Looking back and beyond the 2017 diagnostic criteria for hypermobile Ehlers-Danlos syndrome: A retrospective cross-sectional study from an Italian reference center.

The most common conditions with symptomatic joint hypermobility are hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD). Diagnosing these overlapping connective tissue disorders remains challenging due to the lack of established causes and reliable diagnostic tests. hEDS is diagnosed applying the 2017 diagnostic criteria, and patients with symptomatic joint hypermobility but not fulfilling these criteria are labeled as HSD, which is not officially recognized by all healthcare systems. The 2017 criteria were introduced to improve diagnostic specificity but have faced criticism for being too stringent and failing to adequately capture the multisystemic involvement of hEDS. Herein, we retrospectively evaluated 327 patients from 213 families with a prior diagnosis of hypermobility type EDS or joint hypermobility syndrome based on Villefranche and Brighton criteria, to assess the effectiveness of the 2017 criteria in distinguishing between hEDS and HSD and document the frequencies of extra-articular manifestations. Based on our findings, we propose that the 2017 criteria should be made less stringent to include a greater number of patients who are currently encompassed within the HSD category. This will lead to improved diagnostic accuracy and enhanced patient care by properly capturing the diverse range of symptoms and manifestations present within the hEDS/HSD spectrum.

Despite celiprolol therapy, patients with vascular Ehlers-Danlos syndrome remain at risk of vascular events: A 12-year experience in an Italian referral center.

BACKGROUND: Vascular Ehlers-Danlos syndrome (vEDS) is an inherited connective tissue disorder characterized by arterial fragility. Celiprolol has been suggested to significantly reduce rates of vascular events in this setting, though real-world evidence is limited. The aim of this study was to report our experience with celiprolol therapy in vEDS management. METHODS: Patients with a genetically confirmed diagnosis of vEDS who were referred for outpatient consultation at the Brescia University Hospital between January 2011 and July 2023 were included. At each visit, patients' medical history, results of vascular imaging, and office blood pressure measurements were recorded. Celiprolol therapy was progressively titrated to the maximum tolerated dose of up to 400 mg daily, according to the patients' tolerance. RESULTS: Overall, 26 patients were included. Female sex was prevalent (62%). Mean (SD) age was 37 (16) years. Follow-up duration was 72 (41) months. At the last follow-up visit, all patients were on celiprolol therapy, 80% of whom were taking the maximum recommended dose. The yearly risk of symptomatic vascular events was 8.8%, the majority of which occurred after reaching the maximum recommended dose of celiprolol. No significant predictor of symptomatic vascular events was identified among patients' clinical characteristics. CONCLUSION: In our cohort, rates of celiprolol use were high and the drug was well tolerated overall. Nonetheless, the risk of symptomatic vascular events remained nonnegligible. Future studies should identify reliable predictors of major adverse events and explore additional therapeutic strategies that could further lower the risk of life-threatening events in this population.

Finger nodules with a papulovesicular hands and feet eruption: a complicated human Orf virus infection.

BACKGROUND: Orf virus (ORFV) is the pathogen responsible for Orf, a zoonotic viral infection that can be spread to humans from sheep and goats. Here, we present a case of human Orf complicated by an immune-related reaction, to raise awareness of this under-recognized disease avoiding unnecessary investigations and overtreatment. CASE REPORT: A 51-year-old woman with no previous medical history presented with a one-week history of three asymptomatic swelling nodules with a grey necrotic center and red outer halo on her index finger. At physical examination there was also a pruritic papulovesicular eruption on her hands and feet. She reported a recent contact with a goat which had a similar nodular lesion in its mouth. A biopsy of the lesions was performed and a diagnosis of Orf complicated by widespread erythema multiforme was made based on the clinical and histopathological features. The lesions spontaneously resolved within the next 2 weeks. CONCLUSIONS: Orf is not very prevalent in our region, so we performed a biopsy of the lesion to guide us toward a diagnosis. However, we should remember that the diagnosis of ecthyma relies on clinical evaluation and epidemiological criteria.

How to integrate surgery and targeted therapy with biologics for the treatment of hidradenitis suppurativa: Delphi consensus statements from an Italian expert panel.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by recurrent and painful nodules and abscesses in intertriginous skin areas, which can progress to sinus tract formation, tissue destruction, and scarring. HS is highly debilitating and severely impairs the psychological well-being and quality of life of patients. The therapeutic approach to HS is based on medical therapy and surgery. First-line medical therapy includes topical antibiotics, systemic antibiotics, and biologics. Main surgical procedures include deroofing, local excision, and wide local excision. Despite the availability of multiple therapeutic options, the rates of disease recurrence and progression continue to be high. In recent years, the possibility of combining biologic therapy and surgery has raised considerable interest. In a clinical trial, the perioperative use of adalimumab has been associated with greater response rates and improved inflammatory load and pain, with no increased risk of postoperative infectious complications. However, several practical aspects of combined biologic therapy and surgery are poorly defined. In June 2022, nine Italian HS experts convened to address issues related to the integration of biologic therapy and surgery in clinical practice. To this purpose, the experts identified ten areas of interest based on published evidence and personal experience: 1) patient profiling (diagnostic criteria, disease severity classification, assessment of response to treatment, patient-reported outcomes, comorbidities); 2) tailoring surgery to HS characteristics; 3) wide local excision; 4) pre-surgery biologic treatment; 5) concomitant biologic and surgical treatments; 6) pre- and post-surgery management; 7) antibiotic systemic therapy; 8) biologic therapy after radical surgery; 9) management of adverse events to biologics; 10) management of postoperative infectious complications. Consensus between experts was reached using the Estimate-Talk-Estimate method (Delphi Method). The statements were subsequently presented to a panel of 27 HS experts from across Italy, and their agreement was assessed using the UCLA Appropriateness Method. This article presents and discusses the consensus statements.

Diversity in the clinical presentation of generalized pustular psoriasis (GPP): A series of case vignettes from around the world.

A key principle of clinical studies and case reports is that they should reflect the demographics and epidemiology of the patient population concerned. Here, we have compiled a diverse group of clinical cases of generalized pustular psoriasis (GPP) to showcase the differences in GPP presentation in patients worldwide. We attempt to capture the broad spectrum of clinical presentations of GPP and showcase the diversity of the patient population. The patients included in this series are diverse in age, genetic background, skin phototype and medical history. Moreover, they present with a variety of clinical courses of GPP and different degrees of systemic involvement, and experience flares triggered by different inciting factors. The key learnings from this case series may support physicians in identifying and managing patients with this rare and multifaceted disease that can affect patients both physically and psychologically.

SARS-CoV-2 Detection by Digital Polymerase Chain Reaction and Immunohistochemistry in Skin Biopsies from 52 Patients with Different COVID-19-Associated Cutaneous Phenotypes.

BACKGROUND: COronaVIrus Disease 19 (COVID-19) is associated with a wide spectrum of skin manifestations, but SARS-CoV-2 RNA in lesional skin has been demonstrated only in few cases. OBJECTIVE: The objective of this study was to demonstrate SARS-CoV-2 presence in skin samples from patients with different COVID-19-related cutaneous phenotypes. METHODS: Demographic and clinical data from 52 patients with COVID-19-associated cutaneous manifestations were collected. Immunohistochemistry and digital PCR (dPCR) were performed in all skin samples. RNA in situ hybridization (ISH) was used to confirm the presence of SARS-CoV-2 RNA. RESULTS: Twenty out of 52 (38%) patients presented SARS-CoV-2 positivity in the skin. Among these, 10/52 (19%) patients tested positive for spike protein on immunohistochemistry, five of whom had also positive testing on dPCR. Of the latter, one tested positive both for ISH and ACE-2 on immunohistochemistry while another one tested positive for nucleocapsid protein. Twelve patients showed positivity only for nucleocapsid protein on immunohistochemistry. CONCLUSIONS: SARS-CoV-2 was detected only in 38% of patients, without any association with a specific cutaneous phenotype, suggesting that the pathophysiology of cutaneous lesions mostly depends on the activation of the immune system. The combination of spike and nucleocapsid immunohistochemistry has higher diagnostic yield than dPCR. Skin persistence of SARS-CoV-2 may depend on timing of skin lesions, viral load, and immune response.

Bath-PUVA still represents a valuable treatment option for the subsets of psoriatic patients who are not eligible to or rejecting systemic treatments and are not responsive to NB-UVB phototherapy.

BACKGROUND: Photochemotherapy with bathwater delivery of psoralens plus UVA exposures (bath-PUVA) is mainly used for those psoriatic patients who are not responsive to narrowband (NB)-UVB phototherapy and oral-PUVA therapy and belong to two categories (1) patients with psoriasis without systemic comorbidities who do not need long-term continuous treatment and (2) patients who have contraindications to immunosuppressive drugs and oral-PUVA or refuse systemic drugs, including oral ingestion of psoralens, for personal reasons. However, it is not known how many patients belong to the second group and how much bath-PUVA is effective and safe for them. METHODS: We have reviewed the treatment results of a cohort of 120 patients with clinical indication to bath-PUVA for the above-mentioned reasons between 2010 and 2019. These patients were selected among 2640 patients with moderate and severe psoriasis who were treated in our department in the same time interval. RESULTS: Ninety-six patients completed at least one treatment cycle with bath-PUVA. A per-protocol analysis showed that average number of treatment sessions was 21.3 ± 9.0 and the cumulative UVA dose was 80.4 ± 60.0 J/cm2 . The average PASI scores decreased from 20.8 ± 7.9 to 5.1 ± 5.4 (p < .01). Sixty-seven (69.7%) patients achieved at least a 75% improvement (PASI75 ) and, of them, 38 (39.6%) had an improvement greater than 90% (PASI90 ). Adverse effects were mild and transitory. CONCLUSION: These findings demonstrate that bath-PUVA is still a valuable treatment option for a high number of patients who reject systemic treatments or have contraindications to systemic immune-modifying drugs and have had a limited or no improvement with NB-UVB phototherapy.

Hidradenitis Suppurativa in a Large Cohort of Italian Patients: Evaluation of the Burden of Disease.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease of the hair follicle that usually occurs after puberty with painful, deep-seated, inflamed nodules and sinus tracts in the apocrine gland-bearing areas of the body, most commonly the axillae and inguinal and anogenital regions, with a relevant impact on patients' quality of life (QoL). OBJECTIVE: To evaluate how the burden of HS disease impacts on patient well-being and working activities in a large Italian population over a period of 9 months. METHODS: A multicenter, prospective, epidemiologic cohort study was conducted in adult Italian patients with HS. HS severity was assessed through Hurley stage and HS Physician's Global Assessment (HS-PGA), clinical improvement by HS Clinical Response (HiSCR) and partial response, and disease burden through QoL questionnaires (HIDRAdisk, Skindex-16, Dermatology Life Quality Index [DLQI]), and Work Productivity and Activity Impairment - General Health (WPAI:GH). RESULTS: A total of 308 patients (56.2% women; mean age 35.2 ± 12.9 years) were enrolled in 27 dermatologic clinics. Men were older (37.4 years vs. 33.5), more smoking addicted (74.1% vs. 60.1%), and alcohol consumer (34.1% vs. 13.9%), while more women were obese (34.10% vs. 22.22%). At baseline, most patients had a Hurley severity stage of 2 (43.9%), a moderate HS-PGA score (57.1%), and poor QoL (HIDRAdisk: 65.7 ± 23.3, Skindex-16: 60.3 ± 26.9, and DLQI: 10.8 ± 8.1). Patients with more severe disease showed worse QoL. Mean values for the variables related to HS severity decreased during the study period. The achievement of HiSCR and partial response increased during the study. CONCLUSION: This study offers insight into the disease burden of HS in an Italian population. Our results underline the impact of QoL evaluation, also with the use of the HIDRAdisk, in clinical routine as a support to validated severity clinical and instrumental indexes for a "360-degree" assessment of HS patient's burden of disease.

A Short Cycle of Narrow-Band UVB Phototherapy in the Early Phase of Dupilumab Therapy Can Provide a Quicker Improvement of Severe Atopic Dermatitis.

BACKGROUND: Since the best clinical response to dupilumab is achieved after 12-16 weeks, a combination therapy at the beginning of the treatment could be a helpful strategy to reach a faster response in patients with severe atopic dermatitis (AD). OBJECTIVES: To quantify the benefit of a combination of dupilumab treatment with a short course of narrow-band ultraviolet B (NB-UVB) phototherapy. METHODS: In the present pilot study adult patients suffering from severe AD were enrolled with a 2:1 ratio to receive treatment with dupilumab alone or dupilumab plus NB-UVB phototherapy, for 12 weeks. After the twelfth week, all patients received dupilumab only. A follow-up visit took place after 16 weeks. Both clinician-oriented and patient-oriented scores were assessed at baseline (T0) and after 4 (T1), 12 (T2) and 16 (T3) weeks. RESULTS: Forty-five adult patients were enrolled in the study. Both treatment regimens were well tolerated and very effective on all measured scores (EASI, SCORAD, BSA, NRS of itching, NRS of sleep loss, DLQI, POEM and HADS), but the combined regimen led to a more robust clinical improvement of lesions and relief of symptoms after 4 weeks. However, after 12 and 16 weeks, the additional therapeutic effect of phototherapy weakened. CONCLUSION: NB-UVB phototherapy can provide a faster remission of severe AD in the first few weeks of dupilumab therapy.

Sunlight-induced Painful Skin (Sun Pain): A New Differential Diagnosis in Photodermatology.

Photodermatoses are characterized by the development of skin eruptions following exposure to ultraviolet radiation or visible light. We report here the clinical findings and results of laboratory investigations and phototesting of 6 patients who experience debilitating and excruciating pain after sun exposure ("sun pain") in the absence of any skin eruption. Phototesting with sub-erythemal doses of ultraviolet A radiation triggered localized pain in 4 patients. At follow-up, 3 female patients were found to have developed fibromyalgia, 2 male patients experienced a major depressive disorder, and another male patient had a conversion disorder. One patient also developed allodynia to tactile stimuli and one developed allodynia to thermal and tactile stimuli. Psychiatric conditions should be taken into consideration in patients presenting with excruciating and debilitating pain on exposure to ultraviolet radiation, but with absence of skin eruption. Further research is needed to evaluate whether it represents a type of allodynia triggered by exposure to ultraviolet radiation.

Secukinumab Exhibits Sustained and Stable Response in Patients with Moderate-to-Severe Psoriasis: Results from the SUPREME Study.

Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in terms of Psoriasis Area and Severity Index (PASI) 90 in patients with moderate-to-severe plaque psoriasis. Based on PASI 90 response at week 16, patients were stratified as PASI 90 responders (PASI90R, n = 337) or non-responders (PASI90NR, n = 72). At week 20, 94.2% (n = 295/313) achieved PASI 90/100 response in PASI90R, with response maintained through week 48 (89.6%, n = 189/211). An increased proportion of patients achieved PASI 90/100 response in PASI90NR (week 20: 29.9%, n = 20/67; week 48: 57.1%, n = 20/35). Overall, 64.4% patients achieved absolute PASI score = 0 at week 24 with response sustained to week 48 (66.9%). Secukinumab showed sustained and stable efficacy in maintaining PASI 90 response in patients with moderate-to-severe plaque psoriasis up to week 48.

Italian expert-based recommendations on the use of photo(chemo)therapy in the management of mycosis fungoides: Results of an e-Delphi consensus.

BACKGROUND: Phototherapy is a mainstay for the treatment of MF. However, there is scarce evidence for its use, mostly due to the lack of a unified schedule. AIMS: The primary aim of this study was to establish the first structured, expert-based consensus regarding the indications and technical schedules of NB-UVB and PUVA for MF. The secondary aim was to determine the consensus level for each specific item. MATERIALS & METHODS: E-delphi study. Item-specific expert consensus was defined as the number of "Totally Agree" results to ≥80% of the panelists. Cronbach alpha index ≥0.7 was used as a measure of homogeneity in the responses among questions related to the same topic. RESULTS: Overall, there was a high homogeneity among responders (0.78). On specific topics, the highest grade was observed for technical items (0.8) followed by indications for early (0.73) and advanced stages (0.7). CONCLUSIONS: Items related to the most canonical indications of phototherapy and to treatment schedules showed the highest agreements rates. There is consensus about the use of standardized treatment schedules for the induction and consolidation phases for NB-UVB and PUVA in MF.

Application of the 2017 criteria for vascular Ehlers-Danlos syndrome in 50 patients ascertained according to the Villefranche nosology.

Vascular Ehlers-Danlos syndrome (vEDS) is a rare inherited connective tissue disorder due to heterozygous pathogenic COL3A1 variants. Arterial, intestinal, and/or uterine fragility is the disease hallmark and results in reduced life expectancy. The clinical diagnosis is not always straightforward and patients' selection for molecular confirmation depends on the characteristics of applied criteria, that is, the Villefranche criteria (in use until 2017) and their revision according to the new EDS nosology. Herein, we reassessed the clinical features of 50 molecularly proven vEDS patients, diagnosed according to the Villefranche nosology between 2000 and 2016, using the 2017 classification in order to explore its clinical application. Our findings indicate that the Villefranche criteria were particularly valuable for symptomatic patients, even if with a limited specificity. Our study also suggests that the revised vEDS criteria, although expected to be more specific, might have a poorer accuracy, principally in terms of sensitivity. Both sets of criteria are less effective in presymptomatic young patients, especially in the absence of a clear-cut family history. For these patients, the careful evaluation of the cutaneous, articular, and dysmorphic features and, above all, genetic testing remain crucial to set-up proper follow-up and surveillance before catastrophic vascular and intestinal events.

Photosensitivity and cancer immune-targeted therapies.

The novel group of immunological agents used for solid tumors has importantly improved the quality of life and the survival rate of oncologic patients. Compared to conventional chemotherapy agents, they are more effective and less toxic. However, adverse cutaneous effects are commonly observed, and in some cases, they may induce treatment discontinuation, with heavy impact on patient prognosis. Among these, photosensitive reactions, either phototoxic or photoallergic, are increasing. Much remains to be clarified on the understanding of their prevention, diagnosis, and management. We have reviewed the literature about photosensitive reactions occurring during oncologic immunotherapies. Early dermatological diagnosis and adequate management, with oncologist's cooperation, is fundamental.

Clinical and Spectrophotometric Evaluation of Skin Photoadaptation in Vitiligo Patients after a Short Cycle of NB-UVB Phototherapy.

BACKGROUND: The phenomenon of photoadaptation to narrow-band ultraviolet B (NB-UVB) radiation has been previously described in vitiligo and has usually been clinically measured by the assessment of the minimal erythema dose (MED) after phototesting. OBJECTIVES: To assess the photoadaptive response in vitiligo and healthy skin after NB-UVB phototherapy not only clinically, but also by spectrophotometry. MATERIALS AND METHODS: Fourteen patients affected by generalized vitiligo underwent NB-UVB phototherapy twice weekly for 12 weeks. Before and after phototherapy, a phototesting procedure was administered on vitiligo patches and adjacent healthy skin with a solar simulated radiation (SSR). Visual assessment of the MED took place after 24 h. A spectrophotometer was used to assess the a* value and the melanin index (MI*), as signs of skin erythema and pigmentation. The photoadaptation factor (MED-PF) and the a* photoadaptation factor (a*-PF) were calculated. RESULTS: After NB-UVB phototherapy, both vitiligo and healthy skin showed an increase in MED and MI* values and a reduction of skin erythema compared to baseline (p < 0.05). MED-PF data showed a photoadaptation in 10 (71.4%) vitiligo lesions and in 12 (85.7%) healthy skin areas. The assessment of the a*-PF showed a negative mean percentage value in all affected and unaffected skin areas. CONCLUSIONS: A short cycle of NB-UVB phototherapy can induce photoadaptation in vitiligo by increasing the MED and reducing skin erythema after stimulation with SSR. This is most likely due to the physical filter function induced by ultraviolet radiation.

Prevalence of Phototherapy in the Age of Biologics.

BACKGROUND: The prevalence of narrow-band ultraviolet B (NB-UVB) use in Europe for moderate and severe psoriasis is unknown, because national registries for psoriasis do not monitor this treatment. OBJECTIVES: To quantify the use of phototherapy, biologics or conventional treatments in psoriasis, in a setting where European Medicines Agency (EMA) eligibility criteria for biologics were strictly applied, and phototherapy was included among first-line treatments. METHODS: We followed a cohort of 1,090 patients who were referred to the only centre entitled to prescribe biologics and phototherapy during a 5-year period. RESULTS: The cumulative number of treatment cycles was: 1,047 with NB-UVB phototherapy, 650 with systemic treatments and 239 with biologics; 754 patients received at least 1 course of NB-UVB phototherapy, 422 at least 1 course with a systemic treatment and 137 with a biologic; 595 patients were treated only with phototherapy. CONCLUSIONS: Regular use of NB-UVB as first-line treatment for moderate and severe psoriasis and adherence to the EMA eligibility criteria for biologics led to a relatively restricted use of biologics.

Delineation of Ehlers-Danlos syndrome phenotype due to the c.934C>T, p.(Arg312Cys) mutation in COL1A1: Report on a three-generation family without cardiovascular events, and literature review.

Classical Ehlers-Danlos syndrome (cEDS) is a rare connective tissue disorder primarily characterized by hyperextensible skin, defective wound healing, abnormal scars, easy bruising, and generalized joint hypermobility; arterial dissections are rarely observed. Mutations in COL5A1 and COL5A2 encoding type V collagen account for more than 90% of the patients so far characterized. In addition, cEDS phenotype was reported in a small number of patients carrying the c.934C>T mutation in COL1A1 that results in an uncommon substitution of a non-glycine residue in one Gly-Xaa-Yaa repeat of the pro-α1(I)-chain p.(Arg312Cys), which leads to disturbed collagen fibrillogenesis due to delayed removal of the type I procollagen N-propeptide. This specific mutation has been associated with propensity to arterial rupture in early adulthood; indeed, in literature the individuals harboring this mutation are also referred to as "(classic) vascular-like" EDS patients. Herein, we describe a three-generation cEDS family with six adults carrying the p.(Arg312Cys) substitution, which show a variable and prevalent cutaneous involvement without any major vascular event. These data, together with those available in literature, suggest that vascular events are not a diagnostic handle to differentiate patients with the p.(Arg312Cys) COL1A1 mutation from those with COL5A1 and COL5A2 defects, and highlight that during the diagnostic process the presence of at least the p.(Arg312Cys) substitution in COL1A1 should be investigated in cEDS patients without type V collagen mutations. Nevertheless, for these patients, as well as for those affected with cEDS, a periodical vascular surveillance should be carried out together with cardiovascular risk factors monitoring. © 2016 Wiley Periodicals, Inc.

Marfan syndrome: Report of a complex phenotype due to a 15q21.1 contiguos gene deletion encompassing FBN1, and literature review.

Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder that primarily involves skeletal, ocular, and cardiovascular systems with large inter- and intra-familial variability in terms of age of onset, severity, and aortic disease. The causal gene, FBN1, encodes for fibrillin 1, a multi-domain glycoprotein essential for many biological functions, including deposition and formation of elastic fibers. Reports describing chromosomal alterations involving FBN1 are rare, but in the last years their number has increased after copy number state analyses, such as multiplex ligation-dependent probe amplification and microarray-based comparative genomic hybridization, were adopted as routine diagnostic tools. Herein we report a patient with MFS and an atypical facial appearance and neuropsychiatric involvement likely not attributable to MFS due to a 15q21.1 deletion that involves part of FBN1 and 13 additional contiguous genes listed in OMIM. We compare his phenotype with those of the few patients described in the literature who share similar 15q11.2 deletions. This report expands the phenotype of patients with 15q11.2 deletion involving FBN1 and its contiguous genes, and suggests a possible role for these other genes in the pathogenesis of the observed unusual clinical signs that are not explained by FBN1 haploinsufficiency. © 2016 Wiley Periodicals, Inc.

Refining patterns of joint hypermobility, habitus, and orthopedic traits in joint hypermobility syndrome and Ehlers-Danlos syndrome, hypermobility type.

Joint hypermobility syndrome (JHS) and Ehlers-Danlos syndrome, hypermobility type (EDS-HT) are two overlapping heritable disorders (JHS/EDS-HT) recognized by separated sets of diagnostic criteria and still lack a confirmatory test. This descriptive research was aimed at better characterizing the clinical phenotype of JHS/EDS-HT with focus on available diagnostic criteria, and in order to propose novel features and assessment strategies. One hundred and eighty-nine (163 females, 26 males; age: 2-73 years) patients from two Italian reference centers were investigated for Beighton score, range of motion in 21 additional joints, rate and sites of dislocations and sprains, recurrent soft-tissue injuries, tendon and muscle ruptures, body mass index, arm span/height ratio, wrist and thumb signs, and 12 additional orthopedic features. Rough rates were compared by age, sex, and handedness with a series of parametric and non-parametric tools. Multiple correspondence analysis was carried out for possible co-segregations of features. Beighton score and hypermobility at other joints were influenced by age at diagnosis. Rate and sites of joint instability complications did not vary according to age at diagnosis except for soft-tissue injuries. No major difference was registered by sex and dominant versus non-dominant body side. At multiple correspondence analysis, selected features tend to co-segregate in a dichotomous distribution. Dolichostenomelia and arachnodactyly segregated independently. This study pointed out a more protean musculoskeletal phenotype than previously considered according to available diagnostic criteria for JHS/EDS-HT. Our findings corroborated the need for a re-thinking of JHS/EDS-HT on clinical grounds in order to find better therapeutic and research strategies. © 2017 Wiley Periodicals, Inc.

Further delineation of FKBP14-related Ehlers-Danlos syndrome: A patient with early vascular complications and non-progressive kyphoscoliosis, and literature review.

FKBP14-related Ehlers-Danlos syndrome (EDS) is an extremely rare recessive connective tissue disorder described for the first time in 2012 by Baumann and coworkers. The causal gene, FKBP14, encodes a member of the F506-binding family of peptidyl-prolyl cis-trans isomerases. The paucity of patients described so far makes this disorder poorly defined at clinical level. Here, we report an additional pediatric patient, who is compound heterozygous for a recurrent and a novel FKBP14 mutation, and compare his phenotype with those available in literature. This evaluation confirms that kyphoscoliosis (either progressive or non-progressive), myopathy, joint hypermobility, and congenital hearing loss (sensorineural, conductive, or mixed) are the typical features of the syndrome. Since the patient showed a severe cardiovascular event in childhood and atlantoaxial instability, this report expands the phenotype of the disorder and the allelic repertoire of FKBP14. © 2016 Wiley Periodicals, Inc.
