Background: Congenital absence of the pericardium (CAP) is a rare cardiac abnormality. As pericardial defects are usually asymptomatic, most cases are diagnosed during surgery or on autopsy. The patient in this case was found to have CAP during thoracoscope. Case: We present the unusual case of a 69-year-old patient with CAP who experienced sudden ventricular arrhythmia and developed ventricular fibrillation during left upper lobectomy. Surgical operations, the lateral decubitus position, and other external stimuli may be important risk factors for ventricular fibrillation. The patient regained sinus rhythm soon after intrathoracic cardiac compression and pharmacological treatment, including lidocaine spray (2%, 10 ml) administered to the heart surface. The surgery was then completed without any additional instances of ventricular arrhythmia. Conclusions: Patients with CAP are more susceptible to cardiac-related adverse events during thoracotomy or thoracoscopy. Treatment of ventricular arrhythmias that occur during lung resection in patients with CAP should be emphasized. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the influence of the initial clinical presentation (symptomatic vs. asymptomatic) on histopathological tumor features in patients with upper tract urothelial carcinoma (UTUC). Methods: We conducted a single-center, cross-sectional, and retrospective study that enrolled 72 adults with primary UTUC who underwent radical nephroureterectomy at our institution over a period of 4 years (April 2019–April 2023). Results: Symptomatic patients exhibited significantly higher frequencies of high-grade UTUC (73.6% vs. 36.8%, p = 0.006), ≥ T2 stage UTUC (60.4% vs. 26.3%, p = 0.007), and larger tumor sizes (median 5 vs. 4 cm, p = 0.015) compared to asymptomatic patients. Multiple regression analyses demonstrated significant associations between symptomatic presentation and the presence of high-grade UTUC (OR 6.35, 95% CI 1.81–22.27, p = 0.004), ≥ T2 stage UTUC (OR 5.98, 95% CI 1.62–22.08, p = 0.007), and larger tumor size (B 3.14, 95% CI 0.62–5.66, p = 0.015). A subset of patients with hematuria was separately analyzed to assess the influence of hematuria severity (gross vs. microscopic) on UTUC characteristics. Patients with gross hematuria exhibited significantly higher frequencies of high-grade UTUC (72.9% vs. 33.3%, p = 0.048) and ≥ T2 stage UTUC (58.3% vs. 22.2%, p = 0.001). Multiple regression analyses showed significant associations between gross hematuria and the presence of high-grade UTUC (OR 6.34, 95% CI 1.15–34.95, p = 0.034) and ≥ T2 stage UTUC (OR 6.54, 95% CI 1.11–38.93, p = 0.039). Conclusion: Initial symptomatic presentation was independently associated with adverse histopathological UTUC characteristics, potentially attributed to earlier detection of UTUC in asymptomatic patients, before the onset of symptoms.

Background: While it has been demonstrated that large asymptomatic pulmonary embolism (PE) can occur, many studies have assessed inpatients or patients with known risk factors for venous thromboembolism (such as malignancy). There are few data regarding incidental PE in outpatients with deep vein thrombosis (DVT) or assessing whether these emboli occur centrally or peripherally in the pulmonary arteries. Aims: To determine the rates of incidental central and peripheral PE in outpatients with proximal and distal DVT. Methods: This was a retrospective cross‐sectional study of 120 patients attending our community imaging clinic between January 2015 and March 2020, with ultrasound‐confirmed lower limb DVT, and subsequent computed tomography pulmonary angiogram (CTPA) within 24 h. Exclusion criteria were symptoms indicative of PE. Imaging reports were retrospectively reviewed to record the proximity of DVT and the location of any PE as either central (pulmonary trunk or main pulmonary arteries) or peripheral (lobar, segmental or subsegmental pulmonary arteries). Results: Incidental PE occurred in 71 patients (59.2%), with a rate of 77.5% in proximal and 50.0% in distal DVT. Sixteen patients had central PE (13.3% of all patients with DVT; 22.5% of all patients with PE). Two patients (both with proximal DVT) had PE in the pulmonary trunk. Conclusions: Incidental PE occur frequently in outpatients with lower limb DVT, including the possibility of asymptomatic central emboli. Further studies with larger patient cohorts would be useful to assess the utility of baseline chest imaging in outpatients with DVT. [ABSTRACT FROM AUTHOR]

Background: Current guidelines recommend treating choledocholithiasis, regardless of symptoms or stone size, with endoscopic retrograde cholangiopancreatography (ERCP). However, asymptomatic choledocholithiasis, discovered incidentally on imaging, may carry a higher risk of ERCP-related adverse events, and some asymptomatic and diminutive stones may not cause biliary adverse events during extended follow-up. Therefore, we aimed to clarify the best treatment strategies for asymptomatic choledocholithiasis based on stone size. Methods: We retrospectively identified patients with incidental imaging-found asymptomatic diminutive (≤ 4 mm) or non-diminutive (> 4 mm) choledocholithiasis and divided them into two groups: those who did not undergo ERCP and were treated when complications arose (on-demand group) and those who underwent ERCP before being symptomatic (intervention group). Adverse events were defined as any biliary or pancreatic complication related to ERCP or arising during observation or after intervention. The primary outcome was the adjusted overall adverse event-free survival using the propensity score-based matching weights method comparing the two groups of stone size. Results: Among 148 patients identified (median follow-up period, 969 days), 68 had diminutive stones and 80 had non-diminutive stones. Of the 68 patients with diminutive stones, 51 were in the on-demand group and 17 in the intervention group. The overall adjusted adverse event-free survival was significantly higher in the on-demand group for diminutive stones (97.4% and 70.1%, respectively, at 3 years; p = 0.01). Discussion: Patients with incidental imaging-detected asymptomatic diminutive choledocholithiasis may benefit from clinical observation, pursuing ERCP when symptoms develop. [ABSTRACT FROM AUTHOR]

This study investigated the impact of the initial clinical presentation of bladder cancer on tumor characteristics. A cross-sectional, retrospective study was performed, and it involved 515 patients who underwent transurethral bladder cancer resection at the University Hospital Center Split between April 2019 and April 2023, excluding recurrent cases. The association between symptomatic versus asymptomatic presentation and bladder cancer characteristics was analyzed. A subgroup analysis compared tumor characteristics between patients with gross and microscopic hematuria. Multiple regression analyses revealed a significant association between symptomatic presentation and the detection of high-grade bladder cancer (OR 3.43, 95% CI 2.22–5.29, p < 0.001), concomitant CIS (OR 3.41, 95% CI 1.31–8.88, p = 0.012), T2 stage bladder cancer (OR 5.79, 95% CI 2.45–13.71, p < 0.001), a higher number of tumors (IRR 1.24, 95% CI 1.07–1.45, p = 0.005), and larger tumor size (B 1.68, 95% CI 1.19–2.18, p < 0.001). In the subgroup analysis, gross hematuria was associated with the detection of high-grade bladder cancer (OR 2.07, 95% CI 1.12–3.84, p = 0.020), T2 stage bladder cancer (OR 6.03, 95% CI 1.42–25.49, p = 0.015), and larger tumor size (B 1.8, 95% CI 0.99–2.6, p < 0.001). The identified associations between symptomatic presentation and unfavorable bladder cancer characteristics, likely attributed to early detection in asymptomatic cases, underscore the importance of additional research in the development of bladder cancer screening strategies.

Background: In cases of chronic otitis media (COM) presenting with unilateral squamosal disease, there may be the possibility of a potential disease in the opposite ear, which may lead to future complications. Therefore, it needs to be known whether there is any silent pathological process in the contralateral ear (CLE) that is currently asymptomatic but likely to be diseased in the near future. Therefore, this study was undertaken to analyze the fate of the contralateral asymptomatic ear in patients with unilateral squamosal disease. Results: A total of 32 patients with COM squamosal disease were included. All the patients were subjected to clinical examination and a high-resolution computed tomography (CT) scan of bilateral temporal bones. The mean duration of age at presentation was 20.4 years. The male-to-female ratio was 1.28. Out of 32 patients, 11 (34%) showed either clinical or radiological findings in the asymptomatic CLE, out of which 7 showed both abnormal clinical and radiological findings, 3 demonstrated only abnormal clinical findings, and 1 showed only abnormal CT changes without obvious clinical findings in the CLE. In the CLE, 7 (21%) patients had mild conductive hearing loss. There was no statistically significant association of clinical findings or radiological findings in CLE to that of the unilateral squamosal diseased ear. Conclusion: In cases with unilateral squamosal disease, an asymptomatic CLE can undergo subclinical changes and conductive hearing loss. Patients can also have silent radiological changes in the CLE detected on the CT scan, which are significant but remain undetected. No statistical significance could be reported in this study, yet other studies with even larger samples are required to show a causal relation between unilateral squamosal disease and a quiescent process in the asymptomatic CLE.

Purpose: This study aimed to compare the characteristics of asymptomatic and symptomatic nephrolithiasis in patients who underwent surgical treatment for kidney stones. Materials and Methods: Between 2015 and 2019, 245 patients who underwent percutaneous nephrolithotomy or retrograde intrarenal surgery for kidney stones were included. The patients were divided into asymptomatic (n=124) and symptomatic (n=121) groups. All patients underwent blood and urine tests, preoperative non-contrast computed tomography, and postoperative stone composition analysis. We retrospectively analyzed and compared the characteristics of the patients and stones, operation time, stone-free rate, and postoperative complications between the two groups. Results: In the asymptomatic group, mean body mass index (BMI) was significantly higher (25.7±3.8 kg/m² vs. 24.3±2.8 kg/m², p=0.002) and urine pH was significantly lower (5.6±0.9 vs. 5.9±0.9, p=0.013). The ratio of calcium oxalate dihydrate stones was significantly higher in the symptomatic group (5.3% vs. 15.5%, p=0.023). No significant differences were observed in stone characteristics, postoperative outcomes, or complications. In the multivariate logistic regression analysis for predicting variables for asymptomatic renal stones, BMI (odds ratio [OR], 1.144; 95% confidence interval [CI], 1.038-1.260; p=0.007), and urine pH (OR, 0.608; 95% CI, 0.407-0.910; p=0.016) were independent predictive variables for asymptomatic renal stones. Conclusions: This study demonstrated that thorough medical check-ups are needed for the early detection of renal stones in individuals with a high BMI or low urine pH. [ABSTRACT FROM AUTHOR]

Most publications on pediatric COVID-19 in Spain were performed at the beginning of the pandemic when some diagnostic tools were not widely available. This study aims to show the real spectrum of the infection based on wide detection of cases due to symptoms and contact tracing. A descriptive and analytical observational study was performed including pediatric cases (0 to 14 years) from the region of Aragón between May 12 and October 31, 2020. Diagnostics was by PCR detection of viral RNA, rapid antigen detection test, or positive IgG serology. There were 5933 positive children included. Of them, 49.03% were women. The mean age was 7.53 ± 4.28 years. The source of infection could not be determined in 17.8% of cases. As for the rest, was determined to be within the family environment in 67.8%. The percentage of asymptomatic patients was 50.3%. Among symptomatic patients, fever (58.1%) and cough (46.7%) were the most frequent symptoms. Hospitalization was required in 0.52% of infected, intensive care unit admission was on 0.05%, and there was one death (0.02%). Children under the age of one presented some symptoms more frequently (71.6% vs 48.5%; OR 2.68; 95% CI 2.08 to 3.45; p < 0.001) and required more hospitalizations (3.9% vs 0.34%; OR 11.52; 95% CI 5.65 to 23.52; p < 0.001). Conclusion: In our environment, SARS-CoV-2 infection is like other mild respiratory viral infections in the population under the age of 15. The contagion occurs mainly in the family environment, the number of asymptomatic is high, being the symptoms mild and the complications very infrequent. What is Known: • Pediatric infection produced by SARS-CoV-2 has manifested as a mild disease in relation to adult age, although with higher affectation at the youngest ages. • Nearly all studies on epidemiology and clinical spectrum of the disease were conducted with patients diagnosed at the beginning of the pandemic. By then, diagnostic tools were only available in hospitals and in emergency units. What is New: • Once diagnostic means were available in primary care medicine and were used not only for the diagnosis of clinical symptoms of the patient, but for the tracing of case contacts, a much more precise approach to the epidemiology and clinical manifestations of the disease was allowed, as described in this study.

Purpose: Compression of the iliac vein between the iliac artery and lumbosacral vertebra can cause iliac vein compression syndrome (IVCS). The purpose of this study is to assess compression characteristics and establish a new sub-typing in asymptomatic IVCS individuals using contrast-enhanced CT. Methods: A retrospective analysis of abdomen contrast-enhanced CT images from 195 asymptomatic subjects with iliac vein compressed was investigated. Patients had no history of venous pathology, and images were collected from June 2018 to January 2019. Qualitative and quantitative characteristics of compression were examined including the location, pattern, minor diameter, area, and the percentage compression on an orthogonal section by the post-processing of multiple planar reconstruction and volume rendering. Results: There were 107 females and 88 males with age range 18–92 years. The most common site of iliac vein compression was localized to the left common iliac vein (LCIV) (178/195, 91.3%). Notably, four compression types (type I–IV) were established according to the compression location, with type II being the most common. The four compression types had differences in the upper limit and fluctuation range of compression. It was found that the average level of iliac vein compression was below 25%. The compression degree of the left common iliac vein in type II was relatively concentrated, and the upper limit of compression was close to 70%. Conclusion: Asymptomatic iliac vein compression was categorized according to compression location. The proposal of four types might help clinicians to predict which IVCS patients would benefit from interventional therapy. [ABSTRACT FROM AUTHOR]

We determined secondary attack rates (SAR) among close contacts of 59 asymptomatic and symptomatic coronavirus disease case-patients by presymptomatic and symptomatic exposure. We observed no transmission from asymptomatic case-patients and highest SAR through presymptomatic exposure. Rapid quarantine of close contacts with or without symptoms is needed to prevent presymptomatic transmission. [ABSTRACT FROM AUTHOR]

Primary cardiac tumors, such as myxomas, are rare. About 75% of myxomas occur in the left atrium of the heart. Myxomas can have a broad clinical spectrum. The clinical presentation varies from asymptomatic to sudden cardiac death. Sometimes, a diagnosis is difficult. Cardiac myxoma can cause hemodynamic disturbances in the setting of pneumonia and hypercoagulable state in patients with Coronavirus disease 2019(COVID-19) and make treatment decisions difficult. We present a case of unusually huge left atrial mass discovered incidentally in a patient with COVID-19. Upon workup, an echocardiogram revealed an incidental 7 × 5 cm left atrial myxoma. Preoperatively, the patient was monitored closely in the ICU. After stabilization in the ICU, the patient was taken to surgery and the tumor was successfully removed. Pathohistological results after surgical removal of the tumor confirmed the diagnosis of cardiac myxoma. We consider our case extremely rare due to the asymptomatic course despite the large size of the tumor. [ABSTRACT FROM AUTHOR]

Claudication of the young patient is a very rare symptom for orthopaedic surgeons and it is often overlooked. We report a rare case of popliteal artery entrapment syndrome (PAES), discovered during a vascular claudication following posttraumatic anterior instability of the knee. The diagnosis was confirmed by CT angiography which showed a PAES, with a pathway in the intercondylar notch. The patient had a releasing of the trapped vessel by myomectomy, with disappearance of vascular symptoms six months later. Through this case, we wanted to draw the attention of orthopaedic surgeons to the fact that the PAES can be asymptomatic. Its symptomatology can be triggered by a traumatic instability of the knee. Its presence represents a risk of lesion of the popliteal artery during arthroscopic ACL reconstruction. Therefore, it is important to think about this disease if a calf pain occurring after a ligament injury of the knee. [ABSTRACT FROM AUTHOR]

Hemodialysis catheter fracture with distal embolization is a rare complication. The natural process of retained asymptomatic hemodialysis is unclear. This is a report of an iatrogenic fracture of the tip of the hemodialysis catheter in an adult patient who was successfully retrieved using an image-guided endovascular technique. In the event of catheter fracture with distal embolization, percutaneous retrieval is the treatment of choice. [ABSTRACT FROM AUTHOR]

Background: There is a growing awareness that prevention and early diagnosis may reduce the high mortality associated with cancer, cardiovascular and other diseases. The role of whole-body computed tomography (WB-CT) in self-referred and asymptomatic patients has been debated. Aim: To determine frequency and spectrum of WB-CT findings in average-risk subjects derived from a Medical-Check-Up-Unit, to evaluate recommendations reported and distribution according to sex and age-groups. Materials and methods: We retrospectively reviewed 6516 subjects who underwent WB-CT (June 2004/February 2015). All were > 40 years and referred by Medical-Check-Up-Unit of our hospital. The main findings were categorized and classified as normal or not. Its distribution according to sex and age-groups was evaluated using Chi-square test and linear-by-linear association test, respectively. Number of recommendations, type and interval of follow-up were recorded. Descriptive statistics were used. Results: WB-CT performed in 6516 patients (69% men, 31% women, mean age = 58.4 years) revealed chest (81.4%), abdominal (93.06%) and spine (65.39%) abnormalities. Only 1.60% had completely normal exploration. Abnormal WB-CT in men was significantly higher than women (98.64% vs. 97.87%; p = 0.021), with significant increase as age was higher (40–49 years: 95.65%; 50–59 years: 98.33%; 60–69 years: 99.47%; > 69 years: 99.89%) (p < 0.001). Although most findings were benign, we detected 1.47% primary tumors (96, mainly 35 kidneys and 15 lungs). 17.39% of patients received at least one recommendation predominantly in chest (78.19%) and follow-up imaging (69.89%). Conclusion: The most common WB-CT findings in asymptomatic subjects are benign. However, this examination allows identifying an important number of relevant and precocious findings that significantly increase with age, involving changes in lifestyle and precocious treatment.

Background: Previous studies suggested that patients with symptomatic intervertebral disc degeneration (IDD) of lumbar spine have reduced cross-sectional area (CSA) and functions of core muscles. However, reduced CSA and functions of core muscles have been observed not only in patients with symptomatic IDD but also in patients with other subgroups of low back pain (LBP). Thus, it is uncertain whether reduced CSA and functions of core muscles lead to IDD and LBP, or pain leads to reduced CSA and functions of core muscles in patients with symptomatic IDD. Therefore, this study aimed to compare the CSA and functions of core muscles between asymptomatic participants with and without IDD in magnetic resonance imaging (MRI).Methods: Twenty asymptomatic participants (12 men and 8 women) participated in this study. Ten participants had asymptomatic IDD at L4-5. The others were healthy controls (without IDD at all levels of lumbar spine). The CSA of core muscles was measured using MRI. Maximal isometric trunk flexor strength and side bridge strength were measured by a Smart KEMA strength sensor. Trunk flexor endurance test, side bridge endurance test and plank endurance test were used to measure core endurance. Double legs loading test was used to measure core stability. Mann-Whitney U test was used to compare the differences between two groups.Results: There were no significant differences in core muscle functions between the two groups (p > 0.05). Moreover, there was no significant difference in CSA between the two groups (p > 0.05).Conclusions: There was no significant difference in CSA and core muscle functions between asymptomatic participants with and without IDD. These findings indicate that a degenerative or bulging disc in asymptomatic individuals has little effect on CSA and functions of core muscles, especially in young age. Therefore, the general core endurance test or strength test could not differentiate asymptomatic people with and without IDD of lumbar spine.Trial Registration Number: Clinical Research information Service.

Background: Laparoscopic sleeve gastrectomy (LSG) has become the most frequently performed bariatric procedure to date. However, LSG is known to worsen pre-operative and result in de novo gastroesophageal reflux disease (GERD). Pre-operative evaluation reveals a high percentage of silent GERD of so far unknown influence on post-operative GERD.Methods: Prospective data of patients undergoing primary LSG between 01/2012 and 12/2015 were evaluated. Pre-operative GERD-specific evaluation consisted of validated questionnaires, upper endoscopy, 24 h-pH-manometry, and esophagograms. Patients were followed-up with questionnaires every 6 months, upper endoscopies after 1 year and 24 h-pH-metry after 2 years. Silent GERD was defined as esophagitis grade > B and/or abnormal esophageal acid exposure in absence of symptoms. LSG was performed over a 32F bougie, hiatal hernias > 1 cm were addressed with posterior hiatoplasty. Excluded were patients with hiatal hernias > 4 cm, patients with incorrect anatomy (stenosis, fundus too large) and conversion to RYGB for early leaks.Results: 222 patients were included. Mean follow-up was 32 ± 16 months, mean preoperative body mass index 49.6 ± 7.2 kg/m2. 116 patients (52%) presented with post-operative GERD-symptoms, of which 85 (73%) had de novo symptoms. Of those, 48 (of 85, 56%) had no preoperative GERD and 37 (of 85, 44%) silent GERD. 57 patients (26%) had neither pre- nor post-operative GERD, 7 (3%) had silent pre-operative and no postop GERD, and in 19 patients (9%) GERD was cured with LSG. 31 patients (14%) stayed symptomatic. Of 56 patients (25%) with pre-operative silent GERD, 37 (of 54, 66%) became symptomatic.Conclusion: LSG leads to a considerable rate of post-operative GERD. De novo-GERD consist of around half of pre-operative silent GERD and completely de novo-GERD. Most patients with pre-operative silent GERD became symptomatic. [ABSTRACT FROM AUTHOR]

Objective: The assessment of individuals from families affected by familial frontotemporal dementia (FTD) allows the evaluation of preclinical or pre-diagnosis disease markers. The current work aims to investigate the existence of a cognitive phase in GRN mutation carriers before overt clinical symptoms begin. Methods: We performed a longitudinal neuropsychological analysis (three assessments in 4 years) in a group of presymptomatic c .7 0 9 -1G > A progranulin (GRN) (n = 15) mutation earners and non-camer relatives (n = 25) from seven FTD families. Results: GRN mutation carriers showed subtle decline over the longitudinal follow-up in several different domains (namely, attention, facial affect recognition, decision-making, language, and memory). The differences between groups were most marked in the facial affect recognition test, with improvement in the non-carrier group and decline in the GRN mutation earner group, with very large effect sizes. Conclusions: Facial affect recognition may decline before clinical diagnosis and makes the adapted version of the Picture of Facial Affect a potential candidate for early detection of GRY-associated FTD.

Objective: Challenging differential diagnosis Background: Acute coronary syndrome (ACS) is a common and potentially life-threatening condition encountered in emergency departments. Despite its dreaded nature, nearly one-third of ACS present without chest pain and may mislead clinicians. Additionally, Wellens' syndrome is a pre-infarction stage of significant proximal left anterior descending (LAD) artery stenosis, which can lead to extensive anterior wall myocardial infarction without timely intervention. Case Report: We report the case of a 74-year-old woman presenting with isolated throat pain and Wellens' pattern in the initial EKG, which prompted the proper workup and management. Subsequently, coronary angiogram revealed more than 90% occlusion of the proximal LAD artery, and a drug-eluting stent was deployed. The patient did well after the procedure and the follow-up at 2 weeks after discharge was uneventful. Conclusions: This case highlights the importance of awareness of atypical presentation of ACS and importance of Wellens' syndrome. We also discuss the incidence of craniofacial symptoms of ACS, and the epidemiology, pathophysiology, management, and prognosis of Wellens' syndrome. [ABSTRACT FROM AUTHOR]

Background. The biggest challenge today is the accuracy of diagnostic tools to detect asymptomatic malaria. Up to the present, a microscopic examination procedure is only performed on patients with fever; thus, finding asymptomatic malaria is quite impossible. A serial microscopic examination (SME) procedure on patients who are at risk of malaria would make it possible to detect asymptomatic malaria. Objectives. This study was done to find cases of asymptomatic malaria through the optimization of malaria diagnostic procedures at the primary health care facilities in the Batubara District, North Sumatera Province of Indonesia. Material and methods. SME was conducted for three consecutive days once a microscopic examination provided a negative result. A diagnosis of malaria is confirmed by optimization of routine microscopic examination (ORME). SME is then carried out on the 2nd day (first SME), the 8th day (second SME) and the 15th day (third SME). An examination was declared negative once Plasmodium sp. is not found up to 500 high power field. Results. SME of 1,597 patients who had negative results on the first microscopic examination revealed that 95 had submicroscopic malaria (5.9%). This study found asymptomatic malaria in 20.3% of the study subjects (188 persons) at first microscopic examination, 3.7% (34 persons) at first SME and 3% (28 persons) at second SME. Conclusions. ORME and SME performed on people at risk of malaria provide the possibility to detect asymptomatic malaria. [ABSTRACT FROM AUTHOR]

Objectives: To estimate in gynecologically asymptomatic postmenopausal women with and without hormone replacement therapy (HRT) undergoing transvaginal ultrasound examination the prevalence of: endometrial thickness ≥ 5.0 mm, intrauterine focal lesions if endometrial thickness is ≥ 5.0 mm, and premalignant and malignant endometrial changes if thickness is ≥ 5.0 mm and intrauterine focal lesions are present.Methods: Invitation letters were sent to 2951 potentially eligible women recruited from a Swedish population registry; 757 replied, 514 were considered eligible (i.e. were gynecologically asymptomatic postmenopausal women aged 52-62 years with no current or previous gynecological problems) and 510 had complete information and were included. The women were examined using transvaginal ultrasound (5-9-MHz transducer). If endometrial thickness was ≥ 5.0 mm, saline contrast sonohysterography (SCSH) was attempted. The number, size and surface contour of intracavitary focal lesions were recorded. Women with focal lesions were offered hysteroscopic resection of the lesions. Gold standard was histology of the surgical specimen.Results: The median time in menopause was 5 (range, 1-17) years. There were no substantial differences in ultrasound findings between women with HRT and those without. Sixty-two (12% (95% CI, 9-15%)) women had an endometrial thickness ≥ 5.0 mm. SCSH was attempted in 54 of these women, which was successful in 48 and suboptimal in one. Thirty-three (67%) of the 49 women with successful or suboptimal SCSH and one woman with spontaneous fluid in the uterine cavity had intracavitary focal lesions. Twenty-nine of these women with focal lesions underwent hysteroscopic resection of the lesion(s). Two cases of endometrial complex hyperplasia with atypia but no malignancy were found. Uterine perforation with bowel damage occurred in two women who underwent hysteroscopic surgery.Conclusion: About 10% of gynecologically asymptomatic postmenopausal women have a sonographic endometrial thickness ≥ 5.0 mm. Our results support conservative management of such women. Copyright © 2015 ISUOG. Published by John Wiley & Sons Ltd. [ABSTRACT FROM AUTHOR]

Objective To evaluate the clinical differences between patients with diabetes mellitus (DM) who have asymptomatic carpal tunnel syndrome (CTS) and those who have symptomatic CTS. Methods Sixty-three patients with DM were assessed using the Boston Carpal Tunnel Questionnaire (BCTQ), nerve conduction studies (NCS), and ultrasonographic evaluation of the cross-sectional area (CSA) of the median nerve. According to the BCTQ responses and NCS results, the patients were divided into the following three groups: group 1 (n=16), in which NCS results did not reveal CTS; group 2 (n=19), in which NCS results revealed CTS but the group scored 0 points on the BCTQ (asymptomatic); and group 3 (n=28), in which NCS results revealed CTS and the group scored >1 point on the BCTQ (symptomatic). The clinical findings, NCS results, and CSA of the median nerve were compared among the three groups. Results There were no significant differences in age, DM duration, glycated hemoglobin levels, and presence of diabetic polyneuropathy among the three groups. The peak latency of the median sensory nerve action potential was significantly shorter in group 1 than in groups 2 and 3 (p<0.001); however, no difference was observed between groups 2 and 3. CSA of the median nerve at the carpal tunnel in group 2 was significantly larger than that in group 1 and smaller than that in group 3 (p<0.05). Conclusion The results of our study suggest that the symptoms of CTS in patients with diabetes are related to CSA of the median nerve, which is consistent with swelling of the nerve.

To evaluate the feasibility of using coronary magnetic resonance angiography (CMRA) with stress-perfusion and delayed-enhancement MRI as a screening tool for the detection of coronary artery disease (CAD) in asymptomatic subjects. Three hundred and forty-one self-referred asymptomatic subjects were enrolled in this study. Cardiac MR imaging was performed using a 1.5-T scanner with a 32-channel cardiac coil. Coronary artery stenosis, regional wall motion abnormalities, myocardial perfusion abnormalities, and delayed myocardial enhancement were analyzed. The occurrence of new chest pain and cardiac events was assessed in 332 subjects (97.3 %) over an average 29 ± 6 months (range, 18-39 months) follow-up period. A total of 3296 (82.4 %) of 4000 coronary artery segments examined exhibited diagnostic image quality on combined whole-heart and volume-targeted CMRA. Combined MRI detected significant CADs in 13 (3.8 %) of 341 subjects. Among these, 11 subjects (84.6 %) had both coronary artery stenosis (≥50 % by diameter) on CMRA and stress-perfusion defects in corresponding areas. Five of the 13 subjects showed evidence of old myocardial infarctions on delayed-enhancement MRI. Three subjects (0.9 %) underwent percutaneous coronary intervention after CAD was detected on cardiac MRI. There were no cardiac events during the follow-up period in subjects who complied with follow-up. Normal stress-perfusion and delayed-enhancement MRI lead to excellent outcomes when used to predict future cardiac events in asymptomatic subjects. Coronary MRA correlates well with stress-perfusion MRI for detecting significant CAD and helps exclude CAD in asymptomatic individuals. [ABSTRACT FROM AUTHOR]

ABSTRACT Objectives To estimate the prevalence of extrauterine pelvic lesions on transvaginal ultrasound examination of gynecologically asymptomatic women of fertile age, and to compare this prevalence between women with spontaneous menstrual cycles, those using the combined oral contraceptive ( COC) pill and those using a gestagen intrauterine contraceptive device ( IUD). Methods Six hundred and forty-four gynecologically asymptomatic 20-39-year-old Caucasian women with no current or previous gynecological problems, who were recruited from a Swedish population registry, were examined with transvaginal ultrasound on cycle day 4-8. Our definition of ovarian cyst was a unilocular cyst with anechoic cyst contents ≥ 35 mm in mean diameter, or any other type of intraovarian lesion. The prevalence of extrauterine pelvic lesions was compared between women not using hormonal contraception and those using COC or a gestagen IUD. Results Ovarian lesions were found in 24 (3.7%) women. One woman had bilateral ovarian lesions. An ultrasound diagnosis of paraovarian cyst was made in 41 (6.4%) women, of peritoneal cyst in four (0.6%) women and of hydrosalpinx in one (0.2%) woman. All incidentally detected lesions had a mean diameter of ≤ 5 cm. One 17-mm intraovarian lesion was suspicious for malignancy, and histology confirmed a Sertoli-Leydig cell tumor. The ultrasound diagnoses in the remaining 23 women were endometrioma ( n = 10 (1.6%)), dermoid cyst ( n = 5 (0.8%)), cystadenofibroma ( n = 1 (0.2%)), mature teratoma ( n = 1 (0.2%)) and functional cyst, i.e. a cyst that resolved within 3-5 months ( n = 6 (0.9%)). Four women with an ultrasound diagnosis of a benign lesion were operated on, and the ultrasound diagnoses of endometrioma ( n = 2), dermoid cyst ( n = 1) and mature teratoma ( n = 1) were confirmed histologically. The prevalence of persisting ovarian lesions was highest in women with spontaneous menstrual cycles (4.4% vs 0.9% and 0% in women using COC and gestagen IUD, respectively; P = 0.025), but age was the only factor independently associated with persisting ovarian masses, the prevalence increasing with age. Conclusions Benign ovarian lesions are found in about 1 in 25 gynecologically asymptomatic women aged 20-39 years with no history of gynecological disease. To be able to offer optimal management of such masses, their natural history needs to be elucidated in a large prospective observational study. Copyright © 2013 ISUOG.

We aimed to investigate the prevalence and severity of noncalcified coronary plaques (NCP) using coronary CT angiography (CCTA) and analyze predictors of significant coronary stenosis by NCP in asymptomatic subjects with low coronary artery calcium score (CACS). The institutional review board approved this retrospective study and all patients gave written, informed consent. The presence of plaque, severity of stenosis, plaque characteristics, and CACS were assessed in 7,515 asymptomatic subjects. We evaluated the prevalence and severity of NCP in subjects having low CACS (707 subjects; men with CACS from 1 to 50 and women from 1 to 10) in comparison to those having 0 CACS (6,040 subjects) as the reference standard. Conventional risk factors were assessed for predictors of NCP and significant stenosis by NCP. We also investigated the cardiac events of the patients through medical records. Compared to subjects with 0 CACS, those with low CACS showed higher prevalence of NCP (6.9% vs. 31.5%, P < 0.001) and significant stenosis caused by NCP (0.8% vs. 7.5%, P < 0.001). In the low CACS group, independent predictors for significant NCP included diabetes mellitus (DM), hypertension, and elevated low-density lipoprotein (LDL)-cholesterol (all P < 0.05). However, 47.2% of subjects with significant NCP were classified into the low to intermediate risk according to Framingham Risk Score. At the median follow up of 42 months (range: 3-60 months), cardiac events were significantly higher in the low CACS group compared to the 0 CACS group (2.6% vs. 0.27%, P < 0.001). In asymptomatic subjects having low CACS, the prevalence and severity of NCP were higher as compared to subjects having zero CACS and predictors of significant stenosis by NCP were DM, hypertension and LDL-Cholesterol. Therefore, CCTA may be useful for risk stratification of coronary artery disease as added value over CACS in selected populations with low CACS who have predictors of significant NCP.

Cervical lymphadenopathy is a common presentation of nasopharyngeal carcinoma (NPC). It can be present in the classical location of the level II or VI lymph nodes or at any other levels of the lymph nodes in the neck. NPC should be suspected when a patient presents with cervical lymphadenopathy and conductive hearing loss. A thorough endoscopic assessment of the nasopharynx should be performed to rule out this radiotherapy-curable disease at its early stage. [ABSTRACT FROM AUTHOR]

Acute appendicitis is one of the most common abdominal emergencies, even though most cases of appendicitis will be due to obstruction of the appendiceal lumen, in rare occasions and mostly due to poor sanitary conditions a parasitic infection may cause appendicitis. Entamoeba histolytica is a common parasite and has a broad clinical spectrum from an asymptomatic disease to a life-threatening condition. In rare occasions, trophozoites can invade the appendiceal wall causing appendicitis. Preoperative diagnosis of acute amebic appendicitis is usually difficult, yet surgical treatment as in non-amebic appendicitis is the treatment of choice. However, due to the increased rate of postoperative complications associated with acute amebic appendicitis, a course of nitroimidazoles, and increased awareness in basic sanitary measures is usually recommended. We present a case of a 29-year-old woman, she presented with abdominal pain and appendicitis was suspected. After successful surgery, pathology confirmed acute amebic appendicitis.
