The Diagnostic Value of Carnett's Test with Chronic Abdominal Pain: A Narrative Review.

PURPOSE OF REVIEW: Chronic abdominal wall pain is a poorly recognized cause of chronic abdominal pain, and patients frequently go misdiagnosed despite a battery of medical tests. The Carnett's test is a diagnostic tool used to distinguish between abdominal wall pain and visceral pain. This review synthesizes the current literature on the Carnett's test, merges the viewpoints of diverse writers, and evaluates and reports on the Carnett's test's applicability. RECENT FINDINGS: Several clinical investigations have established the usefulness of the Carnett's test in the diagnosis of chronic abdominal wall pain. Furthermore, the Carnett's test is quite useful in determining the depth of the mass and detecting psychogenic abdominal pain. However, its diagnostic use for acute abdominal pain is limited. The Carnett's test is a simple and safe point-of-care diagnostic technique, with several studies supporting its usefulness. Early detection of abdominal wall pain is critical for chronic abdominal wall pain therapy. Carnett's test is very useful in patients with chronic, unexplained local abdominal discomfort who are compliant and do not have a clear rationale for surgery.

[Study on risk factors and behavior features related to chronic diseases among adults in Shanghai].

OBJECTIVE: To investigate the risk factors and behavior features related to chronic diseases among adults in Shanghai. METHODS: A total of 15 516 subjects aged over 18 years old were selected from the investigation project on chronic diseases and relevant risk factors in Shanghai in 2010. Questionnaire were used to investigate the general information of the subjects, such as behavior features as smoking, drinking, diet, physical activity as well as the prevalence and control of chronic diseases as hypertension and diabetes. The physical examination included height, weight, waist circumference, blood pressure, blood glucose and blood lipids. RESULTS: Being preprocessed by complex weighting method, the data showed that the overweight rate of Shanghai adults aged above 18 was 32.4% (5288), separately 32.2% (2506) and 32.5% (2782) (χ(2) = 0.10, P = 0.844) in urban and rural areas; the obesity rate was 8.8% (1538), separately 8.7% (738) and 8.8% (800) (χ(2) = 0.06, P = 0.901) in urban and rural areas. The overweight rate was separately 36.0% (2888) in males and 28.6% (2400) in females (χ(2) = 96.61, P < 0.01); while the obesity rate was separately 8.7% (745) in males and 8.9% (793) in females (χ(2) = 0.06, P = 0.851). Abdominal obesity rate was 44.3% (7419), separately 47.8% (3892) in males and 40.6% (3527) in females (χ(2) = 81.23, P < 0.01), 46.5% (3703) in urban areas and 42.6% (3716) in rural areas (χ(2) = 24.37, P = 0.069). Current smoking rate was 25.0% (3813), separately 48.4% (3722) and 1.2% (91) in males and females (χ(2) = 4572.06, P < 0.01); 23.6% (1609) and 26.0% (2204) in urban and rural areas (χ(2) = 11.92, P = 0.018). The regular smoking rate was 22.1% (3402). The rate of having the habit of drinking at least once a month in males was 39.5% (3102), separately 35.1% (1262) and 42.7% (1840) in urban and rural areas (χ(2) = 45.98, P = 0.012). The rate of drinking almost every day was 16.3% (1380), and the percentage of excessive alcohol consumption was 28.9% (2483). The percentage in group of subjects aging between 45-59 years old was 38.5% (1191), which was higher than that in any other groups (22.8% (641) in group aging 18-44 years old and 22.9% (651) in group aging ≥ 60 years old) (χ(2) = 241.38, P < 0.01). The percentage of over-drinking in rural area was higher than that in urban area, which was 33.5% (1578) and 22.8% (905) respectively (χ(2) = 117.12, P < 0.01). The percentage of once over-drinking was 11.3% (903). It was higher in group aging between 45-49 years old (15.3% (461)) than in other groups (9.0% (222) in group aging 18-44 years old and 8.2% (220) in group aging ≥ 60 years old) (χ(2) = 78.21, P < 0.01). It was also higher in rural area (13.5% (605)) than in urban area (8.3% (298)) (χ(2) = 51.74, P < 0.01). There were 75.0% (11 993) of the Shanghai adults never took physical activity. And the most important problems in dietary habit were insufficient intake of dairy products (98.0%, 15 218), vegetables (53.0%, 7864) and fruits (84.6%, 13 372), excess consumption of sodium (52.0%, 8257) and oil (51.7%, 7884). CONCLUSION: The risk factors of chronic diseases were highly prevalent in Shanghai. The prevalence of risk factors as overweight or obesity, lack of physical activity, smoking, over-drinking and unhealthy dietary habits were higher among adults living in suburban areas than those living in urban areas; the prevalence was also higher among the young adults than that among the elderly people, higher among males than that among females.
