Screening for Syphilis in Cases of Suspected Gonorrhea and Chlamydia Infections

Background. In all cases of suspected sexually transmitted infections (STIs), it has been routine practice to screen for syphilis with a blood sample. The incidence of syphilis seems to be lower than that of commonly screened STIs. Objective. The objective of our study was to determine whether it is cost-effective to screen for syphilis with serological testing in cases of suspected gonorrhea and chlamydia infections. Hypothesis. Our hypothesis is that it is not cost-effective to screen for syphilis in cases of presumed gonorrhea and chlamydia infections. Methods. Our study is a New York Medical College institutional review board–approved retrospective study. During the period January 2004 to August 12, 2006, the laboratory work of all patients tested for gonorrhea and chlamydia in our emergency department was reviewed. The charts were reviewed for the following tests: gonorrhea DNA probe, chlamydia DNA probe, and syphilis IgG (immunoglobulin G)/RPR (rapid plasma reagin). The results of these tests were obtained and analyzed. Results. The total number of patients screened for gonorrhea and chlamydia during this period was 196. Seventy-eight patients tested positive for gonorrhea and chlamydia. All these 78 patients, tested negative for syphilis. The overall prevalence of positivity for STIs was 39.8% (78/196). The prevalence of chlamydia alone was 85.9% (67/78) and gonorrhea alone was 7.69% (6/78). The prevalence of combined both chlamydia and gonorrhea was 6.4% (5/78). Statistics. We used online SILICO 2 × 4 Fisher exact test. By comparing positive and negative results of serology RPR, GC, and chlamydia trap, the resultant 2-tailed P value isConclusions. Per our study, the yield of syphilis testing was negligible. It may not be cost-effective to screen for syphilis in cases of STIs such as gonorrhea and chlamydia

Effect of Chloroethane Spray in the Treatment of Spastic Torticollis in Children and Adolescents

Objective . A study to determine the efficacy of chloroethane spray compared to normal saline in the treatment of spastic torticollis in children and adolescents. Hypothesis . Chloroethane spray is more superior to normal saline for the treatment of spastic torticollis in children and adolescents in the pediatric emergency room. Design . Prospective randomized study. Setting . Urban inner-city hospital pediatric emergency department. Methods and Results . All children and adolescents (between the ages of 1 and 16 years) presenting to the author with the complaint of stiff neck were enrolled in the study. A total of 132 patients were enrolled. After complete evaluation to rule out cervical spine injury, a central neurological cause, patients were enrolled in the study. Sixty-six patients were treated with chloroethane spray to the neck and the other 66 were given normal saline as placebo. Sixty-three out of 66 patients treated with chloroethane spray achieved relief in 5 minutes as demonstrated by painless and free movement of the head and neck. No adverse effects were observed. The patients treated with placebo have no relief in 5 minutes. To test the null hypothesis that the percentages improved in the 2 groups equally, we calculated the Z statistic. The Z statistic of 24 corresponded to a P value of <.0001, whether the test is 1-sided or 2-sided. Chloroethane spray treatment was superior to placebo with a high statistical significance. Conclusion . For children and adolescents with spastic torticollis chloroethane spray was more superior to normal saline in the pediatric emergency room

Usefulness of Leukocyte Esterase Test Versus Rapid Strep Test for Diagnosis of Acute Strep Pharyngitis

Objective: A study to compare the usage of throat swab testing for leukocyte esterase on a test strip(urine dip stick-multi stick) to rapid strep test for rapid diagnosis of Group A Beta hemolytic streptococci in cases of acute pharyngitis in children. Hypothesis: The testing of throat swab for leukocyte esterase on test strip currently used for urine testing may be used to detect throat infection and might be as useful as rapid strep. Methods: All patients who come with a complaint of sore throat and fever were examined clinically for erythema of pharynx, tonsils and also for any exudates. Informed consent was obtained from the parents and assent from the subjects. 3 swabs were taken from pharyngo-tonsillar region, testing for culture, rapid strep & Leukocyte Esterase. Results: Total number is 100. Cultures 9(+); for rapid strep== 84(-) and16 (+); For LE== 80(-) and 20(+) Statistics: From data configuration Rapid Strep versus LE test don’t seem to be a random (independent) assignment but extremely aligned. The Statistical results show rapid and LE show very agreeable results. Calculated Value of Chi Squared Exceeds Tabulated under 1 Degree Of Freedom (P<.0.0001) reject Null Hypothesis and Conclude Alternative Conclusions: Leukocyte esterase on throat swab is as useful as rapid strep test for rapid diagnosis of strep pharyngitis on test strip currently used for urine dip stick causing acute pharyngitis in children

A Study to Determine the Incidence of Urinary Tract Infections in Infants and Children Ages 4 Months to 6 Years With Febrile Diarrhea

Objective: To determine the incidence of urinary tract infections (UTIs) in infants and children (4 months to 6 years of age) with febrile diarrhea, as outpatients. Methods: This was a prospective institutional review board–approved study. patients (between 4 months and 6 years of age) were enrolled in the study who presented to the pediatric emergency room with a complaint of fever (rectal temperature 101°F or more) and diarrhea (watery stools >3 in number). The patients were evaluated for state of hydration, and also urine samples were collected. For those children not toilet trained, urine specimens were collected by bladder catheterization, and for those children toilet trained, urine specimens were obtained by midstream collection method. The urine samples obtained were sent for analysis and culture. Results: Eighty patients were enrolled in the study. The number of specimens obtained by clean catch midstream was 20, and by bladder catheterization was 60. None of the urine specimens obtained by both methods of collection grew any organism. There was no increased incidence of infections in male children whether circumcised (10/60) or uncircumcised (50/60). The mean temperature was 102.8°F (range = 101°F to 105°F). Statistics: Using in silico online 2 × 2 χ 2 test by comparing both the positive and negative urine culture results, 2-tailed P value is <.0001. Conclusions: Our prospective randomized study concluded that there is no increased incidence of UTIs in infants and children (4 months to 6 years of age) with febrile diarrhea

A Study to Determine if Addition of Palatal Petechiae to Centor Criteria Adds More Significance to Clinical Diagnosis of Acute Strep Pharyngitis in Children

Objective . A study to determine if addition of palatal petechiae to Centor criteria adds more value for clinical diagnosis of acute strep pharyngitis in children. Hypothesis . In children, Centor Criteria does not cover all the symptoms and signs of acute strep pharyngitis. We hypothesize that addition of palatal petechiae to Centor Criteria will increase the possibility of clinical diagnosis of group A streptococcal pharyngitis in children. Methods . One hundred patients with a complaint of sore throat were enrolled in the study. All the patients were examined clinically using the Centor Criteria. They were also examined for other signs and symptoms like petechial lesions over the palate, abdominal pain, and skin rash. All the patients were given rapid strep tests, and throat cultures were sent. No antibiotics were given until culture results were obtained. Results . The sample size was 100 patients. All 100 had fever, sore throat, and erythema of tonsils. Twenty of the 100 patients had tonsillar exudates, 85/100 had tender anterior cervical lymph nodes, and 86/100 had no cough. In total, 9 out of the 100 patients had positive throat cultures. We observed that petechiae over the palate, a very significant sign, is not included in the Centor Criteria. Palatal petechiae were present in 8 out of the 100 patients. Six out of these 8 with palatal petechiae had positive throat culture for strep (75%). Only 7 out of 20 with exudates had positive strep culture. Sixteen out of the 100 patients had rapid strep test positive. Those 84/100 who had negative rapid strep also had negative throat culture. Statistics . We used Fisher’s exact test, comparing throat culture positive and negative versus presence of exudates and palatal hemorrhages with positive and negative throat cultures and the resultant P value <.0001. Conclusion . Our study concludes that addition of petechiae over the palate to Centor Criteria will increase the possibility of diagnosing acute group A streptococcal pharyngitis in children
