Clinical characteristics of bacteremic urinary tract infection due to third-generation cephalosporin-resistant Escherichia coli in children.

Clinical characteristics of bacteremic urinary tract infection due to third-generation cephalosporin-resistant Escherichia coli in children remain unclear. We conducted a case control study comparing the clinical information of the third-generation cephalosporin-susceptible group (S-E. coli group) and the third-generation cephalosporin-resistant group (R-E. coli group). The R-E. coli group included extended-spectrum beta-lactamases (ESBLs) or AmpC-producing E. coli. We identified 52 cases of bacteremic UTI due to E. coli; 42 cases were in the S-E. coli group and 10 cases were in the R-E. coli group. Empiric antibiotics were more likely to be inappropriate for pediatric patients with bacteremic urinary tract infection due to third-generation cephalosporin-resistant E. coli than those infected by susceptible E. coli (60% vs. 0%, P < 0.001). However, duration of fever and rate of relapse were not significantly different. The outcomes of bacteremic UTI due to multidrug-resistant E. coli in children were satisfactory regardless of susceptibility to empiric antibiotics.

Effect of a Novel, Energy-Dense, Low-Volume Nutritional Food in the Treatment of Superior Mesenteric Artery Syndrome.

Superior mesenteric artery syndrome (SMAS) is an intermittent or persistent passage obstruction that occurs in the third portion of the duodenum between the aorta and the superior mesenteric artery. After symptoms stabilize, the nutritional intake is started by ingesting a small amount. Recently, an energy-dense, low-volume nutritional food, Terumeal uplead® (Terumo Corporation, Tokyo, Japan) with an energy density of 4.0 kcal/mL, was launched. We report a case of a postoperative SMAS patient who was successfully treated using Terumeal uplead® through gastrostomy. An 83-year-old man who developed adhesive intestinal obstruction underwent right hemicolectomy, lysis of adhesion, and partial small bowel resection. Gastric distension persisted after surgery; thus, gastrostomy was performed for decompression and enteral nutrition on the 21st postoperative day, and enteral feeding was started on the 23rd postoperative day. However, fluoroscopy showed obstruction in the third portion of the duodenum, which was considered to be SMAS. To reduce the administration volume, enteral nutrition was replaced with Terumeal uplead® from the 28th postoperative day (intermittent administration thrice a day, 300 mL, 1,200 kcal per day). From the 34th postoperative day, the gastrostomy tube was clamped for two hours after administration, and no drainage was observed. Oral intake was resumed from the 36th postoperative day, and it was used in combination with enteral nutrition. Three months later, the patient was discharged home and continued oral ingestion with occasional decompression from the gastrostomy tube. Thus, Terumeal uplead® may be useful during the conservative treatment of SMAS by initiation with small amounts.

[A case of obstructive jaundice and duodenal stenosis caused by vaginal cancer and retroperitoneal metastasis].

A 76-year-old woman with a history of radiation therapy for vaginal cancer was referred to our hospital because of fever and hepatobiliary dysfunction. Computed tomography showed stenosis of the lower bile duct and edema-like changes in the duodenum from the descending to transverse parts. Endoscopic biliary stenting was performed according to the rendezvous method. Squamous cell carcinoma, similar to vaginal cancer, was found on pathological examination of the duodenum. We accordingly diagnosed obstructive jaundice and duodenal stenosis caused by vaginal cancer and retroperitoneal metastasis. To the best of our knowledge, other such cases have not been reported.

Use of antipyretics for preventing febrile seizure recurrence in children: a systematic review and meta-analysis.

The efficacy of antipyretics for preventing febrile seizure recurrence has been reported by a recent study, and the results might overturn previous evidence. We systematically reviewed the efficacy of antipyretics in the prevention of febrile seizure recurrence in children focused on the timing of its administration. We searched the Medline, Embase, and Cochrane Central Register of Controlled Trials databases for randomized and quasi-randomized trials and prospective non-randomized studies of aged up to 60 months, diagnosed with febrile seizure, who were treated with antipyretics. Data were extracted from eight studies. Only one study reported that antipyretics prevented the recurrence of febrile seizures within the same fever episode (9.1% in the acetaminophen group vs. 23.5% in the control group, p < 0.01). Four studies found no evidence for the efficacy of antipyretics in preventing febrile seizure recurrence in distant fever episodes (odds ratio, 0.92; 95% confidence interval, 0.57-1.48, for two randomized controlled studies).Conclusion: This review provides very limited support for the use of antipyretics in preventing febrile seizure recurrence within the same fever episode and no evidence for its use in distant fever episodes. New studies are required to evaluate this topic further and determine whether the effectiveness of antipyretics is based on intervention timing. What is Known: • Reviews of prophylactic drug management among febrile seizure children found that antipyretics had no significant benefits. • Recent data suggest that antipyretics are effective in preventing febrile seizures. What is New: • Weak evidence suggests a possible role in preventing febrile seizure recurrence within the same fever episode. • There is clearly no role for antipyretic prophylaxis in preventing febrile seizures during distant fever episodes.

Risk factors for de novo hepatitis B during solid cancer treatment.

BACKGROUND: Reactivation of hepatitis B virus (HBV) during anticancer treatment is a critical issue. When treating patients with solid tumors, it is unclear whether specific cancer types or treatments affect HBV reactivation in hepatitis B surface antigen (HBsAg)-negative and hepatitis B core antibody (HBcAb)-positive patients, so-called de novo hepatitis B patients. The risk of de novo hepatitis B may vary based on different background factors. AIM: To determine the frequency and risk factors for de novo hepatitis B during solid tumor treatment. METHODS: This retrospective cohort study comprised 1040 patients without HBsAgs and with HBcAbs and/or hepatitis B surface antibodies (HBsAbs). The patients were treated for solid cancer from 2008 to 2018 at the National Kyushu Cancer Center and underwent HBV DNA measurements. Patient characteristics and disease and treatment information were investigated. HBV DNA measurements were performed using TaqMan polymerase chain reaction (PCR). To identify the risk factors associated with HBV DNA expression, the age, sex, original disease, pathology, treatment method, presence or absence of hepatitis C virus (HCV), and HBsAb and/or HBcAb titers of all subjects were investigated. In patients with HBV DNA, the time of appearance, presence of HBsAgs and HBsAbs at the time of appearance, and course of the subsequent fluctuations in virus levels were also investigated. RESULTS: Among the 1040 patients, 938 were HBcAb positive, and 102 were HBcAb negative and HBsAb positive. HBV DNA expression was observed before the onset of treatment in nine patients (0.9%) and after treatment in 35 patients (3.7%), all of whom were HBcAb positive. The HBV reactivation group showed significantly higher median HBcAb values [9.00 (8.12-9.89) vs 7.22 (7.02-7.43), P = 0.0001] and significantly lower HBsAb values (14 vs 46, P = 0.0342) than the group without reactivation. Notably, the reactivated group showed a significantly higher proportion of cancers in organs related to digestion and absorption (79.0% vs 58.7%, P = 0.0051). A high HBcAb titer and cancers in organs involved in digestion and absorption were identified as independent factors for HBV reactivation (multivariate analysis, P = 0.0002 and P = 0.0095). The group without HBsAbs tended to have a shorter time to reactivation (day 43 vs day 193), and the frequency of reactivation within 6 mo was significantly higher in this group (P = 0.0459) than in the other group. CONCLUSION: A high HBcAb titer and cancers in organs involved in digestion and absorption are independent factors that contribute to HBV reactivation during solid tumor treatment.

Effectiveness of antiplatelet therapy for Kawasaki disease: a systematic review.

Kawasaki disease is an acute systemic vasculitis in children. Antiplatelet medicines are commonly used for Kawasaki disease to attenuate vasculitis and prevent thromboembolism; however, the mechanisms have not been elucidated. The objective of this study is to assess the effectiveness of antiplatelet medications for Kawasaki disease. We used Medline, Embase, Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi (Ichushi) from January 1947 to August 2018. Studies describing the platelet functions of antiplatelet drugs for Kawasaki disease were included. Twenty studies met the inclusion criteria. There were no randomized controlled trials. Seven studies compared platelet aggregation ability before and after treatment. Eight studies compared platelet aggregation with that in Kawasaki disease patients without treatment. Four studies compared aggregation among different types of antiplatelet drugs or at different doses. Antiplatelet medications administered in the studies included aspirin, flurbiprofen, dipyridamole, and choline salicylate. Methods for the measurement of platelet aggregation ability varied among studies. The groups with antiplatelet treatment tended to have a decreased platelet aggregation function. The statistical analyses were impossible due to insufficient quantitative data and heterogeneity among the studies.Conclusion: The present systematic review revealed that there was insufficient evidence for the effectiveness of antiplatelet therapy for Kawasaki disease. What is Known: • Antiplatelet therapy is widely used for Kawasaki disease to mitigate cardiac complications. • The mechanisms of antiplatelet therapy for Kawasaki disease are not clarified. What is New: • This systematic review showed that the groups with antiplatelet treatment tended to have a decreased platelet aggregation function. • There is insufficient evidence for the effectiveness of antiplatelet therapy for Kawasaki disease.

[A case of a patient with bile secretion disorder for whom an egg yolk lecithin-containing liquid diet was used for enteral nutrition].

For elderly people who are difficult to operate, percutaneous transhepatic gallbladder drainage (PTGBD) is conducted instead. In PTGBD, the bile is drained externally and impaired absorption of fat is a concern. Egg yolk lecithin, which is a fat emulsifier, is not easily broken in emulsion even under a low-pH condition, and the emulsified state is stable. Even in bile duct ligation rats, the emulsifier in egg yolk lecithin emulsion is reported to be superior to lipid absorption using other emulsifiers. Emulsification with egg yolk lecithin may possibly contribute to improvement of nutrition during biliary excretion disorders such as external drainage. We report a case of good progress with enteral nutrition with egg yolk lecithin-mixed liquid diet after PTGBD for acute cholecystitis. The patient was an 80-year-old man with a history of myocardial infarction and dementia. He was diagnosed with calculous cholecystitis, and conservative treatment was started. His cholecystitis was exacerbated, and PTGBD was performed on day 12 of the disease. On imaging, the lower extremities of the duodenum were edematous because of the spread of inflammation. Glutamine preparation alone was administered after resuming fasting. A liquid diet containing egg yolk lecithin, 200 ml of K-LEC (1 kcal/ml), was started from day 23, and was administered three times daily. Liquid diet dose was increased to 1,200 kcal/day with added dietary fiber on day 29. The patient's overall condition improved, and transthyretin level and body weight increased. Thereafter, after swallowing training, the patient was switched to oral meal intake from day 37.

Enteral Nutrition With an Enteral Formula Containing Egg Yolk Lecithin After Percutaneous Endoscopic Gastrostomy: A Case Series.

The occurrence of diarrhea at the beginning of enteral nutrition complicates the continuation of enteral nutrition. Recently, studies in Japan indicated that diarrhea could be improved by changing the enteral formula to one that is emulsified with egg yolk lecithin. In this study, we administered the enteral formula K-2S plus, which is emulsified with egg yolk lecithin, to 15 patients (four men and 11 women; mean age, 79.9 ± 2.0 years) after they had undergone a percutaneous endoscopic gastrostomy (PEG) to prevent the occurrence of diarrhea related to enteral nutrition. Two days after the PEG, the patients would receive 200 mL K-2S plus intermittently three times daily; thereafter, the amount of K-2S plus was increased according to the patient's condition. The administration rate was scheduled as 200 mL/h when 200 mL were administered at one time. For ≥ 300 mL, the scheduled administration rate was 300 mL/h. When we administered K-2S plus at the beginning of enteral nutrition after the PEG, the dose of the enteral formula could be increased without any occurrence of diarrhea or vomiting. Five patients had received intravenous nutrition before the PEG; thus, we were concerned about diarrhea in these patients. In conclusion, an enteral formula emulsified with egg yolk lecithin may be safely used at the time of enteral nutrition initiation without causing diarrhea.

An Advanced Well-differentiated Pancreatic Neuroendocrine Carcinoma (NET-G3) Associated with Von Hippel-Lindau Disease.

A 45-year old woman who underwent several surgeries for tumors associated with von Hippel-Lindau disease (VHL) was referred to our hospital due to a pancreatic tumor and liver tumors. She was diagnosed with pancreatic neuroendocrine tumor (NET) with a Ki67 index of 40% based on the examination of a biopsy specimen of the liver tumors. She was treated with everolimus for 6 months and sunitinib for 6 weeks as first- and second-line therapies. She survived for 13 months. At autopsy the diagnosis of pancreatic neuroendocrine tumor (NET)-G3 was confirmed. We herein report an aggressive clinical course of VHL-related NET G3. The further accumulation of cases is required to reach a consensus on treatment for this disease.

Epileptic spasms secondary to acute cerebral and cerebellar encephalitis.

BACKGROUND: Patients with infection-related acute encephalitis sometimes develop epilepsy in the chronic phase of the disease. Patients with postencephalitic epilepsy usually develop partial seizures due to the lesions generated by the encephalitis. We report a case who developed late-onset epileptic spasms after acute cerebral and cerebellar encephalitis. CASE REPORT: A 5-year-old girl showed severe tremor, gait ataxia, partial or generalized tonic-clonic seizures, hyperactivity, and panic attacks after a mild enterocolitis. Her cerebellar symptoms disappeared until 3 months after onset, and her seizures were controlled with carbamazepine. However, the seizures reappeared as epileptic spasms 5 months after onset. The anti-NMDA-type glutamate receptor antibody concentration was significantly elevated in her cerebrospinal fluid at 8 days, 10 months, and 15 months after onset. The spasms were resistant to multiple antiepileptic drugs. High-dose methylprednisolone and high-dose immunoglobulin therapies did not show any benefits. Oral pranlukast hydrate was started 17 months after onset. After 3 weeks of the medication, her seizures disappeared, and her behavior also dramatically improved. CONCLUSION: We presented a rare case of post-encephalitic epilepsy that manifested as epileptic spasms. Pranlukast significantly improved her seizures.

[Resumption of enteral nutrition using enteral formula containing sodium alginate following hemorrhaging after endoscopic sphincterotomy: a case report].

Enteral nutrition is often performed in elderly patients with dysphagia. Choledocholithiasis is a disease that is common in elderly patients. Gastrointestinal hemorrhaging can occur in association with endoscopic sphincterotomy, and subsequent enteral nutrition must be carefully resumed. We herein report our experience using Mermed Plus containing sodium alginate after endoscopic hemostasis. The patient was an 88-year-old woman with an onset of gallstone cholangitis during rehabilitation after cerebral infarction. On day 2, endoscopic sphincterotomy and biliary drainage were performed, and the cholangitis was ameliorated. The degree of arousal and swallowing function were unstable, and a liquid diet via the nasogastric tube was initiated from day 6. Anemia progressed on day 7, and melena was observed; as a result, the intravenous administration of a proton pump inhibitor was initiated. On day 8, endoscopic hemostasis of the ulcer proximal to the papilla was performed. From day 10, we focused on the mucosal protective effects of sodium alginate, and Mermed Plus was initiated. No recurrence of hemorrhaging was observed. On day 13, the endoscopic findings revealed that the vicinity of the papilla was covered with solidified liquid diet, and the ulcer had healed. The postoperative course was uneventful, and swallowing training and rehabilitation were performed. On day 26, oral ingestion became possible. Many patients seem to be at risk of developing a gastrointestinal mucosal disorder when receiving enteral nutrition. In such cases, a liquid diet containing sodium alginate as dietary fiber is easy to use and may be useful for resuming enteral nutrition without delay.

Continuation of Enteral Nutrition and Relief from Vomiting by Administration of a New Formula: a Case Report.

Gastro-esophageal reflux (GER) is a common and serious complication in patients receiving enteral nutrition, making continuation of enteral nutrition difficult. Semi-solid enteral nutrients were developed to prevent feeding-related GER. Semi-solid enteral nutrients have high viscosity and, therefore, are typically administered through a large-diameter percutaneous endoscopic gastrostomy (PEG) tube. Recently, a new formula (Mermed®, Mermed Plus®) was introduced that uses alginate, which behaves like a gelatin in acidic conditions. This formula improved GER during enteral feedings. Our case report shows that this new formula enables the continuation of enteral nutrition via a nasogastric tube (NGT) in patients with difficulty tolerating enteral nutrition secondary to vomiting. An 86-year-old woman with an atherothrombotic cerebral infarction vomited during tube feeding, resulting in aspiration pneumonia. After 1 week, we introduced a viscosity regulator and restarted enteral feeding using a 100 mL liquid diet, but vomiting persisted. Because of the continued difficulty in tolerating enteral nutrition, the patient was transferred to our hospital. From hospital day 4, Mermed Plus® (300 mL/225 kcal, administered for 1 hour, 3 times a day) was started, eventually increasing to 535 mL/400 kcal at hospital day 5. After this, vomiting ceased. Mermed Plus® was easily administered via NGT, and its effects were immediate. This treatment appeared to improve the patient's quality of life while reducing the burden on medical staff.
