Two-year multidisciplinary follow-up of COVID-19 patients requiring invasive and noninvasive respiratory support.

Background: COVID-19 patients frequently develop respiratory failure requiring mechanical ventilation. Data on long-term survival of patients who had severe COVID-19 are insufficient. We assessed and compared two-year survival, CT imaging, quality of life, and functional recovery of COVID-19 ARDS patients requiring respiratory support with invasive (IMV) versus noninvasive ventilation (NIV).

Histopathological progression of hidradenitis suppurativa/acne inversa : A morphological study with a closer look on the early changes of the folliculosebaceous apocrine apparatus.

Background: It is generally acknowledged that the first morphological change of hidradenitis suppurativa/acne inversa (HS/AI) consists of infundibular plugging of the folliculosebaceous apocrine apparatus, which is followed by acute and chronic inflammation, cysts with sinus formation, and fibrosis. Alternatively, it has been hypothesized that HS/AI is primarily a neutrophilic autoinflammatory disease and that the follicular plugging typical of this disease is secondary to inflammation.

Objective: To review the sequence of the changes that mark the disease development, we have performed a histopathologic study on the surgical material from a series of axillary and inguinal/perineal cases.

Outcomes of noninvasive ventilation as the ceiling of treatment in patients with COVID-19.

Background: Non-invasive mechanical ventilation (NIV) is effective for symptom relief and respiratory support in patients with respiratory insufficiency, severe comorbidities and no indication to intubation. Experience with NIV as the ceiling of treatment in severely compromised novel coronavirus disease (COVID-19) patients is lacking.

Methods: We evaluated 159 patients with COVID-19-related acute respiratory syndrome (ARDS), 38 of whom with NIV as the ceiling of treatment, admitted to an ordinary ward and treated with continuous positive airway pressure (CPAP) and respiratory physiotherapy.

Continuous positive airway pressure and pronation outside the Intensive Care Unit in COVID-19 acute respiratory distress syndrome.

Background: The efficacy and safety of continuous positive airway pressure and respiratory physiotherapy outside the Intensive Care Unit during a pandemic.

Methods: In this cohort study performed in February-May 2020 in a large teaching hospital in Milan, COVID-19 patients with adult respiratory distress syndrome receiving continuous positive airway pressure (positive end-expiratory pressure =10 cm H2O, FiO2=0.6, daily treatment duration: 4×3h-cycles) and respiratory physiotherapy including pronation outside the Intensive Care Unit were followed-up.

Secukinumab efficacy in the treatment of nail psoriasis: a case series.

Nail involvement is frequent in patients with psoriasis, especially those with psoriatic arthritis (PsA), and can significantly impair quality of life (QoL). It is typically difficult to treat compared with skin lesions, although several conventional treatment options are available. The aim of this article is to describe our experience in the treatment of nail psoriasis with secukinumab in a case series.

A Case of Moderate Hidradenitis Suppurativa and Psoriasis Treated with Secukinumab.

Hidradenitis suppurativa (HS) is a disorder of the apocrine gland causing a chronic, recurrent and painful inflammation. It is a disabilitating condition and, though many therapeutic options are available, the response is often ineffective in most cases and patients can present many recurrences with physical and psychological sequelae. Recent data had shown increased interleukin (IL)-17 serum levels in patients with HS.

Plexiform Atypical Spitz Tumor With Rosette-Like Giant Cells: A Histologic and Immunohistochemical Study on a Case Suggesting Ganglioneuroblastic Differentiation: Review of the Literature and Considerations on Histogenesis.

Spitz nevi, atypical Spitz tumors and Spitzoid melanoma, the three clinicopathologic forms that constitute the spectrum of the Spitz-type melanocytic lesions, share a histologic picture characterized by large spindle and/or epithelioid ganglion-like cells, with various admixtures of multinucleate bizarre cells. This remarkable cytology has always been interpreted as an unusual, as well as unexplained form of atypia. We report a case of atypical Spitz tumor with Homer Wright-like rosettes, a feature characteristic of ganglioneuroblastic proliferation.

Postherpetic neuralgia, diabetic neuropathy, and trigeminal neuralgia - Chronic peripheral neuropathic pain in 58,480 rural Italian primary care patients.

Introduction: Chronic peripheral neuropathic pain (CPNP) is a condition due to peripheral nervous system diseases or injury, but its prevalence is unknown in Italian primary care.

Aim: The aim of this study is to assess the prevalence of CPNP in a rural primary care area in Northern Italy.

Materials And Methods: A multicenter audit study was carried out in a rural area in Northern Italy with 113 participating general practitioners (GPs) seeing 58,480 patients >18 years during 3 months.

Vulvar cancer: a review for dermatologists.

Vulvar malignancies are important tumors of the female reproductive system. They represent a serious health issue with an incidence between 2 and 7 per 100,000 and year. We provide a review about most important cancer entities, i.

Avian mite dermatitis: an Italian case indicating the establishment and spread of Ornithonyssus bursa (Acari: Gamasida: Macronyssidae) (Berlese, 1888) in Europe.

Background: Avian mite dermatitis is a skin disease caused in mammals by the incidental bites of blood-sucking mites which customarily parasitize wild and domestic birds. It manifests in the form of pruritic, erythematous, or urticarial papules, with a central sting mark, in skin regions normally covered by clothing. The species mainly implicated in human bite cases are Dermanyssus gallinae, Ornithonyssus sylviarum and, less frequently, Ornithonyssus bursa.

Environmental effects of storage preservation practices: controlled flushing of fine sediment from a small hydropower reservoir.

Sediment flushing may be effective in mitigating loss of reservoir storage due to siltation, but flushing must be controlled to limit the impact on the downstream environment. A reliable prediction of the environmental effects of sediment flushing is hindered by the limited scientific information currently available. Consequently, there may be some controversy as regards to management decisions, planning the work, and monitoring strategies.

Perineural pattern of aggregation of cellular blue nevus: probable histoarchitectural reminiscence of histogenesis.

A striking feature of cellular blue nevus consists in the presence, in its histologic picture, of numerous hypertrophic nerves and nerve-like figures, positive for histochemical and immunohistochemical methods for nerve fibers and myelin sheaths. These findings, first described in Masson's original article and repeatedly highlighted in the past for their possible histogenetic significance, are currently considered as merely coincidental. However, the thin conventional histologic sections, catching only short tracts of the nerves, preclude a correct observation of their route and do not allow us to verify if there is an architectural relationship between them and the nevus as a whole.

Local reactions to tick bites.

A retrospective histological and immunohistochemical study has been carried out in 25 cases of tick bites recorded in our Departments. The samples that included an attached tick showed a cement cone anchoring the mouthparts to the skin and a blood-soaked, spongiform appearance of the superficial dermis, with a mild neutrophilic and eosinophilic infiltration. The vessels displayed a loose multilayered endothelial proliferation, with plump endothelia, permeated with erythrocytes.

Extramammary Paget Disease of the Axilla Associated With Comedo-like Apocrine Carcinoma In Situ.

Extramammary Paget disease of the axilla with underlying apocrine carcinoma has been reported only in six cases until now. This report deals with a seventh case characterized by the unique finding of comedo-like features evocative of large cell ductal breast carcinoma within an otherwise typical in situ apocrine carcinoma. This is characterized by spiral-shaped foci of epithelial proliferation with decapitation secretion and central masses of necrotic debris.

Biomarkers to assess the genetic damage induced by alcohol abuse in human lymphocytes.

Alcohol abuse is a major risk factor for cancer of the upper alimentary tract, the upper respiratory tract, and liver. Chromosome damage is used as early effect biomarker in the surveillance of human exposure to genotoxic carcinogens. In the present study, two genetic markers, namely chromosome aberrations (CAs) and micronuclei (MN), were used to evaluate genetic damage in peripheral lymphocytes from 20 alcoholics, 20 abstinent alcoholics, and 20 controls.
