Infectious diseases of the upper gastrointestinal tract are rare, but certain bacteria including Treponema pallidum and Mycobacterium tuberculosis may infect the esophagus, stomach, and duodenum even in an immunocompetent individual. Gastric syphilis is difficult to diagnose because it presents with non-specific symptoms and diverse endoscopic findings. Nevertheless, gastric syphilis should be considered in the differential diagnosis when a patient presents with chronic inflammatory gastric lesions such as multiple erosive/ulcerative lesions and stricture or with other evidence of syphilis. Histological evaluation and specific serological tests should be performed if syphilis is suspected. Esophageal and gastroduodenal tuberculosis also exhibits non-specific clinical manifestations. The diagnosis is confirmed by mucosal biopsy or aspiration cytology revealing the presence of caseating granulomata and/or acid-fast bacilli. Mycobacterial culture and polymerase chain reaction should be incorporated into routine diagnostic studies to improve the diagnostic sensitivity. The diagnosis of tuberculosis is occasionally confirmed indirectly by an excellent response of the patient to anti-tubercular therapy.

Further understanding of male human papillomavirus (HPV) infection is necessary to prevent infection in men, as well as transmission to women. In our current study, we investigated patterns of HPV infection and genotype distributions in male genital warts using the Anyplex II HPV28 Detection kit. We reviewed the medical records of 80 male patients who presented to 5 neighborhood clinics in Ulsan, Korea, for the treatment of genital warts between April 2014 and January 2015. All patients underwent HPV genotyping. The prevalence and characteristics of HPV infection were analyzed, and the patterns of HPV infection according to age were assessed. Among the study patients, 13 (16.3%) were negative for HPV infection, 46 (57.3%) were infected with low-risk HPV, and 21 (26.3%) were infected with high-risk HPV. Patients with multiple HPV infection were more likely to have high-risk HPV infection (P = 0.001). The prevalence of HPV infection was much higher in samples obtained by tissue excision due to a definite lesion (P = 0.001). There were no differences in high-risk HPV infection (P = 0.459), multiple HPV infection (P = 0.185), and recurrence at diagnosis (P = 0.178) according to age. HPV-6 and HPV-11 were the most common type overall (39.7% and 13.8%, respectively). HPV-16 and HPV-18 were the most common high-risk infections (both 3.4%). HPV infection is not only commonly encountered in male genital warts, but is also accompanied by high-risk HPV and multiple infections.

This study was aimed to assess the free calcium status with or without its direct measurement in patients on hemodialysis(HD: n=27) and malnourished ones from extrarenal diseases(MN: n=14). It was performed by the comparison of measured free calcium (Ca++m) levels by gas analyzer and calculated free calcium(Ca++c) levels based on those of total calcium (TCa), albumin, and pH with the modified algorithm invented by Moore(J Clin Invest. 49:318, 1970). Of 27 HD pts, 14(5296) had low[Ca++m] below 1.05mmol/L despite only 2(796) with low [TCa] below 2.05mmoV L, whereas 14 MN pts had similar numbers between low[Ca++m] and low[TCa]. Compared to MN pts, HD pts showed significantly lower mean levels(SE) of pH(7.37 0.01 vs. 7A4 0.01, p<0.01), higher[TCa](2.33 0.04 vs. 1.83 0.08mmol/L, p<0.01), and higher albumin (4.33 0.06 vs. 2.59 0.17mg/dL, p<0.01).However, [Ca++m] between 2 groups did not reveal any significant difference. Furtherrnore, in total 41 pts of 2 groups, no similarity was observed between the values of [Ca++ml and [Ca++c] but with their significant difference(p<0.05). Only[TCa] was significantly corre- lated with albumin level(r=0.73, p<0.01). Furthermore, multiple regression analysis between [Ca++m] and other factors including pH and albumin didn't show any correlation. In conclusion, this data suggests that relatively high prevalence of low values of physiologically important free ionized calcium in chronically ill pts, especially on maintenance HD, could be missed when predicted on total calcium level, and pH without its direct measurement.

PURPOSE: This study was performed to evaluate the usefulness of abdominal computed tomography (CT) for patients with right lower quadrant (RLQ) pain. METHODS: Between January 2006 and July 2008, 191 consecutive patients with RLQ pain underwent abdominal CT (CT group). Forty-two patients who had undergone abdominal ultrasound (US group) and 52 patients without abdominal CT or abdominal ultrasound for RLQ pain (clinical Dx group) underwent emergent operations. Using the Alvarado scoring system, we scored all patients. The abdominal CT was performed in the abdominal and pelvic area with contrast. RESULTS: One hundred twenty-one (63.4%) of the 191 patients in the CT group were preoperatively diagnosed as having acute appendicitis and underwent surgery. There were three cases of negative appendectomy (1.6%). In the US group and the clinical Dx group, the negative appendectomy rates were 4.8% and 3.8%, respectively. The sensitivity of the abdominal CT was 96.7%. In the CT group, in addition to acute appendicitis, colitis, nonspecific enteritis, diverticulitis, urinary stone, ovary, uterine, and diseases were indentified. CONCLUSIONS: In this study, abdominal CT scans in patients with RLQ pain were useful for the diagnosis acute appendicitis and for the differential diagnosis of other diseases presenting with RLQ pain. The false positive rate was significantly lower in the CT group than in the other groups.
