From Alpha Diversity to Zzz: Interactions among sleep, the brain, and gut microbiota in the first year of life. Prog Neurobiol 2021; 209:102208.

Abstract
Sleep disorders have been linked to alterations of gut microbiota composition in adult humans and animal models, but it is unclear how this link develops. With longitudinal assessments in 162 healthy infants, we present a so far unrecognized sleep-brain-gut interrelationship. First, we report a link between sleep habits and gut microbiota: daytime sleep is associated with bacterial diversity, and nighttime sleep fragmentation and variability link with bacterial maturity and enterotype. Second, we demonstrate a sleep-brain-gut link: bacterial diversity and enterotype are associated with sleep neurophysiology. Third, we show that the sleep-brain-gut link is relevant in development: sleep habits and bacterial markers predict behavioral-developmental outcomes. Our results demonstrate the dynamic interplay between sleep, gut microbiota, and the maturation of brain and behavior during infancy, which aligns with the lately emerging concept of a sleep-brain-gut axis. Importantly, sleep and gut microbiota represent promising health targets since both can be modified non-invasively. As many adult diseases root in early childhood, leveraging protective factors of adequate sleep and age-appropriate gut microbiota in infancy could constitute a health promoting factor across the entire human lifespan.

Treatment Strategy for Unruptured Intracranial Aneurysm in Elderly Patients: Coiling, Clipping, or Conservative? Cell Transplant 2019; 28:767-774.

Abstract
An increasing number of unruptured intracranial aneurysms (UIAs) has been
discovered in elderly patients in recent years, but the optimal treatment
strategy for these patients remains controversial. We report our six-year
experience treating UIAs in elderly patients (≥ 70 years old). A retrospective
review was conducted of elderly patients who harbored UIAs treated by
conservative observation, microsurgical clipping, or endovascular coiling
between January 2009 and December 2014. The patients’ clinical and imaging
information was recorded. Treating methods, procedure-related complications,
imaging results, and clinical outcomes were analyzed. A total of 141 consecutive
elderly patients with 166 UIAs were enrolled in our study. In all, 64 patients
with 79 aneurysms were treated with coiling, and 14 patients with 14 aneurysms
were treated with clipping. The remaining 63 patients with 73 aneurysms were
placed under conservative observation. The average modified Rankin scale was
0.99 (range 0–6) in the full cohort after a mean follow-up of 50.4 months (range
0–70 months). There was no significant difference of modified Rankin scale in
patients with UIAs treated by different methods. Multivariate analysis showed
that age (p=0.030) and aneurysm size (p=0.011)
were independent risk factors for unfavorable outcome of UIAs in the elderly.
Patient age (p=0.010) and aneurysm size
(p=0.020) were also significantly associated with unfavorable
outcome of UIAs managed with observation initially. Our results indicated that
endovascular coil embolization and clipping were both safe and effective
treatment methods for UIAs in the elderly. Aggressive treatment for UIAs in
elderly patients with risk factors of aneurysm rupture should be considered
positively.

Abstract
To analyze the size and location distribution of ruptured intracranial aneurysms (IAs) helps to provide evidence for clinical treatment of unruptured IAs using this feature of aneurysms. In this study, 415 patients who presented with an acute subarachnoid hemorrhage caused by IAs were enrolled from eight tertiary referral centers between June 2016 and March 2018. The size, aspect ratio and anatomic location of ruptured IAs were defined and reported by patient sex. In the study cohort of 415 patients (60.5% women) with saccular ruptured IAs, the three most common locations of ruptured IAs were posterior communicating artery (32.0%), anterior communicating artery (28.7%), and middle cerebral artery (13.5%). The mean size of all ruptured IAs was 5.3±3.1 mm (range 1.1-28.5 mm), but the size varied considerably by location. For example, ruptured IAs of the posterior communicating artery had a mean size of 5.8±3.1 mm, whereas the mean size of ruptured anterior communicating artery aneurysms was 4.6±1.7 mm. The mean AR in all ruptured IAs was 1.66±0.76. Of those aneurysms, 243 (58.6%) had an AR smaller than 1.6 and 318 (76.6%) had an AR smaller than 2.0. Our results suggested that the size of the most ruptured IAs are smaller than 7 mm or even 5 mm. The size and AR varied by sex and location. With the knowledge of size, location and AR, multiplicity should be considered for treatment strategies of unruptured IAs.

Abstract
BACKGROUND AND PURPOSE Although flow diverters have been reported with favorable clinical and angiographic outcomes in various literatures, randomized trials determining their true effectiveness and safety are still in lack. The Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter (PARAT) trial was designed to evaluate the safety and efficacy of the Tubridge flow diverter in the treatment of large or giant aneurysms in comparison with Enterprise stent-assisted coiling. MATERIALS AND METHODS This prospective, multicenter, randomized trial was conducted at 12 hospitals throughout China. Enrolled adults with unruptured large/giant intracranial aneurysms were randomly assigned (1:1) to receive either Enterprise stent-assisted coiling or Tubridge flow diverter implantation. The primary end point was complete occlusion at 6-month follow-up, while secondary end points included technical success, mortality, target vessel-related stroke, aneurysm bleeding, in-stent stenosis, parent artery occlusion, and the frequency of all adverse events. RESULTS Among 185 enrolled subjects, 41 withdrew before procedure initiation. Overall, 82 subjects underwent Tubridge implantation, and 62 subjects were primarily treated with stent-assisted coiling. The results of 6-month follow-up imaging included complete occlusion rates of 75.34% versus 24.53% for the Tubridge and stent-assisted coiling groups, respectively, with a calculated common odds ratio of 9.4 (95% confidence interval, 4.14-21.38; P < .001). There was a higher, nonsignificant frequency of complications for Tubridge subjects. Multivariate analysis showed a decreased stroke rate at the primary investigational site, with a marginal P value (P = .051). CONCLUSIONS This trial showed an obviously higher rate of large and giant aneurysm obliteration with the Tubridge FD over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications. Investigational site comparisons suggested that a learning curve for flow-diverter implantation should be recognized and factored into trial designs.

Abstract
A 26-year-old man presented with symptoms of progressive bilateral exophthalmos and swelling of the eyelids after a severe head injury. Angiography confirmed a direct carotid-superior hypophyseal arterial (SHA) cavernous fistula with petrosal sinus and intracavernous sinus drainage. Successful transarterial coil embolization of the fistula was performed with resolution of the patient's symptoms. To our knowledge, post-traumatic arteriovenous fistula between SHA and the cavernous sinus has not been previously reported. We hereby demonstrate an effective, minimally invasive method of occluding a rare fistula by transarterial embolization.

Abstract
INTRODUCTION Primary non-Hodgkin's lymphoma of the nasal cavity is particular. Pathological characteristics mainly associate a prevalent NK lymphocyte phenotype, a frequent exposure to the Epstein-Barr virus and a poor sensitivity to radiotherapy compared to other lymph node localizations. EXEGESIS The authors report the case of a 38-year-old man. The patient had previously presented a chronic maxillary sinusitis. After a diagnosis of Wegener's disease, the poor course under therapy resulted in a nasal lymphoma. Natural killer cell nasal lymphoma was confirmed with a leading biopsy at the same time as a serious clinical outcome. The patient died of septic shock with multivisceral failure. CONCLUSION The two differential diagnoses of ulcerative lymphoma of the midface are ulcerative infectious diseases and Wegener's disease. We must not miss this severe disease, with its poor prognosis and variable, though sometimes rapid speed of evolution.

Abstract
INTRODUCTION The association between dermatomyositis and cancer is clearly established, but its frequency remains difficult to define. EXEGESIS We report the case of an association between a dermatomyositis and a cancer of the piriform antrum. Four months after surgical treatment and radiotherapy, the increased macro-CK level gave us reason to suspect a cancer relapse with pulmonary, hepatic, splenic and renal metastases without progressive clinical signs. CONCLUSION Mitochondrial macro-CK detection must evoke the presence of neoplasia with or without metastasis, which would be a poor prognosis, as has been shown in our patient.

Abstract
OBJECTIVE Eosinophilic fasciitis (EF) is a scleroderma-like disease of unknown etiology characterized by skin induration, elevated immune globulins, and peripheral eosinophilia. The hallmarks of the chronic cutaneous involvement in this syndrome are inflammation and fibrosis of the fascia. To determine how the inflammatory process in EF may be regulated, we investigated the spontaneous and mitogen induced [lipopolysaccharide (LPS), phytohemagglutinin (PHA) or both LPS+PHA] syntheses of interleukins (IL)-2, 5 and 10, interferon-gamma (IFN-gamma), and leukemia inhibitory factor (LIF) cytokines by peripheral blood mononuclear cells (PBMC) from 4 patients with active EF and compared them to those of 10 healthy individuals. METHODS We used a short term whole blood assay and culture supernatants were collected after 24 h to measure the IL-2 and IFN-gamma contents and after 48 h to evaluate IL-5, IL-10, and LIF. Supernatant cytokine concentrations were determined by ELISA. RESULTS All 4 patients had similar patterns of cytokine secretion. Cytokine production did not differ between patients and controls under basal conditions or when LPS was added to the cultures. In contrast, under PHA or LPS+PHA stimulation, significantly higher amounts of all 5 cytokines were detected in samples from patients compared to those from controls. CONCLUSION Overall, our data suggest that EF is characterized by an increased capacity of PBMC to produce IL-5 and IL-10, possibly leading to eosinophilia and immune globulin overexpression. In this context, the simultaneous elevations of type 1 cytokines (IL-2 and IFN-gamma) and LIF production by the same cells may be an attempt by the immune system to limit the exacerbation of a type 2 dominant response.

Abstract
Cryoglobulinaemia in association with Waldenström's macroglobulinaemia is relatively common, ranging from 8% to 18% of cases; however, < 5% have symptoms or complications. We describe a patient with a history of cutaneous, peritoneal, and fallopian tube vasculitis related to type II cryoglobulinaemia associated with Waldenström's macroglobulinaemia. Cytotoxic treatment was initiated (cyclophosphamide, vincristine, and prednisone) and had a good initial response. However, after the third course of chemotherapy, the patient presented with septic shock and died. Even though cryoglobulinaemia is a model of systemic vasculitis, peritoneal and fallopian tube vasculitis associated with type II cryoglobulinemia has not been described previously.

Abstract
Background: Cases of lipodystrophy syndrome and metabolic disorders have been described since the onset of highly active antiretroviral therapy in HIV-infected patients. The aim of our study was to estimate the prevalence of lipodystrophy (LD) and to define the associated lipid profile of these patients. Methods: The following were determined for each patient: lipid profile (cholesterol and its subfractions, atherogenicity ratios, and triglycerides), blood glucose, and immunovirological markers (CD4(+) cell count and plasma viral load). Patients were classified into two groups on the basis of whether or not they presented with clinical signs of LD. Results: Among 233 HIV-infected patients included in the study, 61 cases (26.1%) of lipodystrophy (LD) were noted. Compared with non-LD patients (NLD), LD patients were older men (P<10(-4)) with a lower CD4(+) lymphocyte cell count (P<0.007) and more often at the AIDS stage (P<10(-3)) (OR=3.2 (95% CI: 1.47-6.2)). Multivariate analysis showed a correlation between LD cases and age (10 years older) (OR=1.78 (95% CI: 1.23-2.57), P<0.002) and the decrease in CD4(+) cell count (100 CD4(+)/mm(3) lower) (OR=1.31 (95% CI: 1.09-1.58), P<0.004). An analysis of lipid subfractions and atherogenicity ratios clearly indicated a proatherogenic lipid profile for the LD patients. Conclusions: The underlying physiopathological mechanism of LD is still unknown. However, the lipid profile of HIV-1-infected patients with a LD syndrome appears to place these patients at an increased risk of progression of atherosclerosis.

Abstract
INTRODUCTION Pancreatic cancer is responsible for 6,000 deaths per year in France. During the course of the disease, venous thrombosis is common. Conversely, arterial thrombosis is rarely described. EXEGESIS We report the case of a 59-year-old patient with pancreatic adenocarcinoma. Treatment by gemcitabine allowed rapid and persistent improvement of the body weight and a prolonged survival (18 months). Sudden complication, i.e. splenic arterial thrombosis, reversed the favorable outcome. CONCLUSION Splenic venous thrombosis is a frequent complication occurring in the course of pancreatic cancer. It is easily diagnosed using abdominal computerized tomography. Arterial thrombosis is rarely observed. It might be due to either sporadic, unexpected, occurrence of cases related to the evolution of underlying pathological mechanisms, or to omitted treatment of vascular complications, as until the introduction of new anticancer drugs this disease was considered to be of very poor prognosis.

Abstract
We describe the case of a teenager who developed fever, arthritis, cutaneous vasculitis and severe pancytopenia 3 weeks after the third vaccination boost with a recombinant hepatitis B vaccine. Bone marrow examination showed paucity of late myeloid elements and, subsequently, maturation arrest. Interferon-gamma (IFN-gamma) production by peripheral blood mononuclear cells from the patient was dramatically increased. An underlying immune predisposition (HLA-DR3) may have indirectly enabled the vaccine to trigger a hepatitis B virus-specific cytotoxic T-lymphocyte response. It is therefore possible that the pancytopenia was induced by a dysregulation of the CD8+ T-cell compartment via increased IFN-gamma production.

Abstract
Chronic hepatitis C virus (HCV) infection may be associated with numerous immune disorders, with vasculitis including polyarteritis nodosa, or with both. Cryoglobulinemia, which is often present, can also be expressed by vasculitis. We describe 2 cases of Churg-Strauss syndrome (CSS) in patients with HCV infection. We found no previous case of CSS accompanying HCV infection in the literature. The current patients were women aged 40 and 66 years. In both cases, a clinical and laboratory pattern suggesting CSS was found before the HCV infection was discovered. One patient had cryoglobulinemia. One patient was successfully treated with interferon (IFN). The other was treated for 18 months with IFN and corticosteroids. Second-line therapy consisting of IFN with ribavirin was successful. The emergence of HCV infection may have led to an induced form of CSS. The relationship among HCV, cryoglobulinemia, and CSS is not clear, but may be similar to that existing between polyarteritis nodosa and hepatitis B virus. These observations suggest that IFN-alpha therapy may be effective against CSS in HCV infected patients with or without cryoglobulinemia.

Abstract
We describe a 58-year old patient with chronic lymphocytic leukemia (CLL) who developed systemic lupus erythematosus (SLE) with severe joint involvement. Dilated myocardiopathy precluded the use of high corticoid doses and a 15 days of prednisone (15mg/d) had no effect on the polyarthritis. Therefore, fludarabine (25mg/m2) was administered for 5 d. One month after the first cycle, fever, muscle stiffness and polyarthritis resolved. A total of 6 cycles were administered. The evolution was complicated by herpes zoster infection and left pneumococcal pneumonia. At this time of writing (July 1999), the patient is symptom free but is profoundly lymphopenic.

Abstract
INTRODUCTION The acrodystrophic neuropathy described by Bureau and Barrière in the 1950s is a rare trophic complication of chronic, analgesic neuropathy due to alcohol abuse, which is at the origin of perforating ulcers of the foot, vasomotor disorders with dysautonomia, and leads to mutilating arthropathy of the lower limb. This neuroacropathy, also termed vagabonds' or vagrants' disease, usually occurs in subjects with a debilitated condition, chronic alcoholism, and unfavourable socioeconomic conditions. EXEGESIS We report four cases of Bureau-Barrière disease which occurred in male subjects who were on average 55 years of age. The clinical presentation was close to that reported in the literature. Indeed, all four patients were alcoholic, nondiabetic and lived under conditions of precarious hygiene. Therapeutic management of the patients was difficult due to bad compliance with the treatment and persistence of alcohol abuse. Immobilization of the foot is considered to be the primary treatment. Local care including baths and bandages with hydrocolloids must be continued during several months, and associated with antibiotic therapy, administered by infusion when necessary. The outcome is often chronic, with poor prognosis. Given the limited therapeutic possibilities, acrodystrophic neuropathy is an invalidating disease with high morbidity. CONCLUSION Bureau-Barrière disease is a rare, serious invalidating disease. The clinical symptomatology is usually based on the diagnostic triad: analgesia of the foot, perforating ulcers of the foot, and deforming and mutilating arthropathy of the lower limb. Treatment is often hampered due to poor compliance with local care and persistence of alcohol abuse.

INTRODUCTION Parotidean and ovarian lymphoma often indicate the existence of non-Hodgkin's lymphoma, involving 1-5% and 0.2% of the cases, respectively. EXEGENESIS: The authors report the case of a 70-year-old woman who presented B cell lymphoma of the parotid gland revealed by a rapid increase in the parotid size. CT scan showed the existence of a tumor located in the left ovary, later confirmed by biopsy. The proposed diagnosis was diffuse B cell type lymphoma with double glandular localization. Adenopathy and bone marrow involvement were both lacking. CONCLUSION Lymphoma with glandular localizations always require diagnosis confirmation via histological examination and immunophenotyping, and must be considered as the local sign of a general disease.

Abstract
This review is aimed at defining the frequency, the clinical, biological and radiological presentation and the therapeutic possibilities for AL amyloid arthropathies. The frequency of AL amyloid arthropathy is estimated to be between 2 and 5%. There is usually a bilaterally progressive symmetrical arthritis of multiple joints (predominantly in the upper limb joints) with a chronic evolution. Neurologic or cutaneous symptoms are common. The analysis of synovial fluid sediments is a key test for the diagnosis of amyloid arthropathy. Patients with amyloid arthropathy must be screened for monoclonal gammapathies. The synovectomy is the best symptomatic treatment. A better knowledge of the pathogenesis of amyloid deposits should permit to improve therapeutical strategies.

Abstract
Neuropsychiatric forms of systemic lupus erythematosus (SLE) vary, most commonly consisting of seizures, psychiatric disturbances, or focal central nervous deficits. This is a new case of neuromyelitis optica or Devic's syndrome during the course of SLE. Few reports of this association exist in the literature. Our objective is to report this unique case of Devic's neuromyelitis optica during pregnancy in a patient with systemic lupus erythematosus. A 28-year-old woman had been diagnosed as having SLE with cutaneous and articular involvement in 1987 when she was 17 years old. She was treated with a synthetic antimalarial agent associated with corticosteroids. In 1994, during the fourth month of pregnancy, she had signs of transverse myelitis with a sensory level at T6 associated with an optic neuropathy suggesting a Devic's syndrome. The patient was managed by plasmapheresis sessions and intravenous corticosteroids. Transverse myelitis recurred postpartum and three years later at the same thoracic level. Management by bolus administration of a steroid and cyclophosphamide resulted in remission again. There have only been around a dozen reports in the literature of patients who had both Devic's neuromyelitis optica and SLE. Magnetic resonance imaging is contributive to diagnosis and therapeutic follow-up, showing spinal cord lesions with increased intensity on T2-weighted sequences. Although the clinical course of the present patient has been favourable so far, the prognosis of this neurologic disease is generally considered to be poor with elevated mortality.

Abstract
Acquired von Willebrand disease associated with systemic lupus erythematosus (SLE) has been detected in three middle-aged women. In each case the first clinical manifestation was a bleeding syndrome. Plasma levels of von Willebrand factor (VWF) and ristocetin-induced platelet agglutination were as found in type 1 von Willebrand disease for the first patient, type 3 for the second patient, and type 2 for the third patient. Intraplatelet levels of VWF were normal for all three patients. In all cases a mixture of patient's plasma with normal plasma resulted in inhibition of ristocetin-induced binding of VWF to normal platelets. Intravenous immunoglobulin given to patients 2 and 3 corrected the plasma VWF level of the second patient but not that of the third. Therapy with corticosteroids was partially beneficial for patient 3 and patient 2. For patient 2, the severity of the cutaneous lesions also led to the use of cyclophosphamide, and this therapy resulted in total correction of VWF levels. Our observations confirm previous reports of acquired von Willebrand syndrome associated with SLE and show heterogeneity both in the phenotypic form and in the response to treatment.

Abstract
INTRODUCTION Hodgkin's disease can be associated with various non-specific cutaneous manifestations. EXEGESIS We report two cases of Hodgkin's disease revealed by erythema nodosum and cutaneous vasculitis. CONCLUSION Although pathogenesis of this unusual association is unknown, lymphoma should be suspected in patients presenting with vasculitis and/or erythema nodosum.

Abstract
We investigated the production of IL-2, IFN-gamma, IL-10 and IL-4 by PBMC from 24 patients with SLE and 10 healthy individuals. Basal and mitogen-stimulated (lipopolysaccharide and phytohaemagglutinin (LPS + PHA)) cytokine production was determined in a whole blood assay (WBA). Supernatants were collected and assayed with specific ELISAs. Although the IL-2 and IFN-gamma contents did not differ significantly between patients and controls under both conditions, statistically significant correlations were found between each cytokine and disease activity (SLAM index) after stimulation (respectively, r = 0.501, P = 0.01 and r = 0.631, P = 0.001). PBMC IL-10 production was significantly higher for patients than controls (P = 0.05), but no correlation between IL-10 levels and the SLAM index was obtained. IL-4 production was not statistically different between SLE patients and controls. For stimulated WBAs, the IL-10/IL-2 and IL-10/IFN-gamma ratios were significantly correlated with disease severity (P = 0.02; P = 0.001, respectively). Overall, our data suggest that SLE is characterized by an elevated production of IL-10, reflecting the basal state of activation of the immune system. During exacerbation of SLE, IL-2 and IFN-gamma are synthesized in larger amounts and may cause the tissue damage observed.

Abstract
Protein-losing enteropathy (PLE) is characterized by loss of essentially protein substances into the gastrointestinal tract. Few reports of PLE supervening in patients who have systemic lupus erythematosus (SLE) have appeared in the literature. We report three new cases. All three were women who had a severe form of SLE involving several organs. PLE was diagnosed on the basis of an increased clearance of alpha 1 antitrypsin. The severeness of the clinical picture in all three patients justified the use of immunosuppressive agents (corticosteroids and pulse cyclophosphamide therapy) which were effective. These cases are compared to the 24 previously reported. The frequency of PLE during an SLE flare-up is probably underestimated. It should be looked for in SLE patients who have edema by means of the simple alpha 1 antitrypsin test. PLE is often found in severe clinical forms of SLE and should be managed using corticosteroids either alone or in association with immunosuppressive drugs.

Abstract
BACKGROUND The precise diagnostic criteria for paraneoplastic pemphigus defined by Anhalt are not always present. In many cases, the clinical and histological features are misleading. CASE REPORT We observed a case of paraneoplastic pemphigus in a 60-year-old man followed for low-grade inactive nodal lymphoma. The clinical course was long. The main features were lichenoid cutaneous and mucosal lesions without bullae. The only histology finding was basal vacuolization, lymphocyte infiltration and suspended keratinocyte necrosis without acantholysis. This clinical and pathological situation continued for one year. Just a few days prior to the patient's death, the clinical situation suddenly worsened with major bullae involving most of the skin surface and mucosal areas including the esophagus and respiratory tract. Cyclosporine and bolus injections of corticosteroids did not prevent the fatal outcome. DISCUSSION This unusual lichenoid presentation has not been previously described. Associated skin erosions usually occur early in the disease course. The long lichenoid presentation for several months without acantholysis emphasizes the difficulties encountered in the diagnosis of paraneoplastic pemphigus. This diagnosis should be entertained in cancer patients who develop lichenoid lesions.

Abstract
We report a series of seven patients who had scleroderma renal crisis. Their primary clinical and laboratory features along with the details of their management were compared with those of similar cases from the literature. The seven patients died within one to four months of the diagnosis with a pattern of acute renal failure, left ventricular failure and malignant hypertension. Histopathologic examination was performed in four of the patients, in two of whom it revealed thickening of the wall of the interlobular arteries related to the scleroderma, and in the other two patients nonspecific lesions of malignant hypertension. This histopathologic particularity led us to propose, on the basis of multiple renal biopsies performed in patients with scleroderma, a lesion chronology of the kidney in patients with scleroderma. Nevertheless, the triggering factors and pathophysiologic mechanisms of scleroderma renal crisis remain unclear and its prognosis is severe. Early treatment with angiotensin-converting enzyme inhibitors and other vasodilatators administered intravenously can prevent death and dialysis.
