Outcomes of lung and liver transplantation after simultaneous recovery using abdominal normothermic regional perfusion in donors after the circulatory determination of death versus donors after brain death.

Normothermic regional perfusion (NRP) in controlled donation after the circulatory determination of death (cDCD) is a growing preservation technique for abdominal organs that coexists with the rapid recovery of lungs. We aimed to describe the outcomes of lung transplantation (LuTx) and liver transplantation (LiTx) when both grafts are simultaneously recovered from cDCD donors using NRP and compare them with grafts recovered from donation after brain death (DBD) donors. All LuTx and LiTx meeting these criteria during January 2015 to December 2020 in Spain were included in the study. Simultaneous recovery of lungs and livers was undertaken in 227 (17%) donors after cDCD with NRP and 1879 (21%) DBD donors (P < .001). Primary graft dysfunction grade-3 within the first 72 hours was similar in both LuTx groups (14.7% cDCD vs. 10.5% DBD; P = .139). LuTx survival at 1 and 3 years was 79.9% and 66.4% in cDCD vs. 81.9% and 69.7% in DBD (P = .403). The incidence of primary nonfunction and ischemic cholangiopathy was similar in both LiTx groups. Graft survival at 1 and 3 years was 89.7% and 80.8% in cDCD vs. 88.2% and 82.1% in DBD LiTx (P = .669). In conclusion, the simultaneous rapid recovery of lungs and preservation of abdominal organs with NRP in cDCD donors is feasible and offers similar outcomes in both LuTx and LiTx recipients to transplants using DBD grafts.

Country data on AMR in Mexico in the context of community-acquired respiratory tract infections: links between antibiotic susceptibility, local and international antibiotic prescribing guidelines, access to medicine and clinical outcome.

BACKGROUND: Antimicrobial resistance (AMR) is one of the biggest threats to global public health. Selection of resistant bacteria is driven by inappropriate use of antibiotics, amongst other factors. COVID-19 may have exacerbated AMR due to unnecessary antibiotic prescribing. Country-level knowledge is needed to understand options for action. OBJECTIVES: To review AMR in Mexico and initiatives addressing it. Identifying any areas where more information is required will provide a call to action to minimize any further rises in AMR and to improve patient outcomes. METHODS: National AMR initiatives in Mexico, antibiotic use and prescribing, and availability of susceptibility data, particularly the key community-acquired respiratory tract infection (CA-RTI) pathogens Streptococcus pneumoniae and Haemophilus influenzae, were identified. National and international antibiotic prescribing guidelines commonly used in Mexico for specific CA-RTIs (community-acquired pneumonia, acute otitis media and acute bacterial rhinosinusitis) were also reviewed, along with local antibiotic availability. Insights from a local clinician were sought to contextualize this information. CONCLUSIONS: The Mexican national AMR strategy was published in 2018. This comprised similar objectives to the Global Action Plan from the World Health Assembly (2015) and was compulsory, requiring full compliance from members of the National Health System. Historically, antibiotic consumption in Mexico has been high, however, between 2000 and 2015, consumption fell, in sharp contrast to the majority of countries. Mexico lacks a national surveillance network for AMR, however there are several ongoing global surveillance studies providing local antibiotic susceptibility data. International and local antibiotic prescribing guidelines for CA-RTIs are used. A more standardized inclusive approach in developing local guidelines, using up-to-date local surveillance data of isolates from community-acquired infections, could make guideline use more locally relevant. This would pave the way for a higher level of appropriate antibiotic prescribing and improved adherence. This would, in turn, potentially limit AMR development in Mexico and improve patient outcomes.

Topical N-acetylcysteine for the treatment of lamellar ichthyosis: an improved formula.

Topical N-acetylcysteine is gaining recognition as a useful and safe therapy for lamellar ichthyosis. We report a case of inherited lamellar ichthyosis that showed a good response to treatment with a new formula of N-acetylcysteine cream. With this new formula, which is described in the article in a practical manner, the odor of sulfur was minimized and we obtained excellent adherence to treatment.

Impact of pregnancy on women's health-related lifestyle habits: Diet, physical activity, alcohol consumption, and smoking.

OBJECTIVES: To explore health-related lifestyles in women before and during pregnancy, and to determine the potential differences between both and the relevant factors. MATERIALS AND METHODS: A cross-sectional observational study including 348 women with a child <5 years of age was conducted in six health areas. The following variables were recorded: sociodemographic (age, educational level, marital status, social class, type of cohabitation, nationality), health-related habits (physical activity, diet, tobacco use, alcohol consumption), health conditions, and medication intake. RESULTS: Four lifestyle habits were compared between the pre-conception and pregnancy periods: diet, physical activity, and alcohol and tobacco use. The proportion of women who consumed alcohol (42.8 % vs 3.4 %) or smoked (19.3 % vs 12.4 %) was significantly higher before conception (p < 0.01). Conversely, the proportion of inactive women was lower before pregnancy, with 23.3 % (CI95%: 18.7-27.9) formerly classified as active versus 35.3 % (CI95%: 30.2-40.5) (p < 0.01). Similarly, adherence to the Mediterranean diet increased during pregnancy (62.9 % vs 75.0 %; p < 0.01). Furthermore, 53.2 % (CI95%: 47.8-58.5) of women reported a change from non-healthy to healthy in at least one of the evaluated habits. Logistic regression analyses revealed the variables associated with a positive change, which were being national Spanish (OR: 6.9) and experiencing the first pregnancy (OR: 1.8). CONCLUSIONS: The lifestyles of women undergo changes between the pre-gestation and pregnancy periods. However, such variations do not affect all health-related habits similarly. A positive change was observed in diet, alcohol consumption, and smoking habit, whereas pregnancy negatively impacted on physical activity and sedentary behaviours.

Reticular variant of mid-dermal elastolysis.

Mid-dermal elastolysis is a rare disorder characterised by focal loss of elastic tissue in the mid-dermis. Most patients present with lesions of fine wrinkling (type I) or perifollicular papules (type II). The reticular variant (type III) has been described less often in the literature. We report a case of a young woman with type III mid-dermal elastolysis.

Calciphylaxis treated with sodium thiosulfate: report of two cases.

Although traditionally observed in patients with end-stage renal disease and secondary hyperparathyroidism, calciphylaxis has been reported in patients with normal renal and parathyroid function. There is no evidence-based therapy available. The use of sodium thiosulfate (STS) has been increasingly described. Herein we describe two patients who responded well to this treatment.

Pediatric invasive fungal rhinosinusitis.

Pediatric invasive fungal rhinosinusitis (PIFR) is a rapidly progressive, potentially fatal disease. Previous medical literature demonstrates that its early diagnosis significantly reduces the risk of mortality in these patients. This study aims to present an updated clinical algorithm for optimized diagnosis and management of PIFR. A comprehensive review was conducted with only original, full-text articles published in English and Spanish from Cochrane Library, Pub-Med/MEDLINE, Embase, Scopus, and Google Scholar between January 2010 and June 2022. Relevant information was extracted and then integrated to develop a clinical algorithm for a proper diagnosis and management of PIFR.

Rhabdomyolysis following Nuss Procedure: A Prospective Study in Children.

INTRODUCTION: Postoperative rhabdomyolysis (RML) has been documented after several surgical procedures in adults. Musculoskeletal remodeling after Nuss procedure for pectus excavatum (PE) could cause RML. We evaluated the incidence of RML after Nuss procedure in children. METHODS: This study was a prospective study from 2018 to 2021. We enrolled all otherwise healthy patients who underwent PE correction with only one bar. Studied variables included demographic and clinical data, duration of surgery, complications, and length of hospitalization. The patients included underwent serial measurements of serum creatine kinase (CK), troponin I, N terminal pro B-type natriuretic peptide (NT-proBNP), serum creatinine, urea, and glomerular filtration rate at 6 and 48 hours postoperatively, and hospital discharge. RESULTS: Forty-six patients met criteria (40 males/6 females), with a mean age of 15.1 ± 1.4 years. Mean duration of surgery was 74 ± 28 minutes, and length of hospitalization was 4.6 ± 1.6 days. RML was diagnosed in 30.4% of patients at 6 hours, 91.3% at 48 hours, and 21.7% at hospital discharge. Mean preoperative CK value was 181.1 ± 141.6 IU/L, and postoperative values were 863.3 ± 302.6 IU/L at 6 hours, 1,675.2 ± 561 IU/L at 48 hours, and 850 ± 683.7 IU/L at hospital discharge, with statistically significant differences (p = 0.001). High-sensitivity troponin I and NT-proBNP levels increased significantly during the postoperative time (p = 0.001). Renal function remained stable (p = 0.55). CONCLUSION: Nuss technique produces RML without kidney injury in healthy patients. This knowledge should be considered for patients at increased risk of developing acute kidney injury and other complications.

Percutaneous Cryoanalgesia: A New Strategy for Pain Management in Pectus Excavatum Surgery.

INTRODUCTION: In recent years, pain protocols for pectus excavatum (PE) have incorporated cryoanalgesia through thoracoscopic approach. Since 2019, ultrasound-guided percutaneous cryoanalgesia (PCr) has been applied at our institution, either on the same day as the Nuss procedure or 48 hours before surgery. We carried out a preliminary retrospective review of patients with PE in whom PCr prior to surgery was performed at our institution between 2019 and 2021. MATERIALS AND METHODS: Two groups were evaluated: PCr on the same day (PCrSD) and PCr 48 hours before surgery (PCr48). Despite PCr, patients were treated with "patient-controlled analgesia" (PCA) with opioids for at least 24 hours, switching to conventional intravenous analgesia and oral analgesia in the following days. Demographic, clinical-radiological variables, PCA opioid use, pain grade according to the visual analog scale (VAS), and length of stay (LOS) were compared between the groups. A total of 20 patients were included (12 with PCrSD and 8 with PCr48), without significant differences in demographics or clinical-radiological variables. The overall median time of PCr was 65 minutes (55-127), with no differences between the groups. RESULTS: PCr48 group presented with significantly lower median number of hours of continuous PCA (24 vs. 32 hours; p = 0.031), lower median number of rescue boluses (11 vs. 18; p = 0.042), lower median VAS in the early postoperative hours (2 vs. 5.5; p = 0.043), and lower median LOS (3.5 vs. 5 days). CONCLUSION: PCr performed 48 hours prior to surgery is more effective in terms of PCA requirements, VAS, and LOS when compared with cryoanalgesia on the same day.

Influence of the mother's lifestyles on the initiation of breastfeeding: A case-control study.

INTRODUCTION: Breast milk is the optimal food during the first months of life. The main objective was to analyse the factors associated with not initiating breastfeeding in terms of maternal lifestyles, epidemiological characteristics and information on breastfeeding. MATERIAL AND METHOD: Observational analytical study of cases and controls in 6 primary care centres. The sample included women with a child under 5 years, with an estimated necessary sample size of 166 cases (women who did not initiate breastfeeding) and 166 controls (women who began breastfeeding). Sociodemographic and maternal lifestyle variables were measured before and during pregnancy, such as physical activity using the BPAAT questionnaire, diet with the MEDAS-14 questionnaire, and tobacco and alcohol consumption. We assessed the information and opinions about breastfeeding as well as previous experience with it. RESULTS: The study included 348 women (174 cases and 174 controls) with a mean age of 33.4 years (SD, 5.4). The variables independently associated with not initiating breastfeeding were: absence of previous experience with breastfeeding (odds ratio [OR], 12.75), making the decision during pregnancy or delivery (OR, 10.55), not being married or in a partnership (OR, 3.42) and being sedentary for periods of 2 hours or greater/day during pregnancy (OR, 1.77). CONCLUSIONS: In our study, the determining factors associated with not initiating breastfeeding were the lack of previous experience with breastfeeding, the timing of the decision about breastfeeding, and marital status. When it came to lifestyle, only a sedentary lifestyle was associated with not initiating breastfeeding, while dietary or other habits had no influence.

Streptococcus pneumoniae serotypes isolated from the middle ear of Mexican children diagnosed with acute otitis media.

OBJECTIVE: The aim of this study was to identify the etiology and the serotypes of S. pneumoniae (Sp) in Mexican children with acute otitis media (AOM). MATERIALS AND METHODS: The study includessamples frompatientsdiagnosed with AOM at the Federico Gomez Children's Hospital of Mexico (2002-2003),with positive culture for Sp bacteriologically confirmed in middle ear fluid obtained by tympanocentesis. All Sp were serotyped. A total of 138 samples from 135 children with AOM were included. RESULTS: Sp was isolated in 72 samples from 70 children. Sixty (85.7%) were previously healthy and 10 (14.3%) were immunocompromised. The most common serotypes were 6B and 19F (16.67%), and 6 A, 14 and 23F (15.27%). CONCLUSION: The distribution of serotypes among the children with AOM in the study is similar to that reported in developing cities, and 63.9% of the isolated serotypes are found to be included in the 7-Valent Pneumococcal Conjugate Vaccine (PCV), 68.1% in the 10-Valent PCV and 83.3% in 13-Valent PCV.

Genital primary herpes simplex infection in a 5-month-old infant.

Genital primary herpes simplex infection is very uncommon in infants. Asymptomatic and oral primary infections are the most frequent presentations in this age group. We report a case of genital primary herpetic infection in a 5-month-old male, exclusively breastfed, whose mother suffered from active labial herpes.

New Intravenous Calcimimetic Agents: New Options, New Problems. An Example on How Clinical, Economical and Ethical Considerations Affect Choice of Treatment.

BACKGROUND: Dialysis treatment is improving, but several long-term problems remain unsolved, including metabolic bone disease linked to chronic kidney disease (CKD-MBD). The availability of new, efficacious but expensive drugs (intravenous calcimimetic agents) poses ethical problems, especially in the setting of budget limitations. METHODS: Reasons of choice, side effects, biochemical trends were discussed in a cohort of 15 patients (13% of the dialysis population) who stared treatment with intravenous calcimimetics in a single center. All patients had previously been treated with oral calcimimetic agents; dialysis efficacy was at target in 14/15; hemodiafiltration was employed in 10/15. Median Charlson Comorbidity Index was 8. The indications were discussed according to the principlist ethics (beneficience, non maleficience, justice and autonomy). Biochemical results were analyzed to support the clinical-ethical choices. RESULTS: In the context of a strict clinical and biochemical surveillance, the lack of side effects ensured "non-maleficence"; efficacy was at least similar to oral calcimimetic agents, but tolerance was better. Autonomy was respected through a shared decision-making model; all patients appreciated the reduction of the drug burden, and most acknowledged better control of their biochemical data. The ethical conflict resides in the balance between the clinical "beneficience, non-maleficience" advantage and "justice" (economic impact of treatment, potentially in attrition with other resources, since the drug is expensive and included in the dialysis bundle). The dilemma is more relevant when a patient's life expectancy is short (economic impact without clear clinical advantages), or when non-compliance is an issue (unclear advantage if the whole treatment is not correctly taken). CONCLUSIONS: In a context of person-centered medicine, autonomy, beneficence and non-maleficence should weight more than economic justice. While ethical discussions are not aimed at finding "the right answer" but asking "the right questions", this example can raise awareness of the importance of including an ethical analysis in the choice of "economically relevant" drugs.

Lymphangioma-like Kaposi sarcoma: case report.

Kaposi sarcoma (KS) is a multifocal vascular disease with uncertain histogenesis. It is characterized by clinical and histologic polymorphism. The "lymphangioma-like" variant is very uncommon, accounting for less than 5% of all cases. We report the case of a 76-year-old woman, HIV negative, with a 4-year history of classic Kaposi sarcoma treated with cryotherapy who developed new bullous lesions on her lower extremities. Biopsy revealed histologic findings of lymphangioma-like KS (LLKS), together with areas of classic KS; HHV-8 staining was positive. Diagnosis of LLKS was made and the patient was proposed for radiotherapy. The lymphangioma-like Kaposi sarcoma is a rare morphologic expression of KS characterized by dilated and bizarrely shaped vascular channels lined by flattened endothelium permeating the dermis. "Bulla-like" lesions have been considered as a clinical hallmark of this variant. Its histologic appearance suggests a lymphatic origin of KS and it may resemble other vascular tumors. Findings of areas of typical KS and positive staining for HHV-8 may help to make a definitive diagnosis.

Chemically Assisted Dissection With Sodium 2-Mercaptoethanesulfonate (MESNA) in the Surgical Management of Pediatric Cholesteatoma.

OBJECTIVE: To evaluate the effectiveness of the chemically assisted dissection with sodium 2-mercaptoethanesulfonate (MESNA), in the reduction of residual and recurrent cholesteatoma after mastoidectomy in children with chronic cholesteatomatous otitis media (CCOM). STUDY DESIGN: Retrospective case-control study. SETTING: Tertiary referral center. POPULATION: One hundred forty mastoidectomies performed in patients under 18 years of age for the treatment of CCOM. INTERVENTIONS: Chemically assisted dissection (CAD) with MESNA compared with surgical dissection without MESNA. MAIN OUTCOME MEASURES: Recidivism of cholesteatoma (recurrence and residual disease), variations in the average of bone conduction threshold after treatment, and complications. RESULTS: Recidivism of cholesteatoma was significantly lower when CAD with MESNA was used (p < 0.0001). No difference was found in the mean variation of the average of bone conduction thresholds between the groups, confirming its safety profile regarding auditory function. Meatoplasty stenosis after surgery was more prevalent within CAD with MESNA group (p: 0.049). CONCLUSION: Recurrent and residual cholesteatoma remains a problem, especially in children and despite surgical techniques such as canal wall down mastoidectomy and endoscopic ear surgery. CAD with MESNA can be safe and effective to reduce recurrence rates. Multicenter and prospective studies with larger number of patients are needed to validate these findings. The higher rate of meatoplasty stenosis after CAD with MESNA merits additional clinical research to confirm these findings, as well as in vitro studies evaluating the effect of the drug on the activity of fibroblasts and other growth factors that may be involved.

Hamartoma of the Vallecula in a Five-Month-Old Infant- A Case Report.

INTRODUCTION: Hamartomas is a neoplasms composed of mature tissue elements from the affected site with disproportion between their components. Although lingual hamartomas are traditionally infrequent in the head and neck, a significant number of case reports with this disorder in infancy are arising from the literature. CASE REPORT: We present a remarkable case of a vallecular hamartoma in a 5-month-old infant. Moreover, the value of histopathological diagnosis was highlighted regarding the differentiation between hamartomas and other benign/reactive lesions. CONCLUSION: Surgical excision is regarded as the treatment of choice for vallecular hamartomas; in addition, no recurrence has been reported after complete resection.

Clinical and sociodemographic characteristics associated with disease severity in juvenile recurrent respiratory papillomatosis: A study of 104 patients in a tertiary care pediatric hospital.

BACKGROUND: Juvenile recurrent respiratory papillomatosis (JRRP) is generally aggressive and with a high recurrence rate. Currently, there is no definite curative treatment for JRRP. Therefore, a greater understanding of the aspects that influence the severity and prognosis of the disease is required. OBJECTIVE: The aim of this study was to establish the clinical and socioeconomic characteristics of pediatric patients with JRRP and its relationship with the severity of the disease in a tertiary care pediatric hospital. RESULTS: A strong relationship was observed between the severity of the disease and the age at the time of diagnosis, and having a tracheostomy. A moderate association was found between the severity of the disease and the age at the time of the study, the area of origin and the recurrence rate. None of the socioeconomic statuses had a correlation with the severity of the JRRP. CONCLUSIONS: JRRP is associated with multiple surgeries due to the recurrence and aggressiveness of the disease. The socioeconomic status does not seem to influence the severity of the disease, whereas younger patients and users of tracheostomy should receive a more strict follow-up given the increased risk of severe disease.
