<span class="fontstyle0"><strong>Background:</strong> </span><span class="fontstyle2">Diabetes mellitus (DM) has a broad spectrum of complications and comorbidities. Delayed wound healing is a major reason for infections and further life-threatening complications; the process of vascularization and tissue regeneration as well as anti-inflammatory and anti-oxidant reactions of the body are impaired in DM. Matricaria Chamomilla (MC) is a herbal medicine which has antimicrobial, antioxidant and wound healing potentials.<br /></span><strong><span class="fontstyle0">Objectives: </span></strong><span class="fontstyle2">In this study, these potentials are evaluated on full thickness diabetic excisional skin wounds by using stereological methods.<br /></span><strong><span class="fontstyle0">Methods: </span></strong><span class="fontstyle2">In this experimental study, 48 male Wistar rats with streptozotocin (STZ)-induced diabetes (50 mg/kg intraperitoneally) were divided into 4 groups (n = 12) randomly: MC 5% gel treated, MC 10% gel treated, gel-base treated group, and the control group receiving no treatment. After creating 1 cm</span><span class="fontstyle2">2 </span><span class="fontstyle2">wounds, rats were treated every 24 hours for 15 days.

<span class="fontstyle0">A 7.3-magnitude earthquake recently shook the Ezgeleh district, located about 143 km from Kermanshah city (12/11/2017), in the western part of the country. Due to the severity of the earthquakes and the infrastructure of the nearby cities and villages, a large number of victims needed medical treatment. Since earthquakes are natural disaster, the state of unpreparedness of the health care systems against natural disasters is unusual. Therefore, the aim of this paper was to assess this critical situation and better prepare for subsequent earthquakes.</span>

<strong><span class="fontstyle0">Introduction: </span></strong><span class="fontstyle2">Posterior interosseous nerve (PIN) palsy gives rise to various symptoms. The PIN due to lipoma is rare. Here, we report a case of progressive loss of finger extension due to a giant painless parosteal lipoma.<br /></span><span class="fontstyle0"><strong>Case Presentation:</strong> </span><span class="fontstyle2">A 52-year-old patient with progressive weakness of finger extension with diagnosis of posterior interosseous nerve (PIN) palsy was referred to our clinic. Electrophysiological studies showed a right PIN neuropathy at the level of the forearm. The patient had no history of trauma of the hand. The patient underwent surgery for tumor removal and nerve decompression. The loss of finger extension due to PIN palsy gradually recovered after tumor removal and the nerve recovered from the motor deficits. The patient showed no recurrence of motor deficit after the surgery in the follow-up.<br /></span><span class="fontstyle0"><strong>Conclusions:</strong> </span><span class="fontstyle2">Since PIN palsy may arise from lipoma early surgical exploration and the excision of deep-seated lipoma in the proximal forearm is recommended in order to avoid permanent damage to PIN or other branches of the radial nerve.</span>

<span class="fontstyle0"><strong>Background:</strong> </span><span class="fontstyle2">ZMC fractures are the second most common trauma of the face. Therefore, their treatment (including methods of fixation) is of clinical significance.<br /></span><span class="fontstyle0"><strong>Objectives:</strong> </span><span class="fontstyle2">Due to the lack of studies on many resorbable and non-resorbable fixations of the zygoma, this finite element analysis assessed for the first time displacements and dynamics of the zygoma fixed using three 1-point resorbable and three non-resorbable plates under normal and severe mastication forces.<br /></span><strong><span class="fontstyle0">Methods: </span></strong><span class="fontstyle2">After creating the 3Dmodelof the zygoma and its adjacent bones basedon aCT scanof amale patient,with linearfractures but without severe dislocations, three one-point resorbable and three similar one-point non-resorbable mini-plates were used to fix the zygoma with miniscrews. The zygomaticomaxillary buttress (ZMB), infraorbital rim, and frontozygomatic (FZ) suture were stabilized using L-shaped four-hole, curved five-hole, four-hole miniplates, respectively. The simulated zygoma was subjected to 150N and 750N loads. Minimum and maximum of stresses, strains, displacements, and rotational displacements of the zygoma were measured.<br /></span><strong><span class="fontstyle0">Results: </span></strong><span class="fontstyle2">All four parameters were much smaller in non-resorbable fixations compared to resorbable ones. In severe maxillary force, the parameters stress, strain, and displacement increase considerably. Among these, FZ might cause smaller displacements. Resorbable plates might not be optimum choices for one-point fixation of cases with the heavy mastication loads.</span>

<span class="fontstyle0"><strong>Background:</strong> </span><span class="fontstyle2">Flexor tendon damagemakes up a small number of total hand injuries; butmanagement of these injuries often poses a surgical challenge because the results remain unpredictable despite all efforts. The results of flexor tendon repair damage of both deep and superficial injuries, especially in zone II, despite using various methods, still remains poor.<br /></span><strong><span class="fontstyle0">Objectives: </span></strong><span class="fontstyle2">This study aimed to assess results of flexor digitorum profundus (FDP) repair with resection of flexor digitorum superficialis (FDS) stump in a setting where both tendons are transected.

<span class="fontstyle0"><strong>Background:</strong> </span><span class="fontstyle2">Blunt chest trauma is the third most important injury in patients with multiple trauma, thus the appropriate diagnosis is critical. Although chest X-rays (CXRs) are the most common diagnostic method, the physician should detect the imaging necessity and modality. Accordingly, NEXUS chest and thoracic injury rule-out criteria (TIRC) have been developed to prevent unnecessary radiographs in traumatized patients.<br /></span><span class="fontstyle0"><strong>Objectives:</strong> </span><span class="fontstyle2">In this study, the diagnostic accuracy of these two guidelines was compared in patients with multiple trauma.<br /></span><strong><span class="fontstyle0">Methods: </span></strong><span class="fontstyle2">In this cross-sectional study, eligible patients with chest blunt trauma, who referred to the Emergency Department of Imam Hossein Hospital from July 2016 to March 2018, were recruited. Demographic data, trauma and clinical information, and radiographic reports were recorded and the necessity of CXR was determined based on NEXUS chest and TIRC. Finally, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were also calculated for NEXUS chest and TIRC.<br /></span><span class="fontstyle0"><strong>Results:</strong> </span><span class="fontstyle2">In this study, 1925 patients with a mean age of 43.7 </span><span class="fontstyle3">± </span><span class="fontstyle2">9.16 years were evaluated (55% male). The sensitivity, specificity, PPV, NPV of TIRC in the diagnosis of traumatic chest injury were 93.6%, 84.9%, 24.03%, and 99.6%, respectively, and those of NEXUS in the diagnosis of traumatic chest injuries were 97.84%, 51.80%, 93.43%, and 99.79%, respectively. There was no significant difference in diagnostic accuracy between TIRC and NEXUS chest models.<br /></span><strong><span class="fontstyle0">Conclusions: </span></strong><span class="fontstyle2">This study showed that NEXUS chest and TIRC have equal values in predicting traumatized chest injuries. Parameters of TIRC are easily measurable in ED and do not require subjective assessments, such as mechanisms and velocity of trauma or fall height. Therefore, the TIRC model seems to be a better tool than NEXUS in detecting injury to the chest and reducing the risk of radiation exposure.</span>
