OBJECTIVETo explore the influence of fiberform on the defecation condition after surgery for benign anorectal lesion.

METHODSA total of 121 cases undergoing surgery for benign anorectal lesion at the Third Affiliated Hospital of Nanjing University of Traditional Chinese Medicine from October 2009 to February 2010 were randomly divided into the treatment group (n=61) and the control group (n=60) according to random number table. Patients in the treatment group received fiberform granule for 2 weeks while patients in the control group did not receive any medication to promote defecation. Postoperative defecation symptom scores and patient satisfaction were compared between the two groups.

RESULTSOn postoperative day 7, patients in the treatment group had a lower defecation smoothness score (62.1% decrease), lower fecal character score (74.3% decrease), lower defecation interval score (80.2% decrease), lower defecation pain score (77.5% decrease), the differences were statistically significant. On postoperative day 14, the degree of decrease of the abovementioned score were 58.3%, 88.5%, 82.8% and 83.1%, respectively. Postoperative patient satisfaction rate in the treatment group was significantly higher than that in the control group(P<0.05). No patient in the treatment group experienced any adverse events such as abdominal pain, diarrhea, and drug dependence.

CONCLUSIONFiberform can effectively prevent defecation disorders such as dry stool, unsmooth defecation, and anorectal pain.

OBJECTIVETo analyze the clinical features and diagnostic points of occupational acute dimethylformamide (DMF) poisoning and to explore the mechanism of occupational acute DMF poisoning.

METHODSA comprehensive analysis was performed on the clinical data of 16 cases of occupational acute DMF poisoning, including symptoms, signs, and laboratory testing results.

RESULTSThe main clinical features of occupational acute DMF poisoning were digestive system impairments, especially abdominalgia. Hemorrhagic gastroenteritis was not found by gastroscopy. There was no significant correlation between the degree of abdominalgia and alanine aminotransferase level (r(s) = 0.109, P>0.05).

CONCLUSIONAbdominalgia is recommended to be one of the reference indices for the diagnosis and degrading of occupational acute DMF poisoning, The mechanism of DMF poisoning remains unclear but it is considered to be related to methyl isocyanate, the intermediate product of DMF metabolism.

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) is closely related with a wide range of gastrointestinal disease. One-week triple therapy is currently considered as the golden standard for the treatment of H. pylori infection. However, gastrointestinal abnormal responses are major pitfalls in such regimen. The aim of this study was to identify symptoms, frequency and severity of antibiotics-associated gastrointestinal abnormal responses during H. pylori eradication therapy. METHODS: Sixty-seven patients with H. pylori infection between September 2005 and March 2006 were included. After 1 week of H. pylori eradication triple therapy (rabeprazol 10 mg, clarithromycin 500 mg, amoxicillin 1 g bid), we evaluated gastrointestinal abnormal responses (diarrhea, bloating, constipation, abdominal pain, borborygmus, flatulence, stool frequency, belching, and nausea) and severities every week for 4 weeks. RESULTS: The incidence of diarrhea was the highest in week 1, which was 41.28% (n=28) and the lowest in week 4, which was 9.52% (n=6) and decreased from week 1 to week 4 with statistical significance (p<0.0001). The most common gastrointestinal abnormal responses were associated with flatulence in week 1 (n=21, 31.34%), week 2 (n=21, 33.33%) and abdominal distention in week 3 (n=16, 25.40%), week 4 (n=15, 23.81%). Most of gastrointestinal abnormal responses were mild, and the most common symptom with higher than moderate grade was abdominal pain (n=4, 40.00%) in week 1. Alcohol consumption and coexisting medical illness were not associated with diarrhea (p=0.0852, 0.9009 respectively). CONCLUSIONS: H. pylori eradication therapy is commonly associated with antibiotics-associated gastrointestinal abnormal responses, which may result in antibiotics intolerance and H. pylori eradication failure. Even though those symptoms are not so severe, we have to consider the gastrointestinal abnormal responses associated with H. pylori eradication, especially diarrhea.

Methimazole (MMI)-induced acute pancreatitis is very rare but severe adverse reaction. A 51-yr-old male developed a high fever, chills, and abdominal pain, two weeks after commencement on MMI for the treatment of Graves' disease. There was no evidence of agranulocytosis, and fever subsided soon after stopping MMI treatment. However, 5 hr after taking an additional dose of MMI, abdominal pain and fever developed again. His symptoms, biochemical, and imaging studies were compatible with acute pancreatitis. After withdrawal of MMI, he showed clinical improvement. This is the first case of MMI-induced acute pancreatitis in Korea. Clinicians should be aware of the rare but possible MMI-induced pancreatitis in patients complaining of fever and abdominal pain.

Objective: To investigate the clinical characteristics and related factors of corticosteroid induced adrenal crisis (AC) in children with primary nephrotic syndrome (NS). Methods: Case control study. The case group included 7 children aged 1 to 18 years with NS combined with AC hospitalized in Peking University First Hospital from January 2016 to May 2021 (AC group). According to the ratio of case group: control group 1: 4, 28 children aged 1 to 18 years who were diagnosed with NS without AC during the same period were matched as controls (non-AC group). Clinical data were collected. The clinical characteristics of AC were described. The clinical parameters were compared between the 2 groups by t test, Mann-Whitney U test or Fisher's test. Receiver operating characteristic (ROC) curve was used to analyze the cutoff values of clinical parameters for prediction of AC. Results: The AC group included 4 boys and 3 girls aged 6.9 (4.6, 10.8) years. The non-AC group included 20 boys and 8 girls aged 5.2 (3.3, 8.4) years. All AC events occurred during the relapse of NS with infection. Seven children had gastrointestinal symptoms such as nausea, vomiting and abdominal pain. Six children had poor mental state or impaired consciousness. No significant differences in NS course, corticosteroid treatment course, corticosteroid type, steroid dosage, steroid medication interval, the proportion of gastroenteritis and fever existed between the two groups (all P>0.05). Compared with the non-AC group, the duration from the onset of the relapse of NS until hospitalization in the AC group was significantly shorter (0.2 (0.1, 0.6) vs. 1.0 (0.4, 5.0) month,U=25.50, P=0.005). The 24 h urinary total protein (UTP) level was significantly higher in the AC group (193 (135, 429) vs. 81 (17, 200) mg/kg, U=27.00,P=0.036) than the non-AC group. The serum albumin level in the AC group was significantly lower((13.1±2.1) vs. (24.5±8.7) g/L,t=-6.22,P<0.001) than the non-AC group. There were significantly higher total white blood cell counts ((26±9)×10⁹ vs. (11±5)×10⁹/L,t=4.26,P=0.004), percentage of neutrophils (0.71±0.08 vs. 0.60±0.19,t=2.56,P=0.017) and the proportion of children with C reactive protein level≥8 mg/L (3/7 vs. 0,P=0.005) in the AC group than in the non-AC group. ROC curve analysis showed that the cutoff value of 24 h UTP was 122 mg/(kg·d) with a sensitivity of 100.0% and specificity of 70.4%. The cutoff value of serum albumin was 17.0 g/L with a sensitivity of 100.0% and specificity of 82.1%. Conclusions: Gastrointestinal symptoms and poor mental state were prominent manifestations of AC in children with NS. High 24 h UTP level, low serum albumin level, high peripheral white blood cell counts, high neutrophils percentage, and high C-reactive protein level during the early stage of NS relapse may be related to the occurrence of AC in children with NS.

BACKGROUND/AIMS: This integrated analysis aimed to identify the factors associated with the most frequently reported treatment-emergent adverse events (TEAEs) in Asian and non-Asian patients with chronic constipation (CC) who receive prucalopride or placebo over 12 weeks. METHODS: Pooled data from four randomized, double-blind, placebo-controlled, multicenter, phase III studies (NCT00488137, NCT00483886, NCT00485940, and NCT01116206) on patients treated with prucalopride 2 mg or placebo were analyzed. The associations between predictors and TEAEs were evaluated based on a logistic regression model. RESULTS: Overall, 1,821 patients (Asian, 26.1%; non-Asian, 73.9%) were analyzed. Prucalopride treatment was significantly associated with diarrhea, headache, and nausea (p<0.001), but not with abdominal pain, compared with placebo. Differences in the prevalence of TEAEs between prucalopride and placebo decreased greatly after the first day of treatment. Compared with non-Asians, Asians were more likely to experience diarrhea and less likely to develop abdominal pain, headache, and nausea. Prior laxative use, CC duration, and body weight were not predictive of any of these TEAEs. CONCLUSIONS: Prucalopride treatment was positively associated with diarrhea, headache, and nausea. Asian patients tended to have a higher frequency of diarrhea but lower frequencies of headache, abdominal pain, and nausea compared with non-Asians.

Hydrogen peroxide is commonly used as a disinfectant that has been reported to cause chemical colitis. We report a case of 49 year-old man who presented with chemical colitis caused by self-inflicted hydrogen peroxide enema. In the sigmoidoscopic examination, diffuse erythematous and edematous mucosal change with multiple ulcerations and easy touch bleeding was noted from the rectum to the proximal sigmoid colon. Abdominal computed tomography showed diffuse wall thickening of the rectum and the sigmoid colon with inflammatory and reactive change at surrounding. The patient was treated with NPO, intravenous fluid, and antibiotic therapy. On 5th hospital day, abdominal pain and bloody stool disappeared, and the patient started oral feeding. He discharged on 6th hospital day with fully recovered state.

OBJECTIVETo evaluate the safety of recombinant human interferon alpha-2b for nasal spray for the prevention of SARS and other upper respiratory viral infections.

METHODSField epidemiologic evaluation was conducted, the design was randomized and had a synchronously parallel control group. In the study, the drugs were given for five days and all subjects were followed up for ten days.

RESULTSDuring the period of using interferon, body temperature of the experimental group was normal compared to the control group. Experimental group had more influenza-like symptoms than the control group (P < 0.05), such as headache (4.83%-7.09%), dizziness (7.17%-11.63%), lassitude (8.55%-15.06%), muscular soreness (4.43%-7.09%), pharynx dryness (12.10%-17.85%), angina (6.25%-8.72%), abdominal pain (2.30%-5.50%) and diarrhea (2.45%-5.66%). Most of side effects reached their peak with in the first 3 days. Except for pharynx dryness, the incidences of all other side effects declined after completion of the use of the trial drug, and incidences of some symptoms in experimental group were lower than those of the control group. There were no significant differences in the symptoms of cough and expectoration between the experimental group and the control group. The incidence of exanthem in the control group was significantly higher than that in the experimental group. The side effect of bloody nasal mucus was not observed in experimental group, which had been reported by other authors in several volunteer studies.

CONCLUSIONUsing recombinant human interferon alpha-2b for nasal spray could lead to some influenza-like symptoms, however, all those symptoms were mild , reversible, and relieved after completion of the use of the trial drug. No serious side effects were found during the period of following up. The authors conclude that the drug is safe.
