuals with a C3 glomerulopathy should be assessed ophthalmologically at diagnosis, and monitored regularly for vision-threatening complications.

Abstract
Defects in apoptosis can cause autoimmune disease. Loss-of-function mutations in the 'death receptor' FAS impair the deletion of autoreactive lymphocytes in the periphery, leading to progressive lymphadenopathy and systemic lupus erythematosus-like autoimmune disease in mice (Fas(lpr/lpr) (mice homozygous for the lymphoproliferation inducing spontaneous mutation)) and humans. The REL/nuclear factor-κB (NF-κB) transcription factors regulate a broad range of immune effector functions and are also implicated in various autoimmune diseases. We generated compound mutant mice to investigate the individual functions of the NF-κB family members NF-κB1, NF-κB2 and c-REL in the various autoimmune pathologies of Fas(lpr/lpr) mutant mice. We show that loss of each of these transcription factors resulted in amelioration of many classical features of autoimmune disease, including hypergammaglobulinaemia, anti-nuclear autoantibodies and autoantibodies against tissue-specific antigens. Remarkably, only c-REL deficiency substantially reduced immune complex-mediated glomerulonephritis and extended the lifespan of Fas(lpr/lpr) mice. Interestingly, compared with the Fas(lpr/lpr) animals, Fas(lpr/lpr)nfkb2(-/-) mice presented with a dramatic acceleration and augmentation of lymphadenopathy that was accompanied by severe lung pathology due to extensive lymphocytic infiltration. The Fas(lpr/lpr)nfkb1(-/-) mice exhibited the combined pathologies caused by defects in FAS-mediated apoptosis and premature ageing due to loss of NF-κB1. These findings demonstrate that different NF-κB family members exert distinct roles in the development of the diverse autoimmune and lymphoproliferative pathologies that arise in Fas(lpr/lpr) mice, and suggest that pharmacological targeting of c-REL should be considered as a strategy for therapeutic intervention in autoimmune diseases.

Abstract
Indirect inguinal hernias are the most commonly encountered congenital abnormality in infants. They may be complicated by herniation of abdominal or pelvic viscus. In girls, a herniated ovary is a relatively common finding, however torsion of the ovary is infrequent. A tender irreducible inguinal hernia in an infant girl should raise the possibility of a strangulated herniated ovary as it requires urgent surgical attention. When in doubt, ultrasound with colour Doppler easily confirms the diagnosis. Here we present the case of an ovarian inguinal hernia which had undergone torsion and review the presentation, imaging findings and management.

Abstract
Direct access referral for radiological investigations from General Practice (GP) provides an indispensable diagnostic tool and avoids the inherently long waiting time that referral through a hospital based specialty would entail. Improving access to hospital based radiology services is one of Health Information and Quality Authority's key recommendations in its report on patient referrals from general practice. This study aimed to review all GP referrals for ultrasound investigations to a tertiary referral teaching hospital over a seven month period with respect to their demographics, waiting times and diagnostic outcomes. 1,090 ultrasounds originating in general practice were carried out during the study period. Positive findings were recorded in 332 (30.46%) examinations. The median waiting time from receipt of referral to the diagnostic investigation was 56 days (range 16 - 91 years). 71 (6.5%) patients had follow-up imaging investigations while recommendation for hospital based specialty referral was made in 35 cases (3.2%). Significant findings included abdominal aortic aneurysms, metastatic disease and lymphoma. Direct access to ultrasound for general practitioners allows the referring physician to make an informed decision with regard to the need for specialist referral. We believe these findings help support the case for national direct access to diagnostic ultrasound for general practitioners.

Abstract
Cytomegalovirus (CMV) is a significant cause of morbidity, mortality and graft loss in solid organ transplantation (SOT). Treatment options for ganciclovir-resistant CMV are limited. We describe a case of ganciclovir-resistant CMV disease in a renal transplant recipient manifested by thrombotic microangiopathy-associated glomerulopathy. Adoptive T cell immunotherapy using CMV-specific T cells from a donor bank was used as salvage therapy. This report is a proof-of-concept of the clinical and logistical feasibility of this therapy in SOT recipients.

Abstract
ABO incompatible living donor renal transplantation (ABOi) can achieve outcomes comparable to ABO compatible transplantation (ABOc). However, with the exception of blood group A2 kidneys transplanted into recipients with low titer anti-A antibody, regimens generally include antibody removal, intensified immunosuppression and splenectomy or rituximab. We now report a series of 20 successful renal transplants across a range of blood group incompatibilities using conventional immunosuppression alone in recipients with low baseline anti-blood group antibody (ABGAb) titers. Incompatibilities were A1 to O (3), A1 to B (2), A2 to O (2), AB to A (2), AB to B (1), B to A1 (9), B to O (1); titers 1:1 to 1:16 by Ortho. At 36 months, patient and graft survival are 100%. Antibody-mediated rejection (AbMR) occurred in one patient with thrombophilia and low level donor-specific anti-HLA antibody. Four patients experienced cellular rejection (two subclinical), which responded to oral prednisolone. This series demonstrates that selected patients with low titer ABGAb can undergo ABOi with standard immunosuppression alone, suggesting baseline titer as a reliable predictor of AbMR. This reduces morbidity and cost of ABOi for patients with low titer ABGAb and increases the possibility of ABOi from deceased donors.

Abstract
FASL/FAS signaling imposes a critical barrier against autoimmune disease and lymphadenopathy. Mutant mice unable to produce membrane-bound FASL (FasL(Δm/Δm)), a prerequisite for FAS-induced apoptosis, develop lymphadenopathy and systemic autoimmune disease with immune complex-mediated glomerulonephritis. Prior to disease onset, FasL(Δm/Δm) mice contain abnormally high numbers of leukocytes displaying activated and elevated NF-κB-regulated cytokine levels, indicating that NF-κB-dependent inflammation may be a key pathological driver in this multifaceted autoimmune disease. We tested this hypothesis by genetically impairing canonical or non-canonical NF-κB signaling in FasL(Δm/Δm) mice by deleting the c-Rel or NF-κB2 genes, respectively. Although the loss of NF-κB2 reduced the levels of inflammatory cytokines and autoantibodies, the impact on animal survival was minor due to substantially accelerated and exacerbated lymphoproliferative disease. In contrast, a marked increase in lifespan resulting from the loss of c-REL coincided with a striking reduction in classical parameters of autoimmune pathology, including the levels of cytokines and antinuclear autoantibodies. Notably, the decrease in regulatory T-cell numbers associated with loss of c-REL did not exacerbate autoimmunity in FasL(Δm/Δm)c-rel(-/-) mice. These findings indicate that selective inhibition of c-REL may be an attractive strategy for the treatment of autoimmune pathologies driven by defects in FASL/FAS signaling that would be expected to circumvent many of the complications caused by pan-NF-κB inhibition.
