RESUMO

Vulvovaginal candidiasis is a public health problem with a high incidence among female patients. Currently, there is an increase in the identification of Candida spp. resistant to current therapy, making it necessary to search for new therapeutic alternatives. The synergistic potential of curcumin with fluconazole is described in the literature. However, due to its high lipophilicity, it is necessary to use drug-delivery systems to adequately explore its potential, among which is the nanostructured lipid carrier. However, to date, there is no validated method of high-performance liquid chromatography for simultaneous determination of fluconazole and curcumin in the literature. Thus, the present work developed a high-performance liquid chromatography method for simultaneous determination of fluconazole and curcumin co-encapsulated in nanostructured lipid carrier which was validated according to the International Conference on Harmonization (Technical Requirements for Registration of Pharmaceuticals for Human Use) - Q2 (R1) and the Food and Drug Administration - Guidance for Bioanalytical Method. The method was applied to determine the encapsulation efficiency and drug-loading of curcumin and fluconazole in nanostructured lipid carriers. The developed method proved to be selective, precise, accurate, and robust for the simultaneous determination of both drugs, enabling the quantification of encapsulation efficiency and drug-loading of curcumin and fluconazole in nanostructured lipid carriers.

RESUMO

BACKGROUND: Cough is a common symptom in several respiratory diseases and may occur in healthy subjects as a defense mechanism against noxious inhalants. Cough response is mediated by transient receptor potential vanilloid-1 (TRPV1) expressed by C-fibers in the airways. Capsaicin (CPS) activates TRPV1 and is regularly used as a tool to study cough response. Although single nucleotide polymorphisms (SNPs) of TRPV1 are implicated in CPS binding, their role in cough response is not fully elucidated. AIMS: In this study we investigated the relationship between capsaicin cough challenge sensitivity and multiple TRPV1 polymorphisms. METHODS: The dose-response of cough induced by CPS inhalation was determined in 20 unselected healthy volunteers and the concentration of CPS causing two coughs (C2) was calculated. The SNPs I585V(rs8065080), T505A(rs17633288), T469I(rs224534), I315 M(rs222747), P91S(rs222749), and K2N(rs9894618) were characterized in blood DNA from each subject. The association between combinations of TRPV1 SNPs and CPS sensitivity of each subject was assessed by linear regression. RESULTS: All subjects were wild type for T505A and K2N, while they exhibited two to six SNPs with high capsaicin responsiveness. The major contribution to CPS sensitivity in vivo (C2) was due to four combined SNPs: 315 M, 585I, 469I and 91S (p = 0.015). We found, however, that the presence of a minimum of two polymorphisms, such as 91S combined with 315 M (p = 0.032) or 91S with 585I (p = 0.025), was sufficient to detect an effect on C2. CONCLUSION: Capsaicin cough challenge sensitivity in healthy subjects is dependent on multiple TRPV1 polymorphisms.

RESUMO

Owing to the growing resistance among isolates of Candida species to usual antifungal agents and the well-known therapeutic potential of curcumin, the purpose of this study was to develop and validate a vaginal formulation containing this substance and to evaluating its effectiveness in the treatment of experimental vulvovaginal candidiasis. Curcumin was incorporated in a vaginal cream in three concentrations (0.01%, 0.1% and 1.0%). The different concentrations of the cream and its controls were intravaginally administered in an immunosuppressed rat model to evaluate the efficacy in the treatment of experimental vulvovaginal candidiasis. Samples of the cream were also subjected to centrifugation and physical stability tests and an analytical method for quantification of curcumin was validated based on HPLC. The formulation was stable and the HPLC method could be considered suitable for the quantitative determination of curcumin in the cream. After 6 days of preclinical study, the number of infected animals was 1/6 in all groups treated with curcumin vaginal cream and the fungal burden showed a progressive reduction. Reduction in the inflammatory infiltrate was observed in the group treated with 1.0% cream. Vaginal cream containing curcumin could be considered a promising effective antifungal medicine in the treatment of vulvovaginal candidiasis.

RESUMO

Microemulsions (MEs) loaded with methyl dihydrojasmonate (MJ) were developed to improve the aqueous solubility of this drug. The composition of the formulations ranged according to the oil/surfactant ratio (O/S). The MEs were characterized according to diameter of droplets, X-ray diffraction and polarized light microscopy. The MJ identification and quantification was performed by gas chromatography-mass spectrometry (GC-MS). The MJ showed a retention time of ∼16.7 min for all samples. The obtained correlation coefficient from the calibration graph was 0.991. The developed analytical method was effective enough to quantify low and high concentrations of MJ. The increase of the O/S ME ratio led to a reduction of the droplet diameter. All formulations showed an amorphous structure and the behavior varied between isotropic and anisotropic systems. A decrease in the release of MJ with the increase of the O/S ratio in the formulations was observed. The analytical method developed for the quantitative determination of MJ is suitable to detect and quantify the drug compound from different compositions of MEs in the in vitro release test, and by analogy in other prolonged effects related to the drug reservoir effect of these systems was observed, revealing that ME can be a promising nanocarrier for MJ delivery to tumor cells.

RESUMO

Methotrexate (MTX) is an immunosuppressive drug for systemic use in the treatment of skin diseases, however, MTX presents a number of side effects, such as hepatotoxicity. To overcome this limitation, this study developed skin MTX delivery surfactant systems, such as a microemulsion (ME) and a liquid crystalline system (LCS), consisting of a glycol copolymer-based silicone fluid (SFGC) as oil phase, polyether functional siloxane (PFS) as surfactant, and carbomer homopolymer type A (C971) dispersion at 0.5% (wt/wt) as aqueous phase. Polarized light microscopy and small-angle X-ray scattering evidenced the presence of hexagonal and lamellar LCSs, and also a ME. Texture profile and in vitro bioadhesion assays showed that these formulations are suitable for topical application, showing interesting hardness, adhesiveness and compressibility values. Rheology analysis confirmed the Newtonian behaviour of the ME, whereas lamellar and hexagonal LCSs behave as pseudoplastic and dilatant non-Newtonian fluids, respectively. In vitro release profiles indicated that MTX could be released in a controlled manner from all the systems, and the Weibull model showed the highest adjusted coefficient of determination. Finally, the formulations were not cytotoxic to the immortalized human keratinocyte line HaCaT. Therefore, these bioadhesive surfactant systems established with PFS and C971 have great potential as skin delivery systems.

RESUMO

BACKGROUND: Increased infertility and smaller volume accompany undescended testis. Timing of orchiopexy is still a matter of debate. We evaluated the growth of non-palpable testes after laparoscopic orchiopexy according to age at surgery, intraoperative findings and type of procedure. METHODS: Forty-one boys undergoing laparoscopy for nonpalpable testes were retrospectively reviewed and divided into two groups, ≤18 months and >18 months, according to their age at surgery. RESULTS: At follow-up, 14 testes in the younger group had normal size, while 3 atrophied either after single (2) or two stage procedure (1). Similarly, in older boys 11 testes grew normally, while 5 atrophied after both procedures. CONCLUSIONS: Most of the non-palpable testes grew normally after laparoscopic orchiopexy and the postoperative volume seemed independent from the surgical strategy. Both techniques led to a few cases of testicular hypotrophy. In our experience, the age at surgery did not affect the outcome in terms of testicular growth.

RESUMO

OBJECTIVES: Lung diffusing capacity for carbon monoxide (DLCO) is impaired in interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) associated to systemic sclerosis (SSc), but the mechanism of DLCO reduction remains controversial. We hypothesised that the determinants of DLCO impairment differ in interstitial or vascular involvement of the lung of SSc patients. METHODS: DLCO was partitioned into alveolar-capillary membrane conductance (Dm) and pulmonary capillary blood volume (Vc) using combined single-breath DLNO and DLCO measurements. Seventeen SSc patients without pulmonary involvement (SSc), 20 SSc patients with ILD (SSc-ILD), with and without PAH, and 21 healthy controls were included. RESULTS: DLNO and Dm were reduced in SSc patients as compared with controls, whereas Vc was not significantly different. SSc-ILD patients showed a highly significant decrease in Dm and Vc as compared with SSc patients and controls. Vc tended to be more reduced than Dm in SSc-ILD patients with PAH. Dm and Vc were negatively correlated with PAPs and HCRT scores, but the relationship with the HRCT score was stronger. CONCLUSIONS: DLNO is more sensitive than DLCO in detecting functional impairment in SSc without radiologic or haemodynamic alterations. A disproportional reduction of Dm relative to Vc suggests a thickening of the blood-gas diffusion barrier in these patients. In SSc patients with detectable ILD, the gas exchange impairment is due to both components of lung diffusing capacity, and partitioning of DLCO in Dm and Vc is of little use in distinguishing the patients with only ILD from those with ILD complicated by PAH.

RESUMO

The purpose of this study was to evaluate the in vitro anticandidal activity of a methanolic extract of Syngonanthus nitens scapes against different Candida species and clinical isolates from patients with vulvovaginal candidiasis (VVC), and its effect in vivo in the treatment of vaginal infection. Chemical characterization of the extract was performed by HPLC-UV analyses and showed the presence of flavones derivatives. The extract was effective against several Candida strains from our collection and species recovered from VVC patients, and was able to inhibit the yeast-hyphal transition. No cytotoxic activity against human female reproductive tract epithelial cells and no hemolytic activity against human red blood cells were observed. In the in vivo model of VVC, we evaluated the efficacy of the intravaginal treatment with a cream containing the extract at doses of 0.5, 1.0 and 2.0%. The treatment eradicated the vaginal fungal burden in infected rats after 8 days of treatment. S. nitens extract could be considered as an effective and non-toxic natural antifungal agent in the treatment of vulvovaginal candidiasis.

RESUMO

BACKGROUND: Increased expression of ceramide has been detected in emphysema. Ceramide promotes autophagy and apoptosis, which concur with cellular homeostasis. OBJECTIVES: To determine whether ceramide expression is associated with the development of chronic obstructive pulmonary disease (COPD) and with altered cellular homeostasis in lung parenchyma. METHODS: We studied 10 subjects with severe COPD, 13 with mild/moderate COPD, 11 with idiopathic pulmonary fibrosis (IPF), 12 non-COPD smokers, and 11 nonsmoking controls. The immunoreactivity for ceramide along with markers of autophagy (LC3B), apoptosis (cleaved caspase-3), and cell proliferation (MIB1) was quantified in alveolar walls. RESULTS: Ceramide expression was increased in COPD patients compared with control smokers and was related to the impairment of gas exchange but not to the degree of airflow limitation. In COPD, an important activation of apoptosis and autophagy pathways was observed, particularly in patients with severe disease, that was not counterbalanced by cell proliferation. Upregulation of ceramide was observed even in subjects with IPF in whom activation of apoptosis and autophagy was negligible and cell proliferation was instead the most prominent feature. CONCLUSIONS: Ceramide expression, which is increased in COPD and even more so in IPF, appears to be neither specific nor related to COPD severity, probably representing a broader marker of lung damage. In contrast, apoptosis and autophagy are characteristics of the COPD pathology, particularly in its most severe stage.

RESUMO

Background: The aim of this study was to evaluate the quality of our surgical informed consent and parents'/guardians' late recall of surgical procedures and risks of elective day surgery after pre-operative interview with surgeons. Methods: All parents/guardians of patients <18 years of age undergoing minor and intermediate elective procedures from January 15th to September 1st, 2022, were prospectively enrolled in the study. Before discharge, parents/guardians were asked to complete an in-house questionnaire regarding the duration of the consent procedure, duration of the interview, quality of the informative handouts, and their ability to recall the type of disease, type of surgical procedure, and surgical risks. Results: One hundred and two questionnaires were returned. In all cases, informed consent was obtained between 24 and 72 h prior to surgery. The following responses were collected: 98/102 (96%) parents/guardians reported that the duration of the consent process was adequate; 95/102 (93%) reported that the handouts were fully informative, and 7/102 (7%) reported that they were partially informative regarding explanation of the disease and surgical procedure; regarding complications, 93/102 (91%) perceived the handouts to be fully/partially informative, while 4/102 (4%) perceived the handouts to be poorly/non-informative, and 5/102 (5%) did not provide a response; 94/102 (92%) stated that they remembered the pathology, but only 87/94 (93%) recalled it correctly; 90/102 (88%) stated that they remembered the type of procedure, but only 76/90 (84%) recalled it correctly; and 53/102 (52%) stated that they remembered the surgical risks, but only 20/53 (38%) could recall more than one complication. Conclusions: Late recall of surgical complications by parents was poor despite the high perceived quality of the surgical risk handouts and medical interview. Implementation of expedient methods may improve overall comprehension and satisfaction of parents/guardians regarding the IC process. Further, more efforts should be made to develop standardized guidelines for an optimal IC process.

RESUMO

Background and Objective: The use of robotic-assisted surgery (RAS) has increased more slowly in pediatrics than in the adult population. Despite the many advantages of robotic instruments, the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) still presents some limitations for use in pediatric surgery. This study aims to examine evidence-based indications for RAS in the different fields of pediatric surgery according to the published literature. Methods: A database search (MEDLINE, Scopus, Web of Science) was performed to identify articles covering any aspect of RAS in the pediatric population. Using Boolean operators AND/OR, all possible combinations of the following search terms were used: robotic surgery, pediatrics, neonatal surgery, thoracic surgery, abdominal surgery, urologic surgery, hepatobiliary surgery, and surgical oncology. The selection criteria were limited to the English language, pediatric patients (under 18 years of age), and articles published after 2010. Key Content and Findings: A total of 239 abstracts were reviewed. Of these, 10 published articles met the purposes of our study with the highest level of evidence and therefore were analyzed. Notably, most of the articles included in this review reported evidence-based indications in urological surgery. Conclusions: According to this study, the exclusive indications for RAS in the pediatric population are pyeloplasty for ureteropelvic junction obstruction in older children and ureteral reimplantation according to the Lich-Gregoire technique in selected cases for the need to access the pelvis with a narrow anatomical and working space. All other indications for RAS in pediatric surgery are still under discussion to date, and cannot be supported by papers with a high level of evidence. However, RAS is certainly a promising technology. Further evidence is strongly encouraged in the future.

RESUMO

BACKGROUND: Pleural effusion and empyema are frequent complications of acute bacterial pneumonia in children. To date, evidence regarding the optimal treatment of this condition is limited in the literature. METHODS: Patients with pleural effusion and empyema admitted at our Department of Pediatric Surgery over the last ten years were enrolled in this retrospective study, and successively compared with the clinical charts of patients treated before the introduction of a new diagnostic and therapeutic algorithm. In particular, primary outcomes investigated between pre- and postalgorithm period were the use of diagnostic tools and antibiotics, the need for additional therapeutic approaches, complications, and the length of stay. RESULTS: After the introduction of the new algorithm there were a decrease in the use of chest radiography for re-evaluation (100% vs. 79%, P=0.003), a more focused use of computed tomography (68% vs. 15%, P=0.001), and a decrease in the use of a second computed tomography (18% vs. 3%, P=0.07); in favor of an increase in the use of the ultrasound scan (40% vs. 100%, P=0.001). There was also a shift from the use of chest tube drainage alone to the use of drainage for urokinase administration (50% vs. 92.3%, P=0.001), and a statistically significant decrease in the need for video-assisted thoracoscopic surgery (25% vs. 7.7%, P=0.001). CONCLUSIONS: The introduction of a diagnostic and therapeutic algorithm for the management of pediatric pleural effusion and empyema has notably resulted in a decrease in the utilization of radiography and computed tomography and an increase in the use of ultrasonography, reducing unnecessary radiation exposure in children and overall costs.

RESUMO

BACKGROUND: Older patients are at a higher risk of access site complications and bleeding. Systematic reviews and meta-analysis have highlighted the benefits of distal over proximal transradial access (mainly, lower rates of radial artery occlusion and faster hemostasis). We aimed to evaluate the feasibility and safety of distal transradial access (dTRA) for routine coronary procedures in older patients compared with non-older patients. METHODS: Retrospective analysis of a large and real-world sample of 5524 consecutive all-comers patients who underwent coronary procedures via dTRA were included in the DISTRACTION registry. RESULTS: In the older patients (greater than or equal to 65 years) group (n = 2594, 47%), there were higher rates of hypertension (83% vs 71.1%; P less than .0001), diabetes (45.1% vs 34.7%; P less than .0001), previous stroke (2.9% vs 2%; P=.0425), chronic heart failure (9.2% vs 7.1%; P=.0040), severe aortic valvar disease (4.2% vs 2.9%; P=.0070), chronic kidney disease stages 3 and 4 (8.1% vs 3.1%; P less than .0001), previous percutaneous coronary intervention (27.2% vs 24.5%; P=.0253), previous coronary artery bypass grafting (5.1% vs 2.2%; P less than .0001), cardiogenic shock at presentation (1.3% vs 0.4%; P=.0003), rotational atherectomy (0.7% vs 0.2%; P=.0050), and left main percutaneous coronary intervention (2.7% vs 1.5%; P=.0033). No significant differences were observed in the rates of access site crossovers. No major adverse cerebrovascular and cardiac events directly related to dTRA, no hand/thumb dysfunction or ischemia after any procedure, and no access site-related hematomas (early discharge after transradial stenting of coronary arteries greater than or equal to 2) were recorded. CONCLUSIONS: Despite more comorbidities, more complex coronary disease, and more challenging presentation, the adoption of dTRA as the default approach for routine coronary procedures in older patients, by proficient operators, appears to be safe and feasible.

RESUMO

Background: Esophageal atresia (EA) is a rare congenital malformation. A high incidence of GER unresponsive to medical management is noted with EA. Literature suggests that complications from GER can persist in adulthood. In paediatric age, laparoscopic treatment is a valid option even if recurrence rate is not negligible. Aims and Objectives: To evaluate our experience with gastro-esophageal reflux (GER) treatment after esophageal atresia (EA) repair. Materials and Methods: We retrospectively analysed 29 consecutive patients treated for EA at birth and studied for GER at our Institute in a period of 11 years. Results: 24/29 (82,7%) cases had symptoms of reflux, 17/29 (58,6%) cases were treated with laparoscopic fundoplication (LF). Three infants were younger than 6 months and had apparent life threatening events (ALTE) condition as principal indication for surgery. No intra-operative complications occurred. 3/17 LF had open surgical conversion due to technical problems. 2/17 cases required a second operation. At the last follow-up: (1) 6/17 (35,3%) of patients healed after the last operation, (2) 8/17 (47,1%) have GER improvement (four still in medical treatment), (3) 2/17 (11,8%) have persistent GER, (4) 1/17 (5,9%) died for causes not related to antireflux surgery. Conclusions: According to literature and to our retrospective analysis, LF for GER after EA repair is feasible, even if recurrence risk is not negligible. Infants less than 6 months old with associated conditions (malformations, gastrostomy/jejunostomy) seem to have a higher failure rate with a greater risk of conversion. Longer follow-up and multicenter experiences would guarantee an adequate surveillance for patients with EA.

RESUMO

Introduction: The management of primary spontaneous pneumothorax (PSP) in pediatrics remains controversial. The aim of this study was to investigate the risk of recurrence after non-surgical treatment vs. surgery, the difference in the length of stay (LOS) between various treatment options, and the role of computed tomography (CT) in the management of PSP. Materials and Methods: We retrospectively reviewed patients admitted to our Pediatric Surgery Unit for an episode of PSP between June 2009 and July 2020. Medical records including clinical presentation at admission, diagnostics, treatments, complications, and LOS were collected. Results: Twenty-three patients (22 males and 1 female) were included in this study. Median age was 15.65 (range 9-18). Chest X-rays were performed in all patients and showed 5 small (22%) and 18 large (78%) PSP. Chest drain was used for large PSP (≥2 cm) if the patient was clinically unstable. Eleven patients (48%) were managed non-operatively with observation alone and a recurrence rate of 18%, chest drain was used in 11 patients with a recurrence rate of 36%, and surgery was deemed necessary as a first treatment choice in one case. Six patients (27%) had an episode of relapse after non-operative management or chest drain placement. Following surgery, a relapse occurred in 2 of the 6 patients. Chest drain insertion was associated with a longer LOS than observation alone (6.36 vs. 2.4 days), and surgery resulted in a longer LOS than other types of treatment (P = 0.001). Conclusion: According to our experience, small PSP or clinically stable larger PSP can be treated conservatively with observation alone. Operative management should be taken into consideration in children with large symptomatic PSP, persistent air leak, and/or relapse after chest drain insertion.

RESUMO

Introduction: Pilonidal disease (PD) is a common infectious and inflammatory condition affecting the gluteal cleft and sacrococcygeal region. The optimal treatment for PD remains controversial. While the open technique reduces the number of relapses compared to minimally invasive approaches, it is associated with a longer healing time. Reactive oxygen species are a key part of the normal wound-healing process. Herein, we reported our preliminary experience using a new oxygen-enriched oil-based product called NovoX for wound healing after open surgery for PD. Materials and methods: We used a new oxygen-enriched product for wound healing in three pediatric patients undergoing open surgical repair for PD between December 2021 and April 2022. During postoperative follow-up, healing time and the aesthetic result were evaluated. Results: Our preliminary study included three patients with chronic PD. The average follow-up time was 5 weeks, corresponding to the end of the healing process and the resumption of normal daily activities. Only one mild complication occurred during the study period. No short-term side effects were reported. The cosmetic result was reported as satisfactory. Conclusion: NovoX is easy to apply, safe, and effective for treating pediatric patients undergoing open surgical treatment for PD, leading to slightly faster wound healing with good aesthetic outcomes.

The objective of this work was to evaluate the preservative effectiveness of liquid crystalline systems containing retynil palmitate (RP) by the challenge test (CT) and D-value. A system was developed containing water, silicon glycol copolymer, and polyether functional siloxane with 1% RP added. The analyses were carried out by methods in the U.S. Pharmacopeia (USP 31, 2008) using the microorganisms Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, and Aspergillus niger. The CT showed that after 7 days, all microorganisms were eliminated except A. niger, which maintained viability for at least 28 days after inoculation. Moreover, the microorganisms E. coli, P. aeruginosa, S. aureus, C. albicans, and A. niger presented different growth behaviors, evidenced by differences among the D-values calculated. It was concluded that the CT and D-value were efficient methods for evaluation of the preservative property of these formulations.

RESUMO

BACKGROUND: Sactosalpinx means a collection of fluid (serum, blood or pus) in the fallopian tube. CAH (Congenital Adrenal Hyperplasia) is a typical 46XX DSD (Disorder of Sex Development) due to a steroidogenic enzymatic defect. Both conditions are rare and can lead to reduced fertility rate. CASE PRESENTATION: We describe two post-menarche virgin girls with CAH who were hospitalized for acute abdomen due to laparoscopically confirmed sactosalpinx. Case 1 recovered after conservative management, case 2 after a second-look and bilateral salpingectomy. The first case consisted of right sactosalpinx and previous peritonitis reported; the second one of bilateral symptomatic pyosalpinx and previous vaginal stenosis. Recurrent abdominal pain persisted at follow-up in Case 1: post-operative MRI (Magnetic Resonance Imaging) showed bilateral hydrosapinx that disappeared at a following ultrasound scan control. Follow-up was uneventful 36 months after surgery in Case 2, except for the surgical revision of the vaginal introitus. CONCLUSIONS: CAH-sactosalpinx association is a very rare but not negligible event. We suggest a conservative approach for sactosalpinx if tubal and/or ovary torsion can be excluded. Pyosalpinx is more challenging to treat, but during pediatric age we suggest starting with a conservative approach, especially in patients with CAH who have a potential low fertility rate. Careful gynecological follow-up after menarche is recommended to rule out any further causes of infertility.
