Diabetic gastroparesis-associated bezoar resolution via "cola-lysis"

Abstract:  Phytobezoars associated with diabetic gastroparesis are often sources of diminished quality of life for patients. Poor blood sugar control has been associated with increasing gastroparesis. For recipients of pancreas transplants to correct diabetes, phytobezoar treatment post-transplant can typically be limited to invasive procedures and prokinetic agents. We present the case of an alternative treatment to phytobezoar, cola libation, i.e., "cola-lysis."

Fecal impaction in children: report of 53 cases of rectal seed bezoars

Background

Rectal seed bezoars in children seem to present an uncommon problem that necessitates some operative intervention.

Purpose

Our objective is to determine the occurrence and clinical characteristics of rectal seed bezoars in children with fecal impaction.

Methods

A retrospective review of hospital records of children with discharge diagnosis of fecal impaction was conducted from 1996 to 2005 in a university-affiliated general hospital

Results

The study group is composed 59 children. A total of 53 had rectal seed bezoars: watermelon seeds in 43 children, prickly pear seeds in 6, sunflower seeds in 3, and pumpkinseeds in 1. Six children had seedless fecal impaction. All the children with seed bezoars were of Arab origin. Fifty children were treated under general anesthesia. Of the remaining 9 children, 5 underwent digital disimpaction without general anesthesia: 3 with seedless feces and 2 with rectal seed bezoars. Four children with rectal seed bezoars evacuated spontaneously without digital disimpaction. There was summer seasonal preference for watermelon and prickly pear seed bezoars, whereas sunflower seed bezoars occurred in the spring.

Conclusions

Fecal impaction owing to rectal seed bezoars is more common than previously believed. Its occurrence among Arab children alone in this study might indicate a high proportion of fecal seed bezoars throughout the Middle East. We propose that the preferred treatment should include disimpaction and irrigation of the rectal content under anesthesia. Greater awareness by primary care practitioners and parents might be beneficial in its prevention in the future.     

Color Doppler twinkling artifacts in small-bowel bezoars

Small-bowel bezoars usually form in the stomach and may subsequently cause small-bowel obstruction. Bezoars associated with small-bowel obstruction have been accurately diagnosed by computed tomography, although some case reports have described the specific sonographic findings of small-bowel bezoars. Bezoars can be overlooked by sonographic examination if a dilated small-bowel loop contains a large amount of air. Twinkling artifacts on color Doppler images appear as rapidly fluctuating red and blue signals behind certain strongly reflecting structures. In this series, we hypothesize that twinkling artifacts might appear in small-bowel bezoars, and we describe the presence of twinkling artifacts in 3 cases of small-bowel bezoars presenting as small-bowel obstruction.     

生殖道感染与先兆流产关系的临床研究

目的 探讨生殖道念珠菌、解脲支原体（UU）和沙眼衣原体（CT）感染与先兆流产之间的关系。方法 先兆流产患者70例作为研究组，同期随机抽取60例正常早孕妇女作为对照组，已婚未育妇女50例作为正常组。对三组妇女进行了白带常规的检测，其中念珠菌检测采用直接镜检法。同时使用培养法检测UU，聚合酶链反应（PCR）法检测CT。结果 研究组、对照组、正常组妇女白带常规中白细胞超标率分别为60％、36．7％、12％，清洁度超标率分别为57．1％、33．3％、14％，念珠菌阳性率分别为22．9％、26．7％、10％，UU阳性率分别为32．9％、40％、38％；CT阳性率分别为21．4％、13．3％、3．3％；CT＋UU阳性率分别为11．4％、3．3％、4％。结论 生殖道CT和UU＋CT混合感染与先兆流产密切相关。

A safe treatment option for esophageal bezoars

INTRODUCTIONBezoar in the esophagus is a rare condition and associated with structural or functional abnormalities of the esophagus. Endoscopy is the main tool for diagnosis and treatment for bezoar in the esophagus.PRESENTATION OF CASEHere we present a case where an endoscopic evacuation of an esophageal bezoar was unsuccessful. We treated the bezoar through a nasogastric tube using a cocktail composed of pancreatic enzymes dissolved in Coca-Cola.DISCUSSIONEndoscopy is regarded as the mainstay for the diagnosis and treatment of esophageal bezoars. However, when this approach fails, other treatment options include dissolution therapy, and surgical exploration and removal of the bezoar. Surgical removal of an esophageal bezoar is associated with a high risk of morbidity and mortality. We advocate that dissolving therapy should be the first choice of treatment when endoscopic evacuation is not possible.CONCLUSIONThis is the first report describing a successful treatment of an esophageal bezoar with a cocktail of Coca-Cola and pancreatic enzymes. It is an effective, inexpensive, and worldwide available treatment and should be considered when endoscopic evacuation fails.
