Invading of intrauterine contraceptive device into the sigmoid colon through uterine perforation caused by a blunt trauma.

Intrauterine contraceptive device (IUCD) is relatively safe but still with some serious risks. Uterus perforation is rare and would be fatal. A case of Cu-7 IUCD invading into the sigmoid colon through uterine perforation caused by a pelvic blunt trauma was presented. Our case showed that uterus perforation by an IUCD could induce utero-sigmoid fistula which is likely to be missed. Imaging is required when the patients with IUCD present abdominal pain, particularly with a history of trauma.

Perforated acute appendicitis in a pre-term neonate.

Acute appendicitis is a common occurrence in childhood, but this diagnosis is considered rarely in differential diagnosis of acute abdomen in the neonatal period because its occurrence is very rare in neonates. We report a 20-day- old afghan female baby that was admitted to neonatal intensive care unit, because of irritability and abdominal distension. Complete ultrasound of abdomen and pelvis was normal. In plain Radiographs of chest and abdomen with the exception of Air-filled stomach and intestine, there was no abnormality. Due to the lack of improvement and severe abdominal distension, she was transmitted to the operating room and Surgical exploration revealed perforated appendix. Appendicitis should be considered in the differential diagnosis for a neonate with abdominal distension and bilious vomiting and needs strong clinical suspicion.

Epidemiology of livestock-related injuries in a major trauma center in Kashan, Iran.

OBJECTIVE: Livestock-related injuries are one of the important factors causing morbidity and mortality in patients admitted to hospital. Treatment of these patients is still a major problem in health care system. The aim of current study was to assess the epidemiology of livestock-related injuries in a major trauma center in Iran from 2006 to 2011. METHODS: In a prospective study, patients with livestock-related injuries who were consecutively admitted to the trauma center in Kashan, Iran between 2006 and 2011 were evaluated. The data collected included patient's demographics, place and nature of accident, damaged organ, educational level, transport and outcome. Data were expressed as mean +/- standard deviation. RESULTS: A total of 129 patients were included in this study, accounting for 0.3% of all trauma admission (40 273 cases). The mean age was (55.27 +/- 14.45) years. Men were affected four times more than women. Falling down from livestock is the main mechanism of trauma in all groups. Upper and lower extremities were most frequently injured (n equal to 72), followed by the head, neck and spine (n equal to 33 for each). There was one death resulting from livestock-related injury in this study. CONCLUSION: Despite the low incidence, livestock-related injuries can damage major organs of human body and therefore appropriate training program to increase the safety awareness in home and outdoor is very important.

Chest Injury Evaluation and Management in Two Major Trauma Centers of Isfahan Province, IR Iran.

BACKGROUND: Chest trauma is responsible for 50% of deaths due to trauma. This kind of death usually occurs immediately after the trauma has occurred. OBJECTIVES: The aim of this study was to evaluate the various aspects of chest trauma in patients admitted to two main trauma centers located in the Isfahan Province, Iran. PATIENTS AND METHODS: During a six month period, a cross-sectional study of 100 patients who had sustained a chest injury was carried out. Data, including; age, sex, time of accident, trauma mechanism, organ injury, hospitalization length, complications, and patient outcomes were recorded and analyzed. RESULTS: The mean ages of the patients were 24.7 ± 3.1 years. Men were injured four times more often than the women. Blunt trauma was the most common type of injury. The incidence of hemothorax was 38% in blunt traumas, and 45% (P = 0.01) in penetrating ones. The incidence of pneumothorax was 43% in blunt traumas and 20% in penetrating ones (P = 0.03). The length of hospitalization was 7.2 ± 3.2 days for blunt and 10.1 ± 3.1 days for penetrating chest traumas. Five patients (5%) died during hospitalization, three of those deaths were due to arterial injuries and two cases were due to lung contusions. CONCLUSIONS: Since hemothorax is the main complication of blunt chest trauma in young men, we recommend that special consideration needs to be made to any case of chest trauma, especially blunt chest injuries.

Omental torsion after repeated abdominal blunt trauma.

Omental torsion is caused by the rotation of the greater omentum on its axis which may lead to tissue infarction and necrosis. It is a rare cause of acute abdomen. Signs, symptoms and paraclinical data are not specific. The patients usually undergo laparotomy for acute abdomen of poorly defined origin. High index of suspicious is required for the diagnosis of this entity. The diagnosis is usually confirmed after an explorative laparotomy. We present clinical characteristics and imaging findings of omental torsion in a young man following repeated blunt abdominal trauma.

Identification of the midgut microbiota of An. stephensi and An. maculipennis for their application as a paratransgenic tool against malaria.

The midgut microbiota associated with Anopheles stephensi and Anopheles maculipennis (Diptera: Culicidae) was investigated for development of a paratransgenesis-based approach to control malaria transmission in Eastern Mediterranean Region (EMR). Here, we present the results of a polymerase chain reaction (PCR) and biochemical-based approaches to identify the female adult and larvae mosquitoe microbiota of these two major malaria vectors, originated from South Eastern and North of Iran. Plating the mosquito midgut contents from lab-reared and field-collected Anopheles spp. was used for microbiota isolation. The gram-negative and gram-positive bacterial colonies were identified by Gram staining and specific mediums. Selected colonies were identified by differential biochemical tests and 16S rRNA gene sequence analysis. A number of 10 An. stephensi and 32 An. maculipennis adult mosquitoes and 15 An. stephensi and 7 An. maculipennis larvae were analyzed and 13 sequences of 16S rRNA gene bacterial species were retrieved, that were categorized in 3 classes and 8 families. The majority of the identified bacteria were belonged to the γ-proteobacteria class, including Pseudomonas sp. and Aeromonas sp. and the others were some closely related to those found in other vector mosquitoes, including Pantoea, Acinetobacter, Brevundimonas, Bacillus, Sphingomonas, Lysinibacillus and Rahnella. The 16S rRNA sequences in the current study aligned with the reference strains available in GenBank were used for construction of the phylogenetic tree that revealed the relatedness among the bacteria identified. The presented data strongly encourage further investigations, to verify the potential role of the detected bacteria for the malaria control in Iran and neighboring countries.
