Presence of Increased Mast Cells in Infants and Children with Volume and Variety Limited Intake

Background: Reports indicate patients with feeding difficulties demonstrate signs of inflammation on biopsies, notably eosinophilia, but it is unknown whether mast cell density contributes to variety or volume limitation symptoms. The aim of our study was to evaluate eosinophil and mast cell density of EGD biopsies in pediatric patients with symptoms of decreased volume or variety of ingested foods. Methods: We conducted a single-center, retrospective chart review of EMRs for all new feeding clinic patients between 0 and 17 years of age. Patients were categorized by symptoms at the initial visit as well as eosinophil and mast cell densities in those with EGD biopsies. Ten patients were identified as controls. Results: We identified 30 patients each with volume and variety limitation. Antral mast cell density was increased in 32.1% of variety-limited patients, 37.5% of volume limited patients, and in no controls; Duodenal mast cell density was increased in 32.1% of variety-limited patients, 40.6% of volume-limited patients, and in no controls. Conclusions: In both variety- and volume-limited patients, antral and duodenal mast cell densities were increased. These associations warrant further investigation of the mechanism between mast cells and development of feeding difficulties, allowing more targeted pediatric therapies.     

Gender differences,outcomes and trends among nonagenarian with atrial fibrillation: insight from National Inpatient Sample database

BACKGROUND Nonagenarians(NG),individuals aged≥90 years,constitute an increasing proportion of hospitalizations presenting with atrial fibrillation(AF).However,not much is known about demographics,clinical outcomes,and trends of hospitalizations.Therefore,we analyzed data about hospitalizations and clinical outcomes among NGs with AF over ten years from 2005 to 2014 using a publically available database,the National Inpatient Sample.METHODS All hospitalizations and major outcomes of subjects≥90 years with a primary diagnosis of AF(ICD-9-CM code 427.31)over a ten-year period were assessed in this study by multivariate logistic regression analysis.RESULTS There were more females than males(176,268 females,51,384 males)in this analysis.The number of hospitalizations for AF among NG increased by 50%(17,295 in 2005 to 25,830 in 2014).Males were more likely to undergo cardioversion(6.14%of males vs.5.06%of females,P<0.0001).Over this period,in-hospital mortality declined from 3.21%in 2005 to 2.38%in 2014(P=0.0041),with higher in-hospital mortality in males(3.23%in males vs.2.76%in females,P=0.0138),mean length of hospitalization decreased from 4.53 days to 4.13 days(P<0.0001),the prevalence of congestive heart failure fell from 0.48%to 0.23%(P=0.0257),and the use of anticoagulation increased from 6.09%to 14.54%(P<0.0001).In a multivariate analysis,hospital admission on the weekend,Elixhauser comorbidity index,CHA2DS2VASc score,acute respiratory failure,and the length of hospital stay were associated with a higher risk of in-hospital mortality.CONCLUSIONS From 2005 to 2014,AF-related hospitalizations among NGs increased,more so in in females population,mortality trends improved,rates of anticoagulation increased,and cardioversions increased.Despite the decreasing trend of in-hospital mortality since 2005,the relatively high mortality rate in males warrants further studies.     

Lésions kystiques cérébrales : Pensez au kyste hydatique

Background. Hydatidosis is an endemic parasitosis in Tunisia that affect mostly the liver and the lung. Brain involvment is rare. Aim. To focus on diagnostic, therapeutic and evolutive characteristics of cerebral hydatidosis. Methods. We report all cases of cerebral hydatidosis seen in the infectious diseases and neurosurgery departments between January 2013 and June 2020. Results. Six cases of intracranial hydatid cyst were reported. The male to female ratio was 3:3. Age ranged from 3 to 60 years with a median age of 20,5 years. All patients lived in rural areas. The clinical symptomatology was progressive in 4 cases. It was dominated by headache (all cases). Brain imaging confirmed the diagnosis in all cases. The hydatid cyst was solitary and supratentorial in 3 cases. All the patients were operated. Albendazole was prescribed immediately after surgery, for 6 months in 5 cases and for 3 years in the case of disseminated hydatidosis. The outcome was favorable without recurrence in all patients with an average follow-up of 3,5 ± 0,5 years. Conclusion. Hydatid cyst of the brain is characterized by the severity of the neurological signs, the mandatory use of surgery because of life threatening and the excellent outcomes.     

In vivo measurement of the apparent diffusion coefficient in normal and malignant prostatic tissues using echo-planar imaging

PURPOSE: To measure for the first time the apparent diffusion coefficient (ADC) values in anatomical regions of the prostate for normal and patient groups, and to investigate its use as a differentiating parameter between healthy and malignant tissue within the patient group. MATERIALS AND METHODS: Single-shot diffusion-weighted echo-planar imaging (DW-EPI) was used to measure the ADC in the prostate in normal (N = 7) and patient (N = 19) groups. The spin-echo images comprised 96 x 96 pixels (field of view of 16 cm, TR/TE = 4000/120 msec) with six b-factor values ranging from 64 to 786 seconds/mm(2). RESULTS: The ADC values averaged over all patients in non-cancerous and malignant peripheral zone (PZ) tissues were 1.82 +/- 0.53 x 10(-3) (mean +/- SD) and 1.38 +/- 0.52 x 10(-3) mm(2)/second, respectively (P = 0.00045, N = 17, paired t-test). The ADC values were found to be higher in the non-cancerous PZ (1.88 +/- 0.48 x 10(-3)) than in healthy or benign prostatic hyperplasia central gland (BPH-CG) region (1.62 +/- 0.41 x 10(-3)). For the normal group, the mean values were 1.91 +/- 0.46 x 10(-3) and 1.63 +/- 0.30 x 10(-3) mm(2)/second for the PZ and CG, respectively (P = 0.011, N = 7). Significant overlap exists between individual values among all tissue types. Furthermore, ADC values for the same tissue type showed no statistically significant difference between the two subject groups. CONCLUSION: ADC is quantified in the prostate using DW-EPI. Values are lower in cancerous than in healthy PZ in patients, and in BPH-CG than PZ in volunteers.     

Desnutrição e Caquexia na Insuficiência Cardíaca Descompensada e Cardiomiopatia Chagásica: Ocorrência e Associação com Desfechos Hospitalares

BackgroundNutritional disorders are common among patients with heart failure (HF) and associated with poor prognosis. Importantly, some populations of patients, like the ones with Chagas disease, are frequently excluded from most analyses.ObjectiveWe sought to study the occurrence of undernutrition and cachexia in patients with Chagas disease during episodes of decompensated HF (DHF) as compared to other etiologies, and to investigate the influence of these findings on hospital outcomes.MethodsWe performed a consecutive case series study with patients hospitalized with DHF. Patients underwent the Subjective Global Assessment of nutritional status (SGA), besides anthropometric and laboratorial measures, and were evaluated for the occurrence of cachexia, low muscle mass and strength. We studied the occurrence of death or urgent heart transplantation during hospitalization.ResultsAltogether, 131 patients were analyzed and 42 (32.1%) had Chagas disease. Patients with Chagas disease had lower Body Mass Index (BMI) (22.4 kg/m²[19.9-25.3] vs. 23.6 kg/m2 [20.8-27.3], p=0.03), higher frequency of undernutrition (76.2% vs 55.1%, p=0.015) and higher occurrence of death or transplant (83.3% vs. 41.6%, p<0.001). We found that, in patients with Chagas etiology, the occurrence of death or cardiac transplantation were associated with undernutrition (3 [42.9%] patients with hospital discharge vs 29 [82.9%] patients with death or heart transplant, p=0.043).ConclusionsTaken together, our results indicate that patients with Chagas disease hospitalized with DHF often present with nutritional disorders, especially undernutrition; importantly, this finding was associated with the occurrence of death and heart transplant during hospitalization.     

Epidemiology of traumatic injuries to the permanent incisors of 9–12-year-old school children in Damascus, Syria

Abstract— This cross-sectional survey was carried out to assess epi-demiological data concerning dental injuries to the permanent incisors of Syrian children. It included 1087 children aged 9 to 12 years, of both sexes, randomly selected from public and private primary schools in Damascus. The response rate was 100%. The prevalence of traumatic injuries to the permanent incisors rose from 5.2% at the age of 9 years to 11.7% at the age of 12 years ( P= 0.007). The difference in prevalence between boys and girls was not statistically significant ( P>0.05 ). The majority (59.8%) of children who had experienced injuries to the permanent incisors reported that they were not taken to the dentist for evaluation or treatment of the damage. Among those children who had experienced traumatic injuries to the teeth 93.1% presented with untreated damage. Because some injuries were minor, such as small enamel fractures, the proportion of children who needed treatment was 63.2%. There was a tendency for children with an incisal overjet greater than 5 mm to have experienced dental injuries ( P=0.06 ). Children with inadequate lip coverage were more likely to have experienced dental injuries than those with adequate lip coverage (P=0.000). The most common reported cause of injuries to the permanent incisors was violence (42.5%), followed by traffic accidents (24.1%), collisions with people or inanimate objects (16.0%) and falls (9.1%). In conclusion, traumatic dental injury may pose a serious dental public health problem.
