ABSTRACT
INTRODUCTION: Daily use of public restrooms may have a significant impact on spreading infectious diseases. Human society could be affected by spreading of transitional infectious diseases through feces, urinary tract infection and poor personal hygiene. According to the World Health Organization reports, plenty of people's developed diseases caused by contaminated public restrooms that may result in severe health problems. METHODS: This descriptive cross-sectional study was conducted on 7,482 samples that were collected randomly in 6 months (spring and summer 2019) in different regions of Tehran. The Data were obtained by analyzing 804 restroom's indoor and outdoor handles, 1062 toilet faucet, 826 washbasin taps, 1,062 toilet hoses, 804 flush tank levers, 643 soap dispenser bottoms, 643 liquid soaps, 99 bar soaps, 169 toilet papers and paper towels, and 50 hand dryer machines. Samples which were tested, based on bacteriology standard methods. RESULT: 7,482 samples were gathered of which 6,678 contaminated cases (89.25%) were observed and 804 cases (10.75%) were found non-contaminated. Escherichia coli with 28.48% and Pseudomonas with 0.39% were the most and the least common bacteria, respectively, in this study. CONCLUSION: The required tests to identify the bacteria that cause contamination through the use of public restrooms have been done. It is essential to inform the public of the mentioned items and teach how to prevent infectious diseases.
ABSTRACT
OBJECTIVES: In this study, the EEG findings in children with migraine headache were assessed in Bahrami Hospital, Tehran, Iran from 2014 to 2016. MATERIALS & METHODS: In this observational cross-sectional study, 71 consecutive children with migraine headache were enrolled. The EEG findings were determined and compared with other variables. RESULTS: There were 25 cases (35.2%) with abnormal EEG and the type of EEG abnormality comprised slow waves and sharp waves in 19(68%) and 8(32%) patients, respectively. CONCLUSION: Nearly one-third of children with migraine might have abnormal EEG.
ABSTRACT
PURPOSE: Group A streptococcal (GAS) pharyngitis is a common disease worldwide. We aimed to establish a pragmatic program as a clinical decision rule for GAS pharyngitis diagnosis. MATERIALS AND METHODS: This article derived from a research project on children aged 6-15 years. Five hundred and seventy-one children met the enrollment criteria on whom throat culture and validities of clinical findings were assessed in positive and negative throat culture groups. RESULTS: Positive GAS throat culture group included 99 (17.3%) patients with a positive culture. Negative GAS throat culture group included 472 (82.6%) patients. Exudate or enlarged tender nodes each one had 63% and 68% sensitivity and 31.5% and 37.5% specificity with a high percentage of negative predictive value (NPV) 80.54% and 85.09%, respectively. Sequence test revealed validities of exudate plus enlarged nodes at 43.62% sensitivity and 57.19% specificity with 83% NPV. CONCLUSIONS: High NPV of 83% indicated that similar prevalence in the absence of either exudate or enlarged tender lymph nodes. Probability of GAS negative throat cultures among children suspected of GAS pharyngitis was 83% and would correctly not receive inopportune antibiotics.
ABSTRACT
INTRODUCTION: Peutz-Jeghers syndrome (PJS) is a rare disorder characterized by mucocutaneous perioral pigmentation, gastrointestinal hamartomatous polyposis, and an increased risk of malignancy. Families with PJS may show a variable spectrum of manifestations in spite of their consecutive generations. A probable explanation is novel mutations in contributing genes. CASE PRESENTATION: This report describes 3 cases of a family. Two daughters presented the classic PJS, while their father only manifested mucocutaneous perioral pigmentation. The junior daughter was underwent 3 and the eldest daughter 2 laparotomies for intussusception. The patients were visited annually and their medical findings were recorded during a follow-up period of 14 years. They were periodically examined in our hospital and despite conveying diffuse polyposis from the esophagus throughout the rectum in these three cases, even a simple hyperplasia was not found in obtained specimens. CONCLUSIONS: The patients with diffuse PJS may be asymptomatic and without gastrointestinal or extragastrointestinal malignancies.
