, by excluding other factors, 48 patients were included in the study, diagnosed as drug-induced esophagitis with their history, endoscopic view, and histopathologic evaluation. Results: There were 34 (70.9%) female and 14 (29.1%) male patients in the study, and their average ages were 35.1 and 32.4, respectively. Clinical symptoms were odynophagia (79.1%), retrosternal pain (62.5%), and dysphagia (47.9%). The reason for these symptoms for 85.5% of the patients was related to insufficient water consumption while taking the pill, taking the pill in recumbent position, or both. Tetracycline and its variant, doxycycline, were responsible for 52% of the patients, and 62.5% of the drugs were in capsule form. Ulcers were at the proximal and middle third of the esophagus in 79.2% of the patients. In the histopathologic evaluation, nonspecific acute inflammatory changes were found in 29.1% of the cases. Various proton pump inhibitors and sucralfate were used in the treatment. While no perforation and structure were detected, 1 patient died because of repetitive arterial bleeding. Conclusion: Almost every kind of drug, particularly doxycycline, can cause ulcer in the esophagus. Pill esophagitis can be prevented by warning patients about drinking water sufficiently and sitting up while taking the pill.

UTE is a useful tool for the evaluation of patients with advanced GI strictures. It provides a complete diagnostic endoscopy in most patients and gives an opportunity for therapeutic endoscopic procedures.

Background. Viruses are common and are involved in the etiology of idiopathic rheumatological diseases. Hepatitis B virus (HBV), a member of the family Hepadnaviridae and hepatitis C virus (HCV), play an important role in the undetermined etiology of arthritis. The clinical manifestations of hepatitis B and C show similarities with various diseases, such as rheumatic diseases. Anti-cyclic citrullinated peptide (anti-CCP) is a specific serological marker for rheumatoid arthritis.

The Interferon (IFN) which is the standard treatment for Hepatitis C, may cause a lot of side effects including dermatological anomalies. This paper presents a psoriasis case which occurred in relation with the treatment of acute hepatitis C (AHC) with peginterferon alfa (peg-IFN-α). A 60-year-old male patient came to the hospital with symptoms of high liver enzymes. The patient with history of a recent operation showed anti-HCV(+), HCVRNA 3.5 million IU/mL and HCV genotype 1b in the tests. Without any other etiological factors found in the patient, we started a treatment of peg-IFNα-2b with the diagnosis of AHC. After 3 weeks, psoriatic plaques were observed in various parts of the body. Antiviral treatment of the patient was concluded within 6 months. His psoriasis treatment initially commenced with local agents followed by phototherapy. Permanent viral response was seen in the patient and his lesions recovered rapidly after the antipsoriatic and antiviral treatment. Psoriasis and other autoimmune diseases should be considered even though they are encountered rarely,and the patients should be informed of the possible risks before planning treatment with peg-IFN-α.

Ghrelin and obestatin, two antagonist peptide hormones, are purportedly involved in stimulating appetite and controlling energy balance in humans. Serum ghrelin level is also associated with iron deficiency anemia (IDA), but no study has yet been made of the obestatin level in patients with IDA, even though both hormones are a single gene product. Therefore, the purpose of this investigation is to see whether there is a link between IDA and these two hormones among other hematological parameters in patients with IDA. To measure ghrelin and obestatin, human saliva and serum were collected from 30 women with IDA, aged 31.7 ± 10.7 years, and 30 control women, aged 30.2 ± 8.0 years, with repeated collection of samples over a period of 1 week and 1 month. Saliva and serum ghrelin levels were measured by ELISA. Serum hemoglobin, ferritin, hematocrit and total iron-binding capacity (TIBC) values were determined with an Olympus AU2700. Saliva and serum ghrelin and obestatin levels were significantly lower in the IDA group compared with controls; these levels increased slightly above baseline with iron treatment, but remained below the control values.Furthermore, and as expected, serum hemoglobin, ferritin, and hematocrit levels were 2 significantly increased with iron treatment, while total iron-binding capacity decreased compared to baseline concentrations. The findings suggest that IDA might be linked to imbalance of circulating (serum) and non-circulating (saliva) ghrelin and obestatin levels.Decreased ghrelin and obestatin might destroy iron homeostasis through its effect on intestinal absorption. Measuring these hormone levels might be useful for monitoring the response to iron treatment. Also, serum and saliva levels for both hormones were well correlated. Thus, using saliva in place of serum for monitoring the two hormones should minimize inconvenience and patient discomfort.

Methods To measure ghrelin and obestatin, human saliva and serum were collected from 30 women with IDA and 30 control women with repeated collection of samples over a period of 1 week and 1 month. Saliva and serum ghrelin levels were measured by enzyme-linked immunosorbent assay. Results Saliva and serum ghrelin and obestatin levels were significantly lower in the IDA group compared with controls; these levels increased slightly above baseline with iron treatment, but remained below the control values. Serum hemoglobin (Hb), ferritin and hematocrit (Hct) levels significantly increased with iron treatment, while total iron-binding capacity (TIBC) decreased compared to baseline concentrations. Conclusions The findings suggest that IDA might be linked to imbalance of circulating (serum) and non-circulating (saliva) ghrelin and obestatin levels. Using saliva in place of serum for monitoring the two hormones should minimize inconvenience and patient discomfort.
