Disseminated trichosporonosis with atypical histologic findings in a patient with acute lymphocytic leukemia

We report a case of disseminated Trichosporon asahii in a patient on systemic antifungal therapy who presented with multiple cutaneous nodules suggestive of fungal infection. Histologic features resembled neutrophilic eccrine hidradenitis but staining with periodic acid‐Schiff and Gomori methenamine silver confirmed the clinical diagnosis. This case highlights the importance of maintaining suspicion for trichosporonosis and contextualizing histologic findings within the underlying clinical picture.     

A cut above the rest: Trimming as a painless depilatory

Shaving and other modes of epilation can cause undue anxiety, pain, or skin irritation in children. Here, we present hair trimming as a safe, painless, and cost‐effective alternative for patients with unwanted hair which may be performed indefinitely or until the child is old enough to direct management. In select cases, removing unwanted hair using this technique may facilitate dermatologic surveillance.     

Dysregulated Fas and Bcl-2 expression leading to enhanced apoptosis in T cells of multiple myeloma patients

We have previously reported the presence of activated (HLA-DR+) T cells in multiple myeloma (MM) patients. These cells produce high amounts of interleukin (IL)-2 and interferon (IFN)-gamma and generate a potent antiplasma cell activity after appropriate in vitro stimulation, but they are unable in vivo to hold in check the disease. Activated T cells are highly susceptible to apoptosis, a form of programmed cell death involved in the modulation of immune responses and regulated by molecules such as Fas (CD95) and bcl-2. The aim of this study was to determine the expression of Fas and bcl-2 antigens and the susceptibility to apoptosis in T cells of MM patients. Fas+ cells were significantly higher, whereas bcl-2+ cells were significantly lower in MM patients than in the controls. MM patients with the highest number of HLA-DR+ T cells showed the highest Fas and the lowest bcl-2 expression. Two-color cytofluorometric analysis confirmed in individual cells that HLA-DR+ T cells coexpressed Fas and lacked bcl-2. Susceptibility to apoptosis was then investigated to evaluate the consequence of dysregulated Fas and bcl-2 expression. The percentage of apoptotic cells after incubation in medium alone (spontaneous apoptosis) or in the presence of methylprednisolone (MP) or anti-Fas monoclonal antibody (triggered apoptosis) was significantly higher in MM and mainly restricted to HLA-DR+ T cells. Spontaneous apoptotosis was reverted by exogenous IL-2. In conclusion, MM T cells have a dysregulated expression of Fas and bcl-2 antigens that is associated with an enhanced susceptibility to apoptosis. These data may unravel a novel mechanism by which activated MM T cells are weakened in their ability to exert an effective antitumor activity in vivo.     

Mother and clinician experiences of a trial of a video feedback parent–infant intervention for mothers experiencing difficulties consistent with ‘personality disorder’: A qualitative interview study

Objectives

We explored mothers' and clinicians' experiences of a video feedback intervention adapted for perinatal ‘personality disorder’ (VIPP-PMH) and the acceptability of a randomised controlled trial (RCT) examining its effectiveness.

Design

In-depth qualitative interviews with participants from a two-phase feasibility study of the VIPP-PMH intervention. Participants were mothers experiencing enduring difficulties in managing emotions and relationships, consistent with a ‘personality disorder’, and their 6- to 36-month-old children.

Methods

Forty-four qualitative interviews were conducted, including all nine mothers receiving VIPP-PMH during the pilot phase, 25 of the 34 mothers participating in the RCT (14 allocated to the VIPP-PMH arm and 9 from the control arm), 11 of the 12 clinicians delivering VIPP-PMH and one researcher. Interview data were thematically analysed.

Results

Mothers described feeling motivated to take part in the research and understood the need for randomisation. Research visits were largely experienced positively, with some suggestions for improvement in questionnaire timing and accessibility. Almost all mothers initially felt anxious about being filmed, but reported positive experiences of the intervention, particularly valuing its non-judgemental, positive and child-focussed nature, their supportive relationship with the therapist and the insights they gained on their child.

Conclusions

The findings indicate the likely feasibility and acceptability of undertaking a future definitive RCT of the VIPP-PMH intervention in this population. In designing a future trial, a positive and non-judgemental therapeutic relationship will be important to allay mothers' anxieties about being filmed, and careful consideration should be given to the timing and accessibility of questionnaires used.     

Erythema nodosum arising during everolimus therapy for tuberous sclerosis complex

Indications for everolimus and other drugs within the mammalian target of rapamycin inhibitor class have recently expanded to include tuberous sclerosis complex. Everolimus is generally well tolerated, but it is important for physicians to identify and manage associated cutaneous adverse effects. We report the first case of a child developing erythema nodosum while undergoing everolimus therapy.     

Filling in the gaps on FILS syndrome: A case report and literature review

FILS syndrome (facial dysmorphism, immunodeficiency, livedo, and short stature) is a rare autosomal recessive disorder caused by pathogenic alterations in the POLE gene leading to multisystemic manifestations, including poorly characterized skin findings. We report a child with a homozygous variant, c.100C > T (p.Arg34Cys), in POLE and features consistent with poikiloderma, expanding the dermatologic signs associated with this rare disorder. Additionally, we review reported cases of FILS syndrome, discuss possible pathomechanisms for our patient's presentation, and consider implications for management.     

Effects of two aerobic exercise training protocols on parameters of oxidative stress in the blood and liver of obese rats

We evaluated the effects of moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) protocols on the alterations in oxidative stress parameters caused by a high-fat diet (HFD), in the blood and liver of rats. The HFD enhanced thiobarbituric acid reactive substances (TBA-RS) and protein carbonyl content, while reducing total sulfhydryl content and catalase (CAT) and glutathione peroxidase (GSH-Px) activities in the blood. Both training protocols prevented an increase in TBA-RS and protein carbonyl content, and prevented a reduction in CAT. HIIT protocol enhanced SOD activity. In the liver, HFD didn’t alter TBA-RS, total sulfhydryl content or SOD, but increased protein carbonyl content and CAT and decreased GSH-Px. The exercise protocols prevented the increase in protein carbonyl content and the MICT protocol prevented an alteration in CAT. In conclusion, HFD elicits oxidative stress in the blood and liver and both protocols prevented most of the alterations in the oxidative stress parameters.

Laboratory Aspirin Resistance Reversibility in Diabetic Patients: a Pilot Study Using Different Pharmaceutical Formulations

Purpose

Aspirin resistance occurs most frequently in diabetic patients and is associated with poor prognosis. The purpose of this study was to evaluate the prevalence of aspirin resistance in a cohort of diabetic patients and whether it can be reversed using more bioavailable aspirin formulations.

Methods

Platelets function of 163 diabetic patients taking acetyl salicylic acid (ASA) 100 mg daily has been evaluated with PFA100 and VerifyNow. Patients found resistant by at least one test received an infusion of 288 mg of lysine acetylsalicylate (Flectadol®) corresponding to ASA 160 mg. Platelets function was measured again after 1 and 24 h. Patients whose the resistance was reversed received 288 mg of soluble salt of lysine acetylsalicylate (Cardirene 160®) corresponding to ASA160 mg instead of aspirin and their aggregation status was re-evaluated after 1 month of therapy.

Results

Prevalence of aspirin resistance in our population was 18,4 % (30/163). In 27 out of 30 patients (90 %) aspirin resistance was reversed within 24 h from the infusion. 25 out of 27 patients (92 %) were found fully aspirin-sensitive after 1 month of oral therapy with soluble salt; two patients were found with borderline value. No adverse reactions were observed.

Conclusions

A significant number of diabetic patients are resistant to aspirin therapy. A single intravenous dose of lysine acetylsalicylate can reverse the platelet hyper-aggregability and laboratory aspirin resistance in large majority of patients. The efficacy of antiaggregation can be maintained by chronic therapy with an oral drug with a more favourable pharmacokinetic profile.
