Abstract
BACKGROUND Skin cancer is common after solid organ transplantation, but few have investigated it after lung transplant (LTx). OBJECTIVE We assessed incidence and predictors of non-melanoma skin cancer (NMSC) post-LTx. METHODS We studied patients who underwent LTx at our center from 2012 to 2015. RESULTS Of 287 patients, mean age was 59.6 ± 11 years, 170 (59.2%) were men, and 231 (80.5%) were white. Seventy-six (26.5%) developed NMSC over a median follow-up of 32 months (IQR, 23-45). Of those with NMSC, 37% developed subsequent skin cancer of the same type. Independent predictors of decreased odds of NMSC and squamous cell carcinoma (SCC) were non-white race (P = .002; P = .003) and body mass index >30 kg/m2 compared with underweight patients (P = .001, P = .009). Patients with skin cancer pre-LTx had higher risk of post-LTx skin cancer (P = .02). Voriconazole use ≥100 days was associated with increased risk of SCC (P = .03), but not increased risk of basal cell carcinoma. Out of 76, 4 (5.3%) died from skin cancer. LIMITATIONS Retrospective, single-center study. CONCLUSION Squamous cell carcinoma risk post-LTx may increase with prolonged voriconazole use in white patients with pre-LTx history of skin cancer, whereas excess body weight may be protective from NMSC. Regular pre- and post-LTx skin cancer screenings and guidelines are warranted.

Abstract
Abstract
Background
Studies comparing the outcome of percutaneous coronary intervention (PCI) along with optimal medical therapy (OMT) versus OMT alone in treatment of chronic total occlusion (CTO) are limited by observational design, variable follow up period, diverse clinical outcome, high drop-out and cross-over rate. Prematurely terminated DECISION CTO trail and the promising result of the most recent EUROCTO trial still left the quest unanswered. Previous metanalysis on the present context were restricted to studies with propensity-matched analysis only and did not incorporate the recent randomized trials.
Purpose
This study aims to conduct a meta-analysis of published data of observational as well as randomized studies comparing long term outcomes of PCI+OMT versus OMT alone.
Methods
The present protocol is registered in PROSPERO. PubMed, Embase and Cochrane databases were systematically reviewed. Fourteen studies meeting criteria were included in the meta-analysis. The Cochrane Risk of Bias scale was used to appraise the overall quality of the studies. Revman 5.3 software was used to analyse the data and random-effects model with inverse variance method was undertaken. R packages were used for assessment of bias and metaregression.
Results
Baseline parameters of both the groups were comparable. Major adverse cardiovascular events (MACE) which comprises of cardiac death, myocardial infarction, stroke, and unplanned revascularization [Figure 1] were significantly lower in the PCI+OMT group. (RR: 0.77; 95% CI: 0.61 to 0.97; P≤0.ehz746.00521; I2=85%). High heterogeneity was partially (14%) explained by age factor. However study design, follow up duration, LVEF, presence of TVD did not attribute significantly to heterogeneity, in isolation or any combination in metregression model. All cause mortality and cardiac death [Figure 2, 3 respectively] were significantly lower in the PCI+OMT group (P=0.29, p=0.63, respectively). Myocardial infarction (P=0.25) and stroke rates (P=0.15) were lower in the PCI+OMT group, however they did not reach statistical significance. Unplanned revascularization (of any vessel) showed a higher trend in the PCI+OMT group, without reaching statistical significance (P=0.46, I2=88%).
Conclusion
PCI of CTO is rewarded with better long term outcome, in terms of MACE and all-cause mortality but limited to greater unplanned revascularization.

Abstract
CASE PRESENTATION A 47-year-old man who was a redo double lung transplant recipient (cytomegalovirus [CMV] status: donor positive/recipient positive; Epstein-Barr virus status: donor positive/recipient positive) presented to the hospital with 1 week of generalized malaise, low-grade fevers, and dry cough. His redo lung transplantation was necessitated by bronchiolitis obliterans syndrome, and his previous lung transplantation 5 years earlier was for silicosis-related progressive massive fibrosis. He denied any difficulty breathing or chest pain. There was no history of GI or urinary symptoms, and the patient had no anorexia, weight loss, night sweats, sick contacts, or history of travel. He had a history of 1 earlier episode of CMV viremia that was treated with valganciclovir. His immunosuppressive regimen included tacrolimus, mycophenolate mofetil, and prednisone, and his infection prophylaxis included trimethoprim-sulfamethoxazole, itraconazole, and valganciclovir. Results of a chest radiograph 8 weeks earlier were normal.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 inhibitors are novel antidiabetes drugs that act via inhibition of renal glucose reabsorption. This action causes osmotic diuresis, reduces intravascular volume and is associated with various adverse effects. In the present paper, we describe the first report on the unmasking of underlying polycythemia vera by canagliflozin in a person with Type 2 diabetes mellitus, which was temporally related to the use of the drug. CASE REPORT A 51-year-old obese man with Type 2 diabetes was prescribed canagliflozin 100 mg for control of his glycaemia. He presented 6 months later with asymptomatic elevation of his haemogram measurements (haemoglobin: 16.9 g/dl; haematocrit: 55%; red cell number: 8.1 million/mm3 ; total leukocytes: 23010/mm3 ; platelet count: 9.7 *106 /mm3 ). He had no history of smoking, exposure to high altitude or other drugs. Subsequent investigations revealed myeloproliferative neoplasm (polycythemia vera) on trephine biopsy of bone marrow, normal erythropoietin level and JAK2V617F positivity. Because of the possibility that the underlying condition had been unmasked by canagliflozin, the latter was stopped. This led to a remarkable improvement in the man's haematological profile, with no other significant intervention. The man subsequently restarted the drug of his own accord, causing his haematological profile to worsen again and thereby posing a challenge in monitoring of both polycythemia vera as well as diabetes mellitus. CONCLUSION This report brings to light unmasking of a new adverse effect of sodium-glucose co-transporter-2 inhibitors in clinical practice caused by volume loss, apart from hypotension and falls.

Abstract
Advanced lung disease is associated with gastroesophageal reflux disease (GERD). The thoracoabdominal pressure gradient (TAPG) facilitates gastroesophageal reflux, but the effects of TAPG on gastroesophageal reflux in patients with pulmonary disease have not been well defined. Patients diagnosed with end-stage lung disease are expected to have the most extreme derangement in respiratory mechanics. The aim of this study is to explore the relationship between TAPG and reflux in lung transplant (LTx) candidates. We reviewed LTx recipients who underwent pretransplant esophageal high-resolution manometry and a 24-hour pH study. Patients were excluded if they were undergoing redo LTx, had manometric hiatal hernia, or had previously undergone foregut surgery. TAPG was defined as the intra-abdominal pressure minus the intrathoracic pressure during inspiration. Adjusted TAPG was calculated by the TAPG minus the resting lower esophageal sphincter (LES) pressure (LESP). Twenty-two patients with normal esophageal function tests (i.e., normal esophageal motility with neither manometric hiatal hernia nor pathological reflux on 24-hour pH monitoring) were selected as the pulmonary disease-free control group. In total, 204 patients underwent LTx between January 2015 and December 2016. Of these, 77 patients met inclusion criteria. We compared patients with obstructive lung disease (OLD, n = 33; 42.9%) and those with restrictive lung disease (RLD, n = 42; 54.5%). 2/77 patients (2.6%) had pulmonary arterial hypertension. GERD was more common in the RLD group than in the OLD group (24.2% vs. 47.6%, P = 0.038). TAPG was similar between the OLD group and the controls (14.2 vs. 15.3 mmHg, P = 0.850); however, patients in the RLD group had significantly higher TAPG than the controls (24.4 vs. 15.3 mmHg, P = 0.002). Although TAPG was not correlated with GERD, the adjusted TAPG correlated with reflux in all 77 patients with end-stage lung disease (DeMeester score, rs = 0.256, P = 0.024; total reflux time, rs = 0.259, P = 0.023; total number of reflux episodes, rs = 0.268, P = 0.018). Additionally, pathological reflux was seen in 59.1% of lung transplant candidates with adjusted TAPG greater than 0 mmHg (i.e., TAPG exceeding LESP); GERD was seen in 30.9% of patients who had an adjusted TAPG ≤ 0 mmHg. In summary, TAPG varies based on the underlying cause of lung disease. Higher adjusted TAPG increases pathological reflux, even if patients have normal antireflux anatomy and physiology (i.e., no hiatal hernia and manometrically normal LES function). Adjusted TAPG may provide further insights into the pathophysiology of GERD.

Abstract
Chronic airway inflammation and infection drive morbidity and mortality among patients with cystic fibrosis (CF). While Haemophilus influenzae and Staphylococcus aureus predominate in children, the prevalence of Pseudomonas aeruginosa increases as patients age. Other bacteria, including species within the Burkholderia cepacia complex (Bcc), are also more prevalent among adults with CF. Species within the Bcc accelerate lung function decline and can trigger development of "cepacia syndrome," both before and after lung transplantation. As a result, some centers advise against lung transplantation for Bcc-infected patients; however, little is known about the relative virulence of uncommon Bcc species. We describe a successful lung re-transplant in a patient with CF, chronic Burkholderia ambifaria airway infection, and cepacia syndrome.

Abstract
Background The drug pirfenidone has been shown to slow the progression and decrease mortality of idiopathic pulmonary fibrosis (IPF). Its exact mechanism is unknown, but it likely inhibits pro-fibrotic cytokine transforming growth factor beta, a known contributor to wound healing. We evaluated whether patients taking pirfenidone until lung transplantation had increased risk of impaired wound healing post-transplant. This information could determine whether pirfenidone should be discontinued prior to listing to allow for a wash-out period. Methods We retrospectively reviewed patients who underwent lung transplantation for pulmonary fibrosis at Norton Thoracic Institute in Phoenix, Arizona, from January 2014 to December 2015. Results We describe 18 patients who took pirfenidone up to a month before transplant. Aside from one patient who experienced sternal dehiscence due to a surgical issue, all remaining patients did well with no evidence of airway dehiscence. Each of these 17 patients had been on pirfenidone for at least 30 days; nine patients had been on pirfenidone for over 90 days. Baseline characteristics including age, sex, body mass index, renal function, liver function, glucose level, pre-transplant corticosteroid use, and post-transplant immunosuppressant therapy were similar. Conclusions In our experience, pirfenidone may be safely continued until lung transplantation. Only one patient in our series experienced impaired wound healing related to a surgical issue, even when pirfenidone was continued until lung transplantation. We found no evidence of impaired wound healing or airway complications after lung transplantation in patients who were treated with pirfenidone before lung transplantation.

Abstract
Patients under consideration for lung transplantation as treatment for end-stage lung diseases such as idiopathic pulmonary fibrosis (IPF) often have risk factors such as a history of smoking or concomitant emphysema, both of which can predispose the patient to lung cancer. In fact, IPF itself increases the risk of lung cancer development by 6.8% to 20%. Solid organ malignancy (non-skin) is an established contraindication for lung transplantation. We encountered a clinical dilemma in a patient who presented with an IPF flare-up and underwent urgent evaluation for lung transplantation. After transplant, the patient's explanted lungs showed extensive adenocarcinoma in situ, with the foci of invasion and metastatic adenocarcinoma in N1-level lymph nodes, as well as usual interstitial pneumonia. Retrospectively, we saw no evidence to suggest malignancy in addition to the IPF flare-up. Clinical diagnostic dilemmas such as this emphasize the need for new noninvasive testing that would facilitate malignancy diagnosis in patients too sick to undergo invasive tissue biopsy for diagnosis. Careful pathological examination of explanted lungs in patients with IPF is critical, as it can majorly influence immunosuppressive regimens, surveillance imaging, and overall prognosis after lung transplant.

Abstract
Pneumatosis intestinalis (PI) is an uncommon medical condition in which gas pockets form in the walls of the gastrointestinal tract. The mechanism by which this occurs is poorly understood; however, it is often seen as a sign of serious bowel ischemia, which is a surgical emergency. Since the early days of solid organ transplantation, PI has been described in recipients of kidney, liver, heart, and lung transplant. Despite the dangerous connotations often associated with PI, case reports dating as far back as the 1970s show that PI can be benign in solid organ transplant recipients. This is an important observation, as operative intervention in these patients carries greater risk than surgical procedures in the general population. The higher operative risks in the transplant population are partly due to their immunosuppressed status and poor wound healing. Furthermore, no clear consensus exists on the optimal management of PI. Various treatment strategies such as bowel rest, antibiotics, and parenteral feeding have been implemented with similar levels of success. With the increasing use of solid organ transplantation, PI is being recognized with increasing frequency. In this review, we provide a summary of the incidence, presentation, diagnosis, and management of PI, particularly as it affects recipients of solid organ transplantation.

Abstract
OBJECTIVE To study the clinical profile and the management of patients with disorders of sex development (DSD). DESIGN AND SETTING Retrospective study from a tertiary care hospital of North India. METHODS AND PATIENTS One hundred ninety-four patients of DSD registered in the Endocrine clinic of Postgraduate Institute of Medical Education and Research, Chandigarh between 1995 and 2014 were included. RESULTS One hundred and two patients (52.5%) had 46,XY DSD and seventy-four patients (38.1%) had 46,XX DSD. Sex chromosome DSD was identified in seven (3.6%) patients. Of 102 patients with 46,XY DSD, 32 (31.4%) had androgen insensitivity syndrome and 26 (25.5%) had androgen biosynthetic defect. Of the 74 patients with 46,XX DSD, 52 (70.27%) had congenital adrenal hyperplasia (CAH) and eight (10.8%) had ovotesticular DSD. Five patients with sex chromosome DSD had mixed gonadal dysgenesis. Excluding CAH, majority of the patients (90%) presented in the post-pubertal period. One-fourth of the patients with simple virilising CAH were reared as males because of strong male gender identity and behaviour and firm insistence by the parents. Corrective surgeries were performed in twenty patients (20%) of 46,XY DSD without hormonal evaluation prior to the presentation. CONCLUSION Congenital adrenal hyperplasia is the most common DSD in the present series. Most common XY DSD is androgen insensitivity syndrome, while CAH is the most common XX DSD. Delayed diagnosis is a common feature, and corrective surgeries are performed without seeking a definite diagnosis.

Abstract
Background Preoperative atrial fibrillation is associated with poor outcomes after cardiac surgery, but its effect on lung transplantation outcomes remains unknown. Methods We retrospectively reviewed the charts of 235 patients who underwent lung transplantation in our institution from 2013 to 2015, analyzing demographics, length of stay, survival, readmissions, and cardiac events. Mean recipient age was 59 ± 11 years, and 142 (60.4%) were men. Patients were grouped according to pre-transplantation atrial fibrillation status (atrial fibrillation/no atrial fibrillation). Results The atrial fibrillation group ( n = 38; 16.2%) was significantly older with a longer ischemic time, more postoperative atrial arrhythmias (73.7% vs. 20.8%, p = 0.01), and a longer median postoperative length of stay (16 vs. 13 days, p = 0.02). The median total hospital stay in the first postoperative year was also higher in the atrial fibrillation group (27 vs. 21 days, p = 0.25). Short-term survival and survival during follow-up did not differ significantly between groups. Conclusions Lung transplant recipients with preoperative atrial fibrillation are at increased risk of adverse cardiovascular outcomes and longer hospital stay. Preoperative atrial fibrillation may portend adverse events after lung transplantation.

Abstract
CASE PRESENTAION A 58-year-old man presented with a 6-month history of profound fatigue and a weight loss of 35 to 40 pounds. He reported occasional night sweats and mildly painful knees and elbows without swelling or redness. He denied respiratory symptoms, rashes, or fevers. He had no respiratory symptoms. The patient's history was significant for rheumatoid arthritis (with arthralgias and joint involvement), paroxysmal atrial fibrillation, and hypothyroidism. His medications included digoxin and metoprolol. He had been taking methotrexate and low-dose prednisone (5 mg) for approximately 10 years but discontinued taking these medications 2 years prior to current presentation. Originally from West Virginia, the patient had relocated to Arizona during the early 1980s. There was no history of international travel or TB. He had no exposure history to birds, bird feathers, or mold; however, he did report exposure to dust at his current job as a home building superintendent. He reported a 10 pack-year history of smoking, having quit 20 years ago. His family history was significant for renal sarcoidosis in his mother.

Abstract
p40, one of the two isomers of p63, is nowadays widely used for diagnosis of squamous cell carcinoma, especially in subtyping non-small cell carcinoma on lung biopsies. We describe a case in which lung tumour was misdiagnosed as squamous cell carcinoma due to p40 immunopositivity. A 36-year-old lady presented with cough and left sided chest pain of 2 months duration. Chest imaging revealed a lesion in left lower lobe of the lung and biopsy was suggestive of squamous cell carcinoma. However, past history revealed amputation of great toe for non-healing discharging ulcer which on histopathology was diagnosed as choriocarcinoma. She also had a history of hysterectomy five years ago, details of which were not available. Post-amputation β-hCG levels were high and she had been treated with multimodality chemotherapy for choriocarcinoma. She had good response to chemotherapy initially, however became resistant later on. Review of the lung biopsy in the light of the past history along with extensive literature review led to the final diagnosis of metastatic trophoblastic tumour to lung. Hence, awareness that p40 immunopositivity can be seen in trophoblastic tumours is essential to avoid misdiagnosis, especially in sites like the lung where squamous cell carcinoma is common.

Extracorporeal membrane oxygenation as a bridge to lung transplantation: A single-center experience in the present era. J Thorac Cardiovasc Surg 2017; 154:1798-1809. [PMID: 29042051 DOI: 10.1016/j.jtcvs.2017.06.063] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2016] [Revised: 04/03/2017] [Accepted: 06/27/2017] [Indexed: 12/12/2022]
Abstract
OBJECTIVE Extracorporeal membrane oxygenation has been used as a bridge to lung transplantation in patients with rapid pulmonary function deterioration. The reported success of this modality and perioperative and functional outcomes are varied. METHODS We retrospectively reviewed all patients who underwent lung transplantation at our institution over 1 year (January 1, 2015, to December 31, 2015). Patients were divided into 2 groups depending on whether they required extracorporeal membrane oxygenation support as a bridge to transplant; preoperative characteristics, lung transplantation outcomes, and survival were compared between groups. RESULTS Of the 93 patients, 12 (13%) received bridge to transplant, and 81 (87%) did not. Patients receiving bridge to transplant were younger, had higher lung allocation scores, had lower functional status, and were more often on mechanical ventilation at listing. Most patients who received bridge to transplant (n = 10, 83.3%) had pulmonary fibrosis. Mean pretransplant extracorporeal membrane oxygenation support was 103.6 hours in duration (range, 16-395 hours). All patients who received bridge to transplant were decannulated immediately after lung transplantation but were more likely to return to the operating room for secondary chest closure or rethoracotomy. Grade 3 primary graft dysfunction within 72 hours was similar between groups. Lung transplantation success and hospital discharge were 100% in the bridge to transplant group; however, these patients experienced longer hospital stays and higher rates of discharge to acute rehabilitation. The 1-year survival was 100% in the bridge to transplant group and 91% in the non-bridge to transplant group (log-rank, P = .24). The 1-year functional status was excellent in both groups. CONCLUSIONS Extracorporeal membrane oxygenation can be used to safely bridge high-acuity patients with end-stage lung disease to lung transplantation with good 30-day, 90-day, and 1-year survival and excellent 1-year functional status. Long-term outcomes are being studied.
