A 39-year-old female with multiple necrotic cutaneous ulcerations as a presenting finding of Granulomatosis with Polyangiitis(GPA)is reported.Failing to respond to initial immunosuppressant therapy revealed a complicating codiagnosis of alpha-antitrypson deficiency(AAD).We outline the importance of this clinical association and advise that AAD should be considered in all cases of GPA

Summary Adrenocortical carcinoma (ACC) is a rare malignancy with an incidence of 0.7–2.0 cases/million/year. A majority of patients present with steroid hormone excess or abdominal mass effects, and in 15% of patients ACC is discovered incidentally. We present a case of 30-year-old otherwise asymptomatic Caucasian male who presented with a testicular swelling. Subsequent imaging and investigations revealed disseminated sarcoidosis and an 11 cm adrenal lesion. An adrenalectomy was performed. Histological examination of the resected specimen confirmed an ACC and also demonstrated a thin rim of adrenal tissue containing non-caseating granulomas, consistent with adrenal sarcoid. Learning points This case highlights an unusual presentation of two uncommon diseases. This case also highlights how separate and potentially unrelated disease processes may occur concomitantly and the importance, therefore, of keeping an open mind when dealing with unusual diagnostic findings. We also hypothesize a potential link between the ACC and sarcoidosis in our patient.

Introduction Our hospital found itself at the epicentre of the Irish COVID-19 pandemic. We describe the organisational challenges faced in managing the surge and identified risk factors for mortality and ICU admission among hospitalised SARS-CoV-2-infected patients. Methods All hospitalised SARS-CoV-2 patients diagnosed between March 13 and May 1, 2020, were included. Demographic, referral, deprivation, ethnicity and clinical data were recorded. Multivariable regression, including age-adjusted hazard ratios (HR (95% CI), was used to explore risk factors associated with adverse outcomes. Results Of 257 inpatients, 174 were discharged (68%) and 39 died (15%) in hospital. Two hundred three (79%) patients presented from the community, 34 (13%) from care homes and 20 (8%) were existing inpatients. Forty-five percent of community patients were of a non-Irish White or Black, Asian or minority ethnic (BAME) population, including 34 Roma (13%) compared to 3% of care home and 5% of existing inpatients, (p < 0.001). Twenty-two patients were healthcare workers (9%). Of 31 patients (12%) requiring ICU admission, 18 were discharged (58%) and 7 died (23%). Being overweight/obese HR (95% CI) 3.09 (1.32, 7.23), p = 0.009; a care home resident 2.68 (1.24, 5.6), p = 0.012; socioeconomically deprived 1.05 (1.01, 1.09), p = 0.012; and older 1.04 (1.01, 1.06), p = 0.002 were significantly associated with death. Non-Irish White or BAME were not significantly associated with death 1.31 (0.28, 6.22), p = 0.63 but were significantly associated with ICU admission 4.38 (1.38, 14.2), p = 0.014 as was being overweight/obese 2.37 (1.37, 6.83), p = 0.01. Conclusion The COVID-19 pandemic posed unprecedented organisational issues for our hospital resulting in the greatest surge in ICU capacity above baseline of any Irish hospital. Being overweight/obese, a care home resident, socioeconomically deprived and older were significantly associated with death, while ethnicity and being overweight/obese were significantly associated with ICU admission.

The overdiagnosis of thyroid nodules and indolent thyroid cancers represents an increasing burden on health services, with thyroid ultrasound (US) imaging often representing the initial entry point into the thyroid nodule diagnostic pathway. The aim of this study was to retrospectively review thyroid US referrals to a single Irish hospital to determine if the stated indications for imaging had been appropriate, to review the results of the scans, and to assess the follow-up required in each case. Patient demographics, scan indications, results, and outcomes were retrospectively reviewed for all patients undergoing thyroid ultrasound from 2012 to 2016. Data were analyzed using GraphPad Prism and expressed in mean ± standard deviation. In total, 318 patients (mean age 53 ± 15 years, 85% female) had at least one ultrasound. Most US scans were performed for appropriate indications in order to follow up known thyroid nodular disease and/or malignancy (34.3%), to assess new thyroid goiters or discrete neck lumps (33.3%), and to follow up incidental findings from other imaging modalities (12.6%). However, scans were also requested (in the absence of any palpable goiter or mass) for choking/neck pain/swallowing complaints (12.3%), hypo/hyperthyroidism (6.6%), and miscellaneous reasons (0.6%) that were deemed either potentially or likely inappropriate. Of these scans, approximately half of the identified nodule(s) were deemed unlikely to be related to the stated symptoms, but which subsequently required follow-up imaging ± biopsy. No cases of malignancy were identified. In our center, a significant percentage of thyroid US scans along with their subsequent follow-up were potentially avoidable.

INTRODUCTION:Synovial chrondomatosis is a rare disorder characterised by the development of hyaline cartilage from the synovial membrane. Large isolated lesions in the Hoffa's fat pad are an uncommon entity. PRESENTATION OF CASE:A 33 year old gentleman presented complaining of progressive knee pain associated with an enlarging lesion on the anterior aspect of the right knee, with associated locking and giving way. Examination revealed a firm 4×5cm lesion adjacent to the patellar tendon. Subsequent CT and MRI demonstrated a lesion in the inferior aspect of Hoffa's fat pad, with a second lesion adjacent to the proximal tibiofibular joint, in addition to advanced degenerative changes and a meniscal tear. He proceeded to excisional biopsy. Histological analysis was consistent with a solitary synovial osteochondroma. There were no atypical features suggestive of malignancy. DISCUSSION:Synovial chondromatosis is a rare disorder affecting the synovial joints. The underlying pathophysiology is thought to be metaplastic change of the synovium to hyaline cartilaginous tissue. Transformation to malignancy has been described but is uncommon with an estimated risk of 5%. It is 1.5-2 times as prevalent in males versus females. Symptoms which patients may complain of include pain;locking and giving way; and palpable masses. The management usually entails removal of the mass lesion with or without accompanying synovectomy. Recurrence of disease may occur in up to 15-23% of patients. CONCLUSION:Synovial chrondromatosis is a rare but well recognised condition. Long term follow up is advised in view of the risk of recurrence and malignant transformation.

Background. The contribution of gastric acid to the toxicity of alkaline duodenal refluxate on the esophageal mucosa is unclear This study compared the effect of duodenal refluxate when acid was present, decreased by proton. pump inhibitors (PPI), or absent.Methods. We randomized 136 Sprague-Dawley rats into 4 groups: group 1 (n = 33) were controls; group 2 (n = 34) underwent esophagoduodenostomy promoting "combined reflux"; group 3 (n = 34) underwent esophagoduodenostomy and PPI treatment to decrease acid reflux; and group 4, the 'gastrectomy' group (n = 35) underwent esaphagoduodenostomy and total gastrectomy to eliminate acid in the refluxate. Esophaguses were examined for inflammatory, Barrett's, and other histologic changes, and expression of proliferative markers Ki-67, proliferating cell nuclear antigen (PCNA), and epidermal growth factor receptor (EGFR).Results. In all reflux groups, the incidence of Barrett's mucosa was greater when acid was suppressed (group C, 62%; group 1), 71%) than when not suppressed (group B, 27%; P = 0.004 and P < .001). Erosions were more frequent in the PPI and gastrectomy groups than in the combined reflux group. Edema (wet weight) and ulceration was more frequent in the gastrectomy than in the combined reflux group. Acute inflammatory changes were infrequent in the PPI group (8%) compared with the combined reflux (94%) or gastrectomy (100%) groups, but chronic inflammation persisted in 100% of the PPI group. EGFR levels were greater in the PPI compared with the combined reflux group (P = .04). Ki-67, PCNA, and combined marker scores were greater in the gastrectomy compared with the combined reflux group (P = .006, P = .14, and P < .001).Conclusion. Gastric acid suppression in the presence of duodenal refluxate caused increased rates of inflammatory changes, intestinal metaplasia, and molecular proliferative activity. PPIs suppressed acute inflammatory changes only, whereas chronic inflammatory changes persisted. (Surgery 2012;151:382-90.)
