RESUMEN

BACKGROUND: Acute otitis media (AOM) is the inflammation of the middle ear. It constitutes one of the most frequent infections which affects children and usually occurs between 6 to 24 months of age. AOM can emerge due to viruses and/or bacteria. The aim of the current systematic review is to assess in children between 6 months and 12 years of age with AOM, the efficacy of any antimicrobial agent or placebo compared with amoxicillinclavulanate, to measure the resolution of AOM or symptoms. METHODS: The medical databases PubMed (MEDLINE) and Web of Science were used. Data extraction and analysis were performed by two independent reviewers. Eligibility criteria were set, and only randomised control trials (RCTs) were included. Critical appraisal of the eligible studies was performed. Pooled analysis was conducted using the Review Manager v. 5.4.1 software (RevMan). RESULTS: Twelve RCTs were totally included. Three (25.0%) RCTs studied the impact of azithromycin, two (16.7%) investigated the impact of cefdinir, two (16.7%) investigated placebo, three (25.0%) studied quinolones, one (8.3%) investigated cefaclor and one (8.3%) studied penicillin V, compared to amoxicillin-clavulanate. In five (41.7%) RCTs, amoxicillin-clavulanate proved to be superior to azithromycin, cefdinir, placebo, cefaclor and penicillin V, while in seven (58.3%) RCTs its efficacy was comparable with other antimicrobials or placebo. The rates of AOM relapse after treatment with amoxicillin-clavulanate were comparable to those of other antimicrobials or placebo. However, amoxicillin-clavulanate was more effective in eradicating Streptococcus pneumoniae from the culture, when compared to cefdinir. The results of the meta-analysis were not evaluated due to substantial heterogeneity between studies. CONCLUSIONS: Amoxicillin-clavulanate should be the treatment of choice for children between 6 months and 12 years of age with AOM.

RESUMEN

Corona virus disease-2019 (COVID-19) emerged in Wuhan, China in December 2019 and was declared as a pandemic by the World Health Organization in March 2020. Although there is no complete treatment protocol for COVID-19, studies on this topic are ongoing, and it is known that broad-spectrum antibiotics such as cephalosporins are used for coinfections and symptoms in COVID-19 patients. Studies have shown that Staphylococcus aureus and Escherichia coli bacteria can cause symptoms such as diarrhea and coinfections accompanying COVID-19. Therefore, in this study, colon-targeted cefaclor monohydrate (CEF)-loaded poly(lactic-co-glycolic acid) (PLGA)-Eudragit S100 nanoparticles (NPs) were prepared using a nanoprecipitation technique. The particle sizes of the CEF-loaded NPs were between 171.4 and 198.8 nm. The encapsulation efficiency was in the range of 58.4%-81.2%. With dissolution studies, it has been concluded that formulations prepared with Eudragit S100 (E-coded) and Eudragit S100+PLGA (EP-coded) are pH-sensitive formulations and they are targetable to the colon, whereas the formulation prepared only with PLGA (P-coded) can release a higher CEF rate in the colon owing to the slow release properties of PLGA. The release kinetics were fitted to the Korsmeyer-Peppas and Weibull models. The antibacterial activity of E-, EP-, and P-coded formulations was 16-fold, 16-fold, and 2-fold higher than CEF, respectively, for S. aureus and E. coli according to the microdilution results. As a result of the time killing experiment, all formulations prepared were found to be more effective than the antibiotic itself for long periods. Consequently, all formulations prepared in this study hope to guide researchers/clinicians in treating both gram-positive and gram-negative bacteria-induced infections, as well as COVID-19 associated coinfections and symptoms.

RESUMEN

BACKGROUND: Wide-spectrum antibiotics have been favored to treat acute uncomplicated cystitis (AUC) for a long time, leading to the emergence of multi-drug resistant bacteria. We hypothesize that narrow-spectrum antibiotics might mitigate the issue and aim to investigate the clinical efficacy of cefaclor in patients with AUC. METHODS: We retrospectively reviewed the clinical data of female outpatients with AUC treated with cefaclor and evaluated the safety and clinical efficacy. Clinical cure was defined as the elimination of clinical symptom under 4 white blood cells (WBCs) per high power field on microscopy. RESULTS: Overall, 223 women with AUC were enrolled. Escherichia coli was the dominant pathogen (n = 160; 68.6%), followed by Klebsiella species and E. coli-extended spectrum ß-lactamase (ESBL) (n = 19; 8.1% and n = 18; 7.7%). Overall success rate was 94.0% (n = 219) and susceptibility rate of cefazolin was 84.1%, which was close to that of levofloxacin (82.9%). Ampicillin showed the lowest rate of 63.7% with a significantly greater resistance rate of 35.3% among all antibiotics (P < 0.001). In the subgroup analysis, the success rate in patients with resistance to levofloxacin or cefazolin was 100% (n = 24) or 93.3% (n = 14). The rate in patients with resistance to both antibiotics was 60.0% (n = 9), and the pathogens in the other 40.0% (n = 6) of patients with treatment failure were E. coli-ESBL. CONCLUSION: Cefaclor showed excellent efficacy in AUC patients, even in those with in vitro resistance to cefazolin or levofloxacin. Cefaclor may be considered as a first-line option in patients with AUC and a second-line option for those with levofloxacin treatment failure.

RESUMEN

Diabetic foot ulceration is a common and severe complication of diabetes, causing substantial social, medical, and economic burdens. Treatment of foot ulcers remains challenging, thus requiring increasing awareness and more efficient management. This study investigates the efficacy of ointments, containing as main active ingredient the olive oil extract of the marine isopod Ceratothoa oestroides, in the treatment of patients with diabetic foot ulcers. Fifty-two patients were allocated into four treatment groups either receiving therapy with an ointment containing extract of C. oestroides or extract of C. oestroides and eosin or extract of C. oestroides and cefaclor or no treatment. Patients were monitored for a period of 135 days by evaluation of transepidermal water loss, skin hydration, planimetry, photo-documentation, and clinical condition. Treatment with the extract of C. oestroides demonstrated significant healing properties that became evident after 45 days of treatment and resulted in complete ulcer healing in 61% of the patients. A significant improvement in transepidermal water loss (p < 0.001), skin hydration levels (p < 0.001), and wound area (p < 0.001) was observed in all patients. Similar efficacy was demonstrated for the combination of C. oestroides extract with eosin treatment (p < 0.001). On the contrary, the combination of C. oestroides extract with cefaclor antibiotic agent completely inhibited the healing properties of the isopod extract and did not improve water loss, skin hydration, or wound area. An important factor for C. oestroides extract healing properties is its selective activity against Gram negative bacteria. Ointments containing C. oestroides extract alone or combined with the antimicrobial agent eosin emerges as an effective regimen for the treatment of diabetic foot ulcers.

RESUMEN

RATIONALE: Hyper-IgE syndrome (HIES) is a rare primary immunodeficiency presenting as two forms including autosomal dominant HIES (AD-HIES) and autosomal recessive HIES (AR-HIES), which are mainly caused by mutations in STAT3 and DOCK8, respectively. To date, only about 500 cases have been reported worldwide including 37 cases in China. The spectrum and prevalence of mutations and molecular pathogenesis in HIES remain poorly understood. PATIENT CONCERNS: Here we reported two Chinese children presenting clinical manifestations of HIES. DIAGNOSIS: Based on medical history, clinical manifestations, and laboratory findings, a diagnosis of HIES was made for both children. Targeted next-generation sequencing (NGS) identified a novel heterozygous deletion of 15 bp (c.1960_1974del, p.G654_D658del or alternatively c.1966_1980del, and p.G656_D660del), and a recurrent missense mutation (c.1144C>T, p.R382W) in STAT3 in the two patients, respectively. INTERVENTIONS: The two patients have been given the successful treatment of skin infections with cefaclor. OUTCOMES: Both patients have been under follow-up for more than 6 months, with no signs of recurrent infections. LESSONS: Our results extend the spectrum of STAT3 mutations associated with ADHIES and highlight the value of targeted NGS in confirming diagnosis of genetic disorders.

RESUMEN

Bilateral correlated data are often encountered in medical researches such as ophthalmologic (or otolaryngologic) studies, in which each unit contributes information from paired organs to the data analysis, and the measurements from such paired organs are generally highly correlated. Various statistical methods have been developed to tackle intra-class correlation on bilateral correlated data analysis. In practice, it is very important to adjust the effect of confounder on statistical inferences, since either ignoring the intra-class correlation or confounding effect may lead to biased results. In this article, we propose three approaches for testing common risk difference for stratified bilateral correlated data under the assumption of equal correlation. Five confidence intervals of common difference of two proportions are derived. The performance of the proposed test methods and confidence interval estimations is evaluated by Monte Carlo simulations. The simulation results show that the score test statistic outperforms other statistics in the sense that the former has robust type I error rates with high powers. The score confidence interval induced from the score test statistic performs satisfactorily in terms of coverage probabilities with reasonable interval widths. A real data set from an otolaryngologic study is used to illustrate the proposed methodologies.

RESUMEN

OBJECTIVES: To investigate teeth's antibiotic-induced color differences after bleaching using two different techniques. MATERIALS AND METHODS: One hundred twenty extracted maxillar human incisors were examined. The specimens were randomly divided into six groups, each receiving one of six antibiotic paste fillings: (1) triple antibiotic paste (TAP) with minocycline, (2) double antibiotic paste (DAP), (3) TAP with amoxicillin, (4) TAP with cefaclor, (5) TAP with doxycycline, and (6) no filling (control group). Spectrophotometric measurements were obtained at baseline and then during the first, second, and third weeks after paste placement. The specimens discolored by antibiotics pastes were randomly divided into two subgroups: (1) internal bleaching with hydrogen peroxide (H2O2) and (2) internal bleaching with H2O2 plus Nd-YAG laser irradiation. The ∆E value was calculated and analyzed using a two-way analysis of variance and post-hoc Tukey's test (α = 0.05). RESULTS: The ∆E for all groups showed color differences exceeding the perceptibility threshold (∆E Ëƒ 3.7) at all time points except in the control and DAP groups. Minocycline-induced TAP showed the most severe coronal discoloration (32.42). When the ∆E was examined, thermo/photo bleaching (22.01 ± 8.23) caused more bleaching than walking bleaching (19.73 ± 5.73) at every time point (P = 0.19). No group returned to the original color after bleaching (P < 0.05). CONCLUSIONS: Except for DAP, all antibiotic pastes caused discoloration. Internal bleaching with Nd-YAG laser can be useful for bleaching/removing this discoloration. CLINICAL RELEVANCE: For clinically successful final appearances, understanding the effects of bleaching procedures on antibiotic paste discoloration is important.

RESUMEN

BACKGROUND: The clinical and financial burden from bladder infections is significant. Daily antibiotic use is the recommended strategy for recurrent urinary tract infection prevention. Increasing antibiotic resistance rates, however, require immediate identification of innovative alternative prophylactic therapies. This systematic review aims to provide guidance on gaps in evidence to guide future research. OBJECTIVE: The objective of this review was to provide current pooled estimates of randomized control trials comparing the effects of nitrofurantoin vs other agents in reducing recurrent urinary tract infections in adult, nonpregnant women and assess relative adverse side effects. DATA SOURCES: Data sources included the following: MEDLINE, Jan. 1, 1946, to Jan. 31, 2015; Cochrane Central Register of Controlled Trials the Cochrane Database of Systematic Reviews, and web sites of the National Institute for Clinical Excellence, and the National Guideline Clearinghouse from 2000 to 2015. Randomized control trials of women with recurrent urinary tract infections comparing nitrofurantoin with any other treatment were included. STUDY DESIGN: A protocol for the study was developed a priori. Published guidance was followed for assessment of study quality. All meta-analyses were performed using random-effects models with Stats Direct Software. Dual review was used for all decisions and data abstraction. RESULTS: Twelve randomized control trials involving 1063 patients were included. One study that had a serious flaw was rated poor in quality, one study rated good, and the remainder fair. No significant differences in prophylactic antibiotic treatment with nitrofurantoin and norfloxacin, trimethoprim, sulfamethoxazole/trimethoprim, methamine hippurate, estriol, or cefaclor were found in clinical or microbiological cure in adult nonpregnant women with recurrent urinary tract infections (9 randomized control trials, 673 patients, relative risk ratio, 1.06; 95% confidence interval, 0.89-1.27; I2, 65%; and 12 randomized control trials, 1063 patients, relative risk ratio, 1.06; 95% confidence interval, 0.90-1.26; I2, 76%, respectively). Duration of prophylaxis also did not have a significant impact on outcomes. There was a statistically significant difference in overall adverse effects, with nitrofurantoin resulting in greater risk than other prophylactic treatments (10 randomized control trials, 948 patients, relative risk ratio, 2.17; 95% confidence interval, 1.34-3.50; I2, 61%). Overall, the majority of nitrofurantoin adverse effects were gastrointestinal, with a significant difference for withdrawals (12 randomized control trials, 1063 patients, relative risk ratio, 2.14; 95% confidence interval, 1.28-3.56; I2, 8%). CONCLUSION: Nitrofurantoin had similar efficacy but a greater risk of adverse events than other prophylactic treatments. Balancing the risks of adverse events, particularly gastrointestinal symptoms, with potential benefits of decreasing collateral ecological damage should be considered if selecting nitrofurantoin.

RESUMEN

INTRODUCTION: Antibiotic pastes are used for disinfection in regenerative endodontic procedures. This study evaluated the crown discoloration induced by various antibiotic pastes including the mixture of metronidazole and ciprofloxacin with minocycline, doxycycline, amoxicillin, or cefaclor. METHODS: Seventy extracted bovine incisors were sectioned to obtain a standardized root length of 10 mm above the facial cementoenamel junction. After pulp tissue removal, irrigation with sodium hypochlorite and the placement of temporary filling material and cotton pellet were performed from the apical aspect. The specimens were then randomly divided into 7 groups (n = 10 for each group), and each group received the following antibiotic paste fillings: no filling (control group), calcium hydroxide, double antibiotic paste (DAP), triple antibiotic paste (TAP) with minocycline, TAP with doxycycline, TAP with amoxicillin, and TAP with cefaclor. Spectrophotometric readings were obtained on the buccal surfaces of the crown on day 1 to week 3 after filling, and the ΔE value was calculated. Data were analyzed with 2-way analysis of variance and the Tukey post hoc tests (P = .05), and the human perceptibility threshold was set to 3.7. RESULTS: TAP with minocycline, doxycycline, and cefaclor induced more coronal discoloration compared with the control group (P < .05). The control, calcium hydroxide, and DAP groups showed no color changes exceeding the perceptibility threshold at all time points. CONCLUSIONS: The results indicated that all antibiotic pastes, except DAP, induced crown discoloration.

RESUMEN

The purpose of this case series was to report on the use of a technique of revascularization for necrotic immature permanent teeth, several problems encountered, and solutions to those problems. Eighteen pulp revascularizations were performed in 2009 using the original protocol of revascularization (adapted from the AAE/AAPD joint meeting in 2007 in Chicago). The protocol consisted of opening the canal and disinfecting it with sodium hypochlorite, sealing in a triple antibiotic paste for 2-6 weeks, re-opening, re-irrigating, creating a blood clot in the canal, and sealing with an MTA barrier over the clot. Three problems were encountered during the treatment: (1) bluish discoloration of the crown; (2) failure to produce bleeding; and (3) collapse of the mineral trioxide aggregate (MTA) material into the canal. Modifications to solve these problems included: changing one of the antibiotics, using a local anesthesia without epinephrine, and adding collagen matrix to the blood clot.

RESUMEN

AIM: The duration of therapy represents a fundamental aspect in the compliance to the therapy of child pathologies, such as pharyngotonsillitis, treated with oral therapy. Although penicillin and amoxicillin are the first choice antibiotics in the case of a child suffering from pharyngotonsillitis with the proven presence of Group A ß-hemolytic Streptococcus (GAS), the number of orally administered doses and 10 days of therapy, considerably lower the compliance. METHODS: An open phase IV randomized multicenter clinical trial was conducted in parallel groups, involving 49 family pediatrician (FP), distributed over the entire national territory, enrolling 435 children suffering from GAS-FT. 210 children received Cefaclor, 50 mg/kg/day, administered twice daily for five days, whilst 213 children received amoxicillin/clavulanate 40 mg/kg/day administered twice daily for 10 days. RESULTS: The results showed percentages of eradication of 88.4% for the Cefaclor group and 94.3% for the amoxicillin/clavulanate group, and a positive clinical judgement of 92.3% for the Cefaclor group and 96.6% for the amoxicillin/clavulanate group. The two arms of the study did not have any significant statistical differences, neither for the eradication, nor for the clinical judgement nor for the reduction of the Milano Score between the beginning and the end of treatment, with a P=0.042 for amoxicillin/clavulanate for eradication. CONCLUSION: This study confirms that the administration of Cefaclor for five days during GAS-FT has the same efficacy as a 10-day therapy with amoxicillin/clavulanate, with a clearly different compliance.

RESUMEN

This study assessed the prevalence and microbial interactions of Fusobacterium nucleatum and Fusobacterium necrophorum in primary endodontic infections from a Brazilian population and their antimicrobial susceptibility to some antibiotics by the E-test. One hundred ten samples from infected teeth with periapical pathologies were analyzed by culture methods. Five hundred eighty individual strains were isolated; 81.4% were strict anaerobes. F. nucleatum was found in 38 root canals and was associated with Porphyromonas gingivalis, Prevotella spp., and Eubacterium spp. F. necrophorum was found in 20 root canals and was associated with Peptostreptococcus prevotii. The simultaneous presence of F. nucleatum and F. necrophorum was not related to endodontic symptoms (p > 0.05). They were 100% susceptible to amoxicillin, amoxicillin/clavulanate, and cephaclor. Fusobacterium spp. is frequently isolated from primary-infected root canals of teeth with periapical pathologies. Amoxicillin is a useful antibiotic against F. nucleatum and F. necrophorum in endodontic infections and has been prescribed as the first choice in Brazil.

RESUMEN

The purpose of this report was to present the case of a patient wherein revascularization of the necrotic infected pulp space of an immature permanent maxillary central incisor tooth was induced in vivo by stimulation of a blood clot from the periapical tissues into the canal space. This was achieved after disinfection of the canal space with a topical antibiotic paste followed by a blood clot scaffold induced from the periapical tissues. This treatment approach offers clinicians great potential to avoid the need for traditional apexification with calcium hydroxide or the need to achieve an artificial apical barrier with mineral trioxide aggregate. Furthermore, this treatment approach can help rescue infected immature teeth by physiologically strengthening the root walls.

RESUMEN

OBJECTIVES: To describe the different modalities of ambulatory management of acute pyelonephritis in patients older than 3 months of age in paediatric emergency units of the Ile de France region in 2004. METHODS: Between October 2003 and April 2004, referents of 39 paediatric emergency units of the Ile de France region were questioned through a written questionnaire concerning the management of acute pyelonephritis: in or outpatient modalities, antibiotic regimen (molecule and route of administration), investigations and follow-up. RESULTS: Thirty-one questionnaires (79.5%) were returned and analysed. A written protocol was available in 60% of the units. Outpatient management was performed in 24/31 centres. Young age, poor clinical tolerance, urological abnormalities and social difficulties were the major contra-indications for such management. Ultrasonic echography at diagnosis (within 24 h) was performed in 50% of the units. Antibiotics were started using IV route in 18/24 units (75%) and ceftriaxone and aminoside were respectively prescribed in 100% and 29.4% of the units for a duration of 1 to 5 days before switching to the oral route. Antibiotherapy was started orally in 6 units and cefixime was chosen by 5 of them. Follow-up consultations were scheduled in 100% of the units but with various delay after initiation of the treatment. The total duration of treatment was mostly 10 days and oral prophylactic antibiotherapy was prescribed by 10/24 centres after completion of the treatment. Cystoureterography was systematically realized by 83.3% of the units. CONCLUSIONS: Despite important differences in the management of acute pyelonephritis in Ile-de-France, a majority of the units follows similar therapeutic modalities. In the absence of consensus, new recommendations are necessary concerning the management of pyelonephritis in infants and children in France.

RESUMEN

Acute Otitis Media (AOM) is the most frequent respiratory tract infection of infancy and childhood that is treated with antimicrobial agents. The most common causative pathogens include Streptococcus pneumoniae, Hemophilus influenzae and Moxarella catarrhalis, and therefore antibacterial management should target against these isolates. Cefaclor, a congener of cephalexin monohydrate, is a semisynthetic cephalosporin antibiotic. It is an orally active cephalosporin which has demonstrated activity against a wide range of organisms in vitro. Present study is designed as a multicentric prospective trial to study and compare the efficacy and safety of cefaclor versus amoxicillin + clav in children with acute otitis media. One hundred and sixty seven patients were evaluated for efficacy endpoints in the cefaclor arm comprised of 104 males and 63 females with a mean age of 5.74+/-2.80 years and 185 patients in the amoxy-clav group comprised of 118 males and 67 females with a mean age of 4.93+/-2.92 years. Both cefaclor and amoxy-clav caused a significant improvement in all the signs and symptoms after a 10-day treatment period. However, between-the-group comparisons showed that the reduction in most of the symptoms was significantly more in cefaclor arm as compared to amoxicillin-clav arm. The clinical success (clinical cure + improvement) at the end of therapy was significantly more in cefaclor arm: 98% with cefaclor versus 85% with amoxicillin + clav, p<0.05 Table 3. Failure cases were prescribed other antibiotics according to the culture sensitivity reports, as rescue medication. Bacterial eradication rates were largely consistent with clinical responses. Bacteriological eradication was seen in 95% of patients in cefaclor group and 78% of patients in amoxicillin + clav group. In conclusion, cefaclor is a well tolerated and effective antibacterial option for acute otitis media in children and it is superior to the combination of amoxicillin + clav in efficacy and tolerability in acute AOM. Moreover, its expanded spectrum of activity, ability to achieve adequate concentrations in tissues, suitability for twice-daily dosing, and proven tolerability suggest that it is a good alternative to agents traditionally used in acute otitis media.

RESUMEN

OBJECTIVE: To observe the clinical efficacy of Qingqiao Capsule (QQC) in treating patients with secretory otitis media (SOM). METHODS: A total of 90 patients were randomly assigned into the treated group (n = 45) and the control group (n = 45). Patients in the treated group were administrated with QQC, 5 capsules each time, 3 times a day for totally 10-14 days, and those in the control group were given per os cefaclor capsules 0.5 g each time for adult, 3 times a day, or 20 mg/(kg.d) for children, for 10-14 days. The therapeutic efficacy of treatment on the patients was observed and compared after treatment and followed up for 3-6 months. RESULTS: (1) The clinical efficacy in the treated group was superior to that in the control group with significant statistical difference (P < 0.01); (2) Comparison of the efficacies in patients of three different TCM syndrome types (the external pathogenic wind invasion caused auditory orifice stuffiness type, the Gan-Dan damp-heat steaming up auditory orifice type and the Pi-deficiency dysfunction induced dirty dampness blocking ear type) showed no statistically significant difference (P > 0.05); (3) The vanishing rate and time needed of the main symptoms and signs in the treated group were superior to those in the control group on ear muffle, tinnitus, hearing impairment, hydrotypanum, pure tone threshold and abnormal tongue figure, and the difference was statistically significant (P < 0.05 or P < 0.01), only those of earache, otopiesis and abnormal pulse figure were insignificantly different between the two groups (P > 0.05). CONCLUSION: QQC is an effective Chinese composite medicine on patients with SOM, and shows no obvious adverse reaction.

RESUMEN

UNLABELLED: Sexual intercourse has been established as one of the most important risk factors for both isolated and recurrent uncomplicated infections of the urinary tract. Prophylactic therapy requires only a small dose of an antimicrobial agent, which is generally given at bedtime for 6 to 12 months. An alternative method is to give an antimicrobial agent for six months post-intercourse. It is still unknown which of the two methods is most effective. A total of 123 women with suspected sexually induced recurrent cystitis (mean age 28 years, range 15 to 65) and a history of recurrent urinary tract infection (UTI) (the last one within the last six months) were subjected to prophylactic therapy for six months. Half of them were treated with low-dose trimethoprim-cotrimoxazole (TMP-SMX) and cefaclor given orally post-intercourse (spontaneous usage), while the other half were treated with low-dose TMP-SMX and cefaclor given at bedtime. The response to the prophylactic therapy was classified as continued cure in 106 cases (86.17%), failure in 13 cases (10.56%), and unknown in four cases (3.25%). TMP-SMX administered in continuous nightly prophylaxis showed similar efficacy and tolerability as cefaclor post-intercourse. OBJECTIVE: To determine the efficacy of prophylaxis in women with recurrent sex induced cystitis and compare the post-intercourse versus the conventional bedtime given long-term, low-dose use of prophylactic antimicrobials.
