Severe human urticaria produced by ant (Odontomachus bauri,Emery 1892) (Hymenoptera: Formicidae) venom

BACKGROUND: Ant sting reactions are becoming an increasing problem in tropical countries. It is important for physicians to be aware of their possible cutaneous and systemic manifestations. METHODS: A child with a severe allergic reaction to an ant sting was examined and is discussed. This is the first case described in the literature caused by the ant Odontomachus bauri, and the biology of the ant and the clinical signs in the patient are described. RESULTS: A child developed a strong allergic reaction to an ant sting. The case was not associated with a previous ant sting. Treatment with the systemic antihistamine loratadine (Clarityn) was favorable in this patient. CONCLUSIONS: In tropical areas, ant stings are usually benign, self-limited pathologic processes. In some cases, however, severe allergic reactions can develop, including urticaria and anaphylactic shock. Physicians should be aware of the possible complications of ant stings.     

Fiberoptic Endoscopic Evaluation of Swallowing in children: feeding outcomes related to diagnostic groups and endoscopic findings

Objective

Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is used as an adjunct to assess swallowing function in children with complex feeding disorders. We report the feeding outcomes of patients who underwent FEES to determine whether associations exist between clinical diagnoses or FEES findings and feeding outcomes.

Methods

Retrospective review of children who underwent FEES for dysphagia or aspiration from 2003 to 2009. The clinical diagnoses and initial FEES findings were compared to follow up feeding status for associations.

Results

79 patients were included (44 males and 35 females). The change from initial to final status: total oral feeding (42-67%), NPO ± minimal tastes (39-21%) and oral feeding with tube feeding (19-12%). Of the clinical diagnoses, tonsillar hypertrophy was associated with ultimately obtaining total oral feeding status (p = 0.046) while the inability to obtain total oral feeding status was associated with neurologic (p < 0.001). The initial FEES findings showed no significant associations with long-term feeding status.

Conclusion

Many children overcome their dysphagia but those with neurologic disorders are less likely to achieve total oral feeding status. In children with dysphagia evaluated by FEES, the long-term feeding status is not significantly associated with the initial FEES findings.

Maternal goals for childbirth associated with planned vaginal and planned cesarean birth

We describe maternal childbirth goals among women planning either cesarean or vaginal birth. Women in the third trimester planning cesarean or vaginal birth were asked to report up to five childbirth goals. Goal achievement was assessed postpartum. Based on free-text responses, discrete goal categories were identified. Goals and goal achievement were compared between the two groups. Satisfaction was rated on a visual analogue scale and was compared with goal achievement. The sample included 163 women planning vaginal birth and 69 women planning cesarean. Twelve goal categories were identified. Only women planning vaginal birth reported a desire to achieve fulfillment related to childbirth. Women planning cesarean were less likely to express a desire to maintain control over their own responses during childbirth and more likely to report a desire to avoid complications. The 72 women who achieved all stated goals reported significantly higher mean satisfaction scores than the 94 women reporting that at least one goal was not achieved (P = 0.001). Goal achievement was higher among women planning cesarean than among those planning vaginal birth (52.2% versus 23.1%, P < 0.001). This research furthers our understanding of women's attitudes regarding cesarean childbirth and definitions of a successful birth experience.     

The association between race and prostate cancer risk on initial biopsy in an equal access,multiethnic cohort

Purpose

Population-based studies have established a link between race and prostate cancer (PC) risk, but whether race predicts PC after adjusting for clinical characteristics is unclear. We investigated the association between race and risk of low- and high-grade PC in men undergoing initial prostate biopsy in an equal access medical center.

Methods

We conducted a retrospective record review of 887 men (48.6 % black, 51.4 % white) from the Durham Veterans Affairs Medical Center who underwent initial prostate biopsy between 2001 and 2009. Multivariable logistic regression analysis of race and biopsy outcome was conducted adjusting for age, body mass index, number of cores taken, prostate-specific antigen (PSA), and digital rectal examination findings. Multinomial logistic regression was used to test the association between black race and PC grade (Gleason <7 vs. ≥7).

Results

Black men were younger at biopsy (61 vs. 65 years, p < 0.001) and had a higher pre-biopsy PSA (6.6 vs. 5.8 ng/ml, p = 0.001). A total of 499 men had PC on biopsy (245 low grade; 254 high grade). In multivariable analyses, black race was significantly predictive of PC overall [odds ratio 1.50, p = 0.006] and high-grade PC [relative risk ratio (RRR) 1.84, p = 0.001], but was not significantly associated with low-grade PC (RRR 1.29, p = 0.139).

Conclusion

In an equal access healthcare facility, black race was associated with greater risk of PC detection on initial biopsy and of high-grade PC after adjusting for clinical characteristics. Additional investigation of mechanisms linking black race and PC risk and PC aggressiveness is needed.
