Total autologous breast reconstruction with the Kiss Latissimus Dorsi Flap.

INTRODUCTION: Patients presenting breast actinic damage or implant-related complications require an autologous approach to breast reconstruction. However, when they are not good candidates for microsurgical procedures, alternative solutions must be sought. Latissimus dorsi (LD) is a workhorse flap in breast reconstruction, but often the amount of skin and volume achievable are insufficient. Taking inspiration from the Kiss flap concept, the authors hereby describe the "Kiss" LD flap to achieve totally autologous breast reconstruction. PATIENTS AND METHODS: A prospective service evaluation of all patients who underwent breast reconstruction with Kiss LD flap between 2018 and 2020 was performed. Patient demographics and operative variables were recorded, together with early and late complications. Patient satisfaction and quality of life were registered using the latest BREAST-Q reconstruction module, which includes specific LD scales. The questionnaire was administered to patients preoperatively and six months postoperatively. RESULTS: Thirty patients underwent total autologous breast reconstruction with Kiss LD flap. Breast cancer and breast sarcoma resection were followed by reconstruction. The timing of reconstruction was immediate in 3 cases and delayed in 27 cases. No major complications nor total flap loss were registered. BREAST-Q scores postoperatively were significantly higher than the preoperative ones in every domain (p<0.0001) except for the physical well-being of back and shoulder, where the scores differed slightly and non-significantly (p=0.05). CONCLUSIONS: The Kiss LD flap allows to harvest a large amount of skin to restore the breast envelope and a considerable volume to reconstruct the breast mound in a completely autologous procedure.

Outcome following surgery to treat septic peritonitis in 95 cats in the United Kingdom.

OBJECTIVES: To review the cause, management and outcome in cats with septic peritonitis within the United Kingdom (2008 to 2018) and to identify if previously identified prognostic factors were associated with survival in this population. MATERIALS AND METHODS: Clinical records from 10 referral hospitals in United Kingdom were reviewed. Data collected included signalment, clinicopathological data and management techniques. Serum albumin, glucose, lactate and ionised calcium concentration; presence of intraoperative hypotension and correct empirical antibiosis were analysed via logistic regression for association with survival. RESULTS: Ninety-five cats were included. The overall survival rate was 66%. Lethargy (89%) and anorexia (75%) were the most common clinical signs, with abdominal pain and vomiting in 44% and 27% of cases, respectively. Gastro-intestinal leakage was the most common source of contamination. The presence of an abdominal mass on clinical examination was not strongly predictive of the presence of neoplasia on histology and did not confer a worse prognosis. Cats presenting with dehiscence of a previous enterotomy/enterectomy did not have a worse prognosis than those presenting with other aetologies. Intraoperative hypotension (adjusted odds ratio 0.173, 95% confidence intervals 0.034 to 0.866, P=0.033) was associated with non-survival. Cats that survived beyond 1 day postoperatively had an improved likelihood of survival (87.5%). All cats that survived beyond 6 days were successfully discharged. CLINICAL SIGNIFICANCE: This study describes the largest group of cats with septic peritonitis with an overall survival rate of 66%. The presence of an abdominal mass on clinical examination or having dehiscence of a previous gastrointestinal surgery did not confer a worse prognosis.

Steroids and growth factors in oral squamous cell carcinoma: useful source of dental-derived stem cells to develop a steroidogenic model in new clinical strategies.

OBJECTIVE: Head and neck region is involved in a high percentage of malignant lesions, and oral squamous cell carcinoma (OSCC) is undoubtedly the most frequently found, accounting for over 90% of malignant tumors. Hormone receptor overexpression, like Estrogen Receptor (ER), Progesterone Receptor (PR) and Endothelial Growth Factor Receptor (EGFR), and signaling have been related to the pathogenesis of OSCC. For metastasis of OSCC, Cancer Stem Cells (CSCs) undergo epithelial to mesenchymal transition (EMT) under the influence of growth factors, cytokines, and regulation of cadherins from the tumor's microenvironment. In this context, the stem cells may become a potential therapeutic target for OSCC through modulation of cytokines and RAS pathway, which is involved in intracell signal transduction. The objective of this study was to suggest an experimental steroidogenic model for OSCC in translational research. PATIENTS AND METHODS: Dental-derived Stem Cells (D-dSCs) have been obtained from apical papilla tissue that surrounds the developing tooth of healthy donors and cultured in vitro. The cells have been exposed to different concentrations of Estradiol (E2 - 10 nM and 40 nM) in order to verify their response. The number of cells and cell viability has been evaluated up to 96 hours of treatment. RESULTS: The results showed that cell growth was increased under estradiol treatments compared with cells maintained without estradiol. Moreover, no significant difference in cell death levels was detected among treatments. CONCLUSIONS: This work underlines as D-dSCs could represent a useful steroidogenic model for the development of the target and gene therapies in OSCC.

Hidradenoma nodular maligno / Malignant nodular hydradenoma

RESUMEN El Hidradenoma nodular maligno o Hidradenocarcinoma es un tumor poco frecuente, derivado de las glándulas sudoríparas ecrinas. Puede surgir de novo o por la transformación de su contraparte benigna. Estos tumores son de crecimiento lento, comportamiento agresivo, con alta incidencia de recurrencias y posibilidad de metástasis. Su prevalencia es en la población adulta, y su pronóstico, incierto. El tratamiento de elección de estos tumores es la escisión quirúrgica con márgenes amplios.

ABSTRACT The Malignant nodular Hydradenoma or Hydradenocarcinoma is a rare tumor, derived from the eccrine sweat glands, may arise de novo or by the transformation of its benign counterpart. These tumors are slow growing, aggressive behavior, with a high incidence of recurrences and the possibility of metastasis; its prevalence being in the adult population, and its prognosis is uncertain. The treatment of choice for these tumors is surgical excision with wide margins.

Successful endovascular treatment of a recurrent giant celiac artery aneurysm.

Visceral artery aneurysms are very rare and aneurysms of the celiac trunk are the rarest ones: they are in most cases asymptomatic and their detection is frequently incidental. In this article we report the case of a man affected by severe abdominal pain with a huge aneurysm of the celiac trunk, first successfully treated with coil embolization, but, after 10 months, another endovascular embolization was required for deployment of the metallic coils previously released, ahead into the fund of the sac with recanalization of the aneurysm. A second endovascular treatment was performed with other coils and Amplatzer-Plug. The high risk of rupture makes treatment of such aneurysms mandatory and surgery is still considered the gold standard therapy of VAA, but, due to its high morbidity and mortality risks, in the last years, it has been widely replaced by endovascular embolization. An effective endovascular embolization requires not only the complete filling of the aneurysmal sac, but also the complete vascular exclusion of its in-flow and out-flow tracts, to reduce the risk of its anterograde or retrograde reperfusion.

Treatment of Severe Gynecomastia After Massive Weight Loss: Analysis of Long-Term Outcomes Measured with the Italian Version of the BODY-Q.

INTRODUCTION: The objectives of this study are: (1) comparison of long-term outcomes after correction of severe gynecomastia using different techniques; (2) apply the Italian version of the BODY-Q; (3) present the role of intercostal perforator flap (ICAP) after massive weight loss for correction of severe gynecomastia. MATERIALS AND METHODS: Between January 2008 and March 2016, we performed surgical correction of bilateral severe gynecomastia in 80 men (160 breasts) following massive weight loss. Patients answered the Italian version of BODY-Q postoperative module. All patients had experienced substantial weight loss (> 30 kg), presented with bilateral severe tissue ptosis of the breast, follow-up of almost 2 years and had a good understanding of the Italian language, and signed consents were included in the study. The sample was studied about age, BMI, comorbidity, bariatric surgical procedure, follow-up, type of post-bariatric surgical procedure, complications and secondary procedures. RESULTS: We performed 487 severe gynecomastia corrections from 2008 to 2016; 80 patients adhered to the inclusion criteria and formed our study group. This cross-sectional study compared three cohorts: 52 access using a circumareolar scar, 18 with an inframammary fold scar, 10 with an inframammary fold scar using intercostal perforator flaps. There were 16 secondary procedures in group one, 2 in group two and 1 in group three. We compared the secondary procedures of group 1 with the other groups, and we obtained a significant difference with a P = 0.04. The mean patient age was 36.5 years, and the average body mass index was 27.5 kg/m2 at the time of surgical correction of gynecomastia. From the BODY-Q analysis, the group of patients undergoing adenomammectomy with inframammary fold scar using intercostal perforator flaps has achieved significantly better results regarding the satisfaction with chest, psychosocial function, satisfaction with outcome and better body image. CONCLUSIONS: This is the first study that used the BODY-Q to analyze the correction of severe gynecomastia following massive weight loss with long-term results. The use of this patient-reported outcome measure underlined that the intercostal artery perforator flap, used in the correction of severe gynecomastia following massive weight loss, is a safe and effective technique with good outcomes and high patient satisfaction.

Síndrome de Stewart-Treves / Stewart-Treves Syndrome

El síndrome de Stewart-Treves es un angiosarcoma cutáneo, poco frecuente, que se produce en pacientes con linfedema crónico. Se describe clásicamente luego de realizar mastectomía radical con vaciamiento ganglionar y/o radioterapia. Su mortalidad es elevada. Comunicamos el caso de una paciente de 76 años de edad, sometida a mastectomía radical con vaciamiento ganglionar axilar, seguido de quimioterapia y radioterapia. Consulta 13 años después por dolor intenso y lesión tumoral exofitica, ulcerada, angiomatosa, sangrante y maloliente en cara anterior del brazo izquierdo. Presentaba edema del miembro de varios años de evolución. Luego de realizar biopsia por punch de la lesión, los resultados histopatológicos resultaron compatibles con linfangiosarcoma. La familia junto con el servicio de Cirugía decide realizar la extirpación del tumor, con conservación del miembro. Falleció luego de once meses de realizado el diagnóstico de síndrome de Stewart-Treves, en nuestro Servicio.

The Stewart-Treves Syndrome is a rare cutaneous angiosarcoma, that occurs in patients with chronic lymphedema. It is classically described after performing radical mastectomy with lymph node dissection and/or radiation therapy. Its mortality is high. We have reported the case of a 76 years old patient, who underwent radical mastectomy with axillary lymph node dissection, followed by chemotherapy and radiotherapy. She came 13 years later with an intense pain and exophytic, ulcerated, angiomatous, bleeding and smelly tumor injury in front side of the left arm. She had an edema of the left upper limb with several years of evolution. After performing punch biopsy of the lesion the histopathological results were compatible with lymphangiosarcoma. The family, jointly with the surgery service decided to remove the tumor with limb preservation. She died 11 months after the diagnosis of Stewart-Treves syndrome, performed in our department.

Occult HBV infection in the oncohematological setting.

INTRODUCTION: Occult hepatitis B infection (OBI), a virological condition characterized by a low release of Hepatitis B Virus (HBV) from liver cells and low HBV-DNA levels in serum and/or liver tissue of HBsAg-negative subjects, may reactivate in oncohematological patients undergoing immunosuppression by aggressive chemotherapy or hematopoietic stem cell transplantation. The entity of OBI reactivation varies from an increase in HBV replication without liver damage to an active HBV replication followed by liver cell necrosis, frequently severe and in some cases life threatening. Because of a possible severe outcome associated with OBI reactivation (hepatic failure or death due to the discontinuation of chemotherapy), prophylaxis with anti-HBV nucleot(s)ide analogues is recommended in relation to the foreseeable degree of immunosuppression. MATERIALS AND METHODS: This review article focuses on the clinical impact of OBI in the oncohematological setting and is addressed to all health care workers having in care oncohematological patients or involved in the treatment of HBV infection and OBI prophylaxis. CONCLUSION: International guidelines have indicated lamivudine prophylaxis in hematopoietic stem cell transplantation and when high-dose corticosteroids or anti-CD20 or anti-CD52 monoclonal antibodies are used. Entecavir or tenofovir should replace lamivudine for patients with advanced liver diseases for whom reactivation of OBI may be life threatening. When anti-CD20 or anti-CD52 sparing schedules or other non-aggressive chemotherapies are used, monitoring may be indicated, but very early treatment with highly effective antiviral drugs (entecavir or tenofovir) should be administered once a reactivation of OBI has occurred.

Multi-functional flow cytometry analysis of CD4+ T cells as an immune biomarker for latent tuberculosis status in patients treated with tumour necrosis factor (TNF) antagonists.

Although monitoring tuberculosis (TB) infection during long-term treatment with tumour necrosis factor (TNF) antagonists is of great importance, no monitoring strategy has yet proved successful. Indeed, even the newly proposed interferon-gamma release assays (IGRAs) are known to produce dynamic changes in IFN-γ plasma levels, making them unreliable indicators of patients' pathological/clinical status. We used intracellular cytokine flow cytometry (ICCFC) to investigate the performance of multi-functional CD4(+) T cells producing IFN-γ, interleukin (IL)-2 and/or TNF in response to Mycobacterium tuberculosis-specific antigens in subjects treated with TNF antagonists. Patients were classified into three groups based on their TB status before commencement of treatment and on IFN-γ level fluctuations evaluated by IGRA during a 36-month follow-up period. The cytokine profile of M. tuberculosis-specific CD4(+) T cells showed that latent tuberculosis infection (LTBI) subjects had a higher frequency of double-positive IFN-γ(+) IL-2(+) CD4(+) T cells and triple-positive IFN-γ(+) IL-2(+) TNF(+) CD4(+) T cells compared to those without LTBI, who showed IFN-γ-level fluctuations over time. In contrast, this latter group of patients showed similar proportions of cells producing IFN-γ alone, IL-2 alone and IL-2 in combination with TNF in response to M. tuberculosis-specific antigens. It therefore appears that patients with and without LTBI infection are characterized by different intracellular cytokine profiles. This is the first study evaluating ICCFC in patients treated with TNF antagonists, and suggests that multi-functional analysis of CD4(+) T cells could be useful for ruling out TB infection in patients classified at screening as LTBI-negative but who show IGRA fluctuations under long-term TNF antagonist treatment.

5-Iodo-2-aminoindan (5-IAI): chemistry, pharmacology, and toxicology of a research chemical producing MDMA-like effects.

In 2010, an internet snapshot of EMCDDA anticipated the presence of 5-iodo-2-aminoindan (5-IAI) within the recreational drug market. In 2011, this compound, a psychoactive derivative of 2-aminoindane, was identified in recreational products sold in the United Kingdom. 5-IAI is a rigid analogue of p-iodoamphetamine producing MDMA-like effects. The aim of this paper is to summarize the clinical, pharmacological, and toxicological information about this new potential drug of abuse.

[Evaluation in vitro of the cardiotoxic effects of 5-fluorouracil for the prevention of cardiovascular damage in health workers occupationally exposed]. / Valutazione in vitro degli effetti cardiotossici da 5-fluorouracile per la prevenzione dei danni cardiovascolari negli operatori sanitari professionalmente esposti.

The occupational exposure to antineoplastic drugs in health care workers determines a risk of absorption through inhalation of vapors or skin contact with drops. Even if many data confirm the cardiotoxicity of anthracyclines, is not clear the evidence of cytotoxicity of 5-Fluorouracil, thoug in a percent of patients receiving this chemotherapy, there is the presence of heart pain, aspecific ECG disorders and induction of coronary disease. This experimental study wants to analyze on the H9c2 cardiomyocyte cell model the effects of 5-Fluorouracil, commonly used in hospital realities of the South Italy, for the prevention of the possible cardiovascular damage in workers occupationally exposed.

Suboptimal response to GnRHa long protocol is associated with a common LH polymorphism.

The aim of this observational preliminary trial was to estimate the association between the most common polymorphism of LH (LH-beta variant: v-betaLH), with different profiles of ovarian response to recombinant human FSH (rhFSH). A total of 60 normogonadotrophic patients undergoing a gonadotrophin-releasing hormone analogue long down-regulation protocol followed by stimulation with recombinant human FSH (rhFSH) for IVF/intracytoplasmic sperm injection, and in whom at least five oocytes were retrieved were retrospectively included. On the basis of the total rhFSH consumption, patients were divided into three groups: Group A: 22 women requiring a cumulative dose of rhFSH >3500 IU; Group B: 15 patients requiring 2000-3500 IU; Group C (control): 23 women requiring <2000 IU. The presence of v-betaLH was evaluated using specific immunoassays. Peak oestradiol concentrations were significantly lower in Group A when compared with both groups B (P < 0.05) and C (P < 0.001). Group A had a significantly lower (P < 0.05) number of oocytes retrieved (7.3 +/- 1.5, 11.7 +/- 2.4 and 14.7 +/- 4.1 in the three groups, respectively). Seven carriers (31.8%) of v-betaLH were found in Group A, whereas only one variant (6.7%) was observed in Group B; no variant was detected in Group C. These preliminary results suggest that v-betaLH is more frequent in women with ovarian resistance to rhFSH.

Antioxidant status and purine bases in carotid artery plaque.

Free radical excess and oxidative stress are implicated in the formation and progression of atherosclerotic plaque through actions on susceptible vascular cells, such as by activating xanthine oxidase. Purine bases and other antioxidant compounds could play important protective roles in atherogenesis, as could nonenzymatic low molecular weight thiol defenses, not previously evaluated in carotid artery plaque. Therefore, we measured purine catabolites (hypoxanthine, xanthine, uric acid, allantoin) and antioxidant compounds (total sulphydryl groups, homocysteine, cysteine, and glutathione) in advanced carotid artery plaque and found a high ratio of allantoin to uric acid, suggesting a ongoing local oxidative stress.

Hominoid-specific SPANXA/D genes demonstrate differential expression in individuals and protein localization to a distinct nuclear envelope domain during spermatid morphogenesis.

Human sperm protein associated with the nucleus on the X chromosome consists of a five-member gene family (SPANXA1, SPANXA2, SPANXB, SPANXC and SPANXD) clustered at Xq27.1. Evolved from an ancestral SPANX-N gene family (at Xq27 and Xp11) present in all primates as well as in rats and mice, the SPANXA/D family is present only in humans, bonobos, chimpanzees and gorillas. Among hominoid-specific genes, the SPANXA/D gene family is considered to be undergoing rapid positive selection in its coding region. In this study, RT-PCR of human testis mRNA from individuals showed that, although all SPANXA/D genes are expressed in humans, differences are evident. In particular, SPANXC is expressed only in a subset of men. The SPANXa/d protein localized to the nuclear envelope of round, condensing and elongating spermatids, specifically to regions that do not underlie the developing acrosome. During spermiogenesis, the SPANXa/d-positive domain migrated into the base of the head as the redundant nuclear envelope that protrudes into the residual cytoplasm. Post-testicular modification of the SPANXa/d proteins was noted, as were PEST (proline, glutamic acid, serine, and threonine rich regions) domains. It is concluded that the duplication of the SPANX-N gene family that occurred 6-11 MYA resulted in a new gene family, SPANXA/D, that plays a role during spermiogenesis. The SPANXa/d gene products are among the few examples of X-linked nuclear proteins expressed following meiosis. Their localization to non-acrosomal domains of the nuclear envelope adjacent to regions of euchromatin and their redistribution to the redundant nuclear envelope during spermiogenesis provide a biomarker for the redundant nuclear envelope of spermatids and spermatozoa.

An unusual association of malignant melanoma and small cell lung cancer: case report. An eleven-year-follow-up.

The authors report the case of a patient affected by malignant melanoma and small cell lung cancer. After having underlined the rareness of this pathological association, reviewing the most recent literature, the description of the clinical case aims at opening a discussion on how the surgical treatment performed, associated to chemotherapy, brought to an unhoped-for success, also helped by an unexpected combination of events that were absolutely out of any protocol. Eleven years later, at the present follow-up, the patient shows a complete remission of both diseases.

[Is the Lauren classification an independent parameter for the prognostic evaluation of surgically treated gastric cancer patients? Analysis of a case series]. / La classificazione di Lauren può essere considerata un parametro indipendente per la valutazione prognostica di pazienti operati per cancro gastrico? Analisi di una casistica.

The Authors highlight the efficacy of the Lauren's classification in 28 surgically treated gastric cancer patients. Lauren's classification allows a prognostic evaluation corresponding to the effective gastric cancer natural history. Present histo-morphological classification criteria appear not to coincide with the clinical evolution; as a matter of fact over- or understaging is possible in gastric cancer patients. 64,28% of the Lauren's classification intestinal type patients survive after a four year follow up vs. 42,85% of the diffuse type patients. The Authors discuss about new biomolecular knowledge in gastric cancer oncogenesis.
