Understanding the Interplay Between Premenstrual Dysphoric Disorder (PMDD) and Female Sexual Dysfunction (FSD).

Premenstrual dysphoric disorder (PMDD) is a severe variant of premenstrual syndrome (PMS), categorized as a mood disorder due to marked symptoms of depression and anxiety, compounded with severe physical symptoms. Female sexual dysfunction (FSD) can manifest as low libido, difficulty achieving sexual pleasure, and dyspareunia, causing functional and psychological distress. PMDD and FSD are globally prevalent conditions with postulated biological, psychological, and social associations between them. Nevertheless, sexual dysfunction in PMDD is an important aspect of women's health that has been understudied and has notable methodological limitations. In this narrative review, we summarize the existing literature on sexual function in women with PMDD and PMS, specify the distinctions between PMDD and other general symptoms of PMS, highlight the significance of understanding sexual dysfunction in the female population, and outline some available therapeutic options. Studies show that women frequently experience debilitating sexual distress during the premenstrual phase; however, there is an essential need to formulate standardized tools for definite diagnosis. Selective serotonin re-uptake inhibitors (SSRIs) and combined oral contraceptive pills (COCPs) are approved medications for PMDD, while flibanserin and bremelanotide are effective in treating FSD. However, the potential effects of these treatment modalities on the two comorbid conditions render them inconclusive. Awareness of PMDD and FSD among clinicians and society can allow the implementation of targeted interventions to alleviate the suffering of women and enhance their quality of life.

Virtual reality modelling for planning of percutaneous first step palliation in a newborn with heterotaxy syndrome.

We report the first-stage percutaneous palliation in a newborn with a rare heterotaxy syndrome variant including interrupted inferior vena cava, partial anomalous pulmonary venous drainage, and restrictive interatrial communication. Virtual reality imaging aided visualisation, decision-making, and planning. Successful atrial septoplasty performed via the internal jugular vein and anomalous pulmonary vein was followed by stenting of ductus arteriosus.

#1012 Lifetime risk of autosomal recessive kidney diseases calculated from genetic databases

Abstract Background and Aims Genetic kidney diseases represent an often rare and clinically diverse group. Their distinct clinical and genetic variations and biases in patient referrals and identification pose challenges in phenotype-based estimated prevalences. This study aimed to determine the calculated lifetime risk of autosomal recessive kidney diseases. Method We conducted a thorough literature review to compile a list of 149 genes linked to these diseases. Disease-causing variants were collected from ClinVar, HGMD, LOVD, and our database and reevaluated according to current guidelines. Minor allele frequencies were obtained from gnomAD and our database. We estimated the lifetime risk of autosomal recessive kidney diseases in a dataset of 12,800 disease-causing variants across 149 disease-associated genes (31 glomerulopathy, 16 tubulopathy, 87 ciliopathy, and 15 CAKUT genes). Results The combined estimated lifetime risk is 10.68 per 100,000 (95% confidence interval 6.29-18.40) based on our data and 22.77 per 100,000 (15.86-33.77) using the European gnomAD dataset. Notably, the three disorders with the highest lifetime risk (≥1.2 per 100,000), collectively accounting for 28% of the overall lifetime risk, were caused by PKHD1 (autosomal recessive polycystic kidney disease), SLC12A3 (Gitelman syndrome), and COL4A3 (Alport syndrome) variants (Fig. 1). Extrapolation to all modes of inheritance, the overall lifetime risk for monogenic kidney disease in adults ranged from 1 in 602 to 1 in 1,283 (Fig. 2). Conclusion This study provides a population-genetic estimate of lifetime risk for autosomal recessive kidney diseases across different populations, addressing underestimated prevalences and diagnostic probabilities. The data, therefore, informs resource allocation for therapy development, public health management, and biomedical research.

Venous anomalies: an underrecognized but important cause of venous thromboembolism

AbstractAnatomical variants, such as May-Thurner syndrome (MTS) and inferior vena cava (IVC) variants, are underrecognized causes of deep venous thrombosis (DVT), despite affecting management. We aimed to identify the proportion of anatomical variants in proximal lower limb DVT. A retrospective cohort study was performed with cases of acute proximal DVT from 2014 to 2021 identified from ICD-10 codes. We identified 4731 DVTs and included 1268 proximal DVTs. Thirty-six (2.84%) had an anatomical variant (25 MTS and 11 IVC variants), with a rate of 14.39% in females <50 years old. Compared with nonvariant DVTs, they were more likely to be unprovoked (81% vs 23%), younger (median age, 37 vs 63 years), female (67% vs 37%), and have postthrombotic syndrome (22% vs 9%). Variants frequently received thrombolysis (58% vs 1%) or angioplasty (47% vs 0%) and indefinite anticoagulation (83% vs 40%). Further investigation for variants should be considered for high-risk patients, as variants affect management.

Functional studies in yeast confirm the pathogenicity of a new GINS3 Meier-Gorlin syndrome variant.

Meier-Gorlin syndrome (MGORS) is an autosomal recessive disorder characterized by short stature, microtia, and patellar hypoplasia, and is caused by pathogenic variants of cellular factors involved in the initiation of DNA replication. We previously reported that biallelic variants in GINS3 leading to amino acid changes at position 24 (p.Asp24) cause MGORS. Here, we describe the phenotype of a new individual homozygous for the Asp24Asn variant. We also report the clinical characteristics of an individual harboring a novel homozygous GINS3 variant (Ile25Phe) and features suggestive of MGORS. Modification of the corresponding residue in yeast Psf3 (Val9Phe) compromised S phase progression compared to a humanized Psf3 Val9Ile variant. Expression of Psf3 Val9Phe in yeast also caused sensitivity to elevated temperature and the replicative stress-inducing drug hydroxyurea, confirming partial loss of function of this variant in vivo and allowing us to upgrade the classification of this variant. Taken together, these data validate the critical importance of the GINS DNA replication complex in the molecular etiology of MGORS.

Suspected duloxetine-induced restless legs syndrome phenotypic variant: a case report

BackgroundRestless arms syndrome (RAS) is the most common variant of restless legs syndrome (RLS), which is easy to be ignored in clinical practice due to the lack of specific diagnostic criteria. When effective therapeutic agents induced RAS and symptoms persisted after briefly observation, clinicians will face the challenge of weighing efficacy against side effects.Case presentationA 67-year-old woman was admitted to a geriatric psychiatric ward with depression. Upon admission, the escitalopram dose was reduced from 15 mg to 10 mg per day, and the duloxetine dose was increased from 60 mg to 80 mg per day. The next night before bedtime, she developed itching and creeping sensations deep inside bilateral shoulders and arms, with the urge to move, worsening at rest, and alleviation after hammering. The symptoms persisted when escitalopram was discontinued. A history of RLS was confirmed. Treatment with 40 mg of duloxetine and 0.125 mg of pramipexole significantly improved depression, and the paresthesia disappeared, with no recurrence occurring 6 months after discharge.Discussion and conclusionsThis case suggests that psychiatrists should pay attention to RLS variants when increasing doses of duloxetine. Long-term improvement can be achieved through dosage reduction combined with dopaminergic drugs instead of immediate discontinuation.

Ischemic stroke due to stylocarotid artery syndrome: a case report and review.

Stylocarotid artery syndrome (SAS) is a rare variant of Eagle's syndrome that may lead to transient ischemic attack or stroke. The underlying pathophysiological mechanism involves compression of the internal carotid artery by an elongated styloid process (ESP), potentially resulting in vascular occlusion or dissection. An ESP exceeding 2.5 cm is deemed elongated, with a length of 3.0 cm considered clinically significant. Although the prevalence of ESP ranges from 4.0% to 7.3%, symptomatic cases are rare; symptoms are present in only approximately 4.0% of individuals with an ESP. Unlike the typical symptoms of Eagle's syndrome, SAS may not cause pharyngeal discomfort, the sensation of a foreign body in the throat, dysphagia, or facial pain. This absence of characteristic symptoms as well as the development of central nervous system symptoms often leads patients to seek care from neurologists instead of otolaryngologists, increasing the likelihood of misdiagnosis or underdiagnosis. We herein report a unique case of ischemic stroke caused by SAS and present a literature review on cases of SAS-associated ischemic stroke published in the past decade. The reporting of this study conforms to the CARE guidelines.

СЛУЧАЙ ИЗ ПРАКТИКИ: ЭПИЗОДИЧЕСКАЯ ПАРОКСИЗМАЛЬНАЯ МОЗЖЕЧКОВАЯ АТАКСИЯ 2 ТИПА

Instability walking is a fairly common complaint made by patients who come to be examined by a neurologist in polyclinics and hospitals. From a medical point of view, this symptom is included in the concept of "ataxia". Neurologists distinguish four types of ataxia depending on the localization of the pathological process: cortical, cerebellar, vestibular, and sensitive. There are often combinations of different types of ataxia in the same patient, for example, cortical-vestibular, sensitive-cerebellar. In addition to establishing the variant of the atactic syndrome, there is an urgent question of verifying the etiological factor that led to this pathology. Pathological heredity becomes the least obvious. In this article, we draw attention to a similar case from practice in order to form the alertness of doctors regarding hereditary coordination disorders. Episodic ataxia is a group of rare hereditary diseases of the nervous system, the main clinical manifestation of which are paroxysms of cerebellar ataxia of varying duration and frequency. The most studied from a genetic and clinical point of view are episodic cerebellar ataxia of the first and second types. The authors present a clinical case of episodic paroxysmal cerebellar ataxia type 2 in a 22-year-old patient. The diagnosis of the disease was based on a typical clinical picture and confirmed by a molecular genetic study that revealed a mutation in the CACNA1A gene. The article discusses aspects of the pathogenesis of the main forms of episodic paroxysmal ataxia, age of onset, frequency and duration of seizures, features of the clinical picture, neurological status. This clinical observation draws the attention of practitioners to the possibilities of modern methods of molecular genetic diagnosis and treatment of these conditions.

Neurogenic Bladder: A Rare Autonomic Sign in a Patient With Preserved Speech Variant (Zappella Variant) Rett Syndrome

Background: Rett syndrome is characterized by the loss of speech and purposeful hand movements, ambulation problems, and typical hand stereotypies. Preserved speech variant Rett syndrome (Zappella Variant) is a much less common form where speech is relatively preserved, from words to simple sentences. Lower urinary tract dysfunction and neurogenic bladder due to autonomic involvement have been only rarely reported in Rett syndrome. We aimed to emphasize neurogenic bladder due to autonomic dysfunction, which has very rarely been reported in the literature, in a patient with preserved speech variant Rett syndrome, a rare form of the Rett syndrome. Case presentation: A 7-year-old female patient who had been diagnosed with severe vesicoureteral reflux and neurogenic bladder when 11 months old due to the inability to urinate was suspected of suffering from Rett syndrome after intense eye contact and the stereotypic movement of hand wringing were observed. The patient could talk with phrases and walk and had purposeful hand movements. The presence of the c.961C&amp;gt;T (p.Arg321Trp) mutation in the C terminal region of the MECP2 gene was demonstrated with Sanger sequencing. The patient is currently 13 years old and is receiving special education and continues to be monitored for chronic renal disease at the pediatric nephrology department. Conclusion: The presence of hand stereotypies and intense eye pointing could indicate the Zappella variant Rett syndrome in a female patient who has developmental problems, can talk, has purposeful hand skills. Rett syndrome patients can also have lower urinary tract dysfunction although this is less common than cardiac, respiratory and gastrointestinal autonomic involvement. The development of intermittent urinary retention and vesicoureteral reflux may be associated with neurogenic bladder caused by autonomic involvement should be considered in these patients and one must be aware of the complications.

Neutrophilic Dermatosis of the Dorsal Hands

Neutrophilic dermatosis of the dorsal hands (NDDH) is a localized variant of Sweet syndrome, a neutrophilic dermatosis commonly associated with underlying malignancy or systemic inflammatory disorders. NDDH can be mistaken for infection due to its rarity, clinical appearance, and common association with elevated inflammatory markers. A high index of suspicion for this diagnosis should be maintained with symmetrical hand lesions, as approximately 78% of patients with NDDH have bilateral disease. Patients respond rapidly to the initiation of systemic steroids; however, like with generalized cutaneous Sweet syndrome, diagnosis should prompt further work-up for underlying disease.

Restless legs syndrome variants: A systematic review

IntroductionRestless Legs Syndrome (RLS) is a clinical syndrome that may manifest itself in non-leg parts of the body as well, called RLS variant, which is considered a distinct entity by some researchers. In this systematic review, we tried to evaluate various clinical features and effective treatments of RLS variants and compare them with that of typical RLS. MethodsThis study was conducted following the PRISMA guideline. The primary search was performed in the data resources of Medline (PubMed), Web of Science, and Scopus, as well as the Google Scholar search engine. The required data were extracted from the studies. ResultsIn this review, 1565 studies were initially identified and finally 39 studies were selected. The most common RLS variants were observed to involve hands, head, abdomen, and genitalia. These patients mostly complained of sleep disturbance and feelings of itching, tingling and twitching. Supportive diagnostic criteria of RLS including familial history of RLS, periodic limb movements during sleep (PLMS) and response to treatment with dopaminergic agents were assessed. ConclusionIt seems that patients with RLS variant can undergo the same diagnostic and therapeutic work-up as patients with conventional RLS. It is suggested that these two disorders fall into the same syndromic spectrum.

Eosinophilic Myocarditis: From Bench to Bedside.

Myocarditis is a polymorphic and potentially life-threatening disease characterized by a large variability in clinical presentation and prognosis. Within the broad spectrum of etiology, eosinophilic myocarditis represents a rare condition characterized by eosinophilic infiltration of the myocardium, usually associated with peripheral eosinophilia. Albeit uncommon, eosinophilic myocarditis could be potentially life-threatening, ranging from mild asymptomatic disease to multifocal widespread infiltrates associated with myocardial necrosis, thrombotic complications, and endomyocardial fibrosis. Moreover, it could progress to dilated cardiomyopathy, resulting in a poor prognosis. The leading causes of eosinophilic myocarditis are hypersensitivity reactions, eosinophilic granulomatosis with polyangiitis, cancer, hyper-eosinophilic syndrome variants, and infections. A thorough evaluation and accurate diagnosis are crucial to identifying the underlying cause and defining the appropriate therapeutic strategy. On these bases, this comprehensive review aims to summarize the current knowledge on eosinophilic myocarditis, providing a schematic and practical approach to diagnosing, evaluating, and treating eosinophilic myocarditis.

Zinner syndrome: A rarer variant of a rare syndrome

Zinner syndrome, characterized by the combination of absent unilateral kidney, obstructed ejaculatory duct on the same side, and cysts in the seminal vesicle, represents a rare congenital malformation of the mesonephric duct. Its symptoms are often vague, ranging from urinary discomfort to painful ejaculation and infertility, making it difficult to diagnose without imaging. In this report, we discuss a less common form of Zinner syndrome identified through diagnostic imaging.

Crouzon syndrome: features of clinical manifestations, management and outcomes in children

Syndromic craniosynostosis is a special group of hereditary pathologies. One of the syndromic craniosynostoses is Crouzon syndrome, an autosomal dominant pathology of the primary violation of the fusion of cranial sutures. It occurs with a frequency of 1:60,000 newborns. The disease leads to a number of secondary complications, such as exophthalmos, orthognathic problems, impaired vision, hearing, breathing, lag in neuropsychic development. The development of Crouzon syndrome is associated with a missense mutation in the fibroblast growth factor receptor-2 (FGFR2) gene. In modern medicine, a variant of Crouzon syndrome with black acanthosis is also known, the development of which is associated with a mutation in the FGFR3 gene. The similarity of clinical manifestations as with others syndromic craniosynostoses, also between 2 variants of Crouzon syndrome, leads to difficulties in differential diagnostic search. Knowledge and awareness of the full clinical presentation of this syndrome makes it possible to timely diagnose and treat, prevent possible severe complications and improve the quality of life of patients with Crouzon syndrome. This article describes 2 clinical cases with mutations in the FGFR2 and FGFR3 genes.

Hypoplastic Left Heart Syndrome with Mitral Stenosis and Aortic Atresia—Echocardiographic Findings and Early Outcomes

Mitral stenosis/aortic atresia (MS/AA) has been reported as a high-risk variant of hypoplastic left heart syndrome (HLHS), potentially related to ventriculocoronary connections (VCCs) or endocardial fibroelastosis (EFE) and myocardial hypoperfusion. We aimed to identify echocardiographic and clinical factors associated with early death or transplant in this group. Patients with HLHS MS/AA treated at our center between 2000 and 2020 were included. Pre-stage I palliation echocardiograms were reviewed. Certain imaging factors, such as determination of VCC, EFE, and measurement of tricuspid annular plane systolic excursion were measured from retrospective review of preoperative images; others were derived from clinical reports. Groups were compared according to primary outcome of death or transplant prior to stage II palliation. Of 141 patients included, 39 (27.7%) experienced a primary outcome. Ventriculocoronary connections were identified in 103 (73.0%) patients and EFE in 95 (67.4%) patients. Among imaging variables, smaller ascending aorta size (median, 2.2 [interquartile range (IQR) 1.7-2.8] vs 2.6 [2.2-3.4] mm, P=.01) was associated with primary outcome. There was similar frequency of VCC (74.4% vs 72.5%, P=.83), EFE (59.0% vs 72.5%, P=.19), moderate or greater tricuspid regurgitation (5.1% vs 5.9%, P=1.00), and similar right ventricular systolic function (indexed tricuspid annular plane systolic excursion 32.5±7.3 vs 31.4±7.2mm/m2, P=.47) in the primary outcome group compared to other patients. Clinical factors associated with primary outcome included lower birth weight (mean, 2.8±SD 0.8 vs 3.3±0.5kg, P=.0003), gestational age <37weeks (31.6% vs 4.9%, P<.0001), longer cardiopulmonary bypass time (median, 112 [IQR, 93-162] vs 82 [71-119] minutes, P=.001), longer intensive care unit length of stay (median, 19 [IQR, 10-30] vs 10 [7-15] days, P=.001), and extracorporeal membrane oxygenation following stage I palliation (43.6% vs 8.8%, P<.0001). Presence of VCCs and EFE was not associated with death or transplant after controlling for birth weight and era of stage I palliation. In one of the largest reported single-center cohorts of HLHS MS/AA, there were few pre-stage I palliation imaging characteristics associated with primary outcome. Imaging findings evaluated in this study, including the presence of VCC and/or EFE as determined using highly sensitive echocardiogram criteria, should not preclude intervention, although impact on long-term outcomes requires further evaluation.

Functional investigation of a novel ANKRD11 frameshift variant identified in a Chinese family with KBG syndrome

KBG syndrome is a rare autosomal dominant condition characterized by multisystem developmental disorder, primarily caused by loss-of-function variants in ankyrin repeat domain-containing protein 11 (ANKRD11). Approximately 80 % of ANKRD11 variants associated with KBG syndrome, are frameshift and nonsense variants. Current insight into the pathogenesis of KBG syndrome resulting from ANKRD11 truncating variants remains limited. Here, we presented two members from a non-consanguineous Chinese pedigree both exhibiting characteristics fitting the KBG syndrome-associated phenotypic spectrum. Whole-exome sequencing identified a novel heterozygous frameshift variant in ANKRD11 (NM_013275.6, c.2280_2281delGT, p.Y761Qfs*20) in the proband. Sanger sequencing confirmed that the variant was inherited from her mother and co-segregated with KBG syndrome phenotype. In vitro functional assays revealed that the frameshift variant escaped nonsense-mediated mRNA decay, and resulting in a truncated protein with significantly increased expression levels compared to full-length ANKRD11. Immunofluorescence results demonstrated that truncated protein was predominantly expressed in the nucleus of HEK293 cells, while wild-type ANKRD11 was equally distributed in both the nucleus and cytoplasm. Moreover, the truncated protein significantly reduced CDKN1A/P21-promoter luciferase activity in comparison to wild-type ANKRD11 protein, as well as a remarkably decrease in the endogenous CDKN1A/P21 mRNA level in HEK293 cells. These findings suggest a loss of transcriptional activation function and potentially a dominant-negative mechanism. Overall, our study expands the mutational spectrum of ANKRD11 gene and provides new insights into the pathogenic mechanism of KBG syndrome caused by ANKRD11 truncating variants.

Multi-omics approaches for drug-response characterization in primary biliary cholangitis and autoimmune hepatitis variant syndrome

BackgroundPrimary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) variant syndrome (VS) exhibit a complex overlap of AIH features with PBC, leading to poorer prognoses than those with PBC or AIH alone. The biomarkers associated with drug response and potential molecular mechanisms in this syndrome have not been fully elucidated.MethodsWhole-transcriptome sequencing was employed to discern differentially expressed (DE) RNAs within good responders (GR) and poor responders (PR) among patients with PBC/AIH VS. Subsequent gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were conducted for the identified DE RNAs. Plasma metabolomics was employed to delineate the metabolic profiles distinguishing PR and GR groups. The quantification of immune cell profiles and associated cytokines was achieved through flow cytometry and immunoassay technology. Uni- and multivariable logistic regression analyses were conducted to construct a predictive model for insufficient biochemical response. The performance of the model was assessed by computing the area under the receiver operating characteristic (AUC) curve, sensitivity, and specificity.FindingsThe analysis identified 224 differentially expressed (DE) mRNAs, 189 DE long non-coding RNAs, 39 DE circular RNAs, and 63 DE microRNAs. Functional pathway analysis revealed enrichment in lipid metabolic pathways and immune response. Metabolomics disclosed dysregulated lipid metabolism and identified PC (18:2/18:2) and PC (16:0/20:3) as predictors. CD4+ T helper (Th) cells, including Th2 cells and regulatory T cells (Tregs), were upregulated in the GR group. Pro-inflammatory cytokines (IFN-γ, TNF-α, IL-9, and IL-17) were downregulated in the GR group, while anti-inflammatory cytokines (IL-10, IL-4, IL-5, and IL-22) were elevated. Regulatory networks were constructed, identifying CACNA1H and ACAA1 as target genes. A predictive model based on these indicators demonstrated an AUC of 0.986 in the primary cohort and an AUC of 0.940 in the validation cohort for predicting complete biochemical response.ConclusionA combined model integrating genomic, metabolic, and cytokinomic features demonstrated high accuracy in predicting insufficient biochemical response in patients with PBC/AIH VS. Early recognition of individuals at elevated risk for insufficient response allows for the prompt initiation of additional treatments.

A rare variant of scimitar syndrome characterised by right pulmonary vein drainage to portal vein with eventeration of diaphragm.

While infradiaphragmatic total anomalous pulmonary venous drainage to portal vein is well described, hemianomalous drainage of right pulmonary veins to portal vein in Scimitar syndrome has not yet been reported.

Correlation of Cerebrospinal Fluid Total Protein and Serum Neutrophil-to-Lymphocyte Ratio with Clinical Outcomes of Guillain-Barre Syndrome Variants.

To evaluate the correlation of cerebrospinal fluid total protein and serum neutrophil-to-lymphocyte ratio with the clinical outcomes and the various clinical and electrophysiological variants of Guillain-Barre syndrome. Cross-sectional study. Place and Duration of the Study: Department of Neurology, Mayo Hospital and King Edward Medical University, Lahore, Pakistan, from November 2022 to April 2023. Fourty-six Guillain-Barre syndrome patients, aged 12-70 years, were included in the study diagnosed by using the Brighton's criteria. Functional disability and respiratory insufficiency were assessed by using the modified Hughes disability score and the Erasmus Guillain-Barre syndrome respiratory insufficiency score, respectively.Serum neutrophil-to-lymphocyte ratio and cerebrospinal fluid total protein were calculated for each patient at the time of admission. Axonal variants had a higher mean neutrophil-to-lymphocyte ratio (5.29 ± 4.38) than demyelinating variants (4.71 ± 3.4) and Miller-Fischer syndrome (3 ± 2.828). This ratio was positively correlated with the modified Hughes's disability score (r = 0.790, p = 0.001) and the Erasmus Guillain-Barre syndrome respiratory insufficiency score (r = 0.936, p = 0.002). Mean cerebrospinal fluid total protein was higher for demyelinating (218 ± 136 mg/dl) than axonal variants (86 ± 56 mg/dl) and Miller-Fischer syndrome (34 ± 21 mg/dl). However, higher modified Hughes disability score (4-6) (r = 0.020, p = 0.117) and a high Erasmus Guillain-Barre syndrome respiratory insufficiency score (5-7) (r = 0.115, p = 0.302) did not significantly affect mean cerebrospinal fluid total proteins. Serum neutrophil-to-lymphocyte ratio can be regarded as a reliable biomarker to assess disease severity and clinical outcome in Guillain-Barre syndrome. Cerebrospinal fluid total protein is a poor predictor of the prognosis and severity of Guillain-Barre syndrome.

Lymphocytic variant of hypereosinophilic syndrome: Diagnostic challenge

T-cell phenotyping by flow cytometry and PCR analysis of TCR gene rearrangement patterns, are necessary to assess the diagnosis of Lymphocytic variant of Hypereosinophilic Syndrome (L-HES). The aim of this study was to evaluate the diagnostic contribution of flow cytometry using a single panel.
