BACKGROUND: Natural history of disease refers to the progression of a disease process in an individual over time, in the absence of treatment. Understanding natural history of tendinopathies is key for clinicians to make accurate prognostic predictions and design effective intervention studies.
OBJECTIVE: To quantify the natural history of the main tendinopathies regarding pain and function and to compare outcomes between untreated individuals and those receiving treatment.
METHODS: A systematic literature search was conducted until February 2023, across PubMed, Cochrane, Embase and Scopus databases. Selection criteria included randomized controlled trials (RCTs) with a \"wait-and-see\" group and cohort studies with ≥3 months of follow-up reporting on pain and function-related outcomes. Standardized mean differences (SMDs) of \"wait-and-see\" groups were pooled using a random-effects inverse-variance model. Risk of bias was assessed using Cochrane Risk-of-Bias (RoB2), and quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach.
RESULTS: Six RCTs were included, encompassing 518 subjects with tendinopathy. Pooled results demonstrated significant pain (SMD = 0.30, 95%CI: 0.19-0.41) and physical function improvement (SMD = 0.38, 95%CI: 0.28-0.48). These estimates remained consistent regardless of age or follow-up duration. In rotator cuff tendinopathy, untreated individuals improved but did not fully recover at one year, with similar outcomes to other interventions (e.g., surgery). Subjects with lateral elbow, patellar and achilles tendinopathies when untreated, did not fully resolve symptoms within 12-16 weeks.
CONCLUSIONS: This review provides limited conclusions about natural history of tendinopathies. Future studies should incorporate true no-intervention groups to accurately reflect tendinopathy\'s natural progression.

The aim of this study was to examine how the \"wait-and-see\" recommendation affects adolescents\' understanding of their illness and symptoms and their care-seeking behavior.
This study included brief qualitative, semi-structured online interviews. Adolescents (age 10-19 years) with long-term knee pain, who had been recommended \"wait-and-see\" by their general practitioner (GP), were recruited via previous studies and social media. Two researchers conducted brief semi-structured interviews through Microsoft Teams. An interview guide with open questions was created prior to the interviews and updated as new questions emerged. The extracted data was transcribed and analyzed via a reflexive thematic approach in NVivo.
Eight adolescents (mean age 17.8) with longstanding or recurrent knee pain (mean duration 3.5 years) were included. The analysis identified four main themes: (1) The perception of wait and see over time, (2) The GP\'s acknowledgement and consideration, (3) experienced limitation from knee pain and (4) the importance of getting a diagnosis. The perception of \"wait-and-see\" approach changed from positive to negative when adolescents received the recommendation multiple times. Adolescents experienced frustration with their situation and a lack of consideration from their GP made them cautious about seeking additional care. Knee pain significantly limited the adolescents\' physical-and social activities. Receiving a diagnosis was important and helped adolescents dealing with their pain.
The connotation of wait-and-see changed from positive to negative for adolescents when receiving the recommendation multiple times. The participants felt getting a clinical diagnosis was a relief. Furthermore, the lack of consideration and acknowledgement from the GP plays an essential role in the adolescent\'s understanding of their knee pain.
Recommending adolescents to \"wait-and-see\" multiple times in relation to their knee problems can lead adolescents experience frustration and a lack of consideration from their GP. It would be advisable for GPs to provide adolescents with a diagnosis as it can facilitate them in dealing with their pain and to use simple language when explaining adolescents their condition to improve communication.

UNASSIGNED: Infantile haemangioma (IH) is the most common benign tumor in children. At present, pulsed dye laser (PDL) has made great progress in the treatment of superficial IH, showing good safety and effectiveness. But some doctors think that superficial IH should choose to wait-and-see. However, studies have reported that most of the IH after resolution still has residual disease, and thickness seems to be an important factor. Therefore, the purpose of this study is to investigate the relationship between Sequelae and thickness after superficial IH involution. In addition, compare the Sequelae difference between 595-nm pulsed laser combined with 755-nm long-pulse alexandrite laser treatment and wait-and-see.
UNASSIGNED: This retrospective observational study included patients with superficial IH evaluated in the past 6 years and divided them into a laser group and an observation group.
UNASSIGNED: The incidence of sequelae in the laser group was 44.6%, and the incidence of sequelae in the observation group was 69.5%. The incidence of Sequelae of superficial IH in the laser group was significantly lower than that in the observation group (χ 2-test, χ 2=10.790, P <0.001). In the observation group, the average A scores of the three thickness subgroups (<2mm, 2-5mm, and >5mm) were 4.38, 3.39, and 1.80, and there were significant differences in the A scores between the three groups (Kruskal-Wallis, p<0.05). There is a significant difference in the A score between the laser group and the observation group in the superficial IH with a thickness of 2-5 mm and>5mm (Wilcoxon rank sum test, P<0.05).
UNASSIGNED: This retrospective study showed that the degree of Sequelae of superficial IH after involution is related to its thickness. In addition, the early intervention of 595-nm pulsed laser combined with 755-nm long-pulse alexandrite laser can reduce the incidence and extent of sequelae.

Desmoid-Type Fibromatosis (DTF) is a rare mesenchymal neoplasm with a locally invasive pattern and high risk of local recurrence after surgery. Historically, the standard treatment for DTF was surgical resection. However, considering the difficulty of achieving surgical eradication, the possible unnecessary morbidity and the unpredictability of the natural history, a wait-and-see approach has been proposed for asymptomatic DTF.
We analyzed 87 consecutive patients with histologically-proven sporadic primary DTF, first recurrence or residual disease managed at our institution between 2000 and 2018. Patients and tumor-related variables were reviewed and analyzed. Two different treatment strategies were adopted according to different time periods: in the \"early period\" (2000-2010) patients underwent surgical treatment irrespective of the clinical presentation, whereas in the \"late period\" (2012-2018) asymptomatic patients used to undergo a wait-and-see strategy. The event-free survival (EFS) was compared trough a pre-post comparison.
In the early period, surgery was performed in 51 (94.4%) patients and watchful waiting in 3 (5.6%). In the late period, the watchful waiting group accounted for 24 (72.7%) patients and the surgical group for 9 (27.3%). No statistically independent prognostic factors were found. EFS did not show statistically significant differences between early and late period groups.
Wait-and-see policy has shown to be equivalent to upfront surgery in terms of EFS; therefore, a conservative approach is recommended in asymptomatic patients diagnosed with DTF that can be followed through watchful waiting.

Symptomatic atrial fibrillation (AF) is a common cause of emergency department (ED) referrals. In case of hemodynamic stability, the choice to either perform early cardioversion (pharmacologic or electrical) or to prescribe rate-lowering drugs and differ any attempts to restore sinus rhythm (i.e., wait-and-see approach) has been widely debated. Results of the recent Rate Control versus Electrical Cardioversion Trial 7-Acute Cardioversion versus Wait and See (RACE 7 ACWAS) have been considered a strong argument in favor of the wait-and-see approach. In this debate, we discuss several issues that would support early cardioversion, ranging from patients\' satisfaction and costs to concerns about safety. Furthermore, the wait-and-see approach may translate into a missed opportunity to encourage widespread use of a \"pill-in-the-pocket\" home treatment: this underused option could allow rapid solving of many AF episodes, potentially avoiding future ED referrals. Our opinion is that a delayed cardioversion may introduce unneeded complications in the straightforward management of a common clinical problem. Therefore, early cardioversion should continue to be the preferred option because of its proven efficacy, safety and convenience.

BACKGROUND: Among rectal cancer patients, some of good responders after neoadjuvant chemoradiotherapy (nCRT) are considered for non-operative treatments to avoid postoperative morbidities and permanent stoma. However, oncologic feasibility of non-operative treatment has not been fully understood.
METHODS: From 2008 to 2017, we retrospectively reviewed patient\'s records who had lower or mid rectal cancer and diagnosed to clinical complete response by magnetic resonance imaging after nCRT. Clinical differences and oncologic outcomes were compared among Radical surgery (RS), Local excision (LE) and Wait-and-see (WS) group.
RESULTS: Number of 129, 25, 15 patients included to RS, LE, WS groups. Local recurrence was frequent type of recurrence in both of LE and WS group (RS; 31.3%, LE; 80%, WS; 66.7%), and many patients in WS group omitted salvage treatment (RS; 75%, LE; 100%, WS; 33.3%). 5-years local-recurrence/disease-free survival rate (LRFS, DFS) between RS and LE were similar between each group, but WS showed significantly inferior outcomes than that of RS (LRFS; p = 0.001, DFS; p = 0.001). In multivariate analysis, WS protocol (OR; 7.163, 95% CI; 1.995-25.715) and cT4 stage (OR; 8.206, 95% CI; 1.596-42.198) were independent factors for LRFS.
CONCLUSIONS: Wait-and-see group showed high rate of rejection of salvage treatments for recurrence, and poor oncologic outcomes. However, recent low-level evidences reported favorable outcome of WS protocol when salvage treatment was followed after recurrence. It seems that the application of WS protocol should be postponed until the results of randomized-controlled trials are available. Local excision seems to be good alternative option to radical surgery when salvage treatment is followed.

From a speech-language pathology perspective, there is a gap in interprofessional education/practice (IPE/IPP) that leads to a wait-and-see approach with late talkers (LT). In line with the American Speech-Language-Hearing Association\'s Strategic Pathway to Excellence, this article attempts to bridge the gap, reexamining the panoptic view that most LT \"catch up\" to their peers. The LT who persist with language disorder should not be overlooked. Late talking can impact socialization and school readiness, and can place some toddlers at risk for life-long disability. Each state\'s early intervention program has an established IPP infrastructure. Parent-implemented intervention addresses risks and maximizes protective factors.

BACKGROUND: Asymptomatic diaphragmatic hernia is generally thought to be rare among adults. We present two different types of asymptomatic diaphragmatic hernia diagnosed with computed tomography (CT) and discuss treatment strategies.
METHODS: Case 1: A 37-year-old woman was diagnosed with catamenial pneumothorax in the right diaphragm. Partial resection of the diaphragm and lung was performed using a linear stapler. She was asymptomatic after the operation and gave birth 2 years later. After delivery, she experienced recurrent pneumothorax, and CT revealed a right diaphragmatic defect with herniation of a part of the liver into the thorax. An iatrogenic diaphragmatic hernia was diagnosed. There has been no change in the size of the hernia and no symptoms due to the diaphragmatic hernia for more than 3 years after it was diagnosed. Case 2: A 75-year-old woman was previously diagnosed with rectal cancer and had undergone surgery after chemoradiotherapy. One year after surgery, herniation of a 3 × 1.3-cm section of retroperitoneal fat tissue into the left thoracic cavity was observed incidentally at a follow-up CT and was diagnosed as an adult Bochdalek hernia (BH). We reviewed the patient\'s past CT findings and confirmed that the same finding had been present since the first scan. A wait-and-see approach was chosen because there had been no change in the size of hernia, there were no symptoms, the patient was elderly, and there was a high risk of recurrence of the rectal cancer. She has had no symptoms to date, and careful follow-up has been performed.
CONCLUSIONS: There are few reports of asymptomatic adult diaphragmatic hernia. Although symptomatic diaphragmatic hernia is generally treated surgically, there are cases in which a wait-and-see approach has been applied, such as our asymptomatic cases.

The efficacy of the classical treatment modalities surgery and radiotherapy in the treatment of aggressive fibromatosis is presently disputed and there is a shift towards a more conservative approach. The aim of the present study is to objectify tumor growth in patients with extra-abdominal or abdominal wall aggressive fibromatosis, while adhering to a \"watchful waiting\" policy. Other objectives are to investigate quality of life and to identify factors associated with tumor growth, in particular the relation with the presence of a CTNNB1-gene mutation in the tumor.
GRAFITI is a nationwide, multicenter, prospective registration trial. All patients with extra-abdominal or abdominal wall aggressive fibromatosis are eligible for inclusion in the study. Main exclusion criteria are: history of familiar adenomatous polyposis, severe pain, functional impairment, life/limb threating situations in case of progressive disease. Patients included in the study will be treated with a watchful waiting policy during a period of 5 years. Imaging studies with ultrasound and magnetic resonance imaging scan will be performed during follow-up to monitor possible growth: the first years every 3 months, the second year twice and the yearly. In addition patients will be asked to complete a quality of life questionnaire on specific follow-up moments. The primary endpoint is the rate of progression per year, defined by the Response Evaluation Criteria In Solid Tumors (RECIST). Secondary endpoints are quality of life and the rate of influence on tumor progression for several factors, such as CTNNB1-mutations, age and localization.
This study will provide insight in tumor behavior, the effect on quality of life and clinicopathological factors predictive of tumor progression.
The GRAFITI trial is registered in the Netherlands National Trial Register (NTR), number 4714 .

Wait-and-see treatment strategies may benefit rectal cancer patients who achieve a clinical complete response (cCR) after neoadjuvant chemoradiotherapy (NCRT). In this study, we analyzed data from 9 eligible trials to compare the oncologic outcomes of 251 rectal cancer patients achieving a cCR through nonsurgical management approaches with the outcomes of 344 patients achieving a pathologic complete response (pCR) through radical surgery. The two patient groups did not differ in distant metastasis rates or disease-free and overall survival, but the nonsurgical group had a higher risk of 1, 2, 3, and 5-year local recurrence. Hence, we concluded that for rectal cancer patients achieving a cCR after NCRT, a wait-and-see strategy with strict selection criteria, an appropriate follow-up schedule, and salvage treatments achieved outcomes at least as good as radical surgery. Long-term randomized and controlled trials with more uniform inclusion criteria and standardized follow-up schedules will help clarify the risks and benefits of wait-and-see treatment strategies for these patients.
