\A systematic literature review of the epidemiology, clinical, economic and humanistic burden in recurrent respiratory papillomatosis
Introduction
Recurrent respiratory papillomatosis (RRP) is a chronic disease caused by human papillomavirus (HPV), characterized by recurrent papillomas in the respiratory tract. Presenting as either juvenile-onset RRP (JoRRP) or adult-onset RRP (AoRRP), the severity of the disease is subjective and unpredictable. Lack of curative therapies necessitates disease management involving repeated surgical removal of lesions. The review aimed to assess the clinical, humanistic and economic burden associated with RRP.

and Cochrane databases were conducted for epidemiology, clinical, humanistic, and economic burden, from database inception to November 30, 2022. Conference abstracts were also searched (2019–2022). Key inclusion criteria consisted of juveniles or adults with RRP/laryngeal papillomatosis, with no restriction on study country, interventions, or comparators. Outcomes of interest included incidence, prevalence, risk factors, symptomatic presentation, HPV genotype, cost burden, resource use and health related quality of life (HRQoL).
Results
In JoRRP, the incidence rate ranged from 0.2–2.1 per 100,000 and the prevalence rate ranged from 0.8–4.3 per 100,000. Incidence and prevalence of AoRRP were 0.2–3.9 and 0.4–8.4 per 100,000, respectively. Limited studies reported the subsequent impact of introducing national prophylactic HPV immunisation programs on JoRRP epidemiology, but where available, they were associated with significantly reduced incidence rates. Symptomatic presentations were diverse, with voice impact and breathing difficulties commonly reported. More aggressive disease was linked to earlier age of onset and HPV11 genotype. Healthcare utilisation was largely driven by surgical interventions, due to lack of curative treatments. Cost burden was substantial, with JoRRP associated with triple the costs of AoRRP in the US. Patients with JoRRP and AoRRP experienced considerable HRQoL impairment, particularly relating to voice disorder.
Conclusion
Extensive clinical, humanistic and economic disease burden was reported for both JoRRP and AoRRP, as it is a chronic condition, with propensity to recur and spread. Feasibility of improving HPV prophylactic vaccination coverage against HPV6/HPV11 should be explored to reduce incidence, alongside efforts to improve treatment of JoRRP and AoRRP patients. Despite the existing literature, RRP remains a poorly understood disease, and future research on risk factors and medical options are needed.

Reactive haemophagocytic syndrome in adult-onset Still’s disease: a report of six patients and a review of the literature
Objective: To examine the prevalence and characteristics of patients with reactive haemophagocytic syndrome (RHS) complicating adult-onset Still’s disease (AOSD). Methods: Of 50 patients with AOSD fulfilling Yamaguchi and Fautrel criteria followed in our department, clinical and laboratory data, course and treatment of six patients with histologically proven RHS and without any obvious cause other than AOSD were retrospectively recorded. Results: RHS led to AOSD in two cases, whereas it appeared after a mean duration of 3.5 years from onset of AOSD in the other cases. The main symptoms were fever (n = 6), polyarthralgias or myalgias (n = 4), lymphadenopathy or splenomegaly (n = 3), pharyngitis (n = 3), rash (n = 3), pleuritis (n = 3), hepatomegaly (n = 1), normal or low leucocyte count (n = 4), anaemia (n = 6), lymphocytopenia (n = 6), thrombocytopenia (n = 4), hyperbasophilic lymphocytes (n = 2), abnormal liver function tests (n = 6) and increased serum triglyceride level (n = 6). Serum ferritin concentration was constantly increased (>10 000 µg/l in five cases, with <5–35% in glycosylated form). Two patients presented with coagulopathy. Treatment comprised corticosteroids (n = 4) and intravenous immunoglobulins (n = 3), whereas prednisone was unchanged in one case. One death due to pneumonia occurred 15 days after RHS. With a follow-up ranging from 2 to 7.5 years, the other patients were in remission with prednisone plus etanercept (n = 1), prednisone plus methotrexate (n = 1), low-dose prednisone (n = 2) or without treatment (n = 1). Conclusion: RHS is not uncommon in AOSD. It should be evoked in a patient with AOSD in the absence of hyperleucocytosis, thrombocytopenia, lymphopenia and coagulopathy, or in the presence of high serum ferritin and triglyceride levels.

Neonatal systemic juvenile Xanthogranuloma with Hydrops diagnosed by Purpura skin biopsy: a case report and literature review
Background
Systemic juvenile xanthogranuloma is a very rare disease typically presents as skin lesions with yellow papules or nodules and is sometimes fatal. We report a case of congenital neonatal systemic juvenile xanthogranuloma with atypical skin appearance that made the diagnosis difficult.
Case presentation
A preterm Japanese female neonate with prenatally diagnosed fetal hydrops in-utero was born with purpuric lesions involving the trunk and face. Since birth, she had hypoxemic respiratory failure, splenomegaly, anemia, thrombocytopenia, coagulopathy, and was transfusion dependent for red blood cells, fresh frozen plasma, and platelets. Multiple cystic lesions in her liver, part of them with vascular, were detected by ultrasound. A liver biopsy was inconclusive. A skin lesion on her face similar to purpura gradually changed to a firm and solid enlarged non-yellow nodule. Technically, the typical finding on skin biopsy would have been histiocytic infiltration (without Touton Giant cells) and immunohistochemistry results which then would be consistent with a diagnosis of systemic juvenile xanthogranuloma, and chemotherapy improved her general condition.
Conclusions
This case report shows that skin biopsies are necessary to detect neonatal systemic juvenile xanthogranuloma when there are organ symptoms and skin eruption, even if the skin lesion does not have a typical appearance of yellow papules or nodules.
