Project description:Craniofacial surgery as a subspecialty has finally taken off in India. Young plastic surgeons in the early 1990s became fascinated by its enormous scope. The author was also among the lucky ones to be trained in this field with Dr. Ian Jackson at the Craniofacial Center at Southfield, Michigan, from 1993-1994. This facility for craniofacial surgery was established in the North Indian tertiary care hospital at the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, in 1995. Methods:We have reviewed the outcomes of management of craniosynostosis patients and evaluated changes in these outcomes as the experience was gained. The study is a retrospective chart review of the 169 patients operated on for various craniosyntoses in the hospital, for the last 25 years from January 1995 to July 2019. Results:The whole spectrum of craniosynostoses patients have been operated on and followed up for up to 20 years. All the patients underwent open surgery involving fronto-orbital advancement and remodelling of the deformed calvarium. It was noted that all the syndromic patients required more than one operation, whereas the non-syndromic patients had a stable result after a single surgery. Craniofacial surgery has now truly arrived in India. Our experience with management of craniosynostosis at PGIMER, Chandigarh, has shown an acceptable morbidity and mortality which is at par with the global standards.

Project description:We aim to describe the incidence and source of contagion of COVID-19 in patients with IBD, as well as the risk factors for a severe course and long-term sequelae. This is a prospective observational study of IBD and COVID-19 included in the ENEIDA registry (53,682 from 73 centres) between March-July 2020 followed-up for 12 months. Results were compared with data of the general population (National Centre of Epidemiology and Catalonia). A total of 482 patients with COVID-19 were identified. Twenty-eight percent were infected in the work environment, and 48% were infected by intrafamilial transmission, despite having good adherence to lockdown. Thirty-five percent required hospitalization, 7.9% had severe COVID-19 and 3.7% died. Similar data were reported in the general population (hospitalisation 19.5%, ICU 2.1% and mortality 4.6%). Factors related to death and severe COVID-19 were being aged ≥ 60 years (OR 7.1, 95% CI: 1.8-27 and 4.5, 95% CI: 1.3-15.9), while having ≥2 comorbidities increased mortality (OR 3.9, 95% CI: 1.3-11.6). None of the drugs for IBD were related to severe COVID-19. Immunosuppression was definitively stopped in 1% of patients at 12 months. The prognosis of COVID-19 in IBD, even in immunosuppressed patients, is similar to that in the general population. Thus, there is no need for more strict protection measures in IBD.

Project description:IntroductionData on the evolution of gastric precancerous lesions (GPL), especially in countries of a Low gastric cancer incidence area are limited. Our objective was to study a long-term evolution of GPL in France.MethodsAll the patients diagnosed with GPL (atrophic gastritis, intestinal metaplasia [IM], and dysplasia) between 2000 and 2015 and fulfilling criteria for evolution assessment (at least 2 endoscopies, minimal follow-up of 6 months, and at least 2 biopsies obtained from the antrum and corpus) were included. Clinical and endoscopic data were analyzed, and histological samples were reviewed by an expert pathologist with evaluation of the Operative Link on Gastric Intestinal Metaplasia Assessment stage and type of IM.ResultsFrom the 507 patients with GPL, 79 fulfilled the strict criteria. During a mean follow-up of 66 months, during which the patients had a mean number of 4 endoscopies (min-max: 2-21) with 9 biopsies/endoscopy, a stability was observed in 70% of patients. Progression occurred in 14% of patients, within a mean delay of 62.1 months (min-max: 17-99). Progression of the lesions was significantly higher in patients with incomplete type of IM (relative risk of progression for incomplete IM: 11.5; 95% confidence interval 2.5-53.1). Regression of IM occurred in 16% of the patients, after a mean delay of 90 months.DiscussionThis study shows that the patients with antrum-limited IM, especially of incomplete type, are at the highest risk of developing gastric cancer. In most patients, however, the lesions remain stable, which highlights the need for additional markers to better target the patients at risk of progression.

Project description:ObjectivesTo report the long-term follow-up data including computed tomography (CT) findings of oxaliplatin-induced liver damage in patients with colorectal cancer.MethodsThree hundred and fifty-six patients who underwent surgery followed by oxaliplatin-based chemotherapy (OBC) for colorectal cancer between January 2013 and December 2014 were included. Abdominal CT images and laboratory results (serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, total bilirubin, and platelet counts) were reviewed immediately before (as baseline), during, and after adjuvant OBC. Abdominal CT images were reviewed to assess the heterogeneous liver parenchyma, increase in size of the spleen, development of acute portosystemic shunts during OBC, and imaging findings of chronic portal hypertension.ResultsDuring OBC, 90.2% (321/356) of the patients developed parenchymal heterogeneity. Increase in the spleen size during the OBC period was seen in 62.4% (225/356) of patients. The overall rate of development of acute portosystemic shunts during OBC was 23.9% (85/356). These findings were resolved after cessation of OBC except in 1.4% (5/356) of the patients in whom chronic portal hypertension persisted even after completion of OBC. Serum AST, ALT, and total bilirubin levels increased and platelet counts decreased during OBC and returned to normal after completion of OBC; however, they did not reach the pre-OBC levels.ConclusionAlthough most changes associated with liver damage reversed to normal range after completion of OBC, some parameters did not reverse to the pretreatment level, and chronic portal hypertension developed in a small number of patients.Advances in knowledgeChronic, persistent oxaliplatin-induced liver damage was not an infrequent complication after oxaliplatin-based chemotherapy for patients with colorectal cancer. It may cause non-cirrhotic portal hypertension and associated complications such as variceal bleeding.

Project description:BackgroundScreening flexible sigmoidoscopy reduces incidence and mortality of colorectal cancer. Previously reported results from the Prostate, Lung, Colorectal, and Ovarian Cancer (PLCO) screening trial had a median follow-up of 12 years. Whether the benefit is sustained over the long term and remains so in both sexes and all age groups is uncertain. We report long-term results after an additional 5 years of follow-up.MethodsParticipants in the PLCO trial were recruited from the general population in the catchment areas of ten screening centres across the USA, without previous diagnosis of a prostate, lung, colorectal, or ovarian cancer or current cancer treatment. From 1993 to 2001, participants aged 55-74 years were randomly assigned to usual care or flexible sigmoidoscopy at baseline and again at 3 years or 5 years. Randomisation was done within blocks and stratified by centre, age, and sex. The primary endpoint was cause-specific mortality and secondary endpoints included incidence and tumour staging; cause of death was determined without knowledge of study arm. In this analysis, we assessed incidence and mortality rates overall, by time-period, and by combinations of sex, age at baseline (55-64 years/65-74 years), location (distal/proximal), and stage, on an intent-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT00002540.FindingsAfter a median follow-up of 15·8 years (IQR 13·2-18·0) for incidence and 16·8 years (14·4-18·9) for mortality, the incidence of colorectal cancer was significantly lower in the intervention arm (1461 cases; 12·55 per 10 000 person-years) than with usual care (1761 cases; 15·33 per 10 000 person-years; relative risk [RR] 0·82, 95% CI 0·76-0·88). Similarly, mortality was lower in the intervention arm (417 deaths; 3·37 per 10 000 person-years) than the usual care arm (549; 4·48 per 10 000 person-years; RR 0·75, 95% CI 0·66-0·85). The reduction in mortality was limited to the distal colon, with no significant effect in the proximal colon. Reductions in incidence were significantly larger in men than women (pinteraction=0·04) and reductions in mortality were significantly larger in the older age group (65-74 years vs 55-64 years at baseline; pinteraction=0·01).InterpretationReductions in colorectal cancer incidence and mortality from flexible sigmoidoscopy screening are sustained over the long term. Differences by sex and age should be examined in other ongoing trials of colorectal cancer screening to help clarify if different screening strategies would achieve greater risk reduction.FundingExtended follow-up was funded under NIH contract HHSN261201600007I.

Project description:ContextDespite tremendous interest in hypoparathyroidism, large cohort studies describing typical treatment patterns, laboratory parameters, and rates of complications are lacking.ObjectiveOur objective was to characterize the course of disease in a large cohort of hypoparathyroid patients.Design and settingWe conducted a chart review of patients with permanent hypoparathyroidism identified via a clinical patient data registry. Patients were seen at a Boston tertiary-care hospital system between 1988 and 2009.PatientsWe identified 120 patients. Diagnosis was confirmed by documented hypocalcemia with a simultaneous low or inappropriately normal PTH level for at least 1 yr. Mean age at the end of the observation period was 52 ± 19 (range 2-87) yr, and the cohort was 73% female.Main outcome measureWe evaluated serum and urine laboratory results and renal and brain imaging.ResultsWe calculated time-weighted average serum calcium measurements for all patients. The time-weighted average for calcium was between 7.5 and 9.5 mg/dl for the majority (88%) of patients. Using linear interpolation, we estimated the proportion of time within the target calcium range for each patient with a median of 86% (interquartile range 67-98%). Of those with a 24-h urine collection for calcium (n = 53), 38% had at least one measurement over 300 mg/d. Of those with renal imaging (n = 54), 31% had renal calcifications, and 52% of those with head imaging (n = 31) had basal ganglia calcifications. Rates of chronic kidney disease stage 3 or higher were 2- to 17-fold greater than age-appropriate norms.ConclusionsHypoparathyroidism and its treatment carry a large burden of disease. Renal abnormalities are particularly common.

Project description:PURPOSE: To assess the long-term follow-up results of laparoscopic pyeloplasty for ureteropelvic junction obstruction. MATERIALS AND METHODS: Sixty-five patients (mean age, 43.8 years) who underwent standard laparoscopic pyeloplasty by transperitoneal approaches were enrolled in this study. The chief complaint was flank pain (n=57 patients); the remaining cases were detected incidentally. Twenty-three patients had undergone previous abdominal surgeries, including open pyeloplasty and endopyelotomy. Mean stricture length was 1.06 cm. Grade 3/4 and 4/4 hydronephrosis was detected in 36 and 14 patients, respectively. An obstructive pattern was present on the renal scan in 53 patients (81.5%). RESULTS: Fifty-seven patients were treated with dismembered Anderson-Hynes pyeloplasty and eight patients with Fenger pyeloplasty. During the operation, crossing vessels were found in 27 patients (41.5%). Mean operating time was 159.42 minutes. Although there were no cases of open conversion, two patients with colon and spleen injuries were detected postoperatively. The mean starting time of postoperative ambulation and diet was 1.54 days and 1.86 days, respectively. Mean hospital stay was 8.09 days. Mean follow-up period was 36.5 months. Follow-up intravenous pyelography and renal scan showed improvements in 59 patients, and the radiologic success rate was 90.8%. Eight patients showed failure on radiologic or symptomatic evaluation, and the overall success rate was 87.7%. In the comparative analysis between the success and failure groups, drained amount was the only risk factor related to failure (554.41 mL. vs. 947.70 mL, p=0.024). CONCLUSIONS: Long-term follow-up results support laparoscopic pyeloplasty as the standard treatment for ureteropelvic junction obstruction. Drained amount is a risk factor for failure of the operation.

Project description:BackgroundPrognostic factors are lacking in cardiac sarcoidosis (CS), and the effects of immunosuppressive treatments are unclear.ObjectivesTo identify prognostic factors and to assess the effects of immunosuppressive drugs on relapse risk in patients presenting with CS.MethodsFrom a cohort of 157 patients with CS with a median follow-up of 7 years, we analysed all cardiac and extra-cardiac data and treatments, and assessed relapse-free and overall survival.ResultsThe 10-year survival rate was 90% (95% CI, 84-96). Baseline factors associated with mortality were the presence of high degree atrioventricular block (HR, 5.56, 95% CI 1.7-18.2, p = 0.005), left ventricular ejection fraction below 40% (HR, 4.88, 95% CI 1.26-18.9, p = 0.022), hypertension (HR, 4.79, 95% CI 1.06-21.7, p = 0.042), abnormal pulmonary function test (HR, 3.27, 95% CI 1.07-10.0, p = 0.038), areas of late gadolinium enhancement on cardiac magnetic resonance (HR, 2.26, 95% CI 0.25-20.4, p = 0.003), and older age (HR per 10 years 1.69, 95% CI 1.13-2.52, p = 0.01). The 10-year relapse-free survival rate for cardiac relapses was 53% (95% CI, 44-63). Baseline factors that were independently associated with cardiac relapse were kidney involvement (HR, 3.35, 95% CI 1.39-8.07, p = 0.007), wall motion abnormalities (HR, 2.30, 95% CI 1.22-4.32, p = 0.010), and left heart failure (HR 2.23, 95% CI 1.12-4.45, p = 0.023). After adjustment for cardiac involvement severity, treatment with intravenous cyclophosphamide was associated with a lower risk of cardiac relapse (HR 0.16, 95% CI 0.033-0.78, p = 0.024).ConclusionsOur study identifies putative factors affecting morbidity and mortality in cardiac sarcoidosis patients. Intravenous cyclophosphamide is associated with lower relapse rates.

Project description:BackgroundTo address the lack of knowledge regarding the long-term risk of intracranial hemorrhage (ICH) after acute myocardial infarction (AMI), the aims of this study were to: (1) investigate the incidence, time trends, and predictors of ICH in a large population within 1 year of discharge after AMI; (2) investigate the comparative 1-year risk of ICH in AMI patients and a reference group; and (3) study the impact of previous ischemic stroke on ICH risk in patients treated with various antithrombotic therapies.Methods and resultsData about patients whose first AMI occurred between 1998 and 2010 were collected from the Swedish Register of Information and Knowledge about Swedish Heart-Intensive-Care Admissions (RIKS-HIA). Patients with an ICH after discharge were identified in the National Patient Register. Risk was compared against a matched reference population. Of 187 386 patients, 590 had an ICH within 1 year. The 1-year cumulative incidence (0.35%) was approximately twice that of the reference group, and it did not change significantly over time. Advanced age, previous ischemic or hemorrhagic stroke, and reduced glomerular filtration rate were associated with increased ICH risk, whereas female sex was associated with a decreased risk. Previous ischemic stroke did not increase risk of ICH associated with single or dual antiplatelet therapy, but increased risk with anticoagulant therapy.ConclusionThe 1-year incidence of ICH after AMI remained stable, at ?0.35%, over the study period. Advanced age, decreased renal function, and previous ischemic or hemorrhagic stroke are predictive of increased ICH risk.

Project description:BackgroundUntil recently acute inflammatory peri-myocardial syndromes have been associated with global rather regional left ventricular (LV) dysfunction. Recent advances in cardiac imaging with echocardiographic techniques and magnetic resonance imaging (MRI) permit comprehensive evaluation of global and regional LV function. Our study was aimed to assess regional LV function in 100 patients with acute perimyocarditis, and correlate these findings with the clinical presentation.MethodsWe report on 100 patients with acute perimyocarditis admitted during 2008-2011, in whom LV function was assessed by semi-quantitative wall motion score analysis on conventional echo. Long-term mortality and recurrent hospitalization were also assessed.ResultsWall motion score in 100 patients with acute perimyocarditis demonstrated a significant predominance of regional wall motion abnormalities in the infero-postero-lateral LV wall. These data correspond well with speckle tracking results of a subgroup of these patients published earlier. Recent MRI data show frequent late enhancement of contrast in the infero-lateral region of the LV in patients with perimyocarditis. These observations were useful in re-classification of our patients into one of the following groups: pure or predominant pericarditis, and pure or predominant myocarditis. Over a mean period of 37 months, there was no mortality. Though recurrent hospitalizations were rather frequent, no significant differences were observed among groups.ConclusionsRegional wall motion abnormalities in the infero-postero-lateral segments of the LV are frequent in patients with acute perimyocarditis. Detailed echocardiographic examination early in the course of the disease should become a major factor in the clinical differentiation among the various clinical presentations of acute inflammatory peri-myocardial syndromes. The long-term outcome of these patients appears to be benign, though recurrent hospitalizations are not infrequent.
