Three-Flap Mastopexy with Reduction or Augmentation.

BACKGROUND: Many authors have studied breast ptosis and made contributions to the search for a procedure that allows its correction with long-lasting results and minimal scars. Collective evolution has allowed us to reach the point where we are today and will allow us to continue improving techniques in the future. OBJECTIVES: The mastopexy procedure that we have used for the last 11 years, resulting from our surgical practice and countless observations at conferences, is a versatile procedure, applicable to different types of breasts and mastopexies with and without reduction or augmentation. METHODS: Analysis and the clinical review of the patients and the records of the mastopexy cases that we operated on using the technique from January 2009 to March, 2020, are presented here. Using a periareolar approach for grade I ptosis and an inverted "T" approach for more severe ptosis, the excess skin is removed, and three flaps of breast tissue, superior, medial and lateral, are carved. A retromammary dissection is performed to anchor the end of the flaps, medial and lateral, to the pectoral aponeurosis, followed by invagination of these flaps to concentrate the breast tissue in the upper and central area of the breast. Closure of the wound is then performed, transforming its excess length into a short horizontal one, into the inframammary grove. RESULTS: Sixty-seven female patients, between 36 and 59 years old, underwent this procedure. Complications included hematoma (4%), overcorrection (4%), dehiscence (3.3%), residual ptosis (2.7%), pathological scarring (2.7%) and rotation folds (2%). Maximum follow-up was 8 years 2 months, mean follow-up 2 years 9 months, with satisfactory results for the patients and surgeon. CONCLUSIONS: The mastopexy procedure that we present here is a versatile technique, which can be applied to most cases requiring correction of ptosis. It provides the breast with proper shape, size and location with fewer scars. It is a logical, safe, efficient, reproducible procedure, which is easy to learn.

COVID-19 and the digestive system: protection and management during the SARS-CoV-2 pandemic.

The purpose of this rapid review is to provide an update on the impact of SARS-CoV-2 infection on Gastroenterology and Hepatology departments, our patients, and our new way of working. The gastrointestinal tract and the liver are affected by SARS-CoV-2, especially in patients with immunosuppressive therapies. Patients with liver transplantation should be followed closely. Digestive endoscopy is a high-risk procedure for the transmission of SARS-CoV-2. While the pandemic lasts, we must adapt its indications and promote protective measures for patients and healthcare professionals alike. The COVID-19 pandemic has changed our priorities and the way we work, although we do not know what the repercussions will be after normality is reinstated.

Clinical, epidemiological and treatment failure data among HIV-1 non-B-infected patients in the Spanish AIDS Research Network Cohort.

INTRODUCTION: The prevalence of HIV-1 non-B variants is increasing in Spain, showing a higher number of transmitted drug resistance mutations (TDR) since 2002. This study presents the features of non-B-infected patients enrolled in the cohort of antiretroviral treatment (ART) naïve HIV-infected patients included in the Research Network on HIV/AIDS (CoRIS). METHODS: The study includes a selected group of HIV-1 non-B-infected subjects from 670 subjects with pol sequences collected from 2004 to 2008 in the CoRIS cohort. Epidemiological-clinical-virological data were analyzed since cohort entry until October 2011, considering the presence or absence of treatment failure (TF). RESULTS: Eighty two non-B infected subjects with known HIV-1 variants were selected from 2004 to 2008 in the CoRIS cohort, being mainly female, immigrants, infected by recombinant viruses, and by heterosexual route. They had an intermediate TDR rate (9.4%), a high rate of TF (25.6%), of losses to follow-up (35%), of coinfections (32.9%), and baseline CD4+ counts ≥350cells/mm(3) (61.8%). Non-B subjects with TF showed higher rates of heterosexual infection (85.7% vs. 69.5%, p<0.05), tuberculosis (30.8% vs. 9.1%, p=0.10) and hepatitis C (23.8% vs. 13.9%, p=0.34) coinfections and lower rates of syphilis (0% vs. 21.9%, p<0.05), and had more frequently received first-line ART including protease inhibitors (PIs) than patients without TF (70% vs. 30%, p<0.05). Interestingly, infection with non-B variants reduced the risk of TDR to nucleoside reverse transcriptase inhibitors and increased the risk to PIs. CONCLUSION: HIV-1 non-B-infected patients in Spain had a particular epidemiological and clinical profile that should be considered during their clinical management.

[Microbiological diagnosis of human immunodeficiency virus infection]. / Diagnóstico microbiológico de la infección por el virus de la inmunodeficiencia humana.

This document attempts to update the main tasks and roles of the Clinical Microbiology laboratory in HIV diagnosis and monitoring. The document is divided into three parts. The first deals with HIV diagnosis and how serological testing has changed in the last few years, aiming to improve diagnosis and to minimize missed opportunities for diagnosis. Technological improvements for HIV Viral Load are shown in the second part of the document, which also includes a detailed description of the clinical significance of low-level and very low-level viremia. Finally, the third part of the document deals with resistance to antiretroviral drugs, incorporating clinical indications for integrase and tropism testing, as well as the latest knowledge on minority variants.

[Study of human immunodeficiency virus transmission chains in Andalusia: analysis from baseline antiretroviral resistance sequences]. / Los estudios de resistencias a antirretrovirales como herramienta para el análisis de los clusters de transmisión del virus de la inmunodeficiencia humana.

INTRODUCTION AND OBJECTIVE: Protease and reverse transcriptase HIV-1 sequences provide useful information for patient clinical management, as well as information on resistance to antiretrovirals. The aim of this study is to evaluate transmission events, transmitted drug resistance, and to georeference subtypes among newly diagnosed patients referred to our center. METHODS: A study was conducted on 693 patients diagnosed between 2005 and 2012 in Southern Spain. Protease and reverse transcriptase sequences were obtained for resistance to cART analysis with Trugene(®) HIV Genotyping Kit (Siemens, NAD). MEGA 5.2, Neighbor-Joining, ArcGIS and REGA were used for subsequent analysis. RESULTS: The results showed 298 patients clustered into 77 different transmission events. Most of the clusters were formed by pairs (n=49), of men having sex with men (n=26), Spanish (n=37), and below 45 years of age (73.5%). Urban areas from Granada, and the coastal areas of Almeria and Granada showed the greatest subtype heterogeneity. Five clusters were formed by more than 10 patients, and 15 clusters had transmitted drug resistance. CONCLUSIONS: The study data demonstrate how the phylogenetic characterization of transmission clusters is a powerful tool to monitor the spread of HIV, and may contribute to design correct preventive measures to minimize it.

Quantification of viral loads lower than 50 copies per milliliter by use of the Cobas AmpliPrep/Cobas TaqMan HIV-1 test, version 2.0, can predict the likelihood of subsequent virological rebound to >50 copies per milliliter.

After 1 year of follow-up, patients on HAART with a baseline viral load (VL) of <20 copies/ml showed significantly lower odds of virological rebound to two consecutive VLs of >50 copies/ml than those with baseline VLs of 20 to 39 and 40 to 49 (P < 0.001). The time to virological rebound was also significantly shorter (P < 0.001) for the groups with baseline VLs of 20 to 39 and 40 to 49.

[Update on hepatitis C therapy. New drugs, treatment response monitoring and emergence of resistance]. / Actualización en la terapia de la hepatitis C. Nuevos fármacos, monitorización de la respuesta y resistencias.

The development of novel direct antiviral agents (DAAs) against hepatitis C virus (HCV) has represented a breakthrough in the treatment of chronic hepatitis C. Telaprevir and boceprevir are the first two protease inhibitor (PI) DAAs to be approved for combination therapy with pegylated interferon (PEG-IFN) and ribavirin (RBV). In genotype 1 monoinfected patients, triple PI therapy has increased sustained viral response (SVR) rates by approximately 30% compared with conventional combination therapy. The introduction of these drugs into clinical practice will modify the timing of monitoring parameters in diagnostic laboratories, especially with regard to stopping rules and to faster delivery of results. In the near future, new DAAs, directed against different targets of the HCV cycle (polymerase inhibitors, viral replication complex inhibitors and cyclophilin inhibitors), which are currently in various stages of clinical development, will be available. Some of these DAAs have already reached advanced phases of development, both in combination with PEG-IFN and RBV and in interferon-free therapy, with very high rates of SVR.

[Low prevalence of hepatitis B virus primary drug resistance in Southern Spain]. / Baja prevalencia de resistencias primarias frente al virus de la hepatitis B en el sur de España.

INTRODUCTION: To know the prevalence of primary resistance in chronic hepatitis B naïve patients is essential to decide on the need of routine laboratory testing. PATIENTS AND METHODS: The genetic sequence of the HBV polymerase from 105naïve patients was analysed. RESULTS: rtV173L, a lamivudine compensatory mutation, was detected in two patients (1.9%), rtI233V in one patient, and another one carried the sG145R vaccine escape mutation. CONCLUSION: Our study shows that studying HBV resistance in naïve patients should not be recommended in the routine laboratory setting, for the time being.

Mpox Infection and Sexually Transmitted Infections: A Cross-Sectional Study from a Secondary Hospital in the May-September 2022 International Outbreak.

The aims of this study were to describe the characteristics of patients infected by mpox in our setting, to determine the prevalence of mpox in samples that are classically used for diagnosing sexually transmitted infections (STIs) such as anal, urethral, pharyngeal, and urine, and to assess the prevalence of coinfection with STIs in the same samples. A cross-sectional study was conducted, collecting all confirmed cases of mpox between June and July 2022 using polymerase chain reaction. Sociodemographic data, HIV and other STI status, and prevalence of mpox and STIs in urethral, anal, pharyngeal, or urine samples were collected. Data from 22 patients were extracted, all of whom were men who have sex with men (MSM) and 54.5% were previously HIV positive. The median age was 43 years. All the skin samples were positive for mpox, followed by anal samples (n = 10, 45.5%). Mpox was isolated in 2 or more samples simultaneously in 12 (54%) cases. Nine (41%) patients were positive for an STI and four of them had more than one STIs (18.2%). Human mpox has been epidemiologically significant among MSM. Mpox should be investigated not only in skin lesions but also in samples classically used for STIs. Mpox, such as other STIs, shares ways of transmission and coinfection may be underdiagnosed.

Morphological and immunophenotypical differences between chronic periodontitis and peri-implantitis - a cross-sectional study.

PURPOSE: To examine differences in morphology and in immunophenotype subsets between chronic periodontitis (CP) and peri-implantitis (P-I) lesions and to test the diagnostic agreement (CP vs P-I) among three independent observers, based on histopathological features. MATERIALS AND METHODS: This observational cross-sectional study included 15 gingival biopsies of CP lesions and 15 biopsies of P-I lesions for double-blinded examination by three independent pathologists. Inflammatory infiltrate intensity was assessed semiquantitatively on a 4-point scale, determining the percentage of lymphocytes, plasma cells, monocytes/macrophages, and granulocytes and the presence/absence of bacterial colonies. Immunohistochemical analyses were performed to verify the inflammatory infiltrate subset data (CD45, CD38, CD68 and myeloperoxidase [MPO]-positive), and number of vessels. Kappa statistic was used to evaluate the degree of diagnostic concordance among examiners. RESULTS: Inflammatory infiltrate was significantly more severe in P-I cases (P = 0.01), which showed a significantly higher percentage of plasma cells (P = 0.004) than in CP cases. Immunohistochemically, the percentage of leukocyte subsets was generally lower in CP (CD38: 32.05%; CD68: 6.45% and MPO: 8.62%) than in P-I (CD38: 61.13%; CD68: 9.09% and MPO: 7.47%) (CD38 P = 0.001, P = 0.955 and P = 0.463, for remaining subsets, respectively; Mann-Whitney U-test). The inter-observer diagnostic agreement was poor or slight (kappa = -0.18 to 0.13). CONCLUSIONS: Despite the significantly more severe general inflammatory infiltrate and plasma cells in P-I cases, it proved difficult to detect reliable differential morphological features based on histopathological images of these CP and P-I soft-tissue samples, obtaining low inter-observer and intra-observer diagnostic agreement. Conflict of interest statement: This investigation was partially supported by Research Groups #CTS-138 and #CTS-583 (Junta de Andalucía, Spain). No conflict of interest.

Experience in real clinical practice with new direct acting antivirals in chronic hepatitis C. / Experiencia en práctica clínica real con los nuevos antivirales de acción directa en hepatitis crónica C.

INTRODUCTION AND OBJECTIVE: Inclusion of direct-acting antivirals into clinical practice in patients with chronic HCV (CHC) has been a milestone in medicine. PATIENTS AND METHODS: Analytical, prospective study, involving 126 patients with chronic HCV treated with direct-acting antivirals. Efficacy and safety of treatment and factors associated with failure treatment were evaluated. RESULTS: Age 54±10. Male (70%). Cirrhosis (60%). Distribution according to genotypes: G1a (31%), G1b (42%); G3 (14%); G4 (13%). Child-Pugh B and C (n=15). Naïve (56%). SVR rate was (87.3%): Child-A (91%), Child-B (75%) and Child-C (60%). The best cure rates were achieved with a 3D/2D±ribavirin (SVR=97.4%;n=39) and sofosbuvir/ledipasvir±ribavirin (RVS=93.1%; n=29) combination. An SVR rate of <90% was achieved with sofosbuvir+simeprevir±ribavirin (SVR=88%, n=25), simeprevir+daclatasvir±ribavirin 73%, n=15). The association of ribavirin to these last three therapeutic options (n=19) improved cure rates (SVR=94.7%, 18/19) compared to its absence (n=39;SVR=77%). Improvement in MELD (40%). Output transplant list (20%). Substitutions associated with resistors NS3: G1a (positions 80K; n=5); G1b and G4 (position 168 and 36; n=4), while for NS5a: G1a (position 30; n=2) and G1b and G3 (position 93; n=3). Variables associated with failure in multivariate analysis (p<0.05): presence of ascites, G3 and ribavirin dosage<600mg/day. DISCUSSION: The presence of genotype 3, ascites or dosage of ribavirin<600mg/day were associated with higher failure rates. The use of ribavirin>600mg/day in cirrhotic G1 or G3, who will be treated with sofosbuvir+simeprevir or daclatasvir is recommended where no baseline resistance test is available.

Case for diagnosis.

Majocchi's granuloma is a persistent supurative folliculitis, associated with a deep granulomatous reaction induced by dermatophytes. There are two clinical forms of Majocchi's granuloma: the superficial form that appears in healthy individuals after localized trauma; and the nodular form, which occurs in inmunocompromised patients. We present a case of nodular Majocchi's granuloma on the forearm of an immunocompetent patient. Microbiological culture and examination of a deep aspiration sample identified Trichophyton rubrum. Collecting a deep sample of tissue is essential in achieving a good diagnostic performance.
