Epidemiology of Shigella-Associated diarrhea in Gorgan, north of Iran

Objective : Shigella is an important etiological agent for diarrhea and especially dysentery. Shigellosis is an intestinal infection that is a major public health problem in many developing countries. The aim of this study was to evaluate the prevalence of Shigella and its various species in diarrheal samples in Gorgan located in the north of Iran. Materials and Methods: Between January-December 2005, the epidemiology of Shigella- associated diarrhea was studied among 634 patients in Gorgan. The diarrheal samples accompanied with a questionnaire, which contained the demographic and main symptoms of the patients, were transported to the laboratory and inoculated in different culture media. Colonies suspected to be of Shigella were detected using differential biochemical tests and subsequently, the serotype of Shigella was defined using antisera. Results : Shigella was isolated from 56/634 diarrheal samples) (8.8%) of which S. sonnei was the predominant species (55%). Occurrence of Schigella was highest in the 2-5 years′ age group (70.9%) and highest in summer (73.2%) with the most frequent clinical manifestation being abdominal pain (67.8%). The prevalence of Shigella in males and females was 8 and 9.8% respectively, but this difference was not statistically significant. Conclusion: It has been shown that Shigella sonnei is the most common Shigella serogroup among 2-5 year-old children in Gorgan. It is therefore suggested that hygienic training be given to childcare attendants and the children themselves

Minimal Invasive Ostheosintesis For Treatment Of Diaphiseal Transverse Humeral Shaft Fractures

Objective: To evaluate patients with transverse fractures of the shaft of the humerus treated with indirect reduction and internal fixation with plate and screws through minimally invasive technique. Methods: Inclusion criteria were adult patients with transverse diaphyseal fractures of the humerus closed, isolated or not occurring within 15 days of the initial trauma. Exclusion criteria were patients with compound fractures. Results: In two patients, proximal screw loosening occurred, however, the fractures consolidated in the same mean time as the rest of the series. Consolidation with up to 5 degrees of varus occurred in five cases and extension deficit was observed in the patient with olecranon fracture treated with tension band, which was not considered as a complication. There was no recurrence of infection or iatrogenic radial nerve injury. Conclusion: It can be concluded that minimally invasive osteosynthesis with bridge plate can be considered a safe and effective option for the treatment of transverse fractures of the humeral shaft.

Use Of The Vascularized Iliac-crest Flap In Musculoskeletal Lesions.

Bone loss was in the past treated by several methods, such as bone distraction and the use of nonvascularized or tissue-bank bone grafts. With the advent of modern microsurgical techniques, the vascularized bone flap has been used with good results; it resolves local nutritional problems, repairs soft tissue that is often damaged by severe trauma, and treats bone loss due to tumors, pseudarthroses, and osteomyelitis. This paper reports the authors' experience with the use of vascularized iliac-crest flaps to treat orthopedic pathologies in five patients with traumatic bone loss (<10 cm), three with osteomyelitis, and three with atrophic nonunion. In all cases, the same surgeon obtained a vascularized iliac-crest flap with a pedicle based on the deep iliac circumflex artery. All flaps consolidated within a mean period of 3 months. These findings demonstrate that the use of an iliac-crest flap is a treatment option in cases of bone loss and that it is associated with good functional results and minimal donor-site morbidity.201323714

No evidence of association between CTLA-4 polymorphisms and systemic lupus erythematosus in Iranian patients

Aim: Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is an important negative regulator of T-cell responses. CTLA-4 polymorphisms have been confirmed to be associated with several autoimmune diseases such as systemic lupus erythematosus (SLE). We analyzed the role of CTLA-4 polymorphism at positions -1661 and -1722 in Iranian patients suffering from SLE. Methods: One hundred and eighty SLE patients and 304 ethnically and age-matched healthy controls were studied. Polymerase chain reaction restriction fragments length polymorphism (PCR-RFLP) was used to analyze the genotype and allele frequencies of these polymorphisms. Results: There was no significant association between the studied genotypic and allelic frequencies between SLE patients and the controls. Although the TC genotype in 1722TC polymorphism was more common among the control group, the correlation was not statistically significant. Conclusion: Our results suggest that the -1661AG and -1722TC polymorphisms in the promoter region of the CTLA-4 gene does not play any role in genetic susceptibility to SLE. However, further studies on larger sample sizes are needed to approve our results. © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd

Can spontaneous pneumothorax be resolved in COVID-19 without hospital care? A case report

Background: We encountered the novel coronavirus infection as a pandemic in 2020. The infection started in Wuhan, China, and spread rapidly all over the world. CT scan has been used as an important diagnostic method in the detection of suspicious patients. One of the uncommon complications of coronavirus disease 2019 (COVID-19) is pneumothorax. Case presentation: A 47-year-old smoker male with COVID-19 diagnosis, good general condition and no respiratory complaint, complicated by pneumothorax. He refused hospitalization. After educating him about the red flags and quarantine protocols, he continued treatment at home .Cap amoxicillin/clavulanic acid 625mg was prescribed for one week. A follow-up CT represented only small involvement of lungs. Pneumothorax was resolved spontaneously without any medical intervention and hospitalization. O2 saturation was in normal range an there was no dry cough anymore. Conclusion: According to our clinical experience, pneumothorax is resolved spontaneously in a COVID-19 case. Considering general status and hemodynamic stability, it is suggested to reduce invasive interventions in COVID-19 cases with pneumothorax. © The Author(s
