This study retrospectively analyzes all consecutive patients who underwent during a year hospital readmissions, defined as an admission to a hospital within 30 days of discharge, to an Italian Internal Medicine ward. All these data were compared with those from patients who underwent only 1 hospital admission in the same period. The aim of this study was to identify potential novel risk factors for hospital readmissions. In 2018, a total of 3012 patients were hospitalized. Among these, 14.1% (n = 426; mean age, 79.7 ± 11.9; range, 23-100) were defined as readmissions; data were compared with controls (n = 420; 13.9%; mean age, 75.9 ± 14.7; range, 22-99) who had only 1 hospitalization. Cases showed a significantly higher prevalence than controls regarding cerebrovascular disease (77.2% vs 48.1%), cognitive impairment (51.8% vs 26.9%), congestive heart failure (47.6% vs 20.2%), chronic kidney disease (31.7% vs 13.1%), and chronic obstructive pulmonary disease (23.0% vs 14.5%). Skin ulcers were significantly more prevalent among cases (45.1% vs 17.6%). Diagnosis-related group (DRG) analysis showed a higher proportion of "infectious disease" (24.4% vs 15.0%) among the cases than in controls. Despite skin ulcers were very frequent among cases and controls (45.1% vs 17.6%), they were codified as "skin wound" DRG only in 1.4% and 0.2%, respectively. At the DRGs analysis, sepsis (31.6% vs 19.1%), pneumonia (17.1% vs 7.6%), and kidney failure (9.6% vs 3.8%) represented the main significant cause of death in cases compared to controls. Our study confirms that readmissions to Internal Medicine departments are related to the severity of chronic diseases affecting patients. Skin ulcers are present in about half of patients who will be early readmitted within 30 days, but they are almost never reported in DRGs, so more accurate coding is needed. Key challenges for the future are sepsis prevention measures and investing resources in chronic disease assistance, including skin ulcer chronic management.

Background: To allay uneasiness among clinicians and institutional review board members about pediatric palliative care research and to yield new knowledge relevant to study methods, documenting burdens and benefits of this research on children and their families is essential. Design: In a grounded theory study with three data points (T1, T2, and T3), we evaluated benefits and burdens of family caregiver participation at T3. English-speaking caregivers participating in palliative or end-of-life decisions for their child with incurable cancer or their seriously ill child in the intensive care unit participated. Thirty-seven caregivers ( n  = 22 from oncology; n  = 15 from intensive care) of 33 children completed T3 interviews; most were mothers ( n  = 25, 67.6%), African American ( n  = 18, 48.6%), and married ( n  = 28, 75.7%). Measurement: Benefits and burdens were assessed by three open-ended questions asked by an interviewer during a scheduled telephone contact. Responses were analyzed using descriptive semantic content analysis techniques and themes were extracted. Results: All 37 T3 participants completed the 3 questions, resulting in no missing data. The most frequently reported themes were of positive personal impact: "Hoping to help others," "Speaking about what is hard is important," and "Being in the study was sometimes hard but not bad." Conclusions: No caregiver described the study as burdensome. Some acknowledged that answering the questions could evoke sad memories, but highlighted benefits for self and others. Attrition somewhat tempers the emphasis on benefits. Documenting perceived benefits and burdens in a standardized manner may accurately convey impact of study participation and yield new knowledge.

Purpose: To clarify the possible role of other factors including the ApoE epsilon4 allele for memory decline in temporal lobe epilepsy (TLE)., Methods: We conducted a neuropsychological and molecular study in 138 consecutive patients (78 female patients; mean age, 50.2 years, SD +/- 17.9; range, 14 to 87 years) with mild nonlesional TLE, who rarely or never had seizures at long-term follow-up. The mean age at seizure onset was 33.0 years (SD, +/-21.7), and the mean duration of epilepsy was 17.1 years (SD, +/-15.7)., Results: Thirty-four (25%) of 138 patients had test scores indicating verbal learning deficit (VLD). The presence of an ApoE epsilon4 allele was associated with an increased risk of VLD (OR, 4.18; 95% CI, 1.66-10.55). The effect of the ApoE genotype was independent of both the age at epilepsy onset and disease duration as well as of a low educational level, which were separately associated with VLD (p values = 0.045, 0.001, and 0.001, respectively). A significant linear trend (p = 0.005) was seen in the relation between disease duration and cognitive impairment, with the highest risk being in patients with an epilepsy duration > or =25.5 years (OR, 7.06; 95% CI, 1.67-29.85), especially if they carried the epsilon4 allele (OR, 32.29; 95% CI, 5.23-195.72)., Conclusions: These results provide evidence for an alteration in cognitive performance as a function of the presence of the ApoE epsilon4 allele and point to the critical role of disease duration itself for cognitive impairment in TLE.

Objective: To report on five patients with temporal lobe epilepsy (TLE) as the unique manifestation of multiple sclerosis (MS)., Methods: Among 350 consecutive MS patients, we identified 16/350 (4.6%) who also had epileptic seizures. Here, we review their electrophysiological and clinical features., Results: Five of these 16 patients (four female, one male; mean age 34.2 years; range 31 to 38) with MS and epileptic seizures had an extremely homogeneous clinical picture characterized by TLE as the unique manifestation of MS, even at long follow-up (mean: five years; range 4 to 10). In all patients, seizures started in the second or third decade. Brain MRI revealed at least one juxta-cortical lesion within the temporal region. Antiepileptic medication was always effective., Conclusions: The present study provides the first evidence of a peculiar form of MS characterized by TLE as the unique manifestation of the disease with no disability or MS relapses at long-term follow-up.

Purpose: To evaluate whether the inheritance of the apolipoprotein E (ApoE) epsilon4 allele is a risk factor for nonlesional temporal lobe epilepsy (TLE), and to determine whether the newly described -491 A/T ApoE polymorphism may independently affect the risk of nonlesional TLE., Methods: The study group consisted of 63 patients (35 women and 28 men; age at onset of epilepsy, 30.6 +/- 19.6 years; mean (+/-SD). All of them had received a diagnosis of nonlesional TLE after a detailed clinical, electroencephalographic, and brain magnetic resonance investigation. The ApoE polymorphisms were determined from blood samples by standard methods. The molecular study also was performed in 220 age- and sex-matched normal individuals., Results: There were no differences between TLE patients and controls in either allelic or genotypic frequencies of the ApoE and -491A/T polymorphisms. Moreover, no effect of ApoE or -491A/T polymorphisms was found on the age at onset and severity of epilepsy., Conclusions: The allelic and genotypic frequencies of ApoE polymorphisms in Italian patients with nonlesional TLE are comparable to control values, indicating that ApoE polymorphisms are not a significant genetic risk factor for the occurrence of nonlesional TLE.

Objectives: The APOE gene polymorphism and the -491 A/T polymorphism in its regulatory region have been associated with an increased risk for developing Alzheimer's disease. We examined these polymorphisms in multiple sclerosis (MS) patients, to determine if a genetic predisposition may explain the risk for developing cognitive decline in MS., Material and Methods: Eighty-nine relapsing-remitting and secondary progressive MS patients underwent to a full neuropsychological battery as well as to determination of APOE and -491 A/T polymorphisms. Genetic analysis was also performed in 107 population controls., Results: The APOE polymorphism was not associated with the risk of cognitive impairment in MS patients. The AA genotype of the -491 A/T polymorphism in the APOE regulatory region was more frequent in cognitively impaired than in cognitively preserved MS subjects., Conclusion: The AA homozygous state of the -491 A/T polymorphism of the APOE regulatory region is associated with cognitive impairment in patients with MS.

Objective: To assess the efficacy of two different high doses of intravenous methylprednisolone (IVMP) for the treatment of relapses in MS., Background: IVMP is the treatment of choice for MS relapses, but it is unknown whether its effects are dose related., Methods: We conducted a double-blind, randomized study. Follow-up included serial clinical and MRI recordings at baseline and at 7, 15, 30, and 60 days after the beginning of treatment. Outcome measures were the number of brain and cervical spinal cord MRI contrast-enhancing lesions, and the Expanded Disability Status Scale score., Results: Both treatment regimens improved clinical scores and reduced the number of MRI enhancing lesions during the follow-up period. The higher dose of IVMP was significantly more effective than the lower dose in reducing the number of MRI contrast-enhanced lesions at 30 and 60 days, mainly by decreasing the rate of new lesion formation., Conclusions: The higher dosage of IVMP has a more powerful and prolonged action in maintaining blood-brain barrier integrity after a clinical relapse.

Objective: Chronic administration of corticosteroids has been reported to selectively impair explicit memory in systemic diseases without central nervous system involvement. Our aim was to verify that a short course of pulsed intravenous methylprednisolone (IVMP) administered for the treatment of a relapse impairs cognitive functions in relapsing-remitting multiple sclerosis (RRMS) patients and to determine whether this impairment is reversible., Material and Methods: Neuropsychological evaluations were made before the start of treatment, and 7 and 60 days after the end of treatment in 14 RRMS patients. The neuropsychological battery was also administered to 12 controls matched for age, sex and years of education., Results: RRMS patients performed worse than the controls at their baseline evaluation for a variety of neuropsychological tasks. IVMP administration induced a selective impairment of explicit memory which completely recovered 60 days after treatment., Conclusions: In RRMS patients, IVMP induces a selective and reversible impairment of explicit memory.

In order to quantify the decline in renal function, repeated measurements of GFR are necessary. The conventional procedure is cumbersome and time expending so that alternative clearance techniques are needed. We propose a simple isotopic technique for measuring GFR by 99mTc-DTPA and external counting of the bladder by gamma camera (bladder cumulative method). This consists in the measurement by external counting of the amount of labelled filtration marker accumulated in the bladder after intravenous bolus injection. In 36 adult patients with all degrees of renal impairment (serum creatinine 0.9-9.3 mg/dL) GFR was measured twice, once by the conventional method (continuous i.v. infusion of the filtration marker and urine collection by spontaneous voiding) and once by the bladder cumulative method. 99mTc DTPA was used in performing both methods. A satisfactory agreement was found between GFR measured by bladder cumulative method (BCM) and by conventional method (CM). The BCM averaged 60.0 +/- 36.7 mL/min and the CM +/- SD averaged 62.8 +/- 36.6 mL/mm. The ratio BCM/CM +/- SD was 0.95 +/- 0.14 (y = 0.94x + 1.14; r = 0.94). Considering the 17 patients with renal insufficiency (GFR < 60 mL/min) an even better agreement between the two methods was found. In these patients the BCM averaged 28.4 +/- 17.2 mL/min; the CM averaged 29.1 +/- 16.6 mL/min; and the ratio BCM/CM was 0.96 +/- 0.08 (y = 1.03x - 1.47; r = 0.99). The day-to-day variability of BCM, studied in another 11 patients, was lower than that of creatinine clearance (variation coefficient for duplicate measurements: 7.18 +/- 6.65 SD for BCM, 15.68 +/- 8.80 SD for CM, p < 0.01). The bladder cumulative method is a simple procedure for the accurate measurement of GFR, in particular in patients with renal insufficiency. It represents a reliable tool for estimating the decline in renal function.

The QTc dispersion reflects the underlying regional heterogeneity of the recovery of the ventricular excitability, thereby it is considered as a novel marker of risk of ventricular arrhythmias. Because a higher incidence of ventricular arrhythmias is described during and after hemodialysis, the aim of this study has been to evaluate the QTc dispersion before and after uncomplicated hemodialysis session. Twenty chronic uremics without heart failure, ischemic heart disease or dialysis hypotension were selected. The QTc dispersion was determined as the difference between the longer and the shorter QTc interval measured on a 12-lead electrocardiogram. Following the hemodialysis session, the QTc dispersion increased from 30 +/- 9 to 54 +/- 17 ms (p < 0.001) associated with the expected reduction of potassium and magnesium and with the increase of extracellular calcium concentration. However, no correlation has been observed between the QTc dispersion increase and the degree of the intradialytic changes of plasma electrolytes, blood pressure or body weight. In summary, the hemodialysis treatment per se does induce an increase of the QTc dispersion, likely due to the rapid changes of electrolyte plasma concentrations. This can potentially contribute to the arrhythmogenic effect of the hemodialysis procedure, reflecting an enhanced regional heterogeneity of ventricular repolarization. The clinical importance of the increase of QTc dispersion as risk factor of ventricular arrhythmias, particularly in hemodialyzed patients suffering from ischemic or hypertrophic heart diseases, should be the matter of further investigations.
