  • Globus pharyngeus or globus sensation is the painless sensation of a lump in the throat and may be described as a foreign body sensation, a tightening or choking feeling. It is often associated with persistent clearing of the throat, chronic cough, hoarseness, and catarrh. Its etiology remains unclear ; however, laryngopharyngeal reflux may play a role in a subset of patients. Psychogenic problems have often been thought to cause or trigger the globus sensation. Personality studies have found higher levels of alexithymia, neuroticism, and psychological distress (including anxiety, low mood, and somatic concerns) and lower levels of extraversion in patients presenting with globus. Globus patients with laryngopharyngeal reflux exhibited weaker psychological symptoms than non- laryngopharyngeal reflux globus patients, and globus patients who did not respond to proton pump inhibitor had significantly higher anxiety scores. In cases with negative clinical investigations and consistent globus symptom, other treatment strategies, including speech therapy, antidepressants, and cognitive-behavioral therapy, should be considered.

  • Gastro-esophageal reflux disease (GERD) is a recurrent, long-term gastrointestinal condition characterised by the abnormal reflux of stomach contents into the esophagus. Heartburn is the most dominant symptom, which can be life long and can considerably reduce quality of life. The main goals of treatment are to alleviate symptoms and prevent relapses, esophageal stricture and adenocarcinoma. This paper presents a review comparing the effectiveness of omeprazole with Nissen fundoplication surgery for the treatment of GERD. Nissen fundoplication is more effective in controlling heartburn symptoms, healing esophagitis and preventing relapses than omeprazole. Quality of life, in terms of productivity and ability to work, is difficult to assess in the omeprazole group and, as a result, a comparison of this aspect is limited. Although fundoplication is expensive in the short term, it is more cost-effective than omeprazole. Nurses need to be aware of the effectiveness of omeprazole and fundoplication to provide patients with accurate information, which assists patients in decision making regarding treatment options.

  • Urinary tract infection (UTI) is a common bacterial illness in children. Acute pyelonephritis in children may lead to renal scarring with the risk of later hypertension, preeclampsia during pregnancy, proteinuria, and renal insufficiency. Until now, vesicoureteral reflux (VUR) has been considered the most important risk factor for post-UTI renal scar formation in children. VUR predisposes children with UTI to pyelonephritis, and both are associated with renal scarring. However, reflux nephropathy is not always acquired; rather, it reflects reflux-associated congenital dysplastic kidneys. The viewpoint that chronic kidney disease results from renal maldevelopment-associated VUR has led to questioning the utility of any regimen directed at identifying or treating VUR. Despite the recognition that underlying renal anomalies may be the cause of renal scarring that was previously attributed to infection, the prevention of renal scarring remains the goal of all therapies for childhood UTI. Therefore, children at high risk of renal scar formation after UTI should be treated and investigated until a large clinical study and basic research give us more information.

  • Objectives This study was designed to report treatment of Soyangin Mangeum with gastroesophageal reflux disease. Methods We treated two patients suffering from dyspepsia and chest discomfort. A female patient was treated with Hyeongbangjiwhang-tang. A male patient was treated with Hyungbangsabaek-san. The progress was evaluated with the visual analogue scale for dyspepsia, chest discomfort, and other symptoms. Results A female patient's symptoms such as dyspepsia, chest discomfort were almost cured. but they increased with patient's emotional state repeatedly. A male patient' symptoms such as abdominal pain, dyspepsia, nausea, heart burn was successfully disappeared. Conclusions Hyeongbangjiwhang-tang and Hyungbangsabaek-san can be considered as a treatment for patient with Soyangin Mangyin diagnosed as gastroesophageal reflux disease.

  • The pathophysiology of Gastroesophageal reflux disease (GERD) has been known that it is developed when the offense-primarily the gastric acid-pepsin content of the refluxate-overcomes a 3-tiered esophageal protective defense. consisting of antireflux mechanisms, luminal clearance mechanisms, and tissue resistance. Laryngopharyngeal reflux (LPR), which is known as an extraesophageal variant of GERD, has been considered to be developed by transient lower esophageal sphincter relaxation (TLESR), direct mucosal injury by gastric contents, more sensitive mucosa compared to esophagus, and absence of buffering effect and aggravation of the injury due to pepsin. However, hypothesis of the pathophysiology in both entities are numerous and still lack of understanding for being a theory. There is no conflict that understanding the pathophysiology is necessary for resolving the problems of these diseases and numerous studies and results have been releasing. This review could provide clinicians dealing with GERD and LPR with applicable new information and help for overcoming the clinical obstruction.

  • Objectives: The aim of this study was to determine the therapeutic effects of a traditional Korean treatment on the symptom improvement and loss of bile juice in cases of functional dyspepsia of gastric dysmotility complicated by bile juice reflux. Methods: Dyspeptic symptoms, gastric motility (electrogastrography and bowel sound analysis), and gastric mucosa (gastroendoscopy) were evaluated. The treatment consisted of Banwhasashim-tang (extract) used as a herbal drug. Both ST36 electrical stimulation and simple immersion stimulation of CV11, 12, and 13 in the abdomen were also applied. Results: Dyspeptic symptoms, including a foreign body sensation in the throat, indigestion, and upper abdominal pain, were all relieved by the treatment and gastric myoelectrical activity and gastric pyloric function were improved. Bile juice disappeared from the gastric mucosa. Conclusion: The traditional Korean treatment was effective at relieving dyspeptic symptoms and bile juice reflux by improving the pyloric sphincter function.

  • Patients with vesicoureteral reflux (VUR), the retrograde flow of urine from the bladder to the kidney, are known to experience renal scarring; this results in the worsening of renal function. Reflux nephropathy is a cause of chronic kidney disease, and VUR has also been observed in dialysis patients. VUR is a major underlying precursor condition of urinary tract infection (UTI) and is sometimes accompanied by hydronephrosis. However, there are no guidelines for the management of UTI due to VUR-associated hydronephrosis in patients with end-stage kidney disease. Herein, we report a case of UTI caused by VUR-associated hydronephrosis in a dialysis patient treated with percutaneous nephrostomy.

  • Kleefstra syndrome is a rare genetic disease characterized by mental retardation, hypotonia, and a characteristic facial appearance. Furthermore, in some cases, Kleefstra syndrome is associated with various anorectal and genitourinary complications, including imperforated anus, vesicoureteral reflux, hydronephrosis, and chronic kidney disease. Herein, we present a case of Kleefstra syndrome with recurrent urinary tractinfections associated with vesicoureteral reflux and rectourethral fistula, which was treated by a multidisciplinary approach.
