Various surgical techniques are known for the treatment of flexible flatfoot in children after failure of nonsurgical attempts. Data collected in a review of the last 10-year period (2010-2020) show that among the 691 feet undergoing subtalar arthroereisis with endorthesis, average age at surgery was 11.40 years and in the 1856 feet that underwent subtalar arthroereisis with calcaneo-stop 11.69 years, while the complications rate was 9.00% and 6.38%, respectively. These data confirm that subtalar arthroereisis with calcaneo-stop may have an advantage over subtalar arthroereisis with endorthesis as the screw is not placed across the subtalar joint but instead into the calcaneus.Clubfoot overcorrection can develop gradually over years and is characterized in school age by hindfoot valgus position due to excessive rigid peritalar eversion, sometimes accompanied by supramalleolar valgus malalignment. Surgical treatment is recommended in severe cases and consists of bony realignment at the peritalar complex by osteotomy or fusion, correction of the supramalleolar valgus deformity in younger children by hemiepiphyseodesis, or osteotomy in adolescents. In addition, dorsal bunion requires stabilization of the medial tarsometatarsal ray and transfer of the tendons of Mm. tibialis anterior and flexor hallucis longus.The approach to treatment of severe untreated or recurrent congenital talipes equinovarus deformities is very different in the world where patients are mobile, have access to repeated return visits for follow-up treatment, and where more sophisticated options for gradual correction with external fixation are available. For treatment, talectomy may be the only option to treat certain neglected clubfoot deformities during humanitarian programs and it may still have to be used as a salvage procedure used in modern foot surgery. Our extensive experience with these deformities has been on global humanitarian programs.The adolescent neglected clubfoot is mostly treated in humanitarian programs by those with a great deal of surgical experience. This deformity needs a major correction, which can compromise the blood circulation and wound healing. A bony correction is preferable over an isolated soft tissue release. The extreme Lambrinudi arthrodesis with a double incision is therefore a preferred tool to correct a neglected clubfoot.This article describes the 3 main surgical options for correction of congenital brachymetatarsia in childhood. The one-stage lengthening by lengthening osteotomy and lengthening with graft interposition are suitable for defects less than 10 mm. For the greater defects from 10 mm to more than 20 mm, gradual lengthening by callus distraction with an external or internal fixator is appropriate. Over the last years, callus distraction with an internal minifixator became commonly established because of the significantly improved aftercare with early full weight-bearing and high postoperative comfort for the child. All 3 surgical procedures are presented with comprehensive image material.Every child with a neuromotor disorder is at risk for the development or a deterioration of foot deformities. This relates to central and peripheral diseases. Almost any kind of deformity may occur. As the basic problems mostly remain, a multidisciplinary team care program is necessary in addition to surgical management of the feet. Surgery must respect any muscle imbalance as well as joint deformities and instabilities. Postoperative orthotic support supplements most treatments. Long-term follow-ups are strongly advised to detect any recurrences or overcorrections.Children with cerebral palsy frequently develop foot deformities, most commonly equinus contractures, which can be managed with orthotics up to age 5 to 7 years. Plantar flexor lengthening, typically around this age, should be restricted to the offending muscle only, usually with a fascia release of the gastrocnemius. Equinovarus, mainly a problem in children with unilateral cerebral palsy, often responds to plantar flexor lengthening. If further tendon transfers are needed, they should be done when the child is older to avoid overcorrection. Planovalgus mostly improves spontaneously up to age 5 years. Surgical correction is best done in adolescence.The Ponseti method for treatment of congenital clubfoot is well established and has been introduced in most pediatric orthopedic centers worldwide. However, reported rates of recurrence are largely variable and open joint surgery is still performed frequently, even in the age group younger than 6 years of age. Preventing recurrence and residual deformity can be achieved by strict adherence to the Ponseti method, ensuring and enforcing brace compliance, frequent follow-up, and early treatment of recurrence. This review discusses reasons for clubfoot recurrence, prevention of clubfoot recurrence, and the treatment of recurrent congenital clubfoot within the realm of the Ponseti method.Clostridium (Clostridioides) difficile infection (CDI) causes significant morbidity and mortality in the United States every year. Prevention of CDI is difficult because of spore durability and requires implementation of multipronged strategies. Two categories of prevention strategies are infection control and prevention and risk factor reduction. Hand hygiene, contact precautions, patient isolation, and environmental decontamination are cornerstones of infection control and prevention. Risk factor reduction should focus on antibiotic stewardship to reduce unnecessary antibiotic use. If CDI incidence remains higher than the institution's goal despite these measures, then special measures should be considered.Multidrug-resistant gram-negative bacteria (MDR-GNB) pose one of the greatest challenges to health care today because of their propensity for human-to-human transmission and lack of therapeutic options. Containing the spread of MDR-GNB is challenging, and the application of multifaceted infection control bundles during an evolving outbreak makes it difficult to measure the relative impact of each measure. This article will review the utility of various infection control measures in containing the spread of various MDR-GNB and will provide the supporting evidence for these interventions.Vancomycin-resistant enterococcus (VRE) is a pathogen of growing concern due to increasing development of antibiotic resistance, increasing length of hospitalizations and excess mortality. The utility of some infection control practices are debatable, as newer developments in infection prevention strategies continued to be discovered. This article summarizes the significance of VRE and VRE transmission, along with highlighting key changes in infection control practices within the past 5 years.Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of health-care-associated infections. Controversies regarding the effectiveness of various control strategies have contributed to varying approaches to MRSA control. However, new evidence from large-scale studies has emerged, particularly concerning screening and decolonization. Importantly, implementation and outcomes of control measures in practice are not only influenced by scientific evidence, but also economic, administrative, and political factors, as demonstrated by decreasing MRSA rates in a number of countries after concerted and coordinated efforts at a national level. Flexibility to adapt measures based on local epidemiology and resources is essential for successful MRSA control.Surgical site infections (SSIs) are among the most common and most costly health care-associated infections, leading to adverse patient outcomes and death. Wound contamination occurs with each incision, but proven strategies exist to decrease the risk of SSI. In particular, improved adherence to evidence-based preventive measures related to appropriate antimicrobial prophylaxis can decrease the rate of SSI. Aggressive surgical debridement and effective antimicrobial therapy are needed to optimize the treatment of SSI.The Centers for Disease Control and Prevention shifted the focus of safety surveillance in mechanically ventilated patients from ventilator-associated pneumonia to ventilator-associated events in 2013 to increase the objectivity and reproducibility of surveillance and to encourage quality improvement programs to focus on preventing a broader array of complications. Ventilator-associated events are associated with a doubling of the risk of dying. Prospective studies have found that minimizing sedation, increasing spontaneous awakening and breathing trials, and conservative fluid management can decrease event rates and the duration of ventilation. Multifaceted interventions to enhance these practices can decrease ventilator-associated event rates.Catheter-associated urinary tract infection (CAUTI) remains one of the most prevalent, but preventable, health care-associated infections and predominantly occurs in patients with indwelling urinary catheters. Duration of urinary catheterization is the most important modifiable risk factor for development of CAUTI. Alternatives to indwelling catheters should be considered in appropriate patients. If indwelling catheterization is necessary, proper aseptic practices for catheter insertion and maintenance and use of a closed catheter collection system are essential for preventing CAUTI. The use of intervention bundles and collaboratives helps in the effective implementation of CAUTI prevention measures.Despite a large volume of research in prevention, central line-associated bloodstream infections and catheter-related bloodstream infections continue to cause significant morbidity, mortality, and increased health care costs. Strategies in prevention, including decision about catheter placement, insertion bundles, adherence to standard of care guidelines, and technologic innovations, shown to decrease rates of catheter-related bloodstream infections and central line-associated bloodstream infections are described in this update. The coronavirus disease 2019 pandemic has resulted in increased health care-acquired infections, including central line-associated bloodstream infections.Pandemic preparedness is a key function of any health care facility. Activities pertaining to pandemic preparedness should be developed and maintained within a broader emergency management plan. The use of a Hospital Incident Command System can centralize coordination of the response and facilitate internal and external communication. This review addresses several components of pandemic preparedness, including incident management, health care personnel safety, strategies to support ongoing clinical activities, and organizational communication during a pandemic. Preparations addressing potential ethical challenges and the psychological impact associated with pandemic response are also reviewed.Health care-acquired viral respiratory infections are common and cause increased patient morbidity and mortality. Although the threat of viral respiratory infection has been underscored by the coronavirus disease 2019 (COVID-19) pandemic, respiratory viruses have a significant impact in health care settings even under normal circumstances. Studies report decreased nosocomial transmission when aggressive infection control measures are implemented, with more success noted when using a multicomponent approach. Influenza vaccination of health care personnel furthers decrease rates of transmission; thus, mandatory vaccination is becoming more common. click here This article discusses the epidemiology, transmission, and control of health care-associated respiratory viral infections.
