Long-term follow-up of conservative treatment of Charcot feet

Abstract Background Charcot arthropathy (CN) can ultimately lead to limb loss despite appropriate treatment. Initial conservative treatment is the accepted treatment in case of a plantigrade foot. The aim of this retrospective study was to investigate the mid- to long-term clinical course of CN initially being treated conservatively, and to identify risk factors for reactivation and contralateral development of CN as well as common complications in CN. Methods A total of 184 Charcot feet in 159 patients (median age 60.0 (interquartile range (IQR) 15.5) years, 49 (30.1%) women) were retrospectively analyzed by patient chart review. Rates of limb salvage, reactivation, contralateral development and common complications were recorded. Statistical analysis was performed to identify possible risk factors for limb loss, CN reactivation, contralateral CN development, and ulcer development. Results Major amputation-free survival could be achieved in 92.9% feet after a median follow-up of 5.2 (IQR 4.25, range 2.2–11.25) years. CN recurrence occurred in 13.6%. 32.1% had bilateral CN involvement. Ulcers were present in 72.3%. 88.1% patients were ambulating in orthopaedic footwear without any further aids. Presence of Diabetes mellitus was associated with reactivation of CN, major amputation and ulcer recurrence. Smoking was associated with ulcer development and necessity of amputations. Conclusions With consistent conservative treatment of CN with orthopaedic footwear or orthoses, limb preservation can be achieved in 92.9% after a median follow-up of 5.2 years. Patients with diabetic CN are at an increased risk of developing complications and CN reactivation. To prevent ulcers and amputations, every effort should be made to make patients stop smoking.

AbstractThe incidence and risk factors associated with radiation-induced leukoencephalopathy (RIL) in long-term survivors of high-grade glioma (HGG) are still poorly investigated. We performed a retrospective research in our institutional database for patients with supratentorial HGG treated with focal radiotherapy, having a progression-free overall survival > 30 months and available germline DNA. We reviewed MRI scans for signs of leukoencephalopathy on T2/FLAIR sequences, and medical records for information on cerebrovascular risk factors and neurological symptoms. We investigated a panel of candidate single nucleotide polymorphisms (SNPs) to assess genetic risk. Eighty-one HGG patients (18 grade IV and 63 grade III, 50M/31F) were included in the study. The median age at the time of radiotherapy was 48 years old (range 18–69). The median follow-up after the completion of radiotherapy was 79 months. A total of 44 patients (44/81, 54.3%) developed RIL during follow-up. Twenty-nine of the 44 patients developed consistent symptoms such as subcortical dementia (n = 28), gait disturbances (n = 12), and urinary incontinence (n = 9). The cumulative incidence of RIL was 21% at 12 months, 42% at 36 months, and 48% at 60 months. Age > 60 years, smoking, and the germline SNP rs2120825 (PPARg locus) were associated with an increased risk of RIL. Our study identified potential risk factors for the development of RIL (age, smoking, and the germline SNP rs2120825) and established the rationale for testing PPARg agonists in the prevention and management of late-delayed radiation-induced neurotoxicity.

A number of studies demonstrate that patients with traditional risk factors (TRF) have not only increases primary risk of atherothrombotic events, but are also associated with many complicates and poor prognosis.Purpose: assessment of TRF effect on the incidence of complications and outcomes in patients with acute coronary syndrome (ACS).Materials and methods: in 255 patients hospitalized with ACS were retrospective determined the TRF prevalence, frequency of the complications and correlation between the presence of TRF and the risk of complications and long-term prognosis (follow-up 1 year).Results: patients had TRF very often, 80% patients had more than 3 TRFs. The presence of some TRFs (smoking, abdominal obesity, family history) was associated with a significantly increased risk of complications in patients with ACS, including life-threatening. Effect of TRF on long-term prognosis was not determined.Conclusion: the findings suggest the need to evaluation TRF not only in primary preventive and also to improve the effectiveness of risk stratification in patients with ACS.

Abstract Background: The global incidence of thyroid cancer (TC) has risen considerably during the last three decades, while prognosis is generally favorable. We assessed the long-term all-cause mortality in TC survivors compared to the general population, and its association with cardiovascular risk factors. Methods: Individuals diagnosed with TC during 2001-2014 (TC group) and age- and sex-matched individuals from the same Israeli healthcare system without thyroid disease or a cancer history (non-TC group) were compared. Cox regression hazard ratios (HRs) and 95% confidence intervals (95%CIs) for all-cause mortality were calculated by exposure status. Results: During a 15-year follow-up (median 8 years), 577 TC survivors out of 5,677 (10.2%) TC patients and 1,235 individuals out of 23,962 (5.2%) non-TC patients died. The TC survivors had an increased risk of all-cause mortality (HR=1.89, 95%CI 1.71-2.10), after adjusting for cardiovascular risk factors already present at follow-up initiation. This increased risk was most pronounced in the 55- to 64-year-old age group (HR=1.49, 95%CI 1.33-1.67). The TC survivors who died by study closure had more hypertension (14.6% vs. 10.3%, P = 0.002), more dyslipidemia (11.4% vs. 7.2%, P < 0.001), and more cardiovascular disease (33.6% vs. 22.3%, P = 0.05) compared to those who died in the non-TC group. Conclusions: This large cohort study showed higher all-cause mortality with a higher prevalence of hypertension, dyslipidemia, and cardiovascular disease among TC survivors compared to matched non-TC individuals. Primary and secondary prevention of cardiovascular risk factors in TC survivors is mandatory.

Background Osteoarthritis (OA) of the glenohumeral joint results in significant pain and functional limitations. It is unclear which risk factors increase the risk of developing glenohumeral OA amongst Rotator Cuff Repair (RCR) patients. The purpose of this systematic review was to examine the risk factors which may contribute to the development of osteoarthritic changes post-operatively. Methods MEDLINE, Embase, and PubMed databases were searched to identify studies reporting on demographics of patients who develop OA following RCR. Results Seventeen articles were identified investigating a total of 1292 patients. The overall quality of evidence was low. Pooled assessment of OA incidence following RCR at minimum 5 years follow-up found 26% of patients developed OA. Patients requiring revision surgery following retears developed OA at a rate of 29%. Surgical technique and patient demographics may also contribute to degenerative changes. Discussion This review found correlations between the aforementioned risk factors and glenohumeral joint degeneration at long-term follow-up after RCR. These findings suggest that future long-term studies should aim to identify prognostic factors that may place a patient at increased risk of developing OA. Such data can be used to counsel patients with respect to long-term outcomes following surgical intervention.

Untethering Surgery

OBJECTIVE Lipoma of the conus medullaris (LCM) causes neurological symptoms known as tethered cord syndrome (TCS). The symptoms can be seen at diagnosis and during long-term follow-up. In this report, pediatric patients with LCMs who underwent untethering surgery, under the policy of performing surgery if diagnosed regardless of symptoms, were retrospectively reviewed to evaluate long-term surgical outcomes. Possible risk factors for retethered cord syndrome (ReTCS) were evaluated in the long-term follow-up period. METHODS A total of 51 consecutive pediatric patients with LCMs who underwent a first untethering surgery and were followed for > 100 months were retrospectively analyzed. The surgery was performed with the partial removal technique. Pre- and postoperative clinical and radiological data were reviewed to analyze the outcomes of surgery and identify potential risk factors for ReTCS. RESULTS During follow-up, 12 patients experienced neurological deterioration due to ReTCS. The overall 10-year and 15-year progression-free survival rates were 82.3% and 75.1%, respectively. On univariate analysis, a lipoma type of lipomyelomeningocele (OR 11, 95% CI 2.50–48.4; p = 0.0014), patient age at the time of surgery (OR 0.41, 95% CI 0.14–1.18; p = 0.0070), and the mean patient growth rate after surgery (OR 2.00, 95% CI 1.12–3.41; p = 0.0040) were significant factors associated with ReTCS. Cox proportional hazard models showed that a lipoma type of lipomyelomeningocele (HR 5.16, 95% CI 1.54–20.1; p = 0.010) and the mean growth rate after surgery (HR 1.88, 95% CI 1.00–3.50; p = 0.040) were significantly associated with the occurrence of ReTCS. CONCLUSIONS More complex lesions and a high patient growth rate after surgery seemed to indicate increased risk of ReTCS. Larger prospective studies and registries are needed to define the risks of ReTCS more adequately.

Background. Seizures is a very common clinical presentation of cerebral venous thrombosis (CVT); however, little is known about the future risk of epilepsy in patients suffering CVT. Our objective was to analyze risk factors for epilepsy in a long-term follow-up after CVT. Methods. This is a cohort descriptive study of consecutive non-selected patients with acute cerebrovascular disease, systematically registered from 1986 to 2010 in a third-level referral center of Mexico City. Here we analyzed 340 patients who survived the first 6 months after CVT, who were not epileptic at baseline and for whom complete long-term information on neurological outcome was available. Results. Seizures occurred in 183 (54%) patients, in 26% of them as a clinical presentation and 74% at some point during follow-up. Focal motor seizures occurred in 6.5%, secondary generalized focal seizures in 13.8% and generalized tonic-clonic seizures in 22.4%. Status epilepticus occurred in 13 (7%) cases. In all, during a median follow-up of 28 months (range 2 to 288 months), epilepsy was present in 14.7% (27.3% of those who presented seizures). In a multivariate analysis adjusted for multiple confounders, risk factors associated with an increased risk of epilepsy during follow-up were presenting seizures as a clinical presentation [odds ratio (OR): 4.32, 95% confidence interval (CI): 2.20-8.48], pregnancy and puerperium (OR: 2.03, 95% CI: 1.11-3.71) and thrombosis of the longitudinal sinus (OR: 1.86, 95% CI: 1.01-3.41). Conclusion. Seizures are common at CVT presentation, but risk increases during the acute phase after thrombotic event. Most seizures resolve during the first month, but epilepsy occurred in 15% of patients with CVT in the long run.

Abstract Exposure to pre-transplant nephrotoxic agents, total body irradiation (TBI), and presence of chronic graft-versus-host disease (cGVHD) have been identified as risk factors for developing CKD after HCT. However, small sample size, short follow-up post-HCT, and varying definitions of CKD have precluded a precise estimation of the magnitude of risk and associated risk factors. The aim of the current study was to describe the incidence and risk factors associated with the development of delayed CKD in HCT survivors. Eligible subjects underwent HCT for hematological malignancies or severe aplastic anemia at City of Hope, survived at least one year post-transplant, and were free of CKD at one year post-HCT. Information on pre-transplant therapeutic exposures and post-transplant CKD was obtained via medical record abstraction. All CKD cases were defined according to the National Kidney Foundation’s definition based on glomerular filtration rate (GFR) values. The endogenous filtration marker creatinine was used to estimate GFR values. CKD was defined as a sustained elevation of serum creatinine which infer a GFR of less than 60 mL/min/1.73 m2 for 3 months or longer. The equation used to calculate GFR was as follows: GFR = 186 x (Pcr) −1.154 x (age) − 0.203 (x 0.742 if female) (x 1.210 if African American). Totally, 1,546 eligible subjects were identified (median age at HCT of 34.4, median length of follow-up 6.2 years; autologous HCT in 718 patients [46%], related donor HCT in 726 patients [47%], and unrelated donor HCT in 102 patients [7%]; 59% of subjects (n=913) were male). A total of 65 patients were identified with CKD, resulting in a cumulative incidence of 3.6% [95% confidence interval (CI), 2.6% to 4.6%] at five years post–HCT and 4.8% at 10 years (autologous HCT: 2.9% at five years; matched sibling HCT: 4.1%; matched unrelated donor HCT: 10.5%, p<0.05). In allogeneic transplant recipients, older age at HCT (RR per increase of five years, 1.34; 95% CI, 1.30 to 1.38), prophylaxis/treatment of GvHD with cyclosporine and/or tacrolimus (RR, 4.32; 95% CI, 1.25 to 14.89), and a primary diagnosis of Multiple Myeloma (RR=5.38, 95% CI=1.79 to 16.15) were associated with increased risk. For autologous transplant recipients, older age at HCT was associated with increased risk (RR per increase of five years, 1.33; 95% CI, 1.29 to 1.38). Of note, use of TBI, and chemotherapeutic agents for conditioning, and a history of fungal infection were not associated with risk of delayed CKD development. This study describes the magnitude of risk of delayed chronic kidney disease in a large cohort of long-term survivors of autologous and allogeneic HCT, as well as identifies high risk groups in this population, thus setting the stage for appropriate long-term follow-up of the vulnerable sub–groups.

Neonatal Renal Vein Thrombosis

BackgroundThere are limited data at a population level on the burden, risk factors, and long-term outcomes of neonatal renal vein thrombosis (nRVT). We conducted a population-based cohort study to understand the epidemiology and outcomes of nRVT over a 25-year period in Ontario.MethodsUsing linked administrative health databases, all hospitalized neonates ≤28 days born in Ontario between 1992 and 2016 with nRVT were identified. The primary outcome was to calculate the incidence of nRVT and trend over time in Ontario. We also determined the risk factors associated with nRVT as well as the risk of long-term outcomes after nRVT, including CKD, ESKD, all-cause mortality, and hypertension (HTN) compared with the healthy neonatal population without nRVT.ResultsThe annual incidence rate of nRVT was 2.6 per 100,000 live births (n=85). Presence of respiratory distress syndrome (OR, 8.01; 95% CI, 4.90 to 13.1), congenital heart disease (OR, 9.1; 95% CI, 5.05 to 16.4), central venous catheterization (OR, 3.9; 95% CI, 1.89 to 7.93), maternal preeclampsia (OR, 2.8; 95% CI, 1.6 to 4.79), and maternal diabetes (OR, 2.36; 95% CI, 1.36 to 4.07) conferred the highest risk for nRVT. Over a median follow-up of 15 years and after adjusting for confounders, neonates with nRVT versus the comparator cohort had a 15.5-fold risk of CKD, HTN, or death (n=49 [58%] versus n=90,050 [3%]; 95% CI, 11.7 to 20.6); 12.3-fold increased risk of CKD or death (n=39 [46%] versus n=32,016 [1%]; 95% CI, 8.9 to 16.8); and a 15.7-fold increased risk of HTN (n=33 [39%] versus n=64,458 [2%]; 95% CI, 11.1 to 21.1). None of the nRVT cohort developed ESKD. The median time to composite outcome of CKD, HTN, or death was 11.1 years.ConclusionsPatients with a history of nRVT remain at higher risk than the general population for long-term morbidity or mortality, indicating the need for long-term follow-up.
