Intralesional ultrasound-guided combined treatment with triamcinolone plus lincomycin in hidradenitis suppurativa: A pilot study.

Hidradenitis suppurativa (HS) is a chronic, inflammatory, disease of the hair follicle. Intralesional corticosteroid treatment in HS patients has been reported, and while several data described this route of administration as an efficient delivery system, its efficacy is still debated. The aim of this study was to explore the clinical efficacy and the effect on quality of life (QoL) of an innovative intralesional treatment in HS patients. This was an interventional prospective study. The treatment consisted of two intralesional ultrasound-guided injections of triamcinolone plus lincomycin, at baseline and after 2 weeks. Lesions and QoL were evaluated at baseline and at 4 weeks following intralesional therapy. All clinical variables of 36 HS patients significantly improved after 4 weeks. Mean values of the visual analog scale (VAS) pain decreased from 4.6 to 1.5, P = .027. The Bodily Pain (BP) scale of the Short-Form Health Survey (SF-36) significantly improved from 36.2 at baseline to 53.9 at 4-week follow-up (P < .001). On a scale from 0 to 10, over 90% of the patients gave a satisfaction score of 8 or more. This combination of corticosteroids and antibiotics delivered intralesionally seems to be effective, as it improved both patient- and physician-reported outcomes.

[Conscience clause in end-of-life care.] / Clausola di coscienza e cura nell'assistenza al fine vita.

The article proposes a critical reflection on issues that appeal to the conscience clause as part of end of life care can produce and what can guarantee freedom of conscience, self-determination of those involved and respect for the dignity of the sick person. After a philosophical and normative analysis, the article is organized on the basis of two important documents for discussion: a position paper of Società Italiana di Anestesia Analgesia Rianimazione e Terapia Intensiva (SIAARTI) signed by several scientific societies "Grandi insufficienze d'organo end stage: cure intensive o cure palliative?" and the Design of Law currently being debated "Norme in materia di consenso informato e di disposizioni anticipate di trattamento". In particular, the conscience clause has been discussed in the light of advance care planning (ACP), which represents the instrument to guarantee the shared planning of care and the shared-decision making. In this context, recourse to the clause of conscience brings out critical ethical and deontological issues that the article discusses, using the position paper SIAARTI and the text of law currently being debated, both built on the assumptions of a shared care relationship, where patient has a key-role in medical decisions.

Pathophysiology of Corneal Dystrophies: From Cellular Genetic Alteration to Clinical Findings.

Corneal dystrophies are a heterogeneous group of bilateral, inherited, rare diseases characterized by slowly progressive corneal opacities, that lead to visual impairment. Most of them have an autosomal dominant pattern of inheritance with variable expressivity, but new mutations have been described. Many corneal dystrophies have been genetically characterized and the specific gene mutations identified, such as for the epithelial-stromal TGFBI dystrophies. Current classification systems identified four main groups of corneal dystrophies based on clinical, histologic, and genetic information. Diagnosis is performed during a routine ophthalmic examination that shows typical cellular abnormalities of the corneal epithelium, stroma, or endothelium. Disease progression should be carefully monitored to decide the proper clinical management. The treatment of corneal dystrophies is variable, depending on symptoms, clinical course, severity, and type of dystrophy. Management aimed to reduce symptoms and to improve vision, includes different surgical approaches. Novel cellular and genetic therapeutic approaches are under evaluation. J. Cell.

Histological findings in a failed corneal riboflavin-UVA collagen cross-linking performed for progressive keratoconus.

PURPOSE: To report the histological and immunohistochemical findings in a cornea removed from a patient who had undergone collagen cross-linking (CXL) with riboflavin and ultraviolet-A for progressive keratoconus. CXL was performed following the Siena protocol. Two years post-CXL, a visual acuity impairment in the treated eye secondary to corneal stromal opacity had occurred, together with corneal thinning and flattening. METHODS: The excised cornea was formalin-fixed, paraffin-embedded, and examined microscopically. Deparaffinized 4-µm sections were stained with hematoxylin-eosin and Masson trichrome. Further tissue sections were subjected to immunohistochemical evaluation of CD34 and Ki-67 antigens. RESULTS: Histologically, there was no scar tissue in the failed cornea. The biomicroscopic stromal opacity corresponded microscopically to an acellular area, devoid of keratocytes, and to compaction of the lamellar collagen. Amorphous, weakly eosinophilic interlamellar deposits, extending from the anterior to the posterior two thirds of the stroma, were noted. CONCLUSIONS: CXL is a promising procedure for the treatment of progressive keratoconus with minimal reported side effects. In the present case, we speculate that the short corneal soaking time (15 minutes according to the Siena protocol) may have resulted in inefficient ultraviolet-A blocking, thermal injury, and deeper keratocyte death. Inadequate keratocyte stem cells reservoir could also play a role in individual cases.

Perioperative stress response to carotid endarterectomy: the impact of anesthetic modality.

OBJECTIVE: Surgery for extracranial carotid artery disease has been challenged by carotid angioplasty stenting because the latter is less invasive and avoids surgical trauma. In fact, the magnitude of the perioperative stress response evoked by carotid endarterectomy (CEA) has never been evaluated. Our aim was to determine the degree of surgical trauma caused by CEA and to define differences related to the use of locoregional or general anesthesia. METHODS: We prospectively studied 113 consecutive CEAs performed on 109 patients admitted at a community institutional center. Patients were stratified for demographics and risk factors and operated on under locoregional (LA) or general anesthesia (GA) depending on both the surgeon preference and patient's compliance. Selective carotid shunting was performed for patients who manifested neurologic deficits under LA or had stump pressure values 120 minutes. Three patients experienced an intraoperative neurologic event and had higher post-CACC cortisol values as compared to asymptomatic patients. CONCLUSIONS: Intraoperative surgical stress was higher under LA and was blunted by carotid shunting under both LA and GA. Within 2 hours after surgery the anesthetic modality no longer had any impact on surgical trauma. The stress response to CEA, regardless of the type of anesthesia, was abolished within 24 hours. Intraoperative stress response, namely hypercortisolemia, directly correlated with subclinical and clinical cerebral hypoperfusion/ischemia during CACC. Hence, attenuation of the stress response to CEA might decrease the incidence of cerebral ischemic events.
