Background Several studies worldwide have investigated household product poisoning. We conducted a toxico-clinical study on the two-year prevalence of poisoning with household products. Methods This cross-sectional study was performed in Khorshid Hospital, the main referral center for poisoning cases in Isfahan, affiliated to Isfahan University of Medical Sciences, Isfahan, central Iran. All patients with intentional or unintentional household substance poisoning, referring to the poisoning emergency center of the hospital, were evaluated with respect to epidemiological and toxico-clinical features and outcomes. Results During the study period, 5946 patients were hospitalized, of which 83 (1.39%) had been poisoned with household products including 48 (57.8%) men and 35 (42.2%) women with a mean ± SD age of 34.40 ± 17.71 years. Most patients (54.2%) were in the 20–40-year-old age group. Accidental poisoning (63.9%) was the most common type of exposure (P = 0.02) predominantly in men (57.8%, P = 0.51). The most common household products were sodium hypochlorite (32.53%) followed by petroleum hydrocarbon (21.68%). Most of the accidental poisonings (77.8%) were due to petroleum hydrocarbon. 59% of cases were poisoned at home (P < 0.0001). No patient died. Conclusion Household products were not common means of poisoning in our referral center. Sodium hypochlorite and petroleum hydrocarbon were the most common substances. Most of the patients were men with accidental exposure at home. Because of the availability of the household product, the frequency and outcomes may be varied in different societies.

An 81-year-old female presented with a loss of consciousness and a history of fever, dry cough, dyspnea, and conjunctivitis during 5 days ago. On initial physical examination, the laboratory examination revealed high levels of lactate dehydrogenase and creatinine concomitant severe thrombocytopenia. Moreover, the peripheral blood smear showed schistocytes 3%, suggesting thrombotic thrombocytopenic purpura (TTP). A ground-glass pattern was reported in the high-resolution computed tomography of the lung. A positive polymerase chain reaction was reported for coronavirus disease 2019 (COVID-19). After initiating treatment for COVID-19, the patient received fresh frozen plasma and 24-h electrocardiogram monitoring in the emergency department. As the patient was being prepared for transfer to another hospital for plasmapheresis treatment, cardiac arrest occurred again, and the patient passed away. This study highlights the atypical behavior of this virus over the course of the disease including TTP with conjunctivitis, which could vary from case to case.

Background The main activity of the skin is to create a protective barrier against damage. Loss of the skin due to injury or disease and failure to regenerate the affected area may result in disability, infection, or even death. We conducted a clinical trial to evaluate the therapeutic effect of dressing containing silver in process of healing skin blisters caused by limb fractures. Method This is a pioneering randomized trial that compares the effectiveness of two dressings containing silver (Ag coat) and Gaz Vaseline among patients with skin blisters due to bone fractures who were randomly selected from patients referred to the Kashani Medical Training Center. There were two treatment groups containing 16 patients treated with Ag coat and 15 patients treated with Gaz Vaseline. Pictures were taken of blisters on days 0, 7, and 14 to evaluate the healing process. The amount of pain, duration of the visit (measured by minutes), and general condition of the wound were checked. The amount of pain, duration of visit (measured by minutes) and general condition of the wound was checked. All continuous and categorical data are presented as mean ± standard deviation (SD) and frequency (percentage), respectively. Paired sample T-test and repeated measure analysis of variance (ANOVA), Chi-squared test was used. All pictures were analyzed by Mosaic soft ward. Result During this study, there was no significant difference between the mean of age and BMI and frequency of gender in the two study groups (P > 0.05). There was a significant difference in mean between the duration of the visit, number of dressings, and net cost of dressing $$(p <0.05)$$ ( p < 0.05 ) . In the macroscopic study and analysis for evaluation and comparing wound area with the Mosaic soft ward, there was significant relation in time (p1 = 0.00). There is no significant difference between the groups (p2 = 0.84). There was a significant difference between time and group (p3 = 0.00). On day 14 the wound area between groups had a significant difference (p4 = 0.00) (Table 3). In the VAS score there was a significant difference in time, and group (p1,2 = 0.00), there was no significant relation between time and group (p3 = 0.62). On all days the wound area between groups had a significant difference (p4 = 0.00). Conclusion In conclusion, Ag coat dressing, not only has a significant effect on wound healing but also, decreases pain, shorter visit time, and its more cost-effective.

Background: Complications after primary total hip arthroplasty (THA) are the most common reason for revision. Due to the high prevalence of revision surgery, we investigated the frequency of postprimary THA complications and related risk factor revision surgery. Materials and Methods: This is a cohort study that was performed in 2011–2019 on all patients who underwent primary THA surgery re-admitted to the Kashani and Saadi Hospital affiliated to Isfahan University of Medical Science, Iran, due to some complications after THA. Demographic and basic data were collected from patient's medical documents. Harris hip score (HHS) was calculated for all patients 6 months after the last surgery. The obtained data were analyzed using SPSS software version 21. Appropriate statistical tests were conducted to compare the results between the study groups. Results: Among 1260 patients who underwent primary THA, 1006 of them entered the study after applying the exclusion criteria. Thirty nine patients were under revision, 53.8% had prosthesis infection, 56.4% had instability, 6% had aseptic loosening, and 30.8% had periprosthetic fracture. Odds ratio for the above complications were 45.5, 45, 6.4, and 15.5, respectively. HHS postoperatively was also significantly ( P < 0.001) higher in patients without revision. No correlation between gender or surgeon experience and revision was detected; however wound discharge ( P < 0.001), body mass index (BMI) ( P = 0.003), and Infection during hospitalization ( P < 0.001) affect revision rate significantly. All four postsurgery complications, i.e., instability, postoperative prothesis infections, periprosthetic fractures, and aseptic loosening, significantly increased the risk of revision ( P < 0.001, for all). Conclusion: Instability, prosthetic infections, periprosthetic fractures, and aseptic loosening were the most common causes for increasing revision rates after THA, respectively. Higher BMI, persistent wound discharge, and nosocomial infections during the first hospitalization also increased the rate of revision after primary THA.
