Abstract
BACKGROUND & AIMS Guidelines recommend measuring antibody (Ab) titers to hepatitis B virus (HBV) after vaccination for patients with inflammatory bowel disease (IBD) or celiac disease (CD) ("patients with IBD/CD") and revaccinating when titers are low. Few data, however, support this recommendation. We aimed to compare effectiveness of HBV vaccination (immunity and infection rates) for patients with IBD/CD vs matched referents. METHODS Using the Rochester Epidemiology Project, we performed a retrospective cohort study of patients first diagnosed with IBD/CD (index date) while residing in Olmsted County, Minnesota, from January 1, 2000, through December 31, 2019. HBV screening results were obtained from health records. RESULTS In 1264 incident cases of IBD/CD, only 6 HBV infections were diagnosed before the index date. A total of 351 IBD/CD cases had documented receipt of 2 or more HBV vaccines before their index date and had hepatitis B surface antigen Ab (anti-HBs) titers measured after their index date. The proportion of patients with HBV-protective titers (≥10 mIU/mL) decreased with time before plateauing, with protective titer rates of 45% at 5 up to 10 years and 41% at 15 up to 20 years after the last HBV vaccination. The proportion of referents with protective titers also decreased with time and was consistently higher than the levels of patients with IBD/CD within 15 years after the last HBV vaccination. However, no new HBV infection developed in any of 1258 patients with IBD/CD during a median follow-up of 9.4 years (interquartile range, 5.0-14.1 years). CONCLUSIONS Routine testing of anti-HBs titers may not be indicated for fully vaccinated patients with IBD/CD. Additional studies are needed to confirm these findings in other settings and populations.

Abstract
BACKGROUND Children with perianal fistulizing Crohn disease require intensive medical management but also have a higher risk for subsequent surgical interventions. OBJECTIVE We performed a retrospective study to identify patient factors and perianal anatomical features by pelvic MR that are associated with surgical interventions in these children. MATERIALS AND METHODS We included children with Crohn disease and perianal fistula who underwent pelvic MR with available, archived images and collected demographic, clinical and laboratory data. Radiologists reviewed pelvic MR exams and identified Park classification and additional anatomical features of perianal fistulas, including fistula branching, horseshoe ramifications, abscess, inflammatory mass, supralevator extension, anal sphincter damage, proctitis and posterior anal space involvement. We performed univariate and subsequent multivariate analysis to determine features associated with subsequent surgical intervention. RESULTS Ninety-nine children with Crohn disease underwent pelvic MR. In this cohort, 69 children had no surgical interventions prior to baseline MRI, with subsequent median clinical follow-up of 5.5 years. Univariate analysis demonstrated that branching (P=0.009), supralevator extension (P=0.015) and anal sphincter damage (P=0.031) were significantly associated with subsequent surgical intervention. Age at baseline MRI was also associated with intervention (hazard ratio [HR] every 5 years: 2.13; 95% confidence interval [CI]: 1.18-3.83; P=0.012). A multivariable model identified only fistula branching (HR: 2.31; 95% CI: 1.28-4.15; P=0.005) and age (HR: 5.18; CI: 1.57-17.14; P=0.007) as independent predictors of subsequent surgery. No demographic, clinical or laboratory parameter predicted subsequent surgical intervention. CONCLUSION Age and anatomical MR features indicating fistula complexity (branching, supralevator extension) and sphincter damage confer a higher risk of subsequent surgical intervention in children with perianal Crohn disease.

Abstract
The antimicrobial potency of 4 per cent chlorhexidine gluconate was compared with that of 10 per cent povidone-iodine (1 per cent free iodine) on the vaginal bacteria of 150 premenopausal, non-pregnant women. From 30 of the women blood samples were taken before and at either 15, 30 or 60 minutes after vaginal cleansing with chlorhexidine for chlorhexidine analysis. Five minutes after applying either chlorhexidine or povidone-iodine almost 99 per cent of bacteria present on the lateral wall of the vagina were killed. Chlorhexidine was significantly more effective than povidone-iodine. Serosanguineous , mucoid or white-yellowish vaginal discharge did not alter the effectiveness of either antimicrobial agent. In contrast to povidone-iodine, vaginally applied chlorhexidine was not absorbed in measurable amounts (sensitivity of detection method: 0 X 1 mg/l) into the bloodstream. Chlorhexidine may therefore prove of value for treating vaginitis especially during pregnancy and also for combating microbes such as Group B streptococci which are potentially harmful to the newly-born child.

Abstract
The abnormal cutaneous flora of hemodialysis (HD) patients might contribute to their frequent septic complications. We compared the effects of 13 wk of Betadine and 13 wk of Hibiclens on the skin flora of HD patients and personnel. Skin cultures were obtained weekly immediately prior to the disinfection, preceding each triweekly HD treatment, and monthly, at 2 and 4 hr postdisinfection. Total bacterial counts from predisinfection cultures were not significantly altered over either 13-wk treatment period. Hibiclens reduced total bacterial counts (p less than 0.01) and eradicated cutaneous staphylococci (p = 0.032) at both 2 and 4 hr postdisinfection significantly more than did Betadine. No reduction of staphylococcal sensitivity to either germicidal agent could be demonstrated. Neither agent was associated with severe adverse reactions and Hibiclens could not be detected in the blood. Hibiclens appears to offer short-term advantages over Betadine in the HD setting because of significantly longer duration of antibacterial activity.

Abstract
Staphylococcal sepsis is a leading cause of morbidity and mortality among chronic hemodialysis (HD) patients. We studied nasal and cutaneous flora of HD patients and personnel and their patterns of staphylococcal carriage. HD patients had significantly increased cutaneous total bacterial colony counts (p less than 0.01) as well as both nasal (p less than 0.0001) and cutaneous (p less than 0.0001) carriage of Staphylococcus aureus compared to personnel. Cutaneous staphylococcal carriage could be significantly correlated with nasal carriage (p less than 0.01). Cutaneous streptococcal species and gram-negative bacilli were not different between patients and personnel. Staphylococcal phage typing of nasal isolates from staphylococcal carriers revealed a mean of 90% of isolates from each subject belonging to a predominant phage type. Predominant nasal staphylococcal phage types corresponded with respective predominant cutaneous phage types in 93% of HD patients carriers. These studies substantiate autoinoculation of S. aureus from the nasal vestibule to the skin overlying the vascular access site.

Abstract
In 12 nonpregnant women, total iodine, protein-bound iodine, inorganic iodine, and thyroxine values were measured in serum before and 15, 30, 45 or 60 minutes after a two-minute vaginal disinfection with povidone-iodine (Betadine). Only 15 minutes after application, serum iodine levels were raised and remained significantly elevated 30, 45 and 60 minutes after disinfection. Serum concentrations of total iodine and inorganic iodine were increased up to fivefold to 15-fold, respectively; during the relative short period of observation, thyroxine levels were not altered. An overload of iodine can suppress thyroid hormonogenesis, and the fetal and neonatal thyroid glands are especially sensitive. In pregnant women, vaginitis should not be treated with povidone-iodine because of the possible development of iodine-induced goiter and hypothyroidism in the fetus and newborn. The risk is especially high when povidone-iodine is used repeatedly.

Abstract
A study to identify putative bacterial pathogens in infants with necrotizing enterocolitis (NEC) was begun in 1976. Cultures of blood and of peritoneal fluid obtained by paracentesis were carried out in 25 infants with NEC. Segments of intestine excised at operation were Gram stained. Of the 25 infants, 8 recovered with medical management and 17 required operations. The 8 medically treated infants had sterile peritoneal fluid and, with 2 exceptions, sterile blood cultures. Of the 17 operated infants, 16 had bacteria in their blood and/or peritoneal fluid. The majority of resected bowel specimens from these infants contained a confirmatory morphologic type of bacterium within the wall. The clinical course of 8 infants with clostridia was compared to that of 8 infants with gram-negative enteric bacteria (Klebsiella, E. coli, or Bacteroides fragilis). The infants with clostridia were sicker. They had more extensive pneumatosis intestinalis, a higher incidence of portal venous gas, more rapid progression to gangrene, and more extensive gangrene. Infants with gram-negative rods had lower birth weights and lower platelet counts than the clostridial group. The difference in mortality between the two groups was not significant. The inherent pathogenicity of the gut flora may influence the clinical course of NEC. Among infants who develop intestinal gangrene, the clostridia appear to be more virulent than gram-negative enteric bacteria.

Abstract
The antimicrobial effects of two chlorhexidine preparations, Hibiclens and Hibitane Tincture, were evaluated in 154 obstetric patients. Both agents produced bacterial kills of over 99% on skin bacteria of groin and perineum ten and 30 minutes after their application. Five minutes after vaginal cleansing with Hibiclens more than 99% of bacteria originally present were destroyed. Even though both preparations proved to be potent bactericidal agents, Hibitane Tincture cannot be recommended as a perigenital antiseptic since it causes vulvar irritation due to its high isopropanol content. With Hibiclens application to groin and perineal skin no side effects were observed. In one of 51 patients treated vaginally with Hibiclens a rather strong burning sensation occurred, without any aftereffect. Hibiclens seems to be a promising antiseptic for obstetric and gynecologic patients.

Abstract
The cellular fatty acids (C11-C20) from 18 species and strains within the genera Microsporum, Trichophyton, and Epidermophyton were determined by gas liquid chromatography. In addition, the effects of incubation time and temperature on fatty acid composition were investigated in selected species. The dermatophytes investigated represented anthropophilic, geophilic, and zoophilic species. Linoleic (18:2), oleic (18:1), and palmitic acid (16:0), accounted for 83.6-94.5% of the fatty acids of dermatophytes. Fatty acid composition and degree of unsaturation did not show any correlations with taxonomic status or ecological group. Incubation time influenced fatty acid composition slightly, but tendencies towards unsaturation and chain elongation were not observed. Elevated incubation temperature (37 degrees C) tended to increase the degree of total fatty acid unsaturation.

Abstract
To evaluate the relative effectiveness of the treatment of tinea pedis, we performed a double-blind study comparing undecylenic acid ointment, tolnaftate cream, and a placebo. Ninety patients with clinically and mycologically proven tinea pedis took part in this clinical trial. Our results showed both agents to be superior to the placebo, but there was no significant difference in effectiveness between the two active agents. We observed no side effects with the preparations used.

Abstract
5 infants with no growth of bacteria on cultures of blood and peritoneal fluid recovered from necrotising enterocolitis after medical treatment alone. 12 infants with positive cultures required surgery. 5 of these 12, who did not harbour clostridia, had a mild clinical course and all 5 survived segmental bowel resection. The 7 infants who harboured clostridia had a more severe clinical course and 4 died. In 3 of 4 infants with Clostridium perfringens, the necrotising enterocolitis was fulminant, characterised by severe pneumatosis intestinalis, extensive gangrene, early intestinal perforation, and a fatal outcome.

One hundred and four patients with mycologically confirmed tinea pedis took part in a controlled clinical trial to determine the efficacy of undecylenic acid powder preparations in the treatment of their fungal infections. Clinical and mycological cures were obtained in 53% of those subjects treated with undecylenic acid powders as compared with 7% of those treated with the talc vehicle or left untreated. Undecylenic acid in a powder vehicle appears to be a safe and effective agent in the treatment of tinea pedis.

Abstract
A study of two neurosurgical operating rooms indicated a low, airborne, microbial population could be maintained by recirculating filtered air during surgical procedures. The commonly used turbulent system of air delivery was employed, and high-efficiency filters were effective in removing airborne bacteria generated within the operating room. Optimal rates and percent of recirculation were determined. The method of exhaust was confirmed to be important. Exhaust ports 40 in. above the floor were more effective in maintaining low airborne microbial populations than baseboard-level ports. The degree of activity of the surgical team and the number of personnel in the operating room correlated with the airborne bacterial counts.
