ABSTRACT

OBJECTIVES: Balanitis xerotica obliterans (BXO) is a chronic inflammatory disease with a little known incidence in pediatric population. The objective of this work was to describe our experience in the treatment of BXO. MATERIALS AND METHODS: Retrospective study carried out in 419 patients undergoing circumcision surgery between January 2014 and January 2017. Demographic, clinical, therapeutic, and anatomical and pathological variables, as well as complications during follow-up, were analyzed. RESULTS: Of the 419 patients, 41 (9.78%) were diagnosed with BXO. 6 patients were excluded owing to lack of follow-up, so 35 patients were analyzed. Mean age at diagnosis was 8.6 years. Suspicion diagnosis was clinical at physical exploration in 17 patients (48.6%), and at surgery in 18 patients (51.4%). Anatomical and pathological confirmation was performed in a total 35 patients (100%). During follow-up, 6 patients (17.14%) had lesions in the glans, 3 (8.57%) in the urethra, and 9 (25.71%) in both. 6 meatotomies (17.14%) and 5 new circumcisions (14.28%) had to be carried out. Mean recurrence time was 32.43 months. In 19 patients (54.28%), topical corticoids - ointment - were applied, and 1 patient (2.85%) received topical immunosuppressants. CONCLUSIONS: A close follow-up of patients with clinical or anatomical and pathological diagnosis of BXO is required given its high morbidity. The complications described in pediatric population include meatal and urethral stenosis, as well as recurrent phimosis, unless a sufficient amount of foreskin is resected.

El objetivo de este trabajo es describir nuestra experiencia en el tratamiento de las BXO. MATERIAL Y METODOS: Estudio retrospectivo de 419 pacientes intervenidos de circuncisión en el periodo comprendido entre enero de 2014 y enero de 2017. Analizamos variables demográficas, clínicas, anatomopatológicas, terapéuticas y complicaciones durante el seguimiento. RESULTADOS: De los 419 pacientes, 41 fueron diagnosticados de BXO (9,78%). Seis pacientes fueron excluidos por falta de seguimiento, por lo que se analizaron 35 pacientes. La media de edad al diagnóstico fue de 8,6 años. El diagnóstico de sospecha fue clínico durante la exploración física en 17 pacientes (48,6%) y durante la intervención en 18 (51,4%), realizando la confirmación anatomopatológica en un total de 35 pacientes (100%). Durante el seguimiento 6 pacientes (17,14%) presentaron lesiones en glande, 3 (8,57%) en uretra y 9 (25,71%) en ambas localizaciones, siendo necesaria la realización de 6 meatotomías (17,14%) y de nueva circuncisión en 5 (14,28%). El tiempo medio de recidiva fue de 32,43 meses. En 19 pacientes (54,28%) se aplicaron corticoides tópicos en pomada y en 1 paciente inmunosupresores tópicos (2,85%). CONCLUSIONES: Es necesario un seguimiento estrecho de los pacientes con diagnóstico clínico o anatomopatológico de BXO dada su elevada morbilidad. Las principales complicaciones descritas en la población pediátrica son la estenosis meatal y uretral, así como la recidiva de la fimosis si no se reseca el prepucio suficientemente.

ABSTRACT

INTRODUCCIÓN: La onicocriptosis o uña incarnata es una patología altamente prevalente en la población pediátrica. El abordaje quirúrgico es el tratamiento definitivo en estadios avanzados, siendo la onicectomía con matricectomía química y la mecánica las técnicas más utilizadas. El objetivo de este estudio es comparar la tasa de recidivas locales de ambas técnicas quirúrgicas. Población y métodos: Se realiza un estudio ambispectivo entre 2010 y 2017 en pacientes con diagnóstico de onicocriptosis que fueron intervenidos quirúrgicamente. Grupo A: onicectomía parcial con matricectomía química con fenol. Grupo B: matricectomía por abrasión mecánica. Se recogen variables demográficas, quirúrgicas, postoperatorias inmediatas y complicaciones a largo plazo. El análisis estadístico se realizó con el programa estadístico SPSS Statics versión 22, considerándose significación estadística un valor de p <0,05. RESULTADOS: Un total de 87 pacientes se incluyeron en el estudio. En el grupo A (12 pacientes), 2 casos (16,7%) presentaron celulitis locales postoperatorias, 4 casos (33%) presentaron recidivas ipsilaterales y uno de ellos, una segunda recidiva. En el grupo B (75 pacientes) no se describen complicaciones postoperatorias inmediatas y 7 pacientes (9%) padecieron recidivas ipsilaterales, de los cuales 3 tuvieron una segunda recidiva. Ambos grupos presentaron diferencias estadísticamente significativas en el índice de recidivas (p= 0,04). CONCLUSIÓN: En nuestra experiencia la onicectomía parcial con matricectomía mecánica por abrasión presenta una baja tasa de complicaciones y de recidivas locales respecto a la fenolización en población pediátrica. Es necesaria la realización de nuevos estudios prospectivos aleatorizados para confirmar esta diferencia


INTRODUCTION: The onychocryptosis in the pediatric population is a highly prevalent pathology. The surgical approach is the treatment of choice in advanced stages with two different techniques, onicectomy with matricectomy by chemical or mechanical abrasion. The purpose of this study is to compare the local recurrences in these two different approaches. MATERIAL AND METHODS: This is an ambispective cohort study between 2010 and 2017 in two groups. Group A: partial onicectomy with matricectomy by chemical abrasion with phenol. Group B: matricectomy by mechanical abrasion. Demographic, surgical, immediate postoperative variables and long-term complications are compared. The statics was performed with the SPSS Static 22 software. P value < 0.05 is consider statistically significant. RESULTS: The study included 87 patients. In group A (12 patients), or chemical matricectomy two cases (16.7%) presented local cellulitis, 4 cases (33%) presented a local recurrence and one of them suffered from a second recurrence. Group B (75 patients) or mechanical matricectomy, did not show immediate postoperative complications and 7 patients (9%) suffered from an ipsilateral recurrence. A second recurrence appeared in three of them. The differences in the recurrence rate between group A and B were statistically significant (p = 0.04). CONCLUSION: In our experience partial onicectomy with matricectomy by mechanical abrasion in onychocryptosis has a low rate of complications and local recurrences compared to phenolization in pediatric patients. It is necessary to perform new randomized and prospective studies to confirm this difference

ABSTRACT

Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention. Materials and methods The study cohort was obtained from the National (Nationwide) Inpatient Sample database between 2006 and 2014, using International Statistical Classification of Diseases, ninth revision discharge diagnosis and procedure codes. A total of 11,825 patients with large-vessel anterior circulation stroke treated with intravenous thrombolytic and mechanical thrombectomy on the same day were identified. The study population was subdivided into three subgroups: no carotid intervention, same-day carotid angioplasty without carotid stenting, and same-day carotid stenting. Outcomes were assessed with respect to mortality, significant disability at discharge, hemorrhagic transformation, and requirement of percutaneous endoscopic gastronomy tube placement, prolonged mechanical ventilation, or craniotomy. Results This study found no statistically significant difference in patient outcomes in those treated with concurrent carotid stenting compared to no carotid intervention in terms of morbidity or mortality. Conclusions If indicated, it is reasonable to consider concurrent carotid stenting and/or angioplasty for large-vessel anterior circulation stroke patients treated with mechanical thrombectomy who also receive intravenous thrombolytics.

ABSTRACT

UNLABELLED: Patients with rheumatoid arthritis (RA) are at increased risk of mortality compared with the general population. Evidence suggests that this increased mortality can largely be attributed to increased cardiovascular (CV) death. In a prospective study, 34 patients with RA were compared with age- and sex-matched controls. RESULTS: We found a lower C-HDL, apolipoprotein A1 and B in patients with RA. However, CT/C-HDL and C-LDL/C-HDL were significantly higher than control patients. The intima-media thickness was significantly higher in patients with RA (0.759 mm vs 0.558 mm; P<0.001). CONCLUSION: Increased attention to cardiovascular risk in RA will be necessary to reduce the excess CV mortality and morbidity in RA patients. It appears that the excess risk that is observed in the RA population can be explained, in part, by promotion of CV disease through increased systemic inflammation associated with RA.

ABSTRACT

OBJECTIVE: To evaluate the effect of IV recombinant tissue plasminogen activator (rt-PA) in patients with hyperdense artery sign (HAS) on initial CT scan. METHODS: The authors determined the differential effect of IV rt-PA (0.9 mg/kg) in patients with HAS by testing the interaction of rt-PA and HAS in a logistic regression model after adjusting for age, sex, initial NIH Stroke Scale score (NIHSSS), time to randomization, systolic blood pressure, serum glucose, body temperature, and rt-PA in 616 patients treated within 3 hours of symptom onset. Outcomes evaluated included intracranial hemorrhage, modified Rankin scale (mRS) 0-1, Barthel Index (BI) of > or = 95, Glasgow Outcome Scale (GOS) of 0-1, NIHSSS 0-1, and death at 90 days. RESULTS: HAS was detected on the initial CT scan in 91 (15%) of the 616 patients by an independent neuroradiologist. Significantly lower rates of mRS 0-1, BI > or = 95, GOS of 0-1, or NIHSSS 0-1 at 90 days were observed among patients with HAS. IV rt-PA significantly increased the rates of mRS 0-1, BI > or = 95, GOS of 0-1, or NIHSSS 0-1 at 90 days after adjusting for potential confounders without any significant modifying effect (interaction) of HAS. Among the 91 patients with HAS, rt-PA use demonstrated a trend or significance for increased adjusted rates of favorable outcomes by mRS (p = 0.04), BI (p = 0.1), GOS (p = 0.03), and NIHSSS (p = 0.01). CONCLUSION: Although hyperdense artery sign is associated with poor outcome, IV recombinant tissue plasminogen activator may be beneficial in this subgroup of patients with ischemic stroke.

ABSTRACT

BACKGROUND AND PURPOSE: The goal of this study was to evaluate the utility of perfusion-weighted CT (PWCT) in predicting final infarct volume and clinical outcome in patients with acute middle cerebral artery (MCA) stroke. METHODS: Twenty-two consecutive patients with MCA stem occlusion who underwent intra-arterial thrombolysis within 6 hours of stroke onset had noncontrast CT and CT angiography with whole-brain PWCT imaging before treatment. Infarct volumes were computed from the initial PWCT and follow-up scans; clinical outcome was measured with the modified Rankin scale. RESULTS: Initial PWCT lesion volumes correlated significantly with final infarct volume (P=0.0002) and clinical outcome (P=0.01). For the 10 patients with complete recanalization, the relationship between initial and final lesion volume was especially strong (R(2)=0.94, P<0.0001, slope of regression line=0.92). For those without complete recanalization, there was progression of lesion volume on follow-up imaging (R(2)=0.50, P=0.01, slope of regression line=1.61). All patients with either initial PWCT lesion volumes >100 mL or no recanalization had poor outcomes (Rankin scores, 4 to 6). Mean admission NIH Stroke Scale scores and mean lesion volumes in the poor outcome group were significantly different compared with the good or fair outcome (Rankin scores, 0 to 3) group (21+/-4 versus 17+/-5, P=0.05, and 106+/-79 versus 29+/-37 mL, P=0.01). Patients with initial volumes <100 mL and partial or complete recanalization all had good (Rankin scores, 0 to 2) or fair (Rankin score, 3) outcomes. CONCLUSIONS: Lesion volumes on admission PWCT images approximate final infarct volume for patients with early complete recanalization of MCA stem occlusion. For those without complete recanalization, there is subsequent enlargement of lesion volume on follow-up. Initial PWCT lesion volumes also have predictive value; volumes >100 mL are associated with a poor clinical outcome. In these highly selected patients, initial PWCT lesion volume was a stronger predictor of clinical outcome than was initial NIH Stroke Scale score.

ABSTRACT

OBJECTIVE: To investigate the causes of fever in subarachnoid hemorrhage (SAH) and examine its relationship to outcome. BACKGROUND: Fever adversely affects outcome in stroke. Patients with SAH are at risk for cerebral ischemia due to vasospasm (VSP). In these patients, fever may be both caused by, and potentiate, VSP-mediated brain injury. METHODS: The authors prospectively studied patients admitted to a neurologic intensive care unit with nontraumatic SAH, documenting Hunt-Hess grade, Fisher group, Glasgow Coma Score, bacterial culture data, daily transcranial Doppler mean velocities, and maximum daily temperatures. Patients were classified as febrile (temperature above 38.3 degrees C for at least 2 consecutive days) or afebrile (no fever or isolated episodes of temperature above 38.3 degrees C). VSP was verified by either transcranial Doppler or angiographic criteria. Rankin scale scores on discharge were dichotomized into good (0 to 2) or poor (3 to 6) outcomes. RESULTS: Ninety-two consecutive patients were studied. Thirty-eight patients were classified as febrile. No source for infection was found in 10 of 38 (26%) patients. In a multivariate analysis, three variables independently predicted fever occurrence: ventriculostomy (OR, 8.5 [CI, 2.4 to 29.7]), symptomatic VSP (OR, 5.0 [CI, 1.03 to 24.5]), and older age (OR, 1.75 per 10 years [CI, 1.02 to 3.0]). Poor outcome was related to fever (OR, 1.4 per each day febrile [CI, 1.1 to 1.88]), older age (OR, 1.64 per 10 years [CI, 1.04 to 2.58]), and intubation (OR, 21.8 [CI, 5.6 to 84.5]). CONCLUSION: Fever in SAH is associated with vasospasm and poor outcome independently of hemorrhage severity or presence of infection.

ABSTRACT

The aim of this pilot study was to determine whether the use of induced hypertension in acute stroke is feasible and associated with neurologic improvement. Phenylephrine was used to raise the systolic blood pressure in patients with acute stroke by 20%, not to exceed 200 mmHG: Of 13 patients treated, 7 improved by 2 points on the NIH Stroke SCALE: No systemic or neurologic complications were seen. The authors conclude that induced hypertension in acute stroke is feasible and likely safe and can improve the neurologic examination in some patients.

ABSTRACT

BACKGROUND AND PURPOSE: Aneurysm embolization using Guglielmi detachable coils (GDC) is gaining increasing acceptance as a viable alternative to surgery in the treatment of cerebral aneurysms. Although recent reports describe a significant rate of symptomatic thromboembolic complications with GDC use, many of the neurologic deficits are transient. We sought to determine the incidence of silent thromboembolic events with the use of diffusion-weighted imaging and to correlate radiologic findings with the results of neurologic examinations. METHODS: Diffusion-weighted MR imaging was performed within 48 hours in 14 consecutive elective GDC aneurysm treatments. Embolizations were performed under systemic heparinization; all flush solutions were heparinized, and both guiding catheters and microcatheters were placed for continuous heparinized infusions. Neurologic examination, including the National Institutes of Health Stroke Scale determination, was performed by a stroke neurologist before the coiling procedures were performed, immediately after the procedures were performed, and before discharge. MR imaging examinations were reviewed by a stroke neurologist and an interventional neuroradiologist, with determination and characterization of diffusion-weighted imaging abnormalities. RESULTS: Small areas of restricted diffusion, presumed to represent procedure-related embolic infarctions, were noted on the images of eight of 14 patients. All except one of the areas were located ipsilateral to the side of the catheterization. Six patients had evidence of multiple infarcts. Most lesions were small (<2 mm); one patient with coil stretch and herniation into the parent vessel had numerous infarcts with a dominant posterior frontal infarct. Pre- and posttreatment National Institutes of Health Stroke Scale scores were unchanged for 13 of 14 patients. Overall, the rate of asymptomatic emboli was 61% (eight of 13 treatments) in uncomplicated treatments. Strokes occurred independently of the number of coils used; the mean number of coils used for patients with strokes was 7.6 (range, two to 13) and for patients without evidence of infarcts was 10.2 (range, one to 30). This was not a significant difference (P > .5). CONCLUSION: Silent thromboembolic events related to the use of the GDC system are a common occurrence, despite meticulous technique and systemic anticoagulation. Although clinical sequelae are rare, the high rate of occurrence suggests that alterations in the technique, such as the addition of antiplatelet agents, should be considered.

ABSTRACT

Cholesterol emboli (CE) to the brain are an important but often unrecognized cause of stroke. The authors reviewed 29 cases of brain CE identified on autopsy. Most patients were elderly (mean age, 74 years) and presented with encephalopathy and acute renal failure. Ten patients developed symptoms spontaneously, 19 after a procedure involving manipulation of the aorta. Brain imaging revealed multiple, small ischemic lesions and border zone infarcts in 11 of 17 patients. Pathology in most patients demonstrated multiple CE mixed with emboli of other types.

ABSTRACT

BACKGROUND AND PURPOSE: Small infarcts in the territory of penetrator arteries were described as causing a number of distinct clinical syndromes. The vascular pathophysiology underlying such infarcts is difficult to ascertain without careful pathological study. However, the occurrence of multiple, small infarcts, linked closely in time but dispersed widely in the brain, raises the possibility of an embolic mechanism. The current study determines the frequency and clinical characteristics of patients with well-defined lacunar syndromes and the diffusion-weighted imaging (DWI) evidence of multiple acute lesions. METHODS: Sixty-two consecutive patients who presented to the emergency room with a clinically well-defined lacunar syndrome were studied by DWI within the first 3 days of admission. RESULTS: DWI showed multiple regions of increased signal intensity in 10 patients (16%). A hemispheric or brain stem lesion in a penetrator territory that accounted for the clinical syndrome ("index lesion") was found in all. DWI-hyperintense lesions other than the index lesion ("subsidiary infarctions") were punctate and lay within leptomeningeal artery territories in the majority. As opposed to patients with a single lacunar infarction, patients with a subsidiary infarction more frequently (P<0.05) harbored an identifiable cause of stroke. CONCLUSIONS: Almost 1 of every 6 patients presenting with a classic lacunar syndrome has multiple infarctions demonstrated on DWI. This DWI finding usually indicates an identifiable cause of stroke and therefore may influence clinical decisions regarding the extent of etiologic investigations and treatment for secondary prevention.
