Helicobacter pylori present in caries sample among dental caries patients.

Helicobacter pylori is Gram negative bacteria, the reason for causing peptic ulcer. There is suggestion between the presence of H. pylori in oral cavity and gastritis. The present study aimed to detect H. pylori in dental caries samples. The study included 29 dental caries patients from both sexes (13 males and 16 females), with different age groups (children and adult), and nine apparently healthy subject as a control group (2 males & 7 females). Dental caries samples were collected and investigated for this study from patients with dental caries who visited the Dental Faculty in the College of Dentistry, University of Babylon, Iraq. H. pylori antigen was detected using an enzyme linked immunosorbent assay (ELISA) technique. Of the 29 dental caries patients, 19 (65.51%) patients were positive for H. pylori antigen test. Most of them were in the age group 20-30 (9 patients) & 30-40 (8 patients). The age groups (10-20) & (40-50) years shows 100% positivity for H. pylori antigen. Also, result was recorded significant higher difference's between H. pylori positive antigen between dental caries patients and H. pylori positive antigen among control group. (t=2.697,df=5, p≤ 0.05). Pearson correlation recorded significantly higher association between the presence of H. pylori antigen and the dental caries infection among test group (r=1, p≤ 0.000), 4 (44.5%) of the 9 control subjects, without dental caries, were positive for H. pylori antigen test. In summary, the H. pylori positive antigen test was recorded in both dental caries patients (65.51%) and in the control group (62.5 %). In conclusion, H. pylori antigen was present in dental caries patients. This could indicate that the bacteria H. pylori present in dental caries samples may contribute to caries processes.

Subungual hematoma: clinical appearance of resolution over time.

Subungual hemorrhage is usually a benign sign, often linked to a traumatic cause. However, it can also reveal a serious and chronic systemic disease. As we will show, subungual hemorrhage may be an indicator of the severity of diabetic microangiopathy. We report a case of subungual hemorrhage in diabetes.

Epidemiological review of scorpion stings in Qatar. The need for regional management guidelines in emergency departments.

OBJECTIVES: To review the epidemiology of scorpion sting in Qatar, to explore both the clinical significance, and the role of the emergency department (ED) in the management of such cases. METHODS: In this retrospective study, we reviewed the records of all scorpion sting cases presented to the ED of Hamad General Hospital, Doha, Qatar between October 2010 and May 2013. RESULTS: A total of 111 cases of scorpion stings were reviewed, 81 (72.9%) were males and 30 (27.1%) were females, with a mean age of 38 years. Localized pain was the most frequent presenting complaint (89 [80.2%]), whereas localized redness (44 [39.6%]) and swelling (38 [34.2%]) were the most common clinical signs. Abroug's classification was used, and all cases  were found to be class I. All patients received symptomatic treatment and were sent home. CONCLUSION: Scorpion sting problem in Qatar has a low clinical significance. Data from such studies should be utilized to create more specific (local) management guidelines, which should be more efficient with more rational utilization of ED resources.

[Actinomycosic mycetoma of the foot in Morocco due to Actinomycetes viscosus]. / Mycétome actinomycosique du pied à Actinomycetes viscosus au Maroc.

We present the case of an actinomycotic mycetoma of the foot due to Actinomycetes viscosus. It evolved for nine years on the foot of a 26-year-old patient from a rural environment: Douar Inezgane (city in southern Morocco). Bacteriological study of the skin and grains confirmed the diagnosis. It showed positive bacilli on direct examination and on Gram staining and in positive culture. Histological study showed a polymorphous granulomatous inflammation without signs of malignancy with actinomycotic grains. Then we retained the diagnosis of primary cutaneous actinomycosis without visceral locations. The treatment was based on antibiotics: penicillin G by intravenous infusion for five weeks, relayed orally by amoxicillin associated with trimethoprim-sulfamethoxazole for long periods. After six months of treatment, we observed a favorable outcome with reduction of the swelling, nodules, lymphadenopathy, fistula's number and extension of time of issue of grains. The current follow up is 15 months. The primary cutaneous actinomycosis is still relevant in Morocco.
