RESUMEN
A patient with a swelling of the abdominal wall is a regular occurrence in general practice and hospital. The diagnosis can often be made with a thorough history and physical examination. An abdominal wall hernia is characterized by an increase in swelling on standing physical examination and Valsalva maneuver, which is often reducible, and a hernia defect is palpable. If no interruption of the abdominal wall is palpable and there is hypoesthesia, there may be an abdominal wall paresis because of thoracic paramedian hernia nuclei pulposi (HNP). Where an abdominal wall hernia is treated surgically in case of symptoms, this is conservatively treated with an HNP.

Chronic diarrhea in children is challenging both with regards to etiological diagnosis and for management. Etiology and pathophysiological mechanisms vary widely from neonates to adolescents. Congenital or genetic causes are more frequent in neonates, while infections, allergy and immune-mediated mechanisms are more frequent in childhood. A thorough history and proper physical examination are required to decide for further diagnostic evaluation. The approach to a child with chronic diarrhea should be age specific and based predominantly on the pathophysiological mechanism involved. The nature of the stool like watery, bloody or fatty (steatorrhea) can suggest the probable etiology and organ system involved. After routine tests, evaluation with specific serological tests, imaging, endoscopy (gastroscopy/colonoscopy), histopathology of intestinal mucosa, breath tests or radionuclide imaging may be required to make a definitive diagnosis. Genetic evaluation is important in congenital diarrheas, monogenic inflammatory bowel disease (IBD) and immunodeficiency disorders. Management is aimed at stabilization, nutritional support and etiology specific treatment. Specific therapy can be as simple as exclusion of specific nutrient or as complicated as small bowel transplant. Evaluation and management require expertise and thus patients need to be referred in a timely fashion. This will minimise morbidity including nutritional consequences and improve outcome.

Common disorders of the gastrointestinal (GI) tract, such as gastroesophageal reflux/disease (GER/D) and constipation, are frequent causes for seeking medical support in infants. Diagnostic workup must ensure that diagnosed diseases are responsible for such complaints, thus enabling appropriate therapy. In this context assessment consists of clinical examination, functional tests, and imaging, which should be done in a staged manner. Close cooperation between clinicians and clinical radiologists enables optimal diagnostics, thus forming the basis for appropriate therapy.

Sudden cardiac death is defined as an abrupt, unexpected death of cardiovascular cause with loss of consciousness within 1 hour of onset of symptoms. In an effort to prevent these events, clinicians need to recognize symptoms to identify at risk patients. There is often an overlap in symptoms of chest pain, palpitations, and syncope. The workup depends on the characteristics of these symptoms. The history and physical examination often provide adequate information, but additional testing and referral to pediatric cardiology are sometimes indicated.

Retinal vascular occlusion (RVO) are common causes of visual impairment. Accurate recognition and differential diagnosis of RVO are unmet medical needs for determining appropriate treatments and health care to properly manage the ocular condition and minimize the damaging effects. To leverage deep learning as a potential solution to detect RVO reliably, we developed a deep learning model on color fundus photographs (CFPs) using a two-step masked SwinTransformer with a Few-Sample Generator (FSG)-auxiliary training framework (called DeepDrRVO) for early and differential RVO diagnosis. The DeepDrRVO was trained on the training set from the in-house cohort and achieved consistently high performance in early recognition and differential diagnosis of RVO in the validation set from the in-house cohort with an accuracy of 86.3%, and other three independent multi-center cohorts with the accuracy of 92.6%, 90.8%, and 100%. Further comparative analysis showed that the proposed DeepDrRVO outperforms conventional state-of-the-art classification models, such as ResNet18, ResNet50d, MobileNetv3, and EfficientNetb1. These results highlight the potential benefits of the deep learning model in automatic early RVO detection and differential diagnosis for improving clinical outcomes and providing insights into diagnosing other ocular diseases with a few-shot learning challenge. The DeepDrRVO is publicly available on https://github.com/ZhouSunLab-Workshops/DeepDrRVO.

OBJECTIVES: Occupational exposure to vibration using hand-held tools may cause hand-arm vibration syndrome (HAVS). Correct diagnosis and grading of severity are crucial in protecting the individual's health and for workers' compensation claims. The International Consensus Criteria (ICC) has been suggested to replace the widely used Stockholm Workshop Scale (SWS). The aims were to, in a clinical setting, assess the concordance between the SWS and the ICC neurosensory severity grading of vibration injury, and to present the clinical picture according to symptoms, type of affected nerve fibres and the relation between vascular and neurosensory manifestations. METHODS: Data were collected from questionnaires, clinical examination and exposure assessment of 92 patients with HAVS. The severity of neurosensory manifestations was classified according to both scales. The prevalence of symptoms and findings was compared across groups of patients with increasing severity according to the SWS. RESULTS: Classification with the ICC resulted in a shift towards lower grades of severity than with the SWS due to a systematic difference between the scales. Affected sensory units with small nerve fibres were far more prevalent than affected units with large nerve fibres. The most prevalent symptoms were numbness (91%) and cold intolerance (86%). CONCLUSIONS: Using the ICC resulted in lower grades of the severity of HAVS. This should be taken into consideration when giving medical advice and approving workers' compensation. Clinical examinations should be performed to detect affected sensory units with both small and large nerve fibres and more attention should be paid to cold intolerance.

BACKGROUND: Orbital cellulitis is a potentially life-threatening condition. Compression of the optical nerve can cause total or partial loss of vision. Early diagnosis is crucial to prevent complications. In case of a unilateral sinusitis as cause of a unilateral orbital cellulitis complete clinical and dental examination combined with imaging are essential in diagnostics. CASE DESCRIPTION: A 53-year-old man presented with left eye movement impairment, intermittent diplopia and moderate swelling of the left lower eyelid. His diagnosis was post septal orbital cellulitis and despite administration of oral antibiotics no clinical improvement was observed. Orbital imaging by CT could not exclude a dental cause of his unilateral maxillary sinusitis. He was referred to the department of oral and maxillofacial surgery where clinical examination showed a dental cause. After removal of two decayed upper molars a complete recovery was accomplished. CONCLUSION: Odontogenic causes for unilateral orbital cellulitis should always be considered in diagnostics in adults. Clinical presentation and dental examination combined with adequate imaging can confirm the diagnosis.

Importance: Skin cancer is the most common cancer type and is a major cause of morbidity. Objective: To systematically review the benefits and harms of screening for skin cancer to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials from June 1, 2015, through January 7, 2022; surveillance through December 16, 2022. Study Selection: English-language studies conducted in asymptomatic populations 15 years or older. Data Extraction and Synthesis: Two reviewers independently appraised the articles and extracted relevant data from fair- or good-quality studies; results were narratively summarized. Main Outcomes and Measures: Morbidity; mortality; skin cancer stage, precursor lesions, or lesion thickness at detection; harms of screening. Results: Twenty studies in 29 articles were included (N = 6â¯053â¯411). Direct evidence on screening effectiveness was from 3 nonrandomized analyses of 2 population-based skin cancer screening programs in Germany (n = 1â¯791â¯615) and suggested no melanoma mortality benefit at the population level over 4 to 10 years' follow-up. Six studies (n = 2â¯935â¯513) provided inconsistent evidence on the association between clinician skin examination and lesion thickness or stage at diagnosis. Compared with usual care, routine clinician skin examination was not associated with increased detection of skin cancer or precursor lesions (5 studies) or stage at melanoma detection (3 studies). Evidence on the association between clinician skin examination and lesion thickness at detection was inconsistent (3 studies). Nine studies (n = 1â¯326â¯051) found a consistent positive association between more advanced stage at melanoma detection and increasing risk of melanoma-associated and all-cause mortality. Two studies (n = 232) found little to no persistent cosmetic or psychosocial harms associated with screening. Conclusions and Relevance: A substantial nonrandomized evidence base suggests a clear association between earlier stage at skin cancer detection and decreased mortality risk. However, nonrandomized studies suggest little to no melanoma mortality benefit associated with skin cancer screening with visual skin examination in adolescents or adults and no association between routine clinician skin examination and earlier stage at melanoma detection. Evidence is inconsistent regarding whether clinician skin examination is associated with thinner melanoma lesions at detection.

Importance: Skin cancer is the most commonly diagnosed cancer in the US. There are different types of skin cancer varying in disease incidence and severity. Basal and squamous cell carcinomas are the most common types of skin cancer but infrequently lead to death or substantial morbidity. Melanomas represent about 1% of skin cancer and cause the most skin cancer deaths. Melanoma is about 30 times more common in White persons than in Black persons. However, persons with darker skin color are often diagnosed at later stages, when skin cancer is more difficult to treat. Objective: To update its 2016 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on the benefits and harms of screening for skin cancer in asymptomatic adolescents and adults. Population: Asymptomatic adolescents and adults who do not have a history of premalignant or malignant skin lesions. Evidence Assessment: The USPSTF concludes that the evidence is insufficient to determine the balance of benefits and harms of visual skin examination by a clinician to screen for skin cancer in asymptomatic adolescents and adults. Recommendation: The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of visual skin examination by a clinician to screen for skin cancer in adolescents and adults.

Purpose: Dry eye disease (DED) is because of a decrease in the tear film's volume or a change in the composition of tears. Evaporative dry eye is the most common type, which is due to meibomian gland dysfunction (MGD). In this study, the morphology of meibomian glands was evaluated in all kinds of dry eyes to look for any loss of meibomian glands, assess the function of remaining glands, and investigate the relationship between anatomy, function, and severity of DED. Methods: A total of 300 patients were included in the study, with 150 eyes in the study group and 150 in the control group. Meibomian gland morphology was assessed by examining the tarsal plate after everting the eyelids. Tear film function was evaluated using tear film break-up time (TBUT) and Schirmer's test (SCH I and II). Meibomian gland morphology was examined with a slit-lamp under magnification, a transilluminator using a small light emitting diode (LED) bulb, and non-contact meibography using an auto refracto-keratometer (ARK). Results: Females had a higher prevalence of dry eyes in our study. In all, 103 eyes (68.6%) in the study group had evaporative dry eye, making it the most prevalent type. Among the 150 controls, 104 controls with 69.3% had no dry eye symptoms, and in those with symptoms, the evaporative type was the most common, with a 28% prevalence. Conclusion: TBUT should be performed in all patients with detectable MG abnormality. Meibography has high specificity and sensitivity to diagnose MGD and in turn dry eyes and should be considered a routine screening modality.

Axial neck pain is a common and important problem in the outpatient setting. In isolation, neck pain tends to have a musculoskeletal etiology and responds best to medication and targeted physical therapy. Careful history and physical examination are required to ascertain if there is a neurologic component in addition to the patient's neck pain. For patients needing surgical intervention, there are a variety of approaches and operations that can decompress the appropriate nerve root or the spinal cord itself. These operations are generally well-tolerated and provide significant benefit for appropriately selected patients.

Edema of the lower extremities is always associated with a pathological condition that should be treated, especially in patients with chronic wounds. Because the underlying causes of edema can vary greatly and sometimes be complex, clinical and, if necessary, various diagnostic tests should also be performed. Often, a suspected clinical diagnosis can already be made after clinical inspection with testing of Stemmer's and Godet's signs. Sonographic examination should then be performed as the next diagnostic test. Although measurement techniques such as water plethysmography are currently considered gold standard for volume measurements, they are very complex and prone to error, so that they are rarely used in clinical routine today. In summary, it is recommended to perform a clinical examination, if possible in combination with sonography, for edema diagnosis. Especially at the beginning of the decongestion phase, regular circumferential measurements should be performed and documented. This documentation is of high relevance for evaluation of therapeutic success.

The majority of patients with acute back pain have no serious underlying disease; however, many internal diseases can be manifested as acute or chronic back pain. Therefore, in the assessment of patients with back pain the clinical history and clinical examination are important in order to detect indications for a possible underlying disease. Particularly red flags that indicate an acute or life-threatening disease should not be missed. In most cases where such red flags, risk factors or clinical indications are not present, no systematic search for internal underlying diseases is necessary. This article summarizes the most relevant differential diagnoses and clinical indications as well as warning symptoms.

PURPOSE: Epistaxis is a common symptom and can be caused by various diseases, including nasal diseases, systemic diseases, etc. Many misdiagnosis and missed diagnosis of epistaxis are caused by lack of clinical knowledge and experience, especially some interns and the clinicans in primary hospitals. To help inexperienced clinicans improve their diagnostic accuracies of epistaxis, a computer-aided diagnostic system based on Dynamic Uncertain Causality Graph (DUCG) was designed in this study. METHODS: We build a visual epistaxis knowledge base based on medical experts' knowledge and experience. The knowledge base intuitively expresses the causal relationship among diseases, risk factors, symptoms, signs, laboratory checks, and image examinations. The DUCG inference algorithm well addresses the patients' clinical information with the knowledge base to deduce the currently suspected diseases and calculate the probability of each suspected disease. RESULT: The model can differentially diagnose 24 diseases with epistaxis as the chief complaint. A third-party verification was performed, and the total diagnostic precision was 97.81%. In addition, the DUCG-based diagnostic model was applied in Jiaozhou city and Zhongxian county, China, covering hundreds of primary hospitals and clinics. So far, the clinicians using the model have all agreed with the diagnostic results. The 432 real-world application cases show that this model is good for the differential diagnoses of epistaxis. CONCLUSION: The results show that the DUCG-based epistaxis diagnosis model has high diagnostic accuracy. It can assist primary clinicians in completing the differential diagnosis of epistaxis and can be accepted by clinicians.

INTRODUCTION: Lipoma of the nerve is an uncommon tumor, and usually has the highest incidence in the upper limb, especially in the median nerve. When the lesion is large it can cause peripheral neuropathy such as carpal tunnel syndrome. Therefore, a physical examination is paramount for correct surgery and patient preparation. In this article we present a case that was mainly diagnosed by a complete physical examination, which led to the selection of appropriate surgery for the patient.

PURPOSE: To examine the relationship between contact lens (CL) discomfort and meibomian gland (MG) morphology assessed by a semi-objective software in subjects without an alteration of MG function (meibum quality and expressibility). METHODS: Nineteen symptomatic (CLDEQ-8â¯≥â¯12) CL wearers, 19 asymptomatic (CLDEQ-8â¯<â¯12) wearers, and 22 non-wearers were recruited. Upper and lower eyelid meibography images were taken and the following parameters were analysed using a semi-objective software in the central 2/3 of each eyelid: number of MG, number of partial MG, percentage of MG loss and percentage of tortuosity. One-way ANOVA or Kruskal-Wallis H test were used for comparisons among groups. The relationships between CLDEQ-8 and MG morphology parameters were analysed using the Spearman correlation coefficient and multivariable linear regression models. RESULTS: No significant differences were found among groups in the MG morphology of the upper or lower eyelids. In all CL wearers, a significant correlation with CLDEQ-8 was found in the upper eyelid for the number of MG (rhoâ¯=â¯0.47, pâ¯=â¯0.003). In symptomatic wearers, significant correlations with CLDEQ-8 were found in the lower eyelid for the number of partial MG (rhoâ¯=â¯0.49, pâ¯=â¯0.03) and the percentage of partial MG (rhoâ¯=â¯0.61, pâ¯=â¯0.005). In all CL wearers, multivariable models were fitted to explain CLDEQ-8 score including the number of MG, the number of partial MG and the percentage of MG loss from the lower eyelid (R2â¯=â¯0.19; pâ¯=â¯0.007), and the number of MG from the upper eyelid (R2â¯=â¯0.19; pâ¯=â¯0.001). In symptomatic wearers, a model was fitted including the percentage of MG loss from the lower eyelid (R2â¯=â¯0.30; pâ¯=â¯0.016). CONCLUSIONS: Alterations of MG morphology, without clinically apparent alteration of MG function, can be involved in causing CL discomfort and influence the degree of symptoms. The differences in findings between eyelids indicate the need to monitor both eyelids, especially the lower one, in CL wearers.

When treating marine rashes, it is imperative to properly diagnose the root cause to guide appropriate treatment. Two of the most common rashes experienced after ocean contact are known colloquially as seabather's eruption and diver's dermatitis. In many cases, a thorough history and physical examination can aid in elucidating the responsible organism. Understanding the etiology of rashes obtained in marine environments can improve patient education on precautionary measures that can be taken to avoid exposure. Reasons for further research in this area include development of more effective treatments, as current therapies are limited to symptom management.

One of the most common causes of radiculopathy requiring neurosurgical treatment is a herniated disc. Magnetic resonance imaging (MRI) is still the main diagnostic approach for this lesion. However, MRI does not allow assessing the functional state of the root. Neurophysiological examination assesses the function of peripheral nervous system. These methods are used for differential diagnosis of causes of neurological symptoms and determine the level of the nerve root injury. OBJECTIVE: To assess the role of electromyography including paraspinal muscle mapping in diagnosis of radiculopathies following spine diseases. MATERIAL AND METHODS: We have analyzed literature data in the Scopus, Pubmed, and RSCI databases and selected 93 references for primary reviewing. Final analysis enrolled the manuscripts with a detailed description of neurophysiological examinations and data on sensitivity/specificity of these methods. RESULTS: Needle electromyography (EMG) is the most informative neurophysiological method for diagnosis of radicular damage. Sensitivity of EMG is up to 90% for lumbosacral radiculopathy. Electromyography of the paraspinal muscles can be used in case of of cervical, thoracic and lumbar radiculopathy in addition to EMG of limb muscles. Therefore sensitivity increases to 100%. Diagnostic value of nerve conduction study (NCS) is low, and performing NCS without EMG is not useful. CONCLUSION: In neurosurgical practice electrodiagnostic (EDX) should be performed for differential diagnosis of radiculopathy and peripheral nervous system lesions, to determine the level of radicular compression, and when physical examination does not correspond with neuroimaging or MRI is not possible to perform.

Headache is a common symptom in pregnancy. The differential diagnosis for headache in pregnancy is broad and includes conditions that range in acuity and severity. Most headaches in pregnancy are migraine or tension-type headaches. However, pregnant women are at an increased risk of vascular causes of headache due to hormone changes and increased hypercoagulability in pregnancy. A careful history, physical examination, and possible diagnostic workup should be performed. Treatment of headache in pregnancy varies according to the etiology, but care should be taken when performing diagnostic studies and considering pharmacologic treatments, given the possible risk to the mother and fetus.
