The 3D-printed boluses were used during the radiation therapy of the chest wall in six patients with breast cancer after modified radical mastectomy (MRM). We measured the in-vivo skin doses while both conventional and 3D-printed boluses were placed on the chest wall and compared the mean doses delivered to the ipsilateral lung and the heart. The homogeneity and conformity of the dose distribution in the chest wall for both types of boluses were also evaluated. The uniformity index on the chest skin was improved when the 3D-printed boluses were used, with the overall average skin dose being closer to the prescribed one in the former case (-0...

Nipple-sparing mastectomy (NSM) offers improved cosmesis for women undergoing mastectomy; however, there is increased risk for complications with this technique. We sought to determine if standard anatomic measurements could be used to predict complications of NSM. We performed a retrospective review of NSM for which anthropometric measurements of sternal notch to nipple distance, base width, and inframammary fold to nipple distance were available, and compared outcomes by anatomic measurements. We identified 102 cases of NSM with measurements available for study performed in 55 patients...

Melanoma is the most aggressive skin malignancy with a high rate of mortality and is frequently refractory to many therapeutics, thus demanding the discovery of novel effective anti-melanoma agents. Diphenhydramine (DPH) is an H1 histamine receptor antagonist and a relatively safe drug. Previous studies have revealed the in vitro cytotoxicity of DPH against melanoma cells, but the mechanisms involved concerning its cytotoxicity and the in vivo anti-melanoma effect remain unknown. We herein present the first evidence supporting that DPH is selectively proapoptotic for a panel of melanoma cell lines irrespective of BRAFV600E status while sparing normal melanocytes...

Intravascular large B-cell lymphoma is an extremely rare extranodal lymphoma that proliferates in the lumen of the blood vessels while sparing the organ parenchyma. It usually presents with CNS and skin involvement. A 65-year-old Caucasian female presented with fevers and chills of 3-4 months' duration. Bone marrow biopsy done 3 months prior showed no significant myelodysplasia or lymphoid aggregates. The patient later died due to multiorgan failure. A bone marrow biopsy showed 20-30% CD5+ B cells consistent with infiltrative large B-cell lymphoma...

AIM: There is firm evidence of a relation between type 2 diabetes (T2DM) and increased risks of cancer at various sites, but it is still unclear how different antihyperglycaemic therapies modify site-specific cancer risks. The aim of this study was to provide a complete characterization of all possible associations between individual T2DM therapies, statin use and site-specific cancers in the Austrian population. METHODS: Medical claims data of 1 847 051 patients with hospital stays during 2006-2007 were used to estimate age- and sex-dependent co-occurrences of site-specific cancer diagnoses and treatment with specific glucose-lowering drugs and statins...

Although a glucocorticoid (GC)-sparing strategy is needed for patients with giant cell arteritis (GCA) suffering from refractory disease or serious treatment-related complications, evidence of efficacy in this setting of immunosuppressive drugs and biotherapies is lacking. Herein, we evaluated the GC-sparing effects and tolerability of addition of dapsone (DDS) to prednisone therapy in patients with GCA. We retrospectively assessed data on 18 GCA patients who received DDS as a first-line treatment (DDS-1 group) and 52 patients who received it as a second- or third-line treatment for refractory GCA, with or without excessive GC-related toxicity (DDS-2 group)...

BACKGROUND: Changes in breast sensation after reconstruction are expected. Return of breast sensation after reconstruction and whether nipple-sparing mastectomy offers a substantial benefit in terms of sensation has been inconsistently documented in the literature. We conducted the current study using the pressure-specified sensory device to quantify postoperative breast sensation in patients undergoing nipple-sparing versus non-nipple-sparing mastectomy. METHODS: Consecutive adult women who underwent nipple-sparing (NSM) and non-NSM (NNSM) and were at least 18 months postreconstruction were included...

In this study, non-aqueous microemulsions were developed because of the challenges associated with finding pharmaceutically acceptable solvents for topical delivery of drugs sparingly soluble in water. The formulation irritation potential and ability to modulate the penetration of lipophilic compounds (progesterone, α-tocopherol, and lycopene) of interest for topical treatment/prevention of skin disorders were evaluated and compared to solutions and aqueous microemulsions of similar composition. The microemulsions (ME) were developed with BRIJ, vitamin E-TPGS, and ethanol as surfactant-co-surfactant blend and tributyrin, isopropyl myristate, and oleic acid as oil phase...

Pityriasis rubra pilaris (PRP) is a rare, chronic inflammatory skin disorder characterized by the presence of small follicular hyperkeratotic papules that coalesce into yellow-pink (salmon-colored) patches, usually beginning at the head and neck and often resulting in generalized erythroderma(1) . Other main clinical features are "islands" of sparing within the affected skin, palmoplantar keratoderma, nail dystrophy, oral involvement and eventually ectropion. The age of onset has a peak between 50 and 70 years but a juvenile presentation is not uncommon...

BACKGROUND: When the inframammary fold (IMF) is excised in mastectomy procedures for oncologic reasons, it must be recreated to restore a natural breast shape. Despite refinements in surgical techniques, postoperative loss of a well-defined IMF can occur. This study aimed to assess the outcomes of IMF recreation after two-stage, implant-based breast reconstruction. METHODS: We retrospectively reviewed 75 consecutive patients who underwent unilateral, two-stage, implant-based breast reconstruction between 2013 and 2015 at the authors' institution...

Paraneoplastic pemphigus (PNP) is a fatal autoimmune blistering disease associated with an underlying malignancy. It is a newly recognized blistering disease, which was first recognized in 1990 by Dr Anhalt who described an atypical pemphigus with associated neoplasia. In 2001, Nguyen proposed the term paraneoplastic autoimmune multiorgan syndrome because of the recognition that the condition affects multiple organ systems. PNP presents most frequently between 45 and 70 years old, but it also occurs in children and adolescents...

Lipoedema is a chronic progressive adipose disorder that affects mainly women and presents as symmetrical enlargement of the buttocks and legs. It is commonly misdiagnosed as obesity or lymphoedema, but careful assessment will reveal a disproportionate enlargement below the waist which is resistant to dieting, sparing of the feet, legs are tender or painful to touch and bruise easily, there is occasional orthostatic oedema, and there is often significant psychological morbidity. Lipoedema is a oestrogen-regulated condition with onset around puberty in 78% of women, and there is often a strong family history...

The efficacy of allogeneic hematopoietic stem cell transplantation for hematologic malignancies is limited by the difficulty in suppressing graft-versus-host disease (GVHD) without compromising graft-versus-tumor (GVT) effects. We previously showed that RAS/MEK/ERK signaling depends on memory differentiation in human T cells, which confers susceptibility to selective inhibition of naive T cells. Actually, antineoplastic MEK inhibitors selectively suppress alloreactive T cells, sparing virus-specific T cells in vitro...

BACKGROUND: While nipple-sparing mastectomy (NSM) is gaining acceptance for risk reduction and for treatment of early stage breast cancer, node-positive disease remains a relative contraindication. Our aim was to evaluate the use and outcomes of NSM in node-positive breast cancer patients. METHODS: We identified 240 cancers in 226 patients (14 bilateral) scheduled for NSM and operated on between 1/2009 and 6/2014. We compared outcomes for 58 node-positive vs 182 node-negative patients...

BACKGROUND: The standard of care for lower extremity soft tissue sarcoma (STS) is limb-sparing surgery. A small subset of these patients will require concomitant vascular reconstruction to ensure adequate resection and to preserve limb viability and function. The aim of this study was to evaluate outcomes in these patients with respect to wound healing and postoperative functional status. METHODS: Outcomes for a total of 154 patients treated for malignant lower extremity STS during an 8-year period between 2005 and 2013 were entered in a prospective registry...

The NIAID Radiation and Nuclear Countermeasures Program is developing medical agents to mitigate the acute and delayed effects of radiation that may occur from a radionuclear attack or accident. To date, most such medical countermeasures have been developed for single organ injuries. Angiotensin converting enzyme (ACE) inhibitors have been used to mitigate radiation-induced lung, skin, brain, and renal injuries in rats. ACE inhibitors have also been reported to decrease normal tissue complication in radiation oncology patients...

BACKGROUND: Highly migrated intracanal disk herniation is not among the exclusion criteria of the interlaminar microendoscopic diskectomy (MED) procedure. The goal of this prospective, randomized, controlled study was to compare the effect of the size of the skin incision and the method of handling the multifidus muscle on the results of the interlaminar MED procedure versus conventional microdiskectomy in retrieving highly migrated intracanal disk herniations. METHODS: Seventy-three patients with highly migrated intracanal lumbar disk herniations treated with either minimal incision, multifidus-sparing MED or conventional microdiskectomy were observed for 2 years...

With the advent of the skin sparing mastectomy, immediate breast reconstruction with placement of the definitive prosthesis at the time of mastectomy is possible. The question remains: does single-stage prosthetic reconstruction result in greater numbers of complications or rates of re-operation, compared to two-stage tissue expander reconstruction? A retrospective cohort study of a single centre?s experience with these techniques was carried out. From 2004 to 2012, 54 cases of immediate breast reconstruction with implant were identified, and 108 cases of immediate breast reconstruction using a tissue expander were identified...
