Neuropsychiatric Questionnaires in Systemic Lupus Erythematosus

Patients with systemic lupus erythematosus (SLE) can be affected by a multitude of neurologic and psychiatric symptoms with a wide range of prevalence and severity. Irrespectively from attribution to SLE or other causes, neuropsychiatric (NP) symptoms strongly impact short-term and long-term outcomes,thus NP evaluation during routine clinical practice in SLE should be undertaken regularly. The assessment of NP involvement in SLE patients is challenging and the available diagnostic tools fail to guarantee optimal diagnostic accuracy, sensitivity to changes as well as feasibility in routine clinical care. Standardised questionnaires (both physician-administered and self-reported) can offer valuable help to the treating physician to capture all possible NP syndromes; few SLE-specific NP questionnaire have been developed but validation in large cohort or cross-cultural adaptations are still pending. On the other hand, general instruments have been largely applied to SLE patients. Both kinds of questionnaires can address all possible NP manifestations either globally or, more frequently, focus on specific NP symptoms. These latter have been mainly used in SLE to detect and classify mild and subtle symptoms, more likely to be overlooked during routine clinical assessment such as headache, cognitive impairment and psychiatric manifestations. In conclusion, this literature review highlights a clear case for validation studies in this area and the wider implementation of questionnaires to assess NP involvement is still warranted. The broader use of such instruments could have important consequences; first of all, by standardising symptom assessment, a better definition of the prevalence of NP manifestation across different centres could be achieved. Secondly, prospective studies could allow for the evaluation of clinical significance of mild symptoms and their impact on the patient’s function and quality of life.

Long-Term Lamivudine Treatment of Children with Chronic Hepatitis B: Durability of Therapeutic Responses and Safety

Lamivudine has been demonstrated safe and efficacious in the short term in a large cohort of children with chronic hepatitis B (CHB), but optimal duration of treatment has not been elucidated and limited data on the safety of long-term lamivudine administration have been reported. In addition, the durability of favourable therapeutic outcomes after lamivudine therapy in children has not been well characterized. The aim of this study was to examine the safety of lamivudine and the durability of clinical responses in a group of children who received up to 3 years of treatment for CHB. One hundred and fifty-one children from centres in nine countries who had previously received lamivudine in a large prospective trial were enrolled. During the first year, children had been randomized to either lamivudine or placebo treatment. Subsequently, in a separate extension study, those who remained hepatitis B e antigen (HBeAg) positive were given lamivudine for up to 2 years and those who were HBeAg negative were observed for additional 2 years. Results of these studies have been previously reported. In this study, these children were followed for 2 additional years. Data gathered from medical record review included weight, height, signs and symptoms of hepatitis, alanine aminotransferase (ALT) levels, serologic markers, hepatitis B virus (HBV) DNA levels and serious adverse events (SAEs). Other pharmacological treatments for CHB were allowed according to the practices of individual investigators and were documented. Subjects were divided into two groups for analysis, those who had achieved virological response (VR), defined as HBeAg negative and undetectable HBV DNA by the bDNA assay by the end of the extension study at 3 years, and those who had not. In those who had achieved VR by the end of the extension study, long-term durability of HBeAg seroconversion was 82% and >90% in those who had received lamivudine for 52 weeks and at least 2 years respectively. This compares to 75% for those who had achieved seroconversion after placebo. In those who had not achieved VR by the end of the extension study, an additional 11% did so by the end of the study; they had all received lamivudine in the previous trial, and none had received further treatment during the study. Eight children lost hepatitis B surface antigen during the study and all had received lamivudine at some point during the previous trials. Evaluation of safety data revealed no SAEs related to lamivudine. There was no effect of treatment on weight or height z scores. Clinically benign ALT flares (>10 times normal) were seen in 2% of children. Favourable outcomes from lamivudine treatment of CHB in children are maintained for at least several years after completion of treatment. Up to 3 years of lamivudine treatment is safe in children.

Infective Endocarditis Complicated by Large Aortic Pseudoaneurysm after Cardiac Surgery

A 66-year-old female with Streptococcus viridans aortic and tricuspid infective endocarditis develops, during the course of antibiotic therapy, rupture of a right coronary sinus of Valsalva aneurysm to the right ventricle. An urgent cardiac surgery is preformed with implantation of a mechanical aortic prosthesis and a right coronary sinus plasty. Six months later a huge aortic pseudoaneurysm is diagnosed and she is submitted to a second uneventful surgery. A review is done for the significant features with discussion of diagnosis and therapy.

Transformation of a Cutaneous Follicle Center Lymphoma to a Diffuse Large B-Cell Lymphoma - An Unusual Presentation

Primary cutaneous follicle center lymphoma (PCFCL) is characterized by a proliferation of follicle center cells in the skin. A definitive diagnosis is frequently delayed because of difficulties in interpretation of the histopathologic findings. It has an excellent prognosis with a 5-year survival over 95% and its risk of transformation has not been established. We describe a case report of man with a gastric diffuse large B-cell lymphoma (DLBCL) referred to our clinic because of nodules in the back that had gradually developed over a period of 10 years. A biopsy performed 3 years before was interpreted as reactive follicular hyperplasia. A new skin biopsy revealed a diffuse large B-cell lymphoma and immunoglobulin heavy chain gene rearrangements from the initial skin biopsy (PCBCL) and the DLBCL gastric biopsy were studied by polymerase chain reaction and an identical clonal rearrangement was detected which was highly suggestive of a transformation lymphoma.

Reconstruction of Large Defect of Foot with Extensive Bone Loss Exclusively Using a Latissimus Dorsi Muscle Free Flap: a Potential New Indication for this Flap

In cases of extensive damage to the foot, with significant bone loss, it is generally accepted that reconstruction must include bone flaps or grafts either in the emergency setting or subsequently. In this report, we describe the case of an 18-year-old student with an avulsion injury of the dorsum of his right foot. Consequently, he lost most of the soft tissue over the dorsum of the foot and the cuboid, navicular, and cuneiform bones. A latissimus dorsi free flap was used to reconstruct the defect. A functional pseudoarthrosis developed between the remaining bones of the foot, and the patient experienced satisfactory foot function after rehabilitation. For this reason, no additional reconstructive procedure was undertaken. This case suggests that it might be adequate to use the latissimus dorsi muscle flap more liberally than previously reported in the reconstruction of extensive defects of the dorsum of the foot, including cases with significant bone loss. This option could avoid the morbidity and inconvenience of a second surgery and the need to harvest a bone flap or graft.

Abdominoplasty and Thoraco-Epigastric Flaps for Large Anterior Trunk Defects after Dermatofibrosarcoma Protuberans Wide Resection: Two Illustrative Cases

INTRODUCTION: Excision of large dermatofibrosarcoma protuberans in the anterior aspect of the trunk often results in large surgical defects that frequently dictate the need for microsurgical reconstruction. However, this option is not always available. PRESENTATION OF CASE: The authors describe two patients with very large anterior trunk dermatofibrosarcoma protuberans: one in the epigastric region and the other in the hypogastric region. In the patient with the hypogastric tumor, a classical abdominoplasty flap associated with umbilical transposition was used to cover the skin defect after muscle and fascial plication, and placement of a polypropylene mesh. In the patient with the epigastric tumor, a synthetic mesh was also placed, and the skin and subcutaneous defect was reconstructed with a reverse abdominoplasty flap and two thoraco-epigastric flaps. In both cases, complete closure was possible without immediate or late complications. DISCUSSION: The local options described in this paper present several potential advantages compared to microsurgical reconstruction, namely they are easier and faster to perform and teach; they provide a good skin color and texture match; they are not associated with distant donor site morbidity; follow-up is usually less cumbersome; the post-operative hospital stay tends to be shorter; they are less costly; they are less prone to complete failure. CONCLUSION: The authors believe that these two patients clearly show that local flaps, although frequently neglected, continue to be valid options for reconstructing large anterior trunk defects, even in the current era of microsurgery enthusiasm.

Perinatal Outcome and Change in Body Mass Index in Mothers of Dichorionic Twins: a Longitudinal Cohort Study

We used a prospective cohort to analyze the effect of change in BMI rather than change in weight, in mothers carrying dichorionic twins from a population that did not receive any dietary intervention. A total of 269 mothers (150 nulliparas and 119 multiparas) were evaluated. The average change (%) from the pre-gravid BMI was 7.2+/-6.1, 17.4+/-8.2, and 28.7+/-10.8, at 12-14, 22-25, and 30-34 weeks, respectively, without difference between nulliparas and multiparas. The comparison between maternities below or above the average change from the pregravid BMI failed to demonstrate an advantage (in terms of total twin birthweight and gestational age) of an above average change from the pregravid BMI, even when the lower versus upper quartiles were compared. Our observations reached different conclusions regarding the recommended universal dietary intervention in twin gestations. A cautious approach is advocated towards seemingly harmless excess weight gain, as normal weight women may turn overweight, or even obese, by the end of pregnancy, and be exposed to the untoward effects of obesity on future health and body image.

Late Stillbirth: a Ten Year Cohort Study

Introduction: Late fetal death is a desolating event that inspite the effort to implement new surveillance protocols in perinatal continues to defy our clinical pratice. Objective: To examine etiological factors contributing to main causes and conditions associated with fetal death in late pregnancies over a 10-year period. Methods: Retrospective cohort analysis of 208 late singleton stillbirth delived in a tertiary-perinatal referral maternity over a 10-year period. Clinical charts, laboratory data and feto-placental pathology findings were systematically reviewed. Results: The incidence of late fetal demise was 3.5 per 1000 pregnancies. No significant trend in the incidence of stillbirth was demonstrated during the study period. Stillbirth was intrapartum in 12 (5.8%) cases and 72 (35%) were term pregnancies. Fourteen percent of cases were undersurveilled pregnancies. Mean gestacional age at diagnosis was 34 weeks. The primary cause of death was fetal, it was present in 59 cases, 25% were considered small for gestational age. Stillbirths were unexplained in 24.5% of cases. Maternal medical disorders were identified in 21%. Hypertensive disorders were frequent and associated with early gestacional age (p = 0.028). Conclusion: There was no change in the incidence of late stillbirth during the 10 years under evaluation. The incidence was 3.5 ‰ which was identical to that described in developed countries. About one quarter of the stillbirths was unexplained. The most frequent maternal pathology was chronic hypertension.

Sepsis Mortality Prediction Based on Predisposition, Infection and Response

OBJECTIVE: To empirically test, based on a large multicenter, multinational database, whether a modified PIRO (predisposition, insult, response, and organ dysfunction) concept could be applied to predict mortality in patients with infection and sepsis. DESIGN: Substudy of a multicenter multinational cohort study (SAPS 3). PATIENTS: A total of 2,628 patients with signs of infection or sepsis who stayed in the ICU for >48 h. Three boxes of variables were defined, according to the PIRO concept. Box 1 (Predisposition) contained information about the patient's condition before ICU admission. Box 2 (Injury) contained information about the infection at ICU admission. Box 3 (Response) was defined as the response to the infection, expressed as a Sequential Organ Failure Assessment score after 48 h. INTERVENTIONS: None. MAIN MEASUREMENTS AND RESULTS: Most of the infections were community acquired (59.6%); 32.5% were hospital acquired. The median age of the patients was 65 (50-75) years, and 41.1% were female. About 22% (n=576) of the patients presented with infection only, 36.3% (n=953) with signs of sepsis, 23.6% (n=619) with severe sepsis, and 18.3% (n=480) with septic shock. Hospital mortality was 40.6% overall, greater in those with septic shock (52.5%) than in those with infection (34.7%). Several factors related to predisposition, infection and response were associated with hospital mortality. CONCLUSION: The proposed three-level system, by using objectively defined criteria for risk of mortality in sepsis, could be used by physicians to stratify patients at ICU admission or shortly thereafter, contributing to a better selection of management according to the risk of death.

Investigation and Control of a Large Outbreak of Multi-Drug Resistant Tuberculosis at a Central Lisbon Hospital

An increase in the number of new cases of tuberculosis (TB) combined with poor clinical outcome was identified among HIV-infected injecting drug users attending a large HIV unit in central Lisbon. A retrospective epidemiological and laboratory study was conducted to review all newly diagnosed cases of TB from 1995 to 1996 in the HIV unit. Results showed that from 1995 to 1996, 63% (109/173) of the Mycobacterium tuberculosis isolates from HIV-infected patients were resistant to one or more anti-tuberculosis drugs; 89% (95) of these were multidrug-resistant, i.e., resistant to at least isoniazid and rifampicin. Eighty percent of the multidrug-resistant strains (MDR) available for restriction fragment length polymorphism (RFLP) DNA fingerprinting clustered into one of two large clusters. Epidemiological data support the conclusion that the transmission of MDR-TB occurred among HIV-infected injecting drug users exposed to infectious TB cases on open wards in the HIV unit. Improved infection control measures on the HIV unit and the use of empirical therapy with six drugs once patients were suspected to have TB, reduced the incidence of MDR-TB from 42% of TB cases in 1996 to 11% in 1999.

Neuropsychiatric Features of a Cohort of Patients with Systemic Lupus Erythematosus

In order to establish if neuropsychiatric systemic lupus erythematosus (NPSLE) can be identified by any characteristic other than those used to diagnose the neuropsychiatric (NP) disease itself, we retrospectively reviewed 98 systemic lupus erythematosus (SLE) patients followed over a mean period of 10 years. NPSLE was identified in 22 patients. Stroke and generalized seizures were the most frequent NP manifestations. The NPSLE and non-NPSLE groups were similar with regard to demographic characteristics, ACR criteria, serum autoantibodies, and frequency of hypertension and hypercholesterolemia. Of note, compared to the non-NPSLE group, NPSLE was associated with a higher frequency of smoking (78 versus 26%), organ damage (73 versus 34%), and cumulative mortality rate (14 versus 7%). The series of patients was further analysed according to the presence of antiphospholipid syndrome (APS). Significantly, the interval between the onset of NP disease and SLE diagnosis was shorter in the APS(-) (0.3 ± 1 years) than in the APS(+) (5 ± 7 years) groups. Recurrence and/or persistence of NP events were only documented in the APS(-) group. Overall cumulative mortality was highest in NPSLE and in APS(+) patients with inadequate anticoagulation control, identifying an aspect that requires improved vigilance and the development of novel therapeutic modalities.

Juvenile Systemic Lupus Erythematosus in Portugal: Clinical and Immunological Patterns of Disease Expression in a Cohort of 56 Patients

Objective: To define the pattern of disease expression and to gain better understanding in patients with juvenile onset systemic lupus erythematosus (SLE) in Portugal. Methods: The features of unselected patients with systemic lupus erythematosus who had disease onset before the age of 18 years were retrospectively analysed in three Portuguese centres with Pediatric Rheumatology Clinic over a 24-year period (1987-2011). Demographic, clinical and laboratory manifestations, therapy and outcome were assessed. Results: A cohort of 56 patients with a mean age at disease onset of 12.6±4.04 years (mean±1SD) (range, 1.0-17.0 years) and a mean period of follow-up of 5.5±5.4 years. Forty six (82.1%) patients were female. The most common disease manifestations were musculoskeletal (87.5%), mucocutaneous (80.3%) and haematological abnormalities (75%). Lupus nephritis was diagnosed in 46.4% of patients and consisted of glomerular ne - phritis in all cases. Neuropsychiatric manifestations occurred in 21.4% but severe central nervous system complications were uncommon, as brain infarcts and organic brain syndrome in 4 (7.1%) patients. Antinuclear antibodies and anti-double stranded DNA were positive in most patients in (98.2% and 71.4% respectively), as well as low C3 and/or C4 were observed frequently (85.7%). Generally, most patients had a good response to therapy as demonstrated by a significant decreasing of SLEDAI score from disease presentation to the last evaluation. The SLEDAI at diagnosis, the maximum SLEDAI and the incidence of complications were significantly higher in patients with neurolupus and/or lupus nephritis. Therapy included oral steroids (87.5%), hydroxychloroquine (85.7%), azathioprine (55.4%), IV cyclophosphamide (28.6%) along with other drugs. Six (10.7%) patients were treated with rituximab. Long-term remission was achieved in 32%, disease was active in 68%, adverse reactions to therapy occurred in 53.6% and complications/severe manifestations in 23.2%. Two patients died, being active disease and severe infection the causes of death. Conclusions: This study suggests that in our patients the clinical and laboratory features observed were similar to juvenile systemic lupus erythematosus patients from other series. Clinical outcome was favourable in the present study. Complications from therapy were frequent.

The Intensive Care Global Study on Severe Acute Respiratory Infection (IC-GLOSSARI): a Multicenter, Multinational, 14-Day Inception Cohort Study

PURPOSE: In this prospective, multicenter, 14-day inception cohort study, we investigated the epidemiology, patterns of infections, and outcome in patients admitted to the intensive care unit (ICU) as a result of severe acute respiratory infections (SARIs). METHODS: All patients admitted to one of 206 participating ICUs during two study weeks, one in November 2013 and the other in January 2014, were screened. SARI was defined as possible, probable, or microbiologically confirmed respiratory tract infection with recent onset dyspnea and/or fever. The primary outcome parameter was in-hospital mortality within 60 days of admission to the ICU. RESULTS: Among the 5550 patients admitted during the study periods, 663 (11.9 %) had SARI. On admission to the ICU, Gram-positive and Gram-negative bacteria were found in 29.6 and 26.2 % of SARI patients but rarely atypical bacteria (1.0 %); viruses were present in 7.7 % of patients. Organ failure occurred in 74.7 % of patients in the ICU, mostly respiratory (53.8 %), cardiovascular (44.5 %), and renal (44.6 %). ICU and in-hospital mortality rates in patients with SARI were 20.2 and 27.2 %, respectively. In multivariable analysis, older age, greater severity scores at ICU admission, and hematologic malignancy or liver disease were independently associated with an increased risk of in-hospital death, whereas influenza vaccination prior to ICU admission and adequate antibiotic administration on ICU admission were associated with a lower risk. CONCLUSIONS: Admission to the ICU for SARI is common and associated with high morbidity and mortality rates. We identified several risk factors for in-hospital death that may be useful for risk stratification in these patients.

Mutational Analysis of Portuguese Families with Multiple Endocrine Neoplasia Type 1 Reveals Large Germline Deletions

OBJECTIVE: To determine the spectrum of MEN1 mutations in Portuguese kindreds, and identify mutation-carriers. PATIENTS, DESIGN AND RESULTS: Six unrelated MEN1 families were studied for MEN1 gene mutations by single-strand conformational polymorphism (SSCP) and DNA sequence analysis of the coding region and exon-intron boundaries of the MEN1 gene. These methods identified 4 different heterozygous mutations in four families: two mutations are novel (mt 1539 delG and mt 655 ims 11 bp) and two have been previously observed (mt 735 del 46p and mt 1656 del C) all resulting in a premature stop codon. In the remaining two families, in whom no mutations or abnormal MEN1 transcripts were detected, segregation studies of the 5' intragenic marker D11S4946 and codon 418 polymorphism in exon 9 revealed two large germline deletions of the MEN1 gene. Southern blot and tumour loss of heterozygosity analysis confirmed and refined the limits of these deletions, which spanned the MEN1 gene at least from: exon 7 to the 3' untranslated region, in one family, and the 5' polymorphic site D11S4946 to exon 9 (obliterating the initiation codon), in the other family. Twenty-six mutant-gene carriers were identified, 6 of which were asymptomatic. CONCLUSIONS: These results emphasize the importance of the detection of MEN1 germline deletions in patients who do not have mutations of the coding region. Important clues indicating the presence of such deletions may be obtained by segregation studies using the intragenic polymorphisms D11S4946 and at codon 418. The detection of these mutations will help in the genetic counselling of clinical management of the MEN1 families in Portugal.
